or destroyed, and the receipt by Buyer of an appropriate and customary
indemnity, Buyer will issue, in exchange for such lost, stolen or destroyed
certificate, one or more certificates representing Buyer Shares and the
fractional share payment, if any, deliverable with respect thereof, as
determined in accordance with this Section 2.4.

     (g) Fractional Shares.  In lieu of the issuance of fractional Buyer Shares

number of Buyer Shares (collectively, the "Escrow Shares") equal to the product,
rounded to the nearest whole share, of (X) the number of Buyer Shares such
holder would have otherwise received pursuant to Section 2.4(e) multiplied by
(Y) the Escrow Ratio. The "Escrow Ratio" shall be the quotient obtained by
dividing (X) One Hundred Twenty-Seven Thousand (127,000) by (Y) the arithmetic
difference between Seven Million Seven Hundred Thousand (7,700,000) and the
aggregate number of the Preferred Exchange Shares. At the Closing, Buyer shall
deposit with the Escrow Agent one or more stock certificates representing the
Escrow Shares.

     (i) Restricted Shares.  To the extent that any Seller Share is subject to
restrictions on transfer and/or forfeiture provisions pursuant to any agreement
between the holder and Seller, the Buyer Shares delivered in exchange therefor
shall be subject to the same restrictions if in the reasonable opinion of
Buyer's legal and accounting advisors the continuation of such restrictions are
necessary in order for the Merger to qualify for "pooling of interests"
accounting treatment under Accounting Principles Board Opinion No. 16.

     (j) Dissenting Shares.  Notwithstanding anything in this Agreement to the
contrary, Dissenting Shares shall not be converted into the right to receive, or
be exchangeable for, the Merger consideration provided for in Section 2.4(e),
but, instead, each holder of Dissenting Shares shall be entitled to payment by

     2.5  Buyer Warrants.  At the Closing, Buyer shall deliver the Buyer
Warrants in exchange for the CMP Warrant.

          (a) Warrant Shares.  As used in this Agreement, the term "Warrant
     Shares" means that number, rounded up to the nearest whole integer, which
     is equal to the product of (X) the Seller Common Ratio applicable to the
     CMP Warrant, treating CMP as a holder of Seller Common Shares, multiplied
     by (Y) Seven Million Seven Hundred Thousand (7,700,000) minus the aggregate
     number of the Preferred Exchange Shares.

          (b) Escrow Warrant.  Buyer shall deliver at the Closing to the Escrow
     Agent a warrant (the "Escrow Warrant") entitling CMP or any successor
     holder thereof to purchase Buyer Shares. The Escrow Warrant shall be
     identical in all material respects to the CMP Warrant, except that (i) the
     number of Buyer Shares purchasable immediately after the Closing upon the
     full exercise of the Escrow Warrant shall be that number, rounded to the
     nearest whole share, which is equal to the product of (X) the total number
     of Warrant Shares multiplied by (Y) the Escrow Ratio, and (ii) the exercise
     price per Buyer Share of the Escrow Warrant shall be that price, rounded to
     the nearest tenth of a cent ($.001), which is equal to the quotient of (X)
     $1,500 divided by (Y) the total number of Warrant Shares.

          (c) Closing Warrant.  Buyer shall deliver at the Closing to CVC, as
     agent for CMP, a warrant (the "Closing Warrant") entitling CMP or any
     successor holder thereof to purchase Buyer Shares. The exercise price per
     Buyer Share of the Closing Warrant shall be the same as the exercise price
     per Buyer Share of the Escrow Warrant, and the Closing Warrant shall
     otherwise be identical in all material respects to the Escrow Warrant,
     except that the number of Buyer Shares purchasable immediately after the
     Closing upon the full exercise of the Closing Warrant shall be equal to the
     arithmetic difference between (X) the total number of Warrant Shares and
     (Y) the number of Buyer Shares purchasable immediately after the Closing
     upon the full exercise of the Escrow Warrant.

          (d) If the CMP Warrant is exercised in part prior to the Closing,
     there will be an appropriate adjustment to the number of Warrant Shares and
     the exercise price of the Buyer Warrants. If the CMP Warrant is exercised
     in full prior to the Closing, none of the Buyer Warrants will be issued in
     the Merger.

     2.6  Anti-Dilution.  In the event that, subsequent to the date of this
Agreement but prior to the Effective Time, the outstanding shares of Buyer
Common Stock shall have been increased, decreased, changed into or exchanged for
a different number of shares or securities through a split, reverse stock split,
or other like changes in Buyer's capitalization, other than pursuant to this
Agreement, as the case may be (a "Recapitalization"), then an appropriate and
proportionate adjustment shall be made to the number of Buyer Shares so that
each Seller Stockholder shall receive under Section 2.4, or upon exercise of the
Buyer Warrants, the number of Buyer Shares (except for fractional shares) that
such stockholder would have held immediately after the Recapitalization if the
Merger had occurred immediately prior to the Recapitalization or the record date
therefor, as applicable. For purposes of this Section 2.6 and by way of
illustration and not limitation, a "Recapitalization" will in no event include
the (i) issuance of shares or securities by Buyer pursuant to any existing or
hereafter established or granted stock option or equity award or other
compensation plan or arrangement to, or for the benefit of, one or more
employees, officers, directors or contractors of Buyer or any of its
Subsidiaries or (ii) in connection with Buyer acquiring directly or indirectly
the stock or assets of any other Person.

     Seller represents and warrants to Buyer and the Merger Sub that the
statements contained in this Section 3 are correct and complete as of the date

be repeated on the Closing Date.

     3.1  Organization, Qualification, and Corporate Power.  Each of Seller and
its Subsidiaries is a corporation duly organized, validly existing, and in good
standing under the laws of its jurisdiction of incorporation. Each of Seller and
its Subsidiaries is duly authorized to conduct business and is in good standing
under the laws of each jurisdiction where the absence of such qualification
would have a Material Adverse Effect on Seller. Schedule 3.1 lists each of the
jurisdictions in which Seller or any of its Subsidiaries possess any foreign
qualification or license and lists such license held in such jurisdiction. Each
of Seller and its Subsidiaries has the corporate power and authority necessary
to carry on the businesses in which each is engaged and to own, lease and use

delivered to Buyer a true and complete copy of its certificate of incorporation

authority to execute and deliver this Agreement and to perform its obligations
hereunder. This Agreement has been duly authorized by the board of directors of
Seller, has been duly executed and delivered on behalf of Seller, and
constitutes the valid and legally binding obligation of Seller, enforceable in
accordance with its terms and conditions. The only vote of Seller Stockholders
necessary to approve this Agreement or the consummation of the Merger is the
affirmative vote of the holders of a majority of the outstanding shares of Class
A Common Stock entitled to vote thereon approving this Agreement, and the Seller
Board of Directors has directed the officers of Seller to submit this Agreement
to the holders of Seller Voting Shares for Seller Stockholder Approval. No other
corporate proceedings on the part of Seller not heretofore taken are necessary
to approve this Agreement or to consummate the Merger.

     3.3  Noncontravention.  Neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby, will (i)
violate any constitution, statute, regulation, rule, injunction, judgment,
order, decree, ruling, charge, or other restriction of any government,
governmental agency, or court to which Seller or any of its Subsidiaries is
subject or any provision of the certificate of incorporation or charter or
bylaws of Seller or any of its Subsidiaries or (ii) conflict with, result in a
breach of, constitute a default (or any event which, with notice or lapse of
time, or both, would constitute a default) under, result in the acceleration of,
create in any party a put right or repurchase obligation or the right to
accelerate, terminate, modify or cancel, create any Security Interest or require
any notice, under any material Contract to which Seller or any of its
Subsidiaries is a party or by which any is bound or to which any of its assets
is subject, including, without limitation, the Grace Agreement, except for any
such matters identified on Schedule 3.3. Other than in connection with the
provisions of the HSRA and the DGCL, none of Seller or any of its Subsidiaries
needs to give any notice to, make any filing with, or obtain any authorization,
consent, or approval of any government or governmental agency or other Person in
order to consummate the Merger.

     3.4  Capitalization of Seller and its Subsidiaries.  Seller's authorized
capital stock consists of 2,019,076 authorized shares of capital stock, which
shares are fully described on and held of record by the persons and in the

                                      A-16
<PAGE>   17

common stock or preferred stock issued or reserved for issuance, or (ii) any
Contract of any character to which Seller or any of its Subsidiaries or, to
Seller's knowledge, any Affiliate of Seller is a party or subject relating to
its capital stock or otherwise representing a right to receive any of its
capital stock, nor are there any pending or, to Seller's knowledge, threatened
claims or demands for, a direct or indirect equity interest in Seller or any
Subsidiary, including, without limitation, any option, warrant, right or call or
any stock appreciation, phantom stock, profit participation or similar rights.
All of the issued and outstanding shares of capital stock of Seller have been
duly authorized and validly issued, and are fully paid and are nonassessable.
Except as set forth on Schedule 3.4, there are no voting trusts, proxies or any
other agreements or understandings with respect to the voting of the capital
stock of Seller or any of its Subsidiaries.

     3.5  Subsidiaries.  All Subsidiaries of Seller are listed on Schedule 3.5.
Except as otherwise disclosed in Schedule 3.5, neither Seller nor any Subsidiary
owns any shares of stock of any corporation or any equity interest in a
partnership, joint venture or other business entity, and neither Seller nor any
of its Subsidiaries controls any other corporation, partnership, joint venture
or other business entity by means of ownership, management contract or
otherwise. Except for nominal qualifying shares held by residents of certain
foreign jurisdictions but which are beneficially owned by Seller or its
Subsidiaries, all of the outstanding capital stock of, or other ownership
interests in, each Subsidiary of Seller is owned beneficially and of record by
Seller, directly or indirectly, is validly issued, fully paid and nonassessable

Security Interests, except as provided under the Securities Act or state

unaudited consolidated balance sheet and statements of income, cash-flow and
shareholders' equity as of and for the three-month and twelve-month periods

and present fairly the financial position of the respective entities as at the

of the Securities Act, the Securities Act regulations, including, without
limitation, Regulation S-X, and the Exchange Act, except as may be described on
Schedule 3.6. Except as set forth in the Financial Statements or described on
Schedule 3.6, neither Seller nor any of its Subsidiaries has (i) any Loss
Contingency which is not required by GAAP to be accrued and which if resolved
adversely to Seller or any of its Subsidiaries could have an Material Adverse
Effect on Seller or (ii) any other Liability material to Seller and its
Subsidiaries on a consolidated basis that is not required by GAAP to be accrued.

judgments, decrees, lawsuits, actions, proceedings, claims, complaints,
injunctions, orders or investigations by or before any Governmental Entity
pending or, to Seller's knowledge, threatened against Seller or its Subsidiaries
(i) which could be reasonably expected to have a Material Adverse Effect on
Seller if adversely determined, or (ii) seeking to enjoin any aspect of the
Merger. To Seller's knowledge, there are no existing facts or circumstances
which give any reason to believe that any such action, suit, proceeding, hearing
or investigation may be brought or threatened against Seller or any of its
Subsidiaries.

     3.8  Absence of Certain Developments.  Except as disclosed in Schedule 3.8,
since December 31, 1997 no event has occurred which has had or reasonably could

Health, and Safety Requirements, in all material respects, (ii) without limiting
the generality of the foregoing, Seller and each of its Subsidiaries have
obtained and complied with, and are in compliance with, in all material
respects, all permits, licenses and other authorizations that are required
pursuant to the Environmental, Health, and Safety Requirements for the
occupation of their facilities and the operation of their business, (iii)
neither Seller nor any of its Subsidiaries has received any notice regarding any
actual or alleged material violation of Environmental, Health, and Safety
Requirements, or any material Liability or Loss Contingency arising under the
Environmental, Health, and Safety Requirements (including any investigatory,
remedial or corrective obligations) (iv) neither Seller nor any of its
Subsidiaries has treated, stored, disposed of, arranged for or permitted the
disposal of, transported, handled, or released any Hazardous Material or owned
or operated any property or facility (and no such property or facility is
contaminated by any Hazardous Material) in a manner that has given or reasonably
could be expected to give rise to any material Liability, including Liability
for response costs, corrective action costs, personal injury, property damage,
natural resources damages or attorney fees, pursuant to the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, the
Solid Waste Disposal Act, as amended, or any other Environmental, Health, and
Safety Requirements, and (vi) neither Seller nor any of its Subsidiaries has,
either expressly or by operation of law, assumed, undertaken or otherwise become
subject to any material Liability of any other Person relating to Environmental,
Health, and Safety Requirements.

     (b) There are no environmental investigations, studies, reviews, audits,
tests or other analyses of environmental conditions conducted by or which are in
the possession, custody or control of Seller or any of its Subsidiaries relating
to the operation of Seller's business or any facility owned, leased or operated
by Seller or any of its Subsidiaries, except as listed on Schedule 3.10(b),
copies of which have been made available to Buyer, except for those identified
as privileged on Schedule 3.10(b).

     3.11  Employee Benefit Plans.

     (a) Schedule 3.11(a) lists all bonus, compensation, deferred compensation,
pension, retirement, profit-sharing, thrift, savings, employee stock ownership,
stock bonus, stock purchase, restricted stock and stock option plans, all
employment or severance contracts, health and medical plans, life insurance and
disability plans, vacation and other employee benefit plans, policies,
contracts, agreements or arrangements, which at any time during the 24 month
period ending on the Closing Date cover (or covered) any employee(s) or former
employee(s) of Seller, any of its Subsidiaries, any ERISA Affiliate and/or any
such employees' beneficiaries or with respect to which Seller or any of its
Subsidiaries or any ERISA Affiliate had, or has, any actual or potential
Liability, including, but not limited to, all "employee benefit plans" within
the meaning of Section 3(3) of ERISA (the "Benefit Plans"); provided, however,
that with reference to "employee benefit plans" within the meaning of Section
3(3) of ERISA, the 24 month period referenced above shall be lengthened to a 60
month period. Except, as set forth on Schedule 3.11(a), no Benefit Plan is or
was established, maintained or contributed to including any Benefit Plan to
which there is (or was) an obligation to contribute to pursuant to an agreement
with an employee organization (within the meaning of Section 3(4) of ERISA).
Except as set forth on Schedule 3.11(a), no Benefit Plan has terms requiring
assumption by Buyer or the

                                      A-21
<PAGE>   22

Merger Sub. No Benefit Plan is a multiemployer plan (as defined in Section
4001(a)(3) of ERISA), neither Seller nor any of its Subsidiaries nor any of its
ERISA Affiliates has incurred any withdrawal liability with respect to any
multiemployer plan (and the transactions contemplated by this Agreement shall
not give rise to any such withdrawal liability) or any Liability in connection
with the termination or reorganization of any multiemployer plan and no Benefit
Plan provides health or other welfare benefits to former employees extending
beyond their retirement or other termination of service, other than coverage
mandated by Part 6 of Title I of ERISA or death benefits or retirement benefits
under any Benefit Plan that is an "employee pension plan," as that term is
defined in Section 3(2) of ERISA. All contributions or other amounts payable by
Seller or any of its Subsidiaries or any ERISA Affiliate as of the Effective
Time with respect to each Benefit Plan in respect of current or prior plan years
have been paid or accrued in accordance with GAAP, Section 302 of ERISA and
Section 412 of the Code, and there is no accumulated funding deficiency with
respect to any Benefit Plan. The present value of accrued benefits under each
Benefit Plan which is an employee pension benefit plan, based upon the actuarial
assumptions used for funding purposes in the most recent actuarial report
prepared by such Benefit Plan's actuary with respect to such Benefit Plan, did
not, as of its latest valuation date, exceed the then current value of the
assets of such Benefit Plan allocable to such accrued benefits.

     (b) Neither Seller, nor any of its Subsidiaries, nor any ERISA Affiliate
contributes or has contributed to any "multiemployer plan" as such term is
defined in Section 3(37) of ERISA. Neither Seller nor any of its Subsidiaries
nor any ERISA Affiliate is or was a substantial employer (within the meaning of
Section 4001(a)(2) of ERISA) for any single employer plan that is (or was)
subject to Section 4063 of ERISA.

     (c) To the extent applicable, each Benefit Plan (and its related trust) is
maintained and administered in compliance in all respects with the applicable
provisions of ERISA, the Code and any other laws. Each Benefit Plan (and its
related trust) which is maintained, administered, reported or contributed to as
if qualified under Sections 401(a) or 501(a) of the Code is so qualified and has
received a favorable determination letter from the Internal Revenue Service that
it is so qualified. Except as specified in Schedule 3.11(c), each Benefit Plan
that is an employee benefit plan within the meaning of Section 3(3) of ERISA
(and its related trust) may, by its terms, be amended or terminated, in whole or
in part, at any time and from time to time by Seller (or, as applicable, any of
its Subsidiaries or any ERISA Affiliate) without penalty or cost (other than
out-of-pocket costs customary payable in the Ordinary Course in connection with
the preparation and filing of any such amendment or termination, including
reasonable fees and expenses of counsel).

the meaning of Section 4043 of ERISA has occurred with respect to any such
Benefit Plan, the PBGC has not commenced proceedings for the termination of any
Benefit Plan or the appointment of a trustee with respect to any Benefit Plan,

Benefit Plan. None of the assets of Seller or any of its Subsidiaries or any
ERISA Affiliate is the subject of any Security Interest arising under Section
302 of ERISA or Section 412 of the Code, and no facts or circumstances exist
which could give rise to such Security Interest. Neither Seller nor any of its

such plan, or a written statement that no such determination exists or is
required.

     (f) Neither Seller nor any of its Subsidiaries nor any ERISA Affiliate has
engaged in a transaction in connection with which Seller, any of its
Subsidiaries or any ERISA Affiliate, or any other Person or entity, could be
subject to a Liability under ERISA, or the Code, including, without limitation,
liability under Section 409 of ERISA or a civil penalty assessable pursuant to
Section 502 of ERISA or a tax imposed pursuant to Section 4975 of the Code, and
no event has occurred and no condition exists with respect to any Benefit Plan
that could subject Seller or any of its Subsidiaries or any ERISA Affiliate to
any tax, fine or penalty imposed by the Code or ERISA.

     (g) Except as provided in Schedule 3.11(g), neither the execution and
delivery of this Agreement nor the consummation of the Merger will (i) result in
any payment (including, without limitation, deferred compensation, severance,
unemployment compensation, golden parachute or otherwise) becoming due to any
director, employee, contractor, consultant or other service provider of Seller
or any of its Subsidiaries or any ERISA Affiliate from Seller or any of its
Subsidiaries or any ERISA Affiliate under any Benefit Plan or otherwise, (ii)
increase any benefits otherwise payable under any Benefit Plan or otherwise,
(iii) result in any acceleration of the time of payment or vesting of any such
benefits, or (iv) result in any increase in or acceleration of the contribution
or funding obligation, if any, of Seller or any of its Subsidiaries or any ERISA
Affiliate.

     (h) No Benefit Plan will be amended or terminated on or prior to the
Closing Date without the prior written approval of Buyer. The Seller has made
all contributions and payments required to each Benefit Plan through the
Effective Time, inclusive, or provided for such contributions and payments in

     3.12  Proprietary Rights.  Except as set forth in Schedule 3.12, Seller and
its Subsidiaries own and possess all right, title and interest in, free and
clear of all Security Interests, or have a license or other right to use, all
Proprietary Rights which are used in, or held for use in, the operation of the
business of Seller and its Subsidiaries as presently conducted or as presently
proposed to be conducted and which are material to such presently conducted or
proposed business. Each of Seller and its Subsidiaries has taken all
commercially reasonable action to maintain and protect each item of Proprietary
Rights owned by Seller or any of its Subsidiaries. No item of the Proprietary
Rights set forth in Schedule 3.12 has been adjudicated to be invalid or
unenforceable and, to the knowledge of Seller and its Subsidiaries, no third
party has interfered with, infringed upon, misappropriated, or otherwise come
into conflict with any of such Proprietary Rights. Notwithstanding any other
provision of this Section, Schedule 3.12 lists all of the following items: all
patented and registered Proprietary Rights owned by Seller or any of its
Subsidiaries; all pending patent applications and applications for the
registration of other Proprietary Rights filed by or on behalf of Seller or any
of its Subsidiaries; all trade and corporate names owned or used by Seller or
any of its Subsidiaries; and all joint

                                      A-23
<PAGE>   24

development agreements to which Seller or any of its Subsidiaries is a party
that assign or limit any Proprietary Rights owned or used by Seller or any of
its Subsidiaries. Schedule 3.12 lists all licenses or other written contracts
between Seller or any of its Subsidiaries and any third party regarding any of
the Proprietary Rights (other than computer software) listed on Schedule 3.12.
Neither Seller nor any of its Subsidiaries has interfered with, infringed upon,
misappropriated, or otherwise come into conflict with any Proprietary Right of
any third party as could reasonably be expected to have a Material Adverse
Effect on Seller, and to the knowledge of Seller, neither Seller nor any of its
Subsidiaries will interfere with, infringe upon, misappropriate, or otherwise
come into conflict with any Proprietary Right of any third party as a result of
the continued operation of its businesses as presently conducted and as
presently proposed to be conducted as could reasonably be expected to have a
Material Adverse Effect on Seller. Except as set forth on Schedule 3.12, each
item of Proprietary Rights listed on Schedule 3.12 will be owned or available
for use by Buyer or its Subsidiaries on identical terms and conditions
immediately subsequent to the Effective Time.

     3.13  Year 2000.

     (a) The Seller and the Subsidiaries have conducted an inventory and
assessment (written summaries of which, to the extent prepared, have been
provided to Buyer) of the computer software, computer firmware or computer
hardware (whether general or special purpose) of Seller and each of its
Subsidiaries in order to determine the extent to which such software, firmware
or hardware is not Year 2000 Compliant (as defined below) and to estimate the
cost of rendering such software, firmware or hardware Year 2000 Compliant prior
to January 1, 2000 or such earlier date on which such software, firmware or
hardware may shut down or may produce incorrect calculations or otherwise
malfunction in any material respect. Any failure of the Computer Systems to be
Year 2000 Compliant will not have a Material Adverse Effect on the Seller. The
aggregate amount to be expended by Seller and its Subsidiaries, on a
consolidated basis, during the 12-month period ending December 31, 1999 to
render the Computer Systems Year 2000 Compliant, and to test whether any
Computer System is Year 2000 Compliant, will not have a Material Adverse Effect
on the Seller. For the purposes of this Agreement "Year 2000 Compliant" means
that none of the Computer Systems or Benefit Plan Computer Systems (as defined
below) of a particular Person will, in any material respect, malfunction, cease
to function, generate incorrect data, or produce incorrect results when
processing, receiving, calculating, writing and/or providing (i) date-related
data into and between the twentieth and twenty-first centuries and (ii)
date-related data in connection with any valid date in the twentieth and
twenty-first centuries.

     (b) Seller has made available to Buyer copies of all material in-house
correspondence and memoranda and all material correspondence between the Seller
or any of its Subsidiaries with any customers, insurance company, vendor,
supplier or service provider of Seller and its Subsidiaries concerning whether
such Persons (including Seller or any of its Subsidiaries) are or expect to be
Year 2000 Compliant or whether such Persons expect to be adversely affected by
the failure of any other Person to be Year 2000 Compliant.

     (c) To the knowledge of Seller, no customer, supplier, contractor,
distributor, insurance company, or other vendor or service provider with which
Seller or any of its Subsidiaries transacts business can reasonably be expected
not to be Year 2000 Compliant in any respect that could reasonably be expected
to have a Material Adverse Effect on Seller.

                                      A-24
<PAGE>   25

     (d) To the knowledge of Seller (which for purposes of this Section 3.13(c)
shall include, without limitation, the knowledge of each employee or consultant
of Seller or any of its Subsidiaries that in the ordinary course is engaged in
the administration or operation of any Benefit Plan), the Benefits Plans and
each of the sponsors of and fiduciaries with respect to each Benefit Plan have
conducted an inventory and assessment of the Computer Systems that are material
to the administration or management of any Benefit Plan (including the
management, investment and disposition of Benefit Plan assets, maintained under
a trust or otherwise), including, without limitation, the Computer Systems of
each Benefit Plan, the sponsor(s) of each such Benefit Plan, and third-party
service providers to each such Benefit Plan, and each of the Computer Systems
that are material to the investment of the assets of any of the Benefit Plans
(the "Benefit Plan Computer Systems") in order to determine which parts of the
Benefit Plan Computer Systems are not Year 2000 Compliant. The failure,
individually or in the aggregate, of Benefit Plan Computer Systems to be Year
2000 Complaint will not result in any sponsor or fiduciary of any Benefit Plan
incurring any liability or expense that will have a Material Adverse Effect on
Seller.

     (e) Each Benefit Plan has made available to Buyer copies of all material
in-house correspondence and memoranda and all material correspondence between
such Benefit Plan (including its sponsor(s) and fiduciaries) and its agents,
insurance companies, vendors, suppliers, service providers, participants and
beneficiaries concerning whether such Persons are or expect to be Year 2000
Compliant or whether such Persons expect to be adversely affected by the failure
of any other Person to be Year 2000 Compliant.

     (f) To the knowledge of Seller, no Benefit Plan (including its sponsor(s)
and fiduciaries), and no agent, insurance company, supplier, vendor or service
provider with which such Benefit Plan transacts business, can reasonably be
expected not to be Year 2000 Compliant in any respect that could reasonably be
expected to have a Material Adverse Effect on any Benefit Plan.

     3.14  Inventories.  Except as set forth on Schedule 3.14 and subject to
applicable reserves reflected on Seller's unaudited consolidated balance sheet
as of December 31, 1998, and except for obsolete items and items of
below-standard quality, all of which have been written-off or written-down to
net realizable value on Seller's unaudited consolidated balance sheet as of
December 31, 1998, all items of finished goods reflected on the books of Seller

to be invalid, past due or uncollectible and for which Seller and its
Subsidiaries has created an applicable reserve for bad debts on Seller's
unaudited consolidated balance sheet as of December 31, 1998.

     3.16  Tangible Property.

     (a) Seller or one or more of its Subsidiaries own or lease all buildings,
equipment, and other tangible assets necessary for the conduct of their
businesses as presently conducted and as presently proposed to be conducted.
Schedule 3.16 sets forth a true and complete list of all owned U.S. real
property and owned foreign real property used by Seller or any of its
Subsidiaries. Except as set forth in Schedule 3.16, the identified owner has
good and marketable title to the parcel of real property, free and clear of any
Security Interests, and there are no parties (other than Seller or its
Subsidiaries) in possession of

                                      A-25
<PAGE>   26

such parcel of real property. Schedule 3.16 also sets forth a list of all of the
leased and subleased parcels of real property subject to leases and subleases in
favor of Seller or one or more of its Subsidiaries which evidence leasehold or
subleasehold interests of Seller or its Subsidiaries in such properties and

connection with the Merger.

     (b) Except as set forth in Schedule 3.16, Seller has all easements,
certificates of occupancy, permits, approvals, franchises, authorizations and

hereto, the books and records of Seller and each of its Subsidiaries are
accurate and complete in all material respects, have been maintained in
accordance with GAAP consistently applied, and accurately reflect in all
material respects the ownership, use, and operations of Seller and each of its
Subsidiaries.

     3.18  Brokers' Fees.  None of Seller and its Subsidiaries has any Liability
or obligation to pay any fees or commissions to any broker, finder, or similar
agent with respect to the transactions contemplated by this Agreement.

     3.19  Tax-Free Reorganization Representations.  To Seller's knowledge, it
has not taken any action that would or reasonably could be expected to cause the
Merger to fail to qualify as a "reorganization" within the meaning of Section
368 of the Code. Without limiting the generality of the immediately preceding
sentence:

          (a) There is no intercorporate indebtedness existing between Seller
     and Buyer that was issued, acquired or will be settled at a discount.

          (c) The Merger will be effected for a bona fide business purpose.

          (d) None of the Buyer Shares received by any stockholder/employee of
     Seller pursuant to the Merger are, or will be, separate consideration for,
     or allocable to, any employment, consulting or similar arrangement. The
     compensation paid to any stockholder/employee of Seller pursuant to any
     such employment, consulting or similar arrangement (including any covenant
     not to compete) is or will be for services actually rendered and performed
     (or not competing), and will be commensurate with amounts paid to third
     parties bargaining at arms length for similar services.

          (e) As at the Effective Time, Seller will hold at least ninety percent
     (90%) of the fair market value of its net assets and at least seventy
     percent (70%) of the fair market value of its gross assets held immediately
     prior to the Effective Time. For purposes of this representation, amounts
     paid or expected to be paid by Seller or the Surviving Corporation to
     dissenters, amounts paid by Seller to shareholders who receive cash or
     other property, amounts used or expected to be used by Seller or the
     Surviving Corporation to pay Seller's or any Seller Stockholder's
     reorganization expenses, and all redemptions and distributions (except for
     regular, normal dividends) made by Seller, will be included as assets of
     Seller immediately prior to the Merger.

          (f) In the Merger, Seller Shares representing control of Seller, as
     defined in Section 368(c) of the Code, will be exchanged for Buyer Shares.
     For purposes of this

                                      A-26
<PAGE>   27

     representation, Seller Shares exchanged for cash from Buyer will be treated
     as outstanding Seller Shares at the Effective Time.

     outstanding any warrants, options, convertible securities, or any other
     type of right pursuant to which any Person could acquire stock in Seller
     that, if exercised or converted, would affect Buyer's acquisition or
     retention of control of Seller, as defined in Section 368(c) of the Code.

          (h) Immediately after the Effective Time, the fair market value of the
     assets of Seller will exceed the sum of its liabilities, plus the amount of
     liabilities, if any, to which the assets are subject.

          (i) Seller will not redeem any Seller Shares, or make an extraordinary
     distribution with respect to any Seller Shares prior to, or in connection
     with, the Merger within the meaning of Temporary Regulation sec.1.368-1T.

     3.20  Pooling of Interest Treatment.  To Seller's knowledge, it has not
taken any action that would or reasonably could be expected to cause the Merger
to fail to qualify for "pooling of interests" accounting treatment under
Accounting Principles Board Opinion No. 16. Each of the Affiliates of Seller,
within the meaning of SEC Accounting Staff Releases Nos. 130 and 135, is listed
on Schedule 3.20.

could be expected to have a Material Adverse Effect on Seller; (vii) any
instrument or Contract whereby Seller or any of its Subsidiaries indemnifies or
guarantees any loss or Liability which, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on Seller; (viii) any
Contract under which Seller or any of its Subsidiaries could have Liabilities or
obligations in the future relating to the acquisition or disposition of material
assets by way of merger, consolidation, purchase, sale or otherwise, or granting
to any Person a right at such person's option to purchase or acquire any
material asset or property of Seller or any interest therein (not including
dispositions of inventory in the Ordinary Course); and (ix) any other Contract
(or group of related contracts) the performance of which involves consideration
in excess of $250,000.

     (b) To Seller's knowledge, the Grace Agreement is the valid and legally
binding obligation of the parties thereto, is enforceable in accordance with its
terms and conditions, and has not been amended or modified in any manner that
would affect the rights of Seller or any of its Subsidiaries under Sections
14.05 thereof. To Seller's knowledge, there are no existing facts or
circumstances which give Seller any reason to believe that the Selling Companies
(as defined in the Grace Agreement) would not satisfy their obligation to
indemnify Seller and the other members of the Buyer Group (as defined in the
Grace Agreement) in accordance with the terms of Section 14.05 of the Grace
Agreement.

Subsidiaries or (ii) conflict with, result in a breach of, constitute a default

party or by which it is bound or to which any of its material assets is subject,
except for any such matters identified on Schedule 5.3. Other than in connection
with the provisions of the HSRA, the federal and state securities laws and the
NYSE Rule, neither Buyer nor any of its Subsidiaries needs to give any notice
to, make any filing with, or obtain any authorization, consent, or approval of
any government or governmental agency or other Person in order for the Parties
to consummate the Merger, except as set forth on Schedule 5.3.

     5.4  Capitalization.  The authorized capital stock of Buyer consists of
77,000,000 shares of capital stock, consisting of 75,000,000 of common stock, no
par value per share, of which 25,136,349 shares are issued and outstanding as of
the date of this Agreement, and 2,000,000 shares of serial preferred stock, none
of which is outstanding. Except as set forth on Schedule 5.4, neither Buyer nor
any of its Subsidiaries has (i) any shares of common stock or preferred stock
reserved for issuance, or (ii) any Contract to which Buyer or any of its
Subsidiaries or, to Buyer's knowledge, any Affiliate of Buyer is a party or
subject relating to its capital stock or otherwise representing a right to
receive any of its capital stock, nor are there any pending or, to Buyer's
knowledge, threatened claims or demands for, a direct or indirect equity
interest in Buyer or any Subsidiary, including, without limitation, stock
appreciation, phantom stock, profit participation or similar rights. All of the
issued and outstanding shares of Buyer Common Stock have been duly authorized,
validly issued, are fully paid and are nonassessable. All Buyer Shares have been
duly authorized and, upon consummation of the Merger, will be validly issued,
fully paid and nonassessable. Notwithstanding the foregoing, Seller acknowledges
that, after the date hereof and prior to the Effective Time, Buyer may issue
additional shares of Buyer Common Stock. The authorized capital stock of the
Merger Sub is owned in its entirety by Buyer.

     5.5  SEC Filings.  Buyer has made all filings with the SEC that it has been
required to make since December 31, 1995 under the Securities Act and the
Exchange Act (including any exhibits and amendments thereto). Each such filing
complied with the Securities Act and the Securities Exchange Act in all material
respects when filed. No such filing, when filed, contained any untrue statement
of a material fact or omitted to state a material fact necessary to make the
statements made therein, in light of the circumstances under which they were
made, not misleading.

     5.6  Financial Statements.  Buyer has filed an Annual Report on Form 10-K
for the fiscal year ended March 31, 1998 and a Quarterly Report on Form 10-Q for
each of the fiscal quarters ended June 30, 1998 and September 30, 1998 (together
the "Buyer Public Reports"). The financial statements included in Buyer Public
Reports have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods covered thereby unless noted therein, present fairly the
financial condition of Buyer and its Subsidiaries as of the indicated dates and
the results of operations of Buyer and its Subsidiaries for the indicated
periods, are consistent with the books and records of Buyer and its
Subsidiaries, and comply in all material respects with the provisions of
Regulations S-K and S-X of the Securities Act. Attached as Schedule 5.6 are the
unaudited consolidated balance sheet, income statement and cash-flow statement
of Buyer and its Subsidiaries as of and for the three and nine-month periods
ended December 31, 1998, which have been prepared in accordance with GAAP on a
basis consistent with Buyer Public Reports with the exception of footnotes,
present fairly the financial condition of Buyer and its Subsidiaries as of the
indicated dates and the results of operations of Buyer and its Subsidiaries for
the indicated periods, and are consistent with the books and records of Buyer

proceedings, claims, complaints, injunctions, orders or investigations by or
before any Governmental Entity pending or, to Buyer's knowledge, threatened
against Buyer or its Subsidiaries seeking to enjoin any aspect of the Merger. To
Buyer's knowledge, there are no existing facts or circumstances which give any
reason to believe that any such action, suit, proceeding, hearing or
investigation may be brought or threatened against Buyer or any of its
Subsidiaries.

     5.8  Absence of Certain Developments.

     (a) Except as disclosed in Schedule 5.8(a), since March 31, 1998 no event
has occurred which has had or reasonably could be expected to have a Material
Adverse Effect on Buyer.

     (b) Except as disclosed in Schedule 5.8(b) or the Financial Statements, and
except for this Agreement and the Merger, since March 31, 1998, each of Buyer
and its Subsidiaries has been operated in the Ordinary Course.

     5.9  Taxes.

     (a) Except as set forth on Schedule 5.9(a), all Taxes owed by Buyer and
each of its Tax Affiliates, whether or not shown on any Tax Return, have been
timely paid or are not yet due and payable.

     (b) Except as set forth on Schedule 5.9(b):

          (i) neither Buyer nor any of its Subsidiaries (A) is or has been a
     member of an affiliated group filing a consolidated federal income Tax
     Return (other than a group of the common parent of which was Buyer) or (B)
     has any Liability for the Taxes of any Person (other than Buyer and its
     Subsidiaries) under Treas. Reg. sec.1.1502-6 (or any similar provision of
     state, local or foreign law), as a transferee or successor, by contract, or
     otherwise;

          (ii) Buyer and each of its Tax Affiliates has complied with all
     applicable laws, rules and regulations relating to the payment and
     withholding of Taxes and has timely and properly withheld from employee
     wages and paid over to the proper governmental authorities all amounts
     required to be so withheld and paid over under all applicable laws;

          (iii) there are no liens for Taxes on any assets of Buyer or any of
     its Tax Affiliates except liens for Taxes not yet due.

          (iv) neither Buyer nor any of its Tax Affiliates is a party to or
     bound by any Tax indemnification, Tax allocation or Tax sharing agreement
     with any Person or has any current or potential contractual obligation to

     Effective Time will maintain on its books and records reserves adequate to
     pay all Taxes accrued but not yet due and payable in accordance with GAAP,

     required. Neither Buyer nor any of its Subsidiaries is a party to any
     agreement, contract or arrangement that would result, separately or in the
     aggregate, in the payment of any "excess parachute payment" within the
     meaning of Section 280G of the Code, or in the payment of compensation that
     is not fully deductible pursuant to Section 162(m) of the Code, as a result
     of the Merger.

     5.10  Environmental, Health, and Safety Matters.  Except as set forth on
Schedule 5.10, (i) Buyer has complied with, and is in compliance with, the
Environmental, Health, and Safety Requirements, in all material respects, (ii)
without limiting the generality of the foregoing, Buyer has obtained and
complied with, and is in compliance with, in all material respects, all permits,
licenses and other authorizations that are required pursuant to the
Environmental, Health, and Safety Requirements for the occupation of their
facilities and the operation of their business, (iii) Buyer has not received any
notice regarding any actual or alleged material violation of Environmental,
Health, and Safety Requirements, or any material Liability or potential
Liability arising under the Environmental, Health, and Safety Requirements
(including any investigatory, remedial or corrective obligations) (iv) Buyer has
not treated, stored, disposed of, arranged for or permitted the disposal of,
transported, handled, or released any Hazardous Material or owned or operated
any property or facility (and no such property or facility is contaminated by
any Hazardous Material) in a manner that has given or reasonably could be
expected to give rise to any material Liability, including Liability for
response costs, corrective action costs, personal injury, property damage,
natural resources damages or attorney fees, pursuant to the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, the
Solid Waste Disposal Act, as amended, or any other Environmental, Health, and
Safety Requirements, and (v) Buyer has not, either expressly or by operation of
law, assumed, undertaken or otherwise become subject to any material Liability
of any other Person relating to Environmental, Health, and Safety Requirements.

     5.11  Employee Benefit Plans.

     (a) All contributions or other amounts payable by Buyer or any ERISA
Affiliate as of the Effective Time with respect to each Benefit Plan in respect
of current or prior plan years have been paid or accrued in accordance with
GAAP, Section 302 of ERISA and Section 412 of the Code, and there is no
accumulated funding deficiency with respect to any Benefit Plan. The present
value of accrued benefits under each Benefit Plan which is an employee pension
benefit plan, based upon the actuarial assumptions used for funding purposes in
the most recent actuarial report prepared by such Benefit Plan's actuary with
respect to such Benefit Plan, did not, as of its latest valuation date, exceed
the then current value of the assets of such Benefit Plan allocable to such
accrued benefits.

     (b) To the extent applicable, each Benefit Plan (and its related trust) is
maintained and administered in material compliance in all respects with the
applicable provisions of ERISA, the Code and any other laws. Each Benefit Plan
(and its related trust) which is maintained, administered, reported or
contributed to as if qualified under Sections 401(a) or 501(a) of the Code is so
qualified and has received a favorable determination letter from the Internal
Revenue Service that it is so qualified. Each Benefit Plan (and its related
trust) may, by its terms, be amended or terminated, in whole or in part, at any
time and from time to time by Buyer (or, as applicable, any ERISA Affiliate)
without penalty or cost.

     (c) No Liability to the Pension Benefit Guaranty Corporation (the "PBGC")
(except for routine payment of premiums) has been incurred with respect to any
Benefit Plan that is subject to Title IV of ERISA (and no fact or circumstance
exists which could give rise to any such liability), no reportable event within
the meaning of Section 4043 of ERISA has occurred with respect to any such
Benefit Plan, the PBGC has not commenced proceedings for the termination of any
Benefit Plan or the appointment of a trustee with respect to any Benefit Plan,
and no fact or circumstance exists which can be expected to

                                      A-33
<PAGE>   34

cause the PBGC to commence any proceedings under Title IV of ERISA or otherwise
with respect to any Benefit Plan. None of the assets of Seller or any ERISA
Affiliate is the subject of any Security Interest arising under Section 302 of
ERISA or Section 412 of the Code, and no facts or circumstances exist which
could give rise to such Security Interest. Neither Buyer nor any ERISA Affiliate
has been required to post any security under Section 307 of ERISA or Section
401(a) of the Code, and no facts or circumstances exist which could give rise to
such posting of security.

     (d) Neither Buyer nor any ERISA Affiliate has engaged in a transaction in
connection with which Buyer or any ERISA Affiliate, or any other Person or
entity, could be subject to a material Liability under ERISA, or the Code,
including, without limitation, liability under Section 409 of ERISA or a civil
penalty assessable pursuant to Section 502 of ERISA or a tax imposed pursuant to
Section 4975 of the Code, and no event has occurred and no condition exists with
respect to any Benefit Plan that could subject Buyer or any ERISA Affiliate to
any tax, fine or penalty imposed by the Code or ERISA.

     5.12  Broker's Fee.  None of Buyer and its Subsidiaries has any Liability
or obligation to pay any fees or commissions to any broker, finder, or similar
agent with respect to the transactions contemplated by this Agreement.

     5.13  Tax-Free Reorganization Representations.  To Buyer's knowledge, it
has not taken any action that would or reasonably could be expected to cause the
Merger to fail to qualify as a "reorganization" within the meaning of Section
368 of the Code, and does not intend to take any such action. Without limiting
the generality of the immediately preceding sentence:

          (a) Except with respect to the payment of cash in lieu of fractional
     share interests pursuant to Section 2.4(g), neither Buyer nor any related
     Person (within the meaning of Treas. Reg. sec.1.368-1(e)(3)) has any plan
     or intention to reacquire any of the Buyer Shares that will be issued in
     the Merger pursuant to either Buyer Warrant.

          (b) There is no intercorporate indebtedness existing between Buyer and
     Seller that was issued, acquired or will be settled at a discount.

          (c) Neither Buyer nor Merger Sub is an investment company as defined
     in Section 368(a)(2)(F)(iii) and (iv) of the Code.

          (d) Merger Sub will have no liabilities that will be assumed by or
     transferred to Seller in the Merger.

          (e) Prior to and through the Effective Time of the Merger, Buyer will
     be in control of Merger Sub within the meaning of Section 368(c) of the
     Code.

          (f) Buyer has no plan or intention to: (i) liquidate the Surviving
     Corporation, (ii) merge the Surviving Corporation with and into another
     corporation other than Merger Sub, (iii) sell or otherwise dispose of the
     Seller Shares, or (iv) cause the Surviving Corporation to sell or otherwise
     dispose of any of its assets, except for dispositions made in the ordinary
     course of business or transfers described in Section 368(a)(2)(C) of the
     Code.

          (g) Neither Buyer nor any related Person (within the meaning of Treas.
     Reg. sec.1.368-1(e)(3)) has acquired or will acquire any Seller Shares in
     anticipation of the Merger.

          (h) Buyer does not own, and has not owned during the past five years,
     any Seller Shares.

                                      A-34
<PAGE>   35

          (i) The Merger will be effected for a bona fide business purpose.

          (j) None of the Buyer Shares received by any stockholder/employee of
     Seller pursuant to the Merger are, or will be, separate consideration for,
     or allocable to, any employment, consulting or similar arrangement. The
     compensation paid to any stockholder/employee of Seller pursuant to any
     such employment, consulting or similar arrangement (including any covenant
     not to compete) is or will be for services actually rendered and performed
     (or not competing), and will be commensurate with amounts paid to third
     parties bargaining at arms length for similar services.

          (k) Buyer has no plan or intention to cause the Surviving Corporation
     to issue Seller Shares after the Merger that would result in Buyer losing
     control of the Surviving Corporation within the meaning of Section 368(c)
     of the Code.

          (l) Buyer presently intends that after the Merger it will cause the
     Surviving Corporation to continue the historic business of Seller and/or to
     use a significant portion of Seller's business assets in a business.

     5.14  Pooling of Interest Treatment.  To Buyer's knowledge, it has not
taken any action that would or reasonably could be expected to cause the Merger
to fail to qualify for "pooling of interests" accounting treatment under
Accounting Principles Board Opinion No. 16.

     5.15  Disclosure.  No representation or warranty of Buyer contained in this
Agreement or any schedule, attachment or exhibit hereto, and no statement
contained herein or in any certificate or document furnished to Buyer pursuant
to the transactions contemplated hereby, contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances in which
they were made, not misleading.

reasonably be expected to result in any of the conditions to the Merger as set
forth in Section 7 not being satisfied or in a violation of this Agreement; or
take or omit to be taken any action which reasonably could be expected to have a
Material Adverse Effect on Seller.

     6.5  Covenants of Buyer.  Prior to the Closing, except as otherwise
expressly provided for herein, Buyer shall, and shall cause its Subsidiaries to:

          (a) not take any action that is intended or may reasonably be expected
     to result in any of its representations and warranties set forth in this
     Agreement being or becoming untrue in any material respect, or in any of

     or in a violation of any provision of this Agreement, except, in every
     case, as may be required by applicable law;

          (b) not take any other action that would materially impede the ability

     materially adversely affect Buyer's ability to consummate the transactions

<PAGE>   41

          (e) not consolidate with or merge into any other Person or convey,

     Buyer hereunder;

          (f) pay their own expenses in connection with the Merger; and

          (g) not authorize or enter into any agreement or commitment to take
     any action inconsistent with any of the foregoing.

Further, prior to the Closing, without the prior written consent of Seller or as
otherwise expressly provided for herein, Buyer will not, and will not permit any
of its Subsidiaries, to enter into any Contract or take any other action which,
if entered into or taken prior to the date of this Agreement, would cause any
representation or warranty of Buyer to be untrue in any respect or be required
to be disclosed on any Schedule; or take any action that is intended or may
reasonably be expected to result in any of the conditions to the Merger as set
forth in Section 7 or in a violation of this Agreement.

     6.6  Access.  (a) Seller shall make available to Buyer all information
regarding Seller that Buyer reasonably may request and shall authorize all
reasonable visits to Seller's premises to make such investigations of the
business, properties, books and records of Seller and its Subsidiaries
(including without limitation Phase I and Phase II environmental assessments and
other environmental due diligence) as Buyer reasonably may request. Buyer agrees
to coordinate closely all such activities with Seller's President or Chief
Financial Officer and to conduct any such inquiries with appropriate discretion
and sensitivity to Seller's relationships with its employees, customers and
suppliers.

     (b) Upon reasonable notice, Buyer shall, within a reasonable period of time
prior to the Closing, afford Seller and its officers, employees, counsel,
accountants and other authorized Representatives, such access as is reasonably
necessary to confirm that the representations and warranties of Buyer made
herein are true and correct in all material respects. Buyer shall furnish
promptly to Seller a copy of each application, report, schedule, correspondence
and other document filed by Buyer with or received by Buyer from any
Governmental Entity in connection with the transactions contemplated hereunder,
and Buyer agrees to notify Seller by telephone within twenty-four (24) hours of
receipt of any adverse oral communication from any Governmental Entity regarding
the outcome of any regulatory applications required in connection with the
Merger.

     (c) Nothing in this Section 6.6 shall require any Party or any of its
Subsidiaries to provide access to or to disclose information where such access
or disclosure would jeopardize the attorney-client privilege of the Person in
possession or control of such information or would contravene any law, rule,
regulation, order, judgment, decree, fiduciary duty or binding agreement entered
into prior to the date of this Agreement. The Parties will make appropriate
substitute disclosure arrangements under circumstances in which the restrictions
of the immediately preceding sentence apply.

     (d) Each Party acknowledges that certain of the information made available
to it pursuant to this Section 6.6 and otherwise in connection with the Merger
may be confidential, proprietary or otherwise nonpublic, and each Party agrees,
for itself and for each of its Representatives, that it (i) shall hold in
confidence all confidential information received by it from or with regard to
the other Party ("Confidential Information") subject to the terms of this
Section 6.6, (ii) shall disclose such Confidential Information only to those of
its Representatives and, in the case of Buyer, its current or prospective
lenders, and other sources of capital, in each case having a need to know the
same for purposes of evaluating, negotiating or implementing financing for
Buyer, and (iii) shall inform each

                                      A-41
<PAGE>   42

Representative or current or prospective lender or investor to whom Confidential
Information is disclosed that such information is confidential and direct such
Representative or current or prospective lender or investor not to disclose the
same. Each Party shall remain responsible for any disclosure of Confidential
Information by any of its Representatives or current or prospective lender or
investors. Each Party further agrees that, upon the request of the other Party
given following the termination of this Agreement for any reason, the receiving
Party and each of its Representatives either shall return to the requesting
Party all Confidential Information received by the receiving Party and its
Representatives (including all compilations, analyses or other documents
prepared by it that contain Confidential Information) or shall certify that the
same has been destroyed. As used herein, Confidential Information shall not
include (i) information that is or becomes generally available to the public
other than as a result of a breach of this Agreement, (ii) information that the
receiving Party demonstrates was known to it on a non-confidential basis prior
to receiving such information from the other Party, (iii) information that the
receiving Party develops independently without relying on Confidential
Information, and (iv) information that becomes available to the receiving Party
on a non-confidential basis from another source if the source was not known to
or not reasonably believed by the receiving Party to be subject to any
prohibition against disclosing such information.

     6.7  Notice of Developments.  Each Party shall promptly advise the other
Party of any change or event having a Material Adverse Effect on it or its
ability to perform its obligations under this Agreement or which it believes
would or may be reasonably likely to cause or constitute a material breach of
any of its representations, warranties or covenants contained herein or to
preclude the satisfaction of one or more of the conditions set forth in Section
7; provided, however, that any such disclosure shall not have any effect for the
purpose of determining the accuracy of any representation or warranty when made,
for determining satisfaction of the conditions set forth in Section 7, or for
determining the compliance by Seller with any other provision of this Agreement.

     6.8  Acquisition Proposals.  Seller shall not, and it shall not authorize
or permit any of its Subsidiaries, officers, directors, employees, Affiliates,
stockholders or any Representative retained by Seller or its Subsidiaries,
directly or indirectly, to (i) solicit, initiate or knowingly encourage or
induce the making of any Acquisition Proposal, (ii) negotiate with any third
party with respect to any Acquisition Proposal, (iii) endorse or recommend the
Acquisition Proposal of any Person other than the Buyer or any of its
Subsidiaries or (iv) enter into any Contract with any third party with the
intent to effect any Acquisition Proposal.

     6.9  Board of Directors.  CVC shall have the right to designate one (1)
director to serve on Buyer's Board of Directors from and after the Effective
Time, and Buyer's Board of Directors shall take all such action reasonably
necessary to cause and maintain such designation, so long as at all times from
and after the Effective Time each of the following conditions is satisfied: (i)
CVC owns shares of Buyer Common Stock constituting forty percent (40.0%) or more
of the total number of Buyer Shares issued to CVC in the Merger (as adjusted for
any Recapitalization) and (ii) CVC owns shares of Buyer Common Stock
constituting two percent (2.0%) or more of the shares of Buyer Common Stock
outstanding from time to time. A condition to the election of the CVC designee
is the agreement of such designee to resign at the request of Buyer's Board of
Directors if the either of the conditions set forth in the immediately preceding
sentence is not satisfied. Buyer shall use all commercially reasonable efforts
to maintain directors' and officers' liability insurance covering the CVC
director designee, and in no event shall such

                                      A-42
<PAGE>   43

directors' and officers' liability insurance applicable to the CVC director
designee be less favorable than the directors' and officers' liability insurance
covering Buyer's directors generally. Buyer shall reimburse such designee for
any reasonable out-of-pocket expenses incurred in connection with his or her
position on the Board of Directors in accordance with Buyer's customary
practices and shall pay such designees any fees or other compensation comparable
to other non-executive directors of Buyer.

     6.10  Financing.  Buyer shall use all commercially reasonable efforts to
obtain, on terms satisfactory to Buyer, debt financing on or prior to the
Closing Date in an amount not less than the amount required to refinance all
financial indebtedness of Seller and its Subsidiaries under the Credit
Agreements, the Senior Credit Notes and the 10% PIK Subordinated Notes and to
provide for the ordinary working capital needs of Seller and its Subsidiaries.
Buyer shall deliver to Seller true and correct copies of the fully executed and
delivered definitive financing agreements with respect thereto on or before the
Closing Date. Buyer shall use all commercially reasonable efforts to cause it
and its Subsidiaries to satisfy on or before the Closing Date all requirements
of the definitive financing agreements which are conditions to closing the
transactions constituting the financing and to drawing the cash proceeds
thereunder. Seller and its Subsidiaries shall use all commercially reasonable
efforts to cooperate with Buyer to facilitate such financing.

     6.11  Press Releases and Public Announcements.  Other than required by this
Agreement, no Party shall issue any press release or make any public
announcement (including filings with the SEC or NYSE) prior to the Effective
Time and relating to the subject matter of this Agreement without the prior
written approval of the other Parties; provided, however, that any Party may
make any public disclosure it believes in good faith is required by applicable
law or any listing or trading agreement concerning its publicly-traded
securities (in which case the disclosing Party will use all commercially
reasonable efforts to advise the other Parties prior to making the disclosure).

     6.12  Covenants of CVC.

     (a) Prior to the Closing, without the prior written consent of Buyer or as
otherwise expressly provided herein, CVC will not, and will not permit any of
its Affiliates to, enter into any Contract or take any other action which, if
entered into or taken prior to the date of this Agreement, would cause any
representation or warranty of Seller or CVC in Article 3 or Article 4 to be
untrue in any respect or be required to be disclosed on any Schedule; or take
any action that is intended or may reasonably be expected to result in any of
the conditions to the Merger as set forth in Section 7 not being satisfied or in
a violation of this Agreement; or take or omit to be taken any action which
reasonably could be expected to have a Material Adverse Effect on Seller.

     (b) CVC shall use its best efforts to cause Seller to obtain Seller
Shareholder Approval and to cause the condition set forth in Section 7.2(g) to
be satisfied, including, with respect to Section 7.2(g), enforcing to the extent
necessary the waiver of dissenter's rights provided in the Seller Stockholder
Agreement. Without limiting the scope of the immediately preceding sentence, so
long as this Agreement has not been terminated in accordance with the terms CVC
shall vote or cause to be voted all of the CVC Shares that are Seller Voting
Shares and that are owned by CVC as of the record date for Seller Stockholder
Approval, for the approval of this Agreement, and shall vote, or cause to be
voted, all such CVC Shares against the approval of any Acquisition Proposal
providing for a merger, acquisition, consolidation, sale of a material amount of
assets or other business combination of Seller or any of its Subsidiaries with
any Person other than Buyer or any of its Subsidiaries.

                                      A-43
<PAGE>   44

     (c) So long as this Agreement has not been terminated in accordance with
the terms hereof, CVC will not sell, assign, transfer or otherwise dispose of
(including, without limitation, by the creation of a Security Interest), or
permit to be sold, assigned, transferred or otherwise disposed of, any of the
CVC Shares, whether such CVC Shares are held on the date of this Agreement or
are subsequently acquired, whether pursuant to the exercise of stock options or
otherwise, except (i) transfers by operation of law (in which case this
Agreement shall bind the transferee), and (ii) as Buyer may otherwise agree in
its sole discretion.

     (d) CVC agrees that, so long as this Agreement has not been terminated in
accordance with the terms hereof, CVC shall, and shall instruct each of its
Representatives and Affiliates to, cease and refrain from any and all
activities, discussions, negotiations, providing any information with respect
to, or other actions with any Person other than Buyer or any of its Subsidiaries
or any of their respective Representatives with respect to any Acquisition
Proposal other than the Merger.

     (e) From the date that is thirty (30) days prior to the Effective Time, CVC
will not sell, transfer or otherwise dispose of, or reduce the risk of ownership
with respect to, any CVC Share and will not sell, transfer or otherwise dispose
of, or reduce the risk of ownership with respect to, any Buyer Shares received
by CVC in the Merger or other shares of Buyer Common Stock until after such time
as results covering at least thirty (30) days of combined operations of Buyer
and Seller have been published by Buyer, in the form of a quarterly earnings
report, an effective registration statement filed with the Commission, a report
to the Commission on Form 10-K, 10-Q, or 8-K, or any other public filing or
announcement which includes the results of at least thirty (30) days of combined
operations as contemplated by and in accordance with SEC Accounting Series
Release No. 135.

          (d) Seller shall have received a letter, in form and substance
     acceptable to it, from PricewaterhouseCoopers, LLP, dated the Closing Date,
     substantially to the effect that, on the basis of a review of the Agreement
     and the Merger contemplated hereby, in such accountants' unqualified
     opinion, Accounting Principles Board Opinion No. 16 provides that the
     Merger may be accounted for as a pooling of interests.

     addressed to, and in form and substance reasonably satisfactory to, Seller;

          (f) Seller shall have received an opinion, dated as of the Closing

     Seller, substantially to the effect that, on the basis of facts and
     representations set forth therein, or set forth in writing elsewhere and
     referred to therein, for federal income tax purposes the Merger constitutes
     a reorganization within the meaning of Section 368(a) of the Code.

          (g) Buyer shall have taken all steps necessary to cause to be elected,
     effective not later than the Effective Time, the Person designated by CVC
     pursuant to Section 6.9;

          (i) Buyer shall have executed and delivered to CVC the Registration
     Rights Agreement.

     SECTION 8.  Indemnification.

     8.1  Agreements to Indemnify.

     (a) As used in this Section 8:

     judgments, orders, decrees, rulings, damages, dues, penalties, fines,
     costs, amounts paid in settlement, Liabilities, obligations, Taxes, liens,
     losses, expenses, and fees, including court costs and attorneys' fees and

     cleanups ordered by federal, state, local, or foreign governments (or any
     agencies thereof).

          (ii) "Indemnifying Party" means the party obligated to provide
     indemnification under Sections 8.1(b), (c) or (d).

          (iii) "Indemnified Party" shall mean a party entitled to
     indemnification under Sections 8.1(b), (c), or (d).

     (b) On the terms and subject to the limitations set forth in this Section 8
and the Escrow Agreement, the Escrow Agent, solely on behalf of the Persons
receiving Buyer Shares in connection with the Merger and the holder of the
Escrow Warrant, and not individually, shall indemnify, defend and hold harmless
Buyer and its Subsidiaries and their Representatives from and against any and
all Damages incurred in connection with or arising out of or resulting from or
incident to (i) any breach of any warranty, or the

                                      A-47
<PAGE>   48

inaccuracy of any representation made by Seller in or pursuant to this
Agreement, or (ii) any breach of any other covenant or agreement made by Seller
in or pursuant to this Agreement.

     (c) On the terms and subject to the limitations set forth in this Section
8, Buyer shall indemnify, defend and hold harmless Seller and the Seller
Stockholders and their respective Subsidiaries and Representatives from and
against any and all Damages incurred in connection with or arising out of or
resulting from or incident to (i) any breach of any or warranty, or the
inaccuracy of any representation, made by Buyer in or pursuant to this
Agreement, or (ii) the breach of any other covenant or agreement made by Buyer
in or pursuant to this Agreement.

     (d) On the terms and subject to the limitations set forth in this Section 8
and the Escrow Agreement, the Escrow Agent, solely on behalf of CVC, and not
individually, shall indemnify, defend and hold harmless Buyer and its
Subsidiaries and their respective Representatives from and against any and all
Damages incurred in connection with or arising out of or resulting from or
incident to (i) any breach of any or warranty, or the inaccuracy of any
representation, made by CVC in or pursuant to this Agreement, or (ii) the breach
of any other covenant or agreement made by CVC in or pursuant to this Agreement.

     (e) Any payment made by the Escrow Agent on behalf of CVC or any other
Seller Stockholder pursuant to the indemnification obligations provided for in
this Section 8 shall constitute a reduction in the consideration paid by Buyer
in the Merger. Any payment made by Buyer pursuant to the indemnification
obligations provided for in this Section 8 shall constitute an addition to the
consideration paid by Buyer.

     8.2  Limitations on Indemnification.

     (a) None of the parties hereto shall be liable to the other pursuant to the
indemnification provisions of Sections 8.1(b), (c) or (d) unless it receives
notice from the other party of its claim for indemnification hereunder within
twelve (12) months after the Closing Date; or in the case of the representations
of Seller set forth in Sections 3.6 and 3.9 and of Buyer under Sections 5.6 and
5.9 as to which the notice must be received by the later of (x) twelve (12)
months after the Closing Date or (y) by April 30, 2000 or such later date as the
audit of Buyer's financial statements for the year ended March 31, 2000 is
complete.

     (b) Indemnification payments due under Sections 8.1 shall be reduced by (i)
any insurance proceeds received by the Indemnified Party with respect to those
Damages which relate to the indemnity claim and which proceeds are received
under an insurance policy of Seller or any of its Subsidiaries in effect as of
the date of this Agreement; provided that this Section 8.2(b) shall not obligate
Buyer or any of its Subsidiaries to obtain any insurance coverage or, if already
obtained, to maintain the effectiveness of such insurance or to make any claim
thereunder; and (ii) the amount of any Tax savings realized by the indemnified
party with respect to those Damages which relate to the indemnity claim (net of
any increased Tax Liability which may result from the receipt of an indemnity
payment under Sections 8.1(b), 8.1(c) or 8.1(d)); provided that future Tax
deductions and Tax Liability will be discounted at the prime rate of interest
reported in the Wall Street Journal at the time the indemnification payment
pursuant to this Section 8 is made.

     (c) Pursuant to claims for indemnification of the type referred to in
Sections 8.1(b), 8.1(c) or 8.1(d), an Indemnifying Party shall only be liable to
an Indemnified Party to the

                                      A-48
<PAGE>   49

extent the aggregate amount of such claims by the Indemnified Party for
indemnification exceeds Two Million Dollars ($2,000,000) in the aggregate (the
"Indemnity Threshold"), whereupon only the amount of such claims in excess of
the Indemnity Threshold shall be recoverable in accordance with the terms
hereof. For purposes of the applying the Indemnity Threshold to Seller
Stockholder claims under Section 8.1(c), all Seller Stockholders shall be
treated as a single Indemnified Party.

     (d) If the Merger has occurred, (i) the aggregate liability of the Seller
Stockholders for any and all Damages arising from indemnification claims under
Section 8.1(b) shall not exceed the value of the Escrow Fund (as defined in the
Escrow Agreement), (ii) the aggregate liability of Buyer for any and all Damages
arising from indemnification claims under Section 8.1(c) shall not exceed the
aggregate Current Market Price of the Escrow Shares as of the Closing Date, and
(iii) the liability of CVC for any and all Damages arising from indemnification
claims under Section 8.1(b) or Section 8.1(d), in the aggregate, shall not
exceed the value of Escrow Account (as defined in the Escrow Agreement) of CVC
and each Escrow Account Beneficiary, if any, who is a successor or assignee of
CVC under the Escrow Agreement.

     (e) If the Merger has occurred, any indemnification payment owed by Buyer
pursuant to Section 8.1(c) shall be payable solely in additional shares of Buyer
Common Stock with the value of such shares being deemed to be equal to the
Current Market Price of Buyer Common Stock as of the Closing Date.

     (f) The indemnification provided for in this Section 8 shall be the sole
and exclusive remedy of Buyer, Merger Sub, Seller, the Seller Stockholders and
CMP, for any and all Damages incurred in connection with or arising out of or
resulting from or incident to any breach of any warranty, or the inaccuracy of
any representation made any Party in or pursuant to this Agreement, or any
breach of any other covenant or agreement made by any Party in or pursuant to
this Agreement or otherwise related to or arising out of the Merger. Without
limiting the scope of the immediately preceding sentence, except as expressly
set forth in this Section 8 and subject only to the occurrence of the Effective
Time, each Party does hereby irrevocably and absolutely waive and release, to
the fullest extent permitted under law, any and all claims, demands, damages,
debts, liabilities, accounts, reckonings, obligations, costs, expenses, liens,
actions and causes of action of every kind and nature whatsoever, which it/he
now has, own or holds, or at any time heretofore ever had, owned or held, or
could, shall or may hereafter have, own or hold, whether now known or unknown,
suspected or unsuspected, against any other Party or other Seller Stockholder
incurred in connection with or arising out of or resulting from or incident to
any breach of any warranty or the inaccuracy of any Party in or pursuant to this
Agreement or any breach of any other covenant or agreement made by any Party in
or pursuant to this Agreement or otherwise related to or arising out of this
Agreement or the Merger.

     8.3  Method of Asserting and Resolving Claims.

     (a) All claims for indemnification by Buyer pursuant to Section 8.1(b)
shall be made and resolved in accordance with the provisions of the Escrow
Agreement.

     (b) Any claim for indemnification pursuant to Section 8.1(c) or (d), shall
be made and resolved in accordance with this Section 8.3. A Person seeking
indemnification shall, prior to the Termination Date, give written notice of
such claim (a "Claim Notice") to the proposed Indemnifying Party. In the case of
Claim Notice seeking indemnification pursuant to Section 8.1(c), the Claim
Notice shall be given by CVC. Each Claim Notice

                                      A-49
<PAGE>   50

shall state the amount of claimed Damages and the basis for such claim. Within
thirty (30) days after delivery of a Claim Notice, the proposed Indemnifying
Party shall provide a written response (the "Response Notice") to the Person who
gave the Claim Notice. If no Response Notice is delivered within such thirty
(30) day period, the proposed Indemnifying Party shall be deemed to have waived
its right to dispute such claim for indemnification. Buyer, on the one hand, and
Seller or CVC, on the other hand, shall use good faith efforts to resolve any
disputed indemnification claim. If the matter is not resolved within fifteen
(15) days of the delivery of the Response Notice, either Party shall have the
right, by delivery of written notice to the other (the "Arbitration Notice"), to
submit the matter to binding arbitration in Stamford, Connecticut. Such matter
shall then be settled by three arbitrators in accordance with the Commercial
Arbitration Rules then in effect of the American Arbitration Association (the
"AAA Rules"). CVC and Buyer shall each designate one arbitrator within fifteen
(15) days of the delivery of the Arbitration Notice. CVC and Buyer shall cause
such designated arbitrators mutually to agree upon and shall designate a third
arbitrator; provided, however, that (i) failing such agreement within forty-five
(45) days of delivery of the Arbitration Notice, the third arbitrator shall be
appointed in accordance with the AAA Rules and (ii) if either CVC or Buyer fails
to timely designate an arbitrator, the dispute shall be resolved by the one
arbitrator timely designated. CVC and Buyer shall pay the fees and expenses of
their respectively designated arbitrators and shall bear equally the fees and
expenses of the third arbitrator. CVC and Buyer shall cause the arbitrators to
decide the matter to be arbitrated pursuant hereto within sixty (60) days after
the appointment of the last arbitrator. The arbitrators' decision shall relate
solely to whether the proposed Indemnified Party is entitled to receive the
claimed Damages (or a portion thereof) pursuant to the applicable terms of this
Agreement. The final decision of the majority of the arbitrators shall be
furnished to Seller or CVC, as applicable, and Buyer in writing and shall
constitute a conclusive, final and nonappealable determination of the issue in
question, binding upon Seller or CVC, as applicable, Buyer and all Seller
Stockholders, as applicable, and their successors and assigns. Such decision may
be used in a court of law only for the purpose of seeking enforcement of the
arbitrators' award.

     (c) The Indemnified Party shall give prompt written notification to the
Indemnifying Party of the commencement of any action, suit or proceeding
relating to a third party claim for which indemnification pursuant to this
Section 8 may be sought. Within twenty (20) Business Days after delivery of such
notification, the Indemnifying Party (which for purposes of this Section 8.3(c)
shall mean Seller or, if the merger has occurred, CVC, as agent for the Seller
Stockholders, in the case of a claim pursuant to Section 8.1(c)) may, upon
written notice thereof to the Indemnified Party, assume control of the defense
of such action, suit or proceeding with counsel reasonably satisfactory to the
Indemnified Party, provided the Indemnifying Party acknowledges in writing to
the Indemnified Party that any Damages that may be assessed against the
Indemnified Party in connection with such action, suit or proceeding constitute
Damages for which the Indemnified Party shall be entitled to indemnification
pursuant to this Section 8. If the Indemnifying Party does not so assume control
of such defense, the Indemnified Party shall control such defense. The Person
not controlling such defense may participate therein at its own expense. The
Person controlling such defense shall keep the other Person (i.e., the
Indemnified Party or the Indemnifying Party, as the case may be) advised of the
status of such action, suit or proceeding and the defense thereof and shall
consider in good faith recommendations made by the other Party with respect
thereto. The Indemnified Party shall not agree to any settlement of such action,
suit or proceeding without the prior written consent of the Indemnifying Party,
which shall not be unreasonably withheld. The Indemnifying Party

                                      A-50
<PAGE>   51

shall not agree to any settlement of such action, suit or proceeding without the
prior written consent of the Indemnified Party, which consent shall not be
unreasonably withheld.

     9.1  Termination of Agreement.

     (a) Buyer and Seller may terminate this Agreement by mutual written consent
at any time prior to the Effective Time.

     (b) Either Buyer or Seller may terminate this Agreement by giving written
notice to the other Party at any time prior to the Effective Time, if the
Closing has not occurred on or before July 31, 1999 by reason of the failure of
any condition precedent under Section 7.1, 7.2 or 7.3 hereof, unless the failure
of the Closing to occur by such date shall be due to the failure of the Party
seeking to terminate this Agreement to perform or observe the covenants and
agreements of such Party set forth herein.

     (c) Either Buyer or Seller may terminate this Agreement by giving written
notice to the other Party at any time prior to the Effective Time if any other

contained in this Agreement, which breach has not been cured within ten (10)
Business Days of receiving notice thereof from the other Party or which breach,
by its nature, cannot be cured prior to July 31, 1999, provided, however, that a
Party may not terminate this Agreement pursuant to this Section 9.1(c) if such
Party is then in breach of any material representation, warranty, covenant or
agreement contained in this Agreement.

     (d) Buyer may terminate this Agreement at any time after Buyer Stockholder
Approval is obtained if (i) Seller Stockholder Approval has not been obtained as
of the effective date of such termination and (ii) each other condition
precedent under Section 7.1 and 7.3 has been, or it is probable will be,
satisfied on or before July 31, 1999.

     9.2  Effect of Termination.  In the event of termination of this Agreement
by either Buyer or Seller as provided in Section 9.1, all rights and obligations
of the Parties hereunder will terminate without any liability of any Party to
any other Party, except (i) Sections 6.6(d) and 9.2 and the liability to pay the
Termination Fee in accordance with Section 9.3, if applicable, will survive any
termination of this Agreement and (ii) notwithstanding anything to the contrary
contained in this Agreement, any termination of this Agreement will not relieve
or release any Party from any liability or damages arising out of its breach of
any provision of this Agreement.

     9.3  Termination Fee.

     (a) If Buyer terminates this Agreement either

          (i) pursuant to Section 9.1(c) after the deadline for Seller
     Stockholder Approval specified in Section 6.2(d), if either Seller or CVC
     materially breached its covenant to use its best efforts to obtain Seller
     Stockholder Approval and as of the effective date of such termination
     Seller Stockholder Approval has not been obtained, or

          (ii) pursuant to Section 9.1(d),

Seller shall, within three (3) Business Days after the effectiveness of such
termination, pay to Buyer the Termination Fee in immediately available funds.

     (b) If Seller terminates this Agreement because of the failure to obtain
Seller Stockholder Approval on or before July 31, 1999, Seller shall, prior to
and as a

                                      A-51
<PAGE>   52

precondition of the effectiveness of such termination, pay to Buyer the
Termination Fee in immediately available funds.

     (c) The "Termination Fee" shall be equal to Five Million Dollars
($5,000,000).

     SECTION 10.  Miscellaneous.

     10.1  Representations and Survival.  The Parties make no other

Effective Time.

     10.2  No Third Party Beneficiaries.  This Agreement shall not confer any

     10.3  Entire Agreement.  This Agreement (including the Schedules) and other

     10.5  Counterparts and Delivery.  This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original but all of which

     10.7  Governing Law.  This Agreement shall be governed by and construed in
accordance with the domestic laws of the State of Connecticut without giving
effect to any choice or conflict of law provision or rule (whether of the State
of Connecticut or any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Connecticut.

     10.8  Consent to Jurisdiction.  EACH PARTY HEREBY IRREVOCABLY SUBMITS TO
THE EXCLUSIVE JURISDICTION OF THE FEDERAL AND STATE COURTS SITTING IN THE STATE
OF CONNECTICUT IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT, THE AGENCY AGREEMENT, THE ESCROW AGREEMENT, THE REGISTRATION RIGHTS
AGREEMENT, THE SELLER AFFILIATE AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY
ANY OF THE FOREGOING. EACH PARTY HEREBY IRREVOCABLY AGREES, ON BEHALF OF ITSELF
AND ON BEHALF OF SUCH PARTY'S SUCCESSORS AND PERMITTED ASSIGNS, THAT ALL CLAIMS
IN RESPECT OF SUCH ACTION OR PROCEEDING SHALL BE HEARD AND DETERMINED IN ANY
SUCH

                                      A-53
<PAGE>   54

     10.9  Waiver of Jury Trial.  EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT
THEY MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, ARISING

AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY ANY OF THE FOREGOING.

     10.10  Amendments and Waivers.  The Parties may mutually amend any
provision of this Agreement at any time prior to the Effective Time with the
prior authorization of their respective boards of directors. No amendment or
other modification of any provision of this Agreement and no waiver of any
provision hereof or any right or benefit hereunder shall be valid unless the
same shall be in writing and signed by each of the Parties. No waiver by any
Party of any default, misrepresentation, or breach of warranty or covenant
hereunder, whether intentional or not, shall be deemed to extend to any prior or
subsequent default, misrepresentation, or breach of warranty or covenant
hereunder or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence.

     10.11  Construction.  The Parties 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 of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context otherwise requires. The
word "including" shall mean including without limitation. The terms "herein",
"hereunder", and terms of similar import refer to this Agreement as a whole and
not to the specific Section or Article in which they are used. The phrase "to
the knowledge" of a Party (and phrases of similar import) shall mean to the
actual knowledge, after reasonable inquiry, of the executive officers of the
Party, as applicable. The Exhibits and Schedule identified in this Agreement are
incorporated herein by reference and made a part hereof. The section headings
contained in this Agreement are inserted for convenience only and shall not
affect in any way the meaning or interpretation of this Agreement.

     10.12  Time is of the Essence; Computation of Time.  Time is of the essence
for each and every provision of this Agreement. Whenever the last day for the

authorized to be closed, the party having such privilege or duty may exercise
such privilege or discharge such duty on the next succeeding day which is a
Business Day.

     10.13  Specific Performance.  Each of the Parties acknowledges that the
rights created hereby are unique and recognizes and affirms that in the event of
a breach of this Agreement irreparable harm would be caused, money damages may
be inadequate and an aggrieved party may have no adequate remedy at law.
Accordingly, each of the Parties agrees that the other Party shall have the
right, in addition to any other rights and remedies existing in its favor at law
or in equity, to enforce its rights and the obligations of the other party
hereunder not only by an action or actions for damages but also by an

                                      A-54
<PAGE>   55

relief (without posting of bond or other security).

                                   APPENDIX B

                                FIRST AMENDMENT

     THIS FIRST AMENDMENT (the "Amendment") is entered into as of July 27, 1999
by and among MacDermid, Incorporated, a Connecticut corporation ("Buyer"), MCD
Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Buyer
("Merger Sub"), PTI, Inc., a Delaware corporation ("Seller"), and Citicorp
Venture Capital, Ltd., a New York corporation ("CVC"), to amend that certain
Plan and Agreement of Merger entered into as of February 18, 1999 (as amended
hereby, the "Merger Agreement"), by and among Buyer, Merger Sub, Seller and CVC.
Buyer, Merger Sub, Seller and CVC are collectively referred to as the "Parties."
Any capitalized term used in this Amendment and not otherwise defined shall have
the meaning ascribed to that term in the Merger Agreement.

     WHEREAS, the Parties desire to extend the date on which the Parties may
terminate the Merger Agreement and to effectuate certain other amendments to the
Merger Agreement in accordance with the terms and conditions set forth herein.

     NOW THEREFORE, in consideration of the mutual agreements set forth herein
and other good and valuable consideration the receipt and sufficiency of which
is hereby acknowledged the Parties agree as follows:

     A. The Merger Agreement is hereby amended, effective as of the date hereof:

          1. By deleting the section reference "2.4(e)" from Section 2.4(h) of
     the Merger Agreement and substituting in the place thereof section
     reference "2.4(e)(ii)."

          2. By adding the following sentence to the end of Section 6.3 to the
     Merger Agreement:

        "The Parties shall use all commercially reasonable efforts, and will
        negotiate in good faith with each other and the FTC, to persuade the FTC
        to approve the Merger in exchange for a settlement with the FTC that is
        consistent in all material respects with the terms set forth on Schedule
        6.3 to this Agreement and containing such other terms and conditions as
        the Parties and the FTC may agree; provided that nothing contained in
        this Agreement shall obligate Buyer to accept a settlement with the FTC
        that imposes any material term or condition that is (i) not expressly
        specified in Schedule 6.3 and (ii) unacceptable to Buyer in Buyer's
        reasonable discretion. Seller shall use all commercially reasonable
        efforts to negotiate and enter into a definitive agreement for the sale
        of the portion of its business described on Schedule 6.3 to a purchaser
        that Buyer and Seller reasonably believe will be acceptable to the FTC,
        which sale may be contingent on the completion of the Merger; and the
        other Parties shall use all commercially reasonable efforts to cooperate
        with Seller in negotiating such sale. A Party will be deemed to have
        satisfied its obligations under this Section to use all commercially
        reasonable efforts to obtain the FTC's approval of the Merger if the
        Party complies with its obligations under the two immediately preceding
        sentences. FTC approval that is conditioned upon a settlement on the
        terms described in Schedule 6.3 hereto shall not by itself be deemed to
        prevent the closing condition specified in Section 7.1(b) from being
        satisfied.

          3. Seller's actions in entering into one or more agreements necessary
     for the sale of the portion of its business consistent with Section 6.3 and
     Schedule 6.3, and all actions by Seller and CVC reasonably necessary in
     connection therewith, shall not, individually or in the aggregate, (i)
     constitute a breach by either Seller or CVC of

                                       B-1
<PAGE>   2

     any of their respective obligations under Section 6.4 or Section 6.8 of the
     Merger Agreement or (ii) prevent the satisfaction of any of the closing
     conditions in Section 7.1, Section 7.2 or Section 7.3 of the Merger
     Agreement.

          4. By deleting in its entirety Section 6.4(e) of the Merger Agreement
     and substituting in the place thereof the following:

             "(e)  not make any single capital expenditure or series of capital
        expenditures during the term of this Agreement outside the Ordinary
        Course without the prior written consent of Buyer, which consent shall
        not be unreasonably withheld, conditioned or delayed."

          5. By deleting in its entirety Section 6.4(i) of the Merger Agreement
     and substituting in the place thereof the following:

             "(i)  deliver to Buyer, within fifteen (15) Business Days of each
        month end from the date hereof through the Closing Date, Seller's
        consolidated unaudited balance sheets, income statements and cash flow
        statements as of and for the immediately preceding month, all consistent
        with the applicable requirements of Section 3.6;

          6. By deleting in its entirety Section 6.4(f) of the Merger Agreement
     and substituting in the place thereof the following:

             "(f)  not enter into any new line of business without Buyer's
        consent, which consent shall not be unreasonably withheld, conditioned
        or delayed and shall be deemed to be given if Buyer does not respond to
        Seller in writing within ten (10) Business Days after receipt of a
        written request from Seller;

          7. By deleting in its entirety Section 6.4(m) of the Merger Agreement
     and substituting in the place thereof the following:

             "(m)  not, without Buyer's consent, which consent shall not be
        unreasonably withheld, conditioned or delayed and shall be deemed to be
        given if Buyer does not respond to Seller in writing within ten (10)
        Business Days after receipt of a written request from Seller, (i)
        acquire by purchasing a substantial equity interest in or a substantial
        portion of the assets of, or by any other manner, any business or any
        corporation, partnership, joint venture, association or other business
        organization or division thereof (or any interest therein), or form any
        subsidiary or (ii) solicit or negotiate any Acquisition Proposal with
        respect to any other Person; provided, however, that Buyer shall have no
        obligation whatsoever to consent to any action by Seller or CVC
        regarding an Acquisition Proposal with respect to which Seller is the
        target company and which is not permitted under Section 6.8 of this
        Agreement;

          8. By deleting all references to the date "July 31, 1999" from Section
     9 of the Merger Agreement and substituting in the place thereof the date
     "September 30, 1999."

          9. By correcting Seller's facsimile number by replacing the number
     "508-439-2105" from Section 10.6 of the Merger Agreement and substituting
     in the place thereof the facsimile number "978-439-2105."

     Agreement:

                                                                       EXECUTION

                                 THIRD AMENDMENT

     THIS THIRD AMENDMENT (the "Amendment") is entered into as of October __,
1999 by and among MacDermid, Incorporated, a Connecticut corporation ("Buyer"),
MCD Acquisition Corp., a Delaware corporation and wholly owned subsidiary of
Buyer ("Merger Sub"), PTI, Inc., a Delaware corporation ("Seller"), and Citicorp
Venture Capital, Ltd., a New York corporation ("CVC"), to amend that certain
Plan and Agreement of Merger entered into as of February 18, 1999 and amended by
the First Amendment thereto (the "First Amendment") dated as of July 27, 1999
and the Second Amendment thereto (the "Second Amendment") dated as of September
13, 1999 (as further amended hereby, the "Merger Agreement"), by and among
Buyer, Merger Sub, Seller and CVC. Buyer, Merger Sub, Seller and CVC are
collectively referred to as the "Parties." Any capitalized term used in this
Amendment and not otherwise defined shall have the meaning ascribed to that term
in the Merger Agreement.

     WHEREAS, the Parties desire to amend the Merger Agreement to, among other
things, adjust the number of Buyer Shares issuable in connection with the Merger
and to extend the date on which the Parties may terminate the Merger Agreement;

     NOW THEREFORE, in consideration of the mutual agreements set forth herein
and other good and valuable consideration the receipt and sufficiency of which
is hereby acknowledged the Parties agree as follows:

     A.   The Merger Agreement is hereby amended, effective as of the date
hereof:

          1.   By deleting Section 2.4(e) of the Merger Agreement in its
entirety and substituting in the place thereof the following:

          (e)  Conversion of Seller Shares. Subject to the provisions of Section
          2.4(h), at and as of the Effective Time, (i) each holder of Seller
          Preferred Shares then outstanding shall by virtue of the Merger be
          entitled to receive that number of Buyer Shares, rounded to the
          nearest thousandth, equal to the quotient obtained by dividing (X) the
          aggregate liquidation value of the Preferred Shares held by such
          holder plus any and all accumulated and unpaid dividends thereon to
          but not including the Effective Time by (Y) the Current Market Price
          as of the Closing Date (the Buyer Shares delivered pursuant to this
          Section 2.4(e)(i) to all holders of Seller Preferred Shares being
          collectively referred to as the "Preferred Exchange Shares"); and (ii)
          each holder of Seller Common Shares then outstanding, other than any
          holder of Dissenting Shares, shall by virtue of the Merger be entitled
          to receive that number of Buyer Shares, rounded to the nearest
          thousandth, which is equal to the product of (X) the Seller Common
          Ratio applicable to such holder of Seller Common Shares multiplied by
          (Y) Seven Million (7,000,000) minus the aggregate number of the
          Preferred Exchange Shares. After the Closing, there shall be no
          transfers on the stock transfer books of Seller Shares which were
          issued and

                                                                       EXECUTION


               outstanding at the Effective Time and converted pursuant to the
               provisions of this Section 2.4(e). After the Effective Time,
               holders of certificates of Seller Shares shall cease to be, and
               shall have no rights as, stockholders of Seller, other than to
               receive Buyer Shares into which such Seller Shares have been
               converted and, if applicable, fractional share payments pursuant
               to the provisions hereof. Schedule 2.4(e) to this Agreement
               illustrates the distribution pursuant to this Agreement of the
               Buyer Shares and the Buyer Warrants (including the Escrow Shares
               and the Escrow Warrant) among, respectively, the Seller
               Stockholders and holder of the CMP Warrant (which is the only
               option, warrant or similar right to acquire Seller Shares that is
               outstanding as of the date of this Agreement), assuming solely
               for purposes of that presentation that (i) there are no
               Dissenting Shares, (ii) there are no accrued and unpaid dividends
               on the Seller Preferred Shares as of the Closing Date, and (iii)
               the Current Market Price as of the Closing Date is equal to
               $33.375.

          2.   By deleting Schedule 2.4(e) attached to the Merger Agreement in
its entirety and substituting in the place thereof the Schedule 2.4(e) attached
hereto.

          3.   By deleting Section 2.4(h) of the Merger Agreement in its
entirety and substituting in the place thereof the following:

               (h)   Escrow Shares. At the Closing, CVC and the Escrow Agent
               shall enter into the Escrow Agreement, which Escrow Agreement is
               intended to serve as an adjustment to the aggregate amount of
               consideration payable to the holders of Seller Common Shares and
               the CMP Warrant in connection with the Merger. At the Closing,
               there shall be withheld from each holder of Seller Common Shares
               a number of Buyer Shares (collectively, the "Escrow Shares")
               equal to the product, rounded to the nearest whole share, of (X)
               the number of Buyer Shares such holder would have otherwise
               received pursuant to Section 2.4(e) multiplied by (Y) the Escrow
               Ratio. The "Escrow Ratio" shall be the quotient obtained by
               dividing (X) One Hundred Twenty-Seven Thousand (127,000) by (Y)
               the arithmetic difference between Seven Million (7,000,000) and
               the aggregate number of the Preferred Exchange Shares. At the
               Closing, Buyer shall deposit with the Escrow Agent one or more
               stock certificates representing the Escrow Shares.

          4.   By deleting Section 2.5(a) of the Merger Agreement in its
entirety and substituting in the place thereof the following:


               (a)   Warrant Shares. As used in this Agreement, the term
               "Warrant Shares" means that number, rounded up to the nearest
               whole integer, which is equal to the product of (X) the Seller
               Common Ratio applicable to the CMP Warrant, treating

               CMP as a holder of Seller Common Shares, multiplied by (Y) Seven
               Million (7,000,000) minus the aggregate number of the Preferred
               Exchange Shares.

          5.   By deleting Section 7.2(g) of the Merger Agreement in its
entirety and substituting in the place thereof the following:

               (g)   The total number of Buyer Shares that potentially may not
               be issued in the Merger as a consequence of one or more Seller
               Stockholders having the right, as of the Closing, to exercise
               dissenter's rights under the DGCL shall not exceed Three Hundred
               Eighty-Five Thousand (350,000).

          6.   By deleting all references to the date "October 29, 1999" from
Section 9 of the Merger Agreement and substituting in the place thereof the date
"December 15, 1999."

          B.   Buyer and Seller shall use all commercially reasonable efforts to
(a) prepare a revised Joint Proxy Statement-Prospectus or a supplement to the
Joint Proxy Statement-Prospectus dated August 30, 1999, as Buyer with the advice
of counsel shall determine (which documents are collectively referred to as the
"Revised Proxy Statement") and (b) file the Revised Proxy Statement in one or
more post-effective amendments (collectively, the "Post-Effective Amendment") to
the S-4 Registration Statement (No. 333-86129) and have the Post-Effective
Amendment declared effective under the Securities Act as promptly as practicable
after the date of this Amendment. All references in the Merger Agreement to the
"Joint Proxy Statement-Prospectus" and the "S-4 Registration Statement" shall
include the "Revised Proxy Statement" and "Post-Effective Amendment,"
respectively, unless the context otherwise requires. Seller and, if required
pursuant to the NYSE Rule, Buyer shall cause the Revised Proxy Statement to be
mailed to their respective stockholders as promptly as practicable after the
Post-Effective Amendment is declared effective under the Securities Act. All
references in the Merger Agreement to "Seller Stockholder Approval" shall mean
the affirmative vote, in favor of a proposal to approve the Merger Agreement as
amended by this Amendment, at a meeting or by written consent after the
effective date of the Post-Effective Amendment, of the holders of a majority of
each class of Seller Voting Shares entitled to vote thereon in accordance with
the certificate of incorporation and bylaws of Seller and Section 251(c) of the
DGCL. To the extent Buyer is required pursuant to the NYSE Rule to resolicit
Buyer Stockholder Approval, all references in the Merger Agreement to Buyer
Stockholder Approval shall mean the affirmative vote, in favor of a proposal to
approve the Merger Agreement as amended by this Amendment, at a meeting after
the effective date of the Post-Effective Amendment, of the holders of a majority
of the outstanding shares of Buyer Common Stock in accordance with the
certificate of incorporation and bylaws of Buyer and Section 251(c) of the DGCL.

     C.   Except as expressly provided by this Amendment, the First Amendment

Agreement, Buyer will deliver to the Escrow Agent the Closing Date (i) a

referred to herein as the "Escrow Fund." The Escrow Fund and each Escrow Account
shall be held as a separate fund and shall not be subject to any lien,
attachment, trustee process or any other judicial process of any creditor of any

accordance with the provisions of this Agreement. In order to facilitate the

Warrant (or an interest therein) or any Primary Escrow Securities purchasable
upon the exercise of the Escrow Warrant, Buyer shall deliver a replacement
Escrow Warrant to the Escrow Agent promptly after receipt of a written request

each Escrow Account Beneficiary. Schedule 1-B attached hereto specifies (i) the
percentage (each, a "Designated Percentage") of the total Escrow Fund which each
such Escrow Account shall constitute as of the Closing Date and (ii) the
specific assets (e.g., Escrow Shares or Escrow Warrant) that comprise each such
Escrow Account as of the Closing Date. The Escrow Agent shall promptly amend
Schedule 1-B to reflect any change in the assets comprising an Escrow Account;
provided, however, that the Designated Percentages of the Escrow Accounts shall

Escrow Agent is an Acceptable Bank; or (e) any open-end or closed-end management
type investment company or investment trust registered under the Investment

instructions, the Escrow Agent shall invest any cash in a State Street Money
Market account.

     The Escrow Agent shall not be responsible or liable for any loss accruing
from any investment made in accordance herewith. All earnings received from the
investment of property in an Escrow Account shall be credited to, and shall

hereunder.

information, written or otherwise, received from an issuer or other person with
respect to the assets in the Escrow Fund, including but not limited to, proxy
material, tenders, options, the pendency of calls and maturities and expiration

Securities pursuant to the Securities Act of 1933, as amended, at any time and
from time to time during the term of this Escrow Agreement, each Escrow Account
Beneficiary may direct in writing the Escrow Agent to sell for cash any or all

Escrow Account Beneficiary's Escrow Account. The Escrow Agent shall have no
responsibility for the adequacy of sale proceeds, compliance with securities
laws or otherwise in connection with any such sale Each Escrow Account

individual Escrow Account may be assigned or transferred, other than by
operation of law, provided that CMP may assign one or more interests in its
Escrow Account to any one or more of its partners. Notice of any such assignment
or transfer shall be given to the Escrow Agent and Buyer, and no such assignment
or transfer shall be valid until such notice is given. Upon receipt of written
notice substantially in the form of Exhibit B attached hereto that a total or
partial transfer or assignment of an Escrow Account has been made, the Escrow
Agent shall promptly amend Schedules 1-A and 1-B to reflect such transfer or
assignment and deliver such amended Schedules 1-A and 1-B to Buyer, CVC, the

with the reports required by Section 4.2 above. Escrow Agent shall have no duty
or responsibility for determining that an assignment or transfer is permissible

          5.5  CVC and Management Representative Representations and Succession.

               (a)  Each of CVC and the Management Representative represents and
     warrants to the Escrow Agent that it or he has irrevocable right, power and
     authority (i) to enter into and perform this Agreement and bind all of the
     Outside Stockholders or Management Stockholders, as the case may be, to its
     terms, (ii) to give and receive



                                      -6-
<PAGE>   7

     directions and notices hereunder; and (iii) to make all determinations that
     may be required or that it or he deems appropriate under this Escrow
     Agreement.

               (b)  Until notified in writing by CVC and the Management
     Representative that it or he has resigned or been removed and a successor
     has been named, the Escrow Agent may act upon the directions, instructions
     and notices of CVC and the Management Representative and, thereafter, upon
     the directions, instructions and notices of any successor named in such
     writing.

     6.   CLAIMS AGAINST ESCROW FUND.

          6.1  Claim Notice. If Buyer has incurred or suffered Damages for which
it is entitled to indemnification under Section 8.1(b) or (d) of the Merger
Agreement, Buyer shall, prior to the Termination Date, give written notice of
such claim (a "Claim Notice") to CVC, the Management Representative and the
Escrow Agent. Each Claim Notice shall state the amount of claimed Damages (the
"Claimed Amount") and the basis for such claim.

          6.2  Response Notice. Within 30 days after delivery of a Claim Notice,
CVC shall provide to Buyer, with a copy to the Escrow Agent and the Management
Representative, a written response (the "Response Notice") in which CVC shall
either: (i) agree that the full Claimed Amount may be released from the Escrow
Fund to Buyer, (ii) agree that part, but not all, of the Claimed Amount (the
"Agreed Amount") may be released from the Escrow Fund to Buyer or (iii) contest
that any of the Escrow Fund may be released to Buyer. CVC may contest the
release of Escrow Fund assets equal to all or a portion or the Claimed Amount
only based upon a good faith belief that all or such portion of the Claimed
Amount does not constitute Damages for which Buyer is entitled to
indemnification under Section 8.1(b) or (d) of the Merger Agreement. If no
Response Notice is delivered to the Escrow Agent by CVC within the 30-day period
from the Escrow Agent's receipt of such Claim Notice, CVC shall be deemed to
have agreed, on behalf of itself and all Escrow Account Beneficiaries, including
the Management Stockholders, that all of the Claimed Amount may be released to
Buyer from the Escrow Fund.

          6.3  Contested Amount. If CVC in the Response Notice contests the
release of Escrow Fund assets equal to all or part of the Claimed Amount (the
"Contested Amount"), Buyer and CVC shall use good faith efforts to resolve the
matter between themselves. If the matter is not resolved within 15 days of the
delivery of the Response Notice contesting the Claimed Amount, either Buyer or
CVC shall have the right, by delivery of written notice to the other (the
"Arbitration Notice"), to submit the matter to binding arbitration in Stamford,
Connecticut. Such matter shall then be settled by three arbitrators in
accordance with the Commercial Arbitration Rules then in effect of the American
Arbitration Association (the "AAA Rules"). CVC and Buyer shall each designate
one arbitrator within 15 days of the delivery of the Arbitration Notice. CVC and
Buyer shall cause such designated arbitrators mutually to agree upon and shall
designate a third arbitrator; provided, however, that (i) failing such agreement
within 45 days of delivery of



                                      -7-
<PAGE>   8

the Arbitration Notice, the third arbitrator shall be appointed in accordance
with the AAA Rules and (ii) if either CVC or Buyer fails to timely designate an
arbitrator, the dispute shall be resolved by the one arbitrator timely
designated. CVC and Buyer shall pay the fees and expenses of their respectively
designated arbitrators and shall bear equally the fees and expenses of the third
arbitrator. CVC and Buyer shall cause the arbitrators to decide the matter to be
arbitrated pursuant hereto within 60 days after the appointment of the last
arbitrator. The arbitrators' decision shall relate solely to whether Buyer is
entitled to receive the Contested Amount (or a portion thereof) pursuant to the
applicable terms of the Merger Agreement and this Agreement. The final decision
of the majority of the arbitrators shall be furnished to CVC, the Management
Representative, Buyer and the Escrow Agent in writing and shall constitute a
conclusive, final and nonappealable determination of the issue in question,
binding upon CVC, the Management Representative, Buyer, the Escrow Agent and all
Escrow Account Beneficiaries. Such decision may be used in a court of law only
for the purpose of seeking enforcement of the arbitrators' award. After delivery
of a Response Notice that the Claimed Amount is contested by CVC, the Escrow
Agent shall continue to hold in the Escrow Fund an amount of Escrow Fund assets
sufficient to cover the Contested Amount (or such lesser amount as is then
available in the Escrow Fund), notwithstanding the occurrence of the Termination
Date, until (i) delivery of a copy of a settlement agreement executed by Buyer
and CVC setting forth instructions to the Escrow Agent as to the release of
Escrow Fund, if any, that shall be made with respect to the Contested Amount or
(ii) delivery of a copy of the final award of the majority of the arbitrators
setting forth instructions to the Escrow Agent as to the amount of the Escrow
Fund, if any, that shall be released with respect to the Contested Amount. The
Escrow Agent shall promptly thereafter release such Escrow Fund assets in
accordance with Section 6.4 of this Agreement.

          6.4  Release of Escrow Fund to Buyer. If (i) pursuant to Section 6.2
CVC agrees (or is deemed to have agreed) that Escrow Fund assets having a value
equal to all of the Claimed Amount may be released from the Escrow Fund to Buyer
or (ii) the Escrow Agent is instructed pursuant to Section 6.3 to release Escrow
Fund assets to Buyer, the Escrow Agent shall promptly thereafter transfer,
deliver and assign to Buyer such an amount of assets from the Escrow Fund equal
to (X) in the case of clause (i) of this sentence, the amount of the Escrow Fund
assets that CVC has agreed (or is deemed to have agreed) to allow the Escrow
Agent to release (or such lesser amount of assets as then comprises the entire
Escrow Fund) or (Y) in the case of clause (ii) of this sentence, the amount of
the Escrow Fund assets that the Escrow Agent has been directed to release (or
such lesser amount of assets as then comprises the entire Escrow Fund), in each
case pro rata from each Escrow Account in accordance with the Designated
Percentages. For purpose of calculating the amount of Escrow Fund assets to be
released, Escrow Securities shall be valued at the Escrow Value. If less than
all of the Escrow Fund assets in an Escrow Account will be released to Buyer
pursuant to this Section 6.4 such assets shall be released in the following
order: (i) first, Primary Escrow Securities in such amounts as the Escrow
Account Beneficiary may direct in writing and (ii) second (to the extent that
assets in addition to Escrow Securities must be released in order to give effect
to the provisions hereof), Secondary Escrow Securities, cash or cash equivalents
or other property constituting assets of each Escrow Account or any combination



                                      -8-
<PAGE>   9

thereof per the written instructions of each Escrow Account Beneficiary). If the
Escrow Agent does not receive such instruction from an Escrow Account
Beneficiary at least two (2) business days prior to an anticipated release date,
Buyer shall so instruct the Escrow Agent. Under no circumstances shall the terms
of this Escrow Agreement require the Escrow Agent to release or distribute all
or any portion of the Escrow Fund sooner than two (2) Business Days after the
Escrow Agent has received the requisite notices or paperwork in good form, or
passage of the applicable claims period or release date, as the case may be.

          6.5  Limitations on Escrow Account Beneficiary Liability.
Notwithstanding anything contained in this Agreement to the contrary, if the
Escrow Value of the Escrow Fund assets in an Escrow Account is insufficient to
satisfy the indemnification obligations to the Buyer with respect thereto, none
of CVC, the Management Representative, the Escrow Account Beneficiary of that
Escrow Account or any other Escrow Account Beneficiary shall be liable hereunder
for such deficiency.

     7.   RELEASE OF ESCROW FUND UPON TERMINATION DATE. Promptly after the
Termination Date, the Escrow Agent shall distribute to the Escrow Account
Beneficiaries, all of the assets constituting each such Escrow Account
Beneficiary's Escrow Account after the payment of such Escrow Account
Beneficiary's share of the fees and expenses of the Escrow Agent.
Notwithstanding the immediately preceding sentence, if Buyer has previously
given a Claim Notice which has not then been resolved in accordance with Section
6, the Escrow Agent shall retain in the Escrow Fund after the Termination Date
an amount of assets from the Escrow Fund equal to the Claimed Amount which has
not then been resolved, which amount shall be retained pro rata from each Escrow
Account in accordance with the Designated Percentages. For purpose of
calculating the amount of Escrow Fund assets to be distributed pursuant to this
Section 7, Escrow Securities shall be valued at the Escrow Value. If less than
all of the Escrow Fund assets in an Escrow Account will be released to an Escrow
Account Beneficiary pursuant to this Section 7, such assets shall be released in
the following order: (i) first, Secondary Escrow Securities, cash or cash
equivalents, or other property (other than Primary Escrow Securities) in such
amounts as the Escrow Account Beneficiary may direct in writing and (ii) second
(to the extent that additional assets from an Escrow Account must be released in
order to give effect to the provisions hereof), Primary Escrow Securities in
such amounts as the Escrow Account Beneficiary may direct in writing. If the
Escrow Agent does not receive such instruction from an Escrow Account
Beneficiary, Buyer shall so instruct the Escrow Agent.

     8.   FEES AND EXPENSES. The fees and expenses of the Escrow Agent
(including reasonable attorneys' fees and expenses) for the preparation of this
agreement and the services to be rendered by the Escrow Agent hereunder in
accordance with the attached fee schedule (which may be subject to change
hereafter on an annual basis) shall be payable out of the Escrow Account pro
rata in accordance with the Designated Percentages of the Escrow Account
Beneficiaries. To the extent there is insufficient cash in an Escrow Account to
pay the fees and expenses of the Escrow Agent in full on a timely basis, Buyer
shall advance such funds to the Escrow Agent,



                                      -9-
<PAGE>   10

which amounts shall be reimbursed in cash or Escrow Securities prior to any
release of Escrow Fund assets to the respective Escrow Account Beneficiary,
provided, however, that if there are insufficient assets in an Escrow Account to
repay in full any such advance, Buyer shall not be entitled to recover the
deficiency from any other Escrow Account or from any other Person.

     9.   LIMITATION OF ESCROW AGENT'S LIABILITY.

          9.1  Duties and Responsibilities. (a) The Escrow Agent may act on any
instrument or other writing reasonably believed by it to be genuine and to have
been signed or presented by the proper person and shall have no responsibility
for the accuracy thereof. The Escrow Agent shall incur no liability with respect
to any action taken or suffered by it in reliance upon any notice, direction,
instruction (including without limitation, wire transfer instructions, whether
incorporated herein or provided in a separate written instruction), consent,
statement or other documents believed by it to be genuine and duly authorized,
nor for other action on inaction except its own willful misconduct or gross
negligence. The Escrow Agent is not charged with any knowledge of, or any duties
or responsibilities in connection with, any other documents and agreements
(including without limitation the Merger Agreement or Agency Agreement), and
shall not be responsible for determining or compelling compliance therewith, and
shall not otherwise be bound thereby. The Escrow Agent's duties and
responsibilities shall be entirely administrative and not discretionary and
determined only with reference to this Escrow Agreement and applicable laws. The
Escrow Agent shall not be responsible for the validity or sufficiency of this
Agreement. In all questions arising under the Escrow Agreement, the Escrow Agent
may rely on the advice of counsel (provided such counsel is not counsel to any
other party to this Agreement) including in-house counsel, and for anything
done, omitted or suffered in good faith by the Escrow Agent based on such advice
the Escrow Agent shall not be liable to anyone. The Escrow Agent shall not be
required to take any action hereunder involving any expense or liability unless
the payment of such expense or liability is made or provided for in a manner
reasonably satisfactory to it. The Escrow Agent shall be obligated only for the
performance of such duties as are expressly and specifically set forth in this
Escrow Agreement on its part to be performed, each of which is ministerial (and
shall not be construed to be fiduciary) in nature, and no implied duties or
obligations of any kind shall be read into this Agreement against or on the part
of the Escrow Agent. In no event shall the Escrow Agent be liable for indirect,
punitive, special or consequential damage or loss (including but not limited to
lost profits) whatsoever, even if the Escrow Agent has been informed of the
likelihood of such loss or damage and regardless of the form of action.

     (b)  The Escrow Agent shall have no more or less responsibility or
liability on account of any action or omission of any book-entry depository,
securities intermediary or other subescrow agent employed by the Escrow Agent
than any such book-entry depository, securities intermediary or other subescrow
agent has to the Escrow Agent, except to the extent that such action or omission
of any book-entry depository, securities intermediary or other subescrow agent
was

caused by the Escrow Agent's own gross negligence, bad faith or wilful
misconduct in breach of this Agreement.

          9.2  Indemnification. The Buyer, on the one hand, and the Escrow
Account Beneficiaries, on the other hand, hereby agree, severally and jointly,
to indemnify the Escrow Agent for, and to hold it harmless against, any loss,
liability or expense (including reasonable attorneys' fees and other costs and
expenses of defending or preparing to defend any claim of liability) incurred
without gross negligence or willful misconduct on the part of Escrow Agent
arising out of or in connection with its carrying out of its duties hereunder.
Without altering or limiting the joint and several liability of the parties
hereunder, as between themselves the Buyer, on the one hand, and the Escrow
Account Beneficiaries, on the other hand, shall be liable for half of any
indemnification amount due hereunder. The amount payable by the Escrow Account
Beneficiaries pursuant to this Section 9.2 shall be allocated among the Escrow
Accounts pro rata in accordance with the Designated Percentages and shall be
paid as an expense in accordance with Section 8. The foregoing indemnification
and agreement to hold harmless shall survive the termination of this Escrow
Agreement and the resignation of the Escrow Agent.

          9.3  Tax-Related Terms.

               (a)  Tax Reporting. The parties hereto agree that, for tax
     reporting purposes, all interest or other income earned from the investment
     of the Escrow Funds in any tax year shall (i) to the extent such interest
     or other income is distributed by the Escrow Agent to any person or entity
     pursuant to the terms of this Agreement during such tax year, be allocated
     to such person or entity, and (ii) otherwise shall be allocated to the
     applicable Escrow Account Beneficiary.

               (b)  Certification of Tax Identification Number. Each of the
     parties hereto agree to, and shall cause each Escrow Account Beneficiary
     to, provide the Escrow Agent with a certified tax identification number by
     signing and returning a Form W-9 (or Form W-8, in case of non-U.S. persons)
     to the Escrow Agent prior to the date on which any income earned on the
     investment of the Escrow Fund is credited to the appropriate Escrow
     Account. The parties hereto understand that, in the event their tax
     identification numbers are not certified to the Escrow Agent, the Internal
     Revenue Code, as amended from time to time, may require withholding of a
     portion of any interest or other income earned on the investment of the
     Escrow Fund.

               (c)  Tax Indemnification. Each of the Buyer and the Escrow
     Account Beneficiaries agrees, jointly and severally, (i) to assume any and
     all obligations imposed now or hereafter by any applicable tax law with
     respect to any payment or distribution of the Escrow Funds or performance
     of other activities under this Agreement, (ii) to instruct the Escrow Agent
     in writing with respect to the Escrow Agent's responsibility for
     withholding and other taxes, assessments or other governmental charges, and
     to instruct

     the Escrow Agent with respect to any certifications and governmental
     reporting that may be required under any laws or regulations that may be
     applicable in connection with its acting as Escrow Agent under this
     Agreement, and (iii) to indemnify and hold the Escrow Agent harmless from
     any liability or obligation on account of taxes, assessments, additions for
     late payment, interest, penalties, expenses and other governmental charges
     that may be assessed or asserted against the Escrow Agent in connection
     with or relating to any payment made or other activities performed under
     the terms of this Agreement, including without limitation any liability for
     the withholding or deduction of (or the failure to withhold or deduct) the
     same, and any liability for failure to obtain proper certifications or to
     report properly to governmental authorities in connection with this
     Agreement, including costs and expenses (including reasonable legal fees
     and expenses), interest and penalties. The foregoing indemnification and
     agreement to hold harmless shall survive the termination of this Agreement.

     10.  TERMINATION. This Agreement shall terminate upon the later of the
Termination Date or the release by the Escrow Agent of all of the Escrow Fund
assets in accordance with this Agreement.

     11.  NOTICES. All notices, instructions and other communications given

     In addition to the limitations on the Escrow Agent's liability set forth in
