revolving credit basis at any time and from time to time prior to the Expiration
Date (as defined below) by making Loans to the Borrower not in excess of
$5,000,000 in the aggregate at any time outstanding, the proceeds of which shall
be used by the Borrower to finance in part the working capital requirements of
the Borrower and the Guarantors; and

     WHEREAS, the Bank is willing to extend such credit to the Borrower, subject
to the terms and conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the foregoing the parties hereto agree
to the following:

I. DEFINITIONS

     SECTION 1.01. Definitions. As used herein, the terms defined in the
preamble shall have the same meaning when used in this Agreement and the
following words and terms shall have the following meanings:

     "Account" or "Accounts" shall have the meaning set forth in the
Security Agreements.

     "Adjusted Eurodollar Rate" shall mean, with respect to any Eurodollar Loan
for any Interest Period, an interest rate per annum (rounded upwards, if
necessary, to the next 1/16 of 1%) equal to the product of (i) the Eurodollar
Rate in effect for such Interest Period and (ii) Eurodollar Reserves. For the
purposes hereof, "Eurodollar Rate" shall mean, for any Interest Period, the rate
(rounded upwards, if necessary to the next 1/16 of 1%) at which dollar deposits
approximately equal to the principal amount of the proposed Eurodollar Loan and
for a duration equal to the applicable proposed Interest Period are offered to
the Bank in immediately available funds in an Interbank Market for eurodollars
at approximately 11:00 a.m., New York City time, two Business Days prior to the
commencement of such Interest Period. For purposes hereof, the term "Eurodollar
Reserves" means a fraction (expressed as a decimal), the numerator of which is
the number one and the denominator of which is the number one minus the
applicable statutory reserve requirements for the Bank (without duplication, but
including, without limitation, basic, supplemental, marginal or emergency
reserves), from time to time in effect under Regulation D 


                                      -1-

<PAGE>


of the Board of Governors of the Federal Reserve System (or any successor) with
respect to eurocurrency funding currently referred to as "Eurocurrency
liabilities" in Regulation D. It is agreed that for purposes hereof any amount
bearing interest at the Eurodollar Rate shall be deemed to constitute a
"Eurocurrency liability" as defined in Regulation D and to be subject to the
reserve requirements of Regulation D, without benefit of credit or proration,
exemptions or offsets which might otherwise be available to the Bank from time
to time under Regulation D.

     "Advance Rate" shall mean 75%, or such other percentage as the Bank may
determine in its reasonable discretion based upon the results of any audit
conducted by the Bank from time to time, provided that, so long as no Default or
Event of Default shall have occurred and be continuing, the Bank shall give the
Borrower 30 days' prior written notice of any change in the Advance Rate.

     "Affiliate" shall mean, with respect to any Person, any corporation,
limited liability company, limited liability partnership, partnership, joint
venture, trust or unincorporated organization which, directly or indirectly,
controls or is controlled by or is under common control with such Person. For
the purposes of this definition "control" of a Person shall mean the power,
direct or indirect, to direct or cause the direction of the management or
policies of such Person whether through the ownership of voting securities, by
contract or otherwise; provided that, in any event, any Person who owns directly
or indirectly 5% or more of the securities having ordinary voting power for the
election of directors or other governing body of a corporation or 5% or more of
the partnership or other ownership interest of any Person (other than as a
limited partner of such other Person) will be deemed to control such corporation
or other Person.

     "Alternate Base Rate" shall mean, for any day, a rate per annum (rounded
upwards, if necessary, to the next 1/16 of 1%) equal to the greater of (a) the
Prime Rate in effect on such day and (b) the Federal Funds Effective Rate in
effect on such day plus 1/2%. "Federal Funds Effective Rate" shall mean, for any
day, the weighted average of the rates on overnight Federal funds transactions
with members of the Federal Reserve System arranged by Federal funds brokers, as
published on the next succeeding Business Day by the Federal Reserve Bank of New
York, or, if such rate is not so published for any day which is a Business Day,
the average of the quotations for the day of such transactions received by the
Bank from three Federal funds brokers of recognized standing selected by it. If
for any reason the Bank shall have determined (which determination shall be
conclusive absent manifest error) that it is unable to ascertain the Federal
Funds Effective Rate for any reason, including the inability or failure of the
Bank to obtain sufficient quotations in accordance with the terms thereof, the
Alternate Base Rate shall be determined without regard to clause (b) of the
first sentence of this definition until the circumstances giving rise to such
inability no longer exist. Any change in the Alternate Base Rate due to a change
in the Prime Rate or the Federal Funds Effective Rate shall be effective on the
effective date of such change in the Prime Rate or the Federal Funds Effective
Rate, as the case may be.

     SECTION 1.02. Accounting Terms. Except as otherwise herein specifically
provided, each accounting term used herein shall have the meaning given to it
under Generally Accepted Accounting Principles. "Generally Accepted Accounting
Principles" or "GAAP" shall mean those generally accepted accounting principles
and practices which are recognized as such by the American Institute of

other appropriate board or committee of the FASB) in order to continue as a
Generally Accepted Accounting Principle or practice may be so changed. Any
dispute or disagreement between the Borrower or any Guarantor and the Bank
relating to the determination of Generally Accepted Accounting Principles shall,

II. LOANS

     SECTION 2.01. Loans. (a) Subject to the terms and conditions, and relying
upon the representations and warranties, set forth herein, the Bank agrees to
make loans (individually a "Loan" and collectively the "Loans") to the Borrower
at any time or from time to time on or after the date hereof and until the
Expiration Date, provided that no Default or Event of Default shall have
occurred and be continuing, in an aggregate principal amount not in excess of
the lesser of (i) $5,000,000 (the "Commitment") and (ii) the current Borrowing
Base as set forth on the most recent Borrowing Base Certificate. Within the

provisions and limitations set forth herein.

     (b) Loans made by the Bank on any one day shall be in any combination of
Alternate Base Rate Loans and Eurodollar Loans, provided, that (i) each
Eurodollar Loan shall be in an amount not less than $500,000 and integral
multiples of $100,000 in excess thereof and (ii) each Alternate Base Rate Loan
shall be in an amount not less than $250,000 and integral multiples of $100,000
in excess thereof unless the available Commitment is less than $250,000, in
which case an Alternate Base Rate Loan may be in the amount of the available
Commitment. The initial Loan by the Bank shall be made against delivery to the
Bank of the Note, payable to the order of the Bank, as described in Section 2.02
hereof and upon delivery of the other documentation required in Article IV
herein.

     (c) Each Alternate Base Rate Loan shall be made upon written, telegraphic

<PAGE>


Business Day on which it is requested, and each Eurodollar Loan shall be made
upon written, telegraphic or facsimile notice from the Borrower to the Bank not
later than 11:00 A.M. New York city time on the day which is three (3) Business
Days prior to the first day of the Interest Period for which such Loan is
requested. Each such notice (a "Notice of Borrowing") shall specify the
requested date, amount and Type of Loan and, in the case of a Eurodollar Loan,
the requested Interest Period. A Notice of Borrowing, once given, shall be
irrevocable.

     SECTION 2.02. Note. The Loans shall be evidenced by a promissory note (the
"Note"), substantially in the form attached hereto as Exhibit A, appropriately
completed, duly executed and delivered on behalf of the Borrower and payable to
the order of the Bank in the principal amount equal to the Commitment. The date
and amount of each Loan, each payment or prepayment of principal of each Loan
and, in the case of a Eurodollar Loan, the interest rate and the Interest Period
shall be recorded on the schedule attached to the Note, and the Borrower hereby
authorizes the Bank to make such recordation. The Note, the schedule or
schedules attached thereto and the books and records of the Bank shall be
presumptive evidence of the Loans, absent manifest error. The aggregate
principal amount outstanding on the Note shall be payable on the Expiration Date
and all accrued and unpaid interest thereon shall, be payable on each Interest
Payment Date.

     SECTION 2.03. Interest on Loans. Each Loan shall bear interest in
accordance with Section 2.08 if it is an Alternate Base Rate Loan and Section
2.10 if it is a Eurodollar Loan.

     SECTION 2.04. Intentionally omitted.

     SECTION 2.05. Intentionally omitted.

     SECTION 2.06. Intentionally omitted.

     SECTION 2.07. Intentionally omitted.

     SECTION 2.08. Interest on Alternate Base Rate Loans. The Borrower shall pay
interest on the unpaid principal amount of each Alternate Base Rate Loan from

Payment Date at an interest rate per annum equal to the Alternate Base Rate.

     SECTION 2.09. Intentionally omitted.

     SECTION 2.10. Interest on Eurodollar Loans. The Borrower shall pay interest
on the unpaid principal amount of each Eurodollar Loan from the Borrowing Date

Adjusted Eurodollar Rate plus the Interest Margin.

                                      -12-


<PAGE>

     SECTION 2.11. Continuation and Conversion of Loans. The Borrower shall have
the right, at any time on three (3) Business Days' prior irrevocable written
notice to the Bank, to continue any Eurodollar Loan or portion thereof into a
subsequent Interest Period and to convert any Loan or portion thereof into a
Loan of a different Type, subject, in the case of a Eurodollar Loan, to the
selection of an Interest Period and, in the case of all Loans, to the following
conditions precedent:

          (a) no portion of the outstanding principal balance of any Loans may
     be continued as, or converted into, Eurodollar Loans when any Event of
     Default shall have occurred and be continuing;

          (b) in the case of a continuation of or conversion of less than all
     the Loans, the aggregate principal amount of Loans continued or converted
     shall be as provided in Section 2.01(b) hereof;

          (c) each conversion shall be effected by the Bank by applying the
     proceeds of the new Loan to the Loan (or portion thereof) being converted,
     and accrued interest on the Loan (or portion thereof) being converted shall
     be paid by the Borrower at the time of conversion; and

          (d) a Eurodollar Loan may be converted to an Alternate Base Rate Loan
     only on the last day of its Interest Period;

          (e) each request for a Eurodollar Loan or a continuation thereof which
     shall fail to state an applicable Interest Period shall be deemed to be a
     request for an Interest Period of a one (1) month; and

          (f) in the event that the Borrower does not give notice to continue
     any Eurodollar Loan into a subsequent Interest Period, the Borrower shall
     be deemed to have requested that such Loan (unless repaid) be converted to
     an Alternate Base Rate Loan at the expiration of the then current Interest
     Period.

     SECTION 2.12. Prepayment of Loans. (a) Subject to the provisions of
Sections 2.12(b), 2.17 and 2.20 hereof, the Borrower may, upon at least one (1)
Business Day's notice in the case of an Alternate Base Rate Loan and five (5)
Business Days' notice to the Bank in the case of a Eurodollar Loan (which notice
shall be in writing and, once given, shall be irrevocable), prepay the
outstanding amount of any Loan in whole or in part with accrued interest to the
date of such prepayment on the amount prepaid; provided, however, that any
prepayment of any Eurodollar Loan shall be made on the last day of an Interest
Period for such Loan; and provided, further, that each partial prepayment of any
Loan shall be in a principal amount not less than $500,000 and

                                      -13-

<PAGE>


integral multiples of $100,000 in excess thereof in the case of a Eurodollar
Loan and $100,000 in the case of Alternate Base Rate Loans.

     (a-1) The Borrower shall prepay the Note on the date of delivery to the
Bank of any Borrowing Base Certificate if (or on such earlier date on which the
Chief Financial Officer shall have become aware that) the outstanding principal
balance of the Note is greater than the then current Borrowing Base (as set
forth on such Borrowing Base Certificate). Such prepayment shall be in an amount
equal to the difference between such Borrowing Base and the outstanding
principal balance of the Note on such date. Each such prepayment shall be
applied first to Alternate Base Rate Loans and thereafter to Eurodollar Loans in
the order of their maturity, provided that, so long as no Default or Event of
Default shall have occurred and be continuing, the Bank will hold the amount of
any such prepayment to be applied to Eurodollar Loans as additional Collateral
in a cash collateral account pledged to the Bank pursuant to the Assignment and
Pledge Agreement and shall apply the same on the last day of the Interest Period
for each such Eurodollar Loan.

     (b) The Borrower shall reimburse the Bank on demand for any loss incurred
by it in the reemployment of the funds released by any prepayment or conversion
of any Eurodollar Loan required or permitted by any provision of this Agreement,
in each case if such Loan is prepaid or converted other than on the last day of
an Interest Period for such Loan. The Borrower further agrees to reimburse the
Bank on demand for any loss incurred by it as a result of (i) Borrower's failure
to prepay pursuant to notice given pursuant to paragraph (a) of this Section
2.12 or as required under paragraph (a-1) of this Section 2.12, (ii) Borrower's
failure to make any regularly scheduled payment of principal of any Eurodollar
Loan or (iii) in the reemployment of the funds released by any refusal by the
Borrower to accept any requested Eurodollar Loan or any requested continuation
thereof or conversion thereto.

     (c) Each prepayment of any Loan shall be accompanied by accrued interest on
the amount of such prepayment to the date thereof.

     SECTION 2.13. Reduction or Termination of the Commitment. The Borrower
shall have the right, upon at least five (5) Business Days' prior written notice
to the Bank, at any time to terminate or from time to time permanently to reduce
the Commitment without premium or penalty; provided, however, that (a) no
reduction of the Commitment shall be less than $500,000, (b) the Commitment may
not be reduced to the extent that following such reduction the unpaid principal
of the Note would exceed the Commitment and (c) any acceleration of the
Expiration Date shall be accompanied by the payment of any Commitment Fee then
accrued hereunder.

                                      -14-

<PAGE>


     SECTION 2.14. Fees. The Borrower agrees to pay to the Bank, in
consideration of its Commitment, a commitment fee ("Commitment Fee") of 1/8 of
1% per annum on the average daily unused portion of the Commitment (based on a
year of 360 days), payable quarterly commencing on the first day of the second
quarter following the Closing Date.

     SECTION 2.15. Late Payments; Interest. Any amount of principal, interest or
any other amounts due hereunder which is not paid when due ("Overdue Payment"),
whether at stated maturity, by acceleration or otherwise, shall, to the extent
permitted by law, bear interest from such due date until the Overdue Payment is
paid in full, which interest shall be payable on demand, at a fluctuating
interest rate per annum equal to 2% in excess of the Alternate Base Rate. On and
after the occurrence and during the continuance of an Event of Default, the rate
of interest applicable to any Loan hereunder shall be increased to 2% above the
rate which would otherwise be applicable to such Loan, except for Overdue
Payments bearing interest as provided in the first sentence of this Section
2.15.

     SECTION 2.16. Application of Payments and Computations. All computations of
the Alternate Base Rate, the Eurodollar Rate and Fees hereunder shall be made by
the Bank on the basis of a year of 360 days, for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest is payable.

     SECTION 2.17. Funds; Manner of Payment. Each Loan and each payment and
prepayment of principal and interest on the Note shall be made in Federal or
other immediately available funds without set-off or counterclaim to the Bank.
Whenever any payment to be made hereunder or under any Note shall be stated to
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or Fees, as the case may be.
The Borrower hereby authorizes the Bank to charge its account #859-111636 for
all principal and interest payments and any Fees due hereunder.

     SECTION 2.18. Capital Adequacy. If the Bank shall have determined that,
after the date hereof, the adoption of any applicable law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or
in the interpretation or administration of any of the foregoing by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Bank (or any
lending office of the Bank) or the Bank's holding company with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on the Bank's capital or on the capital of
the Bank's holding company, if any, as a consequence of its obligations
hereunder to a level below that which the Bank or the Bank's holding company
could have achieved but for such adoption, change, compliance or directive
(taking into consideration the Bank's policies and the policies of the Bank's
holding company with respect to capital adequacy) by an amount

                                      -15-

<PAGE>

deemed by the Bank to be material, then from time to time, upon notice to the
Borrower from the Bank, the Borrower shall pay to the Bank such additional
amount or amounts as will compensate the Bank or the Bank's holding company for
any such reduction suffered. Such notice shall set forth any additional amount
or amounts determined by the Bank to be payable, shall include calculations in
reasonable detail and shall, in the absence of manifest error, be presumptive
evidence of the matters stated therein and be binding upon the Borrower.

     SECTION 2.19. Inability to Determine Rate. In the event, and on each
occasion, that on the day two (2) Business Days prior to the commencement of any
Interest Period for a Eurodollar Loan, the Bank shall have determined (which
determination shall, in the absence of manifest error, be conclusive and binding
upon the Borrower) that dollar deposits in the amount of the principal amount of
such Eurodollar Loan are not generally available in the Interbank Market, or
that the rate at which such dollar deposits are being offered will not
accurately reflect the cost to the Bank of making or funding the principal
amount of a Eurodollar Loan during such Interest Period, or that reasonable
means do not exist for ascertaining the Eurodollar Rate, the Bank shall, as soon
as practicable thereafter, give written, telegraphic, telephonic or facsimile
notice of such determination to the Borrower and any request by the Borrower for
a Eurodollar Loan or for conversion to or continuation of a Eurodollar Loan
shall be deemed a request for an Alternate Base Rate Loan. After such notice
shall have been given, and until the circumstances giving rise to such notice no
longer exist, each request for a Eurodollar Loan shall be deemed to be a request
for an Alternate Base Rate Loan.

     SECTION 2.20. Other Events. (a) In the event that any enactment of or
change after the date hereof in applicable law, regulation, condition, directive
or interpretation thereof (including any request, guideline or policy whether or
not having the force of law and including, without limitation, Regulation D
promulgated by the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect) by any authority charged with the
administration or interpretation thereof:

            (i) subjects the Bank to any tax with respect to the Eurodollar
      Loans hereunder or changes the basis of taxation of payment to the Bank of
      principal of or interest on any Eurodollar Loan or any commitment
      hereunder or any other amounts payable hereunder (other than any tax
      measured by or based upon the overall net income of the Bank or any branch
      or office thereof, imposed by the United States of America or by any other
      jurisdiction in which the Bank is qualified to do business or any
      political subdivision or taxing authority therein); or

            (ii) to the extent not included in the calculation of the Adjusted
      Eurodollar Rate, imposes, modifies or deems applicable any reserve or
      deposit requirements against any assets held by, deposits with or for the
      account of, or loans or commitments by, an office of the Bank in
      connection with payments by the Bank hereunder; or

                                      -16-


<PAGE>

          (iii) imposes upon the Bank or any Interbank Market any other
     condition with respect to any amount paid or payable to or by the Bank in
     connection with Eurodollar Loans pursuant to this Agreement;

and the result of any of the foregoing is to increase the cost to the Bank of
making, continuing or maintaining any Eurodollar Loans or maintaining the
Commitment with respect to Eurodollar Loans, or of converting (or of its
obligation to convert) any portion of the Loans into Eurodollar Loans or to
reduce the amount of any payment receivable by the Bank hereunder in respect of
Eurodollar Loans, in each case by an amount which the Bank in its reasonable
judgment deems material, then:

          (A) the Bank shall promptly notify the Borrower in writing of the
     happening of such event;

          (B) the Bank shall promptly deliver to the Borrower a certificate
     stating the change which has occurred or the reserve requirements or other
     conditions which have been imposed on the Bank or the request, directive or
     requirement with which it has complied, together with the date thereof, the
     amount of such increased cost, reduction or payment and the way in which
     such amount has been calculated; and

          (C) the Borrower shall pay to the Bank, within 30 days after delivery
     of the certificate referred to in clause (B) above, the amount of such
     additional cost, reduction or payment.

The Bank agrees to designate a different office of the Bank as its lending
office for Eurodollar Loans if the designation would avoid or reduce any amount
payable by the Borrower to the Bank pursuant to this paragraph (a); provided,
however, that such designation need not be made if it would result in any
additional costs, expenses or risks to the Bank that are not reimbursed by the
Borrower pursuant hereto or would be in any other respect prejudicial to the
Bank. If the Bank makes a demand for compensation pursuant to this paragraph
(a), the Borrower may at any time, upon at least three (3) Business Days' prior
written or telegraphic notice to the Bank either (i) repay in full any
outstanding Eurodollar Loan together with accrued interest thereon to the date
of prepayment or (ii) convert such Loan to a Loan of a different Type, in either
case, subject to Section 2.12(b) hereof.

     (b) Failure on the part of the Bank to demand compensation under paragraph
(a) above on any one occasion shall not constitute a waiver of its right to
demand such compensation on any other occasion and failure on the part of the
Bank to deliver any certificate in a timely manner shall not in any way reduce
any obligations of the Borrower to the Bank under this Section 2.20.

                                      -17-


<PAGE>


     SECTION 2.21. Change in Legality. (a) Notwithstanding anything to the
contrary contained elsewhere in this Agreement, if any change after the date
hereof in any law or regulation or in the interpretation or application thereof
by any governmental authority charged with the administration thereof shall make
it unlawful (based on the opinion of any counsel, whether in-house, special or
general, for the Bank) for the Bank to make or maintain any Eurodollar Loan or
to give effect to its obligations as contemplated hereby with respect to any
Eurodollar Loan, then, by written notice to the Borrower by the Bank, the Bank
may:

          (i) declare that such Eurodollar Loans will not thereafter be made by
     the Bank hereunder, whereupon the Borrower shall be prohibited from
     requesting such Loans from the Bank hereunder unless such declaration is
     subsequently withdrawn; and the Bank agrees to withdraw any such
     declaration if and to the extent that the making and/or maintenance by the
     Bank of its Eurodollar Loans shall cease to be unlawful; and

          (ii) require that all outstanding Eurodollar Loans made by it to be
     converted to Alternate Base Rate Loans, whereupon all such Loans shall be
     automatically converted to Alternate Base Rate Loans as of the effective
     date of such notice as provided in paragraph (b) below and subject to
     Section 2.12(b) hereof.

     (b) For purposes of this Section 2.21, a notice to the Borrower by the Bank
pursuant to paragraph (a) above shall be effective on the last day of then
current Interest Period or, if required by law, on such earlier date as shall be
so required.

     (c) The Bank agrees to designate a different office of the Bank as its
lending office for Eurodollar Loans if such designation will effect compliance
with the law or regulation or interpretation thereof invoking the provisions of
this Section 2.21; provided, however, that such designation need not be made if
it would result in any additional costs, expenses or risks to the Bank that are
not reimbursed by the Borrower pursuant hereto or would be in any other respect
prejudicial to the Bank.

III. REPRESENTATIONS AND WARRANTIES

the Loan Documents to which it is a party.

     SECTION 3.02. Corporate and Governmental Authorization; No Contravention.

certificate of incorporation or bylaws, (ii) any provision of law or any
governmental rule or regulation applicable to it or, (iii) any order of any

will not be in conflict with, result in a breach of or constitute (with due
notice and/or lapse of time) a default under, any such Material Contract, or

taxes, or any long-term lease or unusual forward or long-term commitment,
including, without limitation, any interest rate or foreign currency swap or

into in the ordinary course of business as currently conducted and would not
result in a Material Adverse Effect.

to the consolidated financial condition of the Borrower and the Guarantors at
May 31, 1996.

     (d) Since May 31, 1996 there has been no development or event, which has
had or could reasonably be expected to have a Material Adverse Effect. It has no
obligation or liability as of the date of this representation, contingent or
otherwise which is material in amount and which was not reflected in the
foregoing statements (and the related notes thereto), unless the same was
entered into in the ordinary course of business as currently conducted and would
not result in a Material Adverse Effect.

     (e) Each of the Borrower and each Guarantor is solvent.

     SECTION 3.04. Taxes. All assessed deficiencies resulting from Internal

appropriate reserves set aside therefor.

     SECTION 3.05. Title to Properties. It has good and marketable title to its
properties and assets reflected on the balance sheets referred to in Section
3.03 hereof, except for such properties and assets as have been disposed of

     or other governmental department, commission, board, bureau, agency or
     instrumentality, domestic or foreign, which involve any of the transactions

     Environmental Laws, (ii) the generation, use, handling, transportation,

     order, decree, judgment, injunction, notice or binding agreement issued,
     promulgated or entered into by any federal, state or local government or

     health and safety matters related to the foregoing.

          "Hazardous Materials" means all explosive or radioactive substances or
     wastes and all hazardous or toxic substances, wastes or other pollutants,
     including petroleum or petroleum distillates, asbestos or asbestos
     containing materials, polychlorinated biphenyls, radon gas, infectious or
     medical wastes and all other substances or wastes of any nature regulated
     pursuant to any Environmental Law.

     SECTION 3.07. Agreements. It is not a party to any agreement or instrument
or subject to any judgment, order, writ, injunction, decree or regulation
materially and adversely affecting its business, properties or assets,

with the applicable provisions of ERISA and the Code. The present value of all
accrued benefits under each Single Employer Plan maintained by the Borrower, any
Guarantor or any Commonly Controlled Entity (based on those assumptions used to
fund the Plans) did not, as of the last annual valuation date prior to the date
on which this representation is made or deemed made, exceed the value of the
assets of such Plan allocable to such accrued benefits. None of the Borrower,
any Guarantor or any Commonly Controlled Entity has had a complete or partial
withdrawal from any Multiemployer Plan, and none of the Borrower, any Guarantor
or any Commonly Controlled Entity would become subject to any liability under
ERISA if such Person were to withdraw completely from all Multiemployer Plans as
of the valuation date most closely preceding the date on which this
representation is made or deemed made. No such Multiemployer Plan is in
reorganization or Insolvent. The present value (determined using actuarial and
other assumptions which are reasonable in respect of the benefits provided and
the employees participating) of the liability of the Borrower, each Guarantor
and each Commonly Controlled Entity for post retirement benefits to be provided
to their current and former employees under Plans which are welfare benefits
plan (as defined in Section 3(1) of ERISA) does not, in the aggregate, exceed
the assets under all such Plans allocable to such benefits.

by the Borrower only for the purposes described in the preamble hereto.

If requested by the Bank under appropriate circumstances and as required by law,
it, or any Subsidiary, will furnish to the Bank a statement on Federal Reserve
Form U-1.

     (b) No part of the proceeds of the Loans will be used, whether directly or
indirectly, and whether immediately, incidentally or ultimately, (i) to purchase
or to carry margin stock or to extend credit to others for the purpose of
purchasing or carrying margin stock, or to refund indebtedness originally

characterized as true or untrue and (b) any information contained in documents

     SECTION 3.17. Binding Effect. This Agreement and each other Loan Document
to which it is a party constitute legal and valid obligations, binding upon it,
enforceable against it in accordance with their respective terms, except as

rights held by any other Person; no claim or litigation regarding any of the
foregoing is pending or, to its knowledge, threatened which is reasonably
expected to have a Material Adverse Effect.

modification to this Agreement, the Note and the other Loan Documents including,

the extent that they result from the gross negligence or willful misconduct of
the Bank or any Indemnified Party.

     (c) The provisions of this Section 8.03 shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of

demand therefor explaining in reasonable detail the nature of such claim and the

     SECTION 8.04. Applicable Law. This Agreement, the Note and the other Loan

be governed and construed by and interpreted in accordance with the internal
laws of the State of New York.

     SECTION 8.05. Waiver of Rights by the Bank; Waiver of Jury Trial, etc. (a)
Neither any failure nor any delay on the part of the Bank in exercising any
right, power or privilege hereunder or under any other Loan Documents shall
operate as a waiver thereof, nor shall a single or partial exercise thereof
preclude any other or further exercise of any other right, power or privilege.
Except as prohibited by law, each party hereto hereby waives any right it may
have to claim or recover in any litigation referred to in this Section any
special, exemplary, punitive or consequential damages or any damages other than,
or in addition to, actual damages. Each party hereto (i) certifies that no
representative, agent or attorney of the Bank has represented, expressly or
otherwise, that the Bank would not, in the event of litigation, seek to enforce
the foregoing waivers and (ii) acknowledges that it has been induced to enter
into this Agreement and/or the Loan Documents to which it is a party by, among
other things, the mutual waivers and certifications herein.

     (b) EACH OF THE BORROWER, EACH GUARANTOR AND THE BANK HEREBY IRREVOCABLY
AND UNCONDITIONALLY WAIVES, AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS
PLAINTIFF, DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN
RESPECT OF ANY ISSUE, CLAIM OR ACTION IN ANY WAY, INVOLVING OR ARISING, DIRECTLY
OR INDIRECTLY, OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.

     SECTION 8.06. Acknowledgments. Each of the Borrower and each Guarantor
hereby acknowledges that:

          (a) it has been advised by counsel in the negotiation, execution and
     delivery of this Agreement, the Note and the other Loan Documents to which
     it is a party;

          (b) the Bank does not have any fiduciary relationship with it and the
     relationship between the Bank, on one hand, and the Borrower, on the other
     hand, is solely that of debtor and creditor; and

          (c) no joint venture exists among the Borrower, the Guarantors and the
     Bank.

     SECTION 8.07. Consent to Jurisdiction. (a) Each of the Borrower and each
Guarantor hereby irrevocably submits to the non-exclusive jurisdiction of any
United States Federal or New York State court sitting in New York City in any
action or proceedings arising out of or relating to any Loan Documents and
hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in any such court and irrevocably waives
any objection it may now or hereafter have as to the venue of any such action or
proceeding brought in such a court or the fact that such court is an
inconvenient forum.

     (b) Each of the Borrower and each Guarantor irrevocably and unconditionally
consents to the service or process in any such action or proceeding in any of
the aforesaid courts by the mailing of copies of such process to them by
certified or registered mail at its address specified in Subsection 8.01.

     SECTION 8.08. Extension of Maturity. Except as otherwise expressly provided
herein, whenever a payment to be made hereunder shall fall due and payable on
any day other than a Business Day, such payment may be made on the next
succeeding Business Day, and such extension of time shall be included in
computing interest.

     SECTION 8.09. Modification of Agreement. No modification, amendment or
waiver of any provision of this Agreement, the Note or any other Loan Document,
nor consent to any departure by the Borrower, any Guarantor or any of their
respective Subsidiaries therefrom shall in any event be effective unless the
same shall be in writing and signed by the Bank, the Borrower and each other
party to be charged and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. No notice to or
demand on the Borrower, the Guarantors or any of their respective Subsidiaries
in any case shall entitle the Borrower, the Guarantors or any of their
respective Subsidiaries, as the case may be, to any other or further notice or
demand in the same, similar or other circumstance.

                                      -44-

     SECTION 8.10. Participations and Assignments. (a) Neither the Borrower nor
the Guarantors may assign or transfer any of their interests under this
Agreement, the Note or any other Loan Documents without the prior written
consent of the Bank.

     (b) The Bank reserves the right to grant participations in or to sell and
assign its rights, duties or obligations with respect to the Loans or the
Commitment to such banks or other institutional lenders as it may choose,
including, without limitation, any Federal Reserve Bank in accordance with
applicable law and without the consent of the Borrower or the Guarantors, which
consent is deemed to be granted.

     SECTION 8.11. Reinstatement; Certain Payments. If claim is ever made upon
the Bank for repayment or recovery of any amount or amounts received by the Bank
in payment or on account of any of the obligations under this Agreement, the
Bank shall give prompt notice of such claim to the Borrower, and if the Bank
repays all or part of said amount by reason of (a) any judgment, decree or order
of any court or administrative body having jurisdiction over the Bank or any of
its property, or (b) any settlement or compromise of any such claim effected by
the Bank with any such claimant, then and in such event each of the Borrower and
each Guarantor agrees that any such judgment, decree, order, settlement or
compromise shall be binding upon it notwithstanding the cancellation of the
Note, any Guaranty or any other instrument evidencing the obligations under this
Agreement or the Guaranties or the termination of this Agreement, and each of
the Borrower and each Guarantor shall be and remain liable to the Bank hereunder
for the amount so repaid or recovered to the same extent as if such amount had
never originally been received by the Bank.

     SECTION 8.12. Right of Setoff. In addition to any rights and remedies of
the Bank provided by law, the Bank and each of its Affiliates, including without
limitation Chase Securities, Inc., is hereby authorized at any time and from
time to time, without prior notice to the Borrower or any Guarantor (any such
notice being expressly waived by the Borrower and the Guarantors) to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Bank or any Affiliate of the Bank to or
for the credit or the account of the Borrower or any Guarantor against any and
all the obligations of the Borrower (including its obligations as guarantor) or
any Guarantor now or hereafter existing under this Agreement, the Note, and any
of the other Loan Documents to which such Person is a party and pursuant to
which such Person is obligated to the Bank, irrespective of whether or not the
Bank shall have made any demand under such Loan Document and although such
obligations may be in any currency, direct or indirect, absolute or contingent,
matured or unmatured. The Bank agrees to promptly notify the Borrower or the
appropriate Guarantor after any such setoff and application made by the Bank or
such Affiliate, but the failure to give such notice shall not affect the
validity of such setoff and application. The rights of the Bank under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of setoff) which the Bank may have.
