Each holder of Affiliated Company Shares who would otherwise have been entitled to receive a fraction of a GraphOn Share pursuant to this Article II shall, in lieu thereof, be issued one whole GraphOn Share. For purposes of determining whether and to what extent a stockholder is entitled to receive a GraphOn Share in lieu of a fractional share pursuant to this Section 2.7, the Affiliated Company Shares held of record by such stockholder and represented by two or more stock certificates of a particular Affiliated Company shall be aggregated. 2.8 Procedure for Exchange. ---------------------- (a) Immediately after the Cortelco Effective Time, CIDCO Effective Time, and SLL Effective Time, as applicable, GraphOn shall deposit with American Stock Transfer & Trust Company, or such other exchange agent selected by GraphOn and reasonably acceptable to the Affiliated Companies, (the "Exchange Agent") for the benefit of the holders of Affiliated Company Shares, (i) certificates representing the GraphOn Shares that make up the Merger Shares, calculated as follows: the sum of (x) the product of the Cortelco Conversion Ratio multiplied by the number of Cortelco Shares (other than any Dissenting Shares) issued and outstanding immediately prior to the Cortelco Effective Time, (y) the product of the CIDCO Conversion Ratio multiplied by the number of CIDCO Shares (other than any Dissenting Shares) issued and outstanding immediately prior to the CIDCO Effective Time, and (z) the product of the SLL Conversion Ratio multiplied by the number of SLL Shares (other than any Dissenting Shares) issued and outstanding immediately prior to 15 the SLL Effective Time, and, (ii) any dividends or other distributions with respect to GraphOn Shares with a record date at or after the Cortelco Effective Time, CIDCO Effective Time, and SLL Effective Time, as applicable, (such certificates for GraphOn Shares, together with the amount of any dividends or other distributions payable with respect thereto, are referred to as the "Exchange Fund") in exchange for Affiliated Company Shares outstanding immediately prior to the Cortelco Effective Time, CIDCO Effective Time, and SLL Effective Time, respectively, and upon due surrender of certificates representing the Affiliated Company Shares pursuant to this Article II. (b) Promptly after the Cortelco Effective Date, CIDCO Effective Date, and SLL Effective Date, respectively, GraphOn shall cause the Exchange Agent to mail to each record holder of Affiliated Company Shares (other than Dissenting Shares) (i) a letter of transmittal specifying that delivery shall be effected, and risk of loss and title to the certificates representing Affiliated Company Shares shall pass, only upon delivery of such certificates (or affidavits of loss in lieu thereof) to the Exchange Agent, such letter of transmittal to be in such form and have such other provisions as GraphOn and the Exchange Agent may reasonably agree, and (ii) instructions for use in effecting the surrender of the certificates representing Affiliated Company Shares in exchange for (A) certificates representing GraphOn Shares and (B) any unpaid dividends and other distributions thereon. Upon surrender of a certificate representing Affiliated Company Shares 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 (x) a certificate representing that number of whole GraphOn Shares that such holder is entitled to receive pursuant to this Article II, and (y) a check in the amount (after giving effect to any required tax withholdings) of any unpaid non-stock dividends and any other dividends or other distributions that such holder has the right to receive pursuant to the provisions of this Article II, and the certificate representing the Affiliated Company Shares will be canceled. No interest will be paid or accrued on any amounts payable upon due surrender of the certificates representing Affiliated Company Shares. In the event of a transfer of ownership of Affiliated Company Shares that is not registered in the transfer records of the appropriate Affiliated Company, a certificate representing the proper number of GraphOn Shares, together with a check for any cash to be paid upon due surrender of the certificate representing the Affiliated Company Shares, and any other dividends or distributions in respect thereof may be issued and/or paid to such transferee if the certificate formerly representing such Affiliated Company Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. If any certificate for GraphOn Shares is to be issued in a name other than that in which the certificate surrendered for exchange therefor is registered, it shall be a condition of such exchange that the Person requesting such exchange shall pay any transfer or other taxes required by reason of the issuance of certificates for GraphOn Shares in a name other than that of the registered holder of the certificate surrendered, or shall establish to the satisfaction of GraphOn or the Exchange Agent that such tax has been paid or is not applicable. 16 (c) GraphOn shall not pay any dividend or make any distribution on GraphOn Shares, with a record date at or after the Cortelco Effective Time, CIDCO Effective Time, or SLL Effective Time, to any record holder of Affiliated Company Shares unless and until the holder surrenders for exchange the stock certificate or certificates that formerly represented the holder's Affiliated Company Shares. GraphOn instead shall pay the dividend or make the distribution to the Exchange Agent in trust for the benefit of the holder pending the surrender and exchange. No holder of Affiliated Company Shares shall be entitled to any interest or earnings on the dividend or distribution held in trust by the Exchange Agent pending receipt thereof by the holder upon surrender for exchange of the Affiliated Company Share certificates. (d) In the event any certificate representing Affiliated Company Shares shall have been lost, stolen, or destroyed, upon the making of an affidavit of such fact by the Person claiming such certificate has been lost, stolen, or destroyed, and if required by GraphOn, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such certificate, the Exchange Agent will issue in exchange for such documentation of the lost, stolen, or destroyed certificate, the GraphOn Shares and any unpaid dividends or other distributions in respect thereof. (e) GraphOn may terminate the Exchange Fund and cause the Exchange Agent to return any GraphOn Shares and dividends and distributions thereon remaining unclaimed 180 days after the Closing Date, and thereafter each remaining record holder of Affiliated Company Shares who has not surrendered for exchange the certificates representing the Affiliated Company Shares shall be entitled to look to GraphOn (subject to abandoned property, escheat, and other similar Laws) as a general creditor thereof with respect to the GraphOn Shares and dividends and distributions thereon to which the holder is entitled upon surrendering for exchange the stock certificate or certificates that formerly represented the holder's Affiliated Company Shares. Notwithstanding the foregoing, none of GraphOn, the Cortelco Surviving Corporation, CIDCO Surviving Corporation, SLL Surviving Corporation, or the Exchange Agent shall be liable to any former holder of Affiliated Company Shares for any amounts properly delivered to a public official pursuant to applicable abandoned property, escheat, or similar Laws. (f) GraphOn shall pay all fees, expenses, and other charges of the Exchange Agent. 2.9 Closing of Stock Transfer Records.

(g) The consummation of the transactions contemplated by this Agreement will not accelerate the time of vesting or payment, or increase the amount, of the compensation or benefits to be paid or provided to any present or former officer or employee of GraphOn. No Contract or Employee Benefit Plan provides for any "excess parachute payment," within the meaning of Section 4999 of the Code, upon or in connection with the consummation of the transactions contemplated by this Agreement. (h) GraphOn has not been liable at any time for contributions to any Employee Benefit Plan that is or was subject to Title IV of ERISA.

With respect to each Employee Benefit Plan, subject to only normal retrospective adjustments in the ordinary course, all insurance premiums, including premiums to the PBGC, have been paid in full for policy years or other applicable policy periods ending on or prior to the date hereof. There exists no "accumulated funding deficiency" within the meaning of Section 302 of ERISA and Section 412 of the Code, with respect to any Employee Benefit Plan, regardless of whether such deficiency has been waived. 46 (j) GraphOn does not have, and the consummation of the transactions contemplated by this Agreement will not result in, any Liability for (a) any minimum funding contribution required under Section 302(c)(11) of ERISA or Section 412(c)(11) of the Code, (b) any payment required under Section 302(e) of ERISA or Section 412(m) of the Code, (c) any lien imposed under Section 302(f) of ERISA or Section 412(n) of the Code, (d) any excise tax imposed with respect to an accumulated funding deficiency under Section 4971 of the Code, (e) the termination of or withdrawal from any plan under Sections 4062, 4063, or 4064 of ERISA, or (f) the withdrawal from any multi-employer plan under Section 4201 of ERISA.

GraphOn has not incurred and does not expect to incur any withdrawal Liability (either as a contributing employer or as part of a controlled group which includes a contributing employer) to any multiemployer plan, in connection with any complete or partial withdrawal from such plan occurring on or before the Closing Date or as a result of the transactions contemplated under this Agreement. (l) No Employee Benefit Plan provides medical, life or other welfare benefits (whether or not insured), with respect to current or former employees after retirement or other termination of service (other than coverage mandated by applicable Law). With respect to any Contract or arrangement with an insurance company providing funding under any Employee Benefit Plan, there is no Liability for any retroactive rate adjustment. GraphOn has the right to amend or terminate its participation with respect to each Employee Benefit Plan. Each Employee Benefit Plan that is a "group health plan," within the meaning of Section 5000 of the Code has been operated in compliance with Section 4980B of the Code or Sections 601 through 608 of ERISA and the secondary payor requirements of Section 1862(b) of the Social Security Act.
