     confidential, or proprietary nature concerning the Disclosing Party's
     technology, business, business relationships, or financial affairs in

          Party or otherwise in violation of the Disclosing Party's rights, or

          Confidential Information received from the Disclosing Party.

     c.   TERM. The Receiving Party shall observe all obligations hereunder with

          three (3) years after the particular Confidential Information was
          received from the Disclosing Party. The terms of this section will
          survive the termination of this Agreement.

     d.   TITLE AND PROPRIETARY RIGHTS. Notwithstanding the disclosure of any

          trademark, trademark notice, copyright notice, confidentiality notice,
          or any notice of any other proprietary right of the Disclosing Party

     f.   THIRD-PARTY INFORMATION. The parties agree that the terms of this
          section extend to such types of information, materials, and tangible
          property of third parties who may have disclosed or entrusted the same
          to either party with the expectation of confidentiality.

6.   Approval Process: Company shall have the right to inspect, and accept or
     reject, any deliverable item under the Statement of Work. If within thirty
     (30) days of delivery of any deliverable item, Company determines in good
     faith that any item does not conform to any condition of this Agreement,
     the Statement of Work, or otherwise does not function properly, then in
     addition to any other remedy available to Company, Company may return such
     item to Contractor for correction or modification. Contractor shall, at its
     sole expense, correct or modify such item and deliver the same to Company
     as expeditiously as possible. Unless otherwise requested by Company and
     agreed to in writing by Contractor, failure to give Contractor notice of
     nonconformance within the thirty (30) day period will constitute acceptance
     of that deliverable item by Company.

7.   Ownership/Work for Hire: All inventions, discoveries, computer programs,
     data, technology, designs, innovations, and improvements (whether or not
     patentable and whether or not copyrightable) ("Inventions") related to the
     business of Company which are made, conceived, reduced to practice,
     created, written, designed, or developed by Contractor, solely or jointly
     with others, during the term of this Agreement or thereafter if resulting
     or directly derived from Confidential Information (as defined in section 5
     above), shall be the sole property of Company. Contractor hereby assigns to
     Company all Inventions and any and all related patents, copyrights,
     trademarks, trade names, and other industrial and intellectual property
     rights and applications therefor, in the United States and elsewhere, and
     appoints any officer of Company as its duly authorized attorney to execute,
     file, prosecute, and protect the same before any government agency, court,
     or authority. Upon the request of Company, Contractor shall execute such
     further assignments, documents, and other instruments as may be necessary
     or desirable to fully and completely assign all Inventions to Company and
     to assist Company in applying for, obtaining, and enforcing patents or
     copyrights or other rights in the United States and in any foreign country
     with respect to any Invention. Contractor also hereby waives all claims to
     moral rights in any Inventions. Contractor shall promptly disclose to
     Company all Inventions and will maintain adequate and current written
     records (in the form of notes, sketches, drawings, and as may be specified
     by Company) to document the conception and/or first actual reduction to
     practice of any Invention. Such written records shall be available to and
     remain the sole property of Company at all times. Contractor agrees that it
     will obtain contractual obligations legally sufficient to effectuate its
     obligations under this section from its employees who provide services
     pursuant to this Agreement. Contractor shall provide copies of such
     agreements to Company. Company acknowledges that Contractor enters this
     Agreement already possessing substantial skill in the field in which
     Contractor has been retained, and this Agreement in no way limits
     Contractor's ability to use these skills in any other application that
     Contractor sees fit, except as set forth in section 8 below. In the work
     product provided to Company, Contractor is likely to use variants of
     algorithms, software development and testing techniques, architectures,
     structures, and design methodologies that are known in the art or to
     Contractor, and nothing in this Agreement shall limit or prevent Contractor
     from reusing these techniques under contract to others or for the purposes
     of Contractor's own developments, except as set forth in section 8 below.

8.   Non-Competition: During the term of this Agreement and for a period of [**]
     thereafter, neither party to this Agreement shall, directly or indirectly,
     disclose, discuss, modify, release, transfer, or otherwise make known in
     any way any aspect of the other party's Confidential Information to any
     other entity at any time. Contractor agrees not to internally develop and
     market products that compete with Company's computer hardware products. No
     term of this Agreement shall limit either party from developing competing
     products under contract to or in partnership with other entities, except
     that Contractor agrees not to develop competing computer hardware products.
     Neither party may use the Confidential Information of the other party in
     the development of such products.

9.   Non-Solicitation: During the term of this Agreement and for one (1) year
     thereafter, neither party will directly or indirectly recruit, solicit, or
     induce any employee, advisor, or consultant of the other party to terminate
     his or her relationship with that party.

10.  Property Rights: Contractor agrees to deliver promptly all Company's
     property and all copies of Company's property in Contractor's possession at
     any time upon Company's request. Upon termination of this Agreement for any
     reason, Contractor agrees to deliver promptly to Company all such
     documents, whether in written, graphical, or electromagnetic form, together
     with any other of Company's property then in Contractor's possession,
     except as Company may, by prior written approval, allow Contractor to
     retain.

11.  Termination: This Agreement may be terminated by either party at any time
     upon fifteen (15) days written notice. In the event of termination of this
     Agreement, all provisions herein with respect to confidentiality,
     ownership, and property rights shall remain in force. Upon receipt of such
     notice from Company, Contractor shall cease providing services, advise
     Company of the extent to which Contractor has completed the services
     through such date, and collect and deliver to Company whatever work product
     then exists. Company shall make a final payment to Contractor for all work
     performed through the date of such termination, net thirty (30) days.

12.  Notices: All notices hereunder shall be given in writing by hand delivery,
     courier service, US Mail, or facsimile, addressed to the signatories of
     this Agreement at the respective addresses set forth in the first paragraph
     of this Agreement, or at such addresses as may from time to time be
     designated by either party to the other.

13.  Waiver: No failure by either party hereto to exercise and no delay in
     exercising any right hereunder shall operate as a waiver thereof, nor shall
     any single or partial exercise of any right hereunder by either party
     preclude any other or future exercise of any right hereunder by that party.

14.  No Subcontract: Contractor agrees that no work under this Agreement shall
     be subcontracted to any party without Company's prior written consent, and
     that only Contractor and/or its employees will perform the work hereunder.
     In the event of any permitted subcontract, the subcontracting party must be
     bound by the terms of sections 2, 3, 5, 7, 9, 10, 11, and 12 of this
     Agreement.

15.  Assignment: This Agreement is not assignable by either party in whole or in
     part without the written consent of the other party.

16.  Severability: The invalidity or unenforceability of any provision of this
     Agreement shall not affect the validity or enforceability of any other
     provision of this Agreement.

17.  Equitable Remedies: The restrictions contained in this Agreement are
     necessary for the protection of the business and goodwill of Company and
     are considered by Contractor to be reasonable for such purpose. Contractor
     agrees that any breach of this Agreement is likely to cause Company
     substantial and irrevocable damage and therefore, in the event of any such
     breach, Contractor agrees that Company, in addition to such other remedies
     which may be available, shall be entitled to specific performance and other
     injunctive relief.

18.  Governing Law: This Agreement is governed by and will be construed as a
     sealed instrument under and in accordance with the laws of the Commonwealth
     of Massachusetts (without reference to the conflicts of laws provisions
     thereof). Any action, suit, or other legal proceeding which is commenced to
     resolve any matter arising under or relating to any provision of this
     Agreement shall be commenced only in a court of the Commonwealth of
     Massachusetts (or, if appropriate, a federal court located within
     Massachusetts), and Company and Contractor each consents to the
     jurisdiction of such a court.

19.  Entire Agreement: This Agreement supersedes all prior agreements, written
     or oral, between Contractor and Company relating to the subject matter of
     this Agreement. This Agreement may not be modified, changed, or discharged
     in whole or in part, except by an agreement in writing signed by Contractor
     and Company. Contractor agrees that any change or changes in the services
     to be performed or payment terms after the signing of this Agreement shall
     not affect the validity or scope of this Agreement.
