harmless from and against the amount of any actual (or potential in the case of
any litigation or claims by any person not a party to this Agreement) damage,
loss, cost, or expense (including reasonable attorneys' fees and settlement

                           (i) Any failure by any party hereto, including, but
                  not limited to Fred Bergmann and John McCoskrie to perform,
                  abide by, or fulfill any of the agreements, covenants, or
                  obligations set forth in or entered into, in connection with
                  this Agreement to be so performed or fulfilled by any party
                  hereto, including, but not limited to Fred Bergmann and John

                                       10
<PAGE>

                           (ii) Any material inaccuracy in or breach of any of
                  the representations or warranties of set forth in this
                  Agreement, or any certificate or Schedule or other writing
                  furnished pursuant hereto.

                           (iii) Any liability or obligation for any tort or any
                  breach or violation of any contractual, quasi-contractual,
                  legal, fiduciary, or equitable duty, including, but not
                  limited to, Environmental Laws, by any party hereto,
                  including, but not limited to Fred Bergmann and John
                  McCoskrie, whether before, at, or after the Effective Time of
                  the Merger.

         2. NOTICE OF CLAIM. Any aggrieved party shall give prompt written
notice to the others of any claim (actual or threatened) or other event that in
the judgment of such party might result or has resulted in a loss by such party
hereunder, and Miracor shall have the right to assume the defense of such claim
or any litigation resulting therefrom; PROVIDED THAT counsel for Miracor, who
shall conduct the defense of such claim (actual, threatened, or asserted) or
litigation, shall be reasonably satisfactory to such aggrieved party, and such
aggrieved party may participate in such defense at their expense, and PROVIDED,
FURTHER, that the omission by an aggrieved to give notice as provided herein
shall not relieve Miracor of its obligations hereunder except to the extent that
the omission results in a failure of actual notice to the Miracor, and Miracor
is damaged solely as a result of the failure to give notice. Miracor, in the
defense of any such claim or litigation, shall not, except with the consent of
each aggrieved party, consent to the entry of any judgment or decree or enter
into any settlement that does not include as an unconditional term thereof the
giving by the claimant or plaintiff to the aggrieved party, or parties, as the
case may be, of a release from all liability in respect to such claim or
litigation, and Miracor and the other parties hereto shall not have liability
with respect to any payment made by an aggrieved party in connection with the
settlement, satisfaction, or compromise of any claim unless the Miracor shall
have approved thereof in advance in writing, which approval shall not
unreasonably be withheld or delayed. If the aggrieved party shall not have
received notice that the Miracor shall assume the defense of such claim within
twenty (20) days after the notice is sent to the Miracor of the existence of
such claim, the aggrieved party shall be free to proceed with the defense of
such claim. Each such notice shall be accompanied (or followed as promptly as is
reasonably practicable after the amount of such loss becomes determinable) by a
certificate signed by the aggrieved party and setting forth in reasonable detail
the calculation of the amount of such Loss in accordance with the provisions
hereof, and accompanied by copies of all relevant documents and records. The
omission to give such notice or provide such certificate by the aggrieved party
shall not relieve Miracor of its obligation under this Agreement except to the
extent such omission results in a failure of actual notice to the Miracor, and
Miracor is damaged solely by such failure to give notice. No loss shall be
considered to have occurred with respect to any payment made by any aggrieved
party in settlement, satisfaction, or compromise of any claim unless the Miracor
shall have approved thereof in advance and in writing.

         J. BROKERAGE FEE.

          Each party hereto, including, but not limited to Fred Bergmann and
John McCoskrie, represents that no broker has been involved in this transaction
and each party hereto, including, but not limited to Fred Bergmann and John
McCoskrie, agrees to indemnify and hold the others harmless from payment of any
brokerage fee, finder's fee, or commission claimed by any party who claims to
have been involved because of association with such party.

         This Agreement constitutes the entire agreement of the parties related
to the subject matter of this Agreement, supersedes all prior or contemporary
agreements, representations, warranties, covenants, and understandings of the
parties. This Agreement may not be amended, nor shall any waiver, change,
modification, consent, or discharge be effected, except by an instrument in
writing executed by or on behalf of the party against whom enforcement of any
amendment, waiver, change, modification, consent, or discharge is sought.

         Any waiver of any term or condition of this Agreement, or of the breach
of any covenant, representation, or warranty contained herein, in any one
instance, shall not operate as or be deemed to be or construed as a further or
continuing waiver of such term, condition, or breach of covenant,
representation, or warranty, nor shall any failure at any time or times to
enforce or require performance of any provision hereof operate as a waiver of or
affect in any manner such party's right at a later time to enforce or require
performance of such provision or of any other provision hereof; and no such
written waiver, unless it, by its own terms, explicitly provides to the
contrary, shall be construed to effect a continuing waiver of the provision
being waived and no such waiver in any instance shall constitute a waiver in any
other instance or for any other purpose or impair the right of the party against
whom such waiver is claimed in all other instances or for all other purposes to
require full compliance with such provision.

         L. ASSIGNMENT: SUCCESSORS AND ASSIGNS.

consent of the others. This Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their respective successors and permitted
assigns.

         M. SEVERABILITY.

         If any provision or provisions of this Agreement shall be, or shall be
found to be, invalid, inoperative, or unenforceable as applied to any particular
case in any jurisdiction or jurisdictions, or in all jurisdictions or in all
cases, because of the conflict of any provision with any constitution or statute
or rule of public policy or for any other reason, such circumstance shall not
have the effect of rendering the provision or provisions in question invalid,
inoperative, or unenforceable in any other jurisdiction or in any other case or
circumstance or of rendering any other provision or provisions herein contained
invalid, inoperative, or unenforceable to the extent that such other provisions
are not themselves actually in conflict with such constitution, statute, or rule
of public policy, but this Agreement shall be reformed and construed in any such
jurisdiction or case as if such invalid, inoperative, or unenforceable provision
had never been contained herein and such provision reformed so that it would be
valid, operative, and enforceable to the maximum extent permitted in such
jurisdiction or in such case.

         N. COUNTERPARTS.

         This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument, and in pleading or proving any provision of this
Agreement it shall not be necessary to produce more than one such counterpart.
