respective Subsidiaries, whether pursuant to this Agreement or otherwise
(and, if so used, the respective equity contribution shall not constitute a
Designated Capital Contribution).  For avoidance of doubt, it is understood

exercise of Cure Rights pursuant to Section 7.02, (x) any amounts
constituting Capital Call Contributions, (y) any amounts constituting Special
Capital Contributions or (z) any amounts received from the issuance and sale

(although the occurrence of the Second Amendment Effective Date shall not
release Holdings, the Borrower, any other Loan Party or any other relevant

the sum of the aggregate principal amount of outstanding Term Loans (if any)
of such Lender plus the Revolving Credit Commitment (if any) and the Growth
Capital Commitment (if any) of such Lender, in each case on such date.  All
fees payable as described in the immediately preceding sentence shall not be
subject to counterclaim or set-off for, or be otherwise affected by, any
claim or dispute relating to any other matter and shall be paid to the
Administrative Agent on, or within one Business Day after, the Second
Amendment Effective Date, with the Administrative Agent to distribute such
fees to the various Lenders as described above; it being understood and
agreed, however, that notwithstanding anything to the contrary set forth
above, such fees shall not be payable if the Second Amendment Effective Date
does not occur.

duplication, (x) Category III Capital Call Amounts theretofore actually paid
and applied in accordance with the provisions of Sections 2 and 3 hereof with
respect to one or more previously occurring Category III-A Capital Call
Events and/or Category III-B Capital Call Events and (y) any Special Capital
Contribution Credit as then in effect) of cash equal to the Maximum Growth
Capital Loan Amount as then in effect; provided that (A) in the case of a
Category III-A Capital Call Event, the Category III Capital Call Amount with
respect thereto shall mean an amount of cash equal to the least of (x) the
Category III Capital Call Amount as then in effect (determined without regard
to this proviso, i.e., as reduced only pursuant to the first parenthetical
set forth in this definition), (y) $50,000,000 and (z) that amount of dollars
which is necessary to be subtracted from Total Net Debt to cause the Net

Maximum Permitted Net Leverage Ratio (which determination of Net Leverage
Ratio shall be made in accordance with the Credit Agreement on the basis of
(I) Total Net Debt as of such date and (II) EBITDA for the period of four
consecutive fiscal quarters of the Borrower ended on such date) and (B) in
the case of a Category III-B Capital Call Event, the Category III Capital
Call Amount with respect thereto shall mean an amount of cash equal to the

the Net Leverage Ratio as provided above, in no event shall any effect be
given to any exercise of Cure Rights pursuant to Section 7.02 of the Credit
Agreement (i.e., any increases to EBITDA pursuant to Section 7.02(a) of the
Credit Agreement shall have no effect (and shall not increase EBITDA) in
measuring the Net Leverage Ratio) and (ii) except as expressly provided in
the first sentence of this definition, the Category III Capital Call Amount
shall not be subject to any reduction or diminution in whole or in part for
any reason whatsoever (including without limitation on account of (x) receipt

Call Investors or otherwise), (y) receipt of any Designated Capital
Contributions and/or (z) contributions to capital to effect any exercise of
Cure Rights pursuant to Section 7.02 of the Credit Agreement).

each Test Period occurring after such Test Period shall constitute a Category
III Capital Call Event Test Period for all purposes under this Agreement
until such time, if any, as when no Category III Capital Call Events shall

Contributions previously applied to reduce any Capital Call Amounts required
to be paid and applied hereunder.  Notwithstanding the foregoing to the

                                      -8-

contrary, on any date of determination, the Special Capital Contribution

jointly agrees on an absolute, irrevocable and unconditional basis that:

          (i)  within 14 days after any occurrence of a Category I Capital
     Call Event (provided that if such Category I Capital Call Event shall

     equal to its Capital Call Percentage of the Category I Capital Call
     Amount (determined as of the date of the occurrence of such Category I
     Capital Call Event) with respect to such Category I Capital Call Event;

          (ii)  within 14 days after any occurrence of a Category II Capital

     on or prior to the application of the Category II Capital Call Amount
     with respect to such Category II Capital Call Event, it will make a
     payment (in cash) directly to the Administrative Agent in an amount
     equal to its Capital Call Percentage of the Category II Capital Call
     Amount (determined as of the date of the occurrence of such Category II

     Financial Officer of the Borrower on behalf of the Borrower) in respect
     of the respective Test Period being tested are made available pursuant
     to Section 5.04 of the Credit Agreement; provided, however, in any event
     such Designated Capital Call Investor shall be required to make such
     payment in respect of a Category II-A Capital Call Event to the
     Administrative Agent on or prior to October 31, 2000 unless a road show
     with respect to one or more registered public offerings of common equity
     of Holdings shall have been completed on or after October 17, 2000 and
     prior to October 31, 2000, in which case such Designated Capital Call
     Investor shall be required to make such payment to the Administrative
     Agent on or prior to the later to occur of (x) October 31, 2000 and (y)

                                      -9-

<PAGE>

     14 days after the completion of such road show with respect to one or
     more registered public offerings of common equity of Holdings; and

          (iii)  within 14 days after any occurrence of a Category III
     Capital Call Event, provided that no Category I Capital Call Event has
     occurred on or prior to the application of the Category III Capital Call
     Amount with respect to such Category III Capital Call Event, it will
     make a payment (in cash) directly to the Administrative Agent in an
     amount equal to its Capital Call Percentage of the Category III Capital
     Call Amount (determined as of the date of the occurrence of such
     Category III Capital Call Event) with respect to such Category III
     Capital Call Event; it being understood and agreed that, in the case of
     a Category III-A Capital Call Event, such 14-day period shall begin on
     the date on which financial statements (and as certified by an
     accounting firm or Financial Officer of the Borrower on behalf of the
     Borrower) in respect of the respective Test Period being tested are made
     available pursuant to Section 5.04 of the Credit Agreement.

          (b)  To the extent the Designated Capital Call Investors are
     prohibited by operation of law from making Investments in Investor LP
     (which are contributed by Investor LP to the equity capital of Holdings
     which are further contributed by Holdings to the equity capital of the
     Borrower) as contemplated by Section 3(a) below due to any bankruptcy or
     similar proceeding relating to Investor LP or Holdings (or any of
     Holdings' Subsidiaries) or for any other reason whatsoever, then, at the
     election of the Administrative Agent (with the consent of the Required
     Lenders) (except that in the case of a bankruptcy or similar proceeding
     relating to Investor LP, Holdings or the Borrower, such election of the
     Administrative Agent (with the consent of the Required Lenders) shall
     automatically and immediately be deemed to have been made), the
     Designated Capital Call Investors' respective Investments shall instead
     be promptly made by means of the purchase by such Designated Capital
     Call Investors from each of the Lenders of a subordinated participation
     in such Lenders' outstanding Loans (including such Lenders'
     participations in outstanding Swingline Loans and Letters of Credit),
     pro rata among the Lenders based on their respective Proportionate
     Shares at such time, with such participations to be evidenced by a
     subordinated participation agreement in form and substance satisfactory
     to the Administrative Agent (it being expressly understood and agreed
     (and the subordinated participation agreement shall provide) that no
     payment or distribution of any kind or character, whether in cash,
     property, securities or otherwise, shall be made under any circumstances
     whatsoever with respect to any such subordinated participation until the
     date on which (i) all Commitments and Letters of Credit under the Credit
     Agreement shall have been terminated, (ii) all Obligations (except those
     evidenced by the subordinated participations purchased pursuant to this
     Section 2(b)) shall have been paid in full in cash in accordance with

                                     -10-

     the requirements of the Credit Agreement (or the other Loan Documents)
     or the Interest Rate Protection Agreements, as the case may be, (iii)
     all Interest Rate Protection Agreements shall have been terminated and
     (iv) all Obligations (as defined in the Senior Subordinated Note
     Indenture and, for avoidance of doubt, including without limitation all
     obligations for principal, premium, interest, penalties, fees,
     indemnification, reimbursements, damages and other liabilities under the
     Senior Subordinated Note Indenture) on the Senior Subordinated Notes
     shall have been paid in full in cash (or such other payment provided for
     to the satisfaction of the holders of the Senior Subordinated Notes)).
     For avoidance of doubt, it is understood and agreed that, with respect
     to any obligations of the Designated Capital Call Investors to make
     payments to the Administrative Agent at any time pursuant to Section
     2(a) above (the "Subject Obligations"), to the extent such payments
     required to be made by the Designated Capital Call Investors pursuant to
     Section 2(a) above on account of such Subject Obligations shall have
     been made by the Designated Capital Call Investors and applied (or
     deemed to be applied) in the manner described in the preceding
     provisions of this Section 2(b) (i.e., by means of purchase by the
     Designated Capital Call Investors from each of the Lenders of a
     subordinated participation in such Lenders' outstanding Loans (including
     such Lenders' participations in outstanding Swingline Loans and Letters
     of Credit) in the manner described, and under the circumstances set
     forth, in the preceding provisions of this Section 2(b)), no further
     payments on account of such Subject Obligations (unless and then to the
     extent the respective payments on account of such purchases of
     subordinated participations are for any reason whatsoever required to be
     returned or disgorged to Investor LP or the Designated Capital Call
     Investors) shall be required to be made by the Designated Capital Call
     Investors pursuant to Section 2(a) above and applied (or deemed to be
     applied) in the manner described in Section 3(a) hereof."

          3.  Section 3(b) of the Capital Call Agreement is hereby amended by
deleting clause (ii) thereof in its entirety and inserting in lieu thereof
the following new clause (ii):

          "(ii)  to the extent that payments are not required to be applied
pursuant to preceding clause (i), the Administrative Agent shall, on behalf
of the Borrower, promptly apply same directly to the repayment of Term Loans
pursuant to Section 2.12(c) of the Credit Agreement (and in accordance with
paragraphs (b) and (d) of Section 2.11 of the Credit Agreement); provided
that if the Borrower shall have given the Administrative Agent notice that
the payments are to be applied to prepay outstanding principal of Swingline
Loans, Revolving Credit Borrowings and/or Growth Capital Borrowings, the
amount to be applied pursuant to this clause (ii) to repay Term Loans as
otherwise provided above shall be reduced by the amount to be so applied to

                                     -11-

such voluntary prepayments (in which event the Administrative Agent shall
directly apply such funds to make the requested voluntary prepayments)."

deleting clause (a) thereof in its entirety and inserting in lieu thereof the
following new clause (a):

     "(a)  This Agreement and the security interests created hereby shall
     terminate and be of no further force and effect (except to the extent
     any party's obligations, if any, arising prior to such time hereunder
     have not theretofore been fulfilled) upon the earliest of:

          (i)  the occurrence of a Category I Capital Call Event and the
     making of all of the required payments, if any, by each of the
     Designated Capital Call Investors as a result thereof (including,
     without limitation, any related interest under Section 20) to the
     Administrative Agent (including by means of purchase of subordinated
     participations from the Lenders pursuant to Section 2(b) above)
     (irrespective of whether any of the events and conditions described in
     clauses (v) and (vi) of the definition of "Capital Call Event" set forth
     herein shall subsequently occur or exist);

          (ii)  the date on which the sum of (A) the aggregate Capital Call
Amounts theretofore paid and applied (including by way of purchase and sale
of subordinated participation interests) in accordance with Sections 2 and 3
hereof with respect to all Capital Call Events and (B) the aggregate amount
of Special Capital Contributions theretofore actually made and applied in
accordance with the definition of "Special Capital Contributions" set forth
in the Credit Agreement, shall be equal to $100,000,000, so long as all
related required payments of interest under Section 20 have theretofore been
made;

          (iii)  the first date after the last day of the fiscal quarter of
the Borrower ending closest to June 30, 2001 on which (x) no default in the
due performance on the part of any of the Designated Capital Call Investors
of any payment obligation relating to any Category I Capital Call Events or
Category II Capital Call Events (including any related interest under Section
20) shall exist and (y) at least $50,000,000 (as reduced by any Special
Capital Contribution Credits which have not been applied to reduce any
Category I Capital Call Amounts or Category II Capital Call Amounts) shall
have been theretofore paid and applied (including by way of purchase and sale
of subordinated participation interests) in accordance with Sections 2 and 3
hereof with respect to all Category III Capital Call Events, so long as all
related required payments of interest under Section 20 have theretofore been
made; and

                                     -12-

          (iv)  the date on which all Commitments and Letters of Credit under
the Credit Agreement shall have been terminated, all Obligations shall have
been repaid in full in cash in accordance with the requirements of the Credit
Agreement (or the other Loan Documents) or the Interest Rate Protection
Agreements, as the case may be, and all Interest Rate Protection Agreements
shall have been terminated."

          5.  Section 20 of the Capital Call Agreement is hereby amended by
inserting, immediately at the end of the first sentence thereof, the
following new proviso: "; provided that, notwithstanding the foregoing to the
contrary, if any of the Designated Capital Call Investors, Investor LP,
Holdings or the Borrower shall default in the payment of any Category I
Capital Call Amount or Category III Capital Call Amount, such person shall on
demand from time to time pay interest, to the extent permitted by law,
directly to the Administrative Agent on such defaulted amount (except that
with respect to any such default in the payment of any Category I Capital
Call Amount, (A) interest thereon shall be determined pursuant to this
proviso only in respect of that amount which is the lesser of (i) such
Category I Capital Call Amount and (ii) the Maximum Growth Capital Amount (as
in effect at the time of the calculation of such Category I Capital Call
Amount in accordance with the terms hereof) and (B) interest thereon shall be
determined pursuant to the provisions of this Section 20 without regard to
this proviso in respect of that amount, if any, by which such Category I
Capital Call Amount shall exceed the amount with respect to which interest
thereon is determined pursuant to preceding clause (A) of this proviso) for
the period beginning on the date of such default up to (but not including)
the date of actual payment (after as well as before judgment) at a rate per
annum (computed on the basis of the actual number of days elapsed over a year
of 360 days) equal to the greater of (x) 2% per annum in excess of the rate
applicable to Growth Capital Revolving Loans maintained as ABR Loans
(assuming same are outstanding under the Credit Agreement) from time to time
and (y) the rate which is 2% in excess of the rate then borne by such Loans
(assuming same are outstanding under the Credit Agreement)."

II.  Miscellaneous.

          1.  The parties hereto acknowledge and agree that, as a result of
the modifications to the Capital Call Agreement made pursuant to this
Amendment, the aggregate amounts the Designated Capital Call Investors could
be obligated (under certain circumstances) to pay pursuant to this Agreement

          2.  Without limiting the provisions of Section 8 of the Capital
Call Agreement, each of the parties hereto acknowledges and agrees that the
Credit Agreement may be amended, modified or changed or any conditions to the
incurrence of one or more Growth Capital Revolving Loans thereunder waived

                                     -13-

<PAGE>

this Capital Call Agreement), even if the effect thereof is to increase the
obligations of the Designated Capital Call Investors pursuant to the Capital
Call Agreement as a result of an increase to the Capital Call Amount in
accordance with the definition thereof contained in the Capital Call
Agreement or the addition of one or more Category III Capital Call Event Test
Periods as a result thereof.

          3.  In order to induce the Lenders to enter into the Second
Amendment to Credit Agreement, each of the Designated Capital Call Investors,
Investor LP, Holdings and the Borrower hereby represents, warrants and
confirms to each of the Lenders and agrees that (i) all representations and
warranties contained in Section 10 of the Capital Call Agreement are true and

exists no Capital Call Event on the date hereof after giving effect to this
Amendment and (iii) promptly following any request from the Administrative
Agent (and in any event within 60 days after receiving any such request), it

Administrative Agent to protect and preserve any security interests created,
or intended to be created, pursuant to the Capital Call Agreement.

          4.  This Amendment is limited as specified and shall not constitute
a modification, acceptance or waiver of any other provision of the Capital
Call Agreement or any related document.

          5.  This Amendment may be executed in any number of counterparts
and by the different parties hereto on separate counterparts, each of which

                                     -18-Summary of Permitted Indebtedness, Commitments from Banks,
                       and Availability at March 31, 2000
                                 (in thousands)

Capitalized  terms not  otherwise  defined in this summary are defined as in the
Indenture.

Pursuant to Section 4.10 of the  Indenture  between  International  Knife & Saw,
Inc.  (the  "Company")  and United  States Trust Company of New York as Trustee,
dated  November 6, 1996,  the Company shall not incur directly or indirectly any
Indebtedness  unless  certain  cash flow  coverage  ratios  are  achieved.  This
limitation, however, does not apply to Permitted Indebtedness.

Permitted  Indebtedness  includes  Indebtedness of the Company arising under the
Senior  Credit  Facility  and  Indebtedness  of IKS  Klingelnberg  GmbH  and its
Subsidiaries  arising under the German  Subsidiary  Facilities,  in an aggregate
principal  amount  not to  exceed at any time  outstanding  the  greater  of (x)
$30,000,  less any permanent  reduction in commitments  thereunder,  and (y) the
sum, at such time,  of (i) 85% of the  consolidated  book value of net  accounts
receivable of the Company and the  Restricted  Subsidiaries  and (ii) 60% of the
consolidated  book  value  of  inventory  of  the  Company  and  the  Restricted
Subsidiaries.

According to the formula referred to above,  Permitted Indebtedness at March 31,
2000 is equal to $42,884.  The Company has commitments  from banks in the amount
of $40,002. These commitments are broken down as follows:

Deutsche Bank AG has provided a $13,000 line of credit to International  Knife &
Saw, Inc. under the Senior Credit Facility. This facility was initially $20,000,
but was modified and partially  replaced with the unsecured  line of credit from
the Fifth Third Bank of Northern Kentucky,  Inc. As of March 31, 2000, $2,859 of
the Senior Credit Facility was used and $10,141 was unused.  Collateral for this
facility  includes  inventories  and  accounts  receivable.  Covenants  for this
facility  are  described in the letter  agreement  with  Deutsche  Bank AG dated
October 8, 1996.  This letter  agreement was filed by the Company in its Amended
Registration  Statement  on Form S-4  filed  with the  Securities  and  Exchange
Commission on January 28, 1997.

Fifth Third Bank of Northern  Kentucky,  Inc. has  provided an unsecured  $1,500
line of credit to  International  Knife & Saw,  Inc.  This  facility  replaced a
portion  of the  Senior  Credit  Facility.  As of March 31,  2000,  $775 of this
facility was used and $725 was unused.

Deutsche  Bank AG has  provided  a DEM  68,000  ($33,275)  line of credit to IKS
Klingelnberg  GmbH  ("GmbH")  under  the  German  Subsidiary  facilities.  These
facilities  encompass  a) a guarantee by Deutsche  Bank AG of GmbH's  promissory
note in the  amount  of DEM  3,599  ($1,761)  to a former  owner of the  Diacarb
company (this debt has been incurred  pursuant to section  4.10(b)(xiii)  of the
Indenture);  b) assumed debt, for

which GmbH serves as guarantor,  in the amount of ATS 44,000  (approximately DEM
5,718 or $2,798) on the books of and in connection  with GmbH's  acquisition  of
Boehler Miller Messer und Saegen GmbH in January 2000; c)  Indebtedness  of GmbH
which was outstanding on the Issue Date in the amount of approximately DEM 6,566
($3,213); and d) a general line of credit in the amount of DEM 52,117 ($25,503).
Of this  general  line of credit in the  amount of DEM 52,117  ($25,503),  as of
March 31,  2000,  DEM 35,826  ($17,531)  of the facility was used and DEM 16,291
($7,972) was unused. Collateral and covenants for this facility are described in
the letter  agreement  with Deutsche Bank AG dated October 8, 1996.  This letter
agreement was filed by the Company in its Amended Registration Statement on Form
S-4 filed with the Securities and Exchange Commission on January 28, 1997.
