     SECTION 2. LOANS.
                ------

     2.1  Revolving Loans.
          --------------- 

     2.1.1 Upon the terms and subject to the conditions of this Agreement,
and in reliance upon the representations, warranties and covenants of the
Borrower made herein, the Lender agrees to make loans ("Revolving Loans") to the
Borrower, at the Borrower's request from time to time, from and after the date
hereof and prior to the Maturity Date, provided that the principal amount of
                                       --------                             
Revolving Loans outstanding at any time shall not exceed the lesser of (i) the
Revolving Credit Maximum Amount and (ii) the Borrowing Base at such time, and
                                                                             
provided, further, that at the time the Borrower requests a Revolving Loan and
--------  -------                                                             
after giving effect to the making thereof there has not occurred and is not
continuing any Default or Event of Default.  The Borrower agrees that it shall
be an Event of Default if at any time the Revolving Loans outstanding shall
exceed the lesser of (i) the Revolving Credit Maximum Amount and (ii) the
Borrowing Base at such time, unless the Borrower shall, upon notice of such
excess from the Lender, promptly pay cash to the Lender to be credited to the
Loan Account in such amount as shall be necessary to eliminate the excess.  All
requests for Revolving Loans shall be in such form and shall be made in such
manner as shall be agreed between the Borrower and the Lender in accordance with
the Lender's customary practices.  The Revolving Loans shall be evidenced by a
Revolving Credit Note (the "Revolving Credit Note") substantially in the form of
                                                                                
Exhibit A-1 hereto.
-----------        

     2.1.2  The Borrower may prepay outstanding Revolving Loans and the
Revolving Credit Note in whole or in part at any time without premium or
penalty, except as otherwise provided in Section 2.3.5.  Amounts so paid in
respect of the Revolving Loans and the Revolving Credit Note and other amounts
may be borrowed and reborrowed from time to time as provided in Section 2.1.1.
On the Maturity Date, the Borrower shall repay all outstanding Revolving Loans
and the Revolving Credit Note, together with all unpaid interest thereon and all
fees and other amounts due hereunder.

     2.2  The Term Loan.
          ------------- 

     2.2.1  Upon the terms and subject to the conditions of this Agreement, and
in reliance upon the representations, warranties and covenants of the Borrower
made herein, the Lender agrees to lend to the Borrower, on a joint and several
basis, the sum of $2,600,000 on the date hereof (the "Term Loan") to be
evidenced by a Term Note (the "Term Note") substantially in the form of Exhibit
                                                                        -------
A-2 attached hereto.
---                 

     2.2.2  The principal of the Term Loan shall be payable in thirty-six
installments, with each of the first thirty-five such payments to be in the
amount of $43,333.33 and to be payable on the first day of each month (or the
first Business Day thereafter, if such day is not a Business Day) commencing on
August 1, 1996, and with the last of such thirty-six payments to be in the
amount of $1,083,333.45 and to be payable, along with any additional unpaid
principal of the Term Loan and all unpaid interest thereon, on the Maturity
Date.

     2.2.3  The Borrower may prepay the Term Loan and the Term Note in whole or
in part, without premium or penalty, except as otherwise provided in Section
2.3.5, at any time and from time to time upon five (5) days' prior written
notice to the Lender.  The principal amount of the Term Loan so prepaid shall be
at least $100,000 (unless the principal amount of the Term Loan shall be less
than  $100,000, in which event the prepayment may be equal to such unpaid
principal amount) or a multiple of $100,000, in excess of $100,000, provided
                                                                    --------
that the Borrower shall also pay accrued interest on the principal so prepaid to
the date of such prepayment and all fees and charges payable on or before the
date of such prepayment.  Prepayments shall be applied against unpaid
installments of principal of the Term Loan in inverse order of maturity of such
installments.  The Borrower shall not be permitted to reborrow any part of the
principal of the Term Loan so prepaid at any time or under any circumstances.

     2.3  Interest, Fees and Prepayment.
          ----------------------------- 

     2.3.1  Revolving Loans shall bear interest at a rate per annum equal to
3/4% above the Base Rate in effect from time to time; and the Term Loan shall
bear interest at a rate per annum equal to 1% above the Base Rate in effect from
time to time; provided that if an Event of Default shall occur, then at the
              --------                                                     
option of the Lender the unpaid balance of the Loans shall bear interest, to the
extent permitted by law, compounded monthly at an interest rate equal to 3%
above the Base Rate in effect on the day such Event of Default occurs, until
such Event of Default is cured or waived.  Interest on Loans (not at the time
overdue) shall be payable monthly in arrears on the first Business Day of each
month commencing with August 1, 1996.  Any change in the Base Rate shall result
in a change on the same day in the rate of interest to accrue from and after
such day on the unpaid balance of principal of the Loans.

     2.3.2.  The Borrower shall pay to the Lender any and all reasonable charges
customarily made by the Lender against Borrower.

     2.3.3  The Borrower authorizes the Lender to charge to any deposit or other
account which the Borrower may maintain with the Lender the interest, fees,
charges, taxes and 

                                      -11-
<PAGE>
 
expenses provided for in this Agreement or any other document executed or
delivered in connection herewith, and upon making any such change to such
account, the Lender shall notify the Borrower thereof in accordance with its
customary practices.

     2.3.4  If, after the date hereof, the Lender shall have determined that the
adoption of any applicable law, rule, regulation, guideline, directive or
request (whether or not having the force of law) regarding capital requirements
for banks or bank holding companies, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Lender with any of the foregoing imposes or
increases a requirement by the Lender to allocate capital resources to the
Lender's commitment to make Loans hereunder which has or would have the effect
of reducing the return on the Lender's capital to a level below that which the
Lender could have achieved (taking into consideration the Lender's then existing
policies with respect to capital adequacy and assuming full utilization of the
Lender's capital) but for such adoption, change or compliance by any amount
deemed by the Lender to be material, then:  (i) the Lender shall promptly after
its determination of such occurrence give notice thereof to the Borrower; and
(ii) to the extent that the costs of such increased capital requirements are not
reflected in the Base Rate, the Borrower and the Lender shall thereafter attempt
to negotiate in good faith, within 30 days following the date the Borrower
receive such notice, an adjustment payable hereunder that will adequately
compensate the Lender in light of the circumstances.  If the Lender and the
Borrower are unable to agree to such adjustment within 30 days following the
date upon which the Borrower receive such notice, then commencing on the date of
such notice (but no earlier than the effective date of any such increased
capital requirement), the fees payable hereunder shall increase by an amount
that will, in the Lender's reasonable determination, provide adequate
compensation.

     2.3.5  In the event that all of the Loans are prepaid in whole or in part
prior to the Maturity Date pursuant to Sections 2.1.2 or 2.2.3, respectively,
the Borrower shall pay to the Lender a prepayment fee equal to that percentage
of the amount of the outstanding Loans so prepaid which is set forth below:

to the Lender on the first Business Day of each fiscal quarter of the Borrower,
commencing September 30, 1996, a commitment fee equal to one-quarter of one
percent (1/4%) per annum of the Average Unused Amount during the preceding
quarter, such commitment fee to be payable quarterly in arrears.


     SECTION 3.  REPRESENTATIONS AND WARRANTIES.
                 ------------------------------ 

     The Borrower hereby warrants and covenants as follows:

     3.1  Organization and Qualification.  The Borrower (i) is a corporation
          ------------------------------                                    
duly organized, validly existing and in good standing under the laws of the
State of Delaware, (ii) has all requisite corporate power and authority to own
its property and conduct its business as now conducted and as presently
contemplated; and (iii) except as set forth in Exhibit B, is duly qualified and
                                               ---------                       
in good standing in each jurisdiction (which jurisdictions are listed on 
Exhibit B hereto) where the nature of its properties or its business (present or
------- -                                                                       
proposed) requires such qualification, except where the failure to so qualify is
not likely to have a material adverse effect on the condition (financial or
otherwise), properties, business or prospects of the Borrower.  Since the date
of the Initial Financial Statement, the Borrower has continued to engage in
substantially the same business as that in which it was then engaged and is
engaged in no unrelated business.

     3.2  Corporate Authority; Valid Obligations; Approvals.  The execution,
          -------------------------------------------------                 
delivery and performance of the Loan Documents and the transactions and other
documents contemplated hereby and thereby are within the Borrower's corporate
authority, have been authorized by all 

                                      -13-
<PAGE>
 
necessary corporate proceedings on the part of the Borrower, and do not and will
not contravene any provision of law, its charter documents or its by-laws, or
contravene any provisions of, or constitute a Default or Event of Default
hereunder or a default under any other agreement, instrument, judgment, order,
decree, permit, license or undertaking binding upon or applicable to the
Borrower or any of its properties, or result in the creation, other than in
favor of the Lender, of any mortgage, pledge, security interest, lien,
encumbrance or charge upon any of the properties or assets of the Borrower. The
Loan Documents have been duly executed and delivered and constitute the legal,
valid and binding obligations of the Borrower enforceable in accordance with
their terms. The execution, delivery and performance of the Loan Documents and
the transactions and other documents contemplated hereby and thereby do not
require any approval or consent of, or filing or registration with, any person,
except filings under the Uniform Commercial Code in connection with the
Collateral consisting of personalty and fixtures.

     3.3  Title to Properties; Absence of Liens. The Borrower has good and
          -------------------------------------                           
marketable title to all of its properties, assets and rights of every name and
nature now purported to be owned by it, which properties, assets and rights
include all those necessary to permit the Borrower to conduct its business as
such business was conducted on the date of the Initial Financial Statement
(including, without limitation, all patents, copyrights, trademarks, tradenames
and service marks necessary for the conduct of its business), free from all
liens, charges and encumbrances whatsoever except for insubstantial and
immaterial defects in title and liens, charges or encumbrances permitted under
Section 5.6.  All such properties, assets and rights, and to the best of the
Borrower's knowledge, all properties which are material to the business of the
Borrower which are leaseholds, are free and clear of all title defects or
objections, liens, claims, charges, security interests and other Encumbrances of
any nature whatsoever, and are not, in the case of real property, subject to any
rights of way, building, use or other restrictions, easements, exceptions,
variances, reservations or limitations of any nature whatsoever except, with
respect to all such properties and assets, (i) provisions of existing building
and zoning laws, (ii) liens for current taxes not yet due, and (iii)
Encumbrances permitted under Section 5.6.

     3.4  Location of Records and Collateral; Name Change.  The Borrower shall
          -----------------------------------------------                     
give the Lender written notice of each location at which Collateral is or will
be kept and each office of the Borrower at which the records of the Borrower
pertaining to Accounts Receivable and contract rights are kept. All Collateral
owned by the Borrower is and shall be kept at such locations as appear on
                                                                         
Exhibit B hereto, and all records of the Borrower pertaining to Accounts and
---------                                                                   
contract rights are and shall be kept at the location set forth therefor on
                                                                           
Exhibit B (or, in each case, as appears in a notice delivered pursuant to the
---------                                                                    
previous sentence).  The Borrower shall give the Lender 30 days' prior written
notice of any change in its name or corporate form or any change in the name or
names under which the Borrower's business is transacted.

     3.5  Compliance.  The Borrower (i) has all necessary permits, approvals,
          ----------                                                         
authorizations, consents, licenses, franchises, registrations and other rights
and privileges (including without limitation patents, trademarks, trade names
and copyrights) to allow it to own and operate its business without any
violation of law or the rights of others, (ii) is duly authorized, qualified and
licensed under and in compliance with all applicable laws, regulations,
authorizations and orders 

                                      -14-
<PAGE>
 
of public authorities (including, without limitation, Environmental Laws and
laws relating to ERISA or to employee benefit plans generally), and (iii) has
performed all obligations required to be performed by it under, and is not in
default under or in violation of, its certificate of incorporation or other
charter documents, or any agreement, lease, mortgage, note, bond, indenture,
license or other instrument or undertaking to which it is a party or by which
any of it or any of its properties are bound, and the Borrower has not received
any notice by any governmental authority or third party with respect to the
generation, storage, or disposal or release or threat of release of Hazardous
Materials, or with respect to any violation of any Environmental Laws. The
Borrower and each Affiliate has fulfilled its obligations under the minimum
funding standards of ERISA and the Code with respect to each Plan and is in
compliance in all material respects with the applicable provisions of ERISA and
the Code, and has not incurred any liability to the Pension Benefit Guaranty
Corporation or a Plan under Title IV of ERISA, and no "prohibited transaction"
or "reportable event" (as such terms are defined in ERISA) has occurred with
respect to any Plan.

     3.6  Financial Statements.  The Borrower has furnished to the Lender its
          --------------------                                               
audited balance sheet as of December 31, 1995 and the related statements of
earnings and retained earnings and cash flows for the year then ended, which
were prepared in accordance with GAAP, certified by independent certified public
accountants acceptable to the Lender and fairly present the financial position
of the Borrower as at the close of business on such date and the results of its
operations for the year then ended.  The Borrower has also furnished to the
Lender its unaudited balance sheet and statement of income as at March 31, 1996
and for the three month period then ended (the "Initial Financial Statement"),
which was prepared in accordance with GAAP certified by the chief financial
officer of the Borrower and fairly presents the financial position of the
Borrower as at the close of business on such date and the results of its
operations for the three month period then ended, subject to normal year-end
audit adjustments, none of which will be materially adverse.  At the date
hereof, the Borrower has no Indebtedness or other liabilities, whether accrued,
absolute, contingent or otherwise, and whether due or to become due, that are
not set forth on the Initial Financial Statement.  Since the Initial Financial
Statement there have been no material adverse changes, individually or in the
aggregate, in the business, condition (financial or otherwise), results of
operations, assets or liabilities of the Borrower.

     3.7  Events of Default.  As of the date of this Agreement, no Default or
          -----------------                                                  
Event of Default exists.

     3.8  Taxes.  The Borrower has filed all federal, state and other tax
          -----                                                          
returns required to be filed for all Taxes, and has fully paid (or has
established adequate reserves in accordance with GAAP for the payment of) all
Taxes, assessments and other such governmental charges due from the Borrower.
The Borrower has not executed any waiver that would have the effect of extending
the applicable statute of limitations in respect of any Tax.

     3.9  Labor Relations; Litigation.  The Borrower is not engaged in any
          ---------------------------                                     
unfair labor practice and there is no litigation, proceeding, governmental
investigation (administrative or judicial) or labor dispute or complaint,
pending or, to the best knowledge of the Borrower, threatened against the
Borrower, which, if decided adversely to the Borrower, could have a 

                                      -15-
<PAGE>
 
materially adverse effect on the business, condition (financial or otherwise),
results of operations or assets of the Borrower or on the ability of the
Borrower to perform its obligations under the Security Documents or under any
other agreement or document contemplated hereby or thereby, nor to its knowledge
is any substantial basis for any such litigation or labor dispute known to
exist.

     3.10  Environmental Matters.
           --------------------- 

     (a)    The Borrower has obtained all permits, licenses and other
authorizations which are required under all Environmental Laws.  The Borrower is
in compliance with the terms and conditions of all such permits, licenses and
authorizations, and is also in compliance with all other limitations,
restrictions, conditions, standards, prohibitions, requirements, obligations,
schedules and timetables contained in any applicable Environmental Law or in any
regulation, code, plan, order, decree, judgment, injunction, notice or demand
letter issued, entered, promulgated or approved thereunder.

     (b)    No notice, notification, demand, request for information, citation,
summons or order has been issued, no complaint has been filed, no penalty has

Environmental Laws on any of the real property or properties owned, leased or
used by the Borrower, and no governmental actions have been taken or, to the

Hazardous Materials at any property owned by it in any deed to such property.

     (e)    Neither the Borrower nor, to the best knowledge of the Borrower, any
previous owner, tenant, occupant or user of any property owned, leased or used
by the Borrower, has (i) engaged in or permitted any operations or activities
upon or any use or occupancy of such property, or any portion thereof, for the
purpose of or in any way involving the handling, manufacture,

used in day-to-day operations of such property in connection with the Borrower's
business thereon and in such case, only in compliance with all Environmental
Laws, or (ii) transported any Hazardous Materials to, from or across such
property except to the extent commonly used in day-to-day operations of such

corporate restriction which will, under current or foreseeable conditions,
materially and adversely affect its business, condition (financial or
otherwise), results of operations or assets.

     3.12  Contracts with Affiliates, Etc.  Except for agreements or
           ------------------------------                           
transactions (in each case) in the ordinary course of business and on an arm's-
length basis, the Borrower is not a party to or otherwise bound by any
agreements, instruments or contracts (whether written or oral) with any
Affiliate.

which materially adversely affects, or which would in the future materially
adversely affect, the business, condition (financial or otherwise), results of
operations or assets of the Borrower.

first out" basis, the Borrower (i) will not be left with unreasonably small
capital with which to engage in its business, even allowing for reasonable
margins for error in the projections of the Borrower's future performance (ii)
will not have incurred Indebtedness beyond its ability to pay such Indebtedness
as it matures, and (iii) will have assets (both tangible and intangible) having
a present fair salable value in excess of the amount required to pay the
probable liability on its then existing debts (whether matured or unmatured,
liquidated or unliquidated, absolute fixed or contingent).

charge.  The provisions of this Section 5.4 shall be deemed to be supplemental
to, but not duplicative of the provisions of any of the Security Documents that
require payment of Taxes.

   5.5  Limitation of Indebtedness.  Except with the prior written consent of

permitted by Section 5.14 and subject to the limitations set forth in Section
5.6; (iv) Indebtedness for Taxes or other charges, subject, however, to the
limitations set forth in Section 5.4; and (v) Indebtedness on open account for
the purchase price of services, materials and supplies incurred by the Borrower
in the ordinary course of business (not as a result of borrowing), so long as
all of such open account Indebtedness shall be promptly paid and discharged when
due or in conformity with customary trade terms and practices, except for any
such open account Indebtedness which is being 

                                      -22-
<PAGE>
 
contested in good faith by the Borrower and as to which adequate reserves have
been established and are being maintained in accordance with GAAP and as to
which no Encumbrance has been placed on any property of the Borrower.

Lender; (iii) Encumbrances securing Indebtedness for the purchase price of
capital assets (including rights of lessors under capital leases) to the extent
such Indebtedness is permitted by Section 5.5(iii), provided that (a) each such

Encumbrance is given solely to secure the purchase price of, or the lease
obligations under, such property, does not extend to any other property of the
Borrower and is given at the time of acquisition of such property, and (b) the
Indebtedness secured thereby does not exceed the lesser of the cost of such
property or its fair market value at the time of acquisition; (iv) liens for
taxes, fees, assessments and other governmental charges to the extent that

not at the time required and such liens do not, individually or in the
aggregate, materially detract from the value or limit the use of any property
subject thereto.

        -------------------------------------------------------
