                          THE REVOLVING CREDIT FACILITY

         II.1.    LOANS.

                  (a COMMITMENT. Subject to the terms and conditions of this
Agreement, the Lender agrees to make Advances to the Borrowers under the
Revolving Credit Facility from time to time from the Closing Date until the
Revolving Credit Termination Date up to but not exceeding the Revolving Credit
Commitment, PROVIDED, however, that the Lender will not be required and shall
have no obligation to make any such Advance (i) so long as a Default or an Event
of Default has occurred and is continuing or (ii) if the Lender has accelerated
the maturity of the Note as a result of an Event of Default; PROVIDED further,
however, that immediately after giving effect to each such Advance, the
principal amount of Revolving Credit Outstandings plus Letter of Credit
Outstandings shall not exceed the Revolving Credit Commitment. Within such
limits, the Borrowers may borrow, repay and reborrow under the Revolving Credit
Facility on a Business Day from the Closing Date until, but (as to borrowings
and reborrowings) not including, the Revolving Credit Termination Date;
PROVIDED, however, that (y) no Loan that is a Eurodollar Rate Loan shall be made
which has an Interest Period that extends beyond the Stated Termination Date and
(z) each Loan that is a Eurodollar Rate Loan may, subject to the provisions of
SECTION 2.6, be repaid only on the last day of the Interest Period with respect
thereto unless such payment is accompanied by the additional payment, if any,
required by SECTION 4.5. Notwithstanding the foregoing, the sum of outstanding
Loans made to and Letters of Credit issued for the benefit of TTI and WFI, and
in the case of Letters of Credit those issued for the benefit of any Subsidiary
of TTI or WFI, shall at no time exceed $5,000,000.

                  (b AMOUNTS. Except as otherwise permitted by the Lender from
time to time, the aggregate unpaid principal amount of the Revolving Credit
Outstandings plus Letter of Credit Outstandings shall not exceed at any time the
Revolving Credit Commitment, and, in the event there shall be outstanding any
such excess, the Borrowers shall immediately make such payments and prepayments
as shall be necessary to comply with this restriction. Each Loan hereunder,
other than Base Rate Refunding Loans, and each conversion under SECTION 2.7,
shall be in an amount of at least $100,000, and, if greater than $100,000, an
integral multiple of $100,000.

                  (c ADVANCES. (i) An Authorized Representative shall give the
Lender (1) at least three (3) Business Days' irrevocable written notice by
telefacsimile transmission of a Borrowing Notice or Interest Rate Selection
Notice (as applicable) with appropriate insertions, effective upon receipt, of
each Loan that is a Eurodollar Rate Loan (whether representing an additional
borrowing hereunder or the conversion of a borrowing hereunder from Base Rate
Loans to Eurodollar Rate Loans) prior to 10:30 A.M. and (2) irrevocable written
notice by telefacsimile transmission of a Borrowing Notice or Interest Rate
Selection Notice (as applicable) with appropriate insertions, effective upon
receipt, of each Loan (other than Base Rate Refunding Loans to the extent the
same are effected without notice pursuant to SECTION 2.1(C)(IV)) that is a Base
Rate Loan (whether representing an additional borrowing hereunder or the
conversion of borrowing hereunder from Eurodollar Rate Loans to Base Rate Loans)
prior to 10:30 A.M. on the day of such proposed Loan.

                                       23
<PAGE>

Each such notice shall specify the amount of the borrowing, the type of Loan
(Base Rate or Eurodollar Rate), the date of borrowing and, if a Eurodollar Rate
Loan, the Interest Period to be used in the computation of interest.

         (ii) Not later than 2:00 P.M. on the date specified for each borrowing
under this SECTION 2.1, the Lender shall, pursuant to the terms and subject to
the conditions of this Agreement, make the amount of the Advance or Advances
available to the Borrowers by delivery of the proceeds thereof to the Borrowers'
Account or otherwise as shall be directed in the applicable Borrowing Notice by
the Authorized Representative and reasonably acceptable to the Lender.

         (iii) The Borrowers shall have the option to elect the duration of the
initial and any subsequent Interest Periods and to Convert the Loans in
accordance with SECTION 2.7. Eurodollar Rate Loans and Base Rate Loans may be
outstanding at the same time, PROVIDED, HOWEVER, there shall not be outstanding
at any one time Eurodollar Rate Loans having more than five (5) different
Interest Periods. If the Lender does not receive a Borrowing Notice or an
Interest Rate Selection Notice giving notice of election of the duration of an
Interest Period or of Conversion of any Loan to or Continuation of a Loan as a
Eurodollar Rate Loan by the time prescribed by SECTION 2.1(C) OR 2.7, the
Borrowers shall be deemed to have elected to Convert such Loan to (or Continue
such Loan as) a Base Rate Loan until the Borrowers notify the Lender in
accordance with SECTION 2.7.

         (iv) Notwithstanding the foregoing, if a drawing is made under any
Letter of Credit, such drawing is honored by the Issuing Bank prior to the
Stated Termination Date, and the Borrowers shall not immediately fully reimburse
the Issuing Bank in respect of such drawing, (A) provided that the conditions to
making a Loan as herein provided shall then be satisfied, the Reimbursement
Obligation arising from such drawing shall be paid to the Issuing Bank by the
Lender without the requirement of notice to or from the Borrowers from
immediately available funds which shall be advanced as a Base Rate Refunding
Loan by the Lender under the Revolving Credit Facility, and (B) if the
conditions to making a Loan as herein provided shall not then be satisfied, the
Lender shall fund by payment to the Issuing Bank in immediately available funds
the purchase price from the Issuing Bank of the Reimbursement Obligation. Any
such Base Rate Refunding Loan shall be advanced as, and shall continue as, a
Base Rate Loan unless and until the Borrowers Convert such Base Rate Loan in
accordance with the terms of SECTION 2.7.

                  (d Except as provided in SECTION 2.1(E), each Borrower shall
be jointly and severally liable as primary obligor and not merely as surety for
repayment of all Obligations arising under the Loan Documents. Such joint and
several liability shall apply to each Borrower regardless of whether (i) any
Loan was only requested on behalf of or made to another Borrower or the proceeds
of any Loan were used only by another Borrower, (ii) any Letter of Credit was
issued on the application of another Borrower, (iii) any interest rate election
was made only on behalf of another Borrower, or (iv) any indemnification
obligation or any other obligation arose only as a result of the actions of
another Borrower; PROVIDED the liability of each of the Borrowers other than the
Parent under this Agreement, the Notes and the other Loan Documents shall be
limited to the maximum amount of the Obligations under the Revolving Credit
Facility for which such other Borrower may be liable without violating any
applicable fraudulent conveyance, fraudulent transfer or comparable laws. Each
Borrower shall retain any right of contribution arising under applicable law
against the

                                       24
<PAGE>

other Borrowers as the result of the satisfaction of any Obligations; PROVIDED,
no Borrower shall assert such right of contribution against any other Borrower
until the Obligations shall have been paid in full.

         Without limiting the foregoing provisions of this SECTION 2.1(D), the
Parent, hereby irrevocably, absolutely and unconditionally guarantees the full
and punctual payment or performance when due, whether at stated maturity, by
required prepayment, declaration, acceleration, demand or otherwise, of all
Obligations of each other Borrower owing to the Lender. This guarantee
constitutes a guaranty of payment and not of collection.

         It is the intention of the parties that with respect to the Parent its
obligations under the immediately preceding paragraph shall be absolute,
unconditional and irrevocable irrespective of:

                           (i) any lack of validity, legality or enforceability
                  of this Agreement, any Note, or any other Loan Document as to
                  any other Borrower;

                           (ii) the failure of the Lender:

                                    (A) to enforce any right or remedy against
                           any other Borrower or any other Person under the
                           provisions of this Agreement, any Note, any other
                           Loan Document or otherwise, or

                                    (B) to exercise any right or remedy against
                           any guarantor of, or collateral securing, any
                           Obligations;

                           (iii) any change in the time, manner or place of
         payment of, or in any other term of, all or any of the Obligations, or
         any other extension, compromise or renewal of any Obligations with
         respect to any other Borrower;

                           (iv) any reduction, limitation, impairment or
         termination of any Obligations with respect to any other Borrower or
         any other Person for any reason including any claim of waiver, release,
         surrender, alteration or compromise, and shall not be subject to (and
         the Parent hereby waives any right to or claim of) any defense or
         setoff, counterclaim, recoupment or termination whatsoever by reason of
         the invalidity, illegality, nongenuineness, irregularity, compromise or
         unenforceability of, or any other event or occurrence affecting, any
         Obligations with respect to any other Borrower;

                           (v) any addition, exchange, release, surrender or
         nonperfection of any collateral, or any amendment to or waiver or
         release or addition of, or consent to departure from , any guaranty,
         held by the Lender or any holder of any Note securing any of the
         Obligations; or

                           (vi) any other circumstance which might otherwise
         constitute a defense available to, or a legal or equitable discharge
         of, any other Borrower, any surety or any guarantor.

         The Parent agrees that its joint and several liability hereunder shall
continue to be effective or be reinstated, as the case may be, if at any time
any payment (in whole or in part) of any of the Obligations is rescinded or must
be restored by the Lender or any holder of any Note, upon the

                                       25
<PAGE>

insolvency, bankruptcy or reorganization of any other Borrower as though such
payment had not been made.

         Each Borrower hereby expressly waives: (a) notice of the Lender's
acceptance of this Agreement; (b) notice of the existence or creation or
non-payment of all or any of the Obligations; (c) presentment, demand, notice of
dishonor, protest, and all other notices whatsoever other than notices expressly
provided for in this Agreement or by applicable law and (d) all diligence in
collection or protection of or realization upon the Obligations or any thereof,
any obligation hereunder, or any security for or guaranty of any of the
foregoing.

         No delay on any of the Lender's part in the exercise of any right or
remedy shall operate as a waiver thereof, and no single or partial exercise by
the Lender of any right or remedy shall preclude any other or further exercise
thereof or the exercise of any other right or remedy. No action of the Lender
permitted hereunder shall in any way affect or impair any of its rights or any
of its obligations to any of the Borrowers under this Agreement (except as
otherwise waived, modified, or amended).

                  (e) Notwithstanding anything herein to the contrary, TTI and
WFI shall be liable hereunder only for Advances, Loans and Reimbursement
Obligations made to it or on its behalf hereunder together with interest
relating thereto and fees and expenses arising hereunder.

         II.2. PAYMENT OF INTEREST. (a The Borrowers shall pay interest to the
Lender on the outstanding and unpaid principal amount of each Loan for the
period commencing on the date of such Loan until such Loan shall be due at the
then applicable Base Rate for Base Rate Loans or applicable Eurodollar Rate for
Eurodollar Rate Loans, as designated by the Authorized Representative pursuant
to SECTION 2.1; PROVIDED, however, that if any amount shall not be paid when due
(at maturity, by acceleration or otherwise), all amounts outstanding hereunder
shall bear interest thereafter at the Default Rate.

                  (b Interest on each Loan shall be computed on the basis of a
year of 360 days and calculated in each case for the actual number of days
elapsed. Interest on each Loan shall be paid (i) quarterly in arrears not later
than three (3) Business Days following the last Business Day of each March,
June, September and December, commencing June 30, 1999 for each Base Rate Loan,
(ii) on the last day of the applicable Interest Period for each Eurodollar Rate
Loan and, if such Interest Period extends for more than three (3) months, at
intervals of three (3) months after the first day of such Interest Period, and
(iii) upon payment in full of the principal amount of such Loan.

         II.3. PAYMENT OF PRINCIPAL. The principal amount of each Loan shall be
due and payable to the Lender in full on the Revolving Credit Termination Date,
or earlier as specifically provided herein. The principal amount of any Base
Rate Loan may be prepaid in whole or in part at any time. The principal amount
of any Eurodollar Rate Loan may be prepaid only at the end of the applicable
Interest Period unless the Borrowers shall pay to the Lender the additional
amount, if any, required under SECTION 4.5. All prepayments of Loans made by the
Borrowers shall be in the amount of $100,000 or such greater amount which is an
integral multiple of $100,000, or the amount equal to all Revolving Credit
Outstandings, or such other amount as necessary to comply with SECTION 2.1(B) or
SECTION 2.7.

                                       26
<PAGE>

         II.4. NON-CONFORMING PAYMENTS. (a Each payment of principal (including
any prepayment) and payment of interest and fees, and any other amount required
to be paid to the Lender with respect to the Loans, shall be made to the Lender
at the Principal Office in Dollars and in immediately available funds before
12:30 P.M. on the date such payment is due. The Lender may, but shall not be
obligated to, debit the amount of any such payment which is not made by such
time to any ordinary deposit account, if any, of the Borrowers with the Lender.

         (b The Lender shall deem any payment made by or on behalf of the
Borrowers hereunder that is not made both in Dollars and in immediately
available funds and prior to 12:30 P.M. to be a non-conforming payment. Any such
payment shall not be deemed to be received by the Lender until the later of (i)
the time such funds become available funds and (ii) the next Business Day. Any
non-conforming payment may constitute or become a Default or Event of Default.
Interest shall continue to accrue on any principal as to which a non-conforming
payment is made until the later of (x) the date such funds become available
funds or (y) the next Business Day at the Default Rate from the date such amount
was due and payable.

         (c In the event that any payment hereunder or under the Note becomes
due and payable on a day other than a Business Day, then such due date shall be
extended to the next succeeding Business Day unless provided otherwise under
clause (ii) of the definition of "Interest Period"; PROVIDED that interest shall
continue to accrue during the period of any such extension and PROVIDED further,
that in no event shall any such due date be extended beyond the Revolving Credit
Termination Date.

         II.5. NOTES. Loans made or Continued by the Lender pursuant to the
terms and conditions of this Agreement shall be evidenced by the Note payable to
the order of the Lender in the amount of the Revolving Credit Commitment, which
Note shall be dated the Closing Date and shall be duly completed, executed and
delivered by the Borrowers.

         II.6. REDUCTIONS. The Borrowers shall, by notice from an Authorized
Representative, have the right from time to time but not more frequently than
once each calendar month, upon not less than three (3) Business Days' written
notice to the Lender, effective upon receipt, to reduce the Revolving Credit
Commitment. Each such reduction shall be in the aggregate amount of $500,000 or
such greater amount which is in an integral multiple of $100,000, or the entire
remaining Revolving Credit Commitment, and shall permanently reduce the
Revolving Credit Commitment. Each reduction of the Revolving Credit Commitment
shall be accompanied by payment of the Loans to the extent that the principal
amount of Revolving Credit Outstandings plus Letter of Credit Outstandings
exceeds the Revolving Credit Commitment after giving effect to such reduction,
together with accrued and unpaid interest on the amounts prepaid. No such
reduction shall result in the payment of any Eurodollar Rate Loan other than on
the last day of the Interest Period of such Eurodollar Rate Loan unless such
prepayment is accompanied by amounts due, if any, under SECTION 4.5.

         II.7. CONVERSIONS AND ELECTIONS OF SUBSEQUENT INTEREST PERIODS. Subject
to the limitations set forth below and in ARTICLE IV, the Borrowers may:

                                       27
<PAGE>

                  (a upon delivery, effective upon receipt, of a properly
completed Interest Rate Selection Notice to the Lender on or before 10:30 A.M.
on any Business Day, Convert all or a part of Eurodollar Rate Loans to Base Rate
Loans on the last day of the Interest Period for such Eurodollar Rate Loans; and

                  (b provided that no Default or Event of Default shall have
occurred and be continuing and upon delivery, effective upon receipt, of a
properly completed Interest Rate Selection Notice to the Lender on or before
10:30 A.M. three (3) Business Days' prior to the date of such election or
Conversion:

                           (i) elect a subsequent Interest Period for all or a
                  portion of Eurodollar Rate Loans to begin on the last day of
                  the then current Interest Period for such Eurodollar Rate
                  Loans; and

                           (ii) Convert Base Rate Loans to Eurodollar Rate Loans
                  on any Business Day.

         Each election and Conversion pursuant to this SECTION 2.7 shall be
subject to the limitations on Eurodollar Rate Loans set forth in the definition
of "Interest Period" herein and in SECTIONS 2.1, 2.3 and ARTICLE IV.

         II.8. INCREASE AND DECREASE IN AMOUNTS. The amount of the Revolving
Credit Commitment which shall be available to the Borrowers as Advances shall be
reduced by the aggregate amount of Outstanding Letters of Credit.

         II.9. UNUSED FEE. For the period beginning on the Closing Date and
ending on the Revolving Credit Termination Date, the Borrowers agree to pay to
the Lender an unused fee equal to the Applicable Unused Fee multiplied by the
average daily amount by which the Revolving Credit Commitment exceeds the sum of
(i) Revolving Credit Outstandings plus (ii) Letter of Credit Outstandings. Such
fees shall be due in arrears not later than three (3) Business Days following
the last Business Day of each March, June, September and December commencing
June 30, 1999 to and on the Revolving Credit Termination Date (or such earlier
date as the Lenders refuse to fund hereunder).

         II.10. USE OF PROCEEDS. The proceeds of the Loans made pursuant to the
Revolving Credit Facility hereunder shall be used by the Borrowers to repay
Indebtedness outstanding under the Prior Agreements, for general working capital
needs and other corporate purposes, including the making of Acquisitions and
Capital Expenditures permitted hereunder.

                                   ARTICLE III

                                LETTERS OF CREDIT

         III.1. LETTERS OF CREDIT. The Issuing Bank agrees, subject to the terms
and conditions of this Agreement, upon request of the Borrowers to issue from
time to time for the account or benefit of the Parent or any of its
Subsidiaries, Letters of Credit upon delivery to the Issuing Bank of an
Application and Agreement for Letter of Credit relating thereto in form and
content acceptable to the Issuing Bank; PROVIDED, that if a Letter of Credit is
to be issued for the account or benefit of a Subsidiary of the Parent other than
TTI or WFI, both the Parent and such Subsidiary jointly and severally as
co-applicants shall deliver to the Issuing Bank an Application and Agreement for
Letter of Credit, and PROVIDED FURTHER, that (i) the Letter of Credit
Outstandings shall not exceed the Letter of Credit Commitment and (ii) no Letter
of Credit shall be issued if, after giving effect thereto, Letter of Credit
Outstandings plus Revolving Credit Outstandings shall exceed the Revolving
Credit Commitment. No Letter of Credit shall have an expiry date (including all
rights of the Borrowers or any Subsidiary named in such Letter of Credit to
require renewal) or payment date occurring later than the earlier to occur of
(A) one year after the date of its issuance with respect to Standby Letters of
Credit or one hundred eighty days after the date of its issuance with respect to
Documentary Letters of Credit; or (B) the fifth Business Day prior to the Stated
Termination Date. The Parent agrees that it is jointly and severally liable for
all Reimbursement Obligations and other obligations with respect to Letters of
Credit previously issued or to be issued for the account or benefit of any
Subsidiary as if and to the same extent as if the Parent were the sole applicant
therefor, and that any Letters of Credit issued on application of a Subsidiary
or the joint application of the Parent and a Subsidiary shall be subject to all
the terms of this Agreement, including applicable sublimits.

         III.2.   REIMBURSEMENT.

                  (a The Borrowers hereby unconditionally agree to pay to the
Issuing Bank immediately on demand at the Principal Office all amounts required
to pay all drafts drawn or purporting to be drawn under the Letters of Credit
and all reasonable expenses incurred by the Issuing Bank in connection with the
Letters of Credit, and in any event and without demand to place in possession of
the Issuing Bank (which shall include Advances under the Revolving Credit
Facility if permitted by Section 2.1) sufficient funds to pay all debts and
liabilities arising under any Letter of Credit. The Issuing Bank agrees to give
the Borrowers prompt notice of any request for a draw under a Letter of Credit.
The Issuing Bank may charge any account the Borrowers may have with it for any
and all amounts the Issuing Bank pays under a Letter of Credit, plus charges and
reasonable expenses as from time to time agreed to by the Issuing Bank and the
Borrowers; provided that to the extent permitted by SECTION 2.1(C)(IV) , amounts
shall be paid pursuant to Advances under the Revolving Credit Facility. The
Borrowers agree to pay the Issuing Bank interest on any Reimbursement
Obligations not paid when due hereunder at the Base Rate, or the maximum rate
permitted by applicable law, if lower, such rate to be calculated on the basis
of a year of 360 days for actual days elapsed.

                                       29
<PAGE>

                  (b In accordance with the provisions of SECTION 2.1(C), the
Issuing Bank shall notify the Lender of any drawing under any Letter of Credit
promptly following the receipt by the Issuing Bank of such drawing.

                  (c The issuance by the Issuing Bank of each Letter of Credit
shall, in addition to the conditions precedent set forth in ARTICLE VI, be
subject to the conditions that such Letter of Credit be in such form and contain
such terms as shall be reasonably satisfactory to the Issuing Bank consistent
with the then current practices and procedures of the Issuing Bank with respect
to similar letters of credit, and the Borrowers shall have executed and
delivered such other instruments and agreements relating to such Letters of
Credit as the Issuing Bank shall have reasonably requested consistent with such
practices and procedures. All Letters of Credit shall be issued pursuant to and
subject to the Uniform Customs and Practice for Documentary Credits, 1993
revision, International Chamber of Commerce Publication No. 500 or, if the
Issuing Bank shall elect by express reference in an affected Letter of Credit,
the International Chamber of Commerce International Standby Practices commonly
referred to as "ISP98", or any subsequent amendments and revisions of either
thereof.

                  (d The Borrowers agree that the Issuing Bank may, in its sole
discretion, accept or pay, as complying with the terms of any Letter of Credit,
any drafts or other documents otherwise in order which may be signed or issued
by an administrator, executor, trustee in bankruptcy, debtor in possession,
assignee for the benefit of creditors, liquidator, receiver, attorney in fact or
other legal representative of a party who is authorized under such Letter of
Credit to draw or issue any drafts or other documents.

                  (e Without limiting the generality of the provisions of
SECTION 11.9, the Borrowers hereby agree to indemnify and hold harmless the
Issuing Bank from and against any and all claims and damages, losses,
liabilities, reasonable costs and expenses which the Issuing Bank may incur (or
which may be claimed against the Issuing Bank) by any Person by reason of or in
connection with the issuance or transfer of or payment or failure to pay under
any Letter of Credit; PROVIDED that the Borrowers shall not be required to
indemnify the Issuing Bank for any claims, damages, losses, liabilities, costs
or expenses to the extent, but only to the extent, (i) caused by the willful
misconduct or gross negligence of the party to be indemnified or (ii) caused by
the failure of the Issuing Bank to pay under any Letter of Credit after the
presentation to it of a request for payment strictly complying with the terms
and conditions of such Letter of Credit, unless such payment is prohibited by
any law, regulation, court order or decree. The indemnification and hold
harmless provisions of this SECTION 3.2(E) shall survive repayment of the
Obligations, occurrence of the Revolving Credit Termination Date and expiration
or termination of this Agreement.

                  (f Without limiting Borrowers' rights as set forth in SECTION
3.2(E), the obligation of the Borrowers to immediately reimburse the Issuing
Bank for drawings made under Letters of Credit and the Issuing Bank's right to
receive such payment shall be absolute, unconditional and irrevocable, and that
such obligations of the Borrowers shall be performed strictly in accordance with
the terms of this Agreement and such Letters of Credit and the related
Applications and Agreement for any Letter of Credit, under all circumstances
whatsoever, including the following circumstances:

                                       30
<PAGE>

                           (i) any lack of validity or enforceability of the
                  Letters of Credit, the obligation supported by the Letters of
                  Credit or any other agreement or instrument relating thereto
                  (collectively, the "Related LC Documents");

                           (ii) any amendment or waiver of or any consent to or
                  departure from all or any of the Related LC Documents;

                           (iii) the existence of any claim, setoff, defense
                  (other than the defense of payment in accordance with the
                  terms of this Agreement) or other rights which any Borrower
                  may have at any time against any beneficiary or any transferee
                  of a Letter of Credit (or any persons or entities for whom any
                  such beneficiary or any such transferee may be acting), the
                  Lender or any other Person, whether in connection with the
                  Loan Documents, the Related LC Documents or any unrelated
                  transaction;

                           (iv) any breach of contract or other dispute between
                  any Borrower and any beneficiary or any transferee of a Letter
                  of Credit (or any persons or entities for whom such
                  beneficiary or any such transferee may be acting), the Lender
                  or any other Person;

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

                           (vi) any delay, extension of time, renewal,
                  compromise or other indulgence or modification granted or
                  agreed to by the Lender, with or without notice to or approval
                  by the Borrowers in respect of any of Borrowers' Obligations
                  under this Agreement; or

                           (vii) any other circumstance or happening whatsoever,
                  whether or not similar to any of the foregoing.

Nothing contained in this subsection (f) shall relieve the Issuing Bank of its
obligations under the Uniform Customs and Practices for Documentary Credits,
1993 revision, International Chamber of Commerce Publication No. 500 or ISP98,
as the case may be.

         III.3. LETTER OF CREDIT FACILITY FEES. The Borrowers shall pay to the
Issuing Bank a fee on the aggregate amount available to be drawn on each
outstanding Letter of Credit at a rate equal to (a) the Applicable Margin for
each outstanding Standby Letter of Credit, and (b) .10% per annum for each
outstanding Documentary Letter of Credit. Such fees shall be due with respect to
each Letter of Credit quarterly in advance on the first day of each January,
April, July and October, the first such payment to be made (x) on the Closing
Date with respect to Letters of Credit outstanding and to the extent such fees
have not yet been paid for such Letters of Credit with respect to the then
current calendar quarter, or (y) on the date of issuance of a Letter of Credit,
and thereafter on the first day of the calendar quarter occurring after either
the Closing Date or the date of issuance of a Letter

                                       31

of Credit as applicable. The fees described in this SECTION 3.3 shall be

elapsed.

         III.4. ADMINISTRATIVE FEES. The Borrowers shall pay to the Issuing Bank
such administrative fee and other fees, if any, in connection with the Letters
of Credit in such amounts and at such times as the Issuing Bank and the

                             CHANGE IN CIRCUMSTANCES

         IV.1.    INCREASED COST AND REDUCED RETURN.

                  (a) If, after the date hereof, the adoption of any applicable
law, rule, or regulation, or any change in any applicable law, rule, or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender (or its
Lending Office) with any request or directive (whether or not having the force
of law) of any such governmental authority, central bank, or comparable agency:

                           (i) shall subject such Lender (or its Lending Office)
                  to any tax, duty, or other charge with respect to any
                  Eurodollar Rate Loans, its Note, or its obligation to make
                  Eurodollar Rate Loans, or change the basis of taxation of any
                  amounts payable to the Lender (or its Lending Office) under
                  this Agreement or its Note in respect of any Eurodollar Rate
                  Loans (other than taxes imposed on the overall net income of
                  the Lender by the jurisdiction in which the Lender has its
                  principal office or such Lending Office);

                           (ii) shall impose, modify, or deem applicable any
                  reserve, special deposit, assessment, or similar requirement
                  (other than the Reserve Requirement utilized in the
                  determination of the Eurodollar Rate) relating to any
                  extensions of credit or other assets of, or any deposits with
                  or other liabilities or commitments of, the Lender (or its
                  Lending Office), including the Revolving Credit Commitment of
                  the Lender hereunder; or

                           (iii) shall impose on the Lender (or its Lending
                  Office) or on the London interbank market any other condition
                  affecting this Agreement or its Note or any of such extensions
                  of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
(or its Lending Office) of making, Converting into, Continuing, or maintaining
any Eurodollar Rate Loans or to reduce any sum received or receivable by such
Lender (or its Lending Office) under this Agreement or its Note with respect to
any Eurodollar Rate Loans, then the Borrowers shall pay to the Lender on demand
such amount or amounts as will compensate the Lender for such increased cost or
reduction; PROVIDED that the Lender will not be entitled to any compensation for
any such increased cost or reduction if demand for payment thereof is made by
the Lender more than 180 days after the occurrence of the circumstances giving
rise to such claim. If the Lender requests compensation by the Borrowers under
this SECTION 4.1(A), the Borrowers may, by notice to the Lender, suspend the
obligation of the Lender to make or Continue Loans of the Type with respect to
which such compensation is requested, or to Convert Loans of any other Type into
Loans of such Type, until the event or condition giving rise to such request
ceases to be in effect (in which case the provisions of

                                       33
<PAGE>

SECTION 4.4 shall be applicable); PROVIDED that such suspension shall not affect
the right of the Lender to receive the compensation so requested.

         (b) If, after the date hereof, the Lender shall have determined that
the adoption of any applicable law, rule, or regulation regarding capital
adequacy or any change therein or in the interpretation or administration
thereof by any governmental authority, central bank, or comparable agency
charged with the interpretation or administration thereof, or any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such governmental authority, central bank, or comparable agency, has or
would have the effect of reducing the rate of return on the capital of the
Lender or any corporation controlling the Lender as a consequence of the
Lender's obligations hereunder to a level below that which the Lender or such
corporation could have achieved but for such adoption, change, request, or
directive (taking into consideration its policies with respect to capital
adequacy), then from time to time upon demand the Borrowers shall pay to the
Lender such additional amount or amounts as will compensate the Lender for such
reduction.

         (c) The Lender shall promptly notify the Borrowers of any event of
which it has knowledge, occurring after the date hereof, which will entitle the
Lender to compensation pursuant to this Section and will designate a different
Lending Office if such designation will avoid the need for, or reduce the amount
of, such compensation and will not, in the reasonable judgment of the Lender, be
otherwise disadvantageous to it. The Lender claiming compensation under this
Section shall furnish to the Borrowers a statement setting forth the additional
amount or amounts to be paid to it hereunder which shall be conclusive in the
absence of manifest error. In determining such amount, the Lender may use any
reasonable averaging and attribution methods that the Lender uses for its
customers that are similarly situated to the Borrowers.

         IV.2. LIMITATION ON TYPES OF LOANS. If on or prior to the first day of
any Interest Period for any Eurodollar Rate Loan:

                  (a) the Lender reasonably determines (which determination
         shall be conclusive) that by reason of circumstances affecting the
         relevant market, adequate and reasonable means do not exist for
         ascertaining the Eurodollar Rate for such Interest Period; or

                  (b) the Lender reasonably determines (which determination
         shall be conclusive) that the Eurodollar Rate will not adequately and
         fairly reflect the cost to the Lender of funding Eurodollar Rate Loans
         for such Interest Period;

then the Lender shall give the Borrowers prompt notice thereof specifying the
relevant Type of Loans and the relevant amounts or periods, and so long as such
condition remains in effect, the Lender shall be under no obligation to make
additional Loans of such Type, Continue Loans of such Type, or to Convert Loans
of any other Type into Loans of such Type and the Borrowers shall, on the last
day(s) of the then current Interest Period(s) for the outstanding Loans of the
affected Type, either prepay such Loans or Convert such Loans into another Type
of Loan in accordance with the terms of this Agreement.

                                       34
<PAGE>

         IV.3. ILLEGALITY. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for the Lender or its Lending
Office to make, maintain, or fund Eurodollar Rate Loans hereunder, then the
Lender shall promptly notify the Borrowers thereof and the Lender's obligation
to make or Continue Eurodollar Rate Loans and to Convert other Types of Loans
into Eurodollar Rate Loans shall be suspended until such time as the Lender may
again make, maintain, and fund Eurodollar Rate Loans (in which case the
provisions of SECTION 4.4 shall be applicable).

         IV.4. TREATMENT OF AFFECTED LOANS. If the obligation of the Lender to
make a Eurodollar Rate Loan or to Continue, or to Convert Loans of any other
Type into, Loans of a particular Type shall be suspended pursuant to SECTION 4.1
or 4.3 hereof (Loans of such Type being herein called "Affected Loans" and such
Type being herein called the "Affected Type"), the Lender's Affected Loans shall
be automatically Converted into Base Rate Loans on the last day(s) of the then
current Interest Period(s) for Affected Loans (or, in the case of a Conversion
required by SECTION 4.3 hereof, on such earlier date as the Lender may specify
to the Borrowers) and, unless and until the Lender gives notice as provided
below that the circumstances specified in SECTION 4.1 or 4.3 hereof that gave
rise to such Conversion no longer exist:

                  (a) to the extent that the Lender's Affected Loans have been
         so Converted, all payments and prepayments of principal that would
         otherwise be applied to the Lender's Affected Loans shall be applied
         instead to its Base Rate Loans; and

                  (b) all Loans that would otherwise be made or Continued by the
         Lender as Loans of the Affected Type shall be made or Continued instead
         as Base Rate Loans, and all Loans of the Lender that would otherwise be
         Converted into Loans of the Affected Type shall be Converted instead
         into (or shall remain as) Base Rate Loans.

         IV.5. COMPENSATION. Upon the request of the Lender, the Borrowers shall
pay to the Lender such amount or amounts as shall be sufficient (in the
reasonable opinion of the Lender) to compensate it for any loss, cost, or
expense (including loss of anticipated profits) incurred by it as a result of:

                  (a) any payment, prepayment, or Conversion of a Eurodollar
         Rate Loan for any reason (including, without limitation, the
         acceleration of the Loans pursuant to SECTION 10.1) on a date other
         than the last day of the Interest Period for such Loan; or

                  (b) any failure by the Borrowers for any reason (including,
         without limitation, the failure of any condition precedent specified in
         ARTICLE VI to be satisfied) to borrow, Convert, Continue, or prepay a
         Eurodollar Rate Loan on the date for such borrowing, Conversion,
         Continuation, or prepayment specified in the relevant notice of
         borrowing, prepayment, Continuation, or Conversion under this
         Agreement.

         IV.6. TAXES. (a) Any and all payments by the Borrowers to or for the
account of the Lender hereunder or under any other Loan Document shall be made
free and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, charges or

                                       35
<PAGE>

withholdings, and all liabilities with respect thereto, EXCLUDING, in the case
of the Lender, taxes imposed on its income, and franchise taxes imposed on it,
by the jurisdiction under the laws of which the Lender (or its Lending Office)
is organized or any political subdivision thereof (all such non-excluded taxes,
duties, levies, imposts, deductions, charges, withholdings, and liabilities
being hereinafter referred to as "Taxes"). If the Borrowers shall be required by
law to deduct any Taxes from or in respect of any sum payable under this
Agreement or any other Loan Document to the Lender, (i) the sum payable shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this SECTION 4.6) the
Lender receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrowers shall make such deductions, (iii) the
Borrowers shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law, and (iv) the Borrowers
shall furnish to the Lender, at its address referred to in SECTION 11.2, the
original or a certified copy of a receipt evidencing payment thereof.

         (b) In addition, the Borrowers agree to pay any and all present or
future stamp or documentary taxes and any other excise or property taxes or
charges or similar levies which arise from any payment made under this Agreement
or any other Loan Document or from the execution or delivery of, or otherwise
with respect to, this Agreement or any other Loan Document (hereinafter referred
to as "Other Taxes").

         (c) The Borrowers agree to indemnify the Lender for the full amount of
Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed or asserted by any jurisdiction on amounts payable under this SECTION
4.6) paid by the Lender and any liability (including penalties, interest, and
expenses) arising therefrom or with respect thereto.

         (d) If the Borrowers are required to pay additional amounts to or for
the account of the Lender pursuant to this SECTION 4.6, then the Lender will
agree to use reasonable efforts to change the jurisdiction of its Lending Office
so as to eliminate or reduce any such additional payment which may thereafter
accrue if such change, in the judgment of the Lender, is not otherwise
disadvantageous to the Lender.

         (e) Within thirty (30) days after the date of any payment of Taxes, the
Borrowers shall furnish to the Lender the original or a certified copy of a
receipt evidencing such payment.

         (f) Without prejudice to the survival of any other agreement of the
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in this SECTION 4.6 shall survive the termination of the Revolving Credit
Commitments and the payment in full of the Notes.

                                    SECURITY

         V.1. SECURITY. As security for the full and timely payment and
performance of all Obligations, the Borrowers shall, and shall cause all other
Credit Parties to, on or before the Closing Date, do or cause to be done all
things necessary in the opinion of the Lender and its counsel to grant to the
Lender a duly perfected first priority security interest in all Collateral
subject to no prior Lien or other encumbrance or restriction on transfer (other
than restrictions on transfer imposed by applicable securities laws). Without
limiting the foregoing, the Borrowers and each Subsidiary having rights in any
Subsidiary Securities shall on the Closing Date deliver to the Lender, in form
and substance reasonably acceptable to the Lender, (A) a Pledge Agreement which
shall pledge to the Lenders 65% of the Voting Stock of each Direct Foreign
Subsidiary, (B) if such Subsidiary Securities are in the form of certificated
securities, such certificated securities, together with undated stock powers or
other appropriate transfer documents endorsed in blank pertaining thereto, and
(C) if such Subsidiary Securities do not constitute certificated securities, the
Borrowers shall take such further action and deliver or cause to be delivered
such further documents as required to effect the transactions contemplated by
this ARTICLE V. The Parent shall, and shall cause each Subsidiary, to pledge to
the Lender for the benefit of the Lender (and as appropriate to reaffirm its
prior pledge of) all of the Pledge Interests of any Direct Foreign Subsidiary
which is a Material Subsidiary acquired or created after the Closing Date and to
deliver to the Lender all of the documents and instruments in connection
therewith as are required pursuant to the terms of SECTION 8.19 and of the
Pledge Agreement.

         V.2. FURTHER ASSURANCES. At the request of the Lender, the Borrowers
will or will cause all other Credit Parties, as the case may be to execute, by
its duly authorized officers, alone or with the Lender, any certificate,
instrument, financing statement, control agreement, statement or document, or to
procure any such certificate, instrument, statement or document, or to take such
other action (and pay all connected costs) which the Lender reasonably deems
necessary from time to time to create, continue or preserve the liens and
security interests in Collateral (and the perfection and priority thereof) of
the Lender contemplated hereby and by the other Loan Documents and specifically
including all Collateral acquired by the Borrowers or other Credit Party after
the Closing Date. The Lender is hereby irrevocably authorized to execute and
file or cause to be filed, with or if permitted by applicable law without the
signature of the Borrowers or any Credit Party appearing thereon, all Uniform
Commercial Code financing statements reflecting the Borrowers or any other
Credit Party as "debtor" and the Lender as "secured party", and continuations
thereof and amendments thereto, as the Lender reasonably deems necessary or
advisable to give effect to the transactions contemplated hereby and by the
other Loan Documents.

                         REPRESENTATIONS AND WARRANTIES

         Each Borrower represents and warrants with respect to itself and to its
Subsidiaries (which representations and warranties shall survive the delivery of
the documents mentioned herein and the making of Loans), that:

         VII.1.   ORGANIZATION AND AUTHORITY.

                  (a) The Borrower and each Subsidiary is a corporation or

         power and authority to own its properties and assets and to carry on
         its business as now being conducted and as contemplated in the Loan
         Documents, and (y) is qualified to do business in every jurisdiction in
         which failure so to qualify would have a Material Adverse Effect;

                  (c) The Borrower has the power and authority to execute,

         hereunder, and to execute, deliver and perform each of the other Loan

         embargo or act of God; and

                  (c) except as set forth in the financial statements referred
         to in SECTION 7.6(A) or in SCHEDULE 7.6 or permitted by SECTION 9.5,

the extent that such taxes have become due.

         VII.9.   OTHER AGREEMENTS.  Neither the Borrower nor any Subsidiary is

                  (a) a party to or subject to any judgment, order, decree,

         individually or in the aggregate could reasonably be expected to have a

any governmental instrumentality or agency or arbitral body pending, or, to the
knowledge of the Borrower, threatened by or against the Borrower or any

         VII.11. MARGIN STOCK. The proceeds of the borrowings made hereunder
will be used by the Borrower only for the purposes expressly authorized herein.
None of such proceeds will be used, directly or indirectly, for the purpose of

margin stock or for any other purpose which might constitute any of the Loans
under this Agreement a "purpose credit" within the meaning of said Regulation U
or Regulation X (12 C.F.R. Part 224) of the Board. Neither the Borrower nor any
agent acting in its behalf has taken or will take any action which might cause
this Agreement or any of the documents or instruments delivered pursuant hereto

of 1934, as amended, or the Securities Act of 1933, as amended, or any state
securities laws, in each case as in effect on the date hereof.

"promoter" or "principal underwriter" for, an "investment company", as such
terms are defined in the Investment Company Act of 1940, as amended (15 U.S.C.
ss. 80a-1, et seq.). The application of the proceeds of the Loans and repayment
thereof by the Borrowers and the performance by the Borrower and its
Subsidiaries of the transactions contemplated by the Loan Documents will not
violate any provision of said Act, or any rule, regulation or order issued by
the Securities and Exchange Commission thereunder, in each case as in effect on
the date hereof.

         VII.13. PATENTS, ETC. The Borrower and each of its Subsidiaries owns or
has the right to use, under valid license agreements or otherwise, all material
patents, licenses, franchises, trademarks, trademark rights, trade names, trade

its businesses as now conducted and as contemplated by the Loan Documents,
without known conflict with any patent, license, franchise, trademark, trade
secret, trade name, copyright, other proprietary right of any other Person.

Loan Document or certificate or document executed and delivered by or on behalf
of the Borrower or any Subsidiary in accordance with or pursuant to any Loan

                                       44
<PAGE>

Documents contains any misrepresentation or untrue statement of material fact or
omits to state a material fact necessary, in light of the circumstance under
which it was made, in order to make any such warranty, representation or
statement contained therein not misleading.

         VII.15. NO CONSENTS, ETC. Neither the respective businesses or
properties of the Borrower or any Subsidiary, nor any relationship between the
Borrower or any Subsidiary and any other Person, nor any circumstance in
connection with the execution, delivery and performance of the Loan Documents
and the transactions contemplated thereby, is such as to require a consent,
approval or authorization of, or filing, registration or qualification with, any
Governmental Authority or any other Person on the part of the Borrower or any
Subsidiary as a condition to the execution, delivery and performance of, or
consummation of the transactions contemplated by the Loan Documents, which, if
not obtained or effected, would be reasonably likely to have a Material Adverse
Effect, or if so, such consent, approval, authorization, filing, registration or
qualification has been duly obtained or effected, as the case may be.

         VII.16.  EMPLOYEE BENEFIT PLANS.

                  (a) The Parent and each ERISA Affiliate is in compliance with

         Plan that is intended to be qualified under Section 401(a) of the Code
         has been determined by the Internal Revenue Service to be so qualified,
         and each trust related to such plan has been determined to be exempt
         under Section 501(a) of the Code. No material liability has been
         incurred by the Borrowers or any ERISA Affiliate which remains
         unsatisfied for any taxes or penalties with respect to any Employee
         Benefit Plan or any Multiemployer Plan;

         in a nonexempt prohibited transaction described in Section 4975 of the
         Code or Section 406 of ERISA affecting any of the Employee Benefit
         Plans or the trusts created thereunder which could subject any such
         Employee Benefit Plan or trust to a material tax or penalty on
         prohibited transactions imposed under Internal Revenue Code Section
         4975 or ERISA, (ii) incurred any accumulated funding deficiency with
         respect to any Employee Benefit Plan, whether or not waived, or any
         other liability to the PBGC which remains outstanding other than the
         payment of premiums and there are no premium payments which are due and
         unpaid, (iii) failed to make a required contribution or payment to a
         Multiemployer Plan, or (iv) failed to make a required installment or
         other required payment under Section 412 of the Code, Section 302 of
         ERISA or the terms of such Employee Benefit Plan;

                  (c) No Termination Event has occurred or is reasonably
         expected to occur with respect to any Pension Plan or Multiemployer
         Plan, and neither the Parent nor any ERISA Affiliate has incurred any
         unpaid withdrawal liability with respect to any Multiemployer Plan;

                                       45
<PAGE>

                  (d) The present value of all vested accrued benefits under
         each Employee Benefit Plan which is subject to Title IV of ERISA, did
         not, as of the most recent valuation date for each such plan, exceed
         the then current value of the assets of such Employee Benefit Plan
         allocable to such benefits;

                  (e) To the best of the Borrower's knowledge, each Employee
         Benefit Plan subject to Title IV of ERISA, maintained by the Parent or
         any ERISA Affiliate, has been administered in accordance with its terms
         in all material respects and is in compliance in all material respects
         with all applicable requirements of ERISA and other applicable laws,
         regulations and rules;

                  (f) The consummation of the Loans and the issuance of the
         Letters of Credit provided for herein will not involve any prohibited
         transaction under ERISA which is not subject to a statutory or
         administrative exemption; and

                  (g) No material proceeding, claim, lawsuit and/or
         investigation exists or, to the best knowledge of the Borrower after
         due inquiry, is threatened concerning or involving any Employee Benefit
         Plan.

         VII.17. NO DEFAULT. As of the date hereof, there does not exist any
Default or Event of Default hereunder.

         VII.18. HAZARDOUS MATERIALS. Except as set forth on SCHEDULE 7.18, the
Borrower and each Subsidiary is in compliance with all applicable Environmental
Laws in all material respects. Neither the Borrower nor any Subsidiary has been
notified of any action, suit, proceeding or investigation which, and neither the
Borrower nor any Subsidiary is aware of any facts which, (i) calls into
question, or could reasonably be expected to call into question, compliance by
the Borrower or any Subsidiary with any Environmental Laws, (ii) which seeks, or
could reasonably be expected to form the basis of a meritorious proceeding, to
suspend, revoke or terminate any license, permit or approval necessary for the
generation, handling, storage, treatment or disposal of any Hazardous Material,

meritorious proceeding to cause, any property of the Borrower or any Subsidiary
to be subject to any restrictions on ownership, use, occupancy or
transferability under any Environmental Law.

         VII.19. RICO. Neither the Borrower nor any Subsidiary is engaged in or
has engaged in any course of conduct that could subject any of their respective
properties to any Lien, seizure or other forfeiture under any criminal law,
racketeer influenced and corrupt organizations law, civil or criminal, or other
similar laws.

         VII.20. YEAR 2000 COMPLIANCE. The Borrower and its Subsidiaries have
(i) initiated a review and assessment of all areas within its and each of their
Subsidiaries' business and operations (including those affected by information
received from suppliers and vendors) that could reasonably be expected to be
adversely affected by the Year 2000 Problem, (ii) developed a plan and timeline
for addressing the Year 2000 Problem by not later than September 30, 1999, and
(iii) to date, implemented that plan substantially in accordance with that

<PAGE>

Borrower reasonably believes that all computer applications (including those
affected by information received from its suppliers and vendors) that are
material to its or any of its Subsidiaries' business and operations will on a
timely basis be Year 2000 Compliant, except to the extent that a failure to do
so could not reasonably be expected to have Material Adverse Effect.

                           (a) either or both of the following actions may be
                  taken: (i) the Lender may declare any obligation of the Lender
                  and the Issuing Bank to make further Loans or to issue
                  additional Letters of Credit terminated, whereupon the
                  obligation of the Lender to make further Loans and of the
                  Issuing Bank to issue additional Letters of Credit, hereunder
                  shall terminate immediately, and (ii) the Lender, at its
                  option, declare by notice to the Borrowers any or all of the
                  Obligations to be immediately due and payable, and the same,
                  including all interest accrued thereon and all other
                  obligations of the Borrowers to the Lender, shall forthwith
                  become immediately due and payable without presentment,
                  demand, protest, notice or other formality of any kind, all of
                  which are hereby expressly waived, anything contained herein
                  or in any instrument evidencing the Obligations to the
                  contrary notwithstanding; PROVIDED, however, that
                  notwithstanding the above, if there shall occur an Event of
                  Default under clause (g) or (h) above, then the obligation of
                  the Lender to make Loans and of the Issuing Bank to issue
                  Letters of Credit hereunder shall automatically terminate and
                  any and all of the Obligations shall be immediately due and
                  payable without the necessity of any action by the Lender or
                  notice to the Lender;

                           (b) the Borrowers shall, upon demand of the Lender,
                  deposit cash with the Issuing Bank in an amount equal to the
                  amount of any Letter of Credit Outstandings, as collateral
                  security for the repayment of any future drawings or payments
                  under such Letters of Credit, and such amounts shall be held
                  by the Issuing Bank pursuant to the terms of the LC Account
                  Agreement; and

                           (c) the Lender shall have all of the rights and
                  remedies available under the Loan Documents or under any
                  applicable law.

         X.2. LENDER TO ACT. In case any one or more Events of Default shall
occur and not have been waived, the Lender may proceed to protect and enforce
its rights or remedies either by suit in equity or by action at law, or both,
whether for the specific performance of any covenant, agreement

                                       63
<PAGE>

or other provision contained herein or in any other Loan Document, or to enforce
the payment of the Obligations or any other legal or equitable right or remedy.

         X.3. CUMULATIVE RIGHTS. No right or remedy herein conferred upon the
Lender is intended to be exclusive of any other rights or remedies contained
herein or in any other Loan Document, and every such right or remedy shall be
cumulative and shall be in addition to every other such right or remedy
contained herein and therein or now or hereafter existing at law or in equity or
by statute, or otherwise.

         X.4. NO WAIVER. No course of dealing between the Borrowers and the
Lender or any failure or delay on the part of the Lender in exercising any
rights or remedies under any Loan Document or otherwise available to it shall
operate as a waiver of any rights or remedies and no single or partial exercise
of any rights or remedies shall operate as a waiver or preclude the exercise of
any other rights or remedies hereunder or of the same right or remedy on a
future occasion.

         X.5. ALLOCATION OF PROCEEDS. If an Event of Default has occurred and
not been waived, and the maturity of the Note has been accelerated pursuant to
ARTICLE X hereof, all payments received by the Lender hereunder, in respect of
any principal of or interest on the Obligations or any other amounts payable by
the Borrowers hereunder, shall be applied by the Lender in the following order:

         Documents, if any;

                  (g) amounts due to any of the Lender in respect of Obligations
         consisting of liabilities under any Swap Agreement with the Lender; and

Default the Lender may set off the obligations and liabilities of Borrowers
against any and all monies then owed by the Lender to the Borrowers in any
capacity whatsoever whether or not then due and the Lender shall be deemed to

shall then be effective only for the period and on the conditions and for the
specific instances and purposes specified in such writing. No notice to or
demand on the Borrowers in any case shall entitle the Borrowers to any other or
further notice or demand in similar or other circumstances, except as otherwise
expressly provided herein. No delay or omission on the Lender's part in

         XI.8. TERMINATION. The termination of this Agreement shall not affect
any rights of the Borrowers or the Lender or any obligation of the Borrowers or
the Lender, arising prior to the effective date of such termination, and the
provisions hereof shall continue to be fully operative until all transactions
entered into or rights created or obligations incurred prior to such termination
have been fully disposed of, concluded or liquidated and the Obligations arising
prior to or after such termination have been irrevocably paid in full. The
rights granted to the Lender under the Loan Documents shall continue in full
force and effect, notwithstanding the termination of this Agreement, until all
of the Obligations have been paid in full after the termination hereof (other
than Obligations in the nature of continuing indemnities or expense
reimbursement obligations not yet due and payable, which shall continue) or the
Borrowers have furnished the Lender with an indemnification satisfactory to the
Lender with respect thereto. All representations, warranties, covenants, waivers
and agreements contained herein shall survive termination hereof until payment
in full of the Obligations unless otherwise provided herein. Notwithstanding the
foregoing, if after receipt of any payment of all or any part of the
Obligations, the Lender is for any reason compelled to surrender such payment to
any Person because such payment is determined to be void or voidable as a
preference, impermissible setoff, a diversion of trust funds or for any other
reason, this Agreement shall continue in full force and the Borrowers shall be
liable to, and shall indemnify and hold the Lender harmless for, the amount of
such payment surrendered until the Lender shall have been finally and
irrevocably paid in full. The provisions of the foregoing sentence shall be and
remain effective notwithstanding any contrary action which may have been taken
by the Lender in reliance upon such payment, and any such contrary action so
taken shall be without prejudice to the Lender's rights under this Agreement and
shall be deemed to have been conditioned upon such payment having become final
and irrevocable.

         XI.9. INDEMNIFICATION; LIMITATION OF LIABILITY. In consideration of the
execution and delivery of this Agreement by the Lender and the extension of
credit under the Loans, the Borrowers hereby indemnifies, exonerates and holds
the Lender and its affiliates, officers, directors, employees, agents and
advisors (collectively, the "Indemnified Parties") free and harmless from and
against any and all claims, actions, causes of action, suits, losses, costs,
liabilities and damages, and expenses incurred in connection therewith
(irrespective of whether any such Indemnified Party is a party to the action for
which indemnification hereunder is sought), including reasonable attorneys' fees
and disbursements (collectively, the "Indemnified Liabilities") that may be
incurred by or asserted or awarded against any Indemnified Party, in each case
arising out of or in connection with or by reason of, or in connection with the
execution, delivery, enforcement, performance or administration of this
Agreement and the other Loan Documents, or any transaction financed or to be
financed in whole or in part, directly or indirectly, with the proceeds of any
Loan or Letter of Credit, whether or not such action is brought against the
Lender, the shareholders or creditors of the Lender or an Indemnified Party or
an Indemnified Party is otherwise a party thereto and whether or not the
transactions contemplated herein are consummated, except to the extent such
claim, damage, loss, liability or expense is found in a final, non-appealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct, and if and to the
extent that the foregoing undertaking may be unenforceable for any reason, the
Borrowers hereby agree to make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under
applicable law. The Borrowers agree that no Indemnified Party shall have any
liability (whether direct or indirect, in contract or tort or otherwise) to it,
any of its Subsidiaries, any Credit Party, or any security holders or creditors
thereof arising out of, related to or in connection with the transactions
contemplated herein, except to the extent that such liability is found in a
final non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party's gross negligence or willful misconduct;
provided, however, in no event shall any Indemnified Party be liable for
consequential, indirect or special, as opposed to direct, damages.

         XI.10. SEVERABILITY. If any provision of this Agreement or the other
Loan Documents shall be determined to be illegal or invalid as to one or more of
the parties hereto, then such provision shall remain in effect with respect to
all parties, if any, as to whom such provision is neither illegal nor invalid,
and in any event all other provisions hereof shall remain effective and binding
on the parties hereto.

         XI.11. ENTIRE AGREEMENT. This Agreement, together with the other Loan
Documents, constitutes the entire agreement among the parties with respect to
the subject matter hereof and supersedes all previous proposals, negotiations,
representations, commitments and other communications between or among the
parties, both oral and written, with respect thereto.

         XI.12. AGREEMENT CONTROLS. In the event that any term of any of the
Loan Documents other than this Agreement conflicts with any express term of this
Agreement, the terms and provisions of this Agreement shall control to the
extent of such conflict.

         XI.13. USURY SAVINGS CLAUSE. Notwithstanding any other provision
herein, the aggregate interest rate charged under any of the Notes, including
all charges or fees in connection therewith

                                       68
<PAGE>

deemed in the nature of interest under applicable law shall not exceed the
Highest Lawful Rate (as such term is defined below). If the rate of interest
(determined without regard to the preceding sentence) under this Agreement at
any time exceeds the Highest Lawful Rate (as defined below), the outstanding
amount of the Loans made hereunder shall bear interest at the Highest Lawful
Rate until the total amount of interest due hereunder equals the amount of
interest which would have been due hereunder if the stated rates of interest set
forth in this Agreement had at all times been in effect. In addition, if when
the Loans made hereunder are repaid in full the total interest due hereunder
(taking into account the increase provided for above) is less than the total
amount of interest which would have been due hereunder if the stated rates of
interest set forth in this Agreement had at all times been in effect, then to
the extent permitted by law, the Borrowers shall pay to the Lender an amount
equal to the difference between the amount of interest paid and the amount of
interest which would have been paid if the Highest Lawful Rate had at all times
been in effect. Notwithstanding the foregoing, it is the intention of the Lender
and the Borrowers to conform strictly to any applicable usury laws. Accordingly,
if the Lender contracts for, charges, or receives any consideration which
constitutes interest in excess of the Highest Lawful Rate, then any such excess
shall be cancelled automatically and, if previously paid, shall at the Lender's
option be applied to the outstanding amount of the Loans made hereunder or be
refunded to the Borrowers. As used in this paragraph, the term "Highest Lawful
Rate" means the maximum lawful interest rate, if any, that at any time or from
time to time may be contracted for, charged, or received under the laws
applicable to the Lender which are presently in effect or, to the extent allowed
by law, under such applicable laws which may hereafter be in effect and which
allow a higher maximum nonusurious interest rate than applicable laws now allow.

         XI.14.   GOVERNING LAW; WAIVER OF JURY TRIAL.

                  (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN
         THOSE SECURITY INSTRUMENTS WHICH EXPRESSLY PROVIDE THAT THEY SHALL BE

         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF FLORIDA

         OF JURISDICTION OVER ANY OF THEM AND THEIR PROPERTY BY, ANY SUCH COURT

         IRREVOCABLY SUBMIT GENERALLY AND

         UNCONDITIONALLY TO THE JURISDICTION OF ANY SUCH COURT IN ANY SUCH SUIT,
         ACTION OR PROCEEDING.

                  (c) THE BORROWERS AGREE THAT SERVICE OF PROCESS MAY BE MADE BY
         PERSONAL SERVICE OF A COPY OF THE SUMMONS AND COMPLAINT OR OTHER LEGAL
         PROCESS IN ANY SUCH SUIT, ACTION OR PROCEEDING, OR BY REGISTERED OR
         CERTIFIED MAIL (POSTAGE PREPAID) TO THE ADDRESS OF THE BORROWERS
         PROVIDED IN SECTION 11.2, OR BY ANY OTHER METHOD OF SERVICE PROVIDED
         FOR UNDER THE APPLICABLE LAWS IN EFFECT IN THE STATE OF FLORIDA.

                  (d) NOTHING CONTAINED IN SUBSECTIONS (A) OR (B) HEREOF SHALL
         PRECLUDE THE LENDER FROM BRINGING ANY SUIT, ACTION OR PROCEEDING
         ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT IN THE COURTS OF ANY
         JURISDICTION WHERE THE BORROWERS OR ANY OF THE BORROWERS' PROPERTY OR
         ASSETS MAY BE FOUND OR LOCATED. TO THE EXTENT PERMITTED BY THE
         APPLICABLE LAWS OF ANY SUCH JURISDICTION, THE BORROWERS HEREBY
         IRREVOCABLY SUBMIT TO THE JURISDICTION OF ANY SUCH COURT AND EXPRESSLY
         WAIVE, IN RESPECT OF ANY SUCH SUIT, ACTION OR PROCEEDING, OBJECTION TO
         THE EXERCISE OF JURISDICTION OVER THEM AND THEIR PROPERTY BY ANY SUCH
         OTHER COURT OR COURTS WHICH NOW OR HEREAFTER MAY BE AVAILABLE UNDER
         APPLICABLE LAW.

                  (e) IN ANY ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY
         RIGHTS OR REMEDIES UNDER OR RELATED TO ANY LOAN DOCUMENT OR ANY
         AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR THAT MAY IN
         THE FUTURE BE DELIVERED IN CONNECTION THEREWITH, THE BORROWERS AND THE
         LENDER HEREBY AGREE, TO THE EXTENT PERMITTED BY APPLICABLE LAW, THAT
         ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT
         BEFORE A JURY AND HEREBY IRREVOCABLY WAIVE, TO THE EXTENT PERMITTED BY
         APPLICABLE LAW, ANY RIGHT SUCH PERSON MAY HAVE TO TRIAL BY JURY IN ANY
         SUCH ACTION OR PROCEEDING.

acquired or created after the date thereof, and

         WHEREAS, the Guarantors will substantially benefit from the loans and
advances made or to be made by the Lender and the letters of credit issued or to
be issued by the Issuing Bank to the Borrower under the Credit Agreement;

         NOW, THEREFORE, in consideration of the premises and conditions herein
set forth, it is hereby agreed as follows:

         1. Guarantors hereby absolutely and unconditionally guaranty, jointly
and severally, to the Lender, with full power to satisfy, discharge, release,
foreclose, assign and transfer the within Guaranty, the due performance and full
and prompt payment, whether at maturity or by acceleration or otherwise, of any
and all Borrower's Liabilities (as hereinafter defined) (hereinafter
collectively referred to as the "Guarantors' Obligations"); PROVIDED, HOWEVER,
that the liability of any Guarantor hereunder with respect to the Guarantors'
Obligations shall be limited to an aggregate amount equal to the largest amount
that would not render its obligations hereunder subject to avoidance under
Section 548 of the United States Bankruptcy Code or any comparable provisions of
any applicable state law.

         2. For purposes of this Guaranty, "Borrower's Liabilities" shall mean
and include any and all advances (including those made by the Lender to protect,
enlarge or preserve the priority, propriety, or amount of any lien in favor of
the Lender against mechanic's lien, equitable lien, or statutory claimants, or
otherwise), debts, obligations and liabilities of Borrower pursuant to the terms

                                      G-1
<PAGE>

of the Credit Agreement, the Notes, any Swap Agreement and all other Loan
Documents executed in connection therewith heretofore, now, or hereafter made,
incurred or created, extended, renewed, replaced, refinanced or restructured,
whether or not from time to time decreased or extinguished and later increased,
created or incurred, whether voluntary or involuntary and, however arising,
whether due or not, absolute or contingent, liquidated or non-liquidated,
determined or undetermined, and whether Borrower may be liable individually or
jointly with others, or whether recovery upon such indebtedness may be or
hereafter become barred by any statute of limitations, or whether such
indebtedness may be or hereafter become otherwise unenforceable (collectively
referred to hereinafter as the "Borrower's Liabilities"). This is a continuing
Guaranty relating to the Borrower's Liabilities, and any other indebtedness
arising under subsequent or successive transactions which increase the
Borrower's Liabilities, and said Guaranty shall be irrevocable and remain
outstanding until all the Borrower's Liabilities are satisfied in full and the
Lender shall have no further obligation to make Loans and Advances and the
Issuing Bank to issue Letters of Credit under the Credit Agreement.

         3. The obligations of the Guarantors hereunder are independent of the
obligations of Borrower, and a separate action or actions may be brought and
prosecuted against any Guarantor, whether such action is brought against
Borrower or whether Borrower be joined in any such action or actions.

         4. Each Guarantor authorizes the Lender, without notice or demand and
without affecting such Guarantor's liability hereunder, from time to time to (a)
renew, amend, compromise, extend, accelerate or otherwise change the time for
payment of, or otherwise change the terms of the Borrower's Liabilities or any
part thereof, including increase or decrease of the rate of interest thereon;
(b) take and hold security for the payment of this Guaranty and the Guarantors'
Obligations and exchange, enforce, waive and release any such security; (c)
apply such security and direct the order or manner of sale thereof as the Lender
may determine; and (d) release or substitute any one or more endorsers or
guarantors of the Borrower's Liabilities. The Lender may without notice assign
this Guaranty in whole or in part in connection with an assignment as permitted
under the Credit Agreement.

         5. Each Guarantor waives any right to require the Lender to (a) proceed
against Borrower; (b) proceed against or exhaust any security held from
Borrower; or (c) pursue any other remedy in the Lender's power whatsoever. Each
Guarantor waives any defense arising by reason of any disability or other
defense of Borrower or by reason of the cessation from any cause whatsoever of
the liability of the Borrower to the Lender. Until all the Borrower's
Liabilities shall have been paid in full and the Lender shall have no further
obligation to make Loans and Advances and the Issuing Bank to issue Letters of
Credit under the Credit Agreement, each Guarantor waives any right to endorse
any remedy which the Lender now has or may hereafter have against the Borrower,
and waives any benefit of, and any right to participate in, any security now or
hereafter held by the Lender as collateral security for the Borrower's
Liabilities. Each Guarantor waives all presentments, demands for performance,
notices of non-performance, protests, notices of dishonor, notices of acceptance
of this Guaranty and of the existence, creation, or incurring of new or
additional indebtedness; any defense or circumstance which might otherwise
constitute a legal or

                                      G-2
<PAGE>

equitable discharge of a guarantor or a surety; and all rights under any state
or federal statute dealing with or affecting the rights of creditors. Each
Guarantor covenants to cause Borrower to maintain and preserve the
enforceability of any instruments now or hereafter executed in favor of the
Lender, and to take no action of any kind which might be the basis for a claim
that such Guarantor has any defense hereunder in connection with the
above-mentioned Loan Documents, other than payment in full of the Borrower's
Liabilities. Each Guarantor waives any right or claim of right to cause a
marshaling of Borrower's assets or to require the Lender to proceed against the
Guarantors or any other guarantor of the Borrower's Liabilities in any
particular order. No delay on the part of the Lender in the exercise of any
right, power or privilege under the Loan Documents or under this Guaranty shall
operate as a waiver of any such privilege, power or right.

         6. Until the Borrower's Liabilities are paid in full and the Lender is
under no further obligation to make Loans and Advances and the Issuing Bank to
issue Letters of Credit under the Credit Agreement, any indebtedness of Borrower
now or hereafter held by any Guarantor is hereby subordinated to the Borrower's
Liabilities; and such indebtedness of Borrower to any Guarantor, if the Lender
so requests, shall be collected, enforced and received by such Guarantor as
trustee for the Lender and be paid over to the Lender on account of the
Borrower's Liabilities, but without reducing or affecting in any manner the
liability of such Guarantor under the other provisions of this Guaranty. Each
Guarantor, at the request of the Lender, shall execute such further documents in
favor of the Lender to further evidence and support the purpose of this Section
6. Each Guarantor hereby irrevocably waives and releases any right or rights of
subrogation or contribution existing at law, by contract or otherwise to recover
all or a portion of any payment made hereunder from the Borrower or any other
guarantor.

         7. Upon the default of Borrower with respect to any of its obligations
or liabilities to the Lender in connection with the Loan Documents, or in case
Borrower or any Guarantor shall become insolvent or make an assignment for the
benefit of creditors, or if a petition in bankruptcy or for corporate
reorganization or for an arrangement be filed by or against Borrower or any
Guarantor (and if such petition is filed against Borrower or any Guarantor and
is not stayed or dismissed within sixty (60) days), or in the event of the
appointment of a receiver for Borrower or any Guarantor of their properties, or
in the event a judgment is obtained or warrant of attachment is issued against
Borrower or any Guarantor (which judgment or warrant is not satisfied or bonded
or removed within sixty (60) days), all or any part of the Guarantors'
Obligations shall, without notice or demand, at the option of the Lender, become
immediately due and payable and shall be paid forthwith, jointly and severally,
by Guarantors without any offset of any kind whatsoever, without the Lender
first being required to make demand upon the Borrower or pursue any of its
rights against Borrower, or against any other person, including other guarantors
(whether or not party to this Guaranty).

         8. Notwithstanding any provision herein or in any instrument now or
hereafter executed in connection with this Guaranty or the Guarantors'
Obligations hereunder, the total liability for payments in the nature of
interest shall not exceed the limits now imposed by the usury laws of the State
of Florida governing the provisions of this Guaranty or in any instrument now or
hereafter executed in connection with this Guaranty or the Guarantors'
Obligations hereunder.

                                      G-3
<PAGE>

         9. Each Guarantor acknowledges that the Lender has been induced by this
Guaranty to make and to continue to make Loans and Advances to the Borrower and
the Issuing Bank to issue and continue to issue Letters of Credit on behalf of
the Borrower and its Subsidiaries under the Credit Agreement, and this Guaranty
shall, without further reference or assignment, pass to, and may be relied upon
and enforced by, any successor or participant or assignee of the Lender in and
to any of Borrower's Liabilities.

         10. Each Guarantor hereby warrants and represents to the Lender, that:
(a) it is a duly organized and validly existing corporation under the laws of
the state of its incorporation; (b) it is qualified to do business in each state
in which qualification is necessary; (c) it has the power to execute this
Guaranty; (d) that the execution of this Guaranty has been duly authorized; and
(e) that this Guaranty is a binding and valid corporate obligation.

         11. Each Guarantor acknowledges that the liabilities of said Guarantor
shall be independent of the Obligations of Borrower, and separate or joint
actions may be instituted by the Lender, against such Guarantors; and said
actions may be instituted against Borrower and any of the Guarantors, or
separately against any of the Guarantors. Any action taken by the Lender
pursuant to the provisions herein contained or contained in the Credit
Agreement, the Notes or the Loan Documents, shall not release the party to this
Guaranty until all of the Borrower's Liabilities are paid in full and the Lender
shall have no further obligation to make Loans and Advances and the Issuing Bank
to issue Letters of Credit under the Credit Agreement.

         12. The Guarantors will upon demand pay to the Lender, jointly and
severally, the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
it may reasonably incur in connection with enforcement of this Guaranty or the
failure by any Guarantor to perform or observe any of the provisions hereof. The
Guarantors agree to indemnify and hold harmless the Lender from and against any
and all claims, demands, losses, judgments and liabilities (including
liabilities for penalties) of whatsoever kind or nature, growing out of or
resulting from this Guaranty or the exercise by the Lender of any right or
remedy granted to it hereunder or under the other Loan Documents, other than
such items arising out of the bad faith, gross negligence or willful misconduct
on the part of the Lender. If and to the extent that the obligations of the
Guarantors under this Section 12 are unenforceable for any reason, Guarantors
hereby agree to make the maximum contribution to the payment and satisfaction of
such obligations which is permissible under applicable law.

         13. If claim is ever made upon the Lender for repayment or recovery of
any amount or amounts received in payment or on account of the Guarantors'
Obligations and the Lender repays all or part of said amount by reason of (a)
any judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property, or (b) any settlement or
compromise of any such claim effected by the Lender with any such claimant
(including the original obligor), then and in such event each Guarantor agrees
that any such judgment, decree, order, settlement or compromise shall be binding
upon it, notwithstanding any revocation hereof or the cancellation of any Notes
or other instrument evidencing any Guarantied Obligations or any security
therefor, and the Guarantors shall be and remain jointly and severally liable to
the Lender

                                      G-4
<PAGE>

for the amount so repaid or recovered to the same extent as if such amount had
never originally been received by the Lender.

         14. All notices required to be given hereunder shall be in writing, and
shall be given by certified mail, return receipt requested, and shall be deemed
given when they shall have been deposited in the United States Mail, with
sufficient postage prepaid thereon to carry them to their addressed destination,
addressed to the party for whom it is intended, as follows:

ANY OTHER LOAN DOCUMENT.
