MERGER

SECTION 2.1 Closing of the Merger.

(a) Closing Date. Subject to the satisfaction or waiver of the conditions (other than those conditions that are not legally permitted to be waived) to closing set forth in Article VI, the closing (the “Closing”) of the Merger and the transactions contemplated by this Section 2.1 shall be held at the offices of Parent at Xxx Xxxxxxxx Xxxxxx, Xxxxx, Xxxxxxxx 00000-0000 on the next Business Day following the satisfaction or waiver (other than those conditions that are not legally permitted to be waived) of all of the conditions set forth in Article VI (other than conditions that would normally be satisfied on the Closing Date, but subject to satisfaction or waiver (other than those conditions that are not legally permitted to be waived) of those conditions) commencing at 9:00 a.m., local time, or such other place, date and time as may be mutually agreed upon in writing by the parties hereto. The “Closing Date,” as referred to herein, shall mean the date on which the Closing actually occurs.

(b) Effective Time. Concurrently with or as soon as practicable following the Closing, Parent and WPZ shall cause a certificate of merger effecting the Merger (the “Certificate of Merger”) to be filed with the Secretary of State of the State of Delaware, duly executed in accordance with the relevant provisions of DRULPA and DLLCA, as applicable (the date and time of such filing (or, if agreed by the parties hereto, such later time and date as may be expressed therein as the effective date and time of the Merger) being the “Effective Time”). Parent shall cause the Charter Amendment, duly executed in accordance with the relevant

provisions of DGCL, to be filed with the Secretary of State of the State of Delaware prior to the filing of the Certificate of Merger, and the Charter Amendment shall become effective at or prior to the Effective Time. Upon the terms and subject to the conditions of this Agreement, at the Effective Time, Merger Sub shall merge with and into WPZ, the separate existence of Merger Sub shall cease, and WPZ shall continue as the surviving limited partnership in the Merger (the “Surviving Entity”).

(c) Effect of the Merger on Equity Securities. Subject in each case to Sections 2.1(e) and 2.1(f), at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, WPZ, WPZ General Partner, any Holder of WPZ Units, any Holder of Parent Common Stock, or any other Person:

(i) Conversion of WPZ Public Units. Each of the WPZ Public Units outstanding immediately prior to the Effective Time shall be converted into the right to receive 1.115 shares of validly issued, fully paid and nonassessable Parent Common Stock (such number of shares of Parent Common Stock, the “Merger Consideration”).

(ii) Each WPZ Public Unit, upon being converted into the right to receive the Merger Consideration pursuant to this Section 2.1(c), shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each Holder of such WPZ Public Units immediately prior to the Effective Time shall thereafter cease to be a limited partner of WPZ or have any rights with respect to such WPZ Public Units, except the right to receive the Merger Consideration, and any distributions and Fractional Share Payments to which former Holders of WPZ Public Units become entitled all in accordance with this Article II upon the Surrender of (A) a certificate that immediately prior to the Effective Time represented WPZ Public Units (a “WPZ Certificate”) or (B) uncertificated WPZ Public Units represented by book-entry (“Book-Entry WPZ Common Units”), together with such properly completed and duly executed Letter of Transmittal and such other documents in accordance with Section 2.2.

(iii) Treatment of WPZ-Owned Units and Parent-Owned Partnership Interests. Any WPZ Units that are owned immediately prior to the Effective Time by WPZ shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled WPZ Units. All (a) WPZ General Partner Interest, (b) WPZ Class B Units, (c) WPZ Incentive Distribution Rights, and (d) WPZ Units that are not WPZ Public Units or not cancelled pursuant to the first sentence of this clause (iii) shall, in each case, remain outstanding as partnership interests in the Surviving Entity, unaffected by the Merger.

(iv) Equity of Merger Sub. The outstanding limited liability company interest in Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into an aggregate number of common units of the Surviving Entity equal to the number of WPZ Public Units that are converted into the right to receive the Merger Consideration pursuant to Section 2.1(c)(i). At the Effective Time, the books and records of WPZ shall be revised to reflect the cancellation and retirement of all WPZ Public Units and the conversion of the limited liability company interest in Merger Sub to common units of the Surviving Entity, and the existence of WPZ (as the Surviving Entity) shall continue without dissolution.

(d) Governing Documents of Parent. Subject to receipt of the Parent Charter Approval, the certificate of incorporation of Parent shall be amended at or prior to the Effective Time as set forth in Exhibit A (the “Charter Amendment”), and such certificate of incorporation, as amended by the Charter Amendment, shall be the certificate of incorporation of Parent until thereafter amended or changed as provided herein or by applicable Law.

(e) Other Effects of the Merger. The Merger shall be conducted in accordance with and shall have the effects set forth in this Agreement and the applicable provisions of DRULPA and DLLCA. At the Effective Time, (i) the certificate of limited partnership of WPZ shall continue as the certificate of limited partnership of the Surviving Entity, and (ii) the WPZ Partnership Agreement shall remain unchanged and shall continue as the agreement of limited partnership of the Surviving Entity, until duly amended in accordance with applicable Law and the terms of the WPZ Partnership Agreement.

(f) No Fractional Shares. Notwithstanding any other provision of this Agreement, (i) no certificates or scrip representing fractional shares of Parent Common Stock shall be issued in the Merger and (ii) each registered Holder of WPZ Public Units exchanged pursuant to the Merger who would otherwise have been entitled to receive a fractional share of Parent Common Stock (after taking into account all WPZ Public Units held by such Holder immediately prior to the Effective Time) shall receive from Parent, in lieu of such fractional share, an amount (a “Fractional Share Payment”) in cash (payable in dollars, without interest) equal to the product of (A) such fraction, multiplied by (B) the average of the closing price of Parent Common Stock as reported on the NYSE Composite Transactions Tape (as reported by Bloomberg Financial Markets or such other source as the parties shall agree in writing) over the five trading day period ending on the third trading day immediately preceding the Effective Time.

(g) Certain Adjustments. If between the Execution Date and the Effective Time, whether or not permitted pursuant to the terms of this Agreement, the number of outstanding WPZ Common Units or shares of Parent Common Stock shall be changed into a different number of units, shares or other securities (including any different class or series of securities) by reason of any dividend or distribution payable in partnership interests, voting securities, equity interests or Rights, subdivision, reclassification, split, split-up, combination, merger, consolidation, reorganization, exchange or other similar transaction, or any such transaction shall be authorized, declared or agreed upon with a record date at or prior to the Effective Time, then the Merger Consideration, and any other similarly dependent items shall be appropriately adjusted to reflect fully the effect of such transaction and to provide to WPZ, Merger Sub and the Holders of WPZ Phantom Unit Awards and WPZ Public Units the same economic effect as contemplated by this Agreement prior to such event, and thereafter, all references in this Agreement to the Merger Consideration, and any other similarly dependent items shall be references to the Merger Consideration, and any other similarly dependent items, as so adjusted; provided, however, that nothing in this Section 2.1(g) shall be deemed to permit or authorize any party hereto to effect any such dividend or distribution payable in equity securities or Rights, subdivision, reclassification, split, split-up, combination, merger,

consolidation, reorganization, exchange or other similar transaction, or the authorization, declaration or agreement to do such transaction that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement.

SECTION 2.2 Exchange of WPZ Public Units.

(a) Exchange Agent. Prior to the mailing of the Consent Statement/Prospectus/Parent Proxy Statement, Parent shall appoint Computershare Trust Company, N.A. to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration, any dividends and other distributions pursuant to Section 2.2(c) and any Fractional Share Payment. At or prior to the Closing, Parent shall (i) deposit (or cause to be deposited) with the Exchange Agent, for the benefit of the Holders of WPZ Public Units, an amount of cash sufficient to effect the delivery of the estimated aggregate Fractional Share Payment (the “Exchange Fund”), (ii) reserve with the Exchange Agent the shares of Parent Common Stock to be issued pursuant to Section 2.1(c)(i), and (iii) authorize the Exchange Agent to exchange shares of Parent Common Stock in accordance with this Section 2.2. Parent shall deposit with the Exchange Agent any additional cash or other consideration as applicable in excess of the Exchange Fund as and when necessary to pay any dividends and other distributions pursuant to Section 2.2(c), any Fractional Share Payment and other amounts required to be paid under this Agreement. Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process. Any shares of Parent Common Stock, or fraction thereof, and any remaining amount of the Exchange Fund or other funds deposited shall be returned to Parent after the earlier to occur of (x) payment in full of all amounts due to the Holders of WPZ Public Units and (y) the expiration of the period specified in Section 2.2(e).

(b) Exchange Procedures. Promptly after the Effective Time, Parent shall, or shall cause the Exchange Agent to, mail to each Holder, as of the Effective Time, of WPZ Public Units whose WPZ Public Units were converted into the right to receive the Merger Consideration a form of letter of transmittal (the “Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the WPZ Certificates shall pass, only upon proper delivery of the WPZ Certificates (or lost certificate affidavit as contemplated by Section 2.2(b)) to the Exchange Agent or, in the case of Book-Entry WPZ Common Units, upon adherence to the procedures set forth in the Letter of Transmittal, and which shall be in such customary form and have such other provisions as Parent and WPZ may reasonably agree prior to the Effective Time) and instructions for effecting the Surrender of such WPZ Certificates (or lost certificate affidavit as contemplated by Section 2.2(b)) or Book-Entry WPZ Common Units in exchange for, as applicable, whole shares of Parent Common Stock, any dividends or distributions payable pursuant to Section 2.2(c) and any Fractional Share Payment. Subject to Section 2.2(c), upon Surrender to the Exchange Agent of such WPZ Certificates (or lost certificate affidavit as contemplated by Section 2.2(b)) or Book-Entry WPZ Common Units, together with such properly completed and duly executed Letter of Transmittal and such other documents as may reasonably be required by the Exchange Agent, the Holder of a WPZ Certificate (or lost certificate affidavit as contemplated by Section 2.2(b)) or Book-Entry WPZ Common Units shall be entitled to receive in exchange therefor, as applicable, (i) that number of whole shares of Parent Common Stock (which shall be in uncertificated book-entry form unless a physical certificate is requested) to which such Holder is entitled pursuant to Section 2.1(c)(i), (ii) the Fractional Share Payment, if any, payable in lieu of any fractional shares of Parent

Common Stock otherwise issuable, and (iii) any dividends or distributions payable pursuant to Section 2.2(c) to which such Holder is entitled. The instructions for effecting the Surrender of WPZ Certificates shall set forth procedures that must be taken by the Holder of any WPZ Certificate that has been lost, destroyed or stolen; it shall be a condition to the right of such Holder to receive the Merger Consideration, the Fractional Share Payment, if any, and any distributions payable pursuant to Section 2.2(c) that the Exchange Agent shall have received, along with the Letter of Transmittal, a duly executed lost certificate affidavit, including an agreement to indemnify Parent, signed exactly as the name or names of the registered Holder or Holders of WPZ Public Units appeared on the books of WPZ immediately prior to the Effective Time, together with a customary bond and such other documents, in each case, as Parent may reasonably require in connection therewith. After the Effective Time, there shall be no further transfer on the records of WPZ or its transfer agent of WPZ Certificates or Book-Entry WPZ Common Units (provided, however, that the foregoing shall not restrict the transfer of any WPZ Partnership Interest other than the WPZ Public Units after the Effective Time); and if such WPZ Certificates or Book-Entry WPZ Common Units are presented to WPZ or its transfer agent for transfer, they shall be canceled against delivery of the appropriate Merger Consideration, any Fractional Share Payment and any distributions payable pursuant to Section 2.2(c) as hereinabove provided. Until Surrendered as contemplated by this Section 2.2(b), each WPZ Certificate or Book-Entry WPZ Common Unit shall be deemed at any time after the Effective Time to represent only the right to receive upon such Surrender the appropriate Merger Consideration, together with any distributions payable pursuant to Section 2.2(c), and Fractional Share Payment as contemplated by this Section 2.2. No interest will be paid or will accrue on any Fractional Share Payment or any distributions payable pursuant to Section 2.2(c).

(c) Dividends and Distributions with Respect to Unexchanged WPZ Public Units. No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger with a record date after the Effective Time shall be paid to the Holder of any WPZ Certificate or Book-Entry WPZ Common Units not Surrendered with respect to such shares of Parent Common Stock issuable in respect thereof until the Surrender of such WPZ Certificate or Book-Entry WPZ Common Units in accordance with this Section 2.2. Subject to the effect of applicable Laws, Parent shall pay, or cause the Exchange Agent to pay, to the Holder of each WPZ Certificate or Book-Entry WPZ Common Units, without interest, (i) at the time of Surrender of such WPZ Certificate or Book-Entry WPZ Common Units, the amount of dividends or other distributions previously paid with respect to the whole shares of Parent Common Stock issuable with respect to such WPZ Certificate or Book-Entry WPZ Common Units that have a record date after the Effective Time and a payment date on or prior to the time of Surrender and (ii) at the appropriate payment date, the amount of dividends and distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time and prior to such Surrender and a payment date subsequent to such Surrender.

(d) No Further Ownership Rights in WPZ Public Units. All Merger Consideration issued upon the Surrender for exchange of WPZ Certificates or Book-Entry WPZ Common Units in accordance with the terms of this Article II (including any Fractional Share Payment) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the WPZ Public Units heretofore represented by such WPZ Certificates or Book-Entry WPZ Common Units (including all rights to common units arrearages), subject, however, to Parent’s obligation, with respect to WPZ Public Units outstanding immediately prior to the

Effective Time, to pay any distributions with a record date prior to the Effective Time that may have been declared or made by WPZ on such WPZ Common Units in accordance with the terms of this Agreement on or prior to the Effective Time and that remain unpaid at the Closing Date.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Holders of the WPZ Certificates or Book-Entry WPZ Common Units for twelve months after the Closing Date shall be delivered to Parent, upon demand, and any Holders of the WPZ Certificates or Book-Entry WPZ Common Units who have not theretofore complied with this Section 2.2 shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for the Merger Consideration, any Fractional Share Payment and any distributions with respect to WPZ Common Units or shares of Parent Common Stock to which such Holders may be entitled.

(f) No Liability. To the extent permitted by applicable Law, none of Parent, Merger Sub, WPZ, WPZ General Partner or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration, distribution or Fractional Share Payment properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any WPZ Certificates or Book-Entry WPZ Common Units shall not have been Surrendered immediately prior to such date on which any Merger Consideration, any Fractional Share Payment or any distributions with respect to WPZ Common Units or shares of Parent Common Stock in respect of such WPZ Certificate or Book-Entry WPZ Common Units would escheat to or become the property of any Governmental Entity, any such units, cash, or distributions in respect of such WPZ Certificates or Book-Entry WPZ Common Units shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(g) Withholding Rights. Parent, Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Common Stock, as Parent, Merger Sub or the Exchange Agent reasonably deems to be required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by Parent, Merger Sub or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Parent, Merger Sub or the Exchange Agent, as the case may be.

(h) No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

SECTION 2.3 Treatment of WPZ Phantom Unit Awards.

(a) At the Effective Time, each WPZ Phantom Unit Award that is not vested and does not vest in accordance with its terms (as set forth in an applicable award agreement) as a result of the transactions contemplated by this Agreement and that is outstanding as of immediately prior to the Effective Time, shall cease to represent an award with respect to WPZ Common Units and shall be converted into an award with respect to shares of Parent Common

Stock (a “Parent Award”), subject to the same vesting and forfeiture provisions as were applicable under such WPZ Phantom Unit Award immediately prior to the Effective Time, with the number of shares of Parent Common Stock subject to each such Parent Award to be equal to the number of WPZ Common Units subject to each such WPZ Phantom Unit Award immediately prior to the Effective Time multiplied by the Merger Consideration (rounded to the nearest whole share), with any corresponding accrued but unpaid DERs (as defined in the WPZ Legacy Long-Term Incentive Plan) with respect to any WPZ Phantom Unit Awards to be assumed, remain outstanding and continue to represent an obligation with respect to the applicable Parent Award.

(b) Prior to the Effective Time, WPZ and WPZ General Partner shall take all action necessary to effectuate the provisions of this Section 2.3. WPZ and WPZ General Partner shall ensure that, as of immediately following the Effective Time, no holder of a WPZ Phantom Unit Award or participant in the WPZ Legacy Long-Term Incentive Plan or WPZ GP Long-Term Incentive Plan shall have any rights thereunder to acquire, or other rights in respect of, the equity of WPZ, the Surviving Entity or any of the WPZ Subsidiaries.

(c) Parent shall reserve for issuance a number of shares of Parent Common Stock at least equal to the number of shares of Parent Common Stock that will be subject to the Parent Awards as a result of the actions contemplated by this Section 2.3. As soon as practicable following the Effective Time, Parent shall, to the extent legally required, file a registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms, including Form S-3) with respect to the shares of Parent Common Stock subject to such Parent Awards and shall use its reasonable best efforts to maintain the effectiveness of any such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Parent Awards remain outstanding and the offering with respect thereto is required to be registered.

Each of the WPZ SEC Reports (i) complied in all material respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the Xxxxxxxx-Xxxxx Act of 2002, as amended, and the rules and regulations promulgated thereunder (the “Xxxxxxxx-Xxxxx Act”)), and (ii) as of its effective date (in the case of WPZ SEC Reports that are registration statements filed pursuant to the requirements of the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements (x) in any WPZ SEC Report that may have been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date or (y) with respect to information supplied in writing by or on behalf of Xxxxxxxx, as to which WPZ makes no representation or warranty.

principal executive officer and its principal financial officer have disclosed, based on their most recent evaluation, to WPZ’s auditors and the audit committee of the WPZ Board (x) all significant deficiencies in the designation or operation of internal controls which could adversely affect WPZ’s ability to record, process, summarize and report financial data and have identified for WPZ’s auditors any material weakness in internal controls and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in WPZ’s internal controls.

Each of the Parent SEC Reports (i) complied in all material respects with the requirements of applicable Law (including the Exchange Act, the Securities Act and the Xxxxxxxx-Xxxxx Act), and (ii) as of its effective date (in the case of Parent SEC Reports that are registration statements filed pursuant to the Securities Act) and as of its filing date did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except for any statements (x) in any Parent SEC Report that may have been modified by an amendment to such report or a subsequent report filed with the SEC prior to the Execution Date or (y) with respect to information supplied in writing by or on behalf of WPZ, as to which Parent makes no representation or warranty.

matters certified, except as to Knowledge) required by the Xxxxxxxx-Xxxxx Act, and the statements contained in any such certifications are complete and correct, and none of such entities or its officers have received notice from any Governmental Entity questioning or challenging the accuracy, completeness, form or manner of filing or submission of such certification.

permitted by the terms of the Confidentiality Agreement, dated as of April 20, 2015 between Parent and WPZ (as it may be amended from time to time, the “Confidentiality Agreement”), each party shall hold information received from the other party pursuant to this Section 5.2 in confidence in accordance with the terms of the Confidentiality Agreement.

SECTION 5.3 Certain Filings; Parent Stockholder Meeting.

(a) As promptly as practicable following the Execution Date (i) each of the WPZ Parties and the Parent Parties agrees to cooperate in the preparation of the Registration Statement (including the joint consent statement/prospectus/Parent Proxy Statement constituting a part thereof (the “Consent Statement/Prospectus/Parent Proxy Statement”)), (ii) Parent shall use its commercially reasonable efforts to cause the shares of Parent Common Stock to be issued in the Merger to be approved for listing on the NYSE (subject, if applicable, to notice of issuance) prior to the Effective Time, and (iii) the parties hereto shall make all required filings under applicable state securities and “blue sky” Laws; provided, however, that no such filings shall be required in any jurisdiction where, as a result thereof, Parent would become subject to general service of process or to taxation or qualification to do business as a foreign corporation doing business in such jurisdiction solely as a result of such filing. Parent agrees to file the Registration Statement with the SEC as promptly as reasonably practicable. Each of Parent and WPZ agrees to use all commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as practicable after filing thereof and keep the Registration Statement effective until the earlier of the consummation of the transactions contemplated by this Agreement and the termination of this Agreement in accordance with its terms. Parent shall use its reasonable best efforts to cause the Consent Statement/Prospectus/Parent Proxy Statement to be mailed to the stockholders of Parent as promptly as practicable after the Registration Statement is declared effective under the Securities Act. Each of Parent and WPZ agrees to furnish to the other party all information concerning the Parent Group Entities or the WPZ Group Entities, as applicable, and to take such other action as may be reasonably requested in connection with the foregoing. No filing of, or amendment or supplement to, the Registration Statement or the Consent Statement/Prospectus/Parent Proxy Statement will be made by Parent or WPZ, in each case without providing the other party a reasonable opportunity to review and comment thereon.

(b) Each of the Parent Parties and the WPZ Parties agrees, as to itself and its Subsidiaries, that (i) none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Consent Statement/Prospectus/Parent Proxy Statement and any amendment or supplement thereto will, at the date the Consent Statement/Prospectus/Parent Proxy Statement is mailed to the Holders of WPZ Common Units or Parent Common Stock, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the Parent Parties and the WPZ Parties further agrees that, if it shall become aware prior to the Closing Date of any information that would cause any of the statements in the Registration

Statement or the Consent Statement/Prospectus/Parent Proxy Statement to be false or misleading with respect to any material fact, or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not false or misleading, it will promptly inform the other party thereof and take the necessary steps to correct such information in an amendment or supplement to the Registration Statement or Consent Statement/Prospectus/Parent Proxy Statement.

(c) Each of WPZ and Parent shall (1) promptly notify the other of receipt of any comments from the SEC or its staff or any other applicable government official and of any requests by the SEC or its staff or any other applicable government official for amendments or supplements to any of the filings with the SEC in connection with the Merger and other transactions contemplated hereby or for additional information and (2) promptly supply the other with copies of all correspondence between WPZ or any of its representatives, or Parent or any of its representatives, as the case may be, on the one hand, and the SEC or its staff or any other applicable government official, on the other hand, with respect thereto. Parent and WPZ shall use their respective commercially reasonable efforts to respond to any comments of the SEC or its staff with respect to the Consent Statement/Prospectus/Parent Proxy Statement or the Registration Statement as promptly as practicable.

(d) WPZ General Partner shall distribute to the Holders of WPZ Units the Consent Statement/Prospectus/Parent Proxy Statement, which shall include a form of consent that may be executed by Holders of WPZ Units in connection with the Written Consent as promptly as practicable after the Registration Statement is declared effective under the Securities Act.

(e) Parent shall, as soon as practicable following the effective date of the Registration Statement, establish a record date for, duly call, give notice of, convene and hold a special meeting of its stockholders (the “Parent Stockholder Meeting”) for the purpose of obtaining the Parent Stockholder Approval. Subject to Section 5.3(f), Parent shall, through the Parent Board, recommend to its stockholders approval of the Parent Stock Issuance and adoption of the Charter Amendment (the “Parent Board Recommendation”) and shall not (i) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to WPZ, such recommendation or (ii) fail to include such Parent Board Recommendation in the Parent Proxy Statement (any such action being referred to herein as a “Parent Adverse Recommendation Change”). Subject to Section 5.3(f), Parent shall use reasonable best efforts to obtain from its stockholders the Parent Stockholder Approval. Without limiting the generality of the foregoing, the obligations of Parent set forth in the first sentence of this Section 5.3(e) shall not be affected by a Parent Adverse Recommendation Change. Notwithstanding anything in this Agreement to the contrary, Parent may postpone or adjourn the Parent Stockholder Meeting (i) to solicit additional proxies for the purpose of obtaining the Parent Stockholder Approval, (ii) in the absence of quorum, (iii) if Parent has delivered any notice contemplated by Section 5.3(f) and the time periods contemplated by Section 5.3(f) have not expired, or (iv) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that Parent has determined after consultation with outside legal counsel is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the stockholders of Parent prior to the Parent Stockholder Meeting.

(f) Notwithstanding anything to the contrary in this Agreement, at any time prior to obtaining the Parent Stockholder Approval, and subject to compliance with the provisions of this Section 5.3(f), the Parent Board may, if the Parent Board determines in good faith (after consultation with the Parent’s financial advisor and outside legal counsel) that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties to stockholders under applicable Law, make a Parent Adverse Recommendation Change; provided, however, that no such Parent Adverse Recommendation Change shall be made in response to a Parent Acquisition Proposal that does not constitute a Parent Designated Proposal; provided further, however, that the Parent Board may not effect a Parent Adverse Recommendation Change pursuant to the foregoing unless:

(i) Parent has provided prior written notice to WPZ specifying in reasonable detail the reasons for such action (including, in the case of a Parent Designated Proposal, a description of the material terms of such Parent Designated Proposal) at least three (3) days in advance of its intention to take such action with respect to a Parent Adverse Recommendation Change, unless at the time such notice is required to be given there are less than three (3) days prior to the Parent Stockholder Meeting, in which case the Parent shall provide as much notice as is reasonably practicable (the period inclusive of all such days, the “Parent Notice Period”); and

(ii) during the Parent Notice Period the Parent Board has negotiated, and has used reasonable best efforts to cause its financial advisor and outside legal counsel to negotiate, with WPZ in good faith (to the extent WPZ desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the failure to effect such Parent Adverse Recommendation Change would not be reasonably likely to be inconsistent with its fiduciary duties to stockholders under applicable Law; provided that any material amendment to the terms of a Parent Designated Proposal, if applicable, shall require a new notice pursuant to this Section 5.3(f) and a new Parent Notice Period, except that such new Parent Notice Period in connection with any material amendment shall be for one business day from the time WPZ receives such notice (as opposed to three days).

(g) Unless this Agreement is validly terminated in accordance with Article VII, Parent shall submit the Parent Stock Issuance and adoption of the Charter Amendment for approval at the Parent Stockholder Meeting even if the Parent Board shall have effected a Parent Adverse Recommendation Change.

SECTION 5.4 Commercially Reasonable Efforts; Further Assurances. From and after the Execution Date, upon the terms and subject to the conditions hereof, each of the parties hereto shall use its commercially reasonable efforts to (i) take, or cause to be taken, all appropriate action, and to do or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the transactions contemplated by this Agreement as promptly as practicable and (ii) defend any lawsuits or other Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated by this Agreement or seek to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby, including the Merger. Without limiting the foregoing but subject to the

other terms of this Agreement, the parties hereto agree that, from time to time, whether before, at or after the Closing Date, each of them will execute and deliver, or cause to be executed and delivered, such instruments of assignment, transfer, conveyance, endorsement, direction or authorization as may be necessary to consummate and make effective the transactions contemplated by this Agreement. Notwithstanding the foregoing, nothing in this Agreement will require any party hereto to hold separate or make any divestiture not expressly contemplated herein of any asset or otherwise agree to any restriction on its operations or other condition in order to obtain any consent or approval or other clearance required by this Agreement.

SECTION 5.5 No Public Announcement. On the Execution Date, Parent and WPZ shall issue a joint press release with respect to the execution of this Agreement and the Merger, which press release shall be reasonably satisfactory to Parent and WPZ General Partner. From and after the Execution Date, neither WPZ nor Parent shall issue any other press release or make any other public announcement concerning this Agreement or the transactions contemplated by this Agreement (to the extent not previously issued or made in accordance with this Agreement) (other than public announcements at industry road shows and conferences or as may be required by applicable Law or by obligations pursuant to any listing agreement with the NYSE, in which event the party making the public announcement or press release shall, to the extent practicable, notify Parent and WPZ General Partner in advance of such public announcement or press release) without the prior approval of Parent and WPZ General Partner, which approval shall not be unreasonably withheld, delayed or conditioned.

SECTION 5.6 Expenses. Whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement, including legal fees, accounting fees, financial advisory fees and other professional and non-professional fees and expenses, shall be paid by the party hereto incurring such expenses, except that Parent and WPZ shall each pay for one-half of (a) any filing fees with respect to the Registration Statement and the Consent Statement/Prospectus/Parent Proxy Statement and (b) the costs of printing and mailing of the Consent Statement/Prospectus/Parent Proxy Statement.

SECTION 5.7 Regulatory Issues. WPZ and Parent shall cooperate fully with respect to any filing, submission or communication with a Governmental Entity having jurisdiction over the Merger. Such cooperation shall include each of the parties hereto: (i) providing, in the case of oral communications with a Governmental Entity, advance notice of any such communication and, to the extent permitted by applicable Law, an opportunity for the other party to participate; (ii) providing, in the case of written communications, an opportunity for the other party to comment on any such communication and provide the other with a final copy of all such communications; and (iii) complying promptly with any request for information from a Governmental Entity (including an additional request for information and documentary material), unless directed not to do so by the other party hereto. All cooperation shall be conducted in such a manner so as to preserve all applicable privileges.

SECTION 5.8 Tax Matters. For U.S. federal income tax purposes (and for purposes of any applicable state, local or foreign Tax that follows the U.S. federal income tax treatment), the parties agree to treat the Merger (a) with respect to holders of WPZ Public Units, as a taxable sale of such WPZ Common Units to Parent and (b) with respect to Parent, as a purchase of WPZ Public Units from the Holders of such WPZ Common Units. The parties will prepare and file all

Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return, or during the course of any audit, litigation or other proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the relevant Governmental Entity.

SECTION 5.9 D&O Insurance.

(a) For a period of six years after the Effective Time, Parent shall, and shall cause the WPZ Group Entities to, honor all rights to indemnification, advancement of expenses, elimination of liability and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement) now existing in favor of the WPZ D&O Indemnified Parties as provided in the Governing Documents of any WPZ Group Entity, under applicable Delaware Law or otherwise, and shall ensure that the Governing Documents of WPZ and WPZ General Partner (or their successor entities) shall, for a period of six years following the Effective Time, contain provisions substantially no less advantageous with respect to indemnification, advancement of expenses, elimination of liability and exculpation of their present and former directors, officers, employees and agents than are set forth in the Governing Documents of WPZ and WPZ General Partner as of the Execution Date.

(b) For a period of six years after the Effective Time, Parent shall maintain officers’ and directors’ liability insurance with a nationally reputable carrier covering each WPZ D&O Indemnified Party who is or at any time prior to the Effective Time was covered by the existing officers’ and directors’ liability insurance applicable to the WPZ Group Entities (“D&O Insurance”), on terms substantially no less advantageous to the WPZ D&O Indemnified Parties, as applicable, than such existing insurance with respect to acts or omissions, or alleged acts or omissions, prior to the Effective Time (whether claims, actions or other Proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time); provided, however, that Parent shall not be required to pay an annual premium for the D&O Insurance for the WPZ D&O Indemnified Parties in excess of 300% of the current annual premium currently paid by the WPZ Group Entities for such insurance, but shall purchase as much of such coverage as possible for such applicable amount. Parent shall have the right to cause such coverage to be extended under the applicable D&O Insurance by obtaining a six-year “tail” policy on terms and conditions no less advantageous to the WPZ D&O Indemnified Parties than the existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 5.9.

(c) The provisions of this Section 5.9 shall survive the consummation of the Merger and the other transactions contemplated by this Agreement for a period of six years and expressly are intended to benefit each of the WPZ D&O Indemnified Parties; provided, however, that in the event that any claim or claims for indemnification or advancement set forth in this Section 5.9 are asserted or made within such six-year period, all rights to indemnification and advancement in respect of any such claim or claims shall continue until disposition of all such claims. The rights of any WPZ D&O Indemnified Party under this Section 5.9 shall be in addition to any other rights such WPZ D&O Indemnified Party may have under the Governing Documents of any WPZ Group Entity or applicable Law.

(d) In the event Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, Parent shall cause proper provision to be made so that its successors and assigns, as the case may be, shall assume the obligations set forth in this Section 5.9.

SECTION 5.10 Dividends and Distributions. After the Execution Date until the Effective Time, each of Parent and WPZ shall coordinate with the other regarding the declaration of any dividends or distributions in respect of Parent Common Stock and WPZ Common Units and the record dates and payment dates relating thereto, it being the intention of the parties that Holders of WPZ Common Units shall not receive, for any quarter, distributions both in respect of WPZ Common Units and also dividends in respect of the Parent Common Stock that they receive in exchange therefor in the Merger, but that they shall receive for any such quarter (exclusive of any dividends received in respect of Parent Common Stock not received by such Holders in the Merger) either: (a) only distributions in respect of WPZ Common Units or (b) only dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger.

SECTION 5.11 Consent to Use of Financial Statements; Financing Cooperation. The WPZ Parties hereby consent to the Parent Group Entities’ use of and reliance on any audited or unaudited financial statements, including the WPZ Financial Statements, relating to the WPZ Group Entities reasonably requested by the Parent Parties to be used in any financing or other activities of the Parent Parties permitted hereby, including any filings that the Parent Parties desire to make with the SEC. In addition, the WPZ Parties will use commercially reasonable efforts, at the Parent Parties’ sole cost and expense, to obtain the consents of Ernst & Young LLP (with respect to certain consolidated financial statements of WPZ) and PricewaterhouseCoopers LLP (with respect to certain consolidated financial statements of WPZ) and Deloitte & Touche LLP (with respect to the financial statements of Gulfstream Natural Gas System, L.L.C.) to the inclusion of the financial statements referenced above in appropriate filings with the SEC. Prior to the Closing, the WPZ Parties will provide the Parent Parties such information, and make available such personnel, as the Parent Parties may reasonably request in order to assist any of the Parent Group Entities in connection with financing activities permitted hereby, including any public offerings to be registered under the Securities Act or private offerings.

SECTION 5.12 Section 16 Matters. Prior to the Effective Time, the WPZ Board and the Parent Board shall take all such steps as may be necessary or appropriate to cause the transactions contemplated by this Agreement, including any dispositions of WPZ Units (including derivative securities with respect to such WPZ Units) or acquisitions of shares of Parent Common Stock (including derivative securities with respect to such shares Parent Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to WPZ, or will become subject to such reporting requirements with respect to Parent, to be exempt under Rule 16b-3 promulgated under the Exchange Act.

SECTION 5.13 Conflicts Committee. Prior to the Effective Time, none of the WPZ Group Entities shall, without the consent of the WPZ Conflicts Committee, eliminate the WPZ

Conflicts Committee, or revoke or diminish the authority of the WPZ Conflicts Committee, or remove or cause the removal of any director of the WPZ Board that is a member of the WPZ Conflicts Committee either as a member of such board or such committee without the affirmative vote of the members of the WPZ Board, including the affirmative vote of each of the other members of the WPZ Conflicts Committee. For the avoidance of doubt, this Section 5.13 shall not apply to the filling in accordance with the provisions of the applicable Governing Documents of any vacancies caused by the death, incapacity or resignation of any director.

be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, provided such party is not in material default hereunder. Such remedies will not be the exclusive remedies for any breach of this Agreement but will be in addition to all other remedies available at law or equity to each of the parties.

SECTION 7.9 No Waiver Relating to Claims for Fraud/Willful Misconduct. The liability of any party under this Article VII shall be in addition to, and not exclusive of, any other liability that such party may have at law or in equity based on such party’s (a) fraudulent acts or omissions or (b) willful misconduct. None of the provisions set forth in this Agreement shall be deemed to be a waiver by or release of any party of any right or remedy that such party may have at law or equity based on any other party’s fraudulent acts or omissions or willful misconduct nor shall any such provisions limit, or be deemed to limit, (i) the amounts of recovery sought or awarded in any such claim for fraud or willful misconduct, (ii) the time period during which a claim for fraud or willful misconduct may be brought, or (iii) the recourse that any such party may seek against another party with respect to a claim for fraud or willful misconduct.

SECTION 8.2 Governing Law; Jurisdiction; Waiver of Jury Trial. To the maximum extent permitted by applicable Law, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without regard to principles of conflicts of law. Each of the parties hereto agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708. Each of the parties hereto irrevocably and unconditionally confirms and agrees that it is and shall continue to be (a) subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (b) subject to service of process in the State of Delaware. Each party hereto hereby irrevocably and unconditionally (i) consents and submits to the exclusive personal jurisdiction and venue of the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery declines to accept jurisdiction over any matter, any federal or state court located in the State of Delaware) (the “Delaware Courts”) for any actions, suits or proceedings arising out of or relating to this Agreement or the transactions contemplated by this Agreement (and agrees not to commence any litigation relating thereto except in such

courts), (ii) waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum, (c) acknowledges and agrees that any controversy that may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such party hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation directly or indirectly arising or relating to this Agreement or the transactions contemplated by this Agreement, and (d) agrees to service of process upon such party in any such action or proceeding shall be effective if such process is given as a notice in accordance with Section 8.1 or in any manner prescribed by the Laws of the State of Delaware. Nothing in this Section 8.2 shall affect the right of any party to serve legal process in any other manner permitted by Law.

SECTION 8.3 Entire Agreement; Amendments, Consents and Waivers. This Agreement, the Support Agreement, the Confidentiality Agreement and the exhibits and schedules hereto and thereto constitute the entire agreement between and among the parties hereto pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties, and there are no warranties, representations or other agreements between or among the parties in connection with the subject matter hereof except as set forth specifically herein or contemplated hereby. Except as expressly set forth in this Agreement (including the representations and warranties set forth in Articles III and IV), (a) the parties acknowledge and agree that neither the WPZ Group Entities nor any other Person has made, and the Parent Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the WPZ Group Entities or as to the accuracy or completeness of any information regarding any WPZ Group Entity furnished or made available to any Parent Group Entity, (b) the parties hereto acknowledge and agree that, except as set forth in this Agreement, neither the Parent Group Entities nor any other Person has made, and the WPZ Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the Parent Group Entities or as to the accuracy or completeness of any information regarding any Parent Group Entity furnished or made available to any WPZ Group Entity, and (c) the WPZ Parties and the Parent Parties shall not have or be subject to any liability to any Parent Group Entity or any other Person or any WPZ Group Entity or any other Person, as applicable, or any other remedy in connection herewith, based upon the distribution to any Parent Group Entity or any WPZ Group Entity of, or any Parent Group Entity’s or any WPZ Group Entity’s use of or reliance on, any such information or any information, documents or material made available to the Parent Group Parties or WPZ Group Parties, as applicable, in any “data rooms,” “virtual data rooms,” management presentations or in any other form in expectation of, or in connection with, the transactions contemplated hereby. Subject to compliance with applicable Law, prior to the Closing, any provision of this Agreement may be (a) consented to or waived in writing by the party benefited by the provision or (b) amended or modified at any time by an agreement in writing by the parties hereto; provided, however, that, in addition to any other approvals required by the WPZ Parties’ constituent documents or under this Agreement, the foregoing consents, waivers, amendments or modifications in clauses (a) and (b), and any decision or determination by WPZ to (x) terminate this Agreement pursuant to Section 7.2 or Section 7.3 or (y) enforce this Agreement (including pursuant to Section 7.8), must be approved by, in the case of consents, waivers, amendments or modifications, or such decisions or determinations, by any WPZ Party or the WPZ Board, the WPZ Conflicts Committee. No amendment, supplement, modification or waiver of this

Agreement shall be binding unless executed in writing by the parties hereto. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

SECTION 8.4 Binding Effect; No Third-Party Beneficiaries; and Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto and their respective permitted successors and assigns, any rights, benefits or obligations hereunder, except (i) as provided in Section 5.9 and (ii) for the right of the Holders of WPZ Units to receive the Merger Consideration (including any Fractional Share Payment) after the Closing (a claim by the Holders of WPZ Units with respect to which may not be made unless and until the Closing shall have occurred). No party hereto may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or alienation in violation of this Agreement shall be null, void and ineffective.

SECTION 8.5 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any matter materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.

SECTION 8.6 Counterparts. This Agreement may be executed in multiple counterparts each of which shall be deemed an original and all of which shall constitute one instrument.
