furnished with or has had access at the EDGAR Website of the Commission to the
Company's Form 10-KSB for the year ended July 31, 2003 as filed with the
Commission, together with all subsequently filed Forms 10-QSB, 8-K, and filings
made with the Commission available at the EDGAR website (hereinafter referred to

financial condition and other matters as the Subscriber has requested in writing

advisability of investing in the Securities.

                           (b) Information on Subscriber. The Subscriber is, and
will be at the time of the conversion of the Common Stock and exercise of any of
the Warrants, an "accredited investor", as such term is defined in Regulation D
promulgated by the Commission under the 1933 Act, is experienced in investments
and business matters, has made investments of a speculative nature and has
purchased securities of United States publicly-owned companies in private
placements in the past and, with its representatives, has such knowledge and
experience in financial, tax and other business matters as to enable the
Subscriber to utilize the information made available by the Company to evaluate
the merits and risks of and to make an informed investment decision with respect

understands and agrees that the Securities have not been registered under the
1933 Act or any applicable state securities laws, by reason of their issuance in
a transaction that does not require registration under the 1933 Act (based in
part on the accuracy of the representations and warranties of Subscriber
contained herein), and that such Securities must be held indefinitely unless a
subsequent disposition is registered under the 1933 Act or any applicable state
securities laws or is exempt from such registration. In any event, and subject
to compliance with applicable securities laws, the Subscriber may enter into
hedging transactions with third parties, which may in turn engage in short sales
of the Securities in the course of hedging the position they assume and the
Subscriber may also enter into short positions or other derivative transactions
relating to the Securities, or interests in the Securities, and deliver the

                           (q) No Undisclosed Liabilities. The Company has no

concluded, in its good faith business judgment, that the issuance of the
Securities is in the best interests of the Company. The Company specifically
acknowledges that its obligation to issue the Securities is binding upon the

or the transactions contemplated hereby and arising out of such party's actions.
Anything to the contrary in this Agreement notwithstanding, each Subscriber is
providing indemnification only for such Subscriber's own actions and not for any
action of any other Subscriber. Each Subscriber's liability hereunder is several
and not joint. The Company agrees that it will pay the Finder a cash finder's
fee of nine percent (9%) of the Purchase Price but not to exceed $495,000
("Finder's Fees") directly out of the funds held pursuant to the Escrow
Agreement. The Company represents that there are no other parties entitled to
receive fees, commissions, or similar payments in connection with the Offering
except the Finder. The Finder will also be paid by the Company nine percent (9%)
of the cash proceeds received by the Company from Warrant exercise ("Warrant
Exercise Compensation"). The Warrant Exercise Compensation must be paid by the
Company to the Finder within five (5) days after each receipt by the Company of
Warrant Exercise cash proceeds.

                           (b) Finder's Warrants. On the Closing Date, the
Company will issue to the Finder Warrants identical to and carrying the same
rights as the Warrants issuable to the Subscribers except that the exercise
price to purchase one Warrant Share shall be $1.75 and the Warrants shall be
exercisable until three years after the Closing Date ("Finder's Warrants"). The
Finder will receive one (1) Warrant for each ten (10) Shares issued to the
Subscribers. All the representations, covenants, warranties, undertakings,
remedies, liquidated damages, indemnification, and other rights including but
not limited to registration rights made or granted to or for the benefit of the
Subscribers are hereby also made and granted to the Finder in respect of the
Finder's Warrants.

                  9. Covenants of the Company. The Company covenants and agrees
with the Subscribers as follows:

                           (a) Stop Orders. The Company will advise the
Subscribers, promptly after it receives notice of issuance by the Commission,
any state securities commission or any other regulatory authority of any stop
order or of any order preventing or suspending any offering of any securities of
the Company, or of the suspension of the qualification of the Common Stock of
the Company for offering or sale in any jurisdiction, or the initiation of any
proceeding for any such purpose.

                           (b) Listing. The Company shall promptly secure the
listing of the shares of Common
Stock and the Warrant Shares upon each national securities exchange, or
automated quotation system upon which they are or become eligible for listing
(subject to official notice of issuance) and shall maintain such listing so long
as any Warrants are outstanding. The Company will maintain the listing of its
Common Stock on the American Stock Exchange, Nasdaq SmallCap Market, Nasdaq
National Market System, Bulletin Board, or New York Stock Exchange (whichever of
the foregoing is at the time the principal trading exchange or market for the
Common Stock (the "Principal Market")), and will comply in all respects with the
Company's reporting, filing and other obligations under the bylaws or rules of
the Principal Market, as applicable. The Company will provide the Subscribers
copies of all notices it receives notifying the Company of the threatened and
actual delisting of the Common Stock from any Principal Market. As of the date
of this Agreement and the Closing Date, the Bulletin Board is and will be the
Principal Market.

                           (c) Market Regulations. The Company shall notify the
Commission, the Principal Market and applicable state authorities, in accordance
with their requirements, of the transactions contemplated by this Agreement, and
shall take all other necessary action and proceedings as may be required and
permitted by applicable law, rule and regulation, for the legal and valid
issuance of the Securities to the Subscribers and promptly provide copies
thereof to Subscriber.

                           (d) Reporting Requirements. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule
144, without regard to volume limitation, the Company will (v) cause its Common
Stock to continue to be registered under Section 12(b) or 12(g) of the 1934 Act,
(x) comply in all respects with its reporting and filing obligations under the
1934 Act, (y) comply with all reporting requirements that are applicable to an
issuer with a class of shares registered pursuant to Section 12(b) or 12(g) of
the 1934 Act, as applicable, and (z) comply with all requirements related to any
registration statement filed pursuant to this Agreement. The Company will use
its best efforts not to take any action or file any document (whether or not
permitted by the 1933 Act or the 1934 Act or the rules thereunder) to terminate
or suspend such registration or to terminate or suspend its reporting and filing
obligations under said acts until two (2) years after the Closing Date. Until
the earlier of the resale of the Common Stock and the Warrant Shares by each
Subscriber or at least two (2) years after the Warrants have been exercised, the
Company will use its best efforts to continue the listing or quotation of the
Common Stock on the Principal Market or other market with the reasonable consent
of Subscribers holding a majority of the Shares and Warrant Shares, and will
comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the Principal Market. The Company
agrees to file a Form D with respect to the Securities as required under
Regulation D and to provide a copy thereof to each Subscriber promptly after
such filing.

                           (e) Use of Proceeds. The Company undertakes to use
the proceeds of the Subscribers' funds for the purposes set forth on SCHEDULE
9(E) hereto. A deviation from the use of proceeds set forth on SCHEDULE 9(E) of
more than 10% per item or more than 20% in the aggregate shall be deemed a

                                       9
<PAGE>

material breach of the Company's obligations hereunder. Except as set forth on
SCHEDULE 9(E), the Purchase Price may not and will not be used for accrued and
unpaid officer and director salaries, payment of financing related debt,
redemption of outstanding redeemable notes or equity instruments of the Company
nor non-trade obligations outstanding on the Closing Date.

                           (f) Reservation. The Company undertakes to reserve,
pro rata on behalf of each Subscriber and holder of a Warrant, from its
authorized but unissued common stock, a number of common shares equal to the
amount of Warrant Shares issuable upon exercise of the Warrants. Failure to have
sufficient shares reserved pursuant to this Section 9(f) for three (3)
consecutive business days or ten (10) days in the aggregate shall be a material
default of the Company's obligations under this Agreement.

                           (g) Taxes. From the date of this Agreement and until
the sooner of (i) two (2) years after the Closing Date, or (ii) until all the
Shares and Warrant Shares have been resold or transferred by all the Subscribers
pursuant to the Registration Statement or pursuant to Rule 144, without regard
to volume limitations, the Company will promptly pay and discharge, or cause to
be paid and discharged, when due and payable, all lawful taxes, assessments and
governmental charges or levies imposed upon the income, profits, property or
business of the Company; provided, however, that any such tax, assessment,
charge or levy need not be paid if the validity thereof shall currently be
contested in good faith by appropriate proceedings and if the Company shall have
set aside on its books adequate reserves with respect thereto, and provided,
further, that the Company will pay all such taxes, assessments, charges or
levies forthwith upon the commencement of proceedings to foreclose any lien
which may have attached as security therefore.

                           (h) Insurance. From the date of this Agreement and
until the sooner of (i) two (2) years after the Closing Date, or (ii) until all
the Shares and Warrant Shares have been resold or transferred by all the
Subscribers pursuant to the Registration Statement or pursuant to Rule 144,
without regard to volume limitations, the Company will keep its assets which are
of an insurable character insured by financially sound and reputable insurers
against loss or damage by fire, explosion and other risks customarily insured
against by companies in the Company's line of business, in amounts sufficient to
prevent the Company from becoming a co-insurer and not in any event less than
one hundred percent (100%) of the insurable value of the property insured; and
the Company will maintain, with financially sound and reputable insurers,
insurance against other hazards and risks and liability to persons and property
to the extent and in the manner customary for companies in similar businesses
similarly situated and to the extent available on commercially reasonable terms.

                           (i) Books and Records. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule
144, without regard to volume limitations, the Company will keep true records
and books of account in which full, true and correct entries will be made of all
dealings or transactions in relation to its business and affairs in accordance
with generally accepted accounting principles applied on a consistent basis.

                           (j) Governmental Authorities. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule
144, without regard to volume limitations, the Company shall duly observe and
conform in all material respects to all valid requirements of governmental
authorities relating to the conduct of its business or to its properties or
assets.

                           (k) Intellectual Property. From the date of this
Agreement and until the sooner of (i) two (2) years after the Closing Date, or
(ii) until all the Shares and Warrant Shares have been resold or transferred by
all the Subscribers pursuant to the Registration Statement or pursuant to Rule
144, without regard to volume limitations, the Company shall maintain in full
force and effect its corporate existence, rights and franchises and all licenses
and other rights to use intellectual property owned or possessed by it and
reasonably deemed to be necessary to the conduct of its business.

                           (l) Properties. From the date of this Agreement and
until the sooner of (i) two (2) years after the Closing Date, or (ii) until all
the Shares and Warrant Shares have been resold or transferred by all the
Subscribers pursuant to the Registration Statement or pursuant to Rule 144,
without regard to volume limitation, the Company will keep its properties in
good repair, working order and condition, reasonable wear and tear excepted, and
from time to time make all necessary and proper repairs, renewals, replacements,
additions and improvements thereto; and the Company will at all times comply
with each provision of all leases to which it is a party or under which it
occupies property if the breach of such provision could reasonably be expected
to have a material adverse effect.

                           (m) Confidentiality/Public Announcement. From the
date of this Agreement and until the sooner of (i) two (2) years after the
Closing Date, or (ii) until all the Shares and Warrant Shares have been resold
or transferred by all the Subscribers pursuant to the Registration Statement or
pursuant to Rule 144, without regard to volume limitations, the Company agrees
that it will not disclose publicly or privately the identity of the Subscribers
unless expressly agreed to in writing by a Subscriber or only to the extent
required by law and then only upon ten days prior notice to Subscriber. The
Company may identify the Subscribers in any registration statement filed
pursuant to Section 11 of this Agreement. In any event and subject to the
foregoing, the Company undertakes to file a form 8-K or make a public
announcement describing the Offering not later than the Closing Date. In the
form 8-K or public announcement, the Company will specifically disclose the
amount of common stock outstanding immediately after the Closing.

                           (n) Further Registration Statements. Except for a
registration statement filed on behalf of the Subscribers pursuant to Section 11
of this Agreement, the Company will not file any registration statements,
including but not limited to Form S-8, with the Commission or with state
regulatory authorities without the consent of the Subscriber until one hundred
and eighty (180) days after the Actual Effective Date during which such
Registration Statement shall be current and available for use in connection with
the public resale of the Shares and Warrant Shares ("Exclusion Period").

                           (o) Blackout. The Company undertakes and covenants
that until the first to occur of (i) the end of the Exclusion Period, or (ii)
until all the Shares and Warrant Shares have been resold pursuant to such
registration statement, the Company will not enter into any acquisition, merger,
exchange or sale or other transaction that could have the effect of delaying the
effectiveness of any pending registration statement or causing an already
effective registration statement to no longer be effective or current.

                  10. Covenants of the Company and Subscriber Regarding
Indemnification.

                           (a) The Company agrees to indemnify, hold harmless,
reimburse and defend the Subscribers, the Subscribers' officers, directors,
agents, affiliates, control persons, and principal shareholders, against any
claim, cost, expense, liability, obligation, loss or damage (including
reasonable legal fees) of any nature, incurred by or imposed upon the Subscriber
or any such person which results, arises out of or is based upon (i) any
material misrepresentation by Company or breach of any warranty by Company in
this Agreement or in any Exhibits or Schedules attached hereto, or other

                                       11
<PAGE>

agreement delivered pursuant hereto; or (ii) after any applicable notice and/or
cure periods, any breach or default in performance by the Company of any
covenant or undertaking to be performed by the Company hereunder, or any other
agreement entered into by the Company and Subscriber relating hereto.

                           (b) Each Subscriber agrees to indemnify, hold
harmless, reimburse and defend the Company and each of the Company's officers,
directors, agents, affiliates, control persons against any claim, cost, expense,
liability, obligation, loss or damage (including reasonable legal fees) of any
nature, incurred by or imposed upon the Company or any such person which
results, arises out of or is based upon (i) any material misrepresentation by
such Subscriber in this Agreement or in any Exhibits or Schedules attached
hereto, or other agreement delivered pursuant hereto; or (ii) after any
applicable notice and/or cure periods, any breach or default in performance by
such Subscriber of any covenant or undertaking to be performed by such
Subscriber hereunder, or any other agreement entered into by the Company and
Subscribes relating hereto.

                           (c) In no event shall the liability of any Subscriber
or permitted successor hereunder or under any other agreement delivered in
connection herewith be greater in amount than the dollar amount of the net
proceeds actually received by such Subscriber upon the sale of Registrable
Securities (as defined herein).

                           (d) The procedures set forth in Section 11.6 shall
apply to the indemnifications set forth in Sections 10(a) and 10(b) above.

                  11.1. Registration Rights. The Company hereby grants the
following registration rights to holders of the Securities.

                           (i) On one occasion, for a period commencing one
hundred and twenty-one (121) days after the Closing Date, but not later than two
(2) years after the Closing Date ("Request Date"), upon a written request
therefor from any record holder or holders of more than 50% of the Shares and
Warrant Shares actually issued upon exercise of the Warrants, the Company shall
prepare and file with the Commission a registration statement under the 1933 Act
registering the Shares and Warrant Shares including Warrant Shares issuable upon
exercise of the Finder's Warrants (collectively "Registrable Securities") which
are the subject of such request for unrestricted public resale by the holder
thereof. For purposes of Sections 11.1(i) and 11.1(ii), Registrable Securities
shall not include Securities which are registered for resale in an effective
registration statement or included for registration in a pending registration
statement, or which have been issued without further transfer restrictions after
a sale or transfer pursuant to Rule 144 under the 1933 Act. Upon the receipt of
such request, the Company shall promptly give written notice to all other record
holders of the Registrable Securities that such registration statement is to be
filed and shall include in such registration statement Registrable Securities
for which it has received written requests within ten (10) days after the
Company gives such written notice. Such other requesting record holders shall be
deemed to have exercised their demand registration right under this Section
11.1(i).

                           (ii) If the Company at any time proposes to register
any of its securities under the 1933 Act for sale to the public, whether for its
own account or for the account of other security holders or both, except with
respect to registration statements on Forms S-4, S-8 or another form not
available for registering the Registrable Securities for sale to the public,
provided the Registrable Securities are not otherwise registered for resale by
the Subscribers or Holder pursuant to an effective registration statement, each
such time it will give at least fifteen (15) days' prior written notice to the
record holder of the Registrable Securities of its intention so to do. Upon the
written request of the holder, received by the Company within ten (10) days
after the giving of any such notice by the Company, to register any of the

                                       12
<PAGE>

Registrable Securities not previously registered, the Company will cause such
Registrable Securities as to which registration shall have been so requested to
be included with the securities to be covered by the registration statement
proposed to be filed by the Company, all to the extent required to permit the
sale or other disposition of the Registrable Securities so registered by the
holder of such Registrable Securities (the "Seller" or "Sellers"). In the event
that any registration pursuant to this Section 11.1(ii) shall be, in whole or in
part, an underwritten public offering of common stock of the Company, the number
of shares of Registrable Securities to be included in such an underwriting may
be reduced by the managing underwriter if and to the extent that the Company and
the underwriter shall reasonably be of the opinion that such inclusion would
adversely affect the marketing of the securities to be sold by the Company
therein; provided, however, that the Company shall notify the Seller in writing
of any such reduction. Notwithstanding the foregoing provisions, or Section 11.4
hereof, the Company may withdraw or delay or suffer a delay of any registration
statement referred to in this Section 11.1(ii) without thereby incurring any
liability to the Seller.

                           (iii) If, at the time any written request for
registration is received by the Company pursuant to Section 11.1(i), the Company
has determined to proceed with the actual preparation and filing of a
registration statement under the 1933 Act in connection with the proposed offer
and sale for cash of any of its securities for the Company's own account and the
Company actually does file such other registration statement, such written
request shall be deemed to have been given pursuant to Section 11.1(ii) rather
than Section 11.1(i), and the rights of the holders of Registrable Securities
covered by such written request shall be governed by Section 11.1(ii).

                           (iv) The Company shall file with the Commission not
later than thirty (30) days after the Closing Date (the "Filing Date"), and
cause to be declared effective within one hundred and twenty (120) days after
the Closing Date (the "Effective Date"), a Form SB-2 registration statement (the
"Registration Statement") (or such other form that it is eligible to use) in
order to register the Registrable Securities for resale and distribution under
the 1933 Act. The Company will register not less than a number of shares of
common stock in the aforedescribed registration statement that is equal to all
of the Shares and Warrant Shares issuable pursuant to this Agreement. The
Registrable Securities shall be reserved and set aside exclusively for the
benefit of each Subscriber and Warrant holder, pro rata, and not issued,
employed or reserved for anyone other than each such Subscriber and Warrant
holder. The Registration Statement will immediately be amended or additional
registration statements will be immediately filed by the Company as necessary to
register additional shares of Common Stock to allow the public resale of all
Common Stock included in and issuable by virtue of the Registrable Securities.
Without the written consent of the Subscriber, no securities of the Company
other than the Registrable Securities will be included in the Registration
Statement except as disclosed on Schedule 11.1.

                  11.2. Registration Procedures. If and whenever the Company is
required by the provisions of Section 11.1(i), 11.1(ii), or (iv) to effect the
registration of any Registrable Securities under the 1933 Act, the Company will,
as expeditiously as possible:

                           (a) subject to the timelines provided in this
Agreement, prepare and file with the Commission a registration statement
required by Section 11, with respect to such securities and use its best efforts
to cause such registration statement to become and remain effective for the
period of the distribution contemplated thereby (determined as herein provided),
and promptly provide to the holders of Registrable Securities copies of all
filings and Commission letters of comment;

                           (b) prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement effective until such registration statement has been effective for a
period of two (2) years, and comply with the provisions of the 1933 Act with

                                       13
<PAGE>

respect to the disposition of all of the Registrable Securities covered by such
registration statement in accordance with the Sellers' intended method of
disposition set forth in such registration statement for such period;

                           (c) furnish to the Sellers, at the Company's expense,
such number of copies of the registration statement and the prospectus included
therein (including each preliminary prospectus) as such persons reasonably may
request in order to facilitate the public sale or their disposition of the
securities covered by such registration statement;

                           (d) use its best efforts to register or qualify the
Sellers' Registrable Securities covered by such registration statement under the
securities or "blue sky" laws of such jurisdictions as the Sellers shall request
in writing, provided, however, that the Company shall not for any such purpose
be required to qualify generally to transact business as a foreign corporation
in any jurisdiction where it is not so qualified or to consent to general
service of process in any such jurisdiction;

                           (e) if applicable, list the Registrable Securities
covered by such registration statement with any securities exchange on which the
Common Stock of the Company is then listed;

                           (f) immediately notify the Sellers when a prospectus
relating thereto is required to be delivered under the 1933 Act, of the
happening of any event of which the Company has knowledge as a result of which
the prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing; and

                           (g) provided same would not be in violation of the
provision of Regulation FD under the 1934 Act, make available for inspection by
the Sellers, and any attorney, accountant or other agent retained by the Seller
or underwriter, all publicly available, non-confidential financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all publicly
available, non-confidential information reasonably requested by the seller,
attorney, accountant or agent in connection with such registration statement.

                  11.3. Provision of Documents. In connection with each
registration described in this Section 11, each Seller will furnish to the
Company in writing such information and representation letters with respect to
itself and the proposed distribution by it as reasonably shall be necessary in
order to assure compliance with federal and applicable state securities laws.

                  11.4. Non-Registration Events. The Company and the Subscribers
agree that the Sellers will suffer damages if the Registration Statement is not
filed by the Filing Date and not declared effective by the Commission by the
Effective Date, and any registration statement required under Section 11.1(i) or
11.1(ii) is not filed within 60 days after written request and declared
effective by the Commission within 120 days after such request, and maintained
in the manner and within the time periods contemplated by Section 11 hereof, and
it would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or before the
Filing Date or is not declared effective on or before the sooner of the
Effective Date, or within three (3) business days of receipt by the Company of a
written or oral communication from the Commission that the Registration
Statement will not be reviewed, (ii) if the registration statement described in
Sections 11.1(i) or 11.1(ii) is not filed within 60 days after such written
request, or is not declared effective within 120 days after such written
request, or (iii) any registration statement described in Sections 11.1(i),
11.1(ii) or 11.1(iv) is filed and declared effective but shall thereafter cease
to be effective (without being succeeded within ten (10) business days by an
effective replacement or amended registration statement) for a period of time

                                       14
<PAGE>

which shall exceed 30 days in the aggregate per year (defined as a period of 365
days commencing on the date the Registration Statement is declared effective) or
more than 20 consecutive days (each such event referred to in clauses (i), (ii)
and (iii) of this Section 11.4 is referred to herein as a "Non-Registration
Event"), then the Company shall deliver to the holder of Registrable Securities,
as Liquidated Damages, an amount equal to one percent (1%) for each thirty days
or part thereof of the Purchase Price of the Shares and actually paid "Purchase
Price" (as defined in the Warrants) of Warrant Shares issued or issuable upon
actual exercise of the Warrants, for the Registrable Securities owned of record
by such holder as of and during the pendency of such Non-Registration Event
which are subject to such Non-Registration Event. The Company must pay the
Liquidated Damages in cash within ten (10) days after the end of each thirty
(30) day period or shorter part thereof for which Liquidated Damages are
payable. In the event a Registration Statement is filed by the Filing Date but
is withdrawn prior to being declared effective by the Commission, then such
Registration Statement will be deemed to have not been filed.

                  11.5. Expenses. All expenses incurred by the Company in
complying with Section 11, including, without limitation, all registration and
filing fees, printing expenses, fees and disbursements of counsel and
independent public accountants for the Company, fees and expenses (including
reasonable counsel fees) incurred in connection with complying with state
securities or "blue sky" laws, fees of the National Association of Securities
Dealers, Inc., transfer taxes, fees of transfer agents and registrars, costs of
insurance and fee of one counsel for all Sellers (in an amount not to exceed
$5,000) are called "Registration Expenses." All underwriting discounts and
selling commissions applicable to the sale of Registrable Securities, including
any fees and disbursements of any additional counsel to the Seller, are called
"Selling Expenses." The Company will pay all Registration Expenses in connection
with the registration statement under Section 11. Selling Expenses in connection
with each registration statement under Section 11 shall be borne by the Seller
and may be apportioned among the Sellers in proportion to the number of shares
sold by the Seller relative to the number of shares sold under such registration
statement or as all Sellers thereunder may agree.

                  11.6. Indemnification and Contribution.

                           (a) In the event of a registration of any Registrable
Securities under the 1933 Act pursuant to Section 11, the Company will, to the
extent permitted by law, indemnify and hold harmless the Seller, each officer of
the Seller, each director of the Seller, each underwriter of such Registrable
Securities thereunder and each other person, if any, who controls such Seller or
underwriter within the meaning of the 1933 Act, against any losses, claims,
damages or liabilities, joint or several, to which the Seller, or such
underwriter or controlling person may become subject under the 1933 Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such Registrable Securities was registered under the 1933 Act
pursuant to Section 11, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading
in light of the circumstances when made, and will subject to the provisions of
Section 11.6(c) reimburse the Seller, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company shall not be liable to
the Seller to the extent that any such damages arise out of or are based upon an
untrue statement or omission made in any preliminary prospectus if (i) the
Seller failed to send or deliver a copy of the final prospectus delivered by the
Company to the Seller with or prior to the delivery of written confirmation of
the sale by the Seller to the person asserting the claim from which such damages
arise, (ii) the final prospectus would have corrected such untrue statement or
alleged untrue statement or such omission or alleged omission, or (iii) to the

                                       15
<PAGE>

extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished by any such Seller, or
any such controlling person in writing specifically for use in such registration
statement or prospectus.

                           (b) In the event of a registration of any of the
Registrable Securities under the 1933 Act pursuant to Section 11, each Seller
severally but not jointly will, to the extent permitted by law, indemnify and
hold harmless the Company, and each person, if any, who controls the Company
within the meaning of the 1933 Act, each officer of the Company who signs the
registration statement, each director of the Company, each underwriter and each
person who controls any underwriter within the meaning of the 1933 Act, against
all losses, claims, damages or liabilities, joint or several, to which the
Company or such officer, director, underwriter or controlling person may become
subject under the 1933 Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained
in the registration statement under which such Registrable Securities were
registered under the 1933 Act pursuant to Section 11, any preliminary prospectus
or final prospectus contained therein, or any amendment or supplement thereof,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse the Company and each such
officer, director, underwriter and controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, provided, however,
that the Seller will be liable hereunder in any such case if and only to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information pertaining to
such Seller, as such, furnished in writing to the Company by such Seller
specifically for use in such registration statement or prospectus, and provided,
further, however, that the liability of the Seller hereunder shall be limited to
the net proceeds actually received by the Seller from the sale of Registrable
Securities covered by such registration statement.

                           (c) Promptly after receipt by an indemnified party
hereunder of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party hereunder, notify the indemnifying party in writing thereof, but the
omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to such indemnified party other than under this
Section 11.6(c) and shall only relieve it from any liability which it may have
to such indemnified party under this Section 11.6(c), except and only if and to
the extent the indemnifying party is prejudiced by such omission. In case any
such action shall be brought against any indemnified party and it shall notify
the indemnifying party of the commencement thereof, the indemnifying party shall
be entitled to participate in and, to the extent it shall wish, to assume and
undertake the defense thereof with counsel satisfactory to such indemnified
party, and, after notice from the indemnifying party to such indemnified party
of its election so to assume and undertake the defense thereof, the indemnifying
party shall not be liable to such indemnified party under this Section 11.6(c)
for any legal expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of investigation
and of liaison with counsel so selected, provided, however, that, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be reasonable defenses available to it which are different from
or additional to those available to the indemnifying party or if the interests
of the indemnified party reasonably may be deemed to conflict with the interests
of the indemnifying party, the indemnified parties, as a group, shall have the
right to select one separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the reasonable
expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the indemnifying party as incurred.

                                       16

                           (d) In order to provide for just and equitable
contribution in the event of joint liability under the 1933 Act in any case in
which either (i) a Seller, or any controlling person of a Seller, makes a claim
for indemnification pursuant to this Section 11.6 but it is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 11.6 provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of the Seller or controlling person of the Seller in circumstances for which
indemnification is not provided under this Section 11.6; then, and in each such
case, the Company and the Seller will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that the Seller is responsible only for the
portion represented by the percentage that the public offering price of its
securities offered by the registration statement bears to the public offering
price of all securities offered by such registration statement, provided,
however, that, in any such case, (y) the Seller will not be required to
contribute any amount in excess of the public offering price of all such
securities offered by it pursuant to such registration statement; and (z) no
person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 10(f) of the 1933 Act) will be entitled to contribution from any person
or entity who was not guilty of such fraudulent misrepresentation.

                  11.7. Delivery of Unlegended Shares.

                           (a) Within three (3) business days (such third
business day, the "Unlegended Shares Delivery Date") after the business day on
which the Company has received (i) a notice that Registrable Securities have
been sold either pursuant to the Registration Statement or Rule 144 under the
1933 Act, (ii) a representation that the prospectus delivery requirements, or
the requirements of Rule 144, as applicable, have been satisfied, and (iii) the
original share certificates representing the shares of Common Stock that have
been sold, and (iv) in the case of sales under Rule 144 customary representation
letters of the Subscriber and Subscriber's broker regarding compliance with the
requirements of Rule 144, the Company at its expense, (y) shall deliver, and
shall cause legal counsel selected by the Company to deliver, to its transfer
agent (with copies to Subscriber) an appropriate instruction and opinion of such
counsel, directing the delivery of shares of Common Stock without any legends
including the legends set forth in Sections 4(e) and 4(f) above, issuable
pursuant to any effective and current registration statement described in
Section 11 of this Agreement or pursuant to Rule 144 under the 1933 Act (the
"Unlegended Shares"); and (z) cause the transmission of the certificates
representing the Unlegended Shares together with a legended certificate
representing the balance of the unsold shares of Common Stock, if any, to the
Subscriber at the address specified in the notice of sale, via express courier,
by electronic transfer or otherwise on or before the Unlegended Shares Delivery
Date. Transfer fees shall be the responsibility of the Seller.

                           (b) In lieu of delivering physical certificates
representing the Unlegended Shares, if the Company's transfer agent is
participating in the Depository Trust Company ("DTC") Fast Automated Securities
Transfer program, upon request of a Subscriber, so long as the certificates
therefor do not bear a legend and the Subscriber is not obligated to return such
certificate for the placement of a legend thereon, the Company shall cause its
transfer agent to electronically transmit the Unlegended Shares by crediting the
account of Subscriber's prime Broker with DTC through its Deposit Withdrawal
Agent Commission system. Such delivery must be made on or before the Unlegended
Shares Delivery Date.

                           (c) The Company understands that a delay in the
delivery of the Unlegended Shares pursuant to Section 11 hereof beyond the
Unlegended Shares Delivery Date could result in economic loss to a Subscriber.
As compensation to a Subscriber for such loss, the Company agrees to pay late
payment fees (as liquidated damages and not as a penalty) to the Subscriber for

                                       17
<PAGE>

late delivery of Unlegended Shares in the amount of $100 per business day after
the Delivery Date for each $10,000 of purchase price of the Unlegended Shares
subject to the delivery default. If during any 360 day period, the Company fails
to deliver Unlegended Shares as required by this Section 11.7 for an aggregate
of thirty (30) days, then each Subscriber or assignee holding Securities subject
to such default may, at its option, require the Company to purchase all or any
portion of the Shares and Warrant Shares subject to such default at a price per
share equal to 130% of the Purchase Price of such Common Stock and Warrant
Shares. The Company shall pay any payments incurred under this Section in
immediately available funds upon demand.

                           (d) In addition to any other rights available to a
Subscriber, if the Company fails to deliver to a Subscriber Unlegended Shares as
required pursuant to this Agreement, within ten (10) calendar days after the
Unlegended Shares Delivery Date and the Subscriber purchases (in an open market
transaction or otherwise) shares of common stock to deliver in satisfaction of a
sale by such Subscriber of the shares of Common Stock which the Subscriber
anticipated receiving from the Company (a "Buy-In"), then the Company shall pay
in cash to the Subscriber (in addition to any remedies available to or elected
by the Subscriber) the amount by which (A) the Subscriber's total purchase price
(including brokerage commissions, if any) for the shares of common stock so
purchased exceeds (B) the aggregate purchase price of the shares of Common Stock
delivered to the Company for reissuance as Unlegended Shares, together with
interest thereon at a rate of 15% per annum, accruing until such amount and any
accrued interest thereon is paid in full (which amount shall be paid as
liquidated damages and not as a penalty). For example, if a Subscriber purchases
shares of Common Stock having a total purchase price of $11,000 to cover a
Buy-In with respect to $10,000 of purchase price of shares of Common Stock
delivered to the Company for reissuance as Unlegended Shares, the Company shall
be required to pay the Subscriber $1,000, plus interest. The Subscriber shall
provide the Company written notice indicating the amounts payable to the
Subscriber in respect of the Buy-In.

                           (e) In the event a Subscriber shall request delivery
of Unlegended Shares as described in Section 11.7(a), the Company may not refuse
to deliver Unlegended Shares based on any claim that such Subscriber or any one
associated or affiliated with such Subscriber has been engaged in any violation
of law, or for any other reason, unless, an injunction or temporary restraining
order from a court, on notice, restraining and or enjoining delivery of such
Unlegended Shares or exercise of all or part of said Warrant shall have been
sought and obtained and the Company has posted a surety bond for the benefit of
such Subscriber in the amount of 130% of the amount of the aggregate purchase
price of the Common Stock and Warrant Shares which are subject to the injunction
or temporary restraining order, which bond shall remain in effect until the
completion of arbitration/litigation of the dispute and the proceeds of which
shall be payable to such Subscriber to the extent Subscriber obtains judgment in
Subscriber's favor.

                  12.      (a) Right of First Refusal. During the Exclusion
Period, the Subscribers shall be given not less than seven (7) business days
prior written notice of any proposed sale by the Company of its common stock or
other securities or debt obligations, except in connection with (i) employee
stock options or compensation plans, (ii) as full or partial consideration in
connection with any merger, consolidation or purchase of substantially all of
the securities or assets of any corporation or other entity, or (iii) as has
been described in the Reports or Other Written Information filed or delivered
prior to the Initial Closing Date (collectively "Excepted Issuances"). The
Subscribers who exercise their rights pursuant to this Section 12(a) shall have
the right during the seven (7) business days following receipt of the notice to
purchase all of such offered common stock, debt or other securities in
accordance with the terms and conditions set forth in the notice of sale in the
same proportion to each other as their purchase of Shares in the Offering. In
the event such terms and conditions are modified during the notice period, the

                                       18
<PAGE>

Subscribers shall be given prompt notice of such modification and shall have the
right during the original notice period or for a period of seven (7) business
days following the notice of modification, whichever is longer, to exercise such
right.

                           (b) Offering Restrictions. During the Exclusion
Period except in connection with the Excepted Issuances or the Offering, the
Company will not enter into any agreement to, nor issue any equity, convertible
debt or other securities convertible into common stock without the prior written
consent of Subscribers holding not less than a majority of the Shares and, if
issued, Warrant Shares, which consent may be withheld for any reason.

                           (c) Favored Nations Provision. At any time during the
Exclusion Period, if the Company shall offer, issue or agree to issue any common
stock or securities convertible into or exercisable for shares of common stock
(or modify any of the foregoing which may be outstanding at any time prior to
the Closing Date) to any person or entity at a price per share or conversion or
exercise price per share which shall be less than the Per Share Purchase Price,
without the consent of each Subscriber holding Shares, then the Company shall
issue, for each such occasion, additional shares of Common Stock to each
Subscriber so that the average Per Share Purchase Price of the shares of Common
Stock issued to the Subscriber (of only the Common Stock or Warrant Shares still
owned by the Subscriber) is equal to such other lower price per share. The
delivery to the Subscriber of the additional shares of Common Stock shall be not
later than the closing date of the transaction giving rise to the requirement to
issue additional shares of Common Stock. The Subscriber is granted the
registration rights described in Section 11 hereof in relation to such
additional shares of Common Stock except that the Filing Date and Effective Date
vis-a-vis such additional common shares shall be, respectively, the sixtieth
(60th) and one hundred and twentieth (120th) date after the closing date giving
rise to the requirement to issue the additional shares of Common Stock. For
purposes of the issuance and adjustment described in this paragraph, the
issuance of any security of the Company carrying the right to convert such
security into shares of Common Stock or of any warrant, right or option to
purchase Common Stock shall result in the issuance of the additional shares of
Common Stock upon the issuance of such convertible security, warrant, right or
option and again upon any subsequent issuances of shares of Common Stock upon
exercise of such conversion or purchase rights if such issuance is at a price
lower than the then Per Share Purchase Price. The rights of the Subscriber set
forth in this Section 12 are in addition to any other rights the Subscriber has
pursuant to this Agreement and any other agreement referred to or entered into
in connection herewith.

                           (d) Maximum Exercise of Rights. In the event the
exercise of the rights described in Sections 12(a) and 12(c) would result in the
issuance of an amount of common stock of the Company that would exceed the
maximum amount that may be issued to a Subscriber calculated in the manner
described in Section 10 of the Warrant, then the issuance of such additional
shares of common stock of the Company to such Subscriber will be deferred in
whole or in part until such time as such Subscriber is able to beneficially own
such common stock without exceeding the maximum amount set forth calculated in
the manner described in Section 10 of the Warrant. The determination of when
such common stock may be issued shall be made by each Subscriber as to only such
Subscriber.

                  13.      Miscellaneous.

                           (a) Notices. All notices, demands, requests,

                           (c) Entire Agreement; Assignment. This Agreement and
other documents delivered in connection herewith represent the entire agreement
between the parties hereto with respect to the subject matter hereof and may be
amended only by a writing executed by both parties. Neither the Company nor the

this Agreement and the documents delivered herewith. No right or obligation of
either party shall be assigned by that party without prior notice to and the
written consent of the other party.

                           (d) Counterparts/Execution. This Agreement may be

federal courts located in the state of New York. THE PARTIES AND THE INDIVIDUALS
EXECUTING THIS AGREEMENT AND OTHER AGREEMENTS REFERRED TO HEREIN OR DELIVERED IN
CONNECTION HEREWITH ON BEHALF OF THE COMPANY AGREE TO SUBMIT TO THE JURISDICTION
OF SUCH COURTS AND WAIVE TRIAL BY JURY. The prevailing party shall be entitled
to recover from the other party its reasonable attorney's fees and costs. In the
event that any provision of this Agreement or any other agreement delivered in
connection herewith is invalid or unenforceable under any applicable statute or
rule of law, then such provision shall be deemed inoperative to the extent that
it may conflict therewith and shall be deemed modified to conform with such
statute or rule of law. Any such provision which may prove invalid or
unenforceable under any law shall not affect the validity or enforceability of
any other provision of any agreement.

                           (f) Specific Enforcement, Consent to Jurisdiction.
The Company and Subscriber acknowledge and agree that irreparable damage would
occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It

                                       20
<PAGE>

is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Agreement and
to enforce specifically the terms and provisions hereof, this being in addition
to any other remedy to which any of them may be entitled by law or equity.
Subject to Section 13(e) hereof, each of the Company, Subscriber and any
signator hereto in his personal capacity hereby waives, and agrees not to assert
in any such suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction in New York of such court, that the suit, action or
proceeding is brought in an inconvenient forum or that the venue of the suit,
action or proceeding is improper. Nothing in this Section shall affect or limit
any right to serve process in any other manner permitted by law.

                           (g) Independent Nature of Subscribers' Obligations
and Rights. The obligations of each Subscriber hereunder are several and not
joint with the obligations of any other Subscriber hereunder, and no such
Subscriber shall be responsible in any way for the performance of the
obligations of any other hereunder.

                           (h) Equitable Adjustment. The Securities and the
purchase prices of Securities shall be equitably adjusted to offset the effect
of stock splits, stock dividends, and distributions of property or equity
interests of the Company to its shareholders.

         1. Exercise of Warrant.

                  1.1. Number of Shares Issuable upon Exercise. From and after
the Issue Date through and including the Expiration Date, the Holder hereof
shall be entitled to receive, upon exercise of this Warrant in whole in
accordance with the terms of subsection 1.2 or upon exercise of this Warrant in
part in accordance with subsection 1.3, shares of Common Stock of the Company,
subject to adjustment pursuant to Section 4.

                  1.2. Full Exercise. This Warrant may be exercised in full by
the Holder hereof by delivery of an original or facsimile copy of the form of
subscription attached as Exhibit A hereto (the "Subscription Form") duly
executed by such Holder and surrender of the original Warrant within seven (7)
days of exercise, to the Company at its principal office or at the office of its
Warrant Agent (as provided hereinafter), accompanied by payment, in cash, wire
transfer or by certified or official bank check payable to the order of the
Company, in the amount obtained by multiplying the number of shares of Common
Stock for which this Warrant is then exercisable by the Purchase Price then in
effect.

                  1.3. Partial Exercise. This Warrant may be exercised in part
(but not for a fractional share) by surrender of this Warrant in the manner and
at the place provided in subsection 1.2 except that the amount payable by the
Holder on such partial exercise shall be the amount obtained by multiplying (a)
the number of whole shares of Common Stock designated by the Holder in the
Subscription Form by (b) the Purchase Price then in effect. On any such partial
exercise, the Company, at its expense, will forthwith issue and deliver to or
upon the order of the Holder hereof a new Warrant of like tenor, in the name of
the Holder hereof or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may request, the whole number of shares of Common
Stock for which such Warrant may still be exercised.

                  1.4. Fair Market Value. Fair Market Value of a share of Common
Stock as of a particular date (the "Determination Date") shall mean:

                           (a) If the Company's Common Stock is traded on an
exchange or is quoted on the National Association of Securities Dealers, Inc.
Automated Quotation ("NASDAQ"), National Market System, the NASDAQ SmallCap
Market or the American Stock Exchange, LLC, then the closing or last sale price,
respectively, reported for the last business day immediately preceding the
Determination Date;

                           (b) If the Company's Common Stock is not traded on an
exchange or on the NASDAQ National Market System, the NASDAQ SmallCap Market or
the American Stock Exchange, Inc., but is traded in the over-the-counter market,
then the average of the closing bid and ask prices reported for the last
business day immediately preceding the Determination Date;

                           (c) Except as provided in clause (d) below, if the
Company's Common Stock is not publicly traded, then as the Holder and the
Company agree, or in the absence of such an agreement, by arbitration in
accordance with the rules then standing of the American Arbitration Association,
before a single arbitrator to be chosen from a panel of persons qualified by
education and training to pass on the matter to be decided; or

                           (d) If the Determination Date is the date of a
liquidation, dissolution or winding up, or any event deemed to be a liquidation,
dissolution or winding up pursuant to the Company's charter, then all amounts to
be payable per share to holders of the Common Stock pursuant to the charter in
the event of such liquidation, dissolution or winding up, plus all other amounts
to be payable per share

                                       2
<PAGE>

in respect of the Common Stock in liquidation under the charter, assuming for
the purposes of this clause (d) that all of the shares of Common Stock then
issuable upon exercise of all of the Warrants are outstanding at the
Determination Date.

                  1.5. Company Acknowledgment. The Company will, at the time of
the exercise of the Warrant, upon the request of the Holder hereof acknowledge
in writing its continuing obligation to afford to such Holder any rights to
which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of this Warrant. If the Holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford to such Holder any such rights.

                  1.6. Trustee for Warrant Holders. In the event that a bank or
trust company shall have been appointed as trustee for the Holder of the
Warrants pursuant to Subsection 3.2, such bank or trust company shall have all
the powers and duties of a warrant agent (as hereinafter described) and shall
accept, in its own name for the account of the Company or such successor person
as may be entitled thereto, all amounts otherwise payable to the Company or such
successor, as the case may be, on exercise of this Warrant pursuant to this
Section 1.

                  1.7 Delivery of Stock Certificates, etc. on Exercise. The
Company agrees that the shares of Common Stock purchased upon exercise of this
Warrant shall be deemed to be issued to the Holder hereof as the record owner of
such shares as of the close of business on the date on which this Warrant shall
have been surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within five (5) days thereafter, the Company at its expense (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and delivered to the Holder hereof, or as such Holder (upon payment by such
Holder of any applicable transfer taxes) may direct in compliance with
applicable securities laws, a certificate or certificates for the number of duly
and validly issued, fully paid and nonassessable shares of Common Stock (or
Other Securities) to which such Holder shall be entitled on such exercise, plus,
in lieu of any fractional share to which such Holder would otherwise be
entitled, cash equal to such fraction multiplied by the then Fair Market Value
of one full share of Common Stock, together with any other stock or other
securities and property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 1 or otherwise.

          2.      Cashless Exercise.

                  (a) If a Registration Statement as defined in the Subscription
Agreement ("Registration Statement") is effective and the Holder may sell its
shares of Common Stock upon exercise hereof, this Warrant may be exercisable in
whole or in part for cash only as set forth in Section 1 above. If no such
Registration Statement is available, payment upon exercise may be made at the
option of the Holder either in (i) cash, wire transfer or by certified or
official bank check payable to the order of the Company equal to the applicable
aggregate Purchase Price, (ii) by delivery of Common Stock issuable upon
exercise of the Warrants in accordance with Section (b) below or (iii) by a
combination of any of the foregoing methods, for the number of Common Stock
specified in such form (as such exercise number shall be adjusted to reflect any
adjustment in the total number of shares of Common Stock issuable to the holder
per the terms of this Warrant) and the holder shall thereupon be entitled to
receive the number of duly authorized, validly issued, fully-paid and
non-assessable shares of Common Stock (or Other Securities) determined as
provided herein.

                  (b) Notwithstanding any provisions herein to the contrary, if
the Fair Market Value of one share of Common Stock is greater than the Purchase
Price (at the date of calculation as set forth below), in lieu of exercising
this Warrant for cash, the holder may elect to receive shares equal to the

                                       3
<PAGE>

value (as determined below) of this Warrant (or the portion thereof being
cancelled) by surrender of this Warrant at the principal office of the Company
together with the properly endorsed Subscription Form in which event the Company
shall issue to the holder a number of shares of Common Stock computed using the
following formula:

                           X = Y (A-B)
                               -------
                                  A

                  Where    X =      the number of shares of Common Stock to be
                                    issued to the holder

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

                           A =      the Fair Market Value of one share of the
                                    Company's Common Stock (at the date of such
                                    calculation)

                           B =      Purchase Price (as adjusted to the date of
                                    such calculation)

                  (c) The Holder may employ the cashless exercise feature
described above only during the pendency of a Non-Registration Event as
described in Section 11.4 of the Subscription Agreement.

                  (d) For purposes of Rule 144 promulgated under the 1933 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
Subscription Agreement.

         3.       Adjustment for Reorganization, Consolidation, Merger, etc.

                  3.1. Reorganization, Consolidation, Merger, etc. In case at
any time or from time to time, the Company shall (a) effect a reorganization,
(b) consolidate with or merge into any other person or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1, at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto, all subject to
further adjustment thereafter as provided in Section 4.

                  3.2. Dissolution. In the event of any dissolution of the
Company following the transfer of all or substantially all of its properties or
assets, the Company, prior to such dissolution, shall at its expense deliver or
cause to be delivered the stock and other securities and property (including
cash, where applicable) receivable by the Holder of the Warrants after the
effective date of such dissolution pursuant to this Section 3 to a bank or trust
company (a "Trustee") having its principal office in New York, NY, as trustee
for the Holder of the Warrants.

                                       4
<PAGE>

                  3.3. Continuation of Terms. Upon any reorganization,
consolidation, merger or transfer (and any dissolution following any transfer)
referred to in this Section 3, this Warrant shall continue in full force and
effect and the terms hereof shall be applicable to the Other Securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any Other Securities, including, in the case of any
such transfer, the person acquiring all or substantially all of the properties
or assets of the Company, whether or not such person shall have expressly
assumed the terms of this Warrant as provided in Section 4. In the event this
Warrant does not continue in full force and effect after the consummation of the
transaction described in this Section 3, then only in such event will the
Company's securities and property (including cash, where applicable) receivable
by the Holder of the Warrants be delivered to the Trustee as contemplated by
Section 3.2.

                  3.4 Share Issuance. Until the Expiration Date, if the Company
shall issue any Common Stock except for the Excepted Issuances (as defined in
the Subscription Agreement), prior to the complete exercise of this Warrant for
a consideration less than the Purchase Price that would be in effect at the time
of such issue, then, and thereafter successively upon each such issue, the
Purchase Price shall be reduced to such other lower issue price. For purposes of
this adjustment, the issuance of any security or debt instrument of the Company
carrying the right to convert such security or debt instrument into Common Stock
or of any warrant, right or option to purchase Common Stock shall result in an
adjustment to the Purchase Price upon the issuance of the above-described
security, debt instrument, warrant, right, or option. The reduction of the
Purchase Price described in this Section 3.4 is in addition to the other rights
of the Holder described in the Subscription Agreement.

         4. Extraordinary Events Regarding Common Stock. In the event that the
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the Holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be adjusted to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Purchase Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Purchase Price in effect
on the date of such exercise.

         5. Certificate as to Adjustments. In each case of any adjustment or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the Warrants, the Company at its expense will promptly cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or readjustment in accordance with the terms of the Warrant and prepare a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based, including a
statement of (a) the consideration received or receivable by the Company for any
additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold, (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding, and (c) the Purchase Price
and the number of shares of Common Stock to be

                                       5
<PAGE>

received upon exercise of this Warrant, in effect immediately prior to such
adjustment or readjustment and as adjusted or readjusted as provided in this
Warrant. The Company will forthwith mail a copy of each such certificate to the
Holder of the Warrant and any Warrant Agent of the Company (appointed pursuant
to Section 11 hereof).

         6. Reservation of Stock, etc. Issuable on Exercise of Warrant;
Financial Statements. The Company will at all times reserve and keep available,
solely for issuance and delivery on the exercise of the Warrants, all shares of
Common Stock (or Other Securities) from time to time issuable on the exercise of
the Warrant. This Warrant entitles the Holder hereof to receive copies of all
financial and other information distributed or required to be distributed to the
holders of the Company's Common Stock.

         7. Assignment; Exchange of Warrant. Subject to compliance with
applicable securities laws, this Warrant, and the rights evidenced hereby, may
be transferred by any registered holder hereof (a "Transferor"). On the
surrender for exchange of this Warrant, with the Transferor's endorsement in the
form of Exhibit B attached hereto (the "Transferor Endorsement Form") and
together with an opinion of counsel reasonably satisfactory to the Company that
the transfer of this Warrant will be in compliance with applicable securities
laws, the Company at its expense, twice, only, but with payment by the
Transferor of any applicable transfer taxes, will issue and deliver to or on the
order of the Transferor thereof a new Warrant or Warrants of like tenor, in the
name of the Transferor and/or the transferee(s) specified in such Transferor
Endorsement Form (each a "Transferee"), calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock called for on the face or
faces of the Warrant so surrendered by the Transferor. No such transfers shall
result in a public distribution of the Warrant; and the Company shall only be
responsible for "blue sky" compliance expenses for resales under any
registration statement filed in accordance with Section 11 of the Subscription
Agreement for two (2) such transfers to two (2) applicable states of the United
States only.

         8. Replacement of Warrant. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense, twice only, will execute and deliver, in lieu thereof, a new Warrant of
like tenor.

         9. Registration Rights. The Holder of this Warrant has been granted
certain registration rights by the Company. These registration rights are set
forth in the Subscription Agreement. The terms of the Subscription Agreement are
incorporated herein by this reference. During the pendency of a Non-Registration
Event (as defined in the Subscription Agreement, upon written demand made by the
Holder, the Company will pay to the Holder of this Warrant, in lieu of
delivering Common Stock, a sum equal to the closing price of the Company's
Common Stock on the principal market or exchange upon which the Common Stock is
listed for trading on the trading date immediately preceding the date notice is
given by the Holder, less the Purchase Price, for each share of Common Stock
designated in such notice from the Holder.

         10. Maximum Exercise. The Holder shall not be entitled to exercise this
Warrant on an exercise date nor may the Company exercise its right to give a
Call Notice (as defined in Section 11) in connection with that number of Common
Stock which would be in excess of the sum of (i) the number of Common Stock
beneficially owned by the Holder and its affiliates on an exercise date or Call
Date, and (ii) the number of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this limitation is being made
on an exercise date or Call Date, which would result in beneficial ownership by
the Holder and its affiliates of more than 4.99% of the outstanding Common

                                       6
<PAGE>

Stock on such date. For the purposes of the immediately preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder.
Subject to the foregoing, the Holder shall not be limited to aggregate exercises
which would result in the issuance of more than 4.99%. The restriction described
in this paragraph may be revoked upon sixty-one (61) days prior notice from the
Holder to the Company. The Holder may allocate which of the equity of the
Company deemed beneficially owned by the Subscriber shall be included in the
4.99% amount described above and which shall be allocated to the excess above
4.99%.

         11. Call. The Company shall have the option to "call" the Warrants (the
"Warrant Call"), one or more times, in accordance with and governed by the
following:

                  (a) The Company shall exercise the Warrant Call by giving to
the Warrant Holder a written notice of call (the "Call Notice") during the
period in which the Warrant Call may be exercised. The effective date of each
Call Notice (the "Call Date") is the date on which notice is effective under the
notice provision of Section 13 of this Warrant.

                  (b) The Company's right to exercise the Warrant Call shall
commence thirty trading days after the actual effective date of a registration
statement described in Section 11.1(iv) of the Subscription Agreement and end
thirty trading days prior to the Expiration Date.

                  (c) The number of shares of Common Stock to be issued upon
exercise of the Warrant which are subject to a Call Notice must be registered in
a registration statement effective from twenty-two trading days prior to the
Call Date and through the Delivery Date.

                  (d) A Call Notice may be given not sooner than fifteen trading
days after the prior Call Date.

                  (e) A Call Notice may be given by the Company only within five
trading days after the Common Stock has had a closing price as reported for the
Principal Market (as defined in the Subscription Agreement) of not less than two
hundred percent (200%) of the Purchase Price for fifteen (15) consecutive
trading days ("Lookback Period").

                  (f) The Common Stock must be listed on the Principal Market
for the Lookback Period and through the Delivery Date.

                  (g) The Company shall not have received a notice from the
Principal Market during the ninety calendar days prior to the Call Date that the
Company or the Common Stock does not meet the requirements for continued
quotation, listing or trading on the Principal Market.

                  (h) The Company and the Common Stock shall meet the
requirements for continued quotation, listing or trading on the Principal Market
for the Lookback Period and through the Delivery Date.

                  (i) Unless otherwise agreed to by the Holder of this Warrant,
a Call Notice must be given to all Warrant Holders who receive Warrants similar
to this Warrant (in terms of exercise price and other principal terms) issued on
or about the same Issue Date as this Warrant, in proportion to the amounts of
Common Stock which may be purchased by the respective Warrant Holders in
accordance with the respective Warrants held by each.

                                       7
<PAGE>

                  (j) The Warrant Holder shall exercise his Warrant rights and
purchase the Called Common Stock and pay for same within fourteen trading days
after the Call Date. If the Warrant Holder fails to timely pay the amount
required by the Warrant Call, the Company's sole remedy shall be to cancel a
corresponding amount of this Warrant.

                  (k) The Company may not exercise the right to Call this
Warrant after the occurrence of a default by the Company of a material term of
this Warrant or the Subscription Agreement.

         12. Warrant Agent. The Company may, by written notice to the Holder of
the Warrant, appoint an agent (a "Warrant Agent") for the purpose of issuing
Common Stock (or Other Securities) on the exercise of this Warrant pursuant to
Section 1, exchanging this Warrant pursuant to Section 7, and replacing this
Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such
