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

     This Amended and Restated Loan and Security Agreement dated June 16, 1997
(the "AGREEMENT"), is entered into by and between SUMMIT BANK, a New Jersey
banking corporation ("LENDER"), successor by merger to United Jersey Bank; CYBEX

                                   BACKGROUND
                                   ----------

     On December 7, 1995, the Lender loaned to Trotter and Trotter Holding two
credit facilities consisting of a revolving loan of the principal sum of
$3,000,000 (the "TROTTER REVOLVING LOAN"), and a term loan in the original
principal amount of $9,000,000 (the "TROTTER TERM LOAN").

     On February 28, 1996, the Lender provided to Trotter, Inc. a third credit
facility in the original principal amount of $3,579,000 as evidenced by a Letter
of Credit and Reimbursement Agreement dated February 1, 1996 (the "TROTTER
LETTER OF CREDIT").  Hereinafter, the Trotter Revolving Loan, Trotter Term Loan
and the Trotter Letter of Credit are collectively called the "TROTTER LOANS".

     As of December 27, 1996, Cybex, Trotter and Cat's Tail, Inc., a Delaware
corporation (the "MERGER SUB") executed an Agreement and Plan of Merger pursuant
to which Merger Sub was merged on May 23, 1997 into Trotter and Trotter became a
wholly-owned subsidiary of Cybex.  Trotter Holding continues to be a wholly-
owned subsidiary of Trotter.

     The Borrowers have requested the Lender to make additional loans to the
Borrowers and to renew, extend and increase the Trotter Loans, but with the

                                       1
<PAGE>
 
Borrowers as the Obligors thereon; and the Lender, subject to and in accordance
with the terms and conditions herein, contained, has agreed to make available to
and lend to the Borrowers, the credit facilities described herein.

     As of June 16, 1997 there was due and owing to the Lender by Trotter and
Trotter Holding for the Trotter Loans, the sum of $14,422,135.67 computed as
follows:

as set forth in the Revolving Note.

          (c) Interest on the Term Loan shall accrue at Borrower's option from
time to time either (i) at the Floating Base Rate or (ii) the LIBOR Based Rate.
In order for a LIBOR Based Rate to apply, Borrowers must have given Lender at
least three Business Days' prior written, telecopier, facsimile or telephonic
(promptly confirmed in writing) notice thereof (herein, a "LIBOR Notice") which
notice shall specify the Interest Period or Interest Periods elected by
Borrowers and the principal amount or amounts to which such LIBOR Notice shall
apply.  Unless a new LIBOR Notice hereunder is given, upon expiration of an
Interest Period with respect to principal under the Term Loan, such principal
amount shall bear interest at the Floating Rate.  The Floating Rate shall apply
at all times to any principal [or portion thereof] not covered by a LIBOR
Notice. A LIBOR Notice as to less than all the principal shall cover at least
$1,000,000.  No LIBOR Notice may be given if the principal covered thereby would
be due prior to expiration of the applicable Interest Period.  Interest shall be
payable

                                       14
<PAGE>
 
quarterly as set forth in the Term Note, except for interest at the
LIBOR Based Rate, which shall be due upon expiration of the applicable Interest
Period.

          (d) Anything in this Agreement or the Notes to the contrary
notwithstanding, the interest rate on the Loans shall in no event be in excess
of the maximum permitted by Applicable Law.

     3.3  FEES.
          ---- 

          (a) Borrowers agree to pay to Lender an origination fee of $70,000.

          (b) Borrowers agree to pay to Lender on the last Business Day of each
March, June, September and December in each year (commencing on the last
Business Day of June, 1997) a commitment fee of one-fourth of one percent
(0.25%) per annum, computed on the basis of the actual number of days elapsed
over a year of 360 days, on the average daily unused amount of the
Lender's commitment under the Revolving Loan Facility.  Such commitment fee
shall accrue from the Closing Date.

          (c) Borrowers agree to pay to Lender on the last business day of each
March, June, September and December in each year (commencing on the last
Business Day of June, 1997) a letter of credit fee of one and one-half percent
(1 1/2%) per annum, computed on the basis of the actual number of days elapsed
over a year of 360 days, on the principal amount of the Trotter Letter of
Credit.  Such fee has continued to accrue from April 1, 1997.
 
     3.4  PREPAYMENT OF LOANS.
          ------------------- 

          In the event that Borrowers intend to prepay the Loans in whole,
whether by refinance or payment through cash reserves, the Borrowers shall give
Lender not less than thirty (30) days' prior written notice of Borrowers'
intention to prepay (which notice shall be irrevocable) and (unless the
refinance of the Loans is accomplished through the Lender) pay to Lender an
additional sum (the "PREPAYMENT CONSIDERATION") equal to:

          (i)  $75,000 if the Loan is prepaid during the year 1997;
and
          (ii) $50,000 if the Loan is prepaid during the year 1998;

                                       15
<PAGE>
 
          Any prepayment will also be accompanied by payment of all accrued and
unpaid interest due to the date of prepayment on the principal amount prepaid
and all other fees, expenses and other sums due and owing under the Loan
Documents.  Any partial prepayment will be applied to installments of principal
due in their inverse order of maturity.  The Prepayment Consideration shall
apply to a voluntary or involuntary prepayment, whether by acceleration of the
Loans upon a default or otherwise.

     5.9  REAFFIRMATION BY BORROWERS OF EXISTING COLLATERAL.  This Agreement
          -------------------------------------------------

Borrowers hereby represent, warrant and reaffirm to the Lender that it is the
intention that all existing collateral security held by the Lender shall
continue to serve as Collateral for the Loans and any other liabilities due the
Lender by the Borrowers and until the Loans are paid in full, the security
interests and mortgages held by the Lender shall otherwise continue in full
force and legal effect.

SECTION 6.  COLLECTION AND ADMINISTRATION
            -----------------------------

     6.1  BORROWERS' LOAN ACCOUNT.  Lender shall maintain one or more loan
          -----------------------                                         
account(s) on its books in which shall be recorded (a) all Loans and other
Obligations and the Collateral, (b) all payments made by or on behalf of
Borrowers and (c) all other appropriate debits and credits as provided in this
Agreement, including, without limitation, fees, charges, costs, expenses and
interest.  All entries in the loan account(s) shall be made in accordance with
Lender's customary practices as in effect from time to time.

     6.2  STATEMENTS.  Lender shall render to Borrowers each month a statement
          ----------                                                          
setting forth the balance in the Borrowers' loan account(s) maintained by Lender
for Borrowers pursuant to the provisions of this Agreement, including principal,
interest, fees, costs and expenses.  Each such statement shall be subject to
subsequent adjustment by Lender but shall, absent manifest errors or omissions,
be considered correct and deemed accepted by Borrowers and conclusively binding
upon Borrowers as an account stated except to the extent that Lender receives a
written notice

                                       20
<PAGE>
 
from Borrowers of any specific exceptions of Borrowers thereto within thirty
(30) days after the date such statement has been mailed by Lender. Until such
time as Lender shall have rendered to Borrowers a written statement as provided
above, the balance in Borrowers' loan account(s) shall be presumptive evidence
of the amounts due and owing to Lender by Borrowers.

     6.3  PAYMENTS.  All Obligations shall be payable at Lender's office or as
          --------                                                            
Lender may designate from time to time.  Lender may apply payments received or
collected from Borrowers or for the account of Borrowers (including, without
limitation, the monetary proceeds of collections or of realization upon any
Collateral) to such of the Obligations, whether or not then due, in such order
and manner as Lender determines.  At Lender's option, all principal, interest,
fees, costs, expenses and other charges provided for in this Agreement or the
other Financing Agreements may be charged directly to the loan account(s) of
Borrowers.  Borrowers shall make all payments to Lender on the Obligations free
and clear of, and without deduction or withholding for or on account of, any
set-off, counterclaim, defense, duties, taxes, levies, posts, fees, deductions,
withholding, restrictions or conditions of any kind. If after receipt of any
payment of, or proceeds of Collateral applied to the payment of, any of the
Obligations, Lender is required to surrender or return such payment or proceeds
to any Person for any reason, then the Obligations intended to be satisfied by
such payment or proceeds shall be reinstated and continue and this Agreement
shall continue in full force and effect as if such payment or proceeds had not
been received by Lender. Borrowers shall be liable to pay to Lender, and do
hereby indemnify and hold Lender harmless for the amount of any payments or
proceeds surrendered or returned. This Section 6.3 shall remain effective

upon such payment or proceeds. This Section 6.3 shall survive the payment of the
Obligations and the termination or nonrenewal of this Agreement.

     6.4  AUTHORIZATION TO MAKE LOANS.  Lender is authorized to make the Loans
          ---------------------------

be an officer of Borrowers or other authorized person who is listed on a list of
authorized officers provided to Lender, provided that the Borrower shall confirm
any telephonic messages by a writing signed by an authorized officer of the
Borrower.  All requests for Loans hereunder shall specify the

                                       21
<PAGE>
 
date on which the requested advance is to be made (which day shall be a business
day) and the amount of the requested Loan. Requests received after 11:00 a.m.
Eastern time on any day shall be deemed to have been made as of the opening of
business on the immediately following business day. All Loans under this
Agreement shall be conclusively presumed to have been made to, and at the
request of and for the benefit of, Borrowers when deposited to the credit of
Borrowers or otherwise disbursed or established in accordance with the
instructions of Borrowers or in accordance with the terms and conditions of this
Agreement.

     6.5  USE OF PROCEEDS.  Borrowers shall use the proceeds of the Loans
          ---------------                                                
provided by Lender to Borrowers hereunder only for the following purposes: (a)
merger costs incurred in the merger of Merger Sub with Trotter, severance

loan due by Cybex and the mortgage loan on the Ronkonkoma real estate; and (d)
costs, expenses and fees in connection with the preparation, negotiation,
execution and delivery of this Agreement and the other Financing Agreements.
None of the proceeds will be used, directly or indirectly, for the purpose of
purchasing or carrying any margin security or for the purposes of reducing or
retiring any indebtedness which was originally incurred to purchase or carry any
margin security or for any other purpose which might cause any of the Loans to
be considered a "purpose credit" within the meaning of Regulation U of the Board
of Governors of the Federal Reserve System, as amended.

not, by doing so, be deemed to have assumed any obligation or liability of
Borrowers.  Any payment made or other action taken by Lender

personal property located at the Borrower's facility in Ronkonkoma, New York.

Ronkonkoma facility. In the event that the facility is not sold within six (6)

warrant that Norwest Bank Minnesota South N.A. has agreed to limit the lien of
the prior filing to personal property, fixtures and equipment located on the
premises as of the date of the execution of this Agreement and said lien shall
not attach to any additions or substitutions of the Owatonna Collateral.

SECTION 8. REPRESENTATIONS AND WARRANTIES
           ------------------------------

          Borrowers hereby represent and warrant to Lender the following (which
shall survive the execution and delivery of this Agreement), the truth and
accuracy of which are a continuing condition of the making of Loans by Lender to
Borrowers:

     8.1  CORPORATE EXISTENCE, POWER AND AUTHORITY: SUBSIDIARIES. Each Borrower
          ------------------------------------------------------               
is a corporation duly organized and in good standing under the laws of its state
of incorporation and is duly qualified as a foreign corporation and in good
standing in all states or other jurisdictions where the nature and extent of the
business transacted by it or the ownership of assets makes such qualification
necessary, except for those jurisdictions in which the failure to so qualify
would not have a material adverse effect on each Borrower's financial condition,
results of operation or business or the rights of Lender in or to any of the
Collateral. The execution, delivery and performance of this Agreement, the other
Financing Agreements and the transactions contemplated hereunder and thereunder
are all within Borrowers' corporate powers, have been duly authorized and are
not in contravention of

                                       29
<PAGE>
 
law or the terms of each Borrower's certificate of incorporation, bylaws, or
other organizational documentation, or any indenture, agreement or undertaking
to which each Borrower is a party or by which each Borrower or its property are
bound. This Agreement and the other Financing Agreements constitute legal, valid
and binding obligations of each Borrower enforceable in accordance with their
respective terms. Trotter does not have any subsidiaries except for Trotter
Holding, and Trotter Holding owns no assets except for the trademarks and/or
tradenames listed on the attached information sheet.

     8.2  FINANCIAL STATEMENTS; NO MATERIAL ADVERSE CHANGE.  All financial
          ------------------------------------------------                
statements relating to Borrowers which have been or may hereafter be delivered
by Borrowers to Lender have been prepared in accordance with GAAP and fairly
present the financial condition and the results of operation of Borrowers as at
the dates and for the periods set forth therein.  Except as disclosed in any
interim financial statements furnished by Borrowers to Lender prior to the date
of this Agreement, there has been no material adverse change in the assets,
liabilities, properties and condition, financial or otherwise, of Borrowers
since the date of the most recent audited financial statements furnished by
Borrowers to Lender prior to the date of this Agreement.

     8.3  CHIEF EXECUTIVE OFFICE; COLLATERAL LOCATIONS.  The chief executive
          --------------------------------------------                      
office of Borrowers and Borrowers' Records concerning Accounts are located only
at 10 Trotter Drive, Medway, Massachusetts and its other places of business and
the only other locations of Collateral, if any, are the addresses set forth in
the Information Certificate, subject to the right of Borrowers to establish new
locations in accordance with Section 9.2 below. The Information Certificate
correctly identifies any of such locations which are not owned by Borrowers and
sets forth the owners and/or operators thereof and, to the best of Borrowers'
knowledge, the holders of any mortgages on such locations.

     8.4  PRIORITY OF LIENS; TITLE TO PROPERTIES.  The security interests,
          --------------------------------------                          
mortgages and liens granted to Lender under this Agreement and the other
Financing Agreements constitute valid and perfected first priority liens and
security interests in and upon the Collateral subject only to the liens
indicated on Schedule 8.4 hereto and the other liens permitted under Section 9.8
hereof (it being understood that unless Lender otherwise requests, Borrowers

                                       30
<PAGE>
 
will not be required to perfect the liens on property owned by Lumex, Cybex
Fitness or General Medical, provided, however, that in the event that the Loans
remain outstanding for a period of six (6) months from the date of execution any
and all documents necessary to grant a perfected first lien security interest on
the property owned by Lumex, Cybex Fitness or General Medical, if such company
is still in existence. Borrowers have good and marketable title to all of their
properties and assets subject to no liens, mortgages, pledges, security
interests, encumbrances or charges of any kind, except those granted to Lender
and such others as are specifically listed on Schedule 8.4 hereto or permitted
under Section 9.8 hereof.

     8.5  TAX RETURNS.  Each Borrower has filed, or caused to be filed, in a

timely manner all tax returns, reports and declarations which are required to be
filed by it (without requests for extension, except as previously disclosed in
writing to Lender) the failure of which to file would result in material adverse
consequences to the Borrowers as a whole or would jeopardize or result in a lien
on any of the Collateral.  All information in such tax returns, reports and
declarations is complete and accurate in all material respects.  Each Borrower
has paid or caused to be paid all taxes due and payable or claimed due and
payable in any assessment received by it, except taxes the validity of which are
being contested in good faith by appropriate proceedings diligently pursued and
available to each Borrower and with respect to which adequate reserves have been
set aside on its books.  Adequate provision has been made for the payment of all
accrued and unpaid Federal, State, county, local, foreign and other taxes
whether or not yet due and payable and whether or not disputed.

     8.6  LITIGATION.  Except as set forth on the Information Certificate, there
          ----------                                                            
is no present investigation by any governmental agency pending, or to the best
of Borrowers' knowledge threatened, against or affecting any Borrower, its
assets or business and there is no action, suit, proceeding or claim by any
Person pending, or to the best of Borrowers' knowledge threatened, against
Borrowers or their assets or goodwill, or against or affecting any transactions
contemplated by this Agreement, which if adversely determined against such
Borrowers would result in any material adverse change in the assets, business or
prospects of Borrowers or would impair the ability of Borrowers to perform their
obligations hereunder or under any of the other Financing Agreements to which

                                       31

any Collateral.

or they are or any of its or their assets are bound and Borrowers are in

Borrowers and that are necessary or useful in the operation of their business.

     8.8  ACCURACY AND COMPLETENESS OF INFORMATION.  All information furnished

contemplated hereby or thereby, including without limitation, all information on
the Information Certificate is true and correct in all material respects on the
date as of which such information is dated or certified and does not omit any
material fact necessary in order to make such information not misleading.  No

writing.

          (j) any substantial change in management of Cybex, whether by reason
of death, resignation, protractive illness, change of ownership or employment or
management policies or for any other reason, Cybex shall give prompt written
notice thereof to the Lender and Lender, whether or not so notified upon being
informed of such change may, if not reasonably satisfied with the new
management, require that same be revised or reformed in the manner satisfactory
to the Lender;

          (k) the indictment of a Borrower or any Obligor under any criminal

          (l) there shall be an event of default under any of the other

     10.2 REMEDIES.
          -------- 

          (a) At any time an Event of Default exists or has occurred and is
continuing, Lender shall have all rights and remedies provided in this
Agreement, the other Financing Agreements, the Uniform Commercial Code and other
applicable law, all of which rights and remedies may be exercised without notice
to or consent by Borrowers or any Obligor, except as such notice or consent is
expressly provided for hereunder or required by applicable law. All rights,
remedies and powers granted to Lender hereunder, under any of the other
Financing Agreements, the Uniform Commercial Code or other applicable law, are
cumulative, not exclusive and enforceable, in Lender's discretion,
alternatively, successively, or concurrently on any one or more occasions, and
shall include, without limitation, the right to apply to a court of equity for
an injunction to restrain a breach or threatened breach by a Borrower of this
Agreement or any of the other Financing Agreements.  Lender may, at any time or
times, proceed directly

                                       48
<PAGE>
 
against Borrowers or any Obligor to collect the Obligations without prior
recourse to the Collateral.

     Without limiting the foregoing, at any time an Event of Default exists or
has occurred and is continuing, Lender may, in its discretion and without
limitation, (i) accelerate the payment of all Obligations and demand immediate
payment thereof to Lender (provided, that, upon the occurrence of any Event of
                          ----------------                                    
Default described in Sections 10.1(g) and 10.1(h), all Obligations shall
automatically become immediately due and payable), (ii) with or without judicial
process or the aid or assistance of others, enter upon any premises on or in
which any of the Collateral may be located and take possession of the Collateral
or complete processing, manufacturing and repair of all or any portion of the
Collateral, (iii) require Borrowers, at Borrowers' expense, to assemble and make
available to Lender any part or all of the Collateral at any place and time
designated by Lender, (iv) collect, foreclose, receive, appropriate, set-off and
realize upon any and all Collateral, (v) remove any or all of the Collateral
from any premises on or in which the same may be located for the purpose of
effecting the sale, foreclosure or other disposition thereof or for any other
purpose, (vi) sell, lease, transfer, assign, deliver or otherwise dispose of any
and all Collateral (including, without limitation, entering into contracts with
respect thereto, public or private sales at any exchange, broker's board, at any
office of Lender or elsewhere) at such prices or terms as Lender may deem
reasonable, for cash, upon credit or for future delivery, with the Lender having
the right to purchase the whole or any part of the Collateral at any such public
sale, all of the foregoing being free from any right or equity of redemption of
Borrowers, which right or equity of redemption is hereby expressly waived and
released by Borrowers and/or (vii) terminate this Agreement. If any of the
Collateral is sold or leased by Lender upon credit terms or for future delivery,
the Obligations shall not be reduced as a result thereof until payment therefor
is finally collected by Lender. If notice of disposition of Collateral is
required by law, five (5) days' prior notice by Lender to Borrowers designating
the time and place of any public sale or the time after which any private sale
or other intended disposition of Collateral is to be made, shall be deemed to be
reasonable notice thereof and Borrowers waive any other notice. In the event
Lender institutes an action to recover any Collateral or seeks recovery of any

                                       49
<PAGE>
 
Collateral by way of prejudgment remedy, Borrowers waive the posting of any bond
which might otherwise be require.

          (b) Lender may apply the cash proceeds of Collateral actually received
by Lender from any sale, lease, foreclosure or other disposition of the
Collateral to payment of the Obligations, in whole or in part and in such order
as Lender may elect, whether or not then due.  Borrowers shall remain liable to
Lender for the payment of any deficiency with interest at the highest rate
provided for herein and all costs and expenses of collection or enforcement,
including attorneys' fees and legal expenses.

          (c) Without limiting the foregoing, upon the occurrence of an Event of
Default or an event which with notice or passage of time or both would
constitute an Event of Default, Lender may, at its option, without notice, (i)
cease making Loans or reduce the lending formulas or amounts of Revolving Loans
available to Borrower and/or (ii) terminate any provision of this Agreement
providing for any future Loans to be made by Lender to Borrowers.

SECTION 11.    JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS;
               GOVERNING LAW
               ---------------------------------------------

     11.1 GOVERNING LAW; CHOICE OF FORUM; SERVICE OF PROCESS; JURY TRIAL WAIVER.
          ----------------------------------------------------------------------

          (a) The validity, interpretation and enforcement of this Agreement and
the other Financing Agreements and any dispute arising out of the relationship
between the parties hereto, whether in contract, tort, equity or otherwise,
shall be governed by the internal laws of the State of New Jersey (without
giving effect to principles of conflicts of law).

          (b) Borrowers and Lender irrevocably consent and submit to the non-
exclusive jurisdiction of the Superior Court of the State of New Jersey and the
United States District Court for the District of New Jersey and waive any
objection based on venue or forum non conveniens with respect to any action
                            --------------------                           
instituted therein arising under this Agreement or any of the other Financing
Agreements or in any way connected with or related or incidental to the dealings
of the parties hereto in respect of this Agreement or any of the other Financing
Agreements or the transactions related hereto or thereto, in each case whether
now existing or hereafter

                                       50
<PAGE>
 
arising, and whether in contract, tort, equity or otherwise, and agree that any
dispute with respect to any such matters shall be heard only in the courts
described above (except that Lender shall have the right to bring any action or
proceeding against a Borrower or its property in the courts of any other
jurisdiction which Lender deems necessary or appropriate in order to realize on
the Collateral or to otherwise enforce its rights against a Borrower or its
property).

          (c) Each Borrower hereby waives personal service of any and all
process upon it and consents that all such service of process may be made by
certified mail (return receipt requested) directed to its address set forth on
the signature pages hereof and service so made shall be deemed to be completed
five (5) days after the same shall have been so deposited in the U.S. mails, or,
at Lender's option, by service upon Borrower in any other manner provided under
the rules of any such courts. Within thirty (30) days after such service,
Borrower shall appear in answer to such process, failing which Borrower shall be
deemed in default and judgment may be entered by Lender against Borrower for the
amount of the claim and other relief requested.

          (d) BORROWERS AND LENDER EACH HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT
OR ANY OF THE OTHER FINANCING AGREEMENTS OR (II) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS
AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR THE TRANSACTIONS RELATED
HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND
WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. BORROWERS AND LENDER EACH HEREBY
AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL
BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT BORROWERS OR LENDER MAY FILE
AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

          (e) Lender shall not have any liability to a Borrower (whether in
tort, contract, equity or otherwise) for losses suffered by a Borrower in
connection with, arising out of, or in any way related to the transactions or
relationships contemplated by this Agreement, or any act, omission or event
occurring in connection herewith, unless it is determined by a final and

                                       51
<PAGE>
 
nonappealable judgment or court order binding on Lender, that the losses were
the result of acts or omissions constituting gross negligence or willful
misconduct.  In any such litigation, Lender shall be entitled to the benefit of
the rebuttable presumption that it acted in good faith and with the exercise of
ordinary care in the performance by it of the terms of this Agreement.

     11.2 WAIVER OF NOTICES.  Borrowers hereby expressly waive demand,
          -----------------                                           
presentment, protest and notice of protest and notice of dishonor with respect
to any and all instruments and commercial paper, included in or evidencing any
of the Obligations or the Collateral, and any and all other demands and notices
of any kind or nature whatsoever with respect to the Obligations, the Collateral
and this Agreement, except such as are expressly provided for herein.  No notice
to or demand on a Borrower which Lender may elect to give shall entitle a
Borrower to any other or further notice or demand in the same, similar or other
circumstances.

     11.3 AMENDMENTS AND WAIVERS. Neither this Agreement nor any provision
          ----------------------                                          
hereof shall be amended, modified, waived or discharged orally or by course of
conduct, but only by a written agreement signed by an authorized officer of
Lender.  Lender shall not, by any act, delay, omission or otherwise be deemed to
have expressly or impliedly waived any of its rights, powers and/or remedies
unless such waiver shall be in writing and signed by an authorized officer of
Lender. Any such waiver shall be enforceable only to the extent specifically set
forth therein.  A waiver by Lender of any right, power and/or remedy on any one
occasion shall not be construed as a bar to or waiver of any such right, power
and/or remedy which Lender would otherwise have on any future occasion, whether
similar in kind or otherwise.

     11.4 WAIVER OF COUNTERCLAIMS.  Each Borrower waives all rights to interpose
          -----------------------                                               
any claims, deductions, set-offs or counterclaims of any nature (other then
compulsory counterclaims) in any action or proceeding with respect to this
Agreement, the Obligations, the Collateral or any matter arising therefrom or
relating hereto or thereto.

     11.5 INDEMNIFICATION.  Borrowers shall indemnify and hold Lender, and its
          ---------------                                                     
directors, agents, employees and counsel, harmless from and against any and all
losses, claims, damages, liabilities,

                                       52
<PAGE>
 
costs or expenses imposed on, incurred by or asserted against any of them in
connection with any litigation, investigation, claim or proceeding commenced or
threatened related to the negotiation, preparation, execution, delivery,
enforcement, performance or administration of this Agreement, any other
Financing Agreements, or any undertaking or proceeding related to any of the
actions contemplated hereby or any act, omission, event or transaction related
or attendant thereto, including, without limitation, amounts paid in settlement,
court costs, and the fees and expenses of counsel. To the extent that the
undertaking to indemnify, pay and hold harmless set forth in this Section may be
unenforceable because it violates any law or public policy, Borrower shall pay
the maximum portion which it is permitted to pay under applicable law to Lender
in satisfaction of indemnified matters under this Section. The foregoing
indemnity shall survive the payment of the Obligations and the termination or
nonrenewal of this Agreement.
