payable to the order of such Lender and representing the obligation of the
Borrower to pay the amount of the Loan made by such Lender. Each Lender is
hereby authorized to record the date, and amount of its Loan and the date and
amount of each payment or prepayment of principal thereof, on the schedule
annexed to and constituting a part of its Note, and any such recordation shall
constitute prima facie evidence of the accuracy of the information so recorded;
           ----- -----
provided, that the failure of such Lender to make any such recordation shall not
--------
impair or otherwise affect the validity or enforceability of its Note. Each Note

the Borrower the aggregate of the amounts made available to the Agent by the
Lenders, by wire transfer and in like funds as received by the Agent, to such
account of the Borrower as may be specified by the Borrower in writing to the
Agent.

          2.4  Interest Rates and Payment Dates.  (a) Each Loan shall bear
               --------------------------------

nonusurious interest rate permitted by applicable law .

          (b)  If all or a portion of (i) any principal of any Loan, (ii) any

be paid when due (whether at the stated maturity, by acceleration or otherwise),

bear interest at 13% per annum from the date of such non-payment until such
overdue principal, interest, commitment fee or other amount is paid in full (as
well after as before judgment), but in no event in excess of the maximum
nonusurious interest rate permitted by applicable law.

          (c)  Interest shall be payable in arrears on each Interest Payment
Date, provided that interest accruing pursuant to paragraph (b) of this Section
      --------                                                                 
shall be payable from time to time on demand.

          2.5  Optional Prepayments.  The Borrower may at any time and from time
               --------------------
to time prepay the Loans, in whole or in part, without premium or penalty, upon
at least four Business Days' irrevocable notice to the Agent, specifying the
date and amount of prepayment. Upon receipt of any such notice the Agent shall
promptly notify each Lender thereof. If any such notice is given, the amount
specified in such notice shall be due and payable on the date specified therein,
together with accrued interest to such date on the amount prepaid. Amounts
prepaid on account of the Loans may not be reborrowed. Partial prepayments
pursuant to this Section shall be in an aggregate principal amount of $100,000
or a whole multiple thereof.

          2.6  Mandatory Prepayments.  Unless the Required Lenders otherwise

agree, the Borrower shall prepay the Loans and reduce the Commitments in an
amount equal to 100% of the Net Proceeds of any sale, lease, assignment,
exchange or other disposition for cash of any asset or group of assets
(including, without limitation, insurance proceeds paid as a result of any
destruction, casualty or taking of any property of the Borrower or any
Subsidiary), not made in the ordinary course of business, by the Borrower or any
Subsidiary of the Borrower, in any such case no later than three Business Days
following receipt by the Borrower or such Subsidiary of such proceeds, together
with accrued interest to such date on the amount prepaid. Prepayments of Loans
may not be reborrowed. Nothing in this Section 2.6 shall be construed to
derogate any restriction or limitation contained in any Loan Document imposed on
any transaction of the types described in this Section 2.6, including without
limitation the restrictions set forth in Sections 6.5 and 6.6 hereof.

          2.7  Computation of Interest and Fees.  (a) Interest shall be

<PAGE>
 
          2.8  Pro Rata Treatment and Payments.  (a)  Each borrowing by the
               -------------------------------   
Borrower from the Lenders hereunder, and any reduction of the Commitments of the
Lenders shall be made pro rata according to the respective Commitment
Percentages of the Lenders. Each payment (including each prepayment) by the
Borrower on account of principal of and interest on the Loans shall be made pro
rata according to the respective outstanding principal amounts of the Loans then
held by the Lenders. All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without set-off or counterclaim and shall be made prior
to 12:00 noon, New York City time, on the due date thereof to the Agent, for the
account of the Lenders, at the Agent's office in New York, New York, and to the
Agent's account specified in Section 10.2, in Dollars and in immediately
available funds. The Agent shall distribute such payments to the Lenders
promptly upon receipt in like funds as received. If any payment hereunder
becomes due and payable on a day other than a Business Day, such payment shall
be extended to the next succeeding Business Day, and, with respect to payments
of principal, interest thereon shall be payable at the then applicable rate
during such extension.

          (b)  Unless the Agent shall have been notified in writing by any
Lender prior to a borrowing that such Lender will not make the amount that would
constitute its Commitment Percentage of such borrowing available to the Agent,
the Agent may assume that such Lender is making such amount available to the
Agent, and the Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Agent, on demand, such amount with interest thereon at a rate equal to
the daily average Federal Funds Effective Rate for the period until such Lender
makes such amount immediately available to the Agent. A certificate of the Agent
submitted to any Lender with respect to any amounts owing under this Section
shall be conclusive in the absence of manifest error. If such Lender's
Commitment Percentage of such borrowing is not made available to the Agent by
such Lender within three Business Days of such Borrowing Date, the Agent shall
also be entitled to recover such amount with interest thereon at 11% per annum
on demand, from the Borrower, but in no event or excess of the maximum
nonusurious interest rate permitted by the applicable law.

          2.9  Requirements of Law.
               --------------------  

          (a)  If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, the Borrower shall promptly pay to 

                                       13
<PAGE>
 
such Lender such additional amount or amounts as will compensate such Lender for
such reduction.

          (b)  If any Lender becomes entitled to claim any additional amounts
pursuant to this Section, it shall promptly notify the Borrower (with a copy to
the Agent) of the event by reason of which it has become so entitled.  A
certificate as to any additional amounts payable pursuant to this Section
submitted by such Lender to the Borrower (with a copy to the Agent) shall be
conclusive in the absence of manifest error.  The agreements in this Section
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

          2.10 Taxes.  (a)  All payments made by the Borrower under this
               -----
Agreement and any Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Agent or any Lender as a result of a
present or former connection between the Agent or such Lender and the
jurisdiction of the Governmental Authority imposing such tax or any political
subdivision or taxing authority thereof or therein (other than any such
connection arising solely from the Agent or such Lender having executed,
delivered or performed its obligations or received a payment under, or enforced,
this Agreement or any Note). If any such non-excluded taxes, levies, imposts,
duties, charges, fees deductions or withholdings ("Non-Excluded Taxes") are
                                                   ------------------
required to be withheld from any amounts payable to the Agent or any Lender
hereunder or under any Note, the amounts so payable to the Agent or such Lender
shall be increased to the extent necessary to yield to the Agent or such Lender
(after payment of all Non-Excluded Taxes) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Agreement,
provided, however, that the Borrower shall not be required to increase any such
--------  -------
amounts payable to any Lender that is not organized under the laws of the United
States of America or a state thereof if such Lender fails to comply with the
requirements of clause (b) of this Section. Whenever any Non-Excluded Taxes are
payable by the Borrower, as promptly as possible thereafter the Borrower shall
send to the Agent for its own account or for the account of such Lender, as the
case may be, a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded
Taxes when due to the appropriate taxing authority or fails to remit to the
Agent the required receipts or other required documentary evidence, the Borrower
shall indemnify the Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Agent or any Lender as a result of any
such failure. The agreements in this Section shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

          
          (b)  Each Lender that is not incorporated under the laws of the United
States of America or a state thereof shall:

                                       14

          (i) (A) if such Lender is a "bank" within the meaning of Section
     881(c)(3)(A) of the Code, deliver to the Borrower and the Agent (x) two
     duly completed copies of United States Internal Revenue Service Form 1001
     or 4224, or successor applicable form, as the case may be, and (y) an
     Internal Revenue Service Form W-8 or W-9, or successor applicable form, as
     the case may be, or (B) if such Lender is not a "bank" within the meaning
     of Section 881(c)(3)(A) of the Code and cannot deliver either Internal
     Revenue Service Form 1001 or 4224, deliver (x) a certificate substantially
     in the form of Exhibit G (a "Non-Bank Status Certificate") and (y) two
                                  ---------------------------              
     completed and signed copies of Internal Revenue Service Form W-8 or
     successor applicable form;

          (ii) deliver to the Borrower and the Agent two further copies of any
     such form or certification on or before the date that any such form or
     certification expires or becomes obsolete and after the occurrence of any
     event requiring a change in the most recent form previously delivered by it
     to the Borrower; and

         (iii) obtain such extensions of time for filing and complete such
     forms or certifications as may reasonably be requested by the Borrower or
     the Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Borrower and the Agent.
Such Lender shall certify (i) in the case of a Form 1001 or 4224, that it is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes, (ii) in the case of a
Non-Bank Status Certificate, that it is not a "bank" as such term is defined in
Section 881(c)(3)(A) of the Code, and (iii) in the case of a Form W-8 or W-9,
that it is entitled to an exemption from United States backup withholding tax.
Each Person that shall become a Lender or a Participant pursuant to Section 9.6
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms and statements required pursuant to this Section, provided that
                                                                   --------     
in the case of a Participant such Participant shall also furnish all such
required forms and statements to the Lender from which the related participation
shall have been purchased.

               -----------------------------------------                      
by any Lender shall be made and maintained at such Lender's Applicable Lending
Office.

          (b) Each Lender agrees that if it makes any demand for payment under
Section 2.10(a), or if any adoption or change of the type described in Section
2.9 shall occur with respect to it, it will use reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions and so long as
such efforts would not be disadvantageous to it, as determined in its sole
discretion) to designate a different lending office if the making of such a
designation would reduce or obviate the need for the Borrower to make payments
under Section 2.10(a), or would eliminate or reduce the effect of any adoption
or change described in Section 2.9.

          SECTION 3.    REPRESENTATIONS AND WARRANTIES

          To induce the Agent and the Lenders to enter into this Agreement and
to make the Loans, the Borrower hereby represents and warrants to the Agent and
each Lender that:

          3.1  Financial Condition.  (a) The consolidated balance sheet of the
               -------------------                                              
Borrower and its consolidated Subsidiaries as at December 31, 1997 and the
related consolidated statements of income and of cash flows for the fiscal year
ended on such date, reported on by Arthur Anderson LLP, copies of which have
heretofore been furnished to each Lender, present fairly the consolidated
financial condition of the Borrower and its consolidated Subsidiaries as at such
date, and the consolidated results of their operations and their consolidated
cash flows for the fiscal year then ended.  Except as set forth on Schedule
3.1(a), the unaudited consolidated balance sheet of the Borrower and its
consolidated Subsidiaries as at September 30, 1998 and the related unaudited
consolidated statements of income and of cash flows for the nine-month period
ended on such date, certified by a Responsible Officer, copies of which have
heretofore been furnished to each Lender, present fairly the consolidated
financial condition of the Borrower and its consolidated Subsidiaries as at such
date, and the consolidated results of their operations and their consolidated
cash flows for the nine-month period then ended (subject to normal year-end
audit adjustments and absence of footnotes).  All such financial statements,
including the related schedules and notes thereto, have been prepared in
accordance with GAAP applied consistently throughout the periods involved
(except as approved by such accountants or Responsible Officer, as the case may
be, and as disclosed therein).  Neither the Borrower nor any of its consolidated
Subsidiaries had, at the date of the most recent balance sheet referred to
above, any material Guarantee Obligation, contingent liability or liability for
taxes, or any long-term lease or unusual forward or long-term commitment,
including, without limitation, any interest rate or foreign currency swap or
exchange transaction or other financial derivative, which is not reflected in
the foregoing statements or in the notes thereto and is required to be disclosed
pursuant to GAAP.  Except as set forth on Schedule 3.1(b), during the period
from September 30, 1998 to and including the date hereof there has been no sale,
transfer or other disposition by the Borrower or any of its consolidated
Subsidiaries of any material part of its business or property and no purchase or
other acquisition of any business or property (including any Capital Stock of
any other Person) material in relation to the consolidated financial condition
of the Borrower and its consolidated Subsidiaries at September 30, 1998.

          (b)  The operating forecast and cash flow projections of the Borrower
and its consolidated Subsidiaries, copies of which have heretofore been
furnished to the Lenders, have been prepared in good faith under the direction
of a Responsible Officer of the Borrower, and in accordance with GAAP except
that such forecast and projections do not include footnotes and other
disclosures which may be required pursuant to GAAP.  The Borrower has no reason
to believe that as of the date of delivery thereof such operating forecast and
cash flow projections are materially incorrect or misleading in any material
respect, or omit to state any material fact which would render them misleading
in any material respect.

          3.2  No Change.  (a) Except as set forth on Schedule 3.2, Since
               ---------                                                   
September 30, 1998 there has been no development or event which has had or could
have a Material Adverse Effect, and (b) during the period from September 30,
1998 to and including the date hereof no dividends or other distributions have
been declared, paid or made upon the Capital Stock of the Borrower nor has any
of the Capital Stock of the Borrower been redeemed, retired, purchased or
otherwise acquired for value by the Borrower or any of its Subsidiaries.

          3.3  Existence; Compliance with Law.  Except as set forth on
               ------------------------------                           
Schedule 3.3, each of the Borrower and its Subsidiaries (a) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, (b) has the corporate power and authority, and the legal right, to
own and operate its property, to lease the property it operates as lessee and to
conduct the business in which it is currently engaged, (c) is duly qualified as
a foreign corporation and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of property or the conduct of its
business requires such qualification and (d) is in compliance with all
Requirements of Law except to the extent that the failure to comply therewith
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect.

          3.4  Power; Authorization; Enforceable Obligations.  The Borrower
               ---------------------------------------------                 
has the corporate power and authority, and the legal right, to make, deliver and
perform the Loan Documents to which it is a party and to borrow hereunder and
has taken all necessary corporate action to authorize the borrowings on the
terms and conditions of this Agreement and any Notes and to authorize the
execution, delivery and performance of the Loan Documents to which it is a
party.  No consent or authorization of, filing with, notice to or other act by
or in respect of, any Governmental Authority or any other Person ("Approval") is
                                                                   --------     
required in connection with the borrowings hereunder or with the execution,
delivery, performance, validity or enforceability of the Loan Documents to which
the Borrower is a party other than Approvals which have been heretofore obtained
or made; it being understood, however, that the continued performance by the
Borrower and the other Loan Parties of their respective obligations under this
Agreement and the other Loan Documents after the date hereof will require
various Approvals, such as filings relating to environmental matters, ERISA
matters, tax matters, intellectual property filings, filings to maintain
corporate and similar standing and existence, filings pursuant to the Uniform
Commercial Code and other security filings and recordings, filings with the
Securities and Exchange Commission, Approvals necessary in connection with the
Split Rate Subordinated Notes and the Convertible PIK Preferred Stock, routine
filings in the ordinary course of business, and filings required in connection
with the exercise by the Agent and the Lenders of remedies in connection with
the Loan Documents.  This Agreement has been, and each other Loan Document to
which it is a party will be, duly executed and delivered on behalf of the
Borrower.  This Agreement constitutes, and each other Loan Document to which it
is a party when executed and delivered will constitute, a legal, valid and
binding obligation of the Borrower enforceable against the Borrower in
accordance with its terms, subject to the effects of bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and other similar laws
relating to or affecting creditors' rights 

                                       17
<PAGE>
 
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing.

          3.5  No Legal Bar.  Except as set forth on Schedule 3.7, the
               ------------                                             
execution, delivery and performance of the Loan Documents to which the Borrower
is a party, the borrowings hereunder and the use of the proceeds thereof will
not violate any Requirement of Law or Contractual Obligation of the Borrower or
of any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of its or their respective properties or revenues
pursuant to any such Requirement of Law or Contractual Obligation (other than
Liens created by the Security Documents in favor of the Agent).

          3.6  No Material Litigation.  Except as set forth on Schedule 3.6,
               ----------------------                                         
no litigation, investigation or proceeding of or before any arbitrator or
Governmental Authority is pending or, to the knowledge of the Borrower,
threatened by or against the Borrower or any of its Subsidiaries or against any
of its or their respective properties or revenues (a) with respect to any of the
Loan Documents or any of the transactions contemplated hereby or thereby, or (b)
which could have a Material Adverse Effect.

          3.7  No Default.  Except as set forth on Schedule 3.7, neither the
               ----------                                                     
Borrower nor any of its Subsidiaries is in default under or with respect to any
of its Contractual Obligations in any respect which could have a Material
Adverse Effect.  No Default or Event of Default has occurred and is continuing.

          3.8  Ownership of Property; Liens.    Each of the Borrower and its
               ----------------------------                                 
Subsidiaries has good record and indefeasible title in fee simple to, or a valid
leasehold interest in, all its real property, and good title to, or a valid
leasehold interest in, all its other property, and none of such property is
subject to any Lien except as permitted by Section 6.3.

          3.9  Intellectual Property.  The Borrower and each of its
               ---------------------                                 
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those which the failure to own or
license could not reasonably be expected to have a Material Adverse Effect (the
"Intellectual Property").  No claim has been asserted and is pending by any
 ---------------------                                                     
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property.  The use of
such Intellectual Property by the Borrower and its Subsidiaries does not
infringe on the rights of any Person, except for such claims and infringements
that, in the aggregate, could not reasonably be expected to have a Material
Adverse Effect.

          3.10  No Burdensome Legal Restriction.  No Requirement of Law of the
                --------------------------------                                
Borrower or any of its Subsidiaries could reasonably be expected to have a
Material Adverse Effect.

          3.11  Taxes.  Each of the Borrower and its Subsidiaries has filed or
                -----                                                          
caused to be filed all tax returns which, to the knowledge of the Borrower, are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made 

                                       18
<PAGE>
 
against it or any of its property and all other taxes, fees or other charges
imposed on it or any of its property by any Governmental Authority (other than
any the amount or validity of which are currently being contested in good faith
by appropriate proceedings and with respect to which reserves in conformity with
GAAP have been provided on the books of the Borrower or its Subsidiaries, as the
case may be); no tax Lien has been filed, and, to the knowledge of the Borrower,
no claim is being asserted, with respect to any such tax, fee or other charge.

          3.12 Federal Regulations.  No part of the proceeds of any Loans will
               -------------------                                             
be used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect, or for any purpose which violates, or which would be inconsistent
with, the provisions of the regulations of such Board of Governors.  If
requested by any Lender or the Agent, the Borrower will furnish to the Agent and
each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-3 or FR Form U-1 referred to in said Regulation U.

          3.13 ERISA.  Neither a Reportable Event nor an "accumulated funding
               -----                                                          
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  No termination of a Single Employer Plan has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such 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.  Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
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 and each Commonly Controlled Entity for post
retirement benefits to be provided to their current and former employees under
Plans which are welfare benefit plans (as defined in Section 3(1) of ERISA) does
not, in the aggregate, exceed to any material degree the assets under all such
Plans allocable to such benefits.

          3.14 Investment Company Act; Other Regulations.  The Borrower is not
               -----------------------------------------                       
an "investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.  The
Borrower is not subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board of Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness.

          3.15 Subsidiaries.  Schedule 3.15 sets forth the name of each direct
               ------------                                                    
or indirect Subsidiary of the Borrower, its form of organization, its
jurisdiction of organization, the total number of issued and outstanding shares
or other interests of Capital Stock thereof, the classes and number of issued
and outstanding shares or other interests of Capital Stock of each such class,
the name of each holder of Capital Stock thereof and the number of shares or
other interests of such Capital Stock held by each such holder and the
percentage of all outstanding shares or other interests of such class of Capital
Stock held by such holders.

          3.16 Security Documents.  (a)  The provisions of each Security
               ------------------                                        
Document are effective to create in favor of the Agent for the ratable benefit
of the Lenders a legal, valid and enforceable security interest in all right,
title and interest of the Loan Party party thereto in the "Collateral" described
therein.

          (b)  (i)  When financing statements have been filed in the offices in
the jurisdictions listed in Schedule 3.16, the Security Agreement shall
constitute a fully perfected first Lien (or, with respect to (x) the Shared
Collateral, second Lien subject only to the Lien created pursuant to HCFP Loan
Documents and (y) equipment and other property subject to Financing Leases,
second Lien subject only to the prior Liens created by such Financing Leases)
on, and security interest in, all right, title and interest of the Borrower in
the "Collateral" described therein, which can be perfected by such filing.

          (ii) When certificates representing the Pledged Stock (as defined in
the Pledge Agreement) are delivered to the Agent, together with stock powers
endorsed in blank by a duly authorized officer of the pledgors thereof (or, with
respect to the stock of HC Personnel Resources, Inc., and so long as
certificates representing that stock is in the possession of HCFP, upon the
execution and delivery of the Intercreditor Agreement), the Pledge Agreement
shall constitute a fully perfected first Lien (or with respect to the Shared
Collateral, second Lien subject only to the Lien created pursuant to the HCFP
Loan Documents) on, and security interest in, all right, title and interest of
the pledgors parties thereto in the "Collateral" described therein.

          (c)  Neither the Borrower nor any Subsidiary owns any property, or has
any interest in any property, that is not subject to a fully perfected first
priority Lien (or, with respect to (x) the Shared Collateral, second Lien
subject only to the Lien created pursuant to the HCFP Loan Documents and (y)
equipment and other property subject to Financing Leases, second Lien subject
only to the prior Liens created by such Financing Leases) on, or security
interest in, such property in favor of the Agent, other than any such property
having an aggregate fair market value at any one time not exceeding $250,000.

          3.17 Accuracy and Completeness of Information.  (a)  All factual
               ----------------------------------------                    
information, reports and other papers and data with respect to the Loan Parties
(other than projections) furnished, and all factual statements and
representations made, to the Agent or the Lenders by a Loan Party, or on behalf
of a Loan Party, were, at the time the same were so furnished or made, when
taken together with all such other factual information, reports and other papers
and data previously so furnished and all such other factual statements and
representations

                                       20
<PAGE>
 
previously so made, complete and correct in all material respects, to the extent
necessary to give the Agent and the Lenders true and accurate knowledge of the
subject matter thereof in all material respects, and did not, as of the date so
furnished or made, contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements contained
therein not misleading in light of the circumstances in which the same were
made.

          (b)  All projections with respect to the Loan Parties furnished by or
on behalf of a Loan Party to the Agent or the Lenders were prepared and
presented in good faith by or on behalf of such Loan Party.  No fact is known to
a Loan Party which materially and adversely affects or in the future is
reasonably likely (so far as such Loan Party can reasonably foresee) to have a
Material Adverse Effect which has not been set forth in the financial statements
referred to in Section 3.1 or in such information, reports, papers and data or
otherwise disclosed in writing to the Agent or the Lenders prior to the Closing
Date.

          3.18 Labor Relations.  No Loan Party is engaged in any unfair labor
               ---------------                                                
practice which could reasonably be expected to have a Material Adverse Effect.
There is (a) no unfair labor practice complaint pending or, to the best
knowledge of each Loan Party and each of the Subsidiaries, threatened against a
Loan Party before the National Labor Relations Board which could reasonably be
expected to have a Material Adverse Effect and no grievance or arbitration
proceeding arising out of or under a collective bargaining agreement is so
pending or threatened; (b) no strike, labor dispute, slowdown or stoppage
pending or, to the best knowledge of each Loan Party, threatened against a Loan
Party; and (c) no union representation question existing with respect to the
employees of a Loan Party and no union organizing activities are taking place
with respect to any thereof.

          3.19 Insurance.  Each Loan Party has, with respect to its properties
               ---------                                                       
and business, insurance covering the risks, in the amounts, with the deductible
or other retention amounts, and with the carriers, listed on Schedule 3.19,
which insurance meets the requirements of Section 5.5 hereof and Section 5(m) of
the Security Agreement as of the date hereof and the Closing Date.

          3.20 Solvency.  On the Closing Date, after giving effect on a pro
               --------                                                     
forma basis to the consummation of the Recapitalization and to the incurrence
and discharge of all indebtedness and obligations being incurred or discharged
on or prior to such date in connection herewith and therewith, (i) the amount of
the "present fair saleable value" of the assets of the Borrower and of the
Borrower and its Subsidiaries, taken as a whole, will, as of such date, exceed
the amount of all "liabilities of the Borrower and of the Borrower and its
Subsidiaries, taken as a whole, contingent or otherwise", as of such date, as
such quoted terms are determined in accordance with applicable federal and state
laws governing determinations of the insolvency of debtors, (ii) the present
fair saleable value of the assets of the Borrower and of the Borrower and its
Subsidiaries, taken as a whole, will, as of such date, be greater than the
amount that will be required to pay the liabilities of the Borrower and of the
Borrower and its Subsidiaries, taken as a whole, on their respective debts as
such debts become absolute and matured, (iii) neither the Borrower nor the
Borrower and its Subsidiaries, taken as a 

                                       21
<PAGE>
 
whole, will have, as of such date, an unreasonably small amount of capital with
which to conduct their respective businesses, and (iv) each of the Borrower and
the Borrower and its Subsidiaries, taken as a whole, will be able to pay their
respective debts as they mature. For purposes of this Section 3.20, "debt" means
"liability on a claim", "claim" means any (x) right to payment, whether or not
such a right is reduced to judgment, liquidated, unliquidated, fixed,
contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured
or unsecured, and (y) right to an equitable remedy for breach of performance if
such breach gives rise to a right to payment, whether or not such right to an
equitable remedy is reduced to judgment, fixed, contingent, matured or
unmatured, disputed, undisputed, secured or unsecured.

          3.21 Purpose of Loans.  The proceeds of the Loans shall be used by
               ----------------                                              
the Borrower for working capital purposes in the ordinary course of business.

          3.22 Environmental Matters.  Except as set forth on Schedule 3.22:
               ---------------------                                         

          (a)  The facilities and properties owned, leased or operated by the
Borrower or any of its Subsidiaries (the "Properties") do not contain, and have
                                          ----------                           
not previously contained, any Materials of Environmental Concern in amounts or
concentrations which (i) constitute or constituted a violation of, or (ii) could
give rise to liability under, any Environmental Law except in either case
insofar as such violation or liability, or any aggregation thereof, is not
reasonably likely to result in the payment of a Material Environmental Amount.

          (b)  The Properties and all operations at the Properties are in
compliance, and have in the last five years been in compliance, in all material
respects with all applicable Environmental Laws, and there is no contamination
at, under or about the Properties or violation of any Environmental Law with
respect to the Properties or the business operated by the Borrower or any of its
Subsidiaries (the "Business") which could materially interfere with the
                   --------                                            
continued operation of the Properties or materially impair the fair saleable
value thereof.

          (c)  Neither the Borrower nor any of its Subsidiaries has received any
notice of violation, alleged violation, non-compliance, liability or potential
liability regarding environmental matters or compliance with Environmental Laws
with regard to any of the Properties or the Business, nor does the Borrower have
knowledge or reason to believe that any such notice will be received or is being
threatened except insofar as such notice or threatened notice, or any
aggregation thereof, does not involve a matter or matters that is or are
reasonably likely to result in the payment of a Material Environmental Amount.

          (d)  Materials of Environmental Concern have not been transported or
disposed of from the Properties in violation of, or in a manner or to a location
which could give rise to liability under, any Environmental Law, nor have any
Materials of Environmental Concern been generated, treated, stored or disposed
of at, on or under any of the Properties in violation of, or in a manner that
could  give rise to liability under, any applicable Environmental Law except
insofar as any such violation or liability referred to in this paragraph, or any
aggregation thereof, is not reasonably likely to result in the payment of a
Material Environmental Amount.

          SECTION 8.    CONVERSION

          8.1  Conversion Right.
               ----------------   

          (a)  Subject to and upon compliance with the provisions of this
Section, each Lender shall have the right (the "Conversion Right"), at its
                                                ----------------          
option, upon (x) the occurrence of 

                                       40
<PAGE>
 
an Event of Default specified in Section 7(k), or (y) the Maturity Date, except
to the extent that the Loans have been previously prepaid, to convert the
principal amount of any such Loan, or any portion of such principal amount, into
that number of fully paid and non-assessable shares of Common Stock (as such
shares shall then be constituted) obtained by dividing the principal amount of
the Loans or portion thereof to be so converted by the Conversion Price in
effect at such time, by surrender of its Note in the manner provided in Section
8.2. A Lender is not entitled to any rights of a holder of shares of Common
Stock until such Lender has converted its Loan to shares of Common Stock, and
only to the extent such Loans are deemed to have been converted to shares of
Common Stock under this Section 8. If any amount paid or prepaid in respect of
any Loan is avoided, rescinded or must otherwise be restored or returned upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or any other Loan Party, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any other Loan Party or any substantial part of its property, or
otherwise, the Conversion Right with respect to such amount shall be reinstated
or shall continue to be effective, all as though such payments had not been
made.

          (b)  Common Stock issuable upon conversion of any Loan will bear
legends substantially in the form of those set forth on Schedule 8.1.

          (c)  The Borrower shall at all times reserve and keep available out of
its authorized Common Stock, solely for the purpose of issuance or delivery upon
conversion of the Loans, the number of shares of Common Stock that will be
required to be delivered in connection with such conversion pursuant to the
terms of the Indenture.

          (d)  If on the Closing Date or on the date the Conversion Price is
adjusted pursuant to the provisions of Sections 8.4 and 8.5, the Borrower shall
not have available sufficient authorized Common Stock for the purpose of
issuance or delivery upon conversion of the Loans, the Borrower shall, within
180 days from the Closing Date and/or any such date of adjustment, obtain such
additional authorized Common Stock for such purpose (the "Reservation Grace
                                                          -----------------
Period").  If any Reservation Grace Period shall have expired prior to the
------                                                                    
Borrower's obtaining additional authorized Common Stock sufficient to meet its
obligation under Section 8.1(c) (an "Authorization Default"), additional
                                     ---------------------              
interest ("Authorization Default Liquidated Damages") will accrue on the Loans
           ----------------------------------------                           
from and including the day following such Authorization Default to but excluding
the day on which such Authorization Default has been cured.  Authorization
Default Liquidated Damages will be paid monthly in arrears on each Interest
Payment Date, with the first such payment due on the first Interest Payment Date
following the date on which such Authorization Default Liquidated Damages begin
to accrue and will accrue at a rate per annum of one quarter of one percent
(0.25%) of the principal amount, to and including the 90th day following such
Authorization Default and at a rate per annum of one half of one percent (0.50%)
thereof from and after the 91st day following such Authorization Default.  In no
event will Authorization Default Liquidated Damages accrue at a rate per annum
exceeding one half of one percent (0.50%).

          8.2  Exercise of Conversion Right; Issuance of Shares of Common Stock
               ----------------------------------------------------------------
on Conversion.
-------------

          (a)  The Lenders have a Conversion Right which is exercisable in whole
or in part at any time and from time to time, subject to the limitations set
forth in Section 8.1(a).  In order to exercise its Conversion Right, a Lender
shall complete a notice in the then current form obtainable from the Agent and
in the form of Exhibit K (a "Conversion Notice") (which may be accompanied by a
                             -----------------                                 
share transfer form, or other instrument which may be required, signed by the
Lender or may include an authorization signed by the Lender, authorizing the
Lender's nominee to become the registered transferee and to execute any
requisite transfer form or other instrument which may be required, on behalf of
the Lender) and deliver such Conversion Notice and where appropriate, an
executed share transfer form, or other instrument which may be required, to the
Agent (together with the relevant Note) and any payment required by Section 8.6.
Once given, a Conversion Notice shall be irrevocable and may not be withdrawn
without the consent in writing of the Agent and, so long as no Default or Event
of Default has occurred and is continuing, the Borrower. The Agent shall deliver
to the Borrower promptly after receipt each Conversion Notice and each such
share transfer form or other instrument.

          (b)  The Conversion Right of any Lender in respect of a Loan being
prepaid pursuant to this Agreement and in respect of which the conditions
required for conversion have not been satisfied by the relevant Lender by the
end of the second Business Day prior to any date for prepayment thereof shall,
except as provided below, thereupon terminate. Notwithstanding the foregoing, if
there is a default in making full payment when due of the prepayment monies in
respect of any Loan, the Conversion Right in respect thereof shall extend up to
and including the date on which payment has been received by the relevant
Lender. The Conversion Right of a Lender in respect of a Loan becoming due and
payable as a result of the acceleration of the Loans following an Event of
Default shall terminate on the date that payment with respect to such Loan has
been received by such Lender.

          (c)  In the event that any Lenders have elected to convert their Loans
pursuant to this Section 8 by giving notice thereof to the Borrower in
accordance with the terms of this Agreement, then any subsequent prepayment of
the Loans shall not affect the right of such Lenders to receive shares of Common
Stock and such Loans of such Lenders shall not be so prepaid. No earlier than 60
days and no later than 30 days prior to the Maturity Date, the Borrower shall
deliver a notice to the Agent and the Lenders of the status of the Conversion
Rights, if any, of the Lenders.

          (d)  In order to exercise the Conversion Right with respect to any
Loan, the Lender shall surrender its Note, duly endorsed, at the office of the
Agent specified in Section 10.2 and shall give the Conversion Notice as
specified in Section 8.2(a). Such Conversion Notice shall state the portion of
the Loan of such Lender to be converted and the name or names (with address) in
which the certificate or certificates for shares of Common Stock which shall be
issuable on such conversion shall be issued, and shall be accompanied by
transfer taxes, if required pursuant to Section 8.7. The Agent shall promptly
notify the Borrower of 

                                       42
<PAGE>
 
such conversion and shall deliver such Note to the Borrower against delivery by
the Borrower to the Agent, for the account of the Lender converting such Loan or
portion thereof, of certificates for Common Stock receivable by such Lender upon
such conversion. Each such Note surrendered for conversion shall, unless the
shares of Common Stock issuable on conversion are to be issued in the same name
as the registration of such Note, be duly endorsed by, or be accompanied by
instruments of transfer in form satisfactory to the Agent and the Borrower duly
executed by the Lender or its duly authorized attorney.

          (e)  As promptly as practicable after satisfaction of the requirements
for conversion set forth above, subject to compliance with any restrictions on
transfer if shares of Common Stock issuable on conversion are to be issued in a
name other than that of the Lender (as if such transfer were a transfer of the
Note or Notes (or portion thereof) so converted), the Borrower shall issue and
shall deliver to the Agent, for the account of such Lender, at the office of the
Agent specified in Section 10.2, a certificate or certificates for the number of
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Section and a check or cash in
respect of any fractional interest in respect of a share Common Stock arising
upon such conversion, as provided in Section 8.3.  In case any Note shall be
surrendered for partial conversion, the Borrower shall execute and deliver to
Agent, for the account of such Lender, without charge to such Lender, a new Note
in an aggregate principal amount equal to the unconverted portion of the
surrendered Note.

          (f)  Each conversion shall be deemed to have been effected as to any
such Loan (or portion thereof) within 3 Business Days of the date on which the
requirements set forth above in this Section 8.2 have been satisfied as to such
Loan (or portion thereof), and the Person in whose name any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall become the holder of record of the shares represented thereby on such
conversion date; provided, however, that any such surrender on any date when the
                 --------                                                       
stock transfer books of the Borrower shall be closed shall constitute the Person
in whose name the certificates are to be issued as the record holder thereof for
all purposes on the next succeeding day on which such stock transfer books are
open, but such conversion shall be at the Conversion Price in effect on the date
upon which such Note shall be surrendered.

          (g)  Interest on the principal amount of any Loan or portion thereof
surrendered for conversion shall cease to accrue from and after the effective
date of such conversion.

          8.3  Cash Payment in Lieu of Fractional Shares.
               -----------------------------------------   

          No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Loans. If any fractional share of
stock otherwise would be issuable upon the conversion of any Loan or Loans, the
Borrower shall make an adjustment therefor in cash at the current market value
thereof to the Lenders of such Loans.  Upon exercise of its Conversion Right a
Lender shall, when delivering the relevant Conversion Notice or no later than 21
days following the relevant Conversion Date, give directions to the 

                                       43
<PAGE>
 
Agent for payment of any cash sum (rounded up to the nearest $0.01) which such
Lender is entitled to receive pursuant to this Section 8.3 and which shall be
paid by way of U.S. Dollar check drawn on a bank in the City of New York or, by
wire transfer to a U.S. Dollar account maintained by the Lender with a bank in
the City of New York.

          8.4  Conversion Price.
               ----------------   

          (a)  The initial conversion price of the Loans will be $2.379448 per
share of Common Stock (as adjusted in accordance with the terms of this
Agreement, from time to time, the "Conversion Price").
                                   ----------------   

          (b)  Upon receipt of a Conversion Notice from a Lender, the Borrower
shall promptly file with the Agent a certificate of a Responsible Officer
setting forth the applicable Conversion Price and setting forth all the
information relevant to a determination of such Conversion Price.

          8.5  Adjustments to the Conversion Price.
               -----------------------------------   

          (a)  The Conversion Price is subject to adjustment hereunder in
certain events, including: (i) the issuance of Common Stock of the Borrower as a
dividend or distribution on Common Stock of the Borrower; (ii) certain
subdivisions and combinations of the Common Stock of the Borrower; (iii) the
issuance to all holders of Common Stock of the Borrower of certain rights or
warrants to purchase Common Stock of the Borrower (provided that the Conversion
Price will be readjusted to the extent that such rights or warrants are not
exercised prior to the expiration thereof); (iv) the distribution to all holders
of Common Stock of the Borrower of shares of Capital Stock of the Borrower
(other than Common Stock) or evidences of Indebtedness of the Borrower or assets
(including securities, but excluding those rights, warrants, dividends and
distributions referred to above or paid in cash); (v) distributions consisting
of cash; and (vi) payment in respect of a tender offer or exchange offer by the
Borrower or any Affiliate of the Borrower. In the event of a distribution to
substantially all holders of the Borrower's Common Stock of rights to subscribe
for additional shares of the Borrower's Capital Stock as provided in clause
(iii) above, the Borrower may, instead of making any adjustment in the
Conversion Price, make proper provision so that each Lender who converts such
Loan after the record date for such distribution and prior to the expiration or
redemption of such rights shall be entitled to receive upon such conversion, in
addition to shares of Common Stock of the Borrower, an appropriate number of
such rights. If any adjustment is required to be made as set forth in clause (v)
above as a result of a cash distribution, such adjustment would be based upon
the full amount of the distribution.

          (b)  If the Borrower issues (i) shares of Common Stock for a
consideration per share less than the current market value per share (determined
as provided in subparagraph (h) of this Section 8.5), or (ii) any securities
convertible into or exchangeable for Common Stock initially deliverable upon
conversion or exchange of such securities that is less than the then current
market value per share (determined as provided in subparagraph (h) of this
Section 8.5) on the date of issuance of such securities (but excluding, among
other things, issuances otherwise permitted under this Agreement (a) pursuant to
any bona fide plan for the 

                                       44
<PAGE>
 
benefit of employees, directors or consultants of the Borrower now or hereafter
in effect; (b) to acquire all or any portion of a business in an arm's-length
transaction between the Borrower and an unaffiliated third party including, if
applicable, issuances upon exercise of options or warrants issued in connection
with such an acquisition; (c) in a bona fide public offering pursuant to a firm
commitment underwriting or sales at the market pursuant to a continuous stock
offering program; and (d) pursuant to the exercise of warrants, rights
(including, without limitation, earnout rights) or options, or upon the
conversion of convertible securities, which are issued and outstanding on the
date hereof, or which may be issued in the future at fair value and with an
exercise price or conversion price at least equal to the current market value of
the Common Stock (determined as provided in subparagraph (h) of this Section
8.5) at the date of issuance of such warrant, right, option or convertible
security), then the Conversion Price of the Loans to be in effect after the date
of such issuance shall be determined by multiplying the Conversion Price thereof
in effect immediately prior to the date of such issuance by a fraction, the
numerator of which shall be the number of shares of such Common Stock
outstanding on the date of, but immediately prior to, such issuance or such
record date plus the number of shares of such Common Stock the
            ----
aggregate offering price of the total number of shares of such Common Stock so
to be issued or to be offered for subscription or purchase (or the aggregate
initial Conversion Price of the convertible securities so to be offered) would
purchase at such then current market price (determined as provided in
subparagraph (h) of this Section 8.5) and the denominator of which shall be the
number of shares of Common Stock outstanding on the date of, but immediately
prior to, such issuance plus the number of additional shares of such Common
                        ----
Stock to be issued or to be offered for subscription or purchase (or into which
the convertible securities so to be offered are initially convertible). In case
such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration shall be as
determined by an independent investment banking firm reasonably acceptable to
the Borrower and the Agent and Lenders holding a majority in principal amount of
such Loans (the cost of the engagement of said investment banking firm to be
borne by the Borrower). Such adjustment shall be made successively whenever the
date of such issuance is fixed (which date of issuance shall be the record date
for such issuance if a record date therefor is fixed); and, in the event that
such shares or options, rights or warrants are not so issued, such Conversion
Price shall again be adjusted to be such Conversion Price which would then be in
effect if the date of such issuance had not been fixed.

          (c)  In the case of (i) any reclassification of the Common Stock of
the Borrower, or (ii) a consolidation, merger or combination involving the
Borrower or a sale or conveyance to another Person of the property and assets of
the Borrower as an entirety or substantially as an entirety, in each case as a
result of which holders of Common Stock shall be entitled to receive stock,
other securities, other property or assets (including cash) with respect to or
in exchange for such Common Stock, the Lenders will generally be entitled
thereafter to convert such Loans for any kind and amount of shares of stock,
other securities or other property or assets (including cash) which they would
have owned or been entitled to receive upon such reclassification,
consolidation, merger, combination, sale or conveyance had such Loans been
converted into Common Stock immediately prior to such reclassification,
consolidation, merger, combination, sale or conveyance assuming that a Lender
would not

                                       45
<PAGE>
 
have exercised any rights of election as to the stock, other securities or other
property or assets (including cash) receivable in connection therewith. In the
event that holders of Common Stock shall have the right to choose between or
among two or more alternatives of stock, other securities, other property or
assets (including cash) in exchange for their Common Stock, the Lenders, upon
conversion of the Loans, shall have the right to choose between or among the
same two or more alternatives; provided that, in the event that the
                               --------
holders of Common Stock shall be subject to restrictions on the percentage of
one or more of the alternatives that they may receive in exchange for their
Common Stock (irrespective of whether the restrictions are on a per share or a
per class basis), each Lender shall be subject to the same restrictions with
respect to the conversion of each Loan on a per Loan basis.

          (d)  In case the Borrower shall pay a dividend or make a distribution
on the Common Stock exclusively in Common Stock or securities convertible or
exchangeable for Common Stock, the Conversion Price in effect at the opening of
business of the day following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution shall be
reduced by multiplying such Conversion Price by a fraction of which the
numerator shall be the number of shares of Common Stock outstanding at the close
of business on the date fixed for such determination and the denominator shall
be the sum of such number of shares and the total number or shares (and/or
shares issuable upon any such conversion or exchange) constituting such dividend
or other distribution, such reduction to become effective immediately after the
opening of business on the day following the date fixed for such determination.
For the purposes of this subparagraph (d), the number of shares of Common Stock
at any time outstanding shall not include shares held in the treasury of the
Borrower.  In the event that such dividend or distribution is not so paid or
made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such dividend or distribution had not occurred.

          (e)  In case outstanding shares of Common Stock shall be subdivided
into a greater number of shares of Common Stock, the Conversion Price in effect
at the opening of business on the day following the day upon which such
subdivision becomes effective shall be proportionately reduced and, conversely,
in case outstanding shares of Common Stock shall each be combined into a smaller
number of shares of Common Stock, the Conversion Price in effect at the opening
of business on the day following the day upon which such combination becomes
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on
the day following the day upon which such subdivision or combination becomes
effective.

          (f)  Subject to the last sentence of this subparagraph (f), in case
the Borrower shall, by dividend or otherwise, distribute to all holders of its
Common Stock evidences of its indebtedness, shares of any class or series of
Capital Stock, cash or assets (including securities, but excluding any rights or
warrants referred to in subparagraph (c) of this Section 8.5, any dividend or
distribution paid exclusively in cash and any dividend or distribution referred
to in subparagraph (c) of this Section 8.5), the Conversion Price shall be
reduced so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this 

                                       46
<PAGE>
 
subparagraph (f) by a fraction of which the numerator shall be the current
market price per share (determined as provided in subparagraph (h) of this
Section 8.5) of the Common Stock on the date fixed for the determination of
stockholders entitled to receive such distribution (the "Reference Date") less
                                                         --------------
the fair market value (as determined good faith by the Board of
Directors of the Borrower, whose determination shall be conclusive and described
in a resolution of the Board of Directors), on the Reference Date, of the
portion of the evidences of Indebtedness, shares of Capital Stock, cash and
assets so distributed applicable to one share of Common Stock and the
denominator shall be such current market price per share of the Common Stock,
such reduction to become effective immediately prior to the opening of business
on the day following the Reference Date. In the event that such dividend or
distribution is not so paid or made, the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect if such
dividend or distribution had not occurred. For purposes of this subparagraph
(f), any dividend or distribution that includes shares of Common Stock or rights
or warrants to subscribe for or purchase shares of Common Stock shall be deemed
instead to be (1) a dividend or distribution of the evidences of Indebtedness,
shares of Capital Stock, cash or assets other than such shares of Common Stock
or, such rights or warrants (making any Conversion Price reduction required by
this subparagraph (f) immediately followed by (2) a dividend or distribution of
such shares of Common Stock or such rights or warrants (making any further
Conversion Price reduction required by subparagraph (c) or (d) of this Section
8.5), except any shares of Common Stock included in such dividend or
distribution shall not be deemed "outstanding at the close of business on the
date fixed for such determination" within the meaning of subparagraph (d) of
this Section 8.5.

          (g)  In case a tender or exchange offer (other than an odd-lot offer)
made by the Borrower or any Subsidiary of the Borrower for all or any portion of
the Borrower's Common Stock shall expire and such tender or exchange offer shall
involve the payment by the Borrower or such Subsidiary of consideration per
share of Common Stock having a fair market value (as determined in good faith by
the Board of Directors, whose determination shall be conclusive and described in
a resolution of: the Board of Directors) at the last time (the "Expiration
                                                                ----------
Time") tenders or exchanges may be made pursuant to such tender or exchange
----
offer (as it shall have been amended) that exceeds 110% of the current market
price per share (determined as provided in subparagraph (h) of this Section 8.5)
of the Common Stock on the Trading Day next succeeding the Expiration Time, the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (g) by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged shares)
at the Expiration Time multiplied by the current market price per share
(determined as provided in subparagraph (h) of this Section 8.5) of the Common
Stock on the Trading Day next succeeding the Expiration Time and the denominator
shall be the sum of (x) the fair market value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to
any maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Expiration Time
(the shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased

                                       47

Shares") and (y) the product of the number of shares of Common Stock
------
outstanding (less any Purchase Shares) at the Expiration Time and the current
market price per share (determined as provided in subparagraph (h) of this
Section 8.5) of the Common Stock on the Trading Day next succeeding the
Expiration Time, such reduction to become effective immediately prior to the
opening of business on the day following the Expiration Time.

          (h)  For the purpose of any computation under subparagraphs (b), (f),
and (g) of this Section 8.5, the current market price per share of Common Stock
on any date in question shall be deemed to be the average of the daily Closing
Prices for the ten consecutive Trading Days prior to the earlier of the day in
question and, if applicable, the day before the "ex" date with respect to the
issuance or distribution requiring such computation; provided, however, that if
                                                     --------                  
another event occurs that would require an adjustment pursuant to subparagraphs
(b) through (h) of this Section 8.5, inclusive, the Board of Directors may make
such adjustments to the Closing Prices during such five Trading Day period as it
deems appropriate to effectuate the intent of the adjustments in this Section
8.5, in which case any such determination by the Board of Directors shall be set
forth in a resolution and shall be conclusive.  For purposes of this paragraph,
the term "ex" date, (1) when used with respect to any issuance or distribution,
means the first date on which the Common Stock is quoted regular way on a
Qualifying Stock Exchange or on such successor securities exchange on which the
Common Stock may be quoted or listed or in the relevant market from which the
Closing Prices were obtained without the right to receive such issuance or-
distribution, and (2) when used with respect to any tender or exchange offer
means the first date on which the Common Stock is quoted regular way on such
securities exchange or in such market after the Expiration Time of such offer.

          (i)  The Borrower may make such reductions in the Conversion Price, in
addition to those required by subparagraphs (c), (d), (e), (f) and (g) of this
Section 8.5, as it considers to be advisable to avoid or diminish any income tax
to holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes.

          (j)  The Borrower from time to time may, to the extent permitted by
law, reduce the Conversion Price by any amount for any period of at least 20
days (provided such reduction is irrevocable during the 20-day period), in which
case the Borrower shall give at least 15 days notice of such reduction, if the
Board of Directors of the Borrower has made a determination that such reduction
would be in the best interests of the Borrower, which determination shall be
conclusive.  The Borrower may, at its option, make such reductions in the
Conversion Price, in addition to those set forth above, as the Board of
Directors of the Borrower deems advisable to avoid or diminish any income tax to
holders of Common Stock resulting from any dividend or distribution of stock (or
rights to acquire stock) or from any event treated as such for income tax
purposes.

          (l)  No adjustment in the Conversion Price will be required unless
such adjustment would require a change of at least 1% in the Conversion Price
then in effect; provided that any adjustment that would otherwise be required to
be made shall be carried 

                                       48
<PAGE>
 
forward and taken into account in any subsequent adjustment. Except as stated
above, the Conversion Price will not be adjusted for the issuance of Common
Stock or any securities convertible into or exchangeable for Common Stock or
carrying the right to purchase any of the foregoing.

          (m)  Nothing in this Section 8.5 or otherwise in this Section 8 shall
be construed to derogate any restriction or limitation contained in any Loan
Document imposed on any transaction of the types described in this Section 8.5,
including without limitation the restrictions set forth in Sections 6.2, 6.5,
6.6, 6.8 and 6.19 hereof.

          (n)  Notwithstanding anything to the contrary set forth in this
Section 8, the Conversion Price shall not be required to be adjusted solely as a
result of the issuance of the Convertible PIK Preferred Stock on the terms set
forth on Schedule 1.1(b).

          8.6  Stamp and Other Duties and Exchange Costs.
               -----------------------------------------    

          Payment of all stamp, transfer and registration duties (if any) and
any brokers' commission and stock exchange transaction charges and any other tax
thereon arising on exercise of Conversion Rights and/or on the transfer or
delivery of shares of Common Stock by the Borrower (or the Agent) to or to the
order of the Agent or the relevant Lender in connection therewith, payable in or
imposed by the United States, any state or other political sub-division thereof
and any other jurisdiction in which the register in the respect of any
securities is located will be made or procured by the Borrower.  If the Borrower
shall fail to pay any such duties or costs, the relevant Lender shall be
entitled to tender and pay the same.  The Borrower shall promptly reimburse each
Lender in respect of the payment of such duties or costs and any penalties paid
in respect thereof.  A Lender exercising Conversion Rights must pay to the Agent
any such duties or costs arising in any other circumstances.

          8.7  Reservation of Shares; Shares to be Fully Paid; Listing of Shares
               -----------------------------------------------------------------
of Common Stock.
----------------   

          (a)  The Borrower shall provide, free from preemptive rights, out of
its authorized but unissued Common Stock held in treasury, sufficient shares to
provide for the conversion of the Loans from time to time as such Loans are
converted as provided herein.

          (b)  The Borrower covenants that all shares of Common Stock issued
upon conversion of Loans will be fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issue thereof.

          (c)  The Borrower further covenants that promptly after the shares of
Common Stock shall have been listed on the New York Stock Exchange, the American
Stock Exchange, the NASDAQ National Market or any other national securities
exchange or automated quotation system the Borrower will, to the extent
permitted by the rules of such exchange or automated quotation system, list and
keep listed, so long as the shares of Common Stock shall be so listed on such
exchange or automated quotation system, all shares of Common Stock issuable upon
conversion of the Loans.

          8.8  Responsibility of the Agent.
               ---------------------------    

          The Agent shall not be accountable with respect to the validity or
value (or the kind or amount) of any shares Common Stock, or of any securities
or property, which may at any time be issued or delivered upon the conversion of
any Loan; and the Agent makes no representations with respect thereto, and is
entitled to rely conclusively on the Borrower therefor.  Subject to the other
provisions of this Agreement, the Agent shall not be responsible for any failure
of the Borrower to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property or cash upon the surrender of
any Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Borrower contained in this Section 8.
Without limiting the generality of the foregoing, the Agent shall be under no
responsibility to determine the correctness of any provisions contained in any
amendment entered into pursuant to Section 8.5 relating either to the kind or
amount of shares of stock or securities or property (including cash) receivable
by Lenders upon the conversion of their Notes after any event referred to in
such Section 8.5 or to any adjustment to be made with respect thereto, but,
subject to the other provisions of this Agreement may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in
relying upon, the certificate of a Responsible Officer (which the Borrower shall
be obligated to file with the Agent prior to the execution of any such 
amendment) with respect thereto.

          8.9  Notice to Lenders Prior to Certain Actions.
               ------------------------------------------    

          In case:

          (a)  of any reclassification of the Common Stock of the Borrower
    (other than a subdivision or combination of its outstanding Common Stock, or
    a change in par value, or from par value to no par value, or from no par
    value to par value), or of any consolidation or merger to which the Borrower
    is a party and for which approval of any stockholders of the Borrower is
    required, or of the sale or transfer of all or substantially all of the
    assets of the Borrower; or

          (b)  of the voluntary or involuntary dissolution, liquidation or
    winding-up of the Borrower;

the Borrower shall cause to be filed with the Agent and to be mailed to each
Lender at its address appearing on the Register, as promptly as possible but in
any event at least 15 days prior to the applicable date hereinafter specified, a
notice stating the date on which such reclassification, consolidation, merger,
sale, transfer, dissolution, liquidation or winding-up is expected to become
effective or occur, and the date as of which it is expected that holders of
shares of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.  Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such dividend, distribution,
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.

          SECTION 9.    THE AGENT

          9.1  Appointment.  Each Lender hereby irrevocably designates and
               -----------                                                  
appoints the Agent as the agent of such Lender under this Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes the Agent, in
such capacity, to take such action on its behalf under the provisions of this
Agreement and the other Loan Documents and to exercise such powers and perform
such duties as are expressly delegated to the Agent by the terms of this
Agreement and the other Loan Documents, together with such other powers as are
reasonably incidental thereto.   Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.

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

          9.3  Exculpatory Provisions.  Neither the Agent nor any of its
               ----------------------                                     
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement or any other Loan Document
(except for its or such Person's own gross negligence or willful misconduct) or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by the Borrower or any officer
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Loan Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document or
for any failure of the Borrower to perform its obligations hereunder or
thereunder.  The Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

          9.4  Reliance by Agent  .  The Agent shall be entitled to rely, and
               -----------------                                             
shall be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Borrower or any other Loan Party),
independent accountants and other experts selected by the Agent.  The Agent may
deem and treat the payee of any Note as the owner thereof for all purposes
unless a written notice of assignment, negotiation or transfer thereof shall
have been filed with the Agent.  The Agent 

                                       51
<PAGE>
 
shall be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Required Lenders as it deems appropriate or it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Agent shall in all cases be fully protected in acting,
or in refraining from acting, under this Agreement and the other Loan Documents
in accordance with a request of the Required Lenders, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Loans.

          9.5  Notice of Default.  The Agent shall not be deemed to have
               -----------------                                          
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from a Lender or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default".  In the event that the Agent
receives such a notice, the Agent shall give notice thereof to the Lenders.  The
Agent shall take such action with respect to such Default or Event of Default as
shall be reasonably directed by the Required Lenders; provided that unless and
                                                      --------                
until the Agent shall have received such directions, the Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Lenders.

          9.6  Non-Reliance on Agent and Other Lenders.  Each Lender expressly
               ---------------------------------------                          
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by the Agent hereinafter taken, including
any review of the affairs of the Borrower or any other Loan Party, shall be
deemed to constitute any representation or warranty by the Agent to any Lender.
Each Lender represents to the Agent that it has, independently and without
reliance upon the Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrower and the other Loan Parties and
made its own decision to make its Loans hereunder and enter into this Agreement.
Each Lender also represents that it will, independently and without reliance
upon the Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigation as it
deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrower. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Agent hereunder or under the other Loan Documents, the Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of the Borrower or any
other Loan Party which may come into the possession of the Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

          9.7  Indemnification.  The Lenders agree to indemnify the Agent in
               ---------------                                                
its capacity as such (to the extent not reimbursed by the Borrower and without
limiting the 

                                       52

obligation of the Borrower to do so), ratably according to their respective
Credit Exposure Percentages in effect on the date on which indemnification is
sought, from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Loans)be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of, the Commitments,
this Agreement, any of the other Loan Documents or any documents contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by the Agent under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment of
                      --------
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting solely
from the Agent's gross negligence or willful misconduct. The agreements in this
Section shall survive the payment of the Loans and all other amounts payable
hereunder.

          9.8  Agent in Its Individual Capacity.  The Agent and its Affiliates
               --------------------------------                                 
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrower and the other Loan Parties as though the Agent were
not the Agent hereunder and under the other Loan Documents.  With respect to the
Loans made by it, the Agent shall have the same rights and powers under this
Agreement and the other Loan Documents as any Lender and may exercise the same
as though it were not the Agent, and the terms "Lender" and "Lenders" shall
                                                ------       -------       
include the Agent in its individual capacity.

          9.9  Successor Agent.  The Agent may resign as Agent upon 10 days'
               ---------------                                                
notice to the Lenders.  If the Agent shall resign as Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent for the Lenders, which successor agent shall be
approved by the Borrower, whereupon such successor agent shall succeed to the
rights, powers and duties of the Agent, and the term "Agent" shall mean such
                                                      -----                 
successor agent effective upon such appointment and approval, and the former
Agent's rights, powers and duties as Agent shall be terminated, without any
other or further act or deed on the part of such former Agent or any of the
parties to this Agreement or any holders of the Loans.  After any retiring
Agent's resignation as Agent, the provisions of this Section 9 shall inure to
its benefit as to any actions taken  or omitted to be taken by it while it was
Agent under this Agreement and the other Loan Documents.

          SECTION 10.   MISCELLANEOUS

          10.1 Amendments and Waivers.  Neither this Agreement nor any other
               ----------------------                                         
Loan Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1.  The
Required Lenders may, or, with the written consent of the Required Lenders, the
Agent may, from time to time, (a) enter into with the Borrower written
amendments, supplements or modifications hereto and to the other Loan Documents
for the purpose of adding any provisions to this Agreement or the other Loan
Documents or changing in any manner the rights of the Lenders or of the Borrower
hereunder or thereunder or (b) waive, on such terms and conditions as the
Required Lenders or the 

                                       53
<PAGE>
 
Agent, as the case may be, may specify in such instrument, any of the
requirements of this Agreement or the other Loan Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver
                                       -----------------
and no such amendment, supplement or modification shall (i) reduce the amount or
extend the scheduled date of maturity of any Loan or of any installment thereof,
or reduce the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof or increase the amount or extend the
expiration date of any Lender's Commitment, in each case without the consent of
each Lender affected thereby, or (ii) amend, modify or waive any provision of
this Section 10.1 or reduce the percentage specified in the definition of
Required Lenders, or consent to the assignment or transfer by the Borrower of
any of its rights and obligations under this Agreement and the other Loan
Documents or release all or substantially all of the Collateral or release all
or substantially all of the Subsidiary Guarantors from their obligations under
the Subsidiaries Guarantee, in each case without the written consent of all the
Lenders, or (iii) amend, modify or waive any provision of Section 9 without the
written consent of the then Agent. Any such waiver and any such amendment,
supplement or modification shall apply equally to each of the Lenders and shall
be binding upon the Borrower, the Lenders, the Agent and all future holders of
the Loans. In the case of any waiver, the Borrower, the Lenders and the Agent
shall be restored to their former positions and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon.

violation of, noncompliance with or liability under, any Environmental Law
applicable to the operations of the Borrower, any of its Subsidiaries, the

collectively, the "indemnified liabilities"), provided, that the Borrower shall
                   -----------------------    --------
have no obligation hereunder to the Agent or any Lender with respect to
indemnified liabilities arising from (i) the gross negligence or willful
misconduct of the Agent or any such Lender or (ii) legal proceedings commenced
against the Agent or any such Lender by any security holder or creditor thereof
arising out of and based upon rights afforded any such security holder or
creditor solely in its capacity as such. The agreements in this Section shall
survive repayment of the Loans and all other amounts payable hereunder. 

          10.6 Successors and Assigns; Participations and Assignments.
               ------------------------------------------------------
          (a)  This Agreement shall be binding upon and inure to the benefit of
the Borrower, the Lenders, the Agent and their respective successors and
assigns, except that the Borrower may not assign or transfer any of its rights
or obligations under this Agreement without the prior written consent of each
Lender.

          (b)  Any Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other entities ("Participants") participating interests in any Loan
                          ------------                                      
owing to such Lender, any Commitment of such Lender or any other interest of
such Lender hereunder and under the other Loan Documents.  In the event of any
such sale by a Lender of a participating interest to a Participant, such
Lender's obligations under this Agreement to the other parties to this Agreement
shall remain unchanged, such Lender shall remain solely responsible for the
performance thereof, such Lender shall remain the holder of any such Loan for
all purposes under this Agreement and the other Loan Documents, and the Borrower
and the Agent shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement and
the other Loan Documents.  The Borrower agrees that if amounts outstanding under
this Agreement are due or unpaid, or shall have been declared or shall have
become due and payable upon the occurrence of an Event of Default, each
Participant shall, to the maximum extent permitted by applicable law, be deemed
to have the right of setoff in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, provided that, in purchasing such participating interest, such
           --------                                                      
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in Section 10.7(a) as fully as if it were a Lender
hereunder.  The Borrower also agrees that each Participant shall be entitled to
the benefits of Sections 2.9 and 2.10 with respect to its participation in the
Commitments and the Loans outstanding from time to time as if it was a Lender;
provided that, in the case of Section 2.10, such Participant shall have complied
--------                                                                        
with the requirements of said Section and provided, further, that no Participant
                                          --------  -------                     
shall be entitled to receive any greater amount pursuant to any such Section
than the transferor Lender would have been entitled to receive in respect of the
amount of the participation transferred by such transferor 

                                       56
<PAGE>
 
Lender to such Participant had no such transfer occurred.

          (c)  Any Lender may, in accordance with applicable law, at any time
and from time to time assign to any Lender or any affiliate thereof or, with the
consent of the Agent (which shall not be unreasonably withheld), to an
additional bank or financial institution ("an Assignee") all or any part of its
                                              --------                         
rights and obligations under this Agreement and the other Loan Documents
pursuant to an Assignment and Acceptance, substantially in the form of Exhibit
J, with appropriate completions (an "Assignment and Acceptance"), executed by
                                     -------------------------               
such Assignee, such assigning Lender (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof, by  the Agent) and delivered to the
Agent for its acceptance and recording in the Register.  Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be
a party hereto and, to the extent provided in such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder with Commitments as set
forth therein, and (y) the assigning Lender thereunder shall, to the extent
provided in such Assignment and Acceptance, be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering
all or the remaining portion of an assigning Lender's rights and obligations
under this Agreement, such assigning Lender shall cease to be a party hereto).

          (d)  The Agent, on behalf of the Borrower, shall maintain at the
address of the Agent referred to in Section 10.2 a copy of each Assignment and
Acceptance delivered to it and a register (the "Register") for the recordation
                                                --------                      
of the names and addresses of the Lenders and the Commitment of, and principal
amount of the Loans owing to, each Lender from time to time.  The entries in the
Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Agent and the Lenders may (and, in the case of any Loan or other
obligation hereunder not evidenced by a Note, shall) treat each Person whose
name is recorded in the Register as the owner of a Loan or other obligation
hereunder as the owner thereof for all purposes of this Agreement and the other
Loan Documents, notwithstanding any notice to the contrary.  Any assignment of
any Loan or other obligation hereunder not evidenced by a Note shall be
effective only upon appropriate entries with respect thereto being made in the
Register.  The Register shall be available for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an Assignee (and, in the case of an Assignee that is not
then a Lender or an affiliate thereof, by the Agent) together with payment to
the Agent of a registration and processing fee of $3,500, the Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give notice of such acceptance and recordation to the Lenders and
the Borrower.

          (f)  The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
subject to the provisions of 

                                       57
<PAGE>
 
Section 10.16, any and all financial information in such Lender's possession
concerning the Borrower and its Affiliates which has been delivered to such
Lender by or on behalf of the Borrower pursuant to this Agreement or which has
been delivered to such Lender by or on behalf of the Borrower in connection with
such Lender's credit evaluation of the Borrower and its Affiliates prior to
becoming a party to this Agreement.

          (g)  For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this Section concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank
in accordance with applicable law.

          10.7 Adjustments; Set-off.  (a)  If any Lender (a "benefited
               --------------------                          ---------
Lender") shall at any time receive any payment of all or part of its Loans, or
interest thereon, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in Section 7(f), or otherwise), in a greater proportion
than any such payment to or collateral received by any other Lender, if any, in
respect of such other Lender's Loans, or interest thereon, such benefited Lender
shall purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Loan, or shall provide such other Lenders
with the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefited Lender to share the excess payment or benefits
of such collateral or proceeds ratably with each of the Lenders; provided,
                                                                 -------- 
however, that if all or any portion of such excess payment or benefits is
-------                                                                  
thereafter recovered from such benefited Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest.  The Borrower agrees that each Lender so
purchasing a portion of another Lender's Loan may exercise all rights of payment
(including, without limitation, rights of set-off) with respect to such portion
as fully as if such Lender were the direct holder of such portion.

          (b)  In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrower, any
such notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise) to set-
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency thereof to or for the
credit or the account of the Borrower.  Each Lender agrees promptly to notify
the Borrower and the Agent after any such set-off and application made by such
Lender, provided that the failure to give such notice shall not affect the
        --------                                                          
validity of such set-off and application.

          10.8 Counterparts.  This Agreement may be executed by one or more
               ------------                                                  
of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission of signature pages hereto), and all of said
counterparts taken together shall be 

                                       58
<PAGE>
 
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Borrower and the
Agent.

          10.9 Severability.  Any provision of this Agreement which is
               ------------                                             
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         10.10 Integration.  This Agreement and the other Loan Documents
               -----------                                               
represent the agreement of the Borrower, the Agent and the Lenders with respect
to the subject matter hereof, and there are no promises, undertakings,
representations or warranties by the Agent or any Lender relative to subject
matter hereof not expressly set forth or referred to herein or in the other Loan
Documents.

         10.11 GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
               -------------                                                 
OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     Southern District of New York, and appellate courts from any thereof;

          (b)  consents that any such action or proceeding may be brought in
     such courts and waives any objection that it may now or hereafter have to
     the venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c)  agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     Borrower at its address set forth in Section 10.2 or at such other address
     of which the Agent shall have been notified pursuant thereto;

          (d)  agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the
     right to sue in any other jurisdiction; and

                                       59
<PAGE>
 
          (e)  waives, to the maximum extent not prohibited by law, any right it
     may have to claim or recover in any legal action or proceeding referred to
     in this Section any special, exemplary, punitive or consequential damages.

         10.13 Acknowledgments.  The Borrower hereby acknowledges that:
               ---------------                                          

          (a)  it has been advised by counsel in the negotiation, execution and

pertaining to indebtedness of the Borrower or the Subsidiary Guarantors to the
Agent or the Lenders, in no contingency or event whatsoever, whether by

from any circumstances whatsoever fulfillment of any provisions of this Loan
Agreement, the Note, the other Loan Documents or of any other document
evidencing, securing, guaranteeing or otherwise pertaining to indebtedness of
the Borrower or the Subsidiary Guarantors to the Agent or the Lender, at the
time performance of such provision shall be due, shall involve transcending the
limit of validity prescribed by law, then, ipso facto, the obligation to be
fulfilled shall be reduced to the limit of such validity, and if from any such
circumstances the Agent or the Lenders shall ever receive anything of value as
interest or deemed interest by applicable law under this Loan Agreement, the
Note, the other Loan Documents or any other document evidencing, securing,
guaranteeing or otherwise pertaining to indebtedness of the Borrower or the
Subsidiary Guarantors to the Agent or the Lenders or otherwise an amount that
would exceed the highest lawful amount, such amount that would be excessive
interest shall be applied to the reduction of the principal amount owing in
connection with this Loan Agreement or on account of any other indebtedness of
the Borrower or the Subsidiary Guarantors to the Agent or the Lender, and not to
the payment of interest, or if such excessive interest exceeds the unpaid
balance of principal owing in connection with this Loan Agreement and such other
indebtedness, such excess shall be refunded to the Borrower or the Subsidiary
Guarantors. In determining whether or not the interest paid or payable with
respect to indebtedness of the Borrower or the Subsidiary Guarantors to the
Agent or the Lender, under any specific contingency, exceeds the maximum
nonusurious rate permitted under applicable law, the Borrower or the Subsidiary
Guarantors and the Agent or the Lender shall, to the maximum extent permitted by
applicable law, (a) characterize any non-principal payment as an expense, fee or
premium rather than as interest, (b) exclude voluntary prepayments and the
effects thereof, (c) amortize, prorate, allocate and spread the total amount of
interest throughout the full term of such indebtedness so that the actual rate
of interest on account of such indebtedness does not exceed the maximum amount
permitted by applicable law, and/or (d) allocate interest between portions of
such indebtedness, to the end that no such portion shall bear interest at a rate
greater than that permitted by law. The terms and provisions of this paragraph
shall control and supersede every other conflicting provision of this Loan
Agreement, the Note and the other Loan Documents.
