         2. EXERCISE OF WARRANT.

         This Warrant may be exercised by the Warrant Holder, in whole or in
part, at any time and from time to time by either of the following methods:

         (a) The Warrant Holder may surrender this Warrant, together with the
form of subscription at the end hereof duly executed by such Warrant Holder
("SUBSCRIPTION NOTICE"), at the offices of the Company or any transfer agent for
the Common Stock; together with payment of the aggregate Purchase Price for all
Warrant Shares exercised; or

         (b) The Warrant Holder may also exercise this Warrant, in whole or in
part, in a "cashless" or "net-issue" exercise by delivering to the offices of
the Company or any transfer agent for the Common Stock this Warrant, together
with a Subscription Notice specifying the number of Warrant Shares to be
delivered to such Warrant Holder ("DELIVERABLE SHARES") and the number of
Warrant Shares with respect to which this Warrant is being surrendered in
payment of the aggregate Purchase Price for the Deliverable Shares ("SURRENDERED
SHARES"); provided that the Purchase Price multiplied by the number of
Deliverable Shares shall not exceed the value of the Surrendered Shares; and
provided further that the sum of the number of Deliverable Shares and the number
of Surrendered Shares so specified shall not exceed the aggregate number of
Warrant Shares represented by this Warrant. For the purposes of this provision,
each Warrant Share as to which this Warrant is surrendered will be attributed a
value equal to the fair market value (as defined below) of the Warrant Share
minus the Purchase Price of the Warrant Share (the "Spread"). The number of
Deliverable Shares shall be equal to (i) the number of Surrendered Shares
multiplied by the Spread; divided by (ii) the fair market value of the Common
Stock on the date of exercise.

         In the event that the Warrant is not exercised in full, the number of
Warrant Shares shall be reduced by the number of such Warrant Shares for which
this Warrant is exercised and/or surrendered, and the Company, at its expense,
shall within three (3) Trading Days (as defined below) issue and deliver or upon
the order of Warrant Holder a new Warrant of like tenor in the name of Warrant
Holder or as Warrant Holder (upon payment by Warrant Holder of any applicable
transfer taxes) may request, reflecting such adjusted Warrant Shares.


                                         2

<PAGE>

         3. DELIVERY OF STOCK CERTIFICATES.

                  (a) Subject to the terms and conditions of this Warrant, as
soon as practicable after the exercise of this Warrant in full or in part, and
in any event within three (3) Trading Days thereafter, the Company shall
transmit the certificates (together with any other stock or other securities or
property to which Warrant Holder is entitled upon exercise) by messenger or
overnight delivery service to reach the address designated by such holder within
three (3) Trading Days after the receipt of the Subscription Notice ("T+3"). If
such certificates are not received by the Warrant Holder within T+3, then the
Warrant Holder will be entitled to revoke and withdraw its exercise of its
Warrant at any time prior to its receipt of those certificates.

                           In lieu of delivering physical certificates
representing the Warrant Shares deliverable upon exercise of Warrants, provided
the Company's transfer agent is participating in the Depository Trust Company
("DTC") Fast Automated Securities Transfer ("FAST") program, upon request of the
Warrant Holder, the Company shall use its best efforts to cause its transfer
agent to electronically transmit the Warrant Shares issuable upon exercise to
the Warrant Holder, by crediting the account of Warrant Holder's prime broker
with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system. The
time periods for delivery described above shall apply to the electronic
transmittals through the DWAC system. The parties agree to coordinate with DTC
to accomplish this objective. The exchange pursuant to Section 3 shall be deemed
to have been made immediately prior to the close of business on the date of the
Subscription Notice. The person or persons entitled to receive the Warrant
Shares issuable upon such exercise shall be treated for all purposes as the
record holder or holders of such Common Shares at the close of business on the
date of the Subscription Notice.

                           The term "TRADING DAY" means (x) if the Common Stock
is listed on the New York Stock Exchange or the American Stock Exchange, a day
on which there is trading on such stock exchange, (y) if the Common Stock is not
listed on either of such stock exchanges but sale prices of the Common Stock are
reported on an automated quotation system, a day on which trading is reported on
the principal automated quotation system on which sales of the Common Stock are
reported, or (z) if the foregoing provisions are inapplicable, a day on which
quotations are reported by National Quotation Bureau Incorporated.

                  (b) This Warrant may not be exercised as to fractional shares
of Common Stock. In the event that the exercise of this Warrant, in full or in
part, would result in the issuance of any fractional share of Common Stock, then
in such event the Warrant Holder shall be entitled to cash equal to the fair
market value of such fractional share. For purposes of this Warrant, "fair
market value" shall equal the closing trading price of the Common Stock on the
Approved Market which is the principal trading exchange or market for the Common
Stock (the "Principal Market") on the date of determination or, if the Common
Stock is not listed or admitted to trading on any Approved Market, the average
of the closing bid and asked prices on the over-the-counter market as furnished
by any New York Stock Exchange member firm reasonably selected from time to time
by the Company for that purpose and reasonably acceptable to the Warrant Holder,
or, if the Common Stock is not listed or admitted to trading on any Approved
Market or traded over-the-counter and the average price cannot be determined as
contemplated above, the fair-market value of the Common Stock shall be as
reasonably determined in good faith by the Company's Board of


                                         3

<PAGE>

Directors with the concurrence of the Warrant Holder.

         4. REPURCHASE OF WARRANT SHARES AT THE OPTION OF THE COMPANY. At any
time and from time to time, from the date hereof until all Warrant Shares
represented by this Warrant have been exercised, provided that the Company at
such time is not in breach of the provisions of this Warrant, the Registration
Rights Agreement and the Investment Agreement, and that there is Effective
Registration, the Company may purchase from the Holder the Warrant at a purchase
price per share equal to (i) $35.00 times (ii) a number equal to the number of
Warrant Shares remaining exercisable pursuant to the Warrant, subject to
adjustments provided in Section 6 hereof (the "Repurchase Price"). Any such
repurchase by the Company shall be preceded by a "Notice of Repurchase" sent by
the Company to the Holder of the Warrant Shares to be repurchased. The
Repurchase Price shall be paid by the Company to the Holder, or such Holder's
designee, in cash 30 days following the receipt by the Holder of the Notice of
Repurchase. Until such 30th day following receipt of the Notice of Repurchase,
the Holder's right to exercise this Warrant pursuant to Section 2 hereof shall
remain unaffected.

         5. (A) REPRESENTATIONS AND COVENANTS OF THE COMPANY.

                  (a) The Company shall comply with its obligations under the
Registration Rights Agreement with respect to the Warrant Shares, including,
without limitation, the Company's obligation to have filed and declared and
maintained effective a registration statement registering the Warrant Shares
under the Securities Act of 1933, as amended (the "ACT").

                  (b) The Company shall take all necessary action and
proceedings as may be required and permitted by applicable law, rule and
regulation, including, without limitation, the notification of the Principal
Market, for the legal and valid issuance of this Warrant and the Warrant Shares
to the Warrant Holder under this Warrant.

                  (c) From the date hereof through the last date on which this
Warrant is exercisable, the Company shall take all steps necessary to insure
that the Common Stock remains listed on the Principal Market.

                  (d) The Warrant Shares, when issued in accordance with the
terms hereof, will be duly authorized and, when paid for or issued in accordance
with the terms hereof, shall be validly issued, fully paid and non-assessable.
The Company has authorized and reserved for issuance to Warrant Holder the
requisite number of shares of Common Stock to be issued pursuant to this
Warrant.

                  (e) The Company shall at all times reserve and keep available,
solely for issuance and delivery as Warrant Shares hereunder, 150% of such
number of shares of Common Stock as shall from time to time be issuable
hereunder.

                  (f) With a view to making available to the Warrant Holder the
benefits of Rule 144 promulgated under the Act and any other rule or regulation
of the Securities and Exchange Commission ("SEC") that may at any time permit
Warrant Holder to sell securities of

                                        4

<PAGE>

the Company to the public without registration, the Company agrees to use its
best efforts to:

                           i) make and keep public information available, as
                  those terms are understood and defined in Rule 144, at all
                  times;

                           ii) file with the SEC in a timely manner all reports
                  and other documents required of the Company under the Act and
                  the Securities Exchange Act of 1934, as amended (the "EXCHANGE
                  ACT"); and

                           iii) furnish to any Warrant Holder forthwith upon
                  request a written statement by the Company that it has
                  complied with the reporting requirements of Rule 144 and of
                  the Act and the Exchange Act, a copy of the most recent annual
                  or quarterly report of the Company, and such other reports and
                  documents so filed by the Company as may be reasonably
                  requested to permit any such Warrant Holder to take advantage
                  of any rule or regulation of the SEC permitting the selling of
                  any such securities without registration.

                  (B) REPRESENTATIONS AND COVENANTS OF THE PURCHASER.

         The Purchaser shall not resell Warrant Shares, unless such resale is
pursuant to an effective registration statement under the Act or pursuant to an
applicable exemption from such registration requirements.

         6. ADJUSTMENT OF PURCHASE PRICE AND REPURCHASE PRICE AND NUMBER OF
SHARES. The number of and kind of securities purchasable upon exercise of this
Warrant and the Purchase Price and the Repurchase Price shall be subject to
adjustment from time to time as follows:

                  (a) SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES. If the
Company shall at any time after the date hereof but prior to the expiration of
this Warrant subdivide its outstanding securities as to which purchase rights
under this Warrant exist, by split-up, spin-off, or otherwise, or combine its
outstanding securities as to which purchase rights under this Warrant exist, the
number of Warrant Shares as to which this Warrant is exercisable as of the date
of such subdivision, split-up, spin-off or combination shall forthwith be
proportionately increased in the case of a subdivision, or proportionately
decreased in the case of a combination. Appropriate proportional adjustments
(decrease in the case of subdivision, increase in the case of combination) shall
also be made to the Purchase Price and Repurchase Price payable per share, so
that the aggregate Purchase Price or Repurchase Price payable for the total
number of Warrant Shares or Warrants purchasable under this Warrant as of such
date shall remain the same as it would have been before such subdivision or
combination.

                  (b) STOCK DIVIDEND. If at any time after the date hereof the
Company declares a dividend or other distribution on Common Stock payable in
Common Stock or other securities or rights convertible into or exchangeable for
Common Stock ("COMMON STOCK EQUIVALENTS") without payment of any consideration
by holders of Common Stock for the additional shares of Common Stock or the
Common Stock Equivalents (including the additional shares of Common

                                       5

<PAGE>

Stock issuable upon exercise or conversion thereof), then the number of shares
of Common Stock for which this Warrant may be exercised shall be increased as of
the record date (or the date of such dividend distribution if no record date is
set) for determining which holders of Common Stock shall be entitled to receive
such dividends, in proportion to the increase in the number of outstanding
shares (and shares of Common Stock issuable upon conversion of all such
securities convertible into Common Stock) of Common Stock as a result of such
dividend, and the Purchase Price and the Repurchase Price shall be
proportionately reduced so that the aggregate Purchase Price and Repurchase
Price for all the Warrant Shares issuable hereunder immediately after the record
date (or on the date of such distribution, if applicable), for such dividend
shall equal the aggregate Purchase Price or Repurchase Price so payable
immediately before such record date (or on the date of such distribution, if
applicable).

                  (c) OTHER DISTRIBUTIONS. If at any time after the date hereof
the Company distributes to holders of its Common Stock, other than as part of
its dissolution, liquidation or the winding up of its affairs, any shares of its
capital stock, any evidence of indebtedness or any of its assets (other than
Common Stock), then the number of Warrant Shares for which this Warrant is
exercisable shall be increased to equal: (i) the number of Warrant Shares for
which this Warrant is exercisable immediately prior to such event, (ii)
multiplied by a fraction, (A) the numerator of which shall be the fair market
value per share of Common Stock on the record date for the dividend or
distribution, and (B) the denominator of which shall be the fair market value
price per share of Common Stock on the record date for the dividend or
distribution minus the amount allocable to one share of Common Stock of the
value (as jointly determined in good faith by the Board of Directors of the
Company and the Warrant Holder) of any and all such evidences of indebtedness,
shares of capital stock, other securities or property, so distributed. The
Purchase Price shall be reduced to equal: (i) the Purchase Price in effect
immediately before the occurrence of any event (ii) multiplied by a fraction,
(A) the numerator of which is the number of Warrant Shares for which this
Warrant is exercisable immediately before the adjustment, and (B) the
denominator of which is the number of Warrant Shares for which this Warrant is
exercisable immediately after the adjustment. The Repurchase Price shall be
reduced to equal: (i) $35.00 (ii) multiplied by a fraction, (A) the numerator of
which is the number of Warrant Shares for which this Warrant is exercisable
immediately before the adjustment, and (B) the denominator of which is the
number of Warrant Shares for which this Warrant is exercisable immediately after
the adjustment.

                  (d) MERGER, ETC. If at any time after the date hereof there
shall be a merger or consolidation of the Company with or into or a transfer of
all or substantially all of the assets of the Company to another entity, then
the Warrant Holder shall be entitled to receive upon or after such transfer,
merger or consolidation becoming effective, and upon payment of the Purchase
Price then in effect, the number of shares or other securities or property of
the Company or of the successor corporation resulting from such merger or
consolidation, which would have been received by Warrant Holder for the shares
of stock subject to this Warrant had this Warrant been exercised just prior to
such transfer, merger or consolidation becoming effective or to the applicable
record date thereof, as the case may be. The Company will not merge or
consolidate with or into any other corporation, or sell or otherwise transfer
its property, assets and business substantially as an entirety to another
corporation, unless the corporation resulting from such merger or consolidation
(if not the Company), or such transferee corporation, as the case may be, shall
expressly assume, by supplemental agreement reasonably satisfactory in form and
substance to the Warrant Holder, the


                                         6

<PAGE>

due and punctual performance and observance of each and every covenant and
condition of this Warrant to be performed and observed by the Company.

                  (e) RECLASSIFICATION, ETC. If at any time after the date
hereof there shall be a reorganization or reclassification of the securities as
to which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, then the Warrant Holder
shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified herein and upon payment of the Purchase Price then in
effect, the number of shares or other securities or property resulting from such
reorganization or reclassification, which would have been received by the
Warrant Holder for the shares of stock subject to this Warrant had this Warrant
at such time been exercised.

                  (f) PURCHASE PRICE ADJUSTMENT. In the event that within twelve
(12) months of the Closing Date the Company issues or sells any Common Stock or
securities which are convertible into or exchangeable for its Common Stock or
any convertible securities, or any warrants or other rights to subscribe for or
to purchase or any options for the purchase of its Common Stock or any such
convertible securities (other than (i) shares or options issued or which may be
issued to employees, directors or consultants, or pursuant to the Company's
employee or director option plans, (ii) shares issued upon exercise of warrants
issued prior to the date hereof to John Hancock Mutual Life Insurance Co. and
its affiliates, (iii) shares issued upon exercise of warrants issued prior to
the date hereof in conjunction with the Company's issuance of Series A Preferred
Stock, and (iv) shares issued upon exercise of options, warrants or rights
outstanding on the date of the Agreement and listed in any of the Company's
reports filed under the Exchange Act during the previous 12 months) at an
effective purchase price per share which is less than the greater of the
Purchase Price then in effect or the fair market value (as defined in Section
3(b) above) of the Common Stock on the Trading Day next preceding such issue or
sale, then in each such case, the Purchase Price in effect immediately prior to
such issue or sale shall be reduced effective concurrently with such issue or
sale to an amount determined by multiplying the Purchase Price then in effect by
a fraction, (x) the numerator of which shall be the sum of (1) the number of
shares of Common Stock outstanding immediately prior to such issue or sale, plus
(2) the number of shares of Common Stock which the aggregate consideration
received by the Company for such additional shares would purchase at such fair
market value or, Purchase Price as the case may be, then in effect; and (y) the
denominator of which shall be the number of shares of Common Stock of the
Company outstanding immediately after such issue or sale.

         For the purposes of the foregoing adjustment, in the case of the
issuance of any convertible securities, warrants, options or other rights to
subscribe for or to purchase or exchange for, shares of Common Stock
("CONVERTIBLE SECURITIES"), the maximum number of shares of Common Stock
issuable upon exercise, exchange or conversion of such Convertible Securities
shall be deemed to be outstanding, provided that no further adjustment shall be
made upon the actual issuance of Common Stock upon exercise, exchange or
conversion of such Convertible Securities.

         The number of shares which may be purchased hereunder shall be
increased proportionately to any reduction in Purchase Price pursuant to this
paragraph 6(f), so that after such adjustments the aggregate Purchase Price
payable hereunder for the increased number of shares shall be the same as the
aggregate Purchase Price in effect just prior to such adjustments.

                                       7

<PAGE>

         In the event of any such issuance for a consideration which is less
than such fair market value and also less than the Purchase Price then in
effect, than there shall be only one such adjustment by reason of such issuance,
such adjustment to be that which results in the greatest reduction of the
Purchase Price computed as aforesaid.

         7. NO IMPAIRMENT. The Company will not, by amendment of its Articles of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the Warrant Holder against
impairment. Without limiting the generality of the foregoing, the Company (a)
will not increase the par value of any Warrant Shares above the amount payable
therefor on such exercise, and (b) will take all such action as may be
reasonably necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares on the exercise of
this Warrant.

         8. NOTICE OF ADJUSTMENTS. Whenever the Purchase Price, Repurchase
Price, or number of Shares purchasable hereunder shall be adjusted pursuant to
Section 6 hereof, the Company shall execute and deliver to the Warrant Holder a
certificate setting-forth, in reasonable detail, the event requiring the
adjustment, the amount of the adjustment, the method by which such adjustment
was calculated and the Purchase Price or the Repurchase Price and number of
shares purchasable hereunder after giving effect to such adjustment, and shall
cause a copy of such certificate to be mailed (by first class mail, postage
prepaid) to the Warrant Holder.

         9. RIGHTS AS SHAREHOLDER. Prior to exercise of this Warrant, the
Warrant Holder shall not be entitled to any rights as a shareholder of the
Company with respect to the Warrant Shares, including (without limitation) the
right to vote such shares, receive dividends or other distributions thereon or
be notified of shareholder meetings. However, in the event of any taking by the
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Company shall mail to
each Warrant Holder, at least 10 Trading Days prior to the date specified
therein, a notice specifying the date on which any such record date is to be
taken for the purpose of such dividend, distribution or right, and the amount
and character of such dividend, distribution or right.

         10. LIMITATION ON EXERCISE. Notwithstanding anything to the contrary
contained herein, this Warrant may not be exercised by the Warrant Holder to the
extent that, after giving effect to Warrant Shares to be issued pursuant to a
Subscription Notice, the total number of shares of Common Stock deemed
beneficially owned by such holder (other than by virtue of ownership of this
Warrant, or ownership of other securities that have limitations on the holder's
rights to convert or exercise similar to the limitations set forth herein),
together with all shares of Common Stock deemed beneficially owned by the holder
is "affiliates" (as defined in Rule 144 of the Act) that would be aggregated for
purposes of determining whether a group under Section 13(d) of the Exchange Act
exists, would exceed the Warrant Holder's Restricted Ownership Percentage


                                         8

<PAGE>

specified on Schedule I to the Agreement; PROVIDED that (w) each Warrant Holder
shall have the right at any time and from time to time to reduce its Restricted
Ownership Percentage immediately upon notice to the Company or in the event of a
Change in Control Transaction, (x) each Warrant Holder shall have the right at
any time and from time to time to increase its Restricted Ownership Percentage
or otherwise waive in whole or in part the restrictions of this Section 10 upon
61 days' prior notice to the Company or immediately in the event of a Change in
Control Transaction, (y) each Warrant Holder can make subsequent adjustments
pursuant to (w) or (x) any number of times from time to time (which adjustment
shall be effective immediately if it results in a decrease in the Restricted
Ownership Percentage or shall be effective upon 61 days' prior written notice or
immediately in the event of a Change in Control Transaction if it results in an
increase in the Restricted Ownership Percentage) and (z) each Warrant Holder may
eliminate or reinstate this limitation at any time and from time to time (which
elimination will be effective upon 61 days' prior notice and which reinstatement
will be effective immediately). Without limiting the foregoing, in the event of
a Change in Control Transaction, any holder may reinstate immediately (in whole
or in part) the requirement that any increase in its Restricted Ownership
Percentage be subject to 61 days' prior written notice, notwithstanding such
Change in Control Transaction, without imposing such requirement on, or
otherwise changing such holder's rights with respect to, any other Change in
Control Transaction. For this purpose, any material modification of the terms of
a Change in Control Transaction will be deemed to create a new Change in Control
Transaction. The term "DEEMED BENEFICIALLY OWNED" as used in this Warrant shall
exclude shares that might otherwise be deemed beneficially owned by reason of
the convertibility of the Preferred Shares. A "CHANGE IN CONTROL TRANSACTION"
will be deemed to have occurred upon the earlier of the announcement or
consummation of a transaction or series of transactions (other than the Merger)
involving (x) any consolidation or merger of the Company with or into any other
corporation or other entity or person (whether or not the Company is the
surviving corporation), or any other corporate reorganization or transaction or
series of related transactions in which in excess of 50% of the Company's voting
power is transferred through a merger, consolidation, tender offer or similar
transaction, or (y) in excess of 50% of the Corporation's Board of Directors
consists of directors not nominated by the prior Board of Directors of the
Company, or (z) any person (as defined in Section 13(d) of the Exchange Act,
together with its affiliates and associates (as such terms are defined in Rule
405 under the Act), beneficially owns or is deemed to beneficially own (as
described in Rule 13d-3 under the Exchange Act without regard to the 60-day
exercise period) in excess of 50% of the Company's voting power. The delivery of
a Subscription Notice by the Warrant Holder shall be deemed a representation by
such holder that it is in compliance with this paragraph.

         11. REPLACEMENT OF WARRANT. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
