reaffirms all terms and conditions of all security or other collateral granted
to the Bank, and confirms that the indebtedness secured thereby includes,
without limitation, the Indebtedness.

7.   NO DEFENSES OF BORROWER. Borrower agrees that, as of this date, it has no
defenses against the obligations to pay any amounts under the Indebtedness.

8.   CONTINUING VALIDITY. Borrower understands and agrees that in modifying the

reason Bank cannot avail itself of the courts of the Commonwealth of
Massachusetts, then venue shall lie in Santa Clara County, California.

10.  COUNTERSIGNATURE. This Loan Modification Agreement shall become effective
only when it shall have been executed by Borrower and Bank (provided, however,
in no event shall this Loan Modification Agreement become effective until signed
by an officer of Bank in California).

     This Loan Modification Agreement is executed as a sealed instrument under
the laws of the Commonwealth of Massachusetts as of the date first written
above.

SECTION 2.02 Disclosure. All facts relating to the assets, business,
operations, financial condition and prospects (as such prospects relate to Emmis
and its Subsidiaries, not to business conditions in the radio or television
broadcast industries generally) of Emmis and its Subsidiaries necessary for a
reasonably prudent investor to make an investment decision with respect to the
acquisition of the Purchased Shares contemplated hereby have been disclosed to
Liberty. Neither this Agreement, nor any other agreement, document, certificate
or other written instrument delivered pursuant hereto, contains or will contain
any untrue statement of a material fact or omits or will omit to state a
material fact necessary to make the statements herein and therein, when taken
together, not misleading.

SECTION 2.03 Each of Emmis and its Subsidiaries (as defined in Section 8.11) has
been duly incorporated or organized, is validly existing as a corporation,
partnership or limited liability company in good standing under the laws of its
jurisdiction of incorporation or organization and has the corporate, partnership
or limited liability company power and authority to carry on its business as
described in the prospectus (the "PROSPECTUS") contained in the registration
statement on Form S-3 (file no. 333-88219) filed by Emmis (the "REGISTRATION
STATEMENT") and to own, lease and operate its properties, and each is duly
qualified and is in good standing as a foreign corporation, partnership or
limited liability company authorized to do business in each jurisdiction in
which the nature of its business or its ownership or leasing of property
requires such qualification, except where the failure to be so qualified would
not have a material adverse effect on the business, prospects, financial
condition or results of operations of Emmis and its Subsidiaries, taken as a
whole (a "MATERIAL ADVERSE EFFECT").

SECTION 2.04 The entities listed on Schedule I are the only Subsidiaries, direct
or indirect, of Emmis. All of the outstanding equity interests of each of Emmis'
Subsidiaries have been duly authorized and validly issued and are fully paid and
non-assessable and, except as set forth on Schedule I hereto, are owned by
Emmis, directly or indirectly through one or more Subsidiaries, free and clear
of any security interest, claim, lien, encumbrance, or adverse interest of any
nature (each, a "LIEN").

SECTION 2.05 There are no outstanding subscriptions, rights, warrants, options,
calls, convertible securities, commitments of sale or liens granted or issued by
Emmis or any of its Subsidiaries relating to or entitling any person to purchase
or otherwise to acquire any shares of the capital stock of Emmis or any of its
Subsidiaries, except as otherwise disclosed in the Registration Statement or
pursuant to Emmis' employee benefit plans.

more Subsidiaries, free and clear of any security interest, claim, lien,
encumbrance or adverse interest of any nature.

SECTION 2.08 The authorized and outstanding capital stock of Emmis conforms to
the first paragraph under the caption "Description of Capital Stock" in the
Prospectus and as to legal matters to the description thereof contained in the

respective charter, by-laws or equivalent organizational document or in default
in the performance of any obligation, agreement, covenant or condition contained
in any indenture, loan agreement, mortgage, lease or other agreement or
instrument to which Emmis or any of its Subsidiaries is a party or by which
Emmis or any of its Subsidiaries or their respective property is bound, except
for defaults that are not material to Emmis and its Subsidiaries, taken as a
whole.

SECTION 2.10 The execution, delivery and performance of this Agreement by Emmis,
the compliance by Emmis with all the provisions hereof and the consummation of
the transactions contemplated hereby will not (i) require any consent, approval,
authorization or other order (a "Governmental Consent") of, or qualification,
registration or filing (a "Governmental Filing") with, any court or governmental
body or agency (except such as may be required under the securities or Blue Sky
laws of the various states), (ii) conflict with or constitute a breach of any of
the terms or provisions of, or a default under, the charter or by-laws of Emmis
or any of its Subsidiaries or any indenture, loan agreement, mortgage, lease or
other agreement or instrument that is material to Emmis and its Subsidiaries,
taken as a whole, to which Emmis or any of its Subsidiaries is a party or by
which Emmis or any of its Subsidiaries or their respective property is bound,
(iii) violate or conflict with any applicable law or any rule, regulation,
judgment, order or decree of any court or any governmental body or agency having
jurisdiction over Emmis, any of its Subsidiaries or their respective property,
(iv) result in the imposition or creation of (or the obligation to create or
impose) a Lien under, any agreement or instrument to which Emmis or any of its
Subsidiaries is a party or by which Emmis or any of its Subsidiaries or their
respective property is bound or (v) result in the suspension, termination or

                                       8
<PAGE>   9
revocation of any Authorization (as defined below) of Emmis or any of its
Subsidiaries or any other impairment of the rights of the holder of any such
Authorization.

SECTION 2.11 There are no legal or governmental proceedings pending or
threatened to which Emmis or any of its Subsidiaries is or could be a party or
to which any of their respective property is or could be subject that are
required to be described in the Registration Statement or the Prospectus and are
not so described; nor are there any statutes, regulations, contracts or other
documents that are required to be described in the Registration Statement or the
Prospectus or to be filed as exhibits to the Registration Statement that are not
so described or filed as required.

SECTION 2.12 Neither Emmis nor any of its Subsidiaries has violated any foreign,
federal, state or local law or regulation relating to the protection of human
health and safety, the environment or hazardous or toxic substances or wastes,
pollutants or contaminants ("ENVIRONMENTAL LAWS"), any provisions of the
Employee Retirement Income Security Act of 1974, as amended, or any provisions
of the Foreign Corrupt Practices Act or the rules and regulations promulgated
thereunder, except for such violations which, singly or in the aggregate, would
not have a Material Adverse Effect.

SECTION 2.13 There are no costs or liabilities associated with Environmental
Laws (including, without limitation, any capital or operating expenditures
required for clean-up, closure of properties or compliance with Environmental
Laws or any Authorization, any related constraints on operating activities and
any potential liabilities to third parties) which would, singly or in the
aggregate, have a Material Adverse Effect.

SECTION 2.14 Each of Emmis and its Subsidiaries has such permits, licenses,
consents, exemptions, franchises, authorizations and other approvals (each, an
"AUTHORIZATION") of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and all
courts and other tribunals (each, a "Governmental Entity"), including, without
limitation, under any applicable Environmental Laws, as are necessary to own,
lease, license and operate its respective properties and to conduct its
business, except where the failure to have any such Authorization or to make any
such filing or notice would not, singly or in the aggregate, have a Material
Adverse Effect. Each such Authorization is valid and in full force and effect
and each of Emmis and its Subsidiaries is in compliance with all the terms and
conditions thereof and with the rules and regulations of the authorities and
governing bodies having jurisdiction with respect thereto; and no event has
occurred (including, without limitation, the receipt of any notice from any
authority or governing body) which allows or, after notice or lapse of

                                       9
<PAGE>   10

time or both, would allow, revocation, suspension or termination of any such
Authorization or results or, after notice or lapse of time or both, would result
in any other impairment of the rights of the holder of any such Authorization;
and such Authorizations contain no restrictions that are burdensome to Emmis or
any of its Subsidiaries; except where such failure to be valid and in full force
and effect or to be in compliance, the occurrence of any such event or the
presence of any such restriction would not, singly or in the aggregate, have a
Material Adverse Effect.

SECTION 2.15 This Agreement has been duly authorized, executed and delivered by
Emmis.

SECTION 2.16 Arthur Andersen LLP are independent public accountants with respect
to Emmis and its Subsidiaries as required by the Securities Act of 1933, as
amended (the "ACT").

SECTION 2.17 The consolidated financial statements included or incorporated by
reference in the Registration Statement and the Prospectus (and any amendment or
supplement thereto), together with related schedules and notes, present fairly
in all material respects the consolidated financial position, results of
operations and changes in financial position of Emmis and its Subsidiaries on
the basis stated therein at the respective dates or for the respective periods
to which they apply; such statements and related schedules and notes have been
prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods involved, except as disclosed
therein; the supporting schedules, if any, included in the Registration
Statement present fairly in all material respects in accordance with generally
accepted accounting principles the information required to be stated therein;
and the other financial and statistical information and data set forth in the
Registration Statement and the Prospectus (and any amendment or supplement
thereto) are, in all material respects, accurately presented and prepared on a
basis consistent with such financial statements and the books and records of
Emmis.

SECTION 2.18 Emmis is not and, after giving effect to the sale of the Purchased
Shares, will not be, an "investment company" as such term is defined in the
Investment Company Act of 1940, as amended.

SECTION 2.19 There are no contracts, agreements or understandings between Emmis
and any person granting such person the right to require Emmis to file a
registration statement under the Act with respect to any securities of Emmis.

SECTION 2.20 Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the

                                       10
<PAGE>   11

date of this Agreement), (i) there has not occurred any material adverse change
or any development involving a prospective material adverse change in the
condition, financial or otherwise, or the earnings, business, management or
operations of Emmis and its Subsidiaries, taken as a whole, (ii) there has not
been any material adverse change or any development involving a prospective
material adverse change in the capital stock or in the long-term debt of Emmis
or any of its Subsidiaries and (iii) neither Emmis nor any of its Subsidiaries
has incurred any material liability or obligation, direct or contingent.

SECTION 2.21 No consent or approval of the Federal Communications Commission
(the "FCC") is required under the Communications Act of 1934, as amended, and
the regulations promulgated thereunder (the "COMMUNICATIONS LAWS") for the
issuance and sale of the Purchased Shares. The execution, delivery and
performance of this Agreement in accordance with the terms hereof does not
violate the Communications Laws.

SECTION 2.22 The Subsidiaries of Emmis identified on Schedule II hereto (the
"LICENSE SUBSIDIARIES") hold all necessary authorizations, approvals, consents,
orders, licenses, certificates and permits issued by the FCC to own and operate
each of the respective radio or television broadcast stations (the "STATIONS")
as identified on Schedule II hereto (all such FCC authorizations, approvals,
consents, order, licenses, certificates and permits of the License Subsidiaries
collectively the "FCC LICENSES").

SECTION 2.23 Emmis and its Subsidiaries have good and marketable title in fee
simple to all real property and good and marketable title to all personal
property owned by them which is material to the business of Emmis and its
Subsidiaries, taken as a whole, in each case free and clear of all liens,
encumbrances and defects except such as do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of
such property by Emmis and its Subsidiaries; and any real property and buildings
held under lease by Emmis and its Subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as are not material and
do not interfere with the use made and proposed to be made of such property and
buildings by Emmis and its Subsidiaries.

SECTION 2.24 Emmis and its Subsidiaries own or possess, or can acquire on
reasonable terms, all patents, patent rights, licenses, inventions, copyrights,
know-how (including trade secrets and other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), trademarks,
service marks and trade names ("INTELLECTUAL PROPERTY") currently employed by
them in connection with the businesses now operated by them except where the
failure to own or possess or otherwise acquire such intellectual

                                       11
<PAGE>   12

property would not, singly or in the aggregate, have a Material Adverse Effect;
and neither Emmis nor any of its Subsidiaries has received any notice of
infringement of or conflict with asserted rights of others with respect to any
of such intellectual property which, singly or in the aggregate, if the subject
of an unfavorable decision, ruling or finding, would have a Material Adverse
Effect.

SECTION 2.25 Emmis and each of its Subsidiaries are insured by insurers of
recognized financial responsibility against such losses and risks and in such
amounts as are prudent and customary in the businesses in which they are
engaged; and neither Emmis nor any of its Subsidiaries (i) has received notice
from any insurer or agent of such insurer that substantial capital improvements
or other material expenditures will have to be made in order to continue such
insurance or (ii) has any reason to believe that it will not be able to renew
its existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers at a cost that would not have a Material
Adverse Effect.

SECTION 2.26 Except as disclosed or incorporated by reference in the Prospectus,
no relationship, direct or indirect, exists between or among Emmis or any of its
Subsidiaries on the one hand, and the directors, officers, shareholders,
customers or suppliers of Emmis or any of its Subsidiaries on the other hand,
which is required by the Act to be described in the Registration Statement or
the Prospectus which is not so described.

SECTION 2.27 There is no (i) significant unfair labor practice complaint,
grievance or arbitration proceeding pending or threatened against Emmis or any
of its Subsidiaries before the National Labor Relations Board or any state or
local labor relations board, (ii) strike, labor dispute, slowdown or stoppage
pending or threatened against Emmis or any of its Subsidiaries or (iii) union
representation question existing with respect to the employees of Emmis and its
Subsidiaries, except for such actions specified in clause (i), (ii) or (iii)
above, which, singly or in the aggregate, would not have a Material Adverse
Effect. To the best of Emmis' knowledge, no collective bargaining organizing
activities are taking place with respect to Emmis or any of its Subsidiaries.

SECTION 2.28 Emmis and each of its Subsidiaries maintain a system of internal
accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorizations; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is

                                       12
<PAGE>   13

compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.

SECTION 2.29 All material tax returns required to be filed by Emmis and each of
its Subsidiaries in any jurisdiction have been filed, other than those filings
being contested in good faith, and all material taxes, including withholding
taxes, penalties and interest, assessments, fees and other charges due pursuant
to such returns or pursuant to any assessment received by Emmis or any of its
Subsidiaries have been paid, other than those being contested in good faith and
for which adequate reserves have been provided.

SECTION 2.30 Emmis has reviewed its operations and the operations of its
Subsidiaries and any third parties with which Emmis or any of its Subsidiaries
has a material relationship to evaluate the extent to which the business or
operations of Emmis or any of its Subsidiaries will be affected by the Year 2000
Problem (as defined below). As a result of such review, Emmis has no reason to
believe, and does not believe, that the Year 2000 Problem will have a Material
Adverse Effect. The "YEAR 2000 PROBLEM" as used herein means any risk that the
computer hardware or software used in the receipt, transmission, storage,
retrieval, retransmission or other utilization of data or in the operation of
mechanical or electrical systems of any kind will not, in the case of dates or
time periods occurring after December 31, 1999, function at least as effectively
as in the case of dates or time periods occurring prior to January 1, 2000.

SECTION 2.31 No "nationally recognized statistical rating organization" as such
term is defined for purposes of Rule 436(g)(2) under the Act has indicated to
Emmis that it is considering (i) the downgrading, suspension or withdrawal of,
or any review for a possible change that does not indicate the direction of the
possible change in, any rating assigned to Emmis or any securities of Emmis or
(ii) any change in the outlook for any rating of Emmis or any securities of
Emmis.

SECTION 2.32 Any documents which at the date hereof are incorporated by
reference in the Registration Statement, the Prospectus or any amendment or
supplement thereto, or any preliminary prospectus (the "INCORPORATED DOCUMENTS")
were filed in a timely manner and, when they were filed (or, if any amendment
with respect to any such document was filed, when such amendment was filed),
conformed with the requirements of the Securities Exchange Act of 1934, as
amended (the "EXCHANGE ACT") and did not contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading.

SECTION 2.33 The Class A Common Stock is registered pursuant to Section 12(g) of
the Exchange Act and is listed on The Nasdaq National Market, and Emmis has
taken no action designed to, or likely to have the effect of, terminating the
registration of the Class A Common Stock under the Exchange Act or delisting the
Class A Common Stock from The Nasdaq National Market, nor has Emmis received any
notification that the Securities and Exchange Commission (the "COMMISSION") or
the National Association of Securities Dealers, Inc. ("NASD") is contemplating
terminating such registration or listing. Upon issuance to Liberty or its
permitted assignee under Section 9.05, the Purchased Shares shall be approved
for listing on The Nasdaq National Market.

                                   ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF LIBERTY

Liberty hereby represents and warrants to Emmis as follows:

SECTION 3.01 Authorization and Validity of Agreement . Liberty has all requisite
corporate power and authority to enter into this Agreement and to perform its
obligations hereunder and consummate the transactions contemplated hereby. The
execution, delivery and performance by Liberty of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of Liberty. This Agreement has
been duly executed and delivered by Liberty and is a valid and binding
obligation of Liberty, enforceable in accordance with its terms (except insofar
as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights
generally, or by principles governing the availability of equitable remedies).

SECTION 3.02 No Conflict with Instruments . Neither the execution or delivery of
this Agreement by Liberty, nor the purchase by Liberty of the Purchased Shares
pursuant hereto, (i) violates, conflicts in any material respect with, or
results in a material breach of any provision of, or constitutes a material
default (or an event which, with notice or lapse of time or both, would
constitute a material default) under, any of the terms, conditions or provisions
of (x) its Certificate of Incorporation or By-Laws, or (y) any material note,
bond, mortgage, indenture, lease, agreement or other instrument or obligation to
which Liberty is a party or to which it or any of its properties or assets may
be subject, (ii) results in a material violation of any material law applicable
to Liberty or (iii) violates any material judgment applicable to any of its
properties or assets, except, in the case of each of the clauses (i), (ii) and
(iii) above, for such violations, conflicts, breaches or defaults, which,

                                       14
<PAGE>   15

individually or in the aggregate, would not have any material adverse effect on
the ability of Liberty to perform its obligations hereunder.

SECTION 3.03 Brokers or Finders . No agent, broker, investment banker, financial
advisor or other person or entity is or will be entitled, by reason of any
agreement, act or statement by Liberty or any of its directors, officers or
employees, to any financial advisory, broker's, finder's or similar fee or
commission, to reimbursement of expenses or to indemnification or contribution
in connection with any of the transactions contemplated by this Agreement, and
Liberty agrees to indemnify and hold Emmis harmless from and against any and all
claims, liabilities or obligations with respect to any such fees, commissions,
expenses or claims for indemnification or contribution asserted by any person on
the basis of any act or statement made by Liberty or any of its directors,
officers or employees.

SECTION 3.04 Investment Purpose . Liberty is acquiring the Purchased Shares
solely for the purpose of investment and, except as provided in the Registration
Rights Agreement, not with a view to, or for offer or sale in connection with,
any distribution thereof in any transaction which would be in violation of the
securities laws of the United States of America or any state thereof. Liberty
understands that the certificate representing the Purchased Shares will contain
a legend stating in substance:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933 and such shares may not be sold or
         transferred unless such sale or transfer will be effected in accordance
         with the registration requirements of the Securities Act of 1933, as at
         that time amended, or in accordance with any exemption from the
         registration requirements of such Act, which may then be available
         thereto."

         RESTRICTIONS ON TRANSFER AND VOTING: The Amended and Restated Articles
         of Incorporation of the Corporation provide that (i) the Corporation
         shall not issue to or for the account of an Alien any share of capital
         stock of the Corporation if such issuance would cause the total capital
         stock of the Corporation held by or voted by Aliens to exceed, in
         violation of the Communications Act of 1934, as amended (the
         "Communications Act"), 25% of (A) the total capital stock of the
         Corporation outstanding at any time or (B) the total voting power of
         all shares of such capital stock outstanding and entitled to vote at
         any time; and (ii) the Corporation shall not permit the transfer on its
         books of any capital stock to any Alien that would result in the total
         capital stock of the Corporation held or voted

                                       15
<PAGE>   16

         by Aliens to exceed such 25% limits in violation of the Communications
         Act; and (iii) no Alien or Aliens, individually or collectively, shall
         be entitled to vote or direct or control the vote of more than 25% of
         (A) the total capital stock of the Corporation outstanding at any time,
         or (B) the total voting power of all shares of capital stock of the
         Corporation outstanding and entitled to vote at any time, if to do so
         would violate the Communications Act. The term "Alien" means (i) a
         person who is a citizen of a country other than the United States; (ii)
         an entity organized under the laws of a government other than the
         government of the United States or any state, territory, or possession
         of the United States; (iii) a government other than the government of
         the United States or any state, territory, or possession of the United
         States; or (iv) a representative of, or an individual or entity
         controlled by, any of the foregoing. The Amended and Restated Articles
         of Incorporation also provide that the Board of Directors of the
         Corporation shall have all powers necessary to implement the provisions
         of the Amended and Restated Articles of Incorporation regarding Alien
         ownership and to insure compliance with the Alien ownership
         restrictions of the Communications Act including, without limitation,
         the power to prohibit the transfer of any shares of capital stock of
         the Corporation to any Alien, the power to redeem shares of capital
         stock of the Corporation determined by the Board of Directors to be
         owned beneficially by an Alien or Aliens and the power to take or cause
         to be taken such other action as it deems appropriate to implement such
         restrictions.

                                   ARTICLE IV

Bylaws, (ii) reclassify the outstanding shares of its capital stock or make any
other changes in its capital structure or (iii) declare, set aside, pay or make

announcement or furnish any written statement to its employees or stockholders
generally concerning the transactions contemplated by this Agreement without the
consent of the other party (which consent shall not be unreasonably withheld),
except to the extent required by applicable law or the applicable requirements
of the New York Stock Exchange or the National Association of Securities

with timely compliance with such requirement, consult with the other party prior
to making the required release, announcement or statement).

Agreement and applicable law, each of the parties shall use its reasonable
efforts to take, or cause to be taken, all actions, and do, or cause to be done,
all things reasonably necessary, proper or advisable to consummate and make
effective the transactions contemplated by this Agreement as soon as reasonably
practicable, including such actions or things as either party hereto may

obligation to consummate such transactions specified in Article V to be fully
satisfied. Without limiting the generality of the foregoing, the parties shall
(and shall cause their respective Subsidiaries, and use their reasonable efforts
to cause their respective directors, officers, employees, agents, attorneys,
accountants and representatives, to) consult and fully cooperate with and
provide reasonable assistance to each other in obtaining all necessary consents,

amend, in any material respect any contract. Prior to making any application to
or filing with any Governmental Entity or other person or entity in connection
with this Agreement, each of Liberty and Emmis shall provide the other party
with drafts thereof and afford the other party a reasonable opportunity to

SECTION 7.03 Indemnification Procedures.
             --------------------------

(a)       Procedures for Indemnification of Third Party Claims.
          ----------------------------------------------------

          (i)   If a party entitled to indemnification under Section 7.02 (an
          "Indemnitee") shall receive notice or otherwise learn of the assertion
          by a person, company or other entity (including, without limitation,
          any Governmental Entity) (a "Person") who is not a party to this
          Agreement, of any claim or of the commencement or threat by any such
          Person of any action, suit, arbitration, inquiry, proceeding or
          investigation by or before any court or other Governmental Agency (a
          "Third Party Claim") with respect to which the other party may be
          obligated to provide indemnification pursuant to Section 7.02 (an
          "Indemnifying Party"), such Indemnitee shall give such Indemnifying
          Party written notice thereof promptly after becoming aware of such
          Third Party Claim and in no event later than the second anniversary of
          the Closing Date; provided that the failure of any Indemnitee to give
          notice or any delay in giving notice as provided in this Section
          7.03(a) shall not relieve the related Indemnifying Party of its
          obligations under this Article VII, except to the extent that such
          Indemnifying Party is prejudiced by such failure to give or delay in
          giving notice. Such notice shall describe the Third Party Claim in
          reasonable detail and, if ascertainable, shall indicate the amount
          (estimated if necessary) of the Loss that has been or may be sustained
          by such Indemnitee.

          (ii)  An Indemnifying Party may elect to defend or to seek to settle
          or compromise, at such Indemnifying Party's own expense and by such
          Indemnifying Party's own counsel, any Third Party Claim. Within 30
          days of the receipt of notice from an Indemnitee in accordance with
          Section 7.03(a)(i) (or sooner, if the nature of such Third Party Claim
          so requires), the Indemnifying Party shall notify the Indemnitee of
          its election whether the Indemnifying Party will assume responsibility
          for defending such Third Party Claim, which election shall specify any
          reservations or exceptions. If the Indemnifying Party assumes the
          defense of a Third Party Claim, the Indemnitee shall be kept
          reasonably informed with respect to, and shall have the right to
          employ separate counsel and to participate in (but not control) the
          defense, compromise or settlement thereof, but the fees and expenses
          of such separate counsel shall be the expense of such Indemnitee
          unless (x) the Indemnifying Party agrees in advance to pay such fees
          and expenses or (y) the Indemnitee shall have been advised by its
          counsel that there may be one or more legal defenses available to it
          which are different from or additional to those available to the
          Indemnifying Party, in which case the fees and expenses of such
          separate counsel shall be borne by the Indemnifying Party. If an
          Indemnifying Party elects

<PAGE>   24

          not to assume responsibility for defending a Third Party Claim, or
          fails to notify an Indemnitee of its election as provided in this
          Section 7.03(a)(ii), such Indemnitee may defend or seek to compromise
          or settle such Third Party Claim at the expense of the Indemnifying
          Party. Neither an Indemnifying Party nor an Indemnitee shall consent
          to entry of any judgment or enter into any settlement of any Third
          Party Claim which does not include as an unconditional term thereof
          the giving by the claimant or plaintiff to such Indemnitee, in the
          case of a consent or settlement by an Indemnifying Party, or the
          Indemnifying Party, in the case of a consent or settlement by the
          Indemnitee, of a written release from all liability in respect of such
          Third Party Claim.

          (iii) If an Indemnifying Party chooses to defend or to seek to
          compromise or settle any Third Party Claim, the related Indemnitee
          shall make available to such Indemnifying Party (in a manner that will
          not unreasonably interfere with the conduct of the Indemnitee's
          business) any personnel or any books, records or other documents
          within its control or which it otherwise has the ability to make
          available that are necessary or appropriate for such defense,
          settlement or compromise, and shall otherwise cooperate (in a manner
          that will not unreasonably interfere with the conduct of the
          Indemnitee's business) in the defense, settlement or compromise of
          such Third Party Claim.

          (iv)  Notwithstanding anything in this Section 7.03(a) to the
          contrary, (A) neither an Indemnifying Party nor an Indemnitee shall,
          without the written consent of the other party, settle or compromise
          or consent to the entry of any judgment with respect to any Action or
          Third Party Claim if the effect thereof is to admit any criminal
          liability by, or to permit any injunctive relief or other order
          providing non-monetary relief to be entered against, the other party
          and (B) neither an Indemnifying Party nor an Indemnitee may settle or
          compromise any claim without the consent of the other (which consent
          shall not be unreasonably withheld). Subject to clause (A) of this
          paragraph (iv), if an Indemnifying Party notifies the related
          Indemnitee in writing of such Indemnifying Party's desire to settle or
          compromise a Third Party Claim on the basis set forth in such notice
          (provided that such settlement or compromise includes as an
          unconditional term thereof the giving by the claimant or plaintiff of
          a written release of the Indemnitee from all liability in respect
          thereof) and the Indemnitee shall notify the Indemnifying Party in
          writing that such Indemnitee declines to accept any such settlement or
          compromise, such Indemnitee may continue to contest such Third Party
          Claim, free of any participation by such Indemnifying Party, at such
          Indemnitee's sole expense. In such event, the obligation of such
          Indemnifying Party to such Indemnitee with

<PAGE>   25

          respect to such Third Party Claim shall be equal to (1) the costs and
          expenses of such Indemnitee prior to the date such Indemnifying Party
          notifies such Indemnitee of the offer to settle or compromise (to the
          extent such costs and expenses are otherwise indemnifiable hereunder)
          plus (2) the lesser of (x) the amount of any offer of settlement or
          compromise which such Indemnitee declined to accept and (y) the actual
          out-of-pocket amount such Indemnitee is obligated to pay subsequent to
          such date as a result of such Indemnitee's continuing to contest such
          Third Party Claim.

          (v)   In the event of payment by an Indemnifying Party to any
          Indemnitee in connection with any Third Party Claim, such Indemnifying
          Party shall be subrogated to and shall stand in the place of such
          Indemnitee as to any events or circumstances in respect of which such
          Indemnitee may have any right or claim relating to such Third Party
          Claim against any claimant or plaintiff asserting such Third Party
          Claim or against any other Person. Such Indemnitee shall cooperate
          with such Indemnifying Party in a reasonable manner, and at the cost
          and expense of such Indemnifying Party, in prosecuting any subrogated
          right or claim.

(b)      Other Procedures for Indemnification.
         ------------------------------------

          (i)   Any claim on account of a Loss which does not result from a
          Third Party Claim shall be asserted by written notice given by the
          Indemnitee to the related Indemnifying Party, in no event later than
          the second anniversary of the Closing Date. Such Indemnifying Party
          shall have a period of 30 days after the receipt of such notice within
          which to respond thereto. If such Indemnifying Party does not respond
          within such 30 day period, such Indemnifying Party shall be deemed to
          have refused to accept responsibility to make payment. If such
          Indemnifying Party does not respond within such 30 day period or
          rejects such claim in whole or in part, such Indemnitee shall be free
          to pursue such remedies as may be available to such party under
          applicable law.

          (ii)  If the amount of any Liability shall, at any time subsequent to
          the payment required by this Agreement, be reduced by recovery,
          settlement or otherwise, the amount of such reduction, less any
          expenses incurred in connection therewith, shall promptly be repaid by
          the Indemnitee to the Indemnifying Party.

SECTION 7.04 Remedies Cumulative . Subject to the limitations set forth in
Section 7.04 hereof, the remedies provided in this Article VII shall be
cumulative, and the remedies provided in this Article VII shall not preclude
assertion by an Indemnitee of any other rights or

<PAGE>   26

the seeking of any and all other remedies against any Indemnifying Party.

                             ARTICLE VIII
                    POST-CLOSING COVENANTS

SECTION 8.01 Ownership Attribution. Emmis and Liberty intend that the ownership
of the Purchased Shares by Liberty or any FCC Affiliate (as defined below) shall
not cause (i) the direct or indirect ownership, now or in the future, by Liberty
or an FCC Affiliate of any broadcast station, newspaper, cable television system
or multipoint distribution system (each, a "Media Property") to be attributed to
Emmis under applicable rules (the "FCC Attribution Rules") of the Federal
Communications Commission (the "FCC"); or (ii) the direct or indirect ownership,
now or in the future, by Emmis or an FCC Affiliate of any Media Property to be
attributed to Liberty under the FCC Attribution Rules, if in either case such
attribution of ownership would result in the violation of any applicable
multiple ownership or cross-ownership rules of the FCC (the "FCC Ownership
Rules"). If at any time the ownership by Liberty or an FCC Affiliate of
Purchased Shares causes attribution to Emmis or to Liberty as set forth in (i)
or (ii), respectively ("Ownership Attribution"), that would result in a
violation of any applicable FCC Ownership Rule, then:

<PAGE>   27

         (a) Liberty shall, and shall cause each FCC Affiliate to, promptly
execute and deliver a proxy to a designee selected by Liberty entitling such
designee to exercise the voting power of the Purchased Shares for the election
of directors of Emmis. Each proxy shall pertain to such percentage of the
Purchased Shares and otherwise be in form and substance sufficient to eliminate
such Ownership Attribution to the extent a proxy is then acceptable to the FCC
for such purpose. Each such proxy granted by Liberty or an FCC Affiliate shall
remain in effect until (i) ownership of the Purchased Shares subject to the
proxy is transferred to a person or entity other than Liberty or an FCC
Affiliate; or (ii) such time as the grantor of the proxy may vote its Purchased
Shares without resulting in the violation of any FCC Ownership Rule.

         (b) If the granting of a proxy as contemplated by foregoing Subsection
(a) is not then acceptable to the FCC as a means to eliminate such Ownership
Attribution, Liberty agrees, and shall cause each FCC Affiliate that holds any
Purchased Shares to agree, to exchange all or such portion of the Purchased
Shares as required by the FCC to eliminate such Ownership Attribution for an
equal number of duly authorized, validly issued, fully paid and non-assessable
shares of non-voting common stock of Emmis having the same rights and privileges
as the Purchased Shares other than the right to vote except as required by
applicable law. Liberty, at its option, may elect for any reason to exchange all
or any portion of the Purchased Shares for an equal number of duly authorized,
validly issued, fully paid and non-assessable shares of such non-voting common
stock of Emmis at any time after Emmis' Articles of Incorporation have been
amended to create such non-voting common stock, which amendment Emmis shall use
its reasonable efforts to effect as soon as practicable. Each such share of
non-voting common stock shall be exchangeable into one share of Class A Common
Stock (i) upon the transfer of such share of non-voting common stock to a person
or entity other than Liberty or an FCC Affiliate; or (ii) at such time as the
holder of such share could vote its Purchased Shares without resulting in the
violation of any FCC Ownership Rule.

         (c) In the event that the actions contemplated by foregoing Subsections
(a) and (b) are not acceptable to the FCC as a means to eliminate such Ownership
Attribution, Emmis and Liberty agree, and Liberty shall cause each of its FCC
Affiliates that own any of the Purchased Shares to agree, to promptly take such
other action as reasonably necessary and appropriate to eliminate such Ownership
Attribution in a manner acceptable to the FCC.

         The term "FCC Affiliate" shall mean, when used with respect to Liberty
or Emmis, respectively, any person or entity whose ownership of any Media
Property would be attributable to Liberty or Emmis, respectively, under the FCC
Attribution Rules, or any person or entity

<PAGE>   28

that is an affiliate of Liberty or Emmis, respectively.

         Emmis and Liberty intend that, as between themselves, neither Emmis,
Liberty nor any of their respective FCC Affiliates shall be restricted or
prohibited from acquiring, owning or operating any Media Property in any market.
Emmis and Liberty, however, recognize that ownership by Emmis, Liberty or their
respective FCC Affiliates of Media Properties in the same market could result in
the violation of the FCC Ownership Rules by reason of Ownership Attribution.
Emmis and Liberty agree, as between themselves and on behalf of their respective
FCC Affiliates, that the sole action that any of them will be required to take
to avoid such a violation shall be compliance by Liberty and its FCC Affiliates
with the terms of this Section 8.01. Without limiting the generality of the
foregoing, in the event that Emmis in good faith gives written notice to Liberty
that Emmis intends to acquire a Media Property in a market which, by reason of
Ownership Attribution, would result in the violation of any FCC Ownership Rule,
Liberty shall, and shall cause each FCC Affiliate to, promptly take such action
as provided in foregoing subsections (a), (b) or (c) to prospectively prevent
such violation by eliminating such Ownership Attribution as soon as practicable
to permit Emmis to consummate the intended acquisition without unreasonable
delay by reason of such prospective violation.

SECTION 8.02 Lockup. Liberty covenants and agrees that Liberty shall not, and
shall cause each of its affiliates (including, but not limited to, controlled
Subsidiaries) not to, sell or otherwise transfer any of the Purchased Shares for
a period of twelve (12) months commencing on the Closing Date; provided that (i)
Liberty may transfer all or any portion of the Purchased Shares to one or more
controlled Subsidiaries of Liberty, (ii) Liberty may transfer up to one-third of
the Purchased Shares to one or more affiliates of Liberty that are not
controlled Subsidiaries, and (iii) Liberty, any controlled Subsidiary and any
affiliate of Liberty holding Purchased Shares may pledge any Purchased Shares to
secure bona fide indebtedness owed to an unrelated party or in support of
hedging transactions, puts, calls, exchangeable securities, collars and
derivative transactions.

SECTION 8.03 Preemptive Rights.

<PAGE>   29

         (a) If at any time that Liberty and its Affiliates own at least One
Million Four Hundred Thousand (1,400,000) of the Purchased Shares (as adjusted
from time to time to account for any stock dividend, stock split or reverse
stock split) Emmis issues any New Securities except as provided in Subsection
(c) below, Liberty and any Permitted Assignee shall each have the right, but not
the obligation, to purchase such New Securities up to an amount sufficient to
permit it to maintain its percentage common equity interest in Emmis (based on
the Number of Common Shares Outstanding existing immediately prior to the
issuance of the New Securities). The "Number of Common Shares Outstanding" as of
any time means the sum of (i) the number of shares of Emmis common stock which
then are actually issued and outstanding, plus (ii) the total number of
additional shares of common stock which would then be issued and outstanding if
it were assumed that all outstanding Qualifying Rights, if any, were then duly
exercised in full (whether or not then exercisable). If Emmis desires to issue
New Securities, it will first give written notice (an "Issuance Notice") thereof
to Liberty and each Permitted Assignee stating the number of New Securities
proposed to be issued, the total consideration to be received by Emmis upon sale
of the New Securities and any other material terms of the transaction. Within
three (3) days after the receipt of such notice, Liberty and each Permitted
Assignee may exercise its rights under this Section 8.03 by giving written
notice to that effect to Emmis. Failure to give such notice within that three
(3) days period will constitute a waiver of the rights granted by this Section
8.03 as to the particular issuance of New Securities specified in the Issuance
Notice.

         (b) The per share purchase price to be paid upon exercise of the rights
granted under this Section 8.03 will be equal to the lowest per share
consideration at which the New Securities are offered or proposed to be offered
by Emmis to any purchasers of New Securities before any underwriter's discount.
The consideration for which New Securities are offered or proposed to be offered
will be determined as follows:

             (i) in case of the proposed issuance of New Securities for cash,
the consideration to be received by Emmis will be the amount of cash for
which the New Securities are proposed to be issued and

<PAGE>   30

             (ii) in case of the proposed issuance of New Securities in whole or
in part for consideration other than cash, the value of the consideration to be
received by Emmis other than cash will be the Fair Market Value of that
consideration.

         (c) The provisions of this Section 8.01 will not apply to shares of
common stock of Emmis, or rights to purchase shares of common stock of Emmis,
issued pursuant to any employee stock option, equity incentive, profit-sharing
or other employee benefit plan approved by the Board of Directors of Emmis.

         (d) As used in this Section 8.03, the term

             (i) "New Securities" means any shares of common stock of Emmis or
any rights to subscribe for, purchase or otherwise acquire any share or shares
of common stock of Emmis;

             (ii) "Qualifying Rights" means, as of any time, all outstanding
rights to subscribe for, purchase or otherwise acquire any share or shares of
common stock of Emmis which, by their terms, are exercisable for shares of
common stock of Emmis only upon payment, conversion, surrender, exchange or
delivery by the holder of additional consideration in cash or property in an
amount or having a Fair Market Value per share of common stock of Emmis which,
as of such time, is equal to or less than the Fair Market Value per share of the
common stock of Emmis as of such time;

             (iii) "Fair Market Value" means, as to any securities or other
assets or property, the price at which a willing seller would sell and a willing
buyer would buy such securities, assets or property having full knowledge of the
facts, in an arm's-length transaction without time constraints, and without
being under any compulsion to buy or sell.

             (iv) "Permitted Assignee" means (A) any controlled Subsidiary of
Liberty to which Liberty transfers Purchased Shares and (B) any affiliate of
Liberty to which Liberty transfers Purchased Shares except that in the case of
clause (B), the rights granted under this Section 8.01 shall not apply in
respect of any Purchased Shares held by any such affiliate which are in excess
of one-third of the total number of Purchased Shares issued under this Agreement
(as adjusted to take into account stock splits, stock dividends,
reclassifications and similar transactions)

SECTION 8.04 Urban Stations. So long as Liberty and its affiliates retain in the
aggregate ownership of at least One Million Four Hundred Thousand (1,400,000) of
the Purchased Shares (as adjusted from time to time to account for any stock
dividend, stock split or reverse stock split), Emmis shall not, without
Liberty's prior written consent,
<PAGE>   31

directly or indirectly acquire an interest or invest in any joint venture, or
form any joint venture, with any radio broadcast company that derives more than
seventy percent (70%) of its broadcast cash flow or fifty percent (50%) of its
revenues from urban format radio stations. Emmis, however, shall in no manner be
restricted from acquiring any urban format radio station or from converting any
radio station owned by Emmis to an urban format.

SECTION 8.05 Strategic Alliance. Emmis and Liberty and will work together in
good faith to explore opportunities for a strategic alliance which would benefit
both Emmis or its Affiliates and Liberty or its Affiliates.

SECTION 8.06 Potential Future Venture.

     (a) In the event Liberty or any of its Affiliates determines to engage in
the radio broadcast business, Liberty or its affiliate may, but shall not be
obligated to, form a new entity ("Radio Entity") for the purpose of acquiring
radio broadcast properties with urban formats in major United States markets. If
requested by Liberty, Emmis agrees to make equity ownership investments in the
Radio Entity, provided that (i) the Radio Entity shall not own or acquire any
radio station in Los Angeles, (ii) Emmis' aggregate investment in Radio Entity
shall at no time exceed ten percent (10%) of the total cash capital
contributions by all owners of the Radio Entity, (iii) the aggregate amount of
all such investments by Emmis shall not exceed Fifty Million Dollars
($50,000,000), (iv) the business of the Radio Entity shall be limited to the
acquisition, ownership and operation of radio stations with urban formats in
major United States markets, and Emmis shall not be obligated to make a
particular equity investment in the Radio Entity unless such investment is
solely used to fund, contemporaneously with such investment, ten percent (10%)
of the purchase price of one or more such radio stations specified by Liberty in
its investment request, and (v) Emmis shall not be required to make any
investment in the Radio Entity if the investment would result in Emmis having an
attributable ownership interest, within the meaning of the FCC Attribution
Rules, in any broadcast license held by the Radio Entity.

     (b) No owner of an interest in Radio Entity shall receive any ownership
interest in Radio Entity in exchange for any services provided or to be provided
as a promoter or otherwise, and the economic rights and benefits of Emmis'
investment in Radio Entity shall be in proportion to the total cash investment
made by Emmis in Radio Entity compared to the total cash investments made by all
owners in Radio Entity. All transactions between Radio Entity, on the one hand,
and any of its owners or their respective Affiliates, on the other hand, shall
be on an arms-length basis, and Radio Entity shall be structured in a manner
that will provide each owner with reasonable

<PAGE>   32

liquidity opportunities. If Emmis is an investor in the Radio Entity at the time
that Radio Entity acquires any radio station in the New York or Chicago market,
Liberty shall request that Emmis invest, and Emmis shall be entitled to invest,
in Radio Entity in connection with such acquisition in accordance with clauses
(ii) through (v) of foregoing Subsection (a).

     (c) Except as contemplated by this Section, Emmis shall not be entitled to
participate or otherwise acquire any interest in Radio Entity. Regardless of
whether Emmis invests in Radio Entity, Emmis shall in no event be restricted in
any manner from owning, operating or acquiring any type of radio station in any
market, including, but not limited to, a radio station that competes with Radio
Entity in any market.

<PAGE>   34

SECTION 9.05 Assignment; Binding Effect; Benefit . Neither this Agreement nor
any of the rights, benefits or obligations hereunder may be assigned by any
party or Subsidiary or affiliate of any party without the prior written consent
of the other party; provided, however, that Liberty may, without such consent,
assign its rights under this Agreement to any controlled Subsidiary or affiliate
of Liberty in respect of any Purchased Shares that Liberty is permitted under
any other section of this Agreement to transfer to such entity. Such assignment
shall not relieve Liberty of its obligations hereunder in the event such
assignee fails to perform such obligations. Subject to the preceding sentence,
this Agreement will be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns. Nothing in this
Agreement, expressed or implied, is intended to confer on any person other than
the parties or their respective successors and assigns, any rights, remedies,
obligations or liabilities under or by reason of this Agreement, other than
rights conferred upon Indemnified Parties under Article VII.

SECTION 9.06 Amendment . This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties.

document delivered pursuant hereto, (iii) waive compliance by the other party
with any of the agreements or covenants of such other party contained herein or
(iv) waive any condition to such waiving party's obligation to consummate the
transactions contemplated hereby or to any of such waiving party's other
obligations hereunder. Any agreement on the part of a party hereto to any such
extension or waiver shall be valid only if set forth in a written instrument
signed on behalf of such party. Any such extension or waiver by any party shall
be binding on such party but not on the other party entitled to the benefits of
the provision of this Agreement affected unless such other party also has agreed
to such extension or waiver. No such waiver shall constitute a waiver of, or
estoppel with respect to, any subsequent or other breach or failure to comply
strictly with the provisions of this Agreement. The failure of any party to
insist on strict compliance with this Agreement or to assert any of its rights
or remedies hereunder or with respect hereto shall not constitute a waiver of
such rights or remedies. Whenever this Agreement requires or permits consent or
approval by any party, such consent or approval shall be effective if given in
writing in a manner consistent with the requirements for a waiver of compliance
as set forth in this Section 8.07.

<PAGE>   41

         (a) Request for Registration. In case the Company shall receive during

the Company effect any registration, qualification or compliance with respect to
Registrable Securities under the Securities Act, the Company will, as soon as
practicable but in no event more than 30 days from receipt by the Company of
such written request, use its reasonable best efforts to effect such
registration, qualification or compliance (including, without limitation,
appropriate qualification under applicable (if any) blue sky or other state
securities laws and appropriate compliance with applicable regulations issued
under the Securities Act and any other governmental requirements or regulations)
as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to effect any such registration, qualification or compliance pursuant
to this Section 2:

             (A) In any particular jurisdiction in which the Company would be
required to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the Securities
Act, nor in any jurisdiction in which the Company would be required to subject
itself to taxation by such act;

to a dividend reinvestment or direct stock purchase plan (DRIP) or with respect
to which Section 3(a) applies), and continuing up to the earlier of (x) 90 days
immediately following the effective date of any such registration statement
pertaining to securities of the Company, (y) the date when the Common Stock is
trading at an average (for the trailing 20 trading days) of 110% of the offering
price for such registration statement, and (z) the expiration of any lock-up
periods to which the Company is subject in an underwritten offering, provided
that the Company is actively employing in good faith all reasonable efforts to
cause any such registration statement to become effective;

             (D) If the Company shall furnish to the Initiating Investors a
certificate signed by the Chief Executive Officer of the

<PAGE>   42

Company stating that in the good faith judgment of the Board of Directors the
Company is in possession of material non-public information (including, but not
limited to, information regarding a contemplated debt or equity financing),
disclosure of which would cause a serious detrimental effect to the Company or
its shareholders if a registration statement were filed in the near future, then
the Company's obligation to use its reasonable best efforts to register, qualify
or comply under this Section 2(a) shall be deferred for a period not to exceed
45 days; provided, however, that in no event may the Company delay a
registration pursuant to this Section 2(E) more than once in any twelve (12)
month period;

             Subject to the foregoing clauses (A) through (D), the Company shall
give prompt written notice (the "Notice of Demand Request") of the Initiating
Investors' request to all Investors and, thereupon, the Company shall, as
expeditiously as possible, use its reasonable best efforts to effect the
registration under the Securities Act of (i) the Registrable Securities which
the Company has been so requested to register in the registration request, for
disposition in accordance with the intended method of disposition stated in the
registration statement and (ii) all other Registrable Securities the holders of
which shall have made a written request to the Company for registration thereof
within 30 days after the giving of the Notice of Demand Request, all to the
extent necessary to permit the sale or other disposition by the holders of the
securities to be registered. Whenever a requested registration is for a firmly
underwritten offering, if the managing underwriter for such offering determines
that the number of shares of Common Stock requested to be included that are to
be sold by Investors is limited due to market conditions, any shares of Common
Stock requested to be included by shareholders other than the Investors shall be
excluded and, if the number of shares of Common Stock must be further reduced,
the Investors proposing to sell their Registrable Securities in such
underwriting and registration shall share pro rata in the available portion of
the registration statement in question, such sharing to be based upon the number
of Registrable Securities then held by such Investors, respectively.

         (b) Form of Registration. The Company shall be entitled to use a Form
S-3 or any similar short form registration statement for a Demand Registration
if the Company is eligible to use such a form. Notwithstanding anything to the
contrary herein, if at any time the Company is not eligible to use a Form S-3 or
any similar short form registration statement for any reason, any references in
this Agreement to registrations on Form S-3 or any similar short form
registration statement shall be deemed to be references to registrations on Form
S-1 or any similar long form registration statement which the Company is then
eligible to use.

3.       Company Registration.

         (a) Notice of Registration. If at any time or from time to time the
Company shall determine to register any of its Common Stock, either for its own
account or the account of a security holder or holders (including but not
limited to registration of the sale of Common Stock which will be automatically
converted from Class B Common Stock, $.01 par value per share, upon sale), other
than (A) a registration relating solely to employee benefit plans, (B) a
registration relating solely to a Commission Rule 145 transaction, (C) a
registration relating to a dividend reinvestment or direct stock purchase plan
or (D) a shelf registration of multiple classes of securities for sale on a
delayed basis pursuant to Rule 415 under the Securities Act, or any subsequent
sale therefrom, the Company will:

             (i)  promptly give to the Investors written notice thereof; and

             (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all the Registrable Securities specified in a written request or
requests, made within 14 days after receipt of such written notice from the
Company, by the Investors; provided, however, if any registration pursuant to
this Section 3 involves an underwritten offering and the managing underwriter
shall advise the Company that, in its view, the number of securities requested
to be included in such registration exceeds the number that can be sold in an
orderly manner in such offering within a price range acceptable to the Company,
the Company shall include in such offering first, all the securities the Company
proposes to register for its own account, and second, the Registrable Securities
and securities to be sold for the account of other security holders, with each
Investor or other security holder proposing to sell Registrable Securities or
other securities participating in such registration on a pro rata basis, such
participation to be based upon the number of Registrable Securities or other
securities then held by such Investors or other security holders, respectively.

         (b) Right to Terminate Registration. The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 3
prior to the effectiveness of such registration whether or not the Investors
have elected to include Registrable Securities in such registration. Each
Investor who holds Registrable Securities included in the registration agrees
that, upon receipt of notice from the Company that the Company has determined to
withdraw any registration statement pursuant to this subsection, such Investor
will discontinue its disposition of securities pursuant to such registration
statement and, if so directed by the Company, will deliver to the Company (at
the Company's expense) all copies, other

<PAGE>   44

than permanent file copies, then in such Investor's possession of the prospectus
covering securities which was in effect at the time of such notice.

4.       Limitations on Subsequent Registration Rights. From and after the
date hereof, the Company shall not enter into any agreement granting any holder
or prospective holder of any securities of the Company registration rights with
respect to such securities that would allow such holder or prospective holder to
include such securities in any registration filed under Section 2 hereof, unless
under the terms of such agreement, such holder or prospective holder may include
such securities in any such registration only to the extent that the inclusion
of its securities will not reduce the amount of the Registrable Securities of
the Investors which is included.

5.       Expenses of Registration. All Registration Expenses incurred in
connection with all registrations shall be borne by the Company, except to the
extent that the Initiating Investors alone, but not the Company, initiate the
request that a Demand Registration be withdrawn prior to its effectiveness, and
if the Initiating Investors elect not to have such withdrawn registration
counted as a Demand Registration requested under Section 2 in which case all
Registration Expenses incurred in connection with that registration shall be
borne by the Initiating Investors on a pro rata basis. All Selling Expenses
relating to securities registered on behalf of the Investors shall be borne by
the Investors.

6.       Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to a request under
Section 2(a) or 3(a) of this Agreement, the Company will keep the Investors
advised in writing as to the initiation of each registration, qualification and
compliance and as to the completion thereof. The Company will use its reasonable
best efforts to effect the registration and the sale of such Registrable
Securities 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 Securities and use its reasonable best efforts to
cause such registration statement to become effective (provided that before
filing a Demand Registration statement or prospectus or any amendments or
supplements thereto, the Company will furnish to the counsel selected by the
Initiating Investors copies of all such documents proposed to be filed);

         (b) in the case of a Demand Registration, prepare and file with the
Commission such amendments and post-effective amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be
necessary to keep such registration

<PAGE>   45

statement effective for a period of not less than 120 days, and comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

         (c) during the period in which the Company is required under the
provisions hereof to keep a registration statement effective, furnish to the
seller of Registrable Securities such number of copies of such registration
statement, each amendment and supplement thereto, the prospectus included in
such registration statement (including each preliminary prospectus) and such
other documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

         (d) subject to Section 2(a)(A) - (D) herein, use its reasonable best
efforts to register or qualify such Registrable Securities under any applicable
securities or blue sky laws of such jurisdictions as any seller reasonably
requests and do any and all other acts and things which may be reasonably
necessary or advisable to enable such seller to consummate the disposition in
such jurisdictions of the Registrable Securities owned by such seller;

         (e) notify the seller of such Registrable Securities, any time the
Company becomes aware a prospectus relating thereto is required to be delivered
under the Securities Act, of the happening of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, subject to the rights of the Company to suspend or delay
sales stated elsewhere in this Agreement, at the request of such seller, the
Company will prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus will not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading;

         (f) use its reasonable best efforts to cause all such Registrable
Securities to be listed on each securities exchange on which similar securities
issued by the Company are then listed and, if not so listed, to be listed on the
NASD automated quotation system and, if listed on the NASD automated quotation
system, use its reasonable best efforts to secure designation of all such
Registrable Securities covered by such registration statement as a Nasdaq
National Market System Security within the meaning of Rule 11Aa2-1 of the
Commission or, failing that, use its best efforts to secure Nasdaq authorization
for such Registrable Securities;

<PAGE>   46

         (g) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

         (h) enter into such customary agreements (including underwriting
agreements in customary form with underwriters selected, in the case of a
registration under Section 2, by the Initiating Investors subject to the
Company's reasonable approval, not to be unreasonably withheld) and take all
such other actions as the holders of a majority of the Registrable Securities
being sold or the underwriters, if any, reasonably request in order to expedite
or facilitate the disposition of such Registrable Securities (including, without
limitation, (i) not effecting any public sale or distribution of its equity
securities, or any securities convertible into or exchangeable or exercisable
for such securities, during a period customary for such agreements of no more
than seven days prior to and no more than 90 days following the effective date
of any underwritten registration (except as part of such underwritten
registration or pursuant to registrations on Form S-8 or any successor form or
registrations involving dividend reinvestment or direct share purchase plans),
unless the underwriters managing the registered public offering otherwise agree,
and (ii) using its reasonable efforts to cause each executive officer and
director to agree not to effect any public sale or distribution (excluding sales
pursuant to Rule 144) of any such securities during such period (except as part
of such underwritten registration, if otherwise permitted), unless the
underwriters managing the registered public offering otherwise agree);

         (i) upon receipt and execution of such confidentiality agreements as
the Company may reasonably request from parties who are not otherwise subject to
confidentiality obligations because of the nature of their profession (e.g.,
underwriters, attorneys and accountants), make available for inspection by the
seller of Registrable Securities, any underwriter participating in any
disposition pursuant to such registration statement and any attorney, accountant
or other agent retained by any such seller or underwriter, all 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 any such seller, underwriter,
attorney, accountant or agent in connection with such registration statement
(including, without limitation, accountants' "cold comfort" letters and opinions
of counsel);

         (j) otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least 12 months beginning with the first day of the
Company's first full calendar

<PAGE>   47

quarter after the effective date of the registration statement, which earnings
statement shall satisfy the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder;

         (k) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company will use its reasonable best efforts promptly to
obtain the withdrawal of such order;

         (l) if the disposition of the Registrable Securities is pursuant to an
underwritten offering, cause the appropriate officers, underwriters and advisors
of the Company to meet with the investors whose Common Stock is registered for
resale thereunder.

7.       Indemnification.

         (a) The Company agrees to indemnify, to the extent permitted by law,
each holder of Registrable Securities, its officers and directors and each
person who controls such holder (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities and expenses arising out of or
based upon any untrue or alleged untrue statement of material fact contained in
any registration statement, prospectus or preliminary prospectus 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, in light of the circumstances under which they were made, not
misleading, except insofar as losses, claims, damages, liabilities or expenses
are caused by written information supplied by or on behalf of such holder
specifically for use in the preparation of such registration statement,
prospectus or preliminary prospectus relating to such holder's ownership of
Registrable Securities or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with the number of copies of the
same reasonably requested by such holder.

         (b) In connection with any registration statement in which a holder of
Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits relating to such holder's
ownership of Registrable Securities or as otherwise required under the
Securities Act as the Company reasonably requests for use in connection with any
such registration statement or prospectus and, to the extent permitted by law,
will indemnify the Company, its directors and officers and each person who
controls the Company (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses resulting from any untrue or

<PAGE>   48

alleged untrue statement of material fact contained in the registration
statement, prospectus or preliminary prospectus 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, in
light of the circumstances under which they were made, 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 such holder which was
expressly provided for use in such registration statement and was included in
such registration statement in reliance on and in conformity with such written
information or affidavit.

         (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 or not
defended because of a conflict of interest pursuant to clause (ii) of the
preceding sentence, 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, unless (A) in
the reasonable judgment of any indemnified party a conflict of interest may
exist between such indemnified party and any other of such indemnified parties
with respect to such claim or (B) such counsel is not admitted to practice in a
jurisdiction where an action is pending, in which case the indemnified parties
shall pay the fees and expenses of one additional firm of attorneys to act as
local counsel in such jurisdiction.

         (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. If recovery is
not available under the foregoing indemnification provisions, for any reason
other than as specified therein, the parties entitled to indemnification by the
terms thereof shall be entitled to contribution for any and all losses, claims,
damages or liabilities, joint or several, and expenses to which they may become
subject, in such proportion as is appropriate to reflect the relative fault of
the parties entitled to indemnification, on the one hand, and the indemnifying
parties, on the other, in connection with the matter out of which such losses,
claims,

<PAGE>   49

damages, liabilities or expenses arise or result from. In determining the amount
of contribution to which the respective parties are entitled, there shall be
considered the parties' relative knowledge and access to information concerning
the matter with respect to which the claim was asserted, the opportunity to
correct and prevent any statement or omission, and any other equitable
considerations appropriate under the circumstances.

8.       Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, for so
long as any Investor owns Registrable Securities, the Company agrees to use its
reasonable best efforts to:

         (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times
hereafter.

         (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Securities
Exchange Act of 1934, as amended.

         (c) So long as any Investor owns any Registrable Securities, to furnish
to such Investor forthwith upon request a written statement by the Company as to
its compliance with the reporting requirements of Rule 144 and of the Securities
Act and the Securities Exchange Act of 1934, and a copy of the most recent
annual or quarterly report of the Company.

9.       Transfer of Registration Rights. Subject to the termination
provisions of Section 10 and the definition of "Registrable Securities," the
rights granted to the Investors hereunder may be assigned, in connection with
any transfer or assignment of Registrable Securities by an Investor, to any
affiliate of the assigning Investor.

10.      Termination of Registration Rights. The Company's obligations
pursuant to Sections 2, 3 and 4 shall expire when (i) all Registrable Securities
held by the Investors or any assignee have been sold or transferred in any
manner to any person or entity, including, but not limited to, sales pursuant to
a registration statement, Rule 144 sales or otherwise, but excluding any sale or
transfer in connection with which the rights of any Investor hereunder are
assigned pursuant to Section 9, or (ii) all Registrable Securities have ceased
to be Registrable Securities, whichever first occurs.

11.      Confidentiality. Each Investor hereby agrees that it shall maintain
in confidence, and shall not use or disclose without the prior written consent
of the Company, any information identified as confidential that is furnished to
it by the Company in connection with

<PAGE>   50

this Agreement, including (without limitation) all financial statements, budget
and other information delivered or provided to such Investor. This obligation of
confidentiality shall not apply, however, to any information (a) in the public
domain through no unauthorized act or failure to act by such Investor, (b)
lawfully disclosed to such Investor by a third party who possessed such
information without any obligation of confidentiality, or (c) known previously
by such Investor or lawfully developed by such Investor independent of any
disclosure by the Company. Each Investor further agrees that it shall return to
the Company or destroy all tangible materials containing such information upon
request by the Company.

12.      Miscellaneous.

         (a) Governing Law. This Agreement shall be governed in all respects by
the internal laws of the State of Indiana.

         (b) Survival. The representations, warranties, covenants and agreements
made herein shall survive any investigation made by the Investors and the
closing of the transactions contemplated hereby.

         (c) Successors and Assigns. The provisions hereof shall inure to the
benefit of, and be binding upon, the successors, permitted assigns, heirs,
executors and administrators of the parties hereto, including as specifically
provided by Section 10 hereof.

         (d) Entire Agreement; Amendment. This Agreement and its attachments
constitute the full and entire understanding and agreement between the parties
with regard to the subject hereof. Except as expressly provided herein, neither
this Agreement nor any term hereof may be amended, waived, discharged or
terminated other than by a written instrument signed by the Company and
Investors holding at least 67% of the Registrable Securities.

         (e) Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be enforceable against the parties actually
executing such counterparts, and all of which together shall constitute one
instrument.

         (f) Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

         (g) Titles and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not considered in construing or
interpreting this Agreement.
