$40,000

                           Date of Issue: May 7, 2001

Digital Descriptor Systems, Inc. (a Delaware corporation) (hereinafter referred
to as the "Company" or "Borrower") is indebted and, for value received, herewith
promises to pay to:

                                  ROBERT GOWELL

or to his order, (together with any assignee, jointly or severally, the "Holder"
or "Lender") on the date which is six (6) months following the date of issue
(the "Original Due Date"), unless later extended by the Lender, in his sole
discretion, by Lender delivering written notice to Borrower within five (5)
business days prior to the Original Due Date of his desire to extend such
maturity, which notice shall contain the new maturity date which shall not be
more than 180 days following the Original Due Date (the "Due Date"), the sum of
FORTY THOUSAND DOLLARS ($40,000), or, if less, so much thereof as may be
outstanding from time to time (the "Principal Amount") and to pay interest on
the Principal Amount at the rate of Ten percent (10%) per annum as provided
herein. In furtherance thereof, and in consideration of the premises, covenants,
promises, representations and warranties hereinafter set forth the Borrower
hereby agrees as follows:

         1.   Interest. Interest on the Principal Amount outstanding from time
              to time shall accrue at the rate of 10% per annum, shall be based
              on a year of 360 days and shall be payable on the Original Due
              Date, or if Lender extends such date, the Due Date. Overdue
              principal and interest on the Note shall, to the extent permitted
              by applicable law, bear interest at the rate of 10% per annum. All
              payments of both principal and interest, shall be made at the
              address of the Holder hereof as it appears in the books and
              records of the Borrower, or at such other place as may be
              designated by the Holder hereof. Payments of both principal and
              interest are to be made in lawful money of the United States.

         2.   Maturity. If not converted by the Holder as hereinafter set forth,
              this Note shall mature on the Original Due Date or if Lender
              extends such Date, the Due Date at which time all then remaining
              unpaid principal, interest and any other charges then due
              hereunder shall be due and payable in full.

         3.   Prepayment. The principal amount hereof, together with interest
              thereon, may be prepaid, in whole or in part, prior to the
              scheduled maturity of this Note without premium or penalty. The
              Holder's conversion rights under paragraph 4 shall be extinguished
              if and to the extent that the Note is paid before the Holder gives
              its "Conversion Notice," as the term is defined in paragraph 4.

         4.   Conversion Right. The Holder of this Note shall have the right at
              Holder's sole option, at any time after the date which is thirty
              (30) days prior to the Original Due Date, or at any time during
              any extension of maturity

<PAGE>

              provided by Lender in accordance with the first paragraph of this
              Note, to convert all or, in multiples of $5,000, any part of this
              Note into such number of fully paid and nonassessable shares of
              common stock, $.001 par value, of the Company (the "Common Stock")
              as shall be provided herein. The Holder may exercise the
              conversion right by giving written notice (the "Conversion
              Notice") to Borrower of the exercise of such right and stating the
              name or names in which the stock certificate or stock certificates
              for the shares of Common Stock are to be issued and the address to
              which such certificates shall be delivered. The Conversion Notice
              shall be accompanied by a duly executed assignment of the portion
              of the Note that Holder desires to convert. The number of shares
              of Common Stock that shall be issuable upon conversion of the Note
              or any portion thereof shall equal the face amount of the Note or
              portion thereof divided by the Conversion Price as defined below
              and in effect on the date the Conversion Notice is given.
              Conversion shall be deemed to have been effected on the date the
              Conversion Notice is given (the "Conversion Date"). Within ten
              (10) business days after receipt of the Conversion Notice,
              Borrower shall issue and deliver by hand against a signed receipt
              therefor or by United States registered mail return receipt
              requested, to the address designated in the Conversion Notice, a
              stock certificate or stock certificates of Borrower representing
              the number of shares of Common Stock to which Holder is entitled
              and (if applicable) a check or cash in payment of all interest
              accrued and unpaid on the Note up to and including the Conversion
              Date unless Holder elects to apply such interest to the Conversion
              Price in accordance with Section 4(c) below. The conversion rights
              will be governed by the following provisions:

              (a)  Conversion Price: On the issue date hereof and until such
         time as an adjustment shall occur, the Conversion Price per share shall
         be an amount equal to 50% of the mean average price of the common stock
         of the Borrower for the ten (10) trading days prior to notice of
         conversion per share; provided, however, that the Conversion Price
         shall be subject to adjustment at the times, and in accordance with the
         provisions, as follows:

                   i) Adjustment of Issuance of Shares at less than the
                   Conversion Price: If and whenever any shares of Additional
                   Common Stock (as defined below) shall be issued by the
                   Company (the "Stock Issue Date") for a consideration per
                   share less than the Conversion Price, then in each such case
                   the Conversion Price shall be reduced to a new Conversion
                   Price in amount equal to the consideration per share received
                   by the Company for the shares of Additional Common Stock then
                   issued; and, in the case of shares issued without
                   consideration, the initial Conversion Price shall be reduced
                   in amount and the number of shares issued upon conversion
                   shall be increased in an amount so as to maintain for the
                   Holder the right to convert the Note into shares equal in
                   amount to the same percentage interest in the Common Stock of
                   the Company as existed for the Holder immediately preceding
                   the Stock Issue Date.

                   ii) Sale of Shares: In the event of the issuance of shares of
                   Additional Common Stock for a consideration part or all of
                   which shall be cash, the amount of the cash consideration


                                       2
<PAGE>

                   therefor shall be deemed to be the amount of the cash
                   received by the Company for such shares, after any
                   compensation or discount in the sale, underwriting or
                   purchase thereof by underwriters or dealers or others
                   performing similar services or for any expenses incurred in
                   connection therewith.

                   iii) Reclassification of Shares: In case of the
                   reclassification of securities into shares of Common Stock,
                   the shares of Common Stock issued in such reclassification
                   shall be deemed to have been issued for a consideration other
                   than cash. Shares of Additional Common Stock issued by way of
                   dividend or other distribution on any class of stock of the
                   Company shall be deemed to have been issued without
                   consideration.

                   iv) Split-up or Combination of Shares: In the event issued
                   and outstanding shares of Common Stock shall be subdivided or
                   split up into a greater number of shares of the Common Stock,
                   the Conversion Price shall be proportionately decreased, and
                   in the event issued and outstanding shares of Common Stock
                   shall be combined into a smaller number of shares of Common
                   Stock, the Conversion Price shall be proportionately
                   increased, such increase or decrease, as the case may be,
                   becoming effective at the time of record of the split-up or
                   combination, as the case may be.

                   v) Additional Common Stock: The term "Additional Common
                   Stock" herein shall mean all shares of Common Stock hereafter
                   issued by the Company (including Common Stock held in the
                   treasury of the Company), except Common Stock issued upon the
                   conversion of any portion of the Note.

              (b)  Adjustment for Mergers, Consolidations, Etc.:

                   i) In the event of distribution to all Common Stock holders
                   of any stock, indebtedness of the Company or assets
                   (excluding cash dividends or distributions from retained
                   earnings) or other rights to purchase securities or assets,
                   then, after such event, the Note will be convertible into the
                   kind and amount of securities, cash and other property which
                   the Holder of the Note would have been entitled to receive if
                   the Holder owned the Common Stock issuable upon conversion of
                   the Note immediately prior to the occurrence of such event.

                   ii) In the event of any capital reorganization,
                   reclassification of the stock of the Company (other than a
                   change in par value or as a result of a stock dividend,
                   subdivision, split up or combination of shares), or
                   consolidation or merger of the Company with or into another
                   person or entity (other than a consolidation or merger in
                   which the Company is the continuing corporation and which
                   does not result in any change in the Common Stock) or of the
                   sale, exchange, lease, transfer or other disposition of all
                   or substantially all of the properties and assets of the
                   Company as an entirety or the participation by the Company in
                   an exchange of shares as the corporation the stock of which
                   is to be acquired, this Note shall be convertible into the


                                       3
<PAGE>

                   kind and number of shares of stock or other securities or
                   property of the Company (or of the corporation resulting from
                   such consolidation or surviving such merger or to which such
                   properties and assets shall have been sold, exchanged,
                   leased, transferred or otherwise disposed, or which was the
                   corporation whose securities were exchanged for those of the
                   Company), to which the Holder of the Note would have been
                   entitled to receive if the Holder owned the Common Stock
                   issuable upon conversion of the Note immediately prior to the
                   occurrence of such event. The provisions of the foregoing
                   sentences of this Section 4(b)(ii) shall similarly apply to
                   successive reorganizations, reclassifications,
                   consolidations, mergers, sales, exchanges, leases, transfers
                   or other dispositions or other share exchanges.

                   iii) Notice of Adjustment: (A) In the event the Company shall
                   propose to take any action which shall result in an
                   adjustment in the Conversion Price, the Company shall give
                   notice to the Holder, which notice shall specify the record
                   date, if any, with respect to such action and the date on
                   which such action is to take place. Such notice shall be
                   given on or before the earlier of thirty (30) days before the
                   record date or the date which such action shall be taken.
                   Such notice shall also set forth all facts material to the
                   effect of such action on the Conversion Price and the number,
                   kind or class of shares or other securities or property which
                   shall be deliverable or purchasable upon the occurrence of
                   such action or deliverable upon conversion of this Note. (B)
                   Following completion of an event wherein the Conversion Price
                   shall be adjusted, the Company shall furnish to the Holder a
                   statement, signed by the Chief Executive Officer of the
                   Company, of the facts creating such adjustment and specifying
                   the resultant adjusted Conversion Price then in effect.

              (c) The Holder may, at his sole option, apply any accrued interest
         and/or principal outstanding on the Conversion Date towards the
         Conversion Price.

         5.   Reservation of Shares. Borrower warrants and agrees that it shall
              at all times reserve and keep available, free from preemptive
              rights, sufficient authorized and unissued, or of treasury, shares
              of Common Stock to effect conversion of this Note upon the terms
              and conditions contained herein.

         6.   Registration Rights. The Borrower has filed a Registration
              Statement on Form SB-2 under the United States Security Act of
              1933 and has included this Convertible Note and the underlying
              common stock thereunder from transfer by the Holder except if and
              unless the shares are duly registered for sale pursuant to the
              Securities Act of 1993, as amended, or the transfer is duly exempt
              from registration.

         7.   Taxes. The Borrower shall pay any documentary or other
              transactional taxes attributable to the issuance or delivery of
              this Note or the shares of Common Stock issued upon conversion by
              the Holder (excluding any federal, state or local income taxes and


                                       4
<PAGE>

              any franchise taxes or taxes imposed upon the Holder by the
              jurisdiction, or any political subdivision thereof, under which
              such Holder is organized or is qualified to do business).

         8.   Default.

              one or more of the following events (herein collectively called

                   notice thereof to Borrower from Lender, provided that such

              Holder of any one or more of such rights, powers or remedies shall
              not preclude the simultaneous or later exercise by the Holder of
              any or all such other rights, powers or remedies.

              (d)  Expenses: Upon the occurrence of a Default or an Event of
              Default, which occurrence is not cured within the applicable grace
              period, if any provided therefor, Borrower agrees to pay and shall
              pay all costs and expenses (including Lender's attorney's fees and
              expenses) reasonably incurred by Lender in connection with the
              preservation and enforcement of Lender's rights under the Note.

         9.   Failure to Act and Waiver. No failure or delay by the Holder to
              require the performance of any term or terms of this Note or nor
              to exercise any right, or any remedy shall constitute a waiver of
              any such term or of any right or of any default, nor shall such
              delay or failure preclude the Holder from exercising any such
              right, power or remedy at any later time or times. By accepting
              payment after the due date of any amount payable under this Note,
              the Holder shall not be deemed to waive the right either to
              require payment when due of all other amounts payable, or to later
              declare a default for failure to effect such payment of any such
              other amount. The failure of the Holder of this Note to give
              notice of any failure or breach of the Borrower under the Note
              shall not constitute a waiver of any right or remedy in respect of
              such continuing failure or breach or any subsequent failure or
              breach.
