NSP-MINNESOTA IS A SIGNIFICANT SUBSIDIARY OF XCEL ENERGY INC. THE ACCIDENT OCCURRED AS A CREW FROM CABLE CONSTRUCTORS INC. (CCI) WAS INSTALLING FIBER OPTIC CABLE FOR SEREN. SEREN IS A SUBSIDIARY OF XCEL ENERGY INC. SEREN, CCI AND SIRTI, AN ARCHITECTURE/ENGINEERING FIRM RETAINED BY SEREN, ARE NAMED AS DEFENDANTS IN TEN LAWSUITS RELATING TO THE EXPLOSION. NSP-MINNESOTA IS A DEFENDANT IN EIGHT OF THE LAWSUITS. NSP-MINNESOTA AND SEREN DENY ANY LIABILITY FOR THIS ACCIDENT. NSP-MINNESOTA HAS A SELF-INSURED RETENTION DEDUCTIBLE OF $2 MILLION WITH GENERAL LIABILITY COVERAGE LIMITS OF $185 MILLION. SEREN'S PRIMARY INSURANCE COVERAGE IS $1 MILLION AND ITS SECONDARY INSURANCE COVERAGE IS $185 MILLION. THE ULTIMATE COST TO XCEL ENERGY INC., NSP-MINNESOTA AND SEREN, IF ANY, IS UNKNOWN AT THIS TIME.

IN APRIL 1997, A FIRE DAMAGED SEVERAL BUILDINGS IN DOWNTOWN GRAND FORKS, N. D., DURING A FLOOD IN THE CITY. ON JULY 23, 1998, THE ST. PAUL MERCURY INSURANCE CO. COMMENCED A LAWSUIT AGAINST NSP-MINNESOTA FOR DAMAGES IN EXCESS OF $15 MILLION. NSP-MINNESOTA IS A SIGNIFICANT SUBSIDIARY OF XCEL ENERGY INC. THE SUIT WAS FILED IN THE DISTRICT COURT IN GRAND FORKS COUNTY IN

101

NORTH DAKOTA. THE INSURANCE COMPANY ALLEGED THE FIRE WAS ELECTRICAL IN ORIGIN AND THAT NSP-MINNESOTA WAS LEGALLY RESPONSIBLE FOR THE FIRE BECAUSE IT FAILED TO SHUT OFF ELECTRICAL POWER TO DOWNTOWN GRAND FORKS DURING THE FLOOD AND PRIOR TO THE FIRE. SEVEN ADDITIONAL LAWSUITS WERE FILED AGAINST NSP-MINNESOTA BY INSURANCE COMPANIES WHICH INSURED BUSINESSES DAMAGED BY THE FIRE. ONE ADDITIONAL LAWSUIT FILED BY THE FIRST NATIONAL BANK OF GRAND FORKS IS VENUED IN FEDERAL COURT. THE TOTAL OF DAMAGES BEING SOUGHT BY ALL THESE LAWSUITS IS IN EXCESS OF $30 MILLION. NSP-MINNESOTA DENIED ANY LIABILITY, ASSERTING THAT IT WAS NOT LEGALLY RESPONSIBLE FOR THIS UNFORESEEABLE EVENT. TRIAL CONCERNING THE STATE COURT LAWSUITS COMMENCED ON AUG. 1, 2000, AND CONCLUDED ON SEPT. 7, 2000. ON SEPT. 8, 2000, AFTER DELIBERATING FOR ONLY ONE HOUR, A JURY RETURNED A DEFENSE VERDICT IN FAVOR OF NSP-MINNESOTA. IT IS UNKNOWN WHETHER THE PLAINTIFFS WILL APPEAL. NSP-MINNESOTA HAS A SELF-INSURED RETENTION DEDUCTIBLE OF $2 MILLION, WITH GENERAL LIABILITY INSURANCE COVERAGE LIMITS OF $150 MILLION. THE ULTIMATE COST TO XCEL ENERGY AND NSP-MINNESOTA, IF ANY, IS UNKNOWN AT THIS TIME.

JOHNSON ALLEGES THAT HE SUFFERED PERSONAL INJURY AS A RESULT OF RUTS CREATED ON HIS PROPERTY BY NSP-W WHILE NSP-W WAS REPAIRING A POWER LINE LOCATED ADJACENT TO HIS PROPERTY. MR. JOHNSON ALLEGES THAT AS A RESULT OF HIS PERSONAL INJURY HE HAS SUSTAINED DAMAGES OF APPROXIMATELY $371 MILLION. NSP-W BELIEVES THE CLAIM IS DEFENSIBLE AND ANY DAMAGES OR COSTS RESULTING FROM THE ACTION WILL NOT BE MATERIAL.

ON JUNE 8, 1998, NSP FILED A COMPLAINT IN THE COURT OF FEDERAL CLAIMS AGAINST THE DEPARTMENT OF ENERGY (DOE) REQUESTING DAMAGES IN EXCESS OF $1 BILLION FOR THE DOE'S PARTIAL BREACH OF THE STANDARD CONTRACT. NSP REQUESTED DAMAGES CONSISTING OF THE COSTS OF STORAGE OF SPENT NUCLEAR FUEL AT THE PRAIRIE ISLAND NUCLEAR GENERATING PLANT, ANTICIPATED COSTS RELATED TO THE PRIVATE FUEL STORAGE, LLC AND COSTS RELATING TO THE 1994 STATE LEGISLATION LIMITING THE NUMBER OF CASKS THAT CAN BE USED TO STORE SPENT NUCLEAR FUEL AT PRAIRIE ISLAND. ON APRIL 6, 1999, THE COURT OF FEDERAL CLAIMS DISMISSED NSP'S COMPLAINT. ON MAY 20, 1999, NSP FILED A NOTICE OF APPEALS WITH THE FEDERAL CIRCUIT AND ON JULY 20, 1999, NSP FILED ITS INITIAL BRIEF ON APPEAL. THE DEPARTMENT OF JUSTICE, REPRESENTING THE UNITED STATES, FILED ITS INITIAL BRIEF ON OCT. 29, 1999. NO DATE HAS BEEN SET FOR ORAL ARGUMENT. A DECISION IS EXPECTED IN MID-2000.

ON AUG. 7, 1998, A GROUP OF RESIDENTIAL AND COMMERCIAL CUSTOMERS BROUGHT A CLASS ACTION LAWSUIT AGAINST THE DOE IN THE FEDERAL DISTRICT COURT IN MINNEAPOLIS, MINN. THE SUIT DEMANDS THE RETURN OF MONIES PAID BY CUSTOMERS INTO THE NUCLEAR WASTE FUND AND OTHER DAMAGES, BASED ON THE FAILURE OF THE DOE TO MEETS ITS UNCONDITIONAL OBLIGATION TO ACCEPT SPENT NUCLEAR FUEL BY JAN. 31, 1998. NSP IS NAMED AS NOMINAL DEFENDANT BECAUSE NSP HAS THE CONTRACT WITH THE DOE UNDER WHICH PAYMENTS ARE MADE INTO THE FUND. ON DEC. 23, 1999, THE COURT DISMISSED THE CLASS ACTION SUIT. THE MATTER IS CURRENTLY ON APPEAL.

NSP RECORDED A CHARGE OF $35 MILLION (BEFORE TAX), OR APPROXIMATELY 14 CENTS PER SHARE, IN THE SECOND QUARTER OF 1999 AS A RESULT OF A MINNESOTA PUBLIC UTILITIES COMMISSION (MPUC) DISALLOWANCE OF RATE RECOVERY OF ACCRUED 1998 CONSERVATION PROGRAM INCENTIVES.

102

IN 1997, NSP WAS SERVED WITH A SUMMONS AND COMPLAINT ON BEHALF OF THE OWNERS OF SCHACHTNER FARMS LOCATED IN DEER PARK, WIS. THE COMPLAINT ALLEGED THAT STRAY VOLTAGE FROM NSP'S SYSTEM HARMED THEIR DAIRY HERD, RESULTING IN LOST MILK PRODUCTION, INJURY TO THE DAIRY HERD, LOST PROFITS AND INCREASED VETERINARY EXPENSES. ON NOV. 23, 1999, THE JURY RETURNED A VERDICT FINDING NSP NEGLIGENT AND AWARDING SCHACHTNER FARMS $850,000 FOR ECONOMIC DAMAGES AND $200,000 FOR INCONVENIENCE, ANNOYANCE AND LOSS OF USE AND ENJOYMENT OF THEIR PROPERTY PLUS COSTS AND INTEREST. THE COURT TREBLED THE DAMAGES BECAUSE THE JURY FOUND THAT NSP WAS WILLFUL, WANTON OR RECKLESS IN ITS FAILURE TO PROVIDE ADEQUATE SERVICE TO THE FARM. NSP HAS APPEALED THE DECISION TO THE COURT OF APPEALS, THIRD DISTRICT, OF THE STATE OF WISCONSIN. NSP-W ANTICIPATES THAT INSURANCE WILL INDEMNIFY IT FOR ALL DAMAGES AND COSTS SUBJECT TO APPLICABLE INSURANCE POLICY DEDUCTIBLES.

PUBLIC SERVICE COMPANY OF COLORADO IS A SIGNIFICANT SUBSIDIARY. THESE CORPORATE OWNED LIFE INSURANCE (COLI) POLICIES WERE ENTERED INTO PRIOR TO JUNE 20, 1986. SINCE 1986, CONGRESS HAS PASSED VARIOUS LEGISLATION TO PHASE OUT THE TAX BENEFITS ASSOCIATED WITH CERTAIN COLI POLICIES, HOWEVER, PSRI'S POLICIES HAVE BEEN GRANDFATHERED UNDER THIS LEGISLATION. IN AUG. 1998, THE UNITED STATES INTERNAL REVENUE SERVICE (IRS) ISSUED A NOTICE OF PROPOSED ADJUSTMENT PROPOSING TO DISALLOW THE 1993 AND 1994 DEDUCTIONS OF INTEREST EXPENSE RELATED TO POLICY LOANS ON THE COLI POLICIES. IN MARCH 2000, THE IRS AMENDED ITS ORIGINAL ADJUSTMENT TO ALSO DISALLOW THE INTEREST DEDUCTIONS TAKEN IN TAX YEARS 1995 THROUGH 1997. THE TOTAL DISALLOWANCE OF INTEREST EXPENSE DEDUCTIONS FOR THE FIVE YEARS AS PROPOSED BY THE IRS IS APPROXIMATELY $175 MILLION. A REQUEST FOR TECHNICAL ADVICE FROM THE IRS NATIONAL OFFICE WITH RESPECT TO THE PROPOSED ADJUSTMENT IS PENDING. PSRI IS VIGOROUSLY CONTESTING THIS ISSUE. PSRI HAS NOT RECORDED ANY PROVISION FOR INCOME TAX OR INTEREST EXPENSE RELATED TO THIS MATTER AND HAS CONTINUED TO TAKE DEDUCTIONS FOR INTEREST EXPENSE RELATED TO POLICY LOANS ON ITS INCOME TAX RETURNS FOR SUBSEQUENT YEARS.
