                  At the Closing, in consideration of the sale of the
Partnership Interests,Buyers shall pay to Sellers One Hundred Eighteen Million
Dollars ($118,000,000.00) (the "Purchase Price"), subject to adjustment as

mutual agreement of Olympus and Olympus Holdings.

             2.2  Allocation of Purchase Price; Section 754 Election; Other Tax
Matters.

                  (a) The Purchase Price shall be allocated among the
Partnership's assets in the manner mutually agreed to by all of the parties on
the Closing Date and shall be set forth on Schedule 2.2. The allocation of the

to the Net Liability Adjustment (as hereinafter defined) to the extent such Net

increased by an amount equal to the Net Liability Adjustment to the extent such
Net Liability Adjustment is a positive amount as of October 1, 1997. For
purposes hereof, the Net Liability Adjustment shall be the number obtained by

Buyers a final calculation of the Net Liability Adjustment (the "Final
Calculation"), together with such supporting documentation as Buyers may
reasonably request. Should Buyers dispute Sellers' Final Calculation, Buyers
shall promptly, but in no event later than 45 days after receipt of the Final
Calculation (the "Grace Period"), deliver to Sellers written notice describing
in reasonable detail the dispute, together with Buyers' determination as to the
Final Calculation in reasonable detail. If the dispute is not resolved by the
parties within 20 days from the date of receipt by Sellers of written notice
from Buyers, the parties agree to engage promptly the Pittsburgh, Pennsylvania
office of Price Waterhouse or, if unavailable, another "big five" accounting
firm mutually acceptable to Sellers and Buyers (the "Independent Accountant") to
resolve the dispute within 30 days after such engagement. The Independent
Accountant's determination shall be final and binding on the parties. All fees
and costs of the Independent Accountant shall be borne equally by Buyers and
Sellers. Buyers shall not dispute Sellers' Final Calculation unless Sellers'
computation of the Final Calculation differs from Buyers' computation by more
than $1,000.00. If Buyers fail to notify Seller prior to the expiration of the
Grace Period that it disputes Sellers' Final Calculation, Sellers' Final
Calculation shall be deemed to be accepted by Buyers and shall be final and
binding on the parties.

             2.4  Expenses.

                  Any transfer, documentary, sales, use, registration, and other
such Taxes (as defined below) and related penalties, interest or additions
thereto, and recording or filing fees imposed upon the sale, assignment and
delivery of the Partnership Interests and the other transactions contemplated
hereby shall be paid by the Sellers.

             2.5  Closing; Date and Location.

                  The consummation of the transfer of the Partnership Interests
to Buyers and the receipt of the consideration therefor by Sellers shall
constitute the "Closing." Unless otherwise mutually agreed to by the parties,
the Closing shall take place at 10:00 a.m., local time, at the offices of
Buchanan Ingersoll Professional Corporation, 301 Grant Street, 20th Floor,
Pittsburgh, PA 15219. The parties agree to close the transactions contemplated
by this Agreement within five (5) days after all of the conditions to Closing
have been satisfied or waived, whichever shall later occur, which specified date

all of the existing governmental authorizations for construction, maintenance
and operation of the CATV systems of the Partnership (individually, a

Partnership and the political entity or authority which has granted each
Franchise. All governmental authorizations necessary or required for the
construction, maintenance and operation of the CATV systems of the Partnership
have been obtained by the Partnership, and are listed and identified in Schedule
5.2. All such agreements, statutes, ordinances, resolutions, licenses or permits
granting the Franchises are validly existing, legally enforceable obligations of
the Partnership and, to the best knowledge of Sellers, are validly existing,
legally enforceable obligations of the other parties thereto, in accordance with
their terms, granted and renewed in accordance with all applicable federal,
state and local laws, and the Partnership is validly and lawfully operating
under the provisions of the franchises and applicable law. Further, the
Partnership has obtained in accordance with all federal, state and local laws
all Franchises required for the lawful operation of the CATV systems of the
Partnership. Except as set forth on Schedule 5.2, none of the political entities
or authorities which have granted a Franchise have been, or have applied to be,
certified to regulate the CATV rates charged by the Partnership pursuant to the
Cable Television Consumer Protection and Competition Act of 1992 and the Rules
and Regulations of the Federal Communications Commission ("FCC").

                      Each of the Franchises expires on the dates set forth on
Schedule 5.2 attached hereto. The Partnership has duly complied with all of the
terms and conditions of the Franchises and has not done or performed any act
which would invalidate or impair its rights under, or give to the granting
authority the right to terminate, the Franchises. There is no pending assertion
or claim that operations pursuant to any Franchise have been improperly
conducted or maintained. All construction of distribution plant required by any
of the Franchises has been completed in accordance with the terms of such
Franchise.

                  (b) True, complete and correct copies of the Franchises, all
amendments, assignments and consents thereto and the latest rate change

all applicable foreign, federal, state and local laws, rules, regulations,
orders, writs, injunctions, ordinances or decrees of any governing authority,
federal, state or local court, or of any municipal or governmental departments,
commission, board, bureau, agency or municipality having jurisdiction over it or
its CATV systems.

             5.4  Subscribers.

                  As of October 1, 1997, the Partnership had 57,606 Equivalent
Basic Subscribers and, as of the Closing Date, there shall not be less than
57,447 Equivalent Basic Subscribers. The term "Equivalent Basic Subscribers"

residential subscribers for basic CATV service of the Partnership who have made
at least one monthly payment for service at the normal monthly rate for basic
service, to (ii) the result obtained by dividing the aggregate of the gross
monthly billing from bulk subscribers who have made at least one monthly payment

                  The Partnership has (i) duly filed all federal, state, local
and foreign tax returns and other reports required to be filed, and has timely
paid and will pay all Taxes (as defined below) with respect to its businesses
that have become or may become due and payable by it except such amounts as are
being contested diligently and in good faith and are not in the aggregate
material and (ii) received no written notice of, nor do the Sellers have any
knowledge of, any notice of deficiency or assessment, or proposed deficiency or
assessment, from any taxing authority with respect to the Partnership's
businesses. There are no property, sales, use or franchise fee or tax audits
pending with respect to the Partnership's businesses.

                  There are no unpaid Taxes which are or could become a lien on
the Partnership's assets, nor are there any Tax liens filed against the
Partnership's assets. There are no outstanding agreements or waivers extending
the statutory period of limitations applicable to any items of Taxes of the
Partnership, and neither the Partnership nor its partners have requested any
extension of time within which to file any Tax return, which return has not yet
been filed. Neither the Partnership nor the Sellers have been notified that any
taxing authority intends to audit the Partnership. The earliest year for which
the Internal Revenue Service may assess deficiencies against the Partnership is
1994. The charges, accruals and reserves with respect to Taxes on the books of
the Partnership are adequate (as determined in accordance with GAAP). All Taxes
that the Partnership is or was legally required to withhold or collect have been
duly withheld or collected and, to the extent required, have been paid to the
proper governmental authority. All individuals that the Partnership treats as

<PAGE>

independent contractors are not "employees" (within the meaning of Section
3121(d)(2)(1) of the Code or Section 3(6) of ERISA) for purposes of any federal,
state or local Taxes. There is no dispute or claim as to Tax liability of any
other person or entity as to which the Partnership may be liable or have an
indemnification obligation.

                  "Tax" or "Taxes" means all levies and assessments of any kind
or nature imposed by any governmental authority including, but not limited to,

financial condition or operations of the Partnership or its businesses since
September 30, 1997 other than changes arising from matters of a general economic
nature or matters caused by or arising from legislation, rulemaking or
regulation affecting the cable television industry generally, and since

of its CATV systems, and is licensed to operate all the facilities required by
law to be licensed including, without limitation, any business radio and any
cable television relay service system being operated as part of the
Partnership's CATV systems. No written requests have been received by the
Partnership during the three years preceding the date of this Agreement from the
FCC, the United States Copyright Office or any other person or entity
challenging or questioning the right of the Partnership to operate its CATV
systems or any FCC-licensed or registered facility used in conjunction with the
Partnership's operation of its CATV systems. Except for such noncompliance that
would not, individually or in the aggregate, have a material adverse effect on
the Partnership or operation of its CATV systems, the Partnership's operation of
its CATV systems is in compliance with the FCC's rules and regulations and the
provisions of the Communications Act of 1934, as amended. The Partnership has
not violated any laws or any duty or obligation with regard to protecting the
privacy rights of any past or present subscribers of the Partnership's CATV
systems.

                  5.7.2  The Partnership has conducted all system and microwave

required by the rules and regulations of the FCC, corrected any radiation
leakage of its CATV systems required to be corrected in connection with the

connection with the operation of its CATV systems, except for such noncompliance
that would not, individually or in the aggregate, have a material adverse effect
on the Partnership or operation of its CATV systems.

                  5.7.3  The Partnership has deposited with the United States
Copyright Office all statements of account and other documents and instruments,

United States Copyright Office required under the Copyright Act with respect to
the business and operation of its CATV systems as are required to obtain, hold
and maintain the compulsory copyright license for cable television systems
prescribed by Section 111 of the Copyright Act. The Partnership is in compliance
with the Copyright Act and the rules and regulations of the Copyright Office
with respect to operation of its CATV systems except for such noncompliance that
would not, individually or in the aggregate, have a material adverse effect on
the Partnership or operation of its CATV systems. The Partnership is entitled to
hold and does hold the compulsory copyright license described in Section 111 of
the Copyright Act, which compulsory copyright license is in full force and
effect and has not been revoked, canceled, encumbered or adversely affected in
any manner.

                  5.74  All broadcast television signals carried by the
Partnership's CATV systems are carried either pursuant to the must-carry
requirements or pursuant to executed retransmission consent agreements.

                  5.7.5  The operation of the Partnership's CATV systems has not
and does not violate the Communications Act of 1984, as amended, the Cable
Communications Policy Act of 1984, as amended, or the Cable Television Consumer
Protection and Competition Act of 1992, as amended (collectively, the "Cable

reasonably could not be expected to have a material adverse effect on the
Partnership or its CATV systems. Upon the written request of Buyers, Sellers

copies of all reports and filings for the past three years made or filed
pursuant to the Cable Act, the Communications Act or FCC rules or regulations
with respect to operation of the Partnership's CATV systems, copies of the

television industry generally, there is no litigation, at law or in equity, or
any proceedings before any court, commission or other governmental authority or
mediation or arbitration, pending or, to the best knowledge of Sellers,
threatened against the Partnership which (i) could impair materially the ability
of the parties to consummate the transactions contemplated by this Agreement,
(ii) could materially and adversely affect the Partnership, its assets or its
ability to operate its CATV systems or (iii) could result in the termination,

obligations with respect to the Franchises, licenses held by the Partnership or
material contracts of the Partnership. There is no suit, action or other
proceeding pending before any court or other governmental agency against the

funds, programs or arrangements which have been maintained, established or
contributed to by the ERISA Employer (collectively the "Plans"), have been made
available to the Buyer and are listed in Schedule 5.13. For purposes hereof,
ERISA Employer means Sellers and any entity which is a member of a controlled
group within the meaning of Section 414(b), (c), (m) or (o) of the Code.

such term is defined in Section 3(1) of ERISA, or (iii) a "multiemployer plan"
("Multiemployer Plan"), as such term is defined in Section 4001(a)(3) of ERISA.
The ERISA Employer does not and has not participated in any employee benefit
plan maintained by or subscribed to by any other employer.

                  (b) Each Plan has been administered, including the filing of

the ERISA Employer is required, under applicable law or under any Plan or any
agreement relating to any Plan as to which the ERISA Employer is a party, to

<PAGE>

contribute to each Plan as of the Closing Date. There have been no contributions
to any Plan in any form other than cash. No accumulated funding deficiency (as
defined in Section 302(a)(2) of ERISA and Section 412(a) of the Code), whether
or not waived, exists with respect to any Plan. There will be no change on or

any such Plan is maintained that will result in an increase in the liabilities
under such Plan.

                  (d) No assets of any Plan are invested, directly or
indirectly, in any obligation or security of the ERISA Employer or its
affiliates, or in real or personal property of the ERISA Employer or its
affiliates. With respect to any Plan, no insurance contract, annuity contract or

impose a penalty, discount or other reduction on account of the withdrawal of
assets from such organization or the change in investment of such assets.

                  (e) Neither the ERISA Employer nor any of its affiliates has
incurred or expects any liability to the Pension Benefit Guaranty Corporation
("PBGC"), except for required premium payments, which payments incurred or
accrued up to and including the Closing Date have been or will be timely paid by
the ERISA Employer. Neither the ERISA Employer nor any of its affiliates has
ceased operations at any facility or withdrawn from any Pension Plan in a manner
which could subject it to liability under Sections 4062, 4063 or 4064 of ERISA,
and there have been no events which might give rise to any liability of the
ERISA Employer or its affiliates to the PBGC under Title IV of ERISA or which
could be anticipated to result in any claims being made against the Buyers by
the PBGC. No Reportable Event (as such term is defined in Section 4043 of ERISA)
has occurred with respect to any Pension Plan. Neither the ERISA Employer nor
any of its affiliates has incurred any withdrawal liability (including any
contingent or secondary withdrawal liability) within the meaning of Section 4201
and 4204, nor avoided withdrawal liability by virtue of compliance with Section
4204, of ERISA with respect to any Multiemployer Plan.

                  (f) Neither the ERISA Employer, its affiliates nor any other
person has engaged in any transaction with respect to any Plan which would
subject the Partnership or any of its affiliates to a tax, penalty or liability
for prohibited transactions under ERISA or the Code, and no director, officer or
employee of the Partnership or any of its affiliates, to the extent that he is a
fiduciary with respect to any Plan, has breached any of his responsibilities or
obligations imposed upon fiduciaries under Title I of ERISA or which would
result in any claim being made under, by or on behalf of any Plan.

                  (g) No action has been taken, nor has there been any failure
to take any action, nor is any action or failure to take action anticipated,
that would subject any person (including but not limited to any Plan, any
fiduciary of a Plan, the Partnership and its affiliates) to any liability for
any income, excise or other tax or penalty with respect to the operation of, or
any transactions with, any Plan.

                  (h) There is no pending, or to the best knowledge of the
Sellers, threatened litigation concerning any Plan, and there have been no
written or oral communications concerning any Plan with the IRS, Department of
Labor or any other federal, state or local government entity.

                          SURVIVAL AND INDEMNIFICATION


             12.1 Survival of Representations and Warranties.
<PAGE>

                  All representations, warranties, covenants, indemnities and
agreements contained herein shall survive the consummation of the transactions
provided for in this Agreement; provided that the representations and warranties
contained in this Agreement shall expire and be extinguished one year after the

ownership, which shall survive forever, (ii) environmental matters, which shall
survive for three years, (iii) financial statement matters which shall survive
for two years and (iv) tax matters, which shall survive until the expiration of
the statute of limitations with respect to liabilities related thereto.

             12.2 Indemnification.

                  (a) Sellers, jointly and severally shall indemnify and hold
Buyers, and each of them, harmless from and against, on a net after Tax basis,
any and all claims, liabilities, damages, losses, deficiencies, suits,
proceedings, mediations, arbitrations, judgments, deficiencies, assessments,
investigations and expenses including, without limitation, reasonable attorneys'
fees and expenses and costs of suit whether suit is instituted or not and, if
instituted, whether at any trial or appellate level, and whether raised by the
parties hereto or a third party, incurred or suffered by the Buyers or any of
them (individually, a "Loss" and collectively, "Losses") arising from, in
connection with or as a result of (i) any inaccurate representations and
warranties made by the Sellers or any of them, (ii) any and all breaches of
covenants and agreements made by or on behalf of the Sellers or any of them in
this Agreement and (iii) regardless of whether it may also constitute a breach
or violation under Section 12.2(a)(i) or (ii), the operation, management or
ownership of the Partnership, arising out of or related to the period on or
prior to the Closing Date except for any obligations and liabilities taken into
account under Section 2.3 hereof and for obligations arising out of the business
activities of the Partnership subsequent to the Closing Date; provided that in
connection with the indemnification provided for in this Section, Sellers shall
not be obligated to indemnify Buyers for Losses subject to indemnification
thereunder once the total amount of Losses for which Sellers have provided
indemnification under this Section equals the Purchase Price ("Sellers' Cap").
Notwithstanding the foregoing of this Section, Buyers shall not be entitled to
be indemnified by Sellers for any Losses under this Section arising out of any
single claim or aggregate claims until the total amount of all such Losses
suffered or paid by Buyers exceeds $500,000 ("Sellers' Basket"). Buyers shall
then be entitled to be indemnified under this Section for all such Losses,
including those Losses in the Sellers' Basket.

                  (b) Buyers, jointly and severally shall indemnify and hold
Sellers, and each of them, harmless from and against, on a net after Tax basis,
any and all Losses arising from, in connection with or as a result of (i) any
inaccurate representations made by the Buyers or any of them, and (ii) any and
all breaches of covenants and agreements made by or on behalf of the Buyers or
any of them in this Agreement; provided that Buyers shall not be obligated to
indemnify Sellers for Losses subject to indemnification hereunder until the
total amount of Losses for which Buyers are to provide indemnification hereunder
equals $500,000 ("Buyers' Basket") and then Sellers shall be entitled to be
indemnified under this Section for all such Losses, including those Losses in
the Buyers' Basket..

             12.3 Indemnification with Respect to Third-Party Claims.
<PAGE>

                  (a) Definition. As used herein, a "Third-Party Claim" means a
Loss or potential Loss for which indemnification is claimed by any of Buyers or
Sellers (the "Indemnitee") under the provisions of this Article XII and which is
consequent to a claim against the Indemnitee by a person, corporation,
association, partnership or other business organization, or an individual, or a
government, any political subdivision thereof or a governmental agency by
commencement against the Indemnitee of a legal action, proceeding or
investigation, or receipt by the Indemnitee of an assertion of a claim for which
indemnification may be appropriate pursuant to this Article XII by Buyers,
Sellers, or any of them as the case may be (the "Indemnitor").

                  (b) Notice of Claim. The Indemnitee will give notice of a
Third-Party Claim to the Indemnitor, stating the nature thereof and enclosing
copies of any complaints, summons, written assertion of such Third-Party Claim
or similar document. No claim for indemnification on account of a Third-Party
Claim shall be made and no indemnification therefor shall be available under
this Article XII until the Indemnitee shall have given initial written notice of
its claim to the Indemnitor.

                  (c) Retention of Counsel by the Indemnitor. Except as
hereinafter provided, the Indemnitor shall engage counsel to defend a
Third-Party Claim, and shall provide notice to the Indemnitee not later than 15
business days following delivery by the Indemnitee to the Indemnitor of a notice
of a Third-Party Claim, such notice to include an acknowledgment by the
Indemnitor that it will be liable in full to the Indemnitee for any Losses in
connection with such Third-Party Claim. The Indemnitee will reasonably cooperate
with such counsel at the sole cost and expense of Indemnitor. The Indemnitor
will cause such counsel to consult with the Indemnitee as appropriate as to the
defense of such claim, and the Indemnitee may, at its own expenses, participate
in such defense, assistance or enforcement, but the Indemnitor shall control
such defense, assistance or enforcement. The Indemnitor will cause such counsel
engaged by the Indemnitor to keep the Indemnitee informed at all times of the
status of such defense, assistance or enforcement.

                  (d) Employment of Counsel by the Indemnitee.

                                       (i)   Notwithstanding the provision of
                           Section 12.3(c), the Indemnitee shall have the right
                           at the sole cost and expense of Indemnitor to engage
                           counsel and to control the defense of a Third-Party
                           Claim if the Indemnitor shall not have notified the
                           Indemnitee of its appointment of counsel and control
                           of the defense of a Third-Party Claim pursuant to
                           Section 12.3(c) within the time period therein
                           provided.

                                       (ii) Notwithstanding the engagement of
                           counsel by the Indemnitor, the Indemnitee shall have
                           the right, at its own expense, to engage counsel to
                           participate jointly with the Indemnitor in, and to
                           control jointly with the Indemnitor, the defenses of
                           a Third-Party Claim if (A) the Third-Party Claim
                           involves remedies other than monetary damages and
                           such remedies, in the Indemnitee's reasonable
                           judgment, could have an effect on the conduct of the
                           Indemnitee's business, or (B) the Third-Party Claim

<PAGE>

                           relates to acts, omissions, conditions, events or
                           other matters occurring after the Closing Date as
                           well as to acts, omissions, conditions, events or
                           other matters occurring prior to the Closing Date, or
                           (C) the Third Party Claim involves monetary damages
                           which could exceed Sellers' Cap or (D) if in any such
                           Third-Party Claim, the named parties to any such
                           proceeding (including any impleaded parties) include
                           both the Indemnitee and the Indemnitor or if the
                           Indemnitor proposes that the same counsel represent
                           both the Indemnitor and the Indemnitee and
                           representation of both parties by the same counsel
                           would be inappropriate due to actual or potential
                           differing interests between them.

                                       (iii) If the Indemnitee chooses to
                           exercise its right to appoint counsel under this
                           Section 12.3(d), the Indemnitee shall deliver notice
                           thereof to the Indemnitor setting forth in reasonable
                           detail why it believes that it has such right and the
                           name of the counsel it proposes to employ. The
                           Indemnitee may deliver such notice at any time that
                           the conditions to the exercise of such right appear
                           to be fulfilled, it being recognized that in the
                           course of litigation, the scope of litigation and the
                           amount at stake may change. The Indemnitee shall
                           thereupon have the right to appoint such counsel.

                                       (iv)  The reasonable fees and expenses of
                           counsel and any accountants, experts or consultants
                           engaged by the Indemnitee in accordance with Section
                           12.3(d)(i) in connection with defending a Third-Party
                           Claim shall be paid by the Indemnitor in accordance
                           with the provisions of this Article XII. If the
                           Indemnitee's employment of counsel is for a
                           Third-Party Claim of the type described in
                           subdivision (ii)(B) or (ii)(C) of this Section
                           12.3(d), then subject to the provisions of Section
                           12.3(e), the amount of fees and expenses so payable
                           by the Indemnitor shall be that fraction of the
                           aggregate of such fees and expenses, the numerator of
                           which is the portion of the amount of any judgment
                           on, or settlement of, such Third-Party Claim for
                           which the Indemnitee is indemnified pursuant to this
                           Article XII and the denominator of which is the total
                           amount of such judgment or settlement, but provided
                           further, if such defense of a Third-Party Claim is
                           successful (in the sense that as a consequence
                           thereof, there is no Loss (other than such fees and
                           expenses) for which the Indemnitee is indemnified
                           pursuant to this Article XII), the Indemnitee and the
                           Indemnitor will attempt in good faith to reach an
                           agreement on the amount of such fees and expenses so
                           payable by the Indemnitor.

                  (e) Settlement of Third-Party Claims.

                                       (i)   The Indemnitor may settle any
                           Third-Party Claim solely involving monetary damages
                           only if (A) the amount of such settlement is to be
                           paid entirely by the Indemnitor pursuant to this
                           Article XII and (B) Indemnitee is fully released from
                           the Third-Party Claim.
<PAGE>

                                       (ii)  The Indemnitor will not enter into
                           a settlement of a Third-Party Claim which involved a
                           non-monetary remedy or which will not be paid
                           entirely by the Indemnitor pursuant to this Article
                           XII without the written consent of the Indemnitee
                           (which consent shall not be unreasonably withheld,
                           delayed or conditioned).

                                       (iii) As to any Third-Party Claim of the
                           type described in subsection (ii)(B) or subsection
                           (ii)(C) of Section 12.3(d), the Indemnitee and the
                           Indemnitor shall consult as to any proposed
                           settlement. If the Indemnitee notifies the Indemnitor
                           that it wishes to accept a proposed settlement and
                           the Indemnitor is unwilling to do so, if the amount
                           for which the Third-Party Claim is ultimately
                           resolved is greater than the amount of which the
                           Indemnitee desired to settle, then (A) the Indemnitee
                           shall be liable only for the amount, if any, which it
                           would have paid had the Third-Party Claim been
                           settled as proposed by the Indemnitee, and (B) all
                           reasonable attorneys' fees and expenses and costs of
                           suit incurred by the Indemnitee subsequent to the
                           time of the proposed settlement shall be paid or
                           reimbursed by the Indemnitor.

                                       (iv)  In determining whether to accept or
                           reject any settlement proposal, each party shall act
                           in good faith and with due regard for the reasonable
                           commercial and financial interests of the other.

                  (f) Claims as to Which Indemnification is Partially Payable.
Notwithstanding the foregoing, in the event of any settlement of, or final
judgment with respect to, a Third-Party Claim which relates to acts, omissions,
conditions, events or other matters occurring both before and after the Closing
Date, the Indemnitee and the Indemnitor shall negotiate in good faith as to the
portion of such Third-Party Claim as to which such indemnification is payable.

                  (g) Cooperation, etc. The Indemnitee and the Indemnitor shall
reasonably cooperate with one another in good faith in connection with the
defense, compromise or settlement of any claim or action. Without limiting the
generality of the foregoing, the party controlling the defense or settlement of
any matter shall take steps reasonably designed to ensure that the other party
and its counsel are informed at all times of the status of such matter. Neither
party shall dispose of, compromise or settle any claim or action in a manner
that is not reasonable under the circumstances and in good faith. The Indemnitor
and Indemnitee shall enter into such confidentiality and other non-disclosure
agreements as the Indemnitee or Indemnitor, as the case may be, shall reasonably
request in order to protect trade secrets and other confidential or proprietary
information of the Indemnitee or Indemnitor, as the case may be.
