                        Report of Independent Accountants

To the Participants and Administrator of the
Cabot Oil & Gas Corporation Savings Investment Plan


In our opinion, the accompanying statements of net assets available for benefits
and the related statements of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Cabot Oil & Gas Corporation Savings Investment Plan (the Plan) at
December 31, 2001 and 2000, and the changes in net assets available for benefits
for the years then ended in conformity with accounting principles generally
accepted in the United States of America. 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 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.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) 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. The
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

Cabot Oil & Gas Corporation Savings Investment Plan
Notes to Financial Statements
December 31, 2001 and 2000


1.       Description of Plan

         The following brief description of the Cabot Oil & Gas Corporation
         Savings Investment Plan (the Plan) is provided for general information
         purposes only. Participants should refer to the summary plan
         description and legal plan document for more complete information.

         General

         Cabot Oil & Gas Corporation (COGC or Company) was previously a
         subsidiary of Cabot Corporation (Cabot). In February 1990, the Company
         completed its initial public offering of approximately 18% of the total
         outstanding shares of common stock and, accordingly, ceased to be a
         wholly-owned subsidiary of Cabot. On March 28, 1991, Cabot completed an
         exchange offer. Following the completion of the exchange offer, the
         Company became 100% publicly-owned and ceased to be a subsidiary of
         Cabot.

         Effective January 1, 1991, COGC established the Plan, a defined
         contribution plan, in which participation is voluntary on the part of
         the employees. Employees are eligible to become a participant in the
         Plan upon the first day of employment.

         Prior to the commencement of the Plan, COGC employees participated in
         the Cabot Profit Sharing and Savings Plan (PSSP) and the Cabot Employee
         Stock Ownership Plan (ESOP). All COGC employees who were members of the
         PSSP automatically became a participant in the Plan on January 1, 1991,
         were 100% vested with respect to balances in the PSSP and ESOP as of
         December 31, 1990, and had their PSSP and ESOP account balances
         transferred to the Plan. The Plan assumed legal responsibility for the
         accrued benefits of such affected employees on January 1, 1991.

         Benefits under the ESOP were frozen as of December 31, 1990. The ESOP
         balance is comprised of Cabot and/or COGC common stock. Effective
         September 1, 2000, the participant is eligible to withdraw, exchange,
         or take a loan against the ESOP balance. Dividends earned on the ESOP
         common stock are distributed to the other Plan investment election(s)
         according to the participant's most recent investment election. If such
         an election is not made by a participant, dividends from the ESOP are
         placed in the money market fund.

         Contributions

         A participant can contribute in the aggregate from 1% to 15% of
         eligible compensation as defined in the Plan on a pre-tax (before
         federal and state taxes are withheld) and/or after-tax basis through
         payroll deductions, except for employees residing in the state of
         Pennsylvania. Pennsylvania requires that state taxes be withheld before
         the pre-tax contribution. The participant is always fully vested in his
         or her contributions made on either a pre-tax or after-tax basis.

         Effective July 1, 2001, the Company provided an incentive for each
         employee to participate in the pre-tax portion of the Plan by matching
         100% of the first 6% of eligible compensation contributed.

                                      -4-



Cabot Oil & Gas Corporation Savings Investment Plan
Notes to Financial Statements
December 31, 2001 and 2000



         Prior to July 1, 2001, the Company's matching incentive was 100% of the
         first 4% of eligible compensation contributed.

         Vesting

         The participant is credited with a year of vesting service for each
         plan year in which he or she has 1,000 or more hours of service. The
         Company matching contribution vests 20% per year after the first year
         of vesting service, with 100% vesting attained after five years of
         vesting service. Service with Cabot prior to January 1, 1991 counts as
         vesting service under the Plan to the extent and in the same manner as
         computed under the PSSP. A participant's account becomes 100% vested
         with less than five years of vesting service as a result of either (i)
         permanent and total disability, (ii) death (account value is paid to
         the designated beneficiary), or (iii) attainment of age 65. The Plan
         was amended in March 2000 to fully vest certain participants who were
         terminated due to a reduction in workforce. Additionally, the Amendment
         grants service credits to all employees who become employed by the
         Company as a result of an acquisition or merger for purposes of
         eligibility and vesting.

         If a participant leaves COGC and is rehired within five years, the
         prior service with COGC will be restored under the Plan. Additionally,
         if the participant was partially vested when the employment was
         initially terminated, COGC will redeposit any amount of the matching
         contribution which was forfeited from the account (because the
         participant left before becoming 100% vested) after repayment by the
         participant of his or her previous distribution, if any.

         Investment Elections

         The Plan also allows the participants to (i) change the percentage of
         pay withheld through payroll deduction a maximum of four times per
         year, with changes taking effect the first pay period after advance
         notice, (ii) change investment fund options for future contributions at
         any time, directly by telephone with the Fidelity Management Trust
         Company (Trustee) or via internet, (iii) transfer the total balance of
         his or her accumulated investments from one fund to another twelve
         times per year, and (iv) discontinue participation in the Plan at any
         time, to be effective the first pay period after advance notice.
         Re-enrollment can be at any time, except after a hardship withdrawal.

         Payment of Benefits

         A participant eligible for a distribution from the Plan may elect to
         receive an immediate lump sum payment, or if the participant's account
         balance exceeds $5,000 he or she can defer the payment up to age 70.5.

         An exception is made for those participants who (i) had shares of Cabot
         stock transferred from the PSSP and/or ESOP to the Plan and (ii)
         exchanged shares of Cabot common stock in his or her PSSP and/or ESOP
         account for shares of COGC common stock pursuant to an exchange offer
         completed by Cabot in March 1991. Such participants can have the stock
         balance paid in cash or as common stock certificates. If the
         participant decides to sell such stock certificates, the commission fee
         will be reflected in the net asset value of the stock trade. Balances
         transferred to the Plan from the PSSP and/or ESOP retain payment
         options provided under the PSSP and/or ESOP.

         Withdrawals During Employment

         A participant is eligible to make certain withdrawals while employed.
         The first category of funds that are eligible for withdrawal represent
         amounts that were transferred from the PSSP. The second category
         represents amounts contributed under the Plan. Different rules apply to
         the withdrawal depending on the category. If the participant was a
         former member in the PSSP, the participant is eligible to make either a
         voluntary withdrawal or a hardship withdrawal from the amounts that
         were transferred. A voluntary withdrawal may be made from the PSSP
         after-tax and employer contribution accounts. Two voluntary withdrawals
         can be made per year, provided that not more than two are made within
         three months of each other. A voluntary withdrawal will be deducted
         from the participant's account in a specific order as provided for in
         the Plan.

         A participant is also eligible for a hardship withdrawal from his or
         her PSSP pre-tax account under the following conditions, (i) in a year
         in which the participant has already made two voluntary withdrawals and
         (ii) when three months have not elapsed since the time of the last
         voluntary withdrawal. Special rules apply which determine the hierarchy
         of access to the various sources of funds including (i) the participant
         has already withdrawn the full amount of both the after-tax
         contributions and the vested Company contributions, (ii) the
         participant must have fully exhausted the ability to obtain funds from
         any other source, including a loan from the Plan, and (iii) the
         participant submitted an application to the administrative committee
         for a hardship withdrawal. Following a hardship withdrawal, there will
         be an automatic 12-month suspension of the participant's pre-tax
         contributions.

         A participant can withdraw at any time an amount equal to the after-tax
         contributions made to the Plan after January 1, 1991. The minimum
         withdrawal amount is $500. A withdrawal of after-tax contributions
         requires a withdrawal of a proportionate share of investment earnings
         thereon, which will be taxable and will include 10% early distribution
         tax if made before age 59.5 under current tax laws. Additionally, the
         participant can withdraw an amount equal to the pre-tax contributions
         made to the plan after January 1, 1991 at any time after age 59.5. This
         withdrawal will be taxable, but will not include the 10% early
         distribution tax under current tax laws.

         Loans to Participants

         A participant can borrow up to 50% of his or her vested account balance
         (including ESOP) while in the Plan. The amount borrowed may be from a
         minimum of $1,000 to a maximum of $50,000, but never more than 50% of
         the vested account balance. Only one loan can be outstanding at any one
         time. A loan must be repaid by payroll deduction over a period not to
         exceed five years; early payoff is permitted. The loan interest rate is
         set by the administrative committee and, for the 2001 plan year, it was
         1% above the prime rate charged by COGC's principal commercial bank in
         effect at the time of the loan. The set-up fee and the ongoing
         administrative fee for the loan are charged directly to the
         participant's account on a quarterly basis. Loans are limited to
         members who are active employees.

         Withdrawals Upon Termination of Employment

         A participant can withdraw the total vested amount in the Plan account
         as a result of either (i) termination of employment (ii) retirement at
         age 65 or at age 55 or later with 10 years of service or (iii)
         permanent and total disability or death. The full value of the Plan

         account will be paid and will be subject to income tax when the
         participant retires or qualifies as permanently and totally disabled,
         unless an election is made by the participant to rollover the funds as
         allowed by the Internal Revenue Code. If death occurs before
         retirement, the full value of the account will be paid to the
         designated beneficiary. Any portion of an eligible rollover
         distribution can be paid directly to an eligible retirement plan
         specified by the distributee in a direct rollover.

         Disposition of Forfeitures by Participants

         A forfeiture of unvested benefits shall be accounted for in the
         following manner. First, the forfeiture shall be credited to the
         Company contribution account of a re-employed participant for whom a
         reinstatement of prior forfeiture is required. Second, the forfeiture
         shall be applied toward the account of a former participant pursuant to
         the unclaimed benefit provisions of the Plan. To the extent that
         forfeitures for any Plan year exceed the amounts required to reinstate
         the accounts noted above, they will be applied against the next
         succeeding Company contribution.

         For the years ended 2001 and 2000, employer contributions were reduced
         by approximately $31,158 and $38,057, respectively, from forfeited
         nonvested accounts.

         Rollover Contributions

         Generally, if a participant received a qualified total distribution as
         defined in the Internal Revenue Code of 1986 as amended, the
         participant can deposit or rollover those funds into the Plan if
         approved by the Administrative Committee.

         Participant Accounts

         Each participant's account is credited with the employee's
         contribution, the Company contributions and the proportionate
         allocation of the earnings of the Plan, as defined.

         Plan Trustee

         Fidelity Management Trust Company was appointed trustee of the Plan by
         a contract dated June 1, 1991. Under the contract, the trustee shall
         hold all property received, manage the Plan and invest and reinvest
         Plan assets.

2.       Summary of Significant Accounting Policies

         Basis of Presentation

         The accompanying financial statements have been prepared on the accrual
         basis of accounting in accordance with accounting principles generally
         accepted in the United States of America.

         Use of Estimates

         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 that affect the reported
         amounts of net assets available for benefits at the date of the
         financial statements and the reported amounts of changes in net assets
         available for benefits during the reporting period. Actual results
         could differ from those estimates.

         Valuation of Investments

         Investments are recorded at fair market value based on market prices
         that have been provided by the Trustee.

         Net (Depreciation)/Appreciation in Fair Market Value of Investments

         The statement of changes in net assets available for Plan benefits
         presents the net (depreciation)/appreciation in the fair market value
         of investments which consists of realized gains or losses and the
         unrealized (depreciation)/appreciation on those investments.

         Administrative Expenses

         Administrative expenses consist of all expenses incident to the
         administration, termination or protection of the Plan, including, but
         not limited to, legal, accounting, investment manager and trustee fees.
         Substantially all administrative expenses, except for expenses
         associated with loans to participants, were paid by the Company in
         2001.

         Risks and Uncertainties

         The Plan provides for various investment options in any combination of
         stocks and mutual funds. Investment securities are exposed to various
         risks, such as market and credit risk. Due to the level of risk
         associated with certain investment securities, it is at least
         reasonably possible that changes in the values of investment securities
         will occur in the near term and that such changes could materially
         affect the amounts reported in the statement of net assets available
         for benefits.

3.       Investments

         The following presents investments that represent five percent or more
         of the Plan's net assets as of December 31, 2001 and 2000 at their
         current value.

4.       Plan Termination

         While the Company has not expressed any intent to discontinue its
         contributions or terminate the Plan, it may do so at any time. In the
         event of such a discontinuance or termination of the Plan, all amounts
         credited to the accounts of participants shall become fully vested and
         non-forfeitable.

5.       Tax Status of Plan

         The Plan is designed to constitute a "Qualified Plan" under the
         provisions of Section 401(a) of the Internal Revenue Code and,
         therefore, be exempt from federal income tax under the provisions of
         Section 501(a). The Plan obtained its latest determination letter on
         October 23, 1993, in which the Internal Revenue Service stated that the
         Plan was in compliance with the applicable requirements of the Internal
         Revenue Code. The Plan was amended in 1994, 1998, 1999, 2000 and 2001,
         subsequent to the receipt of the determination letter. The Plan has a
         pending request for a new determination letter, which was filed on
         February 27, 2002. The Plan Administrator believes the Plan is
         currently designed and being operated in compliance with the applicable
         requirements of the Internal Revenue Code. Therefore, no provision for
         income taxes has been included in the Plan's financial statements.

6.       Party-in-Interest Transactions

         The Plan invests in various Fidelity mutual funds and portfolios. These
         investments are considered party-in-interest transactions because
         Fidelity Management Trust Company serves as trustee of the Plan. The
         Plan management has approved these investment options.

         The Plan also invests in COGC common stock. Transactions in Company
         stock are considered party-in-interest transactions because COGC is the
         Plan sponsor.
