FORWARD-LOOKING STATEMENTS.

     In connection with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995 (the "Reform Act"), NetOptix Corporation,
previously Galileo Corporation, a Delaware corporation (the "Registrant"), is
hereby providing cautionary statements identifying important factors that could
cause the Registrant's actual results to differ materially from those projected
in forward-looking statements (as such term is defined in the Reform Act) made
by or on behalf of the Registrant herein or orally, whether in presentations, in
response to questions or otherwise. Any statements that express, or involve
discussions as to, expectations, beliefs, plans, objectives, assumptions or
future events or performance (often, but not always, identified through the use
of words or phrases such as the Registrant or management "believes," "expects,"
"anticipates," "hopes"; words or phrases such as "will result," "are expected
to," "will continue," "is anticipated," "estimated," "projection," and
"outlook"; and words of similar import) are not historical facts and may be
forward-looking. Such forward-looking statements involve estimates, assumptions,
and uncertainties and, accordingly, actual results could differ materially from
those expressed in the forward-looking statements.

     Any forward-looking statement speaks only as of the date on which such
statement is made, and the Registrant undertakes no obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the date on which such statement is made or to reflect the occurrence of
unanticipated events.

Item 5.  Other Events.

CHANGE IN REGISTRANT NAME.

     The Registrant changed its name to NetOptix Corporation effective September
30, 1999. The Registrant's new Nasdaq trading symbol is OPTX. The name change
was made in recognition of the emergence of the Registrant primarily as a
manufacturer of optical telecommunications components and its focus on
developing and manufacturing Dense Wavelength Division Multiplex (DWDM) optical
filters.

DEBT FINANCING.

     On October 4, 1999, the Registrant announced that it had completed
arrangements for a debt financing package totaling $25,000,000 with Deutsche
Financial Services Corporation, a unit of Deutsche Bank Group. This package
consists of a $12,000,000 five-year revolving credit facility and a $13,000,000
five-year equipment acquisition facility secured by the Registrant's assets.

     This debt refinancing is part of the Registrant's plan to pay off its
existing bank debts, to finance the expansion of its manufacturing capacity for
DWDM optical filters at its Optical Filter Corporation (OFC) facility in Natick,
Massachusetts, to fund the previously announced start-up

of a new facility in Germany which will also manufacture DWDM optical filters
and to provide working capital.

aggregate unpaid principal amount of the Revolving Credit Loans then outstanding
exceeds the Borrowing Base (plus any Overadvance then permitted by the Agent in
its discretion under SECTION 3.7(d)), the U.S. Borrowers shall repay the
Revolving Credit Loans in an amount sufficient to reduce the aggregate unpaid
principal amount of such Loans by an amount equal to such excess, together with
accrued and unpaid interest on the amount repaid to the date of repayment; and
(c) the U.S. Borrowers hereby instruct the Agent to repay the Revolving Credit

<PAGE>   33


obligations in respect of all such Letter of Credit Guarantees then outstanding

     (b)  The U.S. Borrowers, jointly and severally, shall be absolutely and
unconditionally liable to reimburse the Agent on demand for any liability the

Commitment Percentage of the face amount thereof (including, without limitation,
all obligations of the U.S. Borrowers with respect thereto, other than amounts

guaranty pertaining thereto).

     (d)  In the event that the Agent makes a payment under any Letter of Credit
Guaranty and the Agent shall not have been repaid such amount pursuant to CLAUSE

amount of such payment, and notwithstanding the occurrence or continuance of a
Default or Event of Default at the time of such payment, such Non-Ratable Loan
shall be subject to the provisions of SECTION 3.8(c) and the absolute
obligations of the Lenders to pay for their respective participation interests
therein. Further, in the event any payment by or on behalf of any U.S. Borrower
with respect to any Letter of Credit Guaranty received by the Agent and
distributed by the Agent to the Lenders on account of their respective
participations therein is thereafter set aside, avoided or recovered from the
Agent in connection with any receivership, liquidation or bankruptcy proceeding,

contained therein, subject to the provisions of SECTION 3.5.

     Section 2B.2   MANNER OF BORROWING EQUIPMENT ACQUISITION LOANS. Borrowings
of the Equipment Acquisition Loans shall be made as follows:

     any Notice of Borrowing given or deemed given pursuant to this SECTION
     2B.2(a) by 12:00 noon on the proposed borrowing date (in the case of Prime
     Rate Equipment Acquisition Loans) or by 3:00 p.m. two Business Days before

     Alternate Currency in the case of German Acquisition Loans), an amount
     equal to such Lender's Commitment Percentage of such Prime Rate Equipment
     Acquisition Loan or LIBOR Equipment Acquisition Loan, as the case may be.

     (b)  DISBURSEMENT OF LOANS. Each Borrower hereby irrevocably authorizes the
Agent to disburse the proceeds of each borrowing requested pursuant to this
SECTION 2B.2 by wire transfer by the Agent in Dollars, in the case of U.S.
Equipment Acquisition Loans, and the Alternate Currency, in


                                      -29-

principal on the first day of each February, May, August and November
thereafter, based on a 5 year level amortization, and (ii) the outstanding
principal balance of all German Equipment Acquisition Loans shall be
consolidated, and such consolidated balance shall be due and payable, and shall
be repaid in full by the German Borrower in the Alternate Currency, in
consecutive quarterly installments of principal on the first day of each
February, May, August and November thereafter, based on a 5 year level
amortization.

     (c)  Notwithstanding anything herein to the contrary, all Equipment
Acquisition Loans shall be paid in full on the Termination Date.

     Section 2B.4   EQUIPMENT ACQUISITION NOTES. (a) Each Lender's U.S.

hereunder shall be irrevocable, and the amount to be prepaid (including accrued
interest and any prepayment fees) shall be due and payable on the date
designated in the notice.

     (b)  MANDATORY PREPAYMENTS.

          (i)  Any and all amounts received by the Borrowers as proceeds from
     the sale of any Equipment or Mortgaged Real Estate shall be paid,
     immediately upon receipt by the Borrowers, to the Agent, and shall be
     applied to the prepayment of the Equipment Acquisition Loans, unless, in
     the case of the proceeds from the sale of Equipment, such amounts are being
     used by the Borrowers within 30 days after receipt to acquire Equipment or
     Real Estate in the ordinary course of the Borrowers' business that will be
     subject to the Security Interest and unencumbered by any other Lien.

          (ii) Within 125 days after the end of each fiscal year of the
     Borrowers (commencing with the fiscal year ending on September 30, 2000),

     its chief financial officer demonstrating the calculation of the amount
     required to be paid.

          (iii) In the event that, at any time after the Effective Date, Parent
     or any of its Subsidiaries consummates a public offering of its stock, no
     later than the second Business Day following the date of receipt of the
     proceeds from such offering, the Borrowers shall (A) apply such proceeds,
     net of underwriting discounts and commissions and other reasonable fees,
     costs and expenses associated therewith, to the prepayment of the Equipment
     Acquisition Loans, and (B) the Borrowers' Agent shall deliver to the Agent
     a certificate of its chief financial officer demonstrating the calculations
     of the amount required to be paid.

          (iv) In connection with any sale or other disposition of the capital
     stock (or all or substantially all of the assets) of Leisegang pursuant to
     the terms of SECTION 10.7, Parent shall cause any net proceeds remaining
     after the prepayment in full of all outstanding Revolving Credit Loans in

     German Equipment Acquisition Loans in the inverse order of their
     maturities. Together with any such payment, the Borrowers shall pay all
     amounts due under SECTION 3.10 as a result of such prepayment. On the
     prepayment date, the Borrowers shall pay interest on the amount prepaid,
     accrued and unpaid to the prepayment date.

          (vi) The Borrowers shall also be obligated to prepay the Equipment
     Acquisition Loans in full together with accrued and unpaid interest thereon
     (and all amounts due under SECTION 3.10 as a result of such prepayment)
     upon any termination of this Agreement pursuant to SECTION 3.6 or otherwise
     or upon any acceleration of the Equipment Acquisition Loans pursuant to

     Section 3.1    INTEREST.


                                      -31-
<PAGE>   38


     (a)  PRIME RATE LOANS. Subject to the provisions of SECTION 3.1(d), the
U.S. Borrowers will pay interest on the unpaid principal amount of each Prime
Rate Revolving Credit Loan and each U.S. Equipment Acquisition Loan which is a
Prime Rate Loan, in each case for each day from the day such Loan is made until
such Loan is paid (whether at maturity, by reason of acceleration, or otherwise)
or is converted to a Loan of a different Type, at a rate per annum equal to the
sum of (i) the Applicable Margin and (ii) the Prime Rate, payable monthly in
arrears as it accrues on each Interest Payment Date and on the Termination Date.

     (b)  LIBOR LOANS. Subject to the provisions of SECTION 3.1(d), (i) the U.S.
Borrowers will pay interest on the unpaid principal amount of each LIBOR
Revolving Credit Loan and each U.S. Equipment Acquisition Loan which is a LIBOR
Loan, and (ii) the German Borrower will pay interest on the unpaid principal
amount of each German Equipment Acquisition Loan, in each case for the
applicable Interest Period at a rate per annum equal to the sum of (i) the
Applicable Margin and (ii) LIBOR, payable in arrears as it accrues on each
Interest Payment Date, and when such LIBOR Loan is due (whether at maturity, by
reason of acceleration or otherwise).

     (c)  OTHER OBLIGATIONS. The Borrowers will, to the extent permitted by
applicable law, pay interest on the unpaid principal amount of any Obligation
that is due and payable, other than the Loans, in accordance with SECTIONS
3.1(a) or (d), as applicable, as if such Obligation were a Prime Rate Revolving
Credit Loan.

     (d)  DEFAULT RATE. If there shall occur and be continuing an Event of
Default, at the election of the Required Lenders, the unpaid principal amount of
the Loans and other Obligations shall no longer bear interest in accordance with
the terms of SECTION 3.1(a), (b) or (c), but shall bear interest for each day
from the date of such Event of Default until such Event of Default shall have
been cured or waived at a rate per annum equal to the sum of (i) the Default
Margin and (ii) the rate otherwise applicable to such Loan or other Obligation,
payable on demand. The interest rate provided for in the preceding sentence
shall, to the extent permitted by applicable law, apply to and accrue on the
amount of any judgment entered with respect to any Obligation and shall continue
to accrue at such rate during any proceeding described in SECTION 11.1(g) or
(h).

     (e)  CALCULATION OF INTEREST. The interest rates provided for in SECTIONS
3.1(a), (b), (c) and (d) shall be computed on the basis of a year of 360 days
and the actual number of days elapsed.

     (f)  MAXIMUM RATE. It is not intended by the Lenders, and nothing contained
in this Agreement, any of the Notes or any other Loan Document shall be deemed,
to establish or require the payment of a rate of interest in excess of the
maximum rate permitted by applicable law (the "Maximum Rate"). In the event any
Lender receives, collects or applies as interest any sum in excess of the
Maximum Rate, such excess amount shall be applied to the reduction of the
principal balance of the applicable Obligation, and, if no such principal is
then outstanding, such excess or part thereof remaining shall be paid to the
Borrowers.

     Section 3.2    CERTAIN FEES.

     (a)  CLOSING FEE. As additional consideration for the extensions of credit
provided for hereunder, the Borrowers shall pay to the Agent, in addition to any
interest and other fees due under this Agreement, a closing fee as set forth in
the Fee Letter, such closing fee to be shared among the


                                      -32-
<PAGE>   39


Agent and the Lenders as set forth in separate written agreements among the
Agent and the Lenders. The closing fee provided for herein shall compensate the
Agent and the Lenders for the internal costs associated with the origination,
structuring, processing, approving and closing of the transactions contemplated
by this Agreement, including, but not limited to, administrative, general
overhead and lost opportunity costs, but not including any out-of-pocket
expenses for which the Borrowers have agreed to reimburse the Agent or any
Lender, including, without limitation, the Agent's out-of-pocket expenses
incurred in connection with its due diligence examination of the Borrowers and
the closing of the transactions contemplated by this Agreement. The closing fee
shall be fully earned on the Effective Date and shall not be subject to refund
or rebate.

     (b)  AGENT FEE. For administration and other services performed by the
Agent in connection with its continuing administration of this Agreement, the
Borrowers shall pay to the Agent, for its own account, an annual fee as set
forth in the Fee Letter, payable on the Effective Date and on each anniversary
of the Effective Date for so long as any Obligation shall remain outstanding or
the Revolving Credit Facility shall not have been terminated. The fee payable
pursuant to this SECTION 3.2(b) shall be fully earned by the Agent on the date
payment thereof is due and shall not be subject to refund or rebate.

     (c)  COMMITMENT FEE. In connection with and as consideration for the
holding available for the use of the U.S. Borrowers hereunder the full amount of
the Revolving Credit Facility, the U.S Borrowers will pay a fee to the Agent,
for the ratable benefit of the Lenders, for each day from the Effective Date
until the Termination Date, in an amount equal to 0.50% per annum of the unused
portion of the Revolving Credit Facility for such day. Such fee shall be payable
monthly in arrears on each Interest Payment Date and on the date of any
permanent reduction in the Revolving Credit Facility and shall be fully earned
when due and payable and shall not be subject to refund or rebate. Such fee is
not, and shall not be deemed to be, interest or a charge for the use of money.

     (d)  LETTER OF CREDIT FEES. The U. S. Borrowers agree to pay to the Agent
(i) for the ratable benefit of the Lenders, Letter of Credit fees equal to the
Applicable Margin from time to time applicable to LIBOR Revolving Credit Loans
based on the average daily aggregate face amount of all Letters of Credit from
time to time outstanding during the term of this Agreement, such fees to be due
and payable in arrears on the first day of each month, (ii) for the Agent's own
account, a facing fee of 0.375% of the face amount of each Letter of Credit,
such fee to be paid on the date of the issuance of each Letter of Credit, and
(iii) for the account of the Agent or the Issuing Bank, as the case may be, the
Issuing Bank's standard fees and charges with respect to the amendment,
processing, negotiation, renewal, and extension of letters of credit and
drawings thereunder.

     (e)  COLLECTION FEE. During the period from and including the Effective
Date to and including the Termination Date, the U.S. Borrowers will pay to the
Agent, for its own account, on the first day of each month an amount of interest
computed at the Effective Interest Rate applicable to Prime Rate Revolving
Credit Loans on each remittance (other than a remittance received via wire
transfer, automated clearinghouse transfer or otherwise in immediately available
funds) received by the Agent against Receivables (as contemplated by SECTION 7.1
hereof) during the preceding month, from the close of business on the date of
receipt of each such remittance until the close of business on the first
Business Day following the receipt of the remittance, as compensation for delays
in the collection and clearance of checks and other remittances.


                                      -33-
<PAGE>   40


     (f)  GENERAL. All fees shall be fully earned by the identified recipient
thereof when due and payable and, except as otherwise set forth herein or
required by applicable law, shall not be subject to refund or rebate. All fees
provided for in this SECTION 3.2 are for compensation for services and are not,
and shall not be deemed to be, interest or a charge for the use of money. All
fees under SECTIONS 3.2(c) and (d) shall be computed on the basis of a year of
360 days and the actual number of days elapsed.

     Section 3.3    MANNER OF PAYMENT. Except as otherwise expressly provided in
SECTION 7.1(b), each payment (including prepayments) by the Borrowers on account
of the principal of or interest on the Loans or of any other amounts payable to
the Lenders under this Agreement or any Note shall be made not later than 12:00
noon on the date specified for payment under this Agreement to the Agent, for
the account of the Lenders, at the Agent's Office, in the Alternate Currency, in
the case of any German Equipment Acquisition Loan, and in Dollars, in all other
cases, in immediately available funds, and shall be made without any setoff,
counterclaim or deduction whatsoever. Any payment received after such time but
before 1:00 p.m. on such day shall be deemed a payment on such date for the
purposes of SECTION 11.1, but for all other purposes shall be deemed to have
been made on the next succeeding Business Day.

     Section 3.4.   GENERAL. If any payment under this Agreement or any Note
shall be specified to be made upon a day which is not a Business Day, it shall
be made on the next succeeding day which is a Business Day and such extension of
time shall in such case be included in computing interest, if any, in accordance
with such payment.

     Section 3.5    LOAN ACCOUNTS; STATEMENTS OF ACCOUNTS.

     (a)  Each Lender shall open and maintain on its books a single loan account
in the Borrowers' name (each, a "Loan Account" and collectively, the "Loan
Accounts"). Each such Loan Account shall show as debits thereto each Loan made
under this Agreement by such Lender to the Borrowers and as credits thereto all
payments received by such Lender and applied to principal of such Loan, so that
the balance of the Loan Account at all times reflects the principal amount due
such Lender from the Borrowers.

     (b)  The Agent shall maintain on its books a single control account for the
Borrowers in which shall be recorded (i) the amount of each disbursement made
hereunder, (ii) the amount of any principal or interest due or to become due
from the Borrowers hereunder, and (iii) the amount of any sum received by the
Agent hereunder from the Borrowers and each Lender's ratable share therein.

     (c)  The entries made in the accounts pursuant to SUBSECTIONS (a) and (b)
shall be prima facie evidence, in the absence of manifest error, of the
existence and amounts of the obligations of the Borrowers therein recorded and
in case of discrepancy between such accounts, in the absence of manifest error,
the accounts maintained pursuant to SUBSECTION (b) shall be controlling.

     (d)  The Agent will account separately to the Borrowers' Agent monthly with
a statement of Loans, charges and payments made to and by the Borrowers pursuant
to this Agreement, and such accounts rendered by the Agent shall be deemed
final, binding and conclusive, save for manifest error, unless the Agent is
notified by the Borrowers' Agent in writing to the contrary within 30 days of
the date the account to the Borrowers' Agent was so rendered. Such notice by the
Borrowers' Agent shall


                                      -34-
<PAGE>   41


be deemed an objection to only those items specifically objected to therein.
Failure of the Agent to render such account shall in no way affect the rights of
the Agent or of the Lenders hereunder.

     Section 3.6    TERMINATION OF AGREEMENT. Subject to the provisions of
SECTION 3.10, the Borrowers shall have the right, at any time, to terminate this
Agreement upon not less than 60 days prior written notice to the Agent of their
intention to terminate this Agreement, which notice shall specify the effective
date of such termination. Upon receipt of such notice, the Agent shall promptly
notify each Lender thereof. On the date specified in such notice, such
termination shall be effected, PROVIDED, that the Borrowers shall, on or prior
to such date, pay to the Agent, for the account of the Lenders, in same day
funds, an amount equal to all Obligations then outstanding, including, without
limitation, all (a) accrued interest thereon, (b) all accrued fees provided for
hereunder, and (c) any amounts payable to the Agent and the Lenders pursuant to
SECTIONS 3.9, 3.10, 15.2 and 15.11, and, in addition thereto, shall deliver to
the Agent, in respect of each outstanding Letter of Credit, a supporting letter
of credit or cash collateral in an amount and on terms acceptable to the Agent.
Following a notice of termination as provided for in this SECTION 3.6 and upon
payment in full of the amounts specified in this SECTION 3.6, this Agreement
shall be terminated and the Agent, the Lenders and the Borrowers shall have no
further obligations to any other party hereto except for any indemnity
obligations which expressly survive the termination of this Agreement.

     Section 3.7    MAKING OF LOANS.

     (a)  NATURE OF OBLIGATIONS OF LENDERS TO MAKE LOANS. The obligations of the
Lenders under this Agreement to make the Loans are several and are not joint or
joint and several.

     (b)  ASSUMPTION BY AGENT. Subject to the provisions of SECTION 3.8 and
notwithstanding the occurrence or continuance of a Default or Event of Default
or other failure of any condition to the making of Revolving Credit Loans
hereunder subsequent to the Revolving Credit Loans to be made on the Effective
Date, unless the Agent shall have received notice from the Required Lenders in
accordance with the provisions of SECTION 3.7(c) prior to a proposed borrowing
date that such Lenders will not make available to the Agent such Lenders'
ratable portion of the amount to be borrowed on such date, the Agent may assume
that the Lenders will make such portion available to the Agent in accordance
with SECTION 2A.2, and the Agent may, in reliance upon such assumption, make
available to the Borrowers on such date a corresponding amount. If and to the
extent any Lender shall not make such ratable portion available to the Agent,
such Lender and the Borrowers severally agree to repay to the Agent forthwith on
demand such corresponding amount, together with interest thereon for each day
from the date such amount is made available to the Borrowers until the date such
amount is repaid to the Agent at the Effective Interest Rate or, if lower,
subject to SECTION 3.1(f), the Maximum Rate. If such Lender shall repay to the
Agent such corresponding amount, the amount so repaid shall constitute such
Lender's Commitment Percentage of the Loan made on such borrowing date for
purposes of this Agreement. The failure of any Lender to make its Commitment
Percentage of any Loan available shall not (without regard to whether the
Borrowers shall have returned the amount thereof to the Agent in accordance with
this SECTION 3.7) relieve it or any other Lender of its obligation, if any,
hereunder to make its Commitment Percentage of such Loan available on such
borrowing date, but no Lender shall be responsible for the failure of any other
Lender to make its Commitment Percentage of such Loan available on the borrowing
date.

     (c)  DELEGATION OF AUTHORITY TO AGENT. Without limiting the generality of
SECTION 13.1, each Lender expressly authorizes the Agent to determine on behalf
of such Lender (i) any reduction or increase of advance rates applicable to the
Borrowing Base, the German Equipment Acquisition Loan Limit and the U.S.
Equipment Acquisition Loan Limit so long as such advance rates do not at any
time exceed the rates set forth in the respective definitions of Borrowing Base,
German Equipment Acquisition Loan Limit and U.S. Equipment Acquisition Loan
Limit, (ii) the creation or elimination of any reserves (other than the Letter
of Credit Reserve) against the Revolving Credit Facility and the Borrowing Base,
(iii) whether or not Inventory or Receivables shall be deemed to constitute
Eligible Inventory or Eligible Receivables, and (iv) whether or not Equipment
shall be deemed to constitute Eligible Equipment. Such authorization may be
withdrawn by the Required Lenders by giving the Agent and the Borrowers' Agent
written notice of such withdrawal signed by the Required Lenders; PROVIDED,
HOWEVER, that unless otherwise agreed by the Agent (with prompt notice thereof
to the Borrowers' Agent) such withdrawal of authorization shall not become
effective until the thirtieth Business Day after receipt of such notice by the
Agent. Thereafter, the Required Lenders shall jointly instruct the Agent in
writing regarding such matters with such frequency as the Required Lenders shall
jointly determine. Unless and until the Agent shall have received written notice
from the Required Lenders as to the existence of a Default, an Event of Default
or some other circumstance which would relieve the Lenders of their respective
obligations to make Loans hereunder, which notice shall be in writing and shall
be signed by the Required Lenders and shall expressly state that the Required
Lenders do not intend to make available to the Agent such Lenders' ratable share
of Loans made after the effective date of such notice, the Agent shall be
entitled to continue to make the assumptions described in SECTION 3.7(b). The
notice described in the preceding sentence shall become effective on the third
Business Day after receipt of such notice by the Agent unless otherwise agreed
by the Agent. The Agent shall not be required to make any Loan as to which it
shall have received notice by a Lender of such Lender's intention not to make
its ratable portion of such Loan available to the Agent. Any withdrawal of
authorization under this SECTION 3.7(c) shall not affect the validity of any
Loans made prior to the effectiveness thereof.

     (d)  OVERADVANCES. Notwithstanding anything to the contrary contained
elsewhere in this SECTION 3.7 or this Agreement or the other Loan Documents, and
whether or not a Default or Event of Default exists at the time, unless the
Agent has received a written notice from the Required Lenders that such Lenders
do not intend to make available to the Agent such Lenders' ratable share of
Loans (which notice shall have become effective in accordance with the
provisions of SECTION 3.7), the Agent may in its discretion require all Lenders
to honor requests or deemed requests by the Borrowers for Revolving Credit Loans
at a time that an Overadvance exists or which would result in an Overadvance and
each Lender shall be obligated to continue to make its Proportionate Share of
Revolving Credit Loans, up to a maximum amount outstanding equal to its
Commitment to make Revolving Credit Loans, so long as such Overadvance is not
known by the Agent to exceed $500,000 and so long as such Overadvance is not
outstanding for more than 30 consecutive Business Days. "Overadvance" shall
mean, as of any date of determination, the amount, if any, by which (i) the
outstanding principal balance of Revolving Credit Loans exceeds (ii) the
Borrowing Base minus the minimum Availability required at such time pursuant to
SECTION 10.14.

     (e)  REPLACEMENT OF CERTAIN LENDERS. If a Lender (the "Affected Lender")
shall have failed to fund its Proportionate Share of any Loan requested (or
deemed requested) by the Borrowers which such Lender is obligated to fund under
the terms of this Agreement and which failure has not been cured, then, in any
such case and in addition to any other rights and remedies that the Agent, any
other Lender or the


                                      -36-
<PAGE>   43


Borrowers may have against such Affected Lender, the Agent or the Borrowers'
Agent may make written demand on such Affected Lender (with a copy to the
Borrowers' Agent, in the case of any demand by the Agent, and to the Agent, in
the case of any demand by the Borrowers' Agent) for the Affected Lender to
assign, and such Affected Lender shall assign pursuant to one or more duly
executed Assignment and Acceptances within 5 Business Days after the date of
such demand, to one or more Lenders willing to accept such assignment or
assignments, or to one or more Eligible Assignees designated by the Agent or the
Borrowers' Agent, as the case may be, all of such Affected Lender's rights and
obligations under this Agreement (including its Commitments and all Loans owing
to it) in accordance with ARTICLE 12. The Agent is hereby irrevocably authorized
to execute one or more Assignment and Acceptances as attorney-in-fact for any
Affected Lender which fails or refuses to execute and deliver the same within 5
Business Days after the date of such demand. The Affected Lender shall be
entitled to receive, in cash and concurrently with the execution and delivery of
each such Assignment and Acceptance, all amounts owed to the Affected Lender
hereunder or under any other Loan Document, including the aggregate outstanding
principal amount of the Loans owed to such Lender, together with accrued and
unpaid interest thereon through the date of such assignment. Upon the
replacement of any Affected Lender pursuant to this SECTION 3.7(e), such
Affected Lender shall cease to have any participation in, entitlement to, or
other right to share in the Security Interest or any other Lien of the Agent in
any Collateral and such Affected Lender shall have no further liability to the
Agent, any Lender or any other Person under any of the Loan Documents (except as
provided by applicable law, in SECTION 13.7 or elsewhere in this Agreement as to
events or transactions which occur prior to the replacement of such Affected
Lender).

     Section 3.8    SETTLEMENT AMONG LENDERS.

     (a)  EQUIPMENT ACQUISITION LOANS. The Agent shall pay to each Lender on
each Interest Payment Date or date on which a payment of principal is received
by the Agent with respect to the Equipment Acquisition Loans, as the case may
be, its ratable share, based on the principal amount of the Equipment
Acquisition Loans owing to such Lender, of all payments received by the Agent
hereunder in immediately available funds in respect of the principal of, or
interest on, the Equipment Acquisition Loans, net of any amounts payable by such
Lender to the Agent, by wire transfer of same day funds.

     (b)  REVOLVING CREDIT LOANS. It is agreed that each Lender's Net
Outstandings are intended by the Lenders to be equal at all times to such
Lender's Commitment Percentage of the aggregate principal amount of all
Revolving Credit Loans outstanding. Notwithstanding such agreement, the several
and not joint obligation of each Lender to fund Revolving Credit Loans made in
accordance with the terms of this Agreement ratably in accordance with such
Lender's Commitment Percentage and each Lender's right to receive its ratable
share of principal payments on Revolving Credit Loans in accordance with its
Commitment Percentage, the Lenders agree that in order to facilitate the
administration of this Agreement and the Loan Documents that settlement among
them may take place on a periodic basis in accordance with the provisions of
this SECTION 3.8.

     (c)  SETTLEMENT PROCEDURES AS TO REVOLVING CREDIT LOANS. To the extent and
in the manner hereinafter provided in this SECTION 3.8, settlement among the
Lenders as to Revolving Credit Loans may occur periodically on Settlement Dates
determined from time to time by the Agent, which may occur before or after the
occurrence or during the continuance of a Default or Event of Default and
whether or not all of the conditions set forth in SECTION 4.2 have been met. On
each Settlement Date payments shall be made by or to the Agent and the other
Lenders in the manner provided in this


                                      -37-
<PAGE>   44


SECTION 3.8 in accordance with the Settlement Report delivered by the Agent
pursuant to the provisions of this SECTION 3.8 in respect of such Settlement
Date so that as of each Settlement Date, and after giving effect to the
transactions to take place on such Settlement Date, each Lender's Net
Outstandings shall equal such Lender's Commitment Percentage of the Revolving
Credit Loans outstanding.

          (i)  SELECTION OF SETTLEMENT DATES. If the Agent elects, in its
     discretion, to settle accounts among the Lenders with respect to principal
     amounts of Revolving Credit Loans less frequently than each Business Day,
     then the Agent shall designate periodic Settlement Dates which may occur on
     any Business Day after the Effective Date; PROVIDED, HOWEVER, that the
     Agent shall designate as a Settlement Date any Business Day which is an
     Interest Payment Date; and PROVIDED FURTHER, that a Settlement Date shall
     occur at least once during each seven-day period. The Agent shall designate
     a Settlement Date by delivering to each Lender a Settlement Report not
     later than 12:00 noon on the proposed Settlement Date, which Settlement
     Report will be in the form of EXHIBIT E hereto and shall be with respect to
     the period beginning on the next preceding Settlement Date and ending on
     such designated Settlement Date.

          (ii) NON-RATABLE LOANS AND PAYMENTS. Between Settlement Dates, the
     Agent may (but shall not be obligated to) advance to the U.S. Borrowers out
     of its own funds, the entire principal amount of any Revolving Credit Loan
     requested or deemed requested pursuant to SECTION 2A.2 (any such Revolving
     Credit Loan being referred to as a "Non-Ratable Loan"). The making of each
     Non-Ratable Loan by the Agent shall be deemed to be a purchase by the Agent
     of a 100% participation in each other Lender's Commitment Percentage of the
     amount of such Non-Ratable Loan. All payments of principal, interest and
     any other amount with respect to such Non-Ratable Loan shall be payable to
     and received by the Agent for its own account. Upon demand by the Agent,
     each other Lender shall pay to the Agent, as the repurchase of such
     participation, an amount equal to 100% of such Lender's Commitment
     Percentage of the principal amount of such Non-Ratable Loan. Any payments
     received by the Agent between Settlement Dates which in accordance with the
     terms of this Agreement are to be applied to the reduction of the
     outstanding principal balance of Revolving Credit Loans, shall be paid over
     to and retained by the Agent for such application, and such payment to and
     retention by the Agent shall be deemed, to the extent of each other
     Lender's Commitment Percentage of such payment, to be a purchase by each
     such other Lender of a participation in the Revolving Credit Loans
     (including the repurchase of participations in Non-Ratable Loans) held by
     the Agent. Upon demand by another Lender, with notice thereof to the Agent,
     the Agent shall pay to such other Lender, as a repurchase of such
     participation, an amount equal to such other Lender's Commitment Percentage
     of any such amounts (after application thereof to the repurchase of any
     participations of the Agent in such other Lender's Commitment Percentage of
     any Non-Ratable Loans) paid only to the Agent.

          (iii) NET DECREASE IN OUTSTANDINGS. If on any Settlement Date the
     increase, if any, in the Dollar amount of any Lender's Net Outstandings
     which is required to comply with the first sentence of SECTION 3.8(b) is
     less than such Lender's Commitment Percentage of amounts received by the
     Agent for its own account since the next preceding Settlement Date, such
     Lender and the Agent, in their respective records, shall apply such
     Lender's Commitment Percentage of such amounts to the increase in such
     Lender's Net Outstandings, and the Agent shall pay to such Lender the
     excess allocable to such Lender.


                                      -38-
<PAGE>   45


          (iv) NET INCREASE IN OUTSTANDINGS. If on any Settlement Date the
     increase, if any, in the Dollar amount of any Lender's Net Outstandings
     which is required to comply with the first sentence of SECTION 3.8(b)
     exceeds such Lender's Commitment Percentage of amounts received by the
     Agent for its own account since the next preceding Settlement Date, such
     Lender and the Agent, in their respective records, shall apply such
     Lender's Commitment Percentage of such amounts to the increase in such
     Lender's Net Outstandings, and such Lender shall pay to the Agent, for the
     account of the Agent, any excess.

          (v)  NO CHANGE IN OUTSTANDINGS. If a Settlement Report indicates that
     no Revolving Credit Loans have been made during the period since the next
     preceding Settlement Date, then such Lender's Commitment Percentage of any
     amounts paid only to the Agent shall be paid by the Agent to such Lender.
     If a Settlement Report indicates that the increase in the Dollar amount of
     a Lender's Net Outstandings which is required to comply with the first
     sentence of SECTION 3.8(b) is exactly equal to such Lender's Commitment
     Percentage of amounts paid only to the Agent since the next preceding
     Settlement Date, such Lender and the Agent, in their respective records,
     shall apply such Lender's Commitment Percentage of such amounts to the
     increase in such Lender's Net Outstandings.

          (vi) RETURN OF PAYMENTS. If any amounts received by the Agent in
     respect of the Obligations (whether or not relating to the Revolving Credit
     Loans) are later required to be returned or repaid by the Agent to the
     Borrowers or any other Obligor or their respective representatives or
     successors in interest, whether by court order, settlement or otherwise, in
     excess of the Agent's Commitment Percentage of all such amounts required to
     be returned by all Lenders, each other Lender shall, upon demand by the
     Agent, pay to the Agent, for its own account, an amount equal to the excess
     of such Lender's Commitment Percentage of all such amounts required to be
     returned by all Lenders over the amount, if any, returned directly by such
     Lender.

          (vii) PAYMENTS TO AGENT, LENDERS.

               (A)  Payment by any Lender to the Agent shall be made not later
          than 1:00 p.m. on the Business Day such payment is due, PROVIDED that
          if such payment is due on demand by another Lender, such demand is
          made on the paying Lender not later than 10:00 a.m. on such Business
          Day. Payment by the Agent to any Lender shall be made by wire
          transfer, promptly following the Agent's receipt of funds for the
          account of such Lender and in the type of funds received by the Agent,
          PROVIDED that if the Agent receives such funds at or prior to 1:00
          p.m., the Agent shall pay such funds to such Lender by 2:00 p.m. on
          such Business Day. If a demand for payment is made after the
          applicable time set forth above, the payment due shall be made by 2:00
          p.m. on the first Business Day following the date of such demand.

               (B)  If a Lender shall, at any time, fail to make any payment to
          the Agent required hereunder, the Agent may, but shall not be required
          to, retain payments that would otherwise be made to such Lender
          hereunder and apply such payments to such Lender's defaulted
          obligations hereunder, at such time, and in such order, as the Agent
          may elect in its sole discretion.

               (C)  With respect to the payment of any funds under this SECTION
          3.8(c), whether from the Agent to a Lender or from a Lender to the
          Agent, the party failing to make full


                                      -39-
<PAGE>   46


          payment when due pursuant to the terms hereof shall, upon demand by
          the other party, pay such amount together with interest on such amount
          at the Federal Funds Effective Rate.

     (d)  SETTLEMENT OF OTHER OBLIGATIONS. All other amounts received by the
Agent on account of, or applied by the Agent to the payment of, any Obligation
owed to the Lenders (including, without limitation, fees payable to the Lenders
pursuant to SECTION 3.2 and proceeds from the sale of, or other realization
upon, all or any part of the Collateral following an Event of Default) that are
received by the Agent on or prior to 1:00 p.m. on a Business Day will be paid by
the Agent to each Lender on the same Business Day, and any such amounts that are
received by the Agent after 1:00 p.m. will be paid by the Agent to each Lender
on the following Business Day. Unless otherwise stated herein, the Agent shall
distribute fees payable to the Lenders pursuant to SECTION 3.2 ratably to the
Lenders based on each Lender's Commitment Percentage and shall distribute
proceeds from the sale of, or other realization upon, all or any part of the
Collateral following an Event of Default ratably to the Lenders based on the
amount of the Obligations then owing to each Lender.

     (e)  ALLOCATION OF PAYMENTS FROM BORROWERS. All monies to be applied to the
Obligations, whether such monies represent voluntary payments by the Borrowers
or are received pursuant to demand for payment or realized from any disposition
of Collateral, shall be allocated among the Agent and such of the Lenders and
other holders of the Obligations as are entitled thereto (and, with respect to
monies allocated to the Lenders, on a Ratable basis unless otherwise provided in
this SECTION 3.8(e)): (i) first, to the Agent to pay principal and accrued
interest on any portion of any Non-Ratable Loan which the Agent may have
advanced on behalf of any Lender (other than itself) and for which the Agent has
not been reimbursed by such Lender or the Borrowers; (ii) second, to the Agent
to pay the amount of expenses that have not been reimbursed to the Agent by the
Borrowers or the Lenders, together with interest accrued thereon; (iii) third,
to the Agent to pay any indemnified amount that has not been paid to the Agent
by the Borrowers or the Lenders, together with interest accrued thereon; (iv)
fourth, to the Agent to pay any fees due and payable to the Agent under this
Agreement; (v) fifth, to the Lenders for any indemnified amount that they have
paid to the Agent and for any expenses that they have reimbursed to the Agent;
(vi) sixth, to the Lenders in payment of the unpaid principal and accrued
interest in respect of the Loans and any other Obligations arising under this
Agreement (and the other Loan Documents) then outstanding and held by any Lender
to be shared among Lenders on a ratable basis, or on such other basis as may be
agreed upon in writing by all of the Lenders (which agreement or agreements may
be entered into without notice to or the consent or approval of the Borrowers);
and (vii) seventh, to the holders of the other Obligations who are not Lenders
on a pro rata basis. The allocations set forth in this SECTION 3.8(e) are solely
to determine the rights and priorities of the Agent and the Lenders as among
themselves and may be changed by the Agent and the Lenders without notice or the
consent of approval of the Borrowers or any other Person. Whenever allocation is
made pursuant to this SECTION 3.8(e) to the holder of Obligations in which
another Lender acquires a participation, the monies received by such holder
shall be shared as between such holder and such participants on a Ratable basis.

     Section 3.9    EURO PROVISIONS.

     (a)  If, as a result of the implementation of the European Economic and
Monetary Union ("EMU"), DM cease to be the lawful currency of Germany and are
replaced by the Euro, then any amount payable hereunder by any party hereto in
DM (including, without limitation, any German


                                      -40-
<PAGE>   47
Equipment Acquisition Loan to be made under this Agreement) shall instead be
payable in the Euro and the amount so payable shall be determined by
redenominating or converting such amount into the Euro at the exchange rate
officially fixed by the European Central Bank for the purpose of implementing
the EMU. Prior to the occurrence of the event described in the preceding
sentence, each amount payable hereunder in DM will, except as otherwise provided
herein, continue to be payable only in DM.

     (b)  The German Borrower shall from time to time, at the request of the
Agent, pay to the Agent for the account of each Lender the amount of any cost or
increased cost incurred by, or of any reduction in any amount payable to or in
the effective return on its capital to, or of interest or other return foregone
by, such Lender or any holding company of such Lender as a result of the
introduction of, changeover to or operation of the Euro in any applicable state.

     (c)  In addition, this Agreement (including, without limitation, the
definitions of Interbank Offered Rate and LIBOR) will be amended to the extent
determined by the Agent (acting reasonably and in consultation with the
Borrowers) to be necessary to reflect such implementation of the EMU and change
in currency and to put the Lenders and the Borrowers in the same position, so
far as possible, that they would have been in if such implementation and change
in currency had not occurred. Except as provided in the foregoing provisions of
this SECTION 3.9, no such implementation or change in currency nor any economic
consequences resulting therefrom shall (i) give rise to any right to terminate
prematurely, contest, cancel, rescind, alter, modify or renegotiate the
provisions of this Agreement or (ii) discharge, excuse or otherwise affect the
performance of any obligations of any Borrower under this Agreement, any Notes
or other Loan Documents.

     Section 3.10   PAYMENTS NOT AT END OF INTEREST PERIOD; FAILURE TO BORROW.
If for any reason any payment of principal with respect to any LIBOR Loan is
made on any day prior to the last day of the Interest Period applicable to such
LIBOR Loan or, after having given a Notice of Borrowing with respect to any
LIBOR Revolving Credit Loan or a Notice of Conversion or Continuation with
respect to any Loan to be continued as or converted into a LIBOR Loan, such Loan
is not made or is not continued as or converted into a LIBOR Loan due to the
Borrowers' failure to borrow or to fulfill the applicable conditions set forth
in ARTICLE 4, the Borrowers shall pay to each Lender upon the request of the
Agent or such Lender, in addition to any amounts that may be due under SECTION
3.9, an amount sufficient to compensate each Lender for any and all losses or
expenses which such Lender has sustained or incurred as a consequence thereof.
The Borrowers shall pay such amount upon presentation by the Agent (or as to any
Lender, by such Lender) of a statement setting forth the amount and the Agent's
(or such Lender's) calculation thereof pursuant hereto, which statement shall be
deemed true and correct absent manifest error.

     Section 3.11   ASSUMPTIONS CONCERNING FUNDING OF LIBOR LOANS. Calculation
of all amounts payable to the Lenders under this ARTICLE 3 shall be made as
though each Lender had actually funded or committed to fund its LIBOR Loans
through the purchase of an underlying deposit in an amount equal to the amount
of such Ratable share and having a maturity comparable to the relevant Interest
Period for such LIBOR Loan; PROVIDED, HOWEVER, each Lender may fund its LIBOR
Loans in any manner it deems fit and the foregoing assumption shall be utilized
only for the calculation of amounts payable under this ARTICLE 3.

     Section 3.12 NOTICE OF CONVERSION OR CONTINUATION. Whenever the Borrowers
desire, subject to the provisions of SECTION 3.13, to convert an outstanding
Loan into a Loan or Loans of a different Type or to continue all or a portion of
an outstanding LIBOR Loan for a subsequent Interest Period, the Borrowers' Agent
shall notify the Agent by telephone or in writing by telex or facsimile
transmission (which notice shall be irrevocable) not later than 11:00 a.m. on
the date three Business Days before the day on which such proposed conversion or
continuation is to be effective (and such effective date of any continuation
shall be the last day of the Interest Period for the applicable LIBOR Loan),
provided the Borrowers shall not be permitted to convert Loans into (or continue
Loans as) LIBOR Loans at any time during the existence of an Event of Default.
Each such notice (a "Notice of Conversion or Continuation") shall (a) identify
the Loan to be converted or continued, the aggregate outstanding principal
balance thereof and, if a LIBOR Loan, the last day of the Interest Period
applicable to such Loan, (b) specify the effective date of such conversion or
continuation, (c) specify the principal amount of such Loan to be converted or
continued and, if converted, the Type or Types into which the same is to be
converted (it being understood that all German Equipment Acquisition Loans shall
be LIBOR Loans), and (d) the Interest Period to be applicable to LIBOR Loan as
converted or continued, and shall, if notice thereof was originally given by
telephone, be immediately followed by a signed, written confirmation thereof by
the Borrowers' Agent in a form acceptable to the Agent, PROVIDED that the
failure to provide a written confirmation shall not invalidate any telephonic
notice and, if such written confirmation differs in any respect from the action
taken by the Lenders, the records of the Agent shall control absent manifest
error.

     Section 3.13   CONVERSION OR CONTINUATION. Subject to the provisions of
SECTIONS 3.12 and 3.15, the Borrowers may request that all or any part of any
outstanding Loan be converted into a Loan or Loans of a different Type or be
continued as a Loan or Loans of the same Type, in the same aggregate principal
amount, on any Business Day (which, in the case of continuation of a LIBOR Loan,
shall be the last day of the Interest Period applicable to such Loan), upon
notice (which notice shall be irrevocable) given in accordance with SECTION
3.12, PROVIDED that (a) if an Event of Default exists, the U.S. Borrowers shall
not be permitted to continue Loans as, or convert Loans into, LIBOR Loans, (b)
nothing in this ARTICLE 3 shall be construed to permit the conversion of a
German Equipment Acquisition Loan to a Prime Rate Loan, and (c) nothing in this
ARTICLE 3 shall be construed to permit the conversion of a Revolving Credit Loan
to an Equipment Acquisition Loan, or vice versa, or the conversion of a U.S.
Equipment Acquisition Loan to a German Equipment Acquisition Loan, or vice
versa.

     Section 3.14   DURATION OF INTEREST PERIODS; MAXIMUM NUMBER OF LIBOR LOANS;
MINIMUM INCREMENTS

     (a)  Subject to the provisions of the definition of "Interest Period", the
duration of each Interest Period applicable to a LIBOR Loan shall be as
specified in the applicable Notice of Borrowing or Notice of Conversion or
Continuation. The Borrowers may elect a subsequent Interest Period to be
applicable to any LIBOR Loan by giving a Notice of Conversion or Continuation
with respect to such Loan in accordance with SECTION 3.12.

     (b)  If the Agent does not receive a notice of election in accordance with
SECTION 3.12 with respect to the continuation of a Dollar LIBOR Loan within the
applicable time limits specified in said SECTION 3.12, or if, when such notice
must be given, an Event of Default exists or such Type of Loan is not available,
the Borrowers shall be deemed to have elected to convert such Dollar LIBOR Loan
in whole into a Prime Rate Loan on the last day of the Interest Period therefor.
If the Agent does not receive a notice of election in accordance with SECTION
3.12 with respect to the continuation of an Alternate


                                      -42-
<PAGE>   49


Currency LIBOR Loan within the applicable time limits specified in said SECTION
3.12, the German Borrower shall be deemed to have elected to continue such
Alternate Currency LIBOR Loan in whole on the last day of the Interest Period
therefor as an Alternate Currency LIBOR Loan with a one month Interest Period.

     (c)  Notwithstanding the foregoing, the Borrowers may not select an
Interest Period that would end, but for the provisions of the definition
"Interest Period," after the Termination Date.

     (d)  In no event shall there be more than five Dollar LIBOR Loans or two
Alternate Currency LIBOR Loans outstanding hereunder at any time. For the
purpose of this SUBSECTION (D), each LIBOR Revolving Credit Loan and each LIBOR
Equipment Acquisition Loan having a distinct Interest Period shall be deemed to
be a separate Loan hereunder.

     (e)  Each LIBOR Loan shall be in a minimum amount of $500,000 or the
Alternate Currency Equivalent thereof.

     Section 3.15   CHANGED CIRCUMSTANCES.

     (a)  If the introduction of or any change in or in the interpretation of
(in each case, after the date hereof) any law or regulation makes it unlawful,
or any Governmental Authority asserts, after the date hereof, that it is
unlawful, for any Lender to perform its obligations hereunder to make LIBOR
Loans or to fund or maintain LIBOR Loans hereunder, such Lender shall notify the
Agent of such event and the Agent shall notify the Borrowers' Agent of such
event, and the right of the Borrowers to select LIBOR Loans for any subsequent
Interest Period or in connection with any subsequent conversion of any Loan
shall be suspended until the Agent shall notify the Borrowers' Agent that the
circumstances causing such suspension no longer exist, and the Borrowers shall
convert each Dollar LIBOR Loan into a Prime Rate Loan, and the Borrowers and the
Agent shall in good faith agree upon an alternate interest rate (including
margin) to apply to all existing and future German Equipment Acquisition Loans
(the "Alternate Interest Rate"), such Alternate Interest Rate (including margin)
to be established so as to compensate the Lenders for the making of German
Equipment Acquisition Loans on substantially identical terms as with respect to
Alternate Currency LIBOR Loans, with the interest rate on all German Equipment
Acquisition Loans automatically being converted to such Alternate Interest Rate,
and the Borrowers shall pay all interest accrued thereon through the date of
such prepayment or conversion; PROVIDED, that if the date of such proposed
conversion is not the last day of the Interest Period applicable to such LIBOR
Loan, the Borrowers shall also pay any amount due pursuant to SECTION 3.10,
unless such conversion arises out of an assertion by a Governmental Authority
that it is unlawful for any Lender to perform its obligations hereunder to make
LIBOR Loans or to fund or maintain LIBOR Loans hereunder, which assertion is
based solely on the actions of such Lender and does not apply generally to other
similarly situated financial institutions.

     (b)  If the Agent shall, at least one Business Day before the date of any
requested Loan or the effective date of any conversion or continuation of an
existing Loan to be made or continued as or converted into a LIBOR Loan (each
such requested Loan made and Loan to be converted or continued, a "PENDING
LOAN"), notify the Borrowers' Agent that LIBOR will not adequately reflect the
cost to the Lenders of making or funding such Pending Loan as a LIBOR Loan or
that the Interbank Offered Rate is not reasonably determinable, including from
any interest rate reporting service of recognized standing, then the right of
the Borrowers to select LIBOR Loans for such Pending Loan, any subsequent Loan
or in


                                      -43-
<PAGE>   50


connection with any subsequent conversion or continuation of any Loan shall be
suspended until the Agent shall notify the Borrowers' Agent that the
circumstances causing such suspension no longer exist, and each Pending Loan and
each such subsequent Loan requested to be made, continued or converted shall be
made or continued as or converted into a Prime Rate Loan, in the case of
Revolving Credit Loans and U.S. Equipment Acquisition Loans, and into Loans
based on the Alternate Interest Rate (as defined in SECTION 3.15(a)), in the
case of German Equipment Acquisition Loans.

     (c)  If, due to either (i) the introduction of or any change (other than
any change by way of imposition or increase of reserve requirements included in
the LIBOR Reserve Percentage) in or in the interpretation of, in each case after
the date hereof, any law or regulation (except to the extent such introduction,
change or interpretation affects taxes measured by net income), or (ii) the
compliance with a guideline or request (except to the extent such guideline or
request affects taxes measured by net income) from any central bank or other
governmental authority (whether nor not having the force of law) made after the
date hereof, there shall be any increase in the cost to any Lender of agreeing
to make or making, funding or maintaining LIBOR Loans (other than as separately
provided for in SECTION 3.15(d)), then the Borrowers shall from time to time,
within 30 days after demand by such Lender (with a copy of such demand to the
Agent), pay to the Agent for the account of such Lender additional amounts
sufficient to compensate such Lender for such increased cost.

     (d)  If (i) the adoption of or change in, after the date hereof, any law,
rule, regulation or guideline regarding capital requirements for banks or bank
holding companies, or any change, after the date hereof, in the interpretation
or application thereof by any governmental authority charged with the
interpretation or administration thereof, or (ii) compliance by such Lender with
any guideline, request or directive, made or promulgated after the date hereof,
of any such entity regarding capital adequacy (whether or not having the force
of law), has the effect of reducing the return on a Lender's capital as a
consequence of its maintaining its Loans or commitment to make Loans hereunder
to a level below that which such Lender could have achieved but for such
adoption, change or compliance (taking into consideration such Lender's policies
with respect to capital adequacy immediately before such adoption, change or
compliance and assuming the full utilization of such Lender's capital
immediately before such adoption, change or compliance) or if any change in law,
regulation, treaty or official directive or the interpretation or application
thereof by any court or by any governmental authority charged with the
administration thereof or the compliance with any guideline or request of any
central bank or other governmental authority (whether or not having the force of
law) subjects a Lender to any tax with respect to payments of principal or
interest or any other amounts payable hereunder by the Borrowers or otherwise
with respect to the transactions contemplated hereby (except for taxes on the
overall net income of such Lender imposed by the United States of America or any
political subdivision thereof), in each case by any amount deemed by such Lender
to be material, then such Lender shall promptly after its determination of such
occurrence notify the Borrowers' Agent and the Agent thereof. The Borrowers
agree to pay to the Agent, for the account of such Lender, as an additional fee
from time to time, within 30 days after demand by such Lender, such amount as
such Lender certifies to be the amount that will compensate it for such
reduction.

     (e)  Before giving any notice pursuant to SECTION 3.15(a) or making any
demand pursuant to SECTION 3.15(c) or (d), each Lender agrees to use its
reasonable efforts (consistent with its internal policy and legal and regulatory
restrictions) to designate a different lending office if the making of such a
designation would avoid the need for such notice or demand, or reduce the amount
of such increased cost


                                      -44-
<PAGE>   51


or reduction in return and would not, in the judgment of such Lender, be
otherwise disadvantageous to such Lender.

     (f)  A certificate of a Lender claiming compensation under SECTION 3.15(c)
or (d) shall be conclusive in the absence of manifest error. Such certificate
shall set forth the nature of the occurrence giving rise to such compensation,
the additional amount or amounts to be paid to it hereunder, and the method by
which such amounts were determined. In determining such amount, a Lender may use
any reasonable averaging and attribution methods.

     Section 3.16.  BORROWERS' AGENT. Each of the Borrowers other than Parent
hereby appoints Parent as, and Parent shall act under this Agreement as, the
agent, attorney-in-fact and legal representative of such other Borrowers for all
purposes, including requesting Loans and receiving account statements and other
notices and communications to the Borrowers (or any of them) from the Agent or
any Lender. The Agent and the Lenders may rely, and shall be fully protected in
relying, on any Notice of Borrowing, Notice of Conversion or Continuation,
request for a Letter of Credit, disbursement instruction, report, information or
any other notice or communication made or given by Parent, whether in its own
name, as Borrowers' Agent, on behalf of any other Borrower or on behalf of "the
Borrowers", and neither the Agent nor any Lender shall have any obligation to
make any inquiry or request any confirmation from or on behalf of any other
Borrower as to the binding effect on it of any such Notice, request,
instruction, report, information, other notice or communications, nor shall the
joint and several character of the U.S. Borrowers' obligations hereunder be
affected, PROVIDED that the provisions of this SECTION 3.16 shall not be
construed so as to preclude any Borrower from taking actions permitted to be
taken by "a Borrower" hereunder.

     Section 3.17.  JOINT AND SEVERAL LIABILITY.

     (a)  JOINT AND SEVERAL LIABILITY. All Loans made to the U.S. Borrowers and
all of the other Obligations of the U.S. Borrowers, including all interest, fees
and expenses with respect thereto (collectively, the "U.S. OBLIGATIONS"), shall
constitute one joint and several direct and general obligation of all of the
U.S. Borrowers. Notwithstanding anything to the contrary contained herein, each
of the U.S. Borrowers shall be jointly and severally, with each other U.S.
Borrower, directly and unconditionally liable to the Agent and the Lenders for
all U.S. Obligations, it being agreed that the advances to each U.S. Borrower
inure to the benefit of all U.S. Borrowers, and that the Agent and the Lenders
are relying on the joint and several liability of the U.S. Borrowers as
co-makers in extending the Loans hereunder and arranging for the issuance of
Letters of Credit. Each U.S. Borrower hereby unconditionally and irrevocably
agrees that upon default in the payment when due (whether at stated maturity, by
acceleration or otherwise) of any principal of, or interest on, any U.S.
Obligation payable to the Agent or any Lender, it will forthwith pay the same,
without notice or demand, unless such payment is then prohibited by applicable
law (provided such U.S. Obligation shall not be extinguished by any such
prohibition).

     (b)  NO REDUCTION IN OBLIGATIONS. No payment or payments made by any of the
U.S. Borrowers or any other Person or received or collected by the Agent or any
Lender from any of the U.S. Borrowers or any other Person by virtue of any
action or proceeding or any setoff or appropriation or application at any time
or from time to time in reduction of or in payment of the U.S. Obligations shall
be deemed to modify, reduce, release or otherwise affect the liability of each
U.S. Borrower under this Agreement, which shall remain liable for the U.S.
Obligations until the U.S. Obligations are paid in full and the Revolving Credit
Facility and the Equipment Acquisition Loan Facility are terminated.


                                      -45-
<PAGE>   52


     Section 3.18.  U.S. OBLIGATIONS ABSOLUTE. Each U.S. Borrower agrees that
the U.S. Obligations will be paid strictly in accordance with the terms of the
Loan Documents, regardless of any law, regulation or order now or hereafter in
effect in any jurisdiction affecting any of such terms or the rights of the
Agent or any Lender with respect thereto, unless such payment is then prohibited
by applicable law (provided such U.S. Obligation shall not be extinguished by
any such prohibition). All U.S. Obligations shall be conclusively presumed to
have been created in reliance hereon. The liabilities under this Agreement shall
be absolute and unconditional irrespective of: (a) any lack of validity or
enforceability of any Loan Document or any other agreement or instrument
relating thereto; (b) any change in the time, manner or place of payments of, or
in any other term of, all or any part of the U.S. Obligations, or any other
amendment or waiver thereof or any consent to departure therefrom, including any
increase in the U.S. Obligations resulting from the extension of additional
credit to any U.S. Borrower or otherwise; (c) any taking, exchange, release or
non-perfection of any Collateral, or any release or amendment or waiver of or
consent to departure from any guaranty for all or any of the U.S. Obligations;
(d) any change, restructuring or termination of the corporate structure or
existence of any U.S. Borrower; or (e) any other circumstance which might
otherwise constitute a defense available to, or a discharge of, any U.S.
Borrower. This Agreement shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the U.S. Obligations is
rescinded or must otherwise be returned by the Agent or any Lender upon the
insolvency, bankruptcy or reorganization of any U.S. Borrower or otherwise, all
as though such payment had not been made.

     Section 3.19. WAIVER OF SURETYSHIP DEFENSES. Each U.S. Borrower agrees that
the joint and several liability of the U.S. Borrowers provided for in SECTION
3.17 shall not be impaired or affected by any modification, supplement,
extension or amendment of any contract or agreement to which the other U.S.
Borrowers may hereafter agree (other than an agreement signed by the Agent and
the Lenders specifically releasing such liability), nor by any delay, extension
of time, renewal, compromise or other indulgence granted by the Agent or any
Lender with respect to any of the U.S. Obligations, nor by any other agreements
or arrangements whatever with the other U.S. Borrowers or with anyone else, each
U.S. Borrower hereby waiving all notice of such delay, extension, release,
substitution, renewal, compromise or other indulgence, and hereby consenting to
be bound thereby as fully and effectually as if it had expressly agreed thereto
in advance. The liability of each U.S. Borrower is direct and unconditional as
to all of the U.S. Obligations, and may be enforced without requiring the Agent
or any Lender first to resort to any other right, remedy or security. Each U.S.
Borrower hereby expressly waives promptness, diligence, notice of acceptance and
any other notice (except to the extent expressly provided for herein or in
another Loan Document) with respect to any of the U.S. Obligations, the Notes,
this Agreement or any other Loan Document and any requirement that the Agent or
any Lender protect, secure, perfect or insure any Lien or any property subject
thereto or exhaust any right or take any action against any U.S. Borrower or any
other Person or any collateral, including any rights any U.S. Borrower may
otherwise have under O.C.G.A. ss. 10-7-24 or any successor statute or any
analogous statute in any jurisdiction under the laws of which any U.S. Borrower
is incorporated or in which any U.S. Borrower conducts business.

     Section 3.20   CONTRIBUTION AND INDEMNIFICATION AMONG THE U.S. BORROWERS.
Each U.S. Borrower is obligated to repay the U.S. Obligations as joint and
several obligors under this Agreement. To the extent that any U.S. Borrower
shall, under this Agreement as a joint and several obligor, repay any of the
U.S. Obligations constituting Loans made to another U.S. Borrower hereunder or
other U.S. Obligations incurred directly and primarily by any other U.S.
Borrower (an "Accommodation Payment"), then the U.S. Borrower making such
Accommodation Payment shall be entitled to


                                      -46-
<PAGE>   53


contribution and indemnification from, and be reimbursed by, each of the other
U.S. Borrowers in an amount, for each of such other U.S. Borrowers, equal to a
fraction of such Accommodation Payment, the numerator of which fraction is such
other U.S. Borrower's "Allocable Amount" (as defined below) and the denominator
of which is the sum of the Allocable Amounts of all of the U.S. Borrowers. As of
any date of determination, the "Allocable Amount" of each U.S. Borrower shall be
equal to the maximum amount of liability for Accommodation Payments which could
be asserted against such U.S. Borrower hereunder without (a) rendering such U.S.
Borrower "insolvent" within the meaning of Section 101(31) of Title 11 of the
United States Code entitled "Bankruptcy" (the "Bankruptcy Code"), Section 2 of
the Uniform Fraudulent Transfer Act (the "UFTA"), Section 2 of the Uniform
Fraudulent Conveyance Act ("UFCA"), or Section 18-2-22 of the Official Code of
Georgia Annotated, (b) leaving such U.S. Borrower with unreasonably small
capital or assets, within the meaning of Section 548 of the Bankruptcy Code,
Section 4 of the UFTA, or Section 4 of the UFCA, or (c) leaving such U.S.
Borrower unable to pay its debts as they become due within the meaning of
Section 548 of the Bankruptcy Code, Section 4 of the UFTA, or Section 5 of the
UFCA. All rights and claims of contribution, indemnification and reimbursement
under this SECTION 3.20 shall be subordinate in right of payment to the prior
payment in full of the U.S. Obligations.

     Section 3.21. TAXES. Except as otherwise required by applicable law, each
payment by the Borrowers under this Agreement and the other Loan Documents shall
be made without setoff or counterclaim and without withholding for or on account
of any present or future taxes imposed by or within the jurisdiction in which
any Borrower is domiciled, any jurisdiction from which the Borrowers make any
payment hereunder, or (in each case) any political subdivision or taxing
authority thereof or therein (excluding any such tax imposed on the overall net
income of the Agent or the Lenders). If any such withholding is so required, the
Borrowers shall make the withholding, pay the amount withheld to the appropriate
governmental authority before penalties attach thereto or interest accrues
thereon, and forthwith pay such additional amount as may be necessary to ensure
that the net amount actually received free and clear of such taxes (including
such taxes on such additional amount) is equal to the amount which Agent or the
Lenders would have received had such withholding not been made. If the Agent or
the Lenders pay any amount in respect of any such taxes, penalties or interest,
the Borrowers shall reimburse the Agent or the Lenders (as appropriate) for that
payment on demand in the currency in which such payment was made. If a Borrower
pays any such taxes, penalties or interest, it shall deliver official tax
receipts evidencing that payment or certified copies thereof to the Agent on or
before the thirtieth day after payment.

                        ARTICLE 4 - CONDITIONS PRECEDENT

     Section 4.1 CONDITIONS PRECEDENT TO INITIAL LOANS. Notwithstanding any

in substantial compliance with all other applicable laws relating to it,
including, without being limited to, all Environmental Laws and all occupational
health and safety laws applicable to such Borrower or its properties, except for

Adverse Effect and in respect of which adequate reserves have been established
on the books of such Borrower to the extent required by GAAP.

Adverse Effect, and (ii) no event has occurred or failed to occur which has had,
or could reasonably be expected to have, a Materially Adverse Effect.

properties may be bound or which would require any Borrower to make any payment
thereunder prior to the scheduled maturity date therefor.

to in the future have, a Materially Adverse Effect which has not been set forth
in the financial statements or disclosure delivered prior to the Effective Date,
in each case referred to in SECTION 5.1(m), or in such written information,
reports or other papers or data or otherwise disclosed in writing to the Agent
or any Lender prior to the Effective Date.

represented by the Loans outstanding and to be incurred and the transactions
contemplated by this Agreement, each Borrower is solvent, having assets of a
fair value which exceeds the amount required to pay its debts (including
contingent, subordinated, unmatured and unliquidated liabilities) as they become

years immediately preceding the Agreement Date.

Certificate delivered to the Agent meets the criteria enumerated in the

assessment of all areas within their and each of their Subsidiaries' business
and operations (including those affected by suppliers, vendors and customers)
that could be adversely affected by the "Year 2000 Problem" (that is, the risk
that computer applications used by the Borrowers or any of their Subsidiaries
(or suppliers, vendors and customers) may be unable to recognize and perform
properly date-sensitive functions involving certain dates prior to and any date
after December 31, 1999), (b) developed a plan and timeline for addressing the
Year 2000 Problem on a timely basis, and (c) to date, implemented that plan in
accordance with that timetable. Based on the foregoing, each Borrower believes
that all computer applications (including those of its suppliers, vendors and
customers) that are material to its or any of its Subsidiaries' business and
operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates on, before and after January 1,

are listed on SCHEDULE 5.1(x).

     (y)  FEDERAL REGULATIONS. No Borrower is engaged, principally or as one of
its important activities, in the business of extending credit for the purpose of
"purchasing" or "carrying" any "margin stock" (as each of the quoted terms is
defined or used in Regulation U of the Board of Governors of the Federal Reserve
System).

company "controlled" by an "investment company" (as each of the quoted terms is
defined or used in the Investment Company Act of 1940, as amended).

been recognized as the representative of any Borrower's employees; no Borrower
knows of any pending, threatened or contemplated strikes, work stoppage or other
labor disputes involving its employees or those of its Subsidiaries.

by or on behalf of any Borrower pursuant to or in connection with this Agreement
or any of the other Loan Documents (including, but not limited to, any such
representation, warranty or statement made in or in connection with any
amendment thereto) shall constitute representations and warranties made under
this Agreement. All representations and warranties made under this Agreement
shall be made or deemed to be made at and as of the Agreement Date, at and as of
the Effective Date and at and as of the date of each Loan, except that (a)
representations and warranties which, by their terms are applicable only to any

Schedules attached hereto unless the Borrowers have failed to update such
Schedules to the extent and within the timeframe set forth in SECTION 8.10. All
representations and warranties made or deemed to be made under this Agreement
shall survive and not be waived by the execution and delivery of this Agreement,

                          ARTICLE 6 - SECURITY INTEREST

     Section 6.1    SECURITY INTEREST. (a) To secure the payment, observance and
performance of the Secured Obligations, each U.S. Borrower hereby mortgages,
pledges and assigns all of the Collateral to the Agent, for the benefit of
itself as Agent and the Lenders and the Issuing Bank, and grants to the Agent,
for the benefit of itself as Agent and the Lenders and the Issuing Bank, a
continuing security interest in, and a continuing Lien upon, all of the
Collateral.

     (b)  As additional security for all of the Secured Obligations, each U.S.
Borrower grants to the Agent, for the benefit of itself as Agent and the Lenders
and the Issuing Bank, a security interest in, and assigns to the Agent, for the
benefit of itself as Agent and the Lenders and the Issuing Bank, all of such
U.S. Borrower's right, title and interest in and to any deposits or other sums
at any time credited by or due from each Lender and the Issuing Bank to such
U.S. Borrower, with the same rights therein as if the deposits or other sums
were credited by or due from such Lender. Each U.S. Borrower hereby authorizes
each Lender and the Issuing Bank to pay or deliver to the Agent, for the account
of the Lenders, without any necessity on the Agent's or any Lender's part to
resort to other security or sources of reimbursement for the Secured
Obligations, at any time during the continuation of any Event of Default,
without further notice to any U.S. Borrower (such notice being expressly
waived), any of the aforesaid deposits (general or special, time or demand,
provisional or final) or other sums for application to any Secured Obligation,
irrespective of whether any demand has been made or whether such Secured
Obligation is mature, and the rights given the Agent, the Lenders and the
Issuing Bank hereunder are cumulative with such Person's other rights and
remedies, including other rights of set-off. The Agent will promptly notify the
Borrowers' Agent of its receipt of any such funds for application to the Secured
Obligations, but failure to do so will not affect the validity or enforceability
thereof. The Agent may give notice of the above grant of a security interest in
and assignment of the aforesaid deposits and other sums, and authorization, to,
and make any suitable arrangements with, any Lender or the Issuing Bank for
effectuation thereof, and each U.S. Borrower hereby irrevocably appoints the
Agent as its attorney to collect any and all such deposits or other sums to the
extent any such payment is not made to the Agent or any Lender by such Lender or
the Issuing Bank.

shall not at any time be subject to any Liens that are prior to, on a parity
with or junior to the Security Interest, other than Permitted Liens.

     (b)  Each U.S. Borrower shall, at its sole cost and expense, take all
action that may be necessary or desirable, or that the Agent may reasonably
request, so as at all times to maintain the validity, perfection, enforceability
and rank of the Security Interest in the Collateral in conformity with the
requirements of SECTION 6.2(a) or to enable the Agent and the Lenders to
exercise or enforce their rights hereunder, including, but not limited to: (i)
paying all taxes, assessments and other claims lawfully levied or assessed on
any of the Collateral, except to the extent that such taxes, assessments and
other claims constitute Permitted Liens, (ii) upon the Agent's reasonable
request, diligently seeking to obtain, after the Agreement Date, landlords',
mortgagees' or mechanics' releases, subordinations or waivers, (iii) delivering
to the Agent, endorsed or accompanied by such instruments of assignment as the
Agent may specify, any and all chattel paper and instruments, evidencing or
forming a part of the Collateral, (iv) upon the Agent's reasonable request,

designations, hypothecations, notices and assignments, in each case in form and
substance satisfactory to the Agent, relating to the creation, validity,
perfection, maintenance or continuation of the Security Interest under the UCC
or other applicable law.

     (c)  The Agent is hereby authorized to file one or more financing or
continuation statements or amendments thereto without the signature of or in the
name of any U.S. Borrower for any purpose described in SECTION 6.2(b). A carbon,

     10 days' notice to the Borrower's Agent of the time and place of any public
     sale or the time after which any private sale is to be made shall

     (a)  RIGHTS CUMULATIVE. The rights and remedies of the Agent and the
Lenders under this Agreement, the Note and each of the Loan Documents shall be
cumulative and not exclusive of any rights or remedies which it or they would
otherwise have. In exercising such rights and remedies, the Agent or any Lender
may be selective and no failure or delay by the Agent or any Lender in
exercising any right shall operate as a waiver of such right nor shall any
single or partial exercise of any power or right preclude its other or further
exercise or the exercise of any other power or right.

     (b)  WAIVER OF MARSHALLING. Each Borrower hereby waives any right to
require any marshalling of assets and any similar right.

     (c)  LIMITATION OF LIABILITY. Nothing contained in this ARTICLE 11 or
elsewhere in this Agreement or in any of the Loan Documents shall be construed
as requiring or obligating the Agent or any Lender or any agent or designee of
the Agent or any Lender to make any demand or to make any inquiry as to the
nature or sufficiency of any payment received by it or to present or file any
claim or


                                      -80-
<PAGE>   87


notice or take any action with respect to any Receivable or any other Collateral
or the moneys due or to become due thereunder or in connection therewith or to
take any steps necessary to preserve any rights against prior parties, and
neither the Agent or any Lender nor any of their agents or designees shall have
any liability to any Borrower for actions taken pursuant to this ARTICLE 11, any
other provision of this Agreement or any of the Loan Documents, so long as the
Agent or such Lender or such agent or designee shall act reasonably and in good
faith.

     (d)  APPOINTMENT OF RECEIVER. In any action under this ARTICLE 11, the
Agent shall be entitled to the appointment of a receiver, without notice of any

the nonexclusive right and license to use any trademark then used by such
Borrower, for the purposes set forth in SECTION 11.2(c) and for the purpose of
enabling the Agent to realize on the Collateral and to permit any purchaser of
any portion of the Collateral through a foreclosure sale or any other exercise
of the Agent's rights and remedies under the Loan Documents to use, sell or
otherwise dispose of the Collateral bearing any such trademark. Such right and
license is granted in consideration of this Agreement, without the requirement
that any monetary payment whatsoever be made to such Borrower or any other
Person by the Agent or any Lender. Each Borrower hereby represents, warrants,
covenants and agrees that it presently has, and shall continue to have, the
right, without the approval or consent of others, to grant the license set forth
in this SECTION 11.6.

the Lenders and the Commitment Percentage of, and principal amount of the Loans

is not an Affiliate of such Lender shall give prompt notice thereof to the
Borrowers' Agent.

     (g)  Any Lender may, in connection with any assignment, proposed
assignment, participation or proposed participation pursuant to this SECTION

Acquisition Loan Limit", respectively), together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement or such other Loan Documents, the Agent shall not
have any duties or responsibilities, except those expressly set forth herein and
therein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or the other Loan Documents or otherwise exist
against the Agent.

     Section 13.2   DELEGATION OF DUTIES. The Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

     Section 13.3   EXCULPATORY PROVISIONS. Neither the Agent nor any of
its trustees, officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall (a) be liable to any Lender (or any Lender's participants) for
any action lawfully taken or omitted to be taken by it or such Person under or
in connection with this Agreement or the other Loan Documents (except for its or
such Person's own gross negligence or willful misconduct), (b) be responsible in
any manner to any Lender (or any Lender's participants) for any recitals,
statements, representations or warranties made by any Borrower or any of its
Subsidiaries or any officer thereof contained in this Agreement or the other
Loan Documents or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agent under or in connection
with, this Agreement or the other Loan Documents, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the other Loan Documents or for any failure of any Borrower or any of its
Subsidiaries to perform their obligations hereunder or thereunder, or (c) have
any obligation whatsoever to any of the Lenders to assure that the Collateral
exists or is owned by the Borrowers or is cared for, protected or insured or has
been encumbered, or that the Agent's Liens have


                                      -84-
<PAGE>   91


been properly or sufficiently or lawfully created, perfected, protected or
enforced or are entitled to any particular priority, or to exercise at all or in
any particular manner or under any duty of care, disclosure or fidelity, or to
continue exercising, any of the rights, authorities and powers granted or
available to the Agent pursuant to any of the Loan Documents, it being
understood and agreed that in respect of the Collateral, or any act, omission or
event related thereto, the Agent may act in any manner it may deem appropriate,
in its sole discretion, given the Agent's own interest in the Collateral in its
capacity as one of the Lenders and that the Agent shall have no other duty or
liability whatsoever to any Lender as to any of the foregoing. The Agent shall
not be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement, or to inspect the properties, books or records of any
Borrower or any of its Subsidiaries.

     Section 13.4   RELIANCE BY AGENT. The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including
counsel to any Borrower or any of its Subsidiaries), independent accountants and
other experts selected by the Agent. The Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with SECTION 12.1. The Agent shall be fully justified
in failing or refusing to take any action under this Agreement and the other
Loan Documents unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement and the Notes in accordance with a request of the
Required Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Notes.

     Section 13.5   NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Lender or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the Agent
receives such a notice, the Agent shall promptly give notice thereof to the
Lenders. The Agent shall take such action with respect to such Default or Event
of Default as shall be reasonably directed by the Required Lenders; PROVIDED
that unless and until the Agent shall have received such directions, the Agent
may (but shall not be obligated to) continue making Revolving Credit Loans to
the Borrowers on behalf of the Lenders in reliance on the provisions of SECTION
3.7 and take such other action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

     Section 13.6   NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender
expressly acknowledges that neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of any Borrower and its Subsidiaries,
shall be deemed to constitute any representation or warranty by the Agent to any
Lender. Each Lender represents to the Agent that it has, independently and
without

                                      -85-
<PAGE>   92

reliance upon the Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of each Borrower and its Subsidiaries and made
its own decision to make its Loans hereunder and enter into this Agreement.
Each Lender also represents that it will, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of each Borrower and its
Subsidiaries. Except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Agent hereunder or by the other
Loan Documents, the Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, financial and other condition or creditworthiness of any
Borrower and its Subsidiaries which may come into the possession of the Agent
or any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

     Section 13.7   INDEMNIFICATION. The Lenders agree to indemnify the Agent in
its capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to their
respective Commitment Percentages, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including at any time following the payment of the Notes) be imposed on,
incurred by or asserted against the Agent in any way relating to or arising out
of this Agreement or the other Loan Documents, or any documents contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by the Agent under or in connection with
any of the foregoing; PROVIDED that no Lender shall be liable for the payment of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting solely
from the Agent's gross negligence or willful misconduct or resulting solely from
transactions or occurrences that occur at a time after such Lender has assigned
all of its interests, rights and obligations under this Agreement pursuant to
SECTION 12.1 or, in the case of a Lender to which an assignment is made
hereunder pursuant to SECTION 12.1, at a time before such assignment. The
agreements in this subsection shall survive the payment of the Notes, the
Obligations and all other amounts payable hereunder and the termination of this
Agreement.

     Section 13.8   AGENT IN ITS INDIVIDUAL CAPACITY. The Agent and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with any Borrower and its Subsidiaries as if the Agent were not
the Agent hereunder. With respect to its Commitment, the Loans made or renewed
by it and any Note issued to it and any Letter of Credit Guaranty, the Agent
shall have and may exercise the same rights and powers under this Agreement and
the other Loan Documents and is subject to the same obligations and liabilities
as and to the extent set forth herein and in the other Loan Documents for any
other Lender. The terms "Lenders" or "Required Lenders" or any other term shall,
unless the context clearly otherwise indicates, include the Agent in its
individual capacity as a Lender or one of the Required Lenders.

     Section 13.9   SUCCESSOR AGENT. The Agent may resign as Agent upon 5 days
written notice to the Lenders and the Borrowers' Agent; PROVIDED, HOWEVER, that
such resignation shall not take effect until a successor agent has been
appointed. If the Agent shall resign as


                                      -86-
<PAGE>   93


Agent under this Agreement, then the Required Lenders shall appoint from among
the Lenders a successor agent for the Lenders which successor agent shall be
approved by the Borrowers' Agent (which approval shall not be unreasonably
withheld), whereupon such successor agent shall succeed to the rights, powers
and duties of the Agent, and the term "Agent" shall mean such successor agent
effective upon its appointment, and the former Agent's rights, powers and duties
as Agent shall be terminated, without any other or further act or deed on the
part of such former Agent or any of the parties to this Agreement or any holders
of the Notes. If the Required Lenders have failed to appoint a successor agent
within 30 days after the resignation notice given by the Agent as provided
above, then the Agent shall be entitled to appoint a successor agent from among
the Lenders. After any Agent's resignation hereunder as Agent, the provisions of
ARTICLE 13 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under this Agreement.

     Section 13.10  NOTICES FROM AGENT TO LENDERS. The Agent shall promptly,
upon the written request from any Lender, forward to each Lender copies of any
written notices, reports or other information supplied to it by the Borrowers
(but which the Borrowers are not required to supply directly to the Lenders).

     Section 13.11  FIELD EXAMINATION REPORTS; DISCLAIMER BY LENDERS. Each
Lender: (a) is deemed to have requested that the Agent furnish such Lender,
promptly after it becomes available, a copy of each field examination report
(each a "Report" and collectively, "Reports") prepared by the Agent or its
agents; (b) expressly agrees and acknowledges that the Agent makes no
representation or warranty as to the accuracy of any Report or shall be liable
for any information contained in any Report; (c) expressly agrees and
acknowledges that the Reports are not comprehensive audits or examinations, that
the Agent or other party performing any audit or examination will inspect only
specific information regarding the Borrowers and will rely significantly upon
the Borrowers' books and records, as well as on representations of the
Borrowers' personnel; (d) agrees to keep all Reports confidential and strictly
for its internal use, and not to distribute (except to its participants) or use
any Report in any other manner; and (e) without limiting the generality of any
other indemnification provision contained in this Agreement, agrees (i) to hold
the Agent and Deutsche Financial Services Corporation harmless from any action
the indemnifying Lender may take or conclusion the indemnifying Lender may reach
or draw from any Report in connection with any Loans or other credit
accommodations that the indemnifying Lender has made or may make to any
Borrower, or the indemnifying Lender's participation in Letter of Credit
Guarantees, and (ii) to pay and protect, and indemnify, defend and hold the
Agent and Deutsche Financial Services Corporation harmless from and against, the
claims, actions, proceedings, damages, costs, expenses and other amounts
(including, without limitation reasonable attorneys' fees) incurred by the Agent
and Deutsche Financial Services Corporation as the direct or indirect result of
any third parties who might obtain all or part of any Report through the
indemnifying Lender.

                             ARTICLE 14 - GUARANTEE

     Section 14.1   GUARANTEE. The U.S. Borrowers hereby jointly and severally
guarantee to the Agent and the Lenders the prompt payment in full when due
(whether at stated maturity, by acceleration or otherwise) of all Loans made to
the German Borrower and all of the other Obligations of the German Borrower,
including all interest, fees and expenses with respect thereto (collectively,
the "GUARANTEED OBLIGATIONS"). The U.S. Borrowers hereby further jointly and
severally agree that if the German Borrower shall fail to pay in full when due
(whether at stated maturity, by acceleration or otherwise) any of the Guaranteed
Obligations, the U.S. Borrowers will promptly pay the same, without any demand
or notice whatsoever, and that in the case of any extension of time of payment
or renewal of any of the Guaranteed Obligations, the same will be promptly paid
in full when due (whether at extended maturity, by acceleration or otherwise) in
accordance with the terms of such extension or renewal.

     Section 14.2   OBLIGATIONS UNCONDITIONAL. The obligations of the U.S.
Borrowers hereunder are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the German Borrower under this Agreement or any other Loan
Document or any substitution, release or exchange of any other guarantee of or
security for any of the Guaranteed Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever
that might otherwise constitute a legal or equitable discharge or defense of a
surety or guarantor, it being the intent of this SECTION 14.2 that the
obligations of the U.S. Borrowers hereunder shall be absolute and unconditional,
and joint and several, under all circumstances. Without limiting the generality
of the foregoing, it is agreed that each U.S. Borrower's obligations hereunder
shall be absolute and unconditional irrespective of: (a) any lack of validity or
enforceability of any Loan Document or any other agreement or instrument
relating thereto; (b) any change in the time, manner or place of payments of, or
in any other term of, all or any part of the Guaranteed Obligations, or any
other amendment or waiver thereof or any consent to departure therefrom,
including any increase in the Guaranteed Obligations resulting from the
extension of additional credit to the German Borrower or otherwise; (c) any
taking, exchange, release or non-perfection of any collateral, or any release or
amendment or waiver of or consent to departure from any guaranty for all or any
of the Guaranteed Obligations; (d) any change, restructuring or termination of
the corporate structure or existence of any Obligor; or (e) any other
circumstance which might otherwise constitute a defense available to, or a
discharge of, any U.S. Borrower.

     Section 14.3   WAIVER OF SURETYSHIP DEFENSES. Each U.S. Borrower agrees
that the joint and several liability of the U.S. Borrowers provided for in
SECTION 14.1 shall not be impaired or affected by any modification, supplement,
extension or amendment or any contract or agreement to which the other Obligors
may hereafter agree (other than an agreement signed by the Agent and the Lenders
specifically releasing such liability), nor by any delay, extension of time,
renewal, compromise or other indulgence granted by the Agent or any Lender with
respect to any of the Guaranteed Obligations, nor by any other agreements or
arrangements whatever with the other Obligors or with anyone else, each U.S.
Borrower hereby waiving all notice of such delay, extension, release,
substitution, renewal, compromise or other indulgence, and hereby consenting to
be bound thereby as fully and effectually as if it had expressly agreed thereto
in advance. The liability of each U.S. Borrower is direct and unconditional as
to all of the Guaranteed Obligations, and may be enforced without requiring the
Agent or any Lender first to resort to any other right, remedy or security. Each
U.S.


                                      -88-
<PAGE>   95


Borrower hereby expressly waives promptness, diligence, notice of acceptance and
any other notice (except to the extent expressly provided for herein or in
another Loan Document) with respect to any of the Guaranteed Obligations, this
Agreement or any other Loan Document and any requirement that the Agent or any
Lender protect, secure, perfect or insure any Lien or any property subject
thereto or exhaust any right or take any action against the German Borrower or
any other Person or any Collateral, including any rights any U.S. Borrower may
otherwise have under O.C.G.A. ss. 10-7-24 or any successor statute or any
analogous statute in any jurisdiction under the laws of which any U.S. Borrower
is incorporated or in which any U.S. Borrower conducts business.

     Section 14.4   REINSTATEMENT. The obligations of the U.S. Borrowers
hereunder shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Obligor in respect of any of the
Guaranteed Obligations is rescinded or must be otherwise restored by any holder
of any of the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise, and the U.S. Borrowers jointly and
severally agree that they will indemnify each of the Agent and the Lenders on
demand for all reasonable costs and expenses (including fees of counsel)
incurred by the Agent and the Lenders in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

     Section 14.5   REMEDIES. The U.S. Borrowers jointly and severally agree
that, as between the U.S. Borrowers and the Agent and the Lenders, the
Guaranteed Obligations may be declared to be forthwith due and payable as
provided herein (and shall be deemed to have become automatically due and
payable in the circumstances provided herein) for purposes hereof,
notwithstanding any stay, injunction or other prohibition preventing such
declaration (or such Guaranteed Obligations from becoming automatically due and
payable) as against the German Borrower and that, in the event of such
declaration (whether or not the Guaranteed Obligations are then due and payable
by the German Borrower), the Guaranteed Obligations shall forthwith become due
and payable by the U.S. Borrowers for purposes hereof.

     Section 14.6   CONTINUING GUARANTY. The guaranty set forth herein is a
continuing guaranty, and shall apply to all Guaranteed Obligations, whenever and
howsoever arising.

                           ARTICLE 15 - MISCELLANEOUS

     Section 15.1   NOTICES.

     (a)  METHOD OF COMMUNICATION. Except as specifically provided in this
Agreement or in any of the Loan Documents, all notices and the communications
hereunder and thereunder shall be in writing or by telephone subsequently
confirmed in writing. Notices in writing shall be delivered personally or sent
by overnight courier service, by certified or registered mail, postage pre-paid,
return receipt requested, or by facsimile transmission and shall be deemed
received, in the case of personal delivery, when delivered, in the case of
overnight courier service, on the next Business Day after delivery to such

is a day on which deliveries of mail are not made, on the next succeeding day on
which deliveries of mail are made) and, in the case of facsimile transmission,
upon transmittal; provided that in the case of notices to the Agent, the Agent
shall

any of the Loan Documents or the perfection of any rights or security interest
thereunder.

unmatured) and any other indebtedness at any time held or owing by any Lender or
the Issuing Bank to or for the credit or the account of any Borrower against and

such Lender shall have made any demand under this Agreement or any of the Loan
Documents, or (b) the Agent or such Lender shall have declared any or all of the
Obligations to be due and payable as permitted by SECTION 11.2 and although such

ISSUANCE OF A WRIT OF POSSESSION ENTITLING THE LENDER, ITS SUCCESSORS AND
ASSIGNS TO POSSESSION OF THE COLLATERAL UPON DEFAULT OR EVENT OF DEFAULT.
WITHOUT LIMITING THE GENERALITY OF THE FOREGOING AND WITHOUT LIMITING ANY OTHER
RIGHT WHICH THE AGENT OR ANY LENDER MAY HAVE, THE BORROWERS CONSENT THAT, IF THE
AGENT OR ANY LENDER FILES A PETITION FOR AN IMMEDIATE WRIT OF POSSESSION IN

OR IN ACCORDANCE WITH ANY SIMILAR PROVISION OF APPLICABLE LAW. EACH BORROWER
HEREBY ACKNOWLEDGES THAT IT HAS READ AND FULLY UNDERSTANDS THE TERMS OF THIS
WAIVER AND THE EFFECT HEREOF.

     Section 15.7   REVERSAL OF PAYMENTS. To the extent any Borrower makes a
payment or payments to the Agent or any Lender, or the Agent or any Lender
receives any payment or proceeds of the Collateral for any Borrower's benefit,
which payment(s) or proceeds or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside and/or required to be
repaid to a trustee, receiver or any other party under any bankruptcy law, state
or federal law, common law or equitable cause, then, the Agent and each Lender
shall have the continuing and exclusive right to apply, reverse and re-apply any
and all payments to any portion of the Obligations, and, to the extent of such
payment or proceeds received, the Obligations or part thereof intended to be
satisfied shall be revived and continued in full force and effect, as if such
payment or proceeds had not been received by the Agent or such Lender.

     Section 15.8   ACCOUNTING MATTERS. All financial and accounting
calculations, measurements and computations made for any purpose relating to
this Agreement, including, without limitation, all computations utilized by the
Borrowers to determine whether they are in compliance with any covenant
contained herein, shall, unless there is an express written direction or consent
by the Required Lenders to the contrary, be performed in accordance with GAAP.

     Section 15.9   AMENDMENTS.

     (a)  Except as set forth in SUBSECTION (b) below, any term, covenant,
agreement or condition of this Agreement or any of the other Loan Documents may
be amended or waived, and any departure therefrom may be consented to by the
Required Lenders, if, but only if, such amendment, waiver or consent is in
writing signed by the Required Lenders and, in the case of an amendment (other
than an amendment described in SECTION 15.9(d)), by the Borrowers, and


                                      -93-
<PAGE>   100


in any such event, the failure to observe, perform or discharge any such term,
covenant, agreement or condition (whether such amendment is executed or such
waiver or consent is given before or after such failure) shall not be construed
as a breach of such term, covenant, agreement or condition or as a Default or an
Event of Default; PROVIDED that (i) without the written consent of the Agent, no
amendment or waiver shall be made to any provision of SECTION 2A.6 hereof or any
of the Agent's rights or obligations with respect to Letter of Credit
Guarantees, (ii) without the written consent of the Agent, no amendment or
waiver shall be made to any of the Agent's rights or obligations with respect to
Non-Ratable Loans, and (iii) without the written consent of the Agent, no
amendment or waiver shall be made to any provision of ARTICLE 13 as such
provisions apply to the Agent or to any other provision of any Loan Document as
such provisions relate to the rights and obligations of the Agent. Unless
otherwise specified in such waiver or consent, a waiver or consent given
hereunder shall be effective only in the specific instance and for the specific
purpose for which given.

     (b)  Except as otherwise set forth in this Agreement, without the prior
unanimous written consent of the Lenders, (i) no amendment, consent or waiver
shall affect the amount or extend the time of the obligation of the Lenders to
make Loans, extend the originally scheduled time or times of payment of the
principal of any Loan, alter the time or times of payment of interest on any
Loan or the amount of the principal thereof or the rate of interest thereon or
the amount of any commitment fee payable hereunder, permit any subordination of
the principal or interest on any Loan, permit the subordination of the Security
Interests in any material Collateral (meaning Collateral having a then fair
market value in excess of $1,000,000), or amend the provisions of ARTICLE 11 or
of this SECTION 15.9(b), (ii) no material Collateral (meaning Collateral having
a then fair market value in excess of $1,000,000) shall be released by the Agent
other than releases of Collateral in connection with the sale of any such
Collateral in the ordinary course of the Borrowers' business or as otherwise
specifically permitted in this Agreement, (iii) no amendment shall be made to
the definitions of "Commitment", "Commitment Percentage", "Equipment Acquisition
Loan Limit", "Proportionate", "Ratable", "Required Lenders" or "Obligations",
(iv) neither the Agent nor any Lender shall consent to any amendment to or
waiver of the amortization, deferral or subordination provisions of any
Subordinated Indebtedness or any other instrument or agreement evidencing or
relating to obligations of the Borrowers that are expressly subordinate to any
of the Obligations if such amendment or waiver would be adverse to the Lenders
in their capacities as Lenders hereunder; and (v) no amendment shall be made
that increases the advance rates set forth in the definition of "Borrowing
Base"; PROVIDED, HOWEVER, that anything herein to the contrary notwithstanding,
the Required Lenders shall have the right to waive any Default or Event of
Default (unless such Default or Event of Default arises out of a provision of
this Agreement which can only be amended with the unanimous consent of the
Lenders) and the consequences hereunder of such Default or Event of Default and
shall have the right to enter into an agreement with the Borrowers providing for
the forbearance from the exercise of any remedies provided hereunder or under
the other Loan Documents without waiving any Default or Event of Default.

     (c)  The making of Loans hereunder by the Lenders (or the issuance of
Letter of Credit Guarantees) during the existence of a Default or Event of
Default shall not be deemed to constitute a waiver of such Default or Event of
Default.

     (d)  Notwithstanding any provision of this Agreement or any other Loan
Document to the contrary, no consent, written or otherwise, of any Borrower
shall be necessary or required in connection with any amendment to ARTICLE 13 or
SECTION 3.7, and any amendment to such provisions


                                      -94-
<PAGE>   101


shall be effected solely by and among the Agent and the Required Lenders (or
Lenders, as the case may be), PROVIDED that no such amendment shall impose any
obligation on any Borrower.

     Section 15.10  PERFORMANCE OF BORROWERS' DUTIES. The Borrowers' obligations
under this Agreement and each of the Loan Documents shall be performed by the
Borrowers at their sole cost and expense. If the Borrowers shall fail to do any
act or thing which they have covenanted to do under this Agreement or any of the
Loan Documents, the Agent, on behalf of the Lenders, may (but shall not be
obligated to), after notice to the Borrowers' Agent, do the same or cause it to
be done either in the name of the Agent or in the name and on behalf of the
Borrowers, and the Borrowers hereby irrevocably authorize the Agent so to act.

     Section 15.11  INDEMNIFICATION. The Borrowers jointly and severally agree
to reimburse the Agent and the Lenders for all costs and expenses, including
reasonable counsel fees and disbursements, incurred, and to indemnify and hold
the Agent and the Lenders harmless from and against all losses suffered by, the
Agent or any Lender in connection with (a) the exercise by the Agent or any
Lender of any right or remedy granted to it under this Agreement or any of the
Loan Documents, (b) any claim, and the prosecution or defense thereof, arising
out of or in any way connected with this Agreement or any of the Loan Documents,
including without limitation any claim relating to Environmental Laws, and (c)
the collection or enforcement of the Obligations or any of them, other than such
costs, expenses and liabilities arising out of the Agent's or such Lender's
gross negligence or willful misconduct.

     Section 15.12  ALL POWERS COUPLED WITH INTEREST. All powers of attorney and
other authorizations granted to the Agent or any Lender and any Persons
designated by the Agent or any Lender pursuant to any provisions of this
Agreement or any of the Loan Documents shall be deemed coupled with an interest
and shall be irrevocable so long as any of the Obligations remain unpaid or
unsatisfied or the Revolving Credit Facility has not been terminated.

     Section 15.13  SURVIVAL. Notwithstanding any termination of this Agreement,
(a) until the Revolving Credit Facility and the Equipment Acquisition Loan
Facility have been terminated and all Obligations payable on or prior to such
termination have been paid in full, the Agent and each Lender shall retain its
Security Interest and shall retain all rights under this Agreement and each of
the Security Documents with respect to the Collateral as fully as though this
Agreement had not been terminated, and (b) the indemnities to which the Agent
and each Lender is entitled under the provisions of this ARTICLE 15 and any
other provision of this Agreement and the Loan Documents shall continue in full
force and effect and shall protect the Agent and each Lender against events
arising after such termination as well as before.

     Section 15.14  SEVERABILITY OF PROVISIONS. Any provision of this Agreement
or any other Loan Document which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective only to the extent
of such prohibition or unenforceability without invalidating the remainder of
such provision or the remaining provisions hereof or thereof or affecting the
validity or enforceability of such provision in any other jurisdiction.

     Section 15.15  GOVERNING LAW. This Agreement and the Note shall be
construed in accordance with and governed by the law of the State of Georgia.

     Section 15.16  COUNTERPARTS. This Agreement may be executed in any number
of counterparts and by different parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and shall be binding
upon all parties, their successors and assigns, and all of which taken together
shall constitute one and the same agreement.

     Section 15.17  REPRODUCTION OF DOCUMENTS. This Agreement, each of the Loan
Documents and all documents relating thereto, including, without limitation, (a)
consents, waivers and modifications that may hereafter be executed, (b)
documents received by the Agent or any Lender, and (c) financial statements,
certificates and other information previously or hereafter furnished to the
Agent or any Lender, may be reproduced by the Agent or any Lender by any
photographic, photostatic, microcard, microfilm, miniature photographic or other
similar process, and the Agent or any Lender may destroy any original document
so reproduced. Each party hereto stipulates that, to the extent permitted by
applicable laws any such reproduction shall be as admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original shall be in existence and whether or not such reproduction was made by
the Agent or such Lender in the regular course of business), and any
enlargement, facsimile or further reproduction of such reproduction shall
likewise be admissible in evidence.

     Section 15.18  NO ORAL AGREEMENTS. ORAL AGREEMENTS OR COMMITMENTS TO LEND
MONEY, EXTEND CREDIT OR TO FORBEAR FROM ENFORCING REPAYMENT OF A DEBT, INCLUDING
PROMISES TO EXTEND OR RENEW SUCH DEBT, ARE NOT ENFORCEABLE. TO PROTECT THE
BORROWERS, THE AGENT AND EACH LENDER FROM MISUNDERSTANDING OR DISAPPOINTMENT,
ANY AGREEMENTS SUCH PARTIES REACH COVERING SUCH MATTERS ARE CONTAINED IN THIS
WRITING, WHICH IS THE COMPLETE AND EXCLUSIVE STATEMENT OF THE AGREEMENT BETWEEN
SUCH PARTIES, EXCEPT AS SUCH PARTIES MAY LATER AGREE IN WRITING TO MODIFY IT.
THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN SUCH PARTIES. The Agent may, from time
to time, announce in writing to the Borrowers its policies and procedures
regarding its administration of this Agreement, including, without limitation,
the Agent's fees and/or charges for transfers of funds to or from the Borrowers,
including electronic transfers; any subsequent use by any Borrower of this
facility following any such announcement shall constitute the Borrowers'
acceptance of such revised policies and procedures.

     Section 15.19  USE OF COUNSEL AND RECEIPT OF AGREEMENT. Each Borrower
acknowledges that it has received a true and complete copy of this Agreement.
Each Borrower further acknowledges that it has (a) had representation of counsel
during negotiation of this Agreement, and (b) read and understood this
Agreement.

     Section 15.20  FACSIMILES, ETC. Notwithstanding anything herein to the
contrary: (a) the Agent and each Lender may rely on any facsimile copy,
electronic data transmission or electronic data storage of any statement,
financial statements or other reports, and (b) such facsimile copy, electronic
data transmission or electronic data storage will be deemed an original, and the
best evidence thereof for all purposes, including, without limitation, under
this Agreement or any other Loan Document, and for all evidentiary purposes
before any arbitrator, court or other adjudicatory authority.

     Section 15.21  PRO-RATA PARTICIPATION.


                                      -96-
<PAGE>   103


     (a)  Each Lender agrees that if, as a result of the exercise of a right of
setoff, banker's lien or counterclaim or other similar right or the receipt of a
secured claim it receives any payment in respect of the Obligations, it shall
promptly notify the Agent thereof (and the Agent shall promptly notify the other
Lenders). If, as a result of such payment, such Lender receives a greater
percentage of the Obligations owed to it under this Agreement than the
percentage received by any other Lender, such Lender shall purchase a
participation (which it shall be deemed to have purchased simultaneously upon
the receipt of such payment) in the Obligations then held by such other Lenders
so that all such recoveries of principal and interest with respect to all
Obligations owed to each Lender shall be pro rata on the basis of its respective
amount of the Obligations owed to all Lenders, PROVIDED that if all or part of
such proportionately greater payment received by such purchasing Lender is
thereafter recovered by or on behalf of any Borrower from such Lender, such
purchase shall be rescinded and the purchase price paid for such participation
shall be returned to such Lender to the extent of such recovery, but without
interest.

     (b)  Each Lender which receives such a secured claim shall exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Lenders entitled under this SECTION 15.21 to share in the benefits of any
recovery on such secured claim.

     (c)  Each Borrower expressly consents to the foregoing arrangements and
agrees that any holder of a participation in any Obligation so purchased or
otherwise acquired may exercise any and all rights of banker's lien, set-off or
counterclaim with respect to any and all monies owing by such Borrower to such
holder as fully as if such holder were a holder of such Obligation in the amount
of the participation held by such holder.

     Section 15.22  JUDGMENT CURRENCY.

     (a)  If for the purposes of obtaining judgment in any court it is necessary
to convert a sum due hereunder or under the Notes in any currency (the "ORIGINAL
CURRENCY") into another currency (the "OTHER CURRENCY") the parties hereto
agree, to the fullest extent that they may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal banking
procedures the Agent could purchase the Original Currency with the Other
Currency at 11:00 A.M. on the second Business Day preceding that on which final
judgment is given.

     (b)  The obligation of an Obligor in respect of any sum due in the Original
Currency from it to any Lender or the Agent hereunder or under the Notes held by
such Lender shall, notwithstanding any judgment in any Other Currency, be
discharged only to the extent that on the Business Day following receipt by such
Lender or the Agent (as the case may be) of any sum adjudged to be so due in
such Other Currency such Lender or the Agent (as the case may be) may in
accordance with normal banking procedures purchase the Original Currency with
such Other Currency. If the amount of the Original Currency so purchased is less
than the sum originally due to such Lender or the Agent (as the case may be) in
the Original Currency, such Obligor agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify such Lender or the Agent (as the
case may be) against such loss, and if the amount of the Original Currency so
purchased exceeds the sum originally due to any Lender or the Agent (as the case
may be) in the Original Currency, such Lender or the Agent (as the case may be)
agrees to remit to such Obligor such excess.

     Section 15.23  RELEASES.

     (a)  The Agent and each Lender (collectively, the "Secured Parties") agree
that sales, transfers or other dispositions (whether in a single transaction or
a series of related transactions and whether by merger, consolidation or
otherwise) permitted (or not prohibited) hereunder, or under any other Loan
Document, of all or any part of the Collateral or any other assets or properties
of any Borrower or any of its Subsidiaries (including, without limitation,
mergers, consolidations and asset sales permitted (or not prohibited) by CLAUSE
(a) of SECTION 10.7 hereof) shall, provided the proceeds thereof are paid to the
Agent in accordance with the terms of this Agreement, be free and clear of all
Liens therein held by any Secured Party and shall not, except as set forth in
this Agreement, require any written or oral release (including, without
limitation, any release or termination of any Lien therein held by any Secured
Party) or consent by or of, or notice to, any Secured Party or any other Person.
Notwithstanding the foregoing, each Secured Party agrees that without notice to
or consent by or of such Person (i) the Borrowers' Agent may, on behalf of any
Borrower or any of its Subsidiaries, request the Agent to, on behalf of each
Secured Party, execute and deliver to the Borrowers' Agent, for the benefit of
any Person, a written release, disclaimer, termination or quitclaim, and such
other release documents as the Borrowers' Agent may reasonably request, of all
Liens held by any Secured Party in such assets or properties described in the
preceding sentence, and such Person shall be entitled to rely conclusively on
such release, disclaimer, termination, quitclaim or other release document, and
(ii) the Agent may execute and deliver any such document.

     (b)  Upon the termination of Leisegang's obligations under this Agreement
pursuant to and in accordance with SECTION 10.7, each Secured Party agrees that
without notice to or consent by or of such Person (i) the Borrowers' Agent, on
behalf of any Borrower or any of its Subsidiaries, may request the Agent to, on
behalf of each Secured Party, (A) execute and deliver to the Borrowers' Agent,
for the benefit of Leisegang, (1) a written release, disclaimer, termination or
quitclaim, and such other release documents as the Borrowers' Agent may
reasonably request, of all Liens held by any Secured Party in the assets of
Leisegang, and (2) a written release and termination of Leisegang's obligations
under all Loan Documents executed by Leisegang, and Leisegang shall be entitled
to rely conclusively on such releases, disclaimers, terminations, quitclaims and
other release documents, and (B) deliver any assets of Leisegang in the
possession of the Agent to the Borrowers' Agent, and (ii) the Agent may execute
and deliver such documents and assets.

     (c)  Each request or instruction delivered to the Agent pursuant to clause
(a) or (b) above (each such request or instruction, a "Release Request") shall
(i) be in writing signed by an authorized officer of the Borrowers' Agent, (ii)
describe the property permitted to be released or delivered in reasonable
detail, (iii) certify that such Release Request relates to a sale, transfer or
other disposition permitted (or not prohibited) by the Loan Documents, and (iv)
certify that all proceeds from such sale, transfer or disposition have been paid
to the Agent pursuant to and in accordance with the terms of this Agreement.
Within ten Business Days after the Agent's receipt of a Release Request with
respect to a transaction for which a Release Request is properly made under this
SECTION 15.23, the Agent, on behalf of each Secured Party, shall (i) deliver to
the Borrower's Agent the requested property in the possession of the Agent, and
(ii) execute and deliver to the Borrower's Agent the releases, disclaimers,
terminations, quitclaims and other release documents described in CLAUSES (a)
and (b), to the extent properly requested by the Borrowers' Agent.


                                      -98-
<PAGE>   105


     (d)  All notices, requests, instructions, statements, directions, consents
and certificates requested under or required by this Section 15.23 shall be full
authority for and direction to the Agent to, on behalf of each Secured Party,
(i) execute and deliver to the Borrower's Agent the releases, disclaimers,
terminations, quitclaims and other release documents referred to in this Section
15.23, and (ii) deliver any property required to be delivered to the Borrower's
Agent pursuant to this Section 15.23.

     (e)  Nothing set forth in this SECTION 15.23 shall constitute the release
of any Collateral, other assets or Obligor, or require the Agent to execute any
releases or other documents with respect to the release of any Collateral, other
assets or Obligor, except to the extent that (i) any sale, transfer or other
disposition contemplated hereby is permitted by, and made in accordance with,
the terms of this Agreement, and (ii) the proceeds of such sale, transfer or
other disposition are paid to the Agent in accordance with the terms of this
Agreement.

     (f)  The Borrowers shall be jointly and severally liable for all of the
reasonable costs and expenses incurred by the Agent in connection with this
SECTION 15.23 and the Agent's execution and delivery of any of the documents and
assets described herein, including, without limitation, the reasonable fees and
expenses of the Agent's legal counsel.

     Section 15.24  WAIVER OF CONSEQUENTIAL DAMAGES, ETC.. EACH PARTY HERETO
AGREES NOT TO ASSERT ANY CLAIM AGAINST ANY OTHER PARTY HERETO, ANY OF ITS
AFFILIATES, OR ANY OF ITS DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS OR AGENTS,
ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE
DAMAGES ARISING OUT OF OR OTHERWISE RELATING TO ANY OF THE TRANSACTIONS
CONTEMPLATED HEREIN OR IN ANY OTHER LOAN DOCUMENT OR THE ACTUAL OR PROPOSED USE
OF THE PROCEEDS OF THE LOANS.

                  GALILEO CORPORATION CHANGES NAME TO NETOPTIX
                      CORPORATION AND NASDAQ SYMBOL TO OPTX

STURBRIDGE, MASSACHUSETTS, September 30, 1999 - Galileo Corporation (Nasdaq:
GAEO) announced today that it has changed its name to NetOptix Corporation
effective immediately. The Company's new Nasdaq trading symbol is OPTX effective
on October 1, 1999.

The name change was made in recognition of the emergence of the Company
primarily as a manufacturer of optical telecommunications components and its
focus on developing and manufacturing Dense Wavelength Division Multiplex (DWDM)
optical filters. These filters are a key component in fiber optic communications
systems to split a single fiber optic channel into multiple wavelengths, thereby
permitting a substantial increase in communications capacity. The need for
increased capacity stems from the surge in demand fueled, in part, by the growth
of Internet traffic.

As previously announced, the Company's subsidiary, Optical Filter Corporation
(OFC), which has developed and is now manufacturing and marketing DWDM optical
filters, recently received its first production order for this product. OFC also
produces a broad range of optically coated products and operates a
state-of-the-art diamond point turning facility.

The Company's other subsidiary, Leisegang Medical, Inc., develops, manufactures
and distributes women's health-related medical products, including colposcopes
and a variety of diagnostic and surgical devices.
