This prospectus is part of a registration statement that we have filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”) using a “shelf” registration process. Using this process, we may offer the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we use this prospectus to offer securities, we will provide a prospectus supplement and, if applicable, a pricing supplement that will describe the specific terms of the offering. The prospectus supplement and any pricing supplement may also add to, update or change the information contained in this prospectus.

Cautionary Statement Concerning Forward-Looking Statements

This prospectus and any accompanying prospectus supplement, including the information we incorporate by reference, include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 (the “Securities Act”) and Section 21E of the Exchange Act. You can identify our forward-looking statements by the words “anticipate,” “believe,” “expect,” “plan,” “intend,” “estimate,” “project,” “projection,” “predict,” “budget,” “forecast,” “goal,” “guidance,” “target,” “could,” “should,” “may,” and similar expressions.

These forward-looking statements include, among other things, statements regarding:

We based our forward-looking statements on our current expectations, estimates and projections about ourselves and our industry. We caution that these statements are not guarantees of future performance and involve risks, uncertainties and assumptions that we cannot predict. In addition, we based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in the forward-looking statements. Differences between actual results and any future performance suggested in these forward-looking statements could result from a variety of factors, including the following:

2

3

Any one of these factors, or a combination of these factors, could materially affect our future results of operations and whether any forward-looking statements ultimately prove to be accurate. Our forward-looking statements are not guarantees of future performance, and actual results and future performance may differ materially from those suggested in any forward-looking statements. We do not intend to update these statements unless we are required by the securities laws to do so.

Risk Factors

Investing in our securities involves significant risks. Before making an investment decision, you should carefully consider the risks and other information we include or incorporate by reference in this prospectus. In particular, you should consider the risk factors set forth in our most recent Annual Report on Form 10-K filed with the SEC, as those risk factors are amended or supplemented by subsequent Quarterly Reports on Form 10-Q and other reports and documents we file with the SEC after the date of this prospectus that are incorporated by reference herein. The risks and uncertainties we have described are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. Additional risk factors may be included in a prospectus supplement relating to a particular offering of securities.

Valero Energy Corporation

We are a Fortune 500 company based in San Antonio, Texas. We were incorporated in Delaware in 1981 under the name Valero Refining and Marketing Company. We changed our name to Valero Energy Corporation on August 1, 1997. Our common stock trades on the New York Stock Exchange (“NYSE”) under the symbol “VLO.” On January 31, 2018, we had 10,015 employees.

We own 15 petroleum refineries located in the United States (U.S.), Canada, and the United Kingdom (U.K.) with a combined throughput capacity of approximately 3.1 million barrels per day. Our refineries produce conventional gasolines, premium gasolines, gasoline meeting the specifications of the California Air Resources Board (CARB), diesel, low-sulfur diesel, ultra-low-sulfur diesel, CARB diesel, other distillates, jet fuel, asphalt, petrochemicals, lubricants, and other refined petroleum products. We sell our refined petroleum products in both the wholesale rack and bulk markets, and approximately 7,400 outlets carry our brand names in the U.S., Canada, the U.K., and Ireland. Most of our logistics assets support our refining operations, and some of these assets are owned by Valero Energy Partners LP (VLP), a midstream master limited partnership majority owned by us. We also own 11 ethanol plants in the Mid-Continent region of the U.S. with a combined production capacity of approximately 1.45 billion gallons per year. We sell our ethanol in the wholesale bulk market, and some of our logistics assets support our ethanol operations.

Our principal executive offices are located at One Valero Way, San Antonio, Texas, 78249, and our telephone number is (210) 345-2000.

Use of Proceeds

We intend to use the net proceeds from the sales of the securities for general corporate purposes unless otherwise set forth in the applicable prospectus supplement.

Ratios of Earnings to Fixed Charges

Our ratios of earnings to fixed charges for each of the periods indicated are as follows:

4

We have computed the ratio of earnings to fixed charges by dividing earnings by fixed charges. For these purposes, earnings consist of income from continuing operations before income tax expense and fixed charges (excluding interest capitalized), with certain other adjustments. Fixed charges consist of interest, whether expensed or capitalized, debt expense and one-third (the proportion deemed representative of the interest factor) of rental expense.

Description of Debt Securities

The debt securities covered by this prospectus will be our general senior unsecured obligations. We will issue the debt securities under the Indenture dated as of March 10, 2015 between us and U.S. Bank National Association, as trustee, which we refer to herein as the “indenture.” We have summarized selected provisions of the indenture and the debt securities below. This summary is not complete. For a complete description, we encourage you to read the indenture. We have filed the indenture with the SEC, 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. Please read “Where You Can Find More Information.”

In this summary description of the debt securities, unless we state otherwise or the context clearly indicates otherwise, all references to “we,” “us,” “our” or “Valero” are references to Valero Energy Corporation only.

Ranking

The debt securities will constitute senior debt and will rank equally with all of our unsecured and unsubordinated debt. The indenture does not limit the amount of debt securities that can be issued under the indenture or the amount of additional indebtedness we or any of our subsidiaries may incur. We may issue debt securities under the indenture from time to time in one or more series, each in an amount we authorize prior to issuance. The trustee will authenticate and deliver debt securities executed and delivered to it by us as set forth in the indenture.

We are organized as a holding company that owns subsidiary companies. Our subsidiary companies conduct substantially all of our business. The holding company structure results in two principal risks:

Terms

The prospectus supplement relating to any series of debt securities we are offering will include specific terms relating to that offering. These terms will include some or all of the following:

5

We may sell the debt securities at 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. We will describe in the prospectus supplement any material U.S. federal income tax consequences applicable to those securities.

If we sell any of the debt securities for any foreign currency or currency unit or if payments on the debt securities are payable in any foreign currency or currency unit, we will describe in the prospectus supplement the restrictions, elections, tax consequences, specific terms and other information relating to those debt securities and the foreign currency or currency unit.

Restrictive Covenants

We have agreed to two principal restrictions on our activities for the benefit of holders of the debt securities. Unless waived or amended, the restrictive covenants summarized below will apply to a series of debt securities issued under the indenture as long as any of those debt securities is outstanding, unless the prospectus supplement for the series states otherwise. We have used in this summary description terms that we have defined below under “— Glossary.”

Limitations on Liens

We have agreed that when any debt securities are outstanding neither we nor any of our Subsidiaries will create or assume any liens upon any of our receivables or other assets or any asset, stock or indebtedness of any

6

of our Subsidiaries unless those debt securities are secured equally and ratably with or prior to the debt secured by the lien. This covenant has exceptions that permit:

7

Limitations on Sale/Leaseback Transactions

We have agreed that neither we nor our Subsidiaries will enter into any sale/leaseback transactions with regard to any principal property, providing for the leasing back to us or a Subsidiary by a third party for a period of more than three years of any asset which has been or is to be sold or transferred by us or such Subsidiary to such third party or to any other person. This covenant has exceptions that permit transactions of this nature under the following circumstances:

In addition, we are permitted to enter into sale/leaseback transactions (i) with Valero Energy Partners GP LLC, Valero Energy Partners LP and their respective Subsidiaries and (ii) in an aggregate principal amount not exceeding, together with indebtedness secured by liens permitted by the last bullet discussed under the “Limitations on Liens” covenant described above, 10% of our consolidated net tangible assets.

Glossary

We define the following terms in the indenture. We use them here with the same definitions. Generally accepted accounting principles should be used to determine all items in this section, unless otherwise indicated.

“Consolidated net tangible assets” means the total amount of assets shown on a consolidated balance sheet of us and our Subsidiaries (excluding goodwill and other intangible assets), less all current liabilities (excluding notes payable, short-term debt and current portion of long-term debt and capital lease obligations).

“Funded debt” means generally any indebtedness for money borrowed, created, issued, incurred, assumed or guaranteed which would be classified as long-term debt or capital lease obligations.

“Principal Property” means any of our or our Subsidiaries’ refineries or refinery-related assets, distribution facilities or other real property that have a net book value exceeding 2.5% of consolidated net tangible assets, but not including any property which in our opinion is not material to our total business conducted as an entirety or any portion of a particular property that is similarly found not to be material to the use or operation of such property.

“Subsidiary” means any entity of which at the time of determination we or one or more of our Subsidiaries owns or controls directly or indirectly more than 50% of the shares of voting stock or the outstanding partnership or similar interests and any limited partnership (i) of which we or any one of our Subsidiaries are a general partner and (ii) which is consolidated with us for financial reporting purposes; provided that Valero Energy

8

Partners GP LLC and Valero Energy Partners LP and their respective Subsidiaries, for so long as Valero Energy Partners LP is not wholly owned, directly or indirectly, by us, in each case shall be deemed not to be Subsidiaries.

“wholly owned” means, when used with reference to an entity, an entity of which all of the outstanding capital stock (except for qualifying shares) or partnership or similar interests, as applicable, is owned by us or by one or more of our wholly owned Subsidiaries.

Consolidation, Merger and Sale

We have agreed in the indenture that we will consolidate with or merge into any entity or transfer or dispose of all or substantially all of our assets to any entity only if:

Events of Default

Unless we inform you otherwise in the prospectus supplement, the following are events of default under the indenture with respect to a series of debt securities issued under the indenture:

If an event of default for any series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the series affected by the default may declare the principal amount of all the debt securities of that series to be due and payable immediately. After any declaration of acceleration of a series of debt securities, but before a judgment or decree for payment has been obtained, the event of default giving rise to the declaration of acceleration will, without further act, be deemed to have been waived, and such declaration and its consequences will, without further act, be deemed to have been rescinded and annulled if:

9

In most cases, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders have offered to the trustee indemnity reasonably satisfactory to the trustee. Subject to this provision for indemnification and certain other limitations, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series may direct the time, method and place of:

The indenture requires us to furnish to the trustee annually a statement as to our performance of our obligations under the indenture and as to any default in performance.

Modification and Waiver

We may modify or amend the indenture without the consent of any holders of the debt securities in certain circumstances, including to:

We may modify or amend the indenture with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the modification or amendment. Without the consent of the holder of each outstanding debt security affected, however, no modification may:

The holders of a majority in aggregate principal amount of the outstanding debt securities of each series may waive past defaults by us under the indenture with respect to the debt securities of that series only. Those holders may not, however, waive any default in any payment on any debt security of that series or compliance with a provision that cannot be modified or amended without the consent of each holder affected.

10

Discharge

We will be discharged from all obligations relating to any series of debt securities, except for certain surviving obligations to register the transfer or exchange of the debt securities and any right by the holders to receive additional amounts under the indenture if:

To exercise the right of deposit described above, we must pay all other sums payable under the indenture, and deliver to the trustee an opinion of counsel and an officers’ certificate stating that all conditions precedent to the satisfaction and discharge of the indenture have been complied with.

Form, Exchange, Registration and Transfer

Unless we inform you otherwise in the prospectus supplement, we will issue the debt securities only in fully registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Debt securities will be exchangeable for other debt securities of the same series, the same total principal amount and the same terms in such authorized denominations as may be requested. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange when it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any transfer or exchange of the debt securities. We may, however, require payment of any tax or other governmental charge payable for the registration of the transfer or exchange.

We will appoint the trustee as security registrar for the debt securities. We are required to maintain an office or agency for transfers and exchanges in each place of payment. We may at any time designate additional offices or agencies for transfers and exchanges of any series of debt securities.

We will not be required:

Payment and Paying Agents

Unless we inform you otherwise in the prospectus supplement, principal and interest will be payable, and the debt securities will be transferable and exchangeable, at the office or offices of the trustee or any paying agent we designate. At our option, we will pay interest on the debt securities by check mailed to the holder’s registered address or by wire transfer for global debt securities. Unless we inform you otherwise in a prospectus supplement, we will make interest payments to the persons in whose name the debt securities are registered at the close of business on the record date for each interest payment date.

11

In most cases, the trustee and paying agent will repay to us upon written request any funds held by them for payments on the debt securities that remain unclaimed for two years after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment.

Book-Entry and Settlement

We may issue the debt securities of a series in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. The prospectus supplement will describe:

Notices

Notices to holders will be given by mail to the addresses of such holders as they appear in the security register.

Governing Law

New York law will govern the indenture and the debt securities.

The Trustee

U.S. Bank National Association is the trustee under the indenture.

If an event of default occurs and is continuing, the trustee will be required in the exercise of its rights and powers to use the degree of care and skill of a prudent person under the circumstances in the conduct of his own affairs. The trustee may resign at any time or the holders of a majority in principal amount of the debt securities may remove the trustee. If the trustee resigns, is removed or becomes incapable of acting as trustee or if a vacancy occurs in the office of the trustee for any reason, we will appoint a successor trustee in accordance with the provisions of the indenture.

If the trustee becomes one of our creditors, it will be subject to limitations in the indenture on its rights to obtain payment of claims or to realize on certain property received for any claim, as security or otherwise. The trustee may engage in other transactions with us. If, however, it acquires any conflicting interest, it must eliminate that conflict or resign as required under the Trust Indenture Act of 1939.

Plan of Distribution

We will set forth in the applicable prospectus supplement a description of the plan of distribution of the securities that may be offered pursuant to this prospectus.

Legal Matters

Mr. Jay D. Browning, Esq., our Executive Vice President and General Counsel, will issue opinions about the legality of the offered securities for us. Mr. Browning is our employee and at February 1, 2018, beneficially

12

owned approximately 218,512 shares of our common stock (including shares held under employee benefit plans) and held options under our employee stock option plans to purchase an additional 34,766 shares of our common stock. None of such shares or options were granted in connection with the offering of the securities. Any underwriters will be advised about issues relating to any offering by their own legal counsel.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth expenses payable by Valero in connection with the issuance and distribution of the securities being registered. All the amounts shown are estimates.

Valero Energy Corporation

Valero’s Restated Certificate of Incorporation, as amended (the “Restated Certificate of Incorporation”), contains a provision that eliminates the personal liability of a director to Valero and its stockholders for monetary damages for breach of fiduciary duty as a director to the extent currently allowed under the Delaware General Corporation Law. If a director were to breach such duty in performing duties as a director, neither Valero nor its stockholders could recover monetary damages from the director, and the only course of action available to Valero’s stockholders would be equitable remedies, such as an action to enjoin or rescind a transaction involving a breach of fiduciary duty. To the extent certain claims against directors are limited to equitable remedies, the provision in Valero’s Restated Certificate of Incorporation may reduce the likelihood of derivative litigation and may discourage stockholders or management from initiating litigation against directors for breach of their fiduciary duties. Additionally, equitable remedies may not be effective in many situations. If a stockholder’s only remedy is to enjoin the completion of the Board of Directors’ action, this remedy would be ineffective if the stockholder does not become aware of a transaction or event until after it has been completed. In such a situation, it is possible that the stockholders and Valero would have no effective remedy against the directors. Under Valero’s Restated Certificate of Incorporation, liability for monetary damages remains for (i) any breach of the duty of loyalty to Valero or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) payment of an improper dividend or improper repurchase or redemption of Valero’s stock under Section 174 of the Delaware General Corporation Law, or (iv) any transaction from which the director derived an improper personal benefit.

Under Article V of the Restated Certificate of Incorporation and Article VIII of Valero’s Amended and Restated By-laws as currently in effect (the “Restated By-laws”) and an indemnification agreement with Valero’s officers and directors (the “Indemnification Agreement”), each person who is or was a director or officer of Valero or a subsidiary of Valero, or who serves or served any other enterprise or organization at the request of

II-1

Valero or a subsidiary of Valero (collectively, an “Indemnitee”), shall be indemnified by Valero to the full extent permitted by the Delaware General Corporation Law.

Under such law, to the extent that an Indemnitee is successful on the merits in defense of a suit or proceeding brought against the Indemnitee by reason of the fact that he or she is or was a director or officer of Valero, or serves or served any other enterprise or organization at the request of Valero, the Indemnitee shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred in connection with such action.

Under such law, if unsuccessful in defense of a third-party civil suit or a criminal suit, or if such suit is settled, the Indemnitee shall be indemnified against both (a) expenses, including attorneys’ fees, and (b) judgments, fines and amounts paid in settlement if he or she acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of Valero, and, with respect to any criminal action, had no reasonable cause to believe his conduct was unlawful.

If unsuccessful in defense of a suit brought by or in the right of Valero, or if such a suit is settled, the Indemnitee shall be indemnified under such law only against expenses (including attorneys’ fees) actually and reasonably incurred in the defense or settlement of such suit if he or she acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interests of Valero, except that if the Indemnitee is adjudged to be liable in such a suit for negligence or misconduct in the performance of duties to Valero, the Indemnitee cannot be made whole for expenses unless the court determines that he or she is fairly and reasonably entitled to indemnity for such expenses.

The Indemnification Agreement provides directors and officers with specific contractual assurance that indemnification and advancement of expenses will be available to them regardless of any amendments to or revocation of the indemnification provisions of Valero’s Restated By-laws. The Indemnification Agreement provides for indemnification of directors and officers against both stockholder derivative claims and third-party claims. Sections 145(a) and 145(b) of the Delaware General Corporation Law, which grant corporations the power to indemnify directors and officers, specifically authorize lesser indemnification in connection with derivative claims than in connection with third-party claims. The distinction is that Section 145(a), concerning third-party claims, authorizes expenses and judgments and amounts paid in settlement (as is provided in the Indemnification Agreement), while Section 145(b), concerning derivative suits, generally authorizes only indemnification of expenses. However, Section 145(f) expressly provides that the indemnification and advancement of expenses provided by or granted pursuant to the subsections of Section 145 shall not be exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any agreement. Delaware case law does not directly answer whether Delaware’s public policy would support this aspect of the Indemnification Agreement under the authority of Section 145(f), or would cause its invalidation because it does not conform to the distinctions contained in Sections 145(a) and 145(b).

Delaware corporations also are authorized to obtain insurance to protect officers and directors from certain liabilities, including liabilities against which the corporation cannot indemnify its directors and officers. Valero currently has in effect a directors’ and officers’ liability insurance policy.

(a) The undersigned Registrant hereby undertakes:

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

(i) 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) 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 (1)(i), (1)(ii) and (1)(iii) 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 the 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) 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.

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

(A) 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

(B) 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 the undersigned Registrant pursuant to the 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, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

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

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

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

(iv) Any other communication that is an offer in the offering made by the 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 the 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, the 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.

(d) The undersigned Registrant hereby undertakes to file an application for the purposes of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939 in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act of 1939.
