                                  ARTICLE VIII
 
                                INDEMNIFICATION
 
     8.1 INDEMNIFICATION GENERALLY. RESI on the one hand, and Alliance, on the
other hand (each an Indemnifying Party as defined below), shall indemnify the
other as follows:
 
          (a) Alliance will defend, indemnify and hold RESI harmless in respect
     of the aggregate of all indemnifiable damages of RESI. For this purpose,
     "indemnifiable damages" of RESI means the aggregate of all expenses,
     losses, costs, deficiencies, liabilities and damages (including related
     counsel fees and expenses) incurred or suffered by RESI resulting from (i)
     any inaccurate representation or warranty made by Alliance or the Alliance
     Companies, or pursuant to, this Agreement or (ii) any material default in
     the performance of any of the covenants or agreements made by Alliance or
     the Alliance Companies in this Agreement. Notwithstanding the foregoing,
     Alliance shall only be liable for indemnification to RESI under this
     Article IX to the extent the aggregate amount of the "indemnifiable
     damages" of RESI exceeds $500,000.
 
          (b) RESI will defend, indemnify and hold Alliance harmless in respect
     of all indemnifiable damages of Alliance. For this purpose, "indemnifiable
     damages" of Alliance means the aggregate of all expenses, losses, costs,
     deficiencies, liabilities and damages (including related counsel fees and
     expenses) incurred or suffered by Alliance resulting from (i) from any
     inaccurate representation or warranty made by RESI or the Merger Subs in,
     or pursuant to, this Agreement; or (ii) any default in the performance of
     any of the covenants or agreements made by RESI or the Merger Subs in this
     Agreement.
 
     8.2 INDEMNIFICATION PROCEDURES. Each Person entitled to indemnification
under this Section (an "Indemnified Party") shall give notice as promptly as
reasonably practicable to each party required to provide indemnification under
this Article VIII (an "Indemnifying Party") of any action commenced against or
by it in respect of which indemnity may be sought hereunder, but failure to so
notify an Indemnifying Party shall not relieve such Indemnifying Party from any
liability that it may have otherwise than on account of this Article VIII so
long as such failure shall not have materially prejudiced the position of the
Indemnifying Party. Upon such notification, the Indemnifying Party shall assume
the defense of such action if it is a claim brought by a third party. If and
after such assumption, the Indemnifying Party shall not be entitled to
reimbursement of any expenses incurred by it in connection with such action
except as described below. In any such action, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless (i) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the contrary or
(ii) the named parties in any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing or conflicting interests between them. The Indemnifying
Party shall not be liable for any settlement of any proceeding effected without
its written consent (which shall not be unreasonably withheld or delayed by such
Indemnifying Party), but if settled with such consent or if there be final
judgment for the plaintiff, the Indemnifying Party shall indemnify the
Indemnified Party from and against any loss, damage or liability by reason of
such settlement or judgment.
 
     8.3 SURVIVAL. The indemnification obligations of RESI and Alliance set
forth in this Article VIII shall survive through the period beginning on the
Closing Date and ending on April 1, 1998.

                       TERMINATION, AMENDMENT AND WAIVER
 
     9.1 TERMINATION. This Agreement may be terminated, and the transactions
contemplated hereby may be abandoned at any time prior to the Effective Time, as
follows:
 
          (a) by written agreement of the Parties;
 
          (b) by RESI or Alliance if the transactions contemplated by this
     Agreement have not been consummated on or before September 30, 1996;
     provided, however, that the right to terminate this Agreement shall not be
     available to a Party whose failure to fulfill any obligation under this
     Agreement has been the cause, or resulted in, the failure of the Effective
     Time to occur on or before such date;
 
          (c) by RESI, upon a breach of any representation, warranty, covenant
     or agreement on the part of Alliance or the Alliance Companies set forth in
     this Agreement, or if any representation or warranty of Alliance or the
     Alliance Companies shall have become untrue, in either case such that the
     conditions set forth in Section 7.2 would not be satisfied and would have a
     Material Adverse Effect on RESI (a "Terminating Alliance Breach");
     provided, however, that if such Terminating Alliance Breach is cured by
     Alliance or the Alliance Companies, as the case may be, within 60 calendar
     days after notice thereof through the continuous exercise of its best
     efforts, then RESI may not terminate this Agreement under this Section
     9.1(c); or
 
          (d) by Alliance, upon a breach of any representation, warranty,
     covenant or agreement on the part of RESI or the Merger Subs set forth in
     this Agreement, or if any representation or warranty of RESI or the Merger
     Subs shall have become untrue, in either case such that the conditions set
     forth in Section 7.3 would not be satisfied and would have a Material
     Adverse Effect on Alliance (a "Terminating RESI Breach"); provided,
     however, that if such Terminating RESI Breach is cured by RESI or the
     Merger Subs as the case may be, within 60 calendar days after notice
     thereof through the continuous exercise of its best efforts then, Alliance
     may not terminate this Agreement under this Section 9.1(d).
 
     9.2 EFFECT OF TERMINATION.
 
          (a) If this Agreement is validly terminated pursuant to Section 9.1
     hereof, this Agreement will terminate and no Party hereto will have any
     liability to the other Parties hereto except that any such termination
     shall be without prejudice to any claim which either Party may have against
     the other for breach of this Agreement (or any representations, warranty,
     covenant, or agreement included herein).
 
          (b) All reasonable out-of-pocket expenses incurred in connection with
     this Agreement and the transactions contemplated hereby by a nonbreaching
     Party who terminates this Agreement pursuant to Section 9.1 hereof will be
     reimbursed promptly by the breaching Party.

fully rely on the representations, warranties, covenants and agreements of the

   26
 
     10.3 REMEDIES.
 
          (a) Each Party acknowledges that the other Parties would not have an
     adequate remedy at law for money damages in the event that any of the
     covenants or agreements in this Agreement of such Party was not performed
     in accordance with its terms, and it is therefore agreed that each Party in
     addition to and without limiting any other remedy or right any Party may
     have, shall have the right to an injunction or other equitable relief in
     any court of competent jurisdiction, enjoining any such breach and
     enforcing specifically the terms and provisions hereof, and each Party
     hereby waives any and all defenses it may have on the ground of lack of
     jurisdiction or competence of the court to grant such an injunction or
     other equitable relief.
 
          (b) All rights, powers and remedies under this Agreement or otherwise
     available in respect hereof at law or in equity shall be cumulative and not
     alternative, and the exercise or beginning of the exercise of any thereof
     by any Party shall not preclude the simultaneous or later exercise of any
     other such right, power or remedy by any Party.
 
     10.4 ENTIRE AGREEMENT. This Agreement (including the exhibits and schedules
attached hereto) and other documents delivered at the Closing pursuant hereto,
contain the entire understanding of the Parties in respect of this Agreement's
subject matter and supersede all prior agreements and understandings between or
among the Parties with respect to such subject matter. The exhibits and
schedules constitute a part hereof as though set forth in full above.
 
     10.5 EXPENSES. Except as otherwise provided herein, the Parties shall pay
their own fees, costs, and expenses incurred in connection with this Agreement
and all investigations and proceedings in connection therewith, including

supplemented, canceled or discharged, except by written instrument executed by
all of the Parties. No failure to exercise, and no delay in exercising, any
right, power or privilege under this Agreement shall operate as a waiver, nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude the exercise of any other right, power or privilege. No waiver of any
breach of any provision shall be deemed to be a waiver of any preceding or
succeeding breach of the same or any other provisions, nor shall any waiver be
implied from any course of dealing between the Parties. No extension of time for
performance of any obligations or other acts hereunder or under any other
agreement shall be deemed to be an extension of the time for performance of any
other obligations or any other acts. The rights and remedies of the Parties
under this Agreement are in addition to all other rights and remedies, at law or
equity, that they may have against each other.
 
     10.7 BINDING EFFECT; ASSIGNMENT. The rights and obligations of this

of reference only and are not to be given any legal effect and shall not affect
the meaning or interpretation of this Agreement.
 
     10.10 GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH
AND GOVERNED FOR ALL PURPOSES BY THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO
CONTRACTS EXECUTED AND TO BE PERFORMED THEREIN.
 
                                       26
   27
 
     10.11 SEVERABILITY. The Parties stipulate that the terms and provisions of
this Agreement are fair and reasonable as of the date of this Agreement.
However, if any provision of this Agreement shall be determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions of this Agreement shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated. Moreover, if any of such provisions shall for any reason be
determined by a court of competent jurisdiction to be unenforceable because it
is deemed to be excessively broad or vague as to duration, geographical scope,
activity or subject, such provision shall be construed by limiting, reducing or
defining it, so as to be unenforceable.
