                  (f) Severability. Whenever possible, each provision or portion
of any provision of this  Agreement  will be interpreted in such manner as to be
effective and valid under  applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid,  illegal or  unenforceable in

invalidity,  illegality or unenforceability  will not affect any other provision
or portion of any provision in such  jurisdiction,  and this  Agreement  will be
reformed,  construed  and  enforced  in such  jurisdiction  as if such  invalid,
illegal or  unenforceable  provision or portion of any  provision  had near been

the aggrieved  party shall be entitled to the remedy of specific  performance of

thereof by any party shall not preclude the  simultaneous  or later  exercise of
any other such right, power or remedy by such party.

                  (i) No Waiver. The failure of any party hereto to exercise any
right,  power or remedy provided under this Agreement or otherwise  available in
respect  hereof at law or in equity,  or to insist upon  compliance by any other
party hereto with its obligations  hereunder,  and any custom or practice of the
parties at variance with the terms hereof, shall not constitute a waiver by such
party of its right to exercise  any such or other  right,  power or remedy or to
demand such compliance.

                  (j)  Governing  Law.  This  Agreement  shall be  governed  and
construed in accordance with the laws of the  Commonwealth of Virginia,  without
giving effect to the principles of conflicts of law thereof.

                  (k) Noncontravention.  Notwithstanding  anything herein to the

provisions of the Merger Agreement,  while acting in such capacity as a director
of the Company.

                  (l)  Further  Assurances.  From  time to  time,  at the  other
party's  request and without  further  consideration,  each party  hereto  shall
execute and deliver such  additional  documents and take all such further lawful
action as may be necessary or desirable to consummate and make effective, in the
most  expeditious  manner  practicable,  the  transactions  contemplated by this
Agreement.
