(c) Notwithstanding the above, Connetics may grant one sublicense to InterMune (as defined in Section 3.1) under any or all of the rights granted in Sections 2.1 and 2.2(a) above without Genentech’s prior written approval. InterMune (but no other sublicensee of Connetics) may grant further sublicenses under Sections 2.1 and 2.2(a) to the extent that Connetics has the right to do so pursuant to the provisions of this Section 2.3 and Section 2.2(a). Connetics and InterMune shall give Genentech a copy of any sublicense agreement entered into by either of them with a third party pursuant to this Agreement as soon as reasonably possible after execution, provided that Connetics and InterMune may each redact from such copies text of information or provisions that are not relevant to this Agreement and the rights and obligations of the Parties hereunder. Genentech agrees to permit InterMune to perform Connetics’ rights and obligations under Section 2.2(b), (c) and (d), Section 2.5, Sections 3.1 through 3.8 and Article 4.0 of this Agreement (excluding matters related to any alleged breach of the Agreement, or dispute between the Parties concerning the performance of this Agreement, under such enumerated Sections and Article), to the extent such rights and obligations are sublicensed to InterMune by Connetics, and Genentech agrees to deal with InterMune in lieu of Connetics as if it were Connetics

hereunder for purposes of performance under such enumerated Sections and Article, provided that Connetics shall remain liable and responsible for performance of all of the obligations of Connetics and InterMune under this Agreement. In the event that Connetics sublicenses all of its rights under Section 2.1 and 2.2(a) to InterMune pursuant to a written sublicense which provides that InterMune (and not Connetics) shall make, have made, use, sell, offer for sale, import and develop Licensed Products in all Areas of the Field of Use in the Territory, then Genentech agrees to permit InterMune to also perform Connetics’ rights and obligations under Articles 5.0 and 6.0 and Sections 8.2 through 8.8 of this Agreement (excluding matters related to any alleged breach of the Agreement, or dispute between the Parties concerning the performance of this Agreement, under such enumerated Sections and Articles), and Genentech also agrees to deal with InterMune in lieu of Connetics as if it were Connetics hereunder for purposes of performance under such enumerated Sections and Articles, provided that Connetics shall remain liable and responsible for performance of all of the obligations of Connetics and InterMune under this Agreement. In the event that InterMune sublicenses any of its rights to a third party pursuant to this Agreement, such sublicensee shall not have the right to perform the rights and obligations of Connetics or InterMune under the Sections and Articles enumerated above, and Genentech shall not have any obligation to deal directly with such sublicensee. Notwithstanding the above provisions of this Section 2.3(c), with respect to any dispute concerning InterMune’s performance, or alleged breach by InterMune, of any applicable term of this Agreement, Genentech shall have the right to deal directly with Connetics, and to proceed either against InterMune or directly against Connetics, in Genentech’s sole discretion, to enforce this Agreement.

(d) In the event of the grant of any sublicense by Connetics (including such grant to InterMune) or by InterMune, the sublicensee shall be subject to all of the applicable obligations of Connetics hereunder. Connetics guarantees to Genentech the performance of Connetics’ applicable obligations hereunder by Connetics’ sublicensees and by InterMune’s sublicensees.

Efforts to adhere to the Dates of Completion as set forth in Exhibit E. Connetics shall notify Genentech in writing when it achieves a Clinical Development Milestone.

(b) From time to time, Connetics may suggest modifications to the Clinical Development Milestones based on new information. Such modifications shall be effective only as mutually agreed upon, in writing, by the Parties. Genentech shall consider such requested modifications in good faith and shall agree to any modifications that are reasonably necessary to achieve the overall objectives of the development of Licensed Product hereunder.

(c) In the event that Connetics determines that it will be unable to meet any Date of Completion for a Clinical Development Milestone due to an event within Genentech’s control, including without limitation, delay in the performance by Genentech of any of its obligations hereunder (e.g. the transfer of technology or materials, including the supply of Interferon Gamma-1B), Connetics shall give prompt notice to Genentech of such inability and shall specify the amount of delay Connetics believes resulted from such event within Genentech’s control. Unless Genentech disagrees in writing on reasonable grounds with the amount of such delay specified by Connetics, such Date of Completion will automatically be extended by the length of time of the delay. In the event Genentech disagrees in writing on reasonable grounds with the amount of delay specified by Connetics, the Parties shall negotiate a new Date of Completion in good faith.

(d) In the event that Connetics determines that it will be unable to meet any Date of Completion for a Clinical Development Milestone due to an event which would be considered a force majeure (as described in Section 12.9), Connetics shall give prompt written notice to Genentech of such inability and the length of the delay Connetics believes

resulted from such force majeure. Unless Genentech disagrees in writing on reasonable grounds with the length of such delay specified by Connetics, such Date of Completion will be automatically extended by such specified length of time of the delay. In the event Genentech disagrees in writing on reasonable grounds with the length of delay specified by Connetics, the Parties shall negotiate a new Date of Completion in good faith.

(e) In the event that Connetics determines that it will be unable to meet any Date of Completion for a Clinical Development Milestone for reasons other than (i) force majeure and/or (ii) an event within Genentech’s control, Connetics shall notify Genentech of such inability, identifying the nature of the inability with reasonable specificity and may ask Genentech for a reasonable extension of time in which to complete such Clinical Development Milestone. In Genentech’s sole discretion, Genentech may grant Connetics such an extension to complete such Clinical Development Milestone.

(f) Except as set forth in Sections 3.2(c) or 3.2(d) or in the event that Genentech shall have agreed to an extension of the time to complete a Clinical Development Milestone as set forth in Section 3.2(e), if Connetics fails to complete a Clinical Development Milestone by the corresponding Date of Completion with respect to one or more of the Areas of the Field of Use (other than in the dermatological Area of the Field of Use as described in Section 1.12(a) above) Genentech shall have the right to terminate this Agreement with respect to such Area(s) of the Field of Use, by providing Connetics written notice thereof, and the termination of the Agreement with respect to such Area(s) of the Field of Use shall be effective thirty (30) days after Connetics’ receipt of such notice unless such Clinical Development Milestone shall have been met prior to the expiration of such thirty (30) day period, and such termination shall be Genentech’s exclusive remedy for such failure

of Connetics to complete such Clinical Development Milestone. Upon such termination of the Agreement with respect to such Area(s) of the Field of Use: (i) Genentech shall automatically have all the rights set forth in Sections 11.3(a) and (b) solely with respect to such Area(s) of the Field of Use; and (ii) any sublicense(s) granted by Connetics with respect to such Area(s) of the Field of Use shall not automatically terminate, but instead, Genentech shall have the option to either terminate or continue this Agreement with respect to such Area(s) of the Field of Use with such sublicensee(s).

8.0 Up-front Payment, Milestone Payments and Royalties

In consideration for the licenses granted to Connetics by Genentech pursuant to Section 2.0 above, Connetics shall make the following payments to Genentech:

8.1 Up-front Payment. Connetics shall issue to Genentech upon the Original Closing Date (as defined in the Stock Agreement) shares of Connetics Common Stock (“Original Issuance Shares” as defined in the Stock Agreement) with a fair market value equal to two million dollars ($2,000,000), on the terms and conditions set forth in the Stock Agreement. If, on the Second Closing Date (as defined in the Stock Agreement), the aggregate market value of the Original Issuance Shares (based on the Second Issuance Price (as defined in the Stock Agreement)) is less than four million dollars ($4,000,000), Connetics shall issue to Genentech upon the Second Closing Date the number of additional shares of Connetics Common Stock (the “Second Issuance Shares,” as defined in the Stock Agreement) equal to the lesser of: (i) the number of shares necessary to increase the aggregate market value of the Original Issuance Shares (based on the Second Issuance Price) plus the Second Issuance Shares (based on the Second Issuance Price) to four million dollars ($4,000,000) or (ii) the number of shares necessary to increase the aggregate number of the Company’s shares of Common Stock held by Genentech (exclusive of any shares that Genentech has purchased from parties other than the Company) to 9.9% of the Company’s total outstanding shares of Common Stock as of the close of business on the third trading day before the Second Closing Date, on the terms and conditions set forth in the Stock Agreement. In lieu of all or any portion of the Second Issuance Shares that the Company is obligated to issue to Genentech on the Second Closing Date, the Company may elect to pay

Genentech the cash value of such Second Issuance Shares (based on the Second Issuance Price). The Original Closing and the Second Closing of the stock issuances shall take place as described in the Stock Agreement. In the event that Connetics does not issue to Genentech all of the Second Issuance Shares or the cash value of the Second Issuance Shares, Genentech may, in addition to other remedies available to it by law or in equity, immediately terminate this Agreement and the licenses granted to Connetics hereunder. Such termination by Genentech of the Agreement and the licenses hereunder does not discharge Connetics’ obligation to issue all of the Second Issuance Shares or to pay to Genentech the cash value of the Second Issuance Shares. The up-front payment shall not be creditable against any royalty payments owed by Connetics under Sections 8.3 and 8.4 below.

8.2 Milestone Payments for Licensed Products. Connetics shall make the following cash milestone payments to Genentech:

(a) *** within thirty (30) days following the dates on which each of the first three (3) NDA’s or BLA’s for a Licensed Product is filed with the FDA by Connetics for a new indication in the Field of Use; provided however, that such milestone payments shall not be paid upon the filing of a NDA or BLA for an osteopetrosis or atypical mycobacterial infection indication.

(b) *** within thirty (30) days following the date Connetics receives FDA clearance of each new indication for a Licensed Product for commercial sale in the United States; provided however, that such milestone payment shall not be paid upon receipt of FDA clearance for an osteopetrosis or atypical mycobacterial infection indication.

***	Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

(d) *** within thirty (30) days following the first date Connetics’ aggregate Net Sales of all Licensed Products in the Territory exceed *** in any calendar year.

Notwithstanding the foregoing, upon the expiration or revocation of the last remaining issued patent within the Genentech Patent Rights during the term of this Agreement, each of the milestones payments set forth in (a)-(d) above thereafter shall be reduced by fifty percent (50%). Milestone payments shall not be creditable against any royalty payments owed under Sections 8.3 and 8.4 below.

8.3 Royalties. Connetics shall pay Genentech the following royalties on Net Sales of Licensed Products by Connetics and its sublicensees:

(a) For annual aggregate Net Sales of all Licensed Products in the Territory of up to three million seven hundred thousand dollars ($3,700,000), a royalty rate equal to *** of such Net Sales.

(b) In addition to the payment of the royalty rate specified in (a) above, for annual aggregate Net Sales of all Licensed Products in the Territory exceeding three million seven hundred thousand dollars ($3,700,000), a royalty rate equal to *** of such Net Sales exceeding $3,700,000.

(c) The above royalties shall be payable until the later of: (i) the expiration or revocation of the last remaining issued patent within the Genentech Patent Rights or (ii) twenty (20) years from the Effective Date of this Agreement. Notwithstanding the

***	Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

foregoing, upon the expiration of the last to expire issued patent within the Genentech Patent Rights during the term of this Agreement, thereafter each of the royalty rates set forth in (a) and (b) above shall be reduced by fifty percent (50%).

8.4 Third-Party Royalties. If Genentech or Connetics is required to pay any third party a royalty due to the manufacture, use, sale, offer for sale or importation of a Licensed Product in the Territory for or by Connetics or its sublicensees, Connetics shall be responsible for the payment of *** of such third-party royalty, provided however, that Connetics may deduct from the royalties payable to Genentech under Section 8.3 above *** of such third party royalties incurred only due to use patents in the Field of Use in the Territory, up to a maximum total deduction of *** percentage points from the royalties payable by Connetics to Genentech under Section 8.3. For purposes of clarification, such deductions shall not apply to any benchmark payment under the *** License made by Connetics pursuant to Section 5.2(c) above. Attached hereto as Exhibit G is a list of all such royalty obligations to third parties known to Genentech as of the Effective Date without diligent search. No later than thirty (30) days from the Effective Date, Genentech shall complete a reasonable internal investigation of its records and update Exhibit G, as necessary, to accurately reflect all such royalty obligations to third parties to the best of Genentech’s knowledge; provided however, Connetics acknowledges that Genentech has no obligation to conduct due diligence or any investigation with respect to third party patent rights related to Licensed Products. Genentech shall notify Connetics in writing during the term of this Agreement if it becomes aware of any additional Genentech third party royalty obligations.
