preferences and relative rights and qualifications, limitations or restrictions
thereof (in addition to those set forth in the Corporation's Articles of
Incorporation), shall be as stated below:


<PAGE>

The powers, preferences and rights granted to the Series A Convertible Preferred
Stock or the holders thereof are as follows:

1. DESIGNATION AND RANK. The series of Preferred Stock shall be designated the
"Series A Convertible Preferred Stock" (the "Series A") and shall consist of Two
Million Five Hundred Thousand (2,500,000) shares. The Series A and any other
series of Preferred Stock authorized by the Board of Directors of this
Corporation are hereinafter referred to as "Preferred Stock." The Series A shall
have a par value of $.01 per share and shall be senior to the Corporation's
Common Stock and all other shares of Preferred Stock that may be later
authorized.

2. VOTING RIGHTS. Except as otherwise required by law, the holders of Series A
and the holders of Common Stock shall be entitled to notice of any stockholders'
meeting and to vote as a single class upon any matter submitted to the
stockholders for a vote as follows: (i) the holders of each share of Series A
shall have twenty (20) votes on all matter in which the Common Stockholders and
Preferred Stockholders shall vote together as a group on the record date for the
vote, or, if no such record date is established, at the date such vote is taken
or any written consent of stockholders is solicited. The holders of Common Stock
shall have one vote per share of Common Stock held as of such date.

3. DIVIDEND RATE AND RIGHTS. Holders of the Series A shall be entitled to
receive Common Stock dividends or other distributions when, as, and if declared
by the directors of the Corporation, with the holders of the Common Stock on an
as converted basis.

4. CONVERSION INTO COMMON STOCK.

         RIGHT TO CONVERT. Each share of Series A shall be convertible, at the
option of the holder thereof and subject to notice requirements of the following
paragraph, at any time after the date of issuance of such share into eighteen
point six seven six three four seven (18.676347) shares of fully paid and
non-assessable shares of Common Stock. The Series A Conversion Ratio shall not
be subject to adjustment or effected by any split (forward or reverse) of the
Corporation's Common Stock.

         NOTICE OF CONVERSION. Each Series A stockholder who desires to convert
into the Corporation's Common Stock must provide a 65 day written notice to the
Corporation of intent to convert one or more shares of Series A into Common
Stock. The Corporation may, in its sole discretion, waive the written notice
requirement and allow the immediate exercise of the right to convert. It is the
purpose and intent of this provision to allow any Series A stockholder adequate
time to comply with any reporting obligations under applicable securities laws.


<PAGE>

         MECHANICS OF CONVERSION. No fractional shares of Common Stock shall be
issued upon conversion of Series A. In lieu of any fractional shares to which
the holder would otherwise be entitled, the Corporation shall round up to the
next whole share of Common Stock. The Corporation shall, as soon as practicable
thereafter, issue a certificate or certificates for the number of shares of
Common Stock to which the holder shall be entitled. The Corporation shall, as
soon as practicable after delivery of such certificates, or such agreement and
indemnification in the case of a lost, stolen or destroyed certificate, issue
and deliver to such holder of Series A, a certificate or certificates for the
number of shares of Common Stock to which such holder is entitled as aforesaid.
Such conversion shall be deemed to have been made immediately prior to the close
of business on the date of such surrender of the shares of Series A to be
converted.

         COMMON STOCK RESERVED. The Corporation shall reserve and keep available
out of its authorized but unissued Common Stock such number of shares of Common
Stock as shall from time to time be sufficient to effect conversion of the
Series A. It is expressly understood that at the time of this resolution that
the Corporation does not have sufficient authorized, but unissued Common Stock
in reserve and that an amendment to the Corporation's Articles will be required
before the Corporation can comply with this provision.

5. LIQUIDATION PREFERENCE. In the event of any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary (a
"Liquidation"), the assets of the Corporation available for distribution to its
stockholders shall be distributed as follows:

The holders of the Series A shall be entitled to receive, prior to the holders
of the other series of Preferred Stock and prior and in preference to any
distribution of the assets or surplus funds of the Corporation to the holders of
any other shares of stock of the corporation by reason of their ownership of
such stock, an amount equal to $.58 per share with respect to each share of
Series A, plus all declared but unpaid dividends with respect to such share.

If upon occurrence of a Liquidation the assets and funds thus distributed among
the holders of the Series A shall be insufficient to permit the payment to such
holders of the full preferential amount, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed among the
holders of the Series A ratably in proportion to the full amounts to which they
would otherwise be respectively entitled.

For purposes of this Section, and unless a majority of the holders of the Series
A affirmatively vote or agree by written consent to the contrary, a Liquidation
shall be deemed to include (i) the acquisition of the Corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation) and (ii) a sale
of all or substantially all of the assets of the Corporation, unless the
Corporation's stockholders of record as constituted immediately prior to such
acquisition or sale will, immediately after such acquisition or sale (by virtue
of securities issued as consideration for the Corporation's acquisition or sale
or otherwise) hold at least fifty percent (50%) of the voting power of the
surviving or acquiring entity.


<PAGE>

If any of the assets of the Corporation are to be distributed other than in cash
under this Section, then the board of directors of the Corporation shall
promptly engage independent competent appraisers to determine the value of the
assets to be distributed to the holders of Preferred Stock or Common Stock. The
Corporation shall, upon receipt of such appraiser's valuation, give prompt
written notice to each holder of shares of Preferred Stock or Common Stock of
the appraiser's valuation.

6. COVENANTS. In addition to any other rights provided by law, the Corporation
shall not, without first obtaining the affirmative vote or written consent of
the holders of a majority of the outstanding shares of Series A, do any of the
following:

take any action which would either alter, change or affect the rights,
preferences, privileges or restrictions of the Series A or increase the number
of shares of such series authorized hereby or designate any other series of
Preferred Stock; make fundamental changes to the business of the Corporation;

7. REISSUANCE. No share or shares of Series A acquired by the Corporation by
reason of conversion or otherwise shall be reissued as Series A, and all such
shares thereafter shall be returned to the status of undesignated and unissued
shares of Preferred Stock of the Corporation.

8. ELECTION OF DIRECTORS. The holders of Series A and Common Stock voting
together as a class shall be entitled to elect one (1) director comprising the
Corporation's Board of Directors (and to fill any vacancies with respect
thereto).

The undersigned being the President of the Corporation hereby declares under
penalty of perjury that the foregoing is a true and correct copy of the
Certificate of Designation of the Rights and Preferences of the Series A
Convertible Preferred Stock of Fleetclean Systems, Inc. duly adopted by all
necessary action by the Board of Directors of the Corporation on May 12, 2004.
