ARTICLE 2. GRANTS

2.1 License. Subject to the limitations set forth in this Agreement and Sponsor’s Rights, to the extent that it may lawfully do so, UNIVERSITY hereby grants to LICENSEE an exclusive, sublicensable, license under Patent Rights to make, use, sell, offer for sale, and import Licensed Products and an exclusive license to use Technology, in the Field within the Territory and during the Term. LICENSEE may extend such license to its Affiliates, provided that LICENSEE will be responsible for such Affiliates.

2.2 Sublicense.

(a) The license granted in Paragraph 2.1 includes the right of LICENSEE to grant Sublicenses to third parties during the Term, but only for as long as [***].

(b) With respect to Sublicense granted pursuant to Paragraph 2.2(a), LICENSEE shall:

(i) not [***] for the license grant under Sublicense [***] in a timely fashion, which [***];

(ii) to the extent applicable, include all of the rights of and obligations due to UNIVERSITY (and, if applicable, the Sponsor’s Rights) and contained in this Agreement;

(iii) promptly provide UNIVERSITY with a copy of each Sublicense issued which may be reasonably redacted; and

(iv) collect and guarantee payment of all payments due, directly or indirectly, to UNIVERSITY from Sublicensees and summarize and deliver all reports due, directly or indirectly, to UNIVERSITY from Sublicensees.

(c) Upon termination of this Agreement for any reason, UNIVERSITY, at its sole discretion, shall determine whether LICENSEE shall cancel or assign to UNIVERSITY any and all Sublicenses, provided, however, UNIVERSITY will not unreasonably withhold its permission allowing LICENSEE to assign to UNIVERSITY any Sublicenses, provided further, that if the Sublicensee requests an assignment, UNIVERSITY will accept such assignment of the Sublicense, provided (i) that the Sublicensee is in good standing upon termination of this Agreement; (ii) [***]; and (iii) to the extent UNIVERSITY is legally able to accept such assignment. In no case, however, will UNIVERSITY be bound by duties and obligations contained in any Sublicense that extends beyond the duties and obligations of the UNIVERSITY set forth in this Agreement.

ARTICLE 3. CONSIDERATION

3.1 Fees and Royalties. The parties hereto understand that the fees and royalties payable by LICENSEE to UNIVERSITY under this Agreement are partial consideration for the license granted herein to LICENSEE under Technology and Patent Rights. LICENSEE shall pay UNIVERSITY:

(a) a license issue fee of Twenty Thousand dollars (US$20,000), no later than [***] after the Effective Date. This Paragraph 3.1(a) will survive the termination, expiration or assignment of this Agreement.

(b) the following license maintenance fees per year are payable on the [***][***] of the Effective Date and annually thereafter on each anniversary; provided however, that LICENSEE’s obligation to pay this fee shall end on the date when LICENSEE is commercially selling a Licensed Product:


Maintenance Fee		Anniversary
[***]		[***]
[***]		[***]
[***]		[***]

	[]*	[]*
	[]*	[]*
	[]*	[]*

In the event LICENSEE is required to pay royalties to one or more third parties for patent rights necessary to make, use or sell Licensed Products, LICENSEE may deduct [***] from the earned royalties payable to UNIVERSITY for every [***] LICENSEE actually pays to said third parties; provided, however, in no event shall the amount payable to UNIVERSITY be less than [***] of the amount otherwise due.

LICENSEE shall be required to pay the following minimum annual royalties commencing on the first commercial sale of a Licensed Product:


Minimum Annual Royalty		Year(s)
[***]		[***]
[***]		[***]
[***]		[***]

(e) [***] of all Sublicense Fees received by LICENSEE from its Sublicensees that are not royalties; provided, however, that following (i) [***] or (ii) [***], whichever occurs first, the percentage of Sublicense Fees due to UNIVERSITY shall be reduced to [***].

All fees and royalty payments specified in Paragraphs 3.1(a) through 3.1(e) above shall be paid by LICENSEE pursuant to Paragraph 4.3 and shall be delivered by LICENSEE to UNIVERSITY as noted in Paragraph 10.1.

3.2 Patent Costs. LICENSEE shall reimburse UNIVERSITY all Patent Costs incurred in the Territory within [***]) days] following the date an itemized invoice is sent from UNIVERSITY to LICENSEE. [***]

(i) diligently develop, manufacture, and sell Licensed Products;

(ii) achieve the milestones described in Exhibit B; and

(iii) spend not less than [***] for the development of Licensed Products within [***] from the Effective Date, which includes the amounts that LICENSEE is paying to UNIVERSITY pursuant to a Sponsored Research Agreement currently being negotiated.

(b) If LICENSEE fails to perform any of its obligations specified in Paragraphs 3.3(a)(i)-(iii), UNIVERSITY shall have the right and option to either terminate this Agreement or change LICENSEE’s exclusive license under Patent Rights to a nonexclusive license. This right, if exercised by UNIVERSITY, supersedes the rights granted in Article 2. Notwithstanding the foregoing, if LICENSEE fails to meet a diligence provision for a Licensed Product despite having diligently pursued the provision at issue, as demonstrated in progress reports or other communication provided to UNIVERSITY or by receipt of notice from the FDA (or equivalent foreign regulatory agency, if applicable) of a delay or denial of approval for a Licensed Product, UNIVERSITY agrees to extend such milestone obligations with respect to the Licensed Product and discuss in good faith with LICENSEE about the extension period.

ARTICLE 4. REPORTS, RECORDS AND PAYMENTS

4.1 Reports.

(a) Progress Reports.

Beginning [***] after the Effective Date and within [***] after the end of each of LICENSEE’s fiscal years until the first commercial sale of a Licensed Product, LICENSEE shall furnish UNIVERSITY with a written report on the progress of its efforts during the immediately preceding fiscal year to develop and commercialize Licensed Products. The report shall provide a discussion, [***], of [***], provided that LICENSEE shall only be required to provide such sales projections after a BLA (or equivalent filing) has been made to a regulatory authority. LICENSEE’s fiscal year begins on January 1st.

(b) Royalty Reports.

After the first commercial sale of a Licensed Product anywhere in the world, LICENSEE shall submit to UNIVERSITY annual royalty reports on or before [***]. Each royalty report shall cover LICENSEE’s (and each Affiliate’s and Sublicensee’s) most recently completed calendar year and shall show:

(i) the date of first commercial sale of a Licensed Product in each country:

(ii) the gross sales and Net Sales during the most recently completed calendar year and the royalties, in US dollars, payable with respect thereto;

(iii) the number of each type of Licensed Product sold;

(iv) Sublicense Fees and royalties (“Sublicense Revenues”) received during the most recently completed calendar year in US dollars, payable with respect thereto;

(v) the method used to calculate the royalties; and

(vi) the exchange rates used.

If no sales of Licensed Products have been made and no Sublicense Revenues have been received by LICENSEE during any reporting period, LICENSEE shall so report. The reports referred to in this Paragraph 4.1(b) should be marked with the following title and case number: [***] Reports shall be submitted as an attachment to UC SAN DIEGO’s email address: [***].

4.2 Records & Audits.

(a) LICENSEE shall keep, and shall require its Affiliates and Sublicensees to keep, accurate and correct records of all Licensed Products manufactured, used, sold, offered for sale, and imported and Sublicensee Fees received under this Agreement. Such records shall be retained by LICENSEE for at least [***] following a given reporting period.

(b) At a mutually agreeable time, all records shall be available during normal business hours for inspection at the expense of UNIVERSITY by UNIVERSITY’s Internal Audit Department or by a Certified Public Accountant selected by UNIVERSITY (a “University Inspector”) and in compliance with the other terms of this Agreement for the sole purpose of verifying reports and payments or other compliance issues. Records reviewed remain subject to the provisions set forth in Paragraph 10.2.

Such University Inspector shall not disclose to UNIVERSITY any information other than information relating to the accuracy of reports and payments made under this Agreement or other compliance issues. In the event that any such inspection shows an underreporting and underpayment in excess of [***] for any [***] period, then LICENSEE shall pay the cost of the audit as well as any additional sum that would have been payable to UNIVERSITY had the LICENSEE reported correctly plus an interest charge at a rate of [***]. Such interest shall be calculated from the date the correct payment was due to UNIVERSITY up to the date when such payment is actually made by LICENSEE. For underpayment not in excess of [***] for any [***] period, LICENSEE shall pay the difference within [***] without interest charge inspection cost.

4.3 Payments.

(a) All fees, reimbursements and royalties due to UNIVERSITY shall be paid in United States dollars and all checks shall be made payable to [***], and sent to UNIVERSITY according to Paragraph 10.1 (Correspondence).

(b) Royalty Payments.

(i) Royalties shall accrue when [***].

(ii) LICENSEE shall pay earned royalties annually on or before each anniversary

of the Effective Date. Each such payment shall be for earned royalties accrued within LICENSEE’s most recently completed calendar year.

(c) Late Payments. In the event royalty, reimbursement and/or fee payments are not received by UNIVERSITY when due, LICENSEE shall pay to UNIVERSITY interest charges at a rate of [***], or the highest rate allowed by law, whichever is higher. Such interest shall be calculated from [***].

(d) Taxes. Taxes imposed by any governmental agency on LICENSEE on any payments to be made to UNIVERSITY by LICENSEE hereunder shall be paid by LICENSEE without deduction from any payment due to UNIVERSITY hereunder.

ARTICLE 5. PATENT MATTERS

5.1 Patent Prosecution and Maintenance.

(a) Provided that LICENSEE is reimbursing UNIVERSITY for its Patent Costs on a timely basis pursuant to Paragraph 3.2, UNIVERSITY shall diligently prosecute and maintain the United States and, if available, foreign patents, and applications in Patent Rights using counsel of its choice. For purposes of clarity, if LICENSEE is not current in reimbursing UNIVERSITY for such Patent Costs in accordance with the time period set forth in Paragraph 3.2, UNIVERSITY shall have no obligation to incur any new Patent Costs under this Agreement or to further prosecute Patent Rights or file any new patent applications under Patent Rights upon written notice to LICENSEE (such as email notices). UNIVERSITY shall provide LICENSEE with copies of all relevant documentation relating to such prosecution and an opportunity to review and provide comments relating thereto. LICENSEE shall keep this documentation provided by UNIVERSITY confidential. The

counsel shall take instructions only from UNIVERSITY, and all patents and patent applications in Patent Rights shall be assigned solely to UNIVERSITY. UNIVERSITY shall take into good faith consideration any comments provided by LICENSEE with respect to documentation relating to such prosecution and any actions recommended by LICENSEE to protect the Licensed Products contemplated to be sold by LICENSEE under this Agreement. UNIVERSITY shall in any event control all patent filings and all patent prosecution decisions and related filings (e.g., responses to office actions) shall be at UNIVERSITY’s final discretion (prosecution includes, but is not limited to, interferences, oppositions and any other inter partes or ex parte matters originating in a patent office).

(b) Should LICENSEE elect to terminate its reimbursement obligations with respect to any patent application or patent in Patent Rights in a specific country, LICENSEE shall have no further license with respect to such Patent Rights under this Agreement for such country. Non-payment of any portion of Patent Costs with respect to any application or patent may be deemed by UNIVERSITY as an election by LICENSEE to terminate its reimbursement obligations with respect to such application or patent. UNIVERSITY is not obligated at any time to file, prosecute, or maintain Patent Rights in a country, where, for that country’s patent application or patent LICENSEE is not paying Patent Costs, or to file, prosecute, or maintain Patent Rights to which LICENSEE has terminated its license hereunder.

5.2 Patent Infringement.

(a) If UNIVERSITY (based on actual knowledge of the licensing professional responsible for administering this Invention), or LICENSEE learns of potential infringement of commercial significance of any patent licensed under this Agreement, the knowledgeable party promptly will inform the other party of the infringement and provide evidence of infringement available to the knowledgeable party (“Infringement Notice”). In a jurisdiction where LICENSEE has exclusive rights under this Agreement, neither UNIVERSITY, nor LICENSEE will notify a third party (including the infringer) of infringement or put such third party on notice of the existence of any Patent Rights without first obtaining consent of the other. UNIVERSITY and LICENSEE agree to discuss and determine how best to proceed. If LICENSEE notifies a third party of infringement or puts such third party on notice of the existence of any Patent Rights regarding such infringement without first obtaining the written consent of UNIVERSITY and UNIVERSITY is sued for declaratory judgment (or its equivalent), UNIVERSITY will have the right to terminate this Agreement immediately, notwithstanding Paragraph 7.1. UNIVERSITY and LICENSEE will use diligent efforts to cooperate with each other to terminate such infringement without litigation. Subject to statutory deadlines, if such infringement has not ended within [***] of the effective date of the Infringement Notice, then LICENSEE may initiate suit (or earlier depending on an applicable statutory deadline to file); and, if such infringement has not ended within [***] of the effective date of the Infringement Notice, and LICENSEE has not initiated suit, then UNIVERSITY may initiate suit.

Notwithstanding the foregoing: (1) UNIVERSITY may not be joined in any suit without its prior written consent; (2) LICENSEE may not admit liability or wrongdoing on behalf of UNIVERSITY without its prior written consent; (3) Each party will cooperate with the other in litigation initiated under Paragraph 5.2, but at the expense of the party who initiated the suit; (4) If UNIVERSITY is joined in any suit under Paragraph 5.2, LICENSEE will pay all of UNIVERSITY’s costs; (5) If UNIVERSITY is a party to a suit under Paragraph 5.2, then the recovery to UNIVERSITY will be greater than or equal to [***] of net recoveries; (6) Any agreement made by LICENSEE for purposes of settling litigation or other dispute regarding Patent Rights will comply with the requirements of Paragraph 2.2 (Sublicense); and (7) If LICENSEE or UNIVERSITY (but not both) sues a third party for infringement of Patent Rights, then the non-suing party may not thereafter sue such infringer for the acts of infringement raised in the suit.

5.3 Patent Marking.

LICENSEE shall mark all Licensed Products made, used, sold, offered for sale, or imported under the terms of this Agreement, or their containers, in accordance with the applicable patent marking laws. LICENSEE shall be responsible for all monetary and legal liabilities arising from or caused by (a) failure to abide by applicable patent marking laws and (b) any type of incorrect or improper patent marking.

ARTICLE 6. EXPORT CONTROL AND REGISTRATION

6.1 Export Control. LICENSEE shall observe all applicable United States and foreign laws with respect to the transfer of Licensed Products, Technology, and related technical data to foreign countries, including, without limitation, the International Traffic in Arms Regulations and the Export Administration Regulations.

6.2 Governmental Approval or Registration. If this Agreement or any associated transaction is required by the law of any nation to be either approved or registered with any governmental agency, LICENSEE shall assume all legal obligations to do so. LICENSEE shall make all necessary filings and pay all costs including fees, penalties, and all other out-of-pocket costs associated with such reporting or approval process.

6.3 Preference for United States Industry. If LICENSEE sells a Licensed Product in the US, LICENSEE shall manufacture said product substantially in the US to the extent such is required under the applicable provisions of 35 U.S.C. §§200-212, unless a waiver is obtained from the appropriate governmental agency. UNIVERSITY agrees to provide all reasonable assistance to LICENSEE to apply for and obtain such a waiver.

ARTICLE 7. TERMINATION OR EXPIRATION OF THE AGREEMENT

7.1 Termination by UNIVERSITY.

(a) UNIVERSITY may terminate this Agreement if LICENSEE:

(i) is delinquent on any report or payment;

(ii) is not diligently developing and commercializing Licensed Product in accordance with obligations under Paragraph 3.3;

(iii) misses a milestone described in Exhibit B;

(iv) is in breach of any provision;

(v) provides any intentionally misleading and false report; or

(vi) files a claim including in any way the assertion that any portion of UNIVERSITY’s Patent Rights is invalid or unenforceable.

(b) Termination under this Paragraph 7.1 will take effect [***] after written notice by UNIVERSITY unless LICENSEE remedies the problem in that [***] period, provided that this cure period shall be extended for an additional [***] period if LICENSEE is working in good faith to remedy the problem.

7.2 Termination by LICENSEE.

(a) LICENSEE shall have the right at any time and for any reason to terminate this Agreement in whole or on a Licensed Product-by-Licensed Product, country-by-country basis, upon a [***] written notice to UNIVERSITY. Said notice shall state LICENSEE’s reason for terminating this Agreement.

(b) Any termination under Paragraph 7.2(a) shall not relieve LICENSEE of any obligation or liability accrued under this Agreement prior to termination or rescind any payment made to UNIVERSITY or action by LICENSEE prior to the time termination becomes effective. Termination shall not affect in any manner any rights of UNIVERSITY arising under this Agreement prior to termination.

7.3 Survival on Termination or Expiration. The rights and obligations under Paragraphs and Articles 2.2(c) (Sublicense), 3.1(a) (license issue fee), 4.2 (Records & Audits), 7.3 (Survival on Termination or Expiration), 8.1, 8.2(a) and 8.2(d) (Limited Warranty and Indemnification), 9.1 (Use of Names and Trademarks), 10.2(a)-(c) (Secrecy), 10.5 (Failure to Perform) and 10.6 (Governing Laws) shall survive the termination or expiration of this Agreement.

AGREEMENT FOR ALL CAUSES OF ACTION OF ANY KIND (INCLUDING TORT, CONTRACT, NEGLIGENCE, STRICT LIABILITY AND BREACH OF WARRANTY) EVEN IF UNIVERSITY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. ALSO, UNIVERSITY WILL NOT BE LIABLE FOR ANY DIRECT DAMAGES SUFFERED BY LICENSEE, SUBLICENSEES, JOINT VENTURES, OR AFFILIATES ARISING OUT OF OR RELATED TO PATENT RIGHTS TO THE EXTENT ASSIGNED, OR OTHERWISE LICENSED, BY UNIVERSITY’S INVENTORS TO THIRD PARTIES.

This indemnification will include, but will not be limited to, any product liability. Notwithstanding the foregoing, LICENSEE shall not be required to indemnify any Indemnitee to the extent such claim is due to the gross negligence or willful misconduct of an Indemnitee.

(b) LICENSEE, at its sole cost and expense, shall insure its activities in connection with the work under this Agreement and obtain, keep in force and maintain insurance as follows:
