The Firm Securities and the Option Securities are herein referred to as the “Securities.” The Securities will be convertible into shares (the “Underlying Securities”) of Class A common stock of the Company, par value $0.01 per share (the “Class A Common Stock”). The Securities will be issued pursuant to an Indenture to be dated as of December 5, 2016 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). Class A Common Stock of the Company, together with the shares of Class B Common Stock, par value $0.01 per share, of the Company (the “Class B Common Stock”), is referred to herein as the “Stock.”

Pursuant to the Agreement and Plan of Merger dated as of July 12, 2016, as amended on October 3, 2016, by and among the Company, Electra Merger Sub, LLC, a Delaware limited

Immediately following the issuance of Class A Common Stock upon closing of the acquisition of the Acquired Business, the Company transferred its membership interests in Merger Sub to Evolent Health LLC, a Delaware limited liability company (“Evolent Health”) and Evolent Health issued a number of its Class A common units to the Company equal to the number of shares of Class A Common Stock issued at closing of the acquisition of the Acquired Business.

(o)No General Solicitation. None of the Company or any of its controlled affiliates or any other person on its or their behalf (other than the Initial Purchasers, as to

7.Indemnification and Contribution.

(a)Indemnification of the Initial Purchasers by the Company and Evolent Health. Each of the Company and Evolent Health agrees to jointly and severally indemnify and hold harmless each Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable legal fees and other reasonable expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication, any road show as defined in Rule 433(h) under the Securities Act, or the Offering Memorandum (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in subsection (b) below.

(b)Indemnification of the Company and Evolent Health. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company and Evolent Health and their respective directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information (including any of the other Time of Sale Information that has subsequently been amended), any Issuer Written Communication, any road show or the Offering Memorandum (or any amendment or supplement thereto) it being understood and agreed upon that the only such information furnished by any Initial Purchaser consists of the following information in the Offering Memorandum furnished on behalf of each Initial Purchaser: the information contained in the twelfth and thirteenth paragraphs under the caption “Plan of Distribution.”

(c)Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted

against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 7, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 7 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person 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 Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by J.P. Morgan Securities LLC and Goldman, Sachs & Co., and any such separate firm for the Company, its directors, its officers and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for reasonable fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into in good faith more than 60 days after receipt by the Indemnifying Person of such request and more than 30 days after receipt of the proposed terms of such settlement and (ii) the Indemnifying Person shall

not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Initial Purchasers on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand, and the Initial Purchasers on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company, on the one hand, and the Initial Purchasers on the other, 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 or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)Limitation on Liability. The Company, Evolent Health and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be

required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)Non-Exclusive Remedies.The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8.Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9.Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date, (i) trading generally shall have been suspended or materially limited on or by any of the Exchange or The Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

10.Defaulting Initial Purchaser.

(a)If, on the Closing Date or the Additional Closing Date, as the case may be, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non‑defaulting Initial Purchasers or the Company may postpone the Closing Date or the

Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b)If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the number of Securities that such Initial Purchaser agreed to purchase hereunder on such date plus such Initial Purchaser’s pro rata share (based on the number of Securities that such Initial Purchaser agreed to purchase on such date) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c)If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of Securities to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Initial Purchasers to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d)Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default.

(a)Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and Evolent Health jointly and severally will pay or cause to be paid all costs and expenses incident to the performance of their obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing the Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company and Evolent Health’s counsel and the Company’s independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the state or foreign securities or blue sky laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers up to $5,000); (vi) any fees charged by rating agencies for rating the Securities, if any; (vii) the fees and expenses of the Trustee and any paying agent (including related reasonable fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; provided, however, that the Initial Purchasers shall be responsible for 50% of the third-party costs of any private aircraft incurred in connection with such road show; and (x) all expenses and application fees related to the listing of the Underlying Securities on the Exchange.

(b)If (i) this Agreement is terminated pursuant to Section 9 (other than as a result of a termination pursuant to clauses (i), (iii) or (iv) of Section 9), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers (other than as a result of a termination pursuant to clauses (i), (iii) or (iv) of Section 9 or Section 10) or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and Evolent Health jointly and severally agree to reimburse the Initial Purchasers (or, in the case of Section 10, solely the non-defaulting Initial Purchasers) for all documented out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

12.Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No

purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

13.Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, Evolent Health and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, Evolent Health or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, Evolent Health or the Initial Purchasers.

14.Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act and with respect to the Company specifically includes Evolent Health.

L. 107-56 (signed into law October 26, 2001)), the Initial 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 Initial Purchasers to properly identify their respective clients.

Re:    EVOLENT HEALTH, INC. --- Placement

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Initial Purchasers, propose to enter into a purchase agreement (the “Purchase Agreement”) with Evolent Health, Inc., a Delaware corporation (the “Company”) providing for the purchase and resale (the “Placement”) by the several Initial Purchasers named in Schedule 1 to the Purchase Agreement (the “Initial Purchasers”), of Convertible Notes of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Purchase Agreement. References to shares of Common Stock shall be deemed to refer to shares of any class of stock of the Company.

In consideration of the Initial Purchasers’ agreement to purchase and make the Placement of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of J.P. Morgan Securities LLC and Goldman, Sachs & Co. on behalf of the Initial Purchasers, the undersigned will not, during the period beginning on the date of this Letter Agreement and ending 60 days after the date of the offering memorandum relating to the Placement (the “Offering Memorandum”) (such period, the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any

option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock, or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, LLC Units, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale, pledge or disposition, (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock, in each case other than:

(A) [reserved]

(B) (i) transfers of shares of Common Stock as a bona fide gift or gifts, (ii) transfers of shares of Common Stock or such other securities as a result of the operation of law through estate, other testamentary document or intestate succession or (iii) transfers of shares of Common Stock or such other securities to any immediate family member of the undersigned or any trust for the direct or indirect benefit of the undersigned or any immediate family member of the undersigned (for purposes of this Letter Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin);

(C) distributions of shares of Common Stock to the members, limited or general partners or stockholders of the undersigned, its direct or indirect affiliates or other entities controlled or managed by the undersigned;

(D) transfers of shares of Common Stock or other securities acquired in open market transactions after the completion of the Placement;

(E) [reserved];

(F) the exercise of Stock Options to purchase shares of Common Stock and any related transfer to the Company of shares of Common Stock (i) deemed to occur upon the cashless exercise of such Stock Options or (ii) for the purpose of paying the exercise price of such Stock Options or for paying taxes (including estimated taxes) due as a result of the exercise of such Stock Options; provided that any such purchased shares will be subject to the restrictions described in this Letter Agreement;

(G) transfers to the Company of shares of Common Stock or any security convertible into or exercisable for Common Stock in connection with the termination of service of an option to repurchase such shares;

(H) transfers of shares of Common Stock pursuant to a trading plan established prior to the date hereof pursuant to Rule 10b5-1 of the Exchange Act (an “Established Plan”); provided that (i) to the extent a filing under the Exchange Act or public announcement, if any, is required or voluntarily made by or on behalf of the undersigned or the Company regarding any such sales, the undersigned shall cause such announcement or filing to include a statement to the effect that the sale was made pursuant to an Established Plan, and (ii) the undersigned may not amend, alter or modify an Established Plan during the Restricted Period; [or

(I) transfers of shares of Common Stock or such other securities to any investment fund controlled or managed by any affiliate of TPG Global, LLC and its affiliates;]

provided that in the case of any transfer or distribution pursuant to clause (B) or (C) [or (I)], each donee or distributee shall execute and deliver to the Representatives a lock-up letter in the form of this paragraph; and provided, further, that in the case of any transfer or distribution pursuant to clause (B) through [(G)][ or (I)], no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5, Schedule 13D or Schedule 13G, in each case, in accordance with applicable law and made after the expiration of the Restricted Period).

In addition, nothing in this Letter Agreement shall prohibit the undersigned from (i) transferring shares of Common Stock pursuant to a liquidation, tender offer, merger, consolidation, stock exchange or similar transaction that results in all of the Company’s equity holders having the right to exchange their equity securities in the Company for cash, securities or other property; provided that if such liquidation, tender offer, merger, consolidation, stock exchange or similar transaction is not completed, any Common Stock or other equity securities in the Company subject to this Letter Agreement shall remain subject to the restrictions contained in this Letter Agreement or (ii) engaging in any transaction to the extent required by law, regulation or governmental order.

Furthermore, the undersigned may, if permitted by the Company, establish a written trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act; provided that no sales or other transfers occur under such plan and no public disclosure of such plan shall be required or shall be made by any person during the Restricted Period.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if (i) prior to entering into the Purchase Agreement, the Company notifies the Representatives in writing that the Company does not intend to proceed with the Placement; (ii) the Purchase Agreement has not been executed by all parties by December 16, 2016; or (iii) if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, then this Letter Agreement shall immediately terminate and the undersigned shall be released from all obligations under this Letter Agreement. The undersigned understands that the Initial Purchasers are entering into the Purchase Agreement and proceeding with the Placement in reliance upon this Letter Agreement.

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Very truly yours,

[NAME OF STOCKHOLDER]
