instrument, then all signatories shall be jointly and severally liable

          11.  CONTROLLING LAW.  This Debenture and all matters related hereto
shall be governed, construed and interpreted strictly in accordance with the
laws of the State of Maryland, without regard to its principles of conflicts of
law.

          12.  PURPOSE OF INVESTMENT.  Each Borrower represents and warrants
that this Debenture evidences an investment made in the Borrowers for the
purpose of carrying on a business or commercial enterprise pursuant to Section
12-103(e) of the Commercial Law Article, Annotated Code of Maryland, as amended.

          13.  NO USURY.  This Debenture is subject to the express condition
that at no time shall any Borrower be obligated or required to pay interest
hereunder at a rate which could subject the Holder to either civil or criminal
liability as a result of being in excess of the maximum rate which such Borrower
is permitted by law to contract or agree to pay.  If, by the terms of this
Debenture, such Borrower is at any time required or obligated to pay interest at
a rate in excess of such maximum rate, the rate of interest under this Debenture
shall be deemed to be immediately reduced to such maximum rate, and interest
payable hereunder shall be computed at such maximum rate and the portion of all
prior interest payments in excess of such maximum rate shall be applied and
shall be deemed to have been payments in reduction of the principal balance of
this Debenture.
