Item 2.  Acquisition or Disposition of Assets.


     On April 22, 1999, a wholly-owned subsidiary of the Registrant, Kent
Acquisition Corporation ("KAC"), completed its acquisition of all of the issued
and outstanding shares of capital stock of Kent Optical Company, a Michigan
corporation ("Kent"), Custom Optics, Inc., a Michigan corporation ("Custom"),
Kent-N.W. Grand Rapids, Inc., a Michigan corporation ("Kent-N.W."), Kent-
Hackley, Inc., a Michigan corporation ("Kent-Hackley"), Source Optical Supply,
Inc., a Michigan corporation ("Source," and collectively with Kent, Custom,
Kent-N.W. and Kent-Hackley, the "Companies"), pursuant to a Stock Purchase and
Sale Agreement (the "Purchase Agreement") by and among KAC, the Registrant, the
Companies and the stockholders of the Companies dated as of April 1, 1999 (the
"Acquisition").  In consideration for all the issued and outstanding stock of
the Companies, KAC paid $5,200,000 in cash provided pursuant to a term loan from
Fleet National Bank, more particularly described in Item 5 to this Form 8-K,
issued promissory notes in the aggregate amount of $1,000,000 and arranged for
the issuance of 160,000 unregistered shares of Common Stock of the Registrant.
The Companies are privately held primary eye care chains that operate eye care
centers in Michigan.  The Registrant intends to continue the business operated
by the Companies.  The purchase price for the Acquisition was determined by
negotiation between the parties based , in part, upon a multiple of the
Companies' earnings.  This Acquisition was accounted for under the purchase
method of accounting.  The Purchase Agreement and the press release dated April
23, 1999, filed as Exhibits 2.1 and 99.8, respectively, are incorporated herein
by reference.



Item 5.  Other Events.

  On April 15, 1999, the Registrant entered into a Loan Agreement (the "Loan
Agreement") with Fleet National Bank (the "Bank") pursuant to which the
Registrant may borrow up to $7,000,000 on a term loan basis, up to $3,000,000 on
a revolving credit basis and up to $10,000,000 on an acquisition credit basis,
subject to certain performance criteria, which loans are secured by all of the
assets of the Registrant and its wholly-owned subsidiaries.

  On April 22, 1999, the Registrant borrowed $7,000,000 pursuant to the term
loan and $975,000 pursuant to the revolving line of credit to refinance existing
debt and finance the acquisition of the Companies by KAC, a wholly owned
subsidiary of the Registrant.  Other amounts borrowed under the Loan Agreement
in the future are expected to be used to finance future acquisitions, provide
ongoing working capital and for other general corporate purposes.

  The Loan Agreement and the press release dated April 23, 1999, filed as
Exhibits 99.1 and 99.9, respectively, are incorporated herein by reference.

     WHEREAS, the Sellers desire to sell the Shares and the Buyer desires to

     WHEREAS, the Buyer, the Companies and the Sellers desire to enter into

     NOW THEREFORE, in consideration of the premises and of the mutual covenants
and agreements contained herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby mutually acknowledged, intending
to be legally bound, the parties hereby agree as follows:


                   ARTICLE I  PURCHASE AND SALE OF THE SHARES
                   ---------  -------------------------------

     SECTION 1.01  Purchase and Sale of the Shares.  On the basis of the
                   -------------------------------                      
representations, warranties and undertakings set forth in this Agreement, and on
the terms and subject to the conditions set forth in this Agreement, at the
Closing (as defined in Section 1.04), each Seller shall sell his, her or its
Shares to the Buyer, and the Buyer shall purchase such Shares from each Seller,
free and clear of all claims, charges, liens, contracts, rights, options,
security interests, mortgages, encumbrances and restrictions of every kind and
nature (collectively, the "Claims").

     SECTION 1.02  Purchase Price.  The purchase price for the Shares (the
                   --------------                                         
"Purchase Price") is the amount per Share set forth on Schedule 1.02, for an
                                                       -------------        
aggregate of $7,000,000 for all of the 

                                       2
<PAGE>
 
Shares, which will be paid as follows: (a) $5,200,000, subject to adjustment
herein, will be paid by wire transfer at the Closing in accordance with
instructions provided by the Sellers (the "Cash Portion"), (b) $175,000 will be
deposited in escrow (the "Escrow Fund") from the proceeds of the Cash Adjustment
(as defined in Section 1.03(b) hereto) pursuant to an escrow agreement (the
"Escrow Agreement") in substantially the form of Exhibit 1.02(a) hereto to
                                                 ---------------
facilitate any adjustment of the Purchase Price pursuant to Section 1.03(a) 
herein, provided, however, in the event that the proceeds of the Cash 
        --------                                
Adjustment (as defined in Section 1.03 hereto) are insufficient to fully 
fund the Escrow Fund, an amount equal to the deficiency in the Escrow
Fund shall be deducted from the Cash Portion and shall be deposited into 
the Escrow Fund pursuant to the Escrow Agreement, (c) Buyer will execute
and deliver a promissory note (the "Note") in the form of Exhibit 1.02(b)
                                                          ---------------
attached hereto to each of Westra and Cress, which together will amount to an
aggregate principal amount of $1,000,000, and (d) Buyer will arrange for the
issuance by SRC to each of Westra and Cress of an amount of shares that will
together amount to an aggregate of 160,000 unregistered shares (the "Payment
Shares") of the Common Stock, par value $.01 per share of SRC (the "SRC Common
Stock"). Unless the per share Market Price, as defined below, reaches $5.00
during any period of time between the first anniversary of the Closing and the
second anniversary of the Closing each of Westra and Cress shall be entitled to
receive additional consideration in an amount equal to (a) the difference
between $5.00 and the greater of (i) the Market Price on the Closing Date or
(ii) the Market Price on the second anniversary of the Closing Date, multiplied
by (b) the number of Payment Shares then held by each of Westra and Cress (the
"Make Whole Payment").  At the Buyer's sole discretion, the Make Whole Payment
may be satisfied by the Buyer in cash or by the issuance of additional
unregistered shares of SRC Common Stock valued at the Market Price on the second
anniversary of the Closing Date and equal to the cash value of the Make Whole
Payment (the "Make Whole Shares").  In the event that the Make Whole Payment is
satisfied by Make Whole Shares and unless the per share Market Price reaches
$5.00 during any period of time between the third anniversary of the Closing and
the fourth anniversary of the Closing, each of Westra and Cress shall be
entitled to receive additional consideration in the form of a cash payment (the
"Second Make Whole Payment"), equal to (x) the difference between $5.00 and the
greater of (A) the Market Price on the Closing Date or (B) the Market Price on
the fourth anniversary of the Closing Date, multiplied by (y) the number of
Payment Shares and Make Whole Shares then held by each of Westra and Cress;
provided, however, the Second Make Whole Payment shall not exceed an aggregate
of fifty thousand dollars ($50,000) to each of Westra and Cress.  In the event
that (1) either of Westra or Cress sell Payment Shares or Make Whole Shares at a
per share purchase price in excess of $5.00 or (2) the per share market price of
the SRC Common Stock exceeds $5.00 at any time between the first anniversary of
the Closing and the second anniversary of the Closing or between the third
anniversary of the Closing and the fourth anniversary of the Closing, then any
Make Whole Payment or Second Make Whole Payment shall be reduced in accordance
with the calculations set forth below.  In the case of (1) above, the Make Whole
Payment or Second Make Whole Payment, as applicable, shall be reduced by an
amount equal to (i) the difference between the per share purchase price and
$5.00 multiplied by (ii) the number of Payment Shares or Make Whole Shares sold.
In the case of (2) above and if no Payment Shares or Make Whole Shares are sold,
then the Make Whole Payment or Second Make Whole Payment, as applicable, shall
be reduced by an amount equal to  (i) the difference between the highest per
share market price at any time between the first anniversary of the Closing and
the second anniversary of the Closing, in the case of the Make Whole Payment, or

                                       3
<PAGE>
 
between the third anniversary of the Closing and the fourth anniversary of the
Closing, in the case of the Second Make Whole Payment, and $5.00 multiplied by
(ii) the number of Payment Shares or Make Whole Shares then held by each of
Westra and Cress, as applicable. "Market Price" shall mean the average of the
closing prices (or, if there is no closing price, then the average of the daily
bid and asked prices) of the SRC Common Stock on the Nasdaq National Market
System ("NASDAQ") (or on any exchange on which the SRC Common Stock is then
traded) for the period of twenty (20) consecutive trading days ending two
business days prior to the applicable date of measurement.


  SECTION 1.03  Purchase Price Adjustments.
                -------------------------- 

(a)  The parties acknowledge and agree that the Purchase Price has been
     established with reference in part to the Net Worth (as defined below) and
     aggregate Cash and Short Term Investments (as defined below) of the
     Companies as of December 31, 1998, as reflected on the Base Balance Sheet
     (as defined in Section 2.09 herein).  As promptly as practicable, but in
     any event within sixty (60) days after the Closing, the Buyer shall deliver
     to the Sellers a statement of the Net Worth as of the Closing Date and Cash
     and Short Term Investments of the Companies determined by the average of
     the Cash and Short Term Investments as of March 31, 1999 and April 30, 1999
     (the "Closing Statement"), which shall be prepared by the Buyer in
     accordance with OCBOA (as defined in Section 2.09 herein) on a basis
     consistent with the Base Balance Sheet and shall be audited and reported on
     by KPMG Peat Marwick LLP ("Buyer's Accountant").  For purposes of this
     Agreement, the term "Net Worth" shall mean total assets less total
     liabilities, and the term "Cash and Short Term Investments" shall mean
     cash, money market and short term investments.

  The Closing Statement shall be conclusive and binding upon the parties hereto,
unless the Sellers object in writing to any item or items shown on the Closing
Statement within fifteen (15) business days after delivery to the Sellers of the
Closing Statement (the "Objection Period").  During the Objection Period, the
Sellers may request that all work papers of Buyer's Accountant which were used
in the preparation of the Closing Statement be mailed or, to the extent
commercially reasonable, transmitted by facsimile to Sellers' accountants.  If
Buyer and the Sellers shall be unable to resolve any dispute with respect to the
Closing Statement within twenty (20) business days after delivery of the
Sellers' written objections, the matter or matters in dispute shall be submitted
(at the equal expense of Buyer and the Sellers) to such firm of independent
certified public accountants as Buyer on the one hand and the Sellers on the
other hand may mutually agree.  The decision of such firm of independent
certified public accountants shall be conclusive and binding upon Buyer and
Sellers.

  (i) If the Net Worth of the Companies as of the Closing Date conclusively
determined as set forth above is less than $800,000 there shall be refunded to
Buyer from the Escrow Fund in accordance with the terms of the Escrow Agreement
an amount equal to the difference between $800,000 and the Net Worth as stated
on the Closing Statement together with all interest earned thereon and (ii) if
the Cash and Short Term Investments held by the Companies as determined by the
average of the Cash and Short Term Investments as of March 31, 1999 and April
30, 1999 conclusively determined as set forth above is less than $125,000 there
shall be refunded to Buyer 

                                       4
<PAGE>
 
from the Escrow Fund in accordance with the terms of the Escrow Agreement an
amount equal to the difference between $125,000 and the Cash and Short Term
Investments as stated on the Closing Statement together with all interest earned
thereon. If such difference exceeds the amount of the Escrow Fund, the Sellers
shall refund to Buyer the amount held in the Escrow Fund and promptly pay to
Buyer the amount of such excess by wire transfer of immediately available funds
to an account designated by Buyer.

(b)  If the Cash and Short Term Investments held by the Companies as determined
     by the average of the Cash and Short Term Investments as of March 31, 1999
     and April 30, 1999 is projected to exceed $125,000 (such projection to
     occur two business days prior to Closing), then the Cash Portion of the
     Purchase Price shall be increased by the aggregate amount of fifty percent
     of the Cash and Short Term Investments projected to exceed $125,000 (the
     "Cash Adjustment"); provided, however, any such Cash Adjustment shall be
     subject to adjustment in accordance with provisions of Section 1.03(a)
     herein and provided, further, that the first $175,000 of the Cash
     Adjustment shall be deposited in the Escrow Fund pursuant to the Escrow
     Agreement.

  SECTION 1.04  Closing.  Subject to the satisfaction or waiver by the parties
                -------

the parties (such date and time being referred to as the "Closing Date").   At
the Closing, in addition to the satisfaction or waiver of each of the conditions
set forth in Articles VII and VIII herein, the parties shall deliver such
further documents, resolutions, certificates and instruments as any party or

  SECTION 2.09  Financial Statements.  The Companies have previously furnished
                --------------------                                          
to the Buyer, and attached hereto as Schedule 2.09, the final combined balance
                                     -------------

"Balance Sheet Date"), as at December 31, 1997 and as at December 31, 1996 and
any related statements of income and cash flow and notes thereto.  All such
financial statements (the "Financial Statements") have been prepared in
accordance with a version of the Other Comprehensive Basis of Accounting
("OCBOA") that is generally a tax basis of accounting used by the Companies to
file their income tax returns on an accrual basis, consistently applied.  The
Financial Statements were prepared from the books and records of each of the
Companies, which books and records are complete and correct and accurately
reflect all transactions of each of the Companies' businesses.  The Financial
Statements fairly present the financial position of each of the Companies as of
the dates thereof, and the results of its operations and cash flows for the
periods ended on the dates thereof.  The Financial Statements reflect reserves
appropriate and adequate for all known material liabilities and reasonably
anticipated losses consistent with the requirements of OCBOA, consistently
applied.  Since the date of the Base Balance Sheet, (a) there has been no change
in the assets, liabilities or financial condition of the assets of any of the
Companies from that reflected in the Base Balance Sheet except for changes in
the ordinary course of business consistent with past practice and which have not

condition, operations, property or affairs of any of the Companies has been
materially or adversely affected by any occurrence or development, individually

Sheet, none of the Companies has any liabilities or obligations of any nature
whatsoever, due or to become due, accrued, absolute, contingent or otherwise
except for liabilities and obligations incurred since the date of the Base
Balance Sheet in the ordinary course of business and consistent with past
practice.  The Sellers do not know of, and have no reason to know of, any basis
for the assertion against any of the Companies of any liability or obligation
not fully reflected or reserved against in the Base Balance Sheet or incurred in
the ordinary course of business and consistent with past practice since the date
thereof.  None of the Companies is bound by any agreement, or subject to any
charter or other corporate restriction or any legal requirement, which has, or

past practice, there have been no material adverse changes in the businesses of
the Companies and there are no known conditions or developments or contingencies

                         days, provided that the party seeking termination is
                         not in material breach of any of its representations,
                         warranties or covenants hereunder.

          C. By the Buyer if:

                   (i)   Any of the conditions set forth in Article VII hereof
                         has not been satisfied on or before April 23, 1999 or
                         shall have become incapable of fulfillment and shall
                         not have been waived by the Buyer, for any reason other
                         than a breach by the Buyer of any of its
                         representations, warranties or agreements hereunder; or

                   (ii)  If in the Buyer's good faith judgment there is any
                         inaccuracy in any representations or breach of any
                         warranty contained 

                                       27
<PAGE>
 
                         therein, or any failure by the Seller to perform any
                         commitment, covenant or condition contained in this
                         Agreement, or there exists any error, misstatement or
                         omission with regard to any of the Exhibits, Schedules
                         or other documents referred to herein, or the Buyer in
                         its sole judgment is not satisfied with the results of
                         its investigation or the contents of any of the
                         Exhibits, Schedules, information or other documents, or
                         with the results of its examination of the business and
                         condition (financial or otherwise) of any of the
                         Companies.

               D. By the Sellers if any of the conditions set forth in Article
     VIII hereof has not been satisfied on or before April 23, 1999, or shall
     have become incapable of fulfillment and shall not have been waived by the
     Sellers, for any reason other than a breach by any Seller of any of their
     representations, warranties or agreements hereunder;

     Upon the occurrence of any of the events specified in this Section 10.01
(other than paragraph A hereof), written notice of such event shall forthwith be
given to the other parties to this Agreement, whereupon this Agreement shall
terminate.

     SECTION 10.02  Effect of Termination.  In the event of the termination and
                    ---------------------                                      
abandonment of this Agreement pursuant to Section 10.01, this Agreement, except
for the provisions of Articles  IX, X and XI shall forthwith become void and be
of no effect, without any liability on the part of any party or its directors,
officers or shareholders.  Nothing in this Section 10.02 shall relieve any party
to this Agreement of liability for breach of this Agreement.

     If the Sellers or any of the Companies fails to fulfill its obligations
hereunder for any reason not excused by an express provision of this Agreement,
then the Buyer shall, in addition to any other remedies that it may have, have
the right to bring an action in any court of competent jurisdiction to obtain
specific performance of this Agreement, it being understood that the parties
agree that failure of the Sellers to consummate the purchase and sale of the
Shares or failure of the Sellers or any of the Companies to perform any of their
obligations contemplated by this Agreement (except for a failure excused by an
express provision of this Agreement) would cause irreparable injury to the Buyer
and that money damages would not provide an adequate remedy to the Buyer.  The
Sellers and each of the Companies therefore waive all objections to the award of
equitable relief for such failure.


                           ARTICLE XI  SRC GUARANTEE
                           ----------  -------------

     SECTION 11.01  Guarantee.
                    --------- 

          (a) SRC hereby irrevocably and unconditionally guarantees (the
"Guarantee") to the Sellers the obligations of the Buyer under the Notes, the
Make Whole Payment, the Second Make Whole Payment and the payment obligations of
the Employment Agreements (each an 

                                       28
<PAGE>
 
"Obligation" and collectively the "Obligations"). Failing payment when due of
any amount so guaranteed for whatever reason, SRC shall be obligated, to pay the
same.

          (b) SRC hereby agrees, to the fullest extent permitted by applicable
law, that its obligations with regard to this Guarantee shall be unconditional.
SRC hereby waives diligence, presentment, demand of payment, filing of claims
with a court in the event of insolvency or bankruptcy of the Buyer, any right to
require a proceeding first against the Buyer or right to require the prior
disposition of the assets of the Buyer to meet its obligations, protest, notice
and all demands whatsoever and covenants that this Guarantee will not be
discharged (except to the extent released pursuant to Section 11.02 herein)
except by complete performance of the Obligations.

          (c) It is the intention of SRC and the Buyer that the Obligations
shall not be in excess of the maximum amount permitted by applicable law.
Accordingly, if the obligations in respect of the Guarantee would be annulled,
avoided or subordinated to the creditors of SRC by a court of competent
jurisdiction in a proceeding actually pending before such court as a result of a
determination both that such Guarantee was made by SRC without fair
consideration and, immediately after giving effort thereto, SRC was insolvent or
unable to pay its debts as they mature or left with an unreasonably small
capital, then the obligations of SRC under such Guarantee shall be reduced by
such court if and to the extent such reduction would result in the avoidance of
such annulment, avoidance or subordination.  For purposes of this paragraph,
"fair consideration," "insolvency," "unable to pay its debts as they mature,"
"unreasonably small capital" and the effective times of reductions, if any,
required by this paragraph shall be determined in accordance with applicable
law.

     SECTION 11.02  Reserved.
                    -------- 


     SECTION 11.03  Certain Bankruptcy Events.
                    ------------------------- 

     SRC hereby covenants and agrees, to the fullest extent that it may do so
under applicable law, that in the event of the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Buyer, SRC shall not file (or
join in any filing of), or otherwise seek to participate in the filing of, any
motion or request seeking to stay or to prohibit (even temporarily) execution on
the Guarantee and hereby waives and agrees not to take the benefit of any such
stay or execution, whether the bankruptcy law permits or otherwise.


                           ARTICLE XII  MISCELLANEOUS
                           -----------  -------------

     SECTION 12.02  Entire Agreement.  This Agreement together with the Exhibits
                    ----------------                                            
and Schedules hereto and the other documents executed in connection herewith
(together, the "Documents") embodies the entire agreement and understanding
between the parties hereto with respect to the subject matter hereof and
supersedes all prior oral or written agreements and understandings relating to
the subject matter hereof.  No statement, representation, warranty, covenant or
agreement of any kind not expressly set forth in the Documents shall affect, or
be used to interpret, change or restrict, the express terms and provisions of
this Agreement.

     SECTION 12.03  Modifications and Amendments.  The terms and provisions of
                    ----------------------------                              
this Agreement may be modified or amended only by written agreement executed by
all parties hereto.

     SECTION 12.04  Waivers and Consents.  No failure or delay by a party hereto
                    --------------------                                        
in exercising any right, power or remedy under this Agreement, and no course of
dealing between the parties hereto, shall operate as a waiver of any such right,
power or remedy of the party.  No single or partial exercise of any right, power
or remedy under this Agreement by a party hereto, nor any abandonment or
discontinuance of steps to enforce any such right, power or remedy, shall
preclude such party from any other or further exercise thereof or the exercise
of any other right, power or

                                       30
<PAGE>
 
remedy hereunder. The election of any remedy by a party hereto shall not
constitute a waiver of the right of such party to pursue other available
remedies. No notice to or demand on a party not expressly required under this
Agreement shall entitle the party receiving such notice or demand to any other
or further notice or demand in similar or other circumstances or constitute a
waiver of the rights of the party giving such notice or demand to any other or
further action in any circumstances without such notice or demand. The terms and
provisions of this Agreement may be waived, or consent for the departure
therefrom granted, only by written document executed by the party entitled to
the benefits of such terms or provisions. No such waiver or consent shall be
deemed to be or shall constitute a waiver or consent with respect to any other
terms or provisions of this Agreement, whether or not similar. Each such waiver
or consent shall be effective only in the specific instance and for the purpose
for which it was given, and shall not constitute a continuing waiver or consent.

     SECTION 12.05  Assignment.  Neither this Agreement, nor any right
                    ----------                                        
hereunder, may be assigned by any of the parties hereto without the prior
written consent of the other parties, except that the Buyer may assign all or
part of its rights and obligations under this Agreement to one or more direct or
indirect subsidiaries or affiliates (in which event, representations and
warranties relating to the Buyer shall be appropriately modified).

     SECTION 12.06  Parties in Interest.  This Agreement shall be binding upon
                    -------------------                                       
and inure solely to the benefit of each party hereto and their permitted
assigns, and nothing in this Agreement, express or implied, is intended to
confer upon any other person any rights or remedies of any nature whatsoever
under or by reason of this Agreement.  Nothing in this Agreement shall be
construed to create any rights or obligations except among the parties hereto,
and no person or entity shall be regarded as a third-party beneficiary of this
Agreement.

     SECTION 12.07  Governing Law.  This Agreement and the rights and
                    -------------                                    
obligations of the parties hereunder shall be construed in accordance with and
governed by the internal laws of the State of Michigan, without giving effect to
the conflict of law principles thereof.

     SECTION 12.08  Arbitration.  Any controversy, dispute or claim arising out
                    -----------                                                
of or in connection with this Agreement, or the breach, termination or validity
hereof, shall be settled by final and binding arbitration, to be conducted in
the first instance in Boston, Massachusetts, in the second instance in Grand
Rapids, Michigan and thereafter alternating between such locations, pursuant to
the then-obtaining Commercial Rules of the American Arbitration Association.
The decision or award of the arbitration panel shall be final, and judgment upon
such decision or award may be entered in any competent court or application may
be made to any competent court for judicial acceptance of such decision or award
and an order of enforcement.  The arbitration panel shall allocate the costs of
the arbitration to any of the parties as it sees fit, and shall have the
discretion to require a party to pay the attorney's fees incurred by another
party in connection with the arbitration.

     SECTION 12.09  Severability.  In the event that any court of competent
                    ------------                                           
jurisdiction shall finally determine that any provision, or any portion thereof,
contained in this Agreement shall be void or unenforceable in any respect, then
such provision shall be deemed limited to the extent that 

                                       31
<PAGE>
 
such court determines it enforceable, and as so limited shall remain in full
force and effect. In the event that such court shall determine any such
provision, or portion thereof, wholly unenforceable, the remaining provisions of
this Agreement shall nevertheless remain in full force and effect.

     SECTION 12.10  Interpretation.  The parties hereto acknowledge and agree
                    --------------                                           
that: (a) each party and its counsel reviewed and negotiated the terms and
provisions of this Agreement (except with respect to the disclosure schedules
regarding the business of the Companies which are the sole responsibility of the
Sellers) and have contributed to its revision; (b) the rule of construction to
the effect that any ambiguities are resolved against the drafting party shall
not be employed in the interpretation of this Agreement; and (c) the terms and
provisions of this Agreement shall be construed fairly as to all parties hereto
and not in favor of or against any party, regardless of which party was
generally responsible for the preparation of this Agreement.

     SECTION 12.11  Headings and Captions.  The headings and captions of the
                    ---------------------                                   
various subdivisions of this Agreement are for convenience of reference only and
shall in no way modify, or affect, or be considered in construing or
interpreting the meaning or construction of any of the terms or provisions
hereof.

     SECTION 12.12  Enforcement.  Each of the parties hereto acknowledges and
                    -----------                                              
agrees that the rights acquired by each party hereunder are unique and that
irreparable damage would occur in the event that any of the provisions of this
Agreement to be performed by the other party were not performed in accordance
with their specific terms or were otherwise breached.  Accordingly, in addition
to any other remedy to which the parties hereto are entitled at law or in
equity, each party hereto shall be entitled to an injunction or injunctions to
prevent breaches of this Agreement by the other party and to enforce
specifically the terms and provisions hereof in any federal or state court to
which the parties have agreed hereunder to submit to jurisdiction.

     SECTION 12.13  Reliance.  The parties hereto agree that, notwithstanding
                    --------                                                 
any right of any party to this Agreement to investigate the affairs of any other
party to this Agreement, the party having such right to investigate shall have
the right to rely fully upon the representations and warranties of the other
party expressly contained in this Agreement and on the accuracy of any schedule
or other document attached hereto or referred to herein or delivered by such
other party or pursuant to this Agreement.

     SECTION 12.14  Expenses.  Each of the parties hereto shall pay its own fees
                    --------                                                    
and expenses (including the fees of any attorneys, accountants, appraisers or
others engaged by such party) in connection with this Agreement and the
transactions contemplated hereby whether or not the transactions contemplated
hereby are consummated; provided, however, that all expenses in excess of
                        --------                                         
$25,000 billed to or incurred by each of the Companies in connection with this
Agreement and the transactions contemplated hereby after March 1, 1999 shall be
borne by the Sellers and not the Companies.

     SECTION 12.15  No Broker or Finder.  Each of the parties hereto represents
                    -------------------                                        
and warrants to the other that no broker, finder or other financial consultant
has acted on its behalf in connection with this Agreement or the transactions
contemplated hereby in such a way as to create any liability 

                                       32
<PAGE>
 
on the other. Each of the parties hereto agrees to indemnify and save the other
harmless from any claim or demand for commission or other compensation by any
broker, finder, financial consultant or similar agent claiming to have been
employed by or on behalf of such party and to bear the cost of legal expenses
incurred in defending against any such claim.

     SECTION 12.16  Publicity.  No party shall issue any press release or
                    ---------                                            
otherwise make any public statement with respect to the execution of, or the
transactions contemplated by, this Agreement without the prior written consent
of the other party, except as may be required by law.  The parties recognize
that the Buyer is a subsidiary of a publicly held company which is obligated
under the federal or state securities laws, rules or regulations to make
disclosures of material events affecting it.  Upon advice by counsel that Buyer
or SRC is required to make such an announcement by the federal or state
securities laws, rules or regulations, Buyer or SRC may make such announcement.
Buyer agrees to promptly inform each of the Companies of such advice and, if
practicable, give each of the Companies an opportunity to comment upon the form
of any such announcement.

     SECTION 12.17  Confidentiality.  Each party acknowledges and agrees that
                    ---------------                                          
any information or data it has acquired from the other party, not otherwise
properly in the public domain, was received in confidence.  Each party hereto
agrees not to divulge, communicate or disclose, except as may be required by law
or for the performance of this Agreement (including obtaining financing and
conducting due diligence), or use to the detriment of the disclosing party or
for the benefit of any other person or persons, or misuse in any way, any
confidential information of the disclosing party concerning the subject matter
hereof, including any trade or business secrets of the disclosing party and any
technical or business materials that are treated by the disclosing party as
confidential or proprietary, including without limitation information (whether
in written, oral or machine-readable form) concerning:  general business
operations; methods of doing business, servicing clients, client relations, and
of pricing and making charge for services and products; financial information,
including costs, profits and sales; marketing strategies; business forms
developed by or for the disclosing party; names of suppliers, personnel,
customers, clients and potential clients; negotiations or other business
contacts with suppliers, personnel, customers, clients and potential clients;
form and content of bids, proposals and contracts; the disclosing party's
internal reporting methods; technical and business data, documentation and

disclosing party about or belonging to third parties.

     SECTION 12.18  Counterparts.  This Agreement may be executed in one or more
                    ------------                                                
counterparts, and by different parties hereto on separate counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

                (90) days from the invoice date thereof, plus

           (ii) the lesser of: (x) $2,000,000.00 or (y) thirty percent (30%) of
                the value (determined at the lower of cost or market value) of
                the sum of the Eligible current Inventory of each Borrower (the
                sum of (i) plus (ii) is hereinafter called the "Borrowing 
                Base").

     2.02  If at any time the aggregate Advances under the Revolving Loan exceed
the Borrowing Base, the Borrower shall immediately, on demand, pay to the Bank
an amount sufficient to reduce the aggregate amount of such Advances to an
amount less than the Borrowing Base.

     2.03  For purposes of the Borrowing Base calculation set forth above,
Eligible Accounts Receivable are those which are owing to the Borrower which met
the following specifications at the time it came into existence and continues to
meet the same until collected in full:

           (i)   The account arose from the performance of services or an 
                 outright sale of goods by Borrower, such goods have been
                 shipped to the account debtor, and Borrower has possession of,
                 or has delivered to Bank, shipping and delivery receipts
                 evidencing such shipment.

          (ii)   The account is not subject to any prior assignment, claim, 
                 lien, or security interest, and Borrower will not make any
                 further assignment thereof or create any further security
                 interest therein (except in favor of Bank) nor permit
                 Borrower's rights therein to be reached by attachment, levy,
                 garnishment or other judicial process.

          (iii)  The account is not subject to set-off, credit, allowance or
                 adjustment by the account debtor, except discount allowed for
                 prompt payment and the account debtor has not complained as to
                 its liability thereon and has not returned any of the goods
                 from the sale of which the account arose.

           (iv)  The account arose in the ordinary course of Borrower's business
                 and did not arise from the performance of services or a sale of
                 goods to a supplier or employee of the Borrower.

           (v)   No notice of bankruptcy or insolvency of the account debtor has
                 been received by or is actually known by the Borrower.

           (vi)  The account is not owed by an account debtor whose principal
                 place of business is outside the United States of America,
                 unless such account is supported by a letter of credit
                 reasonably acceptable to the Bank in all respects.

          (vii)  The account is not owed by an entity which is a parent,
                 brother/sister, subsidiary or affiliate of any of the entities
                 constituting the Borrower.

          (viii) The account debtor is not located in the State of New Jersey
                 or Minnesota unless Borrower has filed and shall file all
                 legally required Notice of Business Activities Report(s) with
                 the New Jersey Division of Taxation or the Minnesota Department
                 of Revenue.

           (ix)  The account is not evidenced by a promissory note.

                                       7
<PAGE>
 
           (x)   The account did not arise out of any sale made on a bill and
                 hold, dating or delayed shipment basis.

           (xi)  The account did not arise out of a contract with the United
                 States government or any department, agency or instrumentality
                 thereof, unless the Borrower has complied with the Federal
                 Assignment of Claims Act.

           (xii) The Bank in its reasonable banking judgement exercised in good
                 faith does not deem the account to be unacceptable for any
                 reason.

     2.04  For purposes of the Borrowing Base calculations set forth above,
Eligible Inventory means Borrower's finished goods which are initially and at
all times until sold new and unused, in first-class condition, merchantable and
saleable through normal trade channels; at a location which has been identified
in writing to the Bank; subject to a perfected security interest in favor of
Bank; owned by Borrower free and clear of any lien except in favor of Bank; not
obsolete; not scrap, waste, defective goods and the like; have been produced by
Borrower in accordance with the Federal Fair Labor Standards Act of 1938, as
amended, and all rules, regulations and orders promulgated thereunder; and have
not been designated by Bank in its reasonable banking judgement exercised in
good faith as unacceptable for any reason upon notice to Borrower.

     2.05  Bank shall not be required to make an Advance under the Revolving
Loan unless Bank shall have received from the Borrower a request in the form of
Exhibit A attached hereto for such Advance (herein a "Notice of Borrowing"),
which request complies with the requirements of this Section 2.05.  Each Notice
of Borrowing shall designate (a) the Borrowing Date for the requested Advance,
(b) the amount of the Advance, which amount shall be no less than One Hundred
Thousand ($100,000.00) Dollars if the Advance will be a Libor Loan, and provided
that no more than eight (8) Libor Loans shall be outstanding at any one time;
and (c) if such Notice of Borrowing requests a Libor Loan, it must state the
Interest Period.  Each Notice of Borrowing must be received by Bank (x) before
12:00 p.m. (Boston time) on the designated Borrowing Date if the Advance will be
a Prime Rate Loan; and (y) not less than two Banking Days prior to the Borrowing
Date if the Advance will be a Libor Loan.  A Notice of Borrowing may be
transmitted by telephone, telecopier, telex, cable, overnight courier, hand
delivery or mail.  If a Notice of Borrowing is transmitted by telephone,
telecopier, telex, or cable, the Borrower shall immediately mail to Bank written
confirmation thereof.

     2.06  After receipt from the Borrower of any Notice of Borrowing which
requests a Libor Loan, Bank shall determine if it is able to make such Advance
(or if it is unable to do so for reasons described in this Section 2.06 only)
and will notify the Borrower upon confirmation of its ability to do so.  If Bank
determines in good faith that, by reason of circumstances affecting the
Interbank Market, adequate and reasonable methods do not exist for ascertaining
the Libor which would otherwise be applicable to such Advance then Bank shall so
notify the Borrower on or before 4:00 p.m. on the Banking Day prior to the
Borrowing Date specified in the Notice of Borrowing, and in such event, Bank
shall not be obligated to make such Advance and the Notice of Borrowing shall be
deemed to have been withdrawn by the Borrower with Bank's consent and
substituted with a request for a Prime Rate Loan in an amount equal to the
requested Libor Loan.

                                       8

     2.07  Except as otherwise provided in Section 2.06 above, any Notice of
Borrowing requesting a Libor Loan shall be irrevocable and binding upon the
Borrower.  In the event the Borrower fails to borrow the Advance requested on
the Borrowing Date specified in such Notice of Borrowing, the Borrower shall
indemnify Bank against any and all losses and reasonable expenses incurred by
Bank by reason of such failure including, without limiting the generality of the
foregoing, all losses and reasonable expenses incurred by reason of the
liquidation, disposition or reemployment of deposits or other funds acquired by
Bank to fund such Advance including, without limitation, compensation provided
for in Section 2.24 of this Agreement.

     2.08  All net proceeds of each Advance shall be credited to any demand
deposit account maintained by the Borrower with Bank or the loan account
established pursuant to this Revolving Loan (the "Loan Account"), the specified
amount and account to be designated by the Borrower in the Notice of Borrowing
issued with respect to such Advance.
 
     2.09  No Advances of new money shall be available to the Borrower after the
Termination Date.

     2.10  The Borrower shall pay interest on the unpaid principal balance of
each Prime Rate Loan from the Borrowing Date for such Advance at a variable per
annum rate equal to the Prime Rate in effect from time to time.  Interest
accrued under this Section 2.10 shall be paid monthly in arrears on each
Interest Payment Date.

     2.11  The Borrower shall pay interest on the aggregate unpaid principal
balance of each Libor Loan from the Borrowing Date for such Advance through and
including the Maturity Date chosen by the Borrower with respect to such Advance
at a per annum rate equal to the aggregate of the Adjusted Libor plus Margin,
and shall pay all interest accrued but unpaid under this Section 2.11 on the
sooner to occur of the Interest Payment Date or such Maturity Date.

     2.12  If a Libor Loan is not repaid in full on its Maturity Date, then such
Advance shall bear interest at the rate described in Section 2.10 from and after
such Maturity Date through the Termination Date and thereafter, as set forth in
Section 2.13 until paid in full.
 
     2.13  From and after the occurrence of an Event of Default and acceleration
of the Borrower's Obligations to the Bank under this Agreement, at the option of
the Bank: (a) all Prime Rate Loans shall bear interest at a variable per annum
rate equal to the aggregate of the Prime Rate in effect from time to time plus
four percent (4%) until paid in full; and (b) each Libor Loan shall bear
interest at the rate established therefor pursuant to Section 2.11 until such
Advance's Maturity Date, and thereafter at the rate set forth in clause (a) of
this Section 2.13 until paid in full.

     2.14  Each rate of interest determined hereunder by reference to the Prime
Rate shall change effective as of the opening of business on each day on which a
change in the Prime Rate becomes effective.

     2.15  All interest, fees and other charges payable under this Agreement
shall be computed on the basis of a year of three hundred sixty (360) days for
the actual number of days elapsed.

                                       9

     2.16  If the Bank shall have determined in good faith at its reasonable
discretion that the adoption of any applicable law, rule or regulation regarding
capital requirements for banks or bank holding companies, or any change therein,
or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Bank with any
request or directive of such entity regarding capital adequacy (whether or not
having the force of law) has the effect of reducing the return on the Bank's
capital to a level below that which the Bank could have achieved (taking into
consideration the Bank's policies with respect to capital adequacy immediately
before such adoption, change or compliance and assuming that the Bank's capital
was fully utilized prior to such adoption, change or compliance) but for such
adoption, change or compliance as a consequence of its commitment to make
Advances hereunder by any amount deemed by the Bank in good faith to be
material:

     (i)   the Bank shall promptly after its determination of such occurrence
           give written notice thereof to the Borrower; and

     (ii)  the Borrower shall pay to the Bank as an additional fee from time to
           time on demand such amount as the Bank certifies to be the amount
           that will reasonably compensate it for such reduction (attributable
           to the Credit Limit under this Agreement).

     A certificate of the Bank claiming compensation under this Section 2.16
shall be conclusive in the absence of manifest error.  Such certificate shall
set forth the nature of the occurrence giving rise to such compensation, the
additional amount or amounts to be paid to it hereunder and the method by which
amounts were determined.  In determining such amount, the Bank may use any
reasonable averaging and attribution methods.

     2.17  In consideration of the Bank establishing the Revolving Loan, the
Borrower shall pay the Bank a fee equal to one-quarter of one (.25%) percent of
the Credit Limit, such fee to be payable at closing and on the anniversary date
of the closing in each year that the Revolving Loan remains in effect.
 
     2.18  Any Prime Rate Loan may be repaid in whole or in part at any time
without premium or penalty.

     2.19  Each Libor Loan shall be repaid in full on its Maturity Date.

     2.20  Except as otherwise provided herein with respect to Bank's rights
following the occurrence of an Event of Default, no Libor Loan may be repaid
prior to its Maturity Date unless Borrower shall indemnify Bank for all losses
and reasonable expenses resulting from such prepayment as more particularly
described in Section 2.07 hereof.

     2.21  Any Advance under the Revolving Loan (whether a Prime Rate Loan or a
Libor Loan) may be repaid with the proceeds of another Advance under the
Revolving Loan (whether a Prime Rate Loan or a Libor Loan), subject to the terms
of Section 2.01.  Accordingly, the Borrower may convert a Prime Rate Loan to a
Libor Loan, a Libor Loan to a Prime Rate Loan, Prime Rate Loans may be repaid
with the proceeds of another Prime Rate Loan and a Libor Loan may be repaid with
the proceeds of another Libor Loan, but in all cases subject to the terms of
Section 2.01 hereof.

     2.22  Borrower hereby authorizes and directs Bank to pay all principal,
interest, fees, and other charges due from Borrower to Bank hereunder by (i)
charging such amounts against any general demand deposit account of the Borrower
maintained with the Bank as a condition for establishing the financing
arrangements with the Borrower; or (ii) debiting the Loan Account in the amount
of such sums due and treating the same as an Advance to the Borrower under the
Revolving Loan, which Advance shall accrue interest as a Prime Rate Loan;
provided, however, the Bank shall have no obligation to do so unless (i)
sufficient funds are on deposit in such demand deposit accounts; and/or (ii)
such Advance would not exceed the lesser of the Borrowing Base or the Commitment
Amount and/or (iii) no Default exists.  The provisions of this Section 2.22
shall not limit the rights of the Bank under Section 2.24 of this Agreement or
the obligation of the Borrower to pay interest as provided elsewhere in this
Agreement.

     2.23  Notwithstanding any other provision of this Agreement, (a) if the
introduction of or any change in any law or regulation (or change in the
interpretation thereof) applicable to Bank or any foreign branch, agent or
correspondent thereof shall make it unlawful, or (b) if any central bank or
other governmental authority having jurisdiction over Bank or any such branch,
agent or correspondent, shall assert that it is unlawful, for Bank to perform
its obligations hereunder or for any such branch, agent or correspondent to act
on behalf of Bank to make Libor Loans to the Borrower or to continue to fund or
maintain Libor Loans to the Borrower hereunder, or (c) if Bank determines after
making all reasonable efforts, that deposits of the relevant amount and for the
relevant Advances to the Borrower are not available to Bank in the Interbank
Market, then, on notice thereof by Bank to the Borrower, the obligation of the
Bank to the Borrower to make future Libor Loans shall terminate.  If, as a
result of any of the foregoing described events, Bank is prohibited from
maintaining Libor Loans, the Bank shall, upon the happening of such event,
notify the Borrower and the Borrower shall, in the case of each Libor Loan, on
the Maturity Date of such Libor Loan (or, in any event, if the Bank so requests,
on such earlier date as may be required by the relevant law, regulation or
interpretation), either prepay such Libor Loan or convert such Libor Loan into a
Prime Rate Loan.

     2.24  If, due to payments made by the Borrower pursuant to this Agreement
or due to the acceleration of the maturity of the Loans pursuant to Article X
hereof or due to any other reason, including, without limitation, by reason of a
payment made pursuant to Section 2.20 of this Agreement, Bank receives payments
of principal of any Libor Loan prior to the Maturity Date for such Advance, the
Borrower shall, upon demand by Bank, pay to Bank any amounts reasonably required
to compensate Bank for any additional losses, costs or expenses which it may
reasonably incur as a result of such payment, including, without limitation, any
loss, costs or expenses reasonably incurred by reason of the liquidation of
reemployment of deposits or other funds acquired by Bank to fund or maintain
such Advances.

     2.25  Whenever any payment of interest, charges or fees to be made
hereunder shall be stated to be due on a day other than a Banking Day, such
payment shall be made on the next succeeding Banking Day (except as provided in
the definition of Maturity Date) and such next succeeding Banking Day shall be
utilized in the computation of the payment of such interest, charges and other
fees.

     2.26  Borrower shall pay to Bank on demand any and all reasonable counsel
fees and other reasonable expenses incurred by Bank in connection with the
preparation, enforcement or amendment of this Agreement, or of any documents
relating thereto, and any and all expenses, including, but not limited to, all
reasonable attorneys' fees and expenses, and all other expenses of like or
unlike nature which may be expended by Bank to obtain or enforce payment or in
the prosecution or defense of any action or concerning any matter growing out of
or connected with the subject matter of this Agreement, or the Obligations or
any of Bank's rights or interests therein or thereto, including, without
limiting the generality of the foregoing, any reasonable counsel fees or
expenses incurred in any bankruptcy or insolvency proceedings of Borrower.

     3.04  The Term Loan shall be subject to a prepayment premium as described
in the Term Note.

     3.05  In consideration of the Bank establishing the Term Loan, the Borrower
shall pay a facility fee equal to one-half of one (.50%) percent of the original
principal balance of the Term Note at the time of execution thereof.

     3.06  The Borrower hereby directs the Bank to debit its demand deposit
account(s) with the Bank in satisfaction of any payments required with respect
to the Term Loan.

     4.01  Subject to and upon the conditions of this Agreement, during the
Availability Period, at the request of the Borrower, the Bank may make Advances
to the Borrower in an aggregate amount not to exceed the Commitment Amount.

     4.02  All Advances under the Acquisition Line shall bear interest, at the
Borrower's option, at either a variable rate of the Bank's Prime Rate or at a

     5.01  Bank enters into this Agreement in reliance upon the warranties and
representations of the Borrower set forth in this Article, each of which is
acknowledged by each entity constituting a Borrower to be material.  Each such
warranty and representation shall be deemed to have been newly made on each

received from the Borrower notice of a change with respect thereto, which change
is not a breach of this Agreement.

     5.02  Borrower has no places of business other than that shown at the

remain in corporate good standing as a corporation in that state, and is duly
qualified as a foreign corporation and is in corporate good standing in each
jurisdiction in which the failure to so qualify would have a material adverse
effect on the condition (financial or otherwise), business, operations,
properties or prospects of the Borrower, and shall hereafter remain duly

qualify would have a material adverse effect on the condition (financial or
otherwise), business, operations, properties or prospects of the Borrower.

     5.05  Borrower's exact legal name is as set forth in this Agreement and

     6.02  Borrower agrees to keep all of its insurable assets insured with
coverage and in amounts not less than that usually carried by one engaged in a

in the prosecution or defense of any action or proceeding concerning any matter

shall constitute a Default under this Agreement.  The entire Obligation of
Borrower to Bank shall become due and payable when payments become due and
payable hereunder upon termination of this Agreement.  Similarly, any default by

                 CONSENT TO JURISDICTION AND JURY TRIAL WAIVER
                 ---------------------------------------------

     12.01 BORROWER AND BANK EACH HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVES ANY RIGHT IT MAY HAVE OR HEREAFTER HAVE TO A TRIAL BY JURY
IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT.  Borrower hereby certifies that neither Bank nor any of its
representatives, agents or counsel has represented, expressly or otherwise, that
Bank would not, in the event of any such suit, action or proceeding, seek to
enforce this waiver of right to trial by jury.  Borrower acknowledges that Bank
has been induced to enter into this Agreement by, among other things, this
waiver.  Borrower acknowledges that Borrower has read the provisions of this
Agreement and in particular, this Section 12.01; has consulted legal counsel;
understands the right Borrower is granting in this Agreement and is waiving in
this Section 12.01 in particular; and makes the above waiver knowingly,
voluntarily and intentionally.

     12.02 Borrower and Bank agree that any action or proceeding to enforce or
arising out of this Agreement may be commenced in any court of the Commonwealth
of Massachusetts sitting in the county of Suffolk, or in the United States
District Court for the District of Massachusetts.



                                  ARTICLE XIII

                                 MISCELLANEOUS
                                 -------------

     13.01 The Borrower will, from time to time, execute and deliver to Bank all
such other and further instruments and documents and take or cause to be taken
all such other and further action as Bank may reasonably request in order to
effect in Bank all rights contemplated in this Agreement.

     13.02 The Borrower may take any action herein prohibited or omit to perform
any act required to be performed by the Borrower upon obtaining Bank's prior
written consent to each such action, or omission to act.  No waiver on Bank's
part on any one occasion shall be deemed a waiver on any other occasion.  Bank
shall not be deemed to have waived any of its rights hereunder unless such
waiver shall be in writing and duly signed by an authorized officer of Bank,
which shall include any vice president or more senior officer of Bank.

     13.03 This Agreement may be amended only by an instrument in writing and
duly signed by the Borrower and an authorized officer of Bank which shall
include any vice president or more senior officer of Borrower.

     13.04 All covenants, agreements, representations and warranties contained
in this Agreement shall bind the Borrower, its successors and assigns, and shall
inure to Bank's benefit and the benefit of Bank's successors and assigns,
whether expressed or not.

     13.05 All rights of Bank hereunder shall be cumulative.  Bank shall not be
required to have recourse to any property of the Borrower before enforcing its
rights or remedies against the Borrower.  The Borrower hereby waives presentment
and protest of any instrument and any notice thereof.

     13.06 If any provision of this Agreement or any other Financing Agreement
shall be held to be illegal or unenforceable, such illegality or
unenforceability shall relate solely to such provision and shall not affect the
remainder of this Agreement.

     13.07 This Agreement shall be construed and enforced in accordance with the
laws of the Commonwealth of Massachusetts.

     13.08 This Agreement shall take effect as an instrument under seal.

     13.09 The captions herein contained are inserted as a matter of convenience
only and such captions do not form a part of this Agreement and shall not be
utilized in the construction hereof.

     13.10 In the event that the Borrower fails to make any payment or take any
action required by this Agreement, Bank may, but shall not be required to, make
such payment or take, or cause to be taken, such action.  If Bank chooses to
make any such payment or to take or cause to be taken any such action, the
amount of such payment and the cost of such action shall become one of the
Obligations, shall be payable upon demand and, until paid in full, shall bear
interest at the rate established pursuant to the terms of this Agreement.

     13.11 Calculation of Adjusted Libor, as well as all other fees and charges
payable with respect to each Libor Loan shall be made and paid as though Bank
had actually funded the relevant Libor Loan through the purchase of a Eurodollar
deposit at Libor in an amount equal to the amount of the Libor Loan and having a
maturity comparable to the relevant Interest Period and through the transfer of
such Eurodollar deposit from an offshore agent or office of Bank to a domestic
office of Bank in the United States of America, provided, however, that Bank may
fund each Libor Loan in any manner it sees fit in accordance with applicable law
and the foregoing assumptions shall be nevertheless used for the calculation of
the Libor Rate and such other fees and charges.

     13.12  All Obligations hereunder shall be the joint and several Obligations
of each Borrower hereunder and Bank may look to any Borrower for the
satisfaction of any such Obligations.  This relationship is more particularly
described in the Agented Borrowing Agreement among the Agent Borrower, each
Borrower and the Bank of even date, which Agented Borrowing Agreement is
incorporated herein as if set forth in full herein.

     13.13 Bank may at any time pledge all or any portion of its rights under
the Financing Agreements including any portion of the promissory notes to any of
the twelve (12) Federal Reserve Banks organized under Section 4 of the Federal
Reserve Act, 12 U.S.C. Section 341.  No such pledge or enforcement thereof shall
release Bank from its obligations under any of the Financing Agreements.

                                       26

     13.14 Bank shall have the unrestricted right in the event of additional
financing arrangements with Borrower not in contemplation at the time of the
execution of this Agreement  at any future time and from time to time, and
without the consent of Borrower, but with written notice to Borrower to grant to
one or more banks or other financial institutions (each a "Participant")
participating interests in Bank's obligation to lend hereunder and/or any or all
of the Loans held by Bank hereunder.  In the event of any such grant by Bank of
a participating interest to a Participant, Bank shall remain responsible for the
performance of its obligations hereunder and Borrower shall continue to deal
solely and directly with Bank in connection with Bank's rights and obligations
hereunder.  Bank may furnish any information concerning Borrower in its
possession from time to time to prospective Participants, provided that Bank
shall require any such prospective Participant to agree in writing to maintain
the confidentiality of such information.

     13.15 Upon receipt of an affidavit of an officer of Bank as to the loss,
theft, destruction or mutilation of the Revolving Line Note, Term Note or any
Acquisition Term Notes or any other security document which is not of public
record, and, in the case of any such loss, theft, destruction or mutilation,
upon surrender and cancellation of such note or other security document,
Borrower will issue, in lieu thereof, a replacement note or other security
document in the same principal amount thereof and otherwise of like tenor.

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

     14.01   The Loans by the Bank hereunder are secured pursuant to the
respective Security Agreements (All Assets) of each Borrower hereunder.  The
Bank may look to all Collateral for the satisfaction of the Borrowers'
Obligations to the Bank under this Agreement and under the Financing Agreements
without any requirement to marshall any assets.  Upon termination of the
Revolving Loan, other than from internally generated funds, all Obligations of
the Borrower to the Bank shall be due and payable in full.


     IN WITNESS WHEREOF, the parties hereto have cause this Agreement to be
executed as an instrument under seal as of the day and year first above written.

                               SECURED TERM NOTE



$7,000,000.00                                                 April 15, 1999
                                                       Boston, Massachusetts


     For value received, the undersigned jointly and severally promise to pay to
Fleet National Bank ("Bank"), or order, at its office at One Federal Street,
Boston, Massachusetts 02110, or at such other place as may be designated in
writing by the holder hereof, the principal sum of Seven Million ($7,000,000.00)
Dollars in eighty-four (84) consecutive monthly installments, as follows:
$83,333.00 on November 1, 1999 and the same amount (except the last installment,
which shall be in the amount of the remaining outstanding principal balance) on
the 1st day of each month thereafter until this note is paid in full.  Interest
shall be charged on the said principal sum outstanding at a rate equal to the
Adjusted Libor plus two and three-quarters percent (2.75%) as defined in the
undersigneds' Loan Agreement with the Bank of even date (the "Loan Agreement"),
adjusted every month as provided below.  Interest on the aggregate principal
balance owing to the Bank at the close of each day shall be payable monthly in
arrears commencing on the 1st day of the month next succeeding the date hereof,
and continuing on the 1st day of each month thereafter until such principal
balance is fully and finally paid.  Notwithstanding the foregoing interest
provisions, the undersigned shall have the benefit of, and be subject to the
terms of, that certain ISDA Master Swap Agreement between the undersigned and
the Bank dated April 15, 1999 (the "Swap Agreement").


     The Adjusted Libor shall be calculated on the date hereof, and recalculated
on the numerically corresponding day of each month thereafter, provided that if
such day is not a Banking Day, then the Adjusted Libor shall be recalculated on
the next preceding or the next succeeding day which is a Banking Day as
determined in good faith by the Bank in accordance with the then current bank
practices in the relevant Interbank Market (such date hereinafter referred to as
an "Adjustment Date").  Interest shall be computed on the basis of the actual
number of days elapsed over a year of 360 days.  Each Adjusted Libor interest
rate calculated hereunder on an Adjustment Date shall become the applicable
interest rate until the next Adjustment Date.


     If this note is not paid in full on the date of maturity or upon the
exercise by the holder of its rights in the event of the undersigned's default,
interest on unpaid balances shall thereafter be payable at an interest rate per
annum equal to five (5%) percent greater than the rate of interest specified
herein.

     If the entire amount of any required principal and/or interest is not paid
in full within ten (10) days after the same is due, the undersigned shall pay to
the Bank a late fee equal to five (5%) percent of the required payment.  In no
event, however, shall the outstanding principal advances evidenced by this note
bear interest rate in excess of the maximum interest permitted by applicable
law.

     In the event of prepayment of this note, whether by acceleration or
otherwise, the undersigned shall pay to Bank any amounts required to compensate
Bank for any additional
<PAGE>
 
losses, costs or expenses which it may reasonably incur as a result of such
payment, including, without limitation, any loss, costs or expenses incurred by
reason of the liquidation or redeployment of deposits or other funds acquired by
Bank to fund or maintain the loan evidenced by this note. The provisions of this
paragraph, however, shall be subject in all respects to the provisions of the
Swap Agreement.

     At the option of the holder, this note shall become immediately due and
payable without notice or demand upon the occurrence at any time of (i) the
failure to pay in full and when due any installment of principal or interest
hereunder; or (ii) one or more Events of Default as defined in the Loan
Agreement and the expiration of any applicable grace period.


     Any and all deposits or other sums at any time or times credited by or due
from the holder to, and all securities or other property in possession of the
holder for safekeeping or otherwise and belonging to, any maker, indorser, or
guarantor of this note are and shall be subject to a security interest in favor
of the holder to secure payment of this note and the payment and performance of
any and all other liabilities and obligations, direct or indirect, absolute or
contingent, due or to become due or that may hereafter be contracted, of said
respective maker, indorser, or guarantor to the holder.  Upon any of the events
specified above or upon non-payment of this note or any of such liability or
obligation whenever due, and at any time or times thereafter, without any demand
or notice, except to such extent as notice may be required by applicable law,
the holder may sell or dispose of any or all such securities or other property
and may exercise any and all the rights accorded the holder by the Massachusetts
Uniform Commercial Code. The holder may apply or set off such deposits or other
sums at any time whether or not the liability of the maker, indorser or
guarantor is then due.  The provisions of this paragraph are cumulative to, and
not exclusive of, any other rights that the holder has with respect to such
deposits, sums, securities or other property under other agreements or
applicable principles of law.  The holder shall have no duty to take steps to
preserve rights against prior parties as to such securities or other property.


     Every maker, indorser, and guarantor of this note, or the obligation
represented by this note, waives presentment, demand, notice, protest, and all
other demands or notices in connection with the delivery, acceptance,
indorsement, performance, default, or enforcement of this note, assents to any
and all extensions or postponements of the time of payment or any other
indulgence, to any substitution, exchange, or release of collateral, and/or to
the addition or release of any other party or person primarily or secondarily
liable, and generally waives all suretyship defenses and defenses in the nature
thereof.


     The undersigned will pay all costs and expenses of collection, including
attorneys' fees, incurred or paid by the holder in enforcing this note or the
obligations hereby evidenced, to the extent permitted by law.


     No delay or omission of the holder in exercising any right or remedy
hereunder shall constitute a waiver of any such right or remedy.  Acceptance by
the holder of any payment after acceleration shall not be deemed a waiver of
such acceleration.  A waiver on one occasion shall

                                       2
<PAGE>
 
not operate as a bar to or waiver of any such right or remedy on any future
occasion.

     The holder need not enter payments of principal or interest upon this note
but may maintain a record thereof on a separate ledger maintained by the holder.



     The word "holder" as used in this note shall mean the payee or indorsee of
this note who is in possession of it or the bearer if this note is at the time
payable to bearer.



     THE UNDERSIGNED AND THE BANK HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY THAT THE UNDERSIGNED OR THE BANK
MAY HAVE IN ANY ACTION OR PROCEEDING, IN LAW OR IN EQUITY, IN CONNECTION WITH
THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS RELATED THERETO.  THE UNDERSIGNED
HEREBY CERTIFIES THAT NO REPRESENTATIVE OR AGENT OF THE BANK HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT THE BANK WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL PROVISION.  THE UNDERSIGNED
ACKNOWLEDGES THAT THE BANK HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE PROVISIONS OF THIS SECTION.

     All capitalized terms used herein and not otherwise defined shall have the
meanings set forth in the Loan Agreement.  This Note is issued pursuant to the
Loan Agreement, which more explicitly describes the rights and obligations of
the undersigned and the Bank.


     All rights and obligations hereunder shall be governed by the law of the
Commonwealth of Massachusetts and this note shall be deemed to be under seal.

     On May 31, 2001, for value received, the undersigned, jointly and severally
promise to pay to the order of Fleet National Bank (the "Bank") at the office of
Bank at One Federal Street, Boston, Massachusetts 02110, or such other place as
the Bank shall designate, Three Million ($3,000,000.00) Dollars, or such lesser
principal amount advanced to the undersigned by the Bank under the revolving
line of credit established pursuant to a Loan Agreement of even date (the
"Agreement"), which remains outstanding, together with interest thereon as
follows:   (i)  on outstanding principal designated as a Prime Rate Loan
pursuant to Section 2.05 of the Agreement, interest shall accrue from the date
thereof, payable monthly in arrears on the first day of each calendar month
prior to the due date thereof, and upon the due date thereof, at a fluctuating
interest rate per annum equal to the Bank's Prime Rate in effect from time to
time.  Each change in such interest rate shall take effect simultaneously with
the corresponding change in such Prime Rate.  "Prime Rate" shall mean the rate
of interest announced by the Bank in Boston, Massachusetts, from time to time as
its Prime Rate, it being understood that such rate is a reference rate and not
necessarily the lowest rate of interest charged by Bank, (ii) on outstanding
principal designated as a Libor Loan pursuant to Section 2.05 of the Agreement,
interest shall accrue from the Borrowing Date for such Advance through and
including the Maturity Date chosen by the undersigned with respect to such
Advance, at a fixed interest rate per annum equal to the aggregate of the
Adjusted Libor plus Margin, and shall be payable on the sooner of the first day
of each month or the Maturity Date.  All capitalized terms not otherwise defined
herein shall have the meanings set forth in the Agreement.

     This note shall, at the option of the Bank, become immediately due and
payable without notice or demand upon the occurrence of any Event of Default
under the Agreement, subject to any applicable grace periods set forth therein.

     If this note is not paid in full on the date of maturity or upon the
exercise by the holder of its rights in the event of the undersigned default,
interest on unpaid balances shall thereafter be payable at an interest rate per
annum equal to four (4%) percent greater than the rate of interest specified
herein.

     Any and all deposits or other sums at any time or times credited by or due
from the holder to, and all securities or other property in possession of the
holder for safekeeping or otherwise and belonging to, any maker, indorser, or
guarantor of this note are and shall be subject to a security interest in favor
of the holder to secure payment of this note and the payment and performance of
any and all other liabilities and obligations, direct or indirect, absolute or
contingent, due or to become due or that may hereafter be contracted, of said
respective maker, indorser, or guarantor to the holder.  Upon any of the events
specified above or upon 
<PAGE>
 
non-payment of this note or any of such liability or obligation whenever due,
and at any time or times thereafter, without any demand or notice, except to
such extent as notice may be required by applicable law, the holder may sell or

$__________                                            ________, 1999/200__
                                                       Boston, Massachusetts

     For value received, the undersigned jointly and severally promise to pay to
Fleet National Bank ("Bank"), or order, at its office at One Federal Street,
Boston, Massachusetts 02110, or at such other place as may be designated in
writing by the holder hereof, the principal sum of [the principal amount of the
Advance under the Acquisition Line) ($_____________) Dollars in eighty-four (84)
consecutive monthly installments, as follows: [1/84th of the amount of the
Advance] on [The 1st day of the 6th month following the date of the Advance] and
the same amount (except the last installment, which shall be in the amount of
the remaining outstanding principal balance) on the 1st day of each month
thereafter until this note is paid in full.  Interest shall be charged on the
said principal sum outstanding at a rate equal to the Adjusted Libor plus two
and three-quarters percent (2.75%) prior to the undersigned achieving
Profitability and Adjusted Libor plus two and one-quarter (2.25%) percent
thereafter as those terms are defined in the undersigneds' Loan Agreement with
the Bank of even date (the "Loan Agreement"), adjusted every month as provided
below.  Interest on the aggregate principal balance owing to the Bank at the
close of each day shall be payable monthly in arrears commencing on the 1st day
of the month next succeeding the date hereof, and continuing on the 1st day of
each month thereafter until such principal balance is fully and finally paid.
Notwithstanding the foregoing interest provisions, the undersigned shall have
the benefit of, and be subject to the terms of, that certain ISDA Master Swap
Agreement between the undersigned and the Bank dated April ___, 1999 (the "Swap
Agreement").

     The Adjusted Libor shall be calculated on the date hereof, and recalculated
on the numerically corresponding day of each month thereafter, provided that if
such day is not a Banking Day, then the Adjusted Libor shall be recalculated on
the next preceding or the next succeeding day which is a Banking Day as
determined in good faith by the Bank in accordance with the then current bank
practices in the Interbank Market (such date hereinafter referred to as an
"Adjustment Date").  Interest shall be computed on the basis of the actual
number of days elapsed over a year of 360 days.  Each Adjusted Libor interest
rate calculated hereunder on an Adjustment Date shall become the applicable
interest rate until the next Adjustment Date.

     If this note is not paid in full on the date of maturity or upon the
exercise by the holder of its rights in the event of the undersigned's default,
interest on unpaid balances shall thereafter be payable at an interest rate per
annum equal to four (4%) percent greater than the rate of interest specified
herein.

     If the entire amount of any required principal and/or interest is not paid
in full within ten (10) days after the same is due, the undersigned shall pay to
the Bank a late fee equal to four (4%) percent of the required payment.  In no
event, however, shall the outstanding principal advances evidenced by this note
bear interest rate in excess of the maximum interest permitted by applicable
law.
<PAGE>
 
     In the event of prepayment of this note, whether by acceleration or
otherwise, the undersigned shall pay to Bank any amounts required to compensate
Bank for any additional losses, costs or expenses which it may reasonably incur
as a result of such payment, including, without limitation, any loss, costs or
expenses incurred by reason of the liquidation or redeployment of deposits or
other funds acquired by Bank to fund or maintain the loan evidenced by this
note.  The provisions of this paragraph, however, shall be subject in all
respects to the provisions of the Swap Agreement.

     At the option of the holder, this note shall become immediately due and
payable without notice or demand upon the occurrence at any time of one or more
Events of Default as defined in the Loan Agreement and the expiration of any
applicable grace period.

     Any and all deposits or other sums at any time or times credited by or due
from the holder to, and all securities or other property in possession of the
holder for safekeeping or otherwise and belonging to, any maker, indorser, or
guarantor of this note are and shall be subject to a security interest in favor
of the holder to secure payment of this note and the payment and performance of
any and all other liabilities and obligations, direct or indirect, absolute or
contingent, due or to become due or that may hereafter be contracted, of said
respective maker, indorser, or guarantor to the holder.  Upon any of the events
specified above or upon non-payment of this note or any of such liability or
obligation whenever due, and at any time or times thereafter, without any demand
or notice, except to such extent as notice may be required by applicable law,
the holder may sell or dispose of any or all such securities or other property
and may exercise any and all the rights accorded the holder by the Massachusetts
Uniform Commercial Code.  Upon the occurrence of an Event of Default under the
Loan Agreement the holder may apply or set off such deposits or other sums at
any time whether or not the liability of the maker, indorser or guarantor is
then due.  The provisions of this paragraph are cumulative to, and not exclusive
of, any other rights that the holder has with respect to such deposits, sums,
securities or other property under other agreements or applicable principles of
law.  The holder shall have no duty to take steps to preserve rights against
prior parties as to such securities or other property.

     Every maker, indorser, and guarantor of this note, or the obligation
represented by this note, waives presentment, demand, notice, protest, and all
other demands or notices in connection with the delivery, acceptance,
indorsement, performance, default, or enforcement of this note, assents to any
and all extensions or postponements of the time of payment or any other
indulgence, to any substitution, exchange, or release of collateral, and/or to
the addition or release of any other party or person primarily or secondarily
liable, and generally waives all suretyship defenses and defenses in the nature
thereof.

     The undersigned will pay all reasonable costs and expenses of collection,
including reasonable attorneys' fees, incurred or paid by the holder in
enforcing this note or the obligations hereby evidenced, to the extent permitted
by law.

hereunder shall constitute a waiver of any such right or remedy.  Acceptance by
the holder of any payment after acceleration shall not be deemed a waiver of

waiver of any such right or remedy on any future occasion.

     THE UNDERSIGNED AND THE BANK HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY THAT THE UNDERSIGNED OR THE BANK
MAY HAVE IN ANY ACTION OR PROCEEDING, IN LAW OR IN EQUITY, IN CONNECTION WITH

                              SECURITY AGREEMENT
                                  (All Assets)
                                        
     Sight Resource Corporation, a Delaware corporation with a principal place

1.02   ALL ACCOUNTS AND ACCOUNTS RECEIVABLE of the Borrower now existing or
       hereafter arising; meaning all accounts, accounts receivable, papers,
       notes, drafts, acceptances, and all other debts, obligations, and
       liabilities in whatever form owing to the Borrower from any person, firm,

1.03   ALL DOCUMENTS of the Borrower now existing or hereafter arising; meaning
       all documents of title, including bills of lading, dock warrants, dock
       receipts, warehouse receipts, and orders for the delivery of goods, and
       also any other document which in the regular course of business or
       financing is treated as adequately evidencing that the person in the
       possession of it is entitled to receive, hold, and dispose of the
       document and goods it covers.

1.04   ALL INSTRUMENTS of the Borrower now existing or hereafter arising;
       meaning all negotiable instruments, securities, and any other writings
       which evidence a right to payment of money and are not themselves
       security agreements or leases and are of a type which are in the ordinary
       course of business transferred by delivery with any necessary endorsement
       or assignment.

1.05   ALL CHATTEL PAPER of the Borrower now existing or hereafter arising;

       instruments, including, but not limited to, general intangibles of the
       following description or type: goodwill, literary rights, contract rights

1.07   ALL INVESTMENT PROPERTY of the Borrower, where located, now or hereafter
       existing or hereafter acquired including all securities (whether
       certificated or not), security entitlements, security accounts, financial
       assets and related rights, together with all proceeds of any of the
       foregoing.

1.08   ALL OTHER GOODS of the Borrower, wherever located, now existing or
       hereafter acquired; meaning all motor vehicles, equipment, machinery, and
       other tangible personal property, whether fixtures or not, any and all
       records relating to any of the Collateral (as defined below) and all

     It is the Borrower's express intention that the continuing grant of this
security interest remain as security for payment and performance of all of its

not contemplated by the parties at the time of the granting of this security
interest.  The notice of the continuing grant of this security interest
therefore shall not be required to be stated on the face of any document

being secured hereby.  If any Liability of the Borrower shall be or become
excused, the Borrower hereby expressly hypothecates his, her, its, or their
ownership interest in the Collateral to the extent required to satisfy such
Liabilities, without restriction or limitation.  Any such Liabilities will
include all advances by the Bank whether or not the advances are made pursuant
to commitments.

       kind and description, including those arising under a Loan Agreement with
       the Bank of even date (the "Loan Agreement"), direct or indirect,
       absolute or contingent, due or to become due, now existing or hereafter
       arising, regardless of how they arise or by what agreement or instrument
       they may be evidenced, including those arising under this Agreement, or
       whether evidenced by any agreement or instrument, including obligations
       to perform acts and refrain from taking action as well as obligations to
       pay money.

       property and other goods, as those terms are defined in Section 1 hereof.

       security interests, mortgages, liens, and encumbrances, except those
       granted or allowed under this Agreement and those set forth on the
       attached Schedule A, and the Borrower has marketable title to all
       Collateral and shall defend the same against the claims and demands of
       all persons.  The Bank has the right but not the duty to discharge any
       liability giving rise to a lien on Collateral, including any liens of any
       taxing authority, and the Borrower shall repay the Bank immediately for
       all amounts paid by the Bank to discharge such liabilities.

3.03   LOCATION OF COLLATERAL: Tangible Collateral, including, but not limited
       to, equipment, inventory, and fixtures, and if the Bank permits the
       Borrower to retain possession thereof, instruments, documents, and
       chattel paper, will be kept in the possession of the Borrower at its
       place of business named above, or those set forth on the attached
       Schedule A.  The location or locations of such Collateral shall not be
       changed without providing written notice thereof to the Bank.
       Immediately upon the Bank's request, whether or not the Borrower is in
       default with respect to any Liability to the Bank, the Borrower will turn
       over to the Bank all instruments, documents and chattel paper which are
       Collateral under this Agreement.

3.04   RECORDS AND INFORMATION WITH RESPECT TO BORROWER AND COLLATERAL:

       (a)  The Borrower will furnish all information, financial or otherwise,
            that a duly authorized lending officer of the Bank deems reasonably
            necessary to properly inform the Bank with respect to Collateral or
            the condition of the Borrower.  The Borrower will inform the Bank
            immediately in the event of any material change in the Borrower's
            financial condition or in the event of any material breach of this
            Agreement or in the event that any of the representations and
            warranties herein contained do not continue to be true and correct
            in any material respect as though continuously made to the Bank.

                                       3
<PAGE>
 
       (b)  The Borrower will execute upon the request of the Bank such
            financing statements and like papers as the Bank deems reasonably
            necessary to properly protect Collateral and its security interest
            therein and will pay the cost of filing them in such offices as the
            Bank requests.

3.05   FIXTURES: If any machinery, equipment, or other property serving as
       Collateral under this Agreement is or will be attached to any real
       estate, the Borrower will, upon Bank's request, furnish the Bank with a
       description of such real estate with a disclaimer, signed by all persons
       having an interest in said real estate, of any interest in the Collateral
       which has or may have priority over the Bank's interest, and will notify
       the Bank in writing of any intended sale, mortgage, or conveyance of such
       real estate, and will give written notice of the terms and conditions of
       this Agreement to any prospective purchaser, mortgagee, or grantee of
       such real estate.

3.06   LIABILITIES OWING TO BORROWER:  Any liabilities in whatever form owing to
       the Borrower from any person, firm, or other legal entity serving as
       Collateral are and will be good and valid indebtedness not subject to any
       defenses, set-offs, claims, counter-claims, or agreements under which any
       deduction or discount may be made thereon, except as specified to the
       Bank on a statement or invoice made available to the Bank on or prior to
       the date hereof or from time to time hereafter.

3.07   RETURNED MERCHANDISE: The Bank may in its unfettered discretion charge to
       the Borrower the amount represented to be owing on any liability, in
       whatever form owing to the Borrower, from whatever source, if said
       liability serves as Collateral under this Agreement, and if any
       merchandise giving rise to any such liability is returned, and until such
       debit is made, Borrower shall hold any such returned merchandise
       segregated in trust for the Bank subject to its exclusive disposition.

3.08   TAXES:  The Borrower will pay any sales or other taxes which may become
       due and payable with respect to a sale or other transaction giving rise
       to any Collateral, unless such tax is being contested in good faith by
       appropriate proceedings with appropriate reserves established.

3.09   CHATTEL PAPER: The Borrower agrees to label all chattel paper serving as
       Collateral under this Agreement with the words, "Subject to the security
       interest of (the Bank)", naming the Bank.

3.10   INSURANCE:

       (a)  The Borrower agrees at its own expense to keep all Collateral
            insured in accordance with the requirements of the Loan Agreement.

       (b)  The Bank shall have no risk, liability, or responsibility in
            connection with payment or non-payment of any loss, the sole
            obligation of the Bank being to 

                                       4
<PAGE>
 
            credit the Borrower's loan account with the net proceeds of any
            insurance payments received on account of any loss.

3.11   SALE OF COLLATERAL: Unless otherwise specifically provided by this
       Agreement or the Loan Agreement, the Borrower will not sell any
       Collateral without the prior written consent of the Bank.
       Notwithstanding, provided the Borrower is not in default hereunder the
       Borrower shall have the right to sell inventory, which may be Collateral,
       in the ordinary course of its business.  A sale in the ordinary course of
       business shall not include a transfer in total or partial satisfaction of
       a debt, other than a debt which has arisen solely as a result of
       prepayment or deposit by customers of the Borrower for items of inventory
       subsequently to be purchased or delivered.  Borrower shall also be
       entitled to sell (or trade in) obsolete equipment or inventory so long as
       Borrower receives therefor a sum (or credit) substantially equal to such
       equipment's or inventory's fair value.

3.12   BANK'S RIGHT TO POSSESSION:

       (a)  Unless otherwise provided by law, at any time after the occurrence
            of an Event of Default hereunder, the Bank shall have the right to
            the immediate possession of all Collateral and its products and
            proceeds, and in its sole discretion may operate and use said
            Collateral, complete work in process, and sell Collateral without
            being liable to the Borrower on account of any losses, damage, or
            depreciation that may occur as a result thereof so long as the Bank
            shall act in good faith, in a commercially reasonable manner.

       (b)  Unless otherwise provided by law, at any time after the occurrence
            of an Event of Default hereunder, the Bank may, at the expense of
            the Borrower, maintain possession of the Borrower's premises by the
            use of a custodian or custodians, or in such other manner as the
            Bank may determine.

       (c)  Unless otherwise provided by law, at any time after the occurrence
            of an Event of Default hereunder, the Bank may at all times, at the
            expense of the Borrower, enter upon any premises on which Collateral
            may be situated and remove any such Collateral to such other places
            as the Bank determines.

       (d)  Unless otherwise provided by law, the Bank may at any time, after
            the occurrence of an Event of Default hereunder, transfer any
            Collateral into its own name or that of its nominee and may at any
            time after demand or the occurrence of an Event of Default hereunder
            receive the income thereon and hold the same as security for
            Liabilities or apply it to principal or interest due on the
            Liabilities.

SECTION 4.  COLLECTION:

4.01   (a)  The Bank may at any time and from time to time after the occurrence
            of an Event of Default hereunder require the Borrower to establish a
            "lock box" arrangement with the Bank for the receipt of Account
            Debtor remittances.

       (b)  The Bank may at any time after the occurrence of an Event of Default
            hereunder, notify Account Debtors, on any Collateral, or require the
            Borrower to notify such Account Debtors, that they shall make all
            payments on their account or accounts with the Borrower directly to
            the Bank; or require the Borrower to hold all proceeds received from
            collection in trust for the Bank without commingling the same with
            other funds of the Borrower, and to turn the same over to the Bank
            immediately upon receipt the identical form received, at which time
            the Bank may at its option either apply such proceeds to the
            Liabilities of the Borrower, in accordance with Section 4.03, or
            release such proceeds to the Borrower for use in its business.

       (c)  The Bank has the right at any time after the occurrence of an Event
            of Default hereunder, directly or through its agent, to collect
            proceeds directly from Account Debtors, on any Collateral and for
            that purpose to do all acts and things necessary or incident
            thereto, including the right to sue on such accounts, and to sell,
            transfer, set over, compromise, discharge, or extend the whole or
            any part of the accounts.

                                       6
<PAGE>
 
       (d)  Borrower does hereby make, constitute and appoint any officer or
            agent of Bank as Borrower's true and lawful attorney-in-fact, with
            power to endorse the name of Borrower or any of Borrower's officers
            or agents upon any notices, checks, drafts, money orders, or other
            instruments of payment (including payments payable under any policy
            of insurance on the Collateral) or Collateral that may come into
            possession of the Bank in full or part payment of any amounts owing
            to Bank; to sign and endorse the name of Borrower or any of
            Borrower's officers or agents upon any warehouse receipts, drafts
            against debtors, assignments, verifications and notices in
            connection with accounts, and any instruments or documents relating
            thereto, or to Borrower's rights therein; to give written notice to
            such office or officials of the United States Post Office to effect
            such change or changes of address so that all mail addressed to the
            Borrower may be delivered directly to the Bank; granting unto
            Borrower's said attorney full power to do any and all things
            necessary to be done in and about the premises as fully and
            effectually as Borrower might or could do, and hereby ratifying all
            that said attorney shall lawfully do or cause to be done by virtue
            hereof.  Neither the Bank nor the attorney shall be liable for any
            acts or omissions nor for any errors of judgment or mistake, except
            for their gross negligence or willful misconduct.  This power of
            attorney shall be irrevocable for the term of this Agreement and all
            transactions hereunder and thereafter as long as Borrower may be
            indebted to Bank.  With the exception of the power granted to the
            Bank to endorse checks, drafts, and any other form of payment, which
            right may be exercised at any time and from time to time, the Bank
            will not exercise any of the powers granted hereunder absent the
            occurrence of an Event of Default hereunder.

4.02   Until the Bank exercises the rights contained in Section 4.01 following
       an Event of Default hereunder, the Borrower may continue to collect
       proceeds from Account Debtors on any Collateral and use the proceeds in
       any lawful manner not inconsistent with the terms of this Agreement.

4.03   In the event that the Bank exercises the rights contained in Section 4.01
       following an Event of Default hereunder, the Bank shall credit to the
       Borrower the proceeds obtained from Account Debtors of the Borrower, such
       credits to be entered within two (2) business days after receipt of the
       proceeds.  Such credits, however, are conditional upon final payment to
       the Bank at its office in cash or solvent credits of the items giving
       rise to them, and, if any item is not so paid, the amount of any credit
       given with respect to any of the Borrower's Liabilities shall be reversed
       or, in the discretion of the Bank, it shall be charged to any deposit
       accounts of the Borrower with the Bank, whether or not the item is
       returned.

SECTION 5.  DEFAULT AND ACCELERATION:

                                       7
<PAGE>
 
5.01   Any or all of the Liabilities of the Borrower to the Bank shall, at the
       option of the Bank and notwithstanding any time or credit allowed by any
       instrument evidencing a Liability, be immediately due and payable without
       notice or demand upon the occurrence of any of the following events of
       default (each an "Event of Default" hereunder):

       (a)  The occurrence of an Event of Default under the Loan Agreement
            following the expiration of any applicable grace period;

       (b)  An injunction or attachment against property of the Borrower remains
            undischarged for a period of thirty (30) days;

       (c)  The security interest granted to the Bank in the Collateral shall,
            at any time after the execution and delivery of this Agreement, for
            any reason, ceases (i) to create a valid and perfected first
            priority security interest in the Collateral including, without
            limitation, the occurrence of any event which would cause a lien
            creditor, as that term is defined in Section 9-301 of the Code, to
            take priority over advances made by Bank; (ii) this Agreement shall
            cease to be in full force and effect or shall be declared null and
            void, or the validity or enforceability hereof shall be contested by
            the Borrower; or (iii) any guarantor of the Liabilities denies it
            has any further liability or obligation with respect to such
            Liabilities or terminates its guaranty or fails to honor any of its
            Liabilities under such guaranty.

5.02   Upon the occurrence of any Events of Default set forth in Section 5.01,
       the Bank shall have all the rights and remedies of a secured party under

       all other rights and remedies mentioned in this Agreement.  Unless
       otherwise provided by law, the Bank may require the Borrower to assemble
       any tangible personal property constituting Collateral and make it
       available to the Bank at a place to be designated by the Bank which is
       reasonably convenient to both parties.

5.03   The Borrower hereby grants to the Bank a nonexclusive irrevocable license
       in connection with the Bank's exercise of its rights hereunder, to use,
       apply and affix any trademark, trade name, logo or the like in which the
       Borrower now or hereafter has rights, which license may be used solely by
       the Bank upon the occurrence of any Event of Default.

SECTION 6.  EXPENSES:

6.01   The Borrower shall pay or reimburse the Bank on demand for all reasonable
       out-of-pocket expenses which the Bank may incur in connection with this
       Agreement and the preparation thereof, the making of any loan in
       connection herewith, or the collection of the Borrower's Liabilities
       secured under this Agreement, including but not limited to reasonable
       attorney's fees, and reasonable fees and expenses related to the
       perfection and protection of any security interest granted by 

                                       8
<PAGE>

       Borrower's funds on deposit with the Bank.

       hereunder shall be cumulative and not exclusive of any rights or remedies
       which it would otherwise have.

7.03   Any determination that any provision of this Agreement or any application
       thereof is invalid, illegal or unenforceable in any respect in any
       instance shall not affect the validity, legality and enforceability of
       such provision in any other instance, nor the validity, legality or
       enforceability of any other provision of this Agreement.

       shall extend to any subsequent default or any other default.

7.06   No delay on the part of the Bank in exercising any of the rights granted
       or referred to in this Agreement shall be held to constitute a waiver.

SECTION 8.  NOTICE, ASSIGNMENT, TERMINATION:

8.01   Unless otherwise provided for by law, any demand, notice, or other
       communication to the Borrower that the Bank may elect to give shall be
       effective if sent in accordance with the terms of the Loan Agreement.

8.02   If at any time or times by assignment or otherwise the Bank assigns this
       Agreement, such assignment shall carry with it the Bank's powers and
       rights under this Agreement and the transferee shall become vested with
       said powers and rights whether or not they are specifically referred to
       in the transfer.  If and to the extent the Bank retains any other
       Liability or Collateral, the Bank will continue to have the rights and

8.04   Any obligations the Bank may have to the Borrower, whether now existing

                SECURITY AGREEMENT (Pledged Collateral)


      In consideration of loans heretofore, now, or hereafter made to Sight
Resource Corporation  (hereinafter called the "Pledgor") by Fleet National Bank
(hereinafter called the "Bank"), and to secure payment of any liability or
obligation of the Pledgor to the Bank, direct or indirect, primary or secondary,
now existing or hereafter arising (said liabilities and obligations hereby
secured being hereinafter called "Obligations"), the Pledgor assigns, transfers
and delivers to the Bank the collateral described on Exhibit A attached hereto
and made a part hereof, together with any additions to or substitutions for said
property and any and all proceeds of the same, all of which shall hereinafter be
referred to as "Collateral".
 
      Upon an event of default hereunder, or upon default in the payment or
performance of any of the Obligations as set forth and more particularly
described as an "Event of Default" under that certain Loan Agreement between
Bank and Pledgor of even date (the "Loan Agreement"), or upon the occurrence of
any event which would entitle the Bank to accelerate the maturity of any of the
Obligations in each case beyond any applicable grace periods, and at any time or
times thereafter, without any demand or notice, except as may be required by
applicable law, the Bank may sell or otherwise dispose of any or all of the
Collateral and may exercise any and all rights and remedies accorded to it by
Article 9 of the Massachusetts Uniform Commercial Code, as amended from time to
time, or otherwise accorded by law, all as the Bank or any authorized person
acting for it may determine, including, without limitation of the foregoing,
bidding and/or becoming purchaser at any public sale, free from any right of
redemption, which the Pledgor hereby waives and releases, and no purchaser shall
be responsible for the application of the purchase money.  The Pledgor agrees
that five (5) days notice will be deemed reasonable, if any is required.

      The Bank at its option, upon any event of default hereunder or under the
Loan Agreement  may, but shall have no obligation to do so, demand, sue for,
collect, or make any compromise or settlement it deems desirable with reference
to the Collateral, including, without limitation, the exercise of all rights of
a secured party or mortgagee as to any security for any Collateral.  The Bank
shall have no duty as to collection or protection of any Collateral or any
income or distribution thereon nor as to the preservation of any rights,
including, without limitation, rights against prior parties, beyond safekeeping
of the Collateral or as otherwise required by law.

      The Bank may apply any and all proceeds of the Collateral, however
arising, and other amounts collected or received in the exercise of its rights
hereunder to the Obligations, whether or not then due, and may exercise said
rights, without regard to the existence of any other security for any
Obligation.

      The Pledgor hereby waives notice of any and all advances, extensions or
renewals, and of any default hereunder or as to any Obligation except as
provided under the Loan Agreement, as well as presentment, demand, notice, and
protest as to any and all Obligations and also all 
<PAGE>
 
Obligations of the Pledgor hereunder; and the Pledgor agrees that any Collateral
may be exchanged or surrendered from time to time without notice to or further
assent from the Pledgor and without in any manner releasing the Bank's rights in
any other Collateral and the Pledgor hereby waives all suretyship defenses
generally.

      No delay or omission by the Bank in exercising or enforcing any of its
rights, powers, privileges, remedies, immunities or discretions (all of which
are hereinafter collectively referred to as the "Bank's rights and remedies")
hereunder shall constitute a waiver thereof; and no waiver by the Bank of any
default of the Borrower hereunder shall operate as a waiver of any other default
hereunder.  No term or provision hereof shall be waived, altered or modified
except with the prior written consent of the Bank, which consent makes explicit
reference to this Agreement.  Except as provided in the preceding sentence, no
other agreement or transaction, of whatsoever nature, entered into between the
Bank and the Borrower at any time (whether before, during or after the effective
date or term of this Agreement), shall be construed in any particular as a
waiver, modification or limitation of any of the Bank's rights and remedies
under this Agreement (nor shall anything in this Agreement be construed as a
waiver, modification or limitation of any of the Bank's rights and remedies
under any such other agreement or transaction), but all of the Bank's rights and
remedies not only under the provisions of this Agreement but also of any such
other agreement or transaction shall be cumulative and not alternative or
exclusive, and may be exercised by the Bank at such time or times and in such
order of preference as the Bank in its sole discretion may determine.

      If any provision of this Agreement or portion of such provision or the
application thereof to any person or circumstance shall to any extent be held
invalid or unenforceable, the remainder of this Agreement (or the remainder of
such provision) and the application thereof to other persons or circumstances
shall not be affected thereby.

      This Agreement shall be binding upon and inure to the benefit of the
respective successors and assigns of the parties hereto, and shall remain in
full force and effect (and the Bank shall be entitled to rely thereon,
notwithstanding payment of all Obligations of the Borrower to the Bank at any
time or times) until terminated as to future transactions by written notice from
either party to the other party of the termination hereof; provided that any
such termination shall not release or affect any Collateral in which the Bank
already has a security interest or any Obligations incurred or rights accrued
hereunder prior to the effective date of such notice (as hereinafter defined) of
such termination.  Notwithstanding any such termination, the Bank shall have a
security interest in all Collateral to secure the payment and performance of
Obligations arising after such termination as a result of commitments or
undertakings made or entered into by the Bank prior to such termination.  The
Bank may transfer and assign this Agreement and deliver the Collateral to the
assignee, who shall thereupon have all the rights of the Bank; and the Bank
shall then be relieved and discharged of any responsibility or liability with
respect to this Agreement and the Collateral.

      This Agreement is intended to take effect as a sealed instrument and has
been executed or completed and is to be performed in the Commonwealth of
Massachusetts, and it and all transactions hereunder or pursuant hereto shall be

                         TRADEMARK SECURITY AGREEMENT
                         ----------------------------


     THIS SECURITY AGREEMENT is entered into as of April 15, 1999, by and
between Sight Resource Corporation, a Delaware corporation having its principal
place of business at 100 Jeffrey Avenue, Holliston, Massachusetts 01746 (the
"Borrower"), and Fleet National Bank, a national banking association organized
and exiting under the laws of the United States of America with a usual place of
business at One Federal Street, Boston, Massachusetts 02110 ("Bank").

     NOW THEREFORE, in consideration of the premises, Borrower hereby agrees
with Bank as follows:

1.   Grant of Security Interest.  Borrower hereby grants to Bank a first
priority security interest in, and conditionally assigns, but does not transfer
title to Bank, all of Borrower's right, title and interest in and to the
following (collectively, the "Collateral") to secure payment and performance of
all obligations of Borrower to Bank whether such obligations are direct or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, including without limitation, those liabilities of Borrower
to Bank pursuant to a Loan Agreement of even date between Bank and Borrower (the
"Loan Agreement") (collectively, the "Obligations").

     The Collateral shall consist of the following:

     (a) Each of the trademarks, and rights and interests protectible as
trademarks, which are presently, or in the future may be, owned, created,
acquired or used (whether pursuant to a license or otherwise) by Borrower, in
whole or in part, and all trademark rights with respect thereto throughout the
world, including all proceeds thereof (including license royalties and proceeds
of infringement suits), and rights to renew and extend such trademarks and
trademark rights;

     (b) All of Borrower's right, title and interest, in and to the trademarks
and trademark registrations listed on Schedule A attached hereto, as the same
may be updated hereafter from time to time;

     (c) All of Borrower's right, title and interest to register trademark
claims under any state or federal trademark law or regulation of any foreign
country, and to apply for, renew and extend the trademark registrations and
trademark rights, the right (without obligation) to sue or bring opposition or
cancellation proceedings in the name of Borrower or in the name of Bank for
past, present and future infringements of the trademarks, registrations or
trademark rights and all rights (but not obligations) corresponding thereto in
the United States and any foreign country, and the associated goodwill;

     (d) All general intangibles relating to the Collateral; and

     (e) All proceeds of any and all of the foregoing (including, without
limitation, license royalties and proceeds of infringement suits) and, to the
extent not otherwise included, all payments under insurance, or any indemnity,
warranty or guaranty payable by reason of loss or damage to or otherwise with
respect to the Collateral.
<PAGE>
 
2.   Warranties and Representations.  Borrower hereby warrants and represents to
Bank the following:

     (a) A true and complete schedule setting forth all federal and state
trademark registrations owned or controlled by Borrower or licensed to Borrower,
together with a summary description and full information in respect of the
filing or issuance thereof and expiration dates is set forth on Schedule A;

     (b) To the best of Borrower's knowledge, each of the trademarks and
trademark registrations is valid and enforceable, and Borrower is not presently
aware of any past, present or prospective claim by any third party that any of
the trademarks are invalid or unenforceable, or that the use of any trademarks
violates the rights of any third person, or of any basis for any such claims;

     (c) To the best of Borrower's knowledge, Borrower is the sole and exclusive
owner of the entire and unencumbered right, title and interest in and to each of
the trademarks and trademark registrations free and clear of any liens, charges
and encumbrances, including, without limitation, pledges, assignments, licenses,
shop rights and covenants by Borrower not to sue third persons;

     (d) Borrower has used and will continue to use proper statutory notice in
connection with its use of each of the trademarks;

     (e) Borrower has used and will continue to use consistent standards of high
quality (which may be consistent with Borrower's past practices) in the
manufacture, sale and delivery of products and services sold or delivered under
or in connection with the trademarks, including, to the extent applicable, in
the operation and maintenance of its merchandising operations, and will continue
to maintain the validity of the trademarks;

     (f) Except for the filing of financing statements with the Secretary of the
Commonwealth  of Massachusetts, the Town Clerk of Holliston, Massachusetts and
the City Clerk of Malden, Massachusetts under the Uniform Commercial Code and
filings with the United States Patent and Trademark Office necessary to perfect
the security interests created hereunder, no authorization, approval or other
action by, and no notice to or filing with, any governmental authority or
regulatory body is required either for the grant by Borrower of the security
interest hereunder or for the execution, delivery or performance of this
Agreement by Borrower or for the perfection of or the exercise by Bank of its
rights hereunder to the Collateral in the United States.

3.   After-Acquired Trademark Rights.  If Borrower shall obtain rights to any
new trademarks, the provisions of this Agreement shall automatically apply
thereto.  Borrower shall give prompt notice in writing to Bank with respect to
any such new trademarks or renewal or extension of any trademark registration.
Borrower shall bear any reasonable expenses incurred in connection with future
applications for trademark registration.

                                       2

4.   Litigation and Proceedings.  Borrower shall commence and diligently
prosecute in its own name, as the real party in interest, for its own benefit,
and its own expense, such suits, administrative proceedings or other actions for
infringement or other damages as are in its reasonable business judgment
necessary to protect the Collateral.  Borrower shall provide to Bank any
information with respect thereto requested by Bank.  Bank shall provide at
Borrower's expense all necessary cooperation in connection with any such suit,
proceeding or action, including, without limitation, joining as a necessary
party.  Following Borrower's becoming aware thereof, Borrower shall notify Bank
of the institution of, or any adverse determination in, any proceeding in the
United States Patent and Trademark Office, or any United States, state or
foreign court regarding Borrower's claim of ownership in any of such trademarks,
its right to apply for the same, or its right to keep and maintain such
trademark rights.

5.   Power of Attorney.  Borrower grants Bank a power of attorney (which shall
not be exercised absent the occurrence of an Event of Default hereunder), having
the full authority, and in the place of Borrower and in the name of Borrower,
from time to time in Bank's discretion to take any action and to execute any
instrument which Bank may deem reasonably necessary or advisable to accomplish
the purposes of this Agreement, including, without limitation, as may be subject
to the provisions of the Loan Agreement:

     (a) To endorse Borrower's name on all applications, documents, papers and
instruments necessary for Bank to use or maintain the Collateral;

     (b) To ask, demand, collect, sue for, recover, impound, receive and give
acquittance and receipts for money due or to become due under or in respect of
any of the Collateral;

     (c) To file any claims or take any action or institute any proceedings that
Bank may deem necessary or desirable for the collection of any of the Collateral
or otherwise to enforce Bank's rights with respect to any of the Collateral and
to assign, pledge, convey or otherwise transfer title in or dispose of the
Collateral to any person.

7.   Right to Inspect.  Borrower grants to Bank and its employees and agents the
right to visit Borrower's plants and facilities which manufacture, inspect or
store products sold under any of the trademarks, and to inspect the products and
quality control records relating thereto at reasonable times during regular
business hours upon reasonable prior notice.

8.   Events of Default.  Any of the following events shall be an Event of
Default:

     (a) Borrower fails to make any payment of principal or interest or any
other payment on any Obligation when due and payable (beyond any applicable
grace period), by acceleration or otherwise; and

     (b) the occurrence of an Event of Default as that term is defined in the
Loan Agreement after the expiration of any applicable grace period or
termination for any reason of the Loan Agreement.

                                       3
<PAGE>
 
9.   Specific Remedies.  Upon the occurrence of any Event of Default:

     (a) Bank may cease advancing money or extending credit to or for the
benefit of Borrower under the Loan Agreement or under any other agreement
between Borrower and Bank.

     (b) Bank may declare all Obligations to be due and payable immediately,
whereupon they shall immediately become due and payable without presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived
by Borrower;

     (c) Bank may set off against the Obligations all Collateral, balances,
credits, deposits, accounts or moneys of Borrower then or thereafter held with
Bank, including amounts represented by certificates of deposit;

     (d) Bank may notify licensees to make royalty payments on license
agreements directly to Bank;

     (e) Bank may sell or assign the Collateral and associated goodwill at
public or private sale for such amounts, and at such time or times as Bank deems
advisable.  Any requirement of reasonable notice of any disposition of the
Collateral shall be satisfied if such notice is sent to Borrower ten (10) days
prior to such disposition.  Borrower shall be credited with the net proceeds of
such sale only when they are actually received by Bank, and Borrower shall
continue to be liable for any deficiency remaining after the Collateral is sold
or collected;

     (f) If the sale is to be a public sale, Bank shall also give notice of the
time and place by publishing a notice one time at least ten (10) calendar days
before the date of the sale in a newspaper of general circulation in the county
in which the sale is to be held; and

     (g) To the maximum extent permitted by applicable law, Bank may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a credit
on account of the purchase price of any Collateral payable by Bank at such sale.

10.  Governing Law.  All acts and transactions hereunder and the rights and
obligations of the parties hereto shall be governed, construed and interpreted
in accordance with the laws of the Commonwealth of Massachusetts.
