                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER, dated as of December 8, 2002 (this
"AGREEMENT") is made and entered into by and among AMY HOLDING COMPANY, a
Delaware corporation ("PARENT"), AMY ACQUISITION CORP., a Delaware corporation
("ACQUISITION"), and AMERIPATH, INC., a Delaware corporation (the "COMPANY").

                                    RECITALS

     WHEREAS, the Board of Directors of each of Parent, Acquisition and the
Company (in the case of the Company acting on the recommendation of a special
committee (the "SPECIAL COMMITTEE") formed for the purpose of representing the
Company in connection with the transactions contemplated hereby) has unanimously
deemed it advisable and in the best interests of their respective stockholders
for Acquisition to merge with and into the Company (the "MERGER") pursuant to
Section 251 of the Delaware General Corporation Law (the "DGCL") upon the terms
and subject to the conditions set forth herein;

     WHEREAS, the Board of Directors of each of Parent, Acquisition and the
Company has unanimously adopted resolutions approving and declaring advisable
this Agreement, the Merger and the transactions contemplated by this Agreement;
and

     WHEREAS, Parent, Acquisition and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties, covenants and agreements herein contained, the parties hereto,
intending to be legally bound, hereby agree as follows:

                                    ARTICLE I

                                   THE MERGER

     1.1     THE MERGER. Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the DGCL, Acquisition shall be
merged with and into the Company at the Effective Time (as hereinafter defined).
At the Effective Time, the separate corporate existence of Acquisition shall
cease and the Company shall continue as the surviving corporation under the name
"Ameripath, Inc." and shall succeed to and assume all of the rights and
obligations of Acquisition in accordance with the DGCL. Acquisition and the
Company are sometimes hereinafter referred to as the "CONSTITUENT CORPORATIONS"
and, as the context requires, the Company is sometimes hereinafter referred to
as the "SURVIVING CORPORATION."

<Page>

     1.2     CLOSING. Unless this Agreement shall have been terminated and
the Merger shall have been abandoned pursuant to Section 7.1, the consummation
of the Merger (the "CLOSING") shall take place as promptly as practical
following the satisfaction and/or waiver (subject to applicable law) of all of
the conditions (other than those conditions which by their nature are to be
satisfied at Closing, but subject to the fulfillment or waiver of those
conditions) set forth in Article VI (and, in any event, not less than two
business days following the satisfaction and/or waiver of all such conditions)
(the "CLOSING DATE"), at the offices of Reboul, MacMurray, Hewitt & Maynard, 45
Rockefeller Plaza, New York, New York 10111, unless another date, time or place
is agreed to in writing by the parties hereto.

     1.3     EFFECTIVE TIME OF THE MERGER. At Closing, the parties hereto
shall cause the Merger to be consummated by filing a certificate of merger (the
"CERTIFICATE OF MERGER") with the Secretary of State of the State of Delaware as
provided in the DGCL. The Merger shall become effective upon such filing or at
such time thereafter as Parent, Acquisition and the Company shall agree and
specify in the Certificate of Merger (the "EFFECTIVE TIME").

     1.4     EFFECTS OF THE MERGER.

             (a)  The Merger shall have the effects set forth in this
Agreement, the Certificate of Merger and the applicable provisions of the DGCL.

             (b)  The directors of Acquisition and the officers of the
Company immediately prior to the Effective Time shall, from and after the
Effective Time, be the initial directors and officers of the Surviving
Corporation until their successors have been duly elected or appointed and
qualified, or until their earlier death, resignation or removal in accordance
with the Surviving Corporation's Certificate of Incorporation and Bylaws.

             (c)  Subject to Section 5.5(a), the Certificate of
Incorporation of Acquisition as in effect immediately prior to the Effective
Time shall be the Certificate of Incorporation of the Surviving Corporation
following the Merger until thereafter amended in accordance with its terms and
the DGCL.

             (d)  The Bylaws of Acquisition as in effect immediately prior
to the Effective Time shall be the Bylaws of the Surviving Corporation following
the Merger until thereafter amended in accordance with the DGCL, the Certificate
of Incorporation of the Surviving Corporation and the Bylaws of the Surviving
Corporation.

                                   ARTICLE II

               EFFECT OF THE MERGER ON THE OUTSTANDING SECURITIES
              OF THE CONSTITUENT CORPORATIONS; EXCHANGE PROCEDURES

     2.1     EFFECT ON CAPITAL STOCK. As of the Effective Time, by virtue
of the Merger and without any action on the part of the holder of any shares of
common stock, par value $.01 per share, of the Company (the "COMPANY COMMON
STOCK") or Parent:

             (a)  COMMON STOCK OF ACQUISITION. Each share of common stock,
par value $.01 per share, of Acquisition (the "ACQUISITION COMMON STOCK") issued
and outstanding

                                        2
<Page>

immediately prior to the Effective Time shall be converted into and become one
fully paid and nonassessable share of common stock, par value $.01 per share, of
the Surviving Corporation.

             (b)  CANCELLATION OF TREASURY STOCK AND COMPANY COMMON STOCK
OWNED_BY PARENT OR ACQUISITION. Each share of Company Common Stock that is
owned by Parent or Acquisition or any affiliate of Parent or Acquisition or held
in the treasury of the Company, in each case together with the Rights (as
hereinafter defined) associated therewith (collectively, the "EXCLUDED SHARES"),
shall automatically be canceled and retired and shall cease to exist, and no
cash or other consideration shall be delivered or deliverable in exchange
therefor.

             (c)  CONVERSION OF COMPANY COMMON STOCK. Each share of Company
Common Stock issued and outstanding immediately prior to the Effective Time
other than Excluded Shares and Dissenting Shares (as hereinafter defined),
together with the Rights associated therewith, shall be converted into the right
to receive in cash from the Surviving Corporation following the Merger an amount
equal to $21.25 (the "MERGER CONSIDERATION").

             (d)  DISSENTING SHARES. Notwithstanding anything in this
Agreement to the contrary, shares of Company Common Stock (and associated
Rights) that are issued and outstanding immediately prior to the Effective Time
and that are held by a holder who has validly demanded payment of the fair value
for such holder's shares as determined in accordance with Section 262 of the
DGCL ("DISSENTING SHARES") shall not be converted into or be exchangeable for
the right to receive the Merger Consideration unless and until such holder shall
have failed to perfect or shall have effectively withdrawn or lost such holder's
appraisal right under the DGCL (but instead shall be converted into the right to
receive payment from the Surviving Corporation with respect to such Dissenting
Shares in accordance with the DGCL). If any such holder shall have failed to
perfect or shall have effectively withdrawn or lost such right, each share of
such holder (and each associated Right) shall be treated as a share of Company
Common Stock (and associated Right) that had been converted as of the Effective
Time into the right to receive the Merger Consideration in accordance with
Section 2.1(c). The Company shall give prompt notice to Parent of any demands,
attempted withdrawals of such demands and any other instruments served pursuant
to the DGCL received by the Company for appraisal of shares of Company Common
Stock, and Parent shall have the right to participate in and direct all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of Parent, voluntarily make any
payment with respect to, settle, offer to settle, or approve any withdrawal of
any such demands.

             (e)  CANCELLATION AND RETIREMENT OF COMPANY COMMON STOCK. As
of the Effective Time, all shares of Company Common Stock (other than Excluded
Shares and Dissenting Shares) and all associated Rights that are issued and
outstanding immediately prior to the Effective Time shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate representing any shares of Company
Common Stock and associated Rights being converted into the right to receive the
Merger Consideration pursuant to Section 2.1(c) (the "CERTIFICATES") shall
cease to have any rights with respect to such shares of Company Common Stock or
associated Rights, except the right to receive a cash amount equal to the Merger
Consideration per share multiplied by the number of shares so represented, to be
paid in consideration therefor upon surrender of such Certificate in accordance
with Section 2.2(b).

                                        3
<Page>

             (f)  CERTAIN ADJUSTMENTS. In the event that prior to the
Effective Time, solely as a result of a reclassification, stock split (including
a reverse stock split), combination or exchange of shares, stock dividend or
stock distribution which in any such event is made on a pro rata basis to all
holders, there is a change in the number of shares of Company Common Stock
outstanding or issuable upon the conversion, exchange or exercise of securities
or rights convertible or exchangeable or exercisable for shares of Company
Common Stock, then the Merger Consideration shall be equitably adjusted to
eliminate the effects of such event.

     2.2     EXCHANGE OF CERTIFICATES.

             (a)  PAYING AGENT. Prior to the Effective Time, Parent shall
appoint a bank or trust company reasonably acceptable to the Company to act as
paying agent (the "PAYING AGENT") for the payment of the Merger Consideration
upon surrender of the Certificates. At the Effective Time, the Surviving
Corporation shall deposit (and Parent shall cause to be deposited) with the
Paying Agent, for the benefit of the holders of such Certificates, for use in
the payment of the Merger Consideration in accordance with this Article II, the
aggregate Merger Consideration (such cash consideration being hereinafter
referred to as the "MERGER FUND"). The Paying Agent shall, pursuant to
irrevocable instructions of the Surviving Corporation given at the Closing, make
payments of the Merger Consideration out of the Merger Fund. The Merger Fund
shall not be used for any other purpose.

             (b)  EXCHANGE PROCEDURES. Promptly after the Effective Time,
the Surviving Corporation shall cause the Paying Agent to mail or deliver to
each Person (as hereinafter defined) who was, at the Effective Time, a holder of
record of Company Common Stock and whose shares are being converted into the
Merger Consideration pursuant to Section 2.1(c) a letter of transmittal (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 otherwise be in a form and have such other provisions as the
Surviving Corporation may reasonably specify) containing instructions for use by
holders of Company Common Stock to effect the exchange of their shares of
Company Common Stock for the Merger Consideration as provided herein. As soon as
reasonably practicable after the Effective Time, each holder of an outstanding
Certificate or Certificates shall, upon surrender to the Paying Agent of such
letter of transmittal duly executed and completed in accordance with the
instructions thereto (together with such other documents as the Paying Agent may
reasonably request) and such Certificate or Certificates (or, if such shares are
held in book-entry or other uncertificated form, upon the entry through a
book-entry transfer agent of the surrender of such shares of Company Common
Stock on a book-entry account statement (it being understood that any references
herein to "Certificates" shall be deemed to include references to book-entry
account statements relating to the ownership of shares of Company Common
Stock)), be entitled to an amount of cash (payable by check) equal to the Merger
Consideration per share multiplied by the number of shares of Company Common
Stock represented by such Certificate or Certificates. The Paying Agent shall
accept such Certificates upon compliance with such reasonable terms and
conditions as the Paying Agent may impose to effect an orderly exchange thereof
in accordance with normal exchange practices. After the Effective Time, there
shall be no further transfer on the records of the Company or its transfer agent
of Certificates, and if such Certificates are presented to the Company for
transfer, they shall be canceled against delivery of the Merger Consideration.
If cash is to be remitted to a Person other than the Person in whose name the
Certificate

                                        4
<Page>

surrendered for exchange is registered, it shall be a condition of such exchange
that the Certificate so surrendered shall be properly endorsed, with signature
guaranteed, or otherwise in proper form for transfer and that the Person
requesting such exchange shall pay to the Paying Agent any transfer or other
taxes required by reason of the payment of the Merger Consideration to a Person
other than the registered holder of the Certificate so surrendered, or shall
establish to the satisfaction of the Paying Agent that such tax either has been
paid or is not applicable. Until surrendered as contemplated by this
Section 2.2(b), at any time after the Effective Time, each Certificate shall be
deemed to represent only the right to receive the Merger Consideration upon such
surrender as contemplated by Section 2.1. No interest will be paid or will
accrue on any cash payable as Merger Consideration.

             (c)  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK
EXCHANGED FOR CASH. All cash paid upon the surrender for exchange of
Certificates representing shares of Company Common Stock in accordance with the
terms of this Article II shall be deemed to have been paid in full satisfaction
of all rights pertaining to the shares of Company Common Stock exchanged for
cash theretofore represented by such Certificates, and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock which were issued and
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be cancelled and exchanged as provided in this Article II.

             (d)  TERMINATION OF MERGER FUND. Any portion of the Merger
Fund which remains undistributed to the holders of Certificates for 270 days
after the Effective Time shall be delivered to the Surviving Corporation, and
any holders of Certificates who have not theretofore complied with this Article
II shall thereafter look only to the Surviving Corporation and only as general
creditors thereof for payment of the Merger Consideration, subject to escheat
and abandoned property and similar Laws. As used herein, "LAWS" means any
statute, law, ordinance, rule, regulation, Nasdaq or other stock exchange rule
or listing requirement, permit or authorization applicable to a Person (as
hereinafter defined) or such Person's Subsidiaries or their respective
properties or assets.

             (e)  NO LIABILITY. None of Parent, the Surviving Corporation
or the Paying Agent shall be liable to any Person in respect of any cash from
the Merger fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar Law. If any Certificate shall not have
been surrendered prior to seven years after the Effective Time (or immediately
prior to such earlier date on which any cash in respect of such Certificate
would otherwise escheat to or become the property of any Governmental Entity (as
hereinafter defined)), any such cash in respect of such Certificate shall, to
the extent permitted by applicable Law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any Person previously
entitled thereto.

             (f)  INVESTMENT OF MERGER FUND. The Paying Agent shall invest
any cash in the Merger Fund solely in Cash Equivalents (as defined below) as
directed by the Surviving Corporation. Any interest and other income resulting
from such investments shall be paid to the Surviving Corporation. As used
herein, "CASH EQUIVALENTS" means, as of any date of determination, (i)
marketable securities (a) issued or directly and unconditionally guaranteed as
to interest and principal by the United States government or (b) issued by any
agency of the

                                        5
<Page>

United States the obligations of which are backed by the full faith and credit
of the United States, in each case maturing within six months after such date;
(ii) marketable direct obligations issued by any state of the United States of
America or any political subdivision of any such state or any public
instrumentality thereof, in each case maturing within six months after such date
and having, at the time of the acquisition thereof, the highest rating
obtainable from either Standard & Poor's Ratings Group ("S&P") or Moody's
Investors Service, Inc. ("MOODY'S"); (iii) commercial paper maturing no more
than six months from the date of creation thereof and having, at the time of the
acquisition thereof, a rating of at least A-l from S&P or at least P-l from
Moody's; (iv) certificates of deposit maturing within six months after such date
and issued or accepted by any commercial bank organized under the laws of the
United States of America or any state thereof or the District of Columbia that
(a) is at least "adequately capitalized" (as defined in the regulations of its
primary Federal banking regulator) and (b) has Tier 1 capital (as defined in
such regulations) of not less than $100,000,000; and (v) shares of any money
market mutual fund that (a) has at least 95% of its assets invested continuously
in the types of investments referred to in clauses (i) and (ii) above, (b) has
net assets of not less than $500,000,000, and (c) has the highest rating
obtainable from either S&P or Moody's.

             (g)  WITHHOLDING RIGHTS. The Surviving Corporation or the
Paying Agent shall be entitled to deduct and withhold from the consideration
otherwise payable pursuant to this Agreement to such holder such amounts as the
Surviving Corporation 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, and the rules and regulations promulgated thereunder (the
"CODE"), or any provision of state, local or foreign tax Law. To the extent that
amounts are so deducted and withheld by the Surviving Corporation 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 the Surviving
Corporation or the Paying Agent.

             (h)  LOST CERTIFICATES. If any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such Person of a bond in
such reasonable amount as the Surviving Corporation may require as indemnity
against any claim that may be made against it with respect to such Certificate,
the Paying Agent will issue in exchange for such lost, stolen or destroyed
Certificate the Merger Consideration payable pursuant to this Agreement.

     2.3     EFFECT OF THE MERGER ON OPTIONS AND WARRANTS. (a) Each of the
Company's stock option plans, programs and arrangements (the "STOCK PLANS") and
outstanding options to acquire shares of Company Common Stock (the "COMPANY
STOCK OPTIONS"), including information concerning the Stock Plan under which
such options were issued, the holders thereof, the number of shares subject
thereto, the exercise prices thereof, the dates of scheduled vesting thereof and
the terms thereof that require acceleration of such vesting by virtue of the
Merger, are set forth on SCHEDULE 2.3(a).

             (b)  Subject to Section 2.3(e) below, at the Effective Time of
the Merger (and the Board of Directors of the Company or any committee
administering the Stock Plans shall take all actions necessary so that), all
outstanding Company Stock Options heretofore granted

                                        6
<Page>

under any Stock Plan become fully vested and exercisable at the Effective Time
and shall be cancelled in exchange for the right to receive a cash payment by
the Surviving Corporation at the Effective Time of an amount equal to (i) the
excess, if any, of (x) the per share Merger Consideration over (y) the exercise
price per share of Common Stock subject to such Company Stock Option, multiplied
by (ii) the number of shares of Common Stock for which such Company Stock Option
shall not theretofore have been exercised.

             (c)  The Stock Plans shall terminate as of the Effective Time
of the Merger, and the provisions in any other benefit plan providing for the
issuance, transfer or grant of any capital stock of the Company or any interest
in respect of any capital stock of the Company shall be deleted as of the
Effective Time of the Merger, and the Company shall take such actions to ensure
that following the Effective Time of the Merger no holder of a Company Stock
Option or any participant in any Stock Plan or other benefit plan shall have any
right thereunder to acquire any capital stock or any interest in respect of any
capital stock of the Surviving Corporation.

             (d)  All outstanding warrants to acquire shares of Company
Common Stock (the "COMPANY WARRANTS"), including information concerning the
holders thereof, the number of shares subject thereto and the exercise prices
thereof, are set forth on SCHEDULE 2.3(d). As soon as practicable following the
date of this Agreement, the Company shall use its reasonable best efforts to
take such actions (which shall include attempting to obtain all required
consents of holders of Company Warrants) as may be necessary to effectuate the
cancellation at the Effective Time of each Company Warrant in exchange for a
cash payment equal to the product of (1) the excess, if any, of the Merger
Consideration per share over the exercise price per share of such Company
Warrant and (2) the number of shares of Company Common Stock subject to such
Company Warrant.

             (e)  The Surviving Corporation shall be entitled to deduct and
withhold from the amounts otherwise payable pursuant to this Section 2.3 to any
holder of Company Stock Options or Company Warrants such amounts as the
Surviving Corporation 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 deducted and withheld by the
Surviving Corporation, such withheld amounts shall be treated for all purposes
of this Agreement as having been paid to the holder of the Company Stock Options
or Company Warrants in respect of which such deduction and withholding was made

     corporation or (ii) any equity or other participating interest in the
     revenues or profits of any corporation, partnership, limited liability
     company, joint venture or other entity, association or business enterprise
     and the Company is not subject to any obligation to make any investment (in
     the form of a loan, capital contribution or otherwise) in any corporation,
     partnership, limited liability company, joint venture or other entity,
     association or business enterprise.

to, individually or in the aggregate, have a Company Material Adverse Effect.
The conduct by the Company, its Subsidiaries and the Company Managed Practices
of their respective businesses has been and is in compliance with all applicable

     Company, any of its Subsidiaries or any Company Managed Practice in any
     Government Program or Private Program. No event has occurred which, with or

             (h)  ABSENCE OF LITIGATION AND ORDERS. There is no claim, action,

forthwith become void and there shall be no liability or further obligation
hereunder on the part of any party hereto or their

<Page>

respective affiliates, officers, directors or stockholders, except that the last

             (b)  Except for the termination rights provided in Section 7.1 and
except as otherwise provided in Section 8.2, the Company acknowledges and agrees
that its remedy for any claim asserted by the Company against Parent or
Acquisition, including, without limitation, any claim that arises out of or
relates in any way to the negotiation, entry into, performance, or the terms of
this Agreement or the transactions contemplated hereby or the breach or claimed
breach thereof shall be limited to the remedy as agreed to in the Contingency
Letter Agreement among WCAS, the Company and Parent dated of even date herewith
and such remedy shall only be available if this Agreement shall have been

claimed breaches by Parent and/or Acquisition giving rise to such termination

measure of damages shall apply regardless of the theory upon which recovery
hereunder is sought.

agreements that contemplate performance after the Effective Time (which
covenants and agreements shall survive in accordance with their terms).

     8.2     SPECIFIC PERFORMANCE. The parties hereto acknowledge and agree that
any breach or threatened breach of the terms of this Agreement would give rise
to irreparable harm for which money damages would not be an adequate remedy and
accordingly the parties agree that, in addition to any other remedies, each

specific performance without the necessity of proving the inadequacy of money
damages as a remedy.

construed to refer to this Agreement as

                                       53
<Page>

a whole and not to any particular provision of this Agreement, and the words
"Article" and "Section" are references to the articles and sections of this
Agreement unless otherwise specified. Whenever the words "include", "includes"
or "including" are used in this Agreement they shall be deemed to be followed by
the words "without limitation". Unless otherwise provided herein, each
accounting term used in this Agreement has the meaning given to it in accordance
with GAAP. As used in this Agreement, the term "AFFILIATE" shall have the
meaning set forth in Rule 12b-2 promulgated under the Exchange Act. The
definitions contained in this Agreement are applicable to the singular as well
as the plural forms of such terms and to the masculine as well as to the
feminine and neuter genders of such terms. Any agreement or statute referred to
herein means such agreement or statute as from time to time amended, qualified
or supplemented, including, in the case of statutes, by succession of comparable
successor statutes. References to the Securities Act and to the Exchange Act are
also references to the rules and regulations of the SEC promulgated thereunder.
References to a Person are also to its successors and permitted assigns. The
table of contents and headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement. The parties hereto have participated jointly in the negotiation
and drafting of this Agreement. In the event an ambiguity or question of intent
or interpretation arises, this Agreement shall be construed as if drafted
jointly by the parties and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any provisions
of this Agreement. As used in this Agreement, the phrase "to the knowledge of
the Company" shall mean to the actual knowledge of the individuals listed on
Schedule 8.4, after reasonable inquiry.

     8.5     COUNTERPARTS. This Agreement may be executed in two or more
counterparts (and may be delivered by facsimile), each of" which shall be deemed
an original, but all of which together shall constitute one and the same
instrument.

     8.6     ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES. This Agreement,
including the schedules hereto, together with the Confidentiality Agreement,
constitutes the entire agreement of the parties hereto with respect to the
subject matter hereof and supersedes all prior agreements and understandings,
both written and oral, between the parties hereto with respect to the subject
matter hereof (other than the Confidentiality Agreement which shall survive the
execution and delivery of this Agreement). This Agreement shall be binding upon
and inure to the benefit of each party hereto and to their respective successors
and permitted assigns, and, except as provided in Section 5.5 and Section 5.10,
nothing in this Agreement, express or implied, is intended to or shall confer
upon any other Person any other right, benefit or remedy of any nature
whatsoever under or by reason of this Agreement.

     8.7     AMENDMENT. This Agreement may be amended, modified or supplemented,
only by written agreement of Parent, Acquisition and the Company at any time
prior to the Effective Time with respect to any of the terms contained herein;
PROVIDED, that, after Company Stockholder Approval is obtained, no term or
condition contained in this Agreement shall be amended or modified in any manner
that by Law requires further approval by the stockholders of the Company without
so obtaining such further stockholder approval.

     8.8     WAIVER. At any time prior to the Effective Time, the parties
hereto, 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 required hereby, (b)

                                       54
<Page>

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 by such party. No failure or delay by any party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof nor shall any single or partial exercise thereof preclude any Other or
further exercise thereof or the exercise of any other right, power or privilege.

     8.9     GOVERNING LAW. This Agreement, and all claims arising hereunder,
shall be governed and construed and enforced in accordance with the Laws of the
State of Delaware, without giving effect to the principles of conflicts of Law
thereof.

     8.10    SUBMISSION TO JURISDICTION. Each of the parties hereto irrevocably
and unconditionally submits, for itself and its property, to the exclusive
jurisdiction of the Delaware Court of Chancery or, in the event (but only in the
event) such court does not have subject matter jurisdiction, any other court of
the state of Delaware or the United States District Court for the District of
Delaware, in any action or proceeding arising out of or relating to this
Agreement. Each of the parties hereto agrees that, subject to rights with
respect to post-trial motions and rights of appeal or other avenues of review, a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by Law. Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or relating to this Agreement in the
Delaware Court of Chancery or any other state court of the State of Delaware or
the United States District Court for the District of Delaware. Each of the
parties hereto irrevocably and unconditionally waives, to the fullest extent it
may legally and effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

     8.11    ASSIGNMENT. No party hereto shall assign this Agreement or any of
its rights, interests or obligations hereunder (whether by operation of Law or
otherwise) without the prior written consent of the other parties hereto. Any
assignment in violation of the foregoing shall be null and void.

     8.12    SEVERABILITY. If any term or other provision of this Agreement is
finally determined by a court of competent jurisdiction, by final judgment no
longer subject to review, to be invalid, illegal or incapable of being enforced,
all other terms and provisions of this Agreement shall nevertheless remain in
full force and effect so long as neither the economic nor legal substance of the
transactions contemplated herein is affected in any manner materially adverse to
any party hereto. Upon such determination that any term or other provision is
invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in a mutually acceptable manner.
