               WARRANTS FOR THE PURCHASE OF SHARES OF COMMON STOCK

         FOR VALUE RECEIVED, STREICHER MOBILE FUELING, INC., a Florida
corporation ("Streicher" or the "Company"), hereby certifies that EMERSON
BENNETT & ASSOCIATES (the "Holder") is entitled, subject to the provisions
contained herein, to purchase from the Company Thirty Thousand (30,000) duly
authorized, validly issued, fully paid and nonassessable shares of Common Stock
(as defined below), subject to adjustment as provided herein, at an exercise
price of $6.00 per share of Common Stock (the "Exercise Price").

         These Warrants have been issued in accordance with a Financial Advisory
Agreement dated March 11, 1999 and Amendment #1 to Financial Advisory Agreement,
dated August 12, 1999, which are attached herewith as Exhibit "A."

         The term "Common Stock" means the common stock, par value $.01, of the
Company as constituted on the date hereof. The number of shares of Common Stock
to be received upon the exercise of these Warrants may be adjusted from time to
time as hereinafter set forth. The shares of Common Stock deliverable upon such
exercise and any securities received in respect of any such shares, and as
adjusted from time to time, are hereinafter referred to as "Warrant Stock". The
term "Person" means an individual, a corporation, an association, a partnership,
a business, joint-stock company, a trust, any unincorporated organization, a
governmental or political subdivision thereof or a governmental agency.

         References herein to the "Company" are to (i) Streicher and any
successor thereto, (ii) any successor Person resulting from the merger or
consolidation of Streicher, or any successor thereto, with another Person or
(iii) any Person to which Streicher, or any successor thereto, has transferred
its property or assets as an entirety or substantially as an entirety.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of these Warrants, and (in the
case of loss, theft or destruction) of satisfactory indemnification, and upon
surrender and cancellation of these Warrants, if mutilated, the Company shall
execute and deliver new Warrants of like tenor and date.

         The Holder agrees with the Company that these Warrants are issued, and
all the rights hereunder shall be held, subject to all of the following
conditions, limitations and provisions:

         1. EXERCISE OF WARRANTS. 15,000 of the warrants shall vest and become
exercisable on December 11, 1999 and the remaining 15,000 warrants shall vest
and become exercisable on February 11,

<PAGE>

2000. Subject to the foregoing, any vested Warrants may be exercised, in whole
or in part, at any time, or from time to time during the period commencing on
the date hereof and expiring at 5:00 p.m., local time, on September 30, 2000 by
presentation and surrender of these Warrants to the Company at its principal
office (which on the date hereof is 2720 N.W. 55th Court, Ft. Lauderdale,
Florida 33309), with the Warrant Exercise Form attached hereto (or a reasonable
facsimile thereof) duly executed and accompanied by payment (either in cash or
by certified or official bank check payable to the order of the Company) of the
Exercise Price for the number of shares specified in such form (as such exercise
number shall be adjusted to reflect any adjustment in the total number of
Warrant Shares issuable to the Holder pursuant to the terms of this Warrant) and
the Holder shall thereupon be entitled to receive the number of duly authorized,
validly issued, fully paid and nonassessable shares of Common Stock determined
as provided herein. If these Warrants are exercised in part only, the Company
shall, upon surrender of these Warrants for cancellation, execute and deliver
new Warrants evidencing the rights of the Holder to purchase the balance of
Warrant Stock purchasable hereunder. Upon receipt by the Company of these
Warrants, together with the Exercise Price, in proper form for exercise, the
Holder shall be deemed to be the holder of record of the Warrant Stock issuable
upon such exercise, notwithstanding that the transfer books of the Company may
then be closed or that certificates representing such Warrant Stock shall not
then be actually delivered to the Holder. As soon as practicable after each
exercise from time to time of this Warrant, in whole or in part, the Company
will cause to be issued in the name of and delivered to the Holder, a
certificate or certificates for the number of duly authorized, validly issued,
fully paid and nonassessable shares of Common Stock to which the Holder is
entitled upon such exercise plus, in lieu of any fractional shares to which the
Holder would otherwise be entitled, cash as provided herein.

         2. RESERVATION OF SHARES. The Company will at all times reserve and
keep available for issuance and delivery upon exercise of these Warrants, all
shares of Warrant Stock from time to time issuable upon exercise of all Warrants
at the time outstanding. All such shares shall be duly authorized and, when
issued upon such exercise, shall be validly issued, fully paid and nonassessable
and free and clear of all preemptive or similar rights.

         3. FRACTIONAL SHARES. No fractional shares or scrip representing
fractional shares shall be issuable upon the exercise of these Warrants, but the
Company shall pay the Holder an amount equal to the fair market value of such
fractional share in lieu of each fraction of a share otherwise issuable upon any
exercise of these Warrants, as determined by the Board of Directors in its
reasonable discretion.

         4. EXCHANGE OF WARRANTS. These Warrants are exchangeable, without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company or at the office of its stock transfer agent, if any, for other
Warrants of different denominations, entitling the Holder hereof to purchase in
the aggregate the same number of shares of Warrant Stock purchasable hereunder.

         5. RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights as a shareholder of the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed herein.

         6.  ANTI-DILUTION PROVISIONS.

         6.1 ADJUSTMENT FOR RECAPITALIZATION. If the Company subdivides its
outstanding shares of Common Stock by recapitalization, reclassification or
split-up thereof, or if the Company declares a stock dividend or distribute
shares of Common Stock to its shareholders, the number of shares of Common Stock
subject to these Warrants immediately prior to such subdivision or dividend or
distribution shall be proportionately increased and the Exercise Price per share
shall be proportionately decreased, and if the

<PAGE>

Company combines the outstanding shares of Common Stock by recapitalization,
reclassification or combination thereof, the number of shares of Common Stock
subject to these Warrants immediately prior to such combination shall be
proportionately decreased and the Exercise Price per share shall be
proportionately increased. Any such adjustments pursuant to this Section 6.1
shall be effective at the close of business on the effective date of such
subdivision or combination or, if any adjustment is the result of a stock
dividend or distribution, then the effective date for such adjustment shall be
the record date therefor.

         6.2 ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION OR MERGER (a) If the
Company (or any other Person, the securities of which are at the time receivable
upon the exercise of these Warrants) reorganizes or reclassifies the Common
Stock after the date hereof or if the Company (or any such other Person)
consolidates with or merges into another Person and is not the continuing or
surviving Person of such consolidation or merger or in connection with such
consolidation or merger, the Common Stock is changed into or exchanged for stock
or other securities of any other Person or cash or any other property, or if the
Company (or any such other Person) conveys all or substantially all of its
assets to another Person, then, and in each such case, the Holder, upon the
exercise hereof, at any time after the consummation of such reorganization,
consolidation, merger or conveyance, shall be entitled to receive, in lieu of
the securities and property receivable upon the exercise of these Warrants prior
to such consummation, the same amount of securities or property to which the
Holder would have been entitled as a shareholder upon such consummation if the
Holder had exercised these Warrants immediately prior thereto (but had not
exercised any rights with respect to such securities or property in connection
with the reorganization, consolidation, merger or conveyance); in each such
case, the terms of these Warrants shall be applicable to the securities or
property receivable upon the exercise of these Warrants after such consummation.

         (b) If the Company consolidates with or merges into another Person, and
is not the surviving Person, or conveys all or substantially all of its assets
to another Person, then, and in each such case, the surviving Person or the
Person that receives substantially all of the Company's assets shall expressly
assume the obligations of the Company under these Warrants.

         6.3 NO IMPAIRMENT. The Company will not, by amendment of its charter or
through reorganization, consolidation, merger, dissolution, issue or sale of
securities, sale of assets or any other voluntary action, avoid or seek to avoid
the observance or performance of any of the terms of these Warrants, but will at
all times in good faith assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the Holder against dilution or other impairment. Without limiting
the generality of the foregoing, while these Warrants are outstanding, the
Company (a) will not permit the par value, if any, of the shares of Warrant
Stock to be above the amount payable therefor upon such exercise and (b) will
take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue or sell fully paid and non-assessable
shares of Warrant Stock upon the exercise of these Warrants.

         6.4 CERTIFICATE AS TO ADJUSTMENTS. In each case of an adjustment in the
number of shares of Warrant Stock receivable upon the exercise of these
Warrants, the Company will promptly compute such adjustment and mail to the
Holder a certificate, executed by an executive officer of the Company, setting
forth such adjustment and showing in detail the facts upon which such adjustment
is based.

         6.5 NOTICES OF RECORD  DATE If the  Company  takes a record of the
holders  of its Common  Stock for the purpose of:

         (a) entitling them to receive any dividend (other than a cash dividend
at the same rate as the

<PAGE>

rate of the last cash dividend theretofore paid) or other distribution, or any
right to subscribe for, purchase or otherwise acquire any shares of stock of any
class or any other securities, or to receive any other right;

         (b) any capital reorganization of the Company, any reclassification of
the capital stock of the Company, any consolidation or merger of the Company
with or into another Person, or any conveyance of all or substantially all of
the assets of the Company to another Person; or

         (c) any voluntary or involuntary dissolution, liquidation or winding up
of the Company; then, and in each such case, the Company shall mail to the
Holder a notice specifying, as the case may be, (I) the date on which a record
is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, or
(ii) the date on which such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding up is to take place, and
the time, if any, to be fixed, as to which the holders of record of Warrant
Stock (or such other securities at the time receivable upon the exercise of
these Warrants) shall be entitled to exchange their shares of Warrant Stock (or
such other securities) for securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding up.

         7. RESTRICTIONS ON TRANSFER OF WARRANTS AND WARRANT STOCK. The Warrant
Stock may not be sold, transferred or otherwise disposed of unless registered
under the Securities Act, and any applicable state securities laws or pursuant
to available exemptions from such registration, provided that the seller
delivers to the Company an opinion of counsel reasonably satisfactory to the
Company confirming the availability of such exemption. Notwithstanding the
foregoing, the restrictions imposed by this Section 9 shall cease and terminate
when (i) the Warrant Stock is sold or otherwise disposed of pursuant to an
effective registration statement under the Securities Act or the Warrant Stock
so transferred are not required to bear the legend pursuant to Section 8 or (ii)
the Holder has met the requirements for transfer of such Warrant Stock pursuant
to subparagraph (k) of Rule 144.

         8. LEGEND. Unless the shares of Warrant Stock have been registered
under the Securities Act, upon exercise of any of these Warrants and the
issuance of any of the shares of Warrant Stock, all certificates representing
such securities shall bear on the face thereof substantially the following
legend:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933 (THE "SECURITIES ACT") OR UNDER APPLICABLE STATE SECURITIES LAWS

         REGISTERED UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
         LAWS OR PURSUANT TO AVAILABLE EXEMPTIONS FROM SUCH REGISTRATION

PROVIDED, HOWEVER, that such legend shall not be required if in the opinion of
Company counsel registration of any future transfer is not required by the
applicable provisions of the Securities Act.

         9. NOTICES. All notices required hereunder shall be in writing and
shall be deemed given when telegraphed, delivered personally or within two days
after mailing when mailed by certified or registered mail, return receipt
requested, to the Company at its principal office, or to the Holder at the
address set forth on the record books of the Company, or at such other address
of which the Company or the Holder has been advised by notice in writing
hereunder.

in accordance with, the laws of the State of Florida, without giving effect to
conflicts of law principles.

are nontransferable and may not be assigned by the Holder in any manner. This
Warrant and any term hereof may be changed, waived, discharged or terminated
only by an instrument in writing signed by the party against which enforcement
