Representative shall give Bank irrevocable  telephonic notice, written notice or
telecopied  notice by no later than 11:00  a.m.,  Chicago  time,  on the date it
requests Bank to make a Base Rate Loan hereunder. Representative shall give Bank
irrevocable  telephonic  notice  (which  notice  shall be promptly  confirmed in
writing) no later than 10:00 a.m.,  Chicago time,  three (3) Business Days prior
to the date that it  requests  Bank to make a LIBOR Loan  hereunder  or effect a

receipt  by Bank  and  shall  specify  the date of the  Loan  (which  shall be a
Business Day), the amount of such Loan,  whether the Loan is a Base Rate Loan or
LIBOR Loan and,  with respect to a LIBOR Loan,  the Interest  Period  applicable
thereto.  Representative  agrees  that Bank may rely on any notice  given by any
person it  reasonably  believes to be an  Authorized  Officer of  Representative
without the necessity of independent investigation. Each borrowing shall be on a
Business  Day.  Notwithstanding  anything  contained  in this  Agreement  to the
contrary,  the Borrowers  hereby  appoint K-V (the  "Representative")  to act as
their sole and exclusive  representative  under this Agreement for all purposes,
including without limitation,  to receive funds advanced  hereunder,  to receive
notices and other  communications from the Bank hereunder,  to make requests for
advances of funds hereunder and to amend this Agreement. The Bank shall have (i)
no obligation to  communicate  with any Borrower  other than the  Representative
concerning  this  Agreement,  any  note  or any  matter  related  to  Borrowers'

or cause to be  issued,  Letters of Credit  for the  account  of such  Borrower;
provided that the aggregate face amount of all Letters of Credit  outstanding at
any  time  shall  not  exceed  the  availability   under  the  Revolving  Credit
Commitment.  No  Letter  of Credit  may have an  expiration  date that is either
greater  than one (1) year from the date of issuance of such Letter of Credit or
later than the Letter of Credit  Termination  Date.  Any amounts paid by Bank in
connection  with any  Letter  of  Credit  (i) shall  become  part of  Borrowers'
Liabilities,  (ii) shall be paid from the proceeds of a Revolving Loan requested
pursuant  to  Paragraph  2.1 above,  to the extent  Bank is  required  to make a
Revolving  Loan  pursuant to the terms  hereof,  and (iii)  otherwise,  shall be
payable on demand.  In no event  shall Bank be  required to issue or cause to be
issued  Letters  of Credit at any time  there  exists an Event of  Default or an
event which with  passage of time or giving of notice or both would  mature into
an Event of Default.

                   (b) K-V and any  Subsidiary  for  whose  account  a Letter of
Credit is issued, jointly and severally,  agree to unconditionally,  irrevocably
and  absolutely  pay  immediately  to Bank the  amount  drawn  under a Letter of
Credit. If any Borrower at any time fails to make such payment,  Borrowers shall

                                       14


be deemed to have elected to borrow from Bank on such date Revolving Loans equal
in aggregate amount to the amount paid by Bank under such Letter of Credit.

all of the  conditions  precedent to making the Term Loan described in Paragraph
5.5 and 6.1(B) are satisfied,  K-V shall give Bank irrevocable telephonic notice

Chicago time,  two (2) Business Days prior to the date K-V requests Bank to make

amount owing and unpaid on the Revolving  Note and the Term Note. The failure to
so record any such amount or any error in so recording any such amount shall not
limit or otherwise  affect the  obligations of Borrowers  hereunder or under the

together with all interest accrued thereon.

         4.1       Applicable Borrowing Amounts; Interest Rates; Default Rate

                   (a)  Borrowers  hereby  promise to pay interest on the unpaid
principal  amount of each  Revolving  Loan at a rate per annum equal to the Base
Rate  from  time to  time in  effect  (the  "Base  Rate  Loan")  for the  period
commencing  on the date of such Loan until such Base Rate Loan is (A)  converted
to a LIBOR Loan pursuant to Paragraph 4.3 hereof,  or (B) paid in full.  Accrued
interest  on the  outstanding  principal  amount of Loans  shall be payable  (i)
monthly in arrears on the last Business Day of each  calendar  month in the case
of a Base Rate Loan,  (ii) on the last day of the applicable  Interest Period in
the case of a LIBOR Loan,  (iii) upon  conversion  of any Loan into a LIBOR Loan
(such amount of accrued  interest then coming due to be calculated  based on the
principal  amount of the Loan so converted)  and (iv) upon the Revolving  Credit
Termination  Date  (in the  case of a  Revolving  Loan),  which  payments  shall
commence  with the last  Business  Day of June,  1997 in the case of a Base Rate
Loan.  After the Revolving  Credit  Termination Date (in the case of a Revolving
Loan) or the Conversion  Date (with respect to accrued  interest coming due as a
result of the conversion),  as applicable,  accrued interest on such Loans shall
be payable on demand.

                   (b)  K-V  hereby  promises  to pay  interest  on  the  unpaid
principal  amount of the Term Loan at a rate per annum  equal to the Fixed  Rate
for the period commencing on the date of such Loan until such Fixed Rate Loan is
paid in full. Accrued interest and principal on the outstanding principal amount
of the Term Loan shall be payable monthly in arrears on the last Business Day of
each calendar  month which payments shall commence with the last Business Day of
the calendar  month in which such Loan is made,  with a final payment of accrued
and unpaid  interest  due on the Term Loan  Maturity  Date.  After the Term Loan
Maturity Date,  accrued  interest and principal on such Loan shall be payable on
demand.

                   (c)  Each  LIBOR  Loan  shall  be  in  a  minimum  amount  of
$1,000,000 or such greater amount which is an integral  multiple of $100,000 and
shall bear interest (computed on the basis of a year of 360 days and actual days
elapsed) on the unpaid principal amount thereof from the date such LIBOR Loan is
effected by conversion or continued  until maturity  (whether by acceleration or
otherwise)  at a rate per annum  equal to the sum of the LIBOR  Margin  plus the
Adjusted  LIBOR Rate,  with such interest  payable in accordance  with Paragraph
4.1(a) above.

                   (d)  If an  Event  of  Default  shall  have  occurred  and be
continuing hereunder,  the Loans shall bear interest from the date of such Event
of Default, payable on demand, at a rate per annum (the "Default Rate") equal to
the sum of two percent (2%) plus the applicable  interest rate from time to time
in effect (computed on the basis of a 360 day year and actual days elapsed).

                                       16


         4.2  Computation  of Interest.  Interest on each Loan shall be computed
for the  actual  number of days  elapsed  on the basis of a  360-day  year.  The
interest rate applicable to each Base Rate Loan shall change simultaneously with
each change in such Base Rate.  Upon  conversion  of less than all the aggregate
principal amount of Base Rate Loans outstanding at any one time to a LIBOR Loan,
interest on the remaining  principal amount of Base Rate Loans shall continue to
bear interest at the Base Rate.

         4.3       Conversion and Reborrowing of Loans.

                   (a)  Provided  that no Event of Default has  occurred  and is
continuing, Base Rate Loans may, subject to Paragraphs 2.3 and 4.1(a) hereof, at
any time be converted  by any  Borrower to LIBOR Loans,  which LIBOR Loans shall
mature  and  become  due and  payable  on the  last day of the  Interest  Period
applicable  thereto.  Provided  that no Event of  Default  has  occurred  and is
continuing,  Borrower shall have the right,  subject to the terms and conditions
of this  Agreement,  to  reborrow  through a new LIBOR Loan in whole or in part,
subject to Paragraph  4.1(c),  any LIBOR Loan from any current  Interest  Period
into a subsequent Interest Period, provided that Borrower shall give Bank notice
of the reborrowing of any such LIBOR Loan as provided in Paragraph 2.3 hereof.

                   (b) In the event that (i) Representative fails to give notice
pursuant to Paragraph 2.3 hereof of the  reborrowing  of any LIBOR Loan or fails
to specify the Interest Period  applicable to such  reborrowing or (ii) an Event
of Default has occurred and is  continuing at the time any such LIBOR Loan is to
be reborrowed hereunder,  then such LIBOR Loan shall be automatically reborrowed
as a Base Rate Loan,  subject to Paragraphs  4.1(d) (in the case of subpart (ii)
of this Paragraph 4.3(b)) and 9.3 hereof if an Event of Default has occurred and
is continuing,  whichever is applicable,  unless the relevant LIBOR Loan is paid
in full on the last day of the then applicable Interest Period.

                   (c)   Notwithstanding   anything   contained  herein  to  the
contrary,  Borrowers may not have outstanding at any one time more than four (4)
LIBOR Loans.

         4.4  Change  of  Law.  Notwithstanding  any  other  provisions  of this
Agreement or the Notes,  if at any time Bank shall  determine in good faith that
any change in  applicable  law or regulation  or in the  interpretation  thereof
makes it unlawful or  impossible  for Bank to effect a conversion of a Base Rate
Loan into a LIBOR Loan or to  continue to  maintain  any LIBOR Loan,  Bank shall
promptly  give  notice  thereof  (together  with an  explanation  of the reasons
therefor) to  Borrowers,  and the  obligation of Bank to effect by conversion or
continue such LIBOR Loan under this  Agreement  shall  terminate  until it is no
longer  unlawful or impossible for Bank to effect by conversion or maintain such
LIBOR Loan.  Upon the receipt of such notice,  Borrowers may elect to either (i)

                                       17


pay or prepay, as the case may be, the outstanding  principal amount of any such
LIBOR Loan,  together  with all interest  accrued  thereon and all other amounts
payable to Bank under this  Agreement,  or (ii) convert the principal  amount of
such affected LIBOR Loan to a Base Rate Loan available hereunder, subject to the
terms and conditions of this Agreement.

         4.5 Unavailability of Deposits or Inability to Ascertain the LIBOR Rate
or Adjusted LIBOR Rate. Notwithstanding any other provision of this Agreement or
the Notes to the contrary,  if prior to the  commencement of any Interest Period
Bank shall  determine in good faith (i) that deposits in the amount of any LIBOR
Loan  scheduled  to be  outstanding  are not  available  to Bank in the relevant
market  or (ii) by  reason  of  circumstances  affecting  the  relevant  market,
adequate and reasonable  means do not exist for  ascertaining  the LIBOR rate or
Adjusted LIBOR Rate,  then Bank shall promptly give notice thereof to Borrowers,
and the  obligation  of Bank to effect by  conversion or continue any such LIBOR
Loan in such amount and for such Interest  Period shall terminate until deposits
in such amount and for the Interest  Period  selected by Borrower shall again be
readily available in the relevant market and adequate and reasonable means exist
for ascertaining the LIBOR rate or Adjusted LIBOR Rate, as the case may be. Upon
the giving of such notice,  Borrowers may elect to either (i) pay or prepay,  as
the case may be,  the  outstanding  principal  amount  of any such  LIBOR  Loan,
together with all interest accrued thereon and all other amounts payable to Bank
under this Agreement or (ii) convert the principal amount of such affected LIBOR
Loan to a Base  Rate  Loan  available  hereunder,  subject  to all the terms and
conditions of this Agreement.

         4.6       Yield Protection, Etc.

                   (a)  Increased  Costs.  If (x)  Regulation  D of the Board of
Governors of the Federal Reserve  System,  or (y) the adoption of any applicable
law, treaty, rule, regulation or guideline, or any change therein, or any change
in the interpretation or administration  thereof by any governmental  authority,
central  bank  or  comparable   agency  charged  with  the   interpretation   or
administration thereof, or compliance by any Bank or its lending branch with any
request  or  directive  (whether  or not  having  the  force of law) of any such
authority, central bank or comparable agency,

                           (i) shall  subject  Bank,  its lending  branch or any
         Loan to any tax, duty, change,  stamp tax, fee, deduction,  withholding
         or other charge in respect of this  Agreement,  any Loan,  the Notes or
         the  obligation  of Bank to make or maintain any Loan,  or shall change
         the  basis of  taxation  of  payments  to Bank of the  principal  of or
         interest on any Loan or any other  amounts due under this  Agreement in
         respect  of any Loan or its  obligation  to make or  maintain  any Loan
         (except  for  changes in the rate of tax on the  overall  net income of
         Bank  imposed  by the  federal,  state or local  jurisdiction  in which
         Bank's principal executive office or its lending branch is located);


                                       18


                           (ii)  shall  impose,  modify or deem  applicable  any
         reserve  (including,  without  limitation,  any reserve  imposed by the
         Board of Governors of the Federal Reserve  System),  special deposit or
         similar requirement against assets of, deposits with or for the account
         of, or credit extended by, Bank; or

                           (iii) shall  impose on Bank any penalty  with respect
         to the foregoing or any other condition  affecting this Agreement,  any
         Loan, the Notes or the obligation of Bank to make or maintain any Loan;

and the result of any of the  foregoing is to increase the cost to (or to impose
a cost on) Bank of making or  maintaining  any Loan,  or to reduce the amount of
any sum received or receivable  by Bank under this  Agreement or under the Notes
with respect  thereto,  then Bank shall notify Borrowers after it receives final
notice of any of the foregoing and, within  forty-five (45) days after demand by
Bank (which demand shall be accompanied  by a statement  setting forth the basis
of such demand), Borrowers shall pay directly to Bank for such additional amount
or amounts as will compensate Bank for such increased cost or such reduction.

                   (b) Capital Adequacy.  If, after the date hereof,  either (i)
the introduction of or any change in or change in the  interpretation of any law
or regulation or (ii)  compliance by Bank with any 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 Bank or any corporation  controlling Bank and Bank determines that
the  amount of such  capital  is  increased  solely by or solely  based upon the
existence of Bank's  commitment to lend hereunder and other  commitments of this
type,  then, upon demand by Bank,  Borrower shall  immediately pay to Bank, from
time to time as specified by Bank,  additional  amounts sufficient to compensate
Bank in the light of such  circumstances,  to the  extent  that Bank  reasonably
determines  such  increase in capital to be allocable to the existence of Bank's
commitment to lend hereunder.

         4.7 Funding Indemnity.  In the event Bank shall incur any loss, cost or
expense (including, without limitation, any loss of profit and any loss, cost or
expense  incurred by reason of the liquidation or  re-employment  of deposits or
other funds acquired by Bank to fund or maintain any LIBOR Loan or the relending
or  reinvesting of such deposits or amounts paid or prepaid to Bank) as a result
of:

                   (a) any payment of a LIBOR Loan on a date other than the last
day of the then applicable Interest Period;

                   (b) any failure by any  Borrower to effect by  conversion  or
continue any LIBOR Loan on the date  specified  in the notice given  pursuant to
Paragraph 2.3 hereof;

                                       19

                   (c) any  failure  by any  Borrower  to make  any  payment  of
principal or interest when due on any LIBOR Loan, whether at stated maturity, by
acceleration or otherwise; or

                   (d) the occurrence of any Event of Default;

then,  upon the demand by Bank,  Borrowers shall pay to Bank such amount as will
reimburse  Bank for such loss,  cost or expense.  If Bank makes such a claim for
compensation  under  this  Paragraph  4.7,  Bank  shall  provide  to  Borrower a
certificate setting forth the amount of such loss, cost or expense in reasonable
detail.

         4.8  Discretion  of Bank as to Manner of Funding.  Notwithstanding  any
provision of this Agreement to the contrary other than Paragraph 4.7, Bank shall
be entitled to fund and  maintain its funding of all or any part of the Loans in
any manner it sees fit, it being understood,  however,  that for the purposes of
this  Agreement  all  determinations  hereunder  shall  be made  as if Bank  had
actually  funded and maintained  each LIBOR Loan during each Interest Period for
such LIBOR Loan through the purchase of deposits in the London  Interbank Market
having a maturity  corresponding to such Interest Period and bearing an interest
rate equal to the Adjusted LIBOR Rate for such Interest Period.

         4.9  Interest  Laws.  Notwithstanding  any  provision  to the  contrary
contained in this  Agreement  or the Other  Agreements,  Borrowers  shall not be
required  to pay,  and Bank shall not be  permitted  to  collect,  any amount of
interest in excess of the maximum  amount of interest  permitted by law ("Excess
Interest").  If any Excess  Interest is provided for or determined by a court of
competent  jurisdiction to have been provided for in this Agreement or in any of
the Other  Agreements,  then in such event: (a) the provisions of this Paragraph
shall govern and control; (b) Borrowers shall not be obligated to pay any Excess
Interest;  (c) any Excess  Interest that Bank may have received  hereunder shall
be, at Bank's option, (i) applied as a credit against the outstanding  principal
balance of Borrowers'  Liabilities or accrued and unpaid interest (not to exceed
the maximum amount  permitted by law),  (ii) refunded to the payor  thereof,  or
(iii) any combination of the foregoing;  (d) the interest  rate(s)  provided for
herein shall be  automatically  reduced to the maximum  lawful rate allowed from
time to time under applicable law (the "Maximum  Rate"),  and this Agreement and
the Other  Agreements  shall be deemed  to have been and shall be  reformed  and
modified to reflect such reduction;  and (e) Borrowers shall not have any action
against  Bank for any damages  arising out of the payment or  collection  of any
Excess  Interest.  Notwithstanding  the  foregoing,  if for any  period  of time
interest on any Borrowers'  Liabilities is calculated at the Maximum Rate rather
than the applicable  rate under this  Agreement,  and thereafter such applicable
rate becomes less than the Maximum  Rate,  the rate of interest  payable on such
Borrowers'  Liabilities  shall  remain at the Maximum Rate until Bank shall have

                                       20


received  the amount of  interest  which Bank would have  received  during  such
period on such Borrowers'  Liabilities had the rate of interest not been limited
to the Maximum Rate during such period.

         4.10 Letter of Credit Fees. As additional consideration for issuing, or
causing to be issued,  Letters of Credit for  Borrowers  at  Borrowers'  request
pursuant to Paragraph 2.4 hereof, Borrower agrees to pay fees in respect to each
Letter of Credit so  issued.  Said fees  shall be payable on the date which such
Letter of Credit is issued and (a) for  "standby"  Letters of Credit shall be in
an amount  equal to one percent  (1.0%) per annum of the amount of the Letter of
Credit multiplied by a fraction, the numerator of which is the number of days in
the term of the applicable Letter of Credit and the denominator of which is 360,
payable quarterly in advance, and (b) for "trade" or other Letters of Credit, in
accordance  with Bank's  published fee schedule  then in effect.  In the event a
Letter of Credit is renewed or extended, a fee calculated in the manner provided
above  shall be  payable  for any such  renewal  or  extended  period.  Further,
Borrowers shall pay and/or  reimburse Bank for all fees and charges paid by Bank
on account of any Letter of Credit,  and  Borrowers  shall pay to Bank its usual
and  customary  charges in respect to the  issuance,  or renewal,  of Letters of
Credit.

                             5. LOANS: GENERAL TERMS

         5.1 Payments to Bank. That portion of Borrowers' Liabilities consisting
of: (a)  principal  payable  on  account of the Loans made by Bank to  Borrowers
pursuant to this Agreement shall be payable by Borrowers to Bank (i) as provided
in the Revolving Note or any Letter of Credit in respect of the Revolving  Loans
and (ii) as  provided  in the Term Note in respect of the Term Loan;  (b) costs,
fees and  expenses  payable  pursuant  to this  Agreement  shall be  payable  by
Borrowers  to Bank on demand  (except  the  Unused  Portion  Fee which  shall be
payable as described in Paragraph 5.10 below);  (c) interest payable pursuant to
this  Agreement  shall be payable by  Borrowers to Bank as provided in Paragraph
4.1; and (d) the balance of Borrowers' Liabilities,  if any, shall be payable by
Borrowers to Bank as and when provided in this Agreement.

         5.2  Automatic  Debit.  In order to cause timely  payment to be made to
Bank,  for the account of Bank, of all  Borrowers'  Liabilities as and when due,
Borrowers  hereby  authorize  and direct Bank,  at Bank's  option,  to debit the
amount  of such  Borrowers'  Liabilities  to any  ordinary  deposit  account  of
Borrowers  (including,  without limitation,  by increasing the principal balance
due under the Revolving Loan).

         5.3 Application of Payment.  Each Borrower shall, at the time of making
each  payment  under this  Agreement  or any Note  (whether by account  debit or
otherwise),  specify  to Bank the Loan or other  amounts  payable  by  Borrowers
hereunder to which such payment is to be applied (and in the event that it fails
to so specify,  or if an Event of Default has occurred and is  continuing,  Bank
may  distribute  such  payment  in such  manner  as  Bank  may  determine  to be
appropriate.

                                       21


         5.4       Reserved.

         5.5 Conditions Precedent Events. Each Loan made by Bank to Borrowers at
the request of  Borrowers  pursuant to this  Agreement  or the Other  Agreements
shall in any event be subject to the following conditions  precedent:  (a) there
shall not then exist an Event of Default (as  hereinafter  defined) or any event
or  condition  which with  notice,  lapse of time and/or the making of such Loan
would constitute an Event of Default;  (b) the  representations,  warranties and
covenants of each Borrower contained in this Agreement shall be true and correct
as of the date of such Loan except for those made as of a  particular  date with
the same  effect as  though  made on such  date;  (c) all of the  covenants  and
agreements of each Borrower in this  Agreement,  and all of the  requirements of
this Agreement with respect to such Loan, shall have been complied with; and (d)
there shall not have occurred,  since the date of this  Agreement,  any material
adverse change in the financial condition,  results of operations or business of
any  Borrower.  Each  borrowing  by any  Borrower  hereunder  shall be  deemed a
representation and warranty by such Borrower that the foregoing  conditions have
been fulfilled as of the date of such  borrowing.  Bank shall have received upon
request a certificate signed by an Authorized Officer of such Borrower dated the
date of such requested Loan certifying  satisfaction of the conditions specified
in clauses (a)-(d) of this Paragraph 5.5.

         5.6 Offset.  Each  Borrower  agrees  that,  in addition to (and without
limitation  of) any right of set-off,  bankers'  lien or  counterclaim  Bank may
otherwise have, Bank shall be entitled,  at its option,  to offset balances held
by it for  account of such  Borrower  at any of its  offices,  in United  States
Dollars or in any other currency, against any principal of or interest on any of
its Loans, or any other amount payable to Bank hereunder, which is not paid when
due (regardless of whether such balances are then due to such Borrower).

         5.7 Credit  Termination  Date;  Continuance of  Obligations,  Etc. This
Agreement,  Bank's  obligation to loan monies to Borrowers,  and each Borrower's
ability to borrow monies from Bank shall be in effect until the Revolving Credit
Termination Date or Term Loan Termination  Date, as applicable.  Notwithstanding
the foregoing and until such date when Borrowers'  Liabilities  shall be paid in
full, each Borrower's obligations hereunder and under the Other Agreements shall
continue,  interest shall  continue to be paid in accordance  with the foregoing
and Bank shall retain all of its rights and remedies under this Agreement.

         5.8 Loan  Evidence.  Loans made by Bank to  Borrowers  pursuant to this
Agreement may or may not (at Bank's sole and absolute  discretion)  be evidenced
by notes or other  instruments  issued or made by Borrowers to Bank.  Where such
loans are not so evidenced, such loans shall be evidenced solely by entries upon
the ledgers,  books, records and/or computer records of Bank maintained for that

                                       22





purpose, which entries shall be rebuttably presumptive evidence of such loans in
the absence of manifest error.

         5.9  Over-Advances.  If, at any time and for any reason,  the aggregate
amount  of  Borrowers'  Liabilities  outstanding  hereunder  in  respect  of the
Revolving  Loans exceeds the Revolving  Credit  Commitment (an  "Over-Advance"),
then  Borrowers  shall  immediately  pay to Bank,  in cash,  the  amount of such
Over-Advance.  If such Over-Advance  remains outstanding for more than three (3)
Business Days until such  Over-Advance  is so repaid to Bank, the amount of such
Over-Advance shall bear interest at the applicable Default Rate.

         5.10 Unused  Portion Fee. To compensate  Bank for the cost of reserving
funds to be made available to Borrowers  under this  Agreement,  Borrowers shall
pay to Bank, on the last day of each calendar  quarter an unused  revolving line
fee (the "Unused  Portion  Fee") equal to the sum of the daily  amounts by which
the  maximum  aggregate  principal  amount of the  Revolving  Credit  Commitment
exceeds the actual  principal  amount of  Revolving  Loans made  hereunder.  The
Unused Portion Fee is calculated  for each  applicable day of such quarter in an
amount  equal to the excess of the  maximum  aggregate  principal  amount of the
Revolving  Credit  Commitment  over  the  principal  amount  of all  outstanding
advances under the Revolving Loans on such day,  multiplied by one-eighth of one
percent  (1/8%) and divided by three hundred  sixty (360).  All fees and charges
imposed on Borrowers pursuant to this Agreement  including,  without limitation,
the  Unused  Portion  Fee  accrued  through  the date of  termination,  shall be
nonrefundable  to Borrowers,  notwithstanding  any prepayment and termination by
Borrowers of this Agreement.

         5.11 Prepayment.  (a) Term Loan Prepayment. K-V may, from time to time,
prepay  the Loan  evidenced  by the  Term  Note in whole or in part and the same
shall pay,  subject to Section 5.7  hereof,  the  Make-Whole  Amount (as defined
below)  plus a  prepayment  fee  equal  to (i) two  percent  (2%) of the  unpaid
principal  balance of the Term Loan prior to the first (1st)  anniversary of the
Closing Date, and (ii) one percent (1%) of the unpaid  principal  balance of the
Term Loan prior to the second (2nd)  anniversary of the Closing Date;  provided,
however,  that, prior to the occurrence of an Event of Default,  such prepayment
fee shall not be due and payable upon prepayment under  circumstances where Bank
has been requested by Borrowers to renew the Revolving Credit  Commitment at the
expiration  or maturity  thereof and either (a) Bank has refused to do so or (b)
Bank has offered  such renewal upon terms  materially  different  and adverse to
Borrowers. For the purposes hereof, the "Make- Whole Amount" shall be the amount
calculated as follows:

                           (i) There shall first be  determined,  as of the date
fixed for prepayment (the "Prepayment  Date"),  the amount, if any, by which (A)
the Fixed  Rate  exceeds  (B) the yield to  maturity  percentage  for the United
States Treasury Note maturing June,  2002 (the "Treasury  Note") as published in


                                       23


The Wall Street Journal on the fifth business day preceding the Prepayment  Date
plus Two Hundred and Twenty-Five basis points (2.25%) (the "Current Yield").  If
(A) publication of The Wall Street Journal is  discontinued,  or (B) publication
of the Treasury Note in The Wall Street  Journal is  discontinued,  Bank, in its
sole  discretion,  shall  designate  another  daily  financial  or  governmental
publication of national circulation to be used to determine the Current Yield;

                           (ii) The difference calculated pursuant to clause (i)
above shall be  multiplied by the  outstanding  principal  balance  hereof as of
Prepayment Date;

                           (iii) The product calculated  pursuant to clause (ii)
above shall be multiplied by the quotient,  rounded to the nearest one-hundredth
of one percent,  obtained by dividing (A) the number of days from and  including
the Prepayment Date to and including the Maturity Date, by (B) 365; and

                           (iv) The sum  calculated  pursuant  to  clause  (iii)
above shall be discounted at the annual rate of the Current Yield to the present
value thereof as of the Prepayment  Date, on the assumption  that said sum would
be received in equal monthly  installments  on each monthly  anniversary  of the
Prepayment Date prior to the Maturity Date,  with the final such  installment to
be deemed  received on the Maturity Date;  provided that Borrowers  shall not be
entitled in any event to a credit  against,  or a  reduction  of, the Debt being
prepaid if the Current Yield exceeds the Fixed Rate or for any other reason.

                   (b) Revolving  Loan  Prepayment.  The  Revolving  Loan may be
prepaid in full, and the Revolving Credit Commitment  extinguished,  if and only
if the Term  Loan has been paid in full in  accordance  with  Paragraph  5.11(a)
above.

         5.12 Transaction Fee. On or prior to the Closing Date,  Borrowers shall
pay an aggregate fee of $85,000, comprised of a fee of $50,000 in respect of the
Revolving Loan and $35,000 in respect of the Term Loan (the  "Transaction  Fee")
to Bank, of which $25,000 in respect of the Revolving  Loan has been  previously
paid by K-V.

Default,  all costs,  fees and expenses  incurred by Bank, or for which Bank has
become obligated,  in connection with such inspection and/or  verification shall
constitute part of Borrowers'  Liabilities,  payable by each Borrower to Bank on

Collateral consisting of personal property, and the books and records concerning
the  Collateral,  consisting  of books and records with respect to both real and

not remove such books and records and/or the Collateral  therefrom and shall not
keep any of such books and records  and/or the Collateral at any other office or
location  without  the prior  written  consent  of Bank;  and (c) the  addresses
specified on Exhibit 7.4 include and designate  K-V's executive  offices,  chief

         7.5  Constructive  Trust.  Borrowers  shall  receive,  as the  sole and
exclusive property of Bank, and as trustee for Bank, all monies,  checks, notes,
drafts and all other payment for and/or  proceeds of Collateral  which come into
the  possession  or under the  control  of  Borrowers  (or any of its  partners,
officers,  employees,  agents or those  Persons  acting for or in  concert  with

in its sole and absolute discretion, may take control of, in any manner, and may
endorse any Borrower's  name, as appropriate,  to any of the items of payment or
proceeds  described in Paragraph  7.5 above and,  pursuant to the  provisions of
this Agreement, Bank may, in its sole and absolute discretion, apply the same to
and on account of Borrowers'  Liabilities  in respect of the Term Loan.  For the
purposes  of  this  Paragraph,   each  Borrower,   irrevocably,   hereby  makes,
constitutes  and  appoints  Bank (and all  persons  designated  by Bank for that
purpose) as each  Borrower's  true and lawful  attorney and  agent-in-fact  with
power, without notice to any Borrower, to take any such actions.

         7.7 Third  Party  Collateral  Claims.  Bank,  in its sole and  absolute
discretion,  without  waiving or releasing  any Event of Default or  obligation,
liability, or duty of any Borrower under this Agreement or the Other Agreements,
may at any time or times  hereafter,  but shall be under no obligation  to, pay,
acquire and/or accept an assignment of any security interest, lien, encumbrance,
or claim asserted by any Person against the Collateral. All sums paid by Bank in
respect  thereof  and  all  costs,  fees  and  expenses,   including  reasonable

this Agreement against such sales, with respect to any portion of the Collateral
or any item thereof not covered by said authorization.

                  8. REPRESENTATIONS AND WARRANTIES; COVENANTS;
                     INDEMNIFICATION; CONTINUING OBLIGATION

         8.1  Representations  and Warranties of Borrower.  Each Borrower hereby
represents  and  warrants  to Bank as of the date  hereof  and with  respect  to
subsections (a) through (d) and  subsections (f) through (y) below,  the date of
disbursement of each Loan or advance hereunder, as follows:

                   (a) Corporate  Existence and Authority.  Each of K-V, PDI and
ETHEX are  corporations  duly organized,  validly  existing and in good standing
under the laws of the State of Delaware,  New York and  Missouri,  respectively,
and each is duly qualified to do business and is in good standing under the laws
of each state in which the ownership of its properties and the nature and extent
of the activities  transacted by it makes such  qualification  necessary  except
where the failure to be so qualified  could not reasonably be expected to have a
material  adverse  effect on its  performance,  business,  assets,  liabilities,
operations,  properties, financial condition or prospects. Each Borrower has the
requisite  corporate  power and authority to conduct its activities as presently
conducted,  to own its  properties  and to perform  its  obligations  under this
Agreement.

                   (b) Authorization;  No Conflict. The execution,  delivery and
performance by each Borrower of this Agreement and the Other Agreements to which
each is a party are within  each  Borrower's  corporate  powers,  have been duly
authorized  by all  necessary  corporate  action and do not  contravene  (i) any
Borrower's Certificate or Articles of Incorporation or Bylaws or (ii) any law or
any contractual  restriction  binding on or affecting each of K-V, PDI and ETHEX
or their respective properties,  and do not result in or require the creation of
any Lien (except as may be created under this Agreement or the Other Agreements)
upon or with respect to any of its properties.

                   (c) No Approval. No authorization or approval or other action
by, and no notice to or filing with,  any  governmental  authority or regulatory

                                       30


body is  required  for the  due  execution,  delivery  and  performance  by each
Borrower of this  Agreement or any Other  Agreement to which each  Borrower is a
party.

                   (d) Validity and Binding  Nature.  This Agreement is, and the
Other Agreements to which each Borrower is a party when delivered hereunder will
be, legal, valid and binding  obligations of each Borrower,  enforceable against
each  Borrower  in  accordance  with  their  respective  terms,  except  as such
enforcement is limited by bankruptcy,  insolvency,  rehabilitation or moratorium
laws or general principles of equity.

                   (e) Financial  Statements  and  Condition.  The balance sheet
(including  the notes  thereto) of K-V and its  Subsidiaries  on a  consolidated
basis as at March  31,  1997,  and the  related  statements  of  operations  and
stockholders'  equity and  statements of cash flows of K-V and its  consolidated
Subsidiaries  for the fiscal year then ended,  have been audited by BDO Seidman,
LLP and are complete and correct,  in accordance  with GAAP,  and fairly present
the financial  condition of K-V and its Subsidiaries on a consolidated  basis as
at such date and the results of the  operations of Borrower for the period ended
on such date and since March 31, 1997, there has been no material adverse change
in any Borrower's financial condition,  business,  properties or operations. The
interim balance sheet (including the notes thereto) of K- V and its Subsidiaries
on a  consolidated  basis as at April 30, 1997,  and the related  statements  of
operations and stockholders'  equity and statements of cash flows for the period
then ended, are complete and correct and fairly present the financial  condition
of K-V and its Subsidiaries on a consolidated  basis at such date, in accordance
with GAAP (subject to normal year-end audit  adjustments and except as specified
in the notes thereto).  No Borrower has on the date hereof, nor will have on the
date of any Loan or advance  made by Bank  hereunder,  any  material  contingent
obligations,  long-term  leases or material  forward or  long-term  commitments,
which are required to be reflected in the foregoing  statements (and the related
notes thereto) and are not so reflected.

                   (f) Litigation. There is no pending or, to the best knowledge
of each Borrower, threatened action, suit, inquiry, investigation, or proceeding
affecting,  directly or indirectly,  any Borrower before any court, governmental
agency or arbitrator, which, in any case, (i) is reasonably likely to materially
and adversely affect the financial condition or operations of any Borrower, (ii)
seeks to  restrain  or would  otherwise  have a material  adverse  effect on the
transactions  contemplated  herein,  or  (iii)  would  affect  the  validity  or
enforceability of this Agreement or the Other Agreements.

                   (g)  Securities  Transaction.  No  proceeds  of any  Loan  or
advance  made by Bank to any  Borrower  hereunder  will be used to  acquire  any
security  in  any  transaction  which  is  subject  to  Section  13 or 14 of the
Securities Exchange Act of 1934, as amended.

                                       31


                   (h)  Regulation  U. No Borrower is engaged in the business of
extending  credit for the purpose of purchasing or carrying margin stock (within
the  meaning of  Regulation  U issued by the Board of  Governors  of the Federal
Reserve  System),  and no  proceeds  of any Loan or advance  made by Bank to any
Borrower  hereunder  will be used to  purchase  or carry any margin  stock or to
extend  credit to others for the purpose of  purchasing  or carrying  any margin
stock.

                   (i) ERISA Termination Event and Funding. No ERISA Termination
Event  has  occurred  with  respect  to any Plan and all  Plans,  to the  extent
governed by ERISA, meet the minimum funding standards of Section 302 of ERISA.

                   (j) Withdrawal  Liability and Reportable  Events. No Borrower
or any ERISA  Affiliate  has  incurred,  or  expects  to incur,  any  withdrawal
liability under Section 4201 of ERISA to any  Multiemployer  Plan. No Reportable
Event (as  defined in ERISA  Section  4043,  other than a  Reportable  Event not
subject  to the  30-day  reporting  requirement  to the  PBGC  under  applicable
regulations) has occurred with respect to any Plan.

                   (k) Taxes.  Each Borrower has filed all tax returns (Federal,
state and local)  required  to be filed and paid all taxes  shown  thereon to be
due, including interest and penalties,  other than such taxes that a Borrower is
contesting in good faith by appropriate legal proceedings and as to which proper
reserves therefor have been established on the books of each Borrower.

                   (l) Liens.  There are no Liens upon or with respect to any of
the  properties  of any  Borrower  or the  Collateral  or any  right to  receive
revenues of any Borrower or the Collateral other than Permitted Liens.

                   (m)  Conflicts.  No Borrower or any  Subsidiary  thereof is a
party to any indenture, loan or credit agreement or any lease or other agreement
or instrument  (including corporate charters) which is likely to have a material
adverse effect on the ability of any Borrower to perform its  obligations  under
this  Agreement  or the Other  Agreements  or which would  restrict or otherwise
limit the  incurring of the Debt  represented  by this  Agreement  and the Other
Agreements.

                   (n)  Environmental  Matters.  Except as  disclosed on Exhibit

         be  liable  to any  Person as a result  of the  Release  or  threatened

         information  under  Section  104  of  the  Comprehensive  Environmental
         Response,  Compensation,  and  Liability  Act (42  U.S.C.  ss.9604)  or

faith by  appropriate  proceedings  to the extent  adequate  reserves  have been

         constitute an Event of Default,  the statement of an Authorized Officer
         setting  forth details of such Event of Default or event and the action

         and absolute  discretion,  to retain, at Bank's expense, an independent
         professional  consultant  to review any report  relating  to  Hazardous
         Materials  prepared by or for any Borrower and at reasonable  times and
         subject to reasonable  conditions to conduct their own investigation at
         Bank's expense of any Facility  currently  owned,  leased,  operated or
         used by Borrowers or any  Subsidiary,  and each Borrower  agrees to use
         its   respective   best  efforts  to  obtain   permission   for  Bank's
         professional  consultant  to  conduct  its  own  investigation  of  any
         Facility previously owned, leased, operated or used by Borrowers or any

         consultants,  and  contractors  the  right to enter  into or on to,  at
         reasonable times, the Facilities currently owned,  leased,  operated or
         used by  Borrowers  or any  Subsidiary  to  perform  such tests on such
         property as are  reasonably  necessary to conduct such a review  and/or
         investigation.

                           (iii)   Promptly   advise  Bank  in  writing  and  in
         reasonable  detail upon  obtaining  knowledge of (i) any Release of any
         Hazardous  Materials  required to be reported to any federal,  state or

         Environmental  Laws,  (ii)  any and  all  written  communications  with
         respect to  Environmental  Claims or any Release of Hazardous  Material
         required to be reported to any federal,  state or local governmental or
         regulatory agency,  (iii) any remedial action taken by Borrowers or any
         other  person in response to (1) any  Hazardous  Material  on, under or
         about any Facility, the existence of which is reasonably likely to give
         rise to an  Environmental  Claim, or (2) any  Environmental  Claim that
         could have a material  adverse  effect on Borrowers or any  Subsidiary,
         (iv) any  Borrower's  discovery of any  occurrence  or condition on any
         real  property  adjoining or in the vicinity of any Facility that could

                                       39

         cause  such  Facility  or  any  part  thereof  to  be  subject  to  any
         restrictions on the ownership, occupancy,  transferability or use there
         of under any  Environmental  Laws, and (v) any request for  information
         from any governmental  agency indicating that such agency has initiated
         an  investigation  as to  whether  Borrower  or any  Subsidiary  may be
         potentially   responsible  for  a  Release  or  threatened  Release  of
         Hazardous Materials.

                           (iv) Promptly  notify Bank of (i) any  acquisition of
         stock,  assets,  or property by any  Borrower  or any  Subsidiary  that
         reasonably  could be expected to expose such Borrower to, or result in,
         Environmental  Claims that could have a material adverse effect or that
         could be expected to have a material adverse effect on any Governmental
         Authorization then held by any Borrower or any Subsidiary, and (ii) any
         proposed action outside of the normal course of business to be taken by
         any  Borrower  or  any  Subsidiary  to  commence  industrial  or  other
         operations  that could  subject  any  Borrower  or such  Subsidiary  to
         additional laws, rules or regulation,  including,  without  limitation,
         laws, rules and regulations requiring additional  environmental permits
         or licenses.

                           (v)  At its  own  expense,  provide  copies  of  such
         documents or information as Bank may reasonably  request in relation to

         action  in  connection  with  the  presence,  storage,  use,  disposal,
         transportation,   Release  or  threatened   Release  of  any  Hazardous
         Materials  on,  under or about any Facility in order to comply with all
         applicable Environmental Laws and Governmental  Authorizations.  In the
         event any Borrower or any  Subsidiary  undertakes  any remedial  action
         with respect to any Hazardous Material on, under or about any Facility,
         such  Borrower  or such  Subsidiary  shall  conduct and  complete  such
         remedial  action in compliance with all applicable  Environmental  Laws
         and in  accordance  with the  policies,  orders and  directives  of all
         federal, state and local governmental authorities.

                                       41


         provided,  however,  that the amount of Capital Expenditures may exceed
         the  limits  set  forth  above  on a  cumulative  basis  so long as the
         aggregate amount of Capital  Expenditures are (a) made with funds other
         than Loan  proceeds  or other  Funded  Debt and (b) at all times do not
         exceed $7,900,000 plus 75% of Borrower's net income, in accordance with
         GAAP,   for  the  period   from  the  Closing   Date  and   thereafter.
         Notwithstanding  the foregoing,  to the extent that the proceeds of the
         Term Loan are used to purchase the Mortgaged Properties,  the amount of
         such proceeds shall not be included  within the  calculation of Capital
         Expenditures hereunder.

                   (h)     Insurance.

                           (i) At its sole cost and  expense,  keep and maintain
         business  interruption  insurance  and public  liability  and  property
         damage  insurance  relating  to its  business  and  properties  and its
         ownership and use of its assets.  All such policies of insurance  shall
         be in form and with insurers recognized as adequate by prudent business
         persons and all such policies  shall be in amounts as may be reasonably
         satisfactory to Bank. Each Borrower shall deliver to Bank a certificate
         of  insurance,  and  evidence of payment of all  premiums  then due and
         owing for each such  policy on or prior to the date of this  Agreement.
         Such policies shall:  (A) contain a lender's loss payable clause naming
         Bank as loss payee and  additional  insured as its interest may appear;
         and (B) provide that the  insurance  companies  will give Bank at least
         thirty (30) days written  notice  before any such policy or policies of
         insurance shall be altered or canceled.

                           (ii) In the event any  Borrower  at any time or times
         hereafter  shall  fail to obtain or  maintain  any of the  policies  of
         insurance  required  above  or to pay any  premium  in whole or in part
         relating  thereto,   then  Bank,   without  waiving  or  releasing  any
         obligation  or Event of Default by any Borrower  hereunder,  may at any
         time or times  thereafter  (but shall be under no obligation to) obtain
         and maintain  such  policies of insurance and pay such premium and take
         any other action with respect thereto which Bank deems  advisable.  All
         sums so disbursed by Bank,  including  reasonable attorneys fees, court
         costs,  expenses and other charges relating  thereto,  shall be part of
         Borrowers'  Liabilities,  payable  by  Borrowers  to  Bank  on  demand.
         Borrowers authorize Bank, in Bank's sole discretion, to cause such sums
         to be paid by making an advance in the amount thereof to the applicable
         Borrower under the Revolving Loan.

         8.3 Negative Covenants. Prior to the later of the Term Loan Termination
Date or the Revolving Credit  Termination Date and thereafter for so long as any
amount is due or owing to Bank hereunder, unless Bank shall otherwise consent in
writing, no Borrower nor any Subsidiary shall:

maturing within one year) and (iii)  investments  already made as of the Closing
Date  as  set  forth  or as  otherwise  listed  on  Exhibit  8.3(d)  ("Permitted
Investments").

                   (e)  Guaranties.  Guaranty,  endorse or  otherwise in any way
directly,  indirectly  or  contingently  become  liable for the  obligations  or

                   (f)  Stock  and  Dividends.   Redeem,  retire,   purchase  or
otherwise  acquire,  directly or  indirectly,  any common  capital  stock of any

Borrowers'  property  or assets  to any  stockholders  except  Ethex and PDI may
declare and pay dividends to K-V.  Notwithstanding the foregoing, if no Event of

ordinary  course of and pursuant to the  reasonable  requirements  of Borrowers'
businesses and upon fair and reasonable  terms which are fully disclosed to Bank
and are no less  favorable to Borrower  than would obtain in a comparable  arm's
length transaction with a Person not an Affiliate of such Borrower.

         8.4  Maintenance  of  Accounts.  Each  Borrower  agrees to maintain its
primary operational  accounts with Bank and shall maintain an average balance of
collected, available funds in a non-interest bearing demand deposit account with
Bank  (the  "Operating  Account")  in an amount  at least  equal to that  amount
required to  compensate  Bank for its  services  in  maintaining  such  account.
Borrowers  acknowledge that Bank will charge Borrowers  standard service charges
in effect from time to time for various services performed by Bank in connection
with any aspect of the  relationship  between  Borrowers and Bank, and Borrowers
hereby agree that if such service charges exceed the credit to Borrowers arising
from  earnings  attributable  to funds on  deposit  with Bank in the  applicable
Operating Account, such service charge deficiency shall be deducted by Bank from
any Borrower's  Operating  Account,  monthly,  in arrears,  within ten (10) days
following  the end of each  month.  Bank may cause  interest  and other  amounts
payable on the obligations of Borrowers to Bank hereunder to be paid by making a
direct charge to the applicable  Operating  Account in accordance with the terms
hereof.

days  of  filing;  (g) if an  application  is  made  by  any  Borrower  for  the

(f),  (g),  (h),  (i)  or  (l),  in  which  case  Borrowers'  Liabilities  shall
automatically  become due and payable without notice or demand,  and (b) without

                                   10. GENERAL

         10.1 Payment  Application  Date. Any check,  draft,  or similar item of
payment by or for the account of any  Borrower  delivered  to Bank on account of
Borrowers'  Liabilities  shall  be  applied  by Bank on  account  of  Borrowers'
Liabilities  on the date final  settlement  thereof is reflected by  irrevocable
credit to Bank.

         10.2 Statement of Account.  Each statement of account by Bank delivered
to any Borrower relating to Borrowers' Liabilities shall be presumed correct and
accurate,  absent manifest error, and shall constitute an account stated between
Borrowers and Bank unless,  within ninety (90) days after Borrowers'  receipt of
said  statement,  Borrowers  deliver to Bank, by  registered  or certified  mail
addressed to Bank at its Address for Notices  specified on the  signature  pages
hereto,  written  objection  thereto  specifying  the error or  errors,  if any,
contained in any such statement.

         10.3  Manner of  Application;  Waiver of Setoff  Prohibition.  Upon the
occurrence  and during the  continuance  of an Event of Default,  each  Borrower
waives the right to direct the  application  of any and all payments at any time
or times  hereafter  received by Bank on account of Borrowers'  Liabilities  and
Borrower  agrees  that Bank  shall  have the  right,  in its  absolute  and sole
discretion,  to apply and re-apply any and all such payments  toward  Borrowers'
Liabilities in such manner as Bank may deem advisable, notwithstanding any entry
by Bank upon any of its books and  records.  Each  Borrower  further  waives any
right  under or  benefit of any law that  would  restrict  or limit the right or
ability of Bank to obtain payment of Borrowers'  Liabilities,  including any law
that would  restrict or limit Bank in the  exercise of its right to  appropriate
any indebtedness  owing from Bank to Borrower and any deposits or other property
of  Borrower in the  possession  or control of Bank and apply the same toward or
setoff the same against the payment of Borrowers' Liabilities.

         10.4  Survival  of  Representations   and  Warranties.   Each  Borrower
covenants,  warrants  and  represents  to  Bank  that  all  representations  and
warranties  of Borrower  contained in this  Agreement  and the Other  Agreements
shall be true at the time of each Borrower's execution of this Agreement and the
Other  Agreements  and shall  survive the  execution,  delivery  and  acceptance
thereof by the parties  thereto and the  closing of the  transactions  described
therein or related thereto.

                                       46

         10.5      Integration; Amendment; Assignment; Participation.

                   (a) This  Agreement and the Other  Agreements  constitute the
entire agreement and  understanding  between the parties relating to the subject
matter hereof and supersede all prior agreements,  whether oral or written. This
Agreement  and the Other  Agreements  may not be  modified,  altered  or amended
except by an  agreement  in writing  signed by each  Borrower  and Bank,  and no
provision of this  Agreement may be waived except with the consent in writing of
Bank.

                   (b) Bank  shall have the right to assign to one or more banks
or other financial  institutions  all or a portion of its rights and obligations
under this Agreement  (including,  without  limitation,  the Loans and the Other
Agreements).  Upon any such  assignment,  (i) the assignee  shall become a party
hereto and, to the extent of such assignment, have all rights and obligations of
Bank hereunder and under the Other Agreements and (ii) Bank shall, to the extent
of such  assignment,  relinquish its rights and be released from its obligations
hereunder and under the Other Agreements;  provided,  however, in the event Bank
assigns all or a portion of its rights and obligations  hereunder  pursuant to a
transaction in which Bank (including  successors thereto) is not the lead agent,
Borrowers  will not be subject to the  prepayment  fee provided for in Paragraph
5.11 hereof as long as K-V has paid in full all Borrowers'  Liabilities  due and
owing in respect of the Term Loan  within  ninety  (90) days of the date of such
assignment.  Each Borrower  hereby agrees to execute and deliver such documents,
and to take such other actions, as Bank may reasonably request to accomplish the
foregoing.

                   (c) In addition to the  assignments  permitted in  subsection
(b) of this  Paragraph  10.5,  Bank and any assignee  pursuant to subsection (b)
above shall have the right to grant participations to one or more banks or other
financial  institutions  in or to any Loan hereunder (and the Other  Agreements)
without notice to or consent from any Borrower.

         10.6 No  Waiver.  Bank's  failure  at any  time or times  hereafter  to
require strict performance by Borrowers of any provision of this Agreement shall
not waive,  affect or diminish  any right of Bank  thereafter  to demand  strict
compliance  and  performance  therewith.  Any suspension or waiver by Bank of an
Event of Default by Borrowers under this Agreement or the Other Agreements shall
not suspend,  waive or affect any other Event of Default by Borrowers under this
Agreement  or the  Other  Agreements,  whether  the same is prior or  subsequent
thereto  and  whether  of  the  same  or  of  a  different  type.  None  of  the
undertakings,  agreements, warranties, covenants or representations of Borrowers
contained in this  Agreement or the Other  Agreements and no Event of Default by
Borrowers under this Agreement or the Other  Agreements  shall be deemed to have
been  suspended  or waived by Bank  unless  such  suspension  or waiver is by an
instrument  in writing by Bank  specifying  such  suspension or waiver and given
pursuant to the requirements of Paragraph 10.16 hereof.

                                       47

         10.7  Severability.  If any  provision  of this  Agreement or the Other
Agreements  or the  application  thereof to any Person or  circumstance  is held
invalid  or  unenforceable,  the  remainder  of this  Agreement  and  the  Other
Agreements   and  the   application  of  such  provision  to  other  Persons  or
circumstances  will not be affected thereby and the provisions of this Agreement
and the Other Agreements shall be severable in any such instance.

applicable  provision  of this  Agreement,  if any  provision  contained in this
Agreement is in conflict with, or inconsistent  with, any provision in the Other
Agreements, the provision contained in this Agreement shall govern and control.

the contrary in this  Agreement and in the Other  Agreements,  no termination or
cancellation  (regardless  of cause or procedure) of this Agreement or the Other
Agreements  shall in any way affect or impair the powers,  obligations,  duties,
rights and  liabilities  of Borrowers or Bank in any way or respect  relating to
(a) any transaction or event occurring prior to such termination or cancellation
and/or  (b)  any of the  undertakings,  agreements,  covenants,  warranties  and
representations   of  Borrowers   contained  in  this  Agreement  or  the  Other
Agreements.  All  such  undertakings,   agreements,  covenants,  warranties  and
representations shall survive such termination or cancellation.
