                                     ALLONGE
                                       TO
                                 PROMISSORY NOTE

            This Allonge dated as of July 13, 2000 is attached to and forms a
part of that certain Promissory Note dated May 5, 2000 (the "Note") in the
original principal amount of $5,000,000 issued by eFAX.com, a Delaware
corporation ("Borrower") in favor of JFAX.COM, Inc. ("Lender").

            The Note is hereby amended by changing the definition of "Maturity
Date" in the first sentence thereof by:

            (A) deleting the phrase "on the later of (i) August 31, 2000 and
(ii) the date which is sixty (60) days following the date, if any, upon which
the Lender terminates merger discussions with Borrower (other than following a
breach by Borrower of its obligations under the letter of intent, dated as of
April 5, 2000, between Borrower and Lender) prior to the execution of a
definitive merger agreement or upon which any such definitive merger agreement
is terminated as a result of a failure to obtain approval of the Lender's
shareholders or as a result of a material breach by the Lender thereunder (the
"Maturity Date")" and

            (B) replacing such phrase with the following: " on the later of (i)
October 31, 2000 and (ii) the date which is sixty (60) days following the date,
if any, upon which the Agreement and Plan of Merger dated as of the date hereof
(the "Merger Agreement") between and among the Borrower, Lender and JFAX.COM
Merger Sub, Inc. is terminated as a result of a failure to obtain approval of
Lender's shareholders or as a result of a material breach by Lender thereunder
(the "Maturity Date"); provided, however, that upon a "Borrower Merger Failure"
(as hereinafter defined), the Maturity Date shall be immediately accelerated to
the later of (x) August 31, 2000 and (y) the date upon which such Borrower
Merger Failure occurs (a "Borrower Merger Failure" shall be deemed to occur in
the event that any of the events described in Section 8.4(a) of the Merger
Agreement occurs or in the event that Borrower's shareholders fail to approve
the proposed merger)."

            Except as amended hereby, the Note remains unchanged and in full
force and effect.

                                 SIDE AGREEMENT

            THIS SIDE AGREEMENT (this "Agreement"), dated July 13, 2000, by and
among eFax.com (formerly known as eFax.com, Inc.), a Delaware corporation, with
headquarters located at 1378 Willow Road, Menlo Park, California (the
"Company"), Fisher Capital Ltd. and Wingate Capital Ltd. (collectively, Fisher
Capital Ltd. and Wingate Capital Ltd. are referred to as the "Investors", or
individually as an "Investor") and JFAX.COM, Inc., a Delaware corporation, with
headquarters located at 6922 Hollywood Blvd., Suite 900, Hollywood, California
("JFAX").

            WHEREAS:

            A. The Company and the Investors entered into an Exchange Agreement,
dated as of April 5, 2000 (the "Exchange Agreement").

            B. The Company and JFAX currently are engaged in discussions of a
potential merger (such merger, provided that it is on substantially the same
terms as set forth in the Draft Merger Agreement (as defined in the Exchange
Agreement between the Investors and the Company dated as of July 13, 2000 (the
"Series D Exchange Agreement")) (including without limitation, on terms no less
favorable to the Investors than the terms set forth in Exhibit B to the Draft
Merger Agreement) is referred to in this Agreement as the "Merger") in which the
Company will merge with a subsidiary of JFAX and the holders of the Company's
Common Stock, $.01 par value (the "Company Common Stock"), will receive as
consideration in connection with the Merger shares of JFAX's Common Stock, $0.01
par value (the "JFAX Common Stock").

            C. The Investors hold shares of the Company's Series B Convertible
Preferred Stock, $.01 par value (the "Series B Shares"), which, prior to the
Merger, will be exchanged into shares of the Series D Convertible Preferred
Stock, $.01 par value (the "Series D Shares"), pursuant to the terms of the
Series D Exchange Agreement.

            D. Pursuant to the terms of the Series D Exchange Agreement, prior
to the consummation of the Merger, the Company and JFAX are required to execute
this Agreement which provides for the issuance to each Investor of certain
securities of JFAX upon consummation of the Merger in exchange for the Series D
Shares in accordance with Section 4(p) of the Series D Exchange Agreement.

            E. Each Investor holds a warrant pursuant to a Series A Purchase
Agreement (as defined in the Exchange Agreement) (collectively, the "Series A
Warrants") which is exercisable for shares of the Company Common Stock.

            F. In connection with the Series A Warrants, the Company and the
Investors entered into a Registration Rights Agreement, dated May 7, 1999 (the
"Series A Registration Rights Agreement"), which provides for registration
rights

<PAGE>   2
to the Investors for shares of the Company Common Stock acquired upon the
exercise of the Series A Warrants.

            NOW THEREFORE, the Company, the Investors and JFAX hereby agree as
follows:

            1. Form of New JFAX Warrants. The Investors agree to exchange the
Series A Warrants for warrants of JFAX in the form of Exhibit A attached hereto
(the "New JFAX Warrants") at the time of the Merger. Upon issuance by JFAX of
the New JFAX Warrants, the Series A Warrants will be deemed cancelled and of no
further force or effect. At the time of the Merger, JFAX agrees to issue the New
JFAX Warrants in exchange for the Series A Warrants. JFAX agrees to use its best
efforts to ensure that the JFAX Common Stock into which the New JFAX Warrants
may be converted shall be listed on the Nasdaq National Market.

            2. Termination of the Agreements. At the time of the Merger and upon
the conversion, directly or indirectly, of all of the Series D Shares into
capital stock of JFAX and, if applicable, warrants to acquire shares of the
capital stock of JFAX as set forth in Section 4(p) of the Series D Exchange
Agreement and the exchange of the Series A Warrants for the New JFAX Warrants in
accordance with the terms of this Agreement, the Series A Purchase Agreement,
the Series A Registration Rights Agreement, the Exchange Agreement and the
Series D Exchange Agreement (except for Section 4(r) thereof) will terminate.

            3. Listing of Shares of Company Common Stock on Nasdaq. The
Investors agree that unless they specifically request in writing, for purposes
of the listing on the Nasdaq National Market of additional shares of Company
Common Stock which may be acquired upon the conversion of the Series D Shares
into Company Common Shares (the "Additional Listing"), the Company will not be
required to make the Additional Listing until the earlier of (i) the public
announcement by the Company or JFAX of the abandonment or termination of the
proposed Merger, and (ii) December 31, 2000, if the Company does not consummate
a merger transaction with JFAX and JFAX.COM Merger Sub, Inc., a Delaware
corporation and wholly owned subsidiary of JFAX, on substantially the same terms
as was disclosed in the Draft Merger Agreement (including, without limitation,
on terms no less favorable to the Investors than the terms set forth in Exhibit
B to the Draft Merger Agreement) on or prior to December 31, 2000 (the earlier
of (i) and (ii) being the "Merger Termination Date"). The Company represents
that it has previously listed 4.5 million shares of Company Common Stock which
may be acquired upon the conversion of the Series D Shares.

            4. Limitation on Exchange.

            (a) Consideration Warrant. If the number of Series D Shares that an
Investor and its affiliates hold at the time of the Merger would, if converted
and

                                       2
<PAGE>   3

absent the limitation in Section 4(p) of the Series D Exchange Agreement, result
in such Investor and its affiliates receiving a number of shares of JFAX Common
Stock in connection with the Merger which would exceed 10.00% of the number of
shares of JFAX Common Stock outstanding immediately following the Merger, then
in lieu of issuing shares of JFAX Common Stock for Series D Shares which, if
converted, would result in such Investor and its affiliates receiving a number
of shares of JFAX Common Stock in connection with the Merger which would exceed
10.00% of the number of shares of JFAX Common Stock outstanding immediately
following the Merger (such Series D Shares are referred to herein as the
"Blocked Preferred Shares"), JFAX shall issue such Investor a warrant in the
form of Exhibit B attached hereto (a "Consideration Warrant") to purchase (at an
exercise price of $0.01 per share) a number of shares of JFAX Common Stock equal
to (i) the number of Blocked Preferred Shares which such Investor holds at the
time of the Merger, multiplied by (ii) the quotient of (A) the Conversion Amount
(as defined in the Series D Certificate of Designations (as defined in the
Series D Exchange Agreement), divided by (B) the Conversion Price (as defined in
the Series D Certificate of Designations), multiplied by (iii) the number of
shares of JFAX Common Stock being issued in such Merger for each share of the
Company Common Stock outstanding. Each Consideration Warrant shall expire not
earlier than June 30, 2003, and shall contain such other terms which are set
forth in Exhibit B.

            (b) Series D Shares to be Retired. At the time of the Merger, all of
the then outstanding Series D Shares will be converted into shares of JFAX
Common Stock and the Consideration Warrants in accordance with this Agreement
and Section 4(p) of the Series D Exchange Agreement (except for cash in lieu of
fractional shares) and will no longer be outstanding and shall be cancelled and
retired. At the time of the Merger, JFAX shall issue (concurrent with the
issuance of JFAX Common Stock to the holders of the Company Common Stock) to
each Investor which holds Series D Shares at the time of the Merger in exchange
for such Investor's Series D Shares (other than Blocked Preferred Shares) a
number of shares of JFAX Common Stock equal to the product of (i) the number of
Series D Shares which such Investor holds as of the time of the Merger
(excluding any Blocked Preferred Shares, but including any Series D Shares
(other than Blocked Preferred Shares) which such Investor is not able to
convert, or with respect to which the Company is not obligated to issue Common
Stock, as of the date of the consummation of the Merger due to the limitations
of Section 5 or 14, respectively, of the Series D Certificate of Designations),
multiplied by (ii) the quotient of (A) the Conversion Amount (as defined in the
Series D Certificate of Designations), divided by (B) the Conversion Price (as
defined in the Series D Certificate of Designations), multiplied by (iii) the
number of shares of JFAX Common Stock being issued in the Merger for each share
of Company Common Stock outstanding immediately prior to the Merger.
Notwithstanding the foregoing, in no event shall an Investor be obligated to

                                       3
<PAGE>   4
exchange its Series D Shares unless such exchange is in accordance with the
requirements of Section 4(p) of the Series D Exchange Agreement.

            5. Registration of Warrants. At the time of the Merger, JFAX and the
Investors agree to enter into a registration rights agreement in the form
attached as Exhibit C hereto for the registration by JFAX of the shares of JFAX
Common Stock for which the Consideration Warrants and the New JFAX Warrants may
be exercised.

            6. Representation of Investors. The Investors have not granted and
prior to the Merger Termination Date will not grant to any other party any
rights under the Series B Shares, the Series D Shares, the Series A Warrants,
the Exchange Agreement, the Series D Exchange Agreement or the Series A
Registration Rights Agreement and have all rights to waive any rights which they
may have under such documents.

            7. Substantially Same Terms. The Investors agree that the provisions
of this Agreement shall not cause the Merger to not be on substantially the same
terms as set forth in the Draft Merger Agreement (including, without limitation,
on terms no less favorable to the Investors than the terms set forth in Exhibit
B to the Draft Merger Agreement). The parties agree that, unless waived in
writing by each of the Investors, the Merger will not be deemed to be on
substantially the same terms as set forth in the Draft Merger Agreement if the
Triggering Event (as defined in the Series D Certificate of Designations) set
forth in Section 3(b)(v) or 3(b)(vi) of the Series D Certificate of Designations
shall be deemed to have occurred.

            8. Agreements of JFAX. This Agreement, together with the definitive
Merger Agreement between JFAX and the Company, shall suffice as the written
agreements which the Company is required to obtain from JFAX pursuant to
Sections 4(p) and 4(q) of the Series D Exchange Agreement.

            9. Waiver of Appraisal Rights, Agreement to Vote. The Investors
waive any appraisal rights which they may have in connection with the Merger
pursuant to Section 262 of the Delaware General Corporation Law.

            10. Waiver of Rights. Immediately prior to the Merger, the Company
and the Investors shall execute the Waiver Agreement in the form of Exhibit D
hereto.

            11. Termination. This Agreement will terminate at the Merger
Termination Date if the Merger has not occurred by such date on substantially
the same terms as set forth in the Draft Merger Agreement (including, without
limitation, on terms no less favorable to the Investors than the terms set forth
in Exhibit B to the Draft Merger Agreement).

                                       4
<PAGE>   5

            12. Binding Effect. This Agreement will be binding upon any
affiliate of the Investors to which any Series B Shares, Series D Shares,
Company Common Stock or JFAX Common Stock may be transferred by the Investors
prior to the Merger.

            13. Counterparts. This Agreement may be executed in two or more
identical counterparts all of which shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each
party and delivered to the other parties; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

            14. Removal of Legends. Notwithstanding anything to the contrary in
the New JFAX Warrants or the Consideration Warrants, JFAX agrees that all
restrictive legends shall be removed and shall not be placed on any shares of
JFAX Common Stock issued or issuable upon exercise of the New JFAX Warrants or
the Consideration Warrants by the Investors, if (i) such Investor sells such
shares pursuant to a registration statement under the Securities Act of 1933, as
amended (the "1933 Act"), (ii) in connection with a sale transaction, such
Investor provides JFAX with an opinion of counsel, in a form reasonably
acceptable to JFAX, to the effect that a public sale, assignment or transfer of
the shares may be made without registration under the 1933 Act, or (iii) such
Investor provides JFAX assurances reasonably acceptable to JFAX that such shares
can be sold pursuant to Rule 144 under the 1933 Act without any restriction as
to the number of securities acquired as of a particular date that can then be
immediately sold.

            15. Amendments. This Agreement may only be amended by a written
agreement executed by each of the parties hereto.

                                       5
<PAGE>   6
            16. Replacement of Warrants. If following the Merger, a
Consideration Warrant or New JFAX Warrant is lost, stolen, mutilated or
destroyed, JFAX shall, upon receipt of an indemnification undertaking in a form
reasonably acceptable to JFAX, issue a new Consideration Warrant or New JFAX
Warrant, as the case may be, of like denomination and tenor as such
Consideration Warrant or New JFAX Warrant which was lost, stolen, mutilated or
destroyed.

            IN WITNESS WHEREOF, the Investors, the Company and JFAX have caused
this Agreement to be duly executed as of the date first written above.

NEITHER THE WARRANT REPRESENTED BY THIS CERTIFICATE NOR ANY OF THE SECURITIES
ISSUABLE UPON EXERCISE THEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR ANY STATE SECURITIES ACT, AND MAY NOT BE OFFERED, SOLD OR
TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER
SUCH ACTS.

Number of Shares:   195,000 multiplied by the Conversion Number
                    (as hereinafter defined)

Date of Issuance: ________, 2000

                                     WARRANT
                           To Purchase Common Stock of
                                 JFAX.COM, Inc.

          1. Grant of Warrant. THIS IS TO CERTIFY THAT for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
FISHER CAPITAL LTD. ("Holder"), is entitled at any time from and after the date
hereof and prior to May 13, 2003 (the "Expiration Date"), to exercise this
Warrant to purchase from JFAX.COM, Inc., a Delaware corporation (the "Company"),
up to a number of shares (the "Warrant Shares") of the common stock, $.01 par
value per share (the "Common Stock"), of the Company determined in accordance
with the following sentence, at an exercise price of equal to the Exercise Price
(as hereinafter defined) per Warrant Share, all on the terms and conditions and
pursuant to the provisions hereinafter set forth. The aggregate number of
Warrant Shares for which this Warrant may be exercised is equal to the product
of (x) 195,000 multiplied by (y) the Conversion Number (as hereinafter defined);
provided, however that the Company shall not effect the exercise of this Warrant
and the Holder of this Warrant shall not have the right to exercise this Warrant
to the extent that after giving effect to such exercise such Holder (together
with such Holder's affiliates) would have acquired, through the exercise of this
Warrant or otherwise, beneficial ownership of a number of shares of Common Stock
during the 60-day period ending on and including the date this Warrant was
exercised (the "60 Day Period"), that, when added to the number of shares of
Common Stock beneficially owned by such Holder (together which such Holder's
affiliates) at the beginning of the 60 Day Period, exceeds 10% of the number of
shares of Common Stock outstanding immediately after giving effect to such
exercise. For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the Holder and its affiliates or acquired by the
Holder and its affiliates, as the case may be, shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect

                                     A-I-1
<PAGE>   8
to which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (i) conversion of
the remaining, non-exercised Warrants beneficially owned by the Holder and its
affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder and its affiliates. Except as set forth in the preceding
sentence, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this
Warrant, in determining the number of outstanding shares of Common Stock the
Holder may rely on the number of outstanding shares of Common Stock as reflected
in (1) the Company's most recent Form 10-Q or Form 10-K, as the case may be, (2)
a more recent public announcement by the Company or (3) any other notice by the
Company or its transfer agent setting forth the number of shares of Common Stock
outstanding. For any reason at any time, upon the written or oral request of the
Holder of this Warrant, the Company shall within two (2) Business Days confirm
orally and in writing to the Holder the number of shares Common Stock then
outstanding. In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the exercise of this Warrant by the Holder
and it affiliates since the date as of which such number of outstanding shares
of Common Stock was reported. This Warrant is granted by the Company to the
Holder in accordance with the Agreement and Plan of Merger, dated as of July 13,
2000 (the "Merger Agreement") among the Company, eFAX.com, and JFAX.COM Merger
Sub, Inc. The "Conversion Number" shall have the meaning set forth in the Merger
Agreement. The "Exercise Price" shall be equal to a fraction, the numerator of
which is $13.95 and the denominator of which is the Conversion Number. This
Warrant shall not be valid or obligatory for any purpose until it has been
executed and delivered by the Company and accepted and agreed to by the Holder,
as set forth on the signature page hereof.

          2. Exercise. This Warrant may be exercised at any time or from time to
time, but only during the period specified in Section 1 of this Warrant, on any
day that is a business day, for all or any part of the number of shares of
Common Stock purchasable upon its exercise; provided, however, that this Warrant
shall be void and all rights represented hereby shall cease unless exercised
before the Expiration Date. In order to exercise this Warrant, in whole or in
part, the Holder hereof shall deliver to the Company at its principal office at
6922 Hollywood Boulevard, Suite 900, Los Angeles, California 90028, or at such
other office as shall be designated in writing to the Holder by the Company, (i)
a written notice of such Holder's election to exercise this Warrant, which
notice shall specify the number of shares of Common Stock to be purchased
pursuant to such exercise, (ii) cash or a certified or cashier's check payable
to the order of the Company in an amount equal to the aggregate purchase price
for all shares of Common Stock to be purchased pursuant to such exercise, or in
lieu of such payment, an election for cashless exercise as provided herein, and
(iii) this Warrant. Such notice may be given

                                     A-I-2
<PAGE>   9
by the Subscription Form appearing at the end of this Warrant. Upon receipt
thereof, the Company shall, as promptly as practicable, execute or cause to be
executed and delivered to such Holder a certificate or certificates representing
the aggregate number of full shares of Common Stock issuable upon such exercise.
The stock certificates so delivered shall be registered in the name of such
Holder or such other person as Holder shall designate. Holder acknowledges that
the stock certificates shall bear a restrictive legend comparable to that
appearing on the face of this Warrant. This Warrant shall be deemed to have been
exercised and such certificates shall be deemed to have been issued, and the
Holder or any other person so designated shall be deemed to have become a holder
of record of such shares for all purposes, as of the date said notice, together
with payment (or election of cashless exercise) and this Warrant, are received
by the Company. If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the stock certificates, deliver to the Holder
a new Warrant evidencing the right of the Holder to purchase the number of
shares of Common Stock with respect to which this Warrant has not been
exercised.

          3. Covenants as to Common Stock. The Company hereby covenants and
agrees as follow:

               (a) This Warrant is, and any Warrants issued in substitution for
or replacement of this Warrant will upon issuance be, duly authorized and
validly issued.

               (b) All Warrant Shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issues thereof.

               (c) During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved 100% of the number of shares of Common Stock needed to provide for the
exercise of the rights then represented by this Warrant and the par value of
said shares will at all times be less than or equal to the applicable Exercise
Price.

               (d) The Company shall promptly secure the listing of the shares
of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long

                                     A-I-3
<PAGE>   10
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

               (e) 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 by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant. The Company
(i) will not increase the par value of any shares of Common Stock receivable
upon the exercise of this Warrant above the Exercise Price then in effect, and
(ii) will take all such actions as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

               (f) This Warrant will be binding upon any entity succeeding to
the Company by merger, consolidation or acquisition of all or substantially all
of the Company's assets or otherwise.

          4. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, the Holder, as such, of this Warrant shall not be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the Holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of stock, reclassification
of stock, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the Holder of this Warrant of the Warrant Shares which he or she is
then entitled to receive upon the due exercise of this Warrant. In addition,
nothing contained in the Warrant shall be construed as imposing any liabilities
on the Holder to purchase any securities (upon exercise of this Warrant or
otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company.

          5. Representations of Holder.

               (a) The Holder of this Warrant, by the acceptance hereof,
represents that it is acquiring this Warrant and the Warrant Shares for its own
account for investment only and not with a view towards, or for resale in
connection with, the public sale or distribution of this Warrant or the Warrant
Shares, except pursuant to sales registered or exempted under the Securities Act
of 1933, as amended (the "Securities Act"); provided, however, that by making
the representations herein, the Holder does not

                                     A-I-4
<PAGE>   11
agree to hold this Warrant or any of the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of this Warrant and the Warrant
Shares at any time in accordance with or pursuant to a registration statement or
an exemption under the Securities Act. The Holder of this Warrant further
represents, by acceptance hereof, that, as of this date, such Holder is an
"accredited investor" as such term is defined in Rule 501(a) of Regulation D
promulgated by the Securities and Exchange Commission under the Securities Act
(an "Accredited Investor").

               (b) Upon exercise of this Warrant, except pursuant to a cashless
exercise, the Holder shall confirm, which confirmation shall be deemed to be
made by delivery of an Exercise Notice, (i) that the Warrant Shares so purchased
are being acquired its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution of
the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making such representation, the
Holder does not agree to hold any of the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of the Warrant Shares at any
time in accordance with or pursuant to a registration statement or an exemption
under the Securities Act and (ii) the Holder is an Accredited Investor.

          6. Ownership and Transfer.

               (a) The Company shall maintain at its principal executive offices
(or such other office or agency of the Company as it may designate by notice to
the Holder hereof), a register for this Warrant, in which the Company shall
record the name and address of the person in whose name this Warrant has been
issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and the Holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

               (b) This Warrant and the rights granted hereunder shall not be
assignable by the Holder hereof without the prior written consent of the
Company; provided, however, that this Warrant and the rights granted to the
Holder hereof are transferable, in whole or in part, to an Affiliate (as defined
below) of the Holder with the prior written consent of the Company, which
consent shall not be unreasonably withheld, upon surrender of this Warrant,
together with a properly executed warrant power; provided, however, that any
transfer or assignment shall be subject to the conditions set forth in Section
6(c) below. An "Affiliate" shall mean "affiliate" as such term is defined in
Rule 501(b) under the Securities Act.

               (c) The Holder of this Warrant understands that this Warrant has
not

                                     A-I-5
<PAGE>   12
been and is not expected to be, registered under the Securities Act or any state
securities laws, and may not be offered for sale, sold, assigned or transferred
unless (a) subsequently registered thereunder, or (b) the Holder shall have
delivered to the Company an opinion of counsel, in a form reasonably acceptable
to the Company, to the effect that the securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to an exemption from
such registration; provided that (i) any sale of such securities made in
reliance on Rule 144 promulgated under the Securities Act may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any resale of such securities under circumstances in which the
seller (or the person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the Securities Act) may require
compliance with some other exemption under the Securities Act or the rules and
regulations of the Securities and Exchange Commission thereunder; and (ii)
neither the Company nor any other person is under any obligation to register the
Warrants under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder.

          7. Fractional Shares. The Company shall not be required to issue
fractional shares upon the exercise of this Warrant, but instead, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be rounded
up or down to the nearest whole share (calculated at the time of final exercise
of this Warrant).

          8. Adjustment of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of the following events:

               (a) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any
time the Company shall:

               (1) take a record of the holders of its Common Stock for the
          purpose of entitling them to receive a dividend payable in, or other
          distribution of, additional shares of Common Stock,

               (2) subdivide its shares of Common Stock outstanding into a
          larger number of shares of such Common Stock, or

               (3) combine its shares of Common Stock outstanding into a smaller
          number of shares of such Common Stock,

then the Exercise Price shall be adjusted to equal the product of the Exercise
Price in effect immediately prior to such event multiplied by a fraction the
numerator of which is equal to

                                     A-I-6
<PAGE>   13
the number of shares of Common Stock outstanding immediately prior to the
event requiring such adjustment and the denominator of which is equal to the
number of shares of Common Stock outstanding immediately after giving effect to
such event. Upon any such adjustment of the Exercise Price, the Holder shall
thereafter be entitled to purchase upon the exercise of this Warrant, at the
Exercise Price resulting from such adjustment, the number of shares of Common
Stock (calculated to the nearest 1/100th of a share) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of Common Stock issuable on the exercise thereof immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

               (b) REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is any change whatsoever in, or distribution with respect to, the outstanding
Common Stock of the Company), or sell, transfer or otherwise dispose of all or
substantially all of its property, assets or business to another corporation
and, pursuant to the terms of such reorganization, reclassification, merger,
consolidation or disposition of assets, (i) shares of common stock of the
successor or acquiring corporation or of the Company (if it is the surviving
corporation) or (ii) any cash, shares of stock or other securities or property
of any nature whatsoever (including warrants or other subscription or purchase
rights) in addition to or in lieu of common stock of the successor or acquiring
corporation ("Other Property") are to be received by or distributed to the
holders of Common Stock of the Company who are holders immediately prior to such
transaction, then the Holder shall have the right thereafter to receive, upon
exercise of the Warrant, the number of shares of common stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of shares of Common Stock for which the Warrant is exercisable
immediately prior to such event. In such event, the aggregate Exercise Price
otherwise payable for the shares of Common Stock issuable upon exercise of the
Warrant shall be allocated among the shares of common stock and Other Property
receivable upon exercise of this Warrant as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets in proportion
to the respective fair market values of such shares of common stock and Other
Property as determined in good faith by the Board of Directors of the Company.
In case of any such reorganization, reclassification, merger, consolidation or
disposition of assets, the successor or acquiring corporation (if other than the
Company) shall expressly assume the due and punctual observance and performance
of each and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be reasonably deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order to
provide for adjustments of any shares of the common stock of such successor or
acquiring

                                     A-I-7
<PAGE>   14
corporation for which the Warrants thus become exercisable, which modifications
shall be as equivalent as practicable to the adjustments provided for in this
Section 8. For purposes of this Section 8, "common stock of the successor or
acquiring corporation" shall include stock of such corporation of any class that
is not preferred as to dividends or assets over any other class of stock of such
corporation and that is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities that are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event, and any
warrants or other rights to subscribe for or purchase any stock. The foregoing
provisions of this Section 8(b) shall similarly apply to successive
reorganizations, reclassification, mergers, consolidations or disposition of
assets.

               (c) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS
SECTION. The following provisions shall be applicable to the adjustments
provided for pursuant to this Section 8:

               (1) WHEN ADJUSTMENTS TO BE MADE. The adjustments required by this
          Section 8 shall be made during the period from the date of this
          Warrant and until the Expiration Date, whenever and as often as any
          specified event requiring such an adjustment shall occur. For the
          purpose of any such adjustment, any specified event shall be deemed to
          have occurred at the close of business on the date of its occurrence.

               (2) FRACTIONAL INTERESTS. In computing adjustments under this
          Section 8, fractional interests in Common Stock shall be taken into
          account to the nearest 1/100th of a share.

               (3) WHEN ADJUSTMENT NOT REQUIRED. If the Company shall take a
          record of the holders of its Common Stock for the purpose of entitling
          them to receive a dividend or distribution to which the provisions of
          Section 8 would apply, but shall, thereafter and before the
          distribution to stockholders thereof, legally abandon its plan to pay
          or deliver such dividend or distribution, then thereafter no
          adjustment shall be required by reason of the taking of such record
          and any such adjustment previously made in respect thereof shall be
          rescinded and annulled.

               (4) CERTAIN LIMITATIONS. Notwithstanding anything herein to the
          contrary, the Company agrees not to enter into any transaction that,
          by reason of any adjustment under the foregoing provisions, would
          cause the Exercise Price to be less than the par value of the Common
          Stock, if any, unless the Company first

                                     A-I-8
<PAGE>   15
reduces the par value of the Common Stock to be less than the Exercise Price
that would result from such transaction.

               (5) NOTICE OF ADJUSTMENTS. Whenever the number of shares of
          Common Stock for which the Warrant is exercisable or the Exercise
          Price shall be adjusted pursuant to this Section 8, the Company shall
          forthwith prepare a certificate to be executed by the chief financial
          officer of the Company setting forth, in reasonable detail, the event
          requiring the adjustment and the method by which such adjustment was
          calculated, specifying the number of shares of Common Stock for which
          the Warrant is exercisable and (if such adjustment was made pursuant
          to Section 8(b)) describing the number and kind of any other shares of
          stock or Other Property for which the Warrant is exercisable, and
          setting forth any related change in the Exercise Price, after giving
          effect to such adjustment or change. The Company shall promptly cause
          a signed copy of such certificate to be delivered to the Holder. The
          Company shall keep at its principal office copies of all such
          certificates and cause the same to be available for inspection at said
          office during normal business hours by the Holder.

               (6) INDEPENDENT APPLICATION. Except as otherwise provided herein,
          all subsections of this Section 8 are intended to operate
          independently of one another (but without duplication). If an event
          occurs that requires the application of more than one subsection, all
          applicable subsections shall be given independent effect without
          duplication.

               9. Cashless Exercise. Subject to the following provisions, the
Holder may elect to receive, without the payment by the Holder of any additional
consideration, Warrant Shares equal to the value of this Warrant or any portion
hereof by the surrender of this Warrant or such portion to the Company, by so
indicating on the Subscription Form attached hereto, at the office of the
Company. Any such election shall be treated as a conversion of this Warrant or
portion hereof into Warrant Shares. Thereupon, the Company shall issue to the
Holder such number of shares of Common Stock as is computed using the following
formula:

                X = Y (A-B)
                    -------
                       (A)

               where:

               X = the number of shares to be issued to the Holder pursuant to
                   this Section 9.

                                     A-I-9
<PAGE>   16
               Y = the number of shares covered by this Warrant in respect of
                   which the cashless exercise election is made pursuant to this
                   Section 9.

               A = the fair market value of one share of the Company's Common
                   Stock as determined below at the time the cashless exercise
                   election is made pursuant to this Section 9.

               B = the Exercise Price in effect under this Warrant at the time
                   the cashless exercise election is made pursuant to this
                   Section 9.

For the purposes hereof, the fair market value of one share of the Company's
Common Stock shall mean the average of the daily prices for the Company's Common
Stock on the applicable market specified below, over the latest ten (10) trading
days prior to the date of the cashless exercise, based upon:

               (a) the closing prices per share of the Company's Common Stock on
          the principal national securities exchange on which the Common Stock
          is listed or admitted to trading, or

               (b) if not listed or traded on any such exchange, the last
          reported sales prices per share on the Nasdaq National Market or the
          Nasdaq Stock Market (collectively, "Nasdaq"), or

               (c) if not listed or traded on any such exchange or Nasdaq, the
          daily average of the high and low bid prices per share as reported in
          the NASD OTC Bulletin Board.

However, if such quotations are not available during such ten trading day
period, then the cashless exercise shall be inapplicable.

               10. Applicable Law. THIS WARRANT SHALL BE INTERPRETED AND THE
RIGHTS OF THE PARTIES DETERMINED IN ACCORDANCE WITH THE LAWS OF THE UNITED
STATES APPLICABLE THERETO AND THE INTERNAL LAWS OF THE STATE OF DELAWARE.

               11. Successors and Assigns. This Warrant and the rights evidenced
hereby shall inure to the benefit of and be binding upon the permitted
successors and assigns of the Company and the Holder hereof; provided, however,
that the Holder shall not assign or transfer any of its rights or obligations
under this Warrant except as expressly permitted in Section 6.

               12. Headings. Headings of the Sections in this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

               13. Amendments. This Warrant and any terms hereof may be changed,
waived, discharged, or terminated only by an instrument in writing signed by the
party or Holder hereof against which enforcement of such change, waiver,
discharge or termination is sought.

               IN WITNESS WHEREOF, the Company has caused this Warrant to be
duly executed.

Date of Issuance: ________, 2000

                                     WARRANT
                           To Purchase Common Stock of
                                 JFAX.COM, Inc.

          1. Grant of Warrant. THIS IS TO CERTIFY THAT for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
WINGATE CAPITAL LTD. ("Holder"), is entitled at any time from and after the date
hereof and prior to May 13, 2003 (the "Expiration Date"), to exercise this
Warrant to purchase from JFAX.COM, Inc., a Delaware corporation (the "Company"),
up to a number of shares (the "Warrant Shares") of the common stock, $.01 par
value per share (the "Common Stock"), of the Company determined in accordance
with the following sentence, at an exercise price of equal to the Exercise Price
(as hereinafter defined) per Warrant Share, all on the terms and conditions and
pursuant to the provisions hereinafter set forth. The aggregate number of
Warrant Shares for which this Warrant may be exercised is equal to the product
of (x) 105,000 multiplied by (y) the Conversion Number (as hereinafter defined);
provided, however that the Company shall not effect the exercise of this Warrant
and the Holder of this Warrant shall not have the right to exercise this Warrant
to the extent that after giving effect to such exercise such Holder (together
with such Holder's affiliates) (B) would have acquired, through the exercise of
this Warrant or otherwise, beneficial ownership of a number of shares of Common
Stock during the 60-day period ending on and including the date this Warrant was
exercised (the "60 Day Period"), that, when added to the number of shares of
Common Stock beneficially owned by such Holder (together which such Holder's
affiliates) at the beginning of the 60 Day Period, exceeds 10% of the number of
shares of Common Stock outstanding immediately after giving effect to such
exercise. For purposes of the foregoing sentence, the number of shares of Common
Stock beneficially owned by the Holder and its affiliates or acquired by the
Holder and its affiliates, as the case may be, shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect

                                     A-II-1
<PAGE>   20
to which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (i) conversion of
the remaining, non-exercised Warrants beneficially owned by the Holder and its
affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder and its affiliates. Except as set forth in the preceding
sentence, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this
Warrant, in determining the number of outstanding shares of Common Stock the
Holder may rely on the number of outstanding shares of Common Stock as reflected
in (1) the Company's most recent Form 10-Q or Form 10-K, as the case may be, (2)
a more recent public announcement by the Company or (3) any other notice by the
Company or its transfer agent setting forth the number of shares of Common Stock
outstanding. For any reason at any time, upon the written or oral request of the
Holder of this Warrant, the Company shall within two (2) Business Days confirm
orally and in writing to the Holder the number of shares Common Stock then
outstanding. In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the exercise of this Warrant by the Holder
and it affiliates since the date as of which such number of outstanding shares
of Common Stock was reported. This Warrant is granted by the Company to the
Holder in accordance with the Agreement and Plan of Merger, dated as of July 13,
2000 (the "Merger Agreement") among the Company, eFAX.com, and JFAX.COM Merger
Sub, Inc. The "Conversion Number" shall have the meaning set forth in the Merger
Agreement. The "Exercise Price" shall be equal to a fraction, the numerator of
which is $13.95 and the denominator of which is the Conversion Number. This
Warrant shall not be valid or obligatory for any purpose until it has been
executed and delivered by the Company and accepted and agreed to by the Holder,
as set forth on the signature page hereof.

          2. Exercise. This Warrant may be exercised at any time or from time to
time, but only during the period specified in Section 1 of this Warrant, on any
day that is a business day, for all or any part of the number of shares of
Common Stock purchasable upon its exercise; provided, however, that this Warrant
shall be void and all rights represented hereby shall cease unless exercised
before the Expiration Date. In order to exercise this Warrant, in whole or in
part, the Holder hereof shall deliver to the Company at its principal office at
6922 Hollywood Boulevard, Suite 900, Los Angeles, California 90028, or at such
other office as shall be designated in writing to the Holder by the Company, (i)
a written notice of such Holder's election to exercise this Warrant, which
notice shall specify the number of shares of Common Stock to be purchased
pursuant to such exercise, (ii) cash or a certified or cashier's check payable
to the order of the Company in an amount equal to the aggregate purchase price
for all shares of Common Stock to be purchased pursuant to such exercise, or in
lieu of such payment, an election for cashless exercise as provided herein, and
(iii) this Warrant. Such notice may be given

                                     A-II-2

<PAGE>   21
by the Subscription Form appearing at the end of this Warrant. Upon receipt
thereof, the Company shall, as promptly as practicable, execute or cause to be
executed and delivered to such Holder a certificate or certificates representing
the aggregate number of full shares of Common Stock issuable upon such exercise.
The stock certificates so delivered shall be registered in the name of such
Holder or such other person as Holder shall designate. Holder acknowledges that
the stock certificates shall bear a restrictive legend comparable to that
appearing on the face of this Warrant. This Warrant shall be deemed to have been
exercised and such certificates shall be deemed to have been issued, and the
Holder or any other person so designated shall be deemed to have become a holder
of record of such shares for all purposes, as of the date said notice, together
with payment (or election of cashless exercise) and this Warrant, are received
by the Company. If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the stock certificates, deliver to the Holder
a new Warrant evidencing the right of the Holder to purchase the number of
shares of Common Stock with respect to which this Warrant has not been
exercised.

          3. Covenants as to Common Stock. The Company hereby covenants and
agrees as follow:

               (a) This Warrant is, and any Warrants issued in substitution for
or replacement of this Warrant will upon issuance be, duly authorized and
validly issued.

               (b) All Warrant Shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issues thereof.

               (c) During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved 100% of the number of shares of Common Stock needed to provide for the
exercise of the rights then represented by this Warrant and the par value of
said shares will at all times be less than or equal to the applicable Exercise
Price.

               (d) The Company shall promptly secure the listing of the shares
of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long

                                     A-II-3
<PAGE>   22
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

               (e) 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 by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant. The Company
(i) will not increase the par value of any shares of Common Stock receivable
upon the exercise of this Warrant above the Exercise Price then in effect, and
(ii) will take all such actions as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

               (f) This Warrant will be binding upon any entity succeeding to
the Company by merger, consolidation or acquisition of all or substantially all
of the Company's assets or otherwise.

          4. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, the Holder, as such, of this Warrant shall not be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the Holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of stock, reclassification
of stock, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the Holder of this Warrant of the Warrant Shares which he or she is
then entitled to receive upon the due exercise of this Warrant. In addition,
nothing contained in the Warrant shall be construed as imposing any liabilities
on the Holder to purchase any securities (upon exercise of this Warrant or
otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company.

          5. Representations of Holder.

               (a) The Holder of this Warrant, by the acceptance hereof,
represents that it is acquiring this Warrant and the Warrant Shares for its own
account for investment only and not with a view towards, or for resale in
connection with, the public sale or distribution of this Warrant or the Warrant
Shares, except pursuant to sales registered or exempted under the Securities Act
of 1933, as amended (the "Securities Act"); provided, however, that by making
the representations herein, the Holder does not

                                     A-II-4

<PAGE>   23
agree to hold this Warrant or any of the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of this Warrant and the Warrant
Shares at any time in accordance with or pursuant to a registration statement or
an exemption under the Securities Act. The Holder of this Warrant further
represents, by acceptance hereof, that, as of this date, such Holder is an
"accredited investor" as such term is defined in Rule 501(a) of Regulation D
promulgated by the Securities and Exchange Commission under the Securities Act
(an "Accredited Investor").

               (b) Upon exercise of this Warrant, except pursuant to a cashless
exercise, the Holder shall confirm, which confirmation shall be deemed to be
made by delivery of an Exercise Notice, (i) that the Warrant Shares so purchased
are being acquired its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution of
the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making such representation, the
Holder does not agree to hold any of the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of the Warrant Shares at any
time in accordance with or pursuant to a registration statement or an exemption
under the Securities Act and (ii) the Holder is an Accredited Investor.

          6. Ownership and Transfer.

               (a) The Company shall maintain at its principal executive offices
(or such other office or agency of the Company as it may designate by notice to
the Holder hereof), a register for this Warrant, in which the Company shall
record the name and address of the person in whose name this Warrant has been
issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and the Holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

               (b) This Warrant and the rights granted hereunder shall not be
assignable by the Holder hereof without the prior written consent of the
Company; provided, however, that this Warrant and the rights granted to the
Holder hereof are transferable, in whole or in part, to an Affiliate (as defined
below) of the Holder with the prior written consent of the Company, which
consent shall not be unreasonably withheld, upon surrender of this Warrant,
together with a properly executed warrant power; provided, however, that any
transfer or assignment shall be subject to the conditions set forth in Section
6(c) below. An "Affiliate" shall mean "affiliate" as such term is defined in
Rule 501(b) under the Securities Act.

               (c) The Holder of this Warrant understands that this Warrant has
not

                                     A-II-5
<PAGE>   24
been and is not expected to be, registered under the Securities Act or any state
securities laws, and may not be offered for sale, sold, assigned or transferred
unless (a) subsequently registered thereunder, or (b) the Holder shall have
delivered to the Company an opinion of counsel, in a form reasonably acceptable
to the Company, to the effect that the securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to an exemption from
such registration; provided that (i) any sale of such securities made in
reliance on Rule 144 promulgated under the Securities Act may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any resale of such securities under circumstances in which the
seller (or the person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the Securities Act) may require
compliance with some other exemption under the Securities Act or the rules and
regulations of the Securities and Exchange Commission thereunder; and (ii)
neither the Company nor any other person is under any obligation to register the
Warrants under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder.

          7. Fractional Shares. The Company shall not be required to issue
fractional shares upon the exercise of this Warrant, but instead, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be rounded
up or down to the nearest whole share (calculated at the time of final exercise
of this Warrant).

          8. Adjustment of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of the following events:

               (a) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any
time the Company shall:

               (1) take a record of the holders of its Common Stock for the
          purpose of entitling them to receive a dividend payable in, or other
          distribution of, additional shares of Common Stock,

               (2) subdivide its shares of Common Stock outstanding into a
          larger number of shares of such Common Stock, or

               (3) combine its shares of Common Stock outstanding into a smaller
          number of shares of such Common Stock,

then the Exercise Price shall be adjusted to equal the product of the Exercise
Price in effect immediately prior to such event multiplied by a fraction the
numerator of which is equal to

                                     A-II-6
<PAGE>   25
the number of shares of Common Stock outstanding immediately prior to the event
requiring such adjustment and the denominator of which is equal to the number of
shares of Common Stock outstanding immediately after giving effect to such
event. Upon any such adjustment of the Exercise Price, the Holder shall
thereafter be entitled to purchase upon the exercise of this Warrant, at the
Exercise Price resulting from such adjustment, the number of shares of Common
Stock (calculated to the nearest 1/100th of a share) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of Common Stock issuable on the exercise thereof immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

               (b) REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is any change whatsoever in, or distribution with respect to, the outstanding
Common Stock of the Company), or sell, transfer or otherwise dispose of all or
substantially all of its property, assets or business to another corporation
and, pursuant to the terms of such reorganization, reclassification, merger,
consolidation or disposition of assets, (i) shares of common stock of the
successor or acquiring corporation or of the Company (if it is the surviving
corporation) or (ii) any cash, shares of stock or other securities or property
of any nature whatsoever (including warrants or other subscription or purchase
rights) in addition to or in lieu of common stock of the successor or acquiring
corporation ("Other Property") are to be received by or distributed to the
holders of Common Stock of the Company who are holders immediately prior to such
transaction, then the Holder shall have the right thereafter to receive, upon
exercise of the Warrant, the number of shares of common stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of shares of Common Stock for which the Warrant is exercisable
immediately prior to such event. In such event, the aggregate Exercise Price
otherwise payable for the shares of Common Stock issuable upon exercise of the
Warrant shall be allocated among the shares of common stock and Other Property
receivable upon exercise of this Warrant as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets in proportion
to the respective fair market values of such shares of common stock and Other
Property as determined in good faith by the Board of Directors of the Company.
In case of any such reorganization, reclassification, merger, consolidation or
disposition of assets, the successor or acquiring corporation (if other than the
Company) shall expressly assume the due and punctual observance and performance
of each and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be reasonably deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order to
provide for adjustments of any shares of the common stock of such successor or
acquiring

                                     A-II-7
<PAGE>   26
corporation for which the Warrants thus become exercisable, which modifications
shall be as equivalent as practicable to the adjustments provided for in this
Section 8. For purposes of this Section 8, "common stock of the successor or
acquiring corporation" shall include stock of such corporation of any class that
is not preferred as to dividends or assets over any other class of stock of such
corporation and that is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities that are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event, and any
warrants or other rights to subscribe for or purchase any stock. The foregoing
provisions of this Section 8(b) shall similarly apply to successive
reorganizations, reclassification, mergers, consolidations or disposition of
assets.

               (c) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS
SECTION. The following provisions shall be applicable to the adjustments
provided for pursuant to this Section 8:

               (1) WHEN ADJUSTMENTS TO BE MADE. The adjustments required by this
          Section 8 shall be made during the period from the date of this
          Warrant and until the Expiration Date, whenever and as often as any
          specified event requiring such an adjustment shall occur. For the
          purpose of any such adjustment, any specified event shall be deemed to
          have occurred at the close of business on the date of its occurrence.

               (2) FRACTIONAL INTERESTS. In computing adjustments under this
          Section 8, fractional interests in Common Stock shall be taken into
          account to the nearest 1/100th of a share.

               (3) WHEN ADJUSTMENT NOT REQUIRED. If the Company shall take a
          record of the holders of its Common Stock for the purpose of entitling
          them to receive a dividend or distribution to which the provisions of
          Section 8 would apply, but shall, thereafter and before the
          distribution to stockholders thereof, legally abandon its plan to pay
          or deliver such dividend or distribution, then thereafter no
          adjustment shall be required by reason of the taking of such record
          and any such adjustment previously made in respect thereof shall be
          rescinded and annulled.

               (4) CERTAIN LIMITATIONS. Notwithstanding anything herein to the
          contrary, the Company agrees not to enter into any transaction that,
          by reason of any adjustment under the foregoing provisions, would
          cause the Exercise Price to be less than the par value of the Common
          Stock, if any, unless the Company first

                                     A-II-8
<PAGE>   27
reduces the par value of the Common Stock to be less than the Exercise Price
that would result from such transaction.

               (5) NOTICE OF ADJUSTMENTS. Whenever the number of shares of
          Common Stock for which the Warrant is exercisable or the Exercise
          Price shall be adjusted pursuant to this Section 8, the Company shall
          forthwith prepare a certificate to be executed by the chief financial
          officer of the Company setting forth, in reasonable detail, the event
          requiring the adjustment and the method by which such adjustment was
          calculated, specifying the number of shares of Common Stock for which
          the Warrant is exercisable and (if such adjustment was made pursuant
          to Section 8(b)) describing the number and kind of any other shares of
          stock or Other Property for which the Warrant is exercisable, and
          setting forth any related change in the Exercise Price, after giving
          effect to such adjustment or change. The Company shall promptly cause
          a signed copy of such certificate to be delivered to the Holder. The
          Company shall keep at its principal office copies of all such
          certificates and cause the same to be available for inspection at said
          office during normal business hours by the Holder.

               (6) INDEPENDENT APPLICATION. Except as otherwise provided herein,
          all subsections of this Section 8 are intended to operate
          independently of one another (but without duplication). If an event
          occurs that requires the application of more than one subsection, all
          applicable subsections shall be given independent effect without
          duplication.

          9. Cashless Exercise. Subject to the following provisions, the Holder
may elect to receive, without the payment by the Holder of any additional
consideration, Warrant Shares equal to the value of this Warrant or any portion
hereof by the surrender of this Warrant or such portion to the Company, by so
indicating on the Subscription Form attached hereto, at the office of the
Company. Any such election shall be treated as a conversion of this Warrant or
portion hereof into Warrant Shares. Thereupon, the Company shall issue to the
Holder such number of shares of Common Stock as is computed using the following
formula:

                   X = Y (A-B)
                       -------
                         (A)

          where:

          X = the number of shares to be issued to the Holder pursuant to this
              Section 9.

                                     A-II-9
<PAGE>   28
          Y = the number of shares covered by this Warrant in respect of which
              the cashless exercise election is made pursuant to this Section 9.

          A = the fair market value of one share of the Company's Common Stock
              as determined below at the time the cashless exercise election is
              made pursuant to this Section 9.

          B = the Exercise Price in effect under this Warrant at the time the
              cashless exercise election is made pursuant to this Section 9.

For the purposes hereof, the fair market value of one share of the Company's
Common Stock shall mean the average of the daily prices for the Company's Common
Stock on the applicable market specified below, over the latest ten (10) trading
days prior to the date of the cashless exercise, based upon:

               (a) the closing prices per share of the Company's Common Stock on
          the principal national securities exchange on which the Common Stock
          is listed or admitted to trading, or

               (b) if not listed or traded on any such exchange, the last
          reported sales prices per share on the Nasdaq National Market or the
          Nasdaq Stock Market (collectively, "Nasdaq"), or

               (c) if not listed or traded on any such exchange or Nasdaq, the
          daily average of the high and low bid prices per share as reported in
          the NASD OTC Bulletin Board.

However, if such quotations are not available during such ten trading day
period, then the cashless exercise shall be inapplicable.

          10. Applicable Law. THIS WARRANT SHALL BE INTERPRETED AND THE RIGHTS
OF THE PARTIES DETERMINED IN ACCORDANCE WITH THE LAWS OF THE UNITED STATES
APPLICABLE THERETO AND THE INTERNAL LAWS OF THE STATE OF DELAWARE.

          11. Successors and Assigns. This Warrant and the rights evidenced
hereby shall inure to the benefit of and be binding upon the permitted
successors and assigns of the Company and the Holder hereof; provided, however,
that the Holder shall not assign or transfer any of its rights or obligations
under this Warrant except as expressly permitted in Section 6.

                                    A-II-10
<PAGE>   29
          12. Headings. Headings of the Sections in this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

          13. Amendments. This Warrant and any terms hereof may be changed,
waived, discharged, or terminated only by an instrument in writing signed by the
party or Holder hereof against which enforcement of such change, waiver,
discharge or termination is sought.

          IN WITNESS WHEREOF, the Company has caused this Warrant to be duly
executed.

          1. Grant of Warrant. THIS IS TO CERTIFY THAT for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
[FISHER] [WINGATE] CAPITAL LTD. ("Holder"), is entitled at any time from and
after the date hereof and prior to June 30, 2003 (the "Expiration Date"), to
exercise this Warrant to purchase from JFAX.COM, Inc., a Delaware corporation
(the "Company"), up to ________ shares (the "Warrant Shares") of the common
stock, $.01 par value per share (the "Common Stock"), of the Company, at an
exercise price (the "Exercise Price") of $.01 per Warrant Share, all on the
terms and conditions and pursuant to the provisions hereinafter set forth. The
aggregate number of Warrant Shares for which this Warrant may be exercised is
________; provided, however that the Company shall not effect the exercise of
this Warrant and the Holder of this Warrant shall not have the right to exercise
this Warrant to the extent that after giving effect to such exercise such Holder
(together with such Holder's affiliates) would have acquired, through the
exercise of this Warrant or otherwise, beneficial ownership of a number of
shares of Common Stock during the 60-day period ending on and including the date
this Warrant was exercised (the "60 Day Period"), that, when added to the number
of shares of Common Stock beneficially owned by such Holder (together which such
Holder's affiliates) at the beginning of the 60 Day Period, exceeds 10% of the
number of shares of Common Stock outstanding immediately after giving effect to
such exercise. For purposes of the foregoing sentence, the number of shares of
Common Stock beneficially owned by the Holder and its affiliates or acquired by
the Holder and its affiliates, as the case may be, shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (i) conversion of
the remaining, non-exercised Warrants beneficially owned by the Holder

                                      B-1

<PAGE>   32
and its affiliates and (ii) exercise or conversion of the unexercised or
unconverted portion of any other securities of the Company subject to a
limitation on conversion or exercise analogous to the limitation contained
herein beneficially owned by the Holder and its affiliates. Except as set forth
in the preceding sentence, beneficial ownership shall be calculated in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended. For purposes of this Warrant, in determining the number of outstanding
shares of Common Stock the Holder may rely on the number of outstanding shares
of Common Stock as reflected in (1) the Company's most recent Form 10-Q or Form
10-K, as the case may be, (2) a more recent public announcement by the Company
or (3) any other notice by the Company or its transfer agent setting forth the
number of shares of Common Stock outstanding. For any reason at any time, upon
the written or oral request of the Holder of this Warrant, the Company shall
within two (2) Business Days confirm orally and in writing to the Holder the
number of shares Common Stock then outstanding. In any case, the number of
outstanding shares of Common Stock shall be determined after giving effect to
the exercise of this Warrant by the Holder and it affiliates since the date as
of which such number of outstanding shares of Common Stock was reported. This
Warrant is granted by the Company to the Holder in accordance with the Agreement
and Plan of Merger, dated as of July 13, 2000 (the "Merger Agreement") among the
Company, eFAX.com, and JFAX.COM Merger Sub, Inc. This Warrant shall not be valid
or obligatory for any purpose until it has been executed and delivered by the
Company and accepted and agreed to by the Holder, as set forth on the signature
page hereof.

          2. Exercise. This Warrant may be exercised at any time or from time to
time, but only during the period specified in Section 1 of this Warrant, on any
day that is a business day, for all or any part of the number of shares of
Common Stock purchasable upon its exercise; provided, however, that this Warrant
shall be void and all rights represented hereby shall cease unless exercised
before the Expiration Date. In order to exercise this Warrant, in whole or in
part, the Holder hereof shall deliver to the Company at its principal office at
6922 Hollywood Boulevard, Suite 900, Los Angeles, California 90028, or at such
other office as shall be designated in writing to the Holder by the Company, (i)
a written notice of such Holder's election to exercise this Warrant, which
notice shall specify the number of shares of Common Stock to be purchased
pursuant to such exercise, (ii) cash or a certified or cashier's check payable
to the order of the Company in an amount equal to the aggregate purchase price
for all shares of Common Stock to be purchased pursuant to such exercise, or in
lieu of such payment, an election for cashless exercise as provided herein, and
(iii) this Warrant. Such notice may be given by the Subscription Form appearing
at the end of this Warrant. Upon receipt thereof, the Company shall, as promptly
as practicable, execute or cause to be executed and delivered to such Holder a
certificate or certificates representing the aggregate number of full shares of
Common Stock issuable upon such exercise. The stock certificates so delivered
shall be registered in the name of such Holder or such other person as Holder
shall

                                      B-2
<PAGE>   33
designate. Holder acknowledges that the stock certificates shall bear a
restrictive legend comparable to that appearing on the face of this Warrant.
This Warrant shall be deemed to have been exercised and such certificates shall
be deemed to have been issued, and the Holder or any other person so designated
shall be deemed to have become a holder of record of such shares for all
purposes, as of the date said notice, together with payment (or election of
cashless exercise) and this Warrant, are received by the Company. If this
Warrant shall have been exercised in part, the Company shall, at the time of
delivery of the stock certificates, deliver to the Holder a new Warrant
evidencing the right of the Holder to purchase the number of shares of Common
Stock with respect to which this Warrant has not been exercised.

          3. Covenants as to Common Stock. The Company hereby covenants and
agrees as follow:

               (a) This Warrant is, and any Warrants issued in substitution for
or replacement of this Warrant will upon issuance be, duly authorized and
validly issued.

               (b) All Warrant Shares which may be issued upon the exercise of
the rights represented by this Warrant will, upon issuance, be validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issues thereof.

               (c) During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved 100% of the number of shares of Common Stock needed to provide for the
exercise of the rights then represented by this Warrant and the par value of
said shares will at all times be less than or equal to the applicable Exercise
Price.

               (d) The Company shall promptly secure the listing of the shares
of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

               (e) The Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger,

                                      B-3
<PAGE>   34
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 by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant. The Company
(i) will not increase the par value of any shares of Common Stock receivable
upon the exercise of this Warrant above the Exercise Price then in effect, and
(ii) will take all such actions as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

               (f) This Warrant will be binding upon any entity succeeding to
the Company by merger, consolidation or acquisition of all or substantially all
of the Company's assets or otherwise.

          4. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, the Holder, as such, of this Warrant shall not be
entitled to vote or receive dividends or be deemed the holder of shares of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the Holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action (whether any reorganization, issue of stock, reclassification
of stock, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the
issuance to the Holder of this Warrant of the Warrant Shares which he or she is
then entitled to receive upon the due exercise of this Warrant. In addition,
nothing contained in the Warrant shall be construed as imposing any liabilities
on the Holder to purchase any securities (upon exercise of this Warrant or
otherwise) or as a stockholder of the Company, whether such liabilities are
asserted by the Company or by creditors of the Company.

          5. Representations of Holder.

               (a) The Holder of this Warrant, by the acceptance hereof,
represents that it is acquiring this Warrant and the Warrant Shares for its own
account for investment only and not with a view towards, or for resale in
connection with, the public sale or distribution of this Warrant or the Warrant
Shares, except pursuant to sales registered or exempted under the Securities Act
of 1933, as amended (the "Securities Act"); provided, however, that by making
the representations herein, the Holder does not agree to hold this Warrant or
any of the Warrant Shares for any minimum or other specific term and reserves
the right to dispose of this Warrant and the Warrant Shares at any time in
accordance with or pursuant to a registration statement or an exemption under
the Securities Act. The Holder of this Warrant further represents, by acceptance
hereof, that, as of this date, such Holder is an "accredited investor" as such
term is defined in

                                      B-4
<PAGE>   35
Rule 501(a) of Regulation D promulgated by the Securities and Exchange
Commission under the Securities Act (an "Accredited Investor").

               (b) Upon exercise of this Warrant, except pursuant to a cashless
exercise, the Holder shall confirm, which confirmation shall be deemed to be
made by delivery of an Exercise Notice, (i) that the Warrant Shares so purchased
are being acquired its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution of
the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making such representation, the
Holder does not agree to hold any of the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of the Warrant Shares at any
time in accordance with or pursuant to a registration statement or an exemption
under the Securities Act and (ii) the Holder is an Accredited Investor.

          6. Ownership and Transfer.

               (a) The Company shall maintain at its principal executive offices
(or such other office or agency of the Company as it may designate by notice to
the Holder hereof), a register for this Warrant, in which the Company shall
record the name and address of the person in whose name this Warrant has been
issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and the Holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

               (b) This Warrant and the rights granted hereunder shall not be
assignable by the Holder hereof without the prior written consent of the
Company; provided, however, that this Warrant and the rights granted to the
Holder hereof are transferable, in whole or in part, to an Affiliate (as defined
below) of the Holder with the prior written consent of the Company, which
consent shall not be unreasonably withheld, upon surrender of this Warrant,
together with a properly executed warrant power; provided, however, that any
transfer or assignment shall be subject to the conditions set forth in Section
6(c) below. An "Affiliate" shall mean "affiliate" as such term is defined in
Rule 501(b) under the Securities Act.

               (c) The Holder of this Warrant understands that this Warrant has
not been and is not expected to be, registered under the Securities Act or any
state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (a) subsequently registered thereunder, or (b) the Holder
shall have delivered to the Company an opinion of counsel, in a form reasonably
acceptable to the Company, to the effect that the securities to be sold,
assigned or transferred may be sold, assigned or

                                      B-5
<PAGE>   36
transferred pursuant to an exemption from such registration; provided that (i)
any sale of such securities made in reliance on Rule 144 promulgated under the
Securities Act may be made only in accordance with the terms of said Rule and
further, if said Rule is not applicable, any resale of such securities under
circumstances in which the seller (or the person through whom the sale is made)
may be deemed to be an underwriter (as that term is defined in the Securities
Act) may require compliance with some other exemption under the Securities Act
or the rules and regulations of the Securities and Exchange Commission
thereunder; and (ii) neither the Company nor any other person is under any
obligation to register the Warrants under the Securities Act or any state
securities laws or to comply with the terms and conditions of any exemption
thereunder.

          7. Fractional Shares. The Company shall not be required to issue
fractional shares upon the exercise of this Warrant, but instead, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be rounded
up or down to the nearest whole share (calculated at the time of final exercise
of this Warrant).

          8. Adjustment of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of the following events:

               (a) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any
time the Company shall:

               (i) take a record of the holders of its Common Stock for the
          purpose of entitling them to receive a dividend payable in, or other
          distribution of, additional shares of Common Stock,

               (ii) subdivide its shares of Common Stock outstanding into a
          larger number of shares of such Common Stock, or

               (iii) combine its shares of Common Stock outstanding into a
          smaller number of shares of such Common Stock,

then the Exercise Price shall be adjusted to equal the product of the Exercise
Price in effect immediately prior to such event multiplied by a fraction the
numerator of which is equal to the number of shares of Common Stock outstanding
immediately prior to the event requiring such adjustment and the denominator of
which is equal to the number of shares of Common Stock outstanding immediately
after giving effect to such event. Upon any such adjustment of the Exercise
Price, the Holder shall thereafter be entitled to purchase upon the exercise of
this Warrant, at the Exercise Price resulting from such

                                      B-6
<PAGE>   37
adjustment, the number of shares of Common Stock (calculated to the nearest
1/100th of a share) obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares of Common Stock
issuable on the exercise thereof immediately prior to such adjustment and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

               (b) REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is any change whatsoever in, or distribution with respect to, the outstanding
Common Stock of the Company), or sell, transfer or otherwise dispose of all or
substantially all of its property, assets or business to another corporation
and, pursuant to the terms of such reorganization, reclassification, merger,
consolidation or disposition of assets, (i) shares of common stock of the
successor or acquiring corporation or of the Company (if it is the surviving
corporation) or (ii) any cash, shares of stock or other securities or property
of any nature whatsoever (including warrants or other subscription or purchase
rights) in addition to or in lieu of common stock of the successor or acquiring
corporation ("Other Property") are to be received by or distributed to the
holders of Common Stock of the Company who are holders immediately prior to such
transaction, then the Holder shall have the right thereafter to receive, upon
exercise of the Warrant, the number of shares of common stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of shares of Common Stock for which the Warrant is exercisable
immediately prior to such event. In such event, the aggregate Exercise Price
otherwise payable for the shares of Common Stock issuable upon exercise of the
Warrant shall be allocated among the shares of common stock and Other Property
receivable upon exercise of this Warrant as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets in proportion
to the respective fair market values of such shares of common stock and Other
Property as determined in good faith by the Board of Directors of the Company.
In case of any such reorganization, reclassification, merger, consolidation or
disposition of assets, the successor or acquiring corporation (if other than the
Company) shall expressly assume the due and punctual observance and performance
of each and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be reasonably deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order to
provide for adjustments of any shares of the common stock of such successor or
acquiring corporation for which the Warrants thus become exercisable, which
modifications shall be as equivalent as practicable to the adjustments provided
for in this Section 8. For purposes of this Section 8, "common

                                      B-7
<PAGE>   38
stock of the successor or acquiring corporation" shall include stock of such
corporation of any class that is not preferred as to dividends or assets over
any other class of stock of such corporation and that is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities that are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event, and any warrants or other rights to subscribe
for or purchase any stock. The foregoing provisions of this Section 8(b) shall
similarly apply to successive reorganizations, reclassification, mergers,
consolidations or disposition of assets.

               (c) DISTRIBUTION OF ASSETS AND REPURCHASE RIGHTS. If, at any time
after the issuance of this Warrant, the Company shall declare or make any
dividend or other distribution of its assets (or rights to acquire its assets)
to holders of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities,
property or options by way of dividend, spin off, reclassification, corporate
rearrangement or other transaction), then the holder of this Warrant will be
entitled to such dividend paid and distributions made to the holders of Common
Stock to the same extent as if such holder had held the number of shares of
Common Stock acquirable upon complete exercise of this Warrant (without regard
to any limitations on exercise of this Warrant) immediately before and on the
date on which a record is taken for holders of Common Stock entitled to receive
such dividend or distribution, or, if no such record is taken, the date as of
which the record holders of Common Stock are to be determined for such dividend
or distribution. Payments under the preceding sentence shall be made
concurrently with the dividend or distribution to the holders of the Common
Stock. In addition to any adjustments pursuant to Section 8 , if at any time the
Company grants, issues or sells any options, convertible securities or rights to
purchase stock, warrants, securities or other property pro rata to the record
holders of any class of Common Stock (the "Purchase Rights"), then the holder of
this Warrant will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which such holder could have
acquired if such holder had held the number of shares of Common Stock acquirable
upon complete exercise of this Warrant (without regard to the limitations on the
exercise of this Warrant set forth in the proviso to the second sentence of
Section 1 hereof) immediately before the date on which a record is taken for the
grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of Common Stock are to be determined for
the grant, issue or sale of such Purchase Rights.

               (d) OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS
SECTION. The following provisions shall be applicable to the adjustments
provided for pursuant to this Section 8:

                                      B-8
<PAGE>   39
               (1) WHEN ADJUSTMENTS TO BE MADE. The adjustments required by this
          Section 8 shall be made during the period from the date of this
          Warrant and until the Expiration Date, whenever and as often as any
          specified event requiring such an adjustment shall occur. For the
          purpose of any such adjustment, any specified event shall be deemed to
          have occurred at the close of business on the date of its occurrence.

               (2) FRACTIONAL INTERESTS. In computing adjustments under this
          Section 8, fractional interests in Common Stock shall be taken into
          account to the nearest 1/100th of a share.

               (3) WHEN ADJUSTMENT NOT REQUIRED. If the Company shall take a
          record of the holders of its Common Stock for the purpose of entitling
          them to receive a dividend or distribution to which the provisions of
          Section 8 would apply, but shall, thereafter and before the
          distribution to stockholders thereof, legally abandon its plan to pay
          or deliver such dividend or distribution, then thereafter no
          adjustment shall be required by reason of the taking of such record
          and any such adjustment previously made in respect thereof shall be
          rescinded and annulled.

               (4) CERTAIN LIMITATIONS. Notwithstanding anything herein to the
          contrary, the Company agrees not to enter into any transaction that,
          by reason of any adjustment under the foregoing provisions, would
          cause the Exercise Price to be less than the par value of the Common
          Stock, if any, unless the Company first reduces the par value of the
          Common Stock to be less than the Exercise Price that would result from
          such transaction. Alternatively, the Company may stipulate that, at
          the time of any exercise of all or a portion of this Warrant, the
          Exercise Price shall be adjusted, if necessary, for purposes of such
          exercise to equal the par value of the Common Stock (but not more than
          the $0.01 par value as currently in effect), but if such adjustment
          results in an increase in the Exercise Price from that which would
          otherwise be applicable, then the Company shall simultaneously
          increase the number of Warrant Shares issuable upon such exercise, in
          the amount necessary to preserve the value to the Holder resulting
          from such exercise utilizing the same formula and definitions as are
          applicable in Section 9 in the case of a cashless exercise.

               (5) NOTICE OF ADJUSTMENTS. Whenever the number of shares of
          Common Stock for which the Warrant is exercisable or the Exercise
          Price shall be adjusted pursuant to this Section 8, the Company shall
          forthwith prepare a certificate to be executed by the chief financial
          officer of the Company setting

                                      B-9
<PAGE>   40
          forth, in reasonable detail, the event requiring the adjustment and
          the method by which such adjustment was calculated, specifying the
          number of shares of Common Stock for which the Warrant is exercisable
          and (if such adjustment was made pursuant to Section 8(b)) describing
          the number and kind of any other shares of stock or Other Property for
          which the Warrant is exercisable, and setting forth any related change
          in the Exercise Price, after giving effect to such adjustment or
          change. The Company shall promptly cause a signed copy of such
          certificate to be delivered to the Holder. The Company shall keep at
          its principal office copies of all such certificates and cause the
          same to be available for inspection at said office during normal
          business hours by the Holder.

               (6) INDEPENDENT APPLICATION. Except as otherwise provided herein,
          all subsections of this Section 8 are intended to operate
          independently of one another (but without duplication). If an event
          occurs that requires the application of more than one subsection, all
          applicable subsections shall be given independent effect without
          duplication.

          9. Cashless Exercise. Subject to the following provisions, the Holder
may elect to receive, without the payment by the Holder of any additional
consideration, Warrant Shares equal to the value of this Warrant or any portion
hereof by the surrender of this Warrant or such portion to the Company, by so
indicating on the Subscription Form attached hereto, at the office of the
Company. Any such election shall be treated as a conversion of this Warrant or
portion hereof into Warrant Shares. Thereupon, the Company shall issue to the
Holder such number of shares of Common Stock as is computed using the following
formula:

              X = Y (A-B)
                  -------
                     (A)

          where:

          X = the number of shares to be issued to the Holder pursuant to this
              Section 9.

          Y = the number of shares covered by this Warrant in respect of which
              the cashless exercise election is made pursuant to this Section 9.

          A = the fair market value of one share of the Company's Common Stock
              as determined below at the time the cashless exercise election is
              made pursuant to this Section 9.

                                      B-10
<PAGE>   41
          B = the Exercise Price in effect under this Warrant at the time the
              cashless exercise election is made pursuant to this Section 9.

For the purposes hereof, the "fair market value" of one share of the Company's
Common Stock shall mean the average of the daily prices for the Company's Common
Stock on the applicable market specified below, over the latest ten (10) trading
days prior to the date of the cashless exercise, based upon:

               (a) the closing prices per share of the Company's Common Stock on
          the principal national securities exchange on which the Common Stock
          is listed or admitted to trading, or

               (b) if not listed or traded on any such exchange, the last
          reported sales prices per share on the Nasdaq National Market or the
          Nasdaq Stock Market (collectively, "Nasdaq"), or

               (c) if not listed or traded on any such exchange or Nasdaq, the
          daily average of the high and low bid prices per share as reported in
          the NASD OTC Bulletin Board.

However, if such quotations are not available during such ten trading day
period, then the cashless exercise shall be inapplicable.

          2. REGISTRATION RIGHTS.

               (a) SHELF REGISTRATION.

                    (i) The Company shall prepare and file with the Commission
on or prior to the Filing Date a Registration Statement for a resale offering to
be made on a continuous basis pursuant to Rule 415 covering all of the
Registrable Securities (the "Initial Shelf Registration"). The Initial Shelf
Registration shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Securities for resale by the Holders. The
Company shall use its reasonable efforts to cause the Initial Shelf Registration
to be declared effective under the Securities Act on or prior to the
Effectiveness Date and to keep the Shelf Registration Continuously Effective
under the Securities Act until the Expiration Date (the "Effectiveness Period"),
or such shorter period ending when (i) all Registrable Securities covered by the
Shelf Registration have been sold, or (ii) a Subsequent Shelf Registration
covering all of the Registrable Securities has been declared effective under the
Securities Act.

                    (ii) If the Initial Shelf Registration or any Subsequent
Shelf Registration ceases to be effective for any reason at any time during the
Effectiveness Period (other than because of the sale of all of the Registrable
Securities registered thereunder), the Company shall use its reasonable efforts
to obtain the prompt withdrawal of any order suspending the effectiveness
thereof, and in any event shall within forty-five (45) business days of such
cessation of effectiveness amend the Initial or Subsequent Shelf Registration in
a manner reasonably expected to obtain the withdrawal of the order suspending
the effectiveness thereof, or file an additional "shelf" Registration Statement
pursuant to Rule 415 covering all of the Registrable Securities (a "Subsequent
Shelf Registration"). If a Subsequent Shelf Registration is filed, the Company
shall use its reasonable efforts to cause the Subsequent Shelf Registration to
be declared effective as soon as practicable after such filing and to keep such
Registration Statement Continuously Effective until the end of the Effectiveness
Period.

                    (iii) The Company shall supplement and amend the Initial
Shelf Registration or Subsequent Shelf Registration, as the case may be, if
required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration, if required
by the Securities Act.

               (b) REGISTRATION STATEMENT FORM. The Company may, if permitted by
law, effect any registration required hereunder by the filing of a Registration
Statement on Form S-3 (or any successor or similar short-form registration
statement).

               (c) EXPENSES. The Company shall pay all Registration Expenses
incurred in connection with the registration of Registrable Securities pursuant
to Section 2(a).

               (d) EFFECTIVE REGISTRATION STATEMENT. Any registration pursuant
to this Agreement shall not be deemed to have been effected unless it has become
effective with the Commission.

               (e) CONFLICTING INSTRUCTIONS FROM HOLDERS.

                    (i) The Company may rely and shall be protected in relying
upon any resolution, certificate, opinion, request, communication, demand,
receipt or other paper or

                                      C-3
<PAGE>   47
document in good faith believed by it to be genuine and to have been signed or
presented by the proper party or parties.

                    (ii) In the event the Company receives conflicting
instructions regarding any action to be taken or withheld hereunder, the Company
may suspend further action relating to such action until such time as the
conflicting instructions are resolved by the parties giving the same or until
the Company is instructed to take or withhold the requested action by a final
order from which no appeal may be taken issued by a court of competent
jurisdiction.

          3. REGISTRATION PROCEDURES.

               (a) Whenever the Company effects the registration of any
Registrable Securities under the Securities Act hereunder, the Company, as
expeditiously as possible and subject to the terms and conditions herein, will
use its reasonable efforts to:

                    (i) prepare and file with the Commission the requisite
registration statement to effect such registration and to cause such
registration to become effective and remain effective as provided herein;

                    (ii) prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection therewith as may be necessary to keep such registration statement
Continuously Effective and to comply with the provisions of the Securities Act
with respect to the disposition of all securities covered by such registration
statement in accordance with the intended method of disposition by the Selling
Holders thereof until such time as all of such securities have been disposed of
in accordance with the intended methods of disposition by the Selling Holders
thereof set forth in such registration statement or, if earlier, until the
Expiration Date;

                    (iii) furnish to the Selling Holders such number of
conformed copies of such registration statement and of each such amendment and
supplement thereto (in each case including all exhibits), such number of copies
of the prospectus contained in such registration statement (including each
preliminary prospectus and any summary prospectus) and any other prospectus
filed under the Securities Act, in conformity with the requirements of the
Securities Act;

                    (iv) register or qualify all Registrable Securities covered
by such registration statement under such other United States state securities
or blue sky laws of such jurisdictions as the Selling Holders shall reasonably
request, to keep such registration statement qualification in effect for so long
as such registration remains in effect, and take any other action which may be
reasonably necessary or advisable to enable the Selling Holders to consummate
the disposition in such jurisdictions of the Registrable Securities owned by the
Selling Holders in accordance with the intended method of disposition by the
Selling Holders thereof, except that the Company shall not for any such purpose
be required to (a) qualify generally to do business as a foreign corporation in
any jurisdiction wherein it would not but for the requirements of this
subdivision (iv) be obligated to be so qualified, (b) subject itself to taxation
in any such jurisdiction or (c) consent to general service of process in any
such jurisdiction;

                    (v) in any underwritten offering, and if reasonable and
customary in the context of such offering, use its reasonable efforts to furnish
to the Selling Holders a signed counterpart, addressed to the Selling Holders as
sellers of Registrable Securities (and the underwriters, if any), of

                                      C-4

<PAGE>   48
                    (x) an opinion of counsel for the Company, dated the
               effective date of such registration statement (or, if such
               registration includes an underwritten public offering, dated the
               date of the closing under the underwriting agreement), reasonably
               satisfactory to the Selling Holders in their reasonable judgment,
               and

                    (y) a "comfort" letter, reasonably satisfactory to the
               Selling Holders dated the effective date of such registration
               statement (or, if such registration includes an underwritten
               public offering, dated the date of the closing under the
               underwriting agreement), signed by the independent public
               accountants who have certified the Company's financial statements
               included in such registration statement,

               covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
the accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to the underwriters in underwritten public
offerings of securities and, in the case of the accountants' letter, such other
financial matters as such seller or such Holder (or the underwriters, if any)
may reasonably request;

                    (vi) immediately notify the Selling Holders, at any time
when a prospectus is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in a
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances under which they were made, and promptly prepare and furnish to
the Selling Holders a reasonable number of copies of a supplement to or an
amendment of such prospectus and registration statement as may be necessary so
that, as thereafter delivered to the purchasers of such securities, such
prospectus shall not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made;

                    (vii) comply with all applicable rules and regulations of
the Commission, and make available to its security holders, as soon as
reasonably practicable, an earnings statement covering the period of at least
twelve (12) months, but not more than eighteen (18) months, beginning with the
first full calendar month after the effective date of such registration
statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act;

                    (viii) provide a transfer agent and registrar for all
Registrable Securities covered by such registration statement not later than the
effective date of such registration statement;

                    (ix) list all Registrable Securities covered by such
registration statement on any securities exchange on which any of the Common
Stock is then listed; and

                    (x) use every reasonable effort to obtain the withdrawal of
any order suspending the effectiveness of a registration statement, or the
lifting of any suspension of the qualification (or exemption from qualification)
of any of the Registrable Securities for sale in any jurisdiction, at the
earliest possible moment.

                                      C-5
<PAGE>   49
               (b) As a condition of these registration rights set forth herein,
the Company may require each Selling Holder, at its own expense, to furnish the
Company with such information regarding such Selling Holder's ownership of the
Company's securities and the plan of distribution of such securities as the
Company may from time to time reasonably request in writing, and the Selling
Holders agree to provide such information as is reasonably requested.

               (c) The Selling Holders agree (A) that upon receipt of any notice
from the Company of the happening of any event of the kind described in
subdivision (vi) of Section 3(a), the Selling Holders will forthwith discontinue
their disposition of Registrable Securities pursuant to the registration
statement relating to such Registrable Securities until the Selling Holders'
receipt of the copies of the supplemented or amended prospectus contemplated by
subdivision (vi) of Section 3(a) and, if so directed by the Company, will
deliver to the Company all copies, other than permanent file copies, then in the
Selling Holders' possession of the prospectus relating to such Registrable
Securities current at the time of receipt of such notice and (B) that they will
immediately notify the Company, at any time when a prospectus relating to the
registration of such Registrable Securities is required to be delivered under
the Securities Act, of the happening of any event as a result of which
information previously furnished by the Selling Holders to the Company for
inclusion in such prospectus contains an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
under which they were made.

               (d) Notwithstanding anything in this Agreement to the contrary,
the Company will not be required to file any registration statement hereunder if
it receives an opinion of counsel of recognized expertise in Securities Act
matters, to the effect that the sale of the Registrable Securities in the manner
contemplated by the Selling Holders may be effected without registration
regardless of the identity or status of the buyer(s) of such Registrable
Securities. Also, the Company will not be required to file any registration
statement to cover Registrable Securities that are already registered pursuant
to a previous resale registration statement that is effective and available for
use by the Holders of such Registrable Securities to effect sales thereof at
such time.

          4. UNDERWRITTEN OFFERINGS.

               (a) UNDERWRITTEN OFFERINGS. If requested by the underwriters for
any underwritten offering including the Selling Holders pursuant to a
registration under Section 2, the Company will enter into an underwriting
agreement with such underwriters for such offering and with the Selling Holders,
such agreement to be in form and substance reasonably satisfactory to the
Company, the Selling Holders and the underwriters and to contain such
representations and warranties by the Company and such other terms as are
customarily contained in agreements of this type, including, without limitation,
indemnities to the effect and to the extent substantially as provided in Section
6. The Selling Holders shall be a party to such underwriting agreement and may,
at their option (reasonably exercised), require that any or all of the
representations and warranties by, and the other agreements on the part of, the
Company to and for the benefit of such underwriters shall also be made to and
for the benefit of the Selling Holders and that any or all of the conditions
precedent to the obligations of such underwriters under such underwriting
agreement be conditions precedent to the obligations of the Selling Holders.

                                      C-6
<PAGE>   50
               (b) SELECTION OF UNDERWRITERS. If a registration pursuant to
Section 2 involves an underwritten offering, then the Company will be entitled
to select the underwriter or underwriters and the Underwriters' Representative
therefor.

          5. INDEMNIFICATION; CONTRIBUTION. If any Registrable Securities are
included in a registration statement under this Agreement:

               (a) To the extent permitted by applicable law, the Company shall
indemnify and hold harmless each Selling Holder, each Person, if any, who
controls such Selling Holder within the meaning of the Securities Act, and each
officer, director, partner, agent and employee of such Selling Holder and such
controlling Person, against any and all losses, claims, damages, liabilities and
expenses (joint or several), including reasonable attorneys' fees and
disbursements and expenses of investigation, incurred by such party pursuant to
any actual or threatened action, suit, proceeding or investigation, or to which
any of the foregoing Persons may become subject under the Securities Act, the
Exchange Act or any other federal or state laws, insofar as such losses, claims,
damages, liabilities and expenses arise out of or are based upon any of the
following statements, omissions or violations (collectively a "Violation"):

                    (i) Any untrue statement or alleged untrue statement of a
material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained therein, or any amendments
or supplements thereto;

                    (ii) The omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading; or

                    (iii) Any violation or alleged violation by the Company of
the Securities Act, the Exchange Act, any applicable state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
applicable state securities law;

provided, however, that the indemnification required by this Section 5(a) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or expense if such settlement is effected without the consent of the
Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim, damage, liability
or expense to the extent (and only to the extent) that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished to the Company by any indemnified party expressly
for use in connection with such registration; provided, further, that the
indemnity agreement contained in this Section 5 shall not apply to any
underwriter to the extent that any such loss is based on or arises out of an
untrue statement or alleged untrue statement of a material fact, or an omission
or alleged omission to state a material fact, contained in or omitted from any
preliminary prospectus if the final prospectus shall correct such untrue
statement or alleged untrue statement, or such omission or alleged omission, and
a copy of the final prospectus has not been sent or given to such person at or
prior to the confirmation of sale to such person if such underwriter was under
an obligation to deliver such final prospectus and failed to do so. The Company
shall also indemnify underwriters participating in the distribution and each
person who controls any such underwriter (within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act) to the same extent as
provided above with respect to the indemnification of the Selling Holders. The
Company may also require in any underwriting agreement that it signs, reasonable
indemnification and contribution agreements in favor of the Company from the
underwriters and the Selling Holders which are selling Registrable Securities in
such underwritten offering.

<PAGE>   51
               (b) Promptly after receipt by an indemnified party under this
Section 5 of notice of the commencement of any action, suit, proceeding,
investigation or threat thereof made in writing for which such indemnified party
may make a claim under this Section 5, such indemnified party shall deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel at its own expense except as provided
below. The failure to deliver written notice to the indemnifying party within a
reasonable time following the commencement of any such action, if and to the
extent prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
6 but shall not relieve the indemnifying party of any liability that it may have
to any indemnified party otherwise than pursuant to this Section 5. Any fees and
expenses incurred by the indemnified party (including any fees and expenses
incurred in connection with investigating or preparing to defend such action or
proceeding) shall be paid to the indemnified party, as incurred, within sixty
(60) days of written notice thereof to the indemnifying party (regardless of
whether it is ultimately determined that an indemnified party is not entitled to
indemnification hereunder, but in such event such amounts shall be refunded).
Any such indemnified party shall have the right to employ separate counsel in
any such action, claim or proceeding and to participate in the defense thereof,
but the fees and expenses of such counsel shall be the expenses of such
indemnified party unless (i) the indemnifying party has agreed to pay such fees
and expenses or (ii) the indemnifying party shall have failed to promptly assume
the defense of such action, claim or proceeding or (iii) the named parties to
any such action, claim or proceeding (including any impleaded parties) include
both such indemnified party and the indemnifying party, and such indemnified
party shall have been advised by counsel that there may be one or more legal
defenses available to it which are different from or in addition to those
available to the indemnifying party and that the assertion of such defenses
would create a conflict of interest such that counsel employed by the
indemnifying party could not faithfully represent the indemnified party (in
which case, if such indemnified party notifies the indemnifying party in writing
that it elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such action, claim or proceeding on behalf of such indemnified party, it being
understood, however, that the indemnifying party shall not, in connection with
any one such action, claim or proceeding or separate but substantially similar
or related actions, claims or proceedings in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the reasonable
fees and expenses of more than one separate firm of attorneys (together with
appropriate local counsel) at any time for all such indemnified parties, unless
in the reasonable judgment of such indemnified party a conflict of interest may
exist between such indemnified party and any other of such indemnified parties
with respect to such action, claim or proceeding, in which event the
indemnifying party shall be obligated to pay the reasonable fees and expenses of
such additional counsel or counsels). No indemnifying party shall be liable to
an indemnified party for any settlement of any action, proceeding or claim
without the written consent of the indemnifying party, which consent shall not
be unreasonably withheld.

               (c) If the indemnification required by this Section 5 from the
indemnifying party is unavailable to an indemnified party hereunder in respect
of any losses, claims, damages, liabilities or expenses referred to in this
Section 5:

                                      C-8
<PAGE>   52
                    (i) The indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and indemnified parties in connection with the actions
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to,
among other things, whether any Violation has been committed by, or relates to
information supplied by, such indemnifying party or indemnified parties, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such Violation. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in
Section 5(a), any legal or other fees or expenses reasonably incurred by such
party in connection with any investigation or proceeding.

                    (ii) The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(c) were determined by pro
rata allocation or by any other method of allocation which does not take into
account the equitable considerations referred to in Section 5(c)(i). No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

               (d) If indemnification is available under this Section 5, the
indemnifying parties shall indemnify each indemnified party to the full extent
provided in this Section 5 without regard to the relative fault of such
indemnifying party or indemnified party or any other equitable consideration
referred to in Section 5(c).

               (e) The obligations of the Company and the Selling Holders of
Registrable Securities under this Section 5 shall survive the completion of any
offering of Registrable Securities pursuant to a registration statement under
this Agreement, and otherwise.

          6. COVENANTS OF THE COMPANY. The Company hereby agrees and covenants
as follows:

               The Company shall file as and when applicable, on a timely basis,
all reports required to be filed by it under the Exchange Act. If, after the
Company has first become a reporting company under the Exchange Act, thereafter
the Company is not required to file reports pursuant to the Exchange Act,
thereupon the request of any Holder of Registrable Securities, the Company shall
make publicly available the information specified in subparagraph (c)(2) of Rule
144 of the Securities Act, and take such further action as may be reasonably
required from time to time and as may be within the reasonable control of the
Company, to enable the Holders to transfer Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 under the Securities Act or any similar rule or regulation
hereafter adopted by the Commission.

          7. MISCELLANEOUS.

               7.1 NOTICES. All notices, requests, claims, demands, waivers and
other communications required or permitted hereunder shall be in writing and

                             MUTUAL GENERAL RELEASE

         This Mutual General Release (the "RELEASE") is made as of ____ __, 2000
by and between eFax.com (formerly known as eFax.com, Inc.), a Delaware
corporation ("EFAX"), JFAX.COM, Inc., a Delaware corporation ("JFAX" and,
collectively with EFAX, the "ISSUERS"), Fisher Capital Ltd., a Cayman Islands

("WINGATE" and, collectively with Fisher, the "HOLDERS").

         NOW, THEREFORE, in consideration of the foregoing, and for other good

acknowledged, the parties agree as follows:

1. Waivers and Releases.

         (a) In further consideration for the execution of the Side Agreement
and the consummation of the transactions contemplated thereby, effective on the

its heirs, executors, administrators, devisees, trustees, partners, directors,

permitted by law, any and all claims, rights and causes of action, whether known
or unknown (collectively, the "ISSUER CLAIMS"), that any of the Issuer Releasing
Persons had or currently has against (i) the Holders, (ii) any of the Holders'
respective current or former parents, shareholders, affiliates, subsidiaries,
predecessors or assigns, or (iii) any of the Holders' or such other persons' or
entities' current or former officers, directors, employees, agents, principals,
investors, signatories, advisors, consultants, spouses, heirs, estates,
executors, attorneys, auditors and associates and members of

                                      D-1
<PAGE>   57

their immediate families (collectively, the "HOLDER RELEASED PERSONS"), arising

Agreement).

         (b) In consideration of the foregoing, effective on the Effective Date
each Holder, severally and not jointly, on behalf of itself and its heirs,
executors, administrators, devisees, trustees, partners, directors, officers,

unknown (collectively, the "HOLDER CLAIMS"), that any of the Holder Releasing
Persons had or currently has against (i) the Issuers, (ii) any of the Issuers'
respective current or former parents, shareholders, affiliates, subsidiaries,

2. California Matters.

         (a) It is the intention of the parties that effective as of the
Effective Date this release shall be effective as a full and final accord and
satisfactory release of each and every matter specifically or generally referred
to. In furtherance of this intention, the parties acknowledge that each is
familiar with Section 1542 of the Civil Code of the State of California
("Section 1542"), which provides as follows:

         A general release does not extend to claims a creditor does not know or
         suspect to exist in his favor at the time of executing the release,
         which if known to him must have materially affected his settlement with
         the debtor.

         (b) The parties hereto waive and relinquish any rights and benefits
which they may have under Section 1542, including the right to seek relief from
the terms and conditions of this release for any reason whatsoever. The parties
acknowledge that they may hereafter discover facts in addition to or different
from those which they now know or believe to be true as regards the subject of
this release, but it is their intention to fully and finally forever settle and
release any

                                      D-2
<PAGE>   58

and all matters, disputes and differences, known or unknown, suspected and
unsuspected, which do now exist, may exist or heretofore have existed between
them arising out of or relating to the Transaction Documents or arising out of
or relating to matters leading up to the consummation of the Merger (other than
arising out of or relating to the Side Agreement). In furtherance of this
intention, the releases herein shall be and remain in effect as full and
complete releases notwithstanding the discovery or existence of any such
additional or different facts.

         (c) The parties warrant and represent to one another that they know and
understand the effect and import of the provisions of Section 1542.

3. Subject Matter of Release. Each party acknowledges that the parties to this
Release specifically intend to exclude the subject matter of this Release from
Section 6 and Section 7 of the Registration Rights Agreement (as defined in the
Series A Purchase Agreement), the Side Agreement (including the Consideration
Warrants and the New JFAX Warrants (each as defined in the Side Agreement)) and
the registration rights agreement referred to in Section 5 of the Side Agreement
(the "WARRANTS REGISTRATION RIGHTS AGREEMENT") and agree that this Release does
not relate to the same subject matter of the Side Agreement (including the
Consideration Warrants and the New JFAX Warrants), the Warrants Registration
Rights Agreement and Section 6 and Section 7 of the Registration Rights
Agreement. Accordingly, this Release does not affect any claim which any Issuer
Releasing Person or Holder Releasing Person may have under the Side Agreement,
the Consideration Warrants, the New JFAX Warrants, the Warrants Registration
Rights Agreement or Section 6 or Section 7 of the Registration Rights Agreement.

4. Effective Date. None of the releases in this Release shall be effective or
have any force or effect unless and until the later of (a) the consummation of
the Merger on substantially the terms set forth in the Draft Merger Agreement
(as defined in the Series D Exchange Agreement) (including, without limitation,
on terms no less favorable to the Investors than the terms set forth in Exhibit
B to the Draft Merger Agreement), provided such merger is consummated on or
prior to December 31, 2000 and (b) the consummation of the transactions
contemplated by the Side Agreement concurrent with the consummation of the
Merger.

5. Amendments. This Release may not be modified except by a written document
signed by each of the Holders and each of the Issuers or their respective
successors.

6. Governing Law. This Release will be governed by and construed in accordance
with the laws of the State of California without regard to conflicts of law
principles.

7. Acknowledgment. Each party hereto has read and understands this Release, has
had the opportunity to consult with an attorney prior to signing it, and
voluntarily enters into it with full knowledge of its terms and conditions and
that such terms and conditions are binding on.
