                                    ---------
                      INDEMNIFICATION AND LEGAL PROCEEDINGS
                      -------------------------------------


7.1       Indemnification.  The  Parties  hereto  agree  to  indemnify  and save
          ---------------
harmless  the other  Parties  hereto  and  including,  where  applicable,  their
respective  affiliates,  directors,  officers,  employees  and agents (each such
party being an  "Indemnified  Party")  harmless from and against and agree to be
liable for any and all losses, claims,  actions,  suits,  proceedings,  damages,
liabilities or expenses of whatever nature or kind,  including any investigation
expenses  incurred by any Indemnified  Party, to which an Indemnified  Party may
become subject by reason of the terms and conditions of this Agreement.


7.2       No  Indemnification.  This  indemnity  will not apply in respect of an
          -------------------
Indemnified  Party in the  event  and to the  extent  that a court of  competent




<PAGE>


                                       21



jurisdiction in a final judgment shall determine that the Indemnified  Party was
grossly negligent or guilty of willful misconduct.


7.3       Claim of Indemnification.  The Parties hereto agree to waive any right
          ------------------------
they might have of first requiring the  Indemnified  Party to proceed against or
enforce any other right, power, remedy, security or claim payment from any other
person before claiming this indemnity.


7.4       Notice of Claim.  In case any action is brought against an Indemnified
          ---------------
Party in respect of which  indemnity  may be sought  against  any of the Parties
hereto, the Indemnified Party will give the relevant Party hereto prompt written
notice of any such action of which the Indemnified  Party has knowledge and such
Party will  undertake  the  investigation  and defense  thereof on behalf of the
Indemnified Party,  including the prompt consulting of counsel acceptable to the
Indemnified  Party  affected  and the  payment of all  expenses.  Failure by the
Indemnified  Party to so notify  shall  not  relieve  any  Party  hereto of such
Party's obligation of  indemnification  hereunder unless (and only to the extent
that) such failure  results in a forfeiture  by any Party hereto of  substantive
rights or defenses.


7.5       Settlement.  No admission of liability and no settlement of any action
          ----------
shall be made without the consent of each of the Parties  hereto and the consent
of the Indemnified Party affected, such consent not to be unreasonably withheld.


7.6       Legal Proceedings. Notwithstanding that the relevant Party hereto will
          -----------------
undertake the investigation and defense of any action, an Indemnified Party will
have the right to employ separate  counsel in any such action and participate in
the defense  thereof,  but the fees and  expenses of such counsel will be at the
expense of the Indemnified Party unless:

     (a)  such counsel has been authorized by the relevant Party hereto;

     (b)  the  relevant  Party  hereto has not assumed the defense of the action
          within a  reasonable  period  of time  after  receiving  notice of the
          action;

     (c)  the named parties to any such action include that any Party hereto and
          the  Indemnified  Party shall have been  advised by counsel that there
          may be a  conflict  of  interest  between  any  Party  hereto  and the
          Indemnified Party; or

     (d)  there are one or more  legal  defenses  available  to the  Indemnified
          Party which are  different  from or in addition to those  available to
          any Party hereto.


7.7       Contribution. If for any reason other than the gross negligence or bad
          ------------
faith of the  Indemnified  Party  being  the  primary  cause of the loss  claim,
damage, liability, cost or expense, the foregoing indemnification is unavailable
to the Indemnified  Party or  insufficient  to hold them harmless,  the relevant




<PAGE>


                                       22



Party hereto shall  contribute to the amount paid or payable by the  Indemnified
Party as a result of any and all such losses,  claim,  damages or liabilities in
such  proportion  as is  appropriate  to reflect not only the relative  benefits
received by any Party  hereto on the one hand and the  Indemnified  Party on the
other,  but  also  the  relative  fault  of  the  Parties  and  other  equitable
considerations  which  may  be  relevant.  Notwithstanding  the  foregoing,  the
relevant  Party  hereto  shall in any event  contribute  to the  amount  paid or
payable  by the  Indemnified  Party,  as a result  of the loss,  claim,  damage,
liability, cost or expense (other than a loss, claim, damage, liability, cost or
expenses, the primary cause of which is the gross negligence or bad faith of the
Indemnified  Party),  any  excess  of such  amount  over the  amount of the fees
actually received by the Indemnified Party hereunder.
