of the Merger and without any action on the part of the stockholders of the
Company, each Common Share issued and outstanding immediately prior to the

converted into the right to receive in cash the Merger Price payable to the

      Section 1.09 Company Options. Purchaser and the Company shall take all
actions necessary, including, without limitation, amendments to or termination

purchase Common Shares (collectively, the "Options"), under any Company stock
incentive plan or arrangement, whether or not then exercisable, shall become
fully exercisable, (B) each Option which is then outstanding shall be cancelled,
and (C) in consideration of such cancellation, and except to the extent that
Purchaser and the holder of any such Option otherwise agree, immediately

payment to be net of taxes required by law to be withheld with respect thereto).

consideration otherwise payable to any holder of Options pursuant to this
Agreement such amounts as may be required to be deducted and withheld with
respect to the making of such payment under the Internal Revenue Code of 1986,
as amended, and the rules and regulations promulgated thereunder (the "Code"),

the exercise price of any Option is greater than or equal to the Merger Price,
such Option shall be terminated and cancelled without any consideration being
payable to the holder thereof.

its stockholders (the "Special Meeting") to be duly called and held to consider
and vote upon the approval and adoption of this Agreement and the Merger, and
the Company will use its commercially reasonable efforts to hold the Special
Meeting as soon as practicable after the date of this Agreement. The Company
Board will, subject to Section 1.10(b) and Section 5.06, recommend such approval

approval, including, without limitation, timely mailing the Proxy Statement (as
defined in Section 1.11).

      (b) The Company Board will not withdraw, modify or change in a manner
adverse to Purchaser, its recommendation to the Company's stockholders unless
the Company Board determines in good faith, after consultation with counsel,
that such withdrawal or modification is required by law in order for the Company
Board to comply with its fiduciary duties to the Company's stockholders. Any
withdrawal, change or modification of the recommendation of the Company Board in
accordance with the previous sentence will not constitute a breach of the
Company's representations, warranties, covenants or agreements contained in this
Agreement. Unless this Agreement is previously terminated in accordance with
Article VII , the Company will submit this Agreement to its stockholders at the
Special Meeting in accordance with Section 1.10(a) even if the Company Board has
withdrawn, modified or changed its recommendation of this Agreement or the
transactions contemplated by this Agreement and will not postpone or adjourn
such meeting or the vote by the Company's stockholders upon this Agreement to
another date without Purchaser's approval or as otherwise required by law.

      Section 1.11 Proxy Statement and Schedule 13E-3.

      (a) As promptly as practicable after the execution of this Agreement, the
Company and Purchaser will cooperate to prepare and file a Schedule 13E-3
Transaction Statement (together with any amendments thereto, "Schedule 13E-3"),
and the Company will prepare and file with the SEC a proxy statement (together
with any amendments thereto, the "Proxy Statement") relating to the Special
Meeting. Both Purchaser and the Company will cause Schedule 13E-3 to comply as

Act and the rules and regulations thereunder, the rules and regulations of any
stock exchange or other listing organization that may be applicable and the
DGCL. The Company will cause the Proxy Statement to comply as to form in all
material respects with the applicable provisions of the Exchange Act and the
rules and regulations thereunder, the rules and regulations of any stock
exchange or other listing organization that may be applicable and the DGCL. Both
the Company and Purchaser will furnish to each other all information concerning
the Company or Purchaser each may reasonably request in connection with such
actions and the preparation of Schedule 13E-3 and the Proxy Statement. Purchaser
will be given a reasonable opportunity to review and comment on all filings by
the Company with the SEC in connection with the transactions contemplated
hereby, including the Proxy Statement and any amendment or supplement thereto,
and all mailings to the Company's stockholders in connection with the
transaction contemplated by this Agreement. The Company will be given a
reasonable opportunity to review and comment on all filings by Purchaser with
the SEC in connection with the transactions


                                      -4-

contemplated hereby, including Schedule 13E-3 and any amendment or supplement
thereto. The Company, with the cooperation of Purchaser, will use its
commercially reasonable efforts to cause the Proxy Statement to be mailed to
each of the Company's stockholders as promptly as practicable after the
compliance with SEC filing requirements and, if necessary, satisfactory
resolution of SEC comments. The Company will also promptly as practicable file,
and, if required, mail to the Company's stockholders, any amendment to the Proxy
Statement which may become necessary after the date the Proxy Statement is first
mailed to the Company's stockholders. The Company and Purchaser will also
promptly as practicable file any amendment to Schedule 13E-3 which may become
necessary after the date Schedule 13E-3 is first filed with the SEC.

      (b) No amendment or supplement to the Proxy Statement or Schedule 13E-3
will be made by the Company without the prior written approval of Purchaser,
which approval will not be unreasonably withheld, conditioned or delayed. The
Company will advise Purchaser promptly after it receives notice thereof of any
request by the SEC or any stock exchange or other listing organization that may
be applicable for amendment of the Proxy Statement or Schedule 13E-3 or comments
thereof and responses thereto or requests by the SEC for additional information.

      (c) The Proxy Statement will include the recommendation of the Company
Board to the stockholders of the Company that they vote in favor of the adoption
of this Agreement and the Merger, except as otherwise provided in Section 1.10
or 5.06 of this Agreement.

      (d) The information supplied by the Company included in the Proxy
Statement and Schedule 13E-3 will not, at (i) the time the Proxy Statement and
Schedule 13E-3 is filed with the SEC; (ii) the time the Proxy Statement (or any
amendment thereof or supplement thereto) is first mailed to the stockholders of

necessary in order to make the statements therein not misleading, except that no
representation or warranty is made by the Company with respect to statements
made in or incorporated by reference therein based on information supplied by or
on behalf of Purchaser specifically for inclusion or incorporation by reference
therein. If at any time prior to the Effective Time any event or circumstances
relating to the Company or any of the Company subsidiaries, or their respective
officers and, should be discovered by the Company that should be set forth in an
amendment or a supplement to the Proxy Statement or Schedule 13E-3, the Company

                                   ARTICLE II

                  DISSENTING SHARES; PAYMENT FOR COMMON SHARES

      Section 2.01 Dissenting Shares. Notwithstanding anything in this Agreement
to the contrary, Common Shares outstanding immediately prior to the Effective
Time and held by a holder of Common Shares who has not voted in favor of the
Merger or consented thereto in writing and who demands in writing an appraisal
for such Common Shares in accordance with Section 262 of the DGCL, if such
Section 262 provides for appraisal rights for such Common Shares in the Merger
("Dissenting Shares"), shall not be converted into the right to receive the
Merger Price as provided in Section 1.07 but shall be entitled to receive the
consideration as shall be determined pursuant to Section 262 of DGCL, unless and
until such holder fails to perfect or withdraws or otherwise loses his right to
appraisal and payment under the DGCL. If, after the Effective Time, any such
holder fails to perfect or withdraws or loses his right to appraisal, such
Dissenting Shares shall thereupon be treated as if they had been converted as of
the Effective Time into the right to receive the Merger Price, if any, to which
such holder is entitled, without interest or dividends thereon. The Company
shall give Purchaser prompt notice of any demands received by the Company for
appraisal of Common Shares, withdrawals of such demands and any other
instruments served pursuant to the DGCL and received by the Company and, prior
to the Effective Time, Purchaser and the Company shall cooperate with each other
in all negotiations and proceedings with respect to such demands. Prior to the
Effective Time, the Company shall not, except with the prior written consent of
Purchaser, make any payment with respect to, or settle or offer to settle, any
such demands.

      Section 2.02 Payment for Common Shares.

      (a) From and after the Effective Time, a bank or trust company designated
by Purchaser and reasonably acceptable to the Company shall act as paying agent
(the "Paying Agent") in effecting the payment of the Merger Price in respect of
certificates (the "Share Certificates") that, prior to the Effective Time,
represented Common Shares entitled to payment of the Merger Price pursuant to
Section 1.07. At the Effective Time, the Company shall deposit, or cause to be
deposited, in trust with the Paying Agent the aggregate Merger Price to which
holders of Common Shares shall be entitled at the Effective Time pursuant to
Section 1.07.

      (b) Promptly after the Effective Time, the Paying Agent shall mail to each
record holder of Share Certificates that, immediately prior to the Effective
Time, represented Common Shares (other than Share Certificates representing
Dissenting Shares and Share Certificates representing Common Shares held by
Purchaser or any wholly-owned subsidiary of Purchaser, in the treasury of the
Company or by any wholly-owned subsidiary of the Company that are to be
cancelled in accordance with Section 1.07) (i) a form of letter of transmittal
which shall specify that delivery shall be effected, and risk of loss and title
to the Share Certificates shall pass, only upon proper delivery of the Share
Certificates to the Paying Agent and which shall be in such form and have such
other provisions as Purchaser and the Company may reasonably specify and (ii)
instructions for use in surrendering such Share Certificates and receiving the
aggregate Merger Price in respect thereof. Upon surrender of each such Share
Certificate together with such letter of transmittal duly completed and validly
executed in accordance with the instructions thereto, the Paying Agent shall pay
the holder of such Share Certificate the Merger Price multiplied by the


                                      -6-

number of Common Shares formerly represented by such Share Certificate in
consideration therefor, and such Share Certificate shall forthwith be cancelled.
Until so surrendered, each such Share Certificate (other than Share Certificates
representing Dissenting Shares and Share Certificates representing Common Shares
held by Purchaser, any wholly-owned subsidiary of Purchaser, in the treasury of
the Company or by any wholly-owned subsidiary of the Company that are to be
cancelled in accordance with the Section 1.07) shall represent solely the right
to receive the aggregate Merger Price relating thereto. No interest or dividends
shall be paid or accrued on the Merger Price. If the Merger Price (or any
portion thereof) is to be delivered to any person other than the person in whose
name the Share Certificate formerly representing Common Shares surrendered
therefor is registered, it shall be a condition to such right to receive such
Merger Price, that the Share Certificate so surrendered shall be properly
endorsed, with signature guaranteed, or otherwise be in proper form for transfer
and that the person surrendering such Share Certificates shall pay to the Paying
Agent any transfer or other taxes required by reason of the payment of the
Merger Price, to a person other than the registered holder of the Share
Certificate surrendered, or shall establish to the satisfaction of the Paying
Agent that such tax has been paid or is not applicable.

      (c) Promptly following the date that is six months after the Effective
Time, the Paying Agent shall deliver to the Surviving Corporation all cash,
Share Certificates and other documents in its possession relating to the
transactions described in this Agreement, and the Paying Agent's duties shall
terminate. Thereafter, each holder of a Share Certificate formerly representing
a Common Share shall thereafter look only to the Surviving Corporation (as a
general creditor thereof) for payment of its claim for the Merger Price (without
any interest or dividends thereon).

      (d) No Liability. To the extent permitted by applicable law, none of
Purchaser, the Company, the Surviving Corporation or the Paying Agent shall be
liable to any person in respect of any cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

      (e) Investment of Merger Price. The Paying Agent shall invest the Merger
Price as directed by the Surviving Corporation; provided that such investments
shall be in obligations of or guaranteed by the United States of America, in
commercial paper obligations rated A-1 or P-1 or better by Moody's Investors
Service, Inc. or Standard & Poor's Corporation, respectively, or in certificates
of deposit, bank repurchase agreements or banker's acceptances of commercial
banks with capital exceeding $1 billion. Any interest resulting from such
investment shall be paid to the Surviving Corporation.

      (f) Transfer of Common Shares. After the Effective Time, there shall be no
registrations of transfers on the stock transfer books of the Surviving
Corporation of any Common Shares which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates formerly representing
Common Shares are presented to the Surviving Corporation or the Paying Agent,
they shall be surrendered and cancelled in consideration for the payment of the
aggregate Merger Price relating thereto, as provided in this Article II.

      (g) No Further Ownership Rights in Common Shares Exchanged For Cash. All
cash paid upon the surrender for exchange of Certificates representing Common
Shares in accordance with the terms of this Article II shall be deemed to have
been issued (and paid) in full satisfaction


                                      -7-

of all rights pertaining to the Common Shares exchanged for cash theretofore
represented by such Certificates in accordance with the DGCL.

      (h) Lost Certificates. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such person of a bond in such amount as
the Surviving Corporation may direct as indemnity against any claim that may be
made against it with respect to the Certificate, the Paying Agent shall deliver
in exchange for such lost, stolen or destroyed Certificate the applicable Merger
Price with respect thereto.

      (i) Withholding of Tax. The Company or the Surviving Corporation or any of
their respective affiliates shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any former holder
of Common Shares such amounts as the Company or the Surviving Corporation (or
any of their respective affiliate thereof) is required to deduct and withhold
with respect to the making of such payment under the Code, or any provision of
state, local or foreign tax law. To the extent that amounts are so withheld by
the Company or the Surviving Corporation and paid by the Company or the
Surviving Corporation to the applicable taxing authority, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
former holder of Common Shares in respect of which such deduction and
withholding was made by the Company or the Surviving Corporation.

                                  ARTICLE III

operated or leased by it makes such qualification, licensing or good standing

be expected to have a Material Adverse Effect on the Company. As used in this
Agreement, the term "Material Adverse Effect on the Company" means any change or
effect that would be materially adverse to the assets, liabilities, business,
prospects, operations or condition (financial or otherwise) of the Company


                                      -8-

any kind whatsoever, whether or not accrued and whether or not contingent or
absolute, that are material to the Company and its subsidiaries, taken as a
whole, other than (i) liabilities disclosed or

reasonably be expected to have a Material Adverse Effect on the Company.

      (e) The Company has heretofore furnished or made available to Purchaser a
complete and correct copy of any amendments or modifications which have not yet
been filed with the SEC to agreements, documents or other instruments which

however, to existing confidentiality and similar non-disclosure obligations and
the preservation of attorney-client and work product privileges), during normal
business hours and upon reasonable notice, to its officers and employees and to
its offices and other facilities and to the books and records of the Company and
its subsidiaries, and will permit Purchaser to make inspections of such as

the Company's subsidiaries to furnish Purchaser and the Purchaser
Representatives to the extent available with such other financial and operating

request. Unless otherwise required by law, Purchaser will, and will cause the
Purchaser Representatives to, hold any such information in confidence until such
time as such information otherwise becomes publicly available through no
wrongful act of Purchaser or the Purchaser Representatives. No investigation
pursuant to this Section 5.01 shall affect any representations or warranties of
the parties herein or the conditions to the obligations of the parties hereto.
In the event of termination of this Agreement for any reason, Purchaser will,
and will cause the Purchaser Representatives to, return to the Company or
destroy all copies of written information furnished by the Company or any of the

                                      -15-

      (d) Each of the parties agrees to cooperate with each other in taking, or
causing to be taken, all actions necessary to delist the Common Shares from the
NASDAQ National Market System ("NASDAQ") or the OTC Bulletin Board ("OTC") if

      Section 5.03 Consents.

      Section 5.05 Continuance of Existing Indemnification Rights.


      (a) The Company will, and after the Effective Time, Purchaser agrees that
it will cause the Surviving Corporation to, until the expiration of any
applicable statutes of limitation, (i) indemnify and hold harmless each present
and former director, officer and employee of the Company (collectively, the
"Company Indemnified Parties") against any costs or expenses (including
reasonable attorneys' fees), judgments, fines, losses, claims, damages or
liabilities (collectively, "Costs") (but only to the extent such Costs are not
otherwise covered by insurance and paid) incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative (collectively, "Claims"), arising out of or
pertaining to matters existing or occurring at or prior to the Effective Time,
including, in any event, in connection with the Merger and this Agreement,
whether asserted or claimed prior to, at or after the Effective Time, to the
fullest extent permitted under applicable law, and (ii) keep in effect the
provisions in its certificate of incorporation and bylaws containing the
provisions with respect to exculpation of director and officer liability,
advancement of expenses, and indemnification set forth in the certificate of
incorporation and bylaws of the Company on the date of this Agreement to the
fullest extent permitted under applicable law, which provisions shall not be
amended, repealed or otherwise modified in any manner adverse to the Company
Indemnified Parties, without the prior written consent of such persons, except
as required by applicable law; provided, further, that the Surviving Corporation
shall not be required to indemnify or hold harmless any Company Indemnified
Parties in respect of acts or omissions occurring at or prior to the Effective
Time to the Extent such acts or omissions relate to the Indemnified Parties'
gross negligence, willful misconduct or bad faith.

      (b) Any Company Indemnified Party wishing to claim indemnification under
this Section 5.05 after the Effective Time, upon learning of any such claim,
action, suit, proceeding or investigation, shall promptly notify the Surviving
Corporation thereof, but the failure to so notify shall not relieve the
Surviving Corporation of any liability it may have to such Company Indemnified
Party if such failure does not significantly prejudice the Surviving
Corporation. In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) the
Surviving Corporation shall have the right to assume the defense thereof and the
Surviving Corporation shall not be liable to such Company Indemnified Parties
for any legal expenses of other counsel or any other expenses subsequently
incurred by such Company Indemnified Parties in connection with the defense
thereof, except that if the Surviving Corporation elects not to assume such
defense, or counsel for the Company Indemnified Parties advises the Surviving
Corporation in writing that there are issues which raise conflicts of interest
between the Surviving Corporation and the Company Indemnified Parties, the
Company Indemnified Parties may retain counsel reasonably satisfactory to them,
and the Surviving Corporation shall pay all reasonable fees and expenses of such
counsel for the Company Indemnified Parties promptly as statements therefor are
received; provided, however, that (i) the Surviving Corporation shall be
obligated pursuant to this paragraph (b) to pay for only one counsel (as well as
any local counsel) for all Company Indemnified Parties, (ii) the Company
Indemnified Parties will cooperate in the defense of any such matter and (iii)
the Surviving Corporation shall not be liable for any settlement effected
without its prior written consent, which will not be unreasonably withheld; and
provided, further, that the Surviving Corporation shall not have any obligation
hereunder to any Company Indemnified Party if and when a court


                                      -17-

of competent jurisdiction shall ultimately determine that the indemnification of
such Company Indemnified Party in the manner contemplated hereby is prohibited
by applicable law.

      (c) This Section 5.05 is intended to be for the benefit of, and shall be
enforceable by, each of the Company Indemnified Parties and their respective
heirs and successors. The indemnification provided for herein shall not be
deemed exclusive of any other rights to which a Company Indemnified Party is
entitled, whether pursuant to law, contract or otherwise. The Company shall pay
all expenses, including reasonable attorneys' fees, that are incurred by any
Company Indemnified Party which is the prevailing party in any action or
proceeding to enforce the indemnity and other obligations provided for in this
Section 5.05.

      (d) In the event that the Surviving Corporation or any of its controlling
persons or successors or assigns (i) consolidates with or merges into any other
person and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers or conveys all or substantially
all of its properties and assets to any person, then, and in each such case, to
the extent necessary to effectuate the purpose of this Section 5.05, proper
provision shall be made so that the successors and assigns of the Surviving
Corporation or such controlling persons shall succeed to the obligations set
forth in this Section 5.05 and none of the actions described in clauses (i) or
(ii) shall be taken until such provision is made.

      Section 5.06 No Solicitation. The Company agrees that it shall not (and
shall not authorize any of its subsidiaries or any of the officers and directors
of it or its subsidiaries or its and its subsidiaries' directors, officers,
employees, affiliates, agents, advisors and representatives to), directly or
indirectly, (a) solicit, initiate or encourage, or take any other action to
facilitate (including by way of furnishing information) any Takeover Proposal
(as defined herein) or take any other action which may be reasonably expected to
lead to any Takeover Proposal, other than the transactions contemplated by this
Agreement, or any other transaction the consummation of which would reasonably
be expected to impede, interfere with, prevent or delay the Merger or which
would reasonably be expected to adversely affect the benefits to Purchaser of
the transactions contemplated hereby, (b) negotiate, explore or otherwise
participate in discussions with any person (other than Purchaser or its
directors, stockholders, officers, employees, agents and representatives, as
applicable), including any parties with which the Company has previously engaged
in discussions or negotiations with respect to any Takeover Proposal or
potential Takeover Proposal, or furnish to any person (other than Purchaser or
its directors, stockholders, officers, employees, agents and representatives, as
applicable) any information with respect to its business, properties or assets
or any of the foregoing, or otherwise cooperate in any way with, or assist or
participate in, facilitate or encourage, any effort or attempt by any other
person (other than Purchaser or its directors, stockholders, officers,
employees, agents and representatives, as applicable) to do or seek any of the
foregoing or (c) enter into any agreement, arrangement or understanding with
respect to, or endorse, any Takeover Proposal; provided, however, that the
foregoing shall not prohibit the Company from (i) prior to the date on which the
Company's stockholders adopt this Agreement in accordance with the DGCL (A)
furnishing information pursuant to a confidentiality agreement (provided for
informational purposes to Purchaser), on terms and conditions customary for
similar transactions, concerning the Company and its businesses, properties or
assets to a third party who has made an unsolicited bona fide written Takeover
Proposal, or (B) engaging in discussions or negotiations with such a third party
who has made an unsolicited bona fide written Takeover Proposal which did not
otherwise result from


                                      -18-

a breach of this Section 5.06 or (ii) following receipt of an unsolicited bona
fide written Takeover Proposal, but prior to the date on which the Company's
stockholders adopt this Agreement in accordance with the DGCL, failing to make
or withdrawing or modifying its recommendation referred to in Section 1.10, but,
in each case referred to in the foregoing clauses (i) or (ii), only to the
extent that the Company Board shall have concluded in good faith, after
consultation with outside legal counsel and the Company's financial advisors,
that (A) such Takeover Proposal may reasonably be expected to result in, in the
case of clause (i), or is, in the case of clause (ii), a proposal that is more
favorable to the stockholders of the Company than the transactions contemplated
by the Merger and this Agreement (taking into account all legal, financial,
regulatory and other aspects of the proposal and the person making the
proposal), and does not contain any conditions to the consummation of such
Takeover Proposal which are more onerous than the conditions, set forth in this
Agreement, (B) such Takeover Proposal is not conditioned on obtaining financing
(and with respect to which Purchaser has received written evidence, in form and
substance reasonably acceptable to Purchaser, of such third party's ability to
fully finance its Takeover Proposal) and provides for consideration to
stockholders of the Company payable solely in cash, (C) such Takeover Proposal
is for all or substantially all of the Common Shares, and (D) the Company
Board's fiduciary duties, as they would exist in the absence of any limitation
in this Agreement, would require the Company Board to take such action (any
Takeover Proposal satisfying each of the immediately preceding clauses (A), (B),
(C) and (D), hereinafter referred to as a "Superior Proposal"); provided,
further, that the Company Board shall not take any of the foregoing actions
referred to in clauses (i) and (ii) until after prior written notice to
Purchaser with respect to such action. After taking any such action, the Company
Board shall promptly advise Purchaser with respect to the status thereof as
developments arise or as reasonably requested by Purchaser. Nothing herein shall
prevent the Company Board from taking, and disclosing to the Company's
stockholders, a position contemplated by Rules 14D-9 and 14e-2 promulgated under
the Exchange Act with regard to any tender offer. In addition, if the Company
Board receives an unsolicited Takeover Proposal or any inquiry with respect to
or which could lead to any Takeover Proposal, then the Company shall promptly
inform Purchaser orally and in writing of the terms and conditions of such
Takeover Proposal and the identity of the person making it and if any Takeover
Proposal is in writing, the Company shall promptly deliver a copy thereof to
Purchaser. The Company agrees that it will use reasonable best efforts to
promptly inform its directors, officers, key employees, agents and
representatives of the obligations undertaken in this Section 5.06. As used in
this Agreement, "Takeover Proposal" means any proposal or offer from any person
relating to direct or indirect acquisition or purchase of a business that
constitutes 10% or more of the net revenues, net income or the assets of the
Company and its subsidiaries, taken as a whole, or 10% or more of any class of
equity securities of the Company or any of its subsidiaries, any tender offer or
exchange offer that if consummated would result in any person beneficially
owning 10% or more of any class of equity securities of the Company or any of
its subsidiaries, or any merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving the
Company or any of its subsidiaries, other than the transactions contemplated by
this Agreement.

      Section 5.07 Notification of Certain Matters. Purchaser and the Company
shall promptly notify each other of (a) the occurrence or non-occurrence of any
fact or event which would be reasonably likely (i) to cause any representation
or warranty contained in this Agreement to be untrue or inaccurate at any time
from the date hereof to the Effective Time or


                                      -19-

(ii) to cause any covenant, condition or agreement hereunder not to be complied
with or satisfied, and (b) any failure of the Company or Purchaser, as the case
may be, to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder, including, but not limited to the
Company's obligation to inform the Purchaser of receipt of an unsolicited
Takeover Proposal or inquiry pursuant to Section 5.06 hereof; provided, however,
that no such notification shall affect the representations or warranties of any
party or the conditions to the obligations of any party hereunder, nor shall it
limit or otherwise affect the remedies available hereunder to the party
receiving such notice.

      Section 5.08 Disposition of Litigation.


      (a) The Company agrees that it will not settle any litigation currently
pending, or commenced after the date hereof, against the Company or any of its
directors or officers by any stockholder of the Company relating to the Merger
or this Agreement, without the prior written consent of Purchaser, other than
settlements for amounts not exceeding $300,000, in the aggregate.

      (b) The Company will not voluntarily cooperate with any third party which
has sought or may hereafter seek to restrain or prohibit or otherwise oppose the
Merger and will cooperate with Purchaser to resist any such effort to restrain
or prohibit or otherwise oppose the Merger, unless in each case, the Company
Board determines in good faith after consultation with outside legal counsel,
that its fiduciary duties require it to do so.

      Section 5.09 State Takeover Laws. The Company shall, upon the request of
Purchaser, take all reasonable steps to assist in any challenge by Purchaser to
the validity or applicability to the transactions contemplated by this Agreement
and the Merger of any state or foreign takeover law.

      Special Meeting shall have been held and the Statutory Vote or the
      Majority of Minority Stockholder Vote are not obtained upon a vote taken
      at such meeting (including any adjournment or postponement thereof).

            (c) by the Company, if (i) Purchaser shall have breached any
      representation, warranty, covenant or agreement contained in this
      Agreement, which breach materially adversely affects the Company's ability
      to consummate the Merger, and, with respect to


                                      -23-

      any such breach that is reasonably capable of being cured, which shall not
      have been cured prior to the tenth business day following notice of such
      breach, or (ii) prior to the consummation of the Merger, any person shall
      have made a bona fide Takeover Proposal that the Company Board determines,
      in good faith, is a Superior Proposal (after taking into account any
      revised proposal made by Purchaser during the Five-Day Period (as defined
      in this Section 7.01)); provided, however, that (1) such Superior Proposal
      did not result from a breach of Section 5.06 above or other covenant or
      agreement of the Company, (2) after consultation with outside legal
      counsel and the Company's financial advisors and acting in good faith, the
      Company Board shall have withdrawn its recommendation to the stockholders
      that the Merger is fair and advisable and in the best interests of the
      Company, and (3) prior to such termination by the Company, the Company
      Board shall, if requested by Purchaser in connection with a revised
      proposal made by Purchaser, negotiate in good faith with Purchaser in
      respect of such revised proposal for not less than five (5) business days
      (the "Five-Day Period"); and provided, further, that such termination
      under this clause (c)(ii) shall not be effective until the Company has
      reimbursed Purchaser for all of its fees and expenses as required by
      Section 7.03(b) hereof; or

            (d) by Purchaser, if (i) there shall have been a breach of any
      representation or warranty on the part of the Company contained in this
      Agreement which would reasonably be expected to have a Material Adverse
      Effect on the Company or which would materially adversely affect (or
      materially delay) the consummation of the Merger, unless as of the date of
      this Agreement, the Purchaser had Knowledge of such breach of
      representation or warranty; (ii) there shall have been a breach or failure
      to perform of any covenant or agreement on the part of the Company
      contained in this Agreement which would reasonably be expected to have a
      Material Adverse Effect on the Company or which would materially adversely
      affect (or materially delay) the consummation of the Merger, which, in the
      case of clause (i) or (ii), if such breach or failure to perform is
      reasonably capable of being cured, such breach or failure to perform shall
      not have been cured prior to the tenth business day following notice of
      such breach or failure to perform, provided, that, notwithstanding the
      foregoing, the Company shall not be deemed to have breached or failed to
      perform or comply with any of its covenants hereunder or breached or
      failed to comply with any of its obligations hereunder in the event that
      the Company's failure to comply with such covenant or obligation directly
      or indirectly resulted from any act or omission by any executive officer,
      director or stockholder of the Purchaser who is also an executive officer
      of the Company; (iii) the Company shall effect, or enter into any
      agreement with respect to, a transaction with any person pursuant to any
      Takeover Proposal (other than Purchaser) or the Company Board has resolved
      to do so, or (iv) the Company Board shall have withdrawn or modified in a
      manner adverse to Purchaser its approval or recommendation of the Merger
      or this Agreement or shall have recommended another offer or transaction,
      or shall have resolved to effect any of the foregoing; or the Financial
      Adviser shall have withdrawn or modified in a manner adverse to Purchaser
      its opinion that the Merger Price to be received by the holders of the
      Common Shares pursuant to the Merger (other than Purchaser or the
      stockholders of Purchaser) is fair to such holders from a financial point
      of view;



                                      -24-

            (e) by the Company or the Purchaser, if the Company enters into a
      written agreement with respect to a Superior Proposal in accordance with
      the terms of this Agreement, including, without limitation, payment of all
      fees and expenses of Purchaser pursuant to Section 7.03 hereof; or


                  (f) by either the Company or Purchaser, if the Merger shall
            not have become effective on or before November 15, 2003; provided,
            however, that the right to terminate this Agreement under this
            Section 7.01(f) shall not be available to any party whose failure to
            fulfill any obligation under this Agreement has been the cause of,
            or resulted in, the failure of the Effective Time to occur on or
            before such date.

      Section 7.02 Effect of Termination. In the event of the termination of
this Agreement pursuant to Section 7.01, this Agreement shall forthwith become
void and have no effect, without any liability on the part of any party or its
directors, officers or stockholders, other than the last two sentences of
Section 5.01, this Section 7.02 and Section 7.03, which shall survive any such
termination. Nothing contained in this Section 7.02 shall relieve any party from
liability for any breach of this Agreement.

      Section 7.03 Fees and Expenses.

      (a) In addition to any amounts payable to Purchaser pursuant to Section
7.03(b) below, all expenses incurred by the parties hereto, subject to the
limitation set forth below, shall be borne solely and entirely by the Company,
and the Company shall without exception, at the request of Purchaser, whether or
not the Merger has been withdrawn, terminated or consummated, promptly (but not
later than three business days after receipt of written invoices from Purchaser
evidencing such Expenses) reimburse Purchaser for all the Purchaser's Expenses
(as defined below) (subject to the limitation set forth below). As used in this
Section 7.03, the term "Expenses" means all out-of-pocket fees and expenses
actually incurred by Purchaser, whether before or after the execution and
delivery of this Agreement, in connection with the transactions contemplated by
this Agreement and the transactions contemplated hereby, including, without
limitation, reasonable fees and expenses payable to all banks, investors,
investment banking firms and other financial institutions, and their respective
agents and counsel, all fees and reasonable expenses of counsel, accountants,
experts and consultants to Purchaser and its investors, and, further, including
without limitation fees and reasonable expenses of, or incurred in connection
with, any litigation or other proceedings to collect the Fee (as hereinafter
defined), Expenses, or any of the fees, costs and expenses described in this
sentence. Purchaser shall not be reimbursed by the Company for any Expenses in
excess of $1,500,000.

      (b) In addition to any amounts payable to Purchaser pursuant to Section
7.03(a) above, if (i) this Agreement is terminated by the Company pursuant to
Section 7.01(c)(ii) or (e) or by Purchaser pursuant to Section 7.01(d) or (e),
or (ii) the transactions contemplated by this Agreement are not consummated
through no fault of Purchaser, and the Company, within one (1) year of the
termination of this Agreement, enters into an agreement for a Takeover Proposal
(the "Alternate Transaction"), then the Company shall pay to Purchaser a fee
(the "Fee") in an amount equal to $1,500,000 less all amounts paid to Purchaser
pursuant to Section 7.03(a) above in cash and in immediately available funds,
(A) in the case of clause (i) above, prior to any such


                                      -25-

termination of this Agreement or (B) in the case of clause (ii) above, upon the
execution of binding agreements relating to such Alternate Transaction or the
consummation of such Alternate Transaction, whichever is earlier.

      Section 7.04 Amendment. This Agreement may be amended by the Company and
Purchaser at any time before or after approval of the Merger by the stockholders
of the Company but, after any such approval, no amendment shall be made that
requires the further approval of the Company's stockholders without obtaining
such further approval. This Agreement may not be amended except by an instrument
in writing signed on behalf of each of the parties hereto.

      Section 7.05 Extension; Waiver. At any time prior to the Effective Time,
the parties hereto may (i) extend the time for the performance of any of the
obligations or other acts of any other party hereto, (ii) waive any inaccuracies
in the representations and warranties contained herein by any other party or in
any document, certificate or writing delivered pursuant hereto by any other
party or (iii) subject to applicable law, waive compliance with any of the
agreements of any other party or with any conditions to its own obligations. Any
agreement on the part of any party to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.

                                  ARTICLE VIII

                                 INDEMNIFICATION

      Section 8.01 Indemnification Obligation of the Company.


      (a) The Company agrees from and after the date hereof to indemnify
Purchaser and its respective affiliates, stockholders, officers, directors,
employees, agents, representatives and successors and assigns (each a "Purchaser
Indemnitee" and, collectively the "Purchaser Indemnitees") in respect of, and
save and hold each Purchaser Indemnitee harmless against and pay on behalf of or
reimburse each Purchaser Indemnitee as and when incurred, any and all losses,
claims, damages and expenses (including reasonable attorney's fees and expenses)
("Losses" or singularly, the "Loss") which any Purchaser Indemnitee suffers,
sustains or becomes subject to as a result of or by virtue of, without
duplication arising out of or relating to actions or omissions relating to the
Agreement, the Merger and the transaction contemplated hereby and thereby.

      Section 8.02 Indemnification Procedures.


      (a) Any person or entity making a claim for indemnification pursuant to
Section 8.01 above (each, an "Indemnified Party") must give the Company (an
"Indemnifying Party") written notice of such claim promptly after the
Indemnified Party receives any written notice of any action, lawsuit,
proceeding, investigation or other claim (a "Proceeding") against or involving
the Indemnified Party by any person or entity or otherwise discovers the
liability, obligation or facts giving rise to such claim for indemnification;
provided, that the failure to notify or delay in notifying an Indemnifying Party
will not relieve the Indemnifying Party of its obligations pursuant to Section
8.01 above, as applicable, except to the extent that such failure or delay
actually and materially harms the Indemnifying Party.



                                      -26-



      (b) With respect to the defense of any Proceeding against or involving an
Indemnified Party in which any person or entity in question seeks only the
recovery of a sum of money (and not for injunctive or equitable relief) for
which indemnification is provided in Section 8.01 above, at its option an
Indemnifying Party may appoint as lead counsel of such defense any legal counsel
approved by the Indemnified Party, such approval not to be unreasonably withheld
or delayed.

      (c) Notwithstanding Section 8.01 above: (i) the Indemnified Party will be
entitled to participate in the defense of such claim and to employ one counsel
of its choice for such purpose at the Company's expense and (ii) the
Indemnifying Party will not be entitled to assume control of the defense of such
claim, and will pay the reasonable fees and expenses of legal counsel retained
by the Indemnified Party, if:

            (x) an adverse determination of such Proceeding would be reasonably
      likely to have a material and adverse effect upon the Indemnified Party's
      business;

            (y) the Indemnified Party reasonably believes that there exists a
      conflict of interest which, under applicable principles of legal ethics,
      could prohibit a single legal counsel from representing both the
      Indemnified Party and the Indemnifying Party in such Proceeding; or

            (z) the Indemnified Party reasonably believes that the Indemnifying
      Party has failed or is failing to prosecute or defend vigorously such
      claim following written notice and a 30 day opportunity to cure.

      (d) the Indemnifying Party must obtain the prior written consent of the
Indemnified Party (which the Indemnified Party will not unreasonably withhold,
delay or condition) prior to entering into any settlement of such claim or
Proceeding or ceasing to defend such claim or Proceeding; provided that any such
settlement shall provide for the full release of all claims against each
Indemnified Party.

      SECTION 8.03 Payment. Upon the determination of the liability under
Article VIII or otherwise between the parties or by judicial proceeding, the
Company shall pay to the Indemnified Party, as the case may be, within ten (10)
days after such determination, the amount of any claim for indemnification made
hereunder. All amounts not paid when due under Article VIII will accrue
interest, payable on demand, at the rate of eighteen percent (18%) per annum, or
the highest rate permitted by applicable law, whichever is smaller, from the
date due until paid in full and each paying party will pay the other party's
reasonable and documented out-of-pocket costs and expenses (including without
limitation, reasonable attorneys' fees and expenses) incurred in attempting to
collect any such amounts.

      SECTION 8.04 Adjustment to Indemnities. The amount of indemnity payable
under Section 8.01 shall be (i) calculated after giving effect to any proceeds
actually received from insurance policies covering the Loss that is the subject
of the claim for indemnity, net of any increase in premium as a result of such
claim, and (ii) reduced (but not below zero) by an amount equal to the present
value of the tax benefit, if any, to the Indemnified Party or one or more of its
Affiliates resulting from the Loss that is the subject of the indemnity payment.


                                      -27-

                                   ARTICLE IX

                                  MISCELLANEOUS

      SECTION 9.01 Non-Survival of Representations and Warranties. The
representations and warranties made in this Agreement shall not survive the
termination of this Agreement or beyond the consummation of the Merger. This
Section 9.01 shall not limit any covenant or agreement of the parties which by
its terms contemplates performance after the Effective Time.

      SECTION 9.02 Entire Agreement; Assignment.

      (a) The Exhibits and Schedules identified in this Agreement are
incorporated herein by reference and made a part hereof. This Agreement
(including the documents and the instruments referred to herein), constitute the
entire agreement and supersede all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof
and thereof.

      (b) Neither this Agreement, nor any of the rights, interests or
obligations hereunder will be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
party, which will not be unreasonably withheld or delayed, except that Purchaser
may assign all or any of its rights to affiliates without the prior written
consent of the Company; provided, that no such assignment shall relieve the
assigning party of its obligations hereunder.

      SECTION 9.03 Binding Agreement. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns, provided, that, except as provided in Section 9.02(b), no
party may assign its rights and obligations under this Agreement without the
prior written consent of the other parties.

      SECTION 9.04 Severability. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity of enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other situation or in any other jurisdiction. If the final
judgment of a court of competent jurisdiction declares that any term or
provision hereof is invalid or unenforceable, the parties agree that the court
making the determination of invalidity or unenforceability shall have the power
to reduce the scope, duration, or area of the term or provision, to delete
specific words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is valid and enforceable and that comes
closest to expressing the intention of the invalid or unenforceable term or
provision, and this Agreement shall be enforceable as so modified after the
expiration of the time within which the judgment may be appealed.
