SUBJECT TO COMPLETION, DATED AUGUST 3, 2010

PROPOSED MERGER — YOUR VOTE IS VERY IMPORTANT

The boards of directors of Halliburton Company, or Halliburton, and Boots & Coots, Inc., or Boots & Coots, have approved an agreement and plan of merger, or the merger agreement, pursuant to which Boots & Coots will be merged with and into Gradient, LLC, or Gradient, with Gradient surviving as a direct wholly owned subsidiary of Halliburton. We are sending this proxy statement/prospectus to you to ask you to vote in favor of a proposal to adopt the merger agreement and other matters.

Under the merger agreement, Boots & Coots stockholders may elect to receive consideration consisting of cash, shares of Halliburton common stock or a combination of both in exchange for their shares of Boots & Coots common stock, subject to a proration feature. Subject to modification in order to achieve the intended tax consequences of the merger, Boots & Coots stockholders electing to receive a mix of cash and stock consideration and non-electing stockholders will receive (1) $1.73 in cash and (2) a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $1.27 by the volume weighted average trading price of a share of Halliburton common stock during the five-day trading period ending on the second full trading day immediately prior to the effective date of the merger (referred to as the Halliburton five-day average price), for each share of Boots & Coots common stock they own. Subject to proration and as more fully described in this proxy statement/prospectus, (i) Boots & Coots stockholders electing to receive all cash will receive $3.00 for each share of Boots & Coots common stock they own and (ii) Boots & Coots stockholders electing to receive only Halliburton common stock will receive a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $3.00 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. However, Halliburton will not issue any fractional shares of its common stock in connection with the merger. For each fractional share that would otherwise be issued, Halliburton will pay cash (without interest) in an amount equal to the product of the fractional share and the Halliburton five-day average price. We anticipate that, immediately following completion of the merger, Boots & Coots stockholders that receive Halliburton common stock in the merger will own less than 1.0% of the outstanding shares of Halliburton common stock.

Halliburton’s common stock is listed on the New York Stock Exchange under the symbol “HAL.” Boots & Coots’ common stock is listed on the NYSE Amex under the symbol “WEL.”

In connection with the merger, Boots & Coots is holding a special meeting of its stockholders to consider and vote on the merger agreement and certain other matters.

Your vote is very important. At Boots & Coots’ special meeting, Boots & Coots stockholders will be asked to adopt the merger agreement. The merger agreement provides for, among other things, the merger of Boots & Coots with and into Gradient and the issuance of Halliburton common stock to Boots & Coots stockholders as part of the merger consideration.

This document is a prospectus relating to the shares of Halliburton common stock to be issued pursuant to the merger and a proxy statement for Boots & Coots to solicit proxies for its special meeting of stockholders.

For a discussion of certain significant matters that you should consider before voting on the proposed transaction, see “Risk Factors” beginning on page 27.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the Halliburton common stock to be issued pursuant to the merger or passed upon the adequacy or accuracy of this proxy statement/prospectus.

QUESTIONS AND ANSWERS ABOUT THE MERGER

The following are answers to common questions that you may have regarding the merger and the special meeting. Halliburton and Boots & Coots urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the annexes to, and the documents incorporated by reference in, this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 103.

In this proxy statement/prospectus, unless the context otherwise requires, “Halliburton” refers to Halliburton Company and its consolidated subsidiaries, “Gradient” refers to Gradient, LLC, a wholly owned subsidiary of Halliburton, “Boots & Coots” refers to Boots & Coots, Inc. and its consolidated subsidiaries, the “merger agreement” refers to the Agreement and Plan of Merger, dated April 9, 2010, by and among Halliburton, Gradient and Boots & Coots, a copy of which is attached as Annex A to this proxy statement/prospectus, and the “merger” refers to the merger of Boots & Coots with and into Gradient, as contemplated by the merger agreement.


Q:		Why am I receiving this document?

A:		Halliburton has agreed to acquire Boots & Coots by means of a merger of Boots & Coots with and into Gradient, with Gradient as the surviving entity. As a result of the merger, Boots & Coots will cease to exist and Halliburton will continue to own Gradient. In order to complete the merger, Boots & Coots stockholders must vote to adopt the merger agreement, and Boots & Coots is holding a special meeting of stockholders to obtain the required stockholder approval.

		Boots & Coots is delivering this document to you because it is a proxy statement being used by the Boots & Coots board of directors to solicit proxies of Boots & Coots stockholders in connection with the special meeting to adopt the merger agreement. In addition, this document is a prospectus being delivered to Boots & Coots stockholders because Halliburton is offering shares of its common stock to Boots & Coots stockholders in exchange for shares of Boots & Coots common stock in connection with the merger.

Q:		What will happen in the merger?

A:		In the merger, Boots & Coots will be merged with and into Gradient, with Gradient surviving as a direct wholly owned subsidiary of Halliburton. After the merger, the current stockholders of Halliburton and the current stockholders of Boots & Coots who receive shares of Halliburton common stock in the merger will be the stockholders of Halliburton and the business currently conducted by Boots & Coots will be conducted by Gradient.

Q:		What are holders of Boots & Coots common stock being asked to vote on?

A:		Holders of Boots & Coots common stock are being asked to:

		• adopt the merger agreement; and

		• approve the adjournment of the special meeting, if necessary or appropriate to permit the solicitation of additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement.

Q:		Why is my vote important?

A:		If you do not return your proxy card by mail or submit your proxy by telephone or over the Internet or vote in person at the special meeting, it may be difficult for Boots & Coots to obtain the necessary quorum to hold its special meeting.

		In addition, your failure to vote will have the same effect as a vote “against” adoption of the merger agreement. With respect to the proposal to adjourn the special meeting, if necessary or appropriate in order to solicit additional proxies, an abstention will have the same effect as a vote “against” the proposal. Boots & Coots’ board of directors recommends that Boots & Coots stockholders vote “FOR” the


		adoption of the merger agreement and “FOR” the adjournment of the Boots & Coots special meeting, if necessary or appropriate to permit further solicitation of proxies.

		No matter how many shares you own, you are encouraged to vote.

Q:		What will I receive in the merger in exchange for my shares of Boots & Coots common stock?

A:		Under the merger agreement, Boots & Coots stockholders may elect to receive consideration consisting of cash, shares of Halliburton common stock or a combination of both in exchange for their shares of Boots & Coots common stock, subject to a proration feature as described under “Terms of the Merger Agreement — Allocation of Merger Consideration.” Subject to modification in order to achieve the intended tax consequences of the merger, Boots & Coots stockholders electing to receive a mix of cash and stock consideration and non-electing stockholders will receive (1) $1.73 in cash and (2) a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $1.27 by the volume weighted average trading price of a share of Halliburton common stock during the five-day trading period ending on the second full trading day immediately prior to the effective date of the merger (referred to as the Halliburton five-day average price), for each share of Boots & Coots common stock they own. Subject to proration, (i) Boots & Coots stockholders electing to receive all cash will receive $3.00 for each share of Boots & Coots common stock they own and (ii) Boots & Coots stockholders electing to receive only Halliburton common stock will receive a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $3.00 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. However, Halliburton will not issue any fractional shares of its common stock in connection with the merger. For each fractional share that would otherwise be issued, Halliburton will pay cash (without interest) in an amount equal to the product of the fractional share and the Halliburton five-day average price. We anticipate that, immediately following completion of the merger, Boots & Coots stockholders will own less than 1.0% of the outstanding shares of Halliburton common stock.


		For additional information regarding what Boots & Coots stockholders will be entitled to receive pursuant to the merger, see “Terms of the Merger Agreement — Per Share Merger Consideration” beginning on page 73.


Q:		Why is Boots & Coots proposing the merger?

A:		Boots & Coots believes that the merger will provide Boots & Coots’ stockholders with immediate cash liquidity, an opportunity for continued investment appreciation and other financial benefits, including:


		• a premium relative to the current and historical market price of Boots & Coots common stock represented by the proposed merger consideration of $3.00 per share which is: (i) 26% above the $2.38 closing price per share of Boots & Coots common stock on April 8, 2010, the business day prior to the date of the Boots & Coots board meeting to approve the merger; (ii) 86% above the $1.61 closing price per share of Boots & Coots common stock on January 27, 2010, the date Halliburton submitted its proposal letter to acquire all of the outstanding stock of Boots & Coots; and (iii) 107% above the $1.45 volume weighted average price per share of Boots & Coots common stock for the one year ended April 8, 2010;


		• the fact that the merger consideration per share of Boots & Coots common stock is generally fixed, with $1.73 payable in cash and $1.27 of Halliburton common stock valued based upon the Halliburton five day average price, which limits the exposure of Boots & Coots stockholders to fluctuations in the market price of Halliburton common stock;

		• Boots & Coots stockholders have the option to elect cash, Halliburton common stock or a mixture of cash and Halliburton common stock, subject to the proration features of the merger agreement; and

		• the Boots & Coots board of directors’ expectation that the merger will qualify as a tax free reorganization under the Internal Revenue Code of 1986, as amended (which is referred to as the Code in this proxy statement/prospectus), and that Boots & Coots stockholders may be eligible for tax free treatment on the Halliburton common stock, if any, they receive in the merger.


Q:		If I am a Boots & Coots stockholder, when must I elect the type of merger consideration that I prefer to receive?

A:		Holders of Boots & Coots common stock who wish to elect the type of merger consideration they prefer to receive pursuant to the merger should review and follow carefully the instructions set forth in the election form provided to Boots & Coots stockholders together with this proxy statement/prospectus or in a separate mailing. These instructions require that a properly completed and signed election form be received by the exchange agent by the election deadline, which is 5:00 p.m., New York time, on , 2010. If a Boots & Coots stockholder does not submit a properly completed and signed election form to the exchange agent by the election deadline, that stockholder will receive, in exchange for each Boots & Coots share, a mix of cash and stock consideration consisting of $1.73 in cash and a fraction of a share of Halliburton common stock equal to $1.27 divided by the Halliburton five-day average trading price (subject to modification in order to achieve the intended tax consequences of the merger).

Q:		What vote is required to approve the merger and related matters?

A:		The affirmative vote of a majority of shares of Boots & Coots common stock outstanding and entitled to vote at the special meeting is required to adopt the merger agreement and thereby approve the merger. At the close of business on , 2010, the record date for the special meeting, directors and executive officers of Boots & Coots and their respective affiliates had the right to vote % of the outstanding shares of Boots & Coots common stock. Each of Boots & Coots’ directors and executive officers has indicated his or her present intention to vote, or cause to be voted, the shares of Boots & Coots common stock owned by him or her for the adoption of the merger agreement.


		For additional information on the vote required to approve the merger and related matters, see “The Stockholder Meeting” beginning on page 33.


Q:		How does the Boots & Coots board of directors recommend that I vote with respect to the proposed merger?


A:		Boots & Coots’ board of directors recommends that the stockholders of Boots & Coots vote “FOR” the proposal to adopt the merger agreement. For additional information on the recommendation of Boots & Coots’ board of directors, see “The Merger — Reasons for the Merger — Boots & Coots” beginning on page 47.


		You should note that Boots & Coots’ directors and executive officers have interests in the merger as directors or officers that are different from, or in addition to, the interests of other Boots & Coots stockholders. For information relating to the interests of Boots & Coots’ directors and executive officers in the merger, see “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests” beginning on page 60.


Q:		What constitutes a quorum for the special meeting?

A:		A majority of the outstanding shares of Boots & Coots common stock entitled to vote at the close of business on the record date being present in person or by proxy constitutes a quorum for the special meeting.

Q:		When and where is the special meeting?

A:		The Boots & Coots special meeting will take place on , 2010 at , local time, at .


		For additional information relating to the Boots & Coots special meeting, see “The Stockholder Meeting” beginning on page 33.


Q:		Is the consummation of the merger subject to the approval of the stockholders of Halliburton?

A:		No. Halliburton stockholders are not required to adopt the merger agreement or approve the merger or the issuance of the shares of Halliburton common stock in connection with the merger.


Q:		Is the consummation of the merger subject to any conditions other than the approval of the stockholders of Boots & Coots?

A:		Yes. In addition to Boots & Coots stockholder approval, the consummation of the merger is contingent upon the following:

		• the absence of any statute, rule, order, decree or regulation that prohibits the consummation of the merger;

		• the registration statement that includes this prospectus becoming effective under the Securities Act of 1933, as amended, or the Securities Act, and not being the subject of any stop order or proceeding seeking a stop order;

		• the authorization for listing on the New York Stock Exchange, or the NYSE, of the shares of Halliburton common stock to be issued pursuant to the merger;

		• the receipt of tax opinions from counsel for each of Halliburton and Boots & Coots to the effect that the merger will qualify as a reorganization under Section 368(a) of the Code;

		• subject to certain exceptions, neither Mr. Jerry L. Winchester nor Mr. Dewitt H. Edwards ceasing to be employed by Boots & Coots or expressing any intention to terminate his employment or declining to accept employment with Halliburton; and

		• other customary conditions, including the absence of a material adverse effect on Halliburton or Boots & Coots.


		For additional information on the conditions to the consummation of the merger, see “Terms of the Merger Agreement — Conditions to the Merger” beginning on page 85.


Q:		What do I need to do now?

A:		After reading and considering carefully the information contained in this proxy statement/prospectus, please vote promptly by calling the toll-free number listed on your proxy card, accessing the Internet website listed on your proxy card or completing, signing, dating and returning your proxy card in the enclosed postage-paid envelope. If you hold your stock in “street name” through a bank or broker, you must direct your bank or broker to vote in accordance with the instructions you have received from your bank or broker. Submitting your proxy by telephone, Internet or mail or directing your bank or broker to vote your shares will ensure that your shares are represented and voted at the special meeting.


		For additional information on voting procedures, see “The Stockholder Meeting” beginning on page 33.


Q:		How will my proxy be voted?

A:		If you vote by telephone, over the Internet or by completing, signing, dating and returning your signed proxy card, your proxy will be voted in accordance with your instructions. The proxy confers discretionary authority to the named proxies. Accordingly, if you complete, sign, date and return your proxy card and do not indicate how you want to vote, your shares will be voted “FOR” the adoption of the merger agreement and “FOR” the adjournment of the Boots & Coots special meeting, if necessary or appropriate to permit further solicitation of proxies.


		For additional information on voting procedures, see “The Stockholder Meeting” beginning on page 33.


Q:		If my broker holds my shares in “street name,” will my broker automatically vote my shares for me?

A:		No. If you do not provide your broker with instructions on how to vote your “street name” shares, your broker will not be permitted to vote them on your behalf. Therefore, you should be sure to provide your broker with instructions on how to vote your shares, following the directions your broker provides to you. Please review the voting form used by your broker to see if the broker offers telephone or Internet voting.


Q:		What if I fail to instruct my broker?

A:		If you fail to instruct your broker to vote your shares and the broker submits an unvoted proxy, referred to as a broker non-vote, the broker non-vote will be counted toward a quorum at the special meeting, but effectively will be treated as a vote “against” the proposal to adopt the merger agreement, unless you appear and vote in person at the special meeting.


		For information on changing your vote if your shares are held in “street name,” see “The Stockholder Meeting” beginning on page 33.


Q:		What does it mean if I receive more than one set of materials?

A:		This means you own shares of Boots & Coots that are registered under different names. For example, you may own some shares directly as a stockholder of record and other shares through a broker, or you may own shares through more than one broker. In these situations, you will receive multiple sets of proxy materials. You must complete, sign, date and return all of the proxy cards or follow the instructions for any alternative voting procedures on each of the proxy cards you receive in order to vote all of the shares you own. Each proxy card you receive will come with its own postage-paid return envelope; if you vote by mail, make sure you return each proxy card in the return envelope that accompanied that proxy card.

Q:		What can I do if I want to change or revoke my vote?

A:		Regardless of the method you used to cast your vote, if you are a holder of record, you may change your vote:

		• by completing, signing, dating and returning a new proxy card with a later date so that it is received prior to the special meeting;


		• by calling the toll-free number listed on the proxy card or by accessing the Internet website listed on the proxy card by 11:59 p.m., New York time, on , 2010; or


		• by attending the special meeting and voting by ballot in person at the special meeting.


		You may also revoke your proxy card by sending a notice of revocation, which must be received prior to the special meeting, to the designated representative of Boots & Coots at the address provided under “Where You Can Find More Information” beginning on page 103. Your attendance at the special meeting will not, by itself, revoke any proxy that you have previously submitted.


		If you hold your shares in “street name” and wish to change or revoke your vote, please refer to the information on the voting instruction form included with these materials and forwarded to you by your bank, broker, custodian or other record holder to see your voting options.


		For additional information on changing your vote, see “The Stockholder Meeting” beginning on page 33.


Q:		Is the merger expected to be taxable to Boots & Coots stockholders?

A:		The merger is intended to qualify as a reorganization under Section 368(a) of the Code. It is a condition to closing of the merger that counsel for Halliburton and Boots & Coots deliver opinions to the effect that the merger will qualify as such a reorganization.

		Assuming that the merger qualifies as a reorganization and that you are a U.S. person:

		• if you receive solely Halliburton common stock in exchange for Boots & Coots common stock, then you generally will not recognize any gain or loss, except with respect to cash you receive in lieu of fractional shares of Halliburton common stock;

		• if you receive a combination of Halliburton common stock and cash in exchange for your Boots & Coots common stock, you may recognize gain, but any loss will not be currently recognized; and

		• if you receive solely cash in exchange for your Boots & Coots common stock, then you generally will recognize any gain or loss.


		You should read “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 91 for a description of the material U.S. federal income tax consequences of the merger. Tax matters can be complicated, and the tax consequences of the merger to you will depend on your particular situation. You should consult your tax advisor to determine the tax consequences of the merger to you.


Q:		What will happen to Boots & Coots’ stock options, stock appreciation rights and restricted stock in the merger?

A:		At the effective time of the merger, each outstanding option to purchase shares of Boots & Coots common stock and each stock appreciation right, or SAR, with respect to a share of Boots & Coots common stock, will fully vest and will be converted into an obligation of Gradient to pay the holder thereof an amount in cash equal to the product of (1) the number of shares of Boots & Coots common stock subject to the option or SAR, as applicable, and (2) the excess, if any, of $3.00 over the exercise price per share previously subject to such option or SAR.

		Immediately prior to the effective time of the merger, each outstanding award of restricted stock granted by Boots & Coots pursuant to an employee benefit plan will become fully vested, and each holder has the right to make the same elections as a holder of Boots & Coots common stock.


		For more information, see “Terms of the Merger Agreement — Stock Options, SARs and Restricted Shares” on page 75.


Q:		If I am a holder of Boots & Coots common stock with shares represented by stock certificates, should I send in my Boots & Coots stock certificates now?

A:		No. Please do not send in your Boots & Coots stock certificates with your proxy card. Rather, prior to the election deadline, send your completed, signed election form, together with your Boots & Coots common stock certificates (or a properly completed notice of guaranteed delivery) to the exchange agent identified in the election form. The election form for your Boots & Coots shares and your instructions will be delivered to you together with this proxy statement/prospectus or in a separate mailing.

Merger Consideration (Pages 73 and 74)

Under the merger agreement, Boots & Coots stockholders may elect to receive consideration consisting of cash, shares of Halliburton common stock or a combination of both in exchange for their shares of Boots & Coots common stock, subject to a proration feature described below. Subject to modification in order to achieve the intended tax consequences of the merger as discussed below, Boots & Coots stockholders electing to receive a mix of cash and stock consideration and non-electing stockholders will receive (1) $1.73 in cash and (2) a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $1.27 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. Subject to proration, (i) Boots & Coots stockholders electing to receive all cash will receive $3.00 for each share of Boots & Coots common stock they own and (ii) Boots & Coots stockholders electing to receive only Halliburton common stock will receive a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $3.00 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. For a more complete description of what Boots & Coots stockholders will be entitled to receive pursuant to the merger, see “Terms of the Merger Agreement — Per Share Merger Consideration” beginning on page 73.

Under the merger agreement, if and to the minimum extent necessary for Baker Botts L.L.P. and Thompson & Knight LLP to deliver their opinions to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the allocation of the total merger consideration to be paid in cash and Halliburton common stock will change. See “The Merger — Opinions as to Material U.S. Federal Income Tax Consequences of the Merger” on page 60. The value of $1.27, which is used to compute the exchange ratio for the stock portion of the total merger consideration, will be increased, and the $1.73 in cash to be paid per share of Boots & Coots common stock, will be correspondingly decreased, to the minimum extent necessary for the aggregate fair market value of all shares of Halliburton common stock that would be issued pursuant to the merger (valued as of the effective date of the merger), referred to as the “total stock value,” to constitute not less than 40% of the sum of the total stock consideration plus the total amount of cash paid to Boots & Coots stockholders pursuant to the merger, which sum is referred to as the “total merger value,” considering the following factors:


	•	for tax purposes, tax counsel will treat shares of Boots & Coots restricted stock that are exchanged for Halliburton common stock in the merger as having been exchanged for cash solely for purposes of computing the total stock value; and

	•	the fair market value of a share of Halliburton common stock is determined for tax purposes as of the effective date of the merger instead of using the Halliburton five-day average price.

See “Material U.S. Federal Income Tax Consequences of the Merger — Qualification of the Merger as a Reorganization and Tax Opinions” beginning on page 92. The minimum number of shares of Boots & Coots restricted stock that would need to be exchanged for Halliburton common stock in order to cause a reallocation of merger consideration will vary depending on the fair market value of a share of Halliburton common stock as of the effective date of the merger and the Halliburton five-day average price. For example, if the fair market value of a share of Halliburton common stock valued as of the effective date of the merger is equal to the Halliburton five-day average price, then a reallocation of the merger consideration would occur

if more than approximately 60.9% of the shares of Boots & Coots restricted stock are exchanged solely for Halliburton common stock in the merger, but if the fair market value of a share of Halliburton common stock valued as of the effective date of the merger is less than the Halliburton five-day average price, then the reallocation of the merger consideration may occur even if fewer than approximately 60.9% of the shares of Boots & Coots restricted stock are exchanged solely for Halliburton common stock in the merger. As a result of elections to be made by Messrs. Winchester and Edwards to receive only Halliburton common stock in the merger (see “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests — Change of Control Arrangements” beginning on page 63), as of July 27, 2010, 1,122,764 shares, or approximately 35.4% of all outstanding shares, of Boots & Coots restricted stock may be exchanged for Halliburton common stock but be treated as having been exchanged for cash solely for purposes of computing the total stock value. See “Material U.S. Federal Income Tax Consequences of the Merger — Qualification of the Merger as a Reorganization and Tax Opinions.” The reallocation of the merger consideration will, to the minimum extent necessary, have the effect of reducing the amount of cash paid to Boots & Coots stockholders, and correspondingly increasing the number of shares of Halliburton common stock issued to Boots & Coots stockholders.

Assuming no reallocation of the merger consideration, the aggregate cash consideration to be received by Boots & Coots stockholders pursuant to the merger will be fixed at an amount equal to the product of $1.73 and the number of issued and outstanding shares of Boots & Coots common stock immediately prior to closing of the merger, which cash amount is expected to be approximately $143.2 million based on the number of shares of Boots & Coots common stock and restricted stock outstanding as of July 27, 2010, excluding an estimated $4.9 million in cash payments to holders of Boots & Coots stock options and SARs. Accordingly, if Boots & Coots stockholders elect, in the aggregate, to receive cash in an amount greater than the aggregate cash consideration payable under the merger agreement, then the stockholders electing to receive all cash will be pro rated down and will receive Halliburton common stock as a portion of the overall consideration they receive for their shares. Similarly, if Boots & Coots stockholders elect, in the aggregate, to receive Halliburton common stock in an amount greater than the aggregate number of shares issuable under the merger agreement, then the holders electing to receive all stock consideration will be pro rated down and will receive cash as a portion of the overall consideration they receive for their shares. As a result, Boots & Coots stockholders that make a valid election to receive all cash or all stock consideration may not receive merger consideration entirely in the form elected. See “Risk Factors — Boots & Coots stockholders electing to receive only cash or only Halliburton common stock may receive a form or combination of consideration different from the form they elect” beginning on page 28.

Halliburton will not issue any fractional shares of its common stock in connection with the merger. For each fractional share that would otherwise be issued, Halliburton will pay cash (without interest) in an amount equal to the product of the fractional share and the Halliburton five-day average price. See “Terms of the Merger Agreement — Per Share Merger Consideration — Fractional Shares” on page 74.

Completion and Delivery of the Election Form (Page 75)

If you are a holder of record of Boots & Coots common stock at the close of business on , 2010, the record date for the special meeting, you have received or will receive (together with this proxy statement/prospectus or in a separate mailing) an election form with instructions for making cash and stock elections. You must properly complete and deliver to the exchange agent your election form along with your stock certificates (or a properly completed notice of guaranteed delivery). Do not send your stock certificates or election form with your proxy card.

Election forms and stock certificates (or a properly completed notice of guaranteed delivery) must be received by the exchange agent by the election deadline, which is 5:00 p.m., New York time, on , 2010. Once you tender your stock certificates to the exchange agent, you may not transfer your shares of Boots & Coots common stock until the merger is completed, unless you revoke your election by a written notice to the exchange agent that is received prior to the election deadline.

If you fail to submit a properly completed election form prior to the election deadline, you will be deemed not to have made an election. As a holder making no election, you will receive the mixed cash and stock consideration.

If you own shares of Boots & Coots common stock in “street name” through a broker or other nominee and you wish to make an election, you should seek instructions from the broker or other nominee holding your shares concerning how to make your election.

If the merger is not completed, stock certificates will be returned by the exchange agent by first class mail or through book-entry transfer (in the case of shares of Boots & Coots common stock delivered in book-entry form to the exchange agent).

Treatment of Stock Options, SARs and Restricted Stock (Page 75)

At the effective time of the merger, each outstanding option to purchase shares of Boots & Coots common stock and each outstanding SAR, whether or not then exercisable or vested, will be converted into an obligation of Gradient to pay the option or SAR holder an amount in cash equal to the product of (1) the number of shares of Boots & Coots common stock subject to the option or SAR, as applicable, and (2) the excess, if any, of $3.00 over the exercise price per share previously subject to such option or SAR.

Immediately prior to the effective time of the merger, each outstanding award of Boots & Coots restricted stock will become fully vested, and each holder has the right to make the same elections as a holder of Boots & Coots common stock.

Recommendation of the Boots & Coots Board of Directors (Page 33)

Boots & Coots’ board of directors has adopted a resolution approving the merger agreement, declared the merger agreement advisable and determined that the merger agreement and the transactions contemplated by it are fair to and in the best interests of Boots & Coots and its stockholders and recommends that Boots & Coots stockholders vote at the special meeting to adopt the merger agreement and approve any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies. See “The Merger — Background of the Merger” beginning on page 38. As described under the heading “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests” beginning on page 60 of this proxy statement/prospectus, Boots & Coots’ directors and executive officers will receive financial benefits that may be different from, or in addition to, those of Boots & Coots stockholders.

Opinion of Howard Frazier Barker Elliott, Inc.
(Page 53)

In deciding to recommend the merger, Boots & Coots considered an opinion from its financial advisor, Howard Frazier Barker Elliott, Inc., or HFBE. HFBE rendered its opinion to Boots & Coots’ board of directors that, as of April 9, 2010, based upon and subject to the qualifications, limitations and assumptions stated in its opinion, the merger consideration to be received by the stockholders of Boots & Coots was fair, from a financial point of view, to such stockholders.

The full text of the written opinion of HFBE, dated April 9, 2010, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex B to this proxy statement/prospectus. HFBE provided its opinion for the information and assistance of Boots & Coots’ board of directors in connection with its consideration of the merger. The HFBE opinion is not a recommendation as to how any holder of Boots & Coots common stock should vote with respect to the adoption of the merger agreement or any other matter.

Pursuant to a letter agreement dated February 24, 2010, Boots & Coots engaged HFBE to render an opinion to the Boots & Coots board of directors as to the fairness, from a financial point of view, of the consideration to be received by the Boots & Coots common stockholders in connection with the merger. As compensation for its services in connection with the merger, Boots & Coots paid HFBE $75,000 upon

execution of the letter agreement and $75,000 upon the delivery of HFBE’s fairness opinion. In addition, Boots & Coots has agreed to reimburse HFBE for its reasonable out-of-pocket expenses, including attorneys’ fees and disbursements, and to indemnify HFBE and related persons against various liabilities.

Board of Directors and Management of Halliburton Following the Merger
(Page 60)

Halliburton’s board of directors and executive officers will remain the same immediately following the merger as they were immediately before the merger becomes effective.

The Stockholder Meeting
(Page 33)

The Boots & Coots special meeting will be held for the following purposes:


	•	to consider and vote upon a proposal to adopt the merger agreement; and

	•	to consider and vote upon a proposal to adjourn the special meeting, if necessary or appropriate to solicit additional proxies in favor of the foregoing proposal.

Record Date
(Page 33)

You may vote at the special meeting of Boots & Coots stockholders if you owned Boots & Coots common stock at the close of business on , 2010, the record date for the special meeting.

Votes Required
(Page 34)

Boots & Coots. Each share of Boots & Coots common stock outstanding as of the record date is entitled to one vote at the Boots & Coots special meeting. Adoption of the merger agreement by Boots & Coots stockholders requires the affirmative vote of a majority of the outstanding shares of Boots & Coots common stock that are entitled to vote as of the record date. Any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies, requires the affirmative vote of the holders of Boots & Coots common stock representing a majority of the votes present in person or by proxy at the special meeting entitled to vote.

If a Boots & Coots stockholder abstains from voting, that action will be the equivalent of a vote “against” all of the matters to be voted upon. A broker non-vote will be the equivalent of a vote “against” adopting the merger agreement, but will have no effect on any vote to adjourn the special meeting, if necessary or appropriate to solicit additional proxies.

An abstention occurs when a stockholder abstains from voting (either in person or by proxy) on one or more of the proposals. Broker non-votes occur when a bank, broker or other nominee returns a proxy but does not have authority to vote on a particular proposal in its discretion and the beneficial owner of the shares has not provided voting instructions.

Halliburton. Halliburton stockholders are not required to adopt the merger agreement or approve the merger or the issuance of the shares of Halliburton common stock in connection with the merger.

Outstanding Shares and Share Ownership of Management
(Page 34)

As of the record date for the Boots & Coots special meeting, there were shares of Boots & Coots common stock outstanding. Directors and executive officers of Boots & Coots beneficially owned approximately % of the outstanding shares of Boots & Coots common stock on the record date.

Risks Relating to the Merger
(Page 27)

You should be aware of and consider carefully the risks relating to the merger described under “Risk Factors.” These risks include possible difficulties in Halliburton’s ability to integrate effectively the businesses of Halliburton and Boots & Coots, two companies that have previously operated independently.

Material U.S. Federal Income Tax Consequences of the Merger
(Page 91)

Halliburton and Boots & Coots each expect the merger to be a tax free reorganization pursuant to Section 368(a) of the Code and that Boots & Coots stockholders may be eligible for tax free treatment on the Halliburton common stock, if any, they receive in the merger.

Please review carefully the information under the caption “Material U.S. Federal Income Tax Consequences of the Merger” for a description of the material U.S. federal income tax consequences of the merger. The tax consequences to you will depend on your own situation. Please consult your tax advisor for a full understanding of the tax consequences of the merger to you.

Accounting Treatment
(Page 59)

Halliburton will account for the merger using the acquisition method of accounting under U.S. generally accepted accounting principles, or GAAP.

Appraisal Rights
(Page 66)

Boots & Coots stockholders will, under certain circumstances, be entitled under Delaware law to exercise appraisal rights and receive payment for the fair value of their Boots & Coots shares if the merger is completed. However, under Section 262 of the DGCL, appraisal rights are only available in connection with the merger if, among other things, holders of Boots & Coots stock are required to accept cash consideration for their Boots & Coots shares (other than cash paid in lieu of fractional shares). Accordingly, Halliburton reserves the right to take the position that appraisal rights are not available if, after application of the proration provisions of the merger agreement, all stockholders who elected to receive all stock consideration and all stockholders who demanded appraisal of their shares could have received consideration consisting of only Halliburton common stock and cash paid in lieu of receiving fractional shares of Halliburton common stock as a result of the merger. Boots & Coots stockholders who wish to seek appraisal of their shares are in any case urged to seek the advice of counsel with respect to the availability of appraisal rights.

If appraisal rights are available, Boots & Coots stockholders who desire to exercise their appraisal rights must not vote in favor of the adoption of the merger agreement, must submit a written demand for an appraisal before the vote on the adoption of the merger agreement and must continue to hold their Boots & Coots shares through the effective date of the merger. Boots & Coots stockholders must also comply with other procedures as required by Section 262 of the DGCL. If appraisal rights are available, Boots & Coots stockholders who validly demand appraisal of their shares in accordance with the DGCL and do not withdraw their demand or otherwise forfeit their appraisal rights will not receive the merger consideration. Instead, after

completion of the proposed merger, the Court of Chancery of the State of Delaware will determine the fair value of their shares exclusive of any value arising from the proposed merger. This appraisal amount will be paid in cash and could be more than, the same as or less than the amount a Boots & Coots stockholder would be entitled to receive under the merger agreement.

The DGCL requirements for exercising appraisal rights are described in further detail in this proxy statement/prospectus, and Section 262 of the DGCL regarding appraisal rights is reproduced and attached as Annex C to this proxy statement/prospectus.

Conditions to the Merger
(Page 85)

The merger will be completed only if the conditions to the merger are satisfied or waived (if legally permissible), including the following:


	•	the absence of any statute, rule, order, decree or regulation that prohibits the consummation of the merger;

	•	the registration statement that includes this prospectus becoming effective under the Securities Act and not being the subject of any stop order or proceeding seeking a stop order;

	•	the authorization for listing on the NYSE of the shares of Halliburton common stock to be issued pursuant to the merger;

	•	the receipt of tax opinions from counsel for each of Halliburton and Boots & Coots to the effect that the merger will qualify as a reorganization under Section 368(a) of the Code;

	•	subject to certain exceptions, neither Mr. Winchester nor Mr. Edwards ceasing to be employed by Boots & Coots or expressing any intention to terminate his employment or declining to accept employment with Halliburton; and

	•	other customary conditions, including the absence of a material adverse effect on Halliburton or Boots & Coots.

The parties to the merger agreement may choose to complete the merger even though a condition has not been satisfied if the law allows the parties to do so; however, neither Halliburton nor Boots & Coots can give any assurance regarding when or if all of the conditions to the merger will be either satisfied or waived or that the merger will occur as intended.

Regulatory Requirements
(Page 70)

The merger is subject to antitrust laws, including the Hart-Scott-Rodino Act, or HSR Act. On April 19, 2010, Halliburton and Boots & Coots made their respective filings under the HSR Act with the Antitrust Division of the United States Department of Justice, which is referred to as the Antitrust Division in this proxy statement/prospectus, and the United States Federal Trade Commission, which is referred to as the FTC in this proxy statement/prospectus. On April 29, 2010, the FTC granted early termination of the waiting period under the HSR Act.

Termination of the Merger Agreement
(Page 87)

Mutual Termination Rights. Halliburton and Boots & Coots can mutually agree to terminate the merger agreement at any time. Either Halliburton or Boots & Coots can unilaterally terminate the merger agreement in various circumstances, including the following:


	•	if the merger has not occurred on or before October 1, 2010 (December 1, 2010 if all conditions other than the termination or expiration of the waiting period under the HSR Act or any statute requiring premerger notification have been or are capable of being fulfilled), or the outside date, but neither party may terminate the merger agreement if that party’s failure to fulfill any material obligation under the merger agreement has caused or resulted in the failure of the merger to occur on or before the outside date;

	•	a governmental entity has issued a final, non-appealable statute, rule, order, decree or regulation or taken any other action, in each case permanently restraining, enjoining or otherwise prohibiting the merger, but neither party may terminate the merger agreement if its failure to fulfill any material obligation under the merger agreement has been the cause of or resulted in such action or if it materially breaches certain provisions of the merger agreement with respect to such action;

	•	the Boots & Coots stockholders have failed to adopt the merger agreement at the Boots & Coots special meeting; or

	•	if the other party has breached or failed to perform any representation, warranty or covenant in the merger agreement such that the conditions to the closing of the merger agreement related to the accuracy of the representations and warranties or the performance of the covenants of such other party would fail and that breach or failure is incapable of being cured prior to the outside date or is not cured within 30 days after notice of the breach or failure to perform, as long as the terminating party is not in material breach and has not materially failed to perform any of its representations, warranties or covenants in the merger agreement.

Boots & Coots’ Termination Rights. Boots & Coots may generally terminate the merger agreement if the Boots & Coots board of directors has effected a change in its recommendation and has authorized Boots & Coots to enter into an acquisition agreement in respect of a related superior proposal (as defined in “Terms of the Merger Agreement — Certain Additional Agreements”) and Boots & Coots has paid or concurrently pays $10.0 million to Halliburton.

Halliburton’s Termination Rights. Halliburton may terminate the merger agreement if:


	•	Boots & Coots has breached or failed to perform in any respect any of its covenants or other agreements in the merger agreement prohibiting it from, among other things, soliciting other acquisition proposals and requiring it to call and hold the Boots & Coots stockholder meeting;

	•	the Boots & Coots board of directors has effected a change in its recommendation or the Boots & Coots board of directors or any committee thereof has resolved to make such a change;


	•	Boots & Coots has recommended, adopted or approved, or proposed publicly to recommend, adopt or approve, any acquisition proposal (as defined in “Terms of the Merger Agreement — Certain Additional Agreements”) or acquisition agreement relating thereto;


	•	Boots & Coots has failed to reaffirm the recommendation of its board of directors that the Boots & Coots stockholders vote in favor of the adoption of the merger agreement within three business days following receipt from Halliburton of a written request for such reaffirmation; or

	•	within ten business days after a tender or exchange offer relating to securities of Boots & Coots has first been published or announced, Boots & Coots has not sent or given to its stockholders pursuant to Rule 14e-2 promulgated under the Securities Exchange Act of 1934, as amended, or the Exchange Act, a statement disclosing that its board of directors recommends rejection of such tender or exchange offer.

Termination Fee and Expense Reimbursement
(Page 88)

In connection with the termination of the merger agreement in certain circumstances involving a takeover proposal by a third party for Boots & Coots, a change of the Boots & Coots board of directors’ recommendation to the Boots & Coots stockholders to vote in favor of the approval of the merger agreement, or certain breaches of the merger agreement by Boots & Coots, Boots & Coots will be required to pay Halliburton a termination fee of $10.0 million.

Furthermore, either Halliburton or Boots & Coots will have to pay to the other party out-of-pocket expenses, including all fees and expenses payable to all legal, accounting, financial, public relations and other professional advisors arising out of, in connection with, or related to the merger, up to a maximum of $1.5 million in the aggregate, if the merger agreement is terminated under certain circumstances.

Interests of Certain Persons in the Merger that May be Different from Your Interests
(Page 60)

Boots & Coots’ directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of holders of Boots & Coots common stock. These interests include certain Boots & Coots executive officers being entitled to receive certain benefits in connection with the merger. Some of these benefits include the following:


	•	lump sum payments to executive officers of up to approximately $3.7 million in the aggregate in exchange for the termination and waiver of substantially all of those executive officers’ rights under their current arrangements with Boots & Coots;

	•	the accelerated vesting of Boots & Coots SARs and options to purchase shares of Boots & Coots common stock held by Boots & Coots’ directors and executive officers at the effective time of the merger and the right to receive a cash payment in respect of such SARs and options;

	•	the accelerated vesting of Boots & Coots restricted stock held by Boots & Coots’ directors and executive officers at the effective time of the merger and the right to receive the merger consideration in respect of that restricted stock; and

	•	positions with Halliburton that Boots & Coots executive officers are expected to hold upon completion of the merger, including Messrs. Winchester’s and Edwards’ roles in managing Boots & Coots’ business.

Boots & Coots’ board of directors was aware of these interests and considered them, among other matters, in making its recommendation that Boots & Coots stockholders vote in favor of the adoption of the merger agreement. See “The Merger — Reasons for the Merger — Boots & Coots” beginning on page 47.

Acquisition Proposals
(Page 81)

Boots & Coots and its subsidiaries will not, and Boots & Coots and its subsidiaries will cause their respective officers, directors, investment bankers, attorneys, accountants, financial advisors, agents and other representatives not to, (1) directly or indirectly, initiate, solicit or encourage or take any action to facilitate an acquisition proposal, (2) directly or indirectly, participate or engage in discussions or negotiations with or disclose any non-public information to any other party with respect to an acquisition proposal, (3) accept an acquisition proposal or (4) enter into any agreement relating to an acquisition proposal. However, prior to the time Boots & Coots’ stockholders approve the merger agreement, Boots & Coots or its board of directors may take any action described in clause (2) above if Boots & Coots receives a bona fide unsolicited written acquisition proposal from a third party and, among other things,


	•	Boots & Coots’ board of directors determines in good faith after consultation with financial advisors and outside legal counsel that:


	•	the proposal constitutes or is reasonably likely to result in a transaction more favorable to its stockholders than the merger and is reasonably likely to be completed on the terms proposed; and

	•	the third party has the financial and legal capability to consummate that proposal; and

Recent Developments

The Gulf of Mexico/Macondo Well Incident

The semisubmersible drilling rig, Deepwater Horizon, sank on April 22, 2010 after an explosion and fire onboard the rig that began on April 20, 2010. The Deepwater Horizon was owned by Transocean Ltd. and had been drilling the Macondo/MC252 exploration well in Mississippi Canyon Block 252 in the Gulf of Mexico for the lease operator, BP Exploration & Production, Inc. (“BP Exploration”), an indirect wholly owned subsidiary of BP p.l.c. Crude oil flowing from the well site has spread across thousands of square miles of the Gulf of Mexico and has reached the United States Gulf Coast. Efforts to contain the flow of hydrocarbons from the well are being led by the United States government and by BP p.l.c., BP Exploration, and their affiliates (collectively, “BP”). In addition, there were eleven fatalities and a number of injuries as a result of the Macondo Well incident. The cause of the explosion, fire, and resulting oil spill is being investigated by numerous industry participants, governmental agencies, and Congressional committees.

Halliburton performed a variety of services on the Macondo well, including cementing, mud logging, directional drilling, measurement-while-drilling, and rig data acquisition services. Halliburton had completed the cementing of the final production casing string in accordance with BP Exploration’s requirements approximately 20 hours prior to the Macondo Well incident. Halliburton believes that it performed all such work in accordance with BP Exploration’s specifications for BP Exploration’s well construction plan and BP Exploration’s instructions.

Investigations

The United States Department of Homeland Security and Department of the Interior have begun a joint investigation into the cause of the Macondo Well incident. The United States Coast Guard, a component of the United States Department of Homeland Security, and the Bureau of Ocean Energy Management, Regulation, and Enforcement (“BOE”) (formerly known as the Minerals Management Service), a bureau of the United States Department of the Interior, share jurisdiction over the investigation into the Macondo Well incident. In addition, another investigation has been commenced by the Chemical Safety Board, and the President of the United States has established the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling to, among other things, examine the relevant facts and circumstances concerning the causes of the Macondo Well incident and develop options for guarding against future oil spills associated with offshore drilling. Halliburton is assisting in efforts to identify the factors that led to the Macondo Well incident and has participated and will continue to participate in various hearings relating to the incident held by, among others, various committees and subcommittees of the House of Representatives and the Senate of the United States.

On May 28, 2010, the United States Department of the Interior issued an order imposing a six month suspension on all offshore deepwater drilling projects. A preliminary injunction was issued blocking enforcement of the deepwater drilling suspension on June 22, 2010, and the Department of the Interior issued a new suspension of deepwater drilling on July 12, 2010.

On June 1, 2010, the United States Attorney General announced that the United States Department of Justice (“DOJ”) was launching civil and criminal investigations into the Macondo Well incident to closely examine the actions of those involved, and that the DOJ was working with attorneys general of states affected by the Macondo Well incident. The DOJ announced that it is reviewing, among other traditional criminal statutes, The Clean Water Act, which carries civil penalties and fines as well as criminal penalties, The Oil Pollution Act of 1990, which can be used to hold parties liable for cleanup costs and reimbursement for government efforts, and The Migratory Bird Treaty Act of 1918 and Endangered Species Act of 1973, which provide penalties for injury and death to wildlife and bird species.

Furthermore, in June 2010, Halliburton received a letter from the DOJ requesting thirty days advance notice of any event that may involve substantial transfers of cash or other corporate assets outside of the ordinary course of business. In Halliburton’s reply to the June 2010 DOJ letter, Halliburton conveyed its interest in briefing the DOJ on the services Halliburton provided on the Deepwater Horizon but indicated that Halliburton could not bind itself to requests that have no demonstrated basis in law or fact.

Halliburton intends to cooperate fully with all governmental hearings, investigations, and requests for information relating to the Macondo Well incident.

Litigation

Currently, Halliburton has been named along with other unaffiliated defendants in more than 270 class-action complaints involving pollution damage claims and in 15 suits involving multiple plaintiffs that allege wrongful death and other personal injuries arising out of the Macondo Well incident. The pollution damage complaints generally allege, among other things, negligence and gross negligence, property damages, and potential economic losses as a result of environmental pollution and generally seek awards of unspecified economic, compensatory, and punitive damages, as well as injunctive relief. The wrongful death and other personal injury complaints generally allege negligence and gross negligence and seek awards of compensatory damages, including unspecified economic damages and punitive damages. Halliburton has retained counsel and is investigating and evaluating the claims, the theories of recovery, damages asserted, and its respective defenses to all of these claims. Halliburton intends to vigorously defend any litigation, fines, and/or penalties relating to the Macondo Well incident. Additional lawsuits may be filed against Halliburton.

Indemnification and Insurance

Halliburton’s contract with BP Exploration relating to the Macondo well provides for Halliburton’s indemnification for potential claims and expenses relating to the Macondo Well incident, including those

resulting from pollution or contamination (other than claims by Halliburton’s employees, loss or damage to Halliburton’s property, and any pollution emanating directly from Halliburton’s equipment). Also, under Halliburton’s contract with BP Exploration, Halliburton has, among other things, generally agreed to indemnify BP Exploration and other contractors performing work on the well for claims for personal injury of Halliburton’s employees and subcontractors, as well as for damage to Halliburton’s property. In turn, Halliburton believes that BP’s other contractors performing work on the well have agreed in their contracts with BP to indemnify Halliburton for claims for personal injury of their employees or subcontractors as well as for damages to their property. Halliburton believes that the indemnification obligations contained in its contract are valid and binding against BP Exploration. BP Exploration contractually assumed responsibility for costs and expenses relating to this event, including claims for gross negligence. Given the potential amounts involved, however, BP Exploration and other indemnifying parties may seek to avoid their indemnification obligations. In particular, while Halliburton does not believe there is any justification to do so, BP Exploration, in response to Halliburton’s request for indemnification, has generally reserved all of its rights and stated that it is premature to conclude that it is obligated to indemnify Halliburton. In doing so, BP Exploration has asserted that the facts are not sufficiently developed to determine who is responsible, and have cited a variety of possible legal theories based upon the contract and facts still to be developed. In addition, the financial analysts and the press have speculated about the financial capacity of BP and whether BP might seek to avoid indemnification obligations in bankruptcy. Halliburton considers the likelihood of a BP bankruptcy to be remote.

In addition to the contractual indemnity, Halliburton has a general liability insurance program of $600 million. Halliburton’s insurance is designed to cover claims by businesses and individuals made against Halliburton in the event of property damage, injury or death and, among other things, claims relating to environmental damage. To the extent Halliburton incurs any losses beyond those covered by indemnification, there can be no assurance that Halliburton’s insurance policies will cover all potential claims and expenses relating to the Macondo Well incident. Insurance coverage can be the subject of uncertainties and, particularly in the event of large claims, potential disputes with insurance carriers. Finally, although Halliburton considers it remote, if Halliburton were to be subject to governmental fines or penalties, it is possible Halliburton might not be indemnified or insured.

As of June 30, 2010, Halliburton had not accrued any amounts related to this matter because Halliburton does not believe that a loss is probable.

Halliburton’s Business and Expected Plans

Halliburton is assessing its plans in light of the Macondo Well incident and the prospective regulatory response, including any new temporary or permanent BOE rules. Halliburton is also engaged in discussions with its customers in the Gulf of Mexico and is relocating equipment and personnel to other markets as appropriate. In this connection, Halliburton expects that Gulf of Mexico deepwater activity may be in hiatus for at least six months and possibly longer. However, there is potential for continuing operations in the Gulf of Mexico under the current BOE rules both as to shallow water operations and certain well activities such as water injection and workover operations, but some of these operations have been delayed as well due to the more stringent permitting process.

Halliburton’s business in the Gulf of Mexico represented approximately 12% of its North America revenue in 2008, approximately 16% in 2009 and approximately 12% in the first half of 2010, and approximately 5% of its consolidated revenue in 2008, approximately 6% in 2009 and approximately 6% in the first half of 2010. Currently, approximately 65% of Halliburton’s Gulf of Mexico business is related to deepwater activities. Over time, Halliburton’s margins in the Gulf of Mexico generally have been less volatile than its United States onshore margins. Generally, Halliburton’s average margins in the Gulf of Mexico have been similar to the average of its United States onshore margins over the last three years.

Halliburton is adjusting the allocation of its Gulf of Mexico existing assets and/or anticipated capital expenditures to some degree during the remainder of 2010. At the time of the Macondo Well incident, Halliburton employed approximately 2,200 people in the Gulf of Mexico, and Halliburton has begun

redeploying approximately 20% of its employees. As a result of the Macondo Well incident and the deepwater drilling suspension in the Gulf of Mexico, despite Halliburton’s mitigation efforts, Halliburton estimates that the suspension will negatively impact its earnings by $0.05 to $0.08 per share for each of the third and fourth quarters of 2010 (approximately $0.10 to $0.16 per share for the full year 2010). Longer term, Halliburton does not know the extent of the impact on revenue or earnings, as they are dependent, among other things, on Halliburton’s customers’ actions and the potential movement of deepwater rigs to other markets.

In this respect, Halliburton referenced earlier in 2010 the following contract wins that are at least partially affected as a result of the hiatus in Gulf of Mexico deepwater activity:


	•	a five-year, $1.5 billion contract to provide a broad base of products and services to an international oil company for its work associated with North America; and


	•	several wins totaling $1 billion, including $700 million to provide deepwater drilling fluid services in the Gulf of Mexico, Brazil, Indonesia, Angola, and other countries and $300 million for shelf- and land-related work.

Risk Factors” in Halliburton’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2010.

(1)		The increase in total assets during 2009 was primarily due to the increase in goodwill and intangibles resulting from the acquisition of John Wright Company, or JWC, during 2009 and the increase in deferred debt cost related to the new credit agreement with Wells Fargo Bank, National Association. The increase in total assets during 2008 was primarily due to the increase in receivables which resulted from a substantial increase in revenue in 2008 compared to 2007. It was also a result of an increase in property, plant and equipment due to higher capital expenditures to support Boots & Coots’ higher volume of revenue in 2008. The increase in total assets from 2005 to 2006 is a result of Boots & Coots’ acquisition of the hydraulic well control business of Oil States International, Inc., or HWC, in March 2006.


(2)		The increase in long term debt from 2008 to 2009 is a result of the new credit agreement with Wells Fargo entered into during 2009 used primarily for funding the JWC acquisition. The increase in long term debt from 2007 to 2008 primarily resulted from borrowings to fund working capital and capital expenditure requirements. The increase in long term debt from 2005 to 2006 is a result of borrowings from debt issued and a prior credit agreement with Wells Fargo entered into in conjunction with funding for the acquisition of the HWC, in March 2006.

(3)		The increases in stockholders’ equity from 2008 to 2009 and from 2007 to 2008 are primarily due to net income. The increase from 2006 to 2007 is due to Boots & Coots’ April 2007 underwritten public offering of 14.95 million shares of Boots & Coots common stock which resulted in net proceeds to Boots & Coots of $28.8 million. The increase in stockholders’ equity from 2005 to 2006 is a result of the 26.5 million shares issued for the purchase of HWC valued at $26.5 million.

Unaudited Comparative Per Share Data

The following table sets forth (1) the historical income from continuing operations and net book value per share of Halliburton common stock in comparison to the pro forma income from continuing operations and net book value per share after giving effect to the stock and cash acquisition of Boots & Coots using the acquisition method of accounting and (2) the historical income from continuing operations and net book value per share of Boots & Coots common stock in comparison to the equivalent pro forma income from continuing operations and net book value per share attributable to an assumed 0.0426 shares of Halliburton common stock issued for each share of Boots & Coots common stock. This exchange ratio assumes that the Halliburton five-day average price, calculated as if the transaction occurred on July 27, 2010, was $29.78, and no modification of the allocation of the merger consideration.

The pro forma adjustments for the net book value per share data are based on the assumption that the transaction occurred on June 30, 2010 and December 31, 2009. The pro forma adjustments for the income from continuing operations per share data are based on the assumption that the transaction occurred on January 1, 2009.

The unaudited pro forma data is for informational purposes only. Halliburton and Boots & Coots may have performed differently had Boots & Coots always been a subsidiary of Halliburton. You should not rely on the pro forma data as being indicative of the historical results that would have been achieved had Boots & Coots always been a subsidiary of Halliburton or the future results that Halliburton will experience after the merger. The information presented in this table should be read in conjunction with the consolidated historical financial statements of Halliburton and Boots & Coots and the notes thereto incorporated by reference in this proxy statement/prospectus.

(1)		Boots & Coots did not pay dividends on its common stock during the periods shown.

The following table sets forth the closing sale prices of Halliburton common stock and Boots & Coots common stock as reported on the NYSE and NYSE Amex, respectively, on (i) April 9, 2010, the last full trading day before the public announcement of the proposed merger, and (ii) , 2010, the last practicable trading day prior to mailing this proxy statement/prospectus.

The table also includes the equivalent value of the merger consideration per share of Boots & Coots common stock on April 9, 2010 and , 2010. The cash equivalent prices per share for each date were calculated by multiplying the closing price of Halliburton’s common stock on those dates by 0.0402 and , respectively, which is the total Halliburton common stock consideration that would be issued pursuant to the merger agreement per share of Boots & Coots common stock if the Halliburton five-day average price is equal to those closing prices shown below. To this, we added $1.73 per share, which is the total cash consideration currently expected to be paid pursuant to the merger agreement per share of Boots & Coots common stock. In each case, these amounts were calculated assuming that each Boots & Coots stockholder elected to receive, and would receive, a mix of $1.73 in cash and $1.27 in Halliburton common stock for each Boots & Coots share.

RISK FACTORS

In addition to the other information contained or incorporated by reference into this proxy statement/prospectus, including the matters addressed in “Cautionary Statements Concerning Forward-Looking Statements” on page 32 of this proxy statement/prospectus, you should carefully consider the following risk factors in determining whether to vote for the adoption of the merger agreement. You should also read and consider the risk factors associated with each of the businesses of Halliburton and Boots & Coots because these risk factors may affect the operations and financial results of Halliburton after the merger. Those risk factors may be found in Halliburton’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2010 and in Boots & Coot’s Annual Report on Form 10-K for the year ended December 31, 2009, each of which is on file with the SEC and is incorporated by reference into this proxy statement/prospectus.

The market price of Halliburton common stock after the merger may be affected by factors different from those affecting shares of Boots & Coots stock currently.

Upon completion of the merger, some or all holders of Boots & Coots common stock will become holders of Halliburton common stock. The businesses of Halliburton differ from those of Boots & Coots in important respects and, accordingly, the results of operations of Halliburton after the merger, as well as the market price of its common stock, may be affected by factors different from those currently affecting the independent results of operations of Boots & Coots. For further information on the businesses of Halliburton and Boots & Coots and certain factors to consider in connection with those businesses, see the documents incorporated by reference into this proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 103 of this proxy statement/prospectus.

After completion of the merger, Halliburton may fail to realize the anticipated benefits of the merger, which could adversely affect the value of Halliburton’s common stock.

The success of the merger will depend, in part, on Halliburton’s ability to integrate effectively the businesses of Halliburton and Boots & Coots and realize the anticipated benefits from the acquisition of Boots & Coots. As of the date of this proxy statement/prospectus, Halliburton believes that these benefits, which include the expansion of Halliburton’s completion and production enhancement portfolio, an increase in Halliburton’s ability to improve full life cycle returns for its customers and the creation of a new product service line with a strong global presence and attractive growth prospects, are achievable. However, it is possible that Halliburton will not be able to achieve these benefits fully, or at all, or will not be able to achieve them within the anticipated timeframe. Halliburton and Boots & Coots have operated and, until the completion of the merger, will continue to operate, independently, and there can be no assurance that their businesses can be integrated successfully. If Halliburton’s expectations as to the benefits of the merger turn out to be incorrect, or Halliburton is not able to successfully integrate the businesses of Halliburton and Boots & Coots for any other reason, the value of Halliburton’s common stock (including the stock issued as a portion of the merger consideration) may be adversely affected.

It is possible that the integration process could result in the loss of key Boots & Coots employees, as well as the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies. Specific issues that must be addressed upon completion of the merger in order to realize the anticipated benefits of the merger include, among other things:


	•	integrating the companies’ management teams, strategies, cultures and operations;

	•	retaining existing Boots & Coots customers and partners;

	•	harmonizing the companies’ operating practices, employee development and compensation programs, internal controls and other policies, procedures and processes;

	•	integrating the companies’ corporate, administrative and information technology infrastructure; and

	•	managing any tax costs or inefficiencies associated with integration.

In addition, at times, the attention of certain members of Halliburton’s management and Boots & Coots’ management, and the resources of the two companies, may be focused on the completion of the merger and the integration of the businesses of the two companies and diverted from day-to-day business operations.

Boots & Coots may have difficulty attracting, motivating and retaining officers and other key employees in light of the merger, and the anticipated benefits of the merger could be reduced.

Uncertainty about the effect of the merger on Boots & Coots’ officers and employees may have an adverse effect on Boots & Coots and the anticipated benefits of the merger. This uncertainty may impair Boots & Coots’ ability to attract, retain and motivate key personnel until the merger is completed. Employee retention may be particularly challenging during the pendency of the merger, as employees may experience uncertainty about their future roles with Halliburton.

The success of the merger will depend in part on the retention of personnel critical to the business and operations of Boots & Coots. If Boots & Coots and Halliburton are unable to retain personnel, including certain of Boots & Coots’ key employees who will be critical to the successful integration and future operations of the business of Boots & Coots, Halliburton could face disruptions in its operations, loss of existing customers and loss of key information, expertise or know-how. If officers and other key employees of Boots & Coots depart because of issues relating to the uncertainty and difficulty of integration or a desire not to become employees of Halliburton, Halliburton’s ability to realize the anticipated benefits of the merger could be reduced.

Boots & Coots’ directors and executive officers have interests in the merger that may be different from, and in addition to, the interests of other Boots & Coots stockholders.

When considering the recommendation of Boots & Coots’ board of directors that Boots & Coots stockholders vote in favor of the adoption of the merger agreement, Boots & Coots stockholders should be aware that directors and executive officers of Boots & Coots have interests in the merger that may be different from, or in addition to, the interests of a stockholder of Boots & Coots. In particular, directors and executive officers of Boots & Coots have rights to acceleration of stock options, SARs, restricted stock and other benefits triggered immediately prior to or upon completion of the merger and have rights to continued indemnification and insurance coverage after the completion of the merger. In addition, executive officers of Boots & Coots have employment and severance benefit arrangements triggered immediately prior to or upon completion of the merger. Boots & Coots’ board of directors was aware of these interests and considered them, among other things, in evaluating and negotiating the merger agreement and the merger and in making its recommendation that Boots & Coots stockholders vote in favor of the adoption of the merger agreement. See “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests.”

Boots & Coots stockholders electing to receive only cash or only Halliburton common stock may receive a form or combination of consideration different from the form they elect.

While each Boots & Coots stockholder may elect to receive consideration consisting of cash, shares of Halliburton common stock or a combination of both in exchange for their shares of Boots & Coots common stock, the aggregate cash consideration to be received by Boots & Coots stockholders pursuant to the merger will, subject to certain exceptions, be fixed at an amount equal to the product of $1.73 and the number of issued and outstanding shares of Boots & Coots common stock immediately prior to closing of the merger (including restricted stock and excluding certain shares), which cash amount is expected to be approximately $143.2 million based on the number of shares of Boots & Coots common stock and restricted stock outstanding as of July 27, 2010. Accordingly, if Boots & Coots stockholders elect, in the aggregate, to receive cash in an amount greater than the aggregate cash consideration payable under the merger agreement, or less than the aggregate cash consideration payable under the merger agreement, then those holders electing to receive either all cash or all stock consideration, as the case may be, will be pro rated down and will receive the undersubscribed form of merger consideration as a portion of the overall consideration they receive for their shares. As a result, depending on the elections made by other Boots & Coots stockholders, if a Boots & Coots stockholder elects to receive all cash pursuant to the merger, that stockholder could receive a portion of

the merger consideration in Halliburton common stock instead of cash or, if a Boots & Coots stockholder elects to receive all Halliburton common stock pursuant to the merger, that stockholder could receive a portion of the merger consideration in cash instead of Halliburton common stock.

As a result of the consideration election of the merger agreement, and because the market price of Halliburton common stock will fluctuate, Boots & Coots stockholders cannot be sure of the aggregate value of the merger consideration they will receive.

As described above, the stock portion of the merger consideration will be calculated based on the Halliburton five-day average price, which will be determined as of the second full trading day immediately prior to the effective time of the merger (referred to in this proxy statement/prospectus as the calculation date). Once the Halliburton five-day average price is determined, it will, subject to certain exceptions relating to appraisal rights or the tax-free status of the merger, be fixed and will not be adjusted due to any increase or decrease in the price per share of Halliburton common stock after the calculation date. Accordingly, the dollar value of the consideration received by Boots & Coots stockholders receiving consideration that includes Halliburton common stock will depend upon the market value of Halliburton common stock at the effective time of the merger, and such dollar value may be different from, and lower than, the dollar value of the merger consideration on the calculation date. Moreover, the Halliburton five-day average price will likely vary from the market price of Halliburton common stock on the date the merger agreement was announced, on the date that this proxy statement/prospectus is mailed to Boots & Coots stockholders, on the date a Boots & Coots stockholder makes an election with respect to the merger consideration, on the date of the special meeting of Boots & Coots stockholders and after the closing of the merger.

If you tender shares of Boots & Coots common stock to make an election, you will not be able to sell those shares unless you revoke your election prior to the election deadline.

If you are a Boots & Coots stockholder and want to make a cash or stock election, you must deliver your stock certificates (or follow the procedures for guaranteed delivery) and a properly completed and signed election form to the exchange agent. The deadline for doing this is 5:00 p.m., New York time, on , 2010. You will not be able to sell any shares of Boots & Coots common stock that you have delivered unless you revoke your election before the deadline by providing written notice to the exchange agent. If you do not revoke your election, you will not be able to liquidate your investment in Boots & Coots common stock for any reason until you receive cash and/or Halliburton common stock pursuant to the merger. In the time between delivery of your shares and the closing of the merger, the market price of Boots & Coots or Halliburton common stock may increase or decrease and you might otherwise want to sell your shares of Boots & Coots to gain access to cash, make other investments or reduce the potential for a decrease in the value of your investment.

The date that Boots & Coots stockholders will receive the merger consideration is uncertain.

The date that Boots & Coots stockholders will receive the merger consideration depends on the completion date of the merger, which is uncertain. While we expect to complete the merger during the third quarter of 2010, the completion date of the merger might be later than expected because of delays in obtaining

stockholder and governmental approvals or because of unforeseen events. In no event will the merger be completed later than October 1, 2010 (December 1, 2010 if all conditions to the merger other than the termination or expiration of the waiting period under the HSR Act or any statute requiring premerger notification have been fulfilled or are capable of being fulfilled) unless Halliburton and Boots & Coots otherwise agree.

Business uncertainties and contractual restrictions while the merger is pending may have an adverse effect on Boots & Coots.

Uncertainty about the effect of the merger on suppliers, partners and customers may have an adverse effect on Boots & Coots. These uncertainties may cause suppliers, customers and others that deal with Boots & Coots to defer purchases or other decisions concerning Boots & Coots or seek to change existing business relationships with Boots & Coots. In addition, the merger agreement restricts Boots & Coots from making certain acquisitions and taking other specified actions without Halliburton’s approval. These restrictions could prevent Boots & Coots from pursuing certain business opportunities that may arise prior to the completion of the merger. The adverse effect of such disruptions could be exacerbated by a delay in the completion of the merger or termination of the merger agreement.

Failure to complete the merger could negatively impact the stock price and the future business and financial results of Boots & Coots.

If the merger is not completed, the ongoing businesses of Boots & Coots may be adversely affected and, without realizing any of the benefits of having completed the merger, Boots & Coots would be subject to a number of risks, including the following:


	•	Boots & Coots may experience negative reactions from its customers and employees;

	•	the current market price of Boots & Coots common stock may reflect a market assumption that the merger will occur and a failure to complete the merger could result in a negative perception by the stock market and a resulting decline in the market price of Boots & Coots common stock;

	•	certain costs relating to the merger, including certain investment banking, financing, legal and accounting fees and expenses, must be paid even if the merger is not completed, and Boots & Coots may be required to pay a fee of $10.0 million or expense reimbursements up to $1.5 million to Halliburton if the merger agreement is terminated under specified circumstances; and

	•	there may be substantial disruption to Boots & Coots’ business and distraction of Boots & Coots’ management and employees from day-to-day operations because matters related to the merger (including integration planning) may require substantial commitments of time and resources, which could otherwise have been devoted to other opportunities that could have been beneficial to Boots & Coots.

There can be no assurance that the risks described above will not materialize, and if any of them do, they may materially adversely affect Boots & Coots’ business, financial results and stock price.

The merger agreement restricts Boots & Coots’ ability to pursue alternatives to the merger and requires Boots & Coots to pay a termination fee of $10.0 million if it does.

The merger agreement contains “no shop” provisions that, subject to limited fiduciary exceptions, restrict Boots & Coots’ ability to initiate, solicit or encourage or take any action to facilitate, discuss, negotiate or accept a competing third party proposal to acquire 15% or more of Boots & Coots’ assets, revenues, net income or equity securities. Further, only in limited circumstances may Boots & Coots’ board of directors withdraw or change its recommendation to holders of Boots & Coots common stock that they vote in favor of the adoption of the merger agreement. Although Boots & Coots’ board of directors is permitted to take these actions if it determines in good faith that these actions are likely to be required to comply with its fiduciary duties, doing so in specified situations could entitle Halliburton to be paid a termination fee of $10.0 million.

Halliburton required that Boots & Coots agree to these provisions as a condition to Halliburton’s willingness to enter into the merger agreement. However, these provisions could discourage a potential acquiror that might have an interest in acquiring all or a significant part of Boots & Coots from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the consideration Halliburton proposes to pay in the merger or might result in a potential competing acquiror proposing to pay a lower per share price to acquire Boots & Coots than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable to Halliburton in certain circumstances.

Boots & Coots stockholders will own less than 1.0% of Halliburton common stock immediately after the merger and will exercise significantly less influence over management.

Immediately after the completion of the merger, it is expected that former Boots & Coots stockholders, who collectively own 100% of Boots & Coots common stock, will own less than 1.0% of Halliburton common stock. Consequently, immediately after the completion of the merger, Boots & Coots stockholders will have significantly less influence over the management and policies of Halliburton than they currently have over the management and policies of Boots & Coots.

The rights of Boots & Coots stockholders will be governed by Halliburton’s restated certificate of incorporation and by-laws.

All Boots & Coots stockholders who receive shares of Halliburton common stock in the merger will become Halliburton stockholders and their rights as stockholders will be governed by Halliburton’s restated certificate of incorporation and by-laws. There are material differences between the current rights of Boots & Coots stockholders, which are governed by Boots & Coots’ amended and restated certificate of incorporation and by-laws, and the rights of holders of Halliburton common stock. See “Comparison of Stockholder Rights” beginning on page 96.

Halliburton and Boots & Coots may also provide oral or written forward-looking information in other materials they release to the public. Forward-looking information involves risk and uncertainties and reflects Halliburton’s and Boots & Coots’, as applicable, best judgment based on current information. The results of operations and business strategies of Halliburton and Boots & Coots, and the plans and objectives for the future operation of Halliburton following the merger and the integration of the businesses of Halliburton and Boots & Coots, can be affected by inaccurate assumptions that are made or by known or unknown risks and uncertainties. In addition, other factors may affect the accuracy of forward-looking information. As a result, no forward-looking information can be guaranteed.

We also suggest that you listen to Halliburton’s and Boots & Coots’ earnings release conference calls with financial analysts.

The following important factors, in addition to those discussed under “Risk Factors” and elsewhere in this proxy statement/prospectus and the documents incorporated by reference in this proxy statement/prospectus, could cause actual results to differ materially from those expressed in or implied by forward-looking statements:


	•	the expenses of the merger being greater than anticipated, including as a result of unexpected factors or events;

	•	the exposure to litigation, including the possibility that litigation relating to the merger could delay or impede the completion of the merger;

	•	the integration of Boots & Coots’ business and operations with those of Halliburton taking longer than anticipated, being costlier than anticipated and having unanticipated adverse results relating to Halliburton’s or Boots & Coots’ existing businesses;

	•	attrition in key customers, partners and other relationships relating to the merger;

	•	changes in economic, business, competitive and/or regulatory factors;

	•	the failure to receive the required stockholder and regulatory approvals for the merger or to satisfy any of the closing conditions to the merger; and

	•	the failure to retain officers and key employees.

THE STOCKHOLDER MEETING

Boots & Coots’ board of directors is using this document to solicit proxies from Boots & Coots stockholders for use at Boots & Coots’ special meeting of stockholders. In addition, this document constitutes a prospectus covering the issuance of Halliburton common stock pursuant to the merger agreement.

Date, Time and Place

The special meeting of Boots & Coots’ stockholders will be held at on , 2010, at , local time.

Purpose

The purpose of the Boots & Coots special meeting is as follows:


	1.	to consider and vote upon a proposal to adopt the merger agreement; and

	2.	to consider and vote upon any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies in favor of the foregoing proposal.

Board Recommendation

Boots & Coots’ board of directors has adopted a resolution approving the merger agreement, declared the merger agreement advisable and determined that the merger agreement and the transactions contemplated by it are fair to and in the best interests of Boots & Coots and its stockholders, and recommends that Boots & Coots stockholders vote at the special meeting to adopt the merger agreement and to approve any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies. As described under “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests” beginning on page 60, Boots & Coots directors and executive officers have agreements and arrangements that provide them with interests in the merger that may be different from, or are in addition to, those of Boots & Coots stockholders.

Record Date; Outstanding Shares; Shares Entitled to Vote

The record date for the Boots & Coots special meeting is , 2010. Only holders of record of Boots & Coots common stock at the close of business on the record date are entitled to notice of, and to vote at, the Boots & Coots special meeting. At the close of business on the record date, there were shares of Boots & Coots common stock issued and outstanding held by approximately holders of record. Each share of Boots & Coots common stock entitles the holder of that share to one vote on each matter submitted for stockholder approval.

Quorum

A quorum of stockholders is required for Boots & Coots stockholders to take action on the proposal to adopt the merger agreement at the special meeting, but not to approve any adjournment of the meeting. The presence at the special meeting, in person or by proxy, of the holders of a majority of the outstanding shares of Boots & Coots common stock entitled to vote at the close of business on the record date will constitute a quorum. Proxies received but marked as abstentions, if any, will be included in the calculation of the number of shares considered to be present at the meeting for quorum purposes. With respect to broker non-votes, the adoption of the merger agreement is not considered a routine matter. Therefore, your broker will not be permitted to vote on the adoption of the merger agreement without instruction from you as the beneficial owner of the shares of Boots & Coots common stock. Broker non-votes will, however, be counted for purposes of determining whether a quorum is present at the special meeting.

Required Vote

To adopt the merger agreement, holders of a majority of the shares of Boots & Coots common stock outstanding and entitled to vote on the proposal must vote in favor of adoption of the merger agreement. Because approval is based on the affirmative vote of a majority of the outstanding shares of Boots & Coots common stock, a Boots & Coots stockholder’s failure to submit a proxy or to vote in person at the special meeting, an abstention from voting, or the failure of a Boots & Coots stockholder who holds his or her shares in “street name” through a broker or other nominee to give voting instructions to such broker or other nominee, will have the same effect as a vote AGAINST adoption of the merger agreement.

Any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies, requires the affirmative vote of the holders of Boots & Coots common stock representing a majority of the votes present in person or by proxy at the special meeting and entitled to vote, whether or not a quorum exists, without further notice other than by announcement made at the special meeting, so long as the adjournment is for 30 days or less and no new record date is set. Abstentions will have the same effect as a vote AGAINST the proposal to adjourn the special meeting, while broker non-votes and shares not in attendance at the special meeting will have no effect on the outcome of any vote to adjourn the special meeting.

Tabulation of the Votes

Boots & Coots has appointed American Stock Transfer & Trust Company, LLC, or AST, to serve as the Inspector of Election for the Boots & Coots special meeting. AST will independently tabulate affirmative and negative votes and abstentions.

Stock Ownership of and Voting by Boots & Coots’ Directors and Executive Officers

At the close of business on the record date for the Boots & Coots special meeting, Boots & Coots’ directors and executive officers and their affiliates collectively beneficially owned approximately shares of Boots & Coots common stock, which represents approximately % of the Boots & Coots common stock entitled to vote at the Boots & Coots special meeting. It is expected that Boots & Coots directors and executive officers will vote their shares FOR approval of the merger agreement and the merger.

Voting of Shares by Holders of Record

If you are entitled to vote at the special meeting and hold your shares in your own name, you can submit a proxy or vote in person by completing a ballot at the special meeting. However, Boots & Coots encourages you to submit a proxy before the special meeting even if you plan to attend the special meeting in order to ensure that your shares are voted. A proxy is a legal designation of another person to vote your shares of Boots & Coots common stock on your behalf. If you hold shares in your own name, you may submit a proxy for your shares by:


	•	Telephone. You can vote by telephone by calling the toll-free number (800) 776-9437 in the United States, Canada or Puerto Rico on a touch-tone telephone. You will then be prompted to enter the control number printed on your proxy card and to follow the subsequent instructions. Telephone voting is available 24 hours a day until 11:59 p.m., New York time, on , 2010. If you vote by telephone, you do not need to return your proxy card or voting instruction card.


	•	Internet. You can vote over the Internet by accessing the website at www.voteproxy.com and following the instructions on the secure website. Internet voting is available 24 hours a day until 11:59 p.m., New York time, on , 2010. If you vote over the Internet, you do not need to return your proxy card or voting instruction card.


	•	Mail. You can vote by mail by completing, signing, dating and mailing your proxy card or voting instruction card in the postage-paid envelope included with this proxy statement/prospectus.

When a stockholder submits a proxy by telephone or through the Internet, his or her proxy is recorded immediately. Boots & Coots encourages its stockholders to submit their proxies using these methods whenever

possible. If you submit a proxy by telephone or the Internet website, please do not return your proxy card by mail.

All shares represented by each properly executed and valid proxy received before the special meeting will be voted in accordance with the instructions given on the proxy. If a Boots & Coots stockholder executes a proxy card without giving instructions, the shares of Boots & Coots common stock represented by that proxy card will be voted FOR approval of the proposal to adopt the merger agreement and the proposal to approve any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies in favor of the foregoing proposal.

Your vote is important. Accordingly, please submit your proxy by telephone, through the Internet or by mail, whether or not you plan to attend the meeting in person. Proxies must be received by 11:59 p.m., New York time, on , 2010.

Voting of Shares Held in Street Name

If your shares are held in an account at a broker or through another nominee, please refer to your proxy card or voting instruction form or the information forwarded by your bank, broker, custodian or other record holder to see which voting methods are available to you. You must instruct the broker or other nominee on how to vote your shares by following the instructions that the broker or other nominee provides to you with these proxy materials. Most brokers offer the ability for stockholders to submit voting instructions by mail by completing a voting instruction card, by telephone and via the Internet.

If you do not provide voting instructions to your broker, your shares will not be voted on any proposal on which your broker does not have discretionary authority to vote. This is referred to in this proxy statement/prospectus and in general as a “broker non-vote.” In these cases, the broker or other nominee can register your shares as being present at the special meeting for purposes of determining a quorum, but will not be able to vote your shares on those matters for which specific authorization is required. Under the current rules of the NYSE, brokers do not have discretionary authority to vote on the proposal to adopt the merger agreement or the proposal to approve any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies. Therefore, a broker non-vote will have the same effect as a vote AGAINST adoption of the merger agreement but will have no effect on the vote to approve any adjournment of the special meeting, if necessary or appropriate to solicit additional proxies.

If you hold shares through a broker or other nominee and wish to vote your shares in person at the special meeting, you must obtain a proxy from your broker or other nominee and present it to the inspector of election with your ballot when you vote at the special meeting.

Revocability of Proxies; Changing Your Vote

You may revoke your proxy and/or change your vote at any time before your proxy is voted at the special meeting. If you are a stockholder of record, regardless of the method you used to cast your vote, you can do this by:


	•	sending a written notice stating that you revoke your proxy to Boots & Coots at 7908 N. Sam Houston Parkway W., 5th Floor, Houston, Texas 77064, Attn: Corporate Secretary that bears a date later than the date of the proxy and is received prior to the special meeting and states that you revoke your proxy;

	•	submitting a valid, later-dated proxy by mail, telephone or Internet that is received prior to the applicable deadline; or

	•	attending the special meeting and voting by ballot in person (your attendance at the special meeting will not, by itself, revoke any proxy that you have previously given).

If you hold your shares in “street name” and wish to change or revoke your vote, please refer to the information on the voting instruction form included with these materials and forwarded to you by your bank, broker, custodian or other record holder to see your voting options.

Solicitation of Proxies

This proxy statement/prospectus is furnished in connection with the solicitation of proxies by the Boots & Coots board of directors to be voted at the Boots & Coots special meeting. Boots & Coots has engaged The Altman Group to assist in the solicitation of proxies for the special meeting. Pursuant to the merger agreement, Halliburton will pay the $6,000 fee of the proxy solicitor. Halliburton will reimburse The Altman Group for reasonable out-of-pocket expenses and disbursements incurred in connection with the proxy solicitation. Boots & Coots has agreed to indemnify The Altman Group against certain losses, costs and expenses. In addition, The Altman Group may reimburse brokerage firms and other persons representing beneficial owners of shares of Boots & Coots common stock for their reasonable expenses in forwarding solicitation materials to such beneficial owners. Boots & Coots will bear all other costs and expenses in connection with the solicitation of proxies. Proxies may also be solicited by certain of Boots & Coots directors, officers and employees by telephone, electronic mail, letter, facsimile or in person, but no additional compensation will be paid to them.

Stockholders should not send Boots & Coots stock certificates with their proxy cards. Rather, prior to the election deadline, stockholders should send any Boots & Coots common stock certificates (or a properly completed notice of guaranteed delivery), together with a completed, signed election form, to the exchange agent identified in the election form. The election form and instructions will be delivered to Boots & Coots stockholders together with this proxy statement/prospectus or in a separate mailing.

No Other Business

Under Boots & Coots’ amended and restated certificate of incorporation and by-laws, the business to be conducted at the special meeting will be limited to the purposes stated in the notice to Boots & Coots stockholders provided with this proxy statement/prospectus.

THE MERGER

Background of the Merger

Halliburton’s senior management regularly evaluates and periodically reviews with Halliburton’s board of directors strategies to enhance stockholder value, including opportunities to enhance the services it provides to its customers and its overall position in the energy services industry. One of the areas for potential growth that Halliburton has considered is the expansion of its completion and production enhancement portfolio. Halliburton believes that an increased presence and expertise in pressure control and well intervention services will enable it to improve full life cycle returns for its customers.

Similarly, as part of the continuous evaluation of its business, Boots & Coots’ board of directors and management regularly evaluate Boots & Coots’ business strategy and prospects for growth and consider opportunities to create value for its stockholders. Boots & Coots’ strategic reviews have frequently resulted in considering and completing acquisitions of and combinations with other companies, as well as joint ventures with other companies.

As part of each company’s ongoing evaluation of its businesses and opportunities, in November and December of 2008, representatives of Halliburton and Boots & Coots began discussing a potential joint venture involving their respective hydraulic workover operations, or HWO. On December 10, 2008, David King, President, Completion and Production Division of Halliburton, and Jerry Winchester, Chief Executive Officer and Director of Boots & Coots, met to discuss the benefits of a possible joint venture. Messrs. King and Winchester both expressed an interest in the possible advantages of such a joint venture, including that the respective HWO businesses of the two companies would be complementary of each other and that there did not exist much overlap in the geographic presence of their HWO businesses. Messrs. King and Winchester decided that Halliburton and Boots & Coots should consult with their respective management teams to determine whether further discussions and exploring the possibility of a joint venture would be fruitful.

In December 2008 and January 2009, both sides continued to consider a possible joint venture and agreed that each party should begin conducting due diligence. On January 7, 2009, Halliburton Energy Services, Inc., a wholly owned subsidiary of Halliburton and which we refer to herein as Halliburton Energy, and Boots & Coots executed a confidentiality agreement. Under the terms of the confidentiality agreement, each party agreed to treat confidentially certain proprietary information shared by the other party to enable them to analyze a possible transaction involving Boots & Coots and the HWO business of Halliburton. In addition, the confidentiality agreement contained, among other things, standstill restrictions that, in accordance with and subject to the terms of the confidentiality agreement, prohibited Halliburton from making an unsolicited offer to acquire securities of Boots & Coots for a period of one year.

From January 2009 through April 8, 2009, Halliburton and Boots & Coots conducted high-level business due diligence.

On April 8, 2009, Boots & Coots sent Halliburton a non-binding term sheet that outlined financial and business arrangements of a transaction pursuant to which Boots & Coots would acquire Halliburton’s HWO business. The parties had subsequent discussions regarding a joint venture including ownership and governance. However, Halliburton and Boots & Coots could not agree to terms, and discussions terminated in late April 2009.

Prior to the termination of the HWO joint venture discussions, Boots & Coots had expressed interest in purchasing Halliburton’s abrasive jet cutting systems and discussions regarding that transaction continued. On September 11, 2009, Boots & Coots and Halliburton Energy entered into an agreement providing for Boots & Coots to purchase Halliburton’s abrasive jet cutting systems for $420,000. The transaction closed the same day.

In early August 2009, Boots & Coots received an unsolicited letter from a public company, or Company A, expressing general interest in a potential stock-for-stock acquisition of Boots & Coots without specifying financial terms. A telephonic meeting of the board of directors was held on August 12, 2009, with a representative of Thompson & Knight LLP, Boots & Coots’ outside counsel, or Thompson & Knight, in

attendance. At the board’s request, the representative of Thompson & Knight reviewed with the board its fiduciary obligations under Delaware law. The board discussed, among other things, the current acquisition environment, including premiums being paid in publicly announced transactions among oil field service companies, the trading price of Boots & Coots common stock, the business prospects of Boots & Coots and publicly available information regarding various aspects of the business, financial condition and prospects of Company A. The consensus of the Boots & Coots board of directors was that Boots & Coots common stock was undervalued and that current market conditions were not conducive to securing a substantial enough premium to the trading price of Boots & Coots common stock to warrant active consideration of a sale of Boots & Coots. With respect to Company A, the consensus of the Boots & Coots board of directors was that further discussions would be unlikely to yield a suitable transaction structure and a substantial enough premium to the market price of Boots & Coots common stock that it would reflect fair value for Boots & Coots common stock. The board directed Mr. Winchester to inform Company A that Boots & Coots was not interested in pursuing such a transaction at that time.

On September 16, 2009, at Mr. Winchester’s request, Mr. Winchester and Mr. King resumed discussions regarding Boots & Coots’ proposed acquisition of the HWO business of Halliburton. During that meeting, Mr. King inquired about whether Boots & Coots would be interested in exploring a transaction in which Halliburton acquired Boots & Coots. Mr. King stated that Halliburton would like for Boots & Coots’ current management team to remain intact and continue to manage Boots & Coots’ business, together with Halliburton’s coiled tubing and HWO business, as a subsidiary of Halliburton. Mr. Winchester responded that, as a general matter, Boots & Coots was not interested in pursuing a sale but that it was interested in continuing general discussions of a joint venture or other combination if Halliburton was similarly committed to moving forward.

On September 21, 2009, Messrs. Winchester and King again met and discussed Halliburton’s interest in acquiring Boots & Coots. At this meeting, Mr. Winchester informed Mr. King that it made sense to continue that line of discussions only if Halliburton was willing to consider an offer that represented a substantial premium to the trading price of Boots & Coots common stock. Mr. King arranged a meeting between Mr. Winchester and David Lesar, Chairman of the Board, President and Chief Executive Officer of Halliburton, for September 28, 2009, to discuss the matter further.

On September 28, 2009, Mr. Winchester met with Messrs. Lesar and King. Mr. Lesar affirmed Halliburton’s interest in pursuing a potential acquisition of Boots & Coots and indicated that he thought a transaction at a substantial premium to the trading price of Boots & Coots common stock was possible, assuming Boots & Coots’ current management team would remain intact and continue to manage Boots & Coots’ business, in combination with Halliburton’s coiled tubing and HWO business, as a subsidiary of Halliburton. Following this meeting, Mr. Winchester discussed the meeting informally with certain members of the board of directors of Boots & Coots, including the Chairman of the Board, and reported that Halliburton appeared more inclined to pursue an acquisition of Boots & Coots than to consider a joint venture or a sale of its HWO business to Boots & Coots. As a result of these discussions, a meeting of the board of directors of Boots & Coots was scheduled for October 14, 2009.

On October 13, 2009, Mr. Winchester met with Mr. King and informed him that a meeting of the Boots & Coots board of directors had been scheduled for the following day, and that he intended to inform the board generally of Halliburton’s expression of interest in acquiring Boots & Coots at that meeting. Mr. King confirmed that Halliburton remained interested in pursuing an acquisition of Boots & Coots.

On October 14, 2009, a special meeting of the board of directors of Boots & Coots was held at Boots & Coots’ corporate offices. At the meeting, Mr. Winchester informed the Boots & Coots board of directors of Halliburton’s expression of interest in acquiring Boots & Coots. A representative of Thompson & Knight was also present at the meeting and reviewed for the board its fiduciary obligations under Delaware law. The board discussed, among other things, the current acquisition environment, including premiums being paid in publicly announced transactions among oil field service companies, the trading price of Boots & Coots common stock and Boots & Coots’ business prospects. The board also discussed various possible responses to Halliburton, including the prospects of acquiring Halliburton’s HWO business and the potential for receiving an acquisition

offer from Halliburton that fairly reflected the value of Boots & Coots. Management and the board also discussed the strategic rationale behind Halliburton’s interest in acquiring Boots & Coots, including its intention that Boots & Coots’ management and business model be combined with Halliburton’s coiled tubing and HWO business, and also discussed other potentially interested parties and the likelihood of securing a superior transaction by approaching other potential acquirers or initiating an auction process. The board also discussed the business risks associated with pursuing each of these alternatives, including the potential adverse effects that a prolonged multi-party or auction process might have on Boots & Coots’ management, employees and business and the possibility that Halliburton would terminate all discussions if Boots & Coots chose to pursue those alternatives.

After discussion, the consensus of the Boots & Coots board of directors was that Boots & Coots common stock was currently undervalued and that Halliburton’s strategic interest in having the management of Boots & Coots operate the companies’ combined HWO businesses presented an opportunity to secure a premium for stockholders. The board’s assessment was that an offer of $3.00 or more per share would warrant serious consideration; however, the board was not convinced that an offer at such a substantial premium to the market price of Boots & Coots common stock was likely in light of the current transaction environment and current and anticipated business conditions. The board directed Mr. Winchester to inform Halliburton that its desire was to consider a joint venture or acquisition involving Halliburton’s HWO business and that it did not favor a sale of Boots & Coots at that time. The board authorized management to provide updated business information to Halliburton, primarily to facilitate discussions in respect of a joint venture or acquisition by Boots & Coots of Halliburton’s HWO business which the board desired management to continue to pursue, but recognizing that certain information might be utilized by Halliburton to develop a proposal for the acquisition of Boots & Coots.

On October 22, 2009, Mr. Winchester advised Mr. King that Boots & Coots remained interested in a joint venture or acquisition involving Halliburton’s HWO business and that he was authorized to provide updated business information to facilitate discussions in that regard.

On November 3, 2009, representatives of Boots & Coots gave a management presentation to representatives of Halliburton. The presentation focused on Boots & Coots’ business prospects, financial results and strategic plan pertaining to a joint venture.

During the remainder of 2009 and early January 2010, representatives of Halliburton and Boots & Coots engaged in discussions regarding and began conducting business and legal due diligence.

On January 14, 2010, Messrs. King and Winchester met, and Mr. King stated that Halliburton remained interested in acquiring Boots & Coots and that it was prepared to begin working on a formal proposal to acquire all of the issued and outstanding stock of Boots & Coots. Mr. Winchester indicated that any proposal would have to represent a premium in excess of 70% to the current market price of Boots & Coots common stock (which was then $1.74 per share) to be considered seriously.

Throughout January 2010, Halliburton management held internal discussions focusing on the operational fit and expected financial performance of Boots & Coots. Halliburton management considered, among other things, estimated financial results of Boots & Coots for the period as of and for the year ended December 31, 2009 and publicly available financial results and future estimates relating to Boots & Coots. Halliburton also began consulting with Baker Botts L.L.P., Halliburton’s outside counsel, or Baker Botts, about the legal aspects of a possible transaction with Boots & Coots.

On January 15, 2010, a regularly scheduled meeting of the Boots & Coots board of directors was held at Boots & Coots’ corporate offices during which management presented its business, financial and strategic plan for the forthcoming year. The meeting included discussions regarding limitations on Boots & Coots’ opportunities for internally generated organic growth, complementary acquisitions and other strategic international growth opportunities, which limitations were due, in part, to the limited number of suitable acquisition opportunities, Boots & Coots’ limited capital resources and the trading price of its common stock. Discussions also centered around the discounted value at which Boots & Coots common stock traded when compared to its peer group, despite efforts by Mr. Winchester and Cary Baetz, Chief Financial Officer of Boots & Coots, to raise its profile.

On January 19, 2010, an executive of Company A telephoned Mr. Winchester and again expressed interest in acquiring Boots & Coots. During their discussion, Mr. Winchester stated that any proposal would have to represent a premium in excess of 70% to the current market price of Boots & Coots common stock (which was then $1.74 per share) to be considered seriously and that an all stock-for-stock transaction as had been suggested in the August letter was not likely to be considered attractive by the Boots & Coots board of directors. The executive of Company A indicated a willingness to consider such a premium and some flexibility in the form of consideration in a potential transaction.

On January 22, 2010, Mr. King telephoned Mr. Winchester and indicated that Halliburton could consider a potential acquisition of all of the issued and outstanding common stock of Boots & Coots for a combination of Halliburton common stock and cash valued at $3.10 per share of Boots & Coots common stock. Mr. Winchester indicated that he believed that the board of directors of Boots & Coots would consider such a transaction and that he would discuss the proposed terms with the board.

On January 25, 2010, Mr. Winchester met with Mr. Lesar, who affirmed Halliburton’s interest in submitting a formal proposal for the potential acquisition of all of the common stock of Boots & Coots and discussed retaining Boots & Coots’ current management team intact to manage Boots & Coots’ business together with Halliburton’s coiled tubing and HWO business.

On January 26, 2010, a meeting of the Boots & Coots board of directors was convened, with all directors attending in person or by telephone. A representative of Thompson & Knight also attended the meeting. At the meeting, Mr. Winchester reported the substance of his prior conversations with Mr. King and the executive of Company A. The representative of Thompson & Knight then reviewed with the board its fiduciary obligations under Delaware law under the circumstances. The directors then discussed Boots & Coots’ expected financial performance and potential market valuation, as well as the performance of Boots & Coots’ stock over the past three years compared to the market and Boots & Coots’ peer group.

The Boots & Coots board of directors also discussed the potential for receiving higher acquisition proposals and the various factors that the board believed would influence the likelihood of concluding a transaction with either of Halliburton or Company A on the terms they had suggested. With respect to Halliburton, the board considered, among other things, that Halliburton would be able to fund a transaction involving a substantial cash component without having to obtain external financing and that it appeared motivated by a strategic interest in acquiring Boots & Coots and retaining its management. With respect to Company A, the board believed, based upon publicly available financial information, that it would require third party financing to fund a transaction involving a significant cash component, which brought substantial risk and uncertainty to any transaction involving Company A. The board re-visited the potential of simultaneous negotiations with multiple parties with a view to selling the company, and concluded there was a significant risk that Halliburton, and perhaps both parties, would terminate discussions under those circumstances and that such a process posed significant risks to Boots & Coots’ business, including the potential loss of key employees.

The independent members of the Boots & Coots’ board then met in executive session and continued discussions. Subsequently, the full board convened and authorized Mr. Winchester to seek a written proposal from Halliburton upon the terms discussed in his conversations with Messrs. Lesar and King. Mr. Winchester then telephoned Mr. King and requested such a proposal. Mr. Winchester did not immediately respond to Company A but, on March 3, 2010, informed a representative of Company A that management of Boots & Coots was focused on other matters at that time.

On January 27, 2010, Halliburton sent a non-binding letter to Boots & Coots regarding Halliburton’s interest in acquiring all of the issued and outstanding common stock of Boots & Coots. In the letter, Halliburton proposed a transaction in which Halliburton would deliver consideration valued at $3.10 per share of Boots & Coots common stock, comprised of at least 40% in Halliburton common stock and the balance in cash. The letter stated that the proposed consideration was based on an assumption that Boots & Coots had 82.8 million shares of common stock outstanding on a fully diluted basis as of January 27, 2010 and was subject to the completion of due diligence.

In connection with the proposal letter, on January 27, 2010 Halliburton sent Boots & Coots an exclusivity agreement that, among other things, prohibited Boots & Coots from soliciting other proposals, engaging in any negotiations or entering into an agreement relating to a takeover proposal with another party for a period of 60 days.

On January 28, 2010, the Boots & Coots board of directors held a telephonic meeting to discuss the January 27, 2010 letter from Halliburton and the exclusivity agreement. The board, having evaluated a broad range of potential alternatives, including remaining independent, pursuing acquisitions of complementary businesses, joint ventures, and engaging in negotiations to sell the company with multiple parties, determined that pursuing a transaction with Halliburton was in the best interests of the stockholders of Boots & Coots and authorized management to execute the exclusivity agreement. The board also discussed the potential engagement of several different investment banking firms to provide the board with an independent analysis of the consideration to be paid in the proposed transaction and its fairness to the stockholders of Boots & Coots. The board authorized management to contact HFBE regarding the engagement. HFBE had previously provided analyses and a fairness opinion to Boots & Coots in connection with its acquisition of the HWO business of Oil States International, Inc. in 2006, and was therefore known to be very familiar with Boots & Coots and the industry generally.

On January 28, 2010, Mr. Winchester notified Mr. King that the Boots & Coots board of directors decided to explore a potential combination transaction with Halliburton and proceed with due diligence. Mr. Winchester also sent an executed copy of the exclusivity agreement to Mr. King.

On January 29, 2010, representatives of Halliburton and Boots & Coots met to discuss the due diligence process. On February 2, 2010, Halliburton sent a request for certain due diligence documents and materials relating to Boots & Coots. On February 3, 2010, Halliburton engaged Ernst & Young LLP to conduct financial accounting due diligence, including a review of Boots & Coots’ audit workpapers, accounting policies and quality of earnings. Representatives of Halliburton, Baker Botts and Ernst & Young conducted due diligence with respect to Boots & Coots during February, March and the first week of April 2010.

On February 4, 2010, a meeting of the compensation committee of the board of directors of Boots & Coots was held as part of Boots & Coots’ annual compensation process. At the meeting, the committee discussed, among other things, the impact that the proposed transaction with Halliburton would have, if consummated (including the timing of any such consummation), under Boots & Coots’ equity compensation plans, and the employment and severance arrangements (including applicable change of control payments) of management. Further, the committee also discussed the extent to which the annual compensation decisions of the compensation committee could affect Halliburton’s valuation of Boots & Coots and the impact on employees of delaying the customary schedule of incentive awards pending resolution of a potential transaction with Halliburton.

On February 10, 2010, the Halliburton board of directors held a regularly scheduled meeting during which the proposed transaction with Boots & Coots, including a possible timeline, valuation and a summary of Boots & Coots’ business, was discussed. The Halliburton board of directors concurred with management’s recommendation to continue discussions with and due diligence with respect to Boots & Coots.

On February 16, 2010, representatives of Boots & Coots gave a management presentation to representatives of Halliburton, Baker Botts and Ernst & Young. The presentation focused on, among other things, Boots & Coots’ global presence, financial results, equipment, facilities, prospects and operations, as well as an assessment of how Boots & Coots might fit into Halliburton’s organizational structure.

On February 19, 2010, the Boots & Coots board of directors held a telephonic meeting, with the participation of a representative of Thompson & Knight, at which Mr. Winchester reported on the management presentations and the status of due diligence efforts. The board then discussed the Boots & Coots compensation committee’s annual compensation process which was then underway and the advisability of understanding the impact that existing compensation arrangements and current compensation determinations might have on the proposed transaction and the value that would be received by stockholders in the event that the transaction moved forward. The Chairman of the compensation committee indicated that he would endeavor to arrange a meeting with representatives of Halliburton to discuss these matters.

On February 24, 2010, Boots & Coots entered into an engagement letter with HFBE pursuant to which HFBE would prepare a financial analysis of the proposed transaction with a view towards advising the board as to its opinion of the fairness of the transaction, from a financial point of view, to the stockholders of Boots & Coots.

On February 26, 2010, representatives of Halliburton met with the compensation committee of Boots & Coots’ board of directors to discuss the proposed transaction. The members of the compensation committee informed Halliburton’s representatives that the committee was conducting its annual review process relating to compensation, including grants of equity awards, to Boots & Coots’ directors and employees. The members of the compensation committee inquired about whether equity grants made prior to closing a transaction with Halliburton would impact the $3.10 value of the consideration set forth in Halliburton’s proposal letter and inquired about how existing severance arrangements with Boots & Coots’ employees would be impacted by a proposed transaction with Halliburton. The representatives of Halliburton stated that any equity awards granted to Boots & Coots’ directors and employees, along with anything discovered in Halliburton’s due diligence review, would have an impact on the consideration paid in connection with a transaction. In addition, the representatives of Halliburton stated that no decision had been made with respect to the treatment of existing severance arrangements with Boots & Coots’ management and employees.

On March 1, 2010, the compensation committee of the Boots & Coots board of directors met with Longnecker & Associates, Boots & Coots’ compensation consultants, during its regularly scheduled annual review of short term and long term incentive awards and executive officer compensation. During the meeting, the committee discussed approaches to compensation in light of the discussions regarding a proposed transaction with Halliburton, including the magnitude and timing of changes in compensation and equity awards. The committee discussed, among other things, the risk that a definitive agreement would not be reached with Halliburton, the risk that a transaction might not be consummated even if a definitive agreement were executed, the lengthy process associated with consummating a transaction of the type proposed and the risks to Boots & Coots and its business from failing to adequately address employee compensation. In addition, the committee considered that any awards granted may accelerate the compensation received by recipients of the awards and impact the consideration received by stockholders if the transaction was consummated. After discussion, the committee elected to recommend to the full board certain awards to employees and outside directors and other changes to compensation that were consistent with the recommendations of Longnecker & Associates, and in line with Longnecker & Associates’ analysis of Boots & Coots’ peer group, and which were appropriate in order to attract and retain talented employees. At the regularly scheduled meeting of the full board later that day, the board of directors of Boots & Coots approved such awards and compensation.

During February and the first two days of March 2010, Halliburton worked with Baker Botts to prepare an initial draft of the merger agreement for the acquisition of Boots & Coots. On March 2, 2010, Baker Botts delivered a draft merger agreement to Thompson & Knight.

On March 10, 2010, the board of directors of Boots & Coots met with its legal and financial advisors. At the meeting a representative of Thompson & Knight reviewed with the board its fiduciary duties in the context of the proposed transaction. HFBE reviewed with the Boots & Coots board its financial analysis of the proposed transaction. In this regard, a representative of HFBE indicated that, based upon its analysis, the consideration to be paid by Halliburton in the proposed transaction was fair to the stockholders of Boots & Coots from a financial point of view and that HFBE was prepared to render an opinion to that effect at the appropriate time.

Also at the meeting, a representative of Thompson & Knight reviewed the terms of the proposed merger agreement, including a detailed review of the provisions of the draft merger agreement limiting Boots & Coots’ ability to solicit or consider potentially superior transactions, limiting the Boots & Coots board of directors’ ability to adversely change its recommendation of the merger and the merger agreement, restricting the board’s ability to terminate the merger agreement and requiring the payment of a termination fee. The representative of Thompson & Knight also reviewed proposed revisions to the merger agreement, including the addition of a “go-shop” provision and other changes to the provisions limiting the consideration of a superior

transaction and a reduction in the amount and timing of the payment of a termination fee. During the course of the presentation, the representative of Thompson & Knight responded to various questions regarding the merger agreement and the proposed transaction.

At this meeting, Boots & Coots’ management and board of directors again discussed the strategic rationale behind Halliburton’s interest in acquiring Boots & Coots, other potentially interested parties and the likelihood of securing a superior transaction by approaching other potential acquirers or initiating an auction process. The board concluded that a higher offer with a suitable transaction structure was not likely and also discussed the business risks associated with approaching other potential acquirers or initiating an auction process. Management also presented the board with a review of first quarter 2010 operations to date and reviewed its forecast for the first quarter and affirmed its previous forecast for the year. The board then met in executive session and considered the adequacy of the consideration being offered by Halliburton, the terms upon which the common stock of Halliburton would be valued, the terms of the merger agreement and the risks and uncertainties associated with the proposed transaction, including provisions in the merger agreement requiring certain officers of Boots & Coots to agree to employment with Halliburton on an ongoing basis as a condition of the closing of the transaction. The full board then convened and discussion ensued regarding the same topics. At the conclusion of the meeting the board directed Thompson & Knight to revise the merger agreement to incorporate the proposed revisions presented at the meeting and authorized management and Thompson & Knight to continue to negotiate the terms of the merger agreement with Baker Botts and Halliburton.

Later on March 10, 2010, Baker Botts and Thompson & Knight discussed Halliburton’s intention to retain certain officers of Boots & Coots after the closing of the proposed merger and Halliburton’s insistence upon the inclusion of a closing condition to that effect in the merger agreement. A representative of Thompson & Knight stated that Boots & Coots’ board of directors wanted to confirm that the terms of any such arrangement were clearly articulated to those officers in order to allow the board of directors to assess whether those officers were willing to join Halliburton. A representative of Baker Botts stated that the issue would be taken under advisement and noted that Halliburton was in the process of considering the employment and severance arrangements for such officers.

On March 12, 2010, Thompson & Knight delivered a revised draft of the merger agreement reflecting Boots & Coots’ initial comments thereon to Baker Botts.

On March 22, 2010, Baker Botts delivered a revised draft of the merger agreement reflecting Halliburton’s comments thereon to Thompson & Knight.

On March 26, 2010, representatives of Halliburton, Boots & Coots, Baker Botts and Thompson & Knight met to discuss the terms of the draft merger agreement circulated by Baker Botts on March 22, 2010. Among other things, the representatives discussed Halliburton’s and Boots & Coots’ respective positions regarding various provisions of the draft merger agreement and key open items, including


	•	the scope of representations, warranties and covenants of Boots & Coots,

	•	provisions relating to Boots & Coots’ ability to solicit a third party to make a proposal to acquire Boots & Coots,

	•	provisions relating to Boots & Coots’ ability to provide information to and have discussions with a third party that has made or makes a proposal to acquire Boots & Coots,

	•	conditions to closing the proposed merger, including the requirement that certain officers of Boots & Coots be employed by Halliburton post-closing,

	•	the circumstances under which a termination fee would be payable and the timing of the payment of any fee, and

	•	the amount of any termination fee.

In addition, Halliburton requested an extension of the exclusivity agreement dated January 27, 2010, originally for two weeks with an option for an additional two weeks in the event necessary for it to conclude

its due diligence investigation. After consulting with Douglas Swanson, Chairman of the Boots & Coots board of directors, Mr. Winchester proposed a ten-day extension.

On March 28, 2010, Halliburton and Boots & Coots executed an amendment to the exclusivity agreement that extended the period of exclusivity through April 9, 2010.

From March 29, 2010 through April 9, 2010, Halliburton’s and Boots & Coots’ respective management and legal advisors continued to exchange drafts of a merger agreement and to engage in negotiations regarding the terms of the proposed merger, including the issues noted above and employee and benefits matters.

On April 5, 2010, Michael Cheeseman of Halliburton telephoned Messrs. Winchester and Baetz to discuss the results of Halliburton’s due diligence and an adjustment to the proposed purchase price. Mr. Cheeseman informed Messrs. Winchester and Baetz that based on, among other things, the number of fully diluted shares of Boot & Coots common stock outstanding as compared to the number assumed in Halliburton’s January 27, 2010 proposal, as well as various items discovered during Halliburton’s due diligence investigation, Halliburton was reducing the proposed consideration to be paid in connection with the merger to a value of $3.00 per share of Boots & Coots common stock. All other terms of the proposal letter, including that at least 40% of the purchase price would be made up of Halliburton common stock and the balance in cash, remained the same. After discussion, Messrs. Baetz and Winchester indicated that the matter would be considered by the Boots & Coots board of directors.

During the morning of April 6, 2010, Mr. Winchester informed the Boots & Coots board of directors of Halliburton’s adjustment to the proposed purchase price and the stated bases therefor. Also on April 6, 2010, Messrs. Cheeseman and Baetz met to discuss the revised proposal. Mr. Baetz indicated that he thought the Boots & Coots board of directors would agree to a five cent reduction to $3.05 based on the increase in the number of fully diluted shares of Boots & Coots common stock but did not agree with the remaining five cent reduction that lowered the purchase price to $3.00. Mr. Cheeseman then informed Mr. Baetz that the $3.00 purchase price was Halliburton’s proposed price based upon the substantial completion of its due diligence investigation and subsequent discussions with and review by Halliburton’s senior management. Mr. Cheeseman stated that senior management would not recommend approval of the transaction to Halliburton’s board of directors at a purchase price above $3.00 and that if Boots & Coots wanted the Halliburton board of directors to consider the proposed transaction, Mr. Cheeseman needed to know that evening if Boots & Coots could consider a transaction at $3.00 per share of Boots & Coots common stock.

In the evening of April 6, 2010, Mr. Baetz telephoned Mr. Cheeseman and stated that Boots & Coots could consider a potential merger for a combination of Halliburton common stock and cash valued at $3.00 per share of Boots & Coots common stock.

From April 7 through April 9, 2010, Boots & Coots’ management and their separate legal counsel, and representatives of Halliburton, had discussions regarding the provisions of executive agreements to be entered into by and between Halliburton, on the one hand, and the executive officers of Boots & Coots, on the other hand, including an agreement under which those individuals would agree to elect to receive all Halliburton common stock in the merger with respect to the Boots & Coots common stock they hold and to not sell or otherwise dispose of any Halliburton common stock within one year of the closing of the merger. In addition, Halliburton’s and Boots & Coots’ respective management and legal advisors also negotiated the terms of certain amendments to the compensation, benefit and severance arrangements relating to the executive officers of Boots & Coots. See “— Interests of Certain Persons in the Merger that May be Different from Your Interests” beginning on page 60.

In the morning of April 9, 2010, the Halliburton board of directors convened a telephonic meeting to review and consider the proposed merger. Present at the meeting were members of Halliburton’s senior management and representatives of Baker Botts. At the meeting, Halliburton’s senior management briefed the board of directors on the key terms of the proposed merger and negotiations that had occurred since their last update, reviewed the strategic rationale for the transaction, reviewed recent financial results of Boots & Coots, provided an overview of the proposed arrangements with certain executive officers of Boots & Coots and recommended in favor of the merger on the terms presented. Representatives of Baker Botts discussed with

the board of directors certain material terms of the merger agreement and certain legal matters relating to the board of directors’ consideration of the proposed merger. Following consideration of the terms of the proposed merger and discussion among the directors, senior management and Baker Botts, the Halliburton board of directors unanimously approved the proposed merger and authorized management to enter into the merger agreement.

Also in the morning of April 9, 2010, a meeting of the board of directors of Boots & Coots was held, with all members of the board present in person or by telephone, to review and consider the proposed merger agreement. Present at the meeting were members of Boots & Coots’ senior management, a representative of Thompson & Knight and a representative of HFBE. At the meeting, management and the representative of Thompson & Knight briefed the board of directors on the key provisions of the proposed merger agreement and negotiations that had occurred since their last update. During the course of the briefing, the representative of Thompson & Knight responded to various questions regarding the merger agreement and the transaction. At the meeting, the representative of Thompson & Knight presented and discussed draft resolutions of the board and the compensation committee of the board with respect to the proposed transaction, including authorization for an amendment to the Boots & Coots stockholders rights plan (to exempt Halliburton from the operation of the rights plan).

At the meeting, a representative of HFBE reviewed with the Boots & Coots’ board of directors HFBE’s financial analysis of the proposed transaction that had been updated for, among other things, the proposed $3.00 purchase price. In this regard, HFBE rendered its oral opinion, which was confirmed in writing later in the day, that, based upon its analysis, the consideration to be paid by Halliburton in the proposed merger was fair, from a financial point of view, to the stockholders of Boots & Coots. Management of Boots & Coots then provided an overview of the proposed employment and compensation arrangements with certain executive officers of Boots & Coots. Management was excused from the meeting and the Boots & Coots board met in executive session and considered the adequacy of the consideration being offered to the Boots & Coots stockholders, particularly in light of the reduction of the proposed purchase price and the recent increase in the trading price of Boots & Coots common stock. During the executive session the board also discussed: the terms of the merger agreement; the risks and uncertainties associated with entering into the proposed transaction, including provisions that required certain officers of Boots & Coots to agree to employment with Halliburton on an ongoing basis as a condition of the closing of the transaction; and the prospects for Boots & Coots receiving a superior proposal given the limitations contained in the merger agreement. The board also discussed possible drivers of the increase in Boots & Coots’ stock price over the preceding two months, expectations for the stock price if no transaction was entered into and the impact on the stock price if Boots & Coots performed as projected in management’s forecast. Following the executive session, management, including Mr. Winchester, returned to the board meeting. During the executive session and in the board meeting, Mr. DiPaolo indicated that given his past employment with Halliburton and his continuing close personal relationships with various members of management of Halliburton, he felt he should abstain from voting to approve the merger and the merger agreement. Following additional consideration of the terms of the proposed merger and discussion among the directors, including a discussion with management of other ways to grow Boots & Coots and increase shareholder value and the practical and financial limitations on Boots & Coots’ ability to do so, the Boots & Coots board of directors, with Mr. DiPaolo abstaining, unanimously determined that the merger agreement and the transactions contemplated therein (including the merger) were advisable, fair and in the best interests of Boots & Coots and its stockholders, approved the merger agreement and the transactions contemplated therein and resolved (subject to the exceptions contained in the merger agreement) to recommend the adoption of the merger agreement by the stockholders of Boots & Coots, and authorized management to enter into the merger agreement. Also on April 9, 2010, a meeting of the compensation committee of Boots & Coots was held to review and approve the treatment of stock options, SARs and restricted stock as contemplated by the merger agreement.

In the evening of April 9, 2010, the merger agreement was executed by Halliburton, Gradient and Boots & Coots. Later that evening, Halliburton and Boots & Coots issued a joint press release announcing the signing of the merger agreement.

Reasons for the Merger — Boots & Coots

The Boots & Coots board of directors carefully evaluated the merger agreement and the transactions contemplated thereby and determined that the merger agreement and the transactions contemplated thereby, including the proposed merger, are advisable and fair to and in the best interests of Boots & Coots and its stockholders. In approving the merger and recommending that Boots & Coots stockholders vote to adopt the merger agreement, the Boots & Coots board of directors consulted with Boots & Coots’ management and legal and financial advisors and considered a number of factors, including the following:


	•	the current and historical market price of Boots & Coots common stock relative to the merger consideration, including the fact that the proposed merger consideration of $3.00 per share represented a premium of approximately:


	•	26% above the $2.38 closing price per share of Boots & Coots common stock on April 8, 2010, the business day prior to the date of the Boots & Coots board meeting to approve the merger;

	•	86% above the $1.61 closing price per share of Boots & Coots common stock on January 27, 2010, the date Halliburton submitted its proposal letter to acquire all of the outstanding stock of Boots & Coots; and

	•	107% above the $1.45 volume weighted average price per share of Boots & Coots common stock for the one year ended April 8, 2010;


	•	the Boot & Coots board of directors’ familiarity with, and understanding of, Boots & Coots’ business, assets, financial condition, results of operations, current business strategy and prospects and the potential stockholder value that might result from other alternatives available to Boots & Coots, including the alternative of remaining an independent public company and the potential for stockholders to share in any future earnings growth of Boots & Coots, in light of the continued costs, risks and uncertainties associated with continuing to operate as a public company;

	•	the merger consideration compared to (a) implied EBITDA multiples of similar companies, (b) comparable transactions based on EBITDA multiples of the acquired companies; and (c) discounted cash flow analyses of Boots & Coots and related implied values;

	•	the fact that the merger consideration per share of Boots & Coots common stock is generally fixed, with $1.73 payable in cash and $1.27 of Halliburton common stock valued based upon the Halliburton five day average price, which limits the exposure of Boots & Coots stockholders to fluctuations in the market price of Halliburton common stock;

	•	that Boots & Coots stockholders have the option to elect cash, Halliburton common stock or a mixture of cash and Halliburton common stock, subject to the proration features of the merger agreement;

	•	the Boots & Coots board of directors’ expectation that the merger will qualify as a tax free reorganization under the Code and that Boots & Coots stockholders may be eligible for tax free treatment on the Halliburton common stock, if any, they receive in the merger (see “Material U.S. Federal Income Tax Consequences of the Merger”);

	•	the current and historical financial condition and results of operations of Boots & Coots, and the prospects of Boots & Coots if it were to remain a publicly owned corporation in light of the competitive nature of the industry in which it operates; its limited financial resources and the challenges and costs associated with raising debt or equity capital; the business and financial risks affecting the industry and the regions in which Boots & Coots operates; current expectations regarding Boots & Coots’ future performance; the challenges associated with and limitations on Boots & Coots’ ability to expand its business; and the risks that Boots & Coots might not achieve its strategic objectives;

	•	HFBE’s financial presentation, including its opinion, dated April 9, 2010, to the Boots & Coots board of directors as to the fairness, from a financial point of view, of the merger consideration to be received by the stockholders of Boots & Coots, based upon and subject to the qualifications, limitations and assumptions stated in such opinion, as more fully described below under “— Opinion of Howard


		Frazier Barker Elliott, Inc.” The full text of the opinion of HFBE, setting forth the assumptions made, procedures followed, matters considered and limitations on the reviews undertaken in connection with such opinion, is attached as Annex B to this proxy statement/prospectus;


	•	the Boots & Coots board of directors’ view, in consultation with Boots & Coots’ management, that other potentially interested parties were unlikely to conclude an acquisition on terms more favorable to Boots & Coots’ stockholders;

	•	the business and other risks associated with an expanded or extended sale or auction process;

	•	the terms and conditions of the merger agreement and the course of negotiations thereof; the Boots & Coots board of directors considered in particular:


	•	the conditions to the closing of the merger, including the fact that the obligations of Halliburton and Gradient under the merger agreement are not subject to a financing condition, and the exceptions to the events and other effects that would constitute a material adverse effect on Boots & Coots;

	•	the structure of the transaction as a merger, requiring approval by Boots & Coots’ stockholders, which would result in detailed public disclosure and a relatively lengthy period of time prior to completion of the merger during which an unsolicited superior proposal could be brought forth;

	•	Boots & Coots’ right to engage in negotiations with, and provide information to, a third party that makes an unsolicited acquisition proposal, if the Boots & Coots board of directors determines in good faith, after consultation with its legal and financial advisors, that such proposal constitutes or is reasonably likely to result in a transaction that is more favorable to Boots & Coots’ stockholders than the merger and is reasonably likely to be completed on the terms proposed;

	•	Boots & Coots’ right to change its recommendation regarding the merger and terminate the merger agreement in order to accept a superior proposal, subject to certain conditions and payment of a $10.0 million termination fee to Halliburton (see “The Merger Agreement — Termination, Amendment and Waiver”);

	•	the Boots & Coots board of directors’ view, in consultation with its legal advisors, that the termination provisions of the merger agreement and the termination fee of $10.0 million payable by Boots & Coots to Halliburton under specified circumstances were customary and would not unduly deter a third party that was interested in acquiring Boots & Coots;

	•	subject to certain limitations, the obligation of Halliburton to use commercially reasonable efforts to obtain required regulatory approvals and clearances; and

	•	that Boots & Coots’ stockholders will be entitled to appraisal rights under Delaware law to the extent that they are required to accept cash consideration for their shares of Boots & Coots common stock (other than cash paid in lieu of fractional shares);


	•	the likelihood that the merger will be completed on the terms set forth in the merger agreement, including the fact that the Boots & Coots board of directors believed that Halliburton did not require any financing to consummate the merger; and

	•	based upon the advice of management after consultation with its legal counsel, that the regulatory approvals necessary to consummate the merger could likely be obtained without any material cost or burden.

The board of directors of Boots & Coots also considered a variety of risks and other potentially negative factors concerning the merger, including the following:


	•	that following Boots & Coots’ commencement of active merger negotiations with Halliburton and prior to the execution of the merger agreement, the Boots & Coots board of directors did not actively solicit


		indications of interest from other parties who might be interested in engaging in a transaction with Boots & Coots. In this regard, the Boots & Coots board of directors considered, among other factors:


	•	the Boots & Coots board of directors’ view that the pursuit of offers by third parties posed the risk of disruption to Boots & Coots’ customer and employee relationships and the risk that Halliburton would revoke its proposal, as further described under “— Background of the Merger”;

	•	the fact that Boots & Coots had discussions with certain third parties from time to time and the Boots & Coots board of directors’ view that the pursuit of offers by third parties was not likely to result in a transaction that would be superior for Boots & Coots’ stockholders; and

	•	that while Boots & Coots was unsuccessful in its efforts to negotiate “go-shop” provisions with Halliburton that would have permitted Boots & Coots to solicit interest from other potential buyers after the execution of the merger agreement, the merger agreement does permit Boots & Coots, under certain circumstances, to engage in negotiations with, and provide information to, a third party that makes an unsolicited acquisition proposal and to terminate the merger agreement to enter into an agreement in respect of a superior proposal, subject to certain conditions and the payment of a termination fee to Halliburton.


	•	that Boots & Coots’ executive officers and directors have interests in the merger that may be different from, or in addition to, those of Boots & Coots’ stockholders generally (see “— Interests of Certain Persons in the Merger that May be Different from Your Interests”);

	•	that, while the merger is expected to be completed, there is no assurance that all conditions to the parties’ obligations to complete the merger will be satisfied or waived and, as a result, it is possible that the merger might not be completed even if approved by Boots & Coots’ stockholders;

	•	the risks and costs to Boots & Coots if the merger is not completed, including the diversion of management and employee attention, potential employee attrition, the potential effect on Boots & Coots’ business and its relationships with suppliers, customers, joint venture partners and others, and the likely negative effect on the trading price of Boots & Coots common stock;

	•	the requirement that, unless the merger agreement is earlier terminated by Boots & Coots’ board of directors in response to a superior proposal, Boots & Coots may be required to submit the merger agreement for adoption by Boots & Coots’ stockholders even if the board withdraws its recommendation of the merger;

	•	that under the terms of the merger agreement, Boots & Coots must pay to Halliburton a termination fee of $10.0 million if the merger agreement is terminated under certain circumstances;

	•	the conditions to the closing of the merger, including regulatory approvals and the risk that unanticipated events or circumstances could lead to a breach of Boots & Coots’ representations or warranties or a failure to satisfy the conditions to closing, thus giving Halliburton the opportunity to terminate the merger agreement and receive reimbursement of its out-of-pocket expenses (up to $1.5 million) under certain circumstances;

	•	the restrictions on the conduct of Boots & Coots’ business prior to completion of the merger, requiring Boots & Coots to conduct its business only in the ordinary course, subject to specific limitations, which may delay or prevent Boots & Coots from undertaking business opportunities that may arise pending completion of the merger;

	•	the possible disruption to Boots & Coots’ business that might result from the announcement of the merger and the resulting distraction of the attention of Boots & Coots’ management and employees; and

	•	risks of the type and nature described under “Risk Factors.”

Boots & Coots’ board of directors considered all of these factors as a whole and, on balance, concluded that it supported a determination to approve the merger agreement and the merger and to recommend that the

Boots & Coots stockholders adopt the merger agreement. The foregoing discussion of the information and factors considered by the board of directors is not exhaustive, but Boots & Coots believes it includes the material factors considered by the Boots & Coots board of directors. In view of the wide variety of factors considered by the board of directors in connection with its evaluation of the proposed transaction and the complexity of these matters, the board of directors of Boots & Coots did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. The board of directors of Boots & Coots evaluated the factors described above and reached a consensus that the proposed transaction was advisable to and in the best interests of, Boots & Coots and its stockholders. In considering the factors described above and any other factors, individual members of the board of directors may have viewed factors differently or given different weights or merits to different factors.

The Boots & Coots board of directors recommends that Boots & Coots’ stockholders vote “FOR” adoption of the merger agreement.

Properly dated and signed proxies, and proxies properly submitted over the Internet and by telephone, will be so voted unless Boots & Coots’ stockholders specify otherwise.

Reasons for the Merger — Halliburton

In reaching a conclusion to approve the merger, the Halliburton board of directors consulted with Halliburton’s management, as well as legal advisors. In these consultations, the board considered a number of factors, including the following:


	•	the merger would expand Halliburton’s completion and production enhancement portfolio with the addition of Boots & Coots’ suite of pressure control and well intervention services;

	•	the addition of Boots & Coots’ service offerings to Halliburton’s portfolio is expected to help Halliburton improve full life cycle returns for its customers by further enabling integrated project workflows and improving reservoir recoveries;

	•	Boots & Coots’ strong international presence, especially in key markets in the Middle East, Africa and Asia, align well with Halliburton’s growth objectives;

	•	the merger provides the opportunity to combine Boots & Coots’ operations with Halliburton’s existing coiled tubing and hydraulic workover operations to create a new product service line that is expected to have a strong global presence and attractive growth prospects;

	•	Boots & Coots’ senior management has a demonstrated track record of growth, and will be managing the newly created Boots & Coots product service line following the transaction;

	•	the results of the business, legal and financial due diligence review of Boots & Coots’ businesses and operations;

	•	the board of director’s knowledge of Halliburton’s business, operations, financial condition, earnings and prospects and of Boots & Coots’ business, operations, financial condition, earnings and prospects, taking into account the results of Halliburton’s due diligence of Boots & Coots; and

	•	the terms and conditions of the merger agreement, including the following:


	•	Halliburton may be entitled to receive a $10.0 million termination fee from Boots & Coots if the merger is not consummated for certain reasons as more fully described in the section titled “Terms of the Merger Agreement — Termination, Amendment and Waiver” beginning on page 87;


	•	the conditions required to be satisfied prior to completion of the merger are customary, thereby increasing the likelihood of the consummation of the merger; and

	•	subject to certain exceptions, Boots & Coots is prohibited from taking certain actions that would be deemed to be a solicitation under the merger agreement, including solicitation, initiation, encouragement or facilitation of any inquiries or the making of any proposals for certain types of


		business combinations or acquisitions of Boots & Coots (or entering into any agreement for such business combination or acquisition of Boots & Coots or any agreement requiring Boots & Coots to abandon, terminate or fail to consummate the merger).

Financial Projections

Boots & Coots does not as a matter of course make public financial forecasts as to future revenues, earnings or other results, and Boots & Coots is especially cautious of making financial forecasts for extended periods due to the unpredictability of the underlying assumptions and estimates. However, for internal purposes and in connection with the process leading to the merger agreement, the management of Boots & Coots prepared certain projections of future financial and operating performance. The projections were prepared by Boots & Coots on a stand-alone basis and are not anticipated to be representative of financial and operating performance going forward, which may differ materially from the assumptions underlying the projections for Boots & Coots on a stand-alone basis. The projections are included in this proxy statement/prospectus because Boots & Coots provided such projections to its financial advisor, HFBE, in connection with the merger. A summary of this information is included below to give Boots & Coots’ stockholders access to non-public, unaudited prospective Boots & Coots information that was considered by Boots & Coots’ financial advisor for purposes of preparing its financial analysis and fairness opinion to the Boots & Coots board of directors.

Boots & Coots cautions you that uncertainties are inherent in prospective financial information of any kind. Neither Boots & Coots nor Halliburton nor any of their respective affiliates, advisors, officers, directors or representatives has made or makes any representation or can give any assurance to any Boots & Coots stockholder or any other person regarding the ultimate performance of Boots & Coots, whether independently or as a subsidiary of Halliburton, in relation to the summarized information set forth below.

The summarized projected financial information set forth below represents the most recent projections provided prior to the execution of the merger agreement to HFBE and the Boots & Coots board of directors. The inclusion of the following summarized projected financial information in this proxy statement/prospectus should not be regarded as an indication that Boots & Coots, Halliburton or their respective representatives considered or consider the projections to be an accurate prediction of future performance or events, and the summarized projected financial information set forth below should not be relied upon as such, nor regarded as a representation that such performance will be achieved.

The projections summarized below were prepared by, and are the responsibility of, the management of Boots & Coots in connection with the evaluation of the proposed merger or for internal planning purposes only and not with a view toward public disclosure or toward compliance with GAAP or the published guidelines of the SEC or the American Institute of Certified Public Accountants regarding financial projections. The projections were prepared on a basis consistent with historical accounting policies included in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Boots & Coots’ annual report on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2009, which is incorporated by reference in this proxy statement/prospectus. See “Where You Can Find More Information.” None of UHY LLP, Boots & Coots’ independent registered public accountants, KPMG LLP, Halliburton’s independent registered public accounting firm, or any other independent registered public accounting firm has compiled, examined or performed any procedures with respect to the prospective financial information contained in the projections and, accordingly, neither UHY LLP nor KPMG LLP expresses an opinion or any other form of assurance with respect thereto. The reports of UHY LLP incorporated by reference into this proxy statement/prospectus relate to Boots & Coots’ historical financial information. Such reports do not extend to the projections included below and should not be read to do so. The board of directors of Boots & Coots did not prepare, and does not give any assurance regarding, the summarized projected financial information.

The internal financial forecasts of Boots & Coots (upon which the projected financial information is based) are, in general, prepared solely for internal use to assist in various management decisions, including with respect to capital budgeting. Such internal financial forecasts are inherently subjective in nature and susceptible to

interpretation and the effects of intervening events and, accordingly, such forecasts may not be achieved. The internal financial forecasts also reflect numerous assumptions made by management, including various estimates and assumptions that may not be realized and are subject to significant variables, uncertainties and contingencies, all of which are difficult to predict and many of which are beyond the control of Boots & Coots. Important factors that may affect or cause the information below to differ from actual results include, but are not limited to, the factors referred to under the headings “Cautionary Statements Concerning Forward-Looking Statements” and “Risk Factors” in this proxy statement/prospectus and other risks described in Boots & Coots’ annual report on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2009, and in subsequent quarterly reports on Form 10-Q and current reports on Form 8-K. See “Where You Can Find More Information.” Accordingly, there can be no assurance that the assumptions made in preparing the internal financial forecasts upon which the projected financial information was based will prove accurate. There will be differences between actual and forecasted results, and the differences may be material. The risk that these uncertainties and contingencies could cause the assumptions to fail to be reflective of actual results is further increased by the length of time in the future over which these assumptions apply.

In developing the projections, Boots & Coots made numerous assumptions with respect to the projections for the periods shown, including:


	•	that global economic conditions and international markets would improve;

	•	that certain significant existing customers would sustain or improve business activity levels;

	•	that Boots & Coots would obtain new business opportunities with specific existing and prospective customers;

	•	that Boots & Coots would meet performance targets under existing contracts and successfully negotiate extensions of certain existing contracts;

	•	that Boots & Coots would be awarded specific, identified contracts in markets and that those contracts would generate forecasted revenue and gross margins;

	•	that Boots & Coots would be able to enter into targeted new domestic and international markets successfully;

	•	that Venezuelan operations and currency fluctuations would stabilize and that government instability would not interfere with Boots & Coots’ operations or business development efforts in any other international markets; and

	•	other general business, market and financial assumptions.

Boots & Coots provides services primarily to oil and natural gas exploration and development companies. Actual and projected market prices of oil and natural gas are therefore significant factors in determining business activity levels of Boots & Coots’ principal customer base and corresponding activity levels for Boots & Coots and its competitors.

The summarized projected financial information set forth below reflects Boots & Coots’ projected results for the years ending December 31, 2010, 2011 and 2012.


	2010E		2011E		2012E
	(In thousands except per share amounts)

Total consolidated revenue	$	233,271	$	263,653	$	307,796
EBITDA(1)	$	34,621	$	41,329	$	51,995
Diluted earnings per common share	$	0.13	$	0.17	$	0.23


(1)		Earnings before interest, income taxes, depreciation and amortization (“EBITDA”) is a non-GAAP financial measure, as it excludes amounts or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with GAAP in financial statements. Non-GAAP financial measures disclosed by management are provided as additional information to investors in order to provide them with an alternative method for assessing Boots & Coots’


		financial condition and operating results. These measures are not in accordance with, or a substitute for, GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. EBITDA should not be considered in isolation or as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP or as a measure of a company’s profitability or liquidity. Management believes that EBITDA may provide additional information with respect to Boots & Coots’ performance or ability to meet its debt service and working capital requirements.

At the time the projected financial information set forth above was prepared, the projections represented the best estimates and judgments of Boots & Coots’ management with respect to the potential future financial performance of Boots & Coots. While the projected financial information set forth above was prepared in good faith, no assurance can be given regarding future events or future performance.

Furthermore, the summarized, projected financial information does not necessarily reflect revised prospects for Boots & Coots’ business, changes in general business or economic conditions, or any other transactions or events that have occurred since the date the information was prepared or that may occur and that were not anticipated at the time the information was prepared. The information summarized herein does not reflect the effects of the merger, which is likely to cause actual results to differ materially. Since the preparation of the information, among other developments, Boots & Coots has made publicly available its results of operations for the year ended December 31, 2009 and the quarters ended March 31, 2010 and June 30, 2010. Stockholders should review Boots & Coots’ 2009 annual report on Form 10-K, as amended by Form 10-K/A, and its quarterly reports on Form 10-Q for the quarters ended March 31, 2010 and June 30, 2010 to obtain this information. See “Where You Can Find More Information.”

BOOTS & COOTS DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN IT WAS FORMULATED OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IF ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH PROSPECTIVE FINANCIAL INFORMATION ARE NO LONGER APPLICABLE OR APPROPRIATE.

Opinion of Howard Frazier Barker Elliott, Inc.

Boots & Coots retained HFBE to render an opinion to the Boots & Coots board of directors as to the fairness, from a financial point of view, of the consideration to be received by the Boots & Coots common stockholders in connection with the merger. On April 9, 2010, at a meeting of the Boots & Coots board of directors, HFBE delivered an oral opinion and subsequently on April 9, 2010 delivered its written opinion that stated, as of the date of the opinion and based upon and subject to various assumptions and limitations described in the opinion, the consideration to be received by the Boots & Coots common stockholders in the merger was fair, from a financial point of view, to such common stockholders.

The full text of HFBE’s written opinion to the Boots & Coots board of directors, which describes, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken, is attached as Annex B to this proxy statement/prospectus. The following summary of HFBE’s opinion is qualified in its entirety by reference to the full text of the opinion. HFBE delivered its opinion to the Boots & Coots board of directors for use in connection with the board of directors’ evaluation of the merger consideration from a financial point of view. HFBE’s opinion does not address any other aspect of the merger and does not constitute a recommendation to any stockholder as to how to vote with respect to the proposed merger or any related matter. Holders of Boots & Coots common stock are encouraged to read HFBE’s opinion for a discussion of the procedures followed, factors considered, assumptions made and qualifications and limitations of the review undertaken by HFBE in connection with its opinion.

In connection with rendering the opinion described above and performing its related financial analyses, HFBE reviewed, among other things:


	•	the draft of the Agreement and Plan of Merger dated April 8, 2010;


	•	the proposal letter from Halliburton to Boots & Coots dated January 27, 2010;

	•	certain publicly available filings by Boots & Coots with the SEC, including annual reports on Form 10-K for the years ended December 31, 2005 through 2009;

	•	internal projected financial statements for the years ending December 31, 2010 through 2012 as prepared by Boots & Coots management;

	•	current and historical prices and trading volumes of the common stock of Boots & Coots;

	•	certain other publicly available information concerning Boots & Coots;

	•	certain publicly available information with respect to certain publicly traded companies that HFBE deemed comparable to Boots & Coots;

	•	certain publicly available data relating to merger and acquisition transactions involving companies and assets HFBE deemed comparable to those of Boots & Coots; and

	•	such other matters as HFBE deemed necessary, including an assessment of general economic, market, and monetary conditions.

In addition, HFBE held discussions with members of the management of Boots & Coots regarding the business, operations, financial condition, and prospects of Boots & Coots. HFBE discussed with Boots & Coots’ management the financial projections provided by management listed above, including factors that could cause such projections to differ materially from actual performance or results. HFBE also performed such other financial studies, analyses and investigations as it deemed appropriate. Boots & Coots’ board of directors did not impose upon HFBE any limitations with respect to the investigations made or procedures followed by it in rendering its opinion.

In arriving at its opinion, HFBE relied on the accuracy and completeness of all information made available to HFBE by Boots & Coots. HFBE assumed, with Boots & Coots’ consent and did not independently verify, that the financial projections used in rendering its opinion had been reasonably prepared and were based on the best currently available estimates and judgments of the management of Boots & Coots. HFBE did not express an opinion with respect to such projections or the assumptions on which they were based. None of Boots & Coots, Halliburton, HFBE or any other person assumes responsibility if future results are materially different from those discussed. HFBE did not undertake an independent appraisal of the assets of Boots & Coots. HFBE also relied upon and assumed, without independent verification, that the merger will be consummated in a timely manner in accordance with the terms described in the merger agreement and documents provided to it by Boots & Coots, without any material amendments or modifications thereto.

HFBE’s opinion is limited to the fairness, from a financial point of view, of the consideration to be received by the Boots & Coots common stockholders in the merger and does not address the relative merits of the merger or any other transaction or business strategies discussed by the Boots & Coots board of directors as alternatives to the merger or the decision of the Boots & Coots board of directors to proceed with the merger, nor the fairness of any portion or aspect of the merger to the holders of any class of securities, creditors or other constituencies of Boots & Coots, or to any other party, except as set forth in HFBE’s opinion. HFBE was not requested to and did not solicit third party indications of interest in providing capital to or acquiring all or any part of Boots & Coots. The type and amount of consideration payable in the merger was determined based on arm’s-length negotiations between Boots & Coots and Halliburton, and the decision to enter into the merger was solely determined by the board of directors of Boots & Coots. HFBE’s opinion and financial analyses were only one of many factors considered by the board of directors of Boots & Coots in its evaluation of the merger.

The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant quantitative and qualitative methods of financial analysis and the application of those methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to partial analysis or summary description. Furthermore, in arriving at its opinion, HFBE did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and

relevance of each analysis or factor. Accordingly, HFBE believes that its analysis must be considered as a whole and that considering any portion of such analysis and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, HFBE made numerous assumptions with respect to the industry, general business and economic conditions and other matters, many of which are beyond the control of Boots & Coots or Halliburton. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values which may be significantly more or less favorable than as set forth therein. In addition, analyses relating to the value of the business do not purport to be appraisals or to reflect the prices at which businesses may actually be sold.

HFBE’s opinion was based on economic, market, financial and other conditions as they existed as of the date of the opinion, and on the information made available to HFBE as of the date of the opinion. Although subsequent developments may affect the conclusion reached in the opinion, HFBE has no obligation to update, revise, or reaffirm its opinion. HFBE’s opinion has been reviewed and authorized for issuance by HFBE’s fairness committee.

The following represents a brief summary of the material financial analyses presented by HFBE to the Boots & Coots board of directors in connection with rendering its opinion. The summary set forth below does not purport to be a complete description of the analyses performed by HFBE, nor does the order of analyses described represent relative importance or weight given to those analyses by HFBE. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are not alone a complete description of HFBE’s analyses. HFBE further believes that selecting portions of its analyses and the factors considered or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying HFBE’s analyses and opinion.

Historical Trading Prices

As of April 6, 2010, Boots & Coots had approximately 81.8 million shares of common stock outstanding with an aggregate equity market capitalization of $196.3 million based on the closing price per share of Boots & Coots common stock of $2.40. HFBE reviewed the average of the closing prices per share of Boots & Coots common stock, as well as the low and high closing price per share of Boots & Coots common stock, over the 10-day, 30-day, three-month, six-month and one-year periods ending on April 6, 2010. The results of this review are noted in the table below.


			Average of
	Highest Closing		Closing		Lowest Closing
	Price Over		Prices Over		Price Over
Specified Period	Specified Period		Specified Period		Specified Period

10-day	$	2.48	$	2.42	$	2.36
30-day		2.48		2.21		2.03
90-day		2.48		1.87		1.50
Six months		2.48		1.67		1.29
One year		2.48		1.54		1.15

Value of the Consideration

The merger consideration offered to Boots & Coots’ common stockholders is a mixture of $1.73 in cash and a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $1.27 by the Halliburton five-day average price, for each share of Boots & Coots common stock, subject to modification in order to achieve the intended tax consequences of the merger. Alternatively and subject to proration, Boots & Coots common stockholders may elect to receive the merger consideration comprised of either (i) $3.00 in cash for each share of Boots & Coots common stock they own or (ii) a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $3.00 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. For the purposes of its analysis, HFBE used the implied merger consideration of $3.00 per share of

Boots & Coots common stock, which accounts for both the cash and stock components of the merger consideration. Based on 84.1 million diluted shares (as determined using the treasury method) of Boots & Coots common stock outstanding as of April 6, 2010 and the implied consideration of $3.00 per share of Boots & Coots common stock, the aggregate value of the consideration offered to Boots & Coots stockholders was $252.2 million. After adding outstanding net debt of $28.2 million as of February 28, 2010, the enterprise value of Boots & Coots implied in the merger was approximately $280.3 million.

Valuation Analysis

Selected Companies Analysis. Using publicly available information, HFBE compared selected financial information for Boots & Coots and the following seven selected publicly traded companies in the oilfield service industry:


	•	Allis-Chalmers Energy, Inc.

	•	Basic Energy Services, Inc.

	•	Complete Production Services, Inc.

	•	Key Energy Services, Inc.

	•	Oil States International, Inc.

	•	RPC, Inc.

	•	Superior Energy Services, Inc.

For each of the selected companies, HFBE reviewed, among other things, the ratio of enterprise value, which was calculated as diluted equity value based on closing stock prices as of April 6, 2010, plus debt, less cash and cash equivalents, as a multiple of the 2009 and estimated 2010 (“2010E”) and 2011 (“2011E”) EBITDA (earnings before interest expense, tax expense, depreciation and amortization). Estimated financial data of the selected publicly traded companies were based on publicly available research analysts’ estimates, public filings, and other publicly available information. Estimated financial data of Boots & Coots were based on Boots & Coots management’s forecasts. The multiples and ratios for Boots & Coots were calculated based on using (i) the $2.40 closing price per share of Boots & Coots common stock on April 6, 2010 and (ii) the merger consideration of $3.00 per share of Boots & Coots common stock.

For Boots & Coots, HFBE applied a range of selected multiples derived from the selected companies of 2009 and estimated 2010 and 2011 EBITDA to corresponding financial data of Boots & Coots in order to derive implied per share equity value reference ranges for Boots & Coots’ common stock. HFBE selected enterprise value multiple ranges of 8.00x to 10.00x 2009 EBITDA, 6.75x to 7.50x management’s 2010E EBITDA, and 5.25x to 5.75x management’s 2011E EBITDA. This analysis indicated the following implied per

share equity value reference ranges for Boots & Coots’ common stock, as compared to the merger consideration:

No company utilized in the selected companies analysis is identical to Boots & Coots. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the enterprise values, calculated as described above, or other values of the companies to which Boots & Coots was compared. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degrees of operational risk between Boots & Coots and the selected companies included in the selected companies analysis.

Selected Transactions Analysis. HFBE researched various merger and acquisition transactions involving companies that operate in the oilfield service industry. HFBE reviewed the purchase prices and implied transaction multiples for the following selected transactions:


Announcement Date	Acquiror	Target

February 21, 2010	Schlumberger Limited	Smith International Incorporated
December 11, 2009	Superior Energy Services, Inc.	Hallin Marine Subsea International PLC
August 31, 2009	Baker Hughes Incorporated	BJ Services Company
June 1, 2009	Cameron International Corp.	NATCO Group, Inc.
June 8, 2008	Precision Drilling Trust	Grey Wolf Incorporated
June 3, 2008	Smith International Incorporated	W-H Energy Services, Inc.
May 5, 2008	First Reserve Corp./Schlumberger Limited	Saxon Energy Services, Inc.
February 22, 2008	First Reserve Corp.	CHC Helicopter Corp.
December 16, 2007	National Oilwell Varco	Grant Prideco Incorporated
June 11, 2007	Cal-Dive International, Inc.	Horizon Offshore Incorporated

HFBE reviewed the implied enterprise values in the selected transactions as a multiple of the target company’s EBITDA for the period covering the last twelve calendar months (LTM) preceding the announcement date of the transaction. All multiples for the selected transactions were based on publicly available information at the time of announcement of the particular transaction.

The following table summarizes the multiples of all of the selected transactions, with the implied multiples for the merger presented below.


	Enterprise
	Value

Mean		9	.0 x
Median		9	.4 x
25th Percentile		6	.7 x
Lowest		5	.5 x
Boots & Coots
Based on merger consideration ($3.00/share)		11	.1 x

HFBE applied a range of selected multiples derived from the transactions to the 2009 EBITDA of Boots & Coots in order to derive implied per share equity value reference ranges for Boots & Coots’ common stock. HFBE selected an enterprise value multiple range of 7.50x to 9.50x 2009 EBITDA. This analysis

indicated the following implied per share equity value reference ranges for Boots & Coots, as compared to the merger consideration:


Implied per Share Equity Value Reference Range	Merger
for Boots & Coots Based on 2009 EBITDA	Consideration

$1.96-$2.57	$	3.00

No company or transaction utilized in the selected transaction analysis is identical to Boots & Coots or the merger and, accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the acquisition or other values of the companies, business segments or transactions to which Boots & Coots and the merger were compared. In evaluating the selected transactions and multiples, HFBE made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other factors, many of which are beyond the control of Boots & Coots or Halliburton. HFBE also noted that the merger and acquisition transaction environment changes over time due to macroeconomic factors such as interest rate and equity market fluctuations and microeconomic factors such as industry results and growth expectations. In particular, current and forecasted energy prices significantly affect the merger and acquisition market for oilfield service companies.

Discounted Cash Flow Analysis. HFBE performed a discounted cash flow analysis of Boots & Coots on a stand-alone basis using financial forecasts and estimates prepared by Boots & Coots’ management for fiscal years ending December 31, 2010 to 2012. HFBE calculated a range of implied present values as of March 31, 2010 of the stand-alone, unlevered, after-tax, cash flows that Boots & Coots was forecasted to generate from April 1, 2010 through December 31, 2012 using discount rates ranging from 13.5 percent to 15.9 percent. HFBE also calculated terminal values for Boots & Coots, as of December 31, 2012, using terminal multiples ranging from 6.0 to 7.5 times estimated EBITDA for fiscal year ending December 31, 2012. The estimated terminal values were then discounted to present value as of March 31, 2010 using the discount rates ranging from 13.5 percent to 15.9 percent. For purposes of this analysis, HFBE used the number of diluted shares of Boots & Coots common stock as of April 6, 2010 calculated using the treasury method. The discounted cash flow analysis indicated the following implied equity value per share reference range of Boots & Coots common stock, as compared to the merger consideration:


	Merger
Implied per Share Equity Value Reference Range for Boots & Coots	Consideration

$2.27 — $3.05	$	3.00

Other Factors

HFBE also reviewed, for informational purposes, certain other factors, including:


	•	historical trading prices and volume of Halliburton common stock during the one-year period ended April 6, 2010;

	•	projected EBITDA and earnings for Boots & Coots as estimated by selected research analysts; and

	•	control premiums paid in selected precedent transactions involving companies with stock prices greater than $1.00 per share completed between January 1, 1999 and December 31, 2009.

Miscellaneous

The discussion set forth above is a summary of the material financial analyses presented by HFBE to the Boots & Coots board of directors in connection with its opinion and is not a comprehensive description of all analyses undertaken by HFBE in connection with its opinion. Subject to the limitations on the review undertaken by HFBE, the assumptions and qualitative judgments made by HFBE and other factors stated in its opinion and referred to above, the implied per share equity value reference ranges for Boots & Coots derived using the various valuation methodologies discussed above supported HFBE’s conclusion that the

consideration to be received by the Boots & Coots common stockholders in the merger was fair, from a financial point of view, to the Boots & Coots common stockholders.

HFBE is a nationally recognized business valuation and investment banking firm with expertise in, among other things, valuing businesses and securities and rendering fairness opinions. HFBE is continually engaged in the valuation of businesses and securities in connection with mergers and acquisitions, private placements of equity and debt, employee stock ownership plans, and other general corporate purposes. Boots & Coots selected HFBE because of its experience and expertise in performing valuation and fairness opinion analyses. HFBE has received a fee of $150,000 for its services to Boots & Coots. No additional fee or compensation for services will be paid to HFBE in connection with or upon completion of the merger. HFBE has been reimbursed by Boots & Coots for its out-of-pocket expenses incurred in connection with providing its services to Boots & Coots, and Boots & Coots will indemnify HFBE for certain liabilities related to or arising out of the engagement, including liabilities under federal securities laws. During the two years preceding the date of this opinion, HFBE has not provided any services to and has not received any compensation from Boots & Coots, Halliburton, or their respective affiliates. HFBE may in the future provide financial advisory, investment banking, or other services to Boot & Coots, Halliburton, or their respective affiliates for which it would expect to receive compensation.

Accounting Treatment

If the merger is completed, Halliburton will account for the merger using the acquisition method of accounting under U.S. GAAP. Halliburton will record net tangible and identifiable intangible assets acquired and liabilities assumed from Boots & Coots at their respective fair values at the date of the completion of the merger. Any excess of the purchase price, which in the case of shares of Halliburton common stock issued as consideration will equal the market value on the date of the completion of the merger, over the net fair value of such assets and liabilities will be recorded as goodwill.

The financial condition and results of operations of Halliburton after completion of the merger will reflect Boots & Coots’ balances and results after completion of the merger but will not be restated retroactively to reflect the historical financial condition or results of operations of Boots & Coots. The earnings of Halliburton following the completion of the merger will reflect acquisition accounting adjustments, including the effect of changes in the carrying value for assets and liabilities on depreciation and amortization expense. Intangible assets with indefinite useful lives and goodwill will not be amortized but will be tested for impairment at least annually, and all assets including goodwill will be tested for impairment when certain indicators are present. If in the future, Halliburton determines that tangible or intangible assets (including goodwill) are impaired, Halliburton would record an impairment charge at that time

Listing of Halliburton Common Stock and Delisting and Deregistration of Boots & Coots Common Stock

Application will be made to have the shares of Halliburton common stock to be issued in the merger approved for listing on the NYSE, where Halliburton common stock is currently traded, upon issuance.

If the merger is completed, Boots & Coots common stock will be delisted from the NYSE Amex and deregistered under the Exchange Act.

Restrictions on Sales of Shares of Halliburton Common Stock Received in the Merger

The shares of Halliburton common stock to be issued in connection with the merger will be registered under the Securities Act and will be freely transferable, except for shares of Halliburton common stock issued to any person who is deemed to be an “affiliate” of Halliburton after the effective time of the merger. Boots & Coots stockholders who become affiliates of Halliburton as a result of the merger, if any, may not sell any of the shares of Halliburton common stock received by them in connection with the merger except pursuant to an effective registration statement under the Securities Act covering the resale of those shares or any applicable exemption under Rule 144 or otherwise under the Securities Act.

Opinions as to Material U.S. Federal Income Tax Consequences of the Merger

It is a condition to the closing of the merger that Baker Botts L.L.P. and Thompson & Knight LLP deliver opinions, dated as of the date of closing, to Halliburton and Boots & Coots, respectively, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

Each opinion will be based on certain factual representations, assumptions and certifications contained in certificates signed by duly authorized officers of Halliburton and Boots & Coots to be delivered at closing. An opinion of counsel represents counsel’s best legal judgment and is not binding on the Internal Revenue Service, and there can be no assurance that following the merger the Internal Revenue Service will not challenge the legal conclusions expressed in the opinions. Please review carefully the information under the caption “Material U.S. Federal Income Tax Consequences of the Merger” for a description of the material U.S. federal income tax consequences of the merger.

Board of Directors and Management of Halliburton Following the Merger

Halliburton’s directors and executive officers will remain the same following the merger as they are immediately before the merger becomes effective.

Interests of Certain Persons in the Merger that May be Different from Your Interests

Treatment of Equity Awards

The merger agreement provides that each option to purchase shares of Boots & Coots common stock and each SAR that is outstanding immediately prior to the completion of the merger, whether or not then exercisable or vested, will fully vest and will be converted into an obligation of Gradient to pay the holder thereof an amount in cash equal to the product of (1) the number of shares of Boots & Coots common stock subject to the option or SAR, as applicable, and (2) the excess, if any, of $3.00 over the exercise price per share previously subject to such option or SAR. In addition, the merger agreement provides that each outstanding award of restricted stock granted by Boots & Coots pursuant to an employee benefit plan will become fully vested, and each holder has the right to make the same elections as described below in “Terms of the Merger Agreement — Per Share Merger Consideration.”

The following table sets forth information concerning options and SARs relating to Boots & Coots common stock and restricted stock held by Boots & Coots’ executive officers and directors as of July 27, 2010.

Future Employment by Halliburton

In connection with Boots & Coots’ entry into the merger agreement, Jerry L. Winchester and Dewitt H. Edwards have each entered into an executive agreement with Halliburton Energy Services, Inc., a wholly owned subsidiary of Halliburton, which we refer to herein as Halliburton Energy, under which such executive will be employed by Halliburton Energy if the merger is completed, and will have the right to receive a severance payment if his employment by Halliburton Energy thereafter terminates under certain circumstances.

Executive Agreement with Jerry L. Winchester. Jerry L. Winchester, Boots & Coots’ Chief Executive Officer, has entered into an executive agreement with Halliburton Energy that will become effective at the time of the closing of the merger. If the merger is not completed, the executive agreement will be of no force or effect.

Pursuant to the executive agreement, Mr. Winchester will serve as Vice President, Product Service Line of Halliburton Energy. Mr. Winchester will receive an initial annual base salary of $300,000, which may be increased thereafter from time to time with the approval of the chief executive officer of Halliburton or his

delegate. The initial annual base salary may not be decreased without the written consent of Mr. Winchester, unless comparable reductions in salary are effective for all similarly situated executives of Halliburton Energy. In addition, Mr. Winchester will be granted (i) a merger closing award of 45,000 shares of Halliburton restricted common stock to vest one-third annually over a three-year period, (ii) 5,600 shares of Halliburton restricted common stock to vest one-third annually over a three-year period, and (iii) nonqualified stock options to purchase 6,800 shares of Halliburton common stock to vest one-third annually over a three-year period.

Pursuant to his executive agreement, provided his employment with Halliburton Energy commences on or before September 1, 2010, Mr. Winchester will be entitled to participate in Halliburton’s Annual Performance Pay Plan, or the Performance Pay Plan, for the 2010 plan year, with a maximum payout equal to 90% of annual base salary, and will be nominated for participation in Halliburton’s Performance Unit Program for the 2010 cycle, with a maximum payout equal to 90% of annual base salary. The 2010 awards, if any, will be prorated for the effective date of employment. If Mr. Winchester’s employment commences after September 1, 2010, he will participate in both of those plans effective January 1, 2011.

If Mr. Winchester’s employment is terminated by Halliburton Energy without cause or Mr. Winchester elects to terminate his employment for good reason, then Mr. Winchester will be entitled to:


	•	a payment equal to one year of annual base salary payable no later than 60 days following termination of employment; and

	•	a payment equal to the value of the unvested portion of the merger closing award of 45,000 shares of Halliburton restricted common stock and any other unvested shares of Halliburton restricted stock, provided he has complied with the one-year non-competition and non-solicitation provisions of his executive agreement, payable on the sixtieth day following the one-year anniversary of his termination of employment.

Mr. Winchester will not be entitled to receive the benefits set forth above if his employment is terminated as a result of death, retirement, permanent disability, voluntary termination or for cause. “Cause” means any of the following: (i) Mr. Winchester’s gross negligence or willful misconduct in the performance of his duties and services pursuant to the executive agreement; (ii) Mr. Winchester’s final conviction of a felony; (iii) a material violation of Halliburton’s code of business conduct; or (iv) Mr. Winchester’s material breach of any material provision of the executive agreement that remains uncorrected for 30 days following written notice of such breach by Halliburton Energy.

“Good reason” is generally defined as a termination of employment by Mr. Winchester because of a material breach by Halliburton Energy of any material provision of the executive agreement, provided that (i) Mr. Winchester provides written notice to Halliburton Energy of the circumstances he claims constitute good reason within 90 calendar days of the first to occur of such circumstances, (ii) such breach remains uncorrected for 30 calendar days following written notice, and (iii) Mr. Winchester’s termination occurs within 180 calendar days after the date that the circumstances Mr. Winchester claims constitute good reason first occurred.

As a condition to receiving the benefits described above, Mr. Winchester will be required to execute a general release of claims. Also, upon termination of Mr. Winchester’s employment with Halliburton Energy, Mr. Winchester will be subject to non-competition and non-solicitation obligations for one year.

Executive Agreement with Dewitt H. Edwards. Dewitt H. Edwards, Boots & Coots’ Chief Operating Officer, has entered into an executive agreement with Halliburton Energy that will become effective at the time of the closing of the merger. If the merger is not completed, the executive agreement will be of no force or effect.

Pursuant to the executive agreement, Mr. Edwards will serve as Senior Director, Global Operations of Halliburton Energy. Mr. Edwards will receive an initial annual base salary of $225,000, which may be increased thereafter from time to time with the approval of the chief executive officer of Halliburton or his delegate. The initial annual base salary may not be decreased without the written consent of Mr. Edwards,

unless comparable reductions in salary are effective for all similarly situated executives of Halliburton. In addition, Mr. Edwards will be granted (i) a merger closing award of 26,000 shares of Halliburton restricted common stock to vest one-third annually over a three-year period, (ii) 4,600 shares of Halliburton restricted common stock to vest one-third annually over a three-year period, and (iii) nonqualified stock options to purchase 7,500 shares of Halliburton common stock to vest one-third annually over a three-year period.

Pursuant to his executive agreement, provided his employment with Halliburton Energy commences on or before September 1, 2010, Mr. Edwards will participate in the Performance Pay Plan for the 2010 plan year with a maximum payout equal to 60% of annual base salary, prorated for the effective date of employment. If Mr. Edwards’ employment commences after September 1, 2010, he will participate in that plan effective January 1, 2011.

If Mr. Edwards’ employment is terminated by Halliburton Energy without cause or Mr. Edwards elects to terminate his employment for good reason, then Mr. Edwards will be entitled to:


	•	a payment equal to one year of annual base salary payable no later than 60 days following termination of employment; and

Mr. Edwards will not be entitled to receive the benefits set forth above if his employment is terminated as a result of death, retirement, permanent disability, voluntary termination or for cause. The terms “cause” and “good reason” have the same meanings as in Mr. Winchester’s executive agreement, as described above.

As a condition to receiving the benefits described above, Mr. Edwards will be required to execute a general release of claims.

Change of Control Arrangements

Boots & Coots Incentive Plans. The consummation of the merger will be considered a “change in control” or “change of control” transaction for purposes of Boots & Coots’ 2000 Long Term Incentive Plan (“2000 LTIP”), 2004 Long Term Incentive Plan (“2004 LTIP”) and 2006 Non-Employee Director Stock Incentive Plan (“Director Plan”) under which the Compensation Committee of Boots & Coots’ board of directors (or the board of directors in the case of the Director Plan) has granted incentive awards in the form of stock options, SARs and restricted stock to certain officers, employees, and directors of Boots & Coots and its affiliates. Under the 2000 LTIP and the Director Plan, a change in control results in immediate vesting of all then outstanding incentive awards that have not previously vested. The 2004 LTIP is similar to the 2000 LTIP and Director Plan, but the 2004 LTIP is considered a “double-trigger” plan because it provides for accelerated vesting of awards only if there is both a change in control and a termination of employment. Under the 2004 LTIP, a change in control combined with the termination of the employment of an award holder within one year of the change in control results in immediate vesting of all then outstanding incentive awards that have not previously vested. The merger agreement calls for the cash-out of vested and unvested stock options and SARs and full vesting of all restricted stock awards regardless of whether the holder also experiences a termination of employment. See “— Treatment of Equity Awards.”

Employment and Severance Agreements. Each of Messrs. Winchester and Edwards has an employment agreement with Boots & Coots, while Cary Baetz, Boots & Coots’ Chief Financial Officer, has a severance agreement with Boots & Coots. The consummation of the merger will be considered a change in control under these employment and severance agreements. With respect to each of these agreements, if a change in control occurs during the term of the agreement and the employee (i) is terminated by Boots & Coots for any reason other than for cause on or within one year following the change in control or (ii) terminates his employment

for good reason within one year following the change in control, then the employee is entitled to receive the following:


	•	cash equal to two times (for Messrs. Edwards and Baetz) or 2.5 times (for Mr. Winchester) gross annual salary and bonus;

	•	continued medical insurance coverage for up to two years (for Messrs. Edwards and Baetz) or 2.5 years (for Mr. Winchester);

	•	accelerated vesting of all outstanding restricted stock, options and other awards with respect to equity interests in Boot & Coots; and

	•	an additional payment to “gross up” the employee for the amount, if any, of excise tax imposed under the golden parachute provisions of Section 4999 of the Code with respect to any change in control payments and benefits, such that after payment of all income, excise and other applicable taxes on the gross-up payment, the employee will retain an amount equal to the excise tax imposed on any change in control payments and benefits.

The term “cause” means the executive (i) has engaged in gross negligence or willful misconduct in the performance of his duties, (ii) has willfully refused without proper legal reason to perform his duties, (iii) has materially breached any material provision of his agreement, (iv) commits, is arrested or officially charged with any felony or any crime involving moral turpitude, which, in the good faith opinion of Boots & Coots, would impair the executive’s ability to perform his duties or would impair the business reputation of Boots & Coots or (v) the executive misappropriates any funds or property of Boots & Coots.

Messrs. Edwards’, Winchester’s and Baetz’s ability to terminate employment with Boots & Coots for “good reason” as referenced above generally refers to (i) a material breach by Boots & Coots of any material provision of the respective agreement, (ii) a substantial and material reduction in the nature or scope of the executive’s duties or responsibilities, (iii) the assignment to the executive of duties and responsibilities that are materially inconsistent with his position, or (iv) with respect to Mr. Edwards, a permanent re-location of the executive without his approval to an office outside of Harris County, Texas.

Waiver, Election and Lock-Up Agreements. As required by the merger agreement, Messrs. Winchester and Edwards have entered into Waiver Agreements with Boots & Coots whereby they have agreed to irrevocably relinquish and waive any and all rights and claims they may have pursuant to their employment agreements in exchange for (i) the right to receive lump sum cash payments equal to the cash amounts that otherwise would be payable to them under their respective employment agreements in respect of cash severance and benefit continuation upon a change in control and immediate termination other than for cause or resignation for good reason and (ii) Halliburton’s express assumption of Boots & Coots’ commitment to provide additional payments to them in the event any excise taxes are imposed under the golden parachute provisions of Section 4999 of the Code as a result of a change in control. With respect to Mr. Winchester, the waiver payment is an amount to be determined that is not less than $1,000,000 and not more than $2,500,000. With respect to Mr. Edwards, the waiver payment is an amount to be determined that is not less than $567,000 and not more than $1,247,400. The specific amount payable to each of Mr. Winchester and Mr. Edwards will be determined once the incentive compensation payable to them by Boots & Coots for 2010 has been determined. The right to the waiver payment for each of Messrs. Winchester and Edwards is conditioned on his employment with Boots & Coots immediately prior to the effective time of the merger.

Each of Messrs. Winchester and Edwards also has agreed, by separate letter agreement, to elect to receive only Halliburton common stock in the merger with respect to each share of Boots & Coots restricted stock held by him as of April 9, 2010 or thereafter acquired. In addition, each of Messrs. Winchester and Edwards has agreed to hold all Halliburton common stock received by him in the merger for a period of one year, except that each of them may sell a number of shares sufficient to provide for the payment of any tax obligations relating to the receipt of Halliburton common stock in the merger.

Estimated Termination Payments Upon a Change of Control of Boots & Coots

The following table shows the potential payments to Boots & Coots’ executive officers under the employment or severance agreements with Boots & Coots described above upon a change in control assuming that the effective time of the change in control is September 1, 2010 and the employee is involuntarily terminated or resigns for a good reason under the applicable agreement on that date. Termination on a different date may result in different amounts being payable to an employee.


	Jerry L. Winchester		DeWitt H. Edwards		Cary Baetz

Cash Severance – Salary(1)	$	1,000,000	$	567,000	$	577,500
Cash Severance – Bonus(2)		1,500,000		680,400		693,000
Benefit Continuation(3)		42,027		23,063		34,176
Stock Options and SARs(4)		47,250		31,500		0
Restricted Stock(5)		2,154,114		1,214,181		1,018,302
Tax Gross-Up(6)		1,456,702		705,198		697,578
Total	$	6,200,093	$	3,221,342	$	3,020,556


(1)		Each of the officers is entitled to a cash severance amount equal to a multiple of his annual base salary. The multiple for Mr. Winchester is 2.5 and the multiple for Messrs. Edwards and Baetz is 2.0. The amounts shown in the table were calculated by applying the applicable multiple to the applicable 2010 base salary.

(2)		Each officer is entitled to a cash severance amount equal to a multiple of the bonus which such officer is eligible to receive for the year in which termination following a change in control occurs. The multiple for Mr. Winchester is 2.5 and the multiple for Messrs. Edwards and Baetz is 2.0. Based upon the financial performance of Boots & Coots, the bonus (as a percentage of base salary) for Messrs. Winchester, Edwards and Baetz may be 0-150%, 0-120%, and 0-120%, respectively. The amounts shown in the table set forth the maximum possible change in control payment to which each officer may be entitled based upon the bonus for which such officer is eligible for 2010.

(3)		The officers are entitled to continued coverage under Boots & Coots’ group health plan for 2.5 years for Mr. Winchester and 2 years for Messrs. Edwards and Baetz. The amounts shown reflect the estimated cost of COBRA continuation coverage for the officer during the applicable period.

(4)		Under the merger agreement, option and SAR awards, whether or not vested, will be converted into an obligation of Halliburton to make a cash payment to the holder equal to the product of (i) the number of shares of Boots & Coots common stock subject to the option or SAR and (ii) the excess, if any, of $3.00 per share, the aggregate consideration per share under the merger agreement, over the exercise price per share of the option or SAR. Amounts shown in the table reflect such cash payments for previously unvested stock options or SARs held by the officers. Amounts that would be payable with respect to previously vested options and SARs are not included in the table.


(5)		Restricted stock awards will automatically vest immediately prior to the effective time of the merger and each holder, except Messrs. Winchester and Edwards, has the right to make the same elections as other Boots & Coots stockholders as described in “Terms of the Merger Agreement — Per Share Merger Consideration” and “— Election Procedures.” As described above, Messrs. Winchester and Edwards have agreed to elect to receive only Halliburton common stock in the merger with respect to each share of Boots & Coots restricted stock owned by them as of April 9, 2010 or thereafter acquired. Accordingly, the payment for restricted share awards has been calculated by multiplying the number of previously unvested shares of restricted stock by $3.00 per share, which is the aggregate consideration per share under the merger agreement. The value of restricted stock for Mr. Baetz does not include the value of 37,500 shares of restricted stock that vested in accordance with their terms on August 1, 2010.


(6)		The tax gross-up value is calculated on the value of the vesting acceleration of the options, SARs and restricted stock determined in accordance with the rules set out in the Treasury Regulations related to Code Section 280G rather than on the amounts calculated using the methods described in footnotes (4) and (5) to this table. The tax gross-up value also includes the value of the cash severance (salary and


		bonus) and the value of the benefit continuation in accordance with the Treasury Regulations related to Code Section 280G. The bonus amount utilized to calculate the tax gross-up value is the maximum bonus amount set forth in the table.

As discussed above, Messrs. Edwards and Winchester have entered into Waiver Agreements with Boots & Coots with respect to the severance benefits payable under their employment agreements with Boots & Coots. As a result, if the merger with Halliburton is consummated, they will receive lump sum cash payments equal to the cash amounts that otherwise would be payable to them under their respective employment agreements in respect of cash severance and benefit continuation regardless of whether they experience a termination of employment, and they will not be entitled to benefits continuation as provided under their employment agreements. See “— Change of Control Arrangements.”

Indemnification and Insurance

The merger agreement provides for indemnification of and the provisions of insurance policies for Boots & Coots’ directors and executive officers following completion of the merger. Under the merger agreement, Gradient must, for a period of six years following the effective time of the merger:


	•	include in its organizational documents indemnification, exculpation and expense-advancement provisions that are no less favorable than those set forth in Boots & Coots’ organizational documents; and

	•	maintain Boots & Coots’ directors’ and officers’ liability insurance policies or substitute therefor policies on terms no less advantageous to such individuals, provided that Gradient will not be required to pay annual premiums in excess of 200% of the current annual premium being paid by Boots & Coots, but in that case Gradient will purchase as much coverage as possible for that amount.

The indemnification rights described above will be in addition to any other rights available under the organizational documents of Boots & Coots or its subsidiaries, any other indemnification agreement or arrangement, Delaware law or otherwise.

Other Benefit Arrangements

Boots & Coots executive officers who remain employed by Halliburton following the merger will be credited for service with Boots & Coots, and prior service for Halliburton if the executive officer was employed by Halliburton immediately prior to employment with Boots & Coots, in each case for purposes of eligibility and vesting purposes, but not benefit accrual (other than vacation, short-term disability and severance pay), under Halliburton’s benefit plans, programs, policies and arrangements. Boots & Coots’ executive officers will be eligible to participate in Halliburton’s welfare plans without any pre-existing condition exclusions.

Appraisal Rights

If appraisal rights are available, a holder of record of shares of Boots & Coots common stock outstanding immediately prior to the effective time of the merger who has not voted in favor of, or consented in writing

to, the adoption of the merger agreement and who has delivered a written demand for appraisal of such shares, executed by or on behalf of the stockholder of record, in accordance with Section 262 of the DGCL will not be converted into the right to receive the merger consideration, unless and until the dissenting holder fails to perfect or effectively withdraws or otherwise loses his, her or its right to appraisal and payment under the DGCL. If, after the effective time of the merger, a dissenting stockholder fails to perfect or otherwise waives, or withdraws or loses his, her or its right to appraisal, or a court determines that such holder is not entitled to relief under the DGCL, then such holder or holders (as the case may be) will forfeit such rights and his, her or its shares of Boots & Coots common stock will be treated as if they had been converted as of the effective time of the merger into the right to receive the merger consideration without interest thereon, upon surrender of the certificate or certificates that formerly evidenced such shares.

The following discussion is not a complete statement of appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262 of the DGCL, which explains the procedures and requirements for exercising statutory appraisal rights and which is attached as Annex C to this proxy statement/prospectus and incorporated herein by reference. All references in Section 262 of the DGCL and in this summary to a “stockholder” are, unless otherwise indicated, to the record holder of the shares of Boots & Coots common stock as to which appraisal rights are asserted. Stockholders intending to exercise appraisal rights should review Annex C carefully. To the extent appraisal rights are available in connection with the merger, this proxy statement/prospectus constitutes notice to Boots & Coots’ stockholders concerning the availability of appraisal rights under Section 262 of the DGCL.

A Boots & Coots stockholder who wishes to exercise appraisal rights should review carefully the following discussion and Annex C to this proxy statement/prospectus because failure to comply timely and fully with the procedures required by Section 262 of the DGCL will result in the loss of any available appraisal rights.

To the extent that appraisal rights are available in connection with the merger under the DGCL, Boots & Coots stockholders who do not wish to accept the merger consideration will be entitled to, subject to compliance with the requirements summarized below, demand an appraisal by the Delaware Court of Chancery of the “fair value” of their shares of Boots & Coots common stock and be paid in cash such amount in lieu of the merger consideration that they would otherwise be entitled to receive if the merger is consummated. For this purpose, the fair value of shares of Boots & Coots common stock will be their fair value, excluding any element of value arising from the consummation or expectation of consummation of the merger, but including, unless the court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment compounded quarterly and accruing at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Stockholders who desire to exercise their appraisal rights must satisfy all of the conditions of Section 262 of the DGCL, including:


	•	Written Demand for Appraisal Prior to the Vote at the Special Meeting. A stockholder must deliver to Boots & Coots a written demand for appraisal meeting the requirements of Section 262 of the DGCL before Boots & Coots stockholders vote on the adoption of the merger agreement at the special meeting. Voting against or abstaining with respect to the adoption of the merger agreement, failing to return a proxy or returning a proxy voting against or abstaining with respect to the proposal to adopt the merger agreement will not constitute the making of a written demand for appraisal. The written demand for appraisal must be separate from any proxy, abstention from the vote on the merger agreement or vote against the merger agreement. The written demand must reasonably inform Boots & Coots of the identity of the stockholder of record and of that stockholder’s intent to demand appraisal of his, her or its shares. Failure to timely deliver a written demand for appraisal will cause a stockholder to lose his, her or its appraisal rights.

	•	Refrain from Voting in Favor of Adoption of the Merger Agreement. In addition to making a written demand for appraisal, a stockholder must not vote his, her or its shares of Boots & Coots common stock in favor of the adoption of the merger agreement. A submitted proxy not marked “AGAINST” or


		“ABSTAIN” will be voted in favor of the proposal to adopt the merger agreement and will result in the waiver of appraisal rights. A stockholder that has not submitted a proxy will not waive his, her or its appraisal rights solely by failing to vote if the stockholder satisfies all other provisions of Section 262 of the DGCL.


	•	Continuous Ownership of Boots & Coots Common Stock. A stockholder must also continuously hold his, her or its shares of Boots & Coots common stock from the date the stockholder makes the written demand for appraisal through the effective time of the merger. Accordingly, a stockholder who is the record holder of shares of Boots & Coots common stock on the date the written demand for appraisal is made but who thereafter transfers the shares prior to the effective time of the merger will lose any right to appraisal with respect to such shares.

	•	Petition with the Chancery Court. Within 120 days after the effective date of the merger (but not thereafter), either the surviving corporation or any stockholder who has complied with the requirements of Section 262 of the DGCL, which are briefly summarized above, must file a petition in the Delaware Court of Chancery demanding a judicial determination of the fair value of the shares of Boots & Coots common stock held by all stockholders who are entitled to appraisal rights. This petition in effect initiates a court proceeding in Delaware. Because Gradient, as the surviving corporation, has no obligation and no intention to file such a petition, if no stockholder files such a petition with the Delaware Court of Chancery within 120 days after the effective date of the merger, any available appraisal rights will be lost, even if a stockholder has fulfilled all other requirements to exercise appraisal rights. If such a petition is filed, the Delaware Court of Chancery could determine that the fair value of shares of Boots & Coots common stock is more than, the same as or less than the merger consideration. Notwithstanding that a demand for appraisal must be executed by or on behalf of a stockholder of record, a beneficial owner of shares entitled to appraisal rights held either in a voting trust or by a nominee on behalf of that beneficial owner may, in that beneficial owner’s own name, file a petition for appraisal with respect to the shares beneficially owned by that person and as to which appraisal rights have been properly perfected.

Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to adopt the merger agreement will constitute a written demand for appraisal within the meaning of Section 262 of the DGCL. The written demand for appraisal must be in addition to and separate from any proxy or vote.

A demand for appraisal must be executed by or on behalf of the stockholder of record, fully and correctly, as such stockholder’s name appears on the stock certificate and must state that such person intends to demand appraisal of his, her or its shares of Boots & Coots common stock. If the shares are owned of record by a person other than the beneficial owner, including a broker, fiduciary (such as a trustee, guardian or custodian), depositary or other nominee, this demand must be executed by or for the record owner. If the shares are owned by or for more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record. However, the agent must identify the record owner and expressly disclose that, in exercising the demand, he is acting as agent for the record owner. A person having a beneficial interest in Boots & Coots common stock held of record in the name of another person, such as a broker or nominee, must act promptly to cause the record holder to follow the steps summarized herein in a timely manner to perfect whatever appraisal rights the beneficial owner may have.

A stockholder who elects to exercise appraisal rights should mail or deliver his, her or its written demand to Boots & Coots’ principal executive offices at 7908 North Sam Houston Parkway W., 5th Floor, Houston, Texas 77064, Attention: General Counsel. The written demand for appraisal should state the stockholder’s name, mailing address and the number of shares of Boots & Coots common stock owned by the stockholder, and must reasonably inform Boots & Coots that the stockholder intends thereby to demand appraisal of his, her or its shares of Boots & Coots common stock. If appraisal rights are available in connection with the merger, within ten days after the effective date of the merger, Gradient will provide notice of the effective date

of the merger to all Boots & Coots stockholders who have complied with Section 262 of the DGCL and have not voted for the merger. A record holder, such as a broker, fiduciary, depositary or other nominee, who holds shares of Boots & Coots common stock as a nominee for others, may exercise any available appraisal rights with respect to the shares held for all or less than all beneficial owners of shares as to which that person is the record owner. In that case, the written demand must set forth the number of shares covered by the demand. When the number of shares is not expressly stated, the demand will be presumed to cover all shares of Boots & Coots common stock outstanding in the name of that record owner.

Within 120 days after the effective date of the merger (but not thereafter), any stockholder (including any beneficial owner of shares entitled to appraisal rights) who is entitled to appraisal rights in connection with the merger and has satisfied the requirements of Section 262 of the DGCL may deliver to Gradient a written demand for a statement listing the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of those shares. Gradient, as the surviving corporation in the merger, must mail that written statement to the stockholder within ten days after the stockholder’s request is received by Gradient or within ten days after the latest date for delivery of a demand for appraisal under Section 262 of the DGCL, whichever is later. If a petition for appraisal rights is timely filed in the Court of Chancery of the State of Delaware as set forth above and a copy is served on Gradient, as the surviving corporation, Gradient must then, within 20 days after service, file in the office of the Delaware Register in Chancery, a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached with Gradient. If Gradient files a petition, the petition must be accompanied by the duly verified list. The Register in Chancery, if so ordered by the court, will give notice of the time and place fixed for the hearing of that petition by registered or certified mail to Gradient and to the stockholders shown on the list at the addresses therein stated, and notice also will be given by publishing a notice at least one week before the day of the hearing in a newspaper of general circulation published in the City of Wilmington, Delaware, or such publication as the court deems advisable. The court must approve the forms of the notices by mail and by publication, and Gradient must bear the costs of the notices.

At the hearing on the petition, the Court of Chancery of the State of Delaware will determine which stockholders have become entitled to appraisal rights. The court may require the stockholders who have demanded an appraisal for their shares (and who hold stock represented by certificates) to submit their stock certificates to the Register in Chancery for notation of the pendency of the appraisal proceedings and the Court of Chancery of the State of Delaware may dismiss the proceedings as to any stockholder that fails to comply with that direction.

After determining which stockholders are entitled to appraisal rights, the court will appraise the shares owned by those stockholders, determining the “fair value” of those shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest to be paid, if any, upon the amount determined to be the fair value. In determining the fair value, the court must take into account all relevant factors. The Delaware Supreme Court has stated that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” Elements of future value, including the nature of the enterprise that are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered, but any element of value arising from accomplishment or expectation of the merger may not be considered. Boots & Coots stockholders considering seeking appraisal of their shares should note that the fair value of their shares determined under Section 262 of the DGCL could be more than, the same as or less than the consideration they would receive pursuant to the merger agreement if they did not seek appraisal of their shares.

The costs of the appraisal proceeding may be determined by the court and taxed against the parties as the court deems equitable under the circumstances. However, costs do not include attorney’s and expert witness fees. Each dissenting stockholder is responsible for his, her or its attorney’s and expert witness fees, although, upon application of a stockholder who has perfected appraisal rights, the court may order that all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without

limitation, reasonable attorney’s fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal.

If a stockholder demands appraisal rights in compliance with the requirements of Section 262 of the DGCL, then, after the effective time of the merger, that stockholder will not be entitled to: (i) vote that stockholder’s shares of Boots & Coots common stock for any purpose; (ii) receive payment of dividends or other distributions on that stockholder’s shares that are payable to stockholders of record at a date after the effective time of the merger; or (iii) receive payment of any consideration provided for in the merger agreement. A stockholder may withdraw his, her or its demand for appraisal rights by a writing withdrawing his, her or its demand for appraisal and accepting the merger consideration at any time within 60 days after the effective time of the merger, or at any time thereafter with Gradient’s written approval. Notwithstanding the foregoing, no appraisal proceeding in the Delaware Court of Chancery may be dismissed as to any stockholder without the approval of the court and that approval may be conditioned upon such terms as the court deems just, but this rule does not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw that stockholder’s demand for appraisal and to accept the terms offered in the merger agreement within 60 days after the effective date of the merger. Subject to the foregoing and Halliburton’s right to require that any dissenting shares be treated as cash election shares not subject to proration, if any Boots & Coots stockholder withdraws his, her or its demand for appraisal rights, then his, her or its shares of Boots & Coots common stock will be automatically converted into the right to receive the mixed cash and stock consideration, without interest.

Any stockholder wishing to exercise appraisal rights is urged to consult legal counsel before attempting to do so. Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL may result in the loss of any available appraisal rights.

Regulatory Requirements

The merger is subject to antitrust laws. Halliburton and Boots & Coots have made their respective filings under applicable U.S. antitrust laws with the Antitrust Division and the FTC. Early termination of the waiting period was granted on April 29, 2010.

At any time before or after the completion of the merger, the Antitrust Division, the FTC or any state could take any action under the antitrust laws that any of them considers necessary or desirable in the public interest, including seeking to enjoin the completion of the merger, unwinding the merger or seeking divestitures of particular assets of Halliburton and Boots & Coots. Private parties and non-U.S. governmental authorities may also seek to take legal action under antitrust laws. If a challenge to the merger on antitrust grounds were to be made, Halliburton and Boots & Coots may not prevail.

Litigation Related to the Merger

Subsequent to the announcement of the merger, eight shareholder lawsuits styled as class actions were commenced on behalf of Boots & Coots stockholders against Boots & Coots and members of its board of directors, and in certain cases against Halliburton and Gradient, challenging the merger. The lawsuits have been consolidated as In re Boots & Coots, Inc., Cause No. 2010-24117, in the 133rd Judicial District of Harris County, Texas, and interim class counsel have been appointed. On June 11, 2010, a consolidated amended petition was filed, alleging that Boots & Coots’ directors breached their fiduciary duties by, among other things, causing Boots & Coots to enter into the merger agreement at an allegedly unfair price and agreeing to merger agreement terms that improperly inhibit alternative transactions. The lawsuit further alleges that the Form S-4 Registration Statement filed on May 7, 2010, is materially misleading and omits material facts. The lawsuit also alleges that Boots & Coots, Halliburton and Gradient aided and abetted the directors’ breach of fiduciary duties. The lawsuit seeks, among other things, an injunction barring defendants from consummating the proposed merger and an award of attorneys’ fees.

On May 25, 2010, an additional shareholder lawsuit styled as a class action on behalf of Boots & Coots stockholders against Boots & Coots, members of its board of directors, Halliburton and Gradient, was filed in the United States District Court for the Southern District of Texas, styled Brody v. Winchester et al.,

Case No. 4:10-cv-01882. The action alleged that Boots & Coots’ directors breached their fiduciary duties by, among other things, causing Boots & Coots to enter into the merger agreement at an allegedly unfair price, agreeing to merger agreement terms that improperly inhibit alternative transactions and failing to disclose to shareholders all information material to the proposed merger. The action further alleged that the Form S-4 Registration Statement filed on May 7, 2010, is materially misleading and omits material facts. The complaint alleged that Halliburton and Gradient aided and abetted the Boots & Coots directors’ breaches of fiduciary duties. On June 22, 2010, the plaintiff filed a notice of dismissal. On June 23, 2010, the court dismissed the action without prejudice.

In addition, a Boots & Coots stockholder filed a derivative lawsuit in the Court of Chancery of the State of Delaware on behalf of Boots & Coots and similarly situated stockholders against members of Boots & Coots’ board of directors and, as a nominal defendant, Boots & Coots, styled Silverberg v. Swanson et al., Case No. 5441. The plaintiff alleges that Boots & Coots’ directors breached their fiduciary duties by agreeing to a March 1, 2010 award of restricted stock. The complaint seeks, among other things, disgorgement of the March 1, 2010 restricted stock awarded to members of the Boots & Coots board of directors, monetary damages and attorneys fees.

Boots & Coots and Halliburton believe that the lawsuits described above are without merit and intend to defend these lawsuits vigorously.

TERMS OF THE MERGER AGREEMENT

The following summary describes the material provisions of the merger agreement. The provisions of the merger agreement are complicated and not easily summarized. This summary may not contain all of the information about the merger agreement that is important to you. This summary is qualified in its entirety by reference to the merger agreement attached as Annex A to, and incorporated by reference into, this proxy statement/prospectus. We encourage you to read it carefully in its entirety for a more complete understanding of the merger agreement.

The merger agreement and the following summary have been included to provide you with information regarding the terms of the merger agreement and the transactions described in this proxy statement/prospectus. Neither Halliburton nor Boots & Coots intends that the merger agreement or any of its terms will constitute a source of business or operational information about Halliburton or Boots & Coots. The representations, warranties and covenants contained in the merger agreement were made by Halliburton, Boots & Coots and Gradient only for the purposes of the merger agreement and were qualified and subject to certain limitations and exceptions agreed to by Halliburton, Boots & Coots and Gradient in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were made solely for the benefit of the parties to the merger agreement and were negotiated for the purpose of allocating contractual risk among the parties to the merger agreement rather than to establish matters as facts. The representations and warranties may also be subject to a contractual standard of materiality or material adverse effect different from those generally applicable to shareholders and reports and documents filed with the SEC and in some cases may be qualified by disclosures made by one party to the other, which are not necessarily reflected in the merger agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement, and subsequent developments or new information qualifying a representation or warranty may have been included in or incorporated by reference into this proxy statement/prospectus. Halliburton and Boots & Coots will provide additional disclosure in their public reports of any material information necessary to provide Boots & Coots’ stockholders with a materially complete understanding of the disclosures relating to the merger agreement. Other than as disclosed in this proxy statement/prospectus and the documents incorporated herein by reference, as of the date of this proxy statement/prospectus, neither Halliburton nor Boots & Coots is aware of any material facts that are required to be disclosed under the federal securities laws that would contradict the representations, warranties, or covenants in the merger agreement.

For the foregoing reasons, the representations, warranties and covenants or any descriptions of those provisions should not be read alone or relied upon as characterizations of the actual state of facts or condition of Halliburton, Gradient, Boots & Coots or any of their respective subsidiaries or affiliates. Instead, such provisions or descriptions should be read only in conjunction with the other information provided elsewhere in, or incorporated by reference into, this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 103.

Merger

The merger agreement provides for a transaction in which Boots & Coots will be merged with and into Gradient, with Gradient surviving as a direct wholly owned subsidiary of Halliburton. Upon effectiveness of the merger, each Boots & Coots stockholder will have the right to receive the merger consideration as described below under “— Per Share Merger Consideration.”

Effective Time; Closing

The merger will become effective on the later of (1) the date a certificate of merger is filed with the Delaware Secretary of State and (2) such time, if any, as the parties shall agree as specified in the certificate of merger. The merger agreement provides that the certificate of merger is to be filed no later than the second business day after all the conditions to the closing of the merger are satisfied or waived (other than those

conditions that by their nature are to be fulfilled at the closing, but subject to the fulfillment or waiver of those conditions at the closing). See “— Conditions to the Merger.” Halliburton and Boots & Coots currently expect to consummate the merger promptly upon approval of the Boots & Coots stockholders.

Per Share Merger Consideration

The merger agreement provides that at the effective time of the merger, each share of Boots & Coots common stock issued and outstanding immediately prior to the effective time will be converted into the right to receive either a fraction of a share of Halliburton common stock, an amount of cash or both, in each case as described below. Under the merger agreement, Boots & Coots stockholders may elect to receive consideration consisting of cash, shares of Halliburton common stock, or a combination of both in exchange for their shares of Boots & Coots common stock, subject to the proration feature described in “— Allocation of Merger Consideration.” Boots & Coots stockholders making a valid election to receive a mix of cash and stock consideration will, subject to modification in order to achieve the intended tax consequences of the merger as described below, receive (1) $1.73 in cash and (2) a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $1.27 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. Subject to proration, (i) Boots & Coots stockholders electing to receive all cash will receive $3.00 for each share of Boots & Coots common stock they own and (ii) Boots & Coots stockholders electing to receive only Halliburton common stock will receive a fraction of a share of Halliburton common stock equal to an exchange ratio, which will be calculated by dividing $3.00 by the Halliburton five-day average price, for each share of Boots & Coots common stock they own. A Boots & Coots stockholder failing to make an election will receive consideration as if such stockholder had elected to receive a mix of cash and stock consideration. Based on the number of shares of Boots & Coots common stock outstanding as of July 27, 2010, Halliburton would issue approximately 3.5 million shares of Halliburton common stock and would pay approximately $143.2 million in cash in connection with the merger, excluding an estimated $4.9 million in cash payments to holders of Boots & Coots stock options and SARs. At the effective time of the merger, each share of Boots & Coots common stock issued and held in Boots & Coots’ treasury or held by Halliburton or Gradient or any of their subsidiaries will be canceled without payment of any consideration.

Under the merger agreement, if and to the minimum extent necessary for Baker Botts L.L.P. and Thompson & Knight LLP to deliver their opinions to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the allocation of the total merger consideration to be paid in cash and Halliburton common stock will change. See “The Merger — Opinions as to Material U.S. Federal Income Tax Consequences of the Merger.” The value of $1.27, which is used to compute the exchange ratio for the stock portion of the total merger consideration, will be increased, and the $1.73 in cash to be paid per share of Boots & Coots common stock, will be correspondingly decreased, to the minimum extent necessary for the aggregate fair market value of all shares of Halliburton common stock that would be issued pursuant to the merger (valued as of the effective date of the merger), referred to as the “total stock value,” to constitute not less than 40% of the sum of the total stock consideration plus the total amount of cash paid to Boots & Coots stockholders pursuant to the merger, which sum is referred to as the “total merger value,” considering the following factors:


	•	for tax purposes, tax counsel will treat shares of Boots & Coots restricted stock that are exchanged for Halliburton common stock in the merger as having been exchanged for cash solely for purposes of computing the total stock value; and

	•	the fair market value of a share of Halliburton common stock is determined for tax purposes as of the effective date of the merger instead of using the Halliburton five-day average price.

See “Material U.S. Federal Income Tax Consequences of the Merger — Qualification of the Merger as a Reorganization and Tax Opinions.” The minimum number of shares of Boots & Coots restricted stock that would need to be exchanged for Halliburton common stock in order to cause a reallocation of merger consideration will vary depending on the fair market value of a share of Halliburton common stock as of the effective date of the merger and the Halliburton five-day average price. For example, if the fair market value

of a share of Halliburton common stock valued as of the effective date of the merger is equal to the Halliburton five-day average price, then a reallocation of the merger consideration would occur if more than approximately 60.9% of the shares of Boots & Coots restricted stock are exchanged solely for Halliburton common stock in the merger, but if the fair market value of a share of Halliburton common stock valued as of the effective date of the merger is less than the Halliburton five-day average price, then the reallocation of the merger consideration may occur even if fewer than approximately 60.9% of the shares of Boots & Coots restricted stock are exchanged solely for Halliburton common stock in the merger. As a result of elections to be made by Messrs. Winchester and Edwards to receive only Halliburton common stock in the merger (see “Interests of Certain Persons in the Merger that May be Different from Your Interests — Change of Control Arrangements”), as of July 27, 2010, 1,122,764 shares, or approximately 35.4% of all outstanding shares, of Boots & Coots restricted stock may be exchanged for Halliburton common stock but be treated as having been exchanged for cash solely for purposes of computing the total stock value. See “Material U.S. Federal Income Tax Consequences of the Merger — Qualification of the Merger as a Reorganization and Tax Opinions.” The reallocation of the merger consideration will, to the minimum extent necessary, have the effect of reducing the amount of cash paid to Boots & Coots stockholders, and correspondingly increasing the number of shares of Halliburton common stock issued to Boots & Coots stockholders.

We refer to the number of shares of Halliburton common stock to be received for each share of Boots & Coots common stock as the “stock consideration,” the amount of cash to be received for each share of Boots & Coots common stock as the “cash consideration” and the stock consideration together with the cash consideration as the “merger consideration.”

Adjustment of the Merger Consideration

The merger consideration will be adjusted appropriately to reflect the effect of any recapitalization, split-up, stock split, subdivision, combination or exchange of shares or any dividend payable in stock or other securities declared on or rights issued with respect to Halliburton common stock or Boots & Coots common stock having a record date after the date of the merger agreement but at or before the effective time of the merger.

Fractional Shares

No fractional shares of Halliburton common stock will be issued in connection with the merger. Instead, each Boots & Coots stockholder otherwise entitled to a fraction of a share of Halliburton common stock (after aggregating all fractional shares of Halliburton common stock issuable to that stockholder) will be entitled to receive an amount in cash (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the Halliburton five-day average price.

Allocation of Merger Consideration

Subject to modification in order to achieve the intended tax consequences of the merger, the aggregate cash consideration to be received by Boots & Coots stockholders pursuant to the merger will be fixed at an amount equal to the product of $1.73 and the number of issued and outstanding shares of Boots & Coots common stock immediately prior to closing of the merger (excluding certain shares that do not convert into the right to receive merger consideration). Accordingly, if Boots & Coots stockholders elect, in the aggregate, to receive cash in an amount greater than the aggregate cash consideration payable under the merger agreement, or less than the aggregate cash consideration payable under the merger agreement, then those holders electing to receive either all cash or all stock consideration, as the case may be, will be pro rated down and will receive the undersubscribed form of merger consideration as a portion of the overall consideration they receive for their shares. As a result, Boots & Coots stockholders that make a valid election to receive all cash or all stock consideration may not receive merger consideration entirely in the form elected.

Stock Options, SARs and Restricted Shares

At the effective time of the merger, each outstanding option to purchase shares of Boots & Coots common stock and each SAR will fully vest and will be converted into an obligation of Gradient to pay the holder thereof an amount in cash equal to the product of (1) the number of shares of Boots & Coots common stock subject to the option or SAR, as applicable, and (2) the excess, if any, of $3.00 over the exercise price per share previously subject to such option or SAR.

Immediately prior to the effective time of the merger, each outstanding award of restricted stock granted by Boots & Coots pursuant to an employee benefit plan will become fully vested, and each holder has the right to make the same elections as described above in “— Per Share Merger Consideration.”

Dissenting Shares

In certain circumstances, holders of Boots & Coots stock who have not voted in favor of or consented to the merger and have otherwise complied with the provisions of Section 262 of the DGCL as to appraisal rights will be entitled to such rights as are granted by Section 262 of the DGCL. If any holder of such dissenting shares fails to perfect, withdraws or loses the right to appraisal under Section 262 of the DGCL, then each dissenting share held by that holder will be deemed to have been converted into the right to receive the mixed cash and stock consideration, without interest. See “The Merger — Appraisal Rights.”

At the election deadline described under “— Election Procedures” below, Halliburton will have the right to require, but not the obligation to require (unless necessary to maintain the merger’s tax status as a reorganization under Section 368(a) of the Internal Revenue Code), that any shares of Boots & Coots common stock that constitute dissenting shares at the election deadline be treated as shares electing to receive the cash consideration not subject to proration. Also, if Halliburton requires, any dissenting shares that may otherwise convert into the right to receive the merger consideration shall be treated as cash election shares not subject to the pro rata selection process. For a description of the allocation of merger consideration between cash and stock, see “— Allocation of Merger Consideration.”

Boots & Coots is required to give Halliburton prompt notice of any written demand for appraisal of Boots & Coots common stock and to afford Halliburton the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL.

Election Procedures

The election form and other appropriate and customary transmittal materials will be mailed to Boots & Coots stockholders on or about , 2010, a date which is at least 30 days prior to the anticipated effective time of the merger.

The election form will permit each Boots & Coots stockholder to specify the number of Boots & Coots shares with respect to which that holder elects to receive the (1) mixed cash and stock consideration, (2) all stock consideration or (3) all cash consideration. The election must be made prior to the election deadline. Unless extended or otherwise agreed upon by Halliburton and Boots & Coots, the election deadline will be 5:00 p.m., New York time, on the 20th day following the date the election form is mailed to Boots & Coots stockholders.

To make a valid election, each Boots & Coots stockholder must submit a properly completed election form so that it is received by the exchange agent at or prior to the election deadline. An election form will be properly completed only if accompanied by one or more certificates that represent the stockholder’s shares of Boots & Coots common stock covered by the election form (or customary affidavits and, if required, the posting of a bond as indemnity against any claim that may be made with respect to such certificate) and/or, in case of book-entry shares, upon the receipt of an “agent’s message” by the exchange agent or such other evidence of transfer as the exchange agent may reasonably request together with any additional documents specified by the procedures set forth in the election form.

If a Boots & Coots stockholder does not make an election to receive all cash consideration or all stock consideration pursuant to the merger, the election form is not received by the exchange agent by the election deadline or the election form is improperly completed and/or is not signed, the stockholder will be considered not to have made a valid election. We sometimes refer to such stockholders’ shares as “non-election shares.” Stockholders not making an election will receive the mixed cash and stock consideration.

The actual allocation of cash and stock will be subject in each case to the allocation procedures set forth in the merger agreement. Under those procedures, a Boots & Coots stockholder who makes an all cash election will not receive all cash if the cash election pool is oversubscribed, and a Boots & Coots stockholder who makes an all stock election will not receive all stock if the stock election pool is oversubscribed. For more information regarding these allocation procedures, see “— Allocation of Merger Consideration.”

Any election form may be revoked or changed by written notice received by the exchange agent prior to the election deadline. If the election is validly revoked, the shares of Boots & Coots common stock covered by that election form will become non-election shares unless the stockholder properly makes a subsequent election. Halliburton will have sole discretion, which it may delegate in whole or in part to the exchange agent, to determine, in good faith, whether any election, revocation or change has been made properly or timely and to disregard immaterial defects in the election forms. None of Halliburton, Gradient or the exchange agent will be under any obligation to notify stockholders of any defect in an election form.

Surrender of Shares; Stock Transfer Books

Prior to the effective time of the merger, Halliburton will deposit with BNY Mellon Shareowner Services, as the exchange agent for the merger, the number of shares of Halliburton common stock to be issued and cash to be paid to Boots & Coots stockholders equal to the cash portion of the merger consideration, in each case pursuant to the merger agreement. That cash will be invested by the exchange agent as directed by Halliburton, provided that no investment or losses thereon shall affect the amount of the merger consideration payable under the merger agreement.

Promptly after the effective time of the merger, Halliburton will cause the exchange agent to send to each holder of record of Boots & Coots common stock at the effective time of the merger a letter of transmittal and instructions for effecting the exchange of Boots & Coots common stock for the merger consideration the holder is entitled to receive under the merger agreement. Upon surrender of the certificates or book-entry shares for cancellation (if not previously submitted with an election form), along with the executed letter of transmittal and other documents, a Boots & Coots stockholder will receive, without interest and as applicable: (i) the stock consideration; (ii) the cash consideration; (iii) cash in lieu of fractional shares of Halliburton common stock; and (iv) any unpaid dividends and distributions in respect of Halliburton common stock with a record date after the effective time of the merger.

Delivery of shares of Halliburton common stock to be received in the merger will be in book-entry form.

At any time following 180 days after the effective time of the merger, Halliburton will have the right to require the exchange agent to return any shares of Halliburton common stock and cash that remain unclaimed. Any holder of Boots & Coots common stock that has not exchanged certificates representing that stock prior to that time may thereafter look only to Halliburton to exchange stock certificates or to pay amounts to which that stockholder is entitled pursuant to the merger agreement. None of Halliburton, Boots & Coots or the exchange agent will be liable to any holder of Boots & Coots common stock certificates for any merger consideration delivered to a public official pursuant to escheat or other applicable laws.

Withholding Taxes

Halliburton and the exchange agent will be entitled to deduct and withhold from consideration payable to any Boots & Coots stockholder the amounts that may be required to be withheld under any tax law. The properly withheld amounts will be treated for all purposes of the merger as having been paid to the stockholders from whom they were withheld.

Representations and Warranties

The merger agreement contains representations and warranties made by each of the parties regarding aspects of its business, financial condition and structure and other facts pertinent to the merger.

Definition of “Material Adverse Effect”

Certain representations and warranties of Halliburton and Boots & Coots are qualified as to “material adverse effect.” In addition, there are separate standalone conditions to completion of the merger relating to the absence of any change, effect, event, occurrence, state of facts or development or developments from the date of the merger agreement to the effective time of the merger which has had a material adverse effect on the other party and is continuing.

For purposes of the merger agreement, “material adverse effect” means, with respect to Halliburton or Boots & Coots, as the case may be, a material adverse change to the business, properties, assets, liabilities (contingent or otherwise), financial condition or results of operations of such party and its subsidiaries, taken as a whole, or to the ability of such party to consummate the transactions contemplated by the merger agreement, in each case excluding:


	•	economic, capital market, regulatory or political conditions, any outbreak of hostilities or war (including acts of terrorism) or natural disasters, in each case affecting the applicable industries in which such party participates generally, except, in such case to the extent any such changes or effects materially disproportionately affect such party;

	•	changes resulting from the announcement or pendency of the merger agreement, any actions taken in compliance with merger agreement or the consummation of the merger;

	•	the downgrade in rating of any debt securities of such party by Standard & Poor’s Rating Group, Moody’s Investor Services, Inc. or Fitch Ratings;

	•	changes in the price or trading volume of such party’s stock;

	•	changes in applicable law or U.S., foreign or international generally accepted accounting principles or financial reporting standards or interpretations thereof; and

	•	any failure to meet analyst projections, in and of itself.

For purposes of analyzing whether a material adverse effect has occurred, the analysis of materiality is not limited to a long-term perspective.

Conduct of Business Pending the Effective Time

Except as set forth in the disclosure schedules provided by Boots & Coots, as expressly permitted by the merger agreement, as required by applicable law or as consented to in writing by Halliburton, Boots & Coots has agreed that, prior to the effective time of the merger it and its subsidiaries will:

	•	enter into an agreement, contract, commitment or arrangement to do any of the prohibited actions described in the bullet points above.

Certain Additional Agreements

Stockholder Meeting. Unless the merger agreement is earlier terminated, the board of directors of Boots & Coots must submit the merger agreement for adoption by its stockholders at the stockholder meeting, even if the board of directors changes its recommendation with regard to the merger agreement.

No Solicitation, Recommendation. Boots & Coots and its subsidiaries will not, and Boots & Coots and its subsidiaries will cause their respective officers, directors, investment bankers, attorneys, accountants, financial advisors, agents and other representatives (collectively, the “Representatives”) not to:


	•	directly or indirectly, initiate, solicit or encourage or take any action to facilitate (including by way of furnishing nonpublic information) any inquiry regarding or the making or submission of any proposal that constitutes, or could reasonably be expected to lead to, an acquisition proposal (as defined below);

	•	directly or indirectly, participate or engage in discussions or negotiations with or disclose any information relating to Boots & Coots or any of its subsidiaries, or afford access to the properties, books or records of Boots & Coots or any of its subsidiaries to, or otherwise cooperate in any way with, any person that has made an acquisition proposal or that Boots & Coots or any of its subsidiaries or any of their Representatives knows or has reason to believe is contemplating making an acquisition proposal; or

	•	accept an acquisition proposal or enter into any agreement, arrangement or understanding, including any letter of intent or agreement in principle (other than a permitted confidentiality agreement), (1) providing for, constituting or relating to an acquisition proposal or (2) that would require, or could have the effect of causing, Boots & Coots to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement.

The term “acquisition proposal,” means any proposal, whether or not in writing, for the


	•	direct or indirect acquisition or purchase of a business or assets that generates or constitutes 15% or more of the net revenues, net income or the assets of Boots & Coots and its subsidiaries, taken as a whole,

	•	direct or indirect acquisition or purchase of 15% or more of any equity securities or capital stock of Boots & Coots or any equity securities or capital stock of its subsidiaries that, individually or in the aggregate, represent a direct or indirect ownership interest in 15% or more of Boots & Coots’ consolidated assets, or


	•	merger, consolidation, restructuring, transfer of assets or other business combination, sale of shares of capital stock, tender offer, exchange offer, recapitalization, stock repurchase program or other similar transaction that if consummated would result in any person or persons beneficially owning 15% or more of any equity securities or capital stock of Boots & Coots or any equity securities or capital stock of its subsidiaries that, individually or in the aggregate, represent a direct or indirect ownership interest in 15% or more of Boots & Coots’ consolidated assets,

in each case other than the transactions contemplated by the merger agreement.

However, prior to the time Boots & Coots’ stockholders adopt the merger agreement, Boots & Coots or its board of directors may participate and engage in discussions and negotiations with and disclose any information relating to Boots & Coots and its subsidiaries, afford access to the properties, books or records of Boots & Coots and its subsidiaries to, and otherwise cooperate in any way with, any person that has made an acquisition proposal if:


	•	Boots & Coots receives a bona fide written acquisition proposal from such person (and such acquisition proposal was not initiated, solicited, encouraged or facilitated by Boots & Coots or any of its subsidiaries or any of their respective Representatives in violation of the merger agreement and did not otherwise result from a violation of the merger agreement or any standstill agreement);

	•	Boots & Coots’ board of directors determines in good faith by resolution duly adopted (after consultation with financial advisors and outside legal counsel of nationally recognized reputation) that:


	•	such proposal constitutes or is reasonably likely to result in a superior proposal (as defined below) from the person that made the applicable acquisition proposal; and

	•	the person making such acquisition proposal has the financial and legal capability and capacity to consummate such acquisition proposal;


	•	Boots & Coots’ board of directors determines after the receipt of advice from outside legal counsel that the failure to take such action would be reasonably likely to result in a breach of its fiduciary duties under applicable law;

	•	Boots & Coots, before providing any information to such person, receives from such person an executed confidentiality agreement having terms that are no less favorable to Boots & Coots than Boots & Coots’ confidentiality agreement with Halliburton Energy (referred to as a permitted confidentiality agreement); and

	•	Boots & Coots previously provided or made available or promptly provides or makes available to Halliburton any material non-public information concerning Boots & Coots or its subsidiaries that is provided to the person making such acquisition proposal.

Boots & Coots shall promptly (and in any event within 48 hours) notify Halliburton orally and in writing of the identity of any person making, and provide to Halliburton a copy of, any acquisition proposal, inquiry or request (or, where no such copy is available, a written description of such acquisition proposal, inquiry or request), including any material modifications thereto. Boots & Coots shall keep Halliburton reasonably informed on a prompt basis (and in any event within 48 hours) of the status and details of any acquisition proposal, indication, inquiry or request (including the material terms and conditions thereof and of any modifications thereto). Also, Boots & Coots shall promptly (and in any event within 24 hours) notify Halliburton orally and in writing if it determines to engage in any actions described in the immediately preceding paragraph and shall keep Halliburton reasonably informed on a prompt basis (and in any event within 24 hours) of the status and details of any such actions.

In addition to the restrictions described above and subject to the exceptions described below, (1) Boots & Coots’ board of directors may not change the Boots & Coots board of directors’ recommendation of the merger (as defined below) and (2) none of Boots & Coots or any of its subsidiaries may execute or enter into, any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other

similar agreement, arrangement or understanding, constituting or related to, or that is intended to or could reasonably be expected to lead to, any acquisition proposal (other than a permitted confidentiality agreement) or requiring it to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement.

However, prior to the time Boots & Coots’ stockholders adopt the merger agreement and subject to Boots & Coots’ compliance with certain provisions of the merger agreement relating to the stockholder meeting and no solicitation, Boots & Coots’ board of directors may, in response to a superior proposal (as defined below), change the Boots & Coots board of directors’ recommendation (as defined below), if Boots & Coots’ board of directors:


	•	determines in good faith, after consultation with outside legal counsel, that the failure to take such action would be reasonably likely to result in a breach of its fiduciary duties to the Boots & Coots stockholders; and

	•	provides prior written notice to Halliburton that it is contemplating taking such action and specifying the material facts and information constituting the basis for such action, including the terms and conditions of such superior proposal, five business days have passed since receipt by Halliburton of such notice, and during such five business day period, at the request of Halliburton, Boots & Coots has negotiated in good faith with respect to any changes or modifications to the merger agreement which would allow the Boots & Coots board of directors not to take such action consistent with its fiduciary duties (any changes to the financial terms or any other material term of such superior proposal shall require a new notice and a new five business day period).

Notwithstanding the foregoing, Boots & Coots and its board of directors may take and disclose to Boots & Coots’ stockholders a position with respect to an acquisition proposal pursuant to Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act or make any similar disclosure, in either case to the extent required by applicable law. However, compliance with those rules will not limit or modify the effect that any such action pursuant to those rules has under the merger agreement.

The term “superior proposal” means any bona fide written acquisition proposal that was not initiated, solicited encouraged or facilitated by Boots & Coots or any of its subsidiaries or any of its Representatives in violation of the merger agreement, made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, share exchange, asset purchase or other business combination,


	•	all or substantially all of the assets of Boots & Coots and its subsidiaries, taken as a whole, or

	•	100% of the equity securities of Boots & Coots,

in each case on terms that Boots & Coots’ board of directors determines (after consultation with financial advisors and outside legal counsel of nationally recognized reputation) in good faith by resolutions duly adopted:


	•	would result in a transaction that, if consummated, is more favorable to the Boots & Coots stockholders than the merger, taking into account all the terms and conditions of such proposal, the person making such proposal and the merger agreement (including any break-up fees, expense reimbursement provisions, conditions to consummation and any changes to the terms of the merger agreement offered by Halliburton in response to such superior proposal or otherwise pursuant to the merger agreement); and

	•	is reasonably likely to be completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal.

Notwithstanding the foregoing, no proposal will be deemed to be a superior proposal if it is subject to a financing condition or any financing required to consummate the proposal is not committed (unless it is reasonable to conclude that the proposed acquiror has adequate financial resources to consummate the transaction).

The term “change in the Boots & Coots board of directors’ recommendation” means Boots & Coots’ board of directors or any committee thereof, directly or indirectly:


	•	withdrawing (or amending, qualifying or modifying in a manner adverse to Halliburton or Gradient), or proposing to withdraw (or amend, qualify or modify in a manner adverse to Halliburton or Gradient), the approval, recommendation or declaration of advisability of the merger agreement, the merger or the other transactions contemplated by the merger agreement; or

	•	recommending, adopting or approving, or proposing publicly to recommend, adopt or approve, any acquisition proposal.

Boots & Coots has also agreed not to, other than with respect to Halliburton and Gradient, (1) waive, modify, terminate, or fail to enforce any “standstill” obligation of any person, (2) modify, waive, amend or terminate its rights agreement, or (3) render the restrictions on “business combinations” (as defined in Section 203 of the DGCL) under Section 203 of the DGCL inapplicable to any person. Boots & Coots has also agreed to terminate any existing activities, discussions or negotiations with any person conducted prior to the date of the merger agreement with respect to any possible acquisition proposal.

Employee Matters. Boots & Coots employees who remain employed by Halliburton following the merger will be credited for service with Boots & Coots for purposes of eligibility and vesting purposes, but not benefit accrual (other than vacation, short-term disability and severance pay), under Halliburton’s benefit plans, programs, policies and arrangements. Halliburton will continue Boots & Coots’ welfare plans through December 31, 2010. Beginning on January 1, 2011, Boots & Coots’ continuing employees will be eligible to participate in Halliburton’s welfare plans without any pre-existing condition exclusions.

Reorganization. Each of Halliburton and Boots & Coots has agreed to use its reasonable best efforts to:


	•	cause the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code;

	•	refrain from taking any action reasonably likely to cause the merger not to so qualify; and

	•	obtain the specified tax opinions of its legal advisors and tax certificates of its officers.

Regulatory Filings and Related Matters. Pursuant to the merger agreement, Halliburton, Gradient and Boots & Coots have agreed to use commercially reasonable efforts to:


	•	as promptly as practicable, make their respective required filings with any governmental authorities and third parties with respect to the merger;

	•	obtain and maintain all approvals, consents, registrations, permits, authorizations and other confirmations required to be obtained from any governmental authorities or other third parties that are necessary, proper or advisable to complete the merger;

	•	resolve objections, if any, as may be asserted with respect to the merger under applicable law; and

	•	prevent the entry of, and to cause to be discharged or vacated, any order or injunction of a governmental entity that precludes, restrains, enjoins or prohibits the completion of the merger, provided that no party that becomes subject to any term, condition, obligation or restriction imposed by a governmental authority is required to dispose of any assets or limit its freedom of action that in Halliburton’s good faith judgment would be reasonably likely to give rise to a material adverse effect on a party or materially impair the benefits or advantages Halliburton expects to receive from the merger.

The parties have also agreed to furnish each other party with copies of all filings with, or any other information supplied to or received from, a governmental entity in connection with the merger.

Additional Agreements. Pursuant to the merger agreement, Halliburton, Gradient and Boots & Coots have also agreed:


	•	to promptly notify each other party of any fact, event or circumstance as to which it obtains knowledge that would be reasonably likely to result in a failure of a condition to the closing of the merger with


		respect to the accuracy of the representations and warranties made by such party or the performance of or compliance with such party’s obligations under the merger agreement;


	•	that, for a period of six years after the effective time of the merger, Gradient’s organizational documents will contain indemnification, exculpation and expense-advancement provisions that are no less favorable than those set forth in Boots & Coots’ organizational documents;

	•	that, for a period of six years after the effective time of the merger, Gradient will maintain Boots & Coots’ directors’ and officers’ liability insurance policies or substitute therefor policies on terms no less advantageous to such individuals, provided that Gradient will not be required to pay annual premiums in excess of 200% of the current annual premium being paid by Boots & Coots, but in that case Gradient will purchase as much coverage as possible for that amount;

	•	to not issue or cause the publication of any press release or other announcement or hold any press conferences, analyst calls or other meetings with respect to the merger, the merger agreement or the transactions contemplated by the merger agreement without the prior consultation of the other party, except as required by applicable law and applicable stock exchange listing arrangements; and

	•	pay all costs and expenses incurred by them in connection with the merger agreement, other than costs that are specified to be paid by one party under the merger agreement.

Pursuant to the merger agreement and in addition to the applicable covenants of Halliburton listed above, Halliburton also has agreed to use its reasonable best efforts to cause the Halliburton common stock issuable in connection with the merger to be listed on the NYSE, subject to official notice of issuance.

Pursuant to the merger agreement and in addition to the applicable covenants of Boots & Coots listed above, Boots & Coots also has agreed to:


	•	provide the authorized Representatives of Halliburton reasonable access to its properties, offices, contracts, books, commitments, records, data and personnel, to the extent permitted by applicable law and third-party agreements; and

	•	take all actions necessary to be taken such that no restrictive provision of any “moratorium,” “control share acquisition,” “fair price,” “interested shareholder,” “affiliate transaction,” “business combination” or other similar anti-takeover statute or law or any applicable anti-takeover provision in Boots & Coots’ organizational documents is, or at the effective time of the merger will be, applicable to the parties, Boots & Coots common stock, the merger agreement or the transactions contemplated by the merger agreement.

Termination, Amendment and Waiver

Termination

The merger agreement may be terminated at any time prior to the effective time of the merger, notwithstanding the adoption of the merger agreement by Boots & Coots’ stockholders:


	•	by mutual written consent of Halliburton and Boots & Coots;

	•	by either Halliburton or Boots & Coots if:


	•	the merger has not occurred on or before the “outside date,” which is October 1, 2010 or such later date agreed upon in writing, but neither party may terminate the merger agreement under this provision if that party’s failure to fulfill any material obligation under the merger agreement has caused or resulted in the failure of the merger to occur on or before the outside date; provided that the outside date will be extended to December 1, 2010 if all conditions other than the termination or expiration of the waiting period under the HSR Act or any statute requiring premerger notification have been fulfilled or are capable of being fulfilled;

	•	a governmental entity has issued a final, non-appealable statute, rule, order, decree or regulation or taken any other action, in each case permanently restraining, enjoining or otherwise prohibiting the merger, but neither party may terminate the merger agreement if its failure to fulfill any material obligation under the merger agreement has been the cause of or resulted in such action or if it materially breaches certain provisions of the merger agreement with respect to such action; or

	•	the Boots & Coots stockholders have failed to adopt the merger agreement at the Boots & Coots stockholder meeting;


	•	by Boots & Coots if Halliburton has breached or failed to perform any representation, warranty or covenant in the merger agreement such that the conditions to the closing of the merger agreement related to the accuracy of the representations and warranties or the performance of the covenants of Halliburton would fail and the breach or failure to perform is incapable of being cured prior to the outside date or is not cured within 30 days after Boots & Coots gives written notice of the breach or failure to perform to Halliburton, as long as Boots & Coots is not, at the time of the termination, in material breach or has materially failed to perform any of its representations, warranties or covenants in the merger agreement;

	•	by Boots & Coots if there is a change in the Boots & Coots board of directors’ recommendation, the Boots & Coots board of directors has authorized Boots & Coots to enter into an acquisition agreement in respect of a related superior proposal and Boots & Coots has paid or concurrently pays $10.0 million to Halliburton, provided Boots & Coots has not breached its covenants or other agreements in the merger agreement relating to no solicitation;

	•	by Halliburton if Boots & Coots has breached or failed to perform any representation, warranty or covenant in the merger agreement such that the conditions to the closing of the merger agreement related to the accuracy of the representations and warranties or the performance of the covenants of Boots & Coots would fail and the breach or failure to perform is incapable of being cured prior to the outside date or is not cured within 30 days after Halliburton gives written notice of the breach or failure to perform to Boots & Coots, as long as Halliburton is not, at the time of the termination, in


		material breach or has materially failed to perform any of its representations, warranties or covenants in the merger agreement;


	•	by Halliburton if (the following are collectively referred to as the “Halliburton termination events”):


	•	Boots & Coots has breached or failed to perform in any respect any of its covenants or other agreements relating to no solicitation and holding the Boots & Coots stockholder meeting (see “— Certain Additional Agreements”);

	•	a change in the Boots & Coots board of directors’ recommendation of the merger has occurred or the Boots & Coots board of directors or any committee thereof has resolved to make such a change;

	•	Boots & Coots has recommended, adopted or approved, or proposed publicly to recommend, adopt or approve, any acquisition proposal or acquisition agreement relating thereto;

Fees and Expense Reimbursement

Fees. The merger agreement provides for the payment of a termination fee by Boots & Coots to Halliburton if the agreement is terminated in specified circumstances.

Boots & Coots will be obligated to pay a $10.0 million termination fee to Halliburton if:


	•	Halliburton terminates the merger agreement because of a Halliburton termination event other than Boots & Coots breaching or failing to perform in any respect any of its covenants or other agreements relating to holding the Boots & Coots stockholder meeting (see “— Certain Additional Agreements”);

	•	the merger agreement is terminated by:


	•	Halliburton or Boots & Coots because the merger has not been consummated by the outside date;

	•	Halliburton or Boots & Coots because the Boots & Coots stockholders have failed to adopt the merger agreement at the Boots & Coots stockholder meeting; or

	•	Halliburton because Boots & Coots has breached or failed to perform any representation, warranty or covenant in the merger agreement such that the conditions to the closing of the merger agreement related to the accuracy of the representations and warranties or the performance of the covenants of Boots & Coots would fail and the breach or failure to perform is incapable of being cured prior to the outside date or is not cured within 30 days after Halliburton gives written notice of the breach or failure to perform to Boots & Coots, as long as Halliburton is not, at the time of the termination, in material breach or has materially failed to perform any of its representations, warranties or covenants in the merger agreement;

and, in the case of a termination of the merger agreement in any of the circumstances described in the preceding three bullet points, the following two conditions are also satisfied:


	•	prior to the termination, an acquisition proposal has been publicly announced or proposed or any person has announced its intention to make an acquisition proposal or such intention has otherwise become known to Boots & Coots’ stockholders generally; and

	•	within 365 days after the termination, Boots & Coots enters into any definitive agreement providing for an acquisition proposal or an acquisition proposal is consummated; or


	•	Boots & Coots terminates the merger agreement because there has been a change in the Boots & Coots board of directors’ recommendation, and the Boots & Coots board of directors has authorized Boots & Coots to enter into an acquisition agreement in respect of a related superior proposal, in which event Boots & Coots must have paid or concurrently pay the $10.0 million termination fee to Halliburton and must not have breached its covenants or other agreements in the merger agreement relating to no solicitation.

In the event of a termination of the merger agreement because of a Halliburton termination event (other than Boots & Coots breaching or failing to perform in any respect any of its covenants or other agreements relating to holding the Boots & Coots stockholder meeting), Boots & Coots must pay the termination fee within one business day after termination. In the event of any other termination that gives rise to the payment of a termination fee, unless otherwise stated above, Boots & Coots must pay the termination fee upon the earlier of the execution of an acquisition agreement or the consummation of the transactions contemplated by an acquisition proposal.

For purposes of this discussion regarding termination fees and expenses, the term “acquisition proposal,” means any proposal, whether or not in writing, for the


	•	direct or indirect acquisition or purchase of a business or assets that generates or constitutes 50% or more of the net revenues, net income or the assets of Boots & Coots and its subsidiaries, taken as a whole,

	•	direct or indirect acquisition or purchase of 50% or more of any equity securities or capital stock of Boots & Coots or any equity securities or capital stock of its subsidiaries that, individually or in the aggregate, represent a direct or indirect ownership interest in 50% or more of Boots & Coots’ consolidated assets, or

	•	merger, consolidation, restructuring, transfer of assets or other business combination, sale of shares of capital stock, tender offer, exchange offer, recapitalization, stock repurchase program or other similar transaction that if consummated would result in any person or persons beneficially owning 50% or more of the equity securities or capital stock of Boots & Coots or equity securities or capital stock of its subsidiaries that, individually or in the aggregate, represent a direct or indirect ownership interest in 50% or more of Boots & Coots’ consolidated assets,

in each case other than the transactions contemplated by the merger agreement.

Expenses. In general, each of Halliburton and Boots & Coots will bear its own expenses in connection with the merger agreement and the related transactions, except that Boots & Coots will pay all of the costs and expenses incurred in connection with the printing and mailing of the registration statement and this proxy statement/prospectus, and Halliburton will pay all of the SEC filing fees in respect of the registration statement and this proxy statement/prospectus and all of the fees of the proxy solicitor.

If the merger agreement is terminated under the circumstances relating to Boots & Coots’ breach of its representations and warranties (other than provisions relating to certain business practices) or failure to perform its covenants or the circumstances relating to Boots & Coots stockholders’ failure to approve the merger agreement at the stockholder meeting, each as described in the section above titled “— Termination,” Boots & Coots must pay Halliburton’s out-of-pocket expenses, including all fees and expenses payable to all legal, accounting, financial, public relations and other professional advisors arising out of, in connection with or related to the merger or the other transactions contemplated by the merger agreement, up to a maximum of $1.5 million in the aggregate. Boots & Coots must make such payment within one business day after the date of the termination. If Boots & Coots must pay Halliburton a termination fee and Boots & Coots is paying or has paid Halliburton for expenses, the amount of the termination fee will be offset by the amount of such expense payment.

If the merger agreement is terminated under the circumstances relating to Halliburton’s breach of its representations and warranties or failure to perform its covenants as described in the section above titled “— Termination,” Halliburton must pay Boots & Coots’ out-of-pocket expenses, including all fees and expenses payable to all legal, accounting, financial, public relations and other professional advisors arising out of, in connection with or related to the merger or the other transactions contemplated by the merger

agreement, up to a maximum of $1.5 million in the aggregate. Halliburton must make such payment within one business day after the date of the termination.

Amendment

Prior to the effective time of the merger, the merger agreement may be amended at any time by action of the parties’ respective boards of directors. However, if the merger agreement has been adopted by Boots & Coots’ stockholders, then no amendment can be made that by applicable law or stock exchange rules requires the further approval of Boots & Coots’ stockholders without receipt of that further approval.

Waiver

At any time prior to the effective time of the merger, each of Halliburton and Gradient, on the one hand, and Boots & Coots, on the other hand, may:


	•	extend the time for the performance of any obligations or other acts of the other party;

	•	waive any inaccuracies in the representations and warranties of the other party; or

	•	waive compliance with any agreement or condition for the benefit of that party.

Governing Law

The merger agreement is governed by and will be construed in accordance with the laws of the State of Delaware, without regard to the conflicts of law provisions of Delaware law that would cause the laws of other jurisdictions to apply.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

General

The following discussion summarizes certain material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of Boots & Coots common stock and is the opinion of Baker Botts L.L.P. and Thompson & Knight LLP insofar as it relates to matters of U.S. federal income tax law and legal conclusions with respect to those matters. The forms of opinions of counsel are included as exhibits to the registration statement of which this proxy statement/prospectus forms a part. The opinions of counsel are dependent on the accuracy of the statements, representations and assumptions upon which the opinions are based and are subject to the limitations, qualifications and assumptions set forth below and in the opinions. The following summary is not binding on the Internal Revenue Service. It is based upon the Code and the regulations, rulings and decisions thereunder in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect, and to differing interpretations. This summary addresses only those stockholders who hold their shares of Boots & Coots common stock as a capital asset within the meaning of Section 1221 of the Code and does not address all of the U.S. federal income tax consequences that may be relevant to particular Boots & Coots stockholders in light of their particular circumstances, or to Boots & Coots stockholders who are subject to special rules, such as:


	•	financial institutions;

	•	mutual funds;

	•	tax-exempt organizations;

	•	insurance companies;

	•	S corporations, partnerships or other pass through entities for U.S. federal income tax purposes;

	•	dealers in securities, commodities or foreign currencies;

	•	traders in securities who elect to apply a mark-to-market method of accounting;

	•	holders who are not U.S. holders, as defined below;

	•	persons subject to U.S. alternative minimum tax;

	•	persons who hold shares of Boots & Coots common stock as a hedge against currency risk or as part of a straddle, constructive sale, conversion or any other risk reduction transaction; or

	•	holders who acquired their shares of Boots & Coots common stock upon the exercise of options or similar derivative securities or otherwise as compensation.

In addition, tax consequences under state, local and foreign laws and U.S. federal laws other than U.S. federal income tax laws are not addressed herein. Boots & Coots stockholders are urged to consult their tax advisors as to the specific tax consequences of the merger to them, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws in their particular circumstances.

For purposes of this discussion, a U.S. holder means a beneficial owner of Boots & Coots common stock who is:


	•	an individual who is a citizen or resident of the United States;

	•	a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any political subdivision thereof;

	•	an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

	•	a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial


		decisions of the trust or (2) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

The U.S. federal income tax consequences of the merger to a partner in any entity or arrangement that is treated as a partnership for U.S. federal income tax purposes and holds Boots & Coots common stock generally will depend on the status of the partner and the activities of the partnership. Partners in a partnership that holds Boots & Coots common stock should consult their own tax advisors as to the specific tax consequences of the merger to them.

Qualification of the Merger as a Reorganization and Tax Opinions

Each tax opinion will be based on certain representations made by Halliburton and Boots & Coots, including factual representations and certifications contained in officers’ certificates to be delivered at closing by Halliburton and Boots & Coots. Whether the continuity of interest test will be satisfied depends primarily upon the fair market value of the Halliburton common stock as of the effective date of the merger. If the fair market value of Halliburton common stock issued pursuant to the merger is not at least 40% of the total consideration paid or payable to Boots & Coots stockholders (other than holders of Boots & Coots restricted stock) in exchange for their Boots & Coots common stock, the allocation of the merger consideration to be paid in cash and Halliburton common stock will change in the minimum amounts necessary to meet the continuity of interest test. See “Terms of the Merger Agreement — Per Share Merger Consideration.”

While the continuity of interest test depends on the fair market value of the Halliburton common stock as of the effective date of the merger, the number of shares of Halliburton common stock that Boots & Coots stockholders will receive in the merger will depend on the five-day average price of Halliburton common stock. Therefore, if the five-day average price of Halliburton common stock is different from the fair market value of Halliburton common stock valued as of the effective date of the merger, then for purposes of the continuity of interest test the number of shares of Halliburton common stock to be exchanged for Boots & Coots common stock will comprise a larger percentage (if the five-day average price is less than the fair market value of Halliburton common stock valued as of the effective date of the merger) or a smaller percentage (if the five-day average price is greater than the fair market value of Halliburton common stock valued as of the effective date of the merger) of the total consideration paid or payable to Boots & Coots shareholders than the percentage obtained using the five-day average price of Halliburton common stock.

Further, for purposes of computing whether at least 40% of the total consideration paid or payable to Boots & Coots stockholders is Halliburton common stock, tax counsel will consider shares of Boots & Coots restricted stock that are exchanged for Halliburton common stock in the merger to be treated for tax purposes as having been exchanged for cash. This is because the Boots & Coots restricted stock, which pursuant to the merger agreement vests immediately prior to the effective time of the merger, may not be treated as being held by Boots & Coots stockholders for tax purposes. As such, each share of Halliburton common stock actually received in exchange for Boots & Coots restricted stock in the merger will not be treated as a share of Halliburton common stock for purposes of measuring the total consideration paid or payable to Boots & Coots stockholders. For example, if the fair market value of a share of Halliburton common stock valued as of the effective date of the merger is equal to the Halliburton five-day average price, then a reallocation of the merger consideration would occur if more than approximately 60.9% of the shares of Boots & Coots restricted stock are exchanged for Halliburton common stock in the merger. As a result of elections to be made by Messrs. Winchester and Edwards to receive only Halliburton common stock in the merger (see “The Merger — Interests of Certain Persons in the Merger that May be Different from Your Interests — Change of Control Arrangements”), as of July 27, 2010, 1,122,764 shares, or approximately 35.4% of all such outstanding shares, of Boots & Coots restricted stock may be exchanged for Halliburton common stock but be treated as having been exchanged for cash solely for purposes of the continuity of interest test. Elections by

other holders of Boots & Coots restricted stock to receive Halliburton common stock in the merger, in addition to Messrs. Winchester and Edwards, may cause the number of shares of Boots & Coots restricted stock that are exchanged for Halliburton common stock in the merger to exceed the approximately 60.9% threshold described above.

Each tax opinion will assume that each of the representations and certifications noted in the preceding paragraph is true, correct and complete on the effective date of the merger without regard to any knowledge limitation. Furthermore, each tax opinion will be subject to certain other assumptions, limitations and qualifications. If any of the representations, certifications or assumptions relied upon in the tax opinions are inaccurate, incomplete or untrue, the tax opinions may not be relied upon, and the discussion below, which assumes that the merger will qualify as a “reorganization” under Section 368(a) of the Code, may not accurately describe the tax consequences of the merger. If any of these representations or assumptions are inconsistent with the actual facts, the U.S. federal income tax treatment of the merger could be adversely affected.

An opinion of counsel represents counsel’s best legal judgment and is not binding on the Internal Revenue Service or any court. No ruling has been, or will be, sought from the Internal Revenue Service as to the tax consequences of the merger. Accordingly, there can be no assurance that the Internal Revenue Service will not disagree with, or challenge any of, the conclusions set forth in the opinions or described herein or that a court would not sustain such a challenge.

Material U.S. Federal Income Tax Consequences if the Merger Qualifies as a Reorganization

Assuming that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, the merger is expected to have the following U.S. federal income tax consequences to Boots & Coots stockholders.

Boots & Coots Stockholders Receiving Only Halliburton Common Stock. No gain or loss will be recognized by a Boots & Coots stockholder as a result of the surrender of shares of Boots & Coots common stock solely in exchange for shares of Halliburton common stock pursuant to the merger, except as discussed below with respect to cash received instead of a fractional share of Halliburton common stock. The aggregate tax basis of the shares of Halliburton common stock received in the merger (including any fractional shares of Halliburton common stock deemed received and exchanged for cash) will be the same as the aggregate tax basis of the shares of Boots & Coots common stock surrendered in exchange for the Halliburton common stock. The holding period of the shares of Halliburton common stock received (including any fractional share of Halliburton common stock deemed received and exchanged for cash) will include the holding period of shares of Boots & Coots common stock surrendered in exchange for the Halliburton common stock.

Boots & Coots Stockholders Receiving Only Cash. A Boots & Coots stockholder that does not receive any shares of Halliburton common stock pursuant to the merger will recognize gain or loss equal to the difference between the amount of cash received and the holder’s adjusted tax basis in the shares of Boots & Coots common stock exchanged in the merger. Gain or loss will be computed separately with respect to each identified block (that is, stock acquired at the same time for the same price) of Boots & Coots common stock exchanged in the merger. Such gain or loss generally will be a capital gain or loss and will be a long-term capital gain or loss to the extent that, at the effective time of the merger, the holder has a holding period in the Boots & Coots common stock surrendered of more than one year. The deductibility of capital losses is subject to limitations. In some cases, if a holder actually or constructively owns Halliburton common stock immediately after the merger, the cash received could be treated as having the effect of the distribution of a dividend. See “— Boots & Coots Stockholders Receiving Both Cash and Halliburton Common Stock” below.

Boots & Coots Stockholders Receiving Both Cash and Halliburton Common Stock. If a Boots & Coots stockholder receives both Halliburton common stock and cash (other than cash received instead of a fractional share of Halliburton common stock) pursuant to the merger, that holder will recognize gain (but not loss) equal to the lesser of (a) the amount of cash received (excluding cash received instead of a fractional share of Halliburton common stock) and (b) the amount, if any, by which the sum of the amount of cash received and

the fair market value (as of the effective time of the merger) of the Halliburton common stock received exceeds the holder’s adjusted tax basis in the shares of Boots & Coots common stock exchanged in the merger. Gain may be computed separately with respect to each identified block of Boots & Coots common stock exchanged in the merger. If a holder of Boots & Coots common stock acquired different blocks of Boots & Coots common stock at different times or different prices, the holder should consult its tax advisor regarding the manner in which gain or loss should be determined.

Any recognized gain will be capital gain unless the holder’s exchange of Boots & Coots common stock for cash and Halliburton common stock has the effect of the distribution of a dividend. There are certain circumstances, generally involving a Boot & Coots stockholder who is also a substantial holder of Halliburton common stock (actually or constructively), in which all or part of the cash received by such holder would be treated as a dividend rather than as capital gain. In general, the determination as to whether the receipt of cash has the effect of a distribution of a dividend depends upon whether and to what extent the transactions related to the merger will be deemed to reduce a holder’s percentage ownership of Halliburton immediately following the merger. For purposes of that determination, a holder will be treated as if it first exchanged all of its Boots & Coots common stock solely for Halliburton common stock and then a portion of that stock was immediately redeemed by Halliburton for the cash (excluding cash received instead of a fractional share of Halliburton common stock) that the holder actually received in the merger. The Internal Revenue Service has indicated that any reduction in the interest of a minority stockholder that owns a small number of shares in a publicly and widely held corporation and that exercises no control over corporate affairs would result in capital gain (as opposed to dividend) treatment. In determining whether the receipt of cash has the effect of a distribution of a dividend, certain constructive ownership rules must be taken into account. Holders should consult their tax advisors about the possibility that all or a portion of any cash received in exchange for Boots & Coots common stock will be treated as a dividend, based on the holder’s specific circumstances (e.g., holders that are corporations should consult their tax advisors regarding the potential applicability of the “extraordinary dividend” provisions of the Code). Any recognized gain generally will be long-term capital gain to the extent that, at the effective time of the merger, the holder has a holding period in the Boots & Coots common stock exchanged in the merger of more than one year.

The aggregate tax basis to such a holder of the shares of Halliburton common stock received in the merger (including any fractional share of Halliburton common stock deemed received) will be the same as the aggregate tax basis of the shares of Boots & Coots common stock surrendered and exchanged for cash in the merger, increased by the amount of gain, if any, recognized (excluding gain recognized with respect to cash received in lieu of fractional shares) and reduced by the amount of cash received (excluding cash received instead of fractional shares). The holding period of the shares of Halliburton common stock received (including any fractional share of Halliburton common stock deemed received and exchanged for cash) will include the holding period of shares of Boots & Coots common stock surrendered in exchange for the Halliburton common stock.

Boots & Coots Stockholders Receiving Cash Instead of a Fractional Share. Boots & Coots stockholders who receive cash instead of fractional shares of Halliburton common stock will be treated as having received the fractional shares in the merger and then as having exchanged the fractional shares for cash. These holders generally will recognize gain or loss equal to the difference between the tax basis allocable to the fractional shares and the amount of cash received. The gain or loss will be capital gain or loss and long-term capital gain or loss if the Boots & Coots common stock exchanged has been held for more than one year at the effective time of the merger. The deductibility of capital losses is subject to limitations.

Material U.S. Federal Income Tax Consequences if the Merger Fails to Qualify as a Reorganization

If the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, then each Boots & Coots stockholder will recognize capital gain or loss equal to the difference between (1) the sum of the fair market value of the shares of Halliburton common stock, as of the effective date of the merger, and the amount of cash received pursuant to the merger (including cash received instead of fractional shares of Halliburton common stock) and (2) its adjusted tax basis in the shares of Boots & Coots common

stock surrendered in exchange therefor. Gain or loss will be computed separately with respect to each identified block of Boots & Coots common stock exchanged in the merger.

Further, if the merger is not treated as a “reorganization” within the meaning of Section 368(a) of the Code, Boots & Coots will be subject to tax on the deemed sale of its assets to Halliburton, with gain or loss for this purpose measured by the difference between Boots & Coots’ tax basis in its assets and the fair market value of the consideration deemed to be received therefor or, in other words, the cash and shares of Halliburton common stock plus liabilities assumed in the merger, and Halliburton will become liable for any tax liability of Boots & Coots resulting from the merger.

U.S. Federal Income Tax Consequences to Holders That Exercise Appraisal Rights

A U.S. holder who receives cash pursuant to the exercise of appraisal rights for its Boots & Coots common stock generally will recognize capital gain or loss measured by the difference between the cash received and its adjusted tax basis in such stock. Gain or loss will be computed separately with respect to each identified block of Boots & Coots common stock exchanged in the merger. Such gain or loss generally will be a capital gain or loss and will be a long-term capital gain or loss to the extent that, at the effective time of the merger, the holder has a holding period in the Boots & Coots common stock surrendered of more than one year. The deductibility of capital losses is subject to limitations. In some cases, if a holder actually or constructively owns Halliburton common stock immediately after the merger, the cash received could be treated as having the effect of the distribution of a dividend. See “— Boots & Coots Stockholders Receiving Both Cash and Halliburton Common Stock” above.

Backup Withholding; Information Reporting; Record Keeping

Under U.S. federal income tax laws, the exchange agent generally will be required to report to a Boots & Coots stockholder and to the Internal Revenue Service any reportable payments made to such Boots & Coots stockholder in the merger, and backup withholding (currently at a rate of 28%) may apply to such payment. To avoid such backup withholding, a Boots & Coots stockholder must provide the exchange agent with a properly completed Substitute Form W-9, signed under penalties of perjury, including such stockholder’s current Taxpayer Identification Number, or TIN, and other certifications. Certain Boots & Coots stockholders (including, among others, corporations) are exempt from these backup withholding and reporting requirements. Exempt holders who are not subject to backup withholding should indicate their exempt status on a Substitute Form W-9 by entering their correct TIN, marking the appropriate box and signing and dating the Substitute Form W-9 in the space provided.

Backup withholding is not an additional tax. Rather, the tax liability of a person subject to backup withholding may be reduced by the amount of tax withheld or a refund from the Internal Revenue Service may be obtained provided the requisite information is timely furnished to the Internal Revenue Service.

Each U.S. holder that receives Halliburton common stock as a result of the merger will be required to retain records pertaining to the merger. In addition, each U.S. holder that owns at least five percent of Boots & Coots’ common stock will be required to file with its U.S. federal income tax return for the year in which the merger occurs a statement setting forth certain facts relating to the merger, including such holder’s tax basis in its Boots & Coots common stock exchanged in the merger and the fair market value of such stock.

The foregoing discussion is not intended to be legal or tax advice to any particular Boots & Coots stockholder. Tax matters regarding the merger are very complicated and the tax consequences of the merger to any particular Boots & Coots stockholder will depend on that stockholder’s particular situation. Boots & Coots stockholders should consult their own tax advisors regarding the specific tax consequences of the merger, including tax return reporting requirements, the applicability of federal, state, local and foreign tax laws and the effect of any proposed change in the tax laws to them.

COMPARISON OF STOCKHOLDER RIGHTS

The rights of Halliburton stockholders are governed by Halliburton’s restated certificate of incorporation and by-laws, as amended, and the laws of the State of Delaware, and the rights of Boots & Coots stockholders are governed by Boots & Coots’ amended and restated certificate of incorporation and by-laws, each as amended, and the laws of the State of Delaware. After the merger, some or all Boots & Coots stockholders will become stockholders of Halliburton and, accordingly, their rights will be governed by Halliburton’s restated certificate of incorporation and by-laws and the laws of the State of Delaware. While the rights and privileges of Boots & Coots stockholders are, in many instances, comparable to those of the stockholders of Halliburton, there are some differences. These differences arise from differences between the respective certificates of incorporation and by-laws of Halliburton and Boots & Coots.

The following discussion summarizes the material differences as of the date of this document between the rights of Halliburton stockholders and the
