                          TERMS AND PURPOSE OF THE LOAN

      Section 2.1. Agreement To Lend. Subject to the terms and conditions of
this AGREEMENT and the other LOAN DOCUMENTS, the LENDER shall extend to the
BORROWER the LOAN.

      Section 2.2. Advances Of Loan Proceeds. Subject to the continued
satisfaction of all conditions precedent to the making of advances set forth in
Article 4 hereunder, and the continued absence of any default or any event,
circumstance, act or omission which with the giving of notice, the passage of
time, or both would constitute an EVENT OF DEFAULT, the LENDER shall advance to
the BORROWER by depositing into the COMMERCIAL ACCOUNT from time to time such
sums as the BORROWER may request; provided that the aggregate outstanding
principal balance of the LOAN at any one time shall never exceed the MAXIMUM
LOAN AMOUNT. The BORROWER shall not request any advance under the LOAN which
would cause the aggregate amount of advances made to or for the BORROWER and
outstanding under the LOAN DOCUMENTS to exceed the limitations as to the maximum
amount of advances as herein set forth. Any termination of the LOAN by the
LENDER in accordance with the terms of this AGREEMENT shall relieve the LENDER
of the LENDER's obligation to lend money or to make financial accommodations to
or for the BORROWER and the BORROWER's account pursuant to the LOAN DOCUMENTS,
and shall in no way release, terminate, discharge or excuse the BORROWER from
its absolute duty to pay or perform the OBLIGATIONS.

      Section 2.3. Interest And Repayment. All sums advanced under the LOAN
shall be evidenced by, and shall be repaid with interest in accordance with, the
provisions of the

<PAGE>

PROMISSORY NOTE, the terms and conditions of which are incorporated herein by
reference. The date and amounts of each advance made by the LENDER and each
payment made by the BORROWER shall be recorded by the LENDER on the books and
records of the LENDER, but any failure to record such dates or amounts shall not
relieve the BORROWER of its OBLIGATIONS under the LOAN DOCUMENTS. All repayments
shall be credited to the balance due from the BORROWER pursuant to the normal
and customary practices of the LENDER. Interest accrued under the LOAN shall be
computed on outstanding balances as reflected on the LENDER's books and records.

      Section 2.4. Term. All sums due under the LOAN shall be paid in full on or
before October 31, 2007. The BORROWER may borrow, repay and reborrow on or prior
to the termination of the LOAN, subject to the continued compliance by the
BORROWER with the terms and conditions of the LOAN DOCUMENTS.

      Section 2.5. Purpose. The proceeds of the LOAN shall be used by the
BORROWER solely and exclusively: (a) in payment or reimbursement of any costs
and expenses incurred by the BORROWER in connection with acquisitions by the
BORROWER, from time to time, during the term of the LOAN, of other businesses,
companies or operations (whether any such acquisition is consummated by means of
a merger, consolidation, acquisition of stock or assets or otherwise); and (b)
for such other purposes that may be approved by the EQUITY HOLDERS in writing
from time to time.

      Section 2.6. Requisition Procedure. Not less than two (2) banking days
prior to the date upon which an advance is to be made under the LOAN, the
BORROWER shall execute and deliver a fully completed requisition, in form and
substance acceptable to the LENDER, containing the specifics required therein
relating to the requested advance.

      Section 2.7. Payments Are Provisional. All payments made by the BORROWER
to the LENDER on any of the OBLIGATIONS shall be provisional and shall not be
considered final unless and until such payment is not subject to avoidance under
any provision of the United States Bankruptcy Code, as amended, including
Sections 547 and 550, or any state law governing insolvency or creditors'
rights. If any payment is avoided or set aside under any provision of the United
States Bankruptcy Code, including Sections 547 and 550, or any state law
governing insolvency or creditors' rights, the payment shall be considered not
to have been made for all purposes of this AGREEMENT and the LENDER shall adjust
its records to reflect the fact that the avoided payment was not made and has
not been credited against the OBLIGATIONS.

      Section 2.8. Commitment Fee. The BORROWER shall pay to the LENDER on or
before CLOSING a non-refundable and unconditional commitment fee equal the
product of twenty-five hundredths percent (0.25%) times the MAXIMUM LOAN AMOUNT,
which shall be the absolute property of the LENDER upon payment. The commitment
fee shall not be considered to be a payment of any of the LENDER'S EXPENSES
incurred in connection with the LOAN and shall be paid independent of the amount
of proceeds of the LOAN ultimately advanced to the BORROWER, even if that amount
is less than the stated MAXIMUM LOAN AMOUNT.

<PAGE>

      Section 2.9. Facility Fee. For each calendar quarter or portion thereof
during which the LOAN facility established hereunder is in existence and has not
been terminated, until the termination of the LOAN, the BORROWER shall pay to
the LENDER a facility fee equal to twenty-five hundredths percent (0.25%) per
annum on that sum obtained by subtracting the average daily disbursed principal
balance of the LOAN during such calendar quarter or portion thereof from the
stated face amount of principal set forth in the PROMISSORY NOTE. The facility
fee shall be payable quarterly, on the first day of each succeeding April, July,
October, and January, commencing with the first of such payments to be made on
January 1, 2005, or on the last day of a portion of a quarter. The facility fee
is not to be considered a fee being paid by the BORROWER to the LENDER as an
inducement to the LENDER to make advances, nor shall it be considered to modify
or limit the ability of the LENDER to terminate in accordance with the
provisions of this AGREEMENT the ability of the BORROWER to borrow under the
LOAN.

                                    ARTICLE 3
                              SECURITY FOR THE LOAN

      Section 3.1. Call Agreement. The repayment of the LOAN, the satisfaction
of the OBLIGATIONS, and the full, complete and absolute performance by the
BORROWER of each of the terms and conditions of the LOAN DOCUMENTS shall be
secured by the CALL AGREEMENT. Each EQUITY HOLDER shall execute and deliver, on
the date hereof, the CALL AGREEMENT in form and substance acceptable to the
LENDER. The amount of the respective "CALL CAP" (as that term is defined in the
CALL AGREEMENT) as to each respective EQUITY HOLDER shall be: (a) an amount
equal to sixty percent (60%) of the MAXIMUM LOAN AMOUNT as to LAZARD; and (b) an
amount equal to forty percent (40%) of the MAXIMUM LOAN AMOUNT as to STERLING.
The CALL AGREEMENT shall secure the payment and performance by the BORROWER of
the OBLIGATIONS; subject to the respective amounts of the CALL CAP.

      Section 3.2. Future Advances. The CALL AGREEMENT shall secure all current
and all future advances under the LOAN made by the LENDER to the BORROWER, or
for the account or benefit of the BORROWER, and the LENDER may advance or
readvance upon repayment by the BORROWER all or any portion of the sums loaned
to the BORROWER with respect to the LOAN and any such advance or readvance shall
be fully secured by the CALL AGREEMENT.

                                    ARTICLE 4
                              CONDITIONS PRECEDENT

(iii) accrued interest and other sums due as of the date of default;

            b. Impose the default rate of interest provided in the PROMISSORY
NOTE, with or without acceleration of the PROMISSORY NOTE;

            c. Foreclose or enforce all or any security interests, mortgage
interests, deed of trusts, liens, assignments, or pledges created by any LOAN
DOCUMENT;

            d. Confess judgment or file suit against the BORROWER on the
PROMISSORY NOTE or the EQUITY HOLDER on the CALL AGREEMENT;

            e. File suit against the BORROWER or the EQUITY HOLDER on this
AGREEMENT, the CALL AGREEMENT, or on any of the other LOAN DOCUMENTS;

<PAGE>

            f. Seek specific performance or injunctive relief to enforce
performance of the undertakings, duties, and agreements provided in the LOAN
DOCUMENTS, whether or not a remedy at law exists or is adequate; and

            g. Set-off any amounts in any account or represented by any
certificate with the LENDER in the name of the BORROWER or in which the BORROWER
has an interest.

      Section 7.2. Automatic Acceleration. If there occurs an event which would,
with the giving of notice, the passage of time, or both, constitute an EVENT OF
DEFAULT hereunder and if a voluntary or involuntary petition under the United
States Bankruptcy Code thereafter is filed by or against the BORROWER while such
event remains uncured, the LOAN shall be automatically accelerated and due and
payable and the default rates of interest provided for in the PROMISSORY NOTE
shall automatically apply as of the date of the first occurrence of the event
which would, with the giving of notice, the passage of time or both constitute
an EVENT OF DEFAULT, without any notice, demand or action of any type on the
part of the LENDER (including any action evidencing the acceleration or
imposition of the default rate of interest). The fact that the LENDER has, prior
to the filing of the voluntary or involuntary petition under the United States
Bankruptcy Code, acted in a manner which is inconsistent with the acceleration
and imposition of the default rate of interest provided for in the PROMISSORY
NOTE shall not constitute a waiver of this section or estop the LENDER from
asserting or enforcing the LENDER's rights hereunder.

      Section 7.3. Remedies Cumulative. The rights and remedies provided in this
AGREEMENT and in the other LOAN DOCUMENTS or otherwise under applicable LAWS
shall be cumulative and the exercise of any particular right or remedy shall not
preclude the exercise of any other rights or remedies in addition to, or as an
alternative of, such right or remedy.

      Section 7.4. Proof Of Sums Due On Loan. In any action or proceeding
brought by the LENDER to collect the sums owed on the LOAN, a certificate signed
by an officer of the LENDER setting forth the unpaid balances of principal, and
any accrued interest, default interest, legal fees, and late charges owed on the
LOAN shall be presumed correct and shall be admissible in evidence for the
purpose of establishing the truth of what it asserts. If the BORROWER wishes to
contest the accuracy of the figures set forth in any such certificate, the
BORROWER shall have the burden of proving that the certificate is inaccurate or
incorrect.

      Section 7.5. Obligations Are Unconditional. The payment and performance of
the OBLIGATIONS shall be the absolute and unconditional duty and obligation of
the BORROWER, and shall be independent of any defense or any rights of set-off,
recoupment or counterclaim which the BORROWER might otherwise have against the
LENDER, and the BORROWER shall pay absolutely during the terms of the LOAN the
payments of the principal and interest to be made on account of the LOAN and all
other payments required hereunder, free of any deductions and without abatement,
diminution or set-off other than those herein expressly provided. Until such
time as the OBLIGATIONS have been fully paid and performed, the BORROWER: (a)
shall not suspend or discontinue any payments provided for herein and in the
PROMISSORY NOTE; (b) shall perform and observe all of the BORROWER's other
covenants and agreements contained in the LOAN

<PAGE>

DOCUMENTS, including but not limited to making all payments required to be made
to the LENDER; and (c) shall not terminate or attempt to terminate the LOAN
DOCUMENTS for any cause.

                                    ARTICLE 8
                                  GENERAL TERMS

      Section 8.1. Lender Expenses. The PARTIES intend that all reasonable
LENDER EXPENSES shall be paid by the BORROWER, whether incurred prior to or
after CLOSING, subject to any limitations contained in this AGREEMENT.

      Section 8.2. Authorization To Obtain Financial Information. The BORROWER
hereby authorizes its accounting firm to provide the LENDER from time to time
with such information as may be requested by the LENDER, and hereby authorizes
the LENDER to contact directly its accounting firm in order to obtain such
information.

      Section 8.3. Incorporation; Inconsistent Provisions. The terms and
conditions of the LOAN DOCUMENTS are incorporated by reference and made a part
hereof, as if fully set forth herein. In the event of any inconsistency between
this AGREEMENT and any of the other LOAN DOCUMENTS, such inconsistency shall be
construed, interpreted, and resolved so as to benefit the LENDER, independent of
whether this AGREEMENT or another LOAN DOCUMENT controls, and the LENDER's
election of which interpretation or construction is for the LENDER's benefit
shall govern.

      Section 8.4. Waivers. The LENDER at any time or from time to time may
waive all or any rights under this AGREEMENT or any of the other LOAN DOCUMENTS,
but any waiver or indulgence by the LENDER at any time or from time to time
shall not constitute a future waiver of performance or exact performance by the
BORROWER.

      Section 8.5. Continuing Obligation Of Obligor. The terms, conditions, and
covenants set forth herein and on the LOAN DOCUMENTS shall survive CLOSING and
shall constitute a continuing obligation of the BORROWER during the course of
the transactions contemplated herein. The OBLIGATIONS of the BORROWER under this
AGREEMENT shall remain in effect so long as any OBLIGATION is outstanding,
unpaid or unsatisfied between the BORROWER and the LENDER.

      Section 8.6. Binding Obligation. This AGREEMENT shall be binding upon and
inure to the benefit of the PARTIES and their respective successors and assigns.

      Section 8.7. Final Agreement. This AGREEMENT and the LOAN DOCUMENTS
contain the final and entire agreement and understanding of the PARTIES, and any
terms and conditions not set forth in this AGREEMENT or the LOAN DOCUMENTS are
not a part of this AGREEMENT and the understanding of the PARTIES.

<PAGE>

      Section 8.8. Amendment. This AGREEMENT may be amended or altered only in
writing signed by the LENDER and such other PARTIES to be bound by the change or
alteration.

      Section 8.9. Time. Time is of the essence of this AGREEMENT.

      Section 8.10. Choice Of Law. The laws of the State of Maryland (excluding,
however, conflict of law principles) shall govern and be applied to determine
all issues relating to this AGREEMENT and the rights and obligations of the
PARTIES, including the validity, construction, interpretation, and
enforceability of this AGREEMENT and its various provisions and the consequences
and legal effect of all transactions and events which resulted in the execution
of this AGREEMENT or which occurred or were to occur as a direct or indirect
result of this AGREEMENT having been executed.

      Section 8.11. Consent To Jurisdiction; Agreement As To Venue. The BORROWER
and the LENDER: (a) irrevocably consent to the non-exclusive jurisdiction of the
courts of the State of Maryland and of the United States District Court for the
District of Maryland, if a basis for federal jurisdiction exists; (b) agree that
venue shall be proper in any circuit court of the State of Maryland or in the
United States District Court for the District of Maryland if a basis for federal
jurisdiction exists; and (c) waive any right to object to the maintenance of a
suit in any of the state or federal courts of the State of Maryland on the basis
of improper venue or of inconvenience of forum. Notwithstanding the terms of
this Section or any of the other LOAN DOCUMENTS to the contrary, the LENDER may
bring an action against the BORROWER in a court located outside of the State of
Maryland if the LENDER deems it necessary and appropriate to use such
non-Maryland court in order to protect, preserve, collect or otherwise take an
action with respect to COLLATERAL located outside of the State of Maryland.

      Section 8.12. Actions Against Lender Or Borrower. Any action brought by
the BORROWER or the LENDER against the other party hereto which is based,
directly or indirectly, on this AGREEMENT or any matter in or related to this
AGREEMENT, including but not limited to the making of the LOAN or the
administration or collection thereof, shall be brought only in the courts of the
State of Maryland. Neither party may file a counterclaim against the other party
in a suit brought by such party unless under the rules of procedure of the court
in which the action was brought or the counterclaim is mandatory, and not merely
permissive. Each party agrees that any forum other than the State of Maryland is
an inconvenient forum and that a suit brought by either party against the other
party in a court of any state other than the State of Maryland should be
forthwith dismissed or transferred to a court located in the State of Maryland
by that court.

      Section 8.13. Number, Gender, And Captions. As used herein, the singular
includes the plural and the plural includes the singular. The use of any gender
applies to all genders. The captions contained herein are for purposes of
convenience only and are not a part of this AGREEMENT.

      Section 8.14. Photocopies Sufficient. A carbon, photographic, photocopy or
other reproduction of a security agreement or financing statement shall be
sufficient as a financing statement.

<PAGE>

      Section 8.15. Notices. Any notice required or permitted by or in
connection with this AGREEMENT shall be in writing and shall be made by
facsimile (confirmed on the date the facsimile is sent by one of the other
methods of giving notice provided for in this Section) or by hand delivery, by
Federal Express, or other similar overnight delivery service, or by certified
mail, unrestricted delivery, return receipt requested, postage prepaid,
addressed to the LENDER or the BORROWER at the appropriate address set forth

of the facsimile or the receipt (or refusal to accept receipt) of hand delivery,
one (1) calendar day after delivery to Federal Express or similar overnight
delivery service, or three (3) calendar days after the date of mailing,
independent of the date of actual delivery or whether delivery is ever in fact
made, as the case may be, provided the giver of notice can establish the fact
that notice was given as provided herein. If notice is tendered pursuant to the
provisions of this Section and is refused by the intended recipient thereof, the
notice, nevertheless, shall be considered to have been given and shall be
effective as of the date herein provided.

                     Fax No.: (703) 749-1301

The failure of the LENDER to send the above courtesy copy shall not impair the
effectiveness of notice given to the BORROWER in the manner provided herein.

      Section 8.16. Participations. The LENDER reserves the absolute right to
assign all or any portion of its interests in any or all of the LOAN or the LOAN
DOCUMENTS or to participate with

<PAGE>

other lending institutions in the LOAN and the LOAN DOCUMENTS on such terms and
at such times as the LENDER may determine from time to time, all without any
consent thereto or notice thereof to the BORROWER. The BORROWER hereby grants to
each participating lending institution, to the full extent of the LOAN, the
right to set off deposit accounts maintained by the BORROWER with such
institution (provided that the BORROWER shall have received prior notice of the
assignment to such institution), and the BORROWER agrees to pay the LENDER
EXPENSES of any such participating lending institution which arise or are
incurred as a result of the occurrence of an EVENT OF DEFAULT.

      Section 8.17. Effective Date. This AGREEMENT shall be effective as of the
date first above written, independent of the date of execution or delivery
hereof.

      Section 10.18. Confidentiality. In handling any confidential information
of BORROWER or any of its SUBSIDIARIES, the LENDER and all employees and agents
of the LENDER shall exercise not less than the same degree of care that the
LENDER exercises with respect to its own proprietary information to maintain the
confidentiality of any non-public information thereby received or received
pursuant to this AGREEMENT or any of the other LOAN DOCUMENTS; except that
disclosure of such information may be made: (a) to prospective participants,
transferees or purchasers of any interest in the LOAN; (b) as required by LAW or
subpoena, judicial order or similar order; and (c) as the LENDER may reasonably
determine to be necessary in connection with the enforcement of any of its
remedies hereunder. Confidential information hereunder shall not include
information that either -- (i) is in the public domain, or becomes part of the
public domain after disclosure to the LENDER through no fault of the LENDER or
any of its employees or agents, or (ii) is disclosed to the LENDER by a third
party that is not under any obligation of confidentiality to the BORROWER.

      Section 10.19. Termination. This AGREEMENT shall terminate upon the
earlier to occur of: (a) October 31, 2007; and (b) such date as may be specified
in a written notice from the BORROWER to the LENDER electing to terminate this
AGREEMENT, provided that no OBLIGATIONS are outstanding as of such specified
date of termination. Upon the termination of this AGREEMENT, the LENDER will
promptly send the BORROWER: (i) for each jurisdiction in which a UCC financing
statement is on file to perfect the security interests granted to the LENDER
hereunder, a termination statement to the effect that the LENDER no longer
claims a security interest in such financing statement; and (ii) such other
documents necessary or appropriate to terminate the security interests granted
to the LENDER hereunder as may be reasonably requested by the BORROWER.

      Section 10.20. Waiver Of Trial By Jury. Each party to this AGREEMENT
agrees that any suit, action, or proceeding, whether claim or counterclaim,
brought or instituted by either party hereto or any successor or assign of any
party on or with respect to this AGREEMENT or any of the other LOAN DOCUMENTS or
which in any way relates, directly or indirectly, to the LOAN or any event,
transaction, or occurrence arising out of or in any way connected with the LOAN,
or the dealings of the PARTIES with respect thereto, shall be tried only by a
court and not by a jury. EACH PARTY HEREBY EXPRESSLY WAIVES ANY RIGHT TO A TRIAL
BY JURY IN ANY SUCH SUIT, ACTION, OR PROCEEDING. The BORROWER acknowledges and
agrees that this

<PAGE>

Section is a specific and material aspect of this AGREEMENT between the PARTIES
and that the LENDER would not extend the LOAN to the BORROWER if this waiver of
jury trial Section were not a part of this AGREEMENT.

                      [Signatures begin on the next page.]

                  collections in respect of such receivables) are with respect
                  to a customer (A) whose monthly or annual services or fees
                  were scheduled to commence on or after November 1, 2004 (in
                  which case such accounts, notes or receivables (or collections
                  in respect of such receivables) shall be Purchased Assets) or

                  of annual fees or services (in which case such accounts, notes
                  or receivables (or collections in respect of such receivables)

<PAGE>

                  attributable to the period greater than twelve (12) months
                  shall be Purchased Assets). For purposes of example:

                        (i) if, in December 2003, the Company collected or
                  invoiced $5,000 which related to the service period beginning
                  December 1, 2004 and ending on November 30, 2005, such amount
                  entirely would be a Purchased Asset because the payment or
                  invoice related to services which commenced after the Closing;

                        (ii) if, on October 1, 2004, the Company invoiced a
                  customer (x) $1,000 for the monthly service period beginning
                  on October 1, 2004 and ending on October 31, 2004, and (y)
                  $1,000 for the monthly service period beginning on November 1,
                  2004 and ending on November 31, 2004), such amount relating to
                  the first month of service would be an Excluded Asset because
                  the monthly services in question commenced on or prior to
                  October 31, 2004 and such amount relating to the second month
                  of service would be a Purchased Asset because the monthly
                  services in question commenced on or after November 1, 2004;

                        (iii) if, on November 1, 2004, the Company invoiced a
                  customer $5,000 for the service period beginning on November
                  1, 2004 and ending on October 31, 2005, such amount entirely
                  would be a Purchased Asset because the service period in
                  question commenced after October 31, 2004; and

                        (iv) if, on October 1, 2004, the Company invoiced a
                  customer $18,000 for the service period beginning on October
                  1, 2004 and ending on March 30, 2006, the amount would be
                  apportioned on the basis that $12,000 (or two-thirds) would be
                  an Excluded Asset (representing the first 12 months of
                  services) and $6,000 (or one third) would be a Purchased Asset
                  (representing the remaining 6 months of services); and

                        (v) if, on November 1, 2004, the Company invoiced a
                  customer $18,000 for the service period beginning on November
                  1, 2004 and ending on April 30, 2006, the entire amount would
                  be a Purchased Asset because the service in question commenced
                  after October 31, 2004.

            (4)   all Contracts other than the Assigned Contracts;

                                       11
<PAGE>

            (5)   all insurance policies;

            (6)   all cash and cash equivalents on hand and in banks;

            (7)   any Real Property or leases for Real Property other than the
                  Office Lease;

            (8)   any Purchased Assets sold or otherwise disposed of in the
                  ordinary course of business and not in violation of any
                  provisions of this Agreement during the period from June 30,
                  2004 until the Closing Date; and

            (9)   the Gnossos Software Inc. Political Action Committee (GNOPAC).

      Section 2.03. Assumed Liabilities. Upon the terms and subject to the
conditions of this Agreement, VGS agrees, effective at the time of the Closing,
to assume only the following liabilities (the "ASSUMED LIABILITIES"): (1) the

and the Company, as executed by the Company on November 21, 2003 (the "PHONE
LEASE"); (3) the Lease Agreement between CitiCapital/CitiCorp Vendor Finance,
Inc. and the Company dated October 29, 2003 (the "COPIER LEASE"); and (4) the
customer contracts listed on Schedule 2.01.

      Section 2.04. Excluded Liabilities. Notwithstanding any provision in this
Agreement or any other writing to the contrary, VGS is assuming only the Assumed
Liabilities and is not assuming any other liability or obligation of the Company
(or any predecessor of the Company or any prior owner of all or part of its
businesses and assets) of whatever nature, whether presently in existence or
arising hereafter. All such other liabilities and obligations shall be retained
by and remain obligations and liabilities of the Company (all such liabilities
and obligations not being assumed being herein referred to as the "EXCLUDED
LIABILITIES"). Without limiting the generality of the foregoing, the Company and
the Shareholder expressly acknowledge and agree that the Company shall retain,
and VGS shall not assume or otherwise be obligated to pay, perform, defend or
discharge:

            (1)   any liability or obligation of the Company and/or the
                  Shareholder for Taxes, whether measured by income or
                  otherwise;

            (2)   any liability or obligation for Taxes arising in connection
                  with any products or services sold, delivered or otherwise
                  provided by or on behalf of the Company prior to the Closing;

                                       12
<PAGE>

            (3)   any liability or obligation relating to employee benefits or
                  compensation arrangements existing on or prior to the Closing
                  Date, including any liability or obligation of the Company

            (6)   any liability or obligation to a third party with respect to
                  any Assumed Liability to the extent such liability or
                  obligation relates to or arises from any act or omission
                  taking place prior to the Closing Date;

            (7)   any liability or obligation of the Company to the Shareholder,
                  any Affiliate of the Company or the Shareholder, or any Person
                  claiming to have a right to acquire any capital stock or other
                  securities of the Company;

                  any customer under or in connection with any Assigned Contract
                  from and after December 31, 2006 (it being understood that VGS
                  is responsible for providing such products or services prior
                  to December 31, 2006 in accordance with the terms of such
                  Assigned Contract); or

            (11)  any liability or obligation under any Assigned Contract to the
                  extent that such liability or obligation exceeds the lesser of
                  (A) the amount of monies collected with respect to such
                  Assigned Contract by and for the account of VGS or the Parent
                  after the Closing and (B) the contract counterparty's actual,
                  direct damages under such Assigned Contract, unless such
                  liability arises from non-performance under the Assigned
                  Contract as a result of the negligent act or omission of the
                  Buyer (other than any failure to provide services or products
                  from and after December 31, 2006).

                                       13

The Company further agrees to use its commercially reasonable efforts to satisfy
and discharge promptly after the Closing all debts, obligations and liabilities
of the Company not specifically assumed by VGS hereunder.

      Section 2.05. Assignment of Contracts and Rights; Purchase Price
Adjustment.

            (a) Anything in this Agreement to the contrary notwithstanding, this
      Agreement shall not constitute an agreement to assign any Purchased Asset
      or any claim or right or any benefit arising thereunder or resulting
      therefrom if such assignment, without the consent of a third party
      thereto, would constitute a breach or other contravention of such
      Purchased Asset or in any way adversely affect the rights of the Buyer or
      the Company thereunder. The Company will use its reasonable best efforts
      (but without any payment of money by VGS or the Parent) to obtain the
      consent of the other parties to any such Purchased Asset or any claim or
      right or any benefit arising thereunder for the assignment thereof to VGS
      as VGS may request. If such consent is not obtained, or if an attempted
      assignment thereof would be ineffective or would adversely affect the
      rights of the Company thereunder so that VGS would not in fact receive all
      such rights, the Company and VGS will diligently cooperate in good faith
      in the thirty-five (35) days after the Closing to arrive at a mutually
      agreeable arrangement under which VGS would obtain the benefits and assume
      the obligations thereunder in accordance with this Agreement, including
      subcontracting, sub-licensing, or sub-leasing to VGS, or under which the
      Company would enforce for the benefit of VGS, with VGS assuming the
      Company's obligations, any and all rights of the Company against a third
      party thereto; provided that the foregoing procedures shall not apply to
      any Outsourcing Contracts. The Company will promptly pay to VGS when
      received all monies received by the Company under any Purchased Asset or
      any claim or right or any benefit arising thereunder, except to the extent
      the same represents an Excluded Asset.

            (b) At the Closing, the parties shall make the following downward
      adjustment in the consideration paid by VGS for the Purchased Assets with
      respect to the Contracts listed on Schedule 2.05(b): (1) with respect to
      any Outsourcing Contract listed on Schedule 2.05(b), an amount equal to
      220% of the product of (A) the most recent monthly fee paid by (or
      invoiced to) such customer and (B) 12; and (2) with respect any other
      Contract listed on Schedule 2.05(b), an amount equal to 220% of the most
      recent annual maintenance or service fee paid by such customer (or, if
      such customer is in the first year of service, the first annual
      maintenance or service fee which would be charged such customer under such
      Contract). The downward adjustment hereunder shall be offset at the
      Closing against the Cash Payment, and shall be subject to repayment to the
      Company in accordance with Section 2.05(f).

                                       14
<PAGE>

            (c) To the extent the benefits from any Purchased Asset and
      obligations thereunder have not been provided pursuant to Section 2.05(a)
      by alternate arrangements reasonably satisfactory to VGS, the parties
      shall make a downward adjustment in the consideration paid by VGS for the
      Purchased Assets as follows: (1) with respect to any Assigned Contract
      which is an Outsourcing Contract, an amount equal to 220% of the product
      of (A) the most recent monthly fee paid by (or invoiced to) such customer
      and (B) 12; (2) with respect to any Assigned Contract which is not an
      Outsourcing Contract, an amount equal to 220% of the most recent annual
      maintenance or service fee paid by such customer (or, if such customer is
      in the first year of service, the first annual maintenance or service fee
      which would be charged such customer under such Contract); and (3) with
      respect to any other Purchased Asset, an equitable adjustment to the
      Purchase Price. The downward adjustment hereunder shall be paid to VGS by
      the Company and/or the Shareholder on the date which is thirty-one (31)
      days after the Closing.

            (d) For purposes of illustration, (x) if the most recent annual
      maintenance fee paid by a customer under a Contract which is not an
      Outsourcing Contract were $4,000, then the Purchase Price would be reduced
      by $8,800 with respect to such Assigned Contract; and (y) if the most
      recent monthly fee payable by a customer under an Outsourcing Contract
      were $500, then the Purchase Price would be reduced by $13,200 (i.e., $500
      x 12 x 2.2) with respect to such Outsourcing Contract.

            (e) VGS may set off any Purchase Price adjustments hereunder against
      the Holdback Amount. To the extent that there remain unsatisfied any
      Purchase Price adjustments described above, the Parent and VGS shall have
      full recourse against the Shareholder and the Company (including their
      assets of whatsoever kind or nature) for the payment to VGS of any
      unsatisfied Purchase Price adjustment.

            (f) To the extent that VGS receives a purchase price adjustment with
      respect to a Contract listed on Schedule 2.05(b), and within thirty-five
      (35) days of the Closing the Company and the applicable customer
      thereunder enter into an amendment agreement in the form set forth on
      Schedule 2.05(f), then such Contract will be deemed an Assigned Contract
      for all purposes under this Agreement and VGS shall pay the Company the
      amount of any adjustment made with respect to such Contract pursuant to
      Section 2.05.

            (g) If, prior to the first anniversary of the Closing, VGS or the
      Parent enters into a contract for services similar to those provided to
      the same customer pursuant to a Contract for which VGS has received a
      purchase price adjustment pursuant to Sections 2.05(b) or 2.05(c), then
      VGS promptly shall credit the applicable purchase price adjustment back to
      the Holdback Amount (if such purchase price adjustment were set off
      against the Holdback Amount) or pay the purchase price adjustment to the
      Company (if such adjustment had

                                       15
<PAGE>

      not been set off against the Holdback Amount and instead had been paid
      separately to VGS by the Company or the Shareholder).

         Section 2.06. Purchase Price.

            (a) The purchase price for the Purchased Assets (the "PURCHASE
      PRICE") is (x) Two Million Nine Hundred Thousand Dollars ($2,900,000) in
      cash, less any purchase price adjustment pursuant to Section 2.05 (the
      "CASH PAYMENT"), of which $20,000 was paid to the Company prior to the
      Closing as a deposit and $185,000 was delivered to an escrow account and

      Section 3.24. Investment Representations of the Company and the
Shareholder. In connection with its acquisition of capital stock of the Parent,
the Company and the Shareholder hereby jointly and severally represent and
warrant to VGS and the Parent as follows:

         (a) In evaluating the suitability of an investment in Parent, the
   Company and the Shareholder have not relied upon any representations or other
   information (whether written or oral) from VGS or the Parent except as
   expressly set forth herein.

         (b) THE COMPANY AND THE SHAREHOLDER ARE AWARE THAT AN INVESTMENT IN THE
   PARENT INVOLVES A HIGH DEGREE OF RISK.

                                       28
<PAGE>

         (c) The Company and the Shareholder recognize that any information
   furnished by VGS or the Parent does not constitute investment, accounting,
   tax or legal advice. Moreover, the Company and the Shareholder are not
   relying upon VGS or the Parent with respect to the Company's and the
   Shareholder's tax and other economic circumstances in connection with its
   investment in VGS or the Parent. In regard to the tax and other economic
   considerations related to such investment, the Company and the Shareholder
   have relied solely on the advice of, or have consulted with, only their own
   professional advisors.

         (d) The Company and the Shareholder are aware that the Shares are being
   offered and sold by means of an exemption under the Securities Act of 1933,
   as amended (the "ACT"), as well as exemptions under certain state securities
   laws for nonpublic offerings, and that it makes the representations,
   declarations and warranties as contained in this Section 3.24 with the intent
   that the same shall be relied upon in determining their suitability as a
   purchaser of the Shares.

         (e) Each of the Company and the Shareholder is an "ACCREDITED INVESTOR"
   as defined in Rule 501 of Regulation D and has such knowledge and experience
   in financial and business matters that it is capable of evaluating the merits
   and risks of an investment in VGS or the Parent and of making an informed and
   intelligent investment decision.

         (f) The Company and the Shareholder are aware that they cannot sell or
   otherwise transfer the Shares without registration under applicable federal
   or state securities laws or without an exemption therefrom, and are aware
   that they will be required to bear the financial risks of their purchase for
   an indefinite period of time because, among other reasons, the Shares have
   not been registered with any regulatory authority of any state and,
   therefore, cannot be transferred or resold unless subsequently registered
   under applicable state securities laws or an exemption from such registration
   is available. The Company and the Shareholder also understand that neither
   VGS nor the Parent is under any obligation to register the Shares on their
   behalf or to assist them in complying with any exemption from registration
   under applicable state securities laws.

         (g) The Company and the Shareholder recognize that no federal or state
   agency has recommended or endorsed the purchase of the Shares or passed upon
   the adequacy or accuracy of the information set forth herein, and that Parent
   is relying on the truth and accuracy of the representations, declarations and
   warranties made by the Company and the Shareholder as contained herein in
   issuing the Shares.

         (h) The Company and the Shareholder have at all times been given the
   opportunity to obtain reasonably requested additional information, to

                                           29
<PAGE>

   verify the accuracy of the information received and to ask questions of and
   receive answers from certain representatives of VGS and the Parent concerning
   the terms and conditions of the Company's and the Shareholder's investment in
   the Parent and the nature and prospects of Parent's business.

         (i) The Company and the Shareholder recognize that there may be no
   public market for the Shares, and that it is extremely unlikely that there
   will be such a market in the future since neither Parent nor VGS is under any
   obligation to register the Shares under the Act or any state securities laws,
   or to comply with any exemption available for the resale of capital stock of
   Parent without registration. The transferability of the Shares will also be
   restricted by contract. Furthermore, the laws of various states also may
   require transferees of the Shares to meet standards similar to those set
   forth in Section 3.24(e) above. Thus, the Company and the Shareholder realize
   that they cannot expect to be able to liquidate their investment in the
   Shares readily or at all in case of an emergency.

         (j) The Company and the Shareholder are purchasing the Shares for
   investment for their own account and not with a view to or for sale in
   connection with any distribution of the Shares to or for the accounts of
   others provided that the Company may distribute the Shares to the
   Shareholder. In addition to any other transfer restrictions applicable to the
   Shares pursuant to this Agreement or the Collateral Agreements, the Company
   and the Shareholder agree that they will not dispose of the Shares, or any
   portion thereof or interest therein, unless and until counsel for Parent
   shall have determined that the intended disposition is permissible and does
   not violate the Act or the rules and regulations of the Security and Exchange
   Commission thereunder, or the provisions of any applicable state securities
   laws, or any rules or regulations thereunder.

         (k) The Company and the Shareholder recognize that the purchase of the
   Shares is a speculative investment and any financial forecasts or other
   estimates which may have been made by VGS or Parent merely represent
   predictions of future events which may or may not occur and are based on
   assumptions which may or may not occur. As a consequence, the Company and the
   Shareholder acknowledge and agree that such financial forecasts or other
   estimates may not be relied upon to indicate the actual results which might
   be attained.

         (1) The Shareholder is a resident of the State of Maryland. The
   Shareholder understands and agrees that depending upon his state of
   residence, a legend in substantially the following form may be placed on all
   certificates evidencing the Shares:

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933,

                                           30
<PAGE>

      AS AMENDED (THE "ACT") NOR ANY APPLICABLE STATE SECURITIES LAWS BY REASON
      OF SPECIFIC EXEMPTIONS THEREUNDER RELATING TO THE LIMITED AVAILABILITY OF
      THE OFFERING. THESE SECURITIES CANNOT BE SOLD, TRANSFERRED OR OTHERWISE
      DISPOSED OF TO ANY PERSON OR ENTITY UNLESS SUBSEQUENTLY REGISTERED UNDER
      THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, IF SUCH REGISTRATION IS
      REQUIRED.

                  Shareholder agrees that the market for the Parent's products
                  and services is nationwide, so that this Section 6.01 applies
                  to his activities within the United States.

            (2)   Without the prior written consent of the Parent, the
                  Shareholder shall not, during the Non-Competition Period,
                  directly, indirectly, or in concert with any other Person
                  (including the Company and those persons or entities in actual

                  any Conflicting Services for any Customer of the Parent or any
                  of its Affiliates; (3) interfere with or disrupt, or attempt

            (3)   Without the prior written consent of the Parent, the
                  Shareholder shall not for a period beginning on the date
                  hereof and ending one (1) year from and after the "POST-
                  TERMINATION PERIOD" directly, indirectly, or in concert with
                  any other Person (including the Company and those persons or

                  Support Services, Inc., or TEKgroup International, Inc., or
                  any other company or other business directly engaged in public
                  relations or government relations automation), whether as a
                  proprietor, partner, co-venturer, financier, investor,
                  director, officer, employer, employee, servant, agent,
                  representative, consultant or otherwise offer employment to or
                  solicit (directly or indirectly, individually or in connection
                  with any new employer or other business partner) any
                  individual who is an employee of Controlled Group or had left
                  the employ of the Controlled Group within the preceding one
                  (1) year, regardless of who initiates the contact or how the
                  Person comes to the Shareholder's attention.

            (4)   The Shareholder acknowledges and agrees that the covenants
                  provided for in this Section 6.01 (a) are reasonable and
                  necessary in terms of time, area and line of business to
                  protect the Parent's trade secrets. The Shareholder further
                  acknowledges and agrees that such covenants are reasonable and
                  necessary in terms of time, area and line of business to
                  protect the legitimate business interests of Parent and its
                  Affiliates, which include its interests in protecting the
                  Parent's and its Affiliates' (1) valuable confidential
                  business information, (2) substantial

                                       37
<PAGE>

                  relationships with customers throughout the United States, and
                  (3) customer goodwill associated with the ongoing business of
                  the Parent. The Shareholder expressly authorizes the
                  enforcement of the covenants provided for in this Article 6 by
                  (A) Parent and its subsidiaries, (B) Parent's permitted
                  assigns, and (C) any successors to Parent's or Parent's
                  business. The Shareholder and Parent agree that they have
                  attempted to restrict the Shareholder's activities to a
                  reasonable degree appropriate to protect the interests of the
                  Parent, although they agree that others may disagree about
                  this determination. Therefore, the Shareholder and the Parent
                  agree that a court or other trier of fact, may modify and
                  enforce these restrictions to the minimum extent deemed
                  necessary to be found reasonable. If a court declines to
                  modify and enforce this Agreement as provided above, the
                  Shareholder and the Parent agree that this Agreement will be
                  automatically modified to provide the Parent with the maximum
                  protection of its business interests allowed by law and the
                  Shareholder agree to be bound by such Agreement as modified;
                  but in no event shall the Parent be entitled to greater rights
                  than it has under this Agreement.

            (5)   The Shareholder shall not directly or indirectly disparage the
                  Parent, any of its Affiliates or products, or any officer,
                  director, employee, shareholder or member of the Parent or its
                  Affiliates.

            (6)   The Shareholder shall not at any time divulge, communicate,
                  use to the detriment of Parent or for the benefit of any other
                  Person or Persons, or misuse in any way, any confidential
                  information pertaining to the Company. Any confidential
                  information or data now known or hereafter acquired by the
                  Shareholder with respect to the Company shall be deemed a
                  valuable, special and unique asset of Parent that is received
                  by such Shareholder in confidence and as a fiduciary, and such
                  Shareholder shall remain a fiduciary to Parent with respect to
                  all of such information.

            (7)   Notwithstanding anything in this Section 6.01 (a) to the
                  contrary, the Shareholder and the Company may continue to
                  perform the Contracts listed on Schedule 2.05(b) to the extent
                  such Contracts do not become Assigned Contracts; provided that
                  the Shareholder and the Company shall not

                                       38
<PAGE>

                  expand the scope of the services offered under such Contracts
                  as of the Closing.

         (b) Injunction. It is recognized and hereby acknowledged by the parties
   hereto that a breach or violation by the Shareholder of any or all of the
   covenants and agreements contained in this Section 6.01 may cause irreparable
   harm and damage to Parent in a monetary amount which may be virtually
   impossible to ascertain. As a result, the Shareholder recognizes and hereby
   acknowledges and agrees that the Parent, in addition to and not in limitation
   of any other rights, remedies or damages available to the Parent at law or in
   equity, shall be entitled to a temporary restraining order, preliminary
   injunction and permanent injunction in order to prevent or to restrain any
   such breach by the Shareholder, or by any or all of the Shareholder's
   partners, co-venturers, employers, employees, servants, agents,
   representatives and any and all Persons directly or indirectly acting for, on
   behalf of or with the Shareholder, and that the Parent shall not be required
   in connection with any such order or injunction to post a bond of any nature
   whatsoever. If the Parent enforces the provisions of this Section 6.01
   through a court order, the Shareholder agrees that the restrictions contained
   in this Section 6.01 shall remain in effect immediately following the end of
   the applicable three-year period (or one-year period, in the case of Section
   6.01(a)(3)), for an additional period equal to the number of days that begins
   with the date of the breach and ends with the earlier of (1) the date that
   the Shareholder consents to an injunction, or (2) the date of such order.

      Section 6.02. Notification to Customers. Within three (3) business days
after Closing, as mutually agreed by the parties hereto, the Company shall
execute and deliver to VGS letters to its customers and licensees in form and
content satisfactory to the Buyer advising of the transactions contemplated by
this Agreement and directing that all payments to the Company shall be made to
VGS, at the address supplied by VGS.

      Section 6.03. Publicity. The Company and the Shareholder acknowledge and
agree that after the Closing occurs, the Parent and VGS shall have the sole
right to determine the time, method and manner of communicating or announcing
the transactions contemplated by this Agreement to third parties, including but
not limited to the Company's customers. Without limiting the foregoing sentence,
neither the Company nor Shareholder shall issue or make, or cause to have issued
or made, any public release or other public announcement concerning this
Agreement or the transactions contemplated hereby, without the advance approval
in writing of the form and substance thereof by the Parent, except as required
by law (in which case, so far as possible, there shall be consultation among the
parties prior to such announcement).

      Section 6.04. Confidentiality. (a) After the Closing, the Company, the
Shareholder and their Affiliates will hold, and will use their best efforts to
cause

                                       39
<PAGE>

their respective officers, directors, employees, accountants, counsel,
consultants, advisors and agents to hold, in confidence, unless compelled to
disclose by judicial or administrative process or by other requirements of law,
all confidential documents and information concerning the Business except to the
extent that such information can be shown to have been in the public domain
through no fault of the Company or its Affiliates.

      Section 6.05. Access to Records. On and after the Closing Date, the
Company and the Shareholder will afford promptly to the Parent and VGS and their
agents reasonable access to their books of account, financial and other records
(including accountant's work papers), information, employees and auditors to the
extent necessary or useful for the Parent or VGS in connection with any audit,
investigation, dispute or litigation or any other reasonable business purpose
relating to the Business, the Purchased Assets or the Assumed Liabilities.

      Section 6.06. Use of Corporate Name and Trademarks.

         (a) After the Closing, and except to the extent expressly permitted by
   the License Agreement, the Company and the Shareholder shall not use the
   trademarks GNOSSOS, KEEP IN TOUCH or any of the marks or names set forth on
   Schedule 6.06. In addition, promptly after the Closing, the Company shall
   amend its certificate of incorporation so as to remove the word "Gnossos"
   from its corporate name.

         (b) Gnossos and Kantor jointly and severally agree to pay for all
   attorney's fees and costs and expenses (including all administrative filing
   fees and expenses) associated with the U.S. applications for the registration
   of each of the trademarks GNOSSOS (Serial No. 78498910) and KEEP IN TOUCH
   (Serial No. 78498916) before the U.S. Patent & Trademark Office, which
   applications were filed on or about October 13, 2004 (collectively the
   "GNOSSOS MARKS"), including any and all attorney's fees and costs in
   connection with any court or administrative actions or any other legal
   proceedings relating to the Gnossos Marks, including any opposition to
   registration of the Gnossos Marks; provided that, subject to Section 3(d) of
   the License Agreement, any fees, costs and expenses incurred after the
   registration of the Gnossos Marks shall be the responsibility of VGS.

           COVENANTS OF PARENT, VGS, THE COMPANY AND THE SHAREHOLDER

      Section 7.01. Further Assurances. Following the Closing, the Company, the
Shareholder, the Parent and VGS shall execute and deliver such documents, and
take such other action, as shall be reasonably requested by any other party
hereto to carry out the transactions contemplated by this Agreement. In

                                       40

particular, the Company and the Shareholder agree that the Company shall, at the
Parent's or VGS's request, take all actions to enforce any confidentiality,
non-competition, non-solicitation or similar right it may have against any
current or former employee or contractor of the Company; and to the maximum
extent permissible, the Parent and VGS shall be permitted to take any such
action in the name of and on behalf of the Company, and shall control any action
or proceeding commenced hereunder in the name of the Company.

      Section 7.02. Employee Matters.

         (a) Following Closing, the Company shall retain sole responsibility for
   the payment of any employee benefits or entitlement, including severance pay,
   accrued vacation, sick or holiday pay, to any employee pursuant to any
   employment agreement with any of the employees, Plan, or law or regulation as
   a result of the consummation of the transactions contemplated hereby.

         (b) The parties acknowledge that the transactions provided for in this
   Agreement may result in obligations on the part of the Company and one or
   more of the Plans that is a welfare benefit plan (within the meaning of
   Section 3(1) of ERISA) to comply with the health care continuation
   requirements of Part 6 of Title 1 of ERISA and Code Section 4980B, as
   applicable. The parties expressly agree that the Parent, VGS and the Parent's
   and VGS's benefit plans shall have no responsibility for compliance with such
   health care continuation requirements (1) for qualified beneficiaries who
   previously elected to receive continued coverage under the Company's ERISA
   benefit plans or who between the date of this Agreement and the Closing Date
   elect to receive continued coverage, or (2) with respect to those employees
   or former employees of the Company who may become eligible to receive such
   continued coverage as a result of the transactions provided for in this
   Agreement.

         (c) Nothing in this Agreement, express or implied, shall confer upon

   for any period, of any nature whatsoever.

      Section 7.03. Delivery of Property Received by the Company after Closing.

transferred or intended to be transferred to VGS as part of the Purchased Assets

      Section 7.04. Collection of Accounts Receivable. The Company hereby
assigns to the Parent all rights and responsibilities with respect to the
collection of all accounts receivable (the "RECEIVABLES"); it being understood
that any collections of accounts receivable from and after the Closing Date will
be applied first to the Receivables until paid in full. The Parent will use the
same level of effort to collect such Receivables that the Parent uses to collect
its own accounts receivable and, after the Closing Date, will pay the proceeds
from the Receivables (to the extent they are Excluded Assets) to the Company on
no less than a semimonthly basis; provided, however, that, with respect to any
Receivables that are not collected within 90 days after the Closing Date, the
Shareholder shall have the right to participate in collection calls to such
customers with the Parent's personnel.

      Section 7.05. Transition Services.

         (a) From and after the Closing and for a period of thirty (30) days
   thereafter, the Company shall provide VGS with the transition services
   described on Schedule 7.05 (the "TRANSITION SERVICES"). The Company shall use
   its reasonable efforts to ensure that the nature and quality of Transition
   Services provided to VGS by the Company's employees or contractors shall be
   undifferentiated as compared with the same services performed by such
   employees or contractors prior to the Closing Date (it being understood that
   the Company shall not be deemed in breach of its obligations under this
   Section 7.05 if the Company is unable to provide the foregoing services on
   account of the voluntary resignation by one or more of the Company's
   employees or contractors). The management of and control over the provision
   of the Transition Services shall reside solely with the Company. Without
   limiting the generality of the foregoing, all labor matters relating to
   employees and contractors of the Company and its Affiliates shall be within
   the exclusive control of the Company, and VGS and the Parent shall not take
   any action affecting such matters. The Company shall, at its own expense,
   employ and retain staff needed to perform the Transition Services.

         (b) Within seven (7) days of its receipt of a detailed invoice from the
   Company, VGS shall reimburse the Company for (1) the lease payments for the
   month of November 2004 due under each of Copier Lease, Office Lease and Phone
   Lease, in each case to the extent paid by the Company and (2) its actual
   out-of-pocket costs it incurs for the salaries, benefits and related payroll
   costs for those employees of the Company (other than the Shareholder)
   providing Transition Services (but not for increases in salary, bonuses or
   payments not in the usual and ordinary course of business), with such
   reimbursement to occur no later than seven (7) days after the Company has
   provided a reimbursement statement to the Parent.

      Section 7.06. Presentation to Parent's Investors. At the Shareholder's
request and during the one (1)-year period after the Closing Date, the Parent
will

                                       42

<PAGE>

use its reasonable efforts to arrange for a mutually-convenient one (1)-hour
presentation by the Shareholder to the Company's lead investors.

      Section 7.07. Shareholder's Use of Office Space. VGS will permit the
Shareholder to use his existing office rent free at the premises leased pursuant
to the Office Lease until the earlier to occur of (1) the termination of the
Consulting Agreement or (2) the termination of the Office Lease.

                                   ARTICLE 8
                           SURVIVAL; INDEMNIFICATION

      Section 8.01. Survival. The representations and warranties of the parties
hereto contained in this Agreement or in any certificate or other writing
delivered pursuant hereto or in connection herewith shall survive the Closing
until June 30, 2007; provided that (1) the representations and warranties in
Sections 3.01, 3.02, 3.03, 3.04, 3.05, 3.09, 3.16, 3.17, 3.19, 3.23, 3.24, 4.01,
4.02, 4.03, 4.05 and 4.06 shall survive indefinitely. Notwithstanding the
preceding sentence, any representation or warranty in respect of which indemnity
may be sought under this Agreement shall survive the time at which it would
otherwise terminate pursuant to the preceding sentence, if notice of the
inaccuracy thereof giving rise to such right of indemnity shall have been given
to the party against whom such indemnity may be sought prior to such time.

      Section 8.02. Indemnification.

         (a) The Company and the Shareholder hereby jointly and severally
   indemnify Buyer and its and their Affiliates, directors, officers and
   employees (the "BUYER INDEMNITEES") against and agrees to hold each of them
   harmless from any and all Damages incurred or suffered by any Buyer
   Indemnitee arising out of: (1) any misrepresentation or breach of warranty
   (each such misrepresentation and breach of warranty a "WARRANTY BREACH") or
   breach of covenant or agreement made or to be performed by the Shareholder
   and/or the Company pursuant to this Agreement or the Collateral Agreements;
   (2) the assets, business or operations of the Company prior to the Closing
   Date; (3) any Excluded Asset; (4) any Excluded Liability; or (5) the failure
   of the Company to be duly qualified to do business as a foreign corporation;
   provided that with respect to indemnification by the Company or the
   Shareholder for any Warranty Breach pursuant to Section 8.02(a): (A) the
   Company and the Shareholder shall not be liable unless the aggregate amount
   of Damages with respect to any Warranty Breach (determined without regard to
   any materiality qualification contained in any representation, warranty or
   covenant giving rise to the claim for indemnity hereunder) exceeds $33,000,
   it being understood that such amount shall be a deductible, and (B) the
   aggregate liability of the Company and the Shareholder to the Buyer
   Indemnitees for Warranty Breaches shall not exceed $3,300,000; provided,

                                       43

<PAGE>

   further, that the foregoing limitation on liability shall not apply to fraud
   or any breach of Section 3.09.

         (b) The Parent and VGS hereby jointly and severally indemnify the
   Shareholder, the Company and their Affiliates (the "SELLER INDEMNITEES")
   against and agrees to hold each of them harmless from any and all Damages
   incurred or suffered by the Seller Indemnitees arising out of any Warranty
   Breach or breach of covenant or agreement (including, without limiting the
   generality of the foregoing, payment of the Purchase Price and any Assumed
   Liabilities) made or to be performed by VGS pursuant to this Agreement;
   provided that with respect to indemnification by the Parent and VGS for any
   Warranty Breach pursuant to this Section, (1) the Parent and VGS shall not be
   liable unless the aggregate amount of Damages with respect to such Warranty
   Breaches (determined without regard to any materiality qualification
   contained in any representation, warranty or covenant giving rise to the
   claim for indemnity hereunder) exceeds $33,000, it being understood that such
   amount shall be a deductible, and (2) the aggregate liability of the Parent
   and VGS to the Seller Indemnitees for Warranty Breaches shall not exceed
   $3,300,000.

      Section 8.03. Procedures.

         (a) A party making a claim for indemnity under Section 8.02 is
   hereinafter referred to as an "INDEMNIFIED PARTY" and the party against whom
   such claim is asserted is hereinafter referred to as the "INDEMNIFYING
   PARTY." All claims by any Indemnified Party under Section 8.02 hereof shall
   be asserted and resolved in accordance with the following provisions. If any
   claim or demand for which an Indemnifying Party would be liable to an
   Indemnified Party is asserted against or sought to be collected from such
   Indemnified Party by a third party, said Indemnified Party shall with
   reasonable promptness notify in writing the Indemnifying Party of such claim
   or demand stating with reasonable specificity the circumstances of the
   Indemnified Party's claim for indemnification; provided, however, that any
   failure to give such notice will not waive any rights of the Indemnified
   Party except to the extent the rights of the Indemnifying Party are actually
   prejudiced or to the extent that any applicable period set forth in Section
   8.01 has expired without such notice being given. After receipt by the
   Indemnifying Party of such notice, then upon reasonable notice from the
   Indemnifying Party to the Indemnified Party, or upon the request of the
   Indemnified Party, the Indemnifying Party shall defend, manage and conduct
   any proceedings, negotiations or communications involving any claimant whose
   claim is the subject of the Indemnified Party's notice to the Indemnifying
   Party as set forth above, and shall take all actions necessary, including the
   posting of such bond or other security as may be required by any Governmental
   Authority, so as to enable the claim to be defended against or resolved
   without expense or other action by the Indemnified Party. Upon

<PAGE>

   request of the Indemnifying Party, the Indemnified Party shall, to the extent
   it may legally do so and to the extent that it is compensated in advance by
   the Indemnifying Party for any costs and expenses thereby incurred,

            (1)   take such action as the Indemnifying Party may reasonably
                  request in connection with such action,

            (2)   allow the Indemnifying Party to dispute such action in the
                  name of the Indemnified Party and to conduct a defense to such
                  action on behalf of the Indemnified Party, or

            (3)   render to the Indemnifying Party all such assistance as the
                  Indemnifying Party may reasonably request in connection with
                  such dispute and defense.

         (b) The Shareholder and the Company specifically agree that any claims
   due and owing for indemnification by the Parent or VGS against the
   Shareholder and the Company (or any of them) shall be first satisfied by
   deducting and otherwise offsetting such claims against the Holdback Amount;
   and to the extent that there remain unsatisfied indemnification claims after
   the deductions and set-offs described above, the Parent and VGS shall have
   full recourse against the Shareholder and the Company (including their assets
   of whatsoever kind or nature) for payment of such indemnification claims.
   Notwithstanding anything in this Agreement to the contrary, the Shareholder
   and the Company expressly agree that VGS or the Parent may settle or
   compromise any individual claim for indemnity they make hereunder to the
   extent that the amount of the settlement or compromise is less than or equal
   to $5,000 and the settlement or compromise does not impose any injunctive
   relief with respect to the Company or the Shareholder; provided that the
   aggregate amount of such claims that VGS or the Parent may settle or
   compromise pursuant to the foregoing sentence is $50,000.

      Section 8.04. Other Matters.

      (a) The indemnification provisions of this Article 8 shall be the sole and
exclusive remedy of the parties hereto for any breach of any representations or
warranties made by any other party hereto in this Agreement and each party
hereby waives all statutory, common law and other claims with respect thereto,
other than claims for indemnification pursuant to this Article 8; provided,
however, that the foregoing limitations shall not apply to any claim seeking
money damages for fraud or intentional misrepresentation by a party hereto or
for breach of any covenant.

      (b) Except for fraud or intentional misrepresentation, there shall be no
indemnification by any party hereto for any special, incidental, punitive or
consequential damages.

                                       45

<PAGE>

      (d) Any indemnification payment by the Company pursuant to shall be
treated as an adjustment to the Purchase Price hereunder for Tax purposes.

      (f) In calculating amounts payable to an Indemnified Party, the amount of
the indemnified Damages shall be computed net of payments that the Indemnified
Party receives under any insurance policy with respect to such Damages.

documents delivered pursuant hereto shall be governed by and construed in
accordance with the laws of the State of Maryland (excluding any conflict of law
rule or principle that would refer to the laws of another jurisdiction). Each
party hereto irrevocably submits to the jurisdiction of state and federal courts
located in the State of Maryland, in any action or proceeding arising out of or
relating to this Agreement or any of the Collateral Agreements, and each party
hereby irrevocably agrees that all claims in respect of any such action or
proceeding must be brought and/or defended in such court; provided, however,
that matters which are under the jurisdiction of the federal courts in Maryland

proceeding brought against such party in any such court. Each party hereto
agrees that a final judgment in any such suit, action or proceeding brought in
any such court shall be conclusive and binding upon such party and may be
enforced in any other courts to whose jurisdiction such party is or may be
subject by suit upon such judgment.

      Section 9.03. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED

constitutes the entire agreement between and among the parties hereto pertaining
to the subject matter hereof and supersedes all prior agreements (including the
Letter of Intent), understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof
except as set forth specifically herein or contemplated hereby. No

                                       47

<PAGE>

supplement, modification or waiver of this Agreement shall be binding unless
executed in writing by the party to be bound thereby. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision hereof (regardless of whether similar), nor shall any such
waiver constitute a continuing waiver unless otherwise expressly provided.

      Section 9.05. Binding Effect and Assignment. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
permitted successors and assigns; but neither this Agreement nor any of the
rights, benefits or obligations hereunder shall be assigned, by operation of law
or otherwise, by the Company or the Shareholder without the Buyer's written
consent. Nothing in this Agreement, express or implied, is intended to confer
upon any Person other than the parties hereto and their respective permitted
successors and assigns, any rights, benefits or obligations hereunder.

      Section 9.06. Remedies. The rights and remedies provided by this Agreement
are cumulative, and the use of any one right or remedy by any party hereto shall
not preclude or constitute a waiver of its right to use any or all other
remedies. Except as otherwise limited in Article 8 hereof, such rights and
remedies are given in addition to any other rights and remedies a party may have
by law, statute or otherwise.

      Section 9.07. Multiple Counterparts. This Agreement may be signed and
delivered, by facsimile or otherwise, in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Agreement shall become effective
when each party hereto shall have received a counterpart hereof (whether by
facsimile or otherwise) signed by the other party hereto.

      Section 9.08. Survival. Any provision of this Agreement which contemplates
performance or the existence of obligations after the Closing Date, and any and
all representations and warranties set forth in this Agreement, shall not be
deemed to be merged into or waived by the execution and delivery of the
instruments executed at the Closing, but shall expressly survive Closing and
shall be binding upon the party or parties obligated thereby in accordance with
the terms of this Agreement, subject to any limitations expressly set forth in
this Agreement.

      Section 9.09. Attorneys' Fees. In the event any suit or other legal
proceeding is brought for the enforcement of any of the provisions of this
Agreement, the parties hereto agree that the prevailing party or parties shall
be entitled to recover from the other party or parties upon final judgment on
the merits reasonable attorneys' fees (and sales taxes thereon, if any),
including attorneys' fees for any appeal, and costs incurred in bringing such
suit or proceeding. For the purposes of this Section 9.09, the Company and
Shareholder

                                       48

shall be jointly and severally liable for any payment due hereunder from the
Company and/or the Shareholder.

      Section 9.10. Bulk Sales; Transfer Taxes, (a) The Buyer and the Company
each hereby waive compliance by the Company with the provisions of the "bulk
sales," "bulk transfer" or similar laws of any state. The Company and the
Shareholder hereby jointly and severally agree to indemnify and hold VGS and its
Affiliates harmless against any and all Damages incurred or suffered by VGS or
any of its Affiliates as a result of any failure to comply with any such "bulk
sales," "bulk transfer" or similar laws.

      (b) The Company shall pay all transfer, documentary, sales, use, stamp,
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement when due.

      Section 9.11. Interpretation. The parties hereto acknowledge and agree
that (1) each party and its counsel reviewed and negotiated the terms and
provisions of this Agreement and have contributed to its revision; (2) any rule
of construction to the effect that any ambiguities are resolved against the
drafting party shall not be employed in the interpretation of this Agreement;
and (3) the terms and provisions of this Agreement shall be construed fairly as
to all parties hereto and not in favor of or against any party, regardless of
which party was generally responsible for the preparation of this Agreement.

      Section 9.12. Risk of Loss. Prior to the Closing, the risk of loss of
damage to, or destruction of, any and all of the Company's assets, including the
Properties, shall remain with the Company, and the legal doctrine known as the
"Doctrine of Equitable Conversion" shall not be applicable to this Agreement or
to any of the transactions contemplated hereby.

      Section 9.13. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated
so long as the economic or legal substance of the transactions contemplated
hereby is not affected in any manner materially adverse to any party. Upon such
a determination, the parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner in order that the transactions contemplated
hereby be consummated as originally contemplated to the fullest extent possible.

      Section 9.14. No Third Party Beneficiaries. No provision of this Agreement
is intended to confer upon any Person other than the parties hereto any rights
or remedies hereunder. Without limiting the foregoing, no provision of this
Agreement shall create any third party beneficiary or other rights in any
employee

                                       49

<PAGE>

or former employee (including any beneficiary or dependent thereof) of the
Company or of any of its affiliates in respect of continued employment (or
resumed employment) with either VGS or the Business or any of their Affiliates
and no provision of this Agreement shall create any such rights in any such
Persons in respect of any benefits that may be provided, directly or indirectly,
under any Plan or any plan or arrangement which may be established by VGS or any
of its Affiliates. No provision of this Agreement shall constitute a limitation
on rights to amend, modify or terminate after the Closing Date any such plans or
arrangements of VGS or any of its Affiliates.
