                                   ARTICLE II


                                   THE CREDIT


     2.1   Commitment.  From and including the date of this Agreement and prior
to the Facility Termination Date, each Lender severally agrees, on the terms and
conditions set forth in this Agreement, to make Loans to Borrowers from time to
time in amounts not to exceed in the aggregate at any one time outstanding the
amount of its Commitment, and on the Closing Date, the Agent agrees to issue the
Interim Letter of Credit; provided, however, that in no event shall the
Aggregate Commitment hereunder exceed $200,000,000; and in no event shall Loans
made to or for the benefit of Maryland and Technologies, together, or
individually, exceed $75,000,000.  Subject to the terms of this Agreement,
Borrowers may borrow, repay and reborrow at any time prior to the Facility
Termination Date. The Commitments to lend hereunder shall expire on the Facility
Termination Date.

     2.2   Final Principal Payment. Any outstanding Loans and all other unpaid
Obligations shall be paid in full by Borrowers on the Facility Termination Date.

     2.3   Ratable Loans. Each Advance hereunder shall consist of Loans made
from the several Lenders ratably in accordance with their Pro Rata Share of the
Aggregate Commitment.

     2.4   Applicable Margins.  The CD Applicable Margin, Base Rate Applicable
Margin and LIBOR Applicable Margin shall be calculated based on the following
performance grid (pricing is based on the higher of the rates resulting from
independent application of the first two columns and is adjusted on the day
following the last day of the Initial Interest Period, and

                                      -17-

   23
thereafter on the first day of each calendar quarter, based on annualized
results (i.e., the ratio of (a) the product of (i) the sum of Consolidated Net
Income plus Consolidated Interest Expense for such quarter multiplied by four
(4) divided by (b) the sum of (i) the product of Consolidated Interest Expense
multiplied by four plus (ii) the Current Portion of Long Term Debt) for the
immediately preceding quarter; provided, however, that in the case of the
adjustment following the Initial Interest Period, the Applicable Margin shall be
determined using annualized results for the quarter ending March 31, 1996. If
upon the expiration of the Initial Interest Period financial statements are not
yet available for the quarter ending March 31, 1996, Borrowers shall continue to
pay interest at the interest rate in effect at the expiration of the Initial
Interest Period and, upon delivery of such statements, an amount equal to
Deferred Interest, if any, shall be immediately due and payable).  To the extent
that, as of an adjustment date, Borrowers have not provided to Agent information
necessary to apply the performance grid, interest shall be payable retroactively
upon receipt of such information and calculation by Agent.  In such event,
Borrowers shall continue to pay interest at the interest rate and on the Payment
Dates in effect for the preceding quarter and the parties shall adjust for the
difference between interest payable and interest actually paid, when information
to apply the performance grid is available.

        2.5 Commitment Fee; Closing Fee; Interim Letter of Credit Fee. (a)
Borrowers agree to pay to Agent for the account of

                                      -18-

   24
each Lender a commitment fee (the "Commitment Fee") calculated at the rate of
0.25% per annum on the daily unborrowed portion of such Lender's Commitment from
the Closing Date to and including the Facility Termination Date, payable
quarterly in arrears on the first day of each calendar quarter hereafter
beginning January 2, 1996, and on the Facility Termination Date.


     (b)   Borrowers further agree to pay to Agent for the account of each
Lender a closing fee (the "Closing Fee") in the aggregate amount of $125,000.
Borrowers have heretofore paid to Agent for the account of each Lender one-half
of the Closing Fee ($62,500), and Borrowers shall pay the remaining one-half of
the Closing Fee ($62,500), to Agent for the account of each Lender on the
Closing Date.

     (c)   Borrowers further agree to pay to Agent for the account of each
Lender a letter of credit fee (the "Letter of Credit Fee") in the aggregate
amount of $44,792.00, payable on the Closing Date.

     2.6   Other Fees. Borrowers agree to pay all fees payable to Agent pursuant
to the Interim Letter of Credit or a separate letter agreement.

     2.7   Minimum Amount of Loans.  Base Rate Loans and CD Rate Loans shall be
in the minimum amount of $5,000,000, and in multiples of $1,000,000 if in excess
thereof.  LIBOR Rate Loans shall be in the minimum amount of $10,000,000, and in
multiples of $1,000,000 if in excess thereof.

     2.8   Interest Payable on the Loans.

     (a)   Initial  Interest.    Notwithstanding  any  other provision hereof,
all Advances hereunder made pursuant to a Borrowing Notice delivered by
Borrowers on or before May 29, 1996, and all Advances made pursuant to a draw on
the Interim Letter of Credit shall consist of Loans bearing interest until and
including the last day of the Initial Interest Period, at a deemed Applicable
Margin as follows, as selected by Borrowers:.

     (i)   For LIBOR Rate Loans:  .625%; or

     (ii)  For CD Rate Loans:  .75%; or

     (iii) For Base Rate Loans:  0%.

     As of the day following the last day of the Initial Interest Period, and
notwithstanding any Interest Period then in effect, Applicable Margins shall be
determined by reference to the table in Section 2.4 hereof.

          (b) Method of Selecting Rate Options and Interest Periods.
(i) Borrowers shall select the Rate Option for each

                                      -19-

   25
Advance and shall select the Interest Period applicable to each CD Rate Loan and
LIBOR Rate Loan from time to time, by delivery to Agent of an irrevocable notice
in the form of Exhibit C hereto (a "Borrowing Notice"), or by telephonic notice
to Agent ("Telephonic Notice"), followed by a same day (which shall mean prior
to 5:00 p.m. Cleveland, Ohio, time) written Borrowing Notice delivered to Agent
via facsimile.  Such Borrowing Notice shall indicate the name of the particular
Borrower to or for the benefit of which such Advance shall be made.

     (ii)  Each CD Rate Loan and LIBOR Rate Loan shall bear interest from and
including the first day of the Interest Period applicable thereto until (but not
including) the last day of such Interest Period at the interest rate determined
as applicable to such Loan. Borrowers shall select Interest Periods with respect
to CD Rate Loans and LIBOR Rate Loans so that it is not necessary to pay such
Loan prior to the last day of the applicable Interest Period in order to repay
the Loans on the Facility Termination Date.  Provided that no Default shall have
occurred and be continuing, Borrowers may elect to continue a Loan as a CD Rate
Loan or LIBOR Rate Loan, as the case may be, by giving irrevocable written,
telephonic or telegraphic notice thereof to Agent not more than ten (10) nor
less than three (3) Business Days prior to the last day of the then-current
Interest Period for such Loan, specifying the duration of the succeeding
Interest Period therefor. If Agent does not receive timely notice of such
election, Borrowers shall be deemed to have elected to convert such Loan to a
Base Rate Loan at the end of the then-current Interest Period.  Provided that no
Default shall have occurred and be continuing, Borrowers may, on any Business
Day, convert any outstanding Base Rate Loan, or portion thereof, into a CD Rate
Loan or a LIBOR Rate Loan in the same aggregate principal amount.  If Borrowers
desire to convert a Base Rate Loan, it shall give Agent prior written or
telephonic notice not more than ten (10) nor less than three (3) Business Days
prior to the requested conversion date, which notice shall specify the duration
of the Interest Period applicable thereto.

     (c)   Determination of Adjusted Base Rate.  Agent shall determine the
Base Rate in effect from time to time. Any change in the Base Rate shall, for
all purposes of this Agreement and the other Loan Documents, become effective on
the effective date of such change in the Base Rate as announced by Agent in
accordance with Agent's customary practices.

     (d)   Monthly Installments.


           (i)   Borrowers shall pay to Agent, for the account of Lenders in
                 accordance with their respective Pro Rata Share, monthly in
                 arrears on the last Business Day of each month beginning with
                 the month following the month in which the Closing Date occurs,
                 interest on the outstanding principal amount of the Base Rate
                 Loans at the

                                      -20-

   26
                 annual rate equal to the Base Rate plus the Base Rate
                 Applicable Margin; provided, however, that if Borrowers elect,
                 pursuant to the final paragraph of Section 2.4(a), to convert a
                 Base Rate Loan, or any portion thereof, to a CD Rate Loan or a
                 LIBOR Rate Loan, Borrowers shall pay to Agent, for the account
                 of Lenders in proportion to their respective Commitments, all
                 accrued but unpaid interest on such Base Rate Loan, or that
                 portion thereof which is being so converted, for the period
                 commencing on the date of the last payment date under this
                 paragraph 2.8(d)(i) and concluding on the day immediately
                 preceding the first day of the Interest Period for the CD Rate
                 Loan or the LIBOR Rate Loan into which such Base Rate Loan is
                 converted.


           (ii)  Borrowers shall pay to Agent, for the account of Lenders in
                 accordance with their Pro Rata Share, in arrears, interest on
                 the outstanding principal amount of the CD Rate Loans and the
                 LIBOR Rate Loans at the annual rate equal to the CD Rate or the
                 LIBOR Rate, as applicable. Such interest shall be due and
                 payable on the last Business Day of the applicable Interest
                 Period of ninety (90) days or less, for all other CD Rate Loans
                 and LIBOR Rate Loans, interest shall be payable, in arrears as
                 aforesaid, on (x) that Business Day which is ninety (90) days
                 after the beginning of the Interest Period for such Loans; and
                 (y) on the final day of the Interest Period therefor.


     (e) Interest on Overdue Payments; Default Interest Rate.  If any payment of
principal or interest is not paid when due, or prior to the expiration of the
applicable period of grace (if any) therefor, Agent may charge and collect from
Borrowers, or may add to the unpaid balance of the Notes, a Late Charge. Any
Late Charge charged and collected by the agent shall be distributed to Lenders
in proportion to their respective Commitments.  No failure by Agent to charge or
collect any Late Charge in respect of any delinquent payment shall be considered
to be a waiver by Agent or Lenders of any rights they may have hereunder,
including without limitation the right subsequently to impose a Late Charge for
such delinquent payment or to take such other actions as may then be available
to them hereunder or at law or in equity, including but not limited to the right
to terminate the Commitments and/or to accelerate the Obligations pursuant to
the terms hereof.  If the Notes have been accelerated pursuant to this Agreement
or if a Default hereunder or under any other Loan Document shall have occurred
and be continuing, the outstanding principal balance of the Indebtedness

                             -21-

   27
advanced under this Agreement, together with all accrued interest thereon and
any and all other Obligations, shall bear interest from the date on which such
amount shall have first become due and payable to the date on which such amount
shall be paid (whether before or after judgment) at the Default Interest Rate.
Interest at the Default Interest Rate will continue to accrue and will (to the
extent permitted by applicable law) be compounded daily until the Obligations in
respect of such payment are discharged (whether before or after judgment).

     2.9   Repayments and Prepayments of Principal.

     (a)   Optional Prepayments.  Without derogating from the mandatory
prepayment requirements contained in Section 2.9(b) hereof, Borrowers may prepay
the principal of the Loans in full or in part at any time and from time to time
upon payment to Agent of all accrued interest to the date of payment; provided,
however, that (i) all partial payments of principal shall be in an amount equal
to or greater than One Hundred Thousand Dollars ($100,000.00); and (ii) all
Loans may be prepaid without penalty or premium. If Borrowers shall prepay any
Loan which is a LIBOR Rate Loan or a CD Rate Loan on a day other than the final
day of the applicable Interest Period therefor, such prepayment must include an
amount equal to all of Lenders' aggregate LIBOR Break Funding Costs or CD Break
Funding Costs, respectively, applicable to or resulting from such prepayment in
accordance with Section 2.9, below.

     (b)   Mandatory Prepayments.  If at any time the aggregate principal 
balance of all Loans made hereunder exceeds the aggregate amount of the 
Commitments Borrowers shall immediately prepay an amount equal to such excess.

     (c)   Application of Prepayments.  Any prepayment of the Obligations shall
be applied by Agent as set forth in Section 2.10 hereof.  To the extent that
such payment, repayment or prepayment shall be applied to a CD Rate Loan or a
LIBOR Rate Loan, Agent shall retain such amount until the expiration of the
Interest Period applicable to such Loan, and, shall apply such payment at such
time so as to minimize the LIBOR Break Funding Costs or CD Break Funding Costs
applicable to such payment, repayment or prepayment, unless otherwise instructed
by Borrowers to pay, repay or prepay such Loan and nonetheless incur the
applicable LIBOR Break Funding Cost or CD Break Funding Cost.

          (d) Maturity.  Subject to the terms and conditions of
this Agreement, Borrowers will be entitled to reborrow all or any
part of the principal of the Notes repaid or prepaid prior to the
termination of the Commitments.  The Commitments shall terminate,
and all of the Indebtedness evidenced by each Note shall, if not
sooner paid, be in any event absolutely and unconditionally due and
payable in full by Borrowers, on the Facility Termination Date.

                                      -22-

   28
     (e)   Notice of Prepayments of Principal.  Borrowers will provide Agent
at least (1) one Business Day's advance, written notice of their intention to
make any voluntary prepayment of principal.  Such notice shall be irrevocable
and shall specify the date of prepayment and the aggregate amount to be paid.

     (f)   Reduction in Commitment.  Provided there is not then any Default or
Unmatured Default hereunder or any other Loan Document, Borrowers may, upon and
subject to the terms and conditions set forth in this Section 2.9(f), elect
permanently to reduce the Aggregate Commitment by providing Agent and each
Lender with not less than thirty (30) days' prior written notice of its election
to do so.  Such notice shall specify the date on which such reduction is
intended to become effective and the amount to which Borrowers would propose to
reduce the Aggregate Commitment. Provided that Borrowers shall, on or prior to
the effective date for such reduction specified in such notice, have made such
payments or prepayments as may be necessary to cause the outstanding balance of
all Loans to Borrowers to be reduced to an amount equal to or less than the
amount of the Aggregate Commitment (giving effect to the proposed reduction
thereof contemplated in Borrowers' notice), the Aggregate Commitment shall, on
the date specified in Borrowers' notice, be reduced to the amount stipulated in
Borrowers' notice.  In the event that Borrowers shall elect to reduce the
Aggregate Commitment as aforesaid, each Lender's commitment shall be reduced,
pro rata, to reflect any such reduction in the Aggregate Commitment, and the
amount of the Commitment Fee payable during the fiscal quarter in which such
reduction shall become effective shall be calculated so as to give effect to
such reduction, as of the effective date thereof, on a per diem basis.  Each
reduction in the amount of the Aggregate Commitment effected pursuant to this
Section 2.9(f) shall be in a multiple of Five Million Dollars ($5,000,000), and
the minimum reduction shall be Twenty-Five Million Dollars ($25,000,000).  Each
reduction in the amount of the Aggregate Commitment shall be permanent.
Borrowers may exercise their right permanently to reduce the amount of the
Aggregate Commitment not more frequently than twice during any six-month period.
Borrowers shall pay all reasonable costs and expenses of Agent (including,
without limitation, reasonable attorney's fees) incurred in connection with the
exercise of Borrowers' rights under this Section 2.9(f).

     2.10   Payments and Computations.

     (a)   Time and Place of Payments. Each payment to be made by Borrowers
under this Agreement or any other Loan Documents shall be made directly to Agent
at its Head Office, not later than 12:00 noon Cleveland time, on the due date of
each such payment, in immediately available and freely transferrable funds.  Any
payment received after such time will be deemed to have been received on the
next Business Day.  Agent will, on the same Business Day that it receives (or is
deemed to receive, as aforesaid) each such payment, cause to be distributed to
each Lender, in immediately

                                      -23-

   29
available and freely transferrable funds, such Lender's Pro Rata Share of each
such payment received by Agent.

     (b)   Application of Funds.  Notwithstanding anything herein to the 
contrary, the funds received by Agent with respect to the Obligations shall be 
applied as follows:

     (i)   No Default.  Provided that the Notes have not been accelerated
           pursuant to Section 7.1, below, and provided further that no Default
           or Unmatured Default hereunder or under any Loan Document shall have
           occurred and be continuing at the time that Agent receives such
           funds, in the following manner: (a) first, to the payment of all
           fees, charges, and other sums (other than principal and interest)
           then due and payable to Agent or Lenders under the Notes, this
           Agreement or the other Loan Documents (including, without limitation,
           any LIBOR Break Funding Costs or CD Break Funding Costs which may
           then be payable); (b) second, to the payment of all accrued but
           unpaid interest at the time of such payment in accordance with each
           Lender's Pro Rata Share; and (c) third, to the payment of principal
           of the Notes in accordance with Lender's Pro Rata Shares.

     (ii)  Default.    If  the  Notes  have been accelerated pursuant to Section
           7.1, or if a Default hereunder shall have occurred and be continuing
           hereunder or under the Notes or any of the other Loan Documents at
           the time Agent receives such funds, in the following manner:  (a)
           first to the payment or reimbursement of Lenders and Agent for all
           costs, expenses, disbursements and losses which shall have been
           incurred or sustained by Lenders or Agent in or incidental to the
           collection of the Obligations owed by Borrowers hereunder or the
           exercise, protection, or enforcement by Lenders or Agent of all or
           any of the rights, remedies, powers and privileges of Lenders and
           Agent under this Agreement, the Notes, or any of the other Loan
           Documents and in and towards the provision of adequate indemnity to
           Agent and any of Lenders against all taxes or Liens which by law
           shall or may have priority over the rights of Agent or Lenders in and
           to such funds; and (b) second to the payment of all of the
           Obligations in accordance with Section 2.10(b)(i) above.

     (c)   Payments on Business Days.  If any sum would (but for the provisions
of this Section 2.10(c)) become due and payable on any day which is not a
Business Day, then such sum shall become due and payable on the next succeeding
Business Day, and interest

                                      -24-

   30
payable on such sum shall continue to accrue and shall be adjusted by Agent
accordingly.

     (d)   Computation of Interest.    All computations of interest payable
under this Agreement, the Notes, or any of the other Loan Documents shall be
computed by Agent on the basis of the actual principal amount outstanding on
each day during the payment period, and shall be calculated with reference to
the actual number of days elapsed during such period on the basis of a year
consisting of three hundred and sixty (360) days.  The daily interest charge
shall be one three-hundred-sixtieth (1/360th) of the annual interest amount.
Each determination of any interest rate by Agent shall be conclusive and binding
on Borrowers in the absence of manifest error.  Absent manifest error, a
certificate or statement signed by an authorized officer of the Agent shall be
conclusive evidence of the amount of the Obligations due and unpaid as of the
date of such certificate or statement.

     2.11  Payments to be Free of Deductions.  Each payment to be made by
Borrowers under this Agreement, any Note, or any of the other Loan Documents
shall be made in accordance with Section 2.10 hereof, without set-off, deduction
or counterclaim whatsoever, and free and clear of taxes, levies, imposts,
duties, charges, fees, deduction, withholdings, compulsory loans, restrictions
or conditions of any nature now or hereafter imposed or levied by any
governmental or taxing authority, unless Borrowers are compelled by law to make
any such deduction or withholding.  In the event that any such obligation to
deduct or withhold is imposed upon Borrowers with respect to any such payment:
(a) Borrowers shall be permitted to make the deduction or withholding required
by law in respect of the said payment, and (b) there shall become and be
absolutely due and payable by Borrowers to Agent or such Lender on the date on
which the said payment shall be due and payable, and Borrowers hereby promise to
pay to Agent or such Lender on such date, such additional amount as shall be
necessary to enable Agent or such Lender to receive the same net amount which
Agent or such Lender would have received on such due date had no such obligation
been imposed by law. Notwithstanding any provision of this Section 2.11 to the
contrary, the foregoing provisions of this Section 2.11 shall not apply in the
case of any deductions or withholding made (y) in respect of taxes charged upon
or by reference to the overall net income, profits or gains of Agent or any
Lender, or (z) failure by a Lender to comply with Section 2.21.

          2.12 Use of Proceeds.  Borrowers represent, warrant and covenant to
Agent and to each Lender that all proceeds of the Advances shall be used by
Borrowers only for the following purposes:  (i) the Technologies Acquisition,
(ii) refinancing existing Indebtedness for Borrowed Money, (iii) Working Capital
needs, and (iv) Acquisitions, to the extent expressly permitted under this
Agreement and (v) except as expressly limited in this Agreement, general
corporate purposes.

                                      -25-

   31
     2.13  LIBOR Break Funding Cost; CD Break Funding Cost.  Borrowers shall pay
to Agent, for the ratable benefit of each Lender, the LIBOR Break Funding Costs
or CD Break Funding Costs that Agent determines are attributable to:

     (a)   any payment (including, without limitation, any payment resulting
from the acceleration of the Loans pursuant to this Agreement or any Loan
Document), repayment, mandatory or optional prepayment, or conversion of a LIBOR
Rate Loan or CD Rate Loan for any reason on a date other than the last day of
the Interest Period for such LIBOR Rate Loan or CD Rate Loan; or

     (b)   any failure by Borrowers for any reason to borrow a LIBOR Rate Loan
or CD Rate Loan on the date for such borrowing specified in the relevant notice
of borrowing or Borrowing Notice given pursuant to this Agreement.

     2.14  Additional Costs.

     (a)   Notwithstanding any conflicting provisions of this Agreement to the
contrary, if any applicable law, rule or regulation not in effect as of the date
hereof shall (i) subject Agent or any Lender to any tax, levy, impost, duty,
charge, fee, deduction or withholding of any nature with respect to any Loan,
this Agreement, any Note, or any of the other Loan Documents or the payment by
Borrowers of any amounts payable to Agent or any Lender hereunder or thereunder
(other than taxes charged upon or by reference to the overall net income,
profits or gains of Agent or any Lender or taxes charged with respect to any
Lender's failure to comply with Section 2.21 hereof); or (ii) materially change,
in the reasonable opinion of the party so affected, the basis of taxation (other
than changes in tax rates applicable to taxes charged upon or by reference to
the overall net income, profits or gains of Agent or any Lender or taxes charged
with respect to any Lender's failure to comply with Section 2.21 hereof) of
payments to Agent or any Lender of the principal of or the interest on any Note
or any other amounts payable to Agent or any Lender under this Agreement, or any
of the other Loan Documents; or (iii) impose or increase or render applicable
any special or supplementary special deposit or reserve or similar requirements
(whether or not having the force of law) against assets held by, or deposits in
or for the account of, or any eligible liabilities of, or loans by any office or
branch of, Agent or any Lender; or (iv) impose on Agent or any Lender any other
condition or requirement with respect to this Agreement, any Note, or any of the
other Loan Documents, and if the result of any of the foregoing is (A) to
increase the cost to Agent or any Lender of making, funding or maintaining all
or any part of the principal of the Loans, or (B) to reduce the amount of
principal, interest or any other sum payable by Borrowers to Agent or any Lender
under this Agreement, any Note, or any of the other Loan Documents, or (C) to
require Agent or any Lender to make any payment or to forego any interest or
other sum payable by Borrowers to Agent or any Lender under this Agreement, any
Note, or any of the other Loan

                                      -26-

   32
Documents, the amount of which payment or foregone interest or other sum is
measured by or calculated by reference to the gross amount of any sum receivable
or deemed received by Agent or any Lender from Borrowers under this Agreement,
any Note, or any of the other Loans Documents, then, and in each such case,
Borrowers will pay to Agent for Agent or the account of a Lender, as the case
may be, within sixty (60) days of written notice by Agent or such Lender, such
additional amounts as will (in the reasonable opinion of Agent or such Lender,
as the case may be) be sufficient to compensate Agent or such Lender for such
sum.

     (b)   If any present or future applicable law, rule or regulation shall
make it unlawful for any Borrowers to perform any one or more of its agreements
or Obligations under this Agreement, any Note, or any of the other Loan
Documents, then the obligations of Lenders under their respective Commitment
shall terminate immediately.   If any present or future applicable law, rule or
regulation shall make it unlawful for any Borrowers to perform any one or more
of its agreements or obligations under this Agreement, any Note, or any of the
other Loan Documents, and Agent, or any Lender shall at any time determine
(which reasonable determination shall be conclusive and binding on Borrowers)
(i) that, as a consequence of the effect or operation (whether direct or
indirect) of any such applicable law, rule or regulation, any one or more of the
rights, remedies, powers or privileges of Agent or any Lender under or in
respect of this Agreement, any Note, or any of the other Loan Documents shall be
or become invalid, unenforceable, or materially restricted; and (ii) that all or
any one or more of the rights, remedies, powers and privileges so affected are
of material importance to Agent or any Lender (as determined by the party so
affected), then Agent shall, at the direction of the Required Banks, by giving
notice to Borrowers, declare all of the Obligations, including, without
limitation, the entire unpaid principal of the Notes, all of the unpaid interest
accrued thereon and any and all other sums due and payable by Borrowers to Agent
or Lenders under this Agreement, any Note, and any of the other Loan Documents,
to be immediately due and payable, and, thereupon, such Obligations shall (if
not already due and payable) forthwith become and be due and payable without
further notice or other formalities of any kind, all of which are hereby
expressly waived.

     (c)   If Agent or any Lender shall reasonably determine that any law, rule
or regulation not in effect as of the date hereof regarding capital adequacy, or
in the event of any change in any existing such law, rule or regulation or 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 any Lender with any request or directive
regarding capital adequacy (whether or not having the force of law) from any
such authority, central bank or comparable agency, has or would have the effect
of reducing the rate of return on such Lender's capital, as a consequence of its
obligations hereunder, to a level below that which such Lender could have

                                      -27-

   33
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies with respect to capital adequacy) by any amount deemed by
such Lender to be material, then Borrowers shall pay to such Lender within sixty
(60) days of written notice by such Lender such amount or amounts, in addition
to the amounts payable under the provisions of this Agreement or any other Loan
Document, as will compensate such Lender for such reduction.  Determinations by
any Lender of the additional amount or amounts required to compensate such
Lender in respect of the foregoing shall be presumptively correct absent
manifest error.  In determining such amount or amounts, each Lender may use in
good faith any reasonable averaging and attribution methods of general
application.


     (d)   Each Lender agrees, that upon the occurrence of any event giving rise
to the operation of Section 2.11, or (a)-(c) of this Section 2.14 with respect
to such Lender, it will, to the extent permitted by Applicable Law or by the
relevant governmental authority, in consultation with the Agent, for a period of
thirty (30) days endeavor in good faith to avoid or minimize the increase in
costs or reduction in payments resulting from such event (including, but not
limited to, endeavoring to change its Lending Installation); providing, however,
that such avoidance or minimization can be made in such a manner that such
Lender, in its sole determination, suffers no economic, legal or regulatory
disadvantage. If any Lender (an "Affected Lender") shall make a demand for
payment under any of such Sections, and Borrowers shall find a Lender or an
assignee which offers in writing to purchase the Commitments and Advances of
such Affected Lender without recourse at par on a specified date, together with
accrued and unpaid interest and commitment fees thereon to the date of purchase,
and tenders the purchase price of such Commitments and Advances on such
specified date, and if, in the reasonable opinion of such Affected Lender, its
acceptance of such offer would be permitted under Applicable Law and all
relevant governmental authorities and would not result in its suffering any
economic, legal, or other regulatory disadvantage, then Borrowers shall be
excused from the payment of the increased costs claimed by such Affected Lender
under any of such Sections accruing after the first interest payment date
pursuant to Section 2.18 for each Advance of such Affected Lender following such
specified date, if the Affected Lender demanding payment under either such
Section declines such purchase offer.  If such Affected Lender accepts such
purchase offer, upon consummation of such purchase offer such Affected Lender
shall cease to be a party hereto.  Except as provided in the immediately
preceding sentence, nothing in this Section 2.14(d) shall affect or postpone the
obligations of Borrowers to make payments as provided hereunder.  Any reasonable
expenses incurred by such Affected Lender under this Section 2.14(d) shall be
paid by the Borrowers upon delivery by such Affected Lender to Borrowers of a
certificate as to the amount of such expenses, which certificate shall be
conclusive and binding, in absence of manifest error.

                                      -28-

   34
     (e)  For purposes of this Section 2.14, "laws, rules and regulations not in
effect on the date hereof" or similar words shall be deemed to include future
interpretations of existing laws, rules and regulations.


     2.15 Indemnification of Losses.  Without derogating from any of the other
provisions of this Agreement or any of the other Loan Documents Borrowers hereby
absolutely and unconditionally agree to indemnify Agent and each Lender, upon
demand at any time and as often as the occasion therefor may require, against
any and all claim, demands, suits, actions, damages, losses, costs, expenses and
all other liabilities whatsoever which Agent or any Lender or any of their
respective directors or officers may sustain or incur as a consequence of, on
account of, in relation to or in any way in connection with (a) any failure by
Borrowers to pay, punctually on the due date thereof, any amount payable under
this agreement, any Note, or any of the other Loan Documents beyond the
expiration of the period of grace (if any) applicable thereto, or (b) the
acceleration of the maturity of any of the Obligations, or (c) any failure by
any Borrower to perform or comply with any of the terms and provisions of this
Agreement, any Note or any of the other Loan Documents.  Such claims, demands,
suits, actions, damages, losses, costs, expenses shall include, without
limitation (i) any costs incurred by Agent or any lender in carrying funds to
cover any overdue principal, overdue interest or any other overdue sums payable
by Borrowers under this Agreement, any Note or any of the other Loan Documents;
(ii) any interest payable by Agent or any Lender in order to carry the fund
referred to in clause (i) of this Section 2.15; and (iii) any losses (but
excluding losses of anticipated profit) incurred or sustained by Agent or any
Lender in liquidating or re-employing funds acquired from third parties to make,
fund or maintain all or any part of the Loans.


     2.16 Statements by Agent or any Lender.  A certified statement signed by an
officer of Agent or any Lender setting forth any additional amount required to
be paid by Borrowers to Agent or such Lender (together with supporting
documentation setting forth in reasonable detail an explanation of the basis for
requesting payment of such amount), respectively, under Section 2.14 and 2.15
hereof shall be submitted by Agent or such Lender to Borrowers in connection
with each demand made at any time by Agent (with copies thereof delivered to
each other Lender) or such Lender under either of such Sections. A claim by
Agent or any Lender for all or any part of any additional amounts required to be
paid by Borrowers under Section 2.14 and 2.15 hereof may be made before or after
any payment to which such claim relates. Each such statement shall, in the
absence of manifest error, constitute presumptive evidence of the additional
amount required to be paid to Agent or such Lender.


     2.17 Borrowing Notices; Telephonic Notices.  (a) All requests for draws,
advances, or disbursements of Loan proceeds shall be made by and on behalf of
Borrowers in writing on a Borrowing Notice, or by Telephonic Notice. All
Telephonic Notices,



                                      -29-
   35
must be followed by same day (which shall mean prior to 5:00 p.m., Cleveland,
Ohio, time) written Borrowing Notice delivered to Agent via facsimile. Borrowing
Notices may be transmitted to Agent at its Head Office via fax or telecopy,
provided that Borrowers immediately notify Agent by telephone of such
transmission.  Each Borrowing Notice for Base Rate Loans shall be transmitted to
and received by Agent, or each Telephonic Notice shall be received by telephone
by Agent, not later than 12:00 p.m. Cleveland, Ohio, time not more than ten (10)
Business Days nor less than one (1) Business Day before the Borrowing Date of
each Base Rate Loan and not more than ten (10) Business Days nor less than three
(3) Business Days before the Borrowing Date for each CD Rate Loan or LIBOR Rate
Loan. All Borrowing Notices shall be accompanied by such documents, reports and
other materials as may be reasonably necessary to enable Agent (and each Lender)
to confirm that the conditions precedent to the disbursement of such requested
Loan have been satisfied.


     (b)  Agent shall notify Lenders promptly by telephone of its receipt of
Borrower's Borrowing Notice, but in no event shall Agent notify Lenders later
than 5:00 p.m. Cleveland time, on the day on which Agent actually receives the
applicable Borrowing Notice.  In addition, Agent shall provide each Lender with
a copy of each such Borrowing Notice, together with all accompanying materials,
promptly upon Agent's receipt thereof, and shall in addition provide each Lender
with a statement showing Agent's calculation of its respective Pro Rata Share of
the Advance so requested.  Each Lender will, upon receiving notice from Agent of
Borrower's Borrowing Notice, become and be obligated to place at the disposal of
Agent, not later than 10:00 a.m., Cleveland time, on the Borrowing Date set
forth on such Borrowing Notice, an aggregate amount in dollars equal to such
Lender's Pro Rata Share multiplied by the amount of the Advance requested.  The
payment by each Lender of such aggregate amount shall be made to Agent at
Agent's Head Office in immediately available and freely transferrable funds.


     (c)  Agent shall disburse the proceeds of each Loan to Borrowers, in
immediately available funds not later than noon, Cleveland time, on the
Borrowing Date described therefor, provided that: (x) Borrowers shall have
provided Agent with a Borrowing Notice for such Advance as and when provided
above; (y) all of the conditions precedent applicable to such Advance shall be
satisfied as at the Closing Date or such later Borrowing Date as may be
applicable to such Loan; and (z) each Lender shall fund the amount equal to its
Loan as provided in Section 2.17(b), above.


     2.18 Notes; Telephonic Notices.  Each Lender is hereby authorized to record
the principal amount of each of its Loans and each repayment on the schedule
attached to its Note, provided, however, that the failure to so record shall not
affect Borrowers' obligations under such Note.  Borrowers hereby authorize
Lenders and Agent to extend, convert or continue Loans, effect selections



                                      -30-
   36
of Types of Advances and to transfer funds based on telephonic notices made by
any person or persons Agent or any Lender in good faith believes to be acting on
behalf of Borrowers.  Borrowers agree to deliver promptly to Agent a written
confirmation, if such confirmation is requested by Agent or any Lender, of each
telephonic notice signed by an Authorized Officer.  If the written confirmation
differs in any material respect from the action taken by Agent and Lenders, the
records of Agent and Lenders shall govern absent manifest error.


     2.19 Lending Installations.  Each Lender may book its Loans at any Lending
Installation selected by such Lender and may change its Lending Installation
from time to time.  All terms of this Agreement shall apply to any such Lending
Installation and the Notes shall be deemed held by each Lender for the benefit
of such Lending Installation.  Each Lender may, by written or telex notice to
Agent and Borrowers, designate a Lending Installation through which Loans will
be made by it and for whose account Loan payments are to be made.


     2.20 Non-Receipt of Funds by Agent. Unless Borrowers or a Lender, as the
case may be, notifies Agent prior to the date on which it is scheduled to make
payment to Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii)
in the case of Borrowers, a payment of principal, interest or fees to Agent for
the account of Lenders, that it does not intend to make such payment, Agent may
assume that such payment has been made.  Agent may, but shall not be obligated
to, make the amount of such payment available to the intended recipient in
reliance upon such assumption.  If such Lender or Borrowers, as the case may be,
has not in fact made such payment to Agent, the recipient of such payment shall,
on demand by Agent, repay to Agent the amount so made available together with
interest thereon in respect of each day during the period commencing on the date
such amount was so made available by Agent until the date Agent recovers such
amount at a rate per annum equal to (i) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day or (ii) in the case of payment by
Borrowers, the interest rate applicable to the relevant Loan.


     2.21 Withholding Tax Exemption.  At least five Business Days prior to the
first date on which interest or fees are payable hereunder for the account of
any Lender, each Lender that is not incorporated under the laws of the United
States of America, or a state thereof, agrees that it will deliver to each
Borrower and Agent two duly completed copies of United States Internal Revenue
Service Form 1001 or 4224, certifying in either case that such Lender is
entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes.  Each Lender
which so delivers a Form 1001 or 4224 further undertakes to deliver to each
Borrower and Agent two additional copies of such form (or a successor form) on
or before the date that such form expires (currently, three successive



                                      -31-
   37
calendar years for Form 1001 and one calendar year for Form 4224) or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent forms so delivered by it, and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by Borrowers or Agent, in each
case certifying that such Lender is entitled to receive payments under this
Agreement and the Notes without deduction or withholding of any United States
federal income taxes, unless an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender advises Borrowers and Agent that it is
not capable of receiving payments without any deduction or withholding of United
States federal income tax.


     2.22 The Interim Letter of Credit.


     (a)  Payment in Certain Circumstances.  Upon the occurrence of an
Event of Default and the acceleration of the maturity of the Loans or, if
payment is not then due to the beneficiary under the Interim Letter of Credit,
Agent shall not pay the beneficiary under the Interim Letter of Credit prior to
the date for payment specified thereunder. Agent, may, however, provide for the
deposit of funds in an account to secure payment to the beneficiary, and any
funds so deposited shall be paid to such beneficiary (subject to the
satisfaction of all conditions to such payment), or returned to the Agent for
distribution to the Banks (or, if all Obligations then shall have been
indefeasibly paid in full, to the Company) if no payment to such beneficiary has
been made and if the final date available for drawings under the Interim Letter
of Credit has passed.  Each payment or deposit of funds by the Agent as provided
in this paragraph shall be treated for all purposes of this Agreement as a
drawing duly honored by the Agent under the Interim Letter of Credit and an
Advance under this Agreement.


     (b)  Termination of Credit Commitments. If for any reason the obligations
of the Lenders to make Loans hereunder shall terminate when the Interim Letter
of Credit is outstanding, Borrowers shall, in addition to their repayment
obligations hereunder, immediately deposit with Agent an amount, in cash, equal
to the face amount of the Interim Letter of Credit.


     (c)  Payment by Banks.  If Borrowers shall fail to reimburse the Agent as
and when required above for the amount of any drawing honored by the Agent under
the Interim Letter of Credit, the Agent shall promptly notify each Bank of the
unreimbursed amount of such drawing and of such Bank's respective Pro Rata Share
thereof.  Each Bank shall make available to the Agent an amount equal to its
respective Pro Rata Share of such unreimbursed drawing, in immediately available
funds, at the office of the Agent specified in such notice, not later than 12:00
P.M.



                                      -32-
   38
(Cleveland time) on the first Business Day after such Bank's receipt of such
notice from the Agent.  If any Bank fails to make available to the Agent the
amount of such Bank's Pro Rata Share of such unreimbursed drawing, the Agent
shall be entitled to recover such amount on demand from such Bank, together with
interest at the customary rate set by the Agent for the correction of errors
among banks.  Nothing in this provision shall prejudice the right of any Bank to
recover from the Agent any amounts made available by such Bank to the Agent
pursuant to this provision in the event that it is determined by a court of
competent jurisdiction that the payment with respect to the Interim Letter of
Credit by the Agent in respect of which payment was made by the Agent
constituted gross negligence or willful misconduct on the part of the Agent. The
Agent shall distribute to each other Bank which has paid all amounts payable by
it under this Section 2.22(c) with respect to the Interim Letter of Credit such
other Bank's Pro Rata Share of all payments received by the Agent from Borrowers
in reimbursement of drawings honored by the Agent under the Interim Letter of
Credit when such payments are received.


     (d)  Obligations Absolute. The obligation of Borrowers to reimburse the
Agent for drawings made under the Interim Letter of Credit and the obligations
of the Banks under Section 2.22(c) shall be unconditional and irrevocable, and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances, including, without limitation, the following:


           (i)   any lack of validity or enforceability of the Interim Letter of
     Credit;


           (ii)  the existence of any claim, setoff, defense or other right
     which Borrowers may have at any time against a beneficiary or any
     transferee of the Interim Letter of Credit (or any persons or entities for
     whom any such transferee may be acting), the Agent, any Bank or any other
     Person, whether in connection with this Agreement, the transactions
     contemplated herein or any unrelated transaction (including any underlying
     transaction between Borrowers and the beneficiary for which the Interim
     Letter of Credit was procured);


           (iii) any draft, demand, certificate or any other document presented
     under the Interim Letter of Credit proving to be forged, fraudulent,
     invalid or insufficient in any respect or any statement therein being
     untrue or inaccurate in any respect;


           (iv)  payment by the Agent under the Interim Letter of Credit against
     presentation of a demand, draft or certificate or other document which does
     not comply with the terms of the Interim Letter of Credit, provided that
     such payment does not constitute gross negligence or willful misconduct of
     the Agent;



                                      -33-
   39
           (v)  any other circumstance or occurrence whatsoever, which is
     similar to any of the foregoing; or


           (vi) the fact that a default or an Event of Default shall have
     occurred and be continuing.


           (e)  Indemnification: Nature of the Agent's Duties. In addition to
amounts payable as elsewhere provided in this Section 2.22, and without limiting
any other indemnification provided for in this Agreement, Borrowers agree to
protect, indemnify, pay and save the Agent harmless from and against any and all
claims, demands, liabilities, damages, losses, costs, charges and expenses
(including reasonable attorneys' fees) which the Agent may incur or be subject
to as a consequence, direct or indirect, of (i) the issuance of the Interim
Letter of Credit, other than as a result of the gross negligence or willful
misconduct of the Agent as determined by a court of competent jurisdiction, or
(ii) the failure of the Agent to honor a drawing under the Interim Letter of
Credit as a result of any act or omission, whether rightful or wrongful, of any
present or future de jure or de facto government or governmental authority.  As
between Borrowers and the Agent, Borrowers assume all risks of the acts and
omissions of, or misuse of the Interim Letter of Credit by, the respective
beneficiaries thereof.  In furtherance and not in limitation of the foregoing,
the Agent shall not be responsible for:  (i) the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in
connection with the application for and issuance of the Interim Letter of
Credit, even if any of the foregoing should in fact prove to be invalid,
insufficient, inaccurate, fraudulent or forged in any respect; (ii) the validity
or insufficiency of any instrument transferring or assigning or purporting to
transfer or assign the Interim Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason; (iii) the failure of the beneficiary of
the Interim Letter of Credit to comply fully with conditions required in order
to draw thereupon; (iv) the errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telecopy,
telex or otherwise, whether or not they be in cipher; (v) the errors in
interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under the Interim
Letter of Credit or any proceeds thereof; (vii) the misapplication by the
beneficiary of the Interim Letter of Credit of the proceeds of any drawing under
such Interim Letter of Credit; and (viii) for any consequences arising from
causes beyond the control of the Agent. None of the above shall affect, impair,
or prevent the vesting of any of the Agent's rights or powers hereunder.  In
determining whether to pay under the Interim Letter of Credit, the Agent shall
be responsible only to determine that the documents and certificates required to
be delivered under the Interim Letter of Credit have been delivered and that the
same comply on their face with the requirements of the Interim Letter of Credit.
Borrowers



                                      -34-
   40
shall have no obligation to indemnify the Agent in respect of any liability
incurred by the Agent arising solely out of the gross negligence or willful
misconduct of the Agent, as determined by a court of competent jurisdiction, or
out of the wrongful dishonor by the Agent of a proper demand for payment made
under the Interim Letter of Credit.

                                   ARTICLE VII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

           7.1 Acceleration. If any Default described in Section 6.7 or 6.8
occurs with respect to any Borrower, the obligations of Lenders to make Loans
hereunder shall automatically terminate and the Obligations shall immediately
become due and payable without any election or action on the part of Agent or
any Lender. If any other Default occurs, the Agent may, with the concurrence of
the Required Lenders, terminate or suspend the obligations of Lenders to make
Loans hereunder, or declare the Obligations to be due and payable or both,
whereupon the Obligations shall become immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which each Borrower
hereby expressly waives.

      If, within ten (10) days after acceleration of the maturity of the
Obligations or termination of the obligations of Lenders to make Loans hereunder
as a result of any Default (other than any Default as described in Section 6.7
or 6.8 with respect to any Borrower) and before any judgment or decree for the
payment of the Obligations due shall have been obtained or entered, each Lender
(in their sole discretion) shall so direct, Agent shall, by notice to that
Borrower, rescind and annul such acceleration and/or termination.

           7.2 Amendments & Waivers. Subject to the provisions of this Article
VII., the Required Lenders (or Agent with the consent in writing of Lenders) and
Borrowers may enter into agreements and waivers supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of Lenders or Borrowers hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement or
waiver shall, without the consent of each Lender affected thereby:

           (i)   Extend the Facility Termination Date or forgive all or any
                 portion of the principal amount of any Loan or accrued interest
                 thereon or the Commitment Fee, reduce the Applicable Margins or
                 the underlying interest rate options or extend the time of
                 payment of such interest or Commitment Fees.

           (ii)  Release any Subsidiary from the Subsidiary Guaranty.

           (iii) Increase the amount of the Commitment of any Lender hereunder.

           (iv)  Permit any Borrower to assign its rights under this Agreement.

           (v)   Amend this Section 7.2.


                                      -55-

   61
No amendment of any provision of this Agreement relating to Agent shall be
effective without the written consent of Agent.

           7.3 Preservation of Rights. No delay or omission of Lenders or Agent
to exercise any right under the Loan Documents shall impair such right or be
construed to be a waiver of any Default or an acquiescence therein, and the
making of a Loan notwithstanding the existence of a Default or the inability of
Borrowers to satisfy the conditions precedent to such Loan shall not constitute
any waiver or acquiescence. Any single or partial exercise of any such right
shall not preclude other or further exercise thereof or the exercise of any
other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Loan Documents whatsoever shall be valid unless
in writing signed by Lenders required pursuant to Section 7.2, and then only to
the extent in such writing specifically set forth. All remedies contained in the
Loan Documents or by law afforded shall be cumulative and all shall be available
to Agent and Lenders jointly until the Obligations have been paid in full.


                                  ARTICLE VIII

                               GENERAL PROVISIONS

the making of the Loans herein contemplated.

the contrary notwithstanding, no Lender shall be obligated to extend credit to
Borrowers in violation of any limitation or prohibition provided by any
applicable statute or regulation.

           8.3 Tax. Any taxes (excluding federal income taxes on the overall net
income of any Lender and taxes resulting from a Lenders failure to comply with
Section 2.21) or other similar assessments or charges made by any governmental
or revenue authority in respect of the Loan Documents shall be paid by
Borrowers, together with interest and penalties, if any.

           8.4 Heading. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

           8.5 Entire Agreement. The Loan Documents embody the entire agreement
and understanding among Borrowers, Agent and Lenders and supersede all prior
commitments, agreements and understandings among Borrowers, Agent and Lenders
relating to the subject matter thereof.

   62
           8.6 Several Obligations Benefits of This Agreement. The respective
obligations of Lenders hereunder are several and not joint and no Lender shall
be the partner or agent of any other (except to the extent to which Agent is
authorized to act as such). The failure of any Lender to perform any of its
obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns.

           8.7 Expenses; Indemnification. Borrowers shall reimburse Agent for
any costs, internal charges and out-of-pocket expenses (including, without
limitation, all expenses of Agent's due diligence investigation of Borrowers,
syndication expenses, travel expenses, reasonable fees for consultants and fees
and reasonable expenses for attorneys for Agent, which attorneys may be
employees of Agent) paid or incurred by Agent in connection with the amendment,
modification, and administration of the Loan Documents. Borrowers also agree to
reimburse Agent and Lenders for any costs, internal charges and out-of-pocket
expenses (including, without limitation, all fees and reasonable expenses for
attorneys for Agent and Lenders, which attorneys may be employees of Agent or
Lenders) paid or incurred by Agent or any Lender in connection with the
collection and enforcement of the Loan Documents (including, without limitation,
any workout). Borrowers further agree to indemnify Agent and each Lender, its
directors, officers and employees against all losses, claims, damages,
penalties, judgments, liabilities and expenses (including, without limitation,
all expenses of litigation or preparation therefor whether or not Agent or any
Lender is a party thereto) which any of them may pay or incur arising out of or
relating to this Agreement, the other Loan Documents, any Property, the
transactions contemplated hereby or the direct or indirect application or
proposed application of the proceeds of any Loan hereunder. The obligations of
Borrowers under this Section shall survive the termination of this Agreement.

           8.8 Numbers. All statements, notices, closing documents, and requests
hereunder shall be furnished to Agent with sufficient counterparts so that Agent
may furnish one to each of Lenders.

be made for Borrowers and all their Subsidiaries, including those Subsidiaries,
if any, which are unconsolidated on Borrowers' official financial statements.

           8.10 Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be


                                      -57-
   63
inoperative, unenforceable, or invalid without affecting the remaining
provisions in that jurisdiction or the operation, enforceability, or validity of
that provision in any other jurisdiction, and to this end the provisions of all
Loan Documents are declared to be severable.

           8.11 Nonliability of Lenders. The relationship between Borrowers, on
the one hand, and Lenders and Agent, on the other, shall be solely that of
borrowers and lender. Neither Agent nor any Lender shall have any fiduciary
responsibilities to Borrowers. Neither Agent nor any Lender undertakes any
responsibility to Borrowers to review or inform Borrowers of any matter in
connection with any phase of any Borrower's business or operations.

           8.12 CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN TH0SE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF OHIO, BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

           8.13 CONSENT TO JURISDICTION. EACH BORROWER HEREBY IRREVOCABLY
SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR OHIO
STATE COURT SITTING IN CUYAHOGA COUNTY IN ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO ANY LOAN DOCUMENTS AND EACH BORROWER HEREBY IRREVOCABLY AGREES
THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR
HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN

BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY ANY
BORROWER AGAINST AGENT OR ANY LENDER OR ANY AFFILIATE OF Agent OR ANY LENDER
INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED
TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN
CUYAHOGA COUNTY, OHIO.

HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR

                                      AGENT

           9.1 Appointment. National City Bank is hereby appointed Agent
hereunder and under each other Loan Document, and each of Lenders irrevocably
authorizes Agent to act as the agent of such Lender. Agent agrees to act as such

   64

Documents to be taken by Agent.

           9.3 General Immunity. Neither Agent nor any of its directors,
officers, agents or employees shall be liable to Borrowers, Lenders or any

           9.4 No Responsibility for Loans, Recitals, etc. Neither Agent nor any

creation, perfection or priority of any interest in any collateral security.
Agent shall have no duty to disclose to Lenders information that is not required
to be furnished by Borrowers to Agent at such time, but is voluntarily furnished
by Borrowers to Agent (either in its capacity as Agent or in its individual
capacity).

           9.5 Action on Instructions of Lenders. Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder and under any
other Loan Document in accordance with written instructions signed by the
Required Lenders, and such instructions and any action taken or failure to act

Agent shall be fully justified in failing or refusing to take any action

expense that it may incur by reason of taking or continuing to take any such
action.

created and its duties hereunder and under any other Loan Document.

           9.7 Reliance on Documents; Counsel. Agent shall be entitled to rely

be employees of Agent.

           9.8 Agent's Reimbursement and Indemnification. Lenders agree to
reimburse and indemnify Agent ratably in proportion to their respective
Commitments (i) for any amounts not reimbursed by Borrowers for which Agent is

kind and nature whatsoever which may be imposed on, incurred by or asserted
against Agent in any way relating to or arising out of the Loan Documents or any
other document delivered in connection therewith or the transactions
contemplated thereby, or the enforcement of any of the terms thereof or of any
such other documents, provided that no Lender shall be liable for any of the
foregoing to the extent they arise from the gross negligence or willful
misconduct of Agent. The obligations of Lenders under this Section 9.8 shall
survive payment of the Obligations and termination of this Agreement.

           9.9 Rights as a Lender. In the event Agent is a Lender, Agent shall
have the same rights and powers hereunder and under any other Loan Document as
any Lender and may exercise the same as though it were not Agent, and the term
"Lender" or "Lenders" shall, at any time when Agent is a Lender, unless the
context otherwise indicates, include Agent in its individual capacity. Agent may
accept deposits from, lend money to, and generally engage in any kind of trust,
debt, equity or other transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with Borrowers or any of their
Subsidiaries in which Borrowers or such Subsidiary is not restricted hereby from

the financial statements prepared by Borrowers and such other documents and
information as it has deemed


                                      -60-
   66
appropriate, made its own credit analysis and decision to enter into this
Agreement and the other Loan Documents. Each Lender also acknowledges that it
will, independently and without reliance upon Agent or any other Lender and

time, continue to make its own credit decisions in taking or not taking action
under this Agreement and the other Loan Documents.

           9.11 Successor Agent. Agent may resign at any time by giving written
notice thereof to Lenders and Borrowers, such resignation to be effective upon
the appointment of a successor Agent or, if no successor Agent has been
appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. Upon any such resignation, Lenders shall have the right to
appoint, on behalf of Borrowers and Lenders, a successor Agent. If no successor
Agent shall have been so appointed by Lenders within thirty days after the
resigning Agent's giving notice of its intention to resign, then the resigning
Agent may appoint, on behalf of Borrowers and Lenders, a successor Agent. If

Agent, the provisions of this Article X shall continue in effect for the benefit
of such Agent in respect of any actions taken or omitted to be taken by it while
it was acting as Agent hereunder and under the other Loan Documents.


                                    ARTICLE X

                            SETOFF; RATABLE PAYMENTS

           10.1 Setoff. In addition to, and without limitation of, any rights of
Lenders under applicable law, if any Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender to
or for the credit or account of Borrowers may be offset and applied toward the
payment of the Obligations owing to such Lender, whether or not the Obligations,
or any part hereof, shall then be due.


                                      -61-
   67
           10.2 Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans in a greater proportion than that received
by any other Lender, such Lender agrees, promptly upon demand, to purchase a
portion of the Loans held by the other Lenders so that after such purchase each
Lender will hold its ratable proportion of Loans. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Lender agrees, promptly upon demand, to
take such action necessary such that all Lenders share in the benefits of such
collateral ratably in proportion to their Loans. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.


                                   ARTICLE XI

                BENEFIT OF AGREEMENT; ASSIGNMENT; PARTICIPATIONS

           11.1 Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of Borrowers and
Lenders and their respective successors and assigns, except that (i) Borrowers
shall not have the right to assign their rights or obligations under the Loan
Documents and (ii) any assignment by any Lender must be made in compliance with
Section 11.3. Notwithstanding clause (ii) of this Section, any Lender may at any
time, without the consent of Borrowers or Agent, assign all or any portion of
its rights under this Agreement and its Notes to a Federal Reserve Bank;
provided, however, that no such assignment shall release the transferor Lender
from its obligations hereunder. Agent may treat the payee of any Note as the
owner thereof for all purposes hereof unless and until such payee complies with
Section 11.3 in the case of an assignment thereof or, in the case of any other
transfer, a written notice of the transfer is filed with Agent. Any assignee or
transferee of a Note agrees by acceptance thereof to be bound by all the terms
and provisions of the Loan Documents. Any request, authority or consent of any
Person, who at the time of making such request or giving such authority or
consent is the holder of any Note, shall be conclusive and binding on any
subsequent holder, transferee or assignee of such Note or of any Note or Notes
issued in exchange therefor.

           11.2 Participations.

           11.2.1 Permitted Participants; Effect. Any Lender may, in the
      ordinary course of its business and in accordance with applicable law, at
      any time sell to one or more banks, financial institutions, pension funds,
      or any other funds or entities participating interests in any Loan owing
      to such Lender, any Note held by such Lender, any Commitment of such


                                      -62-
   68
      Lender or any other interest of such Lender under the Loan Documents. In
      the event of any such sale by a Lender of participating interests to a
      Participant, such Lender's obligations under the Loan Documents shall
      remain unchanged, such Lender shall remain solely responsible to the other
      parties hereto for the performance of such obligations, such Lender shall
      remain the holder of any such Note for all purposes under the Loan
      Documents, all amounts payable by Borrowers under this Agreement shall be
      determined as if such Lender had not sold such participating interests,
      and Borrowers and Agent shall continue to deal solely and directly with
      such Lender in connection with such Lender's rights and obligations under
      the Loan Documents.

           11.2.2 Voting Rights. Each Lender shall retain the sole right to
      approve, without the consent of any Participant, any amendment,
      modification or waiver of any provision of the Loan Documents other than
      any amendment, modification or waiver with respect to any Loan or
      Commitment in which such Participant has an interest which forgives
      principal, interest or fees or reduces the interest rate or fees payable
      with respect to any such Loan or Commitment or postpones any date fixed
      for any regularly scheduled payment of principal of, or interest or fees
      on, any such Loan or Commitment or releases any Subsidiary from the
      Subsidiary Guaranty.

           11.2.3 Benefit of Setoff. Each Borrower agrees that each Participant
      shall be deemed to have the right of Setoff provided in Section 10.1 in
      respect of its participating interest in amounts owing under the Loan
      Documents to the same extent as if the amount of its participating
      interest were owing directly to it as a Lender under the Loan Documents,
      provided that each Lender shall retain the right of setoff provided in
      Section 10.1 with respect to the amount of participating interests sold to
      each Participant. Lenders agree to share with each Participant, and each
      Participant, by exercising the right of setoff provided in Section 10.1,
      agrees to share with each Lender, any amount received pursuant to the
      exercise of its right of setoff, such amounts to be shared in accordance
      with Section 10.2 as if each Participant were a Lender.

           11.3 Assignments.

           11.3.1 Permitted Assignments. Any Lender may, in the ordinary course
      of its business and in accordance with applicable law, at any time assign
      to one or more banks, financial institutions, pension funds, or any other
      funds or entities ("Purchasers") all or any portion of its rights and
      obligations under the Loan Documents. Such assignment shall be
      substantially in the form of Exhibit H hereto or in such other form as may
      be agreed to by the parties thereto. The consent of Agent shall be
      required prior to an assignment


                                      -63-
   69
      becoming effective with respect to a Purchaser which is not a Lender or an
      Affiliate thereof. Such consent shall not be unreasonably withheld.

           11.3.2 Prior Consent. Notwithstanding Section 11.3.1, Lenders may not
      assign rights and obligations under the Loan Documents to a Purchaser
      without the prior written consent of Borrowers if any of the following
      would occur: (i) an assignment of less than five (5%) of the Aggregate
      Commitment as of the date of such assignment, (ii) the proposed purchaser
      is a financial institution not organized under the laws of a state or of
      the United States (unless such institution is an affiliate of the
      transferring Lender), or (iii) such transfer would result in Borrowers
      incurring increased payments pursuant to Section 2.11; provided, however,
      that, if at the time of the proposed assignment either Borrower is the
      subject of a proceeding referenced in Section 6.7 or 6.8, or any Default
      shall have occurred, the Borrowers consent shall not be required and any
      Lender may consummate an assignment notwithstanding the requirements of
      clauses (i), (ii) or (iii) of this Section 11.3.2.

           11.3.3 Effective Date. Upon (i) delivery to Agent of a notice of
      assignment, substantially in the form attached as Exhibit 1 to Exhibit H
      hereto (a "Notice of Assignment"), together with any consents required by
      Section 11.3.2, and (ii) payment of a $2,500 fee to Agent for processing
      such assignment (provided, however, that if such assignment shall be made
      to an Affiliate of Lender, then Lender shall not be required to pay such
      fee to Agent), such assignment shall become effective on the effective
      date specified in such Notice of Assignment. The Notice of Assignment
      shall contain a representation by the Purchaser to the effect that none of
      the consideration used to make the purchase of the Commitment and Loans
      under the applicable assignment agreement are "plan assets" as defined
      under ERISA and that the rights and interests of the Purchaser in and
      under the Loan Documents will not be "plan assets" under ERISA. On and
      after the effective date of such assignment, such Purchaser shall for all
      purposes be a Lender party to this Agreement and any other Loan Document
      executed by Lenders and shall have all the rights and obligations of a
      Lender under the Loan Documents, to the same extent as if it were an
      original party hereto, and no further consent or action by the Borrower,
      Lenders or Agent shall be required to release the transferor Lender with
      respect to the percentage of the Aggregate Commitment and Loans assigned
      to such Purchaser. Upon the consummation of any assignment to a Purchaser
      pursuant to this Section 11.3.2, the transferor Lender, Agent and
      Borrowers shall make appropriate arrangements so that replacement Notes
