ITEM 5.       ACQUISITION OR DISPOSITION OF ASSETS.

       Effective June 30, 1997, Cotton Valley Resources Corporation (the
"Registrant") acquired Aspen Energy Corporation, a New Mexico corporation ("Old
Aspen"), by merger with a wholly-owned Nevada subsidiary corporation.  The
acquisition closed on July 31, 1997 and has been accounted for as a purchase.
The purchase price for the acquisition consisted of $500,000 cash and short-
term notes and 2,511,317 shares of the Registrant's common stock, no par value,
of which 270,000 shares were returned to the Registrant by two Old Aspen
shareholders in settlement of notes payable to Old Aspen in the amount of
$425,000.  The principal asset acquired was an interest in the Means (Queen
Sand) Unit in Andrews County, Texas.  The acquisition also included an
interest, having less than $500,000 in value, in two wells in Utah, which have
been sold for $200,000, two wells in Latimer County, Oklahoma, one well in
Harrison County, Texas and several shallow wells in Gregg County, Texas.

       On February 18, 1998, Leon A. Romero, the former president of Old Aspen,
was elected to the Registrant's Board of Directors to serve until the next
meeting of shareholders at which directors are elected or his sooner death,
resignation or removal.

The following unaudited pro forma combined statement of operations is derived
from the financial statements of Cotton Valley Resources Corporation (the
"Company") and Aspen Energy Corporation.  In July 1997, the Company acquired 
100% of the common stock of Aspen for a purchase price consisting of $200,000 in
cash, $300,000 non-interest bearing six month notes and 2,241,000 shares of the
Company's common stock (net of 270,000 shares transferred back to the Company to
retire $425,000 of loans from Aspen to the Aspen stockholders).  The Unaudited
Pro Forma Income Statement for the year ended June 30, 1997 has been prepared
assuming the acquisition had been consummated as of the beginning of the fiscal
year.

The unaudited combined pro forma financial statements should be read in
conjunction with the notes thereto and with the financial statements of the
Company as included in its Form 10-KSB and the financial statements of Aspen
included herein.

The unaudited combined pro forma financial statements are not indicative of the
financial position or results of operations of the Company which would actually
have occurred if the acquisition of Aspen had occurred at the date presented or
which may be obtained in the future.  In addition, future results may vary
significantly from the results reflected in such statements due to normal oil
and gas production declines, changes in prices paid for oil and gas, future
acquisitions, drilling activity and other factors.

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
                        FOR THE YEAR ENDED JUNE 30, 1997


(1)     Adjustments to add Aspen's operations for the six months ended June 30,

        beginning of that fiscal year.

(2)     Adjustment to depletion expense to record the depletion expense as if
        Aspen had been acquired on July 1, 1996.

(3)     To record imputed interest expense on the $300,000 six month note
        payable issued the sellers of Aspen.

(4)     To record the effect of the pro forma adjustments on the income tax
        benefit.

(5)     To record the net shares issued in the acquisition as if they had been
        issued on July 1, 1996.

                          INDEPENDENT AUDITOR'S REPORT




Board of Directors
Aspen Energy Corporation
Dallas, Texas

We have audited the accompanying balance sheets of Aspen Energy Corporation as
of December 31, 1996, and the related statements of operations and retained
earnings and cash flows for the year then ended.  These financial statements
are the responsibility of the Company's management.  Our responsibility is to
express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Aspen Energy Corporation as of
December 31, 1996, and the results of its operations and its cash flows for the
year then ended, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
           (The period subsequent to December 31, 1996 is unaudited.)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Nature of Operations

    Aspen Energy Corporation (the "Company") is engaged in the acquisition,
    operation and development of oil and gas properties, which are located
    primarily in Texas, Oklahoma and Utah as of December 31, 1996.

    Cash and Cash Equivalents

    The Company considers all highly liquid debt instruments purchased with a
    maturity of three months or less to be cash equivalents.

    Revenue Recognition

    The Company recognizes revenue as oil or gas is produced and sold.

    Oil and Gas Producing Operations

    The Company follows the full cost method of accounting for oil and gas
    properties.  Accordingly, all costs associated with acquisition,
    exploration, and development of oil and gas reserves, including directly
    related overhead costs, are capitalized in the full cost pool.  All
    capitalized costs of oil and gas properties, including the estimated future
    costs to develop proved reserves, are amortized on the unit-of-production
    method using estimates of proved reserves.

    In addition, capitalized costs are subject to a "ceiling test", which
    basically limits such costs to the aggregate of the estimated present
    value, discounted at a 10% interest rate, of future net revenues from
    proved reserves, based on current economic and operating conditions, plus
    the lower of cost or fair market value of unproved properties.

    Sales of proved and unproved properties are accounted for as adjustments of
    capitalized costs with no gain or loss recognized, unless such adjustments
    would significantly alter the relationship between capitalized costs and
    proved reserves of oil and gas, in which case the gain or loss is
    recognized in income.  Abondonments of properties are accounted for as
    adjustments of capitalized costs with no loss recognized.

    Income Taxes

    Income taxes are provided for the tax effects of transactions reported in
    the financial statements and consist of taxes currently due, if any, plus
    net deferred taxes related primarily to differences between the bases of
    assets and liabilities for financial and income tax reporting.  Deferred
    tax assets and liabilities represent the future tax return consequences of
    those differences, which will either be taxable or deductible when the
    assets and liabilities are recovered or settled.  Deferred tax assets
    include recognition of operating losses that are available to offset future
    taxable income and tax credits that are available to offset future income
    taxes.  Valuation allowances are recognized to limit recognition of
    deferred tax assets where appropriate.  Such allowances may be reversed
    when circumstances provide evidence that the deferred tax assets will more
    likely than not be realized.

    Financial Investments

    The Company's financial instruments are cash, accounts receivable and
    payable and loans receivable from related parties.  Management estimates
    that the fair values of these financial instruments approximate their
    carrying values due to their short-term nature.

                         NOTES TO FINANCIAL STATEMENTS
           (The period subsequent to December 31, 1996 is unaudited.)

    Loss Per Share

    Loss per share is computed based on the weighted average number of shares
    outstanding during the period.

    Use of Estimates and Certain Significant Estimates

    The preparation of the Company's financial statements in conformity with
    generally accepted accounting principles requires the Company's management
    to make estimates and assumptions that affect the amounts reported in these
    financial statements and accompanying notes.  Actual results could differ
    from those estimates.  Significant assumptions are required in the
    valuation of proved oil and gas reserves, which as described above may
    affect the amount at which oil and gas properties are recorded.  It is at
    least reasonably possible those estimates could be revised in the near term
    and those revisions could be material.

    Unaudited Information

    The balance sheet as of June 30, 1997 and the statements of operations for
    the six month periods ended June 30, 1997 and 1996 were taken from the
    Company's books and records without audit.  However, in the opinion of
    management, such information includes all adjustments which are necessary
    to properly reflect the financial position of the Company as of June 30,
    1997 and the results of its operations for the six months ended June 30,
    1997 and 1996.

2.  LOANS RECEIVABLE FROM RELATED PARTIES

    The Company had loans receivable from stockholders for cash advances that
    totaled $425,000 and $345,000 at June 30, 1997 and December 31, 1996,
    respectively.  The loans were unsecured, non-interest bearing and contained
    no specific repayment terms.  The loans were subsequently retired as
    described in Note 6, and have been classified as a reduction of
    stockholders' equity in the accompanying balance sheets.

3.  PRODUCTION PAYMENT LIABILITY

    The Company has a liability associated with the purchase of an oil and gas
    property that requires payment to the creditor of 25% of the net revenue
    earned from the property each month.  The liability does not have a stated
    interest rate. Therefore, interest was imputed at 10%.  The balance at June
    30, 1997 and December 31, 1996 is $62,791 and $65,800, respectively.

4.  CONCENTRATION OF CREDIT RISK AND SALES REVENUE

    The Company had the following concentrations in volume of oil and gas sales
    revenue in 1996:

                 --------
                    <S>                  <C>
                    A                     43%
                    B                     29%
                    C                     22%
</TABLE>

    Additionally, the three customers above accounted for a substantial
    majority of accrued oil and gas sales as of December 31, 1996.

    The Company periodically maintains balances in financial institutions in
    excess of FDIC insurance limits.  The Company had a balance in one
    institution at December 31, 1996 that was $276,677 in excess of such limit.

5.  INCOME TAXES

    The Company's income tax benefit of $237,143 for the year ended December
    31, 1996 was composed entirely of deferred taxes.

    The Company's deferred tax liability of $320,514 at December 31, 1996 was
    the result of different bases for book and tax purposes of the Company's
    oil and gas properties.

6.  SUBSEQUENT EVENT

    In 1997, 100% of the Company's stock was sold to Cotton Valley Resources
    Corporation.  In connection with that transaction, the loans receivable
    from related parties (Note 2) were retired.

7.  SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)

    The following table sets forth certain information with respect to the oil

    All of the above reserves were classified as proved undeveloped and are
    located in the continental United States.  The Company has production on
    the property, but intends to convert the property to a waterflood project,
    which would entail conversion of the producing wells to injection wells.
    The Company also has other, relatively minor, producing properties for
    which reserve reports were not prepared.  To develop the Company's reserves
    will require a substantial investment of capital, which is currently not
    available.  Therefore, the Company will either have to raise additional
    capital or sell interests in its property, which would reduce the Company's
    net interest in its reserves.

    Proved oil and gas reserves are the estimated quantities of crude oil,
    condensate and natural gas which geological and engineering data
    demonstrate with reasonable certainty to be recoverable in future years
    from known reservoirs under existing economic and operating conditions.
    Proved developed oil and gas reserves are reserves that can be expected to
    be recovered through existing wells with existing equipment and operating
    methods.  The above estimated net interests in proved reserves are based
    upon subjective engineering judgments and may be affected by the
    limitations inherent in such estimation.  The process of estimating
    reserves is subject to continual revision as additional information becomes
    available as a result of drilling, testing, reservoir studies and
    production history, especially in connection with the Company as all the
    reserves are proved undeveloped.  There can be no assurance that such
    estimates will not be materially revised in subsequent periods.

8.  STANDARDIZED MEASURE OF CHANGES IN FUTURE NET REVENUES (UNAUDITED)

    The standardized measure of discounted future net cash flows at December
    31, 1996, relating to proved oil and gas reserves is set forth below.  The
    assumptions used to compute the standardized measure are those prescribed
    by the Financial Accounting Standards Board and, as such, do not
    necessarily reflect the Company's expectations of actual revenues to be
    derived from those reserves nor their present worth.  The limitations
    inherent in the reserve quantity estimation process are equally applicable
    to the standardized measure computations since these estimates are the
    basis for the valuation process.

Time (as defined below), Aspen will be merged with and into Merger Sub, with
Merger Sub being the surviving corporation in the Merger and becoming a
wholly-owned subsidiary of Buyer, and the separate corporate existence of Aspen
shall cease (the Merger Sub, as the surviving corporation in the Merger being
herein referred to as the "Surviving Corporation").

1.02 Conversion of Securities. At the Effective Time, by virtue of the Merger
and without any action on the part of the Shareholders of any of the shares (the
"Shares") of common stock, no par value per share, of Aspen ("Aspen Common
Stock"), Buyer or Merger Sub;

         (i) The Shares issued and outstanding immediately prior to the
      Effective Time




AGREEMENT AND PLAN OF MERGER, Page 1

                        BUYER COMMON STOCK - RESTRICTIONS

3.01 Unregistered Shares. The shares of Buyer Common Stock to be issued to
Shareholders hereunder will be issued in Canada and will be transferable in
Canada without registration under the



AGREEMENT AND PLAN OF MERGER, Page 3

<PAGE>   4



Canadian securities laws. However, at the time of issuance, the Buyer Common
Stock will not be registered under the Securities Act of 1933 or the securities
acts of any state of the United States of America.

3.02 Investment Representations. In connection with the delivery of the Buyer
Common Stock each Shareholder represents and warrants:

     3.02.01 Shareholder is purchasing the Buyer Common Stock for his own
     account for investment and not with the view to their distribution other
     than in accordance with the Securities Act of 1933, as amended (the "Act"),
     and the rules and regulations promulgated by the United States Securities
     and Exchange Commission thereunder, and with the Canadian Securities laws
     ("Canadian Laws").

     3.02.02 Shareholder understands that the shares of Buyer Common Stock have
     not been registered under the Act, that they must be held indefinitely
     unless they are subsequently registered under the Act or an exemption from
     such registration is available, and, except as set forth herein, Buyer is
     under no obligation to register the shares under the Act or to comply with
     any such exemption.

     3.02.03 Shareholder understands that so long as such action may be
     appropriate for compliance under the Act and Canadian Laws, Buyer may (a)
     place a legend, label, or sticker upon the certificates representing the
     Buyer Common Stock to be acquired by Shareholder referring to the
     investment commitment contained herein, and (b) advise the Transfer Agent
     for the shares (by "stop-transfer" instructions) of the representations and
     agreements contained herein; provided that such "stop-transfer"
     instructions shall not prevent the Shareholders from transferring their
     shares of Buyer Common Stock in Canada.

3.03 Restrictions on Sale. Shareholders agree not to sell, trade, give or
transfer the Buyer Common Stock to be issued to Shareholders pursuant to Section
1.05.02 above, except as specifically provided in this Section 3.03.

September 1, 1997, and continuing the first day of each month thereafter through

certificates evidencing ownership of this agreement shall bear a legend
reflecting this agreement and specifically referring to this Section 3.03 of
this Agreement.

3.04 Registration Statement. Buyer agrees that if at any time Buyer shall
determine to make application to register any of its securities under the Act or
Canadian Laws, it will upon each such determination promptly give written notice
of its intention in that regard to Shareholders. Upon a written request from a
Shareholder, given not more than ten days after receipt of notice from Buyer of
such proposed application, Buyer will endeavor to register under the Act and
Canadian Laws any Buyer Common Stock then held by any of the Shareholders. Buyer
agrees to use its best efforts to the end that each registration of shares
required to be made by Buyer shall become effective as



AGREEMENT AND PLAN OF MERGER, Page 4

<PAGE>   5



promptly as possible and remain effective for as long a period of time as is
practicable.

3.05 Furnishing of Documents. Shareholder shall furnish to each Shareholder such
reasonable number of copies of the registration statement, such prospectuses as
are contained in the registration statement and such other documents as the
Shareholders may reasonably request in order to facilitate the offering of the
shares of Buyer Common Stock.

3.06 Amendments and Supplements. Buyer shall prepare and promptly file with the
Securities and Exchange Commission (the "SEC") and promptly notify the
Shareholders of the filing of such amendments or supplements to each
registration statement or prospectuses contained therein as may be necessary to
correct any statements or omissions if, at the time when a prospectus relating
to the shares of Buyer Common Stock is required to be delivered under the Act,
any event shall have occurred as a result of which any such prospectus or any
other prospectus as then in effect would include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made
not misleading. Buyer shall also advise the Shareholders promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC suspending the effectiveness of the registration statement or the
initiation or threatening of any proceeding for that purpose and promptly use
its reasonable best efforts to prevent the issuance of any stop order or to
obtain its withdrawal if such stop order should be issued.

3.07 Duration. In the event that any registration statement filed by Buyer under
this Article III becomes effective, to the extent permitted by the applicable
law under which such registration statement was filed, Buyer shall use its best
efforts to maintain the effectiveness of the registration statement until such
time as Buyer reasonably determines, based on an opinion of counsel, that all of
the Shareholders will be eligible to sell all of the shares of Buyer Common
Stock then owned by the Shareholders without the need for continued registration
of the shares.

3.08 Indemnification.

     3.08.01 Buyer will indemnify and hold harmless the Shareholders and their
     directors and officers, if applicable, and each person, if any, who
     controls a Shareholder within the meaning of the Act, from and against any
     and all losses, damages, liabilities, costs and expenses to which the
     Shareholders or any such controlling person may become subject under the
     Act or otherwise, insofar as such losses, claims, damages, liabilities,
     costs or expenses are caused by any untrue statement or alleged untrue
     statement of any material fact contained in the registration statement, any
     prospectus contained therein or any amendment or supplement thereto, or
     arise out of or based upon the omission or alleged omission to state
     therein 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; provided, however, that, Shareholder will not be
     liable in any such case to the extent that any such loss, claim, damage,
     liability, cost or expense arises out of or is based upon an untrue
     statement or alleged untrue statement or omission or alleged omission so
     made in conformity with information furnished



AGREEMENT AND PLAN OF MERGER, Page 5

<PAGE>   6



by any Shareholder or such controlling person in writing specifically for use in
the preparation thereof.

3.08.02 Each of the Shareholders severally and not jointly will indemnify and
hold harmless Buyer and each person, if any, who controls Buyer within the
meaning of the Act, from and against any and all losses, damages, liabilities,
costs and expenses to which Buyer or any such controlling person may become
subject under the Act or otherwise, insofar as such losses, damages,
liabilities, costs or expenses are caused by any untrue statement or alleged
untrue statement of any material fact contained in the registration statement,
any prospectus contained therein or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
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, to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was so made in reliance upon and in
strict conformity with written information furnished by or on behalf of any
Shareholder specifically for use in the preparation thereof.

3.08.03 Promptly after receipt by an indemnified party pursuant to the
provisions of Section 3.08.01 or 3.08.02 of notice of the commencement of any
action involving the subject matter of the foregoing indemnity provisions, such
indemnified party will, if a claim thereof is to be made against the
indemnifying party pursuant to the provisions of said Sections, promptly notify
the indemnifying party of the commencement thereof; but the omission to so
notify the indemnifying party will not relieve it from any liability which it
may have hereunder unless the indemnifying party has been materially prejudiced
thereby nor will such failure to so notify the indemnifying party relieve it
from any liability which it may have to any indemnified party otherwise than
hereunder. In case such action is brought against any indemnified party and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party shall have the right to participate in, and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided, however, if the defendants in any action include both the indemnified
party and the indemnifying party and there is a conflict of interest which would
prevent counsel for the indemnifying party from also representing the
indemnified party, the indemnified party or parties shall have the right to
select separate counsel to participate in the defense of such action on behalf
of such indemnified party or parties. After notice from the indemnifying party
to such indemnified party of its election so to assume the defense thereof the
indemnifying party will not be liable to such indemnified party pursuant to the
provisions of said Section 3.08.01 or 3.08.02 for any legal or other expense
subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation, unless (i) the indemnified
party shall have employed counsel in accordance with the provisions of the
preceding sentence, (ii) the indemnifying party shall not have employed counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after the notice of the commencement of the
action, or (iii) the indemnifying party has authorized the employment




AGREEMENT AND PLAN OF MERGER, Page 6
<PAGE>   7



     of counsel for the indemnified party at the expense of the indemnifying
     party.

     3.08.04 In the event any of the shares of Buyer Common Stock are sold by
     any Shareholder or Shareholders in an underwritten public offering
     consented to by Buyer, Buyer shall provide indemnification to the
     underwriters of such offering and any person controlling any such
     underwriter on behalf of the Shareholder or Shareholders making the
     offering all to the extent set forth in Section 3.08; provided, however,
     that Buyer shall not be required to consent to any such underwriting or to
     provide such indemnification in respect to the matters described in the
     proviso to the first sentence of Section 3.08.01.

3.09 Expenses of Registration. Each registration statement hereunder and all
expenses associated therewith shall be at the expense of Buyer; provided,
however, that Buyer shall not be obligated to bear the expense of any
underwriting charges, commissions or fees with respect to the sale of the shares
sold by Shareholders. The rights of registration under this paragraph may not be
assigned without the expressed written consent of Buyer.

     Adverse Effect, or

     it is bound or to which it or the oil and gas leases owned by Aspen may be
     subject except for violations that will not have a Material Adverse Effect.

     thereafter receiving full payment therefor.

     at prices less than determined by reference to market indices. None of the

     quantities and at the price set out in any of the Contracts whether such
     failure or refusal was pursuant to any force majeure, market-out or any
     similar provision contained in any of the Contracts or agreement or
     otherwise.

     future use of any of the Properties or that require any change in the
     present conditions of any of the Properties.

     (c) There are no actions, suits, claims or proceedings seeking money
     damages, injunctive relief, remedial action or other remedy, pending or, to

7.01 Defensible Title.

     7.01.01 For purposes hereof; "Defensible Title" means with respect to the
     Properties such title as (A) will enable Merger Sub, as Aspen's successor,
     to receive payment for production from a particular Lease in an amount not
     less than the "Net Revenue Interest" for the property as set forth on
     Exhibit "C", without reduction, suspension or termination throughout the
     productive life of wells located on the property, (except for any

     proceedings, lack of survey, defects that have been cured by possession
     and failure to record releases of liens, production payments, leases or
     mortgages that have expired by their terms, and other matters which would
     not reasonably be expected to result in claims that will materially and
     adversely affect Aspen's title to the Properties, shall not constitute
     "Title Defects" hereunder.             

     7.01.03 For purposes hereof "Permitted Encumbrances" shall mean (A) liens
     securing payments to mechanics and materialmen, payments of taxes or claims
     arising by statute to secure or protect any other payment obligation that
     are, in each case, not yet delinquent or, if delinquent, are being
     contested in good faith in the normal course of business and which, if

     any municipality or public authority with respect to any franchise, grant,
     certificate, license or permit, and all applicable law; (C) Title Defects
     that Buyer fails to assert in accordance with the provisions of this
     Article VII prior to the Notice Date; (D) consents to assignment by a third

     the Leases that do not unreasonably or materially interfere with the
     operation of the Leases for exploration and production of hydrocarbons or
     related operations; (F) all royalties, overriding royalties, net profits
     interests, production payments, carried interests, reversionary interests,
     calls on production and other burdens on or deductions from the proceeds of
     production that do not operate to (i) reduce the Net Revenue Interest
     ("NRI") in a Lease below that set forth in Exhibit "C" for such Lease or
     (ii) increase the Expense Interest ("WI") in a Lease above that set forth
     in Exhibit "C" for such Lease without a proportionate increase in the NRI
     for such Well; (G) the terms and conditions of the Lease(s); (H) the terms
     and conditions of all production sales contracts, transportation
     agreements, pooling agreements, unitization agreements, operating
     agreements, processing agreements, and all other contracts, agreements and
     instruments related to or utilized in connection with the properties, or
     the production, storage, treatment, transportation, sale or disposal of
     oil, gas or other hydrocarbons, mineral or substances therefrom, to the
     extent such contracts (i) do not reduce the NRI in a Lease below that set
     forth in Exhibit "C" for such Lease, (ii) do not increase the WI in a Lease
     above that set forth in Exhibit "C" for such Lease without a proportionate
     increase in the NRI for such Lease or (iii) are of the type normally
     entered into in the normal course of business by a reasonable, prudent
     owner of similar properties; (I) conventional rights of reassignment prior

     other liens, charges, encumbrances, contracts, agreements, instruments,
     obligations, defects or irregularities of any kind whatsoever affecting the

     Properties.

7.02 Environmental Condition. Buyer shall conduct investigations and inspections
of the physical premises of the Properties as Buyer in its sole discretion may
deem advisable. In the event that Buyer's investigations and inspections
discloses an "Environmental Defect" which shall include the existence of any
hazardous materials, the threatened release of hazardous materials or the
violation or threatened violation of any Federal. State or local statute, rule,
regulation or ordnance relating to protection of the environment. In the event
that Buyer determines that an Environmental Defect exists, Buyer may (i)
terminate this Agreement or (ii) give Shareholders notice of the existence of
the defect and seek to negotiate a reduction of the Purchase Price as provided
in the next section.

7.02 Notice of Title or Environmental Defects. Buyer shall, as soon as possible,
but in no event later than seven (7) days prior to Closing (the "Notice Date"),
give written notice to Shareholders




AGREEMENT AND PLAN OF MERGER, Page 20

and Aspen specifying all Title Defects and Environmental Defects for which Buyer
requests a reduction in the Purchase Price and shall describe each alleged
Defect with reasonable particularity and specify for each Defect the amount of
reduction in the Purchase Price proposed by Buyer (the "Defect Amount"). If
Buyer and Shareholders are unable to reach an agreement as to the amount of
reduction of the Purchase Price for such Defect(s), Buyer will have the option
to (i) close the transaction without a reduction in the Purchase Price in which
case such action shall be deemed a waiver of all Defects on which an agreement
to the reduction in Purchase Price has not been agreed upon, or (ii) terminate
this Agreement. Failure by Buyer to timely assert a Title Defect or
Environmental Defect shall be deemed an election by Buyer to waive such Defect.

7.03 Shareholder's Election to Cure. Shareholders shall have the right to elect
to cause Aspen, at any time prior to Closing, whether or not to cure any
asserted Title Defect or Environmental; however, any curing of a Defect shall be

shall be at the sole cost of Shareholders.

     due to any actual or potential conflicts of interest. No party shall be
     liable for the fees and expenses of more than one separate firm of
     attorneys at any one time for the indemnified party in connection with any
     one legal proceeding or claim or substantially similar related proceedings
     and claims.

     (B) Notwithstanding anything of the contrary in Section A above, the
     indemnified party shall be entitled to reasonable compensation for costs of
     defense, including reasonable attorneys fees, in the event that (i) the
     employment of separate counsel has been authorized by the indemnifying
     party, (ii) the indemnifying party has failed to defend diligently any
     Claims, or (iii) the parties to such action (including any impleaded
     parties) include both parties hereto, and the indemnified party has been
     advised by legal counsel that there may be legal defenses available to it
     which are different from, in addition to or inconsistent with, the legal
     defenses available to the indemnifying party, or that the indemnified
     party's interest may be adverse in whole or in part to the interest of the
     indemnifying party. Neither party shall except with the prior written
     consent of the other, pay, settle or compromise any Claim; provided,
     however, that the indemnifying party may settle, pay or compromise any
     Claim without the consent of the indemnified party if such settlement or
     compromise includes as an unconditional term, the release by the claimant
     or the plaintiff of the indemnified party from all further liability in
     respect to any such Claims.

     (C) If the Claim is of a sort which requires action on the part of the
     owners of the Properties, such as restoration of surface locations, for
     example, the party having knowledge or receiving notice of such Claim shall
     provide the indemnifying party with the appropriate Claim Notice. The
     indemnifying party shall have the option to respond





AGREEMENT AND PLAN OF MERGER, Page 22
<PAGE>   23

     in such manner as it deems prudent to such Claim and shall make all
     decisions and take all action in response to the Claim. Only if the
     indemnifying party fails to timely and reasonably respond to such Claim may
     the indemnified party take such actions as are necessary to respond to the
     Claim.

                                   ARTICLE IX

9.01 Limitation on Liability of Shareholders. Notwithstanding any other
provision of this Agreement or any other agreement, instrument or document, the
liability of all Shareholders, as a group, for all claims made in connection
with this Agreement and the transactions contemplated herein, including, without
limitation, claims made pursuant to Article VIII shall not exceed in the
aggregate $2,250,000 and with respect to each Shareholder shall not exceed such
Shareholder's percentage (as set forth in Section 1.05.03) of $2,250,000. Under
no circumstances shall Buyer or Merger Sub assert, or shall Shareholders have,
any liability in connection with this Agreement and the transactions
contemplated herein for amounts in excess of $2,250,000 in the aggregate and
with respect to each Shareholder shall not exceed such Shareholder's percentage
(as set forth in Section 1.05.03) of $2,250,000. Buyer and Merger Sub
acknowledge that the sole and exclusive remedy available to Buyer and Merger Sub
for any claim or claims relating to this Agreement and the transactions
contemplated herein are (i) the right to terminate this Agreement pursuant to
Section 10.01, and (ii) the right to seek damages for Claims pursuant to Section
8.01, subject to the limitations in this Article IX. Notwithstanding anything in
this Agreement to the contrary, Shareholders will have no liability (for
indemnification or otherwise) with respect to any representation or warranty or
covenant or obligation to be performed and complied with or any other matter of
any kind unless on or before six months after the Closing Shareholders receive
written notice from Buyer of a claim, specifying the factual basis of that claim
in reasonable detail and the amount of liability therefor. Shareholders will
have no liability (for indemnification or otherwise) with respect to the matters
described in Article VIII until the total of all Claims with respect to such
matters for which Shareholders are liable in the aggregate exceeds $25,000, and
then only for the amount by which such Claims exceed $25,000, subject to the
limitations contained in this Article IX. Additionally, notwithstanding any
other provision of the Agreement, the liability of a Shareholder for breach of
his or her representations in Section 4.01 shall be several and not joint and

her obligations under Article VIII by returning shares of Buyer Common Stock
with each share being credited against such liability at the market price on the
date such shares are delivered to Buyer.

9.02 Damage Limitation. Notwithstanding anything to the contrary herein, in no
event shall any party hereunder be liable to the other for any exemplary,
punitive, special, indirect, consequential, remote or speculative damages;
provided, however, that if a party hereto is held liable to a third party for
any of such damages and one party is obligated to indemnity the other party for
the matter that gave rise to such damages pursuant to this Agreement, then the
indemnifying party shall be liable for, and obligated to reimburse the
indemnified party for, such damages, subject to the damage limitations

set forth in Section 9.01.

                                    ARTICLE X

                                   TERMINATION

10.01 Termination of Agreement. This Agreement and the transactions contemplated
hereby may be terminated upon written notice from the party electing to
terminate this Agreement, in the following instances:

     (A) By either Buyer or Aspen if Closing has not occurred (other than
     through the failure of any party seeking to terminate this Agreement or its
     affiliates to fully comply with its obligations hereunder) on or before
     July 31, 1997, or such later date as the parties may agree upon in writing
     (such date being the "Termination Date").

     (B) By either party pursuant to a specific provision of this Agreement
     providing for such termination.

     (C) By Shareholder if the conditions set forth in Section 6.02 are not
     satisfied in all materials respects or waived as of the Termination Date.

     (D) By Buyer if the conditions set forth in Section 6.01 are not satisfied
     in all material respects or waived as of Termination Date.

     (E) At any time by the mutual written agreement of Buyer and Shareholder.

10.02 Effect of Termination. If this Agreement is terminated pursuant to Section
10.01, all further rights and obligations of the parties under this Agreement
will terminate, except that the rights and obligations in Sections 12.10 and
12.11 and this Section 10.02 will survive. The parties acknowledge that,
prior to Closing, the sole and exclusive remedy of any party to this Agreement
with respect to a breach of a representation or warranty contained herein shall
be the right to terminate this Agreement in accordance with and subject to the
provisions of this Article X; provided, however, that a termination of this
Agreement shall not relieve any party hereto from any liability for damages
incurred as a result of a breach by such party of its covenants hereunder
occurring prior to such termination. Each party hereby covenants never to
institute, directly or indirectly, any action or proceeding of any kind against
any other party hereto based on or arising out of, or in any manner related to,
the breach of a representation or warranty contained herein if this Agreement is
terminated pursuant to Section 10.01.

Shares or other transactions contemplated herein. This Agreement may not be

Exhibit hereto which is supplemented or amended as provided in this section
shall for all purposes after the Closing be deemed to be a reference to such
Exhibit as so supplemented or amended.

      IN WITNESS THEREOF, Buyer, Shareholders, Merger Sub and Aspen have duly
executed this Agreement, as of the day and year first above written.
