limitation, those which are based upon the claims asserted in the SCE Litigation
or relate in any way thereto ("Released Claims"). Released Claims include,
without limitation, all losses, costs, claims, issues, obligations or
liabilities, arising out of or related to (i) any alleged breach of the
Partnerships' partnership agreements, (ii) any alleged breach of the Operation
and Maintenance Agreements, (iii) the direct or indirect ownership of the
Partnerships or Partnership Interests, (iv) fees or overhead charges to the

hereinafter defined) and (vi) any cooperation, advice, testimony or any other
services provided in the future in connection with the SCE Litigation including,
without limitation, cooperation provided by Seller or its Representatives
pursuant to the last sentence of Section 6.11; but shall not include liabilities
solely for an intentional and material breach of the express representations
made in Article IV. Buyer acknowledges and agrees that this is a general release
of all claims it has or may have against Seller, except with respect to an
intentional and material breach of the express representations made by Seller in
Article IV. The term of this release shall be unlimited; provided, however, that
this release will be ineffective only if and only to the extent that all of the
following have occurred and are continuing: (a) Buyer is not in breach of the
terms of this Agreement (b) Buyer has provided Seller notice of a material
breach of this Agreement and an opportunity to cure, (c) Buyer properly
terminated this Agreement pursuant to Section 11.1 (a) (iv), and (d) Buyer has
obtained a final nonappealable judgment that Seller is in material breach of
this Agreement.

     As to all matters that are to become released pursuant to this Agreement,
the Caithness Releasing Parties hereby expressly waive any right or benefit
available to them in any capacity under the provisions of Section 1542 of the
Civil Code of California, which provides:

                                       10


     "A general release does not extend to claims which the creditor does not
     know or suspect to exist in his favor at the time of executing the release,
     which if known by him must have materially affected his settlement with the
     debtor."


     The Caithness Releasing Parties expressly waive any such right or benefit
available to it in any capacity under the comparable provisions of any other
state or federal law.

     Buyer shall cause any transferee of Buyer's (or the Affiliates' who are
executing the Acknowledgment and Agreement-Release set forth below) direct or
indirect interests in the Partnerships or Projects to independently so release
Seller by delivering a written release in the form set forth above.  Further
Buyer shall further use its best efforts to cause its other Affiliates and the
Partnerships to independently so release Seller by delivering a written release
in the form set forth above.

     6.5  Indemnity.  Buyer (and each of the Affiliates who are executing the
          ---------
Acknowledgment and Agreement-Indemnity set forth below) hereby agrees to
indemnify and defend, and shall use its best efforts to cause its other
Affiliates, the Companies and Partnerships to indemnify and defend, Seller for,
from and against all losses, costs (including attorneys' fees), claims, expenses
and liabilities incurred in connection with the SCE Litigation, or the Released
Claims or in connection with claims made by any Representative, partner,
subsidiary or affiliate of Buyer or any shareholder, member or Representative
thereof, as a result of Seller remaining a named party in the SCE Litigation or
otherwise.  The term of this indemnity shall be unlimited; provided, however,
that this indemnity will be ineffective only if and only to the extent that all
of the following have occurred and are continuing:  (a) Buyer is not in breach
of the terms of this Agreement (b) Buyer has provided Seller notice of a
material breach of this Agreement and an opportunity to cure, (c) Buyer properly
terminated this Agreement pursuant to Section 11.1 (a) (iv), and (d) Buyer has
obtained a final nonappealable judgment that Seller is in material breach of
this Agreement.  Buyer shall cause any transferee of Buyer's (or the Affiliates'
who are executing the Acknowledgment and Agreement-Indemnity set forth below)
direct or indirect interests in the Partnerships or Projects) to independently
so indemnify Seller by delivering a written indemnity in the form and substance
set forth herein.  Buyer agrees not to settle and to not permit the other
parties to the SCE Litigation to settle the SCE Litigation in whole or in part
without obtaining a dismissal with prejudice and a general release of Seller and
its Affiliates and Representatives, including a waiver of (S)1542 of the Civil
Code of California.

     6.6  Operations.  Seller is in the process of transferring all of its
          -----------
operating employees, agreements and permits related to the operation of the
Projects to Coso Operating Company, except for certain employees and resource
data and computer systems which it will, prior to Closing, determine to retain
for its other California geothermal facilities ("Retained Operations").  Seller
shall provide Buyer a schedule specifying employees, resource data or computer
systems which are to be deemed Retained Operations on or before the Closing
Date, which shall be reasonably acceptable to Buyer.  Seller and Buyer agree to
cooperate fully with each other to

                                       11


ensure that all rights and obligations with respect to such operating employees,
agreements and permits are transferred or otherwise assumed by Coso Operating
Company prior to the Closing or as soon as possible thereafter. To the extent
any portion of such employees, agreements or permits are not transferred to or
otherwise assumed by Coso Operating Company prior to the Closing Date, Seller
shall, for a reasonable period thereafter, perform, at Buyer's expense, such
transition services as are required to permit the continued right of the
Projects to operate the Projects under the existing agreements and permits, and
if Coso Operating Company continues to be managed by Seller after Closing or
Seller is required to directly provide management or operations oversight for
the Projects after the Closing Date, Buyer shall cause the Partnerships to make
monthly payments to the Seller of the fee and overhead amount as set forth in
the Budget (or a subsequent budget if greater) until such management or
oversight is no longer provided ("Transition Services"). Seller and Buyer also
agree to cooperate with respect to the Retained Operations and any related
transition services to be provided by Buyer to Seller which related services
will be at Seller's cost.

     6.7  Bonds and Other Security.  Buyer shall use its best efforts to, on or
          ------------------------
before the Closing Date, assume or replace all bonds, letters of credit,
guarantees or other security, and provide the release of Seller and its
affiliates, with respect to all agreements, permits, licenses, and approvals
provided by Seller or its affiliates related to the Partnership, Partnership
Interests or Projects including, without limitation, the CIAC tax indemnity and
guarantee agreements with Southern California Edison Company and other
obligations listed on Schedule 6.7.  To the extent Buyer has not provided such
replacements, assumptions and releases by the Closing Date, Buyer shall do so as
soon as possible following Closing and Buyer and the Affiliates executing the
Acknowledgment and Agreement-Indemnity set forth below shall fully indemnify
Seller and its Affiliates from all liabilities, costs and expenses in connection
therewith.


     6.8  FERC Recertification.  In connection with this Agreement, Buyer agree
          --------------------
to recertify the facility utilizing the self-certification procedure at its own
cost and expense and agrees that such recertification shall not be a condition
to Closing.

     6.9  Termination Rights.  If Seller becomes entitled to the Termination
          ------------------
Rights pursuant to Section 11 (b) (ii), (w) Buyer shall forfeit all rights
hereunder including its rights to the Deposit, or if the Deposit has not been
delivered, forfeit its rights hereunder and pay over to Seller the sum of
$5,000,000 in immediately available funds, (x) Buyer shall immediately pay to
Seller Five Million U.S. Dollars (US$5,000,000) in immediately payable funds
into such account as directed by the Seller as liquidated damages and (y) Seller
or its designee shall be entitled to receive a monthly payment equal to the
monthly operator fees and overheads and all of its current management committee
fees as currently set forth in the Budget (including the Base Fee therein) and
such payment shall escalate from year to year on January 1 of each year (with
the first adjustment effective January 1, 2000) based on the change in the
Consumer Price Index, and (z) Seller shall cause its Affiliates to waive any
right of first refusal it may claim to have with respect to Seller's interests
in the Partnerships and shall provide any consent reasonably required to
facilitate the transfer of Seller's direct or indirect interests in the
Partnerships (which

                                       12


waiver and agreement to consent shall not be assignable and shall expire one
year from the date of this Agreement).  Buyer shall cause the respective
Partnership management committees to take such actions as are required to
approve the Budget; provided, however, that if the release provided in Section
6.4 and the indemnity provided in Section 6.5 are ineffective pursuant to the
express provisions thereof, such action shall be null and void.

     6.10    Commitment to Close.  Buyer shall close on the acquisition of the
             -------------------
Stock and Partnership Interests on or before February 25, 1999, unless any
consents required under the Coso Funding Corp. financing arrangements have not
been received or any approval, notice or passage of time required by the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended, has not been
received; provided, however, that in order for Seller to permit Buyer to obtain
any extension of the Closing Date, Buyer must use its best efforts to obtain all
consents required and close as promptly as possible (pursuant to a schedule
mutually agreed to by January 22, 1999 which has an end date of February 25,
1999), including retaining, or partnering with, an operator acceptable to any
rating agencies or Coso Funding Corp. note or bond holders or letter of credit
bank group, if required to obtain such consents in which case the Closing Date
may be extended by Seller day for day from February 25, 1999 until two business
days after such consents or approvals are received, but in no event shall the
Closing Date be extended beyond May 31, 1999.

     6.11  Litigation Obligations.  Buyer shall use its best efforts to obtain
           ----------------------
the exclusion or dismissal with prejudice of Seller or its Representatives from
any dispute, action or litigation, pending or threatened, related in any way to
the Companies, Partnerships or Projects, including obtaining the dismissal with
prejudice of Seller from the SCE Litigation and agree that it will not permit
the SCE Litigation to be settled in whole or in part without the full and
complete release of Seller and its Affiliates and Representatives. Further
Seller agrees that Buyer shall be consulted as to all significant decisions
regarding the SCE Litigation prior to Closing and such decisions shall be
mutual. Seller shall include Buyer's designated litigation counsel in an update
status discussion concerning the SCE litigation on a weekly or such other basis
as the parties hereto may agree. Seller shall provide reasonable cooperation to
Buyer in connection with the SCE Litigation and the defense thereof, including,
without limitation, if not otherwise prohibited or restricted by a protective
order or otherwise by law, the following: providing to Buyer or Buyer's
Representatives reasonable access to originals or copies of any and all
documents in Seller's possession relating to the SCE Litigation and Seller's
defense thereof which are non-privileged or if privileged, constitute documents
created by or for counsel as part of counsel's representation of the
Partnerships; providing Buyer or Buyer's Representatives reasonable access to
all witnesses or other persons under Seller's control that have knowledge of any
matter which is the subject of the SCE Litigation or the defense thereof;
providing to Buyer or Buyer's Representatives reasonable opportunity to discuss,
consult or otherwise communicate with such of Seller's Representatives under
Seller's control that have knowledge pertaining to the SCE Litigation and
Buyer's defense thereof, and otherwise reasonably consult, meet and provide
reasonable assistance in the defense of the SCE Litigation. Buyer agrees to pay
all of Seller's out of pocket and third party costs

                                       13


in connection with Seller providing such cooperation. Buyer agrees to keep
Seller reasonably informed of significant issues in the litigation and any
decisions which could reasonably be expected to result in indemnity of Seller
hereunder.

     6.12  Post 1998 Partnership Distributions; Pay Over Assurance.  Seller and
           -------------------------------------------------------
Buyer acknowledge and agree that all partnership distributions in respect of the
Stock and Partnership Interests and all Partnership assets and liabilities
(except any intercompany balances between Seller and its affiliates which shall
be extinguished) for the period commencing after December 31, 1998 are
transferred to Buyer according to the terms of this Agreement, and accordingly,
Seller and Buyer agree that if any monies, properties, securities, proceeds or
any other benefits in respect of the interests of the Partnerships or the
Partnership Interests (for the period commencing after December 31, 1998) are
received by Seller or its affiliates, that Seller will immediately notify and
pay over the same to Buyer or to Buyer's nominee, and that if Seller incurs or
pays any costs or liabilities in respect of the Stock, Partnerships, Partnership
Interests or Projects after December 31, 1998, on receipt of notice thereof
Buyer shall promptly pay or reimburse Seller in full.  Notwithstanding the
foregoing, the parties expressly agree that all management fees, operating fees,
allocations of overhead and similar costs, expenses and reimbursements made in
accordance with the Budget and or, payable or accrued prior to Closing and not
otherwise paid or reimbursed in the ordinary course shall be paid to Seller by
the Companies and Partnerships at the Closing or within 30 days after Closing if
amounts are not determinable at Closing.

     6.13  Taxes. All Taxes which are or may become due in respect of the
           -----
Companies or their respective operations and assets, as reflected on Tax Returns
to be filed by the Seller for tax periods ending prior to January 1, 1999 will
be fully paid and discharged by Seller; provided, that it is understood that
Seller makes no representation or warranty in respect of Tax Returns or Taxes
due and payable by the Partnerships or entities in which it holds a partnership
interest and shall have no liability hereunder for any inaccuracy of such Tax
Returns or any failure of the Partnerships to pay such Taxes, and provided
further that, (i) Seller shall not be obligated to pay and discharge the
Companies' or Seller's allocable share of Taxes (including any adjustment to tax
credits or depletion allowance), arising in respect of the Partnerships or
Partnership Interests for tax periods ending prior to January 1, 1999, resulting
from any adjustments to Taxes arising from tax audits or similar proceedings and
the Companies' or Seller's allocable share of costs and expenses in connection
therewith, and (ii) Seller shall not be obligated to pay and discharge the
Companies' or Seller's allocable share of Taxes (including any adjustment to tax
credits or depletion allowance), arising in respect of the Partnerships or
Partnership Interests for any short period ending on or before the date of the
Closing and to the extent such Taxes under clause (i) or (ii) above are incurred
by Seller, Buyer shall immediately reimburse Seller for any costs for or related
to such Taxes which are in excess of the amount of Taxes which would have arisen
from the transactions contemplated herein that Seller would have paid if such
Taxes were not so incurred and (b) to the extent such Taxes under clause (i) and
(ii) result in a reduction in the amount of Taxes arising from the transactions
contemplated herein that Seller would have paid if such Taxes were not so
incurred, Seller shall immediately reimburse Buyer for any such Taxes. If Seller

                                       14


receives a refund of any Taxes of the Companies for any tax period ending on or
prior to the Closing, then Seller shall immediately pay such refunded Taxes to
Buyer reduced by the amount of any increase in the amount of Taxes arising from
the transaction contemplated herein that Seller will have paid because of such
refunded Taxes. In no event shall Buyer amend any prior year tax return without
Seller's written consent. Upon Closing, Buyer shall be responsible to prepare
and file all Tax Returns and make tax elections with respect to the Companies,
Partnership Interests and Partnerships for tax periods commencing on or ending
after December 31, 1998 (except for any such return that must be filed as part
of Sellers consolidated return), but shall cooperate with and obtain Seller's
prior concurrence for any Tax Returns to be filed with respect to any period
commencing prior to Closing.

     6.14  Exclusivity.  Following execution hereof and prior to Closing or
           -----------
notice of termination of this Agreement, Seller agrees not to negotiate with any
third parties regarding acquisition of an interest in the Projects.

          ------------------------------

          (a)  Books and Records.  Each party agrees that it will cooperate with
               -----------------
and make available to the other party, during normal business hours, all Books
and Records and other information retained and remaining in existence after the
Closing which are necessary or useful in connection with any tax inquiry, audit,

requiring such Books and Records and information for any reasonable business

bear all of the out-of-pocket costs and expenses reasonably incurred in
connection with providing such Books and Records and information. All
information received pursuant to this Section 9.1 shall be subject to the
confidentiality and general release provisions of this Agreement.

          (b)  Cooperation and Records Retention.  Buyer, Seller and the
               ---------------------------------
Companies shall (i) each provide the others with such assistance as may
reasonably be requested by any of them in connection with the preparation of any
return, audit, or other examination by any taxing authority or judicial or
administrative proceedings relating to liability for Taxes, (ii) each retain and
provide the others with any records or other information that may be reasonably

          ---------------------------------
certificate, document, exhibit or instrument or conveyance delivered by or on
behalf of the parties pursuant to this Agreement or in connection with the
transactions contemplated hereby shall be deemed to be representations and
warranties by the parties hereunder.  The representations, warranties, covenants
and agreements (including the indemnity provisions set forth in Section 6.7 and
9.3 hereof) of Buyer and Seller contained herein shall survive the consummation
of the transactions contemplated hereby and the Closing Date for a period of
five years following the Closing Date unless otherwise specified herein.

                                       17


     9.3  Indemnification.
          ---------------

          Each of Buyer and Seller hereby agree to fully indemnify, defend and
hold harmless the other against and in respect of any and all claims, demands,
losses, costs, expenses, obligations, liabilities, damages, recoveries and
deficiencies, including interest, penalties and reasonable attorneys' fees and
costs of investigation (as the same are incurred), that such other party shall
incur or suffer, which arise, result from, or relate to any inaccuracy in or
breach of, or failure by the indemnifying party to perform any of its
representations, warranties, covenants or promises in this Agreement; provided,
however such indemnity shall not apply to any sum so incurred or suffered to the
extent caused by the indemnified party's breach of such representations,
warranties, covenants or promises. The party to be indemnified shall promptly
notify the other party of the existence of any claim, demand or other matter to
which the other party's indemnification obligations would apply, and shall give
it a reasonable opportunity to defend and control the defense of the same at its
own expense and with counsel of its own selection; provided that the party to be
indemnified shall at all times also have the right to participate fully in the
defense at its own expense. Each party hereto agrees that, to the extent that it
is an indemnified party hereunder, it shall, at no cost to the indemnified party
other than out of pocket costs, provide prior reasonable cooperation to the
indemnifying party in connection with the indemnifying party's defense of any
indemnified matter, including, without limitation, providing such party with
access to any and all reasonably applicable non-privileged documents and
employee witnesses or other persons having knowledge of such indemnified matter
within the indemnified party's control, and providing to the indemnifying party
the reasonable opportunity to discuss, consult or otherwise communicate with any
of the indemnified party's Representatives under its control about the
indemnified matter, provided such communication is made in the presence of the
indemnified party. If a party shall, within a reasonable time after such notice,
fail to defend, the party to be indemnified shall have the right, but not the
obligation, to undertake the defense of, and to compromise or settle (exercising
reasonable business judgment), the claim or other matter on behalf, for the
account, and at the expense and risk of the other party. The indemnifying party
shall not settle any matter for which the indemnified party seeks indemnity
hereunder without the consent of the indemnified party unless such settlement
provides for a reasonably satisfactory release of the indemnified party. Buyer
shall cause any transferee of Buyer's (or the Affiliates' who are executing the
Acknowledgment and Agreement-Indemnity set forth below) direct or indirect
interests in the Partnerships or Projects to independently so release Seller by
delivering a written indemnity in the form set forth above. Further Buyer shall
further use its best efforts to cause its other Affiliates and the Partnerships
to independently so indemnify Seller by delivering a written indemnity in the
form set forth above.

               -----------
to the Closing:

               (i)    By mutual written consent of Buyer and Seller;

               (ii)   By Buyer or Seller if the Closing shall not have occurred
on or prior to May 31, 1999; provided, however, that this provision may be
                             --------  -------
extended by mutual agreement in writing by Buyer and Seller, and provided,
further, that this provision shall not be available to Buyer if Seller has the
right to terminate this Agreement under Subsection (iii) of this Section
11.1(a);

               (iii)  By Seller, at its option, if there is (x) a material
breach of any representation or warranty set forth herein (including the failure
to deliver the Deposit to Seller on or before January 22, 1999) or of any
covenant or agreement to be complied with or performed by Buyer pursuant to the
terms of this Agreement (including, without limitation, the failure to be ready
to close by the Closing Date) or (y) the failure of a condition set forth in
Article VII to be satisfied (and such condition is not waived in writing by
Seller) on or prior to the Closing Date, or (z) the occurrence of any event
which results

                                       19


or would result in the failure of a condition set forth in Article VII to be
satisfied on or prior to the Closing Date;

           (iv)   By Buyer, if there is a material breach by Seller of
(S)3.2(a)(b)(c), 6.2 or 6.14 of this Agreement.

     (b)  In the Event of Termination.  In the event of termination of this
          ---------------------------
Agreement as permitted by Subsection (a) of this Section 11.1:

           (i)     The confidentiality and release provisions of this Agreement
and the provisions of Sections 11 and 6.9 shall continue in full force and
effect;

           (ii) In the event of a termination by Seller pursuant to Subsection
(iii) (x), (y) or (z) of Section 11.1(a), (and provided that in the case of a
termination pursuant to Subsection (iii)(y) or (z), such termination shall
result from events referenced in Section 7.1), Buyer shall immediately upon
written notice by Seller forfeit its Deposit and pay Seller $5 million as
liquidated damages and Seller shall be entitled to the Termination Rights set
forth in Section 6.9 and Buyer agrees not dispute such payment;

           (iii)  In, and only in, the event of a termination by Seller solely
for reasons other than a termination that results from a breach of this
Agreement by Buyer, Seller shall refund the Deposit with interest thereon at the
rate of 5 percent per annum to the Buyer; and

           (iv) The parties expressly agree that specific performance or other
injunctive relief is not available hereunder and that damages will be the sole
remedy available to a party hereunder.

     11.2  Assignment.  Neither this Agreement nor any of the rights or
           ----------
obligations hereunder may be assigned by any party without the prior written
consent of the other parties; provided, however, that Buyer may, at its
election, direct Seller to transfer all or a portion of the Stock or Partnership
Interests to one or more designees who are affiliates of Buyer rather than to
Buyer in connection with the Closing (but no such transfer shall relieve Buyer
of any of its obligations hereunder). Subject to the foregoing, this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns, and no other person shall have any
right, benefit or obligation under this Agreement as a third party beneficiary
or otherwise. Buyer shall not transfer any of its interests in the Partnerships
or any interest in the Projects or the assets thereof without causing such
transferee to assume its obligations hereunder, provided, however, that Buyer
may assign its rights acquired pursuant hereto to a lender providing debt
financing necessary for the consummation of the transaction contemplated herein
without such lender assuming Buyer's obligations provided all Buyer's
obligations to Seller and the obligations to Seller of Buyer's Affiliates
executing the Acknowledgment and Release remain in effect.

     11.3  Notices.  All notices, requests, demands and other communications
           -------
which
                                       20

           -------------
the rights of the parties determined in accordance with the laws of the State of
California, except with respect to matters of law concerning the internal
corporate affairs of any corporate entity which is a party to or the subject of
this Agreement, and as to those matters the law of the jurisdiction under which
the respective entity derives its powers shall govern.

     11.5  Amendments and Waivers.  This Agreement may not be amended except by
           ----------------------
an instrument in writing signed on behalf of each of the parties hereto. No
amendment, supplement, modification or waiver of this Agreement shall be binding
unless executed in writing by the party to be bound thereby. No waiver of any of
the provisions of this Agreement shall be deemed or shall constitute a waiver of
any other

                                       21


provision hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver unless otherwise expressly provided.

     11.6  Multiple Counterparts.  This Agreement may be executed in one or more
           ---------------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     11.7  Expenses.  Each of Seller and Buyer shall pay their own legal,
           --------
accounting, out-of-pocket and other expenses incident to this Agreement and to
any action taken by or on behalf of such party in preparation for carrying this
Agreement into effect unless expressly provided otherwise herein.

     11.8  Invalidity.  In the event that any one or more of the provisions
           ----------
contained in this Agreement or in any other instrument referred to herein,
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, then to the maximum extent permitted by law, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Agreement or any other such instrument.

     11.9  Captions.  The titles, captions or headings of the Articles and
           --------
Sections herein are inserted for convenience of reference only and are not
intended to be a part of or to affect the meaning or interpretation of this
Agreement.

     11.10  Public Statements and Press Releases.  The parties hereto
            ------------------------------------
covenant and agree that, if either party plans to issue a press release or other
public announcement disclosing the execution of this agreement ("Initial
Release"), it shall provide a copy of such Initial Release to the other party
for review and comment in advance of issuance, provided, that neither party
hereto nor their respective Affiliates shall issue any Initial Release prior to
Buyer's deposit of $5,000,000 on or before January 22, 1999.  Following such
Initial Release, Buyer agrees that any future public announcements by it with
respect to the Companies or the business of the Partnerships shall be consistent
with its Initial Release, except as otherwise required by law, and Seller agrees
that Seller's future public announcements will be consistent with its
obligations as a public company.

     11.11  Confidential Information.  The parties each acknowledge that
            ------------------------
the Representatives of the parties are aware of and the Books and Records of the
Companies and Partnerships contain confidential and proprietary information
regarding the Companies and Partnerships and the business of the parties and
accordingly, the parties agree that they shall not, on or after the date hereof,
directly or indirectly, make disclosure of such confidential and proprietary
information to any third party except if compelled to do so by subpoena, court
order or similar binding legal process (issued or initiated by an unaffiliated
third party) in which case each party agrees to give the other party adequate
notice in order for such party to seek a protective order or similar protection
and, in connection therewith, each party agrees to reasonably cooperate with the
other party.  The parties each agree that, in the event of a breach or
threatened breach of this Section, the other party shall be entitled to
equitable relief, including injunction and specific performance, in addition to
all other remedies available at law or at

                                       22


equity. For purposes of this Section, confidential and proprietary information
shall not include information which is or becomes generally available to the
public other than through a breach of this Agreement.

     11.12  Cumulative Remedies.  All rights and remedies of either party
            -------------------
hereto are cumulative of each other and of every other right or remedy such
party may otherwise have at law or in equity, and the exercise of one or more
rights or remedies shall not prejudice or impair the concurrent or subsequent
exercise of other rights or remedies.

     11.13  Entire Agreement.  This Agreement and any other agreements or
            ----------------
minutes executed pursuant to the terms hereof including, without limitation,
agreements in the form attached as Exhibits hereto, constitute the entire
agreement and understanding of the parties hereto with respect to the subject
matter hereof.

     11.14  Survival.  The covenants contained in Article VI of this Agreement
            --------
shall survive Closing and the covenants contained in Sections 6.4, 6.9 and 11.1
shall survive termination of this Agreement and shall be enforceable by the
Buyer and Seller.
