3.3 Stock Issuance. 
 3.3.1. Intellectual Property Purchase Shares. Within eight (8) days after the Separation Date, PURE shall issue to Singer three hundred thousand (300,000) shares of its restricted

provided for Singer and her eligible family members by PURE shall continue uninterrupted, at the sole cost and expense of PURE, for a period of twelve (12) months following the Separation Date (the “Extended Coverage Period”).
If PURE cannot provide direct coverage for Singer as a consultant, then upon timely election by Singer of continued group coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), PURE shall
either pay directly or reimburse Singer for the COBRA premium payments for Singer and her eligible family members under PURE’s group medical, dental and vision plans. In the event that PURE discontinues or changes group insurance coverage, the
obligation to provide or reimburse Singer for substantially similar coverage will continue through the Extended Coverage Period. At the end of the Extended Coverage Period, health insurance coverage for Singer and her eligible family members shall
cease unless pursuant to applicable law Singer makes a proper election to further continue such coverage, if available. All such coverage beyond the Extended Coverage Period, if any, will be solely at the expense of Singer and subject to the terms
and conditions of the documents governing the health insurance plan. 
 3.5 Complete Release and Hold Harmless.
Singer, on behalf of herself, her spouse, her heirs, personal representatives, successors, assigns and all others claiming through or under her, and PURE, for itself and its successors and assigns, hereby agree to release, discharge, and hold
harmless each other and their respective directors, officers, affiliates, and attorneys, and each of their successors and assigns, from any and all known and unknown claims of every nature and kind whatsoever which they now or hereafter may have
with respect to each other and/or the Released Claims, notwithstanding Section 1542 of the California Civil Code, which provides that: 
 “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, AND WHICH IF KNOWN BY HIM, MUST HAVE MATERIALLY
AFFECTED HIS SETTLEMENT WITH THE DEBTOR.” 
 All rights under §1542 of the California Civil Code are hereto
expressly, fully, knowingly and intentionally forever waived and relinquished by the Parties. All Parties hereby acknowledge that each understands the significance and consequences of such specific waiver under §1542 of the California Civil
Code, and that each has had the opportunity to seek the advice of legal counsel of their choosing. 
 3.6 Scope of
Singer’s Release. Singer further expressly understands that the rights being waived 

  
 3 

 
hereunder specifically include, but are not limited to, any and all claims under (as any of the same may be amended from time to time) Title VII of the Civil Rights Act of 1964; Sections 1981 and
1983 of the Civil Rights Act of 1866; Equal Pay Act; Americans with Disabilities Act; Age Discrimination in Employment Act; Singer Retirement Income Security Act; Fair Labor Standards Act; Family and Medical Leave Act; WARN Act; the United States
and California Constitutions; California Fair Employment and Housing Act; California Family Rights Act; California Labor Code; any applicable California Industrial Welfare Commission Wage Order; with respect to the foregoing constitutional and
statutory references, any comparable constitution, statute or regulation of any other state; all claims of discrimination or harassment on account of race, sex, sexual orientation, national origin, religion, disability, age, pregnancy,
veteran’s status, or any other protected status under any federal or state statute; any federal, state or local law enforcing express or implied employment contracts or covenants of good faith and fair dealing; any federal, state or local laws
providing recourse for alleged wrongful discharge or constructive discharge, termination in violation of public policy, tort, physical or personal injury, emotional distress, fraud, negligent misrepresentation, defamation, and any similar or related
claim; together with any claim under any other local, state or federal law or constitution governing employment, discrimination or harassment in employment, or the payment of wages or benefits, whether or not now known, suspected or claimed, which
Singer ever had, now has, or may claim to have as of the date of this Agreement. This Agreement and the scope of the release by Singer hereunder expressly includes any statutory claims, including, but not limited to, claims under the Age
Discrimination in Employment Act (the “ADEA”) and the Older Workers’ Benefit Protection Act (“OWBPA”), except that this Agreement does not waive rights or claims under the ADEA, or otherwise, which may arise
after the Effective Date of this Agreement. 
 3.7 After Acquired Information. The Parties acknowledge that
they may hereafter discover information, facts, or circumstances different from or in addition to those which they now know or believe to be true. Except as otherwise provided herein to the contrary, this Agreement shall remain in full force and
effect in all respects notwithstanding such discovery, and in accordance with the irrevocable waiver and relinquishment of provisions of California Civil Code Section 1542 or otherwise, the Parties expressly accept and assume the risk of such
possible additions to or differences from those facts now known or believed to be true. 
 3.8 Enforceability. The
enforceability of this Agreement is conditioned upon each respective Party satisfying its respective obligations hereunder. 

3.9 Assignment of Released Claims. The Parties hereby covenant that none of the Released Claims has been assigned to any
other person, and that no other person has any interest in any of the Released Claims. In the event any other person asserts any interest with respect to the Released Claims, then the Party breaching this covenant shall indemnify the Party against
whom such claim is asserted for any and all damages, costs, and fees. 
 3.10 Specific Exclusion. It is expressly
understood that the release contained in this Agreement does not encompass the promises and obligations of the Parties under this Agreement. This Agreement also does not contemplate or include within the release hereunder post-Effective Date
intentionally willful, tortious, or criminal acts of either Party, such acts being expressly excluded from this Agreement. 

3.11 No Admission of Liability. Notwithstanding the terms and conditions of this Agreement, execution hereof shall in no
manner or form constitute the admission of liability or of responsibility by either Party in respect to the Employment Relationship or otherwise. 
 3.12 Closing. The transactions and initial payments envisioned hereunder shall be held at a closing (the “Closing”) as part of a meeting of the Board of Directors of PURE. All
terminations and appointments shall be effected at the Closing. The obligation to make the payment of the Separation Payment under Section 3.2.1. is expressly dependent upon and arises on the terminations and appointments provided for herein.
It is further expressly agreed by the Parties: 
 (a) All terminations and appointments at the Closing shall be made in advance
of the 

  
 4 

 
Separation Payment. However, such terminations and appointments shall be null and void in the event of the failure to timely satisfy the Separation Payment. 

(b) The Parties recognize that the funds to satisfy the Separation Payment will be transferred to PURE as of the date of the Closing (the
“Closing Date”). PURE shall provide to Singer evidence of the transfer of the funds on the Closing Date. 
 (c) So
long as evidence is presented to Singer that the funds have been transferred to PURE as of the Closing Date then Singer agrees to delay receipt of the Separation Payment until the funds have been cleared by PURE’s bank as being available for
payment by PURE, but in no case more than seventy-two (72) hours after the Closing. 
 IV

Employment Agreement are hereby null and void.

acknowledges that she is not entitled to receive, and will not claim, any damages, rights, benefits, or compensation other than as expressly set forth in this Agreement. 
 4.5 Return of Materials. Upon execution of this Agreement Singer shall promptly deliver to PURE all equipment, notebooks, documents, memoranda, reports, files, samples, books,
correspondence, lists, computer disks and data bases, computer programs and reports, computer software, and all other written, graphic and computer generated or stored records relating to the business of PURE which are or have been in the possession
or under the control of Singer, in addition to all property owned by PURE which is in her possession or under her control, including though not limited to credit cards, entry cards, identification badges and keys. The Parties have agreed that
certain electronics will be retained by Singer after having been properly cleared by PURE. 
 4.6 Consulting
Relationship. As additional consideration in exchange for the Severance Payment and Purchase of Intellectual Property, Singer agrees to provide consulting services to PURE for no additional charge from the Separation Date up to and until
twelve (12) months thereafter (the “Consulting Period”). It is the express intention of PURE that Singer performs services during the Consulting Period as an independent contractor to PURE. Nothing in this Agreement shall in

provide ongoing access to her Intellectual Property as described below and to reasonably assist and advise PURE on all aspects of PURE’s business and obligations whether arising prior to or after the Separation Date. As such, as additional
consideration for the Purchase Shares upon issuance Singer 

  
 5 

 
hereby irrevocably sells, assigns, and transfers to PURE all of Singer’s clients, contacts, and personal goodwill not previously assigned to PURE or that developed in the course of the
Consulting Relationship as referred to in Section 4.6.

 5.5 Non-Solicitation of Business. During and throughout the forty-eight (48) months immediately following

that are directly or indirectly disparaging, derogatory or damaging to PURE or any of its respective past, current or future affiliates, officers, directors, shareholders, employees, consultants, advisors, representatives, trustees, subsidiaries,
divisions, parent companies, clients or customers or their policies and procedures, business, practices or financial condition; and, (ii) PURE will not make or cause to be made any statements or remarks (including, without limitation, the

 VII 

INTENDED TAX RESULTS 
 7.1 Excise Tax. The Parties believe that the payments and issuance under this Agreement do not constitute “excess parachute payments” under Section 280G of the Internal
Revenue Code of 1986, as amended (the “Code”), or any successor provision. Notwithstanding such belief and intent, if any payment or benefit due under this Agreement, together with all other payments and benefits (including, without
limitation, equity-based compensation awards) to which Singer is entitled from PURE, would (if paid or provided) constitute an “excess parachute payment”, the amounts otherwise payable and benefits otherwise due under this Agreement will
either (i) be delivered in full, or (ii) be limited to the minimum extent necessary to ensure that no portion thereof will fail to be tax-deductible to PURE by reason of Section 280G of the Code, whichever of the foregoing amounts,
taking into account the applicable federal, state or local income and employment taxes and the excise tax imposed under Section 4999 of the Code, results in Singer’s receipt, on an after-tax basis, of the greatest amount of benefits,
notwithstanding that all or some portion of such benefits may be subject to the excise tax imposed under Section 4999 of the Code. In the event that the payments and/or benefits are to be reduced pursuant to this Section 7.1, such payments
and benefits shall be reduced such that the reduction of compensation to be provided to Singer as a result of this Section 7.1 is minimized. In applying this principle, the reduction shall be made in a manner consistent with the requirements of
Section 409A of the Code and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis but not below zero. No reduction or limitation under this
Section 7.1 shall apply to payments made for the purchase of intellectual property from Singer by PURE. 
 7.2
Compliance with Section 409A.

 7.2.1. Intent. The intent of the Parties is that payments and benefits under
this Agreement comply with Section 409A of the Code and the regulations and guidance promulgated thereunder (collectively “Section 409A”). Accordingly, to the maximum extent permitted, this Agreement shall be interpreted
to be in compliance therewith. If Singer notifies PURE (with reasonable specificity as to the reason therefor) that Singer believes that any provision of this Agreement (or of any award of compensation, including equity compensation or benefits)
would cause Singer to incur any additional tax or interest under Section 409A and PURE concurs with such belief or PURE (without any obligation whatsoever to do so) independently makes such determination, PURE shall, after consulting with
Singer, reform such provision to attempt to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order
to comply with Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit/burden to Singer and PURE of the applicable provision without
violating the provisions of Section 409A. 
 7.2.2. Specific Provisions. A termination of employment shall
not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service”
within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service”. If Singer
is deemed on the date of termination to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then with regard to any payment or the provision of any benefit that is specified as subject to
this Section or that is otherwise considered deferred compensation under Section 409A payable on account of a “separation from service,” and that is not exempt from Section 409A as involuntary separation pay or a short-term
deferral (or otherwise), such payment or benefit shall be made or provided at the date which is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from service” of Singer, and
(ii) the date of Singer’s death (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 7.2.2. (whether they would have otherwise been payable in a single sum
or in installments in the absence of such delay) shall be paid or reimbursed to Singer in a lump sum without interest, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment
dates specified for them herein. 
 7.2.3. Reimbursement. With regard to any provision herein that provides for
reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, (ii) the amount of
expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year, provided that the foregoing clause
(ii) shall not be violated without regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect and
(iii) such payments shall be made on or before the last day of Singer’s taxable year following the taxable year in which the expense occurred. 
 7.2.4. Date of Payment. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be
within the sole discretion of PURE. 
 7.3 Tax Cooperation and Exchange of Information. Each Party shall cooperate
fully at such time and to the extent reasonably requested by the other Party in connection with the preparation and filing of any tax return or claim for refund, or the conduct of any audit, dispute, proceeding, suit, or action concerning any tax
issues or other tax matters considered in this Agreement. Such cooperation shall include, without limitation, the following: (i) the retention and provision on reasonable demand of books, records, documentation, or other information relating to
the tax matters under this Agreement; (ii) the provision of additional information, including an explanation of material provided under subparagraph (i), to the extent such information is

  
 10 

 
necessary or reasonably helpful in connection with the foregoing; (iii) the execution of any document that may be necessary or reasonably helpful in connection with the filing of a tax
return or in connection with any audit, dispute, proceeding, suit or action; and, (iv) such Party’s commercially reasonable efforts to obtain any documentation from a governmental authority or a third party that may be necessary or
reasonably helpful in connection with any of the foregoing. Each Party further agrees: (i) not to take any action reasonably expected to result in a new or changed position on a tax issues under this Agreement that is detrimental to the other
Party; and, (ii) to take any action reasonably requested by the other Party that would reasonably be expected to result in or produce a benefit or avoids a detriment to such other Party with regard to tax issues under this Agreement.
However, the preceding sentence and corresponding obligation shall not apply to any situation in which a Party’s tax and/or legal advisors determine in good faith that taking a position consistent with the position of the other Party
would violate any applicable state or federal rule or law, including without limitation generally accepted accounting principles, SEC reporting rules, and state or federal tax laws and regulations.

Parties hereby agree that the Superior Court of California, San Diego, shall be the sole jurisdiction and venue for the bringing of such action.

expressed written consent of all Parties. 
 8.13 Notices.
