without any action on the part of Parent, Acquisition, the Company or the
holders of any of the following securities:

          (a)  each issued and outstanding share of common stock of Acquisition
shall be converted into one validly issued, fully paid and nonassessable share
of common stock, no par value per share, of the Surviving Corporation;

          (b)  each share of Company Common Stock owned or held in treasury by
the Company and each share of Company Common Stock owned by Acquisition or
Parent shall be

                                       2


canceled and retired without any conversion thereof and no payment or
distribution shall be made with respect thereto; and

          (c)  subject to the provisions of Section 1.8, each share of Company
Common Stock issued and outstanding immediately prior to the Effective Time
(other than shares of Company Common Stock canceled and retired in accordance
with Section 1.5(b) and any Dissenting Shares) shall be converted into the right
to receive $18.00 in cash per share, without interest (the "Merger
                                                            ------
Consideration"). As of the Effective Time, each share of Company Common Stock
- -------------
shall no longer be outstanding and shall automatically be canceled and retired,
and each holder of record of a certificate representing any such shares (a
"Certificate") shall cease to have any rights with respect thereto, other than
 -----------
the right to receive the Merger Consideration, in accordance with Section 1.8.

          (d)  Notwithstanding any provision of this Agreement to the contrary,
if required by the DGCL but only to the extent required thereby, shares of
Company Capital Stock that are issued and outstanding immediately prior to the
Effective Time and that are held by holders of such shares of Company Capital
Stock who have properly exercised appraisal rights with respect thereto in
accordance with Section 262 of the DGCL (the "Dissenting Shares") will not be
                                              -----------------
converted into the right to receive the Merger Consideration, and the holders of
such Dissenting Shares will be entitled to receive payment of the appraised
value of such shares of Company Capital Stock in accordance with the provisions
of such Section 262 of the DGCL unless and until such holders fail to perfect or
effectively withdraw or lose their rights to appraisal and payment under the
DGCL. If, after the Effective Time, any such holder fails to perfect or
effectively withdraws or loses such right, such shares of Company Capital Stock
will thereupon be treated as if they had been converted into and become
exchangeable for, at the Effective Time, the right to receive the Merger
Consideration, without any interest thereon. The Company shall (i) give Parent
prompt notice of any demands received by the Company for appraisals of shares of
Company Capital Stock and (ii) consult with and keep Parent informed, on an on-
going basis, regarding the status and negotiation of such demands. The Company
shall not make any payment or settlement offer, or agree to or effect any
settlement, prior to the Effective Time with respect to any such demand unless
Parent shall have consented in writing to such payment or settlement offer,
which consent shall not be unreasonably withheld.

          1.6  Company Stock Options; Warrants.
               -------------------------------

          (a)  As of the Effective Time, each outstanding option to purchase
shares of Company Common Stock under the Company Stock Plans (individually, a
"Company Stock Option" and collectively, the "Company Stock Options") shall
 --------------------                         ---------------------
be canceled and retired by virtue of the Merger and each holder of a Company
Stock Option shall cease to have any rights with respect thereto, other than the
right to receive the Option Consideration, if any, in accordance with this
Section 1.6(a). Except as set forth on Schedule 1.6, each holder of a Company
Stock Option, whether or not then exercisable, shall be entitled to receive in
cash an amount determined by multiplying (i) the excess, if any, of the Merger
Consideration over the exercise price per share provided in such Company Stock
Option, by (ii) the number of shares of Company Common Stock subject to such
Company Stock Option (such amount being hereinafter referred to as the "Option
                                                                        ------
Consideration"). Payment of the Option Consideration shall be made by the
- -------------
Company, subject to the terms and conditions of this Agreement, as soon as
practicable

                                       3


after consummation of the Merger and receipt by the Company of the surrendered
option agreement representing such Company Stock Option and a written
instrument, reasonably satisfactory to Parent, duly executed by the holder of
such Company Stock Option setting forth (x) a representation by such holder that
he or she is the owner of all options represented by such Company Stock Option
and (y) a confirmation of, and consent to, the cancellation of all of the
options represented by such Company Stock Option. All amounts payable pursuant
to this Section 1.6(a) shall be subject to any required withholding of taxes and
shall be paid without interest. At the Effective Time, the Company Stock Plans
shall terminate.

          (b)  As of the Effective Time, each outstanding Warrant shall be
canceled and retired by virtue of the Merger and each holder of a Warrant shall
cease to have any rights with respect thereto, other than the right to receive
the Warrant Consideration, if any, in accordance with this Section 1.6(b). Each
holder of a Warrant, whether or not then exercisable, shall be entitled to
receive in cash an amount determined by multiplying (i) the excess, if any, of
the Merger Consideration over the exercise price per share provided in such
Warrant, by (ii) the number of shares of Company Common Stock subject to such
Warrant (such amount being hereinafter referred to as the "Warrant
                                                           -------
Consideration"). Payment of the Warrant Consideration shall be made by the
- -------------
Company, subject to the terms and conditions of this Agreement, as soon as
practicable after consummation of the Merger and receipt by the Company of the
surrendered Warrant and a written instrument, reasonably satisfactory to Parent,
duly executed by the holder of such Warrant setting forth (x) a representation
by such holder that he or she is the owner of all rights represented by such
Warrant and (y) a confirmation of, and consent to, the cancellation of such
Warrant. All amounts payable pursuant to this Section 1.6(b) shall be subject to
any required withholding of taxes and shall be paid without interest.

          1.7  Adjustment of the Merger Consideration.  In the event that,
               --------------------------------------
prior to the Effective Date, any stock split, combination, reclassification or
stock dividend with respect to the Company Common Stock or the Company Preferred
Stock (collectively, the "Company Capital Stock"), any change or conversion of
                          ---------------------
Company Capital Stock into other securities or any other dividend or
distribution with respect to the Company Capital Stock (other than regular
quarterly dividends) should occur or, if a record date with respect to any of
the foregoing should occur, appropriate and proportionate adjustments shall be
made to the Merger Consideration, and thereafter all references to the Merger
Consideration shall be deemed to be to the Merger Consideration as so adjusted.

          1.8  Exchange Procedures; Stock Transfer Books.
               -----------------------------------------

          (a)  Prior to the Effective Time, Parent shall appoint a commercial
bank or trust company, which shall be reasonably satisfactory to the Company, to
act as paying agent hereunder (the "Paying Agent") for payment of the Merger
                                    ------------
Consideration upon surrender of a Certificate. Prior to or concurrently with the
Effective Time, Parent shall cause Acquisition or the Surviving Corporation, as
the case may be, to provide the Paying Agent with cash in an amount necessary to
pay for all the shares of Company Common Stock pursuant to Section 1.5(c). Such
amounts shall hereinafter be referred to as the "Exchange Fund."
                                                 -------------

          (b)  As soon as practicable after the Effective Time, Parent shall use
its reasonable efforts to cause the Paying Agent to send to each Person who was,
at the Effective

                                       4


Time, a holder of record of Certificates which shares were converted into the
right to receive the Merger Consideration pursuant to Section 1.5(c), a letter
of transmittal which (i) shall specify that delivery shall be effected and risk
of loss and title to such Certificates shall pass, only upon actual delivery
thereof to the Paying Agent, and (ii) shall contain instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate to the Paying Agent together with
such letter of transmittal, duly executed and completed in accordance with the
instructions thereto, and such other documents as may reasonably be required by
the Paying Agent, the holder of such Certificate shall promptly receive in
exchange therefor the Merger Consideration.

          (c)  If any Merger Consideration is to be paid to any Person other
than the registered holder of the Certificate surrendered in exchange therefor,
it shall be a condition to such exchange that such surrendered Certificate shall
be properly endorsed and otherwise in proper form for transfer and such Person
either (i) shall pay to the Paying Agent any transfer or other taxes required as
a result of the distribution of such cash payment to such Person, or (ii) shall
establish to the reasonable satisfaction of the Paying Agent that such tax has
been paid or is not applicable. Parent or the Paying Agent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of shares of Company Common Stock such amounts as Parent
or the Paying Agent 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 Parent or the
Paying Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Company Common
Stock in respect of which such deduction and withholding was made by Parent or
the Paying Agent. All amounts in respect of taxes received or withheld by Parent
shall be disposed of by Parent in accordance with the Code or such state, local
or foreign tax law, as applicable.

          (d)  As of the Effective Time, all shares of Company Common Stock
(other than shares of Company Common Stock to be canceled and retired in
accordance with Section 1.5(b) and any Dissenting Shares) issued and outstanding
immediately prior to the Effective Time shall cease to be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each holder
of any such shares shall cease to have any rights with respect thereto, except
the right to receive the Merger Consideration upon surrender of the Certificate
representing such shares in accordance with this Section 1.8. The Merger
Consideration paid upon the surrender of Certificates in accordance with the
terms of this Section 1.8 shall be deemed to have been delivered (and paid) in
full satisfaction of all rights pertaining to the Company Common Stock
previously represented by such Certificates.

          (e)  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 subject to such other reasonable
conditions as the Board of Directors of the Surviving Corporation may impose,
the Paying Agent shall issue in exchange for such lost, stolen or destroyed
Certificate, the Merger Consideration payable in respect thereof, pursuant to
this Agreement; provided, that Parent may, in its reasonable discretion and as
                --------
a condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed Certificate to deliver a bond in such sum as it may
reasonably require as indemnity against any claim that

                                       5


may be made against Parent, the Surviving Corporation or the Paying Agent with
respect to the Certificate alleged to have been lost, stolen or destroyed.

          (f)  At the Effective Time, the stock transfer books of the Company
shall be closed and thereafter there shall be no further registration of
transfers of shares of Company's capital stock on the records of the Company.

          (g)  The Paying Agent shall invest any cash included in the Exchange
Fund as directed by Parent on a daily basis; provided, that no such investment
                                             --------
or loss thereon shall affect the amounts payable to the Company's stockholders
pursuant to Section 1. Any interest and other income resulting from such
investments shall promptly be paid to Parent.

          1.9  Return of Exchange Fund.  Any portion of the Exchange Fund
               -----------------------
which remains undistributed to the former holders of Company Common Stock for
180 days after the Effective Time shall be delivered to Parent, upon its
request, and any such former holders who have not theretofore surrendered to the
Paying Agent their Certificates in compliance herewith shall thereafter look
only to Parent for payment of their claim for the Merger Consideration. None of
Parent, Acquisition, the Paying Agent or the Company shall be liable to any
former holder of Company Common Stock for any such cash held in the Exchange
Fund which is delivered to a public official pursuant to an official request
under any applicable abandoned property, escheat or similar law.

          1.10 Further Assurances.  If at any time after the Effective Time, the
               ------------------
Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments or assurances or any other acts or things are necessary,
desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in
the Surviving Corporation its right, title or interest in, to or under any of
the rights, privileges, powers, franchises, properties or assets of either the
Company or Acquisition, or (b) otherwise to carry out the purposes of this
Agreement, the Surviving Corporation and its proper officers and directors or
their designees shall be authorized to execute and deliver, in the name and on
behalf of either the Company or Acquisition, all such deeds, bills of sale,
assignments and assurances and do, in the name and on behalf of the Company or
Acquisition, all such other acts and things necessary, desirable or proper to
vest, perfect or confirm its right, title or interest in, to or under any of the
rights, privileges, powers, franchises, properties or assets of the Company or
Acquisition, as applicable, and otherwise to carry out the purposes of this
Agreement.

currently

                                       6


being used, and to perform its obligations under all Company Material Contracts,
except for those jurisdictions where the failure to be so organized, existing or
in good standing would, individually or in the aggregate, not reasonably be
expected to have a Material Adverse Effect on the Company. Each of the Company
and its Subsidiaries is duly qualified or licensed as a foreign corporation to
do business and is in good standing (with respect to jurisdictions which
recognize such concept) in each jurisdiction where the nature of its business or
the ownership, leasing or operation of its properties makes such qualification
or licensing necessary, except where the failure to be so qualified or licensed
and in good standing would, individually or in the aggregate, not have a
Material Adverse Effect on the Company. The Company has made available to Parent
prior to the execution of this Agreement complete and correct copies of its
certificate of incorporation and bylaws and the charter documents for each of
its Subsidiaries in each case, as amended to the date hereof.

                                      28


          5.2  No Solicitation by the Company.
               ------------------------------

          (a)  The Company shall not, nor shall it permit any of its
Subsidiaries, directors, officers, employees, attorneys, accountants or
financial advisors or other representative retained by it or any of its
Subsidiaries to, directly or indirectly through another Person, (i) solicit,
initiate or encourage (including by way of furnishing information), or take any
other action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal, or
(ii) participate in any discussions or negotiations regarding any Takeover
Proposal; provided, however, that if at any time prior to obtaining the Company
          --------  -------
Stockholder Approval at the Company Stockholders Meeting, the Board of Directors
of the Company determines in good faith, after consultation with outside
counsel, that the failure to provide such information or participate in such
negotiations or discussions would result in the breach of the fiduciary duties
of the Board of Directors of the Company to the Company's stockholders under
applicable Law, then the Company and its representatives may, in response to any
such written proposal that has been determined by it to be a Superior Proposal
or a Takeover Proposal that the Board of Directors of the Company concludes in
good faith that there is a reasonable likelihood that such Takeover Proposal
could constitute a Superior Proposal, which was not solicited by it or which did
not otherwise result from a breach of this Section 5.2(a), and subject to
providing at least three business days prior written notice of its decision to
take such action to Parent and compliance with Section 5.2(c), (x) furnish
information with respect to the Company and its Subsidiaries to any Person
making such a Superior Proposal or Takeover Proposal pursuant to a customary
confidentiality agreement containing terms no less restrictive than the terms of
the confidentiality agreement entered into between the Company and Parent or any
Affiliate thereof provided that a copy of all such information is delivered
simultaneously to Parent, after consultation with its outside counsel, and (y)
participate in discussions or negotiations regarding such Superior Proposal or
Takeover Proposal.

          (b)  Neither the Board of Directors of the Company nor any committee
thereof shall approve or recommend, or execute or enter into, any offer,
proposal, letter of intent, agreement in principle, merger agreement,
acquisition agreement, option agreement or other similar agreement (each, an
"Acquisition Agreement") related to any Takeover Proposal, other than any such
 ---------------------
agreement entered into concurrently with a termination pursuant to the next
sentence in order to facilitate such action. Notwithstanding the foregoing, in
response to a Superior Proposal, if the Board of Directors of the Company
determines in good faith, after consultation with outside counsel, that the
failure to do so would result in a breach of its fiduciary duties to the
Company's stockholders under applicable Law, the Board of Directors of the
Company may (subject to this and the following sentence) terminate this
Agreement in accordance with Section 7(d) (and concurrently with such
termination, cause the Company to enter into an Acquisition Agreement with
respect to such Superior Proposal), but only at a time that is after the third
business day following Parent's receipt of written notice advising Parent that
the Board of Directors of the Company is prepared to terminate this Agreement
and accept a Superior Proposal, specifying the material terms and conditions of
such Superior Proposal and identifying the Person making such Superior Proposal.
During the three business day period set forth in the immediately preceding
sentence, the Company shall provide an opportunity for Parent to make
adjustments in the terms and conditions of this Agreement as would lead the
Company to proceed with the transactions contemplated by this Agreement (as
amended by such

                                      29


adjustments); provided, however, that (i) any such adjustments shall be at the
              --------  -------
discretion of the parties at the time and (ii) any decision of the Company to
proceed with the Superior Proposal or the transactions contemplated by this
Agreement (as amended by such adjustments) is at the sole and absolute
discretion of the Company.

          (c)  In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 5.2, the Company shall promptly advise
Parent orally and in writing of any request for information or of any Takeover
Proposal or Superior Proposal, the material terms and conditions of such
request, Takeover Proposal or Superior Proposal and the identity of the Person
making such request, Takeover Proposal or Superior Proposal and keep Parent
informed of the status (including amendments or proposed amendments to) of such
request for information, Takeover Proposal or Superior Proposal on a continuing
basis.

          (d)  For purposes of this Agreement, (i) "Takeover Proposal" means,
                                                    -----------------
whether in the form of a proposal or intended proposal, a signed agreement or
completed action, as the case may be, any of the following: (A) a transaction or
series of transactions pursuant to which any Person (or group of Persons) other
than Parent and its Affiliates (a "Third Party") acquires or would acquire,
                                   -----------
directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the
Exchange Act) of more than 15% of the outstanding capital stock of the Company,
whether from the Company or pursuant to a tender offer or exchange offer or
otherwise; (B) any acquisition or proposed acquisition of, or business
combination with, the Company or any of its Subsidiaries, as the case may be, by
a merger or other business combination (including any so-called "merger-of-
equals" and whether or not the Company or any of its Subsidiaries is the entity
surviving any such merger or business combination); or (C) any merger,
reorganization, consolidation, recapitalization, liquidation, extraordinary
dividend, sale of assets or other similar transaction by or involving a Third
Party if, after giving effect thereto, the stockholders of the Company prior
thereto beneficially own less than 85% of the outstanding voting stock or
participating stock of the combined or ongoing entity (other than a transaction
contemplated by this Agreement); and (ii) a "Superior Proposal" means any bona
                                             -----------------
fide written proposal (on its most recently amended or modified terms, if
amended or modified) made by a Third Party to enter into a Takeover Proposal,
the effect of which would be that stockholders of the Company would beneficially
own less than 40% of the voting stock, common stock and participating stock of
the combined or ongoing entity, and which the Board of Directors of the Company
determines in its good faith judgment (after consultation with a financial
advisor of nationally recognized reputation) to be more favorable to the
Company's stockholders than the Merger, taking into account all relevant factors
(including whether, in the good faith judgment of the Board of Directors of the
Company, after consultation with a financial advisor of nationally recognized
reputation, the Third Party is reasonably able to finance the transaction and
after consideration of any proposed adjustments to this Agreement by Parent in
response to such Takeover Proposal as contemplated by Section 5.2(b)).

          (e)  Nothing contained in this Section 5.2 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act; provided, however, that in no event
                                             --------  -------
shall the Company or its Board of Directors take or agree or resolve to take any
action or make any recommendation inconsistent with the terms of this Agreement
unless the Company (i) determines that the tender offer to which its statement
pursuant to Rule 14e-2(a) relates constitutes a Superior Proposal, (ii)

                                      30


complies with the notice and waiting period provisions under Sections 5.2(a) and
(b), (iii) terminates this Agreement pursuant to Section 7(d) and (iv) pays the
Termination Fee to Parent as required by Sections 5.7(b) and 7(d).

- -------

          (a)  As soon as practicable following the date of this Agreement, the
Company shall prepare and file with the SEC the Company Proxy Statement with
respect to the Company Stockholders Meeting. The Company will use its reasonable
best efforts to cause the Company Proxy Statement to be mailed to the Company's
stockholders as promptly as practicable after the Company Proxy Statement is
cleared by the SEC. The Company shall provide Parent with a copy of the
preliminary Company Proxy Statement and all modifications thereto prior to
filing or delivery to the SEC and will consult with Parent in connection
therewith and consider in good faith comments provided by Parent regarding the
Company Proxy Statement. The Company will inform Parent, promptly after it
receives notice thereof, of any request by the SEC for the amendment of the
Company Proxy Statement or comments thereon and responses thereto or requests by
the SEC for additional information, and will furnish to Parent copies of all
correspondence between the Company or any of its representatives, on the one
hand, and the SEC or its staff, on the other hand, with respect to the Company
Proxy Statement, the Merger or any other filings in connection herewith or
therewith and will consult with Parent in connection therewith. If at any time
prior to the Effective Time any information relating to the Company or Parent,
or any of their respective affiliates, officers or directors, should be
discovered by the Company or Parent which should be set forth in an amendment or
supplement to the Company Proxy Statement, so that any of such document would
not include any misstatement of a material fact or omit to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, the party that discovers such
information shall promptly notify the other parties hereto and an appropriate
amendment or supplement describing such information shall be promptly filed with
the SEC and, to the extent required by law, disseminated to the stockholders of
the Company.

          (b)  The Company shall establish a record date (which will be as soon
as practicable following the date of this Agreement) for and take all necessary
steps under all applicable Laws, duly call, give notice of, convene and hold a
meeting of its stockholders (the "Company Stockholders Meeting") solely for the
                                  ----------------------------
purpose of obtaining the Company Stockholder Approval.

          (c)  Subject only to the Company's ability to terminate this Agreement
pursuant to Sections 5.2 and 7(d) hereof, the Board of Directors of the Company

transactions contemplated hereby and use its reasonable best efforts to obtain
Company Stockholder Approval.

          5.4  Reasonable Best Efforts.
               -----------------------

          (a)  Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use its reasonable best efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, and to
assist and cooperate with the other parties in

                                      31


doing, all things necessary, proper or advisable under applicable Laws to
consummate and make effective, in the most expeditious manner practicable, the
Merger and the other transactions contemplated by this Agreement, including (i)
the obtaining of all necessary actions or nonactions, waivers, consents and
approvals from Governmental Entities and the making of all necessary
registrations and filings and the taking of all steps as may be necessary to
obtain an approval or waiver from, or to avoid an action or proceeding by, any
Governmental Entity, (ii) the obtaining of all necessary consents, approvals or
waivers from third parties, (iii) the defending of any lawsuits or other legal
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated by this Agreement, including
seeking to have any stay or temporary restraining order entered by any court or
other Governmental Entity vacated or reversed, and (iv) the execution and
delivery of any additional instruments necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, this Agreement. Nothing
in this Section 5.4(a) shall be construed to require any party to participate in
any threatened or actual Legal Proceeding (other than Legal Proceedings to which
it is a party or subject or threatened to be made a party or subject) in
connection with the consummation of the transactions contemplated by this
Agreement unless such party shall consent in advance in writing to such
participation.

          (b)  In connection with and without limiting the foregoing, the
Company and Parent shall (i) take all action reasonably necessary to ensure that
no state takeover statute or similar statute or regulation is or becomes
applicable to the Merger, this Agreement, or any of the other transactions
contemplated by this Agreement and (ii) if any state takeover statute or similar
statute or regulation becomes applicable to the Merger, this Agreement, or any
other transaction contemplated by this Agreement, take all action reasonably
necessary to ensure that the Merger and the other transactions contemplated by
this Agreement may be consummated as promptly as practicable on the terms
contemplated by this Agreement and otherwise to minimize the effect of such
statute or regulation on the Merger and the other transactions contemplated by
this Agreement.

          5.5  Employee Benefit Plans; Existing Agreement.
               ------------------------------------------

          (a)  After the Effective Time, Parent shall cause the Surviving
Corporation to provide to the employees of the Company substantially similar
benefit plans, programs and arrangements provided to employees of the Company as
of the date hereof.

          (b)  With respect to each benefit plan, program, practice, policy or
arrangement maintained by the Surviving Corporation (the "Surviving Corporation
                                                          ---------------------
Plans") in which employees of the Company subsequently participate, for purposes
- -----
of determining vesting, accrual and entitlement to benefits, including for
severance benefits, pension benefits and vacation entitlement, service with the
Company (or predecessor employers to the extent the Company provides past
service credit) shall be treated as service with Surviving Corporation;
provided, that such service shall not be recognized to the extent that such
- --------
recognition would result in a duplication of benefits. Such service also shall
apply for purposes of satisfying any waiting periods, evidence of insurability
requirements, or the application of any pre-existing condition limitations. Each
Surviving Corporation Plan shall waive pre-existing condition limitations to the
same extent waived under the applicable Company Benefit Plan. Company employees
shall be given credit for amounts paid under a corresponding benefit plan during
the

                                      32


same period for purposes of applying deductibles, copayments and out-of-pocket
maximums as though such amounts had been paid in accordance with the terms and
conditions of the Surviving Corporation Plan for the plan year in which the
Effective Time occurs.

          5.6  Indemnification.
               ---------------

          (a)  From and after the Effective Time, Parent shall cause the
Surviving Corporation to, fulfill and honor in all respects (i) the obligations
of the Company to indemnify each Person who is or was a director or officer (an
"Indemnified Party") of the Company or any of its Subsidiaries pursuant to any
 -----------------
indemnification provisions of the Company's Certificate of Incorporation or
Bylaws as each is in effect on the date hereof, and (ii) any indemnification
agreements of the Company, as each is in effect on the date hereof, shall be
assumed by the Surviving Corporation in the Merger, without further action, as
of the Effective Time and shall survive the Merger and shall continue in full
force and effect in accordance with their terms, and Parent shall cause the
Surviving Corporation to honor all such rights. Without limitation to the
foregoing, Parent shall cause the Surviving Corporation to include and cause to
be maintained in effect in the Surviving Corporation's (or any successor's)
certificate of incorporation and bylaws after the Effective Time, provisions
regarding the elimination of liability of directors, indemnification of
officers, directors and employees and the advancement of expenses, which are, in
the aggregate, no less advantageous to the intended beneficiaries than the
corresponding provisions contained in the Company's Certificate of Incorporation
and Bylaws as in effect on the date hereof.

          (b)  For a period of six years after the Effective Time, Parent shall
cause to be maintained in effect the current officers' and directors' liability
insurance maintained by the Company with respect to the Indemnified Parties
(provided, that Parent may substitute therefor policies of at least the same
 --------
coverage and amounts containing terms and conditions which are no less
advantageous to the Indemnified Parties than such existing insurance) covering
acts or omissions occurring prior to the Effective Time; provided, that Parent
                                                         --------
shall not be required in order to maintain or procure such coverage to pay an
annual premium in excess of 175% of the current annual premium paid by the
Company for its existing coverage (the "Cap"); and provided, further, that if
                                        ---        --------  -------
existing coverage cannot be maintained or equivalent coverage cannot be
obtained, or can be obtained only by paying an annual premium in excess of the
Cap, Parent shall only be required to obtain as much coverage as can be obtained
by paying an annual premium equal to the Cap.

          (c)  This Section 5.6 shall survive the closing of all the
transactions contemplated hereby, is intended to benefit the Indemnified Parties
and their respective heirs and personal representative (each of which shall be
entitled to enforce this Section 5.6 against Parent and the Surviving
Corporation, as the case may be, as a third-party beneficiary of this
Agreement), and shall not be terminated or modified in such a manner to
adversely affect any Indemnified Party without the consent of such Indemnified
Party.

          5.7  Fees and Expenses.
               -----------------

          (a)  Except as provided in this Section 5.7, all fees and expenses
incurred in connection with the Merger, this Agreement, and the transactions
contemplated by this

                                      33


Agreement shall be paid by the party incurring such fees or expenses, whether or
not the Merger is consummated, except that Parent and the Company shall each pay
50% of the filing fees (i) for the pre-merger notification and report forms
under the HSR Act and (ii) associated with any filing made with the SEC.

          (b)  In the event that this Agreement is to be terminated by either
Parent or the Company pursuant to Section 7(c), then the Company shall pay
Parent by wire transfer of same day funds all fees and expenses (including, but
not limited to, fees of legal, accounting and other professionals and
consultants, investment banking and other advisory fees and expenses, fees and
expenses of banks and other financial institutions, print, travel and fees paid
to governmental and similar entities) incurred by Parent or any Affiliate of
Parent in connection with the transactions contemplated by this Agreement
(collectively, the "Parent Expenses") immediately prior to such termination, not
                    ---------------
to exceed $1,000,000. In the event that this Agreement is to be terminated by
the Company pursuant to Section 7(d), then the Company shall pay Parent a fee
equal to $7,000,000 (the "Termination Fee"), of which $5,000,000 shall be
                          ---------------
payable immediately prior to such termination and $2,000,000 shall be payable by
wire transfer of same day funds upon the earlier to occur of (i) 6 months from
the date of termination of this Agreement and (ii) the consummation of any such
Superior Proposal or other Takeover Proposal. The Company acknowledges that the
agreements contained in this Section 5.7(b) are an integral part of the
transactions contemplated by this Agreement and that, without these agreements,
Parent would not enter into this Agreement. Accordingly, if the Company fails
promptly to pay the amount due pursuant to this Section 5.7(b), and, in order to
obtain such payment, Parent commences a suit which results in a judgment against
the Company for the fee set forth in this Section 5.7(b), the Company shall pay
to Parent its costs and expenses (including reasonable attorneys' fees and
expenses) in connection with such suit, together with interest on the amount of
the fee at the prime rate of Bank of America in effect on the date such payment
was required to be made.

          5.8  Public Announcements. Parent and the Company will consult with
               --------------------
each other before issuing, and provide each other the opportunity to review,
comment upon and concur with, any press release or other public statements with
respect to the transactions contemplated by this Agreement, including the
Merger, and shall not issue any such press release or make any such public
statement prior to such consultation, except as either party may determine is
required by applicable Law (after consultation with its outside counsel), court
process or by obligations pursuant to any listing agreement with any national
securities exchange or national trading system. The parties agree that the
initial press release to be issued with respect to the transactions contemplated
by this Agreement shall be in the form heretofore agreed to by the parties.

          5.9  Stockholder Litigation. The Company shall give Parent the
               ----------------------
opportunity to participate in the defense of any stockholder litigation against
the Company and/or its directors relating to the transactions contemplated by
this Agreement. The Company shall not make any payment or settlement offer prior
to the Effective Time with respect to any such litigation unless Parent shall
have consented in writing to such payment or settlement, which consent shall not
be unreasonably withheld.

          5.10 Financing. Prior to the Closing, Parent and Acquisition will use
               ---------
their reasonable best efforts to enter into definitive agreements on terms and
conditions substantially

                                      34


in accordance with the Financing Commitments (the "Definitive Financing
                                                   --------------------
Agreements"). Parent and Acquisition will use their reasonable best efforts, and
- ----------
will cause their affiliates to use their reasonable best efforts, to comply with
the terms and satisfy the conditions of the Financing Commitments and the
Definitive Financing Agreements. Parent will furnish correct and complete copies
of the Definitive Financing Agreements to Company promptly upon their execution.
Parent will consummate the equity financing contemplated by the equity
commitment letters referred to in Section 3.5(iii) and (iv) on the Closing Date.
For purposes of this Section 5.10, "reasonable best efforts" shall not be deemed
