                            REVOLVING PROMISSORY NOTE

$750,000                                                     Arlington, Virginia
                                                                January 10, 2003

      FOR VALUE RECEIVED,  the undersigned,  SOLUTION TECHNOLOGY  INTERNATIONAL,
INC.,  a  Delaware  corporation  ("Borrower"),  promises  to pay to the order of
CROSSHILL  GEORGETOWN  CAPITAL,  L.P.  ("Lender"),  at such  place as the holder
hereof may  designate,  in lawful  money of the United  States of  America,  the
aggregate unpaid principal amount of all advances ("Advances") made by Lender to
Borrower in  accordance  with the terms and  conditions of the Loan and Security
Agreement  between  Borrower  and Lender of even date  herewith (as amended from
time to time, the "Loan  Agreement"),  up to a maximum principal amount of Seven
Hundred Fifty Thousand Dollars ($750,000)  ("Principal Sum"), or so much thereof
as may be advanced or readvanced  and remains  unpaid.  Borrower  shall also pay
interest on the aggregate unpaid principal amount of such Advances, as follows:

      Commencing as of the date hereof and continuing until repayment in full of
all sums due hereunder,  the unpaid  principal amount of all Advances shall bear
interest of twelve percent (12%) per annum. All interest payable under the terms
of this Note shall be  calculated  on the basis of a 360-day year and the actual
number of days elapsed,  including the day any Advance is made and the day it is
repaid.

      The  unpaid  principal  amount of all  Advances,  together  with  interest
accrued and unpaid thereon, shall be due and payable as follows:

      (a)   Interest  only  on the  unpaid  principal  amount  shall  be due and
payable  monthly in arrears,  commencing on February 1, 2003,  and continuing on
the first day of each calendar month thereafter to maturity; and

      (b)   Unless  sooner paid,  the unpaid  principal  amount of all Advances,
together with interest  accrued and unpaid thereon,  shall be due and payable in
full on the Revolving Maturity Date.

      The fact that the  balance  hereunder  may be reduced to zero from time to
time pursuant to the Loan Agreement  will not affect the continuing  validity of
this  Note or the  Loan  Agreement,  and the  balance  may be  increased  to the
Principal Sum after any such reduction to zero.

      Borrower further agrees that, if any payment made by Borrower or any other
person  is  applied  to  this  Note  and is at any  time  annulled,  set  aside,
rescinded,  invalidated,  declared to be fraudulent or preferential or otherwise
required to be refunded or repaid,  or the  proceeds of any  property  hereafter
securing this Note is required to be returned by Lender to Borrower, its estate,
trustee,  receiver  or any other  party,  including,  without  limitation,  such
Borrower,  under  any  bankruptcy  law,  state or  federal  law,  common  law or
equitable  cause,  then, to the extent of such payment or repayment,  Borrower's


<PAGE>

liability  hereunder  (and any  lien,  security  interest  or  other  collateral
securing such liability) shall be and remain in full force and effect,  as fully
as if such  payment  had never been made,  or, if prior  thereto  any such lien,
security interest or other collateral  hereafter securing  Borrower's  liability
hereunder shall have been released or terminated by virtue of such  cancellation
or surrender,  this Note (and such lien,  security interest or other collateral)
shall be reinstated  in full force and effect,  and such prior  cancellation  or
surrender shall not diminish, release, discharge, impair or otherwise affect the
obligations  of Borrower in respect of the amount of such  payment (or any lien,
security interest or other collateral securing such obligation).

      This  Note  is the  "Revolving  Promissory  Note"  described  in the  Loan
Agreement,  to which  reference is hereby made for a more complete  statement of
the terms and conditions under which the loans and advances evidenced hereby are
made.  This Note is secured as provided in the Loan  Agreement.  All capitalized
terms used herein and not  otherwise  defined  shall have the meanings  given to
such terms in the Loan Agreement.

      Borrower irrevocably waives the right to direct the application of any and
all  payments  at any time  hereafter  received  by Lender  from or on behalf of
Borrower and Borrower  irrevocably  agrees that Lender shall have the continuing
exclusive  right to apply  any and all such  payments  against  the then due and
owing obligations of Borrower as Lender may deem advisable.  In the absence of a
specific  determination  by Lender with respect  thereto,  all payments shall be
applied in the following order: (a) then due and payable fees and expenses;  (b)
then due and payable interest payments and mandatory  prepayments;  and (c) then
due and payable principal payments and optional prepayments.

      Lender is hereby  authorized by Borrower to endorse on Lender's  books and
records  each  Advance  made by Lender  under  this Note and the  amount of each
payment or prepayment of principal of each such Advance  received by Lender;  it
being  understood,  however,  that failure to make any such  endorsement (or any
error in notation)  shall not affect the obligations of Borrower with respect to
Advances made hereunder, and payments of principal by Borrower shall be credited
to Borrower  notwithstanding  the  failure to make a notation  (or any errors in
notation) thereof on such books and records.

      The occurrence of any one or more of the following events shall constitute
an event of default (individually,  an "Event of Default" and collectively,  the
"Events of Default") under the terms of this Note:

      (a)   The  failure of  Borrower  to pay to  Lender,  within 10 days of the
applicable due date, any and all amounts payable by Borrower to Lender under the
terms of this Note; or

      (b)   The occurrence of an Event of Default (as defined therein) under the
terms and conditions of any of the other Loan Documents.


                                       2
<PAGE>

      Upon the occurrence of an Event of Default,  at the option of Lender,  all
amounts  payable  by  Borrower  to Lender  under  the  terms of this Note  shall
immediately  become due and  payable by  Borrower  to Lender  without  notice to
Borrower or any other person,  and Lender shall have all of the rights,  powers,
and  remedies  available  under the terms of this  Note,  any of the other  Loan
Documents and all applicable laws. Borrower and all endorsers,  guarantors,  and
other  parties who may now or in the future be primarily or  secondarily  liable
for the payment of the  indebtedness  evidenced  by this Note  hereby  severally
waive presentment,  protest and demand, notice of protest,  notice of demand and
of dishonor and  non-payment of this Note and expressly  agree that this Note or
any  payment  hereunder  may be  extended  from time to time  without in any way
affecting the liability of Borrower, guarantors and endorsers.

      Borrower promises to pay all reasonable costs and expense of collection of
this Note and to pay all reasonable attorneys' fees incurred in such collection,
whether  or not there is a suit or  action,  or in any suit or action to collect
this Note or in any appeal thereof. Time is of the essence as to all obligations
hereunder.

      This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

      Borrower  acknowledges  and agrees that this Note shall be governed by the
laws of the  Commonwealth of Virginia,  excluding  conflicts of laws principles,
even though for the convenience and at the request of Borrower, this Note may be
executed elsewhere.

      BORROWER  ACCEPTS  FOR  ITSELF  AND IN  CONNECTION  WITH  ITS  PROPERTIES,
UNCONDITIONALLY,  THE  EXCLUSIVE  JURISDICTION  OF ANY STATE OR FEDERAL COURT OF
COMPETENT  JURISDICTION IN THE COMMONWEALTH OF VIRGINIA IN ANY ACTION,  SUIT, OR
PROCEEDING  OF ANY KIND,  AGAINST  IT WHICH  ARISES  OUT OF OR BY REASON OF THIS
AGREEMENT.  BORROWER AND LENDER EACH HEREBY WAIVE THEIR  RESPECTIVE  RIGHTS TO A
JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION  BASED UPON OR ARISING  OUT OF ANY OF
THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS  CONTEMPLATED  THEREIN,  INCLUDING
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR
STATUTORY  CLAIMS.  EACH PARTY  RECOGNIZES AND AGREES THAT THE FOREGOING  WAIVER
CONSTITUTES  A MATERIAL  INDUCEMENT  FOR IT TO ENTER INTO THIS  AGREEMENT.  EACH
PARTY  REPRESENTS  AND WARRANTS  THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL
COUNSEL  AND THAT IT  KNOWINGLY  AND  VOLUNTARILY  WAIVES ITS JURY TRIAL  RIGHTS
FOLLOWING CONSULTATION WITH LEGAL COUNSEL.
