         The reporting person listed on the cover page to this Schedule 13D
hereby makes the following statement (this "Statement") pursuant to Section
13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and the rules and regulations promulgated thereunder.


ITEM 1.          SECURITY AND ISSUER.

         This Statement relates to the common stock, $.01 par value per share
(the "Common Stock"), of International Alliance Services, Inc., a Delaware
corporation formerly known as Republic Environmental Systems, Inc. (the
"Issuer").  The Issuer's principal executive office is located at 16 Sentry
Park West, 1787 Sentry Parkway West, Suite 400, Blue Bell, Pennsylvania 19422.


ITEM 2.          IDENTITY AND BACKGROUND.

         This Statement is being filed by H. Wayne Huizenga ("Mr. Huizenga")
whose business address is 200 South Andrews Ave., 6th Floor, Fort Lauderdale,
Florida 33301.  Mr. Huizenga is Chairman of the Board and Co-Chief Executive
Officer of Republic Industries, Inc., which is a holding company with major
business segments in integrated solid waste collection, disposal and recycling
services, electronic security services for commercial and residential use, and
vehicle retailing and related businesses and which is headquartered at 200 East
Las Olas Blvd., Suite 1400, Fort Lauderdale, Florida 33301.

         Mr. Huizenga is a citizen of the United States of America.  Mr.
Huizenga has not, during the last five years, (a) been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or (b) been a
party to any civil proceeding of a judicial or administrative body of competent
jurisdiction, and as a result of such proceeding was or is subject to a
judgment, decree, or final order enjoining future violations of, or prohibiting
or mandating activities subject to federal or state securities laws or finding
any violation with respect to such laws.


ITEM 3.          SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         On October 18, 1996, pursuant to a Stock Purchase Agreement, dated as
of May 19, 1996 (the "Purchase Agreement"), between the Issuer and Mr.
Huizenga, Mr. Huizenga acquired (a) 2,000,000 shares of Common Stock (the
"Shares"), (b) a Warrant to purchase 2,000,000 shares of Common Stock at an
exercise price of $2.625 per share, which is exercisable at any time from
October 18, 1996 until October 18, 1998, (c) a warrant to purchase 2,000,000
shares of Common Stock at an exercise price of $3.125 per share, which is
exercisable at any time from October 18, 1996 until October 18, 1999, and (d) a
warrant to purchase 2,000,000 shares of Common Stock
   4

at an exercise price of $3.875 per share, which is exercisable at any time from
October 18, 1996 until October 18, 2000 (collectively, items (b) through (d)
are referred to herein as the "Warrants").  The Purchase Agreement is
incorporated herein by reference as described in Item 7 and copies of the
Warrants are attached hereto as Exhibits 2 through 4 and are incorporated
herein by reference.  The description of the terms of the Purchase Agreement
and the Warrants set forth herein is qualified in its entirety by the terms of
the Purchase Agreement and the Warrants.

         Mr. Huizenga used personal funds to purchase the Shares and the
Warrants.  The total purchase price for the Shares and the Warrants was
$5,250,000.  Mr. Huizenga's source of funds for the exercise of the Warrants is
undetermined as of the date hereof, but most likely will come from personal
funds.


ITEM 4.          PURPOSE OF TRANSACTION.

         Mr. Huizenga acquired the Shares and Warrants for investment purposes
and, except as set forth herein, has no plans or proposals which relate to or
would result in any of the events or transactions described in Item 4(a)-(j) of
Schedule 13D.

         On October 18, 1996, the Issuer acquired, in merger transactions, all
of the outstanding shares of capital stock of Century Surety Company and
Commercial Surety Agency, Inc., each a wholly-owned subsidiary of Alliance
Holding Corporation ("Alliance").  In connection with such transactions, the
Issuer enlarged its board of directors to seven members and elected four new
members who were nominated by Alliance, including Mr. Richard C. Rochon, who
was recommended to Alliance by Mr. Huizenga.  In the future, Alliance is not
obligated to nominate any person recommended by Mr. Huizenga.

ITEM 5.          INTEREST IN SECURITIES OF THE ISSUER.

         (a) and (b)  As of October 18, 1996, Mr. Huizenga may be deemed to
beneficially own 8,000,000 shares of Common Stock (which includes 6,000,000
shares of Common Stock issuable upon exercise of the Warrants) representing
approximately 22.5% of the outstanding shares of Common Stock, calculated in
accordance with Rule 13d-3 under the Exchange Act (based on 29,618,158 shares
of Common Stock issued and outstanding as of October 22, 1996, plus the
6,000,000 shares of Common Stock issuable upon exercise of the Warrants which
Mr. Huizenga may be deemed to beneficially own and which are deemed outstanding
for purposes of this computation).  Mr. Huizenga has the sole power to vote and
the sole power to dispose of the 8,000,000 shares of Common Stock which he may
be deemed to beneficially own.

         (c)     Except with respect to the acquisition of the Shares and
Warrants described herein, there have been no other transactions in any
securities of the Issuer affected by Mr. Huizenga during the past 60 days.
   5

ITEM 6.          CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
                 RESPECT TO SECURITIES OF THE ISSUER.

         Except as described herein, Mr. Huizenga is not a party to any
contracts, arrangements, understandings or relationships with any person with
respect to securities of the Issuer.

         Pursuant to the Purchase Agreement (described in Item 3), the Issuer
has agreed to, as promptly as practicable after October 18, 1996, register the
Shares and the shares of Common Stock issuable upon exercise of the Warrants
pursuant to a registration statement to be filed with the Securities and
Exchange Commission.

                          SERIES A WARRANT CERTIFICATE
 
               To Purchase 2,000,000 Shares of Common Stock of:

                      REPUBLIC ENVIRONMENTAL SYSTEMS, INC.



         THIS IS TO CERTIFY THAT H. Wayne Huizenga (the "Holder") or Holder's
registered assigns, is entitled to purchase from REPUBLIC ENVIRONMENTAL
SYSTEMS, INC., a Delaware corporation (the "Company"), up to 2,000,000 shares
of the Company's common stock, par value $.01 per share (the "Common Stock"),
on the terms and conditions hereinafter set forth.


1        GRANT OF WARRANT

         1.1     GRANT.  The Company hereby grants the Holder Series A Warrants
to purchase 2,000,000 shares of Common Stock at a purchase price of $2.625 per
share (as adjusted from time to time pursuant to Section 2 hereof, the "Warrant
Price"), exercisable in whole or in part at any time and from time to time from
October 18, 1996 (the "Issue Date") until 6:00 p.m. on the date two years after
the Issue Date or, if such date is not a regular business day, on the next
occurring regular business day (as adjusted from time to time pursuant to
Section 2 hereof, the "Warrants" and the shares to be issued upon the exercise
thereof are "Warrant Shares").
   2

         1.2     SHARES TO BE ISSUED; RESERVATION OF SHARES.  The Company
covenants and agrees that (a) all Warrant Shares, upon issuance in accordance
with the terms hereof, and the payment of the purchase price therefor, will be
duly authorized, validly issued and outstanding, fully paid and non-assessable,
and free from all taxes, liens and charges with respect to the issuance thereof
other than those created by or arising through Holder, (b) the Company will
from time to time take all actions necessary to assure that the par value per
share of the Common Stock is at all times equal to or less than the applicable
Warrant Price, and (c) the Company will at all times during the exercise period
have authorized and reserved sufficient shares of Common Stock to provide for
the exercise of the Warrants in full.


2        ADJUSTMENTS TO WARRANT RIGHTS.  The number of Warrant Shares for which
Warrants are exercisable, and the Warrant Price of such shares shall be subject
to adjustment from time to time as set forth in this Section 2.  The Company
shall give Holder notice of any event described below which requires an
adjustment pursuant to this Section 2 within a reasonable period of time after
such event.

         2.1     STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any 
time the Company shall:

           2.1.1          take a record of the holders of its Common Stock for
         the purpose of entitling them to receive a dividend payable in, or
         other distribution of, additional shares of Common Stock,

           2.1.2          subdivide its outstanding shares of Common Stock into
         a larger number of shares of Common Stock, or

           2.1.3          combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock,

then (i) the number of Warrant Shares for which a Warrant is exercisable
immediately prior to the occurrence of any such event shall be adjusted to
equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which a Warrant is exercisable immediately
prior to the occurrence of such event would own or be entitled to receive after
the happening of such event and (ii) the Warrant Price immediately prior to the
occurrence of such event shall be adjusted to equal the product of the Warrant
Price multiplied by a fraction, the numerator of which shall be the number of
Warrant Shares for which a Warrant is exercisable immediately prior to the
adjustment and the denominator of which shall be the number of Warrant Shares
for which a Warrant is exercisable immediately after such adjustment.

         2.2     OTHER DIVIDENDS AND DISTRIBUTIONS.  If the Company shall make
or fix a record date for the holders of Common Stock entitled to receive a
dividend or other distribution payable in securities of the Company other than
shares of Common Stock, then lawful and adequate
   3

provision shall be made so that Holder shall be entitled to receive upon
exercise of the Warrants, for the aggregate Warrant Price in effect prior
thereto, in addition to the number of Warrant Shares immediately theretofore
issuable upon exercise of the Warrants, the kind and number of securities of
the Company which Holder would have owned and been entitled to receive had the
Warrants been exercised immediately prior to that date (pro rated in the case
of any partial exercise).

         2.3     RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.  If the Common
Stock is changed into the same or a different number of shares of any class or
classes of stock, whether by reclassification, exchange, substitution or
otherwise (other than a subdivision or combination of shares, stock dividend or
a reorganization, merger, consolidation or sale of assets, each as provided for
elsewhere in this Section 2) then the Holder of the Warrants shall be entitled
to receive upon exercise of the Warrants, in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrants, for the
aggregate Warrant Price in effect prior thereto, the kind and amount of stock
and other securities and property receivable upon such reclassification,
exchange, substitution or other change, which Holder would have been entitled
to receive had the Warrants been exercised immediately prior to such
reclassification, exchange, substitution or change (pro rated in the case of
any partial exercise).

         2.4     REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF ASSETS.
If any of the following transactions (each, a "Special Transaction") shall
become effective: (a) a capital reorganization (other than a dividend or other
distribution, subdivision, combination, reclassification, substitution or
exchange of shares provided for elsewhere in this Section 2), (b) a
consolidation or merger of the Company with and into another entity (where the
Company is not the surviving corporation or where there is a change in, or
distribution with respect to, the Common Stock), or (c) a sale or conveyance of
all or substantially all of the Company's assets, then, as a condition of the
Special Transaction, lawful and adequate provision shall be made so that Holder
shall thereafter have the right to purchase and receive upon exercise of the
Warrants, in lieu of the Warrant Shares immediately theretofore issuable upon
exercise of the Warrants, for the aggregate Warrant Price in effect immediately
prior to such consummation, such shares of stock, other securities, cash or
other assets ("Other Property") as may be issued or paid pursuant to the terms
of such Special Transaction to the holders of shares of Common Stock for which
such Warrants could have been exercised immediately prior to such Special
Transaction (pro rated in the case of any partial exercises).  In connection
with any Special Transaction, appropriate provision shall be made with respect
to the rights and interests of Holder to the end that the provisions of the
Warrants (including without limitation provisions for adjustment of the Warrant
Price and the number of Warrant Shares issuable upon the exercise of the
Warrants), shall thereafter be applicable, as nearly as may be practicable, to
any Other Property thereafter deliverable upon the exercise of the Warrants.
The Company shall not effect any Special Transaction unless prior to, or
simultaneously with, the closing, the successor entity (if other than the
Company), if any, resulting from such consolidation or merger or the entity
acquiring such assets shall assume by a written instrument executed and mailed
by certified mail or delivered to Holder at the address of Holder appearing on
the books of the Company, the obligation of the
   4

Company or such successor corporation to deliver to Holder such Other Property,
as in accordance with the foregoing provisions, which Holder shall have the
right to purchase.

         2.5     SALES BELOW CURRENT MARKET VALUE.

           2.5.1          Excluding shares, rights, options, warrants or
         convertible or exchangeable securities issued in any of the
         transactions described in Sections 2.1, 2.2, 2.3 or 2.4 above, in the
         event the Company shall (i) sell and issue shares of Common Stock at a
         price per share lower than the Current Market Price (defined below) or
         (ii) sell or issue rights, options, warrants or convertible or
         exchangeable securities containing the right to subscribe for or
         purchase shares of Common Stock and the price per share for which
         Common Stock is issuable upon the exercise, exchange or conversion of
         such rights, options, warrants or convertible or exchangeable
         securities shall be less than the Current Market Price, then the
         Warrant Price shall be reduced to a price determined by multiplying
         the Warrant Price by a fraction (i) the numerator of which shall equal
         the sum of (a) the number of shares of Common Stock outstanding at the
         close of business on the date immediately prior to the date of such
         issuance or sale plus (b) the number of shares of Common Stock that
         the maximum aggregate consideration received by the Company to effect
         such issuance or sale of Common Stock or the exercise, conversion or
         exchange of all of such rights, options, warrants or convertible or
         exchangeable securities into shares of Common Stock would purchase at
         the Warrant Price, and (ii) the denominator of which shall equal the
         number of shares of Common Stock outstanding at the close of business
         on the date of such issuance after giving effect to such issuance.
         For purposes of this Agreement, Current Market Price shall mean, in
         respect of any share of Common Stock on any date herein specified, (a)
         if there shall then be a public market for the Common Stock, the
         average of the daily market prices for 10 consecutive business days
         commencing 25 days before such date; the daily market price for each
         such business day being (i) the last sale price on such day on the
         Nasdaq National Market ("Nasdaq") or principal stock exchange on which
         such Common Stock is then listed, (ii) if no sale takes place on such
         day on any such exchange, the average of the last reported closing bid
         and asked prices on such day as officially quoted on Nasdaq or such
         principal exchange, (iii) if the Common Stock is not then listed or
         admitted to trading on Nasdaq or any stock exchange, the average of
         the last reported closing bid and asked prices on such day in the
         over-the-counter market, as furnished by the quotation systems upon
         which the Common Stock is then quoted, provided that such quotation
         systems are operated by the National Association of Securities Dealers
         ("NASD") or its affiliates or the National Quotation Bureau, Inc. or
         its affiliates, (iv) if none of such entities at the time is engaged
         in the business of reporting such prices, as furnished by any similar
         firm then engaged in such business, or (v) if there is no such firm,
         as furnished by any member of the NASD selected by the Company; or (b)
         at any time that there is no public market for the Common Stock, the
         fair market value per share of Common Stock on such date as determined
         in good faith by the Board of Directors of the Company.
   5

           2.5.2          For the purpose of making any adjustment required
         under this Section 2.5, the consideration received by the Company for
         any issue or sale of securities shall (a) if it consists of cash, be
         computed as the net amount of cash received by the Company after
         deduction of any expenses payable by the Company and any underwriting
         or similar commissions, compensation or concession in connection with
         such issue or sale, (b) if it consists of property other than cash, be
         computed at the fair value of that property as determined by the
         Company's Board of Directors in good faith, (c) if such shares of
         Common Stock or rights, options, warrants or convertible securities
         are issued or sold together with other stock or securities or other
         assets of the Company for a consideration which covers both, be
         computed as that portion of the consideration so received that may be
         reasonably determined by the Board of Directors of the Company in good
         faith to be allocated to such shares of Common Stock, or rights,
         options, warrants or convertible or exchangeable securities, and (d)
         if the issuance shall be of such rights, options, warrants or
         convertible or exchangeable securities to purchase Common Stock, be
         determined by dividing (x) the total amount receivable by the Company
         in consideration of the sale and issuance of such rights, options,
         warrants or convertible or exchangeable securities, plus the total
         consideration payable to the Company upon exercise, conversion or
         exchange thereof by (y) the total number of shares of Common Stock
         covered by such rights, options, warrants or convertible or
         exchangeable securities.

           2.5.3          Upon each adjustment of the Warrant Price per Warrant
         Share pursuant to Section 2.5.1, the Warrants shall thereupon evidence
         the right to purchase that number of shares of Common Stock
         (calculated to the nearest hundredth of a share) equal to (a) the
         product of (i) the number of shares of Common Stock for which a
         Warrant is exercisable immediately prior to such adjustment multiplied
         by (ii) the Warrant Price in effect immediately prior to such
         adjustment divided by (b) the Warrant Price in effect immediately
         after such adjustment.

           2.5.4          No further adjustments under this Section 2.5 shall
         be made upon the actual issuance of such Common Stock or upon exercise
         or conversion of such warrants, rights, options or convertible or
         exchangeable securities causing any adjustment under this Section 2.5.

         2.6     LIQUIDATION.  If the Company shall, at any time, prior to the
expiration of the Warrants, dissolve, liquidate or wind up its affairs, Holder
shall have the right, but not the obligation, to exercise the Warrants.  Upon
such exercise, Holder shall have the right to receive, in lieu of the shares of
Common Stock that Holder otherwise would have been entitled to receive upon
such exercise, the same kind and amount of assets as would have been issued,
distributed or paid to Holder upon any such dissolution, liquidation or winding
up with respect to such shares of Common Stock had Holder been the holder of
record of such shares of Common Stock receivable upon exercise of the Warrants
on the date for determining those entitled to receive any such distribution.
If any such dissolution, liquidation or winding up results in any cash
   6

distribution in excess of the Warrant Price, Holder may, at Holder's option,
exercise the Warrants without making payment of the applicable Warrant Price
and, in such case, the Company shall, upon distribution to Holder, consider the
applicable Warrant Price per Warrant Share to have been paid in full, and in
making settlement to Holder shall deduct an amount equal to the applicable
Warrant Price from the amount payable to Holder.

         2.7     NOTICE.  Whenever the Warrants or the number of Warrant Shares
issuable hereunder is to be adjusted as provided herein or a dividend or
distribution (in cash, stock or otherwise and including, without limitation,
any distributions under Section 2.6) is to be declared by the Company, or a
definitive agreement with respect to a Special Transaction has been entered
into, the Company shall forthwith cause to be sent to the Holder at the last
address of the Holder shown on the books of the Company, by first-class mail,
postage prepaid, at least ten (10) days prior to the record date specified in
(a) below or at least twenty (20) days before the date specified in (b) below,
a notice stating in reasonable detail the relevant facts and any resulting
adjustments and the calculation thereof, if applicable, and stating (if
applicable):

           2.7.1          the date to be used to determine (a) which holders of
         Common Stock will be entitled to receive notice of such dividend,
         distribution, subdivision or combination (the "Record Date"), and (b)
         the date as of which such dividend distribution, subdivision or
         combination shall be made; or, if a record is not to be taken, the
         date as of which the holders of Common Stock of record to be entitled
         to such dividend, distribution, subdivision or combination are to be
         determined (provided, that in the event the Company institutes a
         policy of declaring cash dividends on a periodic basis, the Company
         need only provide the relevant information called for in this Section
         2.7.1 with respect to the first cash dividend payment to be made
         pursuant to such policy and thereafter provide only notice of any
         changes in the amount or the frequency of any subsequent dividend
         payments), or

           2.7.2          the date on which a Special Transaction is expected
         to become effective, and the date as of which it is expected that
         holders of Common Stock of record shall be entitled to exchange their
         shares of Common Stock for securities or other property deliverable
         upon consummation of the Special Transaction (the "Exchange Date").

         2.8     FRACTIONAL INTERESTS.  The Company shall not be required to
issue fractions of shares of Common Stock upon the exercise of a Warrant. If
any fraction of a share of Common Stock would be issuable upon the exercise of
a Warrant, the Company shall, upon such issuance, purchase such fraction for an
amount in cash equal to the current value of such fraction, computed on the
basis of the Current Market Price on the last business day prior to the date of
exercise.

         2.9     EFFECT OF ALTERNATE SECURITIES.  If at any time, as a result
of an adjustment made pursuant to this Section 2, Holder shall become entitled
to receive any securities of the Company other than shares of Common Stock,
then the number of such other securities receivable upon exercise of the
Warrants shall be subject to adjustment from time to time on terms as nearly
   7

equivalent as practicable to the provisions with respect to shares of Common
Stock contained in this Section 2.

         2.10    SUCCESSIVE APPLICATION.  The provisions of this Section 2
shall similarly apply from time to time to successive events covered by this
Section 2.

         2.11    WHEN ADJUSTMENTS ARE TO BE MADE.  The adjustments required by
this Section 2 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment to the number
of shares for which the Warrants are exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination
of shares of the Common Stock, as provided for in Section 2.1) up to, but not
beyond, the date and time of exercise of any Warrants if such adjustment either
by itself or with other adjustments not previously made adds or subtracts less
than 1% to the number of shares of Common Stock for which the Warrants
initially issued pursuant to this Agreement are exercisable immediately prior
to the making of such adjustment.  Any adjustment representing a change of less
than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 2 and not previously made, would result in
a minimum adjustment or on the date of exercise.  For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close
of business on the date of its occurrence.

         2.12    WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling then to
receive a dividend or distribution or subscription or purchase rights and
shall, thereafter and before the distribution to stockholders thereof, legally
abandon its plan to pay or deliver such dividend, distribution, subscription or
purchase rights, then thereafter no adjustment shall be required by reason of
the taking of such record and any such adjustment previously made in respect
thereof shall be rescinded and annulled.

         2.13    SUPERSEDING ADJUSTMENT.  If, at any time after any adjustment
of the Warrant Price shall have been made pursuant to Section 2.6 as the result
of any issuance of warrants, options, rights or convertible or exchangeable
securities, and such warrants, options or rights, or the right of conversion or
exchange in such other convertible or exchangeable securities, shall expire,
and all or a portion of such warrants, options or rights, or the right of
conversion or exchange with respect to all or a portion of such other
convertible or exchangeable securities, as the case may be, shall not have been
exercised, then such previous adjustment shall be rescinded and annulled and,
if applicable, the Warrant Price shall be recalculated as if all such expired
and unexercised warrants, options, rights or convertible or exchangeable
securities had never been issued.

3        EXERCISE

         3.1     EXERCISE OF WARRANT.

           3.1.1          Holder may exercise a Warrant by (i) surrendering
         this Warrant Certificate, with the form of exercise notice attached
         hereto as Exhibit "A" duly executed by Holder, and (ii) making payment
         to the Company of the aggregate Warrant Price for the applicable
         Warrant Shares in cash, by certified check, bank check or wire
         transfer to an account designated by the Company.  Upon any partial
         exercise of the Warrants, the Company, at its expense, shall promptly
         issue to Holder for its surrendered Warrant Certificate a replacement
         Warrant Certificate identical in all respects to this Warrant
         Certificate, except that the number of Warrant Shares shall be reduced
         accordingly.

           3.1.2          Each person in whose name any Warrant Share
         certificate is issued upon exercise of any Warrants shall for all
         purposes be deemed to have become the holder of record of the Warrant
         Shares for which such Warrant was exercised, and such Warrant Share
         certificate shall be dated the date upon which the Warrant exercise
         notice was duly surrendered and payment of the purchase price was
         tendered to the Company.

         3.2     ISSUANCE OF WARRANT SHARES.  The Warrant Shares purchased
shall be issued to the holder exercising the Warrants as of the close of
business on the date on which all actions and payments required to be taken or
made by Holder, pursuant to Section 3.1, shall have been so taken or made.
Certificates for the Warrant Shares so purchased shall be delivered to Holder
within 10 days after the Warrants are surrendered.


4        RIGHTS OF HOLDER

         4.1     RIGHTS PRIOR TO EXERCISE.  Holder shall not, solely by virtue
of the Warrants and prior to the issuance of the Warrant Shares upon due
exercise thereof, be entitled to any rights of a shareholder in the Company.

         4.2     ISSUANCE OF WARRANT SHARES.  The Company shall not by any
action including, without limitation, amending its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of the
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 actions as may be necessary or
appropriate to protect the rights of Holder against impairment.  Without
limiting the generality of the foregoing, the Company will (a) take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of the Warrants and (b) use its best efforts to obtain all such
authorizations, exemptions or consents from any public
   9

regulatory body having jurisdiction thereof as may be necessary to enable the
company to perform its obligations with respect to the Warrants.

         Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form satisfactory
to Holder, the continuing validity of the Warrants and the obligations of the
Company hereunder.


5        TRANSFERABILITY

         Holder may sell, assign, transfer or otherwise dispose of all or any
portion of the Warrants or the Warrant Shares acquired upon any exercise hereof
at any time and from time to time.  Upon the sale, assignment, transfer or
other disposition of all or any portion of the Warrants, Holder shall deliver
to Company a written notice of such in the form attached hereto as Exhibit B
duly executed by Holder which includes the identity and address of any
purchaser, assignor or transferee.


6        LEGEND ON WARRANT SHARES

         Certificates evidencing the Warrant Shares shall bear the following
legend until such time as the Warrant Shares are duly registered for resale:

charges shall be paid by Holder.  The Company shall not be required, however,
to pay any tax or other charge imposed in connection with any transfer involved
in the issue of any certificate for Warrant Shares in any name other than that

                          SERIES B WARRANT CERTIFICATE

                To Purchase 2,000,000 Shares of Common Stock of:

                      REPUBLIC ENVIRONMENTAL SYSTEMS, INC.



         THIS IS TO CERTIFY THAT H. Wayne Huizenga (the "Holder") or Holder's
registered assigns, is entitled to purchase from REPUBLIC ENVIRONMENTAL
SYSTEMS, INC., a Delaware corporation (the "Company"), up to 2,000,000 shares
of the Company's common stock, par value $.01 per share (the "Common Stock"),
on the terms and conditions hereinafter set forth.


1        GRANT OF WARRANT

         1.1     GRANT.  The Company hereby grants the Holder Series C Warrants
to purchase 2,000,000 shares of Common Stock at a purchase price of $3.125 per
share (as adjusted from time to time pursuant to Section 2 hereof, the "Warrant
Price"), exercisable in whole or in part at any time and from time to time from
October 18, 1996 (the "Issue Date") until 6:00 p.m. on the date three years
after the Issue Date or, if such date is not a regular business day, on the
next occurring regular business day (as adjusted from time to time pursuant to
Section 2 hereof, the "Warrants" and the shares to be issued upon the exercise
thereof are "Warrant Shares").
   2

         1.2     SHARES TO BE ISSUED; RESERVATION OF SHARES.  The Company
covenants and agrees that (a) all Warrant Shares, upon issuance in accordance
with the terms hereof, and the payment of the purchase price therefor, will be
duly authorized, validly issued and outstanding, fully paid and non-assessable,
and free from all taxes, liens and charges with respect to the issuance thereof
other than those created by or arising through Holder, (b) the Company will
from time to time take all actions necessary to assure that the par value per
share of the Common Stock is at all times equal to or less than the applicable
Warrant Price, and (c) the Company will at all times during the exercise period
have authorized and reserved sufficient shares of Common Stock to provide for
the exercise of the Warrants in full.


2        ADJUSTMENTS TO WARRANT RIGHTS.  The number of Warrant Shares for which
Warrants are exercisable, and the Warrant Price of such shares shall be subject
to adjustment from time to time as set forth in this Section 2.  The Company
shall give Holder notice of any event described below which requires an
adjustment pursuant to this Section 2 within a reasonable period of time after
such event.

         2.1     STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any
time the Company shall:

                 2.1.1     take a record of the holders of its Common Stock for
         the purpose of entitling them to receive a dividend payable in, or
         other distribution of, additional shares of Common Stock,

                 2.1.2     subdivide its outstanding shares of Common Stock
         into a larger number of shares of Common Stock, or

                 2.1.3     combine its outstanding shares of Common Stock into
         a smaller number of shares of Common Stock,

then (i) the number of Warrant Shares for which a Warrant is exercisable
immediately prior to the occurrence of any such event shall be adjusted to
equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which a Warrant is exercisable immediately
prior to the occurrence of such event would own or be entitled to receive after
the happening of such event and (ii) the Warrant Price immediately prior to the
occurrence of such event shall be adjusted to equal the product of the Warrant
Price multiplied by a fraction, the numerator of which shall be the number of
Warrant Shares for which a Warrant is exercisable immediately prior to the
adjustment and the denominator of which shall be the number of Warrant Shares
for which a Warrant is exercisable immediately after such adjustment.

         2.2     OTHER DIVIDENDS AND DISTRIBUTIONS.  If the Company shall make
or fix a record date for the holders of Common Stock entitled to receive a
dividend or other distribution payable in securities of the Company other than
shares of Common Stock, then lawful and adequate
   3

provision shall be made so that Holder shall be entitled to receive upon
exercise of the Warrants, for the aggregate Warrant Price in effect prior
thereto, in addition to the number of Warrant Shares immediately theretofore
issuable upon exercise of the Warrants, the kind and number of securities of
the Company which Holder would have owned and been entitled to receive had the
Warrants been exercised immediately prior to that date (pro rated in the case
of any partial exercise).

         2.3     RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.  If the Common
Stock is changed into the same or a different number of shares of any class or
classes of stock, whether by reclassification, exchange, substitution or
otherwise (other than a subdivision or combination of shares, stock dividend or
a reorganization, merger, consolidation or sale of assets, each as provided for
elsewhere in this Section 2) then the Holder of the Warrants shall be entitled
to receive upon exercise of the Warrants, in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrants, for the
aggregate Warrant Price in effect prior thereto, the kind and amount of stock
and other securities and property receivable upon such reclassification,
exchange, substitution or other change, which Holder would have been entitled
to receive had the Warrants been exercised immediately prior to such
reclassification, exchange, substitution or change (pro rated in the case of
any partial exercise).

         2.4     REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF ASSETS.
If any of the following transactions (each, a "Special Transaction") shall
become effective: (a) a capital reorganization (other than a dividend or other
distribution, subdivision, combination, reclassification, substitution or
exchange of shares provided for elsewhere in this Section 2), (b) a
consolidation or merger of the Company with and into another entity (where the
Company is not the surviving corporation or where there is a change in, or
distribution with respect to, the Common Stock), or (c) a sale or conveyance of
all or substantially all of the Company's assets, then, as a condition of the
Special Transaction, lawful and adequate provision shall be made so that Holder
shall thereafter have the right to purchase and receive upon exercise of the
Warrants, in lieu of the Warrant Shares immediately theretofore issuable upon
exercise of the Warrants, for the aggregate Warrant Price in effect immediately
prior to such consummation, such shares of stock, other securities, cash or
other assets ("Other Property") as may be issued or paid pursuant to the terms
of such Special Transaction to the holders of shares of Common Stock for which
such Warrants could have been exercised immediately prior to such Special
Transaction (pro rated in the case of any partial exercises).  In connection
with any Special Transaction, appropriate provision shall be made with respect
to the rights and interests of Holder to the end that the provisions of the
Warrants (including without limitation provisions for adjustment of the Warrant
Price and the number of Warrant Shares issuable upon the exercise of the
Warrants), shall thereafter be applicable, as nearly as may be practicable, to
any Other Property thereafter deliverable upon the exercise of the Warrants.
The Company shall not effect any Special Transaction unless prior to, or
simultaneously with, the closing, the successor entity (if other than the
Company), if any, resulting from such consolidation or merger or the entity
acquiring such assets shall assume by a written instrument executed and mailed
by certified mail or delivered to Holder at the address of Holder appearing on
the books of the Company, the obligation of the
   4

Company or such successor corporation to deliver to Holder such Other Property,
as in accordance with the foregoing provisions, which Holder shall have the
right to purchase.

         2.5     SALES BELOW CURRENT MARKET VALUE.

           2.5.1          Excluding shares, rights, options, warrants or
         convertible or exchangeable securities issued in any of the
         transactions described in Sections 2.1, 2.2, 2.3 or 2.4 above, in the
         event the Company shall (i) sell and issue shares of Common Stock at a
         price per share lower than the Current Market Price (defined below) or
         (ii) sell or issue rights, options, warrants or convertible or
         exchangeable securities containing the right to subscribe for or
         purchase shares of Common Stock and the price per share for which
         Common Stock is issuable upon the exercise, exchange or conversion of
         such rights, options, warrants or convertible or exchangeable
         securities shall be less than the Current Market Price, then the
         Warrant Price shall be reduced to a price determined by multiplying
         the Warrant Price by a fraction (i) the numerator of which shall equal
         the sum of (a) the number of shares of Common Stock outstanding at the
         close of business on the date immediately prior to the date of such
         issuance or sale plus (b) the number of shares of Common Stock that
         the maximum aggregate consideration received by the Company to effect
         such issuance or sale of Common Stock or the exercise, conversion or
         exchange of all of such rights, options, warrants or convertible or
         exchangeable securities into shares of Common Stock would purchase at
         the Warrant Price, and (ii) the denominator of which shall equal the
         number of shares of Common Stock outstanding at the close of business
         on the date of such issuance after giving effect to such issuance.
         For purposes of this Agreement, Current Market Price shall mean, in
         respect of any share of Common Stock on any date herein specified, (a)
         if there shall then be a public market for the Common Stock, the
         average of the daily market prices for 10 consecutive business days
         commencing 25 days before such date; the daily market price for each
         such business day being (i) the last sale price on such day on the
         Nasdaq National Market ("Nasdaq") or principal stock exchange on which
         such Common Stock is then listed, (ii) if no sale takes place on such
         day on any such exchange, the average of the last reported closing bid
         and asked prices on such day as officially quoted on Nasdaq or such
         principal exchange, (iii) if the Common Stock is not then listed or 
         admitted to trading on Nasdaq or any stock exchange, the average
         of the last reported closing bid and asked prices on such day in the
         over-the-counter market, as furnished by the quotation systems upon 
         which the Common Stock is then quoted, provided that such quotation 
         systems are operated by the National Association of Securities Dealers 
         ("NASD") or its affiliates or the National Quotation Bureau, Inc. or 
         its affiliates, (iv) if none of such entities at the time is engaged 
         in the business of reporting such prices, as furnished by any similar 
         firm then engaged in such business, or (v) if there is no such firm, 
         as furnished by any member of the NASD selected by the Company; or (b) 
         at any time that there is no public market for the Common Stock, the
         fair market value per share of Common Stock on such date as determined 
         in good faith by the Board of Directors of the Company.

           2.5.2          For the purpose of making any adjustment required
         under this Section 2.5, the consideration received by the Company for
         any issue or sale of securities shall (a) if it consists of cash, be
         computed as the net amount of cash received by the Company after
         deduction of any expenses payable by the Company and any underwriting
         or similar commissions, compensation or concession in connection with
         such issue or sale, (b) if it consists of property other than cash, be
         computed at the fair value of that property as determined by the
         Company's Board of Directors in good faith, (c) if such shares of
         Common Stock or rights, options, warrants or convertible securities
         are issued or sold together with other stock or securities or other
         assets of the Company for a consideration which covers both, be
         computed as that portion of the consideration so received that may be
         reasonably determined by the Board of Directors of the Company in good
         faith to be allocated to such shares of Common Stock, or rights,
         options, warrants or convertible or exchangeable securities, and (d)
         if the issuance shall be of such rights, options, warrants or
         convertible or exchangeable securities to purchase Common Stock, be
         determined by dividing (x) the total amount receivable by the Company
         in consideration of the sale and issuance of such rights, options,
         warrants or convertible or exchangeable securities, plus the total
         consideration payable to the Company upon exercise, conversion or
         exchange thereof by (y) the total number of shares of Common Stock
         covered by such rights, options, warrants or convertible or
         exchangeable securities.

           2.5.3          Upon each adjustment of the Warrant Price per Warrant
         Share pursuant to Section 2.5.1, the Warrants shall thereupon evidence
         the right to purchase that number of shares of Common Stock
         (calculated to the nearest hundredth of a share) equal to (a) the
         product of (i) the number of shares of Common Stock for which a
         Warrant is exercisable immediately prior to such adjustment multiplied
         by (ii) the Warrant Price in effect immediately prior to such
         adjustment divided by (b) the Warrant Price in effect immediately
         after such adjustment.

           2.5.4          No further adjustments under this Section 2.5 shall
         be made upon the actual issuance of such Common Stock or upon exercise
         or conversion of such warrants, rights, options or convertible or
         exchangeable securities causing any adjustment under this Section 2.5.

         2.6     LIQUIDATION.  If the Company shall, at any time, prior to the
expiration of the Warrants, dissolve, liquidate or wind up its affairs, Holder
shall have the right, but not the obligation, to exercise the Warrants.  Upon
such exercise, Holder shall have the right to receive, in lieu of the shares of
Common Stock that Holder otherwise would have been entitled to receive upon
such exercise, the same kind and amount of assets as would have been issued,
distributed or paid to Holder upon any such dissolution, liquidation or winding
up with respect to such shares of Common Stock had Holder been the holder of
record of such shares of Common Stock receivable upon exercise of the Warrants
on the date for determining those entitled to receive any such distribution.
If any such dissolution, liquidation or winding up results in any cash
   6

distribution in excess of the Warrant Price, Holder may, at Holder's option,
exercise the Warrants without making payment of the applicable Warrant Price
and, in such case, the Company shall, upon distribution to Holder, consider the
applicable Warrant Price per Warrant Share to have been paid in full, and in
making settlement to Holder shall deduct an amount equal to the applicable
Warrant Price from the amount payable to Holder.

         2.7     NOTICE.  Whenever the Warrants or the number of Warrant Shares
issuable hereunder is to be adjusted as provided herein or a dividend or
distribution (in cash, stock or otherwise and including, without limitation,
any distributions under Section 2.6) is to be declared by the Company, or a
definitive agreement with respect to a Special Transaction has been entered
into, the Company shall forthwith cause to be sent to the Holder at the last
address of the Holder shown on the books of the Company, by first-class mail,
postage prepaid, at least ten (10) days prior to the record date specified in
(a) below or at least twenty (20) days before the date specified in (b) below,
a notice stating in reasonable detail the relevant facts and any resulting
adjustments and the calculation thereof, if applicable, and stating (if
applicable):

           2.7.1          the date to be used to determine (a) which holders of
         Common Stock will be entitled to receive notice of such dividend,
         distribution, subdivision or combination (the "Record Date"), and (b)
         the date as of which such dividend distribution, subdivision or
         combination shall be made; or, if a record is not to be taken, the
         date as of which the holders of Common Stock of record to be entitled
         to such dividend, distribution, subdivision or combination are to be
         determined (provided, that in the event the Company institutes a
         policy of declaring cash dividends on a periodic basis, the Company
         need only provide the relevant information called for in this Section
         2.7.1 with respect to the first cash dividend payment to be made
         pursuant to such policy and thereafter provide only notice of any
         changes in the amount or the frequency of any subsequent dividend
         payments), or

           2.7.2          the date on which a Special Transaction is expected
         to become effective, and the date as of which it is expected that
         holders of Common Stock of record shall be entitled to exchange their
         shares of Common Stock for securities or other property deliverable
         upon consummation of the Special Transaction (the "Exchange Date").

         2.8     FRACTIONAL INTERESTS.  The Company shall not be required to
issue fractions of shares of Common Stock upon the exercise of a Warrant. If
any fraction of a share of Common Stock would be issuable upon the exercise of
a Warrant, the Company shall, upon such issuance, purchase such fraction for an
amount in cash equal to the current value of such fraction, computed on the
basis of the Current Market Price on the last business day prior to the date of
exercise.

         2.9     EFFECT OF ALTERNATE SECURITIES.  If at any time, as a result
of an adjustment made pursuant to this Section 2, Holder shall become entitled
to receive any securities of the Company other than shares of Common Stock,
then the number of such other securities receivable upon exercise of the
Warrants shall be subject to adjustment from time to time on terms as nearly
   7

equivalent as practicable to the provisions with respect to shares of Common
Stock contained in this Section 2.

         2.10    SUCCESSIVE APPLICATION.  The provisions of this Section 2
shall similarly apply from time to time to successive events covered by this
Section 2.

         2.11    WHEN ADJUSTMENTS ARE TO BE MADE.  The adjustments required by
this Section 2 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment to the number
of shares for which the Warrants are exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination
of shares of the Common Stock, as provided for in Section 2.1) up to, but not
beyond, the date and time of exercise of any Warrants if such adjustment either
by itself or with other adjustments not previously made adds or subtracts less
than 1% to the number of shares of Common Stock for which the Warrants
initially issued pursuant to this Agreement are exercisable immediately prior
to the making of such adjustment.  Any adjustment representing a change of less
than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 2 and not previously made, would result in
a minimum adjustment or on the date of exercise.  For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close
of business on the date of its occurrence.

         2.12    WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling then to
receive a dividend or distribution or subscription or purchase rights and
shall, thereafter and before the distribution to stockholders thereof, legally
abandon its plan to pay or deliver such dividend, distribution, subscription or
purchase rights, then thereafter no adjustment shall be required by reason of
the taking of such record and any such adjustment previously made in respect
thereof shall be rescinded and annulled.

         2.13    SUPERSEDING ADJUSTMENT.  If, at any time after any adjustment
of the Warrant Price shall have been made pursuant to Section 2.6 as the result
of any issuance of warrants, options, rights or convertible or exchangeable
securities, and such warrants, options or rights, or the right of conversion or
exchange in such other convertible or exchangeable securities, shall expire,
and all or a portion of such warrants, options or rights, or the right of
conversion or exchange with respect to all or a portion of such other
convertible or exchangeable securities, as the case may be, shall not have been
exercised, then such previous adjustment shall be rescinded and annulled and,
if applicable, the Warrant Price shall be recalculated as if all such expired
and unexercised warrants, options, rights or convertible or exchangeable
securities had never been issued.

3        EXERCISE

         3.1     EXERCISE OF WARRANT.

           3.1.1          Holder may exercise a Warrant by (i) surrendering
         this Warrant Certificate, with the form of exercise notice attached
         hereto as Exhibit "A" duly executed by Holder, and (ii) making payment
         to the Company of the aggregate Warrant Price for the applicable
         Warrant Shares in cash, by certified check, bank check or wire
         transfer to an account designated by the Company.  Upon any partial
         exercise of the Warrants, the Company, at its expense, shall promptly
         issue to Holder for its surrendered Warrant Certificate a replacement
         Warrant Certificate identical in all respects to this Warrant
         Certificate, except that the number of Warrant Shares shall be reduced
         accordingly.

           3.1.2          Each person in whose name any Warrant Share
         certificate is issued upon exercise of any Warrants shall for all
         purposes be deemed to have become the holder of record of the Warrant
         Shares for which such Warrant was exercised, and such Warrant Share
         certificate shall be dated the date upon which the Warrant exercise
         notice was duly surrendered and payment of the purchase price was
         tendered to the Company.

         3.2     ISSUANCE OF WARRANT SHARES.  The Warrant Shares purchased
shall be issued to the holder exercising the Warrants as of the close of
business on the date on which all actions and payments required to be taken or
made by Holder, pursuant to Section 3.1, shall have been so taken or made.
Certificates for the Warrant Shares so purchased shall be delivered to Holder
within 10 days after the Warrants are surrendered.


4        RIGHTS OF HOLDER

         4.1     RIGHTS PRIOR TO EXERCISE.  Holder shall not, solely by virtue
of the Warrants and prior to the issuance of the Warrant Shares upon due
exercise thereof, be entitled to any rights of a shareholder in the Company.

         4.2     ISSUANCE OF WARRANT SHARES.  The Company shall not by any
action including, without limitation, amending its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of the
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 actions as may be necessary or
appropriate to protect the rights of Holder against impairment.  Without
limiting the generality of the foregoing, the Company will (a) take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of the Warrants and (b) use its best efforts to obtain all such
authorizations, exemptions or consents from any public
   9

regulatory body having jurisdiction thereof as may be necessary to enable the
company to perform its obligations with respect to the Warrants.

         Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form satisfactory
to Holder, the continuing validity of the Warrants and the obligations of the
Company hereunder.


5        TRANSFERABILITY

         Holder may sell, assign, transfer or otherwise dispose of all or any
portion of the Warrants or the Warrant Shares acquired upon any exercise hereof
at any time and from time to time.  Upon the sale, assignment, transfer or
other disposition of all or any portion of the Warrants, Holder shall deliver
to Company a written notice of such in the form attached hereto as Exhibit B
duly executed by Holder which includes the identity and address of any
purchaser, assignor or transferee.


6        LEGEND ON WARRANT SHARES

         Certificates evidencing the Warrant Shares shall bear the following
legend until such time as the Warrant Shares are duly registered for resale:

                          SERIES C WARRANT CERTIFICATE

                To Purchase 2,000,000 Shares of Common Stock of:

                      REPUBLIC ENVIRONMENTAL SYSTEMS, INC.


         THIS IS TO CERTIFY THAT H. Wayne Huizenga (the "Holder") or Holder's
registered assigns, is entitled to purchase from REPUBLIC ENVIRONMENTAL
SYSTEMS, INC., a Delaware corporation (the "Company"), up to 2,000,000 shares
of the Company's common stock, par value $.01 per share (the "Common Stock"),
on the terms and conditions hereinafter set forth.


1        GRANT OF WARRANT

         1.1     GRANT.  The Company hereby grants the Holder Series C Warrants
to purchase 2,000,000 shares of Common Stock at a purchase price of $3.875 per
share (as adjusted from time to time pursuant to Section 2 hereof, the "Warrant
Price"), exercisable in whole or in part at any time and from time to time from
October 18, 1996 (the "Issue Date") until 6:00 p.m. on the date four years
after the Issue Date or, if such date is not a regular business day, on the
next occurring regular business day (as adjusted from time to time pursuant to
Section 2 hereof, the "Warrants" and the shares to be issued upon the exercise
thereof are "Warrant Shares").
   2

         1.2     SHARES TO BE ISSUED; RESERVATION OF SHARES.  The Company
covenants and agrees that (a) all Warrant Shares, upon issuance in accordance
with the terms hereof, and the payment of the purchase price therefor, will be
duly authorized, validly issued and outstanding, fully paid and non-assessable,
and free from all taxes, liens and charges with respect to the issuance thereof
other than those created by or arising through Holder, (b) the Company will
from time to time take all actions necessary to assure that the par value per
share of the Common Stock is at all times equal to or less than the applicable
Warrant Price, and (c) the Company will at all times during the exercise period
have authorized and reserved sufficient shares of Common Stock to provide for
the exercise of the Warrants in full.


2        ADJUSTMENTS TO WARRANT RIGHTS.  The number of Warrant Shares for which
Warrants are exercisable, and the Warrant Price of such shares shall be subject
to adjustment from time to time as set forth in this Section 2.  The Company
shall give Holder notice of any event described below which requires an
adjustment pursuant to this Section 2 within a reasonable period of time after
such event.

         2.1     STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS.  If at any
time the Company shall:

           2.1.1          take a record of the holders of its Common Stock for
         the purpose of entitling them to receive a dividend payable in, or
         other distribution of, additional shares of Common Stock,

           2.1.2          subdivide its outstanding shares of Common Stock into
         a larger number of shares of Common Stock, or

           2.1.3          combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock,

then (i) the number of Warrant Shares for which a Warrant is exercisable
immediately prior to the occurrence of any such event shall be adjusted to
equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which a Warrant is exercisable immediately
prior to the occurrence of such event would own or be entitled to receive after
the happening of such event and (ii) the Warrant Price immediately prior to the
occurrence of such event shall be adjusted to equal the product of the Warrant
Price multiplied by a fraction, the numerator of which shall be the number of
Warrant Shares for which a Warrant is exercisable immediately prior to the
adjustment and the denominator of which shall be the number of Warrant Shares
for which a Warrant is exercisable immediately after such adjustment.

         2.2     OTHER DIVIDENDS AND DISTRIBUTIONS.  If the Company shall make
or fix a record date for the holders of Common Stock entitled to receive a
dividend or other distribution payable in securities of the Company other than
shares of Common Stock, then lawful and adequate
   3

provision shall be made so that Holder shall be entitled to receive upon
exercise of the Warrants, for the aggregate Warrant Price in effect prior
thereto, in addition to the number of Warrant Shares immediately theretofore
issuable upon exercise of the Warrants, the kind and number of securities of
the Company which Holder would have owned and been entitled to receive had the
Warrants been exercised immediately prior to that date (pro rated in the case
of any partial exercise).

         2.3     RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.  If the Common
Stock is changed into the same or a different number of shares of any class or
classes of stock, whether by reclassification, exchange, substitution or
otherwise (other than a subdivision or combination of shares, stock dividend or
a reorganization, merger, consolidation or sale of assets, each as provided for
elsewhere in this Section 2) then the Holder of the Warrants shall be entitled
to receive upon exercise of the Warrants, in lieu of the Warrant Shares
immediately theretofore issuable upon exercise of the Warrants, for the
aggregate Warrant Price in effect prior thereto, the kind and amount of stock
and other securities and property receivable upon such reclassification,
exchange, substitution or other change, which Holder would have been entitled
to receive had the Warrants been exercised immediately prior to such
reclassification, exchange, substitution or change (pro rated in the case of
any partial exercise).

         2.4     REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALES OF ASSETS.
If any of the following transactions (each, a "Special Transaction") shall
become effective: (a) a capital reorganization (other than a dividend or other
distribution, subdivision, combination, reclassification, substitution or
exchange of shares provided for elsewhere in this Section 2), (b) a
consolidation or merger of the Company with and into another entity (where the
Company is not the surviving corporation or where there is a change in, or
distribution with respect to, the Common Stock), or (c) a sale or conveyance of
all or substantially all of the Company's assets, then, as a condition of the
Special Transaction, lawful and adequate provision shall be made so that Holder
shall thereafter have the right to purchase and receive upon exercise of the
Warrants, in lieu of the Warrant Shares immediately theretofore issuable upon
exercise of the Warrants, for the aggregate Warrant Price in effect immediately
prior to such consummation, such shares of stock, other securities, cash or
other assets ("Other Property") as may be issued or paid pursuant to the terms
of such Special Transaction to the holders of shares of Common Stock for which
such Warrants could have been exercised immediately prior to such Special
Transaction (pro rated in the case of any partial exercises).  In connection
with any Special Transaction, appropriate provision shall be made with respect
to the rights and interests of Holder to the end that the provisions of the
Warrants (including without limitation provisions for adjustment of the Warrant
Price and the number of Warrant Shares issuable upon the exercise of the
Warrants), shall thereafter be applicable, as nearly as may be practicable, to
any Other Property thereafter deliverable upon the exercise of the Warrants.
The Company shall not effect any Special Transaction unless prior to, or
simultaneously with, the closing, the successor entity (if other than the
Company), if any, resulting from such consolidation or merger or the entity
acquiring such assets shall assume by a written instrument executed and mailed
by certified mail or delivered to Holder at the address of Holder appearing on
the books of the Company, the obligation of the
   4

Company or such successor corporation to deliver to Holder such Other Property,
as in accordance with the foregoing provisions, which Holder shall have the
right to purchase.

         2.5     SALES BELOW CURRENT MARKET VALUE.

           2.5.1          Excluding shares, rights, options, warrants or
         convertible or exchangeable securities issued in any of the
         transactions described in Sections 2.1, 2.2, 2.3 or 2.4 above, in the
         event the Company shall (i) sell and issue shares of Common Stock at a
         price per share lower than the Current Market Price (defined below) or
         (ii) sell or issue rights, options, warrants or convertible or
         exchangeable securities containing the right to subscribe for or
         purchase shares of Common Stock and the price per share for which
         Common Stock is issuable upon the exercise, exchange or conversion of
         such rights, options, warrants or convertible or exchangeable
         securities shall be less than the Current Market Price, then the
         Warrant Price shall be reduced to a price determined by multiplying
         the Warrant Price by a fraction (i) the numerator of which shall equal
         the sum of (a) the number of shares of Common Stock outstanding at the
         close of business on the date immediately prior to the date of such
         issuance or sale plus (b) the number of shares of Common Stock that
         the maximum aggregate consideration received by the Company to effect
         such issuance or sale of Common Stock or the exercise, conversion or
         exchange of all of such rights, options, warrants or convertible or
         exchangeable securities into shares of Common Stock would purchase at
         the Warrant Price, and (ii) the denominator of which shall equal the
         number of shares of Common Stock outstanding at the close of business
         on the date of such issuance after giving effect to such issuance.
         For purposes of this Agreement, Current Market Price shall mean, in
         respect of any share of Common Stock on any date herein specified, (a)
         if there shall then be a public market for the Common Stock, the
         average of the daily market prices for 10 consecutive business days
         commencing 25 days before such date; the daily market price for each
         such business day being (i) the last sale price on such day on the
         Nasdaq National Market ("Nasdaq") or principal stock exchange on which
         such Common Stock is then listed, (ii) if no sale takes place on such
         day on any such exchange, the average of the last reported closing bid
         and asked prices on such day as officially quoted on Nasdaq or such
         principal exchange, (iii) if the Common Stock is not then listed or
         admitted to trading on Nasdaq or any stock exchange, the average of
         the last reported closing bid and asked prices on such day in the
         over-the-counter market, as furnished by the quotation systems upon
         which the Common Stock is then quoted, provided that such quotation
         systems are operated by the National Association of Securities Dealers
         ("NASD") or its affiliates or the National Quotation Bureau, Inc. or
         its affiliates, (iv) if none of such entities at the time is engaged
         in the business of reporting such prices, as furnished by any similar
         firm then engaged in such business, or (v) if there is no such firm,
         as furnished by any member of the NASD selected by the Company; or (b)
         at any time that there is no public market for the Common Stock, the
         fair market value per share of Common Stock on such date as determined
         in good faith by the Board of Directors of the Company.
   5

           2.5.2          For the purpose of making any adjustment required
         under this Section 2.5, the consideration received by the Company for
         any issue or sale of securities shall (a) if it consists of cash, be
         computed as the net amount of cash received by the Company after
         deduction of any expenses payable by the Company and any underwriting
         or similar commissions, compensation or concession in connection with
         such issue or sale, (b) if it consists of property other than cash, be
         computed at the fair value of that property as determined by the
         Company's Board of Directors in good faith, (c) if such shares of
         Common Stock or rights, options, warrants or convertible securities
         are issued or sold together with other stock or securities or other
         assets of the Company for a consideration which covers both, be
         computed as that portion of the consideration so received that may be
         reasonably determined by the Board of Directors of the Company in good
         faith to be allocated to such shares of Common Stock, or rights,
         options, warrants or convertible or exchangeable securities, and (d)
         if the issuance shall be of such rights, options, warrants or
         convertible or exchangeable securities to purchase Common Stock, be
         determined by dividing (x) the total amount receivable by the Company
         in consideration of the sale and issuance of such rights, options,
         warrants or convertible or exchangeable securities, plus the total
         consideration payable to the Company upon exercise, conversion or
         exchange thereof by (y) the total number of shares of Common Stock
         covered by such rights, options, warrants or convertible or
         exchangeable securities.

           2.5.3          Upon each adjustment of the Warrant Price per Warrant
         Share pursuant to Section 2.5.1, the Warrants shall thereupon evidence
         the right to purchase that number of shares of Common Stock
         (calculated to the nearest hundredth of a share) equal to (a) the
         product of (i) the number of shares of Common Stock for which a
         Warrant is exercisable immediately prior to such adjustment multiplied
         by (ii) the Warrant Price in effect immediately prior to such
         adjustment divided by (b) the Warrant Price in effect immediately
         after such adjustment.

           2.5.4          No further adjustments under this Section 2.5 shall
         be made upon the actual issuance of such Common Stock or upon exercise
         or conversion of such warrants, rights, options or convertible or
         exchangeable securities causing any adjustment under this Section 2.5.

         2.6     LIQUIDATION.  If the Company shall, at any time, prior to the
expiration of the Warrants, dissolve, liquidate or wind up its affairs, Holder
shall have the right, but not the obligation, to exercise the Warrants.  Upon
such exercise, Holder shall have the right to receive, in lieu of the shares of
Common Stock that Holder otherwise would have been entitled to receive upon
such exercise, the same kind and amount of assets as would have been issued,
distributed or paid to Holder upon any such dissolution, liquidation or winding
up with respect to such shares of Common Stock had Holder been the holder of
record of such shares of Common Stock receivable upon exercise of the Warrants
on the date for determining those entitled to receive any such distribution.
If any such dissolution, liquidation or winding up results in any cash
distribution in excess of the Warrant Price, Holder may, at Holder's option,
exercise the Warrants
   6

without making payment of the applicable Warrant Price and, in such case, the
Company shall, upon distribution to Holder, consider the applicable Warrant
Price per Warrant Share to have been paid in full, and in making settlement to
Holder shall deduct an amount equal to the applicable Warrant Price from the
amount payable to Holder.

         2.7     NOTICE.  Whenever the Warrants or the number of Warrant Shares
issuable hereunder is to be adjusted as provided herein or a dividend or
distribution (in cash, stock or otherwise and including, without limitation,
any distributions under Section 2.6) is to be declared by the Company, or a
definitive agreement with respect to a Special Transaction has been entered
into, the Company shall forthwith cause to be sent to the Holder at the last
address of the Holder shown on the books of the Company, by first-class mail,
postage prepaid, at least ten (10) days prior to the record date specified in
(a) below or at least twenty (20) days before the date specified in (b) below,
a notice stating in reasonable detail the relevant facts and any resulting
adjustments and the calculation thereof, if applicable, and stating (if
applicable):

           2.7.1          the date to be used to determine (a) which holders of
         Common Stock will be entitled to receive notice of such dividend,
         distribution, subdivision or combination (the "Record Date"), and (b)
         the date as of which such dividend distribution, subdivision or
         combination shall be made; or, if a record is not to be taken, the
         date as of which the holders of Common Stock of record to be entitled
         to such dividend, distribution, subdivision or combination are to be
         determined (provided, that in the event the Company institutes a
         policy of declaring cash dividends on a periodic basis, the Company
         need only provide the relevant information called for in this Section
         2.7.1 with respect to the first cash dividend payment to be made
         pursuant to such policy and thereafter provide only notice of any
         changes in the amount or the frequency of any subsequent dividend
         payments), or

           2.7.2          the date on which a Special Transaction is expected
         to become effective, and the date as of which it is expected that
         holders of Common Stock of record shall be entitled to exchange their
         shares of Common Stock for securities or other property deliverable
         upon consummation of the Special Transaction (the "Exchange Date").

         2.8     FRACTIONAL INTERESTS.  The Company shall not be required to
issue fractions of shares of Common Stock upon the exercise of a Warrant. If
any fraction of a share of Common Stock would be issuable upon the exercise of
a Warrant, the Company shall, upon such issuance, purchase such fraction for an
amount in cash equal to the current value of such fraction, computed on the
basis of the Current Market Price on the last business day prior to the date of
exercise.

         2.9     EFFECT OF ALTERNATE SECURITIES.  If at any time, as a result
of an adjustment made pursuant to this Section 2, Holder shall become entitled
to receive any securities of the Company other than shares of Common Stock,
then the number of such other securities receivable upon exercise of the
Warrants shall be subject to adjustment from time to time on terms as nearly
   7

equivalent as practicable to the provisions with respect to shares of Common
Stock contained in this Section 2.

         2.10    SUCCESSIVE APPLICATION.  The provisions of this Section 2
shall similarly apply from time to time to successive events covered by this
Section 2.

         2.11    WHEN ADJUSTMENTS ARE TO BE MADE.  The adjustments required by
this Section 2 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment to the number
of shares for which the Warrants are exercisable that would otherwise be
required may be postponed (except in the case of a subdivision or combination
of shares of the Common Stock, as provided for in Section 2.1) up to, but not
beyond, the date and time of exercise of any Warrants if such adjustment either
by itself or with other adjustments not previously made adds or subtracts less
than 1% to the number of shares of Common Stock for which the Warrants
initially issued pursuant to this Agreement are exercisable immediately prior
to the making of such adjustment.  Any adjustment representing a change of less
than such minimum amount (except as aforesaid) which is postponed shall be
carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 2 and not previously made, would result in
a minimum adjustment or on the date of exercise.  For the purpose of any
adjustment, any specified event shall be deemed to have occurred at the close
of business on the date of its occurrence.

         2.12    WHEN ADJUSTMENT NOT REQUIRED.  If the Company shall take a
record of the holders of its Common Stock for the purpose of entitling then to
receive a dividend or distribution or subscription or purchase rights and
shall, thereafter and before the distribution to stockholders thereof, legally
abandon its plan to pay or deliver such dividend, distribution, subscription or
purchase rights, then thereafter no adjustment shall be required by reason of
the taking of such record and any such adjustment previously made in respect
thereof shall be rescinded and annulled.

         2.13    SUPERSEDING ADJUSTMENT.  If, at any time after any adjustment
of the Warrant Price shall have been made pursuant to Section 2.6 as the result
of any issuance of warrants, options, rights or convertible or exchangeable
securities, and such warrants, options or rights, or the right of conversion or
exchange in such other convertible or exchangeable securities, shall expire,
and all or a portion of such warrants, options or rights, or the right of
conversion or exchange with respect to all or a portion of such other
convertible or exchangeable securities, as the case may be, shall not have been
exercised, then such previous adjustment shall be rescinded and annulled and,
if applicable, the Warrant Price shall be recalculated as if all such expired
and unexercised warrants, options, rights or convertible or exchangeable
securities had never been issued.

3        EXERCISE

         3.1     EXERCISE OF WARRANT.

           3.1.1          Holder may exercise a Warrant by (i) surrendering
         this Warrant Certificate, with the form of exercise notice attached
         hereto as Exhibit "A" duly executed by Holder, and (ii) making payment
         to the Company of the aggregate Warrant Price for the applicable
         Warrant Shares in cash, by certified check, bank check or wire
         transfer to an account designated by the Company.  Upon any partial
         exercise of the Warrants, the Company, at its expense, shall promptly
         issue to Holder for its surrendered Warrant Certificate a replacement
         Warrant Certificate identical in all respects to this Warrant
         Certificate, except that the number of Warrant Shares shall be reduced
         accordingly.

           3.1.2          Each person in whose name any Warrant Share
         certificate is issued upon exercise of any Warrants shall for all
         purposes be deemed to have become the holder of record of the Warrant
         Shares for which such Warrant was exercised, and such Warrant Share
         certificate shall be dated the date upon which the Warrant exercise
         notice was duly surrendered and payment of the purchase price was
         tendered to the Company.

         3.2     ISSUANCE OF WARRANT SHARES.  The Warrant Shares purchased
shall be issued to the holder exercising the Warrants as of the close of
business on the date on which all actions and payments required to be taken or
made by Holder, pursuant to Section 3.1, shall have been so taken or made.
Certificates for the Warrant Shares so purchased shall be delivered to Holder
within 10 days after the Warrants are surrendered.


4        RIGHTS OF HOLDER

         4.1     RIGHTS PRIOR TO EXERCISE.  Holder shall not, solely by virtue
of the Warrants and prior to the issuance of the Warrant Shares upon due
exercise thereof, be entitled to any rights of a shareholder in the Company.

         4.2     ISSUANCE OF WARRANT SHARES.  The Company shall not by any
action including, without limitation, amending its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of the
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 actions as may be necessary or
appropriate to protect the rights of Holder against impairment.  Without
limiting the generality of the foregoing, the Company will (a) take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of the Warrants and (b) use its best efforts to obtain all such
authorizations, exemptions or consents from any public
   9

regulatory body having jurisdiction thereof as may be necessary to enable the
company to perform its obligations with respect to the Warrants.

         Upon the request of Holder, the Company will at any time during the
period this Warrant is outstanding acknowledge in writing, in form satisfactory
to Holder, the continuing validity of the Warrants and the obligations of the
Company hereunder.


5        TRANSFERABILITY

         Holder may sell, assign, transfer or otherwise dispose of all or any
portion of the Warrants or the Warrant Shares acquired upon any exercise hereof
at any time and from time to time.  Upon the sale, assignment, transfer or
other disposition of all or any portion of the Warrants, Holder shall deliver
to Company a written notice of such in the form attached hereto as Exhibit B
duly executed by Holder which includes the identity and address of any
purchaser, assignor or transferee.


6        LEGEND ON WARRANT SHARES

         Certificates evidencing the Warrant Shares shall bear the following
legend until such time as the Warrant Shares are duly registered for resale:

           THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER
           THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER
           ANY APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED, 
           SOLD OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE 
           REGISTRATION UNDER THE ACT OR AN OPINION OF COUNSEL THAT SUCH 
           REGISTRATION IS NOT REQUIRED UNDER THE ACT AND THE RULES AND 
           REGULATIONS PROMULGATED THEREUNDER OR SUCH STATE SECURITIES LAWS.
   10

7        MISCELLANEOUS

         7.1     NOTICES.  All notices, requests, demands, claims, and other
communications hereunder shall be in writing and shall be delivered by
certified or registered mail (first class postage prepaid), or guaranteed
overnight delivery, to the Company at the address at which its principal
business office is located from time to time, and Holder at the address of
which it advises the Company in writing.

         7.2     PAYMENT OF TAXES.  The Company shall pay all expenses in
connection with, and all taxes and other governmental charges that may be
imposed with respect to, the issuance or delivery of Warrant Shares, unless
such tax or charge is imposed by law upon Holder, in which case such taxes or
charges shall be paid by Holder.  The Company shall not be required, however,
to pay any tax or other charge imposed in connection with any transfer involved
in the issue of any certificate for Warrant Shares in any name other than that
of Holder, and in such case the Company shall not be required to issue or
deliver any stock certificate until such tax or other charge has been paid or
it has been established to the satisfaction of the Company that no such tax or
other charge is due.

         7.3     AMENDMENT; WAIVER.  This Warrant Certificate may not be
modified, amended, supplemented, canceled or discharged, except by written
instrument executed by the Company and Holder.  No failure to exercise, and no
delay in exercising, any right, power or privilege under this Warrant
Certificate shall operate as a waiver, nor shall any single or partial exercise
of any right, power or privilege hereunder preclude the exercise of any other
right, power or privilege.  No waiver of any breach of any provision shall be
deemed to be a waiver of any preceding or succeeding breach of the same or any
other provision, nor shall any waiver be impled from any course of dealing
between the Company and Holder.  No extension of time for performance of any
obligations or other acts hereunder or under any other agreement shall be
deemed to be an extension of the time for performance of any other obligations
or any other acts.

         7.4     HEADINGS.  The headings contained in this Warrant Certificate
are for convenience of reference only and are not to be given any legal effect
and shall not affect the meaning or interpretation of this Warrant Certificate.

         7.5     GOVERNING LAW; INTERPRETATION.  This Warrant Certificate shall
be construed in accordance with and governed for all purposes by the laws of
the State of Delaware.

be duly executed and delivered as of the day and year first above written.
