          progress report describing progress on research and development, regulatory approvals, manufacturing, marketing and sales during the preceding twelve (12) month period and plans for the forthcoming year (“Progress Reports”).  Company shall also
          provide any reasonable additional data SBP requires to evaluate Company’s performance.  Company shall additionally provide a copy of the operating agreement for Company (“Operating Agreement”) and any updates thereto promptly and upon written
          request by SBP.  All such Progress Reports, additional data and the Operating Agreement shall be Company’s Confidential Information and held by SBP in confidence in accordance with Article 16.

      

      

      3.4.3          If Company at any time defaults in providing the written research and development plan or Progress Report or Operating Agreement when due hereunder and/or fails to provide the
        written research and development plan or Progress Report within sixty (60) days after Company’s receipt of written request therefor from SBP or if the terms of the Operating Agreement violate SBP’s obligations or status as a non-profit, tax-exempt
        research institution, SBP may, at its option, terminate this Agreement and all licenses granted herein upon written notice to Company.

      4.          PAYMENTS AND REPORTS

      

      

      4.1          License Fee.  As partial consideration for the rights conveyed by SBP under this Agreement,
          Company shall, within thirty (30) days after the Effective Date of this Agreement, pay to SBP, by way of equity transfer, a one-time, non-creditable, non-refundable license fee in the form of twenty percent (20%) of the common equity of the
          Company.  Within such thirty (30) days after the Effective Date of this Agreement, Company shall provide SBP with a copy of the Operating Agreement confirming SBP’s rights under this section.

      

      

      4.2          Royalties.  In addition to the consideration described in Section 4.1, Company shall pay SBP a
          royalty of four percent (4%) of Net Sales of Identified Products by Company and its Affiliates and Identified Product Licensee on an Identified Product-by-Identified Product, country-by-country basis during
          the term of this Agreement.  If a royalty must be paid to a third party by Company or its Affiliates or Identified Product Licensee based upon patents or other intellectual property rights in connection with
          an Identified Product, then the royalty payable to SBP pursuant to this Section 4.2 shall be reduced by fifty percent (50%) of the applicable third party royalty; provided that, in no instance shall the royalty payable to SBP by Company or its
          Affiliates ever be reduced to less than two percent (2%) of Net Sales of Identified Products.

      

      

      4.3          Sublicensing Revenue.  Company shall also pay to SBP twenty-five percent (25%) of any Sublicensing Revenue.

      

      

      4.4          Combination Products.  If Company or its Affiliates or Identified Product Licensee sell an Identified Product that includes components other than those covered by the Licensed Patents that contribute significant and material value to said Identified Product (“Combination Identified Product”), then in
          lieu of the royalty rate specified in Section 4.2, inclusive of any reductions for third party royalties, the applicable royalty rate on the Net Sales of such Combination Identified Product shall be calculated as the product obtained by
          multiplying the royalty rate specified in Section 4.2 by the fraction A/(A+B), in which A is the value of the technology licensed under this Agreement and B is the value of the other components; provided, however, that in no event shall the
          royalty rate payable to SBP for Net Sales of Combination Identified Products ever be reduced to less than [add percent royalty in words and numbers] of Net Sales of the Combination Identified Product. For purposes of this Section 4.3 the “value”
          of each component contributing value to the Identified Product shall mean that component’s contribution to the combined value of the Combination Identified Product. Furthermore, carriers, diluents, solvents and other such constituents of a
          potential Identified Product shall be deemed not to contribute significant and material value to said Identified Product.

      

      

      4.5          License Maintenance Fee.  Company agrees to pay to SBP an annual License Maintenance Fee according
          to the following schedule:

      

      

      (a)          Five Thousand U.S. Dollars ($5,000) per year beginning on the first anniversary of the Effective Date and continuing
          annually for each subsequent year until the fourth anniversary of the Effective Date; and

      

      

      (b)          Ten Thousand U.S. Dollars ($10,000) per year beginning on the fourth anniversary of the Effective Date and continuing
          annually for each subsequent year until the seventh anniversary of the Effective Date; and

      

      

      (c)          Twenty Thousand U.S. Dollars ($20,000) per year beginning on the seventh anniversary of the Effective Date and
          continuing annually for each subsequent year thereafter for the duration of this Agreement.

      

      

      The License Maintenance Fee shall be payable within thirty (30) days of each such anniversary.  The License Maintenance Fee is non-refundable and is not an advance or credit against royalties or any
        other payments.  Following the First Commercial Sale of a royalty-bearing Identified Product made by Company, its Affiliates or an Identified Product Licensee, the License Maintenance Fee shall be creditable on an annual basis against earned
        royalties actually paid by Company to SBP.

      

      

      
        8

        
          


      

      

      

      4.6          Milestone Payments.  For each Identified Product, within thirty (30) days after the occurrence of
          each Milestone Event set forth below, Company shall also pay to SBP the following milestone payments:

      

      

      (i)          No payment is due under this section upon the filing of the first IND for such Identified Product with the FDA or its foreign equivalent;

      

      

      (ii)          One Hundred Thousand U.S. Dollars ($100,000) is due upon the initiation of the first Phase II clinical trial for
          such Identified Product;

      

      

      (iii)          One Million U.S. Dollars ($1,000,000) is due upon the initiation of the first Phase III clinical trial for such
          Identified Product;

      

      

      (iv)          Two Million U.S. Dollars ($2,000,000) is due upon the filing of NDA or foreign equivalent in a major market

      

      

      (v)          Five Million U.S. Dollars ($5,000,000) is due upon final approval of the first NDA for each indication by the United
          States FDA or its foreign equivalent in a Major Market.

      

      

      4.7          Payments.  Payment of the royalties specified in Section 4.2 and Section 4.3 shall be made by
          Company to SBP within thirty (30) days after March 31, June 30, September 30 and December 31 of each year during the term of this Agreement covering the quantity of Identified Products sold by Company and/or its Affiliates or Identified
        Product Licensee, as appropriate, during the preceding calendar quarter.  After termination or expiration of this Agreement, a final payment shall be made by Company covering the whole or partial calendar quarter.
          Commencing with the First Commercial Sale, each quarterly payment shall be accompanied by a written statement of Net Sales of Identified Products by Company and/or its Affiliates or Identified Product Licensee,
          as appropriate, during such calendar quarter.  Such written statements shall be duly signed by the Comptroller of Company on behalf of Company and shall show the Net Sales of Identified Products by Company and/or its Affiliates or
        Identified Product Licensee, as appropriate, during such calendar quarter and the amount of royalties payable under this Agreement based thereon.

      

      

      4.8          Failure to Make Payments.  In the event Company fails to make any payment due and payable to SBP
          hereunder, including but not limited to the annual License Maintenance Fee, Royalties, Milestone Payments and/or Patent Costs, SBP may, at its sole option, terminate this Agreement, in accordance with the procedures and cure provisions of Section
          11 (Term and Termination).

      

      

      4.9          Form of Payment.  All payments due hereunder are expressed in and shall be paid by wire transfer
          or check payable in United States Dollars, without deduction of exchange, collection or other charges, to SBP, or to the account of SBP at such other bank as SBP may from time to time designate by written notice to Company.

      

      

      4.10          Interest.  In the event that any payment due hereunder is not made when due, the payment shall
          accrue interest beginning on the tenth day following the due date thereof, calculated at the annual rate of the sum of (i) two percent (2%) plus (ii) the prime interest rate quoted by The Wall Street Journal on the date said payment is due, the
          interest being compounded on the last day of each calendar quarter; provided, however, that in no event shall said annual interest rate exceed the maximum legal interest rate for corporations.  Each such royalty payment when made shall be
          accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of SBP to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any
          payment.

      

      

      
        9

        
          


      

      

      

      4.11          Exchange Rate.  With respect to each quarter, for countries other than the United States,
          whenever conversion of payments from any foreign currency is required, and such conversion shall be made at the rate of exchange reported in The Wall Street Journal on the last business day of the applicable calendar quarter.

      

      

      4.12          Taxes.

      

      

      4.12.1          The payments required to be paid by Company to SBP pursuant to this agreement may be paid with deduction for taxes withheld under another country’s domestic law, if applicable.  The
        Company will reasonably assist SBP to obtain full benefit of any applicable tax treaty to reduce the amount of such withheld taxes.

      

      

      4.12.2          In the event that the Company sublicenses the Licensed Technology to a third party that qualifies as a Untied States taxpayer, then all royalties payable to SBP on Net Sales of
        Licensed Product shall be paid directly to SBP by sublicensee, to avoid payment of withholding taxes imposed by Company’s country.

      

      

      4.12.3          In the event that the Company sublicenses the Licensed Technology to a third party that does not qualify as a Untied States taxpayer, then Company will ensure that the terms of the
        sublicense agreement are such that the royalties payable to SBP on Net Sales of Licensed Product will not be reduced by the amount of any withholding tax imposed by Identified Product Licensee on Company’s royalty payment.

      

      

      5.          RECORDS AND INSPECTION

      

      

      Company shall maintain or cause to be maintained a true and correct set of records pertaining to the Net Sales of Identified Products by Company and/or its Affiliates
        or Identified Product Licensee under this Agreement.  Such records shall be kept at Company’s principal place of business or the appropriate principal place of business of the appropriate Affiliate or
        Identified Product Licensee to which this Agreement relates.  During the term of this Agreement and for a period of three (3) years thereafter, Company agrees to permit an independent certified public accountant or
          other independent agent selected and paid by SBP, and reasonably acceptable to Company, to have access during ordinary business hours to such records as are maintained by Company, or its Affiliates or Identified Product Licensee, as may be
        necessary, in the opinion of such party, to determine the correctness of any report and/or payment made under this Agreement. Such party shall not report to SBP any information other than as to the correctness of any such report or payment. Such
        audits may be exercised no more than once in any twelve (12) month period upon at least thirty (30) days prior written notice to Company.  Any and all information learned or acquired by SBP’s agent or accountant pursuant to any such inspection
        shall be treated the same as Confidential Information of Company, in accordance with the provisions of Section 16 below.  Before undertaking any such inspection, SBP’s agent or accountant shall agree in writing to be bound by the terms of this
        Section 5 and Section 16. SBP shall bear the full cost of such audit unless the audit reveals an underpayment of royalty by more than five percent (5%).  The cost of the audit shall be paid by Company if the discrepancy is an underpayment of
        royalty by more than five percent (5%); if the discrepancy is an overpayment, SBP shall refund to Company the amount of such overpayment within fifteen (15) days after the audit.  Company shall pay SBP all amounts SBP is entitled to as determined
        by the audit, plus a one-and-a-half percent (1.5%) late fee on the amount due to SBP, compounded monthly for each month that the payment is late from the date originally due.

      

      

      6.          PATENTS

      

      

      6.1          Patent Prosecution and Maintenance. During the term of this Agreement and provided Company
          continues to timely pay Ongoing Patent Costs (defined below) in accordance with section 6.2, below, SBP shall diligently prosecute and maintain Licensed Patents using counsel to be chosen by SBP and to which Company has no reasonable objection.
          For so long as Company continues to timely pay Ongoing Patent Costs in accordance with section 6.2, below, Company shall be provided with copies of all documents relating to the filing, prosecution, and maintenance of Licensed Patents in
          sufficient time to review such documents and comment thereon, if desired by Company, prior to filing, provided, however, that if Company has not commented on such documents prior to the deadline for filing a response with the relevant government
          patent office, SBP shall be free to respond without consideration of Company’s comments.  Company shall keep this documentation confidential in accordance with Section 16 (Confidentiality) herein.

      

      

      
        10

        
          


      

      

      

      6.2          Patent Costs.  Company shall reimburse SBP the sum of  Six Hundred, Forty-Six Thousand, Four
          Hundred Sixteen U.S. Dollars (646,416 USD), within five (5) years after the Effective Date, for all patent expenses incurred incident to the filing, prosecution and maintenance of the Licensed Patents incurred and paid by SBP prior to the
          Effective Date (“Historical Patent Costs”).  In the event, Company has raised at least an aggregate of Five Million U.S. Dollars ($5,000,000) in gross proceeds in one or more equity financings or has made its First Commercial Sale prior to the
          fifth anniversary of the Effective Date, then Five Hundred Thousand U.S. Dollars ($500,000) of Historical Patent Costs shall be immediately due and payable within thirty days of such event and in the event that Company has raised at least an
          aggregate of Ten Million U.S. Dollars ($10,000,000), then all Historical Patent Costs not yet paid by Company shall be immediately due and payable within thirty days of such event.  Company shall reimburse SBP, within forty-five (45) days after
          Company receives an itemized invoice therefor, for all undisputed patent expenses incurred incident to the filing, prosecution and maintenance of the Licensed Patents in specific territories mutually agreed upon by the Parties in writing, which
          territories shall encompass such countries or jurisdictions as Company shall reasonably request, but which shall not encompass less than the United States, and incurred and paid by SBP either: (i) prior to the Effective Date and not previously
          invoiced to Company, or (ii) after the Effective Date (“Ongoing Patent Costs”).  In the event that SBP licenses the Licensed Patents to any third parties, Company’s share of Ongoing Patent Costs shall thereafter be reduced proportionally.

      

      

      6.3          Effect of Company’s Discontinuing Payments.  In the event that Company decides not to continue to support the prosecution of any patent or
        patent application in the United States or in the territories agreed in writing in Section 6.2, or the maintenance of a patent within the Licensed Patents, Company will give SBP at least sixty (60) days prior written notice of such election, except
        in the case in which the decision not to support continued prosecution is in response to a communication from SBP, SBP’s patent attorney, a patent office, or a foreign associate, relating to a deadline for taking action, in which case Company’s
        notice will be timely if given within half the time remaining between receipt by Company of the communication and the deadline for taking action.  No such notice will have any effect on Company’s obligations to pay expenses incurred up to the
        effective date of such election. From and after the effective date of such election, SBP will have the right, but not the obligation, to pay for the prosecution and/or maintenance of the patent application or patent which Company is discontinuing
        and Company shall have no further rights thereto.  Company may freely discontinue payment of expenses for cause (i.e., official actions, prior art, legal decisions, or statutes or other expressions of local law, which reasonably indicate that the
        material claims in the application or patent are or are likely to be unpatentable, unenforceable, or invalid).  Where discontinuance of payments is not for cause (i.e., Company is unwilling to support and reimburse SBP for all reasonable and
        necessary patent expense related to the filing, prosecution and maintenance of the Licensed Patents, which are likely to be patentable, enforceable, or valid), from and after the effective date of such election, any such patent application or
        patent in any country as to which Company have elected to discontinue payment shall have the effect of excluding all patent applications or patents directed to the same subject matter in all relevant countries thereof from Licensed Patents, and
        from the scope of the license granted under this Agreement. All rights relating to such patent applications or patents shall revert to SBP and may be freely licensed by SBP to any other person or entity.

      

      

      6.4          Cooperation.  SBP and Company shall cooperate fully in the preparation, filing, prosecution and
          maintenance of Licensed Patents and of all patents and patent applications licensed to Company. Each Party shall provide to the other timely notice as to all matters which come to its attention and which may affect the preparation, filing,
          prosecution or maintenance of any such patent applications or patents.

      

      

      6.5          Patent Marking.  Company shall mark all Identified Products made, used or sold under the terms of
          this Agreement, or their containers, in accordance with the applicable patent marking laws.

      

      

      7.          INDEMNITY AND INSURANCE

      

      

      7.1          Indemnity.  Company hereby agrees to indemnify and hold harmless SBP and its directors, officers,
          researchers, scientists, employees and agents (collectively, the “SBP Indemnitees”) from and against any losses, claims, damages, costs, and expenses (including attorneys’ fees) (collectively, “Losses”) incurred in connection with or arising from
          (i) any third party claims arising from Company’s use of any Licensed Technology; and (ii) any claims for death, personal injury or related property damage arising from Company’s development, manufacture, sale, marketing, distribution or use of any Identified Products, but excluding Losses arising from or relating to the breach of this Agreement by SBP or the gross negligence or willful misconduct of any SBP
          Indemnitees.  Without limiting the generality of the foregoing, such indemnity obligation shall apply to any product liability or other claims, including without limitation, personal injury, death or property damage, made by employees,
          subcontractors, or agents of Company, as well as by any customer, patient, hospital, doctor, or member of the general public who buys or uses an Identified Product.  Company shall monitor customer complaints and shall be responsible for
          corrections, withdrawal or alert notices.

      

      

      
        11

        
          


      

      

      

      7.2          Insurance.  Company shall for so long as Company manufactures, uses or sells any Identified
          Product, maintain in full force and effect policies of (i) worker’s compensation and/or employers’ liability insurance within statutory limits and (ii) general liability insurance (with broad form general liability endorsement) with limits of not
          less than one million dollars ($1,000,000) per occurrence and a ten million dollar ($10,000,000) annual aggregate.  From and after the time that Company or any of its Affiliates begin human clinical trials on any Identified Product, Company shall
          use reasonable commercial efforts to obtain and maintain comprehensive general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers in an amount which is customarily carried by
          companies at a comparable stage of development of new pharmaceutical products.  Such coverage(s) shall be purchased from a carrier or carriers deemed reasonably acceptable to SBP and shall name SBP as additional insureds.  Upon request by SBP,
          Company shall provide to SBP copies of said policies of insurance.

      10.          LIMITATION OF LIABILITY

      

      

      NEITHER PARTY SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT OR ANY
        LICENSE GRANTED HEREUNDER.

      

      

      11.          TERM AND TERMINATION

      

      

      11.1          Term.  The rights and licenses granted to Company and its Affiliates
        pursuant to Section 2.1 hereof, and the obligation to pay royalties on the Net Sales of Identified Products pursuant to Sections 4.2 and 4.3, shall continue in full force and effect, on an Identified
          Product-by-Identified Product and country-by-country basis, until the later of (a) the final abandonment of all pending patent applications within the Licensed Patents or (b) the expiration of the last to expire patent within the Licensed
        Patents containing a Valid Claim covering such product in the country of sale, whereupon Company shall have the royalty-free right to practice the Licensed Technology.

      

      

      This Agreement shall become effective on the Effective Date and shall continue in full force and effect until the expiration of Company’s rights and licenses under Section 2.1 hereof, as set forth
        in Section 11.1, unless earlier terminated pursuant to this Article 11.

      

      

      11.2          Termination by Notice.  Notwithstanding any provision herein, Company may terminate this Agreement in its entirety, at any time by giving SBP
        at least sixty (60) days’ prior written notice.  All rights and obligations of Company with respect to such patent(s) and patent application(s) shall terminate.

      

      

      11.3          Default Remedies.

      

      

      11.3.1          If Company at any time defaults in the payment of any sum when due hereunder and fails to make such payment within thirty (30) days after receipt of written notice thereof by SBP,
        SBP may, at its option, terminate this Agreement and all licenses granted herein upon written notice.

      

      

      11.3.2          If either party at any time defaults in the making of any report hereunder, or commits any material breach of any of the terms, covenant or provisions of this Agreement, including
        but not limited to failing to achieve a Milestone as in Section 3.3, failure to make any payment due hereunder, or makes any false report and fails to remedy any such default, material breach or report within sixty (60) days after receipt of
        written notice thereof by the non-breaching party, the non-breaching party may, at its option, terminate this Agreement and all licenses granted herein upon written notice.

      

      

      11.4          Default for Bankruptcy.  Each Party shall have the right, at its option, to terminate this
          Agreement in the event that the other Party shall;

      

      

      (i)          file in court or agency pursuant to any applicable state or federal petition in bankruptcy (other than dissolution or
          winding up for the purposes of reconstruction or amalgamation) or if such party is served with an involuntary petition in bankruptcy, or

      

      

      (ii)          make an assignment of all or substantially all of its assets for the benefit of creditors, or

      

      

      (iii)          in the event that a receiver or trustee is appointed for the other Party and such Party shall, after the expiration
          of thirty (30) days following any of the events enumerated above, be unable to secure a dismissal, stay or other suspension of such proceedings.  In the event of termination of this Agreement all rights to the Licensed Patents shall revert to

      11.5          Rights after Termination.  At the date of any termination of this Agreement by Company pursuant
          to Section 11.2 hereof or by SBP pursuant to Section 11.3 hereof for material breach by Company or Section 11.4 hereof in the event of bankruptcy insolvency, dissolution, or receivership proceedings by Company, as of the date of termination set
          forth in Company’s termination notice (in the case of termination under Section 11.2) or receipt by Company of notice of such termination (in the case of a termination under Section 11.3 or 11.4), Company and its Affiliates shall immediately
          cease exploiting any of the Licensed Patents and return all copies of the same to SBP and cease production of all Identified Products; provided, however, that Company, its Affiliates and each Identified Product Licensee may dispose of any
          Identified Products manufactured as of the date of termination, and may complete manufacture of Identified Products then in the process of manufacture, and sell them, provided that Company shall pay to SBP running royalties in accordance with
          Sections 4.2 and 4.3 with respect thereto and otherwise complies with the terms of this Agreement.

      

      

      If SBP terminates this Agreement pursuant to this section for material breach by Company, then all rights and obligations of Company with respect to such patent(s) and patent application(s) shall terminate.  Upon such
        termination Company must, and hereby agrees to, transfer to SBP all information and records required for SBP to move the technology forward.  Such information and records includes any regulatory filings, material, and all known information about
        the Licensed Product, including how it is manufactured; as well as any information describing the clinical research plan for the product and the specific protocol for human clinical trials.

      

      

      11.6          No Waiver; Survival.  No termination of this Agreement shall constitute a termination or a waiver
          of any rights of either Party against the other Party accruing at or prior to the time of such termination.  The obligations and rights of the Parties under Sections 1, 2.5, 7.1, 7.2, 9, 10, 11, 14, 15, 16, 17 and the confidentiality-related
          provisions of Sections 3.4.1 and 3.4.2 shall survive termination of this Agreement.

      

      

      12.          ASSIGNABILITY

      

      

      Company shall not assign the license granted hereunder or this Agreement without the prior written consent of SBP, which consent shall not be unreasonably withheld; provided,
        however, that Company, without such consent, may assign all of its rights and obligations hereunder to an Affiliate or to the acquiring party in connection with the transfer of all or substantially all of its business and assets to which this
        Agreement relates to an acquiring party or in the event of its merger or consolidation with that acquiring party, if and only if the assignee shall assume all obligations of Company under this Agreement.  Any attempted assignment in violation of
        this Section 12 shall be null and void.

      

      

      13.          GOVERNMENTAL COMPLIANCE

      

      

      13.1          Compliance with Laws.  Company shall at all times during the term of this Agreement and for so
          long as it sells imports, exports, manufactures, uses, develops, distributes, markets or otherwise commercially exploits Identified Products and/or Licensed Technology comply and require its Affiliates and Identified Product Licensees to comply
          with all laws that control the import, export, manufacture, use, development, sale, marketing, distribution and other commercial exploitation of Identified Products and/or Licensed Technology or any other activity undertaken pursuant to this
          Agreement.

      

      

      13.2          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, Company shall assume all legal obligations to do so.  Company shall notify SBP if it becomes aware that this Agreement is subject to a United
          States or foreign government reporting or approval requirement.  Company 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.

      16.          CONFIDENTIALITY

      

      

      16.1          Treatment of Confidential Information.  During the term of this Agreement, and for a period of
          five (5) years after this Agreement expires or terminates, a Party receiving Confidential Information of the other Party shall (a) maintain in confidence such Confidential Information to the same extent such receiving Party maintains its own
          proprietary information (but at a minimum each Party shall use reasonable efforts); (b) not disclose such Confidential Information to any third party without prior written consent of the other Party to this Agreement; and (c) not use such
          Confidential Information for any purpose except those permitted by this Agreement.  A Party shall have no such obligation with respect to any portion of such Confidential Information which:

      

      

      (i)          is publicly disclosed by the disclosing Party, or is otherwise publicly disclosed without the fault of the receiving
          Party, either before or after it becomes known to the receiving Party; or

      

      

      (ii)          was known to the receiving Party prior to when it was received from the disclosing Party, as evidenced by
          contemporaneous written records; or

      

      

      (iii)          is subsequently disclosed to the receiving Party in good faith by a third party who has a right to make such a
          disclosure; or

      

      

      (iv)          has been published by a third party which had a right to do so; or

      

      

      (v)          has been independently developed by the receiving Party without the aid, application or use of Confidential
          Information from the disclosing Party, such independent development being performed solely by persons not having access whatsoever to the disclosing Party’s Confidential Information, as evidenced by contemporaneous written evidence of same; or

      

      

      (vi)          is required by law to be disclosed, but then only to the limited extent of such legally required disclosure;
          provided, however, that the other Party shall be given prompt notice of any such legally required disclosure.

      

      

      Notwithstanding the foregoing, Company may disclose SBP’s Confidential Information to the extent that such disclosure is reasonably necessary, in accordance with the term and
        conditions of this Agreement, (a) to file or prosecute patent applications within the Licensed Patents, (b) pursue or defend litigation relating to the Licensed Patents, (c) seek or maintain regulatory approval for Identified Products, or (d) for
        compliance with applicable governmental regulations; provided that, if Company intends to make any such disclosure, it shall give reasonable advance written notice to SBP of such intention.  Furthermore, nothing in this Section 16.1 shall be
        construed to preclude Company from disclosing SBP’s Confidential Information to third parties in connection with the development and commercialization of Identified Products including, without limitation, co-development, co-marketing and
        co-promotion in connection therewith, or in the process of obtaining private or public financing, as long as such third party(ies) agrees in writing to be bound by confidentiality provisions no less strict than those set forth in this Section 16.1.

      

      

      16.2          Publicity.  Any publication, news release or other public announcement relating to this
          Agreement, including without limitation, entering to into this Agreement, or to the performance hereunder, shall first be reviewed and approved by both Parties, which approval shall not be unreasonably withheld. Either Party shall be entitled to
          disclose the substance of this Agreement to its shareholders (and to prospective shareholders to whom its stock is offered for purchase) under a confidentiality agreement consistent with this Agreement.  Each Party shall also be entitled to
          provide a copy of this Agreement to the Securities and Exchange Commission (if required).

      17.          GENERAL PROVISIONS

      

      

      17.1          Use of the Names.  Company agrees that it shall not use in any way the name “Sanford Burnham
          Prebys Medical Discovery Institute” or any logotypes or symbols associated with SBP or the names of any of the scientists or other researchers at SBP without the prior written consent of SBP. SBP agrees that it shall not use the name DrugCendR or
          any logotypes or symbols associated therewith or the names of any scientists or other researchers of any of the foregoing, without the prior written consent of Company.

      

      

      17.2          Independent Contractors.  The Parties hereby acknowledge and agree that each is an independent
          contractor and that neither Party shall be considered to be the agent, representative, master or servant of the other Party for any purpose whatsoever, and that neither Party has any authority to enter into a contract, to assume any obligation or
          to give warranties or representations on behalf of the other Party without the prior written consent of the other Party.  Nothing in this relationship shall be construed to create a joint venture, agency, partnership, fiduciary or other similar
          relationship between the Parties.

      

      

      17.3          Non-Waiver.  The Parties covenant and agree that if a Party fails or neglects for any reason to
          take advantage of any of the terms provided for the termination of this Agreement or if a Party, having the right to declare this Agreement terminated, shall fail to do so, any such failure or neglect by such Party shall not be a waiver or be
          deemed or be construed to be a waiver of any cause for the termination of this Agreement subsequently arising, or as a waiver of any of the terms, covenants or conditions of this Agreement or of the performance thereof.  None of the terms,
          covenants and conditions of this Agreement may be waived by a Party except by its written consent.

      

      

      17.4          Reformation.  Any provision of this Agreement which is prohibited or unenforceable in any
          jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability shall not invalidate or render
          unenforceable such provision in any other jurisdiction.  Should any provision of this Agreement be so held to be unenforceable, such provision, if permitted by law, shall be considered to have been superseded by a legally permissible and
          enforceable clause which corresponds most closely to the intent of the Parties as evidenced by the provision held to be unenforceable.

      

      

      17.5          Modification.  No amendment or modification of this Agreement shall be effective unless in
          writing signed by the Parties hereto  No provision of this Agreement shall be varied, contradicted or explained by any oral agreement, course of dealing or performance or any other matter not set forth in an agreement in writing and signed by the
          Parties.

      

      

      17.6          Force Majeure.  No liability hereunder shall result to a Party by reason of delay in performance
          to the extent caused by circumstances beyond the reasonable control of the Party, including, without limitation, acts of God, fire, flood, war, civil unrest, labor unrest, or terrorism.

      

      

      17.7          Entire Agreement.  The terms and conditions herein constitute the entire agreement between the
          Parties and shall supersede all previous agreements, either oral or written, between the Parties hereto with respect to the subject matter hereof.  No agreement or understanding bearing on this Agreement shall be binding upon either Party hereto
          unless it is in writing and signed by the duly authorized officer or representative of each of the Parties and it expressly refers to this Agreement.

      

      

      17.8          Headings.  The headings for each Section in this Agreement have been inserted for convenience of
          reference only and are not intended to limit or expand on the meaning of the language contained in the particular Section.

      

      

      
        17

        
          


      

      

      

      17.9          Counterparts.  This Agreement may be signed in two counterparts, each of which shall be deemed an
          original, but both of which together shall constitute one and the same instrument.  Signatures may be transmitted by facsimile, thereby constituting the valid signature and delivery of this Agreement.

      

      

      17.10          No Strict Construction.  This Agreement has been prepared jointly and shall not be strictly
          construed against either Party.

      

      

      17.11          No Third Party Beneficiaries.  No person or entity other than SBP, Company and their respective
          Affiliates and permitted assignees hereunder shall be deemed an intended beneficiary hereunder or have any right to enforce any obligation of this Agreement.

      

      

      17.12          Dispute Resolution.  The Parties shall make diligent and reasonable efforts to amicably settle
          all disputes, controversies, or differences which may arise between the Parties hereto, out of, or in relation to or in connection with this Agreement.  If a Party shall reasonably determine that it must seek a preliminary injunction, temporary
          restraining order or other provisional relief, upon the occurrence of a dispute between the Parties, including, without limitation, any breach of this Agreement or any obligation relating thereto, the matter shall be referred first to the
          President of Company and the CEO of SBP, or their designees, who shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner if circumstances permit, recognizing that an aggrieved party that wishes to seek a
          preliminary injunction or temporary restraining order may need to resort immediately to legal recourse.  If such efforts do not result in a mutually satisfactory resolution, the dispute shall be finally settled by arbitration, by which each Party
          hereto is bound.  Such arbitration shall be held in San Diego, California in accordance with the rules of the American Arbitration Association.  Any such arbitration shall be conducted in the English language.  There shall be three (3)
          arbitrators, including one nominee of Company, one nominee of SBP, and a third person selected by said nominees.  Judgment upon the award rendered may be entered in the highest court or forum, state, or federal, having jurisdiction; provided,
          however, that the provisions of this Section 17.12 shall not apply to any dispute or controversy as to which any treaty or law prohibits such arbitration.  The prevailing party shall be entitled to reasonable attorneys’ fees and costs to be fixed
          by the arbitrators.
