                           Purchase and Sale Agreement

1. ASSIGNMENT. PRESTIGE CAPITAL CORPORATION ("Prestige") hereby buys and NORTH
ATLANTIC LABORATORIES' INC.

("Seller") hereby sells, transfers and assigns all of Seller's right, title and
interest in and to those specific accounts receivable owing to Seller as set
forth on the assignment forms provided by Prestige (the "Assignments") together
with all rights of action accrued or to accrue thereon, including without
limitation, full power to collect, sue for, compromise, assign or in any other
manner enforce collection thereof in Prestige's name or otherwise. (All of
Seller's accounts receivable and contract rights which are presently or at any
time hereafter assigned by Seller, and accepted by Prestige, are collectively
referred to as the "Accounts".)

2. DISCOUNT. Prestige's purchase of the Accounts from Seller is at a discount
fee of ELEVEN percent (11%) from the face value of each Account.

3. RESERVE. Upon Prestige's receipt and acceptance of each Assignment, Prestige

Accounts therein described (the "Down Payment"). Prestige will hold in reserve
the difference between the Purchase Price (hereinafter defined) and the Down

forth on the applicable Assignment have been collected in good funds, charged
back and/or deemed collected by Prestige due to an account debtor's (hereinafter

shall mean the net face value of Accounts, less: Prestige's discount fee
described in paragraph 2 above; returns, credits, allowances and discounts on
the shortest or, at Prestige's option, on alternative terms of sale offered by
Seller to account debtors; and less all other sums charged or chargeable to
Seller's account.

          receivable and/or its inventory without the prior written consent of
          Prestige;

     (j)  Seller will not change or modify the terms of the Accounts with any
          account debtor unless Prestige first consents in writing;

     (k)  Seller will notify Prestige in writing in advance of: any change in

except if payments are not received due to the "Insolvency" of an account debtor

arising from or relating to the sale of goods or rendition of services or
arising from or relating to any other transaction or occurrence, then in any
such event Prestige shall have the right to chargeback such Account to Seller.

Seller acknowledges that all amounts chargeable to Seller's account under this
Agreement shall be payable by Seller on demand.

8. NOTICE OF DISPUTE. Seller must immediately notify Prestige of any disputes
between any account debtor and Seller.

9. SETTLEMENT OF DISPUTE. Prestige may, at its option, settle any dispute with
any account debtor Such settlement does not relieve Seller of any of its
obligations under this Agreement.

account debtors relative to the Accounts is the sole property of Prestige. Any
interference by Seller with this payment will result in civil and/or criminal

statements (in form and substance satisfactory to Prestige and its counsel).

13. HOLD IN TRUST. Seller will hold in trust and safekeeping, as the property of
Prestige and immediately turn over to Prestige, the identical check or other
form of payment received by Seller if payment on the Accounts comes into
Seller's possession. Should Seller come into possession of a check comprising
payments owing to both Seller and Prestige, Seller shall turn over said check to
Prestige. Thereafter, Prestige will refund Seller's portion, if any, to Seller.

14. FINANCIAL RECORDS. Seller will furnish to Prestige financial statements and
such other information as is, from time to time, requested by Prestige.

15. BOOK ENTRY. Seller will immediately, upon the sale of the Accounts, make the
proper entry on its books and records disclosing the absolute sale of the
Accounts to Prestige.
