#### FORWARD-LOOKING INFORMATION
This prospectus, including the information we incorporate by reference, includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Exchange Act. Forward-looking information is based on projections and estimates, not historical information. You can identify our forward looking statements by the use of words like "may," "may not," "believes," "do not believe," "plans," "estimates," "intends," "expects," "do not expect," "anticipates," "do not anticipate," "should," "likely," and other similar expressions that convey the uncertainty of future events or outcomes.

When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements contained in this prospectus, any prospectus supplement and the documents we incorporate by reference.

Forward-looking information involves risk and uncertainties and reflects our best judgment based on current information. Our forward-looking statements are not guarantees of future performance, and we caution you not to rely unduly on them. We have based many of these forward-looking statements on expectations and assumptions about future events that may prove to be inaccurate. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. In addition, other known and unknown risks and factors may affect the accuracy of our forward-looking information. Our forward-looking statements speak only as of the date of this prospectus or as of the date they are made, and, except as otherwise required by applicable securities laws, we undertake no obligation to publicly update any of our forward-looking statements regardless of whether factors change as a result of new information, future events or for any other reason.

Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of short-term indebtedness.

#### **TABLE OF CONTENTS**

#### DESCRIPTION OF CAPITAL STOCK
The following description of Halliburton's common stock, preferred stock, certificate of incorporation and by-laws is a summary only and is subject to the complete text of Halliburton's certificate of incorporation and by-laws, which have been filed with the SEC and which are incorporated by reference into this prospectus. You should read Halliburton's certificate of incorporation and by-laws as currently in effect for more details regarding the provisions described below and for other provisions that may be important to you. This section also summarizes relevant provisions of the Delaware General Corporation Law ("DGCL"). The terms of the DGCL are more detailed than the general information provided below. Therefore, you should carefully consider the actual provisions of these laws.

Halliburton's authorized capital stock consists of 2,000,000,000 shares of common stock, par value $2.50 per share, and 5,000,000 shares of preferred stock, without par value. As of February 2, 2023, there were 904,120,447 shares of common stock issued and outstanding. No shares of preferred stock are outstanding.

#### Common Stock
The holders of Halliburton common stock are entitled to one vote per share on all matters to be voted on by stockholders generally, including the election of directors. There are no cumulative voting rights, meaning that the holders of a majority of the shares voting for the election of directors can elect all of the candidates standing for election.

Halliburton's common stock carries no preemptive or other subscription rights to purchase shares of Halliburton common stock and is not convertible, redeemable or assessable or entitled to the benefits of any sinking fund. Holders of Halliburton common stock will be entitled to receive such dividends as may from time to time be declared by Halliburton's Board of Directors (the "Board") out of funds legally available for the payment of dividends. If Halliburton issues preferred stock in the future, payment of dividends to holders of Halliburton common stock may be subject to the rights of holders of Halliburton preferred stock with respect to payment of preferential dividends, if any.

If Halliburton is liquidated, dissolved or wound up, the holders of Halliburton common stock will share pro rata in Halliburton's assets after satisfaction of all of its liabilities and the prior rights of any outstanding class of preferred stock.

Halliburton common stock is listed on the New York Stock Exchange under the symbol "HAL." Any additional common stock that Halliburton will issue will also be listed on the New York Stock Exchange.

#### Preferred Stock
The Board has the authority, without stockholder approval, to issue shares of preferred stock in one or more series and to fix the number of shares and terms of each series. The Board may determine the designation and other terms of each series, including, among others:

&nbsp;&nbsp;&nbsp;&nbsp;• dividend rights;

&nbsp;&nbsp;&nbsp;&nbsp;• voting powers;

&nbsp;&nbsp;&nbsp;&nbsp;• preemptive rights;

&nbsp;&nbsp;&nbsp;&nbsp;• conversion rights;

&nbsp;&nbsp;&nbsp;&nbsp;• redemption rights, including pursuant to a sinking fund;

&nbsp;&nbsp;&nbsp;&nbsp;• our purchase obligations, including pursuant to a sinking fund; and

&nbsp;&nbsp;&nbsp;&nbsp;• liquidation preferences.

The issuance of preferred stock, while providing desired flexibility in connection with possible acquisitions and other corporate purposes, could adversely affect the voting power of holders of Halliburton common stock. It also could affect the likelihood that holders of Halliburton common stock will receive dividend payments and payments upon liquidation. Shares of preferred stock may be offered either separately or represented by depositary shares.

#### **TABLE OF CONTENTS**

#### Anti-Takeover Provisions
Some provisions of Delaware law, Halliburton's certificate of incorporation and by-laws summarized below could make certain change of control transactions more difficult, including acquisitions of Halliburton by means of a tender offer, proxy contest or otherwise, as well as removal of Halliburton's incumbent directors. These provisions may have the effect of preventing changes in Halliburton's management. It is possible that these provisions would make it more difficult to accomplish or deter transactions that a stockholder might consider in his or her best interest, including those attempts that might result in a premium over the market price for the common stock.

#### Business Combinations Under Delaware Law
Halliburton is a Delaware corporation and is subject to Section 203 of the DGCL. Generally, Section 203 prevents (i) a person who owns 15% or more of Halliburton's outstanding voting stock (an "interested stockholder"), (ii) an affiliate or associate of Halliburton who was also an interested stockholder at any time within three years immediately prior to the date of determination and (iii) the affiliates and associates of any such persons from engaging in any business combination with Halliburton, including mergers or consolidations or acquisitions of additional shares, for three years following the date that the person became an interested stockholder. These restrictions do not apply if:

&nbsp;&nbsp;&nbsp;&nbsp;• before the person became an interested stockholder, the Board approved either the business combination or the transaction in which the interested stockholder became an interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of Halliburton voting stock that was outstanding at the time the transaction commenced, other than statutorily excluded shares; or

&nbsp;&nbsp;&nbsp;&nbsp;• on or subsequent to the time the stockholder became an interested stockholder, the business combination is approved by both the Board and the holders of at least two-thirds of Halliburton outstanding voting stock that is not owned by the interested stockholder.

#### Number and Election of Directors
Halliburton's by-laws provide that the number of directors shall not be less than 8 nor more than 20, with the number of directors to be fixed from time to time by or in the manner provided in the by-laws. Halliburton's by-laws provide that the number of directors shall be fixed by resolution of the Board or by the stockholders at the annual meeting, and that in the event of a vacancy or newly created directorship, the remaining directors have the sole power to fill any such vacancies.

#### Limitation of Stockholder Actions
Any Halliburton stockholder wishing to submit a nomination to the Board must follow certain procedures contained in Halliburton's by-laws. In addition, Halliburton's by-laws require written application by a holder of at least 10% of the outstanding Halliburton voting stock entitled to vote on the matter to be presented at the meeting or two or more holders owning in the aggregate at least 25% of the outstanding Halliburton voting stock entitled to vote on the matter to be presented at the meeting to call a special meeting of the Halliburton stockholders. Generally, a notice of a stockholder proposal or nomination of a director candidate is timely if it is received not less than 90 days nor more than 120 days prior to the first anniversary of the immediately preceding annual meeting. Halliburton's by-laws specify the requirements as to form and content of all stockholders' notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting to the extent they do not comply with the requirements in these advance notice procedures.

#### Authorized but Unissued Shares
Halliburton's certificate of incorporation provides that the authorized but unissued shares of preferred stock are available for future issuance without stockholder approval and does not preclude the future issuance without stockholder approval of the authorized but unissued shares of Halliburton's common stock. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could make it more difficult or discourage an attempt to obtain control of Halliburton by means of a proxy contest, tender offer, merger or otherwise.

6<br>

------

#### **TABLE OF CONTENTS**

#### Amendments to Halliburton's By-laws
Halliburton's by-laws may be amended or repealed or new by-laws may be adopted (i) by the affirmative vote of the majority of the Board or (ii) at any annual or special meeting of the stockholders where a quorum is present by the affirmative vote of the majority of the stockholders entitled to vote at such meeting.

#### Limitation of Director Liability and Indemnification Arrangements
Halliburton's by-laws contain provisions that provide for indemnification of officers and directors to the fullest extent permitted by, and in the manner permissible under, the DGCL, which empowers a Delaware corporation to indemnify any person who was or is or is threatened to be made a witness in or a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The indemnity may include expenses (including attorneys' fees), liabilities, judgments, fines, excise taxes, penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person's conduct was unlawful.

As permitted by the DGCL, Halliburton's certificate of incorporation contains a provision eliminating the personal liability of Halliburton's directors to Halliburton or Halliburton's stockholders for monetary damages for breach of fiduciary duty as a director, subject to certain exceptions. Halliburton's limitation of liability and indemnification provisions may discourage stockholders from bringing a lawsuit against directors or officers for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors or officers, even though such an action, if successful, might otherwise benefit Halliburton and stockholders of Halliburton.

#### Transfer Agent and Registrar
The transfer agent and registrar for Halliburton common stock is Computershare Shareowner Services LLC.

#### **TABLE OF CONTENTS**

#### DESCRIPTION OF THE DEBT SECURITIES
We plan to issue the debt securities under an indenture dated as of October 17, 2003 between us and The Bank of New York Mellon Trust Company, N.A. (as successor to JPMorgan Chase Bank), as trustee (the "indenture"). The terms of the debt securities include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

The debt securities to be issued will be our general unsecured obligations and will rank equally with all of our unsecured and unsubordinated debt.

We have summarized the provisions of the indenture below. You should read the indenture for more details regarding the provisions described below and for other provisions that may be important to you. We have filed the indenture with the SEC as an exhibit to the registration statement, and we will include any other instrument establishing the terms of any debt securities we offer as exhibits to a filing we will make with the SEC in connection with that offering. See "Where You Can Find More Information."

The definitions of capitalized terms used in this section without definition are set forth below under "— Definitions." In this description, the word "Halliburton," "we," "our" or "us" means only Halliburton Company and not any of its subsidiaries or other affiliates.

#### General
The indenture does not contain any financial covenants. In addition, we are not restricted under the indenture from paying dividends, making investments or issuing or repurchasing our securities. The indenture will not restrict our ability to incur additional indebtedness in the future, other than certain secured indebtedness as described below.

Other than the restrictions contained in the indenture on liens and sale/leaseback transactions described below under "— Covenants," the indenture does not contain any covenants or other provisions designed to protect holders of the debt securities in the event we participate in a highly leveraged transaction or upon a change of control. The indenture also does not contain provisions that give holders the right to require us to repurchase their securities in the event of a decline in our credit ratings for any reason, including as a result of a takeover, recapitalization or similar restructuring or otherwise.

We may issue the debt securities of any series in definitive form or as a book-entry security in the form of a global security registered in the name of a depositary we designate.

We may issue the debt securities in one or more series with various maturities. They may be sold at par, at a premium or with a discount, which may be substantial, below their stated principal amount. These debt securities may bear no interest or interest at a rate that at the time of issuance is below market rates. If we sell these types of debt securities, we will describe in the prospectus supplement any material United States federal income tax consequences and other special considerations relating to that series of debt securities.

#### Terms
The prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

&nbsp;&nbsp;&nbsp;&nbsp;• the title of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• the price at which we will issue the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• any limit on the aggregate principal amount of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• whether the debt securities will be issued in individual certificates to each holder or in the form of temporary or permanent global securities held by a depositary on behalf of holders;

&nbsp;&nbsp;&nbsp;&nbsp;• the date or dates on which the principal of and any premium on the debt securities will be payable;

&nbsp;&nbsp;&nbsp;&nbsp;• any interest rate, the date from which interest will accrue, interest payment dates and record dates for interest payments and the manner in which such payments will be made;

&nbsp;&nbsp;&nbsp;&nbsp;• whether and under what circumstances any additional amounts with respect to the debt securities will be payable;

&nbsp;&nbsp;&nbsp;&nbsp;• the place or places where payments on the debt securities will be payable;

We may sell the debt securities at a discount, which may be substantial, below their stated principal amount.

#### Covenants
Under the indenture, there are no covenants restricting our ability to incur additional debt (other than certain secured indebtedness as described below), pay dividends, make investments, issue or repurchase our securities, maintain any asset or other ratios or create or maintain any reserves. However, the indenture does contain other covenants for your protection, including those described below.

We are required to deliver to the trustee, within 120 days after the end of each fiscal year, a statement signed by an officer complying with the applicable provisions of the Trust Indenture Act and stating that we have complied with every covenant contained in the indenture and are not in default in the performance or observance of any terms of the indenture.

The covenants summarized below will apply to the debt securities (unless waived or amended) as long as the debt securities are outstanding.

#### Restrictions on Secured Debt
Except as provided below, we will not, and will not cause, suffer or permit any of our Restricted Subsidiaries to, create, incur or assume any Secured Debt without equally and ratably securing the debt securities. In that circumstance, we must also equally and ratably secure any of our other indebtedness or any indebtedness of such Restricted Subsidiary then similarly entitled for so long as such other indebtedness is secured. However, the foregoing restrictions will not apply to:

&nbsp;&nbsp;&nbsp;&nbsp;• specified purchase money mortgages;

&nbsp;&nbsp;&nbsp;&nbsp;• specified mortgages to finance construction on unimproved property;

9<br>

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• mortgages existing on property at the time of its acquisition by us or a Restricted Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;• mortgages existing on the property or on the outstanding shares or indebtedness of a corporation at the time it becomes a Restricted Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;• mortgages on property of a corporation existing at the time the corporation is merged or consolidated with us or a Restricted Subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;• mortgages in favor of governmental bodies to secure payments pursuant to any contract or statute or to secure indebtedness for the purpose of financing the purchase or construction of the property subject to the mortgages; or

&nbsp;&nbsp;&nbsp;&nbsp;• extensions, renewals or replacement of the foregoing; provided that their extension, renewal or replacement must secure the same property and additions thereto and does not create Secured Debt in excess of the principal amount then outstanding securing such property.

We and any Restricted Subsidiaries may create, incur or assume Secured Debt not otherwise permitted or excepted without equally and ratably securing the debt securities if the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;• the amount of the Secured Debt together with all other Secured Debt of us and the Restricted Subsidiaries (not including Secured Debt permitted under the foregoing exceptions), plus

&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate value of Sale and Leaseback Transactions in existence at the time (not including Sale and Leaseback Transactions the proceeds of which have been or will be applied to the retirement of funded indebtedness of us and our Restricted Subsidiaries as described below under "— Limitations on Sale and Leaseback Transactions"),

does not at the time exceed 5% of Consolidated Net Tangible Assets.

#### Limitations on Sale and Leaseback Transactions
The indenture prohibits Sale and Leaseback Transactions unless:

&nbsp;&nbsp;&nbsp;&nbsp;• Halliburton or the Restricted Subsidiary owning the Principal Property would be entitled to incur Secured Debt equal to the amount realizable upon the sale or transfer secured by a mortgage on the property to be leased without equally and ratably securing the debt securities; or

&nbsp;&nbsp;&nbsp;&nbsp;• Halliburton or a Restricted Subsidiary apply an amount equal to the value of the property so leased to the retirement (other than mandatory retirement), within 120 days of the effective date of any such arrangement, of indebtedness for money borrowed by Halliburton or any Restricted Subsidiary (other than such indebtedness owned by Halliburton or any Restricted Subsidiary) which was recorded as funded debt as of the date of its creation and which, in the case of such indebtedness of Halliburton, is not subordinate and junior in right of payment to the prior payment of the debt securities.

*Provided, however, that the amount to be so applied to the retirement of such indebtedness shall be reduced by:* 

&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate principal amount of any debt securities delivered within 120 days of the effective date of any such arrangement to the trustee for retirement and cancellation; and

&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate principal amount of such indebtedness (other than the debt securities) retired by Halliburton or a Restricted Subsidiary within 120 days of the effective date of such arrangement.

Unless a Principal Property is designated as such by our Board, the limitation on Sale and Leaseback Transactions will not limit or prohibit any Sale and Leaseback Transactions by Halliburton or a Restricted Subsidiary.

#### Restrictions on Consolidation, Merger, Sale or Conveyance
Halliburton will not, in any transaction or series of transactions, consolidate with or merge with or into, or sell, convey, transfer, lease or otherwise dispose of all or substantially all its assets to, any person, unless:

(1) either (a) Halliburton shall be the continuing person or (b) the person (if other than Halliburton) formed by such consolidation or into which Halliburton is merged, or to which such sale, lease, conveyance, transfer or other disposition shall be made is organized and validly existing under the laws of the United States, any political subdivision thereof or any State of the United States or the District of Columbia and the successor 

10<br>

#### **TABLE OF CONTENTS**
company (if not Halliburton) will expressly assume, by supplemental indenture, the due and punctual payment of the principal of, premium (if any) and interest on the debt securities and the performance of all the obligations of Halliburton under the debt securities and the indenture;

(2)<br> immediately after giving effect to such transaction or series of transactions, no default or event of default (as described below) shall have occurred and be continuing or would result from the transaction; and

(3)<br> Halliburton delivers to the trustee the certificates and opinions required by the indenture.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more subsidiaries of Halliburton, which properties and assets, if held by Halliburton instead of such subsidiaries, would constitute all or substantially all of the properties and assets of Halliburton on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of Halliburton.

The successor company will succeed to, and be substituted for, and may exercise every right and power of, Halliburton under the indenture. In the case of a sale, conveyance, transfer or other disposition (other than a lease) of all or substantially all its assets, Halliburton will be released from all of the obligations under the indenture and the debt securities.

If any Principal Property becomes subject to any mortgage, security interest, pledge, lien or encumbrance not permitted under "— Restrictions on Secured Debt" upon any such consolidation with or merger with or into, or upon any such sale, conveyance, or lease or upon the acquisition by us of the properties of another corporation, the principal and interest payments on the debt securities will be secured by a direct lien on such Principal Property.

Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the property or assets of a person.

#### Events of Default
The following are events of default under the indenture:

&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay any interest or additional interest amounts, if any, when due, that continues for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay principal or premium, if any, or to deposit sinking fund payments, if any, when due;

&nbsp;&nbsp;&nbsp;&nbsp;• breach or failure to perform any other covenant or agreement in the indenture applicable to the debt securities of any series (other than any agreement or covenant that has been included in the indenture and any other supplement thereto solely for the benefit of other series of debt securities issued under the indenture and any other supplement thereto), which continues for 60 days after written notice of such failure by the trustee or the holders of at least 25% in aggregate principal amount of all affected debt securities then outstanding;

&nbsp;&nbsp;&nbsp;&nbsp;• failure to make any payment at maturity on any indebtedness, upon redemption or otherwise, in the aggregate principal amount of $125 million or more, after the expiration of any applicable grace period, and such amount has not been paid or discharged within 30 days after notice is given in accordance with the terms of such indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;• the acceleration of any indebtedness in the aggregate principal amount of $125 million or more so that it becomes due and payable prior to the date on which it would otherwise become due and payable and such acceleration is not rescinded within 30 days after notice is given in accordance with the terms of such indebtedness; and

&nbsp;&nbsp;&nbsp;&nbsp;• specific events relating to our bankruptcy, insolvency or reorganization, whether voluntary or not.

A default under one series of debt securities will not necessarily be a default under any other series of debt securities issued under the indenture.

If any event of default occurs for any series of debt securities and continues for the required amount of time, the trustee or the holders of not less than 25% of the principal amount of the then-outstanding debt securities of that series (or, if the event of default is due to the breach or failure to perform certain covenants or agreements in the

11<br>

------

#### **TABLE OF CONTENTS**
indenture, 25% in principal amount of all debt securities issued under the indenture and any supplement thereto that are affected, voting as one class) may declare the debt securities of that series due and payable, together with all accrued and unpaid interest, if any, immediately by giving notice in writing to us (and to the trustee, if given by the holders). Notwithstanding the preceding, in the case of an event of default arising from certain events of bankruptcy, insolvency or reorganization with respect to Halliburton, all outstanding debt securities of that series will become due and payable without further action or notice. The holders of a majority in principal amount of the then outstanding debt securities of that series (or, if the event of default is due to the breach or failure to perform certain covenants or agreements in the indenture, of all securities issued under the indenture and any supplement thereto that are affected, voting as one class), may rescind the declaration under circumstances specified in the indenture.

No holder of a debt security then outstanding may institute any suit, action or proceeding with respect to, or otherwise attempt to enforce, the indenture, unless:

&nbsp;&nbsp;&nbsp;&nbsp;• the holder has given to the trustee written notice of the occurrence and continuance of a default for the debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;• the holders of at least 25% in principal amount of the then-outstanding debt securities of that series have made a written request to the trustee to institute the suit, action or proceeding and have offered to the trustee the reasonable indemnity it may require; and

&nbsp;&nbsp;&nbsp;&nbsp;• the trustee for 60 days after its receipt of the notice, request and offer of indemnity has neglected or refused to institute the requested action, suit or proceeding, and during that 60 day period the holders of a majority in principal amount of the then-outstanding debt securities of that series do not give the trustee a direction inconsistent with the request.

The right of each holder of a debt security to receive payment of the principal of, premium, if any, or interest on a debt security on or after the respective due dates and the right to institute suit for enforcement of any payment obligation may not be impaired or affected without the consent of that holder.

The holders of a majority in aggregate principal amount of the then-outstanding debt securities of a series that are affected, voting as a class (or, in some cases, all the then-outstanding debt securities issued under the indenture and any supplement thereto that are affected, voting as a class), may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust power conferred on the trustee if that direction is not in conflict with applicable law and would not involve the trustee in personal liability.

#### Satisfaction and Discharge
The indenture provides that the trustee will execute proper instruments acknowledging the satisfaction and discharge of the indenture with respect to debt securities of any series when:

&nbsp;&nbsp;&nbsp;&nbsp;• all outstanding debt securities of such series have been delivered to the trustee for cancellation; or

&nbsp;&nbsp;&nbsp;&nbsp;• all outstanding debt securities of such series not delivered to the trustee for cancellation have (1) become due and payable; (2) will become due and payable at their stated maturity within one year; or (3) are to be called for redemption within one year under arrangements satisfactory to the trustee for giving of notice of redemption by the trustee in our name and at our expense.

In the case of satisfaction and discharge of debt securities not delivered to the trustee for cancellation, we must (1) deposit funds, government securities or a combination thereof with the trustee sufficient to make payments on the series of debt securities on the dates those payments are due and payable or (2) fulfill such other means of satisfaction and discharge specified in the supplemental indenture to such series of debt securities.

We must also pay all other sums due under the indenture and provide an officers' certificate and an opinion of counsel as described in the indenture.

12<br>

#### **TABLE OF CONTENTS**

#### Defeasance
When we use the term defeasance, we mean discharge from some or all of our obligations under the indenture. If, among other things, funds or government securities (or any combination thereof) are deposited with the trustee sufficient to make payments on the debt securities of any series on the dates those payments are due and payable, then, at our option, either of the following will occur:

&nbsp;&nbsp;&nbsp;&nbsp;• we will be discharged from our obligations with respect to the debt securities of that series ("legal defeasance"); or

&nbsp;&nbsp;&nbsp;&nbsp;• we will no longer have any obligation to comply with the restrictive covenants, the merger covenant and other specified covenants under the indenture, and the related events of default will no longer apply ("covenant defeasance").

If the debt securities of any series are defeased, the holders of the debt securities of that series will not be entitled to the benefits of the indenture, except for obligations to register the transfer or exchange of debt securities of that series, replace stolen, lost or mutilated debt securities of that series or maintain paying agencies and hold moneys for payment in trust. In the case of covenant defeasance, our obligation to pay principal, premium and interest on the debt securities of that series will also survive. Defeasance will not release us from certain of our obligations to the Trustee.

We will be required to deliver to the trustee an opinion of counsel or a tax ruling that the deposit and related defeasance would not cause the holders of the debt securities of any affected series to recognize income, gain or loss for U.S. federal income tax purposes and that holders will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect. We will also be required to provide the Trustee additional documents as described in the indenture.

#### Modifications
We and the trustee may amend or supplement the indenture if holders of a majority in principal amount of all then outstanding series of debt securities issued under the indenture and any supplement thereto that are affected by the amendment or supplement (acting as one class) consent to it. Without the consent of each holder of a debt security, however, no modification may:

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage stated above of the holders who must consent to an amendment or supplement to, or waiver of, the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the rate or change the time of payment of interest, including default interest, on any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of the principal of any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;• reduce the amount of the principal of, premium, if any, or mandatory sinking fund payment, if any, on any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;• reduce any premium payable on the redemption of any debt security or change the time at which any debt security may be redeemed;

&nbsp;&nbsp;&nbsp;&nbsp;• change any obligation to pay additional amounts;

&nbsp;&nbsp;&nbsp;&nbsp;• change the coin or currency in which principal, premium, if any, interest and additional amounts are payable to the holder;

&nbsp;&nbsp;&nbsp;&nbsp;• impair or affect the right to institute suit for the enforcement of any payment of principal of, premium, if any, or interest on or additional amounts with respect to any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;• make any change in the percentage of principal amount of debt securities necessary to waive compliance with specified provisions of the indenture; or

&nbsp;&nbsp;&nbsp;&nbsp;• waive a continuing default or event of default in payment of principal, premium, if any, or interest on or any additional amounts with respect to the debt securities.

13<br>

#### **TABLE OF CONTENTS**
From time to time, we and the trustee may enter into supplemental indentures without the consent of the holders of any debt security to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;• cure any ambiguity, omission, defect or any inconsistency in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• evidence the assumption by a successor entity of our obligations under the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;• provide for uncertificated debt securities in addition to or in place of certificated debt securities or to provide for the issuance of bearer securities;

&nbsp;&nbsp;&nbsp;&nbsp;• secure the debt securities or add guarantees of, or additional obligors on, the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• comply with any requirement in order to effect or maintain the qualification of the indenture under the Trust Indenture Act;

&nbsp;&nbsp;&nbsp;&nbsp;• add covenants or new events of default for the protection of the holders of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;• amend the indenture in any other manner that we may deem necessary or desirable and that will not adversely affect the interests of the holders of outstanding debt securities of any series of debt securities; or

&nbsp;&nbsp;&nbsp;&nbsp;• evidence the acceptance of appointment by a successor trustee.

We will be required to provide the Trustee with an opinion of counsel and an officers' certificate prior to the execution of any amendment or supplement to the indenture.

In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

#### **TABLE OF CONTENTS**

#### PLAN OF DISTRIBUTION
We may sell the securities in and outside the United States through underwriters or dealers, directly to purchasers or through agents.

#### Sale Through Underwriters or Dealers
If we use underwriters in the sale of the securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer the securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to conditions, and the underwriters will be obligated to purchase all of the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

If we use dealers in the sale of the securities, we will sell such securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

#### Rights Offerings
We may offer rights to our existing stockholders to purchase additional shares of our common stock, preferred stock, debt securities, depositary shares or other securities. For any particular subscription rights, the applicable prospectus supplement will describe the terms of such rights, including the period during which such rights may be exercised, the manner of exercising such rights, the transferability of such rights and the number of shares of common stock, preferred stock, debt securities, depositary shares or other securities that may be purchased in connection with each right and the subscription price for the purchase of such shares. In connection with a rights offering, we may enter into a standby arrangement with one or more underwriters or other purchasers to purchase any of our shares of common stock, preferred stock, debt securities, depositary shares or other securities not subscribed for in the rights offering by existing stockholders, which will be described in the applicable prospectus supplement.

#### Direct Sales and Sales Through Agents
We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.

#### Delayed Delivery Contracts
If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase the securities from us at the public offering price under delayed delivery

#### **TABLE OF CONTENTS**
contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

#### General Information
We may have agreements with the agents, dealers and underwriters to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Agents, dealers and underwriters may engage in transactions with us or perform services for us in the ordinary course of their businesses.

#### LEGAL MATTERS
The validity of the offered securities and other matters in connection with any offering of the securities will be passed upon for us by Baker Botts L.L.P., Dallas, Texas and Houston, Texas. If the securities are being distributed through underwriters or agents, the underwriters or agents will be advised about legal matters relating to any offering by their own legal counsel, which will be named in the related prospectus supplement.

#### EXPERTS
The consolidated financial statements of Halliburton Company as of December 31, 2022 and 2021, and for each of the years in the three-year period ended December 31, 2022, and management's assessment of the effectiveness of internal control over financial reporting as of December 31, 2022 have been incorporated by reference herein in reliance upon the reports of KPMG LLP, independent registered public accounting firm, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing.

| **Item 15.**<br>| ***Indemnification of Directors and Officers*** |

---

The discussion below summarizes the material indemnification provisions of Halliburton's restated certificate of incorporation and by-laws and Section 145 of the General Corporation Law of the State of Delaware (the "DGCL").

Section 145 of the DGCL provides that a Delaware corporation has the power, under specified circumstances, to indemnify its directors, officers, employees, and agents or persons who are or were serving at the request of the corporation as directors, officers, employees or agents of another entity. Indemnification is allowed in connection with threatened, pending, or completed actions, suits, or proceedings, whether civil, criminal, administrative or investigative, other than an action by or in right of the corporation, brought against them by reason of the fact that they were or are directors, officers, employees, or agents, for expenses, judgments and fines, and amounts paid in settlement actually and reasonably incurred in any action, suit, or proceeding if: (1) he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and (2) with respect to any criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that a person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Article X of Halliburton's restated certificate of incorporation provides for mandatory indemnification of each person who was or is or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that the person is or was a director, officer, employee or agent of Halliburton, or is or was serving at the request of Halliburton as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

Section 35 of Halliburton's by-laws provides for mandatory indemnification, to the fullest extent permitted by the DGCL as it existed at the time the indemnification provisions of Halliburton's by-laws were adopted or as it is thereafter amended, of each person who was or is or is threatened to be made a witness in or a party to any action, suit, arbitration, alternative dispute resolution mechanism, investigation, administrative hearing or any other proceeding, whether civil, criminal, administrative, or investigative because:

&nbsp;&nbsp;&nbsp;&nbsp;• the person is or was an officer or director of Halliburton;

PART II-1<br>

------

#### **TABLE OF CONTENTS**
&nbsp;&nbsp;&nbsp;&nbsp;• the person is an employee or agent of Halliburton (and not also a director or officer of Halliburton) and the Board adopts a resolution specifically stating that such person shall be entitled to some or all of the benefits of Section 35 of Halliburton's by-laws (an "Other Indemnified Person"); or

&nbsp;&nbsp;&nbsp;&nbsp;• is a director, officer or Other Indemnified Person who is or was serving at the request of Halliburton as a director, officer, or administrator of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Section 35 of Halliburton's by-laws and Article X of its restated certificate of incorporation expressly provide that they are not the exclusive methods of indemnification.

Section 145 of the DGCL provides that a Delaware corporation has the power to purchase and maintain insurance on behalf of its directors, officers, employees or agents against liabilities asserted against such person in his or her capacity or arising out of his or her status as a director, officer, employee or agent of the company. A Delaware corporation has this power whether or not the corporation has the power to indemnify such person against the liability under Section 145 of the DGCL.

Section 35 of the by-laws provides that Halliburton may maintain insurance, at its own expense, to protect itself and any person, including any person who is or was a director, officer, employee or agent of Halliburton or of another entity, against any expense, liability, or loss. This insurance coverage may be maintained regardless of whether Halliburton would have the power to indemnify such person against the expense, liability, or loss under the DGCL.

Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer. However, that provision shall not eliminate or limit the liability of:

&nbsp;&nbsp;&nbsp;&nbsp;• a director or officer for any breach of the director's or officer's duty of loyalty to the corporation or its stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;• a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

&nbsp;&nbsp;&nbsp;&nbsp;• a director under Section 174 of the DGCL, relating to liability for unlawful acquisitions or redemptions of, or payment of dividends on, capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;• a director or officer for any transaction from which the director or officer derived an improper personal benefit; or

&nbsp;&nbsp;&nbsp;&nbsp;• an officer in any action by or in the right of the corporation.

Article XV of Halliburton's restated certificate of incorporation provides that, to the fullest extent permitted by the DGCL, no director shall be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director.

The foregoing statements are subject to the detailed provisions of Sections 145 and 102 of the DGCL and Halliburton's restated certificate of incorporation and by-laws.

| **Item 17.**<br>| ***Undertakings***  |

---

(a)<br> The undersigned Registrant hereby undertakes:

(1)<br> To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)<br> To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and 

(iii)<br> To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

*provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by a Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.* 

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 

(3)<br> To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

PART II-3<br>

------

(4)<br> That, for the purpose of determining liability under the Securities Act to any purchaser:

(i)<br> Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date. 

(5) That, for the purpose of determining liability of the Registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of such undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, such undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: 

(i)<br> Any preliminary prospectus or prospectus of such undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)<br> Any free writing prospectus relating to the offering prepared by or on behalf of such undersigned Registrant or used or referred to by such undersigned Registrant;

(iii)<br> The portion of any other free writing prospectus relating to the offering containing material information about such undersigned Registrant or its securities provided by or on behalf of such undersigned Registrant; and

(iv)<br> Any other communication that is an offer in the offering made by such undersigned Registrant to the purchaser.

(b) The undersigned Registrant hereby further undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of such Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, such Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

PART II-4<br>

------

(d) The undersigned Registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act. 

PART II-5<br>

Halliburton Company

Houston, TX 77032

Ladies and Gentlemen:

We have acted as counsel to Halliburton Company, a Delaware corporation (the "<u>Company</u>"), with respect to certain legal matters in connection with the registration statement on Form S–3 (the "<u>Registration Statement</u>") to be filed by the Company with the Securities and Exchange Commission (the "<u>Commission</u>") under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), registering securities to be issued and sold from time to time pursuant to Rule 415 of the Securities Act. Such securities include: (a) shares of common stock, par value $2.50 per share, of the Company ("<u>Common Stock</u>"), (b) shares of preferred stock, without par value, of the Company ("<u>Preferred Stock</u>"), (c) debt securities of the Company ("<u>Debt Securities</u>"), which may be issued in one or more series, consisting of notes, debentures or other evidences of indebtedness, (d) depositary shares of the Company representing Preferred Stock ("<u>Depositary Shares</u>"), (e) warrants for the purchase of Common Stock, Preferred Stock, Debt Securities, Depositary Shares, Purchase Contracts (as defined below), other securities of the Company or any combination thereof ("<u>Warrants</u>"), (f) rights to purchase Common Stock, Preferred Stock, Debt Securities or other securities of the Company ("<u>Rights</u>"), (g) purchase contracts to purchase from or sell to the Company shares of Common Stock, Preferred Stock or other securities of the Company ("<u>Purchase Contracts</u>") and (h) units consisting of any combination of the Common Stock, Preferred Stock, Debt Securities, Depositary Shares, Warrants, Rights or Purchase Contracts ("<u>Units</u>" and, together with Common Stock, Preferred Stock, Debt Securities, Depositary Shares, Warrants, Rights and Purchase Contracts, the "<u>Securities</u>").

The Securities may be issued and sold or delivered as set forth in the Registration Statement, any amendment thereto, the prospectus contained therein (the "<u>Prospectus</u>"), and prospectuses supplementing the Prospectus or prospectuses which provide information supplementing the Prospectus (the "<u>Prospectus Supplements</u>").

Each series of Debt Securities will be issued pursuant to an Indenture (the "<u>Indenture</u>") dated as of October 17, 2003 between the Company and The Bank of New York Mellon Trust Company, N. A. (as successor to JPMorgan Chase Bank), as trustee (the "<u>Trustee</u>"). The Indenture will be supplemented, in connection with the issuance of each such series of Debt Securities, by a supplemental indenture, officers' certificate or other writing thereunder (each, a "<u>Supplemental Indenture Document</u>") establishing the form and terms of such series of Debt Securities.

At your request, this opinion is being furnished to you for filing as Exhibit 5.1 to the Registration Statement.

In our capacity as your counsel in the connection referred to above and as a basis for the opinions hereinafter expressed, we have examined originals, or copies certified or otherwise identified, of (a) the Restated Certificate of Incorporation of the Company, as amended to date (the "<u>Certificate of Incorporation</u>"), (b) the By-laws of the Company, as amended to date (the "<u>By-laws</u>" and together with the Certificate of Incorporation, the "<u>Charter Documents</u>"), (c) the Indenture, (d) the corporate records of the Company, including minute books of the Company as furnished to us by the Company, certificates of public officials and of representatives of the Company, statutes and other instruments and documents and (f) the Registration Statement and the Prospectus. In giving such opinions below, we have relied, to the extent we deemed proper, without independent investigation, upon certificates, statements and other representations of officers and other representatives of the Company and of governmental and public officials with respect to the accuracy and completeness of the material factual matters contained therein or covered thereby.

In making our examination, we have assumed, without independent investigation, that each document submitted to us for review is accurate and complete, each such document that is an original is authentic and complete, each such document that is a copy conforms to an authentic original and all signatures on each such document are genuine.

In connection with the opinions hereinafter expressed, we have also assumed that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Registration Statement and any amendments thereto (including post-effective amendments) will have become effective under the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) a Prospectus Supplement will have been prepared and filed with the Commission describing the Securities offered thereby;
