                      THE PURCHASE AND SALE


          2.1  Transfer to Berry.  In accordance with the provisions of this
Agreement, Tannehill shall transfer and convey the Assets to Berry free and
clear of all liens and encumbrances (other than Permitted Encumbrances)
pursuant to a Grant Deed, Bill of Sale, Assignment of Leases, Rights of Way,
Easements and Contracts (Unrecorded Documents), and Assignment of Leases,
Rights of Way, Easements and Contracts (Recorded Documents) in the forms
of Exhibits 1, 2, 3 and 4, respectively, attached hereto and made a part hereof
(collectively, the "Instruments of Transfer") to be delivered at the Closing
in accordance with the provisions relating to the Closing, and Berry will
acquire such Assets from Tannehill.

          2.2  Purchase by Berry.  Berry, in reliance upon the covenants,
representations, warranties and indemnities of Tannehill contained herein,
hereby agrees to purchase the Assets from Tannehill for the purchase price
(the "Purchase Price") stated in Section 2.3 hereof.

          2.3  Payment of the Purchase Price.  As payment for the transfer and
conveyance of the Assets by Tannehill to Berry, Berry shall deliver to Escrow
for the benefit of Tannehill or its nominees at the Closing, in accordance
with the provisions related to the Closing, a wire transfer with immediately
available funds in the amount of Nine Hundred Thirty Thousand Dollars
($930,000) to an account specified by the Escrow Agent (as herein defined)
prior to the Closing.  The transaction shall be subject to a post-closing
operating adjustment as provided in Section 2.4 hereof ("Operating
Adjustment").  The Operating Adjustment shall not be handled through Escrow.


<PAGE> 5
          2.4  Operating Adjustment.

               a.   October 1, 1996, at 12:01 a.m. shall be considered the
"Effective Date" of this Agreement, and the oil and gas operations included in
the Assets shall be deemed to be for the account of Berry from and after that
date.  The Operating Adjustment will occur after the Closing in an amount equal
to the difference between (i) the value of oil and gas produced by Tannehill
after the Effective Date and (ii) the normal cost of producing oil and gas
after the Effective Date, as determined by Tannehill's customary accounting
method adjusted to reflect only necessary operating revenues and expenses
which would have been credited to or incurred by Berry had this transaction
closed on the Effective Date.  The oil tanks shall be gauged at 12:01 a.m. on
the Effective Date.  The value of oil and gas produced by Tannehill after
the Effective Date shall be the net sales after royalties adjusted for the
change in inventory between the Effective Date and the Closing.  If the value
of the oil and gas produced after the Effective Date is greater than said
cost, then Tannehill shall pay Berry an Operating Adjustment equal to the
amount of the difference.  If the value of the oil and gas produced after
the Effective Date is less than said cost, then Berry shall pay Tannehill an
Operating Adjustment equal to the amount of the difference.

               b.   In the event Tannehill does not provide Berry with its
calculation of the Operating Adjustment (the "Calculation") prior to the
Closing, Tannehill shall provide Berry with the Calculation within sixty (60)
days after the Closing.  Berry shall have immediate access at reasonable times
to such books, records and invoices of Tannehill as it deems necessary to
verify the Calculation.  If Berry does not object to the Calculation within ten
(10) days after receipt thereof by Berry, it shall be deemed to be final and
binding upon the parties hereto.  If Berry objects to the Calculation within
such ten (10) days by specifying the items to which it objects, then the
parties will attempt to mutually resolve any differences.  If the differences
cannot be resolved within twenty (20) days after Berry's objection to the
Calculation, then all amounts agreed to shall be paid as provided below and
the difference shall be resolved by arbitration under the Commercial
Arbitration rules of the American Arbitration Association.  The costs of
arbitration shall be shared equally by the parties.  This Section 2.4 is the
only Section or part of this Agreement which is subject to arbitration
jurisdiction.

               c.   Within three (3) days of the final determination of the
Calculation, the party required to make the Operating Adjustment payment shall
pay, via wire if requested, the Operating Adjustment payment agreed upon to
the other party.

               d.   For managing Tannehill subsequent to September 30, 1996,
Tannehill shall only be entitled to be credited for management fees at the rate
of Ten Dollars ($10) per day and shall not be entitled to reimbursement of
overhead costs for legal expenses, accounting costs, loan fees and interest,
contributions, dues and assessments, 401K retirement costs or excessive travel
or entertainment costs or expenses.

          2.5  Assets to be Conveyed to Berry.  The Assets to be conveyed to

(the "Tannehill Disclosure Letter"); and (c) all equipment and supplies related
to or utilized in operating the oil properties and facilities owned and/or
operated by Tannehill as described in the Tannehill Disclosure Letter.  Any
asset of Tannehill not described in the Instruments of Transfer or the
Tannehill Disclosure Letter shall be conveyed to Berry subject to Berry's
right, in its sole discretion, to refuse to accept such asset by written
notice to Tannehill within thirty (30) days after Berry receives written
notice from Tannehill that the asset is included in the Assets.

          2.6  Allocation of Purchase Price.  The parties agree to allocate the
Purchase Price for the Assets acquired in accordance with the terms of Code
Section 1060 and the Treasury Regulations promulgated thereunder, and to report

agreed-upon allocation in the form of Exhibit 5 attached hereto and made a part

          2.8  Proration of Credits and Payment Obligations.  All credits and
payment obligations associated with the Assets, including but not limited to

prorated between Tannehill and Berry as of the Effective Date.  Tannehill shall
be responsible and shall pay for all such items due, incurred or attributable
to the period prior to the Effective Date and Berry shall be responsible and
shall pay for all such items due, incurred or attributable to the period after
such date.

          2.9  Real Estate and Other Taxes.  All real estate, occupation, ad
valorem, personal property and severance taxes and charges on any of the Assets
shall be prorated as of the Effective Date.  Tannehill shall pay all such items
for all periods prior to such date, however, Berry shall be entitled to all
refunds and rebates with regard to such periods.  In the event Berry pays
additional taxes or charges which are assessed upon or levied against any of
the Assets after the Closing with respect to any period prior to the Effective
Date, Tannehill shall promptly reimburse Berry the amount thereof upon
presentation of a receipt therefor.  If Tannehill elects to challenge the

                            ARTICLE V
                      COVENANTS OF TANNEHILL


          From and after the date of this Agreement until the Closing, except
as expressly authorized by this Agreement or expressly consented to in writing
by Berry, Tannehill covenants and agrees with Berry as follows:

          5.1  Access to Tannehill.  Tannehill shall afford to Berry and to the
employees, agents, lenders, investors and authorized representatives of Berry
and to their respective counsel and accountants such reasonable access to the
Assets, officers, offices, equipment, files, agreements, documents, and books
and records of Tannehill (including, without


<PAGE> 17
limitation, engineering data and information, computer programs, tapes and
other records), and the opportunity to make notes, abstracts and copies
therefrom, as may be requested by Berry in order that Berry may have full
opportunity to make such reasonable investigations as it shall desire with
respect to the business, operations, Assets and affairs of Tannehill in
connection with the transactions contemplated hereby and Tannehill shall
furnish Berry with such additional financial and operating data and other
information as to the business, operations and Assets of Tannehill as Berry
shall, from time to time, reasonably request for such purpose.  Berry hereby
releases Tannehill from all liability arising out of the entry by Berry or
its employees, agents, lenders, investors or authorized representatives onto
the business premises of Tannehill for purposes of conducting the investigation
contemplated by this Section 5.1.  Berry hereby agrees to indemnify, defend
and hold harmless Tannehill against all liability, demands, claims, costs,
losses, damages, recoveries, settlements and expenses incurred by Tannehill
arising from or related to the conduct by Berry or its employees, agents,
lenders, investors or authorized representatives of the investigation.

          5.2  Governmental Approvals; Consents.

               a.   Tannehill shall use its best efforts, and shall cooperate
with Berry, to obtain all permits, approvals and consents, and to make all
filings, necessary or required to be obtained or made, and to begin and cause
all waiting periods required to lapse, for Berry to have full use and
enjoyment of the Assets subsequent to the purchase and sale and for the
consummation by Tannehill of the transactions contemplated by this Agreement
under any applicable federal law or the applicable laws of any state having
jurisdiction over the transactions contemplated hereby (all such permits,
approvals, filings and consents and the lapse of all such waiting periods
being referred to as the "Requisite Regulatory Approvals").

               b.   Tannehill shall use its best efforts to obtain all
consents, approvals, clearances, waivers, orders or authorizations of any
Person necessary to be obtained by Tannehill for Berry to have full use and
enjoyment of the Assets subsequent to the purchase and sale and for the
consummation of the transactions by Tannehill contemplated by this Agreement.

          5.3  Litigation and Claims.  Tannehill shall promptly inform Berry in
writing of any litigation, or of any claim or controversy or contingent
liability of which Tannehill becomes aware that might reasonably be expected
to become the subject of litigation, against Tannehill or affecting any of
the Assets.

          5.4  Notice of Changes.  Tannehill shall promptly inform Berry in
writing if Tannehill becomes aware of any change that shall have occurred or
that shall have been threatened (or any development that shall have occurred
or that shall have been threatened involving a prospective change) in the
financial condition, results of operations, business of the Assets or of
Tannehill that is or with the exercise of reasonable business judgment would be
expected to have an adverse effect on the Assets.  Tannehill shall promptly
inform Berry in writing if any representation or warranty made by Tannehill in
this Agreement shall cease to be accurate or upon the occurrence of any breach
of any covenant or other agreement required by this Agreement to be performed
or complied with by Tannehill.



<PAGE> 18
          5.5  Conduct of Business Operations.  Tannehill shall not, without
the prior written consent of Berry:

               a.   Other than in the ordinary course of business, sell, lease
or otherwise dispose of any Assets or any interests therein, or enter into, or
consent to the entering into of, any agreement granting to any third Person
a right to purchase, lease or otherwise acquire any Assets or interests
therein, except as otherwise provided for in this Agreement;

               b.   Enter into any agreement or incur any obligation, the terms
of which would be violated by the consummation of the transactions contemplated
by this Agreement;

               c.   (i) Enter into any new line of business with respect to the
Assets; (ii) change its investment, liability management and other material
policies in any respect; (iii) incur or commit to any capital expenditures or
financing; (iv) waive any right under or cancel any contract, debt or claim
listed in any exhibits hereto or the Tannehill Disclosure Letter, which waiver
or cancellation would have an adverse effect on the Assets;

               d.   Enter into any contract, commitment or arrangement to
amend, modify, supplement or otherwise alter the terms of any existing
contract, agreement or instrument attached to the Tannehill Disclosure Letter
with any Person;

               e.   Maintain its books of account other than in the usual,
regular and ordinary manner in accordance with good business practices or make
any change in any of its accounting methods or practices; or 

               f.   Take any action that would or might reasonably be expected
to result in any of the conditions to Closing set forth in Article VII hereof
not being satisfied.

               g.   From the Effective Date to the Closing, fail to use its
best efforts to maintain the daily production over any calendar week during the
period below the average historical daily production from the Section 32
Property.

          5.6  Maintain Assets and Operations.  During the period from the date
hereof through the Closing, Tannehill shall (a) carry on its business in the
usual, regular and ordinary course in a good and diligent manner consistent
with sound business practices and in compliance with all applicable laws, rules
and regulations; (b) not introduce any new method of management or operation;
(c) preserve in full force and effect all leases, operating agreements,
easements, rights of way, permits, licenses, contracts and other agreements
which relate to the Assets (other than those expiring by their terms); (d) use
its best efforts to perform or cause to be performed all of its obligations in
or under any of such leases, agreements and contracts to be transferred to
Berry hereunder; (e) use its best efforts to safeguard and maintain secure all
reports and other confidential data in the possession of Tannehill relating to
the Assets; and (f) use its best efforts to operate its business and activities
in the same manner as they have been carried out and to


<PAGE> 19
maintain the same level  of expenditure as have previously been incurred in
connection with such business and activities.

          5.7  Exclusive Dealing.  Tannehill shall not directly or indirectly,
through any representative or otherwise, solicit or entertain offers from,
negotiate with or in any manner encourage, discuss, accept or consider any
proposal of any Person relating to the acquisition of the Assets or business,
in whole or in part, of Tannehill, whether through direct purchase,
consolidation or other business combination (other than sales of inventory or
in the ordinary course of business) so long as this Agreement has not been
terminated.  Tannehill recognizes that Berry has and continues to incur
substantial time and expense in evaluating this transaction.  Tannehill
acknowledges that Berry, in reliance on this Section 5.7, will continue to
incur additional time, effort and expense.  Tannehill has agreed to this
provision due to the unique terms specified in the AIP and contemplated in this
transaction.

          5.8  Termination Fee.  In the event that Tannehill breaches Section
5.7 hereof and within twelve (12) months after such breach or termination,
Tannehill closes a transaction with an unrelated third party relating to the
acquisition of a Material portion of the Assets or the business of Tannehill,
in whole or part, whether through direct purchase, merger, consolidation or
other business combination (other than sales of inventory or immaterial
portions of Tannehill's Assets in the ordinary course), then, immediately upon
such closing, Tannehill shall pay to Berry the sum of One Hundred Thousand
Dollars ($100,000).  Such payment shall constitute liquidated damages and, in
the absence of fraud or bad faith, shall be in lieu of any other penalty or
remedy Berry might otherwise seek, the parties having determined that the


<PAGE> 20
actual damages resulting from the events for which such liquidated damages are
to be awarded would be extremely difficult and uncertain to calculate and that
liquidated damages above represent a good faith estimate of such actual
damages.

                        COVENANTS OF BERRY


          Berry hereby covenants and agrees with Tannehill as follows:

          6.1  Cooperation.  Subject to the terms and conditions of this

Act"), and listed company under the New York Stock Exchange (the "NYSE"), is
required to comply with certain disclosure requirements regarding its business
activities, including, but not limited to, the issuance of press releases and
the preparation and filing of periodic reports with the Securities and
Exchange Commission.  In order to comply with the disclosure requirements of
the Exchange Act and NYSE, as well as the timing of such disclosures, all
statements to the public, including press releases, shall be at the sole
discretion of Berry.

duly performed and complied in all respects with the covenants, agreements and
conditions required by this Agreement to be performed or complied with by it

be continuing.

          7.3  Consents.  Any consent required for the consummation of this
purchase and sale under any agreement, contract, license or other instrument
described in any exhibit hereto or referred to herein, or for the continued
enjoyment by Berry of any benefits of such agreement, contract, license or

obligated to obtain pursuant to this Agreement, shall have been obtained and
be effective.

          7.4  Governmental Approvals.  All Requisite Regulatory Approvals
shall have been obtained, made or lapsed and shall be in full force and effect.

          7.5  Approval of Counsel.  The form and substance of all legal

reasonably acceptable to Nordman, Cormany, Hair & Compton, counsel to Berry.

          7.6  Officers' Certificate.  Berry shall have received a certificate
of Tannehill, substantially in the form of Exhibit 8 attached hereto and made a
part hereof, satisfactory in form and substance to Berry, executed on behalf
of Tannehill by its President and Secretary, as to compliance with the matters
set forth in Sections 7.1, 7.2, 7.3 and 7.4 of this Agreement.

          7.7  Resolutions.  Berry shall have received certified copies of
Resolutions of the Board of Directors of Tannehill and the written consent of
the Shareholders owning one hundred percent (100%) of the outstanding shares
of common stock of Tannehill approving this Agreement, and the transactions
contemplated hereby.

          7.8  Opinion of Counsel.  Berry shall have received the opinion of
Roger Coley, counsel to Tannehill and the Shareholders, in form and content
satisfactory to Berry, substantially in the form of Exhibit 9 attached
hereto and made a part hereof.


<PAGE> 22
          7.9  Closing of Agreements.  The Closing shall not occur unless the
Closings contemplated by the Partnership Purchase Agreement and the TEC
Purchase Agreement have occurred or will occur concurrently with the Closing. 

          7.10 Condition of Section 32 Property.  Berry shall have approved
title to and the condition of the Section 32 Property as follows:

               a.   A current CLTA Preliminary Title Report prepared by First
American Title Company covering the Section 32 Property, accompanied by legible
copies of all documents referred to as exceptions in the report to the extent
reasonably available through Tannehill's best efforts and a map plotting all
easements (the "PTR"), has been delivered to Berry by Tannehill.

               b.   If Berry elects to obtain an ALTA Policy, a survey of the
Section 32 Property shall have been prepared, at Berry's expense, by a licensed
surveyor or registered civil engineer, in sufficient detail to provide for the
policy of title insurance to be purchased by Berry, certified to Berry in a
form satisfactory to Berry, without boundary, encroachment or survey exceptions
and which shows the location of all easements and improvements.  It shall
be Berry's sole responsibility to obtain such survey by the Title Approval
Date defined below.  Berry's failure to do so will be deemed Berry's waiver of
this condition.  If Berry does not elect to obtain an ALTA Policy, then
Tannehill shall provide Berry with a CLTA Policy at Tannehill's expense.

               c.   Title shall be free of Encumbrances not approved by Berry.
On or before November 8, 1996 (the "Title Approval Date"), Berry shall advise
Tannehill in writing of what exceptions to coverage, if any, are unacceptable
to Berry (the "Title Disapproval Notice").  Notwithstanding any other provision
of this Section 7.10, Berry hereby objects to all monetary Encumbrances, which
monetary Encumbrances (if any) Tannehill shall cause to be eliminated at the
Closing except for non-delinquent real property taxes and assessments, which
shall be one of the exceptions to coverage.  Tannehill shall have ten (10)
business days after receipt of a Title Disapproval Notice to give Berry
notice either:  (i) that Tannehill will remove, on or before the Closing, any
disapproved exceptions to coverage and provide Berry with evidence satisfactory
to Berry of such removal; or (ii) that Tannehill elects not to cause such
exceptions to coverage to be removed, in which case Berry shall have five (5)
business days thereafter to notify Tannehill in writing of Berry's election
(a) to waive any objectionable exceptions and to proceed with the purchase of
and to take the Section 32 Property subject to such exceptions, but otherwise
pursuant to the terms of this Agreement, or (b) to terminate this Agreement.
If Berry shall fail to give Tannehill notice of such election within said five
(5) business days, Berry shall be deemed to have elected to waive its objection
to the coverage and to proceed with this purchase.  In the event that during
escrow any amended or supplemented PTR is issued disclosing new exceptions to
coverage, Berry shall again have the right to give a Title Disapproval Notice
as to such new exception, in which case all the foregoing rights of the parties
following the giving of such a notice shall again apply as stated above.



<PAGE> 23
               d.   Berry shall not have given written notice of disapproval of
matters related to the Section 32 Property.  Berry's failure to give written
notice of disapproval on or before November 8, 1996 (the "Property Approval
Date") of all aspects and matters related to the Section 32 Property, including
size, shape, configuration, access, easements (express, implied and by
prescription), geologic/subsidence and soil conditions, hydrologic conditions,
water supply quantity and quality, buildings, tanks, pipelines, oil and gas
wells, oils and gas surface equipment, and the condition of all other fixed
equipment shall be deemed to be approved.  To facilitate Berry's review,
Tannehill shall deliver to Berry within fifteen (15) business days after the
date of this Agreement, (i) any environmental reports prepared by or for
Tannehill covering all or any portion of the Section 32 Property, without
representation or warranty as to their accuracy or validity; (ii) copies of
any service contracts now in effect, all of which are cancelable at any time,
or by the giving of not more than thirty (30) days' notice; and (iii) any well
logs and reports of water usage made to the Regional Water Quality Control
Board, the Division of Oil, Gas and Geothermal Resources and other agencies,
as applicable.

               e.   Berry shall be satisfied that there are no Hazardous
Materials, as that term is defined by all or any applicable laws, on the
Section 32 Property or in the groundwater thereunder and Berry's acceptance and
approval of an Environmental Audit and Assessment ("Phase I Report") as to the
Section 32 Property performed at Berry's direction and sole cost and expense.
Berry's failure to give notice of disapproval of the Phase I Report obtained
by Berry, if any, on or before the Property Approval Date shall be deemed as
Berry's approval thereof and acceptance of the Section 32 Property in its
present condition.  In the event such Phase I Report or any Phase II Report
involving soil and/or groundwater tests, approved in advance by Tannehill,
discloses that the Section 32 Property or groundwater thereunder is
contaminated with Hazardous Materials in quantities requiring remediation or
removal under existing law, Berry shall have the right to terminate this
Agreement.  Except as provided in the succeeding sentence, Berry agrees that
the Phase I Report and any other report, tests, and information and conclusions
stated therein shall be kept confidential and that any reporting requirements
to any governmental agency or any other third party arising therefrom shall be
the sole responsibility of Tannehill.  Notwithstanding the foregoing, in the
event that any then applicable law, statute or ordinance requires Berry to
report or disclose the Report or Report findings to a governmental agency, then
and only then shall Berry disclose the Report findings.  In no event shall
Berry be entitled to conduct any soil borings or groundwater tests without
Tannehill's prior written approval, which may be conditioned or denied in
Tannehill's sole discretion.

               f.   Berry shall have received an affidavit, certification or
notice required by Section 1445 of the Code and the Regulations pursuant
thereto.  In addition, Tannehill shall have provided Berry with the
certification required to show that withholding is not required pursuant to
California Revenue and Taxation Code Section 18662(e).

          7.11 Good Standing Certificates.  Tannehill shall have delivered
valid Good Standing Certificates from the Secretary of State of California and
the California Franchise Tax Board showing Tannehill in good standing.

                            ARTICLE IX
                   TERMINATION PRIOR TO CLOSING


          9.1  Termination.  This Agreement may be terminated at any time prior
to the Closing:

               a.   By the mutual written consent of Berry and Tannehill;

               b.   Subject to the right of either party to extend the Closing

               c.   By Berry in writing if Tannehill or the Shareholders shall

except for the obligation under Sections 3.12 and 4.5; provided, however, that
termination pursuant to paragraphs 9.1c or d hereof shall not relieve any
defaulting party from any liability to the other parties hereto.


                            ARTICLE X
                         INDEMNIFICATION


          10.1 Indemnification by Berry.  Berry agrees to indemnify, defend and
hold Tannehill, and agents of Tannehill, harmless from and against any and all
loss, liability, damage, costs and expenses (including interest, penalties,
settlements, fines, costs and expenses incurred in connection with
investigating and defending any claims or causes of action, and reasonable
attorneys' fees) that Tannehill and its agents may incur or become subject to
arising out of or due to any inaccuracy of any representation or the breach of
any warranty, covenant, undertaking or other agreement of Berry contained in
this Agreement.

          10.2 Indemnification by Tannehill and the Shareholders.  Tannehill
and the Shareholders, jointly and severally, agree to indemnify, defend and
hold Berry, and the officers,


<PAGE> 26
directors, employees and agents of Berry (collectively, the officers,
directors, employees and agents being referred to in each case as its
"Related Parties") harmless from and against any and all lawsuits, liability,
damage, costs and expenses (including interest, penalties, settlements, fines,
costs and expenses incurred in connection with investigating and defending
any claims or causes of action, and reasonable attorneys' fees) that Berry and
its Related Parties may incur or become subject to arising out of or due to any
inaccuracy of any representation or the breach of any warranty, covenant,
undertaking or other agreement of Tannehill or the Shareholders contained in
this Agreement.  Tannehill and the Shareholders also jointly and severally
agree to indemnify, defend and hold Berry, and the Related Parties, harmless
from any and all lawsuits, liability, damage, cost and expenses (including
interest, penalties, settlements, fines, costs and expenses incurred in
connection with investigating and defending any claims or causes of action and
reasonable attorneys' fees) that Berry and its Related Parties may incur or
become subject to arising out of or due to the actions of Baker Chemical or the
Baker Litigation or attributable to environmental conditions created directly
or indirectly by or as a result of the actions of Baker Chemical and/or its
employees, officers and agents.

          10.3 Survival.  The several warranties, indemnities, representations,
covenants and agreements of the parties contained in this Agreement and in any
other instrument delivered pursuant hereto shall survive the Closing and shall
remain in full force and effect thereafter.

          10.4 Notice and Opportunity to Defend.

               a.   If a party seeking indemnification (the "Indemnitee")
becomes aware of any matters that it believes may give rise to an
indemnifiable claim, or asserts any claim that it believes may be indemnifiable
pursuant to this Agreement, the Indemnitee shall give the party obligated to
provide indemnification (the "Indemnifying Party") prompt written notice of
such matter or claim, stating with particularity the nature of such matter or
the aforementioned claim and the amount thereof.  Failure to provide such
notice shall not affect the right of the Indemnitee to indemnification
except to the extent such failure shall have resulted in liability to the
Indemnifying Party that could have been actually avoided had such notice been
provided within such required time period.

               b.   If the matter that the Indemnitee believes gives rise to an
indemnifiable claim does not involve a third party claim against an Indemnitee,
the Indemnifying Party shall have thirty (30) days from the date on which it
received notice of such claim pursuant to this Section to respond to such
notice.  If such Indemnifying Party accepts responsibility or does not respond
within such thirty (30)-day period, the Indemnifying Party shall promptly pay
to the Indemnitee the full amount of such claim.  If the Indemnifying Party
rejects any liability with respect to such claim, it shall give written notice
of such objection to the Indemnitee within such thirty (30)-day period and the
parties shall seek to resolve such claim by agreement.  If the parties are
unable to resolve such claim by agreement within sixty (60) days following the
expiration of such thirty (30)-day period mentioned above, the parties shall be
entitled to pursue, without prejudice to any of their rights hereunder, such
remedies as may be available to the parties under applicable law.



<PAGE> 27
               c.   In the event any action, suit, proceeding or investigation
is brought against the Indemnitee by a third party which the Indemnitee
believes may give rise to an indemnifiable claim, the Indemnitee shall give
the Indemnifying Party prompt written notice of the commencement of such
action, suit, proceeding or investigation as provided in paragraph a. of this
Section.  Such Indemnifying Party shall have a period of thirty (30) days after
receipt of such notice within which to respond to such notice.  If such
Indemnifying Party does not respond within such thirty (30)-day period or
rejects responsibility for such matter in whole or in part, the Indemnitee
shall be free to pursue, without prejudice to any of its rights hereunder,
such remedies as may be available to such party under applicable law.  If such
Indemnifying Party accepts responsibility, such Indemnifying Party shall, as
between the Indemnitee and the Indemnifying Party, be obligated to compromise
or defend such matter, at its own expense.  The Indemnitee shall employ counsel
of its choice and the Indemnifying Party shall reimburse the Indemnitee for
attorneys' fees and costs.  The Indemnifying Party shall cooperate fully with
the Indemnitee and its counsel in the defense against any such asserted
liability.  Any compromise of such asserted liability by the Indemnitee shall
require the prior written consent of the Indemnifying Party, which shall not
be unreasonably withheld.  If, however, the Indemnitee refuses its consent to a
bona fide offer of settlement that involves solely the payment of cash that the
Indemnifying Party wishes to accept, the Indemnitee may continue to pursue such
matter, free of any participation by the Indemnifying Party, at the sole
expense of the Indemnitee.  In such event, the obligation of the Indemnifying
Party to the Indemnitee shall be equal to the lesser of (i) the amount of the
offer of settlement that the Indemnitee refused to accept plus the costs and
expenses of the Indemnitee prior to the date the Indemnifying Party notified
the Indemnitee of the offer of settlement; and (ii) the actual out-of-pocket
amount the Indemnitee is obligated to pay as a result of such party's
continuing to pursue such matter.  An Indemnifying Party shall be entitled to
recover from the Indemnitee any additional expenses incurred by such
Indemnifying Party as a result of the decision of the Indemnitee to pursue such
matter.

          10.5 General.  The indemnification provided in this Agreement shall
apply regardless of whether the matter subject to indemnification involved an
action taken or omitted that was negligent, grossly negligent or reckless by
the Person to be so indemnified.  It is understood that such indemnification is
intended to be a means of compensating the parties for any damage or liability
directly or indirectly realized by them for matters subject to such
indemnification.  To the extent the indemnification provided for herein may not
be provided to any Person under law, such indemnification shall be required to
be provided to any other Person for whom such indemnification may be
permissible as herein provided.


                            ARTICLE XI
                          MISCELLANEOUS

provision of this Agreement is invalid, illegal or incapable of being enforced
by any rule of law, or public policy, all other conditions and provisions of
this Agreement shall nevertheless remain in full force and effect so long as

affected in any manner materially adverse to any party.  Upon such
determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner to the end that transactions
contemplated hereby are fulfilled to the extent possible.

          11.6 Attorneys' Fees.  In the event of any claim, dispute or
controversy arising out of or relating to this Agreement, including an action
for declaratory relief, the prevailing party in such action or proceeding shall
be entitled to recover its taxable costs or arbitration fees, and reasonable
out-of-pocket expenses, including, but not limited to, telephone calls,
photocopies, expert witnesses, travel, computer expenses related to litigation,
and attorneys' fees to be fixed by the court or the arbitrator.  Such recovery
shall include court costs, out-of-pocket expenses and attorneys' fees on
appeal, if any.  The court shall determine who is the "prevailing party,"
whether or not the dispute or controversy proceeds to final judgment.

     Re:  Berry Petroleum Company / Tannehill Oil Company, Inc.
          Asset Purchase and Sale Transaction

Gentlemen:

     We have acted as counsel to Tannehill Oil Company, Inc., a California
corporation ("Tannehill"), in connection with the purchase of substantially
all the assets of Tannehill by Berry Petroleum Company, a Delaware corporation
("Berry"), pursuant to that certain Purchase and Sale Agreement, dated November
8, 1996, by and between Tannehill and Berry (the "Agreement").

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Berry.

     Based on the foregoing, and in reliance thereon, but subject to the
qualifications herein set forth, we are of the opinion that:

     1.   Tannehill is a corporation duly organized and validly existing under,
and by virtue of, the laws of the State of California and is in good standing
under such laws.  Tannehill has requisite corporate power to own and operate
its properties and assets, and to carry on its business as presently conducted.

     2.   Tannehill has full corporate power and authority to execute and
deliver the Agreement and to perform its obligations under the terms of the
Agreement.

     3.   All corporate action on the part of Tannehill and its directors
and shareholders necessary for the authorization, execution, delivery and
performance of the Agreement and the consummation of the transactions
contemplated thereby has been taken.


<PAGE> 2
The Agreement has been duly executed and delivered by Tannehill and constitutes
a legal, valid and binding obligation of Tannehill, enforceable against it in
accordance with its respective terms, except as such enforceability may be
limited by or subject to (a) any bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to creditor's rights generally and
(b) general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

     4.   The individuals and entities executing the Agreement as shareholders
of Tannehill are the beneficial owners of all the issued and outstanding shares
of Tannehill common stock (the "Shares").  There are no outstanding options,
warrants, rights of first refusal, or other rights calling for the issuance
of, or any security convertible into or exchangeable for, the Shares and no
other person or entity has any right in or to the Shares.

     5.   No consent, approval or authorization of or designation of Tannehill
is required in connection with the valid execution and delivery of the
Agreement, or the consummation of the transactions contemplated thereby on the
Closing thereof, except as such have been obtained or made prior to or upon the
date hereof.

     6.   To our best knowledge, no default exists and no event has occurred
which would constitute a default under, or violation in the due performance and
observance of any term, covenant or condition, or breach of, Tannehill's
Articles of Incorporation or Bylaws or any indenture, license, lease,
franchise, mortgage, instrument, or other agreement to which Tannehill is a
party, or by which it or its properties may be bound; or (a) an event that
would permit any party to any agreement or instrument to terminate it or to
accelerate the maturity of any indebtedness or other obligation of Tannehill;
(b) an event that would result in the creation or imposition of any lien,
charge, or encumbrance on any asset of Tannehill; or (c) an event that would
conflict with any order, rule, or regulation directed to Tannehill by any
court or governmental agency or body having jurisdiction over it.

     7.   Except as disclosed in the Tannehill Disclosure Letter (as defined in
the Agreement), to our best knowledge, there is no suit, action, arbitration,
or legal, administrative, or other proceeding or governmental investigation
pending or threatened against or affecting Tannehill or any of its businesses
or properties or financial or other condition.

     8.   Except as disclosed in the Tannehill Disclosure Letter, there are no
agreements, written or oral, between Tannehill and any other party that affect,
directly or indirectly, the Assets.

     We are members of the bar of the State of California, and accordingly we
do not purport to be experts on, or to be qualified to express any opinion
herein concerning, nor do we express any opinions herein concerning, any law
other than Federal law and the laws of the State of California.

     This opinion letter is limited to the matters expressly stated herein and
no opinion or other statement may be inferred or implied beyond the matters
expressly stated herein.  This


<PAGE> 3
opinion letter is addressed to Berry for the benefit of Berry and is only for
Berry's use in connection with the Agreement.  This opinion letter may not be

This opinion is as of this date, and we expressly decline any undertaking to
advise you of any matters arising subsequent to the date hereof which would

                              Very truly yours,

     Re:  Berry Petroleum Company / Tannehill Oil Company, Inc.
          Asset Purchase and Sale Transaction

Gentlemen:

     We have acted as counsel to Berry Petroleum Company, a Delaware
corporation ("Berry"), in connection with the purchase of substantially all the
assets of Tannehill Oil Company, Inc., a California corporation ("Tannehill"),
by Berry, pursuant to that certain Purchase and Sale Agreement, dated November
8, 1996, by and between Tannehill and Berry (the "Agreement").

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Tannehill.

     1.   Berry is a corporation duly organized and validly existing under, and
by virtue of, the laws of the State of Delaware and is in good standing under
such laws.  Berry has requisite corporate power to own and operate its
properties and assets, and to carry on its business as presently conducted.

     2.   Berry has full corporate power and authority to execute and deliver
the Agreement and to perform its obligations under the terms of the Agreement.

     3.   All corporate action on the part of Berry necessary for the
authorization, execution, delivery and performance of the Agreement and the
consummation of the transactions contemplated thereby, has been taken.  The
Agreement has been duly executed and delivered by Berry and constitutes a
legal, valid and binding obligation of Berry, enforceable against it in
accordance with its respective terms, except as such enforceability may be
limited by or subject


<PAGE> 2
to (a) any bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to creditor's rights generally and (b) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

     4.   No consent, approval or authorization of or designation of Berry is
required in connection with the valid execution and delivery of the Agreement
by Berry, or the consummation by Berry of the transactions contemplated thereby
on the Closing thereof, except as such have been obtained or made prior to or
upon the date hereof.

     5.   To our best knowledge, there is no suit, action, arbitration, or
legal, administrative, or other proceeding or governmental investigation that
is material to the transactions contemplated by this Agreement, pending or
threatened against or affecting Berry or any of its businesses or properties
or financial or other condition.

     We are members of the bar of the State of California, and except for our
opinion set forth in Paragraph 1 above, we do not purport to be experts on, or
to be qualified to express any opinion herein concerning, nor do we express any

          2.1  Transfer to Berry.  In accordance with the provisions of this
Agreement, Tannehill shall transfer and convey the Cogeneration Assets to Berry
free and clear of liens and Encumbrances (other than Permitted Encumbrances)
pursuant to Assignments of Leases, Rights of Way, Easements and Contracts in
the forms of Exhibits 2A and 2B attached hereto and made a part hereof (the
"Instruments of Transfer"), to be delivered at the Closing, in accordance with
the provisions relating to the Closing, and Berry will acquire the Cogeneration
Assets from Tannehill.

          2.2  Purchase by Berry.  Berry, in reliance upon the covenants,
representations, warranties and indemnities of Tannehill contained herein,
hereby agrees to purchase the Cogeneration Assets from Tannehill for the
purchase price (the "Purchase Price") stated in Section 2.3 hereof.

          2.3  Payment of the Purchase Price.  As payment for the transfer and
conveyance of the Cogeneration Assets by Tannehill to Berry, Berry shall
deliver to Escrow for


<PAGE> 6
the benefit of Tannehill or its nominees at the Closing, in accordance with the
provisions related to the Closing, a wire transfer with immediately available
funds in the amount of Two Hundred Thousand Dollars ($200,000) to an account
specified by the Escrow Agent (as herein defined) prior to the Closing.  The
transaction shall be subject to post-closing operating adjustment as provided
in Section 2.4 hereof ("Operating Adjustment").  The Operating Adjustment shall
not be handled through Escrow.

          2.4  Operating Adjustment.

               a.   October 1, 1996, at 12:01 a.m. shall be considered the
"Effective Date" of this Agreement, and the operations of Tannehill and the
Cogeneration Assets, including income derived from the P.G.&E. S.O. #2 Contract,
shall be for the account of Berry from and after that date, conducted in the
ordinary course of business as described in Section 5.5 hereof; provided,
however, that the application of such an Effective Date shall not be deemed to
make Berry liable for any costs or charges related to the SOCAL Contract.  For
all other purposes, and without limiting the generality of the foregoing, the
representations, warranties, covenants and indemnities herein, and the delivery
of the Purchase Price, shall occur and be effective at the Closing.  The
Operating Adjustment will occur at or after the Closing with a cash payment in
an amount equal to the net income or loss of the Cogeneration Assets after the
Effective Date, adjusted to reflect only necessary operating revenues and
expenses which would have been credited to or incurred by Berry had both this
Agreement and the acquisition of the Cogeneration Assets under the Right to
Purchase Contract been concluded and closed on the Effective Date.  The
operating revenues shall specifically include, but not be limited to, revenue
from power and steam sales.  Operating expenses shall exclude any payments made
pursuant to the Cogeneration Lease or the Cogeneration Premises Lease, any
SOCAL charges, legal fees, interest, amortization, unreasonable travel and
entertainment and management fees in excess of Fifty Dollars ($50) per day.  If
the Cogeneration Assets produce a net income after the Effective Date, then
Tannehill shall pay Berry an Operating Adjustment equal to such net income.
If the Cogeneration Assets produce a net loss after the Effective Date, then
Berry shall pay Tannehill an Operating Adjustment equal to the amount of the
net loss.

               b.   In the event Tannehill does not provide Berry with its
calculation of the Operating Adjustment (the "Calculation") prior to the
Closing, Tannehill shall provide Berry with the Calculation within sixty (60)
days after the Closing.  Berry shall have immediate access at reasonable times
to such books, records and invoices as it deems necessary to verify the
Calculation.  If Berry does not object to the Calculation within ten (10) days
after receipt thereof by Berry, it shall be deemed to be final and binding upon
the parties hereto.  If Berry objects to the Calculation within such ten (10)
days by specifying the items to which it objects, then the parties will attempt
to mutually resolve any differences.  If the differences cannot be resolved
within twenty (20) days after Berry's objection to the Calculation, then all
amounts agreed to shall be paid as provided below and the difference shall be
resolved by arbitration under the Commercial Arbitration Rules of the American
Arbitration Association.  The costs of arbitration shall be shared equally by
the parties.  This Section 2.4 is the only Section or part of this Agreement
which is subject to arbitration jurisdiction.


<PAGE> 7
               c.   Within three (3) days after the final determination of
the Operating Adjustment, the party required to make the Operating Adjustment
payment shall pay, via wire if requested, the other party the Operating
Adjustment payment agreed upon.

          2.5  Allocation of Purchase Price.  The parties agree to allocate
the Purchase Price in accordance with the terms of Code Section 1060 and the
Treasury Regulations promulgated thereunder, and to report this transaction for
federal and state tax purposes in accordance with the agreed-upon allocation in
the form of Exhibit 3 attached hereto and made a part hereof.

          2.6  Closing.  Subject to the provisions of Articles VII and VIII,
the closing (the "Closing") shall take place at 10 a.m., Pacific Standard Time,
at the offices of Berry Petroleum Company, 28700 Hovey Hills Road, Taft,
California, on such date prior to December 1, 1996, as to which Berry and
Tannehill shall mutually agree.  By written notice to the other party, either
Berry or Tannehill shall have the right to extend the Closing an additional
forty-five (45) days in the event that either party is not in a position to
close by December 1, 1996.

          2.7  Proration of Credits and Payment Obligations.  All credits and
payment obligations associated with the Cogeneration Assets, excluding the
leases described in Sections 1.7 and 1.8, including but not limited to lease
rentals and other forms of contractual payments, shall be prorated between
Tannehill and Berry as of the Effective Date.  Tannehill shall be responsible
and shall pay for all such items due, incurred or attributable to the period
prior to the Effective Date and Berry shall be responsible and shall pay for
all such items due, incurred or attributable to the period after such date.

          2.8  Real Estate and Other Taxes.  All real estate, occupation, ad
valorem, personal property and severance taxes and charges on the Cogeneration
Assets shall be prorated as of the Effective Date.  Tannehill shall pay all
such items for all periods prior to such date, however, Berry shall be entitled
to all refunds and rebates with regard to such periods.  In the event Berry
pays additional taxes or charges which are assessed upon or levied against the
Cogeneration Assets after Closing with respect to any period prior to the
Effective Date, Tannehill shall promptly reimburse Berry the amount thereof
upon presentation of a receipt therefor.  If Tannehill elects to challenge the
validity of such bill or any portion thereof, Berry shall extend reasonable
cooperation to Tannehill in such efforts, at no expense to Berry.

          2.9  Documentation of Sale and Transfer of Ownership.  Except as
otherwise provided herein, the Cogeneration Assets shall be conveyed pursuant to
the Instruments of Transfer in such form or forms customary and necessary to
properly transfer the tangible and intangible assets included in the
Cogeneration Assets according to the requirements of any applicable federal,
state or local agency.

               a.   Tannehill shall deliver control of the Cogeneration
Assets to Berry at the Closing subject to the reservations, limitations,
conditions and restrictions contained in this Agreement and the Instruments of
Transfer.


<PAGE> 8
               b.   Tannehill shall make available at Tannehill's offices or

abstracts as may then be available in Tannehill's files.

for the consummation by Tannehill of the transactions contemplated by this

periods being referred to as the "Requisite Regulatory Approvals").

               b.   Tannehill shall use its best efforts to obtain all
consents, approvals, clearances, waivers, orders or authorizations of any
Person necessary to be obtained by Tannehill for Berry to have full use and

Agreement.

          5.3  Litigation and Claims.  Tannehill shall promptly inform Berry

or of Tannehill that is or with the exercise of reasonable business judgment
would be expected to have an adverse effect on the Cogeneration Assets.

this Agreement to be performed or complied with by Tannehill.

the prior written consent of Berry:

as a result of a force majeure, fail to use its best efforts to operate the
Cogeneration Assets in the same manner as they have been historically operated
and Tannehill shall avoid experiencing a loss in electrical generation output
below 14.2 megawatts per day, except for reductions due to scheduled
maintenance. 

               b.   Other than in the ordinary course of business, sell,
lease or otherwise dispose of any Cogeneration Assets or any interests therein,
or enter into, or consent to the entering into of, any agreement granting to
any third Person a right to purchase, lease or otherwise acquire any
Cogeneration Assets or interests therein, except as otherwise provided for in
this Agreement;
               c.   Enter into any agreement or incur any obligation, the
terms of which would be violated by the consummation of the transactions

<PAGE> 20
               d.   (i) Enter into any new line of business with respect to
the Cogeneration Assets; (ii) change its investment, liability management and
other material policies in any respect; (iii) incur or commit to any capital
expenditures or financing relative to the Cogeneration Assets; (iv) otherwise
acquire or agree to acquire any assets for a total consideration in the
aggregate in excess of Five Thousand Dollars ($5,000); or (v) waive any right
under or cancel any contract, debt or claim listed in any exhibits hereto or
the Tannehill Disclosure Letter, which waiver or cancellation would have an
adverse effect on the Cogeneration Assets;

               e.   Maintain books of account relative to the Cogeneration
Assets other than in the usual, regular and ordinary manner in accordance with
good business practices or make any change in any of its accounting methods or
practices; or

               f.   Take any action that would or might reasonably be
expected to result in any of the conditions to Closing set forth in Article VII
hereof not being satisfied.

          5.6  Maintain Cogeneration Assets and Operations.  Except for
entering into the Right to Purchase Contract for acquisition of the
Cogeneration Assets as provided in Sections 1.26 and 5.10 hereof, during the
period from the date hereof through the Closing, Tannehill shall (a) carry on
its business in the usual, regular and ordinary course in a good and diligent
manner consistent with sound business practices and in compliance with all
applicable laws, rules and regulations; (b) not introduce any new method of
management or operation; (c) use its best efforts to preserve its business
organization, maintain its rights and franchises, keep available the services
of its officers and employees and preserve the goodwill and its relationships
with customers, suppliers and others having business dealings with it;
(d) preserve in full force and effect all leases, operating agreements,
easements, rights of way, permits, licenses, contracts and other agreements
which relate to the Cogeneration Assets (other than those expiring by their
terms); (e) use its best efforts to perform or cause to be performed all of its
obligations in or under any of such leases, agreements and contracts to be
transferred as part of the Cogeneration Assets; (f) use its best efforts to
safeguard and maintain secure all reports and other confidential data in the
possession of Tannehill relating to the Cogeneration Assets; and (g) use its
best efforts to operate its business and activities in the same manner as they
have been carried out and to maintain the same level of expenditure as have
previously been incurred in connection with such business and activities.

          5.7  Exclusive Dealing.  Tannehill shall not directly or indirectly,
through any representative or otherwise, solicit or entertain offers from,
negotiate with or in any manner encourage, discuss, accept or consider any
proposal of any Person relating to the acquisition of the assets or business,
in whole or in part of Tannehill, whether through direct purchase,
consolidation or other business combination (other than sales of inventory or
in the ordinary course of business) so long as this Agreement has not been
terminated.  Tannehill recognizes that Berry has and continues to incur
substantial time and expense in evaluating this transaction.  Tannehill
acknowledges that Berry, in reliance on this Section 5.7, will continue to
incur additional time, effort and expense.  Tannehill has agreed to this
provision due to the unique terms specified in the AIP and contemplated in
this transaction.



<PAGE> 21
          5.8  Termination Fee.  In the event that Tannehill breaches Section
5.7 hereof and within twelve (12) months after such breach or termination,
Tannehill closes a transaction with an unrelated third party relating to the
acquisition of a Material portion of the Cogeneration Assets or the business of
Tannehill, in whole or part, whether through direct purchase, merger,
consolidation or other business combination (other than sales of inventory or
immaterial portions of Tannehill's Cogeneration Assets in the ordinary course),
then, immediately upon such closing, Tannehill shall pay to Berry the sum of
Twenty Thousand Dollars ($20,000).  Such payment shall constitute liquidated
damages and, in the absence of fraud or bad faith, shall be in lieu of any
other penalty or remedy Berry might otherwise seek, the parties having
determined that the 



<PAGE> 22
actual damages resulting from the events for which such liquidated damages are
to be awarded would be extremely difficult and uncertain to calculate and that
liquidated damages above represent a good faith estimate of such actual
damages.

the extent available through the best efforts of Tannehill, originals or copies
of all insurance policies issued to Monarch, Solar or Tannehill covering or
relating to the Cogeneration Assets from the date of its construction to the
Closing; and (g) executed Right to Purchase Contract.

          5.11 Taxes.  Tannehill shall pay any documentary transfer, sales or
use taxes that may become due on the purchase and sale of the Cogeneration

                            ARTICLE X
                         INDEMNIFICATION

          10.1 Indemnification by Berry.  Berry agrees to indemnify, defend
and hold Tannehill, and agents of Tannehill, harmless from and against any and
all loss, liability, damage, costs and expenses (including interest, penalties,
settlements, fines, costs and expenses incurred in connection with
investigating and defending any claims or causes of action, and reasonable
attorneys' fees) that Tannehill and its agents may incur or become subject to
arising out of or due to any inaccuracy of any representation or the breach of
any warranty, covenant, undertaking or other agreement of Berry contained in
this Agreement.

          10.2 Indemnification by Tannehill and the Shareholders.  Tannehill
and the Shareholders, jointly and severally, agree to indemnify, defend and
hold Berry, and the officers, directors, employees and agents of Berry
(collectively, the officers, directors, employees and agents being referred to
in each case as its "Related Parties") harmless from and against any and all
lawsuits, liability, damages, costs and expenses (including interest,
penalties, settlements, fines, costs and expenses incurred in connection with
investigating and defending any claims or causes of action, and reasonable
attorneys' fees) that Berry and its Related Parties may incur or become subject
to or arising out of or due to (a) any inaccuracy of any representation or the
breach of any warranty, covenant, undertaking or other agreement of Tannehill
or the Shareholders contained in this Agreement, or (b) any claim by SOCAL,
PG&E, Solar, or any other creditor of Tannehill or the Shareholders against
Berry based upon or related to, in whole or in part, the SOCAL Contract, the
SOCAL Litigation or the transfer of the Cogeneration Assets to Berry.

          10.3 Survival.  The several warranties, indemnities,
representations, covenants and agreements of the parties contained in this
Agreement and in any other instrument delivered pursuant hereto shall survive
the Closing and shall remain in full force and effect thereafter.

          10.4 Notice and Opportunity to Defend.

               a.   If a party seeking indemnification (the "Indemnitee")
becomes aware of any matters that it believes may give rise to an indemnifiable
claim, or asserts any claim that it believes may be indemnifiable pursuant to
this Agreement, the Indemnitee shall give the party obligated to provide
indemnification (the "Indemnifying Party") prompt written notice of such matter
or claim, stating with particularity the nature of such matter or the
aforementioned claim and the amount thereof.  Failure to provide such notice
shall not affect the right of the Indemnitee to indemnification except to the
extent such failure shall have resulted in


<PAGE> 28
liability to the Indemnifying Party that could have been actually avoided had
such notice been provided within such required time period.

               b.   If the matter that the Indemnitee believes gives rise to
an indemnifiable claim does not involve a third party claim against an
Indemnitee, the Indemnifying Party shall have thirty (30) days from the date on
which it received notice of such claim pursuant to this Section to respond to
such notice.  If such Indemnifying Party accepts responsibility or does not
respond within such thirty (30)-day period, the Indemnifying Party shall
promptly pay to the Indemnitee the full amount of such claim.  If the
Indemnifying Party rejects any liability with respect to such claim, it shall
give written notice of such objection to the Indemnitee within such thirty
(30)-day period and the parties shall seek to resolve such claim by agreement.
If the parties are unable to resolve such claim by agreement within sixty (60)
days following the expiration of such thirty (30)-day period mentioned above,
the parties shall be entitled to pursue, without prejudice to any of their
rights hereunder, such remedies as may be available to the parties under
applicable law.

               c.   In the event any action, suit, proceeding or
investigation is brought against the Indemnitee by a third party which the
Indemnitee believes may give rise to an indemnifiable claim, the Indemnitee
shall give the Indemnifying Party prompt written notice of the commencement of
such action, suit, proceeding or investigation as provided in paragraph a. of
this Section.  Such Indemnifying Party shall have a period of thirty (30) days
after receipt of such notice within which to respond to such notice.  If such
Indemnifying Party does not respond within such thirty (30)-day period or
rejects responsibility for such matter in whole or in part, the Indemnitee
shall be free to pursue, without prejudice to any of its rights hereunder, such
remedies as may be available to such party under applicable law.  If such
Indemnifying Party accepts responsibility, such Indemnifying Party shall, as
between the Indemnitee and the Indemnifying Party, be obligated to compromise
or defend such matter, at its own expense.  The Indemnitee shall employ counsel
of its choice and the Indemnifying Party shall reimburse the Indemnitee for
attorneys' fees and costs.  The Indemnifying Party shall cooperate fully with
the Indemnitee and its counsel in the defense against any such asserted
liability.  Any compromise of such asserted liability by the Indemnitee shall
require the prior written consent of the Indemnifying Party, which shall not be
unreasonably withheld.  If, however, the Indemnitee refuses its consent to a
bona fide offer of settlement that involves solely the payment of cash that the
Indemnifying Party wishes to accept, the Indemnitee may continue to pursue such
matter, free of any participation by the Indemnifying Party, at the sole
expense of the Indemnitee.  In such event, the obligation of the Indemnifying
Party to the Indemnitee shall be equal to the lesser of (i) the amount of the
offer of settlement that the Indemnitee refused to accept plus the costs and
expenses of the Indemnitee prior to the date the Indemnifying Party notified
the Indemnitee of the offer of settlement; and (ii) the actual out-of-pocket
amount the Indemnitee is obligated to pay as a result of such party's
continuing to pursue such matter.  An Indemnifying Party shall be entitled to
recover from the Indemnitee any additional expenses incurred by such
Indemnifying Party as a result of the decision of the Indemnitee to pursue
such matter.



<PAGE> 29
          10.5 General.  The indemnification provided in this Agreement shall
apply regardless of whether the matter subject to indemnification involved an
action taken or omitted that was negligent, grossly negligent or reckless by
the Person to be so indemnified.  It is understood that such indemnification is
intended to be a means of compensating the parties for any damage or liability
directly or indirectly realized by them for matters subject to such
indemnification.  To the extent the indemnification provided for herein may not
be provided to any Person under law, such indemnification shall be required to
be provided to any other Person for whom such indemnification may be
permissible as herein provided.


                            ARTICLE XI
                          MISCELLANEOUS

          11.1 Entire Agreement.  This Agreement and related documents
executed concurrently herewith constitute the sole understanding of the parties
hereto with respect to the matters provided for herein and supersedes the AIP
and any previous agreements and understandings between the parties with respect

terms or provisions of this Agreement shall be binding unless the same shall be
in writing and duly executed by Berry and Tannehill.

          11.2 Successors and Assigns.  This Agreement will inure to the
benefit of and be binding upon Berry, Tannehill and the Shareholders and their

          11.4 Taking of Necessary Action.  Subject to the terms and
conditions of this Agreement, each of the parties hereto agrees, subject to
applicable laws, to use all reasonable best efforts promptly to take or cause
to be taken all action and to promptly do or cause to be done all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.
Without limiting the foregoing and subject to the terms and conditions of this
Agreement, the parties shall use their reasonable best efforts to obtain and
make all consents, approvals, assurances and filings of or with third parties
and Governmental Entities necessary or advisable for the consummation of the
transactions contemplated by this Agreement.  Each party shall cooperate with
the other in good faith to help the other satisfy its obligations hereunder.

          11.5 Invalidity.  Except for satisfaction of the conditions of
Article VII or VIII, and the provisions of Article X, if any term or other
provision of this Agreement is invalid, illegal or incapable of being enforced
by any rule of law, or public policy, all other conditions


<PAGE> 30
and provisions of this Agreement shall nevertheless remain in full force and
effect so long as the economic and legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party.  Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the

("Tannehill"), Berry Petroleum Company, a Delaware corporation ("Berry"), and
Security Pacific Leasing Corporation, a Delaware corporation ("SPLC"), with
reference to the following facts:

                            RECITALS

     A.   Tannehill and SPLC, and certain other entities and individuals, are
parties to a Participation Agreement dated as of August 15, 1994 (the
"Participation Agreement") relating to SPLC's purchase of  the Plant, the lease
of the Premises from the Premises Lessors to SPLC, the sublease  of the
Premises to Tannehill, and the lease of the  Facility to Tannehill.

     B.   Concurrent with the execution and delivery of the Participation
Agreement, and in accordance therewith, the parties thereto entered into the
following agreements, among others:

          1.   The Premises Lease, which provides, inter alia, for the lease
of the Premises by the Premises Lessors to SPLC;

          2.   The Lease dated as of August 15, 1994, among SPLC and
Tannehill, which provides, inter alia, for the lease of the Plant by SPLC to
Tannehill and the sublease of the Premises by SPLC to Tannehill (capitalized
terms herein not otherwise defined herein being used as defined therein);

     C.   The Lease provides, inter alia, that Tannehill has the option to
purchase the Facility  which option cannot be exercised before December 31,
2000;

     D.   SPLC is willing to grant to Tannehill the immediate right to purchase
the Facility, and to consent to Tannehill's assigning such right to Berry, and
to the simultaneous termination of the Lease, all on the terms and conditions
set forth herein; and

     E.   Tannehill and Berry have entered into a Purchase and Sale Agreement
dated as of November 8, 1996 ("Purchase and Sale Agreement"), which provides,
inter alia, for Berry to acquire the Facility from SPLC.

                           AGREEMENT

     NOW, THEREFORE, in consideration of the mutual covenants and agreements as
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

     1.   GRANT OF RIGHT TO PURCHASE

          1.1  Grant of Right to Purchase Facility.  Subject to and upon the
terms and conditions set forth in this Agreement, and in reliance on the

<PAGE> 2
the right to purchase ("Right to Purchase"), effective for all purposes as of

the other property described in Paragraph 1 of the Bill of Sale and Assignment
referred to in Section 3.2, and to the extent assignable by SPLC all rights,
privileges, benefits and powers conferred upon or owned by SPLC under the
documents described in Exhibit "A" to the Quitclaim referred to in Section 3.2
for $6,282,586.47 ("the "Purchase Price"). The parties hereto acknowledge and
agree that the Purchase Price represents full and fair consideration for the
Facility, and that no party hereto will seek any adjustment of the Purchase
Price for any reason whatsoever.  Such Right to Purchase shall terminate on
November 30, 1996, if not exercised before such date.  The Right to Purchase
may be exercised upon 24 hours prior written notice (the "Closing Notice") by

Business Day) on which the documents are to be recorded and the funds are to
be delivered from escrow (the "Closing Date").  

          1.2  Purchase Price.  The Purchase Price shall be due on the Closing
Date. Tannehill shall pay any sales, use or transfer tax  in connection with
the Right to Purchase and the exercise of the Right to Purchase whether such
taxes are assessed on the Closing Date or thereafter.

agrees to pay the Purchase Price directly to SPLC; provided, however, that (a)

the Facility from SPLC to Berry shall not be assumed by Berry, and Tannehill
shall remain obligated to pay such taxes on the Closing Date and/or thereafter,
and (b) Berry does not assume any of Tannehill's obligations under the
Participation Agreement, or otherwise, unless expressly assumed herein or by
separate written agreement.

          2.3  Purchase Price to be Paid by Berry.  Berry agrees that, in
accordance with its acceptance herein of the assignment of Right to Purchase
from Tannehill, it will, subject to satisfaction of the conditions in Section
4, purchase the Facility and will pay the Purchase Price directly to SPLC on
the Closing Date.

release any security interests it may have arising out of or relating to its
ownership of the Facility.

          2.5  Consent by SPLC.  SPLC hereby consents to Tannehill's
assignment to

16.  Foreign Investment in Real Property Tax Act
          The Foreign Investment in Real Property Tax Act of 1980 as amended

     reporting and withholding on the parties to a real estate transaction
     where the transferor(seller) is a non resident alien or non domestic
     corporation or partnership or is a domestic corporation or partnership
     controlled by non residents or non resident corporations or partnerships.

     aware he must return the form completed and signed prior to the close of
     escrow.  If escrow holder does not receive this report prior to close of
     escrow, buyer authorizes escrow holder to charge his account the sum
     of$20.00 which is the fee the County Recorder charges for recording the
     Deed without the completed form.  Buyer is hereby put on notice that the

     day before the close of escrow.

     all funds in escrow in a NON INTEREST bearing fiduciary account at one of
     the following banks:  Union Bank.

20.  Disclosure of Taxpayer Identification Numbers
          Internal Revenue Code Section 6109(h) imposes requirements for
     furnishing, disclosing, and including taxpayer identification numbers in
     tax returns on the parties to a residential real estate transaction
     involving seller provided financing.  The parties understand that the
     disclosure reporting requirements are exclusive obligations between the
     parties to this transaction and that First American Title Insurance
     Company is not obligated to transmit the taxpayer identification numbers
     to the Internal Revenue Service or to the parties.  First American Title
     Insurance Company is not rendering an opinion concerning the effect of
     this law on this transaction,and the parties are not acting on any
     statements made or omitted by the escrow or closing officer.

     Re:  Berry Petroleum Company / Tannehill Electric Company, Inc.
          Asset Purchase and Sale Transaction

Gentlemen:

     We have acted as counsel to Tannehill Electric Company, Inc., a California
corporation ("Tannehill"), in connection with the purchase of substantially all
the assets of Tannehill by Berry Petroleum Company, a Delaware corporation
("Berry"), pursuant to that certain Purchase and Sale Agreement, dated November
8, 1996, by and between Tannehill and Berry (the "Agreement").  Capitalized
terms used in this letter without definition have the meanings given such terms
in the Agreement.

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Berry.

     Based on the foregoing, and in reliance thereon, but subject to the
qualifications herein set forth, we are of the opinion that:

     1.   Tannehill is a corporation duly organized and validly existing under,
and by virtue of, the laws of the State of California and is in good standing
under such laws.  Tannehill has requisite corporate power to own and operate
its properties and assets, and to carry on its business as presently conducted.

     2.   Tannehill has full corporate power and authority to execute and
deliver the Agreement and to perform its obligations under the terms of the
Agreement.

     3.   All corporate action on the part of Tannehill and its directors and
shareholders necessary for the authorization, execution, delivery and
performance of the Agreement and the consummation of the transactions
contemplated thereby, has been taken.  The Agreement has


<PAGE> 2
been duly executed and delivered by Tannehill and constitutes a legal, valid
and binding obligation of Tannehill, enforceable against it in accordance with
its respective terms, except as such enforceability may be limited by or
subject to (a) any bankruptcy, insolvency, reorganization, moratorium or
similar laws relating to creditor's rights generally and (b) general principles
of equity (regardless of whether such enforceability is considered in a
proceeding in equity or at law). 

     4.   The individuals and entities executing the Agreement as shareholders
of Tannehill are the beneficial owners of all the issued and outstanding shares
of Tannehill common stock (the "Shares").  There are no outstanding options,
warrants, rights of first refusal, or other rights calling for the issuance of,
or any security convertible into or exchangeable for, the Shares and no other
person or entity has any right in or to the Shares.

     5.   No consent, approval or authorization of or designation of Tannehill
is required in connection with the valid execution and delivery of the
Agreement, or the consummation of the transactions contemplated thereby on the
Closing thereof, except as such have been obtained or made prior to or upon the
date hereof.

     6.   To our best knowledge, no default exists and no event has occurred
which would constitute a default under, or violation in the due performance and
observance of any term, covenant or condition, or breach of, Tannehill's
Articles of Incorporation or Bylaws or any indenture, license, lease,
franchise, mortgage, instrument, or other agreement to which Tannehill is a
party, or by which it or its properties may be bound; or (a) an event that
would permit any party to any agreement or instrument to terminate it or to
accelerate the maturity of any indebtedness or other obligation of Tannehill;
(b) an event that would result in the creation or imposition of any lien,
charge, or encumbrance on any asset of Tannehill; or (c) an event that would
conflict with any order, rule, or regulation directed to Tannehill by any court
or governmental agency or body having jurisdiction over it.

     7.   Except as disclosed in the Tannehill Disclosure Letter (as defined
in the Agreement), to our best knowledge, there is no suit, action,
arbitration, or legal, administrative, or other proceeding or governmental
investigation pending or threatened against or affecting Tannehill or any of
its businesses or properties or financial or other condition.

     8.   Except as disclosed in the Tannehill Disclosure Letter, there are no
agreements, written or oral, between Tannehill and any other party that affect,
directly or indirectly, the Cogeneration Assets.

     We are members of the bar of the State of California, and accordingly we
do not purport to be experts on, or to be qualified to express any opinion
herein concerning, nor do we express any opinions herein concerning, any law
other than Federal law and the laws of the State of California.

     This opinion letter is limited to the matters expressly stated herein and
no opinion or other statement may be inferred or implied beyond the matters
expressly stated herein.  This


<PAGE> 3
opinion letter is addressed to Berry for the benefit of Berry and is only for
Berry's use in connection with the Agreement.  This opinion letter may not be
relied upon by any other person or entity without prior written consent.  This
opinion is as of this date, and we expressly decline any undertaking to advise
you of any matters arising subsequent to the date hereof which would cause us
to amend any portion of the foregoing in whole or in part.

                                        Very truly yours,

     Re:  Berry Petroleum Company / Tannehill Electric Company, Inc.
          Asset Purchase and Sale Transaction

Gentlemen:

     We have acted as counsel to Tannehill Electric Company, Inc., a California

limited liability company ("Sunset LLC"), in connection with the purchase of
substantially all the assets of Tannehill by Berry Petroleum Company, a Delaware

In connection with the Agreement, Sunset LLC, has entered into an agreement to
indemnify Berry (and other parties) against certain claims and losses (the
"Indemnity").

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Berry.

     Based on the foregoing, and in reliance thereon, but subject to the
qualifications herein set forth, we are of the opinion that:

     1.   Tannehill is a corporation duly organized and validly existing under,
and by virtue of, the laws of the State of California and is in good standing
under such laws.  Tannehill has requisite corporate power to own and operate
its properties and assets, and to carry on its business as presently conducted.

     2.   Sunset LLC is a limited liability company duly organized and validly

conducted.

     3.   Tannehill has full corporate power and authority to execute and
deliver the Agreement and to perform its obligations under the terms of the
Agreement.

     4.   Sunset LLC has full corporate power and authority to execute and
deliver the Indemnity and to perform its obligations under the terms of the
Indemnity.

     5.   All corporate action on the part of Tannehill and its directors and
shareholders necessary for the authorization, execution, delivery and
performance of the Agreement and the consummation of the transactions
contemplated thereby, has been taken.  The Agreement has been duly executed and
delivered by Tannehill and constitutes a legal, valid and binding obligation of
Tannehill, enforceable against it in accordance with its respective terms,
except as such enforceability may be limited by or subject to (a) any
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
creditor's rights generally and (b) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     6.   All action on the part of Sunset LLC and its members necessary for
the authorization, execution, delivery and performance of the Indemnity and the
consummation of the transactions contemplated thereby, has been taken.  The
Indemnity has been duly executed and delivered by Sunset LLC and constitutes a
legal, valid and binding obligation of Sunset LLC enforceable against it in
accordance with its respective terms, except as such enforceability may be
limited by or subject to (a) any bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to creditor's rights generally and (b)
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

     7.   The individuals and entities executing the Agreement as shareholders
of Tannehill are the beneficial owners of all the issued and outstanding shares
of Tannehill common stock (the "Shares").  There are no outstanding options,
warrants, rights of first refusal, or other rights calling for the issuance of,
or any security convertible into or exchangeable for, the Shares and no other
person or entity has any right in or to the Shares.

     8.   The individuals and entities executing the Indemnity as members of
Sunset LLC are the beneficial owners of all the ownership interests in
Sunset LLC (the "Interests").  There are no outstanding options, warrants,
rights of first refusal, or other rights calling for the issuance of, or any
security convertible into or exchangeable for, the Interests and no other
person or entity has any right in or to the Interests.



<PAGE> 3
     9.   No consent, approval or authorization of or designation of Tannehill
is required in connection with the valid execution and delivery of the
Agreement, or the consummation of the transactions contemplated thereby on the
Closing thereof, except as such have been obtained or made prior to or upon the
date hereof.

     10.  No consent, approval or authorization of or designation of Sunset LLC
is required in connection with the valid execution and delivery of the
Agreement, or the consummation of the transactions contemplated thereby on the
Closing thereof, except as such have been obtained or made prior to or upon the
date hereof.

     11.  To our best knowledge, no default exists and no event has occurred
which would constitute a default under, or violation in the due performance and
observance of any term, covenant or condition, or breach of, Tannehill's
Articles of Incorporation or Bylaws, Sunset LLC's Article of Organization or
Operating Agreement, or any indenture, license, lease, franchise, mortgage,
instrument, or other agreement to which Tannehill is a party, or by which it or
its properties may be bound; or (a) an event that would permit any party to any
agreement or instrument to terminate it or to accelerate the maturity of any
indebtedness or other obligation of Tannehill; (b) an event that would result
in the creation or imposition of any lien, charge, or encumbrance on any asset
of Tannehill; or (c) an event that would conflict with any order, rule, or
regulation directed to Tannehill by any court or governmental agency or body
having jurisdiction over it.

     12.  Except as disclosed in the Tannehill Disclosure Letter (as defined
in the Agreement), to our best knowledge, there is no suit, action,
arbitration, or legal, administrative, or other proceeding or governmental
investigation pending or threatened against or affecting Tannehill, Sunset LLC
or any of their businesses or properties or financial or other condition.

     13.  Except as disclosed in the Tannehill Disclosure Letter, there are no
agreements, written or oral, between Tannehill, Sunset LLC and any other party
that affect, directly or indirectly, the Cogeneration Assets.

     14.  The transfer of the Cogeneration Assets to Berry will not violate the
terms of any agreement, document, or court order entered into or issued in
connection with the SOCAL Litigation.

                            ARTICLE II
                            INDEMNITY 

     2.1  Indemnification by Sunset.  Sunset LLC and the Members, jointly and
severally, hereby agree to indemnify, defend (with counsel reasonably acceptable
to Berry) and hold Berry, and the officers, directors, employees and agents of
Berry (collectively, the officers, directors, employees and agents being
referred to in each case as its "Related Parties") harmless from and against
any and all lawsuits, liability, damages, costs and expenses (including
interest, penalties, settlements, fines, costs and expenses incurred in
connection with investigating and defending any claims or causes of action, and
reasonable attorneys' fees) that Berry and/or its Related Parties may incur or
become subject to or arising out of or due to (a) any inaccuracy of any
representation or the breach of any warranty, covenant, undertaking or other
agreement contained in this Agreement, or (b) any claim by SOCAL against Berry
based upon or related to, in whole or in part, the SOCAL Contract, the SOCAL
Litigation, the Facility or the transfer of the Cogeneration Assets (as that
term is defined in the TEC Agreement) to Berry.  In no event, shall the
indemnity contained in this Agreement modify the terms of any other indemnify
in favor of Berry from TEC, TOCI, TOC or the TOC Partners in whatever capacity.
All such indemnities shall continue to be in full force and effect and are not
modified or supplemented as a result of this Agreement.  Berry shall have full
discretion to proceed against any and all indemnitors with respect to any
claims, liabilities, costs, judgments or settlements for which indemnity is
expressly provided under the terms of any such other agreement or undertaking.

     2.2  Obligations Absolute.  The obligations of Sunset hereunder shall
remain in full force and effect without regard to, and shall not be affected or
impaired by the following, nor shall any of the following give Sunset any
recourse or right of action against Berry:

          (a)  Any breach or termination by any party of its obligations under
the O&M Agreement;

          (b)  Any express or implied amendment, modification, renewal,
addition, supplement, extension of the Consent or the O&M Agreement;

          (c)  Any exercise or non-exercise or waiver by Berry of any right
or privilege under the O&M Agreement or the Consent and any instruments
delivered in connection therewith;

          (d)  Any bankruptcy, insolvency, reorganization, composition,
adjustment, dissolution, liquidation or other like proceeding relating to
Sunset or Berry, or any entity or individual comprising same, or any action
taken with respect to this Agreement by any trustee or receiver, or by any
court, in any such proceeding, whether or not Sunset shall have had notice or
knowledge of any of the foregoing;



<PAGE> 4
          (e)  Any release or discharge of any other party at any time
directly or contingently liable for obligations evidenced by, or referenced in,
the O&M Agreement or the Consent or in connection therewith;

          (f)  Any assignment or other transfer of this Agreement in whole or
in part;

          (g)  Any acceptance of partial performance by SOCAL (or its
successors or assigns) of the SOCAL Contract or with respect to the SOCAL
Litigation or the existence of any claims, disputes or allegations by or
between SOCAL on the one hand, and TEC or Sunset LLC, or any of them, on the
other hand, arising out of, relating to, or in connection with, the SOCAL
Contract, the SOCAL Litigation, the O&M Agreement or the Facility from and
after the date on which the O&M Agreement is assigned by TEC to Berry as
contemplated under the Consent; and/or

          (h)  Any concurrent and/or contributory negligence (whether active
or passive or of any kind or description) or fault of Berry.

     2.3  Evidence of Satisfactory Condition.  Sunset LLC acknowledges that,
in agreeing to consummate the transactions contemplated under the Consent,
Berry is relying upon Sunset LLC's financial ability to support this Agreement.
In order to provide assurances to Berry of Sunset LLC's continuing ability to
meet its obligations under this Agreement, Sunset LLC shall provide Berry with
financial statements for Sunset LLC upon written request from Berry, given in
the manner required with respect to any notice provided under this Agreement,
in addition to all other financial information required under the Consent or
Security Agreement.

     2.4  Sunset LLC's Affirmative Duty.  Sunset shall have an affirmative duty
to monitor, on a best-efforts basis, the existence of any facts, course of
conduct or actions taken which could lead to or result in any Claims by SOCAL
against Berry which give rise to Sunset LLC's obligations hereunder, and shall
forthwith give Berry notice of such Claims.  Sunset shall have a further duty to
perform each and every obligation set forth in this Agreement with regard to
any Claim of SOCAL of which it knew or should have known, even in the absence
of written notice by Berry.  It is the express intention of the parties that
Berry shall have no duty and bear no burden with respect to any Claim by or on
behalf of SOCAL.

     2.5  Payments and Performance.  Sunset agrees that whenever it shall make
any payment to Berry or otherwise perform any of the obligations under this
Agreement on account of the liability hereunder, it will deliver such payment or
tender such performance to Berry at the address therefor specified hereinbelow,
or at such other address as may be required by Berry, or any entity comprising
Berry, and notify Berry, in writing that such payment is made or performance
tendered under this Agreement for such purpose.  No payment made hereunder by
Sunset LLC to Berry shall constitute Sunset LLC as a creditor of Berry.

     2.6  Presumptions and Effect of Certain Proceedings.  Upon making a
request for indemnification, for a Claim covered hereunder, it shall be
presumed that such indemnification is not prohibited by law and Sunset shall
have the burden of proof to show that such


<PAGE> 5
indemnification is expressly prohibited by applicable law in order to overcome
that presumption in reaching any contrary determination.  If the person or
persons so empowered to make the determination shall have failed to make the
requested indemnification within sixty (60) days after any judgment, order,
settlement, dismissal, arbitration award, conviction, acceptance of a plea of
nolo contendere or its equivalent, or other disposition or partial disposition
of any proceeding or any other event which could enable Sunset to determine
Berry's entitlement to indemnification, the requisite determination of
entitlement to indemnification shall be deemed to have been made and Berry
shall be absolutely entitled to indemnification under this Agreement, absent
(a) misrepresentation or omission by Berry of a material fact in the request
for indemnification or (b) a specific finding (which has become final) that
all or any part of such indemnification is expressly prohibited by law.  The 
termination of any proceeding by judgment, order, settlement, arbitration award
or conviction, or upon a plea of nolo contendere or its equivalent, shall not
of itself (i) adversely affect the rights of Berry to indemnification except as
may be provided herein, (ii) create a presumption that Berry did not act in
good faith and in a manner which it reasonably believed to be in or not opposed
to the best interests of Sunset, or (c) with respect to any criminal action or
proceeding, create a presumption that Berry had reasonable cause to believe
that its conduct was unlawful.

     2.7  Remedies of Berry in Cases of Determination Not to Indemnify or to
          Advance Expenses.

          (a)  Determination.  In the event that (i) an initial determination
is made that Berry is not entitled to indemnification, (ii) advances are not
made pursuant to this Agreement, (iii) payment has not been timely made
following a determination of entitlement to indemnification pursuant to this
Agreement or (iv) Berry otherwise seeks enforcement of this Agreement, Berry
shall be entitled to a final adjudication in an appropriate court of the State
of California of its entitlement to such indemnification or advance.  Sunset
shall not oppose Berry's right to seek any such adjudication.  In any such
proceeding Berry shall be presumed to be entitled to indemnification under this
Agreement and Sunset shall have the burden of proof to overcome that
presumption.  

          (b)  No Prejudice.  In the event an initial determination has been
made, in whole or in part, that Berry is not entitled to indemnification, the
decision in the judicial proceeding provided in paragraph (a) of this Section
2.7 shall be made de novo and Berry shall not be prejudiced by reason of a
determination that it is not entitled to indemnification.

          (c)  Effect of Determination.  If an initial determination is made
or deemed to have been made pursuant to the terms of this Agreement that
indemnification of Berry provided hereunder is not expressly prohibited by law,
Berry shall be entitled to such indemnification and Sunset shall be bound by
such determination in the absence of (i) a misrepresentation or omission of a
material fact by Berry or (ii) a specific finding (which has become final) that
all or any part of such indemnification is expressly prohibited by law.

          (d)  Stipulation.  Sunset shall be precluded from asserting that the
procedures and presumptions of this Agreement are not valid, binding and
enforceable.  Sunset LLC shall


<PAGE> 6
stipulate in any such court that Sunset is bound by all the provisions of this
Agreement and is precluded from making any assertion to the contrary.

          (e)  Expenses.  Expenses incurred by Berry in good faith in
connection with its request for indemnification under, seeking enforcement of,
or to recover damages for breach of, this Agreement shall be borne by Sunset.

     2.8  Grant of Security Interest.  Sunset LLC shall grant a security
interest in the assets of Sunset LLC pursuant to the Reserve Security
Instruments and the Security Agreement which shall serve as security for Sunset
LLC's due and punctual performance of all obligations under the Consent and
this Agreement and shall be a continuing lien on the assets of Sunset LLC for
the term of this Agreement.  Sunset LLC shall promptly execute and deliver all
Reserve Security Instruments as contemplated under the Consent and this
Agreement.

     2.9  Retention of Reserve by Members.  In the event the Reserve, or any
part of it, is distributed to the Members due to dissolution of Sunset LLC, or
otherwise, the Members shall hold, invest, retain and pay out such Reserve
under the terms of the Consent, this Agreement, the Sunset LLC Operating
Agreement and any Reserve Security Instruments.

                           ARTICLE III
                  REPRESENTATIONS AND WARRANTIES

     3.1  Representations and Warranties.  Sunset makes the following
representations and warranties which shall be continuing representations and
warranties:

          (a)  Organization, Standing and Power.  Sunset LLC is validly
existing and in good standing under the laws of the States of the United States
in which it does business and has full power and authority to execute, deliver
and perform its obligations under this Agreement.

          (b)  Binding Effect.  This Agreement has been duly authorized,
executed and delivered by Sunset, and is the valid, legal and binding
obligation of Sunset, enforceable against it in accordance with its terms.

          (c)  No Consents.  To Sunset's knowledge, after due and diligent
investigation, no registration with, consent or approval of, or any other
action by, any federal, state or other governmental agency, authority or
regulatory body, foreign or domestic, is required as a condition to, or
otherwise in connection with, the execution, delivery and performance of this
Agreement by Sunset LLC.  Neither the execution, delivery or performance of
this Agreement has resulted or will result in any breach of any provision of,
or constitute a default (or an event which with or without notice and/or lapse
of time would constitute a default), or result in the creation of any lien,
charge or other encumbrance upon any of the assets of Sunset LLC, under Sunset
LLC's organizational documents, or any agreement or instrument to which Sunset
LLC is a party or by which it is bound or any statute, rule, judgment, order or
regulation of any court or governmental authority applicable to it.



<PAGE> 7
          (d)  Purpose of Organization.  Sunset LLC hereby acknowledges and
warrants that it has been established and is organized, for the primary purpose
of providing to Berry the indemnities and agreements set forth in this
Agreement, and to provide similar indemnities and agreements for the benefit of
other parties in connection with the SoCal Gas Litigation and the SoCal
Liabilities, all as more particularly described in the Consent.  The Members
have determined that it is in the best interests of Sunset LLC to execute,
deliver and perform this Agreement for the benefit of Berry and to enter into
the arrangements and undertakings set forth herein.

          (e)  Insolvency.  The execution and delivery of this Agreement will
not (i) render Sunset LLC insolvent under generally accepted accounting
principles nor render it Insolvent (as defined below), (ii) leave Sunset LLC
with remaining assets which constitute unreasonably small capital given the
nature of its business, or (iii) result in the incurrence of Debts (as defined
below) beyond the ability of Sunset LLC to pay them when and as they mature.
For the purposes of this Section (e), "Debts" includes any legal liability for
indebtedness, whether matured or unmatured, liquidated or unliquidated,
absolute, fixed or contingent.

          (f)  Consent.  Sunset LLC has read and examined, or is otherwise
familiar with, the Consent and is aware and has full knowledge of Sunset LLC's
obligations and duties thereunder.

                            ARTICLE IV
                        GENERAL PROVISIONS

     4.1  Complete Agreement; Interpretation.  This Agreement, together with
the Consent, and all instruments or other documents to be executed and
delivered thereunder, supersede any prior negotiations, discussions or
communications between Sunset LLC and Berry and constitute the entire
agreement of such parties with respect to the subject matter of this Agreement.
Each party to this Agreement has substantial experience with the subject matter
of this Agreement and each has fully participated in the negotiation and
drafting of this Agreement and has been advised by counsel of its choice with
respect to the subject matter hereof.  Accordingly, this Agreement shall be
construed without regard to the rule that ambiguities in a document are to be
construed against the drafter. 

     4.2  Exercise of Remedies; Successors; Etc.  No delay or failure by Berry
to exercise any remedy against Sunset will be construed as a waiver of that
right or remedy.  All remedies of Berry are cumulative.  Any claim for
performance under this Agreement, or exercise of any right or remedy accruing
under this Agreement to the benefit of Berry may be made or exercised by each
entity comprising Berry as if Berry collectively has made such claim or
exercised such right or remedy.  When the context in which the words are used
in this Agreement indicates that such is the intent, words in the singular
number shall include the plural and vice-versa.  If any one or more of the
provisions of this Agreement should be determined to be illegal or
unenforceable, all other provisions shall remain effective.  Sunset shall not
have the right to assign any of its rights or obligations under this Agreement
without the prior written consent of


<PAGE> 8
Berry, or its successors or assigns, which consent may be withheld in such
party's sole discretion. 

     4.3  Demands.  Except as set forth in Section 2.4 above, each demand by
Berry for performance or payment hereunder shall be in writing and shall be
made in the manner set forth in Section 4.10 below.

     4.4  Invalidity.  If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic and legal
substance of the transactions contemplated hereby is not affected in any manner
materially adverse to any party.  Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner to the end that transactions contemplated hereby are fulfilled to the
extent possible. 

     4.5  Attorneys' Fees.  In the event of any claim, dispute or controversy
arising out of or relating to this Agreement, including an action for
declaratory relief, the prevailing party in such action or proceeding shall be
entitled to recover its taxable costs or arbitration fees, and reasonable
out-of-pocket expenses, including, but not limited to, telephone calls,
photocopies, expert witnesses, travel, computer expenses related to litigation,
and attorneys' fees to be fixed by the court or the arbitrator.  Such recovery
shall include court costs, out-of-pocket expenses and attorneys' fees on
appeal, if any.  The court shall determine who is the "prevailing party,"
whether or not the dispute or controversy proceeds to final judgment.

     4.6  Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original
and all of which shall constitute the same instrument.

     4.7  Headings.  The headings of the articles, sections and paragraphs of
this Agreement and of the exhibits hereto are included for convenience only and
shall not be deemed to constitute part of this Agreement or to affect the
construction hereof or thereof.

     4.8  Construction and References.  Words used in this Agreement,
regardless of the number or gender specifically used, shall be deemed and
construed to include any other number, singular or plural, and any other
gender, masculine, feminine or neuter, as the context shall require.  Unless
otherwise specified, all references in this Agreement to articles, sections,
paragraphs or clauses are deemed references to the corresponding articles,
 sections, paragraphs or clauses in this Agreement.

     4.9  Modification and Waiver.  Any of the terms or conditions of this
Agreement may be waived in writing at any time by the party which is entitled
to the benefits thereof.  No waiver of any of the provisions of this Agreement
shall be deemed to or shall constitute a waiver of any other provisions hereof
(whether or not similar).

     Re:  Berry Petroleum Company / Tannehill Electric Company, Inc.
          Asset Purchase and Sale Transaction

Gentlemen:

     We have acted as counsel to Berry Petroleum Company, a Delaware
corporation ("Berry"), in connection with the purchase of substantially all the
assets of Tannehill Electric Company, Inc., a California corporation
("Tannehill"), by Berry, pursuant to that certain Purchase and Sale Agreement,
dated November 8, 1996, by and between Tannehill and Berry (the "Agreement").

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Tannehill.

     1.   Berry is a corporation duly organized and validly existing under, and
by virtue of, the laws of the State of Delaware and is in good standing under
such laws.  Berry has requisite corporate power to own and operate its
properties and assets, and to carry on its business as presently conducted.

     2.   Berry has full corporate power and authority to execute and deliver
the Agreement and to perform its obligations under the terms of the Agreement.

     3.   All corporate action on the part of Berry necessary for the
authorization, execution, delivery and performance of the Agreement and the
consummation of the transactions contemplated thereby, has been taken.  The
Agreement has been duly executed and delivered by Berry and constitutes a
legal, valid and binding obligation of Berry, enforceable against it in
accordance with its respective terms, except as such enforceability may be
limited by or subject to (a) any bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to


<PAGE> 2
creditor's rights generally and (b) general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     4.   No consent, approval or authorization of or designation of Berry is
required in connection with the valid execution and delivery of the Agreement
by Berry, or the consummation by Berry of the transactions contemplated thereby
on the Closing thereof, except as such have been obtained or made prior to or
upon the date hereof.

     5.   To our best knowledge, there is no suit, action, arbitration, or
legal, administrative, or other proceeding or governmental investigation that
is material to the transactions contemplated by the Agreement pending or
threatened against or affecting Berry or any of its businesses or properties or
financial or other condition.

     We are members of the bar of the State of California, and except for our
opinion set forth in Paragraph 1 above, we do not purport to be experts on, or
to be qualified to express any opinion herein concerning, nor do we express any
opinions herein concerning, any law other than Federal law and the laws of the
State of California.

     This opinion letter is limited to the matters expressly stated herein and
no opinion or other statement may be inferred or implied beyond the matters
expressly stated herein.  This opinion letter is addressed to Tannehill for the
benefit of Tannehill and is only for Tannehill's use in connection with the
Agreement.  This opinion letter may not be relied upon by any other person or
entity without prior written consent.  This opinion is as of this date, and we
expressly decline any undertaking to advise you of any matters arising
subsequent to the date hereof which would cause us to amend any portion of the
foregoing in whole or in part.

                              Very truly yours,

                              NORDMAN, CORMANY, HAIR & COMPTON

and six (6) notes aggregating Three Million, Two Hundred Thousand Dollars
($3,200,000) (collectively, "Note 2") in substantially the same form as in

Adjustment").  The Operating Adjustment shall not be handled through Escrow.
Allocation of the Purchase Price among Tannehill Oil and the Partners shall be
the responsibility of Tannehill Oil and the Partners after payment of the

            2.4  Operating Adjustment.
  
                 a.   October 1, 1996, at 12:01 a.m. shall be considered the
"Effective Date" of this Agreement, and the oil and gas operations included in
the Assets shall be deemed to be for the account of Berry from and after that
date.  The Operating Adjustment will occur


<PAGE> 6
after the Closing in an amount equal to the difference between (i) the value of
oil and gas produced by Tannehill Oil after the Effective Date and (ii) the
normal cost of producing oil and gas after the Effective Date, as determined by
Tannehill's customary accounting method adjusted to reflect only necessary
operating revenues and expenses which would have been credited to or incurred
by Berry had this transaction closed on the Effective Date.  The oil tanks
shall be gauged at 12:01 a.m. on the Effective Date.  The value of oil and gas
produced by Tannehill after the Effective Date shall be the net sales after
royalties adjusted for the change in inventory between the Effective Date and
the Closing.  If the value of the oil and gas produced after the Effective Date
is greater than said cost, then Tannehill shall pay Berry an Operating
Adjustment equal to the amount of the difference.  If the value of the oil and
gas produced after the Effective Date is less than said cost, then Berry shall
pay Tannehill an Operating Adjustment equal to the amount of the difference.
 
                 b.   In the event Tannehill does not provide Berry with its
calculation of the Operating Adjustment (the "Calculation") prior to the
Closing, Tannehill shall provide Berry with the Calculation within sixty (60)
days after the Closing.  Berry shall have immediate access at reasonable times
to such books, records and invoices as it deems necessary to verify the
Calculation.  If Berry does not object to the Calculation within ten (10) days
after receipt thereof by Berry, it shall be deemed to be final and binding upon
the parties hereto.  If Berry objects to the Calculation within such ten (10)
days by specifying the items to which it objects, then the parties will attempt
to mutually resolve any differences.  If the differences cannot be resolved
within twenty (20) days after Berry's objection to the Calculation, then all
amounts agreed to shall be paid as provided below and the difference shall be
resolved by arbitration under the Commercial Arbitration Rules of the American
Arbitration Association.  The costs of arbitration shall be shared equally by
the parties.  This Section 2.4 is the only Section or part of this Agreement
which is subject to arbitration jurisdiction.

                 c.   Within three (3) days of the final determination of the
Calculation, the party required to make the Operating Adjustment payment
shall pay, via wire if requested,  the Operating Adjustment payment agreed upon
to the other party.

                 d.   For managing Tannehill Oil subsequent to September 30,
1996, Tannehill shall only be entitled to be credited for management fees at
the rate of One Hundred Fifty Dollars ($150) per day and shall not be entitled
to reimbursement of overhead costs including, but not limited to, legal
expenses, accounting costs, loan fees and interest, contributions, dues and
assessments, 401K retirement costs, severance payments, payments of accrued
vacation pay, payments in lieu of compensatory time off or excessive travel or
entertainment costs or expenses.  Distributions to Partners subsequent to
September 30, 1996, shall not be included in the costs.
 
            2.5  Assets to be Conveyed to Berry.  The Assets to be conveyed
to Berry by Tannehill are the following assets owned and/or operated by
Tannehill Oil: (a) all of the fee real property, oil and gas leases (including
all of Tannehill's interest in that certain oil and gas lease known as the

the buildings, structures, tanks and pipelines on or under the property owned
and/or operated by Tannehill Oil, as are described in the Disclosure Letter
from Tannehill delivered to Berry at or prior to execution hereof, which shall
refer to the Sections of this Agreement (the "Tannehill Disclosure Letter");
(c) all equipment and supplies related to or utilized in operating the oil
properties and facilities owned and/or operated by Tannehill as described in
the Tannehill Disclosure Letter, excluding only that portion of the "yellow

Tannehill shall convey the Assets to Berry free and clear of all liens and
Encumbrances (other than Permitted Encumbrances).  Any asset of Tannehill Oil
not described in Exhibit 9 or the Tannehill Disclosure Letter shall be conveyed
to Berry subject to Berry's right, in its sole discretion, to refuse to accept
such asset by written notice to Tannehill Oil within thirty (30) days after
Berry has received written notice from Tannehill Oil that the asset is included
in the Assets.  Subject to paragraph 3.16a hereof, Tannehill Oil employees will
not be employed by Berry.  In addition, the Partners shall convey to Berry all
their right, title and interest as Premises Lessor under that certain
Cogeneration Premises Lease, dated as of August 15, 1994, between the Partners
and Security Pacific Leasing Corporation, a Delaware corporation (the
"Cogeneration Premises Lease"), free and clear of all Encumbrances, excluding

                 b.   Employees of Tannehill Oil shall not assert claims
against Berry based on employment by Tannehill Oil for severance, retirement
benefits, health benefits, deferred compensation, violations of any federal,
state or local laws or statutes, wages or other benefits or compensation. 
Employees of Tannehill Oil not employed by Berry shall not assert any claim
against Berry for discriminatory hiring practices based on state or federal
laws or statutes, union contracts or for benefits based upon the Employee
Retirement Income Security Act of 1974, as Amended ("ERISA").

                 c.   The Tannehill Disclosure Letter sets forth a list of all
plans and other arrangements involving direct or indirect compensation or
benefits to Partners, consultants or providing employee benefits to employees of
Tannehill Oil, including, without limitation, all "employee benefit plans" as
defined in Section 3(3) of ERISA, and all bonus, incentive, deferred
compensation, supplemental retirement, severance and other similar fringe or
employee benefit plans, and all employment or executive compensation agreements
(collectively, the "Benefit Plans").  True and complete copies of the Benefit
Plans have been made available to Berry.  To the extent applicable, the Benefit
Plans comply, in all material respects, with the requirements of ERISA and the
Code, and any Benefit Plan intended to be qualified under Section 401(a) of the
Code has been determined by the IRS to be so qualified.  No Benefit Plan is
covered by Title IV of ERISA or Section 4112 of the Code.  No Benefit Plan has
incurred any liability or penalty under Section 4975 of the Code or Section
502(i) of ERISA.  Each Benefit Plan has been maintained and administered in all
material respects in compliance with its terms and with ERISA and the Code to
the extent applicable thereto.  There are no pending or anticipated claims
against or otherwise involving any of the Benefit Plans and no suit, action or
other litigation (excluding claims for benefits incurred in the ordinary course
of Benefit Plan activities) has been brought against or with respect to any

Material adverse effect.  Neither Tannehill Oil nor any entity under "common
control" within the meaning of ERISA Section 4001 with Tannehill Oil or its
Affiliates has contributed to, or been required to contribute to, any
"multiemployer plan" (as defined in Sections 3(37) and 4001(a)(3) of ERISA).
Except as may be required by law, Tannehill Oil does not maintain or contribute
to any plan or arrangement which provides or has any liability to provide life
insurance, medical or other employee welfare benefits to any employee or former
employee upon his retirement or termination of employment, and Tannehill has
never represented, promised or contracted (whether in oral or written form) to
any employee or former employee that such benefits would be provided.
 
                 d.   Except as disclosed in the Tannehill Disclosure Letter,
Tannehill Oil is not currently nor has it ever been a party to any employee
pension or welfare plan to which ERISA applies or to which Tannehill Oil was
required to make contributions for the benefit of its employees.

                 e.   Neither Tannehill Oil nor any of its Affiliates is a
party to, or bound by, any collective bargaining agreement, contract or other
agreement or understanding


<PAGE> 17
with a labor union or labor union organization.  There is no unfair labor
practice or labor arbitration proceeding pending or threatened against
Tannehill Oil or any of its Affiliates relating to their business which,
if determined adversely to Tannehill Oil or the Affiliate would have a
Material adverse effect.  There are no organizational efforts with respect to
the formation of a collective bargaining unit presently being made or
threatened involving employees of Tannehill Oil or any of its Affiliates.
 
            3.17 Investigation.  Tannehill and its agents, counsel and
accountants have had reasonable access to representatives of Berry to make such
investigations as they desired with respect to the business, operations and
affairs of Berry in connection with the transactions contemplated hereby.  In
determining whether to consummate the transactions contemplated hereby, 
Tannehill is relying solely on the terms, covenants, representations,
warranties and indemnities herein and on their own investigations into and
analysis of the business, operations and condition (financial or otherwise) of
Berry and have not relied on Berry, or its officers or directors, with respect
to the interpretation of data relating to the valuation of Tannehill, the
income tax ramifications of this purchase and sale, and/or the ability of Berry
to operate the Assets.

duly authorized by all necessary corporate action on the part of Berry.  This
Agreement has been duly and validly executed and delivered by Berry and

against it in accordance with its terms, except to the extent that such
enforceability (a) may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to creditors' rights generally; and
(b) is subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).  The

with, or result in any breach of, or default or loss of any right under (or
an event or circumstance that, with notice or the lapse of time, or both, would
result in a default), or the creation of an Encumbrance pursuant to, or cause
or permit the acceleration prior to maturity of any amounts owing under, any
indenture, mortgage, deed of trust, lease, or other agreement to which Berry
is a party, in each case, which failure, violation, conflict or breach would,
in the aggregate, materially hinder or impair the consummation of the
transactions contemplated by this Agreement.  The issuance of the Warrants in
accordance with this Agreement has been duly authorized by all necessary
corporate action on the part of Berry. 
  
            4.3  Consents.  Except as otherwise disclosed in the Berry
Disclosure Letter, no consent, approval or authorization of, or exemption by,

Agreement or the taking of any other action contemplated hereby.

            4.4  Litigation.  There is no legal, judicial, administrative or

effect, or Berry's Certificate of Incorporation or Bylaws for the consummation
of the transactions contemplated by this Agreement.

            From and after the date of this Agreement until the Closing, except
as expressly authorized by this Agreement or expressly consented to in writing
by Berry, Tannehill covenants and agrees with Berry as follows:

            5.1  Access to Tannehill.  Tannehill shall afford to Berry and to
the employees, agents, lenders, investors and authorized representatives of
Berry and to their respective counsel and accountants such reasonable access to
the Assets, officers, offices, equipment, files, agreements, documents, and
books and records of Tannehill (including, without limitation, engineering data
and information, computer programs, tapes and other records), and the
opportunity to make notes, abstracts and copies therefrom, as may be requested
by Berry in order that Berry may have full opportunity to make such reasonable
investigations as it shall desire with respect to the business, operations,
Assets and affairs of Tannehill in connection with the transactions
contemplated hereby and Tannehill shall furnish Berry with such additional
financial and operating data and other information as to the business,
operations and Assets of Tannehill as Berry shall, from time to time,
reasonably request for such purpose.  Berry hereby releases Tannehill from all
liability arising out of the entry by Berry or its employees, agents, lenders,
investors or authorized representatives onto the business premises of Tannehill
for purposes of conducting the investigation contemplated by this Section 5.1.
Berry hereby agrees to indemnify, defend and hold harmless Tannehill against
all liability, demands, claims, costs, losses, damages, recoveries, settlements
and expenses incurred by Tannehill arising from or related to the conduct by
Berry or its employees, agents, lenders, investors or authorized
representatives of the investigation. 

            5.2  Governmental Approvals; Consents.
  
                 a.   Tannehill shall use its best efforts, and shall cooperate
with Berry, to obtain all permits, approvals and consents, and to make all
filings, necessary or required to be obtained or made, and to begin and cause
all waiting periods required to lapse, for Berry to have full use and
enjoyment of the Assets subsequent to the purchase and sale and for the
consummation by Tannehill of the transactions contemplated by this Agreement
under any applicable federal law or the applicable laws of any state having
jurisdiction over the transactions contemplated hereby (all such permits,
approvals, filings and consents and the lapse of all such waiting periods being
referred to as the "Requisite Regulatory Approvals").
 
                 b.   Tannehill shall use its best efforts to obtain all
consents, approvals, clearances, waivers, orders or authorizations of any
Person necessary to be obtained by Tannehill for Berry to have full use and
enjoyment of the Assets subsequent to the purchase and sale and for the
consummation of the transactions by Tannehill contemplated by this Agreement.

            5.3  Litigation and Claims.  Tannehill shall promptly inform Berry
in writing of any litigation, or of any claim or controversy or contingent
liability of which Tannehill


<PAGE> 20
becomes aware that might reasonably be expected to become the subject of
litigation, against Tannehill Oil or affecting any of the Assets.

            5.4  Notice of Changes.  Tannehill shall promptly inform Berry in
writing if Tannehill becomes aware of any change that shall have occurred or
that shall have been threatened (or any development that shall have occurred
or that shall have been threatened involving a prospective change) in the
financial condition, results of operations, business of the Assets or of
Tannehill Oil that is or with the exercise of reasonable business judgment
would be expected to have an adverse effect on the Assets.  Tannehill shall
promptly inform Berry in writing if any representation or warranty made by
Tannehill in this Agreement shall cease to be accurate or upon the occurrence 
of any breach of any covenant or other agreement required by this Agreement to
be performed or complied with by Tannehill.
  
            5.5  Conduct of Business Operations.  Tannehill shall not, without
the prior written consent of Berry:
  
                 a.   Materially increase the annual level of compensation of
any employee, nor increase at all the annual level of compensation of any
employee whose compensation from Tannehill Oil during the last preceding fiscal
year exceeded Fifty Thousand Dollars ($50,000), and shall not grant any unusual
or extraordinary bonuses, benefits or other forms of direct or indirect
compensation to any employee, officer, partner or consultant except in keeping
with past practices by formulas or otherwise.  Nothing in this paragraph 5.5a
shall prohibit the payment by Tannehill of severance payments, accrued and
unpaid vacation pay, or payments in lieu of compensatory time-off to its
employees; 

                 b.   From the Effective Date to the Closing, fail to use its
best efforts to prevent the daily production averaged over any calendar week
during the period from declining below one thousand three hundred (1,300) 
barrels per day.
  
                 c.   Other than in the ordinary course of business, sell,
lease or otherwise dispose of any Assets or any interests therein, or enter
into, or consent to the entering into of, any agreement granting to any third
Person a right to purchase, lease or otherwise acquire any Assets or interests
therein, except as otherwise provided for in this Agreement;

                 d.   Enter into any agreement or incur any obligation, the
terms of which would be violated by the consummation of the transactions
contemplated by this Agreement; 
  
                 e.   Organize, invest in or acquire an equity interest in any
corporation, partnership, joint venture, association or other entity or
organization;

                 f.   Create, incur, assume, guarantee or otherwise become
liable or obligated with respect to any indebtedness for monies borrowed or make
any loan or advance to any Person (other than trade receivables in the ordinary
course of business);



<PAGE> 21
                 g.   (i) Enter into any new line of business with respect to
the Assets; (ii) change its investment, liability management and other material
policies in any respect; (iii) incur or commit to any capital expenditures or
financing; (iv) acquire or agree to acquire by merging or consolidating with,
or acquire or agree to acquire by purchasing all or substantially all of the
assets of, or in any manner, any Person; (v) otherwise acquire or agree to
acquire any assets for a total consideration in the aggregate in excess of Ten
Thousand Dollars ($10,000); or (vi) waive any right under or cancel any
contract, debt or claim listed in any exhibits hereto or the Tannehill
Disclosure Letter, which waiver or cancellation would have an adverse effect on
the Assets;

                 h.   Enter into any contract, commitment or arrangement (or
amend, modify, supplement or otherwise alter the terms of any existing
contract, agreement or instrument attached to the Tannehill Disclosure Letter)
with any Person;

                 i.   Maintain its books of account other than in the usual,
regular and ordinary manner in accordance with good business practices or make
any change in any of its accounting methods or practices; or 

                 j.   Take any action that would or might reasonably be
expected to result in any of the conditions to Closing set forth in Article VII
hereof not being satisfied.

            5.6  Maintain Assets and Operations.  During the period from the
date hereof through the Closing, Tannehill shall (a) carry on its business in
the usual, regular and ordinary course in a good and diligent manner consistent
with sound business practices and in compliance with all applicable laws, rules
and regulations; (b) not introduce any new method of management or operation;
(c) use its best efforts to preserve its business organization, maintain its
rights and franchises, keep available the services of its officers and
employees and preserve the goodwill and its relationships with customers,
suppliers and others having business dealings with it; (d) preserve in full
force and effect all leases, operating agreements, easements, rights of way,
permits, licenses, contracts and other agreements which relate to the Assets
(other than those expiring by their terms); (e) use its best efforts to perform
or cause to be performed all of its obligations in or under any of such leases,
agreements and contracts; (f) use its best efforts to safeguard and maintain
secure all reports and other confidential data in the possession of Tannehill
relating to the Assets; and (g) use its best efforts to operate its business
and activities in the same manner as they have been carried out and to maintain
the same level of expenditure as have previously been incurred in connection
with such business and activities.
 
            5.7  Exclusive Dealing.  Tannehill shall not directly or
indirectly, through any representative or otherwise, solicit or entertain
offers from, negotiate with or in any manner encourage, discuss, accept or
consider any proposal of any Person relating to the acquisition of the assets
or business, in whole or in part, of Tannehill, whether through direct
purchase, consolidation or other business combination (other than sales of
inventory or in the ordinary course of business) so long as this Agreement has
not been terminated.  Tannehill recognizes that Berry has and continues to
incur substantial time and expense in evaluating this transaction.  Tannehill
acknowledges that Berry, in reliance on this Section 5.7, will continue to
incur


<PAGE> 21A
additional time, effort and expense.  Tannehill has agreed to this provision
due to the unique terms specified in the AIP and contemplated in this
transaction.
 
            5.8  Termination Fee.  In the event that Tannehill breaches Section
5.7 hereof and within twelve (12) months after such breach or termination,
Tannehill closes a transaction with an unrelated third party relating to the
acquisition of a Material portion of the Assets or the business of Tannehill
Oil, in whole or part, whether through direct purchase, merger, consolidation
or other business combination (other than sales of inventory or immaterial
portions of Tannehill's Assets in the ordinary course), then, immediately upon
such closing, Tannehill shall pay to Berry the sum of Two Million Three Hundred
Eighty Thousand Dollars ($2,380,000).  Such payment shall constitute liquidated
damages and, in the absence of fraud or bad faith, shall be in lieu of any
other penalty or remedy Berry might otherwise seek, the parties having
determined that the actual damages resulting from the events for which such



<PAGE> 22
liquidated damages are to be awarded would be extremely difficult and uncertain
to calculate and that liquidated damages above represent a good faith estimate
of such actual damages.

necessary to approve this Agreement.
  
  
                              ARTICLE VI
                          COVENANTS OF BERRY
  
  
            Berry hereby covenants and agrees with Tannehill as follows:
  
            6.1  Cooperation.  Subject to the terms and conditions of this
Agreement, Berry shall cooperate with Tannehill to use its best efforts to
secure all necessary consents, approvals, authorizations, exemptions and
waivers from all Persons and Governmental Entities as shall be required to be
obtained by Berry in order to enable Berry to consummate the transactions
contemplated hereby.
 
            6.2  Governmental Approvals.  Berry shall use its best efforts, and
shall cooperate with Tannehill, to obtain all Requisite Regulatory Approvals.

            6.3  Disclosure Responsibilities.  Berry, as a reporting company
under Section 12 of the Securities Exchange Act of 1934, as amended ("Exchange
Act"), and listed company under the New York Stock Exchange (the "NYSE"), is
required to comply with certain disclosure requirements regarding its business
activities, including, but not limited to, the issuance of press releases and
the preparation and filing of periodic reports with the Securities and Exchange
Commission.  In order to comply with the disclosure requirements of the
Exchange Act and NYSE, as well as the timing of such disclosures, all
statements to the public, including press releases, shall be at the sole
discretion of Berry.



<PAGE> 23
          6.4  Authorization of Warrant.  Berry shall take all actions to
qualify the issuance of the Warrant to Tannehill Oil in compliance with all
applicable state securities laws or to comply with any available exemptions
from such qualification requirements.  However, Berry shall not be obligated to
register the Warrant, or the shares of Class A Common Stock underlying the
Warrant, under the Securities Act of 1933.

            6.5  Cooperation in Exchange.  Berry will cooperate with Tannehill
in the completion of one or more tax-deferred exchange transactions and shall
execute such documents as are reasonably required for that purpose, provided
that Berry shall not be required to take title to any other property, shall not
be put at any extra cost or expense, shall not be subject to any additional
liability, and the date for the Closing shall not be extended by virtue of any
requested cooperation.
  
  
                             ARTICLE VII
                  CONDITIONS TO OBLIGATIONS OF BERRY
  
  
            The obligations of Berry to consummate the transactions
contemplated by this Agreement shall be subject to the satisfaction (or waiver
by Berry) on or prior to the Closing of all of the following conditions:

            7.1  Accuracy of Representations and Warranties.  The
representations and warranties of Tannehill set forth in this Agreement shall
be true and correct in all respects as of the date when made and at and as of
the Closing.
 
            7.2  Performance of Covenants and Agreements.  Tannehill shall have
duly performed and complied in all respects with the covenants, agreements and
conditions required by this Agreement to be performed or complied with by them
prior to or at the Closing.  None of the events or conditions entitling Berry
to terminate this Agreement under Article IX hereof shall have occurred and be
continuing.
 
            7.3  Consents.  Any consent required for the consummation of this
purchase and sale under any agreement, contract, license or other instrument
described in any exhibit hereto or referred to herein, or for the continued
enjoyment by Berry of any benefits of such agreement, contract, license or
other instrument after the Closing, which consent Tannehill is specifically
obligated to obtain pursuant to this Agreement, shall have been obtained and be
effective.
 
            7.4  Governmental Approvals.  All Requisite Regulatory Approvals
shall have been obtained, made or lapsed and shall be in full force and effect.

            7.5  Approval of Counsel.  The form and substance of all legal
matters contemplated hereby and all papers delivered hereunder shall be
reasonably acceptable to Nordman, Cormany, Hair & Compton, counsel to Berry.



<PAGE> 24 
            7.6  Partners' Certificate.  Berry shall have received a
certificate of Tannehill Oil, substantially in the form of Exhibit 13 attached
hereto and made a part hereof, satisfactory in form and substance to Berry,
executed on behalf of Tannehill Oil by its Managing General Partners, as to
compliance with the matters set forth in Sections 7.1, 7.2, 7.3 and 7.4 of this
Agreement.  By signing this Agreement, each of the Partners hereby authorizes
the Managing General Partners of Tannehill Oil to execute such Certificate.
 
            7.7  Opinion of Counsel.  Berry shall have received the opinion of
Roger Coley, counsel to Tannehill, in form and content satisfactory to Berry,
substantially in the form of Exhibit 14 attached hereto and made a part hereof.
  
            7.8  Closing of TEC and TOC Purchase Agreements.  The Closing shall
not occur unless the Closings contemplated by the TEC Purchase Agreement and
the TOC Purchase Agreement have occurred or will occur concurrently with the
Closing.
 
            7.9  Condition of Real Property.  Berry shall have approved title
to and the condition of the Real Property as follows:

                 a.   A current CLTA Preliminary Title Report prepared by First
American Title Company covering the Real Property, accompanied by legible
copies of all documents referred to as exceptions in the report to the extent
reasonably available through Tannehill's best efforts [and a map plotting all
easements] (the "PTR"), has been delivered to Berry.
  
                 b.   If Berry elects to obtain an ALTA Policy, a survey of the
Real Property shall have been prepared, at Berry's expense, by a licensed
surveyor or registered civil engineer, in sufficient detail to provide for the
policy of title insurance to be purchased by Berry, certified to Berry in a
form satisfactory to Berry, without boundary, encroachment or survey exceptions
and which shows the location of all easements and improvements.  It shall be
Berry's sole responsibility to obtain such survey by the Title Approval Date
defined below.  Berry's failure to do so will be deemed Berry's waiver of this
condition.  If Berry does not elect to obtain an ALTA Policy, then Tannehill
shall provide Berry with a CLTA Policy at Tannehill's expense.
 
                 c.   Title shall be free of Encumbrances not approved by
Berry.  On or before November 8, 1996 (the "Title Approval Date"), Berry shall
advise Tannehill in writing of what exceptions to coverage, if any, are
unacceptable to Berry (the "Title Disapproval Notice").  Notwithstanding any
other provision of this Section 7.9, Berry hereby objects to all monetary
Encumbrances, which monetary Encumbrances (if any) Tannehill shall cause to be
eliminated at the Closing except for non-delinquent real property taxes and
assessments, which shall be one of the exceptions to coverage.  Tannehill shall
have ten (10) business days after receipt of a Title Disapproval Notice to give
Berry notice either:  (i) that Tannehill will remove, on or before the Closing,
any disapproved exceptions to coverage and provide Berry with evidence
satisfactory to Berry of such removal; or (ii) that Tannehill elects not to
cause such exceptions to coverage to be removed, in which case Berry shall have
five (5)


<PAGE> 25
business days thereafter to notify Tannehill in writing of Berry's election
(a) to waive any objectionable exceptions and to proceed with the purchase of
and to take the Real Property subject to such exceptions, but otherwise
pursuant to the terms of this Agreement, or (b) to terminate this Agreement.
If Berry shall fail to give Tannehill notice of such election within said five
(5) business days, Berry shall be deemed to have elected to waive its objection
to the coverage and to proceed with this purchase.  In the event that during 
escrow any amended or supplemented PTR is issued disclosing new exceptions to
coverage, Berry shall again have the right to give a Title Disapproval Notice
as to such new exception, in which case all the foregoing rights of the parties
following the giving of such a notice shall again apply as stated above.

                 d.   Berry shall not have given written notice of disapproval
of matters related to the Real Property.  Berry's failure to give written
notice of disapproval on or before November 8, 1996 (the "Property Approval
Date") of all aspects and matters related to the Real Property, including size,
shape, configuration, access, easements (express, implied and by prescription),
geologic/subsidence and soil conditions, hydrologic conditions, water supply
quantity and quality, buildings, tanks, pipelines, oil and gas wells, oils and
gas surface equipment, and the condition of all other fixed equipment shall be
deemed approval of matters relating to the Real Property.  To facilitate
Berry's review, Tannehill shall deliver to Berry within fifteen (15) business
days after the date of this Agreement, (i) any environmental reports prepared
by or for Tannehill covering all or any portion of the Real Property, without
representation or warranty as to their accuracy or validity; (ii) copies of any
service contracts now in effect, all of which are cancelable at any time, or by
the giving of not more than thirty (30) days' notice; and (iii) any well logs
and reports of water usage made to the Regional Water Quality Control Board,
the Division of Oil, Gas and Geothermal Resources and other agencies, as
applicable.

                 e.   Berry shall be satisfied that there are no Hazardous
Materials, as that term is defined by all or any applicable laws, on the Real
Property or in the groundwater thereunder and Berry's acceptance and approval
of an Environmental Audit and Assessment ("Phase I Report") as to the Real
Property performed at Berry's direction and sole cost and expense.  Berry's
failure to give notice of disapproval of the Phase I Report obtained by Berry,
if any, on or before the Property Approval Date shall be deemed as Berry's
approval thereof and acceptance of the Real Property in its present condition.
In the event such Phase I Report or any Phase II Report involving soil and/or
groundwater tests, approved in advance by Tannehill, discloses that the Real
Property or groundwater thereunder is contaminated with Hazardous Materials in
quantities requiring remediation or removal under existing law, Berry shall
have the right to terminate this Agreement.  Except as provided in the
succeeding sentence, Berry agrees that the Phase I Report and any other report,
tests, and information and conclusions stated therein shall be kept
confidential and that any reporting requirements to any governmental agency or
any other third party arising therefrom shall be the sole responsibility of
Tannehill.  Notwithstanding the foregoing, in the event that any then
applicable law, statute or ordinance requires Berry to report or disclose the
Report or Report findings to a governmental agency, then and only then shall
Berry disclose the Report findings.  In no event shall Berry be entitled


<PAGE> 26
to conduct any soil borings or groundwater tests without Tannehill's prior
written approval, which may be conditioned or denied in Tannehill's sole
discretion.

                 f.   Berry shall have received an affidavit, certification or
notice required by Section 1445 of the Code and the Regulations pursuant
thereto.  In addition, Tannehill shall have provided Berry with the
certification required to show that withholding is not required pursuant to
California Revenue and Taxation Code Section 18662(e).  In the event any of the
Partners does not qualify for the exemption from withholding under Section
1445(e) of the Code or Section 18662(e) of the California Revenue and Taxation
Code, Berry will comply with the withholding requirement of such sections.

            7.10 Termination of Operating Agreement.  That certain Operating
Agreement and First Amendment to Operating Agreement, dated January 1, 1992,
entered into by and between Tannehill Oil and the Partners shall be cancelled,
in writing, by the parties thereto at the Closing.

  
                             ARTICLE VIII
                CONDITIONS TO OBLIGATIONS OF TANNEHILL
  
  
            The obligations of Tannehill to consummate the transactions
contemplated by this Agreement shall be subject to the satisfaction (or waiver
by Tannehill) on or prior to the Closing of all of the following conditions:
  
            8.1  Accuracy of Representations and Warranties.  The
representations and warranties of Berry set forth in this Agreement shall be
true and correct in all material respects as of the date when made and at and
as of the Closing.
  
            8.2  Performance of Covenants and Agreements.  Berry shall have
duly performed and complied in all respects with the covenants, agreements and
conditions required by this Agreement to be performed or complied with by it

            9.1  Termination.  This Agreement may be terminated at any time

                              ARTICLE X
                           INDEMNIFICATION
  
  
            10.1 Indemnification by Berry.  Berry agrees to indemnify, defend
and hold Tannehill, and agents of Tannehill, harmless from and against any and
all loss, liability, damage, costs and expenses (including interest, penalties,
settlements, fines, costs and expenses incurred in connection with
investigating and defending any claims or causes of action, and reasonable
attorneys' fees) that Tannehill and its agents may incur or become subject to
arising out of or due to any inaccuracy of any representation or the breach of
any warranty, covenant, undertaking or other agreement of Berry contained in
this Agreement.
 
            10.2 Indemnification by Tannehill.  Tannehill, jointly and
severally, agrees to indemnify, defend and hold Berry, and the officers,
directors, employees and agents of Berry (collectively, the officers,
directors, employees and agents being referred to in each case as its "Related
Parties") harmless from and against any and all loss, liability, damage, costs
and expenses (including interest, penalties, settlements, fines, costs and
expenses incurred in connection with investigating and defending any claims or
causes of action, and reasonable attorneys' fees) that Berry and its Related
Parties may incur or become subject to arising out of or due to any inaccuracy
of any representation or the breach of any warranty, covenant, undertaking or
other agreement of Tannehill contained in this Agreement.  Tannehill, jointly
and severally also agrees to indemnify, defend and hold Berry and its Related
Parties harmless from and against any and all loss, liability, damage, costs
and expenses (including interest, penalties, settlements, fines, costs and
expenses incurred in connection with investigating and defending any claims or
causes of action, and reasonable attorneys fees) that Berry and its Related
Parties may incur or become subject to arising out of the Baker Litigation or
attributable to any environmental conditions caused directly or indirectly by
the acts of or failure to act by Baker Chemical and/or its officers, employees
or agents.

            10.3 Survival.  The several warranties, representations, covenants
and agreements of the parties contained in this Agreement and in any other
instrument delivered pursuant hereto shall survive the Closing and shall remain
in full force and effect thereafter.

            10.4 Notice and Opportunity to Defend.
  
                 a.   If a party seeking indemnification (the "Indemnitee")
becomes aware of any matters that it believes may give rise to an indemnifiable
claim, or asserts any claim that it believes may be indemnifiable pursuant to
this Agreement, the Indemnitee shall give the party obligated to provide
indemnification (the "Indemnifying Party") prompt written notice of such matter
or claim, stating with particularity the nature of such matter or the
aforementioned claim and the amount thereof.  Failure to provide such notice
shall not affect the


<PAGE> 29
right of the Indemnitee to indemnification except to the extent such failure
shall have resulted in liability to the Indemnifying Party that could have been
actually avoided had such notice been provided within such required time
period.

                 b.   If the matter that the Indemnitee believes gives rise to
an indemnifiable claim does not involve a third party claim against an 
ndemnitee, the Indemnifying Party shall have thirty (30) days from the date on
which it received notice of such claim pursuant to this Section to respond to
such notice.  If such Indemnifying Party accepts responsibility or does not
respond within such thirty (30)-day period, the Indemnifying Party shall
promptly pay to the Indemnitee the full amount of such claim.  If the
Indemnifying Party rejects any liability with respect to such claim, it shall
give written notice of such objection to the Indemnitee within such thirty
(30)-day period and the parties shall seek to resolve such claim by agreement.
If the parties are unable to resolve such claim by agreement within sixty (60)
days following the expiration of such thirty (30)-day period mentioned above,
the parties shall be entitled to pursue, without prejudice to any of their
rights hereunder, such remedies as may be available to the parties under
applicable law.

                 c.   In the event any action, suit, proceeding or investigation
is brought against the Indemnitee by a third party which the Indemnitee
believes may give rise to an indemnifiable claim, the Indemnitee shall
give the Indemnifying Party prompt written notice of the commencement of such
action, suit, proceeding or investigation as provided in paragraph a. of this
Section.  Such Indemnifying Party shall have a period of thirty (30) days after
receipt of such notice within which to respond to such notice.  If such 
Indemnifying Party does not respond within such thirty (30)-day period or
rejects responsibility for such matter in whole or in part, the Indemnitee
shall be free to pursue, without prejudice to any of its rights hereunder, such
remedies as may be available to such party under applicable law.  If such
Indemnifying Party accepts responsibility, such Indemnifying Party shall, as
between the Indemnitee and the Indemnifying Party, be obligated to compromise
or defend such matter, at its own expense.  The Indemnitee shall employ counsel
of its choice and the Indemnifying Party shall reimburse Indemnitee for
attorneys' fees and costs.  The Indemnifying Party shall cooperate fully with
the Indemnitee and its counsel in the defense against any such asserted
liability.  Any compromise of such asserted liability by the Indemnitee shall
require the prior written consent of the Indemnifying Party, which shall not be
unreasonably withheld.  If, however, the Indemnitee refuses its consent to a
bona fide offer of settlement that involves solely the payment of cash that the
Indemnifying Party wishes to accept, the Indemnitee may continue to pursue such
matter, free of any participation by the Indemnifying Party, at the sole
expense of the Indemnitee.  In such event, the obligation of the Indemnifying
Party to the Indemnitee shall be equal to the lesser of (i) the amount of the
offer of settlement that the Indemnitee refused to accept plus the costs and
expenses of the Indemnitee prior to the date the Indemnifying Party notified
the Indemnitee of the offer of settlement; and (ii) the actual out-of-pocket
amount the Indemnitee is obligated to pay as a result of such party's
continuing to pursue such matter.  An Indemnifying Party shall be entitled to
recover from the Indemnitee any additional expenses incurred by such
Indemnifying Party as a result of the decision of the Indemnitee to pursue
such matter.



<PAGE> 30
            10.5 General.  The indemnification provided in this Agreement shall
apply regardless of whether the matter subject to indemnification involved an
action taken or omitted that was negligent, grossly negligent or reckless by
the Person to be so indemnified.  It is understood that such indemnification is
intended to be a means of compensating the parties for any damage or liability
directly or indirectly realized by them for matters subject to such 
indemnification.  To the extent the indemnification provided for herein may not
be provided to any Person under law, such indemnification shall be required to
be provided to any other Person for whom such indemnification may be
permissible as herein provided.

necessary, proper or advisable under applicable laws and regulations to

provision of this Agreement is invalid, illegal or incapable of being enforced
by any rule of law, or public policy, all other conditions and provisions of

economic and legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party.  Upon such
determination that any term or other provision is invalid, illegal or incapable
of being enforced, the parties hereto shall negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that transactions contemplated
hereby are fulfilled to the extent possible.

            11.6 Attorneys' Fees.  In the event of any claim, dispute or
controversy arising out of or relating to this Agreement, including an action
for declaratory relief, the prevailing party in such action or proceeding shall
be entitled to recover its taxable costs or arbitration fees, and reasonable
out-of-pocket expenses, including but not limited to, telephone calls,
photocopies, expert witnesses, travel, computer expenses related to litigation,
and attorneys' fees to be fixed by the court or the arbitrator.  Such recovery
shall include court costs, out-of-pocket expenses and attorneys' fees on
appeal, if any.  The court shall determine who is the "prevailing party,"
whether or not the dispute or controversy proceeds to final judgment.

            11.7 Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original
and all of which shall constitute the same instrument.
 
            11.8 Headings.  The headings of the articles, sections and

                          November 14, 1996
  
  
       THIS CERTIFIES THAT, for value received, TANNEHILL OIL COMPANY, a

represented by the shares of Common Stock of the Company authorized as of the
date hereof.

       This Warrant is subject to the following terms and conditions:
  
       1.   Exercise of Warrant.  The purchase rights represented by this 
Warrant are exercisable at the option of the holder hereof, in whole at any
time, or in part from time to time (but not as to a fractional share of Common
Stock) during the Exercise Period (as defined below).  In the case of the
purchase of less than all the shares purchasable under this Warrant, the
Company shall cancel this Warrant upon the surrender hereof and shall execute
and deliver a new Warrant of like tenor for the balance of the shares
purchasable hereunder.  The term "Exercise Period" shall mean and refer to the
period commencing on the date hereof and ending on November 8, 2003.
 
       2.   Price.  The purchase price for each share of Common Stock
purchasable pursuant to the exercise of this Warrant (the "Exercise Price")
shall be equal to the Market Value (as defined below), plus two dollars ($2.00)
per share in funds of the United States of America (or shall be such other
amount per share if and as adjusted as provided in Section 3 below).  The term
"Market Value" shall mean the average closing price per share of Class A Common
Stock traded on the New York Stock Exchange for the twenty (20) trading days
prior to the trading day before the closing of the transactions contemplated by
the Agreement (the "Closing").  For example, assuming the respective closing
prices of the Class A Common Stock for the twenty (20) trading days prior to
Closing are as follows:
 
            10/15          $11-1/2        10/3      $11
            10/14          $11-1/2        10/2      $11-1/2
            10/11          $11-3/4        10/1      $11-3/4
            10/10          $11-3/4        9/30      $12
            10/9           $11-1/2        9/27      $12
            10/8           $11            9/26      $11-3/4
            10/7           $11-1/4        9/25      $11-1/2
            10/6           $11            9/24      $11-1/2
            10/5           $11-3/4        9/23      $11-1/4
            10/4           $11-1/2        9/22      $11-1/4
  
the aggregate total of the closing prices is 230 and the average closing price
per share is equal to 11.5 (i.e., 230 / 20).

          3.   Adjustments to Exercise Price and Number of Shares.
  
            3.1  The Exercise Price and number of shares of Common Stock
purchasable pursuant to the exercise of this Warrant shall be subject to
adjustment from time to time as follows:

                 a.   Adjustment for Combinations or Consolidations of Common
Stock.  In the event the Company, at any time after the date hereof (hereinafter
referred to as the "Original Issue Date"), effects a subdivision or combination
of its outstanding Common Stock into a greater or lesser number of shares, then
and in each such event, the Exercise Price and the number of shares of Common
Stock purchasable pursuant to the exercise of this Warrant shall be decreased or
increased, respectively, proportionately.

                 b.   Adjustment for Certain Dividends and Distributions. In
the event the Company at any time after the Original Issue Date shall make or
issue, or fix a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, then and in each such event the maximum number of
shares (as set forth in the instrument relating thereto without regard to any
provisions contained therein for a subsequent adjustment to such number) of
Common Stock issuable in payment of such dividend or distribution shall be
deemed to be issued and outstanding as of the time of such issuance or, in the
event such a record date shall have been fixed, as of the close of business on
such record date.  In each such event, the Exercise Price shall be decreased as
of the time of such issuance or, in the event such a record date shall have been
fixed, as of the close of business on such record date, by multiplying the
Exercise Price by a fraction, 

            (1)  the numerator of which shall be the total number of shares of
     Common Stock issued and outstanding or deemed to be issued and outstanding
     immediately prior to the time of such issuance or the close of business on
     such record date; and 
  
            (2)  the denominator of which shall be the total number of shares
     of Common Stock issued and outstanding or deemed to be issued and 
     outstanding immediately prior to the time of such issuance or the close of
     business on such record date plus the number of shares of Common Stock
     issuable in payment of such dividend or distribution;

provided, however, that if such record date shall have been fixed and such
dividend not fully paid or if such distribution is not fully made on the date
fixed therefor, the Exercise Price shall be recomputed accordingly as of the
close of business on such record date and thereafter the Exercise Price shall
be adjusted pursuant to paragraph 3.1(b) as of the time of actual payment of
such dividends or distribution.

                 c.   Adjustments for Reclassifications and for Other Dividends
and Distributions.  In the event the Company at any time after the Original
Issue Date shall effect a reclassification of its Common Stock (other than one
resulting in the issuance of additional shares of Common Stock) or shall make
or issue, or fix a record date for the determination of


<PAGE> 4
holders of Common Stock entitled to receive, a dividend or other distribution
to its stockholders payable in securities of the Company other than shares of
Common Stock, then and in each such event provision shall be made so that the
holder of this Warrant shall receive, upon exercise thereof, the securities of
the Company which such holder would have received had this Warrant been
exercised and the Common Stock issuable on exercise been received on the date
of such event. 

            3.2  Upon any adjustment of the Exercise Price and of the number of
shares of Common Stock and, if applicable, other securities and property 
issuable upon exercise of this Warrant, pursuant to this Section 3, the
Company, within twenty (20) days thereafter, shall cause to be prepared a
certificate of the Chief Financial Officer of the Company setting forth the
Exercise Price after such adjustment and setting forth in reasonable detail the
method of calculation used.
  
            3.3  In case:
  
                 a.   The Company shall authorize the issuance to all holders
of Common Stock of rights or warrants to subscribe for or purchase capital
stock of the Company or of any other subscription rights or warrants; or

                 b.   the Company shall authorize the distribution to all
holders of Common Stock of evidences of its indebtedness or assets (other than
cash dividends or cash distributions payable out of consolidated earnings or
earned surplus or dividends payable in Common Stock); or 

                 c.   of any consolidation or merger to which the Company is
a party and for which approval of any stockholders of the Company is required,
or of the conveyance or transfer of the properties and assets of the Company
substantially as an entirety, or of any capital reorganization or any 
reclassification of the Common Stock (other than a change in par value, or from
par value to no par value, or from no par value to par value, or as a result of
a subdivision or combination); or

                 d.   of the voluntary or involuntary dissolution, liquidation
or winding up of the Company; or 

                 e.   the Company proposes to take any other action which would
require an adjustment of the Exercise Price or number or kind of shares
issuable upon exercise of this Warrant, pursuant to this Section 3;

then the Company shall cause to be given to the registered holder of the
outstanding Warrant at its address in the records of the Company at least
thirty (30) calendar days (or fifteen (15) calendar days in any case specified
in paragraph a or b above) prior to the applicable record date hereinafter
specified, by first-class mail, postage prepaid, written notice stating (i) the
date as of which the holders of record of shares of Common Stock to be entitled
to receive any rights, warrants or distribution are to be determined or
(ii) the date on which any consolidation, merger,


<PAGE> 5
conveyance, transfer, reorganization, reclassification, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange the shares for securities or other property, if any,
deliverable upon the consolidation, merger, conveyance, transfer, 
reorganization, reclassification, dissolution, liquidation or winding up.
 
            3.4  Irrespective of any adjustments in the Exercise Price or the
number or kind of shares purchasable upon exercise of the Warrant, the Warrant
theretofore or thereafter issued may continue to express the same price and
number and kind of shares as are stated in the similar Warrant initially
issued.

       4.   Elimination of Fractional Interests.  The Company shall not be
required to issue certificates representing fractions of shares of Common
Stock, but will make a payment in cash based on the Exercise Price in effect at
that time.

       5.   Covenants of the Company.  The Company covenants and agrees that
all shares which may be issued upon the exercise of this Warrant shall, upon
issuance, be duly authorized, validly issued, fully paid and non-assessable and
free from all preemptive rights of any stockholder and all taxes, liens and
charges with respect to the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue).  The Company further
covenants and agrees that during the Exercise Period within which the rights
represented by this Warrant may be exercised, the Company will at all times
have authorized, and reserved, a sufficient number of shares of its Common
Stock to provide for the exercise of the rights represented by this Warrant.

       6.   Restrictions on Transferability of Securities; Compliance with
          Securities Act.
  
            6.1  Restrictions on Transferability.  This Warrant and shares of
Common Stock issuable upon exercise of this Warrant are restricted shares and
shall not be transferable, except upon the conditions specified in this Section
6, which conditions are intended to insure compliance with the provisions of
the Securities Act of 1933, as amended (the "Securities Act").  The holder of
this Warrant shall cause any proposed transferee of this Warrant, or the shares
of Common Stock issuable upon exercise of this Warrant held by that holder, to
agree to take and hold those securities subject to the provisions and upon the
conditions specified in this Section 6.

            6.2  Certain Definitions.  As used in this Section 6, the term
"Restricted Securities" means (i) the Warrants, (ii) the shares of Common Stock
issuable or issued upon exercise of the Warrants, and (iii) any shares of
Common Stock of the Company issued as a dividend or other distribution with
respect to, or in exchange or in replacement of the Warrants or such shares of
Common Stock.

            6.3  Restrictive Legend.  Each certificate representing (i) the
Warrants, (ii) shares of the Company's Common Stock issued upon exercise of the
Warrants, or (iii) any other securities issued in respect of the Warrants or
the Common Stock issued upon exercise of the


<PAGE> 6
Warrants upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall be stamped or otherwise imprinted with a
legend in the following form (in addition to any legend required under
applicable state securities laws): 
 
       THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
       OF 1933, AS AMENDED (THE "SECURITIES ACT"), NOR HAVE THE SECURITIES
       BEEN QUALIFIED UNDER ANY STATE SECURITIES LAWS.  ACCORDINGLY, THE
       SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE UNLESS SUCH
       SECURITIES ARE SUBSEQUENTLY REGISTERED UNDER FEDERAL AND APPLICABLE
       STATE SECURITIES LAWS OR UNLESS EXEMPTIONS FROM REGISTRATION AND
       QUALIFICATION ARE AVAILABLE.
  
                 Upon request of a holder of such a certificate, the Company
shall remove the foregoing legend from the certificate or issue to such holder
a new certificate therefor free of any transfer legend, if, with such request,
the Company shall have received the opinion referred to in Section 6.4 to the
effect that any transfer by such holder of the securities evidenced by such
certificate will not violate the Securities Act and applicable state securities
laws.

            6.4  Notice of Proposed Transfers.  The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in
all respects with the provisions of this Section 6.4.  Prior to any proposed
transfer of any Restricted Securities, the holder thereof shall give written
notice to the Company of such holder's intention to effect such transfer.  Each
such notice shall describe the manner and circumstances of the proposed
transfer in sufficient detail, and shall be accompanied (except in transactions
in compliance with Rule 144) by a written opinion of legal counsel who shall be
reasonably satisfactory to the Company, addressed to the Company and reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, whereupon the holder of such Restricted
Securities shall be entitled to transfer such Restricted Securities in
accordance with the terms of the notice delivered by the holder to the Company.
Each certificate evidencing the Restricted Securities transferred as above
provided shall bear the appropriate restrictive legend set forth in Section 6.3
above, except that such certificate shall not bear such restrictive legend if
the opinion of counsel letter referred to above is to the further effect that
such legend is not required in order to establish compliance with any provision
of the Securities Act.
  
            6.5  Reports Under Securities Exchange Act of 1934.  With a view to
making available to the holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the Commission that may at
any time permit a Holder to sell securities of the Company to the public
without registration, the Company agrees to use its best efforts to:
 
                 a.   make and keep public information available (as provided
in Rule 144) at all times;



<PAGE> 7
                 b.   file with the Commission in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934 (the "Exchange Act"); and

                 c.   furnish to any Holder so long as such Holder owns any of
the Restricted Securities upon request a written statement by the Company that
it has complied with the reporting requirements of Rule 144 and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents so filed
by the Company as may be reasonably requested in availing any holder of any
rule or regulation of the Commission permitting the selling of any such
Restricted Securities without registration.

       7.   Exchange and Replacement of Warrant.  Upon receipt by the Company
of evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and, in case of loss, theft or destruction, of an
indemnity agreement or bond reasonably satisfactory to it, and reimbursement to
the Company of all reasonable expenses incidental thereto, and upon surrender
and cancellation of this Warrant, if mutilated, the Company will make and
deliver a new Warrant of like tenor, in lieu of this Warrant.

       8.   Rights Prior to Exercise of Warrant.  Prior to the exercise of this
Warrant, the holder of this Warrant shall not be entitled to any rights of a
stockholder of the Company, including without limitation the right to vote, to
receive dividends or other distributions or to exercise any preemptive rights,
as to those shares of Common Stock subject to this Warrant, and shall not be
entitled to receive any notice of any proceedings of the Company except as
provided herein.
 
       9.   Notices.  Any and all notices, demands, requests or other
communications required or permitted by this Warrant or by law to be served on,

    Re:  Berry Petroleum Company / Tannehill Oil Company, 
          Asset Purchase and Sale Transaction

Gentlemen:
  
     We have acted as counsel to Tannehill Oil Company, a California general
partnership ("Tannehill"), and individuals and entities that are partners of
Tannehill Oil Company (the "Partners"), in connection with the sale of
substantially all the assets of Tannehill and certain undivided mineral 
interests of the Partners to Berry Petroleum Company, a Delaware corporation
("Berry"), pursuant to that certain Purchase and Sale Agreement, dated
______________, 1996, by and between Tannehill, the Partners and Berry
(the "Agreement"). 

     In rendering the opinions set forth below, we have assumed the due
authorization, execution and delivery of the Agreement by Berry.

     Based on the foregoing, and in reliance thereon, but subject to the
qualifications herein set forth, we are of the opinion that:

     1.   Tannehill is a general partnership duly organized and validly
existing under, and by virtue of, the laws of the State of California and
is in good standing under such laws.  Tannehill has requisite power to own and
operate its properties and assets, and to carry on its business as presently
conducted.
 
    2.   Tannehill and the Partners have full power and authority to execute
and deliver the Agreement and to perform their obligations under the terms of
the Agreement.
 
     3.   All partnership action on the part of Tannehill and its Partners
necessary for the authorization, execution, delivery and performance of the
Agreement, and the consummation of the transactions contemplated thereby, has
been taken.  The Agreement has been duly executed


<PAGE> 2
and delivered by Tannehill and its Partners and constitutes a legal, valid and
binding obligation of Tannehill and its Partners, enforceable against them in
accordance with its respective terms, except as such enforceability may be
limited by or subject to (a) any bankruptcy, insolvency, reorganization,
moratorium or similar laws relating to creditor's rights generally and 
(b) general principles of equity (regardless of whether such enforceability
is considered in a proceeding in equity or at law).

     4.   The Partners executing the Agreement are the beneficial owners of an
aggregate of one hundred percent (100%) of the partnership interests in 
Tannehill (the "Partnership Interests").  There are no outstanding options,
warrants, rights of first refusal, or other rights calling for the issuance of,
or any security convertible into or exchangeable for, Partnership Interests and
no other person or entity has any right in or to the Partnership Interests.

     5.   No consent, approval or authorization of or designation of Tannehill
or the Partners is required in connection with the valid execution and delivery
of the Agreement, or the consummation of the transactions contemplated thereby
on the Closing thereof, except as such have been obtained or made prior to or
upon the date hereof.

     6.   To our best knowledge, no default exists and no event has occurred
which would constitute a default under, or violation in the due performance and
observance of any term, covenant or condition, or breach of, Tannehill's
Partnership Agreement or any indenture, license, lease, franchise, mortgage,
instrument, or other agreement to which Tannehill or its Partners are a party,
or by which Tannehill or its Partners or their properties may be bound; or (a)
an event that would permit any party to any agreement or instrument to 
terminate it or to accelerate the maturity of any indebtedness or other
obligation of Tannehill or its Partners; (b) an event that would result in the
creation or imposition of any lien, charge, or encumbrance on any asset of 
Tannehill or its Partners; or (c) an event that would conflict with any order,
rule, or regulation directed to Tannehill or its Partners by any court or 
governmental agency or body having jurisdiction over it.
 
     7.   Except as disclosed in the Tannehill Disclosure Letter (as defined
in the Agreement), to our best knowledge, there is no suit, action,
arbitration, or legal, administrative, or other proceeding or governmental
investigation pending or threatened against or affecting Tannehill or its
Partners or any of their businesses or properties or financial or other 
condition.

     8.   Except as disclosed in the Tannehill Disclosure Letter, there are no
agreements, written or oral, between Tannehill or its Partners and any other
party that affect, directly or indirectly, the Assets (as defined in the 
Agreement).
 
     We are members of the bar of the State of California, and accordingly we
do not purport to be experts on, or to be qualified to express any opinion
herein concerning, nor do we express any opinions herein concerning, any law
other than federal law and the laws of the State of California.

       Re:  Berry Petroleum Company / Tannehill Oil Company, 
            Asset Purchase and Sale Transaction

Gentlemen:
  
     We have acted as counsel to Berry Petroleum Company, a Delaware 
corporation ("Berry"), in connection with the purchase of substantially all the
assets of Tannehill Oil Company, a California general partnership, and certain
undivided mineral interests from individuals and entities that are partners of
Tannehill Oil Company (collectively, "Tannehill"), by Berry, pursuant to that
certain Purchase and Sale Agreement, dated ______________, 1996, by and between
Tannehill and Berry (the "Agreement").
  
     In rendering the opinions set forth below, we have assumed the due 
authorization, execution and delivery of the Agreement by Tannehill. 
  
     1.   Berry is a corporation duly organized and validly existing under, and
by virtue of, the laws of the State of Delaware and is in good standing under
such laws.  Berry has requisite corporate power to own and operate its
properties and assets, and to carry on its business as presently conducted.
  
     2.   Berry has full corporate power and authority to execute and deliver
the Agreement and to perform its obligations under the terms of the Agreement.
  
     3.   All corporate action on the part of Berry necessary for the 
authorization, execution, delivery and performance of the Agreement and the
consummation of the transactions contemplated thereby, has been taken.  The
Agreement has been duly executed and delivered by Berry and constitutes a
legal, valid and binding obligation of Berry, enforceable against it in

limited by or subject to (a) any bankruptcy, insolvency, reorganization, 
moratorium or similar laws relating to creditor's rights generally and
(b) general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).
  
     4.   No consent, approval or authorization of or designation of Berry is
required in connection with the valid execution and delivery of the Agreement
by Berry, or the consummation by Berry of the transactions contemplated
thereby on the Closing thereof, except as such have been obtained or made prior
to or upon the date hereof.
  
     5.   To our best knowledge, there is no suit, action, arbitration, or
legal, administrative, or other proceeding or governmental investigation that
is material to the transactions contemplated by the Agreements pending or
threatened against or affecting Berry or any of its businesses or properties or
financial or other condition.
  
     We are members of the bar of the State of California, and except for our
opinion set forth in Paragraph 1 above, we do not purport to be experts on, or
to be qualified to express any opinion herein concerning, nor do we express any
