     The shares of Common Stock ("Shares" or "Securities") of the Company, as
well as the terms of the Offering, which are described in the Memorandum, are
being offered without registration under the Securities Act of 1933, as amended
(the "Act"), or the securities laws of any state or any other jurisdiction, in
reliance on the exemption contained in Section 4(2) of the Act and Regulation D
promulgated thereunder and on similar exemptions under applicable state laws.
Under Regulation D of the Act and/or certain state laws, the Company is required
to determine that an individual, or an individual together with a "purchaser
representative" or each individual equity owner of an "investing entity" meets
certain suitability requirements before selling Securities to such individual or
entity. You understand that the Company will rely upon the following information
to determine whether you meet such suitability requirements.

     THE COMPANY WILL NOT SELL SECURITIES TO ANY SUBSCRIBER WHO HAS NOT FILLED
OUT, AS THOROUGHLY AS POSSIBLE, EXECUTED AND DELIVERED THIS QUESTIONNAIRE. IN
THE CASE OF A SUBSCRIBER THAT IS A PARTNERSHIP, TRUST, CORPORATION OR OTHER
ENTITY, AN AUTHORIZED OFFICER, OR GENERAL PARTNER OR EACH EQUITY OWNER OR
BENEFICIARY, AS APPLICABLE, MUST COMPLETE THIS QUESTIONNAIRE. This questionnaire
is merely a request for information and does not constitute an offer to sell or
a solicitation of an offer to buy the Shares. No sale will occur prior to the
acceptance of any subscription by the Company and the Placement Agent. The
Company and First Montauk Securities Corp., as Placement Agent, reserve the
right to reject any subscription for any reason or to accept subscriptions for
less than the minimum subscription of $80,000 (20,000 shares). The Company and
First Montauk Securities Corp. will promptly return any money without interest
to a subscriber whose subscription is rejected in whole or in part as the case
may be. Subscribers should also understand that they may be required to furnish
additional information to the Company.

     The Shares are being offered by the Company through First Montauk
Securities Corp., as Placement Agent. The purpose of this Questionnaire is to
determine whether you meet certain standards, because the Shares will not be
registered under the Act and will be sold only to persons who are "Accredited
Investors," as that term is defined in Rule 501(a) of Regulation D, promulgated
under the Act. The Shares are sometimes referred to as the "Securities."

     Your answers will be kept confidential. At all times, however, you hereby
agree that the Company may present this Questionnaire to such parties as it
deems appropriate in order to assure itself that the offer and the sale of the
Shares to you will not result in violations of federal or state securities laws
which are being relied upon by the Company in connection with the offer and sale
thereof and as otherwise required by law or any regulatory authority.

     Please type or clearly print your answers, and state "none" or "not
applicable" when appropriate. Please complete Section A and each other section
you are requested to complete in Question A3. If there is insufficient space for
any of your answers, please attach additional pages. If the Shares are to be
owned by more than one individual or by a corporation or partnership, you may
need extra copies of this Questionnaire. You may use photocopies or request
extra copies from the Company or the Placement Agent.

SECTION G: REPRESENTATIONS AND WARRANTIES BY ALL SUBSCRIBERS

     By signing this Questionnaire, the undersigned hereby confirms the
following statements:

     (a) I have read the Confidential Private Placement Memorandum and this
Subscription Agreement and other accompanying documents of the Company, and am
aware of and understand the risk factors disclosed therein related to the
Company and an investment in the Company.

     (b) I am aware that the offering of the Shares involves securities for
which no market exists, thereby requiring any investment to be maintained for an
indefinite period of time. The Company is not a reporting company under the
Securities and Exchange Act of 1934, and therefore does not file periodic
reports with the SEC.

     (c) I acknowledge that any delivery to me of the Confidential Private
Placement Memorandum relating to the Shares prior to the determination by the
Company of my suitability as an Subscriber shall not constitute an offer of the
Shares until such determination of suitability shall be made, and I agree that I
shall promptly return the Confidential Private Placement Memorandum and the
other Offering Documents to the Company upon request.

     (d) I also understand and agree that, although the Company and the
Placement Agent will use their respective best efforts to keep the information
provided in answers to this Questionnaire strictly confidential, the Company and
the Placement Agent or their respective counsel may present this Questionnaire
and the information provided in answer to it to such parties as they may deem
advisable if called upon to establish the availability under any federal or
state securities laws of an exemption from registration of the private placement
or if the contents thereof are relevant to any issue in any action, suit or
proceeding to which the Company, the Placement Agent or their respective
affiliates is a party, or by which they are or may be bound or as otherwise
required by law or regulatory authority.

     (e) I realize that this Questionnaire does not constitute an offer to sell
or a solicitation of an offer to buy the Shares or any other security of the
Company but is merely a request for information.

     (f) I understand that the Shares are being offered without registration
under the Securities Act in reliance upon the private offering exemption
contained therein, and that such reliance is based in part on the information
herein supplied. For the foregoing reasons and to induce the Company to issue
and deliver the Securities to me, I represent and warrant that the information
stated herein is true, accurate and complete, and I agree to notify and supply
corrective information promptly to the Company as provided above if any of such
information becomes inaccurate or incomplete.

     (g) The individual signing below on behalf of any entity hereby warrants
and represents that he/she is authorized to execute this questionnaire on behalf
of such entity.


                                       20

          (ii) The Securities may not be resold by the Subscriber in the absence
of a registration under the Act or exemption from registration. In particular,
the Subscriber is aware that the Securities will be "restricted securities", as
such term is defined in Rule 144 promulgated under the Securities Act ("Rule
144"), and they may not be sold pursuant to Rule 144, unless the conditions
thereof are met.

          (iii) The following legends (or similar language) shall be placed on
the certificate(s) evidencing the Securities:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933 (THE "ACT"), OR ANY STATE SECURITIES LAWS
     AND NEITHER SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD,

     IN ACCORDANCE WITH SUCH AGREEMENT. COPIES OF SUCH AGREEMENT ARE ON FILE IN
     THE OFFICE OF THE CORPORATION AND WILL BE MADE AVAILABLE FOR INSPECTION TO
     ANY PROPERLY INTERESTED PERSON WITHOUT CHARGE UPON WRITTEN REQUEST.

          (iv) The Company may at any time place a stop transfer order on its
transfer books against the Securities. Such stop order will be removed, and
further transfer of the Securities will be permitted upon an effective
registration of the respective Securities, or the receipt by the Company of an
opinion of counsel satisfactory to the Company that such further transfer may be
effected pursuant to an applicable exemption from registration.

          (v) The purchase of the Securities involves risks which the Subscriber
has evaluated, and the Subscriber is able to bear the economic risk of the
purchase of such securities and the loss of its entire investment.

     (l) The Subscriber agrees to indemnify and hold harmless the Company, the
officers, directors, employees, agents, counsel and affiliates of the Company,
and each other person, if any, who controls the Company, within the meaning of
Section 15 of the Act or Section 20 of the Securities and Exchange Act of 1934,
as amended, against any and all losses, liabilities, claims, damages and all
expenses reasonably incurred in investigating, preparing or defending against
any litigation commenced or threatened or any claim whatsoever arising out of or
based upon any false representation or warranty or breach or failure by the
Subscriber to comply with any covenant or agreement made by the Subscriber
herein or in any other document furnished by the Subscriber to any of the
foregoing in connection with this transaction.

     (m) The Subscriber hereby acknowledges and agrees, subject to any
applicable state securities laws that the subscription and application hereunder
are irrevocable, that the Subscriber is not entitled to cancel, terminate or
revoke this Subscription Agreement and that this Subscription Agreement shall
survive the death or disability of the Subscriber and shall be binding upon and
inure to the benefit of the Subscriber and his heirs, executors, administrators,
successors, legal representatives, and assigns. If the Subscriber is more than
one person, the obligations of the Subscriber hereunder shall be joint and
several, and the agreements, representations, warranties, and acknowledgments
herein contained shall be deemed to be made by and be binding upon each such
person and his heirs, executors, administrators, successors, legal
representatives, and assigns.

     (n) The Company and the Placement Agent have each employed its own legal
counsel in connection with the Offering. The Subscribers have not been
represented by independent counsel in connection with the preparation of the
Memorandum or the terms of this Offering and no investigation of the merits or
fairness of the Offering has been conducted on


                                       22

SECTION H: OTHER COVENANTS AND AGREEMENTS

     (A)  REGISTRATION RIGHTS.

     The Subscriber and the Company agree that the Subscriber shall be entitled
to the registration rights with respect to the Shares as set forth in this
Section H (a).

     (i) Definition of Registrable Securities. As used herein the term
"Registrable Security" means each Share issued in the Offering and any
securities issued upon any stock split or stock dividend in respect thereof;
provided, however, that with respect to any particular Registrable Security,
such security shall cease to be a Registrable Security when, as of the date of
determination; (A) it has been effectively registered under the Act; (B)
registration under the Act is no longer required for subsequent public
distribution of such security; or (B) it has ceased to be outstanding. The term
"Registrable Securities" means any and/or all of the securities falling within
the foregoing definition of a "Registrable Security." In the event of any
merger, reorganization, consolidation, recapitalization or other change in
corporate structure affecting the Common Stock, such adjustment shall be made in
the definition of "Registrable Security" as is appropriate in order to prevent
any dilution or increase of the rights granted pursuant to this Clause (a) as
determined in good faith by the Board of Directors;

     (ii) Registration by the Company. The first time after the date hereof that
the Company files a registration statement under the Act not on Form S-8, S-4 or
another inappropriate form with the Securities and Exchange Commission to
register for sale any of its shares of Common Stock, the Company will include
for resale under the Act in the registration statement the Registrable
Securities. The Company shall not be required to register for resale any
Registrable Securities if at the time of such proposed registration, the
Registrable Securities may be sold without any limitation under Rule 144.
Notwithstanding the foregoing, if the registration statement filed by the
Company is pursuant to an underwritten offering:

          (A) if the underwriter determines in good faith that marketing factors
require the exclusion of all shares held by existing stockholders, no
Registrable Securities shall be included in such registration and the right to
have Registrable Securities included in the first registration statement filed
by the Company shall be deferred to the second registration statement filed by
the Company, which deferral may be continued to the third or subsequent
registration statement so long as the registration statements are pursuant to
underwritten offerings and the underwriter determines in good faith that
marketing factors require exclusion of all shares held by existing stockholders;

          (B) each holder of Registrable Securities ("Holder") shall enter into
an underwriting agreement in customary form with the underwriter and provide
such information regarding Holder that the underwriter shall reasonably request
in connection with the preparation of the prospectus describing such offering,
including completion of NASD Questionnaires; and

          (C) each Holder hereby agrees that such Holder shall not sell,
transfer, make any short sale of, grant any option for the purchase of, or enter
into any hedging or similar transaction with the same economic effect as a sale,
any Registrable Securities for a period


                                       24

<PAGE>

specified by the underwriter not to exceed one hundred eighty (180) days
following the effective date of the registration statement, or such lesser
period equal to the lockup period required of the Company's officers and
directors and other shareholders. The Company may impose stop-transfer
instructions with respect to Registrable Securities subject to the foregoing
restriction until the end of said lock-up period. Each Holder agrees that any
transferee of any Registrable Securities shall be bound by this lock-up
agreement and certificates evidencing the Registrable Securities shall include a
legend reflecting this agreement (see above).

     (iii) Covenants of the Company With Respect to Registration. In connection
with the registration in which the Registrable Securities are included, the
Company covenants and agrees as follows:

          (A) The Company shall use its commercially reasonable efforts to have
the registration statement declared effective as soon as possible after filing,
and shall furnish each Holder of Registrable Securities such number of
prospectuses as shall reasonably be requested. In addition, the Company shall
file such amendments as may be required from time to time, in order to keep any
registration statement filed under this Clause (a) effective as provided herein.
The registration statement filed by the Company hereunder shall remain effective
for the earlier of (i) 9 months or (ii) the date that the Registrable Securities
may be sold without volume limitation under SEC Rule 144(k).

          (B) The Company shall pay all costs (excluding fees and expenses of
Holder(s) counsel and any underwriting or selling discounts or commissions),
fees and expenses in connection with the registration statement filed pursuant
hereto including, without limitation, the Company's legal and accounting fees,
printing expenses, blue sky fees and expenses.

          (C) The Company will take all necessary action which may be required
in qualifying or registering the Registrable Securities included in the
registration statement, for offering and sale under the securities or blue sky
laws of such states as reasonably are requested by the Holder(s), provided that
the Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business under
the laws of any such jurisdiction.

          (D) The Company shall indemnify each Holder of Registrable Securities
to be sold pursuant to the registration statement and each person, if any, who
controls such Holder within the meaning of Section 15 of the Act or Section
20(a) of the Securities Exchange Act of 1934, as amended ("Exchange Act"),
against all loss, claim, damage, expense or liability (including all reasonable
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement, except to
the extent arising under paragraph (E) below.

          (E) Each Holder of Registrable Securities to be sold pursuant to a
registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, its officers and directors and any
underwriter, and each person, if any, who controls the Company or such
underwriter within the meaning of Section 15 of the Act or Section 20(a)


                                       25

<PAGE>

of the Exchange Act, against all loss, claim, damage or reasonable expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising (I) from
information furnished by or on behalf of such Holder, or their successors or
assigns, for specific inclusion in such registration statement or (II) as a
result of use by the Holder of a registration statement that the Holder was
advised to discontinue; provided, however, that in no event shall any indemnity
hereunder exceed the net proceeds from the offering received by such Holder.

     (B) ANTI- DILUTION PROTECTION.

     (i) Unless waived by the Placement Agent on behalf of all investors in the
Offering, during the period commencing on the date hereof and ending upon the
earlier of (A) a date which is three years following the Final Closing Date of
the Offering or (B) the date which is one day prior to the effective date of an
initial public offering, if the Company sells or issues additional shares of
Common Stock, or securities convertible into Common Stock, with a purchase,
exercise or conversion price (the "Share Antidilution Price") of less than the
Share Issue Price (which shall initially be $4.00, as adjusted for stock splits,
stock dividends and the like), with certain exceptions set forth below, the
Company shall promptly issue to each investor in the Offering additional shares
of Common Stock.

     (ii) The number of additional shares of Common Stock issuable to each
investor shall be equal to the difference between "A" and "B", where :

         (Number of Shares Purchased in this Offering* X Share Issue Price*)
     A =  -----------------------------------------------------------------
                                Share Antidilution Price

     and

     B = The number of Shares acquired by such investor in this Offering plus
the number of additional shares of Common Stock previously issued to such
investor pursuant to this Clause (b)*

         *(giving effect to stock splits, stock dividends, and the like)

The number of additional shares issued to each investor will be rounded down to
the nearest whole share, and no fractional shares will be issued.

     (iii) Notwithstanding the foregoing, the following issuances by the Company
shall not result in any issuance of additional shares to investors in the
Offering: (A) shares of Common Stock issued upon conversion of Preferred Stock,
(B) up to 5,000,000 shares of Common Stock and/or options, and the Common Stock
issued pursuant to such options, (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like, and net of any repurchases
of such shares or cancellations or exemptions of such options, warrants or other
rights) to employees, officers or directors of, or consultants or advisors to
the Corporation or any subsidiary pursuant to stock purchase or stock option
plans or other arrangements that are


                                       26

<PAGE>

approved by the Board ("Employee Options"), (C) shares of capital stock issuable
upon exercise or conversion of options (other than Employee Options) or warrants
or other securities or rights outstanding as of the date of the Memorandum and
(D) shares of Common Stock issued to third parties in connection with bank loan
or license arrangements or other strategic transactions approved by the Board of
Directors.

     (iv) Within 15 days following any transaction by the Company which would
result in the investors in the Offering being entitled to additional shares of
Common Stock hereunder, the Company shall provide written notice of such
transaction to each investor and the Placement Agent of the terms of such
transaction and shall, within 30 days of consummation of such transaction,
deliver share certificates to the investors (or the Placement Agent on their
behalf) representing any additional shares. Any such additional shares shall be
included in the term "Registrable Securities" in Section G clause (a) above.

     (C) PUT OPTION ON MERGER OR CONSOLIDATION.

     (i) In the event of a merger or consolidation where the Company is not the
surviving entity or sale of substantially all of the assets of the Company
during the term commencing on the Initial Closing of the Offering and ending on
the day prior to the effective date of an initial public offering (a
"liquidation event"), the Company hereby agrees that, unless waived by the
Placement Agent on behalf of all investors in the Offering, investors in this
Offering shall have the option to put their shares back to the Company
immediately prior to and conditioned upon consummation of such liquidation event
in exchange for a payment in cash equal to 150% of their original subscription
amount (the "Put Price"); provided, however, in the event that: (A) the third
party to the liquidation event is a reporting company under the Securities and
Exchange Act of 1934; (B) its shares of publicly traded securities are being
used as consideration in the Offering; (C) such securities are traded on either
the New York Stock Exchange, the American Stock Exchange or the Nasdaq Stock
Market and (D) the securities have a closing sales price in excess of $5.00 per
share for the 30 trading days prior to announcement of such transaction and a
daily average volume equal to or in excess of 50,000 shares per day, such
payment may be made in the form of such securities provided that the securities
are immediately available for resale pursuant to Rule 145 or a resale
registration statement.

     (ii) At least 15 days prior to any transaction by the Company which would
result in the investors in the Offering being entitled to exercise their put
rights hereunder, the Company shall provide written notice of such transaction
to each investor and the Placement Agent of the terms of such transaction.
Investors shall have 10 days to notify the Company in writing of their desire to
exercise or not exercise their put rights hereunder, or the Placement Agent may
so notify the Company on behalf of all investors. To the extent that an investor
or the Placement Agent on behalf of such investor, as the case may be, does not
provide the notice as set forth in the immediately preceding sentence, such
investor will be deemed to have irrevocably agreed not to exercise their put
right hereunder.

     (iii) The closing for the purchase of the Shares for which put rights have
been timely exercised hereunder (the "Put Securities") will occur as soon as
practicable following the consummation of the transaction giving rise to the put
rights hereunder by the Company's


                                       27

<PAGE>

prompt payment of the Put Price following receipt of original certificates for
the Put Securities, duly endorsed or accompanied by an appropriate stock power.
If the Company does not have sufficient funds legally available to pay the Put
Price for the Put Securities under the Delaware General Corporation Law or
otherwise, then the Company will purchase the maximum number of Put Securities
for which the Company has funds legally available, pro rata based upon the
number of Put Securities tendered hereunder. The remaining shares which cannot
be purchased because of the lack of funds available to the Company shall be
exchanged for new shares of the merged entity at the Put Price.

     (D)  ISSUANCE OF ADDITIONAL SHARES FOR FAILURE TO TIMELY BECOME REPORTING
          COMPANY.

     (i) Unless waived by the Placement Agent on behalf of all investors in the
Offering, in the event that the Company fails to become a reporting company
under the Securities Exchange Act of 1934 within a date which is within 24
months following the date of the final Closing of the Offering, then the
undersigned subscriber shall be entitled to additional shares of Common Stock of
the Company determined by dividing (A) 10% of his initial subscription by (B)
the lower of (x) the price per Share in the Offering or (y) the lowest price per
share received by the Company in connection with any sale (other than issuances
described in Section H clause (b)(iii) above) of its common stock (or in the
event of the issuance or sale of convertible securities, the conversion or
exercise price) within 6 months of such date. In addition, unless waived by the
Placement Agent on behalf of all investors in the Offering, in the event of the
Company's failure to become a reporting company continues after 24 months
following the date of the final Closing of the Offering, then, beginning on the
date 27 months following the date of the final Closing of the Offering, for each
90 day period (or part thereof) of such continued failure by the Company, the
undersigned subscriber shall be entitled to additional shares of Common Stock of
the Company determined by dividing (A) 5% of his initial subscription by (B) the
lower of (x) the price per Share in the Offering or (y) the lowest price per
share received by the Company in connection with any sale (other than issuances
described in Section H clause (b)(iii) above) of its common stock (or in the
event of the issuance or sale of convertible securities, the conversion or
exercise price) within 6 months of any such date.

     (ii) Within 15 days following the date on which investors in the Offering
become entitled to additional shares of Common Stock hereunder, the Company
shall provide written notice of such entitlement to each investor and the
Placement Agent and shall, within 30 days of consummation of such transaction,
deliver share certificates to the investors (or the Placement Agent on their
behalf) representing any additional shares. Any such additional shares shall be
included in the term "Registrable Securities" in Section H clause (a) above.

     (E)  COMPANY RIGHT OF FIRST REFUSAL.

     (i) In the event any Registrable Securities, or any interest therein, are
to be transferred, voluntarily or involuntarily (including, without limitation,
any sale, encumbrance, foreclosure or transfer in lieu thereof, or by operation
of law, any division of marital property on account of divorce or legal
separation being deemed a "transfer" for purposes hereof), the Company (or its
nominees) shall have a right of first refusal as follows:


                                       28

<PAGE>

          (A) the holder of such Registrable Securities shall give the Company
advance written notice detailing all the terms of the proposed transfer. The
Company (or its nominees) shall have the right (but not the obligation),
exercisable upon delivery to the transferring stockholder of written notice of
acceptance within 10 days following receipt of the notice of proposed transfer
described in the preceding sentence, to repurchase all or any of such
Registrable Securities on the terms and conditions set forth in such notice.

          (B) The "Payment Date" for purposes of this paragraph shall be on or
before the 10th day following delivery of the Company's notice of exercise.
Holder will surrender all stock certificates to the Company promptly upon
request on or before the Payment Date.

          (C) Failure by the Company (or its nominees) (without default by the
transferring stockholder) to close such purchase within the above 10-day period
shall give the transferring stockholder the right to transfer such shares or
interest therein on the terms and to the person described in the notice during
the 45 days following expiration of the original 10-day period; provided that
the shares or interest therein to be transferred shall for all purposes remain
subject to the Company's right of first refusal hereunder. If the transferring
stockholder fails to close the proposed transfer on those terms within such
45-day period, the proposed transfer shall again be subject to the terms of this
paragraph.

          (D) Notwithstanding the foregoing, nothing herein shall be construed
to impede or nullify any transfer of such shares made to any trusts in which a
holder of Registrable Securities or a member of such holder's immediate family
are trustors or the beneficiaries thereof, or to a partnership, limited
liability company or other entity of which such holder and member(s) of such
holder's immediate family are the sole equity owners, and in each of the
foregoing cases where such trust or entity is controlled by such holder,
directly or indirectly, whether or not for adequate consideration. Such
transfers may be made without providing the Company notice or a right of first
refusal. The transferee of such shares shall at all times be bound by the
restrictions provided in this paragraph with regard to future transactions and
shall execute an appropriate instrument to this effect. Certificates evidencing
Shares issued in the Offering will be legended to reflect the foregoing
restrictions (see above). This right of first refusal shall expire on the date
that the Company becomes a reporting company under the Securities Exchange Act
of 1934.

     (F)  AUTHORIZATION OF PLACEMENT AGENT AS AGENT FOR PURPOSES OF SECTION H
          CLAUSES (B), (C) AND (D) AND OTHER WAIVERS AND AMENDMENTS.
