Potomac shall make available to Eastalco the following number of kilowatts of System Capacity: 3.1.1. 210,000 kilowatts during Load Reduction Periods of the Summer Months and Winter Months, 3.1.2. 310,000 kilowatts during Monthly Peak hours of the Spring/Fall Months, 3.1.3. 350,000 kilowatts during all other hours. 3.2. PRICE OF SYSTEM CAPACITY. 3.2.1. CAPACITY CHARGE. 3.2.1.1. The Capacity Charge effective July 1, 1993 shall be $10.24 per kilowatt per month. The Capacity Charge consists of a base rate. Any change in the base rate or any additional charges or surcharges determined by the Maryland Public Service Commission to be applicable to Eastalco after December 31, 1987 and not included in Sub-Paragraph 4.2.3. hereof shall be reflected by Potomac in this Capacity Charge, and shall be subject to the provisions of Sub-Paragraph 14.3.1. The Capacity Charge shall be applied to all kilowatts of System Demand. 3.2.l.2. An Additional Capacity Charge of $2.00 per kilowatt shall be added to the Capacity Charge and this sum shall be applied to Additional Capacity in excess of System Demand. Additional Capacity shall mean all Billing Capacity kilowatts determined to be in excess of System Demand as the result of the application of Sub-Paragraphs 3.2.2.1.2 through 3.2.2.1.5. or Sub-Paragraphs 3.2.2.2.2. through 3.2.2.2.6. below, except that no Additional Capacity Charge shall be payable for kilowatts in excess of System Demand if that Additional Capacity results from the application of Sub-Paragraphs 3.2.2.1.5. or 3.2.2.2.6. when triggered by Sub-Paragraphs 3.2.2.1.1. or 3.2.2.2.1. Also the Additional Capacity Charge shall not apply in any Billing Period during which no electrolysis occurs and no molten metal is produced in Eastalco's potlines. 3.2.2. BILLING CAPACITY. Billing Capacity shall be equal to the result of the following: 2 8 3.2.2.1. For the Summer Months and Winter Months, Billing Capacity shall be the greatest of: 3.2.2.1.1. The System Demand; or, 3.2.2.1.2. .45 times (the sum of System Energy and Off-System Energy divided by the number of hours in the Billing Period); or, 3.2.2.1.3. .30 times the Maximum Instantaneous Demand; or, 3.2.2.1.4. 130,000 kilowatts; or, 3.2.2.1.5. The highest result established by the application of Sub-Paragraphs 3.2.2.1.1. through 3.2.2.1.4. above during (i) the three preceding Summer Months if the computation of Billing Capacity is being made for a Summer-Month; or, (ii) the three preceding Winter Months if the computation of Billing Capacity is being made for a Winter Month. 3.2.2.2. For the Spring/Fall Months, Billing Capacity shall be the greatest of: 3.2.2.2.1. The System Demand; or, 3.2.2.2.2. .80 times (the sum of System Energy and Off-System Energy divided by the number of hours in the Billing Period); or, 3.2.2.2.3. .40 times the Maximum Instantaneous Demand; or, 3.2.2.2.4. (System Energy plus Off-System Energy divided by the number of hours in the Billing Period) less 40,000 kilowatts; or, 3.2.2.2.5. 200,000 kilowatts; or, 3.2.2.2.6. The highest result established by the application of Sub-Paragraphs 3.2.2.2.1. through 3.2.2.2.5. above during the three preceding Spring/Fall Months. 3.3. REACTIVE KILOVOLT-AMPERE CHARGE. The Reactive Kilovolt-Ampere Charge shall be the price payable for reactive kilovolt-amperes and shall be equal to the result of the following formula: $0.15 x (Reactive Kilovolt-Ampere Capacity - 25% of Billing Capacity) 3 9 3.4. UNDERMODULATION CHARGE. 3.4.1. DETERMINATION OF UNDERMODULATION CHARGE. If Eastalco fails to modulate its load under Sub-Paragraph 8.3 by at least an average of 65,000 kilowatts at the time of Potomac's Monthly Peak during the Spring/Fall Months, it shall pay an Undermodulation Charge of $5.00 per kilowatt for each kilowatt by which the total number of kilowatts of such modulation by Eastalco in the Spring/Fall Months of each calendar year is less than the product of 65,000 times the number of Spring/Fall Months in the calendar year for which the calculation is made. The Undermodulation Charge shall not apply to the Summer Months and Winter Months. 3.4.2. DETERMINATION OF LOAD MODULATION. The amount of Load Modulation for a Spring/Fall Month shall be equal to the difference between: (i) the sum of Eastalco's System Demand and any Off-System Capacity purchased during the hour of the System Demand for such month; and (ii) the sum of System Energy and Off-System Energy for such month divided by the number of hours in the Billing Period; provided, however, that for purposes of this Sub-Paragraph 3.4, (a) if System Demand during a Spring/Fall Month is 200,000 kilowatts or less, the amount of Load Modulation shall not be less than 65,000 kilowatts; and, (b) the amount of Load Modulation in any Spring/Fall Month shall not be less than 40,000 kilowatts. 3.4.3. BILLING OF UNDERMODULATION CHARGE. The billing of the Undermodulation Charge shall be determined annually and shall be billed on the December Billing Period invoice for each calendar year during the term hereof, or on the final invoice upon termination of this Agreement. 4. SALE AND PRICE OF ENERGY. 4.1. SALE OF CONTRACT ENERGY. The Eastalco facility requires an average of 310,000 kilowatt-hours per hour in order to operate at full production. Potomac shall make available System Energy and, in accordance with Sub-Paragraph 10.1, shall use its best efforts to make available sufficient Off-System Energy so that the combined availability of System Energy plus Off-System Energy averages 310,000 kilowatt-hours per hour, which shall be the Contract Energy. 4.2. SYSTEM ENERGY. 4.2.1. DEFINITION OF SYSTEM ENERGY. For purposes of this Agreement, System Energy shall mean the kilowatt-hours recorded during the Billing Period 4 10 on the Meters as delivered to Eastalco, less any Off-System Energy purchased during the Billing Period. System Energy shall be comprised of Base Energy and Incremental Energy defined as follows: 4.2.1.1. Base Energy shall be the lesser of: 4.2.1.1.1. The System Energy; or, 4.2.1.1.2. The product of the Billing Capacity and the number of hours in the Billing Period. 4.2.1.2. Incremental Energy shall be the amount of System Energy in excess of the Base Energy, if any. 4.2.2. PRICE OF SYSTEM ENERGY. The price payable for System Energy shall be the sum of: 4.2.2.1. The Base Energy multiplied by the Base Energy Charge which shall mean the rate payable pursuant to Potomac's fuel rate (or any cost recovery method which may take its place) then in effect as approved by the Maryland Public Service Commission, and adjusted for applicable siting charges; plus, 4.2.2.2. The Incremental Energy multiplied by the Incremental Energy Charge which shall mean the greater of: (i) the hourly incremental Actual Cost of energy to Potomac, before sales to non-affiliated utilities, incurred during the hours of Incremental Energy use during the Billing Period, plus l mill per kilowatt-hour, adjusted for Maryland gross receipts tax and applicable siting charges, or, (ii) the Base Energy Charge; plus, 4.2.3. OTHER ENERGY RATE COMPONENTS. If the Maryland Public Service Commission adopts a rate charge or adjustment which did not exist on December 31, 1987 that is to be collected on a per kilowatt-hour basis from Potomac's customers, such charge may be applied to the Base Energy and the Incremental Energy subject to such limits on its applicability as are adopted by such Commission, except that such charges which are directly related to the cost of fuel for Potomac may be applied to the Base Energy only. Examples for purposes of illustration only are the Maryland Energy Facility Siting Tax, which could be applied to both the Base and Incremental Energy, and the Deferred Fuel Accounting Surcharge, which could be applied only to the Base Energy. 5 11 4.3. PRICE OF OFF-SYSTEM ENERGY. The price payable for Off-System Energy shall be as set forth in Sub-Paragraph 10.2. 4.4. PROFIT SHARING SURCHARGE. The Profit Sharing Surcharge shall be the product of the Profit Sharing Rate and the System Energy. 4.4.1. PROFIT SHARING RATE. The Profit Sharing Rate shall be equal to the following: 4.4.1.1. If the Aluminum Price is less than or equal to the Lower Trigger Price, the Profit Sharing Rate shall be zero. 4.4.1.2. If the Aluminum Price is greater than the Lower Trigger Price and less than the Upper Trigger Price, the Profit Sharing Rate shall be the product of the Maximum Profit Sharing Rate, calculated to five decimal places, and the ratio R, where R equals (Aluminum Price - Lower Tricker Price --------------------------------------- (Upper Trigger Price - Lower Trigger Price) 4.4.1.3. If the Aluminum Price is equal to or greater than the Upper Trigger Price, the Profit Sharing Rate shall be the Maximum Profit Sharing Rate. 4.4.2. The Maximum Profit Sharing Rate initially shall be $0.004 per kilowatt-hour until March 1, 2000. After February 29, 2000 the Maximum Profit Sharing Rate shall be reviewed in a good faith negotiation. The adjustment in the Maximum Profit Sharing Rate would reflect the change in price levels for the types of production plant related to compliance with Phase II of the CAAA and the relative amount of investment in production plant for compliance with Phase II as compared to Phase I of the CAAA. The relative amount of investment would be computed as the ratio of the investment in production plant for compliance with Phase II of the CAAA to the investment in production plant for compliance with Phase I of the CAAA, with both investments adjusted to dollars of the same year using appropriate inflation indices. As an example, if the change in price levels was twenty percent (20%) and the investment for compliance with Phase II was one half the investment for compliance with Phase I, after adjustment for inflation, then the Maximum Profit Sharing Rate would increase by approximately ten percent (10%). 4.4.3. The Lower Trigger Price initially shall be seventy cents (70.0 (cent)) per pound of aluminum. On March 1, 1995 and each March 1 thereafter, the Lower Trigger Price shall be re- 6 12 established to the nearest tenth of a cent as the result of the following formula: Lower Trigger Price = 70.0(cent) x 1/2 x (Price Ratio + Escalation Ratio) where 4.4.3.1. The Price Ratio is the ratio: Annual Aluminum Price for the most recent calendar year) -------------------------------------------------------- (Annual Aluminum Price for calendar year 1993) 4.4.3.2. The Escalation Ratio is the ratio: (Price Deflator Index for the fourth quarter of the most recent calendar Year) -------------------------------------------------------- (Price Deflator Index for the fourth quarter of 1993) 4.4.4. The Upper Trigger Price initially shall be one hundred twenty cents (120.0(cent)) per pound of aluminum. On March 1, 1995 and each March 1 thereafter, the Upper Trigger Price shall be re-established to the nearest tenth of a cent as the result of the following formula: Upper Trigger Price = 120.0(cent) x 1/2 x (Price Ratio + Escalation Ratio) 5. MINIMUM LOAD CHARGE. In addition to the amounts payable under Paragraphs 3 and 4, if the sum of the System Energy and Off-System Energy used in a Billing Period is less than the Minimum Load, Eastalco shall pay a Minimum Load Charge for System Power, which shall be equal to 5.1. the lesser of: 5.1.1. 21,900,000 kilowatt-hours, or, 5.1.2. the difference between: 5.1.2.1. the Minimum Load, less, 5.1.2.2. the sum of the System Energy and Off-System Energy purchased by Eastalco, 5.2. multiplied by the quotient of (i) the sum of the amount payable for Base Energy in accordance with Sub-Paragraph 4.2.2.1. and the amount payable for Incremental Energy in accordance with Sub-Paragraph 4.2.2.2. divided by (ii) the number of kilowatt-hours of System Energy. 7 13 5.3. Paragraph 5 shall not apply in any Billing Period during which no electrolysis occurs and no molten metal is produced in Eastalco's potlines. 6. SALE OF IDLE CAPACITY. When Eastalco's Maximum Demand is expected to be below 240,000 kilowatts, Eastalco may give notice to Potomac that for a specified period, Eastalco will not use all or a portion of the System Capacity below 240,000 kilowatts. The period specified shall be at least one week and the amount of System Capacity specified shall be at least 10,000 kilowatts. Potomac will use its best efforts to sell such System Capacity for the period specified in the notice; provided, that such sale would not interfere with potential sales of capacity by Potomac or Allegheny that could have been made if Eastalco was using suchSystem Capacity. Eastalco will receive a credit not to exceed $500,000 per calendar month for the proceeds of any sale by Potomac equal to the lesser of: 6.1. 90% of the Capacity Revenues from such sale; or, 6.2. In the Winter Months and Summer Months, an amount equal to the sum of: (i) 130,000 kilowatts less the Maximum Demand (if that difference is greater than zero) times the Capacity Charge, and (ii) the Minimum Load Charge; or, 6.3. In the Spring/Fall Months, an amount equal to the sum of: (i) 200,000 kilowatts less the Maximum Demand (if that difference is greater than zero) times the Capacity Charge, and (ii) the Minimum Load Charge. 7. LOAD REDUCTION PERIOD. 7.1. DEFINITION OF LOAD REDUCTION PERIOD. Potomac may designate as a Load Reduction Period between one and eighteen hours during any day of the Summer Months or Winter Months that Potomac reasonably believes will be the day that Potomac's monthly maximum demand will occur; provided that the total number of Load Reduction Period hours shall not exceed (i) 850 hours during the twelve month period commencing October 1, 1990 and ending September 30, 1991 or any 12 month period thereafter, during the term of this Agreement, which commences on October 1 of a calendar year and ends on September 30 of the succeeding calendar year, or (ii) upon notice of the termination of this Agreement, the sum of 170 hours times the number of Winter Months and 85 hours times the number of Summer Months from the September 30 immediately preceding termination to the date of termination. 8 14 7.2. NOTICE TO REDUCE LOAD. Preliminary notice of a Load Reduction Period shall be given by Potomac to Eastalco no later than 4:00 P.M. of the day preceding the Load Reduction Period. A confirmation of the occurrence of a Load Reduction Period will be given no later than 6:00 A.M. of the day of a Load Reduction Period occurring during the Winter Months and 8:00 A.M. of the day of a Load Reduction Period occurring in the Summer Months. Notwithstanding the foregoing, and subject to the limitations set forth in SubParagraph 7.1., Potomac may extend an existing Load Reduction Period or designate a new Load Reduction Period after 6:00 A.M. in the Winter Months or after 8:00 A.M. in the Summer Months upon as much notice to Eastalco as is reasonably practicable. The parties may agree mutually in writing to a change in the time by which a confirmation of the occurrence of a Load Reduction Period must be given. 7.3. OBLIGATION TO MINIMIZE AND CANCEL LOAD REDUCTION PERIOD. Potomac will use its best efforts to limit the duration and frequency of any Load Reduction Period hours while not unreasonably increasing the risk that Potomac's monthly maximum demand will occur outside a Load Reduction Period. If subsequent to the designation of a Load Reduction Period: (i) Potomac's load does not materialize for the Load Reduction Period day so that Potomac no longer reasonably believes that one or more hours of the Load Reduction Period will be the hour(s) in which Potomac's monthly maximum demand will occur; and, (ii) there are no abnormal operating conditions on Potomac's system which require retention of such hours in the Load Reduction Period, Potomac shall remove as many hours as possible from the Load Reduction Period and give Eastalco prompt notice thereof; provided, however, that Eastalco may elect to retain such hours in the Load Reduction Period if it already has incurred any costs for such hours in connection with Off-System Power that would not be avoided or refunded if such hours are not retained in the Load Reduction Period. 8. POTENTIAL PEAK HOURS. 8.1. DEFINITION OF POTENTIAL PEAK HOURS. Potomac may designate as Potential Peak Hours either one or two periods of between one and eight consecutive hours during any day of the term hereof that Potomac reasonably believes will be the day that Potomac's monthly maximum demand 9 15 will occur; provided that (i) the total number of Potential Peak Hours shall not exceed 8 in any calendar day, (ii) no Potential Peak Hours may be designated on Sunday, and (iii) during the Summer Months and Winter Months, Potential Peak Hours shall be designated only within Load Reduction Periods. 8.2. NOTICE OF POTENTIAL PEAK HOURS. Preliminary notice of Potential Peak Hours shall be given by Potomac no later than 4:00 P.M. of the day preceding the Potential Peak Hours. Notice of Potential Peak Hours and a confirmation of the occurrence of the Potential Peak Hours shall be given no later than 6:00 A.M. of the day the Potential Peak Hours are to occur in the Winter Months and no later than 8:00 A.M. of the day the Potential Peak Hours are to occur during all other months.

DESIGNATION OF FIRM LOAD EMERGENCY. Potomac may designate a Firm Load Emergency at any time during the term of this Agreement that Eastalco is not purchasing Off-System Power. 9.2.3. OBLIGATION TO LIMIT OR CANCEL FIRM LOAD EMERGENCIES. Potomac will use its best efforts to limit the duration and frequency of any Firm Load Emergencies. If subsequent to the designation of a Firm Load Emergency, Potomac's operating conditions change so that continuance of the Firm Load Emergency no longer is reasonably required, Potomac shall give Eastalco prompt notice of ability to resume purchasing System Capacity and System Energy; provided, however, that Eastalco may elect to continue purchasing Off-System Capacity and Off-System Energy if, for this occurrence, it already has incurred any costs in connection with such purchases not yet delivered, which would not be avoided or refunded if Eastalco elects to resume purchasing System Capacity and System Energy. 9.2.4. NOTICE TO REDUCE PURCHASES OF SYSTEM CAPACITY AND SYSTEM ENERGY. Notice of a Firm Load Emergency shall be given by Potomac no later than 30 minutes prior to the commencement of the Firm Load Emergency. 10. OPERATIONS DURING LOAD REDUCTION PERIODS AND FIRM LOAD EMERGENCIES. Eastalco shall use its best efforts to reduce its load to a level of not more than 200,000 kilowatt-hours per hour and maintain its load at such level for the duration of any Load Reduction Period or Firm Load Emergency. Such best efforts obligation shall not obligate Eastalco, in its opinion, to jeopardize the stability of its plant operations. 10.1. OBLIGATION OF POTOMAC. During a Load Reduction Period or a Firm Load Emergency, Potomac shall purchase and deliver to Eastalco Off-System Power in accordance with the following provisions, if requested to do so by Eastalco and if Off-System Power is available, and can be delivered, from other sources not then committed to serve Potomac's load or pass-through obligations. Potomac agrees to use its best efforts to furnish Eastalco the amount of Off-System Power requested by Eastalco to replace up to 100,000 kilowatt-hours per hour of the difference between 12 18 Eastalco's average load of the previous week and 200,000 kilowatt-hours per hour. 10.2. PRICING. Potomac agrees to furnish Eastalco with the least cost Off-System Power available. The price payable by Eastalco for Off-System Power during Load Reduction Periods shall be the Actual Cost to Potomac plus 2 mills per kilowatt-hour. The price payable by Eastalco for Off-System Power during a Firm Load Emergency shall be Potomac's Actual Cost. The price in either event shall include gross receipts tax, if applicable. Potomac shall furnish Eastalco with an estimate of such price at the same time it gives notice of a Load Reduction Period under Sub-Paragraph 7.2 or a Firm Load Emergency under Sub-Paragraph 9.2.4. 10.3. INSUFFICIENT POWER. If the amount of Off-System Power delivered to Eastalco during a Firm Load Emergency in accordance with SubParagraph 9.2. is less than the amount requested by Eastalco under Sub-Paragraph 10.1., and Eastalco reduced its load at least to the level requested by Potomac, then a Recovery Period shall be established for the lesser of (i) 20 hours, or (ii) 20 hours times the quotient of the difference between the kilowatt-hours of Off-System Power requested by Eastalco and the kilowatt-hours of Off-System Power delivered to Eastalco, divided by 200,000 kilowatt-hours. In order to provide Eastalco an opportunity to attempt to restore the stability of its operations after an emergency, Potomac shall not declare any hour in a Recovery Period to be a Potential Peak Hour nor shall it declare another emergency under Sub-Paragraph 9.1.2. or 9.2; however, Potomac may declare Load Reduction Periods that include hours in a Recovery Period.

No. 53 Third Revision of Original Page No. 5E Canceling Second Revision of Original Page No. 5E ================================================================================ ENERGY CONSERVATION SURCHARGE APPLIES TO DESIGNATED RATE SCHEDULES Effective with bills rendered on and after July 7, 1994, there shall be a surcharge as set forth below to recover the cost associated with Company-sponsored programs which promote conservation and efficient use of energy and such other programs as recommended by The Collaborative and approved by the Commission. The Energy Conservation Surcharge (ECS) is applied to designated Rate Schedules to recover eligible costs applicable to that Rate Schedule. These charges will be applied each month until changed by the Commission. Applicable bills rendered shall include an amount equal to either the ECS Residential rate times the number of kilowatthours used in the billing period, or the ECS Commercial and Industrial revenue percentage rate times the total revenue exclusive of taxes, whichever is specified. The resulting charge is in addition to any minimum charge set out in the Rate Schedule and is added to the Customer's energy charge or bill before any tax surcharge is levied against the Customer's total bill. Amounts billed hereunder shall be subject to late pay charges. CALCULATION OF SURCHARGE The Surcharge is calculated for the 12-month period beginning January 1. For the Residential class, the Surcharge is $0.00029 per kilowatthour and is calculated by dividing the eligible costs expected to be allocated to that Customer class for the period by the kilowatthour sales expected for that schedule over the same period. For the Commercial and Industrial class, the Surcharge is 3.48% of total revenue exclusive of taxes and is calculated by dividing the eligible costs expected to be allocated to that Customer class for the period by the total expected annual revenue from that Customer class. The calculation includes an adjustment for gross receipts tax. Eligible costs will be based on program descriptions filed with the Commission by November 1 of the previous year, which will be consistent with the Long Range Plan filed previously during the same year. An estimated Surcharge will be filed with the Commission on February 1. The formal ECS will be filed March 1 to become effective April 1 for the next twelve months. Upon determination that an ECS, if left unchanged, would result in a material over/undercolection, the Company may file a proposed interim revision of the ECS for Commission approval. ================================================================================ ISSUED BY ALAN J.

No. 53 Second Revision of Original Page No. 5E-2 Canceling First Revision of Original Page No. 5E-2 ================================================================================ ELIGIBLE COSTS Costs eligible for recovery through the ECS are approved by the Commission and include: Program Costs -- Program Costs are the estimated costs for research, development, implementation and operation of experimental and pilot programs and of programs approved by the Commission to be incurred by the Company during the 12 month period commencing each January 1, net of program amounts presently included in base rates. Program costs include, but are not limited to Company labor, rebates, payments to third parties for program implementation direct marketing costs incurred by the Company, market research costs, experimental and pilot program development, consultant fees, applicable software licenses, program measurement and monitoring hardware, and all other administrative activities associated with program development and implementation such as advertising, program management, research and development activities, experimental and pilot program development, and monitoring and evaluation. All program costs for Residential Class programs will be deferred and amortized (straight line) over five years. All program costs associated with Commercial and Industrial Class programs will be deferred and amortized (straight line) over seven years. Beginning in 1995 the ECS for residential programs will be calculated on a basis which amortizes program costs over seven years. Unamortized balances will accrue interest monthly at the rate of return (adjusted for taxes) allowed in the Company's last Maryland rate proceeding. Lost Revenues -- Lost revenues are base rate revenues, including surcharges that do not have a true-up provision, not billed because of lost sales from approved conservation programs. They are determined prospectively for the 12 month period commencing each January 1. The estimates of lost revenue are prepared on a program basis by Rate Schedule. Lost revenues are calculated as decremental demand and energy per participant or measure installed times appropriate base rate demand and energy charges, net of gross receipts tax. The estimates are based on "best available" demand and energy savings data and the latest available measurement and evaluation information. Lost revenues are calculated monthly and deferred with interest until recovered in revenue, unless the earnings test is not satisfied. Reconciliation of lost revenues is based upon actual program participation or number of measures installed. There is no retroactive adjustment for changes in the per unit demand and energy savings estimates. Lost revenues accrue between base rate cases except when the earnings test is not satisfied. ================================================================================ ISSUED BY ALAN J.

No. 53 First Revision of Original Page No. 5E-3 Canceling Original Page No. 5E-3 ================================================================================ ELIGIBLE COSTS (Continued) Performance-Based Shared Savings Incentive -- The Company can earn an incentive if it attains specified goals. Goals are established as a part of each program approved by the Commission. Achievement will be based on the aggregate energy saved by all active, approved programs. The energy saved per measure or participant will not be adjusted retroactively. The number of measures, units, or participants will be the actual number attained. The amount of the incentive will be based on a share of the net savings from each program as calculated using the Total Resource Cost Test (TRC) filed by the Company and approved by the Commission. The aggregate goals and the Company's shared savings amounts are: % Goal Achieved % TRC --------------- ----- Less than 80% 0% 80% - 99% 6% 100% - 119% 7.5% 120% & Over 10% The highest percent incentive determined above applies uniformly to the aggregate total of all net savings of all of the programs used in establishing the goal. The incentive will be grossed-up for all relevant taxes. Recovery of any incentive awarded through the ECS will be based on the actual amount earned in the previous year. Reconciliation Factor -- The reconciliation factor corrects for over/undercollection of program costs, lost revenues, interest, and incentives. The differences between the prospective estimates of program costs, lost revenues, incentives, and interest included in the current year ECS and the actual costs determined at the end of the year are included in the ECS reconciliation factor. The reconciliation factor is debited or credited against the costs eligible for recovery through the ECS during the next year. Interest is included in the reconciliation factor on the over/undercollection at the rate of return, adjusted for taxes, allowed in the Company's last Maryland rate proceeding. Interest shall apply to the over/undercollection as recorded in the deferred accounts and will be compounded semi-annually. The factor is adjusted for gross receipts taxes. ================================================================================ ISSUED BY ALAN J.

S. C. Md. No. 53 First Revision of Original Page No. 5E-4 Canceling Original Page No. 5E-4 ================================================================================ COST ALLOCATION Eligible costs will be allocated to the Rate Schedules participating in specific programs as follows: Program Costs: (a) Direct program costs will be assigned to specified approved programs. (b) Common costs will be allocated to each approved program in proportion to assigned program costs. (c) If a single program involved more than one Rate Schedule Grouping, the total assigned program costs will be allocated to the Rate Schedules participating in the programs by ratio of the number of participants or measures in the individual schedules. Cost Based Shared Savings Incentive -- Earned incentive costs are allocated to the Rate Schedules and Rate Schedule Groupings participating in proportion to the allocation of total assigned program costs for the year in which the incentive was earned. Lost Revenues and Reconciliation Factor -- Any such eligible costs or credits are directly assigned to the schedule of origin. EARNINGS TEST The ECS is subject to an earnings test. The test is performed by the Company on the first day of the month using the Company's most recent quarterly financial results on file with the Commission. The earnings test is passed when the Company's actual rate of return, on a Commission-adjusted basis, including adjustments for the ECS costs, is equal to or below the rate of return allowed in the Company's last Maryland rate proceeding. The earnings test is failed when the actual rate of return exceeds the return allowed in the Company's last Maryland rate proceeding. During periods in which the Company fails the earnings test (1) the Commission approved ECS, as revised each April 1, will continue unadjusted, and (2) incentives previously earned and approved by the Commission, as well as program costs, will be unaffected by the earnings test, and (3) no further lost revenues will be deferred. The portion of the ECS related to lost revenues recovery will be applied to reduce the balance of the deferred costs during such periods. Deferred costs earn interest compounded semi-annually at the rate of return (adjusted for taxes) allowed in the Company's last Maryland rate proceeding. ================================================================================ ISSUED BY ALAN J.

NOIA, PRESIDENT Issued December 28, 1993 To become effective on all service rendered on or after January 5, 1994 through January 4, 1996 Approved at Public Service Commission's Administrative Meeting of December 22, 1993 49 STIPULATION REGARDING THE ESTABLISHMENT OF RATES UNDER THE POWER CONTRACT BETWEEN POTOMAC EDISON AND EASTALCO PARTIES The parties to this stipulation are: The Potomac Edison Company Eastalco Aluminum Company Maryland People's Counsel Staff of the Maryland Public Service Commission Westvaco Corporation TERM OF THIS STIPULATION This stipulation shall be effective upon the approval by the Public Service Commission of Maryland of the new power contract between The Potomac Edison Company and Eastalco, which is attached hereto. This stipulation shall remain effective until the earlier of (i) the date that the contract terminates or (ii) the effective date of a further amendment to that contract that is inconsistent with this stipulation. COST OF SERVICE ALLOCATION As part of any application for a change in base rates, Potomac Edison shall prepare and present a 6 CP - Defined Months cost of service allocation study which allocates costs between Eastalco and all other customer classes based on the six coincident peaks of each customer class in the months defined as Winter Months and Summer Months in the power contract between Potomac Edison and Eastalco. Such cost allocation study shall be substantially the same as the cost allocation study included as Part 2 of Exhibit FDS-2 in the Direct Testimony and Exhibits of Francis D. Stillman, Potomac Edison Exhibit No. 5 in Case Number 8469, except that the 12 CP cost allocator labelled D1, Demand at Generation Level (ACP), shall be replaced by the 6 CP - Defined Months allocator. In particular, all cost of service allocations related to production and transmission plant will use the 6 CP - Defined Months allocator. This includes the investment in CAA related capital plant for compliance with Phase I and Phase II OF THE CAAA. 1 50 STIPULATION (Continued) - June 15, 1993 RATES TO EASTALCO Subject only to the Rate Shock Provision, the base rates to Eastalco shall be established to produce an indexed rate of return of not less than 0.995 nor more than 1.005 based on the 6 CP-Defined Months cost of service allocation normalized as discussed below. RATE SHOCK PROVISION In order to avoid rate shock to any customer class, in each base rate proceeding the base rates to Eastalco shall be established to produce an indexed rate of return as close as possible to 1.0 based on the 6 CP - Defined Month allocation subject to the following: If Potomac Edison receives a base rate increase, the percentage increase in base rates to Eastalco shall not be less than twenty-five percent (25%) nor more than one hundred seventy-five percent (175%) of the percentage increase in jurisdictional base revenues. If Potomac Edison receives a base rate decrease, the percentage decrease in base rates to Eastalco shall not be less than twenty-five percent (25%) nor more than one hundred seventy-five percent (175%) of the percentage decrease in jurisdictional base revenues. NORMALIZATION PROVISION Potomac Edison shall make a normalization adjustment to remove any Profit Sharing Surcharge revenue from the 6 CP - Defined Month cost of service study. If Potomac Edison believes that reductions in Eastalco System Demands were less than normal during the test year, or that there were increases in revenues from Eastalco that were caused by Eastalco's failure to reduce System Demand to a normal level, then Potomac shall use its best efforts to make adjustments to normalize the 6 CP - Defined Month cost of service study. A normalization adjustment for the winter/summer time period may only occur if Eastalco's System Demand is greater than 10 MW from the average of the winter/summer months of the cost of service study year and the previous year. A normalization adjustment to eliminate ratchet revenues for the spring/fall time period may only occur if Eastalco's System Demand is greater than the billing capacity 2 51 STIPULATION (Continued) - June 15, 1993 calculated according to the Eastalco Contract, Subparagraph 3.2.2.2.4. The adjustment could reduce Eastalco's revenues to the level which would have occurred if the billing capacity calculated in Subparagraph 3.2.2.2.4 had been used in the monthly bill calculation. Such normalization adjustments may include but are not limited to: (i) revenue from the operation of the ratchet provisions in the Eastalco Contract (Subparagraphs 3.2.2.1.5 and 3.2.2.2.6) may be removed from the 6 CP - Defined Month allocation study; (ii) billing demands shall be recomputed as if normal reductions in Eastalco's System Demands had occurred in the study period and revenue reduced accordingly; and (iii) the 6 CP allocation factor shall be determined based on normal reductions in Eastalco's System Demands. RATES TO OTHER CUSTOMERS Except as set forth below under "allocation of profit sharing revenues" the allocation of the remaining revenues, costs and rate base to customer classes other than Eastalco and the design of rates to recover such costs from all customer classes other than Eastalco shall not be affected by this stipulation. The cost allocation will be a two-step process. The 6 CP-Defined Month cost of service study used to establish rates to Eastalco will be the first step. The second step will be a cost of service study for all other customers. All costs, revenues and rate base related to Eastalco as determined in the 6 CP- Defined Months cost of service study, will be removed from the second cost of service study. NO PRECEDENTS This stipulation represents a compromise among the parties in recognition of Eastalco's separate class status, its unique contract, manner of usage of electrical energy, and usage of electricity as a production process raw material. Agreement to the terms of this stipulation does not mean that any party supports the application of rate allocations and principles in this stipulation outside of the specific context of this stipulation. No party shall cite this agreement in any tribunal for any purpose outside of this stipulation. This stipulation is not evidence of acceptance or rejection of any rate allocation or rate design principle by any party. Moreover, the parties agree that this agreement shall be of no precendential value and is in no way 3 52 STIPULATION (Continued) - June 15, 1993 intended to influence Commission decisions regarding proper cost allocation or rate design except as specifically agreed herein. ALLOCATION OF PROFIT SHARING REVENUES Under conditions set forth in the new Subparagraph 4.4 of the Eastalco power contract, Eastalco will pay a profit sharing surcharge to Potomac Edison. The revenue from the profit sharing surcharge shall be distributed by Potomac Edison to all its Maryland jurisdiction customer classes other than Eastalco. The timing of distributions and the allocation of profit sharing revenues among customer classes other than Eastalco shall be done in accordance with Exhibit A, "Procedures for Refund of Eastalco 'Profit Sharing' Revenues to Potomac Edison's Other Maryland Jurisdictional customers," which is attached hereto and made a part of this stipulation. ADJUSTMENT OF PROFIT SEARING The formulas set forth in the Electric Service Agreement between Eastalco and Potomac Edison for the Lower Trigger Price and the Upper Trigger Price have been developed based on the best information and projections of inflation and aluminum prices currently available. The intent of these formulas is that during periods of strong aluminum markets there should be some revenues from the Profit Sharing Surcharge. Potomac and Eastalco shall review these formulas prior to June 1, 1996, and each three years thereafter, to determine whether they are working as intended and report to the Commission their determination. If, after review of the report, any party determines that the formulas are operating in such a manner that the amount of revenue from the Profit Sharing Surcharge is higher than intended or lower than intended, taking into account the conditions of the aluminum market, the parties agree to negotiate in good faith modifications to the formulas or this stipulation. The intent of such negotiations would be to reestablish the benefits to all parties intended to be achieved by this stipulation. OTHER MATTERS The parties acknowledge that Eastalco's load and its load modulation activities have a significant effect on Maryland demand and generation resources required. 4 53 STIPULATION (Continued) - June 15, 1993 They further acknowledge that notifications required from Eastalco to the Company as regards contract extension or termination are an important factor in effective least cost planning for its Maryland customers. The parties also acknowledge that Eastalco's load for planning purposes is about 140 MW of Potomac Edison's total estimated demand in the year 2000 and that Eastalco's presence or absence beyond the initial contract term thus creates a significant planning uncertainty. The parties will not challenge the prudence of any plant that, at the time construction began, was prudent to build, even though, after construction started, or was completed, the plant served to provide excess capacity due solely to the absence of Eastalco as a 140 MW customer. This does not limit the rights of any party to challenge whether the plant construction was accomplished in a prudent manner or whether the Company proceeded with the start or continuation of construction at a time when the Company had actual knowledge that Eastalco would no longer continue as a 140 MW customer and actual knowledge that such additional plant was not needed for service to other customers. This agreement also does not restrict or diminish the parties' rights to raise any issues regarding whether any portion of the Company's rates are "just and reasonable." 5 54 STIPULATION (Continued) - June 15, 1993 REQUEST FOR APPROVAL The parties jointly request that the Commission approve the amendment to the contract between Potomac Edison and Eastalco and this stipulation.

A) The deferred account will be examined each November to include any profit sharing revenues resulting from Eastalco's billings through October. The Rate Adjustment Credit for the following year will commence with customer bills for the first billing cycle in January. B) If the balance in the deferred account equals or exceeds $1,000,000, a credit will be determined for the next calendar year. This credit, in cents/kWh or $/kWh, will be applied to customer bills for the ensuing 12-month calendar period as a Rate Adjustment Credit (RAC). C) If the balance is less than $1,000,000, no credit will be calculated. The balance will carry over into the following year and continue to earn interest as described above until the next review. If, however, the balance is less than $1,000,000 and an existing "RAC" is in effect, the existing "RAC" will continue until the month prior to when the account would reach a zero balance. D) The balance to be returned to other customers will be allocated among the rate schedules in accordance with the demand allocation method approved in Potomac Edison's last Maryland base rate case. Once the amounts have been allocated by cost of service study rate schedule groupings, the "RAC" will be calculated by dividing the schedule's allocated dollars by its projected kWh for the next calendar year. 4) Potomac Edison will track the credits made to customer bills and reduce the balance in the deferred account on a monthly basis by the amount of those credits throughout the refund year. 5) Any over or under refund will be reflected in the deferred account balance for the following annual review. 7
