5.1.

The Consultant shall perform all Services under this Agreement as an “independent contractor” and not as an employee or agent of the Company or a Portfolio Company.

5.2.

The Consultant shall have the right to control and determine the time, place, methods, manner and means of performing the Services. In performing the Services, the amount of time devoted by the Consultant on any given day will be entirely within the Consultant’s control, and the Company or a Portfolio Company will rely on the Consultant to put in the amount of time necessary to fulfill the requirements of this Agreement. The Consultant will provide all equipment and supplies required to perform the Services. The Consultant is not required to attend regular meetings at the Company or a Portfolio Company. However, upon reasonable notice, the Consultant shall meet with representatives of the Company or a Portfolio Company at a location to be designated by the parties to this Agreement.

5.3.

In the performance of the Services, the Consultant has the authority to control and direct the performance of the details of the Services, the Company or a Portfolio Company being interested only in the results obtained.

5.4.

The Consultant shall not use the Company’s or a Portfolio Company’s trade names, trademarks, service names or servicemarks without the prior approval of the Company or a Portfolio Company.

5.5.

The Consultant shall be solely responsible for all state and federal income taxes, unemployment insurance and social security taxes in connection with this Agreement and for maintaining adequate workers’ compensation insurance coverage.

Remedies. The Consultant acknowledges that any breach of the provisions of Section 4 of this Agreement is likely to result in serious and irreparable injury to the Company or a Portfolio Company for which the Company or a Portfolio Company cannot be adequately compensated by monetary damages alone. The Consultant agrees, therefore, that, in addition to any other remedy it may have, the Company or a Portfolio Company is entitled to seek to enforce the specific performance of this Agreement by the Consultant and to seek both temporary and permanent injunctive relief (to the extent

permitted by law) without the necessity of proving actual damages or posting a bond.

Indemnification. The Consultant shall be solely liable for, and shall indemnify, defend and hold harmless the Company or a Portfolio Company and its successors and assigns from and against any claim or liability of any kind (including penalties, fees or charges) resulting from the Consultant’s failure to pay the taxes, penalties, and payments referenced in Section 5 of this Agreement. The Consultant shall further indemnify, defend and hold harmless the Company or a Portfolio Company and its successors and assigns from and against any and all loss or damage resulting from any misrepresentation, or any non-fulfillment of any representation, responsibility, covenant or agreement on her part, as well as any and all acts, suits, proceedings, demands, assessments, penalties, judgments of or against the Company or a Portfolio Company arising out of the Consultant’s gross negligence in the provision of Services hereunder.

8.	Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and the Consultant.

Non-Assignability of Contract. This Agreement is personal to the Consultant and the Consultant shall not have the right to assign any of her rights or delegate any of her duties without the express written consent of the Company. Any non-consented-to assignment or delegation, whether express or implied or by operation of law, shall be void and shall constitute a breach and a default by the Consultant.

10.	Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without giving effect to any choice or conflict of law provision or rule that would cause the application of laws of any other jurisdiction.

11.

Successors and Assigns. This Agreement shall be binding upon, and inure to the benefit of, both parties and their respective successors and assigns, including any corporation with which, or into which, the Company may be merged or which may succeed to its assets or business, provided, however, that the obligations of the Consultant are personal and shall not be assigned by him.

12.

Third Party Beneficiaries. Consultant and the Company acknowledge and agree that any Portfolio Company is an intended third-party beneficiary of this Agreement to the extent such provisions cover or are applicable to any Portfolio Company. The Portfolio Company shall have the right to enforce such provisions of this Agreement against the Consultant, as though the Portfolio Company was a party thereto, with respect to such provisions.

13.

Interpretation. If any restriction set forth in Section 4 is found by any court of competent jurisdiction to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, it shall be interpreted to extend only over the maximum period of time, range of activities or geographic area as to which it may be enforceable.

14.	Survival. Sections 4 through 15 shall survive the expiration or termination of this Agreement.

15.	Miscellaneous.

15.1.

No delay or omission by the Company in exercising any right under this Agreement shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar or waiver of any right on any other occasion.

15.2.

The captions of the sections of this Agreement are for convenience of reference only and in no way define, limit or affect the scope or substance of any section of this Agreement.

15.3.

In the event that any provision of this Agreement shall be invalid, illegal or otherwise unenforceable, the validity, legality and enforceability of the remaining provisions shall in no way be affected or impaired thereby.
