violation or alleged violation of law by the Holder or any other Person, and
irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of
Warrant Shares. Nothing herein shall limit a Holder's right to pursue any other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with

taxes and expenses shall be paid by the Company; 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 any certificates for Warrant Shares

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.

substitution for and upon cancellation hereof, or in lieu of and substitution

                                       3
<PAGE>

         8. RESERVATION OF WARRANT SHARES. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued and otherwise unreserved 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 contingent purchase rights of Persons other than the Holder (taking into
account the adjustments and restrictions of SECTION 9). The Company covenants
that all Warrant Shares 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.

         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.

                  (a) STOCK DIVIDENDS AND SPLITS. If the Company, at any time
while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock
or otherwise makes a distribution on any class of capital stock that is payable
in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock
into a larger number of shares, or (iii) combines outstanding shares of Common
Stock into a smaller number of shares, then in each such case the Exercise Price
shall be multiplied by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding immediately before such event and of which
the denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this
paragraph shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or
combination.

                  (b) FUNDAMENTAL TRANSACTIONS. If, at any time while this
Warrant is outstanding there is a Fundamental Transaction, then the Holder shall
have the right thereafter to receive, upon exercise of this Warrant, the same
amount and kind of securities, cash or property as it would have been entitled
to receive upon the occurrence of such Fundamental Transaction if it had been,
immediately prior to such Fundamental Transaction, the holder of the number of
Warrant Shares then issuable upon exercise in full of this Warrant (the
"ALTERNATE CONSIDERATION"). For purposes of any such exercise, the determination
of the Exercise Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect
of one share of Common Stock in such Fundamental Transaction, and the Company
shall apportion the Exercise Price among the Alternate Consideration in a
reasonable manner reflecting the relative value of any different components of
the Alternate Consideration. If holders of Common Stock are given any choice as
to the securities, cash or property to be received in a Fundamental Transaction,
then the Holder shall be given the same choice as to the Alternate Consideration
it receives upon any exercise of this Warrant following such Fundamental
Transaction. At the Holder's option and request, any successor to the Company or
surviving entity in such Fundamental Transaction shall, either (1) issue to the
Holder a new warrant substantially in the form of this Warrant and consistent
with the foregoing provisions and evidencing the Holder's right to purchase the
Alternate Consideration for the aggregate Exercise Price upon exercise thereof,
or (2) purchase the Warrant from the Holder for a purchase price, payable in


                                       4
<PAGE>

cash within five Trading Days after such request (or, if later, on the effective
date of the Fundamental Transaction), equal to the Black Scholes value of the
remaining unexercised portion of this Warrant on the date of such request. The
terms of any agreement pursuant to which a Fundamental Transaction is effected
shall include terms requiring any such successor or surviving entity to comply
with the provisions of this paragraph (c) and insuring that the Warrant (or any
such replacement security) will be similarly adjusted upon any subsequent
transaction analogous to a Fundamental Transaction.

                  (c) CERTAIN NEW TRANSACTIONS. For purposes of this Section
9(c), "New Transaction" means the offer or sale of new common stock in a capital
raising or other financing transaction by or on behalf of the Company to a new
investor in a transaction offered or consummated after the date hereof;
PROVIDED, HOWEVER, that it is specifically understood that the term "New
Transaction" does not include (i) the sale of the Securities to the Purchaser
and other Purchasers, (ii) the issuance of Common Stock upon the exercise or
conversion of options, warrants, or convertible securities outstanding at the
date hereof or in connection with a put exercised by the Company pursuant to the
terms of an equity line agreement in effect on the date hereof, (iii) the
issuance of options or warrants hereafter granted to employees or consultants
for compensatory purposes or the issuance of Common Stock upon the exercise of
such options or warrants, (iv) the issuance of Common Stock or securities
exercisable for or convertible into Common Stock in connection with a merger,
acquisition or other business combination or a strategic partnering or joint
venture transaction or the exercise or conversion of such securities, (v) the
issuance of Common Stock or securities exercisable for or convertible into
Common Stock in connection with the settlement of claims which are the subject
of law suits, arbitrations and similar proceedings or the conversion or exercise
of such securities, and (vi) the issuance of warrants to equipment lessors in
connection with capital lease transactions or the exercise of such warrants. If
within 180 days of the Original Issue Date, the Company consummates a New
Transaction in which it sells or is deemed to sell Common Stock or securities
exercisable for or convertible into Common Stock at a lower price than the
Shares, or issues warrants with an exercise price lower than the Warrants, then
the Company shall issue additional shares of Common Stock so that the effective
price per share for the Shares equals the price of the new shares and if the
Company issues warrants, the exercise price of the Warrants will be lowered to
the price of the new warrants.

                  (d) NUMBER OF WARRANT SHARES. Simultaneously with any
adjustment to the Exercise Price pursuant to this Section 9, the number of
Warrant Shares that may be purchased upon exercise of this Warrant shall be
increased or decreased proportionately, so that after such adjustment the
aggregate Exercise Price payable hereunder for the adjusted number of Warrant
Shares shall be the same as the aggregate Exercise Price in effect immediately
prior to such adjustment.

                  (e) CALCULATIONS. All calculations under this SECTION 9 shall
be made to the nearest cent or the nearest 1/100th of a share, as applicable.
The number of shares of Common Stock 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.


                                       5
<PAGE>

                  (f) NOTICE OF ADJUSTMENTS. Upon the occurrence of each
adjustment pursuant to this SECTION 9, the Company at its expense will promptly
compute such adjustment in accordance with the terms of this Warrant and prepare
a certificate setting forth such adjustment, including a statement of the
adjusted Exercise Price and adjusted number or type of Warrant Shares or other
securities issuable upon exercise of this Warrant (as applicable), describing
the transactions giving rise to such adjustments and showing in detail the facts
upon which such adjustment is based. Upon written request, the Company will
promptly deliver a copy of each such certificate to the Holder and to the
Company's Transfer Agent.

                  (g) NOTICE OF CORPORATE EVENTS. If the Company (i) declares a
dividend or any other distribution of cash, securities or other property in
respect of its Common Stock, including without limitation any granting of rights
or warrants to subscribe for or purchase any capital stock of the Company or any
Subsidiary, (ii) authorizes or approves, enters into any agreement contemplating
or solicits stockholder approval for any Fundamental Transaction or (iii)
authorizes the voluntary dissolution, liquidation or winding up of the affairs
of the Company, then the Company shall deliver to the Holder a notice describing
the material terms and conditions of such transaction (but only to the extent
such disclosure would not result in the dissemination of material, non-public
information to the Holder) at least 10 calendar days prior to the applicable
record or effective date on which a Person would need to hold Common Stock in
order to participate in or vote with respect to such transaction, and the
Company will take all steps reasonably necessary in order to insure that the
Holder is given the practical opportunity to exercise this Warrant prior to such
time so as to participate in or vote with respect to such transaction; provided,
however, that the failure to deliver such notice or any defect therein shall not
affect the validity of the corporate action required to be described in such
notice.

         10. PAYMENT OF EXERCISE PRICE. The Holder may pay the Exercise Price in
one of the following manners:

                  (a) CASH EXERCISE. The Holder may deliver immediately
available funds; or

                  (b) CASHLESS EXERCISE. If an Exercise Notice is delivered at a
time when a registration statement permitting the Holder to resell the Warrant
Shares is not then effective or the prospectus forming a part thereof is not
then available to the Holder for the resale of the Warrant Shares, then the
Holder may notify the Company in an Exercise Notice of its election to utilize
cashless exercise, in which event the Company shall issue to the Holder the
number of Warrant Shares determined as follows:

                                  X = Y [(A-B)/A]

                         where:

                                  X = the number of Warrant Shares to be issued
                                  to the Holder.

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

                                  A = the average of the closing prices for
                                  the five Trading Days immediately prior to
                                  (but not including) the Exercise Date.

                                  B = the Exercise Price.


                                       6
<PAGE>

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.

         11. LIMITATIONS ON EXERCISE.

                  (a) Notwithstanding anything to the contrary contained herein,
the number of Warrant Shares that may be acquired by the Holder upon any
exercise of this Warrant (or otherwise in respect hereof) shall be limited to
the extent necessary to insure that, following such exercise (or other
issuance), the total number of shares of Common Stock then beneficially owned by
such Holder and its Affiliates and any other Persons whose beneficial ownership
of Common Stock would be aggregated with the Holder's for purposes of Section
13(d) of the Exchange Act, does not exceed 4.999% of the total number of issued
and outstanding shares of Common Stock (including for such purpose the shares of
Common Stock issuable upon such exercise). For such purposes, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder. 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 Fundamental
Transaction as contemplated in Section 9 of this Warrant. By written notice to
the Company, an Investor may waive the provisions of this Section 11(a) as to
itself but any such waiver will not be effective until the 61st day after
delivery thereof and such waiver shall have no effect on any other Investor.

                  (b) Notwithstanding anything to the contrary contained herein,
the number of Warrant Shares that may be acquired by the Holder upon any
exercise of this Warrant (or otherwise in respect hereof) shall be limited to
the extent necessary to insure that, following such exercise (or other
issuance), the total number of shares of Common Stock then beneficially owned by
such Holder and its Affiliates and any other Persons whose beneficial ownership
of Common Stock would be aggregated with the Holder's for purposes of Section
13(d) of the Exchange Act, does not exceed 9.999% of the total number of issued
and outstanding shares of Common Stock (including for such purpose the shares of
Common Stock issuable upon such exercise). For such purposes, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder. 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 Fundamental
Transaction as contemplated in Section 9 of this Warrant. This restriction may
not be waived.

         12. NO FRACTIONAL SHARES. No fractional shares of Warrant Shares will
be issued in connection with any exercise of this Warrant. In lieu of any
fractional shares which would, otherwise be issuable, the Company shall pay cash
equal to the product of such fraction multiplied by the closing price of one
Warrant Share as reported by the applicable Trading Market on the date of
exercise.

Warrant. Upon 10 days' notice to the Holder, the Company may appoint a new
warrant agent. 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

disclosure in a registration statement or prospectus, as determined reasonably
and in good faith by the Chief Executive Officer or the Board of Directors of

the business and affairs of the Company; or (b) any material engagement or
activity by the Company which would, in the reasonable and good faith
determination of the Chief Executive Officer or the Board of Directors of the

statement or prospectus at such time.

                           (ii) "EXCHANGE ACT" shall mean the Securities
Exchange Act of 1934, as amended.

                           (iii) "INCLUDED SHARES" shall mean any Registrable

of such shares.

                           (v) "REGISTRATION" shall mean a registration of
securities under the Securities Act pursuant to Section 15(b) of this Agreement.

                           (vi) "REGISTRATION PERIOD" with respect to any

                           (vii) "REGISTRATION STATEMENT" shall mean the
registration statement, as amended from time to time, filed with the SEC in
connection with a Registration.

Commission.

                  (b) PIGGYBACK REGISTRATION. Unless the Registrable Shares are
then included in a Registration Statement or can be sold under the provisions of
Rule 144 without limitation as to volume, whether pursuant to Rule 144(k) or
otherwise, if the Company shall determine to register any Common Stock under the
Securities Act for sale in connection with a public offering of Common Stock
(other than pursuant to an employee benefit plan or a merger, acquisition or
similar transaction), the Company will give written notice thereof to Holder and
will include in such Registration Statement any of the Registrable Shares which
Holder may request be included ("INCLUDED SHARES") by a writing delivered to the
Company within 15 days after the notice given by the Company to Holder;
PROVIDED, HOWEVER, that if the offering is to be firmly underwritten, and the
representative of the underwriters of the offering refuse in writing to include
in the offering all of the shares of Common Stock requested by the Company and
others, the shares to be included shall be allocated first to the Company and
any shareholder who initiated such Registration and then among the others based
on the respective number of shares of Common Stock held by such persons. If the
Company decides not to, and does not, file a Registration Statement with respect
to such Registration, or after filing determines to withdraw the same before the
effective date thereof, the Company will promptly so inform Holder, and will not
be obligated to complete the registration of the Included Shares included
therein.

                           (i) the Company shall take all lawful action such
that the Registration Statement, any amendment thereto and the prospectus
forming a part thereof does not contain an 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 are
made, not misleading. Upon becoming aware of the occurrence of any event or the
discovery of any facts during the Registration Period that make any statement of
a material fact made in the Registration Statement or the related prospectus
untrue in any material respect or which material fact is omitted from the
Registration Statement or related prospectus that requires the making of any
changes in the Registration Statement or related prospectus so that it will not
contain any untrue statement of a material fact or omit to state a material fact


                                       9
<PAGE>

necessary to make the statements therein, in light of the circumstances under
which they are made, not misleading (taking into account any prior amendments or
supplements), the Company shall promptly notify Holder, and, subject to the
provisions of Section 9.5, as soon as reasonably practicable prepare (but,
subject to Section 9.5, in no event more than five business days in the case of
a supplement or seven business days in the case of a post-effective amendment)
and file with the SEC a supplement or post-effective amendment to the
Registration Statement or the related prospectus or file any other required
document so that, as thereafter delivered to a purchaser of Shares from Holder,
such prospectus will not contain any untrue statement of a material fact or omit
to state a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

                           (ii) At least three business days prior to the filing
with the SEC of the Registration Statement (or any amendment thereto) or the
prospectus forming a part thereof (or any supplement thereto), the Company shall
provide draft copies thereof to Holder and shall consider incorporating into
such documents such comments as Holder (and its counsel) may propose to be
incorporated therein. Notwithstanding the foregoing, no prospectus supplement,
the form of which has previously been provided to Holder, need be delivered in
draft form to Holder.

                           (iii) the Company shall promptly notify Holder upon
the occurrence of any of the following events in respect of the Registration
Statement or the prospectus forming a part thereof: (i) the receipt of any
request for additional information from the SEC or any other federal or state
governmental authority, the response to which would require any amendments or
supplements to the Registration Statement or related prospectus; (ii) the
issuance by the SEC or any other federal or state governmental authority of any
stop order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for that purpose; or (iii) the receipt of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Shares for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose.

                           (iv) the Company shall furnish to Holder with respect
to the Included Shares registered under the Registration Statement (and to each
underwriter, if any, of such Shares) such number of copies of prospectuses and
such other documents as Holder may reasonably request, in order to facilitate
the public sale or other disposition of all or any of the Included Shares by
Holder pursuant to the Registration Statement.

                           (v) In connection with any registration pursuant to
Section 9.2, the Company shall file or cause to be filed such documents as are
required to be filed for normal Blue Sky clearance in states specified in
writing by Holder; PROVIDED, HOWEVER, that the Company shall not be required to
qualify to do business or consent to service of process in any jurisdiction in
which it is not now so qualified or has not so consented.

                           (vi) the Company shall bear and pay all expenses
incurred by it and Holder (other than underwriting discounts, brokerage fees and
commissions and fees and expenses of more than one law firm) in connection with
the registration of the Shares pursuant to the Registration Statement.


                                       10
<PAGE>

                           (vii) As a condition to including Registrable Shares
in a Registration Statement, Holder must provide to the Company such information
regarding itself, the Registrable Shares held by it and the intended method of
distribution of such Shares as shall be required to effect the registration of
the Registrable Shares and, if the offering is being underwritten, Holder must
provide such powers of attorney, indemnities and other documents as may be
reasonably requested by the managing underwriter.

                           (viii) Following the effectiveness of the
Registration Statement, upon receipt from the Company of a notice that the
Registration Statement contains an untrue statement of material fact or omits to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances under which they
were made, Holder will immediately discontinue disposition of Included Shares
pursuant to the Registration Statement until the Company notifies Holder that it
may resume sales of Included Shares and, if necessary, provides to Holder copies
of the supplemental or amended prospectus.

                  (d) BLACKOUT EVENT. The Company shall not be obligated to file
a post-effective amendment or supplement to the Registration Statement or the
prospectus constituting a part thereof during the continuance of a Blackout
Event; provided, however, that no Blackout Event may be deemed to exist for more
than 60 days. Without the express written consent of Holder, if required to
permit the continued sale of Shares by Holder, a post-effective amendment or
supplement to Registration Statement or the prospectus constituting a part
thereof must be filed no later than the 61st day following commencement of a
Blackout Event.

                  (e) RULE 144. With a view to making available to Holder the
benefits of Rule 144, the Company agrees, until Holder can sell all remaining
Registrable Shares under the provisions Rule 144(k), to:

                           a) comply with the provisions of paragraph (c)(1) of
Rule 144; and

                           b) file with the SEC in a timely manner all reports
and other documents required to be filed by the Company pursuant to Section 13
or 15(d) under the Exchange Act; and, if at any time it is not required to file
such reports but in the past had been required to or did file such reports, it
will, upon the request of a Purchaser, make available other information as
required by, and so long as necessary to permit sales of its Shares pursuant to,
Rule 144.

                  (f) INDEMNIFICATION BY THE COMPANY. the Company agrees to
indemnify and hold harmless Holder, and its officers, directors and agents, and
each person, if any, who controls Holder within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages and liabilities caused by (i) any violation or alleged
violation by the Company of the Securities Act, Exchange Act, any state
securities laws or any rule or regulation promulgated under the Securities Act,
Exchange Act or any state securities laws, (ii) any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or
prospectus relating to the Included Shares (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus, or (iii) caused by any omission or alleged omission to
state therein a material fact required to be stgggated therein or necessary to
make the statements therein not misleading in light of the circumstances under
which they were made, except insofar as such losses, claims, damages or


                                       11
<PAGE>

liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information furnished in writing to the
Company by Holder or on Holder's behalf expressly for use therein.

                  (g) INDEMNIFICATION BY HOLDER. Holder agrees to indemnify and
hold harmless the Company, its officers, directors and agents and each person,
if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to Holder, but only with respect to
information furnished in writing by Holder or on Holder's behalf expressly for
use in any registration statement or prospectus relating to the Registrable
Shares, or any amendment or supplement thereto, or any preliminary prospectus.

                  (h) INDEMNIFICATION PROCEDURES. In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to this Section 15,
such person (an "INDEMNIFIED Party") shall promptly notify the person against
whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party, and shall assume the
payment of all fees and expenses; provided that the failure of any Indemnified
Party so to notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder except to the extent (and only to the extent
that) that the Indemnifying Party is materially prejudiced by such failure to
notify. In any such proceeding, any Indemnified Party shall have the right to
retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of such Indemnified Party representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the Indemnifying Party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties (including in the case of Holder, all of its
officers, directors and controlling persons) and that all such fees and expenses
shall be reimbursed as they are incurred. In the case of any such separate firm
for the Indemnified Parties, the Indemnified Parties shall designate such firm
in writing to the Indemnifying Party. The Indemnifying Party shall not be liable
for any settlement of any proceeding effected without its written consent (which
consent shall not be unreasonably withheld or delayed), but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any loss or liability (to the extent stated above) by reason of such
settlement or judgment. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Party is or could have
been a party and indemnity could have been sought hereunder by such Indemnified
Party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such proceeding.

                  (i) CONTRIBUTION. To the extent any indemnification by an
Indemnifying Party is prohibited or limited by law, the Indemnifying Party
agrees to make the maximum contribution with respect to any amounts for which,
he, she or it would otherwise be liable under this Section 15(i) to the fullest


                                       12
<PAGE>

extent permitted by law; provided, however, that (i) no contribution shall be
made under circumstances where a party would not have been liable for
indemnification under this Section 10.6 and (ii) no seller of Registrable
Securities guilty of fraudulent misrepresentation (within the meaning used in
the Securities Act) shall be entitled to contribution from any party who was not
guilty of such fraudulent misrepresentation. If the Company shall determine to
register any Common Stock under the Securities Act for sale in connection with a
public offering of Common Stock (other than pursuant to an employee benefit plan
or a merger, acquisition or similar transaction), the Company will give written
notice thereof to Holder and will include in such registration any of the
Registrable Shares which Holder may request be included ("INCLUDED SHARES") by a
writing delivered to the Company within 15 days after the notice given by the
Company to Holder; provided, however, that if the offering is to be firmly
underwritten, and the representative of the underwriters of the offering refuse
in writing to include in the offering all of the shares of Common Stock
requested by the Company and others, the shares to be included shall be
allocated first to the Company and any shareholder who initiated such
registration and then among the others based on the respective number of shares
of Common Stock held by such persons. If the Company decides not to, and does
not, file a registration statement with respect to such registration, or after
filing determines to withdraw the same before the effective date thereof, the
Company will promptly so inform Holder, and the Company will not be obligated to
complete the registration of the Included Shares included therein. The Company
will pay all costs and expenses of such registration other than underwriting
discounts or brokerage fees or commissions in connection with the sale of the
Included Shares and fees and costs of accountants, attorneys or others retained
by Holder. For purposes of this Agreement, "REGISTRABLE SHARES" shall mean the
shares of Common Stock (or such stock or securities as at the time are
receivable upon the exercise of these Warrants) issuable upon exercise of the
Warrants and any shares issued as a result of stock split, stock dividend or
reclassification of such shares; PROVIDED, HOWEVER, that any share shall cease
to be a Registrable Share if and when (a) it has been effectively registered
under the Securities Act and disposed of pursuant thereto, or (b) the holder may
sell such share (or in the case of a share not yet issued under this Warrant,
the holder may exercise this Warrant, including pursuant to Section 1.4, and
sell such share issued upon such exercise) in the market on which the Company
common stock is then traded without registration under the Securities Act.

                  (j) In connection with any registration under this Section 15,
the Company will:

                           (i) furnish to Holder a copy of the registration
statement and each amendment to the registration statement and such number of
copies of the final prospectus included in the registration statement as Holder
may reasonably request in order to facilitate the distribution of the Included
Shares owned by Holders; and

                           (ii) notify Holder of the issuance of any stop order
by the Securities and Exchange Commission in connection with the registration
statement.

                  (k) As a condition to including Registrable Shares in the
registration statement, Holder must provide to the Company such information
regarding itself, the Registrable Shares held by it and the intended method of
distribution of such Shares as shall be required to effect the registration of


                                       13
<PAGE>

the Registrable Shares and, if the offering is being underwritten, Holder must
provide such powers of attorney, indemnities and other documents as may be
reasonably requested by the managing underwriter.

                  (l) Following the effectiveness of the registration statement,
upon receipt from the Company of a notice that the registration statement
contains an untrue statement of material fact or omits to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances under which they were made, Holder
will immediately discontinue disposition of Included Shares pursuant to the
registration statement until the Company notifies Holder that it may resume
sales of Included Shares and, if necessary, provides to Holder copies of the
supplemental or amended prospectus. In such event, Holder will deliver to the
Company all copies, other than permanent file copies then in Holder's
possession, of the most recent prospectus covering the Included Shares.

                  (m) The Company agrees to indemnify and hold harmless Holder,
and its officers, directors and agents, and each person, if any, who controls
Holder within the meaning of Section 15 of the Securities Act or Section 20 of
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") from and
against any and all losses, claims, damages and liabilities caused by (i) any
violation by the Company of the Securities Act, Exchange Act, any state
securities laws or any rule or regulation promulgated under the Securities Act,
Exchange Act or any state securities laws, (ii) any materially untrue statement
of a material fact contained in any registration statement or prospectus
relating to the Included Shares (as amended or supplemented if the Company shall
have furnished any amendments or supplements thereto) or any preliminary
prospectus, or (iii) caused by any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances under which they
were made, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information furnished in writing to the Company by Holder or
on Holder's behalf expressly for use therein.

                  (n) Holder agrees to indemnify and hold harmless the Company,
its officers, directors and agents and each person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act to the same extent as the foregoing indemnity from the
Company to Holder, but only with respect to information furnished in writing by
Holder or on Holder's behalf expressly for use in any registration statement or
prospectus relating to the Registrable Shares, or any amendment or supplement
thereto, or any preliminary prospectus.

                  (o) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to this Section 10, such person (an
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party, and shall assume the
payment of all fees and expenses; provided that the failure of any Indemnified
Party so to notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder except to the extent (and only to the extent
that) that the Indemnifying Party is materially prejudiced by such failure to
notify. In any such proceeding, any Indemnified Party shall have the right to


                                       14
<PAGE>

retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of such Indemnified Party representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the Indemnifying Party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties (including in the case of Holder, all of its
officers, directors and controlling persons) and that all such fees and expenses
shall be reimbursed as they are incurred. In the case of any such separate firm
for the Indemnified Parties, the Indemnified Parties shall designate such firm
in writing to the Indemnifying Party. The Indemnifying Party shall not be liable
for any settlement of any proceeding effected without its written consent (which
consent shall not be unreasonably withheld or delayed), but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any loss or liability (to the extent stated above) by reason of such
settlement or judgment. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Party is or could have
been a party and indemnity could have been sought hereunder by such Indemnified
Party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such proceeding.

         16. MISCELLANEOUS.

                  (a) This Warrant shall be binding on and inure to the benefit
of the parties hereto and their respective successors and assigns. Subject to
the preceding sentence, nothing in this Warrant shall be construed to give to
any Person other than the Company and the Holder any legal or equitable right,
remedy or cause of action under this Warrant. This Warrant may be amended only
in writing signed by the Company and the Holder and their successors and
assigns.

                  (b) All questions concerning the construction, validity,
enforcement and interpretation of this Warrant shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York (except for matters governed by corporate law in the State of Delaware),
without regard to the principles of conflicts of law thereof. Each party agrees
that all legal proceedings concerning the interpretations, enforcement and
defense of this Warrant and the transactions herein contemplated ("PROCEEDINGS")
(whether brought against a party hereto or its respective Affiliates, employees
or agents) shall be commenced exclusively in the New York Courts. Each party
hereto hereby irrevocably submits to the exclusive jurisdiction of the New York
Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein, and hereby
irrevocably waives, and agrees not to assert in any Proceeding, any claim that
it is not personally subject to the jurisdiction of any New York Court, or that
such Proceeding has been commenced in an improper or inconvenient forum. Each
party hereto hereby irrevocably waives personal service of process and consents
to process being served in any such Proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Warrant and


                                       15

agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing contained herein shall be deemed to limit in any way
any right to serve process in any manner permitted by law. Each party hereto
hereby irrevocably waives, to the fullest extent permitted by applicable law,
any and all right to trial by jury in any legal proceeding arising out of or
relating to this Warrant or the transactions contemplated hereby. If either
party shall commence a Proceeding to enforce any provisions of this Warrant,
then the prevailing party in such Proceeding shall be reimbursed by the other
party for its attorney's fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such Proceeding.

                  (c) 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.

                  (d) 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.

                  (e) Prior to exercise of this Warrant, the Holder hereof shall
not, by reason of being a Holder, be entitled to any rights of a stockholder
with respect to the Warrant Shares.
