         3.       Duration, Exercise of Warrants and Redemption.
                  ---------------------------------------------

                  (a)       This Warrant shall be exercisable by the registered
Holder on any business day before 5:30 P.M., Boston time, at any time and from
time to time on or after March 21, 2002 to and including the Expiration Date.
At 5:30 P.M., Boston time on the Expiration Date, the portion of this Warrant
not exercised prior thereto shall be and become void and of no value.

                  (b)       Upon surrender of this Warrant, with the Form of
Election to Purchase attached hereto as Exhibit B duly completed and signed, to
                                        ---------
the Company at its office at 150 Dan Road, Canton, Massachusetts 02021,
Attention: Chief Financial Officer, or at such other address as the Company may

by certified or official bank check or checks or wire transfer, all as
specified by the Holder in the Form of Election to Purchase attached hereto as
Exhibit B, the Company shall promptly (but in no event later than three (3)
---------
business days after the Date of Exercise (as defined herein), issue or cause to
be issued and cause to be delivered to or upon the written order of the Holder
and in such name or names as the Holder may designate, a certificate for the
Warrant Shares issuable upon such exercise, free of restrictive legends other
than as required by Section 12 hereof and any legends placed on all shares of
Common Stock of the Company relating to the then current agreement between the
Company and its transfer agent relating to the issuance of "rights" to all
holders of shares of the Company's Common Stock. Any person so designated by
the Holder to receive Warrant Shares shall be deemed to have become holder of
record of such Warrant Shares as of the Date of Exercise of this Warrant.

                                      2

<PAGE>

                  A "Date of Exercise" means the date on which the Company
                     ----------------
shall have received (i) this Warrant (or any New Warrant, as applicable), with
the Form of Election to Purchase attached hereto as Exhibit B (or attached to
                                                    ---------
such New Warrant) appropriately completed and duly signed, and (ii) payment of
the Exercise Price for the number of Warrant Shares so indicated by the Holder
hereof to be purchased.

                  (c)      If by the fourth (4th) business day after a Date of
Exercise the Company fails to deliver the required number of Warrant Shares in
the manner required pursuant to Section 3(b), then the Holder will have the
right to rescind such exercise.

                  (d)      If by the fourth (4th) business day after a Date of
Exercise the Holder has not rescinded the exercise pursuant to Section 3(c) and
the Company has not delivered the required number of Warrant Shares in the
manner required pursuant to Section 3(b), then if after such fourth (4th)
business day the Holder purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by the Holder of the
Warrant Shares which the Holder anticipated receiving upon such exercise (a
"Buy-In"), then the Company shall (1) pay in cash to the Holder the amount by
which (x) the Holder's total purchase price (including customary brokerage
commissions, if any) for the shares of Common Stock so purchased exceeds (y) the
amount obtained by multiplying (A) the number of Warrant Shares that the Company
was required to deliver to the Holder in connection with the exercise at issue
by (B) the Closing Price of the Common Stock at the time of the obligation
giving rise to such purchase obligation and (2) at the option of the Holder,
either reinstate the portion of the Warrant representing the equivalent number
of Warrant Shares for which such exercise was not honored or deliver to the
Holder the number of shares of Common Stock that would have been issued had the
Company timely complied with its exercise and delivery obligations hereunder.
For example, if the Holder purchases Common Stock having a total purchase price
of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of
Common Stock with a market price on the date of exercise totaled $10,000, under
clause (1) of the immediately preceding sentence the Company shall be required
to pay the Holder $1,000. The Holder shall provide written notice to the
Company, which notice shall include such supporting documentation as reasonably
necessary to indicate and substantiate the amounts payable to the Holder in
respect of the Buy-In.

                  (e)      This Warrant shall be exercisable, either in its
entirety or, from time to time, for a portion of the number of Warrant Shares.
If less than all of the Warrant Shares which may be purchased under this
Warrant are exercised at any time, the Company shall issue or cause to be
issued, at its expense, a New Warrant evidencing the right to purchase the
remaining number of Warrant Shares for which no exercise has been evidenced by
this Warrant.

                  (f)      Right to Convert Warrant into Stock: Net Issuance.
                           -------------------------------------------------
The Holder shall be entitled to convert this Warrant on a "cashless" basis into
shares of Common Stock in accordance with the provisions of this Section 3(f).

                           (i)     Right to Convert. In addition to and without
                                   ----------------
                  limiting the rights of the Holder under the terms of this
                  Warrant, the Holder shall have the right to convert this
                  Warrant or any portion hereof (the "Conversion Right") into
                                                      ----------------
                  shares

                                      3

<PAGE>

                  of Common Stock as provided in this Section 3(f) at any time
                  or from time to time during the term of this Warrant. Upon
                  exercise of the Conversion Right with respect to a
                  particular number of shares subject to this Warrant (the
                  "Converted Warrant Shares"), the Company shall deliver to
                   --------- --------------
                  the Holder (without payment by the Holder of any Exercise
                  Price or any cash or other consideration, except as may be
                  required under Section 6 hereof) that number of shares of
                  fully paid and nonassessable Common Stock equal to the
                  quotient obtained by dividing (X) the value of this Warrant
                  (or the specified portion hereof) on the Conversion Date (as
                  defined below), which value shall be determined by
                  subtracting (A) the aggregate Exercise Price of the
                  Converted Warrant Shares immediately prior to the exercise
                  of the Conversion Right from (B) the aggregate fair market
                  value of the Converted Warrant Shares issuable upon exercise
                  of this Warrant (or the specified portion hereof) on the
                  Conversion Date (as herein defined) by (Y) the fair market
                  value of one share of Common Stock on the Conversion Date
                  (as herein defined).

                  Expressed as a formula, such conversion shall be computed as
                  follows:

                  X        =         B-A
                                     ---
                                      Y

         Where:                      X = the number of shares of Common Stock
that may be issued to Holder

                           Y = the fair market value (FMV) of one share of
                               Common Stock

                           A = the aggregate Exercise Price (Number of Converted
                               Warrant Shares x Exercise Price)

                           B = the aggregate FMV (i.e., FMV x Number of
                               Converted Warrant Shares)

                  No fractional shares shall be issuable upon exercise of the
                  Conversion Right, and, if the number of shares to be issued as
                  determined in accordance with the foregoing formula is other
                  than a whole number, the Company shall either pay to the
                  Holder an amount in cash determined in accordance with Section
                  10 or round the number of Converted Warrant Shares as provided
                  in Section 10.

                           (ii)    Method of Exercise. The Conversion Right may
                                   ------------------
                  be exercised by the Holder by the surrender of this Warrant at
                  the principal office of the Company together with the Form of
                  Election to Purchase attached hereto as Exhibit B, duly
                                                          ---------
                  completed and executed and indicating the number of shares
                  subject to this Warrant which are being surrendered (referred
                  to in Section 3(f) hereof as the Converted Warrant Shares) in
                  exercise of the Conversion Right. Such conversion shall be
                  effective upon receipt by the Company of this Warrant together
                  with the aforesaid Form of Election to Purchase (the
                  "Conversion Date"). Certificates for
                   ---------------

<PAGE>

                  the shares issuable upon exercise of the Conversion Right
                  and, if applicable, a new Warrant evidencing the balance of
                  the shares remaining subject to this Warrant, shall be
                  issued as of the Conversion Date and shall be delivered to
                  the Holder within three (3) business days following the
                  Conversion Date.

                           (iii)   Determination of Fair Market Value. For
                                   ----------------------------------
                  purposes of this Section 3(f), "fair market value" of a share
                                                  -----------------
                  of Common Stock as of a particular date (the "Determination
                                                                -------------
                  Date") shall mean as follows:
                  ----

                                   (A)     If traded on a securities exchange,
                           the fair market value of the Common Stock shall be
                           deemed to be the average of the closing prices of
                           the Common Stock on such exchange over the five-day
                           period ending one business day prior to the
                           Determination Date or, if less, such number of days
                           as the Common Stock has been traded on such
                           exchange; or

                                   (B)     If traded over-the-counter, the fair
                           market value of the Common Stock shall be deemed to
                           be the average of the closing bid prices of the
                           Common Stock over the five-day period ending one
                           business day prior to the Determination Date or, if
                           less, such number of days as the Common Stock has
                           been traded over-the-counter; or

                                   (C)     If there is no public market for the
                           Common Stock, then fair market value shall be
                           determined in good faith by the Board of Directors of
                           the Company.

                           (iv)    For purposes of Rule 144 promulgated under

                  the Securities Act, it is intended, understood and
                  acknowledged that the Warrant Shares issued in a "cashless"
                  exercise transaction shall be deemed to have been acquired
                  by the Holder, and the holding period for the Warrant Shares
                  shall be deemed to have commenced, on the date this Warrant
                  was originally issued pursuant to the Stock Purchase
                  Agreement.

         4.       Limitations on Exercise. In no event shall the Holder hereof
                  -----------------------
have the right to exercise any portion of this Warrant for shares of Common
Stock or to dispose of any portion of this Warrant to the extent that such
right to effect such exercise or disposition would result in the Holder or any
of its affiliates beneficially owning more than 4.99% of the outstanding shares
of Common Stock. For purposes of this Section 4, beneficial ownership shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended, and Regulation 13D-G thereunder. The restriction contained in
this Section 4 may not be altered, amended, deleted or changed in any manner
whatsoever unless the holders of a majority of the outstanding shares of Common
Stock and the Holder hereof shall approve, in writing, such alteration,
amendment, deletion or change. Notwithstanding the foregoing, the Holder hereof
may, by providing written notice to the Company, adjust the restriction set
forth in this Section 4 so that the limitation on beneficial ownership of 4.99%
of the outstanding shares of Common Stock referred to above shall be increased
to 9.99%, which adjustment shall not take effect until

                                      5

<PAGE>

the 61/st/ day after the date of such notice. This provision shall not restrict
the number of shares of Common Stock which a Holder may receive or beneficially
own in order to determine the amount of securities or other consideration that
such Holder may receive in the event of a merger, sale or other business
combination or reclassification involving the Company as contemplated herein.

         5.       Registration Rights. This Warrant and the Warrant Shares are
                  -------------------
subject to the registration rights provided in Section 8 of that certain Stock
Purchase Agreement, dated as of March 13, 2002, by and between the Company and
the Investor (as defined in such Stock Purchase Agreement)..

         6.       Payment of Taxes. The Company will pay all documentary stamp
                  ----------------
taxes attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the
registration of this Warrant or any certificates for Warrant Shares issuable
upon the exercise of this Warrant in a name other than that of the Holder, and
the Company shall not be required to issue or cause to be issued or deliver or
cause to be delivered the certificates for Warrant Shares unless or until the
person or persons requesting the issuance thereof shall have paid to the
Company the amount of such tax or shall have established to the satisfaction of
the Company that such tax has been paid. The Holder shall be responsible for
all other tax liability that may arise as a result of holding or transferring
this Warrant or receiving Warrant Shares upon exercise hereof.

         7.       Replacement of Warrant. If this Warrant is mutilated, lost,
                  ----------------------
stolen or destroyed, the Company may, in its discretion, issue or cause to be
issued in exchange and substitution for and upon cancellation hereof, or in
lieu of and substitution for this Warrant, a New Warrant, but only upon receipt
of evidence reasonably satisfactory to the Company of such loss, theft or
destruction and indemnity, if reasonably satisfactory to it. Applicants for a
New Warrant under such circumstances shall also comply with such other
reasonable regulations and procedures and pay such other reasonable charges as
the Company may prescribe.

         8.       Reservation of Warrant Shares. The Company covenants that it
                  -----------------------------
will at all times reserve and keep available out of its authorized and unissued
shares of Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holders (taking into account the adjustments
and restrictions set forth in Section 9 hereof). The Company covenants that all
Warrant Shares that shall be so issuable and deliverable shall, upon issuance
and the payment of the applicable Exercise Price in accordance with the terms
hereof, be duly and validly authorized, issued and fully paid and
nonassessable. The Company shall use its best efforts to provide for and
maintain the listing of the Common Stock of the Company, including the Warrant
Shares, upon the American Stock Exchange (or any other securities exchange or
automated quotation system which is the principal exchange or system on which
the Common Stock is then traded or listed).

         9.       Certain Adjustments. The Exercise Price and number of Warrant
                  -------------------
Shares issuable upon exercise of this Warrant are subject to adjustment from
time to time as set forth in this Section 9. Upon each such adjustment of the
Exercise Price pursuant to this Section 9, the Holder shall thereafter prior to
the Expiration Date be entitled to purchase, at the Exercise Price resulting
from such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

                  (a)      If the Company, at any time while this Warrant is
outstanding, (i) shall pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock, (ii) subdivide outstanding shares
of Common Stock into a larger number of shares, or (iii) combine outstanding
shares of Common Stock into a smaller number of shares, the Exercise Price shall
be multiplied by a fraction of which the numerator shall be the number of shares
of Common Stock (excluding treasury shares, if any) outstanding before such
event and of which the denominator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding after such event. Any adjustment
made pursuant to this Section 9 shall become effective immediately after the
record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination, and shall apply to
successive subdivisions and combinations.

                  (b)      In case of any reclassification or change of the
shares of Common Stock of the Company issuable upon exercise of this Warrant
(other than a change in par value, or as a result of a subdivision or
combination covered by Section 9(a) above, but including any change in the
shares of Common Stock of the Company into one or more classes or series of
shares), or in case of any consolidation or merger of another corporation into
the Company in which the Company is the continuing corporation and in which
there is a reclassification or change (including a change to the right to
receive shares of stock (other than Common Stock), other securities, property
or cash) of the shares of Common Stock of the Company (other than a change in
par value, or as a result of a subdivision or combination covered by Section
9(a) above, but including any change in the shares into one or more classes or
series of shares), then the Holder shall have the right thereafter to exercise
this Warrant only into the shares of stock and other securities of the Company
and property receivable or deemed to be held by holders of shares of Common
Stock of the Company following such reclassification, change, consolidation, or
merger, and the Holder shall thereafter upon exercise of this Warrant be
entitled to receive such amount of securities or property attributable to the
number of Warrant Shares such Holder would have been entitled to receive had
such Holder exercised this Warrant immediately prior to such action. The terms
of any such reclassification or other action shall include such terms so as to
continue to give to the Holder the right to receive the securities or property
set forth in this Section 9(b) upon any exercise following any such
reclassification or other action.

                  (c)      In case of any consolidation of the Company with, or
merger of the Company with or into, another corporation (other than a merger or
consolidation in which the Company is the surviving or continuing corporation),
such successor shall (i) execute and deliver

                                      7

<PAGE>

to the Holder an agreement providing that the Holder shall have the right
thereafter to receive upon exercise of this Warrant solely the kind and amount
of shares of stock and other securities, property, cash or any combination
thereof receivable upon such consolidation or merger by a holder of the number
of shares of Common Stock of the Company for which this Warrant might have been
exercised immediately prior to such consolidation, merger, sale, lease or
conveyance, and (ii) make effective provision in its certificate of
incorporation or otherwise, if necessary, to effect such agreement. Such
agreement shall provide for adjustments which shall be as nearly equivalent as
practicable to the adjustments in this Section 9.

                  (d)      If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of shares of Common Stock of the
Company (and not to holders of this Warrant) evidences of its indebtedness or
assets or rights or warrants to subscribe for or purchase any security
(excluding those referred to in Sections 9(a), (b) and (e) hereof), then in each
such case the Exercise Price shall be determined by multiplying the Exercise
Price in effect immediately prior to the record date fixed for determination of
stockholders entitled to receive such distribution by a fraction of which the
denominator shall be the Exercise Price determined as of the record date
mentioned above, and of which the numerator shall be such Exercise Price on such
record date less the then fair market value at such record date of the portion
of such assets or evidence of indebtedness so distributed applicable to one
outstanding share of Common Stock of the Company as determined by a nationally
recognized or major regional investment banking firm or firm of independent
certified public accountants of recognized standing (which may be the firm that
regularly examines the financial statements of the Company) (an "Appraiser")
                                                                 ---------
mutually selected in good faith by the holders of a majority in interest of the
Warrants then outstanding and the Company. Any determination made by the
Appraiser shall be final and binding upon the Company and the Holder.

                  (e)      If, at any time while this Warrant is outstanding,
the Company shall issue or cause to be issued rights or warrants to acquire or
otherwise sell or distribute shares of Common Stock of the Company to all
holders of shares of its Common Stock for a consideration per share less than
the Exercise Price then in effect, then, promptly upon such issue or sale, the
Exercise Price shall be reduced to the price (calculated to the nearest cent)
determined by dividing (i) an amount equal to the sum of (A) the number of
shares of Common Stock of the Company outstanding immediately prior to such
issue or sale multiplied by the Exercise Price, and (B) the consideration, if
any, received or receivable by the Company upon such issue or sale by (ii) the
total number of shares of Common Stock of the Company outstanding immediately
after such issue or sale.

                  (f)      For the purposes of this Section 9, the following
clauses shall also be applicable:

                           (i)     Record Date. In case the Company shall take
                                   -----------
a record of the holders of its Common Stock for the purpose of entitling them
(A) to receive a dividend or other distribution payable in shares of Common
Stock of the Company or in securities convertible or exchangeable into shares
of Common Stock of the Company, or (B) to subscribe for or purchase shares of
Common Stock of the Company or securities convertible or exchangeable into
shares of

                                      8

<PAGE>

its Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock of the Company 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.

                           (ii)    Treasury Shares. The number of shares of
                                   ---------------
Common Stock of the Company outstanding at any given time shall not include
shares owned or held by or for the account of the Company, and the disposition
of any such shares shall be considered an issue or sale of Common Stock.

                  (g)      All calculations under this Section 9 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be.

                  (i)      If:

                                   (i)     the Company shall declare a dividend
                                           (or any other distribution) on its
                                           Common Stock; or

                                   (ii)    the Company shall declare a special
                                           non-recurring cash dividend on its
                                           Common Stock; or

                                   (iii)   the Company shall authorize the
                                           granting to all holders of shares of
                                           Common Stock of the Company rights
                                           or warrants to subscribe for or
                                           purchase any shares of capital stock
                                           of any class or of any rights; or

                                   (iv)    the approval of any stockholders of
                                           the Company shall be required in
                                           connection with any reclassification
                                           or change of the shares of Common
                                           Stock of the Company issuable upon
                                           exercise of this Warrant (other than
                                           a change in par value, or as a
                                           result of a subdivision or
                                           combination, but including any
                                           change in the shares into one or
                                           more classes or series of shares),
                                           or any consolidation or merger of
                                           another corporation with the
                                           Company; or

                                   (v)     the Company shall authorize the
                                           voluntary dissolution, liquidation or
                                           winding up of the affairs of the
                                           Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least thirty (30) calendar
days prior to the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution, redemption, rights or warrants, or if a record is
not to be taken, the date as of which the holders of record of shares of Common
Stock of the Company to be entitled to such dividend, distributions, redemption,
rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or

                                      9

<PAGE>

share exchange is expected to become effective or close, and the date as of
which it is expected that holders of record of shares of Common Stock of the
Company shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
               --------  -------
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

         10.      Fractional Shares. The Company shall not be required to issue
                  -----------------
or cause to be issued fractional Warrant Shares on the exercise of this
Warrant. The number of full Warrant Shares which shall be issuable upon the
exercise of this Warrant shall be computed on the basis of the aggregate number
of Warrant Shares purchasable on exercise of this Warrant so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section
10, be issuable on the exercise of this Warrant, the Company shall, at its
option, (i) pay an amount in cash equal to the Exercise Price multiplied by
such fraction or (ii) round the number of Warrant Shares issuable up to the
next whole number.

         11.      Investment Representations. The Holder represents to the
                  --------------------------
Company that this Warrant is being acquired for the Holder's own account and
for the purpose of investment and not with a view to, or for sale in connection
with, the distribution thereof, nor with any present intention of distributing
or selling this Warrant or the Warrant Shares. The Holder acknowledges that it
has been afforded the opportunity to meet with the management of the Company
and to ask questions of, and receive answers from, such management and the
Company's counsel about the business and affairs of the Company and concerning
the terms and conditions of the offering of this Warrant, and to obtain any
additional information, to the extent that the Company possessed such
information or could acquire it without unreasonable effort or expense,
necessary to verify the accuracy of the information otherwise obtained by or
furnished to the Holder. The Holder has received all information which the
Holder considered necessary to form a decision concerning the purchase of this
Warrant, and no valid request to the Company by the Holder hereof for
information of any kind about the Company has been refused or denied by the
Company or remains unfulfilled as of the date hereof. The Holder asserts that
it may be considered to be a sophisticated investor, has such knowledge and
experience in financial business matters that it is capable of evaluating the
merits and risk of the investment in this Warrant and the Warrant Shares, and
is able to bear the economic risk of the investment. The Holder represents and
warrants that it is an accredited investor, as that term is defined in
Regulation D under the Securities Act.

         12.      Legend. Until no longer required under applicable securities
                  ------
laws, any certificate evidencing the Warrant Shares will bear a legend
indicating that such Warrant Shares have not been registered under the
Securities Act. The holder hereof, by purchasing this security, agrees for the
benefit of the Company that this security may be resold, pledged or otherwise
transferred only (a) to the Company, (b) if the Company shall have received an
opinion of counsel satisfactory to the Company that an exemption from
registration under the Securities Act is available, or (c) pursuant to an
effective registration statement under the Securities Act, in each case in
accordance with any applicable securities laws of any state of the United
States.

         14.      Warrant Agent.
                  -------------

                  (a)      The Company shall serve as warrant agent under this
Warrant. Upon thirty (30) days' notice to the Holder, the Company may appoint a
new warrant agent.

                  (b)      Any corporation into which the Company or any new
warrant agent may be merged or any corporation resulting from any consolidation
to which the Company or any new warrant agent shall be a party or any
corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business
shall be a successor warrant agent under this Warrant without any further act.
Any such successor warrant agent shall promptly cause notice of its succession
as warrant agent to be mailed (by first class mail, postage prepaid) to the
Holder at the Holder's last address as shown on the Warrant Register.

         15.      Miscellaneous.
                  -------------

                  (a)      This Warrant shall be binding on and inure to the
benefit of the parties hereto and their respective successors and permitted
assigns. This Warrant may be amended only in writing signed by the Company and

                  (b)      Subject to Section 15(a), above, nothing in this
Warrant shall be construed to give to any person or corporation other than the
Company and the Holder any legal or equitable right, remedy or cause under this
Warrant; this Warrant shall be for the sole and exclusive benefit of the
Company and the Holder.

                  (c)      This Warrant shall be governed by and construed and
enforced in accordance with the internal laws of the State of Delaware without
regard to the principles of conflicts of law thereof.

                  (d)      The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

                  (e)      In case any one or more of the provisions of this
Warrant shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
in any way be affected or impaired thereby and the parties will attempt in good
faith to agree upon a valid and enforceable provision which shall be a
commercially reasonable substitute therefor, and upon so agreeing, shall
incorporate such substitute provision in this Warrant.

                  (f)      Nothing contained in this Warrant shall be construed
as conferring upon the Holder hereof the right to vote or to consent as
stockholders in respect of the meetings of stockholders of the Company or the
election of members of the Board of Directors of the Company or any other
matter, or any rights whatsoever as stockholders of the Company or as imposing
any obligation on such Holder to purchase any securities or as imposing any
liabilities on such Holder as a stockholder of the Company, whether such
obligation or liabilities are asserted by the Company or by creditors of the
Company. Notwithstanding the foregoing, the Company will furnish to each Holder
of any Warrants, promptly upon their becoming available, copies of all
financial statements, reports, notices and proxy statements sent or made
