      4.3 Procedures Relating to Indemnification.

            (a) In order to be entitled to indemnification under this Article V
in connection with a claim made by any Person against any other Person with
respect to which that other Person (an "Indemnified Party") is entitled to
indemnification pursuant to this Article V (any such claim, a "Third Party
Claim"), that Indemnified Party must do the following:

                  (1)   notify the Person or Persons obligated to indemnify it
                        (the "Indemnifying Party") in writing, and in reasonable
                        detail, of that Third Party Claim as soon as possible
                        but in any event within ten (10) Business Days after
                        receipt of notice of that Third Party Claim, except that
                        any failure to give any such notification will only
                        affect the Indemnifying Party's obligation to indemnify
                        the Indemnified Party if the Indemnifying Party has been
                        prejudiced as a result of that failure; and

                  (2)   deliver to the Indemnifying Party as soon as possible
                        but in any event within ten (10) Business Days after the
                        Indemnified Party receives them a copy of all notices
                        and documents (including court papers) delivered to that
                        Indemnified Party relating to that Third Party Claim.

            (b) In the event of a Third Party Claim against one or more
Indemnified Parties, the Indemnifying Party may participate in the defense of
that Third Party Claim and, if it so chooses, assume at its expense the defense
of that Third Party Claim with counsel selected by the Indemnifying Party and
reasonably satisfactory to the Indemnified Party. If the Indemnifying Party so
elects to assume the defense of a Third Party Claim, the Indemnifying Party will
not be liable to the Indemnified Party for any legal expenses subsequently
incurred by the Indemnified Party in connection with the defense of that Third
Party Claim, except that if, under applicable standards of professional conduct,
there exists a conflict on any significant issue between the Indemnified Party
and the Indemnifying Party in connection with that Third Party Claim, the
Indemnifying Party shall pay the reasonable fees and expenses of one additional
counsel to act with respect to that issue to the extent necessary to resolve
that conflict. If the Indemnifying Party assumes defense of any Third Party
Claim, the Indemnified Party will be entitled to participate in the defense of
that Third Party Claim and to employ counsel, at its own expense, separate from
counsel employed by the Indemnifying Party, it being understood that the
Indemnifying Party will be entitled to control that defense. If the Indemnifying
Party chooses to defend or prosecute a Third Party Claim, all the parties shall
cooperate in the defense or prosecution of that Third Party Claim, including by
retaining and providing to the Indemnifying Party records and information
reasonably relevant to that Third Party Claim, and making employees available on
a reasonably convenient basis. If the Indemnifying Party chooses to defend or
prosecute any Third Party Claim, the Indemnified Party will agree to any
settlement, compromise or discharge of that Third Party Claim that the
Indemnifying Party recommends, except that the Indemnifying Party may not
without the Indemnified Party's prior written consent


                                       11
<PAGE>

agree to entry of any judgment or enter into any settlement that provides for
injunctive or other nonmonetary relief affecting the Indemnified Party or that
does not include as an unconditional term that each claimant or plaintiff give
to the Indemnified Party a release from all liability with respect to that Third
Party Claim. Whether or not the Indemnifying Party has assumed the defense of a
Third Party Claim, the Indemnified Party shall not admit any liability with
respect to, or settle, compromise or discharge, that Third Party Claim without
the Indemnifying Party's prior written consent.

            (c) In order for any Indemnified Party to be entitled to any
indemnification under this Agreement in respect of a claim that does not involve
a Third Party Claim (a "Claim"), the Indemnified Party must reasonably promptly
notify the Indemnifying Party of that Claim, and describe in reasonable detail
the basis for that Claim, except that any failure to give any such notification
will only affect the Indemnifying Party's obligation to indemnify the
Indemnified Party if the Indemnifying Party has been prejudiced as a result of
that failure. If the Indemnifying Party does not dispute that the Indemnified
Party is entitled to indemnification with respect to that Claim by notice to the
Indemnified Party prior to the expiration of a thirty (30) Business Day period
following receipt by the Indemnifying Party of notice of that Claim from the
Indemnified Party, that Claim will be conclusively deemed a liability of the
Indemnifying Party and the Indemnifying Party shall pay the amount of that
liability to the Indemnified Party on demand or, in the case of any notice in
which the amount of the Claim (or any portion thereof) is estimated, on such
later date as the amount of the Claim (or any portion thereof) becomes finally
determined. If the Indemnifying Party has timely disputed its liability with
respect to the Claim, the Indemnifying Party and the Indemnified Party shall
proceed in good faith to negotiate a resolution of the Claim and, if the Claim
is not resolved through negotiations within thirty (30) Business Days following
receipt by the Indemnifying Party of notice of that Claim from the Indemnified
Party, the Indemnified Party may pursue such remedies as may be available to
enforce its rights under this Agreement.

delivering a copy of the process to the party to be served at the address and in
the manner provided for the giving of notices in Section 5.1. Nothing in this

      5.5 No Assignment. Neither party may assign to any Person any of his

be deemed to be an original and all of which taken together shall constitute but
one and the same instrument.

      5.7 Severability. If any provision of this Agreement is held invalid or

this Agreement will remain in full force and effect. Any provision of this
Agreement held invalid or unenforceable only in part or degree will remain in
full force and effect to the extent not held invalid or unenforceable.

      5.8 Waivers and Amendments. This Agreement may be amended, superceded,
canceled, renewed or extended, and the terms hereof may be waived, only by
written instrument signed by the Purchaser and the Seller. No delay on the part
of any party in exercising any right, power or privilege hereunder shall operate
as a waiver thereof, nor shall any waiver on the part of any party of any such
right, power or privilege, nor any single or partial exercise of any such right,
power or privilege, preclude any further exercise thereof or the exercise of any
other such right, power or privilege.

and the other agreements referred to in this Agreement (including the Employment
