                               SEPTEMBER 30, 1997

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On September 30, 1997, the Registrant, through a wholly owned
subsidiary, acquired 93% of BioWhittaker, Inc. (the "Seller") for $11.625 per
share. The remaining 7% was acquired on October 3, 1997. The total purchase
price was approximately $130.9 million. Sales of the Seller in fiscal 1996
(October 31 year-end) were $51.5 million. The purchase price was determined by
arm's length negotiations between the Seller and the Registrant. There is no
material relationship between the Seller and the Registrant and, to the best
knowledge of the Registrant, there is no material relationship between the
Seller and any of the Registrant's affiliates, directors or officers or any
associates of any of its directors or officers.

         The funds used by the Registrant for the acquisition were supplied from
borrowings under a new $400 million credit facility provided by a group of banks
with Chase Manhattan Bank as administrative agent and First National Bank of
Chicago as documentation agent.

         The Seller was acquired by purchase of the outstanding shares of common
stock, with substantial indemnifications from the Seller. As a result of the
acquisition, the Seller has become a wholly-owned subsidiary of the Registrant.
The Seller develops, produces and sells cell culture products to the
biotechnology and pharmaceutical industries for research and for the rapidly
expanding commercial manufacture of biopharmaceutical products. The Registrant
intends to continue such operations.

         The description contained herein of the acquisition is qualified in its
entirety by reference to the Stock Purchase Agreement, dated August 22, 1997,
between the Registrant, B.W. Acquisition Corporation and BioWhittaker, Inc.,
which is attached hereto as Exhibit 10.7.

ITEM 5. OTHER EVENTS

         The Company entered into a new Loan Agreement ("Credit Agreement") on
September 16, 1997 with The Chase Manhattan Bank, First National Bank of
Chicago, Fleet Bank, National Association, Summit Bank, Wachovia Bank, N.A.,
BHF-Bank AG, Bank of America National Trust and Savings Association, The Bank of
Nova Scotia, Credit Lyonnais NY Branch, First Union National Bank, PNC Bank,
National Association, The Bank of New York, Rabobank Nederland NY Branch,
CoreStates Bank, N.A., Mellon Bank, N.A., The Sakura Bank, Limited, State Street
Bank and Trust Company, Sun Trust Bank, Atlanta, Banca Nazionale del Lavoro
S.p.A. NY Branch, and Istituto Bancario San Paolo di Torino S.p.A. This Credit
Agreement replaces the existing Revolving Credit and Term Loan Agreement ("Loan
Agreement") with First National Bank of Chicago, Summit Bank, Fleet Bank,
National Association, Wachovia Bank, N.A., BHF Bank AG, The First National Bank
of Boston, Chase Manhattan Bank, and National City Bank. The new Credit
Agreement provides for a revolving credit facility in the aggregate principal
amount of $400,000,000.

         The new Credit Agreement permits the Company to choose between various
interest rate options and to specify the portion of the borrowing to be covered
by specific interest rate options. Under the Revolving Credit Agreement, the
interest rate options available to the Company are: (a) U.S. Prime rate or (b)
LIBOR plus the applicable margin (ranging from .225% of 1% to .5% of 1%) or (c)
Competitive Bid at a LIBOR Rate Borrowing or a Fixed Rate Borrowing to be
determined by auction. The applicable margin is adjusted based upon the Funded
Indebtedness to Cash Flow Ratio of Cambrex Corporation. Additionally, the
Company pays a commitment fee of between .15% of 1% to .25% of 1% on the entire
portion of the Revolving Credit facilities.

         On September 18, 1997, $60,000,000 from the Credit Agreement was used
to satisfy the outstanding indebtedness under the Loan Agreement.

Competitive Bid in its capacity as a Bank, it shall submit such Competitive Bid

and from time to time, provided that (i) the Company shall give prior notice of
such termination or reduction to the Administrative Agent (which shall promptly
notify each Bank) specifying the amount and effective date thereof, (ii) each
partial reduction of the Commitments shall be in a minimum amount of $5,000,000
and in an integral multiple of $1,000,000 and shall reduce the Commitments of
all of the Banks proportionately, (iii) no such termination or reduction shall
be permitted with respect to any portion of the Commitments as to which a
request for an Advance pursuant to Section 2.4 is then pending, and (iv) any
such Commitment may not be terminated if any Advances are then outstanding and
may not be reduced below the principal amount of Advances then outstanding under
such Commitment. The Commitments or any portion thereof terminated or reduced
pursuant to this Section 2.2, whether optional or mandatory, may not be
reinstated.

                  (b) For purposes of this Agreement, a Letter of Credit Advance
(i) shall be deemed outstanding in an amount equal to the sum of the maximum
amount available to be drawn under the related Letter of Credit on or after the
date of determination and on or before the stated expiry date thereof plus the
amount of any draws under such Letter of Credit that have not been reimbursed as
provided in Section 3.3 and (ii) shall be deemed outstanding at all times on and
before such stated expiry date or such earlier date on which all amounts
available to be drawn under such Letter of Credit have been fully drawn, and
thereafter until all related reimbursement obligations have been paid pursuant
to Section 3.3. As provided in Section 3.3, upon each payment made by the
Issuing Bank in respect of any draft or other demand for payment under any
Letter of Credit, the amount of any Letter of Credit Advance outstanding
immediately prior to such payment shall be automatically reduced by the amount
of each Revolving Credit Loan deemed advanced in respect of the related
reimbursement obligation of the Company.

                  2.3 Fees. (a) The Company agrees to pay to each Bank a
facility fee on the daily amount of the Commitment of such Bank (whether used or
unused), for the period from the date of this Agreement to but excluding the
Termination Date, at a rate equal to the Applicable Margin; provided that, if
such Bank continues to have a participation interest in any Letter of Credit
Advance after its Commitment terminates, then such facility fee shall continue
to accrue on the daily amount of such Bank's participation in any such Letter of
Credit Advance from and including the date on which its Commitment terminates to
but excluding the date on which such Bank ceases to have a participation
interest in such Letter of Credit Advance. Accrued facility fees shall be
payable quarterly in arrears on the last Business Day of each March, June,
September and December, commencing on the first such Business Day occurring
after the date of this Agreement and on the Termination Date, provided that any
facility fees accruing after the date on which the Commitments terminate shall
be payable on demand.

                  (b) The Company agrees to pay (i) with respect to S/L/Cs, (A)
a fee to the Banks computed at the Applicable Margin then in effect with respect
to Eurocurrency Rate Loans of the maximum amount available to be drawn from time
to time under such S/L/C for the period from




                                Credit Agreement
<PAGE>   25
                                     - 20 -




and including the date of issuance of such S/L/C to and including the stated
expiry date of such S/L/C, which fee shall be paid annually in advance at the
time such S/L/C is issued, and (B) an additional fee to the Issuing Bank for its
own account computed at the rate of 1/4 of 1% per annum of such maximum amount
for such period and (ii) with respect to C/L/Cs, (A) a fee to the Banks computed
at the rate of 1/4 of 1% per annum, which fees shall be paid at each time as any
C/L/C is presented or drawn upon, in whole or in part, and shall be computed
upon the amount of such C/L/C which is presented or drawn upon, in whole or in
part, and (B) an additional fee to the Issuing Bank for its own account computed
at the rate of 1/8 of 1% per annum, which fee shall be computed on the amount
and paid on the date(s) described in clause (ii)(A) above. Such fees are
nonrefundable and the Company shall not be entitled to any rebate of any portion
thereof if such Letter of Credit does not remain outstanding through its stated
expiry date or for any other reason. The Company further agrees to pay to the
Issuing Bank, on demand, such other customary administrative fees, charges and
expenses of the Issuing Bank in respect of the issuance, negotiation,
acceptance, amendment, transfer, expiry and payment of such Letter of Credit or
otherwise payable pursuant to the application and related documentation under
which such Letter of Credit is issued in accordance with a schedule of fees
provided by the Issuing Bank to the Company.

                  (c) The Company agrees to pay to the Administrative Agent an
agency fee for its services as Administrative Agent under this Agreement in such
amounts as may from time to time be agreed upon by the Company and the
Administrative Agent.

                  (d) The Company also agrees to pay to each Bank an extension
fee with respect to each extension of the Termination Date pursuant to Section
2.4(d) in an amount equal to 1/12 of 1% of the amount of the Commitment of such
Bank on the date of such extension, 50% of which fee shall be payable upon the
execution of the relevant extension agreement and the remaining 50% of which
shall be payable on earlier of (x) the first anniversary of the execution of
such extension agreement or (y) the termination of the Commitments.

                  2.4 Disbursement of Revolving Credit Advances. (a)(i) Except
with respect to Swing Line Loans, the Company shall give the Administrative
Agent notice of its request for each Revolving Credit Advance not later than
11:00 a.m. New York City time (A) three Eurocurrency Business Days prior to the
date such Advance is requested to be made if such Advance is to be made as a
Eurocurrency Rate Borrowing, (B) three Business Days prior to the date any
Letter of Credit Advance is requested to be made, and (C) on the Business Day
such Advance is requested to be made in all other cases, which notice shall
specify whether a Eurocurrency Rate Borrowing, a Floating Rate Borrowing, or a
Letter of Credit Advance is requested and, in the case of each requested
Eurocurrency Rate Borrowing, the Eurocurrency Interest Period to be initially
applicable to such Borrowing, and the Permitted Currency in which such Loan is
requested to be denominated and, in the case of each Letter of Credit Advance,
such information as may be necessary for the issuance thereof by the Issuing
Bank. The

                                     - 21 -




Administrative Agent shall promptly provide notice of such requested Revolving
Credit Advance to each Bank.

                  (ii) With respect to Swing Line Loans, the Company shall give
the Administrative Agent notice of its request for each Swing Line Loan not
later than 1:00 p.m. New York City time on the same Business Day any Swing Line
Loan is requested to be made. The Administrative Agent, not later than 12:00
noon New York City time the Business Day next succeeding the day such notice of
a Swing Line Loan is given, shall provide notice of each Swing Line Loan to each
Bank unless such Swing Line Loan is paid in full by the Company prior to the
time such notice is given.

                  (iii) Subject to the terms and conditions of this Agreement,
the proceeds of each such requested Advance shall be made available to the
Company by depositing the proceeds thereof, in the case of any Advance
denominated in Dollars, in immediately available funds, in an account maintained
and designated by the Company at the principal office of the Administrative
Agent and, in all other cases, in an account maintained and designated by the
Company at a bank acceptable to the Administrative Agent in the principal
financial center of the country issuing the Permitted Currency in which such
Loan is denominated or in such other reasonable place specified by the
Administrative Agent. Subject to the terms and conditions of this Agreement, the
Issuing Bank shall, on the date any Letter of Credit Advance is requested to be
made, issue the related Letter of Credit for the account of the Company.
Notwithstanding anything herein to the contrary, the Issuing Bank may decline to
issue any requested Letter of Credit on the basis that the beneficiary, the
purpose of issuance or the terms or the conditions of drawing are unacceptable
to it in its discretion.

                  (b) Each Bank, on the date any Revolving Credit Borrowing in
the form of a Loan (other than a Swing Line Loan) is required to be made, shall
make its pro rata share of such Revolving Credit Borrowing available in
immediately available, freely transferable, cleared funds for disbursement to
the Company pursuant to the terms and conditions of this Agreement, in the case
of any Revolving Credit Borrowing denominated in Dollars, at the principal
office of the Administrative Agent and, in all other cases, to the account of
the Administrative Agent (or any of its affiliates) at its branch or office or
correspondent bank designated for payments in the Permitted Currency in which
such Revolving Credit Borrowing is denominated or in such other reasonable place
specified by the Administrative Agent. Unless the Administrative Agent shall
have received notice from any Bank prior to the date such Borrowing is requested
to be made under this Section 2.4 that such Bank will not make available to the
Administrative Agent such Bank's pro rata portion of such Revolving Credit
Borrowing, the Administrative Agent may assume that such Bank has made such
portion available to the Administrative Agent on the date such Revolving Credit
Borrowing is requested to be made in accordance with this Section 2.4. If and to
the extent such Bank shall not have so made such pro rata portion available to
the Administrative Agent, the Administrative Agent may (but shall not be
obligated to) make such amount available to the Company, and such Bank and the
Company severally agree to pay to the




                                Credit Agreement
<PAGE>   27
                                     - 22 -




Administrative Agent forthwith on demand such amount together with interest
thereon, for each day from the date such amount is made available to the Company
by the Administrative Agent until the date such amount is repaid to the
Administrative Agent, at (i) the rate per annum equal to the interest rate
applicable to such Revolving Credit Borrowing during such period in the case of
the Company and (ii) the rate per annum equal to the Federal Funds Effective
Rate during such period in the case of any Bank. If such Bank shall pay such
amount to the Administrative Agent together with interest, such amount so paid
shall constitute a Loan by such Bank as a part of such Borrowing for purposes of
this Agreement. The failure of any Bank to make its pro rata portion of any such
Borrowing available to the Administrative Agent shall not relieve any other Bank
of its obligations to make available its pro rata portion of such Borrowing on
the date such Borrowing is requested to be made, but no Bank shall be
responsible for failure of any other Bank to make such pro rata portion
available to the Administrative Agent on the date of any such Borrowing.

                  (c) Nothing in this Agreement shall be construed to require or
authorize any Bank to issue any Letter of Credit, it being recognized that the
Issuing Bank has the sole obligation under this Agreement to issue Letters of
Credit on behalf of the Banks, and the Commitment of each Bank with respect to
Letter of Credit Advances is expressly conditioned upon the Issuing Bank's
performance of such obligations. Upon such issuance by the Issuing Bank, each
Bank shall automatically acquire a pro rata risk participation interest in such
Letter of Credit Advance based on its respective Commitment. If the Issuing Bank
shall honor a draft or other demand for payment presented or made under any
Letter of Credit, the Issuing Bank shall provide notice thereof to each Bank on
the date such draft or demand is honored unless the Company shall have satisfied
its reimbursement obligation under Section 3.3 by payment to the Issuing Bank on
such date. Each Bank, on such date, shall make its pro rata share of the amount
paid by the Issuing Bank available in immediately available funds at the
principal office of the Administrative Agent for the account of the Issuing
Bank. If and to the extent such Bank shall not have made any required pro rata
portion available to the Issuing Bank, such Bank and the Company severally agree
to pay to the Issuing Bank forthwith on demand such amount together with
interest thereon, for each day from the date such amount was paid by the Issuing
Bank until such amount is so made available to the Issuing Bank at (i) the per
annum rate equal to the interest rate applicable during such period to the
related Loan disbursed under Section 3.3 in respect of the reimbursement
obligation of the Company in the case of the Company and (ii) the rate per annum
equal to the Federal Funds Effective Rate during such period in the case of any
Bank. If such Bank shall pay such amount to the Issuing Bank together with such
interest, such amount so paid shall constitute a Revolving Credit Loan by such
Bank as part of the Revolving Credit Borrowing disbursed in respect of the
reimbursement obligation of the Company under Section 3.3 for purposes of this
Agreement. The failure of any Bank to make its pro rata portion of any such
amount paid by the Issuing Bank available to the Issuing Bank shall not relieve
any other Bank of its obligation to make available its pro rata portion of such
amount, but no Bank shall be responsible for failure of any other Bank to make
such pro rata portion available to the Issuing Bank.

                  (d) (i) The Banks agree that, subject to the provisions of
this Section 2.4(d), the then existing Termination Date (i.e., September 16,
2002) may be extended for a period of two years beyond such Termination Date
(i.e., September 16, 2004) on the fourth anniversary of the date hereof (i.e.
September 16, 2001) and on such date every two years thereafter (i.e., September
16, 2003, September 16, 2005, etc.). Such extension shall be deemed to have been
requested by the Company unless the Company delivers notice in writing to the
Administrative Agent of its election not to extend the Termination Date not less
than 150 days prior to the date such extension is to be effective. Each of the
Banks agrees to provide notice in writing to the Administrative Agent of its
agreement or refusal to extend such Termination Date not less than 120 days
prior to the date such extension is to be effective; provided, however, that the
failure of any Bank to so communicate its agreement or refusal shall be deemed
to be such Bank's refusal to so extend the Termination Date. The determination
to extend or not to extend the Termination Date shall be given or withheld by
each Bank in its absolute and sole discretion and any such agreement or refusal
once given shall (except as expressly provided in clause (ii) below) be
irrevocable.

                  (ii) If the aggregate Commitments of all of the Banks
consenting to such extension equal or exceed 60% of the total Commitments, the
Termination Date shall be extended as provided in clause (iii) below. If the
aggregate Commitments of all of the Banks consenting to such extension equal
less than 60% of the total Commitments, the Administrative Agent shall notify
each such consenting Bank, and each such Bank shall have five Business Days to
confirm or revoke its agreement to extend the Termination Date.

                  (iii) In the event that one or more Banks agree to extend the
existing Termination Date, (A) the existing Termination Date shall be extended
to the date two years after the existing Termination Date (or, if such date is
not a Business Day, the next preceding Business Day), (B) the Commitment of each
extending Bank shall remain unchanged and (C) additional lenders may be added to
this Agreement in replacement of any non-extending Banks by executing an
Assumption Agreement substantially in the form of Exhibit G hereto, provided
that each of the extending Banks shall have the right of first refusal to accept
a pro rata increase in its Commitment before any additional lender is added
hereto.

                  (iv) On the existing Termination Date (prior to giving effect
to any extension thereof), the Commitment of each non-extending Bank shall
terminate and the Company shall pay in full all amounts owing to such
non-extending Bank hereunder.

                  2.5 Conditions for Effective Date. The obligation of the Banks
to make the first Advance hereunder shall not become effective until the date on
which each of the following conditions is satisfied (or waived in accordance
with Section 8.1):

         other matters relating to the Company or this Agreement or the other

         written opinion (addressed to the Administrative Agent and the Banks
         and dated the Effective Date) of Milbank, Tweed, Hadley & McCloy,
         special New York counsel for Chase, substantially in the form of
         Exhibit E. Chase hereby requests such counsel to deliver such opinion.

                  (d) The Administrative Agent shall have received such
         documents and certificates as the Administrative Agent or its counsel
         may reasonably request relating to the organization, existence and good
         standing of the Company and the Guarantors, the authorization of the

         certificates and all financing statements in connection therewith, and
         the Guaranty duly executed, and, in addition, the Administrative Agent
         shall have received the results of searches, in form and scope and as
         of such dates as are satisfactory to the Administrative Agent, of UCC,
         tax, judgment and all other liens which may have been filed against the

         approvals, authorizations, declarations, registrations or filings, if

         validity or enforceability of this Agreement, any promissory note
         issued hereunder or any of the Support Documents, certified as true and
         correct in full force and effect as of the Effective Date by a duly
         authorized officer of the Company, or if none are required, a
         certificate of such officer to that effect;

                  (h) The Administrative Agent shall have received evidence that
         the principal of and interest on, and all other amounts owing in
         respect of, the Indebtedness (including, without limitation, any
         contingent or other amount payable in respect of letters of credit)
         that is to be repaid on the Effective Date (including, without
         limitation, all Indebtedness under the Existing Credit Agreement) shall
         have been (or shall simultaneously be) paid in full, that any

         Indebtedness shall have been released (or arrangements for such release

                                     - 26 -




                  (i) the representations and warranties contained in Article IV
         and in the Support Documents (including, without limitation, any
         Environmental Certificate) shall be true and correct on and as of the
         date such Advance is made (both before and after such Advance is made)
         as if such representations and warranties were made on and as of such
         date;

                  (ii) no Event of Default and no Default shall exist or shall
         have occurred and be continuing on the date such Advance is made
         (whether before or after such Advance is made); and

                  (iii) in the case of any Letter of Credit Advance, the Company
         shall have delivered to the Issuing Bank an application for the related
         Letter of Credit and other related documentation requested by and
         acceptable to the Issuing Bank appropriately completed and duly
         executed on behalf of the Company.

The Company shall be deemed to have made a representation and warranty to the
Banks at the time of the making of, and the continuation or conversion of, each
Advance to the effects set forth in clauses (i) and (ii) of this Section 2.6.
For purposes of this Section 2.6, the representations and warranties contained
in Section 4.6 shall be deemed made with respect to both the financial
statements referred to therein and the most recent financial statements
delivered pursuant to Section 5.1(d)(ii) and (iii).

                  2.7 Subsequent Elections as to Borrowings. The Company may
elect (a) to continue a Eurocurrency Rate Borrowing, or a portion thereof, as a
Eurocurrency Rate Borrowing or (b) may elect to convert a Eurocurrency Rate
Borrowing, or a portion thereof, to a Floating Rate Borrowing or (c) elect to
convert a Floating Rate Borrowing, or a portion thereof, to a Eurocurrency Rate
Borrowing, or (d) elect to convert a Borrowing denominated in a Permitted
Currency to a Borrowing denominated in another Permitted Currency, in each case
by giving notice thereof to the Administrative Agent not later than 11:00 a.m.
New York City time three Eurocurrency Business Days prior to the date any such
continuation of or conversion to a Eurocurrency Rate Borrowing is to be
effective and not later than 11:00 a.m. New York City time one Business Day
prior to the date such conversion is to be effective in all other cases,
provided that an outstanding Eurocurrency Rate Borrowing may only be converted
on the last day of the then current Eurocurrency Interest Period with respect to
such Borrowing, and provided, further, that a Revolving Credit Loan may not be
converted to a Swing Line Loan or a Competitive Loan. If a continuation of a
Borrowing as, or a conversion of a Borrowing to, a Eurocurrency Rate Borrowing
is requested, such notice shall also specify the Eurocurrency Interest Period to
be applicable thereto upon such continuation or conversion. The Administrative
Agent shall promptly provide notice of such election to the Banks. If the
Company shall not timely deliver such a notice with respect to any outstanding
Eurocurrency Rate Borrowing, the Company shall be deemed to have elected to
convert such Eurocurrency

Rate Borrowing to a Floating Rate Borrowing on the last day of the then current
Eurocurrency Interest Period with respect to such Borrowing.

                  2.8 Limitation of Requests and Elections. Notwithstanding any
other provision of this Agreement to the contrary, if, upon receiving a request
for a Eurocurrency Rate Borrowing pursuant to Section 2.1(c) or 2.4, or a
request for a continuation of a Eurocurrency Rate Borrowing as a Eurocurrency
Rate Borrowing, or a request for a conversion of a Floating Rate Borrowing to a
Eurocurrency Rate Borrowing pursuant to Section 2.7 or a request for a
conversion of a Eurocurrency Rate Borrowing denominated in a Permitted Currency
to a Eurocurrency Rate Borrowing denominated in another Permitted Currency, (i)
in the case of any Eurocurrency Rate Borrowing, deposits in the relevant
Permitted Currency for periods comparable to the Eurocurrency Interest Period
elected by the Company are not available to a Bank in the relevant interbank
market, or (ii) the applicable interest rate will not adequately and fairly
reflect the cost to a Bank of making, funding or maintaining the related
Eurocurrency Rate Borrowing or (iii) by reason of national or international
financial, political or economic conditions or by reason of any applicable law,
treaty, rule or regulation (whether domestic or foreign) now or hereafter in
effect, or the interpretation or administration thereof by any governmental
authority charged with the interpretation or administration thereof, or
compliance by a Bank with any guideline, request or directive of such authority
(whether or not having the force of law), including without limitation exchange
controls, it is impracticable, unlawful or impossible for (A) a Bank to make or
fund the relevant Eurocurrency Rate Borrowing or to continue such Eurocurrency
Rate Borrowing as a Eurocurrency Rate Borrowing or to convert a Floating Rate
Borrowing to a Eurocurrency Rate Borrowing, or (B) the Company to make or a Bank
to receive any payment under this Agreement at the place specified for payment
hereunder or to freely convert any amount paid into Dollars at market rates of
exchange or to transfer any amount paid or so converted to the address of its
principal office specified in Section 8.2, then the Company shall not be
entitled, so long as such circumstances continue, to request and the Banks shall
not be obligated to make (so long as such circumstances exist) a Eurocurrency
Rate Borrowing pursuant to Section 2.1(c) or 2.4 or a continuation of or
conversion to a Eurocurrency Rate Borrowing pursuant to Section 2.7. In the
event that such circumstances no longer exist, the Banks shall again consider
requests for Eurocurrency Rate Borrowings pursuant to Section 2.1(c) or 2.4, and
requests for continuations of and conversions to Eurocurrency Rate Borrowings
pursuant to Section 2.7.

                  2.9 Minimum Amounts; Limitation on Number of Borrowings.
Except for (a) Advances and conversions thereof which exhaust the entire
remaining amount of the Commitments and (b) payments required pursuant Section
3.8, each Borrowing and each continuation or conversion pursuant to Section 2.7
and each prepayment thereof shall be in a minimum amount of, in the case of
Eurocurrency Rate Borrowings, $5,000,000 (or the Optional Currency Equivalent
thereof) and in integral multiples of $1,000,000 (or the Optional Currency
Equivalent thereof), and in the case of Floating Rate Borrowings, $500,000 and
in integral multiples of $100,000, and each Letter of Credit Advance shall be in
a minimum amount of

$100,000. No more than eight Eurocurrency Interest Periods shall be permitted to
exist at any one time with respect to all Borrowings outstanding hereunder from
time to time.

                  2.10 Support and Collateral. To secure the payment when due of
all obligations of the Company under this Agreement to the Banks and the
Administrative Agent, the Company shall execute and deliver, or cause to be
executed and delivered, to the Banks and the Administrative Agent Support
Documents granting the following:

                  (a) guaranties of all Subsidiaries of the Company that are not
Foreign Subsidiaries; and

                  (b) pledges of (i) 66% of the voting capital stock of each
Foreign Subsidiary that is a direct Subsidiary of (x) the Company or (y) a
Subsidiary of the Company which is organized under the laws of the United States
of America or a State thereof and which is not a Subsidiary of a Foreign
Subsidiary (each, a "Pledged Subsidiary") and (ii) 100% of all other stock of
each Pledged Subsidiary.

                      PAYMENTS AND PREPAYMENTS OF ADVANCES

                  3.1 Principal Payments.

                  (a) Unless earlier payment is required under this Agreement,
the Company shall pay (i) to the Administrative Agent (for the account of the
Banks) the entire outstanding principal amount of the Revolving Credit Loans on
the Termination Date and (ii) to the Administrative Agent (for the account of
each Bank making a Competitive Loan) the entire outstanding principal amount of
such Competitive Loan on the last day of the Eurocurrency Interest Period or
Fixed Rate Interest Period applicable to such Competitive Loan.

                  (b) The Company may at any time and from time to time prepay
all or a portion of the Loans, without premium or penalty, provided that (i) the
Company may not prepay any Competitive Loan without the prior consent of the
Bank holding such Competitive Loan, (ii) the Company may not prepay any portion
of any Loan as to which an election of or a conversion to a Eurocurrency Rate
Loan is pending pursuant to Section 2.7, (iii) unless earlier payment is
required under this Agreement, any Eurocurrency Rate Loan may only be prepaid on
the last day of the then current Eurocurrency Interest Period with respect to
such Loan, and (iv) such prepayment shall only be permitted if the Company shall
have given not less than one Business Day's notice thereof to the Administrative
Agent in the case of prepayment of any Floating Rate Loan and ten days' notice
thereof to the Administrative Agent for all other Loans, in each case such
notice specifying the Loan or portion thereof to be so prepaid and shall have
paid to the Banks, together with such prepayment of principal, all accrued
interest to the date of payment on




                                Credit Agreement
<PAGE>   34
                                     - 29 -




such Loan or portion thereof so prepaid and all amounts owing to the Banks under
Section 3.9 in connection with such prepayment. Upon the giving of such notice,
the aggregate principal amount of such Loan or portion thereof so specified in
such notice, together with such accrued interest and other amounts, shall become
due and payable on the specified prepayment date. The Administrative Agent shall
promptly notify the Banks of any such notice of prepayment.

                  (c) During any period in which Revolving Credit Loans
denominated in Optional Currencies are outstanding, on each day that a
Eurocurrency Rate Borrowing, or portion thereof, is continued as a Eurocurrency
Rate Borrowing or any Floating Rate Loan is converted into a Eurocurrency Rate
Borrowing, but not more than once in any rolling seven-day period, the
Administrative Agent shall determine the aggregate outstanding principal amount
of all Advances (for which purpose the outstanding principal amount of all
Revolving Credit Loans made in an Optional Currency shall be deemed to be the
Dollar Equivalent (determined as of the date of such continuation or conversion)
of the amount in such Optional Currency of such Revolving Credit Loan). Upon
making such determination, the Administrative Agent shall promptly notify the
Banks and the Borrower thereof. If, on such date of determination, all Advances
then outstanding under this Agreement exceed the aggregate amount of the
Commitments of the Banks, the Company shall prepay to the Banks on the last day
of such related Eurocurrency Interest Period an amount equal to the amount of
such excess, together with any amounts owing to the Banks under Section 3.9 in
connection therewith.

                  3.2 Interest Payments. The Company shall pay interest to the
Banks on the unpaid principal amount of each Loan, for the period commencing on
the date such Loan is made until such Loan is paid in full, on each Interest
Payment Date and at maturity (whether at stated maturity, by acceleration or
otherwise), and thereafter on demand, at the following rates per annum:

                  (a) during such periods that such Loan is a Floating Rate
Loan, the Floating Rate, and

                  (b) during such periods that such Loan is a Eurocurrency Rate
Loan, the Eurocurrency Rate applicable to such Loan for each related
Eurocurrency Interest Period;

provided that each Fixed Rate Loan shall bear interest at the Fixed Rate for
such Loan. Notwithstanding the foregoing, the Company shall pay interest on
demand at the Overdue Rate on the outstanding principal amount of any Loan and
any other amount payable by the Company hereunder (other than interest) which is
not paid in full when due (whether at stated maturity, by acceleration or
otherwise) for the period commencing on the due date thereof until the same is
paid in full.

                  3.3 Letter of Credit Reimbursement Payments. (a)(i) The
Company agrees to pay to the Administrative Agent (for the account of the
Issuing Bank) on the day on which the

<PAGE>   35
                                     - 30 -




Issuing Bank shall honor a draft or other demand for payment presented or made
under any Letter of Credit, an amount equal to the amount paid by the Issuing
Bank in respect of such draft or other demand under such Letter of Credit and
all expenses paid or incurred by the Issuing Bank related thereto. Unless the
Company shall have made such payment to the Issuing Bank on such day, upon each
such payment by the Issuing Bank, the Banks shall be deemed to have disbursed to
the Company, and the Company shall be deemed to have elected to satisfy its
reimbursement obligation by, a Revolving Credit Loan bearing interest at the
Floating Rate in an amount equal to the amount so paid by the Issuing Bank in
respect of such draft or other demand under such Letter of Credit. The amount of
such Revolving Credit Loan shall be made available by the Banks to the
Administrative Agent (for the benefit of the Issuing Bank) in accordance with
Section 2.4(b). The participation of each Bank in the relevant Letter of Credit
shall be deemed to be reduced by the amount made available by such Bank and, to
the extent of the Revolving Credit Loan so disbursed, the reimbursement
obligation of the Company under this Section 3.3 shall be deemed satisfied.

                  (ii) If for any reason (including without limitation as a
         result of the occurrence of an Event of Default with respect to the
         Company or any of its Subsidiaries pursuant to Section 6.1(h)),
         Floating Rate Loans may not be made by the Banks as described in
         Section 3.3(a)(i), then (A) the Company agrees that each reimbursement
         amount not paid pursuant to the first sentence of Section 3.3(a)(i)
         shall bear interest, payable on demand by the Administrative Agent, at
         the Overdue Rate, and (B) effective on the date each such Floating Rate
         Loan would otherwise have been made, each Bank severally agrees that it
         shall unconditionally and irrevocably, without regard to the occurrence
         of any Default or Event of Default, in lieu of a deemed disbursement of
         Revolving Credit Loans, to the extent of such Bank's Commitment,
         purchase a participating interest in each reimbursement amount. Each
         Bank will immediately transfer to the Administrative Agent, in same day
         funds, the amount of its participation. Each Bank shall share on a pro
         rata basis (calculated by reference to the Commitments) in any interest
         which accrues thereon and in all repayments thereof. If and to the
         extent that any Bank shall not have so made the amount of such
         participating interest available to the Administrative Agent, such Bank
         and the Company agree to pay to the Administrative Agent forthwith on
         demand such amount together with interest thereon, for each day from
         the date of demand by the Administrative Agent until the date such
         amount is paid to the Administrative Agent, at (x) in the case of the
         Company, the Overdue Rate and (y) in the case of such Bank, the Federal
         Funds Effective Rate.

                  (b) The reimbursement obligation of the Company under this
Section 3.3 shall be absolute, unconditional and irrevocable and shall remain in
full force and effect until all obligations of the Company to the Banks
hereunder shall have been satisfied, and such obligations of the Company shall
not be affected, modified or impaired upon the happening of any event, including
without limitation, any of the following, whether or not with notice to, or the
consent of, the Company:

                  (i) any lack of validity or enforceability of any Letter of
         Credit or any documentation relating to any Letter of Credit or to any
         transaction related in any way to such Letter of Credit (the "Letter of
         Credit Documents");

                  (ii) any amendment, modification, waiver or consent, or any
         substitution, exchange or release of or failure to perfect any interest
         in collateral or security, with respect to any of the Letter of Credit
         Documents;

                  (iii) the existence of any claim, setoff, defense or other
         right which the Company may have at any time against any beneficiary or
         any transferee of any Letter of Credit (or any persons or entities for
         whom any such beneficiary or any such transferee may be acting), the
         Issuing Bank, the Administrative Agent or any Bank or any other person
         or entity, whether in connection with any of the Letter of Credit
         Documents, the transactions contemplated herein or therein or any
         unrelated transactions;

                  (iv) any draft or other statement or document presented under
         any Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

                  (v) payment by the Issuing Bank to the beneficiary under any
         Letter of Credit against presentation of documents which do not comply
         with the terms of the Letter of Credit, including failure of any
         documents to bear any reference or adequate reference to such Letter of
         Credit;

                  (vi) any failure, omission, delay or lack on the part of the
         Issuing Bank, any Bank or the Administrative Agent or any party to any
         of the Letter of Credit Documents to enforce, assert or exercise any
         right, power or remedy conferred upon the Issuing Bank, the
         Administrative Agent, any Bank or any such party under this Agreement
         or any of the Letter of Credit Documents, or any other acts or
         omissions on the part of the Issuing Bank, the Administrative Agent,
         any Bank or any such party; or

                  (vii) any other event or circumstance that would, in the
         absence of this clause, result in the release or discharge by operation
         of law or otherwise of the Company from the performance or observance
         of any obligation, covenant or agreement contained in this Section 3.3.

No setoff, counterclaim, reduction or diminution of any obligation or any
defense of any kind or nature which the Company has or may have against the
beneficiary of any Letter of Credit shall be available hereunder to the Company
against the Issuing Bank, the Administrative Agent or any Bank. Nothing in this
Section 3.3 shall limit the liability, if any, of the Company to the Banks
pursuant to Section 8.5.

                  3.4 Payment Method. (a) All payments to be made by the Company
hereunder will be made to the Administrative Agent for the account of the Banks
(including, as applicable, the Swing Line Bank and/or the Issuing Bank) (i) in
the case of principal and interest on any Loan, in the Permitted Currency in
which such Loan is denominated, and (ii) in all other cases, in Dollars, and in
all cases in immediately available, freely transferable, cleared funds not later
than 1:00 p.m. at the place for payment on the date on which such payment shall
be come due (x) in the case of principal and interest on any Loan denominated in
a Permitted Currency other than Dollars, by credit to the account of the
Administrative Agent at its branch or office or correspondent bank designated
for payments in the relevant Permitted Currency or in such other place specified
by the Administrative Agent with respect to such Loan pursuant to Section
2.4(b), and (y) in all other cases to the Administrative Agent at its offices at
270 Park Avenue, New York, New York, except where payments are to be made
directly to the Issuing Bank or the Swing Line Bank or to the Person entitled
thereto under Section 3.7, 3.9 or 8.5. Payments received after 1:00 p.m. at the
place for payment shall be deemed to be payments made prior to 1:00 p.m. at the
place for payment on the next succeeding Business Day. The Company hereby
authorizes the Administrative Agent to charge its account with the
Administrative Agent in order to cause timely payment of amounts due hereunder
to be made (subject to sufficient funds being available in such account for that
purpose).

                  (b) At the time of making each such payment, the Company
shall, subject to the other terms and conditions of this Agreement, specify to
the Administrative Agent that Loan or other obligation of the Company hereunder
to which such payment is to be applied. In the event that the Company fails to
so specify the relevant obligation or if an Event of Default or Default shall
have occurred and be continuing, the Administrative Agent may apply such
payments as it may determine in its sole discretion.

                  (c) On the day such payments are deemed received, the
Administrative Agent shall remit to the Banks their pro rata shares of such
payments in immediately available same day funds, (i) in the case of payments of
principal and interest on any Borrowing denominated in a Permitted Currency
other than Dollars, at an account maintained and designated by each Bank at a
bank in the principal financial center of the country issuing the Permitted
Currency in which such Borrowing is denominated or in such other reasonable
place specified by such Bank and (ii) in all other cases, to the Banks at their
respective address in the United States specified for notices pursuant to
Section 8.2. In the case of payments of principal and interest on any Borrowing,
such pro rata shares shall be determined with respect to each such Bank by the
ratio which the outstanding principal balance of its Loan included in such
Borrowing bears to the outstanding principal balance of the Loans of all the
Banks included in such Borrowing and in the case of fees paid pursuant to
Section 2.3 and other amounts payable hereunder (other than the Administrative
Agent's fees payable pursuant to Section 2.3(c) and amounts payable to any Bank
under Section 2.1(c), 2.3(d), 3.7 or 3.9), such pro rata shares shall be
determined with respect to




                                Credit Agreement
<PAGE>   38
                                     - 33 -




each such Bank by the ratio which the Commitment of such Bank bears to the
Commitments of all the Banks.

                  (d) This Agreement arises in the context of an international
transaction, and the specification of payments in specific currencies at
specific places pursuant to this Agreement is of the essence. Each specified
currency shall be the currency of account and payment under this Agreement as
provided herein. The obligations of the Company hereunder shall not be
discharged by an amount paid in any other currency or at another place, whether
pursuant to a judgment or otherwise, to the extent that the amount so paid, on
prompt conversion into the applicable currency and transfer to the Banks under
normal banking procedure, does not yield the amount of such currency due under
this Agreement. In the event that any payment, whether pursuant to a judgment or
otherwise, upon conversion and transfer, does not result in payment of the
amount of such currency due under this Agreement, the Company shall indemnify
the Banks, as a separate obligation, for such currency deficit.

                  (e) If for purposes of obtaining judgment in any court it
becomes necessary to convert any currency due hereunder into any other currency,
the Company will pay such additional amount, if any, as may be necessary to
ensure that the amount paid in respect of such judgment is the amount in such
other currency which when converted at the Administrative Agent's spot rate of
exchange prevailing on the date of payment would yield the same amount of the
currency due hereunder. Any amount due from the Company under this Section
3.4(e) will be due as a separate debt and shall not be affected by judgment
being obtained for any other sum due under or in respect of this Agreement.

                  3.5 No Setoff or Deduction. All payments of principal and
interest on the Loans and other amounts payable by the Company hereunder shall
be made by the Company without setoff or counterclaim, and free and clear of,
and without deduction or withholding for, or on account of, any present or
future taxes, levies, imposts, duties, fees, assessments, or other charges of
whatever nature, imposed by any governmental authority, or by any department,
agency or other political subdivision or taxing authority.

                  3.6 Payment on Non-Business Day; Payment Computations. Except
as otherwise provided in this Agreement to the contrary, whenever any
installment of principal of, or interest on, any Loan or any other amount due
hereunder becomes due and payable on a day which is not a Business Day, the
maturity thereof shall be extended to the next succeeding Business Day and, in
the case of any installment of principal, interest shall be payable thereon at
the rate per annum determined in accordance with this Agreement during such
extension. All interest, fees and other amounts due under this Agreement shall
be computed on the basis of a year of 360 days, except that interest computed by
reference to the Floating Rate at times when the Floating Rate is based on the
Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in
a leap year), and in each case shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

            3.7 Additional Costs. (a) In the event that any applicable law,
treaty, rule or regulation (whether domestic or foreign) now or hereafter in
effect and whether or not presently applicable to any Bank, the Issuing Bank or
the Administrative Agent, or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by any Bank, the Issuing Bank or the Administrative Agent
with any guideline, request or directive of any such authority (whether or not
having the force of law), shall

            (i) affect the basis of taxation of payments to any Bank, the
      Issuing Bank or the Administrative Agent of any amounts payable by the
      Company under this Agreement (other than taxes imposed on the overall net
      income of the Bank, the Issuing Bank or the Administrative Agent, by the
      jurisdiction, or by any political subdivision or taxing authority of any
      such jurisdiction, in which any Bank, the Issuing Bank or the
      Administrative Agent, as the case may be, has its principal office), or

            (ii) impose, modify or deem applicable any reserve, special deposit
      or similar requirement against assets of, deposits with or for the account
      of, or credit extended by any Bank, the Issuing Bank or the Administrative
      Agent, or

            (iii) impose any other condition with respect to this Agreement, the
      Commitments, any promissory notes issued hereunder or the Loans or any
      Letter of Credit, and the result of any of the foregoing is to increase
      the cost to any Bank, the Issuing Bank or the Administrative Agent, as the
      case may be, of making, funding, maintaining or participating in any
      Eurocurrency Rate Loan, Fixed Rate Loan or Letter of Credit, or to reduce
      the amount of any sum receivable by any Bank, the Issuing Bank or the
      Administrative Agent, as the case may be, thereon,

then the Company shall pay to such Bank, the Issuing Bank or the Administrative
Agent, as the case may be, from time to time, upon request by such Bank or the
Issuing Bank (with a copy of such request to be provided to the Administrative
Agent) or the Administrative Agent, additional amounts sufficient to compensate
such Bank, the Issuing Bank or the Administrative Agent, as the case may be, for
such increased cost or reduced sum receivable to the extent, in the case of any
Eurocurrency Rate Loan, such Bank or the Administrative Agent is not compensated
therefor in the computation of the interest rate applicable to such Eurocurrency
Rate Loan. A statement as to the amount of such increased cost or reduced sum
receivable, prepared in good faith and in reasonable detail by such Bank, the
Issuing Bank or the Administrative Agent, as the case may be, and submitted by
such Bank, the Issuing Bank or the Administrative Agent, as the case may be, to
the Company, shall be conclusive and binding for all purposes absent manifest
error in computation.

            (b) In the event that any applicable law, treaty, rule or regulation
(whether domestic or foreign) now or hereafter in effect and whether or not
presently applicable to any Bank, the Issuing Bank or the Administrative Agent,
or any interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof, or compliance by any
Bank, the Issuing Bank or the Administrative Agent with any guideline, request
or directive of any such authority (whether or not having the force of law),
including any risk-based capital guidelines, affects or would affect the amount
of capital required or expected to be maintained by such Bank, the Issuing Bank
or the Administrative Agent (or any corporation controlling such Bank or the
Administrative Agent) and such Bank, the Issuing Bank or the Administrative
Agent, as the case may be, determines that the amount of such capital is
increased by or based upon the existence of such Bank's, the Issuing Bank's or
the Administrative Agent's obligations hereunder and such increase has the
effect of reducing the rate of return on such Bank's, the Issuing Bank's or the
Administrative Agent's (or such controlling corporation's) capital as a
consequence of such obligations hereunder to a level below that which such Bank,
the Issuing Bank or the Administrative Agent (or such controlling corporation)
could have achieved but for such circumstances (taking into consideration its
policies with respect to capital adequacy) by an amount deemed by such Bank, the
Issuing Bank or the Administrative Agent to be material, then the Company shall
pay to such Bank, the Issuing Bank or the Administrative Agent, as the case may
be, from time to time, upon request by such Bank or the Issuing Bank (with a
copy of such request to be provided to the Administrative Agent) or the
Administrative Agent, additional amounts sufficient to compensate such Bank, the
Issuing Bank or the Administrative Agent (or such controlling corporation) for
any increase in the amount of capital and reduced rate of return which such
Bank, the Issuing Bank or the Administrative Agent reasonably determines to be
allocable to the existence of such Bank's, the Issuing Bank's or the
Administrative Agent's obligations hereunder. A statement as to the amount of
such compensation, prepared in good faith and in reasonable detail by such Bank,
the Issuing Bank or the Administrative Agent, as the case may be, and submitted
by such Bank, the Issuing Bank or the Administrative Agent to the Company, shall
be conclusive and binding for all purposes absent manifest error in computation.

            3.8 Illegality and Impossibility. In the event that any applicable
law, treaty or other international agreement, rule or regulation (whether
domestic or foreign) now or hereafter in effect and whether or not presently
applicable to any Bank, or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration
thereof, or compliance by any Bank with any guideline, request or directive of
such authority (whether or not having the force of law), including without
limitation exchange controls, (a) shall make it unlawful or impossible for any
Bank to maintain any Eurocurrency Rate Loan under this Agreement or (b) shall
make it impracticable, unlawful or impossible for, or shall in any way limit or
impair the ability of, the Company to make or any Bank to receive any payment
under this Agreement at the place specified for payment hereunder or to freely
convert any amount paid into Dollars at market rates of exchange or to transfer
any amount paid or so converted to the Administrative Agent at its offices at
270 Park Avenue, New York, the

New York, the Company shall, upon receipt of notice thereof, convert such
Eurocurrency Rate Loan to a Floating Rate Loan (i) on the last day of the then
current Eurocurrency Interest Period applicable to such Eurocurrency Rate Loan
if such Bank may lawfully continue to maintain such Eurocurrency Rate Loan to
such day, or (ii) immediately if such Bank may not continue to maintain such
Eurocurrency Rate Loan to such day (in which case the Company shall pay all
amounts owing to such Bank under Section 3.9). Such Bank's obligation to make or
continue Eurocurrency Rate Loans, or to convert Floating Rate Loans into
Eurocurrency Rate Loans, shall be suspended until such time as such Bank may
again make and maintain Eurocurrency Rate Loans and the Company may make, or the
Bank may receive, payment under this Agreement as provided herein.

            3.9 Indemnification. If the Company makes any payment of principal
with respect to any Eurocurrency Rate Loan or Fixed Rate Loan on any other date
than the last day of a Eurocurrency Interest Period or Fixed Rate Interest
Period applicable thereto (whether pursuant to Section 3.8, Section 6.2 or
otherwise), or if the Company fails to borrow any Eurocurrency Rate Loan or
Fixed Rate Loan, to continue any Eurocurrency Rate Loan as a Eurocurrency Rate
Loan or to convert any Floating Rate Loan into a Eurocurrency Rate Loan, after
notice has been given to the Banks in accordance with Section 2.1(c)(iv), 2.4 or
2.7, as the case may be, or if the Company fails to make any payment of
principal or interest in respect of a Eurocurrency Rate Loan or Fixed Rate Loan
when due, the Company shall reimburse each Bank on demand for any resulting loss
or expense incurred by each such Bank, including without limitation any loss
incurred in obtaining, liquidating or employing deposits from third parties,
whether or not such Bank shall have funded or committed to fund such Loan. A
statement as to the amount of such loss or expense, prepared in good faith and
in reasonable detail by such Bank and submitted by such Bank to the Company,
shall be conclusive and binding for all purposes absent manifest error in
computation. Calculation of all amounts payable to such Bank under this Section
3.9 in respect of a Eurocurrency Rate Loan shall be made as though such Bank
shall have actually funded or committed to fund the relevant Eurocurrency Rate
Loan through the purchase of an underlying deposit in an amount equal to the
amount of such Loan and having a maturity comparable to the related Eurocurrency
Interest Period.

            3.10 Substitution of Banks. (a) Each Bank agrees that, as promptly
as practicable after it becomes aware of the occurrence of an event or the
existence of a condition that (i) would cause it to incur any increased costs or
render it unable to perform its agreements under Section 3.7 or 3.8, or (ii)
would require the Company to pay an increased amount under Section 3.7 or render
it unable to accept performance under Section 3.8, it will promptly notify the
Administrative Agent, who shall notify the Company, of such event or condition
and, to the extent not inconsistent with such Bank's internal policies, will use
its reasonable efforts to make, fund or maintain the affected Loans of such Bank
through another lending office of such Bank if as a result thereof the
additional monies which would otherwise be required to be paid or the reduction
of amounts receivable by such Bank thereunder in respect of such Loans would be
materially reduced, or such inability to perform would cease to exist, or the
increased costs

                                     - 37 -


which would otherwise be required to be paid in respect of such Loans pursuant
to Section 3.7 would be materially reduced or the taxes or other amounts
otherwise payable under Section 3.7 would be materially reduced, and if, as
determined by such Bank, in its sole discretion, the making, funding or
maintaining of such Loans through such other lending office would not otherwise
materially adversely affect such Loans or such Bank.

            (b) In the event any Bank shall have delivered to the Company a
notice pursuant to Section 3.10(a), that a Eurocurrency Rate Loan is no longer
available from such Bank pursuant to Section 3.8 or that any of the events
designated in Section 3.10(a) have occurred or shall have failed to make its
share of a Loan available in accordance with Section 2.4(b), the Company may
(but subject in any such case to the payments required by Sections 3.1(b) and
3.9), provided that there shall exist no Default or Event of Default, upon at
least five Business Days' prior written, facsimile or telex notice to such Bank
and the Administrative Agent, identify to the Administrative Agent a lending
institution reasonably acceptable to the Administrative Agent which will
purchase the Commitment and the amount of outstanding Loans from the Bank
providing such notice and such Bank shall thereupon assign its Commitment, any
Loans owing to such Bank and any promissory notes held by such Bank to such
replacement lending institution pursuant to Section 8.6. Such notice shall
specify an effective date for such assignment and at the time thereof, the
Company shall pay all accrued interest, facility fees and all other amounts
(including without limitation all amounts payable under Article III) owing
hereunder to such Bank as at such effective date for such assignment.

            3.11 Evidence of Debt. (a) Each Bank shall maintain in accordance
with its usual practice an account or accounts evidencing the indebtedness of
the Company to such Bank resulting from each Loan made by such Bank, including
the amounts of principal and interest payable and paid to such Bank from time to
time hereunder.

            (b) The Administrative Agent shall maintain accounts in which it
shall record (i) the amount of each Loan made hereunder, whether such Loan is a
Eurocurrency Rate Loan, a Floating Rate Loan or a Fixed Rate Loan and the
Eurocurrency Interest Period or Fixed Rate Interest Period applicable thereto,
(ii) the amount of any principal or interest due and payable or to become due
and payable from the Company to each Bank hereunder and (iii) the amount of any
sum received by the Administrative Agent hereunder for the account of the Banks
and each Bank's share thereof.

            (c) The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section 3.11 shall be prima facie evidence of the
existence and amounts of the obligations recorded therein; provided that the
failure of any Bank or the Administrative Agent to maintain such accounts or any
error therein shall not in any manner affect the obligation of the Company to
repay the Loans in accordance with the terms of this Agreement.

            (d) Any Bank may request that Loans made by it be evidenced by a
promissory note. In such event, the Company shall prepare, execute and deliver
to such Bank a promissory note payable to the order of such Bank (or, if
requested by such Bank, to such Bank and its registered assigns) and in a form
approved by the Administrative Agent. Thereafter, the Loans evidenced by such
promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 8.6) be represented by one or more promissory
notes in such form payable to the order of the payee named therein (or, if such
promissory note is a registered note, to such payee and its registered assigns).

available to be drawn at any time prior

to the stated expiry of all outstanding Letters of Credit, or any one or more of
the foregoing, whereupon the Commitments shall terminate forthwith and all such
amounts, including such cash collateral, shall become immediately due and
payable, as the case may be, provided that in the case of any event or condition
described in Section 6.1(h) with respect to the Company, the Commitments shall
automatically terminate forthwith and all such amounts, including such cash
collateral, shall automatically become immediately due and payable without
notice; in all cases without demand, presentment, protest, diligence, notice of
dishonor or other formality, all of which are hereby expressly waived. Such cash
collateral delivered in respect of outstanding Letters of Credit shall be
deposited in a special cash collateral account to be held by the Administrative
Agent as collateral security for the payment and performance of the Company's
obligations under this Agreement to the Banks and the Administrative Agent.

            (b) The Administrative Agent may, with the consent of the Required
Banks, and, upon being directed to do so by the Required Banks, shall, in
addition to the remedies provided in Section 6.2(a), exercise and enforce any
and all other rights and remedies available to it or the Banks, whether arising
under this Agreement, any promissory notes issued hereunder or any Support
Document or under applicable law, in any manner deemed appropriate by the
Administrative Agent, including suit in equity, action at law, or other
appropriate proceedings, whether for the specific performance (to the extent
permitted by law) of any covenant or agreement contained in this Agreement or in
any promissory notes issued hereunder or any Support Document or in aid of the
exercise of any power granted in this Agreement, any promissory note issued
hereunder or any Support Document.

            (c) Upon the occurrence and during the continuance of any Event of
Default, each Bank may, subject to Section 7.11, at any time and from time to
time, without notice to the Company (any requirement for such notice being
expressly waived by the Company) set off and apply against any and all of the
obligations of the Company now or hereafter existing under this Agreement,
whether owing to such Bank or any other Bank or the Administrative Agent, any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank to or for
the credit or the account of the Company and any property of the Company from
time to time in possession of such Bank, irrespective of whether or not such
Bank shall have made any demand hereunder and although such obligations may be
contingent and unmatured. The Company hereby grants to the Banks and the
Administrative Agent a lien on and security interest in all such deposits,
indebtedness and property as collateral security for the payment and performance
of the obligations of the Company under this Agreement. The rights of such Bank
under this Section 6.2(c) are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which such Bank may
have.

            (d) In addition to other amounts payable pursuant to this Agreement,
the Company confirms that it shall further pay all amounts required to be paid
pursuant to Section 3.9. The Company agrees that such amounts are a reasonable
pre-estimate of loss and not a

                                Credit Agreement
<PAGE>   60
                                     - 55 -


penalty. Such amounts are payable as liquidated damages for the loss of bargain
and payment of any such amount shall not in any way reduce, affect or impair any
other obligations of the Company under this Agreement.

                                   ARTICLE VII
                     THE ADMINISTRATIVE AGENT AND THE BANKS

            7.1 Appointment and Authorization. Each Bank hereby irrevocably
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement, any promissory note
issued hereunder and the Support Documents as are delegated to the
Administrative Agent by the terms hereof or thereof, together with all such
powers as are reasonably incidental thereto. The provisions of this Article VII
are solely for the benefit of the Administrative Agent and the Banks, and the
Company shall not have any rights as a third party beneficiary of any of the
provisions hereof. In performing its functions and duties under this Agreement,
the Administrative Agent shall act solely as agent of the Banks and does not
assume and shall not be deemed to have assumed any obligation towards or
relationship of agency or trust with or for the Company.

            7.2 Administrative Agent and Affiliates. Chase, in its capacity as a
Bank hereunder shall have the same rights and powers hereunder as any other Bank
and may exercise or refrain from exercising the same as though it were not the
Administrative Agent. Chase and its Affiliates (and any Bank) may (without
having to account therefor to any Bank) accept deposits from, lend money to, and
generally engage in any kind of banking, trust, financial advisory or other
business with the Company or any Subsidiary of the Company as if it were not
acting as Administrative Agent hereunder, and may accept fees and other
consideration therefor without having to account for the same to the Banks.

            7.3 Scope of Administrative Agent's Duties. The Administrative Agent
shall have no duties or responsibilities except those expressly set forth
herein, and shall not, by reason of this Agreement, have a fiduciary
relationship with any Bank, beyond the agency created herein and subject to the
terms herein, and no implied covenants, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or shall otherwise exist against
the Administrative Agent. As to any matters not expressly provided for by this
Agreement (including, without limitation, collection and enforcement actions
hereunder and under the Support Documents), the Administrative Agent shall not
be required to exercise any discretion or take any action, but the
Administrative Agent shall take such action or omit to take any action pursuant
to the reasonably written instructions of the Required Banks (or, to the extent
required by Section 8.1, all of the Banks) and may request instructions from the
Required Banks. The Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, pursuant to the written instructions of
the Required Banks, which instructions and any action or omission pursuant
thereto shall be binding upon all of the Banks; provided, however, that the
Administrative Agent shall not be required to act or omit to act if, in the
judgment of the

                                Credit Agreement
<PAGE>   61
                                     - 56 -


Administrative Agent, such action or omission may expose the Administrative
Agent to personal liability or is contrary to this Agreement, any promissory
notes issued hereunder or the Support Documents or applicable law.

            7.4 Reliance by Administrative Agent. The Administrative Agent shall
be entitled to rely upon any certificate, notice, document or other
communication (including any cable, telegram, telex, facsimile transmission or
oral communication) reasonably believed by it to be genuine and correct and to
have been sent or given by or on behalf of a proper person. The Administrative
Agent may treat the payee of any promissory note issued hereunder as the holder
thereof. The Administrative Agent may employ agents (including, without
limitation, collateral agents) and may consult with legal counsel (who may be
counsel for the Company), independent public accounts and other experts selected
by it and shall not be liable to the Banks, except as to money or property
received by it or its authorized agents, for the negligence or misconduct of any
such agent selected by it with reasonable care or for any action taken or
omitted to be taken by it in good faith in accordance with the advice of such
counsel, accountants or experts.

            7.5 Default. The Administrative Agent shall not be deemed to have
knowledge of the occurrence of any Default or Event of Default, unless the
Administrative Agent has actual knowledge or has otherwise received written
notice from a Bank or the Company specifying such Default or Event of Default
and stating that such notice is a "Notice of Default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall
promptly give written notice thereof to the Banks. As used herein, "actual
knowledge" shall mean the actual knowledge of the responsible loan officer of
the Administrative Agent, obtained in administering the Company's account.

            7.6 Liability of Administrative Agent. Neither the Administrative
Agent nor any of its directors, officers, agents, or employees shall be liable
to the Banks for any action taken or not taken by it or them in connection
herewith with the consent or at the request of the Required Banks or in the
absence of its or their own gross negligence or willful misconduct. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into or verify
(i) any recital, statement, warranty or representation contained in this
Agreement, any promissory note issued hereunder or any Support Document, or in
any certificate, report, financial statement or other document furnished in
connection with this Agreement, (ii) the performance or observance of any of the
covenants or agreements of the Company or any Guarantor, (iii) the satisfaction
of any condition specified in Article II, and (iv) the validity, effectiveness,
legal enforceability, value or genuineness of this Agreement, any promissory
notes issued hereunder or the Support Documents or any collateral subject
thereto or any other instrument or document furnished in connection herewith.

            7.7 Nonreliance on Administrative Agent and Other Banks. Each Bank
acknowledges and agrees that it has, independently and without reliance on the
Administrative Agent or any other Bank, and based on such documents and
information as it has deemed

                                Credit Agreement
<PAGE>   62
                                     - 57 -


appropriate, made its own credit analysis of the Company and decision to enter
into this Agreement and that it will, independently and without reliance upon
the Administrative Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
analysis and decision in taking or not taking action under this Agreement. The
Administrative Agent shall not be required to keep itself informed as to the
performance or observance by the Company or any Guarantor of this Agreement, any
promissory notes issued hereunder or the Support Documents or any other
documents referred to or provided for herein or to inspect the properties or
books of the Company or any Guarantor and, except for notices, reports and other
documents and information expressly required to be furnished to the Banks by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Bank with any information concerning the
affairs, financial condition or business of the Company or any of its
Subsidiaries which may come into the possession of the Administrative Agent or
any of its Affiliates.

            7.8 Indemnification. The Banks agree to indemnify the Administrative
Agent (to the extent not reimbursed by the Company, but without limiting any
obligation of the Company to make such reimbursement), ratably according to the
respective principal amounts of the Advances then outstanding made by each of
them (or if no Advances are at the time outstanding, ratably according to the
respective amounts of their Commitments), from and against any and all claims,
damages, losses, liabilities, costs or expenses of any kind or nature whatsoever
(including, without limitation, fees and disbursements of counsel) which may be
imposed on, incurred by, or asserted against the Administrative Agent in any way
relating to or arising out of this Agreement or the transactions contemplated
hereby or any action taken or omitted by the Administrative Agent under this
Agreement, provided, however, that no Bank shall be liable for any portion of
such claims, damages, losses, liabilities, costs or expenses resulting from the
Administrative Agent's gross negligence or willful misconduct. Each Bank agrees
to reimburse the Administrative Agent promptly upon demand for its ratable share
of any amounts owing to the Administrative Agent by the Banks pursuant to this
Section. If the indemnity furnished to the Administrative Agent under this
Section shall, in the judgment of the Administrative Agent, be insufficient or
become impaired, the Administrative Agent may call for additional indemnity from
the Banks and cease, or not commence, to take any action until such additional
indemnity if furnished.

            7.9 Resignation or Removal of Administrative Agent. The
Administrative Agent may resign as such at any time upon thirty days' prior
written notice to the Company and the Banks or may be removed for cause as such
upon vote of the Required Banks. In the event of any such resignation or
removal, the Required Banks shall, by an instrument in writing delivered to the
Company and the Administrative Agent, appoint a successor, with the consent of
the Company, which shall be a commercial bank organized under the laws of the
United States or any State thereof and having a combined capital and surplus of
at least $500,000,000. If a successor is not so appointed or does not accept
such appointment before the Administrative Agent's resignation or removal
becomes effective, the resigning or removed Administrative

                                Credit Agreement
<PAGE>   63
                                     - 58 -


Agent may appoint a temporary successor to act until such appointment by the
Required Banks is made and accepted or if no such temporary successor is
appointed as provided above by the resigning or removed Administrative Agent,
the Administrative Agent agrees to continue to perform administrative duties
hereunder for a fee to be agreed upon at such time until such appointment by the
Required Banks is made and accepted. Any successor to the Administrative Agent
shall execute and deliver to the Company and the Banks an instrument accepting
such appointment and thereupon such successor Administrative Agent, without
further act, deed, conveyance or transfer, shall become vested with all of the
properties, rights, interests, powers, authorities and obligations of its
predecessor hereunder with like effect as if originally named as Administrative
Agent hereunder. Upon request of such successor Administrative Agent, the
Company and the resigning or removed Administrative Agent shall execute and
deliver such instruments of conveyance, assignment and further assurance and do
such other things as may reasonably be required for more fully and certainly
vesting and confirming in such successor Administrative Agent all such
properties, rights, interests, powers, authorities and obligations. The
provisions of this Article VII shall thereafter remain effective for such
resigning or removed Administrative Agent with respect to any actions taken or
omitted to be taken by such Administrative Agent while acting as the
Administrative Agent hereunder.

            7.10 Replacement of the Issuing Bank. The Issuing Bank may be
replaced at any time by written agreement among the Company, the Administrative
Agent, the replaced Issuing Bank and the successor Issuing Bank. The
Administrative Agent shall notify the Banks of any such replacement of the
Issuing Bank. At the time any such replacement shall become effective, the
Company shall pay all unpaid fees accrued for the account of the replaced
Issuing Bank pursuant to Section 2.3(b). From and after the effective date of
any such replacement, (i) the successor Issuing Bank shall have all the rights
and obligations of the Issuing Bank under this Agreement with respect to Letters
of Credit to be issued thereafter and (ii) references herein to the term
"Issuing Bank" shall be deemed to refer to such successor or to any previous
Issuing Bank, or to such successor and all previous Issuing Banks, as the
context shall require. After the replacement of an Issuing Bank hereunder, the
replaced Issuing Bank shall remain a party hereto and shall continue to have all
the rights and obligations of an Issuing Bank under this Agreement with respect
to Letters of Credit issued by it prior to such replacement, but shall not be
required to issue additional Letters of Credit.

            7.11 Sharing of Payments. The Banks agree among themselves that, in
the event that any Bank shall obtain payment in respect of any Revolving Credit
Advance or any other obligation owing to all of the Banks under this Agreement
through the exercise of a right of set-off, banker's lien, counterclaim or
otherwise in excess of its ratable share of payments received by all of the
Banks on account of the Revolving Credit Advances and other obligations (or if
no Revolving Credit Advances are outstanding, ratably according to the
respective amounts of the Commitments), such Bank shall promptly purchase from
the other Banks participations in such Revolving Credit Advances and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all of the Banks share such

                                Credit Agreement
<PAGE>   64
                                     - 59 -


payment in accordance with such ratable shares. The Banks further agree among
themselves that if payment to a Bank obtained by such Bank through the exercise
of a right of set-off, banker's lien, counterclaim or otherwise as aforesaid
shall be rescinded or must otherwise be restored, each Bank which shall have
shared the benefit of such payment shall, by repurchase of participations
theretofore sold, return its share of that benefit to each Bank whose payment
shall have been rescinded or otherwise restored. The Company agrees that any
Bank so purchasing such a participation may, to the fullest extent permitted by
law, exercise all rights of payment, including set-off, banker's lien or
counterclaim, with respect to such participation as fully as if such Bank were a
holder of such Revolving Credit Advance or other obligation in the amount of
such participation. The Banks further agree among themselves that, in the event
that amounts received by the Banks and the Administrative Agent hereunder are
insufficient to pay all such obligations or insufficient to pay all such
obligations when due, the fees and other amounts owing to the Administrative
Agent in such capacity shall be paid therefrom before payment of obligations
owing to the Banks under this Agreement. Except as otherwise expressly provided
in this Agreement, if any Bank or the Administrative Agent shall fail to remit
to the Administrative Agent or any other Bank an amount payable by such Bank or
the Administrative Agent to the Administrative Agent or such other Bank pursuant
to this Agreement on the date when such amount is due, such payments shall be
made together with interest thereon for each date from the date such amount is
due until the date such amount is paid to the Administrative Agent or such other
Bank at a rate per annum equal to the rate at which borrowings are available to
the payee in its overnight federal funds market. It is further understood and
agreed among the Banks and the Administrative Agent that if the Administrative
Agent or any Bank shall engage in any other transactions with the Company and
shall have the benefit of any collateral or security therefor which does not
expressly secure the obligations arising under this Agreement except by virtue
of a so-called dragnet clause or comparable provision, the Administrative Agent
or such Bank shall be entitled to apply any proceeds of such collateral or
security first in respect of the obligations arising in connection with such
other transaction before application to the obligations arising under this
Agreement.

            7.12  Documentation Agent.  The First National Bank of Chicago,
in its capacity as Documentation Agent, shall have no obligations, duties or
liabilities whatsoever under this Agreement.

reduce any fees or other amounts payable hereunder, without the written consent
of each Bank affected thereby, (iii) postpone the scheduled date of payment of

thereon, or any fees or other amounts payable hereunder, or reduce the amount
of, waive or excuse any such payment, or postpone the scheduled date of

pursuant to the terms of Section 2.4(d)), without the written consent of each
Bank affected thereby, (iv) change any provision that would alter the pro rata
sharing of payments required hereunder, without the written consent of each
Bank, (v) change any of the provisions of this Section or the definition of
"Required Banks" or any other provision hereof specifying the number or
percentage of Banks required to waive, amend or modify any rights hereunder or
make any determination or grant any consent hereunder, without the written
consent of each Bank or (vi) provide for discharge of all or a substantial
portion of the Guarantors or release all or a substantial portion of the
collateral pledged pursuant the Pledge Agreement (other than in connection with
(A) a corporate reorganization in which the Company substitutes substantially
equivalent collateral or (B) a transaction permitted by Section 5.2(f) or (h)),
without the written consent of each Bank; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent, the Issuing Bank or the Swing Line Bank hereunder without
the prior written consent of the Administrative Agent, the Issuing Bank or the
Swing Line Bank, as the case may be.

officers, directors, employees and agents, from and against any and all claims,
damages, losses, liabilities, costs or expenses of any kind or nature whatsoever
which the Issuing Bank, the Banks or the Administrative Agent or any such person
may incur or which may be claimed against any of them by reason of or in
connection with any Letter of Credit, and neither the Issuing Bank, any Bank or

employees or agents shall be liable or responsible for: (i) the use which may be
made of any Letter of Credit or for any acts or omissions of any beneficiary in
connection therewith; (ii) the validity, sufficiency or genuineness of documents

against presentation of documents which do not comply with the terms of any
Letter of Credit, including failure of any documents to bear any reference or

the Issuing Bank and such other persons, and the Issuing Bank shall be liable to
the Company, to the extent, but only to the extent, of any direct, as opposed to
consequential or incidental, damages suffered by the Company which were caused
by (A) the Issuing Bank's wrongful dishonor of any Letter of Credit after the
presentation to it by the beneficiary thereunder of a draft or other demand for
payment and other documentation strictly complying with the terms and conditions
of such Letter of Credit, or (B) the Issuing Bank's payment to the beneficiary
under any Letter of Credit against presentation of documents which do not comply
with the terms of such Letter of Credit to the extent, but only to the extent,
that such payment constitutes gross negligence or wilful misconduct of the
Issuing Bank. It is understood that in making any payment under a Letter of
Credit the Issuing Bank will rely on documents presented to it under such Letter
of Credit as to any and all matters set forth therein without further
investigation and regardless of any notice or information to the contrary, and
such reliance and payment against documents presented under a Letter of Credit
substantially complying with the terms thereof shall not be deemed gross
negligence or wilful misconduct of the Issuing Bank in connection with such
payment. It is further acknowledged and agreed that the Company may have rights
against the beneficiary or others in connection with any Letter of Credit with
respect to which the Issuing Bank is alleged to be liable and it shall be a
precondition of the assertion of any liability of the Issuing Bank under this
Section that the Company shall first have exhausted all remedies in respect of
the alleged loss against such beneficiary and any other parties obligated or
liable in connection with such Letter of Credit and any related transactions.

            (c) The Company hereby indemnifies and agrees to hold harmless the
Banks and the Administrative Agent, and their respective officers, directors,
employees and agents, from and against any and all claims, damages, losses,
liabilities, costs or expenses of any kind or nature whatsoever (including
reasonable attorneys fees and disbursements incurred in connection with any
investigative, administrative or judicial proceeding whether or not such person
shall be designated as a party thereto) which the Banks or the Administrative
Agent or any such person may incur or which may be claimed against any of them
by reason of or in connection with entering into this Agreement or the
transactions contemplated hereby; provided, however, that the Company shall not
be required to indemnify any such Bank and the Administrative Agent or such
other person, to the extent, but only to the extent, that such claim, damage,
loss, liability, cost or expense is attributable to the gross negligence or
willful misconduct of such Bank or the Administrative Agent, as the case may be.

            8.6 Successors and Assigns. (a) This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns, provided that the Company may not, without the prior consent of the
Banks, assign its rights or obligations hereunder or under any promissory note
issued hereunder or any Support Document and the Banks shall not be obligated to
make any Advance hereunder to any entity other than the Company.

            (b) Any Bank may assign to one or more assignees all or a portion of
its rights and obligations under this Agreement (including all or a portion of
its Commitment and the Loans at the time owing to it); provided that (i) except
in the case of an assignment to a Bank or an Affiliate of a Bank, each of the
Company and the Administrative Agent (and, in the case of an assignment of all
or a portion of a Commitment or any Bank's obligations in respect of Letter of
Credit Advances or Swing Line Loans, the Issuing Bank and the Swing Line Bank)
must give its prior written consent to such assignment (which consent shall not
be unreasonably withheld), (ii) except in the case of an assignment to a Bank or
an Affiliate of a Bank or an assignment of the entire remaining amount of the
assigning Bank's Commitment, the amount of such assignment shall be a multiple
of $1,000,000, the amount of the Commitment of the assigning Bank subject to
each such assignment shall not be less than $10,000,000, and, after giving
effect to such assignment, the assigning Bank's Commitment shall not be less
than $10,000,000, in each case determined as of the date the Assignment and
Acceptance with respect to such assignment is delivered to the Administrative
Agent, unless each of the Company and the Administrative Agent otherwise
consent, (iii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Bank's rights and obligations under this
Agreement, except that this clause (iii) shall not apply to rights in respect of
outstanding Competitive Loans, (iv) the parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Acceptance, together
with a processing and recordation fee of $3,500 (provided that no such
processing and recordation fee shall be required in connection with an
assignment made pursuant to Section 3.10(b)), and (v) the assignee, if it shall
not be a Bank, shall deliver to the Administrative Agent an Administrative
Questionnaire; provided further that any consent of the

                                Credit Agreement
<PAGE>   70
                                     - 65 -


Company otherwise required under this paragraph shall not be required if an
Event of Default under Section 6.1(h) has occurred and is continuing. Upon
acceptance and recording pursuant to paragraph (d) of this Section 8.6, from and
after the effective date specified in each Assignment and Acceptance, the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Bank under this Agreement, and the assigning Bank thereunder shall, to the
extent of the interest assigned by such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Bank's rights and obligations under
this Agreement, such Bank shall cease to be a party hereto but shall continue to
be entitled to the benefits of Sections 3.7, 3.9 and 8.5). Any assignment or
transfer by a Bank of rights or obligations under this Agreement that does not
comply with this paragraph (b) shall be treated for purposes of this Agreement
as a sale by such Bank of a participation in such rights and obligations in
accordance with paragraph (e) of this Section 8.6.

            (c) The Administrative Agent, acting for this purpose as an agent of
the Company, shall maintain at one of its offices in The City of New York a copy
of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Banks, and the Commitment of, and
principal amount of the Advances owing to, each Bank pursuant to the terms
hereof from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Company, the Administrative Agent, the Issuing Bank and the
Banks may treat each Person whose name is recorded in the Register pursuant to
the terms hereof as a Bank hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Company, the Issuing Bank and any Bank, at any reasonable time
and from time to time upon reasonable prior notice.

            (d) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Bank and an assignee, the assignee's completed
Administrative Questionnaire (unless the assignee shall already be a Bank
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section 8.6 and any written consent to such assignment required by
paragraph (b) of this Section 8.6, the Administrative Agent shall accept such
Assignment and Acceptance, record the information contained therein in the
Register and give prompt notice thereof to the Company. No assignment shall be
effective for purposes of this Agreement unless it has been recorded in the
Register as provided in this paragraph.

            (e) Any Bank may, without the consent of the Company, the
Administrative Agent, the Issuing Bank or the Swing Line Bank, sell
participations to one or more banks or other entities (a "Participant") in all
or a portion of such Bank's rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans owing to it);
provided that (i) such Bank's obligations under this Agreement shall remain
unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Company, the
Administrative Agent, the Issuing Bank, the Swing Line Bank and the other Banks
shall continue to deal solely and directly with such Bank in connection with
such

                                Credit Agreement
<PAGE>   71
                                     - 66 -


Bank's rights and obligations under this Agreement. Any agreement or instrument
pursuant to which a Bank sells such a participation shall provide that such Bank
shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such agreement or instrument may provide that such Bank will not, without
the consent of the Participant, agree to any amendment, modification or waiver
described in the first proviso to Section 8.1 that affects such Participant.
Subject to paragraph (f) of this Section 8.6, the Company agrees that each
Participant shall be entitled to the benefits of Sections 3.7, 3.9 and 8.5 to
the same extent as if it were a Bank and had acquired its interest by assignment
pursuant to paragraph (b) of this Section 8.6.

            (f) A Participant shall not be entitled to receive any greater
payment under Section 3.7 or 3.9 than the applicable Bank would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent.

            (g) Any Bank may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of
such Bank, including any such pledge or assignment to a Federal Reserve Bank,
and this Section 8.6 shall not apply to any such pledge or assignment of a
security interest; provided that no such pledge or assignment of a security
interest shall release a Bank from any of its obligations hereunder or
substitute any such assignee for such Bank as a party hereto.

            (h) The Company shall not be liable for any costs or expenses of any
Bank in effecting any participation or assignment under this Section 8.6.

            8.7 Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

            8.8  Governing Law; Jurisdiction; Consent to Service of Process.

            (a) This Agreement shall be construed in accordance with and
governed by the law of the State of New York.

            (b) The Company hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court. Each of
the parties hereto agrees that a final judgment in

                                Credit Agreement
<PAGE>   72
                                     - 67 -


any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that the Administrative Agent
or any Bank may otherwise have to bring any action or proceeding relating to
this Agreement against the Company or its properties in the courts of any
jurisdiction.

            (c) The Company hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection which it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement in any court referred to
in paragraph (b) of this Section 8.8. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such
court.

            (d) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 8.2. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

            8.9 Table of Contents and Headings. The table of contents and the
headings of the various subdivisions hereof are for the convenience of reference
only and shall in no way modify any of the terms or provisions hereof.

            8.10 Construction of Certain Provisions. If any provision of this
Agreement refers to any action to be taken by any person, or which such person
is prohibited from taking, such provision shall be applicable whether such
action is taken directly or indirectly by such person, whether or not expressly
specified in such provision.

            8.11 Integration and Severability. This Agreement embodies the
entire agreement and understanding between the Company and the Administrative
Agent and the Banks, and supersedes all prior agreements and understandings,
relating to the subject matter hereof. In case any one or more of the
obligations of the Company under this Agreement, any promissory notes issued
hereunder or any Support Document shall be invalid, illegal or unenforceable in
any jurisdiction, the validity, legality and enforceability of the remaining
obligations of the Company shall not in any way be affected or impaired thereby,
and such invalidity, illegality or unenforceability in one jurisdiction shall
not affect the validity, legality or enforceability of the obligations of the
Company under this Agreement, any promissory notes issued hereunder or any
Support Document in any other jurisdiction.

            8.12 WAIVER OF JURY TRIAL. EACH OF THE BANKS, THE ADMINISTRATIVE
AGENT AND THE COMPANY, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT
WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF
THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF

                                Credit Agreement
<PAGE>   73
                                     - 68 -


THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT OR ANY OF THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF ANY OF THEM. NONE OF THE BANKS, THE
ADMINISTRATIVE AGENT AND THE COMPANY SHALL SEEK TO CONSOLIDATE, BY COUNTERCLAIM
OR OTHERWISE, ANY SUCH ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED WITH ANY
OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. THESE
PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR
RELINQUISHED BY THE BANKS, THE ADMINISTRATIVE AGENT OR THE COMPANY EXCEPT BY A
WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM. IT IS INTENDED THAT THIS WAIVER
SHALL APPLY TO ANY COUNTERCLAIMS, RIGHTS AND DEFENSES IN CONNECTION THEREWITH.

            8.13 Additional Banks. Additional lenders (each, an "Additional
Bank") may also become Banks hereunder and the aggregate amount of the
Commitments hereunder shall increase accordingly, with the prior written consent
of the Company, each Bank and the Agent, by executing an Assumption Agreement
substantially in the form of Exhibit G hereto. Immediately upon the
effectiveness of any such Assumption Agreement, the Company shall (x) borrow
Eurocurrency Rate Loans and Floating Rate Loans from the Additional Bank(s)
executing such Assumption Agreement and prepay Eurocurrency Rate Loans and
Floating Rate Loans owing to the Banks other than such Additional Bank(s), in
such amounts and in such Permitted Currencies that, after giving effect thereto,
all of the Eurocurrency Rate Loans denominated in the same Permitted Currency
and all of the Floating Rate Loans shall be allocated among the Banks (including
the Additional Bank(s)) pro rata in accordance with the amounts of their
respective Commitments and (y) pay all accrued interest on any Loans so prepaid
and all amounts owing under Section 3.9 by reason of any such prepayment.

                          AGREEMENT AND PLAN OF MERGER


        AGREEMENT AND PLAN OF MERGER dated as of August 22, 1997 by and among
Cambrex Corporation, a Delaware corporation ("Parent"), BW Acquisition
Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (the
"Purchaser"), and BioWhittaker, Inc., a Delaware corporation (the "Company").

        WHEREAS, the respective Boards of Directors of the Parent, the Purchaser
and the Company each has determined that it is fair to, and in the best
interests of, their respective stockholders for Parent to acquire the Company
pursuant to a merger (the "Merger") in which the Purchaser shall be merged with
and into the Company pursuant to this Agreement;

        WHEREAS, as a condition of the willingness of the Parent to enter into
this Agreement, those Persons (as defined in Section 6.5) set forth on Exhibit A
hereto, as the holders of shares of the Company's Common Stock, par value $.01
per share (the "Common Stock"), have entered into two separate but substantially
identical Stockholder Agreements, each dated as of the date hereof
(collectively, the "Stockholder Agreement") with the Parent, which provide,
among other things, that, subject to the terms and conditions thereof, each such
Person will tender such Person's shares of Common Stock in the Offer (as defined
below) and vote such shares of Common Stock in favor of the Merger and the
approval and adoption of this Agreement;

        WHEREAS, as a condition of the willingness of the Parent to enter into
this Agreement (i) the participants of the BioWhittaker, Inc. Supplemental
Executive Retirement Plan (the "SERP") have executed an agreement consenting to
the termination of the rabbi trust established under the SERP (the "Trust")
prior to the payment of any benefits under such Trust and the establishment of a
new rabbi trust which was funded prior to execution to this Agreement by the
Company with 120,344 shares of Common Stock, (ii) pursuant to that agreement,
the other 179,656 shares of Common Stock previously held by the Trust will be
returned to the Company and will be canceled and (iii) all other amounts accrued
or contributed to the Trust pursuant to Article V of the SERP will be
transferred to the new rabbi trust;

        WHEREAS, in furtherance thereof, the Parent proposes that the Purchaser
make an offer to purchase for cash all of the issued and outstanding shares of
Common Stock of the Company, and all associated rights, at a price of $11.625
per share net to the seller;
<PAGE>   5
        WHEREAS, the Boards of Directors of the Parent, the Purchaser and the
Company have approved the Merger following the expiration of such offer, upon
the terms and subject to the conditions set forth herein;

        NOW THEREFORE, in consideration of the mutual covenants and agreements
set forth herein, the parties agree as follows:


                                  1. THE OFFER

        1.1 The Offer. (a) As promptly as practicable, but in no event later
than five business days after the public announcement of the execution of this
Agreement, the Purchaser shall, and the Parent shall cause the Purchaser to,
commence a tender offer (the "Offer") to purchase for cash all of the issued and
outstanding shares of Common Stock (the "Shares"), together with the associated
rights, if any, to purchase Series A participating Cumulative Preferred Stock,
par value $.01 per share ("Series A Shares"; and together with the Shares, the
"Securities") at a price of not less than $11.625 per Security net to the seller
in cash; it being understood that the Offer will not apply to the 179,656 Shares
(or associated rights) previously held by the Trust which are being returned to
the Company and canceled as described in the third recital to this Agreement.
The obligations of the Purchaser and the Parent to consummate the Offer and to
accept for payment and purchase the Securities tendered shall be subject only to
the conditions set forth in Annex A hereto. The Purchaser shall not without the
Company's prior written consent reduce the price per Security or the number of
Securities sought to be purchased or modify the form of consideration to be
received by holders of the Securities in the Offer, increase the condition (the
"Minimum Condition") set forth in clause (i) of the first sentence of Annex A
hereto, impose additional conditions to the Offer or amend any term of the Offer
in a manner materially adverse to the holders of the Securities. Subject only to
the conditions of the Offer set forth in Annex A, the Purchaser shall, and the
Parent shall cause the Purchaser to, pay for all of the Securities validly
tendered and not withdrawn pursuant to the Offer as soon as legally permissible.

        (b) As soon as practicable on the date the Offer is commenced, the
Parent and the Purchaser will file with the Securities and Exchange Commission
(the "Commission") a Tender Offer Statement on Schedule 14D-1 (together with
all supplements or amendments thereto, and including all exhibits, the "Offer
Documents"). The Parent and the Purchaser shall give the Company and its counsel
a reasonable opportunity to review the Offer Documents prior to the filing of
the Offer Documents with the Commission or to the dissemination of the Offer
Documents to the stockholders of the


                                       2
<PAGE>   6
Company. The Parent and the Purchaser will furnish the Company and its counsel
in writing with any comments that the Parent, the Purchaser or their counsel may
receive from the Commission or its staff with respect to the Offer Documents,
promptly after receipt of such comments.

        1.2 Company Action. (a) In connection with the Offer, the Company shall
cause its transfer agent to furnish the Purchaser with mailing labels, security
position listings and any available listings or computer files containing the
names and addresses of record holders of the Shares as of a recent date, and
shall furnish to the Purchaser such information and assistance as the Parent or
the Purchaser may reasonably request in communicating the Offer to the Company's
stockholders. Except for such steps as are necessary to disseminate the Offer
Documents, Parent and the Purchaser shall hold in confidence the information
contained in such labels, listings and filings, will use such information only
in connection with the Offer and, if this Agreement is terminated, will, upon
the request of the Company deliver or cause to be delivered to the Company all
copies of such information then in its possession or in the possession of its
agents or representatives.

        (b) The Company hereby consents to the Offer and represents that the
Board of Directors of the Company (at a meeting duly called and held at which a
quorum was present) as part of its approval of this Agreement has (i) approved
the making of the Offer, (ii) determined that each of the Offer and the Merger
is fair to and in the best interests of the stockholders of the Company and
(iii) resolved to recommend acceptance of the Offer and approval and adoption of
this Agreement by the stockholders of the Company (to the extent such approval
and adoption is required by applicable law). Promptly after the commencement of
the Offer, the Company shall file a Tender Offer Solicitation/Recommendation
Statement on Schedule 14D-9 (together with any amendments or supplements
thereto, and including all exhibits, the "Schedule 14D-9") with respect to the
Offer which shall contain the recommendations of the Board of Directors in favor
of the Offer, the Merger and the Agreement, except to the extent that the Board
of Directors of the Company shall have withdrawn or modified its approval of the
Offer, the Merger and this Agreement in accordance with Section 4.1(b).

        1.3 Board of Directors. (a) Promptly upon the purchase by the Purchaser
of the Securities pursuant to the Offer and from time to time thereafter, the
Purchaser shall be entitled to designate up to the minimum number of directors
necessary in order for the result (expressed as a fraction) derived by dividing
the number of directors so designated by the total number of directors to be at
least equal to the result (expressed as a fraction) derived by dividing the
Shares then held by the Purchaser by the total number of Shares then
outstanding; provided, however, that until the Effective Time


                                       3
<PAGE>   7
(as defined in Section 2.5 hereof) the Board of Directors will have at least two
Independent Directors (as defined in Section 1.3(c) hereof). Upon request by the
Purchaser, the Company shall use its best efforts promptly, at the Company's
election, either to increase the size of the Board or to secure the resignation
of such number of directors as is necessary to enable the Purchaser's designees
to be elected to the Board, and to cause the Purchaser's designees to be so
elected.

        (b) The Company's obligations with respect to the election of the
Purchaser's designees to the Board of Directors of the Company shall be subject
to Section 14(f) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and Rule 14f-1 promulgated thereunder. The Company shall
promptly take all actions required pursuant to Section 14(f) and Rule 14f-1 in
order to fulfill its obligations under this Section 1.3 and shall include in the
Schedule 14D-9 such information with respect to the Company and its officers and
directors as is required under Section 14(f) and Rule 14f-1. The Parent and the
Purchaser will supply to the Company in writing and shall be solely responsible
for any information with respect to any of them and their nominees, officers,
directors and affiliates required by Section 14(f) and Rule 14f-1.

        (c) Following the election or appointment of the Purchaser's designees
pursuant to this Section 1.3 and prior to the Effective Time, any amendment to
this Agreement or of the Certificate of Incorporation or By-Laws of the Company,
any termination of this Agreement by the Company, any extension by the Company
of the time for the performance of any of the obligations or other acts of the
Parent or the Purchaser and any waiver of any of the Company's rights under this
Agreement will require the concurrence of a majority of the directors of the
Company then in office who are (i) not designated by the Purchaser nor otherwise
affiliated with the Parent or the Purchaser, (ii) are not employees or the
Chairman of the Company or any of its subsidiaries and (iii) are not affiliated
with Anasco GmbH (the "Independent Directors").


                                  2. THE MERGER

        2.1 Merger. Upon the terms and subject to the conditions of this
Agreement, and in accordance with the applicable provisions of the Delaware
General Corporation Law ("DGCL"), as promptly as practicable following the
consummation of the Offer, the Purchaser shall be merged with and into the
Company. The Company shall be the surviving corporation in the Merger (sometimes
referred to as the "Surviving Corporation") and shall continue its existence
under the laws of the State of Delaware.


                                       4
<PAGE>   8
The separate existence of the Purchaser shall cease.  The name of the Surviving
Corporation shall be "BioWhittaker, Inc."

        2.2 Effect of Merger. The Certificate of Incorporation and the Bylaws of
the Company in effect upon consummation of the Merger shall be the Certificate
of Incorporation and Bylaws of the Surviving Corporation. The directors of the
Purchaser immediately prior to the Effective Time (as defined in Section 2.5)
shall be the directors of the Surviving Corporation, and the officers set forth
on Schedule 2.2 hereto shall be the officers of the Surviving Corporation, in
each case until their respective successors are duly elected and qualified. The
Merger shall have the effects set forth in Section 259 of the DGCL.

        2.3 Conversion of Shares. Merger Consideration. At the Effective Time,
by virtue of the Merger and without any action on the part of any holder
thereof: (a) each Share, together with the associated right, if any, to purchase
Series A Shares or other securities of the Company pursuant to the Stockholder
Protection Rights Agreement dated January 20, 1995 between the Company and Bank
of Boston, as Rights Agent (the "Rights Agreement"), issued and outstanding
immediately prior to the Effective Time (other than Shares to be canceled
pursuant to clause (b) below and any Dissenting Shares (as defined in Section
2.6)) shall be converted into the right to receive in cash an amount per Share
equal to the Merger Consideration (as defined below), subject to any required
withholding of taxes and without interest; (b) each Share (together with all
associated Series A Shares) owned by Parent, the Purchaser or any other direct
or indirect subsidiary of Parent, or held in the treasury of the Company,
immediately prior to the Effective Time, shall be canceled and extinguished, and
no payment will be made with respect to those Shares; and (c) all shares of
common stock of the Purchaser, par value $.01 per share, then issued and
outstanding shall be converted into an equal number of shares of common stock of
the Surviving Corporation. "Merger Consideration" means (I) $138,948,952, or
such greater price divided by (II) the total number of Shares outstanding on a
fully diluted basis as of immediately prior to the Effective Time, assuming the
exercise of all outstanding Options (as defined below) and including all Shares
acquired by Parent or the Purchaser in the Offer.

        2.4 Stock Options. Immediately prior to the Effective Time, each then
outstanding option to purchase Shares, whether or not then exercisable,
including any options granted under the 1994 Stock Option Plan for Non-Employee
Directors (collectively, the "Options"), shall be canceled by the Company in
exchange for a right to receive a payment in cash in accordance with Section
2.7(b) (the "Option Consideration") equal to the product of (i) the number of
Shares previously subject to the Option and (ii) the excess, if any, of the
Merger Consideration over the exercise price for each Share 


                                       5
<PAGE>   9
under such Option. As of the Effective Time, each holder of an Option will be
entitled to receive only an amount equal to the Option Consideration. All
amounts payable under this Section 2.4 shall be subject to any required
withholding of taxes and shall be paid without interest. Effective as of the
Effective Time and subject to payment of the Option Consideration, the Company
shall cause each stock option or other equity based plan maintained with respect
to any Shares (or rights in respect thereof) (other than the BioWhittaker, Inc.
Savings and Stock Investment Plan (the "BSSIP") and the BioWhittaker, Inc.
Supplemental Executive Retirement Plan (the "SERP")) to be terminated.

        2.5 Consummation of the Merger. Upon the terms and subject to the con-
ditions of this Agreement, the Company shall execute in the manner required by
the DGCL, and deliver to the Secretary of State of the State of Delaware, a duly
executed certificate of merger as required by the DGCL, and the parties shall
take all such other and further actions as may be required by law to make the
Merger effective. Prior to the filing referred to in this Section 2.5, a closing
will be held at the offices of Debevoise & Plimpton, 875 Third Avenue, New York,
New York, on the third business day following the satisfaction of the condition
set forth in Section 5.1(c) hereof (or, in the event the Purchaser shall acquire
at least 90% of the outstanding Shares in the Offer, on the tenth business day
following the completion of the Offer) (or such other time as the Purchaser and
the Company may agree, immediately after the conditions set forth in Article V
have been satisfied or waived) for the purpose of confirming all of the
foregoing. The time the Merger becomes effective in accordance with applicable
law is referred to as the "Effective Time".

        2.6 Dissenters' Rights. Notwithstanding any provision of this Agreement
to the contrary, any shares of capital stock of the Company outstanding
immediately prior to the Effective Time held by a holder who has demanded and
perfected the right, if any, for appraisal of those shares in accordance with
the provisions of Section 262 of the DGCL and as of the Effective Time has not
withdrawn or lost such right to such appraisal ("Dissenting Shares") shall not
be converted into or represent a right to receive the consideration set forth in
Section 2.3, but the holder shall only be entitled to such rights as are granted
by the DGCL. If a holder of shares of capital stock of the Company who demands
appraisal of those shares under the DGCL shall effectively withdraw or lose
(through failure to perfect or otherwise) the right to appraisal, then, as of
the Effective Time or the occurrence of such event, whichever last occurs, those
shares shall be converted into and represent only the right to receive the
consideration as provided in Section 2.3, without interest, upon the surrender
of the certificate or certificates representing those shares. The Company shall
give the Parent (i) prompt notice of any written demands for appraisal of any
shares of capital stock of the


                                       6
<PAGE>   10
Company, attempted withdrawals of such demands, and any other instruments served
pursuant to the DGCL received by the Company relating to stockholders' rights of
appraisal and (ii) the opportunity to direct all negotiations and proceedings
with respect to demands for appraisal under the DGCL. The Company shall not,
except with the prior written consent of Parent, voluntarily make any payment
with respect to any demands for appraisals of capital stock of the Company,
offer to settle or settle any such demands or approve any withdrawal of any such
demands.

        2.7 Payment for Shares and Options. (a) Shares. Prior to the Effective
Time, the Purchaser shall designate a commercial bank or trust company organized
under the laws of the United States or any state of the United States with
capital, surplus and undivided profits of at least $500,000,000 to act as Paying
Agent with respect to the Merger (the "Paying Agent"). Each holder (other than
Parent, the Purchaser or any subsidiary of Parent) of a certificate or
certificates (the "Certificates") which immediately prior to the Effective Time
represented outstanding Shares will be entitled to receive, upon surrender to
the Paying Agent of the Certificates for cancellation, cash in an amount equal
to the product of the number of Shares previously represented by the
Certificates multiplied by the Merger Consideration, subject to any required
withholding of taxes. At or prior to the Effective Time, the Purchaser shall
make available to the Paying Agent sufficient funds to make all payments
pursuant to the preceding sentence. No interest shall accrue or be paid on the
cash payable upon the surrender of the Certificates. If payment is to be made to
a person other than the person in whose name the Certificates surrendered are
registered, it shall be a condition of payment that the Certificates so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting the payment shall pay any transfer or other taxes
required by reason of the payment to a person other than the registered holder
of the Certificates surrendered or establish to the satisfaction of the
Surviving Corporation that the tax has been paid or is not applicable. Following
the Effective Time, until surrendered to the Paying Agent in accordance with the
provisions of this Section 2.7(a), each Certificate shall represent for all
purposes only the right to receive upon surrender thereof the Merger
Consideration multiplied by the number of Shares evidenced by the Certificate,
without any interest, subject to any required withholding taxes. Any funds
delivered or made available to the Paying Agent pursuant to this Section 2.7(a)
and not exchanged for Certificates within six months after the Effective Time
will be returned by the Paying Agent to the Surviving Corporation, which
thereafter will act as Paying Agent, subject to the rights of holders of
unsurrendered Certificates under this Section 2.7(a), and any former
stockholders of the Company who have not previously exchanged their Certificates
will thereafter be entitled to look only to the Surviving Corporation for
payment of their claim for the consideration set forth in Section 2.3, without
any interest, but will have no greater


                                       7
<PAGE>   11
rights against the Surviving Corporation than may be accorded to general
creditors thereof under applicable law. Notwithstanding the foregoing, neither
the Paying Agent nor any party hereto shall be liable to a holder of Shares for
any cash or interest delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws. If any Certificates shall not have
been surrendered prior to three years after the Effective Time (or immediately
prior to such earlier date on which any payment in respect hereof would
otherwise escheat to or become the property of any governmental unit or agency),
the payment in respect of such Certificates shall, to the extent permitted by
applicable laws, become the property of the Surviving Corporation, free and
clear of all claims of interest of any person previously entitled thereto. As
soon as practicable after the Effective Time, the Surviving Corporation will
cause the Paying Agent to mail to each record holder of Certificates a form of
letter of transmittal (which will specify that delivery will be effected, and
risk of loss and title to the Certificates will pass, only upon proper delivery
of the Certificates to the Paying Agent) and instructions for use in effecting
the surrender of the Certificates for payment.

        (b) Options. Each holder of an Option, whether or not then exercisable,
will be entitled to receive cash in an amount equal to the Option Consideration
in respect of such Options (determined in accordance with Section 2.4 hereof),
subject to any required withholding taxes and without interest. As soon as
practicable after the Effective Time, and in any event no more than fifteen (15)
calendar days following the Effective Time, the Surviving Corporation shall
instruct the Paying Agent to pay, and the Paying Agent shall so pay, all amounts
due as Option Consideration to holders of Options as required by this Agreement.

        2.8 Closing of the Company's Transfer Books. At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of Shares
converted into the right to receive the Merger Consideration pursuant to the
terms hereof, Dissenting Shares or Shares to be canceled pursuant to Section 2.3
hereof shall thereafter be made. If, after the Effective Time, Certificates for
such Shares are presented to the Surviving Corporation, they shall be canceled
and exchanged for cash or merely canceled, as the case may be, pursuant to and
in accordance with Sections 2.3, 2.6 and 2.7 hereof, subject to applicable law
in the case of Dissenting Shares.

                        3. REPRESENTATIONS AND WARRANTIES

        3.1 Representations and Warranties of Parent and the Purchaser. The
Parent and the Purchaser represent and warrant to the Company that:

        (a) Corporate Organization. Each of the Parent and the Purchaser is a
    corporation duly organized, validly existing and in good standing under the
    laws of the State of Delaware and has all requisite corporate power to carry
    on its business as it is now being conducted; provided, however, that since
    it was incorporated, the Purchaser has not engaged in any business other
    than organizational matters and matters relating to the Offer and this
    Agreement. Parent owns all of the issued and outstanding capital stock of
    the Purchaser and all such stock has been validly issued and is fully paid
    and nonassessable and is owned by the Parent free and clear of all pledges,
    claims, liens, charges, encumbrances and security interests of any kind or
    nature whatsoever (collectively, "Liens"). Each of Parent and the Purchaser
    is qualified to do business and is in good standing in each jurisdiction in
    which the properties owned, leased or operated by it or the nature of the
    business conducted by it makes such qualification necessary, except where
    the failure to be so qualified and in good standing would not reasonably be
    expected, individually or in the aggregate, to have a Material Adverse
    Effect on Parent. "Material Adverse Effect" means, with respect to any
    person or entity, a material adverse effect on the business, assets,
    liabilities, operations or condition (financial or otherwise) of such person
    or entity and its subsidiaries, taken as a whole. True, accurate and
    complete copies of the Parent's and the Purchaser's Certificates of
    Incorporation and Bylaws, in each case as in effect on the date hereof,
    including all amendments thereto, have heretofore been made available to the
    Company.

        (b) Authority. Each of Parent and the Purchaser has the requisite
    corporate power and authority to execute and deliver this Agreement and to
    carry out their respective obligations pursuant hereto. The execution and
    delivery of this Agreement and the consummation of the transactions
    contemplated hereby have been duly authorized by all necessary corporate or
    other action on the part of each of Parent and the Purchaser. This Agreement
    has been duly executed by Parent and the Purchaser and, assuming due
    authorization, execution and delivery by the Company, constitutes a valid
    and binding obligation of each of them, enforceable against each of them in
    accordance with its terms, except as may be limited by bankruptcy,
    insolvency, moratorium or other similar laws affecting or relating to
    enforcement of creditors' rights generally or by general principles of
    equity. No other corporate actions or proceedings on the part of Parent or
    the Purchaser are necessary to authorize this Agreement, the consummation,
    by either of them, of


                                       9
<PAGE>   13
    the transactions contemplated hereby or the discharge, by either of them, of
    their respective obligations pursuant hereto.

        (c) Consents; No Violation. None of the execution and delivery of this
    Agreement by Parent or the Purchaser, the consummation by each of them of
    the transactions contemplated by this Agreement or the discharge, by either
    of them, of its respective obligations hereunder will (i) conflict with, or
    result in any breach or violation of, any provision of the Parent's or the
    Purchaser's Certificate of Incorporation or By-laws; (ii) constitute, with
    or without notice, the passage of time or both, a breach, violation or
    default, create a lien, or give rise to any right of termination,
    modification, cancellation, prepayment, acceleration or loss of material
    benefit under any law, order, judgment, writ, injunction, decree, statute,
    rule or regulation, governmental permit or license (collectively "Laws"), or
    any mortgage, indenture, lease, license, agreement or other instrument of
    Parent, the Purchaser or any of their respective subsidiaries, or to which
    Parent, the Purchaser or any of their respective subsidiaries or any of
    their respective properties is subject, except for breaches, violations,
    defaults, liens, or rights of termination, modification, cancellation,
    prepayment or acceleration which would not reasonably be expected,
    individually or in the aggregate, to have a Material Adverse Effect on
    Parent or materially adversely affect the ability of Parent or the Purchaser
    to consummate the transactions contemplated hereby; or (iii) require any
    consent, approval or authorization of, notification to, or filing with, any
    court, govern mental agency or regulatory or administrative authority,
    foreign or domestic (each, a "Governmental Entity") or any third party, on
    the part of Parent or the Purchaser, other than (w) the filing of a
    certificate of merger with respect to the Merger in accordance with the
    DGCL, (x) any applicable filings under federal or state securities, "Blue
    Sky" or state anti-takeover laws, (y) filings required pursuant to the
    Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
    Act"), and (z) consents, approvals, authorizations, notifications or
    filings the failure of which to be obtained or made would not reasonably be
    expected, individually or in the aggregate, to have a Material Adverse
    Effect on the Parent or materially adversely affect the ability of the
    Parent or the Purchaser to consummate the transactions contemplated hereby.

        (d) Offer Documents; Schedule 14D-9. None of the Offer Documents will,
    on the date filed with the Commission or on the date first published, sent
    or given to the Company's stockholders, contain any untrue statement of a
    material fact or omit to state any material fact required to be stated
    therein or necessary in order to make the statements therein, in light of
    the circumstances under which they were made, not misleading; provided,
    however, that the foregoing shall not apply to the


                                       10
<PAGE>   14
    extent that any such untrue statement of a material fact or omission to
    state a material fact was made by the Parent or the Purchaser in reliance
    upon and in conformity with written information furnished to the Parent or
    the Purchaser by the Company specifically for use in the Offer Documents.
    The Offer Documents will comply in all material respects, both as to form
    and otherwise, with the requirements of the Exchange Act and the rules and
    regulations thereunder. None of the information supplied or to be supplied
    in writing by the Parent or the Purchaser specifically for inclusion in the
    Schedule 14D-9 will, at the time the Schedule 14D-9 is filed with the
    Commission, contain any untrue statement of a material fact, or omit to
    state any material fact required to be stated therein or necessary in order
    to make the statements therein, in light of the circumstances under which
    they were made, not misleading.

        (e) Financing. Parent and the Purchaser, collectively, have sufficient
    funds available to pay the aggregate Merger Consideration and Option
    Consideration contemplated by this Agreement and to pay all of its fees and
    expenses related to the transactions contemplated hereby.

        (f) No Other Representations or Warranties. Except for the
    representations and warranties contained in this Section 3.1, none of
    Parent, the Purchaser or any other Person makes any other express or implied
    representation or warranty on behalf of Parent, the Purchaser or any of
    their respective affiliates.

        3.2 Representations and Warranties of the Company. The Company repre-
sents and warrants to Parent and the Purchaser that:

        (a) Corporate Organization. Each of the Company and each of its sub-
    sidiaries is a corporation duly organized, validly existing and, except as
    otherwise indicated on the Disclosure Schedule, is in good standing under
    the laws of the jurisdiction in which it is incorporated and has the
    requisite corporate power to own, lease and operate its properties and
    assets and to carry on its businesses as they are now being conducted. The
    Company has delivered to Parent copies of the Certificates of Incorporation
    and By-laws, as amended to this date, of the Company and each of its
    subsidiaries, which Certificates and By-laws are in full force and effect.

        (b) Capitalization. The authorized capital stock of the Company consists
    of 40,000,000 Shares, and 5,000,000 shares of Preferred Stock, par value
    $.01 per share, of which 150,000 shares have been designated Series A
    Participating Cumulative Preferred Stock. As of the date hereof (and
    assuming the return and


                                       11
<PAGE>   15
    cancellation of the 179,656 Shares previously held by the Trust, as
    described in the third recital to this Agreement), (i) 10,881,210 Shares are
    issued and outstanding, all of which are validly issued, fully paid and
    nonassessable and not subject to preemptive rights except as described on
    the Disclosure Schedule delivered by the Company to Parent on the date
    hereof (the "Disclosure Schedule"); (ii) 179,656 Shares are held in the
    treasury of the Company as treasury stock; (iii) there are outstanding
    Options to purchase an aggregate of 1,071,388 Shares; and (iv) there are no

    there are no stock appreciation rights outstanding. The Disclosure Schedule
    sets forth a list, complete and correct as of the date hereof, of the
    holders of all Options and the number of Shares issuable upon the exercise
    of each such Option and the exercise prices thereof. There are no bonds,
    debentures, notes or other indebtedness of the Company having the right to
    vote (or convertible into, or exchangeable for, securities having the right
    to vote) on any matters on which stockholders of the Company may vote.
    Except as set forth in this Section 3.2(b) or on the Disclosure Schedule, no
    shares of capital stock or other voting securities are issued, reserved for
    issuance or outstanding, nor are there any outstanding subscriptions,
    options, warrants, rights, convertible securities or other agreements or
    commitments of any character relating to the issued or unissued capital
    stock or other securities of the Company or any of its subsidiaries
    obligating the Company or any of its subsidiaries to issue, deliver, sell or
    purchase, or cause to be issued, delivered, sold or purchased, any
    securities of the Company or any of its subsidiaries. Except as set forth
    on the Disclosure Schedule, there are no voting trusts or other agreements
    or understandings to which the Company or any of its subsidiaries is a party
    with respect to the voting of capital stock of the Company or any of its
    subsidiaries.

        (c) Subsidiaries. The Disclosure Schedule sets forth a list, true and
    complete as of the date hereof, of all of the subsidiaries of the Company.
    All of the out standing shares of capital stock of each subsidiary of the
    Company have been validly issued and are fully paid and nonassessable and
    are owned by the Company or by a subsidiary of the Company are free and
    clear of any Liens. Except for the capital stock of its subsidiaries or as
    set forth on the Disclosure Schedule, as of the date hereof, the Company
    does not own, directly or indirectly, any capital stock or other ownership
    interest in any corporation, limited liability company, partnership, joint
    venture or other entity.

        (d) Authority. The Company has the requisite corporate power and
    authority to execute and deliver this Agreement and to carry out its
    obligations pursuant hereto. The execution and delivery of this Agreement
    and the consummation of


                                       12
<PAGE>   16
    the transactions contemplated hereby have been duly authorized by all
    necessary corporate action on the part of the Company, subject only, to the
    extent required by law, to approval by the stockholders of the Company as
    provided in Section 4.7 or as set forth on the Disclosure Schedule. This
    Agreement has been duly executed and delivered by, and, assuming due
    authorization, execution and delivery by Parent and the Purchaser,
    constitutes a valid and binding obligation of the Company, enforceable
    against the Company in accordance with its terms, except as may be limited
    by bankruptcy, insolvency, moratorium or other similar laws affecting or
    relating to the enforcement of creditors' rights generally or by general
    principles of equity. Except as set forth on the Disclosure Schedule and for
    the approval by the stockholders of the Company as provided in Section 4.7,
    no other corporate actions or proceedings on the part of the Company or its
    stockholders are necessary to authorize this Agreement, the Offer, the
    Merger or the consummation of the transactions contemplated hereby or its
    discharge of its obligations pursuant hereto.

        (e) Consents; No Violation. None of the execution and delivery of this
    Agreement by the Company, the consummation of the transactions contemplated
    hereby or the discharge of its obligations hereunder will, except as set
    forth on the Disclosure Schedule (i) conflict with, or result in a breach or
    a violation of, any provision of the Certificate of Incorporation or By-laws
    of the Company or any of its subsidiaries; (ii) constitute, with or without
    notice, the passage of time or both, a breach, violation or default, create
    a Lien, or give rise to any right of termination, modification,
    cancellation, prepayment, acceleration or the loss of any material benefit
    under any Laws or any mortgage, indenture, lease, license, agreement or
    other instrument of the Company or any of its subsidiaries, or to which the
    Company or any of its subsidiaries or any of their respective properties is
    subject, except for breaches, violations, defaults, liens, or rights of
    termination, modification, cancellation, prepayment or acceleration which
    would not reasonably be expected, individually or in the aggregate, to have
    a Material Adverse Effect on the Company or materially adversely affect the
    ability of the Company to consummate the transactions contemplated hereby;
    or (iii) require any consent, approval or authorization of, notification to,
    or filing with, any Governmental Entity or from any other third parties, on
    the part of the Company or any of its subsidiaries other than (v) required
    consents identified on the Disclosure Schedule, (w) the filing of a
    certificate of merger with respect to the Merger in accordance with the
    DGCL, (x) filings required under the HSR Act, (y) any applicable filings
    under federal and state securities laws or state anti-takeover laws, and (z)
    consents, approvals, authorizations, notifications or filings the failure of
    which to be obtained or made would not reasonably be expected, individually
    or in the aggregate, to have a


                                       13
<PAGE>   17
    Material Adverse Effect on the Company or materially adversely effect the
    ability of the Company to consummate the transactions contemplated hereby.

        (f) SEC Reports; Company Assets and Liabilities. The Company has filed
    all forms, reports, statements and schedules with the Commission required to
    be filed pursuant to the Exchange Act, and the Commission Rules, since
    January 1, 1995 (the "SEC Reports"). As of their respective filing dates,
    the SEC Reports complied in all material respects with all applicable
    requirements of the Exchange Act and the Commission Rules applicable to such
    SEC Reports, and did not contain any untrue statement of a material fact or
    omit to state a material fact required to be stated therein or necessary in
    order to make the statements made therein, in light of the circumstances
    under which they were made, not misleading. The audited and unaudited
    consolidated financial statements of the Company included (or incorporated
    by reference) in the SEC Reports comply as to form in all material respects
    with applicable accounting requirements and the published rules and
    regulations of the Commission with respect thereto, have been prepared in
    accordance with generally accepted accounting principles applied on a
    consistent basis (except as stated in the financial statements, including
    the related notes, and except that the quarterly financial statements do not
    contain all of the footnote disclosures required by generally accepted
    accounting principles) and fairly present, in all material respects, the
    financial position of the Company and its consolidated subsidiaries as of
    the respective dates thereof and the results of their operations,
    stockholders' equity and cash flows for the periods then ended, subject, in
    the case of the unaudited financial statements, to normal year-end
    adjustments and any other adjustments described therein. Except for
    liabilities and obligations incurred in the ordinary course of business
    consistent with past practices since the date of the most recent
    consolidated balance sheet included in the SEC Reports, neither the Company
    nor any of its subsidiaries has incurred any material liabilities or
    obligations of any nature (whether accrued, absolute, contingent or
    otherwise) other than those reflected in the SEC Reports and on the
    Disclosure Schedule and those incurred in connection with the transactions
    contemplated hereby.

        (g) No Material Adverse Change. Except as and to the extent disclosed in
    the SEC Reports or as set forth in the Disclosure Schedule, since October
    31, 1996, there has not been (i) any material adverse change in the
    business, operations or condition (financial or other) of the Company and
    its subsidiaries taken as a whole, (ii) any declaration, setting aside or
    payment of any dividend or other distribution (whether in cash, stock or
    property) with respect to any of the Company's capital stock, (iii) any
    split, combination or reclassification of any of the Company's capital stock
    or any issuance or the authorization of the issuance of any securities


                                       14
<PAGE>   18
    in respect of or in substitution for shares of its capital stock, (iv) any
    granting by the Company (x) to any executive officer or other key employee
    of the Company of any increase in compensation, except for normal increases
    in the ordinary course of business consistent with past practice or as
    required under employment agreements in effect as of the date of the most
    recent SEC Reports or set forth in the Disclosure Schedule or (y) to any
    such executive officer of any increase in severance or termination pay,
    except as was required under any employment, severance or termination
    agreements in effect as of the date of the most recent SEC Reports or set
    forth in the Disclosure Schedule, (v) any damage, destruction or loss,
    whether or not covered by insurance, that could reasonably be expected to
    have a Material Adverse Effect or (vi) except as may have been required by a
    change in generally accepted accounting principles or as disclosed in the
    SEC Reports, any change in accounting methods, principles or practices by
    the Company or any of its subsidiaries materially affecting its assets,
    liabilities or business.

        (h) Offer Documents; Schedule 14D-9. None of the information supplied in
    writing by the Company specifically for inclusion in the Offer Documents
    will, at the respective times the Offer Documents or any amendments or
    supplements thereto are filed with the Commission, contain any untrue
    statement of a material fact or omit to state any material fact required to
    be stated therein or necessary in order to make the statements therein, in
    light of the circumstances under which they were made, not misleading. The
    Schedule 14D-9 on the date filed with the Commission will not contain any
    untrue statement of a material fact or omit to state any material fact
    required to be stated therein or necessary in order to make the statements
    therein, in light of the circumstances under which they were made, not
    misleading; provided, however, that the foregoing shall not apply to the
    extent that any such untrue statement of a material fact or omission to
    state a material fact was made by the Company in reliance upon and in
    conformity with written information furnished to the Company by the Parent
    or the Purchaser specifically for use in the Schedule 14D-9. The Schedule
    14D-9 will comply in all material respects, both as to form and otherwise,
    with the requirements of the Exchange Act and the rules and regulations
    thereunder.

        (i) Litigation. Except as disclosed in the SEC Reports or on the
    Disclosure Schedule, there is no suit, action or proceeding pending or, to
    the knowledge of the Company, threatened against or affecting the Company or
    any of its subsidiaries that individually or in the aggregate would
    reasonably be expected (i) to have a Material Adverse Effect on the Company,
    (ii) as of the date hereof, to impair the ability of the Company to perform
    its obligations under this Agreement in any material respect or (iii) as of
    the date hereof, to delay in any material respect or


                                       15
<PAGE>   19
    prevent the consummation of any of the transactions contemplated by this
    Agreement, nor is there any judgment, decree, injunction, rule or order of
    any Governmental Entity or arbitrator outstanding against the Company or
    any of its subsidiaries having, or which would reasonably be expected to
    have a Material Adverse Effect on the Company.

        (j) Fees. Except as set forth on the Disclosure Schedule, neither the
    Company nor any of its subsidiaries has paid or become obligated to pay any
    fee or commission to any broker, finder or intermediary or other similar
    Person in connection with the transactions contemplated hereby or in
    connection with any other offer to acquire the Company's shares or assets.

        (k) Certificate and By-laws. Neither the Certificate of Incorporation
    nor the By-laws of the Company contains any provision that would require a
    vote of the Company's stockholders in excess of a majority of the
    outstanding shares of Company Common Stock in order to approve the Merger in
    accordance with the terms of this Agreement.

        (l) State Takeover Statutes. The Board of Directors of the Company has
    approved the terms of this Agreement and the Stockholder Agreement and the
    consummation of the Merger and the other transactions contemplated by this
    Agreement and the Stockholder Agreement, and such approval is sufficient to
    render inapplicable to the Merger and the other transactions contemplated by
    this Agreement and the Stockholder Agreement the provisions of Section 203
    of the DGCL. To the Company's knowledge, no state takeover statute or
    similar statute or regulation applies or purports to apply to the Merger,
    this Agreement or any of the transactions contemplated by this Agreement,
    and except for the Rights Agreement and related Series A Shares, no
    provision of the Certificate of Incorporation, By-laws or other governing
    instruments of the Company or any of its subsidiaries would, directly or
    indirectly, restrict or impair the ability of Parent to vote, or otherwise
    to exercise the rights of a stockholder with respect to, shares of the
    capital stock of Company and its subsidiaries that may be acquired or
    controlled by Parent.

        (m) Employee Benefit Plans: Employee Agreements. The Disclosure Schedule
    sets forth a true and complete list of each employee benefit plan within the
    meaning set forth in Section 3(3) of the Employee Retirement Income Security
    Act of 1974, as amended ("ERISA") and each bonus, incentive, deferred
    compensation, severance, termination, retention, change of control, stock
    option or other equity-based performance or other compensation plan,
    program, arrangement,


                                       16
<PAGE>   20
    policy or understanding, whether written or unwritten, that is maintained by
    the Company or any other Person that, together with the Company, is treated
    as a single employer under Section 414 of the Internal Revenue Code of 1986,
    as amended (the "Code") (each a "Commonly Controlled Entity"), or to which
    the Company or any Commonly Controlled Entity contributes or is obligated or
    required to contribute or with regard to which the Company or any of its
    Commonly Controlled Entities has knowledge of any event, transaction or
    condition that would reasonably be expected to result in any material
    liability at the Effective Time (collectively, the "Plans"). Each employment
    agreement to which the Company or any of its subsidiaries is a party, and
    each employee benefit plan adopted by the Company or any of its
    subsidiaries, which in either case becomes effective or grants rights to any
    person upon a "change of control" of the Company is set forth in the
    Disclosure Schedule. True and complete copies of each such Plan and the most
    recent annual report on Form 5500 for each such Plan have been delivered to
    the Purchaser.

        Each Plan intended to be qualified under Section 401(a) of the Code and
    the trust forming a part thereof has received a favorable determination
    letter from the Internal Revenue Service (the "IRS") as to its qualification
    under the Code and to the effect that each such trust is exempt from
    taxation under Section 501(a) of the Code and the Company knows of no event
    that has occurred since the date of such determination that would reasonably
    be expected to adversely affect such qualification or tax-exempt status.

        Except as set forth in the Disclosure Schedule, no material liability
    has been or, to the knowledge of the Company, is expected to be incurred by
    the Company or any Commonly Controlled Entity (either directly or
    indirectly, including as a result of an indemnification obligation or any
    joint and several liability obligations) as the result of a violation of
    Title I of ERISA or an "accumulated funding deficiency" as defined in
    Section 412 of the Code or Section 302 of ERISA or under or pursuant to
    Title IV of ERISA or the penalty or excise tax provisions of Chapter 43 of
    Subtitle D of the Code relating to employee benefit plans, and the Company
    knows of no event, transaction or condition that has occurred or exists with
    respect to the Company's employee benefit plans that would reasonably be
    expected to result in any such material liability to the Purchaser, the
    Surviving Corporation or any Commonly Controlled Entity or any employee
    benefit plan of the Surviving Corporation or any Commonly Controlled Entity.

        Except as otherwise set forth in the Disclosure Schedules, no benefit
    that is payable, or which may become payable as a result of the transactions
    contemplated


                                       17
<PAGE>   21
    hereunder, to any employee pursuant to any Plan shall constitute an "excess
    parachute payment" (as defined in Section 280G(b)(1) of the Code) which is
    subject to the imposition of an excise tax under Section 4999 of the Code or
    which would not be deductible by reason of Section 280G of the Code.

        (n) Compliance with Applicable Laws. Except as disclosed in the SEC
    Reports, the Company and each of its subsidiaries has in effect all Federal,
    state and local governmental approvals, authorizations, certificates,
    filings, franchises, licenses, notices, permits and rights ("Permits")
    necessary for it to own, lease or operate its properties and assets and to
    carry on its business as now conducted, and there has occurred no default
    under any such Permit, except for the lack of Permits and for defaults under
    Permits which lack of, or default under, individually or in the aggregate
    would not have a Material Adverse Effect on the Company. Except as disclosed
    in the SEC Reports, the Company and its subsidiaries are in compliance with
    all applicable statutes, laws, ordinances, rules, orders and regulations of
    any Governmental Entity, except for possible noncompliance which,
    individually or in the aggregate, would not have a Material Adverse Effect
    on the Company.

        (o) Contracts; Debt Instruments. Except as set forth on the Disclosure
    Schedules, (i) neither the Company nor any of its subsidiaries is in
    violation of or in default under (nor to the knowledge of the Company does
    there exist any condition which upon the passage of time, the giving of
    notice or both would cause such a violation of or default under) any loan or
    credit agreement, note, bond, mortgage, indenture, lease, permit,
    concession, franchise, license or any other contract, agreement, arrangement
    or understanding to which it is a party or by which it or any of its
    properties or assets is bound, except for violations or defaults that,
    individually or in the aggregate, would not reasonably be expected to have a
    Material Adverse Effect on the Company.

        (ii) The Company has made available to Parent (x) true and correct
    copies of all loan or credit agreements, notes, bonds, mortgages, indentures
    and other agreements and instruments pursuant to which any indebtedness of
    the Company or any of its subsidiaries in an aggregate principal amount in
    excess of $500,000 is outstanding or may be incurred and (y) accurate
    information regarding the respective principal amounts currently outstanding
    thereunder. For purposes of this Agreement, "indebtedness" shall mean, with
    respect to any Person, without duplication, (A) all obligations of such
    Person for borrowed money, or with respect to deposits or advances of any
    kind to such Person, (B) all obligations of such Person evidenced by bonds,
    debentures, notes or similar instruments, (C) all obligations of

    relating to property purchased by such Person, (D) all obligations of such
    Person issued or assumed as the deferred purchase price of property or
    services (excluding obligations of such Person to creditors for raw
    materials, inventory, services and supplies incurred in the ordinary course
    of such Person's business), (E) all capitalized lease obligations of such
    Person, (F) all obligations of others secured by any Lien on property or
    assets owned or acquired by such Person, whether or not the obligations
    secured thereby have been assumed, (G) all obligations of such Person under
    interest rate or currency hedging transactions (valued at the termination
    value thereof), (H) all letters of credit issued for the account of such
    Person and (I) all guarantees and arrangements having the economic effect of
    a guarantee of such Person of any indebtedness of any other person.

        (p) Taxes and Tax Returns. Except as set forth in the SEC Reports or on
    the Disclosure Schedule: (i) all material tax returns, declarations,
    reports, estimates, information returns and statements required to be filed
    with respect to Taxes (as defined herein) under Federal, state, local or
    foreign laws ("Returns") by or with respect to the Company or any subsidiary
    of the Company have been timely filed (taking into account any extensions of
    time for filing such Returns); (ii) at the time filed, such Returns were
    true, correct and complete in all material respects; (iii) the Company and
    each subsidiary of the Company has timely paid or made provision in
    accordance with generally accepted accounting principles (or there has been
    paid or provision has been made on its behalf) for all material Taxes for
    all periods or portions thereof through the date hereof; (iv) there are no
    material liens for Taxes upon the assets of the Company or any subsidiary of
    the Company which are not provided for in the most recent financial
    statements included in the SEC Reports, except liens for Taxes not yet due;
    (v) there are no material outstanding deficiencies for any Taxes proposed,
    asserted or assessed against the Company or any subsidiary of the Company
    which are not provided for in the most recent financial statements included
    in the SEC Reports; (vi) there are no material Federal, state, local or
    foreign audits or other administrative proceedings or judicial proceedings
    presently pending with regard to any Taxes or Returns required to be filed
    by or with respect to the Company or any of its subsidiaries; (vii) the
    Company has filed a consolidated Return for Federal income tax purposes on
    behalf of itself and all of its domestic subsidiaries as the common parent
    corporation of an "affiliated group" (within the meaning of Section 1504(a)
    of the Code) of which such subsidiaries are "includible corporations" in
    such affiliated group within the meaning of Section 1504(b) of the Code;
    (viii) the Internal Revenue Service has completed examinations of the
    Federal income tax returns filed by or with respect to the Company (or the
    statute of limitations for the assessment of Federal income taxes for such
    period


                                       19
<PAGE>   23
    has expired) for all periods through and including the Company's taxable
    year ended October 31, 1994; (ix) none of the Company or any of its
    subsidiaries has been a member of an "affiliated group" (as defined above),
    or any similar affiliated, combined or consolidated group for state, local
    or foreign tax purposes (other than a group the common parent of which is
    the Company), or has any liability for the Taxes of any person (other than
    the Company or its current subsidiaries) under Treasury Regulation Section
    1.1502-6 or any similar provision of state, local or foreign law or as a
    transferee, successor, by contract or otherwise; (x) the Company has not
    (A) breached any covenant or representation contained in the Tax Agreement
    between the Company and Whittaker Corporation, dated as of September 24,
    1991, or the amendment thereto dated October 23, 1991 (collectively, the
    "Tax Agreement") or (B) entered into any of the transactions described in
    Section 2(c)(ii)(y) of the Tax Agreement and (xi) except as set forth in the
    Disclosure Schedule, neither the Company nor any of its subsidiaries is a
    party to any material tax sharing, tax indemnity or other agreement or
    arrangement with respect to Taxes with any entity not included in the
    Company's most recent financial statements included in the SEC Reports. For
    purposes of this Agreement, "Taxes" means all income, gross income, gross
    receipts, premium, sales, use, transfer, franchise, profits, withholding,
    payroll, employment, excise, severance, property and windfall profits
    taxes, and all other taxes, assessments or similar charges of any kind
    whatsoever thereon or applicable thereto, together with any interest and any
    penalties, additions to tax or additional amounts, in each case imposed by
    any taxing authority (domestic or foreign) upon the Company or any
    subsidiary of the Company, including, without limitation, all amounts
    imposed as a result of being a member of any affiliated or combined group.

        (q) Labor Matters. Neither the Company nor any of its subsidiaries is
    the subject of any suit, action or proceeding which is pending or, to the
    knowledge of the Company, threatened, asserting that the Company or any of
    its subsidiaries has committed an unfair labor practice (within the meaning
    of the National Labor Relations Act or applicable state statutes) or seeking
    to compel the Company or any of its subsidiaries to bargain with any labor
    organization as to wages and conditions of employment, in any such case,
    that would reasonably expected to have a Material Adverse Effect on the
    Company. No strike or other labor dispute involving the Company or any of
    its subsidiaries is pending or, to the knowledge of the Company, threatened,
    and, to the knowledge of the Company, there is no activity involving any
    employees of the company or any of its subsidiaries seeking to certify a
    collective bargaining unit or engaging in any other organizational activity,
    except for any such dispute or activity which would not reasonably be
    expected to have a Material Adverse Effect on the Company.


                                       20
<PAGE>   24
        (r) Environmental Matters. (i) Except as set forth on the Disclosure
    Schedule or in the SEC Reports, the Company's and each of its subsidiaries'
    operation and use of its respective assets, including its owned and leased
    real property, are in compliance in all respects with all applicable Laws
    relating to the protection of human health or the environment
    ("Environmental Laws"), except to the extent that any such noncompliance
    would not have a Material Adverse Effect on the Company. The Company and
    each of its subsidiaries has obtained all environmental, health and safety
    permits necessary for the operation of its respective business as presently
    conducted, and all such permits are in full force and effect and the Company
    and each of its subsidiaries is in compliance in all respects with the terms
    and conditions of each such permit, except, in each case, to the extent that
    any failure to obtain a permit or any such noncompliance would not have a
    Material Adverse Effect on the Company. Except as set forth on the
    Disclosure Schedule, neither the Company nor any of its subsidiaries has
    received any notice of, and, to the knowledge of the Company there is not,
    any administrative or judicial investigation, proceeding or action with
    respect to any material violation, alleged or proven, of Environmental Laws
    by the Company or any its subsidiaries or otherwise involving their
    respective owned or leased real property.

        (ii) Except as set forth on the Disclosure Schedule, to the knowledge of
    the Company, neither the Company nor any of its subsidiaries has taken or
    failed to take any action that has resulted in or will result in any
    liability or obligation relating to (x) the environmental conditions on,
    under, or about the assets of the Company or any of its subsidiaries or any
    of their respective owned or leased real property, or any properties owned,
    leased, operated or used by the Company or any of its subsidiaries or any
    predecessor of the Company or any of its subsidiaries at the present time or
    in the past, including, without limitation, the air, soil and groundwater
    conditions at such properties or (y) the past or present use, management,
    handling, transport, treatment, generation, storage, disposal or release of
    any Hazardous Substances (as defined in Section 6.5), except in the case of
    clauses (x) and (y) above, to the extent such liability or obligation would
    not have a Material Adverse Effect.

        (s) Rights Agreement. The Board of Directors of the Company (at a
    meeting duly called and held at which a quorum was present) as part of its
    approval of this Agreement has resolved to amend (and the Company has caused
    such amendments to become effective prior to the execution of this Agreement
    and the Stockholder Agreement) the Rights Agreement so that (i) neither the
    Parent, the Purchaser nor any of their respective affiliates shall
    constitute an Acquiring Person for any purpose of the Rights Agreement and
    (ii) neither the execution or delivery of this


                                       21
<PAGE>   25
    Agreement or the Stockholders Agreement, nor the consummation of any or all
    of the transactions contemplated by this Agreement or the Stockholders
    Agreement, will trigger the exercisability of the Rights (as defined in the
    Rights Agreement) or the separation of the Rights from the shares to which
    they are attached, or cause the Distribution Date (as defined in the Rights
    Agreement) to occur.

        (t) Effectiveness of Waiver. The Company has waived the Company's rights
    under the Stock Purchase Agreement, dated as of September 24, 1991, between
    the Company and Anasco GmbH (the "Anasco Stock Purchase Agreement") so that
    Anasco GmbH's execution or delivery of the Stockholders Agreement and its
    consummation of the transactions contemplated by the Stockholders Agreement,
    will not violate or breach any provision in the Anasco Stock Purchase
    Agreement.

        (u) Opinion of the Company's Financial Advisor. The Board of Directors
    of the Company has received a written opinion from Alex. Brown & Sons
    Incorporated ("Alex Brown") to the effect that, as of the date of this
    Agreement, the consideration to be received in the Offer and the Merger by
    the holders of Shares (other than Parent and its affiliates) is fair from a
    financial point of view to such holders of Shares.

        (v) No Other Representations or Warranties. Except for the
    representations and warranties contained in this Section 3.2, neither the
    Company nor any other Person makes any other express or implied
    representation or warranty on behalf of the Company or any of its
    affiliates.


                                  4. COVENANTS

        4.1 Acquisition Transactions. (a) After the date hereof and prior to the
Effective Time or earlier termination of this Agreement, unless Parent shall
otherwise agree in writing, the Company shall not, shall not permit any of its
subsidiaries to, and shall not authorize or permit any officer, director or
employee or any investment banker, attorney, accountant or other advisor or
representative of the Company or any of its subsidiaries to, directly or
indirectly, except as otherwise expressly permitted in this Section 4.1(a) or in
Section 4.1(b), (i) initiate, solicit, negotiate, encourage, or provide
confidential information to facilitate any proposal or offer to acquire all or
any substantial part of the business and properties of the Company and its
subsidiaries, taken as a whole, or beneficial ownership (as determined pursuant
to Rule 13d-3 promulgated under the Exchange Act) of 20% or more of the capital
stock of the Company, whether by merger, purchase of assets, tender offer or
otherwise, whether


                                       22
<PAGE>   26
for cash, securities or any other consideration or combination thereof (such
transactions being referred to herein as "Acquisition Transactions"), (ii) enter
into any agreement with respect to any Acquisition Transaction or give any
approval of the type referred to in Section 4.1(b) with respect to any
Acquisition Transaction or (iii) participate in any discussions regarding, or
take any other action to facilitate any inquiries or the making of any proposal
that constitutes or may reasonably be expected to lead to any Acquisition
Transaction. Notwithstanding the immediately preceding sentence, the Company and
its subsidiaries may, prior to the Company Stockholder Approval, in response to
any unsolicited proposal for an Acquisition Transaction, furnish information
concerning its business, properties or assets to the corporation, partnership,
person or other entity or group (a "Potential Acquiror") making such proposal
for an Acquisition Transaction and participate in negotiations with the
Potential Acquiror if (x) the Company's Board of Directors, after consultation
with one or more of its independent financial advisors, is of the reasonable
belief that such Potential Acquiror has the financial wherewithal to consummate
such an Acquisition Transaction, (y) the Company's Board of Directors reasonably
determines, after receiving advice from the Company's financial advisor, that
such Potential Acquiror has submitted a proposal for an Acquisition Transaction
that involves consideration to the Company's stockholders and other terms that
taken as a whole are superior to the Merger, and (z) based upon advice of
counsel to such effect, the Company's Board of Directors determines in good
faith that it is necessary to so furnish information and negotiate in order to
comply with its fiduciary duty to stockholders of the Company. In the event the
Company shall determine to provide any information as described above or shall
receive any offer of the type referred to in this Section 4.1 or shall receive
or become aware of any other proposal to acquire a substantial part of the
business and properties of the Company and its subsidiaries, taken as a whole,
or to acquire a substantial amount of capital stock of the Company, it shall
promptly inform Parent orally as to the fact that information is to be provided
and shall furnish to Parent the identity of the recipient of such information
and/or the proponent of any such offer or proposal and a description of the
material terms thereof. The Company will keep Parent fully informed of the
status and material details of any proposed Acquisition Transaction or other
transaction (including any material amendments or material proposed amendments
of any such proposed Acquisition Transaction or other transaction).

        (b) Neither the Board of Directors of the Company nor any committee
thereof (x) shall withdraw or modify or propose to withdraw or modify, in any
manner adverse to Parent the approval of recommendation of such Board of
Directors or such committee of this Agreement, the Offer or the Merger or (y)
approve or recommend, or propose to approve or recommend, any proposal for an
Acquisition Transaction except, in each case, in connection with a Superior
Proposal (as defined in Section 6.5).

        distributions in respect of, any of its capital stock, other than

        subsidiary of the Company to its parent, (y) split, combine or
        reclassify any of its capital stock or issue or authorize the issuance
        of any other securities in respect of, in lieu of or in substitution for
        shares of its capital stock or (z) purchase, redeem or otherwise acquire
        any shares of capital stock of the Company or any of its subsidiaries or
        any other securities thereof or any rights, warrants or options to
        acquire any such shares or other securities;

           (ii) issue, deliver, sell, pledge or otherwise encumber any shares of
        its capital stock, any other voting securities or any securities
        convertible into, or any rights, warrants or options to acquire, any
        such shares, voting securities or convertible securities, except upon
        exercise of any Option;

           (iii) amend its certificate of incorporation, by-laws or other
        comparable organizational documents;

           (iv) except as set forth on the Disclosure Schedule, acquire or agree
        to acquire (x) by merging or consolidating with, or by purchasing a
        substantial portion of the assets of, or by any other manner, any
        business or any corporation, limited liability company, partnership,
        joint venture, association or other business organization or division
        thereof or (y) any assets that individually or in the aggregate are
        material to the Company and its subsidiaries taken as a whole;

           (v) except as set forth on the Disclosure Schedule, sell, lease,
        license, mortgage or otherwise encumber or subject to any Lien or
        otherwise dispose of any of its properties or assets, other than in the

        capital purposes not in excess of $500,000 at any one time outstanding
        incurred in the ordinary course of business consistent with past
        practice and except for inter- 


                                       24

        company indebtedness between the Company and any of its wholly-owned
        subsidiaries or between such wholly-owned subsidiaries, or make any
        loans, advances or capital contributions to, or investments in, any
        other person, other than to the Company or any direct or indirect wholly
        owned subsidiary of the Company;

           (vii) except as set forth on the Disclosure Schedule, make or agree
        to make any new capital expenditure or capital expenditures which in the
        aggregate are in excess of $250,000;

           (viii) make any tax election that could reasonably be expected to
        have a Material Adverse Effect on the Company or settle or compromise
        any material income tax liability;

           (ix) except in the ordinary course of business or except as would not
        reasonably be expected to have a Material Adverse Effect on the Company
        or except as set forth on the Disclosure Schedule, modify, amend or
        terminate any material contract or agreement to which the Company or any
        subsidiary is a party or waive, release or assign any material rights or
        claims thereunder;

           (x) make any material change to its accounting methods, principles or
        practices, except as may be required by generally accepted accounting
        principles or as disclosed in the Disclosure Schedule;

           (xi) permit any amendment to the form of benefit payments elected on
        February 16, 1996 pursuant to the BioWhittaker, Inc. Supplemental
        Executive Retirement Plan Deferral Agreement by any participant; or

           (xii) authorize, or commit or agree to take, any of the foregoing
        actions.

        (b) Other Actions. Except as expressly permitted by Section 4.1, the
    Company shall not, and shall not permit any of its subsidiaries to, take any
    action that would, or that could reasonably be expected to, result in (i)
    any of the representations and warranties of the Company set forth in this
    Agreement that are qualified as to materiality becoming untrue, (ii) any of
    such representations and warranties that are not so qualified becoming
    untrue in any respect or (iii) any of the conditions to the Merger set forth
    in Article 5 not being satisfied.

        (c) Advice of Changes. The Company shall promptly advise Parent and
    Parent shall promptly advise the Company orally and in writing of (i) any
    repre- 


                                       25
<PAGE>   29
    sentation or warranty made by it (or, in the case of Parent, made by it or
    the Purchaser) contained in this Agreement that is qualified as to
    materiality becoming untrue or inaccurate in any respect or any such
    representation or warranty that is not so qualified becoming untrue or
    inaccurate in any respect or (ii) the failure by it (or, in the case of
    Parent, a failure by it or the Purchaser) to comply with or satisfy in any
    material respect any covenant, condition or agreement to be complied with or
    satisfied by it under this Agreement, provided, however, that no such
    notification shall affect the representations, warranties, covenants or
    agreements of the parties or the conditions to the obligations of the
    parties under this Agreement.

        4.3 Access and Information. Throughout the period prior to the Effective
Time, so long as this Agreement remains in effect, the Company shall afford to
the Purchaser and its representatives such access, during normal business hours,
to the Company's and its subsidiaries' books, records (including, without
limitation, tax returns and work papers of the Company's independent auditors),
plant and personnel, and to such other information, as Parent shall reasonably
request. Parent and the Purchaser will treat, and will cause their respective
accountants, counsel and other representatives to treat, as strictly
confidential all non-public documents and non-public information concerning the
Company furnished to Parent or the Purchaser in connection with the
transactions contemplated by this Agreement, subject to the requirements of law
and the provisions of this Agreement. If the transactions contemplated by this
Agreement are not consummated, such confidence shall be maintained except to the
extent such information can be shown to have been (i) in the public domain
through no fault of Parent or the Purchaser or (ii) later lawfully acquired by
Parent or the Purchaser from other sources without any breach of duty to the
Company by Parent, the Purchaser or, to the knowledge of Parent or the
Purchaser, any third party. If requested by the Company, Parent and the
Purchaser will return to the Company all copies of written information furnished
by the Company to Parent or the Purchaser or its agents, representatives or
advisors.

        4.4 Certain Filings, Consents and Arrangements. Parent, the Purchaser
and the Company shall use their reasonable best efforts to make promptly any
required submissions under the HSR Act with respect to the Merger and the
transactions contemplated by this Agreement. The Company shall use its
reasonable best efforts to obtain all consents, approvals, permits or
authorizations as are required to be obtained from other parties to loan
agreements or other contracts material to the Company's business in connection
with the consummation of the Merger.

        4.5 Reasonable Best Efforts. (a) Subject to the terms and conditions
provided in this Agreement, each of the parties agrees to use its reasonable
best efforts to take


                                       26
<PAGE>   30
promptly, or cause to be taken, all actions and to do promptly, or cause to be
done, all things necessary, proper or advisable to consummate and make effective
the transactions contemplated by this Agreement, including using its reasonable
best efforts (i) to obtain all necessary waivers, consents and approvals, and
(ii) to effect all necessary registrations and filings, subject, however, to
Company Stockholder Approval (as defined in Section 4.7 hereof). In case at any
time after the Effective Time any further action is necessary or desirable to
carry out the obligations of the parties under this Agreement, the proper
officers and/or directors of Parent, the Purchaser and the Company, as the case
may be, shall take the necessary action.

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

        4.6 Public Statements. So long as this Agreement remains in effect,
Parent and the Purchaser, on the one hand, and the Company, on the other hand,
will consult with each other before issuing, and provide each other the
opportunity to review, comment upon and concur with, any press release or other
public statements with respect to the transactions contemplated by this
Agreement, including the Offer and the Merger, and shall not issue any such
press release or make any such public statement prior to such consultation,
except as may be required by applicable law, court process or by obligations
pursuant to any listing agreement with any national securities exchange.

        4.7 Stockholder Approval. (a) If required by applicable law in order to
consummate the Merger, as soon as practicable following the purchase of the
Shares pursuant to the Offer, the Company shall duly call, give notice of,
convene and hold a meeting of its stockholders (the "Company Stockholders
Meeting") for the purpose of adopting and approving this Agreement and the
transactions contemplated hereby (the


                                       27
<PAGE>   31
"Company Stockholder Approval"). Without limiting the generality of the
foregoing, the Company agrees that its obligations pursuant to the first
sentence of this Section 4.7(a) shall not be affected by the commencement,
public proposal, public disclosure or communication to the Company of any
proposed Acquisition Transaction. The Company will, through its Board of
Directors, recommend to its stockholders the approval and adoption of this
Agreement and the transactions contemplated hereby, except to the extent that
the Board of Directors of the Company shall have withdrawn or modified its
approval or recommendation of this Agreement or the Merger and terminated this
Agreement in accordance with Section 4.1(b). At such meeting, the Parent and the
Purchaser will each vote, or cause to be voted, all Shares acquired in the Offer
or otherwise beneficially owned by it or any of its subsidiaries on the record
date for such meeting, in favor of the approval and adoption of this Agreement
and the transactions contemplated hereby.

        (b) The Company shall, if required by law, prepare and file a proxy
statement (the "Proxy Statement") with the Commission in connection with
obtaining the Company Stockholder Approval. Parent and the Purchaser shall
cooperate with the Company in the preparation of the Proxy Statement including,
without limitation, promptly providing information requested by the Company or
required by the Commission to be included in the Proxy Statement and responding
promptly to any inquiries from the Company made in connection with comments on
the Proxy Statement received from the Commission. The Company will use its
reasonable best efforts to cause the Proxy Statement to be mailed to the
Company's stockholders as promptly as practicable after the Commission completes
its review of the Proxy Statement.

        (c) The Company agrees that none of the information included or
incorporated by reference in the Proxy Statement or otherwise supplied by the
Company to its stockholders, including any amendments to any of the foregoing,
will be false or misleading with respect to any material fact or will omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading; provided, that the foregoing shall not apply to
information supplied by or on behalf of Parent or the Purchaser specifically for
inclusion or incorporation by reference in any such document. Parent agrees that
none of the information supplied by or on behalf of Parent or the Purchaser
specifically for inclusion or incorporation by reference in any such document
will be false or misleading with respect to any material fact or will omit to
state any material fact required to be stated therein or necessary in order to
make the statements in such information, in light of the circumstances under
which they are made, not misleading.


                                       28
<PAGE>   32
        (d) Notwithstanding the foregoing, in the event that the Purchaser shall
acquire at least 90 percent of the outstanding Shares, the parties hereto agree,
at the request of the Parent or the Purchaser, to take all necessary and
appropriate action to cause the Merger to become effective, as soon as
practicable after the expiration of the Offer, without a meeting of stockholders
of the Company, in accordance with Section 253 of the DGCL.

        4.8 Stockholder Litigation. The Company shall consult with the Parent
regarding the defense or settlement of any stockholder litigation against the
Company and its directors relating to the transactions contemplated by this
Agreement; it being understood that the Company shall be entitled to control and
conduct any such litigation.

        4.9 Indemnification, Exculpation and Insurance. Parent and the Purchaser
agree that all rights to indemnification and exculpation from liabilities for
acts or omissions occurring at or prior to the Effective Time now existing in
favor of the current or former directors or officers of the Company and its
subsidiaries as provided in their respective certificates of incorporation,
by-laws (or comparable organizational documents) and indemnification agreements
shall survive the Merger and shall continue in full force and effect in
accordance with their terms for a period of not less than six years from the
Effective Time. Parent will cause to be maintained for a period of not less than
six years from the Effective Time the Company's current directors' and officers'
insurance and indemnification policy to the extent that it provides coverage for
events occurring prior to the Effective Time ("D&O Insurance") for all persons
who are directors and officers of the Company on the date of this Agreement, so
long as the annual premium therefor would not be in excess of 200% of the last
annual premium paid prior to the date of this Agreement (the "Maximum Premium");
provided, however, that Parent may, in lieu of maintaining such existing D&O
Insurance as provided above, cause coverage to be provided under any policy
maintained for the benefit of Parent or any of its subsidiaries or any policy
specifically obtained for this purpose, so long as the terms thereof are no less
advantageous to the intended beneficiaries thereof than the existing D&O
Insurance. If the existing D&O Insurance expires, is terminated or canceled
during such six-year period, Parent will use all reasonable efforts to cause to
be obtained as much D&O Insurance as can be obtained for the remainder of such
period for an annualized premium not in excess of the Maximum Premium, on terms
and conditions no less advantageous to the covered persons than the existing D&O
Insurance. The Company represents to Parent that the Maximum Premium is
$340,000.

        4.10 Amendment of Rights Agreement. The Company covenants and agrees
that it will not take action pursuant to or amend the Rights Agreement or redeem
the Rights or terminate the Rights Agreement prior to the Effective Time, except
as expressly contemplated or permitted by Section 3.1(s) of this Agreement.

        4.11 Borrowings under the Loan Agreement. The Company shall consult with
the Parent prior to electing any new interest rate for any interest period under
the Loan Agreement with Nationsbank identified in the Disclosure Schedule and
shall otherwise manage its obligations thereunder to insure that neither the
Company, the Parent nor the Purchaser shall incur any breakage or similar
prepayment costs in the event the Company prepays its outstanding indebtedness
thereunder at the Effective Time.


                                  5. CONDITIONS

    of the Offer or of this Agreement.

        (b) The consummation of the Merger shall not be precluded by any order,
    decree or injunction of a court of competent jurisdiction (each party
    agreeing to use its best efforts to have any such order reversed or
    injunction lifted), and there shall not have been any action taken or any
    Law enacted, promulgated or deemed applicable to the Merger by any
    Governmental Entity that makes consummation of the Merger illegal.

        (c) If required by Certificate of Incorporation and By-Laws of the
    Company and the DGCL, this Agreement shall have been approved and adopted by
    the affirmative vote of the holders of the requisite number of shares of

        (c) The 179,656 Shares previously held by the Trust shall have been

                                6. MISCELLANEOUS

        6.1 Termination. This Agreement may be terminated and the Merger contem-
plated herein may be abandoned at any time prior to the Effective Time, whether
prior to or after approval by the stockholders of the Company:

        (a) by the mutual written consent of Parent, the Purchaser and the
Company;

        (b) by either the Parent or the Company if, on or before October 31,
        1997 and without fault of such terminating party, Purchaser shall not
        have purchased in the Offer such number of the Shares which, together
        with the number of Option Shares (as such term is defined in the
        Stockholder Agreement) subject to the Stockholder Agreement, represent
        in excess of 50% of the Shares on a fully diluted basis, or the Merger
        shall not have been consummated on or before November 30, 1997, provided
        however, that the right to terminate this Agreement shall not be
        available (i) to any party whose failure to fulfill any obligation under
        this Agreement has been the cause of, or resulted in, the failure of the
        Offer or the Merger to have occurred on or before the aforesaid date;

        (c) by either the Parent or the Company if the Offer shall expire or
        terminate in accordance with its terms without any Shares having been
        purchased thereunder and, in the case of termination by the Parent, the
        Purchaser shall not have been required by the terms of the Offer or this
        Agreement to purchase any Shares pursuant to the Offer;

        (d) by the Company if the Purchaser shall not timely commence the Offer
        as provided in Section 1.1(a);

        (e) if a Company Stockholder Approval is required by law, by either the
        Purchaser or the Company if, upon a vote at a duly held Company Stock-
        holders Meeting or any adjournment thereof at which such Company Stock-
        holder Approval shall have been voted upon, such Company Stockholder
        Approval shall not have been obtained;

        (f) unilaterally by the Purchaser or the Company (i) if the other fails
        to perform any material covenant or agreement in any material respect in
        this Agreement, and does not cure the failure in all material respects
        within 30 business days after the terminating party delivers written
        notice of the alleged


                                       32
<PAGE>   36
        failure or (ii) if any condition to the obligations of that party is not
        satisfied (other than by reason of a breach by that party of its
        obligations hereunder), and it reasonably appears that the condition
        cannot be satisfied prior to November 30, 1997;

        (g) by either the Purchaser or the Company if either is prohibited by an
        order or injunction (other than an order or injunction on a temporary or
        preliminary basis) of a court of competent jurisdiction or other
        Governmental Entity from consummating the Offer or the Merger and all
        means of appeal and all appeals from such order or injunction have been
        finally exhausted;

        (h) by the Purchaser if the Board of Directors of the Company shall have
        withdrawn or modified, or resolved to withdraw or modify, in any manner
        which is adverse to Parent or the Purchaser, its recommendation or
        approval of the Merger or this Agreement; provided, however, that a
        termination pursuant to this Section shall not become effective if, as a
        result of the Company's receipt of a proposal for an Acquisition
        Transaction from a third party, the Company, in accordance with Section
        4.1(b), withdraws or modifies, or resolves to withdraw or modify, in any
        manner which is adverse to Parent or the Purchaser, its recommendation
        or approval of the Offer, the Merger or this Agreement and if within ten
        business days of taking and disclosing to its stockholders the
        aforementioned position the Company publicly reconfirms its
        recommendation of the transactions contemplated hereby; or

        (i) by the Company if (i) the Board of Directors of the Company shall
        have determined in good faith, based on the advice of outside counsel,
        that it is necessary, in order to comply with its fiduciary duties to
        the Company's stockholders under applicable law, to terminate this
        Agreement to enter into an agreement with respect to or to consummate a
        transaction constituting a Superior Proposal (as defined in Section
        6.5), (ii) the Company shall have given notice to the Purchaser advising
        the Purchaser that the Company has received a Superior Proposal from a
        third party, specifying the material terms and conditions (including the
        identity of the third party), and that the Company intends to terminate
        this Agreement in accordance with this Section 6.1(i), (iii) either (A)
        the Purchaser shall not have revised its proposal for an Acquisition
        Transaction within two business days from the time on which such notice
        is deemed to have been given to Parent, or (B) if the Purchaser within
        such period shall have revised its proposal for an Acquisition
        Transaction, the Board of Directors of the Company, after receiving
        advice from the Company's financial advisor, shall have determined in
        its good faith reasonable


                                       33
<PAGE>   37
        judgment that the third party's proposal for an Acquisition Transaction
        is superior to Parent's revised proposal for an Acquisition Transaction,
        and (iv) the Company, at the time of such termination, pays the Expenses
        and the Termination Fee in accordance with Section 6.12.

    In the event of a termination of this Agreement and an abandonment of the
    Merger, no party hereto (or any of its directors, officers, representatives
    or agents) shall have any further liability or further obligation to any
    other party to this Agreement, except with respect to the provisions of this
    Article 6 and the other provisions that survive the Merger pursuant to
    Section 6.2 and except that nothing herein will relieve any party from
    liability for any willful breach of its representations, warranties,
    covenants and agreements set forth in this Agreement.

        6.2 Non-Survival of Representations, Warranties and Agreements. The
representations, warranties and agreements in this Agreement shall terminate at
the Effective Time or the termination of this Agreement pursuant to Section 6.1,
as the case may be, except that, in the event the Effective Time occurs, the
agreements set forth in Section 4.9 and the last sentence of Section 4.5(a)
shall survive indefinitely and, in the event this Agreement is terminated prior
to the occurrence of the Effective Time, the agreements set forth in Sections
4.3 and 6.12 shall survive indefinitely.

        6.3 Amendment and Waiver. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto and in
compliance with applicable law. At any time prior to the Effective Time, the
parties hereto may (a) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant thereto and (c) waive compliance with any of the
agreements or conditions contained herein; provided, however, that no such
waiver may materially adversely affect the rights of the stockholders of the
Company. Any agreement on the part of a party hereto to any such extension or
waiver shall be valid if set forth in an instrument in writing signed on behalf
of such party.

        6.4 Entire Agreement. This Agreement and the two separate but
substantially identical Stockholder Agreements, each dated as of the date,
hereof among Parent and certain stockholders of the Company and the
Confidentiality Agreement dated as of March 20, 1997, between the Company and
Parent contain the entire agreement among Parent, the Purchaser and the Company
with respect to the Merger and the other transactions contemplated hereby and
thereby, and such agreements supersede all prior agreements among the parties
with respect to these matters.

        6.9 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute but one agreement.

        6.10 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this

                                       36
<PAGE>   40
enforceability of any of the terms or provisions of this Agreement in any other
jurisdiction. If any provision of this Agreement is so broad as to be

        6.11 Parties in Interest; Assignment. This Agreement is binding upon and
is solely for the benefit of the parties hereto and their respective successors,

parties. The Purchaser shall have the right (a) to assign to Parent or any
direct or indirect wholly-owned subsidiary of Parent any and all rights and
obligations of the Purchaser under this Agreement, including, without
limitation, the right to substitute in its place such a subsidiary as one of the
constituent corporations in the Merger (such subsidiary assuming all of the
obligations of the Purchaser in connection with the Merger) and may require
subsidiaries of the Company to merge with subsidiaries of the Purchaser (or its
assignees) in connection with the Merger and (b) to restructure the transaction
to provide for the merger of the Company with and into the Purchaser or such
other entity as provided above; provided, however, that the Company shall not be
deemed to have breached any of its representations and warranties herein by
reason of the Purchaser exercising its rights hereunder, and by exercising such
rights Parent will be deemed to have waived the receipt of any additional
consents of third parties required by virtue thereof; and provided further that
no such assignment shall affect any obligation of Parent or Purchaser hereunder
and that it shall remain primarily liable as to its assigned obligations. If the
Purchaser exercises its right to so restructure the transaction, the Company
shall promptly enter into appropriate agreements to reflect such restructuring.

        6.12 Fees and Expenses. (a) Except as provided below in this Section
6.12, all fees and expenses incurred in connection with the Offer, the Merger,
this Agreement, the Stockholder Agreement and the transactions contemplated by
this Agreement and the Stockholder Agreement shall be paid by the party
incurring such fees or expenses, whether or not the Merger is consummated.

        (b) The Company shall pay, or cause to be paid, in same day funds to
Parent the sum of (x) Parent's Expenses (as defined below) and (y) $4,125,000
(the "Termination Fee") upon demand if the Company terminates this Agreement
pursuant to Section 6.1(i). In addition, the Company shall pay or cause to be
paid, in same day funds to Parent the sum of Parent's Expenses and the
Termination Fee if (i) the Purchaser terminates this Agreement pursuant to
Section 6.1(f) or 6.1(h) at any time after a proposal for an Acquisition
Transaction has been made (ii) the Company or the Purchaser terminates this
Agreement pursuant to Section 6.1(b), 6.1(c) or 6.1(e) at any time after a
proposal for an Acquisition Transaction has been made or (iii) the


                                       37
<PAGE>   41
Purchaser terminates this Agreement pursuant to Section 6.1(f)(ii) at any time
after a proposal for an Acquisition Transaction has been made and, within nine
months after any termination referred to in the immediately preceding clauses
(i), (ii) or (iii) of this sentence, the Person that made the proposal for an
Acquisition Transaction (or an affiliate thereof) completes a merger,
consolidation or other business combination with the Company or a subsidiary of
the Company, or the purchase from the Company or from a subsidiary of the

         affect (or materially delay) the consummation of the Offer or (v) in
         the case of any of the foregoing existing at the time of the execution
         of the Agreement, a material acceleration or worsening thereof which

         other than Parent or any of its affiliates, or (ii) (A) the Board of
         Directors of the Company or any committee thereof shall have withdrawn
         or modified in a manner adverse to Parent or Purchaser the approval or
         recommendation of the Offer, the Merger or the Agreement and, within
         ten business days of taking and disclosing to its stockholders the
         aforementioned position, shall not have publicly reconfirmed its
         recommendation of the Offer, the Merger or the Agreement, or approved

         other than the Offer and the Merger, (B) any such corporation,
         partnership, person or other entity or group shall have entered into a
         definitive agreement or an agreement in principle with the Company with

         foregoing;

                  (d) any of the representations and warranties of the Company
         set forth in the Agreement that are qualified as to materiality shall
         not be true and correct or any such representations and warranties that
         are not so qualified shall not be true and correct in any material
         respect, in each case as if such representations and warranties were
         made at the time of such determination, except with respect to
         representations and warranties made as of an earlier time;

                  (e) the Company shall have failed to perform any material
         obligation or to comply with any material agreement or material

         the Agreement;

                  (f) the Agreement shall have been terminated in accordance
         with its terms or the Offer shall have been terminated with the consent

                  (g) any waiting periods under the HSR Act applicable to the

<PAGE>   46


         Company or Parent, directly or indirectly, has material assets or
         operations, shall not have been obtained and such failure to obtain
         could reasonably be expected to have a Material Adverse Effect on the
         Company or the value of the Shares or the Offer to the Purchaser;

which, in the good faith sole judgment of Purchaser makes it inadvisable to
proceed with the Offer or with such acceptance for payment of or payment for
Shares or to proceed with the Merger.

         The foregoing conditions are for the sole benefit of Purchaser and may
be asserted by Purchaser regardless of the circumstances giving rise to any such
condition or may be waived by Purchaser in whole or in part at any time and from
time to time in its sole discretion (subject to the terms of the Agreement). The
failure by Purchaser at any time to exercise any of the foregoing rights shall
not be deemed a waiver of any such right, the waiver of any such right with
respect to particular facts and other circumstances shall not be deemed a waiver
with respect to any other facts and circumstances, and each such right shall be
deemed an ongoing right that may be asserted at any time and from time to time.

                  cease to be in effect (see Section 9.1 of the 1995 SPA).

                           The covenants of Section 9.2(b) of the SPA would
                  become effective. In addition, and depending on whether the

                  covenants of Section (9.2(a), (c) and (d) may also become
                  effective.

                  -    George Erie
                       v.
                       BioWhittaker, Inc., Noel Buterbaugh and Thomas R. Winkler
                       United States District Court
                       District of Massachusetts
                       Civil Action No. 97-11414 REK

                       George Erie was formerly employed by BioWhittaker as
                       a salesman. On May 22, 1997, Mr. Erie's employment
                       was terminated by BioWhittaker. Mr. Erie has filed
                       suit claiming damages for (a) breach of contract (an
                       alleged lifetime employment contract), (b) promissory
                       estoppel (based on a representation that the Company
                       would employ Mr. Erie until he chose to retire) and
                       (c) negligent or intentional misrepresentation
                       (inducing Mr. Erie to leave his prior employment).


                       Mr. Erie seeks damages in an undetermined amount, but
                       indicates that the compensation that he would have
                       earned from continued employment would have been not
                       less than $1,585,000. Mr. Erie also seeks interest and
                       costs, including reasonable attorney's fees.

                       At this time, the Company has not been required to
                       file a response to the original complaint. The
                       Company will contend that, in addition to other
                       defenses, Mr. Erie was employed at will.

                       Civil Action No. 3:CV-96-0608

                       Mr. Bardsley was, at one time, an employee of PRTB
                       and/or its subsidiaries. Mr. Bardsley left PRTB's
                       employ and set up Anatomic Gift Foundation and the
                       Human Cell Culture Center, Inc. (HCCC) in 1994 or
                       before. PRTB claims that the defendants (a) usurped a
                       corporate opportunity (b) converted and
                       misappropriated trade secrets


                                        4


<PAGE>   53


         (c) conspired to harm PRTB and other defendants, (d) breached
         agreements with PRTB and its subsidiaries, (e) breached their fiduciary
         duty to PRTB and its subsidiaries and (f) tortiously interfered with
         contractual relationships with organ procurement organizations,
         researchers and others.

         In the complaint, the plaintiff seeks unspecified damages in excess of
         $50,000 and punitive damages together with interest and costs and
         injunctions to prevent further violations of plaintiff's rights. In
         1996, BioWhittaker entered into a contract with HCCC (a copy of which
         has been furnished to Parent) to distribute certain products for HCCC.
         In July of 1997, the plaintiff filed a motion to join BioWhittaker as a
         party to the litigation. Defendants have responded opposing the motion
         to join BioWhittaker. At this time, BioWhittaker is not a party to the
         suit and will have a chance to file motions objecting to its joinder,
         if plaintiff's motion to join BioWhittaker is approved by the court.

         Case No. Tokyo District Court Hei-9(1997)-WAS-5792
         Case No. Tokyo District Court Hei-9(1997)-YO-22042

         BioWhittaker previously sued Pharmacia AB (now merged with Upjohn as
         Pharmacia & Upjohn, Inc.) and certain of its affiliates (collectively
         with Pharmacia referred to as Pharmacia) and one of its distributors in
         the United States for breach of its U.S. Patent on methods for testing
         for certain allergies. After a partial summary judgment in favor of
         BioWhittaker, Pharmacia agreed to a settlement in which it agreed to
         pay $3.5 million in damages for past infringement, $500,000 as a
         royalty for 1995 and royalties at a rate of 3% per annum for all sales
         in the United States, Canada and Australia until BioWhittaker's patents
         in those countries expired, with a minimum royalty of $300,000 per year
         on sales from the United States for years 1996-1999.

         At the time of the US settlement, there was a patent pending on the
         same technology in Japan. Pharmacia chose to oppose the issuance of
         that patent, but the Patent was issued over Pharmacia's opposition. Now
         that the patent has issued in Japan, after unsuccessful attempts to get
         Pharmacia to negotiate concerning use of the patented technology in
         Japan, the Company has filed a lawsuit against Pharmaria seeking
         damages and an injunction against future use of the patent. The amount
         of the controversy is approximately 7.5 billion yen, including
         approximately 5 billion yen of damages and compensation and
         approximately 2.5 billion yen representing the value of the injunctions
         against Pharmacia and one of its Japanese distributors.

         la 2 ieme Chambre du Tribunal de Grande Instance de Rennes, France
         Case No. 3282/95

         These cases began prior to BioWhittaker's acquisition of Clonetics
         Corporation. Originally Messrs. Hinz and Huttner, trading as PromoCell
         filed suit in Germany against a Clonetics distributor and Clonetics
         Corporation seeking damages for trademark infringement. It was
         subsequently determined that Messrs. Hinz and Huttner had trademarked
         marks which were already in use by Clonetics and copied Clonetics
         promotional materials. Clonetics countersued for unfair trade practices
         and other causes of action seeking a cancellation of PromoCell's
         trademarks that copied the Clonetics trademarks, damages and other
         remedies. In the original trial court, Clonetics was awarded damages,
         the cancellation of the infringing marks and other remedies. On appeal,
         the intermediate court confirmed in part and reversed in part,
         indicating that Clonetics was entitled to cancellation of the marks
         registered by PromoCell, but was not entitled to damages. The matter is
         presently on appeal to the highest court in Germany and is awaiting the
         original trial in France where Clonetics had filed trademarks prior to
         PromoCell's use of similar marks.

                  1997 from Marjorie Hunter, Technology Licensing Specialist
                  with the Centers for Disease Control and Prevention,
                  indicating that BioWhittaker was marketing H292 Human Lung
                  Mucocpidermoid Carcinoma Cells and alleging that the cells
                  were subject to a patent issued on November 16, 1993 relating
                  to methods for propagating human paramyxoviruses in the H292
                  cell line. She further indicated that the patent had been
                  exclusively licensed to Intracel Corporation. BioWhittaker is
                  in the process of investigating this claim. However, total
                  sales of the product alleged to infringe the patent have not
                  exceeded $20,000 in total for the period of four years since
                  the patent was issued.

      Cambrex also announced that BW Acquisition Corporation intends to merge
