                                    will submit a written notice (an "Advance
                                    Notice") to the Investor.  The Advance

                                    to the Investor every 7 trading days after

                                    Securities and Exchange Commission.  The
                                    date the Advance Notice is delivered to
                                    the Investor is called an "Advance Notice

                                    Advance Notice Date (the "Pricing Period").

Advance Date                        The Advance Date is the date on which the
                                    sale of the Common Stock and the payment

                                    day after the end of the relevant Pricing
                                    Period.  On each Advance Date, the Issuer

                                    common stock to the Investor or its
                                    designees via DWAC, against payment

                                    account by wire transfer of immediately
                                    available funds (provided that the shares
                                    of stock are received by the Investor no
                                    later than 1:00 pm EST) or next day
                                    available funds if the shares are received
                                    thereafter.

No Short Sales                      The Investor will not, and that it will
                                    cause its affiliates not to, engage in any
                                    short sales with respect to the Common
                                    Stock.

                                    effort to get the registration statement
                                    effective.  The Issuer shall continuously
                                    maintain the effectiveness of the
                                    registration statement for a period of 24
                                    months after the effective date.  The
                                    Issuer shall pay all offering expenses in
                                    connection with the registration.

                                    Issuer shall be responsible for all of its
                                    own fees and expenses incurred in
                                    connection with the documentation and

Commitment Fee                      Upon  closing,  the Issuer  shall  issue to
                                    the  Investor   restricted   shares  and/or
                                    warrants of the  Issuer's  common  stock in
                                    an  amount  equal  to 2% of the  Commitment
                                    Amount  based on a share  price  of  $0.001
                                    per  share.  The day of  closing is the day
                                    the  definitive  documents  are  signed  by
                                    both  parties.  These  shares and  warrants
                                    shall   have    "piggy-back"   and   demand
                                    registration rights.

                                    The  number  of  restricted  shares  issued
                                    will be  limited  to less  than 4.9% of the
                                    total  outstanding  shares of the Issuer at
                                    closing.    To   the   extent    that   the
                                    Commitment  Fee  exceeds  the  value of the
                                    restricted  shares,  the difference will be
                                    issued  in  the  form  of  warrants  with a
                                    strike  price  of  $0.001  per  share.  The
                                    number of warrants  will be  determined  by
                                    dividing  the  remaining   portion  of  the
                                    Commitment  Fee by the  difference  between
                                    closing  bid  price on the day prior to the
                                    Closing Date and $0.001 per share.

Commission                          Upon each Advance, the Investor shall
                                    receive directly from escrow cash
                                    compensation equal to five percent (5%) of
                                    the gross proceeds of such Advance.

Condition                           Issuer will agree to exchange
                                    approximately 800 million shares of common
                                    stock owned by Investor for convertible
                                    preferred stock that is convertible into
                                    800 million shares of common stock with
                                    registration rights.  The preferred stock
                                    will be subject to a cap whereby at no
                                    time will the Investor be able to convert
                                    into greater than 9.9% of the outstanding
                                    common stock of the Issuer.

                                    Issuer will terminate its status as a
                                    business development company under the
                                    Investment Company Act of 1940.

Confidentiality                     The existence of this term sheet and the
                                    individual terms and conditions are of a
                                    confidential nature and shall not be
                                    disclosed to anyone, except to the Issuer,
                                    the Investor and their respective legal
                                    advisors.

hereof, the Company may terminate this Agreement at any time by providing at
least thirty (30) days' prior written notice to the Executive. In the event that
the Company terminates this Agreement (a) other than in connection with a Change
of Control (as defined in Section 6 hereof), and (b) other than for Cause (as
defined in Section 5.3 hereof), the Company shall, notwithstanding such
termination, in consideration for all of the undertakings and covenants of the
Executive contained herein, continue to pay to the Executive the Base Salary and
the Regular Benefits for the remainder of the then-current Employment Term. In
addition, in the event the Company terminates this Agreement as described in the
immediately preceding sentence, any and all options granted to the Executive by
the Company shall become automatically and immediately vested and exercisable.
In no event however, shall the continuation of such payments during such
post-termination period be deemed to be employment hereunder for purposes of
calculating any bonus due to the Executive or for purposes of determining the
vesting or exercise period of any stock options granted hereunder, or otherwise.

            5.2 Termination by Executive. The Executive may terminate his
employment at any time for Good Reason and receive the payments and benefits
specified in Section 5.1 hereof in the same manner as if the Company had
terminated his employment without Cause. For purposes of this Agreement, "Good
Reason" will exist if any one or more of the following occur: failure by the
Company to honor any of its material obligations under this Agreement,
including, without limitation, its obligations under Section 4 hereof concerning
compensation, Section 10 hereof concerning indemnification, and Section 12.5
hereof concerning successor obligations.

            5.3 Termination for Cause. Notwithstanding the Employment Term, the
Company may terminate the Executive for Cause upon a resolution duly adopted by
the affirmative vote of not less than a majority of the entire membership of the
Board (excluding the Executive, if a director at such time). In the event that
the employment of the Executive is terminated by the Company for Cause, no
severance or other post-termination payment shall be due or payable by the
Company to the Executive (except solely such Base Salary or other payments as
may have been accrued but not yet paid prior to such termination). For purposes
hereof, "Cause" shall mean: (a) the conviction with respect to any felony or
misdemeanor involving theft, fraud, dishonesty or misrepresentation; (b) any
misappropriation, embezzlement or conversion of the Company's or any of its
subsidiary's or affiliate's property by the Executive; (c) willful misconduct by
the Executive in respect of the material duties or obligations of the Executive
under this Agreement; or (d) a material breach by the Executive of any of his
material obligations hereunder, after written notice thereof and a reasonable
opportunity of thirty (30) days to cure the same, provided that the same is not
caused by the physical disability including mental disease or defect of the
Executive, in which event Section 5.4 hereof shall apply.

            5.4 Death or Disability. In the event that the employment of the
Executive by the Company is terminated by reason of the death of the Executive
or by reason of medical or psychiatric disability which prevents the Executive
from satisfactorily performing a material portion of his duties for ninety (90)
consecutive calendar days or one hundred twenty (120) days in any three hundred
sixty-five (365) day period (a "Disability"), the Company shall, promptly upon
such termination, pay the Executive an amount equal to six (6) months of his
then-current Base Salary, in a single lump sum.

      6. Proprietary Rights.

            6.1 Non Competition. Except for (i) the Executive's position as an
officer of Fortress America Acquisition Corporation and its successors, (ii) the
Executive's ownership interest in Global Secure Corporation, and (iii) the
Executive's ownership interest and/or position in any future special purpose
acquisition corporations focused on homeland security, the Executive covenants
and agrees that for so long as he shall be employed by the Company and for a
period of two (2) years from the date of the termination of such employment for
any reason (the "Restricted Period") the Executive shall not directly or
indirectly, own, manage, control, operate invest in or become principal of
employee of, director of, or consultant to, any business, entity or venture
which is competitive with the business of the Company as conducted at such time;
provided, however, that it shall not be a violation of this Agreement for the
Executive to have beneficial ownership of less than five percent (5%) of the
outstanding amount of any class of securities of any enterprise (but without
otherwise participating in the activities of such enterprise) if such securities
are listed on a national securities exchange or quoted on an inter-dealer
quotation system.

            6.2 Confidentiality. The Executive recognizes and acknowledges that
certain confidential business and technical information used by the Employee in
connection with his duties hereunder that includes, without limitation, certain
confidential and proprietary information relating to the designing, development,
construction and marketing of computer hardware, is a valuable and unique asset
of the Company. Executive agrees that he shall at all times maintain the
confidentiality of the proprietary information and trade secrets of the Company,
and that he shall during the Restricted Period refrain from disclosing any such
information to the disadvantage of the Company.

                  6.2.1 During the Restricted Period the Executive shall not,
directly or indirectly: (a) solicit, in competition with the Company, any person
who is a customer of any business conducted by the Company, or (b) in any manner
whatsoever induce, or assist others to induce, any supplier of the Company to
terminate its association with such entity or do anything, directly or
indirectly, to interfere with the business relationship between the Company, and
any of their respective current or prospective suppliers.

                  6.2.2 During the Restricted Period the Executive shall not,
directly or indirectly, solicit or induce any employee of the Company to
terminate his or her employment for any purpose, including without limitation,
in order to enter into employment with any entity which competes with any
business conducted by the Company

            6.3 Ownership by Company. The Executive acknowledges and agrees that
any of his work product created, produced or conceived in connection with his
association with the Company shall be deemed work for hire and shall be deemed
owned exclusively by the Company. The Executive agrees to execute and deliver
all documents required by the Company to document or perfect the Company's
proprietary rights in and to the Executive's work product.

            6.4 Remedies. It is expressly understood and agreed that the
services to be rendered hereunder by the Executive are special, unique, and of
extraordinary character, and in the event of the breach by the Executive of any
of the terms and conditions of this Agreement on his part to be performed
hereunder, or in the event of the breach or threatened breach by the Executive
of the terms and provisions of this Section 6, then the Company shall be
entitled, if it so elects, to institute and prosecute any proceedings in any
court of competent jurisdiction, either in law or equity, for such relief as it
deems appropriate, including without limiting the generality of the foregoing,
any proceedings, to obtain damages for any breach of this Agreement, or to
enforce the specific performance thereof by the Executive.

      7. Market Standoff Agreement. The Executive hereby agrees that if so
requested by the Company or by any representative of any underwriters in
connection with any registration of the offering of any securities of the
Company under the Securities Act, the Executive shall not sell or otherwise
transfer any securities of the Company during the ninety (90) day period
following the effective date of a registration statement of the Company filed
under the Securities Act.

      8. Director's and Officer's Liability Insurance. To protect the Executive
from any liability, loss, claims, damages, or costs, including legal fees and
costs, prior to any public offering of any securities of the Company, the
Company may purchase and maintain director's and officer's liability insurance
(the "D&O Insurance") in an amount not less than Two Million Dollars
($2,000,000), or in such amount as is later agreed upon by the Executive and the
Company.

      9. Indemnification. As an employee, officer and director of the Company,
the Executive shall be indemnified against all liabilities, damages, fines,
costs and expenses by the Company in accordance with the indemnification
provisions of the Company's Certificate of Incorporation as in effect on the
date hereof, and otherwise to the fullest extent to which employees, officers
and directors of a corporation organized under the laws of the state of
incorporation of the Company may be indemnified pursuant to the laws of such
state, as the same may be amended from time-to-time (or any subsequent statute
of similar tenor and effect), subject to the terms and conditions of such
statute.

      10. Independent Representation. The Executive acknowledges that he has had
the opportunity to seek independent legal counsel and tax advice in connection
with the execution of this Agreement, and the Executive represents and warrants
to the Company (a) that he has sought such independent counsel and advice as he
has deemed appropriate in connection with the execution hereof and the
transactions contemplated hereby, and (b) that he has not relied on any
representation of the Company as to tax matters, or as to the consequences of
the execution hereof.

      10.1 Neutral Construction. No party may rely on any drafts of this
Agreement in any interpretation of the Agreement. Each party to this Agreement
has reviewed this Agreement and has participated in its drafting and,
accordingly, no party shall attempt to invoke the normal rule of construction to
the effect that ambiguities are to be resolved against the drafting party in any
interpretation of this Agreement.

            10.2 Attorneys' Fees. In the event that either party hereto
commences litigation against the other to enforce such party's rights hereunder,
the prevailing party shall be entitled to recover all costs, expenses and fees,
including reasonable attorneys' fees (including in-house counsel), paralegals,
fees, and legal assistants' fees through all appeals.

            11. General.

      11.1 No Brokers. Each of the parties to this Agreement represents and
warrants to the other that it has not utilized the services of any finder,
broker or agent. Each of the parties agrees to indemnify the other against any
and all liabilities to any person, firm or corporation claiming any fee or
commission of any kind on account of services rendered on behalf of such party
in connection with the transactions contemplated by this Agreement.

            11.2 Applicable Law. This document shall in all respects be governed
by the laws of the State of Delaware.

            11.3 Successor Obligations. The Company shall require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business and/or assets of the Company to
expressly assume by written agreement and to agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place.

            11.4 Survival. The parties hereto agree that the covenants contained
in Section 6 hereof shall survive any termination of employment by the Executive
and any termination of this Agreement.

            11.5 Assignability. All of the terms and provisions contained herein
shall inure to the benefit of and shall be binding upon the parties hereto and
their respective heirs, personal representatives, successors and assigns. The
obligations of the Executive however, may not be assigned, and the Executive may
not, without the Company's written consent, assign, transfer, convey, pledge,
encumber, hypothecate or otherwise dispose of this Agreement or any interest
therein. Any such attempted assignment or disposition shall be null and void and
without effect. Notwithstanding anything in this Section 11.5 to the contrary,
the Company and the Executive agree that this Agreement and all of the Company's
rights and obligations hereunder may be assigned or transferred by the Company
to and may be assumed by and become binding upon and may inure to the benefit of
any affiliate of or successor to the Company. The term "successor" shall mean,

corporation or other business entity which, by merger, consolidation, purchase
of the assets, or otherwise, acquires all or a material part of the assets of
the Company, including but not limited to HSCC. Any assignment by the Company of
its rights and obligations hereunder to any affiliate of or successor shall not
be considered a termination of employment for purposes of this Agreement.
