                                 CLASS Z WARRANT

THIS CERTIFIES THAT, for value received

is the registered holder of a Warrant or Warrants expiring ________, 2012 (the
"Warrant") to purchase one fully paid and non-assessable share of Common Stock,
par value $.0001 per share ("Shares"), of Juniper Partners Acquisition Corp., 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 the consummation by the Company of a merger,
capital stock exchange, asset acquisition or other similar business combination
and __________ ___, 2006, such number of Shares of the Company at the price of
$5.00 per share (subject to adjustment), 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.
     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 holders of record of the
Warrant, 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 $8.75
per share (subject to adjustment) on any 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 $.05 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 $.05 call price.

1.       Purchase Option.

         THIS CERTIFIES THAT, in consideration of $100 duly paid by or on behalf
of HCFP/Brenner Securities LLC ("Holder"), as registered owner of this Purchase
Option, to Juniper Partners Acquisition Corp. ("Company"), Holder is entitled,
at any time or from time to time upon the later of the consummation of a
Business Combination or __________, 2006 ("Commencement Date"), and at or before
5:00 p.m., Eastern Time, ___________, 2010 ("Expiration Date"), but not

Twenty Five Thousand (25,000) Series A Units ("Series A Units") of the Company
and/or One Hundred Twenty Five Thousand (125,000) Series B Units ("Series B
Units" and together with the Series A Units, the "Units"). Each Series A Unit
consists of two shares of common stock of the Company, par value $.0001 per
share ("Common Stock"), five Class W Warrants ("Class W Warrants") and five
Class Z Warrants ("Class Z Warrants" and together with the Class W Warrants, the
"Warrants"). Each Series B Unit consists of two shares of Class B common stock
of the Company, par value $.0001 per share ("Class B Common Stock"), one Class W
Warrant and one Class Z Warrant. Each Warrant is the same as the warrants
("Public Warrants") included in the Units being offered for sale to the public
("Offering") by way of a registration statement ("Registration Statement")
except that the Warrants have an exercise price of $5.50 per share and the Class
Z Warrants included in this Purchase Option expire five years from the effective
date ("Effective Date") of the Registration Statement. 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 not to take any action that would terminate the
Purchase Option. This Purchase Option is initially exercisable at $____ per
Series A Unit and $____ per Series B 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 Common Stock in
the principal

                                       2

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
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.

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) Brenner or an underwriter
or a selected dealer in connection with the Offering, or (ii) a bona fide
officer or partner of Brenner or of any such underwriter or selected dealer. On
and after the first 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 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 Graubard Miller 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.

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, the Company shall cause to be delivered to the Holder
without charge a new Purchase Option of like tenor to

                                       3

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 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 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
Registrable 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 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

                                       4

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 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.

              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 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), 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, Brenner and the other
Underwriters named therein dated the Effective

                                       5

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
Brenner, 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 Brenner, 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 Brenner, 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 Brenner, as representative of the Holders,
shall reasonably request. The Company shall not be required to disclose any
confidential information or other records to Brenner, 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

                                       6

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
Section 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)
and the Holder is not an affiliate (as defined in Rule 144(a)) of the Company.

              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 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.

              5.4.7 Rule 144. The Company covenants that it shall file any
reports required to be filed by it under the Act and the Exchange Act and shall
take such further action as the holders of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holders to
sell Registrable Securities without registration under the Act within the
limitation of the exemptions provided by Rule 144, as such Rule may be amended
from time to time, or any similar Rule or regulation hereafter adopted by the
Securities and Exchange Commission.

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:

                                       7

              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.

              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.

              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]

                                       8

         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) Units and shares of Common Stock issuable upon exercise of the Purchase
Options, (iii) Warrants issuable upon exercise of the Purchase Options and (iv)
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

                                       9

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
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 in connection with 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 the following address or to such other address as the Company
may designate by notice to the Holders:

                                    Juniper Partners Acquisition Corp.
                                    56 West 45th Street, Suite 805
                                    New York, New York 10036
                                    Attn:   Stuart Rekant

9.       Miscellaneous.

         9.1 Amendments. The Company and Brenner 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 Brenner may deem necessary or desirable
and that the Company and Brenner 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

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
right, remedy or claim under or in respect of or by virtue of this Purchase
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
binding upon the Company in any action, proceeding or claim. The Company and the
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
expenses relating to such action or proceeding and/or incurred in connection
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
or construed to be a waiver of any such provision, nor to in any way affect the
validity of this Purchase Option or any provision hereof or the right of the
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
forth in a written instrument executed by the party or parties against whom or
which enforcement of such waiver is sought; and no waiver of any such breach,
non-compliance or non-fulfillment shall be construed or deemed to be a waiver of
any other or subsequent breach, non-compliance or non-fulfillment.

         10.4 Execution in Counterparts. This Purchase Option may be executed in
one or more counterparts, and by the different parties hereto in separate
counterparts, each of which shall be deemed to be an original, but all of which
taken together shall constitute one and the same agreement, and shall become
effective when one or more counterparts has been signed by each of the parties
hereto and delivered to each of the other parties hereto.

         10.5 Exchange Agreement. As a condition of the Holder's receipt and
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 Brenner
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.

                                       11

         10.6 Cancellation or Conversion of Class B Common Stock. At any time
after the consummation of a Business Combination thereby causing such Class B
Common Stock to be cancelled or converted pursuant to the terms of the Company's
Certificate of Incorporation, the rights of the Holder to exercise this Purchase
Option and obtain shares of Class B Common Stock underlying Series B Units shall
automatically be converted into the right to obtain the same number of shares of
Common Stock as the number of shares of Class B Common Stock as such holder
would have been entitled to obtain upon exercise of this Purchase Option.

         10.7 Underlying Warrants. At any time after exercise by the Holder of
this Purchase Option, the Holder may exchange his Warrants (with a $5.50
exercise price) for Public Warrants (with a $5.00 exercise price) upon payment
to the Company of the difference between the exercise price of his Warrant and
the exercise price of the Public Warrants.

                  IN WITNESS WHEREOF, the Company has caused this Purchase
Option to be signed by its duly authorized officer as of the ___ day of
