of such Shares.

          (b)  Promptly after the Closing and upon receipt of evidence
satisfactory to the Surviving Corporation that the stock transfer books of

the stock transfer books of Rostone.  If, after the Effective Time, certificates
previously representing Shares are presented to the Surviving Corporation, they

Stockholders who previously held Rostone Preferred Stock until the aggregate
cumulative amount paid to such Stockholders under Section 2.3(b) and this
Section 2.3(c) equals $2,905,000.00; and then the balance, if any, to

If at any time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement to vest the Surviving
Corporation with full right, title and possession to all assets, property,
rights, privileges, powers, and franchises of either Oneida or Rostone, the
officers of such corporations are fully authorized in the name of their
corporation or otherwise to take, and shall take, all such lawful and necessary
action. In addition, Rostone shall cooperate to take all necessary actions to
ensure the transfer and/or continued validity of all permits, licenses and
authorizations necessary to the lawful operations of Rostone's facilities.

          2.5  Taxes.

          (a)  If any portion of the consideration payable hereunder upon the
Merger is to be paid to a Person other than the holder in whose name the
certificate formerly representing Shares surrendered in exchange therefor is
registered, it shall be a condition of such exchange that the certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the Person requesting such exchange shall pay to Rostone any transfer
or other taxes required by reason of the payment of the consideration payable
hereunder upon the Merger to a person other than the registered holder of the
certificate surrendered, or shall establish to the satisfaction of the Surviving
Corporation that such taxes have been paid or are not applicable.

such jurisdictions being every jurisdiction in which the nature of its business

instrument or violate any provision of any law, order, judgment, decree,
restriction or ruling of any governmental authority to which Rostone is a party
or by which any of its property is bound, which would, individually or in the
aggregate, have a Seller Material Adverse Effect or prevent the consummation of
the transactions contemplated hereby; or (iii) result in the creation of any
Lien upon the Shares or any of the assets of Rostone or the loss of any license
permit, grant of authority or other contractual right with respect thereto,
which would, individually or in the aggregate, have a Seller Material Adverse
Effect.

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

               (i) Schedule 3.1(h)(i) hereto sets forth a true and complete list
          of each lease of personal property to which Rostone is a party or by
          which it or any of its respective assets are bound which provides for
          payments in excess of $20,000 over the committed term of such lease or
          series of related leases (collectively, the "PERSONAL PROPERTY

          copy of each of the Personal Property Leases.

               (ii) Schedule 3.1(h)(ii) hereto sets forth a true and complete

          during the remainder of their term (including for these purposes any
          series of agreements with any Person or Affiliated group of Persons
          which in the aggregate require payments in excess of $50,000). Except
          as set forth on Schedule 3.1(h)(ii) hereto, Rostone is not a party to
          or bound by any Contract which limits or restricts it from competing
          in any line of business or carrying on or expanding the nature or

          has performed in all material respects, or is now performing in all
          material respects, its obligations under, and is not in default (and
          would not by the lapse of time or the giving of notice or both be in
          default) under, or in breach or violation of, nor has it received
          notice of any asserted claim of a default by Rostone under, or a
          breach or violation by Rostone of, any of the Personal Property Leases
          or Contracts, which failure of performance, default, breach or
          violation would, individually or in the aggregate, have a Seller
          Material Adverse Effect.

              (iv) Except as set forth in the Schedule 3.1(h) or as reflected
          on the Unaudited November 30, 1995 balance sheet of Rostone, Rostone
          has no liabilities or obligations to any present or former Affiliate
          of Rostone.

          (i)  Patents, Trademarks and Trade Names.  Rostone owns, or has
               ------------------------------------                       
licensed or otherwise has the right to use, all patents, registered trademarks,
trade names and registered copyrights (including those set forth on Schedule
3.1(i) hereto) necessary to the conduct of its business as currently conducted,
subject to such exceptions which would not, individually or in the aggregate,
have a Seller Material Adverse Effect.  Except as set forth on Schedule 3.1(i)
hereto, Rostone does not own or have any licenses with respect to any patents,
registered trademarks, tradenames and registered copyrights.  Subject to such
claims and other matters as would not, individually or in the aggregate, have a
Seller Material Adverse Effect, except as set forth on Schedule 3.1(i), no
claims are currently being asserted by any Person to the use of any such patent,
trademark, trade name or copyright or challenging or questioning the validity or
effectiveness of any such license or agreement; and the use of such patents,
trademarks, trade names and copyrights by Rostone and the Subsidiary does not
infringe on the rights of any Person.

          (j)  Litigation. Except as set forth on Schedule 3.1(j), there is no
               -----------                                                      
action, suit, investigation, claim or proceeding at law or in equity by or
before any arbitrator, court, governmental instrumentality or other agency
pending or, to the knowledge of Rostone, threatened, against Rostone, or any of
its assets, and to Rostone's knowledge, no event has occurred or circumstances
exist that could give rise to or serve as a basis for the commencement of any
such proceeding.  Without limiting the generality of the foregoing, there are no
liabilities of Rostone of any nature relating to the Linda S. Hart matters.

          (k)  Compliance with Laws.  Rostone is in compliance in all respects
               ---------------------                                           
with all laws, statutes, rules, regulations, ordinances, decrees and orders of
any federal, state, local or foreign governmental authority, any court or any
arbitrator ("LAWS") applicable to it or to the conduct of its business, except
where the failure to so comply would not, individually or in the aggregate, have
a Seller Material Adverse Effect.  Rostone is not charged with or, to the
knowledge of Rostone, has been threatened with any charge concerning or is under
any investigation with respect to, any violation of any provision of any Law,
except for such violations which would not, individually or in the aggregate,
have a Seller Material Adverse Effect.  Rostone is not in violation of or in
default under, and to the knowledge of Rostone, since December 31, 1990 no event
has occurred which, with the lapse of time or the giving of notice or both,
would result in the violation of or default under, the terms of any judgment,
decree, order, injunction or writ of any court or other governmental authority,
except for such violations or defaults which would not, individually or in the
aggregate, have a Seller Material Adverse Effect.

          (l)  Taxes. Rostone has filed when due all tax returns that it was
               ------                                                         
required to file, and has paid all taxes shown thereon as owing, except where
the failure to file such tax returns or to pay such taxes would not,
individually or in the aggregate, have a Seller Material Adverse Effect.  Except
as set forth on Schedule 3.1(l), none of the tax returns filed by, on behalf of
or with respect to Rostone is currently the subject of audit.  Tax returns have
been closed through March 1992.  Rostone has not waived any statute of
limitations in respect of taxes or agreed to any extension of time with respect
to a tax assessment or deficiency with respect to any tax return.  Rostone is
not party to any tax allocation or tax sharing agreement, and since December 31,
1990, Rostone has not been a member of an affiliated group (an "AFFILIATED

1986, as amended (the "CODE"), filing consolidated federal income tax returns
other than CGII ("CGII").

          (m)  Title to Property.  Rostone has good and marketable title to all
               ------------------                                               
of its properties and assets (including those set forth on Schedule 3.1(m)),
real, personal, mixed, tangible and intangible which are material to the conduct
of its business as it is currently conducted, free and clear of all Liens except
(a) Liens referred to in the notes to the Financial Statements, (b) Liens for
current taxes not yet due and payable, (c) such Liens and imperfections of
title, if any, as are not substantial in character, amount or extent and do not
materially impair the use or occupancy of such property or assets or the
business operations of Rostone, (d) Liens arising by operation of law without
the knowledge of Rostone (e) those properties and assets in which Rostone has
only a leasehold interest as indicated by an asterisk on Schedule 3.1(m) (each

title or interest would not, individually or in the aggregate, have a Seller
Material Adverse Effect.

          (n)  Insurance.  Schedule 3.1(n) hereto sets forth a true and
               ----------                                               
complete list of all material insurance policies or binders currently insuring
the property, assets or business liabilities of Rostone.  Rostone has delivered
or made available to the Purchaser summaries of such current policies and
binders.  All such current policies or binders are in full force and effect and
no premiums due and payable thereon are delinquent.  There are no pending
material claims against such insurance by Rostone.

          (o)  Licenses.  Rostone currently has, and Schedule 3.1(o) sets
               ---------

franchises and other authorizations of any federal, state, local or foreign
governmental authority ("LICENSES") required for the operation of its business
and the use and ownership or leasing of its properties and assets, as currently
operated, used, owned or leased, except where the loss, expiration, invalidity
or failure to have such Licenses would not, individually or in the aggregate,
have a Seller Material Adverse Effect.  All of such Licenses are valid, in full
force and effect and in good standing, except where the failure to be so would
not, individually or in the aggregate, have a Seller Material Adverse Effect.
There is no proceeding pending or, to the knowledge of Rostone, threatened, that
disputes the validity of any such License or that is likely to result in the

                                      15
<PAGE>
 
revocation, cancellation or suspension, or any adverse modification of, any such
License.  Rostone is, and at all times since December 31, 1990, has been, in
full compliance with all terms and requirements of each License, except where
the failure to do so would not, individually or in the aggregate, have a Seller
Material Adverse Effect.  No such License is limited, voided or otherwise
impaired by the transactions hereby contemplated and no action is necessary in
relation to maintaining the full force and effect of any License in connection
with the transactions hereby contemplated.

          severance pay, bonus or benefit arrangement, insurance or
          hospitalization program and any other fringe benefit arrangements,
          including, without limitation, any "employee benefit plan" (within the

          of 1974, as amended ("ERISA")) under which employees of Rostone are
          eligible to participate or derive a benefit (collectively, the
          "PLANS").

               (ii) Except as set forth on Schedule 3.1(p) hereto, each Plan, to
          the extent applicable, is and has been since December 31, 1990 in
          compliance in all material respects with the relevant provisions of
          ERISA and the Code. Except as set forth on Schedule 3.1(p) hereto,
          each Plan which is intended to meet the qualification requirements of
          Section 401(a) of the Code has been determined by the Internal Revenue
          Service to be so qualified and Rostone knows of no facts or
          circumstances which are likely to adversely affect the qualified
          status of any Plan.

               (iii) Except as set forth on Schedule 3.1(p) hereto, Rostone does

          and Rostone has not incurred any withdrawal liability, or suffered a
          "complete withdrawal" or a "partial withdrawal" with respect to a

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

Adverse Effect, (i) all handling, manufacturing, processing, distribution, use,
treatment, storage, transport and disposal of hazardous substances and non-

<PAGE>
 
Environmental Law; (iii) all permits, exemptions and other authorizations
required under applicable Environmental Laws for use of the property and the
operation of the business thereon have been obtained, are being complied with,
and all fees and assessments in association therewith have been timely paid and,

required in order to continue operation of the business; and (iv) with respect
to the disposal of any Hazardous Substance generated on or removed from any
property, Rostone has received no notice of an administrative proceeding,
violation, citation, administrative or consent order, lawsuit, action, claim,
demand or decree which alleges any violation of any applicable Environmental
Law, and has no knowledge that such disposal or removal has been conducted
without compliance with any applicable Environmental Law.

          "ENVIRONMENTAL LAW" means any federal, state or local law, regulation
or code, or any order, decree, judgment or injunction issued, promulgated,
approved or entered thereunder, relating to the condition of the air, ground,
surface water or soil or pollution of the environment or the protection of

"Pollutant or Contaminant," as such terms are defined in 40 C.F.R. (S) 300.5,
including any substance the presence of which requires investigation, removal,

          (r)  Labor Matters .  There are no controversies pending or, to the
               --------------                                                
knowledge of Rostone, threatened, between Rostone and any of its respective
employees, which controversies would, individually or in the aggregate, have a
Seller Material Adverse Effect.  Except as disclosed in Schedule 3.1(h), Rostone
is a not party to any collective bargaining agreement or other labor union
contract applicable to persons employed by it, nor, to the knowledge of Rostone,
are there any activities or proceedings of any labor union to organize any such
employees.  There is no strike or lockout or material slowdown or work stoppage
pending or, to the knowledge of Rostone, threatened, by or with respect to the
employees of Rostone or the Subsidiary.  Labor relations are satisfactory.

          (s)  Personal Property.  The equipment and fixtures owned by Rostone

wear and tear excepted,

                                      17
<PAGE>
 
and are adequate for the uses to which they are being put in the ordinary course
of Rostone's business. All the personal property owned by Rostone constitute, in
the reasonable business judgment of Rostone, all of the tangible personal
property necessary for the operation of the business of Rostone as it is
currently operated (other than such personal property as may be leased by
Rostone and other than those items, if any, the failure of which to own or lease
would not, individually or in the aggregate, have a Seller Material Adverse
Effect).

          (t)  Real Property.
               -------------- 

               (i) Schedule 3.1(t) hereto sets forth a true list of all real
          property owned by Rostone ("OWNED REAL PROPERTY") and of all real
          property leased by Rostone, clearly indicating which is which ("LEASED
          REAL PROPERTY" and, together with the Owned Real Property, "REAL
          PROPERTY").

               (ii) Except as set forth on Schedule 3.1(t) hereto, (A) Rostone

          not currently zoned to permit the conduct of the business of Rostone
          thereon as it is currently being conducted and (B) to the knowledge of
          Rostone, there are no notes or notices of any material violation of
          any material applicable Law noted in or issued by any governmental
          authority against or affecting any of the Real Property.

               (iii) Schedule 3.1(t) hereto sets forth a true and complete list
          of all of the leases relating to the Leased Real Property
          (collectively, the "REAL PROPERTY LEASES"). Rostone has delivered or
          made available to the Purchaser true and complete copies of the Real
          Property Leases. Each of the Real Property Leases is in full force and
          effect. Since December 31, 1994, Rostone has not received any written
          notice from any lessor under any of the Real Property Leases asserting
          that Rostone is in default thereunder and Rostone has no knowledge
          that it is in default thereunder. Rostone enjoys in all material
          respects peaceful and undisturbed possession under each of the Real
          Property Leases.

other agreements between Rostone and Society Capital Corporation have been
terminated and Rostone has no further obligations thereunder or under any

               -----------------                                             
record books and other records of Rostone, all of which have been made available
to Purchaser, are complete and correct and have been maintained in accordance
with sound business practices, including the maintenance of adequate system of
internal controls.  The minute books of Rostone contain accurate and complete
records of all meetings held of, and corporate action taken by, the
stockholders, Board of Directors, and committees of the Boards of Directors of
Rostone, and no meeting of any such stockholders, Board of Directors, or
committee has been held for which minutes have not been prepared and are not
contained in such minute books.

          (w) Accounts Receivable.   All accounts receivable of Rostone that
              -------------------                                           
are reflected on the November 30, 1995 balance sheet or on the accounting
records of Rostone as of the Closing Date (collectively, the "ACCOUNTS
RECEIVABLE") represent or will represent valid obligations arising from sales
actually made or services actually performed in the ordinary course of Rostone's
business.

          (x) Inventory.   All inventory of Rostone, whether or not reflected
               ---------                                                      
in the November 30, 1995 balance sheet, consists of a quality and quantity
usable and salable in the ordinary course of business, except for obsolete items
and items of below-standard quality, all of which have been written off or
written down to net realizable value in the November 30, 1995 balance sheet or
on the accounting records of Rostone as of the Closing Date, as the case may be.
All inventories not written off have been priced at the lower of cost or market
on the last in, first out basis.  The quantities of each item of inventory
(whether raw materials, work-in-process, or finished goods) are not excessive,
but are reasonable in the present circumstances of Rostone.

          (y)  Disclosure. 
               ----------- 

               (i) No representation or warranty of Rostone in this Agreement
          and no statement in any Schedule hereto omits to state a material fact
          necessary to make the statements herein or therein, in light of the
          circumstances in which they were made, not misleading.

               (ii) There is no fact known to Rostone that has specific
          application to Rostone (other than general economic or industry
          conditions) and that materially adversely affects or, as far as
          Rostone can reasonably foresee, materially threatens, the assets,
          business, prospects, financial condition, or results of operations of
          Rostone that has not been set forth in this Agreement or in the
          Schedules thereto.

               (iii) When considered cumulatively, the following items and
          liabilities do not and would not reasonably be expected to, have a
          Seller Material Adverse Effect: all items and liabilities that would
          be disclosed under any particular

                                      19
<PAGE>
 
          provision of this Section 3.1 but for the fact that Rostone deemed
          them to be "immaterial," or determined that they would not have a
          Seller Material Adverse Effect, or otherwise were not required to be
          disclosed because of their relative immateriality under any particular
          provision of this Section 3.1.


          (z)  Schedule 3.1(z) sets forth a true and complete list of all
obligations and liabilities, whether contingent or otherwise, of Rostone, (i)
for borrowed money (whether or not the recourse of the lender is to the whole of
Rostone's assets or only a portion thereof), (ii) evidenced by bonds, notes,
debentures or similar instruments or letters of credit, (iii) for the payment of
money for obligations under a lease that is required to be capitalized for
financial reporting purposes under GAAP (including Statement of Financial
Accounting Standards No. 13 of the Financial Accounting Standards Board as in
effect on the date of this Agreement), (iv) all liabilities of the nature set
forth in (i)-(iii) above that Rostone has guaranteed or that is otherwise its
legal liability, and (v) any and all deferrals, renewals, refinancings,
refundings, amendments, modifications or supplements to, any liability of the
kind described in any of the preceding clauses (i) through (iv), whether or not
between or among the same parties (collectively, "INDEBTEDNESS").  Except as set
forth on Schedule 3.1(z), Rostone has no Indebtedness.

          3.2  Representations and Warranties of the Purchaser. The Purchaser
               ------------------------------------------------

equitable principles relating to enforceability.

          (c)  No Conflict.  Neither the execution and delivery of this
               ------------

               --------------------------                                    
Affiliates nor any agent of any of them has authorized any person to act as
broker, finder, banker, consultant, intermediary or in any other similar
capacity (other than for the purpose of rendering a fairness opinion) which
would entitle such person to any investment banking, brokerage, finder's or
similar fee in connection with the transactions contemplated by this Agreement.

          (e) Litigation.  There is no action, suit, investigation, claim or
               -----------                                                    
proceeding at law or in equity by or before any arbitrator, court, governmental
instrumentality or other agency pending or, to the knowledge of the Purchaser,
threatened, against the Purchaser or any of its assets, properties or rights
which questions or challenges the validity of this Agreement or any action taken

the transactions contemplated hereby or which would, if adversely determined,
have a Purchaser Material Adverse Effect.

               ---------------------                                        
material respects with all material Laws applicable to it or to the conduct of
its business, except where the failure to so comply would not, individually or
in the aggregate, have a Purchaser Material Adverse Effect.

          (g)  Taxes.  The Purchaser has filed when due all tax returns that it
               ------                                                           
was required to file, and has paid all taxes shown thereon as owing, except

          6.1  Survival of Representations and Warranties.  Except as provided

          6.2 Indemnification by Rostone.
              --------------------------- 

          (a) Subject to Sections 6.1, 6.4(c) and 6.6 hereof, from and
after the Closing, Rostone shall indemnify and hold harmless the Purchaser, its
Affiliates, successors and assigns, and the officers, directors and shareholders
of each of them, from and against all damages, claims, losses, deficiencies,
liabilities and expenses (including reasonable accountants' and attorneys' fees)
of any kind or nature (collectively "DAMAGES") incurred thereby or caused
thereto, based on, arising out of, resulting from or relating to:

               (i) any breach of any of the representations or warranties made
by Rostone in this Agreement or any other Closing Document other than those, if
any, of which the Purchaser had actual knowledge at the time of Closing;

               (ii) any breach or violation of or failure to fully perform any
covenant, agreement or obligation of Rostone in this Agreement or any of the
other Closing Documents other than those, if any, of which the Purchaser had
actual knowledge at the time of the Closing; and

               (iii) any action, suit or claim by any third party for any
brokerage, finder's, agent's or similar fees or commissions in connection with
the transactions contemplated hereby insofar as such actions are alleged to be
based on arrangements or contacts made by or with Rostone or any of its
Affiliates (except the Purchaser).

          (b) Subject to Section 6.4(c)(ii) hereof, from and after the Closing,
Rostone shall indemnify and hold the Purchaser harmless against, and will pay to
the Purchaser, or its successors and assigns, the full amount of, (i) any
Rostone Debt in excess of $11,700,000 and (ii) any costs the Surviving
Corporation shall be required by any Environmental Law to pay in connection with
the remediation of environmental contamination that the Phase II Environmental
Site Assessment, dated December 22, 1995, prepared by ATEC for Reunion Resources
Company relating to the property at 2450 Sagamore Parkway South, Lafayette,
Indiana, suggests may exist in the ground water at such property. For purposes
of clause (ii) above, remediation shall not include the further Phase II
investigation costs necessary to further delineate the nature and extent of any
such contamination, but shall include the costs to develop a remediation plan
(if remediation is required by any Environmental Law), to obtain the necessary
governmental consents to the implementation of such remediation plan, and to
implement such plan.

          6.3  Indemnification by the Purchaser.  Subject to Sections 6.1 and
               ---------------------------------                              
6.6 hereof, from and after the Closing, the Purchaser shall indemnify and hold

relating to:

                                      24
<PAGE>
 
               (a) any breach of any of the representations or warranties made
by the Purchaser in this Agreement or any of the other Closing Documents other
than those, if any, of which Rostone had actual knowledge at the time of the
Closing;

               (b) any breach or violation of or failure to fully perform any
covenant, of the Purchaser in this Agreement or any of the other Closing
Documents other than those, if any, of which Rostone had actual knowledge at the
time of the Closing;

              (c) any liability of or claim against Rostone based on occurrences
after the Closing; or

              (d) any action, suit or claim by any third party for any
brokerage, finder's, agent's or similar fees or commissions in connection with
the transactions contemplated hereby insofar as such actions are alleged to be
based on arrangements or contacts made by, to or with the Purchaser or any of
its Affiliates (except Rostone).

          6.4  Notice and Payment of Claims.
               ----------------------------- 
               (a) Whenever any claim shall arise for indemnification
hereunder, the party entitled to indemnification under this Article VI (the
"INDEMNIFIED PARTY") shall notify the party liable for such indemnification
including, in the case of Rostone after the Effective Time, the Stockholders
(the "INDEMNIFYING PARTY") within a reasonable period of time after becoming
aware of, and shall provide to the Indemnifying Party as soon as practicable
thereafter all information and documentation necessary to support and verify,
any Damages that the Indemnified Party shall have determined have given or could
reasonably be expected to give rise to a claim for indemnification hereunder,
and the Indemnifying Party shall be given access to all books and records in the
possession or under the control of the Indemnified Party which the Indemnifying
Party reasonably determines to be related to such claim; provided, that, the
                                                         --------- -----
failure or delay in so notifying the Indemnifying Party shall not relieve the
Indemnifying Party of its obligations to indemnify pursuant to the terms of this
Agreement.

               (b) Subject to Section 6.4(c) hereof, all claims for indemnity
under this Article VI shall be paid by the Indemnifying Party on demand in
immediately available funds in U.S. dollars after such claim and the liability
for Damages thereunder shall be deemed to be finally determined.  A claim for
indemnification and the liability for Damages thereunder shall be deemed
"finally determined" for purposes of this Article VI when the parties have so
determined by mutual agreement or, if disputed, when a final non-appealable
order of a court of competent jurisdiction has been entered.

               (c) Notwithstanding any other term or provision of this
Agreement to the contrary, (i) Rostone shall not be liable for Damages arising
in connection with its

                                      25
<PAGE>
 
indemnification obligations under Section 6.2(a) hereof until such Damages shall
exceed $100,000 in the aggregate (and then only to the extent of such excess),
and (ii) Rostone's maximum cumulative liability for indemnification hereunder
shall not exceed the amount equal to the sum of the Merger Consideration and the
Preferred Consideration payable hereunder and the Purchaser's sole recourse
against Rostone (but not against CGII as set forth in the attached "Guaranty and
Subordination") for indemnification under this Agreement shall be by offset
against any Merger Consideration and Preferred Consideration that has not yet
been paid to the Stockholders pursuant to the terms of this Agreement. Rostone,
on behalf of itself and the Stockholders, hereby authorizes the Purchaser to
make any such offsets to which it is entitled hereunder.

          6.5  Matters Involving Third Parties.
               -------------------------------- 

               (a) If any third party shall commence an action, suit or claim
against any Indemnified Party with respect to any matter (a "THIRD PARTY CLAIM")
which may give rise to a claim for indemnification against any Indemnifying
Party under this Article VI, the Indemnified Party shall notify the Indemnifying
Party thereof in writing as soon as practicable.

               (b) The Indemnifying Party shall have the right to defend the
Indemnified Party against the Third Party Claim with counsel of its choice that
is reasonably acceptable to Indemnified Party, so long as (i) the Indemnifying
Party shall notify the Indemnified Party in writing (within 10 days after its
receipt of notice of the Third Party Claim) that it will indemnify the
Indemnified Party from and against any Damages the Indemnified Party may suffer
arising out of the Third Party Claim and (ii) the Indemnifying Party diligently
conducts the defense of the Third Party Claim.

               (c) So long as the Indemnifying Party is conducting the defense
of the Third Party Claim in accordance with Section 6.5(b) hereof, (i) the
Indemnified Party may retain separate co-counsel, at its sole cost and expense,
and participate in the defense of the Third Party Claim, (ii) the Indemnified
Party shall not consent to the entry of any judgment or enter into any
settlement with respect to the Third Party Claim without the prior consent of
the Indemnifying Party, (iii) the Indemnified Party shall cooperate within
reason with such defense and (iv) the Indemnifying Party shall not consent to
the entry of any judgment or enter into any settlement with respect to the Third
Party Claim without the prior written consent of the Indemnified Party, which
consent shall not be unreasonably withheld or delayed. Should the Indemnified
Party withhold consent under clause (iv) above in respect of a judgment or
settlement involving only the payment of money by the Indemnifying Party, the
Indemnifying Party shall have the right, upon notice to the Indemnified Party
within seven days of receipt of the Indemnified Party's denial of consent, to
pay to the Indemnified Party the full amount of such judgment or settlement,
including all interest, costs or other charges relating thereto, and shall pay
all attorneys' fees incurred to such date for which the Indemnifying Party is
obligated 

                                      26
<PAGE>
 
under this Agreement, at which time the Indemnifying Party's rights and
obligations with respect to the Third Party Claim shall cease.

          6.6  Mitigation of Damages.  If any event shall occur which would
               ----------------------                                       
otherwise entitle either party to assert a claim for indemnification hereunder,
no Damages shall be deemed to have been sustained by such party to the extent of
(a) any tax savings actually realized by such party with respect thereto or (b)
any net proceeds received by such party from any insurance policy with respect
thereto.

          6.7  Other Remedies.  The foregoing indemnification provisions of
               ---------------                                              
this Article VI are in addition to, and not in derogation of, any statutory,
equitable or common law remedy either party hereto may have for any breach of
any representation, warranty, covenant or agreement contained in this Agreement.

          7.1  Expenses.  All fees, commissions and other expenses incurred by
               ---------
