9.(a) The Company agrees to indemnify and hold harmless the Placement Agent, its affiliates, directors, officers and employees and each person, if any, who controls the Placement Agent within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, or 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, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, any preliminary prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, or any Issuer Free Writing Prospectus in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of the Placement Agent expressly for use therein, it being understood and agreed that the only such information furnished by the Placement Agent is the information described as such in Section 9(b) below.

(b) The Placement Agent agrees to indemnify and hold harmless the Company, each of the directors of the Company and each of the officers of the Company who shall have signed the Registration Statement against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in

settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any post-effective amendment thereof, or 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, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Pricing Disclosure Package or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of the Placement Agent expressly for use therein, it being understood and agreed that the only such information furnished by the Placement Agent consists of the third sentence of the second paragraph under the heading “Plan of Distribution” in the Pricing Prospectus and the Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 9 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 Section, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 9). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and jointly with any other indemnifying party similarly notified, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party). Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events the reasonable fees and expenses of such counsel shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or

circumstances, which counsel, in the event of indemnified parties under Section 9(a), shall be selected by the Placement Agent. 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 this Section 9 in respect of any losses, liabilities, claims, damages or expenses (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, liabilities, claims, damages or expenses (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 Placement Agent on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, 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 such relative benefits but also the relative fault of the Company on the one hand and the Placement Agent on the other in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses (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 Placement Agent on the other from the offering of the Shares 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 Placement Fee received by the Placement Agent, in each case as set forth in the table on the cover page of the Prospectus. 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 Placement Agent 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 Placement Agent agree that it would not be just and equitable if contributions pursuant to this Section 9(d) were determined by pro rata allocation (even if the Placement Agent was 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 Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section 9(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 Section 9(d), the Placement Agent shall not be required to contribute any amount in excess of the Placement Fee.

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.

(e) The obligations of the parties to this Agreements contained in this Section 9 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.

10.Reserved.

11.Notwithstanding anything herein contained, this Agreement may be terminated, subject to the provisions of Section 12, in the absolute discretion of the Placement Agent, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally on the NYSE MKT, the New York Stock Exchange or on the NASDAQ Global Select Market or the NASDAQ Global Market shall have been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental or regulatory authority, (b) trading of any securities of or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market, (c) a general moratorium on commercial banking activities in New York shall have been declared by Federal or New York State authorities or a new restriction materially adversely affecting the distribution of the Shares, shall have become effective, or (d) there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Placement Agent, impracticable to market the Shares to be delivered on the Closing Date, or to enforce contracts for the sale of the Shares.

If this Agreement is terminated pursuant to this Section 11, such termination will be without liability of any party to any other party except as provided in Section 12 hereof.

12.The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Placement Agent set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Placement Agent, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Section 8 or 11 or if for any reason the purchase of any of the Shares by the Investors is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 7, the respective obligations of the Company and the Placement Agent pursuant to Section 9 and the provisions of Sections 12, 13 and 16 shall remain in effect and, if any Shares have been purchased under the Securities Purchase Agreement the representations and warranties in Section 1 and all obligations under Section 5 and Section 6 shall also remain in effect. If this Agreement shall be terminated by the Placement Agent, or any of them, under Section 8 or otherwise because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of

the conditions of this Agreement (other than solely by reason of the failure of the Placement Agent to perform its obligations hereunder), or if for any reason the Company shall be unable to perform its obligations under this Agreement (other than solely by reason of the failure of the Placement Agent to perform its obligations hereunder) or any condition of the Placement Agent’s obligations cannot be fulfilled, the Company agrees to reimburse the Placement Agent for all out-of-pocket expenses (including the fees and expenses of its counsel) reasonably incurred by the Placement Agent in connection with this Agreement or the offering contemplated hereunder.

13.This Agreement shall inure to the benefit of and be binding upon the Company and the Placement Agent, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.

14.All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by any standard form of telecommunication. Notices to the Placement Agent shall be given to c/o c/o Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, XX 00000 (fax no.: (000) 000-0000), Attention: Syndicate Registration, with a copy, in the case of any notice pursuant to Section 9, to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000; with a copy to Xxxxxxxxx & Xxxxxxx LLP, 000 Xxxxxx Xxxxxx, Xxx Xxxx, XX, 00000 (fax no: 000.000.0000), Attention: Xxx Xxxxxx.

15.This Agreement may be signed in counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument.

16.THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO SUCH STATE’S PRINCIPLES OF CONFLICTS OF LAWS.

17.The parties hereby submit to the jurisdiction of and venue in the federal courts located in the City of New York, New York in connection with any dispute related to this Agreement, any transaction contemplated hereby, or any other matter contemplated hereby.

Placement Agent 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 Placement Agent 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.

19.The Company acknowledges that the Placement Agent’s research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Placement Agent’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Placement Agent with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by the Placement Agent’s investment banking divisions. The Company acknowledges that each of the Placement Agent is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transaction for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

Ladies and Gentlemen:

The undersigned refers to the proposed Placement Agency Agreement (the “Placement Agency Agreement”) by and between Aratana Therapeutics, Inc., a Delaware corporation (the “Company”), and Barclays Capital Inc.

For purposes of this Agreement, “immediate family member” shall mean any relation by blood, marriage or adoption, not more remote than first cousin.

The foregoing restrictions shall not apply to (a) bona fide gifts by the undersigned, (b) the surrender or forfeiture of shares of Common Stock to the Company to satisfy tax withholding obligations upon exercise or vesting of stock options or equity awards or in connection with the “cashless” exercise of options to purchase shares of Common Stock or in connection with the “net exercise” of warrants; (c) transfers of Common Stock or any security convertible into or exercisable for Common Stock to an immediate family member, an immediate family member of a domestic

partner or a trust for the benefit of the undersigned, a domestic partner or an immediate family member or to any corporation, partnership, limited liability company or other entity all of the beneficial ownership interests of which are held exclusively by the undersigned, a domestic partner and/or one or more family members of the undersigned or the undersigned’s domestic partner in a transaction not involving a disposition for value, (d) transfers of Common Stock or any security convertible into or exercisable for Common Stock upon death by will or intestate succession, (e) the exercise of any option, warrant or other right to acquire shares of Common Stock, the settlement of any stock-settled stock appreciation rights, restricted stock or restricted stock units, or the conversion of any convertible security into securities of the Company, (f) securities transferred to one or more affiliates of the undersigned and distributions of securities to partners, members or stockholders of the undersigned, (g) transactions relating to securities acquired in open market transactions after the Offering Date, (h) sales or transfers of Common Stock made pursuant to a trading plan established pursuant to Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”) that has been entered into by the undersigned and provided or made available to the Placement Agent prior to the date of this Agreement and (i) the entry into any trading plan established pursuant to Rule 10b5-1, provided that such plan does not provide for any sales or other dispositions of Common Stock during the Lock-Up Period; provided that, (1) in the case of a transfer or distribution pursuant to the preceding clauses (f), (g) or (i), prior to the expiration of the Lock-up Period, no public disclosure or filing under the Exchange Act by any party to the transfer (donor, donee, transferor or transferee) shall be required, or made voluntarily, reporting a reduction in beneficial ownership of Common Stock in connection with such transfer and (2) in the case of a transfer or distribution pursuant to the preceding clauses (a), (c), (d) or (f), each resulting transferee of the Company’s securities agrees in writing prior to such transfer to be bound by the terms of this Agreement as if it were a party hereto.

In addition, the undersigned agrees that, during the Lock-Up Period, without the prior written consent of the Placement Agent (which consent may be withheld in their sole discretion): (a) the undersigned will not request, make any demand for or exercise any right with respect to, the registration of any Common Stock or any security convertible into or exercisable or exchangeable for Common Stock, and (b) the undersigned waives any and all notice requirements and rights with respect to the registration of any such security pursuant to any agreement, understanding or otherwise to which the undersigned is a party. In addition, the undersigned hereby waives any and all preemptive rights, participation rights, resale rights, rights of first refusal and similar rights that the undersigned may have in connection with the offering contemplated by the Placement Agency Agreement or with any issuance or sale by the Company of any equity or other securities before such offering.

Any Common Stock received upon exercise of options, warrants or any securities convertible into or exchangeable or exercisable for Common Stock granted to the undersigned will also be subject to this Agreement.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to (a) decline to make any transfer of shares of Common Stock if such transfer would constitute a violation or breach of this Agreement and (b) place legends and stop transfer instructions on any such shares of Common Stock owned or beneficially owned by the undersigned.

This Agreement is irrevocable and shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to choice of law rules. This Agreement shall lapse and become null and void (a) if the Offering Date shall not have occurred on or before the earliest of (i) such time as the Placement Agent, on the one hand, or the Company, on the other hand, advises the other in writing, prior to the execution of the Placement Agency Agreement that it has determined not to proceed with the Offering, (ii) termination of the Placement Agency Agreement or (iii) on May 10, 2017, in the event the Placement Agency Agreement has not been executed by that date (provided, however, that the Company may from time to time extend such termination date by up to an aggregate of three months with written notice to the undersigned prior thereto).

2.2 Representations and Warranties of Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as of the date hereof and as of the date of the Closing to the Company as follows:

(a) Organization; Authority. If Purchaser is not a natural person, such Purchaser is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with full right, corporate, limited liability or partnership power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder. The execution, delivery and performance by Purchaser of the transactions contemplated by this Agreement has been duly authorized by all necessary corporate or similar action on the part of Purchaser. This Agreement to which it is a party has been duly executed by Purchaser, and when delivered by Purchaser in accordance with the terms hereof, will constitute the valid and legally binding obligation of Purchaser, enforceable against it in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

(b) Information; Confidentiality. Purchaser and its advisors, if any, have been furnished with all publicly available materials relating to the business, finances and operations of the Company and such other publicly available materials relating to the offer and sale of the Shares as have been requested by Purchaser. Purchaser and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by Purchaser or its advisors, if any, or its representatives shall modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained herein. Purchaser understands that its investment in the Shares involves a high degree of risk. Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Shares. Other than to other persons party to this Agreement or to such Purchaser’s representatives, including, without limitation, its officers, directors, partners, legal and other advisors, employees, agents and affiliates, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

(c) No Governmental Review. Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the investment in the Shares, nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

(d) Sales; Short Selling. From and after the date Purchaser received any information about the existence of this offering, Purchaser has not offered, pledged, sold, contracted to sell, sold any option or contract to purchase, purchased any option or contract to sell, granted any option, right or warrant to purchase, loaned, or otherwise transferred or disposed of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, entered 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, or directly or indirectly, through related parties, affiliates or otherwise sold “short” or “short against the box” (as those terms are generally understood) any equity security of the Company. Purchaser covenants that it will not, nor will it authorize or permit any person acting on its behalf to, engage in any such transactions until following the Closing.

(e) Information Regarding Purchaser. Purchaser has provided the Company with true, complete, and correct information regarding all applicable items with respect to such Purchaser on Schedule A to this Agreement.

(f) Placement Agents as Beneficiaries. Purchaser expressly acknowledges and agrees that all representations, warranties, covenants and agreements made or given by the Purchaser to the Company herein, are also irrevocably made and given for the benefit of the Placement Agent and that the Placement Agent is entitled to rely on the same in connection with the placement of the Shares as if such representations, warranties, covenants and agreements, as applicable, were made directly to the Placement Agent.

(g) Non-Reliance on Placement Agents. Purchaser understands that the Placement Agent has acted solely as the agent of the Company in this placement of the Shares and not to the

Purchaser. Purchaser further acknowledges that (i) the Placement Agent, its affiliates, and its respective representatives make no representation or warranty with regard to the merits of the offering of the Shares or as to the completeness or accuracy of any information or materials such Purchaser may have received in connection therewith, and Purchaser has not relied and will not rely on any information, representations or advice furnished by or on behalf of any of the Placement Agent, its affiliates or its respective representatives, orally or in writing, in making a decision to purchase the Shares, (ii) it will be responsible for conducting its own due diligence investigation with respect to the Company and the offer and sale of the Shares, (iii) it will be purchasing Shares based on the results of its own due diligence investigation of the Company and (iv) it has negotiated the offer and sale of the Shares directly with the Company, and the Placement Agent will not be responsible for the ultimate success of any such investment.
