         WHEREAS, Parent, Merger Sub, and the Company desire to amend the Merger

         WHEREAS, in connection therewith Parent and Stockholder desire to amend

         SECTION 1: AMENDMENT TO AGREEMENT.  The Agreement is hereby amended

         (a) Section 1.01 of the Agreement is hereby amended by (i) replacing

                                    ARTICLE V

                               REGISTRATION RIGHTS

                           SECTION 5.01. SHELF REGISTRATION. (a) In the event
                  that Parent pays for the Shares being purchased by delivery of
                  shares of Parent Common Stock, Parent shall, within three

                                       10


   2



                  months following the Closing, file with the Securities and
                  Exchange Commission (the "COMMISSION") a shelf registration
                  statement on an appropriate form under Rule 415 under the
                  Securities Act, or any similar rule that may be adopted by the
                  Commission (a "SHELF REGISTRATION STATEMENT"), relating to the
                  resale of the Parent Shares by the Stockholder from time to
                  time in accordance with the methods of distribution set forth
                  in such Shelf Registration Statement and shall use its best
                  efforts to cause such Shelf Registration Statement to be
                  declared effective under the Securities Act as soon as
                  practicable thereafter; PROVIDED, HOWEVER, that Stockholder
                  shall not be entitled to have the Parent Shares held by it
                  covered by such Shelf Registration Statement unless
                  Stockholder is in compliance with Section 5.02(f) hereof.

                           (b) Parent shall use its best efforts to keep the
                  Shelf Registration Statement continuously effective in order
                  to permit the prospectus forming part thereof to be usable by
                  the Stockholders until the earliest to occur of the following:
                  (A) the two year anniversary of the Closing; (B) the earliest
                  time at which all the Parent Shares covered by the Shelf
                  Registration Statement have been sold pursuant to the Shelf
                  Registration Statement; and (C) the earliest time at which, in
                  the written opinion of independent counsel to Parent, all
                  outstanding Parent Shares held by persons that are not
                  affiliates of Parent may be resold without registration under
                  the Securities Act pursuant to Rule 144(k) under the
                  Securities Act or any successor provision thereto (in any such
                  case, such period being called the "EFFECTIVENESS PERIOD").
                  Parent shall be deemed not to have used its best efforts to
                  keep the Shelf Registration Statement effective during the
                  requisite period if Parent voluntarily takes any action that
                  would result in Stockholders of Parent Shares covered thereby
                  not being able to offer and sell any such Parent Shares during
                  that period, unless (i) such action is required by applicable
                  law, (ii) the continued effectiveness of the Shelf
                  Registration Statement would require Parent to disclose a
                  material financing, acquisition or other corporate
                  transaction, and the Board of Directors shall have determined
                  in good faith that such disclosure is not in the best
                  interests of Parent and its stockholders, or (iii) the Board
                  of Directors shall have determined in good faith that there is
                  a valid business purpose for such suspension.

                           SECTION 5.02. REGISTRATION PROCEDURES. In connection
                  with any Shelf Registration Statement, the following
                  provisions shall apply:

                         (a) Parent shall take such action as may be necessary
                  so that (i) any Shelf Registration Statement and any amendment
                  thereto and any prospectus forming part thereof and any
                  amendment or supplement thereto (and each report or other
                  document incorporated therein by reference in each case)
                  complies in all material respects with the Securities Act and
                  the Exchange Act, and the respective rules and regulations
                  thereunder, (ii) any Shelf Registration Statement and any
                  amendment thereto does not, when it becomes effective, contain
                  an untrue statement of a material fact or omit to state a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading and (iii) any
                  prospectus forming part of any Shelf Registration Statement,
                  and any amendment or supplement to such prospectus, does not
                  include an untrue statement of a material fact or omit to
                  state a material fact necessary in order to make the
                  statements, in the light of the circumstances under which they
                  were made, not misleading.

                         (b) Parent shall advise the Stockholder:

                                    (i) when a Shelf Registration Statement and
                           any amendment thereto has been filed with the
                           Commission and when the Shelf Registration Statement
                           or any post-effective amendment thereto has become
                           effective;

                                    (ii) upon the issuance by the Commission of
                           any stop order suspending effectiveness of the Shelf
                           Registration Statement or the initiation of any
                           proceedings for that purpose;

                                    (iii) upon the receipt by Parent of any
                           notification with respect to the suspension of the
                           qualification of the securities included therein for
                           sale in any jurisdiction or the initiation of any
                           proceeding for such purpose; and

                                     (iv) upon the happening of any event that
                           requires the making of any changes in the Shelf
                           Registration Statement or the prospectus so that, as
                           of such date, the Shelf Registration Statement and

                                       12

                           the prospectus do not contain an untrue statement of
                           a material fact and do not omit to state a material
                           fact required to be stated therein or necessary to
                           make the statements therein (in the case of the
                           prospectus, in light of the circumstances under which
                           they were made) not misleading (which advice shall be
                           accompanied by an instruction to suspend the use of
                           the prospectus until the requisite changes have been
                           made).

                           (c) Parent shall, during the Effectiveness Period,
                  deliver to Stockholder with respect to a Shelf Registration
                  Statement, without charge, as many copies of the prospectus
                  (including each preliminary prospectus) included in such Shelf
                  Registration Statement and any amendment or supplement thereto
                  as Stockholder may reasonably request; and Parent consents
                  (except during the continuance of any event described in
                  Section 5.02(b)(iv)) to the use of the prospectus or any
                  amendment or supplement thereto by Stockholder in connection
                  with the offering and sale of the Parent Shares covered by the
                  prospectus or any amendment or supplement thereto during the
                  Effectiveness Period.

                           (d) Prior to any offering of Parent Shares pursuant
                  to any Shelf Registration Statement, Parent shall register or
                  qualify or cooperate with the Stockholder and its counsel in
                  connection with the registration or qualification of such
                  Parent Shares for offer and sale under the securities or blue
                  sky laws of such jurisdictions as any such Stockholders
                  reasonably request in writing and do any and all other acts or
                  things necessary or advisable to enable the offer and sale in
                  such jurisdictions of the Parent Shares covered by such Shelf
                  Registration Statement; PROVIDED, HOWEVER, that in no event
                  shall Parent be obligated to (i) qualify as a foreign
                  corporation or as a dealer in securities in any jurisdiction
                  where it would not otherwise be required to so qualify but for
                  this Section 5.02(d), (ii) file any general consent to service
                  of process in any jurisdiction where it is not as of the date
                  hereof then so subject or (iii) subject itself to taxation in
                  any jurisdiction if it is not so subject.

                           (e) Upon the occurrence of any event contemplated by
                  Section 5.02(b)(iv) above, Parent shall promptly prepare a
                  post-effective amendment to any Shelf Registration Statement
                  or an amendment or supplement to the related prospectus or
                  file any other required document so that, as thereafter
                  delivered to

                                       13


   5



                  purchasers of the Parent Shares included therein, the
                  prospectus will not include an untrue statement of a material
                  fact or omit to state any material fact necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not misleading. If Parent notifies the
                  Stockholder of the occurrence of any event contemplated by
                  Section 5.02(b)(iv) above, the Stockholder shall suspend the
                  use of the prospectus until the requisite changes to the
                  prospectus have been made.

                           (f) Parent may require Stockholder with respect to a
                  Shelf Registration Statement to furnish to Parent such
                  information regarding the Stockholder and the distribution of
                  Parent Shares held by the Stockholder as may be required by
                  applicable law or regulation for inclusion in such Shelf
                  Registration Statement and Parent may exclude from such
                  registration the Parent Shares of any Stockholder that fails
                  to furnish such information within a reasonable time after
                  receiving such request.

                           (g) Parent will use its best efforts to cause the
                  Parent Shares to be listed on the New York Stock Exchange or
                  other stock exchange or trading system on which the Parent
                  Common Stock primarily trades on or prior to the effective
                  date of any Shelf Registration Statement hereunder."

         SECTION 2.  REPRESENTATIONS AND WARRANTIES.

         (a) REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER. Stockholder hereby
represents and warrants to Parent that: Stockholder has all necessary power and
