or warranty; and

Company), shall not be deemed to be an "Acquiring Person" (as defined in the

Agreement shall terminate for any reason). The Company agrees that if any other
Person shall be deemed not to be such an "Acquiring Person" (or such other
Person is otherwise granted any exemption or release from or any beneficial
rights with respect to the Rights Agreement), then Vista shall be granted the
same exemption, release or rights as such other Person with respect to the
Rights Agreement (provided that this sentence shall be of no force and effect in

Subsidiary to:

          (a) use its reasonable best efforts to maintain at all times a valid
listing for the Common Stock on a national securities exchange or NASDAQ;

material respect, in each case than the directors' and officers' liability
insurance maintained by the Company as of the Closing Date;

governmental charges or levies imposed upon its properties or upon the income or

domestic securities exchange upon which shares of Common Stock may be listed
(except for official notice of issuance which shall be immediately transmitted
by the Company upon issuance);

          (i) use its reasonable best efforts to at all times file all reports
(including annual reports, quarterly reports and the information, documentation
and other reports) required to be filed by the Company under the Exchange Act
and Sections 13 and 15 of the rules and regulations adopted by the SEC
thereunder, and the Company shall use its reasonable best efforts to file each

similar rule or

regulation hereafter adopted by the SEC and to enable the Company to register
securities with the SEC on Form S-3 or any similar short-form registration
statement and upon the filing of each such report deliver a copy thereof to each
holder of the Series B Shares (or, if the Company is no longer subject to the
requirements of the Exchange Act, provide reports in substantially the same form
and at the same times as would be required if it were subject to the Exchange
Act).

     9.2  Use of Proceeds. The proceeds from the issuance of the Series B
Preferred Stock will be used by the Company (i) to repay outstanding
indebtedness and (ii) for working capital and general corporate purposes.

                                   ARTICLE XII
                                 INDEMNIFICATION

     12.1 Indemnification.

          (a) In consideration of Vista's execution and delivery of this
Agreement and acquiring the Series B Shares hereunder and in addition to all of
the Company's other obligations under this Agreement, the Company shall defend,
protect, indemnify and hold harmless Vista and all of its respective Affiliates,
officers, managers, advisors, directors, employees and agents (including,
without limitation, those retained in connection with the transactions
contemplated by this Agreement) (collectively, the "Indemnitees") from and
against any and all actions, causes of action, suits, claims (including without
limitation actions, causes of action, suits and claims brought by or against
Person, including stockholders of the Company on behalf of themselves and their
respective subsidiaries), losses, costs, penalties, fees, liabilities and
damages, and expenses (including, without limitation, costs of suit and all
reasonable attorneys' fees and expenses incurred in connection with
investigating, preparing for and responding to third party subpoenas or
enforcing this Agreement) in connection therewith (irrespective of whether any
such Indemnitee is a party to the action for which indemnification hereunder is
sought) or other liabilities, losses or, in the case of clauses (i) and (ii)
below, diminution in value (the "Indemnified Liabilities"), incurred by the
Indemnitees or any of them as a result of, or arising out of, or relating to (i)
the breach of any representation or warranty contained in this Agreement or in
any Related Document, (ii) the breach of any promise, agreement or covenant
contained in this Agreement or in any Related Document, (iii) the Company's
actions or failures to act (including statements or omissions made or
information provided by the Company or its agents), or (iv) actions or failures
to act by an Indemnitee with the Company's written consent or in reliance on the
Company's actions or failures to act.

          (b) The Company shall reimburse the Indemnitees for the Indemnified
Liabilities as such Indemnified Liabilities are incurred. To the extent that the
foregoing 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.
The indemnification provided for under this Agreement will remain in full force
and effect regardless of any investigation made by or on behalf of the
Indemnitee or any officer, director or controlling Person of such Indemnitee and
will survive the transfer of securities.

          (c) Any Person entitled to indemnification hereunder (i) will give
prompt written notice to the Company of any claim with respect to which it seeks
indemnification and (ii) if the Indemnified Liability arises from a third party
claim, unless in such Indemnitee's reasonable judgment a conflict of interest
between the Company and such Indemnitee may exist with respect to such third
party claim, will permit the Company to assume the defense of such claim with
counsel reasonably satisfactory to the Indemnitee. If such defense is assumed,
the Company will not be subject to any liability for any settlement made by the
Indemnitee without its consent (but such consent will not be unreasonably
withheld). If the Company is not entitled to, or elects not to, assume the
defense of a claim hereunder, the Company will not be obligated to pay the fees
and expenses of more than one counsel for all Indemnitees with respect to such
claim, unless in the reasonable judgment of any Indemnitee a conflict of
interest may exist between such Indemnitee and any other of such Indemnitees
with respect to such claim. In such instance, the conflicting Indemnitees shall
have the right to obtain one separate counsel, chosen by the majority of each
separate group of conflicting Indemnitees, at the expense of the Company.

          (d) Payments by the Company pursuant to Section 12.1(a) shall be
limited to the amount of any liability or damage that remains after deducting
therefrom any insurance proceeds and any indemnity, contribution or other
similar payment recovered by the Indemnitees from any third party with respect
thereto.

                                      -30-



          (e) Notwithstanding anything to the contrary set forth herein, no
Indemnitee shall be entitled to be indemnified pursuant to this Article XII for
any Indemnified Liability that arises as a result of the Indemnitee's gross
negligence or willful misconduct; provided, however, that the Company shall pay
the expenses incurred by any such Indemnitee hereunder, as such expenses are
incurred, in connection with any proceeding in advance of the final disposition,
so long as the Company receives an undertaking by such Indemnitee to repay the
full amount advanced if there is a final determination that such Indemnitee
failed the standards set forth above or that such Indemnitee is not entitled to
indemnification as provided herein for other reasons; and provided, further,
that the termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or a plea of nolo contendere or its equivalent, shall
not, of itself, create a presumption that such Indemnitee was either grossly
negligent or engaged in willful misconduct.

                                  ARTICLE XIII
                               GENERAL PROVISIONS

     13.5 Closing Fee; Vista's Fees and Expenses.

          (a) On the Closing Date, in consideration for the services Vista or
its Affiliates performed in structuring and arranging the transactions
contemplated by this Agreement and the Related Documents, the Company will pay
to Vista Equity Partners, LLC (or its Affiliate) a transaction fee equal to
$500,000 (the "Closing Fee"), by wire transfer of immediately available funds to
an account indicated to the Company by Vista. In addition, on the earlier of (x)
the Closing Date, and (y) the third business day after this Agreement is
terminated, unless (A) the Termination Fee under Section 7.8(b) and the Closing
Fee is paid to Vista, or (B) this Agreement is terminated pursuant to Section
10.1(b), 10.1(c), or 10.1(e)(i), the Company shall reimburse Vista for (i) the
reasonable fees and expenses of Kirkland & Ellis and PriceWaterhouseCoopers LLP
incurred by Vista in connection with the documentation, negotiation and
consummation of the transactions contemplated by this Agreement and the Related
Documents, and (ii) all other reasonable fees and out-of-pocket expenses
incurred by Vista in connection with the

                                      -32-



transactions contemplated hereunder (including, without limitation, fees and
expenses of legal counsel, accountants, investment bankers, brokers or other
representatives). After the Closing, the Company agrees to reimburse Vista for
all reasonable fees and expenses (including reasonable legal fees) incurred in
connection with any future amendment to, waiver of or the enforcement by Vista
of any of its rights arising under this Agreement or any of the Related
Documents.

          (b) In addition to any amounts payable pursuant to the second sentence
of clause (a) above, if this Agreement is terminated by Vista or the Company
pursuant to Sections 10.1(a), 10.1(d), 10.1(e)(ii), 10.1(f), 10.1(g) or 10.1(h),
then, in addition to any other remedies or claims Vista may have in law or in
equity, the Company shall, within three business days of such notice of
termination, pay to Vista Equity Partners, LLC the Closing Fee. Any amounts
payable under this Section 13.5(b) shall be paid by wire transfer of immediately
available funds to the accounts designated to the Company by Vista.

     13.6 Amendment and Waiver. No amendment or waiver of any provision of this
Agreement shall be effective, unless the same shall be in writing and signed by
the Company and Vista. No such waiver shall operate as a waiver of, or estoppel
with respect to, any subsequent or other failure. No failure by any party to
take any action against any breach of this Agreement or default by any other
party shall constitute a waiver of such party's right to enforce any provision
hereof or to take any such action.

     13.7 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one agreement.

     13.8 Headings. The headings of the various sections of this Agreement have
been inserted for reference only and shall not be deemed to be a part of this
Agreement.

     13.9 Specific Performance. The Company, on the one hand, and Vista, on the
other hand, acknowledges that money damages may not be a sufficient remedy for
any breach of this Agreement. It is accordingly agreed that the parties shall be
entitled to seek specific performance and injunctive relief as remedies for any
such breach, these remedies being in addition to any of the remedies to which
they may be entitled at law or equity.

     13.10 Remedies Cumulative. Except as otherwise provided herein, the
remedies provided herein shall be cumulative and shall not preclude the
assertion by any party hereto of any other rights or the seeking of any other
remedies against any other party hereto.

     13.11 GOVERNING LAW. THE CORPORATE LAW OF THE STATE OF CALIFORNIA SHALL
GOVERN ALL ISSUES AND QUESTIONS RELATING TO THE INTERNAL GOVERNANCE OF THE
COMPANY AND ANY OTHER ISSUES AND QUESTIONS ARISING UNDER THE SCOPE OF THE
CORPORATE LAW OF THE STATE OF CALIFORNIA. ALL ISSUES AND QUESTIONS RELATING TO
THE CONSTRUCTION, INTERPRETATION AND ENFORCEMENT OF THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
DELAWARE, WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS OR CHOICE OF
LAW OF THE STATE OF DELAWARE OR ANY OTHER JURISDICTION WHICH WOULD RESULT IN THE
APPLICATION OF THE LAW OF ANY JURISDICTION OTHER THAN THE STATE OF DELAWARE

     13.12 Arbitration.

          (a) Resolution of Disputes. If a Dispute arises between the parties,
the parties agree to use the following procedures in good faith to resolve such
Dispute promptly and non-judicially. For

                                      -33-



purposes of this Agreement, "Dispute" shall mean any alleged material breach of
any representation, warranty or obligation herein, or a disagreement regarding
the interpretation, performance or nonperformance of any provision thereof, or
the validity, scope and enforceability of these dispute resolution procedures,
or any dispute regarding any damages arising from the termination of this
Agreement. Any party may give written notice to any other party of the existence
of a Dispute (a "Dispute Notice").

          (b) Negotiation. Within ten days after delivery of any Dispute Notice
the parties involved in the Dispute shall meet at a mutually agreeable time and
place and thereafter as often as they deem reasonably necessary to exchange
relevant information and attempt in good faith to negotiate a resolution of the
Dispute. If the Dispute has not been resolved within ten days after the first
meeting of the parties, or, if the party receiving the Dispute Notice will not
meet within ten days after receipt of the Dispute Notice, then either party may,
by delivering notice to the other party, commence arbitration proceedings.

          (c) Arbitration. If the parties are not successful in resolving a
Dispute, then the Dispute shall be resolved by binding arbitration conducted by
three arbitrators in accordance with the Commercial Arbitration Rules of the
American Arbitration Association as in effect from time to time as modified by
the terms hereof (the "Arbitration Law"). Either party may initiate final
resolution of the Dispute by delivering a written demand for arbitration to the
other party. Each party shall notify the other party of its appointment of one
neutral arbitrator within seven days after receipt of such written demand for
arbitration and the third neutral arbitrator shall be appointed by a court of
competent jurisdiction in New York. Each of the three arbitrators shall function
as an arbitrator without any one of them serving as an Umpire or having more
authority than the other two. If such arbitrator appointments are not made
within said time periods, the arbitrators shall be selected by a court of
competent jurisdiction in New York. All arbitrators must be attorneys with
experience in law relating to investment funds. Further, no arbitrator may be a
current or former client or employee of any party or an attorney that has
provided legal advice to any party within the preceding twelve months, nor may
an arbitrator be a current or former employee of a direct competitor of any of
the parties. Additionally, prior to their assumption of duties as an arbitrator,
all arbitrators must sign an oath of neutrality in customary form. If requested
by either party, the arbitration award shall set forth findings of fact and
conclusions of law upon which the award is based in the same manner as a
judgment from a court of New York. Judgment upon the award rendered by the
arbitrators shall be binding upon the parties and may be entered by any court
having jurisdiction thereof. The place of arbitration shall be New York, unless
the parties mutually agree otherwise. The language of the arbitration shall be
English. The arbitrators may allocate against the losing party all reasonable
attorneys' fees and costs of arbitration including the fees of the arbitrators
and any other costs described herein so long as such arbitrators direct in the
award that any such costs shall not be taxable in the courts of New York. The
parties agree that a party's remedies under this arbitration procedure may be
inadequate and that, notwithstanding this clause (c), such aggrieved party shall
be entitled to seek injunctive relief. The institution and maintenance of an
action to obtain or enforce equitable remedies shall not constitute a waiver of
the right of any party including the plaintiff to submit the controversy or
claim to arbitration.

          (d) General Dispute Resolution Provisions.

              (i) All deadlines specified in this Section 13.12 may be extended
     by mutual agreement. The procedures specified in this Section 13.12 are an
     essential provision of the Agreement and are legally binding on the
     parties. These procedures shall be the sole and exclusive procedures for
     the resolution of any Dispute between the parties arising out of or
     relating to this Agreement. Any and all actions to enforce the obligations
     under this Section 13.12 shall be brought in any court of competent
     jurisdiction in courts located in New York.

                                      -34-



              (ii) The parties acknowledge that the provisions of this Section
     13.12 are intended to provide a private resolution of Disputes between
     them. Accordingly, all documents, records, and other information relating
     to the Dispute shall at all times be maintained in the strictest confidence
     and not disclosed to any third party, other than the arbitrators, except
     where specifically allowed hereunder and except as required to be disclosed
     as a matter of law. All proceedings, communications and negotiations
     pursuant to this Section 13.12 are confidential. In the event of any
     judicial challenge to, or enforcement of, any order or award hereunder, any
     party may designate such portions of the record of such proceedings,
     communications, and negotiations as such party deems appropriate to be
     filed under seal. All proceedings, communications and negotiations pursuant
     to this Section 13.12 shall be treated as compromise negotiations for all
     purposes, including for purposes of the U.S. Federal Rules of Evidence and
     state rules of evidence. None of the statements, disclosures, offers, or
     communications (or other assertions made in any proceeding or negotiation)
     made pursuant to this Section 13.12 shall be deemed admissions, nor shall
     any of said statements, disclosures, offers, communications or assertions
     be admissible for any purpose other than the enforcement of the terms of
     this Section 13.12.

              (iii) The parties agree to act in good faith to comply with all of
     their respective obligations under this Agreement as much as possible as if
     there were no Dispute during any pending mediation or arbitration
     hereunder.

              (iv) The parties agree that the terms of this Section 13.12 shall
     survive the termination or expiration of this Agreement.

          (e) Notice. The parties agree to have any Dispute decided by neutral
arbitration as provided in this Section 13.12 and the parties are giving up any
rights they might possess to have the Dispute litigated in a court or by a jury
trial. The parties are giving up their judicial rights to discovery and appeal,
unless such rights are specifically included in this Section 13.12. The parties
acknowledge and agree that their agreement to this arbitration provision is
voluntary.

     13.13 No Third Party Beneficiaries. Except as specifically set forth or
referred to herein, nothing herein is intended or shall be construed to confer
upon any person or entity other than the parties hereto and their successors or
assigns, any rights or remedies under or by reason of this Agreement.

     13.14 Severability. If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

     13.15 Time of the Essence; Computation of Time. Time is of the essence for
each and every provision of this Agreement. Whenever the last day for the
exercise of any privilege or the discharge or any duty hereunder shall fall upon
a non-Business Day, the party having such privilege or duty may exercise such
privilege or discharge such duty on the next succeeding Business Day.

                                    * * * * *
