At the Effective Time, each issued and outstanding share of PAS Capital Stock (other than shares to be canceled pursuant to Section 2.05(a) hereof and shares, if any, held by Persons who have not voted such shares in favor of the Merger and with respect to which such Person is entitled to exercise appraisal rights in accordance with section 262 of the Delaware Law ("Dissenting Shares")) shall be converted into the right to receive, without any action on the part of the holders thereof, the consideration as set forth in this Agreement. (c) DISSENTERS' RIGHTS. Any Dissenting Shares shall not be converted as described in subsection (b) above but instead shall be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to Delaware 7 Law. If after the Effective Time any Dissenting Shares shall lose their status as Dissenting Shares, then as of the occurrence of the event which causes the loss of such status, such shares shall be converted into the right to receive the Aggregate Initial USSC Stock in accordance with this Article II. (d) FRACTIONAL SHARES. In calculating the Aggregate Initial USSC Stock, no fractional shares of USSC Common Stock shall be issued, but in lieu thereof each holder of shares of PAS Capital Stock who would otherwise be entitled to receive a fraction of a share of USSC Common Stock shall be entitled to receive from USSC an amount of cash equal to the Closing Price multiplied by the fraction of a share of USSC Common Stock to which such holder would otherwise be entitled. The fractional share interests of each PAS shareholder shall be aggregated, so that no PAS shareholder shall receive cash in an amount greater than the value of one full share of USSC Common Stock. (e) INITIAL CONSIDERATION. Subject to Section 2.05(c), the number of shares of USSC Common Stock which shall be issued and delivered at the Effective Time to a holder of any shares of PAS Capital Stock (other than as provided in Section 2.05(a)) immediately prior to the Effective Time shall be that number which results from multiplying (x) the Aggregate Initial USSC Stock (as defined below), by (y) such holder's Ownership Percentage (as defined below). (i) The Aggregate Initial USSC Stock is that number of shares of USSC Common Stock which equals the result from dividing (A) Seventy Five Million Dollars ($75,000,000), minus the amount by which the cash reflected on the balance sheet contained in the Final Interim Period Unaudited Financial Statements, net of all outstanding loans and other indebtedness for money borrowed ("Net Cash Closing Amount"), is less than Twelve Million Seven Hundred Fifty Thousand Dollars ($12,750,000) (which amount shall be reduced subsequent to August 1, l997 at a pro rated rate of Seven Hundred and Fifty Thousand Dollars ($750,000) per month) , by (B) the Closing Price. The Net Cash Closing Amount shall include, without limitation, cash received upon exercise of the PAS Options on or prior to the Effective Date. Payment by PAS prior to the Effective Date of up to One Million Dollars ($1,000,000) of Professional Fees shall not be deemed to reduce the aforesaid Net Cash Closing Amount. (ii) A holder's Ownership Percentage is that fraction the numerator of which is such holder's total PAS Common Stock Equivalents (as defined below) calculated as of the Effective Time and the denominator of which is the Aggregate PAS Common Stock Equivalents (as defined below) calculated as of the Effective Time. A certificate showing each holder's Ownership Percentage shall be available upon request by such holder from PAS following the Effective Time. (iii) A holder's total PAS Common Stock Equivalents are the aggregate number of shares of PAS Common Stock held by such holder immediately prior to the Effective Time plus the aggregate number of shares of PAS Common Stock into which the aggregate number of shares of PAS Preferred Stock held by such holder immediately prior to the Effective Time are convertible in accordance with the PAS Amended and Restated Certificate of Incorporation and Bylaws then in effect. 8 (iv) The Aggregate PAS Common Stock Equivalents are: (a) the aggregate number of shares of PAS Common Stock issued and outstanding immediately prior to the Effective Time, plus (b) the aggregate number of shares of PAS Common Stock into which the aggregate number of shares of PAS Preferred Stock issued and outstanding immediately prior to the Effective Time, are convertible at the Effective Time in accordance with the PAS Amended and Restated Certificate of Incorporation and Bylaws as then in effect, plus (c) the number of shares of PAS Common Stock into which the PAS Options outstanding immediately prior to the Effective Time are deemed to convert upon payment of the exercise price at the Closing, as described in Section 2.05(f) below, or, in the event of a cashless exercise, of such PAS Options (in whole or in part). (v) The ratio of the Aggregate Initial USSC Stock to the Aggregate PAS Common Stock Equivalents is the "Exchange Ratio". (f) STOCK OPTIONS. Each outstanding PAS Option shall by virtue of the Merger and without any action on the part of the holders thereof, be converted into the right to receive USSC Common Stock included in the Aggregate Initial USSC Stock payable pursuant to Section 2.05(e) above. Each such PAS Option shall first be deemed to convert into the number of PAS Common Stock Equivalents provided for in Section 2.05(e)(iv) above. The holders of such PAS Options shall then receive shares of USSC Common Stock based on such deemed PAS Common Stock Equivalents, in the same manner as all other holders of PAS Common Stock Equivalents, which shall be paid in the manner described in Section 2.06 (except that references in Section 2.06 to the surrender of the Certificates shall not be applicable).

Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Aggregate Initial USSC Stock to which the holder of PAS Capital Stock is entitled pursuant to Section 2.05 hereof, along with a check representing the value of any fractional shares as determined pursuant to Section 2.05(d) hereof. The Certificate so surrendered shall forthwith be canceled. Until surrendered as contemplated by this Section 2.06, each Certificate shall be deemed at any time after the Effective Time solely to represent the right to receive upon such surrender such whole number of shares of USSC Common Stock and cash as provided by this Article II and the provisions of Delaware Law as of the Effective Time.

The Aggregate USSC Stock payable with respect to achievement of a Milestone as aforesaid is that number of shares of USSC Common Stock ("Aggregate Milestone USSC Stock") which equals the result from dividing (A) the dollar amount of the milestone payment set forth opposite such Milestone on EXHIBIT 2.07 attached hereto (each a "Milestone Dollar Amount" and, collectively, the "Aggregate Milestone Dollar Amount"), by (B) the Closing Price, calculated with reference to the date such Milestone is achieved by USSC, PAS or any of their Affiliates, as the case may be, as of or subsequent to the Effective Date (a "Milestone Achievement Date").

The number of shares of USSC Common Stock which shall be issued and delivered to a Shareholder who receives Aggregate Initial USSC Stock under Section 2.05 above with respect to Earn Out Consideration shall be equal to that number which results from multiplying (x) the Aggregate Earn Out USSC Stock, by (y) such holder's Ownership Percentage.
