     CREDIT AGREEMENT, dated as of February 20, 1997, between:


(a)  SIGHT RESOURCE CORPORATION, a Delaware corporation (the "Borrower"); and


(b)  CREDITANSTALT CORPORATE FINANCE, INC., a Delaware corporation, (the
     "Lender").


                                   WITNESSETH:
                                   -----------


     WHEREAS, the Borrower has requested that the Lender make available to it
credit facilities of up to $10,000,000 in the aggregate upon the terms, and
subject to the conditions, set forth herein to refinance existing debt, finance
future acquisitions, provide ongoing working capital and for other general
corporate purposes permitted by this Agreement;


     WHEREAS, the Lender is willing to provide such financing to the Borrower
only upon the terms and subject to the conditions set forth herein;


     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the parties hereto hereby agree as follows:

     SECTION 1. DEFINITIONS

     1.1. DEFINED TERMS. As used in this Agreement, the following terms shall
have the following meanings:


     "ABR": for any day, a rate per annum (rounded upwards, if necessary, to the
next 1/16 of 1%) equal to the greater of (i) the Prime Rate in effect on such
day and (ii) the Federal Funds Effective Rate in effect on such day plus 1/2 of
1%. If for any reason the Lender shall have determined (which determination
shall be conclusive absent manifest error) that it is unable to ascertain the
Federal Funds Effective Rate for any reason, including the inability or failure
of the Lender to obtain sufficient quotations in accordance with the terms
thereof, the ABR shall be determined without regard to clause (ii) of the first
sentence of this definition, until the circumstances giving rise to such
inability no longer exist. Any change in the ABR due to a change in the Prime
Rate or Federal Funds Effective Rate shall be effective on the effective date of
such change in the Prime Rate or Federal Funds Effective Rate, respectively.


     "ABR LOANS": Loans the rate of interest applicable to which is based upon
the ABR.


     "AFFILIATE": as to any Person, any other Person (other than a Subsidiary)
which, directly or indirectly, is in control of, is controlled by, or is under
common control with, such Person. For purposes of this definition, "control" of
a Person means the power, directly or indirectly, either to (a) vote 5% or more
of the securities having ordinary voting power for the election of directors of
such Person or (b) direct or cause the direction of the management and policies
of such Person, whether by contract or otherwise.


                                       2

     "AGGREGATE OUTSTANDING EXTENSIONS OF CREDIT": at any time, an amount equal
to the aggregate principal amount of all Revolving Credit Loans made by the
Lender then outstanding.


     "AGREEMENT": this Credit Agreement, as amended, supplemented or otherwise
modified from time to time.


     "APPLICABLE MARGIN": for each Type of Loan outstanding under each Facility,

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

     1.25%              2.75%


     "ASSIGNEE": as defined in subsection 10.6(c).

     "AVAILABLE REVOLVING CREDIT COMMITMENT": an amount equal to the excess, if
any, of (a) the lesser of the Revolving Credit Commitment and the Loan Value of

Credit.

     "AVAILABLE TERM LOAN COMMITMENT:" an amount equal to the excess, if any, of

     replacement.

     (d) Any payments of the Loans and reductions of the Commitments made
pursuant to (i) subsection 4.5(b) shall be applied in inverse order of maturity
to the then outstanding installments of the Term Loan or (ii) subsection 4.5(c)
shall be applied, first, to the prepayment of the Term Loan (with such
prepayment being applied in inverse order of maturity to the then outstanding
installments thereof) and, second, to repay Revolving Credit Loans and reduce
the Revolving Credit Commitments. Unless the Borrower otherwise elects, the
application of prepayments made pursuant to this subsection 4.5 shall be made,
first, to ABR Loans and, SECOND, to Eurodollar Loans.

     4.6. PREPAYMENT PREMIUM. If, on or before the Conversion Date, the Borrower
prepays any portion of the Loans with the proceeds of a loan from another
lender, the Borrower shall pay to the Lender, on or before the date of such
prepayment, a prepayment premium of 1% on any outstanding obligations so repaid,
PROVIDED, HOWEVER, that such prepayment premium shall not be due and payable if
the Borrower prepays the Loans with the proceeds of a loan from another lender
(a) if the Lender fails to designate a different lending office under
circumstances described in subsection 4.16.


                                       23
<PAGE>   28

     4.7. Conversion and Continuation Options.
          -----------------------------------

     (a) The Borrower may elect from time to time to convert Eurodollar Loans to
ABR Loans by delivering to the Lender an irrevocable Notice of Borrowing by
10:00 A.M., New York City time, at least one Business Day prior to the requested
date of conversion; PROVIDED that any such conversion of Eurodollar Loans may
only be made on the last day of an Interest Period with respect thereto. The
Borrower may elect from time to time to convert ABR Loans to Eurodollar Loans by
delivering to the Lender an irrevocable Notice of Borrowing by 10:00 A.M., New
York City time, at least three Business Days prior to the requested conversion
date. Any such Notice of Borrowing with respect to a conversion to Eurodollar
Loans shall specify the length of the initial Interest Period or Interest
Periods therefor. All or any part of outstanding Eurodollar Loans and ABR Loans
may be converted as provided herein, PROVIDED that (i) no Loan may be converted
into a Eurodollar Loan when any Default or Event of Default has occurred and is
continuing and the Lender has determined that such a conversion is not
appropriate and (ii) no Loan may be converted into a Eurodollar Loan after the
date that is one month prior to the Termination Date (in the case of conversions
of Revolving Credit Loans) or the date of the final installment of principal of
the Term Loan.

     (b) Any Eurodollar Loans may be continued as such upon the expiration of
the then current Interest Period with respect thereto by the Borrower delivering
to the Lender an irrevocable Notice of Borrowing, in accordance with the
applicable provisions of the term "INTEREST PERIOD" set forth in subsection 1.1,
of the length of the next Interest Period to be applicable to such Loans,
PROVIDED that no Eurodollar Loan may be continued as such (i) when any Event of
Default has occurred and is continuing and the Lender has determined that such a
continuation is not appropriate or (ii) after the date that is one month prior
to the Termination Date (in the case of continuations of Revolving Credit Loans)
or the date of the final installment of principal of the Term Loan and PROVIDED,
FURTHER, that if the Borrower shall fail to give such notice or if such
continuation is not permitted such Loans shall be automatically converted to ABR
Loans on the last day of such then expiring Interest Period.

     4.8. MINIMUM AMOUNTS AND MAXIMUM NUMBER OF TRANCHES. All borrowings,
conversions and continuations of Eurodollar Loans hereunder and all selections
of Interest Periods hereunder shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, the aggregate principal
amount of the Eurodollar Loans comprising each Tranche shall be equal to
$500,000 or a whole multiple of $250,000 in excess thereof. In no event shall
there be more than 5 Tranches of Eurodollar Loans outstanding at any time.

     4.9. Interest Rates and Payment Dates.
          --------------------------------

     (a) Each Eurodollar Loan shall bear interest for each day during each
Interest Period with respect thereto at a rate per annum equal to the Eurodollar
Rate determined for such day plus the then Applicable Margin.

     (b) Each ABR Loan shall bear interest at a rate per annum equal to the ABR
plus the then Applicable Margin.


                                       24
<PAGE>   29

     (c) If all or a portion of (i) any principal of any Loan, (ii) any interest
payable thereon, (iii) any commitment fee or (iv) any other amount payable
hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), the principal of the Loans and any such overdue
interest, commitment fee or other amount shall bear interest at a rate per annum
which is (x) in the case of principal, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this subsection
4.9(c) plus 2% or (y) in the case of any such overdue interest, commitment fee
or other amount, the rate described in paragraph (b) of this subsection plus 2%,
in each case from the date of such non-payment until such overdue principal,
interest, commitment fee or other amount is paid in full (as well after as
before judgment).

     (d) Interest shall be payable in arrears on each Interest Payment Date,
PROVIDED that interest accruing pursuant to paragraph (c) of this subsection
shall be payable from time to time on demand.

     (e) Notwithstanding anything to the contrary contained herein, in no event
shall the Borrower be obligated to pay interest in excess of the maximum amount
which is chargeable under applicable law.

     4.10. Computation of Interest and Fees.
           --------------------------------

     (a) Commitment Fees and, whenever it is calculated on the basis of the ABR,
interest shall be calculated on the basis of a 365- (or 366-, as the case may
be) day year for the actual days elapsed; and, otherwise, interest shall be
calculated on the basis of a 360-day year for the actual days elapsed. The
Lender shall as soon as practicable notify the Borrower of each determination of
a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the ABR or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective.

     (b) Each determination of an interest rate by the Lender pursuant to any
provision of this Agreement shall be conclusive and binding on the Borrower in
the absence of manifest error. The Lender shall, at the request of the Borrower,
deliver to the Borrower a statement showing the quotations used by the Lender in
determining any interest rate pursuant to subsection 4.9(a).

     4.11. INABILITY TO DETERMINE INTEREST RATE. If prior to the first day of
any Interest Period:

     (a) the Lender shall have determined (which determination shall be
conclusive and binding upon the Borrower) that, by reason of circumstances
affecting the relevant market, adequate and reasonable means do not exist for
ascertaining the Eurodollar Rate for such Interest Period, or

     (b) the Lender shall have determined that the Eurodollar Rate determined
(which determination shall be conclusive and binding upon the Borrower) for such
Interest Period will not adequately and fairly reflect the cost to the Lender of
making or maintaining their affected Loans during such Interest Period,



                                       25
<PAGE>   30

the Lender shall give telecopy or telephonic notice thereof to the Borrower as
soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans
requested to be made on the first day of such Interest Period shall be made as
ABR Loans, (y) any Loans that were to have been converted on the first day of
such Interest Period to Eurodollar Loans shall be converted to or continued as
ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the
first day of such Interest Period, to ABR Loans. Until such notice has been
withdrawn by the Lender, no further Eurodollar Loans shall be made or continued
as such, nor shall the Borrower have the right to convert Loans to Eurodollar
Loans.

     4.12. ILLEGALITY. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for the Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of the
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert ABR Loans to Eurodollar Loans shall forthwith be canceled and (b) the
Lender's Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to ABR Loans on the respective last days of the then current
Interest Periods with respect to such Loans or within such earlier period as
required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to the Lender such amounts, if any, as may be
required pursuant to subsection 4.15.

     4.13. Requirements of Law.
           ------------------- 

     (a) If the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof or compliance by the Lender with any
request or directive (whether or not having the force of law) from any central
bank or other Governmental Authority made subsequent to the date hereof:

          (i) shall subject the Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Note or any Eurodollar Loan made by it, or
     change the basis of taxation of payments to the Lender in respect thereof
     (except for Non-Excluded Taxes covered by subsection 4.14 and changes in
     the rate of net income taxes or franchise taxes (imposed in lieu of net
     income taxes) of the Lender);

          (ii) shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of the Lender which is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or


          (iii) shall impose on the Lender any other condition;

and the result of any of the foregoing is to increase the cost to the Lender, by
an amount which the Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the 



                                       26
<PAGE>   31

Borrower shall promptly pay the Lender such additional amount or amounts as will
compensate the Lender for such increased cost or reduced amount receivable.

     (b) If the Lender shall have determined that the adoption of or any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by the Lender or any corporation controlling
the Lender with any request or directive regarding capital adequacy (whether or
not having the force of law, if compliance therewith is a customary banking
practice) from any Governmental Authority made subsequent to the date hereof
shall have the effect of reducing the rate of return on the Lender's or such
corporation's capital as a consequence of its obligations hereunder to a level
below that which such corporation could have achieved but for such adoption,
change or compliance (taking into consideration the Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
the Lender to be material, then from time to time, the Borrower shall promptly
pay to the Lender such additional amount or amounts as will compensate the
Lender for such reduction.

     (c) If the Lender becomes entitled to claim any additional amounts pursuant
to this subsection 4.13, it shall promptly notify the Borrower (with a copy to
the Lender) of the event by reason of which it has become so entitled. A
certificate as to any additional amounts payable pursuant to this subsection
4.13 submitted by the Lender to the Borrower (with a copy to the Lender) shall
be conclusive in the absence of manifest error. The agreements in this
subsection 4.13 shall survive the termination of this Agreement and the payment
of the Loans and all other amounts payable hereunder.

     4.14. Taxes.
           -----

     (a) All payments made by the Borrower under this Agreement and any Notes
shall be made free and clear of, and without deduction or withholding for or on
account of, any present or future income, stamp or other taxes, levies, imposts,
duties, charges, fees, deductions or withholdings, now or hereafter imposed,
levied, collected, withheld or assessed by any Governmental Authority, excluding
net income taxes and franchise taxes (imposed in lieu of net income taxes)
imposed on the Lender as a result of a present or former connection between the
Lender and the jurisdiction of the Governmental Authority imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Lender having executed, delivered or
performed its obligations or received a payment under, or enforced, this
Agreement or any Note). If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("NON-EXCLUDED TAXES") are required to
be withheld from any amounts payable to the Lender hereunder or under any Note,
the amounts so payable to the Lender shall be increased to the extent necessary
to yield to the Lender (after payment of all Non-Excluded Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement. Whenever any Non-Excluded Taxes are payable by the Borrower, as
promptly as possible thereafter the Borrower shall send to the Lender for its
own account a certified copy of an original official receipt received by the
Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded
Taxes when due to the appropriate taxing authority or fails to remit to the
Lender the required receipts or other required documentary evidence, the
Borrower shall indemnify the Lender for any incremental taxes, 



                                       27
<PAGE>   32

interest or penalties that may become payable by the Lender as a result of any
such failure. The agreements in this subsection 4.14 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

     (b) If the Lender shall receive a credit or refund from a taxing authority
with respect to, and actually resulting from, an amount of Non-Excluded Taxes
actually paid to or on behalf of the Lender by the Borrower (a "TAX CREDIT"),
the Lender shall promptly notify the Borrower of such Tax Credit. If such Tax
Credit is received by the Lender in the form of cash, the Lender shall promptly
pay to the Borrower the amount so received with respect to the Tax Credit. If
such Tax Credit is not received by the Lender in the form of cash, the Lender
shall pay the amount of such Tax Credit not later than the time prescribed by
applicable Law for filing the return (including extensions of time) for the
Lender's taxable period which includes the period in which the Lender receives
the economic benefit of such Tax Credit. In any event, the amount of any Tax
Credit payable by a Lender to the Borrower pursuant to this clause (c) shall not
exceed the actual amount of cash refunded to, or credits received and usable (in
accordance with the actual practices then in use by the Lender) by, the Lender
from a taxing authority. In determining the amount of any Tax Credit, a Lender
may use such apportionment and attribution rules as the Lender customarily
employs in allocating taxes among its various operations and income sources and
such determination shall be conclusive absent manifest error. The Borrower
further agrees promptly to return to a Lender the amount paid to the Borrower
with respect to a Tax Credit by the Lender if the Lender is required to repay,
or is determined to be ineligible for, a Tax Credit for such amount.
Notwithstanding anything to the contrary contained herein, the Borrower hereby
acknowledges and agrees that (i) the Lender shall not be obligated to provide
the Borrower with details of the tax position of the Lender and (ii) the
Borrower shall have no right to inspect any records (including tax returns) of
the Lender.

     4.15. INDEMNITY. The Borrower agrees to indemnify the Lender and to hold
the Lender harmless from any loss or expense which the Lender may sustain or
incur as a consequence of (a) default by the Borrower in making a borrowing of,
conversion into or continuation of Eurodollar Loans after the Borrower has given
a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by the Borrower in making any prepayment after the
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making of a prepayment of Eurodollar Loans on a day which
is not the last day of an Interest Period with respect thereto. Such
indemnification may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue, the Interest
Period that would have commenced on the date of such failure) in each case at
the applicable rate of interest for such Loans provided for herein (excluding,
however, the Applicable Margin included therein, if any) over (ii) the amount of
interest (as reasonably determined by the Lender) which would have accrued to
the Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank eurodollar market. This covenant
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.


                                       28
<PAGE>   33

     4.16. CHANGE OF LENDING OFFICE. The Lender agrees that if it makes any
demand for payment under subsection 4.13 or 4.14(a), or if any adoption or
change of the type described in subsection 4.12 shall occur with respect to it,
it will use reasonable efforts (consistent with its internal policy and legal
and regulatory restrictions and so long as such efforts would not be
disadvantageous to it, as determined in its good faith discretion) to designate
a different lending office if the making of such a designation would reduce or
obviate the need for the Borrower to make payments under subsection 4.13 or
4.14(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 4.12.

     SECTION 5. REPRESENTATIONS AND WARRANTIES

     To induce the Lender to enter into this Agreement and to make the Loans the
Borrower hereby represents and warrants to the Lender that:

     5.1. FINANCIAL CONDITION. The consolidated balance sheet of the Borrower
and its consolidated Subsidiaries as at December 30, 1995 and the related
consolidated statements of income and cash flows for the fiscal year ended on
such date, reported on by KPMG Peat Marwick LLP, copies of which have heretofore
been furnished to the Lender, are complete and correct and present fairly in all
material respects the consolidated financial condition of the Borrower and its
consolidated Subsidiaries as at such date, and the consolidated results of their
operations and their consolidated cash flows for the fiscal year then ended. The
unaudited consolidated balance sheet of the Borrower and its consolidated
Subsidiaries as at November 23, 1996 and the related unaudited consolidated
statements of income and of cash flows for the eleven-month period ended on such
date, certified by a Responsible Officer, copies of which have heretofore been
furnished to the Lender, are complete and correct and present fairly in all
material respects the consolidated financial condition of the Borrower and its
consolidated Subsidiaries as at such date, and the consolidated results of their
operations and their consolidated cash flows for the eleven-month period then
ended (subject to normal year-end audit adjustments and the absence of
footnotes). All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by such accountants or
Responsible Officer, as the case may be, and as disclosed therein). Neither the
Borrower nor any of its consolidated Subsidiaries had, at the date of the most
recent balance sheet referred to above, any material Guarantee Obligation,
contingent liability or liability for taxes, or any long-term lease or unusual
forward or long-term commitment, including, without limitation, any interest
rate or foreign currency swap or exchange transaction, which is not reflected in
the foregoing statements or in the notes thereto. Except (i) to the extent
permitted under this Agreement (ii) for the write down of specific Opthamalic
Excimer Lasers, owned by the Borrower or its Subsidiaries as of the date hereof,
in an aggregate amount of $2,500,000, as disclosed to the Lender prior to the
date hereof, or (iii) as otherwise separately disclosed to the Lender in writing
prior to the date hereof, there has been no sale, transfer or other disposition
by the Borrower or any of its consolidated Subsidiaries of any material part of
its business or property and except for the E.B. Brown Acquisition, no purchase
or other acquisition of any business or property (including any capital stock of
any other Person) material in relation to the consolidated financial condition
of the Borrower and its consolidated 



                                       29
<PAGE>   34

Subsidiaries at December 30, 1995 during the period from December 30, 1995 and
including the date hereof.

     5.2. NO CHANGE. Since December 30, 1995, there has been no development or
event which has had or could reasonably be expected to have a Material Adverse
Effect.

     5.3. DISCLOSURE. No information, schedule, exhibit or report or other
document furnished by the Borrower or any of its Subsidiaries to the Lender in
connection with the negotiation of this Agreement or any other Loan Document (or
pursuant to the terms hereof or thereof), as such information, schedule, exhibit
or report or other document has been amended, supplemented or superseded by any
other information, schedule, exhibit or report or other document later delivered
to the same parties receiving such information, schedule, exhibit or report or
other document, contained any material misstatement of fact or omitted to state
a material fact or any fact necessary to make the statements contained therein,
in light of the circumstances when made, not materially misleading.

     5.4. CORPORATE EXISTENCE; COMPLIANCE WITH LAW. Each of the Borrower and its
Subsidiaries (i) is duly organized, validly existing and (in the case of the
Borrower and its Subsidiaries) in good standing under the laws of the
jurisdiction of its organization, (ii) has the corporate power and authority,
and the legal right, to own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it is currently engaged,
(iii) in the case of the Borrower and its Subsidiaries, is duly qualified as a
foreign corporation and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of property or the conduct of its
business requires such qualification, except to the extent that all failures to
be so qualified could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect and (iv) is in compliance with all Requirements of Law
except to the extent that all failures to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

     5.5. CORPORATE POWER, AUTHORIZATION, ENFORCEABLE OBLIGATIONS. The Borrower
has the corporate power and authority, and the legal right, to make, deliver and
perform the Loan Documents to which it is a party and to borrow hereunder and
has taken all necessary corporate action to authorize the borrowings on the
terms and conditions of this Agreement and any Notes and to authorize the
execution, delivery and performance of the Loan Documents to which it is a
party. No consent or authorization of, filing with, notice to or other act by or
in respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of the Loan Documents to which the
Borrower is a party, except as required to comply with federal or state
securities law in connection with the Warrant Agreement for which such consents
authorizations, filings, notices, or other actions have been obtained or made.
This Agreement has been, and each other Loan Document to which it is a party
will be, duly executed and delivered on behalf of the Borrower. This Agreement
constitutes, and each other Loan Document to which it is a party when executed
and delivered will constitute, a legal, valid and binding obligation of the
Borrower enforceable against the Borrower in accordance with its terms, subject
to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws 



                                       30
<PAGE>   35

relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

     5.6. NO LEGAL BAR. The execution, delivery and performance of the Loan
Documents to which the Borrower is a party, the borrowings hereunder and the use
of the proceeds thereof will not violate any material Requirement of Law or
material Contractual Obligation of the Borrower or of any of its Subsidiaries
and will not result in, or require, the creation or imposition of any Lien on
any of its or their respective properties or revenues pursuant to any such
Requirement of Law or Contractual Obligation.

     5.7. NO MATERIAL LITIGATION. No litigation, investigation or proceeding of
or before any arbitrator or Governmental Authority is pending or, to the
knowledge of the Borrower, threatened by or against the Borrower or any of its
Subsidiaries or against any of its or their respective properties or revenues
(a) with respect to any of the Loan Documents or any of the transactions
contemplated hereby or thereby, or (b) which could reasonably be expected to
have a Material Adverse Effect.

     5.8. NO DEFAULT. Neither the Borrower nor any of its Subsidiaries is in
default under or with respect to any of its Contractual Obligations in any
respect which could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

     5.9. OWNERSHIP OF PROPERTY; LIENS. Each of the Borrower and its
Subsidiaries has good record and marketable title in fee simple to, or a valid
leasehold interest in, all its real property, and good title to, or a valid
leasehold interest in, all its other property, and none of such property is
subject to any Lien except as permitted by subsection 8.3.

     5.10. INTELLECTUAL PROPERTY. The Borrower and each of its Subsidiaries
owns, or is licensed to use, all trademarks, trade names, copyrights,
technology, know-how and processes necessary for the conduct of its business as
currently conducted, except for those the failure to own or license which could
not reasonably be expected to have a Material Adverse Effect (the "INTELLECTUAL
PROPERTY"). No claim has been asserted and is pending by any Person challenging
or questioning the use of any such Intellectual Property or the validity or
effectiveness of any such Intellectual Property which, if accurate, could
reasonably be expected to have a Material Adverse Effect, nor does the Borrower
know of any valid basis for any such claim. To the best knowledge of the
Borrower, the use of such Intellectual Property by the Borrower and its
Subsidiaries does not infringe on the rights of any Person, except for such
claims and infringements that, in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

     5.11. NO BURDENSOME RESTRICTIONS. No Requirement of Law applicable to the
Borrower or any of its Subsidiaries could reasonably be expected to have a
Material Adverse Effect.

     5.12. TAXES. Each of the Borrower and its Subsidiaries has filed or caused
to be filed all tax returns which, to the knowledge of the Borrower, are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of 



                                       31
<PAGE>   36

its property and all other taxes, fees or other charges imposed on it or any of
its property by any Governmental Authority (other than any the amount or
validity of which are currently being contested in good faith by appropriate
proceedings and with respect to which reserves in conformity with GAAP have been
provided on the books of the Borrower or its Subsidiaries, as the case may be);
no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is
being asserted, with respect to any such tax, fee or other charge.

     5.13. FEDERAL REGULATIONS. No part of the proceeds of any Loans will be
used in any manner which would violate, or result in the violation of,
Regulation D, Regulation G or Regulation U of the Board of Governors of the
Federal Reserve System as now and from time to time hereafter in effect. If
requested by the Lender, the Borrower will furnish to the Lender a statement to
the foregoing effect in conformity with the requirements of FR Form G-3 or FR
Form U-1 referred to in said Regulation G or Regulation U, as the case may be.

     5.14. ERISA. Neither a Reportable Event nor an "accumulated funding
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen, during such five-year period. The
present value of all accrued benefits under each Single Employer Plan (based on
those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits. Neither the Borrower nor any Commonly Controlled Entity has had a
complete or partial withdrawal from any Multiemployer Plan, and neither the
Borrower nor any Commonly Controlled Entity would become subject to any
liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent. The
present value (determined using actuarial and other assumptions which are
reasonable in respect of the benefits provided and the employees participating)
of the liability of the Borrower and each Commonly Controlled Entity for post
retirement benefits to be provided to their current and former employees under

the Lender with respect to indemnified liabilities to the extent arising from
the gross negligence or willful misconduct of the Lender. The agreements in this
subsection 10.5 shall survive repayment of the Loans and all other amounts
payable hereunder.

     10.6. Successors and Assigns; Participations and Assignments.
           ------------------------------------------------------

     (a) This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lender, and their respective successors and assigns, except that
the Borrower may not assign or transfer any of its rights or obligations under
this Agreement without the prior written consent of the Lender.

     (b) The Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other financial institutions ("PARTICIPANTS") participating interests
in any Loan owing to the Lender, any Commitment of the Lender or any other
interest of the Lender hereunder and under the other Loan Documents. In the
event of any such sale by the Lender of a participating interest to a
Participant, the Lender's obligations under this Agreement shall remain
unchanged, the Lender shall remain solely responsible for the performance
thereof, the Lender shall remain the holder of any such Loan for all purposes
under this Agreement and the other Loan Documents, and the Borrower shall
continue to deal solely and directly with the Lender in connection with the
Lender's rights and obligations under this Agreement and the other Loan
Documents. The Lender shall not be entitled to create in favor of any
Participant, in the participation agreement pursuant to which such Participant's
participating interest shall be created or otherwise, any right to vote on,
consent to or approve any matter relating to this Agreement or any other Loan
Document. The Borrower agrees that if amounts outstanding under this Agreement
are due or unpaid, or shall have been declared or shall have become due and
payable upon the occurrence of an Event of Default, each Participant shall, to
the maximum extent permitted by applicable law, be deemed to have the right of
setoff in respect of its participating interest in amounts owing under this
Agreement to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under this Agreement, PROVIDED that, in
purchasing such participating interest, such 



                                       57
<PAGE>   62

Participant shall be deemed to have agreed to share with the Lender the proceeds
thereof as fully as if it were a Lender hereunder. The Borrower also agrees that
each Participant shall be entitled to the benefits of subsections 4.13, 4.14 and
4.15 with respect to its participation in the Commitments and the Loans
outstanding from time to time as if it was a Lender; PROVIDED that, in the case
of subsection 4.14, such Participant shall have complied with the requirements
of said subsection and PROVIDED, FURTHER, that no Participant shall be entitled
to receive any greater amount pursuant to any such subsection than the Lender
would have been entitled to receive in respect of the amount of the
participation transferred by the Lender to such Participant had no such transfer
occurred.

     (c) The Lender may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time and from time to
time assign to any affiliate of the Lender or, with the consent of the Borrower
(which in each case shall not be unreasonably withheld), to an additional bank
or financial institution (an "ASSIGNEE") all or any part of its rights and
obligations under this Agreement and the other Loan Documents pursuant to an
Assignment and Acceptance, in form and substance acceptable to the Lender,
executed by such Assignee, (and, in the case of an Assignee that is not an
affiliate thereof, by the Borrower) and delivered to the Lender for its
acceptance and recording, PROVIDED that, in the case of any such assignment to
an additional bank or financial institution, (x) the sum of the aggregate
principal amount of the Term Loan (or, prior to the Closing Date, Term Loan
Commitment) and the aggregate amount of the Revolving Credit Commitment being
assigned are not less than $1,000,000 (or such lesser amount as may be agreed to
by the Borrower and the Lender) and (y) if such assignment is of less than all
of the rights and obligations of the Lender, the sum of the aggregate principal
amount of the Term Loan (or, prior to the Closing Date, Term Loan Commitment)
and the aggregate amount of the Revolving Credit Commitment remaining with the
Lender is not less than 20% of the sum of the Term Loans then outstanding and
the Revolving Credit Commitments (or Aggregate Outstanding Extensions of Credit,
as the case may be) then in effect (or such lesser amount as may be agreed to by
the Borrower and the Lender). Upon such execution, delivery, acceptance and
recording (and the payment of the registration and processing fee described in
clause (e) below), from and after the effective date determined pursuant to such
Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto
and, to the extent PROVIDED in such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder with a Commitment as set forth therein,
and (y) the Lender thereunder shall, to the extent PROVIDED in such Assignment
and Acceptance, be released from its obligations under this Agreement (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of the Lender's rights and obligations under this Agreement, such assigning
Lender shall cease to be a party hereto). Notwithstanding any provision of this
paragraph (c) of this subsection, the consent of the Borrower shall not be
required for any assignment which occurs at any time when any of the events
described in subsection 9(f) shall have occurred and be continuing.

     (d) The Borrower authorizes the Lender to disclose to any Participant or
Assignee (each, a "TRANSFEREE") and any prospective Transferee any and all
financial information in the Lender's possession concerning the Borrower and its
Affiliates which has been delivered to the Lender by or on behalf of the
Borrower pursuant to this Agreement or which has been delivered 



                                       58
<PAGE>   63

to the Lender by or on behalf of the Borrower in connection with the Lender's
credit evaluation of the Borrower and its Affiliates prior to becoming a party
to this Agreement.

     (e) For avoidance of doubt, the parties to this Agreement acknowledge that
the provisions of this subsection 10.6 concerning assignments of Loans and Notes
relate only to absolute assignments and that such provisions do not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by the Lender of any Loan or Note to any Federal Reserve
Bank in accordance with applicable law.

     10.7. COUNTERPARTS. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts (including by
facsimile transmission), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Borrower and the
Lender.

     10.8. SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     10.9. INTEGRATION. This Agreement and the other Loan Documents represent
the agreement of the Borrower, and the Lender with respect to the subject matter
hereof, and there are no promises, undertakings, representations or warranties
by the Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Loan Documents.

     10.10. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     10.11. SUBMISSION TO JURISDICTION; WAIVERS. The Borrower hereby irrevocably
and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding
relating to this Agreement and the other Loan Documents to which it is a party,
or for recognition and enforcement of any judgment in respect thereof, to the
non-exclusive general jurisdiction of the Courts of the State of New York, the
courts of the United States of America for the Southern District of New York,
and appellate courts from any thereof,

     (b) consents that any such action or proceeding may be brought in such
courts and waives any objection that it may now or hereafter have to the venue
of any such action or proceeding in any such court or that such action or

     Process rinsewater used in the predecessor to Cambridge Eye Associate,
Inc.'s lens grinding operations was previously discharged to an on-site septic
tank after passing through a settling tank and a centrifuge designed to remove
particles of plastic and/or glass which were generated in the grinding process.
Such a process, in the absence of a groundwater discharge permit issued by the
Department of Environmental Protection, may have been in violation of the
Department's regulations 310 C.M.R. 15.8(2) and 314 C.M.R. 5, and M.G.L. c. 21,
ss.43. Cambridge Eye Associates has eliminated this process from its operations
and is informed and believes, that it is not currently in violation of any law,
rule or regulation.

deliver to Lender or, at the option of Lender, an Affiliate thereof, on the

     Section 3. REPRESENTATIONS AND WARRANTIES. The Issuer hereby represents and
warrants to Lender, for the benefit of Lender and any other Warrant Holder, as
follows:

     (a) The Issuer is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware, has the corporate power
and authority to conduct its business as presently conducted and as intended to
be conducted, has the corporate power and authority to execute and deliver this
Warrant Agreement and the Warrant Certificates, to issue the Warrants and to
perform its obligations under this Warrant Agreement and the Warrant
Certificates, has the corporate power and authority and legal right to own and
lease its properties and is duly qualified and in good standing as a foreign
corporation in each jurisdiction in which it owns or leases real property or in
which the conduct of its business requires such qualification, except where

adverse effect on the business, properties, financial condition or results of
operations of the Issuer and its Subsidiaries taken as a whole.


     (b) The execution, delivery and performance by the Issuer of this Warrant
Agreement and the Warrant Certificates, the issuance of the Warrants and the
issuance of the Warrant Shares upon the exercise of the Warrants have been duly
authorized by all necessary corporate action and do not and will not violate, or
result in a breach of, or constitute a default under, or require any consent
under, or result in the creation of any lien, charge or encumbrance upon the
assets of the Issuer pursuant to, any law, statute, ordinance, rule, regulation,
order or decree of any court, governmental body or regulatory authority or
administrative agency having jurisdiction over the Issuer or its Subsidiaries or
the Issuer's Articles of Incorporation or any contract, mortgage, loan
agreement, note, lease or other instrument binding upon the Issuer or its
Subsidiaries or by which their properties are bound.


     (c) This Warrant Agreement has been duly executed and delivered by the
Issuer and constitutes a legal, valid, binding and enforceable obligation of the
Issuer. When the Warrants and Warrant Certificates have been issued as
contemplated hereby, (i) the Warrants and the Warrant Certificates will

(ii) the Warrant Shares, when issued upon exercise of the Warrants in accordance
with the terms hereof will be duly authorized, validly issued, fully paid and
nonassessable shares of the Common Stock with no personal liability attaching to
the ownership thereof.


     (d) The Issuer has authorized capital stock consisting of 20,000,000 shares
of Common Stock, par value $.01 per share, of which 8,648,768 shares are issued
and outstanding and 5,000,000 shares of undesignated preferred stock, par value
$.01 per share, of which no shares are issued and outstanding. To the Issuer's
best knowledge, there are no voting

agreements, voting trusts, proxies or other agreements or understandings with
respect to the voting of any capital stock of the Issuer or any Subsidiary.


     Section 4. REGISTRATION, TRANSFER AND EXCHANGE OF CERTIFICATES.


     (a) The Issuer shall maintain, at the Warrant Office, the Warrant Register
for registration of the Warrants and Warrant Certificates and transfers thereof.
On the Closing Date, the Issuer shall register the Warrants and Warrant
Certificates in the Warrant Register in the name of Lender or an Affiliate
thereof, as the case may be. The Issuer may deem and treat the registered
holders of the Warrant Certificates as the absolute owners thereof and the
Warrants represented thereby (notwithstanding any notation of ownership or other
writing on the Warrant Certificates made by any person) for the purpose of any
exercise thereof or any distribution to the holders thereof, and for all other
purposes, and the Issuer shall not be affected by any notice to the contrary.


     (b) Subject to Section 14, the Issuer shall register the transfer of any
outstanding Warrants in the Warrant Register upon surrender of the Warrant
Certificates evidencing such Warrants to the Issuer at the Warrant Office,
accompanied (if so required by it) by a written instrument or instruments of
transfer in form satisfactory to it, duly executed by the registered holder or
holders thereof or by the duly appointed legal representative thereof. Upon any
such registration of transfer, new Warrant Certificates evidencing such
transferred Warrants shall be issued to the transferee and the surrendered
Warrant Certificates shall be canceled. If less than all the Warrants evidenced
by Warrant Certificates surrendered for transfer are to be transferred, new
Warrant Certificates shall be issued to the holder surrendering such Warrant
Certificates evidencing such remaining number of Warrants.


     (c) Warrant Certificates may be exchanged at the option of the holders
thereof, when surrendered to the Issuer at the Warrant Office, for another
Warrant Certificate or other Warrant Certificates of like tenor and representing
in the aggregate a like number of Warrants. Warrant Certificates surrendered for
exchange shall be canceled.


     (d) No charge shall be made for any such transfer or exchange except for
any tax or other governmental charge imposed in connection therewith. Except as
provided in subsection 14(b) each Warrant Certificate issued upon transfer or
exchange shall bear the legend set forth in subsection 14(b) if the Warrant
Certificate presented for transfer or exchange bore such legend.


     Section 5. MUTILATED OR MISSING WARRANT CERTIFICATES. If any Warrant
Certificate shall be mutilated, lost, stolen or destroyed, the Issuer shall
issue, in exchange and substitution for and upon cancellation of the mutilated
Warrant Certificate, or in lieu of and substitution for the Warrant Certificate
lost, stolen or destroyed, a new Warrant Certificate of like tenor and
representing an equivalent number of Warrants, but only upon receipt of evidence
satisfactory to the Issuer of such loss, theft or destruction of such Warrant
Certificate and, if requested, indemnity satisfactory to it. The Issuer
acknowledges that a written indemnity by Lender or, if an Affiliate of Lender is
the holder of such lost, stolen or destroyed Warrant Certificate, by such


                                       6
<PAGE>   7


Affiliate shall be satisfactory to the Issuer for such purpose. No service
charge shall be made for any such substitution, but all expenses and reasonable
charges associated with procuring such indemnity and all stamp, tax and other
governmental duties that may be imposed in relation thereto shall be borne by
the holder of such Warrant Certificate. Each Warrant Certificate issued in any
such substitution shall bear the legend set forth in subsection 14(b) if the
Warrant Certificate for which such substitution was made bore such legend.


     Section 6. DURATION AND EXERCISE OF WARRANTS.


     (a) The Warrants evidenced by a Warrant Certificate shall be exercisable in
whole or in part by the registered holder thereof on any Business Day after the
Closing Date and on or before 5:00 P.M., New York time, on the Expiration Date.


     (b) Subject to the provisions of this Warrant Agreement, the Warrants
evidenced by a Warrant Certificate may be exercised by the registered holder
thereof by the surrender of the Warrant Certificate evidencing the Warrants to
be exercised, with the form of election to purchase on the reverse thereof or
attached thereto duly completed and signed, to the Issuer at the Warrant Office,
and upon payment of the aggregate Exercise Price for the number of Warrant
Shares in respect of which such Warrants are being exercised in lawful money of
the United States of America and/or by surrender to the Issuer of shares of
Common Stock then owned by the Warrant Holder and valued for purposes hereof at
their Current Market Price Per Share at the time of exercise. In lieu of
exercising Warrants pursuant to the immediately preceding sentence, the Warrant
Holder shall have the right to require the Issuer to convert the Warrants, in
whole or in part and at any time or times (the "Conversion Right"), into Warrant
Shares, by surrendering to the Issuer the Warrant Certificate evidencing the
Warrants to be converted, accompanied by the form of conversion notice on the
reverse thereof or attached thereto which has been duly completed and signed.
Upon exercise of the Conversion Right, the Issuer shall deliver to the Warrant
Holder (without payment by the Warrant Holder of any Exercise Price) that number
of Warrant Shares which is equal to the quotient obtained by dividing (x) the
value of the number of Warrants being converted at the time the Conversion Right
is exercised (determined by subtracting the aggregate Exercise Price for all
such Warrants immediately prior to the exercise of the Conversion Right from the
aggregate current market price (determined on the basis of the Current Market
Price Per Share) of that number of Warrant Shares purchasable upon exercise of
such Warrants immediately prior to the exercise of the Conversion Right (taking
into account all applicable adjustments pursuant to Section 12 by (y) the
Current Market Price Per Share of one share of Common Stock immediately prior to
the exercise of the Conversion Right. Any references in this Warrant Agreement
to the "exercise" of any Warrants, and the use of the term "exercise" herein,
shall be deemed to include (without limitation) any exercise of the Conversion
Right. Any exercise of a Warrant hereunder may be made subject to the
satisfaction of one or more conditions (including, without limitation, the
consummation of a sale of the capital stock of the Issuer or a merger or other
business combination involving the Issuer) which are set forth in a writing
which is made a part of or is appended to the aforementioned form of election to
purchase or conversion notice (as the case may be) by the Warrant Holder.


                                       7
<PAGE>   8


     (c) Upon exercise of any Warrants hereunder, the Issuer shall issue and
cause to be delivered to or upon the written order of the registered holders of
such Warrants and in such name or names as such registered holders may
designate, a certificate for the Warrant Share or Warrant Shares issued upon
such exercise of such Warrants. Any Persons so designated to be named therein
shall be deemed to have become holders of record of such Warrant Share or
Warrant Shares as of the date of exercise of such Warrants.


     (d) If less than all of the Warrants evidenced by a Warrant Certificate are
exercised at any time, a new Warrant Certificate or Certificates shall be issued
for the remaining number of Warrants evidenced by such Warrant Certificate. Each
new Warrant Certificate so issued shall bear the legend set forth in subsection
14(b) if the Warrant Certificate presented in connection with partial exercise
thereof bore such legend unless the transfer restrictions referred to in such
legend are no longer applicable pursuant to subsection 14(d). All Warrant
Certificates surrendered upon exercise of Warrants shall be canceled.


     (e) A Warrant Holder shall not have the right to have issued to it upon
exercise Common Stock which, when aggregated with the shares of Common Stock
(other than shares of Non-Attributable Stock) previously issued as Warrant
Shares will exceed 4.99 % of the then outstanding Common Stock unless such
Warrant Holder certifies that such Warrants have previously been transferred
either (i) in a widely dispersed public offering of the Warrants, or (ii) in a
private placement in which no purchaser, individually or in concert with others,
would have acquired more than 2% of the outstanding Common Stock if the Warrants
so transferred had been exercised for Common Stock, or (iii) in compliance with
Rule 144 (or any rule which is a successor thereto) of the Securities Act, or
(iv) into the secondary market in a market transaction executed through a
registered broker-dealer in blocks of no more than 2% of the shares outstanding
of the Issuer in any six month period. In the event two or more Warrant Holders
attempt to exercise Warrants for Common Stock simultaneously and, if permitted,
such exercises would cause the 4.99% limitation to be exceeded, then the Issuer
shall notify the Warrant Holders who had attempted to exercise Warrants for
Common Stock and each such Warrant Holder shall be entitled to exercise for
Common Stock only such number of Warrants as shall equal the product of (i) the
number of Warrants the Warrant Holder sought to exercise for Common Stock times
(ii) a fraction, the numerator of which is the maximum number of Warrants which
may be exercised for Common Stock without exceeding the 4.99% limitation and the
denominator of which is the maximum number of Warrants sought to be exercised
for Common Stock by such Warrant Holders.


     (f) Notwithstanding the foregoing provisions of this Section 6, in no event
shall any Warrant be exercisable for shares of Common Stock which, when
aggregated with all other Warrant Shares then held by Lender or its Affiliates,
would, upon issuance, represent in excess of 24.99% of the Equity of the Issuer
unless such shares, when issued, would constitute Non-Attributable Stock.


     Section 7. NO FRACTIONAL SHARES. The Issuer shall not be required to issue
fractional shares of Common Stock upon exercise of the Warrants but shall pay
for any such fraction of a 


                                       8
<PAGE>   9


share an amount in cash equal to the then Current Market Price Per Share of one
share of Common Stock multiplied by such fraction.


     Section 8. PAYMENT OF TAXES. The Issuer will pay all taxes attributable to
the initial issuance of Warrant Shares upon the exercise of the Warrants,
provided that the Issuer shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issue of any Warrant
Certificate or any certificate for Warrant Shares in a name other than that of
the registered holder of a Warrant Certificate surrendered upon the exercise of
a Warrant, and the Issuer shall not be required to issue or deliver such
certificate unless or until the person or persons requesting the issuance
thereof shall have paid to the Issuer the amount of such tax or shall have
established to the satisfaction of the Issuer that such tax has been paid.


     Section 9. STOCKHOLDER RIGHTS.


     (a) Nothing contained in this Warrant Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the holders thereof the right
to vote or to consent or to receive notice as a stockholder in respect of the
meetings of stockholders or the election of directors of the Issuer or any other
matter, or any rights whatsoever as a stockholder of the Issuer.


     (b) Nothing contained in this Warrant Agreement or in any of the Warrant
Certificates shall be construed as imposing any obligation on the registered
holders thereof to purchase any securities or as imposing any liabilities on
such holders as stockholders of the Issuer, whether such obligation or
liabilities are asserted by the Issuer or by creditors of the Issuer.


     Section 10. RESERVATION AND ISSUANCE SHARES; CERTAIN CORPORATE ACTIONS.


     (a) The Issuer will at all times have authorized, and reserve and keep
available, free from preemptive rights, for the purpose of enabling it to
satisfy any obligation to issue Warrant Shares upon the exercise of the
Warrants, the number of shares of Common Stock deliverable upon exercise of all
outstanding Warrants.


     (b) The Issuer covenants that all Warrant Shares will, upon issuance in
accordance with the terms of this Warrant Agreement and the Issuer's Articles of
Incorporation, be fully paid and nonassessable and free from all taxes (except
as otherwise contemplated in Section 8 hereof) with respect to the issuance
thereof and from all liens, charges and security interests (other than any
created by or on behalf of any Warrant Holder).


     (c) The Issuer will not, by amendment of its Articles of Incorporation or
through any consolidation, merger, reorganization, transfer of assets,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant
Agreement or the Warrant Certificates. Without limiting the generality of the
foregoing, the Issuer (a) will not permit the par value or the determined or
stated value of any shares of the Issuer's Common Stock receivable upon the
exercise of the Warrants to exceed the amount payable therefor upon such
exercise, (b) will take all such action as may be necessary or 


                                       9
<PAGE>   10


appropriate in order that the Issuer may validly and legally issue fully paid
and nonassessable shares of the Issuer's Common Stock, upon the exercise of the
Warrants from time to time outstanding, including, without limitation, amending
its Articles of Incorporation to reduce or eliminate the par value of the Common
Stock and (c) will not take any action which results in an adjustment in the
number of Warrant Shares obtainable upon the exercise of any Warrants if the
total number of shares of the Issuer's Common Stock (or other securities)
issuable after such action upon the exercise of all of the then-outstanding
Warrants would exceed the total number of shares of the Issuer's Common Stock
(or other securities) then authorized by the Issuer's Articles of Incorporation
and available for purpose of issuance upon such exercise.


     (d) The Issuer agrees that it will not enter into an agreement providing
for a Non-Surviving Combination or effect any such Non-Surviving Combination
unless the party to such transaction that is the surviving entity thereof or the
purchaser or purchasers of substantially all of the assets of the Issuer (the
"Survivor") (i) shall be obligated to distribute or pay to each Warrant Holder,
upon payment of the Exercise Price prior to the Expiration Date, the number of
shares of stock or other securities or other property (including any cash) of
the Survivor that would have been distributable or payable on account of the
Warrant Shares if such Warrant Holder's Warrants had been exercised immediately
prior to such Non-Surviving Combination (or, if applicable, the record date
therefor), as such number of shares or other securities or other property may
thereafter be adjusted pursuant to Section 12 of this Warrant Agreement and (ii)
shall assume by written instrument all of the obligations of the Issuer under
this Warrant Agreement.


     (e) The Issuer will take no action with respect to its capital stock
(including without limitation any purchase of its shares or any combination of
shares or reverse stock split and elimination of fractional shares) which would
cause the sum of the number of Warrant Shares theretofore issued, if any, plus
the number of Warrant Shares then issuable in respect of Warrants then
outstanding to exceed 4.99% of the aggregate issued and outstanding shares of
the Issuer after giving effect to such action, unless in any such case the
holders of a majority of the outstanding Warrants and Warrant Shares shall have
given their prior written consent to such action.


     Section 11. OBTAINING OF GOVERNMENTAL APPROVALS AND STOCK EXCHANGE
Listings. Subject, in the case of any registration under the Securities Act, to
the limitations set forth in Section 15, the Issuer will, at its own expense,
from time to time take all action which may be necessary to obtain and keep
effective any and all permits, consents and approvals of governmental agencies
and authorities which are or become requisite in connection with the issuance,
sale, transfer and delivery of the Warrant Certificates and the exercise of the
Warrants and the issuance, sale, transfer and delivery of the Warrant Shares and
all action which may be necessary so that such Warrant Shares, immediately upon
their issuance upon the exercise of Warrants will be listed on each securities
exchange, if any, on which the Common Stock is then listed.


     Section 12. ADJUSTMENT OF NUMBER OF WARRANT SHARES PURCHASABLE.


                                       10
<PAGE>   11


     (a) The number of shares of Common Stock purchasable upon the exercise of
each Warrant is subject to adjustment from time to time upon the occurrence of
any of the events enumerated in this Section 12 at any time or from time to time
after the date hereof and prior to the Expiration Date.


     (b) If the Issuer shall (i) declare a dividend on the Common Stock in
shares of its capital stock (whether shares of Common Stock or of capital stock
of any other class), (ii) split or subdivide the outstanding Common Stock or
(iii) combine the outstanding Common Stock into a smaller number of shares, each
Warrant outstanding at the time of the record date for such dividend or of the
effective date of such split, subdivision or combination shall thereafter
entitle the holder of such Warrant to receive the aggregate number and kind of
shares which, if such Warrant had been exercised immediately prior to such time,
such holder would have owned or have become entitled to receive by virtue of
such dividend, subdivision or combination. Such adjustment shall be made
successively whenever any event listed above shall occur and, if a dividend
which is declared is not paid, each Warrant outstanding shall again entitle the
holder thereof to receive the number of shares of Common Stock as would have
been the case had such dividend not been declared. If at any time, as a result
of an adjustment made pursuant to this subsection 12(b), the holder of any
Warrant thereafter exercised shall become entitled to receive any shares of
capital stock of the Issuer other than shares of Common Stock, thereafter the
number of such other shares so receivable upon exercise of any Warrant shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the Warrant Shares
contained in this Section 12, and the provisions of this Warrant Agreement with
respect to the Warrant Shares shall apply on like terms to such other shares.


     (c) In case the Issuer shall make a distribution to all holders of Common
Stock (including any such distribution made in connection with a consolidation
or merger in which the issuer is the continuing corporation) of evidences of its
indebtedness, cash or other assets, other than ordinary cash dividends payable
to all holders of Common Stock, each Warrant outstanding on the date of such
distribution shall thereafter entitle the holder of such Warrant to receive a
number of shares of Common Stock equal to the product of (i) the number of
shares of Common Stock to which the holder of such Warrant was entitled
immediately prior to such date of distribution and (ii) a fraction of which the
numerator shall be the then Current Market Price Per Share of Common Stock on
such date and of which the denominator shall be the then Current Market Price
Per Share of Common Stock on such date less the fair market value, as reasonably
determined by the Board of Directors of the Issuer and reasonably acceptable to
the holders of a majority of the Warrants of the portion of the assets or
evidences of indebtedness, or the portion of the cash, so to be distributed
applicable to one share of then-outstanding Common Stock. Such adjustment shall
be made successively whenever a date for such distribution is fixed (which date
of distribution shall be the record date for such distribution if a record date
therefor is fixed) and, if such distribution is not so made, each Warrant
outstanding shall again entitle the holder thereof to receive the number of
shares of Common Stock as would have been the case had such date of distribution
not been fixed.


                                       11

<PAGE>   12


     (d) In the event that the Issuer pays a cash dividend to the holders of its
Common Stock, it shall also pay a cash dividend to all holders of Warrants which
dividend shall be calculated as if the Warrants had been exercised.


     (e) In the event of any capital reorganization of the Issuer, or of any
reclassification of the Common Stock (other than a subdivision or combination of
outstanding shares of Common Stock), or in case of the consolidation of the
Issuer with or the merger of the Issuer with or into any other corporation or of
the sale of the properties and assets of the Issuer as, or substantially as, an
entirety to any other corporation, each Warrant shall after such capital
reorganization, reclassification of Common Stock, consolidation, merger or sale
be exercisable upon the terms and conditions specified in this Warrant
Agreement, for the number of shares of stock or other securities or assets to
which a holder of the number of Warrant Shares purchasable (at the time of such
capital reorganization, reclassification of Common Stock, consolidation, merger
or sale) upon exercise of such Warrant would have been entitled upon such
capital reorganization, reclassification of Common Stock, consolidation, merger
or sale; and in any such case, if necessary, the provisions set forth in this
Section 12 with respect to the rights thereafter of the holders of the Warrants
shall be appropriately adjusted so as to be applicable, as nearly as may
reasonably be, to any shares of stock or other securities or assets thereafter
deliverable on the exercise of the Warrants.


     (f) If any event occurs, as to which, in the good faith opinion of the
Board of Directors of the Issuer, the other provisions of this Section 12 are
not strictly applicable or (if strictly applicable) would not fairly protect the
purchase rights of the Warrants in accordance with the essential intent and
principles of such provisions, then the Board of Directors shall make an
adjustment in the application of such provisions, in accordance with such
essential intent and principles, so as to protect such purchase rights as
aforesaid, but in no event shall any such adjustment have the effect of
decreasing the number of shares of Common Stock purchasable upon the exercise of
each Warrant from that which would otherwise be determined pursuant to this
Section 12.


     (g) No adjustment in the number of Warrant Shares purchasable shall be
required unless such adjustment would require an increase or decrease in the
aggregate number of Warrant Shares purchasable of at least 1%, provided that any
adjustments which by reason of this subsection 12(g) are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Section 12 shall be made to the nearest cent or to
the nearest hundredth of a share, as the case may be.


     (h) Irrespective of any adjustments in the number or kind of shares
purchasable upon the exercise of the Warrant, Warrant Certificates theretofore
or thereafter issued may continue to express the same number and kind of shares
as are stated on the Warrant Certificates initially issuable pursuant to this
Warrant Agreement.


     (i) If any question shall at any time arise with respect to the number of
Warrant Shares purchasable following any adjustment pursuant to this Section 12,
such question shall be 


                                       12
<PAGE>   13


determined by agreement between the holders of a majority of the Warrants and
the Issuer or, in the absence of such an agreement, by an independent investment
banking firm or an independent appraiser engaged by the Issuer (in either case
the cost of which engagement will be borne by the Issuer) and reasonably
acceptable to the Issuer and the holders of a majority of Warrants and such
determination shall be binding upon the Issuer and the holders of the Warrants.


     (j) Anything in this Section 12 to the contrary notwithstanding:


          (1) the Issuer shall be entitled to make such increases in the number
     of Warrant Shares purchasable upon the exercise of each Warrant, in
     addition to those adjustments required by this Section 12, as it in its
     sole discretion shall determine to be advisable in order that any
     consolidation or subdivision of the Common Stock, or any issuance wholly
     for cash or any shares of Common Stock at less than the Current Market
     Price Per share, or any issuance wholly for cash or shares of Common Stock
     or securities which by their terms are convertible into or exchangeable for
     shares of Common Stock or any stock dividend, or any issuance of rights,
     options or warrants referred to hereinabove in this Section 12, hereinafter
     made by the Issuer to the holders of its Common Stock shall not be taxable
     to them; and


          (2) no adjustment in the number of Warrant Shares purchasable shall be
     required in the event the Issuer pays a cash dividend to holders of Common
     Stock; provided that the Issuer also pays a cash dividend to all holders of
     Warrants which dividend shall be calculated as if the Warrants had been
     exercised.


     Section 13. NOTICES TO WARRANT HOLDERS; NOTICES OF ISSUANCES AND DIVIDENDS.


     (a) Upon any adjustment of the number of Warrant Shares purchasable upon
exercise of a Warrant pursuant to Section 12, the Issuer shall promptly but in
any event within 20 days thereafter, cause to be given to each of the registered
holders of the Warrants at its address appearing on the Warrant Register by
registered mail, postage prepaid, return receipt requested a certificate signed
by its chairman, president or chief financial officer setting forth the number
of Warrant Shares purchasable upon exercise of a Warrant as so adjusted and
describing in reasonable detail the facts accounting for such adjustment and the
method of calculation used. Where appropriate, such certificate may be given in
advance and included as a part of the notice required to be mailed under the
other provisions of this Section 13.


     (b) The Issuer shall deliver to each of the registered holders of the
Warrants at its address appearing on the Warrant Register, copies of all
information provided to holders of Common Stock concurrently with the delivery
thereof to such holders of Common Stock.


     Section 14. RESTRICTIONS ON TRANSFER.


     (a) Each of Lender and its Affiliates who are issued Warrants pursuant to
this Agreement (i) represents that it is acquiring the Warrants for its own
account for investment and not with a view to any distribution or public
offering within the meaning of the Securities Act, 


                                       13
<PAGE>   14


except in any case pursuant to the registration of such Warrants or Warrant
Shares under the Securities Act or pursuant to a valid exemption from such
registration requirement, (ii) acknowledges that the Warrants and the Warrant
Shares issuable upon exercise thereof have not been registered under the
Securities Act and (iii) agrees that it will not sell or otherwise transfer any
of its Warrants or Warrant Shares except upon the terms and conditions specified
herein and that it will cause any transferee thereof to agree to take and hold
the same subject to the terms and conditions specified herein, provided that the
Warrant Holders may sell the Warrants or the Warrant Shares purchased upon
exercise of the Warrants in one or more private transactions not requiring
registration under the Securities Act.


     (b) Except as provided in subsection 14(d) hereof each Warrant Certificate
and each certificate for the Warrant Shares issued to Lender or an Affiliate
thereof or to a subsequent transferee thereof pursuant to subsection 14(c) shall
include a legend in substantially the following form (with such changes therein
as may be appropriate to reflect whether such legend refers to Warrants or
Warrant Shares), provided that such legend shall not be required if such
transfer is being made in connection with a sale which is exempt from
registration pursuant to Rule 144 under the Securities Act or if the opinion of
counsel referred to in subsection 14(c) is to the further effect that neither
such legend nor the restrictions on transfer in this Section 14 are required in
order to ensure compliance with the Securities Act:

         THE WARRANTS AND SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY
         APPLICABLE STATE SECURITIES LAW AND MAY NOT BE SOLD OR TRANSFERRED IN
         THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH
         ACT OR LAW. SUCH WARRANTS AND SHARES MAY BE TRANSFERRED ONLY IN
         COMPLIANCE WITH THE CONDITIONS SPECIFIED IN AND ARE SUBJECT TO OTHER
         PROVISIONS OF THE WARRANT AGREEMENT, DATED AS OF FEBRUARY 20, 1997,
         BETWEEN THE ISSUER AND CREDITANSTALT CORPORATE FINANCE, INC., A
         COMPLETE AND CORRECT COPY OF WHICH IS AVAILABLE FOR INSPECTION AT THE
         PRINCIPAL OFFICE OF THE ISSUER AND WILL BE FURNISHED TO THE HOLDER
         HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE.

     (c) Prior to or promptly after any assignment, transfer or sale of any
Warrant or any Warrant Shares (other than a transfer among Lender and/or its
Affiliates), the holder thereof shall give written notice to the Issuer of such
holder's intention to effect such assignment, transfer or sale, which notice
shall set forth the date of such proposed assignment, transfer or sale and the
identity of the proposed transferee. Each holder wishing to effect such a
transfer of any Warrant or Warrant Shares shall also furnish to the Issuer an
agreement by the transferee thereof that it is taking and holding the same
subject to the terms and conditions specified herein and, unless the transferee
is an Affiliate of such holder, a written opinion of such holder's counsel, in
form reasonably satisfactory to the Issuer, to the effect that the proposed
transfer may be effected without registration under the Securities Act.


                                       14
<PAGE>   15



     (d) The restrictions set forth in this Section 14 shall terminate and cease
to be effective with respect to any Warrants or Warrant Shares which are
registered under the Securities Act or upon receipt by the Issuer of an opinion
of counsel, in form reasonably satisfactory to the Issuer, to the effect that
compliance with such restrictions is not necessary in order to comply with the
Securities Act with respect to the transfer of the Warrants and the Warrant
Shares; provided, however, that after three (3) years from the date of issuance
of any Warrants, such restrictions will automatically terminate (without the
necessity of any opinion of counsel) as to such Warrants and as to any Warrant
Shares issued in respect of such Warrants upon exercise of the Conversion Right
set forth in subsection 6(b) above. Whenever such restrictions shall so
terminate the holder of such Warrants and/or Warrant Shares shall be entitled to
receive from the Issuer, without expense (other than transfer taxes, if any),
Warrant Certificates or certificates for such Warrant Shares not bearing the
legend set forth in subsection 14(b) at which time the Issuer will rescind any
transfer restrictions relating thereto.


     (e) With a view to making available to Lender and its Affiliates and
subsequent holders of the Warrant Shares the benefits of certain rules and
regulations of the Securities and Exchange Commission (including, without
limitation, Rules 144 and 144A under the Securities Act) which may permit the
sale of Warrants and Warrant Shares to the public or certain other institutions
without registration, the Issuer agrees to take any and all such actions as may
be required of it to make available to Lender and its Affiliates and such
subsequent holders such benefits, including without limitation, to:


          (i) make and keep public information available, as those terms are
     understood and defined in Rule 144 under the Securities Act or any
     successor provision thereto from and after the date the Issuer first
     becomes subject to the provisions of Section 13 or 15(d) of the Exchange
     Act;


          (ii) file with the Commission in a timely manner all reports and other
     documents required of the Issuer under the Securities Act and the Exchange
     Act from and after the date the Issuer first becomes subject to the
     provisions of Section 13 or 15(d) of the Exchange Act; and


          (iii) so long as Lender or an Affiliate thereof owns any Warrants or
     Warrant Shares, furnish to Lender forthwith upon request a written
     statement by the Issuer as to its compliance with the reporting
     requirements of Rule 144 or any successor provision thereto, and of the
     Securities Act and the Exchange Act, a copy of the most recent annual or
     quarterly report of the Issuer filed with the Commission, in each case from
     and after the date the Issuer first becomes subject to the provisions of
     Section 13 or 15(d) of the Exchange Act, and such other reports and
     documents of the Issuer and other information in the possession of or
     reasonably obtainable by the Issuer as Lender and its Affiliates and
     subsequent holders of the Warrants may reasonably request in availing
     itself of any rule or regulation of the Commission allowing Lender and its
     Affiliates and subsequent holders of the Warrants to sell any such
     securities without registration.

<PAGE>   16



     Section 15. REGISTRATION.


     (a) If, at any time after the date hereof, the Issuer proposes to register
any of its securities under the Securities Act (except pursuant to a
registration statement filed on Form S-8 or Form S-4 or such other form as shall
be prescribed under the Act for the same purposes), it will at each such time
give written notice to all holders of outstanding Warrants and Non-Public
Warrant Shares of its intention to do so and upon the written request of any
holder thereof given within 10 days after the Issuer's giving of such notice,
the Issuer will use its reasonable best efforts to effect the registration of
the Warrants and/or Non-Public Warrant Shares which it shall have been so
requested to register by including the same in such registration statement all
to the extent required to permit the sale or other disposition thereof in
accordance with the intended method of sale or other disposition given in each
such request. If the registration of which the Issuer gives notice pursuant to
this subsection 15(a) is for an underwritten public offering, only Warrants or
Non-Public Warrant Shares which are to be included in the underwriting may be
included in such registration, and the Issuer shall have the right to designate
the managing underwriter(s) in any such underwritten public offering; provided
that (i) the Issuer shall use its best efforts to cause the managing
underwriter(s) to include the Warrants or Non-Public Warrant Shares requested to
be included in the registration in the underwriting; and (ii) if the managing
underwriter(s) determine(s) and advises the Issuer that the inclusion of some of
the Non-Public Warrant Shares requested to be included in the registration
concurrently with the securities being registered by the Issuer would interfere
with the successful marketing of such securities, then the number of Non-Public
Warrant Shares otherwise to be included in the registration statement by the
holders of the Non-Public Warrant Shares shall be reduced to the required level,
as follows: (A) first, in the event that the shares of capital stock being
registered in such proposed registration include shares of Common Stock to be
sold by the Company for its own account or shares of a securityholder (other
than such holders) who is selling such shares pursuant to "demand" registration
rights granted by the Company to such securityholder, by excluding the
Non-Public Warrant Shares proposed to be sold by the holders thereof, (B)
second, in the event that the shares of capital stock being registered in such
proposed registration include shares ("Priority Shares") of capital stock to be
sold in connection with a securityholder's exercise of the registration rights
granted by the Issuer to D. Blech & Company, Incorporated ("Blech") and to Alan
R. Ackerman ("Ackerman"), or their successors, pursuant to separate agreements
dated September 1, 1994 between the Issuer and each of Blech and Ackerman
(copies of which have been furnished to the Holders), by excluding the
Non-Public Warrant Shares proposed to be sold by such holders, (C) third, in the
event that the shares of capital stock being registered in such proposed
registration include shares of capital stock to be sold in connection with the
exercise by a securityholder (other than such holders) of "piggyback"
registration rights granted by the Company, by excluding, on a pro rata basis,
the shares of capital stock to be sold by such securityholder(s) and the
Non-Public Warrant Shares proposed to be sold by the holders thereof, and (D)
fourth, by reducing the participation of such Holders in such offering pro rata
among the Holders requesting such registration, based upon the number of
Non-Public Warrant Shares then owned by such Holders. Any registration statement
filed pursuant to this subsection 15(a) may be withdrawn at any time at the
discretion of the Issuer.


                                       16
<PAGE>   17



     (b) If a registration under subsection 15(a) shall be in connection with an
underwritten public offering, each holder of Warrants or Non-Public Warrant
Shares shall be deemed to have agreed by acquisition of such Warrants or
Non-Public Warrant Shares not to effect any sale or distribution, including any
sale pursuant to Rule 144 or Rule 144A, of any Warrants or Non-Public Warrant
Shares, and to use such holder's reasonable best efforts not to effect any such
sale or distribution of any other equity security of the Issuer or of any
security convertible into or exchangeable or exercisable for any equity security
of the Issuer (other than as part of such underwritten public offering) within
seven days before or 180 days after the effective date of such registration
statement (and the Issuer hereby also so agrees and agrees to cause each holder
of any equity security, or of any security convertible into or exchangeable or
exercisable for any equity security, of the Issuer purchased from the Issuer at
any time other than in a public offering, so to agree).


     (c) As a condition to the inclusion of a holder's Warrants or Non-Public
Warrant Shares in any registration statements, each such holder of Warrants or
Non-Public Warrant Shares requesting registration thereof will furnish to the
Issuer such information with respect to such holder as is required to be
disclosed in the registration statement (and the prospectus included therein) by
the applicable rules, regulations and guidelines of the Commission. Failure of a
holder to furnish such information or agreement shall not affect the obligation
of the Issuer under this Section 15 to the remaining holders who furnish such
information.


     (d) If and whenever the Issuer is required under this Section 15 to use its
reasonable best efforts to effect the registration of Warrants or Non-Public
Warrant Shares under the Securities Act, the Issuer shall:


          (i) as expeditiously as possible and subject to the limitations set
     forth in subsection 15(a), prepare and file with the Commission a
     registration statement on the appropriate form with respect to such
     Warrants or Non-Public Warrant Shares and use its best efforts to cause
     such registration statement to become effective as soon as practicable
     after such filing;


          (ii) as expeditiously as possible, prepare and file with the
     Commission such amendments and supplements (including post-effective
     amendments and supplements) to the registration statement covering such
     Warrants or Non-Public Warrant Shares and the prospectus used in connection
     therewith as may be necessary to keep such registration statement effective
     and usable for resale for a period necessary to complete the distribution
     of such securities, but in no event in excess of 90 days plus any period
     during which the holders of Warrants or Warrant Shares are obligated to
     refrain from selling because the Issuer is required to amend or supplement
     the prospectus under subsection 15(d)(iv), and to comply with the
     provisions of the Securities Act with respect to the disposition of all
     Warrants or Non-Public Warrant Shares covered by such registration
     statement during such period in accordance with the intended method of
     disposition of the sellers set forth therein;


                                       17
<PAGE>   18



          (iii) as expeditiously as possible, furnish to each seller of such
     Warrants or Non-Public Warrant Shares registered, or to be registered under
     the Securities Act, and to each underwriter, if any, of such Warrants or
     Non-Public Warrant Shares such number of copies of a prospectus and
     preliminary prospectus in conformity with the requirements of the
     Securities Act, and such other documents as such seller or underwriter may
     reasonably request in order to facilitate the public sale or other
     disposition of such Warrants or Non-Public Warrant Shares;


          (iv) as expeditiously as possible, notify each seller of such Warrants
     or Non-Public Warrant Shares if, at any time when a prospectus relating to
     such Warrants or Non-Public Warrant Shares, is required to be delivered
     under the Securities Act, any event shall have occurred as a result of
     which the prospectus then in use with respect to such Warrants or
     Non-Public Warrant Shares would include an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or for any other
     reason it shall be necessary to amend or supplement such prospectus in
     order to comply with the Securities Act and prepare and furnish to all
     sellers as promptly as possible, and in any event within ninety (90) days
     of such notice, a reasonable number of copies of a supplement to or an
     amendment of such prospectus which will correct such statement or omission
     or effect such compliance;


          (v) as expeditiously as possible, use its reasonable best effort to
     register or qualify such Warrants or Non-Public Warrant Shares under such
     other securities or blue sky laws of such jurisdictions as such seller
     shall reasonably request and do any and all other acts and things which may
     be reasonably necessary to enable such seller to consummate the public sale
     or other disposition in each such jurisdiction of the Warrants or
     Non-Public Warrant Shares owned by such seller and included in such
     registration statement, provided that the Issuer shall not be required to
     consent to the general service of process or to qualify to do business in
     any jurisdiction where it is not then qualified;


          (vi) use its reasonable best efforts to keep the holders of such
     Warrants or Non-Public Warrant Shares informed of the Issuer's best
     estimate of the earliest date on which such registration statement or any
     post-effective amendment or supplement thereto will become effective and
     will promptly notify such holders and the managing underwriters, if any,
     participating in the distribution pursuant to such registration statement
     of the following: (A) when such registration statement or any
     post-effective amendment or supplement thereto becomes effective or is
     approved; (B) of the issuance by any competent authority of any stop order
     suspending the effectiveness or qualification of such registration
     statement or the prospectus then in use or the initiation or threat of any
     proceeding for that purpose; and (C) of the suspension of the qualification
     of any Warrants or Non-Public Warrant Shares included in such registration
     statement for sale in any jurisdiction;

          (vii) make available to its security holders, as soon as practicable,
     an earnings statement covering a period of at least twelve months which
     satisfies the provisions of Section 11(a) of the Securities Act and Rule
     158 thereunder;


          (viii) cooperate with the sellers of such Warrants or Non-Public
     Warrant Shares and the underwriters, if any, of such Warrants or Non-Public
     Warrant Shares in the event that Warrants or Non-Public Warrant Shares are
     to be sold in an underwritten offering, enter into an underwriting
     agreement containing customary representations and warranties, covenants,
     conditions and indemnification provisions, including without limitation the
     furnishing to the underwriters of a customary opinion of independent
     counsel to the Issuer and a customary "comfort" letter from the Issuer's
     independent public accountants;


          (ix) as to all registrations, pay all costs and expenses incident to
     the performance and compliance by the Issuer of this Section 15 other than
     underwriting discounts and commissions, including without limitation (A)
     all registration and filing fees; (B) all printing expenses; (C) all fees
     and disbursements of counsel and independent public accountants for the
     Issuer; (D) all blue sky fees and expenses (including fees and expenses of
     counsel in connection with blue sky surveys); (E) all transfer taxes; (F)
     the entire expense of any special audits required by the rules and
     regulations of the Commission; (G) the cost of distributing prospectuses in
     preliminary and final form as well as any supplements thereto and (H) the
     fees and expenses of one counsel for the holders of the Warrants or
     Non-Public Warrant Shares being registered; and


     (e) (i)The Issuer will indemnify and hold harmless each seller of Warrants
or Non-Public Warrant Shares, each director, officer, employee and agent of each
seller, and each other person, if any, who controls such seller within the
meaning of the Securities Act or the Exchange Act from and against any and all
losses, claims, damages, liabilities and legal and other expenses (including
costs of investigation) caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement under which
such Warrants or Non-Public Warrant Shares were registered under the Securities
Act, any prospectus or preliminary prospectus contained therein or any amendment
or supplement thereto, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to such seller and furnished to the Issuer in writing by such seller expressly
for use therein, and provided that the Issuer will not be liable to any Person
who participates as an underwriter in the offering or sale of Warrants or
Non-Public Warrant Shares or any other Person, if any, who controls such
underwriter within the meaning of the Securities Act under the indemnity
agreement in this subsection 15(e) with respect to any preliminary prospectus or
the final prospectus or the final prospectus as amended or supplemented, as the
case may be, to the extent that any such loss, claim, damage or liability of
such underwriter or controlling Person results from 


                                       19
<PAGE>   20


the sale by such underwriter of Warrants or Non-Public Warrant Shares to a
Person to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the final prospectus or of the final
prospectus as then amended or supplemented, whichever is most recent, if the
Issuer has previously furnished copies thereof to such underwriter, or from a
sale to a Person in a state where the offering has not been registered or
qualified, if the Issuer has notified the seller and any underwriter involved in
such sale of the states where the offering has been registered or qualified.


          (ii) It shall be a condition to the obligation of the Issuer to effect
     a registration of Warrants or Non-Public Warrant Shares under the
     Securities Act pursuant hereto that (X) each seller, severally and not
     jointly, indemnify and hold harmless the Issuer and each person, if any,
     who controls the Issuer within the meaning of the Securities Act or the
     Exchange Act to the same extent as the indemnity from the Issuer in the
     foregoing paragraph, but only with reference to any breach by such seller
     of any agreement between such seller, and the Issuer with respect to the
     offering and with reference to information relating to such seller
     furnished to the Issuer in writing by such seller expressly for use in the
     registration statement, any prospectus or preliminary prospectus contained
     therein or any amendment or supplement thereto and (Y) each seller, in the
     event that Warrants or Non-Public Warrant Shares are to be sold in an
     underwritten offering, enters into an underwriting agreement containing
     customary representations and warranties, covenants, conditions and
     indemnification provisions.


          (iii) In case any claim shall be made or any proceeding (including any
     governmental investigation) shall be instituted involving any indemnified
     party in respect of which indemnity may be sought pursuant to this
     subsection 15(e), such indemnified party shall promptly notify the
     indemnifying party in writing of the same, provided that failure to notify
     the indemnifying party shall not relieve it from any liability it may have
     to an indemnified party otherwise than under this subsection 15(e). The
     indemnifying party, upon request of the indemnified party, shall retain
     counsel reasonably satisfactory to the indemnified party to represent the
     indemnified party in such proceeding and shall pay the fees and
     disbursements of such counsel. In any such proceeding, any indemnified
     party shall have the right to retain its own counsel, but the fees and
     disbursements of such counsel shall be at the expense of such indemnified
     party unless (A) the indemnifying party shall have failed to retain counsel
     for the indemnified party as aforesaid, (B) the indemnifying party and such
     indemnified party shall have mutually agreed to the retention of such
     counsel or (C) representation of such indemnified party by the counsel
     retained by the indemnifying party would, in the reasonable opinion of the
     indemnified party, be inappropriate due to actual or potential differing
     interests between such indemnified party and any other party represented by
     such counsel in such proceeding, provided that the Issuer shall not be
     liable for the fees and disbursements of more than one additional counsel
     for all indemnified parties. The indemnifying party shall not be liable for
     any settlement of any proceeding effected without its written consent but
     if settled with such consent or if there be a final judgment for the
     plaintiff, the indemnifying party agrees to 


                                       20
<PAGE>   21


     indemnify the indemnified party from and against any loss or liability by
     reason of such settlement or judgment.


     (f) In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in subsection 15(e) is
due in accordance with its terms but is for any reason held by a court to be
unavailable on grounds of policy or otherwise, the Issuer or the applicable
sellers, as the case may be, shall contribute to the aggregate losses, claims,
damages and liabilities incurred (including legal or other expenses reasonably
incurred in connection with the investigating or defending of same) by the other
and for which such indemnification was sought. In determining the amount of
contribution to which the respective parties are entitled, there shall be
considered the relative benefits received by each party from the offering of the
securities included in the registration statement (taking into account the
portion of the proceeds of the offering realized by each), the parties' relative
knowledge and access to information concerning the matter with respect to which
the claim was asserted, the opportunity to correct and prevent any statement or
omission, and any other equitable considerations appropriate in the
circumstances; provided, however, that (i) in no case shall any seller of
Warrants or Non-Public Warrant Shares be required to contribute any amount in
excess of the total public offering price of the Warrants or Non-Public Warrant
Shares sold by him and (ii) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this subsection 15(f), each person who
controls any seller of Warrants or Non-Public Warrant Shares or the Issuer shall
have the same rights to contribution as such seller or the Issuer. Any party
entitled to contribution shall, promptly after receipt of notice of commencement
of any action, suit or proceeding against such party in respect of which a claim
for contribution may be made against the Issuer or the seller of Warrants or
Non-Public Warrant Shares under this subsection 15(f), notify the Issuer or such
seller, as the case may be, but the omission to so notify the Issuer or such
seller, as the case may be, shall not relieve it from any other obligation it
may have hereunder or otherwise.


     (g) After the date hereof, the Issuer shall not grant to any holder of
securities of the Issuer any registration rights which have a priority greater
than or equal to those granted to holders of Warrants or Non-Public Warrant
Shares pursuant to this Section 15 without the prior written consent of the
holders of at least a majority of the aggregate outstanding Warrants and
Non-Public Warrant Shares, voting as a single group.


     Section 16. AMENDMENTS AND WAIVERS. Any provision of this Warrant Agreement
may be amended, supplemented, waived, discharged or terminated by a written
instrument signed by the Issuer and the holders of not less than a majority of
the outstanding Warrants (or in the case of Sections 14 and 15, the holders of a
majority of the aggregate outstanding Warrants and Non-Public Warrant Shares,
voting as a single group), provided that (i) this Agreement may not be amended,
supplemented or waived so as to increase the Exercise Price, reduce the number
of Warrant Shares issuable upon exercise of any Warrants, alter the period
during which any Warrants may be exercised, (except to provide for a later
Expiration Date) or in each case without the consent of the holders of all
outstanding Warrants and (ii) this Section 16 may not be amended 


                                       21
<PAGE>   22


or supplemented without the consent of the holders of all outstanding Warrants
and Non-Public Warrant Shares, voting as a single group, and no waiver of the
requirements of this Section 16 shall be binding upon any such holder without
its consent.


     Section 17. SPECIFIC PERFORMANCE. The parties agree that irreparable damage
will result in the event that the obligations of the Issuer under this Warrant
Agreement are not specifically enforced, and that any damages available at law
for a breach of any such obligations would be inadequate. Therefore, the holders
of the Warrants and/or Non-Public Warrant Shares shall have the right to
specific performance by the Issuer of the provisions of this Warrant Agreement,
and appropriate injunctive relief may be applied for and granted in connection
therewith. The Issuer hereby irrevocably waives, to the extent that it may do so
under applicable law, any defense based on the adequacy of a remedy at law which
may be asserted as a bar to the remedy of specific performance in any action
brought against the Issuer for specific performance of this Warrant Agreement by
the holders of the Warrants and/or Non-Public Warrant Shares. Such remedies and
all other remedies provided for in this Warrant Agreement shall, however, be
cumulative and not exclusive and shall be in addition to any other remedies
which may be available under this Warrant Agreement.


     Section 18. NOTICES.


     (a) Any notice or demand to be given or made by the Warrant Holders or the
holders of Warrant Shares to or on the Issuer pursuant to this Warrant Agreement
shall be sufficiently given or made if sent by registered mail, return receipt
requested, postage prepaid, addressed to the Issuer at the Warrant Office.


     (b) Any notice to be given by the Issuer to the Warrant Holders or the
holders of Warrant Shares shall be sufficiently given or made if sent by
registered mail, return receipt requested, postage prepaid, addressed to such
holder as such holder's name and address shall appear on the Warrant Register or
the Common Stock registry of the Issuer, as the case may be.


         Section 19. BINDING EFFECT. This Warrant Agreement shall be binding
upon and inure to the sole and exclusive benefit of the Issuer, its successors
and assigns, Lender, Affiliates of Lender and the registered holders from time
to time of the Warrants and the Warrant Shares.


         Section 20. CONTINUED VALIDITY. A holder of Warrant Shares shall
continue to be entitled with respect to such Warrant Shares to all rights and
subject to all obligations to which it would have been entitled or subject as a
Warrant Holder under Sections 14 through 23 of this Warrant Agreement. The
Issuer will, at the time of each exercise of any Warrant, in whole or in part,
upon the request of the holder of the Warrant Shares issued upon such exercise
thereof, acknowledge in writing, in form reasonably satisfactory to such holder,
its continuing obligation to afford to such holder all such rights, provided,
however, that if such holder shall fail to make any such request, such failure
shall not affect the continuing obligation of the Issuer to afford to such
holder all such rights.

     Section 21. COUNTERPARTS. This Warrant Agreement may be executed in one or
more separate counterparts and all of said counterparts taken together shall be
deemed to constitute one and the same instrument.


     Section 22. NEW YORK LAW. THIS WARRANT AGREEMENT AND EACH WARRANT
CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK.


     Section 23. BENEFITS OF THIS WARRANT AGREEMENT. Nothing in this Warrant
Agreement shall be construed to give to any Person other than the Issuer and the
registered holders of the Warrants and the Warrant Shares any legal or equitable
right, remedy or claim under this Warrant Agreement.


     Section 24. VOTING AND CONSENTS TO BE ON A FULLY CONVERTED BASIS. Wherever
this Warrant Agreement calls for the written consent or vote of any combinations
of the holders of the Warrants, any of the Warrant Shares, voting as a single
group, the Warrants shall be counted as if they had been exercised for Common
Stock.


     Section 25. ENTIRE AGREEMENT. This Warrant Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof
and supersedes all prior negotiations, understandings and agreements between
such parties in respect of such subject matter.

                               WARRANT CERTIFICATE


     THE WARRANTS AND SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
SECURITIES LAW AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT OR LAW. SUCH WARRANTS AND
SHARES MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH THE CONDITIONS SPECIFIED IN
AND ARE SUBJECT TO OTHER PROVISIONS OF THE WARRANT AGREEMENT, DATED AS OF
FEBRUARY 20, 1997, BETWEEN THE ISSUER AND CREDITANSTALT CORPORATE FINANCE, INC.,
A COMPLETE AND CORRECT COPY OF WHICH IS AVAILABLE FOR INSPECTION AT THE
PRINCIPAL OFFICE OF THE ISSUER AND WILL BE FURNISHED TO THE HOLDER HEREOF UPON
WRITTEN REQUEST AND WITHOUT CHARGE.


     THE WARRANTS REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
EXCHANGE RIGHTS MORE FULLY SET FORTH IN THE WARRANT AGREEMENT.

                          EXERCISABLE ONLY ON OR BEFORE
                                December 31, 2003


                               Warrant Certificate

     This Warrant Certificate certifies that CREDITANSTALT CORPORATE FINANCE,
INC., or registered assigns, is the registered holder of 150,000 Warrants (the
"Warrants") to purchase Common Stock of SIGHT RESOURCE CORPORATION, a Delaware
corporation (the "Issuer"). Each Warrant entitles the holder, but only subject
to the conditions set forth herein and in the Warrant Agreement referred to
below, to purchase from the Issuer before 5:00 P.M., New York time, on December
31, 2003 (the "Expiration Date"), one (1) fully paid and nonassessable share of
the Common Stock of the Issuer (the "Warrant Shares") in the percentages and to
the extent set forth in the Warrant Agreement, at a price (the "Exercise Price")
of $4.625 per Warrant payable in lawful money of the United States of America,
upon surrender of this Warrant Certificate, execution of the annexed Form of
Election to Purchase and payment of the Exercise Price at the office of the
Issuer at 67 South Bedford Street, Burlington, Massachusetts 01803 or such other
address as the Issuer may specify in writing to the registered holder of the
Warrants evidenced hereby (the "Warrant Office"). In lieu of exercising Warrants
pursuant to the immediately preceding sentence, the Warrant holder shall have
the right to require the Issuer to convert the Warrants, in whole or in part and
at any time or times, into Warrant Shares, by surrendering to the Issuer the
Warrant Certificate evidencing the Warrants to be converted, accompanied by the
annexed Form of Notice of Conversion which has been duly completed and signed.
The Exercise Price and number of Warrant Shares purchasable upon exercise of the
Warrants are subject to adjustment prior to the Expiration Date as set forth in
the Warrant Agreement. In no event shall this Warrant be exercisable for shares
of Common Stock which, 

<PAGE>   26



when aggregated with all other Warrant Shares (as defined in the Warrant
Agreement) previously issued (other than Non-Attributable Stock (as defined in
the Warrant Agreement)) would, upon issuance, represent in excess of 24.99% of
the Equity of the Issuer (defined in the Warrant Agreement) unless such shares,
when issued, would constitute Non-Attributable Stock (as defined in the Warrant
Agreement).


     No Warrant may be exercised after 5:00 P.M., New York time, on the
Expiration Date and (except as otherwise provided in the Warrant Agreement) all
rights of the registered holders of the Warrants shall cease after 5:00 P.M.,
New York time, on the Expiration Date.


     The Issuer may deem and treat the registered holders of the Warrants
evidenced hereby as the absolute owners thereof (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof and of any distribution to the holders hereof and for all other
purposes, and the Issuer shall not be affected by any notice to the contrary.


     Warrant Certificates, when surrendered at the office of the Issuer at the
above-mentioned address by the registered holder hereof in person or by a legal
representative duly authorized in writing, may be exchanged, in the manner and
subject to the limitations provided in the Warrant Agreement, but without
payment of any service charge, for another Warrant Certificate or Warrant
Certificates of like tenor evidencing in the aggregate a like number of
Warrants.


     Upon due presentment for registration of transfer of this Warrant
Certificate at the office of the Issuer at the above-mentioned address, a new
Warrant Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued in exchange for this Warrant
Certificate to the transferee(s) and, if less than all the Warrants evidenced
hereby are to be transferred, to the registered holder hereof, subject to the
limitations provided in the Warrant Agreement, without charge except for any tax
or other governmental charge imposed in connection therewith.


     This Warrant Certificate is one of the Warrant Certificates referred to in
the Warrant Agreement, dated as of February 20, 1997, between the Issuer and
Creditanstalt Corporate Finance, Inc. Said Warrant Agreement is hereby
incorporated by reference in and made a part of this instrument and is hereby
referred to for a description of the rights, limitation of rights, obligations,
duties and immunities thereunder of the Issuer and the holders.


     IN WITNESS WHEREOF the Issuer has caused this Warrant Certificate to be
signed by its duly authorized officer.

          3.2. RIGHTS, TITLE AND INTEREST OF COLLATERAL ACCOUNT. All right,
     title and interest in and to the Collateral Account shall vest exclusively
     in the Lender. The Borrower shall have no rights with respect to the
     Collateral Account and the Lender shall have sole dominion and control over
     the Collateral Account and the monies deposited therein. Monies deposited
     in the Collateral Account shall constitute security for the Secured
     Obligations. The Borrower hereby pledges and assigns to the Lender and
     hereby grants to the Lender a security interest in, all right, title or
     interest (if any) which the Borrower now has or may hereafter have or
     purport or claim to have in or to the Collateral Account and all monies
     held therein, any investments made with such monies and any and all
     certificates or instruments from time to time representing or evidencing
     such investments (and all proceeds thereof).


          3.3. MAINTAINING THE COLLATERAL ACCOUNT. Until the Termination Date of
     this Agreement, all monies received by the Lender while a Default or an
     Event of Default has occurred and is continuing, all monies received
     pursuant to subsection 4.5(a) and Section 9 of the Credit Agreement, and
     any monies received as a result of investments made as contemplated by
     Section 4 hereof, shall be deposited in the Collateral Account.


     4. INVESTMENT OF MONIES. Pending the disbursement thereof pursuant to the
terms of this Agreement, all monies in the Collateral Account shall (to the
extent it is practical to do so) be invested by the Lender in Cash Equivalents
(as defined in the Credit Agreement). All such investments shall be evidenced
either (a) by negotiable certificates or instruments which are held by or for
the account of the Lender or (b) by book entries maintained in a State in which
the Lender may be granted by book entries a security interest in the securities
relating thereto. In the absence of its gross negligence or willful misconduct,
the Lender shall not have any ability out of or in connection with any
investment made in accordance with the provisions herein or for any loss or
decline in value of any investment or from any loss resulting directly or
indirectly from any investment made pursuant to and in accordance with the
provisions hereof.


     5. REPRESENTATIONS AND WARRANTIES. The Borrower hereby represents and
warrants that:

     to the Lender pursuant to this Agreement and the other Liens permitted to
     exist on the Collateral pursuant to the Credit Agreement, the Borrower owns
     each item of the Collateral free and clear of any and all Liens or claims
     of others. No financing statement or other public notice with respect to
     all or any part of the Collateral is on file or of record in any public
     office, except such as have been filed in favor of the Lender pursuant to
     this Agreement or as are permitted pursuant        to the Credit Agreement.


          5.2. PERFECTED FIRST PRIORITY LIENS. The security interests granted
     pursuant to this Agreement (a) constitute perfected security interests in
     the Collateral in favor of the Lender, as collateral security for the
     Secured Obligations and (b) are prior to all other Liens on the Collateral
     in existence on the date hereof except as set forth on SCHEDULE V to the
     Credit Agreement.

     Paper shall be immediately delivered to the Lender, duly indorsed in a
     manner satisfactory to the Lender, to be held as Collateral pursuant to
     this Agreement.


          6.2. Maintenance of Insurance.
               ------------------------


               (a) The Borrower will maintain, with financially sound and
          reputable companies, insurance policies insuring the Inventory and
          Equipment against loss by fire, explosion, theft and such other
          casualties as may be reasonably satisfactory to the Lender, such
          policies to be in such form and amounts and having such coverage as
          may be reasonably satisfactory to the Lender, with losses payable to
          the Borrower and the Lender as their respective interests may appear.


               (b) All such insurance shall (1) provide that no cancellation,
          material reduction in amount or material change in coverage thereof
          shall be effective until at least 30 days after receipt by the Lender
          of written notice thereof, (2) name the Lender as an insured party and
          (3) be reasonably satisfactory in all other respects to the Lender.


               (c) The Borrower shall deliver to the Lender a report of a
          reputable insurance broker with respect to such insurance in each
          calendar year and such supplemental reports with respect thereto as
          the Lender may from time to time reasonably request.


          6.3. MAINTENANCE OF PERFECTED SECURITY INTEREST; FURTHER
     DOCUMENTATION.


               (a) The Borrower shall maintain the security interest created by
          this Agreement as a perfected security interest having at least the
          priority described in subsection 5.2 and shall defend such security
          interest against the claims and demands of all Persons whomsoever.

                                       6
<PAGE>   7

               (b) At any time and from time to time, upon the written request
          of the Lender, and at the sole expense of the Borrower, the Borrower
          will promptly and duty execute and deliver such further instruments
          and documents and take such further actions as the Lender may
          reasonably request for the purpose of obtaining or preserving the full
          benefits of this Agreement and of the rights and powers herein
          granted, including, without limitation, the filing of any financing or
          continuation statements under the Uniform Commercial Code in effect in
          any jurisdiction with respect to the security interests created
          hereby.


          6.4. CHANGES IN LOCATIONS, NAME, ETC. The Borrower will not unless it
     shall have given the Lender at least 30 days prior written notice of such
     change (or, in the case of Inventory and Equipment, at least 10 days prior
     written notice, to the extent that the Borrower has taken such action as
     reasonably may be required of it to maintain the continuous perfection of
     the Lender's security interest in such Inventory or Equipment, as the case
     may be):


               (a) permit any of the Inventory (other than goods-in-transit and
          immaterial amounts of goods in temporary locations in the ordinary
          course of business) or Equipment to be kept at a location other than
          those listed on SCHEDULE 4; or

          specified in subsection 5.4;


               (c) change its name, identity or corporate structure to such an
          extent that any financing statement filed by the Lender in connection
          with this Agreement would become seriously misleading.


          6.5. FURTHER IDENTIFICATION OF COLLATERAL. The Borrower will furnish
     to the Lender from time to time statements and schedules further
     identifying and describing the Collateral and such other reports in
     connection with the Collateral as the Lender may reasonably request, all in
     reasonable detail.

     reasonable detail, at its address provided in subsection 11.2 of the Credit
     Agreement of (a) any Lien (other than security interests created hereby or
     Liens permitted under the Credit Agreement) on any of the Collateral and
     (b) the occurrence of any other event which could reasonably be expected to
     have a material adverse effect on the aggregate value of the Collateral or
     on the security interests created hereby.


     7. PROVISIONS RELATING TO RECEIVABLES.
        ---------------------------------

          7.1 BORROWER REMAINS LIABLE UNDER RECEIVABLES. Anything herein to the
     contrary notwithstanding, the Borrower shall remain liable under each of
     the Receivables to observe and perform all the conditions and obligations
     to be observed and

                                       7

                                       
<PAGE>   8

     performed by it thereunder, all in accordance with the terms of any
     agreement giving rise to each such Receivable. The Lender shall not have
     any obligation or liability under any Receivable (or any agreement giving
     rise thereto) by reason of or arising out of this Agreement or the receipt
     by the Lender of any payment relating to such Receivable pursuant hereto,
     nor shall the Lender be obligated in any manner to perform any of the
     obligations of the Borrower under or pursuant to any Receivable (or any
     agreement giving rise thereto), to make any payment, to make any inquiry as
     to the nature or the sufficiency of any payment received by it or as to the
     sufficiency of any performance by any party under any Receivable (or any
     agreement giving rise thereto), to present or file any claim, to take any
     action to enforce any performance or to collect the payment of any amounts
     which may have been assigned to it or to which it may be entitled at any
     time or times.


          7.2 ANALYSIS OF RECEIVABLES. The Lender shall have the right to make
     test verifications of the Receivables in any manner and through any medium
     that it reasonably considers advisable, and the Borrower shall furnish all
     such assistance and information as the Lender may reasonably require in
     connection with such test verifications. At any time and from time to time,
     upon the Lender's reasonable request and at the expense of the Borrower,
     the Borrower shall cause independent public accountants or others
     satisfactory to the Lender to furnish to the Lender reports showing
     reconciliations, aging and test verifications of, and trial balances for,
     the Receivables. The Lender, in its own name or in the name of others, may
     during such time as a Default or an Event of Default shall have occurred
     and be continuing, communicate with the obligors on the Receivables to
     verify with them to the Lender's satisfaction the existence, amount and
     terms of any Receivables.

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

               (a) The Lender hereby authorizes the Borrower to collect the
          Receivables subject to the Lender's direction and control, and the
          Lender may curtail or terminate said authority at any time when a
          Default or an Event of Default has occurred and is continuing and may
          then direct that payments on the Receivables be made directly to the
          Lender in accordance with the provisions of subsection 11.1. If
          required by the Lender at any time when a Default or an Event of
          Default has occurred and is continuing any payments of Receivables,
          when collected by the Borrower, (1) shall be forthwith (and, in any
          event, within two Business Days) deposited by the Borrower in the
          exact form received, duly indorsed by the Borrower to the Lender if
          required, in a Collateral Account maintained under the sole dominion
          and control of the Lender, subject to withdrawal by the Lender only as
          provided in subsection 10.3 and (2) until so turned over, shall be
          held by the Borrower in trust for the Lender, segregated from other
          funds of the Borrower.


               (b) Each such deposit of Proceeds of Receivables shall be
          accompanied by a report (in the form customarily prepared by the

                                       8
                                       
<PAGE>   9

          Borrower for its internal purposes) identifying in reasonable detail
          the nature and source of the payments included in the deposit.


               (c) At the Lender's request at any time when a Default or an
          Event of Default has occurred and is continuing the Borrower shall
          deliver to the Lender all original and other documents evidencing, and
          relating to, the agreements and transactions which gave rise to the
          Receivables, including, without limitation, all original orders,
          invoices and shipping receipts.


          7.4. Representations and Warranties.
               ------------------------------

               (a) No amount payable to the Borrower under or in connection with
          any Receivable is evidenced by any Instrument or Chattel Paper which
          has not been delivered to the Lender.

               (b) The Borrower will deliver to the Lender a copy of each

               (a) The Borrower (either itself or through licensees) will (i)
          employ the appropriate notice of copyright for each work subject to
          copyright protection to the extent necessary to protect any material
          registered Copyright relating to such work and (ii) not (and not

          determination or development in, any court or tribunal in the United
          States or any political subdivision thereof) regarding the Borrower's

          a document confirming the Lender's security interest in each
          registered Copyright with respect to which the Borrower acquires an
          interest during the two preceding calendar quarters, duly executed and
          in proper form for filing in the United States Copyright Office or
          other applicable United States Governmental Authority. Upon request of
          the Lender, the Borrower shall execute and deliver any and all
          additional agreements, instruments, documents, and papers as the
          Lender may reasonably request to confirm the Lender's security

          foregoing purposes, all lawful acts of such attorney being hereby
          ratified and confirmed; such power being coupled with an interest is

                                       12                                       
<PAGE>   13



               (e) The Borrower will take all necessary steps, as it shall deem
          appropriate under the circumstances, in accordance with its reasonable
          business judgment, to maintain and pursue each material application
          filed (and to obtain the relevant registration) and to maintain to the
          extent permitted by law each registration of each material Copyright
          owned by the Borrower including, without limitation, filing of

          appropriate under the circumstances to protect such Copyright,
          including, where appropriate in accordance with its reasonable
          business judgment, the bringing of suit or the settling of actual or
          potential suits for infringement, seeking injunctive relief and
          seeking to recover any and all damages for such infringement.


     10 Remedies.
        --------


          10.1. NOTICE TO OBLIGORS. Upon the request of the Lender at any time
     when a Default or an Event of Default has occurred and is continuing the
     Borrower shall notify obligors on the Receivables that the Receivables have
     been assigned to the Lender and that payments in respect thereof shall be
     made directly to the Lender.


          10.2. PROCEEDS TO BE TURNED OVER TO THE LENDER. In addition to the
     rights of the Lender specified in subsection 7.3 with respect to payments
     of Receivables, when a Default or an Event of Default has occurred and is
     continuing all Proceeds received by the Borrower consisting of cash, checks
     and other near-cash items shall be held by the Borrower in trust for the
     Lender, segregated from other funds of the Borrower, and shall, forthwith
     upon receipt by the Borrower, be turned over to the Lender in the exact
     form received by the Borrower (duly indorsed by the Borrower to the Lender,
     if required) and held by the Lender in the Collateral Account. All Proceeds
     while held by the Lender in the Collateral Account (or by the Borrower in
     trust for the Lender) shall continue to be held as collateral security for
     all the Secured Obligations and shall not constitute payment thereof until
     applied as provided in subsection 10.3.


          10.3. APPLICATION OF PROCEEDS. At such intervals as may be agreed upon
     by the Borrower and the Lender, or, if an Event of Default has occurred and
     is continuing at any time at the Lender's election, the Lender may apply
     all or any part of Proceeds held in any Collateral Account in payment of
     the Secured Obligations in such order as the Lender may elect, and any part
     of such funds which the Lender elects not so to apply and deems not
     required as collateral security for the Secured Obligations shall be paid
     over from time to time by the Lender to the Borrower or to whomsoever may
     be lawfully entitled to receive the same. Any balance of such Proceeds when
     no Default or Event of Default is continuing shall be paid over to the
     Borrower or to whomsoever may be lawfully entitled to receive the same. Any
     balance of such Proceeds remaining after the 

                                       13
                                       
<PAGE>   14


     Secured Obligations shall have been paid in full and the Commitments under
     (and as defined in) the Credit Agreement shall have expired or otherwise
     been terminated shall be paid over to the Borrower or to whomsoever may be
     lawfully entitled to receive the same.


          10.4. CODE REMEDIES. If an Event of Default has occurred and is
     continuing, the Lender may exercise, in addition to all other rights and
     remedies granted to it in this Agreement and in any other instrument or
     agreement securing, evidencing or relating to the Secured Obligations, all
     rights and remedies of a secured party under the Code. Without limiting the
     generality of the foregoing, the Lender, without demand of performance or
     other demand, presentment, protest, advertisement or notice of any kind
     (except any notice required by law referred to below) to or upon the
     Borrower or any other Person (all and each of which demands, defenses,
     advertisements and notices are hereby waived), may in such circumstances
     forthwith collect, receive, appropriate and realize upon the Collateral, or
     any part thereof, and/or may forthwith sell, lease, assign, give option or
     options to purchase, or otherwise dispose of and deliver the Collateral or
     any part thereof (or contract to do any of the foregoing), in one or more
     parcels at public or private sale or sales, at any exchange, broker's board
     or office of the Lender or elsewhere upon such terms and conditions as it
     may deem advisable and at such prices as it may deem best, for cash or on
     credit or for future delivery without assumption of any credit risk. The
     Lender shall have the right upon any such public sale or sales, and, to the
     extent permitted by law, upon any such private sale or sales, to purchase
     the whole or any part of the Collateral so sold, free of any right or
     equity of redemption in the Borrower, which right or equity is hereby
     waived or released. The Borrower further agrees, at the Lender's request,
     to assemble the Collateral and make it available to the Lender at places
     which the Lender shall reasonably select, whether at the Borrower's
     premises or elsewhere. To the extent permitted by applicable law, the
     Borrower waives all claims, damages and demands it may acquire against the
     Lender arising out of the exercise by them of any rights hereunder. If any
     notice of a proposed sale or other disposition of Collateral shall be
     required by law, such notice shall be deemed reasonable and proper if given
     at least 10 days before such sale or other disposition.


     11. LENDER APPOINTMENT AS ATTORNEY-IN-FACT; LENDER PERFORMANCE OF
BORROWER'S OBLIGATIONS.


          11.1. POWERS. The Borrower hereby irrevocably constitutes and appoints
     the Lender and any officer or agent thereof, with full power of
     substitution, as its true and lawful attorney-in-fact with full irrevocable
     power and authority in the place and stead of the Borrower and in the name
     of the Borrower or in its own name, for the purpose of carrying out the
     terms of this Agreement, to take any and all appropriate action and to
     execute any and all documents and instruments which may be necessary or
     desirable to accomplish the purposes of this Agreement, and, without
     limiting the generality of the foregoing, the Borrower hereby gives the
     Lender the power and right, on behalf of the Borrower, without notice to or
     assent by the Borrower, to do any or all of the following:


               (a) at any time when a Default or an Event of Default has
          occurred and is continuing in the name of the Borrower or its own
          name,

          or otherwise, take possession of and indorse and collect any checks,

          moneys due under any Receivable or with respect to any other
          Collateral and file any claim or take any other action or proceeding
          in any court of law or equity or otherwise deemed appropriate by the

          payable;


               (b) in the case of any Copyright, Patent or Trademark, execute
          and deliver any and all agreements, instruments, documents and papers

          intangibles of the Borrower relating thereto or represented thereby;


               (c) pay or discharge taxes and Liens levied or placed on or
          threatened against the Collateral, effect any repairs or any insurance
          called for by the terms of this Agreement and pay all or any part of
          the premiums therefor and the costs thereof;


               (d) execute, in connection with any sale provided for in
          subsection 12.4, any endorsements, assignments or other instruments of
          conveyance or transfer with respect to the Collateral; and


               (e) at any time when a Default or an Event of Default has
          occurred and is continuing (1) direct any party liable for any payment
          under any of the Collateral to make payment of any and all moneys due
          or to become due thereunder directly to the Lender or as the Lender
          shall direct; (2) ask or demand for, collect, receive payment of and
          receipt for, any and all moneys, claims and other amounts due or to
          become due at any time in respect of or arising out of any Collateral;
          (3) sign and indorse any invoices, freight or express bills, bills of
          lading, storage or warehouse receipts, drafts against debtors,

          with any of the Collateral; (4) commence and prosecute any suits,
          actions or proceedings at law or in equity in any court of competent
          jurisdiction to collect the Collateral or any thereof and to enforce
          any other right in respect of any Collateral; (5) defend any suit,
          action or proceeding brought against the Borrower with respect to any
          Collateral; (6) settle, compromise or adjust any such suit, action or
          proceeding and, in connection therewith, to give such discharges or
          releases as the Lender may deem appropriate; (7) assign any Copyright,
          Patent or Trademark (along with the goodwill of the business to which
          any such Copyright, Patent or Trademark pertains), throughout the
          world for such term or terms, on such conditions, and in such manner,
          as the Lender shall in its sole discretion determine; and (8)
          generally, sell, transfer, pledge and make any agreement with respect
          to or otherwise deal with any of the Collateral as fully and
          completely as though the Lender were the absolute

          owner thereof for all purposes, and do, at the Lender's option and the
          Borrower's expense, at any time, or from time to time, all acts and
          things which the Lender deems necessary to protect, preserve or
          realize upon the Collateral and the Lender's security interests
          therein and to effect the intent of this Agreement, all as fully and
          effectively as the Borrower might do.


          11.2. PERFORMANCE BY LENDER OF BORROWER'S OBLIGATIONS. If the Borrower
     fails to perform or comply with any of its agreements contained herein, the
     Lender, at its option, but without any obligation so to do, may perform or
     comply, or otherwise cause performance or compliance, with such agreement.


          11.3 BORROWER'S REIMBURSEMENT OBLIGATION. The expenses of the Lender
     incurred in connection with actions undertaken as provided in this Section,
     together with interest thereon at a rate equal to the rate per annum at
     which interest would then be payable on past due ABR Loans under the Credit
     Agreement, from the date of payment by the Lender to the date reimbursed by
     the Borrower, shall be payable by the Borrower to the Lender on demand.


          11.4. RATIFICATION; POWER COUPLED WITH AN INTEREST. The Borrower
     hereby ratifies all that said attorneys shall lawfully do or cause to be

     12. DUTY OF THE LENDER. The Lender's sole duty with respect to the custody,
safekeeping and physical preservation of the Collateral in its possession, under
Section 9-207 of the Code or otherwise, shall be to use reasonable care in the
custody and preservation of such Collateral. Neither the Lender, nor any of its
respective officers, directors, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Borrower or any other Person or to take any
other action whatsoever with regard to the Collateral or any part thereof. The
powers conferred on the Lender hereunder are solely to protect the Lender's
interests in the Collateral and shall not impose any duty upon the Lender to
exercise any such powers. The Lender shall be accountable only for amounts that
its actually receives as a result of the exercise of such powers, and neither it

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

          16.1 AMENDMENTS IN WRITING. None of the terms or provisions of this
     Agreement may be waived, amended, supplemented or otherwise modified except
     by a written instrument executed by the Borrower and the Lender, provided
     that any provision of this Agreement imposing obligations on the Borrower
     may be waived by the Lender in a written instrument executed by the Lender.


          16.2 NO WAIVER BY COURSE OF CONDUCT. The Lender shall not by any act
     (except by a written instrument pursuant to subsection 16.1), delay,
     indulgence, omission or otherwise be deemed to have waived any right or
     remedy hereunder or to have acquiesced in any Default or in any breach of
     any of the terms and conditions hereof. No failure to exercise, nor any
     delay in exercising, on the part of the Lender any right, power or
     privilege hereunder shall operate as a waiver thereof. No single or partial
     exercise of any right, power or privilege hereunder shall preclude any
     other or further exercise thereof or the exercise of any other right, power
     or privilege. A waiver by the Lender of any right or remedy hereunder on
     any one occasion shall not be construed as a bar to any right or remedy
     which the Lender would otherwise have on any future occasion.

     cumulative, may be exercised singly or concurrently and are not exclusive

<PAGE>   3


     2.   PLEDGE; GRANT OF SECURITY INTEREST. The Borrower hereby delivers to 
the Lender, all the Pledged Stock and hereby grants to the Lender, a first
security interest in the Collateral, as collateral security for the prompt and
complete payment and performance when due (whether at the stated maturity, by
acceleration or otherwise) of the Secured Obligations.


     3.   STOCK POWERS. Concurrently with the delivery to the Lender of each
certificate representing one or more shares of Pledged Stock, the Borrower shall
deliver an undated stock power covering such certificate, duly executed in blank
by the Borrower.


     4.   REPRESENTATIONS AND WARRANTIES. The Borrower represents and warrants
that:


     (a) The shares of Pledged Stock constitute all the issued and outstanding
shares of all classes of the capital stock of each Issuer owned by the Borrower.


     (b) All the shares of the Pledged Stock have been duly and validly issued
and are fully paid and nonassessable.


     (c) The Borrower is the record and beneficial owner of, and has good and
marketable title to, the Pledged Stock, free of any and all Liens or options in
favor of, or claims of, any other Person, except the security interest created
by this Agreement.


     (d) Upon delivery to the Lender of the stock certificates evidencing the
Pledged Stock, the security interest created by this Agreement will constitute a
valid, perfected first priority security interest in the Collateral, enforceable
in accordance with its terms against all creditors of the Borrower and any
Persons purporting to purchase any Collateral from the Borrower, except as
affected by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar laws relating to or affecting creditors' rights
generally, general equitable principles (whether considered in a proceeding in
equity or at law) and an implied covenant of good faith and fair dealing.


     5.   COVENANTS. The Borrower covenants and agrees with the Lender that, 
from and after the date of this Agreement until this Agreement is terminated and
the security interests created hereby are released:


     (a) If the Borrower shall, as a result of its ownership of the Pledged
Stock, become entitled to receive or shall receive any stock certificate
(including, without limitation, any certificate representing a stock dividend or
a distribution in connection with any reclassification, increase or reduction of
capital or any certificate issued in connection with any reorganization), option
or rights, whether in addition to, in substitution of, as a conversion of, or in
exchange for any shares of the Pledged Stock, or otherwise in respect thereof,
the Borrower shall accept the same as the agent of the Lender, hold the same in
trust for the Lender and deliver the same forthwith to the Lender in the exact
form received, duly indorsed by the Borrower to the Lender, if required,
together with an undated stock power covering such certificate duly executed in
blank by the Borrower, to be held by the Lender, subject to the terms hereof, as
additional collateral security for the Secured Obligations. At any time when a
Default or an Event of Default has occurred and is continuing, any sums paid
upon or in respect of the Pledged Stock upon the liquidation or dissolution of
any Issuer shall be paid over to the Lender to be held by it hereunder as
additional collateral security for the Secured Obligations, and at any time when
a Default or an Event of Default has 


                                       3
<PAGE>   4


occurred and is continuing, in case any distribution of capital shall be made on
or in respect of the Pledged Stock or any property shall be distributed upon or
with respect to the Pledged Stock pursuant to the recapitalization or
reclassification of the capital of any Issuer or pursuant to the reorganization
thereof, the property so distributed shall be delivered to the Lender to be held
by it hereunder as additional collateral security for the Secured Obligations.
If any sums of money or property so paid or distributed in respect of the
Pledged Stock shall be received by the Borrower, the Borrower shall, until such
money or property is paid or delivered to the Lender, hold such money or
property in trust for the Lender, segregated from other funds of the Borrower,
as additional collateral security for the Secured Obligations.


     (b) Without the prior written consent of the Lender, the Borrower will not
(1) except to the extent not prohibited by the Credit Agreement, vote to enable,
or take any other action to permit, any Issuer to issue any stock or other
equity securities of any nature or to issue any other securities convertible
into or granting the right to purchase or exchange for any stock or other equity
securities of any nature of any Issuer, (2) sell, assign, transfer, exchange, or
otherwise dispose of, or grant any option with respect to, the Collateral, (3)
create, incur or permit to exist any Lien or option in favor of, or any claim of
any Person with respect to, any of the Collateral, or any interest therein,
except for the security interests created by this Agreement or (4) enter into
any agreement or undertaking restricting the right or ability of the Borrower or
the Lender to sell, assign or transfer any of the Collateral.


     (c) The Borrower shall maintain the security interest created by this
Agreement as a first, perfected security interest and shall defend such security
interest against claims and demands of all Persons whomsoever. At any time and
from time to time, upon the written request of the Lender, and at the sole
expense of the Borrower, the Borrower will promptly and duly execute and deliver
such further instruments and documents and take such further actions as the
Lender may reasonably request for the purposes of obtaining or preserving the
full benefits of this Agreement and of the rights and powers herein granted. If
any amount payable under or in connection with any of the Collateral shall be or
become evidenced by any promissory note, other instrument or chattel paper, such
note, instrument or chattel paper shall be immediately delivered to the Lender,
duly endorsed in a manner satisfactory to the Lender, to be held as Collateral
pursuant to this Agreement.


     (d) The Borrower shall pay, and save the Lender harmless from, any and all
liabilities with respect to, or resulting from any delay in paying, any and all
stamp, excise, sales or other taxes which may be payable or determined to be
payable with respect to any of the Collateral or in connection with any of the
transactions contemplated by this Agreement.


     6.   CASH DIVIDENDS; VOTING RIGHTS. Unless a Default or an Event of Default
has occurred and is continuing and the Lender shall have given notice to the
Borrower of the Lender's intent to exercise its corresponding rights pursuant to
Section 7 below (except in the case of a 


                                       4

<PAGE>   5


Bankruptcy Event of Default, in which case no such notice shall be required),
the Borrower shall be permitted to receive all cash dividends paid in the normal
course of business of the Issuers and consistent with past practice, to the
extent permitted in the Credit Agreement, in respect of the Pledged Stock and to
exercise all voting and corporate rights with respect to the Pledged Stock;
provided, however, that no vote shall be cast or corporate right exercised or
other action taken which, in the Lender's reasonable judgment, would impair the
Collateral or which would be inconsistent with or result in any violation of any
provision of the Credit Agreement, the Notes, this Agreement or any other Loan
Document.


     7.   RIGHTS OF THE LENDER. (a) All money Proceeds received by the Lender
hereunder shall be held by the Lender in the Collateral Account. All Proceeds
while held by the Lender in the Collateral Account (or by any Pledgor in trust
for the Lender) shall continue to be held as collateral security for all the
Secured Obligations and shall not constitute payment thereof until applied as
provided in paragraph 8(a) provided that any balance of such proceeds when no
Default is or Event of Default is continuing shall be paid over to the Borrower
or to whomever may be lawfully entitled to receive the same.


     (b) (1) If an Event of Default has occurred and is continuing and the
Lender shall give notice of its intent to exercise such rights to the Borrower
(except in the case of a Bankruptcy Event of Default, in which case no such
notice shall be required), the Lender shall have the right to receive any and
all cash dividends paid in respect of the Pledged Stock and make application
thereof to the Secured Obligations in such order as the Lender may determine,
and (2) if a Default or an Event of Default has occurred and is continuing and
the Lender shall give notice of its intent to exercise such rights to the
Borrower (except in the case of a Bankruptcy Event of Default, in which case no
such notice shall be required), all shares of the Pledged Stock shall be
registered in the name of the Lender or its nominee, and the Lender or its
nominee may thereafter exercise (A) all voting, corporate and other rights
pertaining to such shares of the Pledged Stock at any meeting of shareholders of
any Issuer or otherwise and (B) any and all rights of conversion, exchange,
subscription and any other rights, privileges or options pertaining to such
shares of the Pledged Stock as if it were the absolute owner thereof (including,
without limitation, the right to exchange at its discretion any and all of the
Pledged Stock upon the merger, consolidation, reorganization, recapitalization
or other fundamental change in the corporate structure of any Issuer, or upon
the exercise by the Borrower or the Lender of any right, privilege or option
pertaining to such shares of the Pledged Stock, and in connection therewith, the
right to deposit and deliver any and all of the Pledged Stock with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Lender may determine), all without liability
(to the extent permitted by law) except to account for property actually
received by it, but the Lender shall have no duty to the Borrower to exercise
any such right, privilege or option and shall not be responsible for any failure
to do so or delay in so doing.


     (c) In order to permit the Lender to exercise the voting and other rights
which it is entitled to exercise pursuant to paragraph 7(b)(2) and to receive
the dividends and distributions which it is authorized to receive and retain
pursuant to paragraph 7(b)(1), the Borrower shall, if necessary, upon written
notice from the Lender (except in the case of a 


                                       5
<PAGE>   6


Bankruptcy Event of Default, in which case no such notice shall be required),
from time to time execute and deliver (or cause to be executed and delivered) to
the Lender all such proxies, dividend payment orders and other instruments as
the Lender may reasonably request.


     (d) The rights of the Lender hereunder shall not be conditioned or
contingent upon the pursuit by the Lender of any right or remedy against the
Issuers or against any other Person which may be or become liable in respect of
all or any part of the Secured Obligations or against any collateral security
therefor, guarantee thereof or right of offset with respect thereto. The Lender
shall not be liable for any failure to demand, collect or realize upon all or
any part of the Collateral or for any delay in doing so, nor shall the Lender be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Borrower or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof.


     8.   REMEDIES. (a) If an Event of Default has occurred and is continuing, 
at any time at the Lender's election, the Lender may apply all or any part of
Proceeds held in any Collateral Account in payment of the Secured Obligations in
such order as the Lender may elect.


     (b) If an Event of Default has occurred and is continuing the Lender may
exercise, in addition to all other rights and remedies granted in this Agreement
and in any other instrument or agreement securing, evidencing or relating to the
Secured Obligations, all rights and remedies of a secured party under the Code.
Without limiting the generality of the foregoing, the Lender, without demand of
performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law referred to below) to or upon the
Borrower or any other Person (all and each of which demands, defenses,
advertisements and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, in the over-the-counter market, at any exchange, broker's
board or office of the Lender or elsewhere upon such terms and conditions as it
may deem advisable and at such prices as it may deem best, for cash or on credit
or for future delivery without assumption of any credit risk. The Lender shall
have the right upon any such public sale or sales, and, to the extent permitted
by law, upon any such private sale or sales, to purchase the whole or any part
of the Collateral so sold, free of any right or equity of redemption in the
Borrower, which right or equity is hereby waived or released. The Lender shall
apply any Proceeds from time to time held by it and the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale (after
deducting all reasonable costs and expenses of every kind incurred in respect
thereof or incidental to the care or safekeeping of any of the Collateral or in
any way relating to the Collateral or its rights of the Lender hereunder,
including, without limitation, reasonable attorneys' fees and disbursements of
counsel to the Lender), to the payment in whole or in part of the Secured
Obligations, in such order as the Lender may elect, and only after such
application and after the payment by the Lender of any other amount required by
any provision of law, including, without limitation, Section 9-504(l)(c) of the
Code, need the Lender account for the surplus, if any, to the Borrower. To the
extent permitted by applicable law, the Borrower waives all claims, damages and
demands it may acquire 


                                       6
<PAGE>   7


against the Lender arising out of the exercise by them of any rights hereunder.
If any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition. The Borrower shall remain
liable for any deficiency if the proceeds of any sale or other disposition of
Collateral are insufficient to pay the Secured Obligations and the fees and
disbursements of any attorneys employed by the Lender.


     9.   REGISTRATION RIGHTS; PRIVATE SALES. (a) If the Lender shall determine 
to exercise its right to sell any or all of the Pledged Stock pursuant to 
Section 8 hereof, and if in the opinion of the Lender it is necessary or
advisable to have the Pledged Stock, or that portion thereof to be sold,
registered under the provisions of the Securities Act, the Borrower will cause  
the Issuer thereof to (1) execute and deliver, and cause the directors and
officers of such Issuer to execute and deliver, all such instruments and
documents, and do or cause to be done all such other acts as may be, in the
opinion of the Lender, necessary or advisable to register the Pledged Stock, or
that portion thereof to be sold, under the provisions of the Securities Act, (2)
to use its best efforts to cause the registration statement relating thereto to
become effective and to remain effective for a period of one year from the date
of the first public offering of the Pledged Stock, or that portion thereof to be
sold, and (3) to make all amendments thereto and/or to the related prospectus
which, in the opinion of the Lender, are necessary or advisable, all in
conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto. The
Borrower agrees to cause such Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any and all jurisdictions which the Lender
shall designate and to make available to its security holders, as soon as
practicable, an earnings statement (which need not be audited) which will
satisfy the provisions of Section 11(a) of the Securities Act.


     (b) The Borrower recognizes that the Lender may be unable to effect a
public sale of any or all the Pledged Stock, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof. The Borrower acknowledges and
agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. The Lender shall be under no
obligation to delay a sale of any of the Pledged Stock for the period of time
necessary to permit the Issuer thereof to register such securities for public
sale under the Securities Act, or under applicable state securities laws, even
if such Issuer would agree to do so.


     (c) The Borrower further agrees to use its best efforts to do or cause to
be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged Stock pursuant to this Section valid and
binding and in compliance with any and all other applicable Requirements of Law.
The Borrower further agrees that a breach of any of the covenants contained in
this Section will cause irreparable injury to the Lender and that the Lender 


                                       7
<PAGE>   8


has no adequate remedy at law in respect of such breach and, as a consequence,
that each and every covenant contained in this Section shall be specifically
enforceable against the Borrower, and the Borrower hereby waives and agrees not
to assert any defenses against an action for specific performance of such
covenants except for a defense that no Default or Event of Default had occurred
and was continuing at the time that the Lender gave notice pursuant to paragraph
7(b) hereof.


     10.  IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS. The Borrower
hereby authorizes and instructs each Issuer to comply with any instruction
received by it from the Lender in writing that (a) states that a Default or an
Event of Default has occurred and is continuing and (b) is otherwise in
accordance with the terms of this Agreement, without any other or further
instructions from the Borrower, and the Borrower agrees that each Issuer shall
be fully protected in so complying.


     11.  LENDER'S APPOINTMENT AS ATTORNEY-IN-FACT. (a) The Borrower hereby
irrevocably constitutes and appoints the Lender and any officer or agent of the
Lender, with full power of substitution, as its true and lawful attorney-in-fact
with full irrevocable power and authority in the place and stead of the Borrower
and in the name of the Borrower or in the Lender's own name, from time to time
in the Lender's discretion, for the purpose of carrying out the terms of this
Agreement and to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Agreement, including, without limitation, any financing
statements, endorsements, assignments or other instruments of transfer.


     (b) The Borrower hereby ratifies all that said attorneys shall lawfully do
or cause to be done pursuant to the power of attorney granted in paragraph 11(a)
in accordance with the terms of this Agreement. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.


     12.  DUTY OF LENDER. The Lender's sole duty with respect to the custody,
safekeeping and physical preservation of the Collateral in its possession, under
Section 9-207 of the Code or otherwise, shall be to deal with it in the same
manner as the Lender deals with similar securities and property for its own
account, except that the Lender shall have no obligation to invest funds held in
any Collateral Account and may hold the same as demand deposits. Neither the
Lender, nor any of its respective directors, officers, employees or agents shall
be liable for failure to demand, collect or realize upon any of the Collateral
or for any delay in doing so or shall be under any obligation to sell or
otherwise dispose of any Collateral upon the request of the Borrower or any
other Person or to take any other action whatsoever with regard to the
Collateral or any part thereof.


     13.  EXECUTION OF FINANCING STATEMENTS. Pursuant to Section 9-402 of the
Code, the Borrower authorizes the Lender to file financing statements with
respect to the Collateral without the signature of the Borrower in such form and
in such filing offices as the Lender reasonably determines appropriate to
perfect the security interests of the Lender under this Agreement. A 


                                       8
<PAGE>   9


carbon, photographic or other reproduction of this Agreement shall be sufficient
as a financing statement for filing in any jurisdiction.


     14.  NOTICES. All notices, requests and demands to or upon the Lender or 
the Borrower to be effective shall be in writing (or by fax or similar
electronic transfer confirmed in writing) and shall be deemed to have been duly
given or made (1) when delivered by hand or (2) if given by mail, when deposited
in the mails by certified mail, return receipt requested, or (3) if by fax or
similar electronic transfer, when sent and receipt has been confirmed, addressed
to the Lender or the Borrower at its address or transmission number for notices
provided in the Credit Agreement. The Lender and the Borrower may change their
addresses and transmission numbers for notices by notice in the manner provided
in this Section.


     15.  SEVERABILITY. Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.


     16.  AMENDMENTS IN WRITING; No Waiver; Cumulative Remedies. (a) None of the
terms or provisions of this Agreement may be waived, amended, supplemented or
otherwise modified except by a written instrument executed by the Borrower and
the Lender, provided that any provision of this Agreement may be waived by the
Lender in a letter or agreement executed by the Lender or by facsimile
transmission from the Lender.


     (b) The Lender shall not by any act (except by a written instrument
pursuant to paragraph 16(a) hereof), delay, indulgence, omission or otherwise be
deemed to have waived any right or remedy hereunder or to have acquiesced in any
Default or Event of Default or in any breach of any of the terms and conditions
hereof. No failure to exercise, nor any delay in exercising, on the part of the
Lender, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Lender would otherwise have on any future occasion.


     (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.


     17.  SECTION HEADINGS. The section headings used in this Agreement are for
convenience of reference only and are not to affect the construction hereof or
be taken into consideration in the interpretation hereof.


     18.  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of the Borrower and shall inure to the benefit of the
Lender and its successors and assigns.

             SIGHT RESOURCE OBTAINS NEW $10 MILLION CREDIT FACILITY

(Burlington, Massachusetts)-Sight Resource Corporation (NASDAQ Symbol:
VISN-Common and VISNZ-Warrant), a leading provider of primary eye care services
and innovative managed vision care programs, today announced that it has
obtained a new $10 million credit facility from Creditanstalt Corporate Finance
Inc. of Connecticut.

The credit facility will be used to refinance existing debt, finance future
acquisitions, provide ongoing working capital and for other general corporate
purposes.

When combined with the Company's existing cash balance, the credit facility
provides Sight Resource with approximately $20 million in available capital to
implement its plans.

William G. McLendon, President and Chief Executive Officer stated "The
additional access to capital strengthens our already strong balance sheet and
gives us tremendous flexibility to grow our business and meet the expanding
opportunities in managed vision care. Since we plan to utilize cash to partially
fund acquisitions, this credit facility will help us to meet our growth plans
for 1997."

In the last two years Sight Resource has expanded to include 72 eye care
centers, ten new laser vision correction centers and a managed vision care
program that services third party payor plans with approximately 850,000
enrollees. These business operations have positioned Sight Resource as one of
the twenty largest primary eye care delivery companies in the country and one of
the largest providers of laser vision correction services.

Sight Resource provides a complete range of eye care products and services
through its eye care and laser vision correction centers, its managed vision
care plans and its integrated networks of opticians, optometrists and
ophthalmologists.
