Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        ------------------------------------------------------------------------
        Securities of the Issuer.
        -------------------------

     The Trust and Comcast are parties to the following agreements summarized
below.

     Board Representation Agreement. Pursuant to the Board Representation
Agreement, the Trust has the right to require Comcast, to the extent permitted
under applicable law, to take steps to cause a Scripps Trust designee (the
"Initial Designee") reasonably acceptable to Comcast to be proposed for election
to the Board of Directors of Comcast. The Initial Designee will be so proposed
for election (if permitted under applicable law) at the earlier of (i) the first
meeting of Comcast's Board following

                                        5

   6



the consummation of the Merger, if there then exists a vacancy on the Comcast
Board or the Comcast Board has the power to create new directorships, or (ii) if
there then exists no such vacancy or the Comcast Board does not have such power,
at the first meeting of stockholders of Comcast following the consummation of
the Merger. The number of Scripps Trust designees will be increased to two
individuals if at any time directors are nominated the product of (i) the number
of directors then constituting the Comcast Board (not including any director
positions held by a Scripps Trust designee) and (ii) the fraction representing
the percentage of outstanding Comcast common stock represented by the Comcast
common stock held by the Scripps Trust for not less than one year is equal to or
greater than 1.75. Comcast will be required to recommend to its stockholders the
election of such designee(s), solicit proxies from its stockholders for such
election and take all other action reasonably necessary to cause such election.
Pursuant to the Board Representation Agreement, Sural Corporation, the
controlling stockholder of Comcast, has agreed to vote in favor of the election
of any Scripps Trust designee. If any Scripps Trust designee ceases to serve on
the Comcast Board of Directors prior to the expiration of such designee's
scheduled term, Comcast must take all actions reasonably necessary to cause the
vacancy to be filled by a replacement Scripps Trust designee. Unless the Scripps
Trust elects to terminate its rights under the Board Representation Agreement
voluntarily, its rights will terminate on the earlier to occur of (i) the date
on which the

                                        6

   7



Scripps Trust ceases to own at least 50% of the shares of Comcast Special Common
Stock acquired by the Scripps Trust in the Merger and (ii) the date of the
fourth annual meeting of the Comcast Board of Directors following the
consummation of the Merger. In addition, the Board Representation Agreement will
require the Scripps Trust, for a period of two years following the consummation
of the Merger, to vote in favor of certain amendments to Comcast's Articles of
Incorporation. The Scripps Trust also has the right under the Board
Representation Agreement to designate from time to time an observer to attend
Comcast Board meetings in lieu of designating a person to serve on Comcast's
Board.

     Registration Rights Agreement. Pursuant to the Registration Rights
Agreement, Comcast has certain obligations to register under the Securities Act
the shares of Comcast Special Common Stock issued to the Scripps Trust in the
Merger (the "Registrable Shares"). On not more than three occasions after the
consummation of the Merger, the Scripps Trust may demand that Comcast file a
registration statement under the Securities Act (a "Demand Registration"),
covering such number of Registrable Shares (which shall have a fair market value
of at least $100 million) as shall be specified in such demand. Comcast will not
be obligated to effect a Demand Registration within 12 months after the
effective date of a previous Demand Registration, and Comcast will have the
right to postpone for up to 150 days any Demand Registration if Comcast believes
it would be detrimental or disadvantageous to Comcast or its stockholders to
file such registration statement. Comcast cannot exercise its right to

                                        7

   8



postpone a Demand Registration more than once during any twelve-month period. In
addition, subject to certain terms, limitations and conditions contained in the
Registration Rights Agreement, the Scripps Trust will have the right to include
Registrable Shares in any registration statement filed by Comcast in respect of
a primary or secondary offering of Comcast Special Common Stock (other than on
Form S-4 or Form S-8 or a registration statement filed pursuant to Rule 415
under the Securities Act).

     The Registration Rights Agreement prohibits the Scripps Trust from
disposing of any of its shares of Comcast capital stock for 15 days prior to and
120 days following the effective date of any underwritten offering, unless the
managing underwriters of the offering agree otherwise. Comcast is prohibited
from publicly selling (except pursuant to benefit plans and registrations on
Form S-4) any Comcast Special Common Stock (or securities convertible into such
stock) during the 15- day period prior to, and the 90-day period following, the
effective date of an underwritten public offering which is a Demand
Registration. In addition, Comcast will be obligated to use its reasonable
efforts to cause all holders of 5% or more of any class of capital stock of
Comcast and all other holders of securities of Comcast purchased from Comcast
other than in a public offering to enter into agreements with Comcast with
restrictions similar to those in the preceding sentence.

     The Registration Rights Agreement provides that, in connection with a
Demand Registration, all expenses incurred by Comcast in complying with its
obligations, under the Registration

                                        8

   9



Rights Agreement, including, without limitation, all registration and filing
fees, fees and expenses of complying with securities and blue sky laws, listing
fees, printing expenses and fees and disbursements of accountants and counsel
for Comcast, will be paid by Comcast. The expenses paid by Comcast will not
include underwriting discounts and commissions attributable to shares of the
Scripps Trust.

     Pursuant to the Registration Rights Agreement, the Scripps Trust has agreed
to maintain until at least November 13, 1997, ownership of such number of shares
of Comcast Special Common Stock issued to it in the Merger as represents at
least 50% of the total consideration paid in the Merger. The Scripps Trust has
also agreed not to sell in the open market any of the Trust's Comcast Shares in
any period (not to exceed 10 trading days in any calendar month) in which,
following notice by Comcast to the Scripps Trust, Comcast proposes to repurchase
its shares pursuant to a repurchase program referred to in the Merger 
Agreement. Such repurchase program is to terminate no later than six month


after November 13, 1996.

                         BOARD REPRESENTATION AGREEMENT
 
     This Board Representation Agreement, dated as of             , 1996 (this
"Agreement") is by and among Comcast Corporation, a Pennsylvania corporation
("Acquiror"), Sural Corporation, a Delaware corporation, (the "Acquiror
Stockholder") and The Edward W. Scripps Trust (the "Trust").
 
     WHEREAS, the Acquiror Stockholder owns 1,845,037 shares of Acquiror's Class
A Common Stock, par value $1.00 per share, 5,315,772 shares of Acquiror's Class
A Special Common Stock, par value $1.00 per share, and 8,786,250 shares of
Acquiror's Class B Common Stock, par value $1.00 per share (all shares of such
stock now owned and which may hereafter be acquired by the Acquiror Stockholder
prior to the termination of this Agreement are referred to herein as the
"Acquiror Shares");
 
     WHEREAS, The E.W. Scripps Company, a Delaware corporation (the "Company"),
Scripps Howard, Inc., an Ohio corporation ("SHI") and wholly owned subsidiary of
the Company, and Acquiror have entered into a Merger Agreement dated October 28,
1995 (the "Merger Agreement"), which provides, among other things, that the
Company will merge with and into Acquiror (the "Merger") (this and other
capitalized terms used and not defined herein shall have the meanings given to
such terms in the Merger Agreement);
 
     WHEREAS, in connection with the Merger, the Trust will be entitled to
receive shares of Class A Special Common Stock, $1.00 par value per share, of
Acquiror (all such shares received by the Trust in the Merger, the "Trust
Shares"), and it is the desire of the Trust that it have the right to designate
certain persons for election as members of the board of directors of Acquiror
(the "Acquiror Board") following the consummation of the Merger;
 
     WHEREAS, pursuant to the Merger Agreement, Acquiror has agreed to cause
                    (the "Initial Trust Designee") to be elected to the Acquiror
Board as set forth herein following consummation of the Merger; and
 
     WHEREAS, it is a condition to the Company's and SHI's obligation to
consummate the Merger that the parties hereto enter into this Agreement;
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereto hereby agree as follows:
 
     1. Representation on Acquiror Board. To the extent permitted under
applicable law the Trust shall be entitled to representation on the Acquiror
Board as follows: the Initial Trust Designee shall be proposed for election to
the Acquiror Board either: (i) if following the consummation of the Merger there
are one or more vacancies on such Board or the members of such Board have the
power to create new directorships, at the first meeting of the Acquiror Board
following consummation of the Merger, at which the Initial Trust Designee shall
be elected or (ii) if there are no such vacancies or power to create new
directorships, at the first meeting of stockholders of Acquiror held after
consummation of the Merger. Following such election of the Initial Trust
Designee, in each instance in which individuals are nominated for election to
the Acquiror Board, Acquiror shall cause to be nominated for election to the
Acquiror Board that number of individuals designated by the Trust (the "Trust
Designee(s)") equal to the Appointment Number (as defined below) as of the date
of nomination, in the manner and subject to the conditions set forth in this
Section 1. Acquiror shall cause such Trust Designee(s) to be validly and timely
nominated for election to the Acquiror Board in the same manner as other
proposed directors are nominated, shall recommend to its stockholders the
election to the Acquiror Board of the Trust Designee(s) and shall not revoke or
qualify such recommendation. Acquiror shall use its best efforts to solicit from
its stockholders proxies in favor of the election of all the Trust Designee(s),
and shall take such other action as may be reasonably necessary to cause such
Trust Designee(s) to be so elected. If any Initial Trust Designee or Trust
Designee who serves on the Acquiror Board ceases, for any reason, to serve on
the Acquiror Board (other than as a result of the expiration of the specified
term of such Initial Trust Designee or Trust Designee), Acquiror shall take all
actions reasonably necessary to cause the vacancy to be filled, as soon as
practicable, by an individual designated by the Trust (a "Replacement Trust
Designee"), but in any event no later than the first meeting of the Acquiror
Board following cessation of
   12
 
service by such Designee. Each Initial Trust Designee, Trust Designee or
Replacement Trust Designee shall be reasonably acceptable to Acquiror and shall
be eligible to serve on the Acquiror Board under applicable law.
 
     For purposes hereof, "Appointment Number" means one, provided that the
Appointment Number shall be two if the product of (i) the total number of
directors constituting the Acquiror Board less the director position(s) held by
the designee(s) of the Trust and (ii) the quotient equal to (A) the number of
Long-term Shares held by the Trust at the time of nomination divided by (B) the
aggregate number of Acquiror Common Shares outstanding at such time on a fully
diluted basis shall be equal to or greater than 1.75. For purposes hereof, (i)
"Acquiror Common Shares" means shares of any class of common stock of Acquiror
and (ii) "Long-term Shares" means, as of any date, Acquiror Common Shares that
have been owned for not less than one year.
 
     From time to time upon the reasonable written request by Acquiror, the
Trust will provide Acquiror with an opinion of counsel (the "Opinion")
reasonably acceptable to Acquiror, which opinion shall state that the nomination
and appointment of a proposed Initial Trust Designee, Trust Designee or
Replacement Trust Designee, as the case may be, to the Acquiror Board is
permitted under applicable law. Except as provided in the following paragraph,
all obligations on the part of Acquiror and the Acquiror Stockholder under this
Agreement shall be suspended until the Opinion shall have been received by it.
 
     If the Trust shall not be permitted under applicable law to representation
on the Acquiror Board as described herein, or if the Trust should elect from
time to time observer status in lieu of a seat on the Board by written notice to
Acquiror, then to the extent permitted by law, the Trust shall for the period of
this Agreement be entitled to designate an observer who shall be entitled to
notice of and to attend all meetings of the Acquiror Board and to receive or
review, as the case may be, copies of all documents provided to members of the
Acquiror Board. Such observer shall enter into customary confidentiality
arrangements with the Company.
 
     2. Termination of Rights. The rights of the Trust under Section 1 hereof
shall terminate upon the earliest of (i) the date on which the Trust ceases to
own at least 50% of the Trust Shares (as equitably adjusted for stock splits,
combinations, dividends, corporate reorganizations and similar events), (ii) the
date on which the fourth annual meeting of Acquiror's Board is convened after
the date hereof, and (iii) the date on which the Trust elects to terminate
Section 1 of this Agreement by notice to the other parties hereto.
 
     3. Agreements of Acquiror Stockholder. To the extent permitted under
applicable law: the Acquiror Stockholder hereby agrees that, until such time as
the rights of the Trust terminate pursuant to Section 2 hereof, at any meeting
of the stockholders of Acquiror, however called, and in any action by consent of
the stockholders of Acquiror, for the election of directors, the Aquiror
Stockholder shall vote its Acquiror Shares in favor of the election to the
Acquiror Board of each Trust Designee and Replacement Trust Designee, as the
case may be.
 
     4. Representations and Warranties of Acquiror. Acquiror represents and
warrants to the Trust that:
 
          (a) Acquiror has all necessary corporate power and authority to
     execute and deliver this Agreement and to perform its obligations
     hereunder. The execution and delivery of this Agreement by Acquiror and the
     performance of its obligations hereunder have been duly and validly
     authorized by Acquiror, and no other proceedings on the part of Acquiror
     are necessary to authorize the execution and delivery of this Agreement or
     to perform such obligations except approval of Acquiror Board of a
     resolution increasing the size of Acquiror Board as provided herein and
     election of the designees of the Trust as provided herein. This Agreement
     has been duly and validly executed and delivered by Acquiror and, assuming
     the due authorization, execution and delivery hereof by each other party
     hereto, constitutes a legal, valid and binding obligation of Acquiror
     enforceable against Acquiror in accordance with its terms, except (i) as
     the same may be limited by applicable bankruptcy, insolvency, moratorium or
     similar laws of general application relating to or affecting creditors'
     rights, including without limitation, the effect of statutory or other laws
     regarding fraudulent conveyances and preferential transfers, (ii) for the
     limitations imposed by
 
                                        2
   13
 
     general principles of equity, and (iii) as the same may be limited under
     the Rules and Regulations regarding cross-ownership of cable television
     systems and television stations.
 
          (b) The execution and delivery of this Agreement by Acquiror do not,
     and the performance of this Agreement by Acquiror will not, (i) conflict
     with or violate the Articles of Incorporation or By-laws of Acquiror, (ii)
     except as described in Section 4(c), conflict with or violate any law,
     rule, regulation, order, judgment or decree applicable to Acquiror or by
     which any of Acquiror's property may be bound, or (iii) result in any
     breach of or constitute a default (or an event that with notice or lapse of
     time or both would become a default) under, or give to others any rights of
     termination, amendment, acceleration or cancellation of, or result in the
     creation of a lien or encumbrance on any of the Acquiror's properties
     pursuant to, any note, bond, mortgage, indenture, contract, agreement,
     lease, license, permit, franchise or other instrument or obligation to
     which Acquiror is a party or by which Acquiror or Acquiror's properties are
     bound or affected, except, in the case of clauses (ii) and (iii), for any
     such conflicts, violations, breaches, defaults or other occurrences which
     would not prevent or delay the performance by Acquiror of its obligations
     under this Agreement.
 
          (c) The execution and delivery of this Agreement by Acquiror do not,
     and the performance of this Agreement by Acquiror will not, require any
     consent, approval, authorization or permit of, or filing with or
     notification to, any federal, state, local or foreign regulatory body,
     except (i) where the failure to obtain such consents, approvals,
     authorizations or permits, or to make such filings or notifications, would
     not prevent or delay the performance by Acquiror of Acquiror's obligations
     under this Agreement, (ii) filings with the SEC under the Exchange Act and
     (iii) any waiver, consent or declaratory ruling by the FCC with respect to
     the Rules and Regulations regarding cross-ownership of cable television
     systems and television stations, to the extent that such Rules and
     Regulations may prohibit the performance of the Acquiror's obligations
     hereunder.
 
     5. Representations and Warranties of the Acquiror Stockholder. The Acquiror
Stockholder represents and warrants to the Trust as follows:
 
          (a) The Acquiror Stockholder has all necessary power and authority to
     execute and deliver this Agreement and to perform its obligations
     hereunder. The execution and delivery of this Agreement by the Acquiror
     Stockholder and the performance of the Acquiror Stockholder's obligations
     hereunder have been duly and validly authorized by the Acquiror
     Stockholder, and no other corporate proceedings on the part of the Acquiror
     Stockholder are necessary to authorize the execution and delivery of this
     Agreement or to perform such obligations. This Agreement has been duly and
     validly executed and delivered by the Acquiror Stockholder and, assuming
     the due authorization, execution and delivery hereof by each other party
     hereto, constitutes a legal, valid and binding obligation of the Acquiror
     Stockholder enforceable against the Acquiror Stockholder in accordance with
     its terms, except (i) as the same may be limited by applicable bankruptcy,
     insolvency, moratorium or similar laws of general application relating to
     or affecting creditors' rights, including without limitation, the effect of
     statutory or other laws regarding fraudulent conveyances and preferential
     transfers, (ii) for the limitations imposed by general principles of
     equity, and (iii) as the same may be limited under the Rules and
     Regulations regarding cross-ownership of cable television systems and
     television stations.
 
          (b) The execution and delivery of this Agreement by the Acquiror
     Stockholder do not, and the performance of this Agreement by the Acquiror
     Stockholder will not, (i) conflict with or violate the charter or by-laws
     of the Acquiror Stockholder, (ii) except as described in Section 5(c)
     below, conflict with or violate any law, rule, regulation, order, judgment
     or decree applicable to such Acquiror Stockholder or by which the Acquiror
     Shares are bound or affected, or (iii) result in any breach of or
     constitute a default (or an event that with notice or lapse of time or both
     would become a default) under, or give to others any rights of termination,
     amendment, acceleration or cancellation of, or result in the creation of a
     lien or encumbrance on any Acquiror Shares pursuant to, any note, bond,
     mortgage, indenture contract, agreement, lease, license, permit, franchise
     or other instrument or obligation to which the Acquiror Stockholder is a
     party or by which the Acquiror Shares are bound or affected, except, in the
     case of clauses (ii) and (iii), for any such conflicts, violations,
     breaches, defaults or other occurrences
 
                                        3
   14
 
     which would not prevent or delay the performance by the Acquiror
     Stockholder of its obligations under this Agreement.
 
          (c) The execution and delivery of this Agreement by the Acquiror
     Stockholder do not, and the performance of this Agreement by such Acquiror
     Stockholder will not, require any consent, approval, authorization or
     permit of, or filing with or notification to, any federal, state, local or
     foreign regulatory body, except (i) where the failure to obtain such
     consents, approvals, authorizations or permits, or to make such filings or
     notifications, would not prevent or delay the performance by the Acquiror
     Stockholder of its obligations under this Agreement, (ii) filings with the
     SEC under the Exchange Act, and (iii) any waiver, consent or declaratory
     ruling by the FCC with respect to the Rules and Regulations regarding
     cross-ownership of cable television systems and television stations, to the
     extent that such Rules and Regulations may prohibit the performance of the
     Acquiror Stockholder's obligations hereunder.
 
          (d) The Acquiror Stockholder is the owner of the Acquiror Shares free
     and clear of all security interests, liens, claims, pledges, options,
     rights of first refusal, agreements, limitations on voting rights, charges
     and other encumbrances of any nature whatsoever, except that 1,000,000
     shares of Class A Common Stock (the "Pledged Stock") are pledged to PNC
     Bank, N.A. pursuant to loan agreement dated April 23, 1992 and a collateral
     pledge agreement dated as of the same date (together, the "Loan
     Agreements"). PNC Bank, N.A. has the right to vote the Pledged Stock upon
     the occurrence of an event of default under the Loan Agreements. The
     Acquiror Stockholder has sole voting power with respect to the Acquiror
     Shares or has the power to direct the voting of the Acquiror Shares. The
     Acquiror Stockholder has not appointed or granted any proxy, which
     appointment or grant is still effective, with respect to the Acquiror
     Shares, other than pursuant to the Voting Agreement dated October 28, 1995
     among the parties hereto and the Company. The Acquiror Stockholder has sole
     voting power with respect to the Acquiror Shares, and the person executing
     this Agreement on behalf of the Acquiror Stockholder has the power to
     direct the voting of such Acquiror Shares.
 
     6. No Prohibition on Transfers. Nothing in this Agreement shall prevent the
Acquiror Stockholder from offering, selling, transferring, pledging or in any
other way disposing of or placing encumbrances upon the Acquiror Shares.
 
     7. Compensation, Expenses, Insurance. The Initial Trust Designee, Trust
Designees and Replacement Trust Designees serving on the Acquiror Board shall be
entitled to fees and other compensation, participation in option, stock or other
benefit plans for which directors are eligible, reimbursement of expenses, and
directors and officers liability insurance on an equal basis with other
non-employee members of the Acquiror Board.
 
     8. Voting for Permitted Amendments.
 
     (a) If from time to time any of the Permitted Amendments (as defined in the
Merger Agreement) is proposed for approval by the shareholders of Acquiror, the
Trust shall (i) be present, in person or represented by proxy, at the
stockholder meetings of Acquiror so that all shares of Acquiror Common Stock
beneficially owned by the Trust ("Trust Common Shares") shall be counted for the
purpose of determining the presence of a quorum at such meetings and (ii) vote
or cause to be voted, or consent with respect to, all Trust Common Shares in
favor of the approval of such Permitted Amendment. The Trust will not enter into
any agreement, commitment or understanding that limits, directs or restricts the
rights of the Trust to vote any Trust Common Shares so long as such Trust Shares
are owned by the Trust. The provisions of this subsection (a) shall terminate
two years from the date hereof.
 
     (b) In connection with any shareholder vote regarding the approval of a
Permitted Amendment, the Trust will not, singly or as part of a partnership,
limited partnership or other group (as such terms are used in Section 13(d)(3)
of the Exchange Act), directly or indirectly make, or in any way participate in
any "solicitation" of "proxies" to vote (as such terms are defined in Rule 14a-1
under the Exchange Act), solicit any consent or communicate with or seek to
advise or influence any person or entity with respect to the voting
 
                                        4
   15
 
of any Acquiror Common Securities or become a "participant" in any "election
contest" (as such terms are defined or used in Rule 14a-11 under the Exchange
Act) with respect to Acquiror.
 
     (c) The Trust acknowledges that it has reviewed Acquiror's Articles of
Incorporation and Proxy Statement dated May 19, 1995.
 
     9. Provisions Specifically Enforceable.
 
     (a) The obligations of Acquiror and the Acquiror Stockholder under this
Agreement are unique. Acquiror and the Acquiror Stockholder acknowledge that it
would be extremely difficult or impracticable to measure the resulting damages
caused by any breach of this Agreement. Acquiror and the Acquiror Stockholder
agree that, in the event of a breach of this Agreement by Acquiror or the
Acquiror Stockholder, the Trust, in addition to any other available rights or
remedies, shall be entitled to specific performance of the obligations of
Acquiror and the Acquiror Stockholder under this Agreement, and Aquiror and the
Acquiror Stockholder expressly agree that a remedy in damages will not be
adequate.
 
     (b) The remedies provided in this Section 8 are cumulative and are in
addition to any other remedies in law or equity which may be available to the
Trust. The election of one or more remedies shall not bar the use of other
remedies unless circumstances make the remedies incompatible.
 
     10. Choice of Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Pennsylvania regardless of the laws
that might otherwise govern under principles of conflicts of law applicable
hereto.
 
     11. Attorney's Fees. In any action to enforce the terms of this Agreement,
the prevailing party shall be entitled to recover its attorneys' fees and court
costs and other nonreimbursable litigation expenses, such as expert witness fees
and investigation expenses.
 
     12. Merger and Modification. This Agreement sets forth the entire agreement
between the parties relating to the subject matter hereof, and supersedes all
other oral or written provisions. This Agreement may be modified or terminated
only in a writing signed by all parties.
 
     13. Binding on Successors. This Agreement shall be binding upon Acquiror,
the Acquiror Stockholder and their respective successors and assigns.
 
     14. Rules of Construction. All section captions are for reference only, and
shall not be considered in construing this Agreement.
 
     15. Notices. All notices and other communications hereunder shall be in

                         REGISTRATION RIGHTS AGREEMENT
 
     THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of
                    , is made by and between Comcast Corporation, a Pennsylvania
corporation (the "Company"), and The Edward W. Scripps Trust (the "Trust").
 
     WHEREAS, this Agreement is being entered into pursuant to the Agreement and
Plan of Merger, dated as of October 28, 1995, among The E.W. Scripps Company,
Scripps Howard, Inc., and the Company (the "Merger Agreement");
 
     WHEREAS, it is intended by the Company and the Trust that this Agreement
shall become effective immediately upon the issuance of the Common Stock of the
Company to be issued pursuant to Article I of the Merger Agreement.
 
     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:
 
     1. Definitions. As used in this Agreement:
 
          a. "Commission" means the Securities and Exchange Commission.
 
          b. "Common Stock" means the Class A Special Common Stock, par value
     $1.00 per share, of the Company.
 
          c. "Person" means a natural person, a partnership, a corporation, an
     association, a joint stock company, a trust, an estate, a joint venture, an
     unincorporated organization or other entity or a governmental entity or any
     department, agency or political subdivision thereof.
 
          d. "Registrable Shares" means, at any particular time at which notice
     has been given pursuant to Section 2 or 3 hereunder, any of the following
     which are held by the Trust: (i) shares of Common Stock issued pursuant to
     the Merger; (ii) shares of Common Stock issued in lieu of cash dividends on
     other Registrable Shares pursuant to a dividend reinvestment plan adopted
     by the Company; (iii) shares of Common Stock then outstanding which were
     issued as, or upon the conversion or exercise of other securities issued
     as, a dividend or other distribution with respect to or in replacement of
     other Registrable Shares; (iv) shares of Common Stock then issuable upon
     conversion or exercise of other securities which were issued as a dividend
     or other distribution with respect to or in replacement of other
     Registrable Shares; and (v) any equity securities of the Company issued or
     issuable with respect to the securities referred to in clauses (i) through
     (iv) by way of a stock dividend or stock split or in connection with a
     combination of shares, recapitalization, merger, consolidation or other
     reorganization. For purposes of this Agreement, the Trust will be deemed to
     be a holder of Registrable Shares whenever it has the unqualified right to
     acquire such Registrable Shares (by conversion or otherwise, but
     disregarding any legal restrictions upon the exercise of such right),
     whether or not such acquisition has actually been effected.
 
          e. "Registration Expenses" has the meaning ascribed to it in Section 6
     of this Agreement.
 
          f. "Securities Act" means the Securities Act of 1933, as amended, and
     the rules and regulations thereunder.
 
     2. Demand Registrations.
 
     a. REQUESTS FOR REGISTRATION. From and after the date hereof, the Trust may
make a written request from time to time for registration under the Securities
Act of all or part of its Registrable Shares. Each such request will specify the
number of Registrable Shares to be registered and the intended method of
distribution thereof. All registrations requested pursuant to this Section 2(a)
are referred to herein as "Demand Registrations." Demand Registrations shall be
on any form for which the Company then qualifies and which
   18
 
counsel for the Company shall deem appropriate and available for the sale of the
Registrable Shares to be registered thereunder in accordance with the intended
method of distribution thereof; provided that the Company will include in any
short-form registration such additional customary information as the Trust may
reasonably request after consultation with the managing underwriter, in the case
of any underwritten public offering, or with the investment banker, in the case
of any non-underwritten offering, in order to facilitate the sale of such
securities; and provided further that the Company shall not be required to file
any such registration as a shelf registration under Rule 415 of the Securities
Act.
 
     b. REGISTRATIONS. A maximum of three Demand Registrations may be requested
by the Trust. A registration will not count as one of the Demand Registrations
requested by the Trust until it has become effective and unless either (i) the
Trust has registered and sold at least 90% of the Registrable Shares it requests
be included in such registration or (ii) the registration has remained effective
for at least 30 days. The Company will pay all Registration Expenses in
connection with any registration initiated as a Demand Registration requested
hereunder. Should a Demand Registration not become effective due to the failure
of the Trust to perform its obligations under this Agreement or the inability of
the Trust to reach agreement with the underwriters on price or other customary
terms for such transaction (provided that if the registration does not become
effective because of such inability then, on one occasion at the election of the
Trust, it shall not count as a Demand if the Trust pays the Company for all of
the Registration Expenses in respect thereof), or in the event the Trust
withdraws or does not pursue the request for the Demand Registration (in each of
the foregoing cases, provided that at such time the Company is in compliance in
all material respects with its obligations under this Agreement), then such
Demand Registration shall be deemed to have been effected. Each Demand
Registration must be in respect of Registrable Shares with a fair market value
in excess of $100,000,000.
 
     c. PREEMPTION. The Company will have the right to preempt any Demand
Registration with a primary registration by delivering written notice of such
intention to the Trust indicating that the Company has identified a specific
business need and use for the proceeds of the sale of such securities within
five business days after the Company has received from the Trust a request for
such Demand Registration. In the ensuing primary registration, the Trust will
have such piggyback registration rights as are set forth in Section 3 hereof.
Upon the Company's preemption of a requested Demand Registration, such requested
registration will not count as one of the Demand Registrations.
 
     d. PRIORITY ON DEMAND REGISTRATIONS. If a Demand Registration is an
underwritten public offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Shares and other
securities requested to be included in such offering would materially and
adversely affect the success of the offering, the Company will include in such
registration, prior to the inclusion of any securities which are not owned by
the Trust, the number of Registrable Shares requested to be included which in
the opinion of such underwriters can be sold without materially and adversely
affecting the success of the offering. Whenever a registration requested
pursuant to this Section is for an underwritten offering, only securities which
are to be distributed by the underwriters may be included in the registration.
 
     e. RESTRICTIONS ON REGISTRATIONS. The Company will not be obligated to
effect any Demand Registration within twelve months after the effective date of
a previous Demand Registration. The Company may postpone for up to 150 days the
filing or effectiveness of a registration statement for a Demand Registration if
the Company reasonably believes that it would be detrimental or otherwise
disadvantageous to the Company or its shareholders for such a registration
statement to be filed as expeditiously as possible; provided, however, the
Company cannot exercise its right to postpone the filing or effectiveness of a
registration statement for a Demand Registration more than once during any
12-month period.
 
     f. SELECTION OF UNDERWRITERS. The Trust shall have the right to select the
investment banker(s) and manager(s) to administer any public offering of equity
securities of the Company pursuant to a Demand Registration, subject to the
Company's approval, which approval shall not be unreasonably withheld.
 
                                        2
   19
 
     3. Piggyback Registrations.
 
     a. RIGHT TO PIGGYBACK. Subject to the remaining provisions of this Section
3, whenever the Company proposes to register its Common Stock under the
Securities Act for its own account (other than a registration on Form S-4 or S-8
or pursuant to Rule 415 or any substitute or successor form or rule,
respectively that may be adopted by the Commission) or for the account of any
holders of its Common Stock, the Company will give written notice to the Trust
of its intention to effect such a registration and will include in such
registration, on the same terms and conditions as apply to the Company's or such
holder's Common Stock, all Registrable Shares that the Trust requests be
included within 15 days after the receipt of the Company's notice (a "Piggyback
Registration"). The Company agrees that it will act in good faith in electing to
offer securities pursuant to Rule 415. The Company is required to include
Registrable Shares requested by the Trust in an unlimited number of Piggyback
Registrations. If the Company shall determine in its sole discretion not to
register or to delay the registration of such Common Stock, the Company may, at
its election, provide written notice of such determination to the Trust and (i)
in the case of a determination not to effect a registration, shall thereupon be
relieved of the obligation to register such Registrable Shares, and (ii) in the
case of a determination to delay a registration, shall thereupon be permitted to
delay registering any Registrable Shares for the same period as the delay in
respect of Common Stock being registered for the Company's own account.
 
     b. PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is an
underwritten primary offering on behalf of the Company, and the managing
underwriters for the Offering advise the Company in writing that in their
opinion the number of securities requested to be included in such registration
would materially and adversely affect the success of the offering, the Company
will include in such registration (i) first, the securities the Company proposes
to sell, and (ii) second, Registrable Shares and other securities such that the
included amount of each shall be in proportion to the amount of Registrable
Shares and other securities requested to be included in such registration.
 
     c. PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is an
underwritten secondary offering on behalf of holders of the Company's securities
other than holders of Registrable Shares, and the managing underwriters advise
the Company in writing that in their opinion the number of securities requested
to be included in such registration would materially and adversely affect the
success of the offering, the Company will include in such registration (i)
first, the securities included therein held by the holders other than the Trust,
and (ii) second, Registrable Shares and other securities such that the included
amount of each shall be in proportion to the amount of Registrable Shares and
other securities requested to be included in such registration.
 
     d. SELECTION OF UNDERWRITERS. If a Piggyback Registration is an
underwritten primary registration on behalf of the Company, and the Trust elects
to register and sell Registrable Shares in such registration, the Company will
have the right to select the investment banker(s) and manager(s) to administer
the offering.
 
     4. Holdback Agreements.
 
     a. The Trust agrees not to offer, sell, contract to sell or otherwise
dispose of any equity securities of the Company, or any securities convertible
into or exchangeable or exercisable for such securities, during the 15-day
period prior to, and the 120-day period beginning on the effective date of, any
underwritten registration (except as part of such underwritten registration),
unless the underwriters managing the registered public offering otherwise agree.
In order to ensure compliance with the provisions of this Section 4(a), the
Company hereby agrees to notify the Trust as to the status and proposed
effective date of any registration statement of the Company which is filed with
the Commission.
 
     b. The Company hereby agrees not to effect, except pursuant to employee
benefit plans and registrations on Form S-4, any public sale or distribution of
any securities of the same class as (or otherwise similar to) the Registrable
Shares, or any securities which, with notice, lapse of time and/or payment of
monies, are exchangeable or exercisable for or convertible into any such
securities during the 15-day period prior to, and during the 90-day period
commencing on, the effective date of a registration statement filed with the
Commission in connection with an underwritten offering effected pursuant to
Section 2 of this Agreement (except as part of such underwritten offering). The
Company agrees to use its reasonable efforts to cause each
 
                                        3
   20
 
holder of five percent or more of the outstanding shares of any equity security
(or any security convertible into or exchangeable or exercisable for any equity
security) of the Company, and each holder of any equity security (or any
security convertible into or exchangeable or exercisable for any equity
security) of the Company purchased from the Company at any time other than in a
public offering, to enter into a similar agreement with the Company.
 
     5. Registration Procedures. Whenever the Trust has requested that any
Registrable Shares be registered pursuant to this Agreement, the Company will
use its reasonable best efforts to effect the registration of such Registrable
Shares in accordance with the intended method of disposition thereof, and
pursuant thereto the Company will as expeditiously as possible:
 
          a. Prepare and file with the Commission a registration statement with
     respect to such Registrable Shares and cause such registration statement to
     become and remain effective for such period, not to exceed 60 days, as may
     be reasonably necessary to effect the sale of such securities and to
     include in any such registration statement all information which, in the
     opinion of counsel to the Trust and counsel to the Company, is reasonably
     required to be included therein under the Securities Act or which the
     managing underwriter, in the case of an underwritten public offering, or
     the investment banker, in the case of a non-underwritten offering,
     reasonably requests be included therein to facilitate the sale of such
     securities and which, in the opinion of counsel to the Company and counsel
     to the Trust, is customary and may appropriately be included therein under
     the Securities Act; provided, however, if (i) the effective date of any
     registration statement filed pursuant to a Demand Registration would
     otherwise be at least 45 calendar days, but fewer than 90 calendar days,
     after the end of the Company's fiscal year, and (ii) the Securities Act
     requires the Company to include audited financials as of the end of such
     fiscal year or the Securities Act permits the use of, and the Trust has
     requested that such registration statement include, audited financials as
     of the end of such fiscal year, the Company may delay the filing of such
     registration statement for such period as is reasonably necessary to
     include therein its audited financial statements for such fiscal year;
 
          b. Prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for a period of not less than 60 days and comply with
     the provisions of the Securities Act applicable to the Company with respect
     to the disposition of all securities covered by such registration statement
     during such period in accordance with the intended methods of disposition
     set forth in such registration statement;
 
          c. Furnish to the Trust and the underwriters such number of copies of
     such registration statement, each amendment and supplement thereto, the
     prospectus included in such registration statement (including each
     preliminary prospectus) as they may reasonably request in order to
     facilitate the disposition of the Registrable Shares;
 
          d. Use reasonable best efforts to register or qualify such Registrable
     Shares under such other securities or blue sky laws of such jurisdictions
     as the Trust reasonably requests and do any and all other acts and things
     which may be reasonably necessary or advisable to enable the Trust to
     consummate the disposition in such jurisdictions of the Registrable Shares
     (provided, however, that the Company will not be required to (i) qualify
     generally to do business in any jurisdiction where it would not otherwise
     be required to qualify but for this Section 4(d), (ii) subject itself to
     taxation in any such jurisdiction, or (iii) consent to general service of
     process in any such jurisdiction);
 
          e. Otherwise use its best efforts in connection with each registered
     offering of Registrable Shares hereunder to comply with all applicable
     rules and regulations of the Commission, as the same may hereafter be
     amended, including section 11(a) of the Securities Act and Rule 158
     thereunder.
 
          f. Use its best efforts to cause all such Registrable Shares to be
     listed on each securities exchange or market trading system on which
     similar securities issued by the Company are then listed;
 
                                        4
   21
 
          g. Enter into such customary agreements (including underwriting
     agreements that contain such representations and warranties by the Company
     and such other terms and provisions as are customarily contained in
     agreements of this type, including, but not limited to, indemnities to the
     effect and to the extent provided in Section 7, provisions for the delivery
     of officers' certificates, opinions of counsel and accountants' "comfort"
     letters and holdback arrangements) and take all such other actions as are
     reasonably required in order to expedite or facilitate the disposition of
     such Registrable Shares;
 
          h. Subject to confidentiality restrictions reasonably required by the
     Company, and subject to the reasonableness of the request therefor, make
     available at reasonable times for inspection by the Trust, any underwriter
     participating in any disposition pursuant to such registration statement,
     and any attorney, accountant or other agent retained by the Trust or any
     such underwriter, all pertinent financial and other records, pertinent
     corporate documents and properties of the Company, and cause the Company's
     officers, directors, employees and independent accountants to supply all
     information reasonably requested by the Trust or any such underwriter,
     attorney, accountant or agent in connection with such registration
     statement;
 
          i. Notify the Trust promptly after it shall receive notice thereof, of
     the time when such registration statement or amendment thereto has become
     effective or a prospectus or supplement to any prospectus forming a part of
     such registration statement has been filed;
 
          j. Notify the Trust of any request by the Commission for the amending
     or supplementing of such registration statement or prospectus or for
     supplemental information;
 
          k. Prepare and file with the Commission, promptly upon the request of
     the Trust, any amendments or supplements to such registration statement or
     prospectus which, in the opinion of counsel selected by the Trust and
     counsel to the Company, is reasonably required under the Securities Act or
     the rules and regulations thereunder in connection with the distribution of
     Registrable Shares by the Trust;
 
          l. Notify the Trust of the occurrence of any event during any time
     when a prospectus relating to such securities is required to be delivered
     under the Securities Act, as the result of which any such prospectus or any
     other prospectus as then in effect would include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances in which they were
     made, not misleading, and in such event, prepare and promptly file with the
     Commission and promptly notify the Trust of the filing of such amendment or
     supplement to such registration statement or prospectus as may be necessary
     to correct any such statements or omissions. The Trust agrees that, upon
     receipt of any notice from the Company of the occurrence of any event of
     the kind described in the preceding sentence, the Trust will forthwith
     discontinue the offer and sale of Registrable Shares pursuant to the
     registration statement covering such Registrable Shares until receipt by
     the Trust and the Underwriters of the copies of such supplemented or
     amended prospectus and, if so directed by the Company, the Trust will
     deliver to the Company all copies, other than permanent file copies then in
     the Trust's possession, of the most recent prospectus covering such
     Registrable Shares at the time of receipt of such notice. In the event the
     Company shall give such notice, the Company shall extend the 60 day-period
     during which such registration statement shall be maintained effective, as
     provided in Section 5(a) hereof, by the number of days during the period
     from and including the date of the giving of such notice to the date when
     the Company shall make available to the Trust such supplemented or amended
     prospectus;
 
          m. Advise the Trust, promptly after it shall receive notice or obtain
     knowledge thereof, of the issuance of any stop order by the Commission or
     any state authority or agency suspending the effectiveness of such
     registration statement or the initiation or threatening of any proceeding
     for such purpose and promptly use all reasonable efforts to prevent the
     issuance of any stop order or to obtain its withdrawal if such stop order
     should be issued;
 
          n. At the request of any underwriter in connection with an
     underwritten offering, furnish on the date or dates provided for in the
     underwriting agreement: (i) an opinion of counsel, addressed to the
     underwriters, covering such customary matters as such underwriters may
     reasonably request; and (ii) a
 
                                        5
   22
 
     comfort letter or letters from the independent certified public accountants
     of the Company addressed to the underwriters, covering such customary
     matters as such underwriters and sellers may reasonably request, in which
     letters such accountants shall state, without limiting the generality of
     the foregoing, that they are independent certified public accountants
     within the meaning of the Securities Act and that in the opinion of such
     accountants the financial statements and other financial data of the
     Company included in the registration statement, the prospectus, or any
     amendment or supplement thereto comply in all material respects with the
     applicable accounting requirements of the Commission;
 
          o. Subject to confidentiality restrictions reasonably required by the
     Company, at reasonable times and upon reasonable notice, and as necessary
     to permit a reasonable investigation with respect to the Company and its
     business in connection with the preparation and filing of such registration
     statement, make available for inspection by the Trust, by any managing
     underwriter or other underwriters participating in any disposition of
     Registrable Shares, and by any attorney, accountant or other agent,
     representative or advisor retained by the Trust or any such underwriters,
     all pertinent financial and other records and corporate documents of the
     Company; and to the extent reasonably required, cause the Company's
     officers, directors and employees to discuss pertinent aspects of the
     Company's business with the Trust and any such underwriter, accountant,
     agent, representative or advisor in connection with such registration
     statement;
 
          p. Permit the Trust, to the extent the Trust, in the judgment of its
     counsel, might be deemed to be a "control person" of the Company (within
     the meaning of Section 15 of the Securities Act or Section 20 of the
     Exchange Act), to participate in the preparation of such registration
     statement and include therein material, furnished to the Company in writing
     which, in the reasonable judgment of the Trust and its counsel, and counsel
     to the Company, is required to be included therein; and
 
          q. If any registration statement refers to the Trust by name or
     otherwise as the holder of any securities of the Company, and if the Trust
     reasonably believes it is or may be deemed to be a control person in
     relation to, or an Affiliate of, the Company, then the Trust shall have the
     right to require (i) insertion in such registration statement of language,
     in form and substance reasonably satisfactory to the Trust, to the effect
     that the ownership by the Trust of such securities is not to be construed
     as and is not intended to be a recommendation by the Trust of the
     investment quality of, or the relative merits and risks attendant to the
     purchase of, the Company's securities covered thereby, and that such
     ownership does not imply that the Trust will assist in meeting any future
     financial or operating requirements of the Company, or (ii) in the case
     where the reference to the Trust by name or otherwise is not required by
     the Securities Act or any similar federal or state statute then in effect,
     the deletion of the reference to the Trust.
 
          r. Cooperate in the marketing efforts of the underwriters and the
     Trust, including, without limitation, by making available, as reasonably
     requested by the underwriters and the Trust, the senior executive officers
     of the Company for attendance at, and active participation with the
     underwriters in, informational or so-called "roadshow" meetings with
     prospective purchasers of the Registrable Shares being offered, including
     meeting with groups of such purchasers or with individual purchasers,
     providing information and answering questions about the Company at such
     meetings, and traveling to locations in the United States and abroad as
     reasonably selected by the underwriters.
 
          6. Registration Expenses.
 
     All expenses of the Company incident to the Company's performance of or
compliance with this Agreement, including, without limitation, all registration
and filing fees, fees and expenses of compliance with securities or blue sky
laws, all fees and expenses associated with listing securities on exchanges or
Nasdaq, all fees and other expenses associated with filings with the NASD
(including, if required, the fees and expenses of any "qualified independent
underwriter" and its counsel) printing expenses, messenger and delivery
expenses, and fees and disbursements of counsel for the Company and its
independent certified public accountants (and the expenses of any special audits
or reviews performed by such accountants required by or incidental to such
performance and compliance), underwriters (excluding discounts and commissions
attributable to the
 
                                        6
   23
 
securities included in such registration) and other Persons retained by the
Company (all such expenses being herein called "Registration Expenses"), will be
borne by the Company. In addition, the Company will pay its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit or quarterly review, and the expense of any liability insurance obtained
by the Company.
 
     7. Indemnification and Contribution.
 
     a. The Company agrees to indemnify the Trust, its officers and trustees
against all losses, claims, damages, liabilities and expenses (including,
without limitation, reasonable attorneys' fees except as limited by Section
7(c)) caused by any untrue or alleged untrue statement of a material fact
contained in any registration statement, prospectus or preliminary prospectus
relating to the Registrable Shares or any amendment thereof or supplement
thereto or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as the same are caused by or contained in or based upon any
information furnished in writing to the Company by the Trust or any underwriter
expressly for use therein or by the Trust's or underwriter's failure to deliver
a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished the Trust or underwriter
with a sufficient number of copies of the same. In connection with an
underwritten offering, the Company will indemnify such underwriters, their
officers and directors and each Person who controls such underwriters (within
the meaning of the Securities Act) to the same extent as provided above with
respect to the indemnification of the Trust. In connection with an underwritten
offering, the underwriters shall be required to agree to indemnify the Trust,
its officers and trustees, and the Company, its officers and directors and each
Person who controls the Company (within the meaning of the Securities Act) to
the same extent as the Company agrees to indemnify such underwriters in this
Section 7(a), but only as to statements contained in or omitted from any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto in reliance upon written information furnished to
the Company by such underwriters for use in the preparation thereof. The
reimbursements required by this Section 7(a) will be made by periodic payments
during the course of the investigation or defense, as and when bills are
received or expenses incurred.
 
     b. In connection with any registration statement in which the Trust is
participating, it will furnish to the Company in writing such information,
questionnaires and affidavits as the Company reasonably requests for use in
connection with any such registration statement or prospectus and will indemnify
the Company, its directors and officers and each Person who controls the Company
(within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act) against any losses, claims, damages, liabilities and expenses
(including, without limitation, attorneys' fees except as limited by Section
7(c)) caused by any untrue or alleged untrue statement of a material fact
contained in any registration statement, prospectus or preliminary prospectus
relating to the Registrable Shares or any amendment thereof or supplement
thereto or any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading, but
only to the extent that such untrue statement or omission is contained in any
information or affidavit so furnished in writing by or on behalf of the Trust.
The Trust also agrees to indemnify and hold harmless any underwriters of the
Registrable Shares, their officers and directors and each person who controls
such underwriters on substantially the same basis as that of the indemnification
of the Company provided in this Section 7(b).
 
     c. Any Person entitled to indemnification hereunder will (i) give prompt
written notice to the indemnifying party of any claim with respect to which it
seeks indemnification and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party will not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent will not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim.
 
                                        7
   24
 
     d. The indemnification provided for under this Agreement will remain in
full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities. The Company also
agrees to make such provisions as are reasonably requested by any indemnified
party for contribution to such party in the event the Company's indemnification
is unavailable for any reason.
 
     e. If the indemnification from the indemnifying party as provided in this
Section 7 is unavailable or is otherwise insufficient to hold harmless any
Person entitled to indemnification in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then the indemnifying party shall,
to the fullest extent permitted by law, contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the Person entitled to
indemnification in connection with the actions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative fault of such indemnifying party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made, or relates to
information supplied by such indemnifying party, and the party's relative
intent, knowledge, access to information and opportunity to correct or prevent
such action. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include any legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding. The parties hereto agree that
it would not be just and equitable if contribution pursuant to this Section 7(e)
were determined by pro rata allocation or by any other method of allocation
which does not take account of the equitable considerations referred to in this
Section 7(e). No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.
 
     8. Compliance With Rule 144. At the request of the Trust, the Company will
(i) forthwith furnish a written statement of its compliance with the filing
requirements of the Commission as set forth in Rule 144 or any similar rules or
regulations hereafter adopted by the Commission as such may be amended from time
to time, (ii) make available to the public and the Trust such information, and
(iii) take such further actions as the Trust shall reasonably request as will
enable the Trust to be permitted to make sales pursuant to Rule 144 or such
similar rules and regulations. All sales of Registrable Shares by the Trust must
be effected in compliance with applicable law.
 
     9. Participation in Underwritten Registrations. The Trust may not
participate in any registration hereunder which is underwritten unless it (a)
agrees to sell Registrable Shares on the basis provided in any underwriting
arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements, (b) completes and executes all questionnaires, powers of
attorney, custody agreements, indemnities, underwriting agreements and other
documents required under the terms of such underwriting arrangements, and (c)
furnishes in writing to the Company such information regarding the Trust, the
plan of distribution of the Registrable Shares and other information as the
Company may from time to time reasonably request or as may be legally required
in connection with such registration. The Trust will have the right to select
the managing underwriters to administer any Demand Registration, subject to the
approval of the Company, which approval will not be unreasonably withheld.
 
     10. Prohibition on Transfer.
 
     (a) The Trust hereby agrees that it will not, during the period commencing
on the date hereof and ending one year after the date hereof, offer, pledge,
encumber, sell, contract to sell, sell any option or contract to purchase,
purchase any option to sell or otherwise dispose of, directly or indirectly, an
amount of Registrable Shares such that the total Registrable Shares owned by the
Trust at any time during such one-year period falls below the Continuity Amount.
For purposes hereof, "Continuity Amount" means the amount of shares of Common
Stock issued pursuant to the Merger representing 50% of the aggregate value of
the
 
                                        8
   25
 
consideration issued in the Merger (including, for this purpose, any shares of
Common Stock issued in the Merger, any payments to holders of Dissenting Shares
and any payments in lieu of fractional shares).
 
     (b) From time to time, if the Company intends to purchase shares of Common
Stock in the open market pursuant to the share repurchase program referred to in
Section 6.31 (the "Program") of the Merger Agreement, the Company may deliver a
notice (a "Black-Out Notice") to the Trust setting forth the period during which
the Company anticipates making such purchases (a "Black-Out Period"). The Trust
agrees that it will not sell any Registrable Shares in the open market during a
Black-Out Period. In order to be effective, the Company must deliver a Black-Out
Notice by facsimile to [ ] at [ ], to be confirmed by telephone at [ ] by no
later than 4:00 p.m. the day prior to the commencement of the Black-Out Period.
Each trading day within a Black-Out Period is referred to herein as a "Black- 
Out Day." In no event shall the Company cause more than 10 trading days in any 
one calendar month to be Black-Out Days. The Company will promptly inform the 
Trust of any early termination of a Black-Out Period. The Trust agrees to hold
information regarding Black-Out Periods in confidence. The Company represents
that the Program will be terminated no later than six months from the date
hereof.
 
     11. No Inconsistent Agreements. The Company will not hereafter enter into
any agreement with respect to its securities which is inconsistent with or
otherwise materially interferes with the rights granted to the Trust in this
Agreement.
 
     12. Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically, to recover
damages caused by reason of any breach of any provision of this Agreement, and
to exercise all other rights granted by law.
 
     13. Amendments and Waivers. Except as otherwise expressly provided herein,
the provisions of this Agreement may be amended or waived at any time only by
the written agreement of the Company and the Trust.
 
     14. Successors and Assigns. Except as otherwise expressly provided herein,
all covenants and agreements contained in this Agreement by or on behalf of any
of the parties hereto will bind and inure to the benefit of the respective
successors and assigns of the parties hereto, whether so expressed or not.
 
     15. Final Agreement. This Agreement constitutes the final agreement of the
parties concerning the matters referred to herein, and supersedes all prior
agreements and understandings.
 
     16. Severability. Whenever possible, each provision of this Agreement will
be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be prohibited by or invalid
under applicable law, such provision will be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of this
Agreement.
 
     17. Descriptive Headings. The descriptive headings of this Agreement are
inserted for convenience of reference only and do not constitute a part of and
shall not be utilized in interpreting this Agreement.
 
     18. Notices. Except as provided in Section 10(b), any notices required or
permitted to be sent hereunder shall be delivered personally or mailed,
certified mail, return receipt requested, or delivered by overnight courier
service to the following addresses, or such other addresses as shall be given by
notice delivered hereunder, and shall be deemed to have been given upon
