         Agent by 1:00 p.m. (Cleveland, Ohio time) on the same day such
         telephonic Credit Request was given and (II) that the other
         requirements of this Section are satisfied. The Agent may rely on such
         telephonic Credit Request to the same extent that the Agent may rely on
         a written Credit Request. The

                                       19
<PAGE>   28

         Borrower shall bear all risks related to the giving of a Credit Request
         by the Borrower whether given telephonically or by such other method of
         transmission as the Borrower shall elect.

                  (b) REQUESTS FOR REVOLVING CREDIT BORROWING DEEMED GIVEN. The
         Borrower shall be deemed to have made a request for a Borrowing (a
         "Deemed Credit Request"), which Deemed Credit Request shall be deemed
         to be irrevocable, upon the occurrence of any of the following and the
         Banks agree that on the specified date of such occurrence, the Banks
         will make the requested Loans pursuant to the Deemed Credit Request and
         that the Banks' obligation to make such Loans is absolute and
         unconditional and shall not be affected by any event or circumstance
         whatsoever, including the occurrence of any Potential Default or Event
         of Default hereunder or the failure of any condition precedent set
         forth in Section 0 of this Agreement to be satisfied and each such
         payment shall be made without any offset, abatement, withholding or
         reduction whatsoever:

                           (i) LETTER OF CREDIT DRAWING. As specified in Section
                  0 of this Agreement, upon a drawing under a Letters of Credit,
                  the Borrower shall be deemed to have made a request for an
                  Alternate Base Rate Borrowing in an amount equal to the amount
                  necessary either to reimburse the Letter of Credit Bank for
                  such drawing upon the Letter of Credit together with accrued
                  interest thereon or, if reimbursement of the Letter of Credit
                  Bank is made by the Banks for any reason, reimburse the Banks
                  for such payment.

                           (ii) PAYMENT OF INTEREST AND OBLIGATIONS. Unless
                  payment is otherwise made by the Borrower, upon any such
                  interest or fee hereunder becoming due without payment by the
                  Borrower, the Borrower shall be deemed to have made a request
                  for an Alternate Base Rate Borrowing in an amount equal to the
                  amount necessary to pay such interest or fee.

Each Bank acknowledges and agrees that its obligation to participate in and make
Loans comprising a Borrowing pursuant to a Deemed Credit Request is absolute and
unconditional and shall not be affected by any event or circumstance whatsoever,
including the occurrence of any Potential Default or Event of Default hereunder
or the failure of any condition precedent set forth in Section 0 of this
Agreement to be satisfied at the time of the making of such Deemed Credit
Request, and each Loan made by a Bank in satisfaction of its obligation shall be
made without any offset, abatement, withholding or reduction whatsoever.

         2.3      FUNDING OF REVOLVING CREDIT LOANS. The Agent shall notify each
Bank of such Credit Request promptly on the date received by telecopy, telephone
or similar form of transmission. Each Bank shall, before 3:00 p.m. (Cleveland,
Ohio time) on the date of each Revolving Credit Borrowing requested, make
available to the Agent, in immediately available funds at the account of the
Agent maintained at the Payment Office of the Agent, such Bank's

                                       20
<PAGE>   29

Ratable Portion of the Revolving Credit Borrowing. On the date requested by the
Borrower for a Revolving Credit Borrowing, after the Agent's receipt of the
funds representing a Bank's Ratable Portion of such Revolving Credit Borrowing
and subject to the terms of this Agreement and the Borrower's fulfillment of the
conditions set forth in Section 0 of this Agreement, the Agent will make such
Revolving Credit Loan of such Bank available to the Borrower in immediately
available funds, by wire transfer or intrabank transfer: (A) to the Operating
Account or (B such other account of the Borrower as the Agent and the Borrower
shall have agreed upon from time to time in writing.

                  (a) DISBURSEMENT OF FUNDS RECEIVED. On the date requested by
         the Borrower for a Revolving Credit Borrowing, after the Agent's
         receipt of the funds representing a Bank's Ratable Portion of such
         Revolving Credit Borrowing and subject to the terms and conditions set
         forth in this Agreement, the Agent shall make such Revolving Credit
         Advance of such Bank available to the Borrower, in immediately
         available funds, by wire transfer or intrabank transfer to the
         Operating Account.

         2.4      AVAILABILITY OF FUNDS. Unless the Agent shall have received
notice from a Bank on a Business Day prior to the date (or, in the case of
Alternate Base Rate Loans, prior to the time) of any Revolving Credit Borrowing
that such Bank will not make available to the Agent such Bank's Ratable Portion
of the Revolving Credit Borrowing, the Agent may assume that such Bank has made
its Ratable Portion of the Revolving Credit Borrowing available to the Agent on
the date of the Revolving Credit Borrowing in accordance with Section 0 of this
Agreement. In reliance upon such assumption, the Agent may, but shall not be
obligated to, make available to the Borrower on such date, a portion of the
Revolving Credit Borrowing corresponding to such Bank's Ratable Portion. Any
disbursement by the Agent in reliance on such assumption shall be deemed to be
an advance of a Revolving Credit Loan by such Bank.

         2.5      FAILURE OF BANK TO FUND. If and to the extent that any Bank
shall not have made available to the Agent such Bank's Ratable Portion of any
Revolving Credit Borrowing, such Bank and the Borrower severally agree to repay
to the Agent, immediately upon demand by the Agent, an amount equal to such
Bank's Ratable Portion of such Revolving Credit Borrowing, as the case may be,
together with interest thereon for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent, at:
(a) in the case of the Bank, (i) Federal Funds Rate for the first three (3) days
from and after the date of the Revolving Credit Borrowing and (ii) thereafter,
at the Interest Rate then applicable to Alternate Base Rate Loans and (b) in the
case of the Borrower, the interest rate applicable at the time to Alternate Base
Rate Loans.

                  (a) PAYMENT CONSTITUTING RATABLE PORTION. If such Bank pays to
         the Agent the Bank's Ratable Portion of such Revolving Credit Borrowing
         prior to repayment of such amount by the Borrower, the amount so repaid
         shall constitute such Bank's Ratable Portion of such Revolving Credit
         Borrowing and the Borrower shall have no further obligation to make the
         payment required by this Section.

                                       21
<PAGE>   30

                  (b) TREATMENT OF DEFAULTING BANK. The Agent shall not be
         obligated to transfer to a defaulting Bank any payments made by the
         Borrower to the Agent for the benefit of such defaulting Bank if such
         Bank has not made available to the Agent such Bank's Ratable Portion of
         any Revolving Credit Borrowing advanced pursuant to this Agreement.
         Until the earlier of such defaulting Bank's cure of such failure or the
         termination of the Commitments, all amounts repaid to the Agent by the
         Borrower which would otherwise be required to be applied to such Bank's
         Ratable Portion of the Obligations shall be advanced to the Borrower by
         the Agent on behalf such defaulting Bank to cure, in full or in part,
         the failure by such Bank, but shall nevertheless be deemed to have been
         paid to such defaulting Bank in satisfaction of the Obligations to
         which such payment would otherwise have been applied. Notwithstanding
         anything contained herein to the contrary, no such defaulting Bank
         shall have any voting or consent rights under or with respect to the
         Loan Documents or constitute a "Bank" (or be included in the
         calculation of "Required Banks" hereunder) for any voting or consent
         rights under or with respect to any Loan Document. The terms of this
         Section 0 shall: (i) remain effective with respect to such defaulting
         Bank until such time as the defaulting Bank shall no longer be in
         default of any of its obligations under this Agreement and (ii) shall
         not relieve or excuse the performance by the Borrower of any of its
         duties or obligations hereunder.

                  (c) CONTINUING BORROWER OBLIGATION. Failure of any Bank to
         fund its Ratable portion of any Borrowing shall not relieve or excuse
         the performance by the Borrower of any of its duties or obligations
         hereunder.

                  (d) CONTINUING BANK OBLIGATION TO FUND. It is understood that:
         (i) a Bank shall not be responsible for any failure by any other Bank
         to perform its obligation to make any Loans hereunder, (ii) the
         Revolving Credit Commitment of a Bank shall not be increased or
         decreased as a result of any failure by any other Bank to perform its
         obligation to make any Loans hereunder, (iii) failure by any Bank to
         perform its obligation to make any Loans hereunder shall not excuse any
         other Bank from its obligation to make any Revolving Credit Loans
         hereunder, and (iv) the obligations of each Bank hereunder shall be
         several, not joint and several.

         2.6      REPAYMENTS AND PREPAYMENTS; REDUCTION OF COMMITMENTS,
EXTENSION OF COMMITMENTS.

                  (a) REPAYMENT. The Borrower shall repay to the Agent, for the
         account of the Banks, the outstanding principal amount of the Revolving
         Credit Loans on the Revolving Credit Termination Date in accordance
         with Section 0(a).

                  (b) MANDATORY PREPAYMENT OF REVOLVING CREDIT LOANS. If, on any
         Business Day, (x) the sum of: (A) the aggregate Revolving Credit Loans
         outstanding at

                                       22
<PAGE>   31

         such time plus (B) the aggregate LC Exposure of the Banks outstanding
         at such time exceeds (y) the aggregate Revolving Credit Commitments of
         all of the Banks then in effect, then the Borrower shall on such day
         prepay to the Agent for the account of the Banks an aggregate principal
         amount of such Revolving Credit Loans in an amount at least equal to
         such excess plus any amounts required pursuant to the provisions of
         Section 0 of this Agreement.

                  (c) MANDATORY REDUCTION OF REVOLVING CREDIT COMMITMENT. The
         Borrower shall apply all Net Proceeds acquired in connection with
         transactions permitted by this Agreement promptly upon receipt thereof
         to prepay the Revolving Credit Loans outstanding at the time of such
         receipt and to permanently reduce the Revolving Credit Commitments
         (rounded down to the nearest One Hundred Thousand Dollars ($100,000)
         amounts in excess of such rounded amount shall be applied to the
         outstanding Revolving Credit Loans only): provided, however, that the
         Borrower shall not be permitted at any time to reduce the Revolving
         Credit Commitments to an amount less than the aggregate LC Exposure of
         the Banks outstanding at such time. In the event that the reduction in
         the Revolving Credit Commitments required by this Section 0 would cause
         the remaining Revolving Credit Commitments to be less than the LC
         Exposure of the Banks after giving effect to such reduction, the Agent
         shall hold such excess fund in a non-interest bearing account until
         such time that the requirements of the immediately preceding sentence
         shall not be violated. Each reduction in the aggregate Revolving Credit
         Commitments hereunder shall be made among the Banks ratably in
         accordance with their Revolving Credit Commitments. On the date of each
         reduction, the Borrower shall pay to the Agent for the account of the
         Banks (x) the commitment fees and interest accrued through the date of
         such reduction in respect of the aggregate Revolving Credit Commitments
         and (y) any amounts required pursuant to the provisions of Section 0 of
         this Agreement. Any reduction in the Revolving Credit Commitments shall
         be a permanent reduction and no amount in excess of such reduced
         commitment may be borrowed or reborrowed.

                  (d) VOLUNTARY REDUCTION OF REVOLVING CREDIT COMMITMENT. Upon
         three (3) Business Days prior written notice to the Agent, the Borrower
         may in accordance with the terms of this Agreement request that the
         Banks permanently reduce, in whole or in part, the aggregate Revolving
         Credit Commitment. Each reduction shall be subject to the following:
         (i) each such reduction shall be in an aggregate principal amount of
         not less than Five Million Dollars ($5,000,000) or any integral
         multiple of One Million Dollars ($1,000,000) in excess thereof, (ii)
         the Borrower shall not be permitted to reduce the aggregate Revolving
         Credit Commitments unless, concurrently with any reduction, the
         Borrower shall make a principal payment on each Bank's then outstanding
         Revolving Credit Loans in an amount equal to the excess, if any, of (A)
         the sum of such Revolving Credit Loans and aggregate LC Exposure over
         (B) the Revolving Credit Commitment of such Bank as so reduced and
         (iii) the Borrower shall not be permitted at any time to reduce the
         Revolving Credit Commitments to an amount less than the aggregate LC
         Exposure of the Banks outstanding at such time. Each reduction in the
         aggregate

                                       23
<PAGE>   32

         Revolving Credit Commitments hereunder shall be made among the Banks
         ratably in accordance with their Revolving Credit Commitments. On the
         date of each reduction, the Borrower shall pay to the Agent for the
         account of the Banks (x) the commitment fees and interest accrued
         through the date of such reduction in respect of the aggregate
         Revolving Credit Commitments and (y) any amounts required pursuant to
         the provisions of Section 0 of this Agreement. Any reduction in the
         Revolving Credit Commitments shall be a permanent reduction and no
         amount in excess of such reduced commitment may be borrowed or
         reborrowed.

                  (e) PERMITTED PREPAYMENTS. The Borrower may prepay all or any
         part of Revolving Credit Loans by giving notice to the Agent for the
         account of the Banks stating the proposed date of prepayment, the Type
         of Borrowing being prepaid and the aggregate principal amount of the
         prepayment not later than 12:00 noon (Cleveland, Ohio time) on the
         Business Day immediately preceding the Business Day on which such
         prepayment is to be made. Upon such notice, the Borrower shall: (A) in
         respect of Alternate Base Rate Loans comprising part of the same
         Revolving Credit Borrowing, prepay the outstanding aggregate principal
         amount thereof in whole or ratably in part and (B) in respect of LIBOR
         Rate Loans comprising part of the same Revolving Credit Borrowing,
         prepay the outstanding aggregate principal amount thereof in whole and
         the interest accrued to the date of such prepayment on the principal
         amount of such Borrowing so prepaid; provided, however, that: (I) each
         partial prepayment of Alternate Base Rate Loans shall be (x) in an
         aggregate principal amount of One Hundred Thousand Dollars ($100,000)
         or any multiple thereof or (y) in an amount equal to the aggregate
         principal amount of Alternate Base Rate Loans then outstanding, (II)
         each partial prepayment of LIBOR Rate Loans shall be (a) in an
         aggregate principal amount not less than One Million Dollars
         ($1,000,000), or an integral multiple of One Hundred Thousand Dollars
         ($100,000) in excess thereof or (b) in an amount equal to the aggregate
         principal amount of LIBOR Rate Loans then outstanding, and (III) any
         prepayment of any LIBOR Rate Loans made on other than the last day of
         an Interest Period shall obligate the Borrower to reimburse the Bank in
         respect thereof pursuant to Section 0 of this Agreement.

                  (f) EXTENSION OF COMMITMENT PERIOD. During the thirty (30) day
         period following delivery by the Borrower pursuant to Section 0 of this
         Agreement of its consolidated financial statements for its Fiscal Year
         ending December 31, 1998, and annually thereafter during the thirty
         (30) day period following delivery by the Borrower of its consolidated
         financial statements pursuant to Section 0, the Borrower may request
         the Agent to determine if all of the Banks are then willing to extend
         the Revolving Credit Termination Date for a single additional year. If
         the Borrower so requests the Agent will advise the Banks. If all of the
         Banks in their sole discretion are willing to extend the Revolving
         Credit Termination Date, the Borrower, the Agent and the Banks shall
         execute a definitive written amendment extending the Revolving Credit
         Termination Date. No extension shall be effective for any purpose
         unless such definitive written instrument is signed by all of the Banks
         and delivered within sixty (60) days following the notice from

                                       24
<PAGE>   33

         the Agent to the Banks that the Borrower has requested such an
         extension. No Bank shall be obligated to grant the Borrower any such
         extension, and unanimous written consent of all the Banks shall be
         required to extend the Revolving Credit Termination Date. In the event
         of the failure of any of the Banks to so respond affirmatively or
         negatively in writing within such sixty (60) day period, such request
         for extension shall be deemed to have been denied.

         2.7      RATE CONVERSION AND RATE CONTINUATION. The Borrower shall have
the right to convert or continue any Revolving Credit Borrowing as a LIBOR Rate
Borrowing or an Alternate Base Rate Borrowing, upon request delivered by the
Borrower to the Agent not later than 12:00 noon (Cleveland time): (a) on the
Business Day that Borrower desires to convert any LIBOR Rate Borrowing into an
Alternate Base Rate Borrowing, (b) three Business Days prior to the Business Day
on which the Borrower desires to convert any Alternate Base Rate Borrowing into
a LIBOR Rate Borrowing for a given Interest Period, (c) three Business Days
prior to the Business Day on which Borrower desires to continue any LIBOR Rate
Borrowing as a LIBOR Rate Borrowing for an additional Interest Period of the
same duration, and (d) three Business Days prior to the Business Day on which
Borrower desires to convert any LIBOR Rate Borrowing having a particular
Interest Period into a LIBOR Rate Borrowing having a different permissible
Interest Period; provided, however, that each such Rate Conversion or Rate
Continuation shall be subject to the following:

                  (i) each Rate Conversion or Rate Continuation shall be made
         among the Banks based upon such Bank's Ratable Portion of such
         converted or continued Revolving Credit Borrowing;

                  (ii) if less than all the outstanding principal amount of a
         Revolving Credit Borrowing is converted or continued, the aggregate
         principal amount of such Revolving Credit Borrowing converted or
         continued shall be: (A) in the case of a LIBOR Rate Borrowing, not less
         than One Million Dollars ($1,000,000), or an integral multiple of One
         Hundred Thousand Dollars ($100,000) in excess thereof and (B) in the
         case of an Alternate Base Rate Borrowing, One Hundred Thousand Dollars
         ($100,000);

                  (iii) each Rate Conversion or Rate Continuation shall be
         effected as if each Bank were applying the proceeds of Loans resulting
         from such Rate Conversion or Rate Continuation to Loans being converted
         or continued, as the case may be, and the accrued interest on any such
         Loans (or portion thereof) being converted or continued shall be paid
         to the Agent on behalf of each Bank by the Borrower at the time of such
         Rate Conversion or Rate Continuation;

                  (iv) LIBOR Rate Loans shall not be converted or continued at a
         time other than the end of an Interest Period applicable thereto unless
         the Borrower shall pay to the Agent for the benefit of the Banks, upon
         demand, any amounts due to any of the Banks pursuant to Section 0.4 of
         this Agreement;

                                       25
<PAGE>   34

                  (v) a Revolving Credit Borrowing may not be converted into or
         continued as a LIBOR Rate Borrowing if the Interest Period applicable
         thereto will expire less than one month prior to the Revolving Credit
         Termination Date;

                  (vi) after and during the continuance of a Potential Default,
         and after the occurrence of an Event of Default which has not been
         waived or otherwise consented to by the Required Banks, a Revolving
         Credit Borrowing may not be converted or continued as a LIBOR Rate
         Borrowing; and

                  (vii) any LIBOR Rate Borrowing that cannot be continued as a
         LIBOR Rate Borrowing by reason of clause (iv), (v), (vi) or (vi) of
         this definition shall be automatically converted at the end of the
         Interest Period in effect for each LIBOR Rate Borrowing into an
         Alternate Base Rate Borrowing.

Each such request for a conversion or continuation (a "Rate
Conversion/Continuation Request") in respect of a Revolving Credit Borrowing
shall be transmitted by the Borrower to the Agent by telecopier, telex or cable
(in the case of telex or cable, confirmed in writing prior to the effective date
of the Rate Conversion or Rate Continuation requested), in substantially the
form of Exhibit C hereto. The Rate Conversion/Continuation Request shall
specify: (A) the identity and amount of the Loans comprising a Revolving Credit
Borrowing that the Borrower requests be converted or continued, (B) the Type of
Loans into which such Loans are to be converted or continued, (C) if such notice
requests a Rate Conversion, the date of the Rate Conversion (which shall be a
Business Day) and (D) in the case of a Revolving Credit Borrowing converted into
or continued as a LIBOR Rate Borrowing, the Interest Period for such LIBOR Rate
Loans. The Borrower may make Rate Conversion/Continuation Requests
telephonically so long as written confirmation of such Revolving Credit
Borrowing is received by the Agent by 1:00 p.m. (Cleveland, Ohio time) on the
same day of such telephonic Rate Conversion/Continuation Request. The Agent may
rely on such telephonic Rate Conversion/Continuation Request to the same extent
that the Agent may rely on a written Rate Conversion/Continuation Request. Each
Rate Conversion/Continuation Request, whether telephonic or written, shall be
irrevocable and binding on the Borrower and subject the Borrower to the
indemnification provisions of Section 0 of this Agreement. The Borrower shall
bear all risks related to giving any Rate Conversion/Continuation Request
telephonically or by such other method of transmission as Borrower shall elect.

         2.8      LETTERS OF CREDIT. Subject to the terms and conditions set
forth in this Agreement, the Letter of Credit Bank agrees, at any time and from
time to time, from and including the Closing Date but in no event after the
thirtieth calendar day immediately preceding the Revolving Credit Termination
Date, to issue and deliver, or to extend the expiration of, Letters of Credit
for the account of the Borrower; provided, however, that, the aggregate LC
Exposure of the Banks shall not at any time exceed the lesser of: (x) Ten
Million Dollars ($10,000,000) outstanding at any time and (y) the difference
between (I) the aggregate Revolving

                                       26
<PAGE>   35

Credit Commitments of the Banks as then in effect and (II) the sum of (a) the
aggregate outstanding Revolving Credit Loans of the Banks at such time plus (b)
the aggregate LC Exposure of the Banks at such time.

                  (a) TERM; FORM AND CONDITIONS OF LETTERS OF CREDIT. Each
         Letter of Credit shall be issued in such form as the Letter of Credit
         Bank may reasonably require subject to the Uniform Customs and
         Practices for Documentary Credits (1993 Revision), International
         Chamber of Commerce Publication No. 500, and any subsequent revisions
         thereof. Each Letter of Credit shall: (A) permit drawings upon
         presentation of one or more sight drafts and such other documents as
         specified by the Borrower in the Credit Request delivered pursuant to
         Section 0 of this Agreement and agreed to by the Letter of Credit Bank,
         which drawings shall occur on or prior to the applicable expiration
         date of such Letter of Credit, (B) by its terms expire not later than
         the earlier of one (1) year after the date of the Letter of Credit or
         the third (3rd) Business Day prior to the Revolving Credit Termination
         Date and (C) by its terms provided for payment of drawings in Dollars.

                  (b) REQUESTS FOR LETTERS OF CREDIT. Letters of Credit shall be
         issued upon request given by the Borrower to the Agent not later than
         12:00 noon (Cleveland, Ohio time) three (3) Business Days prior to the
         specified date for the issuance of the requested Letter of Credit. Each
         such request for a Letter of Credit shall be made in the form of a
         Credit Request transmitted by the Borrower to the Agent by telecopier,
         telex or cable (in the case of telex or cable, confirmed in writing
         prior to the date of the requested issuance of the Letter of Credit),
         specifying with respect to each Letter of Credit requested: (i) the
         face amount thereof, (ii) the beneficiary, (iii) the intended date of
         issuance, (iv) the terms of the Letter of Credit, and shall be promptly
         forwarded by the Agent to the Letter of Credit Bank. Concurrently with
         each Credit Request requesting a Letter of Credit, the Borrower shall
         execute and deliver to the Letter of Credit Bank a Reimbursement
         Agreement, in the Letter of Credit Bank's then standard form of
         application for and reimbursement agreement with respect to letters of
         credit (such documents being hereinafter collectively referred to as a
         "Reimbursement Agreement"); provided, however, that in the event of any
         conflict between the provisions of any such Reimbursement Agreement and
         this Agreement, the provisions of this Agreement shall govern.

                  (c) PARTICIPATION BY BANKS IN LETTERS OF CREDIT. By the
         issuance of a Letter of Credit by the Letter of Credit Bank and without
         further action on the part of the Letter of Credit Bank or any Bank,
         the Letter of Credit Bank hereby grants to each Bank, and each Bank
         hereby acquires from the Letter of Credit Bank, a participation in each
         Letter of Credit equal to such Bank's Ratable Portion, effective on the
         date of the issuance of each Letter of Credit. In consideration, each
         Bank hereby absolutely and unconditionally agrees to pay to the Agent
         for the account of such Letter of Credit Bank such Bank's Ratable
         Portion of each disbursement made by such Letter of Credit Bank in
         respect of such Letter of Credit and not reimbursed by the Borrower as
         hereinafter provided or not reimbursed by reason of the illegality of
         such reimbursement, or any reimbursement payment required to be
         refunded to the Borrower for any reason. Each Bank acknowledges and
         agrees that its obligation to acquire risk participations pursuant to
         this Section 0 is absolute and unconditional and shall not be affected
         by any event or circumstance whatsoever, including the occurrence of
         any Potential Default or Event of Default hereunder or the failure of
         any condition precedent set forth in Section 0 of this Agreement to be
         satisfied and each payment in satisfaction thereof shall be made
         without any offset, abatement, withholding or reduction whatsoever;
         provided, however, that the foregoing shall not be construed to excuse
         the Letter of Credit Bank from liability to any Bank to the extent of
         any direct damages (as opposed to consequential damages, claims in
         respect of which are hereby waived by each of the Banks to the fullest
         extent permitted by applicable Law) suffered by such Bank that are
         caused by such Letter of Credit Bank's gross negligence or wilful
         misconduct.

                  (d) REIMBURSEMENT; INTEREST. The Borrower agrees that whenever
         there is a drawing on a Letter of Credit issued by the Letter of Credit
         Bank, the Borrower shall pay to the Agent on the date of such drawing,
         an amount equal to such drawing. The Agent shall promptly remit any
         such payment to the Letter of Credit Bank. If there is a drawing on a
         Letter of Credit, then, unless the Borrower shall reimburse such amount
         in full on such date, the unpaid amount thereof shall bear interest for
         the account of the Letter of Credit Bank for each day from and
         including the date of such drawing, to but excluding the earlier of the
         date of reimbursement or the date on which such drawing is reimbursed
         by a Revolving Credit Borrowing, at the rate per annum that would apply
         to such amount if such amount were an Alternate Base Rate Loan by a
         Bank.

                  (e) FAILURE TO REIMBURSE. In the event that the Borrower fails
         to make a timely reimbursement, together with any interest thereon, to
         the Agent on the date of any drawing on a Letter of Credit pursuant to
         this Section, such failure shall constitute a Deemed Credit Request
         requesting an Alternate Base Rate Loan in an aggregate amount equal to
         the amount reimbursable to the Letter of Credit Bank plus any interest
         thereon. The Agent shall disburse all such loan proceeds directly to
         the Letter of Credit Bank to satisfy the Borrower's aforesaid
         reimbursement liability. The obligations of the Banks to the Agent
         under this Section are in addition to and not in limitation of the
         obligations of the Banks under Section 0 of this Agreement. In the
         event that an Loan cannot be legally

                                       28
<PAGE>   37

         made pursuant to this Section 0 for any reason, each of the Banks shall
         reimburse the Letter of Credit Bank in an amount equal to such Bank's
         Ratable Portion of the drawing on the Letter of Credit.

                  (f) OBLIGATIONS ABSOLUTE. The obligation of the Borrower to
         reimburse the Letter of Credit Bank shall, in each case, be absolute
         and unconditional and shall be performed under all circumstances
         including, without limitation: (i) any lack of validity or
         enforceability of any Letter of Credit, (ii) the existence of any
         claim, offset, defense or other right that the Borrower may have
         against the beneficiary of any Letter of Credit or any successor in
         interest thereto, (iii) the existence of any claim, offset, defense or
         other right that any Bank or the Agent may have against the Borrower or
         against the beneficiary of any Letter of Credit or against any
         successor in interest thereto, (iv) the existence of any fraud or
         misrepresentation in the presentment of any draft or other item drawn
         and paid under any Letter of Credit by any person other than the Letter
         of Credit Bank, (v) any payment of any draft or other item by the
         Letter of Credit Bank which does not strictly comply with the terms of
         any Letter of Credit issued by the Letter of Credit Bank, so long as,
         in each case, such payment shall not have constituted gross negligence
         or willful misconduct on the part of the Letter of Credit Bank, (vi)
         any improper use which may be made of the Letter of Credit or any
         improper acts or omissions of any beneficiary or transferee of the
         Letter of Credit in connection therewith, (vii) any statement or any
         other documents presented under any Letter of Credit proving to be
         insufficient, forged, fraudulent or invalid in any respect or any
         statement therein being untrue or inaccurate in any respect whatsoever,
         (viii) the insolvency of any Person issuing any documents in connection
         with the Letter of Credit, (ix) any irregularity in the transaction
         with respect to which a Letter of Credit is issued, including any fraud
         by the beneficiary or any transferee of such Letter of Credit, (x) any
         errors, omissions, interruptions or delays in transmission or delivery
         of any messages, (xi) any act, error, neglect or default, omission,
         insolvency or failure of business of any of the correspondents of the
         Letter of Credit Bank, or (xii) any other circumstances arising from
         causes beyond the control of the Letter of Credit Bank.

                  (g) LIABILITY OF LETTER OF CREDIT BANK. It is expressly
         understood and agreed that the absolute and unconditional obligation of
         the Borrower hereunder to reimburse disbursements in respect of Letters
         of Credit issued by a Letter of Credit Bank shall not be construed to
         excuse a Letter of Credit Bank from liability to the Borrower to the
         extent of any direct damages (as opposed to consequential damages,
         claims in respect of which are hereby waived by the Borrower to the
         extent permitted by applicable Law) suffered by the Borrower or any
         Subsidiary of the foregoing that are caused by the gross negligence or
         willful misconduct of the Letter of Credit Bank in determining whether
         drafts and other documents presented under a Letter of Credit comply
         with the terms thereof. The parties agree that the Letter of Credit
         Bank may accept documents that appear on their face to be in order,
         without responsibility for further investigation, regardless of any
         notice or information to the contrary, and may make payment upon

                                       29
<PAGE>   38

         presentation of documents that appear on their face to be in
         substantial compliance with the terms of such Letter of Credit;
         provided, however, that the Letter of Credit Bank shall have the right
         in its sole discretion to decline to accept such documents and to
         decline to make such payment if such documents are not in strict
         compliance with the terms of such Letter of Credit. In making any
         payment under any Letter of Credit, the Letter of Credit Bank's (i)
         exclusive reliance on the documents, appearing on their face to be in
         order, as well as signatures and endorsements presented to it under
         such Letter of Credit, in each case as to any and all matters set forth
         therein, including reliance on the amount of any draft presented under
         such Letter of Credit, whether the amount due to the beneficiary
         thereunder equals the amount of such draft, any document presented
         pursuant to such Letter of Credit proves to be in order, or any other
         statement or any other document or any signature or endorsement with
         respect thereto presented pursuant to such Letter of Credit proves to
         be forged or invalid or any statement therein proves to be inaccurate
         or untrue in any respect whatsoever, and (ii) making payment upon
         presentation of documents not complying in any immaterial respect with
         the terms of the Letter of Credit shall, in each case, not be deemed to
         constitute willful misconduct or gross negligence of the Letter of
         Credit Bank. Any action, inaction or omission on the part of the Letter
         of Credit Bank or any of its correspondents, under or in connection
         with any Letter of Credit issued by the Letter of Credit Bank or any
         renewal or extension thereof or the related instruments or documents,
         if taken in good faith and in conformity with applicable Laws and
         regulations governing Letters of Credit generally and the terms of this
         Section 0, shall be binding upon the Borrower and shall not place the
         Letter of Credit Bank or any of its correspondents under any liability
         to the Borrower. The Letter of Credit Bank's rights, powers, privileges
         and immunities specified in or arising under this Agreement are in
         addition to any heretofore or at any time hereafter otherwise created
         or arising rights, powers, privileges and immunities, whether by
         statute or rule of Law or contract.

                  (h) LETTER OF CREDIT BANK INDEMNITY. The Borrower shall
         indemnify the Letter of Credit Bank from and against: (i) any loss or
         liability (other than any caused by such Letter of Credit Bank's gross
         negligence or willful misconduct as determined by the final judgment of
         a court of competent jurisdiction) incurred by the Letter of Credit
         Bank in respect of this Agreement and the Letters of Credit and (ii)
         any out-of-pocket expenses incurred by the Letter of Credit Bank in
         defending itself or otherwise related to this Agreement or any Letter
         of Credit (other than any caused by the Letter of Credit Bank's gross
         negligence or willful misconduct as determined by the final judgment of
         a court of competent jurisdiction) including, without limitation,
         reasonable fees and expenses of legal counsel incurred by such Letter
         of Credit Bank (including, without limitation, the reasonable
         interdepartmental charges of its salaried attorneys) in the defense of
         any claim against it or in the prosecution of its rights and remedies.

                  (i) EFFECT OF APPLICABLE LAW OR CUSTOM. All Letters of Credit
         issued hereunder, all reimbursement obligations hereunder and all
         reimbursement obligations under any Reimbursement Agreement will,
         except to the extent otherwise expressly

                                       30
<PAGE>   39

         provided in this Agreement, the Reimbursement Agreements or the Letters
         of Credit, be governed by the Uniform Customs and Practice for
         Documentary Credits (1993 Revision), International Chamber of Commerce
         Publication No. 500, and any subsequent revisions thereof.

                  (j) TERMINATION OF LETTER OF CREDIT COMMITMENT. In the event
         that: (i) any restriction is imposed on the Letter of Credit Bank
         (including, without limitation, any legal lending or acceptance limits
         imposed by the United States of America or any political subdivision
         thereof or of any foreign government or central bank) which in the
         judgment of the Letter of Credit Bank would prevent the Letter of
         Credit Bank from issuing Letters of Credit or maintaining its
         commitment to issue Letters of Credit or (ii) there shall have
         occurred, at any time during the term of this Agreement: (A) any
         outbreak of hostilities or other national or international crisis or
         change in economic conditions if the effect of such outbreak, crisis or
         change would make the creation of Letters of Credit impracticable, (B)
         the enactment, publication, decree or other promulgation of any
         statute, regulation, rule or order of any court or other governmental
         authority which would materially and adversely affect the ability of
         the Borrower to perform its obligations under this Agreement, or (C)
         the taking of any action by any government or agency in respect of its
         monetary or fiscal affairs which would have a material adverse effect
         on the issuance of Letters of Credit, then the Letter of Credit Bank,
         in the case of the occurrence of any event described hereinabove, shall
         give written notice of the occurrence of such event to the Borrower and
         the Agent whereupon the commitment of the Letter of Credit Bank to
         issue Letters of Credit shall be suspended on the effective date of
         such notice and shall continue suspended until the effect of such event
         shall cease to exist.

         2.9      FEES.  The Borrower shall pay to the Agent for its own
account, or for the account of the Letter of Credit Bank or the Banks, as the
case may be, the fees set forth in this Section 0.  All fees set forth in this
Section 0 shall be paid on the date due, in immediately available funds, to the
Agent for distribution as appropriate to itself, the Letter of Credit Bank, and
the Banks and once paid, none of such fees shall be refundable under any
circumstances.

                  (a) REVOLVING CREDIT COMMITMENT FEE. The Borrower agrees to
         pay to the Agent for the benefit of the Banks, allocable to the Banks
         in accordance with the Ratable Portion of the Banks, a commitment fee
         equal to: (x) the Applicable Commitment Fee Percentage then in effect
         multiplied by (y) the average daily unused portion of the total of the
         Revolving Credit Commitments of the Banks outstanding on the Fee
         Percentage Determination Date immediately preceding the applicable Fee
         Percentage Adjustment Date. The annual fee shall be payable quarterly
         in arrears on the first day of each Fiscal Quarter commencing April 1,
         1998, until the Revolving Credit Termination Date.

                  (b) ARRANGEMENT AND STRUCTURING. The Borrower agrees to pay to
         the Agent on the Closing Date for its sole account a one time fee for
         arranging and structuring the

                                       31
<PAGE>   40

         financing transaction contemplated by this Agreement in the amount
         specified in the commitment letter executed by the Borrower and the
         Agent, dated December 9, 1997.

                  (c) ANNUAL AGENT'S FEE. The Borrower agrees to pay to the
         Agent for its sole account an annual agent fee as set forth in the
         Agent's Fee Letter.

                  (d) LETTER OF CREDIT FEES. The Borrower agrees to pay fees in
         respect of Letters of Credit issued for the account of the Borrower as
         follows:

                      (i) ANNUAL LETTER OF CREDIT RISK PARTICIPATION FEE.
                  The Borrower agrees to pay to the Agent for the benefit of the
                  Banks, allocable to the Banks in accordance with the Ratable
                  Portion of the Banks, in advance on the date of issuance of
                  each Standby Letter of Credit issued for its account and on
                  any renewal or extension date thereafter, an annual risk
                  participation fee (adjusted for Standby Letters of Credit
                  having terms less than one year) equal to: (x) the Applicable
                  Risk Participation Fee then in effect multiplied by (y) the
                  face amount of the Standby Letter of Credit issued by the
                  Letter of Credit Bank.

                      (ii) ANNUAL LETTER OF CREDIT BANK FEE.  Commencing on
                  April 1, 1998, the Borrower agrees to pay to the Agent for the
                  sole benefit of the Letter of Credit Bank, payable quarterly
                  in arrears, an issuance fee equal to: (x) one-eighth of one
                  percent (1/8%) multiplied by (y) the average daily face amount
                  of each Standby Letter of Credit outstanding during the
                  immediately preceding quarter.

                      (iii) OTHER FEES RELATING TO LETTERS OF CREDIT.  The
                  Borrower agrees to pay to the Agent for the sole benefit of
                  the Letter of Credit Bank upon issuance of any Letters of
                  Credit issued for its account any standard fees, amendment and
                  modification fees and any other standard fees and charges
                  customarily charged by the Letter of Credit Bank in connection
                  with Standby Letters of Credit.

                  (e) LATE CHARGES. If the Borrower fails to pay any amount due
         under this Agreement, or any fee in connection herewith, in full within
         ten (10) days after its due date, the Agent shall be entitled to, in
         addition to its remedies under Section 0 hereof, and the Borrower will
         incur and shall pay to the Agent for the benefit of the Banks, in each
         such case, a late charge equal to one percent (1%) of the amount failed
         to be paid. The payment of a late charge will not cure or constitute a
         waiver of any Potential Default or Event of Default under this
         Agreement.

                  (f) APPLICABLE RISK PARTICIPATION PERCENTAGE AND APPLICABLE
         FACILITY FEE PERCENTAGE. The Applicable Risk Participation Percentage
         or Applicable Commitment Fee Percentage, as the case may be, shall be
         calculated as herein specified as of the Closing Date and as of the
         first day of the calendar quarter (each an "Fee Adjustment Date")
         commencing after the date the Agent shall have received (A) financial
         statements

                                       32
<PAGE>   41

         required by Sections 0, 0 or 0, as the case may be, for the period
         ending as of the last day of the Fiscal Quarter or Fiscal Year
         immediately preceding such Fee Adjustment Date (each a "Fee
         Determination Date") and (B) a certificate complying with Section 0
         certifying the Borrower's Consolidated Total Funded Debt to EBITDA
         Ratio as of any such Fee Determination Date. On each Fee Adjustment
         Date, the Applicable Risk Participation Percentage or Applicable
         Commitment Fee Percentage, as the case may be, shall be the percentage
         set forth in the definition of "Applicable Risk Participation
         Percentage" and "Applicable Facility Fee Percentage" which corresponds
         to the Borrower's Consolidated Total Funded Debt to EBITDA Ratio as of
         the Fee Determination Date applicable to such Fee Adjustment Date. The
         Applicable Risk Participation Percentage and Applicable Commitment Fee
         Percentage effective as of a particular Fee Adjustment Date shall
         remain effective only until the next succeeding Fee Adjustment Date at
         which time the Applicable Risk Participation Percentage and Applicable
         Commitment Fee Margin shall be recalculated pursuant to this Section 0;
         except, however, that, if an Event of Default shall have occurred which
         has not been waived in writing by all of the Banks, or if the Borrower
         shall not have delivered as of such Margin Adjustment Date the
         financial statements in accordance with Sections 0, 0 and 0 of this
         Agreement, the Applicable Risk Participation Fee Percentage shall be
         eight-tenths of one percent (.80%) per annum and the Applicable
         Commitment Fee Percentage shall be three-tenths of one percent (.30%)
         per annum.

                  (g) PAYMENT OF FEES; NONREFUNDABLE. All fees set forth in this
         Section 0 shall be paid on the date due, in immediately available
         funds, to the Agent for distribution, if and as appropriate, to the
         Banks or the Letter of Credit Bank. Once paid, to the extent permitted
         by applicable Law, none of such fees shall be refundable under any
         circumstances.

         2.10     INTEREST ON REVOLVING CREDIT LOANS.

                  (a) INTEREST RATE. The Borrower shall pay interest on the
         unpaid principal amount of each Revolving Credit Loan made by each Bank
         from the date of such Revolving Credit Loan until such principal amount
         shall be paid in full as follows:

                      (i) ALTERNATE BASE RATE LOANS. During such periods as
                  any Alternate Base Rate Loan comprising a Revolving Credit
                  Borrowing is outstanding, the Borrower shall pay interest on
                  such Alternate Base Rate Loan at a rate per annum equal at all
                  times to the sum of the Alternate Base Rate, payable
                  quarterly, in arrears, on the first day of each calendar
                  quarter and on the date such Alternate Base Rate Loan
                  comprising a Revolving Credit Borrowing shall be converted or
                  paid in full (whether at maturity, by reason of acceleration
                  or otherwise) and, after maturity, on demand.

                      (ii) LIBOR RATE LOANS. During such periods as any
                  LIBOR Rate Loan comprising a Revolving Credit Borrowing is
                  outstanding, the Borrower shall pay interest on such LIBOR
                  Rate Loan at a rate per annum equal to the sum of the London
                  Interbank Offered Rate plus the Applicable LIBOR Margin in
                  effect as of the most recently preceding Margin Adjustment
                  Date occurring prior to the date of the making of such LIBOR
                  Rate Loan, or the conversion or continuation of such LIBOR
                  Rate Loan in accordance with Section 0, payable: (A) on the
                  last day of each Interest Period and (B) if such Interest
                  Period has a duration of more than three months, three months
                  after the first day of such Interest Period and (C) on the
                  date such LIBOR Rate Loan comprising a Revolving Credit
                  Borrowing shall be converted to an Alternate Base Rate Loan or
                  paid in full (whether at maturity, by reason of acceleration
                  or otherwise) and (D) after maturity, on demand.

                  (b) APPLICABLE LIBOR MARGIN; TERMS OF ADJUSTMENT.

                      (i) COMMENCEMENT; CONDITIONS. So long as no Event of
                  Default shall have occurred which has not been waived in
                  writing by all of the Banks, the Applicable LIBOR Margin shall
                  be calculated as herein specified as of the Closing Date and
                  effective as of the first day of the Fiscal Quarter (each an
                  "Margin Adjustment Date") during which the Agent shall have
                  received (A) financial statements required by Sections 0, 0 or
                  0, as the case may be, for the period ending as of the last
                  day of the Fiscal Quarter or Fiscal Year immediately preceding
                  such Margin Adjustment Date (each a "Determination Date") and
                  (B) a certificate complying with Section 0 certifying the
                  Borrower's Consolidated Funded Debt to EBITDA Ratio as of any
                  such Determination Date.

                       (ii) CALCULATION AND DURATION OF ADJUSTMENT. On each
                  Margin Adjustment Date, the Applicable LIBOR Margin shall be
                  the Applicable LIBOR Margin set forth in the definition of
                  "Applicable LIBOR Margin" which corresponds to the Borrower's
                  Consolidated Total Funded Debt to EBITDA Ratio as of the
                  Determination Date applicable to such Margin Adjustment Date.
                  The Applicable LIBOR Margin effective as of a particular
                  Margin Adjustment Date shall remain effective only until the
                  next succeeding Margin Adjustment Date at which time the
                  Applicable LIBOR Margin shall be recalculated pursuant to this
                  Subsection (b); provided, however, that: (I) if at any time an
                  Event of Default shall have occurred that has not been waived
                  in writing by all of the Banks, or if the Borrower shall not
                  have delivered as of any Margin Adjustment Date the financial
                  statements required to have been delivered under Sections 0
                  and 0 of this Agreement, then, at the election of the Required
                  Banks, the Applicable LIBOR shall immediately adjust to be
                  eight-tenths of one percent (0.80%) per annum and (II) if an
                  Event of Default shall have occurred which has not been waived
                  in writing by the Required Banks, the interest rate shall,
                  upon the request

                                       34
<PAGE>   43

                  of the Required Banks, be the interest rate applicable
                  pursuant to Section 0 of this Agreement.

                  (c) DEFAULT INTEREST. Following the occurrence of an Event of
         Default which has not been waived in writing by all of the Banks, (i)
         the principal thereof and the unpaid interest and fees thereon shall,
         upon the request of the Required Banks, bear interest, payable on
         demand, for Alternate Base Rate Loans and LIBOR Rate Loans, at a rate
         per annum which shall be equal at all times to two percent (2.0%) in
         excess of the Alternate Base Rate and (ii) the Applicable Risk
         Participation Fee shall be two percent (2%) per annum.

                  (d) INTEREST RATE DETERMINATION.

                      (i) AGENT DETERMINATION; NOTICE.  The Agent shall
                  determine the London Interbank Offered Rate in accordance
                  with the definition of London Interbank Offered Rate set forth
                  in Section 0 of this Agreement.  The Agent shall give prompt
                  notice to each of the Banks and the Borrower of the applicable
                  interest rate determined by the Agent for purposes of Sections
                  0 and 0 of this Agreement.

                      (ii) FAILURE OF BORROWER TO ELECT. If no Interest Period
                  is specified in any Credit Request or any Rate
                  Conversion/Continuation Request for any LIBOR Rate Loans, the
                  Borrower shall be deemed to have selected an Interest Period
                  with a duration of one month. If the Borrower shall not have
                  given notice in accordance with Section 0 of this Agreement to
                  continue any LIBOR Rate Loans into a subsequent Interest
                  Period (and shall not have otherwise delivered a Rate
                  Conversion/Continuation Request in accordance with Section 0
                  of this Agreement to convert such Loans), such LIBOR Rate
                  Loans shall, at the end of the Interest Period applicable
                  thereto (unless repaid pursuant to the terms hereof),
                  automatically convert into Alternate Base Rate Loans.

         2.11     PAYMENTS AND COMPUTATIONS.

                  (a) PAYMENTS; APPLICATION OF PAYMENTS. Except to the extent
         otherwise provided herein, all payments of Obligations shall be made in
         Dollars, in immediately available funds, without setoff, counterclaim,
         defense or deduction of any kind, to the Agent not later than 12:00
         noon (Cleveland, Ohio time) on the day on which such payment shall
         become due by deposit of such funds to the Agent's account maintained
         at the Payment Office of the Agent. Payments received after 12:00 noon
         (Cleveland, Ohio time) shall be deemed to have been received on the
         next succeeding Business Day. The Borrower shall at the time of making
         a payment hereunder specify to the Agent the Obligations to which such
         payment is to be applied. If the Borrower does not specify an
         application or if an Event of Default has occurred which has not been
         waived in writing by the Required Banks, the Agent may, subject to
         Section 0 of this Agreement, distribute a payment to the Letter of
         Credit Bank or the Banks for application to such Obligations as the
         Agent, in its sole discretion, elects or as the Required Banks shall
         have directed; provided, however, the Agent will use reasonable efforts
         to avoid an application of a payment which causes early prepayment of a
         LIBOR Rate Borrowing prior to expiration of its applicable Interest
         Period. Each payment received by the Agent for the account of the
         Letter of Credit Bank or a Bank shall be paid on the day of such
         receipt, in immediately available funds, to the Letter of Credit Bank
         or Bank for the account of its respective Lending Office.

                  (b) PAYMENT PROCEDURES. The Control Account of the Borrower
         will be charged with all Advances made by the Banks to the Borrower and
         all other Obligations of the Borrower under this Agreement or any other
         Loan Document. The Borrower hereby authorizes each Bank to charge the
         Loan Account of the Borrower with such Obligations. The Control Account
         of the Borrower will be credited in accordance with this Section 0 with
         all payments received by the Agent directly from such Borrower or for
         the account of the Borrower. The Agent shall send the Borrower
         statements in accordance with the Bank's standard procedures. Absent
         manifest error, each such statement shall be final, conclusive and
         binding on the Borrower. The Loan Accounts of each Bank shall reflect
         the activity in the Control Account applicable to such Bank's Loan
         Account.

                  (c) AUTHORIZATION TO CHARGE ACCOUNT. If and to the extent
         payment owed to the Agent or any Bank is not made when due hereunder or
         under the Revolving Credit Notes, the Borrower hereby authorizes the
         Agent and each Bank to charge from time to time against any or all of
         the Borrower's accounts with the Agent or such Bank, as the case may
         be, any amount so due. Notice of any such charge shall be given
         promptly to the Borrower by the Agent or such Bank, as the case may be.

                  (d) COMPUTATIONS OF INTEREST AND FEES. All computations of
         interest on LIBOR Rate Loans, as well as fees and other compensation
         hereunder, shall be made by

                                       36
<PAGE>   45

         the Agent on the basis of a year of 360 days and for the actual number
         of days (including the first day but excluding the last day) occurring
         in the period for which such interest or fees are payable. All
         computations of interest on Alternate Base Rate Loans shall be made by
         the Agent on the basis of a year of 365 or 366 days and in each case
         for the actual number of days (including the first day but excluding
         the last day) occurring in the period for which such interest or fees
         are payable. Each determination by the Agent of interest, fees or other
         amounts of compensation due hereunder shall be, absent manifest error,
         prima facie evidence thereof.

                  (e) PAYMENT NOT ON BUSINESS DAY. Whenever any payment
         hereunder or under the Revolving Credit Notes shall be stated to be due
         on a day other than a Business Day, such payment shall be made on the
         next succeeding Business Day. Any such extension of time shall in such
         case be included in the computation of payment of interest, fees or
         other compensation, as the case may be.

                  (f) PRESUMPTION OF PAYMENT IN FULL BY BORROWER. Unless the
         Agent shall have received notice from the Borrower prior to the date on
         which any payment is due to the Banks hereunder that the Borrower will
         not make such payment in full, the Agent may assume that the Borrower
         has made such payment in full to the Agent on such date. In reliance
         upon such assumption, the Agent may, but shall not be obligated to,
         distribute to each Bank on such due date the amount then due such Bank.
         If and to the extent the Borrower shall not have made such payment in
         full to the Agent, each Bank shall repay to the Agent promptly upon
         demand the amount distributed to such Bank together with interest
         thereon, for each day from the date such amount is distributed to such
         Bank until the date such Bank repays such amount to the Agent, at the
         Federal Funds Rate for the first three (3) days from and after such
         date and thereafter at the Interest Rate then applicable to Alternate
         Base Rate Loans.

         2.12     CHANGE IN LAW; LIBOR RATE LOANS UNLAWFUL. Notwithstanding any
other provision of this Agreement, if any Bank determines that any applicable
Law, or any change therein, or any change in the interpretation or
administration of any Law by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by such Bank (or its Lending Office) with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency, shall make it unlawful or impossible, or any such
governmental authority, central bank or agency asserts that it is unlawful, for
any Bank or its Lending Office to perform its obligations hereunder to make
LIBOR Rate Loans or to fund or maintain LIBOR Rate Loans hereunder, then, upon
notice to the Agent and the Borrower by such Bank: (a) the obligation of all of
the Banks to make, or to convert Loans into, LIBOR Rate Loans shall be suspended
until the Agent shall notify the Borrower and the Banks that the circumstances
causing such suspension no longer exist and (b) the Borrower shall immediately,
or at such later date, if any, as may thereafter be permitted by relevant Law,
prepay in full the then outstanding principal amount of all LIBOR Rate Loans of
all Banks, together with interest accrued thereon and any other amounts

                                       37
<PAGE>   46

payable to the Banks hereunder unless the Borrower, upon notice from the Agent,
converts all LIBOR Rate Loans of all Banks then outstanding into Loans of
another Type in accordance with Section 0 of this Agreement as to which such
circumstances do not exist. Any such payment or Rate Conversion shall be subject
to the provisions of Section 0 of this Agreement.

         2.13     UNAVAILABILITY.  Notwithstanding any other provision in this
Agreement, if at any time with respect to any LIBOR Rate Loans:

                  (a) INADEQUATE RATE. Any Bank notifies the Agent that the
         London Interbank Offered Rate for any Interest Period for such LIBOR
         Rate Loans will not adequately reflect the cost to such Bank of making,
         funding or maintaining its LIBOR Rate Loans for such Interest Period,
         the Agent shall promptly notify the Borrower and the Banks;

                  (b) UNAVAILABLE QUOTATIONS. The Agent determines (which
         determination shall be conclusive) that quotations of interest rates
         for Dollar deposits are not being provided in the relevant amounts or
         for the relevant maturities to, or the circumstances affecting the
         London interbank market of deposits in Dollars make it impracticable
         to, determine the London Interbank Offered Rate, or

                  (c) UNAVAILABLE DEPOSITS. Any Bank determines that Dollar
         deposits of the relevant amount for the relevant Interest Period are
         not available in the London interbank market of deposits of Dollars for
         the purpose of funding the LIBOR Rate Loans,

then: (i) each LIBOR Rate Loan will automatically, on the last day of the then
existing Interest Period therefor, convert into an Alternate Base Rate Loan and
(ii) the obligation of the Banks to make or to convert Loans into LIBOR Rate
Loans or continue LIBOR Rate Loans shall be suspended until the Agent shall
notify the Borrower and the Banks that the circumstances causing such suspension
no longer exist.

         2.14     PRO RATA TREATMENT. Except as set forth in Sections 0, 0 and 0
of this Agreement, each Borrowing, each payment or prepayment of principal of
any Borrowing, each payment of interest on the Loans, each payment of the fees
provided for hereunder, each Rate Conversion or Rate Continuation of Loans
comprising a Borrowing shall be allocated among the Banks in accordance with
each Bank's Ratable Portion (or if the Commitments shall have expired or been
terminated, in accordance with the respective principal amounts of each Bank's
Loans).

3        CONDITIONS OF LENDING.

         3.1      CONDITIONS PRECEDENT TO INITIAL LOANS.  The effectiveness of
this Agreement, the obligation of each Bank to make a Revolving Credit Loan on
the occasion of each Revolving Credit Borrowing and each Rate Conversion or Rate
Continuation, and the obligation of the Letter of Credit Bank to issue any
Letter of Credit are subject to the condition precedent that the Agent shall
have received on or before the Closing Date the following:

         assessment, charge or levy need be paid so long as and to the extent
         that it is contested in good faith and by timely and appropriate
         proceedings effective to stay, during the pendency of such proceedings,
         the enforcement thereof and the creation of any Lien, and appropriate

         Borrower's and its Subsidiaries' financial condition, each of which
         parties is hereby authorized by the Borrower to make such information
         available to such Bank to the same extent that it would to the Borrower
         subject only to such professional and legal restrictions to which such
         parties may be bound and which cannot be waived by the Borrower or its
         Subsidiaries.

and the Banks may be entitled, all of which rights and remedies shall be

this Agreement shall occur which has not been waived in writing by the Required
Banks, each Bank shall have the right (in addition to such other rights as it

Agreement) at any time to set off against and to appropriate and apply toward
the payment of the Obligations and all other Indebtedness then owing to it (and

whether or not the same shall then have matured, any and all deposit balances
then owing by that Bank to or for the credit or account of the Borrower, all
without notice to or demand upon the Borrower or any other Person, all such
notices and demands being hereby expressly waived.

         7.5      ACTIONS IN RESPECT OF THE LETTERS OF CREDIT UPON DEFAULT. Upon
the occurrence of Event of Default (unless waived in writing by the Banks in
accordance with this Agreement), to the extent that any Letters of Credit have

Credit, to be maintained at such office of the Agent as Agent shall direct, an
amount equal to the maximum amount available to be drawn under the Letters of
Credit. In the event that Borrower shall not deposit such funds upon demand by
the Agent, the Agent may, in its sole discretion, deposit any other funds of
Borrower in the possession of the Agent, to the Letter of Credit Collateral
Account until the amount deposited in such account equals the maximum amount
available to be drawn under the Letters of Credit. The Letter of Credit
Collateral Account shall be in the name of Agent (as a cash collateral account),
but under the sole dominion and control of the Agent and subject to the terms of
this Agreement.

         7.6      LETTER OF CREDIT COLLATERAL ACCOUNT.

                  (a) APPLICATION. The Agent may, at any time or from time to
         time after

                                       60
<PAGE>   69

         funds are deposited in the Letter of Credit Collateral Account, apply
         funds then held in the Letter of Credit Collateral Account to the
         payment of any amounts, in such order as the Agent may elect or shall
         be directed by the Banks, as shall have become or shall become due and
         payable by the Borrower to the Letter of Credit Bank under this
         Agreement or any Reimbursement Agreement first, in respect of the
         Letters of Credit and second, after the occurrence and during the
         continuance of any Event of Default, in respect of all other amounts
         constituting Obligations.

                  (b) NO BORROWER OR THIRD PARTY CLAIMS. Neither the Borrower
         nor any Person claiming on behalf of or through Borrower shall have any
         right to withdraw any of the funds held in the Letter of Credit
         Collateral Account.

                  (c) NO LIENS OR TRANSFERS OF ACCOUNT. The Borrower agrees that
         it will not: (i) sell or otherwise dispose of any interest in the
         Letter of Credit Collateral Account or any funds held therein, or (ii)

         contemplated by this Agreement.

         in the custody and preservation of any funds held in the Letter of
         Credit Collateral Account and shall be deemed to have exercised such
         care if such funds are accorded treatment substantially equivalent to
         that which the Agent accords its own property, it being understood that

         steps to preserve rights against any parties with respect to any such
         funds.

         7.7      TERMINATION; EFFECT ON BORROWER OBLIGATIONS. Any termination
by the Agent and\or any Bank of its performance pursuant to this Section 0 shall
not absolve, release, or otherwise affect the liability of the Borrower in
respect of transactions prior to such termination or affect any of the Liens,
rights, powers, and remedies of the Agent or such Bank, which such Liens,
rights, powers and remedies shall, in all events, continue until all Obligations
of the Borrower to the Agent and the Banks are satisfied.

         7.8      EQUALIZATION. Each Bank agrees with the other Banks that if at
any time it shall obtain any Advantage over the other Banks or any thereof in
respect of the Loans it will purchase from such other Bank or Banks, for cash
and at par, such additional participation in the Loans owing to the other or
others as shall be necessary to nullify the Advantage. If any such Advantage
resulting in the purchase of an additional participation as aforesaid shall be
recovered in whole or in part from the Bank receiving the Advantage, each such
purchase shall be rescinded, and the purchase price restored (with interest and
other charges if and to the extent actually incurred by the Bank receiving the
Advantage) ratably to the extent of the recovery. During the existence of any
Potential Default, any payment (whether made voluntarily or involuntarily, by
offset of any deposit or other indebtedness or otherwise) of any Indebtedness
owing by the Borrower to any Bank shall be applied to the Obligations owing to
that Bank until the same shall have been paid in full before any thereof shall
be applied to other Indebtedness owing to that Bank.

         7.9      REMEDIES CUMULATIVE. The above-stated remedies are not
intended to be exhaustive and the full or partial exercise of any of such
remedies shall not preclude the full or partial exercise of any other remedy by
the Agent under this Agreement, under any Loan Document, or at equity or under
at law.

8        THE AGENT.

         8.1      THE AGENT. Each Bank irrevocably appoints the Agent to act as
agent under this Agreement and the Loan Documents for the benefit of such Bank,
with full authority to take such actions, and to exercise such powers, on behalf
of the Banks in respect of this Agreement and the Loan Documents as are herein
and therein respectively delegated to the Agent or as are reasonably incidental
to those delegated powers.  The Agent in such capacity shall be deemed to be an
independent contractor of the Banks.

         8.2      NATURE OF APPOINTMENT. The Agent shall have no fiduciary
relationship with any Bank by reason of this Agreement and the Loan Documents.
The Agent shall not have any duty or responsibility whatsoever to any Bank
except those expressly set forth in this Agreement and the Loan Documents.
Without limiting the generality of the foregoing, each Bank acknowledges that
the Agent is acting as such solely as a convenience to the Banks and not as a
manager of the commitments or the Obligations evidenced by the Revolving Credit
Notes. This Section 0 does not confer any rights upon the Borrower or anyone
else (except the Banks), whether as a third party beneficiary or otherwise.

banking, financial, trust, advisory or other business with the Borrower
(including, without limitation, the acceptance of deposits, the extension of
credit and the acceptance of fiduciary appointments) without notice to the
Banks, without accounting to the Banks, and without prejudice to the Agent's
rights as a Bank under this Agreement and the Loan Documents except as may be

exercise any discretion or take any action as to matters not expressly provided
for by this Agreement and the Loan Documents (including, without limitation,
collection and enforcement actions in respect of any Obligations under the
Revolving Credit Notes or this Agreement and any collateral therefor), except
that the Agent shall take such action, or omit to take such action (other than
actions referred to in Section 0 of this Agreement), as may be reasonably
requested, with instructions in writing, by the Required Banks or all of the
Banks, as applicable pursuant to Section 0 of this Agreement and which actions
and omissions shall be binding upon all of the Banks; provided, however, that
the Agent shall not be required to act (or omit any act) if, in its judgment,
any such action or omission might expose the Agent to personal liability or
might be contrary to this Agreement, any Loan Document or any applicable Law.

         8.5      BANK'S DILIGENCE. Each Bank: (a) represents and warrants that
it has made its own decision to enter into this Agreement and the Loan Documents
and (b) agrees that it will make its own decision as to taking or not taking
future actions in respect of this Agreement and the Loan Documents; in each case
without reliance on the Agent or any other Bank and on the basis of its
independent credit analysis and its independent examination of and inquiry into
such documents and other matters as it deems relevant and material.

         8.6      NO IMPLIED REPRESENTATIONS. The Agent shall not be liable for
any representation, warranty, agreement or obligation of any kind of any other

in this Agreement or any Loan Document or by a Bank in any notice or other
communication or by anyone else or otherwise.

         8.7      SUB-AGENTS. The Agent may employ agents and shall not be

keep itself informed as to any Person's compliance with any provision of this
Agreement or any Loan Document, (b) to make any inquiry into the properties,
financial condition or operation of the Borrower or any other matter relating to
this Agreement or any Loan Document, (c) to report to any Bank any information
(other than which this Agreement or any Loan Document expressly requires to be
so


                                       63
<PAGE>   72

reported) that the Agent or any of its Affiliates may have or acquire in respect
of the properties, business or financial condition of the Borrower or any other
matter relating to this Agreement or any Loan Document or (d) to inquire into
the validity, effectiveness or genuineness of this Agreement or any Loan
Document.

         8.9      NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge of any Potential Default or Event of Default unless and until it shall
have received a written notice from the Borrower or any Bank describing it and
citing the relevant provision of this Agreement or any Loan Document. The Agent
shall give each Bank prompt notice of any such written notice other than the
Bank that shall have given the written notice of the Event of Default.

         8.10     AGENT'S LIABILITY. Neither the Agent nor any of its directors,
officers, employees, attorneys, and other agents shall be liable for any action
or omission on their respective parts except for gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the Agent:
(a) may treat the payee of any Revolving Credit Note as the holder thereof until
the Agent receives a fully executed copy of the Assignment Agreement required by
Section 0 of this Agreement signed by such payee and in form satisfactory to the
Agent and the fee required by Section 0 of this Agreement; (b) may consult with
legal counsel, independent public accountants and other experts selected by it
and shall not be liable for any action taken or omitted to be taken in good
faith by it in accordance with the advice or such counsel, accountants or
experts which have been selected by the Agent with reasonable care; (c) makes no
warranty or representation to any Bank and shall not be responsible to any Bank

this Agreement or any other Loan Document, including, without limitation, the
truth of the statements made in any certificate delivered by the Borrower under
Sections 0 or 0 of this Agreement or in any Credit Request, Rate
Continuation/Conversion Request or any other similar notice or delivery, the
Agent being entitled for the purposes of determining fulfillment of the
conditions set forth therein to rely conclusively upon such certificates; (d)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement, the
Revolving Credit Notes or any other Loan Document or to inspect the property
(including the books and records) of the Borrower; (e) shall not be responsible
to any Bank for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement, or collateral covered by

or in respect of this Agreement, the Revolving Credit Notes or any other Loan
Document by acting upon any notice, consent, certificate or other instrument or
writing (which may be by telegram, telecopy, cable or telex) believed by it in
good faith to be genuine and correct and signed or sent by the proper party or
parties.

         Neither the Agent nor any of its directors, officers, employees or
agents shall have any responsibility to the Borrower on account of the failure
of or delay in performance or breach by any Bank of any of its obligations
hereunder or to any Bank on account of the failure of or delay in performance or
breach by any other Bank or the Borrower of any of their respective obligations
hereunder or under any Loan Document or in connection herewith or therewith. The

Banks each hereby acknowledge that the Agent shall be under no duty to take any
discretionary action permitted to be taken by it pursuant to the provisions of
this Agreement, the Revolving Credit Notes or any other Loan Document unless it
shall be requested in writing to do so by the Required Banks or all of the
Banks, as applicable pursuant to Section 0 of this Agreement.

         8.11     AGENT'S INDEMNITY. The Banks shall indemnify the Agent, in its
capacity as Agent (to the extent the Agent is not reimbursed by the Borrower)
from and against: (a) any loss or liability (other than any caused by the
Agent's gross negligence or willful misconduct) incurred by the Agent acting in
the capacity as Agent in respect of this Agreement, the Revolving Credit Notes
or any Loan Document and (b) any out-of-pocket costs and expenses incurred in
defending itself or otherwise related to this Agreement, the Revolving Credit
Notes or any Loan Document (other than any caused by the Agent's gross
negligence or willful misconduct) including, without limitation, reasonable fees
and disbursements of legal counsel of its own selection (including, without
limitation, the reasonable interdepartmental charges of its salaried attorneys)

arising in connection with its actions in its capacity as Agent); provided,
however, that each Bank shall be liable for only its Ratable Portion of the

Section 0 of this Agreement, the provisions of this Section 0 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement.

         8.12     RESIGNATION OF AGENT. The Agent may resign as Agent effective
ten (10) Business Days after giving notice thereof to the Banks for any reason.
If the Agent shall resign as Agent under this Agreement, the Required Banks
shall appoint from among the Banks (other than the Bank that has resigned) a
successor agent for the Banks, which successor agent shall be reasonably
acceptable to the Borrower. In the case of resignation by the Agent, if no
successor agent shall have been appointed by the time such resignation becomes
effective, then the retiring Agent may, on behalf of the Banks, appoint a
successor agent from among the remaining Banks. Upon appointment (whether
effected by the Required Banks or the retiring Agent on behalf of the Banks),
the successor agent shall succeed to the rights, powers and duties of the Agent,
and the term "Agent" shall mean such successor agent, effective upon its
appointment, and the former Agent's rights, powers and duties as Agent shall be
terminated, without any other or further act or deed on the part of such former
Agent or any of the parties to this Agreement or any holder of the Revolving
Credit Notes.

9        TRANSFERS AND ASSIGNMENTS.

         9.1      TRANSFER OF COMMITMENTS.  Each Bank shall have the right at
any time or times to transfer to another financial institution, without
recourse, all or any part of: such Bank's Revolving Credit Commitment; any Loan
made by such Bank; any Revolving Credit Note executed in favor of such Bank, and
any participations, if any, purchased by the Bank pursuant to Section 0 of this
Agreement; provided, however, in each such case, that the transferor and the
transferee shall have complied with the following requirements:

                  (a) PRIOR CONSENT. No transfer (other than a transfer by any
         Bank to any Affiliate of such Bank) may be consummated pursuant to this
         Section 0 in the minimum amount of Five Million Dollars ($5,000,000)
         without the prior written consent of the Borrower and the Agent, which
         shall not be unreasonably withheld; provided, however, that, (i) the
         consent of the Borrower shall not be required in the event a Bank
         transfers it's commitment to another Bank and (ii) no Bank shall make
         any transfer pursuant to this Section 0 if after giving effect to such
         transfer such Bank's Revolving Credit Commitment would be less than
         Five Million Dollars ($5,000,000) unless such Bank shall transfer all
         if its Revolving Credit Commitment and ceases to be a "Bank" under this
         Agreement; provided, further, that, if at the time of the proposed
         transfer the Borrower is the subject of a proceeding referenced in
         Sections 0 or 0 of this Agreement or an Event of Default has otherwise
         occurred which has not been waived by the Required Banks, the
         Borrower's consent shall not be required and any Bank may consummate a
         transfer contemplated by this Section 0 with the consent of the Agent.
         Notwithstanding anything to the contrary, any Bank may at any time (i)
         assign all or any portion of its rights under this Agreement and its
         Revolving Credit Notes to the Federal Deposit Insurance Corporation or
         other similar governmental agency, or (ii) create a security interest
         in all or any portion of such rights in favor of any Federal Reserve
         Bank, in each case in accordance with Regulation A or the Board of
         Governors of the Federal Reserve System,

                                       66
<PAGE>   75

         and no such assignment or creation shall release such assigning Bank
         from its obligations hereunder.

                  (b) AGREEMENT; TRANSFER FEE. The transferor: (i) shall remit
         to the Agent an administrative fee of Three Thousand Dollars ($3,000)
         and (ii) shall cause the transferee to execute and deliver to the
         Borrower, the Agent and each Bank (A) an Assignment Agreement,
         substantially in the form of Exhibit F attached hereto, and otherwise
         in form and substance satisfactory to the Agent and its counsel (a
         "Bank Assignment Agreement"), together with the consents and releases
         referenced therein and (B) such additional amendments, assurances and
         other writings as the Agent may reasonably require to effect such
         transfer.

                  (c) REVOLVING CREDIT NOTES. The Borrower shall execute and
         deliver to the Agent, the transferor and the transferee, any consent or
         release (of all or a portion of the obligations of the transferor) to
         be delivered in connection with the Assignment Agreement. If a Bank's
         entire interest in its Revolving Credit Commitment and in all of its
         Loans have been transferred, the Borrower shall execute and deliver to
         the transferee appropriate Revolving Credit Notes against return of the
         Revolving Credit Notes (marked "replaced") held by the transferor. If
         only a portion of a Bank's interest in its Revolving Credit Commitment
         and Loans has been transferred, the Borrower shall execute and deliver
         a new Revolving Credit Note to each of the transferor and the
         transferee against return of the original such Revolving Credit Notes
         of the transferor (marked "replaced") held by the transferor.

                  (d) PARTIES. Upon satisfaction of the requirements of this
         Section 0, including the payment of the fee and the delivery of the
         documents set forth in Section 0 above, (i) the transferee shall become
         and thereafter be deemed to be a "Bank" for the purposes of this
         Agreement and (ii) the transferor (A) shall continue to be a "Bank" for
         the purposes of this Agreement only if and to the extent that the
         transfer shall not have been a transfer of its entire interest in its
         Revolving Credit Commitment and Loans and (B) shall cease to be and
         thereafter shall no longer be deemed to be a "Bank" in the case of any
         transfer of its entire interest in its Revolving Credit Commitment and
         Loans and (iii) the signature pages hereto and Annex A hereto shall be
         automatically amended, without further action, to reflect the result of
         any such transfer.

         9.2      SALE OF PARTICIPATIONS. Each Bank shall have the right at any
time or times to sell one or more participations or subparticipations to a
financial institution in all or any part of: such Bank's Revolving Credit
Commitment; any Loan made by such Bank; any Revolving Credit Note executed in
favor of such Bank, and any participations, if any, purchased by such Bank
pursuant to Section 0 of this Agreement or this Section 0; provided, however, in
each such case, that the transferor and the transferee shall have complied with
the following requirements:

                  (a) BENEFITS OF PARTICIPANT. The provisions of Section 0 of
         this Agreement

                                       67
<PAGE>   76

         shall inure to the benefit of each purchaser of a participation or
         subparticipation (provided that each such participant shall look solely
         to the seller of its participation for those benefits and the
         Borrower's liabilities, if any, under any of those sections shall not
         be increased as a result of the sale of any such participation) and
         Agent shall continue to distribute payments pursuant to this Agreement
         as if no participation has been sold.

                  (b) RIGHTS RESERVED. In the event any Bank shall sell any
         participation or subparticipation, that Bank shall, as between itself
         and the purchaser, retain all of its rights (including, without
         limitation, rights to enforce against the Borrower this Agreement and
         the Loan Documents) and duties pursuant to this Agreement and the Loan
         Documents, including, without limitation, that Bank's right to approve
         any waiver, consent or amendment pursuant to Section 0 of this
         Agreement, except if and to the extent that any such waiver, consent or
         amendment would (A) reduce any fee or commission allocated to the
         participation or subparticipation, as the case may be, (B) reduce the
         amount of any principal payment on any Loan allocated to the
         participation or subparticipation, as the case may be, or reduce the
         principal amount of any Loan so allocated or the rate of interest
         payable thereon, or (C) extend the time for payment of any amount
         allocated to the participation or subparticipation, as the case may be.

                  (c) NO DELEGATION. No participation or subparticipation shall
         operate as a delegation of any duty of the seller thereof. Under no
         circumstance shall any participation or subparticipation be deemed a
         novation in respect of all or any part of the seller's obligations
         pursuant to this Agreement.

         9.3      CONFIDENTIALITY. The Agent, the Letter of Credit Bank and each
Bank hereby agrees to use commercially reasonable efforts to keep, and to cause
its agents, attorneys and financial advisors to keep, any information delivered
or made available by the Borrower or any of its Subsidiaries to it confidential
from anyone other than Persons employed or retained by the Agent, the Letter of
Credit Bank or any Bank who are or are expected to become engaged in evaluating,
approving, structuring or administering the Loans; provided that nothing herein
shall prevent the Agent, the Letter of Credit Bank or any Bank from disclosing
such information (a) to any other Bank, (b) to any other person if reasonably
incidental to the administration of the Loans, (c) upon the order of any court
or administrative agency, (d) upon the request or demand of any regulatory
agency or authority, (e) which has been publicly disclosed other than as a
result of a disclosure by the Agent, the Letter of Credit Bank or any other Bank
which is not permitted by this Agreement, (f) in connection with any litigation
to which the Agent, the Letter of Credit or any Bank, or their respective
Affiliates may be a party, (g) to the extent reasonably required in connection
with the exercise of any remedy hereunder, (h) to the Agent's, the Letter of
Credit Bank or such Bank's legal counsel and independent auditors, (i) to any
actual or proposed participant or assignee of all or part of its rights
hereunder so long as such participant or assignee has agreed in writing to be
bound by the terms of this Section 0 and (j) to the extent required by Law.

10       INDEMNITIES.

         10.1     INCREASED COSTS. If, due to either: (a) the introduction of
any Law or regulation, or any change (other than any change by way of imposition
or increase of reserve requirements in respect of LIBOR Rate Loans otherwise
included in the Eurocurrency Reserve Percentage) in or in the interpretation of
any Law or regulation or (b) the compliance with any guideline or request from
any central bank or other governmental authority (whether or not having the
force of Law), there shall be any increase in the cost to any Bank of agreeing
to make or making, funding or maintaining Loans, then the Borrower shall from
time to time, upon demand by such Bank (with a copy of such demand to the
Agent), pay to the Agent for the account of such Bank additional amounts
sufficient to indemnify such Bank for such increased cost.

         10.2     RISK-BASED CAPITAL. If any Bank determines that: (a)
compliance with any Law or regulation or any interpretation or administration
thereof by any governmental authority charged with the interpretation or
administration thereof or (b) compliance with any directive, guideline or
request from any central bank or other governmental authority (whether or not
having the force of Law) affects or would affect the amount of capital required
or expected to be maintained by such Bank or any corporation controlling such
Bank and that the amount of such capital required to be so maintained is
increased by or based upon the existence of such Bank's Revolving Credit
Commitment to lend hereunder and other commitments of this type, then, upon
demand by such Bank (with a copy of such demand to the Agent), the Borrower
shall immediately pay to the Agent for the account of such Bank, from time to
time as specified by such Bank, additional amounts sufficient to indemnify such
Bank or such corporation, to the extent that such Bank reasonably determines
such increase in capital to be allocable to the existence of such Bank's
Revolving Credit Commitment to lend hereunder.

         10.3     TAXES.

                  (a) TAXES; WITHHOLDING. Any and all payments by the Borrower
         hereunder, under the Revolving Credit Notes or the other Loan Documents
         shall be made, in accordance with the provisions of Section 2, free and
         clear of and without deduction for any and all present or future taxes,
         levies, imposts, deductions, charges or withholdings, and all
         liabilities with respect thereto, excluding, in the case of each Bank,
         the Letter of Credit Bank and the Agent, taxes imposed on its income,
         and franchise taxes imposed on it, by the jurisdiction under the Laws
         of which such Bank, the Letter of Credit Bank or the Agent, as the case
         may be, is organized or any political subdivision thereof and, in the
         case of each Bank, taxes imposed on its income, and franchise taxes
         imposed on it, by the jurisdiction of such Bank's Lending Office or any
         political subdivision thereof (all such non-excluded taxes, levies,
         imposts, deductions, charges, withholdings and liabilities being
         hereinafter referred to as "Taxes"). If the Borrower shall be required
         by Law to deduct any Taxes from or in respect of any sum payable
         hereunder or under any Revolving Credit Note to any Bank, the Letter of
         Credit Bank or the Agent and makes such deductions from the sums so
         payable: (i) the sum payable shall be increased as may



                                       69
<PAGE>   78

         be necessary so that after making all required deductions (including
         deductions applicable to additional sums payable under this Section 0)
         such Bank, the Letter of Credit Bank or the Agent receives an amount
         equal to the sum it would have received had no such deductions been
         made, (ii) the Borrower shall make such deductions and (iii) the
         Borrower shall pay the full amount deducted to the relevant taxation
         authority or other authority in accordance with applicable Law. All
         such Taxes shall be paid by the Borrower prior to the date on which
         penalties attach thereto or interest accrues thereon; provided,
         however, that, if any such penalties or interest become due, the
         Borrower shall make prompt payment thereof to the appropriate
         governmental authority.

                  (b) STAMP TAXES. The Borrower agrees to pay, and will
         indemnify each Bank, the Letter of Credit Bank or the Agent for, any
         present or future stamp or documentary taxes or any other excise or
         property taxes, charges or similar levies which arise from any payment
         made hereunder, under the Revolving Credit Notes or from the execution,
         delivery or registration of, or otherwise with respect to, this
         Agreement, the Revolving Credit Notes or the Letters of Credit
         (hereinafter referred to as "Other Taxes").

                  (c) INDEMNIFICATION FOR OTHER TAXES. The Borrower will
         indemnify each Bank, the Letter of Credit Bank and the Agent for the
         full amount of Taxes or Other Taxes (including, without limitation, any
         Taxes or Other Taxes imposed by any jurisdiction on amounts payable
         under this Section 0) paid by such Bank, the Letter of Credit Bank or
         the Agent and any liability (including penalties, interest and
         expenses) arising therefrom or with respect thereto, whether or not
         such Taxes or Other Taxes were correctly or legally asserted. Any
         indemnification payment shall be made within thirty (30) days from the
         date such Bank, the Letter of Credit Bank or the Agent (as the case may
         be) makes written demand therefor.

                  (d) REQUEST FOR REFUND. At the reasonable request of the
         Borrower, each Bank, the Letter of Credit Bank and the Agent shall
         apply at the Borrower's expense for a refund in respect of Taxes or
         Other Taxes previously paid by the Borrower pursuant to this Section 0
         if in the good faith opinion of such Bank, the Letter of Credit Bank or
         the Agent there is a reasonable basis for such refund. Notwithstanding
         the foregoing, none of the Banks, the Letter of Credit Bank or the
         Agent shall be obligated to pursue such refund if, in the exercise of
         its good faith judgment, such action would be disadvantageous to it. If
         any Bank, the letter of Credit Bank or the Agent subsequently receives
         from a taxing authority a refund of any Tax previously paid by the
         Borrower and for which the Borrower has indemnified the Bank pursuant
         to this Section 0, such Bank, the letter of Credit Bank or the Agent,
         as the case may be, shall within thirty (30) days after receipt of such
         refund, and to the extent permitted by applicable law, pay to the
         Borrower the net amount of any such recovery after deducting taxes and
         expenses attributable thereto.

                  (e) FURNISHING OF CERTIFICATE. Within thirty (30) days after
         the date of any payment of Taxes, the Borrower will furnish to the
         Agent, at its address referred to in

                                       70
<PAGE>   79

         Section 0 of this Agreement, the original or a certified copy of a
         receipt evidencing payment thereof. If Taxes ever become payable in
         respect of any payment hereunder or under the Revolving Credit Notes
         made during a Fiscal Quarter, thereafter the Borrower will furnish to
         the Agent, within thirty (30) days after the end of such Fiscal
         Quarter, at such address, a certificate from the Borrower stating that
         any payments made during such Fiscal Quarter are exempt from or not
         subject to Taxes.

                  (f) EXEMPTION CERTIFICATE. Not later than: (a) the Closing
         Date, (b) in the case of any bank or financial institution that becomes
         a Bank after the Closing Date pursuant to Section 0 of this Agreement,
         the date of the instrument of assignment pursuant to which such bank or
         financial institution became a Bank, (c) annually on each Anniversary
         Date thereafter or (d) such other times as the Agent or the Borrower
         may reasonably request: (i) each Bank organized under the laws of a
         jurisdiction outside the United States shall provide the Agent and the
         Borrower with duly completed copies of Form 1001 or Form 4224 or any
         successor form prescribed by the Internal Revenue Service of the United
         States certifying that such Bank is exempt from United States
         withholding taxes with respect to all payments to be made to such Bank
         hereunder or other document satisfactory to the Borrower and the Agent
         indicating that all payments to be made to such Bank hereunder are not
         subject to such taxes and (ii) each other Bank shall provide the Agent
         and the Borrower with a written statement which certifies that such
         Bank is not a non-resident alien or foreign corporation and which
         otherwise satisfies Treasury Regulation Section 1.1441-5(b) or any
         successor regulation under the Internal Revenue Code (each such
         certificate or statement, an "Exemption Certificate"). Unless the Agent
         and the Borrower have received an Exemption Certificate from such Bank,
         the Borrower, or the Agent if the Borrower has not withheld, may
         withhold taxes from such payments at the applicable statutory rate
         (subject, in the case of the Borrower to the requirements of Section 0
         above); provided, however, that, if the Borrower has so withheld, the
         Borrower shall so notify the Agent. If the Borrower is required to pay
         additional amounts to any Bank pursuant to this Section 0, such Bank
         shall use commercially reasonable efforts to designate a different
         Lending Office if such designation will thereafter avoid the need for
         any additional payments under this Section 0 and will not, in the sole
         judgment of such Bank, be otherwise disadvantageous to such Bank. A
         Bank which ceases to be exempt from United States withholding taxes
         shall notify the Agent and the Borrower promptly thereof. If a Bank
         organized under the laws of a jurisdiction other than the United States
         or a political subdivision thereof fails to comply with the provisions
         of this Subsection (f), then the Borrower shall not have any obligation
         to increase the sum payable to such Bank pursuant to this Section 0 or
         to indemnify such Bank for Taxes as provided in this Section.

                  (g) SURVIVAL OF PROVISION. Without prejudice to the survival
         of any other agreement of the Borrower hereunder, the agreements and
         liabilities of the Borrower contained in this Section 0 shall survive
         the payment in full of the Obligations.

                                       71
<PAGE>   80

         10.4     LOSSES. If any payment of principal of, or Rate Conversion or
Rate Continuation of, any LIBOR Rate Loan is not paid when due or is made on a
day other than on the last day of an Interest Period relating to such Loan, as a
result of a payment or Rate Conversion or Rate Continuation pursuant to the
provisions of Section 0 of this Agreement or acceleration of the maturity of the
Revolving Credit Notes pursuant to Section 0 of this Agreement or for any other
reason, the Borrower shall, upon demand by any Bank (with a copy of such demand
to the Agent), pay to the Agent for the account of such Bank any amounts
required to compensate such Bank for any additional losses, costs or expenses
which it may reasonably incur as a result of such payment or Rate Conversion or
Rate Continuation, including, without limitation, any loss, cost or expense
(other than any expenses directly attributable to loan origination efforts)
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Bank to fund or maintain such Loan.

         10.5     INDEMNIFICATION FOR REQUESTS. Whenever the Borrower: (a) shall
revoke any Credit Request, any Rate Conversion/Continuation Request involving

                          SUBSIDIARY GUARANTY AGREEMENT


                  This GUARANTY AGREEMENT (this "Guaranty Agreement") is made as
of the _____ day of _____________, 1998, by [ ___________________], a
__________________ corporation (the "Guarantor"), in favor of National City
Bank, as Agent (the "Agent"), for the benefit of the Banks (as defined below),
the Co-Agent (as defined below) and the Letter of Credit Bank (as defined
below).

                                    RECITALS

                  WHEREAS, the Agent, OM Group, Inc. (the "Borrower"), the banks
which are party thereto (the "Banks"), ABN Amro Bank, N.V., as Co-Agent (the
"Co-Agent") and National City Bank, as Letter of Credit Bank (the "Letter of
Credit Bank"), will enter into that certain Amended and Restated Credit
Agreement (as the same may from time to time be amended or otherwise modified or
supplemented, the "Credit Agreement"), pursuant to which the Banks will make
certain loans and other financial accommodations available to the Borrower;

                  WHEREAS, the Guarantor is a wholly-owned subsidiary of the
Borrower and therefore will benefit from the loans and financial accommodations
made available to the Borrower; and

                  WHEREAS, it is a condition precedent to the Banks' making of
financial accommodations available to the Borrower and the Letter of Credit
Bank's issuing of letters of credit under the Credit Agreement that the
Guarantor shall have executed and delivered this Guaranty Agreement;

                  NOW, THEREFORE, in consideration of these premises and in
order to induce the Banks to make loans and other financial accommodations
available to the Borrower under the Credit Agreement, the Guarantor hereby
agrees with the Agent, for the benefit of the Banks, the Co-Agent and the Letter
of Credit Bank as follows:

                  SECTION 1. Definitions. The capitalized terms used herein
which are defined in the Credit Agreement and not otherwise defined herein are
used herein as therein defined.

                  SECTION 2. Guaranty. The Guarantor hereby unconditionally
guarantees the punctual payment when due, whether at stated maturity, by
acceleration or otherwise, of all obligations the Borrower may now or hereafter
owe to the Agent, the Banks or the Letter of Credit Bank, of every type and
description, including, but not limited to, the Borrower's 

<PAGE>   105

obligations under the Credit Agreement and the Loan Documents (all such
obligations of the Borrower being referred to herein as of the "Guaranteed
Obligations") and agrees to pay any and all expenses (including counsel fees and
expenses) incurred by the Agent, the Banks or the Letter of Credit Bank in
enforcing any rights under this Guaranty Agreement.

                  SECTION 3. Maximum Liability. The maximum liability of the
Guarantor under this Guaranty Agreement shall be the greatest amount which,
after taking into consideration all other valid and enforceable debts and
liabilities of the Guarantor, an applicable court has determined (after any
appeals) would not render the Guarantor insolvent, unable to pay its debts as
they become due, inadequately capitalized for the business which it intends to
conduct, or unable to pay a judgment rendered upon a claim that is the subject
of an action or proceeding pending at the time when the obligations of this
Guaranty Agreement are incurred or increased.

                  SECTION 4. Guaranty Absolute. The Guarantor guarantees that
the Guaranteed Obligations will be paid strictly in accordance with the terms of
the Credit Agreement and the Loan Documents, regardless of any law, regulation
or order now or hereafter in effect in any jurisdiction affecting any of such
terms or the rights of the Agent or the Banks with respect thereto. The
liability of the Guarantor under this Guaranty Agreement shall be absolute and
unconditional irrespective of:

                  (a) any lack of validity or enforceability of the Credit
         Agreement, the Loan Documents or any other agreement or instrument
         relating thereto;

                  (b) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Guaranteed Obligations, or any
         other amendment or waiver of or any consent to departure from the
         Credit Agreement, the Loan Documents or any other agreement or
         instrument relating thereto;

                  (c) any exchange, release or non-perfection of any collateral,
         or any release or amendment or waiver of or consent to departure from
         any other guaranty, for all or any of the Guaranteed Obligations;

                  (d) failure by the Agent or any Bank to take any steps to
         perfect and maintain its or their security interest in, or preserve its
         rights to, any security or collateral for the Guaranteed Obligations;

                  (e) the Agent's or any Bank's election in any proceeding
         instituted under Chapter 11 of Title 11 of the United States Code (11
         U.S.C. Section 101 et seq.) (the "Bankruptcy Code"), or the application
         of Section 1111(b)(2) of the Bankruptcy Code;

                  (f) any borrowing or grant of a security interest under
         Section 364 of the Bankruptcy Code; or



                                       2
<PAGE>   106

                  (g) any other circumstance that might otherwise constitute a
         defense available to, or a discharge of, the Borrower or any guarantor.

This Guaranty Agreement shall continue to be effective or shall be reinstated,
as the case may be, if at any time any payment of any of the Guaranteed
Obligations is rescinded or must otherwise be returned by the Agent, any Bank or
the Letter of Credit Bank upon the insolvency, bankruptcy or reorganization of
the Borrower or otherwise, all as though such payment had not been made.

                  SECTION 5. Waiver. The Guarantor hereby waives promptness,
diligence, notice of acceptance and any other notice with respect to any of the
Guaranteed Obligations and this Guaranty and any requirement that the Agent, any
Bank or the Letter of Credit Bank protect, secure, perfect or insure any
security interest or lien or any property subject thereto or exhaust any right
or take any action against the Borrower or any other person or entity or any
collateral.

                  SECTION 6. Subrogation. The Guarantor shall have no right of
subrogation, reimbursement or contribution and hereby waives any right to
enforce any remedy which the Agent, any Bank or the Letter of Credit Bank now
has or may hereafter have against the Borrower, any endorser or any other
guarantor, of all or any part of the Guaranteed Obligations, and the Guarantor
hereby waives any benefit of, and any right to participate in, any security or
collateral given to the Agent to secure payment of the Guaranteed Obligations or
any other liability of the Borrower to the Agent, the Banks or the Letter of
Credit Bank. The Guarantor also waives all setoffs and counterclaims and all
presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor, and notices of acceptance of this
Guaranty Agreement . The Guarantor further waives all notices of the existence,
creation or incurring of new or additional indebtedness, arising either from
additional loans extended to the Borrower or otherwise, and also waives all
notices that the principal amount, or any portion thereof, and/or any interest
on any instrument or document evidencing all or any part of the Guaranteed
Obligations is due, notices of any and all proceedings to collect from the
maker, any endorser or any other guarantor of all or any part of the Guaranteed
Obligations, or from anyone else, and, to the extent permitted by law, notices
of exchange, sale, surrender or other handling of any security or other
collateral given to the Agent or any Bank to secure payment of the Guaranteed
Obligations.

                  SECTION 7. Financial Condition of Borrower. The Guarantor
hereby assumes responsibility for keeping itself informed of the financial
condition of the Borrower and of all circumstances bearing upon the risk of
nonpayment of the Guaranteed Obligations or any part thereof that diligent
inquiry would reveal and the Guarantor hereby agrees that neither the Agent nor
any Bank shall have any duty to advise the Guarantor of information known to the
Agent or any such Bank regarding such condition or any such circumstances. In
the event the Agent or any Bank, in its sole discretion, undertakes at any time
or from time to time to provide any such information to the Guarantor, neither
the Agent or such Bank shall be under any obligation (i) to undertake any
investigation not a part of its regular business routine (ii) to disclose any



                                       3
<PAGE>   107

information which, pursuant to accepted or reasonable commercial finance
practices, the Agent or such Bank wishes to maintain confidential or (iii) to
make any other or future disclosures of such information or any other
information to the Guarantor.

                  SECTION 8. Marshalling of Assets. The Guarantor consents and
agrees that the Agent, the Banks and the Letter of Credit Bank shall not be
under any obligation to marshall any assets in favor of the Guarantor or against
or in payment of any or all of the Guaranteed Obligations. The Guarantor further
agrees that, to the extent that the Borrower makes a payment or payments to the
Agent, any Bank or the Letter of Credit Bank, or the Agent, any Bank or the
Letter of Credit Bank receives any proceeds of collateral, which payment or
payments or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside and/or required to be repaid to Borrower,
its estate, trustee, receiver or any other party, including, without limitation,
the Guarantor, under any bankruptcy law, state or federal law, common law or
equitable cause, then to the extent of such payment or repayment, the Guaranteed
Obligations or part thereof which has been paid, reduced or satisfied by such
amount shall be reinstated and continued in full force and effect as of the date
such initial payment, reduction or satisfaction occurred.

                  SECTION 9. Representations and Warranties; Incumbency.

the Revolving Credit Commitment remains outstanding, the Guarantor will not,
without the prior written consent of the Agent, for the benefit of the Banks:

         create or suffer to exist any lien, security interest or other charge
         or encumbrance, upon or with respect to any of its properties, whether
         now owned or hereafter acquired, or assign any right to receive income,
         in each case to secure any Indebtedness of any Person.

                  (b) Sales, Etc. of Assets. Except as permitted by the Credit

and the Letter of Credit Bank, is hereby authorized, without notice or demand

                  At any time upon the occurrence and during the continuation of
an Event of Default, the Agent, any Bank or the Letter of Credit Bank may, in
its sole discretion, without notice to the Guarantor and regardless of the
acceptance of any security or collateral for the payment hereof, appropriate and
apply toward the payment of the Guaranteed Obligations (i) any indebtedness due
or to become due from the Agent, any Bank or the Letter of Credit Bank to the



                                       5
<PAGE>   109

Guarantor, and (ii) any moneys, credits or other property belonging to the
Guarantor, at any time held by or coming into the possession of the Agent, any
Bank or the Letter of Credit Bank.

                  SECTION 12. Amendments, Etc. No amendment or waiver of any
provisions of this Guaranty Agreement nor consent to any departure by the
Guarantor therefrom shall in any event be effective unless the same shall be in
writing and signed by the Agent and all of the Banks, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. No release or termination of this Guaranty Agreement
shall be effected unless the same shall be in writing and executed by the Agent.

                  SECTION 13. No Waiver; Remedies. No failure on the part of the
Agent or any Bank or the Letter of Credit Bank to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

                  SECTION 14. Right of Set-off. Upon the occurrence and during
the continuance of any Event of Default, the Agent, each Bank and the Letter of
Credit Bank is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by the Agent, such Bank or the Letter of
Credit Bank to or for the credit or the account of the Guarantor against any and
all of the obligations of the Guarantor now or hereafter existing under this
Guaranty Agreement, irrespective of whether or not the Agent, such Bank or the
Letter of Credit Bank shall have made any demand under this Guaranty Agreement
and although such obligations may be contingent and unmatured. The Agent, each
such Bank and the Letter of Credit Bank agrees promptly to notify the Guarantor
after any such set-off and application made by the Agent, such Bank or the
Letter of Credit Bank, as the case may be, provided that the failure to give
such notice shall not affect the validity of such set-off and application. The
rights of the Agent, each Bank and the Letter of Credit Bank under this Section
14 are in addition to other rights and remedies (including, without limitation,
other rights of set-off) which the Agent, such Bank or the Letter of Credit Bank
may have.

                  SECTION 15. Continuing Guaranty; Transfer of Advances. This
Guaranty Agreement is a continuing guaranty and shall (i) remain in full force
and effect until the Guaranteed Obligations are paid in full and each Bank's
Revolving Credit Commitment is terminated, and shall continue in effect
thereafter until this Guaranty Agreement is revoked prospectively as to future
transactions by written notice to that effect actually received by the Agent
(but such notice shall not be effective as to any Guaranteed Obligations or the
Revolving Credit Commitment outstanding at that time, any additional interest,
premiums or fees to become payable with respect thereto or any renewals,
extensions, or refinancings of the same), (ii) be binding upon the Guarantor,
its successors and assigns, and (iii) inure to the benefit of and be enforceable
by the Agent and its successors, transferees and assigns. Without limiting the



                                       6
<PAGE>   110

generality of the foregoing clause (iii), subject to the limitations, if any,
set forth in the Credit Agreement, the Agent and each Bank may assign or
otherwise transfer any portion of the Advances held by it to any other person or
entity, and such other person or entity shall thereupon become vested with all
the rights in respect thereof granted to the Agent herein or otherwise.

                  SECTION 16. Addresses for Notices. All notices and other
communications provided for hereunder shall be in writing (including telecopy,
telegraphic, telex or cable communication) and mailed, telecopied, telegraphed,
telexed, cabled or delivered, if to the Guarantor, at its address shown below
its signature hereto; and if to the Agent, at its address specified in the
Credit Agreement, or as to each party at such other address as shall be
designated by such party in a written notice to the other party. All such
notices and other communications shall, when mailed, telecopied, telegraphed,
telexed or cabled, be effective five (5) Business Days after deposit in the
mails, and on the date telecopied, delivered to the telegraph company, confirmed
by telex answerback or delivered to the cable company, respectively.

                  SECTION 17. Solvency. The Guarantor is solvent (as described
in the Guarantor Credit Agreement). The Guarantor does not believe that final
judgments, if any, against the Guarantor in actions for money damages presently
pending will be rendered at a time when, or in an amount such that, the
Guarantor will be unable to satisfy any such judgments promptly in accordance
with their terms (taking into account the maximum reasonable amount of such
judgments in any such actions and the earliest reasonable time at which such
judgments might be rendered). The cash flow of the Guarantor, after taking into
account all other anticipated uses of the cash of the Guarantor (including the
payments on or in respect of debt referred to in this Section 17), will at all
times be sufficient to pay all such judgments promptly in accordance with their
terms.

                  SECTION 18. Waiver of Jury Trial. THE PARTIES ACKNOWLEDGE AND
AGREE THAT ANY CONTROVERSY THAT MAY ARISE UNDER THIS GUARANTY AGREEMENT, THE
CREDIT AGREEMENT OR THE LOAN DOCUMENTS (AS DEFINED IN THE CREDIT AGREEMENT)
WOULD INVOLVE DIFFICULT AND COMPLEX ISSUES AND THEREFORE AGREE THAT ANY LAWSUIT
GROWING OUT OF OR INCIDENTAL TO ANY SUCH CONTROVERSY WILL BE TRIED IN A COURT OF
COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

SECTION 19. Jurisdiction; Venue; Inconvenient Forum.

                  (a) Jurisdiction. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE
NONEXCLUSIVE JURISDICTION OF ANY OHIO STATE COURT OR FEDERAL COURT OF THE UNITED
STATES OF AMERICA SITTING IN CUYAHOGA COUNTY, OHIO, AND ANY APPELLATE COURT FROM
ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
GUARANTY AGREEMENT, THE CREDIT AGREEMENT OR THE LOAN DOCUMENTS, 



                                       7

OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES
HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT
OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH OHIO
STATE OR, TO THE EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT. EACH OF THE
PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING
SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.

                  (b) Venue; Inconvenient Forum. EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY
LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE
TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS GUARANTY AGREEMENT, THE CREDIT AGREEMENT OR ANY LOAN DOCUMENT
IN ANY OHIO STATE OR FEDERAL COURT SITTING IN CUYAHOGA COUNTY, OHIO. EACH OF THE
PARTIES HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE
DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING
IN ANY SUCH COURT. THE GUARANTOR CONFIRMS THAT THE FOREGOING WAIVERS ARE
INFORMED AND FREELY MADE.

                  SECTION 20. Governing Law. This Guaranty shall be governed by,
and construed in accordance with, the laws of the State of Ohio.

                            BANK ASSIGNMENT AGREEMENT

                  This Assignment Agreement (this "Assignment Agreement")
between _____________________________________________________________________
(the "Assignor") and ________________________________________ (the "Assignee")
is dated as of ________________, 19___. The parties hereto agree as follows:

                  1. PRELIMINARY STATEMENT. The Assignor is a party to an
Amended and Restated Credit Agreement, dated as of January 30, 1998 (which, as
it may be amended, modified, renewed or extended from time to time, is herein
called the "Credit Agreement"), among OM Group, Inc. (the "Borrower"), the banks
which are signatories thereto (the "Banks"), ABN Amro Bank N.V., as Co-Agent
(the "Co-Agent"), National City Bank as Letter of Credit Bank (the "Letter of
Credit Bank"), and National City Bank as agent for the Banks and the Letter of
Credit Bank (the "Agent"). Capitalized terms used herein and not otherwise
defined herein shall have the meanings attributed to them in the Credit
Agreement. The Assignor desires to assign to the Assignee, and the Assignee
desires to assume from the Assignor, an undivided interest (the "Purchased
Percentage") in the Revolving Credit Commitment of the Assignor such that after
giving effect to the assignment and assumption hereinafter provided, the
Revolving Credit Commitment of the Assignee shall equal ________________________
Dollars ($___________) and its percentage of the aggregate amount of the
Revolving Credit Commitments shall equal ________________________ percent
(____%).

                  2. ASSIGNMENT. For and in consideration of the assumption of
obligations by the Assignee set forth in Section 3 hereof and the other
consideration set forth herein, and effective as of the Effective Date (as
hereinafter defined), the Assignor does hereby sell, assign, transfer and convey
all of its right, title and interest in and to the Purchased Percentage of (i)
the Revolving Credit Commitment of the Assignor (as in effect on the Effective
Date), (ii) any Revolving Credit Loan made by the Assignor which is outstanding
on the Effective Date, (iii) the Assignor's Ratable Portion of each Letter of
Credit, (iv) any Note delivered to the Assignor pursuant to the Credit
Agreement, and (v) the Credit Agreement and the other Loan Documents. Pursuant
to Section 9.1(d) of the Credit Agreement, on and after the Effective Date the
Assignee shall have the same rights, benefits and obligations as the Assignor
had under the Loan Documents with respect to the Purchased Percentage of the
Loan Documents, all determined as if the Assignee were a "Bank" under the Credit
Agreement with ____________________ Dollars ($_____________) equaling
_____________ percent (_____%) of the aggregate amount of the Revolving Credit
Commitments. The Effective Date (the "Effective Date") shall be two Business
Days (or such shorter period agreed to by the Agent) after a Notice of
Assignment substantially in the form of Attachment I hereto and any consents
substantially in the form of Attachment II hereto required to be delivered to
the Agent by Section 9.1(b) of the Credit Agreement have been delivered to the
Agent; provided, however, that, in the event that the Borrower shall
appropriately deliver a Credit Request prior to the time at which all of
conditions

to the effectiveness of this Assignment shall have been met, the Effective Date
shall be the Business Day immediately following the day upon which the Advances
by the Bank are to be made under such Credit Request. In no event will the
Effective Date occur if the payments required to be made by the Assignee to the
Assignor on the Effective Date under Section 4 are not made on or prior to the
proposed Effective Date. The Assignor will notify the Assignee of the proposed
Effective Date on the Business Day prior to the proposed Effective Date and will
notify the Assignee of any pending Credit Request which would delay such
proposed Effective Date.

                  3. ASSUMPTION. For and in consideration of the assignment of
rights by the Assignor set forth in Section 2 hereof and the other consideration
set forth herein, and effective as of the Effective Date, the Assignee does
hereby accept that assignment, and assume and covenant and agree fully,
completely and timely to perform, comply with and discharge, each and all of the
obligations, duties and liabilities of the Assignor under the Credit Agreement
which are assigned to the Assignee hereunder, which assumption includes, without
limitation, the obligation to fund the unfunded portion of the aggregate amount
of the Revolving Credit Commitments in accordance with the provisions set forth
in the Credit Agreement and to participate in the Letters of Credit pursuant to
its Ratable Portion thereof as if the Assignee were a "Bank" under the Credit
Agreement with ______________________ Dollars ($_______________) equaling
____________ percent (______%) of the aggregate amount of the Revolving Credit
Commitments. The Assignee agrees to be bound by all provisions relating to
"Bank" under and as defined in the Credit Agreement, including, without
limitation, provisions relating to the dissemination of information and the
payment of indemnification.

                  4. PAYMENTS OBLIGATIONS. On and after the Effective Date, the
Assignee shall be entitled to receive from the Agent all payments of principal,
interest and fees with respect to the Purchased Percentage of the Assignor's

Advances made by the Assignor accrued for periods prior to the Effective Date
and not heretofore paid by the Assignee to the Assignor. In the event that
either party hereto receives any payment to which the other party hereto is
entitled under this Assignment Agreement, then the party receiving such amount
shall promptly remit it to the other party hereto.

                  8. SUBSEQUENT ASSIGNMENTS. After the Effective Date, the
Assignee shall have the right pursuant to Section 9.1 of the Credit Agreement to
