Section 2. Purchase of the Shares by the Underwriters.

On the basis of the representations and warranties contained in and subject to the terms and conditions of this Agreement, the Company agrees to sell the Firm Shares to the several Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase the number of Firm Shares set forth opposite that Underwriter’s name in Schedule 1 hereto. The respective purchase obligations of the Underwriters with respect to the Firm Shares shall be rounded among the Underwriters to avoid fractional Shares as the Representatives may determine.

In addition, the Company grants to the Underwriters an option to purchase up to 3,900,000 shares of Common Stock, severally and not jointly. Such option (the “Option”) is exercisable in the event that the Underwriters sell more Shares than the number of Firm Shares in the offering and as set forth in Section 4 hereof. Each Underwriter agrees, severally and not jointly, to purchase the number of Option Shares (subject to such adjustments to eliminate fractional Shares as the Representatives may determine) that bears the same proportion to the total number of Option Shares to be sold on such Delivery Date as the number of Firm Shares set forth in Schedule 1 hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

The price of both the Firm Shares and any Option Shares shall be $29.6723 per Share.

The Company shall not be obligated to deliver any of the Shares to be delivered on any Delivery Date, except upon payment for all the Shares to be purchased on such Delivery Date as provided herein.

Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder.

The Option granted in Section 2 will expire 30 days after the date of this Agreement and may be exercised in whole or in part from time to time by written notice being given to the Company by the Representatives; provided that if such date falls on a day that is not a business day, the Option granted in Section 2 will expire on the next succeeding business day. Such notice shall set forth the aggregate number of Option Shares as to which the Option is being exercised, the names in which the Option Shares are to be registered, the denominations in which the Option Shares are to be issued and the date and time, as determined by the Representatives, when the Option Shares are to be delivered; provided, however, that this date and time shall not be earlier than the First Delivery Date nor earlier than the second business day after the date on which the Option shall have been exercised nor later than the fifth business day after the date on which the Option shall have been exercised. The date and time the Option Shares are delivered is herein called a “Second Delivery Date” and the First Delivery Date and any Second Delivery Date are each herein called a “Delivery Date.”

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under Sections 8(a) and 8(b) except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under Sections 8(a) and 8(b). If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ separate counsel and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified party on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would present such counsel with a conflict of interest. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party,

contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Shares purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand, bear to the total gross proceeds from the offering of the Shares under this Agreement, as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the underwriting discount or commission applicable to the Shares purchased by such Underwriter hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Company acknowledge that the second full paragraph under the heading “Commissions and Expenses,” and the first full paragraph and the last sentence of the second paragraph under the heading “Stabilization, Short Positions and Penalty Bids,” each appearing under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

Section 9. Defaulting Underwriters.

If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Shares which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of the Firm Shares set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Firm Shares set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Shares on such Delivery Date if the total number of the Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Shares to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Shares which it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Shares to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Shares that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Option Shares) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases Firm Shares that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Shares of a defaulting or withdrawing Underwriter, either the Representatives or the Company, as the case may be, may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, any Preliminary Prospectus or the Prospectus or in any other document or arrangement.

Section 10. Termination.

The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Firm Shares if, prior to that time, any of the events described in Sections 7(j), 7(k) or 7(l), shall have occurred or if the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement.

Section 11. Reimbursement of Underwriters’ Expenses.

If the Company shall fail to tender the Shares for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company agrees to reimburse the Underwriters severally through the Representatives on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Underwriters severally in connection with this Agreement and the proposed purchase of the Shares (the “Expenses”). If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, the Company shall not be obligated to reimburse any defaulting Underwriter on account of those Expenses. If this agreement is terminated pursuant to Section 10 because any of the events described in Section 7(l) shall have occurred, the Company will reimburse the Underwriters severally through the Representatives on demand for the Expenses.

Section 12. Research Analyst Independence.

In addition, the Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering of the Shares that differ from the views of their respective investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Company.

Section 13. No Fiduciary Duty.

The Company acknowledges and agrees that in connection with the offering of the Shares, the sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. Furthermore, the Company agrees that it is responsible for making its own judgments and decisions in connection with this offering. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

Section 14. USA Patriot Act.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.

Section 15. Notices.

Russo (fax no.: (303) ###-###-####) and confirmed at (303) ###-###-####).

Section 16. Successors.

This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors and the indemnified persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

Section 17. Survival.

Section 18. Definition of the Terms “Business Day” and “subsidiary”.

For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” and “affiliate” have their respective meaning set forth in Rule 405 of the Rules and Regulations.

Section 19. Applicable Law and Waiver of Jury Trial.

(a) THIS AGREEMENT IS GOVERNED BY THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICTS OF LAWS PROVISIONS THEREOF THAT WOULD APPLY THE LAWS OF ANY OTHER STATE. THE COMPANY AND THE UNDERWRITERS EACH WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY OR ON BEHALF OF EITHER PARTY WITH RESPECT TO ANY MATTER WHATSOEVER RELATING TO OR ARISING OUT OF THE TERMS OF THIS AGREEMENT AND THE OFFERING CONTEMPLATED HEREBY.

(b) The parties hereby irrevocably submit to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan in The City of New York in any action or proceeding arising out of or relating to the terms of this Agreement and the offering contemplated hereby, and the parties hereby irrevocably agree that all claims in respect of such action or proceeding may be heard and determined in such New York State or federal court. The parties hereby irrevocably waive, to the fullest extent that they may legally do so, the defense of an inconvenient forum to the maintenance of such action or proceeding and each party irrevocably consents to the service of any and all process in any action or proceeding by the mailing or delivery of copies of such process to it at the office of the party set forth under Notices herein.

J.P. Morgan Securities LLC

Deutsche Bank Securities Inc.

as Representatives of the Underwriters

named in Schedule 1 hereto

c/o Barclays Capital Inc.

745 Seventh Avenue

New York, New York 10019

Dear Sirs:

The undersigned understands that you and certain other firms propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by you and such other firms (the “Underwriters”) of shares of common stock, par value $1.00 per share (the “Common Stock”) of The Williams Companies Inc., a Delaware corporation (the “Company”), and that the Underwriters propose to reoffer the Common Stock to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Stock (including, without limitation, Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Stock that may be issued upon exercise of any option or warrant) or securities convertible into or exchangeable for Common Stock owned by the undersigned on the date of execution of this Lock-Up Letter Agreement or on the date of the completion of the Offering, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) cause to be filed a registration statement (other than any registration statement on Form S-8) with respect to the registration of any Common Stock or securities convertible, exercisable or exchangeable into Common Stock or any other securities of the Company or (4) publicly disclose the intention to do any of the foregoing for a period of 90 days after the date of the final Prospectus relating to the Offering (such 90 day period, the “Lock-Up Period”). The foregoing sentence shall not apply to (A) transactions for the purpose of covering tax liabilities arising from or related to the vesting during the Lock-Up Period of shares of, or options to purchase shares of, Common Stock awarded pursuant to the Company’s existing equity compensation plans, (B) transactions relating to the cashless exercise of options to

purchase shares of Common Stock awarded pursuant to the Company’s existing equity compensation plans, (C) transactions pursuant to 10b5-1 plans in existence on the date hereof, or (D) bona fide gifts, sales or other dispositions of any Common Stock that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any such transfer described in clause (D) above that (i) the transferee/donee agrees to be bound by the terms of the lock-up agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto, (ii) no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with such transfer or distribution (other than a filing on Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A) made after the expiration of the 90-day period referred to above), (iii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended, and the Exchange Act) to make, and shall agree to not voluntarily make, any public announcement of the transfer or disposition, and (iv) the undersigned notifies Barclays Capital Inc. at least two business days prior to the proposed transfer or disposition.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Company notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company and the Underwriters.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.
