ASSET PURCHASE AGREEMENT dated as of , 2017 (this “Agreement”), between Athenex, Inc., a Delaware corporation (“Purchaser”) and Amphastar Pharmaceuticals, Inc., a Delaware corporation (“Seller”).

WHEREAS, pursuant to an asset purchase agreement dated as of March 4, 2016 (the “Hikma Asset Purchase Agreement”), Seller purchased certain assets, including the Transferred Assets (as defined herein), from Hikma Pharmaceuticals PLC, a public limited company incorporated in England and Wales (“Hikma”) (the “Hikma Acquisition”);

WHEREAS, Seller owns the Transferred Assets;

WHEREAS, Seller desires to sell, transfer and deliver the Transferred Assets to Purchaser and Purchaser desires to acquire such Transferred Assets, upon the terms and subject to the conditions of this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual agreements and covenants hereinafter set forth, and intending to be legally bound, the parties hereby agree as follows:

ARTICLE I

PURCHASE AND SALE

SECTION 1.01. Purchase and Sale.

(a) Purchase Price. Upon the terms and subject to the conditions of this Agreement, at the Closing, Seller will sell, transfer, assign, convey and deliver to Purchaser, and Purchaser will purchase, acquire and accept from Seller, all of Seller’s right, title and interest in, to and under the Transferred Assets as of the Closing, free and clear of all Liens (other than Permitted Liens) for (a) an aggregate purchase price of $6.4 million in cash to be paid in accordance with the terms and conditions of Section 2.02(b) (the “Purchase Price”); and (b) the assumption by Purchaser of the Assumed Liabilities. The purchase and sale of the Transferred Assets and the assumption of the Assumed Liabilities are collectively referred to in this Agreement as the “Acquisition”.

(b) Royalty. In addition to the Purchase Price, Purchaser agrees to pay Seller a royalty fee equal to 2% of Net Sales (if any) which are derived from Purchaser’s sales of the Products from the Transferred Assets (the “Royalty Fee”) for a period beginning as of the date of Closing and continuing until the tenth (10^th) anniversary of the Closing Date (the “Royalty Term”). Such Royalty Fee shall be cumulated, will be in U.S. Dollars and paid to Seller within forty-five (45) days of the end of each calendar quarter during the Royalty Term; it being understood that the Royalty Fee payments shall be reconciled, to the extent necessary, in any subsequent quarter during the Royalty Term or at the end of the Royalty Term, as the case may be, based on the actual Net Sales realized by Purchaser. Purchaser shall provide Seller with a written statement setting forth the number of Product units sold and the Royalty Fee due during

each calendar quarter during the Royalty Term within thirty (30) days of the end of each calendar quarter. The Purchaser shall maintain and keep for a period of not less than two (2) years complete and accurate records in sufficient detail to enable any accrued royalties to be calculated. During normal business hours and with reasonable advance written notice but in no event less than twenty (20) Business Days and not exceeding once a year during the Royalty Term, Purchaser shall permit a Representative of Seller to have access to such records of Purchaser as may be necessary to verify the accuracy of the records related to the Royalty Fees paid to Seller (in each case, a “Seller Audit”); provided however that any such Seller Audit must take place no more than one (1) year following the end of the calendar year during the Royalty Term at issue and will be at Seller’s expense unless the mutually agreed upon accounting firm audit finds that the royalties have been under reported by more than 5%, in which case Buyer will pay for the audit. Promptly following Seller’s completion of any such Seller Audit (but in no event later than thirty (30) days following such completion), Seller shall deliver to Purchaser written notice of the results of such Seller Audit, including a description in reasonable detail of any proposed adjustments to the Royalty Fees actually paid to Seller for the applicable period covered by such Seller Audit. Seller and Purchaser will negotiate in good faith to resolve any dispute over Seller’s proposed adjustments to the Royalty Fees, provided that if any such dispute is not resolved within thirty (30) days following receipt by Purchaser of the proposed adjustments, either Purchaser or Seller may engage a mutually agreed upon accounting firm with a national presence (the “Accounting Firm”) on behalf of Purchaser and Seller to resolve any remaining dispute of Seller’s proposed adjustments, which resolution will be final. The Accounting Firm will be instructed to deliver its written determination within thirty (30) days. The Accounting Firm will address only those items in dispute and may not assign a value greater than the greatest value for such item claimed by either party or a value smaller than the smallest value for such item claimed by either party. The fees and expenses of the Accounting Firm will be shared by the parties in inverse proportion to the percentage of the disputed amount determined by the Accounting Firm to be in favor of Seller, on the hand, and Purchaser, on the other hand. The calculation and amount of the Royalty Fees for the period covered by any Seller Audit will become final and binding on all parties upon the earliest of (i) Seller’s delivery of notice to Purchaser of the results of the Seller Audit whereby such results reflect Seller’s agreement with the amount of Royalty Fees actually paid to Seller, (ii) the mutual agreement of Seller and Purchaser with respect to any of Seller’s proposed adjustments to the Royalty Fees actually paid to Seller, and (iii) the Accounting Firm’s final resolution of any disputes submitted to the Accounting Firm. Promptly after such final determination of the amount of the Royalty Fees for the period covered by any Seller Audit: (x) if such finally determined Royalty Fee amount exceeds the amount actually paid to Seller, then Purchaser will pay to Seller an amount equal to such excess within thirty (30) days after such final determination; or (ii) if the amount of Royalty Fees actually paid to Seller exceed such finally determined Royalty Fee amount, then Seller will refund to Purchaser an amount equal to such excess within thirty (30) days after such final determination.

SECTION 1.02. Transferred Assets and Excluded Assets.

(a) The term “Transferred Assets” means all of Seller’s right, title and interest in, to and under the following assets as they exist at the time of the Closing:

(i) all books, records, files, data and other documentation in the categories, to the extent applicable and obtained from Hikma, set forth in Section 1.02(a)(i) of the Seller Disclosure Schedule that are exclusively related to the Products or the Transferred Assets (except to the extent in the possession or control of a Governmental Entity or a contract manufacturer of the Products) and as provided in Section 5.01 (collectively, the “Transferred Books and Records”);

(ii) all ANDAs listed in Section 1.02(a)(ii) of the Seller Disclosure Schedule (the “Regulatory Approvals”); and

(iii) all of the inventory for the Active Pharmaceuticals Ingredients (“API”) as of the Closing listed in Section 1.02(a)(iii) of the Seller Disclosure Schedule.

(b) Notwithstanding anything to the contrary contained in this Agreement, (A) no Excluded Asset (as defined below) shall be included within the Transferred Assets and (B) Seller shall not sell, transfer, assign or deliver to Purchaser, and Purchaser shall not purchase, acquire or accept, any right, title and interest of Seller in, to or under the Commingled Documents or any assets of Seller or its affiliates not expressly included in the Transferred Assets (all such other assets, the “Excluded Assets”); provided, that Seller shall use commercially reasonable efforts to provide Purchaser with access to the Commingled Documents in accordance with Section 5.01.

(c) Subject to Section 5.02(b) and in accordance with Section 5.01, Seller shall have the right to retain copies of and have access to the documents, materials and data relating to the ownership, use, sale, license or lease of the Transferred Assets prior to the Closing Date.

SECTION 1.03. Assumption of Liabilities; Retained Liabilities.

(a) Upon the terms and subject to the conditions of this Agreement Purchaser shall assume, effective as of the Closing, and shall pay, perform and discharge when due, any and all obligations, liabilities and commitments of any nature, whether known or unknown, express or implied, primary or secondary, direct or indirect, liquidated, absolute, accrued, contingent or otherwise and whether due or to become due (collectively, “Liabilities”):

(i) related to or arising out of the ownership, use, sale, license or lease of the Transferred Assets by Purchaser from and after the Closing Date, including all Liabilities (A) related to or arising out of products liability Claims with respect to the Exploitation of any Product on or after the Closing Date or (B) related to or arising out of government seizures, filed corrections, withdrawals or recalls of Product sold on or after the Closing Date;

(ii) concerning the use of any third party Intellectual Property (“IP Liabilities”), arising out of or related to any Exploitation of Product on or after the Closing Date;

(iii) for Transfer Taxes and Apportioned Obligations allocated to Purchaser under Section 5.07; and

(iv) related to or arising out of the matters set forth in Section 1.03(a)(iv) of the Seller Disclosure Schedules.

The Liabilities referenced in clauses (i) through (iv) above are referred to, collectively, as the “Assumed Liabilities”.

(b) The term “Retained Liabilities” means all Liabilities of Seller and its affiliates, including without limitation to the extent related to the Transferred Assets, other than the Assumed Liabilities.

ARTICLE II

CLOSING

SECTION 2.01. Closing. The closing of the Acquisition (the “Closing”) shall take place by the electronic exchange of documents and signature pages on the date hereof (the “Closing Date).”

SECTION 2.02. Transactions To Be Effected at the Closing.

(a) At the Closing, Seller shall deliver or cause to be delivered to Purchaser duly executed binding term sheet, bills of sale, assignments, licenses and other instruments of transfer relating to the Transferred Assets, in each case in the form attached hereto as Exhibit A.

(b) At the Closing, Purchaser shall deliver or cause to be delivered to Seller within fifteen (15) business days of the Closing Date (i) payment, by wire transfer of immediately available funds to one or more accounts designated in writing by Seller (such designation to be made at least fifteen (15) days prior to the Closing Date), of $1.0 million and (ii) duly executed counterparts to the bills of sale, assignments, licenses and other instruments of transfer referred to in Section 2.02(a), and duly executed assumption agreements and other instruments of assumption providing for the assumption of the Assumed Liabilities, in each case reasonably acceptable to Purchaser and Seller. A second payment in the amount of $1.0 million will be made by Purchaser to Seller within 30 days of May 1, 2017. A third payment in the amount of $3.0 million will be paid within 30 days of receiving FDA approval of site transfer to sell Prochlorperazine Edisylate Injection USP and a fourth payment in the amount of $1.4 million will be paid by Purchaser to Seller within 30 days of FDA approval of site transfer of the second product to be FDA approved. If the third and fourth payment milestones are not reached by December 31, 2017, Purchaser will pay the balance of the $4.4 million within 30 days of December 31, 2017. All of the risk of loss with respect to the Transferred Assets (whether or not covered by insurance) shall be on Seller up to the time of the Closing, whereupon such risk of loss with respect to the Transferred Assets shall pass to Purchaser. Notwithstanding anything to the contrary contained in this Agreement except as a result of a breach by Seller or its affiliates

of this Agreement, and/or during the pendency of any disputes arising under or related hereto (whether for breach of contract, tortious conduct or otherwise), in the event that Purchaser fails to make any of the required payments set forth in this Section 2.02(b) (“Payment Breach”), and fails to cure such Payment Breach within 45 days written of notice in accordance with Section 8.04 thereof, Purchaser agrees to transfer the ownership of the Transferred Assets to Seller and Purchaser shall have no right of recourse to any of the previous payments.

Except as expressly set forth in any representation or warranty in Article III, Purchaser acknowledges and agrees that no person, including the Purchaser Indemnitees, shall have any claim (whether in warranty, contract, tort (including negligence or strict liability) or otherwise) or right to indemnification pursuant to Article VII (or otherwise) with respect to any information, documents or materials made available or otherwise furnished to or for Purchaser, its affiliates or their respective Representatives by Seller, Hikma, any of their respective affiliates, or any of their respective Representatives, including any financial projections or other statements regarding future performance and any other information, documents or material, whether oral or written, made available to Purchaser, its affiliates or their respective Representatives in any “data room,” management presentation, “break-out” discussions or meetings, responses to questions submitted on behalf of Purchaser, its affiliates or their respective Representatives or otherwise furnished to Purchaser, its affiliates or their respective Representatives in any form in expectation of the transactions contemplated hereby, except, for avoidance of doubt, insofar as such claim or indemnification relates to a Retained Liability or an Excluded Asset.

Further, Purchaser acknowledges that there are uncertainties inherent in attempting to make such estimates, projections, forecasts, plans and budgets, that Purchaser is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to it, its affiliates or their respective Representatives (including the reasonableness of the assumptions underlying such estimates, projections, forecasts, plans and budgets) and that Purchaser is not relying on, and Seller and its affiliates have not made and are not making any representations or warranties with respect to, any estimates, projections, forecasts, plans or budgets made available or otherwise furnished by Seller, Hikma, their respective affiliates or their respective Representatives, and Purchaser shall not, and shall cause its affiliates and their respective Representatives not to, hold any such person liable with respect thereto (whether in warranty, contract, tort (including negligence or strict liability) or otherwise).

(d) Purchaser, its affiliates and their respective Representatives acknowledge that any dispute regarding Section 3.08 (API), Seller reserves the right to perform its own API testing.

Any such access shall be subject to confidentiality restrictions equivalent to those set forth in Section 5.02. In the event that Purchaser exercises its right to access Commingled Documents hereunder, Purchaser shall assume all liability for any disclosure or use of the information other than Purchaser Commingled Information (such other information, the “Seller Commingled Information”) contained therein and any and all loss, damage, destruction or alteration of such Commingled Documents arising from the use or possession of such Commingled Documents by Purchaser or its Representatives. For clarity, this Section 5.01 shall not provide either party hereto or any of their respective affiliates with any rights to use or disclose any information contained within any Commingled Documents not otherwise retained or obtained pursuant to this Agreement. All requests by Purchaser for Commingled Documents shall be directed in writing to the persons set forth in Section 5.01(iv) of the Seller Disclosure Schedule (or such other persons as are designated by Seller in writing to Purchaser).

(II) Any language in this Section 5.01 to the contrary notwithstanding, in all events, Seller shall be obligated to provide to Purchaser, as soon as practicable following the Closing Date, copies of (i) Regulatory Approvals, and (ii) Commingled Documents (including Purchaser Commingled Information), that actually are in possession of Seller as of the Closing Date, in each case redacted to exclude all Third Party Information.

SECTION 5.02. Confidentiality.

(a) Purchaser acknowledges that the information provided to it in connection with the Acquisition and the consummation of the other transactions contemplated by this Agreement is subject to the terms of confidentiality letter agreement between Purchaser and Seller in connection with the Acquisition, dated September 1, 2016 (the “Confidentiality Agreement”). Effective upon, and only upon, the Closing, the Confidentiality Agreement shall terminate with respect to information relating solely to the Transferred Assets or the Assumed Liabilities; provided, however, that Purchaser acknowledges that any and all other information provided to it by any of Seller, any of its affiliates or their respective Representatives concerning Seller or any of its affiliates (other than information to the extent relating to the Transferred Assets or the Assumed Liabilities) shall remain subject to the terms and conditions of the Confidentiality Agreement after the Closing.

(b) Subject to Section 5.03, from and after the Closing until the third anniversary of the Closing Date, Seller shall, and shall cause its affiliates to, treat as confidential and shall

safeguard any and all confidential or proprietary information, knowledge and data related solely to the Transferred Assets or the Assumed Liabilities by using the same degree of care to prevent the unauthorized use, dissemination or disclosure of such information, knowledge and data as Seller and its affiliates used with respect thereto prior to the execution of this Agreement; provided, however, that Seller and its affiliates shall be entitled to use any such information, knowledge and data only to the extent necessary to perform their respective obligations or exercise or enforce their respective rights and remedies under this Agreement, any Ancillary Agreement or any agreements entered into in connection with any of the foregoing. The obligations of Seller and its affiliates pursuant to this Section 5.02(b) shall not extend to any information, knowledge or data that is (i) required to be disclosed by applicable Law, (ii) requested by a government official or (iii) except as a result of a disclosure by Seller or its affiliates after the Closing in breach of this Agreement, generally available to the public or already known by a third party receiving such information from Seller or its affiliates.

SECTION 5.03. Publicity. Other than any press release, if any, to be agreed to in writing by Purchaser and Seller to be issued following the execution of this Agreement, neither of Purchaser, on the one hand, nor Seller, on the other hand, will issue or permit any of its respective affiliates to issue any press release, website posting or other public announcement with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other party (which consent shall, if applicable, be provided as promptly as practicable), except as may be required by Law or stock exchange rules or regulations (in which case, whichever of Purchaser or its affiliates or Seller or its affiliates, as applicable, is required to make the release or statement shall, to the extent compliance with such Law, rules or regulations permits, allow the other reasonable time to comment on such release or statement in advance of such issuance and such other party shall provide any comments thereto as promptly as practicable); provided, however, that (a) Purchaser, on the one hand, and Seller, on the other hand, may, following the date hereof, make internal announcements to their respective employees and affiliates that are consistent with the parties’ prior permitted public disclosures regarding the transactions contemplated by this Agreement and (b) Seller and Purchaser may communicate with government officials, customers and suppliers regarding this Agreement and the transactions contemplated hereby (so long as, in the case of customers and suppliers, such communications are consistent with Seller’s or Purchaser’s, as applicable, prior permitted public disclosures regarding the transactions contemplated by this Agreement, or a communications plan agreed upon by Seller and Purchaser).

SECTION 5.04. Covenant Not to ▇▇▇. Seller agrees not to object, oppose or otherwise challenge the use, in connection with the Exploitation of the Products anywhere in the world, by Purchaser and its successors, assigns, sublicensees, contractors, manufacturers, agents and representatives of all Know-How that is controlled by Seller and its affiliates as of the Closing.

SECTION 5.05. Insurance. From and after the Closing, Purchaser shall not, and shall cause its affiliates not to, assert any claim against any insurance policies or practices of Seller and its affiliates or Hikma and its affiliates (including any captive insurance policies,

self-insurance, surety bonds or corporate insurance policies or practices). Purchaser agrees, from and after the Closing Date, to arrange for its own insurance policies with respect to the Transferred Assets and the Assumed Liabilities covering all periods and agrees not to seek, through any means, to benefit from any of Seller’s or its affiliates’ insurance policies which may provide coverage for claims relating in any way to the Transferred Assets or the Assumed Liabilities.

SECTION 5.06. Change in Ownership Letters. Purchaser and Seller shall, with respect to each Regulatory Approval, if applicable, file each Purchaser Change in Ownership Letter and each Seller Change in Ownership Letter, respectively, with the U.S. Food and Drug Administration (the “FDA”) as soon as possible and in any event within 10 days after the date on which Seller provides to Purchaser a copy of the applicable Regulatory Approval underlying each such letter pursuant to and in accordance with Section 5.01. The letters filed by Seller and Purchaser pursuant to this Section 5.06 shall comply with all aspects of 21 C.F.R. 314.72 (Change in Ownership of an Application), and such letters shall provide for transfer of title to the Regulatory Approvals for the Products to be effective as of the Closing.

SECTION 5.07. Tax Covenants.

(a) As soon as practicable after the Closing, the parties shall agree upon an allocation of the Purchase Price (plus the Assumed Liabilities, to the extent properly taken into account under Section 1060 of the Internal Revenue Code of 1986, as amended) among the Transferred Assets in accordance with Section 1060 of the Internal Revenue Code of 1986, as amended. Seller and Purchaser shall, and shall cause their respective affiliates to, act in accordance with such allocation in the preparation, filing and audit of any Tax Return.

(b) Purchaser and Seller shall cooperate in timely making all filings, returns, reports and forms as may be required in connection with Purchaser’s payment of Transfer Taxes.

Purchaser and Seller shall each pay fifty percent (50%) of all Transfer Taxes.

(c) All real property Taxes, personal property Taxes and similar ad valorem obligations levied with respect to the Transferred Assets for a taxable period which includes (but does not end on) the Closing Date (collectively, the “Apportioned Obligations”) shall be apportioned between Seller, on the one hand, and Purchaser, on the other hand, based on the number of days of such taxable period included in the Pre-Closing Tax Period and the number of days included in the Post-Closing Tax Period. Seller shall be liable for the proportionate amount of such Taxes that is attributable to the Pre-Closing Tax Period and Purchaser shall be liable for the proportionate amount of such Taxes that is attributable to the Post-Closing Tax Period.

(d) Purchaser agrees to retain all records relating to Taxes with respect to the Transferred Assets for all taxable periods ending on or prior to the Closing Date until the expiration of the statutes of limitation (including any extensions thereof) for the taxable period or periods to which such records relate. Purchaser and Seller agree to provide each other with such information and assistance as is reasonably necessary, including access to records and personnel, for the preparation of any Tax Returns or for the defense of any Tax claim or assessment, whether in connection with an audit or otherwise.

Subject to this Article VII, from and after the Closing, Seller shall indemnify Purchaser and its affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives (the “Purchaser Indemnitees”) from and against any and all losses, damages or expenses, including reasonable third-party legal fees and expenses in connection with any Proceeding (collectively, “Losses”), to the extent arising or resulting from any of the following:

(a) any breach of any Specified Representations and any representations and warranties set forth in Section 3.06 (Regulatory Approvals; Compliance Arrangements), Section 3.07 (Hikma Purchase Agreement) and Section 3.08 (API);

(b) any breach of any covenant of Seller contained in this Agreement;

(d) any Retained Liability.

SECTION 7.02. Indemnification by Purchaser. Subject to this Article VII, from and after the Closing, Purchaser shall indemnify Seller and its affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives (the “Seller Indemnitees”) from and against any and all Losses, to the extent arising or resulting from any of the following:

(a) any breach of any representation or warranty of Purchaser contained in this Agreement;

(b) any breach of any covenant of Purchaser contained in this Agreement;

(d) the Exploitation of the Products following the Closing.

SECTION 7.03. Indemnification Procedures.

(a) Third Party Claims. If any party (the “Indemnified Party”) receives written notice of the commencement of any Proceeding or the assertion of any claim by a third party or the imposition of any penalty or assessment (in each case other than with respect to Taxes) for which indemnity may be sought under Section 7.01 or Section 7.02 (a “Third Party Claim”), and such Indemnified Party intends to seek indemnity pursuant to this Article VII, the Indemnified Party shall promptly (but no later than 30 days of receiving such notice) provide the other party (the “Indemnifying Party”) with written notice of such Third Party Claim, stating the nature, basis, the amount (to the extent known or estimated, which amount shall not be conclusive of the final amount of such Third Party Claim) and a reasonable description of any other material details thereof. Failure of the Indemnified Party to give such notice will not relieve the Indemnifying Party from its indemnification obligations hereunder, except to the extent that the Indemnifying Party is actually prejudiced thereby. The Indemnifying Party will have 20 days from receipt of any such notice of a Third Party Claim to give notice to the Indemnified Party whether it is assuming and controlling the defense, appeal or settlement proceedings thereof with counsel of the Indemnifying Party’s choice; provided, however, that the Indemnifying Party shall not have the right to assume the defense of any Third Party Claim to the extent (but only to the extent) such Third Party Claim (i) relates to any actual or alleged criminal proceeding, action, indictment, allegation or investigation or (ii) seeks an injunction or equitable relief against the Indemnified Party that is not merely ancillary to the principal damages sought in the relevant claim. So long as the Indemnifying Party or the Indemnified Party, as applicable, has assumed the defense, appeal or settlement proceedings of the Third Party Claim in accordance herewith, (1) the other such party may retain separate co-counsel at the controlling party’s cost and expense and participate in (but not control) the defense, appeal or settlement proceedings of the Third Party Claim, (2) the controlling party will not admit any liability, file any papers or consent to the entry of any judgment or enter into any settlement agreement, compromise or discharge with respect to the Third Party Claim without the prior written consent of the other such party and (3) the controlling party will not admit to any wrongdoing by the other such party. The controlling party shall have the right to settle any Third Party Claim for which it obtains a full release of the other such party with respect to such Third Party Claim or to which settlement the Indemnified Party consents in writing (such consent not to be unreasonably withheld, conditioned or delayed). The parties will act in good faith in responding to, defending against, settling or otherwise dealing with Third Party Claims. The parties will also cooperate in any such defense, appeal or settlement proceedings, and give each other reasonable access to all

information relevant thereto. Whether or not the Indemnifying Party has assumed the defense, appeal or settlement proceedings with respect to a Third Party Claim, such Indemnifying Party will not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into or any judgment that was consented to without the Indemnifying Party’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed). The party assuming such defense, appeal or settlement proceedings shall keep the other party reasonably advised of the status of such Third Party Claim and the defense thereof and shall reasonably consider recommendations made by the other party with respect thereto.

(b) Other Claims. An Indemnified Party shall give the Indemnifying Party written notice of any matter that an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 30 days of such determination, stating the amount of the Loss, if known, and the method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises. It is the express intention of the parties that the indemnification provided for in this Article VII shall apply to direct claims between the parties for a breach of this Agreement (whether or not involving a third party).

SECTION 7.04. Limitations on Indemnification. Notwithstanding anything to the contrary contained in this Agreement, (i) Seller’s aggregate maximum liability under Section 7.01(a) shall not exceed an amount equal to the Purchase Price with exception of Section 3.08 (API), Seller’s aggregate maximum liability under 3.08 (API) shall not exceed $612,000; (ii) no party shall have any liability for an otherwise indemnifiable Loss that is contingent unless and until such contingent Loss becomes an actual Loss of the Indemnified Party and is due and payable, so long as the claim for such Loss was timely submitted pursuant to the provisions of this Article VII; (iii) no party shall be liable for any Losses to the extent the Purchaser Indemnitees or the Seller Indemnitees, as applicable, failed to mitigate such Losses in accordance with applicable Laws; (iv) no party shall be liable for any Loss to the extent arising from any Law not in force on the date hereof or any change in Law which takes effect retroactively and (v) no party shall be liable for any otherwise indemnifiable Loss arising out of any breach of any representation, warranty, covenant or agreement of such party unless a claim therefor is asserted with specificity and in writing by the Indemnified Party timely in accordance with Section 7.08, failing which such claim shall be waived and extinguished. The waiver of any condition to the Closing based on the accuracy of any representation or warranty or on the performance of or compliance with any covenant or agreement shall be deemed a waiver of the right to indemnification under this Article VII with respect to such representation or warranty, covenant, agreement or obligation. Notwithstanding any implication to the contrary contained in this Agreement, the limits on indemnification set forth in this Agreement shall not apply to any claims or Losses based on fraud or intentional misrepresentation.

SECTION 7.05. Calculation of Indemnity Payments.

(a) The amount of any Loss for which indemnification is provided under this Article VII shall be net of any amounts actually recovered by the Indemnified Party with respect to such

Loss (including payments under insurance policies net of all increases in premiums and other costs of such insurance policies for pursuing a claim thereunder). For Section 3.08 (API), calculation of loss is based on the quantity of APIs that is unusable, which is unexpired as of the Testing Date, with payment of $0.48 per grams for Acyclovir and $25.50 per gram for Prochlorperazine Edisylate.

(b) If an Indemnified Party recovers an amount from a third party (including payments under insurance policies) in respect of Losses that are the subject of indemnification hereunder after all or a portion of such Losses have been paid by an Indemnifying Party pursuant to this Article VII, then the Indemnified Party shall promptly remit to the Indemnifying Party the amount received by the Indemnified Party in respect thereof (up to the amount paid by the Indemnifying Party in respect of such Losses but net of any increase in premiums paid or other costs incurred in connection with the recovery of such proceeds).

(c) Each party shall, and shall cause its respective affiliates to, take all commercially reasonable steps to mitigate any Loss indemnifiable hereunder upon and after becoming aware of any event that could reasonably be expected to give rise to any Loss. No party shall be entitled to any payment, adjustment or indemnification more than once with respect to the same matter.

SECTION 7.06. Exclusive Remedy. From and after the Closing, subject to Section 1.01(b) and Section 8.15, Purchaser’s sole and exclusive remedy with respect to any and all claims relating to this Agreement, the Transferred Assets, the Assumed Liabilities or the transactions contemplated by this Agreement shall be pursuant to the indemnification provisions set forth in this Article VII. In furtherance of the foregoing, Purchaser hereby waives, from and after the Closing, any and all rights, claims and causes of action whether based on warranty, in contract, in tort (including negligence or strict liability) or otherwise that Purchaser or any other Purchaser Indemnitee may have against Seller, any of its affiliates or any other person, arising under or based upon any Law, except pursuant to the indemnification provisions set forth in this Article VII. Notwithstanding anything to the contrary contained in this Agreement, no breach of any representation, warranty, covenant or agreement contained herein shall, after the consummation of the transactions contemplated by this Agreement, give rise to any right on the part of Purchaser, on the one hand, or Seller, on the other hand, to rescind this Agreement or any of the transactions contemplated hereby. No past, present or future Representative, incorporator, member, partner or stockholder of Seller or any of its affiliates shall have any liability, whether based on warranty, in contract, in tort (including negligence or strict liability) or otherwise, for any obligations or liabilities of Seller or any of its affiliates arising under, in connection with or related to this Agreement or for any claim based on, in respect of or by reason of the Acquisition, including any alleged non-disclosure or misrepresentations made by any such persons. Notwithstanding anything to the contrary contained in this Agreement, nothing in this Agreement shall limit the rights, remedies or claims of any party based on fraud or intentional misrepresentation by any other party.

SECTION 7.07. Tax Treatment of Indemnification. For all Tax purposes, Purchaser and Seller agree to treat any adjustments to amounts paid under this Agreement and any indemnity payment under this Agreement as an adjustment to the Purchase Price unless a final determination of a Taxing Authority (which shall include the execution of an IRS Form 870-AD or successor form or an HMRC Enquiry Closure Notice form) provides otherwise.

SECTION 7.08. Survival. All representations and warranties contained in this Agreement, and all claims with respect thereto shall terminate at Closing; provided, however, that (i) Seller’s representations and warranties set forth in Section 3.06 (Regulatory Approvals; Compliance Arrangements), Section 3.07 (Hikma Asset Purchase Agreement), Section 3.08 (API) shall terminate at the close of business on the date that is one year following the Closing Date, and (ii) the Specified Representations and the representations and warranties set forth in Section 4.01 (Organization), Section 4.03 (Authority; Execution and Delivery; Enforceability) and Section 4.05 (Brokers and Finders), shall survive indefinitely; provided, further that the covenants or agreements contained in this Agreement which by their terms contemplate performance after the Closing Date shall survive the Closing only until the expiration of the term of the undertaking set forth in such agreements and covenants. After the Closing, no party shall have any liability or obligation of any nature with respect to any representation, warranty, agreement or covenant after the termination thereof, with the exception of payment of the Purchase Price, unless a notice of a breach thereof giving rise to a right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time, in which case the representation, warranty, covenant or agreement which is the subject of such claim shall survive, to the extent of the claims described in the notice only, until such claim is resolved, whether or not the amount of the Losses resulting from such breach has been finally determined at the time the notice is given.

SECTION 7.09. No Setoff Rights. Neither party shall have any right of setoff of any amounts due and payable, or any Liabilities arising, under this Agreement, any Ancillary Agreement or any other agreement entered into by the parties or their respective affiliates against any other amounts due and payable, or any other Liabilities arising, under this Agreement, any Ancillary Agreement or any other agreement entered into by the parties or their respective affiliates. The payment obligations under each of this Agreement and the Ancillary Agreements remain independent obligations of each party, irrespective of any amounts owed to any other party under this Agreement, the respective Ancillary Agreements or any other agreement entered into by the parties or their respective affiliates.
