Technologies, Holdings and the Registrant or any of the Registrant's affiliates,

                           rent, tenant allowances and security deposits
                           thereunder and all leasehold improvements owned by
                           SST and forming part of the leased Real Property.

2.2      EXCLUDED ASSETS AND EXCLUDED CONTRACTS: For the sake of clarity, the
         parties acknowledge and agree that SST shall not sell, and WC shall
         not purchase the assets listed on Schedule 2.2A (collectively the
         "Excluded Assets") and WC shall not assume any of the contracts listed
         on Schedule 2.2B (collectively the "Excluded Contracts") nor any of
         the obligations or liabilities relating thereto.

2.3      PURCHASE PRICE:

         The purchase price for the Purchased Assets (the "Purchase Price")
shall be approximately $51,491,342.00. The foregoing estimate is based upon a
price of $51,399,122.00 for the Purchased Assets as at March 31, 1998 plus a net
adjustment of $92,220.00 for additions, deletions and accrued depreciation for
the period April 1, 1998 to and including the Effective Date.

2.4      PAYMENT OF THE PURCHASE PRICE:

         The Purchase Price will be paid at the time of Closing:

(1)               by the issuance of Woodhead Shares. SST and WC have agreed
                  that, as part of the Purchase Price, SST will receive 400,000
                  Woodhead Shares. In order to determine the subscription amount
                  for each Woodhead Share (the "Subscription Price"), the
                  Parties have agreed on the following formula:

                  1.       The daily volume weighted average of the trading
                           price for a share of Woodhead common stock as
                           reported on the Nasdaq National Market (as reported
                           in the Wall Street Journal, Midwest edition) for the
                           most recent fifteen (15) days that such shares have
                           traded ending on the trading day two (2) days prior
                           to the Closing Date will be determined (the "Average
                           Trading Price");

                  2.       Once such Average Trading Price is determined and
                           provided such trading price is not greater than US
                           $22.00 (the "Upper Limit") or less than US $15.00
                           (the "Lower Limit"), then such Average Trading Price
                           shall be the


<PAGE>


                                      -15-

                           Subscription Price for the purpose of establishing
                           how much of the Purchase Price is represented by the
                           subscription for the 400,000 Woodhead Shares;

                  3.       If the Average Trading Price exceeds the Upper Limit,
                           SST may, but is not required to, terminate this
                           agreement unless WC elects to accept the Upper Limit
                           as the Subscription Price by adjusting the cash
                           component of the Purchase Price accordingly;

                  4.       If the Average Trading Price is less than the Lower
                           Limit, then WC may, but is not required to, terminate
                           this agreement unless SST elects to accept the Lower
                           Limit as the Subscription Price by adjusting the cash
                           component of the Purchase Price accordingly.

         (2)      the balance of the Purchase Price will be paid by certified 
                  cheque or bank wire transfer.

2.4.2    ALLOCATION OF PURCHASE PRICE: WC and SST shall allocate the Purchase 
         Price to the Purchased Assets based on their fair market value and as
         provided on Schedule 2.4. WC and SST agree to co-operate post-Closing
         to further allocate the Purchase Price against the Purchased Assets
         for the purposes of calculating any provincial sales Taxes on the same.

2.5      TIME AND PLACE OF CLOSING: The completion of the purchase and sale of 
         the Purchased Assets contemplated by this Agreement (the "Closing") 
         shall take place at the offices of WC's Solicitors at the Time of
         Closing on the Closing Date.

2.6      NON-ASSIGNABLE CONTRACTS: This Agreement and any document delivered
         hereunder shall not constitute an assignment or an attempted assignment
         of any Contract or Realty Lease contemplated to be assigned to WC 
         hereunder and not assignable without the consent of a third party if
         such consent has not been obtained and such assignment or attempted 
         assignment would constitute a breach thereof. To the extent that any of
         the foregoing items (e.g. Allen Bradley) are not assignable by the 
         terms thereof or where consents to the assignment thereof cannot be
         obtained for Closing as herein provided, then in the event this
         Agreement contemplates that such consent will not be obtained or WC 
         waives any such consent as a condition of Closing and this transaction
         closes, such items shall be held by SST in trust for WC and the
         covenants and obligations thereunder shall be performed by WC in the
         name of SST and all benefits and obligations existing thereunder shall
         be for the account of WC. SST shall take or cause to be taken such 
         action in its name or otherwise as WC may reasonably require so as to
         provide WC with the benefits thereof. Upon Closing, SST authorizes WC,
         at WC's expense, to perform all of SST's obligations under the 
         foregoing items.

             expropriated or otherwise taken by any public authority and SST 
             does not know nor does it have any grounds to believe that any 
             such condemnation, requisition, expropriation or taking is 
             threatened or contemplated.

             the operation of the Business in the Ordinary Course and,
             specifically:

                           passed; and;

                  (3)      there is nothing owing by SST in respect of the Real
                           Property to any municipal corporation, or to any
                           other corporation or commission owning or operating a
                           public utility for water, gas, electrical power or

                           or for the use thereof, other than current accounts
                           in respect of which the due date has not yet passed
                           and any immaterial amounts subject to bona fide 
                           dispute.

         (7) Work Orders and Deficiencies: There are no outstanding work
             orders, non-compliance orders, deficiency notices or other
             such notices verbal or written relevant to the Real Property,
             the other Purchased Assets or the Business which have been
             issued by any police or fire department, sanitation,
             environment, labour, health or other Governmental Authority.
             There are no matters under discussion with any such department
             or authority relating to work orders, non-compliance orders,
             deficiency notices or other such notices.

         (8) Plants, Facilities and Equipment: To the best of SST's knowledge,
             the buildings, fixtures and structures comprising the Real 
             Property are free of any structural defect having regard to the

             ventilating, plumbing, drainage, electrical and air conditioning
             systems and all other systems used in the Real Property leased by
             SST and all machinery, equipment, tools, furniture, furnishings

             completely within the boundaries of the Real Property save and 
             except for deficiencies in this regard that will not have a 
             Material Adverse Effect on the ability to grant a security interest

         twelve month period (whether by compliance with Rule 144, Regulation S,
         or otherwise) without the need for compliance with the registration
         provisions of the Securities Act or (ii) if Woodhead reasonably
         determines that such registration would be inadvisable due to market or
         other conditions.

         participation or consent of SST and any such actions taken by WC 
         hereunder shall not in any way reduce or limit in any way SST's 
         obligations to indemnify WC in respect thereof all as hereinbefore 
         provided;

                                      -52-

8.4.5    if SST at any time fails to resist and defend diligently and reasonably
         any Claim pursuant to this Section 8.4, its right to defend the Claim
         shall terminate at the option of WC. WC may assume the defence of
         such Claim and may resist, defend, compromise or settle such Claim
         without the participation or consent of SST and any such actions
         taken by WC hereunder shall not in any way reduce or limit in any way
         SST's obligations to indemnify WC in respect thereof all as
         hereinbefore provided.

8.4.6    in the event that SST does deliver a Defence Notice and thereby elects
         to conduct the defence of the subject claim, WC will cooperate with
         and make available to SST such assistance and materials as SST may
         reasonably request, all at the expense of SST, and WC shall have the
         right at its expense to participate in the defense assisted by
         counsel of its own choosing, provided that SST shall have the right
         to compromise and settle the claim only with the prior written
         consent of WC, which consent shall not be unreasonably withheld or
         delayed.

8.4.7    without the prior written consent of WC, SST will not enter into any
         settlement of any third party Claim or cease to defend against such
         Claim, if pursuant to or as a result of such settlement or cessation,
         (i) injunctive or other equitable relief would be imposed against WC,
         or (ii) such settlement or cessation would lead to liability or
         create any financial or other obligation on the part of WC.

8.4.8    SST shall not be entitled to control, and WC shall be entitled to have
         sole control over, the defense or settlement of any claim to the
         extent that claim seeks an order, injunction or other equitable
         relief against WC which, if successful, could materially interfere
         with the business, operations, assets, condition (financial or
         otherwise) or prospective of WC (and the cost of such defense shall
         constitute an amount for which WC is entitled to indemnification
         hereunder).

8.4.9    if an offer is made to settle a third party Claim, which offer SST is
         permitted to settle under this Section 9.4, and SST desires to accept
         and agree to such offer, SST will give written notice to WC to that
         effect. If WC fails to consent to such offer within 15 calendar days
         after its receipt of such notice, WC may continue to contest or
         defend such third party Claim and, in such event, the maximum
         liability of SST as to such third party Claim will not exceed the
         amount of such settlement offer, plus costs and expenses paid or
         incurred by WC through the end of such 15 day period.

8.4.10   any judgment entered or settlement agreed upon in the manner provided
         herein shall be binding upon SST, and shall conclusively be deemed to
         be an obligation with respect to which WC is entitled to prompt
         indemnification hereunder.

8.5      COOPERATION OF WC: During the period that SST is entitled to defend any
         Claim pursuant to section 9.4, WC shall (but at the expense of SST) 
         cooperate with SST in connection with the defence of such Claim and 
         shall provide SST with access to and copies of all relevant books and
         records relating to such Claim provided that if WC re-assumes the
         defence of such Claim as provided in subsection 9.4.5, all such 
         information and material shall be forthwith returned to WC.

8.6      GUARANTEES: Woodhead hereby unconditionally guarantees WC's performance
         of its obligations as primary obligor and not as a guarantor pursuant
         to this Agreement and each ancillary agreement related thereto. SST's
         Guarantor hereby unconditionally guarantees SST's performance of its
         obligations as primary obligor and not as a guarantor pursuant to
         this Agreement and each ancillary agreement related thereto.

Securities Act of 1933 (the "Act") of the Woodhead Shares received by you as
part of the Purchase Price under the Agreement. Woodhead agrees that it will
take such further action as you may reasonably request, all to the extent
required from time to time to enable you to sell such Woodhead Shares commencing
August 1, 1999 without registration under the Act within the volume limitations
and other requirements of the exemption provided by Rule 144. The volume
limitations provide for the sale during any three month period of up to 1% of
the outstanding shares of the class outstanding as reported by the issuer. Based
on the total number of Woodhead Shares outstanding on the date hereof, the
volume limitations of Rule 144 would allow for the sale of no less than 100,000
shares in the aggregate held by SST subject to the requirements of Rule 144
during any three month period commencing after August 1, 1999.


b) Woodhead will prepare and file with the Securities and Exchange Commission
("SEC") as soon as reasonably possible after your written request, provided that
such a request must be received on or after August 1, 1999 but prior to May 1,
2000, a Registration Statement on Form S-3, or other available form of
Registration Statement with respect to the Woodhead Shares received by you as
part of the Purchase Price under the Agreement (hereinafter referred to as the
ARegistration Statement@) and use its reasonable best efforts to cause such
Registration Statement to become effective as soon as reasonably possible
thereafter, and, subject to the provisions below, use its reasonable best
efforts to keep such Registration Statement effective for a period concluding on
the earlier of (i) 90 days after it becomes effective or (ii) until you have
sold all of such Woodhead Shares. If at any time after a Registration Statement
becomes effective, Woodhead advises you in


<PAGE>


writing that due to the existence of material information that has not been
disclosed to the public and included in the Registration Statement it is
necessary to amend the Registration Statement, you shall suspend any
further sale of Woodhead Shares pursuant to the Registration Statement
until Woodhead advises you that the Registration Statement has been
amended. In such event, Woodhead shall not be required to amend the
Registration Statement during any time when the Woodhead=s officers and
directors are prohibited from buying or selling Woodhead Shares pursuant to
Woodhead=s insider trading policy. Notwithstanding the foregoing sentence,
Woodhead shall file any amendment necessary for you to recommence sales
under the Registration Statement concurrently with the commencement of any
period in which directors and officers of Woodhead are allowed to buy or
sell Woodhead Shares pursuant to Woodhead=s insider trading policy.

In addition, Woodhead may suspend use of the Registration Statement to the
extent Woodhead is advised by its legal counsel that such action is reasonably
necessary to comply with federal securities law. In the event the sales of your
Woodhead Shares pursuant to the Registration Statement are suspended as provided
above, the 90-day period during which a Registration Statement must be kept
effective shall be extended for the total number of days during which sales are
suspended. It shall be a condition precedent to the obligations of Woodhead to
take any action pursuant to this section b that you furnish to Woodhead such
information regarding you, the Woodhead Shares held by you, and the intended
method of disposition of such Woodhead Shares, as shall be required to effect
their registration.

c) Notwithstanding the foregoing section (b), Woodhead will not be required to
prepare and file a Registration Statement in the event that an alternative plan
of liquidity which is satisfactory to you, acting reasonably, can be provided to
you.

Yours truly,

WOODHEAD INDUSTRIES INC.

                            Dated as of July 30, 1998

         This CREDIT AGREEMENT dated as of July 30, 1998 (this "Agreement") is
between WOODHEAD CANADA LIMITED (the "Company") and HARRIS TRUST AND SAVINGS

defined.

                              W I T N E S S E T H:

         WHEREAS, the Company has requested the Bank to extend certain loans to
the Company from time to time; and

         WHEREAS, the Bank is willing to extend such loans on the terms and 
subject to the conditions set forth herein;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein contained, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

         SECTION 1 COMMITMENT OF THE BANK; TYPES OF LOANS; BORROWING, 
                   CONTINUATION AND CONVERSION PROCEDURES

         SECTION 1.1 COMMITMENT.  Subject to the terms and conditions of this
Agreement, the Bank agrees to make loans to the Company on a revolving
basis (collectively the "Loans" and each individually a "Loan") from time to
time before the Termination Date in such amounts as the Company may from time to
time request; PROVIDED that the aggregate principal amount of all Loans shall
not at any time exceed $35,000,000 (less any reduction to the amount of the
Commitment made pursuant to SECTION 5.1).

         SECTION 1.2. Each Loan shall be a Domestic Rate Loan, a LIBOR Loan or 
an Offered Rate Loan as the Company shall specify in the related notice of 
borrowing, Continuation or Conversion pursuant to SECTION 1.3 or 1.4. The Bank
shall have no obligation, however, to quote Offered Rates or to make or 
continue, or to Convert any Loan into, an Offered Rate Loan, even after the 
Company has requested an Offered Rate Loan in a notice of borrowing,
Continuation or Conversion pursuant to SECTION 1.3 or 1.4. Domestic Rate Loans,
LIBOR Loans and Offered Rate Loans may be outstanding at the same time, it being
understood, however, that in the case of LIBOR Loans, not more than three 
different Interest Periods shall be outstanding at any time for all LIBOR Loans.

         SECTION 1.3 BORROWING PROCEDURES. The Company shall give written or 
telephonic notice to the Bank of each proposed borrowing (i) prior to 11:00 A.M.

LIBOR Loans and (ii) prior to 11:00 A.M. (Chicago time) on the requested date of
such borrowing, in the case of Offered Rate Loans and Domestic Rate Loans),
specifying:

                  (A) the amount of the such borrowing, which shall be a minimum
         amount of $1,000,000 in the case of LIBOR Loans, a minimum amount of
         $500,000 in the case of Offered Rate Loans, and a minimum amount of
         $100,000 in the case of Domestic Rate Loans; PROVIDED that if such
         requested borrowing is to be a Domestic Rate Loan and the unused amount
         of the Commitment is less than $100,000, the amount of such borrowing
         may be in an amount equal to the unused amount of the Commitment;

                  (B) the requested borrowing date, which shall be a Business
         Day;

                  (C) the Type of Loans comprising such borrowing; and

                  (D) in the case of LIBOR Loans and Offered Rate Loans, the
         duration of the initial Interest Period therefor.

         SECTION 1.4 CONVERSION AND CONTINUATION PROCEDURES.(a) Subject to the 
provisions of SECTION 1.2, the Company may:

                           (i) elect to Convert, on any Business Day, any
                  Domestic Rate Loan (or any part thereof in a minimum amount of
                  $1,000,000 in the case of the Conversion into a LIBOR Loan and
                  $500,000 in the case of the Conversion into an Offered Rate
                  Loan) into a LIBOR Loan or an Offered Rate Loan;

                           (ii) elect to Convert, on the last day of the
                  applicable Interest Period, any LIBOR Loan (or any part
                  thereof in a minimum amount of $100,000 in the case of the
                  Conversion into a Domestic Rate Loan and $500,000 in the case
                  of the Conversion into an Offered Rate Loan) into a Domestic
                  Rate Loan or an Offered Rate Loan (provided that no conversion
                  of a part of a LIBOR Loan to a Domestic Rate Loan or an
                  Offered Rate Loan shall be permitted if the remaining LIBOR
                  Loan would be less than $1,000,000); or

                           (iii) elect to Convert, on the last day of the
                  applicable Interest Period, any Offered Rate Loan (or any part
                  thereof in a minimum amount of $100,000 in the case of the
                  Conversion into a Domestic Rate Loan and $1,000,000 in the
                  case of the Conversion into a LIBOR Loan) into a Domestic Rate
                  Loan or a LIBOR Loan (provided that no conversion of a part of
                  an Offered Rate Loan to a Domestic Rate Loan or a LIBOR Loan
                  shall be permitted if the remaining Offered Rate Loan would be
                  less than $500,000);

                                       2

<PAGE>

                           (iv) elect to Continue, as of the last day of the
                  applicable Interest Period, any LIBOR Loan having an Interest
                  Period expiring on such day (or any part thereof in a minimum
                  amount of $1,000,000); and

                           (v) elect to Continue, as of the last day of the
                  applicable Interest Period, any Offered Rate Loan having an
                  Interest Period expiring on such day (or any part thereof in a
                  minimum amount of $500,000).

                  (b) The Company shall give written or telephonic notice to the
Bank not later than (i) 11:00 A.M. (Chicago time) at least three Business Days
in advance of the proposed date of such Conversion or Continuation, if the Loans
are to be Converted into or Continued as LIBOR Loans and (ii) not later than
11:00 A.M. (Chicago time) on the proposed date of such Conversion or
Continuation, if the Loans are to be Converted into Domestic Rate Loans or
Converted into or Continued as Offered Rate Loans, specifying:

                  (A)  the proposed date of such Conversion or Continuation;

                  (B) the aggregate principal amount of Loans to be Converted or
Continued;

                  (C) the Type of Loans resulting from the proposed Conversion
or Continuation; and

                  (D) in the case of Conversions into or Continuations of LIBOR
Loans or Offered Rate Loans, the duration of the requested Interest Period.

                  (c) If the Company fails to give timely notice pursuant to
CLAUSE (B) above of the continuation of a LIBOR Loan or an Offered Rate Loan or
the Bank declines to continue any Offered Rate Loan for a new Interest Period,
such LIBOR Loan or Offered Rate Loan shall automatically Convert to a Domestic
Rate Loan on the last day of the Interest Period therefor.

                  SECTION 1.5 WARRANTY. Each notice of borrowing,
Continuation and/or of Conversion pursuant to SECTION 1.3 or 1.4 shall
automatically constitute a warranty by the Company to the Bank to the effect
that on the date of such requested borrowing, Continuation or Conversion, as the
case may be, (a) the warranties of the Company contained in SECTION 8 of this
Agreement shall be true and correct as of such requested date as though made on
the date thereof and (b) no Event of Default or Unmatured Event of Default shall
have then occurred and be continuing or will result therefrom.

         SECTION 1.6 CONDITIONS. Notwithstanding any other provision of this 
Agreement, the Bank shall not be obligated to make any Loan or to Convert into 
or permit the Continuation at the end of the applicable Interest Period of any 
LIBOR Loan if an Event of Default or Unmatured Event of Default exists or 
would result therefrom.

                                       3

<PAGE>


         SECTION 2 NOTE EVIDENCEING LOANS. The Loans shall be evidenced by a
promissory note (the "Note") substantially in the form set forth in EXHIBIT
A, with appropriate insertions, dated the Effective Date (or such earlier
date as shall be satisfactory to the Bank), payable to the order of the
Bank in the principal amount of the Commitment (or, if less, in the
aggregate unpaid principal amount of the Loans). The Bank shall record in
its records, or at its option on the schedule attached to the Note, the
date and amount of each Loan, each repayment, Continuation or Conversion
thereof and, in the case of each LIBOR Loan and Offered Rate Loan, the
dates on which each Interest Period for such Loan shall begin and end. The
aggregate unpaid principal amount so recorded shall be rebuttable
presumptive evidence of the principal amount owing and unpaid on the Note.
The failure to so record any such amount or any error in so recording any
such amount shall not, however, limit or otherwise affect the obligations
of the Company hereunder or under the Note to repay the principal amount of
the Loans together with all interest accruing thereon.

         SECTION 3  INTEREST.

         . The Company promises to pay interest on the unpaid principal amount
of each Loan for the period commencing on the date of such Loan until such Loan
is paid in full, as follows:

                  (a)  at all times while such Loan is a Domestic Rate Loan, 
         at a rate per annum equal to the Domestic Rate from time to time 
         in effect;

                  (b) at all times while such Loan is a LIBOR Loan, at a rate

         Period for such Loan plus the applicable percentage set forth in
         SCHEDULE 3.1; and

                  (c) at all times while such Loan is an Offered Rate Loan, at a

Rate Loan shall be payable on the last day of each calendar quarter and at

of the first day of such Interest Period) and at maturity. After maturity,
accrued interest on all Loans shall be payable on demand.

         SECTION 3.3 COMPUTATION OF INTEREST. Interest shall be computed for 
the actual number of days elapsed on the basis of a year of 360 days. The

simultaneously with each change in the Domestic Rate.

         SECTION 4 FEES. The Company agrees to pay to the Bank a commitment 
fee, for the period from and including the Effective Date to the Termination
Date, in an amount equal to the commitment fee rate (determined as set
forth on SCHEDULE 3.1) per annum on the daily average of the amount by
which the amount of the Commitment exceeds the outstanding principal amount
of the Loans. Such commitment fee shall be payable in arrears on the last
day of each calendar quarter and on the Termination Date for any period
then ending for which such commitment fee shall not have been theretofore
paid. The commitment fee shall be computed for the actual number of days
elapsed on the basis of a year of 360 days.

         SECTION 5  REDUCTION OR TERMINATION OF THE COMMITMENT;
                            VOLUNTARY PREPAYMENTS.

may from time to time on at least three Business Days' prior written notice
received by the Bank permanently reduce the amount of the Commitment to an
amount not less than the aggregate unpaid principal amount of the Loans
then outstanding. Any such reduction shall be in an aggregate amount of at
least $25,000. The Company may at any time on like notice terminate the
Commitment upon payment in full of the Loans and all other obligations of
the Company hereunder.

         (b) During the period from July 30, 1998 to October 30, 1998, the
Commitment shall be reduced concurrently with the receipt by the Parent or any
Subsidiary of the Parent of any net cash proceeds from any long-term debt
financing; PROVIDED that the Commitment shall not be reduced to less than
$10,000,000 pursuant to this SECTION 5.1(B).

         (c) On October 30, 1998, the Commitment shall be reduced by an amount

         SECTION 5.2 PREPAYMENTS. (a) The Company shall have the privilege of 
prepaying without premium or penalty and in whole or in part (but if in

any time upon notice to the Bank prior to 11:00 a.m. (Chicago time) on the
date of prepayment.

         (b) The Company may prepay any LIBOR Loan or Offered Rate Loan without
premium or penalty in whole or in part (but if in part, then in an amount not
less than $1,000,000 in the case of LIBOR Loans and $500,000 in the case of
Offered Rate Loans), but only on the last day of the then applicable Interest
Period, upon notice to the Bank not later than 11:00 A.M. (Chicago time) three
Business Days prior to the date of such prepayment (which notice shall be
irrevocable once given and shall specify the principal amount to be repaid);
PROVIDED that the outstanding principal amount of any LIBOR Loan or Offered Rate
Loan prepaid in part shall not be less than $1,000,000 in the

                                       5

<PAGE>

case of LIBOR Loans and $500,000 in the case of Offered Rate Loans after 
giving effect to such prepayment. Any such prepayment shall be effected by
payment of the principal amount to be prepaid and accrued interest thereon to 
the end of the applicable Interest Period.

         (c) On each date on which the Commitment is reduced pursuant to SECTION
5.1(B) or (C), the Company shall make a prepayment of the Loans in the amount
(if any) by which the aggregate principal amount of the Loans exceeds the
Commitment as so reduced.


         SECTION 6  MAKING OF PAYMENTS; SETOFF.

         SECTION 6.1 MAKING OF PAYMENTS. All payments of principal, interest, 
fees and all other amounts payable hereunder shall be made to the Bank at
its principal office in Chicago, Illinois no later than 11:00 a.m. (Chicago
time) on the date any such payment is due and payable. All such payments
shall be made in lawful money of the United States of America, in
immediately available funds at the place of payment, without setoff or
counterclaim and without reduction for, and free from, any and all present
or future taxes, levies, imposts, duties, fees, charges, deductions,
withholdings, restrictions or conditions of any nature imposed by any
government or any political subdivision or taxing authority thereof (but
excluding any taxes imposed on or measured by the net income of the Bank).

         SECTION 6.2 APPLICATION OF CERTAIN PAYMENTS. Unless the Company 
otherwise directs, principal payments shall be first applied to the Domestic 
Rate Loans until payment in full thereof, then to Offered Rate Loans in the 
order in which their Interest Periods expire, with any balance applied to 
LIBOR Loans in the order in which their Interest Periods expire.

         SECTION 6.3 DUE DATE EXTENSION. If any payment hereunder falls due on 
a day which is not a Business Day, then such due date shall be extended to
the next following Business Day (unless, in the case of a LIBOR Loan or an
Offered Rate Loan, such immediately following Business Day is the first
Business Day of a calendar month, in which case such due date shall be the
immediately preceding Business Day) and, in the case of principal,
additional interest shall accrue and be payable for the period of such
extension.

         SECTION 6.4 SETOFF. The Company agrees that the Bank has all rights of
set-off and bankers' lien provided by applicable law, and in addition
thereto, the Company agrees that at any time (i) any payment or other
amount owing by the Company under this Agreement is then due to the Bank or
(ii) any Event of Default, or any event which might mature into an Event of
Default described in SECTION 11.1.4, exists, the Bank may apply to the
payment of such payment or other amount (or, in the case of CLAUSE (II)
above, any obligation of the Company hereunder, whether or not then due)
any and all balances, credits, deposits, accounts or moneys of the Company
then or thereafter with the Bank.

         SECTION 7 INCREASED COSTS; SPECIAL PROVISIONS FOR LIBOR LOANS


         SECTION 7.1 INCREASED COSTS. (a) If (i) Regulation D or (ii) 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
the Bank (or any lending office of the Bank) 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 the Bank (or any lending office of the Bank)
         to any tax, duty or other charge with respect to LIBOR Loans, the Note
         or its obligation to make LIBOR Loans, or shall change the basis of
         taxation of payments to the Bank of the principal of or interest on
         LIBOR Loans or any other amounts due under this Agreement in respect of
         LIBOR Loans or its obligation to make LIBOR Loans (except for changes
         in the rate of tax on the overall net income of the Bank or its lending
         office imposed by the jurisdiction in which the Bank's principal
         executive office or lending office is located); or

                  (B) shall impose, modify or deem applicable any reserve
         (including, without limitation, any reserve imposed by the FRB, but
         excluding any reserve included in the determination of interest rates
         pursuant to SECTION 3), special deposit or similar requirement against
         assets of, deposits with or for the account of, or credit extended by,
         the Bank (or any lending office of the Bank); or

                  (C)  shall impose on the Bank (or its lending office) any 
         other condition affecting LIBOR Loans, the Note or its obligation to 
         make LIBOR Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D, to impose a cost on) the Bank (or any lending office of
the Bank) of making or maintaining any LIBOR Loan, or to reduce the amount of
any sum received or receivable by the Bank (or its lending office) under this
Agreement or under the Note with respect thereto, then within 10 days after
demand by the Bank (which demand shall be accompanied by a statement setting
forth the basis of such demand), the Company shall pay directly to the Bank such
additional amount or amounts as will compensate the Bank for such increased cost
or such reduction.

         (b) If the Bank shall reasonably determine that the adoption or
phase-in of any applicable law, rule or regulation regarding capital adequacy,
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the Bank (or
its lending office) or any Person controlling the Bank with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on the Bank's or such controlling Person's
capital as a consequence of the Bank's obligations hereunder (including, 

                                       7

<PAGE>

without limitation, the Commitment) to a level below that which the Bank or such
controlling Person could have achieved but for such adoption, change or
compliance (taking into consideration the Bank's or such controlling Person's
policies with respect to capital adequacy) by an amount deemed by the Bank or
such controlling Person to be material, then from time to time, within 10 days
after demand by the Bank (which demand shall be accompanied by a statement
setting forth the basis of such demand), the Company shall pay to the Bank such
additional amount or amounts as will compensate the Bank or such controlling
Person for such reduction.

         SECTION 7.2 BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR. 
If with respect to any Interest Period deposits in Dollars (in the applicable 
amount) are not being offered to the Bank in the interbank eurodollar
market for such Interest Period, or the Bank otherwise determines (which
determination shall be binding and conclusive on the Company) that by reason of
circumstances affecting the interbank eurodollar market adequate and reasonable
means do not exist for ascertaining the applicable Adjusted LIBOR; THEN the Bank
shall promptly notify the Company thereof and, so long as such circumstances
shall continue, (i) the Bank shall be under no obligation to make, Continue or
Convert into LIBOR Loans and (ii) on the last day of the current Interest Period
for each LIBOR Loan, such Loan shall, unless then repaid in full, automatically
Convert to a Domestic Rate Loan.

         SECTION 7.3 CHANGES IN LAW RENDERING CERTAIN LOANS UNLAWFUL. In the 
event that any change in (including the adoption of any new) applicable laws 
or regulations, or any change in the interpretation of applicable laws or 
regulations by any governmental or other regulatory body charged with the
administration thereof, should make it (or in the good faith judgment of
the Bank raise a substantial question as to whether it is) unlawful for the
Bank to make, maintain or fund LIBOR Loans, then the Bank shall promptly
notify the Company and, so long as such circumstances shall continue, (a)
the Bank shall have no obligation to make, Continue or Convert into LIBOR
Loans and (b) on the last day of the current Interest Period for each LIBOR
Loan (or, in any event, if the Bank so requests, on such earlier date as
may be required by the relevant law, regulation or interpretation), such
LIBOR Loan shall, unless then repaid in full, automatically Convert to a
Domestic Rate Loan.

         SECTION 7.4 FUNDING LOSSES. The Company hereby agrees that upon 
demand by the Bank (which demand shall be accompanied by a statement
setting forth the basis for the calculations of the amount being claimed)
the Company will indemnify the Bank against any net loss or expense which
the Bank may sustain or incur (including, without limitation, any net loss
or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by the Bank to fund or maintain any LIBOR
Loan), as reasonably determined by the Bank, as a result of (a) any
payment, prepayment, Continuation or Conversion of any LIBOR Loan on a date
other than the last day of an Interest Period for such Loan (including,
without limitation, any Conversion pursuant to SECTION 7.3) or (b) any
failure of the Company to borrow, Continue or Convert any Loan on a date
specified therefor in a notice of borrowing, Continuation or Conversion
pursuant to this Agreement. For this purpose, all notices to the Bank
pursuant to this Agreement shall be deemed to be irrevocable.

                                       8

<PAGE>

         SECTION 7.5 RIGHT OF BANK TO FUND THROUGH OTHER OFFICES. The Bank may, 
if it so elects, fulfill its commitment as to any LIBOR Loan by causing a
foreign branch or affiliate of the Bank to make such Loan, PROVIDED that in
such event for the purposes of this Agreement such Loan shall be deemed to
have been made by the Bank and the obligation of the Company to repay such
Loan shall nevertheless be to the Bank and shall be deemed held by it, to
the extent of such Loan, for the account of such branch or affiliate.

         SECTION 7.6 DISCRETION OF BANK AS TO MANER OF FUNDING. Notwithstanding
any provision of this Agreement to the contrary, the
Bank 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 the
Bank had actually funded and maintained each LIBOR Loan during each Interest
Period for such Loan through the purchase of deposits having a maturity
corresponding to such Interest Period and bearing an interest rate equal to the
Adjusted LIBOR for such Interest Period.

         SECTION 7.7 CONCLUSIVENESS OF STATEMENTS: SURVIVAL OF PROVISIONS. 
Determinations and statements of the Bank pursuant to SECTION 7.1, 7.2, 
7.3 or 7.4 shall be conclusive absent demonstrable error. The Bank may use
reasonable averaging and attribution methods in determining compensation under
SECTIONS 7.1 and 7.4, and the provisions of such Sections shall survive
termination of this Agreement.

         SECTION 8  WARRANTIES.

         To induce the Bank to enter into this Agreement and to make Loans

determined, materially and adversely affect (i) the financial condition or
continued operations of the Company and its Subsidiaries or (ii) the ability of
the Company to perform its obligations hereunder or under the Note, EXCEPT as
set forth (including estimates of the dollar amounts involved) in a schedule
heretofore furnished by the Company to the Bank. Other than any liability
incident to such litigation or proceedings, neither the Company nor any
Subsidiary has any material contingent liabilities.

Company Act of 1935, as amended.

         SECTION 8.9 INFORMATION. All information heretofore or 
contemporaneously herewith furnished by the Company to the Bank for purposes of
or in connection with this Agreement and the transactions contemplated hereby
is, and all information hereafter furnished by or on behalf of the Company to

until all obligations of the Company hereunder and under the Note are paid in
full, the Company agrees that, unless at any time the Bank shall otherwise

Period. "LIBOR Index Rate" means, for any Interest Period, the rate per
