     Section 2.1. Agreement To Extend The Loan. Subject to the terms and
conditions stated herein, the LENDER agrees to extend the LOAN to the BORROWER.
The LENDER shall advance proceeds of the LOAN to the BORROWER by depositing into
the COMMERCIAL ACCOUNT or in accordance with such other procedures as may be
mutually agreed to between the LENDER and the BORROWER, such sums as the
BORROWER may request, provided that the aggregate outstanding principal balance
of the LOAN shall never exceed at any time the MAXIMUM LOAN AMOUNT. The BORROWER
shall not request or permit any advance of proceeds of 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 MAXIMUM LOAN AMOUNT. In the
event that the principal balance outstanding under the LOAN ever exceeds the
MAXIMUM LOAN AMOUNT, the BORROWER shall immediately, upon the demand of the
LENDER, reduce the principal balance of the LOAN to an amount which is not in
excess of the MAXIMUM LOAN AMOUNT. Any termination of the LOAN by the LENDER
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 accounts, and
shall in no way release, terminate, discharge or excuse the BORROWER from its
absolute duty to pay or perform the OBLIGATIONS.

          Section 2.1.1. Conditions Precedent To Each Advance. The obligation of
the LENDER to make any advances under the LOAN, including the initial advance,
shall be subject to each of the following conditions precedent:

               a. No Defaults Or Events Of Default. No event shall have occurred
on or prior to such date and be continuing on such date, and no condition shall
exist on such date, which constitutes a DEFAULT or EVENT OF DEFAULT.

               b. Continuing Accuracy Of Representations And Warranties. Each of
the representations and warranties made by or on behalf of the BORROWER and the
GUARANTOR to the LENDER in the LOAN DOCUMENTS shall be true and correct in all
material respects when made.

               c. Receipt Of Reports. The LENDER shall be in receipt of all
reports, financial statements, financial information and financial disclosures
required by the LOAN DOCUMENTS, except to the extent that the LENDER has waived
the receipt thereof.

                                      -10-



               d. No Illegalities. It shall not be unlawful for the LENDER to
perform any of the agreements or obligations imposed upon the LENDER by any of
the LOAN DOCUMENTS or for the BORROWER or the GUARANTORS to perform any of their
respective agreements or obligations as provided by the LOAN DOCUMENTS.

               e. No Material Adverse Event. No MATERIAL ADVERSE EVENT shall
have occurred and be then continuing.

          Section 2.1.2. Interest And Lender's Records. All sums advanced under
the LOAN shall be evidenced by, and shall be repaid with interest in accordance
with, the provisions of the 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 duties and obligations under the
LOAN DOCUMENTS. Interest accrued upon the LOAN shall be computed on outstanding
balances as reflected on the LENDER'S books and records.

          Section 2.1.3. Facility Fee. On each annual anniversary of the date of
CLOSING, while the LOAN is in existence and has not been terminated, until the
termination of the LOAN, the BORROWER shall pay to the LENDER a facility fee of
one-quarter of one percent (1/4%) of the DOLLAR CAP. 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, but is instead
intended as part of the compensation which is earned by the LENDER for agreeing
to provide the LOAN in accordance with the terms of the LOAN DOCUMENTS.

          Section 2.1.4. Commitment Fee. The BORROWER shall pay to the LENDER on
or before CLOSING a non-refundable and unconditional commitment fee of Twenty
Thousand Dollars ($20,000.00), 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 principal amount of
the LOAN.

          Section 2.1.5. Administration Fee. On the first day of each month
until the LOAN is terminated and paid in full, the BORROWER shall pay to the
LENDER an administration fee of Five Hundred Dollars ($500.00) per month.

          Section 2.1.6. Term. All sums outstanding under the LOAN shall be paid
in full on the earlier of: (a) the demand of the LENDER at any time following an
EVENT OF DEFAULT; or (b) sixty (60) calendar days after the demand of the LENDER
made when there are no EVENTS OF DEFAULT.

          Section 2.1.7. Purpose. The proceeds of the LOAN shall be used by the
BORROWER solely for funding the general working capital needs of the BORROWER.

     Section 2.2. Payments. All payments received by the LENDER which are to be
applied to reduce the OBLIGATIONS shall be credited to the balances due from the
BORROWER pursuant to the normal and customary practices of the LENDER, but shall
be provisional and shall not be considered final unless and until such payment
is not subject to avoidance under any provision of

                                      -11-



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 2.3. Advancements. If the BORROWER fails to materially perform any
of its agreements or covenants contained in this AGREEMENT or if the BORROWER
fails to protect or preserve the COLLATERAL or the status and priority of the
security interest of the LENDER in the COLLATERAL, the LENDER may make advances
to perform the same on behalf of the BORROWER to protect or preserve the
COLLATERAL or the status and priority of the security interest of the LENDER in
the COLLATERAL, and all sums so advanced shall immediately upon advance become
secured by the security interests granted in this AGREEMENT, and shall become
part of the principal amount owed to the LENDER with interest to be assessed at
the applicable rate thereon in accordance with the NOTE and subject to the terms
and provisions of this AGREEMENT and all of the LOAN DOCUMENTS. The BORROWER
shall repay on demand all sums so advanced on the BORROWER'S behalf, plus all
expenses or costs incurred by the LENDER, including reasonable legal fees, with
interest thereon at the highest rate authorized in the NOTE. The provisions of
this Section shall not be construed to prevent the institution of the rights and
remedies of the LENDER upon the occurrence of an EVENT OF DEFAULT. The
authorization contained in this Section is not intended to impose any duty or
obligation on the LENDER to perform any action or make any advancement on behalf
of the BORROWER and is intended to be for the sole benefit and protection of the
LENDER.

     Section 2.4. Automatic Debit. The BORROWER hereby irrevocably authorizes
the LENDER to debit the COMMERCIAL ACCOUNT to make payment of any and all sums
due under the NOTE when and as such sums are due and payable.

that may be owing at any time and from time to time by the LENDER to the
BORROWER in any capacity, including but not limited to any balance or share
belonging to the BORROWER of any deposit or other account with the LENDER, which
security interest shall be independent of and in addition to any right of
set-off to which the LENDER may be entitled. The LENDER shall have the right to
require the BORROWER to pledge and grant a security interest to the LENDER in
such additional security as the LENDER may request from time to time in the
event that the LENDER deems itself to be insecure.

provided for herein shall apply to the proceeds, including but not limited to

deposit into the COLLECTION ACCOUNT, immediately upon receipt thereof, all cash,
checks, drafts, and other instruments for the payment of money, properly

                             OF AN EVENT OF DEFAULT

     Section 8.1. Lender's Specific Rights And Remedies. In addition to all
other rights and remedies provided by LAW and the LOAN DOCUMENTS, upon the
occurrence of any EVENT OF DEFAULT, the LENDER may: (a) accelerate and call
immediately due and payable all or any part of the OBLIGATIONS; (b) 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 (c) exercise any rights of a
secured creditor under the Uniform Commercial Code, as adopted and amended in
Maryland, including the right to take possession of the COLLATERAL without the
use of judicial process or hearing of any kind and the right to require the
BORROWER to assemble the COLLATERAL at such place as the LENDER may specify.

     Section 8.2. Automatic Acceleration. Upon the occurrence of an EVENT OF
DEFAULT as described in Sections 7.9 or 7.10 of this AGREEMENT, the OBLIGATIONS
shall be automatically accelerated and due and payable without any notice,
demand or action of any type on the part of the LENDER.

     Section 8.3. Sale Of Collateral. In addition to any other remedy provided
herein, upon the occurrence of an EVENT OF DEFAULT, the LENDER, in a
commercially reasonable fashion, may sell at public or private sale or otherwise
realize upon, in Baltimore, Maryland, or elsewhere,

                                      -27-



the whole or, from time to time, any part of all COLLATERAL which is personal
property, or any interest which the BORROWER may have therein. Pending any such
action, the LENDER may collect and liquidate the COLLATERAL. After deducting
from the proceeds of sale or other disposition of such COLLATERAL all expenses,
including all reasonable expenses for legal services, the LENDER shall apply
such proceeds toward the satisfaction of the OBLIGATIONS. Any remainder of the
proceeds after satisfaction in full of the OBLIGATIONS shall be distributed as
required by applicable LAW. Notice of any sale or other disposition (other than
sales or other dispositions of COLLATERAL which is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized
market) shall be given to the BORROWER not less than ten (10) calendar days
before the time of any intended public sale or of the time after which any
intended private sale or other disposition of the COLLATERAL is to be made,
which the BORROWER hereby agrees shall be commercially reasonable notice of such
sale or other disposition. The BORROWER shall assemble, or shall cause to be
assembled, at the BORROWER'S own expense, the COLLATERAL at such place or places
as the LENDER shall designate. At any such sale or other disposition, the LENDER
may, to the extent permissible under applicable law, purchase the whole or any
part of the COLLATERAL, free from any right of redemption on the part of the
BORROWER, which right is hereby waived and released to the extent lawfully
permitted. Without limiting the generality of any of the rights and remedies
conferred upon the LENDER under this Section, the LENDER may, to the full extent
permitted by applicable law: (a) enter upon the premises of the BORROWER,
exclude therefrom the BORROWER or any PERSON connected therewith, and take
immediate possession of the COLLATERAL, either personally or by means of a
receiver appointed by a court of competent jurisdiction, using all necessary
force to do so; (b) at the LENDER'S option, use, operate, manage, and control
the COLLATERAL in any lawful manner; (c) collect and receive all income,
revenue, earnings, issues, and profits therefrom; and (d) maintain, alter or
remove the COLLATERAL as the LENDER may determine in the LENDER'S discretion.

     Section 8.4. 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.

                                    ARTICLE 9
                          GENERAL CONDITIONS AND TERMS

     Section 9.1. 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. The BORROWER shall pay the payments of the principal and interest to be
made upon the OBLIGATIONS, 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 shall
not: (a) suspend or discontinue any payments required by the LOAN DOCUMENTS; and
(b) fail to perform and observe all of the BORROWER'S covenants and agreements
set forth in the LOAN DOCUMENTS.

     Section 9.2. Indemnity. The BORROWER agrees to defend, indemnify and hold
harmless the LENDER and the entities affiliated with the LENDER and all of the
LENDER'S and its affiliated entities' employees, agents, officers and directors,
from and against any losses, penalties, fines, liabilities, settlements,
damages, costs and expenses, suffered in connection with any claim,

                                      -28-



investigation, litigation or other proceeding (whether or not the LENDER or an
affiliated entity is a party thereto) and the prosecution and defense thereof,
arising out of or in any way connected with any LOAN DOCUMENT, including without
limitation reasonable attorneys' and consultant's fees, except to the extent
that any of the foregoing directly result from the gross negligence or willful
misconduct of the party seeking indemnification therefor. Notwithstanding any
termination of this AGREEMENT or payment and performance of the OBLIGATIONS, the
indemnities provided for herein shall continue in full force and effect and
shall protect all of the above-described PERSONS against events arising after
such termination, payment or performance as well as before.

     Section 9.3. Lender Expenses. All LENDER EXPENSES shall be paid by the
BORROWER, whether incurred prior to or after CLOSING, such that the subject
transactions shall at all times be cost free to the LENDER.

     Section 9.4. Authorization To Obtain Financial Information. The BORROWER
hereby irrevocably 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 such accounting firm in order to
obtain such information.

     Section 9.5. Incorporation; Construction Of 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 other LOAN DOCUMENT, 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 9.6. Waivers. The LENDER at any time or from time to time may waive
all or any rights under this AGREEMENT or any other LOAN DOCUMENT, 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 9.7. Continuing Obligation Of Borrower. The terms, conditions, and
covenants set forth herein and in the LOAN DOCUMENTS shall survive CLOSING and
shall constitute a continuing obligation of the BORROWER during the course of
the transactions contemplated herein. The security interests, liens and other
security provided by this AGREEMENT shall remain in effect so long as any
OBLIGATION, whether direct or contingent, is outstanding, unpaid or unsatisfied.
Upon the full and absolute payment (which payment is not subject to any possible
challenge or contest) of all of the OBLIGATIONS, the termination of any
agreement or relationship which may give rise to any future OBLIGATIONS, the
termination of any commitment or agreement of the LENDER to provide additional
credit to the BORROWER and the written request of the BORROWER, the LENDER shall
execute any document reasonably requested by BORROWER to authorize the BORROWER
to file terminations of all UCC-1 financing statements recorded evidencing the
liens granted herein, and terminate all of the LOAN DOCUMENTS, at which time the
BORROWER shall have no further duties or obligations to the LENDER thereunder.

     Section 9.8. 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 hereto, 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

                                      -29-

indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter related to
this AGREEMENT or any other LOAN DOCUMENT, including any action for recognition
or enforcement of any of the LENDER'S rights under the LOAN DOCUMENTS or any
judgment obtained by the LENDER in respect thereof, the BORROWER hereby:

          Section 9.9.1. Jurisdiction. Irrevocably submits to the non-exclusive
general jurisdiction of the courts of the State of Maryland and, if a basis for
federal jurisdiction exists at any time, the courts of the United States of

of Maryland.

          Section 9.9.3. Waiver Of Objections To Venue. Waives any right to
object to the maintenance of any suit in any of the courts specified in Section
9.9.2 above on the basis of improper venue or convenience of forum. The BORROWER
further agrees that it shall not institute any suit or other action against the
LENDER, in law or in equity, which is based directly or indirectly on this
AGREEMENT, any other LOAN DOCUMENT or any matter related to this AGREEMENT or
any other LOAN DOCUMENT, in any court other than a court specified in Section
9.9.2 above; provided, that in any instance in which there is then pending a
suit instituted by the LENDER against the BORROWER in a court other than a court
specified in Section 9.9.2 above, the BORROWER may file in such suit any
counterclaim which it has against the LENDER but only if such counterclaim is a
compulsory counterclaim and would be barred if not filed as a counterclaim in
such suit. The BORROWER agrees that any suit brought by it against the LENDER
not in accordance with this paragraph should be forthwith dismissed or
transferred to a court specified in Section 9.9.2 above.

     Section 9.10. Notices. Any notice required or permitted by or in connection

giving notice provided for in this Section) or by electronic mail, 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

Section and is refused by the intended recipient thereof, the notice,
nevertheless, shall be considered to have been given and shall be effective as
