2THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS.
     THEY MAY NOT BE OFFERED OR TRANSFERRED BY SALE, ASSIGNMENT, PLEDGE OR
     OTHERWISE UNLESS A REGISTRATION STATEMENT FOR THESE SECURITIES UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND ANY APPLICABLE STATE SECURITIES
     LAWS IS IN EFFECT OR THE CORPORATION HAS RECEIVED AN OPINION OF COUNSEL,
     WHICH OPINION IS REASONABLY SATISFACTORY TO THE CORPORATION, TO THE EFFECT
     THAT SUCH REGISTRATION IS NOT REQUIRED.

                             CLEARSTORY SYSTEMS, INC

                         10% CONVERTIBLE PROMISSORY NOTE

$750,000                                                        June 15, 2005

                  FOR VALUE RECEIVED, CLEARSTORY SYSTEMS, INC, a Delaware
corporation (the "BORROWER"), hereby unconditionally promises to pay to SCP
PRIVATE EQUITY PARTNERS II, L.P., or its registered successor or assign (the
"HOLDER"), at Suite 300; 1200 Liberty Ridge Drive; Wayne, PA 19087 (or at such
other place as the Holder may specify to the Borrower in writing), the aggregate
principal amount of Seven Hundred Fifty Thousand Dollars ($750,000) (the "NOTE
AMOUNT") ON DEMAND. All payments hereunder shall be made in lawful money of the
United States of America and in immediately available funds. The obligations of
the Borrower under this Note shall be senior indebtedness of the Borrower, which
is senior to all its other indebtedness for borrowed money except (i) any other
notes in favor of Holder, and (ii) any obligations to Benefactor Funding Corp.,
a Colorado corporation ("BENEFACTOR"), under the Factoring and Security
Agreement, dated as of October 13, 2004 (the "FACTORING Agreement") between the
Borrower and Benefactor, with which it shall rank pari passu.

         1. INTEREST. The Borrower shall pay interest on the Note Amount from
and including the date hereof until payment in full at a fixed rate per annum
equal to ten percent (10%) compounded quarterly; PROVIDED, HOWEVER, that any
principal amount hereof not paid when due by demand or otherwise, and (to the
fullest extent permitted by applicable law) any overdue interest shall bear
interest at a fixed rate per annum equal to fifteen percent (15%) similarly
compounded (after as well as before judgment). Interest shall be calculated on
the basis of a 365-day year for the actual number of days elapsed, and shall be
payable ON DEMAND, and upon any acceleration hereunder.

         2. MANDATORY PREPAYMENT. Unless converted into shares or units of
Securities (as hereinafter defined), the Note Amount and all accrued interest
thereon, shall become due and be payable to the Holder in cash upon the
occurrence of any (i) merger or consolidation of the Borrower with or into any
other corporation or other entity or person (other than in which the holders of
capital stock of the Borrower immediately prior to such merger or consolidation
continue to hold at least ninety percent (90%) of the voting power of the
surviving or acquiring corporation), (ii) sale or pledge of all or substantially
all the assets of the Borrower, or (iii) transaction or series of transactions
in which more than fifty percent (50%) of the voting power of the capital stock
of the Borrower is disposed of to a single person or group of affiliated
persons.

<PAGE>

         3. OPTIONAL PREPAYMENT. This Note may be repaid at any time, with the
consent of the Holder, without premium or penalty, with any such repayment being
applied first to accrued but unpaid interest and thereafter to the Principal
Amount. The obligations of Borrower under this Note shall be absolute,
irrevocable and unconditional and shall remain in full force and effect until
the outstanding principal of and interest on this Note and all other amounts due
hereunder shall have been indefeasibly paid in full in immediately available
funds in accordance with the terms hereof, and this Note shall have been
canceled.

         4. COVENANTS OF THE BORROWER. Borrower hereby covenants and agrees not
to grant or permit to exist any mortgage, pledge, lien, security interest,
conditional or installment sale agreement, right of first refusal or similar
claims or encumbrances or charges of any kind against any of the assets of the
Borrower in favor of any party, except for liens and other encumbrances granted
to Benefactor under the Factoring Agreement, without the prior consent of the
Holder. In addition, to the extent required to comply with the conversion rights
of Holder under this Note, Borrower shall amend its Certificate of Incorporation
to authorize additional shares of Series C Convertible Preferred stock, and
sufficient numbers of shares of each class of Subsequent Round Securities as may
be issued by Borrower.

         5. OPTIONAL CONVERSION. Upon demand by the Holder, the Note Amount
hereof and the applicable interest accrued thereon, or any portion thereof, may
be converted at any time (i) into shares of the Borrower's Series C Convertible
Preferred Stock ("Series C Stock"), at a price of $1.9396 per share, or (ii)
upon consummation of an equity financing by the Borrower involving the issuance
of equity securities of the Borrower (the "Subsequent Round Securities") into
that number of such Subsequent Round Securities as are equal to the quotient
obtained by dividing (x) the sum of the Note Amount and interest accrued
thereon, or such portion thereof as Holder may wish to convert, by (y) the price
per share or unit of the Subsequent Round Securities. For the purposes hereof,
the Series C Stock and Subsequent Round Securities shall be collectively
referred to as the "Securities".

         Upon delivery by the Holder to the Borrower of a written notice of its
election to convert all or any portion of the Note Amount and accrued interest
pursuant to the preceding paragraph, without any further action on the part of
the Holder, the portion of this Note being converted, which may be all of this
Note, shall be cancelled and the Holder shall have no further rights with
respect to such cancelled portion of this Note other than the right to receive
shares of capital stock of the Borrower issuable upon conversion thereof. In the
event of a conversion of this Note in its entirety, the Borrower shall promptly
cause to be delivered to the Holder in exchange for this Note, which Holder
shall deliver to the Borrower, a certificate representing such equity securities
in accordance with this Section 5. In the event of a conversion of only a
portion of this Note, the Borrower shall also promptly deliver to the Holder a
new Note in the principal amount of the amount of this Note not converted. No
fractional shares or units of Securities will be issued upon conversion of this
Note. In lieu of any fractional share or unit to which the Holder would
otherwise be entitled upon a conversion hereunder, the Borrower will pay to the
Holder, in cash, the amount of the unconverted Note Amount and accrued interest
thereon that would otherwise be converted into such fractional share or unit.
Upon conversion of this Note, the Borrower will be forever released from all of
its obligations and liabilities under this Note with regard to that portion of
the Note Amount, and accrued interest thereon being converted.

demand tenor of this instrument, or the absolute right of Holder to make demand
for payment hereunder at any time in its sole discretion, each of the following

         material allegations of a petition filed against it in any proceeding
         under any such law;

              (v) there shall be filed against the Borrower an involuntary

         being hereinafter referred to as an "Involuntary Petition") and such
         Involuntary Petition shall not have been dismissed within thirty (30)
         days after it was filed;

              (vi) any judgment for the payment of money in excess of ten
         thousand dollars ($10,000) shall be rendered against the Borrower and
         the same shall remain undischarged for a period of fifteen (15)
         consecutive days, during which time execution is not effectively
         stayed;
