ARTICLE X  
 OTHER
PROVISIONS 
 10.1 Assignment. Neither Party shall transfer or assign its interest in this Agreement, in whole or in part,
directly or indirectly, without the prior written consent of the other Party which consent will not be unreasonably withheld; except that Supplier may assign its rights and delegate its duties under this Agreement (i) by way of merger or sale
of all or substantially all of the ownership interests or assets of Supplier in one or a series of related transactions; (ii) to a subsidiary or an affiliate of Supplier upon notice to Customer together with an assumption of this Agreement by
such subsidiary or affiliate; or (iii) in connection with any financing. Supplier may also assign the right to receive any payments hereunder or under any Order to any third party, and Customer, on receiving notice of any such assignment, shall
abide thereby and make payment as may therein be directed. In the event of any permitted assignment of this Agreement by either Party, the designated assignee shall assume, in writing, the rights and obligations of the assigning Party under this
Agreement; provided that the assigning Party shall not be released from any of its liabilities or obligations arising under this Agreement prior to such assignment. 

10.2 Relationship. In connection with this Agreement, each Party is an independent contractor. This Agreement establishes and will only
be construed as establishing a contract for the provision and purchase of certain products and does not and will not be deemed to create a joint venture, partnership, fiduciary or agency relationship between the Parties for any purpose. Each of the
Parties understands and agrees that this Agreement does not create an exclusive dealings arrangement and that each of Customer and Supplier may enter into similar arrangements with others with respect to similar or the same products. With respect to
its own personnel, each Party is independently responsible for all obligations incumbent upon an employer.

 10.3 Entire Agreement; Amendment. This Agreement, including its appendices, exhibits and
schedules, (a) constitutes the entire Agreement between the Parties with respect to the subject matter hereof, (b) supersedes any existing agreements between them whether oral or written and (c) shall control and govern all
transactions between the Parties with respect to the sales and purchases of Product. The terms of this Agreement shall only be amended, modified or supplemented as set forth herein or in a writing signed by or on behalf of both of the Parties, which
writing must specifically reference and identify the provision of this Agreement to be modified and the intention to modify this Agreement must be explicitly stated. Acceptance of an Order is insufficient to amend this Agreement unless a separate
writing is duly executed by all the Parties specifically amending this Agreement. 
 10.4 Reformation. If any term or other provision
of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby are not affected in any manner materially adverse to any Party. Upon the determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate
in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. 

10.5 Notices. Any notice provided or permitted to be given under this Agreement shall be in writing, and may be served by personal
delivery, by registered or certified U.S. mail, addressed to the party to be notified, postage prepaid, return receipt requested; or by nationally recognized delivery service. Notice deposited in the mail in the manner hereinabove described shall be
deemed to have been given and received on the date of the delivery as shown on the return receipt. Notice served in any other manner shall be deemed to have been given and received only if and when actually received by the addressee. All notices
shall be addressed as follows: 
 If to Supplier: 

If to Customer: 
 Any party
may, by written notice so delivered to the other party, change the address or individual to which delivery shall thereafter be made. 
 10.6
Electronic Transmissions. Notices sent by facsimile or email transmission will not be effective for any purpose under this Agreement; and while in the course of normal contract administration the Parties may choose to use email transmissions
for convenience, all notices of a legal nature or required under the terms of this Agreement (such as, but not limited to, a notice of termination of this Agreement, dispute, claim, indemnification, default, or breach or failure to make payment)
must be given in accordance with Section 10.5 above. Except as otherwise set forth in Section 10.9, the Parties do not consent to conduct any of the transactions contemplated by this Agreement by electronic means, and
electronic notices and signatures shall not be effective except as provided in Section 10.9. 

  
 13 

 10.7 Waiver. No failure or delay by either Party in exercising any of its rights under
this Agreement shall be deemed to be waiver of that right, and no waiver by either Party of a breach of any provision of this Agreement shall be deemed to be a waiver of any subsequent breach of the same or any other provision. 

10.8 Governing Law; Venue; Waiver of Jury Trial. 

(a) This Agreement and all Orders and other instruments executed in accordance herewith governed by and construed in accordance with the laws
of the State of Delaware (except to the extent that mandatory provisions of federal law govern), without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause
the application of laws of any jurisdiction other than those of the State of Delaware. 
 (b) THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE
JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, IF THE COURT OF CHANCERY OF THE STATE OF DELAWARE OR THE DELAWARE SUPREME COURT DETERMINES THAT, NOTWITHSTANDING SECTION 111 OF THE DELAWARE GENERAL CORPORATION LAW, THE COURT OF

ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IS NOT SUBJECT THERETO OR THAT SUCH PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS AGREEMENT OR ANY SUCH DOCUMENT MAY NOT BE
ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES HERETO IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH PROCEEDING SHALL BE HEARD AND DETERMINED EXCLUSIVELY BY SUCH A DELAWARE STATE OR FEDERAL COURT. THE PARTIES HEREBY CONSENT TO AND GRANT
ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH PROCEEDING IN THE MANNER PROVIDED IN SECTION 10.5 OR IN SUCH OTHER
MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF. 
 (c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY
CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR ANY ORDERS OR OTHER INSTRUMENTS EXECUTED IN ACCORDANCE HEREWITH IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH 

  
 14 

 
PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS
AGREEMENT, ANY ORDERS OR ANY OTHER INSTRUMENTS EXECUTED IN ACCORDANCE HEREWITH. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT,
IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (ii) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (iii) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY, AND (iv) SUCH PARTY
HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, EACH ORDER AND EACH OTHER INSTRUMENT EXECUTED IN ACCORDANCE HEREWITH BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 10.8(C). 

(d) Any Party who substantially prevails (giving due consideration to all relevant circumstances and not merely to which party obtains a
judgment or recovery in its favor) in asserting or defending a claim or suit arising out of a transaction covered by this Agreement shall be awarded, in addition to all other damages allowed under law, its costs, fees and expenses, including
reasonable attorneys’ fees and costs. 
 10.9 Counterparts. This Agreement, any amendment to this Agreement or any Order may be
executed in one or more counterparts, each of which shall for all purposes be deemed to be an original and all of which shall constitute the same instrument. The exchange of copies of this Agreement, any amendment to this Agreement or any Order and
of signature pages by facsimile transmission (whether directly from one facsimile device to another by means of a dial-up connection or whether otherwise transmitted via electronic transmission), by electronic mail in “portable document
format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, or by a combination of such means, shall constitute effective execution and delivery of this
Agreement, such amendment to this Agreement or such Order, as applicable, as to the Parties and may be used in lieu of an original thereof for all purposes. Signatures of the Parties transmitted by facsimile or other electronic transmission shall be
deemed to be original signatures for all purposes. Minor variations in the form of signature pages of this Agreement, any amendment to this Agreement or any Order, including footers from earlier versions thereof, shall be disregarded in determining
