majority of the full Board of Directors of the Company and, thereupon, a copy
of such budget promptly shall be sent to the Investors. The Company shall

the Investors of all changes therein and all material deviations therefrom.

         The Company will, upon reasonable prior notice to the Company,
permit authorized representatives of the Investors to visit and inspect any
of the properties of the Company and its subsidiaries, including its books of

associated with any other work on behalf of the Company.

                  5.4      CONDUCT OF BUSINESS. The Company will continue to

Company will pay and discharge all lawful taxes, assessments and governmental
charges or levies imposed upon it or upon its income or property before the
same shall become in default, as well as all lawful claims for labor,
materials and supplies which, if not paid when due, might become a lien or
charge upon its property or any part thereof; provided, however, that the
Company shall not be required to pay and discharge any such tax, assessment,
charge, levy or claim so long as the validity thereof is being contested by
the Company in good faith by appropriate proceedings and an adequate reserve
therefor has been established on its books. The Company will comply with all
applicable laws and regulations in the conduct of its business, including,
without limitation, all applicable federal and state securities laws in
connection with the issuance of any shares of its capital stock.

                  5.7      INSURANCE. The Company will keep its insurable
properties insured, upon reasonable business terms, by financially sound and

customarily maintained by companies in the same or similar business as the
Company. The Company will also maintain with such insurers insurance against
other hazards and risks and liability to persons and property to the extent
and in the manner customary for companies engaged in the same or similar
business.

                  5.8      KEY PERSON INSURANCE. The Company will use its
best efforts to maintain the coverage under the "key person" term life

promptly advise the Investors of any event which represents or is reasonably
likely to result in a material adverse change in the condition (financial or
otherwise), business or prospects of the Company and its subsidiaries, and of
each suit or proceeding commenced or threatened against the Company or any of
its subsidiaries which, if adversely determined, in the reasonable judgment
of the Company, is reasonably likely to have a material adverse effect on the
Company and its subsidiaries or their condition (financial or otherwise),
business or prospects.

                  5.11     STOCK GRANTS. The Company and its subsidiaries

foregoing, the Company shall take all action necessary or appropriate to
remove promptly any impediment to the redemption of the Preferred Shares or
the Redeemable Preferred Stock as contemplated by the Amended and Restated
Articles of Incorporation. For purposes of this Section 5.17, Senior Debt

company or other institutional lender providing financing to the Company.

                  5.18     NO AMENDMENTS TO ARTICLES OF INCORPORATION. Except
as contemplated by Section 5.21 below, the Company will not make any

<PAGE>

stated therein or necessary in order to make the statements therein not false

         SECTION 6.          TERMINATION

two-thirds in interest of the Investors (the "Majority Investors");

                  (b)      by either the Company or the Majority Investors if
the Stock Redemption Agreement has been terminated;

                  (c)      by either the Company or the Majority Investors if

         SECTION 7.          GENERAL

                  7.1      AMENDMENTS WAIVERS AND CONSENTS. For the purposes of
this Agreement and all agreements executed pursuant hereto, no course of dealing
between or among any of the parties hereto and no delay on the part of any party
hereto in exercising any rights hereunder or thereunder shall operate as a
waiver of the rights hereof and thereof. No provision


                                      11

<PAGE>

hereof may be waived otherwise than by a written instrument signed by the
parties so waiving such covenant or other provision; provided, however, in
the case of the Investors, changes in or additions to, and any consents or
waivers given pursuant to, this Agreement may be made, and compliance with
any term, covenant, condition or provision set forth herein may be omitted or
waived (either generally or in a particular instance and either retroactively
or prospectively) by a consent of the Investors in accordance with Section
7.2. Any amendment or waiver effected in accordance with this Section 7.1
shall be binding upon each holder of Preferred Shares or Conversion Shares at
the time outstanding, each future holder of all such securities and the
Company and each of their assigns.

                  7.2      ACTIONS OR CONSENTS OF INVESTORS. Any actions
required to be taken or consents, approvals, votes or waivers required or
contemplated to be given by the Investors shall require a vote of

Preferred Shares or Conversion Shares at the relevant time.

                  7.3      INDEMNIFICATION FROM THE COMPANY: EXPENSES.

                  (a)      Without limitation of any other provision of this
Agreement, the Company agrees to defend, indemnify and hold the Investors and
their affiliates and their respective direct and indirect partners, members,
Stockholders, directors, officers, employees and agents and each person who
controls any of them within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act of 1934, as amended (the "Exchange Act")
(parties receiving the benefit of the indemnification agreement herein shall
be referred to collectively as "Indemnified Parties" and individually as an
"Indemnified Party") harmless from and against any and all losses, claims,
damages, obligations, liens, assessments, judgments, fines, liabilities, and
other costs and expenses (including without limitation interest, penalties
and any investigation, reasonable, legal and accountant fees and other
expenses incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding or any claim asserted, as the same are
incurred) of any kind or nature whatsoever which may be sustained or suffered
by any such Indemnified Party, without regard to any investigation by any of
the Indemnified Parties, based upon, arising out of, by reason of or
otherwise in respect of or in connection with (i) any breach of any covenant
or agreement made by the Company in this Agreement or in any agreement or
instrument delivered pursuant to or in connection with this Agreement, or of
(ii) their status as a securityholder, creditor, director, agent,
representative or controlling person of the Company (including, without
limitation, any and all Losses under the Securities Act, the Exchange Act or
other federal or state statutory law or regulation, at common law or
otherwise, which relates directly or indirectly to the registration,
purchase, sale or ownership of any securities of the Company or to any
fiduciary obligation owed with respect thereto), including without limitation
in connection with any third party or governmental action or claim relating
to any action taken or omitted to be taken or alleged to have been taken or
omitted to have been taken by any Indemnified Party as shareholder, director,
agent, representative or controlling person of the Company or otherwise,
alleging so-called control person liability or securities law liability;
provided, however, that the Company will not be liable to the extent that
such loss, claim, damage, expense or liability arises from and is based on
(A) an untrue statement or omission or alleged untrue statement or omission
in a registration statement or prospectus which is made in reliance on and in
conformity with written information furnished to the Company in an instrument
duly executed by or on behalf of such Indemnified Party specifically stating
that it


                                      12

<PAGE>

is for use in the preparation thereof or (B) a knowing and willful violation
of the federal securities laws by an Indemnified Party, as finally determined
by a court of competent jurisdiction.

                  (b)      If the indemnification provided for in Section
7.3(a) above for any reason is held by a court of competent jurisdiction to
be unavailable to an Indemnified Party in respect of any losses, claims,
damages, expenses or liabilities referred to therein, then the Company, in
lieu of indemnifying such Indemnified Party thereunder, shall contribute to
the amount paid or payable by such Indemnified Party as a result of such
losses, claims, damages, expenses or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Investors, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company and the Investors in connection with the action
or inaction which resulted in such losses, claims, damages, expenses or
liabilities, as well as any other relevant equitable considerations. In
connection with any registration of the Company's securities, the relative
benefits received by the Company and the Investors shall be deemed to be in
the same respective proportions that the net proceeds from the offering
(before deducting expenses) received by the Company and the Investors, in
each case as set forth in the table on the cover page of the applicable
prospectus, bear to the aggregate public offering price of the securities so
offered. The relative fault of the Company and the Investors shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company or the
Investors and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

         The Company and the Investors agree that it would not be just and
equitable if contribution pursuant to this Section 7.3(b) were determined by
pro rata or per capita allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in the
immediately preceding paragraph. In connection with the registration of the
Company's securities, in no event shall an Investor be required to contribute
any amount under this Section 7.3(b) in excess of the lesser of (i) that
proportion of the total of such losses, claims, damages or liabilities
indemnified against equal to the proportion of the total securities sold
under such registration statement which is being sold by such Investor or
(ii) the proceeds received by such Investor from its sale of securities under
such registration statement. No person found guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not found guilty of
such fraudulent misrepresentation.

                  (c)      The indemnification and contribution provided for
in this Section 6.3 will remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Parties or any officer,
director, partner, employee, agent or controlling person of the Indemnified
Parties.

                  (d)      The provisions of this Section 7.3 are in addition
to and shall supplement those set forth in the Stockholders' Agreement which
shall apply in the case of the


                                      13
<PAGE>

registration and sale of Registrable Securities held by any of the Investors
registered as provided in the Stockholders' Agreement.

                  (e)      The Company agrees to pay and hold the Investors
harmless against liability for payment of all reasonable out-of-pocket costs
and expenses incurred in connection with their ongoing investment in the
Company, including without limitation the fees and disbursements of counsel
and other professionals and any costs and expenses associated with the
performance and enforcement of this Agreement and the agreements, documents
and instruments contemplated hereby or executed pursuant hereto. In addition,
the Company agrees to pay any and all stamp, transfer and other similar taxes
(together in each case with interest and penalties, if any) payable or
determined to be payable in connection with the execution and delivery of
this Agreement and the issuance of securities hereunder.

                  7.4      SURVIVAL OF REPRESENTATIONS; ASSIGNABILITY OF
RIGHTS; NO THIRD PARTY BENEFICIARIES. All representations, warranties,
covenants and agreements of the Company made herein and in the certificates,
exhibits and schedules delivered to any Investor in connection herewith (a)
are material and shall be deemed to have been relied upon by such Investor,
and shall survive the delivery of the Securities and (b) shall bind the
Company's successors and assigns, whether so expressed or not, and, except as
otherwise provided in this Agreement, all such covenants, agreements,
representations and warranties shall inure to the benefit of the Investors'
successors and assigns and to transferees of the Securities, whether so
expressed or not, with any such assignee (and any successive assignee
thereof) being deemed an "Investor" for purposes hereof. Nothing in this
Agreement, express or implied, is intended to confer upon any person other
than the parties hereto or their respective successors and assigns, any
rights, remedies, obligations or liabilities under or by reason of this
Agreement.

                  7.5      GOVERNING LAW. This Agreement shall be deemed to
be a contract made under, and shall be construed in accordance with, the laws
of California, without giving effect to conflict of laws principles thereof.

                  7.6      SECTION HEADINGS AND GENDER. The descriptive
headings in this Agreement have been inserted for convenience only and shall
not be deemed to limit or otherwise affect the construction of any provision
thereof or hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or
neuter, and vice versa, as the context may require.

                  7.7      COUNTERPARTS. This Agreement may be executed
simultaneously in any number of counterparts, each of which when so executed
and delivered shall be taken to be an original; but such counterparts shall
together constitute but one and the same document.

                  7.8      NOTICES AND DEMANDS. Any notice or demand which is
required or provided to be given under this Agreement shall be deemed to have
been sufficiently given and received for all purposes when delivered by hand,
telecopy, telex or other method of facsimile, or five (5) days after being
sent by certified or registered mail, postage and charges prepaid, return
receipt requested, or two (2) days after being sent by overnight delivery
providing receipt of delivery, to the addresses shown on the signature page
hereof or on EXHIBIT A hereto or at any


                                      14

<PAGE>

other address designated by such Investor to the Company; and if to an
assignee of an Investor, at its address as designated to the Company and the
other Investors in writing.

                  7.9      DISPUTE RESOLUTION. Except with respect to matters
as to which injunctive relief is being sought, any dispute arising out of or
relating to this Agreement that has not been settled within thirty (30) days
by good faith negotiation between the parties to this Agreement shall be
submitted for final and binding arbitration pursuant to the commercial
arbitration rules of the American Arbitration Association. Any such
arbitration shall be conducted in San Francisco, California.

                  7.10     REMEDIES; SEVERABILITY. Notwithstanding Section
7.9, it is specifically understood and agreed that any breach of the
provisions of this Agreement by any person subject hereto will result in
irreparable injury to the other parties hereto, that the remedy at law alone
will be an inadequate remedy for such breach, and that, in addition to any
other legal or equitable remedies which they may have, such other parties may
enforce their respective rights by actions for specific performance (to the
extent permitted by law). Whenever possible, each provision of this Agreement
shall be interpreted in such a manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be deemed
prohibited or invalid under such applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, and such
prohibition or invalidity shall not invalidate the remainder of such
provision or the other provisions of this Agreement.

                  7.11     INTEGRATION. This Agreement, including the
exhibits, documents and instruments referred to herein or therein,
constitutes the entire agreement, and supersedes all other prior agreements
