public stockholders properly demanding redemption in connection with the Extension Amendment; and extend the date on which to commence
liquidating the trust account in the event the Company has not consummated a business combination from the Original Termination
Date to the Extended Termination Date (the “Trust Amendment”);

WHEREAS, holders of at least
sixty-five percent (65%) of the Company’s outstanding shares of common stock approved the Trust Amendment and the Extension
Amendment; and

WHEREAS, the parties desire
to amend and restate the Original Agreement to, among other things, reflect amendments to the Original Agreement contemplated by
the Trust Amendment.

NOW THEREFORE, IT IS AGREED:

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

(a)      Hold

(h)      Render
to the Company, and to such other person as the Company may instruct, monthly written statements of the activities of, and amounts

liquidation of the Trust Account only after and promptly after receipt of, and only in accordance with, the terms of a letter (“Termination
Letter”), in a form substantially similar to that attached hereto as either Exhibit A or  Exhibit
B hereto, signed on behalf of the Company by an executive officer and complete the liquidation of the Trust Account and distribute
the Property in the Trust Account only as directed by the Company; provided, however, that in the event that a Termination
Letter has not been received by the Trustee by 11:59 P.M. New York City time on the 27-month anniversary of the date of the final
prospectus relating to the IPO, the Trust Account shall be liquidated as soon as practicable thereafter in accordance with the
procedures set forth in the Termination Letter attached as Exhibit B hereto and distributed to the Public Stockholders of
record at the close of trading (4:00 P.M. New York City time) on such 27 month anniversary date.  For the purposes of
clarity, any transmission of such Termination Letter electronically, whether by facsimile, electronic mail (e-mail), PDF or otherwise,
shall constitute an original of such termination Letter hereunder.

2.        Limited
Distributions of Income from Trust Account.

(a)       Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto

pay such Public Stockholders. For the purposes of clarity, any transmission of such letter electronically, whether by facsimile,
electronic mail (e-mail), PDF or otherwise, shall constitute an original of such letter hereunder.

(d)      In
no event shall the payments authorized by Sections 2(a) and 2(b) cause the amount in the Trust Account to fall below
the amount initially deposited into the Trust Account.  Except as provided in Sections 2(a), 2(b) and 2(c)
above, no other distributions from the Trust Account shall be permitted except in accordance with Section 1(i) hereof.

(e)       The
written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to such funds,
and the Trustee has no responsibility to look beyond said request.

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

(a)       Give
all instructions to the Trustee hereunder in writing or the electronic equivalent, signed by the Company’s President, Chief

confirm such instructions in writing;

    	3

    	 

    

 

(b)      Subject
to the provisions of Section 5, 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 the
trustee hereunder or any claim, potential claim, 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 income earned from investment of the Property, except for expenses and losses resulting from
the Trustee’s gross negligence 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, 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 consent shall not
be unreasonably withheld.  The Company may participate in such action with its own counsel;

(c)       Pay
the Trustee the fees set forth on Schedule A hereto;

connection with the vote, if any, of the Company’s stockholders regarding a Business Combination, provide to the Trustee

Company agrees that it will not direct the Trustee to make any payments that are not specifically authorized by this Agreement.

Underwriters) of the total amount of the Deferred Fee.

4.        Limitations

Imply obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this
agreement and that which is expressly set forth herein;

any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of

(g)      The
other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted,
in good faith and in the exercise of its own best judgment, except for its gross negligence or willful misconduct.  The
Trustee may rely conclusively and shall be protected in acting upon any order, judgment, instruction, notice, demand, certificate,
opinion or advice of counsel (including counsel chosen by the Trustee, which counsel may be Company counsel), statement, instrument,
report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but
also as to the truth and acceptability of any information therein contained) which is believed by the Trustee, in good faith,
to be genuine and to be signed or presented by the proper person or persons.  The Trustee shall not be bound by any
notice or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless
evidenced by a written instrument delivered to the Trustee signed by the proper party or parties and, if the duties or rights
of the Trustee are affected, unless it shall give its prior written consent thereto;

(h)      Verify
the correctness of the information set forth in the Registration Statement or to confirm or assure that any acquisition made by
the Company or any other action taken by it is as contemplated by the Registration Statement; and

(i)        Prepare,
execute and file tax reports, income or other tax returns and pay any taxes with respect to income and activities relating to
the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company (including but not limited to
income tax obligations), it being expressly understood that as set forth in Section 2(a), if there is any income or other
tax obligation relating to the Trust Account or the Property in the Trust Account, as determined from time to time by the Company
and regardless of  whether such tax is payable by the Company or the Trust, at the written instruction of the Company,
the Trustee shall make funds available in cash from the Property in the Trust Account an amount specified by the Company as owing
to the applicable taxing authority, which amount shall be paid directly to the Company by electronic funds transfer, account debit
or other method of payment, and the Company shall forward such payment to the taxing authority;

(j)        Pay
or report any taxes on behalf of the Trust Account other than pursuant to Section 2(a).

(k)       Verify
calculations, qualify or otherwise approve Company requests for distributions pursuant to Sections 1(i), 2(a), 2(b)
or 2(c).

5.        No
Right of Set-Off.  The Trustee waives any right of set-off or any right, title, interest or claim of any kind that
the Trustee may have against the Property held in the Trust Account.  In the event the Trustee has a claim against the
Company under this Agreement, including, without limitation, under Section 3(b), the Trustee will pursue such claim solely
against the Company and not against the Property held in the Trust Account.

6.        Termination.  This
Agreement shall terminate as follows:

(a)       If
the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee during which time the Trustee shall act in accordance with this Agreement.  At
such time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to become
subject to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee,
including but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this
Agreement shall terminate; provided, however, that, in the event the Company does not locate a successor trustee within ninety
(90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited
with any court in the State of New York or with the United States District Court for the Southern District of New York and upon
such deposit, the Trustee shall be immune from any liability whatsoever; or

    	5

    	 

    

 

(b)      At
such time that the Trustee has completed the liquidation of the Trust Account in accordance with the provisions of Section 1(i)
hereof, and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate
except with respect to Section 3(b).

7.        Miscellaneous.

(a)       The
Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds
transferred from the Trust Account.  The Company and the Trustee will each restrict access to confidential information
relating to such security procedures to authorized persons.  Each party must notify the other party immediately if it
has reason to believe unauthorized persons may have obtained access to such information, or of any change in its authorized personnel.  In
executing funds transfers, the Trustee will rely upon all information supplied to it by the Company, including, account names,
account numbers, and all other identifying information relating to a beneficiary, beneficiary’s bank or intermediary bank.
The Trustee shall not be liable for any loss, liability or expense resulting from any error in the information or transmission
of the wire. 

(b)      This
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.  It
may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together shall
constitute but one instrument.

(c)       This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof.  Except
for Sections 1(i), 2(a), 2(b), 2(c) and 2(d) (which may not be modified, amended or deleted
without the affirmative vote of at least 65% of the then outstanding shares of Common Stock; provided that no such
amendment will affect any Public Stockholder who has otherwise either (i) indicated his election to redeem his shares of Common
Stock in connection with a stockholder vote sought to amend this Agreement or (ii) not consented to any amendment to this Agreement
to extend to the time he would be entitled to a return of his pro rata amount in the Trust Account), this Agreement or any provision
hereof may only be changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the
parties hereto.  As to any claim, cross-claim or counterclaim in any way relating to this Agreement, each party waives
the right to trial by jury and the right to set-off as a defense.  The Trustee may request an opinion from Company counsel
as to the legality of any proposed amendment as a condition to its executing such amendment.

(d)      The
parties hereto consent to the personal jurisdiction and venue of any state or federal court located in the City of New York, Borough
of Manhattan, for purposes of resolving any disputes hereunder.

(e)      Unless
otherwise specified herein, any notice, consent or request to be given in connection with any of the terms or provisions of this
Agreement shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt
or delivery confirmation requested), by hand delivery or by electronic  or facsimile transmission:

 Contemporaneously with the closing of the issuance of the Securities, the Company, U.S. Bank
National Association, as Trustee (the “Trustee”) and U.S. Bank National Association, as escrow agent (the “Escrow Agent”), will enter into an Escrow Agreement (the “Escrow Agreement”) pursuant to which at the Time of

September 4, 2014 (the “Offering Memorandum”), will be prepared in connection with the offering of the Securities. The Preliminary Offering Memorandum, as amended and supplemented immediately prior to the Applicable Time (as defined
in Section 1(b)), is hereinafter referred to as the “Pricing Memorandum”. Any reference to the Preliminary Offering Memorandum, the Pricing Memorandum or the Offering Memorandum shall be deemed to refer to and include all documents
filed with the United States Securities and Exchange Commission (the “Commission”) pursuant to Section 13(a), 13(c) or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or prior
to the date of such memorandum and incorporated by reference therein and any reference to the Preliminary Offering Memorandum or the Offering Memorandum, as the case may be, as amended or supplemented, as of any specified date, shall be deemed to
include (i) any documents filed with the Commission pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act after the date of the Preliminary Offering Memorandum or the Offering Memorandum, as the case may be, and prior to such
specified date and (ii) any Additional Issuer Information (as defined in Section 5(f)) furnished by the Company prior to the completion of the distribution of the Securities; and all documents filed under the Exchange Act and so deemed to
be included in the Preliminary Offering Memorandum, the Pricing Memorandum or the Offering Memorandum, as the case may be, or any amendment or supplement thereto are hereinafter called the “Exchange Act Reports” (provided that where only
sections of such documents are specifically incorporated by reference, only such sections shall be considered to be part of the “Exchange Act Reports”). The Exchange Act Reports, when they were or are filed with the Commission, conformed
or will conform in all material respects to the applicable requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder; and no such documents were filed with the Commission since the Commission’s close
of business on the business day immediately prior to the date of this Agreement and prior to the execution of this Agreement, except as set forth on Schedule II(a) hereof. The Preliminary Offering Memorandum or the Offering Memorandum and any

the light of the circumstances under which they were made, not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information

light of the circumstances under which they were made, not misleading; and each Company Supplemental Disclosure Document (as defined in Section 6(a)(i)) listed on Schedule II(b) hereto and each Permitted General Solicitation Material (as
defined in Section 6(a)(i)) listed on Schedule II(d) hereto) does not conflict with the information contained in the Pricing Memorandum or the Offering Memorandum and each such Company Supplemental Disclosure Document and Permitted General
Solicitation Material, as supplemented by and taken together with the Pricing Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that this representation and warranty shall not apply to statements or omissions made in a Company Supplemental Disclosure Document
or Permitted General Solicitation Material in reliance upon and in conformity with information furnished in writing to the Company by a Purchaser through Goldman, Sachs & Co. expressly for use therein; 

 

	 	(c)	Neither the Company nor any of its subsidiaries has sustained since the date of the latest audited financial statements included in the Pricing Disclosure Package any material loss or interference with its business from

respective dates as of which information is given in the Pricing Disclosure Package, there has not been any change in the capital stock, membership interests or long-term debt of the Company or any of

and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification, or is subject to no material liability or disability by reason of the failure to be
so qualified or be in good standing in any such jurisdiction; 

  

	 	(e)	The Company has an authorized capitalization as set forth in the Pricing Disclosure Package and the Offering Memorandum, and all of the issued shares of capital stock of the Company have been duly and validly authorized
and issued and are fully paid and non-assessable; and all of the issued shares of capital stock, membership interests or other equity interests, as applicable, of each subsidiary of the Company have been duly
and validly authorized and issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims; 

 

	 	(f)	The financial statements (including the related notes thereto) of the Company and its consolidated subsidiaries included or incorporated by reference in each of the Pricing Disclosure Package and the Offering Memorandum

clause (iv) or (v) in your judgment makes it impracticable or inadvisable to proceed with the offering or the delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering
Memorandum; 

  

	 	(l)	The Purchasers shall have received an executed copy of the Indenture; 

  

	 	(m)	The Company, the Trustee and the Escrow Agent shall have on or prior to the Time of Delivery executed and delivered the Escrow Agreement, and the Purchasers shall have received a copy thereof, duly executed by the
Company, the Trustee and the Escrow Agent, and all funds shall have been paid into the Escrow Account created under the Escrow Agreement, or arrangements shall have been made to pay such amounts into escrow, which shall include the net proceeds from
the offering of the Securities plus such additional amounts required to be paid by the Company in an aggregate amount sufficient to pay the Special Mandatory Redemption Price; 

 

	 	(n)	The Securities shall be eligible for clearance and settlement through the facilities of DTC; 

  

	 	(o)	The Purchasers shall have received a counterpart of the Registration Rights Agreement that shall have been executed and delivered by a duly authorized officer of the Company; and 

 

	 	(p)	The Company shall have furnished or caused to be furnished to you at the Time of Delivery certificates of officers of the Company satisfactory to you as to the accuracy of the representations and warranties of the
Company herein at and as of such Time of Delivery, as to the performance by the Company of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in subsection (h) of this Section and
as to such other matters as you may reasonably request. 

 9. 
  

	 	(a)	 The Company will indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities, joint or several, to which such
Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, any Permitted General
Solicitation Material or arise out of or are 

  
 23 

	 	
based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Purchaser for any legal or other
expenses reasonably incurred by such Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the
Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by any
Purchaser through Goldman, Sachs & Co. expressly for use therein. 

  

	 	(b)	Each Purchaser, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Memorandum,
the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, or any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged
omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made
in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material,
in reliance upon and in conformity with written information furnished to the Company by such Purchaser through Goldman, Sachs & Co. expressly for use therein; and each Purchaser will reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. 

  

	 	(c)	 Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party
shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the

  
 24 

	 	
commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain
counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying
party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual
or potential differing interests between them. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment
(i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf
of any indemnified party. 

  

	 	(d)	 If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection
(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Purchasers on the other from the offering of
the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying
party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only 

  
 25 

	 	
such relative benefits but also the relative fault of the Company on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchasers on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Purchasers, in each case as set forth in the Offering Memorandum. The relative
fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one
hand or the Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Purchasers agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Purchaser
shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to investors were offered to investors exceeds the amount of any damages which such Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase
obligations and not joint. 

  

	 	(e)	The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to any affiliate, director or
officer of each Purchaser and each person, if any, who controls any Purchaser within the meaning of the Act; and the obligations of the Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers may
otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act. 

 

					
	 10.
	  	      (a)	  	 If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange
for you or another party

	

  
 26 

	 	
or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not
arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase
such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of
such Securities, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Offering Memorandum, or in any other
documents or arrangements, and the Company agrees to prepare promptly any amendments or supplements to the Offering Memorandum which in your opinion may thereby be made necessary. The term “Purchaser” as used in this Agreement shall
include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities. 

 

	 	(b)	If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of
such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Purchaser to purchase the principal amount of Securities which such Purchaser agreed to purchase hereunder and, in addition, to require each non-defaulting
Purchaser to purchase its pro rata share (based on the principal amount of Securities which such Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Purchaser from liability for its default. 

 If, after giving effect to any
arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require
non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement shall thereupon terminate, without liability on the part of any
non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 6 hereof and the indemnity and contribution agreements in
Section 9 hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 

  
 27 

	11.	The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Purchasers, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant
to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Purchaser or any affiliate, director, officer or controlling person of any Purchaser,
or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities. 

  

	12.	If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Purchaser except as provided in Sections 7 and 9 hereof; but, if for any other reason,
the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Purchasers through you for all expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred
by the Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Purchaser except as provided in Sections 7 and 9 hereof. 

 

	13.	In all dealings hereunder, you shall act on behalf of each of the Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Purchaser made or
given by you. 

 All statements, requests, notices and agreements hereunder shall be in writing, and if to the Purchasers shall
be delivered or sent by mail or facsimile transmission to you as the representative at 200 West Street, New York, New York 10282-2198, Attention: Registration Department; and if to the Company shall be delivered or sent by mail or facsimile
transmission to the address of the Company set forth in the Offering Memorandum, Attention: Corporate Secretary; provided, however, that any notice to a Purchaser pursuant to Section 9 hereof shall be delivered or sent by mail or
facsimile transmission to such Purchaser at its address set forth in its Purchasers’ Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon
receipt thereof. 
 In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)), the Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other
information that will allow the Purchasers to properly identify their respective clients. 
  

	14.	This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person
who controls the Company or any Purchaser, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities
from any Purchaser shall be deemed a successor or assign by reason merely of such purchase. 

  
 28 

	15.	Time shall be of the essence of this Agreement. 

  

	16.	The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several
Purchasers, on the other, (ii) in connection therewith and with the process leading to such transaction each Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Purchaser has assumed an
advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Purchaser has advised or is currently advising the Company on other matters)
or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not
claim that the Purchaser, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. 

 

	17.	This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Purchasers, or any of them, with respect to the subject matter hereof. 

 

	18.	THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN
THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. The Company agrees that any suit or proceeding arising in respect of this agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern
District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company agrees to submit to the jurisdiction of, and to venue in, such courts.

  

	19.	The Company and each of the Purchasers hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this
Agreement or the transactions contemplated hereby. 

  

	20.	This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one
and the same instrument. 

  

	21.	 Notwithstanding anything herein to the contrary, the Company (and the Company’s employees, representatives, and other agents) are authorized to
disclose to any and all persons, the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax 

  
 29 

	 	
opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Purchasers’ imposing any limitation of any kind. However, any information
relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax treatment” means US
federal and state income tax treatment, and “tax structure” is limited to any facts that may be relevant to that treatment. 

  
 30 

 If the foregoing is in accordance with your understanding, please sign and return to us four counterparts hereof,
and upon the acceptance hereof by you, on behalf of each of the Purchasers, this letter and such acceptance hereof shall constitute a binding agreement among each of the Purchasers and the Company. It is understood that your acceptance of this
letter on behalf of each of the Purchasers is pursuant to the authority set forth in a form of Agreement among Purchasers, the form of which shall be submitted to the Company for examination upon request, but without warranty on your part as to the
authority of the signers thereof.
