2005 Form of Non-Employee Director Restricted Stock Unit Award Agreement

 Exhibit 10.1 
  
 CABOT OIL & GAS CORPORATION 
 2004 INCENTIVE PLAN 
  
 NON-EMPLOYEE DIRECTOR RESTRICTED STOCK UNIT AWARD AGREEMENT 
  
 THIS AGREEMENT (“Agreement”), made as of May 24, 2005 (the “Grant Date”), evidences an award by CABOT OIL & GAS CORPORATION, a Delaware corporation (the “Company”), to
                             (the “Grantee”), a nonemployee director of the Company,
pursuant to the Cabot Oil & Gas Corporation 2004 Incentive Plan (the ”Plan”). Capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Plan. 
  
 1. Grant of Restricted Stock Units. Effective as of the Grant Date,
pursuant to Paragraph 8(a)(ii) of the Plan, the Company has awarded to the Grantee Restricted Stock Units representing a total of 1,950 shares of Common Stock, subject to the conditions and restrictions set forth below and in the Plan (the
“Restricted Stock Units”). 
  
 2. Restrictions.
The Restricted Stock Units granted hereunder to the Grantee may not be sold, assigned, transferred, pledged or otherwise encumbered from the Grant Date unless and until the date that the Grantee obtains the rights of a Stockholder as described
in Section 9 of this Agreement. The Grantee shall have a vested right to all of the Restricted Stock Units as of the Grant Date; provided, however, that Common Stock to which such Restricted Stock Units relate shall not be deliverable
to the Grantee until the date that the Grantee ceases to be a director of the Board of Directors of the Company. 
  
 3. Dividend Credits. During the period of time between the Grant Date and the date on which Grantee receives a distribution of the shares of Common
Stock related to the Restricted Stock Units awarded hereunder, the Award of Restricted Stock Units hereunder shall be evidenced by book entry registration. As of each date that dividends are paid with respect to Common Stock, the Grantee shall have
an amount credited to his account equal to the amount of the dividend paid per share of Common Stock as of such dividend payment date multiplied by the number of Restricted Stock Units credited to the Grantee’s account immediately prior to such
dividend payment date, with such amount to be payable to the Grantee on the earlier of (i) the date of which the Grantee receives his or her next quarterly payment of the annual retainer paid to Grantee for service as a director of the Board of
Directors of the Company, or (ii) the date that the Grantee no longer serves as a director of the Company. 
  
 4. Beneficiary Designations. The Grantee shall file with the Secretary of the Company on such form as may be prescribed by the Company, a
designation of one or more beneficiaries and, if desired, one or more contingent beneficiaries (each referred to herein as a “Beneficiary”) to whom shares of Common Stock otherwise due the Grantee under the terms of this Agreement shall be
distributed in the event of the death of the Grantee. The Grantee shall have the right to change the Beneficiary or Beneficiaries from time to time; provided, however, that any change shall not become effective until received in
writing by the Secretary of the 
  

 -1- 

 Company. If any designated Beneficiary survives the Grantee but dies after the Grantee’s death, any remaining
benefits due such deceased Beneficiary under this Agreement shall be distributed to the personal representative or executor of the deceased Beneficiary’s estate. If there is no effective Beneficiary designation on file at the time of the
Grantee’s death, or if the designated Beneficiary or Beneficiaries have all predeceased such Grantee, the payment of any remaining benefits under this Agreement shall be made to the personal representative or executor of the Grantee’s
estate. If one or more but not all the Beneficiaries have predeceased such Grantee, the benefits under this Agreement shall be paid according to the Grantee’s instructions in his designation of Beneficiaries. If the Grantee has not given
instructions, or if the instructions are not clear, the benefits under this Agreement which would have been paid to the deceased Beneficiary or Beneficiaries will be paid to the personal representative or executor of Grantee’s estate. 

  
 5. Nonalienation of Benefits. Except as contemplated by
Section 4 above, no right or benefit under this Agreement shall be subject to transfer, anticipation, alienation, sale, assignment, pledge, encumbrance or charge, whether voluntary, involuntary or by operation of law, and any attempt to transfer,
anticipate, alienate, sell, assign, pledge, encumber or charge the same shall be void. No right or benefit hereunder shall in any manner be liable for or subject to any debts, contracts, liabilities or torts of the person entitled to such benefits.
If the Grantee or the Grantee’s Beneficiary hereunder shall become bankrupt or attempt to transfer, anticipate, alienate, assign, sell, pledge, encumber or charge any right or benefit hereunder, other than as contemplated by Section 4 above, or
if any creditor shall attempt to subject the same to a writ of garnishment, attachment, execution, sequestration or any other form of process or involuntary lien or seizure, then such right or benefit shall cease and terminate. 
  
 6. Prerequisites to Benefits. Neither the Grantee, nor any person
claiming through the Grantee, shall have any right or interest in Restricted Stock Units awarded hereunder or the shares of Common Stock related thereto, unless and until all the terms, conditions and provisions of this Agreement and the Plan which
affect the Grantee or such other person shall have been complied with as specified herein. 
  
 7. Payment. Upon satisfaction of all the terms, conditions and provisions of this Agreement and the Plan, a Restricted Stock Unit credited to the Grantee’s account shall be payable to the Grantee in the
form of one share of Common Stock. 
  
 8. Restrictions on
Delivery of Shares. The Company shall not be obligated to deliver any shares of Common Stock if counsel to the Company determines that such issuance or delivery would violate any applicable law or any rule or regulation of any governmental
authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Common Stock is listed or quoted. If necessary to comply with any such law, rule, regulation or agreement, the Company
shall in no event be obligated to take any affirmative action in order to cause the delivery of shares of Common Stock. 
  
 9. Rights as a Stockholder. The Grantee (or Beneficiary) shall have no rights as a stockholder with respect to the shares of Common Stock
represented by the Restricted Stock Units unless and until all the terms, conditions and provisions of this Agreement and the 
  

 -2- 

 Plan which affect the Grantee or such other person shall have been complied with as specified herein, and certificates
evidencing such shares are delivered to the Grantee pursuant to Section 7 hereof. 
  
 10. Adjustments. As provided in Paragraph 15 (Adjustments) of the Plan, certain adjustments may be made to the Restricted Stock Units upon the occurrence of events or circumstances described in Paragraph 15 of
the Plan.

 As provided in and pursuant to Section 303 of the Original Indenture, each time that the Company delivers Notes to the Trustee or Authenticating Agent for
authentication after the initial issuance of Notes under this Indenture, the Company shall deliver a Supplemental Company Order in the form of Exhibit C to this Tenth Supplemental Indenture (which form shall be completed upon delivery with
the series designation applicable to the Notes) for the authentication and delivery of such Notes and the Trustee or such Authenticating Agent shall authenticate and deliver such Notes.

transferor shall deliver a letter from the transferee to the Company and the Trustee, as the case may be, which shall provide, among other things, that the transferee is an Institutional Accredited Investor and that it is acquiring the Initial Notes
for investment purposes and not for distribution in violation of the Securities Act.

 (vi) The purchaser acknowledges that the Trustee will not be required to accept for registration of transfer
any Initial Notes acquired by it, except upon presentation of evidence satisfactory to the Company and the Trustee that the restrictions set forth herein have been complied with.

asset manager within the meaning of Part IV(a) of Prohibited Transaction Class Exemption 96-23, such manager has made or properly authorized the decision for such plan to purchase Notes, under circumstances such that Prohibited Transaction Class
Exemption 96-23 is applicable and satisfied with respect to the purchase and holding of such Notes; or 
  
 (vii) to the extent such purchase will not otherwise give rise to a transaction described in Section 406 of ERISA or Section 4975(c)(1) of
the Code for which a statutory or administrative exemption is unavailable.

 (REVERSE OF NOTE) 
  
 TECO ENERGY, INC. 
  
 6.75% Notes Due 2015 
  
 This Note is one of a duly authorized series of securities of the Company (herein called the “Notes”), issued and to be issued under an
Indenture dated as of August 17, 1998, as supplemented by the Tenth Supplemental Indenture, dated as of May 26, 2005 (as such has been or shall be amended or supplemented, the “Indenture”), between the Company and The Bank of New
York, as trustee (the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the securities of the series designated on the face hereof. 
  
 DEFINITIONS 
  
 The following terms, as used herein, have the following meanings unless the
context or use clearly indicates another or different meaning or intent: 
  
 “Business Day” shall mean any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or obligated by law or executive order to close
in the City of New York. 
  
 “Comparable Treasury
Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and in accordance
with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes; provided, however, that if the remaining term of the Notes to be redeemed is less than one year,
the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. 
  
 “Comparable Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for the Redemption Date, after excluding
the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
  
 “Depositary” shall mean The Depository Trust Company or any
successor depositary. 
  
 “Independent Investment
Banker” means any of UBS Securities LLC, Citigroup Global Markets, Inc. or Morgan Stanley & Co. Incorporated or any of their respective successors, as designated by the Company, or if all of those firms are unwilling or unable to serve
as such, an independent investment and banking institution of national standing appointed by the Company. 
  
 “Interest Payment Date” shall mean May 1 and November 1 of each year. 

 “Reference Treasury Dealer” means: 
  
 (i) UBS Securities LLC, Citigroup Global Markets, Inc. and Morgan Stanley
& Co. Incorporated, and each of their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will
substitute another Primary Treasury Dealer; and 
  
 (ii) up to two
other Primary Treasury Dealers selected by the Company 
  
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by an Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

 
 “Treasury Rate” means, as of any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second business day immediately preceding that redemption date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed
as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date. 
  
 INTEREST RATE 
  
 This Note will bear interest at the rate per annum (computed based on a 360-day year consisting of twelve 30-day months) identified on the face of this Note. Except for the effect of any adjustment in the Interest
Payment Date as provided in the following sentence, the amount of interest payable for any period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a
180-day period. If any Interest Payment Date would otherwise be a day that is not a Business Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on
such payment for the period from and after such Interest Payment Date to the date of such payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the
immediately preceding Business Day, in each case with the same force and effect as if made on such Interest Payment Date. 
  
 OPTIONAL REDEMPTION 
  
 The Notes are subject to redemption, in whole or in part, at any time, and at the option of the Company, at a redemption price equal to the greater of:

  

	 	(i)	100% of the principal amount of the Notes then outstanding to be redeemed, or 

  

	 	(ii)	the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then outstanding to be redeemed (not including any portion of such payments
of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (computed based on a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 50 basis points (0.50%), as calculated by an
Independent Investment Banker, 

 plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date (the “Redemption
Price”). 
  
 The Company will mail a notice of redemption
at least 30 days but no more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be redeemed.

  
 Unless the Company defaults in payment of the Redemption
Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption. 
  
 The Notes are not entitled to the benefit of any sinking fund or analogous provision. 
  
 TRANSFER OR EXCHANGE 
  
 As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registerable in the Security
Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Note are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
  
 The Notes are issuable only in registered form without coupons and, except for such Notes issued in book-entry form, only in denominations of $1,000 and
any integral multiple of $1,000. As provided in the Indenture and subject to certain limitations herein and therein set forth, this Note is exchangeable for a like aggregate principal amount of Notes of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same. 
  
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

  
 Prior to due presentment of this Note for registration of
transfer, the Company or the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary. 
  
 OTHER PROVISIONS 
  
 The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in principal amount of 

 
the Securities at the time Outstanding of each series to be affected and of the Holders of 66 2/3% in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders
of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. To the extent permitted by law, any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
  
 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 
  
 All terms used in this Note that are defined in the Indenture shall have the
meanings assigned to them in the Indenture. 
  
 This Note shall be
governed by and construed in accordance with the laws of The State of New York.
