ITEM 5.  OTHER MATTERS.

         On January 30, 1998 Vision Twenty-One, Inc. (the "Company") finalized
a five year, $50.0 million bank credit agreement (the "Credit Agreement") with
the Bank of Montreal as agent (the "Agent") for a consortium of banks.  The
Credit Agreement, which matures in January, 2003, provided the Company with a
revolving credit facility component in an aggregate amount of up to $10.0
million and a term loan component in an aggregate amount of up to $40.0
million.  The Credit Agreement is secured by a pledge of the stock of
substantially all of the Company's subsidiaries and the assets of the Company
and certain of its subsidiaries and is guaranteed by certain of the Company's
subsidiaries.  The Credit Agreement contains negative and affirmative covenants
and agreements which place restrictions on the Company regarding disposition of
assets, capital expenditures, additional indebtedness, permitted liens and
payment of dividends, as well as requiring the maintenance of certain financial
ratios.  The interest rate on the Credit Agreement is, at the option of the
Company, either (i) the London InterBank Offered Rate plus an applicable margin
rate, (ii) the greater of (a) the Agent's prime commercial rate or (b) the
"federal funds" rate plus 0.5%, or (iii) a fixed rate loan as determined by the
Agent at each time of borrowing.  The Company used approximately $26.0 million
of the available proceeds under the Credit Agreement at the closing to repay
the outstanding balance under the Company's previous credit facility with
Prudential Securities Credit Corporation.  The Company currently has a balance
available of approximately $24 million under the Credit Agreement which it
expects will be utilized for acquisitions and for working capital and general
corporate purposes.

                 On February 2, 1998, the Company issued a press release
announcing the Credit Agreement, a copy of which is filed herewith as Exhibit
99.

                                CREDIT AGREEMENT


To each of the Banks signatory hereto

Ladies and Gentlemen:

         The undersigned, Vision Twenty-One, Inc., a Florida corporation (the
"Borrower"), applies to you for your several commitments, subject to the terms
and conditions hereof and on the basis of the representations and warranties
hereinafter set forth, to extend credit to the Borrower, all as more fully
hereinafter set forth.  Each of you is hereinafter referred to as a "Bank," all
of you are hereinafter referred to collectively as the "Banks," and Bank of
Montreal in its capacity as agent for the Banks hereunder is hereinafter
referred to as the "Agent."

SECTION 1.             THE CREDIT FACILITIES.

           Section 1.1.     Revolving Credit Commitments.  Subject to the terms
and conditions hereof, each Bank, by its acceptance hereof, severally agrees to
make a loan or loans (individually a "Revolving Loan" and collectively the
"Revolving Loans") to the Borrower from time to time on a revolving basis up to
the amount of such Bank's revolving credit commitment set forth on the
applicable signature page hereof or pursuant to Section 12.12 hereof (its
"Revolving Credit Commitment" and, cumulatively for all the Banks, the
"Revolving Credit Commitments"), subject to any reductions thereof pursuant to
the terms hereof, before the Revolving Credit Termination Date.  The sum of the
aggregate principal amount of Revolving Loans and of L/C Obligations at any
time outstanding shall not exceed the Revolving Credit Commitments in effect at
such time.  Each Borrowing of Revolving Loans shall be made ratably from the
Banks in proportion to their respective Revolver Percentages.  As provided in
Section 1.6(a) hereof, the Borrower may elect that each Borrowing of Revolving
Loans be either Base Rate Loans or Eurodollar Loans.  Revolving Loans may be
repaid and the principal amount thereof reborrowed before the Revolving Credit
Termination Date, subject to the terms and conditions hereof.

           Section 1.2.     Letters of Credit.  (a) General Terms.  Subject to
the terms and conditions hereof, as part of the Revolving Credit, the Agent
shall issue standby letters of credit (each a "Letter of Credit") for the
Borrower's account in an aggregate undrawn face amount up to the amount of the
L/C Commitment, provided that the aggregate L/C Obligations at any time
outstanding shall not exceed the difference between the Revolving Credit
Commitments in effect at such time and the aggregate principal amount of
Revolving Loans then outstanding.  Each Letter of Credit shall be issued by the
Agent, but each Bank shall be obligated to reimburse the Agent for such Bank's
Revolver Percentage of the amount of each drawing thereunder and, accordingly,
each Letter of Credit shall constitute usage of the Revolving Credit Commitment
of each Bank pro rata in accordance with its Revolver Percentage.

          (b)    Applications.  At any time before the Revolving Credit
Termination Date, the Agent shall, at the request of the Borrower, issue one or
more Letters of Credit, in a form 



<PAGE>   7

satisfactory to the Agent, with expiration dates no later than the earlier of 12
months from the date of issuance (or be cancelable not later than 12 months from
the date of issuance and each renewal) or Revolving Credit Termination Date, in
an aggregate face amount as set forth above, upon the receipt of an application
duly executed by the Borrower for the relevant Letter of Credit in the form then
customarily prescribed by the Agent for the Letter of Credit requested (each an
"Application").  Notwithstanding anything contained in any Application to the
contrary:  (i) the Borrower shall pay fees in connection with each Letter of
Credit as set forth in Section 2.1 hereof, (ii) except as otherwise provided in
Section 1.9 hereof, before the occurrence of a Default or an Event of Default,
the Agent will not call for the funding by the Borrower of any amount under a
Letter of Credit before being presented with a drawing thereunder, and (iii) if
the Agent is not timely reimbursed for the amount of any drawing under a Letter
of Credit on the date such drawing is paid, the Borrower's obligation to
reimburse the Agent for the amount of such drawing shall bear interest (which
the Borrower hereby promises to pay) from and after the date such drawing is
paid at a rate per annum equal to the sum of 2% plus the Applicable Margin plus
the Base Rate from time to time in effect.  If the Agent issues any Letter of
Credit with an expiration date that is automatically extended unless the Agent
gives notice that the expiration date will not so extend beyond its then
scheduled expiration date, the Agent will give such notice of non-renewal before
the time necessary to prevent such automatic extension if before such required
notice date:  (i) the expiration date of such Letter of Credit if so extended
would be after the Revolving Credit Termination Date, (ii) the Revolving Credit
Commitments have been terminated, or (iii) a Default or an Event of Default
exists and the Required Banks have given the Agent instructions not to so permit
the extension of the expiration date of such Letter of Credit.  The Agent agrees
to issue amendments to the Letter(s) of Credit increasing the amount, or
extending the expiration date, thereof at the request of the Borrower subject to
the conditions of Section 7.2 hereof and the other terms of this Section 1.2.

          (c)    The Reimbursement Obligations.  Subject to Section 1.2(b)
hereof, the obligation of the Borrower to reimburse the Agent for all drawings
under a Letter of Credit (a "Reimbursement Obligation") shall be governed by
the Application related to such Letter of Credit, except that reimbursement
shall be made by no later than 12:00 Noon (Chicago time) on the date when each
drawing is paid in immediately available funds at the Agent's principal office
in Chicago, Illinois.  If the Borrower does not make any such reimbursement
payment on the date due and the Participating Banks fund their participations
therein in the manner set forth in Section 1.2(d) below, then all payments
thereafter received by the Agent in discharge of any of the relevant
Reimbursement Obligations shall be distributed in accordance with Section
1.2(d) below.

          (d)    The Participating Interests.  Each Bank (other than the Bank
then acting as Agent in issuing Letters of Credit), by its acceptance hereof,
severally agrees to purchase from the Agent, and the Agent hereby agrees to
sell to each such Bank (a "Participating Bank"), an undivided percentage
participating interest (a "Participating Interest"), to the extent of its
Revolver Percentage, in each Letter of Credit issued by, and each Reimbursement
Obligation owed to, the Agent.  Upon any failure by the Borrower to pay any
Reimbursement Obligation at the time required on the date the related drawing
is paid, as set forth in Section 1.2(c) above, or if the Agent is required at
any time to return to the Borrower or to a trustee, receiver, 



                                     -2-

<PAGE>   8

liquidator, custodian, or other Person any portion of any payment of any
Reimbursement Obligation, each Participating Bank shall, not later than the
Business Day it receives a certificate in the form of Exhibit A hereto from the
Agent to such effect, if such certificate is received before 1:00 p.m. (Chicago
time), or not later than 1:00 p.m. (Chicago time) the following Business Day, if
such certificate is received after such time, pay to the Agent an amount equal
to such Participating Bank's Revolver Percentage of such unpaid or recaptured
Reimbursement Obligation together with interest on such amount accrued from the
date the related payment was made by the Agent to the date of such payment by
such Participating Bank at a rate per annum equal to: (i) from the date the
related payment was made by the Agent to the date 2 Business Days after payment
by such Participating Bank is due hereunder, the Federal Funds Rate for each
such day and (ii) from the date 2 Business Days after the date such payment is
due from such Participating Bank to the date such payment is made by such
Participating Bank, the Base Rate in effect for each such day.  Each such
Participating Bank shall thereafter be entitled to receive its Revolver
Percentage of each payment received in respect of the relevant Reimbursement
Obligation and of interest paid thereon, with the Agent retaining its Revolver
Percentage as a Bank hereunder.

         The several obligations of the Participating Banks to the Agent under
this Section 1.2 shall be absolute, irrevocable, and unconditional under any
and all circumstances whatsoever and shall not be subject to any set-off,
counterclaim or defense to payment which any Participating Bank may have or
have had against the Borrower, the Agent, any other Bank, or any other Person
whatsoever.  Without limiting the generality of the foregoing, such obligations
shall not be affected by any Default or Event of Default or by any reduction or
termination of any Commitment of any Bank, and each payment by a Participating
Bank under this Section 1.2 shall be made without any offset, abatement,
withholding, or reduction whatsoever.  The Agent shall be entitled to offset
amounts received for the account of a Bank under this Agreement against unpaid
amounts due from such Bank to the Agent hereunder (whether as fundings of
participations, indemnities, or otherwise), but shall not be entitled to offset
against amounts owed to the Agent by any Bank arising outside of this
Agreement.

          (e)    Indemnification.  The Participating Banks shall, to the extent
of their respective Revolver Percentages, indemnify the Agent (to the extent
not reimbursed by the Borrower) against any cost, expense (including reasonable
counsel fees and disbursements), claim, demand, action, loss, or liability
(except such as result from the Agent's gross negligence or willful misconduct)
that the Agent may suffer or incur in connection with any Letter of Credit.
The obligations of the Participating Banks under this Section 1.2(e) and all
other parts of this Section 1.2 shall survive termination of this Agreement and
of all Applications, Letters of Credit, and all drafts and other documents
presented in connection with drawings thereunder.

           Section 1.3.     Term Credit Commitments.  Subject to the terms and
conditions hereof, each Bank, by its acceptance hereof, severally agrees to
make one or more loans (individually a "Term Loan" and collectively the "Term
Loans") to the Borrower from time to time in the aggregate amount of such
Bank's term credit commitment as set forth on the applicable signature page
hereof or pursuant to Section 12.12 hereof (its "Term Credit Commitment" and,
cumulatively for all the Banks, the "Term Credit Commitments"), subject to any
reductions thereof pursuant to the terms hereof, before the Term Credit
Termination Date.

their respective Term Percentages.  Each Borrowing of Term Loans shall be used
solely for the purpose of (a) retiring indebtedness owing to Prudential
Securities Credit Corporation, (b) financing acquisitions permitted under
Section 8.15(k) hereof, and (c) financing the redemption of certain equity
securities of the Borrower pursuant to Section 8.18(b) hereof. Each Borrowing of
Term Loans shall be in an amount of $1,000,000 or such greater amount which is
an integral multiple of $100,000.  As provided in Section 1.6(a) hereof, the
Borrower may elect that each Borrowing of Term Loans be either Base Rate Loans,
Eurodollar Loans, or Fixed Rate Loans.  The principal amount of each Term Loan
made by a Bank to the Borrower shall permanently reduce the amount available to
the Borrower under such Bank's Term Credit Commitment, and no amount repaid or
prepaid on any Term Loan may be borrowed again.

           Section 1.4.     Applicable Interest Rates.  (a) Base Rate Loans.
Each Base Rate Loan made or maintained by a Bank shall bear interest during
each Interest Period it is outstanding on the unpaid principal amount thereof
from the date such Loan is advanced, continued or created by conversion from a
Eurodollar Loan until maturity (whether by acceleration or otherwise) at a rate
per annum equal to the sum of the Applicable Margin plus the Base Rate from
time to time in effect, payable on the last day of its Interest Period and at
maturity (whether by acceleration or otherwise).

          "Base Rate" means for any day the greater of:  (i) the rate of
interest announced by the Agent from time to time as its prime commercial rate,
or equivalent, for U.S. Dollar loans to borrowers located in the United States
with any change in the Base Rate resulting from a change in said prime
commercial rate to be effective as of the date of the relevant change in said
prime commercial rate (it being acknowledged and agreed that such rate may not
be the Agent's best or lowest rate (computed on the basis of a year of 365 or
366 days, as the case may be, and actual days elapsed); and (ii) the sum of (x)
the rate for that day set forth opposite the caption "Federal Fund (Effective)"
in the daily statistical release designated as "Composite 3:30 P.M. Quotations
for U.S. Government Securities," or any successor publication, published by the
Federal Reserve Bank of New York or, if such publication shall be suspended or
terminated, the rate determined by the Agent (based on quotations received from
two or more Federal funds dealers of recognized standing) to be the prevailing
rate per annum (rounded upward, if necessary, to the nearest 1/100 of 1%) at
approximately 10:00 a.m. (Chicago time) (or as soon thereafter as is
practicable) on such day for the purchase at face value of overnight Federal
funds in an amount approximately equal to the principal amount owed to the
Agent for which such rate is being determined, plus (y) 1/2 of 1% (computed on
the basis of a year of 360 days and actual days elapsed).
 
         (b)    Eurodollar Loans.  Each Eurodollar Loan made or maintained by
a Bank shall bear interest during each Interest Period it is outstanding
(computed on the basis of a year of 360 days and actual days elapsed) on the
unpaid principal amount thereof from the date such Loan is advanced, continued,
or created by conversion from a Base Rate Loan until maturity (whether by
acceleration or otherwise) at a rate per annum equal to the sum of the
Applicable Margin plus the Adjusted LIBOR applicable for such Interest Period,
payable on the last day of the Interest Period and at maturity (whether by
acceleration or otherwise), and, if the 



                                     -4-
<PAGE>   10

applicable Interest Period is longer than three months, on each day occurring
every three months after the commencement of such Interest Period.

         "Adjusted LIBOR" means, for any Borrowing of Eurodollar Loans, a rate
per annum determined in accordance with the following formula:

         Adjusted LIBOR =       LIBOR             
                           --------------------------------
                           1 - Eurodollar Reserve Percentage

         "LIBOR" means, for an Interest Period for a Borrowing of Eurodollar
Loans, (a) the LIBOR Index Rate for such Interest Period, if such rate is
available, and (b) if the LIBOR Index Rate cannot be determined, the arithmetic
average of the rates of interest per annum (rounded upwards, if necessary, to
the nearest 1/100 of 1%) at which deposits in U.S.  Dollars in immediately
available funds are offered to the Agent at 11:00 a.m. (London, England time) 2
Business Days before the beginning of such Interest Period by 3 or more major
banks in the interbank eurodollar market selected by the Agent for delivery on
the first day of and for a period equal to such Interest Period and in an
amount equal or comparable to the principal amount of the Eurodollar Loan
scheduled to be made by the Agent as part of such Borrowing.

         "LIBOR Index Rate" means, for any Interest Period, the rate per annum
(rounded upwards, if necessary, to the next higher one hundred-thousandth of a
percentage point) for deposits in U.S. Dollars for a period equal to such
Interest Period, which appears on the Telerate Page 3750 as of 11:00 a.m.
(London, England time) on the day 2 Business Days before the commencement of
such Interest Period.

         "Telerate Page 3750" means the display designated as "Page 3750" on
the Telerate Service (or such other page as may replace Page 3750 on that
service or such other service as may be nominated by the British Bankers'
Association as the information vendor for the purpose of displaying British
Bankers' Association Interest Settlement Rates for U.S. Dollar deposits).

         "Eurodollar Reserve Percentage" means, for any Borrowing of Eurodollar
Loans, the daily average for the applicable Interest Period of the maximum
rate, expressed as a decimal, at which reserves (including, without limitation,
any supplemental, marginal, and emergency reserves) are imposed during such
Interest Period by the Board of Governors of the Federal Reserve System (or any
successor) on "eurocurrency liabilities", as defined in such Board's Regulation
D (or in respect of any other category of liabilities that includes deposits by
reference to which the interest rate on Eurodollar Loans is determined or any
category of extensions of credit or other assets that include loans by
non-United States offices of any Bank to United States residents), subject to
any amendments of such reserve requirement by such Board or its successor,
taking into account any transitional adjustments thereto.  For purposes of this
definition, the Eurodollar Loans shall be deemed to be "eurocurrency
liabilities" as defined in Regulation D without benefit or credit for any
prorations, exemptions or offsets under Regulation D.

          (c)    Fixed Rate Loans.  Each Fixed Rate Loan made or maintained by
a Bank shall bear interest during each Interest Period it is outstanding
(computed on the basis of a year of 360 days for the actual days elapsed) on
the unpaid principal amount thereof from the date such Loan is advanced until
maturity (whether by acceleration or otherwise) at a rate per annum equal to
the sum of the Applicable Margin with respect to Eurodollar Loans as from time
to time in effect plus the Adjusted Fixed Rate applicable to the relevant
Borrowing of Term Loans, payable on the last day of each March, June,
September, and December occurring after the relevant Borrowing of Fixed Rate
Loans is advanced and at maturity (whether by acceleration or otherwise).
Fixed Rate Loans shall only be available for Borrowings of Term Loans.  In the
event the Borrower elects that a Borrowing of Term Loans constitute Fixed Rate
Loans, such election shall be irrevocable and remain in effect with respect to
such Borrowing of Term Loans from the date such Loans are advanced through the
Term Credit Final Maturity Date.

         "Adjusted Fixed Rate" means, for any Borrowing of Fixed Rate Loans, a
rate per annum determined in accordance with the following formula:

         Adjusted Fixed Rate   =                 Fixed Rate 
                                      ----------------------------------
                                      100% - Eurodollar Reserve Percentage

         "Floating Rate Payor" means Bank of Montreal, in its capacity as a
payment obligor under Section 1.4(d) below.  

         "Fixed Rate" means, with respect to a Borrowing of Fixed Rate Loans 
advanced on the same day, the rate per annum quoted to the Borrower by the
Floating Rate Payor on the date on which such Borrowing is to be advanced, it
being acknowledged and agreed that the Fixed Rate shall be established at the
time of each Borrowing of Term Loans by the Floating Rate Payor in its sole
discretion.

          (d)    Floating Rate Payor Obligation.  Subject to receipt by the
Agent of payment in full of interest due by the Borrower with respect to each
Borrowing of Fixed Rate Loans, the Agent will remit to the Floating Rate Payor
the interest so paid by the Borrower and the Floating Rate Payor shall pay to
the Agent for distribution to the Banks ratably an amount equal to interest
which would have accrued on such Borrowing for the relevant Interest Period at
a rate per annum equal to the sum of the Applicable Margin with respect to
Eurodollar Loans in effect during such period plus the Adjusted LIBOR (as
determined by the Floating Rate Payor on the first day of the relevant calendar
quarter and determined as if the relevant Interest Period was 3 months,
provided during the first three months following the date hereof such rate
shall be determined on the first day of each month and determined as if the
relevant Interest Period was 1 month).  In the event any such Fixed Rate Loans
bear interest at the default rate provided for in Section 1.10(c) hereof, the
Banks shall also be entitled to receive from the Floating Rate Payor their pro
rata share thereof, based on their Term Percentages of the relevant Borrowing
of Term Loans, to the extent paid by the Borrower.  In the event interest on
any such Fixed Rate Loan is not paid, either in whole or in part, by the
Borrower, then the Floating Rate Payor shall be obligated to pay to the Agent
for distribution to the Banks an amount determined by multiplying the amounts
due the Banks as set forth above 




                                     -6-

<PAGE>   12

times a fraction, the numerator of which is the amount of interest actually paid
by the Borrower to the Agent and the denominator of which is the amount of
interest due from Borrower with respect to such Fixed Rate Loans.

          (e)    Rate Determinations.  The Agent shall determine each interest
rate applicable to the Loans (other than Fixed Rate Loans) and the
Reimbursement Obligations hereunder, and its determination thereof shall be
conclusive and binding except in the case of manifest error.  The Floating Rate
Payor shall determine each interest rate applicable to the Fixed Rate Loans,
and its determination thereof shall be conclusive and binding except in the
case of manifest error.

           Section 1.5.     Minimum Borrowing Amounts.  Each Borrowing of Base
Rate Loans advanced under a Credit shall be in an amount not less than
$1,000,000.  Each Borrowing of Eurodollar Loans advanced, continued, or
converted under a Credit shall be in an amount equal to $1,000,000 or such
greater amount which is an integral multiple of $100,000.  Each Borrowing of
Fixed Rate Loans advanced under the Term Credit shall be in an amount equal to
$1,000,000 or such greater amount which is an integral multiple of $100,000.

           Section 1.6.     Manner of Borrowing Loans and Designating
Applicable Interest Rates.  (a) Notice to the Agent.  The Borrower shall give
notice to the Agent by no later than 10:00 a.m. (Chicago time):  (i) at least 3
Business Days before the date on which the Borrower requests the Banks to
advance a Borrowing of Eurodollar Loans, (ii) at least 3 Business Days before
the date on which the Borrower requests the Banks to advance a Borrowing of
Term Loans which are Fixed Rate Loans, and (iii) on the date the Borrower
requests the Banks to advance a Borrowing of Base Rate Loans.  The Loans
included in each Borrowing shall bear interest initially at the type of rate
specified in such notice of a new Borrowing.  Thereafter, except with respect
to Fixed Rate Loans, the Borrower may from time to time elect to change or
continue the type of interest rate borne by each Borrowing or, subject to
Section 1.5's minimum amount requirement for each outstanding Borrowing, a
portion thereof, as follows:  (i) if such Borrowing is of Eurodollar Loans, on
the last day of the Interest Period applicable thereto, the Borrower may
continue part or all of such Borrowing as Eurodollar Loans or convert part or
all of such Borrowing into Base Rate Loans or (ii) if such Borrowing is of Base
Rate Loans, on any Business Day, the Borrower may convert all or part of such
Borrowing into Eurodollar Loans for an Interest Period or Interest Periods
specified by the Borrower.  The Borrower shall give all such notices requesting
the advance, continuation, or conversion of a Borrowing to the Agent by
telephone or telecopy (which notice shall be irrevocable once given and, if by
telephone, shall be promptly confirmed in writing), substantially in the form
attached hereto as Exhibit E (Request for New Borrowing) or Exhibit F
(Rollover/Conversion Request), as applicable, or in such other form acceptable
to the Agent.  Notices of the continuation of a Borrowing of Eurodollar Loans
for an additional Interest Period or of the conversion of part or all of a
Borrowing of Eurodollar Loans into Base Rate Loans or of Base Rate Loans into
Eurodollar Loans must be given by no later than 10:00 a.m. (Chicago time) at
least 3 Business Days before the date of the requested continuation or
conversion.  All such notices concerning the advance, continuation, or
conversion of a Borrowing shall specify the date of the requested advance,
continuation, or conversion of a Borrowing (which shall be a Business Day), the
amount of the requested Borrowing to be advanced, continued, or 





                                     -7-
<PAGE>   13

converted, the type of Loans to comprise such new, continued, or converted
Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the
Interest Period applicable thereto.  The Borrower agrees that the Agent may rely
on any such telephonic or telecopy notice given by any person the Agent in good
faith believes is an Authorized Representative without the necessity of
independent investigation, and in the event any such notice by telephone
conflicts with any written confirmation, such telephonic notice shall govern if
the Agent has acted in reliance thereon.

          (b)    Notice to the Banks.  The Agent shall give prompt telephonic
or telecopy notice to each Bank of any notice from the Borrower received
pursuant to Section 1.6(a) above and, if such notice requests the Banks to make
Eurodollar Loans, the Agent shall give notice to the Borrower and each Bank by
like means of the interest rate applicable thereto promptly after the Agent has
made such determination.

          (c)    Borrower's Failure to Notify; Automatic Continuations and
Conversions.  Any outstanding Borrowing of Base Rate Loans shall automatically
be continued for an additional Interest Period on the last day of its then
current Interest Period unless the Borrower has notified the Agent within the
period required by Section 1.6(a) that the Borrower intends to convert such
Borrowing, subject to Section 7.2 hereof, into a Borrowing of Eurodollar Loans
or such Borrowing is prepaid in accordance with Section 1.9(a).  If the
Borrower fails to give notice pursuant to Section 1.6(a) above of the
continuation or conversion of any outstanding principal amount of a Borrowing
of Eurodollar Loans before the last day of its then current Interest Period
within the period required by Section 1.6(a) or, whether or not such notice has
been given, one or more of the conditions set forth in Section 7.2 for the
continuation or conversion of a Borrowing of Eurodollar Loans would not be
satisfied (unless such conditions have been waived in accordance with the terms
of this Agreement), and such Borrowing is not prepaid in accordance with
Section 1.9(a), such Borrowing shall automatically be converted into a
Borrowing of Base Rate Loans.

          (d)    Disbursement of Loans.  Not later than 1:00 p.m. (Chicago
time) on the date of any requested advance of a new Borrowing, subject to
Section 7 hereof, each Bank shall make available its Loan comprising part of
such Borrowing in funds immediately available at the principal office of the
Agent in Chicago, Illinois.  The Agent shall make the proceeds of each new
Borrowing available to the Borrower at the Agent's principal office in Chicago,
Illinois (or by wire transfer of funds pursuant to the Borrower's written
instructions to the Agent).

          (e)    Agent Reliance on Bank Funding.  Unless the Agent shall have
been notified by a Bank prior to (or, in the case of a Borrowing of Base Rate
Loans, by 1:00 p.m. (Chicago time) on) the date on which such Bank is scheduled
to make payment to the Agent of the proceeds of a Loan (which notice shall be
effective upon receipt) that such Bank does not intend to make such payment,
the Agent may assume that such Bank has made such payment when due and the
Agent may in reliance upon such assumption (but shall not be required to) make
available to the Borrower the proceeds of the Loan to be made by such Bank and,
if any Bank has not in fact made such payment to the Agent, such Bank shall, on
demand, pay to the Agent the amount made available to the Borrower attributable
to such Bank together with interest thereon in respect of each day during the
period commencing on the date such amount was 




                                     -8-

<PAGE>   14

made available to the Borrower and ending on (but excluding) the date such Bank
pays such amount to the Agent at a rate per annum equal to (i) from the date the
related advance was made by the Agent to the date 2 Business Days after payment
by such Bank is due hereunder, the Federal Funds Rate for each such day and (ii)
from the date 2 Business Days after the date such payment is due from such Bank
to the date such payment is made by such Bank, the Base Rate in effect for each
such day. If such amount is not received from such Bank by the Agent immediately
upon demand, the Borrower will, on demand, repay to the Agent the proceeds of
the Loan attributable to such Bank with interest thereon at a rate per annum
equal to the interest rate applicable to the relevant Loan, but without such
payment being considered a payment or prepayment of a Loan under Section 1.12
hereof, so that the Borrower will have no liability under such Section with
respect to such payment.

           Section 1.7.     Interest Periods.  As provided in Section 1.6(a)
hereof, at the time of each request to advance, continue, or create by
conversion a Borrowing of Eurodollar Loans, the Borrower shall select an
Interest Period applicable to such Loans from among the available options.  The
term "Interest Period" means the period commencing on the date a Borrowing of
Loans is advanced, continued, or created by conversion and ending:  (a) in the
case of Base Rate Loans, on the last day of the calendar quarter in which such
Borrowing is advanced, continued, or created by conversion (or on the last day
of the following calendar quarter if such Loan is advanced, continued or
created by conversion on the last day of a calendar quarter) and (b) in the
case of a Eurodollar Loan, 1, 2, 3, or 6 months thereafter; provided, however,
that:
                  (a)     any Interest Period for a Borrowing of Revolving
         Loans consisting of Base Rate Loans that otherwise would end after the
         Revolving Credit Termination Date shall end on the Revolving Credit
         Termination Date, and any Interest Period for a Borrowing of Term
         Loans consisting of Base Rate Loans that otherwise would end after the
         Term Credit Final Maturity Date shall end on the Term Credit Final
         Maturity Date;

                  (b)     no Interest Period with respect to any portion of the
         Term Loans shall extend beyond the Term Loan Final Maturity Date, and
         no Interest Period with respect to any portion of the Revolving Loans
         shall extend beyond the Revolving Credit Termination Date;

                  (c)     no Interest Period with respect to any portion of the
         Term Loans consisting of Eurodollar Loans shall extend beyond a date
         on which the Borrower is required to make a scheduled payment of
         principal on the Term Loans, unless the sum of (a) the aggregate
         principal amount of Term Loans that are Base Rate Loans plus (b) the
         aggregate principal amount of Term Loans that are Eurodollar Loans
         with Interest Periods expiring on or before such date plus (c) the
         aggregate principal amount of Term Loans that are Fixed Rate Loans
         scheduled to mature on or before such date equals or exceeds the
         principal amount to be paid on the Term Loans on such payment date;

<PAGE>   15
                  (d)     whenever the last day of any Interest Period would
         otherwise be a day that is not a Business Day, the last day of such
         Interest Period shall be extended to the next succeeding Business Day,
         provided that, if such extension would cause the last day of an
         Interest Period for a Borrowing of Eurodollar Loans to occur in the
         following calendar month, the last day of such Interest Period shall be
         the immediately preceding Business Day; and

                  (e)     for purposes of determining an Interest Period for a
         Borrowing of Eurodollar Loans, a month means a period starting on one
         day in a calendar month and ending on the numerically corresponding
         day in the next calendar month; provided, however, that if there is no
         numerically corresponding day in the month in which such an Interest
         Period is to end or if such an Interest Period begins on the last
         Business Day of a calendar month, then such Interest Period shall end
         on the last Business Day of the calendar month in which such Interest
         Period is to end.

           Section 1.8.     Maturity of Loans.  (a) Revolving Loans.  Each
Revolving Loan shall mature and become due and payable by the Borrower on the
Revolving Credit Termination Date.

          (b)    Scheduled Payments of Term Loans.  The Borrower shall make
principal payments on the Term Loans in installments on the last day of each
March, June, September and December in each year, commencing with the calendar
quarter ending March 31, 2000, with the amount of each such installment to
equal 2.5% of the original aggregate principal amount of the Term Loans made to
the Borrower on or prior to the Term Credit Termination Date (with each such
installment deemed to reduce each Fixed Rate Loan then outstanding by an amount
equal to 2.5% of the original principal amount thereof), except that the final
payment of both principal and interest not sooner paid on the Term Loans shall
be due and payable on the Term Credit Final Maturity Date.  Each such principal
payment shall be applied to the Banks holding the Term Notes pro rata based
upon their Term Percentages.

           Section 1.9.     Prepayments.  (a) Optional.  The Borrower shall
have the privilege of prepaying without premium or penalty and in whole or in
part (but, if in part, then:  (i) if such Borrowing is of Base Rate Loans, in
an amount not less than $500,000, (ii) if such Borrowing is of Eurodollar Loans
or Fixed Rate Loans, in an amount not less than $500,000, and (iii) in each
case, in an amount such that the minimum amount required for a Borrowing
pursuant to Section 1.5 hereof remains outstanding) any Borrowing of Eurodollar
Loans or Fixed Rate Loans at any time upon 3 Business Days prior notice to the
Agent or, in the case of a Borrowing of Base Rate Loans, notice delivered to
the Agent by the Borrower no later than 10:00 a.m. (Chicago time) on the date
of prepayment (such notice to be in substantially the form attached hereto as
Exhibit G (Notice of Repayment) or in such other form acceptable to the Agent),
such prepayment to be made by the payment of the principal amount to be prepaid
and, in the case of any Eurodollar Loan or Fixed Rate Loan, accrued interest
thereon to the date fixed for prepayment plus any amounts due the Banks under
Section 1.12 hereof.  The Agent will promptly advise each Bank of any such
prepayment notice it receives from the Borrower.  Any amount of Revolving Loans
paid or prepaid before the Revolving Credit Termination Date may, subject to
the terms and conditions of this Agreement, be borrowed, 




                                     -10-

<PAGE>   16

repaid and borrowed again.  No amount of the Term Loans paid or prepaid may be
reborrowed.

          (b)    Mandatory.  (i)  The Borrower shall, on each date the
Revolving Credit Commitments are reduced pursuant to Section 1.13 hereof,
prepay the Revolving Loans and, if necessary, prefund the L/C Obligations by
the amount, if any, necessary to reduce the sum of the aggregate principal
amount of Revolving Loans and of L/C Obligations then outstanding to the amount
to which the Revolving Credit Commitments have been so reduced.

         (ii)    Unless the Borrower otherwise directs, prepayments of
Revolving Loans under this Section 1.9(b) shall be applied first to Borrowings
of Base Rate Loans until payment in full thereof with any balance applied to
Borrowings of Eurodollar Loans in the order in which their Interest Periods
expire.  Each prepayment of Revolving Loans under this Section 1.9(b) shall be
made by the payment of the principal amount to be prepaid and accrued interest
thereon to the date of prepayment together with any amounts due the Banks under
Section 1.12 hereof.  Each prefunding of L/C Obligations shall be made in
accordance with Section 9.4 hereof.

          Section 1.10.     Default Rate.  Notwithstanding anything to the
contrary contained in Section 1.4 hereof, while any Event of Default exists or
after acceleration, the Borrower shall pay interest (after as well as before
entry of judgment thereon to the extent permitted by law) on the principal
amount of all Loans (computed on the basis of a year of 360 days and actual
days elapsed) at a rate per annum equal to:

                  (a)     for any Base Rate Loan, the sum of 2% plus the
         Applicable Margin plus the Base Rate from time to time in effect;

                  (b)     for any Eurodollar Loan, the sum of 2% plus the rate
         of interest in effect thereon at the time of such default until the
         end of the Interest Period applicable thereto and, thereafter, at a
         rate per annum equal to the sum of 2% plus the Applicable Margin for
         Base Rate Loans plus the Base Rate from time to time in effect; and

                  (c)     for any Fixed Rate Loan, the sum  2% plus the
         interest in effect thereon at the time of such default;

provided, however, that (i) in the event any Fixed Rate Loan, or portion
thereof, is not paid when due, the overdue amount thereof shall bear interest
at the rate per annum equal to the rate per annum applicable to Base Rate Loans
hereunder after default and (ii) in the absence of acceleration, any other
adjustments pursuant to this Section 1.10 shall be made at the election of the
Required Banks with written notice to the Borrower.  While any Event of Default
exists or after acceleration, interest shall be paid on demand of the Agent at
the request or with the consent of the Required Banks.

          Section 1.11.     The Notes.  (a) The Revolving Loans made to the
Borrower by a Bank shall be evidenced by a single promissory note of the
Borrower issued to such Bank in the 



                                     -11-


<PAGE>   17

form of Exhibit B hereto.  Each such promissory note is hereinafter referred to
as a "Revolving Note" and collectively such promissory notes are referred to as
the "Revolving Notes."

          (b)    The Terms Loans made to the Borrower by a Bank shall be
evidenced by a single promissory note of the Borrower issued to such Bank in
the form of Exhibit C hereto.  Each such promissory note is hereinafter
referred to as a "Term Note" and collectively such promissory notes are
referred to as the "Term Notes."

          (c)    Each Bank shall record on its books and records or on a
schedule to its appropriate Note the amount of each Loan advanced, continued or
converted by it, all payments of principal and interest and the principal
balance from time to time outstanding thereon, the type of such Loan, and, for
any Eurodollar Loan, the Interest Period and, for any Eurodollar Loan or Fixed
Rate Loan, the interest rate applicable thereto.  The record thereof, whether
shown on such books and records of a Bank or on a schedule to the relevant
Note, shall be prima facie evidence as to all such matters; provided, however,
that the failure of any Bank to record any of the foregoing or any error in any
such record shall not limit or otherwise affect the obligation of the Borrower
to repay all Loans made to it hereunder together with accrued interest thereon.
At the request of any Bank and upon such Bank tendering to the Borrower the
appropriate Note to be replaced, the Borrower shall furnish a new Note to such
Bank to replace any outstanding Note, and at such time the first notation
appearing on a schedule on the reverse side of, or attached to, such Note shall
set forth the aggregate unpaid principal amount of all Loans, if any, then
outstanding thereon.

          Section 1.12.     Funding/Hedging Indemnity.  If any Bank or the
Floating Rate Payor 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 such Bank or Floating Rate Payor to fund or maintain any Eurodollar Loan or
Fixed Rate Loan or the relending or reinvesting of such deposits or amounts
paid or prepaid to such Bank or, with respect to any Fixed Rate Loans, by
reason of the prepayment under or termination, in whole or in part, of any
interest rate hedging arrangement entered into by the Floating Rate Payor with
respect thereto) as a result of:

                  (a)     any payment, prepayment or conversion of a Eurodollar
         Loan on a date other than the last day of its Interest Period, or any
         payment or prepayment of a Fixed Rate Loan on a date other than a
         regularly scheduled payment date therefor as provided in Section
         1.8(b) hereof,

                  (b)     any failure (because of a failure to meet the
         conditions of Section 7 or otherwise) by the Borrower to borrow a
         Fixed Rate Loan, or to borrow or continue a Eurodollar Loan, or to
         convert a Base Rate Loan into a Eurodollar Loan, on the date specified
         in a notice given pursuant to Section 1.6(a),

                  (c)     any failure by the Borrower to make any payment of
         principal on any Eurodollar Loan or Fixed Rate Loan when due (whether
         by acceleration or otherwise), or





                                     -12-

<PAGE>   18

                  (d)     any acceleration of the maturity of a Eurodollar Loan
         or Fixed Rate Loan as a result of the occurrence of any Event of
         Default hereunder,

then, upon the demand of such Bank or Floating Rate Payor, the Borrower shall
pay to such Bank or Floating Rate Payor such amount as will reimburse such Bank
or Floating Rate Payor for such loss, cost or expense.  If any Bank or the
Floating Rate Payor makes such a claim for compensation, it shall provide to
the Borrower, with a copy to the Agent, a certificate setting forth the amount
of such loss, cost or expense in reasonable detail (including an explanation of
the basis for and the computation of such loss, cost or expense) and the
amounts shown on such certificate shall be conclusive if reasonably determined.

          Section 1.13.     Commitment Terminations.  (a) Optional Revolving
Credit Terminations.  The Borrower shall have the right at any time and from
time to time, upon 3 Business Days prior written notice to the Agent, to
terminate the Revolving Credit Commitments without premium or penalty and in
whole or in part, any partial termination to be (i) in an amount not less than
$1,000,000 and (ii) allocated ratably among the Banks in proportion to their
respective Revolver Percentages, provided that the Revolving Credit Commitments
may not be reduced to an amount less than the sum of the aggregate principal
amount of Revolving Loans and of L/C Obligations then outstanding.  Any
termination of the Revolving Credit Commitments below $2,500,000 shall reduce
the L/C Commitment by a like amount.  The Agent shall give prompt notice to
each Bank of any such termination of the Revolving Credit Commitments.

          (b)    Optional Term Credit Terminations.  The Borrower shall have
the right at any time and from time to time, upon 3 Business Days prior written
notice to the Agent, to terminate the Term Credit Commitments without premium
or penalty and in whole or in part, any partial termination to be (i) in an
amount not less than $1,000,000 and (ii) allocated ratably among the Banks in
proportion the their respective Term Percentages.  The Agent shall give prompt
notice to each Bank of any such termination of the Term Credit Commitments

          (c)    Mandatory Revolving Credit Terminations.  On the date of
receipt thereof by the Borrower or any Subsidiary, the Revolving Credit
Commitments shall ratably terminate by an amount equal to 100% of the net cash
proceeds (i.e., gross proceeds of cash or cash equivalent minus reasonable
costs directly incurred and payable as a result thereof) of the incurrence
after the date of this Agreement of Indebtedness for Borrowed Money by the
Borrower or any Subsidiary (other than (x) the Loans hereunder and (y) such
other Indebtedness for Borrowed Money permitted by Section 8.13 hereof), it
being expressly understood and agreed that any such mandatory termination of
the Revolving Credit Commitments hereunder as a result of the foregoing shall
be in addition to any and all other rights and remedies that the Banks may have
as a result of any breach of the terms of Section 8.13 hereof.

          (d)    Mandatory Termination Upon a Change of Control.  After the
occurrence of a Change of Control, the Required Banks may, by written notice to
the Borrower at any time on or before the date occurring 90 days after the date
the Borrower notifies the Banks of such Change of Control, terminate the
remaining Commitments and all other obligations of the Banks hereunder on the
date stated in such notice (which shall in no event be sooner than 




                                     -13-

<PAGE>   19

30 days after the occurrence of such Change of Control).  On the date the
Commitments are so terminated, all outstanding Obligations (including, without
limitation, all principal of and accrued interest on the Notes) shall forthwith
be due and payable without further demand, presentment, protest, or notice of
any kind and the Borrower shall immediately pay to the Banks the full amount
then available for drawing under each Letter of Credit, such amount to be held
in the Account referred to in Section 9.4 hereof (the Borrower agreeing to
immediately make such payment on the date the Commitments are so terminated and
acknowledging and agreeing that the Banks would not have an adequate remedy at
law for the failure by the Borrower to honor any such demand and that the Banks,
and the Agent on their behalf, shall have the right to require the Borrower to
specifically perform such undertaking whether or not any drawings or other
demands for payment have been made under any of the Letters of Credit).

          (e)    Any termination of the Commitments pursuant to this Section
1.13 may not be reinstated.  

SECTION 2.             FEES, EXTENSIONS, AND SUBSTITUTION OF BANKS.

           Section 2.1.     Fees.  (a)     Revolving Credit Commitment Fee.
The Borrower shall pay to the Agent for the ratable account of the Banks in
accordance with their Revolver Percentages a commitment fee at the rate per
annum equal to the Applicable Margin (computed on the basis of a year of 360
days and the actual number of days elapsed) on the average daily Unused
Revolving Credit Commitments.  Such commitment fee shall be payable
quarter-annually in arrears on the last day of each March, June, September and
December in each year (commencing March 31, 1998) and on the Revolving Credit
Termination Date, unless the Revolving Credit Commitments are terminated in
whole on an earlier date, in which event the commitment fee for the period to
the date of such termination in whole shall be paid on the date of such
termination.

          (b)    Term Credit Commitment Fee.  The Borrower shall pay to the
Agent for the ratable account of the Banks in accordance with their Term
Percentages a commitment fee at the rate per annum equal to the Applicable
Margin (computed on the basis of a year of 360 days and the actual number of
days elapsed) on the average daily undrawn Term Credit Commitments.  Such
commitment fee shall be payable quarter-annually in arrears on the last day of
each March, June, September and December in each year (commencing March 31,
1998) and on the Term Credit Termination Date, unless the Term Credit
Commitments are terminated in whole on an earlier date, in which event the
commitment fee for the period to the date of such termination in whole shall be
paid on the date of such termination.

          (c)    Letter of Credit Fees.  On the date of issuance or extension,
or increase in the amount, of any Letter of Credit pursuant to Section 1.2
hereof, the Borrower shall pay to the Agent for its own account an issuance fee
equal to .25% per annum of the face amount of (or of the increase in the face
amount of) such Letter of Credit.  Quarterly in arrears, on the last day of
each calendar quarter, commencing on March 31, 1998, the Borrower shall pay to
the Agent, for the ratable benefit of the Banks in accordance with their

Applicable Margin (computed on the basis 



                                     -14-

<PAGE>   20

of a year of 360 days and the actual number of days elapsed) in effect during
each day of such quarter applied to the daily average face amount of Letters of
Credit outstanding during such quarter.  In addition, the Borrower shall pay to
the Agent for its own account the Agent's standard drawing, negotiation,
amendment, and other administrative fees for each Letter of Credit.  Such
standard fees referred to in the preceding sentence may be established by the
Agent from time to time.

          (d)    Agent Fees.  The Borrower shall pay to the Agent the fees
agreed to between the Agent and the Borrower in a letter dated December 19,
1997 or as otherwise agreed between them.

          (e)    Audit Fees.  The Borrower shall pay to the Agent for its own
use and benefit charges for audits of the Collateral performed by the Agent or
its agents or representatives in such amounts as the Agent may from time to
time request (the Agent acknowledging and agreeing that such charges shall be
computed in the same manner as it at the time customarily uses for the
assessment of charges for similar collateral audit and, in any event, not in
excess of $10,000 for any single audit); provided, however, that in the absence
of any Default and Event of Default, the Borrower shall not be required to pay
the Agent for more than (i) two (2) such audits during the initial 12 months of
this Agreement and (ii) one (1) such audit during each 12 month period ending
thereafter.

           Section 2.2.     Extensions of the Revolving Credit Termination
Date.  No later than 90 days before the Revolving Credit Termination Date, the
Borrower may make a request for a one year extension of the Revolving Credit
Termination Date in a written notice to the Agent.  The Agent will promptly
inform the Banks of any such request, and each Bank shall notify the Agent in
writing within 60 days following such request whether such Bank agrees to the
requested extension.  If a Bank fails to so notify the Agent whether such Bank
agrees to such extension, such Bank shall be deemed to have refused to grant
the requested extension.  Upon receipt by the Agent of the written consent of
all the Banks, the Revolving Credit Termination Date shall be automatically
extended an additional year.  Otherwise, the Revolving Credit Termination Date
will remain as scheduled, at which time all Revolving Loans and all other
Obligations relating to the Revolving Credit shall be due and payable.  In the
event any extension is granted hereunder, the Borrower shall, and shall cause
each Subsidiary to, execute and deliver such additional instruments and
documents as the Agent may reasonably deem necessary or appropriate to reflect
any such extension.  All costs and expenses incurred by the Agent in connection
with each extension request (including reasonable attorneys' fees) shall be
paid by the Borrower in accordance with Section 12.15 hereof.

           Section 2.3.     Substitution of Banks.  Upon the receipt by the
Borrower of (a) a claim from any Bank for compensation under Section 10.3 or
12.1 hereof, (b) notice by any Bank to the Borrower of any illegality pursuant
to Section 10.1 hereof or (c) notice from the Agent that a Bank or Banks have
not approved an extension of the Termination Date pursuant to Section 2.2
hereof, or in the event any Bank is in default in any material respect with
respect to its obligations under the Loan Documents (herein, a "Defaulting
Bank") (any such Bank referred to in clause (a), (b), or (c) above, or any such
Defaulting Bank, being hereinafter referred to as an "Affected Bank"), the
Borrower may, in addition to any other rights the 




                                     -15-

<PAGE>   21

Borrower may have hereunder or under applicable law, require, at its expense,
any such Affected Bank to assign, at par plus accrued interest and fees, without
recourse, all of its interest, rights and obligations hereunder (including all
of its Commitments and the Loans and participation interests in Letters of
Credit and other amounts at any time owing to it hereunder and the other Loan
Documents) to a bank or other institutional lender specified by the Borrower,
provided that (i) such assignment shall not conflict with or violate any law,
rule, or regulation or order of any court or other governmental authority, (ii)
the Borrower shall have received the written consent of the Agent, which consent
shall not be unreasonably withheld, to such assignment, (iii) the Borrower shall
have paid to the Affected Bank all monies other than such principal, interest,
and fees accrued and owing to it hereunder, and (iv) the assignment is entered
into in accordance with the other requirements of Section 12.12 hereof.  

SECTION 3. PLACE AND APPLICATION OF PAYMENTS.

         All payments of principal of and interest on the Loans and the

under this Agreement and the other Loan Documents, shall be made by the
Borrower to the Agent by no later than 12:00 Noon (Chicago time) on the due
date thereof at the office of the Agent in Chicago, Illinois (or such other
location in the State of Illinois as the Agent may designate to the Borrower)
for the benefit of the Bank or Banks entitled thereto.  Any payments received
after such time shall be deemed to have been received by the Agent on the next
Business Day.  All such payments shall be made in U.S. Dollars, in immediately
available funds at the place of payment, in each case without set-off or
counterclaim.  The Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal or interest on Loans and on
Reimbursement Obligations in which the Banks have purchased Participating
Interests ratably to the Banks and like funds relating to the payment of any
other amount payable to any Bank to such Bank, in each case to be applied in
accordance with the terms of this Agreement.

         Anything contained herein to the contrary notwithstanding, all
payments and collections received in respect of the Obligations and all
proceeds of the Collateral received, in each instance, by the Agent or any of
the Banks after the occurrence and during the continuation of an Event of
Default shall be remitted to the Agent and distributed as follows:

                  (a)     first, to the payment of any outstanding costs and
         expenses reasonably incurred by the Agent, and any security trustee
         therefor, in monitoring, verifying, protecting, preserving or
         enforcing the Liens on the Collateral or by the Agent, and any
         security trustee therefor, in protecting, preserving or enforcing
         rights under the Loan Documents, and in any event all costs and
         expenses of a character which the Borrower has agreed to pay the Agent
         under Section 12.15 hereof (such funds to be retained by the Agent for
         its own account unless it has previously been reimbursed for such
         costs and expenses by the Banks, in which event such amounts shall be
         remitted to the Banks to reimburse them for payments theretofore made
         to the Agent);

                  (b)     second, to the payment of any outstanding interest or
         other fees or amounts due under the Notes and the other Loan Documents
         (including amounts owing to the Banks or the Floating Rate Payor under
         Section 1.12 hereof), in each case other than for 



                                     -16-

<PAGE>   22

         principal on the Loans or in reimbursement or collateralization
         of L/C Obligations, pro rata as among the Agent and the Banks in accord
         with the amount of such interest and other fees or amounts owing each;

                  (c)     third, to the payment of the principal of the Notes
         and any unpaid Reimbursement Obligations and to the Agent to be held
         as collateral security for any other L/C Obligations (until the Agent
         is holding an amount of cash equal to the then outstanding amount of
         all such L/C Obligations), the aggregate amount paid to or held as
         collateral security for the Banks to be allocated pro rata as among
         the Banks in accord with the aggregate unpaid principal balances of
         their Loans and interests in the Letters of Credit;

                  (d)     fourth, to the Agent and the Banks ratably in
         accordance with the amounts of any other indebtedness, obligations or
         liabilities of the Borrower and its Subsidiaries owing to each of them
         and secured by the Collateral Documents (other than for Hedging
         Liability described in subsection (e) below), unless and until all

the Borrower acknowledging that the Agent has (and is hereby granted) a lien on
such accounts and all funds contained therein to secure the Obligations.  If
and to the extent that proceeds are deposited in accounts maintained with
financial institutions other than the Agent, it shall be a condition to the
Borrower's or any Material Subsidiary's right to so effect such deposits more
than 30 days after the date hereof that the financial institutions maintaining
such accounts have delivered to the Agent blocked account agreements
satisfactory to the Agent in form and substance pursuant to which such
financial institutions acknowledge the Agent's Lien thereon, waive any right of
offset or bankers' liens thereon (other than with respect to account
maintenance charges and returned items) and agree that the collected balances
in such accounts will only be transferred to the Agent.  The Banks agree with
the Borrower that if and so long as no Default or Event of Default has occurred
or is continuing, amounts on deposit in the accounts maintained with the Agent
will (subject to the rules and regulations of the Agent as from time to time in
effect applicable to demand deposit accounts) be made available to the Borrower

the occurrence of an Event of Default, the Agent may apply the funds on deposit
in such accounts to the Obligations.

           Section 4.3.     Guaranties.  The payment and performance of the
Obligations shall at all times be guaranteed by each direct and indirect
Material Subsidiary of the Borrower pursuant to one or more guaranty agreements
in form and substance acceptable to the Agent, as the same may be amended,
modified or supplemented from time to time (individually a "Guaranty" and
collectively the "Guaranties").

           Section 4.4.     Further Assurances.   The Borrower agrees that it
shall, and shall cause each Material Subsidiary to, from time to time at the
request of the Agent or the Required Banks, execute and deliver such documents

Collateral.  In the event any Subsidiary hereinafter becomes a Material
Subsidiary or the Borrower or any Material Subsidiary forms or acquires any
other Material Subsidiary after

and expense, such other instruments, documents, certificates, and opinions
reasonably required by the Agent in connection therewith.

event that the Borrower or any Material Subsidiary owns or hereafter acquires
any real property, at the request of the Agent or the Required Banks pursuant

Agent for the purpose of granting to the Agent for the benefit of the Banks a
lien on such real property to secure the Obligations, shall pay all taxes,
costs and expenses incurred by the Agent in recording such mortgage or deed of
trust, and shall at its expense supply to the Agent a survey and a mortgagee's
policy of title insurance from a title insurer reasonably acceptable to the
Agent insuring the validity of such mortgage or deed of trust and its status as
a first lien (subject to liens permitted by this Agreement) on the real
property encumbered thereby.

SECTION 6.             REPRESENTATIONS AND WARRANTIES.

         The Borrower represents and warrants to the Agent and the Banks as
follows:

duly organized, validly existing and in good standing as a corporation under
the laws of the state of its incorporation, has full and adequate corporate
power to own its Property and conduct its business as now conducted, and is
duly licensed or qualified and in good standing in each jurisdiction in which
the nature of the business conducted by it or the nature of the Property owned
or leased by it requires such licensing or qualifying, except where the failure

           Section 6.2.     Subsidiaries.  Each Subsidiary is duly organized,
validly existing and in good standing under the laws of the jurisdiction in
which it is incorporated or organized, as the case may be, has full and

and is duly licensed or qualified and in good standing in each jurisdiction in
which the nature of the business conducted by it or the nature of the Property
owned or leased by it requires such licensing or qualifying, except where the
failure to do so would not have a Material Adverse Effect.  Schedule 6.2 hereto
(as the same may be deemed amended pursuant to Section 8.16(c) or 8.23 hereof)
identifies each Subsidiary, the jurisdiction of its incorporation or
organization, as the case may be, the percentage of issued and outstanding
shares of each class of its capital stock or other equity interests owned by
the Borrower and the other Subsidiaries and, if such percentage is not 100%
(excluding directors' qualifying shares 





                                     -31-

<PAGE>   37

as required by law), a description of each class of its authorized capital stock
and other equity interests and the number of shares of each class issued and
outstanding.  All of the outstanding shares of capital stock and other equity
interests of each Subsidiary are validly issued and outstanding and fully paid
and nonassessable and all such shares and other equity interests indicated on
Schedule 6.2 (as the same may be deemed amended pursuant to Section 8.16(c) or
8.23 hereof) as owned by the Borrower or a Subsidiary are owned, beneficially
and of record, by the Borrower or such Subsidiary free and clear of all Liens
other than the Liens granted in favor of the Agent pursuant to the Collateral
Documents.  There are no outstanding commitments or other obligations of any
Subsidiary to issue, and no options, warrants or other rights of any Person to
acquire, any shares of any class of capital stock or other equity interests of
any Subsidiary.

           Section 6.3.     Authority and Validity of Obligations.  The
Borrower has full right and authority to enter into this Agreement and the
other Loan Documents executed by it, to make the borrowings herein provided
for, to issue its Notes in evidence thereof, to grant to the Agent the Liens
described in the Collateral Documents executed by the Borrower, and to perform
all of its obligations hereunder and under the other Loan Documents executed by
it.  Each Material Subsidiary has full right and authority to enter into the
Loan Documents executed by it, to guarantee the Obligations, to grant to the
Agent the Liens described in the Collateral Documents executed by such Person,
and to perform all of its obligations under the Loan Documents executed by it.
The Loan Documents delivered by the Borrower and by each Subsidiary have been
duly authorized, executed and delivered by such Person and constitute valid and
binding obligations of such Person enforceable in accordance with their terms
except as enforceability may be limited by bankruptcy, insolvency, fraudulent
conveyance or similar laws affecting creditors' rights generally and general
principles of equity (regardless of whether the application of such principles
is considered in a proceeding in equity or at law); and this Agreement and the
other Loan Documents do not, nor does the performance or observance by the
Borrower or any Subsidiary of any of the matters and things herein or therein
provided for, (a) contravene or constitute a default under any provision of law
or any judgment, injunction, order or decree binding upon the Borrower or any
Subsidiary or any provision of the charter, articles of incorporation or
by-laws of the Borrower or any Subsidiary, (b) contravene or constitute a
default under any covenant, indenture or agreement of or affecting the Borrower
or any Subsidiary or any of its Property, in each case where such contravention
or default is reasonably likely to have a Material Adverse Effect, or (c)
result in the creation or imposition of any Lien on any Property of the
Borrower or any Subsidiary other than the Liens granted in favor of the Agent
pursuant to the Collateral Documents.

           Section 6.4.     Use of Proceeds; Margin Stock.  The Borrower shall
use the proceeds of (i) the Term Loans solely for the purposes set forth in
Section 1.3 hereof and (ii) the Revolving Loans and other extensions of credit
made available hereunder for its general working capital purposes and such
other legal and proper purposes as are consistent with all applicable laws.
Neither the Borrower nor any Subsidiary is engaged in the business of extending
credit for the purpose of purchasing or carrying margin stock (within the
meaning of Regulation U of the Board of Governors of the Federal Reserve
System), and no part of the proceeds of any Loan or any other extension of
credit made hereunder will be used to purchase or carry any such margin stock
or to extend credit to others for the purpose of purchasing or 





                                     -32-

hereunder.

the periods then ended in conformity with GAAP applied on a consistent basis.

are material to it other than as indicated on such financial statements or
which have been incurred after such date with respect to Acquisitions
consummated prior to the date of this Agreement and either disclosed on
Schedule 6.7 attached hereto or disclosed to the Banks in the written materials
delivered to the Banks pursuant to Section 6.7 hereof or, with respect to
future periods, on the financial statements furnished pursuant to Section 8.5

1997, there has been no change in the condition (financial or otherwise) or
business prospects of the Borrower or any Subsidiary, except those occurring in
the ordinary course of business and in connection with the Acquisitions
consummated prior to the date of this Agreement, none of which individually or
in the aggregate have been materially adverse.

Schedule 6.7 hereof and the statements and information furnished by Borrower to
the Banks in connection with the negotiation of this Agreement and the other
Loan Documents and the commitments by the Banks to provide all or part of the
financing contemplated hereby do not contain any untrue statements of a
material fact or omit a material fact necessary to make the material statements
contained herein or therein, in the light of the circumstances under which they
were made, not misleading, the Banks acknowledging that any projections and
other forward-looking statements regarding future expectations and the beliefs
(the "Statements") furnished by the Borrower to the Banks are subject to risks
and uncertainties which could cause actual results to differ materially from
the Statements made by the Borrower and that the Borrower only represents that
at the time the Statements were made by the Borrower to the Banks, the Borrower
did not know of any material facts that would cause the Statements to be
untrue.

likely to result in revocation or denial of any material license, permit, or
approval, or of any right to receive reimbursement or payments under Medicare
or other governmental third-party reimbursement or prospective payment program,
is pending or, to the knowledge of the Borrower, threatened.

assets in the ordinary course of business), subject to no Liens other than such
thereof as are permitted by Section 8.14 hereof and Liens in favor of

including any disposition of Property as part of a sale and leaseback

                  (a)     the sale or lease of inventory in the ordinary course
         of business, or the lease of equipment or real property in the
         ordinary course of business to a provider, or professional association

                  (b)     the sale, transfer, lease, or other disposition of
         Property of the Borrower or any Subsidiary to one another in the

         merger;

                  (d)     the sale of delinquent notes or accounts receivable
         in the ordinary course of business for purposes of collection only
         (and not for the purpose of any bulk sale or securitization

                  (e)     the sale, transfer, or other disposition of any
         tangible personal property that, in the reasonable business judgment
         of the Borrower or its Subsidiary, has become uneconomical, obsolete,
         or worn out, and which is disposed of in the ordinary course of
         business; and

provided, however, that during the existence of any Default or Event of

written notice of any such event and, immediately after giving effect to any
such merger, Schedule 6.2 of this Agreement shall be deemed amended excluding

operate to prevent (i) the Lien on the capital stock of each Subsidiary granted
to the Agent pursuant to the Collateral Documents, (ii) the issuance, sale and
transfer to any person of any shares of capital stock of a Subsidiary solely
for the purpose of qualifying, and to the extent legally necessary to qualify,
such person as a director of such Subsidiary, and (iii) any transaction
permitted by Section 8.16(c) above.

          Section 8.18.     Dividends and Certain Other Restricted Payments.

in respect of any class or series of its capital stock (other than dividends
payable solely in its capital stock) or (ii) directly or indirectly purchase,
redeem or otherwise acquire or retire any of its capital stock; provided,
however, that the foregoing shall not operate to prevent (a) the making of
dividends or distributions by any Wholly-Owned Subsidiary to its parent
corporation or (b) the redemption by the Borrower of its capital stock from
LaserSight Incorporated pursuant to the terms of the Stock Distribution
Agreement dated December 30, 1997, between Laser Sight Incorporated and the

Event of Default exists.

          Section 8.19.     ERISA.  The Borrower shall, and shall cause each
Subsidiary to, promptly pay and discharge all obligations and liabilities
arising under ERISA pertaining to a Plan of a character which if unpaid or
unperformed is reasonably likely to result in the imposition of a Lien against
any of its Properties.  The Borrower shall, and shall cause each Subsidiary to,
promptly notify the Agent of (i) the occurrence of any reportable event (as
defined in ERISA) with respect to a Plan, (ii) receipt of any notice from the
PBGC of its intention to seek termination of any Plan or appointment of a
trustee therefor, (iii) its intention to terminate or withdraw from any Plan,
and (iv) the occurrence of any event with respect to any Plan which would
result in the incurrence by the Borrower or any Subsidiary of any material
liability, fine or penalty, or any material increase in the contingent
liability of the Borrower or any Subsidiary with respect to any post-retirement
Welfare Plan benefit.

          Section 8.20.     Compliance with Laws.  The Borrower shall, and
shall cause each Subsidiary to, comply in all respects with the requirements of
all federal, state and local laws, rules, regulations, ordinances and orders
applicable to or pertaining to its Properties or business operations, where any
such non-compliance, individually or in the aggregate, is reasonably likely to
have a Material Adverse Effect or is reasonably likely to result in a Lien upon
any of their Property.

          Section 8.21.     Burdensome Contracts With Affiliates.  The Borrower
shall not, nor shall it permit any Subsidiary to, enter into any contract,
agreement or business arrangement with any of its Affiliates on terms and
conditions which are less favorable to the Borrower or such Subsidiary than
would be usual and customary in similar contracts, agreements or business
arrangements between Persons not affiliated with each other.

formation or acquisition of any Subsidiary, the Borrower shall provide the

shall not, nor shall it permit any Subsidiary to, engage in any business or
activity if as a result the general nature of the business of the Borrower or
any Subsidiary would be changed in any material respect from the general nature
of the business engaged in by it as of the date of this Agreement or as of the
date such Person becomes a Subsidiary hereunder.

          Section 8.25.     Change in Capital Structure.  Except for the
authorization and/or issuance of additional common stock, the Borrower shall
not change its capital structure or authorize or issue any other equity

stock) without the prior written consent of the Required Banks.

credit extended under this Agreement solely for the purposes set forth in, or
otherwise permitted by, Section 6.4 hereof.

Except as provided herein, the Borrower shall not, nor shall it permit any
Subsidiary to, directly or indirectly create or otherwise cause or suffer to

                  (e)     any event occurs or condition exists (other than
         those described in subsections (a) through (d) above) which is
         specified as an event of default under any of the other Loan
         Documents, or any of the Loan Documents, or any material provisions
         thereof, shall for any reason not be or shall cease to be in full
         force and effect or is declared to be null and void, or any of the
         Collateral Documents shall for any reason fail to create a valid and

         terms thereof, or the Borrower or any Subsidiary takes any action for

         guaranteed by the Borrower or any Subsidiary, or under any indenture,
         agreement or other instrument under which the same may be issued, and
         such default shall continue for a period of time sufficient to permit
         the acceleration of the maturity of any such Indebtedness for Borrowed
         Money (whether or not such maturity is in fact accelerated), or any
         such Indebtedness for Borrowed Money shall not be paid when due
         (whether by demand, lapse of time, acceleration or otherwise);

                  (g)     any judgment or judgments, writ or writs or warrant

         administrator or any combination of the foregoing; or the PBGC shall
         institute proceedings under Title IV of ERISA to terminate or to cause

         proceeding shall be instituted by a fiduciary of any Material Plan
         against the Borrower or any Subsidiary, or any member of its
         Controlled Group, to enforce Section 515 or 4219(c)(5) of ERISA and
         such proceeding shall not have been dismissed within 30 days
         thereafter; or a condition shall exist by reason of which the PBGC
         would be entitled to obtain a decree adjudicating that any Material
         Plan must be terminated;

                  (i)     the Borrower or any Subsidiary shall (i) have entered
         involuntarily against it an order for relief under the United States
         Bankruptcy Code, as amended, (ii) not pay, or admit in writing its

         to have entered against it an order for relief under the United States
         Bankruptcy Code, as amended, to adjudicate it insolvent, or seeking
         dissolution, winding up, liquidation, reorganization, arrangement,
         adjustment or composition of it or its debts under any law relating to

         action in furtherance of any matter described in parts (i) through (v)
         above, or (vii) fail to contest in good faith any appointment or

                  (j)     a custodian, receiver, trustee, examiner, liquidator
         or similar official shall be appointed for the Borrower or any
         Subsidiary or any substantial part of any of its Property, or a
         proceeding described in Section 9.1(i)(v) shall be instituted against
         the Borrower or any Subsidiary, and such appointment continues
         undischarged or such proceeding continues undismissed or unstayed for
         a period of 30 days; or

                  (k)     one or more long-term management agreements pursuant
         to which the Borrower or any Subsidiary provides management and/or
         administrative services is terminated or cancelled prior to its
         scheduled termination date (whether as a result of a breach by the
         Borrower or such Subsidiary thereunder or otherwise) or any advisory
         agreement pursuant to which one or more Persons provide advisory
         services to the Borrower or any Subsidiary in connection with
         identifying potential Acquisitions is terminated or cancelled prior to
         its scheduled termination date (whether as a result of a 





                                    -51-

<PAGE>   57

         breach by the Borrower or such Subsidiary thereunder or otherwise)
         and, in the reasonable judgment of the Required Banks, any such
         termination or cancellation is reasonably likely to have a Material
         Adverse Effect.

           Section 9.2.     Non-Bankruptcy Defaults.  When any Event of Default
other than those described in subsection (i) or (j) of Section 9.1 hereof has
occurred and is continuing, the Agent shall, by written notice to the Borrower:
(a) if so directed by the Required Banks, terminate the remaining Commitments
and all other obligations of the Banks hereunder on the date stated in such
notice (which may be the date thereof); (b) if so directed by the Required
Banks, declare the principal of and the accrued interest on all outstanding
Notes to be forthwith due and payable and thereupon all outstanding Notes,
including both principal and interest thereon, shall be and become immediately
due and payable together with all other amounts payable under the Loan
Documents without further demand, presentment, protest or notice of any kind;
and (c) if so directed by the Required Banks, demand that the Borrower
immediately pay to the Agent the full amount then available for drawing under
each or any Letter of Credit, and the Borrower agrees to immediately make such
payment and acknowledges and agrees that the Banks would not have an adequate
remedy at law for failure by the Borrower to honor any such demand and that the
Agent, for the benefit of the Banks, shall have the right to require the
Borrower to specifically perform such undertaking whether or not any drawings
or other demands for payment have been made under any Letter of Credit.  The
Agent, after giving notice to the Borrower pursuant to Section 9.1(c) or this
Section 9.2, shall also promptly send a copy of such notice to the other Banks,
but the failure to do so shall not impair or annul the effect of such notice.

           Section 9.3.     Bankruptcy Defaults.  When any Event of Default
described in subsections (i) or (j) of Section 9.1 hereof has occurred and is
continuing, then all outstanding Notes shall immediately become due and payable
together with all other amounts payable under the Loan Documents without
presentment, demand, protest or notice of any kind, the obligation of the Banks
to extend further credit pursuant to any of the terms hereof shall immediately
terminate and the Borrower shall immediately pay to the Agent the full amount
then available for drawing under all outstanding Letters of Credit, the
Borrower acknowledging and agreeing that the Banks would not have an adequate
remedy at law for failure by the Borrower to honor any such demand and that the
Banks, and the Agent on their behalf, shall have the right to require the
Borrower to specifically perform such undertaking whether or not any draws or
other demands for payment have been made under any of the Letters of Credit.

           Section 9.4.     Collateral for Undrawn Letters of Credit.  (a) If
the prepayment of the amount available for drawing under any or all outstanding
Letters of Credit is required under Section 1.9(b) or under Section 9.2 or 9.3
above, the Borrower shall forthwith pay the amount required to be so prepaid,
to be held by the Agent as provided in subsection (b) below.

          (b)    All amounts prepaid pursuant to subsection (a) above shall be
held by the Agent in a separate collateral account (such account, and the
credit balances, properties and any investments from time to time held therein,
and any substitutions for such account, any certificate of deposit or other
instrument evidencing any of the foregoing and all proceeds of 




                                    -52-

<PAGE>   58

and earnings on any of the foregoing being collectively called the "Account")
as security for, and for application by the Agent (to the extent available) to,
the reimbursement of any payment under any Letter of Credit then or thereafter
made by the Agent, and to the payment of the unpaid balance of any Loans and
all other Obligations.  The Account shall be held in the name of and subject to
the exclusive dominion and control of the Agent for the benefit of the Agent
and the Banks.  If and when requested by the Borrower, the Agent shall invest
funds held in the Account from time to time in direct obligations of, or
obligations the principal of and interest on which are unconditionally
guaranteed by, the United States of America with a remaining maturity of one
year or less, provided that the Agent is irrevocably authorized to sell
investments held in the Account when and as required to make payments out of
the Account for application to amounts due and owing from the Borrower to the
Agent or Banks; provided, however, that if (i) the Borrower shall have made
payment of all such obligations referred to in subsection (a) above, (ii) all
relevant preference or other disgorgement periods relating to the receipt of
such payments have passed, and (iii) no Letters of Credit, Commitments, Loans
or other Obligations remain outstanding hereunder, then the Agent shall release
to the Borrower any remaining amounts held in the Account.

           Section 9.5.     Notice of Default.  The Agent shall give notice to
the Borrower under Section 9.1(c) hereof promptly upon being requested to do so
by any Bank and shall thereupon notify all the Banks thereof.

           Section 9.6.     Expenses.  The Borrower agrees to pay to the Agent
and each Bank, and any other holder of any Note outstanding hereunder, all
expenses reasonably incurred or paid by the Agent and such Bank or any such
holder, including reasonable attorneys' fees and court costs, in connection
with any Default or Event of Default by the Borrower hereunder or in connection
with the enforcement of any of the Loan Documents.

SECTION 10.            CHANGE IN CIRCUMSTANCES.

          Section 10.1.     Change of Law.  Notwithstanding any other
provisions of this Agreement or any Note, if at any time any change in
applicable law or regulation or in the interpretation thereof makes it unlawful
for any Bank to make or continue to maintain any Eurodollar Loans or to perform
its obligations as contemplated hereby, such Bank shall promptly give notice
thereof to the Borrower and such Bank's obligations to make or maintain
Eurodollar Loans under this Agreement shall terminate until it is no longer
unlawful for such Bank to make or maintain Eurodollar Loans.  The Borrower
shall prepay on demand the outstanding principal amount of any such affected
Eurodollar Loans, together with all interest accrued thereon and all other
amounts then due and payable to such Bank under this Agreement; provided,
however, subject to all of the terms and conditions of this Agreement, the
Borrower may then elect to borrow the principal amount of the affected
Eurodollar Loans from such Bank by means of Base Rate Loans from such Bank,
which Base Rate Loans shall not be made ratably by the Banks but only from such
affected Bank.

          Section 10.2.     Unavailability of Deposits or Inability to
Ascertain, or Inadequacy of, LIBOR.  If on or prior to the first day of any
Interest Period for any Borrowing of Eurodollar Loans:




                                    -53-

<PAGE>   59

                  (a)     the Agent determines that deposits in U.S. Dollars
         (in the applicable amounts) are not being offered to it in the
         interbank eurodollar market for such Interest Period, or that by
         reason of circumstances affecting the interbank eurodollar market
         adequate and reasonable means do not exist for ascertaining the
         applicable LIBOR, or

                  (b)     the Required Banks advise the Agent that (i) LIBOR as
         determined by the Agent will not adequately and fairly reflect the
         cost to such Banks of funding their Eurodollar Loans for such Interest
         Period or (ii) that the making or funding of Eurodollar Loans become
         impracticable,

then the Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks to
make Eurodollar Loans shall be suspended.

          Section 10.3.     Increased Cost and Reduced Return.  (a) If, on or
after the date hereof, the adoption of any applicable law, rule or regulation,
or any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
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:

                  (i)     shall subject any Bank (or its Lending Office) to any
         tax, duty or other charge with respect to its Eurodollar Loans or
         Fixed Rate Loans, its Notes, its Letter(s) of Credit, or its
         participation in any thereof, any Reimbursement Obligations owed to it
         or its obligation to make Eurodollar Loans or Fixed Rate Loans, issue
         a Letter of Credit, or to participate therein, or shall change the
         basis of taxation of payments to any Bank (or its Lending Office) of
         the principal of or interest on its Eurodollar Loans, Letter(s) of
         Credit, or participations therein or any other amounts due under this
         Agreement or any other Loan Document in respect of its Eurodollar
         Loans or Fixed Rate Loans, Letter(s) of Credit, any participation
         therein, any Reimbursement Obligations owed to it, or its obligation
         to make Eurodollar Loans or Fixed Rate Loans, or issue a Letter of
         Credit, or acquire participations therein (except for changes in the
         rate of tax on the overall net income of such Bank or its Lending
         Office imposed by the jurisdiction in which such Bank's principal
         executive office or Lending Office is located); or

                 (ii)     shall impose, modify or deem applicable any reserve,
         special deposit or similar requirement (including, without limitation,
         any such requirement imposed by the Board of Governors of the Federal
         Reserve System, but excluding with respect to any Eurodollar Loans or
         Fixed Rate Loans any such requirement included in an applicable
         Eurodollar Reserve Percentage) against assets of, deposits with or for
         the account of, or credit extended by, any Bank (or its Lending
         Office) or shall impose on any Bank (or its Lending Office) or on the
         interbank market any other condition affecting its Eurodollar Loans or
         Fixed Rate Loans, its Notes, its Letter(s) of Credit, or its
         participation in any thereof, any Reimbursement Obligation owed to it,
         or its obligation to make Eurodollar Loans or Fixed Rate Loans, or to
         issue a Letter of Credit, or to participate therein;






                                    -54-

<PAGE>   60

and the result of any of the foregoing is to increase the cost to such Bank (or
its Lending Office) of making or maintaining any Eurodollar Loan or Fixed Rate
Loan, issuing or maintaining a Letter of Credit, or participating therein, or
to reduce the amount of any sum received or receivable by such Bank (or its
Lending Office) under this Agreement or under any other Loan Document with
respect thereto, by an amount deemed by such Bank to be material, then, within
15 days after demand by such Bank (with a copy to the Agent), the Borrower
shall be obligated to pay to such Bank such additional amount or amounts as
will compensate such Bank for such increased cost or reduction.

          (b)    If, after the date hereof, any Bank or the Agent shall have
determined that the adoption of any applicable law, rule or regulation
regarding capital adequacy, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or its Lending Office) with any request or
directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has had the effect of
reducing the rate of return on such Bank's capital as a consequence of its
obligations hereunder to a level below that which such Bank could have achieved
but for such adoption, change or compliance (taking into consideration such
Bank's policies with respect to capital adequacy) by an amount deemed by such
Bank to be material, then from time to time, within 15 days after demand by
such Bank (with a copy to the Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank for such reduction.

          (c)    A certificate of a Bank claiming compensation under this
Section 9.3 and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive if reasonably determined.  In determining such
amount, such Bank may use any reasonable averaging and attribution methods.

          Section 10.4.     Lending Offices.  Each Bank may, at its option,
elect to make its Loans hereunder at the branch, office or affiliate specified
on the appropriate signature page hereof (each a "Lending Office") for each
type of Loan available hereunder or at such other of its branches, offices or
affiliates as it may from time to time elect and designate in a written notice
to the Borrower and the Agent.

          Section 10.5.     Discretion of Bank as to Manner of Funding.
Notwithstanding any other provision of this Agreement, each Bank shall be
entitled to fund and maintain its funding of all or any part of its Loans in
any manner it sees fit, it being understood, however, that for the purposes of
this Agreement all determinations hereunder with respect to Eurodollar Loans
shall be made as if each Bank had actually funded and maintained each
Eurodollar Loan through the purchase of deposits in the interbank eurodollar
market having a maturity corresponding to such Loan's Interest Period and
bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 11.    THE AGENT.

          Section 11.1.     Appointment and Authorization of Agent.  Each Bank
hereby appoints Bank of Montreal as the Agent under the Loan Documents and
hereby authorizes the Agent to take such action as Agent on its behalf and to
exercise such powers under the Loan Documents as are delegated to the Agent by
the terms thereof, together with such powers as are reasonably incidental
thereto.  The Banks expressly agree that the Agent is not acting as a fiduciary
of the Banks in respect of the Loan Documents, the Borrower or otherwise, and
nothing herein or in any of the other Loan Documents shall result in any duties
or obligations on the Agent or any of the Banks except as expressly set forth
herein.

          Section 11.2.     Agent and its Affiliates.  The Agent shall have the
same rights and powers under this Agreement and the other Loan Documents as any
other Bank and may exercise or refrain from exercising such rights and power as
though it were not the Agent, and the Agent and its affiliates may accept
deposits from, lend money to, and generally engage in any kind of business with
the Borrower or any Affiliate of the Borrower as if it were not the Agent under
the Loan Documents.  The term "Bank" as used herein and in all other Loan
Documents, unless the context otherwise clearly requires, includes the Agent in
its individual capacity as a Bank.  References in Section 1 hereof to the
Agent's Loans, or to the amount owing to the Agent for which an interest rate
is being determined, refer to the Agent in its individual capacity as a Bank.

          Section 11.3.     Action by Agent.  If the Agent receives from the
Borrower a written notice of an Event of Default pursuant to Section 8.5
hereof, the Agent shall promptly give each of the Banks written notice thereof.
The obligations of the Agent under the Loan Documents are only those expressly
set forth therein.  Without limiting the generality of the foregoing, the Agent
shall not be required to take any action hereunder with respect to any Default
or Event of Default, except as expressly provided in Sections 9.2 and 9.5.
Upon the occurrence of an Event of Default, the Agent shall take such action to
enforce its Lien on the Collateral and to preserve and protect the Collateral
as may be directed by the Required Banks.  Unless and until the Required Banks
give such direction, the Agent may (but shall not be obligated to) take or
refrain from taking such actions as it deems appropriate and in the best
interest of all the Banks.  In no event, however, shall the Agent be required
to take any action in violation of applicable law or of any provision of any
Loan Document, and the Agent shall in all cases be fully justified in failing
or refusing to act hereunder or under any other Loan Document unless it first
receives any further assurances of its indemnification from the Banks that it
may require, including prepayment of any related expenses and any other
protection it requires against any and all costs, expense, and liability which
may be incurred by it by reason of taking or continuing to take any such
action.  The Agent shall be entitled to assume that no Default or Event of
Default exists unless notified in writing to the contrary by a Bank or the
Borrower.  In all cases in which the Loan Documents do not require the Agent to
take specific action, the Agent shall be fully justified in using its
discretion in failing to take or in taking any action thereunder.  Any
instructions of the Required Banks, or of any other group of Banks called for
under the specific provisions of the Loan Documents, shall be binding upon all
the Banks and the holders of the Obligations.

<PAGE>   62

          Section 11.4.     Consultation with Experts.  The Agent 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 by it
in good faith in accordance with the advice of such counsel, accountants or
experts.

          Section 11.5.     Liability of Agent; Credit Decision.  Neither the
Agent nor any of its directors, officers, agents, or employees shall be liable
for any action taken or not taken by it in connection with the Loan Documents:
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct.  Neither the Agent
nor any of its directors, officers, agents or employees shall be responsible
for or have any duty to ascertain, inquire into or verify:  (i) any statement,
warranty or representation made in connection with this Agreement, any other
Loan Document or any Credit Event; (ii) the performance or observance of any of
the covenants or agreements of the Borrower or any Subsidiary contained herein
or in any other Loan Document; (iii) the satisfaction of any condition
specified in Section 7 hereof, except receipt of items required to be delivered
to the Agent; or (iv) the validity, effectiveness, genuineness, enforceability,
perfection, value, worth or collectibility hereof or of any other Loan Document
or of any other documents or writing furnished in connection with any Loan
Document or of any Collateral; and the Agent makes no representation of any
kind or character with respect to any such matter mentioned in this sentence. 
The Agent may execute any of its duties under any of the Loan Documents by or
through employees, agents, and attorneys-in-fact and shall not be answerable to
the Banks, the Borrower, or any other Person for the default or misconduct of
any such agents or attorneys-in-fact selected with reasonable care, except for
its gross negligence or willful misconduct.  The Agent shall not incur any
liability by acting in reliance upon any notice, consent, certificate, other
document or statement (whether written or oral) believed by it to be genuine or
to be sent by the proper party or parties.  In particular and without limiting
any of the foregoing, the Agent shall have no responsibility for confirming the
accuracy of any compliance certificate or other document or instrument received
by it under the Loan Documents.  The Agent may treat the payee of any Note as
the holder thereof until written notice of transfer shall have been filed with
the Agent signed by such payee in form satisfactory to the Agent.  Each Bank
acknowledges that it has independently and without reliance on the Agent or any
other Bank, and based upon such information, investigations and inquiries as it
deems appropriate, made its own credit analysis and decision to extend credit
to the Borrower in the manner set forth in the Loan Documents.  It shall be the
responsibility of each Bank to keep itself informed as to the creditworthiness
of the Borrower and its Subsidiaries, and the Agent shall have no liability to
any Bank with respect thereto.

          Section 11.6.     Indemnity.  The Banks shall ratably, in accordance
with their respective Percentages, indemnify and hold the Agent, and its
directors, officers, employees, agents and representatives harmless from and
against any liabilities, losses, costs or expenses suffered or incurred by it
under any Loan Document or in connection with the transactions contemplated
thereby, regardless of when asserted or arising, except to the extent they are
promptly reimbursed for the same by the Borrower and except to the extent that
any event giving rise to a claim was caused by the gross negligence or willful
misconduct of the party seeking to be indemnified.  The obligations of the
Banks under this Section shall survive termination of this Agreement.

<PAGE>   63

          Section 11.7.     Resignation of Agent and Successor Agent.  The
Agent may resign at any time by giving written notice thereof to the Banks and
the Borrower.  Upon any such resignation of the Agent, the Required Banks shall
have the right to appoint a successor Agent.  If no successor Agent shall have
been so appointed by the Required Banks, and shall have accepted such
appointment, within 30 days after the retiring Agent's giving of notice of
resignation then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be any Bank hereunder or any commercial bank
organized under the laws of the United States of America or of any State
thereof and having a combined capital and surplus of at least $200,000,000.
Upon the acceptance of its appointment as the Agent hereunder, such successor
Agent shall thereupon succeed to and become vested with all the rights and
duties of the retiring Agent under the Loan Documents, and the retiring Agent
shall be discharged from its duties and obligations thereunder.  After any
retiring Agent's resignation hereunder as Agent, the provisions of this Section
11 and all protective provisions of the other Loan Documents shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Agent. 

SECTION 12.            MISCELLANEOUS.

          Section 12.1.     Withholding Taxes.  (a) Payments Free of
Withholding.  Except as otherwise required by law and subject to Section
12.1(b) hereof, each payment by the Borrower under this Agreement or the other
Loan Documents shall be made without withholding for or on account of any
present or future taxes (other than overall net income taxes on the recipient)
imposed by or within the jurisdiction in which the Borrower is domiciled, any
jurisdiction from which the Borrower makes any payment, or (in each case) any
political subdivision or taxing authority thereof or therein.  If any such
withholding is so required, the Borrower shall make the withholding, pay the
amount withheld to the appropriate governmental authority before penalties
attach thereto or interest accrues thereon and forthwith pay such additional
amount as may be necessary to ensure that the net amount actually received by
each Bank and the Agent free and clear of such taxes (including such taxes on
such additional amount) is equal to the amount which that Bank or the Agent (as
the case may be) would have received had such withholding not been made.  If
the Agent or any Bank pays any amount in respect of any such taxes, penalties
or interest, the Borrower shall reimburse the Agent or such Bank for that
payment on demand in the currency in which such payment was made.  If the
Borrower pays any such taxes, penalties or interest, it shall deliver official
tax receipts evidencing that payment or certified copies thereof to the Bank or
Agent on whose account such withholding was made (with a copy to the Agent if
not the recipient of the original) on or before the thirtieth day after
payment.

          (b)    U.S. Withholding Tax Exemptions.  Each Bank that is not a
United States person (as such term is defined in Section 7701(a)(30) of the
Code) shall submit to the Borrower and the Agent on or before the earlier of
the date the initial Borrowing is made hereunder and 30 days after the date
hereof, two duly completed and signed copies of either Form 1001 (relating to
such Bank and entitling it to a complete exemption from withholding under the
Code on all amounts to be received by such Bank, including fees, pursuant to
the Loan Documents and the Loans) or Form 4224 (relating to all amounts to be
received by such Bank, including fees, pursuant to the Loan Documents and the
Loans) of the United States Internal 





                                    -58-

Revenue Service.  Thereafter and from time to time, each Bank shall submit to
the Borrower and the Agent such additional duly completed and signed copies of
one or the other of such Forms (or such successor forms as shall be adopted
from time to time by the relevant United States taxing authorities) as may be
(i) requested by the Borrower in a written notice, directly or through the
Agent, to such Bank and (ii) required under then-current United States law or
regulations to avoid or reduce United States withholding taxes on payments in
respect of all amounts to be received by such Bank, including fees, pursuant to
the Loan Documents or the Loans.

          (c)    Inability of Bank to Submit Forms.  If any Bank determines, as
a result of any change in applicable law, regulation or treaty, or in any
official application or interpretation thereof, that it is unable to submit to
the Borrower or the Agent any form or certificate that such Bank is obligated
to submit pursuant to subsection (b) of this Section 12.1 or that such Bank is
required to withdraw or cancel any such form or certificate previously
submitted or any such form or certificate otherwise becomes ineffective or
inaccurate, such Bank shall promptly notify the Borrower and Agent of such fact
and the Bank shall to that extent not be obligated to provide any such form or
certificate and will be entitled to withdraw or cancel any affected form or
certificate, as applicable.

          Section 12.2.     No Waiver, Cumulative Remedies.  No delay or
failure on the part of the Agent or any Bank or on the part of the holder or
holders of any of the Obligations in the exercise of any power or right under
any Loan Document shall operate as a waiver thereof or as an acquiescence in
any default, nor shall any single or partial exercise of any power or right
preclude any other or further exercise thereof or the exercise of any other
power or right.  The rights and remedies hereunder of the Agent, the Banks and
of the holder or holders of any of the Obligations are cumulative to, and not
exclusive of, any rights or remedies which any of them would otherwise have.

          Section 12.3.     Non-Business Days.  If any payment hereunder
becomes due and payable on a day which is not a Business Day, the due date of
such payment shall be extended to the next succeeding Business Day on which
date such payment shall be due and payable.  In the case of any payment of
principal falling due on a day which is not a Business Day, interest on such
principal amount shall continue to accrue during such extension at the rate per
annum then in effect, which accrued amount shall be due and payable on the next
scheduled date for the payment of interest.

          Section 12.4.     Documentary Taxes.  The Borrower agrees to pay on
demand any documentary, stamp or similar taxes payable in respect of this
Agreement or any other Loan Document, including interest and penalties, in the
event any such taxes are assessed, irrespective of when such assessment is made
and whether or not any credit is then in use or available hereunder.

          Section 12.5.     Survival of Representations.  All representations
and warranties made herein or in any other Loan Document or in certificates
given pursuant hereto or thereto shall survive the execution and delivery of
this Agreement and the other Loan Documents, and shall 




                                    -59-

<PAGE>   65

continue in full force and effect with respect to the date as of which they
were made as long as any credit is in use or available hereunder.

          Section 12.6.     Survival of Indemnities.  All indemnities and other
provisions relative to reimbursement to the Banks of amounts sufficient to
protect the yield of the Banks with respect to the Loans and Letters of Credit,
including, but not limited to, Sections 1.12, 10.3 and 12.15 hereof, shall
survive the termination of this Agreement and the other Loan Documents and the
payment of the Obligations.

          Section 12.7.     Sharing of Set-Off.  Each Bank agrees with each
other Bank a party hereto that if such Bank shall receive and retain any
payment, whether by set-off or application of deposit balances or otherwise, on
any of the Loans or Reimbursement Obligations in excess of its ratable share of
payments on all such Obligations then outstanding to the Banks, then such Bank
shall purchase for cash at face value, but without recourse, ratably from each
of the other Banks such amount of the Loans or Reimbursement Obligations, or
participations therein, held by each such other Banks (or interest therein) as
shall be necessary to cause such Bank to share such excess payment ratably with
all the other Banks; provided, however, that if any such purchase is made by
any Bank, and if such excess payment or part thereof is thereafter recovered
from such purchasing Bank, the related purchases from the other Banks shall be
rescinded ratably and the purchase price restored as to the portion of such
excess payment so recovered, but without interest.  For purposes of this
Section, amounts owed to or recovered by, the Agent in connection with
Reimbursement Obligations in which Banks have been required to fund their
participation shall be treated as amounts owed to or recovered by the Agent as
a Bank hereunder.

          Section 12.8.     Notices.  Except as otherwise specified herein, all
notices hereunder and under the other Loan Documents shall be in writing
(including, without limitation, notice by telecopy) and shall be given to the
relevant party at its address or telecopier number set forth below, or such
other address or telecopier number as such party may hereafter specify by
notice to the Agent and the Borrower given by courier, by United States
certified or registered mail, by telecopy or by other telecommunication device
capable of creating a written record of such notice and its receipt.  Notices
under the Loan Documents to the Banks and the Agent shall be addressed to their
respective addresses or telecopier numbers set forth on the signature pages
hereof, and to the Borrower to:

return receipt requested, addressed as aforesaid or (iii) if given by any other
means, when delivered at the addresses specified in this Section or on the
signature pages hereof; provided that any notice given pursuant to Section 1
hereof shall be effective only upon receipt.

          Section 12.9.     Counterparts.  This Agreement may be executed in
any number of counterparts, and by the different parties hereto on separate
counterpart signature pages, and all such counterparts taken together shall be
deemed to constitute one and the same instrument.

         Section 12.10.     Successors and Assigns.  This Agreement shall be
binding upon the Borrower and its successors and assigns, and shall inure to
the benefit of the Agent and each of the Banks and the benefit of their
respective successors and assigns, including any subsequent holder of any of
the Obligations.  The Borrower may not assign any of its rights or obligations
under any Loan Document without the written consent of all of the Banks.

        Section 12.11.      Participants.  Each Bank shall have the right at
its own cost to grant participations (to be evidenced by one or more agreements
or certificates of participation) in the Loans made and Reimbursement
Obligations and/or Commitments held by such Bank at any time and from time to
time to one or more other Persons; provided that no such participation shall
relieve any Bank of any of its obligations under this Agreement, and, provided,
further that no such participant shall have any rights under this Agreement
except as provided in this Section, and the Agent shall have no obligation or
responsibility to such participant.  Any agreement pursuant to which such
participation is granted shall provide that the granting Bank shall retain the
sole right and responsibility to enforce the obligations of the Borrower under
this Agreement and the other Loan Documents including, without limitation, the
right to approve any amendment, modification or waiver of any provision of the
Loan Documents, except that such agreement may provide that such Bank will not
agree to any modification, amendment or waiver of the Loan Documents that would
reduce the amount of or postpone any fixed date for payment of any Obligation
in which such participant has an interest.  Any party to which such a
participation has been granted shall have the benefits of Section 1.12 and
Section 10.3 hereof.  The Borrower authorizes each Bank to disclose to any




                                    -61-

<PAGE>   67

participant or prospective participant under this Section any financial or
other information pertaining to the Borrower.

         Section 12.12.     Assignment of Commitments by Banks.  Each Bank
shall have the right at any time, with the prior consent of the Agent and, so
long as no Event of Default then exists, the Borrower (which consent of the
Borrower shall not be unreasonably withheld-it being agreed that the Borrower's
consent shall not be required during the existence of any Event of Default), to
sell, assign, transfer or negotiate all or any part of its Commitments
(including the same percentage of its Notes, outstanding Loans and
Reimbursement Obligations owed to it) to one or more commercial banks or other
financial institutions, provided that such assignment shall be of a fixed
percentage (and not by its terms of varying percentage) of the assigning Bank's
Commitments; provided, however, that in order to make any such assignment (i)
unless the assignee Bank is assigning all of its Commitments, the assigning
Bank shall retain at least $5,000,000 in Commitments, (ii) the assignee bank
shall have Commitments of at least $5,000,000, (iii) each such assignment shall
be evidenced by a written agreement (substantially in the form attached hereto
as Exhibit H or in such other form acceptable to the Agent) executed by such
assigning Bank, such assignee bank or banks, the Agent and, if required as
provided above, the Borrower, which agreement shall specify in each instance
the portion of the Obligations which are to be assigned to the assignee bank
and the portion of the Commitments of the assigning Bank to be assumed by the
assignee bank or banks, and (iv) the assigning Bank shall pay to the Agent a
processing fee of $3,500 and any out-of-pocket attorneys' fees and expenses
incurred by the Agent in connection with any such assignment agreement.  Any
such assignee shall become a Bank for all purposes hereunder to the extent of
the Commitments it assumes and the assigning Bank shall be released from its
obligations, and will have released its rights, under the Loan Documents to the
extent of such assignment.  The Borrower authorizes each Bank to disclose to
any purchaser or prospective purchaser of an interest in the Loans and
Reimbursement Obligations owed to it or its Commitments under this Section any
financial or other information pertaining to the Borrower.

         Section 12.13.     Amendments.  Any provision of this Agreement or the
other Loan Documents may be amended or waived if, but only if, such amendment
or waiver is in writing and is signed by (a) the Borrower, (b) the Required
Banks, and (c) if the rights or duties of the Agent are affected thereby, the
Agent; provided that:

                  (i)     no amendment or waiver pursuant to this Section 12.13
         shall (A) increase any Commitment of any Bank without the consent of
         such Bank or (B) reduce the amount of or postpone the date for payment
         of any principal of or interest on any Loan or of any Reimbursement
         Obligation or of any fee payable hereunder without the consent of the
         Bank to which such payment is owing or which has committed to make
         such Loan or Letter of Credit (or participate therein) hereunder; and

                 (ii)     no amendment or waiver pursuant to this Section 12.13
         shall, unless signed by each Bank, change the definitions of Revolving
         Credit Termination Date, Term Credit Termination Date, Term Credit
         Final Maturity Date, or Required Banks, change the provisions of this
         Section 12.13, Section 7, Section 9, release any guarantor or all or
         any substantial part of the Collateral (except as otherwise provided
         for in the Loan

         Documents), or affect the number of Banks required to take any
         action hereunder or under any other Loan Document.  

         Section 12.14.     Headings.  Section headings used in this Agreement 
are for reference only and shall not affect the construction of this Agreement.

         Section 12.15.     Costs and Expenses.  The Borrower agrees to pay all
reasonable costs and out-of-pocket expenses of the Agent in connection with the
preparation, negotiation, and administration of the Loan Documents, including,
without limitation, the reasonable fees and disbursements of counsel to the
Agent, in connection with the preparation and execution of the Loan Documents,
and any amendment, waiver or consent related thereto, whether or not the
transactions contemplated herein are consummated.  The Borrower further agrees
to indemnify the Agent, each Bank, and their respective directors, officers and
employees, against all losses, claims, damages, penalties, judgments,
liabilities and expenses (including, without limitation, all reasonable
expenses of litigation or preparation therefor, whether or not the indemnified
Person is a party thereto) which any of them may pay or incur arising out of or
relating to any Loan Document or any of the transactions contemplated thereby
or the direct or indirect application or proposed application of the proceeds
of any Loan or Letter of Credit, other than those which arise from the gross
negligence or willful misconduct of the party claiming indemnification.  The
Borrower, upon demand by the Agent or a Bank at any time, shall reimburse the
Agent or such Bank for any legal or other expenses incurred in connection with
investigating or defending against any of the foregoing (including any
settlement costs relating to the foregoing) except if the same is directly due
to the gross negligence or willful misconduct of the party to be indemnified.
The obligations of the Borrower under this Section shall survive the
termination of this Agreement.

         Section 12.16.     Set-off.  In addition to any rights now or
hereafter granted under applicable law and not by way of limitation of any such
rights, upon the occurrence of any Event of Default, each Bank and each
subsequent holder of any Obligation is hereby authorized by the Borrower at any
time or from time to time, without notice to the Borrower or to any other
Person, any such notice being hereby expressly waived, to set-off and to
appropriate and to apply any and all deposits (general or special, including,
but not limited to, indebtedness evidenced by certificates of deposit, whether
matured or unmatured, but not including trust accounts, and in whatever
currency denominated) and any other indebtedness at any time held or owing by
that Bank or that subsequent holder to or for the credit or the account of the
Borrower, whether or not matured, against and on account of the Obligations of
the Borrower to that Bank or that subsequent holder under the Loan Documents,
including, but not limited to, all claims of any nature or description arising
out of or connected with the Loan Documents, irrespective of whether or not (a)
that Bank or that subsequent holder shall have made any demand hereunder or (b)
the principal of or the interest on the Loans or Notes and other amounts due
hereunder shall have become due and payable pursuant to Section 9 and although
said obligations and liabilities, or any of them, may be contingent or
unmatured.  Any Bank exercising any such right of set-off shall endeavor in
good faith to give the Borrower notice after effecting any such set-off;
however such Bank shall in no event be liable to the Borrower for such Bank's
failure to do so and its failure to do so shall not affect the validity of any
such set-off.

         Section 12.17.     Entire Agreement.  The Loan Documents constitute
the entire understanding of the parties thereto with respect to the subject
matter thereof and any prior agreements, whether written or oral, with respect
thereto are superseded hereby.

         Section 12.18.     Governing Law.  This Agreement and the other Loan
Documents, and the rights and duties of the parties hereto, shall be construed
and determined in accordance with the internal laws of the State of Illinois.

         Section 12.19.     Severability of Provisions.  Any provision of any
Loan Document which is unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

         Section 12.20.     Excess Interest.  Notwithstanding any provision to
the contrary contained herein or in any other Loan Document, no such provision
shall require the payment or permit the collection of any amount in excess of
the maximum amount of interest permitted by applicable law to be charged for
the use or detention, or the forbearance in the collection, of all or any
portion of the Loans or other obligations outstanding under this Agreement or
any other Loan Document ("Excess Interest").  If any Excess Interest is
provided for, or is adjudicated to be provided for, herein or in any other Loan
Document, then in such event (a) the provisions of this Section 12.20 shall
govern and control; (b) neither the Borrower nor any guarantor or endorser
shall be obligated to pay any Excess Interest; (c) any Excess Interest that the
Agent or any Bank may have received hereunder shall, at the option of the
Agent, be (i) applied as a credit against the then outstanding principal amount
of Loans hereunder, accrued and unpaid interest thereon (not to exceed the
maximum amount permitted by applicable law) and any other obligations, or all
of the foregoing; (ii) refunded to the Borrower, or (iii) any combination of
the foregoing; (d) the interest rate payable hereunder or under any other Loan
Document shall be automatically subject to reduction to the maximum lawful
contract rate allowed under applicable usury laws, and this Agreement and the
other Loan Documents shall be deemed to have been, and shall be, reformed and
modified to reflect such reduction in the relevant interest rate; and (e)
neither the Borrower nor any guarantor or endorser shall have any action
against the Agent or any Bank for any damages whatsoever arising out of the
payment or collection of any Excess Interest.

         Section 12.21.     Confidentiality.  Any information disclosed by the
Borrower or any of its Subsidiaries to the Agent or any Bank which was
designated proprietary or confidential at the time of its receipt by the Agent
or such Bank, and which it is not otherwise in the public domain, shall not be
disclosed by the Agent or such Bank to any other Person except (i) to its
independent accountants and legal counsel (it being understood that the Persons
to whom such disclosure is made will be informed of the confidential nature of
such information and instructed to keep such information confidential), (ii)
pursuant to statutory and regulatory requirements, (iii) pursuant to any
mandatory court order, subpoena or other legal process, (iv) to the Agent or
any other Bank, (v) pursuant to any agreement heretofore or hereafter made
between such Bank and the Borrower which permits such disclosure, (vi) in
connection with the exercise of any remedy under the Loan Documents, or (vii)
subject to an agreement 




                                    -64-

<PAGE>   70

containing provisions substantially the same as those of this Section, to any
participant in or assignee of, or prospective participant in or assignee of,
any Obligation or Commitments.

         Section 12.22.     Single Bank.  If and so long as Bank of Montreal is
the only Bank hereunder, Bank of Montreal shall have all rights, powers and
privileges afforded to the Agent, the Banks, and the Required Banks hereunder
and under the other Loan Documents.

         Section 12.23.     Submission to Jurisdiction; Waiver of Jury Trial.
The Borrower hereby submits to the nonexclusive jurisdiction of the United
States District Court for the Northern District of Illinois and of any Illinois
State court sitting in the City of Chicago for purposes of all legal
proceedings arising out of or relating to this Agreement, the other Loan
Documents or the transactions contemplated hereby or thereby.  The Borrower
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such proceeding
brought in such a court and any claim that any such proceeding brought in such
a court has been brought in an inconvenient forum.  THE BORROWER, THE AGENT AND
EACH BANK HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED THEREBY.

         Reference is made to the Credit Agreement, dated as of January 30,
1998, among Vision Twenty-One, Inc., the Banks party thereto, and Bank of
Montreal, as Agent (the "Credit Agreement").  Capitalized terms used herein and

                           ASSIGNMENT AND ACCEPTANCE


                          Dated _____________, 19_____


         Reference is made to the Credit Agreement dated as of January 30, 1998
(the "Credit Agreement") among Vision Twenty-One, Inc., a Florida corporation,
the Banks (as defined in the Credit Agreement) and Bank of Montreal, as Agent
for the Banks (the "Agent").  Terms defined in the Credit Agreement are used
herein with the same meaning.

         _____________________________________________________ (the "Assignor")
and _________________________ (the "Assignee") agree as follows:

                   1.     The Assignor hereby sells and assigns to the
         Assignee, and the Assignee hereby purchases and assumes from the
         Assignor, a _______% interest in and to all of the Assignor's rights
         and obligations under the Credit Agreement as of the Effective Date (as
         defined below), including, without limitation, such percentage interest
         in the Assignor's Commitments as in effect on the Effective Date and
         the Loans, if any, owing to the Assignor on the Effective Date and the
         Assignor's Percentage of any outstanding L/C Obligations.

                   2.     The Assignor (i) represents and warrants that as of
         the date hereof (A) its Revolving Credit Commitment is $_____________
         and its Term Credit Commitment is $____________, (B) the aggregate
         outstanding principal amount of Loans made by it under the Credit
         Agreement that have not been repaid is $____________ ($_____________
         of Revolving Loans and $_____________ of Term Loans) and a description
         of the interest rates and interest periods of such Loans is attached
         as Schedule 1 hereto, and (C) the aggregate principal amount of
         Assignor's Percentage of outstanding L/C Obligations is $____________;
         (ii) represents and warrants that it is the legal and beneficial owner
         of the interest being assigned by it hereunder and that such interest
         is free and clear of any adverse claim, lien, or encumbrance of any
         kind; (iii) makes no representation or warranty and assumes no
         responsibility with respect to any statements, warranties or
         representations made in or in connection with the Credit Agreement or
         the execution, legality, validity, enforceability, genuineness,
         sufficiency or value of the Credit Agreement or any other instrument
         or document furnished pursuant thereto; and (iv) makes no
         representation or warranty and assumes no responsibility with respect
         to the financial condition of the Borrower or any Subsidiary or the
         performance or observance by the Borrower  or any Subsidiary of any of
         its obligations under the Credit Agreement or any other instrument or
         document furnished pursuant thereto.

                   3.     The Assignee (i) confirms that it has received a copy
         of the Credit Agreement, together with copies of the financial
         statements referred to in Section 6.5 thereof and such other documents
         and information as it has deemed appropriate to make its own credit
         analysis and decision to enter into this Assignment and Acceptance;




<PAGE>   87

         (ii) agrees that it will, independently and without reliance upon the
         Agent, the Assignor or any other Bank and based on such documents and
         information as it shall deem appropriate at the time, continue to make
         its own credit decisions in taking or not taking action under the
         Credit Agreement; (iii) appoints and authorizes the Agent to take such
         action as Agent on its behalf and to exercise such powers under the
         Credit Agreement as are delegated to the Agent by the terms thereof,
         together with such powers as are reasonably incidental thereto; (iv)
         agrees that it will perform in accordance with their terms all of the
         obligations which by the terms of the Credit Agreement are required to
         be performed by it as a Bank; and (v) specifies as its lending office
         (and address for notices) the offices set forth beneath its name on
         the signature pages hereof.

                   4.     As consideration for the assignment and sale
         contemplated in Section 1 hereof, the Assignee shall pay to the
         Assignor on the Effective Date in Federal funds an amount equal to
         $________________*.  It is understood that commitment and/or facility
         fees accrued to the Effective Date with respect to the interest
         assigned hereby are for the account of the Assignor and such fees
         accruing from and including the date hereof are for the account of the
         Assignee.  Each of the Assignor and the Assignee hereby agrees that if
         it receives any amount under the Credit Agreement which is for the
         account of the other party hereto, it shall receive the same for the
         account of such other party to the extent of such other party's
         interest therein and shall promptly pay the same to such other party.

                   5.     The effective date for this Assignment and Acceptance
         shall be _____________, 19___(the "Effective Date").  Following the
         execution of this Assignment and Acceptance, it will be delivered to
         the Agent for acceptance and recording by the Agent and, if required,
         the Borrower.

                   6.     Upon such acceptance and recording, as of the
         Effective Date, (i) the Assignee shall be a party to the Credit
         Agreement and, to the extent provided in this Assignment and
         Acceptance, have the rights and obligations of a Bank thereunder and
         (ii) the Assignor shall, to the extent provided in this Assignment and
         Acceptance, relinquish its rights and be released from its obligations
         under the Credit Agreement.

                   7.     Upon such acceptance and recording, from and after
         the Effective Date, the Agent shall make all payments under the Credit
         Agreement in respect of the interest assigned hereby (including,
         without limitation, all payments of principal, interest and commitment
         fees with respect thereto) to the Assignee.  The Assignor and Assignee
         shall make all appropriate adjustments in payments under the Credit 
         Agreement for periods prior to the Effective Date directly between 
         themselves.  



- -----------

* Amount should combine principal together with accrued interest and breakage
  compensation, if any, to be paid by the Assignee, net of any portion of any
  upfront fee to be paid by the Assignor to the Assignee. It may be preferable 
  in an appropriate case to specify these amounts generically or by formula 
  rather than as a fixed sum.

                   8.     In accordance with Section 12.12 of the Credit

         Agent prepare and cause the Borrower to execute and deliver to 
         the Assignee the relevant Notes payable to the Assignee in the amount

         Commitments after giving effect to this assignment.
