                       FIRST VIRTUAL COMMUNICATIONS, INC.

                      WARRANT TO PURCHASE 300,000 SHARES OF
                    COMMON STOCK, PAR VALUE $0.001 PER SHARE

                  FOR VALUE RECEIVED, Ralph Ungermann ("Warrantholder"), is
entitled to purchase, subject to the provisions of this Warrant, from First
Virtual Communications, Inc., a Delaware corporation ("Company"), at any time
after April 13, 2003 and not later than 5:00 P.M., Eastern time, on the
Expiration Date (as defined above), at an exercise price per share equal to
$0.38, which is 125% of the average closing bid prices per share of the
Company's Common Stock, as reported on The Nasdaq SmallCap Market, during the
period of five (5) days prior to the "Effective Date" of the Private Equity Line
Financing Agreement (the "Equity Line Agreement"), executed by Warrantholder and
Company and dated April 14, 2003 (the exercise price per share in effect being
herein called the "Warrant Price"), 300,000 shares ("Warrant Shares") of the
Company's Common Stock, par value $0.001 per share ("Common Stock"). The number
of Warrant Shares purchasable upon exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time as described herein.

         SECTION 1.        Registration. The Company shall maintain books for
the transfer and registration of the Warrant. Upon the initial issuance of this
Warrant, the Company shall issue and register the Warrant in the name of the
Warrantholder.

         SECTION 2.        Transfers. As provided herein, this Warrant may be
transferred only pursuant to a registration statement filed under the Securities
Act of 1933, as amended ("Securities Act"), or an exemption from such
registration. Subject to such restrictions, the Company shall transfer this
Warrant from time to time upon the books to be maintained by the Company for
that purpose, upon surrender thereof for transfer properly endorsed or
accompanied by appropriate instructions for transfer and such other documents as
may be reasonably required by the Company, including, if required by the
Company, an opinion of its counsel to the effect that such transfer is exempt
from the registration requirements of the Securities Act of 1933, to

                                       1
<PAGE>

establish that such transfer is being made in accordance with the terms hereof,
and a new Warrant shall be issued to the transferee and the surrendered Warrant
shall be canceled by the Company.

         SECTION 3.        Exercise of Warrant. Subject to the provisions
hereof, the Warrantholder may exercise this Warrant in whole or in part at any
time upon surrender of the Warrant, together with delivery of the duly executed
Warrant exercise form attached hereto as Appendix A (the "Exercise Agreement")
and payment by cash, certified check or wire transfer of funds for the aggregate
Warrant Price for that number of Warrant Shares then being purchased, to the
Company during normal business hours on any business day at the Company's
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the holder hereof). The Warrant Shares so purchased
shall be deemed to be issued to the holder hereof or such holder's designee, as
the record owner of such shares, as of the close of business on the date on
which this Warrant shall have been surrendered (or evidence of loss, theft or
destruction thereof and security or indemnity satisfactory to the Company), the
Warrant Price shall have been paid and the completed Exercise Agreement shall
have been delivered. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
three (3) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be requested by
the holder hereof and shall be registered in the name of such holder or such
other name as shall be designated by such holder. If this Warrant shall have
been exercised only in part, then, unless this Warrant has expired, the Company
shall, at its expense, at the time of delivery of such certificates, deliver to
the holder a new Warrant representing the number of shares with respect to which
this Warrant shall not then have been exercised. As used herein, "business day"
means a day, other than a Saturday or Sunday, on which banks in New York City
are open for the general transaction of business. Each exercise hereof shall
constitute the re-affirmation by the Warrantholder that the representations and
warranties with respect to the Warrant Shares contained in Section 4 below are
true and correct in all respects with respect to the Warrantholder as of the
time of such exercise.

         SECTION 4.        Compliance with the Securities Act of 1933;
Investment Representations.

                  (a)      The Company may cause the legend set forth on the
first page of this Warrant to be set forth on each Warrant or similar legend on
any security issued or issuable upon exercise of this Warrant, unless counsel
for the Company is of the opinion as to any such security that such legend is
unnecessary.

                  (b)      The Investor understands that: (i) the offering and
sale of this Warrant and the Warrant Shares purchasable upon exercise of this
Warrant is intended to be exempt from the registration requirements of the
Securities Act; (ii) the offer and sale of this Warrant and the Warrant Shares
purchasable upon exercise of this Warrant has not been registered under the
Securities Act or any other applicable securities laws and such securities may
be resold only if registered under the Securities Act and any other applicable
securities laws or if an exemption from such registration requirements is
available; and (iii) the Company is not required to register any resale of this
Warrants or the Warrant Shares under the Securities Act or any other applicable
securities laws.

                  (c)      The Investor represents that the Warrant and the
Warrant Shares purchasable upon exercise of this Warrant are being acquired for
his own account and not with a view to, or for sale in connection with, any
distribution thereof in violation of the Securities Act or any other securities
laws that may be applicable.

                  (d)      The Investor represents that the Investor (i) is an
"accredited investor" as that term is defined in Rule 501(a) of Regulation D
under the Securities Act, (ii) has sufficient knowledge and experience in
financial and business matters so as to be capable of evaluating the merits and
risks of his acquisition of the Warrant and investment in the Warrant Shares and
is capable of bearing the economic risks of such investment, including a
complete loss of his investment in any Warrant Shares purchasable upon exercise
of this Warrant; (iii) believes that his acquisition of the Warrant and
investment in the Warrant Shares purchasable upon exercise of this Warrant is
suitable for him based upon his objectives and financial needs, and the Investor
has adequate means for providing for his current financial needs and business
contingencies and has no present need for liquidity of any investment with
respect to this Warrant or any Warrant Shares purchasable upon exercise of this
Warrant; and (iv) has not purchased, sold or entered into any put option, short
position or similar arrangement with respect to any Warrant Shares purchasable
upon exercise of this Warrant.

                  (e)      The Investor acknowledges that no oral or written
statements or representations have been made to the Investor by or on behalf of
the Company in connection with the offering and sale of this Warrant or any
Warrant Shares purchasable upon exercise of this Warrant other than those set
forth in the Company's Annual Report on Form 10-K for the year-ended December
31, 2002, the Company's definitive proxy statement, filed April 12, 2002, and
the Company's other reports and documents filed under Sections 13(a), 13(c), 14
or 15(d) under the Securities Exchange Act of 1934, as amended, or as set forth
herein.

                  (f)      The Investor acknowledges that the Securities Act and
state securities laws restrict the transferability of securities, such as the
Warrant Shares, issued in reliance upon the exemption from the registration
requirements of the Securities Act provided by Section 4(2) thereunder and
applicable state securities laws, and that, unless registered under the
Securities Act or an exemption from registration is available, the Warrant
Shares purchasable upon exercise of this Warrant must be held indefinitely.

                  (g)      The Investor has been furnished with all materials
relating to the business, finances and operations of the Company and materials
relating to the issuance of this Warrant and the Warrant Shares purchasable upon
exercise of this Warrant which have been requested by the Investor. The Investor
has been afforded the opportunity to ask questions of the Company. The Investor
understands that its investment in the Warrant and any Warrant Shares
purchasable upon exercise of this Warrant involves a significant degree of risk.

                  (h)      The Investor shall make all filings with the
Commission required under the Exchange Act, including reports required under
Regulation 13D-G and Section 16 thereunder, within the time periods required
under the Exchange Act, in connection with any purchase of Warrant Shares upon
exercise of this Warrant.

                                       3

         SECTION 5.        Payment of Taxes. The Company will pay any
documentary stamp taxes attributable to the initial issuance of Warrant Shares
issuable upon the exercise of the Warrant; provided, however, that the Company
shall not be required to pay any tax or taxes which may be payable in respect of
any transfer involved in the issuance or delivery of any certificates for
Warrant Shares in a name other than that of the registered holder of this
Warrant in respect of which such shares are issued, and in such case, the
Company shall not be required to issue or deliver any certificate for Warrant
Shares or any Warrant until the person requesting the same has paid to the
Company the amount of such tax or has established to the Company's reasonable
satisfaction that such tax has been paid. The holder shall be responsible for
income taxes due under federal, state or other law, if any such tax is due.

         SECTION 6.        Mutilated or Missing Warrants. In case this Warrant
shall be mutilated, lost, stolen, or destroyed, the Company shall issue in
exchange and substitution of and upon cancellation of the mutilated Warrant, or
in lieu of and substitution for the Warrant lost, stolen or destroyed, a new
Warrant of like tenor and for the purchase of a like number of Warrant Shares,
but only upon receipt of evidence reasonably satisfactory to the Company of such
loss, theft or destruction of the Warrant, and with respect to a lost, stolen or
destroyed Warrant, reasonable indemnity or bond with respect thereto, if
requested by the Company.

         SECTION 7.        Reservation of Common Stock. The Company hereby
represents and warrants that there have been reserved, and the Company shall at
all applicable times keep reserved until issued (if necessary) as contemplated
by this Section 7, out of the authorized and unissued shares of Common Stock,
sufficient shares to provide for the exercise of the rights of purchase
represented by this Warrant. The Company agrees that all Warrant Shares issued
upon due exercise of the Warrant shall be, at the time of delivery of the
certificates for such Warrant Shares, duly authorized, validly issued, fully
paid and non-assessable shares of Common Stock of the Company.

         SECTION 8.        Adjustments. Subject and pursuant to the provisions
of this Section 8, the Warrant Price and number of Warrant Shares subject to
this Warrant shall be subject to adjustment from time to time as set forth
hereinafter.

                  (a)      If the Company shall, at any time or from time to
time while this Warrant is outstanding, pay a dividend or make a distribution on
its Common Stock in shares of Common Stock, subdivide its outstanding shares of
Common Stock into a greater number of shares or combine its outstanding shares
of Common Stock into a smaller number of shares or issue by reclassification of
its outstanding shares of Common Stock any shares of its capital stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation), then the number of
Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in
effect immediately prior to the date upon which such change shall become
effective, shall be adjusted by the Company so that the Warrantholder thereafter
exercising the Warrant shall be entitled to receive the number of shares of
Common Stock or other capital stock which the Warrantholder would have received
if the Warrant had been exercised immediately prior to such event upon payment
of a Warrant Price that has been adjusted to reflect a fair allocation of the
economics of such event to the Warrantholder. Such adjustments shall be made
successively whenever any event listed above shall occur.

                                       4
<PAGE>

                  (b)      If any capital reorganization, reclassification of
the capital stock of the Company, consolidation or merger of the Company with
another corporation in which the Company is not the survivor, or sale, transfer
or other disposition of all or substantially all of the Company's assets to
another corporation shall be effected, then, as a condition of such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition, lawful and adequate provision shall be made whereby Warrantholder
shall thereafter have the right to purchase and receive upon the basis and upon
the terms and conditions herein specified and in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of this Warrant, such shares of
stock, securities or assets as would have been issuable or payable with respect
to or in exchange for a number of Warrant Shares equal to the number of Warrant
Shares immediately theretofore issuable upon exercise of this Warrant, had such
reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition not taken place, and in any such case appropriate provision shall be
made with respect to the rights and interests of Warrantholder to the end that
the provisions hereof shall thereafter be applicable, as nearly equivalent as
may be practicable in relation to any shares of stock, securities or properties
thereafter deliverable upon the exercise thereof. The Company shall not effect
any such consolidation, merger, sale, transfer or other disposition unless prior
to or simultaneously with the consummation thereof the successor corporation (if
other than the Company) resulting from such consolidation or merger, or the
corporation purchasing or otherwise acquiring such assets or other appropriate
corporation or entity shall assume the obligation to deliver to the holder of
this Warrant, at the last address of such holder appearing on the books of the
Company, such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such holder may be entitled to purchase. The provisions of
this paragraph (b) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales, transfers or other
dispositions.

         SECTION 9.        Fractional Interest. The Company shall not be
required to issue fractions of Warrant Shares upon the exercise of this Warrant.
If any fractional share of Common Stock would, except for the provisions of the
first sentence of this Section 9, be deliverable upon such exercise, the
Company, in lieu of delivering such fractional share, shall pay to the
exercising holder of this Warrant an amount in cash equal to the Fair Market
Value of such fractional share of Common Stock on the date of exercise. As used
in this Warrant, "Fair Market Value" of a share of Common Stock as of a
particular date (the "Valuation Date") shall mean the following: (a) if the
Common Stock is then listed on a national stock exchange, the closing sale price
of one share of Common Stock on such exchange on the last trading day prior to
the Valuation Date; (b) if the Common Stock is then quoted on Nasdaq, the
closing sale price of one share of Common Stock on Nasdaq on the last trading
day prior to the Valuation Date or, if no such closing sale price is available,
the average of the high bid and the low sales price quoted on Nasdaq on the last
trading day prior to the Valuation Date; or (c) if the Common Stock is not then
listed on a national stock exchange or quoted on Nasdaq, the Fair Market Value
of one share of Common Stock as of the Valuation Date, shall be determined in
good faith by the Board of Directors of the Company.

         SECTION 10.       Notices to Warrantholder. Upon the happening of any
event requiring an adjustment of the Warrant Price, the Company shall promptly
give written notice thereof to the Warrantholder at the address appearing in the
records of the Company, stating the adjusted

                                       5
<PAGE>

Warrant Price and the adjusted number of Warrant Shares resulting from such
event and setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Failure to give such notice to the
Warrantholder or any defect therein shall not affect the legality or validity of
the subject adjustment.

         SECTION 11.       Identity of Transfer Agent. The Transfer Agent for
the Common Stock is Computer Share Trust Company. Upon the appointment of any
subsequent transfer agent for the Common Stock or other shares of the Company's
capital stock issuable upon the exercise of the rights of purchase represented
by the Warrant, the Company will mail to the Warrantholder a statement setting
forth the name and address of such transfer agent.

         SECTION 12.       Notices. Unless otherwise provided, any notice
required or permitted under this Warrant shall be given in writing and shall be
deemed effectively given as hereinafter described (i) if given by personal
delivery, then such notice shall be deemed given upon such delivery, (ii) if
given by telex or telecopier, then such notice shall be deemed given upon
receipt of confirmation of complete transmittal, (iii) if given by mail, then
such notice shall be deemed given upon the earlier of (A) receipt of such notice
by the recipient or (B) three days after such notice is deposited in first class
mail, postage prepaid, and (iv) if given by an internationally recognized
overnight air courier, then such notice shall be deemed given one day after
delivery to such carrier. All notices shall be addressed as follows: if to the
Warrantholder, at its address as set forth in the Company's books and records
and, if to the Company, at the address as follows, or at such other address as
the Warrantholder or the Company may designate by ten days' advance written
notice to the other:

         SECTION 15.       No Rights as Stockholder. Prior to the exercise of
this Warrant, the Warrantholder shall not have or exercise any rights as a
