     WHEREAS, the Company desires that Employee continue to provide services to
the Company and Employee desires to continue to render services to the Company;
and

     WHEREAS, the parties desire to further the goals of stability and security,

     NOW, THEREFORE, in consideration of these premises and other good and
valuable consideration, the Company and Employee hereby agree as follows:

     1.   Employment. The Company agrees to employ Employee, and Employee agrees
to be so employed, in the capacity of President of Micron Products Inc. The term
of the employment shall commence as of October 5th, 2001 and terminate on

Agreement.

     2.   Duties. Employee shall at all times discharge his duties in
consultation with and under the supervision of the Company's Board of Directors.
The parties have acknowledged that the Company is in a period of transition and
that the duties of the Employee may change from time to time.

     3.   Time and Efforts. Employee shall conscientiously devote all of his
time and attention and best efforts during working hours in the discharging of
his duties. It is understood and agreed that Employee's present duties generally
require forty (40) hours during each working week and that, on occasion,

     4.   Compensation.

payments shall be subject to withholding and other applicable taxes. Employee
shall be entitled to an annual review for raises in accordance with then-current
Company policy.

     (b)  Bonus Compensation and Other Benefits. In addition to his base
compensation set forth in Paragraph 4(a) above, Employee shall be entitled to
participate in such bonus compensation and benefit plans as the Company may
institute from time to time.

     5.   Medical and Dental Benefits. The Company agrees to provide to Employee
such hospital, surgical, dental and medical benefits and at a cost that is
normally provided to its other employees under the Company's group health plans.

     6.   Non-Disclosure of Trade Secrets and Confidential Information.
(a) Employee acknowledges that the Company possesses and will continue to
possess and develop information and knowledge that has or will become known to
Employee in connection with the development, manufacture and marketing of the
Company's products and the financing and administration of the Company. All such
information, except such information as is known or becomes known to the public
without violation of this Agreement or other restrictions on its use and
disclosure, is hereinafter referred to as the "Confidential Information". By way
of illustration, but not limitation, the Confidential Information may include
trade secrets, manufacturing processes, formulas, data, engineering and
manufacturing processes, know-how, improvements, discoveries, strategies,
forecasts, projections, proprietary software programs, licenses, prices, costs
and supplier lists, and

                                       1

includes, such information with respect to the Company's proprietary processes
for coating silver/silver chloride plated electrodes which is not in the public
domain.

     (b)  Any and all writings and other physical embodiments of Confidential
Information, including, without limitation, drawings, specifications, recordings
media for machine information-processing systems (such as disks, ROMs, and
tapes), documentation of all types, contracts, reports, manuals, lists,
quotations, proposals, correspondence, notebooks, and samples shall be and
remain the exclusive property of the Company.

     (c)  At all times, both during his employment by the Company and afterward,
Employee will keep in confidence, and will not disclose, any Confidential
Information to anyone, and will not transfer the physical embodiment of any
Confidential Information to anyone, including employees of the Company, except
as authorized by the Company. Employee will use any Confidential Information and
any physical embodiment of Confidential Information to which he has access only
in the course of his work for the Company and for its benefit and will not
appropriate it for the benefit of himself or any third party.

     (d)  Employee will return to the Company all physical embodiments of
Confidential Information, including any copies, in his possession or under his
control, (i) at any time upon the request of the Company, and (ii) without such
a request at the termination for any reason of his employment by the Company.

     (e)  Employee represents that he has not previously disclosed any
information or knowledge that would have fallen within the definition of
"Confidential Information", that he has not transferred the physical embodiment
of such information or knowledge, and that he has not appropriated such
information or knowledge for the benefit of himself or any third party.

     7.   Disclosure and Assignment of Inventions and Works of Authorship.

     (a)  Any discovery, invention, improvement, process, formula, or technique,
whether or not patentable, that Employee made, may make, conceived, or reduced
to practice, either alone or with others, either (i) in the course of performing
work for the Company or at the Company's expense, or (ii) that results from
tasks assigned to him by the Company, or (iii) whose creation ordinarily would
be associated with his then current responsibilities as an employee of the
Company (hereinafter "Proprietary Inventions") shall be the exclusive property
of the Company, and the Company shall be the owner of any patents and other
rights related to Proprietary Inventions. Accordingly, Employee hereby assigns
and conveys to the Company all of his right, title, and interest in and to any
Proprietary Inventions.

     (b)  Employee will promptly disclose to the Company all such Proprietary
Inventions and will help the Company, at its expense, obtain and enforce patents
or Proprietary Inventions in any countries it selects, and Employee will execute
any related documents, including, without limitation, application papers for
patents, assignments, affidavits and oaths of facts within his knowledge, and
assignment of his right, title and interest in and to Proprietary Inventions and
related patent applications and patents to the Company or its designee. Employee
will do any other things the Company requests to convey to, or vest in, the
Company the rights, titles, benefits, and privileges intended to be conveyed.
Employee's obligation under this paragraph shall continue after the termination
of his employment, subject to the Company's compensating him at a reasonable
rate for time actually spent by him at the Company's request after termination.

     (c)  Employee acknowledge that all works of authorship (including, without
limitation, works or authorship that contain software program code) that
Employee produces during, and within the scope of, his employment by the
company, whether they are or are not created on the Company's premises or during
hours in which he is supposed to be rendering services to the Company, are works
made for hire and are the property of the Company, and that copyrights in those
works of authorship are the property of the Company. If for any reason it
appears that the Company is not the author of any such works of authorship for
copyright purposes, Employee hereby expressly assigns all of his rights in and
to that work to the Company and agrees to sign any instrument of specific
assignment requested.

     (d)  If Employee is identified as an inventor in any application for any
United States or foreign patent where the invention (i) is claimed to have been
made, conceived, or reduced to practice during the first year after termination
of his employment by the Company and (ii) would have been a Proprietary
Invention relating to the business of Micron if it occurred before the
termination of his employment, then that invention shall be rebuttably presumed
to be a Proprietary Invention.

                                       2

of such information or knowledge, and that he has not appropriated such
information or knowledge for the benefit of himself or any third party.

     8.   No Conflicting Agreements. Employee attaches to this Agreement, as
Exhibit A, a complete list of any prior agreements with any other person related
to intellectual property rights. If no such list is attached to this Agreement,
Employee represents that there are no such prior agreements. Employee represents

the Company will not breach any other agreement related to intellectual property

officer, employee, representative or consultant, or (ii) individually, or on
behalf of or through any third party, directly or indirectly, solicit, entice or
persuade any other employee of or consultant to the Company to leave the

post-employment prohibitions contained in this paragraph, the other provisions
of this Agreement shall continue in full force and effect.

     10.  Termination.

     (a)  Termination by the Company for Cause. The company may, at its option,
terminate this Agreement by giving written notice of termination to the Employee
without prejudice to any other remedy to which the Company may be entitled
either at law, in equity or under this Agreement, if Employee:

          (i)    shall have committed any material breach of any material
                 provisions or covenants herein, or

          (ii)   shall have committed any act of malfeasance or dishonesty

In the event of the termination of this Agreement prior to the Completion of the
term of employment specified herein, for any of the reasons set forth in this
Paragraph 10(a), the Company shall send written notice to Employee of such
termination and describe in detail the action constituting the act of default or
other reason. Employee shall be entitled to the compensation earned prior to the
date of termination as provided for in this Agreement, computed pro rata up to
and including the date of termination. Employee shall be entitled to no further
compensation under this Agreement after the date of termination.

     (b)  Termination for Other Specified Causes. This Agreement shall terminate
immediately on the occurrence of any one of the following events:

          (i)    The occurrence of circumstances that make it impossible or
                 impracticable for the business of the Company to be continued;

          (ii)   The death of Employee;

          (iii)  The loss by Employee of legal capacity; or

<PAGE>

          (iv)   The continued incapacity (due to a cause other than an
                 industrial accident) on the part of Employee to perform his
                 duties for a continuous period of 180 days, unless waived by
                 the Company.

In the event of the termination of this Agreement prior to the completion of the
term of employment specified herein, for any of the reasons set forth in this
Paragraph 10(b), Employee shall be entitled to the compensation earned prior to
the date of termination as provided for in this Agreement, computed pro rata up
to and including the date of termination.

     (c)  Termination Without Cause by Current Ownership. The Company may
terminate this Agreement at any time by giving thirty (30) days' notice to
Employee. In that event, the Company shall pay to Employee his compensation for
a period of twelve (12) months from the date of termination as provided in
paragraph 4(a) above. Employee shall also be entitled, for a period of twelve
(12) months, to all medical and dental benefits to which he would be entitled if
he remained in the employ of the Company Employee shall not be entitled to any
other severance payment.

     (d)  Termination Without Cause by New Ownership. In the event of a sale of
all or substantially all of the consolidated assets of the Company or a sale or
other transfer of voting securities of the Company which result in the holders
of a majority of the Company's voting securities prior to the transaction not
holding a majority of the Company's voting securities after such transaction,
the Company may terminate this Agreement at any time by giving thirty (30) days'
notice to Employee. In that event, the Company shall pay to Employee the greater
of his current annual base compensation up to the date of termination or his
current annual base compensation for a period of twenty four (24) months.
Employee shall also be entitled, for a period of eighteen (18) months, to all
medical and dental benefits to which he would be entitled to if he remained in
the employ of the Company.

     11.  Remedies for Breach. The parties recognize that the services to be
performed by Employee are special and unique. Accordingly, if Employee breaches
the terms and conditions of this Agreement, or shall threaten a breach of any
such terms and conditions, then the Company shall be entitled to institute legal
and equitable proceedings in any court of competent jurisdiction. The Company
may seek to obtain damages for any breach of this Agreement, to enforce its
specific performance by Employee, or to obtain injunctive relief, without the
necessity of posting a bond, to protect itself from such breach.

     12.  Partial Invalidity. Wherever possible each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law. Moreover, in the event that any one or more of the provisions
hereof shall be held to be excessively broad as to duration, geographic scope,
activity or subject, such provision shall be construed by limiting and reducing
it in accordance with a judgment of a court of competent jurisdiction, so as to
be enforceable under the specific circumstances of the particular case. Such
holding shall, to the extent possible, not affect the validity or enforceability
of any other provision hereof or of this Agreement as a whole. The parties
acknowledge that they have closely examined and carefully negotiated the terms
of this Agreement, deem such terms fair and adequate and wish them to be
preserved.

     13.  Notices. Any notice to be delivered under this Agreement shall be
deemed sufficiently given if in writing and delivered personally or mailed by
certified mail, postage prepaid, to Employee at 5 Hickory Drive, Shrewsbury, MA
01545, and to the Company at 25 Sawyer Passway, Fitchburg, Massachusetts 01420,
or to any changed address that either party may designate by like notice. The
effective date of such notice shall be its mailing date.

     14.  Surviving Clauses. The provisions of Paragraphs 6 (regarding
non-disclosure of trade secrets and confidential information) and 7 (regarding
disclosure and of inventions and works of authorship) will survive the
expiration or termination of this Agreement and will continue in full force and
effect.

     15.  Miscellaneous.

     (a)  Entire Agreement. This Agreement contains the entire agreement between
the parties with respect to its subject matter and supersedes any previous oral
or written communications, representations, understandings or agreements. Any
amendment, modification or waiver of this Agreement shall be effective only if
evidenced by a written instrument executed by both parties, and in the case of
the Company, upon written authorization of the Company's Board of Directors.
Employee's obligations, however, may not be delegated.

     (b)  Binding Effect. All terms and provisions of this Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties, and
their respective heirs, successors, assigns, and legal

                                       4

Company may merge or to which it may transfer all or a substantial part of its
assets, and all the covenants and agreements hereunder shall be binding upon
Employee's heirs, executors, administrators and legal representatives.

     (c)  Non-Waiver. No delay or omission in enforcing any of the terms or
conditions of this Agreement shall be construed as or constitute a waiver
thereof or bar thereto; nor shall a waiver on any one occasion be construed as a
bar to or waiver of any right or remedy on any future occasion.

interpreted in accordance with the laws of the Commonwealth of Massachusetts.

                        2. THE REVOLVING CREDIT FACILITY.

     2.1. Commitment to Lend. Subject to the terms and conditions set forth in
this Credit Agreement, each of the Lenders severally agrees to lend to the
Borrower and the Borrower may borrow, repay, and reborrow from time to time from
the Closing Date up to but not including the Revolving Credit Loan Maturity Date
upon notice by the Borrower to the Administrative Agent given in accordance with
(S)2.6, such sums as are requested by the Borrower up to a maximum aggregate
amount outstanding (after giving effect to all amounts requested) at any one
time equal to such Lender's Commitment minus such Lender's Commitment Percentage
of the sum of the Maximum Drawing Amount and all Unpaid Reimbursement
Obligations, provided that the sum of the outstanding amount of the Revolving
Credit Loans (after giving effect to all amounts requested) plus the Maximum
Drawing Amount and all Unpaid Reimbursement Obligations shall not at any time
exceed the Total Commitment at such time. The Revolving Credit Loans shall be
made pro rata in accordance with each Lender's

<PAGE>

                                      -20-

Commitment Percentage. Each request for a Revolving Credit Loan hereunder shall
constitute a representation and warranty by the Borrower that the conditions set
forth in (S)11 and (S)12, in the case of the initial Revolving Credit Loans to
be made on the Closing Date, and (S)12, in the case of all other Revolving
Credit Loans, have been satisfied on the date of such request.

     2.2. Commitment Fee. The Borrower agrees to pay to the Administrative Agent
for the accounts of the Lenders in accordance with their respective Commitment
Percentages a commitment fee (the "Commitment Fee") calculated at the rate of
one quarter of one percent (1/4%) per annum on the average daily amount during
each calendar quarter or portion thereof from the date hereof to the Revolving
Credit Loan Maturity Date by which the Total Commitment minus the sum of the
Maximum Drawing Amount and all Unpaid Reimbursement Obligations exceeds the
outstanding amount of Revolving Credit Loans during such calendar quarter. The
Commitment Fee shall be payable quarterly in arrears on the first day of each
calendar quarter for the immediately preceding calendar quarter commencing on
the first such date following the date hereof, with a final payment on the
Revolving Credit Loan Maturity Date or any earlier date on which the Commitments
shall terminate.

     2.3. Reduction of Total Commitment. The Borrower shall have the right at
any time and from time to time upon five (5) Business Days prior written notice
to the Administrative Agent to reduce by $1,000,000 or an integral multiple
thereof or to terminate entirely the Total Commitment, whereupon the Commitments
of the Lenders shall be reduced pro rata in accordance with their respective
Commitment Percentages of the amount specified in such notice or, as the case
may be, terminated. Promptly after receiving any notice of the Borrower
delivered pursuant to this (S)2.3, the Administrative Agent will notify the
Lenders of the substance thereof. Upon the effective date of any such reduction
or termination, the Borrower shall pay to the Administrative Agent for the
respective accounts of the Lenders the full amount of any Commitment Fee then
accrued on the amount of the reduction. No reduction or termination of the
Commitments may be reinstated.

     2.4. The Revolving Credit Notes. The Revolving Credit Loans shall be
evidenced by separate promissory notes of the Borrower in substantially the form
of Exhibit A hereto (each a "Revolving Credit Note"), dated as of the Closing
Date (or such other date on which a Lender may become a party hereto in
accordance with (S)15 hereof) and completed with appropriate insertions. One
Revolving Credit Note shall be payable to the order of each Lender in a
principal amount equal to such Lender's Commitment or, if less, the outstanding
amount of all Revolving Credit Loans made by such Lender, plus interest accrued
thereon, as set forth below. The Borrower irrevocably authorizes each Lender to
make or cause to be made, at or about the time of the Drawdown Date of any
Revolving Credit Loan or at the time of receipt of any payment of principal on
such Lender's Revolving Credit Note, an appropriate notation on such Lender's
Record reflecting the making of such Revolving Credit Loan or (as the case may
be) the receipt of such payment. The outstanding amount of the Revolving Credit
Loans set forth on such Lender's Record shall be prima facie evidence of the
principal amount thereof

<PAGE>

                                      -21-

owing and unpaid to such Lender, but the failure to record, or any error in so
recording, any such amount on such Lender's Record shall not limit or otherwise
affect the obligations of the Borrower hereunder or under any Revolving Credit
Note to make payments of principal of or interest on any Revolving Credit Note
when due.

     2.5. Interest on Revolving Credit Loans. Except as otherwise provided
in (S)5.9,

          (a) Each Revolving Credit Loan which is a Base Rate Loan shall bear
     interest for the period commencing with the Drawdown Date thereof and
     ending on the last day of the Interest Period with respect thereto at the
     rate per annum equal to the Base Rate plus the Applicable Margin with
     respect to Base Rate Loans as in effect from time to time.

          (b) Each Revolving Credit Loan which is a LIBOR Rate Loan shall bear
     interest for the period commencing with the Drawdown Date thereof and
     ending on the last day of the Interest Period with respect thereto at the
     rate per annum equal to the LIBOR Rate determined for such Interest Period
     plus the Applicable Margin with respect to LIBOR Rate Loans as in effect
     from time to time.

The Borrower promises to pay interest on each Revolving Credit Loan in arrears
on each Interest Payment Date with respect thereto.

     2.6. Requests for Revolving Credit Loans. The Borrower shall give to the
Administrative Agent written notice in the form of Exhibit B hereto (or
telephonic notice confirmed in a writing in the form of Exhibit B hereto) of
each Revolving Credit Loan requested hereunder (a "Loan Request") no less than
(a) one (1) Business Days prior to the proposed Drawdown Date of any Base Rate
Loan and (b) three (3) LIBOR Business Days prior to the proposed Drawdown Date
of any LIBOR Rate Loan. Each such notice shall specify (i) the principal amount
of the Revolving Credit Loan requested, (ii) the proposed Drawdown Date of such
Revolving Credit Loan, (iii) the Interest Period for such Revolving Credit Loan
and (iv) the Type of such Revolving Credit Loan. Promptly upon receipt of any
such notice, the Administrative Agent shall notify each of the Lenders thereof.
Each Loan Request shall be irrevocable and binding on the Borrower and shall
obligate the Borrower to accept the Revolving Credit Loan requested from the
Lenders on the proposed Drawdown Date. Each Loan Request shall be in a minimum
aggregate amount of $500,000 or an integral multiple thereof.

     2.7. Conversion Options.

          2.7.1. Conversion to Different Type of Revolving Credit Loan. The
     Borrower may elect from time to time to convert any outstanding Revolving
     Credit Loan to a Revolving Credit Loan of another Type, provided that (a)
     with respect to any such conversion of a LIBOR Rate Loan to a Base Rate
     Loan, the Borrower shall give the Administrative Agent at least one (1)
     Business Days prior written notice of such election; (b) with respect to
     any such conversion of a Base Rate Loan to a LIBOR Rate Loan, the Borrower
     shall give the Administrative

<PAGE>

                                      -22-

     Agent at least three (3) LIBOR Business Days prior written notice of such
     election; (c) with respect to any such conversion of a LIBOR Rate Loan into
     a Base Rate Loan, such conversion shall only be made on the last day of the
     Interest Period with respect thereto and (d) no Revolving Credit Loan may
     be converted into a LIBOR Rate Loan when any Default or Event of Default
     has occurred and is continuing. On the date on which such conversion is
     being made each Lender shall take such action as is necessary to transfer
     its Commitment Percentage of such Revolving Credit Loans to its Domestic
     Lending Office or its LIBOR Lending Office, as the case may be. All or any
     part of outstanding Revolving Credit Loans of any Type may be converted
     into a Revolving Credit Loan of another Type as provided herein, provided
     that any partial conversion shall be in an aggregate principal amount of
     $250,000 or a whole multiple of $100,000 in excess thereof, or such lesser
     amount as equals the total amount of the Revolving Credit Loan being
     converted. Each Conversion Request relating to the conversion of a
     Revolving Credit Loan to a LIBOR Rate Loan shall be irrevocable by the
     Borrower.

          2.7.2. Continuation of Type of Revolving Credit Loan. Any Revolving
     Credit Loan of any Type may be continued as a Revolving Credit Loan of the
     same Type upon the expiration of an Interest Period with respect thereto by
     compliance by the Borrower with the notice provisions contained in
     (S)2.7.1; provided that no LIBOR Rate Loan may be continued as such when
     any Default or Event of Default has occurred and is continuing, but shall
     be automatically converted to a Base Rate Loan on the last day of the first
     Interest Period relating thereto ending during the continuance of any
     Default or Event of Default of which officers of the Administrative Agent
     active upon the Borrower's account have actual knowledge. In the event that
     the Borrower fails to provide any such notice with respect to the
     continuation of any LIBOR Rate Loan as such, then such LIBOR Rate Loan
     shall be automatically converted to a Base Rate Loan on the last day of the
     first Interest Period relating thereto. The Administrative Agent shall
     notify the Lenders promptly when any such automatic conversion contemplated
     by this (S).2.7 is scheduled to occur.

          2.7.3. LIBOR Rate Loans. Any conversion to or from LIBOR Rate Loans
     shall be in such amounts and be made pursuant to such elections so that,
     after giving effect thereto, the aggregate principal amount of all LIBOR
     Rate Loans having the same Interest Period shall not be less than $250,000
     or a whole multiple of $100,000 in excess thereof. No more than five (5)
     LIBOR Rate Loans having different Interest Periods may be outstanding at
     any time.

     2.8. Funds for Revolving Credit Loan.

          2.8.1. Funding Procedures. Not later than 11:00 a.m. (Boston time) on
     the proposed Drawdown Date of any Revolving Credit Loans, each of the
     Lenders will make available to the Administrative Agent, at the
     Administrative Agent's Office, in immediately available funds, the amount
     of such Lender's Commitment Percentage of the amount of the requested
     Revolving Credit Loans.

<PAGE>

                                      -23-

     Upon receipt from each Lender of such amount, and upon receipt of the
     documents required by (S)(S)11 and 12 and the satisfaction of the other
     conditions set forth therein, to the extent applicable, the Administrative
     Agent will make available to the Borrower the aggregate amount of such
     Revolving Credit Loans made available to the Administrative Agent by the
     Lenders. The failure or refusal of any Lender to make available to the
     Administrative Agent at the aforesaid time and place on any Drawdown Date
     the amount of its Commitment Percentage of the requested Revolving Credit
     Loans shall not relieve any other Lender from its several obligation
     hereunder to make available to the Administrative Agent the amount of such
     other Lender's Commitment Percentage of any requested Revolving Credit
     Loans.

          2.8.2. Advances by Administrative Agent. The Administrative Agent may,
     unless notified to the contrary by any Lender prior to a Drawdown Date,
     assume that such Lender has made available to the Administrative Agent on
     such Drawdown Date the amount of such Lender's Commitment Percentage of the
     Revolving Credit Loans to be made on such Drawdown Date, and the
     Administrative Agent may (but it shall not be required to), in reliance
     upon such assumption, make available to the Borrower a corresponding
     amount. If any Lender makes available to the Administrative Agent such
     amount on a date after such Drawdown Date, such Lender shall pay to the
     Administrative Agent on demand an amount equal to the product of (a) the
     average computed for the period referred to in clause (c) below, of the
     weighted average interest rate paid by the Administrative Agent for federal
     funds acquired by the Administrative Agent during each day included in such
     period, times (b) the amount of such Lender's Commitment Percentage of such
     Revolving Credit Loans, times (c) a fraction, the numerator of which is the
     number of days that elapse from and including such Drawdown Date to the
     date on which the amount of such Lender's Commitment Percentage of such
     Revolving Credit Loans shall become immediately available to the
     Administrative Agent, and the denominator of which is 360. A statement of
     the Administrative Agent submitted to such Lender with respect to any
     amounts owing under this paragraph shall be prima facie evidence of the
     amount due and owing to the Administrative Agent by such Lender. If the
     amount of such Lender's Commitment Percentage of such Revolving Credit
     Loans is not made available to the Administrative Agent by such Lender
     within three (3) Business Days following such Drawdown Date, the
     Administrative Agent shall be entitled to recover such amount from the
     Borrower on demand, with interest thereon at the rate per annum applicable
     to the Revolving Credit Loans made on such Drawdown Date.

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

     3.1. Maturity. The Borrower promises to pay on the Revolving Credit Loan
Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan Maturity Date, all of the Revolving Credit Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.

<PAGE>

                                      -24-

     3.2. Mandatory Repayments of Revolving Credit Loans. If at any time the sum
of the outstanding amount of the Revolving Credit Loans, the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations exceeds the Total Commitment at
such time, then the Borrower shall immediately pay the amount of such excess to
the Administrative Agent for the respective accounts of the Lenders for
application: first, to any Unpaid Reimbursement Obligations; second, to the
Revolving Credit Loans; and third, to provide to the Administrative Agent cash
collateral for Reimbursement Obligations as contemplated by (S)4.2(b) and (c).
Each payment of any Unpaid Reimbursement Obligations or prepayment of Revolving
Credit Loans shall be allocated among the Lenders, in proportion, as nearly as
practicable, to each Reimbursement Obligation or (as the case may be) the
respective unpaid principal amount of each Lender's Revolving Credit Note, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

     3.3. Optional Repayments of Revolving Credit Loans. The Borrower shall have
the right, at its election, to repay the outstanding amount of the Revolving
Credit Loans, as a whole or in part, at any time without penalty or premium,
provided that any full or partial prepayment of the outstanding amount of any
LIBOR Rate Loans pursuant to this (S)3.3 may be made only on the last day of the
Interest Period relating thereto. The Borrower shall give the Administrative
Agent, no later than 10:00 a.m., Boston time, at least one (1) Business Days
prior written notice of any proposed prepayment pursuant to this (S)3.3 of Base
Rate Loans, and three (3) LIBOR Business Days notice of any proposed prepayment
pursuant to this (S)3.3 of LIBOR Rate Loans, in each case specifying the
proposed date of prepayment of Revolving Credit Loans and the principal amount
to be prepaid. Each such partial prepayment of the Revolving Credit Loans shall
be in an integral multiple of $100,000, shall be accompanied by the payment of
accrued interest on the principal prepaid to the date of prepayment and shall be
applied, in the absence of instruction by the Borrower, first to the principal
of Base Rate Loans and then to the principal of LIBOR Rate Loans. Each partial
prepayment shall be allocated among the Lenders, in proportion, as nearly as
practicable, to the respective unpaid principal amount of each Lender's
Revolving Credit Note, with adjustments to the extent practicable to equalize
any prior repayments not exactly in proportion.

                              4. LETTERS OF CREDIT.

     4.1. Letter of Credit Commitments.

          4.1.1. Commitment to Issue Letters of Credit. Subject to the terms and
     conditions hereof and the execution and delivery by the Borrower of a
     letter of credit application on the Administrative Agent's customary form
     (a "Letter of Credit Application"), the Administrative Agent on behalf of
     the Lenders and in reliance upon the agreement of the Lenders set forth in
     (S)4.1.4 and upon the representations and warranties of the Borrower
     contained herein, agrees, in its individual capacity, to issue, extend and
     renew for the account of the Borrower one or more standby or documentary
     letters of credit (individually, a "Letter of Credit"), in such form as may
     be requested from time to time by the Borrower and agreed to by the
     Administrative Agent; provided, however, that, after giving

<PAGE>

                                      -25-

     effect to such request, (a) the sum of the aggregate Maximum Drawing Amount
     and all Unpaid Reimbursement Obligations shall not exceed $1,000,000 at any
     one time and (b) the sum of (i) the Maximum Drawing Amount on all Letters
     of Credit, (ii) all Unpaid Reimbursement Obligations, and (iii) the amount
     of all Revolving Credit Loans outstanding shall not exceed the Total
     Commitment at such time.

          4.1.2. Letter of Credit Applications. Each Letter of Credit
     Application shall be completed to the satisfaction of the Administrative
     Agent. In the event that any provision of any Letter of Credit Application
     shall be inconsistent with any provision of this Credit Agreement, then the
     provisions of this Credit Agreement shall, to the extent of any such
     inconsistency, govern.

          4.1.3. Terms of Letters of Credit. Each Letter of Credit issued,
     extended or renewed hereunder shall, among other things, (a) provide for
     the payment of sight drafts for honor thereunder when presented in
     accordance with the terms thereof and when accompanied by the documents
     described therein, and (b) have an expiry date no later than the date which
     is fourteen (14) days (or, if the Letter of Credit is confirmed by a
     confirmer or otherwise provides for one or more nominated persons,
     forty-five (45) days) prior to the Revolving Credit Loan Maturity Date.
     Each Letter of Credit so issued, extended or renewed shall be subject to
     the Uniform Customs and Practice for Documentary Credits (1993 Revision),
     International Chamber of Commerce Publication No. 500 or any successor
     version thereto adopted by the Administrative Agent in the ordinary course
     of its business as a letter of credit issuer and in effect at the time of
     issuance of such Letter of Credit (the "Uniform Customs") or, in the case
     of a standby Letter of Credit, either the Uniform Customs or the
     International Standby Practices (ISP98), International Chamber of Commerce
     Publication No. 590, or any successor code of standby letter of credit
     practices among banks adopted by the Administrative Agent in the ordinary
     course of its business as a standby letter of credit issuer and in effect
     at the time of issuance of such Letter of Credit.

          4.1.4. Reimbursement Obligations of Lenders. Each Lender severally
     agrees that it shall be absolutely liable, without regard to the occurrence
     of any Default or Event of Default or any other condition precedent
     whatsoever, to the extent of such Lender's Commitment Percentage, to
     reimburse the Administrative Agent on demand for the amount of each draft
     paid by the Administrative Agent under each Letter of Credit to the extent
     that such amount is not reimbursed by the Borrower pursuant to (S)4.2 (such
     agreement for a Lender being called herein the "Letter of Credit
     Participation" of such Lender).

          4.1.5. Participations of Lenders. Each such payment made by a Lender
     shall be treated as the purchase by such Lender of a participating interest
     in the Borrower's Reimbursement Obligation under (S)4.2 in an amount equal
     to such payment. Each Lender shall share in accordance with its
     participating interest in any interest which accrues pursuant to (S)4.2.

<PAGE>

                                      -26-

         4.2. Reimbursement Obligation of the Borrower. In order to induce the
Administrative Agent to issue, extend and renew each Letter of Credit and the
Lenders to participate therein, the Borrower hereby agrees to reimburse or pay
to the Administrative Agent, for the account of the Administrative Agent or (as
the case may be) the Lenders, with respect to each Letter of Credit issued,
extended or renewed by the Administrative Agent hereunder,

                  (a) except as otherwise expressly provided in (S)4.2(b) and
         (c), on each date that any draft presented under such Letter of Credit
         is honored by the Administrative Agent, or the Administrative Agent
         otherwise makes a payment with respect thereto, (i) the amount paid by
         the Administrative Agent under or with respect to such Letter of
         Credit, and (ii) the amount of any taxes, fees, charges or other costs
         and expenses whatsoever incurred by the Administrative Agent or any
         Lender in connection with any payment made by the Administrative Agent
         or any Lender under, or with respect to, such Letter of Credit,

                  (b) upon the reduction (but not termination) of the Total
         Commitment to an amount less than the Maximum Drawing Amount, an amount
         equal to such difference, which amount shall be held by the
         Administrative Agent for the benefit of the Lenders and the
         Administrative Agent as cash collateral for all Reimbursement
         Obligations, and

                  (c) upon the termination of the Total Commitment, or the
         acceleration of the Reimbursement Obligations with respect to all
         Letters of Credit in accordance with (S)13, an amount equal to the
         then Maximum Drawing Amount on all Letters of Credit, which amount
         shall be held by the Administrative Agent for the benefit of the
         Lenders and the Administrative Agent as cash collateral for all
         Reimbursement Obligations.

Each such payment shall be made to the Administrative Agent at the
Administrative Agent's Office in immediately available funds. Interest on any
and all amounts remaining unpaid by the Borrower under this (S)4.2 at any time
from the date such amounts become due and payable (whether as stated in this
(S)4.2, by acceleration or otherwise) until payment in full (whether before or
after judgment) shall be payable to the Administrative Agent on demand at the
rate specified in (S)5.9 for overdue principal on the Revolving Credit Loans.

         4.3. Letter of Credit Payments. If any draft shall be presented or
other demand for payment shall be made under any Letter of Credit, the
Administrative Agent shall notify the Borrower of the date and amount of the
draft presented or demand for payment and of the date and time when it expects
to pay such draft or honor such demand for payment. If the Borrower fails to
reimburse the Administrative Agent as provided in (S)4.2 on or before the date
that such draft is paid or other payment is made by the Administrative Agent,
the Administrative Agent may at any time thereafter notify the Lenders of the
amount of any such Unpaid Reimbursement Obligation. No later than 3:00 p.m.
(Boston time) on the Business Day next following the receipt of such

<PAGE>
                                      -27-

notice, each Lender shall make available to the Administrative Agent, at the
Administrative Agent's Office, in immediately available funds, such Lender's
Commitment Percentage of such Unpaid Reimbursement Obligation, together with an
amount equal to the product of (a) the average, computed for the period referred
to in clause (c) below, of the weighted average interest rate paid by the
Administrative Agent for federal funds acquired by the Administrative Agent
during each day included in such period, times (b) the amount equal to such
Lender's Commitment Percentage of such Unpaid Reimbursement Obligation, times
(c) a fraction, the numerator of which is the number of days that elapse from
and including the date the Administrative Agent paid the draft presented for
honor or otherwise made payment to the date on which such Lender's Commitment
Percentage of such Unpaid Reimbursement Obligation shall become immediately
available to the Administrative Agent, and the denominator of which is 360. The
responsibility of the Administrative Agent to the Borrower and the Lenders shall
be only to determine that the documents (including each draft) delivered under
each Letter of Credit in connection with such presentment shall be in conformity
in all material respects with such Letter of Credit.

         4.4. Obligations Absolute. The Borrower's obligations under this (S)4
shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Administrative Agent, any
Lender or any beneficiary of a Letter of Credit. The Borrower further agrees
with the Administrative Agent and the Lenders that the Administrative Agent and
the Lenders shall not be responsible for, and the Borrower's Reimbursement
Obligations under (S)4.2 shall not be affected by, among other things, the
validity or genuineness of documents or of any endorsements thereon, even if
such documents should in fact prove to be in any or all respects invalid,
fraudulent or forged, or any dispute between or among the Borrower, the
beneficiary of any Letter of Credit or any financing institution or other party
to which any Letter of Credit may be transferred or any claims or defenses
whatsoever of the Borrower against the beneficiary of any Letter of Credit or
any such transferee. The Administrative Agent and the Lenders shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit. The Borrower agrees that any action taken or omitted by
the Administrative Agent or any Lender under or in connection with each Letter
of Credit and the related drafts and documents, if done in good faith, shall be
binding upon the Borrower and shall not result in any liability on the part of
the Administrative Agent or any Lender to the Borrower. Nothing contained in
this (S)4.4 shall in any manner limit or otherwise affect any claims the
Borrower may have against the Administrative Agent arising from the gross
negligence or willful misconduct of the Administrative Agent as the issuer of
any Letter of Credit.

         4.5. Reliance by Issuer. To the extent not inconsistent with (S)4.4,
the Administrative Agent shall be entitled to rely, and shall be fully protected
in relying upon, any Letter of Credit, draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement,

<PAGE>

                                      -28-

order or other document 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, independent accountants and other experts selected
by the Administrative Agent.

         4.6. Letter of Credit Fee. The Borrower shall, on the date of issuance
or any extension or renewal of any Letter of Credit pay a fee (in each case, a
"Letter of Credit Fee") to the Administrative Agent in respect of each Letter of
Credit an amount equal to the Applicable Margin per annum with respect to Letter
of Credit Fees of the face amount of such Letter of Credit, of which an amount
equal to one eighth of one percent (1/8%) per annum of the face amount of such
Letter of Credit shall be for the account of the Administrative Agent, as a
fronting fee, and the balance of which Letter of Credit Fee shall be for the
accounts of the Lenders in accordance with their respective Commitment
Percentages. In respect of each Letter of Credit, the Borrower shall also pay to
the Administrative Agent for the Administrative Agent's own account, at such
other time or times as such charges are customarily made by the Administrative
Agent, the Administrative Agent's customary issuance, amendment, negotiation or
document examination and other administrative fees as in effect from time to
time.

                         5. CERTAIN GENERAL PROVISIONS.

         5.1.  Funds for Payments.

                  5.1.1. Payments to Administrative Agent. All payments of
         principal, interest, Reimbursement Obligations, Fees and any other
         amounts due hereunder or under any of the other Loan Documents shall be
         made on the due date thereof to the Administrative Agent in Dollars,
         for the respective accounts of the Lenders and the Administrative
         Agent, at the Administrative Agent's Office or at such other place that
         the Administrative Agent may from time to time designate, in each case
         at or about 11:00 a.m. (Boston, Massachusetts, time or other local time
         at the place of payment) and in immediately available funds.

                  5.1.2. No Offset, etc. All payments by the Borrower hereunder
         and under any of the other Loan Documents shall be made without
         recoupment, setoff or counterclaim and free and clear of and without
         deduction for any taxes, levies, imposts, duties, charges, fees,
         deductions, withholdings, compulsory loans, restrictions or conditions
         of any nature now or hereafter imposed or levied by any jurisdiction or
         any political subdivision thereof or taxing or other authority therein
         unless the Borrower is compelled by law to make such deduction or
         withholding. If any such obligation is imposed upon the Borrower with
         respect to any amount payable by it hereunder or under any of the other
         Loan Documents, the Borrower will pay to the Administrative Agent, for
         the account of the Lenders or (as the case may be) the Administrative
         Agent, on the date on which such amount is due and payable hereunder or
         under such other Loan Document, such additional amount in Dollars as
         shall be necessary to enable the Lenders or the Administrative Agent to
         receive the same net amount which the Lenders or the Administrative
         Agent would have received on such

<PAGE>

                                      -29-

         due date had no such obligation been imposed upon the Borrower. The
         Borrower will deliver promptly to the Administrative Agent
         certificates or other valid vouchers for all taxes or other charges
         deducted from or paid with respect to payments made by the Borrower
         hereunder or under such other Loan Document.

                  5.1.3. Non-U.S. Lenders. Each Lender and the Administrative
         Agent that is not a U.S. Person as defined in Section 7701(a)(30) of
         the Code for federal income tax purposes (a "Non-U.S. Lender") hereby
         agrees that, if and to the extent it is legally able to do so, it
         shall, prior to the date of the first payment by the Borrower hereunder
         to be made to such Lender or the Administrative Agent or for such
         Lender's or the Administrative Agent's account, deliver to the Borrower
         and the Administrative Agent, as applicable, such certificates,
         documents or other evidence, as and when required by the Code or
         Treasury Regulations issued pursuant thereto, including (a) in the case
         of a Non-U.S. Lender that is a "bank" for purposes of Section
         881(c)(3)(A) of the Code, two (2) duly completed copies of Internal
         Revenue Service Form W-8BEN or Form W-8ECI and any other certificate or
         statement of exemption required by Treasury Regulations, or any
         subsequent versions thereof or successors thereto, properly completed
         and duly executed by such Lender or the Administrative Agent
         establishing that with respect to payments of principal, interest or
         fees hereunder it is (i) not subject to United States federal
         withholding tax under the Code because such payment is effectively
         connected with the conduct by such Lender or Administrative Agent of a
         trade or business in the United States or (ii) totally exempt or
         partially exempt from United States federal withholding tax under a
         provision of an applicable tax treaty and (b) in the case of a Non-U.S.
         Lender that is not a "bank" for purposes of Section 881(c)(3)(A) of the
         Code, a certificate in form and substance reasonably satisfactory to
         the Administrative Agent and the Borrower and to the effect that (i)
         such Non-U.S. Lender is not a "bank" for purposes of Section
         881(c)(3)(A) of the Code, is not subject to regulatory or other legal
         requirements as a bank in any jurisdiction, and has not been treated as
         a bank for purposes of any tax, securities law or other filing or
         submission made to any governmental authority, any application made to
         a rating agency or qualification for any exemption from any tax,
         securities law or other legal requirements, (ii) is not a ten (10)
         percent shareholder for purposes of Section 881(c)(3)(B) of the Code
         and (iii) is not a controlled foreign corporation receiving interest
         from a related person for purposes of Section 881(c)(3)(C) of the Code,
         together with a properly completed Internal Revenue Service Form W-8 or
         W-9, as applicable (or successor forms). Each Lender or the
         Administrative Agent agrees that it shall, promptly upon a change of
         its lending office or the selection of any additional lending office,
         to the extent the forms previously delivered by it pursuant to this
         section are no longer effective, and promptly upon the Borrower's or
         the Administrative Agent's reasonable request after the occurrence of
         any other event (including the passage of time) requiring the delivery
         of a Form W-8BEN, Form W-8ECI, Form W-8 or W-9 in addition to or in
         replacement of the forms previously delivered, deliver to the Borrower
         and the

<PAGE>
                                      -30-

         Administrative Agent, as applicable, if and to the extent it is
         properly entitled to do so, a properly completed and executed Form
         W-8BEN, Form W-8ECI, Form W-8 or W-9, as applicable (or any successor
         forms thereto). The Borrower shall not be required to pay any
         additional amounts to any Non-U.S. Lender in respect of United States
         federal withholding tax pursuant to (S)5.1.2 above to the extent that
         the obligation to pay such additional amounts would not have arisen
         but for a failure by such Non-U.S. Lender to comply with the
         provisions of this (S)5.1.3; provided, however, that the foregoing
         shall not relieve the Borrower of its obligation to pay additional
         amounts pursuant to (S)5.1.2 in the event that, as a result of any
         change in any applicable law, treaty or governmental rule, regulation
         or order, or any change in interpretation, administration or
         application thereof, a Non-US Lender that was previously entitled to
         receive all payments under this Credit Agreement and the Revolving
         Credit Notes without deduction or withholding of any United States
         federal income taxes is no longer properly entitled to deliver forms,
         certificates or other evidence at a subsequent date establishing the
         fact that such Lender is not subject to withholding.

         5.2. Computations. All computations of interest on the Revolving Credit
Loans and of Fees shall, unless otherwise expressly provided herein, be based on
a 360-day year and paid for the actual number of days elapsed. Except as
otherwise provided in the definition of the term "Interest Period" with respect
to LIBOR Rate Loans, whenever a payment hereunder or under any of the other Loan
Documents becomes due on a day that is not a Business Day, the due date for such
payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension. The outstanding amount of the Revolving
Credit Loans as reflected on the Records from time to time shall be considered
correct and binding on the Borrower unless within five (5) Business Days after
receipt of any notice by the Administrative Agent or any of the Lenders of such
outstanding amount, the Borrower shall notify the Administrative Agent or such
Lender to the contrary.

         5.3. Inability to Determine LIBOR Rate. In the event, prior to the
commencement of any Interest Period relating to any LIBOR Rate Loan, the
Administrative Agent shall determine or be notified by the Required Lenders that
(a) adequate and reasonable methods do not exist for ascertaining the LIBOR Rate
that would otherwise determine the rate of interest to be applicable to any
LIBOR Rate Loan during any Interest Period or (b) the LIBOR Rate determined or
to be determined for such Interest Period will not adequately and fairly reflect
the cost to the Lenders of making or maintaining their LIBOR Rate Loans during
such period, the Administrative Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Lenders) to the Borrower and the Lenders. In such event (i) any Loan Request or
Conversion Request with respect to LIBOR Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (ii) each LIBOR
Rate Loan will automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (iii) the obligations of
the Lenders to make LIBOR Rate Loans shall be suspended until the Administrative
Agent or the Required Lenders determine that the circumstances giving rise to
such suspension no

<PAGE>
                                      -31-

longer exist, whereupon the Administrative Agent or, as the case may be, the
Administrative Agent upon the instruction of the Required Lenders, shall so
notify the Borrower and the Lenders.

         5.4. Illegality. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
LIBOR Rate Loans, such Lender shall forthwith give notice of such circumstances
to the Borrower and the other Lenders and thereupon (a) the commitment of such
Lender to make LIBOR Rate Loans or convert Base Rate Loans to LIBOR Rate Loans
shall forthwith be suspended and (b) such Lender's Revolving Credit Loans then
outstanding as LIBOR Rate Loans, if any, shall be converted automatically to
Base Rate Loans on the last day of each Interest Period applicable to such LIBOR
Rate Loans or within such earlier period as may be required by law. The Borrower
hereby agrees promptly to pay the Administrative Agent for the account of such
Lender, upon demand by such Lender, any additional amounts necessary to
compensate such Lender for any costs incurred by such Lender in making any
conversion in accordance with this (S)5.4, including any interest or fees
payable by such Lender to lenders of funds obtained by it in order to make or
maintain its LIBOR Rate Loans hereunder.

         5.5. Additional Costs, etc. If any present or future applicable law,
which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Lender or the Administrative Agent by any central bank
or other fiscal, monetary or other authority (whether or not having the force of
law), shall:

                  (a) subject any Lender or the Administrative Agent to any tax,
         levy, impost, duty, charge, fee, deduction or withholding of any nature
         with respect to this Credit Agreement, the other Loan Documents, any
         Letters of Credit, such Lender's Commitment or the Revolving Credit
         Loans (other than taxes based upon or measured by the income or profits
         of such Lender or the Administrative Agent), or

                  (b) materially change the basis of taxation (except for
         changes in taxes on income or profits) of payments to any Lender of the
         principal of or the interest on any Revolving Credit Loans or any other
         amounts payable to any Lender or the Administrative Agent under this
         Credit Agreement or any of the other Loan Documents, or

                  (c) impose or increase or render applicable (other than to the
         extent specifically provided for elsewhere in this Credit Agreement)
         any special deposit, reserve, assessment, liquidity, capital adequacy
         or other similar requirements (whether or not having the force of law)
         against assets held by, or

<PAGE>

                                      -32-

         deposits in or for the account of, or loans by, or letters of credit
         issued by, or commitments of an office of any Lender, or

                  (d) impose on any Lender or the Administrative Agent any other
         conditions or requirements with respect to this Credit Agreement, the
         other Loan Documents, any Letters of Credit, the Revolving Credit
         Loans, such Lender's Commitment, or any class of loans, letters of
         credit or commitments of which any of the Revolving Credit Loans or
         such Lender's Commitment forms a part, and the result of any of the
         foregoing is

                           (i)   to increase the cost to any Lender of making,
                  funding, issuing, renewing, extending or maintaining any of
                  the Revolving Credit Loans or such Lender's Commitment or any
                  Letter of Credit, or

                           (ii)  to reduce the amount of principal, interest,
                  Reimbursement Obligation or other amount payable to such
                  Lender or the Administrative Agent hereunder on account of
                  such Lender's Commitment, any Letter of Credit or any of the
                  Revolving Credit Loans, or

                           (iii) to require such Lender or the Administrative
                  Agent to make any payment or to forego any interest or
                  Reimbursement Obligation or other sum payable hereunder, the
                  amount of which payment or foregone interest or Reimbursement
                  Obligation or other sum is calculated by reference to the
                  gross amount of any sum receivable or deemed received by such
                  Lender or the Administrative Agent from the Borrower
                  hereunder,

then, and in each such case, the Borrower will, upon demand made by such Lender
or (as the case may be) the Administrative Agent at any time and from time to
time and as often as the occasion therefor may arise, pay to such Lender or the
Administrative Agent such additional amounts as will be sufficient to compensate
such Lender or the Administrative Agent for such additional cost, reduction,
payment or foregone interest or Reimbursement Obligation or other sum, provided
that the Borrower shall not be liable to any Lender or the Administrative Agent
for costs incurred more than one hundred eighty (180) days prior to receipt by
the Borrower of such demand for payment from such Lender or, as the case may be,
the Administrative Agent, unless such costs were incurred prior to such one
hundred eighty (180) day period as a result of such present or future applicable
law being retroactive to a date which occurred prior to such one hundred eighty
(180) day period and such Lender or, as the case may be, the Administrative
Agent, has given notice to the Borrower of the effectiveness of such law within
one hundred eighty (180) days after the effective date thereof.

         5.6. Capital Adequacy. If after the date hereof any Lender or the
Administrative Agent determines that (a) the adoption of or change in any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) regarding capital requirements for banks or bank
holding companies or any change in

<PAGE>
                                      -33-

the interpretation or application thereof by a Governmental Authority with
appropriate jurisdiction, or (b) compliance by such Lender or the Administrative
Agent or any corporation controlling such Lender or the Administrative Agent
with any law, governmental rule, regulation, policy, guideline or directive
(whether or not having the force of law) of any such entity regarding capital
adequacy, has the effect of reducing the return on such Lender's or the
Administrative Agent's commitment with respect to any Revolving Credit Loans to
a level below that which such Lender or the Administrative Agent could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or the Administrative Agent's then existing policies with respect
to capital adequacy and assuming full utilization of such entity's capital) by
any amount deemed by such Lender or (as the case may be) the Administrative
Agent to be material, then such Lender or the Administrative Agent may notify
the Borrower of such fact. To the extent that the amount of such reduction in
the return on capital is not reflected in the Base Rate, the Borrower and such
Lender shall thereafter attempt to negotiate in good faith, within thirty (30)
days of the day on which the Borrower receives such notice, an adjustment
payable hereunder that will adequately compensate such Lender in light of these
circumstances. If the Borrower and such Lender are unable to agree to such
adjustment within thirty (30) days of the date on which the Borrower receives
such notice, then commencing on the date of such notice (but not earlier than
the effective date of any such increased capital requirement), the fees payable
hereunder shall increase by an amount that will, in such Lender's reasonable
determination, provide adequate compensation provided that the Borrower shall
not be liable to any Lender or the Administrative Agent for costs incurred more
than one hundred eighty (180) days prior to receipt by the Borrower of the
notice referred to in the immediately preceding sentence from such Lender or the
Administrative Agent, as the case may be. Each Lender shall allocate such cost
increases among its customers in good faith and on an equitable basis.

         5.7. Certificate. A certificate setting forth any additional amounts
payable pursuant to (S)(S)5.5 or 5.6 and a brief explanation of such amounts
which are due, submitted by any Lender or the Administrative Agent to the
Borrower in the time periods set forth above, shall be conclusive, absent
manifest error, that such amounts are due and owing.

         5.8. Indemnity. The Borrower agrees to indemnify each Lender and to
hold each Lender harmless from and against any loss, cost or expense (including
loss of anticipated profits) that such Lender may sustain or incur as a
consequence of (a) default by the Borrower in payment of the principal amount of
or any interest on any LIBOR Rate Loans as and when due and payable, including
any such loss or expense arising from interest or fees payable by such Lender to
lenders of funds obtained by it in order to maintain its LIBOR Rate Loans, (b)
default by the Borrower in making a borrowing or conversion after the Borrower
has given (or is deemed to have given) a Loan Request or a Conversion Request
relating thereto in accordance with (S)2.6 or (S)2.7or (c) the making of any
payment of a LIBOR Rate Loan or the making of any conversion of any such
Revolving Credit Loan to a Base Rate Loan on a day that is not the last day of
the applicable Interest Period with respect thereto, including interest or fees
payable by such

<PAGE>

                                      -34-

Lender to lenders of funds obtained by it in order to maintain any such
Revolving Credit Loans.

         5.9.  Interest After Default.

                  5.9.1. Overdue Amounts. Overdue principal and (to the extent
         permitted by applicable law) interest on the Revolving Credit Loans and
         all other overdue amounts payable hereunder or under any of the other
         Loan Documents shall bear interest compounded monthly and payable on
         demand at a rate per annum equal to two percent (2.00%) above the rate
         of interest then applicable thereto (or, if no rate of interest is then
         applicable thereto, the Base Rate) until such amount shall be paid in
         full (after as well as before judgment).

                  5.9.2. Amounts Not Overdue. During the continuance of an Event
         of Default the principal of the Revolving Credit Loans not overdue
         shall, until such Event of Default has been cured or remedied or such
         Event of Default has been waived by the Required Lenders pursuant to
         (S)16.12, bear interest at a rate per annum equal to the greater of
         (a) two percent (2.00%) above the rate of interest otherwise
         applicable to such Revolving Credit Loans pursuant to (S)2.5 and (b)
         the rate of interest applicable to overdue principal pursuant to
         (S)5.9.1.

         5.10. Replacement of Lenders. If any Lender (an "Affected Lender") (a)
makes demand upon the Borrower for (or if the Borrower is otherwise required to
pay) amounts pursuant to (S)(S)5.5 or 5.6, (b) is unable to make or maintain
LIBOR Rate Loans as a result of a condition described in (S)5.4 or (c) defaults
in its obligation to make Revolving Credit Loans in accordance with the terms of
this Credit Agreement or purchase any Letter of Credit Participation, the
Borrower may, so long as no Default or Event of Default has occurred and is then
continuing, within ninety (90) days of receipt of such demand, notice (or the
occurrence of such other event causing the Borrower to be required to pay such
compensation or causing (S)5.4 to be applicable), or default, as the case may
be, by notice (a "Replacement Notice") in writing to the Administrative Agent
and such Affected Lender (i) request the Affected Lender to cooperate with the
Borrower in obtaining a replacement Lender satisfactory to the Administrative
Agent and the Borrower (the "Replacement Lender"); (ii) request the non-Affected
Lenders to acquire and assume all of the Affected Lender's Revolving Credit
Loans and Commitment as provided herein, but none of such Lenders shall be under
an obligation to do so; or (iii) designate a Replacement Lender approved by the
Administrative Agent, such approval not to be unreasonably withheld or delayed.
If any satisfactory Replacement Lender shall be obtained, and/or if any one or
more of the non-Affected Lenders shall agree to acquire and assume all of the
Affected Lender's Revolving Credit Loans and Commitment, then such Affected
Lender shall assign, in accordance with (S)15, all of its Commitment, Revolving
Credit Loans, Letter of Credit Participations, Revolving Credit Notes and other
rights and obligations under this Credit Agreement and all other Loan Documents
to such Replacement Lender or non-Affected Lenders, as the case may be, in
exchange for payment of the principal amount so assigned and all interest and
fees accrued on the amount so assigned, plus all other Obligations then due and
payable to the Affected Lender; provided, however, that (A) such assignment
shall

<PAGE>

                                      -35-

be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Affected Lender and such Replacement
Lender and/or non-Affected Lenders, as the case may be, and (B) prior to any
such assignment, the Borrower shall have paid to such Affected Lender all
amounts properly demanded and unreimbursed under (S)(S)5.5 and 5.6. Upon the
effective date of such assignment, the Borrower shall issue replacement
Revolving Credit Notes to such Replacement Lender and/or non-Affected Lenders,
as the case may be, and such institution shall become a "Lender" for all
purposes under this Credit Agreement and the other Loan Documents.

                                 6. GUARANTIES.

         6.1.  Guaranties.  The Obligations shall also be guaranteed pursuant to
the terms of the Guaranty.

                       7. REPRESENTATIONS AND WARRANTIES.

         The Borrower represents and warrants to the Lenders and the
Administrative Agent as follows:

         7.1.  Corporate Authority.

                  7.1.1. Incorporation; Good Standing. Each of the Borrower and
         its Subsidiaries (a) is a corporation (or similar business entity) duly
         organized, validly existing and in good standing under the laws of its
         jurisdiction of incorporation or formation, (b) has all requisite
         corporate (or the equivalent company) power to own its property and
         conduct its business as now conducted and as presently contemplated,
         and (c) is in good standing as a foreign corporation (or similar
         business entity) and is duly authorized to do business in each
         jurisdiction where such qualification is necessary except where a
         failure to be so qualified would not have a Material Adverse Effect.

                  7.1.2. Authorization. The execution, delivery and performance
         of this Credit Agreement and the other Loan Documents to which the
         Borrower or any of its Subsidiaries is or is to become a party and the
         transactions contemplated hereby and thereby (a) are within the
         corporate (or the equivalent company) authority of such Person, (b)
         have been duly authorized by all necessary corporate (or the equivalent
         company) proceedings, (c) do not and will not conflict with or result
         in any breach or contravention of any provision of law, statute, rule
         or regulation to which the Borrower or any of its Subsidiaries is
         subject or any judgment, order, writ, injunction, license or permit
         applicable to the Borrower or any of its Subsidiaries and (d) do not
         conflict with any provision of the Governing Documents of, or any
         agreement or other instrument binding upon, the Borrower or any of its
         Subsidiaries.

                  7.1.3. Enforceability. The execution and delivery of this
         Credit Agreement and the other Loan Documents to which the Borrower or
         any of its Subsidiaries is or is to become a party will result in valid
         and legally binding

<PAGE>

                                      -36-

         obligations of such Person enforceable against it in accordance with
         the respective terms and provisions hereof and thereof, except as
         enforceability is limited by bankruptcy, insolvency, reorganization,
         moratorium or other laws relating to or affecting generally the
         enforcement of creditors' rights and except to the extent that
         availability of the remedy of specific performance or injunctive
         relief is subject to the discretion of the court before which any
         proceeding therefor may be brought.

         7.2. Governmental Approvals. The execution, delivery and performance by
the Borrower and any of its Subsidiaries of this Credit Agreement and the other
Loan Documents to which the Borrower or any of its Subsidiaries is or is to
become a party and the transactions contemplated hereby and thereby do not
require the approval or consent of, or filing with, any governmental agency or
authority other than those already obtained.

         7.3. Title to Properties; Leases. Except as indicated on Schedule 7.3
hereto, the Borrower and its Subsidiaries own all of the assets reflected in the
consolidated balance sheet of the Borrower and its Subsidiaries as at the
Balance Sheet Date or acquired since that date (except property and assets sold
or otherwise disposed of in the ordinary course of business since that date),
subject to no Liens or other rights of others, except Permitted Liens.

         7.4.  Financial Statements, Projections and Solvency.

                  7.4.1. Fiscal Year. The Borrower and each of its Subsidiaries
         has a fiscal year which is the twelve months ending on December 31 of
         each calendar year.

                  7.4.2. Financial Statements. There has been furnished to each
         of the Lenders a consolidated balance sheet of the Borrower and its
         Subsidiaries as at the Balance Sheet Date, and a consolidated statement
         of income of the Borrower and its Subsidiaries for the fiscal year then
         ended, certified by PricewaterhouseCoopers LLP. Such balance sheet and
         statement of income have been prepared in accordance with GAAP and
         fairly present the financial condition of the Borrower as at the close
         of business on the date thereof and the results of operations for the
         fiscal year then ended. There are no contingent liabilities of the
         Borrower or any of its Subsidiaries as of such date involving material
         amounts, known to the officers of the Borrower, which were not
         disclosed in such balance sheet and the notes related thereto.

                  7.4.3. Solvency. The Borrower and its Subsidiaries, on a
         consolidated and consolidating basis, both before and after giving
         effect to the transactions contemplated by this Credit Agreement, the
         other Loan Documents and all contribution arrangements among the
         Borrower and its Subsidiaries (a) are solvent, (b) the fair value of
         the property of such Person exceeds its total liabilities (including
         contingent liabilities but without duplication of any underlying
         liability related thereto), (c) the present fair saleable value on a
         going concern basis of the assets of such Person is not less than the
         amount required to

<PAGE>

                                      -37-

         pay its probable liabilities on its debts as they become absolute and
         mature, (d) does not intend to, and does not believe that it will,
         incur debts or liabilities beyond its ability to pay as such debts and
         liabilities mature, and (e) is not engaged, and is not about to engage,
         in business or a transaction for which its property would constitute
         unreasonably small capital.

         7.5. No Material Adverse Changes, etc. Since the Balance Sheet Date
there has been no event or occurrence which has had a Material Adverse Effect.
Since the Balance Sheet Date, the Borrower has not made any Restricted Payment.

         7.6. Franchises, Patents, Copyrights, etc. The Borrower and each of its
Subsidiaries possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, adequate
for the conduct of its business substantially as now conducted without known
conflict with any rights of others.

         7.7. Litigation. Except as set forth in Schedule 7.7 hereto, there are
no actions, suits, proceedings or investigations of any kind pending or
threatened against the Borrower or any of its Subsidiaries before any
Governmental Authority, that, (a) if adversely determined, might, either in any
case or in the aggregate, (i) have a Material Adverse Effect or (ii) materially
impair the right of the Borrower and its Subsidiaries, considered as a whole, to
carry on business substantially as now conducted by them, or result in any
substantial liability not adequately covered by insurance, or for which adequate
reserves are not maintained on the consolidated balance sheet of the Borrower
and its Subsidiaries, or (b) which question the validity of this Credit
Agreement or any of the other Loan Documents, or any action taken or to be taken
pursuant hereto or thereto.

         7.8. No Materially Adverse Contracts, etc. Neither the Borrower nor any
of its Subsidiaries is subject to any Governing Document or other legal
restriction, or any judgment, decree, order, law, statute, rule or regulation
that has or is expected in the future to have a Material Adverse Effect. Neither
the Borrower nor any of its Subsidiaries is a party to any contract or agreement
that has or is expected, in the judgment of the Borrower's officers, to have any
Material Adverse Effect.

         7.9. Compliance with Other Instruments, Laws, etc. Neither the Borrower
nor any of its Subsidiaries is in violation of any provision of its Governing
Documents, or any agreement or instrument to which it may be subject or by which
it or any of its properties may be bound or any decree, order, judgment,
statute, license, rule or regulation, in any of the foregoing cases in a manner
that could result in the imposition of substantial penalties or have a Material
Adverse Effect.

         7.10. Tax Status. The Borrower and its Subsidiaries (a) have made or
filed all federal, state and foreign income and all other tax returns, reports

appropriate proceedings and (c) have set aside on their books provisions
reasonably adequate for the payment of all taxes for periods subsequent to the
periods to which such returns, reports or declarations apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and none of the officers of the Borrower know of any basis for
any such claim.

         7.11. No Event of Default.  No Default or Event of Default has occurred
and is continuing.

         7.12. Holding Company and Investment Company Acts. Neither the Borrower
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"investment company", or an "affiliated company" or a "principal underwriter" of
an "investment company", as such terms are defined in the Investment Company Act
of 1940.

         7.13. Absence of Financing Statements, etc. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future Lien on any assets or property
of the Borrower or any of its Subsidiaries or any rights relating thereto.

         7.14. No Liens. The Borrower is the owner of its property and assets
free from any Lien, except for Permitted Liens.

         7.15. Certain Transactions. Except for arm's length transactions
pursuant to which the Borrower or any of its Subsidiaries makes payments in the
ordinary course of business upon terms no less favorable than the Borrower or
such Subsidiary could obtain from third parties, none of the officers,
directors, or employees of the Borrower or any of its Subsidiaries is presently
a party to any transaction with the Borrower or any of its Subsidiaries (other
than for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Borrower, any corporation, partnership, trust or other entity
in which any officer, director, or any such employee has a substantial interest
or is an officer, director, trustee or partner.

         7.16. Employee Benefit Plans.

                  7.16.1. In General. Each Employee Benefit Plan and each
         Guaranteed Pension Plan has been maintained and operated in compliance
         in all material respects with the provisions of ERISA and all
         Applicable Pension Legislation and, to the extent applicable, the Code,
         including but not limited to the provisions thereunder respecting
         prohibited transactions and the bonding of fiduciaries and other
         persons handling plan funds as required by (S)412 of ERISA.

<PAGE>

                                      -39-

         The Borrower has heretofore delivered to the Administrative Agent the
         most recently completed annual report, Form 5500, with all required
         attachments, and actuarial statement required to be submitted under
         (S)103(d) of ERISA, with respect to each Guaranteed Pension Plan.

                  7.16.2. Terminability of Welfare Plans. No Employee Benefit
         Plan, which is an employee welfare benefit plan within the meaning of
         (S)3(1) or (S)3(2)(B) of ERISA, provides benefit coverage subsequent
         to termination of employment, except as required by Title I, Part 6 of
         ERISA or the applicable state insurance laws. The Borrower may
         terminate each such Plan at any time (or at any time subsequent to the
         expiration of any applicable bargaining agreement) in the discretion of
         the Borrower without liability to any Person other than for claims
         arising prior to termination.

                  7.16.3. Guaranteed Pension Plans. Each contribution required
         to be made to a Guaranteed Pension Plan, whether required to be made to
         avoid the incurrence of an accumulated funding deficiency, the notice
         or lien provisions of (S)302(f) of ERISA, or otherwise, has been
         timely made. No waiver of an accumulated funding deficiency or
         extension of amortization periods has been received with respect to
         any Guaranteed Pension Plan, and neither the Borrower nor any ERISA
         Affiliate is obligated to or has posted security in connection with an
         amendment to a Guaranteed Pension Plan pursuant to (S)307 of ERISA or
         (S)401(a)(29) of the Code. No liability to the PBGC (other than
         required insurance premiums, all of which have been paid) has been
         incurred by the Borrower or any ERISA Affiliate with respect to any
         Guaranteed Pension Plan and there has not been any ERISA Reportable
         Event (other than an ERISA Reportable Event as to which the
         requirement of 30 days notice has been waived), or any other event or
         condition which presents a material risk of termination of any
         Guaranteed Pension Plan by the PBGC. Based on the latest valuation of
         each Guaranteed Pension Plan (which in each case occurred within
         twelve months of the date of this representation), and on the
         actuarial methods and assumptions employed for that valuation, the
         aggregate benefit liabilities of all such Guaranteed Pension Plans
         within the meaning of (S)4001 of ERISA did not exceed the aggregate
         value of the assets of all such Guaranteed Pension Plans, disregarding
         for this purpose the benefit liabilities and assets of any Guaranteed
         Pension Plan with assets in excess of benefit liabilities.

                  7.16.4. Multiemployer Plans. Neither the Borrower nor any
         ERISA Affiliate has incurred any material liability (including
         secondary liability) to any Multiemployer Plan as a result of a
         complete or partial withdrawal from such Multiemployer Plan under
         (S)4201 of ERISA or as a result of a sale of assets described in
         (S)4204 of ERISA. Neither the Borrower nor any ERISA Affiliate has
         been notified that any Multiemployer Plan is in reorganization or
         insolvent under and within the meaning of (S)4241 or (S)4245 of ERISA
         or is at risk of entering reorganization or becoming insolvent, or
         that any Multiemployer Plan intends to terminate or has been
         terminated under (S)4041A of ERISA.

         7.17.  Use of Proceeds.

                  7.17.1. General. The proceeds of the Revolving Credit Loans
         shall be used for working capital and general corporate purposes. The
         Borrower will obtain Letters of Credit solely for working capital and
         general corporate purposes.

                  7.17.2. Regulations U and X. No portion of any Revolving
         Credit Loan is to be used, and no portion of any Letter of Credit is to
         be obtained, for the purpose of purchasing or carrying any "margin
         security" or "margin stock" as such terms are used in Regulations U and
         X of the Board of Governors of the Federal Reserve System, 12 C.F.R.
         Parts 221 and 224.

                  7.17.3. Ineligible Securities. No portion of the proceeds of
         any Revolving Credit Loan is to be used, and no portion of any Letter
         of Credit is to be obtained, for the purpose of knowingly purchasing,
         or providing credit support for the purchase of, during the
         underwriting or placement period or within thirty (30) days thereafter,
         any Ineligible Securities underwritten or privately placed by a
         Financial Affiliate.

         7.18. Environmental Compliance. The Borrower has taken all reasonable
steps to investigate the past and present condition and usage of the Real Estate
and the operations conducted thereon and, based upon such diligent
investigation, has determined that to its knowledge:

                  (a) none of the Borrower, its Subsidiaries or any operator of
         the Real Estate or any operations thereon is in violation, or alleged
         violation, of any judgment, decree, order, law, license, rule or
         regulation pertaining to environmental matters, including without
         limitation, those arising under the Resource Conservation and Recovery
         Act ("RCRA"), the Comprehensive Environmental Response, Compensation
         and Liability Act of 1980 as amended ("CERCLA"), the Superfund
         Amendments and Reauthorization Act of 1986 ("SARA"), the Federal Clean
         Water Act, the Federal Clean Air Act, the Toxic Substances Control Act,
         or any state, local or foreign law, statute, regulation, ordinance,
         order or decree relating to health, safety or the environment
         (hereinafter "Environmental Laws"), which violation would have a
         material adverse effect on the environment or a Material Adverse
         Effect;

                  (b) neither the Borrower nor any of its Subsidiaries has
         received notice from any third party including, without limitation, any
         Governmental Authority, (i) that any one of them has been identified by
         the United States Environmental Protection Agency ("EPA") as a
         potentially responsible party under CERCLA with respect to a site
         listed on the National Priorities List, 40 C.F.R. Part 300 Appendix B;
         (ii) that any hazardous waste, as defined by 42 U.S.C. (S).6903(5), any

         pollutant or contaminant as defined by 42 U.S.C. (S).9601(33) and any
         toxic substances, oil or hazardous materials or other chemicals or
         substances regulated

<PAGE>

     by any Environmental Laws ("Hazardous Substances") which any one of them
     has generated, transported or disposed of has been found at any site at
     which a Governmental Authority has conducted or has ordered that the
     Borrower or any of its Subsidiaries conduct a remedial investigation,
     removal or other response action pursuant to any Environmental Law; or
     (iii) that it is or shall be a named party to any claim, action, cause of
     action, complaint, or legal or administrative proceeding (in each case,
     contingent or otherwise) arising out of any third party's incurrence of
     costs, expenses, losses or damages of any kind whatsoever in connection
     with the release of Hazardous Substances;

     or threatened releases of Hazardous Substances on, upon, into or from the

     properties or the environment; (iv) to the best of the Borrower's
     knowledge, there have been no releases on, upon, from or into any real

     Laws; and

          (d) none of the Borrower and its Subsidiaries or any of the other Real
     Estate is subject to any applicable Environmental Law requiring the
     performance of Hazardous Substances site assessments, or the removal or
     remediation of Hazardous Substances, or the giving of notice to any

     such Plans, disregarding for this purpose the benefit liabilities and
     assets of any such Plan with assets in excess of benefit liabilities; or

business.

     9.13. Inconsistent Agreements. Neither the Borrower nor any of its

     ERISA Reportable Event, or a failure to make a required installment or
     other payment (within the meaning of (S)302(f)(1) of ERISA), provided that
     the Administrative Agent determines in its reasonable discretion that such
     event (A) could be expected to result in liability of the Borrower or any
     of its Subsidiaries to the PBGC or such Guaranteed Pension Plan in an
     aggregate amount exceeding $1,000,000 and (B) could constitute grounds for
     the termination of such Guaranteed Pension Plan by the PBGC, for the

     excess of $100,000; or

<PAGE>

                                      -61-

and payable automatically and without any requirement of notice from the
Administrative Agent or any Lender.

     13.2. Termination of Commitments. If any one or more of the Events of
Default specified in (S)13.1(g) or (S)13.1(h) shall occur, any unused portion of
the credit hereunder shall forthwith terminate and each of the Lenders shall be
relieved of all further obligations to make Revolving Credit Loans to the
Borrower and the Administrative Agent shall be relieved of all further
obligations to issue, extend or renew Letters of Credit. If any other Event of
Default shall have occurred and be continuing, the Administrative Agent may and,
upon the request of the Required Lenders, shall, by notice to the Borrower,
terminate the unused portion of the credit hereunder, and upon such notice being
given such unused portion of the credit hereunder shall terminate immediately
and each of the Lenders shall be relieved of all further obligations to make
Revolving Credit Loans and the Administrative Agent shall be relieved of all
further obligations to issue, extend or renew Letters of Credit. No termination
of the credit hereunder shall relieve the Borrower or any of its Subsidiaries of
any of the Obligations.

     13.3. Remedies. In case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Lenders shall have
accelerated the maturity of the Revolving Credit Loans pursuant to ss.13.1, each
Lender, if owed any amount with respect to the Revolving Credit Loans or the
Reimbursement Obligations, may, with the consent of the Required Lenders but not
otherwise, proceed to protect and enforce its rights by suit in equity, action
at law or other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Credit Agreement and the other Loan
Documents or any instrument pursuant to which the Obligations to such Lender are
evidenced, including as permitted by applicable law the obtaining of the ex
parte appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Lender. No remedy herein conferred upon any
Lender or the Administrative Agent or the holder of any Revolving Credit Note or
purchaser of any Letter of Credit Participation is intended to be exclusive of
any other remedy and each and every remedy shall be cumulative and shall be in
addition to every other remedy given hereunder or now or hereafter existing at
law or in equity or by statute or any other provision of law.

     13.4. Distribution of Proceeds. In the event that, following the occurrence
or during the continuance of any Default or Event of Default, the Administrative
Agent or any Lender, as the case may be, receives any monies in connection with
the enforcement of any of its rights hereunder, such monies shall be distributed
for application as follows:

           (a)  First, to the payment of, or (as the case may be) the
     reimbursement of the Administrative Agent for or in respect of all
     reasonable costs, expenses, disbursements and losses which shall have been
     incurred or sustained by the Administrative Agent in connection with the
     collection of such monies by the Administrative Agent, for the exercise,
     protection or enforcement by the Administrative Agent of all or any of the
     rights, remedies, powers and privileges

<PAGE>

                                      -62-

     of the Administrative Agent under this Credit Agreement or any of the other
     Loan Documents or in support of any provision of adequate indemnity to the
     Administrative Agent against any taxes or liens which by law shall have, or
     may have, priority over the rights of the Administrative Agent to such
     monies;

           (b) Second, to all other Obligations in such order or preference as
     the Required Lenders may determine; provided, however, that (i)
     distributions shall be made (A) pari passu among Obligations with respect
     to the Administrative Agent's Fee and all other Obligations and (B) with
     respect to each type of Obligation owing to the Lenders, such as interest,
     principal, fees and expenses, among the Lenders pro rata, and (ii) the
     Administrative Agent may in its discretion make proper allowance to take
     into account any Obligations not then due and payable;

           (c) Third, upon payment and satisfaction in full or other provisions
     for payment in full satisfactory to the Lenders and the Administrative
     Agent of all of the Obligations, to the payment of any obligations required
     to be paid pursuant to (S)9-608(a)(1)(C) or 9-615(a)(3) of the Uniform
     Commercial Code of the Commonwealth of Massachusetts; and

           (d) Fourth, the excess, if any, shall be returned to the Borrower or
     to such other Persons as are entitled thereto.

                          14. THE ADMINISTRATIVE AGENT.

     14.1. Authorization.

           (a) The Administrative Agent is authorized to take such action on
     behalf of each of the Lenders and to exercise all such powers as are
     hereunder and under any of the other Loan Documents and any related
     documents delegated to the Administrative Agent, together with such powers
     as are reasonably incident thereto, provided that no duties or
     responsibilities not expressly assumed herein or therein shall be implied
     to have been assumed by the Administrative Agent.

           (b) The relationship between the Administrative Agent and each of the
     Lenders is that of an independent contractor. The use of the term
     "Administrative Agent" is for convenience only and is used to describe, as
     a form of convention, the independent contractual relationship between the
     Administrative Agent and each of the Lenders. Nothing contained in this
     Credit Agreement nor the other Loan Documents shall be construed to create
     an agency, trust or other fiduciary relationship between the Administrative
     Agent and any of the Lenders.

           (c) As an independent contractor empowered by the Lenders to exercise
     certain rights and perform certain duties and responsibilities hereunder
     and under the other Loan Documents, the Administrative Agent is
     nevertheless a

<PAGE>

                                      -63-

     "representative" of the Lenders, as that term is defined in Article 1 of
     the Uniform Commercial Code, for purposes of actions for the benefit of the
     Lenders and the Administrative Agent with respect to all collateral
     security and guaranties contemplated by the Loan Documents. Such actions
     include the designation of the Administrative Agent as "secured party",
     "mortgagee" or the like on all financing statements and other documents and
     instruments, whether recorded or otherwise, relating to the attachment,
     perfection, priority or enforcement of any security interests, mortgages or
     deeds of trust in collateral security intended to secure the payment or
     performance of any of the Obligations, all for the benefit of the Lenders
     and the Administrative Agent.

     14.2. Employees and Administrative Agents. The Administrative Agent may
exercise its powers and execute its duties by or through employees or agents and
shall be entitled to take, and to rely on, advice of counsel concerning all
matters pertaining to its rights and duties under this Credit Agreement and the
other Loan Documents. The Administrative Agent may utilize the services of such
Persons as the Administrative Agent in its sole discretion may reasonably
determine, and all reasonable documented fees and expenses of any such Persons
shall be paid by the Borrower.

     14.3. No Liability. Neither the Administrative Agent nor any of its
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent or employee thereof, shall be liable for any
waiver, consent or approval given or any action taken, or omitted to be taken,
in good faith by it or them hereunder or under any of the other Loan Documents,
or in connection herewith or therewith, or be responsible for the consequences
of any oversight or error of judgment whatsoever, except that the Administrative
Agent or such other Person, as the case may be, may be liable for losses due to
its willful misconduct or gross negligence. The Administrative Agent shall be
fully justified in failing or refusing to take any action under this Credit
Agreement unless it shall first have received such advice or concurrence of the
Required Lenders as it reasonably deems appropriate or it shall first be
indemnified to its reasonable 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 Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Credit
Agreement 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
the Lenders and all future holders of the Revolving Credit Notes or of a Letter
of Credit Participation.

     14.4. No Representations.

           14.4.1. General. The Administrative Agent shall not be responsible
     for the execution or validity or enforceability of this Credit Agreement,
     the Revolving Credit Notes, the Letters of Credit, any of the other Loan
     Documents or any instrument at any time constituting, or intended to
     constitute, collateral security for the Revolving Credit Notes, or for the
     value of any such collateral security or for the validity, enforceability
     or collectability of any such amounts owing with respect to the Revolving
     Credit Notes, or for any recitals or

<PAGE>

                                      -64-

     statements, warranties or representations made herein or in any of the
     other Loan Documents or in any certificate or instrument hereafter
     furnished to it by or on behalf of the Borrower or any of its Subsidiaries,
     or be bound to ascertain or inquire as to the performance or observance of
     any of the terms, conditions, covenants or agreements herein or in any
     instrument at any time constituting, or intended to constitute, collateral
     security for the Revolving Credit Notes or to inspect any of the
     properties, books or records of the Borrower or any of its Subsidiaries.
     The Administrative Agent shall not be bound to ascertain whether any
     notice, consent, waiver or request delivered to it by the Borrower or any
     holder of any of the Revolving Credit Notes shall have been duly authorized
     or is true, accurate and complete. The Administrative Agent has not made
     nor does it now make any representations or warranties, express or implied,
     nor does it assume any liability to the Lenders, with respect to the credit
     worthiness or financial conditions of the Borrower or any of its
     Subsidiaries. Each Lender acknowledges that it has, independently and
     without reliance upon the Administrative Agent or any other Lender, and
     based upon such information and documents as it has deemed appropriate,
     made its own credit analysis and decision to enter into this Credit
     Agreement.

           14.4.2. Closing Documentation, etc. For purposes of determining
     compliance with the conditions set forth in (S)11, each Lender that has
     executed this Credit Agreement shall be deemed to have consented to,
     approved or accepted, or to be satisfied with, each document and matter
     either sent, or made available, by the Administrative Agent to such Lender
     for consent, approval, acceptance or satisfaction, or required thereunder
     to be consented to or approved by or acceptable or satisfactory to such
     Lender, unless an officer of the Administrative Agent active upon the
     Borrower's account shall have received notice from such Lender prior to the
     Closing Date specifying such Lender's objection thereto and such objection
     shall not have been withdrawn by notice to the Administrative Agent to such
     effect on or prior to the Closing Date.

     14.5. Payments.

           14.5.1. Payments to Administrative Agent. A payment by the Borrower
     to the Administrative Agent hereunder or any of the other Loan Documents
     for the account of any Lender shall constitute a payment to such Lender.
     The Administrative Agent agrees promptly to distribute to each Lender such
     Lender's pro rata share of payments received by the Administrative Agent
     for the account of the Lenders except as otherwise expressly provided
     herein or in any of the other Loan Documents.

           14.5.2. Distribution by Administrative Agent. If in the opinion of
     the Administrative Agent the distribution of any amount received by it in
     such capacity hereunder, under the Revolving Credit Notes or under any of
     the other Loan Documents might involve it in liability, it may refrain from
     making distribution until its right to make distribution shall have been
     adjudicated by a court of competent jurisdiction. If a court of competent
     jurisdiction shall adjudge

<PAGE>

     that any amount received and distributed by the Administrative Agent is to
     be repaid, each Person to whom any such distribution shall have been made
     shall either repay to the Administrative Agent its proportionate share of
     the amount so adjudged to be repaid or shall pay over the same in such
     manner and to such Persons as shall be determined by such court.

           14.5.3. Delinquent Lenders. Notwithstanding anything to the contrary
     contained in this Credit Agreement or any of the other Loan Documents, any
     Lender that fails (a) to make available to the Administrative Agent its pro
     rata share of any Revolving Credit Loan or to purchase any Letter of Credit
     Participation or (b) to comply with the provisions of (S)16.1 with respect
     to making dispositions and arrangements with the other Lenders, where such
     Lender's share of any payment received, whether by setoff or otherwise, is
     in excess of its pro rata share of such payments due and payable to all of
     the Lenders, in each case as, when and to the full extent required by the
     provisions of this Credit Agreement, shall be deemed delinquent (a
     "Delinquent Lender") and shall be deemed a Delinquent Lender until such
     time as such delinquency is satisfied. A Delinquent Lender shall be deemed
     to have assigned any and all payments due to it from the Borrower, whether
     on account of outstanding Revolving Credit Loans, Unpaid Reimbursement
     Obligations, interest, fees or otherwise, to the remaining nondelinquent
     Lenders for application to, and reduction of, their respective pro rata
     shares of all outstanding Revolving Credit Loans and Unpaid Reimbursement
     Obligations. The Delinquent Lender hereby authorizes the Administrative
     Agent to distribute such payments to the nondelinquent Lenders in
     proportion to their respective pro rata shares of all outstanding Revolving
     Credit Loans and Unpaid Reimbursement Obligations. A Delinquent Lender
     shall be deemed to have satisfied in full a delinquency when and if, as a
     result of application of the assigned payments to all outstanding Revolving
     Credit Loans and Unpaid Reimbursement Obligations of the nondelinquent
     Lenders, the Lenders' respective pro rata shares of all outstanding
     Revolving Credit Loans and Unpaid Reimbursement Obligations have returned
     to those in effect immediately prior to such delinquency and without giving
     effect to the nonpayment causing such delinquency.

     14.6. Holders of Revolving Credit Notes. The Administrative Agent may deem
and treat the payee of any Revolving Credit Note or the purchaser of any Letter
of Credit Participation as the absolute owner or purchaser thereof for all
purposes hereof until it shall have been furnished in writing with a different
name by such payee or by a subsequent holder, assignee or transferee.

     14.7. Indemnity. The Lenders ratably agree hereby to indemnify and hold
harmless the Administrative Agent and its affiliates from and against any and
all claims, actions and suits (whether groundless or otherwise), losses,
damages, costs, expenses (including any expenses for which the Administrative
Agent or such affiliate has not been reimbursed by the Borrower as required by
(S)16.2), and liabilities of every nature and character arising out of or
related to this Credit Agreement, the Revolving Credit

<PAGE>

                                      -66-

Notes, or any of the other Loan Documents or the transactions contemplated or
evidenced hereby or thereby, or the Administrative Agent's actions taken
hereunder or thereunder, except to the extent that any of the same shall be
directly caused by the Administrative Agent's willful misconduct or gross
negligence.

       14.8.  Administrative Agent as Lender. In its individual capacity,
Citizens shall have the same obligations and the same rights, powers and
privileges in respect to its Commitment and the Revolving Credit Loans made by
it, and as the holder of any of the Revolving Credit Notes and as the purchaser
of any Letter of Credit Participations, as it would have were it not also the
Administrative Agent.

       14.9.  Resignation. The Administrative Agent may resign at any time by
giving sixty (60) days prior written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor Administrative Agent. Unless a Default or Event of
Default shall have occurred and be continuing, such successor Administrative
Agent shall be reasonably acceptable to the Borrower. If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a financial institution having a rating of
not less than A or its equivalent by S&P. Upon the acceptance of any appointment
as Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative Agent's
resignation, the provisions of this Credit Agreement and the other Loan
Documents shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Administrative Agent.

       14.10. Notification of Defaults and Events of Default. Each Lender hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Administrative Agent thereof. The Administrative
Agent hereby agrees that upon receipt of any notice under this (S)14.10 it shall
promptly notify the other Lenders of the existence of such Default or Event of
Default.

                           15. SUCCESSORS AND ASSIGNS.

       15.1.  General Conditions. The provisions of this Credit Agreement shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby, except that the Borrower may
not assign or otherwise transfer any of its rights or obligations hereunder
without the prior written consent of each Lender and no Lender may assign or
otherwise transfer any of its rights or obligations hereunder except (a) to an
Eligible Assignee in accordance with the provisions of (S)15.2, (b) by way of
participation in accordance with the provisions of (S)15.4 or (c) by way of
pledge or assignment of a security interest subject to the restrictions of
(S)15.6 (and any other attempted assignment or transfer by any party hereto

<PAGE>

                                      -67-

shall be null and void). Nothing in this Credit Agreement, expressed or implied,
shall be construed to confer upon any Person (other than the parties hereto,
their respective successors and assigns permitted hereby, Participants to the
extent provided in (S)15.4 and, to the extent expressly contemplated hereby, the
Related Parties of each of the Administrative Agent and the Lenders) any legal
or equitable right, remedy or claim under or by reason of this Credit Agreement
or any of the other Loan Documents.

       15.2.  Assignments. Any Lender may at any time assign to one or more
Eligible Assignees all or a portion of its rights and obligations under this
Credit Agreement (including all or a portion of its Commitment and the Revolving
Credit Loans at the time owing to it); provided that (a) except in the case of
an assignment of the entire remaining amount of the assigning Lender's
Commitment and the Revolving Credit Loans at the time owing to it or, in the
case of an assignment to a Lender or a Lender Affiliate, the aggregate amount of
the Commitment (which for this purpose includes Revolving Credit Loans
outstanding thereunder) or, if the applicable Commitment is not then in effect,
the principal outstanding balance of the Revolving Credit Loan of the assigning
Lender subject to each such assignment (determined as of the date on which the
Assignment and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $5,000,000 unless each of the
Administrative Agent and, so long as no Default or Event of Default has occurred
and is continuing, the Borrower otherwise consent (each such consent not to be
unreasonably withheld or delayed); (b) each partial assignment shall be made as
an assignment of a proportionate part of all the assigning Lender's rights and
obligations under this Credit Agreement with respect to the Revolving Credit
Loan or the Commitment assigned; (c) any assignment of a Commitment must be
approved by the Administrative Agent unless the Person that is the proposed
assignee is itself a Lender with a Commitment (whether or not the proposed
assignee would otherwise qualify as an Eligible Assignee); and (d) the parties
to each assignment shall execute and deliver to the Administrative Agent an
Assignment and Acceptance, together with a processing and recordation fee of
$3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to
the Administrative Agent an Administrative Questionnaire. Subject to acceptance
and recording thereof by the Administrative Agent pursuant to (S)15.3, from and
after the effective date specified in each Assignment and Acceptance, the
Eligible Assignee thereunder shall be a party to this Credit Agreement and, to
the extent of the interest assigned by such Assignment and Acceptance have the
rights and obligations of a Lender under this Credit Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Acceptance, be released from its obligations under this
Credit Agreement (and, in the case of an Assignment and Acceptance covering all
of the assigning Lender's rights and obligations under this Credit Agreement,
such Lender shall cease to be a party hereto) but shall continue to be entitled
to the benefits of (S)(S)5.1.2, 5.6, 5.7, 5.9 and 16.3 with respect to facts and
circumstances occurring prior to the effective date of such assignment. Any
assignment or transfer by a Lender of rights or obligations under this Credit
Agreement that does not comply with this paragraph shall be treated for purposes
of this Credit Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with (S)15.4.

<PAGE>

                                      -68-

       15.3.  Register. The Administrative Agent, acting solely for this purpose
as an agent of the Borrower, shall maintain at the Administrative Agent's Office
a copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Revolving Credit Loans owing to, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
the Register shall be conclusive, and the Borrower, the Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Credit Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrower and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

       15.4.  Participations. Any Lender may at any time, without the consent
of, or notice to, the Borrower or the Administrative Agent, sell participations
to any Person (other than a natural person) (each, a "Participant") in all or a
portion of such Lender's rights and/or obligations under this Credit Agreement
(including all or a portion of its Commitment and/or the Revolving Credit Loans
owing to it); provided that (a) such Lender's obligations under this Credit
Agreement shall remain unchanged, (b) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (c) the Borrower, the Administrative Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Credit Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Credit Agreement
and to approve any amendment, modification or waiver of any provision of this
Credit Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, modification or waiver that would reduce the principal of or the
interest rate on any Revolving Credit Loans, extend the term or increase the
amount of the Commitment of such Lender as it relates to such Participant,
reduce the amount of any Commitment Fee or Letter of Credit Fees to which such
Participant is entitled or extend any regularly scheduled payment date for
principal or interest. Subject to (S)15.5, the Borrower agrees that each
Participant shall be entitled to the benefits of (S)(S)5.1.2, 5.6, 5.8 and 5.9
to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to (S)15.2. To the extent permitted by law, each Participant
also shall be entitled to the benefits of (S)16.1 as though it were a Lender,
provided such Participant agrees to be subject to (S)16.1 as though it were a
Lender.

       15.5.  Payments to Participants. A Participant shall not be entitled to
receive any greater payment under (S)(S)5.2.2, 5.6 and 5.7 than the applicable
Lender would have been entitled to receive with respect to the participation
sold to such Participant, unless the sale of the participation to such
Participant is made with the Borrower's prior written consent. A Participant
that would be a Non-U.S. Lender if it were a Lender shall not be entitled to the
benefits of (S)5.2.2 unless the Borrower is notified of the participation sold
to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with (S)5.2.3 as though it were a Lender.

<PAGE>

                                      -69-

       15.6.  Miscellaneous Assignment Provisions. A Lender may at any time
grant a security interest in all or any portion of its rights under this Credit
Agreement to secure obligations of such Lender, including without limitation (a)
any pledge or assignment to secure obligations to any of the twelve Federal
Reserve Banks organized under (S)4 of the Federal Reserve Act, 12 U.S.C. (S)341
and (b) with respect to any Lender that is a Fund, to any lender or any trustee
for, or any other representative of, holders of obligations owed or securities
issued by such Fund as security for such obligations or securities or any
institutional custodian for such Fund or for such lender; provided that no such
grant shall release such Lender from any of its obligations hereunder, provide
any voting rights hereunder to the secured party thereof, substitute any such
secured party for such Lender as a party hereto or affect any rights or
obligations of the Borrower or Administrative Agent hereunder.

       15.7.  Assignee or Participant Affiliated with the Borrower. If any
assignee Lender is an Affiliate of the Borrower, then any such assignee Lender
shall have no right to vote as a Lender hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Administrative Agent pursuant to (S)13.1
or (S)13.2, and the determination of the Required Lenders shall for all purposes
of this Credit Agreement and the other Loan Documents be made without regard to
such assignee Lender's interest in any of the Revolving Credit Loans or
Reimbursement Obligations. If any Lender sells a participating interest in any
of the Revolving Credit Loans or Reimbursement Obligations to a Participant, and
such Participant is the Borrower or an Affiliate of the Borrower, then such
transferor Lender shall promptly notify the Administrative Agent of the sale of
such participation. A transferor Lender shall have no right to vote as a Lender
hereunder or under any of the other Loan Documents for purposes of granting
consents or waivers or for purposes of agreeing to amendments or modifications
to any of the Loan Documents or for purposes of making requests to the
Administrative Agent pursuant to (S)13.1 or (S)13.2 to the extent that such
participation is beneficially owned by the Borrower or any Affiliate of the
Borrower, and the determination of the Required Lenders shall for all purposes
of this Credit Agreement and the other Loan Documents be made without regard to
the interest of such transferor Lender in the Revolving Credit Loans or
Reimbursement Obligations to the extent of such participation.

       15.8.  New Revolving Credit Notes. Upon its receipt of an Assignment and
Acceptance executed by the parties to such assignment, together with each
Revolving Credit Note subject to such assignment, the Administrative Agent shall
(a) record the information contained therein in the Register, and (b) give
prompt notice thereof to the Borrower and the Lenders (other than the assigning
Lender). Within five (5) Business Days after receipt of such notice, the
Borrower, at its own expense, shall execute and deliver to the Administrative
Agent, in exchange for each surrendered Revolving Credit Note, a new Revolving
Credit Note to the order of such Assignee in an amount equal to the amount
assumed by such Assignee pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained some portion of its obligations hereunder, a new
Revolving Credit Note to the order of the assigning Lender in an amount equal to

<PAGE>

                                      -70-

the amount retained by it hereunder. Such new Revolving Credit Notes shall
provide that they are replacements for the surrendered Revolving Credit Notes,
shall be in an aggregate principal amount equal to the aggregate principal
amount of the surrendered Revolving Credit Notes, shall be dated the effective
date of such Assignment and Acceptance and shall otherwise be in substantially
the form of the assigned Revolving Credit Notes. The surrendered Revolving
Credit Notes shall be cancelled and returned to the Borrower.

                     16. PROVISIONS OF GENERAL APPLICATIONS.

       16.1.  Setoff. The Borrower hereby grants to the Administrative Agent and
each of the Lenders a continuing lien, security interest and right of setoff as
security for all liabilities and obligations to the Administrative Agent and
each Lender, whether now existing or hereafter arising, upon and against all
deposits, credits, collateral and property, now or hereafter in the possession,
custody, safekeeping or control of the Administrative Agent or such Lender or
any Lender Affiliate and their successors and assigns or in transit to any of
them. Regardless of the adequacy of any collateral, if any of the Obligations
are due and payable and have not been paid or any Event of Default shall have
occurred, any deposits or other sums credited by or due from any of the Lenders
to the Borrower and any securities or other property of the Borrower in the
possession of such Lender may be applied to or set off by such Lender against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Lender. ANY AND ALL RIGHTS TO REQUIRE
ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER
COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF
SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER
ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders
agree with each other Lender that (a) if an amount to be set off is to be
applied to Indebtedness of the Borrower to such Lender, other than Indebtedness
evidenced by the Revolving Credit Notes held by such Lender or constituting
Reimbursement Obligations owed to such Lender, such amount shall be applied
ratably to such other Indebtedness and to the Indebtedness evidenced by all such
Revolving Credit Notes held by such Lender or constituting Reimbursement
Obligations owed to such Lender, and (b) if such Lender shall receive from the
Borrower, whether by voluntary payment, exercise of the right of setoff,
counterclaim, cross action, enforcement of the claim evidenced by the Revolving
Credit Notes held by, or constituting Reimbursement Obligations owed to, such
Lender by proceedings against the Borrower at law or in equity or by proof
thereof in bankruptcy, reorganization, liquidation, receivership or similar
proceedings, or otherwise, and shall retain and apply to the payment of the
Revolving Credit Note or Revolving Credit Notes held by, or Reimbursement
Obligations owed to, such Lender any amount in excess of its ratable portion of
the payments received by all of the Lenders with respect to the Revolving Credit
Notes held by, and Reimbursement Obligations owed to, all of the Lenders, such
Lender will make such disposition and arrangements with the other Lenders with
respect to such excess, either by way of distribution, pro tanto assignment of
claims, subrogation or otherwise as shall result in each Lender receiving in
respect of

<PAGE>

                                      -71-

the Revolving Credit Notes held by it or Reimbursement Obligations owed it, its
proportionate payment as contemplated by this Credit Agreement; provided that if
all or any part of such excess payment is thereafter recovered from such Lender,
such disposition and arrangements shall be rescinded and the amount restored to
the extent of such recovery, but without interest.

       16.2.  Expenses. The Borrower agrees to pay (a) the reasonable costs of
producing and reproducing this Credit Agreement, the other Loan Documents and
the other agreements and instruments mentioned herein, (b) any taxes (including
any interest and penalties in respect thereto) payable by the Administrative
Agent or any of the Lenders (other than taxes based upon the Administrative
Agent's or any Lender's net income) on or with respect to the transactions
contemplated by this Credit Agreement (the Borrower hereby agreeing to indemnify
the Administrative Agent and each Lender with respect thereto), (c) the
reasonable and documented fees, expenses and disbursements of the Administrative
Agent's Special Counsel or any local counsel to the Administrative Agent
incurred in connection with the preparation, syndication, administration or
interpretation of the Loan Documents and other instruments mentioned herein,
each closing hereunder, any amendments, modifications, approvals, consents or
waivers hereto or hereunder, or the cancellation of any Loan Document upon
payment in full in cash of all of the Obligations or pursuant to any terms of
such Loan Document for providing for such cancellation, (d) the reasonable and
documented fees, expenses and disbursements of the Administrative Agent or any
of its affiliates incurred by the Administrative Agent or such affiliate in
connection with the preparation, syndication, administration or interpretation
of the Loan Documents and other instruments mentioned herein, including all
appraisal and examination charges, (e) all reasonable and documented
out-of-pocket expenses (including without limitation reasonable and documented
attorneys' fees and costs, which attorneys may be employees of any Lender or the
Administrative Agent, and reasonable consulting, accounting, appraisal,
investment bankruptcy and similar professional fees and charges) incurred by any
Lender or the Administrative Agent in connection with (i) the enforcement of or
preservation of rights under any of the Loan Documents against the Borrower or
any of its Subsidiaries or the administration thereof after the occurrence of a
Default or Event of Default and (ii) any litigation, proceeding or dispute
whether arising hereunder or otherwise, in any way related to any Lender's or
the Administrative Agent's relationship with the Borrower or any of its
Subsidiaries and (f) all reasonable and documented fees, expenses and
disbursements of any Lender or the Administrative Agent incurred in connection
with UCC searches. The covenants contained in this ss.16.2 shall survive payment
or satisfaction in full of all other obligations.

       16.3.  Indemnification. The Borrower agrees to indemnify and hold
harmless the Administrative Agent, its affiliates and the Lenders from and
against any and all claims, actions and suits whether groundless or otherwise,
and from and against any and all liabilities, losses, damages and expenses of
every nature and character arising out of this Credit Agreement or any of the
other Loan Documents or the transactions contemplated hereby including, without
limitation, (a) any actual or proposed use by the Borrower or any of its
Subsidiaries of the proceeds of any of the Revolving Credit Loans or Letters of

<PAGE>

                                      -72-

Credit, (b) the reversal or withdrawal of any provisional credits granted by the
Administrative Agent upon the transfer of funds from lock box, bank agency,
concentration accounts or otherwise under any cash management arrangements with
the Borrower or any Subsidiary or in connection with the provisional honoring of
funds transfers, checks or other items, (c) the Borrower or any of its
Subsidiaries entering into or performing this Credit Agreement or any of the
other Loan Documents or (d) with respect to the Borrower and its Subsidiaries
and their respective properties and assets, the violation of any Environmental
Law, the presence, disposal, escape, seepage, leakage, spillage, discharge,
emission, release or threatened release of any Hazardous Substances or any
action, suit, proceeding or investigation brought or threatened with respect to
any Hazardous Substances (including, but not limited to, claims with respect to
wrongful death, personal injury or damage to property), in each case including,
without limitation, the reasonable and documented fees and disbursements of
counsel and allocated costs of internal counsel incurred in connection with any
such investigation, litigation or other proceeding, except to the extent that
any of the foregoing are directly caused by the gross negligence or willful
misconduct of the otherwise indemnified party. In litigation, or the preparation
therefor, the Lenders and the Administrative Agent and its affiliates shall be
entitled to select their own counsel and, in addition to the foregoing
indemnity, the Borrower agrees to pay promptly the reasonable and documented
fees and expenses of such counsel. If, and to the extent that the obligations of
the Borrower under this (S)16.3 are unenforceable for any reason, the Borrower
hereby agrees to make the maximum contribution to the payment in satisfaction of
such obligations which is permissible under applicable law. The covenants
contained in this (S)16.3 shall survive payment or satisfaction in full of all
other Obligations.

       16.4.  Treatment of Certain Confidential Information.

              16.4.1. Confidentiality. Each of the Lenders and the
       Administrative Agent agrees, on behalf of itself and each of its
       affiliates, directors, officers, employees and representatives, to use
       reasonable precautions to keep confidential, in accordance with their
       customary procedures for handling confidential information of the same
       nature and in accordance with safe and sound banking practices, any
       non-public information supplied to it by the Borrower or any of its
       Subsidiaries pursuant to this Credit Agreement that is identified by such
       Person as being confidential at the time the same is delivered to the
       Lenders or the Administrative Agent, provided that nothing herein shall
       limit the disclosure of any such information (a) after such information
       shall have become public other than through a violation of this (S)16.4,

       Lenders, the Administrative Agent or any Financial Affiliate is a party,
       or in connection with the enforcement of rights or remedies hereunder or
       under any other Loan Document, (g) to a Lender Affiliate or a Subsidiary
       or affiliate of the Administrative Agent, (h) to any actual or
       prospective assignee or participant or any actual or prospective
       counterparty (or its advisors) to any swap or derivative transactions
       referenced to credit or other risks or events arising under this Credit
       Agreement or any other Loan Document so long as such assignee,
       participant or counterparty, as the case may be, agrees in writing
       (pursuant to a confidentiality agreement containing the terms set forth
       in this (S)16.4) to be bound by the provisions of (S)16.4 or (i) with the
       consent of the Borrower.

              16.4.2. Prior Notification. Unless specifically prohibited by
       applicable law or court order, each of the Lenders and the Administrative
       Agent shall, prior to disclosure thereof, notify the Borrower of any
       request for disclosure of any such non-public information by any

       the obligations of such Lender under any confidentiality letter in
       respect of this financing signed and delivered by such Lender to the
       Borrower prior to the date hereof and shall be binding upon any assignee
       of, or purchaser of any participation in, any interest in any of the
       Revolving Credit Loans or Reimbursement Obligations from any Lender.

       16.5.  Survival of Covenants, Etc. All covenants, agreements,
representations and warranties made herein, in the Revolving Credit Notes, in
any of the other Loan Documents or in any documents or other papers delivered by
or on behalf of the Borrower or any of its Subsidiaries pursuant hereto shall be
deemed to have been relied upon by the Lenders and the Administrative Agent,
notwithstanding any investigation heretofore or hereafter made by any of them,
and shall survive the making by the Lenders of any of the Loans and the
issuance, extension or renewal of any Letters of Credit, as herein contemplated,
and shall continue in full force and effect so long as any Letter of Credit or
any amount due under this Credit Agreement or the Revolving Credit Notes or any
of the other Loan Documents remains outstanding or any Lender has any obligation
to make any Revolving Credit Loans or the Administrative Agent has any
obligation to issue, extend or renew any Letter of Credit, and for such further
time as may be otherwise expressly specified in this Credit Agreement. All
statements contained in any certificate or other paper delivered to any Lender
or the Administrative Agent at any time by or on behalf of the Borrower or any

waives any right it may have to claim or recover in any litigation referred to

to enforce the foregoing waivers and (b) acknowledges that the Administrative
Agent and the Lenders have been induced to enter into this Credit Agreement, the

<PAGE>

                                      -76-

any term of this Credit Agreement, the other Loan Documents or any other
instrument related hereto or mentioned herein may be amended, and the
performance or observance by the Borrower or any of its Subsidiaries of any
terms of this Credit Agreement, the other Loan Documents or such other
instrument or the continuance of any Default or Event of Default may be waived
(either generally or in a particular instance and either retroactively or
prospectively) with, but only with, the written consent of the Borrower and the
written consent of the Required Lenders. Notwithstanding the foregoing, no
amendment, modification or waiver shall:

              (a) without the written consent of the Borrower and each Lender
       directly affected thereby:

                  (i)   reduce or forgive the principal amount of any Revolving
              Credit Loans or Reimbursement Obligations, or reduce the rate of
              interest on the Revolving Credit Notes or the amount of the
              Commitment Fee or Letter of Credit Fees (other than interest
              accruing pursuant to (S)5.10.2 following the effective date of any
              waiver by the Required Lenders of the Default or Event of Default
              relating thereto);

                  (ii)  increase the amount of such Lender's Commitment or
              extend the expiration date of such Lender's Commitment;

                  (iii) postpone or extend the Revolving Credit Loan Maturity
              Date or any other regularly scheduled dates for payments of
              principal of, or interest on, the Revolving Credit Loans or
              Reimbursement Obligations or any Fees or other amounts payable to
              such Lender (it being understood that (A) a waiver of the
              application of the default rate of interest pursuant to (S)5.10.2,
              and (B) any vote to rescind any acceleration made pursuant to
              (S)13.1 of amounts owing with respect to the Revolving Credit
              Loans and other Obligations shall require only the approval of the
              Required Lenders); and

                  (iv)  other than pursuant to a transaction permitted by the
              terms of this Credit Agreement, release all or substantially all
              of the Guarantors from their guaranty obligations under the
              Guaranties;

              (b) without the written consent of all of the Lenders, amend or
       waive this (S)16.12 or the definition of Required Lenders (it being
       understood that the addition of one or more additional credit facilities,
       the allowance of the credit extensions, interest and fees thereunder to
       share ratably or on a subordinated basis with the Revolving Credit Loans,
       Letters of Credit, interest and Fees in the benefits of the Loan
       Documents and the inclusion of the holders of such facilities in the
       determination of Required Lenders shall require only the approval of the
       Required Lenders);

              (c) without the written consent of the Administrative Agent, amend
       or waive (S)14, the amount or time of payment of the Administrative
       Agent's Fee or

<PAGE>

                                      -77-

       any Letter of Credit Fees payable for the Administrative Agent's account
       or any other provision applicable to the Administrative Agent.

No waiver shall extend to or affect any obligation not expressly waived or
impair any right consequent thereon. No course of dealing or delay or omission
on the part of the Administrative Agent or any Lender in exercising any right
shall operate as a waiver thereof or otherwise be prejudicial thereto. No notice
to or demand upon the Borrower shall entitle the Borrower to other or further
notice or demand in similar or other circumstances.

       16.13. Severability. The provisions of this Credit Agreement are
severable and if any one clause or provision hereof shall be held invalid or
unenforceable in whole or in part in any jurisdiction, then such invalidity or
unenforceability shall affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such clause or provision
in any other jurisdiction, or any other clause or provision of this Credit
Agreement in any jurisdiction.
