These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audit. The financial statements of the Plan (formerly the Nicor Gas Savings Investment Plan) for the year ended December 31, 2000 were audited by other auditors, whose report, dated June 27, 2001 expressed an unqualified opinion on those statements. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, such 2001 financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2001 and the changes in net assets available for benefits for the year then ended in conformity with accounting principles generally accepted in the United States of America.

DESCRIPTION OF THE PLAN The following description of the Nicor Companies Savings Investment Plan (the Plan) provides only general information. Participants should refer to the Plan agreement for more detailed information. The Plan. The Plan is a defined contribution plan which was established on July 1, 1973, to provide supplemental retirement security to substantially all employees of Nicor Gas Company (the Company), not represented by a collective bargaining agreement. In 2001 the plan was amended to include employees of certain affiliated companies. Effective January 1, 2001, the Plan's name was changed from the Nicor Gas Savings Investment Plan to the Nicor Companies Savings Investment Plan. Plan investments are commingled with those of the Nicor Companies Thrift Plan and held for safekeeping and investment by the Nicor Gas Savings Investment and Thrift Trust (the Master Trust). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). Plan administration. Authority to control and manage the operation and administration of the Plan is vested in a committee appointed by the Board of Directors of the Company. Beginning on September 1, 2000, the Vanguard Fiduciary Trust Company acts as trustee for the Master Trust and holds the investments of the Plan under the terms of a trust agreement. The Vanguard Fiduciary Trust Company also acts as investment manager for certain assets of the Plan. For the first eight months of 2000, The Northern Trust Company acted in a similar capacity for the Master Trust and the investments of the Plan. Administrative expenses associated with operation of the Plan are paid from Plan assets. Contributions. The participant may elect to make either tax-deferred or after-tax contributions, or a combination thereof, by payroll deduction, that are partially matched by the Company. For employees hired on and after January 1, 1998, the Company makes an additional annual contribution subject to service requirements. The Plan also accepts rollover contributions representing distributions from other qualified plans. Participants direct the investment of their contributions and account balances into various investment options offered by the Plan. Investments. The Plan's investment options currently include the Nicor Stock Fund, the Nicor Stable Value Fund, and 22 mutual funds. Participant accounts. Individual accounts are maintained for each Plan participant. Each participant's account is increased by the participant's contributions, company contributions and allocated plan investment earnings, and decreased by withdrawals, allocated plan investment losses and administrative expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Participant loans. Participants may borrow from their account the lesser of $50,000 or 50 percent of their vested account balance. Loans are repaid through payroll deductions over periods ranging from six months to five years, and are secured by the balance in the participant's account. The interest rate is based on the prime rate plus 1 percent and is fixed over the life of the loan. 5 Nicor Companies Savings Investment Plan Notes to the Financial Statements (continued) For the Years Ended December 31, 2001 and 2000 Vesting and forfeitures. The participant's contributions and earnings thereon are immediately vested. Prior to December 31, 2001 the Company's contributions and earnings thereon were vested after the participant's completion of five years of service, the participant's death while employed by the Company or retirement. Beginning January 1, 2002, the Company's contributions and earnings thereon are vested after the participant's completion of three years of service, the participant's death while employed by the Company or retirement. If the participant's interest in the Company's contributions and earnings thereon is not vested, such interest will be forfeited if the participant's employment with the Company or an affiliate is terminated and the participant is not reemployed within five years by the Company or an affiliate. Any amounts forfeited by a participant are applied to reduce the amount of the Company's contributions under the Plan. Forfeitures for 2001 and 2000 totaled $148,215 and $51,603, respectively. Payment of benefits. On termination of service due to retirement, disability, or death, a participant may elect to receive either a lump-sum amount equal to the participant's vested interest in his or her account balance, or annual installments over a specified period. For termination of service for other reasons, a participant has the option to receive the value of the vested interest in his or her account as either a lump sum distribution or they can defer it to no later than the age of 70-1/2. Suspensions and withdrawals. The participant may suspend contributions and will not cease to be a participant during the suspension period. The participant may elect, under certain conditions, to withdraw participant contributions and earnings thereon prior to termination of employment. The Company's matching contributions and earnings thereon will not be distributed until the vested participant's attainment of age 59-1/2 or employment has been terminated. Plan termination. The Company expects to continue the Plan indefinitely, but reserves the right to amend or discontinue it at any time subject to the provisions of ERISA. In the event of plan termination, participants will become fully vested in their account balances. 2. ACCOUNTING POLICIES Use of estimates. The preparation of financial statements in accordance with accounting policies generally accepted in the United States of America requires management to make estimates that affect the reported amounts. Actual results could differ from those estimates. Investment valuation. The Plan states its investment in the Master Trust at the underlying value of the investments of the Master Trust as follows: The market value for Nicor Inc. common stock is based on the closing price on the New York Stock Exchange Composite Tape. The market value of the units of the common/collective trusts and registered investment companies are determined based on the underlying market value of the investments of the funds. 6 Nicor Companies Savings Investment Plan Notes to the Financial Statements (continued) For the Years Ended December 31, 2001 and 2000 The Nicor Stable Value Fund is primarily composed of benefit responsive investment contracts including insurance contracts and investments in certain registered investment companies and common/collective trusts whose contract values are guaranteed by bank contracts. These benefit responsive investment contracts are carried at contract value, which in aggregate approximates their fair market value. The contract value represents contributions made plus interest at the various contract rates, less Plan withdrawals and administrative expenses. The crediting interest rates for the registered investment companies and common/collective trusts are adjusted quarterly based upon their performance. The average crediting interest rate for the Nicor Stable Value Fund was 6.3 percent and 6.6 percent at December 31, 2001 and 2000, respectively. The average yield for this fund was approximately 6.3 percent and 6.7 percent for the years ended December 31, 2001 and 2000, respectively. There are no reserves against contract value for credit risk of the contract issuer or otherwise. Market risk. The Plan has investments that generally are exposed to various risks, such as interest rate, credit and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in their values will occur in the near term and such changes could materially affect the amounts reported in the statements of net assets available for benefits. 3. NET TRANSFER TO NICOR COMPANIES SAVINGS INVESTMENT PLAN When the status of a participant changes between union, employees covered by a collective bargaining agreement, and nonunion, employees not covered by a collective bargaining agreement, eligibility for participation shifts between the Nicor Companies Thrift Plan (the "union plan") and this Plan (the "nonunion plan"). When eligibility changes, the account balance of the participant is transferred to the corresponding plan. During 2001 and 2000, net transfers of $575,492 and $227,143, respectively, were made from the Nicor Companies Thrift Plan to the Nicor Companies Savings Investment Plan. 4. MASTER TRUST FINANCIAL INFORMATION Use of the Master Trust permits the commingling of the Plan's assets with the assets of the Nicor Companies Thrift Plan for investments and administrative purposes. Although assets of both plans are commingled in the Master Trust, the Trustee maintains supporting records for the purpose of allocating the net gain or loss of the investment account to the participating plans. The net investment income of the investment assets is allocated daily by the Trustee to each participating plan based on the relationship of the interest of each plan to the total of the interests of the participating plans. 7 Nicor Companies Savings Investment Plan Notes to the Financial Statements (continued) For the Years Ended December 31, 2001 and 2000 The following schedules present the Master Trust's net assets as of December 31, 2001 and 2000, the increase in the Master Trust's net assets derived from investment activities for the years then ended and the Plan's share of each: Net Assets in Master Trust December 31 ------------------------------ 2001 2000 ------------- ------------- Assets: General Investments: Group annuity contracts $ 87,466,170 $ 96,063,876 Common/collective trusts* 19,767,182 - Nicor Inc. common stock* 23,130,444 27,797,585 Registered investment companies* 121,619,065 135,135,569 Loans to participants* 4,600,116 4,714,506 ------------- ------------- 256,582,977 263,711,536 Liabilities: Operating payables 26,589 31,514 ------------- ------------- Net assets in Trust $ 256,556,388 $ 263,680,022 ============= ============= Plan's interest in Trust net assets $ 141,143,455 $ 144,122,876 ============= ============= Plan's percentage interest in Trust net assets 55% 55% ============= ============= * Party-in-interest investments. 8 Nicor Companies Savings Investment Plan Notes to the Financial Statements (concluded) For the Years Ended December 31, 2001 and 2000 Master Trust Investment Activities Year Ended December 31 ------------------------------ 2001 2000 ------------- ------------- Investment income: Interest $ 6,356,621 $ 7,917,238 Dividends 1,067,477 934,127 Net change in market value of Nicor Inc. common stock (1,237,633) 7,782,502 Net investment gain from common/collective trusts 767,182 859,623 Net investment loss from registered investment companies (6,654,800) (5,599,494) Demutualization proceeds and other 154,807 - ------------- ------------- 453,654 11,893,996 Administrative expenses (247,141) (273,581) ------------- ------------- Increase in Trust net assets derived from investment activities $ 206,513 $ 11,620,415 ============= ============= Plan's interest in Trust investment activities $ (482,223) $ 4,992,709 ============= ============= 5. INCOME TAXES The Internal Revenue Service has determined and informed the Company by a letter dated January 16, 1997, that the Plan and related Trust, as then designed, was tax exempt under Section 401(a) of the Internal Revenue Code (the Code). The Plan has been amended since receiving the determination letter; however, the Plan's management believes that the Plan and related Master Trust continue to be designed and operated in compliance with the requirements of the Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 9 NICOR COMPANIES THRIFT PLAN (FORMERLY NICOR GAS THRIFT PLAN) EMPLOYER IDENTIFICATION NO. 36-2863847 PLAN NO. 8 FINANCIAL STATEMENTS AS OF DECEMBER 31, 2001 AND 2000 TOGETHER WITH INDEPENDENT AUDITORS' REPORT 10 Independent Auditors' Report To the Nicor Companies Thrift Plan Committee: We have audited the accompanying statement of net assets available for benefits of Nicor Companies Thrift Plan (the "Plan") as of December 31, 2001 and the related statement of changes in net assets available for benefits for the year then ended.

The net investment income of the investment assets is allocated daily by the Trustee to each participating plan based on the relationship of the interest of each plan to the total of the interests of the participating plans. 16 Nicor Companies Thrift Plan Notes to the Financial Statements (continued) For the Years Ended December 31, 2001 and 2000 The following schedules present the Master Trust's net assets as of December 31, 2001 and 2000, the increase in the Master Trust's net assets derived from investment activities for the years then ended and the Plan's share of each: Net Assets in Master Trust December 31 ------------------------------ 2001 2000 ------------- ------------- Assets: General Investments: Group annuity contracts $ 87,466,170 $ 96,063,876 Common/collective trusts* 19,767,182 - Nicor Inc. common stock* 23,130,444 27,797,585 Registered investment companies* 121,619,065 135,135,569 Loans to participants* 4,600,116 4,714,506 ------------- ------------- 256,582,977 263,711,536 Liabilities: Operating payables 26,589 31,514 ------------- ------------- Net assets in Trust $ 256,556,388 $ 263,680,022 ============= ============= Plan's interest in Trust net assets $ 115,412,933 $ 119,557,146 ============= ============= Plan's percentage interest in Trust net assets 45% 45% ============= ============= * Party-in-interest investments. 17 Nicor Companies Thrift Plan Notes to the Financial Statements (concluded) For the Years Ended December 31, 2001 and 2000 Master Trust Investment Activities Year Ended December 31 ------------------------------ 2001 2000 ------------- ------------- Investment income: Interest $ 6,356,621 $ 7,917,238 Dividends 1,067,477 934,127 Net change in market value of Nicor Inc. common stock (1,237,633) 7,782,502 Net investment gain from common/collective trusts 767,182 859,623 Net investment loss from registered investment companies (6,654,800) (5,599,494) Demutualization proceeds and other 154,807 - ------------- ------------- 453,654 11,893,996 Administrative expenses (247,141) (273,581) ------------- ------------- Increase in Trust net assets derived from investment activities $ 206,513 $ 11,620,415 ============= ============= Plan's interest in Trust investment activities $ 688,736 $ 6,627,706 ============= ============= 5. INCOME TAXES The Internal Revenue Service has determined and informed the Company by a letter dated January 16, 1997, that the Plan and related Trust, as then designed, was tax exempt under Section 401(a) of the Internal Revenue Code (the Code). The Plan has been amended since receiving the determination letter; however, the Plan's management believes that the Plan and related Master Trust continue to be designed and operated in compliance with the requirements of the Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 18 BIRDSALL, INC. RETIREMENT SAVINGS PLAN FINANCIAL STATEMENTS AS OF DECEMBER 31, 2001 AND 2000 TOGETHER WITH THE REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS 19 REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS To the Birdsall, Inc. Retirement Savings Plan Committee: We have audited the accompanying statement of net assets available for benefits of the Birdsall, Inc. Retirement Savings Plan (the "Plan") as of December 31, 2001, and the related statement of changes in net assets available for benefits for the year then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audit. The financial statements of the Plan for the year ended December 31, 2000 were audited by other auditors whose report, dated June 27, 2001, expressed an unqualified opinion on those statements. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2001, and the changes in net assets available for benefits for the year then ended in conformity with accounting principles generally accepted in the United States of America. Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes as of December 31, 2001 is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This schedule is the responsibility of the Plan's management. Such schedule has been subjected to the auditing procedures applied in our audit of the basic 2001 financial statements and, in our opinion, is fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole.

Retirement Savings Plan Notes to Financial Statements For the Years ended December 31, 2001 and 2000 1. DESCRIPTION OF THE PLAN The following description of the Birdsall, Inc. Retirement Savings Plan provides only general information. Participants should refer to the Plan agreement for more detailed information. The Plan. Birdsall, Inc. (the "Company") established the Tropical Shipping Savings Investment Plan (the "Savings Investment Plan") on September 1, 1983, to provide its eligible employees with an opportunity to accumulate retirement savings. Effective January 1, 1990, the Birdsall, Inc. Profit Sharing Plan was merged into the Savings Investment Plan and re-designated as the Birdsall, Inc. Retirement Savings Plan (the "Plan"). The funds of the Plan are held for safekeeping and investment by the Birdsall, Inc. Retirement Savings Plan Trust (the "Trust"). The Plan is a defined contribution plan and is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Plan administration. Authority to control and manage the operation and administration of the Plan is vested in a committee appointed by the Board of Directors of the Company. On December 1, 2000, the Vanguard Group, Inc. began serving as trustee for the Trust and holds the investments of the Plan under the terms of a trust agreement. The Vanguard Group, Inc. also acts as investment manager for certain investments of the Plan. For the first eleven months of 2000, the Northern Trust Company acted in a similar capacity for the Trust and the investments of the Plan. Administrative expenses associated with the operation of the Plan are paid from Plan assets. Contributions. The participants may elect to make, by payroll deduction, either tax-deferred or after-tax contributions, or any combination thereof that are partially matched by the Company. The Company also pays an annual discretionary profit sharing contribution allocated equally to eligible participants which was $322,119 and $519,318 for the years ended December 31, 2001 and 2000, respectively. In addition, the Plan accepts certain rollovers. Participants direct the investment of their contributions and account balances into various investment options offered by the Plan. Investments. The Plan's investment options currently include the Nicor Company Stock Fund, a Stated Return Fund, and approximately 20 mutual funds. Participant accounts. Individual accounts are maintained for each Plan participant. Each participant's account is increased by the participant's contributions, Company contributions and allocated plan earnings, and decreased by withdrawals, allocated plan investment losses and administrative expenses. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. 24 Birdsall, Inc. Retirement Savings Plan Notes to Financial Statements (continued) For the Years ended December 31, 2001 and 2000 Participant loans. Participants may borrow from their accounts the lesser of $50,000 or 50% of their vested account balance. Loans are repayable through payroll deductions over periods ranging up to 60 months. The interest rate is determined as the prime rate plus 1 percent and is fixed over the term of the loan. Vesting and forfeitures. A participant's contributions and earnings thereon are immediately vested. The Company's contributions and earnings thereon are vested after the participant's completion of five years of service, the participant's death while employed by the Company or retirement. Effective January 1, 2002, a participant is vested in the Company's contributions and earnings thereon upon completion of three years of service. If the participant's interest in the Company's contributions and earnings thereon is not vested, such interest will be forfeited if the participant's employment with the Company or an affiliate is terminated and the participant is not reemployed within five years by the Company or an affiliate. Any amounts forfeited by a participant are applied to reduce the amount of the Company's contributions under the Plan. At December 31, 2001 and 2000, the Plan's assets included forfeited nonvested accounts totaling $103,685 and $233,400, respectively, to be used to reduce future employer contributions. Payment of benefits. On termination of service due to retirement, disability, or death, a participant may elect to receive either a lump-sum amount equal to the participant's vested interest in his or her account balance, or annual installments over a specified period. For termination of service for other reasons, a participant receives the value of the vested interest in his or her account as a lump sum distribution. Suspensions and withdrawals. A participant may suspend contributions and will not cease to be a participant during the suspension period. A participant may elect, under certain conditions, to withdraw participant contributions and earnings thereon prior to termination of employment. The Company's matching contributions and earnings thereon will not be distributed until the vested participant's attainment of age 59-1/2 or employment has been terminated. Plan Termination. The Company expects to continue the Plan indefinitely, but reserves the right to amend or discontinue it at any time subject to the provisions of ERISA. In the event of Plan termination, participants will become fully vested in their account balances. 2. ACCOUNTING POLICIES Basis of accounting. The financial statements of the Plan have been prepared on the accrual basis of accounting. Use of estimates. The preparation of financial statements in accordance with accounting policies generally accepted in the United States of America requires management to make estimates that affect the reported amounts. Actual results could differ from those estimates. 25 Birdsall, Inc. Retirement Savings Plan Notes to Financial Statements (continued) For the Years ended December 31, 2001 and 2000 Investment valuation. The Plan states its investment in the Trust at the underlying value of the investments of the Trust as follows: Group annuity contracts are fully benefit responsive and are recorded at contract value. Contract value represents contributions made plus interest at the various contract rates, less Plan withdrawals and administrative expenses. The aggregate contract value of the group annuity contracts at December 31, 2001 and 2000 approximated fair value. Estimated fair value is based on a variety of factors, such as contract terms, interest rate, maturity date and credit worthiness of the issue. For the years ended December 31, 2001 and 2000, the average yield on the contracts, which equals the average crediting interest rate was 6.6%. There are no reserves against contract value for credit risk of the issuers of contracts or otherwise. The fair value for Nicor, Inc. common stock is based on the closing price on the New York Stock Exchange Composite Tape. The fair value of the units of the common/collective trusts and registered investment companies are determined based on the fair value of the investments of the funds. Market risk. The Plan has investments that generally are exposed to various risks, such as interest rate, credit and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in their values will occur in the near term and such changes could materially affect the amounts reported in the statements of net assets available for benefits. 26 Birdsall, Inc. Retirement Savings Plan Notes to Financial Statements (concluded) For the Years ended December 31, 2001 and 2000 3.

The Plan has been amended since receiving the determination letter; however, the Plan's management believes that the Plan and related Trust continue to be designed and operated in compliance with the requirements of the Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 5. RECONCILIATION OF FINANCIAL STATEMENTS TO FORM 5500 Pending distributions are recorded as a liability in the Plan's Form 5500; however, they are not recognized as liabilities for financial statement purposes.
