5. GENERAL PROVISIONS. 
 a.
Relationship. Notwithstanding any provision hereof, for all purposes of this Agreement each party shall be and act as an independent contractor and not as partner, joint venturer, employer, employee or agent of the other and shall not
bind nor attempt to bind the other to any contract. Provider is an independent contractor and is solely responsible for all taxes, withholdings, and other statutory or contractual obligations of any sort, including, but not limited to, Workers’
Compensation Insurance. 
 b. Governing Law. This Agreement shall be governed by and construed in accordance with the
laws of the Commonwealth of Massachusetts without regard to its conflicts of law provisions. Exclusive jurisdiction and venue for any action arising under this Agreement is in the federal and state courts located in Massachusetts, and both parties
hereby consent to such jurisdiction and venue for this purpose. In any action or proceeding to enforce this Agreement, the prevailing party will be entitled to recover from the other party its costs and expenses (including reasonable attorneys’
fees) incurred in connection with such action or proceeding and enforcing any judgment or order obtained. 
 c.
Remedies. Provider acknowledges and agrees that in the event of any breach or threatened breach of Section 2 or 3, Company will suffer irreparable damage for which it will have no adequate remedy at law. Accordingly, Company shall
be entitled to injunctive and other equitable remedies to prevent or restrain, temporarily or permanently, such breach or threatened breach, without the necessity of proving actual damages or posting any bond or surety, in addition to any other
remedy that Company may have at law or in equity. 
 d. Notice. Any notice required or permitted to be given hereunder
will be effective upon receipt and shall be given in writing, in English and delivered in person, via established express courier service (with confirmation of receipt), confirmed facsimile or registered or certified mail, postage prepaid, return
receipt requested, to the parties at their respective addresses given herein or at such other address designated by written notice. 

e. Assignment. This Agreement and the performance contemplated hereunder are personal to Provider and Provider shall not
have the right or ability to subcontract, delegate, assign or otherwise transfer any rights or obligations under this Agreement without the prior written consent of Company. Any attempt to do otherwise shall be void and of no effect. Company may
transfer this Agreement without the consent of Provider. This Agreement will be binding upon, and inure to the benefit of, the successors, representatives and permitted assigns of the parties.

 f. Miscellaneous. This Agreement constitutes the entire agreement, and
supersedes all prior negotiations, understandings or agreements (oral or written), between the parties concerning the subject matter of this Agreement (and all past dealing or industry custom). Headings are for convenience of reference only and
shall in no way affect interpretation of the Agreement. This Agreement may be executed in one or more counterparts, each of which is an original, but taken together constituting one and the same instrument. Execution of a facsimile copy shall have
the same force and effect as execution of an original, and a facsimile signature shall be deemed an original and valid signature. No change, consent or waiver to this Agreement will be effective unless in writing and signed by the party against
which enforcement is sought. The failure of a party to enforce its rights under this Agreement at any time for any period will not be construed as a waiver of such rights. Unless expressly provided otherwise, each right and remedy in this Agreement
is in addition to any other right or remedy, at law or in equity, and the exercise of one right or remedy will not be deemed a waiver of any other right or remedy. In the event that any provision of this Agreement is determined to be illegal or
unenforceable, that provision will be limited or eliminated to the minimum extent necessary so that this Agreement will otherwise remain in full force and effect and enforceable.
