1.             DEFINITIONS.  As used herein, the following terms shall have the following respective meanings:

(a)   “Exercise Period” shall mean the period commencing with the date hereof and ending five years from the date hereof, unless sooner terminated as provided below.

(b)   “Exercise Price” shall mean $ .91 per share, subject to adjustment pursuant to Section 5 below.

(c)   “Exercise Shares” shall mean the shares of the Company’s Common Stock issuable upon exercise of this Warrant.

2.             EXERCISE OF WARRANT.

2.1          Restrictions on Exercise.

The Exercise Shares shall be exercisable as follows:

(a)   one-third of the Exercise Shares shall be exercisable on the effective date of transfer of all intellectual property assets of the Holder’s PurePoint technology to the Company;

(b)   one-third of the Exercise Shares shall be exercisable upon implementation by Holder of marketing initiatives agreed upon by the Holder and the Company for the sale by Holder of the Company’s products; and

(c)   up to one-third of the Exercise Shares shall be exercisable upon the Company recognizing $15 million in net revenue from the sale of the Company’s products to Holder, with 580,973 shares being exercisable upon recognizing $10 million in net revenues, and the remaining 290,486 shares being exercisable on a prorata basis for net revenue recognized above $10 million up to $15 million.

Notwithstanding the foregoing, (i) exercise of this Warrant is subject to approval by the Company’s stockholders of an amendment to the Company’s Certificate of Incorporation to increase the authorized Common Stock thereunder to an aggregate of 100,000,000 shares (the “Certificate Amendment”) and (ii) in the event the merger contemplated by that certain Agreement and Plan of Merger and Reorganization among First Virtual Communications, Inc., FVC Acquisition Corp., and CUseeMe Networks, Inc., dated as of March 22, 2001, is not consummated on or before August 1, 2001, this Warrant shall be null and void.

2.2          Mechanics of Exercise.  Subject to the limitations on exercise set forth in Section 2.1 above, the rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth above (or at such other address as it may designate by notice in writing to the Holder):

(a)   An executed Notice of Exercise in the form attached hereto;

(b)   Payment of the Exercise Price either (i) in cash or by check, or (ii) by cancellation of indebtedness; and

(c)   This Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Exercise Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised.

The person in whose name any certificate or certificates for Exercise Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

2.3          Net Exercise.  Notwithstanding any provisions herein to the contrary, if the fair market value of one share of the Company’s Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:

X = Y (A-B)

A

Where    X =          the number of shares of Common Stock to be issued to the Holder

Y =          the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such calculation)

A =         the fair market value of one share of the Company’s Common Stock (at the date of such calculation)

B =          Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the fair market value of one share of Common Stock shall be equal to the fair market value of one share of Common Stock of the Company as quoted on the Nasdaq National Market on the date of such calculation.

3.             COVENANTS OF THE COMPANY.

3.1          Covenants as to Exercise Shares.  The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof.  Subject to approval of the Certificate Amendment by the Company’s stockholders as described in Section 2.1 above, the  Company further covenants and agrees that the Company will at all times subsequent to stockholder approval of the Certificate Amendment during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant.  If at any time during the Exercise Period the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

3.2          No Impairment.  Except and to the extent as waived or consented to by the Holder, the Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment.

3.3          Notices of Record Date.  In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarters) or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution.

4.             REPRESENTATIONS OF HOLDER.

4.1          Acquisition of Warrant for Personal Account.  The Holder represents and warrants that it is acquiring the Warrant solely for its account for investment and not with a view to or for sale or distribution of said Warrant or any part thereof.  The Holder also represents that the entire legal and beneficial interests of the Warrant and Exercise Shares the Holder is acquiring is being acquired for, and will be held for, its account only.

4.2          Securities Are Not Registered.

(a)           The Holder understands that the Warrant and the Exercise Shares have not been registered under the Securities Act of 1933, as amended (the “Act”).  The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities.  The Holder has no such present intention.

(b)           The Holder recognizes that the Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available.  The Holder recognizes that the Company has no obligation to register the Warrant or the Exercise Shares of the Company, or to comply with any exemption from such registration.

(c)           The Holder is aware that neither the Warrant nor the Exercise Shares may be sold pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations.  Holder is aware that the conditions for resale set forth in Rule 144 have not been satisfied and that the Company presently has no plans to satisfy these conditions in the foreseeable future.

4.3          Disposition of Warrant and Exercise Shares.

(a)           The Holder further agrees not to make any disposition of all or any part of the Warrant or Exercise Shares in any event unless and until:

(i)            The Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the proposed disposition; or

(ii)           There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with said registration statement; or

(iii)         The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the effect that such disposition will not require registration of such Warrant or Exercise Shares under the Act or any applicable state securities laws.

(b)           The Holder understands and agrees that all certificates evidencing the shares to be issued to the Holder may bear the following legend:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”).  THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

5.             ADJUSTMENT OF EXERCISE PRICE.  In the event of changes in the outstanding Common Stock of the Company by reason of stock dividends, split-ups, recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of shares available under the Warrant in the aggregate and the Exercise Price shall be correspondingly adjusted to give the Holder of the Warrant, on exercise for the same aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had the Warrant been exercised prior to the event and had the Holder continued to hold such shares until after the event requiring adjustment; provided, however, that such adjustment shall not be made with respect to, and this Warrant shall terminate if not exercised prior to, the events set forth in Section 7 below.  The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant.

6.             FRACTIONAL SHARES.  No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto.  All Exercise Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share.  If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of an Exercise Share by such fraction.

7.             EARLY TERMINATION.  In the event of, at any time during the Exercise Period, any capital reorganization, or any reclassification of the capital stock of the Company (other than a change in par value or from par value to no par value or no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), or the consolidation or merger of the Company with or into another corporation (other than a merger solely to effect a reincorporation of the Company into another state), or the sale or other disposition of all or substantially all the properties and assets of the Company in its entirety to any other person, the Company shall provide to the Holder twenty (20) days advance written notice of such public offering, reorganization, reclassification, consolidation, merger or sale or other disposition of the Company’s assets, and this Warrant shall terminate unless exercised prior to the date such public offering is closed or the occurrence of such reorganization, reclassification, consolidation, merger or sale or other disposition of the Company’s assets.

8.             MARKET STAND-OFF AGREEMENT.  Holder shall not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by Holder, for a period of time specified by the managing underwriter(s) (not to exceed one hundred eighty (180 days) following the effective date of a registration statement of the Company filed under the Securities Act of 1933.  Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company and/or the managing underwriter(s) which are consistent with the foregoing or which are necessary to give further effect thereto.  In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to such Common Stock (or other securities) until the end of such period.  The underwriters of the Company’s stock are intended third party beneficiaries of this Section 8 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

9.             NO STOCKHOLDER RIGHTS.  This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

10.          TRANSFER OF WARRANT.  Subject to applicable laws and the restriction on transfer set forth on the first page of this Warrant, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto, to any affiliate of Holder.  The transferee shall sign an investment letter in form and substance satisfactory to the Company.

11.          LOST, STOLEN, MUTILATED OR DESTROYED WARRANT.  If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed.  Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

12.          NOTICES, ETC.  All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.  All communications shall be sent to the Company and to Holder at their respective addresses listed on the first page of this Warrant or at such other address as the Company or Holder may designate by ten (10) days advance written notice to the other parties hereto.

13.          ACCEPTANCE.  Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

14.          GOVERNING LAW.  This Warrant and all rights, obligations and liabilities hereunder shall be governed by the laws of the State of California.
