             (b) The Company will cause Arthur Andersen L.L.P. (the "Company's
Auditors") to perform an audit of the Company (the "Audit"). The Audit shall
include a schedule depicting Net Book Value as of December 31, 1998 shall be
prepared by the Company in accordance with GAAP applied on a basis consistent
with those applied in the preparation of the Company's 1997 financial statements
except that the schedule will not give effect to any asset impairment reserves,
if any, which would otherwise be required by GAAP. In addition, the schedule
depicting Net Book Value shall give effect to the inclusion of the Total
Intercompany Financing Transactions (including assignments, if any, referred to
in 3.2(h)) in Net Book Value as of December 31, 1998 and otherwise be presented
in a form consistent with Schedule II, Exhibit A. The Net Book Value schedule
shall be accompanied by a certified special purpose report ("Special Purpose
Report") which identifies procedures to be performed by the Company's Auditors
as determined by the Company and Investor. The Company shall submit the Special
Purpose Report, together with all applicable workpapers of Investor and their
auditors, KPMG Peat Marwick LLP ("Investors's Auditors") for review and
acceptance. If the Audit is reviewed and accepted by Investor's Auditors prior
to the Closing, then the Purchase Price shall be as determined utilizing the
Audit. If the Audit is not reviewed and accepted by Investor's auditors on or
prior to the Closing, then ZNC shall provide its best estimate of Net Book Value
(the "Estimate") to Investor at least five business days prior to the Closing,
and Investor shall have the opportunity to review and accept the estimate (which
acceptance shall not be unreasonably withheld). If the Estimate is used and
accepted by Investor, then the Investor Note will be 


                                       1
<PAGE>   6

issued utilizing the Estimate. Following the Closing, when Net Book Value is
finally determined as provided in Section 2.1, the Investor Note shall be
canceled and replaced with an Investor Note that reflects the Purchase Price
determined utilizing the Audit.

             (c) If following the Closing Date, the Company's Auditors and
Investor's Auditors reach agreement on the Audit, then the Net Book Value as of
December 31, 1998, shall be as so agreed, and the Investor Note shall be
accordingly completed to reflect such Net Book Value determination; provided,
that (i) if the difference between the Estimate and the Audit is an amount that
exceeds the Estimate multiplied by five percent (5%) (the "5% Amount"), then the
Net Book Value used to determine the Purchase Price shall be an amount equal to
(A) the Estimate plus (B) the 5% Amount and (ii) if the difference between the
Estimate and the Audit is an amount that is less than the 5% Amount, then the
Net Book Value used to determine the Purchase Price shall be an amount equal to
(A) the Estimate minus (B) the 5% Amount (the "Lowest Net Book Value");
provided, further that if the Net Book Value is determined by the Audit to be
less than the Lowest Net Book Value, ZNC shall contribute capital to the Company
(without receiving any capital stock, promissory notes or other securities) in
an amount equal to the difference between the Net Book Value determined by the
Audit and the Lowest Net Book Value, in order to increase the Company's actual
Net Book Value to equal the Lowest Net Book Value. If following the Closing Date
the Company's Auditors and Investor's Auditors are unable to reach agreement on
any material term of the Audit (being defined as amounts in excess of $100,000
in the aggregate), then, at the request of either auditors, the disagreement
shall be submitted to PricewaterhouseCoopers, L.L.P. (the "Third-Party
Auditors") for its determination, which determination shall be final and binding
on the Parties. The Parties acknowledge and agree that there shall not exist as
a basis for disagreement any previously utilized and disclosed capitalization
policies of the Companies. Each Party shall bear its own cost and expense in
connection with this Section 2.1 (with the costs and expenses of the Companies
being borne by ZNC), with the cost and expenses of the Third-Party Auditors
being split equally between Investor and ZNC.

             (d) In addition to the possible adjustment provided in
subparagraphs (b) and (c) above, upon the date of the actual Closing, an
adjustment to the Purchase Price (and a corresponding adjustment to the Investor
Note (either an increase or decrease, as the case may be)), shall be made to
reflect the operating results of the Companies for the period from January 29,
1999 to the Closing Date (with the Investor Note either being: (i) decreased by
an amount equal to 25% of the consolidated net income of the Companies for such
period; or (ii) increased by an amount equal to 25% of the consolidated net loss
of the Companies for such period.

         2.2 INVESTOR'S LOAN TO THE COMPANY. At the Closing, Investor shall loan

additional twenty-five percent (25%) of the issued and outstanding HOP Interests
on a fully-diluted basis in addition to any other HOP Interests owned by AHC; it
being understood and agreed that (i) at the Closing AHC will own 25% of the
issued and outstanding HOP Interests on a fully-diluted basis, and (ii) upon

         2.3 OPTION TO PURCHASE COMMON STOCK OF INVESTOR. At the Closing,
Investor shall grant to ZNC options to purchase up to 150,000 shares of common

Capital Notes"). The Company may request drawdowns under the Working Capital
Notes from time to time upon written request to Investor and ZNC as provided in
the Working Capital Notes; it being agreed that all such drawdowns shall be
split equally between Investor and ZNC. The proceeds of the Working Capital
Notes shall be used by the Company for short-term working capital needs of the
Companies. Any future working capital needs of the Companies that are not

easements, restrictions, encroachments and conditions which do not have a
material adverse effect on the use of such asset (collectively, the "Permitted

authorization, execution, delivery and performance of the Transaction Documents
by Investor and the performance of all of Investor's obligations hereunder have
been taken. The Transaction Documents executed by Investor are valid and binding

similar laws of general application relating to or affecting the enforcement of
creditor rights or the relief of debtors, (b) laws and judicial decisions
regarding indemnification for violations of federal securities laws, and (c) the

Investor is acting on its own behalf in connection with the investigation and
examination of the Company and its decision to execute these documents.

         5.3 SHARES PURCHASED FOR INVESTMENT. Investor agrees that any shares of
Common Stock acquired in accordance with the transactions contemplated by this
Agreement shall be acquired solely for Investor's own account and not as a
nominee or agent for any other person, for investment, and not with a view to,
or for offer or resale in connection with, any distribution thereof within the
meaning of the Securities Act or other applicable securities laws. Investor
understands that if any shares of Common Stock so acquired have not been
registered under the Securities Act or under any applicable blue sky or other
state securities law or regulation (hereinafter collectively referred to as
"blue sky laws"), Investor cannot offer for sale, sell, pledge, transfer or
otherwise dispose of such shares of Common Stock unless such shares of Common
Stock have been registered under the Securities Act and under any applicable
blue sky laws, or unless an exemption from such registration is available with
respect to any such proposed offer, sale, pledge, transfer or other disposition.
Investor agrees that a restrictive legend addressing the foregoing restrictions
on transfer may be placed on certificates representing any shares of Common
Stock so acquired and that transfer of such shares of Common Stock may be
refused by the Company or its transfer agent, if any, if in the opinion of
counsel to the Company any proposed sale or other disposition thereof by
Investor would not be in compliance with the Securities Act or any other
applicable federal securities laws or blue sky laws.

         5.4 BROKERAGE. There are no claims for brokerage commissions, finder's
fees or similar compensation in connection with the transactions contemplated by

government or agency which would conflict with, or in any way impact, Investor's
ability to perform its duties hereunder, or have a material adverse effect on
Investor's financial position.

         5.6 ORGANIZATION. Investor is a corporation duly organized, validly
existing and in good standing under the laws of the State of Texas. Investor is
not barred or otherwise prevented from doing business in any jurisdiction where
the failure to conduct such business would have a material adverse effect on
Investor.

         5.7 EFFECT OF TRANSACTIONS. The execution, delivery and performance of
this Agreement by Investor, and the consummation of the transactions
contemplated by the Transaction Documents, does not and will not violate any
terms of the Articles of Incorporation or Bylaws of Investor or violate any
judgment, decree or order, or any material contract or obligation of Investor,
or any material statute, rule or regulation of any federal, state or local
government or agency applicable to Investor.

         5.8 FINANCIAL STATEMENTS. The consolidated balance sheets and the
related statements of income, shareholders' equity and cash flow (including the
notes related thereto) of Investor and its consolidated subsidiaries included in

         5.9 POWER. Investor has all required corporate power and authority to

                                   ARTICLE 8.
                                 INDEMNIFICATION

         8.1 INDEMNIFICATION BY ZNC. Subject to the terms and conditions of this
Article 8, ZNC agrees to indemnify, defend and hold Investor and its directors,
officers, agents, attorneys and affiliates harmless from and against all losses,
claims, obligations, demands, assessments, penalties, liabilities, costs,
damages, attorneys' fees and expenses (collectively, "Damages"), asserted

Investor contained herein or in any exhibit, schedule or certificate delivered

         8.3 LIMITATIONS ON INDEMNIFICATION OBLIGATIONS.

             (a) Except as provided in (b) below, neither ZNC nor Investor shall
be liable for Damages in an amount exceeding $8 million (the "Maximum Amount").

             (b) Neither ZNC nor Investor shall be liable for indemnification
under Article 


                                       20
<PAGE>   25

8 until the aggregate amount of Damages incurred by the other party exceeds One
Hundred Thousand Dollars ($100,000) (the "Threshold Amount"); provided, however,
that if the Damages exceed the Threshold Amount, then such indemnifying party's
obligation under this Article 8 shall be the difference between the Maximum
Amount of the Damages and the Threshold Amount; and provided further, however,
that the Threshold Amount shall not apply to the Damages in excess of $10,000
arising out of the matters set forth in SCHEDULE 4.8(f); and provided further,
however, that neither the Maximum Amount nor the Threshold Amount shall apply to
the matters set forth in the last sentence of SECTION 8.1 above.

         8.4 CONDITIONS OF INDEMNIFICATION. The respective obligations and
liabilities of ZNC and Investor (the "indemnifying party") to the other (the
"party to be indemnified") under Sections 8.1 and 8.2 with respect to claims
resulting from the assertion of liability by third parties shall be subject to
the following terms and conditions:

             (a) Within 20 days (or such earlier time as might be required to
avoid prejudicing the indemnifying party's position) after receipt of notice of
commencement of any action evidenced by service of process or other legal
pleading, the party to be indemnified shall give the indemnifying party written
notice thereof together with a copy of such claim, process or other legal
pleading, and the indemnifying party shall have the right to undertake the
defense thereof by representatives of its own choosing and at its own expense;
provided that the party to be indemnified may participate in the defense with
counsel of its own choice, the fees and expenses of which counsel shall be paid
by the party to be indemnified unless (i) the indemnifying party has agreed to
pay such fees and expenses, (ii) the indemnifying party has failed to assume the
defense of such action or (iii) the named parties to any such action (including
any impleaded parties) include both the indemnifying party and the party to be
indemnified and the party to be indemnified has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the indemnifying party (in which case, if
the party to be indemnified informs the indemnifying party in writing that it
elects to employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the party to be indemnified, it being understood, however, that the
indemnifying party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for the party to be indemnified, which firm shall be designated in writing
by the party to be indemnified).

             (b) In the event that the indemnifying party, by the 30th day after
receipt of notice of any such claim (or, if earlier, by the 10th day preceding
the day on which an answer or other pleading must be served in order to prevent
judgment by default in favor of the person asserting such claim), does not elect
to defend against such claim, the party to be indemnified will (upon further
notice to the indemnifying party) have the right to undertake the defense,
compromise or settlement of such claim on behalf of and for the account and risk
of the indemnifying party and at the indemnifying party's expense, subject to
the right of the indemnifying party to assume the defense of such claims at any
time prior to settlement, compromise or final determination thereof.

             (c) Notwithstanding the foregoing, the indemnifying party shall not
settle any claim without the consent of the party to be indemnified unless such
settlement involves only the payment of money and the claimant provides to the
party to be indemnified a release from all liability in respect of such claim.
If the settlement of the claim involves more than the payment of money, the
indemnifying party shall not settle the claim without the prior consent of the
party to be indemnified.

             (d) The party to be indemnified and the indemnifying party will
each cooperate with all reasonable requests of the other.


                                       21
<PAGE>   26

             (e) Any claim shall be net of the receipt of any insurance proceeds
paid to a Party under any policy or policies of insurance covering the loss
giving rise to the claim. Each Party will use reasonable efforts to collect any
such insurance and will account to the other Party therefor. Each Party agrees
to respond promptly to any inquiry by the other Party as to the status of any
such insurance payment.

         8.5 WAIVER. No waiver by any party of any default or breach by another
party of any representation, warranty, covenant or condition contained in this
Agreement, any exhibit or any document, instrument or certificate contemplated
hereby shall be deemed to be a waiver of any subsequent default or breach by
such party of the same or any other representation, warranty, covenant or
condition. No act, delay, omission or course of dealing on the part of any party
in exercising any right, power or remedy under this Agreement or at law or in
equity shall operate as a waiver thereof or otherwise prejudice any of such
party's rights, powers and remedies. All remedies, whether at law or in equity,
shall be cumulative and the election of any one or more shall not constitute a
waiver of the right to pursue other available remedies.

         8.6 REMEDIES EXCLUSIVE. The remedies provided in this Article 8 shall
be the exclusive remedies available to the parties, except in the case of fraud.

         8.7 OFFSET. Any and all amounts owing or to be paid by any Party to any
other Party, hereunder or otherwise, shall be subject to offset and reduction
PRO TANTO by any amounts ("Offset Amounts") that have been determined by a court
of competent jurisdiction or by settlement of the Parties or by agreement of the
Parties to be owing at any time by such other Party to such Party in respect of
any failure or breach of any representation, warranty or covenant of such other
Party under or in connection with the Transaction Documents with such Party or
any transaction contemplated hereby or thereby.

         8.8 INDEMNIFICATION, COSTS, EXPENSES AND LEGAL FEES. Each Party that is
shown to have breached the Transaction Documents hereby agrees to pay the costs
and expenses (including reasonable attorneys' fees and expenses) incurred by any
other Party in successfully (i) enforcing any of the terms of this Agreement
against such breaching Party or (ii) proving that another Party breached any of
the terms of this Agreement.

         8.9 SPECIFIC PERFORMANCE. The Parties acknowledge that a refusal by a
Party to consummate the transactions contemplated hereby will cause irreparable
harm to the other Parties, for which there may be no adequate remedy at law and
for which the ascertainment of damages would be difficult. Therefore, a Party
shall be entitled, in addition to, and without having to prove the inadequacy
of, other remedies at law, to specific performance of this Agreement, as well as
injunctive relief (without being required to post bond or other security).

         8.10 INSURANCE AND WARRANTIES. With respect to Damages that may be
subject to insurance recovery or manufacturer's warranty, Article 8 shall not be
enforced against the indemnifying party until the party to be indemnified has
first made a claim for Damages against the appropriate insurer or manufacturer.
Notwithstanding the foregoing, the party to be indemnified may (a) give notice
of such possible claim immediately and (b) pursue indemnification against the
indemnifying party under this Article 8 upon the earlier of (i) rejection of
such claim; or (ii) the passage of nine months from the date such claim was
submitted if no resolution has been reached with the insurer or manufacturer.
The indemnifying party shall be entitled to an assignment of the rights against
such insurer or manufacturer upon payment of such indemnification claim up to
the amount so indemnified.

         8.11 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations
and warranties contained herein shall survive the Closing and all statements
contained in any certificate, exhibit or other instrument delivered by or on
behalf of ZNC, the Company or Investor pursuant to this Agreement shall be
deemed to have been representations and warranties by ZNC, the Company or
Investor, as the case may be, and, notwithstanding any provision in this
Agreement to the contrary, shall survive the Closing for a period of eighteen
months from the Closing Date; provided, however, that the representations
contained in (a) Section 4.14 above shall survive 


                                       22
<PAGE>   27

until the expiration of the applicable statute of limitations, and (b) Section
4.25 above shall survive the Closing for a period of three years from the
Closing Date. Notwithstanding the above, if prior to any expiration date the
indemnifying party shall have been notified of a claim for indemnity hereunder
and such claim shall not have been finally resolved or disposed of at such date,
any representation or warranty that is the basis for such claim shall continue
to survive as to such claim and shall remain a basis for indemnity, to the
extent of such claim only, until such claim is finally resolved or disposed of.

                                   ARTICLE 9.
                                   TERMINATION

         9.1 TERMINATION. This Agreement may be terminated:

             (a) At any time prior to the Closing Date by mutual agreement of
ZNC and Investor.

             (b) At any time prior to the Closing Date by Investor if any
representation or warranty of ZNC, the Company or HOP contained in this
Agreement or in any certificate or other document executed and delivered by ZNC,
the Company or HOP pursuant to this Agreement is untrue when made or if ZNC, the
Company or HOP fails to comply in any material respect with any covenant
contained herein, and any such misrepresentation, noncompliance or breach is not
cured, waived or eliminated within five days after written notice.

             (c) At any time prior to the Closing Date by ZNC if any
representation or warranty of Investor contained in this Agreement or in any
certificate or other document executed and delivered by Investor pursuant to
this Agreement is untrue when made or if Investor fails to comply in any
material respect with any covenant contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within five days after written notice.

             (d) By either Investor or ZNC if the Closing has not occurred by
the Closing Date.

In the event this Agreement is terminated pursuant to subparagraph (b), (c) or
(d) above, Investor and ZNC shall each be entitled to pursue, exercise and
enforce any and all remedies, rights, powers and privileges available at law or
in equity. In the event of a termination of this Agreement under the provisions
of this Article, a Party not then in material breach of this Agreement shall
stand fully released and discharged of any and all obligations under this
Agreement.

         Notwithstanding any termination, this Agreement remains in full force
and effect as to the deliveries made at signing (as provided in SECTION 2.11
