by such Regulatory Authority concerning the safety of the Product, then the Seller shall notify the Buyer and provide the Buyer with copies of such written or electronic correspondence as soon as practicable, but not later than five (5) Business Days after receipt of such correspondence. Unless otherwise prevented by an applicable Legal Requirement, Seller shall provide Buyer with a copy of any written response hereto in advance (in light of the prevailing circumstances) of submitting such response to the applicable Regulatory Authorities.

(c)           From and after the Closing, Buyer shall be solely and exclusively responsible for conducting, handling or processing all voluntary and involuntary recalls of units of Product, including recalls required by any Governmental Body, with respect to the Product, regardless of whether the Product was sold before or after the Closing, subject to Seller’s financial responsibility for Seller Finished Product.

(e)           Following the Closing Date, other than with respect to Remaining Lot 18 Product, Buyer shall not label any Product with Seller’s NDC number without first obtaining the prior written consent of Seller.

(f)            Seller shall have the final authority and responsibility for final release of any Product bearing Seller’s NDC number. Buyer shall not market, sell or distribute Product bearing Seller’s NDC number prior to receipt of Seller’s written release of each quantity, batch, lot or shipment (or part thereof) of such Product.

(g)           While Buyer remains solely responsible for regulatory compliance relating to the Product following the Closing Date, during the time that the Product bears Seller’s name or NDC Number on the Product label or the Seller’s name is included on any written, printed, or graphic materials which reference the Product, Buyer must notify Seller, in writing, within twenty-four (24) hours of any inquiry or inspection by a Governmental Body that relates to the Product.

The Parties will notify all customers of the foregoing change in trade return procedures no less than ten (10) Business Days prior to the end of the “Service Period” (as defined in the Transition Services Agreement). The Parties will work together in good faith to mutually agree on the form and content of such customer notice.

(b)           Solely for purposes of this Section 5.3, the term “Seller Finished Product” shall be deemed to exclude Lot 18 Product. For clarity, all other uses of, and/or references to, Seller Finished Product throughout this Agreement shall include Lot 18 Product. From and after the Closing Date, Buyer shall be financially responsible for all returns of Finished Product, other than returns of Seller Finished Product, and, shall cause its processor to process trade returns in accordance with Buyer’s normal returns procedures. Accordingly, Seller will provide to Buyer an invoice for all out-of-pocket costs actually incurred by Seller and its Affiliates with respect to returns of any Finished Product following the Closing Date (including amounts paid or credited by Seller and its Affiliates for such returns according to Seller’s standard returned goods policy), and Buyer will pay Seller such amount within thirty (30) days of receipt of such invoice.

Accordingly, Buyer will provide to Seller an invoice for all out-of-pocket costs actually incurred, without markup, by Buyer and its Affiliates with respect to returns of any Seller Finished Product (including amounts paid or credited by Buyer and its Affiliates for such returns according to Buyer’s standard returned goods policy), and Seller will pay Buyer such amount within thirty (30) days of receipt of such invoice.

(c)           For any Finished Product that is returned to one Party but is the processing responsibility of the other Party pursuant to Section 5.3(a), the Party receiving such returned Finished Product will destroy, or cause to be destroyed, all such Finished Product. Each of Buyer and Seller shall destroy, or cause to be destroyed, all such returned Finished Product in a manner consistent with all Legal Requirements, and the costs of such destruction shall be reimbursed by the Party with processing responsibility for such Finished Product pursuant to Section 5.3(a).

(d)           From and after the Closing Date until the expiration date of the last lot of Seller Finished Product, for any Finished Product that is returned to one Party but is the processing responsibility of the other Party, the processing Party will, upon request, provide the other Party with a written report setting out all of the data elements listed in Schedule 5.3(d) (each a “Returns Report”) within ten (10) days of the request, and such returns shall be processed according to the processing Party’s then-current returned goods policy, which shall be commercially reasonable. For the avoidance of doubt, in the case of a customer dispute, the return quantities as listed on the Returns Report shall be considered final.

(e)           Neither Buyer nor Seller shall instruct, recommend or attempt to induce customers who have previously purchased any Finished Product from it to (i) return such Finished Product when that would not otherwise have been the case but for such Party’s instructions, recommendations or inducement or (ii) delay the return of such Finished Product.

5.4 Governmental Price Reporting.

(a)           “Governmental Price Reports” means (1) any and all data required to be reported relating to the Product under the Medicaid drug rebate program, including without limitation the Average Manufacturer Price (as defined at 42 U.S.C. § 1396r-8(k)(1)) (“AMP”) and the Best Price (as defined at 42 U.S.C. § 1396r-8(c)(1)(C)) and (2) any and all data required to be reported relating to the Product(s) under state drug price reporting requirements. “PHS Price Reports” means any and all data required to be reported relating to the Product under a Pharmaceutical Pricing Agreement under section 340B of the Public Health Service (“PHS”) Act, 42 U.S.C. 256b.

All pricing data furnished by Seller pursuant to this subsection shall be provided in the same format that such data are provided by Seller to CMS in connection with Seller’s own Governmental Price Reports, or in a format otherwise mutually agreed upon by the Parties. For pricing and sales data that are required in order to submit Governmental Price Reports, but that are not themselves provided to the CMS, Seller will furnish that data in a format mutually agreed upon by the Parties. Without limiting the foregoing, any and all data furnished by Seller that are required for the reporting of the Product under the Medicaid drug rebate program pursuant to this subsection shall be certified to Buyer by Seller in the same format provided by Seller to CMS.

(e)           Without limiting the foregoing, Buyer agrees that, from and after the Closing Date until the first anniversary of the expiration date of the last lot sold bearing an NDC of Seller, Buyer shall provide to Seller, within twenty-five (25) days after the end of each reporting period, the Governmental Price Reports and other data for such Product reasonably requested by Seller for use by Seller in submitting such Governmental Price Reports in the Drug Data Reporting for Medicaid system for purposes of reporting the AMP and the Best Price (as defined at 42 U.S.C. § 1396r-8(c)(1)(C)).

(f)            Each Party shall promptly notify the other Party upon discovery of any errors in or corrections to the data or other information provided pursuant to Section 5.4(b), (c), (d), or (e) above.

(g)           Buyer shall not make any changes in the wholesale acquisition cost of any Product(s) bearing Seller’s NDC without prior written approval of Seller.

In the event Buyer does not have an existing PHS agreement, Seller shall continue to pay chargebacks for Product bearing an NDC of Seller. Except as set forth in the first sentence of this paragraph, Seller shall invoice Buyer for all actual documented chargeback claims and distributor chargeback fees on distributor invoices relating to all Product bearing an NDC of Seller shipped to a 340B program covered entity dated after the Closing Date, and Buyer shall pay Seller the undisputed amount of such invoice within thirty (30) days of receipt of such invoice. The Parties shall cooperate in good faith to equitably address and apply any PHS refunds obtained after the Closing Date.

(c)           Seller shall notify Buyer within ten (10) days of notice of any inspection, investigation or other inquiry by, or other material governmental notice or communication from CMS, the Department of Health and Human Services Office of the Inspector General, or any other Governmental Body relating to the manufacture, sale, marketing, promotion, distribution, or use of the Product or relating to any Governmental Price Reports submitted by Seller. This obligation extends to any subsequent revisions to such claims even if made after the Closing Date.

5.6 Buyer Governmental Payments and Other Contractual Obligations.

Seller shall be financially responsible for all chargeback claims and associated contracted fees related to Product sold by distributors with Distributor Invoice dates up to and including the Closing Date. With respect to chargeback claims and associated contracted fees related to Product sold by distributors with Distributor Invoice dates after the Closing Date and through the Chargeback Contract Termination Date, Seller shall be financially responsible for such claims and chargeback fees to the extent that such claims and chargeback fees do not relate to more than an aggregate of [***], and Buyer shall be financially responsible with respect to all other such claims and fees.

5.8 Use of Seller Trade Dress.

(a)           As of the Closing Date, Seller hereby grants to Buyer, and Buyer hereby accepts, a non-exclusive, non-transferable, non-sublicensable, royalty-free license to use the Seller Trade Dress, solely to the extent necessary to allow the Buyer to distribute and sell Product labeled with Seller Trade Dress as of the Closing and use any other Purchased Assets containing the Seller Trade Dress in accordance with the terms of this Agreement (the “Seller Trade Dress License”). Buyer acknowledges that the Seller Trade Dress License is being granted solely for transitional purposes and that Buyer shall use all commercially reasonable best efforts to cease its use of the Seller Trade Dress as quickly as is reasonably possible after the Closing Date. Notwithstanding the foregoing, the Seller Trade Dress License will terminate on exhaustion of any Inventory labeled with Seller Trade Dress.

(b)           Buyer shall not (i) add any other labels or marks to, or otherwise alter, the Seller Trade Dress as used by the Seller as of the Closing Date (except as required by Legal Requirement); (ii) change in any way the style of the Seller Trade Dress as used by the Seller as of the Closing Date; or (iii) otherwise use the Seller Trade Dress in any manner other than as specifically provided in this Section 5.8. Buyer acknowledges Seller’s (or its Affiliates’) ownership of the Seller Trade Dress, shall do nothing inconsistent with such ownership, agrees that all use of the Seller Trade Dress by Buyer shall inure to the benefit and be on behalf of the Seller (or its Affiliates), and agrees not to challenge Seller’s (or its Affiliates’) title to the Seller Trade Dress. Nothing in this Agreement shall give Buyer any right, title or interest in the Seller Trade Dress other than the right to use the Seller Trade Dress strictly in accordance with this Section 5.8. All use of the Seller Trade Dress by Buyer under this Section 5.8 shall conform to the standards followed by the Seller (or its Affiliates) prior to the Closing Date, and upon

*              Confidential Information indicated by [***] has been omitted from this filing and filed separately with the Securities Exchange Commission.

28

reasonable notice to Buyer, Seller (or its Affiliates) shall have the right to review the standards used by Buyer after the Closing Date to ensure Buyer’s compliance with this requirement related to the Seller Trade Dress.

(c)           Except as expressly provided under this Section 5.8, Buyer shall not have the right to, and shall not, sublicense, assign, pledge, grant or otherwise encumber or transfer to any Third Party any rights licensed by the Seller (or its Affiliates) to Buyer under this Section 5.8 without the Seller’s prior written consent. The Parties understand and agree that, in addition to all other legal remedies, Seller (and each of its Affiliates) shall be entitled to seek immediate injunctive relief in order to enforce the terms of this Section 5.8, and Buyer agrees (i) not to oppose the imposition of such injunctive relief on any grounds whatsoever, and (ii) to use all commercially reasonable efforts to waive any requirement that Seller post bond or other security in connection with the imposition of such relief. If Buyer shall breach this Section 5.8 (whether or not cured), Seller shall have the right to immediately terminate the Seller Trade Dress License by providing written notice to Buyer.

5.9 Liability for Taxes. Seller shall be responsible for and pay all Taxes arising or resulting from the ownership or use of the Purchased Assets on or prior to the Closing Date.

5.10                Seller Accounts Receivable.

In the case of the receipt by Buyer of any payment from any obligor of both Seller and Buyer then, unless otherwise specified by such obligor, such payment shall be applied first to amounts owed to Seller with the excess, if any, retained by Buyer. In the event that, subsequent to the Closing, Seller or any of its Affiliates receives any payments from any obligor with respect to an account receivable of Buyer for any period after the Closing Date, then Seller shall, within thirty (30) days following the end of the calendar month in which such receipt occurs and subject to the provisions of the Transition Services Agreement, including Section 3 and Annex A thereof, remit the full amount of such payment to Buyer. In the case of the receipt by Seller of any payment from any obligor of both Seller and Buyer then, unless otherwise specified by such obligor, such payment shall be applied first to amounts owed to Seller with the excess, if any, remitted to Buyer.

5.11                Non-Competition Covenants.

(a)           From the Closing until the earlier to occur of (a) the [***] anniversary of the Closing Date, (b) payment by Buyer of both Deferred Payments, or (c) permanent revocation of the Drug Authorization by the FDA, neither Buyer nor any Affiliate of Buyer shall, directly or indirectly, engage in the commercialization of any AB-rated generic pharmaceutical product to Tussionex® (a “Competing Product”); provided, that the foregoing will not prevent Buyer or any Affiliate of Buyer from participating or engaging in any activity, or holding any interest in, or otherwise dealing with, any Person, where such participation, engagement, holding or dealing does not primarily relate to a Competing Product. For clarity, in the event Buyer has paid both Deferred Payments at any time, the restrictions in the foregoing sentence shall have no further effect and Buyer shall be permitted to engage in the commercialization of any Competing

29

Product.

(b)           Without the express prior written consent of Buyer, Seller shall not, at any time during the period commencing on the Closing Date and ending on the [***] anniversary of the Closing Date, (i) directly or indirectly, engage in the commercialization of a Competing Product; provided, that the foregoing will not prevent Seller from participating or engaging in any activity, or holding any interest in, or otherwise dealing with, any Person, where such participation, engagement, holding or dealing does not primarily relate to a Competing Product; or (ii) attempt to induce any employee of Buyer (or of any Affiliate of Buyer) to terminate his or her employment with Buyer (or with any Affiliate of Buyer), or attempt to interfere with the relationship or prospective relationship (in either case, related primarily to the Product) between Buyer (or any Affiliate of Buyer) and any creditor, licensee, customer, prospective customer, employee or other party.

(c)           Each Party hereby acknowledges and agrees that in the event of any breach of this Section 5.11 by such Party, the other Party may suffer an irreparable injury such that no remedy at law would adequately protect or appropriately compensate such injured Party. Accordingly, each Party agrees that the other Party may seek to enforce this Section 5.11 by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that such Party may have for a breach of this Section 5.11.

(d)           Recognizing the specialized nature of commercializing the Product, Seller and Buyer each acknowledges and agrees that the duration, geographic scope and activity restrictions of the covenants set forth in this Section 5.11 are reasonable. In the event that the covenants set forth in this Section 5.11 shall ever be deemed to exceed the time, geographic scope or other limitations permitted by applicable Legal Requirement in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service or other limitations permitted by applicable Legal Requirement.

5.12                Reporting and Recordkeeping Requirements; Audit Rights.

(a)           Not later than forty-five (45) days after the end of each calendar month until both Deferred Payments have been made by Buyer, Buyer shall deliver to Seller a monthly report setting forth the Net Sales for such month.

(b)           Buyer shall, and shall cause its Affiliates to, maintain complete and accurate books and records in connection with the sale of the Product, as necessary to allow the accurate calculation of Net Sales of the Product and compliance with Buyer’s obligations hereunder, and Buyer shall maintain such books and records, or cause such books and records to be maintained, for a period of at least three (3) years after the end of the Calendar Year in which they were generated, or for such longer period as may be required by applicable Legal Requirements. From and after the Closing, Buyer shall include provisions in all of its agreements entered into after Closing and shall use commercially reasonable efforts with respect to its existing agreements to cause Selling Persons to maintain books and records consistent with those required under this Section 5.12(b) by Buyer and its Affiliates. For purposes of this Agreement, “Selling Person” means Buyer, each of its Affiliates and each (i) licensee, sublicensee, assignee or other grantee of

rights from Buyer or any of its Affiliates or another Selling Person to Exploit the Product or (ii) Affiliate of the foregoing.

(c)           Upon not less than thirty (30) days’ written notice to Buyer, Seller shall have the right, but not more than once per Calendar Year, to engage an independent certified public accounting firm reasonably acceptable to Buyer to examine the books and records specified in Section 5.12(b) as may be reasonably necessary to determine or verify the amount of Net Sales per calendar month or to obtain information as to Deferred Payments payable in the case of failure to report or pay pursuant to the terms of this Agreement; provided, however, that any such examination shall not cover records of any calendar month previously subject to an audit under this Section 5.12(c). Such accounting firm shall conduct such examination, and Buyer shall make such books and records available, during normal business hours at the facility(ies) where such books and records are maintained. The independent accounting firm will prepare and provide to each Party a written report for the calendar months in question, which each Party shall accept as determinative stating whether the reports submitted pursuant to Section 5.12(a) are correct or incorrect, any required corrections thereto, and the amounts of any Deferred Payments payable under this Agreement. Seller shall be responsible for the expenses of the independent certified public accounting firm, except that Buyer shall promptly reimburse Seller for such expenses if such firm determines that Buyer underreported Net Sales of the Product and such underreporting of Net Sales resulted in or contributed to Buyer’s failure to make a Deferred Payment when due under this Agreement.

Notwithstanding anything to the contrary herein, the Parties agree that Buyer’s obligation under subsection (b) and (c) above shall expire and terminate when both Deferred Payments have been made by Buyer.

5.13                Commercialization; Compliance with Legal Requirements. From the Closing until the payment by Buyer of both Deferred Payments, Buyer (a) shall use, and cause its Affiliates to use, Commercially Reasonable Efforts to market, distribute and sell the Product in the United States and (b) shall comply, cause its Affiliates to comply, and use Commercially Reasonable Efforts to cause Third Parties responsible for such activities to comply with all Legal Requirements applicable to the Exploitation of the Product in the United States. Upon the occurrence of any material breach by Buyer or any of its Affiliates of Section 5.11 or this Section 5.13 and the failure by Buyer to cure such breach within thirty (30) days following Buyer’s receipt of written notice of such breach from Seller (the “Cure Period”), and notwithstanding any other remedies Seller may have under this Agreement or otherwise, then both Deferred Payments (without regard to whether otherwise payable pursuant to Section 2.2(c), but only if previously unpaid) shall, upon expiration of the Cure Period, become immediately due and payable.

5.14                Effectiveness of the Termination Agreement. Buyer and Seller shall cause the Termination Agreement to become effective immediately following the execution of this Agreement.

6.6 Procedure for Indemnification.

(a)           All claims for indemnification by a Buyer Indemnified Party or a Seller Indemnified Party (collectively, the “Indemnified Persons”) pursuant to this ARTICLE 6 shall be made in accordance with the provisions of this Agreement.

(b)           If a Third Party asserts that an Indemnified Person is liable to such Third Party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Person may be entitled to indemnification pursuant to this ARTICLE 6 (a “Third Party Claim”), then such Indemnified Person may make a claim for indemnification pursuant to this ARTICLE 6 and shall be reimbursed in accordance with the applicable provisions of this Agreement for any such Damages for which it is entitled to indemnification pursuant to this ARTICLE 6 (subject to the right of the indemnifying Party to dispute the Indemnified Person’s entitlement to indemnification under the applicable terms of this Agreement).

(c)           The Indemnified Person shall give prompt written notification to Seller or Buyer, as the case may be, of the commencement of any Proceeding relating to a Third Party Claim for which indemnification pursuant to this ARTICLE 6 may be sought; provided, however, that no delay on the part of the Indemnified Person in notifying Seller or Buyer, as the case may be, shall relieve Seller or Buyer, as the case may be, of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure. Within thirty (30) days after delivery of such notification, Seller or Buyer, as the case may be, may, upon written notice thereof to the Indemnified Person, assume control of the defense of such Proceeding provided Seller or Buyer, as the case may be, acknowledge(s) in writing to the Indemnified Person that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Person in connection with such Proceeding constitute Damages for which the Indemnified Person shall be entitled to indemnification pursuant to this ARTICLE 6. If neither Seller nor Buyer, as the case may be, so assumes control of such defense, the Indemnified Person shall control such defense. The Party not controlling such defense may participate therein at its own expense. The Party controlling such defense shall keep the other Party advised of the status of such Proceeding and the defense thereof. The Indemnified Person shall not agree to any settlement of such Proceeding without the prior written consent of Seller or Buyer, as the case may be, which shall not be unreasonably withheld. Neither Seller nor Buyer, as the case may be, shall agree to any settlement of such Proceeding without the prior written consent of the Indemnified Person, which shall not be unreasonably withheld.

(d)           A claim for indemnification for any matter not involving a Third Party Claim may be asserted by prompt written notice specifying the factual basis of that claim in reasonable detail to the Party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying Party shall not preclude the indemnified Party from any indemnification which it may claim in accordance with this ARTICLE 6 except to the extent that the indemnifying Party can demonstrate actual prejudice to its defenses or counterclaims or otherwise, or increased or aggravated Damages as a result of such failure.

(a)           In the event that Seller is required to provide indemnification hereunder to any Buyer Indemnified Parties, such indemnification obligation shall be paid to Buyer (for further distribution between Buyer and other Buyer Indemnified Parties, as appropriate). Any payment made to Buyer pursuant to this ARTICLE 6 shall be treated for Tax purposes as a reduction in the Purchase Price unless otherwise required by applicable Legal Requirement.

(b)           In the event that Buyer is required to provide indemnification hereunder to Seller Indemnified Parties, such indemnification obligation shall be paid to Seller (for further distribution between Seller and other Seller Indemnified Parties, as appropriate).

6.8 Certain Other Limitations.

(a)           Damages Net of Insurance. Notwithstanding anything to the contrary in this Agreement, the amount of any Damages for which indemnification is provided under this ARTICLE 6 shall be net of any actual cash insurance recoveries. A Party shall use commercially reasonable efforts to seek an insurance recovery. If a Party obtains a recovery, the Party’s indemnity claim shall not be offset to the extent of the Party’s expenses in obtaining such recovery. An insurer who is otherwise obligated to pay a claim is not relieved of the responsibility with respect to the claim and has no subrogation rights with respect to the claim, in either instance, solely by virtue of the indemnification provisions of this ARTICLE 6. A Party that provides indemnification hereunder is subrogated to the rights of an Indemnified Person upon payment of the relevant indemnity claim.

(b)           Knowledge. To the Knowledge of Buyer and to the Knowledge of Seller as of the Closing Date, there are no facts or circumstances that would serve as the basis for a claim by Buyer or Seller, respectively, against the other Party based upon a breach of any of the representations, warranties, covenants and agreements of Seller contained in this Agreement.

(c)           No Consequential Damages, etc. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IN NO EVENT SHALL ANY PARTY HERETO OR ITS AFFILIATES BE LIABLE OR RESPONSIBLE TO ANY OTHER PARTY HERETO FOR INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION ANY CLAIMS FOR DAMAGES BASED UPON LOST REVENUES OR PROFITS, HOWEVER CAUSED OR ON ANY THEORY OF LIABILITY THAT ARISE OUT OF OR RELATE TO THIS AGREEMENT OR THE PERFORMANCE OR BREACH THEREOF, EXCEPT WITH RESPECT TO ANY INDEMNIFICATION CLAIM UNDER SECTION 6.2 OR SECTION 6.3 FOR DAMAGES ACTUALLY PAID TO A THIRD PARTY PURSUANT TO A THIRD PARTY CLAIM. FOR CLARITY, THIS SECTION 6.8(C) SHALL NOT BE CONSTRUED OR DEEMED TO LIMIT, IN ANY WAY, SELLER’S RECOVERY OF THE DEFERRED PAYMENTS AS PROVIDED UNDER THIS AGREEMENT.

35

6.9 Indemnification Exclusive Remedy. Buyer and Seller acknowledge and agree that, subject to any rights or remedies expressly set forth herein including in Section 2.2, Section 5.12 and Section 5.13, their sole and exclusive remedy with respect to any and all Damages relating to the subject matter of this Agreement, or otherwise regarding the transactions contemplated by this Agreement, shall be pursuant to the indemnification provisions set forth in this ARTICLE 6. In furtherance of the foregoing, and subject to any rights or remedies expressly set forth herein, Buyer hereby waives, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action it may have against Seller in law or equity, except such rights, claims and causes of action based upon Buyer’s right to indemnification under this Agreement, and Seller hereby waives, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action it may have against Buyer in law or equity except such rights, claims and causes of action based upon Seller’s rights to indemnification under this Agreement; provided, however, that in addition to such indemnification and any rights or remedies expressly set forth herein, the Parties may seek equitable remedies, including specific performance in accordance with applicable Legal Requirements or seek any remedy on account of any fraud committed with the intent to deceive by any Party hereto.

The Parties agree (a) to furnish upon request to each other such further information, (b) to execute and deliver to each other such other documents, and (c) to do such other acts and things, all as any other Party may reasonably request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

7.6 Waiver. The rights and remedies under this Agreement are cumulative and are in addition to and not in substitution for any other rights and remedies available at law or in equity or otherwise, except to the extent expressly provided in ARTICLE 6. Neither the failure nor any delay by any Party in exercising any right, power, or privilege under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege. To the maximum extent permitted by applicable law, (a) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by a Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party; (b) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on a Party will be deemed to be a waiver of any obligation of such Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

7.7 Entire Agreement and Modification. Except for the Confidentiality Agreement, which remains in full force and effect, this Agreement supersedes all prior agreements between the Parties with respect to its subject matter and constitutes (along with the documents referred to in this Agreement) a complete and exclusive statement of the terms of the agreement between the Parties with respect to its subject matter. This Agreement may not be amended or modified except by a written agreement duly executed by each of the Parties hereto.

7.8 Disclosure Letter. The information and disclosures in the Disclosure Letter are intended only to qualify and limit the representations and warranties of Seller contained in this Agreement and shall not be deemed to expand in any way the scope or effect of any of such representations and warranties. The section numbers in the Disclosure Letter correspond to the Section numbers in this Agreement; provided, however, that any information disclosed therein under any Section number shall be deemed to be disclosed and incorporated in any other section of this Agreement where the applicability of such disclosure would be reasonably apparent under the circumstances. Capitalized terms used but not defined in the Disclosure Letter shall have the same meanings given them in this Agreement. In the event of any inconsistency between the statements in the body of this Agreement and those in the Disclosure Letter (other than an exception expressly set forth as such in the Disclosure Letter with respect to a specifically identified representation or warranty), the statements in the body of this Agreement will control.

7.9 Assignments, Successors and No Third-Party Rights. This Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and assigns of the Parties, and Buyer (and any assignee of Buyer) agrees to cause any assignee of Buyer or of such assignee to acknowledge to Seller in writing its obligation to make Deferred Payments hereunder. Subject to the provisions of this Section 7.9, each Party may assign, transfer or convey this Agreement, in whole or in part, or any of its rights or obligations under this

38

Agreement to its Affiliate or to a Third Party without the consent of the other Party. Prior to payment by Buyer of both Deferred Payments, in connection with any sale, transfer or other disposition of all or substantially all of Buyer’s assets or business, whether direct or indirect, by purchase, merger, consolidation or otherwise or the sale or assignment of all of Buyer’s (or its assignee’s or Affiliate’s) rights in the Product, such Buyer (or its assignee) shall assign this Agreement and its rights, together with its obligations hereunder (including the obligation to make Deferred Payments); for the avoidance of doubt, the foregoing shall not apply to (a) any grant of any license, distribution, marketing or other similar development or commercial right in and to the Product or (ii) any debt or other transaction in which Buyer grants a security interest in the Product and/or assigns its right to receive proceeds from sales of the Product or grant a security interest in such right to receive proceeds of sales in the Product to one or more Third Parties providing financing to Buyer pursuant to the terms of a security or other agreement related to such financing (e.g., for purposes of a royalty financing arrangement), it being acknowledged and agreed that, notwithstanding any such arrangement, Buyer shall remain obligated to make any required Deferred Payments hereunder. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the Parties to this Agreement any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement. This Agreement and all of its provisions and conditions are for the sole and exclusive benefit of the Parties to this Agreement and their successors and permitted assigns.

7.10                                                Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

In the event of any conflict between the provisions of this Agreement and the provisions of any Other Transaction Document, the provisions of this Agreement shall prevail.

7.12                                                Time of the Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.

Re:                             Termination of Development and Manufacturing Agreement

Dear Mr. Bruenig and Mr. McBean:

Termination

Through this letter (“Letter Agreement”), the Parties (as defined below) mutually agree to terminate, subject to the terms and conditions hereof and as applicable, those agreements set forth on Exhibit A, attached hereto. The Development Agreement and the Quality Agreement, as defined in Exhibit A, are collectively referred to as “Agreement”. Neos Therapeutics, L.P. (“Neos LP”), Neos Therapeutics, Inc. (“Neos Inc.”), CPI Technology, Inc., Coating Place, Inc. (“Coating Place” or “CPI”), Cornerstone BioPharma, Inc. (“Cornerstone”), and Chiesi USA, Inc. (“Chiesi”) are referred to in this Letter Agreement individually as a “Party” or in combination as the “Parties.” Except as otherwise specifically stated in this Letter Agreement, each of the agreements set forth on Exhibit A and all of their respective provisions shall be terminated as of the Effective Date.

Survival

As between Neos LP (and its affiliates) and Cornerstone (and its affiliates), the following provisions of the Development Agreement shall survive termination of the Development Agreement and remain in full force and effect with respect to the rights and obligations of each of Cornerstone and Neos LP: Sections 9.1-9.6, 9.9-9.13 (Intellectual Property); 10 (Confidential Information); 12 (Dispute Resolution); 13 (Indemnification) (but only with respect to Direct Costs arising out of or in connection with actions, suits, proceedings or claims by persons other

than the Releasing Parties or Released Parties (collectively, “Third-Party Claims”)); 14 (Notices); 19 (Governing Law); and any definitions required to interpret the foregoing (collectively the “Surviving Provisions”); provided, however, for purposes of clarification, in no event shall any provisions of the Development Agreement remain in effect with respect to Coating Place (and its affiliates) whatsoever.

Release

Each Party, on behalf of itself and its respective assigns, successors, predecessors, directors, trustees, governors, officers, affiliates, subsidiaries, members, partners, shareholders, attorneys, employees and agents (each a “Releasing Party”), hereby releases and forever discharges the other Parties and the other Parties’ respective assigns, successors, predecessors, directors, trustees, governors, officers, affiliates, subsidiaries, members, partners, shareholders, attorneys, employees and agents (the “Released Parties”) from any and all actions, causes of action, claims or demands for damages, suits, debts, sums of money, accounts, costs, expenses, compensation, consequential damages, covenants, interest, liens, attorneys’ fees, or any other thing whatsoever, in law, equity or otherwise, whether now known or unknown or which have ever existed, now exist or which may exist in the future (except to enforce the terms of this Letter Agreement) which each Releasing Party, its assigns, successors, predecessors, directors, trustees, governors, officers, affiliates, subsidiaries, members, partners, shareholders, attorneys, employees and agents may have against the other Released Parties based upon or arising out of the Agreement and all other agreements being terminated hereunder, including, for the avoidance of doubt, any amounts of “Net Profits” payable under the Development Agreement (except with respect to: (a) Net Profits payable to Neos LP or its affiliates as otherwise agreed between Neos Inc. (and its affiliates) and Cornerstone (and its affiliates) under the Asset Purchase Agreement (defined below) and (b) certain amounts payable for work in process drug resin complex delivered to, and accepted by, Neos and owing to Coating Place by Neos under the Side Letter (as defined below)), which amounts have been agreed to by the relevant parties and satisfied prior to effectiveness of this Letter Agreement. Notwithstanding the foregoing, (a) Neos LP (and its affiliates) and Cornerstone (and its affiliates), do not release each other from any liability with respect to (i) Third-Party Claims or (ii) claims for breaches of the Surviving Provisions that occur on or after the Effective Date, and (b) the Parties do not release each other with respect to their obligations under this Letter Agreement, including, for the avoidance of doubt, Cornerstone’s obligations set forth under the headings “CPI Confidential Information” and “CPI IP”, below.

Conflicts

In connection with the termination of the Agreement, Neos LP and Coating Place have agreed to the payment terms set forth in the letter agreement between Neos LP and Coating Place, dated as of the date hereof (the “Side Letter”). It is a condition precedent to the effectiveness of this Letter Agreement that the Side Letter, the Supply Agreement (as defined below), that certain Asset Purchase Agreement between Cornerstone and Neos Inc., dated as of the date hereof (the “Asset Purchase Agreement”), and that certain Transition Services Agreement between Cornerstone and Neos Inc. dated as of the date hereof (the “Transition Services Agreement”) are executed and delivered by the applicable Parties immediately prior to the execution hereof. The

Parties agree that nothing in this Letter Agreement (including the releases granted in the preceding paragraph) shall affect the terms or enforceability of the Side Letter, the Asset Purchase Agreement, the Transition Services Agreement or that certain Supply Agreement between Neos Inc. and Coating Place, dated as of the date hereof (the “Supply Agreement”), and, in the event of a conflict between this Letter Agreement and any provision of any such agreement, the terms and conditions of such agreement shall prevail over this Letter Agreement.

CPI Confidential Information

The Parties acknowledge that certain of Coating Place’s confidential and proprietary information regarding the manufacture of drug resin complex for the Product (as defined in the Supply Agreement) are contained within the Chemistry, Manufacturing and Controls portion of the ANDA for the Product (“CPI Information”). The Parties acknowledge and agree that CPI has previously disclosed to Cornerstone or its affiliates (excluding, for the avoidance of doubt, Neos LP, Neos Inc., or any of their respective affiliates), or Cornerstone or its affiliates (excluding, for the avoidance of doubt, Neos LP, Neos Inc., or any of their respective affiliates) otherwise had access to, such CPI Information under the Development Agreement. Cornerstone, on behalf of itself and its affiliates, hereby agrees that it shall keep confidential, and shall not use in any manner whatsoever, the CPI Information. Cornerstone, on behalf of itself and its affiliates, hereby agrees that it shall keep confidential, and shall not use in any manner whatsoever, any other information previously disclosed in writing, orally, visually or in any other manner by CPI (or its affiliates) or otherwise made available to Cornerstone which CPI considers to be and treats as proprietary or confidential (collectively, the “CPI Confidential Information”); provided, however, that the CPI Confidential Information shall not include information that (i) at the time of disclosure was, or thereafter has become, generally available to the public other than as a result of, directly or indirectly, any violation of this Letter Agreement by Cornerstone (or its affiliates); (ii) at the time of disclosure was, or thereafter has become, available to Cornerstone (or any of its affiliates) on a non-confidential basis from a third party that is not and was not, at the time of disclosure, itself under any obligation of confidentiality or nondisclosure to Coating Place (or any of its affiliates) or any other person with respect to such information; (iii) by written evidence can be shown by Cornerstone (or any of its affiliates) to have been independently developed by or for Cornerstone (or any of its affiliates); or (iv) Cornerstone (or any of its affiliates) establishes by competent proof was in its possession at the time of disclosure by Coating Place (or any of its affiliates).

In the event that CPI Information or CPI Confidential Information is required to be disclosed by Cornerstone or (any of its affiliates) pursuant to applicable federal, state and local laws, rules, regulations, orders and requirements, Cornerstone (or its affiliates) may permissibly make such disclosure; provided, that, Cornerstone will provide CPI with prompt notice so that CPI may seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Section; provided, further, that, in the event that such protective order or other remedy is not obtained, or that CPI waives compliance in writing with the provisions of this Section, Cornerstone or its representatives will furnish only that portion of the CPI Confidential Information that is legally required to be disclosed (by judicial or similar process that would subject Cornerstone or its representatives to contempt or similar penalty for failure to disclose)

and will exercise best efforts to obtain reliable assurance that confidential treatment will be afforded to the CPI Confidential Information.

Notwithstanding anything to the contrary in the foregoing, the Parties acknowledge and agree that the disclosure by Cornerstone (or any of its affiliates) of the CPI Confidential Information in the manner contemplated by Section 2.6(b) of the Asset Purchase Agreement is expressly permitted by and shall not constitute a violation of this Letter Agreement.

CPI IP

Cornerstone, on behalf of itself and its affiliates, acknowledges and agrees that it does not have, and never has had, any ownership rights in or to the CPI IP, and upon the Effective Date, shall not have any rights to use as a licensee or otherwise, the CPI IP. For purposes hereof, “CPI IP” means the CPI Registered IP and all applicable know-how and trade secrets of Coating Place (or its affiliates) related to the Product and the CPI Registered IP; “CPI Registered IP” means the CPI Patents and the CPI Patent Application, collectively; “CPI Patents” means U.S. Patent Number 8,343,546 and U.S. Patent Number 7,871,645; and “CPI Patent Application” means U.S. Patent Application Number 11/674,940.

Miscellaneous

Your signatures below and my signatures on behalf of Neos LP and Neos Inc. below represent confirmation by each of us that the terms set forth in this Letter Agreement form the full, complete and enforceable mutual agreement and release among Coating Place, CPI Technology, Inc., Cornerstone, Chiesi, Neos LP and Neos Inc., regarding the termination described in this Letter Agreement (but without prejudice to the respective rights and obligations of Cornerstone, Chiesi, Neos LP, Neos Inc., Coating Place and their respective affiliates under the Side Letter, the Asset Purchase Agreement, the Transition Services Agreement and the Supply Agreement) and that each of us is an authorized officer and signatory of our respective companies for purposes of entering into this Letter Agreement.

This Letter Agreement shall take effect immediately following the execution of the Asset Purchase Agreement, the Side Letter, and the Supply Agreement all of which shall, for purposes of this Letter Agreement, be deemed to be effective simultaneously (the “Effective Date”). This Letter Agreement will be binding on and inure to the benefit of the successors and assigns of the Parties to this Letter Agreement. This Letter Agreement may be executed in any number of counterparts, each of which will be deemed to be an original, all of which together will be deemed one and the same instrument. Facsimile, .pdf or other electronically transmitted signatures will be treated as original signatures.
