(g) Such Selling Shareholder has not taken, and will not take, directly or indirectly, any action which is designed to or which has constituted or would be expected to cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares.

3. Agreements to Sell and Purchase. Each Selling Shareholder, severally and not jointly, hereby agrees to sell to the Underwriter, and the Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees to purchase the Shares from such Selling Shareholder at $77.37 a share (the “Purchase Price”).

The Company hereby agrees that, without the prior written consent of the Underwriter, it will not, during the period ending 30 days after the date of the Prospectus (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, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Exchange Act) or any other securities so owned or convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, 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) file any registration statement or a prospectus supplement to any registration statement, in each case, with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock for the account of the Company (other than a Registration Statement on Form S-8 to register shares of Common Stock issued pursuant to, or covered by, any equity benefit plan or arrangement disclosed in the Time of Sale Prospectus).

The restrictions contained in the preceding paragraph shall not apply to (a) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof that is disclosed in the Time of Sale Prospectus or of which the Underwriter has been advised in writing, (b) any awards granted pursuant to any equity benefit plan or arrangement disclosed in the Time of Sale Prospectus (including in the exhibits to any documents incorporated by reference therein), and (c) the issuance by the Company of up to 10.0% of the shares of Common Stock outstanding after the offering of the Shares or any securities convertible into or exercisable or exchangeable for Common Stock in connection with mergers or acquisitions, joint ventures, commercial relationships or other strategic transactions if each person receiving shares pursuant to this clause (c) enters into an agreement in the form of Exhibit A hereto for the balance of the Restricted Period.

5. Payment and Delivery. Payment for the Shares to be sold by each Selling Shareholder shall be made to such Selling Shareholder in Federal or other funds immediately available in New York City against delivery of such Shares for the account of the Underwriter at 10:00 a.m., New York City time, on August 5, 2015 or at such other time on the same or such other date, not later than August 7, 2015, as shall be mutually agreed by you and the Selling Shareholders. The time and date of such payment are hereinafter referred to as the “Closing Date.”

The Shares shall be registered in such names and in such denominations as you shall request in writing not later than one full business day prior to the Closing Date. The Shares shall be delivered to you on the Closing Date. The Purchase Price payable by the Underwriter shall be reduced by (i) any transfer taxes paid by, or on behalf of, the Underwriter in connection with the transfer of the Shares to the Underwriter duly paid and (ii) any withholding required by law.

6. Conditions to the Underwriter’s Obligations. The obligations of the Selling Shareholders to sell the Shares to the Underwriter and the obligations of the Underwriter to purchase and pay for the Shares on the Closing Date are subject to the following conditions:

A prospectus containing the Rule 430A Information shall have been filed with the Commission in the manner and within the time frame required by Rule 424(b) without reliance on Rule 424(b)(8) or a post-effective amendment providing such information shall have been filed with, and declared effective by, the Commission in accordance with the requirements of Rule 430A; and

(b) that FINRA has confirmed that it has not raised any objection with respect to the fairness and reasonableness of the underwriting terms and arrangements.

The obligations of the Underwriter are subject to the following further conditions:

(i) there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any of the securities of the Company or any of its subsidiaries by any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act; and

(ii) there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Time of Sale Prospectus that, in your judgment, is material and adverse and that makes it, in your judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus.

(d) The Underwriter shall have received on the Closing Date a certificate, dated the Closing Date and signed on behalf of the Company by an executive officer of the Company, to the effect that the representations and warranties of the Company contained in this Agreement are true and correct as of the Closing Date and that the Company has complied in all material respects with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before the Closing Date.

(j) The “lock-up” agreements, each substantially in the form of Exhibit A, between the Underwriter and certain shareholders, officers and directors of the Company relating to sales and certain other dispositions of shares of Common Stock or certain other securities, delivered to the Underwriter on or before the date hereof, shall be in full force and effect on the Closing Date.

7. Covenants of the Company. The Company covenants with the Underwriter as follows:

(a) To furnish to you, without charge, four conformed copies of the Registration Statement (including exhibits thereto) and to furnish to you in New York City, without charge, as soon as practicable but in no event later than 11:00 a.m. New York City time on the second business day next succeeding the date of this Agreement and during the period mentioned in Section 7(e) or 7(f) below, as many copies of the Time of Sale Prospectus, the Prospectus, any documents incorporated therein by reference and any supplements and amendments thereto or to the Registration Statement as you may reasonably request.

(b) Before amending or supplementing the Registration Statement, the Time of Sale Prospectus or the Prospectus, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule.

(c) To furnish to you a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which you reasonably object.

(d) Not to take any action that would result in the Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Securities Act a free writing prospectus prepared by or on behalf of the Underwriter that the Underwriter otherwise would not have been required to file thereunder.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not

misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the reasonable opinion of counsel for the Underwriter, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriter and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Shares as the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by the Underwriter or a dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the reasonable opinion of counsel to the Underwriter, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriter and to the dealers (whose names and addresses you will furnish to the Company) to which Shares may have been sold by you and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(g) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request; provided, however, that nothing herein shall require the Company or any of its subsidiaries to qualify to do business in any jurisdiction, to execute a general consent to service of process in any jurisdiction or to subject itself to taxation in any jurisdiction in which it is not otherwise subject.

(h) To make generally available to the Company’s security holders and to you as soon as practicable an earning statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(i) If any Selling Shareholder is not a U.S. person for U.S. federal income tax purposes, the Company will deliver to the Underwriter (or its agent), on or before the Closing Date, (i) a certificate with respect to the Company’s status as a “United States real property holding corporation,” dated not more than thirty (30) days prior to the Closing Date, as described in Treasury Regulations Sections 1.897-2(h) and 1.1445-2(c)(3), and (ii) proof of delivery to the IRS of the required notice, as described in Treasury Regulations 1.897-2(h)(2).

8. Covenants of the Selling Shareholders. Each Selling Shareholder, severally and not jointly, covenants with the Underwriter as follows:

(a) Each Selling Shareholder will deliver to the Underwriter (or its agent), prior to or at the Closing Date, a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or an IRS Form W-8, as appropriate, together with all required attachments to such form.

9. Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of the Company’s and the Selling Shareholders’ obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel, the Company’s accountants and one counsel for the Selling Shareholders in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriter and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriter, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws, and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 7(g) hereof, including filing fees and the reasonable fees and disbursements of counsel to the Underwriter in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees, and the reasonable fees and disbursements of counsel to the Underwriter, incurred in connection with the review and qualification of the offering of the Shares by the Financial Industry Regulatory Authority, Inc. (provided, however, that the amount payable by the Company for fees and disbursements of counsel to the Underwriter pursuant to clauses (iii) and (iv) shall not exceed $50,000) (v) the cost of printing certificates representing the Shares, (vi) the costs and charges of any transfer agent, registrar or depositary, (vii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and 50% of the cost of any aircraft chartered in connection with the road show, (viii) the document production charges and expenses associated with printing this Agreement and (ix) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section, Section 11 entitled “Indemnity and Contribution” and the last paragraph of Section 13 below, the Underwriter will pay all of its costs and expenses, including fees and disbursements of its counsel, stock transfer taxes payable on resale of any of the Shares by it and any advertising expenses connected with any offers it may make.

The provisions of this Section shall not supersede or otherwise affect any agreement that the Company and the Selling Shareholders may otherwise have for the allocation of such expenses among themselves.

10. Covenants of the Underwriter. The Underwriter covenants with the Company (i) not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of the Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter, and (ii) that the Underwriter shall not include any “issuer information” (as defined in Rule 433) in any “free writing prospectus” (as defined in Rule 405) used or referred to by the Underwriter without the prior written consent of the Company, other than issuer information that is included (including through incorporation by reference) in a prospectus or free writing prospectus previously filed that relates to the Shares.

11. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless the Underwriter, each person, if any, who controls the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of the Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use therein.

(b) Each Selling Shareholder agrees, severally and not jointly, to indemnify and hold harmless the Underwriter, each person, if any, who controls the Underwriter within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein 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 reliance upon and in conformity with the Selling Shareholder Information furnished by such Selling Shareholder. The liability of each Selling Shareholder under the indemnity and contribution agreements contained in this Section 11 shall be limited to an amount equal to (i) the number of Shares sold by such Selling Shareholder under this Agreement multiplied by (ii) the Public Offering Price (minus related underwriting discounts and commissions).

(c) The Underwriter agrees to indemnify and hold harmless the Company, the Selling Shareholders, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any Selling Shareholder within the meaning of either 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, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged

omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but only with reference to information relating to the Underwriter furnished to the Company in writing by the Underwriter expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, or the Prospectus or any amendment or supplement thereto.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11(b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonable fees and disbursements of such counsel related to such proceeding. 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 retention of such counsel or (ii) the named parties to 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. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Underwriter and all persons, if any, who control the Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of the Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Shareholders and all persons, if any, who control any Selling Shareholder within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriter and such control persons and affiliates of the Underwriter, such firm shall be designated in writing by the Underwriter. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of any Selling Shareholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Shareholders under the Powers of Attorney. The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall,

without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(e) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 11(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand 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 and the Selling Shareholders on the one hand and the Underwriter on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each Selling Shareholder and the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company and the Selling Shareholders on the one hand and the Underwriter on the other hand 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 (x) the Company or the Selling Shareholders or (y) by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Selling Shareholders’ respective obligations to contribute pursuant to this Section 11(e) are several, and not joint, and shall be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each Selling Shareholder.

(f) The Company, the Selling Shareholders and the Underwriter agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, 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 Section 11, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter 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 remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Underwriter, any person controlling the Underwriter or any affiliate of the Underwriter, any Selling Shareholder or any person controlling any Selling Shareholder, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

(h) The provisions contained in this Section 11 shall not affect any agreement among the Company and the Selling Shareholders with respect to indemnification or contribution.

12. Termination.

The undersigned understands that Morgan Stanley & Co. LLC (the “Underwriter”), proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Quintiles Transnational Holdings Inc., a North Carolina corporation (the “Company”), and certain selling shareholders of the Company providing for the public offering (the “Public Offering”) by the Underwriter of shares (the “Shares”) of the common stock, par value $0.01 per share, of the Company (the “Common Stock”).

To induce the Underwriter to continue its efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Underwriter, the undersigned will not, during the period commencing on the date hereof and ending 30 days after the date of the final prospectus supplement [(the “Prospectus)]¹ relating to the Public Offering (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, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, 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.

(a) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock by will or intestate succession,

(b) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock as a bona fide gift,

(c) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to any member of the immediate family of the undersigned, or to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned,

(d) distributions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to partners, members, stockholders or holders of similar equity interests in the undersigned,

(e) transfers of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock to a corporation, partnership, limited liability company, investment fund or other entity that controls or is controlled by, or is under common control with, the undersigned, or is wholly-owned by the undersigned and/or by members of the immediate family of the undersigned, or, in the case of an investment fund, that is managed by, or is under common management with, the undersigned,

(f) dispositions of shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock acquired in open market transactions after the completion of the Public Offering,

(g) transfers of shares of Common Stock by the undersigned on the date of the Underwriting Agreement in connection with bona fide gifts of shares of Common Stock by certain partners and employees of the undersigned, its affiliates or funds advised by the undersigned or its affiliates to charitable organizations,

(h) dispositions solely in connection with the “cashless” exercise of stock options (the term “cashless” exercise being intended to include the sale of a portion of the option shares or previously owned shares to the Company to cover payment of the exercise price) for the purpose of exercising such stock options solely in the case of termination of employment or board service following death, disability or other than for cause (including sales in respect of tax liabilities arising from such exercise and sale) if such stock options would otherwise expire, provided that any shares of Common Stock received upon such exercise shall be subject to all of the restrictions set forth in this agreement,

(i) dispositions to the Company in exercise of the Company’s right to repurchase or reacquire the undersigned’s securities pursuant to agreements in effect on the date hereof, including without limitation the Company’s equity incentive plans, that permit the Company to repurchase or reacquire such securities upon termination of the undersigned’s services to the Company, [and]

(j) sales of shares of Common Stock pursuant to the Underwriting Agreement, [and]

[(k) the pledge of any shares of Common Stock held by the undersigned to any bank (each, a “Pledgee”) pursuant to any bona fide pledge to secure indebtedness (a “Pledge”) and any further Pledge of all or any portion of such shares pursuant to any amendments, supplements, modifications, extensions, renewals or restatements of the agreement related to any such Pledge, any refunding or refinancing of the indebtedness secured thereby or any credit facilities that replace, refund or refinance any part of the indebtedness secured thereby, including any such replacement, refunding or refinancing credit facility that increases the amount permitted to be borrowed thereunder or alters the maturity therefor; provided that (x) a copy of the agreement relating to such pledge (a “Pledge Agreement”) shall be provided to the Underwriter, (y) prior to entering into a Pledge Agreement, each Pledgee shall sign an undertaking substantially identical to the undertaking set forth at the conclusion of this agreement, and (z) no filing under the Exchange Act, reporting a reduction in beneficial ownership of shares or an increase in the number of shares subject to a Pledge compared with the number of shares Pledged as of the date of the Prospectus, shall be required or shall be voluntarily made during the Restricted Period by the undersigned or any Pledgee in connection with a Pledge (except if required in the case of a default),]²

provided that in the case of any gift, transfer or distribution pursuant to clause (a), (b), (c), (d) or (e), each donee, transferee or distributee shall sign and deliver an agreement substantially in the form of this letter, and, provided, further, that in the case of any sale, gift, disposition, distribution or other transfer pursuant to clause (b), (c), (d), (e) or (f), no filing under the Exchange Act, reporting a reduction in beneficial ownership of shares of the Company shall be required or shall be voluntarily made during the Restricted Period in connection with any such sale, gift, disposition, distribution or other transfer.

Nothing in this agreement shall prevent the establishment of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act for the transfer of shares of Common Stock, provided that (1) such Plan does not provide for the transfer of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock during the Restricted Period and (2) such a Plan may only be established if no public announcement of the establishment or existence thereof by the undersigned, the Company or any other person acting on behalf of the undersigned or the Company, shall be required nor shall be voluntarily made by the undersigned, the Company or any other person acting on behalf of the undersigned or the Company, prior to the expiration of the Restricted Period.

In addition, the undersigned agrees that, without the prior written consent of the Underwriter, the undersigned will not, during the Restricted Period, 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. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriter are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

This agreement shall terminate automatically upon the termination of the Underwriting Agreement (other than the provisions thereof which survive termination) prior to payment for and delivery of the Common Stock to be sold thereunder.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to the Underwriting Agreement.

[The undersigned acknowledges that if it becomes the beneficial owner (as such term is defined in Rule 13d-3 of the Exchange Act) of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock subject to the terms of this agreement, the undersigned will abide by the terms of this agreement as if it is the signatory thereto.
