Seller within the Review Period, Buyer shall be conclusively deemed to have
accepted the Preliminary Closing Balance Sheet.

         In the event that Buyer shall accept or shall be conclusively deemed to
have accepted the Preliminary Closing Balance Sheet as prepared and delivered by
Seller, the Preliminary Closing Balance Sheet shall constitute the Final Closing
Balance Sheet for purposes of determining any Adjustment (as defined in Section
2.8) to the Cash Purchase Price.

         2.6 RESOLUTION OF DISPUTES REGARDING PRELIMINARY CLOSING BALANCE SHEET.
In the event that Buyer shall object to the Preliminary Closing Balance Sheet
within the Review Period, Buyer and Seller shall promptly meet and in good faith
attempt to resolve such objections. If any of such objections of Buyer cannot be
resolved between Buyer and Seller within 30 days following Seller's receipt of
Buyer's statement of objections, then Seller and Buyer shall submit the dispute
to a nationally recognized "Big 5" independent accounting firm mutually
agreeable to Seller and Buyer, which firm shall not have had a material
relationship with either Seller or Buyer or their respective affiliates within
the three years preceding the appointment (the "Arbiter"), for resolution.
Promptly, but no later than 60 days after its acceptance of its appointment as
Arbiter, the Arbiter shall determine (based solely on presentations by Seller
and Buyer to the Arbiter and not by independent review) only those issues in
dispute and shall render a report as to the disputes and the



                                       11
<PAGE>   13


resulting calculation of the Closing Net Asset Value and the Adjustment, if any,
which shall be conclusive and binding upon the parties. In resolving any
disputed item, the Arbiter may not assign a value to any item greater than the
greatest value for such items claimed by either party, or less than the smallest
value for such item claimed by either party, in each case, as presented to the
Arbiter. The fees, costs and expenses of the Arbiter shall be paid one-half by
Seller and one-half by Buyer. The resolution so made shall be final and binding
on the parties, and the Preliminary Closing Balance Sheet, as adjusted to
reflect the adjustments agreed upon by the parties or determined by the Arbiter,
shall constitute the Final Closing Balance Sheet for purposes of determining any
Adjustment to the Cash Purchase Price.

         2.7 PAYMENT AT CLOSING. On the Closing, Buyer will pay to Seller the
sum of Twelve Million Twelve Thousand Six Hundred and Fifty-Nine Dollars
($12,012,659) by wire transfer of immediately available federal funds to
Seller's bank account #58-04493 in the name of "AAR CORP Depository" at the
First National Bank of Chicago, One First National Plaza, Chicago, Illinois
60670 ABA # 071000013.

         2.8 SETTLEMENT OF CASH PURCHASE PRICE. In the event that the Cash
Purchase Price as finally determined is greater or less than the $12,012,659
(such excess or deficiency being referred to herein as the "Adjustment"), on the
third business day following 



                                       12
<PAGE>   14


the date upon which the Cash Purchase Price is finally determined as provided
for in Section 2.5 or 2.6, Buyer shall pay and remit to Seller if the Cash
Purchase Price is greater than $12,012,659 or Seller shall pay and remit to
Buyer if the Cash Purchase Price is less than $12,012,659, the amount of the
Adjustment, in either case, plus interest on such amount from the Closing to the
date the Adjustment is paid, at 6% per annum. Payment of the Adjustment and the
applicable interest shall be made by wire transfer of immediately available
federal funds to such bank account as is specified by written instructions given
by the recipient of the Adjustment to the party paying the Adjustment.

         2.9 ALLOCATION OF PURCHASE PRICE. The Purchase Price shall be allocated
among the Transferred Assets for all purposes as agreed upon by the parties.
Seller and Buyer agree that the respective amounts allocated to the various
Transferred Assets constitute the bargained value of the Transferred Assets and
covenants and agreements of Seller herein. Each agrees that it will not take a
position on any income tax return or in any proceeding regarding collection of
any tax which is materially inconsistent with the allocations agreed upon.

transferred to, and assumed by, Buyer hereunder are not assignable or
transferable either by virtue of the provisions thereof or under applicable law
without the consent of some party or parties, Seller will use its best efforts
to obtain such consents prior to the Closing. If any such consent cannot be
obtained prior to the Closing and Buyer elects to close, this agreement shall
not constitute an assignment or transfer thereof and Buyer shall not assume
Seller's obligations with respect thereto, but Seller shall to the extent

at the same prices provided for therein and otherwise to complete such contracts
on behalf of Seller. Buyer shall provide all services and bear all costs
necessary to complete such contracts, and Seller shall promptly remit to Buyer
amounts received with respect to such contracts. Seller shall take such steps to
collect overdue amounts owed with respect to such contracts as a reasonable and
prudent business person would take to collect similar amounts for his own
account. If Seller has been dissolved or otherwise fails to comply with the
provisions of this Section 3.3, Buyer may on its own behalf 



                                       17
<PAGE>   19


undertake to complete such contracts and collect amounts due thereunder in the
name of Seller.

      12.1  NON-COMPETITION

      (a) For a period of three (3) years following the date of the Closing,
Seller shall not engage or participate directly or indirectly in any business
which is competitive with the business conducted by Seller in any of the states
or territories of the United States or any foreign territories, where Seller has
heretofore conducted its business or where Buyer has heretofore conducted its
business so long as Buyer, its successors and assigns shall carry on a like
business therein. Further, the Seller agrees that for a period of eighteen (18)
months following the date of the Closing, neither Seller nor AAR Corp. shall
solicit, directly or indirectly, any of the Seller's employees who are employed
by Buyer as of the Closing Date and continue to be employed by Buyer for such 18
month period, for any employment, consulting or other position without the
express written authorization of Buyer.

      (b) The foregoing covenant shall be deemed to be a series of separate
covenants, one for each of the states of the United States and all applicable
foreign jurisdictions. If in any judicial proceeding a court shall refuse to
enforce one or more of these separate covenants deemed included herein, such
unenforceable covenant shall be deemed eliminated from the provisions hereof for
the purpose of such proceedings to the


                                       51

empowers Buyer, from time to time after the Closing: (i) to receive and open all
mail and other communications to Seller received by Buyer; and (ii) to deal with
the contents of such communications at its sole expense and in any proper manner
if such communications relate to the business conducted by Buyer after the
Closing or to the Transferred Assets. If such communications do not relate to
the business conducted by Buyer after the Closing or the Transferred Assets, it
will be forwarded to Seller.

      (b) Seller shall transmit by wire funds to Buyer on the first business day
of each week all Receivables received during the immediately preceding week and

by any of the property insurance policies required to be maintained pursuant to
the terms of this Lease and covenant and agree to obtain a waiver or waivers in
writing from the carrier of such insurance releasing such carrier's subrogation
rights as against Landlord and Tenant.

     13. DAMAGE AND CONDEMNATION.

         13.1 DAMAGES OR DESTRUCTION.

         (a) In the event of damage to, or destruction of, any improvements on
     the Premises, by fire or other casualty, Landlord shall repair, restore or
     rebuild the same to the condition existing prior to the happening of such
     fire or other casualty; provided, however, that if the damage or
     destruction is material and substantial, and in Landlord's reasonable
     judgment, the Premises cannot be repaired, restored or rebuilt within 180
     days after the date of the casualty, Tenant or Landlord shall have the
     right to terminate this Lease, effective on the date of such damage or
     destruction, by giving written notice thereof to the other party within 30
     days after the event causing the damage or destruction.  During the period
     of repair the Rent shall be reduced to an amount which bears the same
     ratio as the portion of the Premises then available for use bears to the
     entire Premises.


                                      5



<PAGE>   9




                (b) Tenant or Landlord shall immediately upon receipt thereof
     deposit all insurance proceeds received with respect to such loss into a
     construction escrow account under the terms of a construction escrow
     mutually acceptable to Landlord and Tenant (the "CONSTRUCTION ESCROW").
     Landlord may withdraw such funds from the Construction Escrow as needed to
     pay for the repair or rebuilding of the Premises.  If Landlord shall not
     commence the repair or rebuilding of the improvements within a period of
     sixty (60) days after damage or destruction by fire or otherwise, and
     prosecute the same thereafter with such dispatch as may be necessary to
     complete the same within a reasonable period after said damage or
     destruction occurs, not to exceed one hundred twenty (120) days after the
     date of commencement of such repair or rebuilding, then, in addition to
     whatever other remedies Tenant may have either under this Lease, at law or
     in equity, Tenant may (i) but shall not be obligated to, perform such
     repairs at Landlord's expense and may use the funds then remaining in the
     Construction Escrow to complete such restoration, or (ii) terminate this
     Lease.

          13.2  CONDEMNATION.

                (a) TAKING OF WHOLE.  If the whole of the Premises shall be
     taken or condemned for a public or quasi public use or purpose by a
     competent authority, or if such a portion of the Premises shall be so taken
     that, in Tenant's reasonable discretion, Tenant concludes that as a result
     thereof the balance cannot be used for the same purpose and with
     substantially the same utility to Tenant as immediately prior to such
     taking, then in any of such events, the Lease shall terminate upon delivery
     of possession to the condemning authority, and any award, compensation or
     damages (hereinafter sometimes called the "AWARD") shall be paid to and be
     the sole property of Landlord.  Tenant shall have the right to make its own
     claim against the condemning authority for any separate award that may be
     made by the condemning authority for Tenant's loss of business or for the
     taking of or injury to Tenant's improvements, or on account of any costs or
     loss Tenant may sustain in the removal of Tenant's trade fixtures,
     equipment, furnishings or other removable personal property, or as a result
     of any alterations, modifications, or repairs which may be required by
     Tenant in order to place the remaining portion of the Premises in a
     suitable condition for the continuance of Tenant's business in the
     Premises.

                (b) PARTIAL TAKING.  If only a part of the Leased Premises shall
     be so taken or condemned, but the Lease is not terminated pursuant to
     Section 13.2(a) hereof, Landlord, at its sole cost and expense, shall
     repair and restore the Premises and all improvements to a complete
     architectural unit and the Rent will be adjusted accordingly on a per
     square foot basis (at the rate of $_____ per square foot of building
     space).  Landlord shall deposit any Award received by Landlord in a
     Construction Escrow.  If Landlord does not commence to promptly restore the
     Premises to a complete architectural unit or does not 


                                      6



<PAGE>   10



     complete such restoration within a reasonable period after such taking
     or condemnation, not to exceed one hundred twenty (120) days, then Tenant
     may, but shall not be obligated to, terminate the Lease.

     14. INDEMNITY.

         14.1 INDEMNITY BY TENANT.   Tenant shall indemnify, defend (by counsel
reasonably approved by Landlord) and hold harmless Landlord, its officers,
directors, shareholders, employees and agents against and from any and all
claims, causes of action, liabilities, damages, penalties, costs and expenses
(including, without limitation, reasonable attorneys' fees) arising from (i)
the occupancy or conduct of business by Tenant on or about the Premises during
the term of this Lease, (ii) any breach or default on the part of Tenant in the
performance of any covenant or agreement on the part of Tenant to be performed
pursuant to the terms of this Lease, and (iii) any act or negligence of Tenant
or any of Tenant's agents, contractors, servants, employees or licensees, or
arising from any accident, injury or damage whatsoever caused to any person or
entity (other than to the extent caused by Landlord or Landlord's employees,
agents or contractors) occurring on the Premises during the term of this Lease.

         14.2  INDEMNITY BY LANDLORD.  Landlord shall indemnify, defend (by
counsel reasonably approved by Tenant) and hold harmless Tenant, its officers,
directors, shareholders, employees and agents, against and from any and all
claims, causes of action, liabilities, damages, costs and expenses (including,
without limitation, reasonable attorneys' fees) arising from (i) claims arising
from the ownership of the Premises, or the occupancy, use or conduct of
business on or about the Premises prior to the term of this Lease, (ii) any
breach of any representation or warranty hereunder or default on the part of
Landlord in the performance of any covenant or agreement on the part of
Landlord to be performed pursuant to the terms of this Lease, (iii) any act or
negligence of Landlord or any of Landlord's agents, contractors, employees or
licensees occurring on or about the Premises during or prior to the term of
this Lease, (iv)  any accident, injury or damage whatsoever caused to any
person or entity (other than those to the extent caused by Tenant or Tenant's
employees, agents or contractors) occurring on or about the Premises prior to
the term of this Lease; and (v) the failure of the Premises to comply with all
applicable federal, state and local health, safety, zoning, or building codes
and regulations to the extent the condition giving rise to such failure to
comply existed prior to the term of this Lease.

     15. RETURN OF PREMISES. Subject to Section 10.2 hereof, Tenant agrees to
deliver to Landlord physical possession of the Premises upon the termination of
the Lease in the same degree of repair as of the Commencement Date, excepting
ordinary wear and tear and damage from fire or any other casualty.

                                      7


<PAGE>   11



     16. HOLDOVER.  Should Tenant continue to occupy the Premises after
expiration of the term or any renewal thereof Tenant shall be deemed to be
occupying the Premises without claim or right and Tenant shall pay Landlord all
costs arising out of loss or liability resulting from delay by Tenant in so
surrendering the Premises as above provided (excluding consequential damages)
and shall pay a charge for each day of occupancy an amount equal to 150% of the
Rent (on a per diem basis) then reserved hereunder.

     17. EVENTS OF DEFAULT; REMEDIES.

         17.1 EVENTS OF DEFAULT.

         (a)  Each of the following events shall constitute an Event of Default:

              (i)   if Tenant shall fail to pay any rent or any other charge or
         sum to be paid by Tenant to Landlord when due in accordance with the
         terms of this Lease and such default shall continue for a period of ten
         (10) business days after written notice thereof to Tenant;

              (ii)  if Tenant shall fail to keep or perform or abide by any
         other requirement, term, condition, covenant or agreement of this Lease
         and such default shall continue for a period of thirty (30) days after
         written notice to Tenant of such default, and, if more than thirty (30)
         days shall reasonably be required to correct the breach complained of
         in such notice, then if Tenant shall fail to commence promptly to
         correct such breach and prosecute the same to completion with
         reasonable diligence;

              (iii) if Tenant shall be adjudged an involuntary bankrupt, or a
         decree or order approving, as properly filed, a petition or answer
         filed against Tenant asking reorganization of Tenant under the federal
         bankruptcy laws as now or hereafter amended, or under the laws of any
         state, shall be entered, and any such decree or judgment or order shall
         not have been vacated or set aside within sixty (60) days from the date
         of the entry or granting thereof;

              (iv)  if Tenant shall file or admit the jurisdiction of the court
         and the material allegations contained in any petition in bankruptcy or
         any petition pursuant or purporting to be pursuant to the federal
         bankruptcy laws as now or hereafter amended;

              (v)   if Tenant shall institute any proceeding or shall give its
         consent 


                                      8


<PAGE>   12


     to the institution of any proceedings for any relief of Tenant under
     any bankruptcy or insolvency laws or any laws relating to the relief of
     debtors, readjustment of indebtedness, reorganization, arrangements,
     composition or extension; or

         (vi) if Tenant shall make any assignment for the benefit of creditors
     or shall apply for or consent to the appointment of a receiver for Tenant;
     or a decree or order appointing a receiver of the property of Tenant shall
     be made and such decree or order shall not have been vacated or set aside
     within sixty (60) days from the date of entry or granting thereof.

     17.2 REMEDIES.  Upon the occurrence of any one or more Events of Default,
Landlord may at its election terminate this Lease or terminate Tenant's right
to possession only, without terminating the Lease.  Upon termination of the
Lease, or upon any termination of Tenant's right to possession without
termination of the Lease, Tenant shall surrender possession and vacate the
Premises immediately, and deliver possession thereof to Landlord, and hereby
grants to Landlord the full and free right, in compliance with applicable law,
to enter into and upon the Premises in such event with process of law and to
repossess the Premises as Landlord's former estate and to expel or remove
Tenant and any others who may be occupying or within the Premises without being
deemed in any manner guilty of trespass, eviction, or forcible entry or
detainer, and without relinquishing Landlord's rights to Rent or any other
right given to Landlord hereunder or by operation of law.  Upon termination of
the Lease, Landlord shall be entitled to recover as damages all Rent and other
sums due and payable by Tenant on the date of termination, plus an amount equal
to the present value of the Rent and other sums provided herein to be paid by
Tenant for the residue of the Term hereof.  If Landlord elects to terminate
Tenant's right to possession only without terminating the Lease, Landlord may,
at Landlord's option, enter into the Premises, remove Tenant's signs and other
evidences of tenancy, and take and hold possession thereof as hereinafter
provided, without such entry and possession terminating the Lease or releasing
Tenant, in whole or in part, from Tenant's obligations to pay the Rent and
other sums provided herein to be paid by Tenant for the full term or from any
other of its obligations under this Lease, without acceleration.  Landlord may
relet all or any part of the Premises for such Rent and upon such terms as
shall be reasonably satisfactory to Landlord.  For the purpose of such
reletting, Landlord may decorate or make any repairs in or to the Premises that
may be reasonably necessary.  If Landlord does not relet the Premises, Tenant
shall pay to Landlord on demand damages equal to the amount of the Rent, and
other sums provided herein to be paid by Tenant for the remainder of the Term.
If the Premises are relet and a sufficient sum shall not be realized from such
reletting after paying all of the reasonable expenses of such decorations and
repairs, to satisfy the Rent and other sums herein provided to be paid for the
remainder of the Term, Tenant shall pay to Landlord on demand any 


                                      9


<PAGE>   13


deficiency and Tenant agrees that Landlord may file suit to recover any Rent or
other sums falling due under the terms of this Section 17.2 from time to
time.  Landlord shall use reasonable good faith efforts to mitigate its damages
arising out of Tenant's default.

          17.3 LANDLORD DEFAULTS.  If Landlord defaults in the performance of 
any of its obligations, covenants and warranties hereunder and such default
continues for a period of thirty (30) days after written notice thereof to
Landlord from Tenant specifying the nature of such default, or such additional
period as Landlord may reasonably require to cure the same (except in an
emergency, Landlord shall fail to cure immediately), in addition to all other
rights and remedies available to Tenant, Tenant may, at its option, cure the
same on behalf of Landlord, whereupon the cost of such cure shall be immediately
due and payable to Tenant from Landlord upon written demand therefor by Tenant.

     18.  HAZARDOUS SUBSTANCES. Intentionally Omitted.

     19.  NOTICE.  All notices or demands required or permitted to be given or

of the payment or collection of any Excess Interest. Notwithstanding the
foregoing, if any interest payment or other charge or fee payable hereunder or
under any of the other Loan Documents exceeds the maximum amount then permitted
by applicable law, then to the extent permitted by law, Borrower shall be
obligated to pay the maximum amount then permitted by applicable law and
Borrower shall continue to pay the maximum amount from time to time permitted
by applicable law until all such interest payments and other charges and fees
otherwise due hereunder or under any of the other Loan Documents (in the
absence of such restraint imposed by applicable law) have been paid in full.

     (d) CHARGES TO LOAN ACCOUNT.  Lender may, at its option, charge any
interest and fees payable hereunder or under any of the other Loan Documents to
Borrower's Loan Account, and any amounts so charged shall thereupon constitute
Obligations hereunder, and shall thereafter accrue interest as provided in this
Agreement.

     2.6 FEES.  In consideration of Lender's establishing the Maximum Facility
hereunder and making of the Loans hereunder, Borrower shall pay to Lender:

     (a) Loan Fee.  A one (1) time loan fee in the amount of Twenty-One
Thousand and No/100 Dollars ($21,000.00), due upon Closing.

     (b) Out-of-Pocket Fees. All reasonable out-of-pocket fees, costs and
expenses ("Out-of-Pocket Fees and Costs"), incurred by Lender in connection
with any matters contemplated by or arising out of this Agreement, or any other
Loan Document, all of which shall be part of the Obligations, payable on
demand, including without limitation the following: (i) expenses in verifying
or inspecting the Borrower's Books with respect hereto; (ii) wire transfer fees
in connection with Lender's forwarding to Borrower the proceeds of the

<PAGE>   14


rights of inspection under this Agreement or any other Loan Document or in
connection with any service utilized by Lender to perform such functions; (iv)
expenses in connection with the documentation, negotiation and closing of the
Revolving Loan and Term Loan (including any and all amendments or waivers with
respect hereto), including without limitation, reasonable fees, costs and
expenses of Lender for attorneys and paralegals (provided that such costs set
forth in (i) through (iv) shall not exceed, in the aggregate, $5,000.00); (v)
costs and expenses to correct any Event of Default or enforce any provision
hereof.

     2.7 PAYMENT DATES. Any payment due under this Agreement on any day other
than a Business Day shall be due on the next succeeding Business Day, and such
payment shall bear interest in accordance herewith until actually received.

     2.8 REGULATIONS AFFECTING LOANS. If (a) Regulation D or any other
regulation of the Board of Governors of the Federal Reserve System or any other
Federal regulation, or (b) after the date hereof, the adoption of any
applicable law, rule or regulation, or any change, amendment to, deletion from
or revision, modification or other change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or by any court, or compliance by Lender with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency,

     (i) shall impose, modify or deem applicable any reserve (including,
without limitation, any reserve imposed by the Federal Reserve Board), special
deposit, special assessment or similar requirement against assets of, deposits
with or for the account of, or credit extended by Lender; or

     (ii) shall impose on Lender any other condition affecting the Loans; and
the result of any of the foregoing is to increase the cost to Lender of making
or maintaining the Loans, or to reduce the amount of any sum received or
receivable by  Lender under this Agreement or under any Note with respect
thereto, then on the earlier of termination of this Agreement or fifteen days
after demand, unless such increased cost is a direct result of an increase
required by a regulatory body in Lender's capital and Borrower immediately
notifies Lender in writing of its intention to prepay the Obligations in full
within ninety (90) days of such demand, and makes payment to Lender of the
Obligations within such ninety (90) day period, Borrower shall pay to Lender
from time to time such additional amount or amounts as Lender reasonably
determines will compensate Lender for such increased cost or such reduction.

     2.9 INDEMNITY.  The Borrower shall indemnify Lender against any loss, fee,
claim, damage, liability or expense which Lender may sustain or incur as a
consequence of (i) any failure by the Borrower to fulfill on the date of any
borrowing hereunder the applicable conditions set forth in this Agreement, (ii)
any failure by the Borrower to borrow hereunder after notice of borrowing
pursuant to this Agreement has been given, (iii) any payment or prepayment
required by any provision of this Agreement, other than Section 2.10 of this
Agreement, and made on a date other than the last day of the applicable
Interest Period, or (iv) the occurrence of any Event of Default. 

                                     14


<PAGE>   15


Such loss or reasonable expense shall include, without limitation, an amount
equal to the excess, if any, as reasonably determined by Lender of its cost of
obtaining the funds for the Loan being paid or prepaid or not borrowed (based
on the Libor Rate applicable thereto) for the period from the date of such
payment, prepayment or failure to borrow to the last day of the Interest Period
for such Loan (or, in the case of a failure to borrow, the Interest Period for
such Loan which would have commenced on the date of such failure to borrow)
over the amount of interest (as reasonably determined by Lender) that could be
realized by  Lender in re-employing during such period the funds so paid,
prepaid or not borrowed. A certificate of Lender setting forth any amount or
amounts which Lender is entitled to receive pursuant to this Section 2.9 shall
be conclusive absent manifest error.

     2.10 CHANGE IN LEGALITY.

     (a) Notwithstanding anything to the contrary herein contained, if any
change in any law or regulation or in the interpretation thereof by any
governmental authority charged with the administration or interpretation
thereof shall make it unlawful for any Lender to make or maintain any LIBOR
Loan or to give effect to its obligations as contemplated hereby (an
"Illegality"), or if  Lender determine that maintenance of LIBOR Loans would
cause it to implement or modify any reserve, special deposit or assessment or
other requirement, or impose any other condition on Lender affecting the
Revolving Loan or the Term Loan not applicable to Lender on the Closing (each
of the foregoing circumstances called a "Regulatory Action"), then, by written
notice to the Borrower, Lender shall:

     (i) declare that LIBOR Loans will not thereafter be made by Lender
hereunder, whereupon the Borrower shall be prohibited from requesting LIBOR
Loans from Lender hereunder unless such declaration is subsequently withdrawn;
provided, however, that if after the date of any such declaration there shall
occur any change in law or regulation or in the interpretation thereof by any
government authority charged with the administration or interpretation thereof
that shall eliminate such Illegality, Lender shall as promptly as reasonably
practicable notify the Borrower of such occurrence and withdraw such
declaration; and

     (ii) require that all outstanding LIBOR Loans made by it be converted
loans at the Reference Rate, in which event all  Loans shall be automatically
converted to loans at the Reference Rate as of the effective date of such
notice as provided in paragraph (b) below.

     (b) For purposes of this Section 2.10, a notice to the Borrower by Lender
pursuant to paragraph (a) above shall be effective on the date of receipt by
the Borrower.

     2.11 UNAVAILABILITY OF DEPOSITS OR INABILITY TO ASCERTAIN, OR INADEQUACY
OF LIBOR RATE. If on or prior to the first day of any Interest Period for any
Borrowing of LIBOR Loans:

     (a) Lender advises the Borrower that deposits in U. S. dollars (in the
applicable amounts) are not being offered to it in the off-shore U.S. dollar
interbank market for such Interest Period, or

                                     15


<PAGE>   16


     (b) Lender determines that the Libor Rate will not adequately and fairly
reflect the cost to such Lender of funding the Loans for such Interest Period,

then the Lender shall forthwith give notice thereof to the Borrower and the
Lender, whereupon until the Lender notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Lender
to make  Loans shall be suspended without liability to Lender.

     2.12 INCREASED COST AND REDUCED RETURN; LIBOR LOANS.  If on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by Lender with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency:

     (a) shall subject Lender to any tax, duty or other charge with respect to
the Revolving Loan Note or the Term Loan Note, or shall change the basis of
taxation of payments to Lender of the principal of or interest on the Loans or
any other amounts due under this Agreement in respect of its Loans or its
obligation to make Loans (except for changes in the rate of tax on the overall
net income of Lender imposed by the jurisdiction in which Lender's principal
executive office); or

     (b) shall impose, modify or deem applicable any reserve, special deposit
or similar requirement (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, against assets
of, deposits with or for the account of, or credit extended by, Lender (or its
Applicable Lending Office) or shall impose on Lender or on the interbank market
any other condition affecting the Revolving Loan Note, the Term Loan Note, or
its obligation to make Loans; and the result of any of the foregoing is to
increase the cost to Lender of making or maintaining any  Loan, or to reduce
the amount of any sum received or receivable by Lender under this Agreement or
under the Revolving Loan Note or the Term Loan Note with respect thereto, by an
amount deemed reasonably and in good faith by Lender to be material, then, if
such Loan is for an Interest Period of more than ninety (90) days, Borrower
shall, within fifteen (15) days after demand by Lender, be obligated to pay
Lender such additional amount or amounts as will compensate lender for such
increased cost or reduction (computed commencing on the effective date of any
event mentioned herein). Lender agrees to use its best efforts to give the
Borrower notice of the occurrence of any event mentioned herein. In addition,
Lender may, upon notice to Borrower, elect to increase the interest rate
applicable to all Loans made subsequent thereto, to compensate Lender for such
increased cost or reduced yield.

     2.13 DISCRETION OF LENDER AS TO MANNER OF FUNDING. Notwithstanding any
other provision of this Agreement, Lender shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if Lender had actually funded and
maintained the Loans through the purchase of deposits in the interbank market
having a maturity 

                                     16


<PAGE>   17


corresponding to each Loan's Interest Period and bearing an interest rate equal 
to the Libor Rate for such interest period.

     2.14 ADJUSTMENTS TO INTEREST RATES.   The LIBOR Rate shall be adjusted as
to the Applicable Margin based on changes in the Total Debt to EBITDA Ratio.
Such adjustments shall be made by the Bank without notice to Borrower, based on
such Ratio as of the end of a Fiscal Quarter. The Applicable Margin shall be
reduced to a specified level only in the event that (A) no Potential Default or
Event of Default exists as of the date of determination and (B) the required
Total Debt to EBITDA Ratio has been satisfied. All adjustments shall be
effective as follows:

     (a) Lender shall make its Applicable Margin determination within 10
Business Days of the receipt by Lender (the "Review Periods) of Borrower's
quarterly or annual financial statements and Compliance Certificate indicating
that an adjustment in the Applicable Margin is warranted;

     (b) any reduction or increase in the Applicable Margin after the Review
Period shall be effective on the first day of the Fiscal Quarter following such
increase or reduction, and

     (c) if any Financial Statements necessary for calculation of the Total
Debt to EBITDA Ratio provided for in this Section 2.14 are not delivered to the
Lender within the time periods specified in Section 8.2, and such statements
when ultimately delivered give rise to an increase or decrease in the
applicable Margin, such increase or decrease shall be retroactive to the date
such Financial Statements were required to be delivered pursuant to Section
8.2.

rule indicating past or present generation, transportation, treatment, storage

Borrower, except as hereinafter provided, Lender may, at its sole election,
without notice of its election and without demand, do any one or more of the
following, all of which are authorized by Borrower:

     (a) Declare all Obligations, whether evidenced by this Agreement, by

Obligations shall be immediately due and payable without notice or demand upon
an Event of Default under Section 10.6 or 10 7;

     (b) Cease advancing money or extending credit to or for the benefit of
Borrower under this Agreement, or any other agreement between Borrower and
