PAYMENT OF PATENT COSTS 

4.1    Prosecution by Caltech. Caltech shall use reasonable efforts, consistent with its
normal practices, to: (a) prosecute any and all patent application(s) included in the Exclusively Licensed Patent Rights; and (b) file and prosecute Improvement Patent Rights licensed hereunder for which Caltech or Licensee deems it
beneficial to obtain additional coverage, provided that Licensee is reimbursing patent expenses in accordance with Sections 4.4 and 4.5. Licensee may 

  
 -7- 













 
recommend patent counsel for this purpose. Caltech shall permit Licensee to review and request modifications on all patent applications and claims made therein, and Caltech shall make reasonable
efforts to implement modifications thereto as may be requested by Licensee prior to filing. 
 4.2    Election of
Improvements. With respect to filings pursuant to Section 4.1(b) heroin above, Caltech shall promptly disclose such Improvements to Licensee, and Licensee shall elect within thirty (30) days whether such Improvements shall
be included within the Improvement Patent Rights, at its expense. Caltech will have no obligation to prosecute patent applications that may constitute Improvements that are not elected by Licensee. Upon written election by Licensee, the Parties will
amend, in a timely manner, Exhibit A hereto to include such Improvements within the Exclusively Licensed Patent Rights. 

4.3    Prosecution by Licensee. If Caltech declines to file, prosecute or maintain a patent or patent
application in the Exclusively Licensed Patent Rights or Improvement Patent Rights, then Licensee may elect to assume responsibility for such filing, prosecution or maintenance at its expense in Caltech’s name, with Caltech remaining the client
of record with the prosecuting attorney(s). Licensee shall fully cooperate with any and all other licensees, if any, of the patent or patent application. Caltech agrees to fully cooperate with Licensee in filing, prosecuting, and maintaining any
such patent applications and patents, and Caltech agrees to execute any documents as shall be necessary for such purpose, and not to impair in any way the patentability of any of the foregoing. 

4.4    Past Patent Costs. Licensee shall reimburse Caltech for all reasonable expenses (including
attorneys’ fees) incurred by Caltech prior to the Effective Date for the filing, prosecution and maintenance, interference or reexamination proceedings, of the Exclusively Licensed Patent Rights and Improvement Patent Rights. All amounts owed
under this Section 4.4 shall be due on or before April 30, 2016. Past patent costs as of the Effective Date are approximately [***]. Promptly following the Effective Date, Caltech shall provide Licensee with an invoice for the past patent
costs reimbursable by Licensee, including copies of Caltech’s records evidencing such past patent costs. 

  
 -8- 













 4.5    Ongoing Patent Costs. Licensee shall
reimburse Caltech for all fees and costs relating to ongoing filing, prosecution and maintenance, interference or reexamination proceedings of the Exclusively Licensed Patent Rights and Improvement Patent Rights that are not included in
Section 4.4 above. Such reimbursement shall be made within thirty (30) days of receipt of Caltech’s invoice. Should Licensee wish to terminate its license to any particular patent application or patent, Licensee may elect to do so by
providing written notice to Caltech at least sixty (60) days in advance. Licensee is responsible for all patent costs incurred up until the date of its election and Licensee’s subsequent reimbursement obligations of the ongoing patent
costs with respect to said patent application or patent will be terminated. Upon such election, Caltech may, at its option, continue such prosecution or maintenance, although any patent or patent application resulting from such prosecution or
maintenance will thereafter no longer be subject to the licenses granted in Section 2.1 hereunder. In the absence of proper election as described above, non-payment of any portion of patent costs, whether
to Caltech or directly to the prosecuting law firm will be considered monetary breach pursuant to Section 10.2. 

4.6    Foreign Patent Applications. Caltech shall file and prosecute foreign regional and national
patent applications at the request of Licensee, provided that Licensee is reimbursing patent expenses in accordance with Sections 4.4 and 4.5. Caltech may require Licensee to make an advance payment on anticipated foreign patent expenses. In such
cases, Licensee will be provided a quote for the expenses, and Licensee shall make an advance payment on the anticipated expenses within thirty (30) days before the patent applications are filed or patent prosecution actions are due. 

ARTICLE 5 
 CONSIDERATION

 5.1    Timing and Computation. All royalties hereunder (except for annual minimum
royalties) shall be computed on a quarterly basis for the quarters ending March 31st, June 30th, September 30th, and December 31st of each calendar year. Royalties for each such quarter shall be due and payable within seventy-five (75) days after the
end of such quarter. 
 5.2    License Issue Fee. Licensee shall pay to Caltech a License Issue Fee
in the amount of [***]. The License Issue Fee is nonrefundable and is due 

  
 -9- 













 
fourteen (14) days from the complete execution of this Agreement. 

5.3    Royalty on Valid Claims. For any country in which the Exclusively Licensed Patent Rights
include a Valid Claim where the Licensed Products are made, used, or sold, Licensee shall pay Caltech a royalty of [***] of Net Revenues. Royalties due under this Section 5.3 shall be payable on a country-by-country and Licensed Product-by-Licensed Product basis until the expiration of the last-to-expire issued Valid Claim covering such Licensed Product in such country. 

5.4    Royalty on Technology. For any country in which the Exclusively Licensed Patent Rights do not
include a Valid Claim, Licensee shall pay Caltech a royalty of [***] of Not Revenues for a period of seven (7) years from a first commercial sale. 

5.5    Bundled Products and Services. In the event that Licensed Products are sold,
licensed, distributed or used in combination with one or more other products or services which are not Licensed Products, the Net Revenues for such combination products will be calculated on a country-by-country basis by multiplying actual net sales (calculated on the basis as if they were Net Revenues) of such combination products by the fraction A/(A+B) where A is the average invoice price,
during the relevant quarterly period, of the Licensed Product when sold or licensed separately by Licensee or an Affiliate, and B is the average invoice price during such period of any other product(s) or services in the combination when sold or
licensed separately by Licensee or an Affiliate. If the products or services in the combination that are not Licensed Products have not been sold or licensed separately by Licensee or a Affiliate in the relevant quarterly period, Net Revenues shall
be calculated by multiplying actual net sales (calculated on a basis as if they were Net Revenues) of such combination products by the fraction A/C where A is the average invoice price, during the last quarterly period, of the Licensed Product when
sold or licensed separately and C is the average invoice price of the combination product during such period. If the Licensed Product has not been sold or licensed separately by Licensee or a Affiliate in the last quarterly period, regardless of
whether the combination product without the Licensed Product is sold or licensed separately, Net Revenues shall be calculated as in the 

  
 -10- 













 
immediately preceding sentence except that A shall be the total manufacturing cost of the Licensed Product and C shall be the total manufacturing cost of the combination. 

5.6    Royalty on Sublicensing Revenue. Licensee shall pay Caltech [***] of the Sublicensing Revenue.

 5.7    License Maintenance Fees; Minimum Annual Royalties. A license maintenance fee of [***] is
due to Caltech one year from the Effective Date and each anniversary thereof prior to the first commercial sale of a lens Licensed Product. A minimum annual royalty of [***] is due to Caltech each anniversary of the Effective Date following the
first commercial sale of a Licensed Product. Any royalties paid under Sections 5.3, 5.4, 5.5, and 5.6 for the one-year period preceding the date of payment of the minimum annual royalty shall be creditable
against the annual minimum. Caltech shall have the right to terminate this Agreement pursuant to Section 10.2 (Termination for Monetary Breach) for failure to pay such minimum annual royalty. 

5.8    Third Party Royalty Offset; No Multiple Royalties. If Licensee or an Affiliate is required to
make any payment (including, but not limited to, royalties or other license fees) to one or more third parties to obtain a patent license in the absence of which it could not legally make, import, use, sell, or offer for sale Licensed Products in
any country, and Licensee provides Caltech with reasonably satisfactory evidence of such third-party payments, [***] of such third-party payments shall be creditable against royalties owed to Caltech hereunder, provided that in no one year shall the
aggregate of all such expenses be credited against more than [***] of royalty payments to Caltech. Any greater amount of such expenses may be carried over and credited against royalties owed in future years, subject in every case to the [***] annual
cap for that year. Licensee shall not be required to pay multiple royalties under this Agreement and the existing Exclusive License Agreement between Caltech and Licensee dated November 20, 2003 (the “2003 Agreement”) on the same Net
Revenues. In the event that Licensee or its Affiliate or Sublicensee sells any Licensed Product for which royalties would be due under this Agreement and the 2003 Agreement, the royalties thereon shall be allocated between this Agreement and the
2003 Agreement based upon the 

  
 -11- 













 
relative value of the licenses granted under such agreements with respect to the applicable Licensed Product, as reasonably determined by Licensee. 

5.9    Currency Conversion. For the purpose of determining royalties payable under this Agreement,
any royalties or other revenues Licensee receives from Sublicensees in currencies other than U.S. dollars and any Net Revenues denominated in currencies other than U.S. dollars shall be converted into U.S. dollars according to the noon buying rate
of the Federal Reserve Bank of New York on the last business day of the quarterly period for which such royalties are calculated. 

5.10    Recordkeeping and Audits. Licensee shall keep complete and accurate production and accounting
records relating to commercialization (including via sublicensing) of Licensed Products for three (3) years following the end of the calendar year to which they pertain. Caltech shall be entitled to appoint an independent CPA to periodically
audit such records, upon reasonable advance notice and during Licensee’s normal business hours, to determine Licensee’s compliance with the provisions of this Article 5. Licensee shall reimburse Caltech one hundred percent (100%) of any
unpaid royalties resulting from any noncompliance discovered as a result of any such audit; and Licensee shall also pay Caltech a late payment fee of one percent (1%) per month of the entire amount of any underpayment. Such audits shall be at
Caltech’s expense, and shall occur no more than once annually, except that in the case of any underpayment exceeding ten percent (10%) of the amount actually paid: (a) Licensee shall reimburse Caltech for the cost of such audit; and
(b) Caltech shall be entitled to conduct additional quarterly audits, at Licensee’s expense, until any such audit demonstrates that Licensee is in compliance with its obligations. Licensee must flow this requirement down to all
Sublicensees. 
 5.11    Royalty Reports. For so long as royalties are payable under this
Agreement, Licensee shall provide a royalty report in writing to Caltech on or before the payment due date for the applicable quarter in accordance with Section 5.1. The report shall include, for all Licensed Products that are sold or otherwise
distributed by Licensee, Affiliates, and each Sublicensee, on a country-by-country basis:

(f)    royalties on Net Revenues due to Caltech; 

(g)    Sublicensing Revenue, including supporting data; 

(h)    foreign currency conversion rate and calculations (if applicable) and total royalties due; and 

(i)    names and contact information for all Sublicensees having a sublicense or option therefor any time during the
particular royalty period. 
 Each such report shall also set forth an explanation of the calculation of the royalties payable hereunder and be accompanied
by payment of the royalties shown by said report to be due Caltech. 
 ARTICLE 6 

ASSIGNMENT AND TRANSFER 

6.1    “Assign” (including all variations thereof) shall mean to transfer, including Assignment of rights

royalty in lieu of an assignment fee, Caltech and Licensee agree to amend this Agreement in good faith to address the royalty considerations prior to the Assignment of this Agreement. 

6.6    After the Assignment. Upon a permitted Assignment by Licensee of this Agreement
pursuant to this Article, Licensee will be released of liability under this Agreement and the term “Licensee” in this Agreement will mean the Assignee. 

ARTICLE 7 
 DUE DILIGENCE

 7.1    Commercialization. Licensee agrees to use commercially reasonable efforts to
commercially introduce and reasonably fulfill market demand for Licensed Products in the Field as soon as practical. Licensee shall be deemed to have satisfied its obligations under this Section 7.1 if Licensee has an ongoing and active research,
development or marketing program, directed primarily toward commercial production, use, and sale of one or more Licensed Products. Any efforts of Licensee’s Affiliates or Sublicensees shall be considered efforts of Licensee for the sole purpose
of determining Licensee’s compliance with its obligations under this Section 7.1. 

7.2    Reporting. On each yearly anniversary of the Effective Date, Licensee shall issue to Caltech a
detailed written report on its progress in introducing commercial Licensed 

  
 -14- 













 
Product(s). The report will be considered confidential information of Licensee subject to Article 11. 

7.3    Failure to Commercialize. If Licensee is not fulfilling its obligations under Section 7.1
with respect to the Field, and Caltech so notifies Licensee in writing, Caltech and Licensee shall negotiate in good faith any additional efforts to be taken by Licensee. If the Parties do not reach agreement within thirty (30) days of
Caltech’s written notice, Caltech may terminate this Agreement pursuant to Article 10. 
 ARTICLE 8 

LITIGATION 

8.1    Enforcement. Both Caltech and Licensee agree to promptly notify the other in writing should
either party become aware of possible infringement by a third party of the Exclusively Licensed Patent Rights or Improvement Patent Rights. Upon notice and exchange of evidence of such infringement, Licensee and Caltech shall meet and confer within
thirty (30) days to discuss how best to proceed with enforcement. During that meeting, Caltech may request that Licensee take steps to enforce the Exclusively Licensed Patent Rights or Improvement Patent Rights. If Licensee does not, within
ninety (90) days of such request, elect to file an action against the alleged infringer in the Field, Caltech will have all rights required by law to initiate an enforcement action in Caltech’s name at Caltech’s expense. Licensee
shall be entitled to control any such action initiated by it, but will keep Caltech apprised of the status of such action or suit, and will consult with Caltech should any issues arise in litigation that may affect Caltech or other Caltech
licensees. If Caltech is. required by law to join in such an action, or is subject to discovery requests in such an action, it will do so provided that: (a) Caltech will be represented by outside counsel of its choice; and (b) Licensee
shall reimburse Caltech for all reasonable out-of-pocket expenses (including Caltech’s outside counsel) and all reasonable internal Caltech expenses in connection
with the action. Licensee may take appropriate action to terminate or prevent the infringement; provided, however that Licensee may not bring an action against an accused infringer without prior written approval of Caltech, where approval will not
be unreasonably withheld, delayed or conditioned, and provided, further, that Caltech shall have the right to withhold such approval only if Caltech reasonably establishes and confirms to Licensee in writing, that withholding such approval would
materially further a substantial 

  
 -15- 













 
purpose of Caltech relevant to its non-profit status, academic mission and reputation. Caltech shall notify Licensee in writing within thirty
(30) days of receiving Licensee’s request for approval, if Caltech elects to withhold such approval (such notice a “Disapproval Notice”). Failure by Caltech to provide a Disapproval Notice within such thirty (30) day period
shall be deemed approval. In the event that Caltech provides a Disapproval Notice, Licensee shall have no obligation to pay any royalties on any Net Revenues made during the period from the Disapproval Notice until the earlier of (A) the date,
if any, that Caltech subsequently grants an approval for Licensee to bring such action against an accused infringer or (B) the date such infringement ceases. Caltech further agrees that if a Disapproval Notice is provided by Caltech, Caltech
will at Licensee’s request cooperate with Licensee in good faith, using diligent efforts, in connection with Licensee’s efforts to abate the subject infringement activity via alternative dispute resolution means that do not involve
litigation. Where settlement terms with an accused infringer requires any admission or forbearance of any right on the part of Caltech, Licensee may not enter into a settlement agreement with an accused infringer without prior written approval of
Caltech, where approval will not be unreasonably withheld, delayed or conditioned. 
 8.2    Other Defensive
Litigation. If a declaratory judgment action alleging invalidity, unenforceability or non-infringement of any of the Exclusively Licensed Patent Rights or Improvement Patent Rights is brought
against Licensee and/or Caltech, Licensee shall have the first right to control the defense of such action at its own expense. Caltech may elect to control the defense of such action if Licensee declines to do so, and if Caltech so elects it shall
bear all the costs of the action and shall make settlements only with the advice and written consent of Licensee. If mutually agreed between the Parties, Caltech may also undertake the defense of any interference, opposition or similar procedure
with respect to the Exclusively Licensed Patent Rights or Improvement Patent Rights, providing that Caltech bears all the costs thereof and makes settlements only with the advice and written consent of Licensee. 

8.3    Cooperation. In the event either party takes control of a legal action or defense pursuant to
Sections 8.1 or 8.2 (thus becoming the Controlling Party), the non-controlling party shall fully cooperate with and supply all assistance reasonably requested by the Controlling Party, including by:
(a) using commercially reasonable efforts to have its employees consult and testify when requested; (b) making available relevant records, papers, information, samples, 

  
 -16- 













 
specimens, and the like; and (c) joining any such action in which it is an indispensable party. The Controlling Party shall bear the reasonable expenses (including salary and travel costs)
incurred by the non-controlling party in providing such assistance and cooperation. The Controlling Party shall keep the non-controlling party reasonably informed of the
progress of the action or defense. If the non-controlling party is not required by law to join the action, that party shall nevertheless be entitled to participate in such action or defense at its own expense
and using counsel of its choice. As a condition of controlling any action or defense involving the Exclusively Licensed Patent Rights or Improvement Patent Rights pursuant to Sections 8.1 or 8.2, Licensee shall use commercially reasonable efforts to
preserve the validity and enforceability thereof. 
 8.4    Settlement. If Licensee controls any action or
defense under Section 8.1 or 8.2, then Licensee shall have the right to settle any claims thereunder, but only upon terms and conditions that are reasonably acceptable to Caltech.. Should Licensee elect to abandon such an action or defense
other than pursuant to a settlement with the alleged infringer that is reasonably acceptable to Caltech, Licensee shall give timely advance notice to Caltech who, if it so desires, may continue the action or defense. 

8.5    Recoveries. Any amounts paid by third parties to Caltech or Licensee as the result of an action or
defense pursuant to Sections 8.1 or 8.2 (including in satisfaction of a judgment or pursuant to a settlement) shall first be applied to reimbursement of the unreimbursed expenses (including attorneys’ fees and expert fees) incurred by each
party. In the event that Caltech is the Controlling Party, the remainder shall be retained by Caltech. In the event that Licensee is the Controlling Party, any remainder shall be divided between the Parties as follows: 

(a)    To the extent the amount recovered reflects Licensee’s lost profits or royalties, Licensee
shall retain the remainder, less the amount of any royalties that would have been due Caltech under Article 5 on account of such lost profits or royalties, provided that Licensee shall in any event retain at least [***] of the remainder; and 

  
 -17- 













 (b)    To the extent the amount recovered does not
reflect Licensee’s lost profits or royalties (e.g., special or punitive damages), [***] shall be paid to Licensee, and [***] to Caltech. 

8.6    Infringement Defense. If Licensee, its Affiliate or Sublicensee, distributor or
other customer issued by a third party charging infringement of patent rights that cover a Licensed Product, Licensee will promptly notify Caltech. Licensee will be responsible for the expenses of, and will be entitled to control the defense or
settlement of, any such action(s). 
 8.7    Marking. Licensee agrees to mark the Licensed Products
with the numbers of applicable issued patents within the Exclusively Licensed Patent Rights or Improvement Patent Rights, unless such marking is not legally required or commercially infeasible in accordance with normal commercial practices in the
Field, in which case the Parties shall cooperate to devise a commercially reasonable alternative to such marking. 

8.8    Expiration or Abandonment. In a case where one or more patents or particular claims thereof
within the Exclusively Licensed Patent Rights or Improvement Patent Rights expire, or are abandoned, or are declared invalid or unenforceable by a court of last resort or by a lower court from whose decree no appeal is taken, or certiorari is not
granted within the period allowed therefor, then the effect thereof hereunder shall be: 
 (a)    that such patents or
particular claims shall, as of the date of expiration or abandonment or final decision as the case may be, cease to be included within the Exclusively Licensed Patent Rights or Improvement Patent Rights for the purpose of this Agreement; and 

(b)    that such construction so placed upon the Exclusively Licensed Patent Rights or Improvement Patent Rights by the
court shall be followed from and after the date of entry of the decision, and royalties shall thereafter be payable by Licensee only in accordance with such construction. 

8.9    Adjustment. In the event that any of the contingencies provided for in Section 8.8 occurs,
Caltech agrees to renegotiate in good faith with Licensee a reasonable royalty rate under the remaining Exclusively Licensed Patent Rights or Improvement Patent Rights which are unexpired and in effect and under which Licensee desires to retain a
license. 

  
 -18- 













 8.10    Licensee Challenges. If Licensee or any of its
Affiliates brings an action or proceeding, or assists any third party in bringing an action or proceeding, seeking a declaration or ruling that any claim in any of the Exclusively Licensed Patent Rights or Improvement Patent Rights is invalid or
unenforceable, or asserts that any product does not infringe the Exclusively Licensed Patent Rights or Improvement Patent Rights: 

(a)    during the pendency of such action or proceeding, the royalty rate will be increased to double the royalty rate set
forth in Section 5.3; 
 (b)    should the outcome of such action or proceeding determine that any claim of a
Licensed Patent challenged by Licensee is valid, enforceable, and/or infringed by a Licensed Product, the royalty rate will be increased to triple the royalty rate set forth in Section 5.2 and Licensee shall pay Caltech’s attorneys’
fees, expert witness fees, court costs, third-party costs, and other litigation expenses; 
 (c)    Licensee shall have
no right to recoup any royalties paid before such action or proceeding or during the period in which such action or proceeding is pending (including on appeal); 

(d)    Licensee shall not pay royalties into any escrow or other similar account, but rather shall continue to pay
royalties directly to Caltech; and 
 (e)    Caltech shall have full control and authority to defend the Exclusively
Licensed Patent Rights and Improvement Patent Rights in the action or proceeding. 
 Licensee shall provide written notice to Caltech at
least ninety (90) days before Licensee or any of its Affiliates initiates any action or proceeding seeking a declaration or ruling that any claim of any Licensed Patent is invalid or unenforceable or that any product would not infringe (but for
this Agreement) any claim in the Exclusively Licensed Patent Rights or Improvement Patent Rights, Licensee will include with such written notice an identification of all prior art it believes is material. 

Any dispute regarding the validity or enforceability of any of the Exclusively Licensed Patent Rights or Improvement Patent Rights, or whether
any product would infringe (but for this 

  
 -19- 













 
Agreement) any claim in the Exclusively Licensed Patent Rights or Improvement Patent Rights, shall be litigated exclusively in the U.S. District Court for the Central District of California
situated in the County of Los Angeles, and each Party hereby agrees to submit to the exclusive jurisdiction of such court, and waives any objection to venue, for such purposes. 

ARTICLE 9

INCIDENTAL, OR INDIRECT DAMAGES ARISING OUT OF THIS AGREEMENT, HOWEVER CAUSED, UNDER ANY THEORY OF LIABILITY. 
 ARTICLE 10 

TERM AND TERMINATION 

10.1    Term. This Agreement and the rights and licenses hereunder shall take effect on the Effective
Date and continue until the expiration, revocation, invalidation, or unenforceability of the Exclusively Licensed Patent Rights and Improvement Patent Rights licensed to Licensee hereunder, or as long as royalties are due pursuant to Article 5 of
this Agreement, unless earlier terminated pursuant to the terms of this Agreement. Upon expiration of this Agreement under this Section 10.1, Licensee, its Affiliates and Sublicensees shall have a
paid-up, worldwide non-exclusive license under the Technology for use in the Field. 

  
 -21- 













 10.2    Termination for Monetary Breach.
Caltech shall have the right to terminate this Agreement and the rights and licenses hereunder If Licensee fails to make any payment due including patent expenses, minimum annual royalties or royalties hereunder and Licensee continues to fail to
make the payment (either to Caltech directly or by placing any disputed amount into an interest-bearing escrow account to be released when the dispute is resolved) for a period of fourteen (14) days after receiving written notice from Caltech
specifying Licensee’s failure. Upon any such termination, (a) Licensee shall have six (6) months to complete the manufacture of any Licensed Products that are then works in progress for sale and to sell its inventory of Licensed
Products, provided that Licensee pays the applicable royalties, and (b) any sublicenses shall survive termination in accordance with Section 2.3. 

10.3     Termination for Non-Monetary Breach. Non-monetary breach shall include, but is not limited to: (a) failure to fulfill the obligations in Article 7 (Due Diligence), or Section 8.7 (Marking); and (b) pursuit of exploitation of Exclusively
Licensed Patent Rights or Improvement Patent Rights outside the field. Non-monetary breach shall include the cessation of Licensee’s operations in general, or the cessation of Licensee’s commercial
activities in the Field in particular. If this Agreement is materially breached by either party, the non-breaching party may elect to give the breaching party written notice describing the alleged breach. If
the breaching party has not cured such breach within thirty (30) days after receipt of such notice, the notifying party will be entitled, in addition to any other rights it may have under this Agreement, to terminate this Agreement and the
rights and licenses hereunder; such termination shall be deemed to have been effective as of the date of the material breach. 

10.4    Dispute of Breach. Notwithstanding Sections 10.2 and 10.3, if Licensee disputes any alleged
breach in writing within seven (7) days of receiving written notice from Caltech regarding the alleged breach, Caltech shall not have the right to terminate this Agreement unless and until the mediation proceedings as described in Article 12
have concluded, and (a) if the mediation results in the parties settling such dispute, Caltech may terminate this Agreement in accordance with the terms of the settlement if Licensee fails to comply with the terms of such settlement, or
(b) if the mediation fails to settle such dispute, Caltech may terminate this Agreement if Licensee fails to cure such breach within thirty (30) days after the conclusion of the mediation proceedings. If the parties agree pursuant to
Article 12, whether prior to or following 

  
 -22- 













 
the conclusion of the mediation proceedings, to settle such dispute by arbitration, Caltech shall not have the right to terminate this Agreement unless and until an arbitrator determines in a
written decision delivered to the parties that such breach occurred, and Licensee fails to cure such breach within thirty (30) days after such determination. 

10.5    Bankruptcy or Insolvency. This Agreement shall terminate, without notice, (a) upon
Licensee’s filing for bankruptcy, receivership, or bankruptcy proceedings or any other proceedings for the settlement of Licensee’s debts; (b) upon Licensee making an assignment for the benefit of creditors; or (c) upon
Licensee’s dissolution or ceasing to do business. Caltech may terminate this Agreement upon the insolvency of the Licensee. Licensee must inform Caltech of its intention to file a voluntary petition of bankruptcy, or of another’s intention
to file an involuntary petition of bankruptcy, at least thirty (30) days prior to the filing of such a petition. Licensee’s filing without conforming to this requirement shall be deemed a material,
pre-petition incurable breach of this Agreement which will cause this Agreement to terminate without notice upon such filing. 

10.6    Accrued Liabilities. Termination of this Agreement for any reason shall not release any party
hereto from any liability which, at the time of such termination, has already accrued to the other party or which is attributable to a period prior to such termination, nor preclude either party from pursuing any rights and remedies it may have
hereunder or at law or in equity which accrued or are based upon any event occurring prior to such termination. 

10.7    Survival. The following shall survive any expiration or termination (in whole or in part) of
this Agreement: (a) any provision plainly indicating that it should survive; (b) any royalty due and payable on account of activity prior to the termination; and (c) Sections or Articles 5.10, 9, 11,12,13, and 14.7.

Agreement to any third party without the prior written consent of the other party, except to prospective investors, sublicensees and acquirers, and to such party’s accountants, attorneys and other professional advisors, or as required by
securities or other applicable laws. Except 

  
 -23- 













 
with respect to the above third parties, each party agrees not to disclose the subject matter of the Exclusively Licensed Patent Rights or Improvement Patent Rights to any third party unless
under an appropriate nondisclosure agreement (“NDA”) that is mutually agreed upon by Caltech and Licensee. 

11.2    Permitted Disclosures. Notwithstanding the foregoing, each party may disclose:
(a) confidential information as required by securities or other applicable laws or pursuant to governmental proceedings, provided that the disclosing party gives advance written notice to the other party and reasonably cooperates therewith in
limiting the disclosure to only those third parties having a need to know; and (b) the fact that Licensee has been granted a license under the Exclusively Licensed Patent Rights and Improvement Patent Rights. 

ARTICLE 12 
 DISPUTE
RESOLUTION 
 12.1    No issue of the validity of any of the licensed patents, enforceability of any of the licensed
patents, infringement of any of the licensed patents, the scope of any of the claims of the licensed patents and/or any dispute that includes any such issue, shall be subject to mediation under this Agreement unless otherwise agreed by the Parties
in writing. In addition, no dispute between the Parties as to any matter relating to this Agreement shall be subject to arbitration unless otherwise agreed by the Parties in writing. 

12.2    Except for those issues and/or disputes described in Section 10.2, any dispute between the Parties concerning
the interpretation, construction or application of any terms, covenants or conditions of this Agreement shall be resolved by mediation. 

12.3    Mediation shall be in the Los Angeles office of ADR Services, Inc. (http://www.adrservices.org/) before an
attorney or a retired judge with experience in intellectual property or patent matters, and contract, commercial or business disputes selected by the Parties from candidates proposed by ADR Services, Inc. in accordance with the ADR Mediation Rules
and Procedures in force at the time the mediation is initiated. 
 12.4    The requirement for mediation shall not be
deemed a waiver of any right of termination under this Agreement, subject to the provisions of Section 10.4. 

  
 -24- 













 12.5    Each party shall bear its own expenses incurred in connection
with any attempt to resolve disputes hereunder, but the compensation and expenses of the mediator shall be borne equally. 
 ARTICLE 13

 PRODUCT LIABILITY 

13.1    Indemnification. Licensee agrees that Caltech (including its trustees, officers, faculty and
employees) shall have no liability to Licensee, its Affiliates, their customers or any third party for any claims, demands, losses, costs, or other damages which may result from personal injury, death, or property damage related to the Licensed
Products (“Product Liability Claims”). Licensee agrees to defend, indemnify, and hold harmless Caltech, its trustees, officers, faculty and employees from any such Product Liability Claims, provided that: (a) Licensee is
notified promptly of any Product Liability Claims; (b) Licensee has the sole right to control and defend or settle any litigation within the scope of this indemnity; and (c) all indemnified parties cooperate to the extent necessary in the
defense of any Claims. 
 13.2    Insurance. Prior to such time as Licensee begins to manufacture,
sell, license, distribute or use Licensed Products, Licensee shall at its sole expense procure and maintain policies of comprehensive general liability insurance in amounts not less than one million dollars ($1,000,000.00) per incident and three
million dollars ($3,000,000.00) in annual aggregate, and naming those indemnified under Section 13.1 as additional insureds. Such comprehensive general liability insurance shall provide: (a) product liability coverage and (b) broad
form contractual liability coverage for Licensee’s indemnification of Caltech under Section 13.1. In the event the aforesaid product liability coverage does not provide for occurrence liability, Licensee shall maintain such comprehensive
general liability insurance for a reasonable period of not less than five (5) years after it has ceased commercial distribution or use of any Licensed Product. Licensee shall provide Caltech with written evidence of such insurance upon request
of Caltech. 
 13.3    Loss of Coverage. Licensee shall provide Caltech with notice at least
fifteen (15) days prior to any cancellation, non-renewal or material change in such insurance, to the extent Licensee receives advance notice of such matters from its insurer. If Licensee docs not obtain


  
 -25- 













 replacement insurance providing comparable coverage within sixty (60) days following the date of such
cancellation, non-renewal or material change, Caltech shall have the right to terminate this Agreement effective at the end of such sixty (60) day period without any additional waiting period; provided
that if Licensee provides credible written evidence that it has used reasonable efforts, but is unable, to obtain the required insurance, Caltech shall not have the right to terminate this Agreement, and Caltech instead shall cooperate with Licensee
to either (at Caltech’s discretion) grant a limited waiver of Licensee’s obligations under this Article or assist Licensee in identifying a carrier to provide such insurance or in developing a program for self-insurance or other
alternative measures.

14.7    Governing Law. This Agreement, the legal relations between the Parties and any action,

California. 
 14.8    No Endorsement. Licensee agrees that it shall not make any form of
representation or statement which would constitute an express or implied endorsement by Caltech or the Jet Propulsion Laboratory (JPL) of any Licensed Product, and that it shall not authorize others to do so, without first having obtained written
approval from Caltech, except as may be required by governmental law, rule or regulation. 
 14.9    Export

cause to be exported, re-exported, resold, shipped, or diverted, directly or indirectly, any product or technical data or software of the other party, or the direct product of such technical data or software,
to any country for which the United States Government or any agency thereof requires an export license or other governmental approval without first obtaining such license or approval. 

14.10    Force Majeure. Neither party shall lose any rights hereunder or be liable to the other party for
damages or losses (except for payment obligations) on account of failure of performance by the defaulting party if the failure is occasioned by war, strike, fire, Act of God, earthquake, flood, lockout, embargo, governmental acts or orders or
restrictions, failure of suppliers, or any other reason where failure to perform is beyond the reasonable control and not caused by the negligence or intentional conduct or misconduct of the nonperforming party, and such party has exerted all
reasonable efforts to avoid or remedy such force majeure; provided, however, that in no event shall a party be required to settle any labor dispute or disturbance.
