in their entirety, as follows:

                  (b) by either Base Ten or the Company if the Merger shall not

party is not otherwise in material breach of its obligations under this
Agreement;

                  (c) by either Base Ten or the Company if this Agreement is not

                  (a) Waivers, Amendments to be in Writing. No waiver,
amendment, modification or supplement of this Amendment No. 2 will be binding

forth in writing and is executed by such Party.

                  (b) Successors and Assigns. Except as otherwise expressly
provided in this Amendment No. 2, all covenants and agreements set forth in this
Amendment No. 2 by or on behalf of the Company and Base Ten will bind and inure
to the benefit of the respective successors and assigns of the Company and Base
Ten, whether so expressed or not. Notwithstanding the foregoing, neither this
Amendment No. 2 nor any of the rights, interests or obligations hereunder may be
assigned by either party without the prior written consent of the other party.


                                       2


                  (c) Governing Law. This Amendment No. 2 will be governed by
and construed in accordance with the domestic laws of the State of New Jersey,
without giving effect to any choice of law or conflict rule of any jurisdiction
that would cause the laws of any other jurisdiction to be applied. In
furtherance of the foregoing, the internal law of the State of New Jersey will
control the interpretation and construction of this Amendment No. 2, even if
under any choice of law or conflict of law analysis, the substantive law of some
other jurisdiction would ordinarily apply.

                  (d) Jurisdiction. Each of the Parties hereby (i) irrevocably
submits to the jurisdiction of the state courts of, and the federal courts
located in, the State of New Jersey in any action or proceeding arising out of
or relating to, this Amendment No. 2, (ii) waives, and agrees to assert, by way
of motion, as a defense, or otherwise, in any such suit, action or proceeding,
any claim that it is not subject personally to the jurisdiction of the
above-named courts, that its property is exempt or immune from attachment or
execution, that the suit, action or proceeding is brought in an inconvenient
forum, that the venue of the suit, action or proceeding is improper or that this
Amendment No. 2 or the subject matter hereof may not be enforced in or by such
court, and waives and agrees not to seek any review by any court of any other
jurisdiction which may be called upon to grant an enforcement of the judgment of
any such court.

                  (e) Ratification; Interpretation. Except as expressly modified
by this Amendment No. 2, the Amended and Restated Merger Agreement and Amendment
No. 1 shall remain in full force and effect, and the terms and provisions
thereof are hereby ratified and affirmed in all respects. Without limiting the
generality of the foregoing, the parties agree that in the event of a conflict
between any provision of the Amended and Restated Merger Agreement, Amendment
No. 1, and this Amendment No. 2, the provisions of this Amendment No. 2 shall
control.

                  (f) Severability of Provisions. If any provision of this
Amendment No. 2 is held to be invalid for any reason whatsoever, then such
provision will be deemed severable from the remaining provisions of this
Amendment No. 2 and will in no way affect the validity or enforceability of any
other provision of this Amendment No. 2.

                  (g) Counterparts. The Parties may execute this Amendment No. 2
in separate counterparts (no one of which need contain the signatures of all
Parties), each of which will be an original and all of which together will
constitute one and the same instrument.

                  (h) Headings. The headings used in this Amendment No. 2 are
for the purpose of reference only and will not affect the meaning or
interpretation of any provision of this Amendment No. 2.
