         it is essential that any noncompetition covenant with respect thereto
         cover all of the Business and the entire Territory.

                  (d) Severability. In the event a judicial or arbitral
         determination is made that any provision of this Section 7.6
         constitutes an unreasonable or otherwise unenforceable restriction
         against the Company or the Seller, the provisions of this Section 7.6
         shall be rendered void only to the extent that such judicial or
         arbitral determination finds such provisions to be unreasonable or
         otherwise unenforceable with respect to the Company or the Seller. In
         this regard, any judicial authority construing this Agreement shall be
         empowered to sever any portion of the Territory, any prohibited
         business activity or any time period from the coverage of this Section
         7.6 and to apply the provisions of this Section 7.6 to the remaining
         portion of the Territory, the remaining business activities and the
         remaining time period not so severed by such judicial or arbitral
         authority. Moreover, notwithstanding the fact that any provision of
         this Section 7.6is determined not to be specifically enforceable, the
         Purchaser shall nevertheless be entitled to recover monetary damages as
         a result of the breach of such provision by the Company or the Seller.
         The time period during which the prohibitions set forth in this Section
         7.6shall apply shall be tolled and suspended for a period equal to the
         aggregate time during which the Company or the Seller violates such
         prohibitions in any respect.

                  (e) Injunctive Relief. Any remedy at law for any breach of the
         provisions contained in this Section 7.6 shall be inadequate and the
         Purchaser shall be entitled to injunctive relief in addition to any
         other remedy the Purchaser might have hereunder.

         Section 7.7 Release. In consideration for entering into this Agreement,
the Company, the Purchaser, the Seller and the individual signatories appended

"Releasor(s)"), on the date hereof, knowingly, voluntarily and unconditionally
release, forever discharge, and covenant not to sue the individuals and entities
listed on Schedule 7.7 (the "Releasees") from or for any and all claims, causes
of action, demands, suits, debts, obligations, liabilities, damages, losses,
costs and expenses (including attorneys' fees) of every kind or nature
whatsoever, known or unknown, actual or potential, suspected or unsuspected,
fixed or contingent, that such Releasor has or may have, now or in the future to
the end of the world, arising out of, relating to, or resulting from any act or
omission, error, negligence, breach of contract, tort, violation of law,
discrimination, matter or cause whatsoever from the beginning of time or in the
future to the end of the world; provided, however, that the foregoing release
shall not apply to any claims arising out of this Agreement. Each party hereto
agrees that notwithstanding anything else in this Agreement, the provisions of
this Section 7.7 shall survive Termination of this Agreement.

         Section 7.8 Certain Agreements. Effective on the Closing Date, the
Company and the Seller agree to terminate: (i) the Administrative Services
Agreement dated Janaury 6, 2006, (ii) the Investor Registration Rights Agreement

2006 by and among the Company, the Seller and the holders of the Series A
Preferred Shareholders, shall be deemed to have consented to the consummation of
a "Spin-Off Transaction" at the behest of the Seller and waive the other

Spin-Off Instruction, pursuant to Article III.C.5.(a) as set forth in the
Company's Certificate of Incorporation, that the Company, at its sole
discretion, shall use its commercially reasonable efforts to file and cause to
