Report of Independent Accountants

To the Partners of TransColorado Gas Transmission Company:

In our opinion, the accompanying balance sheets and the related statements of operations, of changes in partners' equity and of cash flows present fairly, in all material respects, the financial position of TransColorado Gas Transmission Company ("the Company") at December 31, 2001 and 2000, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which 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, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

TransColorado Gas Transmission Company

Notes to Financial Statements

1.  DESCRIPTION OF BUSINESS

TransColorado Gas Transmission Company ("TransColorado") is a general partnership formed for the purpose of installing and operating a natural gas transmission system within the states of Colorado and New Mexico. In June 1997, K N TransColorado, Inc. ("K N TransColorado"), a wholly owned subsidiary of Kinder Morgan, Inc. ("KMI"), and Questar TransColorado, Inc. ("QTI"), a wholly owned subsidiary of Questar Pipeline Company, purchased equal portions of the partnership interest in Phase II owned by El Paso Natural Gas Company ("El Paso"). K N TransColorado owns a 50 percent interest in Phase I. QTI purchased the remaining 50 percent interest in Phase I from El Paso. El Paso continued to operate Phase I until December 31, 1998, after which K N TransColorado became the operator.

The Federal Energy Regulatory Commission ("FERC") approved the TransColorado Pipeline which consists of a 295-mile natural gas pipeline and related facilities extending from approximately 30 miles east of Meeker, Colorado to Bloomfield, New Mexico. Gas flowing south through the pipeline moves onto the El Paso and Transwestern pipeline systems. Phase I of the Pipeline, which consists of the southernmost 25 miles, was constructed in 1996 and placed into service on December 13, 1996. Phase I receives gas from three coal seam natural gas treating plants located in the San Juan Basin of Colorado and New Mexico. Phase II of the Pipeline, which consists of the northernmost 270 miles, was constructed during 1998 and 1999 and placed into service on March 31, 1999. Phase II receives gas from pipeline and gathering system interconnections within the Piceance Basin of western Colorado.

TransColorado has a management committee, consisting of one representative from each partner, which establishes major policies. TransColorado's net income (loss) is divided 50 percent to K N TransColorado and 50 percent to Questar TransColorado, based on the partnership agreement.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a)  Basis of Presentation

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from these estimates.

17

(b)  Revenue Recognition

Revenues are recognized in the period the services are provided or products are delivered.

(c)  Accounting for Regulatory Activities

TransColorado is regulated by and subject to the regulations and accounting procedures of the FERC. In addition, TransColorado meets the criteria for application of and, accordingly, follows the accounting and reporting requirements of Statement of Financial Accounting Standards ("SFAS") No. 71, Accounting for the Effects of Certain Types of Regulation for regulated enterprises. Regulatory assets and liabilities represent probable future revenues or expenses to TransColorado associated with certain charges and credits that will be recovered from or refunded to customers through the ratemaking process.

(d)  Property, Plant and Equipment

Property, plant and equipment is stated at historical cost which, for constructed plant, includes indirect costs such as payroll taxes, fringe benefits, and administrative and general costs. Expenditures that increase capacities or extend useful lives are capitalized. Routine maintenance, repairs and renewal costs are expensed as incurred.

In accordance with the provisions of SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of TransColorado reviews the carrying values of its long-lived assets whenever events or changes in circumstances indicate that such carrying values may not be recoverable. As yet, no asset or group of assets have been identified for which the sum of expected future cash flows (undiscounted and without interest charges) is less than the carrying amount of the asset(s) and, accordingly, no impairment losses have been recorded. However, currently unforeseen events and changes in circumstances could require the recognition of impairment losses at some future date. These impairment rules are retained by SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which superceded SFAS No. 121 effective January 1, 2002.

(e)  Depreciation

Depreciation is computed using the straight-line method. Depreciation expense in the income statements for 2001, 2000 and 1999 was computed using annual rates of 3.99 percent.

(f)  Allowance for Funds Used During Construction

Included in the cost of property, plant and equipment is an allowance for funds used during construction ("AFUDC"). AFUDC represents the estimated cost of capital funds during the construction period. AFUDC of approximately $4.6 million was capitalized during 1999 for amounts related to Phase II construction.

18

(g)  Gas Transportation Imbalances

Gas transportation imbalances receivable and payable reflect gas volumes owed to TransColorado from its customers or by TransColorado to its customers and are valued at December average monthly index prices of $2.09 per MMbtu and $4.41 per MMbtu at December 31, 2001 and 2000, respectively. No contracts on TransColorado arose prior to the implementation of FERC Order No. 636. Gas transportation imbalance receivables and payables are equal in total and are offset in the statements of cash flows.

(h)  Income Taxes

Income taxes are the responsibility of the partners and accordingly are not reflected in the financial statements of the partnership.

(i)  Cash Flow Information

TransColorado considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash paid for interest totaled $11.0 million, $13.9 million and $9.8 million in 2001, 2000 and 1999, respectively.

3.  NOTES PAYABLE

In October 1998, TransColorado entered into a $200 million revolving credit agreement (the "Agreement") with a group of banks. Under this Agreement, borrowings were at the London Interbank Offered Rate ("LIBOR") plus 0.475 percent at the date of borrowing. The Agreement expired October 14, 2001. The average interest rate during 2001, 2000 and 1999 was 5.59 percent, 7.21 percent and 6.63 percent, respectively. At December 31, 2000, there was $200 million outstanding under the Agreement. The Agreement was guaranteed by Kinder Morgan, Inc. and Questar Pipeline Company. In October 2001, K N TransColorado and Questar TransColorado, Inc. each contributed $100 million to TransColorado and TransColorado repaid the $200 million outstanding under the Agreement.

4.  FINANCIAL INSTRUMENTS

In January 1999, TransColorado entered into a 2-year interest rate swap agreement covering $100 million of notional principal whereby it paid a fixed rate of 4.95 percent quarterly in arrears; the counter party paid a LIBOR rate quarterly in arrears, which was reset every three months. This agreement was terminated in December 1999 at which time TransColorado received a lump sum pay-out of $1.5 million. The pay-out was amortized over the original term of the agreement. Concurrently with the termination, TransColorado entered into a 13-month interest rate swap agreement covering $100 million of notional principal whereby it paid a fixed rate of 6.28 percent quarterly in arrears; the counter party paid a LIBOR rate quarterly in arrears, which was reset every three months. This agreement was terminated in June 2000 at which time TransColorado received a lump sum pay-out of $0.3 million. The pay-out was amortized over the 13-month term of the agreement.

The estimated fair values of all financial instruments approximate their carrying amounts in the accompanying balance sheet.

19

5.  REGULATORY MATTERS

On October 30, 1998, TransColorado filed a general rate case for rates to become effective the first day of service for Phase II. On December 18, 1998, the FERC issued a suspension order permitting rates to become effective on the in-service date of Phase II facilities subject to certain conditions. By order issued January 14, 2000, the settlement of TransColorado' s rate case in Docket No. RP99- 106 was approved with rates effective March 31, 1999, subject to refund pending the outcome of a cost and revenue report filed on February 1, 2001. The cost and revenue report includes actual accounting and operating data for the period covering March 31, 1999 through September 30, 2000, and provides the basis for final rates, which when approved will be effective retroactive to February 1, 2001. On May 17, 2001, the Administrative Law Judge in the proceeding certified TransColorado's May 3, 2001, "Notice and Request for Certification of Final Rates to the Commission and Motion for Shortened Comment Period."

6.  LITIGATION

"K N TransColorado, Inc. v. Questar Corporation ("Questar"), et. al," Case No. 00-CV-129, District Court, Garfield County, Colorado. On June 15, 2000, K N TransColorado filed suit against Questar TransColorado and several of its affiliated Questar entities, asserting claims for breach of fiduciary duties, breach of contract, constructive trust, rescission of the partnership agreement, breach of good faith and fair dealing, tortious concealment, misrepresentation, aiding and abetting a breach of fiduciary duty, dissolution of the TransColorado partnership, and seeking a declaratory judgment, among other claims. The TransColorado partnership has been made a defendant for purposes of an accounting. The lawsuit stems from Questar's alleged failure to support the TransColorado partnership, together with its decision to seek regulatory approval for a project that competes with the Partnership, in breach of its fiduciary duties as a partner. K N TransColorado seeks to recover damages in excess of $152 million due to Questar's alleged breaches and, in addition, seeks punitive damages. In response to the complaint, on July 28, 2000, the Questar entities filed a counterclaim and third party claims against K N TransColorado and certain of its affiliates alleging breach of fiduciary duty, breach of covenant of good faith and fair dealing, fraud, tortious concealment, negligent misrepresentation, breach of contract and conspiracy. The claims allege, among other things, that the Kinder Morgan entities interfered with and delayed construction of the pipeline and made misrepresentations about marketing of capacity and breached their fiduciary duties as a partner. The Questar entities seek to recover damages in excess of $185 million for an alleged breach of fiduciary duty and other claims. Questar filed a motion to dismiss or stay the matter in deference of the jurisdiction of the Federal Energy Regulatory Commission. The judge denied Questar's motion. On December 15, 2000, the parties agreed to stay the exercise of a contractual provision purportedly requiring K N TransColorado to purchase Questar' s interest in the pipeline and to investigate the appointment of an independent operator for the pipeline during the litigation.

On January 31, 2001, the Court dismissed Questar' s counterclaims for breach of duty of good faith and fair dealing and for indemnity and contribution and dismissed Questar' s Third Party Complaint. On July 19, 2001, the Court granted K N TransColorado' s motion for summary judgment that: a) fiduciary duties existed between the partners; b) these fiduciary duties were not modified or waived; and c) the affiliates and Directors of Questar Pipeline Company and Questar TransColorado acting in their dual capacity had fiduciary obligations which required those individuals to disclose, to the partnership and the partners, information that affected the fundamental business purpose of the partnership. On August 14, 2001, the Court granted leave to Questar to file its First Amended Answer and Counterclaim, once a gain naming Kinder Morgan, Inc. as a counterclaim defendant, and making similar allegations as set forth above. Fact discovery and expert discovery have closed. Trial of the matter commenced on April 1, 2002. See Note 10.

"United States of America, ex rel., Jack J. Grynberg v. TransColorado Gas Transmission Company, et. Al.," Civil Action No. 97-D-1422, filed in the U.S. District Court, District of Colorado. This action was filed pursuant to the federal False Claims Act and involves allegations of mismeasurement of natural gas produced from federal and Indian lands. The Department of Justice has decided not to intervene in support of the action. The complaint is part of a larger series of similar complaints filed by Mr. Grynberg against 77 natural gas pipelines (approximately 330 other defendants). An earlier single action making substantially similar allegations against the pipeline industry was dismissed by Judge Hogan of the U.S. District Court of the District of Columbia on grounds of improper joinder and lack of jurisdiction. As a result, Mr. Grynberg filed individual complaints in various courts throughout the country. These cases were consolidated by the Judicial Panel for Multidistrict Litigation, and transferred to the district of Wyoming. The consolidated action is styled as in "Re: Natural Gas Royalties Qui Tam Litigation," MDL Docket No. 1293. Motions to Dismiss were filed on November 19, 1999. On July 20, 2000 the United States of America filed a motion to dismiss those claims by Grynberg that deal with the manner in which defendants valued gas produced from federal leases.

Judge Downes denied the defendant's motion to dismiss on May 18, 2001. The defendants have requested a status conference.

"Quinque Operating Company, et. al. v. Gas Pipelines, et. al.," Case No. 99-1390-CM, United States District Court for the District of Kansas. This action was originally filed in Kansas State Court in Stevens County, Kansas as a class action against approximately 245 pipeline companies and their affiliates, including TransColorado. The plaintiffs in the case purport to represent a class of natural gas producers and fee royalty owners who allege that they have been subject to systematic gas mismeasurement by the defendants for more than 25 years. Subsequently, one of the defendants removed the action to Kansas Federal District Court. Thereafter, Kinder Morgan, Inc., on behalf of TransColorado, filed a motion with the Judicial Panel for Multidistrict Litigation to consolidate this action for pretrial purposes with the False Claim Act cases referred to above, because of common factual questions. On April 10, 2000, the MDL Panel ordered that this case be consolidated with the False Claims Act cases in the District of Wyoming. On January 12, 2001, the Federal District Court of Wyoming issued an oral ruling remanding the case back to the State Court in Stevens County, Kansas. On April 11, 2001, the Stevens County Court held a case management conference and set a schedule for preliminary motions practice. Personal jurisdiction discovery has commenced. Merits discovery has been stayed. On January 23, 2002, the defendants filed a motion to dismiss on grounds other than personal jurisdiction, and a motion to dismiss for lack of personal jurisdiction for non-resident defendants. TransColorado was recently voluntarily dismissed without prejudice by the Plaintiffs from the Quinque action on the basis that TransColorado does not measure gas at the wellhead for purposes of calculating royalties or for initially determining the volume and heating content of the gas.

TransColorado believes that it has meritorious defenses to all lawsuits and legal proceedings in which it is a defendant and will vigorously defend against them. Based on its evaluation of the above matters, TransColorado believes that the resolution of such matters will not have a material adverse effect on TransColorado's business, cash flows, financial position or results of operations.

8.  MAJOR CUSTOMERS

For the year ended December 31, 2001, revenues from two customers were approximately $4.1 million and $3.6 million, amounts that exceeded 10% of TransColorado' s total revenue. For the year ended December 31, 2000, revenues from three customers were approximately $3.2 million, $1.0 million, and $0.7 million, amounts that exceeded 10% of TransColorado' s total revenue. For the year ended December 31, 1999, revenues from three customers were approximately $3.2 million, $0.7 million and $0.5 million, amounts that exceeded 10% of TransColorado's total revenue.

9.  RECENT ACCOUNTING PRONOUNCEMENT

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." This Statement addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. This Statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. This Statement contains disclosure requirements that provide descriptions of asset retirement obligations and reconciliations of changes in the components of those obligations. This Statement is effective for financial statements issued for fiscal years beginning after June 15, 2002. Earlier applications are encouraged. TransColorado has not yet quantified the impacts of adopting this Statement on its financial position or results of operations.

10.  SUBSEQUENT EVENTS (unaudited)

On October 23, 2002, KMI placed in escrow $105.5 million as the purchase price for the stock of QTI, to purchase its 50% interest in TransColorado Gas Transmission Company. Following the waiting period for the Hart-Scott-Rodino process, QTI withdrew the funds from the escrow account. The date of the withdrawal was November 29, 2002. This settles all outstanding litigation between QTI and KMI relating to TransColorado. Effective November 29, 2002, KMI owns 100% of TransColorado Gas Transmission Company.
