                           STRATUS SERVICES GROUP INC.

                        WARRANT TO PURCHASE COMMON STOCK

Warrant No.: 020 -PA                                     Number of Shares: 5,000

Date of Issuance: December 4, 2000

      Stratus Services Group Inc., , a Delaware corporation (the "Company"),
hereby certifies that, for Ten United States Dollars ($10.00) and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Hornblower & Weeks Financial, Inc., the registered holder hereof
or its permitted assigns, is entitled, subject to the terms set forth below, to
purchase from the Company upon surrender of this Warrant, at any time or times
on or after the date hereof, but not after 11:59 P.M. Eastern Time on the
Expiration Date (as defined herein) 5,000 fully paid and nonassessable shares of
Common Stock (as defined herein) of the Company (the "Warrant Shares") at the
purchase price per share provided in Section 1(b) below; provided, however, that
in no event shall the holder be entitled to exercise this Warrant for a number
of Warrant Shares in excess of that number of Warrant Shares which, upon giving
effect to such exercise, would cause the aggregate number of shares of Common
Stock beneficially owned by the holder and its affiliates to exceed 4.99% of the
outstanding shares of the Common Stock following such exercise, except within 60
days of the Expiration Date. For purposes of the foregoing proviso, the
aggregate number of shares of Common Stock beneficially owned by the holder and
its affiliates shall include the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which the determination of such proviso
is being made, but shall exclude shares of Common Stock which would be issuable
upon (i) exercise of the remaining, unexercised Warrants beneficially owned by
the holder and its affiliates and (ii) exercise or conversion of the unexercised
or unconverted portion of any other securities of the Company beneficially owned
by the holder and its affiliates (including, without limitation, any convertible
notes or preferred stock) subject to a limitation on conversion or exercise
analogous to the limitation contained herein. Except as set forth in the
preceding sentence, for purposes of this paragraph, beneficial ownership shall
be calculated in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended. For purposes of this Warrant, in determining the number of
outstanding shares of Common Stock a holder may rely on the number

<PAGE>

of outstanding shares of Common Stock as reflected in (1) the Company's most
recent Form 10-Q or Form 10-K, as the case may be, (2) a more recent public
announcement by the Company or (3) any other notice by the Company or its
transfer agent setting forth the number of shares of Common Stock outstanding.
Upon the written request of any holder, the Company shall promptly, but in no
event later than one (1) Business Day following the receipt of such notice,
confirm in writing to any such holder the number of shares of Common Stock then
outstanding. In any case, the number of outstanding shares of Common Stock shall
be determined after giving effect to the exercise of Warrants (as defined below)
by such holder and its affiliates since the date as of which such number of
outstanding shares of Common Stock was reported.

      Section 2. Exercise of Warrant.

            (a) Subject to the terms and conditions hereof, this Warrant may be
exercised by the holder hereof then registered on the books of the Company, pro
rata as hereinafter provided, at any time on any Business Day on or after the
opening of business on such Business Day, commencing with the April 29, 2001,
and prior to 11:59 P.M. Eastern Time on the Expiration Date, by (i) delivery of
a written notice, in the form of the subscription notice attached as Exhibit A
hereto (the "Exercise Notice"), of such holder's election to exercise this
Warrant, which notice shall specify the number of Warrant Shares to be
purchased, (ii) (A) payment to the Company of an amount equal to the Warrant
Exercise Price(s) applicable to the Warrant Shares being purchased, multiplied
by the number of Warrant Shares (at the applicable Warrant Exercise Price) as to
which this Warrant is being exercised (plus any applicable issue or transfer
taxes) (the "Aggregate Exercise Price") in cash or wire transfer of immediately
available funds or (B) notification to the Company that this Warrant is being
exercised pursuant to a Cashless Exercise (as defined in Section 2(f)) and (iii)
the surrender of this Warrant (or an indemnification undertaking reasonably
acceptable to the Company with respect to this Warrant in the case of its loss,
theft or destruction) to a common carrier for overnight delivery to the Company
as soon as practicable following such date. In the event of any exercise of the
rights represented by this Warrant in compliance with this Section 2(a), the
Company shall on the second Business Day following the date of receipt of the
Exercise Notice, the Aggregate Exercise Price (or notice of a Cashless Exercise)
and this Warrant (or an indemnification undertaking reasonably acceptable to the
Company with respect to this Warrant in the case of its loss, theft or
destruction) and, except for a Cashless Exercise, the receipt of the
representations of the holder specified in Section 6 hereof, if requested by the
Company (the "Exercise Delivery Documents"), and if the Common Stock is DTC
eligible credit such aggregate number of shares of Common Stock to which the
holder shall be entitled to the holder's or its designee's balance account with
The Depository Trust Company; provided, however, if the holder who submitted the
Exercise Notice requested physical delivery of any or all of the Warrant Shares,
or, if the Common Stock is not DTC eligible then the Company shall, on or before
the second Business Day following receipt of the Exercise Delivery Documents,
issue and surrender to a common carrier for overnight delivery to the address
specified in the Exercise Notice, a certificate, registered in the name of the
holder, for the number of shares of Common Stock to which the holder shall be
entitled pursuant to such request. Upon delivery of the Exercise Notice and
Aggregate Exercise Price referred to in clause (ii)(A) above or notification to
the Company of a Cashless Exercise referred to in Section 2(e), the holder of
this Warrant shall be deemed for all corporate purposes to have become the
holder of record of the Warrant Shares with respect to which this Warrant has
been exercised. In the case of a dispute as to the determination of the Warrant
Exercise Price, the Closing Bid Price or the arithmetic calculation of the
Warrant Shares, the Company shall promptly issue to the holder the number of
Warrant Shares that is not disputed and shall submit the disputed determinations
or arithmetic calculations to the holder via facsimile within one (1) Business
Day of receipt of the holder's Exercise Notice. If the holder and the Company
are unable to agree upon the determination of the Warrant Exercise Price or
arithmetic calculation of the Warrant Shares within one (1) day of such disputed
determination or arithmetic calculation being submitted to the holder, then the
Company shall immediately submit via facsimile (i) the disputed determination of
the Warrant Exercise Price or the Closing Bid Price to an independent, reputable
investment banking firm or (ii) the disputed arithmetic calculation of the
Warrant Shares to its independent, outside accountant The Company

                                       4
<PAGE>

shall cause the investment banking firm or the accountant, as the case may be,
to perform the determinations or calculations and notify the Company and the
holder of the results no later than forty-eight (48) hours from the time it
receives the disputed determinations or calculations. Such investment banking
firm's or accountant's determination or calculation, as the case may be, shall
be deemed conclusive absent manifest error.

            (b) Unless the rights represented by this Warrant shall have expired
or shall have been fully exercised, the Company shall, as soon as practicable
and in no event later than five (5) Business Days after any exercise and at its
own expense, issue a new Warrant identical in all respects to this Warrant
exercised except it shall represent rights to purchase the number of Warrant
Shares purchasable immediately prior to such exercise under this Warrant
exercised, less the number of Warrant Shares with respect to which such Warrant
is exercised.

            (c) No fractional Warrant Shares are to be issued upon any pro rata
exercise of this Warrant, but rather the number of Warrant Shares issued upon
such exercise of this Warrant shall be rounded up or down to the nearest whole
number.

            (d) If the Company or its Transfer Agent shall fail for any reason
or for no reason to issue to the holder within ten (10) Business Days of receipt
of the Exercise Delivery Documents, a certificate for the number of Warrant
Shares to which the holder is entitled or to credit the holder's balance account
with The Depository Trust Company for such number of Warrant Shares to which the
holder is entitled upon the holder's exercise of this Warrant, the Company
shall, in addition to any other remedies under this Warrant or the Placement
Agent Agreement or otherwise available to such holder, pay as additional damages
in cash to such holder on each day the issuance of such certificate for Warrant
Shares is not timely effected an amount equal to 0.5% of the product of (A) the
sum of the number of Warrant Shares not issued to the holder on a timely basis
and to which the holder is entitled, and (B) the Closing Bid Price of the Common
Stock for the trading day immediately preceding the last possible date which the
Company could have issued such Common Stock to the holder without violating this
Section 2.

            (e) If within fifteen (10) Business Days after the Company's receipt
of the Exercise Delivery Documents, the Company fails to deliver a new Warrant
to the holder for the number of Warrant Shares to which such holder is entitled
pursuant to Section 2(b) hereof, then, in addition to any other available
remedies under this Warrant or the Placement Agent Agreement, or otherwise
available to such holder, the Company shall pay as additional damages in cash to
such holder on each day after such tenth (10th) Business Day that such delivery
of such new Warrant is not timely effected in an amount equal to 0.25% of the
product of (A) the number of Warrant Shares represented by the portion of this
Warrant which is not being exercised and (B) the Closing Bid Price of the Common
Stock for the trading day immediately preceding the last possible date which the
Company could have issued such Warrant to the holder without violating this
Section 2.

            (f) If the Warrant Shares are not covered by an effective
registration statement for the resale of the Warrant Shares, the holder of this
Warrant may, at its election exercised in its sole discretion, exercise this
Warrant to the extent then exercisable, in lieu of making payment of the
Aggregate Exercise Price in cash, elect instead to receive upon such exercise
the "Net Number" of shares of Common Stock determined according to the following
formula (a "Cashless Exercise"):

                                       5
<PAGE>

            Net Number = (A x B) - (A x C)
                         -----------------
                                 B

            For purposes of the foregoing formula:

                  A=    the total number of Warrant Shares with respect to which
                        this Warrant is then being exercised.

                  B=    the Closing Bid Price of the Common Stock on the date of
                        exercise of the Warrant.

                  C=    the Warrant Exercise Price then in effect for the
                        applicable Warrant Shares at the time of such exercise.

      Section 3. Covenants as to Common Stock. The Company hereby covenants and
agrees as follows:

            (a) This Warrant is, and any Warrants issued in substitution for or
replacement of this Warrant will upon issuance be, duly authorized and validly
issued.

            (b) All Warrant Shares which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable and free from all taxes, liens and charges with respect
to the issue thereof.

            (c) During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved at least 100% of the number of shares of Common Stock needed to provide
for the exercise of the rights then represented by this Warrant and the par
value of said shares will at all times be less than or equal to the applicable
Warrant Exercise Price.

            (d) The Company will not, by amendment of 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 to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. The Company will take all such actions 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 this Warrant.

            (e) This Warrant will be binding upon any entity succeeding to the
Company by merger, consolidation or acquisition of all or substantially all of
the Company's assets.

                                       6

      Section 4. Taxes. The Company shall pay any and all taxes, except any
applicable withholding, which may be payable with respect to the issuance and
delivery of Warrant Shares upon exercise of this Warrant.

      Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise
specifically provided herein, no holder, as such, of this Warrant shall be
entitled to vote or receive dividends or be deemed the holder of shares of
capital stock of the Company for any purpose, nor shall anything contained in
this Warrant be construed to confer upon the holder hereof, as such, any of the
rights of a stockholder of the Company or any right to vote, give or withhold
consent to any corporate action (whether any reorganization, issue of stock,
reclassification of stock, consolidation, merger, conveyance or otherwise),
receive notice of meetings, receive dividends or subscription rights, or
otherwise, prior to the issuance to the holder of this Warrant of the Warrant
Shares which he or she is then entitled to receive upon the due exercise of this
Warrant. In addition, nothing contained in this Warrant shall be construed as
imposing any liabilities on such holder to purchase any securities (upon
exercise of this Warrant or otherwise) or as a stockholder of the Company,
whether such liabilities are asserted by the Company or by creditors of the
Company. Notwithstanding this Section 5, the Company will provide the holder of
this Warrant with copies of the same notices and other information given to the
stockholders of the Company generally, contemporaneously with the giving thereof
to the stockholders.

      Section 6. Representations of Holder. The holder of this Warrant, by the
acceptance hereof, represents that it is acquiring this Warrant and the Warrant
Shares for its own account for investment only and not with a view towards, or
for resale in connection with, the public sale or distribution of this Warrant
or the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided, however, that by making the representations herein,
the holder does not agree to hold this Warrant or any of the Warrant Shares for
any minimum or other specific term and reserves the right to dispose of this
Warrant and the Warrant Shares at any time in accordance with or pursuant to a
registration statement or an exemption under the Securities Act. The holder of
this Warrant further represents, by acceptance hereof, that, as of this date,
such holder is an "accredited investor" as such term is defined in Rule
501(a)(1) of Regulation D promulgated by the Securities and Exchange Commission
under the Securities Act (an "Accredited Investor"). Upon exercise of this
Warrant, other than pursuant to a Cashless Exercise, the holder shall, if
requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
holder's own account and not as a nominee for any other party, for investment,
and not with a view toward distribution or resale and that such holder is an
Accredited Investor. If such holder cannot make such representations because
they would be factually incorrect, it shall be a condition to such holder's
exercise of this Warrant, other than pursuant to a Cashless Exercise, that the
Company receive such other representations as the Company considers reasonably
necessary to assure the Company that the issuance of its securities upon
exercise of this Warrant shall not violate any United States or state securities
laws.

      Section 7. Ownership and Transfer.

                                       7
<PAGE>

            (a) The Company shall maintain at its principal executive offices
(or such other office or agency of the Company as it may designate by notice to
the holder hereof), a register for this Warrant, in which the Company shall
record the name and address of the person in whose name this Warrant has been
issued, as well as the name and address of each transferee. The Company may
treat the person in whose name any Warrant is registered on the register as the
owner and holder thereof for all purposes, notwithstanding any notice to the
contrary, but in all events recognizing any transfers made in accordance with
the terms of this Warrant.

            (b) The Company is obligated to register the Warrant Shares for
resale under the Securities Act pursuant to the Registration Rights Agreement
and the initial holder of this Warrant (and certain assignees thereof) is
entitled to the registration rights in respect of the Warrant Shares as set
forth in the Registration Rights Agreement.

      Section 8. Adjustment of Warrant Exercise Price and Number of Shares. The
Warrant Exercise Price and the number of shares of Common Stock issuable upon
exercise of this Warrant shall be adjusted from time to time as follows:

            (a) Adjustment of Warrant Exercise Price upon Subdivision or
Combination of Common Stock. If the Company at any time after the date of
issuance of this Warrant subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, any Warrant Exercise Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock obtainable upon exercise of this Warrant
will be proportionately increased. If the Company at any time after the date of
issuance of this Warrant combines (by combination, reverse stock split or
otherwise) one or more classes of its outstanding shares of Common Stock into a
smaller number of shares, any Warrant Exercise Price in effect immediately prior
to such combination will be proportionately increased and the number of Warrant
Shares issuable upon exercise of this Warrant will be proportionately decreased.
Any adjustment under this Section 8(d) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

            (b) Notices.

                  (i) Immediately upon any adjustment of the Warrant Exercise
Price, the Company will give written notice thereof to the holder of this
Warrant, setting forth in reasonable detail, and certifying, the calculation of
such adjustment.

                  (ii) The Company will give written notice to the holder of
this Warrant at least ten (10) days prior to the date on which the Company
closes its books or takes a record (A) with respect to any dividend or
distribution upon the Common Stock, (B) with respect to any pro rata
subscription offer to holders of Common Stock or (C) for determining rights to
vote with respect to any Organic Change (as defined below), dissolution or
liquidation, provided that such information shall be made known to the public
prior to or in conjunction with such notice being provided to such holder.

                                       8
<PAGE>

                  (iii) The Company will also give written notice to the holder
of this Warrant at least ten (10) days prior to the date on which any Organic
Change, dissolution or liquidation will take place, provided that such
information shall be made known to the public prior to or in conjunction with
such notice being provided to such holder.

      Section 9. Purchase Rights; Reorganization, Reclassification,
Consolidation, Merger or Sale.

            (a) In case of any (1) merger or consolidation of the Company with
or into another Person, or (2) sale by the Company of more than one-half of the
assets of the Company (on a book value basis) in one or a series of related
transactions, the holder of this Warrant shall have the right thereafter to (A)
exercise this Warrant for the shares of stock and other securities, cash and
property receivable upon or deemed to be held by holders of Common Stock
following such merger, consolidation or sale, and the holder shall be entitled
upon such event or series of related events to receive such amount of
securities, cash and property as the Common Stock for which this Warrant could
have been exercised immediately prior to such merger, consolidation or sales
would have been entitled to or (B) in the case of a merger or consolidation, (x)
require the surviving entity to issue common stock purchase warrants equal to
the number Warrant Shares to which this Warrant then permits, which newly
warrant shall be identical to this Warrant, and (y) simultaneously with the
issuance of such warrant, the holder of such warrant shall have the right to
exercise such warrant only into shares of stock and other securities, cash and
property receivable upon or deemed to be held by holders of Common Stock
following such merger or consolidation. In the case of clause (B), the exercise
price for such new warrant shall be based upon the amount of securities, cash
and property that each share of Common Stock would receive in such transaction
and the Exercise Price of this Warrant immediately prior to the effectiveness or
closing date for such transaction. The terms of any such merger, sale or
consolidation shall include such terms so as to continue to give the holder the
right to receive the securities, cash and property set forth in this Section
upon any conversion or redemption following such event. This provision shall
similarly apply to successive such events.

      Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant
is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt
of an indemnification undertaking (or, in the case of a mutilated Warrant, the
Warrant), issue a new Warrant of like denomination and tenor as this Warrant so
lost, stolen, mutilated or destroyed.

      Section 11. Notice. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Warrant must be in
writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of receipt is received by the sending party transmission is

      REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of November 20,
2000, by and among Stratus Services Group Inc., a Delaware corporation, with its

      WHEREAS:

A.    The Company has agreed to issue to May Davis common stock purchase
      warrants to purchase an aggregate seventy five thousand (75,000) shares of
      the Company's common stock, par value $0.01 per share (the "Common
      Stock"), and to issue to Hornblower common stock purchase warrants to
      purchase an aggregate fifty thousand (50,000) shares of the Company's
      Common Stock, each at a fixed exercise price for a term of five (5) years
      from the date of issuance of such warrants (individually, a "Warrant" and
      collectively, the "Warrants").

B.    To induce May Davis and Hornblower to act as a Placement Agent(s) for the
      Company, the Company has agreed to provide certain registration rights
      under the Securities Act of 1933, as amended, and the rules and
      regulations there under, or any similar successor statute (collectively,
      the "1933 Act"), and applicable state securities laws, with respect to the
      shares of Common Stock issuable upon exercise of the Warrants (the
      "Warrant Shares").

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Warrant
Holders hereby agree as follows:

      1. DEFINITIONS.

            As used in this Agreement, the following terms shall have the
following meanings:

            a. "Warrant Holder" means a Warrant Holder and any transferee or
assignee thereof to whom an Warrant Holder assigns its rights under this
Agreement and who agrees to become bound by the provisions of this Agreement in
accordance with Section 9.

            b. "Person" means a corporation, a limited liability company, an
association, a partnership, an organization, a business, an individual, a
governmental or political subdivision thereof or a governmental agency.

            c. "Register," "registered," and "registration" refer to a
registration effected by preparing and filing one or more Registration
Statements (as defined below) in compliance with the 1933 Act and pursuant to
Rule 415 under the 1933 Act or any successor rule providing

<PAGE>

for offering securities on a continuous or delayed basis ("Rule 415"), and the
declaration or ordering of effectiveness of such Registration Statement(s) by
the United States Securities and Exchange Commission (the "SEC").

            d. "Registrable Securities" means the shares of Common Stock
issuable to Warrant Holders upon conversion of the Warrants.

            e. "Registration Statement" means a registration statement under the
1933 Act which covers the Registrable Securities.

      2. REGISTRATION.

            a. Request for Registration. If the Company at any time proposes to
register any of its Common Stock under the 1933 Act for sale, whether for its
own account or for the account of other security holders or both (except with
respect to (x) registration statements on Form S-8 or Form S-4 or their then
equivalent forms, or another form not available for registering the Registrable
Securities for sale to the public, (y) a registration relating solely to
employee benefit plans, or (z) a registration relating solely to a Rule 145
transaction), it will each such time: (i) promptly give to the Warrant Holders
written notice thereof (which shall include a list of the jurisdictions in which
the Company intends to attempt to qualify such securities under the applicable
blue sky or other state securities laws); and (ii) include in such registration
(and any related qualification under blue sky laws or other compliance), and in
any underwriting involved therein, all the Registrable Securities specified in a
written request made by any such Warrant Holder within fifteen (15) days after
receipt of the written notice from the Company described in clause (i) above,
except that the amount of Registrable Securities included in such registration
on behalf of the Warrant Holders, if any, shall be subject to the provisions set
forth in Section 2c below. Such written request may specify all or a part of a
Warrant Holder's Registrable Securities.

            b. Underwritten Offerings. If the registration of which the Company
gives notice is for an underwritten offering of securities, the Company shall so
advise the Warrant Holders as a part of the written notice given pursuant to
Section 2a. In such event, the right of a Warrant Holder to a registration
pursuant to Section 2a above shall be conditioned upon the Warrant Holder's
participation in such underwriting. A Warrant Holder shall, if it proposes to
distribute Registrable Securities through such underwriting, (together with the
Company and other parties distributing securities through such underwriting)
enter into an underwriting agreement in customary form with the managing
underwriter(s) selected by the Company.

            c. Priority in Incidental Registrations. If (i) a registration
pursuant to this Section 2 involves an underwritten offering of the securities
so being registered, whether or not for sale for the account of the Company, and
(ii) the managing underwriter of such underwritten offering shall advise the
Company in writing that, in its opinion, the number or amount of securities
(including Registrable Securities) proposed to be sold in (or during the time
of) such offering would adversely affect the success of such offering, then the
Company shall include in such registration only such number or amount of
securities (including Registrable Securities) recommended by such managing
underwriter, selected in the following order or priority: (i) first, all of the
securities that the Company proposes to sell for its own account, if any, and
(ii) second,

                                       2
<PAGE>

the Registrable Securities requested to be included in such registration by the
Warrant Holders and Common Stock held by or issuable to securityholders of the
Company ("Other Holders") having the right to request inclusion of such Common
Stock in the registration (pro rata among the Warrant Holders and the Other
Holders based upon the number of shares requested to be included in the
registration).

      3. RELATED OBLIGATIONS.

            a. The Company shall keep a Registration Statement covering the
Warrant Shares effective during the term of the Warrant pursuant to Rule 415 at
all times until the date on which the Warrant Holder shall have sold all the
Registrable Securities covered by such Registration Statement, which
Registration Statement (including any amendments or supplements thereto and
prospectuses contained therein) shall not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading; provided, however, the Registration Statement
filed by the Company pursuant to the Registration Rights Agreement dated as of
December 1, 2000 among the Company and holders of the Company's 6% Convertible
Debentures due 2005 (the "Debenture Registration Rights Agreement"), the Company
shall have no obligation to keep such Registration Statement effective after
such time as the Registrable Securities may be sold under Rule 144(k) under the
1933 Act. The period during which the Company is required to keep a Registration
Statement effective pursuant to this Agreement is hereinafter referred to as the
"Registration Period".

            b. The Company shall prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to a Registration
Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the 1933 Act, as may be necessary to keep such Registration Statement
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act. In the case of amendments and
supplements to a Registration Statement which are required to be filed pursuant
to this Agreement (including pursuant to this Section 3(b)) by reason of the
Company's filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous
report under the Securities Exchange Act of 1934, as amended (the "1934 Act"),
the Company shall incorporate such report by reference into the Registration
Statement, if applicable, or shall file such amendments or supplements with the
SEC on the same day on which the 1934 Act report is filed which created the
requirement for the Company to amend or supplement the Registration Statement.

            c. The Company shall furnish to each Warrant Holder whose
Registrable Securities are included in any Registration Statement, without
charge, (i) at least one copy of such Registration Statement as declared
effective by the SEC and any amendment(s) thereto, including financial
statements and schedules, all documents incorporated therein by reference, all
exhibits and each preliminary prospectus, (ii) ten (10) copies of the final
prospectus included in such Registration Statement and all amendments and
supplements thereto (or such other number of copies as such Warrant Holder may
reasonably request) and (iii) such other documents as such Warrant Holder may
reasonably request from time to time in order to facilitate the disposition of
the Registrable Securities owned by such Warrant Holder.

                                       3
<PAGE>

            d. The Company shall use its best efforts to (i) register and
qualify the Registrable Securities covered by a Registration Statement under
such other securities or "blue sky" laws of such jurisdictions in the United
States as any Warrant Holder reasonably requests, (ii) prepare and file in those
jurisdictions, such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to (w) make any change to its certificate of incorporation or by-laws,
(x) qualify to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (y) subject itself to general
taxation in any such jurisdiction, or (z) file a general consent to service of
process in any such jurisdiction. The Company shall promptly notify each Warrant
Holder who holds Registrable Securities of the receipt by the Company of any
notification with respect to the suspension of the registration or qualification
of any of the Registrable Securities for sale under the securities or "blue sky"
laws of any jurisdiction in the United States or its receipt of actual notice of
the initiation or threat of any proceeding for such purpose.

            e. As promptly as practicable after becoming aware of such event or
development, the Company shall notify each Warrant Holder in writing of the
happening of any event as a result of which the prospectus included in a
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading (provided that in no event shall such
notice contain any material, nonpublic information), and promptly prepare a
supplement or amendment to such Registration Statement to correct such untrue
statement or omission, and deliver ten (10) copies of such supplement or
amendment to each Warrant Holder. The Company shall also promptly notify each
Warrant Holder in writing (i) when a prospectus or any prospectus supplement or
post-effective amendment has been filed, and when a Registration Statement or
any post-effective amendment has become effective (notification of such
effectiveness shall be delivered to each Warrant Holder by facsimile on the same
day of such effectiveness), (ii) of any request by the SEC for amendments or
supplements to a Registration Statement or related prospectus or related
information, and (iii) of the Company's reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate.

            f. The Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement,
or the suspension of the qualification of any of the Registrable Securities for
sale in any jurisdiction within the United States of America and, if such an
order or suspension is issued, to obtain the withdrawal of such order or
suspension at the earliest possible moment and to notify each Warrant Holder who
holds Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

            g. At the reasonable request of any Warrant Holder, the Company
shall furnish to such Warrant Holder, on the date of the effectiveness of the
Registration Statement and thereafter from time to time on such dates as an
Warrant Holder may reasonably request (i) a

                                       4
<PAGE>

letter, dated such date, from the Company's independent certified public
accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
and (ii) an opinion, dated as of such date, of counsel representing the Company
for purposes of such Registration Statement, in form, scope and substance as is
customarily given in an underwritten public offering, addressed to the Warrant
Holders.

            h. The Company shall make available for inspection by (i) any
Warrant Holder and (ii) one firm of accountants or other agents retained by the
Warrant Holders (collectively, the "Inspectors") all pertinent financial and
other records, and pertinent corporate documents and properties of the Company
(collectively, the "Records"), as shall be reasonably deemed necessary by each
Inspector, and cause the Company's officers, directors and employees to supply
all information which any Inspector may reasonably request; provided, however,
that each Inspector shall agree, and each Warrant Holder hereby agrees, to hold
in strict confidence and shall not make any disclosure (except to a Warrant
Holder) or use any Record or other information which the Company determines in
good faith to be confidential, and of which determination the Inspectors are so
notified, unless (a) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in any Registration Statement or is otherwise
required under the 1933 Act, (b) the release of such Records is ordered pursuant
to a final, non-appealable subpoena or order from a court or government body of
competent jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in violation of this
or any other agreement of which the Inspector and the Warrant Holder has
knowledge. Each Warrant Holder agrees that it shall, upon learning that
disclosure of such Records is sought in or by a court or governmental body of
competent jurisdiction or through other means, give prompt notice to the Company
and allow the Company, at its expense, to undertake appropriate action to
prevent disclosure of, or to obtain a protective order for, the Records deemed
confidential.

            i. The Company shall hold in confidence and not make any disclosure
of information concerning a Warrant Holder provided to the Company unless (i)
disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning a Warrant Holder is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Warrant Holder and allow such Warrant Holder, at the
Warrant Holder's expense, to undertake appropriate action to prevent disclosure
of, or to obtain a protective order for, such information.

            j. The Company shall use its best efforts either to cause all the
Registrable Securities covered by a Registration Statement (i) to be listed on
each securities exchange on which securities of the same class or series issued
by the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange or (ii) to secure
the inclusion for quotation on the National Association of Securities Dealers,
Inc. OTC

                                       5
<PAGE>

Bulletin Board for such Registrable Securities. The Company shall pay all fees
and expenses in connection with satisfying its obligation under this Section
3(j).

            k. The Company shall cooperate with the Warrant Holders who hold
Registrable Securities being offered and, to the extent applicable, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Warrant Holders may
reasonably request and registered in such names as the Warrant Holders may
request.

            l. The Company shall use its best efforts to cause the Registrable
Securities covered by the applicable Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to consummate the disposition of such Registrable Securities.

            m. The Company shall make generally available to its security
holders as soon as practical, but not later than 90 days after the close of the
period covered thereby, an earnings statement (in form complying with the
provisions of Rule 158 under the 1933 Act) covering a twelve-month period
beginning not later than the first day of the Company's fiscal quarter next
following the effective date of the Registration Statement.

            n. The Company shall otherwise use its best efforts to comply with
all applicable rules and regulations of the SEC in connection with any
registration hereunder.

            o. Within two (2) business days after a Registration Statement which
covers Registrable Securities is ordered effective by the SEC, the Company shall
deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Warrant
Holders whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A.

            p. The Company shall take all other reasonable actions necessary to
expedite and facilitate disposition by the Warrant Holders of Registrable
Securities pursuant to a Registration Statement.

      4. OBLIGATIONS OF THE WARRANT HOLDERS.

            Each Warrant Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(f) or
the first sentence of 3(e), such Warrant Holder will immediately discontinue
disposition of any Registrable Securities pursuant to any Registration
Statement(s) covering such Registrable Securities until such Warrant Holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 3(e) or receipt of notice that no supplement or amendment is required.
Notwithstanding anything to the contrary, the Company shall cause its transfer
agent to deliver unlegended certificates for shares of Common Stock to a
transferee of an Warrant Holder in accordance with the terms of the Placement
Agreement in connection with any sale of Registrable Securities with respect to
which a Warrant Holder has entered into a contract for sale prior to the Warrant
Holder's receipt of a notice from the Company of the happening of any event of
the kind

                                       6
<PAGE>

described in Section 3(f) or the first sentence of 3(e) and for which the
Warrant Holder has not yet settled.

      5. EXPENSES OF REGISTRATION.

            All expenses incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers, legal and accounting
fees, but excluding underwriting discounts and commissions and brokerage fees,
shall be paid by the Company.

      6. INDEMNIFICATION.

            With respect to Registrable Securities which are included in a
Registration Statement under this Agreement:

            a. To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Warrant Holder, the
directors, officers, partners, employees, agents, representatives of, and each
Person, if any, who controls any Warrant Holder within the meaning of the 1933
Act or the 1934 Act (each, an "Indemnified Person"), against any losses, claims,
damages, liabilities, judgments, fines, penalties, charges, costs, reasonable
attorneys' fees, amounts paid in settlement or expenses, joint or several
(collectively, "Claims") incurred in investigating, preparing or defending any
action, claim, suit, inquiry, proceeding, investigation or appeal taken from the
foregoing by or before any court or governmental, administrative or other
regulatory agency, body or the SEC, whether pending or threatened, whether or
not an indemnified party is or may be a party thereto ("Indemnified Damages"),
to which any of them may become subject insofar as such Claims (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon: (i) any untrue statement or alleged untrue statement of a
material fact in a Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the
offering under the securities or other "blue sky" laws of any jurisdiction in
which Registrable Securities are offered ("Blue Sky Filing"), or the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) any untrue
statement or alleged untrue statement of a material fact contained in any final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading; or (iii) any violation or alleged violation by the Company
of the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation there under relating to the
offer or sale of the Registrable Securities pursuant to a Registration Statement
(the matters in the foregoing clauses (i) through (iii) being, collectively,
"Violations"). The Company shall reimburse the Warrant Holders and each such
controlling person promptly as such expenses are incurred and are due and
payable, for any legal fees or disbursements or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (x) shall not apply to a Claim by an
Indemnified Person arising out of or based upon a Violation which occurs in
reliance upon and in conformity with

                                       7
<PAGE>

information furnished in writing to the Company by such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto; (y) shall not be
available to the extent such Claim is based on a failure of the Warrant Holders
to deliver or to cause to be delivered the prospectus made available by the
Company, if such prospectus was timely made available by the Company pursuant to
Section 3(e); and (z) shall not apply to amounts paid in settlement of any Claim
if such settlement is effected without the prior written consent of the Company,
which consent shall not be unreasonably withheld. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Warrant Holders pursuant to Section 9.

            b. In connection with a Registration Statement, each Warrant Holders
agrees to severally and not jointly indemnify, hold harmless and defend, to the
same extent and in the same manner as is set forth in Section 6(a), the Company,
each of its directors, each of its officers , employees, agents an
representatives of the Company each Person, if any, who controls the Company
within the meaning of the 1933 Act or the 1934 Act (each an "Indemnified
Party"), against any Claim or Indemnified Damages to which any of them may
become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such
Claim or Indemnified Damages arise out of or is based upon any Violation, in
each case to the extent, and only to the extent, that such Violation occurs in
reliance upon and in conformity with written information furnished to the
Company by such Warrant Holders expressly for use in connection with such
Registration Statement; and, subject to Section 6(d), such Warrant Holders will
reimburse any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such Claim; provided, however, that the
indemnity agreement contained in this Section 6(b) and the agreement with
respect to contribution contained in Section 7 shall not apply to amounts paid
in settlement of any Claim if such settlement is effected without the prior
written consent of such Warrant Holders, which consent shall not be unreasonably
withheld; provided, further, however, that the Warrant Holders shall be liable
under this Section 6(b) for only that amount of a Claim or Indemnified Damages
as does not exceed the net proceeds to such Warrant Holders as a result of the
sale of Registrable Securities pursuant to such Registration Statement. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer of
the Registrable Securities by the Warrant Holders pursuant to Section 9.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(b) with respect to any prospectus shall
not inure to the benefit of any Indemnified Party if the untrue statement or
omission of material fact contained in the prospectus was corrected and such new
prospectus was delivered to each Warrant Holders prior to such Warrant Holders'
use of the prospectus to which the Claim relates.

            c. Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an

                                       8
<PAGE>

Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. In the case of an
Indemnified Person, legal counsel referred to in the immediately preceding
sentence shall be selected by the Warrant Holders holding a majority in interest
of the Registrable Securities included in the Registration Statement to which
the Claim relates. The Indemnified Party or Indemnified Person shall cooperate
fully with the indemnifying party in connection with any negotiation or defense
of any such action or claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party
or Indemnified Person which relates to such action or claim. The indemnifying
party shall keep the Indemnified Party or Indemnified Person fully apprised at
all times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its prior written consent,
provided, however, that the indemnifying party shall not unreasonably withhold,
delay or condition its consent. No indemnifying party shall, without the prior
written consent of the Indemnified Party or Indemnified Person, consent to entry
of any judgment or enter into any settlement or other compromise which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability
in respect to such claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

            d. The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

            e. The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

      7. CONTRIBUTION.

            To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be

                                       9
<PAGE>

entitled to contribution from any seller of Registrable Securities who was not
guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

      8. REPORTS UNDER THE 1934 ACT.

            With a view to making available to the Warrant Holders the benefits
of Rule 144 promulgated under the 1933 Act or any similar rule or regulation of
the SEC that may at any time permit the Warrant Holders to sell securities of
the Company to the public without registration ("Rule 144") the Company agrees
to:

            a. make and keep public information available, as those terms are
understood and defined in Rule 144;

            b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Placement Agent Agreement) and the filing of such reports and other documents as
required by the applicable provisions of Rule 144; and

            c. furnish to each Warrant Holder so long as such Warrant Holder
owns Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested to
permit the Warrant Holders to sell such securities pursuant to Rule 144 without
registration.

      9. ASSIGNMENT OF REGISTRATION RIGHTS.

            The rights under this Agreement shall be automatically assignable by
the Warrant Holders to any transferee of all or any portion of Registrable
Securities if: (i) the Warrant Holder agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the
Company within a reasonable time after such assignment; (ii) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (a) the name and address of such transferee or assignee, and
(b) the securities with respect to which such registration rights are being
transferred or assigned; (iii) at or before the time the Company receives the
written notice contemplated by clause (ii) of this sentence the transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
contained herein; and (iv) such transfer shall have been made in accordance with
the applicable requirements of the Placement Agent Agreement.

      10. AMENDMENT OF REGISTRATION RIGHTS.

            Provisions of this Agreement may be amended and the observance
thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Warrant Holder who then hold at least two-thirds

                                       10
<PAGE>

accordance with this Section 10 shall be binding upon each Warrant Holders and
the Company. No such amendment shall be effective to the extent that it applies
to fewer than all of the holders of the Registrable Securities. No consideration
shall be offered or paid to any Person to amend or consent to a waiver or
modification of any provision of any of this Agreement unless the same
consideration also is offered to all of the parties to this Agreement.

whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or

Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

[TRANSFER AGENT]

Attn:_______________________________________

      Re: STRATUS SERVICES GROUP INC.

Ladies and Gentlemen:

      We are counsel to Stratus Services Group Inc., a Delaware corporation (the
"Company"), and have represented the Company in connection with that certain
Placement Agency Agreement (the "Placement Agent Agreement") entered into by and
among the Company and the Warrant Holders named therein (collectively, the
"Warrant Holders") pursuant to which the Company issued to the Warrant Holders
shares of its Common Stock, par value $0.01 per share (the "Common Stock") upon
conversion of the Warrants. Pursuant to the Placement Agent Agreement, the
Company also has entered into a Registration Rights Agreement with the Warrant
Holders (the "Registration Rights Agreement") pursuant to which the Company
agreed, among other things, to register the Registrable Securities (as defined
in the Registration Rights Agreement) under the Securities Act of 1933, as
amended (the "1933 Act"). In connection with the Company's obligations under the
Registration Rights Agreement, on ____________ ____, the Company filed a
Registration Statement on Form ________ (File No. 333-_____________) (the
"Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Warrant
Holders as a selling stockholder there under.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                           Very truly yours,

                                           [ISSUER'S COUNSEL]

                                        By:_____________________________________
