                           they keep their books and records.

                  Purchasers shall not unreasonably delay consent to or
rejection of any of the actions described in this Section 3.2(a). To the extent
that Seller takes or fails to take action on any matter described in this
Section 3.2(a) in accordance with instructions given to it by the Designated
Representative (or deemed to have been given in accordance with paragraph (c)
below), Purchasers shall be deemed to have waived in respect of such matter any
right they may otherwise have to claim a breach of a representation or to assert
any claim hereunder.

                  (b) Ascent Arena Entities and the Development Property. From
the Effective Date through the Closing Date, neither Seller nor any Ascent Arena
Entity shall take any action or fail to take any action if such action or
inaction, as the case may be, would be outside the ordinary course of business
and inconsistent with past practices, except as specifically contemplated by the
terms of this Agreement (including the City Transfer and the matters described
in Sections 3.2(e), 3.2(f), 9.11 and 9.14). Notwithstanding the foregoing,
except as specifically contemplated by the terms of this Agreement (including
the City Transfer and the matters described in Sections 3.2(e), 3.2(f), 9.11 and
9.14), neither Seller nor any Ascent Arena Entity shall take any of the
following actions without the prior written consent of Purchasers:

                           Pepsi Center, the Development Property, or the Assets
                           of any Ascent Arena Entity, except the City Lien, the
                           Trustee's Lien, Liens created in the ordinary course
                           of business consistent with past practices related to
                           sponsorship agreements and other contracts disclosed
                           on Schedule 5.13(e) and except pursuant to the Arena
                           Contracts after consultation with the Designated
                           Representative;

                           (ii) sell, transfer or convey, or enter into any
                           Contract (including any Contract that grants any
                           Person any right to use, access, lease or acquire any
                           of the Intellectual Property Assets of any of the
                           Ascent Arena Entities) with a value in excess of
                           $500,000 which grants any Person any right to use,

                           term of one year or less or for a term that is
                           terminable without penalty or premium at the option

                           Entity, except pursuant to the Arena Contracts after
                           consultation with the Designated Representative;

                  Purchasers shall not unreasonably delay consent to or
rejection of any of the actions described in this Section 3.2(b). To the extent
that Seller takes or fails to take action on any matter described in this
Section 3.2(b) in accordance with instructions given to it by the Designated
Representative (or deemed to have been given in accordance with paragraph (c)
below), Purchasers shall be deemed to have waived in respect of such matter any
right they may otherwise have to claim a breach of a representation or to assert
any claim hereunder.

                  (c) Designated Representative. Purchasers shall appoint a
person(s) to serve as primary contact for Seller in conjunction with Sections
3.2 and 3.5 (the "Designated Representative"). For purposes of Seller seeking
required approvals under this Section 3.2, Seller shall deliver written
notification (in the manner provided in Section 10.1) to the Designated
Representative as to the matter for which Seller is seeking approval. The
Designated Representative may grant or deny approval within 48 hours of such
notification or indicate that it shall accede to management's judgment. If the
Designated Representative does not deliver such written notification within the
48-hour period or indicates that it shall accede to management's judgment, such
approval shall be deemed to have been given.

                  (d) Notice. Seller shall promptly notify Purchasers, in
writing, of the occurrence or existence of any event or circumstance of which
Seller or any Purchased Entity is aware and which would (i) violate this Section
3.2, or (ii) make the satisfaction of any condition in Section 7.1 impossible or
unlikely.

                  (e) Approved Budgets. Seller has delivered to Purchasers, and
Purchasers have approved, operating and capital budgets for the period from
April 1, 2000 through September 30, 2000 for the following: (i) Nuggets LP, (ii)
Avalanche LLC, (iii) Ascent Arena Company, (iv) LLC-I, and (v) LLC-II (the
"Approved Budgets"). Expressly subject to the limitations and covenants provided
in Article III, Seller may take any actions or make any expenditures
substantially in accordance with the Approved Budgets without the prior written
consent of Purchasers.

                  (f) Intercompany Loans. Between the Balance Sheet Date and the
Closing Date, all revenues, cash, funds, notes, accounts receivable and the
like, of any kind, received by the Purchased Entities, including funds received
by any Purchased Entity with respect to season tickets, club seats, luxury
suites, television, radio, marketing, sponsorships or advertising, including
deferred revenues relating to prepayments for any such items (collectively, the
"Interim Period Funds"), will be retained by the Purchased Entities and may be
used by the Purchased Entities to pay for operating expenses and capital
expenditures relating to the Business in accordance with the Approved Budgets
(the "Interim Period Expenses"). If the Interim Period Funds are not sufficient
to pay the Interim Period Expenses, Seller or Liberty Media Corporation shall
advance funds to the Purchased Entities in an amount sufficient to cover the
shortfall between the amount of the Interim Period Expenses and the amount of
the Interim Period Funds, and any such advances shall be treated as intercompany
loans, which shall bear interest at the per annum rate of interest publicly
announced from time to time by The Bank of New York as its prime rate (or
reference rate) plus 1%, from Seller or Liberty Media Corporation, as the case
may be, and the Purchased Entities (the "Interim Period Intercompany Loans"). If
at any time between the Balance Sheet Date and the Closing Date the


                                     - 23 -

<PAGE>   30


Purchased Entities have excess Interim Period Funds not required to pay Interim
Period Expenses, such excess Interim Period Funds may be used to repay, in whole
or in part, any Interim Period Intercompany Loans. On the Closing Date, any
unpaid principal balance of and any accrued but unpaid interest on any Interim
Period Intercompany Loans shall be paid by the Purchased Entities to Seller or
Liberty Media Corporation, as applicable, in full; provided, however, that if
the Purchased Entities do not have sufficient cash and cash equivalents on the
Closing Date to repay all outstanding Interim Period Intercompany Loans in full,
all cash and cash equivalents of the Purchased Entities will be used to repay in
part the Interim Period Intercompany Loans and any remaining balance of the
Interim Period Intercompany Loans will be forgiven and discharged, and provided
further, that if the Closing occurs after June 30, 2000, then (x) Seller or
Liberty Media Corporation shall be entitled at Closing to repayment in full of
any Interim Period Intercompany Loans made after June 30, 2000 (the "Post-June
30 Loans"), and Purchasers will provide cash to the Purchased Entities (either
as a loan or as a contribution, at the option of Purchasers) immediately prior
to the Closing, to the extent that the Purchased Entities otherwise would not
have sufficient cash and cash equivalents to repay the Post-June 30 Loans in
full, and (y) any revenues, cash, funds, notes, accounts receivable and the like
received by the Purchased Entities after June 30, 2000, shall not be used to
repay any Interim Period Intercompany Loans made before June 30, 2000.
Notwithstanding any of the preceding provisions of this Section 3.2(f) to the
contrary, if any one or more of the Purchased Entities make any expenditure or
advance of funds prior to Closing in connection with establishment of a strike
fund as required by the NHL (the "NHL Strike Fund Amount") and if the Purchased
Entities would not have sufficient cash and cash equivalents at Closing to repay
all Interim Period Intercompany Loans in full, Purchasers will provide cash to
the Purchased Entities (either as a loan or as a contribution, at the option of
Purchasers) immediately prior to Closing, in an amount equal to the lesser of
(i) the NHL Strike Fund Amount, and (ii) the amount of the Interim Period
Intercompany Loans that would otherwise not be repaid in full if Purchasers did
not provide cash to the Purchased Entities immediately prior to the Closing.

         3.3 Preservation of Business. From the Effective Date through the
Closing Date, Seller shall cause the Purchased Entities to use their respective
reasonable best efforts to preserve intact the current Assets, business
organizations and relationships, and goodwill of the Purchased Entities, and to
keep available the services of the present officers, employees, players, agents
and other personnel of the Purchased Entities, excluding officers of Seller who
are not Key Employees, in each case to the extent commercially reasonable.

         3.4 Maintenance of Insurance Coverage and Certain Policies. From the
Effective Date through the Closing Date, neither Seller nor any of the Purchased
Entities shall take or fail to take any action if such action or inaction, as
the case may be, would adversely affect the applicability, prior to the Closing
Date, of any insurance policies listed on Schedule 3.4. Seller shall maintain
the insurance policies listed on Schedule 3.4 in effect through the Closing
Date.

         3.5 Current Information. From the Effective Date through the Closing
Date, Seller will cause one or more of its representatives to confer on a
regular basis with the Designated Representative with respect to the status of
the ongoing operations of the Purchased Entities. Seller promptly will notify
Purchasers of any material change in the normal course of business of the

Authority or of any litigation known to Seller (or written communications
received by Seller or the Purchased Entities indicating that the same may be
contemplated) or, if known to Seller or the Purchased Entities, the institution
or the threatened institution of any litigation in each case that would
challenge, prevent, alter or materially delay any of the transactions
contemplated by the Transaction Documents and Seller will keep Purchasers
informed with respect to such events. Seller and Purchasers will notify each
other at mutually agreeable times of the status of applications with
Governmental Authorities and third party consents related to the transactions
contemplated by the Transaction Documents. In addition, Seller will deliver
promptly to Purchaser copies of all internal financial reports regularly
prepared by or for Seller and Returns filed with any Governmental Authority, and
will allow Purchasers and/or their representatives reasonable access to any and
all records, files, contracts, employees, representatives, agents and other
information or Persons deemed necessary by Purchasers and/or their
representatives to verify representations and warranties made by Seller herein
and other information provided by Seller to Purchasers in connection with the
transactions contemplated by the Transaction Documents.

         3.6 Preservation of LDA's Ascent Arena Company Membership Interest. LDA
agrees not to sell or otherwise transfer, pledge, hypothecate or encumber the
LDA Ascent Arena Company Membership Interest prior to the Closing.

                           in good standing under the laws of the jurisdiction

                           (ii) has full power and authority to own, lease and
                           operate its Assets and to conduct its Business as now

                           states and other jurisdictions where its ownership,
                           leasing or operation of its Assets, or the conduct of
                           its Business, requires such qualification or
                           licensing, except where the failure to be so
                           qualified or registered would not result in a
                           Material Adverse Effect.

                  (b) Organizational Documents. The Purchased Entities have
delivered or made available to Purchasers true and complete copies of their

                           (ii) The execution, delivery and performance of the
                           Transaction Documents and the consummation of the
                           transactions contemplated thereby have been duly

                           Entities' Employee Plans and all related summary
                           descriptions, including copies of any employee
                           handbooks listing or describing any Purchased
                           Entities' Employee Plans and summary descriptions of
                           any Purchased Entities' Employee Plan not otherwise
                           in writing.

                           (ii) Except for any failure or default that would not
                           have a Material Adverse Effect, each of the Purchased
                           Entities has fulfilled or has taken all actions
                           necessary to enable it to fulfill when due all of its
                           obligations under each Purchased Entities' Employee
                           Plan. To the Knowledge of Seller, there are no
                           negotiations, demands or proposals which are pending
                           or which have been made to Seller or the Purchased
                           Entities which concern material matters now covered,
                           or that would be covered, by any Purchased Entities'
                           Employee Plan that would have a Material Adverse
                           Effect.

                           (iii) Each of the Purchased Entities is in full
                           compliance with all Applicable Law applicable to each
                           Purchased Entities' Employee Plan except where
                           noncompliance would not have a Material Adverse
                           Effect. There has been no Employee Plan Event which
                           is continuing or in respect of which there is any
                           outstanding liability of any of the Purchased
                           Entities that, individually or in the aggregate,
                           would have a Material Adverse Effect, and no such
                           Employee Plan Event is reasonably expected to occur,
                           with respect to any Purchased Entities' Employee
                           Plan.

                           execution and delivery of the Transaction Documents
                           and the conclusion of the transactions contemplated
                           by this Agreement will not cause the acceleration of
                           vesting in, or payment of, any benefits under any
                           Purchased Entities' Employee Plan.

                           (v) None of the Purchased Entities has any formal
                           plan or commitment, whether legally binding or not,
                           to create any additional Employee Plan or to modify
                           or change any existing Employee Plan that would
                           affect any current or former employee of any of the
                           Purchased Entities.

                           (vi) Schedule 5.6(a)(i) separately identifies any
                           Purchased Entities' Employee Plan that provides life
                           insurance or employee welfare plan benefits (within
                           the meaning of section 3(1) of ERISA), now or in the
                           future, to any former employee at any cost to any of
                           the Purchased Entities (except as required by
                           Applicable Law).

                  (b) Employee Plans of the Purchased Entities' ERISA
Affiliates. Except as would not have a Material Adverse Effect, there has been
no Employee Plan Event with respect to any Employee Plan of any Person that is
an ERISA Affiliate of the Purchased Entities or who was an ERISA Affiliate of
the Purchased Entities at any time since December 31, 1993, in respect of which
any liability could be expected to be incurred by any of the Purchased Entities.

                  (c) Purchased Entities' Qualified Plans.

                           (i) Each Purchased Entities' Qualified Plan has
                           received a favorable determination letter (or opinion
                           letter) from the IRS providing that each such plan
                           satisfies the requirements of section 401(a) of the
                           Code, and each trust under each such plan is exempt
                           from Taxes under section 501(a) of the Code. To the
                           Knowledge of Seller, no event has occurred that will,
                           or would reasonably be expected to, give rise to
                           disqualification or loss of tax-exempt status of any
                           such plan or trust under such sections.

                           (ii) Seller and the Purchased Entities have made
                           available to Purchasers for each Purchased Entities'

                           applicable: (A) the Form 5500 filed for each of the
                           three most recent plan years, including all schedules
                           thereto and financial statements with attached
                           opinions of independent accountants; and (B) the most
                           recent determination letter from the IRS.

                  (d) Purchased Entities' ERISA Plans and Multiemployer Plans.
No Purchased Entities' Employee Plan is, and no Employee Plan maintained by any
of the Purchased Entities during the three-year period prior to the date hereof
was, an ERISA Plan. None of the Purchased Entities has during the three-year
period prior to the date hereof contributed to, or withdrawn in a complete or
partial withdrawal from, any Multiemployer Plan or incurred any contingent
liability under section 4204 of ERISA, nor is there any current potential
liability for withdrawal from a Multiemployer Plan, in either case that would
have a Material Adverse Effect, except as disclosed in Schedule 5.6(d).

         5.7 Labor and Employment Matters.

                  (a) Except as set forth in Schedule 5.7(a), (i) to the

Date, neither Seller, the Purchased Entities, nor any of their respective
Controlled Affiliates has received any written notice or has Knowledge of any
threatened labor or civil rights dispute, controversy or grievance or any other
unfair labor practice proceeding or breach of contract claim or action with
respect to claims of, or obligations to, any employee or group of employees of
any Purchased Entity, and the same will be true as of the Closing Date, except
as would not have a Material Adverse Effect.

                  (c) Schedule 5.8(a) sets forth a complete and correct list of
all material agreements (i) pursuant to which the Purchased Entities have
licensed Intellectual Property, or have permitted any Person to use Intellectual
Property, and (ii) pursuant to which the Purchased Entities have been granted a
license to Intellectual Property. All such agreements (A) are in full force and
effect in accordance with their terms and no default exists thereunder by the
Purchased Entities, or to the Knowledge of Seller, by any other party thereto,
(B) are free and clear of all Liens, and (C) do not contain any
change-in-control provisions or other terms or conditions that will become
applicable or inapplicable as a result of the Closing, except as may be provided
in Contracts listed on Schedule 5.8(a).

                  (d) Except as set forth in Schedule 5.8(a), no claim or demand

Intellectual Property, (ii) asserts that the Purchased Entities are infringing
upon the intellectual property rights of another, or (iii) claims that any
default exists under any Contract listed in Schedule 5.8(a), in each case that

with any court, arbitrator, or administrative agency, or has been the subject of

<PAGE>   46


                  (b) To the Knowledge of Seller, each Purchased Entity has been
and currently is in compliance in all material respects with all terms and
conditions of all Authorizations of all Governmental Authorities (and all other
Persons) required under all Environmental Laws, including the VCUP, and is also
in compliance in all material respects with all other limitations, restrictions,
conditions, standards, requirements, schedules and timetables required or

                  (b) Ascent Arena Entities' Insurance Policies. The Ascent

                  (a) Purchased Entities and Predecessor Entities.

                           (i) All Returns required to be filed by or on behalf
                           of any Purchased Entity, and all Returns required to
                           be filed by or on behalf of any Predecessor Entities
                           (which, together with the Purchased Entities, are
                           each referred to herein individually as a "P&P
                           Entity" and collectively as the "P&P Entities"), have
                           been duly filed on a timely basis and all Returns
                           filed by or on behalf of each P&P Entity (including
                           all attached statements and schedules) are true,
                           complete and correct in all respects, except for such
                           failures to file and failures to be true, complete
                           and correct as would not, individually or in the
                           aggregate, have a Material Adverse Effect. No claim
                           has been made or threatened in writing by any
                           jurisdiction where a P&P Entity does not file Returns
                           that the P&P Entity is or may be subject to Taxes in
                           that jurisdiction. All Taxes shown to be payable on
                           such Returns or on subsequent assessments with
                           respect thereto have been paid in full on a timely
                           basis. No other Taxes are payable by any P&P Entity
                           with respect to items or periods covered by such
                           Returns (whether or not shown on or reportable on
                           such Returns), except for such Taxes as would not,
                           individually or in the aggregate, have a Material
                           Adverse Effect.

                           (ii) Each P&P Entity has withheld and paid over all
                           Taxes required to have been withheld and paid over
                           (including any estimated Taxes), and has complied
                           with all information reporting and backup withholding
                           requirements, including maintenance of required
                           records with respect thereto, in connection with
                           amounts paid or owing to any employee, creditor,
                           independent contractor or other third party, except
                           for such failures to withhold or pay over and such
                           failures to comply as would not, individually or in
                           the aggregate, have a Material Adverse Effect.

                           (iii) There are no Liens on any of the Assets of a
                           P&P Entity with respect to Taxes, other than Liens
                           for Taxes not yet due and payable or for Taxes that
                           are being contested in good faith through appropriate
                           proceedings and for which appropriate reserves have
                           been established, except for such Liens as would not,
                           individually or in the aggregate, have a Material
                           Adverse Effect.

                           Purchasers, during normal business hours, true and
                           complete copies of all Returns of each P&P Entity for

                           a P&P Entity or on its behalf relating to Taxes of
                           any P&P Entity for any period beginning after
                           December 31, 1995 (and with respect to periods
                           beginning on or before December 31, 1995, any

                           of deficiencies, closing or other agreements received

                           Seller's possession), and Purchasers shall be
                           permitted to inspect and make copies of such Returns,
                           audit reports, work papers, statements and
                           agreements.

                           (v) Each of the Purchased Entities, other than the
                           Denver Arena Trust, LLC-I and LLC-II, has been
                           properly classified as a "partnership" for federal
                           income tax purposes, at all times since its
                           formation. (Each Purchased Entity that is classified
                           as a partnership for federal income tax purposes as
                           of the Closing Date is referred to herein as a
                           "Partnership Entity.") Each of LLC-I and LLC-II has

                           federal income tax purposes at all times since
                           formation (that is, for federal income tax purposes,

                           entity). The Denver Arena Trust has been properly
                           treated as a "disregarded entity" for federal income
                           tax purposes at all times since its formation (that

                           Trust is and has been at all times treated as a
                           division of Ascent Arena Company and not as a
                           separate entity). Each Predecessor Entity was at all
                           times prior to its merger or liquidation into a
                           Purchased Entity properly classified as a corporation
                           for federal income tax purposes (each such
                           Predecessor Entity that was at any time classified as
                           a corporation for federal income tax purposes being
                           referred to herein as a "Corporate Entity").

                           (vi) (A) Except as disclosed on Schedule
                           5.11(a)(vi)(A), there are no audits, inquiries,
                           investigations or examinations relating to any
                           Returns referred to in Section 5.11(a)(i) pending or,
                           to the Knowledge of Seller, threatened in writing.

                           asserted in writing with respect to Taxes of any P&P

                                    (C) No P&P Entity is a party to any action
                           or proceeding for assessment or collection of Taxes,
                           nor has such action or proceeding been asserted or
                           threatened in writing against it or any of its
                           assets.

                                    (D) Except as set forth on Schedule
                           5.11(a)(vi)(D), no Corporate Entity has ever been
                           included in an affiliated group of corporations,
                           within the meaning of section 1504 of the Code, and
                           none has ever been a member of any combined or
                           unitary group, in each case other than a group the

                           or before the Balance Sheet Date, determined on a
                           GAAP basis (taking into account the Return

                           the current liability accruals for Taxes (excluding
                           reserves for deferred Taxes) as of that date, and the
                           amount of a P&P Entity's liability for unpaid Taxes

                           amount of the current liability accruals for Taxes
                           (excluding reserves for deferred Taxes) as such
                           accruals will be reflected on the balance sheet of

                           relevant current liability accrual amount would not
                           have a Material Adverse Effect.

                                   ARTICLE VI.

                  REPRESENTATIONS AND WARRANTIES OF PURCHASERS

         As an inducement to Seller to enter into this Agreement, Purchasers, as
applicable, each represent, warrant and covenant to Seller, that the following
matters are true and correct as of the Effective Date and as of the Closing Date
unless limited to a specific date.

         6.1 Existence and Power. Each Purchaser is a limited liability company
duly formed, validly existing and in good standing under the laws of the State
of Missouri, and will be duly registered in and authorized by the State of
Colorado to transact business in the State of Colorado as of the Closing Date
(or as of such earlier date as may be required by the City). Each Purchaser has
all power and authority to enter into this Agreement and to carry out and
perform its obligations under the terms of this Agreement and any other
Transaction Document to which it is a party. The execution, delivery and
performance of the Transaction Documents and the consummation of the
transactions contemplated thereby have been duly authorized by all necessary
action on the part of each Purchaser. This Agreement and each other Transaction
Document constitutes a legal, valid and binding agreement of each Purchaser,
enforceable against it in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, or similar laws affecting
the enforcement of creditors' rights generally or by equitable principles
relating to enforceability.

         6.2 Governmental Authorization. The execution, delivery and performance
by Purchasers of this Agreement and each other Transaction Document require no
action by, consent or approval of, or filing with, any Governmental Authority
other than:

                  (a) compliance with any applicable requirements of the HSR Act
with respect to the consummation of the transactions contemplated hereby;

                  (b) compliance with the registration requirements of the
Securities Act, or an exemption therefrom, and any applicable state blue sky
laws; and

                  (c) as set forth in this Agreement.

         6.3 Non-Contravention. The execution, delivery and performance by
Purchasers of this Agreement and each other Transaction Document does not and
will not (a) contravene or conflict with the limited liability company
agreements of Purchasers, (b) contravene or conflict with or constitute a
violation of any Applicable Law binding upon or applicable to Purchasers, (c)
constitute a default under any contract, agreement or other commitment to which
any Purchaser is a party or by which any Purchaser is bound, or (d) contravene
or conflict with or constitute a violation of, or require any consent or
approval under or filing under, any rules or regulations of the National
Football League that are binding upon or applicable to Purchasers, Kroenke or
any Person in which Kroenke or any Affiliate of Kroenke has an interest.

         6.4 Securities Matters.

                  (a) The Equity Interests are being acquired for Purchasers'
own accounts, for investment and not with a view to, or for resale in connection
with, any distribution or public offering thereof within the meaning of the
Securities Act.

                  (b) Purchasers understand that the Equity Interests have not
been registered under the Securities Act by reason of their issuance in a
transaction exempt from the registration and prospectus delivery requirements of
the Securities Act pursuant to section 4(2) thereof, that Seller has no present
intention of registering the Equity Interests, that the Equity Interests must be
held by Purchasers indefinitely, and that Purchasers must therefore bear the
economic risk of such investment indefinitely, unless a subsequent disposition
thereof is registered under the Securities Act or is exempt from registration.

                  (c) During the negotiation of the transactions contemplated
herein, Purchasers and their representatives have been furnished with and have
had access to such information as Purchasers have considered necessary to make a
determination as to the purchase of the Equity Interests, have been afforded an
opportunity to ask such questions of Seller and the Purchased Entities'
officers, employees and representatives concerning the Purchased Entities'
business, operations, financial condition, assets, liabilities and other
relevant matters as they have deemed necessary or desirable, and have been given
all such information as has been requested, in order to evaluate the merits and
risks of the prospective investments contemplated herein.

                  (d) Purchasers and their representatives have been solely
responsible for Purchasers' own due diligence investigation of the Purchased
Entities and its management and business, for their own analysis of the merits
and risks of this investment, and for their own analysis of the fairness and
desirability of the terms of the investment. In taking any action or performing
any role relative to the arranging of the proposed investment, Purchasers have
acted solely in their own interest, and no Purchaser (or any of their agents or
employees) has acted as an agent of Seller.

                  (e) Each Purchaser (i) has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risk of such Purchaser's prospective investment in the Equity Interests; (ii)
has the ability to bear the economic risks of such Purchaser's prospective
investment, including a complete loss of Purchaser's investment in the Equity
Interests; and (iii) has not been offered the Equity Interests by any form of
advertisement, article, notice or other communication published in any
newspaper, magazine, or similar media or broadcast over television or radio, or
any seminar or meeting whose attendees have been invited by any such media.

         6.5 Advisory Fees. No Purchaser has retained or authorized any
investment banker, broker, finder or other intermediary or advisor to act on
behalf of Purchasers or their Affiliates who might be entitled to any fee,
commission or reimbursement of expenses from Purchasers, Seller or any of its
respective Affiliates upon consummation of the transactions contemplated by this
Agreement.

         6.6 Litigation. There is no proceeding pending or, to the knowledge of
Kroenke or any Purchaser, threatened against or affecting Kroenke or any
Purchaser before any court or arbitrator or any governmental body, agency or
official, that in any manner challenges or seeks to prevent, enjoin, alter or
materially delay the transactions contemplated by the Transaction Documents.

         6.7 Beneficial Ownership.

                  (a) The Persons who "beneficially own" (within the meaning of
section 13(d)(3) of the Securities Exchange Act of 1934, as amended) any
interests in Purchasers (such Persons collectively referred to as the
"Principals," and individually as a "Principal"), and the amount of such
interests each such Principal "beneficially owns," are set forth on Schedule
6.7(a). No other Person not listed on Schedule 6.7(a) has or will have as of the
Closing Date any right, contract, agreement, arrangement or understanding with
respect to any interests in any Purchaser.

                  (b) Purchasers and the Principals understand and acknowledge
that each of the City, the NBA and the NHL have various requirements regarding
the suitability of owners of, respectively, Ascent Arena Company, an NBA
franchise and an NHL franchise, and Purchasers and the Principals are familiar
with such requirements. To the knowledge of Purchasers and the Principals, no
Person listed on Schedule 6.7(a) has: (i) ever had a petition under the federal
bankruptcy laws or any state bankruptcy or insolvency laws filed by or against
such Person or any partnership in which such Person was a general partner at the
time of or within two years prior to such filing, any limited liability company
in which such Person was a member at the time of or within two years prior to
such filing, or any corporation or business association of which such Person was
an executive officer or director at the time of or within two years prior to
such filing; (ii) been convicted in a criminal proceeding or been named subject
of a pending criminal proceeding (excluding minor traffic violations or other
minor offenses); (iii) been the subject of any order, judgment, or decree not
subsequently reversed, suspended or vacated, of any Governmental Authority,
permanently or temporarily enjoining such Person from, or otherwise limiting
such Person from, engaging in any type of business activity; (iv) ever had any
ties to or relationships with organized crime or any Persons involved in
organized crime; or (v) engaged in any illegal, unethical or inappropriate
conduct that could reasonably be expected to serve as a basis for any of the
City, the NBA or the NHL to not approve Purchasers or any Principals as an owner
of, respectively, Ascent Arena Company, the Nuggets or the Avalanche.
Additionally, each of the Principals has a net worth and financial liquidity
that are reasonably expected to meet the requirements of the City, the NBA and
the NHL.

         6.8 No Other Representations. Seller acknowledges that Purchasers and
the Principals have not made and do not make, and Seller has not relied on, any
representation or warranty, whether express or implied, of any kind or character
except as expressly set forth in this Article VI.

         6.9 Financial Matters. Purchasers have, or at Closing will have,
sufficient funds available to consummate the transactions contemplated by this
Agreement.

                           proceeding relating to any proposed adjustment.

                  (f) Notification of Proceedings. In the event that Purchasers
receive written notice of any Tax matter with respect to a P&P Entity that could
affect Seller, or Seller receives written notice of any Tax matter with respect
to a P&P Entity that could affect Purchasers, the party receiving such written
notice shall notify in writing the potentially affected party within five
Business Days after receipt of such notice. The failure of any party to give the
notice required by this Section 9.5(f) shall not impair that party's rights
under this Agreement except to the extent that the other party demonstrates that
it has been damaged or prejudiced thereby.

                  (g) Cooperation.

                           (i) After the Closing, Seller and Purchasers shall,
                           each at its own expense, cooperate with each other
                           and with each other's agents, including accounting
                           firms and legal counsel, in connection with the
                           preparation or audit of any Return, refund claim or
                           Tax controversy matter with respect to any P&P Entity
                           or its activities. Such cooperation shall include
                           making available any information, records and
                           documents in their possession or under their control
                           related to any P&P Entity that is relevant to the
                           preparation or audit of any Return, refund claim or
                           Tax controversy matter with respect to any P&P Entity
                           or its activities. Any information provided or
                           obtained under this paragraph shall be kept
                           confidential, except as may otherwise be necessary in
                           connection with the filing of a Return, refund
                           claims, tax audits, tax claims or tax litigation or
                           as required by law.

                           (ii) Seller shall have the right to control, at its
                           expense, any Tax Proceeding (as defined below) to the
                           extent such proceeding relates to any Tax issue that
                           could give rise to a liability of Seller to
                           Purchasers under Section 9.5(d)(i) (a "Liability
                           Issue"). Seller shall furnish to Purchasers copies of
                           any inquiries or requests for information from any
                           taxing authority concerning any Liability Issue, and
                           Seller shall furnish to Purchasers advance written
                           notification of the position(s) that Seller intends
                           or expects to take in such Tax Proceedings.
                           Purchasers shall have the right to consult with
                           Seller regarding any response to such requests.
                           Seller shall provide to Purchasers copies of all
                           written communications and documents submitted to any
                           taxing authority with respect to a Liability Issue.
                           Seller and Purchasers shall each furnish to the
                           other, promptly after receipt, a copy of all
                           information document requests, notices of proposed
                           adjustment, revenue agent's reports or similar
                           reports or notices of deficiency together with all
                           relevant documents and memos related to the foregoing
                           documents, notices or reports, relating to any
                           Liability Issue. Notwithstanding the foregoing,
                           Seller shall not take or propose to take any
                           unreasonable position in any Tax Proceeding involving
                           or with respect to any of the P&P Entities. Every
                           position that Seller proposes to take in such Tax
                           Proceedings shall be deemed to be reasonable unless
                           Purchasers provide to Seller a written opinion of
                           nationally recognized tax counsel that concludes that
                           the position taken by Seller is unreasonable. In that
                           event, Seller shall cease to maintain such position
                           unless and until Seller is able to provide to
                           Purchasers a written opinion of nationally recognized
                           tax counsel that the position that Seller is taking
                           is reasonable.

                           (iii) Subject to the provisions of subparagraph (ii)
                           above, Purchasers shall have complete control over
                           the handling, disposition and settlement of any Tax
                           controversy with respect to a Purchased Entity,
                           including any


                                     - 66 -

<PAGE>   73


                           administrative, judicial or other proceeding in
                           connection with any Tax controversy (a "Tax
                           Proceeding").

                  (h) Record Retention. Seller and Purchasers shall retain and
provide to each other upon reasonable request any records or other information
(including accounting work papers) that is in their possession or readily
obtainable and may be relevant to any Return, audit or examination, proceeding,
or determination that affects any amount required to be shown on any Return of a
P&P Entity for any period. Without limiting the generality of the foregoing,
Seller and Purchasers shall retain, until the applicable statutes of limitations
(including any extensions) have expired, copies of all Returns, supporting work
papers, and other records or information that may be relevant to such Returns of
a P&P Entity and shall not destroy or otherwise dispose of any such records
without first providing the other party with a reasonable opportunity to review
and copy the same.

                  (i) Treatment of Purchase. For federal income tax purposes,
Seller and Purchasers shall treat the purchase of 100% of the membership
interests in LLC-I and LLC-II as the purchase of the assets of LLC-I and LLC-II
pursuant to Revenue Ruling 99-5.

                  (j) Allocation of Purchase Price. Within 75 days after the
Closing Date, Purchasers will deliver to Seller proposed Schedule 9.5(j) (the
"Allocation Schedule"), which shall set forth an allocation of the total amount
of the consideration paid by Purchasers to Seller in connection with the
consummation of the transactions contemplated by this Agreement to the Assets
acquired by Purchasers from Seller hereunder. The allocation shall take into
account an appraisal prepared by PricewaterhouseCoopers, or another nationally
recognized appraiser reasonably acceptable to Purchasers and Seller, who shall
be retained by Purchasers at Purchasers' expense. Seller shall reasonably
cooperate in providing information and assistance to any such appraiser. Within
ten Business Days after delivery of the Allocation Schedule by Purchasers to
Seller, Seller will notify Purchasers in writing whether Seller approves or
disapproves the Allocation Schedule; provided, however, that Seller will not
disapprove the Allocation Schedule unless Seller determines in its reasonable
judgment that (i) either the appraisal is not reasonably supportable or the
allocation proposed by Purchasers on the Allocation Schedule is not reasonably
consistent with the appraisal, and (ii) that the allocation proposed by
Purchasers on the Allocation Schedule will result in Seller being required to
recognize both ordinary income and capital loss in an amount that is more than
de minimus. Unless Seller disapproves the Allocation Schedule pursuant to the
immediately preceding sentence, the Allocation Schedule will be attached to and
incorporated as part of this Agreement within 90 days after the Closing Date,
and all parties to this Agreement shall prepare and file all applicable Returns
in a manner consistent with the allocation set forth on the Allocation Schedule.

         9.6 Employee Benefit Plans.

                  (a) This Section 9.6 contains the covenants and agreements of
the parties with respect to the employee benefits and employee benefit plans
provided or covering the employees of the Purchased Entities. Nothing herein
expressed or implied confers upon any such employee any rights or remedies of
any nature or kind whatsoever under or by reason of this Section 9.6.


                                     - 67 -

<PAGE>   74


                  (b) Purchasers agree to cause the Purchased Entities' Employee
Plans to be maintained substantially in accordance with their current terms and
conditions, except to the extent any change may be required by Applicable Law,
through the first anniversary of the Closing Date.

                  (c) Purchasers agree to cause to be made available on and
after the Closing Date to employees of the Purchased Entities on the Closing
Date who participate in Seller's 401(k) Plan ("Seller's 401(k) Plan") a 401(k)
plan sponsored by LLC-I (the "Ascent Sports 401(k) Plan"). The Ascent Sports
401(k) Plan shall, through the first anniversary of the Closing Date, provide
benefits, and contain terms and provisions, substantially the same as provided
under Seller's 401(k) Plan. The Ascent Sports 401(k) Plan shall accept direct
and indirect rollovers of such employees' account balances in Seller's 401(k)
Plan, including direct rollovers of any outstanding employee loans under
Seller's 401(k) Plan in kind. To the extent that distributions from Seller's
401(k) Plan to the employees of the Purchased Entities are prohibited by law, as
determined by Seller, Seller and Purchasers agree to use their reasonable best
efforts to effect a transfer of the account balances (including participant
loans, if any, and any portion of such accounts attributable to qualifying
employer securities, as defined in ERISA section 407) of the employees of the
Purchased Entities held in Seller's 401(k) Plan to the Ascent Sports 401(k) Plan
within a reasonable period of time after the Closing Date.

                  (d) Each welfare plan (within the meaning of section 3(1) of
ERISA) or policy maintained or sponsored by the Purchased Entities or by
Purchaser in which any employees of the Purchased Entities who currently
participate in welfare plans maintained by Seller will be eligible to
participate shall (i) permit such employees to enroll in such plans effective
upon the Closing Date, subject to satisfaction of any eligibility requirements
but without regard to any waiting periods, (ii) waive any pre-existing condition
limitation or exclusion and (iii) credit all payments made for health care
expenses during the current plan year of Seller's plans for purposes of
satisfying deductible, co- insurance and maximum out-of-pocket provisions for
the balance of the current plan year of the Purchased Entities' or Purchasers'
plans.

                  (e) Purchasers shall (i) cause the Purchased Entities to
continue, for the balance of the current plan year, any Code section 125
cafeteria plans based on the current elections of the participants who are
employed by the Purchased Entities on the Closing Date; or (ii) establish a
similar Code section 125 cafeteria plan that will accept transfers of account
balances from any Code section 125 cafeteria plans in which employees of the
Purchased Entities participate.

         9.7 Publicity. The parties hereto understand and acknowledge that
Seller will be obligated to disclose promptly after signing all of the material
terms and conditions of this Agreement, and shall thereafter be required to file
this Agreement with the Securities and Exchange Commission. Subject to the
foregoing, the parties agree that no press release will be made by Seller or
Purchasers or any of their respective agents concerning the transactions
contemplated under this Agreement until such release has been reviewed by and
coordinated with the other parties.

         9.8 Costs and Expenses. Seller and Purchasers shall each be responsible
for and bear their own costs and expenses incurred in connection with the
transactions contemplated under this


                                     - 68 -

Agreement; provided, however, that Seller and Purchasers shall each pay one-half
of any HSR Act filing fees required to be paid in connection with the
transactions contemplated under this Agreement.

         9.9 Conditions to Closing. Subject to the terms and conditions of this
Agreement (including Sections 9.10, 9.11, 9.12 and 9.13), Seller and Purchasers
shall use all reasonable efforts to satisfy the applicable conditions to the
Closing set forth in Article VII.

         9.10 City Consent. Purchasers and Kroenke shall use their reasonable
efforts to obtain the City Consent, including, if requested by the City, (a)
Kroenke will execute a guarantee of the obligations under the Arena Agreement
and the Ground Lease with the City to be entered into upon the City Transfer, in
form and substance reasonably satisfactory to Kroenke and the City; provided,
however, that a guarantee substantially similar to the guarantee in favor of the
City provided by AEG, the form of which is attached as an exhibit to the Arena
Agreement, will be deemed to be reasonably acceptable to Kroenke, and (b)
Purchasers and Kroenke will grant or cause to be granted for the benefit of the
City security interests in one or more Persons holding, directly or indirectly,
all of the interests in the Purchased Entities or any successor entities that
hold all of the interests in the Nuggets, Avalanche and Pepsi Center, in form
and substance reasonably satisfactory to Purchasers, Kroenke and the City,
subject to an inter-creditor agreement pursuant to which any lender to
Purchasers would agree to subordinate to any such security interests granted for
the benefit of the City.

         9.11 NBA and NHL Consents. Subject to the last sentence of this Section
9.11, any other provision of this Agreement to the contrary notwithstanding
(including any covenants of Seller in Article III), nothing in this Agreement
will be deemed to restrict the ability of Seller or any Affiliate of Seller to
take (or agree to take) or refrain from taking (or agree to refrain from taking)
any action required by the NBA or NHL in order to obtain any consents required
with respect to the transactions contemplated by this Agreement, subject to
Purchaser's consent, which will not be unreasonably withheld or delayed, except
that Purchasers' consent will not be required in connection with (i) any
resolution of the pending dispute between the Avalanche and the NHL concerning
certain television rights in favor of the NHL, (ii) execution by Seller or any
Purchased Entity of any Consent Agreement of the Avalanche and any Agreement and
Undertaking of the Nuggets in connection with obtaining approval of the NHL and
the NBA with respect to the acquisition of control of Seller and the Purchased
Entities by Liberty Media Corporation, or (iii) any action taken by Seller or
any Affiliate of Seller if such action will not be binding on any Purchased
Entity immediately after the Closing. Nothing contained in this Section 9.11
will be deemed (a) to require Seller or any Affiliate of Seller to take or agree
to take any action, including any action that Seller or any Affiliate of Seller
specifically is not required to take pursuant to Section 9.13 or (b) to conflict
with or be inconsistent with the provisions of Section 7.1(g).

         9.12 Purchase and Sale of LDA Ascent Arena Membership Interest. If
required by the NBA or NHL to obtain consents to the transactions contemplated
by this Agreement, LDA will sell to Purchasers, and Purchasers will acquire from
LDA, the LDA Ascent Arena Membership Interest for a purchase price equal to the
LDA Ascent Arena Membership Interest Value.

         9.13 Limitations on Required Actions. Any other provision of this
Agreement to the contrary notwithstanding except Section 9.12, in no event shall
Purchasers or any Affiliate of Purchasers or Seller or any Affiliate of Seller
(specifically including Liberty Media Corporation and AT&T Corp.) be required to
take, or agree to take, any extraordinary actions, including any of the
following actions, in order to satisfy any applicable conditions to the Closing,
including to obtain any required approval of the NBA or NHL or the City Consent:
(a) payment of any consideration other than customary fees required to be paid
to the NBA and NHL consistent with past transactions and any reasonable and
customary filing or application fees, (b) acceptance of any requirement to
divest, hold separate, or otherwise rearrange the composition of, any portion of
its assets or business, (c) acceptance of the imposition of any material
limitations on its ability effectively to exercise full rights of ownership of
any assets (including the right to vote any shares of stock in any Person or
voting rights with respect to any other equity interests in any Person), (d)
acceptance of any condition that would make the holding of any assets (including
shares of stock or other equity interests in any Person) illegal or subject to
any materially burdensome requirement or condition, or (e) acceptance of any
requirement to cease or refrain from engaging in any business; provided,
however, that with respect to Purchasers or any Affiliate of Purchasers, in no
event will the provisions of paragraphs (b), (c), (d) or (e) be deemed to apply
to any direct or indirect interest in any sports team, including the St. Louis
Rams, owned by Kroenke, Purchasers or any Affiliate of Purchasers.

         9.14 Amendment of Ascent Operating Agreement. Promptly after the
Effective Date, KMS Sports and LDA will negotiate in good faith to reach
agreement on a form of Amended and Restated Operating Agreement for Ascent Arena
Company to be entered into on the Closing Date, which will be based on the

         10.6 Entire Agreement. Except as otherwise provided herein, this
Agreement (including the Schedules and Exhibits referred to herein, which are
hereby incorporated by reference) constitutes the entire agreement between the
parties with respect to the subject matter hereof and supersedes all prior
agreements, understandings and negotiations, both written and oral, between the
parties with respect to the subject matter of this Agreement. Neither this
Agreement nor any provision hereof is intended to confer upon any Person other
than the parties hereto any rights or remedies hereunder.

         10.7 Captions. The captions herein are included for convenience of
reference only and shall be ignored in the construction or interpretation
hereof. All references to an Article or Section include all subparts thereof.

         10.8 Severability. If any provision of this Agreement, or the
application thereof to any Person, place or circumstance, shall be held by a
court of competent jurisdiction to be invalid, unenforceable or void, the
remainder of this Agreement and such provisions as applied to other Persons,
places and circumstances shall remain in full force and effect only if, after
excluding the portion deemed to be unenforceable, the remaining terms shall
provide for the consummation of the transactions contemplated hereby in
substantially the same manner as originally set forth at the later of the date
this Agreement was executed or last amended.

         10.9 Construction.

                  (a) The language used in this Agreement will be deemed to be
the language chosen by the parties hereto to express their mutual intent, and no
rule of strict construction shall be applied against either party. Any reference
to any Applicable Law shall be deemed also to refer to all rules and regulations
promulgated thereunder, unless the context requires otherwise. Whenever required
by the context, any gender shall include any other gender, the singular shall
include the plural and the plural shall include the singular. The words
"herein," "hereof," "hereunder," and words of similar import refer to the
Agreement as a whole and not to a particular section. The words "include,"
"includes" and "including" shall be deemed followed by the phrase "without
limitation."

                  (b) In the event of a conflict or inconsistency between any
provision contained in this Agreement and any provision contained in any of the
Schedules or Exhibits to this Agreement, the provision in the Agreement shall be
controlling.

         10.10 Cumulative Remedies. Except as provided in Section 9.5, the
rights, remedies, powers and privileges herein provided are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law. Each
of Seller and Purchasers acknowledges that a party and its Affiliates will
suffer irreparable damage if the other party does not perform its obligations
under this Agreement, and without limiting other rights or remedies to which a
party may be entitled, agrees that with respect to such obligations, an
injunction may be issued without the requirement of any bond or other security
and enforcement may be obtained by a decree of specific performance.

         10.11 Survival of Representations and Covenants. Except for the
representations and warranties in Sections 5.1, 5.2 and 5.17 which shall survive
for the applicable statute of limitations period, the representations and
warranties and covenants and agreements to be performed by their terms prior to
the Closing contained in this Agreement or in any other document delivered
pursuant to this Agreement shall not survive the consummation of the
transactions contemplated by this Agreement or the termination of this Agreement
in accordance with its terms. Covenants and agreements to be performed by their
terms in whole or in part after the Closing (including covenants and agreements
in Section 9.5(d)) will survive the consummation of the transactions
contemplated by this Agreement in accordance with their terms.

         10.12 No Third Party Beneficiaries. Except as expressly provided in
this Agreement, including the guarantee contemplated by Section 9.4, no Person
other than Purchasers and Seller shall have any right, benefit or obligation
under this Agreement as a third party beneficiary or otherwise.
