employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
such employee's duties to the Company or that would conflict with the Company's
business as now 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 Company's knowledge, conflict with or result in a material breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any employee is now obligated. The Company is
not utilizing and it will not be necessary for the Company to utilize any

adversely affect the business, properties, financial condition and results of
operations of the Company. The execution, delivery and performance of and
compliance with this Agreement, the Investors Rights Agreement and the
Shareholders Agreement and the transactions contemplated herein and therein will
not result in (a) any such violation and will not be in conflict with or

employment contract, patent disclosure agreement or any other contract or
agreement relating to the right of any such employee to be employed by the
Company or to serve as a consultant because of the nature of the business
conducted or to be conducted by the Company or for any other reason, and the
continued employment or use by the Company of its present employees and
consultants will not result in any such violations. The Company has no deferred
compensation, pension, profit sharing, bonus, insurance, severance or any other
similar employee benefit plan or obligation or any employment or severance
agreement covering any of its officers or employees. There are no asserted
controversies or labor disputes or union organization activities pending or, to

impairment of the right or ability of the Company to carry on its business as
now conducted or as proposed to be conducted, or in any material liability on
the part of the Company, and none which questions the validity of this
Agreement, the Investors Rights Agreement or the Shareholders Agreement, or any

Investors Rights Agreement, (iii) the Shareholders Agreement and (iv) the
projections of the Company dated June 2, 1999 previously delivered to the

taxes shown thereon to be due have been timely paid with exceptions not material

amended (the "Code"), that the Company be taxed as an S Corporation or (b)

Company has made adequate provisions on its books and 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.

              3.16 Transactions with Principals. No employee, shareholder,

loans or extend or guarantee credit) to any of them other than (a) for payment
of salary for services rendered, (b) reimbursement for reasonable expenses
incurred on behalf of the Company, and (c) for other standard employee benefits
made generally available to all employees (including stock option agreements
outstanding under the Stock Option Plan and approved by the Board of Directors).
No officer or director, and, to the Company's knowledge, no other person is,
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

the Interim Financial Statements, to normal year-end adjustments and except that
the Interim Financial Statements may not contain footnotes. Since December 31,
1998, there has been no change in any accounting policies, principles, methods
or practices. Except as set forth in the Financial Statements, the Company has
no liabilities, contingent or otherwise, other than 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. The Company has not
capitalized any of its research and development expenses.

such franchises, permits, licenses or similar authority held by the Company.

        4. Representations and Warranties of Purchasers and Restrictions on
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 A 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 A 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 A Preferred Shares or the Conversion Shares, that the Series A 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 A 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



                                       10
<PAGE>   11

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 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 A 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
Investors Rights Agreement and the Shareholders Agreement, and this Agreement,
Investors Rights Agreement and the 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 Investors Rights Agreement or the 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 A 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,

                                       11
<PAGE>   12

        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 A Preferred Shares or
Conversion Shares, and may also instruct its transfer agent not to register the
transfer of the Series A 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 A 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 A 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 A 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 Purchasers. The obligation of
each Purchaser to purchase Series A Preferred Shares at the Closing is subject

Agreement), permits and waivers necessary or appropriate for consummation of the
transactions contemplated in this Agreement, the Investors Rights Agreement and
the Shareholders Agreement.

                     (f) Shareholders Agreement. The Company, the Founder (as

the Shareholders Agreement in the form attached hereto as Exhibit D (the
"Shareholders Agreement").

                     (g) Investors Rights Agreement. The Company and each
Purchaser shall have executed and delivered the Investors Rights Agreement in
the form attached hereto as Exhibit E.

                     (h) Restricted Stock Purchase Agreement. The Company and

<PAGE>   14

              5.2 Conditions to Obligations of the Company. The Company's
obligation to sell and issue the Series A 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 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 Investors Rights Agreement or the 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 A Preferred Shares issued pursuant to this Agreement (including any
Conversion Shares), shares issued in exchange for the Series A 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 A 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 A 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 A Preferred Shares; and provided further, however, that if such
supplementary agreement increases the rights of the Series A 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 A Preferred
Shares who have not previously consented thereto in writing. Neither this
Agreement nor any provision



                                       14
<PAGE>   15

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 Investors Rights Agreement and the Shareholders Agreement
constitute the full and entire understanding and agreement between the parties
with regard to the subjects hereof and thereof.

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 Section 6.8.

              6.9 Separability. In case any provision of this Agreement shall be
declared invalid,



                                       15
<PAGE>   16

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; provided, however, that the Company will
pay the legal fees and expenses of one special counsel for the Purchasers and
other third party expenses up to a maximum of $30,000.

              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.
