The principal business of CUS and CVC is to make investments, side-by-side 
with CVP, in start-up or venture capital situations and in connection with
leveraged buyouts and management buyouts.

        (d) and (e)   To the best knowledge of the Reporting Persons, none of 
the entities or persons identified in this Item 2 has, during the past five
years, been convicted of any criminal proceeding (excluding traffic violations
or similar misdemeanors), nor been a party to a civil proceeding of a judicial
or administrative body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

        The source of the consideration paid by the Reporting Persons was
contributions from the partners of each individual Reporting Person.

ITEM 4. PURPOSE OF TRANSACTION.

        The acquisition of the Securities described in response to Item 1 by the
Reporting Persons was consummated by the Reporting Persons as a long-term
strategic investment in the Company. The acquisition by the Reporting Persons of
the Securities from the Company was consummated on November 25, 1997. The
aggregate consideration paid by the Reporting Persons was $5,082,417. The
consideartion paid by (i) CVP was $3,585,961, (ii) C/S was $732,337, (iii) CUS
was $475,592, and (iv) CVC was $288,527.

        All Securities held by the Reporting Persons are held by the Reporting
Persons for investment purposes. Each Reporting Person may, subject to the
continuing evaluation of the factors discussed herein, acquire from time to time
additional securities (including shares of Common Stock) of the Company in the
open market or in privately negotiated transactions, by exchange offer or
otherwise. Depending on the factors discussed herein, each Reporting Person may,
from time to time, retain or sell all or a portion of his holdings of the
Securities in the open market or in privately negotiated transactions,
including, by way of distribution of some or all of the Securities to their
partners or members, as applicable, the conversion of Preferred Stock into
Common Stock or the exercise of Warrants. Representatives of each Reporting
Person may also have discussions with management regarding methods of increasing
sales, cash flow and profitability. Any actions that any Reporting Person might
undertake will depend upon such person's review of numerous factors, including,
among other things, the availability of Securities of the Company (including
Common Stock) for purchase and the price levels of such shares; general market
and economic conditions; ongoing evaluation of the Company's business operations
and prospects; the relative attractiveness of alternative business and
investment opportunities; the actions of the management and the Board of
Directors of the Company; and other future developments.

        The Reporting Persons acquired 1,452,119 shares of newly issued
Preferred Stock which are convertible into Common Stock. The Preferred Stock is
convertible at the holder's option at any time. The Preferred Stock is
convertible (i) in the first three years, at the Company's option if the 30 day
trading average of the Common Stock is $7.00 per share and (ii) after three
years, at the Company's option if the 30 day trading average of the Common Stock
is $9.00 per share.

        The Reporting Persons also received Warrants to purchase up to 842,294
shares of Common Stock ("Class I (Mirror) Warrants"), which represent 19.9% of
the Company's existing options and warrants (the "Counterpart Warrants") that
have exercise prices ranging from $4.63 per share to $9.90 per share. These
Class I (Mirror) Warrants must be exercised by the Reporting Persons, on the
same terms and conditions as the holders of the Counterpart Warrants,  when the
Counterpart Warrants are exercised. The Reporting Persons cannot force the
holders of the Counterpart Warrants to exercise such Counterpart Warrants and
the Reporting Persons cannot exercise the Class I (Mirror) Warrants unless and
until the holders of Counterpart Warrants exercise such Counterpart Warrants.
The Reporting Persons also received Warrants to purchase 290,424 additional
shares of Common Stock at an exercise price of $7.00 per share and an exercise
period of five years (the "Class II Warrants").

        The terms and conditions for the conversion of the Preferred Stock are
set forth in the Certificate of Designation, Preferences and Rights of
Series B Convertible Preferred Stock (the "Certificate of Designation"),
comprising a portion of the Company's Certificate of Incorporation. The
acquisition was effected pursuant to the Series B Convertible Preferred Stock
Purchase Agreement, dated October 9, 1997, by and among the Company, CVP, C/S,
CUS and CVC, which is attached hereto as Exhibit 2. The terms and conditions of
the Class I (Mirror) Warrants are set forth in the form of Class I (Mirror)
Warrant, which is attached hereto as Exhibit 3. The terms and conditions of the
Class II Warrants are set forth in the form of Class II Warrant, which is
attached hereto as Exhibit 4.

        Under the terms of the Certificate of Designation, the holders of
Preferred Stock, voting as a separate class, shall have the right to elect one
director to the Board of Directors of the Company (the "Series B Director").
Commencing on the earlier to occur of (i) a vacancy on the Board of Directors
due to the resignation, death, retirement or non-election of any member other
than the Series B Director, or (ii) the date of the Company's 1998 annual
meeting of stockholders, the holders of Preferred Stock, voting as a separate
class, shall have the right to elect a second member of the Board of Directors
of the Company. Thereafter, the holders of Preferred Stock shall have the right,
voting as a separate class, to elect two members of the Board of Directors of
the Company until such time as at least one-half but less than all of the
outstanding shares of Preferred Stock have been redeemed, repurchased, retired
or converted into shares of Common Stock of the Company, in which case the
holders of Preferred Stock shall have the right, voting as a separate class, to
elect only one member to the Board of Directors of the Company until such time
as all of the outstanding shares of Preferred Stock have been redeemed,
repurchased, retired or converted into shares of Common Stock.

        The holders of Preferred Stock are entitled to cumulative dividends at
an annual rate of ten percent (10%) times the liquidation preference of $3.50
per share, commencing on and after the third anniversary of the date of original
issuance of the Preferred Stock. In addition, the holders of Preferred Stock
have the right to participate in any dividends paid with respect to the Common
Stock, on the basis of the number of shares of Common Stock into which the
Preferred Stock may be converted.

        Upon a Change of Control of the Company, the holders of Preferred Stock
shall have the right to compel the Company to redeem the Preferred Stock at a
price of 105% of the liquidation preference of $3.50 per share. For purposes of
the Certificate of Designation, the term "Change of Control" is defined as (i)
any person or group obtaining a majority of the securities ordinarily having the
right to vote in an election of the Board of Directors; (ii) during any two year
period, the individuals who at the beginning of the period no longer constitute
a majority of the Board of Directors; (iii) the merger, consolidation,
recapitalization, reorganization, dissolution, or liquidation of the Company as
a result of the current stockholders no longer owning more than 50% of the
voting securities of the Company; (iv) any sale, lease, exchange or other
transfer of all, or substantially all, of the assets of the Company; or (v) the
adoption of a plan leading to the liquidation or dissolution of the Company.

        Other than as set forth in this statement, the Reporting Persons do not
have any present plans or proposals that relate to or would result in any of the
consequences listed in paragraphs (a)-(j) of Item 4 of Schedule 13D, or any
agreement regarding such matters, although they may in the future take actions
which would have such consequences.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

        (a)    The following table sets forth the beneficial ownership of shares
of the Company's Common Stock by each Reporting Person. As of November 25, 1997,
the Company informed the Reporting Persons that there were 8,756,500 shares of

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

* The Class I (Mirror) Warrants represent 19.9% of the Company's existing
options and warrants and carry exercise prices ranging from $4.63 per share to
$9.90 per share. The Reporting Persons must exercise these Class I (Mirror)
Warrants when the Counterpart Warrants are exercised. The maximum number of
shares of Common Stock issuable upon exercise of the Class I (Mirror) Warrants
is included for the purposes of this calculation because the Counterpart
Warrants are exercisable within sixty days by the holders of such Counterpart
Warrants, see Rule 13d-3(d)(1). As described in Item 4, although the Reporting
Persons must exercise the Class I (Mirror) Warrants when the Counterpart
Warrants are exercised, the Reporting Persons cannot force the holders of
Counterpart Warrants to exercise such Counterpart Warrants and the Reporting
Persons cannot exercise the Class I (Mirror) Warrants unless and until the
holders of Counterpart Warrants exercise such Counterpart Warrants.

        The following table sets forth the approximate percentage of Common
Stock of the Company that is beneficially owned by each Reporting Person.**

                                   SECTION 5

           Representations, Warranties and Covenants of the Purchaser

         The Purchaser hereby represents and warrants to and agrees with the
Company, as follows:

         5.1.    Accredited Investor; Experience; Risk.  The Purchaser is an
accredited investor within the definition of Regulation D of the Securities
Act.  The Purchaser has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the purchase
of the Convertible Preferred Stock and Warrants.

         5.2.    Investment.  The Purchaser is acquiring the Convertible
Preferred Stock and Warrants for investment purposes only, for its own account
and not as a nominee or agent for any other Person, and not with a view to, or
for resale in connection with, any distribution thereof in violation of
applicable law.

         5.3.    Authorization.  The Purchaser represents that it has all
requisite power and authority to enter into and perform its obligations under
the Transaction Documents to which it is a party.  The execution, delivery and
performance of the Transaction Documents to which Purchaser is a party have
been duly authorized by all necessary action on the part of Purchaser.  Each
Transaction Document to which the Purchaser is a party has been duly and
validly executed and delivered by the Purchaser and constitutes the legal,
valid and binding obligation of the Purchaser, enforceable against it in
accordance with its terms, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally, and subject, as to enforceability, to
general principles of equity, including principles of commercial
reasonableness, good faith and fair dealing (regardless of whether enforcement
is sought in a proceeding at law or in equity) and except to the extent that
rights to indemnification and contribution under this Agreement may be limited
by federal or state securities laws or public policy relating thereto.

         5.4.    Governmental Consents.  No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state, or local governmental authority on the part of
Purchaser is required in connection with the valid execution and delivery by
the Purchaser of the Transaction Documents to which it is a party, or the
consummation by the Purchaser of the transactions contemplated by the
Transaction Documents to which it is a party, except for such filings as have
been made prior to the Closing.

         5.5.    Brokers' Fees.  No broker, finder, investment banker or other
Person is entitled to any brokerage fee, finder's fee or other commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by the Purchaser.

         5.6.    Unregistered Shares.  The Purchaser understands and
acknowledges that none of the Convertible Preferred Stock, the shares of Common
Stock issuable upon conversion of the Convertible Preferred Stock, the Warrants
or the shares of Common Stock issuable upon exercise





                                     - 22 -
<PAGE>   27
of the Warrants have been registered under the Securities Act or any state
securities laws and are therefore "unregistered securities" as that term is
used in the Securities Act, and as such may not be offered for sale, sold or
otherwise disposed of without such registration or an opinion of counsel
reasonably satisfactory to the Company that such sale or disposition can be
made pursuant to an exemption from registration under the Securities Act and
any applicable state securities laws. Purchaser agrees a legend that reflects
the foregoing shall be placed on any certificates evidencing the securities
purchased herein and that, so long as the legend may remain on such
certificates, that the Company may maintain appropriate "stop transfer" orders
with respect to such securities on its books and records and with those to whom
it may delegate registrar and transfer functions. Purchaser further agrees and
acknowledges that, except as set forth in Section 8.3 of this Agreement, the
Company does not have any obligation or other commitment to register any of the
securities issued or to be issued pursuant to this Agreement.

         5.7.    Access to Information.  The Purchaser acknowledges receipt of
the Company's Annual Report on Form 10-K for the fiscal year ended December 31,
1996 and Quarterly Report on Form 10-Q for the fiscal period ended June 30,
1997.  The Purchaser further represents and acknowledges that it has carefully
read such reports and has been furnished by the Company during the course of
this transaction with all additional information regarding the Company that it
has requested; that Purchaser has been afforded the opportunity to ask
questions of and receive answers from duly authorized officers or other
representatives of the Company concerning the Company and the terms and
conditions of this transaction and has utilized such opportunity to Purchaser's
satisfaction.

         5.8     Restricted Transfer of Securities.  The Purchaser agrees that,
for a period of two (2) years commencing on the date of this Agreement (the
"Restricted Period"), the securities issued or to be issued pursuant to this
Agreement, including without limitation the Registrable Securities
(collectively, the "Issued Securities"), may not be sold, assigned or otherwise
transferred to a Restricted Person without the prior written consent of the
Company.  For purposes of this Section 5.8, "Restricted Person" means any
Person engaged in or intending to be engaged in, either directly or indirectly
(including, without limitation, through an Affiliate or in concert with another
Person), any business in which the Company is operating on the date of the
proposed sale, assignment or transfer.  Following the Restricted Period, the
Issued Securities may be sold, assigned or otherwise transferred without
limitation if the average closing price for the Common Stock quoted on the
Nasdaq National Market System (or on any exchange on which the Common Stock is
then listed) for the thirty (30) trading days immediately prior to the last day
of  the Restricted Period (the "Benchmark Price") is equal to or less than
$12.00 per share.  If the Benchmark Price is greater than $12.00 per share,
then the restrictions on the Issued Securities set forth in the first sentence
of this Section 5.8 shall continue after the Restricted Period.
Notwithstanding anything contained in this Section to the contrary, the
Purchaser may assign any or all of the Issued Securities to partners or
Affiliates of the Purchaser or officers or directors of partners or Affiliates
of the Purchaser without consent of the Company so long as such partner,
Affiliate, officer or director agrees in writing to be bound by the terms of
this Agreement.

conditions upon which the Company proposes to issue the same.  The Purchaser
shall have fifteen (15) days (the "Offer Period") from the giving of such
notice to agree to purchase all (or any part) of its Proportionate Percentage
of New Securities for the price and upon the terms and conditions specified in
the notice by giving written notice to the Company and stating therein the
quantity of New Securities to be purchased.

                 (c)      If the Purchaser fails to provide notice to the
effect that Purchaser agrees to exercise in full such right within the Offer
Period, the Company shall have 125 days thereafter to sell the New Securities
in respect of which the Purchaser's rights were not exercised, at a price and
upon general terms and conditions no more favorable to the buyers thereof than
specified in the Company's notice to Purchaser pursuant to this Section.  If
the Company has not sold the New Securities within such 125-day period, the
Company shall not thereafter issue or sell any New Securities, except by giving
the Purchaser the right to purchase its Proportionate Percentage in the manner
provided above.

         8.3     Company Registration.

                 (a)      If the Company proposes to register any of its
securities either for its own account or the account of a security holder or
holders exercising their respective demand registration rights, other than a
registration relating solely to employee benefit plans, or a registration
relating to a corporate reorganization or other transaction under Rule 145, or
a registration on any registration form that does not permit secondary sales,
the Company will (i) promptly give to the Purchaser and to each Holder written
notice thereof, and (ii) use its best efforts to include in such registration
(and any related qualification under blue sky laws or other compliance), except
as set forth in Section 8.3(b) below, and in any underwriting involved therein,
all the Registrable Securities specified in a written request or requests, made
by the Purchaser and any Holder and received by the Company within fifteen (15)
days after the written notice from the Company described in clause (i) above is
delivered by the Company.

                 (b)      If the registration as to which the Company gives
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Purchaser and the Holders as a part of the written
notice given pursuant to Section 8.3(a).  In such event, the right of the
Purchaser and any Holder to registration pursuant to this Section 8.3 shall be
conditioned upon such participation in such underwriting and the inclusion of
the Purchaser's and the Holder's Registrable Securities in the underwriting to
the extent provided herein.  The Purchaser and all Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders of securities of the Company with registration
rights to participate therein distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
representative of the underwriter or underwriters selected by the Company.

         Notwithstanding any other provision of this Section 8.3, if the
underwriters advise the Company in writing that marketing factors require a
limitation on the number of shares to be





                                     - 27 -
<PAGE>   32
underwritten, the underwriters may (subject to the limitations set forth below)
exclude all Registrable Securities from, or limit the number of Registrable
Securities to be included in, the registration and underwriting.  The Company
shall so advise all holders of securities requesting registration, and the
number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated first to the Company and to
the Purchaser and thereafter to all other holders of securities requesting
registration.  If any person does not agree to the terms of any such
underwriting, he shall be excluded therefrom by written notice from the Company
or the underwriter.  Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

         8.4.    Shelf Registration.

                 (a)      As soon as practicable after Closing, the Company
shall prepare and file with the SEC a registration statement for an offering to
be made on a delayed or continuous basis pursuant to Rule 415 of the Securities
Act (a "Shelf Registration") registering the resale from time to time by the
Purchaser and each Holder of all of the Registrable Securities issuable upon
conversion of the Convertible Preferred Stock (the "Initial Shelf
Registration").  The registration statement for any Shelf Registration shall be
on Form S-3 or another appropriate form permitting registration of such
Registrable Securities for resale by the Purchaser and each Holder in the
manner or manners designated by them, from time to time, which may include an
underwritten offering, subject to the underwriter being reasonably acceptable
to the Company and the Purchaser.  The Company shall use its best efforts to
cause the Initial Shelf Registration to become effective under the Securities
Act as promptly as is practicable and to keep the Initial Shelf Registration
continuously effective under the Securities Act until the end of the
Effectiveness Period.

                 (b)      From and after the  exercise of any Warrant, in whole
or in part, within 45 days after receipt of written notice from the Purchaser
or Holder, the Company shall effect a Shelf Registration for all or a portion
of the Warrant shares which have been theretofore issued to Purchaser or
Holder; provided, however, that (A) the number of Warrant shares sought to be
included in any Shelf Registration shall not be less than 50% of the shares of
Common Stock or other securities for which the Warrant is exercisable and (B)
in no event shall the Company be obligated to effect a Shelf Registration
pursuant to this paragraph on more than one occasion in any 12-month period.

                 (c)      If the Initial Shelf Registration or any Subsequent
Shelf Registration (as defined below) ceases to be effective for any reason at
any time during the Effectiveness Period (other than because all Registrable
Securities shall have been sold or shall have ceased to be Registrable
Securities), the Company shall use its best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
shall within thirty (30) days of such cessation of effectiveness amend the
Shelf Registration in a manner reasonably expected to obtain the withdrawal of
the order suspending the effectiveness thereof, or file an additional Shelf
Registration covering all of the Registrable Securities then outstanding (a
"Subsequent Shelf Registration").  If a Subsequent Shelf Registration is filed,
the Company shall use all reasonable efforts to cause the Subsequent Shelf
Registration to become effective as promptly as is practicable





                                     - 28 -
<PAGE>   33
after such filing and to keep such registration statement continuously
effective until the end of the Effectiveness Period.

                 (d)      The Company shall supplement and amend the Shelf
Registration if required by the rules, regulations or instructions applicable
to the registration form used by the Company for such Shelf Registration, if
required by the Securities Act or the SEC, or if reasonably requested by the
Purchaser or a majority of Holders or by any managing underwriter, if any, of
such Registrable Securities with respect to the offer and sale or other
disposition of the Registrable Securities during the Effective Period.

                 (e)      From time to time, the Company shall (i) prepare and
file with the SEC a post-effective amendment to the Shelf Registration or a
supplement to the related prospectus or a supplement or amendment to any
document incorporated therein by reference or any other required document, so
that such registration statement will not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, so that, as thereafter
delivered to purchasers of the Registrable Securities being sold thereunder,
such prospectus will not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, not misleading; (ii) provide the Purchaser and the Holders with
copies of any registration statement, prospectus, document incorporated by
reference therein, or such other documents filed with the SEC in such numbers
as the Purchaser and the Holders shall reasonably request; and (iii) inform the
Purchaser and the Holders that the Company has complied with its obligations
and that the registration statement and related prospectus may be used for the
purpose of selling all or any of such Registrable Securities (or that, if the
Company has filed a post-effective amendment to the Shelf Registration which
has not yet been declared effective, the Company will notify Purchaser to that
effect, will use its best efforts to secure the effectiveness of such
post-effective amendment and will immediately so notify Purchaser when the
amendment has become effective).

         8.5     Certain Securities Registration Matters.  Whenever the Company
is required under Section 8.3 or 8.4 to effect the registration with the SEC of
any Registrable Securities, the following provisions shall apply:

                 (a)      The Company shall cause the Registrable Securities
covered by such registration statement to be registered with or approved by
such other governmental agencies or authorities as may be necessary by virtue
of the business and operations of the Company to enable Purchaser or Holder to
consummate the disposition of such Registrable Securities.

                 (b)      The Company shall cause all Registrable Securities
covered by any registration statement to be listed with the Nasdaq Stock
Market, or on each securities exchange on which similar securities issued by
the Company are then listed and, unless the same already exists, provide a
transfer agent, registrar and CUSIP number for all such Registrable Securities
not later than the effective date of the registration statement.





                                     - 29 -
<PAGE>   34
                 (c)      The Company shall enter into such customary
agreements (including an underwriting agreement in customary form, if
applicable) and take all such other actions as the Purchaser or Holder or the
underwriters, if any, reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities pursuant to the registration
statement.

                 (d)      The Company shall make available for inspection by
the Purchaser, Holder and any underwriter participating in any disposition
pursuant to such registration statement, and any attorney, accountant or other
agent retained by the Purchaser, Holder or underwriter (collectively, the
"Inspectors"), all financial and other records, pertinent corporate documents
and agreements and access to properties and management and other information of
the Company as shall be necessary to enable them to exercise their due
diligence responsibility, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any Inspector in
connection with such registration statement, provided that any Inspector shall
have first executed and delivered to the Company a confidentiality agreement in
customary form protecting the confidentiality of such information, except as
otherwise required to be disclosed by law.

                 (e)      If the Registrable Securities are to be sold in an
underwritten offering or in a private transaction involving the sale or
transfer of at least forty percent (40%) of the Registrable Securities issuable
upon conversion of the Convertible Preferred Stock acquired pursuant to this
Agreement, the Company shall obtain "cold comfort" letters and updates thereof
from the Company's independent public accountants and an opinion from the
Company's counsel in customary form and covering such matters of the type
customarily covered by "cold comfort" letters and opinion letters as the
managing underwriter or Purchaser, as the case may be, may reasonably request,
and one copy of such "cold comfort" letter and opinion letter shall be provided
to each of the Purchaser and the Holder.

                 (f)      The Purchaser and Holders shall, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 8.5(i), discontinue disposition of its Registrable Securities pursuant
to the registration statement covering such Registrable Securities until
receipt of the copies of the supplemented or amended prospectus and, if so
directed by the Company, the Purchaser and Holders will deliver to the Company
(at the Company's expense) all copies, other than permanent file copies then in
the Purchaser's and Holders' possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice.

                 (g)      All fees and expenses incident to the Company's
performance of or compliance with a registration statement requirement pursuant
to this Agreement shall be borne by the Company whether or not any of the
registration statements become effective, other than commissions and
underwriter's discounts, if any, and transfer taxes payable by Purchaser and/or
the Holder.  Such fees and expenses shall include, without limitation, (i) all
registration and filing fees (including, without limitation, fees and expenses
(x) with respect to filings required to be made with the National Association
of Securities Dealers, Inc. and (y) of compliance with federal securities or
Blue Sky laws (including, without limitation, fees and disbursements of one
counsel to Purchaser in connection with Blue Sky qualifications of the
Registrable Securities under the laws of such





                                     - 30 -
<PAGE>   35
jurisdictions as the managing underwriter, if any, or the Purchaser may
designate)), (ii) printing expenses, (iii) messenger, telephone and delivery
expenses, (iv) reasonable fees and disbursements of counsel for the Company and
one counsel for the Purchaser in connection with the registration, (v) fees and
disbursements of all independent certified public accountants (including the
expenses of any special audit and "comfort" letters required by or incident to
such performance) and (vi) Securities Act liability insurance obtained by the
Company in its sole discretion.  In addition, the Company shall pay its
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expense
of any annual audit, the fees and expenses incurred in connection with the
listing of the Registrable Securities on any securities exchange or the Nasdaq
Stock Market, as the case may be, on which similar securities issued by the
Company are then listed and the fees and expenses of any Person, including
special experts, retained by the Company.  Notwithstanding the provisions of
this subsection, the Purchaser or the Holders, as the case may be, shall pay
all registration expenses to the extent the Company is prohibited by applicable
Blue Sky laws from paying for or on their behalf.

                 (h)      The Company shall use its reasonable best efforts to
register or qualify the Registrable Securities under such securities or Blue
Sky laws in such jurisdictions as the Purchaser or the Holders may reasonably
request; provided that the Company shall not be required in connection
therewith or as a condition thereof to (i) qualify or register as a foreign
corporation in any such jurisdiction, (ii) execute a general or limited consent
to service of process in any such jurisdiction, (iii) make any undertaking with
respect to the conduct of its business, (iv) subject itself to taxation as a
foreign corporation in any such jurisdiction or (v) enter into any agreement
with any state securities or "blue sky" commission or agency, including,
without limitation, any agreement to escrow shares of its capital stock.

                 (i)      If, in the reasonable judgment of the Company, it is
advisable to suspend use of the prospectus for a period of time due to pending
material corporate developments or similar material events that have not yet
been publicly disclosed and as to which the Company believes public disclosure
will be prejudicial to the Company, the Company shall deliver a certificate in
writing, signed by its Chief Executive Officer, Chief Financial Officer or
General Counsel, to the Purchaser and Holders and the managing underwriter, if
any, to the effect of the foregoing and, upon receipt of such certificate,  the
Purchaser's and Holders' selling period will not commence until the Purchaser,
Holders or managing underwriter, if any, has received copies of the
supplemented or amended Prospectus, or until it is or they are advised in
writing by the Company that the Prospectus may be used, and has received copies
of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such Prospectus.  The Company will use all
reasonable efforts to ensure that the use of the Prospectus may be resumed, and
the selling period may commence, upon the earlier of (x) public disclosure of
such pending material corporate development or similar material event or (y) a
determination by the Company that, in the judgment of the Company, public
disclosure of such material corporate development or similar material event
would not be prejudicial to the Company.  Notwithstanding the foregoing, the
Company shall not under any circumstances be entitled to exercise its right
under this Section 8.5(i) to defer the selling period more than one time in any
12-month period or two times in any 24-month period; and provided, further,
that the period in which a selling period is suspended shall not exceed ninety
(90) days.

                 (j)      In the event of the registration or qualification of
any  Registrable Securities with the SEC pursuant to a registration statement,
the Company agrees to indemnify and hold harmless Purchaser, Holders and each
officer, partner, employee, agent and representative of Purchaser and Holders,
each underwriter, broker or dealer, if any, of such Registrable Securities, and
each other Person, if any, who controls Purchaser and Holder, underwriter,
broker or dealer within the meaning of the Securities Act, Exchange Act or any
other applicable securities laws, from and against any and all losses, claims,
damages or liabilities (or actions in respect thereof) (collectively, the
"Losses") joint or several, to which any of them may become subject under the
Securities Act or any other applicable securities laws or otherwise, insofar as
such Losses arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities were registered or qualified under the
Securities Act or any other applicable securities laws, any preliminary
prospectus or final prospectus relating to such Registrable Securities, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, or any
violation by the Company of any rule or regulation under the Securities Act or
any other applicable securities laws applicable to the Company or relating to
any action or inaction required by the Company in connection with any such
registration or qualification and will reimburse Purchasers, each officer,
director, employee, agent and representative of Purchaser, Holders,
underwriter, broker or dealer and each such controlling Person for any legal or
other expenses reasonably incurred by any of them in connection with
investigating or defending any such Loss; provided, however, that the Company
will not be liable in any such case to the extent that any such Loss arises out
of or is based upon untrue statement of a material fact or omission to state a
material fact necessary to make the statements, in light of the circumstances
under which they were made in such registration statement, such preliminary
prospectus, such final prospectus or such amendment or supplement thereto, not
misleading, in reliance upon and in conformity with written information
furnished to the Company by Purchaser, Holders, or any officer, partner,
employee, agent and representative thereof specifically and expressly for use
in the preparation thereof,or any violation of any rule or regulation under the
Securities Act or applicable securities laws, in which case such person agrees
to indemnify and hold harmless the Company and its Affiliates from and against
any and all Losses, joint or several, to which any of them may become subject
under the Securities Act or any other applicable securities laws or otherwise;
and provided, further, that the Company shall not be liable to any Person who
participates as an underwriter in the offering or sale of Registrable
Securities or any other Person, if any, who controls such underwriter within
the meaning of the Securities Act, in any such case to the extent that any such
Loss (or action or proceeding in respect thereof) or expense arises out of such
Person's failure to send or give a copy of the Prospectus, as the same may be
then supplemented or amended, to the Person asserting an untrue statement or
alleged untrue statement or omission or alleged omission at or prior to the
written confirmation of the sale of Registrable Securities to such Person if
such statement or omission was corrected in such Prospectus so long as such
Prospectus, and any amendments or supplements thereto, have been furnished to
such underwriter in sufficient numbers and in a timely- manner to permit
distribution thereof.

                 Promptly after receipt by a Person entitled to indemnification
under this Section 8.5(j) (an "Indemnified Party") of notice of the
commencement of any action or claim relating to any





                                     - 32 -
<PAGE>   37
registration statement as to which indemnity may be sought hereunder, such
Indemnified Party will, if a claim for indemnification hereunder in respect
thereof is to be made against any other party hereto (an "Indemnifying Party"),
give written notice to such Indemnifying Party of the commencement of such
action or claim, but the omission to so notify the Indemnifying Party will not
relieve the Indemnifying Party from any liability that it may have to any
Indemnified Party except to the extent that the Indemnifying Party is actually
prejudiced thereby.  In case any such action is brought against an Indemnified
Party, and it notifies an Indemnifying Party of the commencement thereof, the
Indemnifying Party will be entitled (at its own expense) to participate in and,
to the extent that it may wish, jointly with any other indemnifying party
similarly notified, to assume the defense, with counsel reasonably satisfactory
to such Indemnified Party, of such action provided that the Indemnifying Party
shall not settle or compromise such action, except upon the prior written
consent of the Indemnified Party  and, after notice from the Indemnifying Party
to such Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party will not be liable to such Indemnified Party for any legal
or other expenses subsequently incurred by such Indemnified Party in connection
with the defense thereof, other than the reasonable cost of investigation;
provided, however, that the assumption of such defense shall not give rise in
the reasonable opinion of the Indemnified Party or its counsel to any conflict.
Notwithstanding the foregoing, the Indemnified Party shall have the right to
employ its own counsel in any such case, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Party unless (A) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such suit, action, claim
or proceeding, (B) the Indemnifying Party shall not have employed counsel
(reasonably satisfactory to the Indemnified Party) to take charge of the
defense of such action, suit, claim or proceeding, or (C) such Indemnified
Party shall have reasonably concluded, based upon the advice of counsel, that
there may be defenses available to it that are different from or additional to
those available to the Indemnifying Party which, if the Indemnifying Party and
the Indemnified Party were to be represented by the same counsel, could result
in a conflict of interest for such counsel or materially prejudice the
prosecution of the defenses available to such Indemnified Party.  If any of the
events specified in clauses (A), (B) or (C) of the preceding sentence shall
have occurred or shall otherwise be applicable, then the reasonable fees and
expenses of one counsel or firm of counsel selected by the Indemnified Party
(and reasonably acceptable to the Indemnifying Party) shall be borne by the
Indemnifying Party.  If, in any such case, the Indemnified Party employs
separate counsel, the Indemnifying Party shall not have the right to direct the
defense of such action, suit, claim or proceeding on behalf of the Indemnified
Party and the Indemnified Party shall assume such defense and/or settle or
compromise such action; provided, however, that an Indemnifying Party shall not
be liable for the settlement or compromise of any action, suit, claim or
proceeding effected without its prior written consent, which consent shall not
be unreasonably withheld.

                          (iii)   Notwithstanding the foregoing, to the extent
that the provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with any underwritten public
offering contemplated by this Agreement are in conflict with the foregoing
provisions, the provisions in such underwriting agreement shall be controlling.

<PAGE>   38
                 (k)      The Purchaser and each Holder holding securities
included in any registration shall furnish to the Company such information
regarding the Purchaser or such Holder and the distribution proposed by the
Purchaser or such Holder as the Company may reasonably request in writing and
as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Section 8.

                 (l)      The Company shall not, directly or indirectly, enter
into any merger, consolidation, or reorganization in which the Company shall
not be the surviving corporation unless the proposed surviving corporation
shall, prior to such merger, consolidation, or reorganization, agree in writing
to assume the obligations of the Company under this Section, and for that
purpose references hereunder to "Registrable Securities" shall be deemed to be
references to the securities that the Purchaser or Holders, as the case may be,
would be entitled to receive in exchange for Registrable Securities under any
such merger, consolidation, or reorganization; provided, however, that the
provisions of this Section shall not apply in the event of any merger,
consolidation, or reorganization in which the Company is not the surviving
corporation if the Purchaser and Holders are entitled to receive in exchange
for their Registrable Securities consideration consisting solely of (i) cash,
(ii) securities of the acquiring corporation that may be immediately sold to
the public without registration under the Securities Act, or (iii) securities
of the acquiring corporation that the acquiring corporation has agreed to
register within 90 days of completion of the transaction for resale to the
public pursuant to the Securities Act.

         8.6     Regulatory Matters.  Each of the Company and Purchaser will
(i) make on a prompt and timely basis all governmental or regulatory
notifications, filings or submissions, as necessary for the consummation of the
transactions contemplated hereby, including any filings required pursuant to
the Hart-Scott-Rodino Antitrust Act, if required, (ii) use all reasonable
efforts to cooperate with the other and its representatives in (A) determining
which notifications, filings and submissions are required to be made prior to
the Closing Date with, and which consents, approvals, permits or authorizations
are required to he obtained prior to the Closing Date from, any governmental
authority in connection with the execution, delivery and performance of this
Agreement and the transactions contemplated hereby, and (B) timely making of
all such notifications, filings or submissions and timely seeking all such
consents, approvals, permits or authorizations, and (iii) use all reasonable
efforts to take, or cause to be taken, all other action and do, or cause to be
done, all other reasonable things necessary or appropriate to consummate the
transactions contemplated by this Agreement.  The Purchaser shall have no
obligation to expend any funds in connection with the action to be taken by the
Company pursuant to this section.

         8.7     Access.  So long as the Purchaser holds at least fifteen
percent (15%) of the Convertible Preferred Stock purchased hereunder, subject
to the provisions of Section 8.8 hereof, upon the written request of the
Purchaser, the Company shall afford the Purchaser and its accountants, counsel
and other representatives, full access during normal business hours to all of
its properties, books, contracts, commitments and records, permit them to copy
or make extracts therefrom and, the Company shall furnish promptly to Purchaser
all information concerning its business, properties and personnel as Purchaser
may reasonably request; provided, however, that no investigation pursuant to
this Section 8.7 shall affect any representations or warranties of either





                                     - 34 -
<PAGE>   39
party hereunder.

         8.8     Confidentiality.  From and after the date of this Agreement,
each of the Company and Purchaser agree to hold, and will cause its employees,
agents and representatives to hold, in confidence, unless compelled to disclose
by judicial or administrative process or, in the written opinion of their
counsel, by other requirements of law, information furnished by the Company, on
the one hand, to Purchaser and information furnished by Purchaser, on the other
hand, to the Company in connection with the transactions contemplated by this
Agreement, and each of such persons agree that they shall not release or
disclose such information to any other person, except their respective
officers, directors, partners, employees, auditors, attorneys, financial
advisors and other consultants, advisors and representatives who need to know
such information and who have been informed of the confidential nature of such
information and have been directed to treat such information as confidential.
The foregoing provisions of this Section 8.8 shall not apply to any such
information which (i) becomes generally available to the public other than as a
result of a disclosure by any person bound hereunder, (ii) was available to a
person bound hereunder on a non-confidential basis prior to its disclosure
hereunder, or (iii) becomes available to any person bound hereunder on a non-
confidential basis by virtue of the disclosure thereof by a source other than
the party providing such information in reliance upon the protection of
confidentiality reposed hereby.

         Notwithstanding anything herein to the contrary, from and after the
date of this Agreement, if either party to this Agreement or any agreement
contemplated herein shall be required by law to file as part of any public
record this Agreement or the agreements relating to any transactions
contemplated hereby, both parties shall jointly identify those provisions, if
any, of such agreements that shall remain confidential and shall request and
seek confidential treatment of those provisions in accordance with the
applicable provisions of any applicable  law, rule or regulation, and shall
take all reasonable actions necessary to secure such confidential treatment.

         8.9     Amendment to NASD Listing Application.  As soon as practical
following the execution of this Agreement, the Company shall prepare and file
with the NASD, and obtain the NASD's approval of, an amendment to the Company's
Nasdaq National Market Listing Application reflecting the consummation of the
transactions completed hereby, together with all documents, instruments and
other materials which are or will be required to be filed or delivered under
the Company's Nasdaq listing agreement and the NASD By-Laws.

         8.10    Reservation of Warrant Shares.  From and after the
consummation of the transactions contemplated herein and under the Warrants,
the Company shall at all times reserve for issuance the number of shares of
Common Stock issuable upon exercise of the Warrant on a fully-diluted basis in
accordance with the terms thereof.

(each, an "Indemnified Party"), from and against any and all actual losses,

referred to as a "Loss"), which may be incurred by or asserted





                                     - 38 -
<PAGE>   43
or awarded against any Indemnified Party in connection with or in any manner
arising out of or relating to any investigation, litigation or proceeding or
the preparation of any defense with respect thereto, arising out of or in
connection with or relating to the transactions contemplated by this Agreement
and the other Transaction Documents, except to the extent such Loss is found in
a final judgment by a court of competent jurisdiction to have resulted from
such Indemnified Party's gross negligence or willful misconduct.

                   (b)      An Indemnified Party shall give written notice to
the Company of any claim with respect to which it seeks indemnification within
ten (10) days after the discovery by such parties of any matters giving arise
to a claim for indemnification pursuant to Section 9.11(a); provided that the
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Company of its obligations under this Section 9.11, except to the
extent that the Company is actually prejudiced by such failure to give notice.
In case any such action or claim is brought against any Indemnified Party, the
Company shall be entitled to participate in and, unless in the reasonable good
faith judgment of the Indemnified Party a conflict of interest between such
Indemnified Party and the Company may exist in respect of such action or claim,
to assume the defense thereof, with counsel reasonably satisfactory to the
Indemnified Party and, after notice from the Company to the Indemnified Party
of its election so to assume the defense thereof, the Company shall not be
liable to such Indemnified Party for any legal or other expenses subsequently
incurred by the latter in connection with the defense thereof other than
reasonable costs of investigation.  In any event, unless and until the Company
elects in writing to assume and does so assume the defense of any such action
or claim the Indemnified Party's reasonable costs and expenses arising out of
the defense, settlement or compromise of any such action or claim shall be
Losses subject to indemnification hereunder.  If the Company elects to defend
any such action or claim, then the Indemnified Party shall be entitled to
participate in such defense with counsel of its choice at its sole cost and
expense.  The Company shall not be liable for any settlement of any action or
claim effected without its written consent. Anything in this Section 9.11 to
the contrary notwithstanding, the Company shall not, without the Indemnified
Party's prior written consent, settle or compromise any claim or consent to
entry of any judgment in respect thereof that imposes any future obligation on
the Indemnified Party or that does not include, as an unconditional term
thereof, the giving by the claimant or the plaintiff to the Indemnified Party,
a release from all liability in respect of such claim.

                           SIGHT RESOURCE CORPORATION


No.:___                                                 ____________ __, 1997

THIS CERTIFIES THAT, __________________________ ("Holder"), for value received,
or its registered assigns, is entitled to purchase, on the terms and subject to
the conditions hereinafter set forth, from Sight Resource Corporation, a
Delaware corporation (the "Company"), at any time, and from time to time,
during the period beginning on the date hereof and ending on the earlier of (i)
the date that all of the warrants set forth in Schedule A attached hereto and
incorporated herein by reference (the "Warrants") have been exercised for the
full number of shares issuable thereunder, or (ii) the date that all of the
Warrants shall have expired or otherwise terminated (the "Exercise Period"),
such aggregate number of shares of Common Stock, par value $.01 per share, of
the Company, that constitute 19.9% of the shares of Common Stock of the Company
issued upon exercise of the Warrants.  The aggregate number of such shares
("Mirror Warrant Shares") currently is 842,294 shares of Common Stock, which is
subject to adjustment from time to time pursuant to Section 4 hereof.  The
Company and the Holder acknowledge and agree that the intent of the parties is
that Holder be granted and have the right to exercise this Mirror Warrant to
purchase the number of Mirror Warrant Shares equal to 19.9% of the number of
shares of Common Stock issued upon the exercise of any Warrant from time to
time in the future.

         SECTION 1. EXERCISE PRICE.  The exercise price per each Mirror
Warrant Share at which this Class I (Mirror) Warrant (the "Mirror Warrant") may
be exercised shall be equal to the exercise price per share (the "Mirror
Warrant Exercise Price") pursuant to that Warrant, the exercise of which gave
rise to the right to acquire Mirror Warrant Shares hereunder (the "Counterpart
Warrant"), as adjusted from time to time in accordance with the provisions of
Section 4 hereof.

         SECTION 2. MIRROR WARRANT SHARES.

         2.1      Grant and Exercise of Mirror Warrant Shares. For purposes
hereof, each exercise of a Counterpart Warrant shall constitute a separate
grant of Mirror Warrant Shares subject to this Mirror Warrant (a "Mirror
Grant"). Holder agrees that it shall be obligated to and shall exercise this
Mirror Warrant to purchase the Mirror Warrant Shares pursuant to the Mirror
Grant no later than 60 days following the date of each Mirror Grant, provided,
however, that Holder shall not be





                                       1
<PAGE>   2
required to purchase Mirror Warrant Shares until the applicable aggregate
Mirror Warrant Exercise Price, from time to time, equals or exceeds One Million
Dollars ($1,000,000).  Notwithstanding anything herein to the contrary, Holder
shall have no obligations to exercise this Mirror Warrant and fund the purchase
of Mirror Warrant Shares on or after June 30, 1998 if the Certificate of
Incorporation of the Company has not been amended by such date to provide that
the holders of Series B Convertible Preferred Stock, par value $.01 per share,
of the Company, voting as a separate class, have the right to elect two members
to the Board of Directors of the Company.

         2.2      Terms and Conditions of Mirror Warrant Shares.  Except as
otherwise provided herein, each Mirror Grant shall have terms identical to the
Counterpart Warrant from which it arose, such that each and every term and
condition applicable to the Mirror Warrant Shares pursuant to any Mirror Grant,
including, but not limited to, the manner of exercise of the Mirror Warrant,
the payment of the exercise price of the Mirror Warrant Shares, the
anti-dilution provisions, the lock-up provisions and the registration rights
applicable thereto, shall be identical to the terms and conditions applicable
to the warrant shares issuable under the Counterpart Warrant, and such terms
and conditions shall be incorporated by reference herein.

         2.3.     Counterpart Warrant.  The Company shall attach copies of
each Counterpart Warrant hereto as Schedule B. Upon each exercise of any
Counterpart Warrant, the Company shall promptly provide Holder with written
notice of the (i) the number of shares issued pursuant to such exercise of a
Counterpart Warrant, (ii) the date of exercise, (iii) the applicable exercise
price, (iv) the number of Mirror Warrant Shares granted pursuant to the Mirror
Warrant Grant, (iv) the identity of the Counterpart Warrant, (v) the aggregate
number of Mirror Warrant Shares issuable pursuant to this Mirror Warrant, and

certificate for Mirror Warrant Shares initially issued upon exercise of this
Mirror Warrant, unless at the time of exercise such Warrant Shares are
registered under the Securities Act of 1933, as amended (the "Act"), shall bear
the following legend (and any additional legend required by any securities
exchange upon which such Warrant Shares may, at the time of such exercise, be
listed and any applicable state securities administration or commission) on the
face thereof:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
         ACT OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES LAWS AND MAY
         NOT BE OFFERED, SOLD OR TRANSFERRED UNLESS REGISTERED PURSUANT TO THE
         PROVISIONS OF SUCH LAWS, OR IF, IN THE OPINION OF COUNSEL REASONABLY
         SATISFACTORY TO SIGHT RESOURCE CORPORATION, AN EXEMPTION FROM SUCH
         REGISTRATION IS AVAILABLE.

         2.5.     Acknowledgment of Continuing Obligation.  The Company will, 
at the time of the exercise of this Mirror Warrant, in whole or in part, upon
request of the Holder, acknowledge in writing its continuing obligation to the
Holder in respect of any rights to which the Holder shall continue to be
entitled after such exercise in accordance with this Mirror Warrant, provided,
that the failure of the Holder to make any such request shall not affect the
continuing obligation of the Company to the Holder in respect of such rights.

         2.6.     Investment Representation.  The Holder of this Mirror 
Warrant, by acceptance hereof, acknowledges that this Mirror Warrant and, upon
exercise, the Mirror Warrant Shares, are being acquired solely for the Holder's
own account and not as a nominee for any other party, and for investment and
that the Holder will not offer, sell, transfer, assign or otherwise dispose of
this Mirror Warrant or the Mirror Warrant Shares issued upon exercise hereof,
unless registered under the Act and applicable state securities laws or
pursuant to an opinion of counsel reasonably satisfactory to the Company that
an exemption from registration under such laws is available.  Upon exercise of
this Mirror Warrant, the Holder shall, if requested by the Company, confirm, in
writing, in a form reasonably satisfactory to the Company, that the Mirror
Warrant Shares so purchased are being acquired solely for the Holder's own
account and not as a nominee for any party for investment.

         2.7.     Accredited Investor; Experience; Risk.  The Holder is an 
accredited investor within the definition of Regulation D of the Act.  The
Holder has such knowledge and experience in financial and business matters that
it is capable of evaluating the merits and risks of purchase of the Mirror
Warrants and the Mirror Warrant Shares.

         SECTION 3. OWNERSHIP, TRANSFER.

         3.1.     Ownership of this Mirror Warrant.  The Company may deem and 
treat the person in whose name this Mirror Warrant is registered as the Holder
and owner hereof (notwithstanding any notations of ownership or writing hereon
made by anyone other than the Company) for all purposes and shall not be
affected by any notice to the contrary, until presentation of this Mirror
Warrant for registration of transfer as provided in this Section 3.

         3.2.     Exchange, Transfer and Replacement.  This Mirror Warrant is
exchangeable upon the surrender hereof by the Holder to the Company at its
office or agency for new Mirror Warrants of like tenor and date representing in
the aggregate the right to purchase the number of Mirror Warrant Shares
purchasable hereunder, each of such new Mirror Warrants to represent the
portion of this Mirror Warrant exchanged as shall be designated by the Holder
at the time of such surrender.  Subject to the terms of this Mirror Warrant,
this Mirror Warrant and all rights hereunder are transferable in whole or in
part upon the books of the Company by the Holder in person or by duly
authorized attorney, and a new Mirror Warrant shall be made and delivered by
the Company, of the same tenor as this Mirror Warrant but registered in the
name of the transferee, upon surrender of this Mirror Warrant duly endorsed at
said office or agency of the Company.  Upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Mirror Warrant, and, in case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to it, and upon surrender and cancellation
of this Mirror Warrant, if mutilated, the Company will make and deliver a new
Mirror Warrant of like tenor, in lieu of this Mirror Warrant.  This Mirror
Warrant shall be promptly canceled by the Company upon the surrender hereof in
connection with any exchange, transfer or replacement.  The Company shall pay
all expenses, taxes (other than stock transfer taxes and income taxes) and
other charges payable in connection with the preparation, execution and
delivery of Mirror Warrant Shares pursuant to this Section 3.

        3.3      Restricted Transfer of Securities.  The Holder agrees that,
for a period of two (2) years commencing on the date of this Mirror Warrant
(the "Restricted Period"), the securities issued or to be issued pursuant to
this Mirror Warrant (collectively, the "Issued Securities"), may not be sold,
assigned or otherwise transferred to a Restricted Person without the prior
written consent of the Company.  For purposes of this Section 3.3, "Restricted
Person" means any Person engaged in or intending to be engaged in, either
directly or indirectly (including, without limitation, through an Affiliate or
in concert with another Person), any business in which the Company is operating
on the date of the proposed sale, assignment or transfer of the Issued
Securities.  Following the Restricted Period, the Issued Securities may be
sold, assigned or otherwise transferred without limitation if the average
closing price for the Common Stock quoted on the Nasdaq National Market System
(or on any exchange on which the Common Stock is then listed) for the thirty
(30) trading days immediately prior to the last day of the Restricted Period
(the "Benchmark Price") is equal to or less than $12.00 per share.  If the
Benchmark Price is greater than $12.00 per share, then the restrictions on the
Issued Securities set forth in the first sentence of this Section 3.3 shall
continue after the Restricted Period. Notwithstanding anything contained in
this Section to the contrary, the Holder may assign any or all of the Issued
Securities to partners or Affiliates of the Holder or officers or directors of
partners or Affiliates of the Holder without consent of the Company so long as
such partner, Affiliate, officer or director agrees in writing to be bound by
the terms of this Mirror Warrant.

        SECTION 4. ADJUSTMENT OF EXERCISE PRICE.

        4.1.     Adjustment of Exercise Price.  The Mirror Warrant Exercise
Price shall be adjusted, if and whenever the Company shall issue, grant or
sell, or is, deemed to have issued, granted or sold any shares of Common Stock
of the Company, or options, rights or warrants exercisable for, or convertible
securities convertible into, Common Stock of the Company, for no consideration
or for a consideration per share less than the applicable Mirror Warrant
Exercise Price in effect immediately prior to the time of such issuance or sale
(such issuance being referred to as a "Dilutive Issuance"), in the same manner
and in accordance with the same terms as the exercise price of warrant shares
issuable upon exercise of the Counterpart Warrant shall be adjusted pursuant to
the terms of the Counterpart Warrant, if such terms so provide.

        4.2      Adjustment of Number or Type of Mirror Warrant Shares.   The
number or type of Mirror Warrant Shares shall be adjusted, if and whenever the
Company shall (i) make a Dilutive Issuance, (ii)  subdivide or combine its
securities, (iii) declare a stock dividend, or (iv) effect a reorganization,
reclassification, recapitalization, consolidation or merger, in the same manner
and in accordance with the same terms as the number or type of warrant shares
issuable upon exercise of the Counterpart Warrant shall be adjusted pursuant to
the terms of the Counterpart Warrant, if such terms so provide..

        4.3      Other Adjustments.     Notwithstanding anything herein to
the contrary, the number or type of Mirror Warrant Shares or the Mirror Warrant
Exercise Price, as the case may be, will be adjusted for any other event that
shall cause an adjustment to the number or type of warrant shares or exercise
price of warrant shares under a Counterpart Warrant in the manner and in
accordance





                                       4
<PAGE>   5
with the terms set forth therein, if such terms so provide.

        SECTION 5. COVENANTS OF THE COMPANY.  The Company hereby covenants and
agrees that:

        5.1.     Reservation of Mirror Warrant Shares.  The Company will
reserve and set apart and have at all times, free from pre-emptive rights, a
number of shares of authorized but unissued Common Stock deliverable upon the
exercise of this Mirror Warrant or of any other rights or privileges provided
for herein sufficient to enable it at any time to fulfill all its obligations
hereunder.

        5.2.     Avoidance of Certain Actions. The Company will not, by
amendment of its organizational documents or through any reorganization,
transfer of assets, consolidation, merger, issue or sale of securities or
otherwise, avoid or take any action which would have the effect of avoiding the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in
carrying out all of the provisions of this Mirror Warrant and in taking of all
such action as may be necessary or appropriate in order to protect the rights
of the Holder of this Mirror Warrant against dilution or other impairment.

        5.3.     Governmental Approvals.  If any shares of Common Stock
required to be reserved for the purposes of exercise of this Mirror Warrant
require registration with or approval of any governmental authority under any
Federal law (other than the Act) or under any state law before such shares may
be issued upon exercise of this Mirror Warrant, the Company will, at its
expense, as expeditiously as possible, use its best efforts to cause such
shares to be duly registered or approved, as the case may be.

        5.4.     Binding on Successors.  This Mirror Warrant shall be binding
upon any corporation succeeding to the Company by merger, consolidation or
acquisition of all or substantially all of the Company's assets.

        5.5      Right of Holder.  The Company covenants and agrees that it  is
bound by all the duties and obligations under, and the Holder of any Mirror
Warrant or Mirror Warrant Shares issued pursuant thereto, has all the rights
under, the applicable Counterpart Warrant, to the same extent as if those terms
had been set forth herein.

        SECTION 6. COVENANTS OF HOLDER.   The Holder of any Mirror Warrant or
Mirror Warrant Shares issued pursuant thereto, covenants and agrees that it
will be bound by, and comply with, the terms of the applicable Counterpart
Warrant, to the same extent as if those terms had been set forth herein in
full.

        SECTION 7. NOTICES.  Any notice or other document required or permitted
to be given or delivered to the Holder shall be delivered at, or sent by
certified or registered mail to each Holder at the address listed in the stock
records of the Company or to such other address as shall have been furnished to
the Company in writing by such Holder.  Any notice or other document required
or





                                       5
<PAGE>   6
permitted to be given or delivered to the Company shall be delivered at, or
sent by certified or registered mail to, the principal office of the Company,
at 100 Jeffrey Avenue, Holliston, Massachusetts 01746, Attention: William
McLendon or such other name or address as shall have been furnished to the
Holder by the Company.

        SECTION 8. LIMITATION OF LIABILITY.  No provision hereof, in the
absence of affirmative action by the Holder to purchase Mirror Warrant Shares,
and no mere enumeration herein of the rights or privileges of the Holder, shall
give rise to any liability of the Holder for the Mirror Warrant Exercise Price
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

        SECTION 9. GOVERNING LAW.  This Mirror Warrant shall be governed by,
and construed and enforced in accordance with, the laws of the State of
Delaware, without giving effect to its conflicts of laws provisions.

        SECTION 10. MISCELLANEOUS.  No term of this Mirror Warrant may be
amended, except with the joint written consent of the Holder and the Company. 
The headings in this Mirror Warrant are for purposes of reference only and
shall not affect the meaning or construction of any of the provisions hereof.

Warrant to be signed by its duly authorized officer under its corporate seal,

                           SIGHT RESOURCE CORPORATION



No.:___                                                   ____________ __, 1997

THIS CERTIFIES THAT, __________________________ ("Holder"), for value received,
or its registered assigns, is entitled to purchase, on the terms and subject to
the conditions hereinafter set forth, from Sight Resource Corporation, a
Delaware corporation (the "Company"), at any time, and from time to time,
during the period beginning on the date hereof and ending on the fifth
anniversary of the date hereof, that number of shares (the "Warrant Shares") of
common stock, par value One Cent ($0.01) per share, of the Company (the "Common
Stock"), as determined in accordance with the provisions of Section 2 hereof.

                 SECTION 1. EXERCISE PRICE.  The exercise price per Warrant
Share at which this Class II Warrant (the "Warrant") may be exercised shall be
equal to Seven Dollars ($7.00) per share of Common Stock (the "Exercise
Price"), as adjusted from time to time in accordance with the provisions of
Section 4.4 hereof.

                 SECTION 2. EXERCISE OF WARRANT.

                 2.1.   Number of Warrant Shares for Which Warrant is
Exercisable.  The number of Warrants Shares for which this Warrant may be
exercised at any time prior to its expiration shall be determined by (a)
multiplying Two Hundred Ninety Thousand Four Hundred Twenty-Four (290,424) by
the Exercise Price and (b) dividing the result by the reference price (the
"Reference Price") initially equal to the Exercise Price or, in case an
adjustment of the Reference Price has taken place pursuant to the provisions of
Section 4 of this Warrant, then by the Reference Price as last adjusted and in
effect at the date of any partial or full exercise of this Warrant.

                 2.2.   Procedure for Exercise of Warrant.

                 (a)    To exercise this Warrant in whole or in part, the
Holder shall deliver to the Company, at its principal executive office (or such
other office of the Company in the United States as the Company may designate
by notice in writing to the Holder), (i) the Warrant Certificate attached





                                       1
<PAGE>   2
hereto completed to specify the fraction of the Warrant which the Holder is
electing to exercise, (ii) consideration in an amount equal to the aggregate
Exercise Price of the Warrant Shares being purchased, consisting of (A) cash or
a certified or official bank check, payable to the order of the Company, (B)
cancellation by the Holder of indebtedness of the Company to the Holder, or (C)
a combination of (A) and (B) above, and (iii) if this Warrant is being
exercised in whole or the last fraction of this Warrant is being exercised,
this Warrant.

                 (b)         Notwithstanding any provisions herein to the
contrary, if the fair market value of one share of Common Stock is greater than
the Exercise Price for one share of Common Stock (at the date of calculation,
as set forth below), in lieu of exercising this Warrant for cash, the Holder
may elect to receive shares of Common Stock equal to the value (as determined
below) of this Warrant (or the portion thereof being canceled) by surrender of
this Warrant at the principal office of the Company, together with the properly
endorsed Warrant Certificate, substantially in the form as attached hereto, in
which event the Company shall issue to the Holder that number of shares of
Common Stock computed using the following formula:

                               WS = WCS (FMV-EP)
                                    ------------
                                      FMV

WHERE:

WS               equals the number of Warrant Shares to be issued to the Holder

WCS              equals the number of shares of Common Stock purchasable under
                 the Warrant or, if only a portion of the Warrant is being
                 exercised, the portion of the Warrant being exercised (at the
                 date of such calculation)

FMV              equals the fair market value of one share of Common Stock (at
                 the date of such calculation)

EP               equals the per share Exercise Price (as adjusted to the date
                 of such calculation) of the Warrant

For purposes of the above calculation, the fair market value ("FMV") of one
share of Common Stock shall be determined in accordance with the provisions of
Section 2.3 hereof.  Notwithstanding the foregoing, where there exists a public
market for the Common Stock at the time of such exercise, the FMV per share
shall be equal to the average of the closing bid and asked prices of the Common
Stock quoted in the Over-The-Counter Market Summary or the average of the last
reported sale price of the Common Stock or the closing price quoted on the
Nasdaq National Market System or on any exchange on which the Common Stock is
listed, whichever is applicable, as published in The Wall Street Journal for
the five (5) trading days prior to the date of determination of the FMV.  Upon
receipt of the Warrant Certificate, the Warrant, or both, as applicable, the
Holder shall be deemed to be the holder of record of the Warrant Shares
issuable upon such exercise, notwithstanding that the stock transfer books of
the Company shall then be closed or that certificates representing such





                                       2
<PAGE>   3
Warrant Shares shall not then be actually delivered to the Holder, and the
Company shall, as promptly as practicable, and in any event within five (5)
business days thereafter, execute or cause to be executed and delivered to the
Holder, or as the Holder may direct, a certificate or certificates representing
the aggregate number of shares of Common Stock specified in said Warrant
Certificate.  Each stock certificate so delivered shall be in such denomination
as may be requested by the Holder.  If this Warrant shall have been exercised
only in part, the Company shall, at the time of delivery of said stock
certificate or certificates, deliver to the Holder a certificate evidencing the
fraction of this Warrant which remains exercisable.  The Company shall pay all
expenses, taxes and other charges payable in connection with the preparation,
execution and delivery of stock certificates pursuant to this Section 2.2,
except that, in case such stock certificates shall be registered in a name or
names other than the name of the Holder, funds sufficient to pay all stock
transfer taxes, which shall be payable upon the execution and delivery of such
stock certificate or certificates, shall be paid by the Holder to the Company
at the time of delivering this Warrant to the Company as mentioned above.

                 2.3          Fair Market Value.  Except as set forth above,
for determining the FMV of one share of Common Stock in connection with a "net
exercise" pursuant to the provisions of Section 2.2 hereof, the following shall
apply:

                             (a)           Agreement of the Company and the
Holder.  If the Company and the Holder can agree in writing as to the FMV, such
agreed value shall be the FMV.  If no agreement on the FMV can be reached
within five (5) days from the date of the exercise of this Warrant, then the
FMV shall be determined pursuant to subsection (b) below.

                             (b)           Third Party Appraisal.  If the FMV
is not agreed upon as provided in subsection (a) above within the period
therein stated, then five (5) days thereafter, an appraiser or appraisers shall
be jointly selected by the Company and the Holder, and the determination of
such jointly selected appraiser or appraisers as to the FMV shall be binding
and conclusive upon all parties.  If the Company and the Holder are unable to
reach an agreement as to an appraiser, the provisions of subsection (c) below
shall apply.

                             For purposes of this subsection (b), the FMV shall
take into account, among other things, earnings and book value of the Company,
but shall not take into account any minority stockholder, marketability or
other such discount.

                             (c)           Additional Appraiser.  If the
Company and the Holder do not agree upon the selection of an appraiser or
appraisers, as provided in subsection (b) within the period therein stated,
then, within three (3) days after the expiration of the five (5) day period
provided for in subsection (b) above, each of the Company and the Holder shall
deliver, by written notice to the other, a list of three appraisers and each of
the Company and the Holder shall select one (1) appraiser from the list
delivered by the other.  In the event either party falls to deliver a list of
appraisers or to select an appraiser from such list within said three (3) day
period, the other party may select an appraiser from its list and such
appraiser shall serve as the sole appraiser.  Each of the appraisers so
selected shall, within ten (10) days of being selected, determine the FMV.  In





                                       3
<PAGE>   4
the event the lower of the two (2) appraisals is at least ninety percent (90%)
of the higher appraisal, then the FMV shall be equal to the average of the two
(2) appraisals. In the event that the lower of the two (2) appearances is less
than ninety percent (90%) of the higher appraisal, then the two (2) appraisers
shall appoint a third appraiser within three (3) days after the end of said ten
(10) day period, and such third appraiser shall, within ten (10) days of being
selected, determine the FMV.

                             The FMV shall be equal to the average of (x) the
third appraisal and (y) whichever of the first two appraisals is closest in
dollars to the third appraisal or equal to the third appraisal if such
appraisal is mid-way between the first two appraisals.  The determination of
such appraiser shall be determinative of the FMV and shall be binding, final
and conclusive on the Company and the Holder.

                             (d)            Costs of Appraisals.  The parties
shall share equally the entire cost of any appraisals hereunder.

                 2.4.        Transfer Restriction Legend.  This Warrant and
each certificate for Warrant Shares initially issued upon exercise of this
Warrant, unless at the time of exercise such Warrant Shares are registered
under the Securities Act of 1933, as amended (the "Act"), shall bear the
following legend (and any additional legend required by any securities exchange
upon which such Warrant Shares may, at the time of such exercise, be listed and
any applicable state securities administration or commission) on the face
thereof

                 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                 ACT OF 1933, AS AMENDED, OR UNDER ANY STATE SECURITIES LAWS
                 AND MAY NOT BE OFFERED, SOLD OR TRANSFERRED UNLESS REGISTERED
                 PURSUANT TO THE PROVISIONS OF SUCH LAWS, OR IF, IN THE OPINION
                 OF COUNSEL REASONABLY SATISFACTORY TO SIGHT RESOURCE
                 CORPORATION, AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

                 2.5.        Acknowledgment of Continuing Obligation.  The
Company will, at the time of the exercise of this Warrant, in whole or in part,
upon request of the Holder, acknowledge in writing its continuing obligation to
the Holder in respect of any rights to which the Holder shall continue to be
entitled after such exercise in accordance with this Warrant, provided, that
the failure of the Holder to make any such request shall not affect the
continuing obligation of the Company to the Holder in respect of such rights.

                 2.6.        Investment Representation.  The Holder of this
Warrant, by acceptance hereof, acknowledges that this Warrant and, upon
exercise, the Warrant Shares, are being acquired solely for the Holder's own
account and not as a nominee for any other party, and for investment and that
the Holder will not offer, sell, transfer, assign or otherwise dispose of this
Warrant or the Warrant Shares issued upon exercise hereof, unless registered
under the Act and applicable state securities laws or pursuant to an opinion of
counsel reasonably satisfactory to the Company that an exemption from
registration under such laws is available.  Upon exercise of this Warrant, the
Holder shall, if requested by the Company, confirm, in writing, in a form
reasonably satisfactory to the Company, that the Warrant Shares so purchased
are being acquired solely for





                                       4
<PAGE>   5
the Holder's own account and not as a nominee for any party for investment.

                 2.7.        Fractional Shares.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.  With respect to any fraction of a share called for upon any exercise
hereof, the Company shall pay to the Holder an amount in cash equal to such
fraction multiplied by the current FMV of a share, determined in accordance
with the provisions of Section 2.3 hereof.

                 2.8         Accredited Investor; Experience; Risk.  The Holder
is an accredited investor within the definition of Regulation D of the Act.
The Holder has such knowledge and experience in financial and business matters
that its capable of evaluating the merits and risks of purchase of the Warrants
and the Warrant Shares.

                 SECTION 3. OWNERSHIP, TRANSFER.

                 3.1.        Ownership of this Warrant.  The Company may deem
and treat the person in whose name this Warrant is registered as the Holder and
owner hereof (notwithstanding any notations of ownership or writing hereon made
by anyone other than the Company) for all purposes and shall not be affected by
any notice to the contrary, until presentation of this Warrant for registration
of transfer as provided in this Section 3.

                 3.2.        Exchange, Transfer and Replacement.  This Warrant
is exchangeable upon the surrender hereof by the Holder to the Company at its
office or agency for new Warrants of like tenor and date representing in the
aggregate the right to purchase the number of Warrant Shares purchasable
hereunder, each of such new Warrants to represent the portion of this Warrant
exchanged as shall be designated by the Holder at the time of such surrender.
Subject to the terms of this Warrant, this Warrant and all rights hereunder are
transferable in whole or in part upon the books of the Company by the Holder in
person or by duly authorized attorney, and a new Warrant shall be made and
delivered by the Company, of the same tenor as this Warrant but registered in
the name of the transferee, upon surrender of this Warrant duly endorsed at
said office or agency of the Company.  Upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon surrender and cancellation of
this Warrant, if mutilated, the Company will make and deliver a new Warrant of
like tenor, in lieu of this Warrant.  This Warrant shall be promptly canceled
by the Company upon the surrender hereof in connection with any exchange,
transfer or replacement.  The Company shall pay all expenses, taxes (other than
stock transfer taxes and income taxes) and other charges payable in connection
with the preparation, execution and delivery of Warrant Shares pursuant to this
Section 3.

                 3.3.        Restricted Transfer of Securities.  The Holder
agrees that, for a period of two (2) years commencing on the date of this
Warrant (the "Restricted Period"), the securities issued or to be issued
pursuant to this Warrant (collectively, the "Issued Securities"), may not be
sold, assigned or otherwise transferred to a Restricted Person without the
prior written consent of the Company.  For purposes of this Section 3.3,
"Restricted Person" means any Person engaged in or intending to





                                       5
<PAGE>   6
be engaged in, either directly or indirectly (including, without limitation,
through an Affiliate or in concert with another Person), any business in which
the Company is operating on the date of the proposed sale, assignment or
transfer of the Issued Securities.  Following the Restricted Period, the Issued
Securities may be sold, assigned or otherwise transferred without limitation if
the average closing price for the Common Stock quoted on the Nasdaq National
Market System (or on any exchange on which the Common Stock is then listed) for
the thirty (30) trading days immediately prior to the last day of  the
Restricted Period (the "Benchmark Price") is equal to or less than $12.00 per
share.  If the Benchmark Price is greater than $12.00 per share, then the
restrictions on the Issued Securities set forth in the first sentence of this
Section 3.3 shall continue after the Restricted Period.  Notwithstanding
anything contained in this Section to the contrary, the Holder may assign any
or all of the Issued Securities to partners or Affiliates of the Holder or
officers or directors of partners or Affiliates of the Holder without consent
of the Company so long as such partner, Affiliate, officer or director agrees
in writing to be bound by the terms of this Warrant.

     SECTION 4. ADJUSTMENT OF REFERENCE PRICE.

     4.1.        Adjustment of Reference Price.  If and whenever
the Company shall issue or sell, or is, in accordance with Section 4.2(a)
through 4.2(h) hereof, deemed to have issued or sold any Securities of the
Company for no consideration or for a consideration per share less than the
applicable Reference Price in effect immediately prior to the time of such
issuance or sale (such issuance being referred to as a "Dilutive Issuance"),
then, forthwith upon such issue or sale, the Reference Price shall be adjusted
by multiplying the Reference Price in effect immediately prior to the Dilutive
Issuance by the fraction:

                                      X+Y
                                      ---
                                      X+Z

WHERE:

X    equals the number of shares of Common Stock issued and outstanding 
     immediately prior to the Dilutive Issuance;

Y    equals the number of shares of Common Stock of the Company which the 
     aggregate net consideration received by the Company in the Dilutive 
     Issuance would have purchased at the Reference Price in effect 
     immediately before the Dilutive Issuance; and

Z    equals the number of shares of Common Stock of the Company issued or 
     deemed issued in the Dilutive Issuance.

By way of illustration, but not limitation, of the foregoing, assume that (a)
Eight Million Five Hundred Thousand (8,500,000) shares of Common Stock are
issued and outstanding as of the date of the Dilutive Issuance, (b) the
Reference Price is equal to Seven Dollars ($7.00). If the Company were to issue
One Hundred Thousand (100,000) shares of Common Stock at a per share price of
Five Dollars ($5.00), then the Reference Price and the number of Warrant Shares
evidenced by this





                                       6
<PAGE>   7
certificate would be adjusted as follows:

                 71,429      equals the number of shares of Common Stock which
                             the aggregate net consideration received by the
                             Company in the Dilutive Issuance would have
                             purchased at the Reference Price in effect
                             immediately before the Dilutive Issuance,
                             calculated as follows: 100,000 shares x ($5.00 /
                             $7.00) = 71,429 shares.

                 100,000     equals the number of shares of Common Stock issued
                             or deemed issued in the Dilutive Issuance.

                 Therefore, the new Reference Price is equal to $6.976
calculated as follows: ($7.00) x [(8,500,000 + 71,429) / (8,500,000 + 100,000]
= $6.976.

For purposes of this Section 4.1, "Securities" means shares of Common Stock of
the Company and any securities or other rights convertible or exchangeable into
or exercisable for shares of Common Stock; provided, however, "Securities"
shall not include (i) Common Stock issued or issuable upon conversion of the
Convertible Preferred Stock issued to Purchaser; (ii) Common Stock issued or
issuable upon exercise of the Warrants issued to Holder, (iii) securities
issued by the Company as part of any public offering pursuant to an effective
registration statement under the Securities Act; (iv) securities issued in
connection with any stock split, stock dividend or recapitalization of the
Company; (v) equity securities and options to purchase equity securities issued
to management, directors or employees of or consultants to the Company pursuant
to plans outstanding as of the date hereof; (vi) equity securities and options
to purchase equity securities issued in accordance with additional stock option
or similar plans approved by the Board or any class of stockholders, as
required; (vii) securities issued in connection with any merger or acquisition
by the Company; and (viii) Common Stock or other securities issued or issuable
upon conversion of rights, options, warrants or convertible securities issued
and outstanding prior to the date hereof.

                 4.2         For purposes of Section 4.1 hereof, the following
Sections 4.2(a) through 4.2(h) shall also be applicable:

                             (a)    Issuance of Rights or Options.  In
case at any time after the date of this Warrant the Company shall in any manner
grant (whether directly or by assumption in a merger or otherwise) any Warrants
or other rights to subscribe for or to purchase, or any options for the
purchase of, Common Stock or any stock or security convertible into or
exchangeable for Common Stock (such warrants, rights or options being called
"Options" and such convertible or exchangeable stock or securities being called
"Convertible Securities") whether or not such Options or the right to convert
or exchange any such Convertible Securities are immediately exercisable, and
the effective price per share for which Common Stock is issuable upon the
exercise of such Options or upon the conversion or exchange of such Convertible
Securities (determined by dividing (i) the total amount, if any, received or
receivable by the Company as consideration for the granting of such Options,
plus the minimum aggregate amount of additional consideration payable to the
Company upon the exercise of all such Options, plus, in the case of such
Options which relate to Convertible 





                                       7
<PAGE>   8

Securities, the minimum aggregate amount of additional consideration, if any,
payable upon the issue or sale of such Convertible Securities and upon the
conversion or exchange thereof, by (ii) the total maximum number of shares of
Common Stock issuable upon the exercise of all such Options or upon the
conversion or exchange of all such Convertible Securities issuable upon the
exercise of such Options) shall be less than the Reference Price in effect
immediately prior to such Dilutive Issuance, then the total maximum number of
shares of Common Stock issuable upon the exercise of such Options or upon
conversion or exchange of the total maximum amount of such Convertible
Securities issuable upon the exercise of such Options shall be deemed to have
been issued for such effective price per share as of the date of granting of
such Options or the issuance of such Convertible Securities and thereafter
shall be deemed to be outstanding.  Except as otherwise provided in Section
4.2(c) hereof, no adjustment of the Reference Price shall be made upon the
actual issuance of such Common Stock or of such Convertible Securities upon
exercise of such Options or upon the actual issue of such Common Stock upon
conversion or exchange of such Convertible Securities.

                          (b)     Issuance of Convertible Securities.  In case
after the date of this Warrant the Company shall in any manner issue (whether
directly or by assumption in a merger or otherwise) or sell any Convertible
Securities, whether or not the rights to exchange or convert any such
Convertible Securities are immediately exercisable, and the effective price per
share for which Common Stock is issuable upon such conversion or exchange
(determined by dividing (i) the total amount received or receivable by the
Company as consideration for the issue or sale of such Convertible Securities
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the conversion or exchange thereof, by (ii) the total
maximum number of shares of Common Stock issuable upon the conversion or
exchange of all such Convertible Securities) shall be less than the Reference
Price in effect immediately prior to such Dilutive Issuance, then the total
maximum number of shares of Common Stock issuable upon conversion or exchange
of all such Convertible Securities shall be deemed to have been issued for such
effective price per share as of the date of the issuance or sale of such
Convertible Securities and thereafter shall be deemed to be outstanding. Except
as otherwise provided in Section 4.2(c) hereof, no adjustment of the Reference
Price shall be made upon the actual issuance of such Common Stock upon
conversion or exchange of such Convertible Securities and if any such issue or
sale of such Convertible Securities is made upon exercise of any Options to
purchase any such Convertible Securities for which adjustments of the Reference
Price have been or are to be made pursuant to other provisions of this Section
4.2, no further adjustment of the Reference Price shall be made by reason of
such issuance or sale.

                          (c)     Change in Option Price or Conversion Rate.
Upon the happening of any of the following events, after the date of this
Warrant, namely, if the purchase price provided for in any Option referred to
in Section 4.2(a) hereof, the additional consideration, if any, payable upon
the conversion or exchange of any Convertible Securities referred to in Section
4.2(a) or 4.2(b) hereof, or the rate at which Convertible Securities referred
to in Section 4.2(a) or 4.2(b) are convertible into or exchangeable for Common
Stock shall change at any time (including, but not limited to, changes under or
by reason of provisions designed to protect against dilution), the Reference
Price at the time of such event shall forthwith be readjusted upward or
downward to the Reference Price which would





                                       8
<PAGE>   9
have been in effect at such time had such Options or Convertible Securities
still outstanding provided for such changed purchase price, additional
consideration or conversion rate, as the case may be, at the time initially
granted, issued or sold.

                          (d)     Consideration for Stock.  In case any shares
of Common Stock,  Options or Convertible Securities shall be issued or sold for
cash, the consideration received therefor shall be deemed to be the amount
received by the Company therefor.  In case any shares of Common Stock, Options
or Convertible Securities shall be issued or sold for a consideration other
than cash, the amount of the consideration other than cash received by the
Company shall be deemed to be the net fair value of such consideration as
determined in good faith unanimously by the Board of Directors.  In case any
Options shall be issued in connection with the issue and sale of other
securities of the Company, together comprising one integral transaction in
which no specific consideration is allocated to such Options by the parties
thereto, such Options shall be deemed to have been issued for such
consideration as determined in good faith unanimously by the Board.

                          (e)     Subdivision or Combination of Shares.  If the
Company, at any time while this Warrant is outstanding, shall subdivide or
combine any class or classes of its Common Stock, the Reference Price shall be
proportionately reduced, in case of subdivision of shares, to reflect the
increase in the total number of shares of Common Stock outstanding as a result
of such subdivision, as at the effective date of such subdivision, or shall be
proportionately increased, in the case of combination of shares, to reflect the
reduction in the total number of shares of Common Stock outstanding as a result
of such combination, as at the effective date of such combination.

                          (f)     Stock Dividends.  If the Company, at any time
while this Warrant is outstanding, shall pay a dividend in, or make any other
distribution of, Common Stock, the Reference Price shall be adjusted, (as at
the date of such payment or other distribution), to that price determined by
multiplying the Reference Price in effect immediately prior such payment or
other distribution, by a fraction (i) the numerator of which shall be the total
number of shares of Common Stock outstanding immediately prior to such dividend
or distribution, and (ii) the denominator of which shall be the total number of
shares of Common Stock outstanding immediately after such dividend or
distribution (plus in the event that the Company paid cash for fractional
shares, the number of additional shares which would have been outstanding had
the Company issued fractional shares in connection with said dividends).

                          (g)     Treasury Shares.  The disposition of any
shares of Common Stock owned or held by or for the account of the Company shall
be considered an issue or sale of Common Stock for the purpose of this Section
4.2.

                 4.3      Reorganization, Reclassification, Recapitalization
Consolidation, Merger or Sale.  If any capital reorganization, reclassification
or recapitalization of the capital stock of the Company, or consolidation or
merger of the Company, or sales of all or substantially all of its assets to
another entity, shall be effected in such a way that holders of Common Stock
shall be entitled to receive stock, securities, cash or assets with respect to
or in exchange for Common Stock, then, as a condition of such reorganization,
reclassification, recapitalization, consolidation, sale or merger,





                                       9
<PAGE>   10
lawful and adequate provisions shall be made whereby each holder of Warrants
shall thereupon have the right and option to receive, upon the basis and upon
the terms and conditions specified herein and in lieu of the Warrant Shares,
such shares of stock, securities, cash or assets as may be issued or payable
with respect to or in exchange for a number of outstanding shares of Common
Stock equal to the number of shares of Warrant Stock as would have been
received upon exercise of the Warrants at the Reference Price then in effect
immediately before such reorganization, reclassification, recapitalization,
consolidation, sale or merger, and in any such case appropriate provisions
shall be made with respect to the rights and interests of the holders to the
end that the provisions hereof (including without limitation provisions for
adjustments of the applicable Reference Price) shall thereafter be applicable,
as nearly as may be practicable, in relation to any rights to acquire or shares
of stock or securities delivered to holders in connection with such
reorganization, reclassification, recapitalization, consolidation, sale or
merger.  Prior to the consummation of any consolidation or merger or sale of
assets of the Company, the successor corporation resulting from such
consolidation or merger, or the purchaser of such assets, shall agree in
writing to be bound by the provisions hereof.

                 4.4      Adjustment of the Exercise Price.  Upon any
adjustment in the number of Warrant Shares purchasable pursuant to this Warrant
as the result of the provisions of this Section 4, the Exercise Price per share
shall be adjusted so that the adjusted Exercise Price shall be equal to the
aggregate Exercise Price payable with respect to all Warrant Shares on the date
hereof divided by the adjusted number of Warrant Shares then purchasable
hereunder as determined pursuant to the provisions of this Section 4.

                 4.5      Minimum Level for Adjustments.  Notwithstanding any
provision to the contrary contained herein, no adjustment of the Reference
Price shall be made if the amount of said adjustment shall aggregate less than
three cents ($.03); provided however, that in such case any adjustment that
would otherwise be required then to be made shall be carried forward and shall
be made at the time of and together with the next subsequent adjustment which,
together with any adjustment so carried forward, shall aggregate at least three
cents ($.03).

                 SECTION 5.   COVENANTS OF THE COMPANY.   The Company  hereby 
covenants and agrees that:

                 5.1.     Reservation of Shares.  The Company will reserve and
set apart and have at all times, free from pre-emptive rights, a number of
shares of authorized but unissued Common Stock deliverable upon the exercise of
the Warrants or of any other rights or privileges provided for herein
sufficient to enable it at any time to fulfill all its obligations hereunder.

                 5.2.     Avoidance of Certain Actions. The Company will not,
by amendment of its organizational documents or through any reorganization,
transfer of assets, consolidation, merger, issue or sale of securities or
otherwise, avoid or take any action which would have the effect of avoiding the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in
carrying out all of the provisions of this Warrant and in taking of all such
action as may be necessary or appropriate in order to protect the





                                       10
<PAGE>   11
rights of the Holder of this Warrant against dilution or other impairment.

                 5.3.     Governmental Approvals.  If any shares of Common
Stock required to be reserved for the purposes of exercise of this Warrant
require registration with or approval of any governmental authority under any
Federal law (other than the Act) or under any state law before such shares may
be issued upon exercise of this Warrant, the Company will, at its expense, as
expeditiously as possible, use its best efforts to cause such shares to be duly
registered or approved, as the case may be.

                 5.4.     Binding on Successors.  This Warrant shall be binding
upon any corporation succeeding to the Company by merger, consolidation or
acquisition of all or substantially all of the Company's assets.

                 SECTION 6.       SHELF REGISTRATION.

                 6.1      Right to Shelf Registration.      From and after any
exercise of this Warrant, in whole or in part, within 45 days after receipt of
written notice from the Holder, the Company shall effect a Shelf Registration
(the "Initial Shelf Registration") for all or a portion of the Warrant Shares
which have been theretofore issued to Holder; provided, however, that (A) the
number of Warrant Shares sought to be included in any Shelf Registration shall
not be less than 50% of the shares of Common Stock or other securities for
which the Warrant is exercisable and (B) in no event shall the Company be
obligated to effect a Shelf Registration pursuant to this Section 6.1 on more
than one occasion in any 12-month period.  For purposes hereof, the term "Shelf
Registration" means the preparation and filing with the Securities and Exchange
Commission (the "SEC") of a registration statement for an offering to be made
on a delayed or continuous basis pursuant to Rule 415 of the Act.  The
registration statement for any Shelf Registration shall be on Form S-3 or
another appropriate form permitting registration of such Warrant Shares for
resale by each Holder in the manner or manners designated by them, including an
underwritten offering, the underwriter to be mutually agreeable to the Company
and the Holders.  The Company shall use its best efforts to cause the Initial
Shelf Registration to become effective under the Act as promptly as is
practicable and to keep the Initial Shelf Registration continuously effective
under the Act until the end of the Effectiveness Period. For purposes of this
Section 6, the term "Effectiveness Period" means the period commencing on the
date of this Warrant and ending on the date that all Warrant Shares that have
been registered are disposed of pursuant to an effective registration statement
under the Act.

                 6.2      Subsequent Shelf Registration.    If the Initial
Shelf Registration or any Subsequent Shelf Registration (as defined below)
ceases to be effective for any reason at any time during the Effectiveness
Period (other than because all Warrant Shares shall have been sold or shall
have ceased to be Warrant Shares), the Company shall use its best efforts to
obtain the prompt withdrawal of any order suspending the effectiveness thereof,
and in any event shall within thirty days of such cessation of effectiveness
amend the Shelf Registration in a manner reasonably expected to obtain the
withdrawal of the order suspending the effectiveness thereof, or file an
additional Shelf Registration covering all of the Warrant Shares included in
the Initial Shelf Registration or Subsequent Shelf that ceased to be effective
as described in this Section 6.2 (a





                                       11
<PAGE>   12
"Subsequent Shelf  Registration").  If a Subsequent Shelf Registration is
filed, the Company shall use all reasonable efforts to cause the Subsequent
Shelf Registration to become effective as promptly as is practicable after such
filing and to keep such registration statement continuously effective until the
end of the Effectiveness Period.

                 6.3      Covenants of the Company.

                          (a)     The Company shall supplement and amend the
Shelf Registration if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration, if required by the Act or the SEC, or if reasonably requested by
a majority of Holders or by any managing underwriter, if any, of such Warrant
Shares with respect to the offer and sale or other disposition of the Warrant
Shares during the Effectiveness Period.

                          (b)     From time to time, the Company shall (i)
prepare and file with the SEC a post-effective amendment to the Shelf
Registration or a supplement to the related prospectus or a supplement or
amendment to any document incorporated therein by reference or any other
required document, so that such registration statement will not contain any
untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not
misleading, so that, as thereafter delivered to purchasers of the Warrant
Shares being sold thereunder, such prospectus will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; (ii) provide the
Holders with copies of any registration statement, prospectus, document
incorporated by reference therein, or such other documents filed with the SEC
in such numbers as the Holders shall reasonably request; and (iii) inform  the
Holders that the Company has complied with its obligations and that the
registration statement and related prospectus may be used for the purpose of
selling all or any of such Warrant Shares (or that, if the Company has filed a
post-effective amendment to the Shelf Registration which has not yet been
declared effective, the Company will notify the Holders to that effect, will
use its best efforts to secure the effectiveness of such post-effective
amendment and will immediately so notify Holders when the amendment has become
effective).

                          (c)     The Company shall cause the Warrant Shares
covered by such registration statement to be registered with or approved by
such other governmental agencies or authorities as may be necessary by virtue
of the business and operations of the Company to enable the Holder to
consummate the disposition of such Warrant Shares.

                          (d)     The Company shall cause all Warrant Shares
covered by the registration statement to be listed with The Nasdaq Stock
Market, Inc., or on each securities exchange on which similar securities issued
by the Company are then listed and, unless the same already exists, provide a
transfer agent, registrar and CUSIP number for all such Warrant Shares not
later than the effective date of the registration statement.

                          (e)     The Company shall enter into such customary
agreements (including an underwriting agreement in customary form, if
applicable) and take all such other actions as the





                                       12
<PAGE>   13
Holder or the underwriters, if any, reasonably request in order to expedite or
facilitate the disposition of such Warrant Shares pursuant to the registration
statement.

                          (f)     The Company shall make available for
inspection by the Holders and any underwriter participating in any disposition
pursuant to such registration statement, and any attorney, accountant or other
agent retained by the Holders or underwriter (collectively, the "Inspectors"),
all financial and other records, pertinent corporate documents and agreements
and access to properties and management and other information of the Company as
shall be necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any Inspector in connection with
such registration statement, provided that any Inspector shall have first
executed and delivered to the Company a confidentiality agreement in customary
form protecting the confidentiality of such information, except as otherwise
required to be disclosed by law.

                          (g)     If the shares are to be sold in an
underwritten offering or in a private transaction involving at least forty
percent (40%) of the Warrant Shares, the Company shall obtain "cold comfort"
letters and updates thereof from the Company's independent public accountants
and an opinion from the Company's counsel in customary form and covering such
matters of the type customarily covered by "cold comfort" letters and opinion
of counsel, respectively, as the Holders or managing underwriter, as the case
may be, may reasonably request, and one copy of such "cold comfort" letter and
opinion letter shall be provided to the Holders.

                          (h)      The Holders shall upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
6.3(k), discontinue disposition of its Warrant Shares pursuant to the
registration statement covering such Warrant Shares until receipt of the copies
of the supplemented or amended prospectus and, if so directed by the Company,
Holders will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies then in the Holders' possession, of the
prospectus covering such Warrant Shares current at the time of receipt of such
notice.

                          (i)     All fees and expenses incident to the
Company's performance of or compliance with a shelf registration requirement
pursuant to this Warrant shall be borne by the Company whether or not any of
the registration statements become effective, other than commissions, and
underwriter's discounts, if any, and transfer taxes payable by the Holders.
Such fees and expenses shall include, without limitation, (i) all registration
and filing fees (including, without limitation, fees and expenses (x) with
respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal securities or Blue
Sky laws (including, without limitation, fees and disbursements of one  counsel
to the Holders in connection with Blue Sky qualifications of the Warrant Shares
under the laws of such jurisdictions as the managing underwriter, if any, or
the Holders may designate)), (ii) printing expenses, (iii) messenger, telephone
and delivery expenses, (iv) reasonable fees and disbursements of counsel for
the Company and one counsel for the Holders in connection with the
registration, (v) fees and disbursements of all independent certified public
accountants (including the expenses of any special audit and "comfort" letters
required by or incident to such performance) and (vi) the Act liability





                                       13
<PAGE>   14
insurance obtained by the Company in its sole discretion.  In addition, the
Company shall pay its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit, the fees and expenses
incurred in connection with the listing of the Warrant Shares on any securities
exchange or the Nasdaq Stock Market, as the case may be, on which similar
securities issued by the Company are then listed and the fees and expenses of
any Person, including special experts, retained by the Company.
Notwithstanding the provisions of this subsection, the Holders, shall pay all
registration expenses to the extent the Company is prohibited by applicable
Blue Sky laws from paying for or on their behalf.

                          (j)     Blue Sky Laws.    The Company shall use its 
reasonable best efforts to register or qualify the Warrant Shares under such
securities or Blue Sky laws in such jurisdictions as the Holders may reasonably
request; provided, however, that the Company shall not be required in
connection therewith or as a condition thereof to (i) qualify or register as a
foreign corporation in any such jurisdiction, (ii) execute a general or limited
consent to service of process in any such jurisdiction, (iii) make any
undertaking with respect to the conduct of its business, (iv) subject itself to
taxation as a foreign corporation in any such jurisdiction, or (v) enter into
any agreement with any state securities or "blue sky" commission or agency,
including, without limitation, any agreement to escrow shares of its capital
stock.

                          (k)     Delay of Offering.    If, in the reasonable 
judgment of the Company, it is advisable to suspend use of the prospectus for a
period of time due to pending material corporate developments or similar
material events that have not yet been publicly disclosed and as to which the
Company believes public disclosure will be prejudicial to the Company, the
Company shall deliver a certificate in writing, signed by its Chief Executive
Officer, Chief Financial Officer or General Counsel, to Holders and the
managing underwriter, if any, to the effect of the foregoing and, upon receipt
of such certificate, the Holders' selling period will not commence until the
Holders or managing underwriter, if any, has received copies of the
supplemented or amended prospectus, or until it is or they are advised in
writing by the Company that the prospectus may be used, and has received copies
of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such prospectus.  The Company will use all
reasonable efforts to ensure that the use of the prospectus may be resumed, and
the selling period may commence, upon the earlier of (x) public disclosure of
such pending material corporate development or similar material event or (y) a
determination by the Company that, in the judgment of the Company, public
disclosure of such material corporate development or similar material event
would not be prejudicial to the Company. Notwithstanding the foregoing, the
Company shall not under any circumstances be entitled to exercise its right
under this Section 6.3(k) to defer the selling period more than one time in any
12-month period or two times in any 24-month period, and the period in which a
selling period is suspended shall not exceed ninety (90) days.

                          (l)     Indemnity.

                                  (i)      In the event of the registration or
qualification of any  Warrant Shares pursuant to a Shelf Registration, the
Company agrees to indemnify and hold harmless





                                       14
<PAGE>   15
Holders and each officer, partner, employee, agent and representative of
Holders, each underwriter, broker or dealer, if any, of such Warrant Shares,
and each other Person, if any, who controls Holders, underwriter, broker or
dealer within the meaning of the Act, the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or any other applicable securities laws, from and
against any and all losses, claims, damages or liabilities (or actions in
respect thereof) (collectively, the "Losses"), joint or several, to which any
of them may become subject under the Act or any other applicable securities
laws or otherwise, insofar as such Losses arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any registration statement under which such Warrant Shares were registered or
qualified under the Act or any other applicable securities laws, any
preliminary prospectus or final prospectus relating to such Warrant Shares, or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
any violation by the Company of any rule or regulation under the Act or any
other applicable securities laws applicable to the Company or relating to any
action or inaction required by the Company in connection with any such
registration or qualification and will reimburse Holders, each officer,
director, employee, agent and representative of Holders, underwriter, broker or
dealer and each such controlling Person for any legal or other expenses
reasonably incurred by any of them in connection with investigating or
defending any such Loss; provided, however, that the Company will not be liable
in any such case to the extent that any such Loss arises out of or is based
upon an untrue statement of a material fact or omission of a material statement
necessary to make the statements, in light of the circumstances under which
they were made in such registration statement, such preliminary prospectus,
such final prospectus or such amendment or supplement thereto, not misleading,
in reliance upon and in conformity with written information furnished to the
Company by Holders, or any officer, partner, employee, agent and representative
thereof specifically and expressly for use in the preparation thereof, or any
violation of any rule or regulation under the Securities Act or applicable
securities laws, in which case such person agrees to indemnify and hold
harmless the Company and its Affiliates from and against any and all Losses,
joint or several, to which any of them may become subject under the Act or any
other applicable securities laws or otherwise; and provided, further, that the
Company shall not be liable to any Person who participates as an underwriter in
the offering or sale of Warrant Shares or any other Person, if any, who
controls such underwriter within the meaning of the  Act, in any such case to
the extent that any such Loss (or action or proceeding in respect thereof) or
expense arises out of such Person's failure to send or give a copy of the
prospectus, as the same may be then supplemented or amended, to the Person
asserting an untrue statement or alleged untrue statement or omission or
alleged omission at or prior to the written confirmation of the sale of Warrant
Shares to such Person if such statement or omission was corrected in such
prospectus so long as such prospectus, and any amendments or supplements
thereto, have been furnished to such underwriter in sufficient numbers and in a
timely-manner to permit distribution thereof.

                                  (ii)     Promptly after receipt by a Person
entitled to indemnification under this Section (an "Indemnified Party") of
notice of the commencement of any action or claim relating to any registration
statement filed pursuant to a Shelf Registration or as to which indemnity may
be sought hereunder, such Indemnified Party will, if a claim for
indemnification hereunder in respect thereof is to be made against any other
party hereto (an "Indemnifying Party"), give written





                                       15
<PAGE>   16
notice to such Indemnifying Party of the commencement of such action or claim,
but the omission to so notify the Indemnifying Party will not relieve the
Indemnifying Party from any liability that it may have to any Indemnified Party
except to the extent that the Indemnifying Party is actually prejudiced
thereby.  In case any such action is brought against an Indemnified Party, and
it notifies an Indemnifying Party of the commencement thereof, the Indemnifying
Party will be entitled (at its own expense) to participate in and, to the
extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense, with counsel reasonably satisfactory to such
Indemnified Party, of such action provided that the Indemnifying Party shall
not settle or compromise such action, except upon the prior written consent of
the Indemnified Party  and, after notice from the Indemnifying Party to such
Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party will not be liable to such Indemnified Party for any legal
or other expenses subsequently incurred by such Indemnified Party in connection
with the defense thereof, other than the reasonable cost of investigation;
provided, however, that the assumption of such defense shall not give rise in
the reasonable opinion of the Indemnified Party or its counsel to any conflict.
Notwithstanding the foregoing, the Indemnified Party shall have the right to
employ its own counsel in any such case, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Party unless (A) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such suit, action, claim
or proceeding, (B) the Indemnifying Party shall not have employed counsel
(reasonably satisfactory to the Indemnified Party) to take charge of the
defense of such action, suit, claim or proceeding, or (C) such Indemnified
Party shall have reasonably concluded, based upon the advice of counsel, that
there may be defenses available to it that are different from or additional to
those available to the Indemnifying Party which, if the Indemnifying Party and
the Indemnified Party were to be represented by the same counsel, could result
in a conflict of interest for such counsel or materially prejudice the
prosecution of the defenses available to such Indemnified Party.  If any of the
events specified in clauses (A), (B) or (C) of the preceding sentence shall
have occurred or shall otherwise be applicable, then the reasonable fees and
expenses of one counsel or firm of counsel selected by the Indemnified Party
(and reasonably acceptable to the Indemnifying Party) shall be borne by the
Indemnifying Party.  If, in any such case, the Indemnified Party employs
separate counsel, the Indemnifying Party shall not have the right to direct the
defense of such action, suit, claim or proceeding on behalf of the Indemnified
Party and the Indemnified Party shall assume such defense and/or settle or
compromise such action; provided, however, that an Indemnifying Party shall not
be liable for the settlement or compromise of any action, suit, claim or
proceeding effected without its prior written consent, which consent shall not
be unreasonably withheld.

                                  (iii)    Notwithstanding the foregoing, to
the extent that the provisions on indemnification and contribution contained in
the underwriting agreement entered into in connection with any underwritten
public offering contemplated by this Agreement are in conflict with the
foregoing provisions, the provisions in such underwriting agreement shall be
controlling.

                          (m)     Information by  the Holders      Each
Holder holding securities included in any registration shall furnish to the
Company such information regarding such Holder and the distribution proposed by
such Holder as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to





                                       16
<PAGE>   17
in this Section 6.3.

                          (n)     Mergers, Etc.  The Company shall not,
directly or indirectly, enter into any merger, consolidation, or reorganization
in which the Company shall not be the surviving corporation unless the proposed
surviving corporation shall, prior to such merger, consolidation, or
reorganization, agree in writing to assume the obligations of the Company under
this Section, and for that purpose references hereunder to "Warrant Shares"
shall be deemed to be references to the securities that the Holders, as the
case may be, would be entitled to receive in exchange for Warrant Shares under
any such merger, consolidation, or reorganization; provided, however, that the
provisions of this Section shall not apply in the event of any merger,
consolidation, or reorganization in which the Company is not the surviving
corporation if Holders are entitled to receive in exchange for their Warrant
Shares consideration consisting solely of (i) cash, (ii) securities of the
acquiring corporation that may be immediately sold to the public without
registration under the Act, or (iii) securities of the acquiring corporation
that the acquiring corporation has agreed to register within 90 days of
completion of the transaction for resale to the public pursuant to the  Act.

                 SECTION 7.       NOTIFICATIONS BY THE COMPANY.  In case at any
time:

                          (a)     the Company shall declare any dividend 
payable in stock upon Common Stock or make any distribution (other than cash 
dividends which are not in a greater amount per share than the most recent 
cash dividend) to the holders of the Common Stock;

                          (b)     the Company shall propose to make an
offer for subscription pro rata to the holders of its Common Stock of any
additional shares of stock of any class or other rights;

                          (c)     there shall be proposed any other transaction 
of a type referred to in Section 4 hereof, and

                          (d)     there shall be proposed a voluntary or 
involuntary dissolution, liquidation or winding-up of the Company;

then, in any one or more of such cases, the Company shall give written notice
to the Holder of the date on which (i) the books of the Company shall close or
a record shall be taken for such dividend, distribution, subscription rights,
or other transaction, and (ii) such reorganization, reclassification,
consolidation, merger, sale, dissolution, other transaction, liquidation or
winding-up shall take place, as the case may be. Such notice shall also specify
the date as of which the holders of Common Stock of record shall participate in
such dividend, distribution or subscription rights, or shall be entitled to
exchange their Common Stock for, or receive in respect of their Common Stock,
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, other transaction,
liquidation, or winding-up, as the case may be.  Such written notice shall be
given not less than five (5) Business days prior to the taking of the action in
question.

                 SECTION 8. NOTICES.  Any notice or other document required or
permitted to be given





                                       17
<PAGE>   18
or delivered to the Holder shall be delivered at, or sent by certified or
registered mail to each Holder at the address listed in the stock records of
the Company or to such other address as shall have been furnished to the
Company in writing by such Holder.  Any notice or other document required or
permitted to be given or delivered to the Company shall be delivered at, or
sent by certified or registered mail to, the principal office of the Company,
at 100 Jeffrey Avenue, Holliston, Massachusetts 01746, Attention: William
McLendon or such other name or address as shall have been furnished to the
Holder by the Company.

                 SECTION 9. LIMITATION OF LIABILITY.  No provision hereof, in
the absence of affirmative action by the Holder to purchase shares of Common
Stock, and no mere enumeration herein of the rights or privileges of the
Holder, shall give rise to any liability of the Holder for the Exercise Price
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

                 SECTION 10. GOVERNING LAW.  This Warrant shall be governed by,
and construed and enforced in accordance with, the laws of the State of
Delaware, without giving effect to its conflicts of laws provisions.

                 SECTION 11.  MISCELLANEOUS.  No term of this Warrant may be
amended, except with the joint written consent of the Holder and the Company.
The headings in this Warrant are for purposes of reference only and shall not
affect the meaning or construction of any of the provisions hereof.

Warrant to be signed by its duly authorized officer under its corporate seal,
attested by its duly authorized officer, on the date first above written.
