NOW, THEREFORE, in consideration of the recitals, mutual covenants and agreements, and subject to the terms and conditions contained herein, the parties agree as follows:

1.	PURCHASE AND SALE OF BUSINESS ASSETS

1.1 Seller hereby agrees to sell, transfer, assign, and/or deliver to Buyer, and Buyer agrees to purchase and acquire from Seller on the terms and conditions set forth in this Agreement, all of Seller's right, title and interest in and to the following assets (collectively, the “Business Assets”):

Inventory. The inventory of the Business, including the actual quantities of goods on hand and other work in process (including its approximate stage of completion) and finished goods (the “Inventory”), as shown on Schedule A. The Inventory also includes all consumable supplies necessary to continue operations, including but not limited to, shipping boxes, lead pigs, labels and disposable lab materials.

Customer Accounts and Data and Distributor Contracts. All customer lists, customer files, customer contracts, customer histories, customer records, and distributor contracts which relate to the Business (“Customer Accounts and Distributor Contracts”) as well as all marketing material pertaining to the Business, such as trade booths and literature. The customers and distributors which are parties to contracts with Seller which relate to the Business and of market materials being transferred is set forth on Schedule B.

All trade names, trademarks, service marks, sealed source device registrations, and patents (whether registered or unregistered), and the registrations or applications for registration therefor; all logos, symbols, brands, website software and domain addresses, copyrights (whether registered or unregistered) and registrations therefor, and all renewals, renewal rights, reissues, modifications or extensions thereof; and trade secrets, formulae, confidential information and research and development data that are owned by Seller and used in connection with the Business and set forth on Schedule D (collectively, the “Intellectual Property”).

1.2 Seller agrees that it will execute, acknowledge and deliver to Buyer at the Closing such good and sufficient instruments of sale, conveyance, transfer and assignment as shall be effective to vest in the Buyer all right, title and interest in and to the Business Assets, free and clear of all liens, encumbrances, security interests, equities, claims, charges and restrictions whatsoever.

2.	PURCHASE PRICE FOR BUSINESS ASSETS

2.1 Purchase Price - Business Assets. Subject to terms of this Section, the purchase price for the Business Assets shall be an aggregate of up to $6,000,000 (the “Purchase Price”), payable as follows:

Three million dollars ($3,000,000) in cash at Closing (the “Closing Payment”).

A secured promissory note (the “Note”) in the principal amount of two million dollars ($2,000,000) (the “Deferred Payment”), in substantially the form attached hereto as Exhibit 2, delivered at Closing.

Up to one million dollars ($1,000,000) in cash, thirteen (13) months after Closing (the “Risk Share Payment”), payable as set forth in Section 2.2.

2.2 Calculation of Risk Share Payment. The Risk Share Payment referred to in Section 2.1(C) shall be calculated using the net total sales of NASM Products by EZIP to PineStar Technology, Inc. (“PineStar”) in the first twelve (12) months after the Closing (“EZIP PineStar Net Total Sales”) and a figure equal to the actual sales made by Seller to PineStar between November 1, 2007 and April 30, 2008, multiplied by two (2) (the “PineStar Quota”). If the EZIP PineStar Net Total Sales remains at or exceeds the PineStar Quota, the Risk Share Payment will be one million dollars ($1,000,000). Should the EZIP PineStar Net Total Sales be less than the Pine Star Quota, the amount due to Seller will decrease proportionately. Thus, for the purpose of example only, should the EZIP PineStar Net Total Sales amount to fifty percent (50%) of the PineStar Quota, then the amount owed to Seller would be 50% of one million dollars, or five hundred thousand dollars ($500,000). The term NASM Products shall mean those products acquired by EZIP pursuant to this Agreement, or like or similar products produced by EZIP.

In the event that EZIP voluntarily ceases doing business with PineStar during the first 12 months after Closing, or in the event that EZIP sells the Business, in whole or in part, during that period, the Risk Share Payment will be one million dollars ($1,000,000) and shall be due immediately upon such events.

EZIP will use its best efforts to continue to operate the Business for the first twelve (12) months following the Closing.

EZIP shall provide Seller with a quarterly report of the net sales report by EZIP to PineStar of the NASM Products and similar products and NASM shall have the right to audit the net sales at any time at its own cost and expense.

2.3 Purchase Price Adjustment. The Purchase Price will be adjusted to reflect changes in the materials inventory balances. As of August 13, 2008, the materials inventory balance was Five hundred and fifty-six thousand dollars ($556,000) (“Target Inventory Balance”). The purchase price adjustment will be made from the Deferred Payment. In the event that the actual inventory balance at Closing is more than [Fifty-five thousand dollars ($55,000)] less than the Target Inventory Balance, then the Deferred Payment will be decreased in the same amount as such deficit below $501,000.

2.4 Allocation of Purchase Price. Buyer’s third-party allocation of the Purchase Price among the Business Assets will be provided to Seller as soon as possible, but in no event later than November 30, 2008. Such allocation shall be adopted for all purposes related to the sale of the Business Assets hereunder, and Seller and Buyer agree not to file a tax return or otherwise take a position for tax purposes, or otherwise, inconsistent with such allocation.

3.	ASSUMPTION OF LIABILITIES

3.1 Buyer's Assumption of Liabilities. As further consideration for the purchase of the Business Assets, and notwithstanding any other provision hereof to the contrary, at the Closing, Buyer shall assume all Contract Liabilities which arise or become due after the Closing, with respect to or arising under the Customer Accounts and Distributor Contracts listed in Schedule B.

3.2 Seller's Retention of Certain Liabilities. Except for those specific Contract Liabilities referred to in Paragraph 3.1 above, Buyer shall assume no liabilities of Seller with respect to the Business, or related to the Business Assets acquired hereunder including, without limitation, any chargebacks, discounts, credits or other allowances relating to or arising from the Accounts Receivable and the Seller's operation of the Business prior to the Closing Date.

If a party hereto seeks indemnification under this Section 10, such party (the “Indemnified Party”) shall promptly give written notice to the other party (the “Indemnifying Party”) after receiving written notice of any action, lawsuit, proceeding, investigation, or other claim against it (if by a third party) or discovering the Liability, obligation, or facts giving rise to such claim for indemnification, describing the claim, the amount thereof (if known and quantifiable), and the basis thereof; provided that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder except to the extent such failure shall have prejudiced the Indemnifying Party. In that regard, if any action, lawsuit, proceeding, investigation or other claim shall be brought or asserted by any third party which, if adversely determined, would entitle the Indemnified Party to indemnity pursuant to this Section 10, the Indemnified Party shall promptly notify the Indemnifying Party of the same in writing, specifying in detail the basis of such claim and the facts pertaining thereto and the Indemnifying Party shall be entitled to participate in the defense of such action, lawsuit, proceeding, investigation, or other claim giving rise to the Indemnified Party’s claim for indemnification at the Indemnifying Party’s expense and option (subject to the limitations set forth below) shall be entitled to control and appoint lead counsel of such defense with reputable counsel reasonably acceptable to the Indemnified Party; provided that, as a condition precedent to the Indemnifying Party’s right to assume control of such defense, it must first agree in writing to be fully responsible for all Liability relating to such claim and to provide full indemnification to the Indemnified Party for all Liability relating to such claim; and provided further that the Indemnifying Party shall not have the right to assume control of such defense and shall pay the fees and expenses of counsel retained by the Indemnified Party, if the claim which the Indemnifying Party seeks to assume control (each, an “Indemnified Party Controlled Proceeding”) (a) involves a claim to which the Indemnified Party reasonably believes could be detrimental to or injure the Indemnified Party’s reputation, customer or supplier relations or future business prospects, (b) seeks non-monetary relied (except where non-monetary relief is merely incidental to a primary claim or claims of monetary damages), (c) involves criminal allegations, (d) is one in which the Indemnifying Party is also a party and joint representation would be inappropriate or there may be legal defenses available to the Indemnifying Party, or (e) involves a claim which, upon petition by the Indemnified Party, the appropriate court rules that the Indemnifying Party failed or is failing to vigorously prosecute or defend.

If the Indemnifying Party is permitted to assume and control the defense and elects to do so, the Indemnified Party shall have the right to employ counsel separate from counsel employed by the Indemnifying Party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the Indemnified Party shall be at the expense of the Indemnified Party unless the employment thereof has been specifically authorized by the Indemnifying Party in writing.

If the Indemnifying Party shall control the defense of any such claim, the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld) before entering into any settlement of a claim or ceasing to defend such claim unless (a) there is no finding or admission of any violation of law or any violation of the rights of any person or entity and no effect on any other claims that may be made against the Indemnified Party and (b) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party.

10.4 Limitations on Indemnification.

A. Notwithstanding anything contained herein to the contrary, the maximum liability of Seller or Buyer for indemnification under this Section 10 is two million five hundred thousand dollars ($2,500,000).]

B. The provisions for indemnity under Sections 10.1 and 10.2 shall be effective only when the aggregate amount of all Liabilities for which indemnification is sought under Sections 10.1 or 10.2, as the case may be, exceeds fifty thousand dollars ($50,000), provided, however, that in the event the Liabilities exceed such amount, indemnification shall be made with respect to all Liabilities.

C. No Indemnifying Party shall be liable to any Indemnified Party with respect to claims referred to in Sections 10.1 or 10.2 if such Indemnifying Party does not receive written notice of such claims within the Limitation Date.

10.5 Survival of Representations and Warranties; Indemnity Obligations. The representations and warranties of the parties hereto, and all indemnity obligations set forth in this Section 10, contained in this Agreement shall survive the termination of this Agreement or the Closing for a period of three (3) years following the date of the Closing Date (the “Limitation Date”); provided, however, that the representations and warranties set forth in Sections 4.2A, 4.2B, 4.2D, 4.3A, 4.3B and 4.3D shall survive indefinitely; provided, further, that such obligations to indemnify shall not terminate with respect to any matter as to which the Indemnified Party shall have, before the expiration of the applicable period, previously made a claim by delivering a notice of such claim to the indemnifying party.
