Purchase Option shall bear a legend as follows unless such securities have been
registered under the Securities Act of 1933, as amended ("Act"):

            "The securities represented by this certificate have not been
            registered under the Securities Act of 1933, as amended ("Act") or
            applicable state law. The securities may not be offered for sale,
            sold or otherwise transferred except pursuant to an effective
            registration statement under the Act, or pursuant to an exemption
            from registration under the Act and applicable state law."

      2.3   Cashless Exercise.

            2.3.1 Determination of Amount. In lieu of the payment of the
Exercise Price multiplied by the number of Units for which this Purchase Option
is exercisable (and in lieu of being entitled to receive Common Stock and
Warrants) in the manner required by Section 2.1, the Holder shall have the right
(but not the obligation) to convert any exercisable but unexercised portion of
this Purchase Option into Units ("Conversion Right") as follows: upon exercise
of the Conversion Right, the Company shall deliver to the Holder (without
payment by the Holder of any of the Exercise Price in cash) that number of Units
(or that number of shares of Common Stock and Warrants (or that number of shares
of comprising that number of Units) equal to the quotient obtained by dividing
(x) the "Value" (as defined below) of the portion of the Purchase Option being
converted by (y) the Current Market Value (as defined below). The "Value" of the
portion of the Purchase Option being converted shall equal the remainder derived
from subtracting (a) (i) the Exercise Price multiplied by (ii) the number of
Units underlying the portion of this Purchase Option being converted from (b)
the Current Market Value of a Unit multiplied by the number of Units underlying
the portion of the Purchase Option being converted. As used herein,

                                       2


<PAGE>

the term "Current Market Value" per Unit at any date means: (A) in the event
that neither the Units nor Public Warrants are still trading, the remainder
derived from subtracting (x) the exercise price of the Warrants multiplied by
the number of shares of Common Stock issuable upon exercise of the Warrants
underlying one Unit from (y) (i) the Current Market Price of the Common Stock
multiplied by (ii) the number of shares of Common Stock underlying one Unit,
which shall include the shares of Common Stock underlying the Warrants included
in such Unit; (B) in the event that the Units, Common Stock and Public Warrants
are still trading, (i) if the Units are listed on a national securities exchange
or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or NASD OTC
Bulletin Board (or successor exchange), the last sale price of the Units in the
principal trading market for the Units as reported by the exchange, Nasdaq or
the NASD, as the case may be, on the last trading day preceding the date in
question; or (ii) if the Units are not listed on a national securities exchange
or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC
Bulletin Board (or successor exchange), but is traded in the residual
over-the-counter market, the closing bid price for Units on the last trading day
preceding the date in question for which such quotations are reported by the
Pink Sheets, LLC or similar publisher of such quotations; and (C) in the event
that the Units are not still trading but the Common Stock and Public Warrants
underlying the Units are still trading, the Current Market Price of the Common
Stock plus the product of (x) the Current Market Price of the Public Warrants
and (y) the number of shares of Common Stock underlying the Warrants included in
one Unit. The "Current Market Price" shall mean (i) if the Common Stock (or
Public Warrants, as the case may be) is listed on a national securities exchange
or quoted on the Nasdaq National Market, Nasdaq SmallCap Market or NASD OTC
Bulletin Board (or successor exchange), the last sale price of the Common Stock
(or Public Warrants) in the principal trading market for the Common Stock as
reported by the exchange, Nasdaq or the NASD, as the case may be, on the last
trading day preceding the date in question; (ii) if the Common Stock (or Public
Warrants, as the case may be) is not listed on a national securities exchange or
quoted on the Nasdaq National Market, Nasdaq SmallCap Market or the NASD OTC
Bulletin Board (or successor exchange), but is traded in the residual
over-the-counter market, the closing bid price for the Common Stock (or Public
Warrants) on the last trading day preceding the date in question for which such
quotations are reported by the Pink Sheets, LLC or similar publisher of such
quotations; and (iii) if the fair market value of the Common Stock cannot be
determined pursuant to clause (i) or (ii) above, such price as the Board of
Directors of the Company shall determine, in good faith. In the event the Public
Warrants have expired and are no longer exercisable, no "Value" shall be
attributed to the Warrants underlying this Purchase Option. Additionally, in the
event this Purchase Option is exercised pursuant to this Section 2.3 and the
Public Warrants are still trading, the "Value" shall be reduced by the
difference between the Warrant Exercise Price and the exercise price of the
Public Warrants.

            2.3.2 Mechanics of Cashless Exercise. The Cashless Exercise Right
may be exercised by the Holder on any business day on or after the Commencement
Date and not later than the Expiration Date by delivering the Purchase Option
with the duly executed exercise form attached hereto with the cashless exercise
section completed to the Company, exercising the Cashless Exercise Right and
specifying the total number of Units the Holder will purchase pursuant to such
Cashless Exercise Right.

selected dealer in connection with the Offering, or (ii) a bona fide officer or

anniversary of the Effective Date, transfers to others may be made subject to
compliance with or exemptions from applicable securities laws. In order to make
any permitted assignment, the Holder must deliver to the Company the assignment
form attached hereto duly executed and completed, together with the Purchase
Option and payment of all transfer taxes, if any, payable in connection
therewith. The Company shall within five business days transfer this Purchase

Option or Purchase Options of like tenor to the appropriate assignee(s)
expressly evidencing the right to purchase the aggregate number of Units
purchasable hereunder or such portion of such number as shall be contemplated by
any such assignment.

      3.2 Restrictions Imposed by the Act. The securities evidenced by this
Purchase Option shall not be transferred unless and until (i) the Company has
received the opinion of counsel for the Holder that the securities may be
transferred pursuant to an exemption from registration under the Act and
applicable state securities laws, the availability of which is established to
the reasonable satisfaction of the Company, or (ii) a registration statement or
a post-effective amendment to the Registration Statement relating to such
securities has been filed by the Company and declared effective by the
Securities and Exchange Commission (the "Commission") and compliance with
applicable state securities law has been established.

4.    New Purchase Options to be Issued.

      4.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3
hereof, this Purchase Option may be exercised or assigned in whole or in part.
In the event of the exercise or assignment hereof in part only, upon surrender
of this Purchase Option for cancellation, together with the duly executed

and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Purchase Option of like tenor to this Purchase Option in
the name of the Holder evidencing the right of the Holder to purchase the number
of Units purchasable hereunder as to which this Purchase Option has not been
exercised or assigned.

      4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory
to it of the loss, theft, destruction or mutilation of this Purchase Option and
of reasonably satisfactory indemnification or the posting of a bond, the Company
shall execute and deliver a new Purchase Option of like tenor and date. Any such
new Purchase Option executed and delivered as a result of such loss, theft,
mutilation or destruction shall constitute a substitute contractual obligation
on the part of the Company.

5.    Registration Rights.

      5.1   Demand Registration.

            5.1.1 Grant of Right. The Company, upon written demand ("Initial
Demand Notice") of the Holder(s) of at least 51% of the Purchase Options and/or
the underlying Units and/or the underlying securities ("Majority Holders"),
agrees to register (the "Demand Registration") on one occasion, all or any
portion of the Purchase Options requested by the Majority Holders in the Initial
Demand Notice and all of the securities underlying such Purchase Options,
including the Units, Common Stock, the Warrants and the Common Stock underlying
the Warrants (collectively, the "Registrable Securities"). On such occasion, the
Company will file a registration statement or a post-effective

                                       4


<PAGE>

amendment to the Registration Statement covering the Registrable Securities
within sixty days after receipt of the Initial Demand Notice and use its best
efforts to have such registration statement or post-effective amendment declared
effective as soon as possible thereafter. The demand for registration may be
made at any time during a period of five years beginning on the Effective Date.
The Initial Demand Notice shall specify the number of shares of Registrable
Securities proposed to be sold and the intended method(s) of distribution
thereof. The Company covenants and agrees to give written notice of its receipt
of any Initial Demand Notice by any Holder(s) to all other registered Holders of
the Purchase Options and/or the Registrable Securities within ten days from the
date of the receipt of any such Initial Demand Notice. Each holder of
Registrable Securities who wishes to include all or a portion of such holder's
Registrable Securities in the Demand Registration (each such holder including
shares of Registrable Securities in such registration , a "Demanding Holder")
shall so notify the Company within fifteen (15) days after the receipt by the
holder of the notice from the Company. Upon any such request, the Demanding
Holders shall be entitled to have their Registrable Securities included in the
Demand Registration.

            5.1.2 Effective Registration. A registration will not count as a
Demand Registration until the registration statement filed with the Commission
with respect to such Demand Registration has been declared effective and the
Company has complied with all of its obligations under this Purchase Option with
respect thereto; provided, however, that if, after such registration statement
has been declared effective, the offering of Registrable Securities pursuant to
a Demand Registration is interfered with by any stop order or injunction of the
Commission or any other governmental agency or court, the registration statement
with respect to such Demand Registration will be deemed not to have been
declared effective, unless and until, (i) such stop order or injunction is
removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of
the Demanding Holders thereafter elect to continue the offering.

            5.1.3. Underwritten Offering. If the Majority Holders so elect and
such holders so advise the Company as part of the Initial Demand Notice, the
offering of such Registrable Securities pursuant to such Demand Registration
shall be in the form of an underwritten offering. In such event, the right of
any holder to include its Registrable Securities in such registration shall be
conditioned upon such holder's participation in such underwriting and the
inclusion of such holder's Registrable Securities in the underwriting to the
extent provided herein. All Demanding Holders proposing to distribute their
securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by the Majority Holders.

            5.1.4 Reduction of Offering. If the managing underwriter or
underwriters for a Demand Registration that is to be an underwritten offering
advises the Company and the Demanding Holders in writing that the dollar amount
or number of shares of Registrable Securities which the Demanding Holders desire
to sell, taken together with all other shares of Common Stock or other
securities which the Company desires to sell and the shares of Common Stock, if
any, as to which registration has been requested pursuant to written contractual
piggy-back registration rights held by other stockholders of the Company who
desire to sell, exceeds the maximum dollar amount or maximum number of shares
that can be sold in such offering without adversely affecting the proposed
offering price, the timing, the distribution method, or the probability of
success of such offering (such maximum dollar amount or maximum number of
shares, as applicable, the "Maximum Number of Shares"), then the Company shall
include in such registration: (i) first, the Registrable Securities as to which
Demand Registration has been requested by the Demanding Holders (pro rata in
accordance with the number of shares that each such person has requested be
included in such registration, regardless of the number of

                                       5


<PAGE>

shares held by each such person (such proportion is referred to herein as "Pro
Rata")) that can be sold without exceeding the Maximum Number of Shares; (ii)
second, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clause (i), the shares of Common Stock or other securities
that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (iii) third, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clauses (i) and (ii), the shares of
Common Stock or other securities registrable pursuant to the terms of the
Registration Rights Agreement between the Company and the initial investors in
the Company, dated as of ________, 2005 (the "Registration Rights Agreement" and
such registrable securities, the "Investor Securities") as to which "piggy-back"
registration has been requested by the holders thereof, Pro Rata, that can be
sold without exceeding the Maximum Number of Shares; and (iv) fourth, to the
extent that the Maximum Number of Shares have not been reached under the
foregoing clauses (i), (ii), and (iii), the shares of Common Stock or other
securities for the account of other persons that the Company is obligated to
register pursuant to written contractual arrangements with such persons and that
can be sold without exceeding the Maximum Number of Shares.

            5.1.5 Withdrawal. If a majority-in-interest of the Demanding Holders
disapprove of the terms of any underwriting or are not entitled to include all
of their Registrable Securities in any offering, such majority-in-interest of
the Demanding Holders may elect to withdraw from such offering by giving written
notice to the Company and the underwriter or underwriters of their request to
withdraw prior to the effectiveness of the registration statement filed with the
Commission with respect to such Demand Registration. If the majority-in-interest
of the Demanding Holders withdraws from a proposed offering relating to a Demand
Registration, then such registration shall not count as a Demand Registration
provided for in Section 5.1.

            5.1.6 Terms. The Company shall bear all fees and expenses attendant
to registering the Registrable Securities, including the expenses of any legal
counsel selected by the Holders to represent them in connection with the sale of
the Registrable Securities, but the Holders shall pay any and all underwriting
commissions. The Company agrees to use its reasonable best efforts to qualify or
register the Registrable Securities in such States as are reasonably requested
by the Majority Holder(s); provided, however, that in no event shall the Company
be required to register the Registrable Securities in a State in which such
registration would cause (i) the Company to be obligated to qualify to do
business in such State, or would subject the Company to taxation as a foreign
corporation doing business in such jurisdiction or (ii) the principal
stockholders of the Company to be obligated to escrow their shares of capital
stock of the Company. The Company shall cause any registration statement or
post-effective amendment filed pursuant to the demand rights granted under
Section 5.1.1 to remain effective for a period of nine consecutive months from
the effective date of such registration statement or post-effective amendment.

      5.2   "Piggy-Back" Registration.

            5.2.1 Grant of Right. In addition to the demand right of
registration, the Holders of the Purchase Options shall have the right for a
period of seven years commencing on the Effective Date, to include the
Registrable Securities as part of any other registration of securities filed by
the Company (other than in connection with a transaction contemplated by Rule
145(a) promulgated under the Act or pursuant to Form S-8); provided, however,
that if, in the written opinion of the Company's managing underwriter or
underwriters, if any, for such offering, the inclusion of the Registrable
Securities, when added to the securities being registered by the Company or the
selling stockholder(s), will exceed the

                                       6


<PAGE>

maximum amount of the Company's securities which can be marketed (i) at a price
reasonably related to their then current market value, and (ii) without
materially and adversely affecting the entire offering, then the Company will
still be required to include the Registrable Securities, but may require the
Holders to agree, in writing, to delay the sale of all or any portion of the
Registrable Securities for a period of 90 days from the effective date of the
offering, provided, further, that if the sale of any Registrable Securities is
so delayed, then the number of securities to be sold by all stockholders in such
public offering during such 90 day period shall be apportioned pro rata among
all such selling stockholders, including all holders of the Registrable
Securities, according to the total amount of securities of the Company owned by
said selling stockholders, including all holders of the Registrable Securities.
The Company shall give written notice of such proposed filing to the Holders of
the Purchase Options as soon as practicable, but in no event less than ten (10)
days before the anticipated filing date, which notice shall describe the amount
and type of securities to be included in such offering, the intended method(s)
of distribution, and the name of the proposed managing underwriter or
underwriters, if any, of the offering, and offer the Holders in such notice the
opportunity to register the sale of such number of shares of Registrable
Securities as such holders may request in writing within five (5) days following
receipt of such notice (a "Piggy-Back Registration"). All Holders proposing to
distribute their Registrable Securities through a Piggy-Back Registration that
involves an underwriter or underwriters shall enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for
such Piggy-Back Registration.

            5.2.2 Withdrawal. Any Holder of Registrable Securities may elect to
withdraw such Holder's request for inclusion of Registrable Securities in any
Piggy-Back Registration by giving written notice to the Company of such request
to withdraw prior to the effectiveness of the registration statement. The
Company (whether on its own determination or as the result of a withdrawal by
persons making a demand pursuant to written contractual obligations) may
withdraw a registration statement at any time prior to the effectiveness of the
registration statement. Notwithstanding any such withdrawal, the Company shall
pay all expenses incurred by the holders of Registrable Securities in connection
with such Piggy-Back Registration as provided in Section 5.2.3.

            5.2.3 Terms. The Company shall bear all fees and expenses attendant
to registering the Registrable Securities, including the expenses of any legal
counsel selected by the Holders to represent them in connection with the sale of
the Registrable Securities but the Holders shall pay any and all underwriting
commissions related to the Registrable Securities. In the event of such a
proposed registration, the Company shall furnish the then Holders of outstanding
Registrable Securities with not less than fifteen days written notice prior to
the proposed date of filing of such registration statement. Such notice to the
Holders shall continue to be given for each applicable registration statement
filed (during the period in which the Purchase Option is exercisable) by the
Company until such time as all of the Registrable Securities have been
registered and sold. The holders of the Registrable Securities shall exercise
the "piggy-back" rights provided for herein by giving written notice, within ten
days of the receipt of the Company's notice of its intention to file a
registration statement. The Company shall cause any registration statement filed
pursuant to the above "piggyback" rights to remain effective for at least nine
months from the date that the Holders of the Registrable Securities are first
given the opportunity to sell all of such securities.

      5.3 Damages. Should the registration or the effectiveness thereof required
by Sections 5.1 and 5.2 hereof be delayed by the Company or the Company
otherwise fails to comply with such provisions, the Company shall, in addition
to any other equitable or other relief available to the Holder(s), be liable for
any and all incidental, special and consequential damages sustained by the
Holder(s),

                                       7
<PAGE>

including, but not limited to, the loss of any profits that might have been
received by the holder upon the sale of shares of Common Stock or Warrants (and
shares of Common Stock underlying the Warrants) underlying this Purchase Option.

      5.4   General Terms.

            5.4.1 Indemnification. The Company shall indemnify the Holder(s) of
the Registrable Securities to be sold pursuant to any registration statement
hereunder and each person, if any, who controls such Holders 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 attorneys' fees and other expenses
reasonably incurred in investigating, preparing or defending against litigation,
commenced or threatened, or any claim whatsoever whether arising out of any
action between the underwriter and the Company or between the underwriter and
any third party or otherwise) to which any of them may become subject under the
Act, the Exchange Act or otherwise, arising from such registration statement but
only to the same extent and with the same effect as the provisions pursuant to
which the Company has agreed to indemnify the underwriters contained in Section
5 of the Underwriting Agreement between the Company, Rodman & Renshaw and the
other underwriters named therein dated the Effective Date. The Holder(s) of the
Registrable Securities to be sold pursuant to such registration statement, and
their successors and assigns, shall severally, and not jointly, indemnify the
Company, its officers and directors and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20(a) of the
Exchange Act, against all loss, claim, damage, expense or liability (including
all reasonable attorneys' fees and other 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
from information furnished by or on behalf of such Holders, or their successors
or assigns, in writing, for specific inclusion in such registration statement to
the same extent and with the same effect as the provisions contained in Section
5 of the Underwriting Agreement pursuant to which the underwriters have agreed
to indemnify the Company.

            5.4.2 Exercise of Purchase Options. Nothing contained in this
Purchase Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Warrants underlying such Purchase Options prior to or after
the initial filing of any registration statement or the effectiveness thereof.

            5.4.3 Documents Delivered to Holders. The Company shall furnish
Rodman & Renshaw, as representative of the Holders participating in any of the
foregoing offerings, a signed counterpart, addressed to the participating
Holders, of (i) an opinion of counsel to the Company, dated the effective date
of such registration statement (and, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under any
underwriting agreement related thereto), and (ii) a "cold comfort" letter dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting agreement) signed by the independent public accountants
who have issued a report on the Company's financial statements included in such
registration statement, in each case covering substantially the same matters
with respect to such registration statement (and the prospectus included
therein) and, in the case of such accountants' letter, with respect to events
subsequent to the date of such financial statements, as are customarily covered
in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities. The Company shall
also deliver promptly to Rodman & Renshaw, as representative of the Holders
participating in the offering, the correspondence

                                       8
<PAGE>

and memoranda described below and copies of all correspondence between the
Commission and the Company, its counsel or auditors and all memoranda relating
to discussions with the Commission or its staff with respect to the registration
statement and permit Rodman & Renshaw, as representative of the Holders, to do
such investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the National
Association of Securities Dealers, Inc. ("NASD"). Such investigation shall
include access to books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times and as often as Rodman & Renshaw,
as representative of the Holders, shall reasonably request. The Company shall
not be required to disclose any confidential information or other records to
Rodman & Renshaw, as representative of the Holders, or to any other person,
until and unless such persons shall have entered into reasonable confidentiality
agreements (in form and substance reasonably satisfactory to the Company), with
the Company with respect thereto.

            5.4.4 Underwriting Agreement. The Company shall enter into an
underwriting agreement with the managing underwriter(s), if any, selected by any
Holders whose Registrable Securities are being registered pursuant to this
Section 5, which managing underwriter shall be reasonably acceptable to the
Company. Such agreement shall be reasonably satisfactory in form and substance
to the Company, each Holder and such managing underwriters, and shall contain
such representations, warranties and covenants by the Company and such other
terms as are customarily contained in agreements of that type used by the
managing underwriter. The Holders shall be parties to any underwriting agreement
relating to an underwritten sale of their Registrable Securities and may, at
their option, require that any or all the representations, warranties and
covenants of the Company to or for the benefit of such underwriters shall also
be made to and for the benefit of such Holders. Such Holders shall not be
required to make any representations or warranties to or agreements with the
Company or the underwriters except as they may relate to such Holders and their
intended methods of distribution. Such Holders, however, shall agree to such
covenants and indemnification and contribution obligations for selling
stockholders as are customarily contained in agreements of that type used by the
managing underwriter. Further, such Holders shall execute appropriate custody
agreements and otherwise cooperate fully in the preparation of the registration
statement and other documents relating to any offering in which they include
securities pursuant to this Section 5. Each Holder shall also furnish to the
Company such information regarding itself, the Registrable Securities held by
it, and the intended method of disposition of such securities as shall be
reasonably required to effect the registration of the Registrable Securities.

            5.4.5 Rule 144 Sale. Notwithstanding anything contained in this
Section 5 to the contrary, the Company shall have no obligation pursuant to
Sections 5.1 or 5.2 for the registration of Registrable Securities held by any
Holder (i) where such Holder would then be entitled to sell under Rule 144
within any three-month period (or such other period prescribed under Rule 144 as
may be provided by amendment thereof) all of the Registrable Securities then
held by such Holder, and (ii) where the number of Registrable Securities held by
such Holder is within the volume limitations under paragraph (e) of Rule 144
(calculated as if such Holder were an affiliate within the meaning of Rule 144).

            5.4.6 Supplemental Prospectus. Each Holder agrees, that upon receipt
of any notice from the Company of the happening of any event as a result of
which the prospectus included in the 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, such Holder will
immediately discontinue disposition of

                                       9
<PAGE>

Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until such Holder's receipt of the copies of a
supplemental or amended prospectus, and, if so desired by the Company, such
Holder shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a certificate of such destruction) all copies, other
than permanent file copies then in such Holder's possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice.

6.    Adjustments.

      6.1 Adjustments to Exercise Price and Number of Securities. The Exercise
Price and the number of Units underlying the Purchase Option shall be subject to
adjustment from time to time as hereinafter set forth:

            6.1.1 Stock Dividends - Split-Ups. If after the date hereof, and
subject to the provisions of Section 6.4 below, the number of outstanding shares
of Common Stock is increased by a stock dividend payable in shares of Common
Stock or by a split-up of shares of Common Stock or other similar event, then,
on the effective date thereof, the number of shares of Common Stock underlying
each of the Units purchasable hereunder shall be increased in proportion to such
increase in outstanding shares. In such case, the number of shares of Common
Stock, and the exercise price applicable thereto, underlying the Warrants
underlying each of the Units purchasable hereunder shall be adjusted in
accordance with the terms of the Warrants. For example, if the Company declares
a two-for-one stock dividend and at the time of such dividend this Purchase
Option is for the purchase of one Unit at $6.60 per whole Unit (each Warrant
underlying the Units is exercisable for $5.00 per share), upon effectiveness of
the dividend, this Purchase Option will be adjusted to allow for the purchase of
one Unit at $6.60 per Unit, each Unit entitling the holder to receive two shares
of Common Stock and four Warrants (each Warrant exercisable for $2.50 per
share).

            6.1.2 Aggregation of Shares. If after the date hereof, and subject
to the provisions of Section 6.4, the number of outstanding shares of Common
Stock is decreased by a consolidation, combination or reclassification of shares
of Common Stock or other similar event, then, on the effective date thereof, the
number of shares of Common Stock underlying each of the Units purchasable
hereunder shall be decreased in proportion to such decrease in outstanding
shares. In such case, the number of shares of Common Stock, and the exercise
price applicable thereto, underlying the Warrants underlying each of the Units
purchasable hereunder shall be adjusted in accordance with the terms of the
Warrants.

            6.1.3 Replacement of Securities upon Reorganization, etc. In case of
any reclassification or reorganization of the outstanding shares of Common Stock
other than a change covered by Section 6.1.1 or 6.1.2 hereof or that solely
affects the par value of such shares of Common Stock, or in the case of any
merger or consolidation of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or reorganization
of the outstanding shares of Common Stock), or in the case of any sale or
conveyance to another corporation or entity of the property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved, the Holder of this Purchase Option shall have the right thereafter
(until the expiration of the right of exercise of this Purchase Option) to
receive upon the exercise hereof, for the same aggregate Exercise Price payable
hereunder immediately prior to such event, the kind and amount of shares of
stock or other securities or property (including cash) receivable upon such
reclassification, reorganization, merger or consolidation,

                                       10
<PAGE>

or upon a dissolution following any such sale or transfer, by a Holder of the
number of shares of Common Stock of the Company obtainable upon exercise of this
Purchase Option and the underlying Warrants immediately prior to such event; and
if any reclassification also results in a change in shares of Common Stock
covered by Section 6.1.1 or 6.1.2, then such adjustment shall be made pursuant
to Sections 6.1.1, 6.1.2 and this Section 6.1.3. The provisions of this Section
6.1.3 shall similarly apply to successive reclassifications, reorganizations,
mergers or consolidations, sales or other transfers.

            6.1.4 Changes in Form of Purchase Option. This form of Purchase
Option need not be changed because of any change pursuant to this Section, and
Purchase Options issued after such change may state the same Exercise Price and
the same number of Units as are stated in the Purchase Options initially issued
pursuant to this Agreement. The acceptance by any Holder of the issuance of new
Purchase Options reflecting a required or permissive change shall not be deemed
to waive any rights to an adjustment occurring after the Commencement Date or
the computation thereof.

      6.2   [Intentionally Omitted]

      6.3 Substitute Purchase Option. In case of any consolidation of the
Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding Common Stock), the
corporation formed by such consolidation or merger shall execute and deliver to
the Holder a supplemental Purchase Option providing that the holder of each
Purchase Option then outstanding or to be outstanding shall have the right
thereafter (until the stated expiration of such Purchase Option) to receive,
upon exercise of such Purchase Option, the kind and amount of shares of stock
and other securities and property receivable upon such consolidation or merger,
by a holder of the number of shares of Common Stock of the Company for which
such Purchase Option might have been exercised immediately prior to such
consolidation, merger, sale or transfer. Such supplemental Purchase Option shall
provide for adjustments which shall be identical to the adjustments provided in
Section 6. The above provision of this Section shall similarly apply to
successive consolidations or mergers.

      6.4 Elimination of Fractional Interests. The Company shall not be required
to issue certificates representing fractions of shares of Common Stock or
Warrants upon the exercise of the Purchase Option, nor shall it be required to
issue scrip or pay cash in lieu of any fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Warrants, shares of Common Stock or
other securities, properties or rights.

7.    Reservation and Listing. The Company shall at all times reserve and
keep available out of its authorized shares of Common Stock, solely for the
purpose of issuance upon exercise of the Purchase Options or the Warrants
underlying the Purchase Option, such number of shares of Common Stock or other
securities, properties or rights as shall be issuable upon the exercise thereof.
The Company covenants and agrees that, upon exercise of the Purchase Options and
payment of the Exercise Price therefor, all shares of Common Stock and other
securities issuable upon such exercise shall be duly and validly issued, fully
paid and non-assessable and not subject to preemptive rights of any stockholder.
The Company further covenants and agrees that upon exercise of the Warrants
underlying the Purchase Options and payment of the respective Warrant exercise
price therefor, all shares of Common Stock and other securities issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable
and not subject to preemptive rights of any stockholder. As long as the Purchase
Options shall be

                                       11
<PAGE>

outstanding, the Company shall use its best efforts to cause all (i) Units and
shares of Common Stock issuable upon exercise of the Purchase Options, (ii)
Warrants issuable upon exercise of the Purchase Options and (iii) shares of
Common Stock issuable upon exercise of the Warrants included in the Units
issuable upon exercise of the Purchase Option to be listed (subject to official
notice of issuance) on all securities exchanges (or, if applicable on the Nasdaq
National Market, SmallCap Market, OTC Bulletin Board or any successor trading
market) on which the Units, the Common Stock or the Public Warrants issued to
the public in connection herewith may then be listed and/or quoted.

8.    Certain Notice Requirements.

      8.1 Holder's Right to Receive Notice. Nothing herein shall be construed as
conferring upon the Holders the right to vote or consent as a stockholder for
the election of directors or any other matter, or as having any rights
whatsoever as a stockholder of the Company. If, however, at any time prior to
the expiration of the Purchase Options and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the
Company shall give written notice of such event at least fifteen days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify such record date or the date of the closing of the transfer books, as
the case may be. Notwithstanding the foregoing, the Company shall deliver to
each Holder a copy of each notice given to the other stockholders of the Company
at the same time and in the same manner that such notice is given to the
stockholders.

      8.2 Events Requiring Notice. The Company shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution payable
otherwise than in cash, or a cash dividend or distribution payable otherwise
than out of retained earnings, as indicated by the accounting treatment of such
dividend or distribution on the books of the Company, or (ii) the Company shall
offer to all the holders of its Common Stock any additional shares of capital
stock of the Company or securities convertible into or exchangeable for shares
of capital stock of the Company, or any option, right or warrant to subscribe
therefor, or (iii) a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

      8.3 Notice of Change in Exercise Price. The Company shall, promptly after
an event requiring a change in the Exercise Price pursuant to Section 6 hereof,
send notice to the Holders of such event and change ("Price Notice"). The Price
Notice shall describe the event causing the change and the method of calculating
same and shall be certified as being true and accurate by the Company's
President and Chief Financial Officer.

9.    Miscellaneous.

      9.1 Amendments. The Company and Rodman & Renshaw may from time to time

Holders in order to cure any ambiguity, to correct or supplement any provision

arising hereunder that the Company and Rodman & Renshaw may deem necessary or
