It is the intention of the Seller that such release of the Seller Released Claims shall be effective as a bar to each and every demand, claim and proceeding hereinabove specified and in furtherance of such intention, and the Seller, hereby expressly waives, effective as of the Closing Date, any and all rights and benefits conferred upon the Seller under applicable law and expressly agrees that this release will be given full force and effect according to each and all of its express terms and provisions, including those related to unknown and unsuspected demands and proceedings, if any, as those relating to any other demands and proceedings hereinabove specified, but only to the extent such provision is applicable to releases such as this Section 4(c)(i).

(ii) As a material inducement for the Seller to enter into this Agreement, effective as of the Closing Date, the Company, on behalf of itself and each of its Affiliates, managers, predecessors, assigns and successors (collectively, the “Company Parties”), hereby unequivocally, voluntarily, knowingly, willingly, unconditionally, completely, irrevocably and immediately remises, releases and discharges the Seller and each of its assigns and successors (collectively, the “Seller Released Persons”) from and with respect to any and all Losses of whatever kind or nature to the extent arising on or prior to the Closing Date, whether at law, equity or otherwise, whether now known or unknown, and whether or not concealed or hidden, which any of the Company Parties now has, or has ever had or may hereafter have against any of the Seller Released Persons occurring at any time on or prior to the Closing Date in connection with (A) the acquisition, ownership, transfer, sale or disposition of the Shares, and (B) the Seller’s acts or omissions in its capacity as a stockholder, Founder, director or employee of the Company or its Affiliates, as applicable (the “Company Released Claims”); provided that the Company Released Claims shall not include (1) any claims pursuant to this Agreement, and (2) any claims that may not be released as a matter of law.

Section 1542 provides:

A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.

(iv) Each of the parties hereto, on behalf of itself, its successors and assigns, acknowledges that its own legal counsel has explained the effect and importance of the provisions of Section 1542, and of a waiver of the provisions of Section 1542. With this knowledge and understanding, each of the parties hereto, on behalf of itself, its successors and assigns, waives and relinquishes any rights or benefits that it has or might have under Section 1542 or any similar law enacted in any other jurisdiction. Each of the parties hereto, on behalf of itself, its successors and assigns, acknowledges that it is aware that it might hereafter discover facts in addition to or different from those that it now knows or believes to be true with respect to the subject matter of this Agreement, but it is the intention of the Seller and the Company (A) hereby to fully and finally forever settle and release any and all matters, disputes and differences, known or unknown, suspected and unsuspected, arising out of, based upon, or relating to, any and all claims, and (B) that the releases contained in Section 4(c)(i) and Section 4(c)(ii) shall remain in effect as full and complete general releases, notwithstanding discovery of, or the existence of, any such additional or different facts.

(d) Non-Compete.

(i) The Seller hereby agrees not to compete with any products or services currently offered by the Company, as such business of the Company is described in the that certain Registration Statement of the Company confidentially submitted on Form S-1 to the Securities and Exchange Commission (which the Seller acknowledges it has reviewed) (any such business, a “Competitive Business”) for three years following the Closing Date. Notwithstanding the foregoing, coffee, pill, juice and powder supplement products used for inflammation and anti-aging, that do not contain protein, will not constitute a Competitive Business.

6

(ii) Notwithstanding the foregoing, nothing herein shall prohibit the Seller, directly or indirectly, through an Affiliate or otherwise, from (A) owning, acquiring, holding or disposing of any investment, directly or indirectly, comprising not more than five percent (5%) of the fully-diluted equity interests of any publicly traded or privately held entity engaged in a Competitive Business, (B) performing any services for the Company or any of its subsidiaries, or (C) from owning, acquiring, holding or disposing of any interest in any private equity, venture capital or other investment fund that is managed by a third party investment manager, so long as the Seller has no participation in the governance or operation of such investment fund with respect to any Competitive Business.
