amount at the rate of the prime rate as published in the Wall Street Journal
plus six (6) percent per annum, compounded annually based on a 360-day year.
Interest shall commence with the date hereof and shall continue on the
outstanding principal until paid in full. 1. All payments of interest and
principal shall be in lawful money of the United States of America. All payments
shall be applied first to any fees and costs due hereunder, then to accrued
interest, and thereafter to principal. All payments shall be made to Payor at
8181 Professional Place, Suite 200, Landover, Maryland 20785, or at such other
address as may be designated by Holder.

     2. The entire outstanding principal balance of this note (the "Note") and
all unpaid accrued interest shall become fully due and payable on October 21,
2001 (the "Maturity Date"); provided, however, that repayment will be made in
twelve (12) equal semi-monthly payments of $6,250, plus accrued interest,
commencing on May 7, 2001 and continuing on May 21, 2001 and on the 7th and 21st
day of each succeeding month through October 21, 2001.

     3. At any time prior to the Maturity Date, Holder may, in its sole
discretion, elect to convert the outstanding principal balance of this Note, and
any accrued interest, into common shares of the stock of the Payor, which shares
shall be registered and freely transferable by the Holder at any time without
restriction, at a conversion price of seven cents ($0.07) per share. If, prior
to the Maturity Date, Payor should offer to its shareholders the right to
purchase any stock of the Payor, Holder may, in its sole discretion, elect to
convert the outstanding principal balance of this Note, and any accrued
interest, into shares of such stock, which shares shall be registered and freely
transferable by the Holder at any time without restriction, at a conversion
price of the lower of (a) seven cents ($0.07) per share or (b) the offering
price of such stock.

     4. Failure to pay any amount due hereunder, or to issue any stock pursuant
to the exercise of a right of conversion hereunder, shall constitute a default
(a "Default").

     5. In the event of any Default hereunder, Payor shall pay all reasonable
attorneys' fees and court costs incurred by Holder in enforcing and collecting
this Note.

     6. Payor hereby waives demand, notice, presentment, protest and notice of
dishonor.

     7. The terms of this Note shall be construed in accordance with the laws of
the State of Maryland, as applied to contracts entered into by Maryland
residents within the State of Maryland, which contracts are to be performed
entirely within the State of Maryland.

     8. Holder shall in no event be construed for any purpose to be a partner,
joint venturer or associate of Payor, it being the sole and express intention of
the parties to establish a relationship of debtor and creditor.

     9. Subject to the conversion rights set forth in Paragraph 3, this Note may
be prepaid by Payor at any time without penalty.
