-5- Note 2. Regulatory Matters FPSC Refund Order in Connection with 1991 Rate Case. Responding to a Florida Supreme Court decision addressing the issue of retroactive ratemaking with respect to another company, in March 1996 the FPSC voted to reconsider an October 1995 order (Refund Order) which would have required Florida Water to refund about $15 million, which includes interest, to customers who paid more since October 1993 under uniform rates than they would have paid under stand-alone rates. Under the Refund Order, the collection through a surcharge of the $15 million from customers who paid less under uniform rates was not permitted. The Refund Order was in response to the Florida First District Court of Appeals (Court of Appeals) reversal in April 1995 of the 1993 FPSC order which imposed uniform rates for most of Florida Water's service areas in Florida. With "uniform rates," all customers in the uniform rate areas pay the same rates for water and wastewater services. Uniform rates are an alternative to "stand-alone" rates which are calculated based on the cost of serving each service area. The FPSC reconsidered the Refund Order, but in August 1996 the FPSC issued an order upholding by a 3 to 2 vote its decision to order refunds without offsetting surcharges. Florida Water filed an appeal of this decision with the Court of Appeals. On June 17, 1997 the Court of Appeals reversed the FPSC's August 1996 order. The Court of Appeals determined that the FPSC's order directing the refund without permitting an offsetting surcharge was not permissible because it did not comport with principles of equity or with existing Florida Supreme Court precedent. The Court of Appeals remanded the matter back to the FPSC for reconsideration, and directed the FPSC to consider requests for intervention from the various customer groups impacted by any potential surcharges. The issues to be considered on remand relate to rate design and do not involve any adjustment to Florida Water's revenue requirement. The Company has not recorded a provision for refund in connection with this case. The Company is unable to predict the outcome of this matter. Florida Water's 1995 Rate Case. Florida Water requested an $18.1 million rate increase in June 1995 for all water and wastewater customers of Florida Water regulated by the FPSC. On October 30, 1996 the FPSC issued its final order in the Florida Water rate case. The new rates, which became effective as of September 20, 1996, resulted in an annualized increase in revenue of approximately $11.1 million. This increase included, and was not in addition to, the $7.9 million increase in annualized revenue granted as interim rates effective on January 23, 1996. The FPSC approved a new rate structure called "capband," which replaces uniform rates. With capband rates, areas with similar cost of service are grouped into one of a number of rate bands, and all customers within a given band are charged the same rate. This rate structure is designed so that a customer's bill will not exceed a certain "cap" unless the customer's usage exceeds an assumed level. On November 1, 1996 Florida Water filed with the Court of Appeals an appeal of the FPSC's final order seeking judicial review of issues relating to the amount of investment in utility facilities recoverable in rates from current customers. Other parties to the rate case also filed appeals with the Court of Appeals regarding the FPSC's final order. The Company is unable to predict the outcome of this matter. Effective June 13, 1997 Florida Water resumed collecting pre-existing Allowance for Funds Prudently Invested (AFPI) charges. AFPI represents the accrued carrying cost of certain non-used and useful property excluded from rate base and is collected as a one-time charge to certain new water and wastewater customers. The recovery of AFPI charges at certain Florida Water service areas was reduced or eliminated in the FPSC's October 1996 final order issued in connection with Florida Water's 1995 rate case. In April 1997 the FPSC, acting on Florida Water's motion, allowed recovery of pre-existing AFPI charges for these service areas, subject to refund with interest in the event of an adverse court ruling in the appeal of the 1995 rate case. Florida Water estimates approximately $1 million, on an annual basis, will be collected and accounted for as deferred revenue pending results of the appeal. Hernando County Rates. As required by Hernando County, on April 14, 1997 Florida Water filed for a rate change with the Hernando County Board of Commissioners. Florida Water filed for an annual interim rate reduction of $258,780 (-3.3 percent) and a final rate increase of $123,897 (1.6 percent). On June 14, 1997 the final rate increase Florida Water requested became effective automatically by operation of law because Hernando County failed to take action on the rates within the prescribed statutory period. -6- Note 2. Regulatory Matters (Continued) In July 1997 Florida Water reached a settlement agreement with Hernando County regarding the rate case Florida Water filed in April 1997. Under the settlement agreement, new rates will be effective September 1, 1997 and are expected to result in $6.3 million of revenue on an annual basis, a $1.6 million decrease from current revenue levels implemented on June 14, 1997. Rates will then be increased January 1, 1999 to result in $7.2 million in revenue on an annual basis. Florida Water has also agreed not to file for new rates with Hernando County prior to September 2000. All litigation was dismissed by both parties. Florida Water's settlement agreement with Hernando County supersedes the FPSC's February 14, 1997 order which required Florida Water to charge rates to customers in Hernando County based on a modified stand-alone rate structure. Hillsborough County Rates. On July 2, 1997 Florida Water filed for a rate change with the Hillsborough County Utilities Department. Florida Water filed for an annual interim rate increase of $848,845 (43.1 percent) and a final rate increase of $877,607 (44.6 percent). Interim rates are anticipated to become effective 45 days from the date of the filing. The Company is unable to predict the outcome of this case. Index Filings. In July 1997 Florida Water filed two index filings which if approved will increase revenue by $436,000. Approval is expected on or about October 1, 1997. Under Florida law water and wastewater utilities may make an annual index filing designed to recover inflationary costs associated with operation and maintenance expense. Note 3. Square Butte Purchased Power Contract The Company has a contract to purchase power and energy from Square Butte. Under the terms of the contract which extends through 2007, the Company is purchasing 71 percent of the output from a generating plant which is capable of generating up to 470 MW. Reductions to about 49 percent of the output are provided for in the contract and, at the option of Square Butte, could begin after a five-year advance notice to the Company. The cost of the power and energy is a proportionate share of Square Butte's fixed obligations and variable operating costs, based on the percentage of the total output purchased by the Company. The annual fixed obligations of the Company to Square Butte are $20.1 million from 1997 through 2001. The variable operating costs are not incurred unless production takes place. The Company is responsible for paying all costs and expenses of Square Butte if not paid by Square Butte when due. These obligations and responsibilities of the Company are absolute and unconditional whether or not any power is actually delivered to the Company. Note 4. Income Tax Expense

-7- Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Minnesota Power has operations in four business segments: (1) electric operations, which include electric and gas services, and coal mining; (2) water services, which include water and wastewater services; (3) automotive services, which include auctions, a finance company and an auto transport company; and (4) investments, which include a securities portfolio, a 21 percent equity investment in a financial guaranty reinsurance company, and real estate operations. Earnings per share of common stock for the quarter ended June 30, 1997 were 60 cents compared to 49 cents for the quarter ended June 30, 1996. Significant increases from electric operations and automotive services were the primary contributors to higher earnings in 1997. Higher earnings from electric operations include compensation from the Company's sale of its rights to microwave frequencies and property tax relief from the State of Minnesota. Automotive services earnings are higher due to a 28 percent increase in the number of cars sold at ADESA's auctions and the expansion of AFC's floor plan financing business. In 1996 portfolio and reinsurance included a one-time tax benefit for an IRS audit adjustment. Earnings per share of common stock for the six months ended June 30, 1997 were $1.12 compared to $1.10 for the six months ended June 30, 1996. Earnings in 1997 reflect a significant increase in automotive services due to a 28 percent increase in the number of cars sold at ADESA's auctions and the expansion of AFC's floor plan financing business. 1997 earnings also reflect a solid performance from electric operations and consistent performance by the portfolio and reinsurance portion of the investments segment. In 1996 portfolio and reinsurance included a one-time tax benefit for an IRS audit adjustment. Corporate charges and other reflect increased debt service costs as a result of the higher balance of commercial paper in 1997 and six months of distributions with respect to the Cumulative Quarterly Income Preferred Securities issued in March 1996. Earnings in 1996 include a gain in water services from the sale of water assets and the sale of a joint venture interest by real estate.

Consolidated Financial Comparison Quarters Ended June 30, 1997 and 1996. Operating revenue and income was up $21.9 million (10.5 percent) due primarily to an increase in the number of cars sold at ADESA's auctions. An increase in real estate sales also contributed to the increase in operating revenue and income. Fuel and purchased power were down $2.3 million (4.8 percent) because of a 16 percent decrease in generation at the Company's coal fired generating stations due to unscheduled outages and a 9 percent reduction in power purchased from other suppliers. The price of purchased power was substantially higher per megawatthour because of a limited supply available for purchase and additional transmission fees assessed for the delivery of power within the Midwest. -8- Operations expenses were up $11.3 million (8.8 percent), reflecting the expansion of ADESA's automobile auction operations, AFC, ISI and Palm Coast. Interest expense was higher in 1997 due primarily to a higher balance of commercial paper. Income tax expense was significantly higher in 1997 due to the $11.7 million increase in operating income and the recognition of a $2 million tax benefit by Lehigh in 1996. Consolidated Financial Comparison Six Months Ended June 30, 1997 and 1996. Operating revenue and income was up $41.3 million (10 percent), primarily due to the addition of ADESA's nine new auction sites and increased car sales at existing ADESA auctions. Also, revenue from water services was higher in 1997 because of increased rates approved by the FPSC effective in September 1996. The increase was partially offset by lower revenue following the sale of two water systems by Heater in 1996. A $1.1 million pre-tax gain on the sale of one water system in South Carolina was recognized in March 1996. Operations expenses were up $29.8 million (12.1 percent). The increase reflected $14.1 million of expenses from the eight automobile auction sites added by ADESA in 1996 and one auction site added in 1997. The expansion of AFC, and acquisitions of ISI and Palm Coast, also increased operations expense in 1997. Interest expense was higher in 1997 due primarily to more commercial paper issued. Distributions on redeemable preferred securities of subsidiary were higher in 1997 because the securities were outstanding for the six months in 1997 compared to less than four months in 1996. Income tax expense was significantly higher in 1997 due to the $9.3 million increase in operating income and the recognition of a $2 million tax benefit by Lehigh in 1996. Business Segment Comparison Quarters Ended June 30, 1997 and 1996. Electric Operations. Operating revenue and income was up slightly in 1997. Proceeds from the sale of rights to microwave frequencies and the sale of river land to the State of Minnesota offset a decline in revenue from an 11 percent decrease in total kilowatthour sales. Kilowatthour sales for resale by MPEX, the Company's power marketing division, were down 40 percent in 1997 due to less power available for resale. Less power was available because of higher prices for purchased power, various generating unit outages, reduction in transmission capability damaged by severe spring storms in the Midwest and less hydro generation in Canada. While revenue from MPEX sales was lower in 1997, higher profit margins were realized on these sales. Revenue from electric sales to taconite customers accounted for 31 percent of electric operating revenue in 1997 compared to 33 percent in 1996. Electric sales to paper and other wood-products companies accounted for 12 percent of electric operating revenue in 1997 and 11 percent in 1996. Sales to other power suppliers accounted for 12 percent of electric operating revenue in 1997 compared to 15 percent in 1996. Total electric operating expenses decreased by $5.2 million in 1997 including a $2.3 million decrease in fuel and purchased power because of reduced kilowatthour sales. Recent reform of the Minnesota property tax system also reduced operating expenses in 1997. Water Services. Operating revenue and income from water services was lower in 1997 primarily due to lower revenue following the sale of two water systems by Heater in 1996 and lower consumption by customers in Florida and North Carolina. Operating expenses were also lower because of ongoing cost controls and improved operating efficiency. -9- Automotive Services. Operating revenue and income was $19.2 million higher in 1997 due primarily to the addition of nine new automobile auction sites and increased sales at existing sites. ADESA sold 204,000 cars in 1997 compared to 160,000 in 1996. Growth of AFC's floor plan financing business and increased transport business also increased revenue and income. Operating expenses were higher in 1997 because of the addition of nine auction sites and increased activity at existing sites. The expansion of AFC's floor plan financing business also contributed to higher operating expenses. Investments. - Securities Portfolio and Reinsurance. The Company's securities portfolio and reinsurance continued to perform well in 1997 as in 1996. Capital Re's contribution to earnings increased in 1997. A one-time tax benefit for an IRS audit adjustment was included in 1996. - Real Estate Operations. Revenue was up in 1997 as a result of additional sales of properties at Palm Coast. Expenses also were higher due to expanded operations. The recognition of $2 million of tax benefits at Lehigh in 1996 made real estate's contribution to net income higher in 1996 than 1997. Business Segment Comparison Six Months Ended June 30, 1997 and 1996. Electric Operations. Operating revenue and income from electric operations was up slightly in 1997. Proceeds from the sale of rights to microwave frequencies and the sale of river land to the State of Minnesota offset a decline in revenue resulting from a 7 percent decrease in total kilowatthour sales. The decrease is attributed to a decline in sales to other power suppliers due to less power available for resale. Less power was available because of higher prices for purchased power, various generating unit outages, reduction in transmission capability damaged by severe spring storms in the Midwest and less hydro generation in Canada. The decrease in kilowatt sales was partially offset by an increase in sales to paper customers because of a higher demand for paper. Revenue from electric sales to taconite customers accounted for 32 percent of electric operating revenue in 1997 and 1996. Electric sales to paper and other wood-products companies accounted for 12 percent of electric operating revenue in 1997 and 11 percent in 1996. Sales to other power suppliers accounted for 10 percent of electric operating revenue in 1997 compared to 12 percent in 1996. Total electric operating expenses decreased by $5.2 million in 1997 including a $1.9 million decrease in fuel and purchased power because of reduced kilowatthour sales. Lower property taxes due to the 1997 reform of the Minnesota property tax system and lower interest charges also contributed to the cost reductions in 1997 operating expenses. Water Services. Operating revenue and income from water services was higher in 1997 primarily because of increased rates approved by the FPSC in 1996 for Florida Water customers. The increase was partially offset by lower revenue following the sale of two water systems by Heater in 1996. A $1.1 million pre-tax gain on the sale of one water system in South Carolina was recognized in March 1996. Automotive Services. Operating revenue and income was $40 million higher in 1997 due primarily to the addition of nine new automobile auction sites and increased sales at existing sites. ADESA sold 391,000 cars in 1997 compared to 305,000 in 1996. Growth of AFC's floor plan financing business, increased transport business and a gain on the sale of an auction also increased revenue and income. Operating expenses were higher in 1997 because of the addition of nine auction sites and increased activity at existing sites. The expansion of AFC's floor plan financing business also contributed to higher operating expenses. -10- Investments. - Securities Portfolio and Reinsurance. The Company's securities portfolio and reinsurance earned an annualized after tax return of 8.6 percent in 1997 compared to 9.8 percent in 1996. A one-time tax benefit for an IRS audit adjustment was included in 1996. - Real Estate Operations. Revenue was down in 1997 compared to 1996 which included $3.7 million from the sale of Lehigh's joint venture investment in a resort and golf course. The April 1996 acquisition of Palm Coast increased 1997 operating revenue and expenses. The recognition of $2 million of tax benefits at Lehigh in 1996 made real estate's contribution to net income higher in 1996 than 1997. Liquidity and Financial Position Reference is made to the Consolidated Statement of Cash Flows for the six months ended June 30, 1997 and 1996, for purposes of the following discussion. Cash Flow Activities. Cash from operating activities was affected by a number of factors representative of normal operations. Working capital, if and when needed, generally is provided by the sale of commercial paper. In addition, securities investments can be liquidated to provide funds for reinvestment in existing businesses or acquisition of new businesses, and approximately 4 million original issue shares of Common Stock are available for issuance through the DRIP. AFC has sold a total of $75 million of receivables to a third party purchaser since December 1996, including $25 million in May 1997. Under the terms of a five year agreement, the purchaser agrees to make investments aggregating $100 million, at any one time outstanding, to the extent that such investments are supported by eligible receivables. Proceeds from the sale of the receivables were used to repay borrowings from the Company. In June 1997 Minnesota Power refinanced $10 million of industrial development revenue bonds and $29 million of pollution control bonds with $39 million of Variable Rate Demand Revenue Refunding Bonds Series 1997A due June 1, 2020, Series 1997B and Series 1997C due June 1, 2013 and Series 1997D due December 1, 2007. A total of $36.5 million of the transaction was completed in June and July. The remaining $2.5 million of the refinancing is expected to be completed by October 1997. In May 1997 MP Water Resources' $30 million 10.44% long-term note payable was refinanced with $24 million of Florida Water's First Mortgage Bonds, 8.01% Series due May 30, 2017 and $6 million of internally generated funds. Capital Requirements. Consolidated capital expenditures for the six months ended June 30, 1997 totaled $34 million. These expenditures include $17 million for electric operations, $10 million for water services and $7 million for automotive services. Internally generated funds were the primary source for funding capital expenditures. New Accounting Standards In June 1997 the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive Net Income", effective for fiscal years beginning after December 15, 1997. While earlier application is permitted, the Company does not intend to do so. SFAS 130 establishes standards for reporting and display of comprehensive income in a full set of general-purpose financial statements. Comprehensive income is defined as the change in equity during a period from all transactions and other events from nonowner sources. The adoption of SFAS 130 is not expected to impact the Company's financial position or results of operations. -11- Also in June 1997 the FASB issued SFAS 131, "Disclosures about Segments of an Enterprise and Related Information", effective for fiscal years beginning after December 15, 1997. SFAS 131 requires the reporting of certain information about operating segments of an enterprise. The Company believes that it is already in compliance with SFAS 131 in all material respects. In February 1997 the FASB issued SFAS 128, "Earnings per Share," effective for financial statements for both interim and annual periods ending after December 15, 1997. Earlier application is not permitted. SFAS 128 specifies the computation, presentation and disclosure requirements for earnings per share (EPS). The objective of the new standard is to simplify the computation of EPS and make the U.S. standard for this computation more compatible with the EPS standards of other countries and with that of the International Accounting Standards Committee. The adoption of SFAS 128 is expected to be immaterial to the Company's results of operations. PART II. OTHER INFORMATION Item 4.

Unless otherwise indicated, cited references are to the Company's 1996 Form 10-K. Ref. Page 13. - Fifth Paragraph On June 30, 1997 the NCUC approved the transfer of LaGrange Waterworks Corporation (LaGrange) to Heater. The Company has agreed to exchange 96,000 shares of Common Stock for the outstanding shares of LaGrange. The public staff of the NCUC and the City of Fayetteville filed requests for reconsideration of the NCUC's approval of the transfer. LaGrange provides water services to approximately 5,300 customers near Fayetteville, NC. Ref. Page 13. - Following the Sixth Paragraph On June 2, 1997 operations officially began at MP Water Resources' newly formed subsidiary, Americas' Water Services Corporation (Americas' Water). Americas' Water, which is headquartered in Chicago, Illinois, offers management, operations and maintenance contract services and expertise to governments and industries throughout the Americas. MP Water Resources is a wholly owned subsidiary of the Company. Ref.

Florida Water filed for an annual interim rate reduction of $258,780 (-3.3 percent) and a final rate increase of $123,897 (1.6 percent). On June 14, 1997 the final rate increase Florida Water requested became effective automatically by operation of law because Hernando County failed to take action on the rates within the prescribed statutory period. In July 1997 Florida Water reached a settlement agreement with Hernando County regarding the rate case Florida Water filed in April 1997. Under the settlement agreement, new rates will be effective September 1, 1997 and are expected to result in $6.3 million of revenue on an annual basis, a $1.6 million decrease from current revenue levels implemented on June 14, 1997. Rates will then be increased January 1, 1999 to result in $7.2 million in revenue on an annual basis. Florida Water has also agreed not to file for new rates with Hernando County prior to September 2000. All litigation was dismissed by both parties. Florida Water's settlement agreement with Hernando County supersedes the FPSC's February 14, 1997 order which required Florida Water to charge rates to customers in Hernando County based on a modified stand-alone rate structure. Ref. Page 14. - Following the Second Paragraph On July 2, 1997 Florida Water filed for a rate change with the Hillsborough County Utilities Department. The Company filed for an annual interim rate increase of $848,845 (43.1 percent) and a final rate increase of $877,607 (44.6 percent). Interim rates are anticipated to become effective 45 days from the date of the filing. The Company is unable to predict the outcome of this case. In July 1997 Florida Water filed two index filings which if approved will increase revenue by $436,000. Approval is expected on or about October 1, 1997. Under Florida law water and wastewater utilities may make an annual index filing designed to recover inflationary costs associated with operation and maintenance expense. Ref. Page 16. - Fourth Paragraph Ref. 10-Q for the quarter ended March 31, 1997, Page 10 - Last Paragraph On May 15, 1997 ADESA acquired 100 percent of a new automobile auction in Sacramento, California. The Sacramento site is on 37 acres with five auction lanes. -13- ------------------------------------- Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995 In connection with the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 (Reform Act), the Company is hereby filing cautionary statements identifying important factors that could cause the Company's actual results to differ materially from those projected in forward-looking statements (as such term is defined in the Reform Act) made by or on behalf of the Company in this quarterly report on Form 10-Q, in presentations, in response to questions or otherwise. Any statements that express, or involve discussions as to expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, through the use of words or phrases such as "anticipates", "estimates", "expects", "intends", "plans", "predicts", "projects", "will likely result", "will continue", or similar expressions) are not statements of historical facts and may be forward-looking. Forward-looking statements involve estimates, assumptions, and uncertainties and are qualified in their entirety by reference to, and are accompanied by, the following important factors, which are difficult to predict, contain uncertainties, are beyond the control of the Company and may cause actual results to differ materially from those contained in forward-looking statements: (i) prevailing governmental policies and regulatory actions, including those of the FERC, the MPUC, the FPSC, the NCUC, the SCPSC and the PSCW, with respect to allowed rates of return, industry and rate structure, acquisition and disposal of assets and facilities, operation, and construction of plant facilities, recovery of purchased power, and present or prospective wholesale and retail competition (including but not limited to retail wheeling and transmission costs); (ii) economic and geographic factors including political and economic risks; (iii) changes in and compliance with environmental and safety laws and policies; (iv) weather conditions; (v) population growth rates and demographic patterns; (vi) competition for retail and wholesale customers; (vii) pricing and transportation of commodities; (viii) market demand, including structural market changes; (ix) changes in tax rates or policies or in rates of inflation; (x) changes in project costs; (xi) unanticipated changes in operating expenses and capital expenditures; (xii) capital market conditions; (xiii) competition for new energy development opportunities; and (xiv) legal and administrative proceedings (whether civil or criminal) and settlements that influence the business and profitability of the Company. Any forward-looking statements speaks only as of the date on which such statement is made, and the Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for management to predict all of such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. ------------------------------------- Item 6.

                                 ARTICLE SECOND

                         SECURITIES OF THE FOURTH SERIES

            Section  2.01.  Description  of Series.  There  shall be a series of
Securities designated "8.01% Series due May 30, 2017" (herein sometimes referred
to as the "Securities of the Fourth Series"),  each of which shall also bear the
descriptive title "First Mortgage Bond," shall contain suitable  provisions with
respect to the matters hereinafter in this Article specified and shall otherwise
be in the form attached to this Third  Supplemental  Indenture as Exhibit A. The
aggregate  principal  amount of  Securities  of the Fourth  Series  which may be
authenticated  and  delivered  under the  Indenture  is limited to  Twenty-Eight
Million Dollars ($28,000,000.00),  except as provided in Sections 205 and 206 of
the Original Indenture.  Securities of the Fourth Series shall mature on May 30,
2017 and shall be issued as fully registered  Securities in denominations of One
Hundred  Thousand  Dollars  and, at the option of the  Company,  in any integral
multiple or multiples  thereof  (the  exercise of such option to be evidenced by
the  execution  and delivery  thereof);  they shall bear interest at the rate of
8.01% per annum,  payable on November 30, 1997 for the period from and including
the original date of issuance thereof to November 30, 1997, and semi-annually on
May 30 and November 30 of each year thereafter until Maturity; the principal of,
premium,  if any, and interest on each said Security to be payable at the office
or agency of the  Company in Apopka,  Florida,  in such coin or  currency of the
United  States of America  as at the time of payment is legal  tender for public
and private  debts.  Securities  of the Fourth  Series  shall be dated as in the
Indenture  provided.  Interest on the  Securities  of the Fourth Series shall be
computed  on the basis of a 360-day  year of twelve  thirty-day  months.  If the
Company shall default in the payment of the principal of, or premium or interest
on, any Security of the Fourth  Series,  the Company  shall pay to the Holder of
such  Security  such  overdue  principal,  premium or  interest,  together  with
interest on such overdue  principal and (to the extent permitted by law) on such
overdue  premium or interest at that rate of interest that is the greater of (a)
two  percent  (2%) per annum above the rate borne by such  Security  immediately
prior to such default or (b) two percent (2%) over the rate of interest publicly
announced by Morgan  Guaranty Trust Company in New York, New York, as its "base"
or "prime" rate.

         The Regular Record Date referred to in Section 207 of the Indenture for
the payment of the interest on the  Securities of the Fourth  Series  payable on
any Interest  Payment Date shall be the first  Business Day next  preceding such
Interest Payment Date.

            Section  2.02.  Required  Redemptions  in the  Event of Prior  First
Mortgage  Bond  Redemptions.  If at any time and from time to time,  the Company
shall  notify the  Trustee  and any Holder of First  Mortgage  Bonds  issued and
outstanding under the First  Supplemental  Indenture or the Second  Supplemental
Indenture  (the "Prior First  Mortgage  Bonds") of the  occurrence of any one or
more of the events and conditions described in Sections 3.01(B),  3.01(C), 3.02,
3.03(A),  3.03(B),  3.03(C),  3.03(D), 3.05, 3.06, 3.09, 4.01(B), 4.01(C), 4.02,
4.03(A),   4.03(B),  4.03(C),  4.03(D),  4.05,  4.06  and  4.09  of  the  Second
Supplemental  Indenture,  then and in such  event it shall on the same such date
notify in writing (each a "Company  Special  Redemption  Notice") the Holders of
the Securities of the Fourth Series,

                                      -9-


which Company Special  Redemption Notice shall describe in reasonable detail the
event or  condition  which is the  basis  for such  Company  Special  Redemption
Notice.  Without  limiting  the  foregoing,  if the Company is required  for any
reason whatsoever to prepay, redeem,  purchase or otherwise retire (collectively
a "Special  Redemption")  the Prior First Mortgage  Bonds,  in whole or in part,
then, and in such event,  the Company shall, not more than 40 days nor less than
30 days prior to the date on which any such Special  Redemption is to occur (any
such date of Special  Redemption  being  herein  referred  to as a "Prior  First
Mortgage Bond Redemption  Date") give written notice (a "Company  Notice"):  (a)
specifying such fact, (b) identifying  such Prior First Mortgage Bond Redemption
Date, (c) stating that a premium may be payable in connection  with such Special
Redemption, and, if so, the estimated amount thereof, together with a reasonably
detailed  computation of such estimated  premium,  (d) identifying the amount of
Securities  required to be so  redeemed,  (e)  offering  to redeem an  aggregate
principal amount of Outstanding  Securities of the Fourth Series equal to (i) in
the case of Special Redemptions pursuant to Sections 3.01(B),  3.01(C), 3.03(A),
3.03(B),  3.03(C),  3.03(D), 3.05, 4.01(B),  4.01(C), 4.03(A), 4.03(B), 4.03(C),
4.03(D) and 4.05 of the Second Supplemental Indenture, a pro rata portion of the
amount of Securities required to be redeemed pursuant to such Sections, such pro
rata  portion to be based upon the ratio of (A) the then  Outstanding  aggregate
principal  amount  of the  Securities  of the  Fourth  Series  to (B)  the  then
Outstanding  aggregate  principal  amount of the Securities of the Fourth Series
and the Prior First Mortgage Bonds, and (ii) in the case of Sections 3.02, 3.06,
3.09, 4.02, 4.06 and 4.09 of the Second  Supplemental  Indenture,  the aggregate
principal  amount of the Securities of the Fourth  Series,  and (f) specifying a
date,  which  shall be not more than 20 days nor less than 10 days prior to such
Prior  First  Mortgage  Bond  Redemption  Date,  on  which  each  Holder  of the
Securities of the Fourth Series must accept or decline such offer of redemption.
Each Holder of the then  outstanding  Securities of the Fourth Series shall have
the right to accept such offer and require  redemption of the  Securities of the
Fourth  Series  held by such  Holder by written  notice to the  Company  and the
Trustee (a "Bondholder  Notice") given not later than the date specified in such
Company Notice.  The Company shall, on said Prior First Mortgage Bond Redemption
Date,  redeem on an equal and ratable basis with the Prior First  Mortgage Bonds
which are to be redeemed on such Prior First Mortgage Bond Redemption  Date, the
Securities of the Fourth Series  Outstanding under the Indenture held by Holders
which have so accepted such offer of redemption;  provided, however, that to the
extent the Holders of the  Securities  of any Series to be redeemed  pursuant to
this  Section  2.02 or pursuant to the  above-referenced  Sections of the Second
Supplemental  Indenture waive any right of redemption or elect not to accept the
Company's offer of redemption,  an additional  principal amount of Securities of
the other  Series,  in an amount equal to the amount so waived or as to which an
offer is not accepted, shall be redeemed,  distributed pro rata among such other
Series based upon the ratio described  above,  but excluding from clause (B) the
principal amount of the Securities of the Series with respect to which there has
been a waiver or an offer unaccepted, except to the extent waived by the Holders
of the Securities of such other Series; provided further, however, to the extent
the  Holders  of the  majority  of the  Securities  of the  Second  Series and a
majority of the Securities of the Third Series,  in each case then  Outstanding,
waive redemption  pursuant to the applicable Sections of the Second Supplemental
Indenture, then the Company shall have no obligation to redeem Securities of the
Fourth  Series  pursuant  to this  Section  2.02.  The  redemption  price of the
Securities of 

                                      -10-


the Fourth Series to be so redeemed on such Prior First Mortgage Bond Redemption
Date shall be an amount equal to 100% of the outstanding principal amount of the
Securities of the Fourth Series so to be redeemed and accrued  interest  thereon
to the date of  prepayment,  together  with a  premium  equal to the  Make-Whole
Amount,  determined as of two Business  Days prior to such Prior First  Mortgage
Bond Redemption Date.

            Section 2.03.  Optional  Prepayments  with  Make-Whole  Amount.  The
Company may, at its option,  upon notice as provided  below,  prepay at any time
all, or from time to time any part of,  Securities of the Fourth  Series,  in an
amount not less than 10% of the aggregate  principal amount of Securities of the
Fourth Series then outstanding in the case of a partial  prepayment,  at 100% of
the principal  amount so prepaid,  together with interest accrued thereon to the
date  of  such  prepayment,  plus  the  Make-Whole  Amount  determined  for  the
prepayment  date with respect to such  principal  amount.  The Company will give
each Holder of Securities of the Fourth Series  written  notice of each optional
prepayment  under this  Section 2.03 not less than thirty (30) days and not more
than  sixty (60) days  prior to the date  fixed for such  prepayment.  Each such
notice shall specify such date, the aggregate principal amount of the Securities
of the Fourth Series to be prepaid on such date,  the  principal  amount of each
Bond held by such Holder to be prepaid  (determined  in accordance  with Section
2.07),  and the interest to be paid on the prepayment  date with respect to such
principal amount being prepaid,  and shall be accompanied by a certificate of an
Authorized Officer as to the estimated  Make-Whole Amount due in connection with
such  prepayment  (calculated as if the date of such notice were the date of the
prepayment),  setting forth the details of such  computation.  Two Business Days
prior to such prepayment, the Company shall deliver to each Holder of Securities
of the Fourth  Series a  certificate  of an Authorized  Officer  specifying  the
calculation of such Make-Whole Amount as of the specified prepayment date.

            Section 2.04.  Required Prepayment in the Event of Certain Defaults.
So long as any  Securities of the Fourth Series remain  outstanding,  if (a) the
Company or any  Subsidiary  is in default (as principal or as guarantor or other
surety) in the payment of any  principal of or premium or  make-whole  amount or
interest on any  Indebtedness  that is  outstanding  in an  aggregate  principal
amount of at least  $5,000,000  beyond any period of grace provided with respect
thereto,  or (b) the Company or any Subsidiary is in default in the  performance
of or  compliance  with  any  term of any  evidence  of any  Indebtedness  in an
aggregate  outstanding  principal  amount  of at  least  $5,000,000  or  of  any
mortgage,  indenture or other agreement  relating thereto or any other condition
exists,  and as a consequence of such default or condition such Indebtedness has
become,  or has been  declared  (or one or more  Persons are entitled to declare
such  Indebtedness  to be), due and payable before its stated maturity or before
its  regularly  scheduled  dates  of  payment,  or (c) as a  consequence  of the
occurrence or continuation of any event or condition  (other than the passage of
time or the right of the Holder of  Indebtedness  to convert  such  Indebtedness
into equity  interests),  (i) the Company or any Subsidiary has become obligated
to purchase  or repay  Indebtedness  before its  regular  maturity or before its
regularly  scheduled  dates of payment  in an  aggregate  outstanding  principal
amount of at least  $5,000,000,  or (ii) one or more  Persons  have the right to
require the Company or any Subsidiary so to purchase or repay such Indebtedness,
then the Company shall promptly and in any event within two (2) Business Days of
the date of  

                                      -11-

occurrence  of any  such  event  notify  the  Trustee  and  the  Holders  of the
Securities of the Fourth Series and the Company shall redeem,  within sixty (60)
days thereafter and upon at least ten (10) days notice, all of the Securities of
the Fourth Series then  Outstanding,  together with interest  accrued thereon to
the  date  of  redemption,  plus  the  Make-Whole  Amount  determined  for  such
redemption date two Business Days prior thereto. Two Business Days prior to such
redemption,  the Company shall  deliver to each Holder of the  Securities of the
Fourth Series a certificate of an Authorized  Officer specifying the calculation
of such Make-Whole Amount as of the specified redemption date.

            Section 2.05. Required Prepayment in the Event of Certain Judgments.
So long as any  Securities of the Fourth Series remain  outstanding,  if a final
judgment  or  judgments  for the  payment  of money  aggregating  in  excess  of
$10,000,000 are rendered against one or more of the Company and its Subsidiaries
and which judgments are not, within sixty (60) days after entry thereof (or such
longer period as shall be permitted by the express terms of any such judgment or
judgments),  bonded,  discharged or stayed pending appeal, or are not discharged
within  sixty  (60) days (or such  longer  period as shall be  permitted  by the
express terms of any such judgment or  judgments)  after the  expiration of such
stay,  then the Company shall  promptly and in any event within two (2) Business
Days of the date of  occurrence  of any such event  notify the  Trustee  and the
Holders of the  Securities  of the Fourth  Series and the Company  shall redeem,
within sixty (60) days thereafter and upon at least ten (10) days notice, all of
the  Securities  of the Fourth Series then  Outstanding,  together with interest
accrued thereon to the date of redemption, plus the Make-Whole Amount determined
for such  redemption  date two Business  Days prior  thereto.  Two Business Days
prior to such  redemption,  the  Company  shall  deliver  to each  Holder of the
Securities  of  the  Fourth  Series  a  certificate  of  an  Authorized  Officer
specifying  the  calculation  of  such  Make-Whole  Amount  as of the  specified
redemption date.

            Section  2.06.  Required  Prepayment  in the Event of Certain  ERISA
Defaults. So long as any Securities of the Fourth Series remain outstanding,  if
(a) any Plan shall fail to satisfy the minimum funding standards of ERISA or the
Code  for any  plan  year or part  thereof  or a  waiver  of such  standards  or
extension of any  amortization  period is sought or granted under section 412 of
the Code,  (b) a notice of intent to  terminate  any Plan  shall have been or is
reasonably  expected to be filed with the PBGC or the PBGC shall have instituted
proceedings  under  ERISA  Section  4042 to  terminate  or  appoint a trustee to
administer  any Plan or the PBGC shall have  notified  the  Company or any ERISA
Affiliate  that a Plan may  become a subject  of any such  proceedings,  (c) the
aggregate  "amount of  unfunded  benefit  liabilities"  (within  the  meaning of
Section  4001(a)(18)  of ERISA) under all Plans,  determined in accordance  with
Title IV of  ERISA,  shall  exceed  $1,000,000,  (d) the  Company  or any  ERISA

any other such event or events,  could reasonably be expected to


                                      -12-


have a Material Adverse Effect, then the Company shall promptly and in any event
within two (2) Business  Days of the date of occurrence of any such event notify
the  Trustee  and the  Holders of the  Securities  of the Fourth  Series and the
Company shall redeem,  within sixty (60) days  thereafter  and upon at least ten
(10) days notice,  all of the Securities of the Fourth Series then  Outstanding,
together  with  interest  accrued  thereon to the date of  redemption,  plus the
Make-Whole  Amount  determined for such  redemption date two Business Days prior
thereto.  Two Business Days prior to such redemption,  the Company shall deliver
to each  Holder of the  Securities  of the  Fourth  Series a  certificate  of an
Authorized  Officer  specifying the calculation of such Make-Whole  Amount as of
the specified redemption date.

As used in this Section 2.06,  the terms  "employee  benefit plan" and "employee
welfare benefit plan" shall have the respective  meanings assigned to such terms
in Section 3 of ERISA.

            Section 2.07. Allocation of Partial Prepayments. In the case of each
partial  prepayment of the Securities of the Fourth Series, the principal amount
of the  Securities of the Fourth  Series to be prepaid shall be allocated  among
all  of  the  Securities  of the  Fourth  Series  at  the  time  outstanding  in
proportion, as nearly as practicable, to the respective unpaid principal amounts
thereof not theretofore called for prepayment.

            Section  2.08.  Maturity;  Surrender,  Etc.  In  the  case  of  each
prepayment of Securities of the Fourth Series  pursuant to this Article  Second,
the  principal  amount  of each of the  Securities  of the  Fourth  Series to be
prepaid  shall  be and  become  due and  payable  on the  date  fixed  for  such
prepayment, together with interest on such principal amount accrued to such date
and the applicable  Make-Whole  Amount, if any. From and after such date, unless
the Company  shall fail to pay such  principal  amount when so due and  payable,
together with the interest and Make-Whole Amount, if any, as aforesaid, interest
on such  principal  amount  shall  cease to accrue.  Any  Security of the Fourth
Series paid or prepaid in full shall be surrendered to the Company and cancelled
and shall not be reissued,  and no Security of the Fourth Series shall be issued
in lieu of any prepaid principal amount of any Security of the Fourth Series.

            Section  2.09.  Purchase of  Securities  of the Fourth  Series.  The
Company will not and will not permit any Affiliate to purchase,  redeem,  prepay
or otherwise acquire, directly or indirectly,  any of the outstanding Securities
of the Fourth Series except upon the payment or prepayment of the  Securities of
the  Fourth  Series  in  accordance  with the terms of this  Third  Supplemental
Indenture  and the  Securities of the Fourth  Series.  The Company will promptly
cancel all  Securities  of the Fourth  Series  acquired  by it or any  Affiliate
pursuant to any  payment,  prepayment  or purchase of  Securities  of the Fourth
Series  pursuant to any  provision of this Third  Supplemental  Indenture and no
Securities  of the Fourth Series may be issued in  substitution  or exchange for
any such Securities of the Fourth Series.

            Section 2.10. Make-Whole Amount. The term "Make-Whole Amount" means,
with  respect to any  Security  of the  Fourth  Series,  an amount  equal to the
excess, if any, of the Discounted Value of the Remaining Scheduled Payments with
respect to the Called  Principal of such  Security of the Fourth Series over the
amount of such Called  Principal;  provided

                                      -13-


that the  Make-Whole  Amount may in no event be less than zero. For the purposes
of determining  the Make-Whole  Amount,  the following  terms have the following
meanings:

                  "Called  Principal" means, with respect to any Security of the
         Fourth Series, the principal of such Security of the Fourth Series that
         is to be prepaid  pursuant to Section 2.02 (if the related  prepayment,
         redemption or retirement of Prior First  Mortgage  Bonds is made with a
         premium), Section 2.03, Section 2.04, Section 2.05, Section 2.06 or has
         become or is declared  to be  immediately  due and payable  pursuant to
         Section 1102 of the Original Indenture, as the context requires.

                  "Discounted Value" means, with respect to the Called Principal
         of  any  Security  of  the  Fourth  Series,   the  amount  obtained  by
         discounting  all  Remaining  Scheduled  Payments  with  respect to such
         Called  Principal  from  their  respective  scheduled  due dates to the
         Settlement  Date with respect to such Called  Principal,  in accordance
         with accepted  financial  practice and at a discount factor (applied on
         the same periodic  basis as that on which interest on the Securities of
         the Fourth  Series is  payable)  equal to the  Reinvestment  Yield with
         respect to such Called Principal.

                  "Reinvestment   Yield"  means,  with  respect  to  the  Called
         Principal of any Security of the Fourth Series, 0.50% over the yield to
         maturity implied by (a) the yields reported, as of 10:00 A.M. (New York
         City time) on the second  Business Day  preceding the  Settlement  Date
         with respect to such Called  Principal,  on the display  designated  as
         "Page USD" of the Bloomberg  Financial  Markets Services Screen (or, if
         not available,  any other national  recognized trading screen reporting
         on-line intraday trading in the U.S. Treasury  securities) for actively
         traded  U.S.  Treasury  securities  having  a  maturity  equal  to  the
         Remaining  Average Life of such Called  Principal as of such Settlement
         Date,  or (b) if such  yields are not  reported  as of such time or the
         yields  reported as of such time are not  ascertainable,  the  Treasury
         Constant Maturity Series Yields reported,  for the latest day for which
         such  yields  have  been so  reported  as of the  second  Business  Day
         preceding the Settlement Date with respect to such Called Principal, in
         Federal  Reserve  Statistical  Release  H.15  (519) (or any  comparable
         successor  publication)  for actively traded U.S.  Treasury  securities
         having a constant  maturity equal to the Remaining Average Life of such
         Called Principal as of such Settlement Date. Such implied yield will be
         determined,   if  necessary,  by  (i)  converting  U.S.  Treasury  bill
         quotations  to  bond-equivalent  yields  in  accordance  with  accepted
         financial  practice  and (ii)  interpolating  linearly  between (1) the
         actively traded U.S. Treasury security with the duration closest to and
         greater than the  Remaining  Average  Life and (2) the actively  traded
         U.S.  Treasury  security with the duration closest to and less than the
         Remaining Average Life.

                  "Remaining  Average  Life"  means,  with respect to any Called
         Principal,  the number of years (calculated to the nearest  one-twelfth
         year)  obtained by dividing (a) such Called  Principal into (b) the sum
         of the products obtained by multiplying (i) the principal  component of
         each Remaining  Scheduled Payment with respect to such Called Principal
         by (ii) the  number of years  (calculated  to the  nearest  one-

                                      -14-


         twelfth year) that will elapse between the Settlement Date with respect
         to such Called Principal and the scheduled due date of such Remaining 
         Scheduled Payment.

                  "Remaining  Scheduled  Payments"  means,  with  respect to the
         Called Principal of any Security of the Fourth Series,  all payments of
         such Called  Principal and interest thereon that would be due after the
         Settlement Date with respect to such Called  Principal if no payment of
         such  Called  Principal  were  made  prior to its  scheduled  due date;
         provided that if such  Settlement  Date is not a date on which interest

                     ADDITIONAL COVENANTS FOR FOURTH SERIES

            Section 3.01.  Debt  Covenant  Required  Redemption.  So long as any
Securities of the Fourth Series shall remain Outstanding, the Company shall file
with the Trustee,  on or before March 31 of each calendar year, an  Accountant's
Certificate showing as of December 31 of the immediately preceding calendar year
(1) the aggregate  principal  amount of Securities then  Outstanding and (2) the
net book value of property,  plant and equipment,  determined in accordance with
GAAP, which constitute Property Additions. If such aggregate principal amount of
Securities then Outstanding exceeds sixty per centum (60%) of the net book value
of such property, plant and equipment then the Company shall promptly notify the
Trustee  and, if there is only one Holder of  Securities  of the Fourth  Series,
such Holder;  and the Company shall redeem,  within ninety days  thereafter  and
upon at least thirty days' notice,  a principal amount of the Securities of such
Series then  Outstanding  equal to a pro rata portion of the amount necessary to
cause the aggregate  principal  amount of Securities  then  Outstanding to equal
sixty  per  centum  (60%) of the net  book  value of such  property,  plant  and
equipment,  such pro rata portion of such Series to be based upon a ratio of (A)
the then Outstanding  aggregate principal amount of Securities of such Series to
(B) the then Outstanding  aggregate  principal  amounts of the Securities of the
Second Series, of the Third Series and of the Fourth Series; provided,  however,
that to the extent any of the Holders of Securities of the Second Series, of the
Third  Series  or of the

                                      -15-

Fourth Series waive any right of redemption,  an additional  principal amount of
Securities of the other Series,  in an amount equal to the amount waived,  shall
be redeemed,  distributed  pro rata among such other Series based upon the ratio
described  above,  but  excluding  from clause (B) the  principal  amount of the
Securities  of the Series with respect to which there has been a waiver,  except
to the extent waived by the Holders of the Securities of such other Series.  The
Redemption Price of the Securities of the Fourth Series shall be the outstanding
principal  amount of the  Securities  of such Series to be redeemed  pursuant to
this  Section  3.01 plus the Make  Whole  Amount  plus  interest  accrued to the
Redemption  Date.  The  Holders of a majority  of the  Securities  of the Fourth
Series then  Outstanding may waive  redemption  pursuant to this Section 3.01 by
delivering a written  waiver to the Trustee,  in such form as the Trustee  shall
deem acceptable,  with a copy to the Company,  within ten days after the date of
such notice of redemption.

            Section 3.02.  Restricted Payments. So long as any Securities of the
Fourth  Series  remain  Outstanding,  the  Company  shall not declare or pay any
Restricted  Payments unless the Company files an Accountant's  Certificate  with
the Trustee and, if there is only one Holder of Securities of the Fourth Series,
sends a copy to such Holder,  within  thirty days prior to such  declaration  or
payment stating that (A) the amount of such payment shall not exceed  cumulative
net additions to or deductions from Surplus, determined in accordance with GAAP,
made after December 31, 1992 (excluding any gains on sale of Property  Additions
during the immediately  preceding 12 months in excess of twenty per centum (20%)
of the net additions to Surplus made during such 12 month period);  and (B) that
after such payment  Capital plus Surplus  shall equal at least  thirty-five  per
centum (35%) of Capitalization, determined in accordance with GAAP.

            Section 3.03.  Compliance with Law. The Company will, and will cause
each of its  Subsidiaries  to, comply with all laws,  ordinances or governmental
rules  or  regulations  to which  each of them is  subject,  including,  without
limitation,  Environmental  Laws,  and will  obtain and  maintain  in effect all
licenses,    certificates,    permits,   franchises   and   other   governmental
authorizations  necessary to the ownership of their respective  properties or to
the conduct of their respective businesses, in each case to the extent necessary
to ensure that non-compliance  with such laws,  ordinances or governmental rules
or  regulations  or failures  to obtain or  maintain  in effect  such  licenses,
certificates,  permits,  franchises and other governmental  authorizations could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

            Section 3.04.  Payment of Taxes and Claims.  The Company  will,  and
will cause each of its  Subsidiaries  to,  file all tax  returns  required to be
filed in any jurisdiction and to pay and discharge all taxes shown to be due and
payable on such returns and all other taxes, assessments,  governmental charges,
or  levies  imposed  on them  or any of  their  properties,  assets,  income  or
franchises, to the extent such taxes and assessments have become due and payable
and before they have become delinquent and all claims for which sums have become
due and payable that have or might become a Lien on  properties or assets of the
Company or any Subsidiary;  provided that neither the Company nor any Subsidiary
need pay any such tax or assessment  or claims if (a) the amount,  applicability
or validity  thereof is contested by the Company or such  Subsidiary on a timely
basis  in good  faith  and in  appropriate

                                      -16-


proceedings,  and the Company or a Subsidiary has established  adequate reserves
therefor in accordance  with GAAP on the books of the Company or such Subsidiary
or (b) the nonpayment of all such taxes and  assessments in the aggregate  could
not reasonably be expected to have a Material Adverse Effect.

            Section  3.05.  Securities  of the Fourth Series to Rank Pari Passu.
The Securities of the Fourth Series are and at all times shall remain direct and
secured  obligations of the Company  ranking pari passu as against the assets of

                          (iii) additional  Securities of the Company issued and
                  outstanding within the limitations of the Indenture;  provided
                  that at the time of creation, issuance, assumption,  guarantee
                  or incurrence  thereof and after giving effect  thereto and to
                  the application of the proceeds thereof:

                                     (1) Consolidated Indebtedness shall not 
                           exceed 65% of Consolidated Total Capitalization;

                                     (2) the  average  of the  Consolidated  Net
                           Income Available for  Consolidated  Fixed Charges for
                           the four immediately  preceding fiscal quarters shall
                           have  been  at  least  150%  of  the  average  of the
                           Consolidated  Fixed  Charges  for  such  four  fiscal
                           quarters; and

                                     (3) in the  case  of  the  issuance  of any
                           Indebtedness   of  the   Company   secured  by  Liens
                           permitted  by 704 of the Original  Indenture  and any
                           Indebtedness  of a  Subsidiary,  the  sum of (A)  the
                           aggregate amount of all Indebtedness secured by Liens
                           permitted by 704 of the Original  Indenture  plus (B)
                           the   aggregate   amount  of  all   Indebtedness   of
                           Subsidiaries  shall  not  exceed  5% of  Consolidated
                           Total Capitalization;

                                      -17-

                  to a Wholly-owned Subsidiary.

         issued,  incurred  or  outstanding  pursuant to Section  3.06(a)  shall
         constitute the issuance of additional  Indebtedness  which is, in turn,
         subject to the limitations of the applicable provisions of this Section
         3.06.

                   (c) Any  Person  which  becomes a  Subsidiary  after the date
         hereof  shall for all  purposes of this  Section 3.06 be deemed to have

         Subsidiary.

service by or for, any Affiliate), except in the ordinary course of and pursuant
to the reasonable  requirements of the Company's or such  Subsidiary's  business

Person other than an Affiliate.

            Section 3.08. Termination of Pension Plans. The Company will not and
will not permit any Subsidiary to withdraw from any Multiemployer Plan or permit

the Company or any Subsidiary pursuant to Section 4068 of ERISA.

            Section 3.09.  Limitations  on Restrictive  Agreements.  The Company
will not and will not permit any  Subsidiary to, enter into, or suffer to exist,
