                          AGREEMENT AND PLAN OF MERGER

            This Agreement and Plan of Merger (this "Agreement") is made and
entered into as of the 18th day of February, 2004, by and among VAC-OS Holdings
LLC, a Delaware limited liability company ("Parent"), OS Merger Sub, Inc., a
Delaware corporation and wholly-owned subsidiary of Parent ("Merger Sub") and
OneSource Information Services, Inc., a Delaware corporation (the "Company").

                                   BACKGROUND

            A.    The Boards of Directors of Parent and Merger Sub and the
Special Committee and the Board of Directors of the Company (with Peter H. Kamin
abstaining) have each approved the merger of Merger Sub with and into the
Company, with the Company as the surviving corporation (the "Merger"), upon the
terms and subject to the conditions of this Agreement and in accordance with the
General Corporation Law of the State of Delaware (the "DGCL").

            B.    The Special Committee of the Board of Directors of the Company
(the "Special Committee") and the Board of Directors of the Company (with Peter
H. Kamin abstaining) have each approved this Agreement and the transactions
contemplated hereby and declared the advisability and resolved to recommend
approval of the Merger and approval and adoption of this Agreement by the
stockholders of the Company, subject to the terms of this Agreement.

                                      TERMS

            In consideration of the foregoing and the mutual representations,
warranties, covenants and agreements hereinafter set forth, the parties hereto
agree as follows:

                                    ARTICLE I

                                   THE MERGER

      1.1.  The Merger. Upon the terms and subject to the conditions hereof, and
in accordance with the provisions of the DGCL, at the Effective Time (as defined
in Section 1.2), Merger Sub shall be merged with and into the Company. As a
result of the Merger, the separate corporate existence of Merger Sub shall cease
and the Company shall continue as the surviving corporation of the Merger (the
"Surviving Corporation").

      1.2.  Effective Time; Closing. Concurrently with the Closing (as
hereinafter defined), the parties shall cause the Merger to be consummated by
filing with the Secretary of State of the State of Delaware (the "Secretary of
State") a certificate of merger (the "Certificate of Merger") in accordance with
Section 251 of the DGCL. The Merger shall become effective (the "Effective
Time") when the Certificate of Merger has been filed with the Secretary of State
or at such later time as shall be agreed upon by the parties and specified in
the Certificate of Merger. The closing of the transactions contemplated hereby
(the "Closing") shall be held at the offices of Dechert LLP, 200 Clarendon
Street, 27th Floor, Boston, Massachusetts, at 10:00 a.m. Boston

time on the third business day after satisfaction or (to the extent permitted by
law) waiver of those conditions set forth in Article VI (other than any of those
conditions that by their terms are to be satisfied at the Closing, but subject
to the satisfaction or (to the extent permitted by law) waiver of those
conditions), or at such other place or time or on such other date as Parent and
the Company may agree. The date on which the Closing takes place is referred to
herein as the "Closing Date").

      1.3.  Effects of the Merger. From and after the Effective Time, the Merger
shall have the effects set forth in the DGCL.

      1.4.  Certificate of Incorporation and Bylaws. At the Effective Time, the
Certificate of Incorporation and Bylaws of the Company, as in effect immediately
prior to the Effective Time, shall be the Certificate of Incorporation and
Bylaws, respectively, of the Surviving Corporation until thereafter changed or
amended as provided therein or by applicable law.

      1.5.  Directors and Officers of the Surviving Corporation. The directors
and officers of Merger Sub immediately prior to the Effective Time shall be the
directors and officers of the Surviving Corporation immediately following the
Effective Time.

                                   ARTICLE II

                            CONVERSION OF SECURITIES

      2.1.  Conversion of Capital Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of Parent, Merger Sub, the Company or
their respective stockholders:

            (a)   Subject to the other provisions of this Article II, each share
of Company Common Stock (as defined in Section 3.4) issued and outstanding
immediately prior to the Effective Time (other than any shares of Company Common
Stock to be cancelled pursuant to Section 2.1(b) and Dissenting Common Stock (as
defined in Section 2.3) shall be converted into and represent the right to
receive $8.40 in cash, without interest (the "Merger Consideration"). Subject to
the other provisions of this Article II, as of the Effective Time, each such
share of Company Common Stock shall, by virtue of the Merger, cease to be
outstanding and shall be cancelled and retired, and each holder of a certificate
representing any such shares shall thereafter cease to have any rights with
respect thereto except the right to receive the Merger Consideration.

            (b)   Each share of capital stock of the Company that is held in the
treasury of the Company or directly owned by the Company, any subsidiary of the
Company, Parent or Merger Sub immediately prior to the Effective Time shall be
cancelled and retired and shall cease to exist and no Merger Consideration or
any other payment shall be made in respect thereof.


                                      -2-

      2.2.  Exchange of Certificates.


            (a)   Paying Agent. Prior to the Effective Time, Parent shall
deposit, or shall cause to be deposited, with City National Bank or such other
paying agent as may be designated by Parent and reasonably acceptable to the
Company (the "Paying Agent"), for the benefit of the holders of Company Common
Stock, for exchange in accordance with this Section 2.2, cash in an amount
required to be paid pursuant to this Article II (such cash being hereinafter
referred to as the "Exchange Fund").

            (b)   Exchange Procedures. After the Effective Time (and in any
event within two business days), Parent shall cause the Paying Agent to mail to
each holder of record of a certificate or certificates which immediately prior
to the Effective Time represented outstanding shares of Company Common Stock
(the "Certificates") (i) a letter of transmittal in customary form which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Paying
Agent and shall be in such form and have such other provisions as Parent and the
Company may reasonably agree prior to the Effective Time and (ii) instructions
for effecting the surrender of the Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate for cancellation to the Paying
Agent, together with a duly executed letter of transmittal, and such other
documents as may reasonably be required by the Paying Agent, the holder of such
Certificate shall be entitled to receive in exchange therefor, the amount of
cash which the number of shares of Company Common Stock previously represented
by such Certificate shall have been converted into the right to receive pursuant
to this Article II and the Certificate so surrendered shall forthwith be
cancelled. No interest will be paid or accrued on the Merger Consideration. In
the event of a transfer of ownership of shares of Company Common Stock which is
not registered on the transfer records of the Company, payment of the Merger
Consideration may be issued to such transferee if the Certificate representing
such shares of Company Common Stock held by such transferee is presented to the
Paying Agent, accompanied by all documents required to evidence and effect such
transfer and to evidence that any applicable stock transfer taxes have been
paid.

            (c)   No Further Ownership Rights in Company Common Stock. The
Merger Consideration paid upon surrender of Certificates in accordance with the
terms hereof shall be deemed to have been paid in full satisfaction of all
rights pertaining to the shares of Company Common Stock formerly represented
thereby, and there shall be no further registration of transfers on the stock
transfer books of the Company of shares of Company Common Stock outstanding
immediately prior to the Effective Time. All Certificates presented to the
Surviving Corporation after the Effective Time for any reason shall be cancelled
against delivery of cash to the holder thereof as provided in this Section 2.2.

            (d)   Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to holders of Certificates 180 days after the
Effective Time shall be delivered to Parent, upon demand therefor, and holders
of Certificates who have not theretofore complied with this Section 2.2 shall
thereafter look only to Parent for the Merger Consideration payable in respect
of such shares of Company Common Stock, without any interest thereon.


                                      -3-

            (e)   No Liability. None of Parent, Merger Sub, the Surviving
Corporation or the Paying Agent shall be liable to any person in respect of any
cash from the Exchange Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any Certificates shall
not have been surrendered prior to two years after the Effective Time of the
Merger (or immediately prior to such earlier date on which any Merger
Consideration would otherwise escheat to or become the property of any
Governmental Authority (as defined in Section 3.5)), any such Merger
Consideration shall, to the extent permitted by Applicable Laws, become the
property of Parent, free and clear of all claims or interest of any person
previously entitled thereto.

            (f)   Investment of Exchange Fund. The Paying Agent shall invest the
cash in the Exchange Fund, as directed by Parent, on a daily basis. Any interest
and other income resulting from such investments shall be paid to Parent upon
termination of the Exchange Fund pursuant to this Article II.

            (g)   Missing Certificates. In the event any Certificate shall have
been lost, stolen or destroyed, upon the making of an affidavit of that fact and
providing an appropriate indemnity or surety bond by the person claiming such
Certificate to be lost, stolen or destroyed, the Paying Agent will deliver in
exchange for such lost, stolen or destroyed Certificate the applicable Merger
Consideration with respect thereto.

      2.3.  Dissenting Shares. Notwithstanding any provision of this Agreement
to the contrary, if and to the extent required by the DGCL, shares of Company
Common Stock which are issued and outstanding immediately prior to the Effective
Time and which are held by holders of such shares of Company Common Stock who
have properly exercised appraisal rights with respect thereto (the "Dissenting
Common Stock") in accordance with Section 262 of the DGCL, shall not be
converted into the right to receive the Merger Consideration, and holders of
such shares of Dissenting Common Stock shall be entitled to receive payment of
the appraised value of such shares of Dissenting Common Stock in accordance with
the provisions of Section 262 of the DGCL unless and until such holders fail to
perfect or effectively withdraw or otherwise 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 Dissenting
Common Stock shall thereupon be treated as if they had been converted into and
have become exchangeable for, at the Effective Time, the right to receive the
Merger Consideration, without any interest thereon. The Company shall give
Parent prompt notice of any demands received by the Company for appraisals of
shares of Dissenting Common Stock. The Company shall not, except with the prior
written consent of Parent, make any payment with respect to any demands for
appraisals or offer to settle or settle any such demands, and Parent shall have
the right to participate in all negotiations and proceedings with respect to
such demands.

      2.4.  Stock Option Plans. As soon as practicable following the date of
this Agreement, but in any event no later than thirty (30) days before the
Closing Date, the board of directors of the Company (or, if appropriate, any
committee administering the stock option plans of the Company) shall adopt such
resolutions or use all reasonable efforts to take such other actions as are
required to provide that each then outstanding stock option (whether or not
vested) to purchase shares of Company Common Stock (each, a "Company Stock
Option") heretofore


                                      -4-

granted under any stock option or other stock-based incentive plan, program or
arrangement of the Company (collectively, the "Company Stock Option Plans")
shall be cancelled immediately prior to the Effective Time in exchange for
payment of an amount in cash equal to the product of (i) the number of
unexercised shares of Company Common Stock subject to such Company Stock Option
immediately prior to the Effective Time and (ii) the excess, if any, of the
Merger Consideration over the per share exercise price of such Company Stock
Option.

      2.5.  Company ESPP Plans. As soon as practicable following the date of
this Agreement, but in any event no later than February 29, 2004, the board of
directors of the Company (or, if appropriate, a committee administering the
stock plans of the Company) shall adopt such resolutions or use all reasonable
efforts to take such other actions as are required to terminate the Company's
1999 Employee Stock Purchase Plan (the "Company ESPP") effective as of February
29, 2004 so that no more stock options may be granted thereunder on or after
March 1, 2004. Stock options granted under the Company ESPP with respect to the
Payment Period (as such term is defined in the Company ESPP) that ends on
February 29, 2004 shall be exercised in accordance with the terms of the Company
ESPP and subject to the terms of the Company ESPP.

      2.6.  Withholding Rights. 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 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 Internal Revenue Code of 1986, as amended, (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 Company Common Stock in respect of which such deduction and withholding was
made by Parent or the Paying Agent.

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

            In order to induce Parent to enter into this Agreement, the Company
hereby represents and warrants to Parent as follows:

      3.1.  Organization and Standing. Each of the Company and each subsidiary
(as defined in Section 8.3) of the Company is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation with full corporate power and authority to own, lease, use and
operate its properties and to conduct its business as and where now owned,
leased, used, operated and conducted. Each of the Company and each subsidiary of
the Company is duly qualified to do business and in good standing in each
jurisdiction in which the nature of the business conducted by it or the property
it owns, leases or operates requires it to so qualify, except where the failure
to be so qualified or in good standing in such jurisdiction individually or in
the aggregate would not reasonably be expected to have a Material Adverse Effect
(as defined in Section 8.3) on the Company. The Company is not in default in the
performance, observance or fulfillment of any provision of its Certificate of
Incorporation or its


                                      -5-

Bylaws, each as in effect on the date hereof (the "Company Certificate" and the
"Company Bylaws," respectively). The Company has heretofore furnished to Parent
a complete and correct copy of the Company Certificate and the Company Bylaws.

      3.2.  Subsidiaries. The Company does not own, directly or indirectly, any
equity or other ownership interest in any corporation, partnership, joint
venture or other entity or enterprise, except for the subsidiaries and other
entities set forth in Section 3.2 to the Company Disclosure Schedule. Except as
set forth in Section 3.2 to the Company Disclosure Schedule, the Company is not
subject to any obligation or requirement to provide funds to or make any
investment (in the form of a loan, capital contribution or otherwise) in any
entity or enterprise that is not wholly-owned by the Company. Except as set
forth in Section 3.2 to the Company Disclosure Schedule, the Company owns
directly or indirectly each of the outstanding shares of capital stock (or other
ownership interests having by their terms ordinary voting power to elect a
majority of directors or others performing similar functions with respect to
such subsidiary) of each of the Company's subsidiaries, free and clear of all
liens, pledges, security interests, claims or other encumbrances. Each of the
outstanding shares of capital stock of each of the Company's subsidiaries is
duly authorized, validly issued, fully paid and nonassessable. Other than as set
forth in Section 3.2 to the Company Disclosure Schedule, there are no
outstanding subscriptions, options, warrants, puts, calls, agreements,
understandings, claims or other commitments or rights of any type relating to
the issuance, sale, repurchase or transfer of any capital stock or other
securities of any subsidiary of the Company, nor are there outstanding any
securities which are convertible into or exchangeable for any shares of capital
stock or other securities of any subsidiary of the Company, and neither the
Company nor any subsidiary of the Company has any obligation of any kind to
issue any additional shares of capital stock or other securities of any
subsidiary of the Company or to pay for or repurchase any shares of capital
stock or other securities of any subsidiary of the Company or any predecessor
thereof.

      3.3.  Corporate Power and Authority. The Company has all requisite
corporate power and authority to enter into and deliver this Agreement, to
perform its obligations hereunder and, subject to approval of the Merger and the
transactions contemplated hereby by the stockholders of the Company, to
consummate the transactions contemplated by this Agreement. The execution,
delivery and performance of this Agreement by the Company have been duly and
validly authorized by all necessary corporate action on the part of the Company,
other than the approval of this Agreement by the holders of a majority of the
outstanding shares of Company Common Stock entitled to vote in accordance with
the DGCL and the Company's Certificate of Incorporation and Bylaws (the
"Requisite Company Vote"). The Special Committee and the Board of Directors of
the Company have each approved this Agreement and the transactions contemplated
hereby and declared the advisability thereof. This Agreement has been duly
executed and delivered by the Company and constitutes the legal, valid and
binding obligation of the Company enforceable against it in accordance with its
terms.

      3.4.  Capitalization of the Company. The authorized capital stock of the
Company consists solely of (a) 35,000,000 shares of common stock, par value
$0.01 per share ("Company Common Stock"), of which 11,635,932 shares were issued
and outstanding as of January 31, 2004 and (b) 1,000,000 shares of preferred
stock, par value $0.01 per share, 100,000 shares of which have been designated
as Series A Junior Participating Preferred Stock, and none of which


                                      -6-

are issued and outstanding on the date hereof. As of January 31, 2004, (i)
1,085,847 shares of Company Common Stock remain available for issuance pursuant
to the Company Stock Option Plans and 2,523,027 shares of Company Common Stock
are subject to outstanding Company Stock Options and (ii) 1,651,521 shares of
Company Common Stock were held by the Company in its treasury. Except as set
forth in this Section 3.4 and the preferred stock purchase rights (the "Rights")
issued pursuant to the Rights Agreement dated as of October 7, 2003 between the
Company and American Stock Transfer & Trust Company, as amended by Amendment No.
1 to the Rights Agreement dated as of February 17, 2004 (the "Rights Plan"),
there are not any options, warrants, calls, subscriptions, convertible
securities or other rights, or other agreements obligating the Company to issue,
transfer or sell any shares of capital stock of, or other equity interests in,
the Company. All issued and outstanding shares of Company Common Stock are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights. Except as set forth in Section 3.4 to the Company Disclosure Schedule,
there are no outstanding obligations of the Company or any of its subsidiaries
to repurchase, redeem or otherwise acquire any shares of capital stock of, or
other equity interests in, the Company.

      3.5.  Conflicts; Consents and Approvals. Except as set forth in Section
3.5 to the Company Disclosure Schedule and, in the case of (b), (c) and (d), for
any of the following that would not, individually or in the aggregate,

      3.6.  No Material Adverse Effect. Except as specifically disclosed in the
Company SEC Documents (as defined in Section 3.7) filed with the Commission
prior to the date of this Agreement, since December 31, 2002, there has been no

condition of the Company which individually or in the aggregate would reasonably
be expected to have a Material Adverse Effect on the Company.

      3.7.  Company SEC Documents. The Company has timely filed with the
Commission all forms, reports, schedules, statements and other documents
required to be filed by it since December 31, 1998 under the Securities Exchange
Act of 1934, as amended (together with the rules and regulations thereunder, the
"Exchange Act") or the Securities Act of 1933, as amended, (the "Securities
Act") (such documents, as supplemented and amended since the time of filing,
collectively, the "Company SEC Documents"). The Company SEC Documents,
including, without limitation, any financial statements or schedules included or
incorporated by reference therein, at the time filed (and, in the case of
registration statements and proxy statements, on the dates of effectiveness and
the dates of mailing, respectively) (a) did not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and (b) complied in
all material respects with the applicable requirements of the Exchange Act and
the Securities Act, as the case may be. Except as set forth in Section 3.7 of
the Company Disclosure Schedule, the financial statements of the Company
included in the Company SEC Documents at the time filed (and, in the case of
registration statements and proxy statements, on the dates of effectiveness and
the dates of mailing, respectively) complied as to form in all material respects
with applicable accounting requirements and with the published rules and
regulations of the Commission with respect thereto, were prepared in accordance
with generally accepted accounting principles applied on a consistent basis
during the periods involved (except as may be indicated in the notes thereto or,
in the case of unaudited statements, as permitted by Form 10-Q of the
Commission), and fairly present (subject, in the case of the unaudited interim
financial statements, to normal, recurring year-end audit adjustments consistent
with past practice), in all material respects, the consolidated financial
position of the Company and its consolidated subsidiaries as at the dates
thereof and the consolidated results of their operations and cash flows for the
periods then ended. No subsidiary of the Company is subject to the periodic
reporting requirements of the Exchange Act or required to file any form, report
or other document with the Commission, the Nasdaq Stock Market, Inc., any stock
exchange or any other comparable Governmental Authority.

      3.8.  Taxes. Except as set forth in Section 3.8 to the Company Disclosure
Schedule and except for such matters that would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company:


                                      -8-

            (a)   The Company and its subsidiaries (i) have duly filed all Tax
Returns (as defined in Section 3.8(d)) (including, but not limited to, those
filed on a consolidated, combined or unitary basis) required to have been filed
by the Company or its subsidiaries, all of which Tax Returns are true and
correct; (ii) have within the time and manner prescribed by Applicable Law paid
all Taxes (as defined in Section 3.8(d)), required to be paid in respect of the
periods covered by such Tax Returns or otherwise due to any Governmental
Authority; (iii) have established in accordance with their normal accounting
practices and procedures, accruals and reserves that are adequate for the
payment of all Taxes not yet due and payable; (iv) are not delinquent in the
payment of any Tax; and (v) have not received written notice of any deficiencies
for any Tax from any Governmental Authority against the Company or any of its
subsidiaries, which deficiency has not been satisfied. Neither the Company nor
any of its subsidiaries is the subject of any currently ongoing Tax audit.
Neither the Company nor any of its subsidiaries has requested, or been granted,
an extension of time in which to file Tax Returns or pay Taxes, which extension
has continuing effect. With respect to any taxable period ended prior to January
1, 1999, all federal income Tax Returns including the Company or any of its
subsidiaries have been audited by the Internal Revenue Service or are closed by
the applicable statute of limitations. Neither the Company nor any of its
Subsidiaries is or may be subject to any "accuracy-related penalty" under Code
Section 6662 (or any comparable provision of state, local or foreign law) with
respect to Tax periods for which Tax Returns have been filed. Neither the
Company nor any of its Subsidiaries is subject to any extension of the statute
of limitations for collection of Taxes under Code Section 6501 (or any
comparable provision of state, local, or foreign law) from the minimum period
allowed by law as a result of failure to accurately complete, or to disclose any
items in, a Tax Return. There are no liens with respect to Taxes upon any of the
properties or assets, real or personal, tangible or intangible, of the Company
or any of its subsidiaries (other than liens for Taxes not yet due). No claim
has ever been made in writing by a Governmental Authority in a jurisdiction
where the Company or its subsidiaries do not file Tax Returns that the Company
or any of its subsidiaries is or may be subject to taxation by that
jurisdiction.

            (b)   Neither the Company nor any of its subsidiaries is obligated
by any contract, agreement or other arrangement to indemnify any other person
with respect to Taxes. Neither the Company nor any of its subsidiaries is now or
has ever been a party to or bound by any contract, agreement or other
arrangement (whether or not written and including, without limitation, any
arrangement required or permitted by Applicable Law (including pursuant to
Treasury Regulation Section 1.1502-6 or any analogous provision of state, local
or foreign law)) that (i) requires the Company or any of its subsidiaries to
make any Tax payment to or for the account of any other person, (ii) affords any
other person the benefit of any net operating loss, net capital loss, investment
Tax credit, foreign Tax credit, charitable deduction or any other credit or Tax
attribute which could reduce Taxes (including, without limitation, deductions
and credits related to alternative minimum Taxes) of the Company or any of its
subsidiaries, or (iii) requires or permits the transfer or assignment of income,
revenues, receipts or gains to the Company or any of its subsidiaries from any
other person, other than payments made to the Company and its subsidiaries in
the ordinary course of business. Neither the Company nor any of its subsidiaries
will be required to include any item of income in, or exclude any item of
deduction from, taxable income for any taxable period (or portion thereof)
ending after the Closing Date as a result of any (i) change in method of
accounting for a taxable period ending on


                                      -9-

or prior to the Closing Date; (ii) "closing agreement" as described in Code
Section 7121 (or any comparable provision of state, local, or foreign law);
(iii) intercompany transactions or any excess loss account described in Treasury
Regulations under Code Section 1502 (or any comparable provision of state,
local, or foreign law); (iv) installment sale or open transaction disposition
made on or prior to the Closing Date; or (v) prepaid amount received on or prior
to the Closing Date. Neither the Company nor any of its subsidiaries is a party
to any "gain recognition agreement" as described in Treasury Regulation Section
1.367(a)-8 (or any analogous provision of foreign law). Neither the Company nor
any of it subsidiaries is a party to any transaction that is or was (i) since
January 1, 1998, intended to qualify under Code sections 355 or 368 other than
as a recapitalization pursuant to Code Section 368(a)(1)(E), or (ii) required to
be reported as a "listed transaction" to any Governmental Authority under
Treasury Regulation Section 1.6011-4(b)(2) (or any comparable or predecessor
provision of federal, state, local or foreign law).

            (c)   The Company and its subsidiaries have withheld and paid all
Taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, creditor, stockholder or other
third party.

            (d)   For purposes of this Agreement, (i) "Tax" (and, with
correlative meaning, "Taxes") means any federal, state, local or foreign income,
gross receipts, property, sales, use, license, excise, franchise, employment,
payroll, premium, withholding, alternative or added minimum, ad valorem,
inventory, transfer or excise tax, or any other tax, custom, duty, governmental
fee or other like assessment or charge of any kind whatsoever, together with any
interest or penalty, imposed by any Governmental Authority, and (ii) "Tax
Return" means any return, report or similar statement required to be filed with
respect to any Tax (including any attached schedules), including, without
limitation, any information return, claim for refund, amended return or
declaration of estimated Tax.

      3.9.  Compliance with Law. Except as specifically disclosed in the Company
SEC Documents filed with the Commission prior to the date hereof, the Company is
in compliance with all applicable laws, statutes, orders, rules, regulations,
policies or guidelines promulgated, or judgments, decisions or orders entered,
by any Governmental Authority, (all such laws, statutes, orders, rules,
regulations, policies, guidelines, judgments, decisions and orders,
collectively, "Applicable Laws"), relating to the Company or its business or
properties, except where the failure to be in compliance with such Applicable
Laws individually or in the aggregate would not reasonably be expected to have a
Material Adverse Effect on the Company. Except as specifically disclosed in the
Company SEC Documents filed with the Commission prior to the date hereof, no
investigation or review by any Governmental Authority with respect to the
Company is pending, or, to the knowledge of the Company, threatened, nor has any
Governmental Authority indicated in writing an intention to conduct the same,
other than those the outcome of which would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect on the
Company.

            "Withdrawal Liability" means liability to a Multiemployer Plan (as
defined in Section 3.16) as a result of a complete or partial withdrawal from
such Multiemployer Plan, as those terms are defined in Part I of Subtitle E of
Title IV of ERISA.

            (b)   With respect to each Company Plan, the Company has provided to
Parent a true, correct and complete copy of (where applicable): (i) each writing
constituting a part of such Company Plan, including without limitation all plan

            (c)   The Company Plans which are "employee pension benefit plans"
within the meaning of Section 3(2) of ERISA and which are intended to meet the
qualification requirements of Section 401(a) of the Code, or Sections 401(k) or
401(m) of the Code, as applicable (each a "Qualified Plan"), now meet, and at
all times since their inception have met, the requirements for such
qualification in all material respects, and the related trusts are now, and at
all times since their inception have been, exempt from taxation under Section
501(a) of the Code in all material respects. Except as set forth on Section
3.15(c) of the Company Disclosure Schedule, each of the Qualified Plans has
received a favorable determination from the Internal Revenue Service, and no
such determination letter has been revoked nor, are there any existing
circumstances why any such determination letter should be revoked nor has any
Qualified Plan


                                      -16-

been amended since the date of its most recent determination letter in any
respect which would adversely affect the qualified status of any Company
Qualified Plan or the related trust.

            (d)   No Company Plans are now or at any time have been subject to
Part 3, Subtitle B of Title I of ERISA or Title IV of ERISA. All contributions

respect to insurance policies funding any Company Plan, before the date hereof
have been made or paid in full on or before the final due date thereof. All
contributions with respect to the period ending at the Effective Time will have

Company's balance sheet or are disclosed in Section 3.15(d) of the Company
Disclosure Schedule.

            (e)   The Company and its subsidiaries have materially complied, and
are now in material compliance, with all applicable provisions of ERISA and the
Code and all Applicable Laws relating to employees and employee benefits. Each
Company Plan has been established and operated in material compliance with its

circumstances that individually or in the aggregate would reasonably be expected
to give rise to, any requirement for the posting of security with respect to a
Company Plan or the imposition of any lien on the assets of the Company or any
of its subsidiaries under ERISA or the Code. The Company and its subsidiaries
are each in material compliance with all Applicable Laws respecting employment.

            (f)   Except as set forth in Section 3.15(f) to the Company
Disclosure Schedule, no Company Plan is a "multiemployer plan" within the
meaning of Section 4001(a)(3) of ERISA (a "Multiemployer Plan") or a plan that
has two or more contributing sponsors at least two of whom are not under common
control, within the meaning of Section 4063 of ERISA (a "Multiple Employer
Plan"), nor has the Company or any of its subsidiaries or any of their
respective ERISA Affiliates, at any time within six years before the date
hereof, contributed to or been obligated to contribute to any Multiemployer Plan
or Multiple Employer Plan. With respect to each Multiemployer Plan: (i) neither
the Company nor any of its ERISA Affiliates has incurred any Withdrawal
Liability that has not been satisfied in full; (ii) neither the Company nor any
ERISA Affiliate has received any notification, nor has any reason to believe,
that any such plan is in reorganization, is insolvent, or has been terminated,
or could reasonably be expected to be in reorganization, to be insolvent, or to
be terminated; and (iii) no circumstances exist which individually or in the
aggregate could reasonably be expected to result in Withdrawal Liability with
respect to a Plan.

            (g)   There does not now exist, and there are no existing
circumstances that individually or in the aggregate would reasonably be expected
to result in, any material Controlled Group Liability. Without limiting the
generality of the foregoing, neither the Company nor any of its subsidiaries nor
any of their respective ERISA Affiliates has engaged in any transaction
described in Section 4069 or Section 4204 of ERISA.

4980B of the Code or Part 6 of Title I of ERISA or similar state laws and except
as set forth in Section 3.15(h) to the Company Disclosure Schedule, neither the
Company nor any of its subsidiaries has any material liability for life, health,
medical or other welfare benefits to former employees or beneficiaries or
dependents thereof.

            (i)   Except as disclosed in Section 3.15(i) to the Company
Disclosure Schedule, neither the execution and delivery of this Agreement nor
the consummation of the transactions contemplated hereby will result in, or
constitute an event which, with the passage of time or the giving of notice or
both will result in, cause the accelerated vesting or delivery of, or increase
the amount or value of, any payment or benefit to any employee, officer,
director or consultant of the Company or any of its subsidiaries. Without
limiting the generality of the foregoing, except as set forth in Section 3.15(i)
to the Company Disclosure Schedule, no amount paid or payable by the Company or
any of its subsidiaries or affiliates in connection with the transactions
contemplated hereby either solely as a result thereof or as a result of such
transactions in conjunction with any other events will be an "excess parachute
payment" within the meaning of Section 280G of the Code. Except as disclosed in
Section 3.15(i) of the Company Disclosure Schedule, there is no agreement, plan,
arrangement or other contract covering any employee or independent contractor or
former employee or independent contractor of the Company that, considered
individually or considered collectively with any other such Contracts, will, or
could reasonably be expected to, give rise directly or indirectly to the payment
of any amount that would not be deductible pursuant to Section 280G or Section
162 of the Code nor will the Company be required to "gross up" or otherwise
compensate any such person because of the imposition of any excise tax as a
payment to such person.

            (j)   Except as disclosed in Section 3.15(j) to the Company
Disclosure Schedule, there are no pending, or to the knowledge of the Company
threatened, Actions (other than claims for benefits in the ordinary course) with
respect to the Company Plans.

a list of each employment, consulting, severance or similar agreement under
which the Company or any of its subsidiaries is or could become obligated to
provide compensation or benefits in excess of $75,000, and the Company has
provided to Parent a copy of each such agreement. Except for the severance
amounts listed under the heading "At Will Severance Amounts" on Section 3.15(k)
of the Company Disclosure Schedule, the aggregate amount of payments which the
Company and its subsidiaries is or could become obligated to pay pursuant to
existing agreements, arrangements and benefit plans to its officers, directors,
employees and consultants for change-in-control, success fee, stay-put,
retention or similar fees and bonuses does not exceed $1,351,000.

            (l)   No employer securities, employer real property or other
employer property is included in the assets of any Company Plan.

            (m)   No event has occurred, and there exists no condition or set of
circumstances in connection with any Plan, under which the Parent, Merger Sub,
the Company or any of its subsidiaries, nor any employee of the foregoing,
directly or indirectly, could


                                      -18-

reasonably be expected to be subject to any risk of material liability under
Sections 409 or 502 of ERISA or Section 4975 of the Code.

            (n)   Company maintains policies or practices on the proper
classification for all employees, leased employees, consultants and independent
contracts, for all purposes (including, without limitation, for all tax purpose

bound are valid and binding obligations of the Company and, to the knowledge of
the Company, the valid and binding obligation of each other party thereto except
such Contracts which if not so valid and binding would not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect on the
Company. Neither the Company nor, to the knowledge of the Company, any other
party thereto is in violation of or in default in respect of, nor has there
occurred an event or condition which with the passage of time or giving of
notice (or both) would constitute a default under or permit the termination of,
any such Contract except such violations or defaults under or terminations

have a Material Adverse Effect on the Company. Set forth in Section 3.16(m) to

of the foregoing described in this paragraph (ii) or to the matters described in
paragraph (i) of this Section 5.1(a), provided that it shall afford the Company
a reasonable opportunity to participate therein, and provided, further, that
nothing in this sentence shall affect the parties' rights and obligations
contained in the third, fourth and fifth sentences of Section 5.1(a)(i).
Notwithstanding the foregoing or any other provision of this Agreement, nothing
in this Section 5.1(a) shall limit a party's right to terminate this Agreement
pursuant to Section 7.1, so long as such party has up to then complied in all
material respects with its obligations under this Section 5.1(a). Each of Parent
and the Company shall use its best efforts to take such action as may be
required to cause the expiration or early termination of the notice period under
the HSR Act or other Antitrust Laws with respect to such transactions as
promptly as possible after the execution of this Agreement.

                  (iii) Each of the parties shall use its 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 doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Merger and the other transactions contemplated by this
Agreement, including (A) the obtaining of all other necessary actions or
nonactions, waivers, consents, licenses, permits, authorizations, orders and
approvals from Governmental Authorities and the making of all other necessary
registrations and filings (including other filings with Governmental
Authorities, if any), subject to the limitations of Section 5.1(a)(ii), (B) the
obtaining of all consents, approvals or waivers from third parties related to or
required in connection with the Merger that are necessary to consummate the
Merger and the transactions contemplated by this Agreement or required to

to or after the Effective Time, (C) the preparation of the Proxy Statement and
(D) the execution and delivery of any additional instruments necessary to
consummate the transaction contemplated by, and to fully carry out the purposes
of, this Agreement.

                  (iv)  Notwithstanding anything to the contrary in this
Agreement, neither Parent nor the Company shall be required to (i) hold separate
(including by trust or otherwise) or divest any of their respective businesses
or assets or (ii) waive any of the conditions to the Merger set forth in Article
VI of this Agreement as they apply to such party.

            (b)   Public Announcements. Each of the parties agrees that it shall
not, nor shall any of their respective affiliates, issue or cause the
publication of any press release or other public announcement with respect to
the Merger, this Agreement or the other transactions contemplated hereby without
the prior approval of the other party, except such disclosure as may be required
by law or by any listing agreement with the Nasdaq Stock Market, Inc., a
national securities exchange; provided, if such disclosure is required by law or
any such listing agreement, such disclosure may not be made without prior
consultation of the other parties.

            (c)   Taking of Necessary Action; Further Action. Each of Parent,
Merger Sub and the Company will take all such reasonable and lawful action as
may be necessary or appropriate in order to effectuate the Merger in accordance
with this Agreement as promptly as possible. If at any time after the Effective
Time, any such further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub immediately prior to the Effective Time are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.

      5.2.  Covenants of Parent.

            (a)   Indemnification; Directors' and Officers' Insurance.

                  (i)   Parent and the Company agree that all rights to
indemnification or advancement of expenses and director exculpation, and all
limitations with respect thereto, existing in favor of any Indemnified Person,
as provided in the Company Certificate or the Company Bylaws, shall survive the
Merger and shall continue in full force and effect for six years, without any
amendment thereto; provided, however, that in the event any Claim is asserted or
made, any determination required to be made with respect to whether an
Indemnified Person's conduct complies with the standards set forth under the
DGCL, the Company Certificate or the Company Bylaws or any such agreement, as
the case may be, shall be made by independent legal counsel selected by such
Indemnified Person and reasonably acceptable to Parent. For a period of six
years after the Effective Time, Parent shall cause the Surviving Corporation to
indemnify, defend and hold harmless (and make advances for expenses as incurred
to) all past and present officers and directors of the Company and of its
Subsidiaries to the same extent and in the same manner such persons are entitled
to indemnification and advancement of expenses as of the date of this Agreement
(to the extent consistent with applicable law) by the Company pursuant to the
DGCL, the Company Certificate or the Company Bylaws for acts or omissions
occurring at or prior to the Effective Time. For a period of six years after the
Effective Time, Parent shall cause the Surviving Corporation to perform all of
the obligations set forth in the Company Charter and the Company Bylaws.

                  (ii)  Parent shall maintain the Company's existing directors'
and officers' liability insurance policy ("D&O Insurance") for a period of not
less than six years after the Effective Time; provided, however, that Parent may
substitute therefor policies of substantially similar coverage and amounts (with
carriers comparable to the Company's existing carriers) containing terms no less
advantageous to such former directors or officers; provided further that if the
existing D&O Insurance expires or is canceled during such period, Parent shall
use its reasonable efforts to obtain substantially similar D&O Insurance;
provided further that Parent and the Company shall not be required pursuant to
its obligations under this Section 5.2(a)(ii) to pay in excess of an aggregate
amount of $950,000, but in such case shall purchase as much coverage as possible
for such amount.

            (b)   Section 16 Matters. Prior to the Effective Time, Parent and
the Company shall take all such steps as may be required to cause the Merger and
the transactions

                                      -26-

contemplated hereby, including any dispositions of Company Common Stock
(including derivative securities with respect to the Company Common Stock) by
each individual who is subject to the reporting requirements of Section 16(a) of
the Exchange Act with respect to the Company to be exempt under Rule 16b-3
promulgated under the Exchange Act, such steps to be taken in accordance with
the No-Action Letter dated January 12, 1999 issued by the SEC regarding such
matters.

            (a)   The Company Stockholders Meeting. The Company shall take all
action in accordance with the federal securities laws, the DGCL and the Company
Certificate and the Company Bylaws necessary to convene a special meeting of the
stockholders of the Company entitled to vote (the "Company Stockholders
Meeting") to be held and completed on the earliest practicable date following
the execution of this Agreement and determined by Parent, subject to the consent
of the Company (which shall not be unreasonably withheld), to consider and vote
upon approval of the Merger, this Agreement and the transactions contemplated
hereby; provided, however, that the Company shall not hold the Company
Stockholders Meeting until any applicable waiting periods (and any extensions
thereof, including any written commitment to an HSR Authority to defer or delay
consummation of the Merger notwithstanding expiration of such waiting periods)
under the HSR Act relating to the Merger and the transactions contemplated by
this Agreement shall have expired or been terminated.

            (b)   SEC Filings. The Company shall, in accordance with applicable
law, as soon as practicable following the execution of this Agreement: (i)
prepare and file with the Securities and Exchange Commission (the "SEC") a proxy
statement (including, without limitation, a Schedule 13E-3 filing, if required
to be filed under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), or information statement (together with any supplement or amendment
thereto, the "Proxy Statement") relating to the Company Stockholders Meeting in
accordance with the Exchange Act and (ii) include in the Proxy Statement the
recommendation of the Special Committee and the Board of Directors of the
Company that stockholders of the Company vote in favor of the approval and
adoption of this Agreement and the transactions contemplated hereby, provided
that the Special Committee or the Board of Directors of the Company may withdraw
or modify its recommendation relating to this Agreement and the Merger pursuant
to the terms of Section 5.3(d) hereof. The Company shall also as soon as
practicable following the execution of this Agreement use its commercially
reasonable efforts (i) to obtain and furnish the information required to be
included by it in the Proxy Statement and, after consultation with Parent,
respond promptly to any comments made by the SEC with respect to the Proxy
Statement and any preliminary version thereof and cause the Proxy Statement to
be mailed to its stockholders at the earliest practicable time following the
execution of this Agreement in accordance with SEC rules and regulations and
(ii) to obtain the necessary approvals by its stockholders of this Agreement and
the transactions contemplated hereby. At the Company Stockholders Meeting,
Parent and Merger Sub will vote all Shares owned by them to approve this
Agreement and the transactions contemplated hereby.

            (c)   Conduct of the Company's Operations. During the period from
the date of this Agreement to the Effective Time, the Company shall conduct its
operations in the ordinary

                                      -27-

course except as expressly contemplated by this Agreement and the transactions
contemplated hereby and shall use all reasonable efforts to maintain and
preserve its business organization and to retain the services of its officers
and key employees and maintain relationships with customers, suppliers, lessees,
licensees and other third parties to the end that its goodwill and ongoing
business shall not be impaired in any material respect. Without limiting the
generality of the foregoing, during the period from the date of this Agreement
to the Effective Time, the Company shall not, except as otherwise expressly
contemplated by this Agreement and the transactions contemplated hereby or as
set forth in Section 5.3(c) to the Company Disclosure Schedule, without the
prior written consent of Parent:

enter into any agreement, understanding or arrangement with respect to the sale,
voting, registration or repurchase of its capital stock;

an accommodation become responsible or liable for the obligations of any other
individual, corporation or other entity;

                  (vii) enter into or modify any employment, severance, stay-put
termination or similar agreements or arrangements (other than at-will employment
arrangements in the ordinary course of business consistent with past practice of
the Company) with, or grant any bonuses, salary increases, severance or
termination pay to, any officer, director, consultant or employee (except for

is given reasonable prior written notice thereof;

                  (x)   enter into, amend or terminate any contract other than

Material Adverse Effect on the Company;

                  (xi)  except as expressly permitted by Section 5.3(d) hereof,

            (d)   No Solicitation. During the term of this Agreement, the
Company shall not, and shall not authorize or permit any of its subsidiaries or
any directors, officers, employees, agents or representatives of the Company or
any of its subsidiaries (including, without limitation, any investment banker,
financial advisor, attorney or accountant retained by the Company or any of its
subsidiaries) to directly or indirectly solicit, initiate, encourage or
facilitate, or furnish or disclose non-public information in furtherance of, any
inquiries or the making of any proposal with respect to any recapitalization,
merger, consolidation or other business combination involving the Company, or
acquisition of any capital stock from the Company (other than upon exercise of
the Company options which are outstanding as of the date hereof) or 15% or more
of the assets of the Company and its subsidiaries, taken as a whole, in a single
transaction or a series of related transactions, or any acquisition by the
Company of any material assets or capital stock of any other person, or any
combination of the foregoing (a "Competing Transaction"), or negotiate or
otherwise engage in discussions with any person (other than Parent or its
directors,

                                      -29-

officers, employees, agents and representatives) with respect to any Competing
Transaction, agree to approve or recommend a Competing Transaction or enter into
any agreement, arrangement or understanding requiring it to abandon, terminate
or fail to consummate the Merger or any other transactions contemplated by this
Agreement; provided, that, at any time prior to the approval of the Merger by
the stockholders of the Company, the Company may furnish information to, and
negotiate or otherwise engage in discussions with, any party who delivers a bona
fide written proposal for a Competing Transaction that was not solicited or
encouraged after the date of this Agreement if and so long as (A) the Special
Committee or the Board of Directors of the Company determines, after
consultation with its outside legal counsel, that failing to take such action
may constitute a breach of the fiduciary duties of the Special Committee or the
Board of Directors of the Company under Applicable Law, (B) the Special
Committee or the Board of Directors of the Company determines that such proposal
is, after consulting with Morgan Stanley (or any other nationally recognized
investment banking firm), if accepted, reasonably likely to be consummated and
is more favorable to the Company's stockholders from a financial point of view
than the transactions contemplated by this Agreement (including any adjustment
to the terms and conditions proposed by Parent in response to such Competing
Transaction) and (C) such proposal is not subject to any financing contingencies
(a "Superior Proposal"); provided, further, that the Company, prior to taking
any such action, notifies Parent not less than two days prior to taking such
action (which notice shall identify the person making the proposal, and describe
the terms thereof) and receives from the person making the proposal an executed
confidentiality agreement in reasonably customary form. The Company shall notify
Parent of any proposal for a Competing Transaction (including the material terms
and conditions thereof and the identity of the person making it) as promptly as
practicable (but in no event more than 24 hours) after its receipt thereof, and
shall thereafter inform Parent on a prompt basis of the status of any discussion
or negotiations with such third party and any material changes to the terms and
conditions of such proposal, and shall promptly give Parent a copy of any
information delivered to such person that has not previously been reviewed by
Parent. The Company will immediately cease all existing activities, discussions
and negotiations with any parties conducted heretofore with respect to any
proposal for a Competing Transaction. Notwithstanding any other provision of
this Section 5.3(d), in the event that prior to the approval of the Merger by
the stockholders of the Company the Special Committee or the Board of Directors
of the Company determines, after consultation with outside legal counsel, that
failure to do so may constitute a breach of the fiduciary duties of the Special
Committee or the Board of Directors of the Company under Applicable Law, the
Special Committee or the Board of Directors of the Company may (subject to this
and the following sentences) withdraw, modify or change, in a manner adverse to
Parent, the Company Board Recommendation and take and disclose to the
stockholders of the Company a position with respect to a Superior Proposal and,
to the extent applicable, comply with Rule 14e-2 and Rule 14d-9 promulgated
under the Exchange Act with respect to a Competing Transaction by disclosing
such withdrawn, modified or changed Company Board Recommendation and
recommendation with respect to the Competing Transaction in connection with a
tender or exchange offer for the Company securities, provided that it gives
Parent two business days prior written notice of its intention to do so. Neither
the Special Committee nor the Board of Directors of the Company shall, in
connection with any such withdrawal, modification or change of the Company Board
Recommendation, take any action to change the approval of the Special Committee
or the Board of Directors of the Company for purposes of causing any state
takeover statute or other state law

                                      -30-

to be applicable to the transactions contemplated hereby, including this
Agreement and the Merger; provided, however, that this sentence shall not
prohibit the Company from withdrawing, modifying or changing its recommendation
or approving or recommending any Superior Proposal under the circumstances and
subject to the conditions set forth in this Section 5.3(d). Notwithstanding any
subsequent determination by the Board of Directors of the Company to change the
Company Board Recommendation, this Agreement shall be submitted to the
stockholders of the Company at the Company Stockholders Meeting for the purpose
of obtaining the approval of the Merger and the transactions contemplated hereby
and nothing contained herein shall be deemed to relieve the Company of such
obligation. From and after the execution of this Agreement, the Company shall
immediately advise Parent in writing of the receipt, directly or indirectly, of
any inquiries, discussions, negotiations, or proposals relating to a Competing
Transaction (including the specific terms thereof and the identity of the other
party or parties involved) and furnish to Parent within three days of such
receipt an accurate description of all material terms (including any changes or
adjustments to such terms as a result of negotiations or otherwise) of any such
written proposal in addition to any information provided to any third party
relating thereto. Notwithstanding any other provision of this Section 5.3(d),
the Company, its directors and its advisors may refer a third party to this
Section 5.3(d).

            (e)   Access. The Company shall permit representatives of Parent to
have full access at all reasonable times and upon reasonable notice to the
Company's premises, properties, books, records, contracts, documents, customers
and suppliers, and shall cause its independent accountants to give Parent access
to such accountants' work papers. Information obtained by Parent pursuant to
this Section 5.3(e) shall be subject to the provisions of the Confidentiality
Agreement, which agreement remains in full force and effect. No investigation
conducted pursuant to this Section 5.3(e) or otherwise shall affect or be deemed
to modify any representation or warranty made in this Agreement. Notwithstanding
the foregoing, the Company shall have no obligation to provide Parent with
information if the Company determines in good faith, upon written advice of its
outside antitrust counsel, that providing information may violate any Applicable
Law.

            (f)   Notification of Certain Matters. The Company shall give prompt
notice to Parent of (i) the occurrence or non-occurrence of any event the
occurrence or non-occurrence of which would likely cause any representation or
warranty by the Company contained in this Agreement to be untrue or inaccurate
at or prior to the Effective Time in any material respect and (ii) any material
failure of the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder; provided, however,
that the delivery of any notice pursuant to this Section 5.3(f) shall not limit
or otherwise affect the remedies available hereunder to Parent.

            (g)   Subsequent Financial Statements. The Company shall consult
with Parent prior to making publicly available its financial results for any
period after the date of this Agreement and prior to filing any Company SEC
Documents after the date of this Agreement, it being understood that Parent
shall have no liability by reason of such consultation.

            (h)   No Redemption of Rights Plan. Other than the amendment
described in Section 5.3(h) of the Company Disclosure Schedule, between the date
of this Agreement and the

                                      -31-

earlier of the Effective Time and the termination of this Agreement, the Company
shall not (a) redeem, amend or waive any provisions of the Rights Plan (other
than such amendments as are necessary to accommodate this Agreement and the
transactions contemplated hereby, but not with respect to any Competing
Transaction) or (b) implement or adopt any so-called "poison pill," stockholder
rights plan or other similar plan.

is capable of being satisfied) so as to cause such Applicable Law not to
prohibit the Merger or the transactions contemplated hereby).

            (d)   There shall not be pending any Action by any Governmental
Authority challenging or seeking to restrain or prohibit the consummation of the
Merger or any of the other transactions contemplated by this Agreement.

            (b)   by either Parent or the Company if there shall be judgment,

covenant or obligation under this Agreement has been the cause of or resulted in
the failure of the Merger to occur on or before such date;

            (d)   by Parent or the Company if at the Company Stockholders
Meeting (including any adjournment or postponement thereof) the Requisite
Company Vote of the stockholders shall not have been obtained to approve the

            (e)   by Parent or the Company if:

                  (x)   there shall have been a material breach by the other of

Agreement pursuant to Section 7.1, this Agreement, except for the provisions of
each of Sections 7.2, 7.3, 8.7 and 8.10, shall become void and have no effect,
without any liability on the part of any party or its directors, officers or
stockholders. Notwithstanding the foregoing, nothing in this Section 7.2 shall
relieve any party to this Agreement of liability for a willful or intentional
breach of any provision of this Agreement and provided, further, however, that
if it shall be judicially determined that termination of this Agreement was
caused by a willful or intentional breach of this Agreement, then, in addition
to other remedies at law or equity for breach of this Agreement, the party so
found to have intentionally breached this Agreement shall indemnify and hold
harmless the other parties for their respective out-of-pocket costs, fees and
expenses of their counsel, accountants, financial advisors and other experts and
advisors as well as fees and expenses incident to negotiation, preparation and

stockholders' meetings and consents ("Costs").

      7.3.  Termination Fee; Expenses.

            (a)   In the event that this Agreement is terminated (i) by Parent
pursuant to Section 7.1(e)(x) due to a material breach by the Company of its
obligations under Section 5.3(d) and, if such breach is of a nature that it may
be cured by the Company, the Company does not cure such breach within 48 hours
after such breach; (ii) pursuant to Section 7.1(f); (iii) pursuant to Section
7.1(g) or (iv) by Parent pursuant to Section 7.1(c) or 7.1(d) in the event (A) a
Competing Transaction shall have been made known to the Company or shall have
been made directly to the stockholders of the Company generally or any person
shall have publicly announced its intention (whether or not conditional) to make
a proposal for a Competing Transaction, (B) the condition set forth in Section
6.1(a) is not satisfied or Parent has terminated this Agreement pursuant to
Section 7.1(c) (but only if a vote to obtain the Requisite Company Vote or the
Company's Stockholder Meeting has not been held), and (C) within 12 months of
such termination, the Company enters into a definitive agreement with respect
to, or consummates, a Competing Transaction, then in any such event, the Company
shall pay to Parent a termination fee equal to $3,000,000 in cash, plus the
reimbursement of any and all Costs incurred by Parent and Merger Sub up to a
maximum of $1,000,000. Except as set forth in Section 7.2, the fee and expense
arrangements contemplated hereby are the sole remedies hereunder (other than
equitable or injunctive relief under Section 8.8) and shall be paid pursuant to
this Section 7.3 regardless of any alleged breach, other than a willful or
intentional breach, by Parent of its obligations hereunder, provided that no
payment made by the Company pursuant to

                                      -35-

this Section 7.3 shall operate or be construed as a waiver by the Company of any
breach of this Agreement by Parent or Purchaser or of any rights of the Company
in respect thereof.

            (b)   Any payment required to be made pursuant to paragraph (a) of
this Section 7.3 shall be made to the Parent not later than two Business Days
after delivery to the Company of notice of demand for payment, or, if earlier,
upon the consummation of a Competing Transaction if such payment is required
pursuant to Section 7.3(a)(iv); provided, that any such payment required
pursuant to Section 7.3(a)(iii) shall be made to Parent in accordance with the
terms of Section 7.1(g) hereof. Any payment required to be made pursuant to
paragraph (a) of this Section 7.3 shall be made to the Parent by wire transfer
of immediately available funds to an account designated by the Parent in the
notice of demand for payment delivered pursuant to this Section 7.3(b).

      7.4.  Amendment. This Agreement may be amended by the parties hereto, by
action taken or authorized by the Special Committee of the Company and by the
respective Boards of Directors of Parent and Merger Sub, at any time before or
after adoption of this Agreement by stockholders of Parent or the Company, but
after any such approval, no amendment shall be made which by law requires
further approval or authorization by the stockholders of Parent or the Company
without such further approval or authorization. Notwithstanding the foregoing,
this Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto.

      7.5.  Extension; Waiver. At any time prior to the Effective Time, Parent
(with respect to the Company) and the Company (with respect to Parent) by action
taken or authorized by their respective Boards of Directors, may, to the extent
legally allowed, (a) extend the time for the performance of any of the
obligations or other acts of such party, (b) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant hereto and (c) waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in a written
instrument signed on behalf of such party.
