effective.

      Domestic Rate Loan. All or any portion of any Advance or the Loan which
bears interest at the Domestic Rate.

      Eurocurrency Reserve Rate. For any day with respect to a LIBOR Rate Loan,

relating to such reserve requirements) against "Eurocurrency

                                       1

commencing on the date of the Advance of such Loan and ending on the last day of
one of the periods set forth below (i) for any Domestic Rate Loan, the last day

all of the foregoing provisions relating to Interest Periods are subject to the
following:

            (A) if any Interest Period with respect to a LIBOR Rate Loan would
      otherwise end on a day that is not a LIBOR Business Day, that Interest
      Period shall be extended to the next succeeding LIBOR Business Day unless
      the result of such extension would be to carry such Interest Period into
      another calendar month, in which event such Interest Period shall end on
      the immediately preceding LIBOR Business Day;

            (B) if any Interest Period with respect to a Domestic Rate Loan

      end on the next succeeding Business Day;

            (C) if the Borrower shall fail to give notice as provided in
      Paragraph 6, herein, the Borrower shall be deemed to have requested a
      conversion of the affected LIBOR Rate Loan to a Domestic Rate Loan on the
      last day of the then current Interest Period with respect thereto;

            (D) any Interest Period relating to any LIBOR Rate Loan that begins
      on the last LIBOR Business Day of a calendar month (or on a day for which
      there is no numeri cally corresponding day in the calendar month at the
      end of such Interest Period) shall end on the last LIBOR Business Day of a
      calendar month; and

                                       2
<PAGE>

            (E) any Interest Period relating to any LIBOR Rate Loan that would
      otherwise extend beyond the Maturity Date shall end on the Maturity Date.

the annual rate of interest determined by the Lender on the second Business Day
prior to the first day of such Interest Period to be the rate at which deposits

interbank market may be selected by the Lender in its sole discretion, acting in
good faith, at the time of determination and in accordance with the usual
practice in such market for delivery on the first day of such Interest Period
for the number of days comprised therein and in an amount equal (as nearly as
may be) to the principal amount of such LIBOR Rate Loan.

      LIBOR Business Day. Any day on which commercial banks are open for
international business (including dealings in Dollar deposits) in London or such
other eurodollar interbank market as may be selected by the Lender in its sole

interest calculated by reference to the LIBOR Rate.

      Type of Loan. A Domestic Rate Loan or a LIBOR Rate Loan, as the case may

3.    The Loan shall bear interest as follows:

      a.    For each Interest Period:

            i.    To the extent that all or any portion of the Loan is a
                  Domestic Rate Loan, such portion shall bear

                  interest during such Interest Period at the floating rate
                  equal to the Domestic Rate.

            ii.   To the extent that all or any portion of the Loan is a LIBOR
                  Rate Loan, such portion shall bear interest during such
                  Interest Period at the LIBOR Rate determined for such Interest
                  Period.

4.    The Borrower promises to pay interest on the Loan in arrears on each
      Interest Payment Date applicable to such Interest Period.

5.    The Borrower agrees that each request submitted to the Lender requesting
      an Advance shall be accompanied by a written notice of Borrower (the
      "Conversion Request") specifying (i) the requested Type of Loan comprising
      such Advance, (ii) in the case of an Advance comprised of any LIBOR Rate
      Loan, the initial Interest Period; and (iii) the amount of each Type of
      Loan; provided, however, that each LIBOR Rate Loan shall be in an amount
            --------  -------
      of $100,000.00 or integral multiple thereof. A Conversion Request with
      respect to a LIBOR Rate Loan shall be irrevocable and binding on Borrower.
      If no Conversion Request is given by Borrower to the Lender with respect
      to any request for an Advance, the Borrower shall be deemed to have
      selected a Domestic Rate Loan.

6.    Upon notice given by Borrower to the Lender not later than 12:00 noon
      (Boston time) (1) in the case of Conversions into Domestic Rate Loans, on
      the date of the proposed Conversion, and (2) in the case of Conversions
      into LIBOR Rate Loans on the third Business Day prior to the date of the
      proposed Conversion, the Borrower may Convert, on any Business Day, Loans
      of one Type made to the Borrower into Loans of another Type,
      provided, however, that (a) any Conversion of LIBOR Rate Loans may be made
      --------  -------
      only on the last day of the respective Interest Period for such Loans, (b)
      any Loan Converted to a LIBOR Rate Loan shall be in an amount of
      $100,000.00 or integral multiple thereof, and (c) no Advance may be
      Converted to a LIBOR Rate Loan when any Default or Event of Default has
      occurred and is continuing. Each such Conversion Request shall be by
      telephone, telecopy, telex or cable, in each case confirmed immediately in
      writing in the manner specified for notices herein, and shall, within the
      restrictions specified above, specify (i) the date of such Conversion,
      (ii) the Loans to be Converted, and (iii) if such Conversion is to LIBOR
      Rate Loan the duration of the initial Interest Period for such Loans. Each
      Conversion Request with respect to LIBOR Rate Loans shall be irrev ocable
      and binding on the Borrower.

                                       4
<PAGE>

7.    If after giving a Conversion Request, the Borrower fails to borrow or
      Convert any LIBOR Rate Loan, the Borrower shall indemnify the Lender
      against any loss or expense incurred by the Lender as a result of such
      failure including, without limitation, any loss or expense incurred by
      reason of the liquidation or reemployment of deposits or other funds
      acquired by the Lender to fund or maintain an Advance to be made by the
      Lender and the compensation as provided for in Paragraph 12, herein.

8.    Any Loans of any Type may be continued as such upon the expiration of an
      Interest Period with respect thereto by compliance by the Borrower with
      the notice provisions contained in Paragraph 6, above; provided that no
                                                             --------
      LIBOR Rate Loan may be continued as such when any Default or Event of
      Default has occurred and is continuing, but shall be automatically
      converted to a Domestic Rate Loan on the last day of the first Interest
      Period relating thereto ending during the continuance of any Default or
      Event of Default of which the officers of the Lender active upon the
      Borrower's account have actual knowledge.

9.    In the event that the Borrower does not notify the Lender of its election
      under Paragraph 6, herein, in a timely manner with respect to any Loan
      upon the expiration of the applicable Interest Period, such Loan shall be
      automatically converted to a Domestic Rate Loan at the end of the
      applicable Interest Period.

10.   Notwithstanding anything to the contrary contained herein, in no event may
      the Borrower select more than five (5) Interest Periods to be in effect at
      any one time for any particular Type of Loan.

11.   Each determination of an interest rate by the Lender pursuant hereto shall
      be conclusive and binding upon the Borrower in the absence of manifest
      error.

12.   The Borrower agrees to indemnify the Lender and to hold the Lender
      harmless from and against any loss, cost or expense (including loss of
      anticipated profits) that the Lender may sustain or incur as a consequence
      of (a) an Event of Default by the Borrower in payment of the principal
      amount of or any interest on any LIBOR Rate Loans as and when due and
      payable, including any such loss or expense arising from interest or fees
      payable by the Lender to lenders of funds obtained by it in order to
      maintain its LIBOR Rate Loans, (b) an Event of Default by the Borrower in
      making a borrowing or conversion after the Borrower has given (or is
      deemed to have given) a Conversion Request, or (c) the making of any
      payment of any LIBOR Rate Loan or the making of any conversion of any such
      Loan to a Domestic Rate Loan

                                       5
<PAGE>

      on a day that is not the last day of the applicable Interest Period with
      respect thereto, whether due to voluntary prepayment, payment realized
      from the Collateral or any Guarantor after the occurrence of an Event of
      Default, or otherwise, including interest or fees payable by the Lender to
      lenders of funds obtained by it in order to maintain any such Loans. Such
      loss shall include, without limitation, an amount calculated as follows:

      a.    First, the Lender shall determine the amount by which (i) the total
            amount of interest which would have otherwise accrued hereunder on
            each installment of principal so paid or not borrowed, during the
            period beginning on the date of such payment or failure to borrow
            and ending on the date such installment would have been due (the
            "Reemployment Period"), exceeds (ii) the total amount of interest
            which would accrue, during the Reemployment Period, on any readily
            marketable bond or other obligation of the United States of America
            designated by the Lender in its sole discretion at or about the time
            of such payment, such bond or other obligation of the United States
            of America to be in an amount equal (as nearly as may be) to the
            amount of principal so paid or not borrowed and to have a maturity
            comparable to the Reemployment Period, and the interest to accrue
            thereon to take account of amortization of any discount from par or
            accretion of premium above par at which the same is selling at the
            time of designation. Each sum amount is hereafter referred to as an
            "Installment Amount".

      b.    Second, each Installment Amount shall be treated as payable as of
            the date on which the related principal installment would have been
            payable by the Borrower had such principal installment not been
            prepaid or not borrowed.

      c.    Third, the amount to be paid on each such date shall be the present
            value of the Installment Amount determined by discounting the amount
            thereof from the date on which such Installment Amount is to be
            treated as payable, at the same annual interest rate as that payable
            upon the bond or other obligation of the United States of America
            designated as aforesaid by the Lender.

13.   In the event, prior to the commencement of any Interest Period relating to
      any LIBOR Rate Loan, the Lender shall determine that adequate and
      reasonable methods do not exist for ascertaining the Euro Rate that would
      otherwise determine the rate of interest to be applicable to any LIBOR
      Rate Loan during any Interest Period, the Lender shall

                                       6
<PAGE>

      forthwith give notice of such determination (which shall be conclusive and
      binding on the Borrower) to the Borrower. In such event (a) any Conversion
      Request with respect to LIBOR Rate Loans shall be automatically withdrawn
      and shall be deemed a request for Domestic Rate Loans, (b) each LIBOR Rate
      Loan will automatically, on the last day of the then current Interest
      Period thereof, become a Domestic Rate Loan, and (c) the obligations of
      the Lender to make LIBOR Rate Loans shall be suspended until the Lender
      determines that the circumstances giving rise to such suspension no longer
      exist, whereupon the Lender shall so notify the Borrower.

14.   Notwithstanding any other provisions herein, if any present or future law,
      regulation, treaty or directive or in the interpretation or application
      thereof shall make it unlawful for the Lender to make or maintain LIBOR
      Rate Loans, the Lender shall forthwith give notice of such circumstances
      to the Borrower and thereupon (a) the commitment of the Lender to make
      LIBOR Rate Loans or convert Loans of another type to LIBOR Rate Loans
      shall forthwith be suspended and (b) the LIBOR Rate Loans then outstanding
      shall be converted auto matically to Domestic Rate Loans on the last day
      of each Interest Period applicable to such LIBOR Rate Loans or within such
      earlier period as may be required by law. The Borrower hereby agrees
      promptly to pay the Lender, upon demand, any additional amounts necessary
      to compensate the Lender for any costs incurred by the Lender in making
      any conversion in accordance with this section, including any interest or
      fees payable by the Lender to lenders of funds obtained by it in order to
      make or maintain its LIBOR Rate Loans hereunder and any amount payable as
      provided in Paragraph 12, herein.

15.   The Borrower shall have the right at any time to prepay the Note on or
      before the Maturity Date, as a whole, or in part, subject to the following
      limitations:

      a.    For any Domestic Rate Loan, without premium or penalty, provided
                                                                    --------
            that any amount prepaid shall be accompanied by accrued interest on
            the principal repaid to the date of payment;

      b.    For any LIBOR Rate Loan, upon not less than three (3) Business Days'
            prior written notice to the Lender, without penalty, provided that
                                                                 --------
            (1) each partial prepayment shall be in the principal amount of
            $100,000.00 or an integral multiple thereof, (2) if such prepayment
            is on any day other than the last day of the Interest Period
            relating thereto, such amount prepaid shall be accompanied by any
            additional amounts necessary to compensate the Lender for any costs

                                       7
<PAGE>

            incurred by the Lender in accordance with Paragraph 12, herein,
            including any interest or fees payable by the Lender to lenders of
            funds obtained by it in order to make or maintain its LIBOR Rate
            Loans hereunder and (3) any amount prepaid shall be accompanied by
            accrued interest on the principal repaid to the date of payment.

      c.    If the Loan Documents provide at the time of prepayment for periodic
            principal payments on the Loan, any prepayment of principal shall be
            applied against the scheduled installments of principal due on the
            Loan in the inverse order of maturity. No amount repaid with respect
            to the Loan may be reborrowed.

      d.    In the event that at the time of any such prepayment Loans are
            outstanding of more than one Type, the amount prepaid shall be
            applied first to any Domestic Rate Loan prior to application to any
            LIBOR Rate Loans.

      e.    Any premium due hereunder upon such prepayment shall be due and
            payable upon any prepayment whatsoever, whether voluntary or
            involuntary, to the extent permitted by law, and after acceleration
            of the unpaid principal balance of the Loan after the occurrence of
            an Event of Default.

16.   If any present or future applicable law, which expression, as used herein,
      includes statutes, rules and regulations thereunder and interpretations
      thereof by any competent court or by any governmental or other regulatory
      body or official charged with the administration or the interpretation
      thereof and requests, directives, instructions and notices at any time or
      from time to time hereafter made upon or otherwise issued to the Lender by
      any central bank or other fiscal, monetary or other authority (whether or
      not having the force of law), shall:

            (a) subject the Lender to any tax, levy, impost, duty, charge, fee,
      deduction or withholding of any nature with respect to this Agreement, the
      other Loan Documents, or the Loans (other than taxes based upon or
      measured by the income or profits of the Lender), or

            (b) materially change the basis of taxation (except for changes in
      taxes on income or profits) of payments to the Lender of the principal of
      or the interest on any Loans or any other amounts payable to the Lender
      under this Agreement or the other Loan Documents, or

            (c) impose or increase or render applicable (other than to the
      extent specifically provided for elsewhere in

                                       8
<PAGE>

      this Agreement) any special deposit, reserve, assessment, liquidity,
      capital adequacy or other similar requirements (whether or not having the
      force of law) against assets held by, or deposits in or for the account
      of, or loans by, or commitments of an office of the Lender, or

            (d) impose on the Lender any other conditions or re quirements with
      respect to this Agreement, the other Loan Documents, the Loan, or any
      class of loans or commitments of which any Loan forms a part;

and the result of any of the foregoing is

            (i) to increase the cost to the Lender of making, funding, issuing,
      renewing, extending or maintaining any of the Loans, or

            (ii) to reduce the amount of principal, interest or other amount
      payable to the Lender hereunder on account of any of the Loans, or

            (iii) to require the Lender to make any payment or to forego any
      interest or other sum payable hereunder, the amount of which payment or
      foregone interest or other sum is calculated by reference to the gross
      amount of any sum receivable or deemed received by the Lender from the
      Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by the Lender
at any time and from time to time and as often as the occasion therefor may
arise, pay to the Lender such additional amounts as will be sufficient to
compensate the Lender for such additional cost, reduction, payment or foregone
interest or other sum.

17.   Capital Adequacy. If the Lender shall have determined that the adoption of
      any applicable law, rule, regulation, guideline, directive or request
      (whether or not having force of law) regarding capital requirements, or
      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 Lender with
      any of the foregoing imposes or increases a requirement by the Lender to
      allocate capital resources to the Loans made, or to be made, hereunder,
      which has or would have the effect of reducing the return on the Lender's
      capital to a level below that which the Lender could have achieved (taking
      into consideration the Lender's then existing policies with respect to
      capital adequacy and assuming full utilization of the Lender's capital)
      but for such adoption, change or compliance, by any amount deemed by the
      Lender to be material: (i) the Lender shall promptly

                                       9
<PAGE>

      after its determination of such occurrence give notice thereof to the
      Borrower; and (ii) the Borrower shall pay to the Lender as an additional
      fee from time-to-time on demand such amount as the Lender certifies to be
      the amount that will compensate it for such reduction. In determining such
      amounts, the Lender may use any reasonable averaging and attribution
      methods.

18.   All computations of interest on the Loans and of other fees to the extent
      applicable shall be based on a 360-day year and paid for the actual number
      of days elapsed. Except as otherwise provided in the definition of the
      term "Interest Period" with respect to LIBOR Rate Loans, whenever a
      payment hereunder or under any of the other Loan Documents becomes due on
      a day that is not a Business Day, the due date for such payment shall be
      extended to the next succeeding Business Day, and interest shall accrue
      during such extension.

                                                                    EXHIBIT 10.1

                             MODIFICATION AGREEMENT

                                   ----------

"LOAN ARRANGEMENTS") entered into by and between the Bank and the Obligors,
evidenced by, among other things, the following documents, instruments, and
agreements (hereinafter, together with this Agreement and all documents,
instruments, and agreements executed incidental hereto, and contemplated hereby,
this Agreement, collectively the "LOAN DOCUMENTS"):

     dated April 15, 1999 in the maximum principal amount of $3,000,000.00 made
     by the Obligors payable to the Bank;

          2.  Secured Term Note (hereinafter, the "TERM NOTE") dated April 15,
     1999 in the original principal amount of $7,000,000.00 made by the Obligors
     payable to the Bank;

     dated April 15, 1999 in the maximum principal amount of $10,000,000.00 made
     by the Obligors payable to the Bank;

                    Right to Purchase Shares of Common Stock
                          of Sight Resource Corporation

Common Stock Purchase Warrant No. W-1

     THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION
THEREFROM UNDER SUCH ACT AND ANY APPLICABLE STATE SECURITIES LAWS.  FURTHERMORE,
THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT MAY BE
SOLD OR OTHERWISE TRANSFERRED ONLY IN COMPLIANCE WITH THE CONDITIONS SPECIFIED
IN THIS WARRANT.

                          Common Stock Purchase Warrant

     Sight Resource Corporation, a [Delaware] corporation (together with any
corporation which shall succeed to or assume the obligations of Sight Resource
Corporation hereunder, the "COMPANY"), hereby certifies that, for value
received, Fleet National Bank, or its assigns ("FLEET" or "HOLDER"), is
entitled, subject to the terms set forth below, to purchase from the Company (i)
subject to paragraph (A) below, the First Condition Shares, and (ii) subject to
paragraph (B) below, the Second Condition Shares, at any time and from time to
time on and after the respective dates on which this Warrant becomes exercisable
for First Condition Shares and the Second Condition Shares as determined
pursuant to Section 2.1 below until the expiration hereof pursuant to Section
2.3 below, at a purchase price per share equal to the Exercise Price.  The
Warrant Stock and the Exercise Price are subject to adjustment from time to time
as provided herein.

(A) First Condition Shares.  This Warrant shall become exercisable for Fifty
Thousand (50,000) shares (the "FIRST CONDITION SHARES") of Warrant Stock
(subject to any and all adjustments as provided herein, including without
limitation any adjustments in connection with events occurring prior to the date
on which this Warrant first becomes exercisable for the First Condition Shares)
on and as of 5:00 PM, Eastern time, on August 31, 2000, if the Borrower (as
defined in that certain Loan Agreement dated as of March 31, 2000 by and among
Fleet, the Company and the other parties named therein, as modified by that
certain Modification Agreement of even date herewith (the "LOAN AGREEMENT")) on
or before such date shall not have repaid in full all principal advances by
Fleet under the Loan Agreement and otherwise fully and timely performed all of
its obligations (including without limitation payment of all accrued interest,
late payment fees and other charges) thereunder; provided, that notwithstanding
that the Borrower shall not have repaid in full all

                                       1
<PAGE>

principal advances by Fleet under the Loan Agreement and otherwise fully and
timely performed all of its obligations (including without limitation payment of
all accrued interest, late payment fees and other charges) thereunder on or
before August 31, 2000, this Warrant shall not become exercisable for the First
Condition Shares until September 30, 2000 if (i) on or before August 31, 2000
the Company shall have delivered to Fleet an executed commitment letter from one
or more third party financial institutions acceptable to Fleet in its sole
discretion providing for the refinancing by such institution(s) of all
outstanding principal, accrued interest and other charges then outstanding under
the Loan Agreement, where the closing of such refinancing is stated therein to
occur no later than September 30, 2000 and such closing is subject only to
execution of a definitive agreement with respect thereto and to no other
contingencies or conditions precedent, and (ii) (a) the closing of such
refinancing does not occur, for any reason or no reason, on or before September
30, 2000, or (b) the Borrower otherwise, on or before September 30, 2000, have
repaid in full all principal advances by Fleet under the Loan Agreement and
otherwise fully and timely performed all of its obligations (including without
limitation payment of all accrued interest, late payment fees and other charges)
thereunder.

     (B) Second Condition.  This Warrant shall become exercisable for Fifty
Thousand (50,000) additional shares (the "SECOND CONDITION SHARES") of Warrant
Stock (subject to any and all adjustments as provided herein, including without
limitation any adjustments in connection with events occurring prior to the date
on which this Warrant first becomes exercisable for the Second Condition Shares)
on and as of 5:00 PM, Eastern time, on December 31, 2000, if the Borrower on or
before such date shall not have repaid in full all principal advances by Fleet
under the Loan Agreement and otherwise fully and timely performed all of its
obligations (including without limitation payment of all accrued interest, late
payment fees and other charges) thereunder.

     For purposes hereof:

     "EXERCISE PRICE" means (subject to any and all adjustments as provided
herein), the Fair Market Value, as determined pursuant to Section 2.1 below, of
a share of Warrant Stock on and as of the date on which this Warrant first
becomes exercisable as to the First Condition Shares.

     "WARRANT STOCK" means shares of Common Stock or Other Securities issuable
upon exercise of this Warrant.

1. DEFINITIONS.  In addition to the terms which are defined in the body of this
Warrant, certain terms used in this Warrant are defined in Section 15 hereof.

2. EXERCISE OF WARRANT.

   2.1 Exercise.  This Warrant may be exercised prior to its expiration at any
time and from time to time on and after the date(s), if any, on which this
Warrant becomes exercisable for the First Condition Shares and the Second
Condition Shares, respectively by surrender of this Warrant, with the form of
Notice of Exercise or Conversion at the end hereof duly executed by such holder,
to the Company at its principal office, accompanied by payment, by certified or
official bank check payable to the

                                       2
<PAGE>

order of the Company or by wire transfer to its account, in the amount obtained
by multiplying the number of shares of Common Stock for which this Warrant is
then being exercised by the Exercise Price then in effect. In the event the
Warrant is not exercised in full, the Company, at its expense, will forthwith
issue and deliver to or upon the order of the holder hereof a new Warrant or
Warrants of like tenor, in the name of the holder hereof or as such holder (upon
payment by such holder of any applicable transfer taxes) may request, calling in
the aggregate on the face or faces thereof for the number of shares of Common
Stock equal to the balance of the number shares then purchasable under this
Warrant. Upon any exercise of this Warrant, in whole or in part, the holder
hereof may, in lieu of paying the aggregate Exercise Price which otherwise would
be payable with respect to the shares of Warrant Stock for which this Warrant is
then being exercised (collectively, the "EXERCISE SHARES"), (a) in the event the
holder of this Warrant is also the holder of a promissory note of the Company,
convert a like amount of outstanding principal and/or interest amount of such
note into such number of Common Stock, or (b)surrender this Warrant to the
Company together with a notice of cashless exercise, in which event the Company
shall issue to the Holder the number of shares of Warrant Stock determined as
follows:

                    X = Y (A-B)/A
     where:
                    X = the number of shares of Warrant Stock to be issued
                    to the holder.

                    Y = the number of  shares of Warrant Stock with respect to
                    which this Warrant is being exercised.

                    A = the Fair Market Value (as defined below) of one share of
                    the Warrant Stock.

                    B = the Exercise Price.

     For purposes of this Section 2.1, the "Fair Market Value" of one share of
Warrant Stock (the "FAIR MARKET VALUE") at any date shall be determined as
follows:

     (a)  If shares of the same class or series as the Warrant Stock (or shares
     of the Company's Common Stock into which shares of Warrant Stock are
     convertible) are at such time listed or admitted for trading on any
     national securities exchange or quoted on the National Quotation Market
     System of the National Association of Securities Dealers, Inc. Automated
     Quotation System ("NASDAQ"), then the Fair Market Value shall be equal to
     the average of the daily closing market prices of such shares over a period
     of five (5) consecutive trading days prior to the day on which Fair Market
     Value is being determined.  As used in this subparagraph (a), "market
     price" for each such trading day shall be the average of the closing prices
     on such day of such shares on all domestic primary national securities
     exchanges on which such shares are then listed, or, if there shall have
     been no sales on any such exchange on such day, the average of the highest
     bid and lowest asked prices on all such exchanges at the end of such day,
     or if such shares shall not be so listed, the average of the representative
     bid and asked prices at the end of such trading day as reported by NASDAQ.

                                       3
<PAGE>

     (b)  If shares of the same class or series as the Warrant Stock (or shares
     of the Company's Common Stock into which shares of Warrant Stock are
     convertible) are not at such time listed or admitted for trading on any
     national securities exchange or quoted on NASDAQ, then the Fair Market
     Value of one share of Warrant Stock shall be equal to the fair market value
     of the entire capital equity of the Company taken as a whole, divided by
     the number of shares of Common Stock (on a fully diluted, as converted, as
     exercised basis) then issued (or deemed issued) and outstanding, without
     premium for control and without discount for minority interest or
     restriction on transfer, as determined by the Company's Board of Directors
     in good faith and set forth in writing to Fleet within fifteen (15) days
     after the occurrence of the event which requires the valuation, unless
     Fleet shall object in writing within five (5) days after receipt of the
     Board of Directors' determination, in which case the Fair Market Value
     shall be determined (x) by a reputable independent appraiser selected by
     mutual agreement of the Company and Fleet and set forth in writing to the
     Company and Fleet within thirty (30) days after the occurrence of the event
     which requires the valuation, or (y) (if the Company and Fleet shall have
     been unable to agree upon an appraiser within ten (10) days after Fleet's
     objection to the Board of Directors' determination of Fair Market Value) as
     the average of the two (2) closest appraisals by three (3) reputable
     independent appraisers, one chosen by the Company, one chosen by Fleet, and
     the third selected by the other two (2) appraisers, set forth in writing
     within sixty (60) days after the occurrence of the event which requires the
     valuation.  If the Fair Market Value as determined by appraisal pursuant to
     clause (x) above, or by the average of the appraisals determined in
     accordance with clause (y) above, as the case may be,  is greater than the
     Fair Market Value determined by the Board of Directors by five percent (5%)
     or more, then all expenses of such appraisals shall be paid by the Company,
     and in all other circumstances, such appraisal expenses shall be borne by
     the party engaging such appraiser or, as the case may be, jointly, as to
     the jointly scheduled appraiser pursuant to clause (x) and the third
     appraiser pursuant to clause (y).

     2.2   Warrant Agent  In the event that a bank or trust company shall have
been appointed as trustee for the holder of the Warrant pursuant to Section 6.2
hereof, such bank or trust company shall have all the powers and duties of a
warrant agent appointed pursuant to Section 16 hereof and shall accept, in its
own name for the account of the Company or such successor entity as may be
entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 2.

     2.3   Termination.  This Warrant shall terminate as to the First Condition
Shares and the Second Condition Shares, respectively, at 5:00 PM, Eastern time
on the date that is ten (10) years following the date on which this Warrant
first becomes exercisable as to such shares.

3.   REGISTRATION RIGHTS.

     3.1   Registration Rights.  Not later than January 31, 2001 (the
"Registration Date"), the Company at its sole expense shall cause the First
Condition Shares and the Second Condition Shares, if any, issued or issuable
hereunder to be registered for public re-sale by Fleet in accordance with the
provisions of this Section 3. Notwithstanding the foregoing, if prior to the
Registration Date the Company shall otherwise register with the Securities and
Exchange Commission ("SEC") any shares of Warrant Stock, either for its own
account or the account of any of its securityholders or both, the

                                       4
<PAGE>

Company shall give written notice thereof to Fleet not less than twenty (20)
days prior to the filing of such registration statement with the SEC and shall
cause all shares of Warrant Stock issued and issuable hereunder to be included
therein at the sole expense of the Company; provided, that if any such other
registration by the Company is for a firm commitment underwritten offering or
sale of shares of Warrant Stock and the managing underwriters advise the Company
in writing that marketing factors require a limitation on the number of shares
of Warrant Stock to be offered and sold by stockholders of Company in such
offering, there shall be included in such registration: (i) first, all shares of
Warrant Stock proposed by Company to be sold for its account; and (ii) second,
that number of shares of Warrant Stock, if any, requested to be included in such
registration statement by Fleet and by stockholders of the Company having
contractual rights to include shares in such registration, on a pro rata basis
based upon the number of shares of Warrant Stock Fleet and each such stockholder
beneficially owns.

     3.2   Shelf Registration.  The Company shall prepare and file with the SEC
pursuant to Rule 415 under the Securities Act of 1933, as amended, or any
successor statute (the "Act"), a registration statement on Form S-3 under the
Act or any successor form or, if such form is not then available to the Company,
on such form as permitted by the SEC, for the delayed or continuous offering of
the shares of Warrant Stock issued and issuable hereunder (the "Registration
Statement"), and shall cause such Registration Statement to become effective not
later than the Registration Date.  The Company shall cause such Registration
Statement to remain effective until the earlier to occur of (i) the sale by
Fleet of all shares of Warrant Stock issued and issuable hereunder pursuant
thereto or otherwise, or (ii) two (2) years from the Registration Date (the
"Effective Period").  The Company shall also, in connection with the
Registration Statement or such other registration in which the shares of Warrant
Stock issued and issuable hereunder are included pursuant to Section 3.1 above,
cause the shares of Warrant Stock issued and issuable hereunder to be registered
or qualified under such state securities or "blue sky" laws as Fleet shall
reasonably request and to maintain the effectiveness of such state registrations
and qualifications throughout the Effective Period (or effective period of such
other registration).  At all times during the Effective Period (or effective
period of such other registration) the Company shall provide such number of
copies of the prospectus (as amended or supplemented from time to time) under
the Registration Statement (or such other registration statement) as reasonably
requested by Fleet in order to facilitate its disposition of the shares of
Warrant Stock issued and issuable hereunder pursuant thereto.

     3.3   Expenses of Registration.  All expenses (including without limitation
fees of counsel to Fleet up to a maximum of $20,000.00) incurred in connection
with the Registration Statement and any other registration in which the shares
of Warrant Stock issued and issuable hereunder are included pursuant to Section
3.1 above, including without limitation, all registration, filing and
qualification fees, printing expenses, underwriting fees, discounts and
commissions (other than underwriting fees, discounts and commissions relating
solely to the shares of Warrant Stock issued and issuable hereunder), fees and
disbursements of counsel for the Company and expenses of any special audits
incidental to or required by such registration, shall be borne by the Company.

     3.4   Indemnification.

           (a) The Company will indemnify Fleet and each of its officers,
directors, affiliates and each controlling person of Fleet, in connection with
the Registration Statement and/or

                                       5
<PAGE>

any other registration in which the shares of Warrant Stock issued and issuable
hereunder are included pursuant to Section 3.1 above, and all state
registrations and qualifications in connection therewith, against all claims,
losses, expenses, damages and liabilities (or actions in respect thereto)
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any prospectus, offering circular or other document
incident thereto or forming a part thereof or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statement therein not misleading, or any violation or
alleged violation by the Company of the Act, the Securities Exchange Act of
1934, as amended, and the rules and regulations thereunder ("Exchange Act") or
any state securities law applicable to the Company or any rule or regulation
promulgated any such state law and relating to action or inaction required of
the Company in connection with such Registration Statement or such other
registration, qualification or compliance, and will reimburse Fleet and each of
its officers, directors, affiliates and controlling persons, within a reasonable
amount of time after incurred for any reasonable legal and any other expenses
incurred in connection with investigating, defending or settling any such claim,
loss, damage, liability or action; provided, however, that the indemnity
agreement contained in this subsection 3.4(a) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability, or action if such
settlement is effected without the written consent of the Company (which consent
shall not be unreasonably withheld or delayed); and provided further, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by an
instrument duly executed by such Fleet specifically for use therein.

          (b) Fleet will indemnify the Company, each of its directors and
officers and controlling persons against all claims, losses, expenses, damages
and liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in

Warrant.

of such shares of Warrant Stock, the Company at its expense will promptly
prepare a certificate setting forth such adjustment or readjustment, or stating
the reasons why no adjustment or readjustment is being made, and showing, in
detail, the facts upon which any such adjustment or readjustment is based,
including a statement of (i) the consideration received or receivable by the
Company for any additional shares of Warrant Stock, Common Stock (or Other
Securities) issued or sold or deemed issued or sold,(ii) the number of shares of
Warrant Stock and Common Stock then outstanding or deemed to be outstanding on a

and the number of shares of Warrant Stock and Common Stock to be received upon
exercise of this Warrant and conversion of the shares of Warrant Stock, in
effect immediately prior to such adjustment or readjustment and as adjusted and
readjusted (if required by Section 7) on account thereof. The Company will
forthwith mail a copy of each such certificate to each holder of a Warrant, and
will, on the written request at any time of any holder of a Warrant, furnish to
such holder a like certificate setting forth the calculations used to determine
such adjustment or readjustment. At its option, the holders of a Warrant may
confirm the adjustment noted on the certificate by causing such adjustment to be
computed by the Company's independent accounting firm or another independent
certified public accountant at the expense of the Company.
