 INTRODUCTION AND PURPOSE 
  

	1.01  	Purpose of Plan 

 The United Technologies
Corporation Board of Directors Deferred Stock Unit Plan (the “Plan”) has been established to provide an arrangement for non-employee directors to defer their Annual Retainer and Restricted Stock Unit Award for A New Director in the form of
deferred stock units equal in value to shares of the Corporation’s common stock for the purpose of aligning the interests of non-employee directors with those of the Corporation’s shareowners. The Plan is hereby amended and restated for
the purposes of: (i) accommodating changes to the non-employee directors compensation program, including the consolidation of prior compensation program elements into a revised retainer structure as integrated into this Plan; and
(ii) effecting certain changes related to compliance with Section 409A of the Internal Revenue Code. 
  

	1.02  	Effective Date of Plan 

 Changes related to the
re-design of the non-employee directors’ compensation program are generally effective for deferrals credited on and after January 1, 2006. Changes related to Section 409A of the Internal Revenue Code are generally effective for
deferrals that were earned or vested after December 31, 2004. Amounts that were earned or vested (within the meaning of Section 409A) prior to January 1, 2005, and any subsequent increases in these amounts that are permitted to be
treated as grandfathered benefits under Section 409A, are generally subject to and shall continue to be governed by the terms of the Prior Plan set forth in Appendix A.

capitalized form in the Plan, shall have the meanings set forth below: 
 Account means a bookkeeping account established for a
Participant under Article IV that is credited with Deferred Stock Units representing compensation earned or vested after 2004. Any compensation earned and vested before 2005 shall be credited to a Participant’s Prior Plan Account and shall be

 Annual Retainer means the annual retainer payable to a Participant under
Section 3.01 for services to the Company as a non-employee member of the Board.

 Board means the Board of Directors of the Corporation. 
 Code means the Internal Revenue Code of 1986, as amended from time to time, and any successor thereto. References to any section of the
Internal Revenue Code shall include any final regulations or other published guidance interpreting that section.

Section 3.02 upon election to the Board. 
  

 3 

 Separation from Service means a Participant’s resignation, removal, or retirement from
the Board (for a reason other than death) that constitutes a good-faith, complete termination of the Participant’s relationship with the Corporation, and that also qualifies as a “separation from service” for purposes of

 ARTICLE III 
 ELIGIBLE COMPENSATION

  

	3.01  	Annual Retainer 

 (a) Annual Retainer Amount.
Effective January 1, 2006, subject to subsections (b) and (c) of this Section 3.01, the Annual Retainer shall be as follows: in the case of the Audit Committee Chair and the Presiding or Lead Director, $260,000; in the case of
any other member of the Audit Committee, $250,000; in the case of any other Committee Chair, $230,000; and for all other Participants, $220,000. The Annual Retainer is subject to change from time to time at the discretion of the Committee.

 (b) Terminated Participants. If a Participant’s Separation from Service or death occurs before the Corporation’s Annual
Meeting, the Participant will not receive an Annual Retainer for the year of the Participant’s Separation from Service or death. 
 (c)
New Participants. If a Participant is elected to the Board before September 30 of a calendar year, the Participant will receive the full amount of the then applicable Annual Retainer, with 60% of such amount credited automatically to a
Participant’s Annual Retainer Account as Deferred Stock Units as of the date of the Participant’s election to the Board; and with 40% of such amount eligible for a deferral election in accordance with Article V. If a Participant is elected
to the Board after September 30 of a calendar year, the Participant will receive 50% of the then applicable Annual Retainer, with 60% of such amount credited automatically to a Participant’s Annual Retainer Account as Deferred Stock Units
as of the date of the Participant’s election to the Board; and with 40% of such amount eligible for a deferral election in accordance with Article V. 
  

 4 

	3.02  	Restricted Stock Unit Award for a New Director 

 Effective as of the date of the Participant’s election to the Board, the Participant shall receive an unvested Restricted Stock Unit Award for a New Director (“RSU Award”) of Deferred Stock Units equal in value to $100,000 as
of such date. The amount of an RSU Award is subject to change at the discretion of the Committee. 
 ARTICLE IV 
 ACCOUNTS AND CREDITS 
  

	4.01  	Non-elective Annual Retainer 

 60% of the Annual
Retainer shall be credited automatically to a Participant’s Annual Retainer Account as Deferred Stock Units, effective as of the date of the Corporation’s Annual Meeting. Participants may not elect to receive this portion of the Annual
Retainer as current cash. 
  

	4.02  	Elective Annual Retainer 

 40% of the Annual
Retainer is payable in cash unless the Participant makes a timely irrevocable election in accordance with Article V to defer the receipt of this 40% amount as Deferred Stock Units under this Plan in lieu of a cash payment. 
  

	4.03  	Restricted Stock Unit Award for a New Director 

 Effective as of the date of the Participant’s election to the Board, the Corporation will credit the amount of the RSU Award to a New Director Restricted Stock Unit Account (“RSU Account”) established for the Participant. The
amount of an RSU Award is subject to change at the discretion of the Committee. The RSU Account may not be distributed prior to the Participant’s Separation from Service. The value of the RSU Account is subject to forfeiture if Separation from
Service occurs before the first annual meeting following the date of election to the Board. Thereafter, the percentage of such Award subject to forfeiture will be reduced by 20 

  

 5 

 
percentage points as of the date of each succeeding annual meeting until the fifth annual meeting when 100% of the value of such Award will be vested and
subject to distribution following Separation from Service. There will be no forfeiture of interest in the RSU Account in the event of the Participant’s death, Disability, or a “Change in Control” as defined in the Corporation’s
Long Term Incentive Plan while the Participant is a member of the Board, or in the event of the Participant’s resignation or retirement from the Board for the purpose of accepting full-time employment in public or charitable service. A
Participant’s RSU Account will be credited with dividend equivalents which will vest immediately, but will otherwise be subject to the same transfer restrictions applicable to the Deferred Stock Units credited to the Account. 
  

	4.04  	Accounts 

 (a) Post-December 31, 2004
Credits. All Annual Retainer deferrals and RSU Awards earned or vested after December 31, 2004, shall be maintained in Accounts under and shall be subject to the terms and conditions of the Plan, as amended and restated herein, effective
January 1, 2005. Separate Accounts for post-December 31, 2004 Deferred Stock Units will be maintained for each Participant. Sub-accounts may be maintained within Participants’ Accounts to the extent the Committee determines such an
arrangement to be necessary or useful in the administration of the Plan. 
 (b) Pre-January 1, 2005 Credits. All Annual Retainer
deferrals and RSU Awards earned and vested prior to January 1, 2005, and any subsequent increases in these amounts that are permitted to be treated as grandfathered benefits under Section 409A of the Code (e.g., increases in unit value and
dividend equivalents), shall be maintained in separate Prior Plan Accounts and shall remain subject to the terms and conditions of the Prior Plan as in effect on October 3, 2004. Prior Plan Accounts shall be equal to the value earned and vested
on December 31, 2004, as subsequently adjusted in accordance with the Prior Plan. The Prior Plan and Prior Plan Accounts are not intended to be subject to Section 409A of the Code. No amendment to Appendix A that would constitute a
“material modification” for purposes of Section 409A shall be effective unless the amending instrument states that it is intended to materially modify Appendix A and to cause the Prior Plan to become subject to Section 409A.

  

 6 

	4.05  	Deferred Stock Units 

 (a) Deemed Investment in
UTC Common Stock. Except as provided in Section 5.07, a Participant’s Account shall be treated as if it were invested in Deferred Stock Units that are equivalent in value to the fair market value of shares of UTC Common Stock in
accordance with the following rules: 
 (1) Conversion into Deferred Stock Units. The RSU Award credited to a
Participant’s RSU Account under Section 4.03, and the Annual Retainer credited to a Participant’s Annual Retainer Account for a Plan Year under Section 4.01 or 4.02 shall be converted into Deferred Stock Units (including
fractional Deferred Stock Units) by dividing the amount of the RSU Award or Annual Retainer credited by the Closing Price on the date of the Corporation’s Annual Meeting or the date a Participant is elected to the Board, as applicable.

 (2) Deemed Reinvestment Of Dividends. The number of Deferred Stock Units credited to a Participant’s Annual
Retainer or RSU Account on a dividend payment date shall be increased on each date on which a dividend is paid on UTC Common Stock. The number of additional Deferred Stock Units credited to a Participant’s Annual Retainer or RSU Account as a
result of such dividend payment shall be determined by (i) multiplying the total number of Deferred Stock Units (including fractional Deferred Stock Units) credited to the Participant’s Account on the dividend payment date by the amount of
the dividend paid per share of UTC Common Stock on the dividend payment date, and (ii) dividing the product so determined by the Closing Price on the dividend payment date. 
 (3) Conversion Out of Deferred Stock Units. The dollar value of the Deferred Stock Units credited to a Participant’s Annual
Retainer or RSU Account on any date shall be determined by multiplying the number of Deferred Stock Units (including fractional Deferred Stock Units) credited to the Participant’s Account by the Closing Price on that date. 
  

 7 

 (4) Effect of Recapitalization. In the event of a transaction or event described
in this paragraph (4) (a “Recapitalization Event”), the number of Stock Units credited to a Participant’s Annual Retainer or RSU Account shall be adjusted in the same manner as outstanding shares of Common Stock. A
Recapitalization Event includes a dividend (other than regular quarterly dividends) or other extraordinary distribution to holders of Common Stock (whether in the form of cash, shares, other securities, or other property), extraordinary cash
dividend, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, repurchase, or exchange of shares or other securities, the issuance or exercisability of stock purchase rights, the issuance of
warrants or other rights to purchase shares or other securities, or other similar corporate transaction or event that has a material affect on the shares of UTC Common Stock and requires conforming adjustment to the value and/or number of Deferred
Stock Units to prevent dilution or enlargement of the value of Participants’ Accounts. 
  

	4.06  	Hypothetical Nature of Accounts and Investments 

 Each Account established under this Article IV shall be maintained for bookkeeping purposes only. Neither the Plan nor any of the Accounts established under the Plan shall hold any actual funds or assets. The Deferred Stock Units
established hereunder shall be used solely to determine the amounts to be paid hereunder, shall not be or represent an equity security of the Company, shall not be convertible into or otherwise entitle a Participant to acquire an equity security of
the Company and shall not carry any voting or dividend rights. 
 ARTICLE V 
 ELECTION PROCEDURES AND PAYMENTS 
  

	5.01  	Annual Retainer Deferral Election 

 Participants who
elect to defer the receipt of the eligible 40% of each year’s Annual Retainer as Deferred Stock Units under this Plan, must, on or before the election deadline established by the Committee, make a written deferral election on the Election form
provided by the Committee. 
  

 8 

	5.02  	Annual Retainer Deferral Election Deadline 

 A
written Election form must be completed and submitted to the Office of the Corporate Secretary no later than December 31st of the calendar year prior to the year for which the Annual Retainer is earned or, for new Participants, prior to the
date the Participant is elected to the Board, and in no event later than 30 days after such election. If a Participant fails to timely submit a properly completed Election form, the remaining 40% of the Participant’s Annual Retainer earned in
the applicable year shall be paid as provided in Section 4.02. The Participant’s deferral election shall be irrevocable following the election deadline. 
  

	5.03  	Entitlement to Payment 

 Any payment from an Account
under the Plan shall be made solely in cash and as further provided in this Article V. The right of any person to receive one or more payments under the Plan shall be an unsecured claim against the general assets of the Corporation. 
  

	5.04  	Payment Commencement Date 

 Payments to a
Participant with respect to the Participant’s Annual Retainer Account or RSU Account shall begin as of the Participant’s Payment Commencement Date or, if the Participant has changed his payment election as provided in Section 5.06, on
the fifth anniversary of the Participant’s Payment Commencement Date. If a Participant dies before payments to the Participant commence, payment of the entire value of the Participant’s Accounts shall be made in a lump sum to the
Participant’s Beneficiary on the first business day of the third month following the month of the Participant’s death. 
 For
purposes of the Code, a payment is treated as being made on the date when it is due under the Plan if the payment is made on the due date specified by the Plan, or on a later date that is either (a) in the same calendar year (for a payment
whose specified due date is on or before September 30), or (b) by the 15th day of the third calendar month following the date specified by the Plan (for a payment whose specified due date is on or after October 1). A payment also is
treated as being made on the date when it is due under the Plan if the payment is made not more than 30 days before the due date specified by the Plan. A Participant may not, directly or indirectly, designate the taxable year of a payment made in
reliance on the administrative rules in this Section 5.04. 
  

 9 

	5.05  	Election of Form and Amount of Payment 

 (a) Lump
Sum Payment. A Participant shall receive his or her Annual Retainer Account or RSU Account under the Plan as a lump sum payment unless the Participant timely elects to receive his or her Account in the form of 10 annual installments or in 15
annual installments in accordance with subsection (b), below. The lump sum shall be payable to the Participant in cash as of the Payment Commencement Date and shall equal the value of the Deferred Stock Units credited to the Participant’s
Account, determined as of the Payment Commencement Date as provided in Section 5.04. 
 (b) 10 or 15 Annual Installments. A
Participant may elect to receive his or her Annual Retainer Account or RSU Account under the Plan in 10 or 15 installment payments in lieu of the lump sum payment determined under subsection (a), above. Annual installments shall be payable to the
Participant in cash beginning as of the Payment Commencement Date and continuing as of each Payment Anniversary Date thereafter until all installments have been paid. The first annual installment shall equal one-tenth (1/10) (if Participant
elects 10 installment payments) or one-fifteenth (1/15th) (if Participant elects 15 installment payments) of the value of the Participant’s Account, determined as of the Payment Commencement Date. Each successive annual installment shall
equal the value of the Participant’s Account, determined as of the Payment Anniversary Date, multiplied by a fraction, the numerator of which is one, and the denominator of which shall be the number of scheduled annual installments that remain
unpaid. If the Participant dies after the Participant’s Payment Commencement Date but before all installments have been paid, the entire remaining value of the Participant’s Account shall be made in a lump sum to the Participant’s
Beneficiary on the first business day of the third month following the month of the Participant’s death. 
 (c) Form of Payment
Election. A valid payment election for an Annual Retainer Account under subsection (b) shall be made in writing on an Election form, completed and submitted to the Office of the Corporate Secretary no later than December 31st of the
calendar year prior to the year for which the Annual Retainer is earned, or for new Participants, prior to 

  

 10 

 
the date Participant is elected to the Board, and in no event later than 30 days after such election. A valid payment election for an RSU Account under
subsection (b) shall be made in writing on an Election form, completed and submitted to the Office of the Corporate Secretary prior to the date Participant is elected to the Board, and in no event later than 30 days after such election. If a
Participant does not make a valid payment election, the Participant shall be deemed to have elected to receive his or her Annual Retainer Account or RSU Account in a lump sum payment as provided in subsection (a). Except as provided below in
Section 5.06 (Change in Payment Election), a Participant’s payment election shall become irrevocable on the election deadline date. 
  

	5.06  	Change in Payment Election 

 A Participant may make
a one-time irrevocable election to change the form of payment that the Participant elected under Section 5.05. A change to the form of payment must meet the following requirements: 
  

	 	i.	The new election must be made at least twelve months prior to the Payment Commencement Date (and the new election shall be ineffective if the Payment Commencement Date occurs within
twelve months after the date of the new election); 

  

	 	ii.	The new election will not take effect until twelve months after the date when the Participant submits a new Election form to the Office of the Corporate Secretary;

  

	 	iii.	The new payment commencement date must be five years later than the date on which payments would otherwise have commenced; and 

  

	 	iv.	The new form of payment must be one of the forms of payment provided under Section 5.05(a) or (b). 

  

 11 

	5.07  	Investment of Account during Installment Period 

 Participants electing to convert Deferred Stock Units in the Annual Retainer Account or RSU Account to a fixed interest investment for the installment payment period, must, prior to the Payment Commencement Date or subsequent Payment
Anniversary Date, make a written election on the Election form provided by the Committee. If a Participant makes such election to have his or her Account treated as if the Account were invested in cash, the Account will be credited with a rate of
interest equal to the average interest rate on 10-Year Treasury Bonds as of the January through October Period in the calendar year prior to the Plan Year in which the interest is credited, plus 1%. 
 ARTICLE VI 
 ADMINISTRATION 

  

	6.01  	In General 

 The Committee shall have the
discretionary authority to interpret the Plan and to decide any and all matters arising under the Plan, including without limitation the right to determine eligibility for participation, benefits, and other rights under the Plan; the right to
determine whether any election or notice requirement or other administrative procedure under the Plan has been adequately observed; the right to determine the proper recipient of any distribution under the Plan; the right to remedy possible
ambiguities, inconsistencies, or omissions by general rule or particular decision; and the right otherwise to interpret the Plan in accordance with its terms. Except as otherwise provided in Section 6.04, the Committee’s determination on
any and all questions arising out of the interpretation or administration of the Plan shall be final, conclusive, and binding on all parties. 
  

	6.02  	Plan Amendment and Termination 

 (a) The Committee
may amend, suspend, or terminate the Plan at any time; provided that no amendment, suspension, or termination of the Plan shall, without a Participant’s consent, reduce the Participant’s benefits accrued under the Plan before the date of
such amendment, suspension, or termination. 
 (b) In the event of suspension of the Plan, no additional deferrals shall be made under the
Plan, but all previous deferrals shall accumulate and be distributed in accordance with the otherwise applicable provisions of the Plan and the applicable elections on file. 
  

 12 

 (c) Upon the termination of the Plan with respect to all Participants, and termination of all
arrangements sponsored by the Corporation or its affiliates that would be aggregated with the Plan under Section 409A of the Code, the Corporation shall have the right, in its sole discretion, and notwithstanding any elections made by the
Participant, to pay the Participant’s vested Account in a lump sum, to the extent permitted under Section 409A. All payments that may be made pursuant to this Section 6.02(c) shall be made no earlier than the thirteenth month and no
later than the twenty-fourth month after the termination of the Plan. The Corporation may not accelerate payments pursuant to this Section 6.02(c) if the termination of the Plan is proximate to a downturn in the Corporation’s financial
health within the meaning of Treas. Reg. Section 1.409A-3(j)(4)(ix)(C)(1). If the Corporation exercises its discretion to accelerate payments under this Section 6.02(c), it shall not adopt any new arrangement that would have been
aggregated with the Plan under Section 409A within three years following the date of the Plan’s termination. 
  

	6.03  	Reports to Participants 

 The Committee shall
furnish an annual statement to each Participant reporting the value of the Participant’s Account as of the end of the most recent Plan Year. 
  

	6.04  	Delegation of Authority 

 The Committee may delegate
to officers of the Corporation any and all authority with which it is vested under the Plan, and the Committee may allocate its responsibilities under the Plan among its members. 
  

 13 

 ARTICLE VII 
 MISCELLANEOUS 
  

	7.01  	Rights Not Assignable 

 No payment due under the
Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge in any other way. Any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge such payment in
any other way shall be void. No such payment or interest therein shall be liable for or subject to the debts, contracts, liabilities, or torts of any Participant or Beneficiary. If any Participant or Beneficiary becomes bankrupt or attempts to
anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge in any other way any payment under the Plan, the Committee may direct that such payment be suspended and that all future payments to which such Participant or Beneficiary
otherwise would be entitled be held and applied for the benefit of such person, the person’s children or other dependents, or any of them, in such manner and in such proportions as the Committee may deem proper. 
  

	7.02  	Certain Rights Reserved 

 Nothing in the Plan shall
confer upon any person the right to continue to serve as a member of the Board or to participate in the Plan other than in accordance with its terms. 
  

	7.03  	Withholding Taxes 

 The Committee may make any
appropriate arrangements to deduct from all credits and payments under the Plan any taxes that the Committee reasonably determines to be required by law to be withheld from such credits and payments. 
  

	7.04  	Compliance with Section 409A 

 To the extent
that rights or payments under this Plan are subject to Section 409A of the Internal Revenue Code, the Plan shall be construed and administered in compliance with the conditions of Section 409A and regulations and other guidance issued
pursuant to Section 409A for deferral of income taxation until the time the compensation is paid. Any distribution election that would not comply with Section 409A of the Code shall not be effective for purposes of this Plan. To the extent
that a provision of this Plan does not comply with Section 409A of the Code, such provision shall be void and without effect. The Corporation does not warrant that the Plan will comply with Section 409A of the Code with respect to any
Participant or with respect to any payment. In no event shall the Corporation, any director, officer, or employee of the Corporation (other than the Participant), or any member of the Committee be liable for any additional tax, interest, or penalty
incurred by a Participant or Beneficiary as a result of the Plan’s failure to satisfy the requirements of Section 409A of the Code, or as a result of the Plan’s failure to satisfy any other requirements of applicable tax laws.

  

 14 

	7.05  	Incompetence 

 If the Committee determines, upon
evidence satisfactory to the Committee, that any Participant or Beneficiary to whom a benefit is payable under the Plan is unable to care for his or her affairs because of illness or accident or otherwise, any payment due under the Plan (unless
prior claim therefore shall have been made by a duly authorized guardian or other legal representative) may be paid, upon appropriate indemnification of the Committee and the Company, to the spouse of the Participant or Beneficiary or other person
deemed by the Committee to have incurred expenses for the benefit of and on behalf of such Participant or Beneficiary. Any such payment shall be a complete discharge of any liability under the Plan with respect to the amount so paid. 
  

	7.06  	Inability to Locate Participants and Beneficiaries 

 Each Participant and Beneficiary entitled to receive a payment under the Plan shall keep the Committee advised of his or her current address. If the Committee is unable to locate a Participant or Beneficiary to whom a payment is due under
the Plan, the total amount payable to such Participant or Beneficiary shall be forfeited as of the last day of the calendar year in which the payment first becomes due. 
  

	7.07  	Successors 

 The provisions of the Plan shall bind
and inure to the benefit of the Corporation and its successors and assigns. The term “successors” as used in the preceding sentence shall include any corporation or other business entity that by merger, consolidation, purchase, or
otherwise acquires all or substantially all of the business and assets of the Corporation, and any successors and assigns of any such corporation or other business entity. 
  

	7.08  	Usage 

 (a) Titles and Headings. The titles

 If any provision of the Plan is held
unlawful or otherwise invalid or unenforceable in whole or in part, such unlawfulness, invalidity, or unenforceability shall not affect any other provision of the Plan or part thereof, each of which shall remain in full force and effect. If the

made or provided under the Plan, and if the making of any payment in full or the provision of any other benefit required under the Plan in full would be unlawful or otherwise invalid or unenforceable, then such unlawfulness, invalidity, or
unenforceability shall not prevent such payment or benefit from being made or provided in part, to the extent that it would not be unlawful, invalid, or unenforceable, and the maximum payment or benefit that would not be unlawful, invalid, or
unenforceable shall be made or provided under the Plan.

 ARTICLE I 
 INTRODUCTION 
  

	1.01  	Purpose of Plan 

 The purpose of the Plan is to
enhance the Company’s ability to attract and retain non-employee members of the Board whose training, experience and ability will promote the interests of the Company and to directly align the interests of such non-employee Directors with the
interests of the Company’s shareowners by providing compensation based on the value of UTC Common Stock. The Plan is designed to permit such non-employee directors to defer the receipt of all or a portion of the cash compensation otherwise
payable to them for services to the Company as members of the Board. 
  

	1.02  	Effective Date of Plan 

 Except as otherwise
provided by Section 3.01, the Plan shall apply only to a Participant’s annual Director’s retainer Fees with respect to service on and after January 1, 1996. 
 ARTICLE II 
 DEFINITIONS 
 Unless the context clearly indicates otherwise, the following terms, when used in capitalized form in the Plan, shall have the meanings set forth below:

 Account shall mean a bookkeeping account established for a Participant under Section 4.01. 
 Article shall mean an article of the Plan. 
 Beneficiary shall mean a Participant’s beneficiary, designated in writing and in a form and manner satisfactory to the Committee, or if a Participant fails to designate a beneficiary, or if the
Participant’s designated Beneficiary predeceases the Participant, the Participant’s estate. 
  

 19 

 Board shall mean the Board of Directors of the Company. 
 Closing Price shall mean, with respect to any date specified by the Plan, the closing price of UTC Common Stock on the composite tape of

 Committee shall mean the Nominating Committee of the Board. 
 Company shall mean
United Technologies Corporation. 
 Director’s Fees shall mean the annual retainer fee payable to a Participant for
services to the Company as a member of the Board. Director’s Fees do not include special meeting fees. 
 Participant
shall mean each member of the Board (other than a member of the Board who is also an employee of the Company or a subsidiary thereof) who is or becomes a member of the Board on or after January 1, 1996. 
 Payment Anniversary Date shall mean an anniversary of the Payment Commencement Date. 
 Payment Commencement Date shall mean the first business day of the first month following the month in which the Participant terminates
service as a member of the Board. 
 Plan shall mean this United Technologies Corporation Board of Directors Deferred Stock
Unit Plan, as set forth herein and as amended from time to time. 
 Plan Year shall mean the calendar year. 
 Section shall mean a section of the Plan. 
  

 20 

 Stock Unit shall mean a hypothetical share of UTC Common Stock as described in
Section 4.02. 
 UTC Common Stock shall mean the common stock of the Company. 
 ARTICLE III 
 CREDITS

  

	3.01  	Transition Credits 

 As soon as practicable on or
after January 1, 1996, the Company shall credit to the Account of each Participant a number of Stock Units determined in accordance with the schedules set forth in Appendix I and Appendix II to the Plan. The credits set forth in Appendix I
shall be provided in lieu of any benefits to which the Participant otherwise would have been entitled under the United Technologies Corporation Directors Retirement Plan as of its termination on December 31, 1995. The credits set forth in
Appendix II shall be provided in lieu of any benefits to which the Participant otherwise would be entitled under certain deferred compensation arrangements entered into prior to January 1, 1996. The number of units set forth in Appendix II
shall equal the number of tax deferred stock units (if any) credited to the Participant under any such prior deferred compensation arrangement, determined as of December 31, 1995. 
  

	3.02  	Automatic Credits 

 As of the beginning of each Plan
Year, the Company shall credit Stock Units to each Participant’s Account equal in value to 60% of the Participant’s Director’s Fees for the Plan Year, as determined in accordance with Section 4.02(a)(1). 
  

	3.03  	Elective Credits 

 A Participant may elect, with
respect to each Plan Year, to defer the entire portion (but not a partial portion) of the 40% of the Participant’s Director’s Fees that are not automatically deferred in accordance with Section 3.02 and that otherwise would be paid to
the Participant in cash. If the Participant makes such an election, the Company shall credit Stock Units to the 

  

 21 

 
Participant’s Account equal in value to 40% of the Participant’s Director’s Fees for the Plan Year, as determined in accordance with
Section 4.02(a)(I), as of the beginning of the Plan Year with respect to which the election is made (or, if later, as of the first day in the Plan Year on which the individual becomes a Participant). An election under this Section 3.03
shall be made in a form and manner satisfactory to the Committee and shall be effective for a Plan Year only if made before the beginning of the Plan Year; provided that an individual who becomes a Participant after the first day of a Plan Year may
make the election for that Plan Year within 30 days of becoming a Participant. 
 ARTICLE IV 
 ACCOUNTS AND INVESTMENTS 
  

	4.01  	Accounts 

 A separate Account under the Plan shall
be established for each Participant. Such Account shall be (a) credited with the amounts credited in accordance with Article Ill, (b) credited (or charged, as the case may be) with the investment results determined in accordance with
Section 4.02, and (c) charged with the amounts paid by the Plan to or on behalf of the Participant in accordance with Article V. Within each Participant’s Account, separate subaccounts shall be maintained to the extent the Committee
determines them to be necessary or useful in the administration of the Plan. 
  

	4.02  	Stock Units 

 (a) Deemed Investment in UTC Common
Stock. Except as provided in subsection (b), below, a Participant’s Account shall be treated as if it were invested in Stock Units that are equivalent in value to the fair market value of shares of UTC Common Stock in accordance with the
following rules: 
 (1) Conversion into Stock Units. Any Director’s Fees credited to a Participant’s Account
for a Plan Year under Section 3.02 or 3.03 shall be converted into Stock Units (including fractional Stock Units) by dividing the amount credited by the Closing Price on the first business day of the Plan Year; provided that in the case of an
individual who becomes a Participant after the first day of a Plan Year, the Closing Price shall be determined as of the day on which the individual becomes a Participant. 
  

 22 

 (2) Deemed Reinvestment Of Dividends. The number of Stock Units credited to a
Participant’s Account shall be increased on each date on which a dividend is paid on UTC Common Stock. The number of additional Stock Units credited to a Participant’s Account as a result of such increase shall be determined by
(i) multiplying the total number of Stock Units (excluding fractional Stock Units) credited to the Participant’s Account immediately before such increase by the amount of the dividend paid per share of UTC Common Stock on the dividend
payment date, and (ii) dividing the product so determined by the Closing Price on the dividend payment date. 
 (3)
Conversion Out of Stock Units. The dollar value of the Stock Units credited to a Participant’s Account on any date shall be determined by multiplying the number of Stock Units (including fractional Stock Units) credited to the
Participant’s Account by the Closing Price on that date. 
 (4) Effect of Recapitalization. In the event of a
transaction or event described in this paragraph (4), the number of Stock Units credited to a Participant’s Account shall be adjusted in such manner as the Committee, in its sole discretion, deems equitable. A transaction or event is described
in this paragraph (4) if (i) it is a dividend (other than regular quarterly dividends) or other distribution (whether in the form of cash, shares, other securities, or other property), extraordinary cash dividend, recapitalization, stock
split, reverse stock split reorganization, merger, consolidation, split-up, spin-off, repurchase, or exchange of shares or other securities, the issuance or exercisability of stock purchase rights, the issuance of warrants or other rights to
purchase shares or other securities, or other similar corporate transaction or event and (ii) the Committee determines that such transaction or event affects the shares of UTC Common Stock, such that an adjustment pursuant to this paragraph
(4) is appropriate to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. 
  

 23 

 (b) Change in Deemed Investment Election. A Participant who elects to receive distribution of his
or her Accounts in annual installments will continue to have such Account credited with Stock Units during the installment period unless the Participant irrevocably elects to have his or her Account treated, as of the Payment Commencement Date, as
if the Account were invested in cash. If a Participant makes such election, the Account will be credited with a rate of interest equal to the average interest rate on 10-Year Treasury Bonds as of the January through October Period in the calendar
year prior to the Plan Year in which the interest is credited, plus I %. An election under this subsection (b) shall be made in a form and manner satisfactory to the Committee and shall be effective only if made before the Payment Commencement
Date. 
  

	4.03  	Hypothetical Nature of Accounts and Investments 

 Each Account established under this Article IV shall be maintained for bookkeeping purposes only. Neither the Plan nor any of the Accounts established under the Plan shall hold any actual funds or assets. The Stock Units established
hereunder shall be used solely to determine the amounts to be paid hereunder, shall not be or represent an equity security of the Company, shall not be convertible into or otherwise entitle a Participant to acquire an equity security of the Company
and shall not carry any voting or dividend rights. 
 ARTICLE V 
 PAYMENTS 
  

	5.01  	Entitlement to Payment 

 Credits to a
Participant’s Account under Section 3.02 or 3.03 shall be in lieu of payment to the Participant of the related Director’s Fees. Any payment under the Plan with respect to an Account shall be made solely in cash and as further provided
in this Article V. The right of any person to receive one or more payments under the Plan shall be an unsecured claim against the general assets of the Company. 
  

 24 

	5.02  	Payment Commencement Date 

 Payments to a
Participant with respect to the Participant’s Account shall begin as of the Participant’s Payment Commencement Date; provided that if a Participant dies before the Participant’s Payment Commencement Date, payment of the entire value
of the Participant’s Account shall be made in a lump sum to the Participant’s Beneficiary as soon as practicable after the Committee receives all documents and other information that it requests in connection with the payment. 

 

	5.03  	Form and Amount of Payment 

 (a) Fifteen Annual
Installments. A Participant shall receive his or her benefits in 15 annual installments unless the Participant elects to receive his or her benefits under the Plan in the form of a lump-sum payment or in less than 15 annual installments in
accordance with subsection (b), below. Annual installments shall be payable to the Participant in cash beginning as of the Payment Commencement Date and continuing as of each Payment Anniversary Date thereafter until all installments have been paid.
The first annual installment shall equal one- fifteenth (1/15th) of the value of the Stock Units credited to the Participant’s Account, determined as of the Payment Commencement Date. Each successive annual installment shall equal the
value of the Stock Units credited to the Participant’s Account, determined as of the Payment Anniversary Date, multiplied by a fraction, the numerator of which is one, and the denominator of which is the excess of 15 over the number of
installment payments previously made (i.e., 1/14th, 1/13th, etc.). If the Participant dies after the Participant’s Payment Commencement Date but before all 15 installments have been paid, the remaining installments shall be paid to the
Participant’s Beneficiary in accordance with the schedule in this subsection (a). 
 (b) Lump Sum, or Less Than 15 Annual
Installments. A Participant may elect to receive his or her benefits under the Plan in the form of a lump-sum payment or in two to fourteen installments in lieu of the fifteen installment payments determined under subsection (a), above. The lump
sum shall be payable to the Participant in cash as of the Payment Commencement Date and shall equal the value of the Stock Units credited to the Participant’s Account, determined as of the Payment Commencement Date. Installments shall be paid
in the 

  

 25 

 
manner set forth in subsection (a) above, except that for purposes of determining the amount of the first annual installment, the denominator of the
fraction shall equal the number of scheduled annual installments. An election under this subsection (b) shall be made in a form and manner satisfactory to the Committee and shall be effective only if made at least two years before the
Participant’s Payment Commencement Date. 
 ARTICLE VI 
 ADMINISTRATION 
  

	6.01  	In General 

 The Committee shall have the
discretionary authority to interpret the Plan and to decide any and all matters arising under the Plan, including without limitation the right to determine eligibility for participation, benefits, and other rights under the Plan; the right to
determine whether any election or notice requirement or other administrative procedure under the Plan has been adequately observed; the right to determine the proper recipient of any distribution under the Plan; the right to remedy possible
ambiguities, inconsistencies, or omissions by general rule or particular decision; and the right otherwise to interpret the Plan in accordance with its terms. Except as otherwise provided in Section 6.03, the Committee’s determination on
any and all questions arising out of the interpretation or administration of the Plan shall be final, conclusive, and binding on all parties. 
  

	6.02  	Plan Amendment and Termination 

 The Committee may
amend, suspend, or terminate the Plan at any time; provided that no amendment, suspension, or termination of the Plan shall, without a Participant’s consent, reduce the Participant’s benefits accrued under the Plan before the date of such
amendment, suspension, or termination. If the Plan is terminated in accordance with this Section 6.02, the terms of the Plan as in effect immediately before termination shall determine the right to payment in respect of any amounts that remain
credited to a Participant’s or Beneficiary’s Account upon termination. 
  

 26 

	6.03  	Reports to Participants 

 The Committee shall
furnish an annual statement to each Participant (or Beneficiary) reporting the value of the Participant’s (or Beneficiary’s) Account as of the end of the most recent Plan Year. 
  

	6.04  	Delegation of Authority 

 The Committee may delegate
to officers of the Company any and all authority with which it is vested under the Plan, and the Committee may allocate its responsibilities under the Plan among its member. 
 ARTICLE VII 
 MISCELLANEOUS 
  

	7.01  	Rights Not Assignable 

 No payment due under the
Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge in any other way. Any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge such payment in
any other way shall be void. No such payment or interest therein shall be liable for or subject to the debts, contracts, liabilities, or torts of any Participant or Beneficiary. If any Participant or Beneficiary becomes bankrupt or attempts to
anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge in any other way any payment under the Plan, the Committee may direct that such payment be suspended and that all future payments to which such Participant or Beneficiary
otherwise would be entitled be held and applied for the benefit of such person, the person’s children or other dependents, or any of them, in such manner and in such proportions as the Committee may deem proper. 
  

	7.02  	Certain Rights Reserved 

 Nothing in the Plan shall
confer upon any person the right to continue to serve as a member of the Board or to participate in the Plan other than in accordance with its terms. 
  

 27 

	7.03  	Withholding Taxes 

 The Committee may make any
appropriate arrangements to deduct from all credits and payments under the Plan any taxes that the Committee reasonably determines to be required by law to be withheld from such credits and payments. 
  

	7.04  	Incompetence 

 If the Committee determines, upon
evidence satisfactory to the Committee, that any Participant or Beneficiary to whom a benefit is payable under the Plan is unable to care for his or her affairs because of illness or accident or otherwise, any payment due under the Plan (unless
prior claim therefore shall have been made by a duly authorized guardian or other legal representative) may be paid, upon appropriate indemnification of the Committee and the Company, to the spouse of the Participant or Beneficiary or other person
deemed by the Committee to have incurred expenses for the benefit of and on behalf of such Participant or Beneficiary. Any such payment shall be a complete discharge of any liability under the Plan with respect to the amount so paid. 
  

	7.05  	Inability to Locate Participants and Beneficiaries 

 Each Participant and Beneficiary entitled to receive a payment under the Plan shall keep the Committee advised of his or her current address. If the Committee is unable for a period of 36 months to locate a Participant or Beneficiary to
whom a payment is due under the Plan, commencing with the first day of the month as of which such payment first comes due, the total amount payable to such Participant or Beneficiary shall be forfeited. Should such a Participant or Beneficiary
subsequently contact the Committee requesting payment, the Committee shall, upon receipt of all documents and other information that it might request in connection with the payment, restore and pay the forfeited payment in a lump sum, the value of
which shall not be adjusted to reflect any interest or other type of investment earnings or gains for the period of forfeiture. 
  

 28 

	7.06  	Successors 

 The provisions of the Plan shall bind
and inure to the benefit of the Company and its successors and assigns. The term “successors” as used in the preceding sentence shall include any corporation or other business entity that by merger, consolidation, purchase, or otherwise
acquires all or substantially all of the business and assets of the Company, and any successors and assigns of any such corporation or other business entity. 
  

	7.07  	Usage 

 (a) Titles and Headings. The titles
to Articles and the headings of Sections, subsections, and paragraphs in the Plan are placed herein for convenience of reference only and shall be of no force or effect in the interpretation of the Plan 
 (b) Number. The singular form shall include the plural, where appropriate. 
  

	7.08  	Severability 

 If any provision of the Plan is held
unlawful or otherwise invalid or unenforceable in whole or in part, such unlawfulness, invalidity, or unenforceability shall not affect any other provision of the Plan or part thereof, each of which shall remain in full force and effect. If the
making of any payment or the provision of any other benefit required under the Plan is held unlawful or otherwise invalid or unenforceable, such unlawfulness, invalidity or unenforceability shall not prevent any other payment or benefit from being
made or provided under the Plan, and if the making of any payment in full or the provision of any other benefit required under the Plan in full would be unlawful or otherwise invalid or unenforceable, then such unlawfulness, invalidity, or
unenforceability shall not prevent such payment or benefit from being made or provided in part, to the extent that it would not be unlawful, invalid, or unenforceable, and the maximum payment or benefit that would not be unlawful, invalid, or
unenforceable shall be made or provided under the Plan. 
  

	7.09  	Governing Law 

 The Plan and all determinations made
and actions taken under the Plan shall be governed by and construed in accordance with the laws of the State of Connecticut.

the amount thereof, and the anticipated closing date, together with copies of drafts of the material definitive documents therefor and, when completed, copies of the final versions of such material definitive 

  

 5 

 
documents, (ii) at the time of incurring such Permitted Debt (A) no Default has occurred and is then continuing and (B) no Default would
result from the incurrence of such Permitted Debt after giving effect to the incurrence of such Permitted Debt (and any concurrent repayment of Debt with the proceeds of such incurrence), (iii) the incurrence of such Permitted Debt (and any

 2.6 Amendment to Section 9.18. Section 9.18 is hereby amended by deleting such
Section in its entirety and replacing it with the following: 
 “Section 9.18 Swap Agreements. The Borrower will
not, and will not permit any Subsidiary to, enter into any Swap Agreements with any Person other than 
 (a) Swap Agreements
in respect of 
 (i) crude oil (A) with an Approved Counterparty and (B) the notional volumes for which do not
exceed, 
 (1) for the three-year period following the date such Swap Agreement is executed, the greater of (I) 70% of
the reasonably anticipated projected crude oil production from proved, probable and possible Oil and Gas Properties; and (II) 80% of the reasonably anticipated projected crude oil production from proved developed, producing Oil and Gas Properties,
and 
 (2) for periods thereafter to the sixtieth month following the date such Swap Agreement is executed, 90% of the
reasonably anticipated projected crude oil production from proved developed, producing Oil and Gas Properties, and 
 (3) no
Swap Agreement in respect of crude oil shall have a tenor of greater than sixty months from the date such Swap Agreement is executed; 
 (ii) natural gas (A) with an Approved Counterparty and (B) the notional volumes for which do not exceed 
  

 6 

 (1) for the three-year period following the date such Swap Agreement is executed, the
greater of (I) 70% of the reasonably anticipated projected natural gas production from proved, probable and possible Oil and Gas Properties; and (II) 80% of the reasonably anticipated projected natural gas production from proved developed,
producing Oil and Gas Properties, and 
 (2) for periods thereafter to the sixtieth month following the date such Swap
Agreement is executed, 90% of the reasonably anticipated projected natural gas production from proved developed, producing Oil and Gas Properties, and 
 (3) no Swap Agreement in respect of natural gas shall have a tenor of greater than sixty months from the date such Swap Agreement is executed; 
 (iii) the projections in subsections (i) and (ii) above will be adjusted as follows: (A) Oil and Gas Properties evaluated
in the most recently delivered Reserve Report shall reflect the actual historical decline profile of such Oil and Gas Properties and (B) Oil and Gas Properties not evaluated in the most recently delivered Reserve Report shall reflect a
reasonable decline profile based upon actual historical decline profiles of similar or analogous Oil and Gas Properties for each month during the period during which such Swap Agreement is in effect for each of crude oil and natural gas, calculated
separately, provided, however, that for purposes of this Section 9.18(a), put options and price floors for crude oil and natural gas shall be disregarded; 
 (b) Swap Agreements in respect of interest rates with an Approved Counterparty, as follows: 
 (i) Swap Agreements effectively converting interest rates from fixed to floating, the notional amounts of which (when aggregated with all
other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from fixed to floating) do not exceed 50% of the then outstanding principal amount of the Borrower’s Debt for borrowed money which
bears interest at a fixed rate, and 
 (ii) Swap Agreements effectively converting interest rates from floating to fixed, the
notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 75% of the then outstanding principal amount of
the Borrower’s Debt for borrowed money which bears interest at a floating rate; and 
 (c) Swap Agreements permitted
under (a) and (b) which are otherwise in compliance with the Borrower’s current hedging policies which have been in effect prior to the Effective Date or which are thereafter approved in accordance with the policies and procedures
authorized by the Borrower’s board of directors from time to time. 
  

 7 

 In no event shall any Swap Agreement (i) contain any requirement, agreement or covenant for the
Borrower or any Subsidiary to post collateral or margin to secure their obligations under such Swap Agreement or to cover market exposures except to the extent permitted by Section 9.03(d) or (ii) be entered into for speculative purposes.
Concurrently with the delivery of each Reserve Report, the Borrower will furnish a projection of its reasonably anticipated projection of natural gas and crude oil (which shall reflect the adjustments referred to above) for the 36-month period
commencing with the end of the calendar month during which the associated Reserve Report is delivered. The Borrower may supplement or update such projections at any time without any obligation to do so (but subject to the representation contained in
Section 7.11). 
 During any quarterly period, the aggregate notional volumes of all Swap Agreements which were in effect during such
period (other than basis differential swaps) for each of natural gas and crude oil shall not exceed the actual production volumes for each of natural gas and crude oil during such period.” 
 2.7 Section 12.02(b). Clauses (ii), (vi), (vii) and (viii) of Section 12.02(b) are hereby amended by adding the words
“(other than any Defaulting Lender)” after the words “each Lender” in each such clause. 
 2.8 Schedule 9.02.
Schedule 9.02 attached to this Third Amendment is hereby added to the Credit Agreement. 
 Section 3. Assignments; Borrowing Base. 
 3.1 Assignments; Additional Lenders, Increasing Lenders and Reallocation of Commitments and Loans. The Lenders have agreed among themselves, in
consultation with the Borrower, to (i) reallocate their respective Maximum Credit Amounts and Commitments and to, among other things, (ii) allow each of Barclays Bank plc and Guaranty Bank and Trust Company to become a party to the Credit
Agreement as an Additional Lender by acquiring an interest in the Aggregate Maximum Credit Amounts and Commitments and (iii) to increase the Maximum Credit Amounts and Commitment of JPMorgan Chase Bank, N.A., Deutsche Bank Trust Company
Americas, Bank of America, N.A., U.S. Bank National Association, and Compass Bank (each, an “Increasing Lender”). The Administrative Agent and the Borrower hereby consent to such reallocation and each Additional Lender’s and
Increasing Lender’s acquisition of an interest in the Aggregate Maximum Credit Amounts and Commitments. On October 20, 2008 and after giving effect to such reallocations, the Maximum Credit Amounts and Commitment of each Lender shall be as
set forth on Annex I of this Third Amendment which Annex I supersedes and replaces the existing Annex I to the Credit Agreement. With respect to such reallocation, (i) each Additional Lender and each Increasing Lender shall be deemed to have
acquired the Maximum Credit Amounts and Commitment allocated to it from each of the other Lenders pursuant to the terms of an Assignment and Assumption Agreement in the form attached as 

  

 8 

 
Exhibit G to the Credit Agreement as if such New Lender, such Increasing Lender and the other Lenders had executed an Assignment and Assumption
Agreement with respect to such allocation and (ii) upon (a) payment of the $3,500 fee to the Administrative Agent, and (b) in the case of an Additional Lender, delivery by such Additional Lender of (1) an Administrative
Questionnaire and (2) if necessary, delivery of any documentation required by Section 5.03(e) of the Credit Agreement, each Additional Lender and each Increasing Lender shall be deemed to have complied with the requirements of
Section 2.06(c)(ii)(E) or Section 2.06(c)(ii)(F), as the case may be. On October 20, 2008, the Borrower will deliver to each Additional Lender and each Increasing Lender, a Note (or new Note, as the case may be) payable to the order
of such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase, and otherwise duly completed, and each Lender receiving a replacement Note agrees to promptly thereafter return the previously issued Note
held by such Lender marked canceled or otherwise similarly defaced. 
 3.2 Borrowing Base. For the period from and including
October 20, 2008 until the next Redetermination Date, the Borrowing Base is $600,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e),
Section 8.13(c), Section 9.12 or Section 9.19. 
 Section 4. Conditions Precedent. This Third Amendment shall not become effective
until the date on which each of the following conditions is satisfied (or waived in accordance with Section 12.02 of the Credit Agreement): 
 4.1 The Administrative Agent shall have received from each Lender, counterparts (in such number as may be requested by the Administrative Agent) of this Third Amendment signed on behalf of such Person. 
 4.2 The Administrative Agent shall have received the fees set forth in the fee letter between the Borrower and the Administrative Agent of even date
herewith. 
 4.3 No Default shall have occurred and be continuing as of the date hereof, after giving effect to the terms of this Third
Amendment. 
 4.4 The Administrative Agent shall have received such Note(s) required pursuant to Section 3.1 of this Third Amendment.

 4.5 The Administrative Agent shall have received such other documents as the Administrative Agent or its special counsel may reasonably
require. 
 The Administrative Agent is hereby authorized and directed to declare this Third Amendment to be effective when it has received
documents confirming or certifying, to the satisfaction of the Administrative Agent, compliance with the conditions set forth in this Section 4 or the waiver of such conditions as permitted hereby. Such declaration shall be final, conclusive
and binding upon all parties to the Credit Agreement for all purposes. 
  

 9 

 Section 5. Miscellaneous. 
 5.1 Confirmation. The provisions of the Credit Agreement, as amended by this Third Amendment, shall remain in full force and effect following the effectiveness of this Third Amendment. 
 5.2 Ratification and Affirmation; Representations and Warranties. Each Obligor hereby (a) acknowledges the terms of this Third Amendment;
(b) ratifies and affirms its obligations under, and acknowledges, renews and extends its continued liability under, each Loan Document to which it is a party and agrees that each Loan Document to which it is a party remains in full force and
effect, except as expressly amended hereby, notwithstanding the amendments contained herein and (c) represents and warrants to the Lenders that as of the date hereof, after giving effect to the terms of this Third Amendment: (i) all of the
representations and warranties contained in each Loan Document to which it is a party are true and correct, except to the extent any such representations and warranties are expressly limited to an earlier date, in which case, such representations
and warranties shall continue to be true and correct as of such specified earlier date, (ii) no Default or Event of Default has occurred and is continuing, (iii) no event or events have occurred which individually or in the aggregate could
reasonably be expected to have a Material Adverse Effect and (iv) the Mortgaged Properties represent at least 80% of the total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report. 
 5.3 Counterparts. This Third Amendment may be executed by one or more of the parties hereto in any number of separate counterparts, and all of
such counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of this Third Amendment by facsimile or electronic transmission in portable document format (.pdf) shall be effective as delivery of a manually
executed counterpart hereof. 
 5.4 No Oral Agreement. This Third Amendment, the Credit Agreement and the other Loan Documents
executed in connection herewith and therewith represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous, or unwritten oral agreements of the parties. There are no subsequent oral agreements
between the parties. 
 5.5 GOVERNING LAW. THIS THIRD AMENDMENT (INCLUDING, BUT NOT LIMITED TO, THE VALIDITY AND ENFORCEABILITY
HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 5.6 Payment of Expenses. In
accordance with Section 12.03 of the Credit Agreement, the Borrower agrees to pay or reimburse the Administrative Agent for all of its reasonable out-of-pocket costs and reasonable expenses incurred in connection with this Third Amendment, any
other documents prepared in connection herewith and the transactions contemplated hereby, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent. 
  

 10 

 5.7 Severability. Any provision of this Third Amendment which is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 5.8 Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.
