This Charter for Development of the Alaskan North Slope is entered between the State of Alaska, BP and ARCO on November __, 1999.

BP and ARCO historically have been major participants in the development of oil resources on the North Slope of Alaska. ARCO discovered the giant Prudhoe Bay oil field in 1968. BP participated in the discovery of Kuparuk the following year. Both were leaders in building the Trans Alaska Pipeline System. Today, they are two of the largest interest owners and operators on the North Slope.

The environment for finding, developing and producing oil and gas is challenging and complex, in Alaska and the world. The giant Prudhoe Bay and Kuparuk fields are in decline. World energy markets continue to experience price volatility, competition for capital and opportunities, and financial and technical challenges to discover, develop and produce new fields. These challenges have led to large-scale industry consolidation in recent years.

Earlier this year, BP and ARCO proposed to merge. The merger and its potential impact on Alaska have been analyzed and discussed by the Governor, his Cabinet-level review team, the Legislature and the public in private, in hearings and in the media since the announcement.

There is potential both for benefit and risk to Alaska in the merger as initially proposed. In BP and ARCO's view, Alaska would benefit from the combination's financial strength and expertise, and the increased efficiencies and synergies of the combination would help make Alaska more attractive in a global oil marketplace. But Alaska would, in the State's view, lose a measure of competition, diversity and balance in the exploration, development and production of North Slope resources, and Alaska would lose the varied contributions of a leading corporate citizen.

The State of Alaska is committed to maintaining and enhancing competition, diversity and balance in the exploration, development and production of North Slope resources, sustaining and growing both oil and gas production, and ensuring that the State's natural resources are developed in an environmentally and socially sensitive and responsible manner. The State has determined therefore that its support for the merger must be conditioned upon BP and ARCO making substantial marketplace and community commitments to Alaska.

Therefore, in order to provide for greater competition, diversity, corporate responsibility, renewal and growth in the exploration, development and production of Alaskan North Slope oil and gas, the State, BP and ARCO agree to this Charter and its terms as set forth below.

I. BP and ARCO Commitments Regarding Competition, Diversity and Growth.

A. Sale of Current Production. After the merger is completed, BP and ARCO will sell the following properties in the following manner:

1. Sale of Production. BP and ARCO will sell interests in the North Slope properties producing in aggregate share not less than 175,000 barrels of working interest oil per day to one or more purchasers. For purposes of this paragraph I.A., quantity will be measured by 1999 average daily production, except the Colville River Unit will be deemed to produce 80,000 barrels (gross) per day.

2. Sale of Interests including Kuparuk. BP and ARCO will enter into a contract of sale with a single qualified company ("Buyer A") for at least 125,000 barrels of working interest oil per day, including at least 40% of the Kuparuk River Unit total interest, and will take all reasonable available steps to enable that company to become the operator of that unit. In no event will BP or ARCO continue as operator of that unit after sale of the working interest oil. For purposes of this subparagraph 2, "qualified company" means a company which is currently a joint interest owner in the Kuparuk River Unit, or a company primarily in the energy business with assets of not less than $8 billion.

3. Sale of Interest in Alpine. BP and ARCO will enter into a contract of sale with a single qualified company ("Buyer B") for sufficient interest in the Colville River Unit that after the sale is completed that company will hold at least 40% of the total Colville River Unit interest. BP and ARCO will, in addition, take all reasonable available steps to enable that company to become the operator of that unit. In no event will BP or ARCO continue as operator of that unit after sale of the interest. For purposes of this subparagraph 3, "qualified company" means a company which is currently a joint interest owner in the Colville River Unit, or a company primarily in the energy business with assets of not less than $3 billion.

4. Sale of Share of Pipelines. BP and ARCO will enter into a contract of sale with Buyer A and Buyer B for a commensurate interest in TAPS and intermediate pipelines as provided in Paragraph H.

B. Sale of NPRA Lease Interests. BP and ARCO will sell not less than 220,000 net acres of their aggregate NPRA holdings to one or more purchasers. BP and ARCO will enter a contract of sale with either Buyer A or Buyer B for not less than 100,000 net NPRA acres, including at least 40% of the net interests in one of the sections of the NPRA designated on Exhibit A to this Charter, and will take all reasonable available steps to enable that company to become the exploration operator in that section.

C. Sale or Relinquishment of State Leases. BP and ARCO will sell or relinquish at least 400,000 net acres of undeveloped state leases, including sufficient interests in onshore/non-unitized state leases to reduce their aggregate holdings in such leases to not more than 500,000 net acres. BP and ARCO will manage the sale of this acreage to result in two exploration operatorships other than BP or ARCO in material and significant geologic play fairways on the North Slope (lease groupings which the parties agree meet this requirement are listed in Exhibit B to this Charter). BP and ARCO agree to meet and confer with representatives of the Alaska Department of Natural Resources, beginning within 10 days after the merger is completed and continuing for the period reasonably necessary to review the number, status, prospectivity and possible transfer options for all such holdings, as well as intended marketing or relinquishment plans.

D. Terms of Sales. Contracts for the full aggregate amount of the interests sold under paragraphs I.A. and I.B. will be signed within 6 months after the merger is completed and those transactions will be closed not later than 12 months after the merger is completed. Transfers under paragraph I.C. will be made within the period prescribed by law. All transfers of whole or partial interests in the properties and pipelines referenced in paragraphs I.A.-I.C. will be absolute, in good faith and with no minimum price. BP and ARCO agree that they will not reacquire interests transferred under paragraphs I.A.-I.C. by any means without advance approval of the State. Except as specifically provided in paragraphs I.A-I.C. and otherwise in this Charter, the sales contemplated in paragraphs I.A.-I.C. may be to various parties and include interests from various units and leases as determined by BP and ARCO. BP and ARCO may retain an interest in the units and leases it sells under paragraphs I.A.-I.C., subject to the requirement that any interest retained in exploration leases be subject to non-consent provisions permitting investment by other interest owners without BP or ARCO's consent. Any transfer under paragraphs I.A-I.C. will be subject to all necessary state and federal regulatory approvals and other requirements. BP and ARCO will use their best efforts to secure such approvals.

E. Data Availability. After the merger is completed, BP and ARCO will make their proprietary North Slope seismic and well data publicly available for purchase by any person where they have the legal right to do so. Where they do not currently have the legal right to do so, they will diligently and in good faith seek permission from the other joint interest owners to make the data available. Unless otherwise approved by the State, BP and ARCO will make the data available by contracting with a third party company that will market the data at prices it independently determines. BP and ARCO will ensure that the data is publicly available as soon as is reasonably practicable but in all events not longer than 3 months after the merger is completed. BP and ARCO will provide the State with (1) a list of which of their North Slope seismic and well data can be made available on their own and which requires the consent of parties other than BP or ARCO, and (2) a list or lists showing all of BP and ARCO's North Slope seismic and well data from 1958 on indicating the acquisition area, the size of the acquisition area, the ownership status (sole, joint, group shoot, trade, purchase or license), when the data was acquired, the survey type, and the operator and the contractor. For data acquired after 1984, these lists will be provided as soon as is reasonably practicable but in all events before December 31, 1999. For data acquired before 1985, these lists will be provided as soon as is reasonably practicable but in all events within 3 months after the merger is completed.

F. Facilities Access.
1. In the State's view, the Commissioner of Natural Resources possesses the statutory, regulatory and contractual authority to require working interest owners in DNR-approved units to provide others access to existing production and other lease facilities, on terms that are non-discriminatory, just and reasonable. The Commissioner may require access whenever necessary to maximize the economic and physical recovery of the State's oil or gas resources, maximize competition among parties seeking to explore and develop the resources, minimize the adverse effects of exploration, development, production and transportation activity, and otherwise to protect the best interests of the State. Binding arbitration between BP or ARCO and others under subparagraph 2 does not affect the Commissioner's authority to resolve questions of facility access.
2. BP and ARCO currently take no position on the State's view. BP and ARCO nevertheless commit that, after the merger is completed, neither BP nor ARCO will unreasonably withhold their voting support as facilities owners for allowing nearby satellites to have access to existing unit facilities on reasonable commercial terms. BP and ARCO agree that if a nearby satellite owner reasonably and diligently negotiates to unsuccessful impasse with facilities owners that include BP or ARCO, and after 90 day advance notice to BP and ARCO, BP and ARCO agree to subject themselves to binding arbitration governed by the rules of the American Arbitration Association on the question of reasonable commercial terms for that access.

G. Purchases From Minor Interest Owners. After the merger is completed, BP and ARCO agree to offer any producer of up to 5,000 barrels per day the terms reflected in the form purchase contract which is Exhibit C to this Charter. BP and ARCO may limit the total purchased under all such contracts to 25,000 barrels per day. Only barrels acquired through a production interest count against the 25,000 barrels per day limit.

H. Divestiture of TAPS and Feeder Lines.
1. In order to satisfy the State's concern that the purchasers of the production interests sold under paragraph I.A. of this Charter (the "Transferee(s)") be similarly situated to BP and ARCO by ownership in TAPS, within the time frame established for paragraph I.A. transfers, BP or ARCO will enter into a contract with each Transferee to sell a share of BP and ARCO's combined interest in TAPS sufficient to carry the production sold to that Transferee. For purposes of this paragraph I.H., production quantity will be measured in the same manner as under paragraph I.A. and TAPS capacity will be measured in accordance with the Amended and Restated Capacity Settlement Agreement in the fixed amount of 1380 mbd.
2. After all contracts contemplated in subparagraph 1 have been entered, and during the remaining term of this Charter, BP or ARCO will offer to sell additional interests in TAPS to any person requesting to purchase a share in TAPS, up to a total aggregate amount under this paragraph I.H. of 22.3547% of total TAPS ownership. The additional transfers contemplated by this subparagraph 2 will be in minimum increments of 2% of total TAPS ownership, valued at not more than the ad valorem tax value as of the time of the offer, less 5%. The parties agree that the price at which the TAPS interest is sold will not be precedent in any property tax proceeding regarding the value of TAPS.
3. Within the time frame established for paragraph I.A. transfers, BP and ARCO will enter into a contract with each Transferee to sell to that Transferee a separate share of BP and ARCO's aggregate interest in the Oliktok pipeline and in each of the intermediate crude oil common carrier pipelines serving the specific units in which the production interests to be transferred to that Transferee are located (the "relevant intermediate pipelines"). The ownership interest in each relevant intermediate pipeline to be sold to each Transferee will be equal to the percentage which the production sold under paragraph I.A. to that Transferee flowing through that pipeline bears to the overall throughput of that pipeline. The relevant production and throughput levels will be measured in the same manner as under paragraph I.A. The percentage of the Oliktok pipeline to be sold will be equal to the percentage share of the KRU sold pursuant to subparagraph I.A.2.
4. Any transfer under this paragraph I.H. will be subject to all necessary state and federal regulatory approvals and any preference rights and required approvals of the other TAPS and relevant intermediate pipeline owners. BP and ARCO will use their best efforts to secure such approvals. BP and ARCO will vote their entire interest in TAPS and the relevant intermediate pipelines in support of any such transfer. In the event any other TAPS or relevant intermediate pipeline owner exercises its preference rights with respect to the sale of a pipeline interest pursuant to subparagraphs 1, 2 or 3 hereof, the sale to that other owner will be considered a sale satisfying the obligations of that subparagraph.
I. Offer to Sell Excess Jones Act Ships. If BP's and ARCO's combined long-term ANS Jones Act fleet requirements are such that one or more ships becomes surplus of those requirements, BP or ARCO (as the case may be), will offer to sell the surplus ship or ships to other ANS producers on reasonable commercial terms. If BP or ARCO does not own the ship or ships, it will not object to arrangements by another ANS producer to acquire the ship or ships from the owner. Further, in the event that the purchaser of the ship or ships seeks ship operation services from the Alaska Tanker Company, Inc., BP will not object. Nothing in this paragraph requires BP or ARCO to assume any liability of another ANS producer concerning any of these transactions.

J. Natural Gas.

1. During the period through December 31, 2001, BP and Arco agree to commit up to 1.2 billion cubic feet per day of working interest gas to a project to commercialize Alaska North Slope gas, that meets the following criteria by such date:

a. The project has sufficient financial backing to underpin a long term 100% take or pay arrangement from the purchaser if the project requires a long term gas sales commitment from the producer(s).

b. The project has the demonstrated ability to acquire all requisite governmental and partner approvals.

c. The project commits to a project schedule which includes full ramp-up no later than 2010.

d. If the project is an LNG project, it must have a minimum netback price for the gas of P = $1.00 * (WTI/$17.50) where "P" is the Price per MMBtu applicable to the month of delivery; "WTI" is the Final Settlement price for NYMEX West Texas Intermediate Crude Oil contract for the prompt month. BP or Arco shall realize the above netback after payment of any taxes, including severance, fees or assessments imposed with respect to the gas at and after the delivery point.

e. If the project is a pipeline to the Lower 48, it will have a defined tariff structure applicable to gas transported on behalf of BP or Arco resulting in a total volumetric tariff to Chicago of $1.60/mcf transported, or less.

BP or Arco may put forward their own project to take advantage of this commitment.

If more than one project meets the criteria set forth above before December 31, 2001, then the project that offers the highest product of wellhead netback price (net of production, severance or other taxes or fees) times sales volume during the first five years of its life will receive the gas commitment.

2. To be eligible for this commitment, the project shall also be subject to the following :

a. The delivery point for gas will be the Residue gas discharge point of the Low Temperature Separators at the Prudhoe Bay Unit Central Gas Facility, or such other point as agreed by the Parties.

b. The gas will be taken at normal operating conditions at the Residue gas discharge point of the Low Temperature Separators at the Prudhoe Bay Unit Central Gas Facility, or such other point as agreed by the Parties.

c. BP or Arco will retain the right to recover the liquids contained in the gas stream delivered to any downstream delivery point(s) or extracted while in transit on any pipeline.

II. BP and ARCO's Environmental and Community Commitments.

A. North Slope Environmental Commitments. After the merger is completed, BP and ARCO will take the following steps to improve and protect the environment on the North Slope.

1. Cleanup of Abandoned Sites. BP and ARCO will take a leadership role in the assessment and environmental clean up of the North Slope "orphan sites" identified in Exhibit D1, up to a maximum expenditure under this paragraph II.A.1. of $10,000,000. In carrying out this role, BP and ARCO will consult with the Alaska Department of Environmental Conservation (ADEC) concerning site goals, standards and methods and will substantially complete the assessment and cleanup to the standards approved by ADEC under applicable law within six years after the merger is completed. In addition, BP and ARCO will work cooperatively with ADEC to develop a joint database of North Slope contaminated and solid waste "orphan sites" which includes the nature and location of the sites, the responsible parties and the relative priority for cleanup of each site based upon preliminary evaluation of the risk of harm to human health and the environment posed by the site. BP and ARCO will meet and confer with ADEC from time to time thereafter to arrange for priority re-ordering and substitutions and additions to Exhibit D1 as requested by ADEC, subject to the spending cap identified above and to the further requirements that there is no known viable responsible party for any substitute or additional site and the site has been wholly vacated.

2. Cleanup of Abandoned Empty Barrels. BP and ARCO will require contractors conducting seismic or exploration work for them to collect and deliver abandoned empty barrels to BP or ARCO operations for handling, to inventory and map locations of empty barrels and barrels containing product, and to report any visible signs of ground contamination associated with the barrels. BP and ARCO will periodically report to ADEC regarding this effort and provide ADEC with the inventory lists, maps and reports which are developed.

3. Cleanup of Existing BP and ARCO Sites. BP and ARCO will assess and clean to the standards approved by ADEC under applicable law the contaminated sites listed on Exhibit D2. BP and ARCO will work cooperatively with ADEC and the land manager to develop cleanup plans and schedules to complete required assessment and cleanup activities at these sites. Assessment and cleanup activities at sites which are currently accessible will be substantially completed by year-end 2005 for the sites listed as "high" priority sites in Exhibit D2 and by year-end 2007 for the remainder. Sites which due to operational restrictions cannot be fully cleaned until facility or equipment abandonment will be identified by BP, ARCO and ADEC for completion according to a mutually agreed schedule. Nothing in this paragraph is intended to eliminate or supercede any other obligations BP or ARCO may have to assess, cleanup or restore these or any other sites.

4. Cleanup of Inactive Reserve Pits. BP and ARCO will comply with the requirements of 18 AAC 60.440 with respect to their inactive reserve pit sites and will close the inactive reserve pits subject to the Order dated May 3, 1993 in Natural Resources Defense Council Inc. v. ARCO Alaska, Inc., No. A88-287 CIV (D. Alaska) as amended within the designated time period established by the court in that matter, and will close other ARCO and BP inactive reserve pits listed on Exhibit D.3.A. by the end of 2007 (except that in the event of currently unprojected operational delay affecting any BP site, that site may be completed on a separate mutually agreed schedule). BP and ARCO will close the ARCO and BP inactive reserve pits listed on Exhibit D.3.B. according to a mutually agreed schedule that ends a reasonable period after work on the D.3.A. sites has been completed.

5. Commitment to North Slope Spill Response. BP and ARCO will support, at their proportionate share, an independent professional North Slope spill response organization, such as Alaska Clean Seas or a substantially equivalent organization, and will encourage the fullest possible participation in this organization by all North Slope producers. BP and ARCO will support and vote in favor of funding to the North Slope oil spill response organization for an Arctic spill response research and development program (jointly agreed to by the spill response organization, BP, ARCO and ADEC) at an average annual level of not less than $200,000 during the 10 year period following completion of the merger.

6. Commitment to Corrosion Monitoring. BP and ARCO will, in consultation with ADEC, develop a performance management program for the regular review of BP's and ARCO's corrosion monitoring and related practices for non-common carrier North Slope pipelines. This program will include meet and confer working sessions between BP, ARCO and ADEC, scheduled on average twice per year, reports by BP and ARCO of their current and projected monitoring, maintenance and inspection practices to assess and to remedy potential or actual corrosion in these lines, and ongoing consultation with ADEC regarding environmental control technologies and management practices.

7. Additional Expenditure Commitment. BP and ARCO will pay or spend up to an aggregate total of $500,000 each year during the 10 year period following completion of the merger for any combination of the following as requested annually in writing by the ADEC Commissioner: additional orphan site assessment or cleanup in excess of cap established in subparagraph 1; additional Arctic spill response research and development in excess of amount established in subparagraph 5; and/or an expert or experts chosen by ADEC to provide expert advice to ADEC regarding pipeline corrosion issues.

B. Marine Environmental Commitments.

1. Renewed Commitment to OPA 90. BP and ARCO renew their commitment that neither of them will seek to be relieved of the vessel retirement or replacement requirements of the federal Oil Pollution Act of 1990 ("OPA 90"), nor will either of them lobby for a reduction in its current requirements, nor will they take any other action to extend the retirement dates of the non-double-hulled tankers in their combined fleet beyond the currently scheduled retirement dates .

2. Replacement Vessels. In furtherance of their continuing commitment to meet or exceed the OPA 90 standards and timetable, BP and ARCO will complete the purchase and delivery of the three ARCO Millennium class tankers on current order to replace single hulled tankers now used in the combined fleet, and will order and purchase additional tankers to meet their combined fleet requirements on average one year earlier than required by OPA 90, with the expected result that the combined fleets will be entirely double-hulled by mid-year 2007. These additional purchased tankers will each have safety related attributes substantially equivalent to or better than Millennium or Cape class tankers, including new build double-hulls (wholly new construction), main power plant redundancy, twin propellers, twin rudders, twin independent sets of steering gear, and proven electronics (including navigation, course tracking, collision alarms, engine room monitoring, cargo and ballast monitoring, and fire and safety systems).

3. Marine Operations. After the merger is completed, BP and ARCO will continue to encourage and support the company operating ANS tankers for them in using a performance management program for the regular review of its practices related to its management and operations including a safe environment, training and qualifications, and vessel operation, maintenance and management procedures. The parties expect this program will include meet and confer working sessions between the operating company and ADEC, scheduled on average once per year, reports at those working sessions by the operating company of their current and anticipated management and operations practices, ongoing consultation between the operating company and ADEC regarding ANS trade tanker management and operations practices, and the involvement of BP and ARCO in those sessions and consultations on a monitoring basis. In addition, BP and ARCO will encourage the operating company to allow the opportunity for ADEC to observe management and vessel audits performed as part of a certification or re-certification process for the International Maritime Organization's International Safety Management Code or for the International Standards Organization.

C. Continued Commitment to Alaska Hire.
1. Alaska Hire Program. BP and ARCO agree that, after the merger is completed, they will continue with and extend their commitment to the people of Alaska to utilize a voluntary program to employ residents of Alaska and to use Alaska businesses. It is expected by the parties that this program will include the attributes that:
a. BP and ARCO will comply with all valid federal, State and local hiring laws in hiring Alaska residents and contractors, and within the constraints of law will employ Alaska residents and contractors to the extent they are available and qualified;
b. When recruiting for new hires, BP and ARCO will advertise for available positions locally and use Alaska job service organizations to notify the Alaskan public;
c. BP and ARCO will use best efforts to contract with Alaska firms and fabricate modules in Alaska whenever feasible (in determining feasibility, BP and ARCO will consider commercial, health, safety, and environmental conditions and requirements to ensure maintenance of BP and ARCO's operational standards); and
d. BP and ARCO will, to the extent permitted by law, encourage its contractors to employ, and train when necessary, residents of Alaska.
2. Reporting. BP and ARCO agree to submit to the Director, Division of Oil and Gas, for transmission to the Department of Labor, an annual report that details the specific measures that they and their contractors and subcontractors have taken or are planning to take to recruit qualified Alaska residents for available jobs, describes on-the-job training opportunities, and describes their efforts to use Alaska businesses for work in connection with their leases and associated activities. BP and ARCO will also furnish the Department of Labor a quarterly report regarding their employment of Alaska residents. The report will include statistical data concerning the number of resident personnel hired within the previous year.
3. Construction. The program and reporting described in this paragraph are intended to be fully consistent with the 1996 amendments to paragraphs 41 (1980 leases) and 31 (1983 lease) of the Northstar Unit leases between the State and BP.
4. Alaska Native Recruitment, Training and Hire. BP and ARCO further acknowledge their continuing support for the recruiting, training and hiring of Alaska Natives and the parties' common understanding of the desirability of providing Alaska's first citizens opportunities to participate in the economic benefits of oil and gas development, most of which takes place in rural Alaska.

D. Community Charitable Commitment. Within three months after the merger is completed, BP and ARCO will establish a charitable entity dedicated to funding organizations and causes within Alaska. The entity will provide 30% of its giving to the University of Alaska Foundation and the remainder to general community needs. Funding decisions by the entity will be made by BP and ARCO, with the advice of a board of community advisors. BP and ARCO will provide ongoing funding to this entity in an amount that is equal to .2% of BP's and ARCO's combined aggregate net Alaska liquids production after royalty times the price for WTI. Specific entity funding levels will be calculated annually, on the same date each year, referencing the liquids production and the average NYMEX WTI prompt month settlement price for the 12 months immediately preceding the calculation.

III. Alaska's Commitments.

The State of Alaska finds that this Charter adequately addresses the concerns raised by the State during its merger review, that this Charter will provide for greater competition, diversity, corporate responsibility, renewal and growth in the exploration, development and production of Alaskan North Slope oil and gas and is by virtue of these significant benefits in the best interest of Alaska and its people. The State accordingly agrees that, in exchange for BP's and ARCO's fulfillment of their obligations under this Charter, it will not seek to enjoin the merger or seek additional orders or judgments under AS 45.50.580 related to a claim that the merger is unlawful under AS 45.50.568.
IV. BP Amoco, p.l.c.'s Commitments.

BP Amoco, p.l.c. acknowledges that, after the merger is completed, it will be the ultimate parent company of the BP and ARCO corporate entities owning the Alaska assets which are the subject of this Charter and which accordingly are the primary parties with the State of Alaska herein. In order to provide further assurance to the State that the commitments made in this Charter by these primary parties are fulfilled in all respects, BP Amoco, p.l.c. guarantees that (1) these BP and ARCO corporate entities, or such other BP/ARCO Group companies to which the obligations under this Charter are assigned or otherwise transferred, will remain fully capable during the term of this Charter to fulfill all commitments made by them herein and (2) if for any reason a commitment made by them in this Charter goes unfulfilled past the time performance is due, BP Amoco, p.l.c. will cause that performance to be otherwise fulfilled.

Except as otherwise provided in this Charter, nothing herein shall be construed to impose a duty or obligation on BP or ARCO to make any additional agreements with or concessions to any other governmental or regulatory body. Where an act required of BP or ARCO under this Charter is subject to regulatory approval or action, the time limits stated in this Charter will be deemed extended as may be necessary to accommodate the time involved in securing those regulatory approvals if BP and ARCO have acted with reasonable diligence in obtaining those approvals.

E. Reporting, Notice and Access to Records.

1. BP and ARCO will submit an initial compliance report at the time they execute this Charter and will submit additional compliance reports beginning thirty (30) days from the date when this Charter is entered, and every thirty (30) days thereafter until the divestitures required under Section I have been completed or a trustee is appointed. Such reports will be in writing and each such report shall include, for each person who during the preceding thirty (30) days made an offer, expressed an interest or desire to acquire, entered into negotiations to acquire, or made an inquiry about acquiring any ownership interest in all or any portion of the divestiture assets, the name, address, and telephone number of that person and a detailed description of each contact with that person during that period. BP and ARCO will maintain full records of all efforts made to divest the assets under Section I.

2. BP and ARCO will notify the State of any proposed divestiture within two (2) business days following execution of a letter of intent or agreement for sale of the assets under Section I. The notice shall set forth the details of the proposed transaction and list the name, address, and telephone number of each person not previously identified who offered or expressed an interest in or desire to acquire any ownership interest in the divestiture assets. Within ten (10) days after receipt of the notice, the State may request additional information concerning the proposed divestiture, the proposed Purchaser, and any other potential Purchaser. BP and ARCO will furnish the additional information within ten (10) days of the receipt of the request. Within twenty (20) days after receipt of the notice or within ten (10) days after receipt of the additional information, whichever is later, the State will notify BP and ARCO in writing if it objects to the proposed divestiture. If the State fails to object within the period specified, or if the State provides notice that it does not object, then the divestiture may be consummated. If the State objects, the proposed divestiture may not be accomplished unless ordered by a court of competent jurisdiction.

3.
