          for CEE and Cambridge to operationally fulfill all of its educational

          amended (the "Contracts") in the manner and at the same level of
          quality that they were fulfilled previously by Cambridge (the
          "Services").

     (b)  C-bridge shall be the exclusive provider of all Services necessary for
          CEE or, Cambridge to fulfill operationally their obligations under the
          Contracts until the first anniversary hereof and shall be a non-
          exclusive provider thereafter.

     2.   Personnel.
          ---------

     (a)  C-bridge has hired certain employees of Cambridge ("Cambridge
          Employees") in order to provide the services specified in Section 1
          above. Should the employment of any of such Cambridge Employees by C-
          bridge terminate for any reason, C-bridge shall promptly notify CEE
          and begin its customary procedures to replace the employee. CEE must
          approve the hiring of any such replacement employees and their further
          respective replacements, if any, throughout the Term and such approval
          shall not be unreasonably withheld.

                                       1

     (b)  C-bridge must obtain the approval of CEE if it wishes to change the
          duties of any Cambridge Employees involved in the delivery of the
          Services and such approval shall not be unreasonably withheld.

     (c)  C-bridge will maintain the same level of headcount as currently
          involved in the delivery of the Services.

     3.   Compensation and Expenses.
          -------------------------

     (a)  As a fee for the service provided pursuant hereto, CEE will pay C-
          bridge $479,049.00 in advance on the first business day of every month
          throughout the Term.

     (b)  For services rendered pursuant hereto and performed elsewhere than in
          the vicinity of 219 Vassar Street, CEE shall reimburse C-bridge for
          all out-of-pocket travel, food, lodging, shipping, communication, and
          related expenses incurred in the course of rendering such services
          ("Reimbursable Expenses") to the extent that it receives reimbursement
          pursuant to a Contract. All Reimbursable Expenses shall be
          appropriately documented in reasonable detail by C-bridge.

     (c)  If for any reason, C-bridge ceases to maintain the headcount
          requirement of Section 2(c) and CEE or Cambridge provides such
          headcount themselves, whether through employment or contract, then CEE
          may invoice C-bridge, and C-bridge shall pay, for CEE's or Cambridge's
          costs of such headcount for such time periods as such headcount is so
          maintained, provided that the amount of CEE's invoice to C-bridge
          shall not exceed the total compensation plus payroll tax expenses for
          such headcount and be comparable to prior costs associated with the
          headcount.

     (d)  All invoices rendered pursuant to paragraphs 3(b) and (c) hereof shall
          be due and payable net 30 days from receipt.

     (a)  Each party (an "Indemnifier") hereby agrees to defend, indemnify and
          hold harmless the others from and against any and all claims, losses,
          and expenses, including reasonable attorneys' fees and other costs of
          litigation, based upon or arising out of any negligent or willful acts
          or omissions of the Indemnifier.

     (b)  Notwithstanding the preceding paragraph, C-bridge's liability under
          this Agreement is limited to the amount of the fee receivable by C-
          bridge under the terms of this Agreement. In no event will C-bridge
          have any liability for any special, indirect, or consequential damages
          including, without limitation damages for lost profits or costs of
          procurement of substitute goods or services, arising in any way out of
          this Agreement under any cause of action, whether or not C-bridge has
          been advised of the possibility of such damages. These limitations
          will apply notwithstanding the failure of the essential purpose of any
          limited remedy.

     5.   Assignment. C-bridge may not assign this Agreement without the
          ----------
approval of Cambridge or CEE. Cambridge or CEE may not assign this Agreement

          ------------------

     (a)  The relationship of C-bridge to CEE and Cambridge established by this
          Agreement is that of independent contractors, and nothing contained in

          direct and control the-day to-day activities of the other, (ii)
          constitute the parties as partners, joint ventures, co-owners or
          otherwise as participants in a joint or common undertaking, or (iii)

          other for any purpose whatsoever.

     (b)  This Agreement contains the entire understanding of the parties with
          respect to the provision of any services by C-bridge to CEE and
          Cambridge. No waiver, consent, modification, amendment, or change of
          the terms of this Agreement shall be effective unless made in writing
          and signed by the parties hereto. This Agreement supercedes all
          previous agreements concerning the subject matter hereof, except that
          C-bridge shall still be liable to pay the Promissory Note it made in
          payment for the tangible assets of Cambridge it purchased pursuant to
          the April Agreement.

     (c)  Neither party to this Agreement shall be liable to the other by reason
          of any failure in performance of this Agreement in accordance with its
          terms if such failure arises out of causes beyond the control and
          without the fault or negligence of such party. Such causes include but
          are not limited to acts of God or of the public enemy, acts of civil
          or military authority, fires, strikes, unavailability of energy
          resources, delay in transportation, riots, war, the state of Prof.
          Donovan's health, a lack of timely payments of fees or expenses by HP
          or Oracle under their respective Contracts, or the breach of contracts
          by third parties. A party so disabled shall promptly and in writing
          advise the other party if it is unable to perform due to such a force
          majeure event, the expected duration of such inability to perform, and
          of any developments (or changes therein) that appear likely to affect
          the ability of that party to perform any of its obligations hereunder
          in whole or in part.

     (d)  All notices and other communications under this Agreement shall be in
          writing and shall be deemed given when delivered personally, by
          certified mail, return receipt requested, by reputable overnight
          courier, or by confirmed facsimile transmission to the other party at
          the address set forth above and to the attention of the signatory
          below (or to such other address or fax number or to the attention of
          such other person as a party may have specified by notice given to the
          other party pursuant to this provision) and shall be deemed received
          when actually delivered or refused.

     (e)  This Agreement shall be governed by and construed under the laws of
          the Commonwealth of Massachusetts without regard to the principles of
          conflict of law and all parties hereby consent to the personal and
          exclusive jurisdiction and venue in the state and federal courts
          sitting in the Commonwealth of Massachusetts. Process may be served on
          either party by using the notice provisions of Section 9(d) above
          except as prohibited by law.

     (f)  If any provision of this Agreement is held to be invalid by a court of
          competent jurisdiction, the remaining provisions shall remain in full
          force and effect. The parties agree to replace any invalid provision
          with a valid provision which most closely approximates the intent and
          economic effect of the invalid provision.
