                          EMPLOYEE STOCK PURCHASE PLAN
                      (as amended through January 26, 2000)

1.       PURPOSE:

               The Good Guys, Inc. EMPLOYEE STOCK PURCHASE PLAN (the "Plan") is
designed to foster continued cordial employee relations, to encourage and assist
its employees and the employees of any present or future subsidiaries in
acquiring a stock ownership interest in The Good Guys, Inc. (the "Corporation")
and to help them provide for their future security. The Plan is intended to be
an Employee Stock Purchase Plan under Internal Revenue Code Section 423.

2.       STOCK SUBJECT TO THE PLAN:

               Subject to adjustment pursuant to Section 12 of the Plan, the
aggregate number of shares of Common Stock (the "shares") which may be sold
under the Plan is 3,600,000. The shares may be authorized, but unissued, or
reacquired shares of Common Stock of the Corporation. The Corporation, during
the term of the Plan, shall at all times reserve and keep available, such number
of shares as shall be sufficient to satisfy the requirements of the Plan.

3.       PERIODS:

                  The Plan originally provided for six-month periods ending on
the last day of June and December of each year, with the exception that the
first period under the Plan commenced on February 6, 1986 and ended on June 30,
1986. Effective as of September 29, 1999, the Plan was amended to provide for a
continuation of the six-month period through December 31, 1999, with respect to
those members of the Plan who were participants as of July 1, 1999, but to
provide for three-month periods ending on the last day of March, June, September
and December of each year for members of the Plan enrolling for the first time
after July 1, 1999 and for all members after December 31, 1999, with the first
three-month period to commence on October 11, 1999 and to end on December 31,
1999. As used in this Plan hereinafter, the term "period" shall mean as to those
members participating in the Plan as of July 1, 1999, the period from July 1,
1999 through December 31, 1999, and as to those members eligible to participate
for the period October 11, 1999 through December 31, 1999 and for periods after
December 31, 1999, the three-month periods ending on the last day of March,
June, September and December of each year.

year for each calendar year in which such option is outstanding at any time, or
(ii) more than 2,000 shares of stock under the Plan in any period.

               For purposes of this Plan, "subsidiary" shall mean a corporation
of which not less than fifty percent (50%) of the voting shares are held by the
Corporation or a subsidiary of the Corporation.

5.       JOINING THE PLAN:

               Any eligible employee's participation in the Plan shall be

employee completes, signs, and returns to the Corporation, or one of its present
or future subsidiaries, a Stock Purchase Plan Application and Payroll Deduction
Authority form indicating his or her acceptance and agreement to the Plan.
Membership of any employee in the Plan is entirely voluntary.

               Any employee receiving shares shall have no rights with respect
to continuation of employment, nor with respect to continuation of any
particular Corporation business, policy or product.

6.       MEMBER'S CONTRIBUTIONS:

               Each member shall elect to make contributions by payroll
deduction of any percentage up to fifteen percent (15%) of his or her gross
compensation.

               Subject to the maximum described above, a member may elect in
writing to increase or decrease his or her rate of contribution; such change
will become effective the first day of the period following receipt by the
Corporation of such written election.

               The amount of each member's contribution shall be held by the
Corporation in a special account and such contributions, free of any obligation
of the Corporation to pay interest thereon, shall be credited to such member's
individual account as of the last day of the month during which the compensation
from which the contributions were deducted was paid.

               No member will be permitted to make contributions for any period
during which he or she is not receiving pay from the Corporation or one of its
present or future subsidiaries.

7.       ISSUANCE OF SHARES:

               On the last trading day of each period so long as the Plan shall
remain in effect, and provided the member has not before that date advised the
Corporation that he or she does not wish shares purchased for his or her account
on that date, the Corporation shall apply the funds credited to the member's
account as of that date to the purchase of authorized but unissued shares of its
Common Stock in units of one share or multiples thereof.

               The cost to each member for the shares so purchased shall be
eighty-five percent (85%) of the lower of:

               1. The mean between the average bid and ask prices of the stock

or more securities exchanges the average of the closing prices on all such

the sum required to purchase one share shall, unless otherwise requested by the
member, be held in the member's account for use during the next period. Any
moneys remaining in such member's account by reason of his or her prior election
not to purchase shares in a given period, as aforesaid, or moneys remaining in
such member's account by reason of application of the provisions of the next
paragraph hereof, shall be promptly returned to the member. The Corporation
shall as expeditiously as possible after the last day of each period issue to
the member entitled thereto the certificate evidencing the shares issuable to
him or her as provided herein.

               Notwithstanding anything above to the contrary, (a) if the number
of shares all members desire to purchase at the end of any period exceeds the
number of shares then available under the Plan, the shares available shall be
allocated among such members in proportion to their contributions during the
period; and (b) no funds in an employee's account shall be applied to the
purchase of shares and no shares hereunder shall be issued unless such shares
are covered by an effective registration statement under the Securities Act of
1933, as amended, or by an exemption therefrom.

               EFFECTIVE AS TO THOSE MEMBERS WHO PARTICIPATE IN THE PLAN FOR THE
PERIOD COMMENCING ON OCTOBER 11, 1999 AND ENDING ON DECEMBER 31, 1999 AND AS TO
ALL MEMBERS FOR PERIODS AFTER DECEMBER 31, 1999, THE SHARES PURCHASED CANNOT BE

CERTIFICATE REPRESENTING THE SHARES.

8.       TERMINATION OF MEMBERSHIP:

               A member's membership in the Plan will be terminated when the
member (a) voluntarily elects to withdraw his or her entire account, (b) resigns
or is discharged from the Corporation or one of its present or future
subsidiaries, (c) dies, or (d) does not receive pay from the Corporation or one
of its present or future subsidiaries for twelve (12) consecutive months, unless
this period is due to illness, injury or for other reasons approved by the
persons or person appointed by the Corporation to administer the Plan as
provided in Paragraph 10 below. Upon termination of membership, the terminated
member shall not be entitled to rejoin the Plan until the first day of the
period immediately following the period in which the termination occurs. Upon
termination of membership, the member shall be entitled to the amount of his or
her individual account within fifteen (15) days after termination.

effective as of the date it is signed and shall be controlling over any
disposition by will or otherwise.

               Upon the death of a member his or her account shall be paid or
distributed to the beneficiary or beneficiaries designated by such member, or in
the absence of such designation, to the executor or administrator of his or her
estate, and in either event the Corporation shall not be under any further
liability to anyone. If more than one beneficiary is designated, then each
beneficiary shall receive an equal portion of the account unless the member
indicates to the contrary in his or her designation, provided that the
Corporation may in its sole discretion make distributions in such form as will
avoid the creation of fractional shares.

10.      ADMINISTRATION OF THE PLAN:

               The Plan shall be administered by such officers or other
employees of the Corporation as the Corporation may from time to time select,
and the persons so selected shall be responsible for the administration of the
Plan. All costs and expenses incurred in administering the Plan shall be paid by
the Corporation. Any taxes applicable to the member's account shall be charged
or credited to the member's account by the Corporation.

11.      MODIFICATION AND TERMINATION:

               The Corporation expects to continue the Plan until such time as
the shares reserved for issuance under the Plan have been sold. The Corporation
reserves, however, the right to amend, alter, or terminate the Plan in its
discretion. Upon termination, each member shall be entitled to the amount of his
or her individual account within thirty (30) days after termination.

stock dividend, stock split, reverse stock split, recapitalization,
reorganization, merger, consolidation, acquisition, separation, or like change
in the capital structure of the Corporation.

               No rights of any employee under this Plan shall be assignable by
him or her, by operation of law, or otherwise, except to the extent that a
member is permitted to designate a beneficiary or beneficiaries as hereinabove
provided, and except to the extent permitted by the law of descent and
distribution if no such beneficiary be designated. Prior to the issuance of any
shares under this Plan, each employee member shall be required to sign a
statement as set forth in Exhibit "A" attached hereto and incorporated herein.

14.      PARTICIPATION IN OTHER PLANS:

from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Investor's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of such Investor set forth herein in order to
determine the availability of such exemptions and the eligibility of such
Investor to acquire the Securities.

           (b) No Governmental Review. Such Investor understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the

the merits of the offering of the Securities.

           (c) Transfer or Resale. Such Investor understands that: (i) the
Securities have not been and are not being registered under the 1933 Act or any
state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (A) subsequently registered thereunder, (B) such Investor
shall have delivered to the Company an opinion of counsel, in a form reasonably
acceptable to the Company, to the effect that such Securities to be sold,
assigned or transferred may be sold, assigned or transferred pursuant to an
exemption from such registration, or (C) such Investor provides the Company with
assurances reasonably acceptable to the Company that such Securities can be
sold, assigned or transferred pursuant to Rule 144 promulgated under the 1933
Act, as amended, (or a successor rule thereto) ("RULE 144"); (ii) any sale of

the 1933 Act or the rules and regulations of the SEC thereunder; and (iii)
neither the Company nor any other person is under any obligation to register
such Securities under the 1933 Act or any state securities laws or to comply

paragraph of this Section 2(d), the certificates or other instruments
representing the Preferred Shares and the stock certificates representing the

substantially the following form (and a stop-transfer order may be placed
against transfer of such stock certificates):

           THE  SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT
           BEEN  REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933,  AS
           AMENDED,   OR  APPLICABLE   STATE   SECURITIES   LAWS.  THE

           FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH
           A BONA FIDE MARGIN ACCOUNT.

The legend set forth above shall be removed and the Company shall issue a
certificate or other instrument without such legend to the holder of the

securities laws, (i) such Securities are registered for sale under the 1933 Act,
(ii) in connection with a sale transaction, such holder provides the Company
with an opinion of counsel, in a form reasonably acceptable to the Company, to
the effect that a public

                                        3

validly authorized, executed and delivered on behalf of such Investor and
constitutes valid and binding agreements of such Investor enforceable against
such Investor in accordance with its terms, subject as to enforceability to
general principles of equity and to applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation and other similar laws relating to, or
affecting generally, the enforcement of applicable creditors' rights and

financial condition or prospects of the Company and its Subsidiaries, if any,
taken as a whole, or on the transactions contemplated hereby or by the
agreements and instruments to be entered into in connection herewith, or on the
authority or ability of the Company to perform its obligations under the
Transaction Documents (as defined below). The Company has no Subsidiaries except
as set forth on Schedule 3(a). DocuMagix, Inc. has no or only deminimus assets
and has no liabilities in excess of $250,000.

           b. Authorization; Enforcement; Validity. (i) The Company has the
requisite corporate power and authority to enter into and perform this
Agreement, the Series B Certificate

the reservation for issuance and the issuance of the Conversion Shares issuable
upon conversion thereof, have been duly authorized by the Company's Board of
Directors and no further consent or authorization is required by the Company,
its Board of Directors or its stockholders (except such stockholder approval as
may be required (A) by the Nasdaq National Market for the issuance of a number
of Conversion Shares which is greater than 20% of the number of shares of Common
Stock outstanding on the Closing Date ("20% APPROVAL") or (B) to increase the
number of authorized shares of Common Stock of the Company), (iii) this
Agreement and the Irrevocable Transfer Agent Instructions have been duly
executed and delivered by the Company, (iv) the Transaction Documents constitute
the valid and binding obligations of the Company enforceable against the Company
in accordance with their terms, except as such enforceability may be limited by
general principles of equity or applicable bankruptcy, insolvency,

the circumstances under which they were made, not misleading. As of their
respective dates, the financial statements of the Company included in the SEC
Documents complied as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto, or (ii) in the case of unaudited interim
statements, to the extent they may exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the

any advice given by any of the Investor or any of their respective
representatives or agents in connection with the Transaction Documents and the
transactions contemplated hereby and thereby is merely incidental to such

affiliates, nor any person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to

integrated with prior offerings by the Company for purposes of the 1933 Act or
any applicable stockholder approval provisions, including, without limitation,
under the rules and regulations of any exchange or automated quotation system on
which any of the securities of the Company are listed or designated. Neither the

(i.e., tacks) to the holding period for the Series A Preferred Stock.

           (l) Right to Exchange Series B Preferred Shares. If the Company does
not consummate a merger transaction with JFAX.COM or an affiliate of JFAX.COM on

           (m) Right of First Refusal. Subject to the exceptions described
below, following the Company's receipt of a Series C Election Notice the Company
and its Subsidiaries shall not contract with any party for any equity financing
(including any debt financing with an equity component) or issue any equity
securities of the Company or any Subsidiary or securities convertible or
exchangeable into or for equity securities of the Company or any Subsidiary
(including debt securities with an equity component) in any form ("FUTURE
OFFERINGS") during the period beginning on the date of the Company's receipt of
such Series C Election Notice and ending on, and including, May 13, 2000, unless
it shall have first delivered to each Investor or a designee appointed by such
Investor written notice (the "FUTURE OFFERING NOTICE") describing the proposed
Future Offering, including the terms and conditions thereof, and providing each
Investor an option to purchase up to its Aggregate Percentage (as defined below)
of the securities to be issued in such Future Offering, as of the date of
delivery of the Future Offering Notice, in the Future Offering (the limitations
referred to in this and the preceding sentence are collectively referred to as
the "CAPITAL RAISING LIMITATIONS"). For purposes of this Section 4(m),
"AGGREGATE PERCENTAGE" at any time with respect to any Investor shall mean the
percentage obtained by dividing (i) the aggregate number of the Series B
Preferred Shares initially issued to such Investor by (ii) the aggregate number
of the Series B Preferred Shares initially issued to all the Investors. An
Investor can exercise its option to participate in a Future Offering by
delivering written notice thereof to participate to the Company within five (5)
business days after receipt of a Future Offering Notice, which notice shall
state the quantity of securities being offered in the Future Offering that such
Investor will purchase, up to its Aggregate Percentage, and that number of
securities it is willing to purchase in excess of its Aggregate Percentage. In
the event that one or more Investors fail to elect to purchase up to each such
Investor's Aggregate Percentage, then each Investor which has indicated that it
is willing to purchase a number of securities in such Future Offering in excess
of its Aggregate Percentage shall be entitled to purchase its pro rata portion
(determined in the same manner as described in the preceding sentence) of the
securities in the Future Offering which one or more of the Investors have not
elected to purchase. In the event the Investors fail to elect to fully
participate in the Future Offering within the periods described in this Section
4(m), the Company shall have 60 days thereafter to sell the securities of the
Future Offering that the Investors did not elect to purchase, upon terms and
conditions, no more favorable to the purchasers thereof than specified in the
Future Offering Notice. In the event the Company has not sold such securities of
the Future Offering within such 60 day period, the Company shall not thereafter
issue or sell such securities without first offering such securities to the
Investors in the manner provided in this Section 4(m). The Capital Raising
Limitations shall not apply to (i) a loan from a commercial bank which does not
have any equity feature, (ii) any transaction involving the Company's issuances
of securities (A) as consideration in a merger or consolidation, (B) in
connection with any strategic partnership or joint venture (the primary purpose
of which is not to raise equity capital), (C) as consideration for the
acquisition of a business, product, license or other assets by the Company, or
(D) equipment lease financing, (iii) the issuance of Common Stock in a firm
commitment, underwritten public offering, (iv) the issuance of securities upon
exercise or conversion of the Company's options, warrants or other

                                       12

<PAGE>   13

convertible securities outstanding as of the date hereof, (v) the grant of
additional options or warrants, or the issuance of additional securities, under
any Company stock option plan, restricted stock plan or stock purchase plan for
the benefit of the Company's employees, officers, directors or consultants for
services provided to the Company. The Investors shall not be required to
participate or exercise their right of first refusal with respect to a
particular Future Offering in order to exercise their right of first refusal
with respect to later Future Offerings.

           (n) Right to Exchange Series C Preferred Shares. Subject to the
exceptions described below, so long as any Series C Preferred Shares are
outstanding, if the Company issues or agrees to issue any equity securities or
any instrument convertible into or exercisable or exchangeable for equity
securities of the Company (other than pursuant to a firm commitment,
underwritten public offering) ("NEW EQUITY SECURITIES") after the first date on
which the Company receives a Series C Election Notice, the Company shall provide
written notice thereof via facsimile and overnight courier to each holder of
Preferred Shares ("NEW FINANCING NOTICE") at least ten (10) days prior to the
date that the Company enters into any agreement with respect to any New Equity
Securities or issues any New Equity Securities. Within one business day after
each issuance of New Equity Securities, the Company shall make an irrevocable
exchange offer to each holder of Preferred Shares on such terms and conditions
as each such holder shall reasonably require to exchange any or all of such
holder's Preferred Shares for a like amount (based on the following formula to
value each Preferred Share: the Stated Value plus any accrued and unpaid
dividends) of the New Equity Securities. Each such exchange offer shall remain
open until the earlier of (i) the date which is 15 business days after the
receipt by each holder of Preferred Shares of the New Financing Notice or (ii)
such time as all of the holders of Preferred Shares accept or reject, in
writing, such exchange offer (the "EXCHANGE OFFER NOTICE PERIOD").
Notwithstanding the foregoing, a holder of Preferred Shares shall not be
entitled pursuant to this Section 4(n) to exchange such Preferred Shares for
securities issued by the Company as part of (i) a loan from a commercial bank
which does not have any equity feature, (ii) any transaction involving the
Company's issuances of securities (A) as consideration in a merger or
consolidation, (B) in connection with any strategic partnership or joint venture
(the primary purpose of which is not to raise equity capital), (C) as
consideration for the acquisition of a business, product, license or other
assets by the Company, or (D) equipment lease financing, (iii) the issuance of
Common Stock in a firm commitment, underwritten public offering, (iv) the
issuance of securities upon exercise or conversion of the Company's options,
warrants or other convertible securities outstanding as of April 1, 2000, (v)
the grant of additional options or warrants, or the issuance of additional
securities, under any Company stock option plan, restricted stock plan or stock
purchase plan for the benefit of the Company's employees, officers, directors or
consultants for services provided to the Company.

           (o) Reports Under the 1934 Act for Rule 144. With a view to making
available to the Investors the benefits of Rule 144 promulgated under the 1933

                      such requirements and the filing of such reports and other
                      documents is required for the applicable provisions of
                      Rule 144; and

           iii.       furnish to each Investor so long as such Investor owns any

                      statement by the Company that it has complied with the
                      reporting requirements of Rule 144, the 1933 Act and the

                      information as may be reasonably requested to permit the
                      investors to sell such securities pursuant to Rule 144

of JFAX.COM's common stock ("JFAX.COM COMMON STOCK") to each holder of Series B
Preferred Shares, concurrent with the issuance of JFAX.COM Common Stock to the
holders of the Company's Common Stock, equal to the product of (i) the number
Series B Preferred Shares which such holder holds as of the time of such merger
(including the Series B Preferred Shares such holder is not able to convert as
of the date of the consummation of such merger due to the limitations of Section
5 or Section 14 of the Series B Certificate of Designations), multiplied by (ii)

JFAX.COM Common Stock, which new warrant shall be form and substance reasonably
satisfactory to such Investors.

           (r) Restriction on Sales Following Merger. If the Closing has
occurred and the Company consummates a merger transaction with JFAX.COM or an
affiliate of JFAX.COM on terms substantially similar to the terms set forth in
the Letter of Intent on or before November 30, 2000, then beginning immediately
following each Investor's receipt of the Merger Closing Notice (as defined
below), each Investor agrees that following receipt of written notice (the
"MERGER CLOSING NOTICE") from JFAX.COM that such merger has been consummated
neither such Investor nor any of its affiliates shall sell during any calendar
month ending on or after the date of such Investor's receipt of the Merger
Closing Notice (beginning with the first calendar month which ends on or after
the date of such Investor's receipt of the Merger Closing Notice), more than 10%
of such Investor's JFAX.COM Merger Shares (as defined below) on a cumulative
basis (with partial calendar months prorated). "JFAX.COM MERGER SHARES" means
the number of shares of JFAX.COM Common Stock which such Investor received
pursuant to the merger of the Company into JFAX.COM or an affiliate of JFAX.COM.

           (s) Trading Restrictions. Each Investor agrees that during the period
beginning on and including the date of this Agreement and ending on and
including the first date on or after the consummation of a merger of the Company
into JFAX.COM or an affiliate of JFAX.COM on terms substantially similar to the
terms set forth in the Letter of Intent, neither such Investor nor any of such
Investor's affiliates shall engage in any transaction constituting a "short
sale" (as defined in Rule 3b-3 of the 1934 Act) of the JFAX.COM Common Stock,
including without limitation the purchase of a "put option" or the sale of a
"call option" on JFAX.COM Common Stock; provided, however, the restrictions set
forth in this sentence shall not apply at any time on and after the earlier of
the date of a Merger Termination (as defined in Section 4(l)) and the date on
which this Agreement is terminated in accordance with Section 9(l). Each
Investor agrees that during the period (A) beginning on the later of the first
day after the date which is 20 trading days after the Company files a Form 8-K
or its Form 10-K with the SEC disclosing the terms of the transactions
contemplated by this Agreement in accordance with Section 4(h) and the date on
which the Company and JFAX.COM sign a definitive merger agreement for the merger
of the Company into JFAX.COM or an affiliate of JFAX.COM on terms substantially
similar to the terms set forth in the Letter of Intent (such later date is
referred to herein as the "RESTRICTION TRIGGER DATE") and (B) ending on the
earlier of (I) the date of a Merger Termination, (II) the date which this
Agreement is terminated in accordance with Section 9(l), and (III) the date of
the consummation of the merger of the Company into JFAX.COM or an affiliate of
JFAX.COM on terms substantially similar to the same terms set forth in the
Letter of Intent, neither such Investor nor any of such Investor's affiliates
shall make Net Sales (as defined below) of the Common Stock during any calendar
month ending on or after the Restriction Trigger Date in excess of 400,000
shares of Common Stock (with partial calendar months prorated) (subject to
adjustment for stock splits, stock dividends, stock combinations and other
similar transactions). Notwithstanding the foregoing, the restrictions set forth
in the preceding sentence shall not apply on and after any date on which the
Company materially breaches any of its obligations or covenants in this
Agreement or in the Series B Certificate of Designations. For purposes of this
Section 4(s), "NET SALES" means the result of total sales of Common Stock during
a specific calendar month minus total purchases of Common Stock during such
calendar month.

           (t) Waiver and Consent Under Series A Purchase Agreement. Each
Investor waives the Company's obligations to comply with its obligations under
Sections 4(c) and 4(g) of the Series A Purchase Agreement in connection with the
Company's merger into JFAX.COM or an affiliate of JFAX.COM on substantially the
terms set forth in the Disclosure Information, provided that the Closing occurs
on or before April 14, 2000 and the Company otherwise is in compliance with its
obligations in this Agreement. Each Investor waives its rights under Sections
4(f) and 4(j) with respect to the Company's issuance of warrants to acquire
shares of Common stock to JFAX.COM pursuant to the terms set forth in the
Disclosed Information.

        5. TRANSFER AGENT INSTRUCTIONS.

           The Company shall issue irrevocable instructions to its transfer
agent, and any subsequent transfer agent, to issue certificates, registered in
the name of each Investor or its respective nominee(s), for the Conversion
Shares in such amounts as specified from time to time by each Investor to the
Company upon conversion of the Preferred Shares (the "IRREVOCABLE TRANSFER AGENT
INSTRUCTIONS"). Prior to registration of the Conversion Shares under the 1933
Act, all such certificates shall bear the restrictive legend specified in
Section 2(d) of this Agreement until such legend is permitted to be removed
pursuant to the last paragraph of Section 2(g). The Company warrants that no
instruction other than the Irrevocable Transfer Agent Instructions referred to
in this Section 5, and stop transfer instructions to give effect to Section 2(e)
(in the case of the Conversion Shares, prior to registration of the Conversion
Shares under the 1933 Act) will be given by the Company to its transfer agent
and that the Securities shall otherwise be freely transferable on the books and
records of the Company as and to the extent provided in this Agreement and the
Registration Rights Agreement. Nothing in this Section 5 shall affect in any way
each Investor's obligations and agreements set forth in Section 2(d) to comply
with all applicable prospectus delivery requirements, if any, upon resale of the
Securities. If an Investor provides the Company with an opinion of counsel, in a
form reasonably acceptable to the Company, to the effect that the public sale,
assignment or transfer of the Securities may be made without registration under
the 1933 Act or the Investor provides the Company with assurances reasonably
acceptable to the Company that the Securities can be sold pursuant to Rule 144
without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold, the Company shall permit the
transfer, and, in the case of the Conversion Shares promptly instruct its
transfer agent to issue one or more certificates in such name and in such
denominations as specified by such Investor and without any restrictive legends.
The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Investors by vitiating the intent and purpose of
the transaction contemplated hereby. Accordingly, the Company acknowledges that
the remedy at law for a breach of its obligations under this Section 5 will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Section 5, that the Investors shall be
entitled, in addition to all other available remedies, to an injunction
restraining any breach and requiring immediate issuance and transfer, without
the necessity of showing economic loss and without any bond or other security
being required.

undertaking by the Company may be unenforceable for any reason, the Company
shall make the maximum contribution to the payment and satisfaction of each of
the Indemnified Liabilities which is permissible under applicable law.

        9. GOVERNING LAW; MISCELLANEOUS.

           a. Governing Law; Jurisdiction; Jury Trial. All questions concerning
the construction, validity, enforcement and interpretation of this Agreement
shall be governed by the internal laws of the State of California, without
giving effect to any choice of law or conflict of law provision or rule (whether
of the State of California or any other jurisdictions) that would cause the
application of the laws of any jurisdictions other than the State of California.
Each party hereby irrevocably waives any right it may have, and agrees not to
request, a jury trial for the adjudication of any dispute hereunder or in
connection with or arising out of this agreement or any transaction contemplated
hereby.

           b. 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 party; 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.

           c. Headings. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Agreement.

           d. Severability. If any provision of this Agreement shall be invalid
or unenforceable in any jurisdiction, such invalidity or unenforceability shall
not affect the validity or enforceability of the remainder of this Agreement in
that jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction.

           e. Entire Agreement; Amendments. This Agreement supersedes all other
prior oral or written agreements between the Investors, the Company, their
affiliates and persons acting on their behalf with respect to the matters
discussed herein, and this Agreement and the instruments referenced herein
contain the entire understanding of the parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Investor makes any representation,
warranty, covenant or undertaking with respect to such matters. The Series A
Purchase Agreement, the Series A Warrants (as defined in the Series A Purchase
Agreement) and the Registration Rights Agreement (as defined in the Series A
Purchase Agreement) shall remain in full force and effect with respect to the
securities and the transactions contemplated thereby. No provision of this
Agreement may be amended other than

                                       20

<PAGE>   21

by an instrument in writing signed by the Company and the holders of at least
two-thirds (2/3) of the Preferred Shares then outstanding, and no provision
hereof may be waived other than by an instrument in writing signed by the party
against whom enforcement is sought. No such amendment shall be effective to the
extent that it applies to less than all of the holders of the Preferred Shares
then outstanding. No consideration shall be offered or paid to any person to
amend or consent to a waiver or modification of any provision of any of the
Transaction Documents or the Certificate of Designations unless the same
consideration also is offered to all of the parties to the Transaction Documents
or holders of Preferred Shares, as the case may be.

required or permitted to be given under the terms of this Agreement must be in

accordance with clause (i), (ii) or (iii) above, respectively.

           g. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and assigns,
including any purchasers of the Preferred Shares. The Company shall not assign
this Agreement or any rights or obligations hereunder without the prior written
consent of the holders of at least two-thirds (2/3) of the Preferred Shares then
outstanding, including by merger or consolidation, except pursuant to a Major
Corporate Event (as defined in Section 4(b) of the Series C Certificate of
Designations), provided that the Company has complied with Section 4(j) of this
Agreement with Section 4 of the Series B Certificate of Designations, with
respect to the Series B Preferred Shares, and Sections 4(a) and 4(b) of the
Series C Certificate of Designations, with respect to the Series C Preferred
Shares, if any. An Investor may assign some or all of its rights hereunder to
(i) a Permitted Transferee (as defined below) without the consent of the Company
and (ii) to a person which is not a Permitted Transferee with the prior consent
of the Company, which consent shall not be unreasonably withheld.
Notwithstanding anything to the contrary contained in the Transaction Documents,
the Investors shall be entitled to pledge the Securities in connection with a
bona fide margin account or other loan secured by such Securities. For purposes
of this Section 9(i), a "PERMITTED TRANSFEREE" shall mean (i) an Investor, (ii)
an Affiliate (as that term is defined in Rule 501(b) under the 1933 act) of an
Investor, (iii) any holder of Preferred Shares or Warrants and (iv) any
Affiliate of a holder of Preferred Shares or Warrants.

           h. No Third Party Beneficiaries. This Agreement is intended for the
benefit of the parties hereto and their respective permitted successors and
assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person (other than JFAX.COM with respect to Section 4(r) and
Section 4(s)).

           i. Survival. Unless this Agreement is terminated under Section 9(l),
the representations and warranties of the Company and the Investors contained in
Sections 2 and 3, the agreements and covenants set forth in Sections 4, 5 and 9,
and the indemnification provisions set forth in Section 8, shall survive the
Closing and each Series C Closing. Each Investor shall be responsible only for
its own representations, warranties, agreements and covenants hereunder.

           j. Publicity. The Company and each Investor shall have the right to
approve before issuance any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, that the
Company shall be entitled, without the prior

                                       22

<PAGE>   23

approval of any Investor, to make any press release or other public disclosure
with respect to such transactions as is required by applicable law and
regulations (although each Investor shall be consulted by the Company in
connection with any such press release or other public disclosure prior to its
release and shall be provided with a copy thereof).

           k. Further Assurances. Each party shall do and perform, or cause to
be done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

           l. Termination. In the event that the Closing shall not have occurred
with respect to an Investor on or before April 14, 2000 due to the Company's or
such Investor's failure to satisfy the conditions set forth in Sections 6 and 7
above (and the nonbreaching party's failure to waive such unsatisfied
condition(s)), the nonbreaching party shall have the option to terminate this
Agreement with respect to such breaching party at any time after 5:00 p.m.,
California time, on April 14, 2000 without liability of any party to any other
party. In the event that the Closing shall not have occurred with respect to an
Investor on or before April 14, 2000 due to the failure of the condition set
forth in Section 6(v), with respect to the Company, and Section 7(xv), with
respect to an Investor, to be satisfied (and such party's failure to waive such
unsatisfied condition), either the Company or any Investor shall have the option
to terminate this Agreement with respect to such party at any time after 5:00
p.m., California time, on April 14, 2000 without liability of any party to any
other party. Notwithstanding the foregoing, that if this Agreement is terminated
by the Investors pursuant to this Section 9(l), the Company shall remain
obligated to reimburse the Investors for the expenses described in Section 4(g)
above.

           m. Placement Agent. The Company acknowledges that it has not engaged
any placement agent in connection with the sale of the Preferred Shares. The
Company shall be responsible for the payment of any placement agent's fees or
broker's commissions (other than those of placement agents or brokers engaged by
an Investor) relating to or arising out of the transactions contemplated hereby.
The Company shall pay, and hold each Investor harmless against, any liability,
loss or expense (including, without limitation, attorneys' fees and out of
pocket expenses) arising in connection with any such claim. Each Investor,
severally and not jointly, represents that it has not engaged any placement
agent or broker for the exchange of the Series A Preferred Shares for the Series
B Preferred Shares.

           n. No Strict Construction. The language used in this Agreement will
be deemed to be the language chosen by the parties to express their mutual
intent, and no rules of strict construction will be applied against any party.

           o. Remedies. Each Investor and each holder of the Securities shall
have all rights and remedies set forth in the Transaction Documents and all
rights and remedies which such holders have been granted at any time under any
other agreement or contract and all of the rights which such holders have under
any law. Any person having any rights under any provision of this Agreement
shall be entitled to enforce such rights specifically (without posting a bond or
other

                                       23

<PAGE>   24

security), to recover damages by reason of any breach of any provision of this
Agreement and to exercise all other rights granted by law.

           p. Payment Set Aside. To the extent that the Company makes a payment
or payments to the Investors hereunder or pursuant to the Certificate of
Designations or the Investors enforce or exercise their rights hereunder or
thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside, recovered from, disgorged by or are
required to be refunded, repaid or otherwise restored to the Company, a trustee,
receiver or any other Person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff
had not occurred.
