conducted or as proposed to be conducted. Neither the execution nor delivery of
this Agreement, nor the carrying on of the Company's business by the employees
of the Company, nor the conduct of the Company's business, will, to the

represents and warrants to the Company as follows:

                  (a)   The Series C Preferred Shares and the Conversion Shares
issuable upon conversion thereof are being acquired for the Purchaser's own
account, for investment and not with a view to, or for resale in connection
with, any distribution or public offering thereof within the meaning of the

                  (b)   The Purchaser understands that the Series C Preferred

Act by reason of their issuance in a transaction exempt from the registration
and prospectus delivery requirements of the Securities Act pursuant to Section
4(2) thereof, that the Company has no present intention of registering the
Series C Preferred Shares or the Conversion Shares, that the Series C Preferred
Shares and the Conversion Shares must be held by the Purchaser indefinitely, and
that the Purchaser must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Securities Act or is exempt from registration. The Purchaser further understands
that the Series C Preferred Shares and the Conversion Shares have not been
qualified under the California Law by reason of their issuance in a transaction
exempt from the qualification requirements of the California Law pursuant to
Section 25102(f) thereof, which exemption depends upon, among other things, the
bona fide nature of the Purchaser's investment intent expressed above.

                  (c)   During the negotiation of the transactions contemplated
herein, the Purchaser and its representatives and legal counsel have been
afforded full and free access to

                                       9
<PAGE>   10

corporate books, financial statements, records, contracts, documents, and other
information concerning the Company and to its offices and facilities, have been
afforded an opportunity to ask such questions of the Company's officers,
employees, agents, accountants and representatives concerning the Company's
business, operations, financial condition, assets, liabilities and other
relevant matters as they have deemed necessary or desirable, and have been given
all such information as has been requested, in order to evaluate the merits and
risks of the prospective investments contemplated herein. The foregoing does not
limit or modify the representations or warranties of the Company in Section 3
hereof or the rights of the Purchaser to rely thereon.

                  (d)   The Purchaser and its representatives have been solely
responsible for the Purchaser's own "due diligence" investigation of the Company
and the Company's management and business, for its own analysis of the merits
and risks of this investment, and for its own analysis of the fairness and
desirability of the terms of the investment. In taking any action or performing
any role relative to the arranging of the proposed investment, the Purchaser has
acted solely in its own interest, and none of the Purchaser (or any of their
agents or employees) has acted as an agent of the Company or any other
Purchaser. The Purchaser has such knowledge and experience in financial and
business matters that the Purchaser is capable of evaluating the merits and
risks of the purchase of the Series C Preferred Shares pursuant to the terms of
this Agreement and of protecting Purchaser's interests in connection therewith.

                  (e)   The Purchaser has the full right, power and authority to
enter into and perform the Purchaser's obligations under this Agreement, the
Second Restated Investors Rights Agreement and the Second Restated Shareholders
Agreement, and this Agreement, the Second Restated Investors Rights and the
Second Restated Shareholders Agreement constitute valid and binding obligations
of the Purchaser enforceable in accordance with their terms except (A) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium, and
other laws of general application affecting enforcement of creditors' rights
generally, and (B) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies.

                  (f)   No consent, approval or authorization of, or
designation, declaration or filing with, any governmental authority on the part
of the Purchaser is required in connection with the valid execution and delivery
of this Agreement, the Second Restated Investors Rights Agreement and the Second
Restated Shareholders Agreement.

                  (g)   Purchaser is an "accredited investor" as defined in Rule
501 pursuant to the Securities Act.

            4.2   Legend. Each certificate representing the Series C Preferred
Shares or the Conversion Shares may be endorsed with the following legends:

                  (a)   THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE
REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE TRANSFER IS
MADE IN COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH ACT OR THE

                                       10
<PAGE>   11

COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES
REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER,
ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
DELIVERY REQUIREMENTS OF SUCH ACT.

The Company need not register a transfer of any Series C Preferred Shares or
Conversion Shares, and may also instruct its transfer agent not to register the
transfer of the Series C Preferred Shares or Conversion Shares, unless the
conditions specified in the foregoing legends are satisfied.

            4.3   Removal of Legend and Transfer Restrictions. Any legend
endorsed on a certificate pursuant to Section 4.2(a) and the stop transfer
instructions with respect to such Series C Preferred Shares or Conversion Shares
shall be removed, and the Company shall issue a certificate without such legend
to the holder thereof if (i) such Series C Preferred Shares or Conversion Shares
are registered under the Securities Act and a prospectus meeting the
requirements of Section 10 of the Securities Act is available, (ii) such legend
may be properly removed under the terms of Rule 144 promulgated under the
Securities Act or (iii) such holder provides the Company with an opinion of
counsel for such holder, reasonably satisfactory to legal counsel for the
Company, to the effect that a sale, transfer or assignment of such Series C
Preferred Shares or Conversion Shares may be made without registration.
Notwithstanding the foregoing, no such registration statement or opinion of
counsel shall be necessary for a transfer by a Purchaser to an affiliate or to
the Purchaser's family members or trust for the benefit of an individual
Purchaser and his or her family members; provided, however, that in any such
instance the transferee will be subject to the terms of this Agreement to the
same extent as if he, she or it were an original Purchaser hereunder. For the
purposes of this Section 2, an "affiliate" shall mean any officer, director,
partner (including the principals of any general partner) or shareholder of a
Purchaser or any person or entity that directly or indirectly through one or
more intermediaries controls or is controlled by or is under common control with
a Purchaser.

            4.4   Tax Consequences. Purchaser has reviewed with its own tax
advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. Purchaser
understands that Purchaser (and not the Company) shall be responsible for
Purchaser's own tax liability that may arise as a result of this investment or
the transactions contemplated by this Agreement.

      5.    Conditions to Closing.

            5.1   Conditions to Obligations of the Purchaser. The obligation of
Purchaser to purchase Series C Preferred Shares at the Closing is subject to the
fulfillment on or prior to the Closing Date of the following conditions, any of
which may be waived by the Purchaser:

                  (a)   Accuracy of Representations and Warranties; Performance
of Obligations. The representations and warranties made by the Company in
Section 3 above shall be true and correct when made, and shall be true and
correct in all material respects on the Closing Date with the same force and
effect as if they had been made on and as of said date; the Company's business
and assets shall not have been adversely affected in any material way prior to
the Closing Date; and the Company shall have performed all obligations and
conditions herein required to be performed or observed by it on or prior to the
Closing Date.

shall have executed and delivered the Second Restated Shareholders Agreement in
the form attached hereto as Exhibit E (the "Second Restated Shareholders

            5.2   Conditions to Obligations of the Company. The Company's
obligation to sell and issue the Series C Preferred Shares at the Closing is
subject to the fulfillment on or prior to the Closing Date of the following
conditions, any of which may be waived by the Company:

                  (a)   Accuracy of Representations and Warranties. The
representations and warranties made by Purchaser in Section 4 hereof shall be
true and correct in all material respects when made, and shall be true and

made on and as of said date.

                  (b)   Incorporation of Conditions. The conditions set forth in

<PAGE>   13

Company (which consent shall not be unreasonably withheld).

            6.2   Waivers and Amendments. With the written consent of the
Company and the record or beneficial holders of at least sixty percent (60%) of
the Series C Preferred Shares issued pursuant to this Agreement (including any
Conversion Shares, shares issued in exchange for the Series C Preferred Shares
or Conversion Shares and as adjusted for stock dividends, stock splits,
recapitalization and the like), the obligations of the Company and the rights of
the holders of the Series C Preferred Shares under this Agreement may be waived
(either generally or in a particular instance, either retroactively or
prospectively and, either for a specified period of time or indefinitely), and
with the same consent the Company, when authorized by resolution of the Board of
Directors, may enter into a supplementary agreement for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement; provided, however, that no such waiver or supplemental
agreement shall reduce the aforesaid percentage of Series C Preferred Shares,
the holders of which are required to consent to any waiver or supplemental
agreement without the consent of the record or beneficial holders of all of the
Series C Preferred Shares; and provided further, however, that if such

Directors including Cliff Young. Upon the effectuation of each such waiver,

respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

                   SERIES D PREFERRED STOCK PURCHASE AGREEMENT

        THIS SERIES D PREFERRED STOCK PURCHASE AGREEMENT (this "Agreement") is
entered into as of April 13, 2000, by and among ICNT, Inc., a California
corporation (the "Company"), and each of the undersigned purchasers of Series D
Preferred Stock of the Company (each, a "Purchaser," and collectively, the
"Purchasers") listed on the Schedule of Purchasers attached hereto as Exhibit A.

        In consideration for and of the mutual promises, covenants and
conditions hereinafter set forth and other good and valuable consideration the
receipt and sufficiency of which are hereby acknowledged, the parties hereby
agree as follows:

        1. Authorization and Sale of the Shares.

               1.1. Authorization; Amended and Restated Articles of
Incorporation. The Company has authorized the issuance and sale pursuant to the
terms and conditions hereof of up to Six Million Two Hundred Sixty Thousand
Eight Hundred Twenty Three (6,260,823) shares of its Series D Preferred Stock
(the "Series D Preferred Shares"), having the rights, preferences, privileges
and restrictions as set forth in the form of Amended and Restated Articles of
Incorporation of the Company (the "Restated Articles") attached hereto as
Exhibit B.

               1.2. Issuance and Sale. Subject to the terms and conditions set
forth in this Agreement, each Purchaser agrees, severally and not jointly, to
purchase from the Company, and the Company agrees to sell and issue to each
Purchaser, severally and not jointly, at the Closing the respective number of
Series D Preferred Shares set forth opposite each Purchaser's name on Exhibit A
hereto at a purchase price of $8.52124 per share. The Series D Preferred Shares
will have the rights, preferences, privileges and restrictions set forth in the
Restated Articles.

        2. Closing; Delivery.

               2.1. Closing. The closing of the purchase and sale of the Series
D Preferred Shares hereunder (the "Closing") shall take place at the offices of
Kirkpatrick & Lockhart LLP, counsel to the Company ("K&L"), 9100 Wilshire

               2.2. Delivery. Subject to the terms and conditions set forth in
this Agreement, at the Closing the Company will deliver to each Purchaser a
stock certificate representing the number of Series D Preferred Shares set forth
beside such Purchaser's name on Exhibit A hereto, against delivery by each
Purchaser of payment of the purchase price therefor by check or wire transfer
payable to the Company, by cancellation of outstanding indebtedness of the
Company to such Purchaser, or a combination thereof in the amount specified
opposite such Purchaser's name on Exhibit A hereto. In the event that payment by
a Purchaser is made, in whole or in part, by cancellation of indebtedness, then
such Purchaser shall surrender to the Company for cancellation at the Closing
any evidence of such indebtedness or shall execute an instrument of cancellation
in form and substance acceptable to the Company. In addition, the Company at the
Closing shall deliver to any Purchaser choosing to pay any part of the purchase
price of the

Series D Preferred Shares by cancellation of indebtedness, a check in the amount
of any interest accrued on such indebtedness through the Closing Date.

        3. Representations and Warranties of the Company. Except as set forth on
Exhibit C attached hereto and incorporated herein by reference, the Company
hereby represents and warrants to each Purchaser as follows:

               3.1. Organization; Good Standing; Qualification. The Company is a
corporation duly organized and validly existing under, and by virtue of, the
laws of the State of California and is in good standing under such laws. The
Company has the requisite corporate power to own and operate its properties and
assets, and to carry on its business as presently conducted and as proposed to
be conducted. The Company is in good standing and qualified to do business as a
foreign corporation in California and in every other jurisdiction where the
failure to so qualify would have a material adverse impact on the Company's
business, properties, financial condition or results of operations. The Company
has furnished to special counsel to the Purchasers true and complete copies of
its Amended and Restated Articles of Incorporation (the "Restated Articles") and
Bylaws, each as amended to date and presently in effect.

               3.2. Corporate Power. The Company has all requisite legal and
corporate power and authority to enter into this Agreement, the Third Restated
Investors Rights Agreement and the Third Restated Shareholders Agreement, and to
sell the Series D Preferred Shares hereunder and to carry out and perform its
obligations under the terms of this Agreement, the Third Restated Investors
Rights Agreement and the Third Restated Shareholders Agreement.

               3.3. Subsidiaries. The Company does not control, directly or
indirectly, or have an interest in, any other corporation, association or
business entity.

               3.4. Capitalization.

accounts for all taxes, assessments and governmental charges with respect to its
business and operation for such subsequent period. The Company has withheld or
collected from each payment made to its employees all taxes required to be
withheld or collected therefrom, and has paid the same to the proper tax
receiving officers or authorized depositories.

directly or indirectly, interested in any contract with the Company. No officer
or director, or, to the Company's knowledge, no employee or shareholder of the
Company or any member of any officer's, director's, employee's or stockholder's
immediate family, has any direct or indirect ownership interest in any firm or
corporation with which the Company is affiliated or with which the Company has a
material business relationship, or any firm or corporation that competes with
the Company, except that employees, shareholders, officers and directors of the
Company may own stock in publicly traded companies that compete with the
Company.

liabilities, and obligations under contracts and commitments, incurred in the
ordinary course of business that are not required under generally accepted
accounting principles to be reflected in the Financial Statements and which, in
the aggregate, are not material to the financial condition or operating results
of the Company. The Company maintains and will continue to maintain a standard
system of accounting established and administered in accordance with generally
accepted accounting principles. All of the assets of the Company included on the
Balance Sheet are productively used in the conduct of the Company's business.

Transfer Imposed by the Securities Act and California Law.

               4.1. Representations and Warranties by Each Purchaser. Each
Purchaser, severally and not jointly, hereby represents and warrants to the
Company as follows:

                      (a) The Series D Preferred Shares and the Conversion
Shares issuable upon conversion thereof are being acquired for the Purchaser's
own account, for investment and not with a view to, or for resale in connection
with, any distribution or public offering thereof within the meaning of the
Securities Act or the California Law.

                      (b) The Purchaser understands that the Series D Preferred
Shares and the Conversion Shares have not been registered under the Securities
Act by reason of their issuance in a transaction exempt from the registration
and prospectus delivery requirements of the Securities Act pursuant to Section
4(2) thereof, that the Company has no present intention of registering the
Series D Preferred Shares or the Conversion Shares, that the Series D Preferred
Shares and the Conversion Shares must be held by the Purchaser indefinitely, and
that the Purchaser must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Securities Act or is exempt from registration. The Purchaser further understands
that the Series D Preferred Shares and the Conversion Shares have not been
qualified under the California Law by reason of their issuance in a transaction
exempt from the qualification requirements of the California Law pursuant to
Section 25102(f) thereof, which exemption depends upon, among other things, the
bona fide nature of the Purchaser's investment intent expressed above.

                      (c) During the negotiation of the transactions
contemplated herein, the Purchaser and its representatives and legal counsel
have been afforded full and free access to corporate books, financial
statements, records, contracts, documents, and other information concerning the
Company and to its offices and facilities, have been afforded an opportunity to
ask such questions of the Company's officers, employees, agents, accountants and
representatives concerning the Company's business, operations, financial
condition, assets, liabilities and other relevant matters as they have deemed
necessary or desirable, and have been given all such information as has been
requested, in order to evaluate the merits and risks of the prospective
investments contemplated herein. The foregoing does not limit or modify the
representations or warranties of the Company in Section 3 hereof or the rights
of the Purchaser to rely thereon.

<PAGE>   10
                      (d) The Purchaser and its representatives have been solely
responsible for the Purchaser's own "due diligence" investigation of the Company
and the Company's management and business, for its own analysis of the merits
and risks of this investment, and for its own analysis of the fairness and
desirability of the terms of the investment. In taking any action or performing
any role relative to the arranging of the proposed investment, the Purchaser has
acted solely in its own interest, and none of the Purchasers (or any of their
agents or employees) has acted as an agent of the Company or any other
Purchaser. The Purchaser has such knowledge and experience in financial and
business matters that the Purchaser is capable of evaluating the merits and
risks of the purchase of the Series D Preferred Shares pursuant to the terms of
this Agreement and of protecting Purchaser's interests in connection therewith.

                      (e) The Purchaser has the full right, power and authority
to enter into and perform the Purchaser's obligations under this Agreement, the
Third Restated Investors Rights Agreement and the Third Restated Shareholders
Agreement, and this Agreement, the Third Restated Investors Rights Agreement and
the Third Restated Shareholders Agreement constitute valid and binding
obligations of the Purchaser enforceable in accordance with their terms except
(A) as limited by applicable bankruptcy, insolvency, reorganization, moratorium,
and other laws of general application affecting enforcement of creditors' rights
generally, and (B) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies.

                      (f) No consent, approval or authorization of, or
designation, declaration or filing with, any governmental authority on the part
of the Purchaser is required in connection with the valid execution and delivery
of this Agreement, the Third Restated Investors Rights Agreement or the Third
Restated Shareholders Agreement.

                      (g) Purchaser is an "accredited investor" as defined in
Rule 501 pursuant to the Securities Act.

               4.2. Legend. Each certificate representing the Series D Preferred
Shares or the Conversion Shares may be endorsed with the following legends:

                      (a) THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE
REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE TRANSFER IS
MADE IN COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH ACT OR THE COMPANY
RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY
SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR
HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY
REQUIREMENTS OF SUCH ACT.

shall issue a certificate without such legend to the holder thereof if (i) such
Series D Preferred Shares or Conversion Shares are registered under the
Securities Act and a prospectus meeting the requirements of Section 10 of the
Securities Act is available, (ii) such legend may be properly removed under the
terms of Rule 144 promulgated under the Securities Act or (iii) such holder
provides the Company with an opinion of counsel for such holder, reasonably
satisfactory to legal counsel for the Company, to the effect that a sale,
transfer or assignment of such Series D Preferred Shares or Conversion Shares
may be made without registration. Notwithstanding the foregoing, no such
registration statement or opinion of counsel shall be necessary for a transfer
by a Purchaser to an affiliate or to the Purchaser's family members or trust for
the benefit of an individual Purchaser and his or her family members; provided,
however, that in any such instance the transferee will be subject to the terms
of this Agreement to the same extent as if he, she or it were an original
Purchaser hereunder. For the purposes of this Subsection 4.3, an "affiliate"
shall mean any officer, director, partner (including the principals of any
general partner) or shareholder of a Purchaser or any person or entity that
directly or indirectly through one or more intermediaries controls or is
controlled by or is under common control with a Purchaser.

               4.4. Tax Consequences. Purchaser has reviewed with its own tax
advisors the federal, state, local and foreign tax consequences of this
investment and the transactions contemplated by this Agreement. Purchaser
understands that Purchaser (and not the Company) shall be responsible for
Purchaser's own tax liability that may arise as a result of this investment or
the transactions contemplated by this Agreement.

        5. Conditions to Closing.

               5.1. Conditions to Obligations of the Purchasers. The obligation
of each Purchaser to purchase Series D Preferred Shares at the Closing is
subject to the fulfillment on or prior to the Closing Date of the following
conditions, any of which may be waived by the Purchasers participating in that
Closing pursuant to the terms of subsection 6.2 hereof:

                      (a) Accuracy of Representations and Warranties;
Performance of Obligations. The representations and warranties made by the
Company in Section 3 above shall be true and correct when made, and shall be
true and correct in all material respects on the Closing Date with the same
force and effect as if they had been made on and as of said date; the Company's
business and assets shall not have been adversely affected in any material way
prior to the Closing Date; and the Company shall have performed all obligations
and conditions herein required to be performed or observed by it on or prior to
the Closing Date.

                      (b) Consents and Waivers. The Company shall have obtained
any and all consents (including all governmental or regulatory consents,
approvals or authorizations required in connection with the valid execution and
delivery of this Agreement, the Third Restated Investors Rights Agreement and
the Third Restated Shareholders Agreement), permits and waivers necessary or
appropriate for consummation of the transactions contemplated in this Agreement,
the Third Restated Investors Rights Agreement and the Third Restated
Shareholders Agreement.

                      (c) Legal Investment. At the time of the Closing, the
purchase of the Series D Preferred Shares by the Purchasers hereunder shall be
legally permitted by all laws and regulations to which the Purchasers and the
Company are subject.

form and content reasonably satisfactory to Purchasers and their special
counsel.

                      (e) Restated Articles. The Restated Articles shall have
been filed with the California Secretary of State.

                      (f) Third Restated Shareholders Agreement. The Company,
the Founder (as defined in this Agreement), the holders of shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock and each
Purchaser shall have executed and delivered the Third Restated Shareholders
Agreement in the form attached hereto as Exhibit E (the "Third Restated
Shareholders Agreement").

                      (g) Third Restated Investors Rights Agreement. The
Company, the holders of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock and each Purchaser shall have executed and delivered

                      (h) Compliance Certificate. The Company shall have

subject to the fulfillment on or prior to the Closing Date of the following
conditions, any of which may be waived by the Company:

                      (a) Accuracy of Representations and Warranties. The
representations and warranties made by each Purchaser in Section 4 hereof shall
be true and correct in all material respects when made, and shall be true and
correct on the Closing Date with the same force and effect as if they had been
made on and as of said date.

                      (b) Incorporation of Conditions. The conditions set forth
in subsections (b), (c) and (e) of subsection 5.1 above shall have been
fulfilled.

        6. Miscellaneous.

               6.1. Indemnification. The Company will indemnify and defend each
Purchaser and each of its officers, directors and partners, and each person
controlling such Purchaser, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereto) arising out of any breach by the
Company of this Agreement, the Third Restated Investors Rights Agreement or the
Third Restated Shareholders Agreement; provided, however, that the indemnity
agreement contained in this subsection 6.1 shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld).

               6.2. Waivers and Amendments. With the written consent of the
Company and the record or beneficial holders of at least sixty percent (60%) of
the Series D Preferred Shares issued pursuant to this Agreement (including any
Conversion Shares, shares issued in exchange for the Series D Preferred Shares
or Conversion Shares and as adjusted for stock dividends, stock splits,
recapitalization and the like), the obligations of the Company and the rights of
the holders of the Series D Preferred Shares under this Agreement may be waived
(either generally or in a

                                       12

<PAGE>   13
particular instance, either retroactively or prospectively and, either for a
specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of the Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such waiver or supplemental agreement shall reduce
the aforesaid percentage of Series D Preferred Shares, the holders of which are
required to consent to any waiver or supplemental agreement without the consent
of the record or beneficial holders of all of the Series D Preferred Shares; and
provided further, however, that if such supplementary agreement increases the
rights of the Series D Preferred Shares, the consent of the Company shall mean
the approval of the Company's Board of Directors including Cliff Young. Upon the
effectuation of each such waiver, consent or agreement of amendment or
modification, the Company shall promptly give written notice thereof to the
record holders of the Series D Preferred Shares who have not previously
consented thereto in writing. Neither this Agreement nor any provision hereof
may be changed, waived, discharged or terminated orally, but only by a statement
in writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought, except to the extent provided in this
subsection 6.2.

               6.3. Governing Law. This Agreement shall be governed in all
respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

               6.4. California Corporate Securities Law. THE SALE OF THE
SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH
THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF
SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION
THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL UNLESS AN EXEMPTION FROM SUCH
QUALIFICATION IS AVAILABLE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE
EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, OR SUCH EXEMPTION
BEING AVAILABLE.

               6.5. Survival. The representations, warranties, covenants and
agreements made herein shall survive the execution of this Agreement and the
Closing of the transactions contemplated herein for a period of three (3) years.

               6.6. Successors and Assigns. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto. The Company may not assign this Agreement.

               6.7. Entire Agreement. This Agreement, the exhibits to this
Agreement, the Third Restated Investors Rights Agreement and the Third Restated
Shareholders Agreement constitute the full and entire understanding and
agreement between the parties with regard to the subjects hereof and thereof.

               6.8. Notices, etc. All notices and other communications required
or permitted hereunder shall be in writing and shall be sent via facsimile,
overnight courier service or mailed by certified or registered mail, postage
prepaid, return receipt requested, addressed or sent (a) if to a Purchaser, at

                                       13

<PAGE>   14
furnished to the Company in writing, or (b) if to the Company, at 4499 Glencoe
Avenue, Marina del Rey, California 90292, facsimile: (310) 881-6223, or at such
other address or number as the Company shall have furnished to the Purchasers in
writing. All notices shall be effective upon (i) delivery if sent by facsimile
(with a confirming receipt); (ii) delivery if delivered in person or sent by
overnight courier service or (iii) three (3) days after deposit in the U.S.
mail, registered or certified, with postage prepaid and properly addressed
according to this Subsection 6.8.

               6.9. Severability. In case any provision of this Agreement shall
be declared invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

               6.10. Finder's Fees.

                      (a) The Company (i) represents and warrants that it has
retained no finder or broker in connection with the transactions contemplated by
this Agreement and (ii) hereby agrees to indemnify and to hold the Purchasers
harmless of and from any liability for any commission or compensation in the
nature of a finder's fee to any broker or other person or firm (and the costs
and expenses of defending against such liability or asserted liability) for
which the Company, or any of its employees or representatives, are responsible.

                      (b) Each Purchaser (i) represents and warrants that it has
retained no finder or broker in connection with the transactions contemplated by
this Agreement and (ii) hereby agrees to indemnify and to hold the Company and
the other Purchasers harmless of and from any liability for any commission or
compensation in the nature of a finder's fee to any broker or other person or
firm (and the costs and expenses of defending against such liability or asserted
liability) for which it, or any of its employees or representatives, are
responsible.

               6.11. Expenses. The Company and each Purchaser shall each bear
its respective expenses and legal fees incurred with respect to this Agreement
and the transactions contemplated herein.

               6.12. Titles and Subtitles. The titles of the paragraphs and
subparagraphs of this Agreement are for convenience of reference only and are
not to be considered in construing this Agreement.

               6.13. Counterparts. This Agreement may be executed in any number
of counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

               6.14. Delays or Omissions. No delay or omission to exercise any
right, power or remedy accruing to any Purchaser, upon any breach or default of
the Company under this Agreement, shall impair any such right, power or remedy,
nor shall it be construed to be a waiver of any such breach or default, or any
acquiescence therein, or of or in any similar breach or default thereafter
occurring; nor shall any waiver of any single breach or default be deemed a
waiver of any other breach or default theretofore or thereafter occurring. It is
further agreed that any waiver, permit, consent or approval of any kind or
character on a Purchaser's part of any breach or default under this Agreement,
or any waiver on a Purchaser's part of any provisions or conditions of this
Agreement must be in writing and shall be effective only to the extent
specifically set forth in such writing and that all remedies, either under this
Agreement, or by law or otherwise afforded to a Purchaser, shall be cumulative
and not alternative.
