			“Change in Control” means the consummation of: (a) any merger, consolidation, business combination or sale of shares of stock other than in a direct issuance of shares of stock by a Party for fair value, that, if completed, will result in the stockholders of such Party prior to such transaction not having voting control of the surviving entity immediately after the transaction such that they, acting in concert with one another, could not elect a majority of the board of directors of the surviving entity; or (b) the sale, transfer, exchange or other disposition of all or substantially all of a Party’s assets or business relating to this Agreement (whether alone or in connection with a sale, transfer, exchange or other disposition of other assets or businesses of such Party).

d)

Section 2.2.2 is hereby amended and restated in its entirety as follows:

“2.2.2 R&D Rights of Third Parties.

     (a) Hyperion acknowledges that, prior to the Second Amendment Effective Date, Ucyclyd has granted Third Parties certain rights under the Distribution Agreements (as such term has been amended based on changes to Schedule 1.30 pursuant to this Second Amendment) with respect to research and development of the Products for uses within the Development Field (the “Pre-existing Rights”) and that Hyperion’s exclusive license in Section 8.2 is subject to such Pre-existing Rights.

     (b) From the Second Amendment Effective Date until the termination or expiration of the Development Term, Ucyclyd agrees not to grant (i) such Third Parties or any new Third Parties any further rights with respect to GT4P for uses within the Development Field; and (ii) distribution rights to the Marketed Products in the United States to a Third Party which will extend past the Closing Date. The Parties acknowledge and agree that because the Closing Date is based on the occurrence of certain events described in Section 3.1 (Purchase Rights), the exact date cannot be determined accurately and the Parties can rely only upon the dates on which the Closing is anticipated to occur based on the Development Plan in effect as of the Second Amendment Effective Date. Based on such Development Plan, the Closing Date is anticipated to be ***, which shall be the date relied upon with respect to the foregoing limitation; provided, however, that the date will be adjusted automatically if the events on which it is based change in the Development Plan or the events have not occurred by such date (as may be adjusted based on the foregoing) and the Parties agree to extend the date for a Closing under the Agreement.

     (c) During the Development Term, Ucyclyd reserves the right to grant Third Parties that currently or in the future distribute the Marketed Products the right to conduct research and development with respect to the Marketed Products for purposes of (i) obtaining Regulatory Approval for the Marketed Products in the applicable country or region, (ii) conducting post-marketing approval studies, and (iii) conducting any other studies or activities required by the applicable Regulatory Agency.

     (d) During the Development Term, Ucyclyd shall have the right to support investigator-sponsored activities or investigator-sponsored use of the Marketed Products for uses within the Development Field and will keep Hyperion apprised of such activities through the JSC meetings.

     (e) During the Development Term, Ucyclyd may support investigator-sponsored activities or investigator-sponsored use of GT4P only after allowing Hyperion to review such activities in advance and obtaining Hyperion’s approval of such activities.”

Second Amendment to Collaboration Agreement

e)

Section 2.2.3 is hereby amended and restated in its entirety as follows:

“R&D Rights Outside of the United States.

     (a) During the Development Term, Hyperion shall have the right to conduct research and development activities outside of the United States in support of Hyperion’s efforts to obtain Regulatory Approval in the United States, except in those jurisdictions where such research and development efforts would conflict with the rights granted to Third Parties pursuant to the Pre-existing Rights.

     (b) Subject to any Pre-existing Rights, during the Development Term, Hyperion shall have the right to propose to the JSC research and development activities outside of the United States in connection with obtaining Regulatory Approval for the Development Products outside of the United States. Ucyclyd shall advise Hyperion whether the conduct of any such activities would conflict with any rights granted to Third Parties that are in addition to the Pre-existing Rights. To the extent such proposed activities do not conflict with any Third Party rights, Hyperion shall have the right to perform such proposed activities. In the event that Hyperion conducts any research and development activities outside of the United States as permitted in this Section, Hyperion shall coordinate all such activities with Ucyclyd through the JSC during the Development Term.”

	f)		Schedule 1.30 (Distribution Agreements) is hereby amended and restated in its entirety in the new Schedule 1.30 attached to this Second Amendment.
	g)		Section 3.3.2 is hereby amended and restated in its entirety as follows:

     (iii) an Assignment and Assumption Agreement of all Assigned Agreements in the form attached to the Agreement as Exhibit 6 (Assignment and Assumption Agreement), which shall be countersigned by Ucyclyd and accompanied by all consents required from the applicable Third Parties to such Assigned Agreements to Hyperion as attachments to such Assignment and Assumption Agreement;

Second Amendment to Collaboration Agreement

     (iv) a Note in the form attached to the Agreement as Exhibit 9 (Note); and

     (v) a Security Agreement in the form attached to the Agreement as Exhibit 10 (Security Agreement).”

h)

Section 3.3.3 is hereby amended and restated in its entirety as follows:

“Payment of Purchase Price Amount.

     (a) The Purchase Price Amount shall be due and payable *** commencing on the first Business Day of the *** following the Closing Date and continuing on the first Business Day of *** thereafter in accordance with the terms and conditions of the Note. Hyperion’s obligations under the Note shall be secured by a first priority lien in and to the Collateral (as defined in the Security Agreement) in accordance with the terms and conditions of the Security Agreement.

     (b) From and after the Closing Date, Hyperion shall keep the Collateral in good order, and shall have sole responsibility for taking such steps as may be necessary, from time to time, to preserve all rights of Hyperion and Ucyclyd in the Collateral against Third Parties. Hyperion, at its place of business, shall keep accurate and complete books and records related to the Collateral in accordance with sound and generally accepted accounting principles applied on a basis consistent with prior years. Ucyclyd shall have the right at all times during business hours to inspect said books and records and make extracts therefrom.

     (c) Effective as of and after the Closing, Hyperion hereby covenants with and warrants to Ucyclyd that: (i) Hyperion is the sole owner of the Collateral free from any lien, security interest or encumbrance of any kind; (ii) Hyperion will not sell, lease or grant any further security interest in the Collateral or any part thereof, and will not part with possession of the same, except in the usual and ordinary course of Hyperion ‘s business; and (iii ) Hyperion will not use or permit the Collateral to be used in violation of any law or ordinance. Hyperion covenants, warrants and represents to Ucyclyd that all representations and warranties of Hyperion contained in this Section 3.3 shall be true at the time of the Closing Date and shall survive the execution, delivery and acceptance thereof by the Parties hereto and the closing of the transactions described herein or related hereto.”

i)

Section 4.1.1 is hereby amended and restated in its entirety as follows:

“Exclusive Commercialization Rights. Subject to the terms and conditions of this Agreement (including rights of Third Parties under the Distribution Agreements), on and following Closing, Hyperion shall have the sole and exclusive worldwide rights (even as to Ucyclyd) to Commercialize all Products for any and all indications (including any and all indications in the field of Hyperammonemia) which rights shall include the worldwide manufacture and supply of Products for use in all such Commercialization activities, provided that Hyperion complies with the terms and conditions set forth in Section 8.2.2 (Manufacturing Technology; Drug Master Files) regarding the manufacture and supply of Products. Hyperion shall be solely responsible for all costs and expenses in the Commercialization of Products including the supply and manufacture thereof.”

j)

Section 8.2.1 is hereby amended and restated in its entirety as follows:

“Product Technology and Developed Technology. Subject to the terms and conditions of the Agreement, Ucyclyd hereby grants to Hyperion an exclusive (except as to Ucyclyd

Second Amendment to Collaboration Agreement

as set forth in Section 2.2.6(a) (Transition of Development and Regulatory Program to Hyperion)), non-transferable (except as permitted by Section 16.14 (Assignment)), non-sublicenseable (except as necessary to conduct research and development activities outside of the United States in accordance with in Section 2.2.3 (R&D Rights Outside of the United States)), license under the Product Technology and the Developed Technology to research, develop, make, have made, import and use the Development Products to: (a) perform the activities under the Development and Regulatory Program in the Development Field in the Development Territory; and (b) perform research and development activities of such Development Products outside the Development Territory only pursuant to Section 2.2.3 (R&D Rights Outside of the United States), in each case for the duration of the Development Term. For clarity, the license granted under this Section 8.2.1 (Product Technology and Developed Technology) does not grant Hyperion the right to Commercialize, promote, market or sell the Development Products, and any rights to Commercialize, promote market or sell the Development Products in the Development Field arise only on and following Closing.”

For clarity, references to Ammonul HE have been removed since Hyperion no longer has rights to Ammonul HE prior to the Closing and any references to Development Products only refer to GT4P.

k)

Section 10.3(b)(i) is hereby amended and restated in its entirety as follows:

“(b) the Developed Technology developed, conceived, reduced to practice, originated, prepared, learned, generated, obtained or made by or on behalf of Hyperion, its Affiliates or their respective subcontractors in connection with the Agreement: (i) shall be performed, developed or manufactured in conformity with the Development Plan and all Legal Requirements, including current Good Laboratory Practices, Good Manufacturing Practices, and Good Clinical Practices, and all applicable FDA regulations, (ii) does not, to Hyperion’s actual knowledge as of the Second Amendment Effective Date, infringe upon the patents of a Third Party actually known to Hyperion; and (iii) does not, to Hyperion’s actual knowledge as of the Second Amendment Effective Date, infringe upon, or result from the misappropriation of, any other intellectual property rights of a Third Party.”

     (i) *** violation of any of the Compliance Requirements by Hyperion or any of its officers, directors or employees including a violation manifesting a wanton and reckless disregard for compliance;

     (ii) *** violation of any of the Compliance Requirements by a subcontractor of Hyperion that manifests a wanton and reckless disregard by Hyperion to require compliance by its subcontractors;

Second Amendment to Collaboration Agreement

For avoidance of doubt, the initial receipt of a Form 483, and efforts undertaken in good faith to respond thereto, by and of itself shall not constitute a violation for the purpose of this section.”

m)

Section 14.2.2 is hereby amended and restated starting with subsection (o) as follows:

“(o) the negligence, recklessness, or willful misconduct of a Hyperion Indemnitee with respect to the promotion, marketing, sale, manufacture, distribution, import or use of Product, including (i) unfair competition claims, (ii) product liability claims and (iii) any other claims arising out of failure to comply with Legal Requirements or Section 5.1(c) (General Compliance) by any Hyperion Indemnitee or any Third Party on behalf of a Hyperion Indemnitee; or

provided, however, that Hyperion shall not be required to indemnify any of the Ucyclyd Indemnitees to the extent that any Losses arise out of or result from: (x) the negligence, recklessness or willful misconduct of any Ucyclyd Indemnitee including failure by a Ucyclyd Indemnitee to comply with Legal Requirements; (y) any failure of a Ucyclyd Indemnitee to comply with the Agreement; or (z) any act or omission for which Ucyclyd is required to indemnify a Hyperion Indemnitee under Section 14.2.1 (Indemnification by Ucyclyd).”

n)

Section 16.14 is hereby amended and restated in its entirety as follows:

Both Parties agree that it shall be reasonable for Ucyclyd to withhold its consent to any Change in Control only if the Person that would become the successor to Hyperion’s interests under this Agreement pursuant to such Change in Control, at the time of the closing of the transaction resulting in the Change in Control:

(i) has a substantial business in the development and/or commercialization of products that compete with the products of Ucyclyd or Medicis Pharmaceutical Corporation or its other Affiliates;

(d) On or after the Closing, Hyperion may assign or transfer the Agreement (i) to an Affiliate or (ii) otherwise pursuant to (and only pursuant to) a Change in Control, in each case without the prior written consent of Ucyclyd.

(e) If Hyperion assigns or transfers the Agreement in accordance with Section 16.14(d) upon or after the Closing, then within *** after consummation of the transaction giving rise to such Change in Control, Hyperion shall pay Ucyclyd an amount equal to *** less any previously paid portion of the Purchase Price plus any accrued but unpaid interest.

(f) Ucyclyd shall have the right to assign the Agreement, or any right to receive payments hereunder, to an Affiliate or to a Third Party pursuant to a Change of Control at any time upon written notice to Hyperion but without the consent of Hyperion.

(g) Any rights granted to a Party under the Agreement shall inure to the benefit of any acquirer of, or successor in interest to, such Party.

No assignment shall release either Party from responsibility for the performance of any accrued obligation of such Party hereunder. This Agreement shall be binding upon and enforceable against the permitted successors, transferees or assignees of either of the Parties.”

If the Executive Sponsors cannot resolve such dispute within *** following Ucyclyd’s notification of the dispute, then such dispute shall be resolved as set forth in Article 15 (Dispute Resolution).
	(b)		Hyperion agrees that, during each Annual Period during the Term, with respect to each product for which Hyperion is obligated to make payments under Section 3.1 (General), Ucyclyd will receive minimum payments under Section 3.1 (General) equal to *** percent (***%) of the Minimum Sales Forecast, as amended pursuant to subsection (a) above if applicable (“Minimum Payments”). If the amounts paid to Ucyclyd under Section 3.1 (General) during an Annual Period with respect to each applicable product are less than the Minimum Payment for such Annual Period with respect to each applicable product, Hyperion shall pay Ucyclyd the difference between the Minimum Payments and the amounts paid within *** following the end of the applicable Annual Period. Any payments under Section 3.1 (General) that are in excess of any Minimum Payments due in an Annual Period shall not be applied against any future Minimum Payments that are or become due. The obligation to pay Minimum Payments shall continue with respect to each applicable product until such time as no payments remain under Section 3.3 (Duration of Ongoing Payment Obligations) with respect to each such Development Product.

	(c)		Prior to the Closing, all such payments as described in Sections 4(a) and (b) (Assumed Payments) above shall be in the form of reimbursements to Ucyclyd and shall be received by Ucyclyd from Hyperion no less than *** prior to the date such payments are due from Ucyclyd to such licensors. To the extent that Ucyclyd is invoiced by such licensors for services rendered by such licensors, Ucyclyd shall promptly forward such invoice to Hyperion and Hyperion shall have *** after receiving such invoice to submit such payment to Ucyclyd. Hyperion shall not be required to reimburse Ucyclyd for services rendered by the licensors that are in connection with a request by Ucyclyd.
