the Seller), including any and all obligations to make payments to Buyer under
Section 4(c) of the Asset Contribution Agreement,





(all such
obligations and liabilities being referred to collectively as the “Released
Obligations”).





1.3           Payment of

parties acknowledge that (i) under Section 4(c) of the Asset Contribution
Agreement the Company was obligated to pay Buyer the total amount of $600,000
payable in 120 monthly payments of $5,000 each, (ii) as of the date of this
Agreement $475,000 of such amounts remains unpaid (the “Installment

year end balance sheet of the Company (the “Balance
Sheet”), which will properly reflect any accrued or unpaid expenses for
the period ended December 31, 2008 and set forth the amount of all outstanding
financial obligations and accrued expenses of the Company as of December 31,
2008, excluding
the Installment Payment Balance (the “December
31, 2008 Accrued Obligation”).  The Balance Sheet and the
December 31, 2008 Accrued Obligation shall be binding and conclusive upon Buyer
and Seller unless Buyer, within 10 days after the date on which it received the
Balance Sheet, shall have notified Seller in writing of any objections thereto
(“Buyer’s
Objection Notice”).  Buyer’s Objection Notice shall specify in
reasonable detail the items in the Balance Sheet or the calculation of the

disputed and a description in reasonable detail of the reasons for such
dispute.





(d)           Buyer
and Seller will promptly negotiate with each other in an attempt to resolve any

they will promptly refer the dispute to a mutually acceptable independent
accounting firm (the “Disputes
Auditor”) for resolution in accordance with this Section
1.3.  The Disputes Auditor shall review only the items that are in
dispute and shall make its determination based upon the terms, conditions and
principles set forth in this Agreement and within the range of outcomes proposed
by Buyer and Seller.  Buyer and Seller agree that they will require
the Disputes Auditor to render its decision within 30 days after referral of the
dispute to the Disputes Auditor for decision pursuant hereto.  In the
absence of calculation and other similar manifest errors, the decision of the
Disputes Auditor shall be final and binding on all parties.  Judgment
may be entered upon the determination of the Disputes Auditor in any court
having jurisdiction over the party against which such determination is to be
enforced.  Buyer and Seller shall be responsible for their own costs
in respect of the preparation and review of the Balance Sheet.  All
fees and expenses of the Disputes Auditor shall be borne by the party that that
is not successful (or is least successful) in its position.





(e)           The
Balance Sheet and the calculation of the December 31, 2008 Accrued Obligation
shall become final and binding on all parties upon the earliest to occur of (i)
if no Buyer’s Objection Notice has been given, the expiration of the period
within which Buyer may notify Seller of any objections thereto pursuant to Section 1.3(c);
(ii) the agreement by Buyer and Seller that the Balance Sheet and the
calculation of the December 31, 2008 Accrued Obligation, together with any
modifications thereto agreed by them, shall be final and binding; and (iii) if a
matter has been submitted to the Disputes Auditor in accordance with this Section 1.3, the
date on which the Disputes Auditor shall issue its decision with respect
thereto.





(f)           Within
five business days following the date on which the December 31, 2008 Accrued
Obligation has become final and binding in accordance with Section 1.3(e) Seller
will pay to Buyer the amount of the December 31, 2008 Accrued Obligation, as
adjusted, where applicable, pursuant to any agreement between Buyer and Seller
or pursuant to the decision of the Disputes Auditor.


3





(g)           In
addition to the payment of the December 31, 2008 Accrued Obligation pursuant to
this Section 1.3, if at any time during the period ending on the date that is
six months after the date of this Agreement, Buyer becomes aware of an
additional liability or obligation of the Company that was outstanding or arose
during the period ending on December 31, 2008, it will promptly give written
notice of such obligation or liability to Seller (an “Additional
Liability Notice”).  An Additional Liability Notice shall
specify in reasonable detail the amount and basis for the additional liability
or obligation.  No later than 20 days after its receipt of the
Additional Liability Notice, Seller shall either pay the amount of the
additional liability or obligation or provide to Buyer notice in writing of any
objections thereto (a “Seller’s
Objection Notice”).  A Seller’s Objection Notice shall specify
in reasonable detail the reasons for such disputing the appropriateness of the
liability or obligation.  Buyer and Seller will resolve any dispute
concerning any Additional Liability Notice and any Seller’s Objection Notice in
accordance with the procedures set forth in Section 1.3 that are applicable to a
Buyer’s Objection Notice.
