exact  legal  name are as set forth on the  first  page of this  Agreement.  The

authorized,  and  do not  conflict  with  Borrower's  formation  documents,  nor
constitute an event of default under any material agreement by which Borrower is
bound.  Borrower is not in default under any agreement to which,  or by which it
is bound, in which the default could  reasonably be expected to cause a Material
Adverse Change.

5.2   Collateral.

Liens. To Borrower's  knowledge,  the material Accounts are bona fide,  existing
obligations,  and the service or property has been performed or delivered to the

part of the  Intellectual  Property  set forth on  Schedule  5.2 has been judged
invalid  or  unenforceable,  in whole or in part,  and no claim has been made to

third party, except to the extent such claim could not reasonably be expected to
cause a Material Adverse Change.

5.3   Litigation.

      There are no actions or proceedings pending or, to the knowledge of any of
Borrower's  Responsible  Officers,  threatened  by or  against  Borrower  or any
Subsidiary in which a likely adverse  decision  could  reasonably be expected to
cause a Material Adverse Change.

9.3   Power of Attorney.

      Effective  only if an Event of  Default  occurs  and  while it  continues,
Borrower  irrevocably  appoints  Lender as its lawful  attorney  to: (i) endorse
Borrower's  name on any checks or other forms of payment or security;  (ii) sign
Borrower's  name on any  invoice  or bill of lading  for any  Account  or drafts
against  Account  Debtors,  (iii)  make,  settle,  and adjust  all claims  under
Borrower's insurance policies;  (iv) settle and adjust disputes and claims about
the  Accounts  directly  with account  debtors,  for amounts and on terms Lender
determines  reasonable;  and (v) transfer the Collateral into the name of Lender
or a third party as the Code permits.  Lender may exercise the power of attorney
to sign  Borrower's  name on any documents  necessary to perfect or continue the
perfection  of any security  interest  regardless of whether an Event of Default
has occurred.  Lender's  appointment as Borrower's  attorney in fact, and all of
Lender's rights and powers,  coupled with an interest, are irrevocable until all
Obligations  have been fully repaid and  performed  and Lender's  obligation  to
provide Credit Extensions terminates.

9.4   Accounts Collection.

      If an Event of Default occurs and continues,  Lender may notify any Person
owing Borrower money of Lender's  security  interest in the funds and verify the
amount of the  Account.  Borrower  must collect all payments in trust for Lender
and, if requested by Lender,  immediately  deliver the payments to Lender in the
form received from the account  debtor,  with proper  endorsements  for deposit.

and 8.3,  Lender shall have the right to withdraw funds from the SVB accounts in
an aggregate amount equal to the outstanding Obligations.

9.5   Lender Expenses.

      If  Borrower  fails to pay any amount or  furnish  any  required  proof of
payment to third  persons,  Lender may make all or part of the payment or obtain
insurance  policies  required  in Section  6.4,  and take any  action  under the
policies  Lender deems prudent.  Any amounts paid by Lender are Lender  Expenses
and  immediately due and payable,  bearing  interest at the then applicable rate
and secured by the Collateral.  No payments by Lender are deemed an agreement to
make similar payments in the future or Lender's waiver of any Event of Default.

9.6   Lender's Liability for Collateral.

      If Lender complies with reasonable  banking  practices and the Code, it is
not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage to
the Collateral;  (c) any diminution in the value of the  Collateral;  or (d) any
act or default of any carrier,  warehouseman,  bailee,  or other person, in each
case other than due to Lender's gross negligence or willful  misconduct.  Except

9.7   Remedies Cumulative.

      Lender's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative. Lender has all rights and remedies provided
under the Code, by law, or in equity.  Lender's  exercise of one right or remedy
is not an  election,  and  Lender's  waiver  of any  Event of  Default  is not a
continuing waiver. Lender's delay is not a waiver, election, or acquiescence. No
waiver is effective  unless signed by Lender and then is only  effective for the
specific instance and purpose for which it was given.

9.8   Demand Waiver.

      Borrower waives demand,  notice of default or dishonor,  notice of payment
and  nonpayment,  notice  of  any  default,  nonpayment  at  maturity,  release,
compromise,   settlement,   extension,   or  renewal  of  accounts,   documents,
instruments,  chattel paper,  and guarantees held by Lender on which Borrower is
liable.

9.9   Lockbox

      After the  occurrence  and during the  continuance of any Event of Default
under any of the Loan Documents, Lender shall have the right to require that all
items of  payment  of  Borrower  be  deposited  directly  into an  account to be
maintained  at  Lender  and from  which  only  Lender  shall  have the  right of
withdrawal.

      THIS THIRD AMENDMENT TO LOAN AND SECURITY AGREEMENT (this "Agreement") is
entered into as of December 22, 2003, by and among CROSSHILL GEORGETOWN CAPITAL,
L.P. ("Lender"), whose address is 1000 Wilson Boulevard, Suite 1850, Arlington,
Virginia 22209, Attn: Stephen X. Graham, SOLUTION TECHNOLOGY INTERNATIONAL, INC.
a corporation organized and in good standing in the State of Delaware
("Borrower"), whose address is 5210 Chairmans Court, Suite 3, Frederick,
Maryland 21703 and DAN JONSON, a resident of Garrett County, Maryland (the
"Principal").

                                    RECITALS.

      A. The Borrower and the Lender have entered into that certain Loan and
Security Agreement dated January 10, 2003, that certain First Amendment to Loan
and Security Agreement dated July 10, 2003 and that certain Second Amendment to
Loan and Security Agreement dated October 10, 2003 (as amended from time to
time, the " Loan Agreement"), pursuant to which the Lender has made a Committed
Revolving Line available to the Borrower in the maximum principal amount of
Seven Hundred Fifty Thousand Dollars ($750,000) (the "Revolving Line").

      B. The Revolving Loan is secured by the Collateral described in the Loan
Agreement and the Intellectual Property Collateral described in that certain
Intellectual Property Security Agreement dated January 10, 2003 by and between
Borrower and Lender.

      C. The Borrower is in default under of the Loan Agreement (as more fully
described in this Agreement) and has requested that the Lender waive such
defaults and extend the Revolving Maturity Date and the Lender has agreed on the
condition, among others, that this Agreement be executed and delivered by the
Borrower to the Lender.
<PAGE>

      D. Unless otherwise defined herein, capitalized terms used herein shall
have the respective meanings set forth in the Loan Agreement.

      NOW, THEREFORE, in consideration of the foregoing, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Borrower and the Lender do hereby agree as follows:

      1. Recitals. The parties hereto acknowledge and agree that the above
Recitals are true and correct in all material respects and that the same are
incorporated herein and made a part hereof by reference.

      2. Defined Terms. From and after the date hereof, the definition of
"Revolving Maturity Date" set forth in Section 13.1 of the Loan Agreement is
hereby amended and restated in its entirety as follows:

                  "Revolving Maturity Date" is March 31, 2004.

      3. Outstanding Obligations, Existing Defaults. Borrower agrees that as of
the date hereof, the unpaid principal balance of the Obligations is $750,000,
accrued and unpaid interest on the Obligations and unpaid fees as of December 1,
2003 are $_______. In addition, the Borrower agrees that if the Existing Default
(as hereinafter defined) were not waived, the Lender would be entitled pursuant
to Section 9.2 of the Loan Agreement, to charge interest at the default rate
through March 31, 2004 in an amount of $12,500.40 (the "Default Interest").
Borrower acknowledges and agrees that all such sums are due to the Lender
without offset or defense of any kind or nature. Borrower further acknowledges
and agrees that it is unable to repay the Obligations when due at maturity and
that such failure constitutes an Event of Default under the Loan Documents (such
Event of Default being called, the "Existing Default").

                                       2
<PAGE>

      4. Warrants. In consideration of the Lender's agreement to enter into this
Agreement, the Borrower shall execute and deliver to the Lender on the date
hereof, a Warrant to Purchase Stock in the form of Exhibit B attached hereto
(the " Replacement Warrant"). Borrower represents and warrants to the Lender
that the Replacement Warrant is duly authorized by Borrower and all necessary
shareholder and board consent and approvals have been obtained and further that
there are sufficient shares issued and available to honor its obligations under
the Replacement Warrant. The Replacement Warrant shall be and constitute, for
all purposes of the Loan Documents, a "Loan Document".

      5. Sale of Borrower. In consideration of the Lender's agreement to enter
into this Agreement, the Principal agrees that in the event the Obligations are
not repaid in full on or before the Revolving Maturity Date, at Lender's request
to use his best efforts to assist and cause Borrower and/or its assets to be
promptly sold on terms acceptable to Lender, at the expense of the Borrower;
provided however, in the event Lender requests Principal to travel to assist in
the sale of Borrower and/or its assets, Lender will advance any funds associated
with such travel to Principal.

      6. Waiver. Upon satisfaction of each of the conditions precedent set forth
in Section 8 of this Agreement, the Lender agrees to waive the Default Interest
and the Existing Default.

      7. Payment of Loan Fee. Borrower shall pay to Lender a fee in the amount
of Three Thousand Dollars ($3,000) (the "Loan Fee"), plus all out-of-pocket
expenses, including the Lender's attorneys' fees and expenses in the amount of
$2,400.00.

      10. Treatment of Events of Default and Waiver. If the Borrower or the
Principal shall fail to comply with the terms of any of their respective
representations, warranties, covenants or agreements contained herein or in the

Default and shall immediately entitle the Lender without further notice of any
kind or nature to exercise all rights and remedies provided in the Loan
Documents, as well as all other rights and remedies available to the Lender
under the law, including without limitation, the right to accrue interest from
the date of such default at the rate provided for in Section 9.2 of the Loan
Agreement.

      11. Counterparts. This Agreement may be executed in any number of
duplicate originals or counterparts, each of which duplicate original or
counterpart shall be deemed to be an original and all taken together shall
constitute one and the same instrument.

      12. Loan Documents; Governing Law; Etc. This Agreement is one of the Loan
Documents defined in the Loan Agreement and shall be governed and construed in
accordance with the laws of the Commonwealth of Virginia. The headings and
captions in this Agreement are for the convenience of the parties only and are

      13. No Defenses. Borrower agrees that, as of the date hereof, it has no

Borrower and the Principal each hereby waives and releases any claims to the
contrary.

      14. Waiver and Release of Claims. (a) Borrower and the Principal signing
below (each of the foregoing being a "Releasing Party") hereby releases,
acquits, and discharges Lender and Lender's employees, agents, representative,
consultants, attorneys, fiduciaries, servants, officers, directors, partners,
predecessors, successors and assigns, subsidiary corporations, parent
corporations, and related corporate divisions (all of the foregoing hereinafter
called the "Released Parties"), from all actions and causes of action,
judgments, executions, suits, debts, claims, demands, liabilities, obligations,
damages, and expenses of any and every character, known or unknown, direct
and/or indirect, at law or in equity, of whatsoever kind or nature, whether
heretofore or hereafter arising, for or because of any matter or things done,
omitted or suffered to be done by any of the Released Parties prior to and
including the date of execution hereof, and in any way directly or indirectly
arising out of or in any way connect to this Agreement and the Loan Documents,
including, but not limited to, claims relating to any settlement negotiation

the release set forth in this section, upon any representations, warranties, or
conditions by Lender or any other entity except as are specifically set forth in

admission by Lender of any liability to Borrower or any other entity.

      (d) Each Releasing Party warrants to Lender that it has not purported to

Releasing Party in any Released Matter to any other entity, and that the
foregoing constitutes a full and complete release of all Released Matters.

      15. Continuing Validity. Borrower and the Principal each understands and
agrees that in modifying the existing Obligations, Lender is relying upon
Borrower's representations, warranties, and agreements, as set forth in the Loan
Documents. Except as expressly modified pursuant to this Agreement, the terms of
