ARTICLE 4

GRANT OF INTEREST IN KP415

4.1 Division of Value Generally. Subject to the terms and conditions set forth in this Agreement, the Parties acknowledge and agree that MSRx shall have the right to receive an amount equal to [***] of any and all Value. Upon the occurrence of a Program Sale Transaction or KemPharm Sale Transaction, the Value to be paid to MSRx (or the amount to be deposited in escrow in accordance with Section 4.2, as the case may be) shall be paid to MSRx (or the escrow agent, as the case may be) directly out of the closing proceeds and any other consideration (and post-closing proceeds and/or other consideration, if any) of such Program Sale Transaction or KemPharm Sale Transaction simultaneously with and when each payment by such Third Party is made to KemPharm or any of its Affiliates, and/or any of their respective equity holders, of any and all such proceeds or the delivery of other consideration therefore whenever made. KemPharm shall arrange in the agreement for a Program Sale Transaction or KemPharm Sale Transaction that payment of such Value to MSRx (or the amount to be deposited in escrow pursuant to Section 4.2, as the case may be) shall be made by wire transfer of immediately available funds to an account designated by MSRx (or to the escrow agent, as the case may be), and the delivery of such other consideration representing any such Value (or the amount to be deposited in escrow pursuant to Section 4.2, as the case may be) shall be made to the address of MSRx set forth in this Agreement or as otherwise designated by MSRx (or to the escrow agent, as the case may be). In the event that MSRx is properly paid in full all of its share under this Agreement of the Value of a Program Sale Transaction or KemPharm Sale Price directly by the Third Party purchaser in such Program Sale Transaction or KemPharm Sale Transaction out of the proceeds thereof in accordance with this Article 4, MSRx shall have no right to make a Claim against KemPharm for KemPharm’s share of the Value received from such Third Party purchaser out of the proceeds of such Program Sale Transaction or KemPharm Sale Transaction, as the case may be.

4.2 KemPharm Sale Transaction. If KemPharm or an Affiliate holding rights, title or interests in or to KP415 enters into a KemPharm Sale Transaction, then such transaction shall include MSRx’s rights and interests in and to KP415; provided that MSRx shall be paid its share of the Value of the KemPharm Sale Price. The KemPharm Sale Price shall constitute Value to the extent that the KemPharm Sale Price is attributable, in whole or in part, to any of KemPharm’s or an Affiliate’s rights, title or interests in or to KP415. Upon proper payment of such Value to MSRx in connection with a KemPharm Sale Transaction, MSRx’s rights and interests in and to KP415 shall be terminated unless after the consummation of such KemPharm Sale Transaction KemPharm or any of its Affiliates, and/or any of their respective equity holders, retains directly or indirectly any rights, title or interests in and to KP415, in which event such rights and interests of MSRx shall continue and survive the consummation of such KemPharm Sale Transaction and MSRx shall be paid its share of the Value of the KemPharm Sale Price with respect to such KemPharm Sale Transaction. The interests of MSRx which shall survive pursuant to the foregoing sentence shall be limited to the extent of the remaining interest in KemPharm and its Affiliates held by their respective equity holders, including future Value payments made to such equity holders and Value received by such equity holders in any subsequent transactions including, without limitation, any Program Sale Transactions and any KemPharm Sale Transactions. KemPharm or the Affiliate who is a party to the KemPharm Sale Transaction shall provide to MSRx written notice of its intent to enter into a KemPharm Sale Transaction, which notice shall specify the consideration and purchase price to be paid to KemPharm, its Affiliates and/or their respective equity holders in such KemPharm Sale Transaction. Such notice shall be delivered to MSRx as soon as reasonably practicable, but in no event later than five (5) Business Days after the execution of any agreement contemplating such KemPharm Sale Transaction and no later than ninety (90) days prior to the consummation of such KemPharm Sale Transaction. If the Parties cannot agree on the determination of the Value contained within a KemPharm Sale Price within ten (10) days of such notice by KemPharm to MSRx, then such Value shall be determined by an independent valuation expert selected by mutual written agreement of the Parties. In the event that the Parties are unable to mutually agree upon the selection of an independent valuation expert within five (5) Business Days of the expiration of such ten-day period, then such Value shall be determined in accordance with the following procedures: Each of the Parties shall select its own independent valuation expert and pay all costs associated with its own valuation expert. The two independent valuation experts shall prepare a written determination of such Value within three (3) months of selection. If the determination of the two valuation experts vary by [***] or less, the Parties shall accept as final and binding the average of the determination by the two independent valuation experts as the Value attributed in such KemPharm Sale Transaction. If the results of the foregoing two determinations vary by more than [***], then the two valuation experts shall select a third independent valuation expert to prepare its own valuation of the Value attributed to such KemPharm Sale Transaction. The third valuation expert will, at a minimum, evaluate the valuations of the first two valuation experts and conduct its own analyses as necessary to support its own valuation. The three independent valuation experts shall agree to comply with this schedule of performance before accepting appointment. The Parties shall accept as final and binding the average of the determinations by the three independent valuation experts as the Value attributed in such KemPharm Sale Transaction. The Parties agree that each independent valuation expert engaged for the purposes of determining Value pursuant to this Section 4.2 shall be at least a partner or director of a nationally recognized appraisal firm, which may be an investment banking firm, a certified public accounting firm, or any other firm that performs appraisal and valuation services in the pharmaceutical industry. The Parties agree that any and all costs associated with the first (and, if applicable, the third) valuation expert and its valuation determination shall be paid equally by MSRx and KemPharm. The Parties also agree that the Value shall be equal to a percentage of the KemPharm Sale Price, which percentage shall be proportionate to the value of KemPharm’s and/or its Affiliate’s rights, title or interests in KP415 expressed as a percentage of the aggregate value of the overall portfolio of tangible and intangible assets as a going concern that are included within the KemPharm Sale Transaction. For the sake of clarity, each individual asset of KemPharm or its Affiliates included within the KemPharm Sale Transaction, including KP415, shall be assigned a percentage that represents each individual asset’s relative contribution to the KemPharm Sale Price, such that the Value in question to be shared by the Parties shall be clearly defined and distinct from all other assets solely owned by KemPharm and/or its Affiliates. The Parties also agree that any valuation shall be conducted in accordance with the terms set forth generally in Exhibit B. The Parties agree that, in the event that such valuation determination is not made prior to the scheduled closing of the KemPharm Sale Transaction despite the Parties acting in good faith and with reasonable diligence to obtain such valuation determination in accordance with this Section 4.2, KemPharm shall have the right to close the KemPharm Sale Transaction on or after the schedule closing date; provided, however, that [***] of the KemPharm Sale Price shall be deposited into an escrow account out of the proceeds or other consideration paid under the KemPharm Sale Transaction and released upon completion of the determination of Value in accordance with this Section 4.2. The agent of the aforementioned escrow account shall be mutually agreed upon in writing by the Parties, who shall be instructed to distribute the escrowed proceeds and consideration upon completion of the Value determination in such proportions as shall correctly pay MSRx its share of the Value of the KemPharm Sale Price, and the remaining balance shall be paid to KemPharm (or to its Affiliates as instructed by KemPharm). In the event that the share of the Value upon completion of the Value determination exceeds the amount held in such escrow, KemPharm or its Affiliates shall pay to MSRx within five (5) days of such determination the difference between the share of the Value determined in accordance with this Section 4.2 and the amount in escrow.

4.3 Limitation on MSRx’s Rights to KP415. Except as otherwise expressly provided in this Article 4, MSRx shall have no rights or interest in or to KP415. Further, KemPharm shall have no obligations to MSRx to take any actions to develop or Commercialize KP415. Moreover, MSRx acknowledges the option to purchase KP415 which is granted to Shire under the Shire LOI, which, if such option is exercised by Shire under the Shire LOI, shall be deemed to be a Program Sale Transaction and MSRx shall be entitled to its share of Value with respect thereto under Section 4.1.

ARTICLE 5

CONFIDENTIAL INFORMATION

5.1 Confidential Information. Each of the Parties (“Receiving Party”) shall keep all Confidential Information received from the other Party (“Disclosing Party”) with the same degree of care it maintains the confidentiality of its own Confidential Information, which in no event shall be less than a reasonable degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than in performance of this Agreement or disclose the same to any other Third Party other than to such of its employees, directors, officers, representatives, consultants, and agents (collectively, an “Agent”) who have a need to know such Confidential Information to implement the terms of this Agreement or enforce its rights under this Agreement, or to a Third Party Licensee. A Receiving Party shall advise any Agent or Third Party Licensee who receives such Confidential Information of the confidential nature thereof and of the obligations contained in this Agreement relating thereto. Upon termination of this Agreement, the Receiving Party shall use Commercially Reasonable Efforts to return or destroy all documents, tapes or other media containing Confidential Information of the Disclosing Party that remain in the Receiving Party’s or its Agents’ possession, except that the Receiving Party may keep one (1) archival copy of the Confidential Information in the legal department files of the Receiving Party or its outside counsel. Such archival copy shall be deemed to be the property of the Disclosing Party, and shall continue to be subject to the provisions of this Section 5.1. The above restrictions set forth in this Section 5.1 on the use and disclosure of Confidential Information shall not apply to any information which (a) is already known to the Receiving Party at the time of disclosure by the Disclosing Party, as demonstrated by competent proof (other than as a result of prior disclosure under any agreement between the Parties with respect to confidentiality), (b) is or becomes generally available to the public other than through any act or omission of the Receiving Party in breach of this Agreement, (c) is acquired by the Receiving Party from a Third Party who is not directly or indirectly under an obligation of confidentiality to the Disclosing Party with respect to same, or (d) is developed independently by the Receiving Party without use, direct or indirect, of Confidential Information. In addition, nothing in this Article 5 shall be interpreted to limit the ability of either Party to disclose its own Confidential Information to any other Person on such terms and subject to such conditions as it deems advisable or appropriate.

A specific item of Confidential Information shall not be covered or deemed to be covered by the foregoing exclusions merely because a general category of information containing such specific item is within the scope of such exclusions. Notwithstanding anything in this Agreement to the contrary, in the event the Receiving Party becomes, or anticipates that it may become, legally compelled to disclose any of the Confidential Information, the Receiving Party will provide the Disclosing Party with prompt notice so that the Disclosing Party may seek a protective order or other appropriate remedy or waive compliance with the provisions of this Agreement. If a full protective order or other appropriate remedy is not obtained, the Receiving Party will disclose only that portion of the Confidential Information which it remains legally compelled to disclose, and will exercise its reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Confidential Information.

If any portion of the Confidential Information falls into one of the above exceptions, the remainder of the information shall continue to be subject to the requirements of the Agreement. Further, Confidential Information shall not be deemed within the foregoing exceptions if such Confidential Information: (i) is specific and merely embraced by more general information in the public domain or in the receiving party’s possession; or (ii) is a combination which might be pieced together so as to reconstruct such Confidential Information from multiple sources, none of which show the whole combination, the principles of operation and/or method of use.

5.2 Permitted Disclosure and Use. Notwithstanding Section 5.1, a Party may use and disclose Confidential Information belonging to the other Party only to the extent such use and/or disclosure is reasonably necessary to perform its obligations under this Agreement or comply with applicable laws or the regulations of any government authority or any security exchange on which its shares or those of any group company are, or in the process of being, listed. If a Party deems it necessary to disclose Confidential Information of the other Party pursuant to this Section 5.2, such Party shall where lawful to do so give such reasonable advance notice of such disclosure, to the other Party as it is able to do to permit such other Party to object to such disclosure or to take measures to ensure confidential treatment of Confidential Information that is being disclosed.

5.3 Public Announcements; Press Release. Except as may be expressly permitted under this Section 5.3, or required by applicable laws or the regulations of any security exchange on which its shares or those of any group company are listed or in the process of being listed, neither Party will make any public announcement of any information regarding the existence, terms or conditions of this Agreement without the prior written approval of the Parties. Once any writtei1 statement is approved for disclosure by the other Party or information is otherwise made public in accordance with this Section 5.3, either Party may make a subsequent public disclosure of the contents of such statement without further approval of the other Party. Nothing in the foregoing, however, shall prohibit a Party from making such disclosures as may be necessary or reasonably appropriate in order to comply with applicable law or any rule or regulation of any nationally recognized securities exchange; in such event, however, the Party making the disclosure shall use good faith efforts to consult with the other Party prior to such disclosure and consider in good faith such other Party’s proposed modifications and, where applicable, shall request confidential treatment to the extent available.

5.4 Confidentiality of this Agreement. The terms of this Agreement shall be Confidential Information of each Party and, as such, shall be subject to the provisions of this Article 5.

5.5 Confidentiality of Shire LOI. The existence and terms of the Shire LOI and any Shire Definitive Settlement Documents shall be Confidential Information subject to the provisions of this Article 5. MSRx shall not make any disclosure to the public or any Third Party (other than to its employees, officers, directors, members, managers, legal counsel and financial advisors) regarding the transactions contemplated by the Shire LOI or any Shire Definitive Settlement Documents or the terms and conditions thereof except to the limited extent that KemPharm is permitted to do so under the Shire LOI and/or the Shire Definitive Settlement Documents.

5.6 Intellectual Property of MSRx. KemPharm acknowledges and agrees, for itself and its Affiliates, that neither it nor any of its Affiliates shall have any rights, title or interests in, and shall not, and shall not permit others to, misappropriate, use, disclose or otherwise exploit, any Intellectual Property of MSRx in its or their possession or control, notwithstanding anything to the contrary contained in this Agreement or the Shire LOI (or the Shire Definitive Settlement Documents, if applicable) or the transactions contemplated hereunder or thereunder, or as a result of the disclosure or delivery to Shire or any of its Affiliates of any data, materials, reports or documents containing any Intellectual Property of MSRx required pursuant to the Shire LOI (or the Shire Definitive Settlement Documents, if applicable). KemPharm acknowledges and agrees that nothing contained in this Agreement, the Shire LOI (or the Shire Definitive Settlement Documents, if applicable) or the transactions contemplated hereunder or thereunder shall constitute or be construed as creating an express or implied grant of any rights, title, interests or licenses to KemPharm or Shire or their respective Affiliates of the Intellectual Property of MSRx and KemPharm hereby agrees to irrevocably waive, and agrees not to assert, any claim that KemPharm or any of its Affiliates has any rights, title or interests in or license to any of MSRx’s Intellectual Property.

5.7 Equitable Remedies. Each Party specifically recognizes that any breach by it of this Article 5 may cause irreparable injury to the other Party and that actual damages may be difficult to ascertain and, in any event, may be inadequate. Accordingly (and without limiting the availability of legal or equitable, including injunctive, remedies under any other provisions of this Agreement), each Party agrees that in the event of any such breach, the other Party shall be entitled to seek injunctive relief and such other legal and equitable remedies as may be available.

5.8 Survival. The obligations and prohibitions contained in this Article 5 shall survive the expiration or termination of this Agreement for a period of [***] years thereafter; provided, however, that Confidential Information which is a trade secret of the Disclosing Party if disclosed in writing or, if disclosed orally and confirmed within thirty (30) days in writing as being a trade secret of the Disclosing Party, shall be maintained in secret until such time as it no longer qualifies as a trade secret or until such time as Disclosing Party advises Receiving Party in writing that such information is no longer a trade secret.

INDEMNIFICATION

8.1 Mutual Indemnification. Each Party shall defend indemnify and hold harmless the other Party, including Affiliates and each of their respective officers, directors, shareholders, employees, representatives, agents, successors and assigns from and against all Claims of Third Parties, and all associated Losses, to the extent arising out of (a) a Party’s gross negligence or willful misconduct in performing any of its obligations under this Agreement, or (b) a material breach by a Party of any of its representations, warranties, covenants or agreements under this Agreement.

8.2 KemPharm Indemnification of Shire Complaint. In the event that Shire brings any Claim against MSRx in connection with the Acquired Assets other than solely as a result of a breach by MSRx of any obligation under this Agreement or in breach of the Shire Release, KemPharm shall indemnify, defend, and hold harmless, at KemPharm’s cost and expense, MSRx and MSRx’s Affiliates, and each of their respective officers, directors, shareholders, employees, representatives, agents, successors and assigns who are named therein (collectively, the “MSRx Parties”), in such Claim by Shire (a “Shire Claim”).

8.3 Procedure for Indemnification.

(A)

Notice. In the case of a Claim made by a Third Party (a “Third Party Claim”) as to which a Party (the “Indemnitor”) may be obligated to provide indemnification pursuant to this Agreement (including a Shire Claim), such Party seeking indemnification hereunder (“lndemnitee”) shall notify the Indemnitor in writing of the Third Party Claim (and specifying in reasonable detail the factual basis for the Third Party Claim and to the extent known, the amount of the Third Party Claim) reasonably promptly after becoming aware of such Third Party Claim; provided, however, that failure to give such notification will not affect the indemnification provided hereunder except to the extent the Indemnitor shall have been actually materially prejudiced as a result of such failure.

(B)

Defense of Claim. If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, then the Indemnitor may elect to assume the defense of any such Third Party Claim and any litigation resulting from such Claim. Both Parties agree to cooperate with the Party providing the defense in all material respects including the timing of requests for information and access to material necessary to the defense.

(C)

Assumption of Defense in the event of Default of Indemnitee. In the event the Indemnitor is not able to provide a defense, or elects not to provide a defense against any Third Party Claim, under this Section 8.3, notwithstanding anything to the contrary contained in this Agreement, an lndemnitee shall be entitled to assume the defense of any Third Party Claim and at its sole option provide the defense against the Third Party Claim. In such case of the Indemnitee providing the defense, the lndemnitor will be required, within thirty (30) days after receipt of written notice from the Indemnitee of the commencement or assertion of any such Third Party Claim, to provide to the Indemnitee all materials, correspondence, documents and information which may be useful in mounting a defense.

(D)

Settlement of Claims. If the Indemnitor acknowledges in writing its obligation to indemnify the Indemnitee for a Third Party Claim, the Indemnitee will agree to a reasonable settlement, compromise or discharge of such Third Party Claim that the Indemnitor may recommend that by its terms obligates the Indemnitor to pay the full amount of Losses (whether through settlement or otherwise) in connection with such Third Party Claim and unconditionally and irrevocably releases the Indemnitee completely from all Losses in connection with such Third Party Claim; provided, however, that, without the Indemnitee’s prior written consent, the Indemnitor shall not consent to any settlement, compromise or discharge (including, without limitation, the consent to entry of any judgment), and the Indemnitee may refuse to agree to any such settlement, compromise or discharge, that provides for injunctive or other non-monetary relief materially and adversely affecting the Indemnitee. If the lndemnitor acknowledges in writing its obligation to indemnify the Indemnitee against a Third Party Claim, the Indemnitee shall not (unless required by applicable law) admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnitor’s prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned).

(E)

Other Assumption of Defense. Notwithstanding anything to the contrary contained in this Agreement, an Indemnitee shall be entitled to assume the defense of any Third Party Claim with respect to the lndemnitee upon written notice to the lndemnitor in which case, the Indemnitor shall be relieved of liability under Section 8.l solely for such Third Party Claim and related Losses.

(F)

Direct Claims. Any Claim on account of any and all damages, deficiencies, defaults, assessments, fines, dues, penalties, costs, fees, liabilities, obligations, taxes, liens, losses, and expenses (including, without limitation, court costs, interest and reasonable fees of attorneys, accountants and other experts) incurred by or suffered by a Party which does not involve a Third Party Claim (a “Direct Claim”) shall be asserted by reasonably prompt written notice (stating in reasonable detail, the basis of such Claim and a reasonable estimate of the amount thereof) given by the Indemnitee to the Indemnitor. Except as otherwise stated in this Agreement, for a period of sixty (60) days from and after the receipt of the written notice (or such shorter period of time as otherwise set forth in this Agreement with respect to a specific Claim) the Parties shall attempt in good faith to resolve such Direct Claim. If the Parties are unable to resolve such Direct Claim, the Party seeking recourse may thereafter pursue any and all legal and equitable remedies at its disposal to enforce said Direct Claim.

ARTICLE 9

TERM AND TERMINATION

9.1 Term. This Agreement shall be deemed to commence on the Effective Date and, unless terminated earlier in accordance with the terms of this Agreement, shall continue until the completion or termination of all payments to MSRx of Value pursuant to Article 4 and Section 6.6 (the “Term”).

9.2 Accrued Rights; Surviving Obligations. Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination, relinquishment or expiration. Such termination, relinquishment or expiration shall not relieve any Party from obligations which are expressly or by implication intended to survive termination, relinquishment or expiration of this Agreement and shall not affect or prejudice any provision of this Agreement which is expressly or by implication provided to come into effect on, or continue in effect after, such termination, relinquishment or expiration.

9.3 Survival. The following provisions shall survive the termination of this Agreement: Article 5, Section 6.6, Article 8, Article 9 and Article 10, as well as any applicable definitions and general provisions. Remedies for breaches will also survive termination of this Agreement.

Should both Parties jointly agree that either of them is required to submit or obtain any such filing, registration or notification, they shall cooperate, each at its own expense, in such filing, registration or notification and shall execute all documents reasonably required in connection therewith.

In the event any such action shall be brought to enforce or interpret the terms of this Agreement in accordance with this Section 10.3, the Parties agree that such action will be brought in the State or Federal courts located in Delaware. Each of MSRx and KemPharm hereby irrevocably submits with regard to any action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of MSRx and KemPharm hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (c) to the fullest extent permitted by applicable law, that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, and (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

10.4 Assignment.

Re:	Collaboration and License Agreement with KemPharm, Inc.

Dear Xx. Xxxxxxx:

We refer to the Collaboration and License Agreement between MonoSol Rx, LLC (“MonoSol”) and KemPharm, Inc. (“KemPharm”) dated April 20, 2011, as it has and may be amended from time to time (the “Collaboration Agreement”). Pursuant to the Collaboration Agreement, MonoSol, among other things, has been granted a right of first refusal with regard to certain KemPharm amino acid conjugate products, including KP106 (“MonoSol’s ROFR”).

As you are aware KemPharm has entered into a Settlement Agreement (“Settlement Agreement”) and an Asset Purchase Agreement (the “APA”), a copy of each of which has been provided to MonoSol, pursuant to which KemPharm intends to sell to Shire LLC (“Shire”) certain KemPharm amphetamine amino acid conjugate products, including KP106, together with related intellectual property, documents, and other assets (as further defined in the APA, the “Acquired Assets”). In recognition of, and in accordance with, MonoSol’s ROFR and any other rights MonoSol may have under the Collaboration Agreement or any other agreement, arrangement or understanding with KemPharm relating to the Acquired Assets, the closing and transfer of the Acquired Assets to Shire is conditioned upon the non-exercise of MonoSol’s ROFR and the delivery to Shire of a copy of this letter agreement counter-signed by MonoSol.

Pursuant to this letter agreement in consideration to the payment MonoSol is to receive under the terms of the APA and the Manufacturing ROFN (defined below), Shire desires MonoSol to confirm its non-exercise of MonoSol’s ROFR and relinquish any other rights MonoSol has or may have with respect to the Acquired Assets, including, but not limited to, under the terms of the Collaboration Agreement or any other agreement, arrangement, or understanding with KemPharm.

By counter-signing below, MonoSol hereby: (i) consents to the immediate (notwithstanding the ninety (90) day closing period required under Section 6.2 of the Collaboration Agreement) transfer, sale and assignment of the Acquired Assets by KemPharm to Shire; (ii) acknowledges its non-exercise of MonoSol’s ROFR; (iii) terminates any present or future right to the Acquired Assets, including, but not limited to, any right to manufacture the Acquired Assets under Article 8 of the Collaboration Agreement; (iv) confirms that upon transfer to Shire, Shire will have no obligation to MonoSol to develop, commercialize, or otherwise exploit the Acquired Assets; and (v) waives its right to make any claim, argument or allegation contrary to, or inconsistent with, the foregoing (i), (ii), (iii); and (iv), and waives its right to make any claim, argument or allegation that the APA or the transaction contemplated therein, including, but not limited to, the transfer, sale and assignment of the Acquired Assets by KemPharm to Shire, is void, invalid, ineffective or otherwise unenforceable. MonoSol acknowledges that Shire is consummating the transactions contemplated by the APA in reliance upon the agreements, consents, and waivers set forth in this letter agreement.

Notwithstanding the foregoing, nothing contained in this letter agreement or in the Settlement Agreement or APA shall limit, waive or affect the rights of MonoSol under the Termination Agreement dated as of March 20, 2012 between MonoSol and KemPharm providing for the termination of the Collaboration Agreement subject to the terms and conditions set forth therein, a copy of which has been provided to Shire (the “Termination Agreement”) or to bring any claim or action against Shire with respect to any failure of Shire or its Affiliates (as defined in the APA) to perform or observe any covenant or agreement to be performed or observed by Shire pursuant to this letter agreement.

Shire agrees, for itself and its Affiliates, that neither it nor any of its Affiliates shall have any rights, title or interests in, and shall not, misappropriate, use, disclose or otherwise exploit, any of MonoSol’s Confidential Information, notwithstanding anything to the contrary contained in the Settlement Agreement or APA or in the transactions contemplated thereunder or the disclosure or delivery to Shire or any of its Affiliates of any data, materials, reports or documents containing any of MonoSol’s Confidential Information. Shire acknowledges and agrees that nothing contained in this letter agreement, the Settlement Agreement or the APA or the transactions contemplated herein or therein shall constitute or be construed as creating an express or implied grant of any rights, title, interests or licenses to Shire of MonoSol’s Confidential Information and Shire hereby agrees to irrevocably waive, and agrees not to assert, any claim that Shire or any of its Affiliates has any rights, title or interests in or license to any of MonoSol’s Confidential Information or MonoSol’s Intellectual Property (as defined in the APA). In the event that Shire or its Affiliates become, or anticipates that it or its Affiliates may become, legally compelled to disclose any of MonoSol’s Confidential Information, Shire will provide MonoSol with prompt notice so that MonoSol may seek a protective order or other appropriate remedy. If a full protective order or other appropriate remedy is not obtained, Shire will disclose only that portion of MonoSol’s Confidential Information which it remains legally compelled to disclose, and will exercise its reasonable efforts to obtain reliable assurance that confidential treatment will be accorded MonoSol’s Confidential Information.

For the purposes of this letter agreement, “MonoSol’s Confidential Information” shall mean any Confidential Information (as defined by APA), including Know-How (as defined by APA), of MonoSol disclosed to Shire pursuant to the Settlement Agreement or APA directly related to the manufacture, formulation, or composition of the Acquired Product solely in a oral film dosage form.

Shire specifically recognizes that any breach by it or any of its Affiliates of its obligations under this letter agreement regarding the Confidential Information of MonoSol may cause irreparable injury to MonoSol and that actual damages may be difficult to ascertain and, in any event, may be inadequate. Accordingly (and without limiting the availability of legal or equitable, including injunctive, remedies available to MonoSol), Shire agrees that, in the event of any such breach, MonoSol shall be entitled to seek injunctive relief and such other legal and equitable remedies as may be available.

Shire, on behalf of itself and its Affiliates and their respective predecessors, successors, administrators, assigns, agents, officers, employees, shareholders, directors, representatives and all other persons claiming by, through and under them (collectively, the “Shire Parties”), hereby releases and discharges MonoSol and each of its Affiliates, predecessors, successors, assigns, and each of its and their respective officers, directors, members, managers, administrators, agents, shareholders, employees, consultants, technical advisors, representatives, attorneys, business partners or collaborators (collectively, the “MonoSol Parties”), from any and all manner of debts, claims, causes of action (including, without limitation, those asserted in the complaints in the pending litigation between Shire and KemPharm as referenced in the Settlement Agreement), agreements, actions, suits, sums of money, demands, damages, liabilities, obligations, rights, or suits regarding such pending litigation or any acts, transactions, activities, facts, matters or omissions whatsoever, whether known or unknown, suspected or unsuspected, at law or in equity, whether based on actions or inactions, which any of the Shire Parties now owns or holds, or any at any time heretofore were owned or held by, that are or could have been the subject matter of such Pending Litigation (as defined in the Settlement Agreement), by reason of any act, matter, cause or thing whatsoever.

From and after the date of this letter agreement, Shire shall reimburse and indemnify each of the MonoSol Parties in respect of, and hold each of them harmless from and against, any and all Losses (as defined in the APA) suffered, incurred, or sustained by any of the MonoSol Parties or to which any of them becomes subject, resulting from, arising out of, or relating to:

(i) any failure of Shire or its Affiliates to materially perform or observe any covenant or agreement to be performed or observed by Shire pursuant to this letter agreement; and

(ii) any action or inaction of Shire or its Affiliates with respect to the Acquired Assets after the date of this letter agreement.

From and after the date of this letter agreement, MonoSol shall reimburse and indemnify each of the Shire Parties in respect of, and hold each of them harmless from and against, any and all Losses (as defined in the APA) suffered, incurred, or sustained by any of the Shire Parties or to which any of them becomes subject, resulting from, arising out of, or relating to any failure of MonoSol or its Affiliates to materially perform or observe any covenant or agreement to be performed or observed by MonoSol pursuant to this letter agreement.

In addition to the foregoing, Shire agrees that in the event Shire decided, at its sole discretion, to develop and/or commercialize a KP106 product in an oral film dosage form (a “KP106 Film”), that prior to entering into an agreement with a third party for the manufacture of such KP106 Film, Shire will first approach MonoSol (the “Manufacturing ROFN”). If MonoSol desires to manufacture the KP106 Film for Shire, Shire and MonoSol shall negotiate in good faith for a period of sixty (60) days such an agreement; provided that, if Shire and MonoSol are unable to enter into such an agreement Shire shall be free to have the KP106 Film manufactured by any third party, but shall have no right to use or permit any use of any of MonoSol’s Confidential Information in the manufacture of KP106 by any third party. The forging shall not in any way be deemed to create any obligation upon Shire to (i) develop, commercialize, or otherwise exploit the KP106 Film or any of the Acquired Assets, or (ii) negotiate with MonoSol regarding the manufacture of any product other than the KP106 Film.

The obligations and prohibitions of Shire and MonoSol set forth in the foregoing paragraphs shall survive the execution and delivery of this letter agreement and any expiration or termination of the Settlement Agreement or APA. Shire and MonoSol acknowledge that they are each agreeing to the terms and conditions set forth in this letter agreement, and the transactions contemplated hereunder and under the Settlement Agreement and APA, in reliance upon the agreements and covenants of the other set forth in this letter agreement.

We are providing this letter agreement to you on a confidential basis pursuant to Article 9 of the Collaboration Agreement, and this letter agreement shall be deemed “Confidential Information” under the Collaboration Agreement. This letter agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.

This letter agreement shall be governed by the laws of the State of Delaware, excluding its conflict of law rules, and both Shire and MonoSol hereby consent to the personal and exclusive jurisdiction of the United States District Court for the Southern District of New York to resolve any disputes arising under this Agreement. Notwithstanding the foregoing, if there is any dispute for which the United States District Court for the Southern District of New York does not have subject matter jurisdiction, the state courts in the State of New York and the City New York shall have jurisdiction.
