      1.6 Exchange of Shares.

	(a) Prior to the Effective Time, CyberCash shall appoint the Exchange Agent to effect the exchange for the Merger Shares of certificates that, immediately prior to the Effective Time, represented Network 1 Shares converted into Merger Shares pursuant to Section 1.5 (“Certificates”). On the Closing Date, CyberCash shall deliver to the Exchange Agent, in trust for the benefit of holders of Network 1 Shares, a stock certificate (issued in the name of the Exchange Agent or its nominee) representing the Merger Shares, as described in Section 1.5. No later than ten (10) business days following the Effective Time, CyberCash shall cause the Exchange Agent to send a notice and a transmittal form to each holder of a Certificate advising such holder of the effectiveness of the Merger and the procedure for surrendering to the Exchange Agent such Certificate in exchange for the Merger Shares issuable pursuant to Section 1.5. Each holder of a Certificate, upon proper surrender thereof to the Exchange Agent in accordance with the instructions in such notice, shall be entitled to receive in exchange therefor (subject to any taxes required to be withheld) the Merger Shares issuable pursuant to Section 1.5. Until properly surrendered, each such Certificate shall be deemed for all purposes to evidence only the right to receive the Merger Shares issuable pursuant to Section 1.5. Holders of Certificates shall not be entitled to receive certificates for the Merger Shares to which they would otherwise be entitled until such Certificates are properly surrendered.
	(b) If any Merger Shares are to be issued in the name of a person other than the person in whose name the Certificate surrendered in exchange therefor is registered, it shall be a condition to the issuance of such Merger Shares that: (i) the Certificate so surrendered shall be properly assigned, endorsed or accompanied by appropriate stock powers; (ii) such transfer shall otherwise be proper; and (iii) the person requesting such transfer shall pay to the Exchange Agent any transfer or other taxes payable by reason of the foregoing or establish to the satisfaction of the Exchange Agent that such taxes have been paid or are not required to be paid. Notwithstanding the foregoing, neither the Exchange Agent nor any Party shall be liable to a

-10-

	holder of Network 1 Shares for any Merger Shares issuable to such holder pursuant to Section 1.5 that are delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.
	(c) In the event any Certificate shall have been lost, stolen or destroyed, only upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, shall CyberCash issue in exchange for such lost, stolen or destroyed Certificate the Merger Shares issuable in exchange therefor pursuant to Section 1.5. The board of directors of CyberCash may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to submit to CyberCash an affidavit and to give to CyberCash an indemnity against any claim that may be made against CyberCash with respect to the Certificate alleged to have been lost, stolen or destroyed. In addition, a holder of such lost, stolen or destroyed Certificate may be required by the Exchange Agent to post a bond in connection therewith.
	(d) Promptly following the date that is one year from the Closing Date, the Exchange Agent shall return to CyberCash all Merger Shares in its possession, and the Exchange Agent’s duties shall terminate. Thereafter, each holder of a Certificate may surrender such Certificate to CyberCash and, subject to applicable abandoned property, escheat and similar laws, receive in exchange therefor the Merger Shares issuable with respect thereto pursuant to Section 1.5.

      1.7 Dividends.

      No dividends or other distributions that are payable to the holders of record of CyberCash Common Stock as of a date on or after the Closing Date shall be paid to former Network 1 Shareholders entitled by reason of the Merger to receive Merger Shares until such holders surrender their Certificates in accordance with Section 1.6. Upon such surrender, CyberCash shall pay or deliver to the persons in whose name the certificates representing such Merger Shares are issued any dividends or other distributions that are payable to the holders of record of CyberCash Common Stock as of a date on or after the Closing Date and that were paid or delivered between the Effective Time and the time of such surrender; provided, however, that no such person shall be entitled to receive any interest on such dividends or other distributions.

      1.8 Fractional Shares.

      No certificates or scrip representing fractional Merger Shares shall be issued to former Network 1 Shareholders upon the surrender for exchange of Certificates, and such former Network 1 Shareholders shall not be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a shareholder of CyberCash with respect to any fractional Merger Shares that would otherwise be issued to such former Network 1 Shareholders. In lieu of any fractional Merger Shares that would otherwise be issued, upon proper surrender of such person's Certificates each former Network 1 Shareholder that would have been entitled to receive (i) a fractional Common Merger Share shall receive a cash payment equal to the CyberCash Share Market Value,

-11-

multiplied by the fraction of a share that such Network 1 Shareholder would otherwise be entitled to receive; and (ii) a fractional Preferred Merger Share shall receive a cash payment equal to ten times the CyberCash Share Market Value, multiplied by the fraction of a share that such Network 1 Shareholder would otherwise be entitled to receive.

      1.9 Options; Warrants and Restricted Stock.

	(a) At the Effective Time, each option (each, an “Option,” and collectively the “Options”) to purchase Network 1 Common Stock issued by Network 1 pursuant to the Network 1 Financial Corporation 1999 Stock Option and Incentive Plan (the "Network 1 Stock Option Plan”) or otherwise, to the extent outstanding and not exercised immediately prior to the Effective Time, shall become and represent an option to acquire, such number of shares of CyberCash Common Stock as is equal to the number of shares of Network 1 Common Stock subject to the unexercised portion of such Option immediately prior to the Effective Time multiplied by the Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the next lower whole number). The exercise price per share of each such assumed Option shall be equal to the exercise price of such Option immediately prior to the Effective Time, divided by the Conversion Ratio (with any fraction of a cent resulting from such division to be rounded up to the next higher whole cent). Except as provided in Section 1.9, all other provisions of each Option in effect immediately prior to the Effective Time shall otherwise remain unchanged. Each Option awarded under the Network 1 Stock Option Plan that is assumed by CyberCash shall automatically and without any action on the part of any Party or any holder thereof have the vesting rights set forth in Section 1.9 of the letter to be delivered by the Parties as of the date hereof (the “Disclosure Letter”).
	(b) At the Effective Time, each warrant to purchase Network 1 Common Stock issued by Network 1, (each, a “Common Warrant” and collectively the "Warrants”), to the extent outstanding and not exercised immediately prior to the Effective Time, shall become and represent a warrant to acquire, on the same terms and conditions as were applicable under such Common Warrant immediately prior to the Effective Time, such number of shares of CyberCash Common Stock as is equal to the number of shares of Network 1 Common Stock subject to the unexercised portion of such Common Warrant immediately prior to the Effective Time multiplied by the Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the next lower whole number). The exercise price per share of each such assumed Common Warrant shall be equal to the exercise price of such Common Warrant immediately prior to the Effective Time, divided by the Conversion Ratio (with any fraction of a cent resulting from such division to be rounded up to the next higher whole cent). The term and all of the other provisions of each Common Warrant in effect immediately prior to the Effective Time shall otherwise remain unchanged.
	(c) As soon as practicable after the Effective Time, CyberCash or the Surviving Corporation shall deliver to the holders of Options and Warrants appropriate notices setting forth such holders’ rights pursuant to such Options and Warrants, as amended by this Section 1.9. The agreements evidencing the Options and Warrants shall continue in effect on the same terms and conditions (subject to the amendments provided for in this Section 1.9 and in Section 1.9 of the Disclosure Letter and such notice) and CyberCash shall enter into an

-12-

	amendment to the applicable option or warrant agreements to such effect. Network 1 shall obtain, prior to the Closing, the consent (in such form as approved by CyberCash) from each holder of a Warrant or an Option to the assumption of such Warrant or Option, as the case may be, and to any revisions to the option or warrant agreement associated therewith pursuant to this Section 1.9 and Section 1.9 of the Disclosure Letter.
	(d) CyberCash shall take all corporate action necessary to reserve for issuance a sufficient number of shares of CyberCash Common Stock for delivery upon exercise of the Options and Warrants issued or exchanged, as the case may be, in accordance with this Section 1.9. Promptly after the Closing Date, CyberCash shall file a registration statement on Form S-8 (or any successor or other appropriate forms) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the shares of CyberCash Common Stock subject to the Options and shall use its best efforts to maintain the effectiveness of such registration statement (and maintain the current status of the prospectus or prospectuses contained therein) for so long as the Options remain outstanding.
	(e) All Network 1 Shares which are subject to restrictions (the “Network 1 Restricted Stock”) shall be converted into shares of CyberCash Common Stock pursuant to the terms of Section 1.5 hereof, and on and after the Effective Date such CyberCash Common Stock shall continue to be subject to all terms, conditions and restrictions applicable to Network 1 Restricted Stock prior to the Effective Date.

-13-

      1.10 Articles of Incorporation.

      At the Effective Time, the Articles of Incorporation of Merger Sub, as in effect immediately prior the Effective Time, shall be the Articles of Incorporation of the Surviving Corporation until thereafter amended as provided by VSCA; provided, however, that Section 1 of the Articles of Incorporation of the Surviving Corporation shall be amended to read as follows: “The name of the Corporation is NETWORK 1 FINANCIAL CORPORATION.”

Section 1.1502.6 (or any similar provision of state, local, or foreign law), as a transferee or successor, by contract, or otherwise.
