such expected inability. The period from the date of any such Notice until the date of a further Notice from Senetek that it expects to be able to resume fulfilling orders within such sixty (60) day period shall be deemed a Disruption

manufacturer designated by Licensee with Seneteks approval, not to be unreasonably withheld or delayed) shall have a non-exclusive license to use the Intellectual Property to produce those Products which are involved in the inability to fill
purchase orders referred to in Section 3.7, and Senetek agrees to assist Licensee in taking over manufacturing by providing such manufacturing records, recipes and other Confidential Information as may reasonably be required by them for such

and shipping the same to Licensees designated address therefor. Notwithstanding the foregoing, unless otherwise approved by Senetek in its sole discretion, Licensee or its permitted contract manufacturer shall purchase their requirements of
Kinetin solely from Senetek or its authorized vendor. The interim license granted by this Section 3.8 shall terminate automatically at the end of the Disruption Period, and neither Licensee nor any permitted contract manufacturer shall be

the foregoing shall be referred to as an infringement) relating to any of the Intellectual Property or any patent, trademark or other intellectual property of Licensee related to the Products, wherever and whenever such infringement or
act shall come to the attention of such party. Senetek (in the case of infringement of the Intellectual Property) or Licensee (in the case of infringement of its intellectual property) shall promptly take such commercially reasonable action as is
required to restrain such infringement or otherwise enforce its rights, and the other party shall cooperate fully in such action and, if so requested, shall join as a party to any appropriate legal proceedings for such purpose. Each party shall bear
its own expenses in connection with the foregoing. If within 30 days after the owner of the intellectual property being infringed becomes aware of such infringement, such party fails to commence appropriate and diligent action with respect to such
infringement, the other party shall have the right, to the extent permitted by law, to institute an action for infringement at its own expense, and in its own name, or in the name of any of its Affiliates and the right to enforce and collect any
judgment thereon.

8.2 Recovery.Any recovery by either party as a result of any claim, demand, litigation or other action
contemplated by Section 9.1 or any settlement thereof shall first be used to reimburse each party for the reasonable costs of the action borne by such party (or, if the recovery is less than the aggregate costs of such action, shall be
distributed between the parties in proportion to the costs of the action borne by each of the parties), with the remaining amount, if any, to be paid to the party bringing the action.

9. TERM AND TERMINATION

9.1 Term. The term of this Agreement shall be the Term as defined in
Article 1 unless terminated earlier than therein provided pursuant to this Article 10.

9.2 Termination for Cause. Each party shall
have the right to terminate this Agreement at any time upon written notice to the other in the event (i) the other party is found in breach of any of its representations or fails to perform any material obligation and such failure continues for
a period of thirty (30) days with respect to a payment failure or, with respect to any other failure, such failure continues for a period of sixty (60) days after notice thereof or (ii) the other party is declared insolvent or
bankrupt by a court of competent jurisdiction, or a voluntary petition of bankruptcy is filed in any court of competent jurisdiction by the other party, or the other party makes or executes any assignment for the benefit of creditors.
Notwithstanding the foregoing, in the case of a breach by Licensee of its covenants with respect to the Minimum Purchase Commitment, Licensee shall have the right to cure such breach by payment to Senetek of an amount equal to the Base Price payable
on the number of Units by which Licensee failed to achieve the Minimum Purchase Commitment (calculated assuming that Licensee ordered an equal quantity of each sku of Senetek Product).

9.3 Licensee Termination.Licensee may terminate this Agreement effective at the end of any
Contract Year upon written notice given to Senetek not less than 90 days prior to the end of the then current Contract Year.

9.4
Bankruptcy of Senetek.The parties hereby agree that licenses under this Agreement are licenses of intellectual property as defined in Section 101(35A) (formerly Section 101(56)) of the Bankruptcy Code, and that this license
agreement is governed by Section 365(n) of the Bankruptcy Code. Senetek hereby agrees that in the event this Agreement is assigned to any third party in any bankruptcy action by Senetek, such assignee must assume all of Seneteks
obligations under this Agreement.

10. MISCELLANEOUS

10.1 Method of Payments. All payments due under this Agreement shall be paid in U.S. Dollars by personal check, subject to collection, or wire transfer of immediately available funds to Senetek in the United
States. Payment shall be due and payable net thirty (30) days from date of invoice. Late payments shall be subject to a monthly processing fee of one-and-one-half percent (1.5%) of the amount overdue or, if such amount is not permitted by
law, the maximum amount permitted by law.

10.2 Taxes.All taxes due with respect to the sales of Products by Licensee shall be paid
by it. If Senetek is required to collect and remit any tax for which Licensee is responsible, Senetek shall be entitled to collect the amount of such tax from Licensee within 30 days of the date any such tax is due together with a handling charge of
five percent (5%) of the amount remitted.

10.3 No Joint Venture. It is not the intent of the parties hereto to form any
partnership or joint venture. Each party shall, in relation to its obligations hereunder, act as an independent contractor, and nothing in this Agreement shall be construed to give either party the power or authority to act for, bind or commit the
other.

10.4 Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of
California (regardless of that or any other jurisdictions choice of law principles). Licensee irrevocably submits to the exclusive jurisdiction of the United States Federal District Court for the Northern District of California for all
purposes related to enforcement of this Agreement.

10.5 No Assignment. Neither party to this Agreement may assign its rights or
obligations under this Agreement without the prior written consent of the other party to this Agreement; provided, however, that either party may assign its rights to an Affiliate or to any successor by merger, consolidation, sale of stock or
the sale of substantially all of the assets of such party; provided further, that no such permitted assignment shall relieve the assigning party of its liability for any breach by its assignee. Licensee may not sub-license any of its rights



13



---

hereunder without the prior written consent of Senetek. Any permitted sublicense shall require that the sub-licensee
agree in writing to comply with the terms of this Agreement and shall name Senetek as a third-party beneficiary with rights of enforcement. No sub-licensee shall have any right to grant additional sublicenses, and any attempt to grant such a further
sublicense shall automatically terminate the sub-license under which such additional sub-license purportedly was granted.

10.6 Force
Majeure. No party hereto shall be liable to any other in damages for, nor shall this Agreement be terminable by reason of, any delay or default in such partys performance hereunder if such delay or default is caused by conditions beyond
such partys control including, but not limited to, acts of God, regulation or law or other action of any government or any agency thereof, war, insurrection, civil commotion, destruction of production facilities or materials by earthquake,
fire, flood or storm, labor disturbances, epidemic, or failure of suppliers, public utilities or common carriers. Each party hereto agrees to promptly notify the other party of any event of force majeure under this Section 10.6 and to employ
best efforts towards prompt resumption of its performance hereunder if such performance is delayed or interrupted by reason of such event. In the absence of a force majeure event involving material impairment or destruction of manufacturing
capability or supply chain for Product, no force majeure event shall be deemed to excuse the failure of Licensee to meet the Minimum Purchase Commitment applicable to any Contract Year.

10.7 Notices. Unless otherwise provided herein, any notice required or permitted to be given hereunder (a Notice) shall be
mailed by certified mail or generally recognized express courier service with signature required for delivery, postage prepaid, sent by facsimile transmission, or delivered by hand to the party to whom such Notice is required or permitted to be
given hereunder, at such partys address first set forth above or at such other address as the party may have designated by Notice hereunder. If mailed, any such Notice shall be deemed to have been given as of the date of receipt, as evidenced
by the date appearing on the delivery notice. If delivered by hand, any such Notice shall be deemed to have been given when received by the party or agent of such party to whom such Notice is given, as evidenced by written and dated receipt of the
receiving party.

10.8 Captions. The captions in this Agreement are solely for convenience of reference and shall not be used for
purposes of interpreting or construing the provisions hereof.

10.9 Severability. Should any part or provision of this Agreement be
held unenforceable or in conflict with the applicable laws or regulations of any jurisdiction, the invalid or unenforceable part or provision shall be replaced with a provision which accomplishes, to the extent possible, the original business
purpose of such part or provision in a valid and enforceable manner, and the remainder of this Agreement shall remain binding upon the parties hereto.

10.10 Waiver. No failure on the part of any party hereto to exercise, and no delay in exercising, any right, privilege or power hereunder shall operate as a waiver or relinquishment thereof; nor shall any
single or partial exercise by any party hereto of any right, privilege or power hereunder preclude any other or further exercise thereof, or the exercise of any other right, privilege or power.

agreement and understanding between the parties hereto with respect to the subject matter of this Agreement and shall supersede any prior agreements, negotiations, understandings, representations, statements and writings relating thereto. This
Agreement may not be amended or modified except in a writing signed by a duly authorized officer of the party against whom enforcement of such amendment is sought.

10.12 Counterparts. This Agreement may be executed in one or more counterparts by exchange of facsimile copies of signature pages, each of which will be deemed an original and all of which together will
constitute one and the same instrument.

SCHEDULE 6.2

DISPUTE RESOLUTION

Any dispute between the parties arising out of or relating to this Agreement,
including with respect to the interpretation of any provision of this Agreement or with respect to the performance by either party, shall be resolved as provided in this Schedule.

(a) Informal Dispute Resolution.

The parties shall in good faith first attempt to resolve their dispute on an informal basis through discussions between a designated representative of each party, as follows. Either party may initiate this informal resolution process (the
Disputing Party) by sending a notice to the other party outlining to such other party the nature of the dispute and the name and contact information of the officer of the Disputing Party who shall act as its designated representative.
Within (7) days of receipt of such notice, the receiving party shall by notice designate an officer who shall act as that partys designated representative. The designated representatives shall meet at a mutually acceptable time and place
within fourteen (14) days of the date the initial notice was received and thereafter as often as they reasonably deem necessary. No communication made during this period between the parties concerning the dispute may be used by either party in
any subsequent proceeding for any reason.

(b) Arbitration.

If the parties are unable to resolve the dispute informally, within twenty-one (21) days of the date the initial notice was received, either party
may commence a mandatory and binding arbitration concerning such dispute, in accordance with the following procedures:

(i)
Selection of Arbitrator. The party making demand for arbitration (the Demanding Party) shall notify the American Arbitration Association (the AAA) and the other party in writing describing in reasonable detail the
nature of the dispute (the Demand for Arbitration), and shall request that the AAA furnish a list of five (5) possible arbitrators who shall have substantial experience in the area of patent licensing and shall otherwise be
qualified to competently address the issues presented. Each party shall have fifteen (15) days to reject two (2) of the proposed arbitrators. If only one individual has not been so rejected, he or she shall serve as arbitrator. If two
(2) or more individuals have not been so rejected, then the parties shall promptly mutually select the arbitrator from the remaining pool of possible arbitrators; provided, however, that if the parties are unable to agree on such selection
within ten (10) days after notification by the AAA of the need to make such selection, then the AAA shall select the arbitrator from the remaining pool of possible arbitrators.

(ii) Conduct of Arbitration.

(A) The arbitrator shall allow reasonable discovery in the forms permitted by the United States Federal Rules of Civil Procedure, consistent with the purpose of the arbitration. Such discovery shall be completed no
later than sixty (60) days following the appointment of the arbitrator.



25



---

(B) Following the conclusion of the discovery period, the arbitration hearing shall be
commenced promptly and conducted expeditiously, with each of the parties being limited to no more than a total of five (5) business days for the presentation of its case, including any rebuttal or cross-examination. Unless otherwise agreed by
the parties, the arbitration hearing shall be conducted on consecutive business days. Strict rules of evidence shall not be applied in the arbitration hearing. The arbitrator shall control the presentation of evidence and accord it such weight as
the arbitrator deems appropriate. Cross-examination of witnesses and rebuttal testimony may be permitted.

(C) Each party
may submit one pre-arbitration brief (of not more than twenty (20) pages (excluding exhibits)), and a list of proposed witnesses setting forth a brief summary of their testimony, no later than five (5) days prior to the commencement of the
arbitration hearing, and may also submit one post-arbitration hearing brief (of not more than ten (10) pages (excluding exhibits)) no later than five (5) days after the close of the arbitration hearing. A copy of any brief or document
submitted to the arbitrator shall also be served on the other party.

(D) The arbitrator shall have no power or authority to
amend or disregard any provision of this Schedule or any other provision of the Agreement (in particular, the arbitrator shall not have the authority to exclude the right of a party to terminate the Agreement when a party would otherwise have such
rights or to assess damages in excess of or different than those provided under the Agreement).

(E) Except when a conflict
exists between the terms of the Agreement and the rules of commercial arbitration of the AAA in effect at the time of arbitration, the arbitrator shall use the rules of commercial arbitration of the AAA in effect at the time of the arbitration.

(iii) Replacement of Arbitrator. Should the arbitrator refuse or be unable to proceed with arbitration proceedings
as called for by this Schedule, such arbitrator shall be replaced by an arbitrator selected according to the procedures stated above.

(iv) Authority of Arbitrator to Rule. The parties hereby agree and consent that the arbitrator shall be fully authorized and empowered to (i) permit and rule on motions of summary judgment made by either
of the parties and (ii) award injunctive relief. The ruling of the arbitrator, including on any motion of summary judgment or concerning any award of injunctive relief, shall be final and binding on the parties, and may be confirmed in any
court of competent jurisdiction.

(v) Findings and Conclusions. The arbitrator rendering judgment upon disputes
between the parties may prepare and distribute to the parties a writing describing the findings of fact and conclusions of law relevant to the judgment and award and containing an opinion setting forth the reasons for the giving or denial of any
award.



26



---

The award of the arbitrator shall be final and binding on the parties, and judgment thereon may be
entered in a court of competent jurisdiction.

(vi) Place of Arbitration. Arbitration, including any necessary
hearings hereunder, shall be held in San Francisco, California. If the parties agree, arbitration hearings may be held in another location.

(vii) Time of the Essence. The arbitrator is instructed that time is of the essence in the arbitration proceeding, and that the arbitrator shall have the right and authority to issue monetary sanctions against
either of the parties if, upon a showing of good cause, that party is unreasonably delaying the proceeding. The arbitrator shall render his or her judgment or award within fifteen (15) days following the conclusion of the hearing. Recognizing
the express desire of the parties for an expeditious means of dispute resolution, the arbitrator shall limit or allow the parties to expand the scope of discovery as may be reasonable under the circumstances. In no event shall the period of time
from the date of delivery to the other party of a partys demand for arbitration to the arbitrators rendering of his or her judgment exceed one hundred eighty (180) days.

(viii) Confidentiality. The parties agree that the existence of a dispute, any efforts or proceedings to resolve a dispute, whether
informal or pursuant to arbitration, and any rulings or decisions issued by the arbitrator pursuant to this Schedule, shall be held in confidence in accordance with the terms and conditions of this Agreement.

(ix) Costs and Expenses. The parties shall jointly and equally pay the expenses of the arbitrator and administrative costs assessed
by the AAA.

(c) Litigation.

(i) Immediate Injunctive Relief. The parties agree that the only circumstance in which disputes between them shall not be subject to the arbitration provisions of this Schedule is when a party makes a good
faith determination that it needs and is entitled to receive a temporary restraining order or other emergency injunctive relief in order to protect its interest during the pendency of an arbitration proceeding. If a party files a pleading with a
court seeking immediate injunctive relief and this pleading is challenged by the other party and the injunctive relief sought is not awarded in substantial part, the party filing the pleading seeking immediate injunctive relief shall pay all of the
costs and attorneys fees of the party successfully challenging the pleading.

(ii) Jurisdiction. The parties
consent to jurisdiction and venue in the Northern District of California for all litigation that may be brought, subject to the requirement for arbitration hereunder, arising out of or relating to this Agreement, including with respect to the
interpretation of any provision of this Agreement or with respect to the performance by either party. The parties further consent to the jurisdiction of any state or provincial court located within a district which encompasses assets of a party
against which judgment has been rendered, either through arbitration or through litigation, for the enforcement of such judgment or award against the assets of such party.

(d) Governing Law.

Disputes subject to this Schedule, and all proceedings to resolve such disputes, shall be governed by and proceed in accordance with, the laws of the
jurisdiction whose laws govern the Agreement.
