2.7 Diligent Commercialization.

Licensee by itself or through its Affiliates and Sublicensees will use commercially reasonable efforts to make a Licensed Product commercially available in the Field within the Territory. Without limiting the foregoing, Licensee will

(a) maintain a bona fide, funded, ongoing and active research, development, manufacturing, regulatory, marketing or sales program (all as commercially reasonable) to make a Licensed Product commercially available to the public as soon as commercially practicable, and

(b) fulfill the following milestone events by the deadlines indicated:

Diligence Milestone Events		Deadlines
[***]			[***]
[***]			[***]
[***]			[***]
[***]			[***]
[***]			[***]

If the obligations under this Section 2.7 are not fulfilled, Licensor may treat such failure as a breach in accordance with Section 7.3(b). For the avoidance of doubt, initiation of a clinical trial means the dosing of the first patient in said clinical trial.

Notwithstanding the foregoing, if Licensee believes that, despite using commercially reasonably efforts, it will not achieve any Diligence Milestone Event set forth in this Section 2.7 by the relevant deadline, it may notify Licensor in writing thereof in advance of the deadline. Licensee shall include with such notice a reasonable explanation of the reasons for such failure. If Licensee so notifies Licensor and such explanation is acceptable to Licensor (in its reasonable discretion), or, in any event, if such failure to meet the Diligence Milestone Event is due to circumstances beyond Licensee’s reasonable control (such as patent infringement or regulatory issues), then the Parties shall negotiate in good faith an initial extension of the deadlines for said Diligence Milestone Event and all later Diligence Milestone Events (the “Initial Extended Milestones”) so that Licensee shall not be deemed to be in breach of achieving said Diligence Milestone Event by its deadline. In the event that Licensee believes that, despite using commercially reasonable efforts, it will not achieve one or more such Initial Extended Milestones, then Licensee may notify Licensor in writing thereof in advance of the relevant deadline and the Parties shall negotiate in good faith a second extension of deadlines for said Diligence Milestone Event and all later Diligence Milestone Events (the “Second Extended Milestones”) so that Licensee shall not be deemed to be in breach of achieving said Diligence Milestone Event by its deadline. Upon agreement of the Parties with respect to the deadlines for such Second Extended Milestones, Licensee shall make a non-creditable payment of one-half of the Milestone Fee of the Milestone Event corresponding to said Diligence Milestone Event.

However, in no event shall such adjustment result in royalty payments due to Licensor being reduced by more than [***]% of the royalty stated in Section 3.2 in any Contract Year.

3.4 Non-cash Consideration.

5.3 Late Payments.

Amounts that are not paid when due will accrue a late charge from the due date until paid, at a rate equal to [***]% per month (or the maximum allowed by law, if less).

5.4 Records.

For a period of [***] years after the Contract Quarter to which the records pertain, Licensee agrees that it and its Affiliates and Sublicensees will each keep complete and accurate records of their Sales, Net Sales, Milestone Fees, and Non-Royalty Sublicensing Consideration in sufficient detail to enable such payments to be determined and audited.

6.4 Foreign Filings.

If Licensee notifies Licensor prior to the filing of a patent application within the Patent Rights in a foreign country that Licensee wishes to not pay the cost of filing such patent application in such foreign country, then upon such notice said patent application or patent shall no longer be included in the Patent Rights and Licensee shall have no further rights thereto. Licensor shall have the right to make alternative arrangements with Licensee for upfront payment of foreign patent expenses.

6.5 Withdrawal from Paying Patent Costs.

If at any time Licensee wishes to cease paying for any costs for a particular Patent Right or for patent prosecution in a particular jurisdiction, Licensee must give Licensor at least 90 days prior written notice and Licensee will continue to be obligated to pay for the patent costs which reasonably accrue during said notice period.

A merger or other transaction in which the equity holders of Licensee prior to such event hold less than a majority of the equity of the surviving or acquiring entity shall be considered an assignment of the Agreement. Notwithstanding the foregoing, Licensee may assign this Agreement to an Affiliate of Licensee, if such assignment is for bona fide business purposes, or in connection with a merger, acquisition, change of control or sale of all or substantially all of its stock or assets to which this Agreement relates without any such written consent being required. For any permitted assignment to be effective, (a) the Licensee must be in good standing under the Agreement, (b) the Licensee must pay Licensor the assignment fee pursuant to Section 3.1(d), and (c) the assignee must assume in writing (a copy of which shall be promptly provided to Licensor) all of the Licensee’s interests,

Execution Version

participated in negotiating the provisions of the Agreement; therefore, both Parties agree that any ambiguity in the Agreement shall not be construed more favorably toward one Party than the other Party, regardless of which Party primarily drafted the Agreement.

Except where the context expressly requires otherwise: (a) the use of any gender herein will be deemed to encompass references to either or both genders, and the use of the singular will be deemed to include the plural (and vice versa); (b) the words “include”, “includes” and “including” will be deemed to be followed by the phrase “without limitation” and will not be interpreted to limit the provisions to which it relates; (c) the word “will” will be construed to have the same meaning and effect as the word “shall”; (d) any definition of, or reference to, any agreement, instrument or other document herein will be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein); and (e) any reference herein to any person or entity will be construed to include the person’s or entity’s successor and assigns.

19.3 Counterparts and Signatures.

The Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument.

In such event, the Party shall promptly provide the original signature page(s) to the other Party.

Execution Version

provisions hereof shall remain in full force and effect in such jurisdiction and shall be construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such other provisions in any other jurisdiction, so long as the essential essence of the Agreement remains enforceable.

19.8 Third Party Beneficiaries.

Nothing in the Agreement, express or implied, is intended to confer any benefits, rights or remedies on any entity, other than the Parties and their permitted successors and assigns.

19.10 Sovereign Immunity.

Nothing in the Agreement shall be deemed or treated as any waiver of Licensor’s sovereign immunity.
