Eden written notice within twenty (20) days after PHC’s receipt of such marketing materials will constitute PHC’s approval thereof. The
copyright in any such marketing materials (including, without limitation, any translation, adaptation and/or modification) will be owned by Eden,
subject to PHC’s Trademark rights.

3. Exclusive Supply
Agreement.

3.1 Supply Agreement. PHC hereby
grants to Eden an exclusive, worldwide right and license for the Term to sell the Compositions as a part of the Products in the H&G
Market.

3.2 Exclusivity. Eden’s
rights under this Section 3 will be exclusive in the Territory during the Term. PHC represents and warrants to Eden that PHC has not entered into any
other distribution, supply or sales representative agreements, written or oral, with any third party permitting the sale of the Compositions (or any
products incorporating the Compositions) in the H&G Market in the Territory as of the Effective Date. PHC covenants and agrees that during the
Term, PHC will not enter into any such agreement or itself sell or distribute the Compositions (or any products incorporating the Compositions) in the
H&G Market in the Territory or permit any third party to do so. Notwithstanding the terms of this Section 3.2, PHC will not be precluded from

plant nurseries.

3.3 Distribution;

the issuance of the Me Too Registrations described at Section 4.2 and subject to applicable laws, Eden may grant supplemental distribution rights under

reasonable efforts to ensure that such subdistributors comply with the applicable provisions of this Agreement. Notwithstanding any appointment of
subdistributors pursuant to this Section 3.3, Eden will remain fully responsible for the performance of all of its covenants and obligations hereunder,
and for such subdistributor’s compliance with all Eden’s covenants and obligations hereunder.

3.4 Promotion of the Products.
Eden will not, and will ensure that none of its subdistributors (a) promote, market, sell or distribute any Products for use in any jurisdiction within
the Territory where any applicable Regulatory Approval has not been obtained; or (b) make any representations or warranties concerning the Products on

PHC, on a quarterly basis, a rolling, non-binding annual estimate of upcoming orders. All Purchase Orders will be subject to the terms and conditions
of this Agreement, and will be expressly limited to the terms of this Agreement. Except as to quantity and shipping requirements set forth on each
applicable Purchase Order, additional or contrary terms proposed by either party, whether in the form of the Purchase Order, invoice, acknowledgement,
confirmation or otherwise, will be inapplicable, and the terms of this Agreement will control in the event of any conflict between such terms and the
terms of this Agreement. PHC will give Eden written notice accepting or rejecting each Purchase Order submitted by Eden in accordance with this
Agreement within ten (10) days after PHC’s receipt of the Purchase Order. If PHC rejects any Purchase Order submitted by Eden, PHC’s notice
of rejection will specify the reasons for rejection. PHC must accept a Purchase Order submitted by Eden to the extent the Purchase Order complies with
this Agreement.

3.7 Delivery Terms. All
deliveries by PHC will be to an address in the United States identified by Eden in the Purchase Order. Upon delivery, title will pass to Eden and PHC
will have no further responsibility or risk of loss, except as may otherwise be provided in Sections 7 and 8.

3.8 Inspection of Product. Eden
or its representative will inspect all Compositions promptly upon receipt, and in the event of any shortage, damage or discrepancy or in the event any
of the Compositions fail to comply with the then Specifications (except for defects not readily observable by Eden without opening the packaging
thereof), Eden will report the same to PHC within fifteen (15) days after receipt, in which event Eden will furnish written evidence or other
documentation, as appropriate. If the substantiating evidence delivered by Eden reasonably demonstrates that such shortage, damage, discrepancy or
nonconformity with Specifications existed at the time of delivery, Eden may return the Compositions to PHC at PHC’s expense and, at Eden’s
request and option, PHC will either promptly replace the Compositions in accordance with the delivery procedures set forth herein or refund or credit
Eden’s account for the full invoice value, together with any commercially reasonable shipping, inspection and return costs incurred by Eden. Any
Compositions not rejected by Eden by written notice to PHC within fifteen (15) days after delivery (other than Compositions containing latent defects
not readily observable by Eden) will be deemed to have been accepted by Eden. Following acceptance, the sole remedies of Eden with respect to
nonconformities, damage or defects in the Compositions will be those set forth in Section 7.

3.9 Price. PHC will supply the
Compositions to Eden at a price equal to eighty percent (80%) of PHC’s actual United States agricultural distributor price for such Compositions,
net of all final rebates or other allowances given (“Actual Price”). If necessary, PHC will extend price reductions to Eden after
delivery to reflect the difference in the Actual Price and the price originally invoiced, by providing to Eden the equivalent in value of free goods or
credits against the next Purchase Order placed by Eden. Upon request, PHC will provide Eden with a written certification confirming the Actual Price
for any order period. Each party will be responsible for their own taxes, fees, charges or assessments of any nature levied by any governmental
authority in connection with the transactions under by this Agreement.

3.10 Payment. PHC will invoice
Eden upon delivery and payment will be due to PHC within thirty (30) days of the invoice date. Payment will be made to an address provided by PHC or by
wire transfer to an account designated by PHC. Any wire transfer or other EFT fees are for PHC’s account. In the event of a dispute with regard to
amounts owing, Eden will timely pay any undisputed amounts and the parties agree to cooperate in good faith to promptly resolve any disputed amounts.
PHC will have the right to charge Eden a delinquent payment service charge on the amount of any fees not paid when due at a rate equal to the lesser of
one and one-half percent (1-1/2%) per month (or portion thereof) or the highest rate permitted by law, whichever is lower. In the event of any
delinquent payment by Eden, such delinquency will not constitute a breach of this Agreement, but late fees will accrue and PHC, at its option, may
withhold delivery of any outstanding Purchase Orders and otherwise suspend PHC’s performance under this Agreement without liability until payment
is received.

4. Registrations and Regulatory
Approvals.

4.1 EPA Filings. Subject to
Sections 4.2 and 4.3 herein, PHC will, at its expense, maintain all Regulatory Approvals and applications for approval with the EPA for the
Compositions in jurisdictions within the Territory where they exist as of the Effective Date as set forth at Exhibit B. Pending issuance of the
Me Too Registrations in accordance with Section 4.2, PHC hereby grants to Eden the right of distribution under all existing and future registrations
for the Compositions or the Products (the “Distribution Rights”). Eden, at its option and expense, will be responsible for filings,
maintenance and applicable fees for any non-EPA Regulatory Approvals and all Distribution Rights. In the event PHC does not hold any Regulatory
Approval in a jurisdiction within the Territory in which Eden desires to obtain such Regulatory Approvals, Eden may, upon prior written consent from
PHC, which consent will not be unreasonably withheld or delayed, proceed to seek such Regulatory Approval in Eden’s name, at Eden’s
expense.

4.2 EPA Amendments; Me Too
Registrations. Promptly following the Effective Date, Eden will, at its own expense, seek New Product Me-Too Fast Track Registrations (“Me
Too Registration(s)”) under applicable EPA regulations for the home and garden applications of the Compositions. PHC agrees, at its own
expense, to cooperate and assist Eden, as reasonably requested by Eden, in providing access to and use of the

supporting data for such
registrations, together with any assistance, documentation, certifications, test results or other information necessary for Eden to undertake such
registrations. Concurrently with the filing of the Me Too Registrations, PHC will, at its own expense, submit a master label amendment to the EPA to
delete from the existing EPA registrations (a) the home and garden coverage from each EPA registration label, and/or (b) the inclusion of home and
garden applications in the agricultural sections of each EPA Composition master label registration. Upon issuance of the Me Too Registrations, Eden
will (a) cease use of the EPA registrations held in Eden’s name for any new Product production; (b) modify all future Product labels to reflect
the Me Too Registration numbers issued directly to Eden; and (c) will undertaken new filings in connection with its Me Too Registrations to replace any
existing registrations for subdistributors appointed in accordance with Section 3.3.

4.3 Abandonment of Registration.
Notwithstanding Section 4.1, PHC may, at its option, abandon any Regulatory Approval with respect to a Composition provided (a) PHC gives advance
notice of not less than ninety (90) days thereof to Eden; and (b) at Eden’s option and sole cost and expense, PHC assists in transferring
ownership of such Regulatory Approval and supporting data to Eden.

4.4 Labeling. Eden will be
responsible for the content of the labeling for the Products prior to their distribution and sale into the H&G Market, in accordance with
applicable law.

4.5 Inspection. Upon prior
written notice, PHC will cause Eden’s regulatory personnel to be provided with reasonable access from time to time to the facilities and records
of PHC related to the Compositions for the purpose of confirming PHC’s compliance with all applicable laws and regulations.

4.6 Records and Recall. In the
event of a recall of any of Product as a result of the inclusion of any Composition, Eden will cooperate with and assist PHC in effecting such recall.
PHC will pay, or reimburse Eden, for all reasonable out-of-pocket expenses of effecting such recall of Products distributed by Eden under this
Agreement, including any shipping costs related to returning recalled Products to PHC and replacing such recalled Products with new Products at
PHC’s expense; provided, however, that if the recall will have been caused by (a) any component of the Product other than the Compositions; or (b)
any breach of or default under this Agreement by Eden or any of its subdistributors, then Eden will bear all the costs and expenses of the
recall.

4.7 Export; Import. Unless
otherwise agreed upon by Eden and PHC, all Compositions will be delivered by PHC to Eden within the United States. Eden will be responsible for
obtaining all import and/or export licenses and permits as may be required to import and/or export the Products into and from countries selected by
Eden, in accordance with then prevailing laws and regulations of such countries, and PHC will cooperate with Eden in its efforts to obtain any such
approvals. All such licenses and permits will be maintained in the name of Eden, whenever feasible in accordance with prevailing laws and regulations.
PHC will cooperate fully with Eden in its efforts to obtain any such approvals.

5. Failure of

and qualify a Second Source to make the Compositions for sale to Eden under this Agreement subject to the following:

(a) within ninety (90) days after the

and

(c) Eden will promptly notify PHC of
the selection and qualification of any Second Source (including, without limitation, the name, address and telephone number of the Second Source, the

to Eden a license to the Licensed Intellectual Property solely to make or have made by a Second Source solely for Eden, use, distribute, sell, have
sold, import and otherwise commercialize and exploit the Compositions in the Territory (subject to the terms of this Agreement) during that portion of
the Term after the occurrence of a Failure of Supply with respect to such Compositions, subject to and in accordance with the
following:

(a) Eden will not exercise such license
until the occurrence of a Failure of Supply with respect to any Compositions and Eden’s giving the notice described in Section

Compositions directly from a Second Source then, notwithstanding any other provision of this Agreement, Eden will be responsible, and PHC will be
relieved of any responsibility, for assuring that the Compositions are manufactured, packaged and labeled by the Second Source in accordance with the
Regulatory Approvals;

(d) if the Second Source is a third
party, the license will include a right to sell any Compositions made pursuant to the license to Eden or its subdistributors for distribution as a part
of the Products in the Territory under this Agreement, but not the right to sell or distribute the Compositions to any other party;
and

(e) Eden, at its option, may record
evidence of this license with any applicable authorities in order to confirm and secure the rights hereunder.

expense, reasonable documentation, standard operating procedures and transition assistance to the Second Source to enable the Second Source to
manufacture and/or supply the Compositions; and

(b) PHC will provide, at its own
expense, a reasonable quantity of the seed used for fermentation and development of the Compositions.

5.4 Registrations. To the extent
permitted by applicable regulations, upon a Failure of Supply, PHC will assist the Second Source in securing all necessary rights under the Regulatory
Approvals.

5.5 Termination of Failure of
Supply. Any Failure of Supply initiated under this Section 5 may be terminated as follows: (a) at the sole option and election of Eden, a Second
Source may be terminated and the rights granted under this Section 5 concluded; or (b) upon the mutual agreement of the parties, PHC may resume
production and supply of the Compositions under the terms of this Agreement and any corresponding rights of the Second Source will be terminated by
Eden.

6. Intellectual Property
Rights.

6.1 Claims By and Against PHC.
PHC will have (a) the right to assert, or at its option settle, any claim or suit necessary to enforce its Intellectual Property rights (including
those in the Trademarks) against any third party; and (b) the right to defend against, or at its option settle, any patent infringement
claim

relating to the Compositions made
by any third party against PHC. PHC agrees to provide Eden with commercially reasonable notice of each such claim or suit. PHC agrees to use
commercially reasonable efforts to enforce its Intellectual Property in the Compositions against any third party who PHC determines in its reasonable
judgment (after consultation with Eden) is infringing such Intellectual Property rights, provided that such infringement is likely to have a material
adverse impact on Eden’s sales of the Products. PHC will have sole control of the assertion or defense of any such action, including any appeals,
settlement or compromise thereof, and will have full authority to enter into a binding settlement or compromise; provided, however, that PHC will not
enter into any settlement or compromise that would obligate or affect Eden in an adverse manner with respect to its rights under this Agreement without
Eden’s consent, which consent will not be unreasonably withheld or delayed.

6.2 Claims Against Eden. PHC
will have the option (but not the obligation) to assume and defend any infringement claim made against Eden based upon the use of the Trademarks or the
Compositions in association with the Products. Eden will promptly notify PHC of any such claim and will offer to tender defense thereof to PHC. PHC
will promptly (and in no event later than 30 days after receipt of notice) notify Eden of its election or non-election to assume the defense of such
claim. In the event PHC elects to assume the defense of and responsibility for any claim under this Section 6.2, (a) at the request and expense of PHC,
Eden will reasonably assist PHC in the defense; (b) PHC will have sole control of the defense of any such action, including any appeals; and (c) PHC
will have full authority to enter into a binding settlement or compromise, provided, however, that PHC will not enter into any settlement or compromise
that would adversely affect Eden’s rights under this Agreement without Eden’s consent, which consent will not be unreasonably withheld or
delayed. In the event PHC refuses or fails to assume any defense under this Section 6.2, Eden may, at its sole option and expense, defend, settle or
otherwise compromise such claim, provided, however, that Eden will not enter into any settlement or compromise that would adversely affect PHC without
PHC’s consent, which consent will not be unreasonably withheld or delayed. PHC agrees to provide, at its own expense, any assistance reasonably
requested by Eden.

6.3 Limitation of Liability. PHC
will have no liability of any kind to Eden under this Section 6 to the extent any such claim is based solely upon or arises solely out of (a) any use
of any Trademark or Composition in a manner for which it was not approved, designed or intended to be used, as specified herein or in its labeling, if
and to the extent such use was promoted by Eden; (b) any modification of any Trademark or Composition by Eden that causes either of them to become
infringing; or (c) the use of any Composition in a manner inconsistent with the applicable Regulatory Approvals, if and to the extent such use was
promoted by Eden.

6.4 Replacement Product.
Notwithstanding the foregoing, if it is adjudicatively determined that a Trademark or Composition infringes, or, as a result of the Composition, a
Product that incorporates the Composition infringes, or in PHC’s reasonable opinion is likely to be found to infringe, a third party’s
Intellectual Property rights, or if the sale or use of such Composition or Product is, as a result, enjoined, then PHC will exercise commercially
reasonable efforts to either (a) procure for Eden the right under such third party Intellectual Property rights to sell the Products; or (b) modify the
Trademarks or Compositions, after consultation with Eden, to allow Eden to market a substitute Product.

6.5 Protection of Intellectual
Property. During the Term, PHC will be responsible (a) for prosecuting and maintaining all registrations and applications for the Patents and
Trademarks existing as of the Effective Date; and (b) to the extent it deems necessary or appropriate, for filing, prosecuting and maintaining any new
or additional Intellectual Property rights associated with the Compositions.

credit Eden’s account for any Composition that it reasonably determines did not comply with the warranty provided at Section 7.3 at the time of
delivery to Eden; provided, however, that PHC will have no obligation under this warranty to make replacements or grant credits necessitated, in whole
or in part, by (a) the failure of Eden to maintain any Compositions in accordance with any transportation, storage, handling or maintenance
instructions supplied by PHC; or (b) other fault or negligence of the Eden (except for any strict liability of PHC). Prior to returning any Composition
alleged to be defective, Eden will notify PHC in writing of the claimed defect, together with the original invoice number and date. No Composition will
be returned without first obtaining a returned goods authorization from PHC, which authorization will not be unreasonably withheld or
delayed.

7.5 Limited Warranty. THE
EXPRESS WARRANTIES OF EACH PARTY SET FORTH IN THIS SECTION 7 ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES OF EITHER PARTY, EXPRESS OR IMPLIED,
WHICH ARE HEREBY SPECIFICALLY DISCLAIMED, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE
OR USE. IN NO EVENT WILL EITHER PARTY’S LIABILITY TO THE OTHER PARTY UNDER THIS ARTICLE 7 EXTEND TO ANY SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES, INCLUDING WITHOUT LIMITATION, LOST PROFIT, GOODWILL OR TREBLE DAMAGES.

7.6 Limitation of Liability.
PHC’S OBLIGATION TO REPAIR OR REPLACE ANY COMPOSITION, OR TO CREDIT EDEN’S ACCOUNT FOR THE PURCHASE PRICE, WILL BE EDEN’S SOLE AND
EXCLUSIVE REMEDY FOR ANY BREACH OF WARRANTY UNDER THIS ARTICLE 7.3.

IN NO EVENT WILL PHC’S
LIABILITY TO EDEN UNDER SECTION 7.3 EXCEED THE TOTAL FEES PAID BY EDEN TO PHC FOR THE COMPOSITIONS GIVING RISE TO SUCH LIABILITY.

8. Indemnification and Limitation of
Liability.

8.1 Eden’s Indemnity. Eden
will indemnify, defend and hold harmless PHC, at Eden’s expense, from and against any Claims brought against or incurred by PHC arising from any
actions or omissions of Eden or its subdistributors in connection with the distribution and sale of the Products, including, without limitation, any
Claim based upon (a) a breach by Eden (or its subdistributors) of any representation, warranty or other obligation of Eden under this Agreement; (b)
the negligence or intentional misconduct of Eden, provided that in no event will Eden be liable for matters for which PHC is responsible under Section
8.2 or for punitive or exemplary damages; or (c) Product Liability Damages with respect to the failure of any Compositions produced by Eden or a Second
Source pursuant to Article 5. Eden will maintain product liability insurance or self-insurance in such amounts as ordinary good business practice for
its type of business would make advisable and will provide PHC with evidence of this coverage.

8.2 PHC’s Indemnity. PHC
will indemnify, defend and hold harmless Eden, at PHC’s expense, from and against any Claims brought against or incurred by PHC arising from any
act or omission of PHC or any third party acting on PHC’s behalf, including, without limitation, any Claim based upon (a) a breach of any
representation, warranty or other obligation of PHC under this Agreement; (b) the negligence or intentional misconduct of PHC, provided, however, that
in no event will PHC be liable for matters for which Eden is responsible for under Section 8.1 or for punitive or exemplary damages; and (c) Product
Liability Damages with respect to the failure of any Compositions purchased by Eden from PHC. PHC will maintain product liability insurance or
self-insurance in such amounts as ordinary good business practice for its type of business would make advisable and will provide Eden with evidence of
this coverage.

8.3 Limitation on PHC’s
Liability. PHC will not be liable under any circumstances to Eden (or to any third party, to the extent such limitation is permitted under
applicable law) for any special, indirect, consequential or punitive damages, including, but not limited to, loss of profits, loss of business
opportunities or loss of goodwill, even if advised of the possibility of such damages. EXCEPT FOR CLAIMS ARISING UNDER SECTIONS 8.2(B), 8.2(C), OR
9.1, IN NO EVENT WILL PHC’S LIABILITY FOR THE SUPPLY OF THE COMPOSITIONS TO EDEN EXCEED THE FEES PAID BY EDEN TO PHC FOR THE COMPOSITIONS GIVING
RISE TO SUCH LIABILITY, OR, IF SUCH LIABILITY DOES NOT RELATE TO SPECIFIC COMPOSITIONS, IN NO EVENT WILL PHC’S LIABILITY EXCEED THE AMOUNT OF FEES
PAID BY EDEN TO PHC FOR COMPOSITIONS PURSUANT TO THIS AGREEMENT DURING THE SIX (6) MONTH PERIOD IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO SUCH
LIABILITY. PHC will have no liability of any kind to Eden under Section 8.2 to the extent a claim is based solely upon or arises solely out of the
following: (a) the use of any Composition in a manner for which it was not designed or intended to be used as specified herein or in its labeling; (b)
any modification, alteration or damage to any Compositions by Eden or any third party that causes it to become unsafe; or (c) the use of any
Composition in a manner inconsistent with the applicable Regulatory Approvals in the jurisdiction of such use.

8.4 Limitation on Eden’s
Liability. Eden will not be liable under any circumstances to PHC (or to any third party, to the extent such limitation is permitted under
applicable law) for any special, indirect, consequential or punitive damages, including, but not limited to, loss of profits, loss of business
opportunities or loss of goodwill, even if advised of the possibility of such damages. EXCEPT FOR CLAIMS ARISING UNDER SECTIONS 8.1(B), 8.1(C) OR
9.1, IN NO EVENT WILL EDEN’S LIABILITY TO PHC EXCEED THE AMOUNT OF FEES PAYABLE BY EDEN TO PHC UNDER THIS AGREEMENT DURING THE SIX (6) MONTH
PERIOD IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO SUCH LIABILITY.

8.5 Procedure. If a Claim by a
third party is made and a party (the “Indemnitee”) intends to claim indemnification under this Article 8, the Indemnitee will promptly
notify the other party (the “Indemnitor”)

in writing of any Claim in respect
of which the Indemnitee, or any of its subsidiaries, directors, officers, employees, shareholders, suppliers, distributors or subdistributors, intends
to claim such indemnification and the Indemnitor will have sole control of the defense and/or settlement thereof, provided that the Indemnitee may
participate in any such proceeding with counsel of its choice at its own expense. The indemnity agreement in this Article 8 will not apply to amounts
paid in settlement of any Claim if such settlement is effected without the consent of the Indemnitor, which consent will not be unreasonably withheld
or delayed. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action will relieve
such Indemnitor of any liability to the Indemnitee under this Article 8 only to the extent such failure is adversely prejudicial to its ability to
defend such action. If the Indemnitor fails to provide defense of the Claim or to diligently defend or settle the same, the Indemnitee may defend or
settle the Claim without prejudice to its rights to indemnification hereunder, provided that the Indemnitee does so diligently and in good faith. The
Indemnitee may not enter into any settlement or agree to any stipulation that would adversely affect the rights of the Indemnitor or impose any
additional obligation on the Indemnitor without the providing prior written notice to the Indemnitor. The Indemnitee, its employees and agents, will
cooperate fully with the Indemnitor and its legal representatives and provide full information in the investigation of any Claim, in order to be
covered by this indemnification.

9.
Confidentiality.

9.1 Confidential Information.
Each party agrees to use commercially reasonable efforts to prevent any disclosure of the Confidential Information of the other party to any third
parties by its agents or employees. Upon any termination of this Agreement, any Confidential Information of a party that has been provided to the other
party will be returned upon written request.

9.2 Agreement Confidentiality.
In the event any party proposes to issue any press release or public announcement concerning any of the provisions of this Agreement or the
transactions contemplated hereby, such party will so advise the other party hereto, and the parties will thereafter use their best efforts to cause a
mutually agreeable release or announcement to be issued. Neither party will publicly disclose or divulge any provisions of this Agreement or the
transactions contemplated hereby without the other party’s written consent, except as may be required by any regulatory authority or by applicable
law or regulation to confirm a party’s rights or obligations hereunder, and except for communications to such party’s employees or customers,
or to investors or prospective investors, in each case subject to appropriate confidentiality obligations.

10. Term;
Termination.

10.1 Term. This Agreement will
take effect as of the Effective Date and will continue until the expiration of the last of the Patents to expire. Thereafter, this Agreement will
automatically extend for additional consecutive five (5) year periods. Notwithstanding the foregoing, Eden may terminate this Agreement at any time,
with or without cause, provided a Failure of Supply is not then in effect, by giving not less than thirty (30) days’ written notice to
PHC.

10.2 Rights and Obligations on
Termination. Upon termination of this Agreement, the parties will have the following rights and obligations:

(a) termination of this Agreement will
not release Eden from the obligation to make payment of all amounts previously due and payable; and

(b) Eden may continue to sell any
Products on hand in the H&G Market in the Territory for a period of up to twelve (12) months after the effective date of termination, subject to
applicable Regulatory Approvals and provided any such continued sale of the Products shall be subject to the terms of this Agreement set forth at
Sections 2.3, 3.1, 7, 8, 9, 11 and 12.

10.3 Remedies in the Event of
Breach. Notwithstanding the terms of this Section 10, nothing in this Agreement will preclude either party from declaring the other party to be in
breach of its performance

obligations under this Agreement if
such party fails to cure any material breach within thirty (30) days after notice thereof from the other party. Upon a declaration of breach, (a) the
non-breaching party may seek recovery of monetary damages from the breaching party in a court of applicable jurisdiction; and (b) if PHC is the
non-breaching party, PHC may withhold delivery of any outstanding Purchase Orders and otherwise suspend its performance under this Agreement without
liability until such breach is remedied by Eden. PHC’s failure to fulfill any outstanding Purchase Orders or to supply Compositions to Eden, or
PHC’s suspension of its performance under this Agreement, due to Eden’s uncured material breach shall not constitute a Failure of
Supply.

11.
Miscellaneous.

11.1 Relationship of the
Parties. Each party is an independent contractor to the other in the operation and administration of this Agreement. Nothing in this Agreement will
be construed as creating a partnership or joint venture between the parties.

11.2 Compliance with Laws. PHC
and Eden will each be responsible for compliance with present and future applicable statutes, laws, ordinances and regulations of national, federal,
state and local governments in the Territory now or hereafter in effect relating to all activities with respect to the Products and compliance with
this Agreement.

11.3 Governing Law and
Compliance. This Agreement will be governed by the internal substantive laws of the Commonwealth of Pennsylvania without respect to its conflicts
of law principles. The parties agree that the exclusive jurisdiction and venue of any legal action arising out of this Agreement will be the state or
federal courts located in Pittsburgh, Pennsylvania, and each party hereby submits itself to the exclusive jurisdiction and venue of those courts for
the purposes of such action. Notwithstanding the above, PHC, in its sole discretion, may bring an action against Eden in any other court of competent
jurisdiction.

11.4 Assignment. Neither party
will assign their rights or obligations under this Agreement without the prior written consent of the other party, which consent will not be
unreasonably withheld or delayed; provided, however, that either party may: (a) assign this Agreement in its entirety to a wholly owned and controlled
affiliate or an affiliate under common control and ownership; or (b) assign this Agreement to a successor to all or substantially all of such
party’s business or assets by way of acquisition or merger, provided such successor assumes and agrees to perform all of the obligations of the
assignor under this Agreement. Notwithstanding the foregoing, in the event PHC assigns any part of its business or obligations in any manner that
prevents Eden from having adequate supply of or ability to purchase the Compositions, such event will be deemed a Failure of Supply as of the effective
date of such assignment by PHC, and the provisions of Section 5 herein will apply.

11.5 Complete Agreement. This
Agreement, and the Exhibits hereto, constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements whether written or oral relating hereto.

11.6 Waiver, Amendment. The
failure of either party to enforce at any time any of the provisions of this Agreement will not, absent an express written waiver signed by such party
specifying the provision being waived, be construed to be a waiver of any such provision, nor in any way to affect the validity of this Agreement or
any part thereof or the right of the party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement will be held
to be a waiver of any other or subsequent breach. Any amendment to this Agreement will be in writing and signed by both parties.

11.7 Notices. All notices or
other communications to a party required or permitted hereunder will be in writing and will be delivered personally or by facsimile (receipt confirmed
electronically) to such party (or, in the case of an entity, to an executive officer of such party) or will be sent by a reputable express delivery
