Item 5.03                      Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On October 10, 2016, the shareholders of Avista Healthcare Public Acquisition Corp. (the “Company”) approved, pursuant to a special resolution by unanimous written consent, an amendment (the “Amendment”) to the Company’s Amended and Restated Memorandum and Articles of Association (as so amended, the “Articles”).  The Amendment requires that any amendment to the provisions of the Articles providing public shareholders with the right to redeem their public shares in the circumstances provided therein prior to completion of a business combination shall require the approval of the holders of 100% of the ordinary shares then-outstanding.

A copy of the Articles is filed with this Current Report on Form 8-K as Exhibit 3.1 and is incorporated herein by reference, and the foregoing description of the Articles is qualified in its entirety by reference thereto.

Item 5.07                      Submission of Matters to a Vote of Security Holders.

The information set forth under item 5.03 is incorporated herein by reference.

Item 8.01                      Other Events.

On October 14, 2016, the Company consummated its initial public offering (“IPO”) of 30,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Share”), and one warrant of the Company (“Warrant”) to purchase one-half of one Ordinary Share. Two Warrants may be exercised for one whole Class A ordinary share at a price of $11.50 per whole share. The Units were sold at a price of $10.00 per unit, generating gross proceeds to the Company of $300,000,000.

Simultaneously with the closing of the IPO, the Company completed the private sale of an aggregate of 16,000,000 warrants (the “Private Placement Warrants”), at a purchase price of $0.50 per Private Placement Warrant, to the Company’s sponsor, Avista Acquisition Corp. (the “Sponsor”), and the Company’s independent directors (collectively with the Sponsor, the “Initial Shareholders”), generating gross proceeds to the Company of $8,000,000. The Private Placement Warrants are identical to the warrants sold as part of the Units in the IPO, except that the Initial Shareholders have agreed not to transfer, assign or sell any of the Private Placement Warrants (except to certain permitted transferees) until 30 days after the completion of the Company’s initial business combination. The Private Placement Warrants are also not redeemable by the Company so long as they are held by the Initial Shareholders or their permitted transferees, and they may be exercised by the Initial Shareholders and their respective permitted transferees on a cashless basis.

A total of $300,000,000, comprised of $294,000,000 of the proceeds from the IPO, including $10,500,000 of the underwriters’ deferred discount and $6,000,000 of the proceeds of the sale of the Private Placement Warrants, were placed in a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee. Except with respect to interest earned on the funds in the trust account that may be released to the Company to pay its taxes, the proceeds from the IPO will not be released from the trust account until the earliest of (i) the completion of the Company’s initial business combination, (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company’s Articles to modify the substance or timing of its obligation to redeem 100% of its public shares if the Company does not complete its initial business combination within 24 months from the closing of the IPO and (iii) the redemption of all of the Company’s public shares if it is unable to complete its business combination within 24 months from the closing of the IPO, subject to applicable law.

On October 10, 2016, in connection with the IPO, the Company entered into the following agreements previously filed as exhibits to the Company registration statement (File No. 333-213465):

·                  A Warrant Agreement, dated as of October 10, 2016, between the Company and Continental Stock Transfer & Trust Company, as warrant agent.

3.1                               Subject to the provisions, if any, in the Memorandum (and to any direction that may be given by the Company in general meeting) and, where applicable, the rules of the Designated Stock Exchange and/or any competent regulatory authority, and without prejudice to any rights attached to any existing Shares, the Directors may allot, issue, grant options over or otherwise dispose of Shares (including fractions of a Share) with or without preferred, deferred or other rights or restrictions, whether in regard to Dividend or other distribution, voting, return of capital or otherwise and to such persons, at such times and on such other terms as they think proper, and may also (subject to the Statute and the Articles) vary such rights, save that the Directors shall not allot, issue, grant options over or otherwise dispose of Shares (including fractions of a Share) to the extent that it may affect the ability of the Company to carry out a Class B Share Conversion described at Article 17.

6

5                                         Closing Register of Members or Fixing Record Date

5.1                               For the purpose of determining Members entitled to notice of, or to vote at any meeting of Members or any adjournment thereof, or Members entitled to receive payment of any Dividend or other distribution, or in order to make a determination of Members for any other purpose, the Directors may, after notice has been given by advertisement in an appointed newspaper or any other newspaper or by any other means in accordance with the requirements of the Designated Stock Exchange, provide that the Register of Members shall be closed for transfers for a stated period which shall not in any case exceed forty days.

5.2                               In lieu of, or apart from, closing the Register of Members, the Directors may fix in advance or arrears a date as the record date for any such determination of Members entitled to notice of, or to vote at any meeting of the Members or any adjournment thereof, or for the purpose of determining the Members entitled to receive payment of any Dividend or other distribution, or in order to make a determination of Members for any other purpose.

5.3                               If the Register of Members is not so closed and no record date is fixed for the determination of Members entitled to notice of, or to vote at, a meeting of Members or Members entitled to receive payment of a Dividend or other distribution, the date on which notice of the meeting is sent or the date on which the resolution of the Directors resolving to pay such Dividend or other distribution is passed, as the case may be, shall be the record date for such determination of Members.  When a determination of Members entitled to vote at any meeting of Members has been made as provided in this Article, such determination shall apply to any adjournment thereof.

6                                         Certificates for Shares

6.1                               A Member shall only be entitled to a share certificate if the Directors resolve that share certificates shall be issued. Share certificates representing Shares, if any, shall be in such form as the Directors may determine.  Share certificates shall be signed by one or more Directors or other person authorised by the Directors. The Directors may authorise certificates to be issued with the authorised signature(s) affixed by mechanical process.  All certificates for Shares shall be consecutively numbered or otherwise identified and shall specify the Shares to which they relate.  All certificates surrendered to the Company for transfer shall be cancelled and, subject to the Articles, no new certificate shall be issued until the former certificate representing a like number of relevant Shares shall have been surrendered and cancelled.

6.2                               The Company shall not be bound to issue more than one certificate for Shares held jointly by more than one person and delivery of a certificate to one joint holder shall be a sufficient delivery to all of them.

6.3                               If a share certificate is defaced, worn out, lost or destroyed, it may be renewed on such terms (if any) as to evidence and indemnity and on the payment of such expenses reasonably incurred by the Company in investigating evidence, as the Directors may prescribe, and (in the case of defacement or wearing out) upon delivery of the old certificate.

7

6.4                               Every share certificate sent in accordance with the Articles will be sent at the risk of the Member or other person entitled to the certificate. The Company will not be responsible for any share certificate lost or delayed in the course of delivery.

6.5                               Share certificates shall be issued within the relevant time limit as prescribed by the Statute, if applicable, or as the Designated Stock Exchange may from time to time determine, whichever is shorter, after the allotment or, except in the case of a Share transfer which the Company is for the time being entitled to refuse to register and does not register, after lodgement of a Share transfer with the Company.

7                                         Transfer of Shares

7.1                               Subject to the terms of these Articles, any Member may transfer all or any of his Shares by an instrument of transfer provided that such transfer complies with applicable rules of the SEC and federal and state securities laws of the United States.  If the Shares in question were issued in conjunction with rights, options or warrants issued pursuant to Article 3 on terms that one cannot be transferred without the other, the Directors shall refuse to register the transfer of any such Share without evidence satisfactory to them of the like transfer of such option or warrant.

7.2                               The instrument of transfer of any Share shall be in writing in the usual or common form or in a form prescribed by the Designated Stock Exchange or in any other form approved by the Directors and shall be executed by or on behalf of the transferor (and if the Directors so require, signed by or on behalf of the transferee) and may be under hand or, if the transferor or transferee is a clearing house or its nominee(s), by hand or by machine imprinted signature or by such other manner of execution as the Directors may approve from time to time.  The transferor shall be deemed to remain the holder of a Share until the name of the transferee is entered in the Register of Members.

8                                         Redemption, Repurchase and Surrender of Shares

8.1                               Subject to the provisions of the Statute, and, where applicable, the rules of the Designated Stock Exchange and/or any competent regulatory authority, the Company may issue Shares that are to be redeemed or are liable to be redeemed at the option of the Member or the Company. The redemption of such Shares, except Shares in the IPO, shall be effected in such manner and upon such other terms as the Company may, by Special Resolution, determine before the issue of such Shares.  With respect to the Shares:

(a)                                 Members who hold Shares issued in the IPO are entitled to request redemption of such Shares in the circumstances described in Article 49.3;

(b)                                 shares held by the Sponsor shall be surrendered to the extent that the Over-allotment Option is not exercised in full so that the Founders will own 20% of the Company’s issued and outstanding Shares after the IPO (exclusive of any securities purchased in a private placement simultaneously with the IPO); and

(c)                                  shares issued in the IPO shall be redeemed by way of tender offer in the circumstances set out in Article 49.2(b).

8

8.2                               Subject to the provisions of the Statute, and, where applicable, the rules of the Designated Stock Exchange and/or any competent regulatory authority, the Company may purchase its own Shares (including any redeemable Shares) in such manner and on such other terms as the Directors may agree with the relevant Member.  For the avoidance of doubt, redemptions and surrenders of Shares in the circumstances described at Articles 8.1(a), 8.1(b) and 8.1(c) above shall not require further approval of the Members.

8.3                               The Company may make a payment in respect of the redemption or purchase of its own Shares in any manner permitted by the Statute, including out of capital.

8.4                               The Directors may accept the surrender for no consideration of any fully paid Share.

9                                         Treasury Shares

9.1                               The Directors may, prior to the purchase, redemption or surrender of any Share, determine that such Share shall be held as a Treasury Share.

9.2                               The Directors may determine to cancel a Treasury Share or transfer a Treasury Share on such terms as they think proper (including, without limitation, for nil consideration).

10                                  Variation of Rights of Shares

10.1                        If at any time the share capital of the Company is divided into different classes of Shares, all or any of the rights attached to any class (unless otherwise provided by the terms of issue of the Shares of that class) may, whether or not the Company is being wound up, be varied without the consent of the holders of the issued Shares of that class where such variation is considered by the Directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued Shares of that class (other than with respect to a waiver of the provisions of Article 17.2 hereof, which as stated therein shall only require the consent in writing of the holders of a majority of the issued Shares of that class), or with the sanction of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the Shares of that class. For the avoidance of doubt, the Directors reserve the right, notwithstanding that any such variation may not have a material adverse effect, to obtain consent from the holders of Shares of the relevant class.  To any such meeting all the provisions of the Articles relating to general meetings shall apply mutatis mutandis, except that the necessary quorum shall be one person holding or representing by proxy at least one third of the issued Shares of the class and that any holder of Shares of the class present in person or by proxy may demand a poll.

10.2                        For the purposes of a separate class meeting, the Directors may treat two or more or all the classes of Shares as forming one class of Shares if the Directors consider that such class of Shares would be affected in the same way by the proposals under consideration, but in any other case shall treat them as separate classes of Shares.

10.3                        The rights conferred upon the holders of the Shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the Shares of that

9

class, be deemed to be varied by the creation or issue of further Shares ranking pari passu therewith.

11                                  Commission on Sale of Shares

The Company may, in so far as the Statute permits, pay a commission to any person in consideration of his subscribing or agreeing to subscribe (whether absolutely or conditionally) or procuring or agreeing to procure subscriptions (whether absolutely or conditionally) for any Shares. Such commissions may be satisfied by the payment of cash and/or the issue of fully or partly paid-up Shares.  The Company may also on any issue of Shares pay such brokerage as may be lawful.

12                                  Non Recognition of Trusts

The Company shall not be bound by or compelled to recognise in any way (even when notified) any equitable, contingent, future or partial interest in any Share, or (except only as is otherwise provided by the Articles or the Statute) any other rights in respect of any Share other than an absolute right to the entirety thereof in the holder.

13                                  Lien on Shares

13.1                        The Company shall have a first and paramount lien on all Shares (whether fully paid-up or not) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other person, whether a Member or not, but the Directors may at any time declare any Share to be wholly or in part exempt from the provisions of this Article.  The registration of a transfer of any such Share shall operate as a waiver of the Company’s lien thereon.  The Company’s lien on a Share shall also extend to any amount payable in respect of that Share.

13.2                        The Company may sell, in such manner as the Directors think fit, any Shares on which the Company has a lien, if a sum in respect of which the lien exists is presently payable, and is not paid within fourteen clear days after notice has been received or deemed to have been received by the holder of the Shares, or to the person entitled to it in consequence of the death or bankruptcy of the holder, demanding payment and stating that if the notice is not complied with the Shares may be sold.

13.3                        To give effect to any such sale the Directors may authorise any person to execute an instrument of transfer of the Shares sold to, or in accordance with the directions of, the purchaser.  The purchaser or his nominee shall be registered as the holder of the Shares comprised in any such transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the Shares be affected by any irregularity or invalidity in the sale or the exercise of the Company’s power of sale under the Articles.

13.4                        The net proceeds of such sale after payment of costs, shall be applied in payment of such part of the amount in respect of which the lien exists as is presently payable and any balance shall (subject to a like lien for sums not presently payable as existed upon the Shares before the sale) be paid to the person entitled to the Shares at the date of the sale.

10

14                                  Call on Shares

14.1                        Subject to the terms of the allotment and issue of any Shares, the Directors may make calls upon the Members in respect of any monies unpaid on their Shares (whether in respect of par value or premium), and each Member shall (subject to receiving at least fourteen clear days’ notice specifying the time or times of payment) pay to the Company at the time or times so specified the amount called on the Shares.  A call may be revoked or postponed, in whole or in part, as the Directors may determine.  A call may be required to be paid by instalments.  A person upon whom a call is made shall remain liable for calls made upon him notwithstanding the subsequent transfer of the Shares in respect of which the call was made.

14.2                        A call shall be deemed to have been made at the time when the resolution of the Directors authorising such call was passed.

14.3                        The joint holders of a Share shall be jointly and severally liable to pay all calls in respect thereof.

14.4                        If a call remains unpaid after it has become due and payable, the person from whom it is due shall pay interest on the amount unpaid from the day it became due and payable until it is paid at such rate as the Directors may determine (and in addition all expenses that have been incurred by the Company by reason of such non-payment), but the Directors may waive payment of the interest or expenses wholly or in part.

14.5                        An amount payable in respect of a Share on issue or allotment or at any fixed date, whether on account of the par value of the Share or premium or otherwise, shall be deemed to be a call and if it is not paid all the provisions of the Articles shall apply as if that amount had become due and payable by virtue of a call.

14.6                        The Directors may issue Shares with different terms as to the amount and times of payment of calls, or the interest to be paid.

14.7                        The Directors may, if they think fit, receive an amount from any Member willing to advance all or any part of the monies uncalled and unpaid upon any Shares held by him, and may (until the amount would otherwise become payable) pay interest at such rate as may be agreed upon between the Directors and the Member paying such amount in advance.

14.8                        No such amount paid in advance of calls shall entitle the Member paying such amount to any portion of a Dividend or other distribution payable in respect of any period prior to the date upon which such amount would, but for such payment, become payable.

15                                  Forfeiture of Shares

15.1                        If a call or instalment of a call remains unpaid after it has become due and payable the Directors may give to the person from whom it is due not less than fourteen clear days’ notice requiring payment of the amount unpaid together with any interest which may have accrued and any expenses incurred by the Company by reason of such non-payment.  The notice shall specify where payment is to be made and shall state that if the notice is not complied with the Shares in respect of which the call was made will be liable to be forfeited.

11

15.2                        If the notice is not complied with, any Share in respect of which it was given may, before the payment required by the notice has been made, be forfeited by a resolution of the Directors.  Such forfeiture shall include all Dividends, other distributions or other monies payable in respect of the forfeited Share and not paid before the forfeiture.

15.3                        A forfeited Share may be sold, re-allotted or otherwise disposed of on such terms and in such manner as the Directors think fit and at any time before a sale, re-allotment or disposition the forfeiture may be cancelled on such terms as the Directors think fit.  Where for the purposes of its disposal a forfeited Share is to be transferred to any person the Directors may authorise some person to execute an instrument of transfer of the Share in favour of that person.

15.4                        A person any of whose Shares have been forfeited shall cease to be a Member in respect of them and shall surrender to the Company for cancellation the certificate for the Shares forfeited and shall remain liable to pay to the Company all monies which at the date of forfeiture were payable by him to the Company in respect of those Shares together with interest at such rate as the Directors may determine, but his liability shall cease if and when the Company shall have received payment in full of all monies due and payable by him in respect of those Shares.

15.5                        A certificate in writing under the hand of one Director or officer of the Company that a Share has been forfeited on a specified date shall be conclusive evidence of the facts stated in it as against all persons claiming to be entitled to the Share.  The certificate shall (subject to the execution of an instrument of transfer) constitute a good title to the Share and the person to whom the Share is sold or otherwise disposed of shall not be bound to see to the application of the purchase money, if any, nor shall his title to the Share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the Share.

15.6                        The provisions of the Articles as to forfeiture shall apply in the case of non payment of any sum which, by the terms of issue of a Share, becomes payable at a fixed time, whether on account of the par value of the Share or by way of premium as if it had been payable by virtue of a call duly made and notified.

16                                  Transmission of Shares

16.1                        If a Member dies, the survivor or survivors (where he was a joint holder), or his legal personal representatives (where he was a sole holder), shall be the only persons recognised by the Company as having any title to his Shares.  The estate of a deceased Member is not thereby released from any liability in respect of any Share, for which he was a joint or sole holder.

16.2                        Any person becoming entitled to a Share in consequence of the death or bankruptcy or liquidation or dissolution of a Member (or in any other way than by transfer) may, upon such evidence being produced as may be required by the Directors, elect, by a notice in writing sent by him to the Company, either to become the holder of such Share or to have some person nominated by him registered as the holder of such Share. If he elects to have another person registered as the holder of such Share he shall sign an instrument of transfer of that Share to that person. The Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution, as the case may be.

12

16.3                        A person becoming entitled to a Share by reason of the death or bankruptcy or liquidation or dissolution of a Member (or in any other case than by transfer) shall be entitled to the same Dividends, other distributions and other advantages to which he would be entitled if he were the holder of such Share. However, he shall not, before becoming a Member in respect of a Share, be entitled in respect of it to exercise any right conferred by membership in relation to general meetings of the Company and the Directors may at any time give notice requiring any such person to elect either to be registered himself or to have some person nominated by him be registered as the holder of the Share (but the Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution or any other case than by transfer, as the case may be). If the notice is not complied with within ninety days of being received or deemed to be received (as determined pursuant to the Articles), the Directors may thereafter withhold payment of all Dividends, other distributions, bonuses or other monies payable in respect of the Share until the requirements of the notice have been complied with.

17                                  Class B Share Conversion

17.1                        Class B Shares shall convert into Class A Shares on a one-for-one basis (the “Initial Conversion Ratio”) (a) at any time and from time to time at the option of the holder thereof and (b) automatically on the business day following the closing of a Business Combination.

17.2                        Notwithstanding the Initial Conversion Ratio, in the case that additional Class A Shares or any other equity linked securities, are issued or deemed issued in excess of the amounts sold in the IPO and related to the closing of the Business Combination, all issued and outstanding Class B Shares shall automatically convert into Class A Shares at the time of the closing of the Business Combination at a ratio for which:

(a)                                 the numerator shall be equal to the sum of (A) 25% of all Class A Shares issued or issuable (upon the conversion or exercise of any equity-linked securities or otherwise) by the Company, related to or in connection with the consummation of the Business Combination (excluding any securities issued or issuable to any seller in the Business Combination) plus (B) the number of Class B Shares issued and outstanding prior to the consummation of the Business Combination; and

(b)                                 the denominator shall be the number of Class B Shares issued and outstanding prior to the closing of the Business Combination.

Notwithstanding anything to the contrary contained herein, the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional Class A Shares or equity-linked securities by the written consent or agreement of holders of a majority of the Class B Shares then outstanding consenting or agreeing separately as a separate class in the manner provided in Article 10.

17.3                        The foregoing conversion ratio shall also be adjusted to account for any subdivision (by share split, subdivision, exchange, share dividend, rights issue, reclassification, recapitalization or otherwise) or combination (by reverse share split, share consolidation, exchange, reclassification, recapitalization or otherwise) or similar reclassification or recapitalization of the issued and

13

outstanding Class A Shares into a greater or lesser number of shares occurring after the original filing of these Articles without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalization of the outstanding Class B Shares.

17.4                        Each Class B Share shall convert into its pro rata number of Class A Shares pursuant to this Article 17. The pro rata share for each holder of Class B Shares will be determined as follows: each Class B Share shall convert into such number of Class A Shares as is equal to the product of 1 multiplied by a fraction, the numerator of which shall be the total number of Class A Shares into which all of the issued and outstanding Class B Shares shall be converted pursuant to this Article and the denominator of which shall be the total number of issued and outstanding shares of Class B Shares at the time of conversion.

17.5                        Notwithstanding anything to the contrary in this Article 17, in no event may any Class B Share convert into Class A Shares at a ratio that is less than one-for-one.

18                                  Amendments of Memorandum and Articles of Association and Alteration of Capital

18.1                        The Company may by Ordinary Resolution:

(a)                                 increase its share capital by such sum as the Ordinary Resolution shall prescribe and with such rights, priorities and privileges annexed thereto, as the Company in general meeting may determine;

(b)                                 consolidate and divide all or any of its share capital into Shares of larger amount than its existing Shares;

(c)                                  convert all or any of its paid-up Shares into stock, and reconvert that stock into paid-up Shares of any denomination;

(d)                                 by subdivision of its existing Shares or any of them divide the whole or any part of its share capital into Shares of smaller amount than is fixed by the Memorandum or into Shares without par value; and

(e)                                  cancel any Shares that at the date of the passing of the Ordinary Resolution have not been taken or agreed to be taken by any person and diminish the amount of its share capital by the amount of the Shares so cancelled.

18.2                        All new Shares created in accordance with the provisions of the preceding Article shall be subject to the same provisions of the Articles with reference to the payment of calls, liens, transfer, transmission, forfeiture and otherwise as the Shares in the original share capital.

18.3                        Subject to the provisions of the Statute, the provisions of the Articles as regards the matters to be dealt with by Ordinary Resolution and Article 49.1, the Company may by Special Resolution:

(a)                                 change its name;

(b)                                 alter or add to the Articles (subject to Article 29.4);

14

(c)                                  alter or add to the Memorandum with respect to any objects, powers or other matters specified therein; and

(d)                                 reduce its share capital or any capital redemption reserve fund.

19                                  Offices and Places of Business

Subject to the provisions of the Statute, the Company may by resolution of the Directors change the location of its Registered Office. The Company may, in addition to its Registered Office, maintain such other offices or places of business as the Directors determine.

20                                  General Meetings

20.1                        All general meetings other than annual general meetings shall be called extraordinary general meetings.

20.2                        The Company may, but shall not (unless required by the Statute) be obliged to, in each year hold a general meeting as its annual general meeting, and shall specify the meeting as such in the notices calling it.  Any annual general meeting shall be held at such time and place as the Directors shall appoint and if no other time and place is prescribed by them, it shall be held at the Registered Office on the second Wednesday in December of each year at ten o’clock in the morning.  At these meetings the report of the Directors (if any) shall be presented.

20.3                        The Directors, the chief executive officer or the chairman of the board of Directors may call general meetings, and they shall on a Members’ requisition forthwith proceed to convene an extraordinary general meeting of the Company.

20.4                        A Members’ requisition is a requisition of Members holding at the date of deposit of the requisition not less than ten per cent. in par value of the issued Shares which as at that date carry the right to vote at general meetings of the Company.

20.5                        The Members’ requisition must state the objects of the meeting and must be signed by the requisitionists and deposited at the Registered Office, and may consist of several documents in like form each signed by one or more requisitionists.

20.6                        If there are no Directors as at the date of the deposit of the Members’ requisition or if the Directors do not within twenty-one days from the date of the deposit of the Members’ requisition duly proceed to convene a general meeting to be held within a further twenty-one days, the requisitionists, or any of them representing more than one-half of the total voting rights of all of the requisitionists, may themselves convene a general meeting, but any meeting so convened shall be held no later than the day which falls three months after the expiration of the said twenty-one day period.

20.7                        A general meeting convened as aforesaid by requisitionists shall be convened in the same manner as nearly as possible as that in which general meetings are to be convened by Directors.

20.8                        Members seeking to bring business before the annual general meeting or to nominate candidates for election as directors at the annual general meeting must deliver notice to the principal

15

executive offices of the Company not later than the close of business on the ninetieth day nor earlier than the close of business on the one hundred and twentieth day prior to the scheduled date of the annual general meeting.

21                                  Notice of General Meetings

21.1                        At least five clear days’ notice shall be given of any general meeting.  Every notice shall specify the place, the day and the hour of the meeting and the general nature of the business to be conducted at the general meeting and shall be given in the manner hereinafter mentioned or in such other manner if any as may be prescribed by the Company, provided that a general meeting of the Company shall, whether or not the notice specified in this Article has been given and whether or not the provisions of the Articles regarding general meetings have been complied with, be deemed to have been duly convened if it is so agreed:

(a)                                 in the case of an annual general meeting, by all of the Members entitled to attend and vote thereat; and

(b)                                 in the case of an extraordinary general meeting, by a majority in number of the Members having a right to attend and vote at the meeting, together holding not less than ninety-five per cent. in par value of the Shares giving that right.

21.2                        The accidental omission to give notice of a general meeting to, or the non receipt of notice of a general meeting by, any person entitled to receive such notice shall not invalidate the proceedings of that general meeting.

22                                  Proceedings at General Meetings

22.1                        No business shall be transacted at any general meeting unless a quorum is present. The holders of a majority of the Shares being individuals present in person or by proxy or if a corporation or other non-natural person by its duly authorised representative or proxy shall be a quorum.

22.2                        A person may participate at a general meeting by conference telephone or other communications equipment by means of which all the persons participating in the meeting can communicate with each other.  Participation by a person in a general meeting in this manner is treated as presence in person at that meeting.

22.3                        A resolution (including a Special Resolution) in writing (in one or more counterparts) signed by or on behalf of all of the Members for the time being entitled to receive notice of and to attend and vote at general meetings (or, being corporations or other non-natural persons, signed by their duly authorised representatives) shall be as valid and effective as if the resolution had been passed at a general meeting of the Company duly convened and held.

22.4                        If a quorum is not present within half an hour from the time appointed for the meeting to commence or if during such a meeting a quorum ceases to be present, the meeting, if convened upon a Members’ requisition, shall be dissolved and in any other case it shall stand adjourned to the same day in the next week at the same time and/or place or to such other day, time and/or place as the Directors may determine, and if at the adjourned meeting a quorum is not present

16

within half an hour from the time appointed for the meeting to commence, the Members present shall be a quorum.

22.5                        The Directors may, at any time prior to the time appointed for the meeting to commence, appoint any person to act as chairman of a general meeting of the Company or, if the Directors do not make any such appointment, the chairman, if any, of the board of Directors shall preside as chairman at such general meeting. If there is no such chairman, or if he shall not be present within fifteen minutes after the time appointed for the meeting to commence, or is unwilling to act, the Directors present shall elect one of their number to be chairman of the meeting.

22.6                        If no Director is willing to act as chairman or if no Director is present within fifteen minutes after the time appointed for the meeting to commence, the Members present shall choose one of their number to be chairman of the meeting.

22.7                        The chairman may, with the consent of a meeting at which a quorum is present (and shall if so directed by the meeting) adjourn the meeting from time to time and from place to place, but no business shall be transacted at any adjourned meeting other than the business left unfinished at the meeting from which the adjournment took place.

22.8                        When a general meeting is adjourned for thirty days or more, notice of the adjourned meeting shall be given as in the case of an original meeting.  Otherwise it shall not be necessary to give any such notice of an adjourned meeting.

22.9                        A resolution put to the vote of the meeting shall be decided on a poll.

22.10                 A poll shall be taken as the chairman directs, and the result of the poll shall be deemed to be the resolution of the general meeting at which the poll was demanded.

22.11                 A poll demanded on the election of a chairman or on a question of adjournment shall be taken forthwith.  A poll demanded on any other question shall be taken at such date, time and place as the chairman of the general meeting directs, and any business other than that upon which a poll has been demanded or is contingent thereon may proceed pending the taking of the poll.

22.12                 In the case of an equality of votes the chairman shall be entitled to a second or casting vote.

23                                  Votes of Members

23.1                        Subject to any rights or restrictions attached to any Shares, including as set out at Article 29.4, every Member present in any such manner shall have one vote for every Share of which he is the holder.

23.2                        In the case of joint holders the vote of the senior holder who tenders a vote, whether in person or by proxy (or, in the case of a corporation or other non-natural person, by its duly authorised representative or proxy), shall be accepted to the exclusion of the votes of the other joint holders, and seniority shall be determined by the order in which the names of the holders stand in the Register of Members.

17

23.3                        A Member of unsound mind, or in respect of whom an order has been made by any court, having jurisdiction in lunacy, may vote by his committee, receiver, curator bonis, or other person on such Member’s behalf appointed by that court, and any such committee, receiver, curator bonis or other person may vote by proxy.

23.4                        No person shall be entitled to vote at any general meeting unless he is registered as a Member on the record date for such meeting nor unless all calls or other monies then payable by him in respect of Shares have been paid.

23.5                        No objection shall be raised as to the qualification of any voter except at the general meeting or adjourned general meeting at which the vote objected to is given or tendered and every vote not disallowed at the meeting shall be valid.  Any objection made in due time in accordance with this Article shall be referred to the chairman whose decision shall be final and conclusive.

23.6                        Votes may be cast either personally or by proxy (or in the case of a corporation or other non-natural person by its duly authorised representative or proxy). A Member may appoint more than one proxy or the same proxy under one or more instruments to attend and vote at a meeting. Where a Member appoints more than one proxy the instrument of proxy shall specify the number of Shares in respect of which each proxy is entitled to exercise the related votes.

23.7                        A Member holding more than one Share need not cast the votes in respect of his Shares in the same way on any resolution and therefore may vote a Share or some or all such Shares either for or against a resolution and/or abstain from voting a Share or some or all of the Shares and, subject to the terms of the instrument appointing him, a proxy appointed under one or more instruments may vote a Share or some or all of the Shares in respect of which he is appointed either for or against a resolution and/or abstain from voting a Share or some or all of the Shares in respect of which he is appointed.

24                                  Proxies

24.1                        The instrument appointing a proxy shall be in writing and shall be executed under the hand of the appointor or of his attorney duly authorised in writing, or, if the appointor is a corporation or other non natural person, under the hand of its duly authorised representative.  A proxy need not be a Member.

24.2                        The Directors may, in the notice convening any meeting or adjourned meeting, or in an instrument of proxy sent out by the Company, specify the manner by which the instrument appointing a proxy shall be deposited and the place and the time (being not later than the time appointed for the commencement of the meeting or adjourned meeting to which the proxy relates) at which the instrument appointing a proxy shall be deposited.  In the absence of any such direction from the Directors in the notice convening any meeting or adjourned meeting or in an instrument of proxy sent out by the Company, the instrument appointing a proxy shall be deposited physically at the Registered Office not less than forty-eight hours before the time appointed for the meeting or adjourned meeting to commence at which the person named in the instrument proposes to vote.

18

24.3                        The chairman may in any event at his discretion declare that an instrument of proxy shall be deemed to have been duly deposited.  An instrument of proxy that is not deposited in the manner permitted, or which has not been declared to have been duly deposited by the chairman, shall be invalid.

24.4                        The instrument appointing a proxy may be in any usual or common form (or such other form as the Directors may approve) and may be expressed to be for a particular meeting or any adjournment thereof or generally until revoked.  An instrument appointing a proxy shall be deemed to include the power to demand or join or concur in demanding a poll.

24.5                        Votes given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal or revocation of the proxy or of the authority under which the proxy was executed, or the transfer of the Share in respect of which the proxy is given unless notice in writing of such death, insanity, revocation or transfer was received by the Company at the Registered Office before the commencement of the general meeting, or adjourned meeting at which it is sought to use the proxy.

25                                  Corporate Members

25.1                        Any corporation or other non-natural person which is a Member may in accordance with its constitutional documents, or in the absence of such provision by resolution of its directors or other governing body, authorise such person as it thinks fit to act as its representative at any meeting of the Company or of any class of Members, and the person so authorised shall be entitled to exercise the same powers on behalf of the corporation which he represents as the corporation could exercise if it were an individual Member.

25.2                        If a clearing house (or its nominee(s)), being a corporation, is a Member, it may authorise such persons as it sees fit to act as its representative at any meeting of the Company or at any meeting of any class of Members provided that the authorisation shall specify the number and class of Shares in respect of which each such representative is so authorised. Each person so authorised under the provisions of this Article shall be deemed to have been duly authorised without further evidence of the facts and be entitled to exercise the same rights and powers on behalf of the clearing house (or its nominee(s)) as if such person was the registered holder of such Shares held by the clearing house (or its nominee(s)).

26                                  Shares that May Not be Voted

Shares in the Company that are beneficially owned by the Company shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding Shares at any given time.

27                                  Directors

There shall be a board of Directors consisting of not less than one person provided however that the Company may by Ordinary Resolution increase or reduce the limits in the number of Directors.

19

28                                  Powers of Directors

28.1                        Subject to the provisions of the Statute, the Memorandum and the Articles and to any directions given by Special Resolution, the business of the Company shall be managed by the Directors who may exercise all the powers of the Company.  No alteration of the Memorandum or Articles and no such direction shall invalidate any prior act of the Directors which would have been valid if that alteration had not been made or that direction had not been given.  A duly convened meeting of Directors at which a quorum is present may exercise all powers exercisable by the Directors.

28.2                        All cheques, promissory notes, drafts, bills of exchange and other negotiable or transferable instruments and all receipts for monies paid to the Company shall be signed, drawn, accepted, endorsed or otherwise executed as the case may be in such manner as the Directors shall determine by resolution.

28.3                        The Directors on behalf of the Company may pay a gratuity or pension or allowance on retirement to any Director who has held any other salaried office or place of profit with the Company or to his widow or dependants and may make contributions to any fund and pay premiums for the purchase or provision of any such gratuity, pension or allowance.

28.4                        The Directors may exercise all the powers of the Company to borrow money and to mortgage or charge its undertaking, property and assets (present and future) and uncalled capital or any part thereof and to issue debentures, debenture stock, mortgages, bonds and other such securities whether outright or as security for any debt, liability or obligation of the Company or of any third party.

29                                  Appointment and Removal of Directors

29.1                        Prior to the closing of a Business Combination, the Company may by Ordinary Resolution of the holders of the Class B Shares appoint any person to be a Director or may by Ordinary Resolution remove any Director.  For the avoidance of doubt, prior to the closing of a Business Combination holders of Class A Shares shall have no right to vote on the appointment or removal of any Director.

29.2                        The Directors may appoint any person to be a Director, either to fill a vacancy or as an additional Director provided that the appointment does not cause the number of Directors to exceed any number fixed by or in accordance with the Articles as the maximum number of Directors.

29.3                        After the closing of a Business Combination, the Company may by Ordinary Resolution appoint any person to be a Director or may by Ordinary Resolution remove any Director.

29.4                        Article 29.1 may only be amended by a Special Resolution passed by a majority of at least 90% of such Members as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at a general meeting of which notice specifying the intention to propose the resolution as a special resolution has been given, or by way of unanimous written resolution of all Members.

30                                  Vacation of Office of Director

The office of a Director shall be vacated if:

20

(a)                                 the Director gives notice in writing to the Company that he resigns the office of Director; or

(b)                                 the Director absents himself (for the avoidance of doubt, without being represented by proxy) from three consecutive meetings of the board of Directors without special leave of absence from the Directors, and the Directors pass a resolution that he has by reason of such absence vacated office; or

(c)                                  the Director dies, becomes bankrupt or makes any arrangement or composition with his creditors generally; or

(d)                                 the Director is found to be or becomes of unsound mind; or

(e)                                  all of the other Directors (being not less than two in number) determine that he should be removed as a Director, either by a resolution passed by all of the other Directors at a meeting of the Directors duly convened and held in accordance with the Articles or by a resolution in writing signed by all of the other Directors.

31                                  Proceedings of Directors

31.1                        The quorum for the transaction of the business of the Directors may be fixed by the Directors, and unless so fixed shall be two if there are two or more Directors, and shall be one if there is only one Director.

31.2                        Subject to the provisions of the Articles, the Directors may regulate their proceedings as they think fit.  Questions arising at any meeting shall be decided by a majority of votes.  In the case of an equality of votes, the chairman shall have a second or casting vote.

31.3                        A person may participate in a meeting of the Directors or committee of Directors by conference telephone or other communications equipment by means of which all the persons participating in the meeting can communicate with each other at the same time. Participation by a person in a meeting in this manner is treated as presence in person at that meeting.  Unless otherwise determined by the Directors, the meeting shall be deemed to be held at the place where the chairman is located at the start of the meeting.

31.4                        A resolution in writing (in one or more counterparts) signed by all the Directors or all the members of a committee of the Directors or, in the case of a resolution in writing relating to the removal of any Director or the vacation of office by any Director, all of the Directors other than the Director who is the subject of such resolution shall be as valid and effectual as if it had been passed at a meeting of the Directors, or committee of Directors as the case may be, duly convened and held.

31.5                        A Director may, or other officer of the Company on the direction of a Director shall, call a meeting of the Directors by at least two days’ notice in writing to every Director which notice shall set forth the general nature of the business to be considered unless notice is waived by all the Directors either at, before or after the meeting is held. To any such notice of a meeting of the Directors all the provisions of the Articles relating to the giving of notices by the Company to the Members shall apply mutatis mutandis.

21

31.6                        The continuing Directors (or a sole continuing Director, as the case may be) may act notwithstanding any vacancy in their body, but if and so long as their number is reduced below the number fixed by or pursuant to the Articles as the necessary quorum of Directors the continuing Directors or Director may act for the purpose of increasing the number of Directors to be equal to such fixed number, or of summoning a general meeting of the Company, but for no other purpose.

31.7                        The Directors may elect a chairman of their board and determine the period for which he is to hold office; but if no such chairman is elected, or if at any meeting the chairman is not present within five minutes after the time appointed for the meeting to commence, the Directors present may choose one of their number to be chairman of the meeting.

31.8                        All acts done by any meeting of the Directors or of a committee of the Directors shall, notwithstanding that it is afterwards discovered that there was some defect in the appointment of any Director, and/or that they or any of them were disqualified, and/or had vacated their office and/or were not entitled to vote, be as valid as if every such person had been duly appointed and/or not disqualified to be a Director and/or had not vacated their office and/or had been entitled to vote, as the case may be.

31.9                        A Director may be represented at any meetings of the board of Directors by a proxy appointed in writing by him.  The proxy shall count towards the quorum and the vote of the proxy shall for all purposes be deemed to be that of the appointing Director.

32                                  Presumption of Assent

A Director who is present at a meeting of the board of Directors at which action on any Company matter is taken shall be presumed to have assented to the action taken unless his dissent shall be entered in the minutes of the meeting or unless he shall file his written dissent from such action with the person acting as the chairman or secretary of the meeting before the adjournment thereof or shall forward such dissent by registered post to such person immediately after the adjournment of the meeting.  Such right to dissent shall not apply to a Director who voted in favour of such action.

33                                  Directors’ Interests

33.1                        A Director may hold any other office or place of profit under the Company (other than the office of Auditor) in conjunction with his office of Director for such period and on such terms as to remuneration and otherwise as the Directors may determine.

33.2                        A Director may act by himself or by, through or on behalf of his firm in a professional capacity for the Company and he or his firm shall be entitled to remuneration for professional services as if he were not a Director.

33.3                        A Director may be or become a director or other officer of or otherwise interested in any company promoted by the Company or in which the Company may be interested as a shareholder, a contracting party or otherwise, and no such Director shall be accountable to the Company for any remuneration or other benefits received by him as a director or officer of, or from his interest in, such other company.

22

33.4                        No person shall be disqualified from the office of Director or prevented by such office from contracting with the Company, either as vendor, purchaser or otherwise, nor shall any such contract or any contract or transaction entered into by or on behalf of the Company in which any Director shall be in any way interested be or be liable to be avoided, nor shall any Director so contracting or being so interested be liable to account to the Company for any profit realised by or arising in connection with any such contract or transaction by reason of such Director or alternate Director holding office or of the fiduciary relationship thereby established.  A Director shall be at liberty to vote in respect of any contract or transaction in which he is interested provided that the nature of the interest of any Director in any such contract or transaction shall be disclosed by him at or prior to its consideration and any vote thereon.

33.5                        A general notice that a Director is a shareholder, director, officer or employee of any specified firm or company and is to be regarded as interested in any transaction with such firm or company shall be sufficient disclosure for the purposes of voting on a resolution in respect of a contract or transaction in which he has an interest, and after such general notice it shall not be necessary to give special notice relating to any particular transaction.

34                                  Minutes

The Directors shall cause minutes to be made in books kept for the purpose of all appointments of officers made by the Directors, all proceedings at meetings of the Company or the holders of any class of Shares and of the Directors, and of committees of the Directors, including the names of the Directors present at each meeting.

35                                  Delegation of Directors’ Powers

35.1                        The Directors may delegate any of their powers, authorities and discretions, including the power to sub-delegate, to any committee consisting of one or more Directors. Any such delegation may be made subject to any conditions the Directors may impose and either collaterally with or to the exclusion of their own powers and any such delegation may be revoked or altered by the Directors.  Subject to any such conditions, the proceedings of a committee of Directors shall be governed by the Articles regulating the proceedings of Directors, so far as they are capable of applying.

35.2                        The Directors may establish any committees, local boards or agencies or appoint any person to be a manager or agent for managing the affairs of the Company and may appoint any person to be a member of such committees, local boards or agencies.  Any such appointment may be made subject to any conditions the Directors may impose, and either collaterally with or to the exclusion of their own powers and any such appointment may be revoked or altered by the Directors.  Subject to any such conditions, the proceedings of any such committee, local board or agency shall be governed by the Articles regulating the proceedings of Directors, so far as they are capable of applying.

35.3                        The Directors may by power of attorney or otherwise appoint any person to be the agent of the Company on such conditions as the Directors may determine, provided that the delegation is not to the exclusion of their own powers and may be revoked by the Directors at any time.

23

35.4                        The Directors may by power of attorney or otherwise appoint any company, firm, person or body of persons, whether nominated directly or indirectly by the Directors, to be the attorney or authorised signatory of the Company for such purpose and with such powers, authorities and discretions (not exceeding those vested in or exercisable by the Directors under the Articles) and for such period and subject to such conditions as they may think fit, and any such powers of attorney or other appointment may contain such provisions for the protection and convenience of persons dealing with any such attorneys or authorised signatories as the Directors may think fit and may also authorise any such attorney or authorised signatory to delegate all or any of the powers, authorities and discretions vested in him.

35.5                        The Directors may appoint such officers of the Company (including, for the avoidance of doubt and without limitation, any chairman of the board of Directors, chief executive officer, president, chief financial officer, vice-presidents, secretary, assistant secretary, treasurer or any other officers as may be determined by the Directors) as they consider necessary on such terms, at such remuneration and to perform such duties, and subject to such provisions as to disqualification and removal as the Directors may think fit.  Unless otherwise specified in the terms of his appointment an officer of the Company may be removed by resolution of the Directors or Members. An officer of the Company may vacate his office at any time if he gives notice in writing to the Company that he resigns his office.

36                                  No Minimum Shareholding

The Company in general meeting may fix a minimum shareholding required to be held by a Director, but unless and until such a shareholding qualification is fixed a Director is not required to hold Shares.

37                                  Remuneration of Directors

37.1                        The remuneration to be paid to the Directors, if any, shall be such remuneration as the Directors shall determine, provided that no remuneration shall be paid to any Director prior to the consummation of a Business Combination.  The Directors shall also, whether prior to or after the consummation of a Business Combination, be entitled to be paid all travelling, hotel and other expenses properly incurred by them in connection with their attendance at meetings of Directors or committees of Directors, or general meetings of the Company, or separate meetings of the holders of any class of Shares or debentures of the Company, or otherwise in connection with the business of the Company or the discharge of their duties as a Director, or to receive a fixed allowance in respect thereof as may be determined by the Directors, or a combination partly of one such method and partly the other.

37.2                        The Directors may by resolution approve additional remuneration to any Director for any services which in the opinion of the Directors go beyond his ordinary routine work as a Director.  Any fees paid to a Director who is also counsel, attorney or solicitor to the Company, or otherwise serves it in a professional capacity shall be in addition to his remuneration as a Director.

38                                  Seal

38.1                        The Company may, if the Directors so determine, have a Seal. The Seal shall only be used by the authority of the Directors or of a committee of the Directors authorised by the Directors.  Every

24

instrument to which the Seal has been affixed shall be signed by at least one person who shall be either a Director or some officer of the Company or other person appointed by the Directors for the purpose.

38.2                        The Company may have for use in any place or places outside the Cayman Islands a duplicate Seal or Seals each of which shall be a facsimile of the common Seal of the Company and, if the Directors so determine, with the addition on its face of the name of every place where it is to be used.

38.3                        A Director or officer, representative or attorney of the Company may without further authority of the Directors affix the Seal over his signature alone to any document of the Company required to be authenticated by him under seal or to be filed with the Registrar of Companies in the Cayman Islands or elsewhere wheresoever.

39                                  Dividends, Distributions and Reserve

39.1                        Subject to the Statute and this Article and except as otherwise provided by the rights attached to any Shares, the Directors may resolve to pay Dividends and other distributions on Shares in issue and authorise payment of the Dividends or other distributions out of the funds of the Company lawfully available therefor.  A Dividend shall be deemed to be an interim Dividend unless the terms of the resolution pursuant to which the Directors resolve to pay such Dividend specifically state that such Dividend shall be a final Dividend. No Dividend or other distribution shall be paid except out of the realised or unrealised profits of the Company, out of the share premium account or as otherwise permitted by law.

39.2                        Except as otherwise provided by the rights attached to any Shares, all Dividends and other distributions shall be paid according to the par value of the Shares that a Member holds. If any Share is issued on terms providing that it shall rank for Dividend as from a particular date, that Share shall rank for Dividend accordingly.

39.3                        The Directors may deduct from any Dividend or other distribution payable to any Member all sums of money (if any) then payable by him to the Company on account of calls or otherwise.

39.4                        The Directors may resolve that any Dividend or other distribution be paid wholly or partly by the distribution of specific assets and in particular (but without limitation) by the distribution of shares, debentures, or securities of any other company or in any one or more of such ways and where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional Shares and may fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any Members upon the basis of the value so fixed in order to adjust the rights of all Members and may vest any such specific assets in trustees in such manner as may seem expedient to the Directors.

39.5                        Except as otherwise provided by the rights attached to any Shares, Dividends and other distributions may be paid in any currency. The Directors may determine the basis of conversion for any currency conversions that may be required and how any costs involved are to be met.

25

39.6                        The Directors may, before resolving to pay any Dividend or other distribution, set aside such sums as they think proper as a reserve or reserves which shall, at the discretion of the Directors, be applicable for any purpose of the Company and pending such application may, at the discretion of the Directors, be employed in the business of the Company.

39.7                        Any Dividend, other distribution, interest or other monies payable in cash in respect of Shares may be paid by wire transfer to the holder or by cheque or warrant sent through the post directed to the registered address of the holder or, in the case of joint holders, to the registered address of the holder who is first named on the Register of Members or to such person and to such address as such holder or joint holders may in writing direct.  Every such cheque or warrant shall be made payable to the order of the person to whom it is sent.  Any one of two or more joint holders may give effectual receipts for any Dividends, other distributions, bonuses, or other monies payable in respect of the Share held by them as joint holders.

39.8                        No Dividend or other distribution shall bear interest against the Company.

39.9                        Any Dividend or other distribution which cannot be paid to a Member and/or which remains unclaimed after six months from the date on which such Dividend or other distribution becomes payable may, in the discretion of the Directors, be paid into a separate account in the Company’s name, provided that the Company shall not be constituted as a trustee in respect of that account and the Dividend or other distribution shall remain as a debt due to the Member.  Any Dividend or other distribution which remains unclaimed after a period of six years from the date on which such Dividend or other distribution becomes payable shall be forfeited and shall revert to the Company.

40                                  Capitalisation

The Directors may at any time capitalise any sum standing to the credit of any of the Company’s reserve accounts or funds (including the share premium account and capital redemption reserve fund) or any sum standing to the credit of the profit and loss account or otherwise available for distribution; appropriate such sum to Members in the proportions in which such sum would have been divisible amongst such Members had the same been a distribution of profits by way of Dividend or other distribution; and apply such sum on their behalf in paying up in full unissued Shares for allotment and distribution credited as fully paid-up to and amongst them in the proportion aforesaid.  In such event the Directors shall do all acts and things required to give effect to such capitalisation, with full power given to the Directors to make such provisions as they think fit in the case of Shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned).  The Directors may authorise any person to enter on behalf of all of the Members interested into an agreement with the Company providing for such capitalisation and matters incidental or relating thereto and any agreement made under such authority shall be effective and binding on all such Members and the Company.

41                                  Books of Account

41.1                        The Directors shall cause proper books of account to be kept with respect to all sums of money received and expended by the Company and the matters in respect of which the receipt or expenditure takes place, all sales and purchases of goods by the Company and the assets and

26

liabilities of the Company.  Proper books of account shall not be deemed to be kept if there are not kept such books of account as are necessary to give a true and fair view of the state of the Company’s affairs and to explain its transactions.

41.2                        The Directors shall determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of Members not being Directors and no Member (not being a Director) shall have any right of inspecting any account or book or document of the Company except as conferred by Statute or authorised by the Directors or by the Company in general meeting.

41.3                        The Directors may cause to be prepared and to be laid before the Company in general meeting profit and loss accounts, balance sheets, group accounts (if any) and such other reports and accounts as may be required by law.

42                                  Audit

42.1                        The Directors may appoint an Auditor of the Company who shall hold office on such terms as the Directors determine.

42.2                        Without prejudice to the freedom of the Directors to establish any other committee, if the Shares (or depositary receipts therefor) are listed or quoted on the Designated Stock Exchange, and if required by the Designated Stock Exchange, the Directors shall establish and maintain an Audit Committee as a committee of the board of Directors and shall adopt a formal written Audit Committee charter and review and assess the adequacy of the formal written charter on an annual basis.  The composition and responsibilities of the Audit Committee shall comply with the rules and regulations of the SEC and the Designated Stock Exchange. The Audit Committee shall meet at least once every financial quarter, or more frequently as circumstances dictate.

42.3                        If the Shares (or depositary receipts therefor) are listed or quoted on the Designated Stock Exchange, the Company shall conduct an appropriate review of all related party transactions on an ongoing basis and shall utilise the Audit Committee for the review and approval of potential conflicts of interest.

42.4                        The remuneration of the Auditor shall be fixed by the Audit Committee (if one exists).

42.5                        If the office of Auditor becomes vacant by resignation or death of the Auditor, or by his becoming incapable of acting by reason of illness or other disability at a time when his services are required, the Directors shall fill the vacancy and determine the remuneration of such Auditor.

42.6                        Every Auditor of the Company shall have a right of access at all times to the books and accounts and vouchers of the Company and shall be entitled to require from the Directors and officers of the Company such information and explanation as may be necessary for the performance of the duties of the Auditor.

42.7                        Auditors shall, if so required by the Directors, make a report on the accounts of the Company during their tenure of office at the next annual general meeting following their appointment in the

27

case of a company which is registered with the Registrar of Companies as an ordinary company, and at the next extraordinary general meeting following their appointment in the case of a company which is registered with the Registrar of Companies as an exempted company, and at any other time during their term of office, upon request of the Directors or any general meeting of the Members.

43                                  Notices

43.1                        Notices shall be in writing and may be given by the Company to any Member either personally or by sending it by courier, post, cable, telex, fax or e-mail to him or to his address as shown in the Register of Members (or where the notice is given by e-mail by sending it to the e-mail address provided by such Member).  Notice may also be served in accordance with the requirements of the Designated Stock Exchange.

43.2                        Where a notice is sent by courier, service of the notice shall be deemed to be effected by delivery of the notice to a courier company, and shall be deemed to have been received on the third day (not including Saturdays or Sundays or public holidays) following the day on which the notice was delivered to the courier.  Where a notice is sent by post, service of the notice shall be deemed to be effected by properly addressing, pre paying and posting a letter containing the notice, and shall be deemed to have been received on the fifth day (not including Saturdays or Sundays or public holidays in the Cayman Islands) following the day on which the notice was posted.  Where a notice is sent by cable, telex or fax, service of the notice shall be deemed to be effected by properly addressing and sending such notice and shall be deemed to have been received on the same day that it was transmitted.  Where a notice is given by e-mail, service of the notice shall be deemed to be effected by transmitting the e-mail to the e-mail address provided by the intended recipient and shall be deemed to have been received on the same day that it was sent, and it shall not be necessary for the receipt of the e-mail to be acknowledged by the recipient.

43.3                        A notice may be given by the Company to the person or persons which the Company has been advised are entitled to a Share or Shares in consequence of the death or bankruptcy of a Member in the same manner as other notices which are required to be given under the Articles and shall be addressed to them by name, or by the title of representatives of the deceased, or trustee of the bankrupt, or by any like description at the address supplied for that purpose by the persons claiming to be so entitled, or at the option of the Company by giving the notice in any manner in which the same might have been given if the death or bankruptcy had not occurred.

43.4                        Notice of every general meeting shall be given in any manner authorised by the Articles to every holder of Shares carrying an entitlement to receive such notice on the record date for such meeting except that in the case of joint holders the notice shall be sufficient if given to the joint holder first named in the Register of Members and every person upon whom the ownership of a Share devolves by reason of his being a legal personal representative or a trustee in bankruptcy of a Member where the Member but for his death or bankruptcy would be entitled to receive notice of the meeting, and no other person shall be entitled to receive notices of general meetings.

28

44                                  Winding Up

44.1                        If the Company shall be wound up, the liquidator shall apply the assets of the Company in satisfaction of creditors’ claims in such manner and order as such liquidator thinks fit. Subject to the rights attaching to any Shares, in a winding up:

(a)                                 if the assets available for distribution amongst the Members shall be insufficient to repay the whole of the Company’s issued share capital, such assets shall be distributed so that, as nearly as may be, the losses shall be borne by the Members in proportion to the par value of the Shares held by them; or

(b)                                 if the assets available for distribution amongst the Members shall be more than sufficient to repay the whole of the Company’s issued share capital at the commencement of the winding up, the surplus shall be distributed amongst the Members in proportion to the par value of the Shares held by them at the commencement of the winding up subject to a deduction from those Shares in respect of which there are monies due, of all monies payable to the Company for unpaid calls or otherwise.

44.2                        If the Company shall be wound up, the liquidator may, subject to the rights attaching to any Shares and with the sanction of a Special Resolution of the Company and any other sanction required by the Statute, divide amongst the Members in kind the whole or any part of the assets of the Company (whether such assets shall consist of property of the same kind or not) and may for that purpose value any assets and determine how the division shall be carried out as between the Members or different classes of Members.  The liquidator may, with the like sanction, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the Members as the liquidator, with the like sanction, shall think fit, but so that no Member shall be compelled to accept any asset upon which there is a liability.

45                                  Indemnity and Insurance

45.1                        Every Director and officer of the Company (which for the avoidance of doubt, shall not include auditors of the Company), together with every former Director and former officer of the Company (each an “Indemnified Person”) shall be indemnified out of the assets of the Company against any liability, action, proceeding, claim, demand, costs, damages or expenses, including legal expenses, whatsoever which they or any of them may incur as a result of any act or failure to act in carrying out their functions other than such liability (if any) that they may incur by reason of their own actual fraud, wilful neglect or wilful default.  No Indemnified Person shall be liable to the Company for any loss or damage incurred by the Company as a result (whether direct or indirect) of the carrying out of their functions unless that liability arises through the actual fraud, wilful neglect or wilful default of such Indemnified Person.  No person shall be found to have committed actual fraud, wilful neglect or wilful default under this Article unless or until a court of competent jurisdiction shall have made a finding to that effect.

45.2                        The Company shall advance to each Indemnified Person reasonable attorneys’ fees and other costs and expenses incurred in connection with the defence of any action, suit, proceeding or investigation involving such Indemnified Person for which indemnity will or could be sought.  In connection with any advance of any expenses hereunder, the Indemnified Person shall execute

29

an undertaking to repay the advanced amount to the Company if it shall be determined by final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification pursuant to this Article.  If it shall be determined by a final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification with respect to such judgment, costs or expenses, then such party shall not be indemnified with respect to such judgment, costs or expenses and any advancement shall be returned to the Company (without interest) by the Indemnified Person.

45.3                        The Directors, on behalf of the Company, may purchase and maintain insurance for the benefit of any Director or other officer of the Company against any liability which, by virtue of any rule of law, would otherwise attach to such person in respect of any negligence, default, breach of duty or breach of trust of which such person may be guilty in relation to the Company.

46                                  Financial Year

Unless the Directors otherwise prescribe, the financial year of the Company shall end on 31st December in each year and, following the year of incorporation, shall begin on 1st January in each year.

47                                  Transfer by Way of Continuation

If the Company is exempted as defined in the Statute, it shall, subject to the provisions of the Statute and with the approval of a Special Resolution, have the power to register by way of continuation as a body corporate under the laws of any jurisdiction outside the Cayman Islands and to be deregistered in the Cayman Islands.

48                                  Mergers and Consolidations

The Company shall, with the approval of a Special Resolution, have the power to merge or consolidate with one or more constituent companies (as defined in the Statute), upon such terms as the Directors may determine.

49                                  Business Combination

49.1                        Notwithstanding any other provision of these Articles, this Article 49 shall apply during the period commencing upon the adoption of these Articles and terminating upon the first to occur of the consummation of any Business Combination and the distribution of the Trust Fund pursuant to Article 49.4. In the event of a conflict between this Article 49 and any other Articles, the provisions of this Article 49 shall prevail, and Articles 49.1, 49.3 and 49.4 may not be amended prior to the consummation of a Business Combination without a Special Resolution, the approval threshold for which is unanimity (100%) of all Members entitled to vote.

49.2                        Prior to the consummation of any Business Combination, the Company shall either:

(a)                                 submit such Business Combination to its Members for approval; or

(b)                                 provide Members with the opportunity to have their Shares redeemed by means of a tender offer for an amount equal to their pro rata share of the Trust Fund, provided that the Company shall not redeem Shares in an amount that would cause the Company’s net tangible assets to be less than US$5,000,001.

30

The Company shall initiate any tender offer in accordance with Rule 13e-4 and Regulation 14E of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), and shall file tender offer documents with the SEC prior to completing a Business Combination which contain substantially the same financial and other information about such Business Combination and the redemption rights as is required under Regulation 14A of the Exchange Act, to redeem Shares issued in the IPO.

At a meeting called for the purposes of approving a Business Combination pursuant to this Article, in the event that a majority of the Shares voted are voted for the approval of the Business Combination, the Company shall be authorised to consummate the Business Combination, provided that the Company shall not consummate any Business Combination unless the Company has net tangible assets of at least US$5,000,001 upon such consummation or any greater net tangible asset or cash requirement that may be contained in the agreement relating to the Business Combination.

49.3                        Any Member holding Shares issued to persons who are not a Founder, officer or Director may, contemporaneously with any vote on a Business Combination, elect to have their Shares issued in the IPO redeemed for cash (the “IPO Redemption”), provided that no such Member acting together with any affiliate of his or any other person with whom he is acting in concert or as a partnership, syndicate, or other group for the purposes of acquiring, holding, or disposing of Shares may exercise this redemption right with respect to more than fiteen per cent. of the Shares issued in the IPO. If so demanded, the Company shall pay any such redeeming Member, regardless of whether he is voting for or against such proposed Business Combination, a per Share redemption price equal to their pro rata share of the Trust Fund (such redemption price being referred to herein as the “Redemption Price”).

The Redemption Price shall be paid promptly following the consummation of the relevant Business Combination.  If the proposed Business Combination is not approved or completed for any reason then such redemptions shall be cancelled and share certificates (if any) returned to the relevant Members as appropriate.

49.4                        In the event that:

(a)                                 the Company does not consummate a Business Combination by twenty-four months after the closing of the IPO the Company shall: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Shares issued in the IPO, at a per Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Fund including interest earned on the funds held in the Trust Fund and not previously released to the Company to pay its taxes (less up to US$50,000 of interest to pay dissolution expenses), divided by the number of then outstanding Shares issued in the IPO, which redemption will completely extinguish public Members’ rights as Members (including the right to receive further liquidation distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Members and its board of directors, dissolve and liquidate, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

31

(b)                                 the Company’s Members approve an amendment to Article (a) that would affect the substance or timing of the Company’s obligation to redeem the Shares issued in the IPO if the Company did not complete its Business Combination within twenty-four months from closing of the IPO, the Company shall provide the Members holding Shares issued in the IPO with the opportunity to redeem all or a portion of their Shares upon such approval at a per Share price, payable in cash, equal to the aggregate amount of the Trust Fund, including interest earned on the funds held in the Trust Fund and not previously released to the Company to pay its taxes, divided by the number of then outstanding Shares issued in the IPO.

49.5                        A holder of Shares issued in the IPO shall be entitled to receive distributions from the Trust Fund only in the event of an IPO Redemption, a redemption of shares by means of a tender offer pursuant to Article 49.2(b), or a distribution of the Trust Fund pursuant to Article 49.4(a) or (b). In no other circumstance shall a holder of Shares issued in the IPO have any right or interest of any kind in the Trust Fund.

49.6                        After the issue of Shares in the IPO, and prior to the consummation of a Business Combination, the Directors shall not issue additional Shares or any other securities that participate in any manner in the Trust Fund or that vote as a class with Shares issued in the IPO on any Business Combination.

49.7                        The uninterested independent Directors shall approve any transaction or transactions between the Company and any of the following parties:

(a)                                 any Member owning an interest in the voting power of the Company that gives such Member a significant influence over the Company; and

(b)                                 any Director or executive officer of the Company and any affiliate or relative of such Director or executive officer.

49.8                        Any payment made to members of the Audit Committee (if one exists) shall require the review and approval of the Directors, with any Director interested in such payment abstaining from such review and approval.

49.9                        A Director may vote in respect of any Business Combination in which such Director has a conflict of interest with respect to the evaluation of such Business Combination.  Such Director must disclose such interest or conflict to the other Directors.

49.10                 Commencing at the Company’s first annual general meeting, and at each annual general meeting thereafter, Directors elected to succeed those Directors whose terms expire shall be elected for a term of office to expire at the second succeeding annual general meeting after their election. Except as the Statute or other applicable law may otherwise require, in the interim between annual general meetings or extraordinary general meetings called for the election of Directors and/or the removal of one or more Directors and the filling of any vacancy in that connection, additional Directors and any vacancies in the board of Directors, including unfilled vacancies resulting from the removal of Directors for cause, may be filled by the vote of a majority of the remaining Directors then in office, although less than a quorum (as defined in these Articles), or by the sole remaining Director. All Directors shall hold office until the expiration of their respective

32

terms of office and until their successors shall have been elected and qualified. A Director elected to fill a vacancy resulting from the death, resignation or removal of a Director shall serve for the remainder of the full term of the Director whose death, resignation or removal shall have created such vacancy and until his successor shall have been elected and qualified.

49.11                 The Audit Committee shall monitor compliance with the terms of the IPO and, if any non-compliance is identified, the Audit Committee shall be charged with the responsibility to take all action necessary to rectify such non-compliance or otherwise cause compliance with the terms of the IPO.

49.12                 The Company may enter into a Business Combination with a target business that is affiliated with the Sponsor, the Directors or executive officers of the Company.

50                                  Certain Tax Filings

Each Tax Filing Authorised Person, and any such other person, acting alone, as any Director shall designate from time to time, are authorised to file tax forms SS-4, W-8 BEN, W-8 IMY, W-9, 8832 and 2553 and such other similar tax forms as are customary to file with any US state or federal governmental authorities or foreign governmental authorities in connection with the formation, activities and/or elections of the Company and such other tax forms as may be approved from time to time by any Director or officer of the Company.  The Company further ratifies and approves any such filing made by any Tax Filing Authorised Person or such other person prior to the date of this Agreement.

2.1                               Form of Warrant.  Each Warrant shall be issued in registered form only.

2.2                               Effect of Countersignature.  If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3                               Registration.

2.3.1                     Warrant Register.  The Warrant Agent shall maintain books (the “Warrant Register”), for the registration of original issuance and the registration of transfer of the Warrants.  Upon the initial issuance of the Warrants in book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company.  Ownership of beneficial interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such institution, with respect to a Warrant in its account, a “Participant”).

If the Depositary subsequently ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement.  In the event that the Public Warrants are not eligible for, or it is no longer necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Warrants which shall be in the form annexed hereto as Exhibit A.

Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer, Chief Financial Officer, Secretary or other

2

principal officer of the Company.  In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.3.2                     Registered Holder.  Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby, for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2.4                               Detachability of Warrants.  The Ordinary Shares and Public Warrants comprising the Units shall begin separate trading on the 52nd day following the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business (a “Business Day”), then on the immediately succeeding Business Day following such date, or earlier (the “Detachment Date”) with the consent of Credit Suisse Securities (USA) LLC, but in no event shall the Ordinary Shares and the Public Warrants comprising the Units be separately traded until (A) the Company has filed a current report on Form 8-K with the Commission containing an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds received by the Company from the exercise by the underwriters of their right to purchase additional Units in the Offering (the “Over-allotment Option”), if the Over-allotment Option is exercised prior to the filing of the Form 8-K, and (B) the Company issues a press release and files with the Commission a Current Report on Form 8-K announcing when such separate trading shall begin.

2.5                               Private Placement Warrants.  The Private Placement Warrants shall be identical to the Public Warrants, except that so long as they are held by the Sponsor or any of its Permitted Transferees (as defined below) the Private Placement Warrants:  (i) may be exercised for cash or on a “cashless basis,” pursuant to subsection 3.3.1(c) hereof, (ii) may not be transferred, assigned or sold until thirty (30) days after the completion by the Company of an initial Business Combination (as defined below), and (iii) shall not be redeemable by the Company; provided, however, that in the case of (ii), the Private Placement Warrants and any Ordinary Shares issued upon exercise of the Private Placement Warrants may be transferred by the holders thereof:

(a)                                 to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor,

(b)                                 in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization;

(c)                                  in the case of an individual, by virtue of laws of descent and distribution upon death of the individual;

3

(d)                                 in the case of an individual, pursuant to a qualified domestic relations order;

(e)                                  by private sales or by transfers made in connection with the consummation of the Company’s Business Combination at prices no greater than the price at which the shares were originally purchased;

(f)                                   in the event of the Company’s liquidation prior to the Company’s completion of an initial Business Combination;

(g)                                  by virtue of the laws of the Cayman Islands or the Sponsor’s limited memorandum and articles of association upon dissolution of the Sponsor; and

(h)                                 in the event of the Company’s completion of a liquidation, merger, share exchange, reorganization or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, however, that, in the case of clauses (a) through (e), these permitted transferees (the “Permitted Transferees”) must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.

3.                                      Terms and Exercise of Warrants.

3.1                               Warrant Price.  Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number of Ordinary Shares stated therein, at the price of $5.75 per half-share (or $11.50 per whole share), subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1.  The term “Warrant Price” as used in this Agreement shall mean the price per share at which Ordinary Shares may be purchased at the time a Warrant is exercised.  The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than twenty (20) Business Days, provided, that the Company shall provide at least twenty (20) days prior written notice of such reduction to Registered Holders of the Warrants and, provided further that any such reduction shall be identical among all of the Warrants.

3.2                               Duration of Warrants.  A Warrant may be exercised only during the period (the “Exercise Period”) commencing on the later of:  (i) the date that is thirty (30) days after the first date on which the Company completes a merger, share exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company and one or more businesses (a “Business Combination”), or (ii) the date that is twelve (12) months from the date of the closing of the Offering, and terminating at 5:00 p.m., New York City time on the earlier to occur of:  (x) the date that is five (5) years after the date on which the Company completes its initial Business Combination, (y) the liquidation of the Company in accordance with the Company’s amended and restated memorandum and articles of association, as amended from time to time, if the Company fails to complete a Business Combination, or (z) other than with respect to the Private Placement Warrants, the Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration Date”); provided, however, that the exercise of

4

any Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration statement.  Except with respect to the right to receive the Redemption Price (as defined below) (other than with respect to a Private Placement Warrant) in the event of a redemption (as set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant in the event of a redemption) not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date.  The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration Date; provided, that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

3.3                               Exercise of Warrants.

3.3.1                     Payment.  Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may be exercised by the Registered Holder thereof by surrendering it, at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, together with (i) an election to purchase form, duly executed, electing to exercise such Warrants and (ii) payment in full of the Warrant Price for each full Ordinary Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Ordinary Shares and the issuance of such Ordinary Shares, as follows:

(a)                                 in lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent;

(b)                                 in the event of a redemption pursuant to Section 6 hereof in which the Company’s board of directors (the “Board”) has elected to require all holders of the Warrants to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this subsection 3.3.1(b), over the Warrant Price by (y) the Fair Market Value.  Solely for purposes of this subsection 3.3.1(b) and Section 6.3, the “Fair Market Value” shall mean the average last sale price of the Ordinary Shares for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants, pursuant to Section 6  hereof;

(c)                                  with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a Permitted Transferee, by surrendering the Warrants for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this subsection 3.3.1(c), over the Warrant Price by (y) the Fair Market Value.  Solely for purposes of this subsection 3.3.1(c), the “Fair Market Value” shall mean the average last sale price of the Ordinary Shares for the ten (10) trading days ending on the third trading day prior to the date on which notice of exercise of the Warrant is sent to the Warrant Agent; or

5

(d)                                 as provided in Section 7.4 hereof.

3.3.2                     Issuance of Ordinary Shares on Exercise.  As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate, as applicable, for the number of full Ordinary Shares to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares as to which such Warrant shall not have been exercised.  Notwithstanding the foregoing, the Company shall not be obligated to deliver any Ordinary Shares pursuant to the exercise of a Warrant and shall have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the Ordinary Shares underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4.  No Warrant shall be exercisable and the Company shall not be obligated to issue Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise have been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the Registered Holder of the Warrants.  In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Warrant, the holder of such Warrant shall not be entitled to exercise such Warrant and such Warrant may have no value and expire worthless, in which case the purchaser of a Unit containing such Public Warrants shall have paid the full purchase price for the Unit solely for the Ordinary Shares underlying such Unit.  Subject to Section 4.6 of this Agreement, a Registered Holder of Warrants may exercise its Warrants only for a whole number of Ordinary Shares.  The Company may require holders of Public Warrants to settle the Warrant on a “cashless basis” pursuant to Section 7.4.  If, by reason of any exercise of warrants on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in an Ordinary Share, the Company shall round down to the nearest whole number, the number of Ordinary Shares to be issued to such holder.

3.3.3                     Valid Issuance.  All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.3.4                     Date of Issuance.  Each person in whose name any book-entry position or certificate, as applicable, for Ordinary Shares is issued shall for all purposes be deemed to have become the holder of record of such Ordinary Shares on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books or book-entry system are open.

3.3.5                     Maximum Percentage.  A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless

6

he, she or it makes such election.  If the election is made by a holder, the Warrant Agent shall not affect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the Ordinary Shares outstanding immediately after giving effect to such exercise.  For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Ordinary Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein.  Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  For purposes of the Warrant, in determining the number of outstanding Ordinary Shares, the holder may rely on the number of outstanding Ordinary Shares as reflected in (1) the Company’s most recent annual report on Form 10-K, quarterly report on Form 10-Q, current report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of Ordinary Shares outstanding.  For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of Ordinary Shares then outstanding.  In any case, the number of outstanding Ordinary Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of outstanding Ordinary Shares was reported.  By written notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

4.                                      Adjustments.

4.1                               Stock Dividends.

4.1.1                     Split-Ups.  If after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding Ordinary Shares is increased by a capitalization of Ordinary Shares, or by a split-up of Ordinary Shares or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased in proportion to such increase in the outstanding Ordinary Shares.  A rights offering to holders of Ordinary Shares entitling holders to purchase Ordinary Shares at a price less than the “Fair Market Value” (as defined below) shall be deemed a capitalization of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for the Ordinary

7

Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering divided by (y) the Fair Market Value.  For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Ordinary Shares, in determining the price payable for Ordinary Shares, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Fair Market Value” means the volume weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

4.1.2                     Extraordinary Dividends.  If the Company, at any time while the Warrants are outstanding and unexpired, shall pay a dividend or make a distribution in cash, securities or other assets to the holders of Ordinary Shares on account of such Ordinary Shares (or other shares of the Company’s share capital into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders of the Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of the Ordinary Shares in connection with a vote to amend the Company’s amended and restated memorandum and articles of association pursuant to Section 49.1 thereof, (e) as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business Combination is presented to the shareholders of the Company for approval or (f) in connection with the redemption of public shares upon the failure of the Company to complete its initial Business Combination and any subsequent distribution of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”), then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Board, in good faith) of any securities or other assets paid on each Ordinary Share in respect of such Extraordinary Dividend.  For purposes of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Ordinary Shares during the 365-day period ending on the date of declaration of such dividend or distribution (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Ordinary Shares issuable on exercise of each Warrant) does not exceed $0.50 (being 5% of the offering price of the Units in the Offering).

4.2                               Aggregation of Shares.  If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of outstanding Ordinary Shares is decreased by a consolidation, combination, reverse share split or redesignation of Ordinary Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share split, redesignation or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding Ordinary Shares.

4.3                               Adjustments in Exercise Price.  Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which

8

shall be the number of Ordinary Shares purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of Ordinary Shares so purchasable immediately thereafter.

4.4                               Replacement of Securities upon Reorganization, etc.  In case of any redesignation or reorganization of the outstanding Ordinary Shares (other than a change under Section 4.1 or Section 4.2 hereof or that solely affects the par value of such Ordinary Shares), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any redesignation or reorganization of the outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the Ordinary Shares of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or stock or other securities or property (including cash) receivable upon such redesignation, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however, that (i) if the holders of the Ordinary Shares were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the Ordinary Shares in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of the Ordinary Shares (other than a tender, exchange or redemption offer made by the Company in connection with redemption rights held by shareholders of the Company as provided for in the Company’s amended and restated memorandum and articles of association or as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business Combination is presented to the shareholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the outstanding Ordinary Shares, the holder of a Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, securities or other property to which such holder would actually have been entitled as a shareholder if such Warrant holder had exercised the Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Ordinary Shares held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided, further, that if less than 70% of the consideration receivable by the holders of the Ordinary Shares in the applicable event is payable in the form of capital stock or shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an

9

established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Comission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below).  The “Black-Scholes Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (“Bloomberg”).  For purposes of calculating such amount, (1) Section 6 of this Agreement shall be taken into account, (2) the price of each Ordinary Share shall be the volume weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (3) the assumed volatility shall be the 90 day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event, and (4) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Warrant.  “Per Share Consideration” means (i) if the consideration paid to holders of the Ordinary Shares consists exclusively of cash, the amount of such cash per Ordinary Share, and (ii) in all other cases, the volume weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event.  If any reclassification or reorganization also results in a change in Ordinary Shares covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3 and this Section 4.4.  The provisions of this Section 4.4 shall similarly apply to successive redesignations, reorganizations, mergers or consolidations, sales or other transfers.  In no event will the Warrant Price be reduced to less than the par value per share issuable upon exercise of such Warrant.

4.5                               Notices of Changes in Warrant.  Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.  Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event.  Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.6                               No Fractional Shares.  Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon the exercise of Warrants.  If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to such holder.

10

4.7                               Form of Warrant.  The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

4.8                               Other Events.  In case any event shall occur affecting the Company as to which none of the provisions of preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine that an adjustment is necessary, the terms of such adjustment.  The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion.

5.                                      Transfer and Exchange of Warrants.

5.1                               Registration of Transfer.  The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer.  Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent.  The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2                               Procedure for Surrender of Warrants.  Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.

5.3                               Fractional Warrants.  The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

5.4                               Service Charges.  No service charge shall be made for any exchange or registration of transfer of Warrants.

11

5.5                               Warrant Execution and Countersignature.  The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

5.6                               Transfer of Warrants.  Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such Unit.  Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included in such Unit.  Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer of Warrants on and after the Detachment Date.

6.                                      Redemption.

6.1                               Redemption.  Subject to Section 6.4 hereof, not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time while they are exercisable and prior to their expiration, at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.2 below, at the price of $0.01 per Warrant (the “Redemption Price”), provided that the last sales price of the Ordinary Shares reported has been at least $24.00 per share (subject to adjustment in compliance with Section 4  hereof), on each of twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day prior to the date on which notice of the redemption is given and provided that there is an effective registration statement covering the Ordinary Shares issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in Section 6.2 below) or the Company has elected to require the exercise of the Warrants on a “cashless basis” pursuant to subsection 3.3.1.

6.2                               Date Fixed for, and Notice of, Redemption.  In the event that the Company elects to redeem all of the Warrants, the Company shall fix a date for the redemption (the “Redemption Date”).  Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books.  Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice.

6.3                               Exercise After Notice of Redemption.  The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with subsection 3.3.1(b) of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption Date.  In the event that the Company determines to require all holders of Warrants to exercise their Warrants on a “cashless basis” pursuant to subsection 3.3.1, the notice of redemption shall contain the information necessary to calculate the number of Ordinary Shares to be received upon exercise of the Warrants, including the “Fair Market Value” (as such term is defined in subsection 3.3.1(b) hereof) in such case.  On and after

12

the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender of the Warrants, the Redemption Price.

6.4                               Exclusion of Private Placement Warrants.  The Company agrees that the redemption rights provided in this Section 6 shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue to be held by the Sponsor or its Permitted Transferees.  However, once such Private Placement Warrants are transferred (other than to Permitted Transferees under Section 2.5), the Company may redeem the Private Placement Warrants, provided that the criteria for redemption are met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private Placement Warrants prior to redemption pursuant to Section 6.3.  Private Placement Warrants that are transferred to persons other than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public Warrants under this Agreement.

7.                                      Other Provisions Relating to Rights of Holders of Warrants.

7.1                               No Rights as Shareholder.  A Warrant does not entitle the Registered  Holder thereof to any of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as shareholders in respect of the meetings of shareholders or the election of directors of the Company or any other matter.

7.2                               Lost, Stolen, Mutilated, or Destroyed Warrants.  If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed.  Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.

7.3                               Reservation of Ordinary Shares.  The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.4                               Registration of Ordinary Shares; Cashless Exercise at Company’s Option.

7.4.1                     Registration of the Ordinary Shares.  The Company agrees that as soon as practicable, but in no event later than fifteen (15) Business Days after the closing of its initial Business Combination, it shall use its best efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants.  The Company shall use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of this Agreement.  If any such registration statement has not been declared effective by the 60th Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the 61st Business Day after the

13

closing of the Business Combination and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement covering the Ordinary Shares issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act or another exemption) for that number of Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) over the warrant price by (y) the Fair Market Value.  Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume weighted average price of the Ordinary Shares as reported during the ten (10) trading day period ending on the trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary.  The date that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant Agent.  In connection with the “cashless exercise” of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the Ordinary Shares issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall not be required to bear a restrictive legend.  Except as provided in subsection 7.4.2, for the avoidance of any doubt, unless and until all of the Warrants have been exercised, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

7.4.2                     Cashless Exercise at Company’s Option.  If the Ordinary Shares are at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its best efforts to register or qualify for sale the Ordinary Shares issuable upon exercise of the Public Warrant under the blue sky laws of the state of residence of the exercising Public Warrant holder to the extent an exemption is not available.

8.                                      Concerning the Warrant Agent and Other Matters.

8.1                               Payment of Taxes.  The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of Ordinary Shares upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

14

8.2                               Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1                     Appointment of Successor Warrant Agent.  The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company.  If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent.  If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost.  Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority.  After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2                     Notice of Successor Warrant Agent.  In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Ordinary Shares not later than the effective date of any such appointment.

8.2.3                     Merger or Consolidation of Warrant Agent.  Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

8.3                               Fees and Expenses of Warrant Agent.

8.3.1                     Remuneration.  The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2                     Further Assurances.  The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all

15

such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4                               Liability of Warrant Agent.

8.4.1                     Reliance on Company Statement.  Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, the Chief Financial Officer, the Secretary or the Chairman of the Board of the Company and delivered to the Warrant Agent.  The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2                     Indemnity.  The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith.  The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith.

8.4.3                     Exclusions.  The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof).  The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant.  The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Ordinary Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Ordinary Shares shall, when issued, be valid and fully paid and nonassessable.

8.5                               Acceptance of Agency.  The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of Ordinary Shares through the exercise of the Warrants.

8.6                               Waiver.  The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and the Warrant Agent as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.  The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

Warrant Certificate

This Warrant Certificate certifies that                           , or registered assigns, is the registered holder of                            warrant(s) (the “Warrants” and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value (“Ordinary Shares”), of Avista Healthcare Public Acquisition Corp., a Cayman Islands exempted company (the “Company”).  Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and nonassessable Ordinary Shares as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Each Warrant is initially exercisable for one-half of one fully paid and non-assessable Ordinary Share.  The number of Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

The initial Exercise Price per one-half Ordinary Share for any Warrant is equal to $5.75 (or $11.50 per whole share).  A Warrant may not be exercised for a fractional Ordinary Share.  The Exercise Price is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

Subject to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void.

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement.

This Warrant Certificate shall be governed by and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[Form of Warrant Certificate]

[Reverse]

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive                       Ordinary Shares and are issued or to be issued pursuant to a Warrant Agreement dated as of                        , 2016 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder) of the Warrants.  A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company.  Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement.  The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent.  In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Ordinary Shares is current, except through “cashless exercise” as provided for in the Warrant Agreement.

The Warrant Agreement provides that upon the occurrence of certain events the number of Ordinary Shares issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted.  If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares to be issued to the holder of the Warrant.

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.  Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.

Election to Purchase

(To Be Executed Upon Exercise of Warrant)

The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, to receive            Ordinary Shares and herewith tenders payment for such Ordinary Shares to the order of Avista Healthcare Public Acquisition Corp.

In the event that the Warrant has been called for redemption by the Company pursuant to Section 6 of the Warrant Agreement and the Company has required cashless exercise pursuant to Section 6.3 of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.3 of the Warrant Agreement.

In the event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement.

In the event that the Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the Warrant Agreement.

In the event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of Ordinary Shares that this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary Shares.  If said number of shares is less than all of the Ordinary Shares purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the name of                , whose address is                    and that such Warrant Certificate be delivered to                , whose address is                .

Re:                             Initial Public Offering

Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into or proposed to be entered into by and between Avista Healthcare Public Acquisition Corp., a Cayman Islands exempted company (the “Company”), and Credit Suisse Securities (USA) LLC, as the representative of the underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of 34,500,000 of the Company’s units (including up to 4,500,000 units that may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Ordinary Shares”), and one warrant (each, a “Warrant”).  Each Warrant entitles the holder thereof to purchase one-half of one Ordinary Share at a price of $5.75 (or $11.50 per whole share), subject to adjustment.  The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on the Nasdaq Capital Market.  Certain capitalized terms used herein are defined in paragraph 11 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Avista Acquisition Corp., a Cayman Islands exempted company (the “Sponsor”), and the undersigned individuals, each of whom is a director or member of the Company’s management team (each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:

1.                                      The Sponsor and each Insider agrees that if the Company seeks shareholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, it or he shall (i) vote any Shares owned by it or him in favor of any proposed Business Combination and (ii) not redeem any Ordinary Shares owned by it or him in connection with such shareholder approval.

2.                                      The Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 24 months from the closing of the Public Offering, or such later period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Ordinary Shares

sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable and less up to $50,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law.  The Sponsor and each Insider agrees to not propose any amendment to the Company’s amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 24 months from the closing of the Public Offering, unless the Company provides its Public Shareholders with the opportunity to redeem their Ordinary Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Offering Shares.

The Sponsor and each Insider acknowledges that it or he has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it.  The Sponsor and each Insider hereby further waives, with respect to any Ordinary Shares held by it or him, if any, any redemption rights it or he may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares (although the Sponsor and the Insiders shall be entitled to redemption and liquidation rights with respect to any Ordinary Shares it or they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing of the Public Offering).

3.                                      Notwithstanding the provisions set forth in paragraphs 7(a) and (b) below, during the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of Credit Suisse Securities (USA) LLC, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units, Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Shares owned by it, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction, including the filing of a registration statement, specified in clause (i) or (ii).  Each of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver, of the

2

restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver.  Any release or waiver granted shall only be effective two business days after the publication date of such press release.  The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

4.                                      In the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into an acquisition agreement (a “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended.  In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability for such third party claims.  The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

5.                                      To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 4,500,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Initial Shareholders agree that they shall forfeit, on a pro rata basis (but excluding 200,000 Founder Shares held by the Company’s independent directors, which exclusion shall not decrease the total number of Founder Shares subject to forfeiture) at no cost, a number of Founder Shares in the aggregate equal to 1,125,000 multiplied by a fraction, (i) the numerator of which is 4,500,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 4,500,000.  All references in this Letter Agreement to Shares of the Company being forfeited shall take effect as surrenders for no consideration of such Shares as a matter of Cayman Islands law.  The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Initial Shareholders will own an aggregate

3

of 20.0% of the Company’s issued and outstanding Shares after the Public Offering.  The Initial Shareholders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will effect a capitalization or share repurchase or redemption, as applicable, immediately prior to the consummation of the Public offering in such amount as to maintain the ownership of the Initial Shareholders prior to the Public Offering at 20.0% of the Company’s issued and outstanding Shares upon the consummation of the Public Offering.  In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 4,500,000 in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to 1,125,000 in the formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Initial Shareholders would have to return to the Company in order to hold an aggregate of 20.0% of the Company’s issued and outstanding Shares after the Public Offering.

6.                                      (a) The Sponsor and each Insider hereby agrees not to participate in the formation of, or become an officer or director of, any other blank check company until the Company has entered into a definitive agreement regarding its Business Combination or the Company has failed to complete a Business Combination within 24 months after the closing of the Public Offering.  Such restriction does not preclude the Sponsor from pursuing limited partnership interests in asset management companies.

(b)                                 The Sponsor and each Insider hereby agrees and acknowledges that:  (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or Insider of its or his obligations under paragraphs 1, 2, 3, 4, 5, 6(a), 7(a), 7(b), and 9 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to seek injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

7.                                      (a) The Sponsor and each Insider agrees that it or he shall not Transfer (as defined below) any Founder Shares (or Ordinary Shares issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or (B) subsequent to the Business Combination, (x) if the last sale price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date following the completion of the Company’s initial Business Combination on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up Period”).

(b)                                 The Sponsor and each Insider agrees that it or he shall not Transfer any Private Placement Warrants (or Ordinary Shares issued or issuable upon the conversion of the Private Placement Warrants), until 30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

4

(c)                                  Notwithstanding the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, transfers by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) transfers by virtue of the laws of the Cayman Islands or the Sponsor’s memorandum and articles of association upon dissolution of the Sponsor; and (h) in the event of the Company’s completion of a liquidation, merger, share exchange, reorganization or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter into a written agreement agreeing to be bound by the restrictions herein.

8.                                      The Sponsor and each Insider represents and warrants that it or he has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked.  Each Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s background.  Each Insider’s questionnaire furnished to the Company is true and accurate in all respects.  Each Insider represents and warrants that:  it is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it is not currently a defendant in any such criminal proceeding.

9.                                      Except as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment of a loan and advances up to an aggregate of $300,000 made to the Company by the Sponsor; payment to an affiliate of the Sponsor for office space, utilities and secretarial and administrative support for a total of $10,000 per month; reimbursement for any

5

reasonable out-of-pocket expenses related to identifying, investigating and consummating an initial Business Combination, and repayment of loans, if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or any of the Company’s officers or directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment.  Up to $1,500,000 of such loans may be convertible into warrants at a price of $0.50 per warrant at the option of the lender.  Such warrants would be identical to the Private Placement Warrants.

10.                               The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve as a director on the board of directors of the Company and hereby consents to being named in the Prospectus as a director of the Company.

11.                               As used herein, (i) “Business Combination” shall mean a merger, share exchange, asset acquisition, stock purchase, reorganization or similar business combination, involving the Company and one or more businesses; (ii) “Shares” shall mean, collectively, the Ordinary Shares and the Founder Shares; (iii) “Founder Shares” shall mean the 8,625,000 Class B Ordinary Shares, par value $0.0001 per share, initially issued to the Sponsor (or 7,500,000 shares if the over-allotment option is not exercised by the Underwriters) for an aggregate purchase price of $25,000, or approximately $0.003 per share, prior to the consummation of the Public Offering; (iv) “Initial Shareholders” shall mean the Sponsor and any Insider that holds Founder Shares; (v) “Private Placement Warrants” shall mean the Warrants to purchase up to 16,000,000 Ordinary Shares of the Company (or 17,800,000 Ordinary Shares if the over-allotment option is exercised in full) that the Sponsor and certain of the Insiders have agreed to purchase for an aggregate purchase price of $8,000,000 in the aggregate (or $8,900,000 if the over-allotment option is exercised in full), or $0.50 per Warrant, in a private placement that shall occur simultaneously with the consummation of the Public Offering; (vi) “Public Shareholders” shall mean the holders of securities issued in the Public Offering; (vii) “Trust Account” shall mean the trust fund into which a portion of the net proceeds of the Public Offering shall be deposited; and (viii) “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder with respect to, any security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b).

12.                               This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they

6

relate in any way to the subject matter hereof or the transactions contemplated hereby.  This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.

13.                               No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other party.  Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee.  This Letter Agreement shall be binding on the Sponsor and each Insider and their respective successors, heirs and assigns and permitted transferees.

14.                               This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.  The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

WHEREAS, pursuant to the Underwriting Agreement, a portion of the Property equal to $10,500,000, or $12,075,000 if the Underwriters’ over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that may be payable by the Company to the Underwriters upon the consummation of the Business Combination (as defined below) (the “Deferred Discount”); and

WHEREAS, the Company and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold the Property.

NOW THEREFORE, IT IS AGREED:

1.                                      Agreements and Covenants of Trustee.  The Trustee hereby agrees and covenants to:

(a)                                 Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by the Trustee at a branch office of J.P. Morgan Chase Bank, N.A. located in the United States and at a brokerage institution selected by the Trustee that is reasonably satisfactory to the Company;

(b)                                 Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein;

(c)                                  In a timely manner, upon the written instruction of the Company, invest and reinvest the Property in United States government securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 180 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended, which invest only in direct U.S. government treasury obligations, as determined by the Company; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder;

(d)                                 Collect and receive, when due, all interest or other income arising from the Property, which shall become part of the “Property,” as such term is used herein;

(e)                                  Promptly notify the Company and Credit Suisse Securities (USA) LLC of all communications received by the Trustee with respect to any Property requiring action by the Company;

(f)                                   Supply any necessary information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account;

(g)                                  Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so;

(h)                                 Render to the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account;

(i)                                     Commence liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B signed on behalf of the Company by its Chief Executive Officer, President, Chief Financial Officer, Secretary or Chairman of the board of directors (the “Board”) of the Company or other authorized officer of the Company, and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest (which interest shall be net of any taxes payable and less up to $50,000 of interest that may be released to the Company to pay dissolution expenses, it being understood that the Trustee has no obligation to monitor or question the Company’s position that an allocation has been made for taxes payable), only as directed in the Termination Letter and the other documents referred to therein; provided, that, in the case a Termination Letter in the form of Exhibit A is received, or (y) upon the date which is 24 months after the closing of the Offering, if a Termination Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest (which interest shall be net of any taxes payable and less up to $50,000 of interest that may be released to the Company to pay dissolution expenses), shall be

2

distributed to the Public Shareholders of record as of such date; provided, however, that in the event the Trustee receives a Termination Letter in a form substantially similar to Exhibit B hereto, or if the Trustee begins to liquidate the Property because it has received no such Termination Letter by the date which is 24 months after the closing of the Offering, the Trustee shall keep the Trust Account open until twelve (12) months following the date the Property has been distributed to the Public Shareholders;

(j)                                    Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company in writing to make such distribution so long as there is no reduction in the principal amount initially deposited in the Trust Account; provided further however, that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill for the Company and a written statement from the principal financial officer of the Company setting forth the actual amount payable (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account).  The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request;

(k)                                 Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit D (a “Shareholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be used to redeem Ordinary Shares from Public Shareholders properly submitted in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to redeem 100% of its public Ordinary Shares if the Company has not consummated an initial Business Combination within such time as is described in the Company’s amended and restated memorandum and articles of association. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and

(l)                                     Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j) or (k) above.

2.                                      Agreements and Covenants of the Company.  The Company hereby agrees and covenants to:

3

(a)                                 Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer or Secretary.  In addition, except with respect to its duties under Sections 1(i), 1(j) or 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing;

(b)                                 Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct.  Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified Claim”).  The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably withheld.  The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld.  The Company may participate in such action with its own counsel;

Re:  Trust Account No.                  Termination Letter

Gentlemen:

Pursuant to Section 1(i) of the Investment Management Trust Agreement between Avista Healthcare Public Acquisition Corp. (the “Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of [·], 2016 (the “Trust Agreement”), this is to advise you that the Company has entered into an agreement with                  (the “Target Business”) to consummate a business combination with Target Business (the “Business Combination”) on or about [insert date].  The Company shall notify you at least forty-eight (48) hours in advance of the actual date of the consummation of the Business Combination (“Consummation Date”).  Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.

In accordance with the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account on [insert date], and to transfer the proceeds into the above-referenced trust checking account at J.P. Morgan Chase Bank, N.A.  to the effect that, on the Consummation Date, all of funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Company and Credit Suisse Securities (USA) LLC (“Credit Suisse”) (with respect to the Deferred Discount) shall direct on the Consummation Date.  It is acknowledged and agreed that while the funds are on deposit in the trust checking account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor Credit Suisse will earn any interest or dividends.

On the Consummation Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated substantially concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company shall deliver to you (a) [an affidavit] [a certificate] of the Chief Executive Officer, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders, if a vote is held and (b) joint written instruction signed by the Company and Credit Suisse with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount from the Trust Account (the “Instruction Letter”).  You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance with the terms of the Instruction Letter.  In the event that certain deposits held in the Trust Account

may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company.  Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated.

In the event that the Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified you on or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust Account shall be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation Date as set forth in the notice as soon thereafter as possible.

2.1.1                     Request for Registration.  Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, at any time and from time to time on or after the date the Company consummates the Business Combination, the Holders of at least a majority in interest of the then outstanding number of Registrable Securities (the “Demanding Holders”) may make a written demand for Registration under the Securities Act of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”).  The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company.  Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall effect, as soon thereafter as practicable, but not more than forty five (45) days immediately after the Company’s receipt of the Demand Registration, the Registration of all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such Demand Registration.  Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however, that a Registration shall not be counted for such purposes unless a Form S-1 or any similar long-form registration statement that may be available at such time (“Form S-1”) has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the

5

Requesting Holders in such Form S-1 Registration have been sold, in accordance with Section 3.1 of this Agreement.

2.1.2                     Effective Registration.  Notwithstanding the provisions of subsection 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, further, that if, after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

2.1.3                     Underwritten Offering.  Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein.  All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the majority-in-interest of the Demanding Holders initiating the Demand Registration.

2.1.4                     Reduction of Underwritten Offering.  If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other Ordinary Shares or other equity securities that the Company desires to sell and the Ordinary Shares, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other shareholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective

6

number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Ordinary Shares or other equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

2.1.5                     Demand Registration Withdrawal.  A majority-in-interest of the Demanding Holders initiating a Demand Registration or a majority-in-interest of the Requesting Holders (if any), pursuant to a Registration under subsection 2.1.1 shall have the right to withdraw from a Registration pursuant to such Demand Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to the Registration of their Registrable Securities pursuant to such Demand Registration.  Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5.

2.2                               Piggyback Registration.

2.2.1                     Piggyback Rights.  If, at any time on or after the date the Company consummates a Business Combination, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of shareholders of the Company (or by the Company and by the shareholders of the Company), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) days after receipt of such written notice (such Registration a “Piggyback Registration”).  The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to

7

this subsection 2.2.1 to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.  All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company.

2.2.2                     Reduction of Piggyback Registration.  If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggyback Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of the Ordinary Shares that the Company desires to sell, taken together with (i) the Ordinary Shares, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder (ii) the Registrable Securities as to which registration has been requested pursuant Section 2.2 hereof, and (iii) the Ordinary Shares, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other shareholders of the Company, exceeds the Maximum Number of Securities, then:

(a)                                 If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the Ordinary Shares or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Ordinary Shares, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other shareholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(b)                                 If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the Ordinary Shares or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1, pro rata based on the number of Registrable Securities that each Holder has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Registration, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the Ordinary Shares or other equity securities that the Company desires to sell, which can be

8

sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the Ordinary Shares or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.2.3                     Piggyback Registration Withdrawal.  Any Holder of Registrable Securities shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration.  The Company (whether on its own good faith determination or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration at any time prior to the effectiveness of such Registration Statement.  Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this subsection 2.2.3.

2.2.4                     Unlimited Piggyback Registration Rights.  For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof.

2.3                               Registrations on Form S-3.  The Holders of Registrable Securities may at any time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or similar short-form registration statement that may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering.  Within five (5) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within ten (10) days after the receipt by the Holder of the notice from the Company.  As soon as practicable thereafter, but not more than twelve (12) days after the Company’s initial receipt of such written request for a Registration on Form S-3, the Company shall register all or such portion of such Holder’s Registrable Securities as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if (i) a Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $5,000,000.

2.4                               Restrictions on Registration Rights.  If (A) during the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company initiated Registration and provided that the Company has delivered written notice to the Holders prior to receipt of a Demand Registration pursuant to subsection 2.1.1 and it continues to actively employ, in good faith, all reasonable efforts to cause the applicable Registration Statement to become effective; (B) the Holders have requested an Underwritten Registration and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (C) in the good faith judgment of the Board such Registration would be seriously detrimental to the Company and the Board concludes as a result that it is essential to defer the filing of such Registration Statement at such time, then in each case the Company shall furnish to such Holders a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental to the Company for such Registration Statement to be filed in the near future and that it is therefore essential to defer the filing of such Registration Statement.  In such event, the Company shall have the right to defer such filing for a period of not more than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more than once in any 12-month period.  Notwithstanding anything to the contrary contained in this Agreement, no Registration shall be effected or permitted and no Registration Statement shall become effective, with respect to any Registrable Securities held by any Holder, until after the expiration of the Founder Shares Lock-Up Period or the Private Placement Lock-Up Period, as the case may be.

ARTICLE III

11

3.1.10              permit a representative of the Holders, the Underwriters, if any, and any attorney or accountant retained by such Holders or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriters enter into a confidentiality agreement, in form and substance reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.11              obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Registration, in customary form and covering such matters of the type customarily covered by “cold comfort” letters as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

3.1.12              on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration, addressed to the Holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority in interest of the participating Holders;

3.2                               Registration Expenses.  The Registration Expenses of all Registrations shall be borne by the Company.  It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set

12

forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Holders.

3.3                               Requirements for Participation in Underwritten Offerings.  No person may participate in any Underwritten Offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting agreements and other customary documents as may be reasonably required under the terms of such underwriting arrangements.

3.4                               Suspension of Sales; Adverse Disclosure.  Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.  If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would require the Company to make an Adverse Disclosure or would require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more than thirty (30) days, determined in good faith by the Company to be necessary for such purpose.  In the event the Company exercises its rights under the preceding sentence, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.  The Company shall immediately notify the Holders of the expiration of any period during which it exercised its rights under this Section 3.4.

3.5                               Reporting Obligations.  As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings.  The Company further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Ordinary Shares held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions.  Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV
INDEMNIFICATION AND CONTRIBUTION

4.1                               Indemnification.

4.1.1                     The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers and directors and each person who controls such Holder (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and expenses (including attorneys’ fees) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder expressly for use therein.  The Company shall indemnify the Underwriters, their officers and directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2                     In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and officers and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including without limitation reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement.  The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3                     Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party.  If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld).  An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying

14

party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim.  No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4                     The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities.  The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5                     If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations.  The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability.  The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.  The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.
