NUMBER                     (SEE REVERSE LEGEND)                        WARRANTS
__________-     (THIS WARRANT WILL BE VOID IF NOT EXERCISED PRIOR
                TO 5:00 P.M. NEW YORK CITY TIME, __________, 2007

                       GREAT WALL ACQUISITION CORPORATION

                                     WARRANT

THIS CERTIFIES THAT, for value received

is the registered holder of a Warrant or Warrants expiring ________, 2008 (the
"Warrant") to purchase one fully paid and non-assessable share of Common Stock,
par value $.0001 per share ("Shares"), of Great Wall Acquisition Corporation, a
Delaware corporation (the "Company") for each Warrant evidenced by this Warrant
Certificate. The Warrant entitles the holder thereof to purchase from the
Company, commencing on the later of (i) the consummation by the Company of a
merger, capital stock exchange, asset acquisition or other similar business
combination or (ii) __________, 2004, such number of Shares of the Company at
the price of $5.00 per share, upon surrender of this Warrant Certificate and
payment of the Warrant Price at the office or agency of the Warrant Agent,
Continental Stock Transfer & Trust Company (such payment to be made by check
made payable to the Warrant Agent), but only subject to the conditions set forth
herein and in the Warrant Agreement between the Company and Continental Stock
Transfer & Trust Company. The Warrant Agreement provides that upon the
occurrence of certain events the Warrant Price and the number of Warrant Shares
purchasable hereunder, set forth on the face hereof, may, subject to certain
conditions, be adjusted. The term Warrant Price as used in this Warrant
Certificate refers to the price per Share at which Shares may be purchased at
the time the Warrant is exercised.

     No fraction of a Share will be issued upon any exercise of a Warrant. If
the holder of a Warrant would be entitled to receive a fraction of a Share upon
any exercise of a Warrant, the Company shall, upon such exercise, round up to
the nearest whole number the number of Shares to be issued to such holder.

     Upon any exercise of the Warrant for less than the total number of full
Shares provided for herein, there shall be issued to the registered holder
hereof or his assignee a new Warrant Certificate covering the number of Shares
for which the Warrant has not been exercised.

     Warrant Certificates, when surrendered at the office or agency of the
Warrant Agent by the registered holder hereof in person or by attorney duly
authorized in writing, may be exchanged in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

     Upon due presentment for registration of transfer of the Warrant
Certificate at the office or agency of the Warrant Agent, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee in
exchange for this Warrant Certificate, subject to the limitations provided in
the Warrant Agreement, without charge except for any applicable tax or other
governmental charge.

     The Company and the Warrant Agent may deem and treat the registered holder
as the absolute owner of this Warrant Certificate (notwithstanding any notation
of ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, of any distribution to the registered holder, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

     This Warrant does not entitle the registered holder to any of the rights of
a Stockholder of the Company until exercised.

     The Company reserves the right to call the Warrant, at any time prior to
its exercise, with a notice of call in writing to the Warrantholders of Record,
giving 30 days' notice of such call at any time after the Warrant becomes
exercisable if the last sale price of the Shares has been at least $8.50 per
share on each of 20 trading days within any 30 trading day period ending on the
third business day prior to the date on which notice of such call is given. The
call price of the Warrants is to be $.01 per Warrant. Any Warrant either not
exercised, or tendered back to the Company by the end of the date specified in
the notice of call, shall be canceled on the books of the Company and have no
further value except for the $.01 call price.

         ---------------

                  THIS CERTIFIES THAT, in consideration of $_____ per option
duly paid by or on behalf of ____________________ ("Holder"), as registered
owner of this Purchase Option, to Great Wall Acquisition Corporation
("Company"), Holder is entitled, at any time or from time to time upon the later

Company, each Unit consisting of one share of common stock of the Company, par
value $.0001 per share ("Common Stock"), and two warrants ("Warrant(s)")
expiring five years from the effective date ("Effective Date") of the
registration statement ("Registration Statement") pursuant to which Units are
offered for sale to the public ("Offering"). Each Warrant is the same as the
warrants included in the Units being registered for sale to the public by way of
the Registration Statement ("Public Warrants"). If the Expiration Date is a day
on which banking institutions are authorized by law to close, then this Purchase
Option may be exercised on the next succeeding day which is not such a day in
accordance with the terms herein. During the period ending on the Expiration
Date, the Company agrees

                                       1

not to take any action that would terminate the Purchase Option. This Purchase
Option is initially exercisable at $6.60 per Unit so purchased; provided,
however, that upon the occurrence of any of the events specified in Section 6
hereof, the rights granted by this Purchase Option, including the exercise price
per Unit and the number of Units (and shares of Common Stock and Warrants) to be
received upon such exercise, shall be adjusted as therein specified. The term
"Exercise Price" shall mean the initial exercise price or the adjusted exercise
price, depending on the context.

2.       Exercise.
         --------

         2.1 Exercise Form. In order to exercise this Purchase Option, the
exercise form attached hereto must be duly executed and completed and delivered
to the Company, together with this Purchase Option and payment of the Exercise
Price for the Units being purchased payable in cash or by certified check or
official bank check. If the subscription rights represented hereby shall not be
exercised at or before 5:00 p.m., Eastern time, on the Expiration Date this
Purchase Option shall become and be void without further force or effect, and
all rights represented hereby shall cease and expire.

         2.2 Legend. Each certificate for the securities purchased under this
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
shares of Common Stock and Warrants 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, the term "Current Market Value" per Unit at any
date means 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) the Current Market Price
of the Common Stock multiplied by the number of shares of Common Stock
underlying the Warrants and the Common Stock issuable upon exercise of one Unit.
The "Current Market Price" of a share of Common Stock shall mean (i) if the
Common Stock is listed on a national securities exchange or quoted on the Nasdaq
National Market, Nasdaq SmallCap Market or NASD OTC Bulletin Board (or successor
such as the Bulletin Board Exchange), the last sale price of the

                                       2

Common Stock in the principal trading market for the Common Stock as reported by
the exchange, Nasdaq or the NASD, as the case may be; (ii) if the Common Stock
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 such
as the Bulletin Board Exchange), but is traded in the residual over-the-counter
market, the closing bid price for the Common Stock 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.

                  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 a 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.

3.       Transfer.
         --------

         3.1 General Restrictions. The registered Holder of this Purchase
Option, by its acceptance hereof, agrees that it will not sell, transfer,
assign, pledge or hypothecate this Purchase Option for a period of one year
following the Effective Date to anyone other than (i) Broadband or an
underwriter or a selected dealer in connection with the Offering, or (ii) a bona
fide officer or partner of Broadband or of any such underwriter or selected
dealer. On and after 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 on the books of the Company and shall execute and deliver a new 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 (the Company hereby agreeing that the
opinion of Littman Krooks LLP shall be deemed satisfactory evidence of the
availability of an exemption), 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 and compliance with applicable state
securities law has been established.

                                       3

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 exercise or assignment form and funds sufficient to pay any Exercise
Price and/or transfer tax if exercised pursuant to Section 2.1 hereto, 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 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 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 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 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
Registerable Securities within ten days from the date of the receipt of any such
Initial Demand Notice.

                  5.1.2 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 twelve consecutive months from
the effective date of such registration statement or post-effective amendment.

                                       4

         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 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 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.

                  5.2.2 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. 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 business 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 twelve 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), 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

                                       5

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. 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 Exclusivity. The Company shall not permit the inclusion
of any securities other than the Registrable Securities to be included in any
registration statement filed pursuant to Section 5.1 hereof without the prior
written consent of the Majority Holders of the Registrable Securities.

                  5.4.4 Documents Delivered to Holders. The Company shall
furnish Broadband, 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 Broadband, as representative of the Holders
participating in the offering, the correspondence 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
Broadband, 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 Broadband, as representative of the Holders, shall
reasonably request. The Company shall not be required to disclose any
confidential information or other records to Broadband, 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.

                  5.4.5 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.

                  5.4.6 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).

                  5.4.7 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 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 day 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, 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.

                                       8

                  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 outstanding, the Company shall use its best efforts to cause
all (i) 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 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 or to receive notice
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.

         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.

         8.4 Transmittal of Notices. All notices, requests, consents and other
communications under this Purchase Option shall be in writing and shall be
deemed to have been duly made when hand delivered, or mailed by express mail or
private courier service: (i) If to the registered Holder of the Purchase Option,
to the address of such Holder as shown on the books of the Company, or (ii) if
to the Company, to following address or to such other address as the Company may
designate by notice to the Holders:

9.       Miscellaneous.
         -------------

         9.1 Amendments. The Company and Broadband may from time to time
supplement or amend this Purchase Option without the approval of any of the
Holders in order to cure any ambiguity, to correct or supplement any provision
contained herein that may be defective or inconsistent with any other provisions
herein, or to make any other provisions in regard to matters or questions
arising hereunder that the Company and Broadband may deem necessary or desirable
and that the Company and Broadband deem shall not adversely affect the interest
of the Holders. All other modifications or amendments shall require the written
consent of and be signed by the party against whom enforcement of the
modification or amendment is sought.

         9.2 Headings. The headings contained herein are for the sole purpose of
convenience of reference, and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Purchase Option.

10. Entire Agreement. This Purchase Option (together with the other agreements
and documents being delivered pursuant to or in connection with this Purchase
Option) constitutes the entire agreement of the parties hereto with respect to
the subject matter hereof, and supersedes all prior agreements and
understandings of the parties, oral and written, with respect to the subject
matter hereof.

         10.1 Binding Effect. This Purchase Option shall inure solely to the
benefit of and shall be binding upon, the Holder and the Company and their
permitted assignees, respective successors, legal representative and assigns,
and no other person shall have or be construed to have any legal or equitable

Option or any provisions herein contained.

         10.2 Governing Law; Submission to Jurisdiction. This Purchase Option
shall be governed by and construed and enforced in accordance with the laws of
the State of New York, without giving effect to conflict of laws. The Company
hereby agrees that any action, proceeding or claim against it arising out of, or
relating in any way to this Purchase Option shall be brought and enforced in the
courts of the State of New York or of the United States of America for the
Southern District of New York, and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive. The Company hereby waives any objection
to such exclusive jurisdiction and that such courts represent an inconvenient
forum. Any process or summons to be served upon the Company may be served by
transmitting a copy thereof by registered or certified mail, return receipt
requested, postage prepaid, addressed to it at the address set forth in Section
8 hereof. Such mailing shall be deemed personal service and shall be legal and

Holder agree that the prevailing party(ies) in any such action shall be entitled
to recover from the other party(ies) all of its reasonable attorneys' fees and

with the preparation therefor.

         10.3 Waiver, Etc. The failure of the Company or the Holder to at any
time enforce any of the provisions of this Purchase Option shall not be deemed

Company or any Holder to thereafter enforce each and every provision of this
Purchase Option. No waiver of any breach, non-compliance or non-fulfillment of
any of the provisions of this Purchase Option shall be effective unless set

subsequent breach, non-compliance or non-fulfillment.

acceptance of this Purchase Option, Holder agrees that, at any time prior to the
complete exercise of this Purchase Option by Holder, if the Company and
Broadband enter into an agreement ("Exchange Agreement") pursuant to which they
agree that all outstanding Purchase Options will be exchanged for securities or
cash or a combination of both, then Holder shall agree to such exchange and
become a party to the Exchange Agreement.
