      Section 3.2. Remedies on Default. Whenever any Event of Default shall have
occurred and be continuing, Ajit may, by written notice to LMI, declare the
entire indebtedness outstanding under the Note immediately due and payable; and
Ajit shall have all of the remedial rights of a creditor and secured party under
this Agreement, the Note, the Uniform Commercial Code as enacted in the
applicable jurisdiction governing this Agreement, and under other applicable
law, including, without limitation, (a) the right to apply to a court of equity
for injunctive relief; and (b) the right, without notice to LMI (any such notice
being expressly waived hereby) to set off and apply any or all money,
instruments, credits or other assets of LMI (including, without limitation
obligations owed by Ajit to LMI) against any obligations of LMI to Ajit, first
under this Agreement and then under any other instrument or agreement with LMI,

      Section 3.3. Exercise of Remedies. No right, remedy or power conferred
upon or reserved to Ajit under this Agreement or the Note or arising out of this
Agreement or the Note is intended to be exclusive of any other available right,
remedy or power, but each and every such

<PAGE>
                                     - 5 -


right, remedy or power will be cumulative and will be in addition to any other
right, remedy or power given under this Agreement or such Note or now or
hereafter existing at law or in equity or by statute. No delay or omission by
Ajit to exercise any right, remedy or power accruing upon any Event of Default
will impair any such right, remedy or power or be construed to be a waiver
thereof, unless such waiver is in writing, signed by Ajit, and then only to the
extent set forth therein. Any right, remedy or power of Ajit hereunder may be
exercised from time to time and as often as may be deemed expedient by Ajit, and
a waiver by Ajit on one occasion shall not be construed as a bar to, or waiver
of, any such exercise on any other occasion. In order to entitle Ajit to
exercise any right, remedy or power reserved to it under this Agreement or the
Note, it shall not be necessary to give any notice, other than such notice as
may be herein expressly required.

      Section 3.4. Fees and Expenses; Indemnification. In the event that Ajit
should engage attorneys or incur other expenses for the enforcement of
performance or observance of any obligation or agreement on the part of LMI
contained herein or in the Note, LMI agrees that it will, on demand, pay to Ajit
the reasonable fees of such attorneys and such other expenses so incurred,
whether or not suit is brought. LMI also agrees to indemnify and hold harmless
Ajit against any costs, expenses, fees, liabilities or penalties incurred by it
relating in any way to this Agreement.

agreement between the parties hereto relating to the subject matter hereof
superseding all prior or contemporaneous oral or written understandings with
respect to such subject matter, and no amendment or waiver of any provision of
this Agreement or the Note nor consent to any departure by LMI therefrom shall

determining any claim. Any controversy concerning whether an issue is arbitrable
shall be determined by the arbitrator(s). Judgment upon the arbitration award
may be entered in any court having jurisdiction. The institution and maintenance
of an action for judicial relief or pursuit of a provisional or ancillary remedy
shall not constitute a waiver of the right of any party, including the
plaintiff, to submit the controversy or claim to arbitration if any other party
contests such action for judicial relief. No provision of this Section shall
limit the right of any party to obtain provisional or ancillary remedies from a
court of competent jurisdiction before, after or during the pendency of any

local or federal court located within the State of Maryland. LMI also waives

consents that such process shall be made by certified mail, return receipt
requested, directed to LMI at the address above, and service so made shall be
deemed completed within ten (10) days after it has been mailed. Ajit and LMI,
after receiving the advice of their respective counsel, waive trial by jury in
all litigation in any court arising out of this Agreement, the Note, or any
other documents executed in connection with this Agreement.
