        (a)    In order to exercise this Warrant, in whole or in part, the
Holder hereof shall deliver to the Company, at its office set forth in Section 9

Warrant; provided, however, that this Warrant may only be partially exercised
for a minimum of 200,000 Shares per Exercise Notice. Upon receipt thereof, the
Company shall, as promptly as practicable and in any event within three (3) days
thereafter, cause to be executed and delivered to such Holder a certificate or
certificates representing the aggregate number of fully paid and nonassessable
shares of Warrant Stock, or any other property forming a part of the subject
Stock Unit(s) or both, issuable upon such exercise. Subject to the provisions of

        (b)    In addition to the method of payment set forth in Section 2(a)
and in lieu of any cash payment required thereunder, the Holder of the Warrant
shall have the right at any time and from time to time to exercise the Warrant
in whole or in part by surrendering the Warrant in the manner specified in
Section 2(a) above in exchange for that number of Shares equal to the product of
(x) the number of shares as to which such Warrant is being exercised multiplied
by (y) a fraction, the numerator of which is the market price of the Shares less
the Exercise Price and the denominator of which is such market price. Solely for
the purposes of this Section 2(b), "market price" shall be calculated on the
date on which notice of the Holder's election to exercise is given pursuant to
Section 2(a) above. The "market price" shall be the average of the closing sale
prices of the Shares as reported by Bloomberg Financial Markets or if not so
reported then as published in a nationally recognized daily publication, for the
60 consecutive trading days ending on the day prior to the date of exercise. Any
fractional share resulting from such cashless exercise shall be eliminated.

        (c)    All certificates representing Warrant Stock as aforesaid shall be
deemed to have been issued, and the Holder or other person designated to be
named therein shall be deemed to become a holder of record of the subject
Warrant Stock (including, to the extent permitted by law, the right to vote such
securities or grant consents therefor or receive notices as a stockholder), as
of the time the Holder's notice and payment is received by the Company as
aforesaid. If this Warrant shall have been exercised only in part, the Company
shall, concurrently with its delivery pursuant to Section 2(a) above, cancel
this Warrant and deliver to the subject Holder a new warrant (in substantially
the form of this Warrant) evidencing the rights of such Holder to purchase the
remaining Stock Units called for by this Warrant.

        (d)    All Warrant Stock issuable upon the exercise of this Warrant in
whole or in part shall, upon payment therefor in accordance herewith, be validly
issued, fully paid and nonassessable.

        3.     TRANSFER AND ASSIGNMENT.

        This Warrant and all rights hereunder are transferable, in whole or in
part, on the books of the Company to be maintained for such purposes, upon
surrender of this Warrant at the office of the Company set forth in Section 9
below, accompanied by a written assignment duly executed by the Holder hereof
indicating the number of Warrants being transferred and the name, address and
tax identification number of each transferee. Upon any such delivery, the
Company shall execute and deliver to the Holder or the transferee(s) or both (as
the case may be) new warrants (in substantially the form of this Warrant) in the
appropriate denominations, and this Warrant shall thereupon be canceled.

        4.     ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. In order to
prevent dilution of the rights granted under this Warrant and grant the Holder
hereof certain additional rights, the Exercise Price and the number of Shares or
any other property then constituting a Stock Unit obtainable upon exercise of
this Warrant shall be subject to adjustment from time to time as provided in
this Section 4.

        (a)    Adjustment of Exercise Price upon Issuance of Common Stock. If
and whenever on or after the Date of Issuance, the Company issues or sells, or
in accordance with Section 4(b)


                                      -3-
<PAGE>

is deemed to have issued or sold, any Share for a consideration per share less
than the Exercise Price in effect immediately prior to such issuance or sale,
then immediately upon such issuance or sale the Exercise Price shall be reduced
to a price (rounded to the nearest cent) determined by multiplying the Exercise
Price in effect immediately prior thereto by a fraction, the numerator of which
shall be (x) the sum of (A) the number of Shares outstanding immediately prior
to the issuance or sale of such additional Shares multiplied by the Exercise
Price in effect immediately prior thereto plus (B) the aggregate consideration
received by the Company (determined as provided in Section 4(b)(iv)) for the
issuance or sale of such additional Shares, and the denominator of which shall
be (y) the product of the number of shares outstanding immediately after the
issuance or sale of such additional Shares and the Exercise Price in effect
immediately prior thereto. No adjustment of the Exercise Price shall be made
upon the issuance or sale of Shares (i) pursuant to the exercise or conversion
of warrants, options or other convertible securities outstanding on the date
hereof as set forth on Schedule 4(a) attached hereto and (ii) with the unanimous
consent of the Holder(s) of the Warrant.

        (b)    Effect on Exercise Price of Certain Events. For purposes of
determining the adjusted Exercise Price under Section 4(a), the following shall
be applicable:

               (i)    Issuance of Rights or Options. If the Company in any
        manner grants or sells any options to purchase Shares or Convertible
        Securities ("OPTIONS") and the lowest price per share for which any one
        Share is issuable upon the exercise of any such Option, or upon
        conversion or exchange of any Convertible Security issuable upon
        exercise of such Option, is less than the Exercise Price in effect
        immediately prior to the time of the granting or sale of such Option,
        then such Share shall be deemed to have been issued and sold by the
        Company at such time for such price per share. For purposes of this
        paragraph, the "lowest price per share for which any one Share is
        issuable" shall be equal to the sum of the lowest amounts of
        consideration (if any) received or receivable by the Company with
        respect to any one Share upon the granting or sale of the Option, upon
        exercise of the Option and upon conversion or exchange of the
        Convertible Security. No further adjustment of the Exercise Price shall
        be made upon the actual issue of such Shares or of such Convertible
        Securities upon the exercise of such Options or upon the actual issue of
        such Shares upon conversion or exchange of such Convertible Securities.

               (ii)   Issuance of Convertible Securities. If the Company in any
        manner issues or sells any Convertible Security and the lowest price per
        share for which any one Share is issuable upon conversion or exchange
        thereof is less than the Exercise Price in effect immediately prior to
        the time of such issue or sale, then such Share or Shares shall be
        deemed to have been issued and sold by the Company at such time for such
        price per share. For the purposes of this paragraph, the "lowest price
        per share for which any one Share is issuable" shall be equal to the sum
        of the lowest amounts of consideration (if any) received or receivable
        by the Company with respect to any one Share upon the issuance of the
        Convertible Security and upon the conversion or exchange of such
        Convertible Security. No further adjustment of the Exercise Price shall
        be made upon the actual issue of such Shares upon conversion or exchange
        of any Convertible Security, and if any such issue or sale of such
        Convertible Security is made upon exercise of any Options for which
        adjustments of the Exercise Price had been or are to be made pursuant


                                      -4-
<PAGE>

        to other provisions of this Section 2, no further adjustment of the
        Exercise Price shall be made by reason of such issue or sale.

               (iii)  Change in Option Price or Conversion Rate. If the purchase
        price provided for in any Options, the additional consideration, if any,
        payable upon the issue, conversion or exchange of any Convertible
        Securities, or the rate at which any Convertible Securities are
        convertible into or exchangeable for Shares changes at any time, the
        Exercise Price in effect at the time of such change shall be adjusted
        immediately to the Exercise Price which would have been in effect at
        such time had such Options or Convertible Securities still outstanding
        provided for such changed purchase price, additional consideration or
        changed conversion rate, as the case may be, at the time initially
        granted, issued or sold and number of Shares issuable hereunder shall be
        correspondingly adjusted; provided, that if such adjustment would result
        in an increase of the Exercise Price then in effect, such adjustment
        shall not occur. For purposes of this Section 4(b), if the terms of any
        Option or Convertible Security which was outstanding as of the Date of
        Issuance are changed in the manner described in the immediately
        preceding sentence, then such Option or Convertible Security and the
        Shares deemed issuable upon exercise, conversion or exchange thereof
        shall be deemed to have been issued as of the date of such change;
        provided, that no such change shall at any time cause the Exercise Price
        hereunder to be increased.

               (iv)   Calculation of Consideration Received. If any Shares,
        Options or Convertible Securities are issued or sold or deemed to have
        been issued or sold for cash, the consideration received therefor shall
        be deemed to be the net amount received by the Company therefor. In case
        any Shares, Options or Convertible Securities are issued or sold for a
        consideration other than cash, the amount of the consideration other
        than cash received by the Company shall be the fair value of such
        consideration, except where such consideration consists of securities,
        in which case the amount of consideration received by the Company shall
        be the fair market value thereof as of the date of receipt. In case any
        Shares, Options or Convertible Securities are issued to the owners of
        the non-surviving entity in connection with any merger in which the
        Company is the surviving corporation, the amount of consideration
        therefor shall be deemed to be the fair value of such portion of the net
        assets and business of the non-surviving entity as is attributable to
        such Shares, Options or Convertible Securities, as the case may be. The
        fair value of any consideration other than cash or securities shall be
        determined jointly by the Company and the Holder of the Warrant. If such
        parties are unable to reach agreement within a reasonable period of
        time, such fair value shall be determined by an appraiser jointly
        selected by the Company and the Holder of the Warrant. The determination
        of such appraiser shall be final and binding on the Company and the
        Holder of the Warrant, and the fees and expenses of such appraiser shall
        be paid by the Company.

               (v)    Integrated Transactions. In case any Option is issued in
        connection with the issue or sale of other securities of the Company,
        together comprising one integrated transaction in which no specific
        consideration is allocated to such Options by the parties thereto, the
        Options shall be deemed to have been issued without consideration.


                                      -5-
<PAGE>

               (vi)   Treasury Shares. The disposition of any Shares owned or
        held by or for the account of the Company or any subsidiary shall be
        considered an issue or sale of Shares.

               (vii)  Record Date. If the Company takes a record of the holders
        of Shares for the purpose of entitling them (A) to receive a dividend or
        other distribution payable in Shares, Options or in Convertible
        Securities or (B) to subscribe for or purchase Shares, Options or
        Convertible Securities, then such record date shall be deemed to be the
        date of the issue or sale of the Shares deemed to have been issued or
        sold upon the declaration of such dividend or the making of such other
        distribution or the date of the granting of such right of subscription
        or purchase, as the case may be.

        (c)    Subdivision or Combination of Common Stock. If the Company at any
time subdivides (by any stock split, stock dividend, recapitalization or
otherwise) one or more classes of its outstanding Shares into a greater number
of Shares, the Exercise Price in effect immediately prior to such subdivision
shall be proportionately reduced and the number of Shares obtainable upon
exercise of this Warrant shall be proportionately increased. If the Company at
any time combines (by reverse stock split or otherwise) one or more classes of
its outstanding shares into a smaller number of Shares, the Exercise Price in
effect immediately prior to such combination shall be proportionately increased
and the number of Shares obtainable upon exercise of this Warrant shall be
proportionately decreased.

        (d)    Reorganization, Reclassification, Consolidation, Merger or Sale.
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets or other transaction,
in each case which is effected in such a way that the holders of Shares are
entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Shares is referred to
herein as "ORGANIC CHANGE." Prior to the consummation of any Organic Change, the
Company shall make appropriate provision (in form and substance satisfactory to
the Holder of the Warrant) to insure that the Holder of the Warrant shall
thereafter have the right to acquire and receive, in lieu of or addition to (as
the case may be) the Shares immediately theretofore acquirable and receivable
upon the exercise of such Holder's Warrant, such shares of stock, securities or
assets as may be issued or payable with respect to or in exchange for the number
of Shares immediately theretofore acquirable and receivable upon exercise of
such Holder's Warrant had such Organic Change not taken place. In any such case,
the Company shall make appropriate provision (in form and substance reasonably
satisfactory to the Holder of the Warrant) with respect to such Holder's rights
and interests to insure that the provisions of this Section 4 hereof shall
thereafter be applicable to the Warrant (including, in the case of any such
consolidation, merger or sale in which the successor entity or purchasing entity
is other than the Company, an immediate adjustment of the Exercise Price to the
value for the Shares reflected by the terms of such consolidation, merger or
sale, and a corresponding immediate adjustment in the number of Shares
acquirable and receivable upon exercise of the Warrant, if the value so
reflected is less than the Exercise Price in effect immediately prior to such
consolidation, merger or sale). The Company shall not effect any such
consolidation, merger or sale, unless prior to the consummation thereof, the
successor entity (if other than the Company) resulting from consolidation or
merger or the entity purchasing such assets assumes by written instrument (in
form and substance satisfactory to the Holder of the Warrant), the obligation to
deliver to each


                                      -6-
<PAGE>

such holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such holder may be entitled to acquire.

        (e)    Certain Events. If any event occurs of the type contemplated by
the provisions of this Section 4 but not expressly provided for by such
provisions (including, without limitation, the granting of stock appreciation
rights, phantom stock rights or other rights with equity features), then the
Board of Directors shall make an appropriate adjustment in the Exercise Price
and the number of Shares obtainable upon exercise of this Warrant so as to
protect the rights of the Holder of the Warrant; provided, that no such
adjustment shall increase the Exercise Price or decrease the number of Shares
obtainable as otherwise determined pursuant to this Section 4.

        (f)    Liquidating Dividends. If the Company declares or pays a dividend
upon the Shares payable otherwise than in cash out of earnings or earned surplus
(determined in accordance with generally accepted accounting principles,
consistently applied) except for a stock dividend payable in Shares (a
"LIQUIDATING DIVIDEND"), then the Company shall pay to the registered Holder of
this Warrant at the time of payment thereof the Liquidating Dividend which would
have been paid to such registered Holder on the Shares had this Warrant been
fully exercised immediately prior to the date on which a record is taken for
such Liquidating Dividend, or, if no record is taken, the date as of which the
record holders of Shares entitled to such Liquidating Dividend is to be
determined.

        (g)    Purchase Rights. If at any time the Company grants, issues or
sells any Options, Convertible Securities or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of
capital stock (the "PURCHASE RIGHTS"), then the Holder of this Warrant shall be
entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate Purchase Rights which such Holder could have acquired if such Holder
had held the number of Shares acquirable upon complete exercise of this Warrant
immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of Shares are to be determined for the grant, issue or
sale of such Purchase Rights.

        (h)    Adjustment of Number of Shares. Upon each adjustment of the
Exercise Price as a result of the calculations made in Section 4 hereof, the
number of Shares for which this Warrant is exercisable immediately prior to the
making of such adjustment shall thereafter evidence the right to purchase, at
the adjusted Exercise Price, that number of Shares obtained by (i) multiplying
the number of Shares covered by this Warrant immediately prior to this
adjustment by the Exercise Price in effect immediately prior to such adjustment
of the Exercise Price and (ii) dividing the product so obtained by the Exercise
Price in effect immediately after such adjustment of the Exercise Price.

        5.     NOTICE OF CERTAIN EVENTS.

        (a)    As soon as practicable following any adjustment of the Exercise
Price, the Company shall give written notice thereof to the Holder, setting
forth in reasonable detail and certifying the calculation of such adjustment.


                                      -7-
<PAGE>

        (b)    The Company shall give written notice to the Holder at least ten
(10) days prior to the date on which the Company closes its books or takes a
record (i) with respect to any dividend or distribution upon the Shares, (ii)
with respect to any pro rata subscription offer to holders of Shares or (iii)
for determining rights to vote with respect to any Liquidating Dividend, Organic
Change or other dissolution or liquidation; provided, however, if notice of the
foregoing is given earlier to the Company's other stockholders of record, notice
to the Holder shall be given at such earlier time.

        (c)    The Company shall also given written notice to the registered
Holder at least ten (10) days prior to the date on which any Liquidation Event,
Organic Change or other dissolution or liquidation shall take place; provided,
however, if notice of the foregoing is given earlier to the Company's other
stockholders of record, notice to the Holder shall be given at such earlier
time.

        6.     CAPITALIZATION; RESERVATION OF SHARES.

        (a)    The Company hereby represents and warrants to CRC that the number
of Shares for which this Warrant is exercisable as of the Date of Issuance, in
the aggregate, represents 10% (the "THRESHOLD PERCENTAGE") of the voting stock
of the Company on a fully-diluted as-if-converted basis (i.e., 10% of all Shares
outstanding as of the Date of Issuance and all Shares underlying options,
warrants, preferred shares or other interests outstanding as of the Date of
Issuance which are exercisable, convertible or exchangeable for Shares,
including after giving effect to the issuance of this Warrant). In the event
that such number of Shares does not equal the Threshold Percentage as a result
of the existence of any Shares (or options or other interests exercisable,
convertible or exchangeable for Shares) which are not disclosed to CRC on or
before the Date of Issuance, the number of Shares to be issued upon exercise of
this Warrant shall be automatically increased (pro rata to each Holder and
without any further action by the Holders) by that number of Shares that when
added to the Shares which would otherwise be issued to the Holders upon exercise
of the Warrant shall equal an amount of Shares which represents the Threshold
Percentage. Any such adjustment shall be made promptly upon determination of the
discrepancy with the Threshold Percentage, whether such determination is made
before or after the Date of Issuance.

        (b)    The Company shall at all times reserve and keep available for
issuance upon the exercise hereof such number of authorized but unissued Shares
as shall be sufficient to permit the full exercise of this Warrant.

        7.     EXPENSES.

        The Company shall pay any and all reasonable expenses, transfer taxes
and other charges, including all costs associated with the preparation, issuance
and delivery of stock or warrant certificates, that may be incurred in respect
of the issuance or delivery of Warrant Stock upon any exercise of this Warrant.

        8.     NO RIGHTS AS STOCKHOLDER.

        This Warrant shall not entitle the Holder to any voting rights or other
rights as a stockholder of the Company.

<PAGE>

        9.     NOTICES.

        Any and all notices to be given to the Company hereunder shall be given
to the Company at its offices located at c/o Michael A. Clark, 20 Hill Street,
Milford, CT 06460. Any and all notices to be given to the Holder hereof shall be
given to such Holder at its address as same appears on the records of the
Company.

        10.    REGISTRATION.

        (a)    Legend. Upon exercise, in part or in whole, of the Warrants,
certificates representing the Warrant Stock shall bear the following legend:

        "The securities represented by this certificate have not been registered
        under the Securities Act of 1933, as amended ("Act"), and may not be
        offered or sold except pursuant to (i) an effective registration
        statement under the Act, (ii) to the extent applicable, Rule 144 under
        the Act (or any similar rule under such Act relating to the disposition
