$450,000,000 of 5.650% Senior Notes due 2052

Albemarle Corporation (“Albemarle”) is offering $650,000,000 aggregate principal amount of its 4.650% Senior Notes due 2027 (the “2027 notes”), $600,000,000 aggregate principal amount of its 5.050% Senior Notes due 2032 (the “2032 notes”) and $450,000,000 aggregate principal amount of its 5.650% Senior Notes due 2052 (the “2052 notes” and, together with the 2027 notes and the 2032 notes, the “notes”). The 2027 notes, the 2032 notes and the 2052 notes will mature on June 1, 2027, June 1, 2032 and June 1, 2052, respectively. Interest on the notes will be payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2022.

We intend to use a portion of the net proceeds from this offering to fund a redemption of our outstanding 4.15% Senior Notes due 2024 (the “2024 Notes”), including the payment of the associated redemption premium. We intend to use the remaining net proceeds of this offering for general corporate purposes, including the repayment of outstanding commercial paper notes. See “Use of Proceeds.”

We may redeem the notes in whole or in part at any time at the redemption prices described in this prospectus supplement under the heading “Description of Notes—Optional Redemption.” Upon the occurrence of a Change of Control Triggering Event (as defined herein), each holder of notes will have the right to require us to purchase all or a portion of such holder’s notes at a price equal to 101% of their aggregate principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase, as further described in this prospectus supplement under the heading “Description of Notes—Offer to Repurchase Upon Change of Control Triggering Event.”

The notes will be our general senior unsecured obligations and will rank equally in right of payment with all of our existing and future senior unsecured indebtedness and other obligations that are not, by their terms, expressly subordinated in right of payment to the notes. The notes will be structurally subordinated to all liabilities, including trade payables, of our subsidiaries. None of our subsidiaries will guarantee the notes.

The notes will not be listed on any securities exchange or automated quotation system. Currently there are no public markets for the notes and we cannot provide any assurances that an active public market for the notes will develop.

Investing in the notes involves certain risks. Please read “Risk Factors” beginning on page S-8 of this prospectus supplement and on page 1 of the accompanying prospectus and any risk factors described in the documents we incorporate by reference for information about important factors you should consider before buying the notes.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these notes or passed upon the adequacy or accuracy of this prospectus supplement or the accompanying prospectus. Any representation to the contrary is a criminal offense.

The notes will not be listed on any securities exchange or automated quotation system.

FORWARD-LOOKING STATEMENTS

Some of the information presented in this prospectus supplement, the accompanying prospectus, and any document incorporated by reference and any related free writing prospectus, may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are based on our current expectations, which are in turn based on assumptions that we believe are reasonable based on our current knowledge of our business and operations. We have used words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “should,” “would,” “will” and variations of such words and similar expressions to identify such forward-looking statements. All statements other than statements of historical facts are forward-looking statements.

These forward-looking statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict and many of which are beyond our control. There can be no assurance that our actual results will not differ materially from the results and expectations expressed or implied in the forward-looking statements. Factors that could cause actual results to differ materially from the outlook expressed or implied in any forward-looking statement include, without limitation, information related to:

S-iii

The forward-looking statements included in this prospectus supplement speak only as of the date of this document. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements. Except as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consider any additional disclosures that we may make on related subjects in future filings with the SEC. You should consider the areas of risk described above, as well as those set forth under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, as amended by Amendment No. 1 thereto filed on March 2, 2022, those identified under the heading “Risk Factors” beginning on page S-8 of this prospectus supplement, as well as in our periodic reports on file from time to time in connection with considering any forward-looking statements that may be made by us and our businesses generally. You should understand that it is not possible to predict or identify all factors that could cause our actual results to differ. Consequently, you should not consider any list of factors to be a complete set of all potential risks or uncertainties.

RISK FACTORS

You should carefully consider the following factors and those described in our Annual Report on Form 10-K for our fiscal year ended December 31, 2021 and any of our subsequently filed Quarterly Reports on Form 10-Q, as well as the other information contained or incorporated by reference in this prospectus supplement, before deciding to invest in the notes. Any of these risks or other risks and uncertainties not presently known to us or that we currently deem immaterial could materially adversely affect our business, financial condition, results of operations and cash flow, which could in turn materially adversely affect the price of the notes. If any of the following risks and uncertainties develop into actual events, our business, financial condition, results of operations or cash flows could be materially adversely affected. In that case, the trading price of the notes could decline and you may lose all or part of your investment.

This prospectus supplement also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of the risks faced by us described below and elsewhere in this prospectus supplement and the documents incorporated by reference. Please see “Forward-Looking Statements.”

Risks Relating to the Notes and this Offering

Because a significant portion of Albemarle’s operations is conducted through its subsidiaries and joint ventures, Albemarle’s ability to service its debt could be dependent on its receipt of distributions or other payments from its subsidiaries and joint ventures.

A significant portion of Albemarle’s operations is conducted through its subsidiaries and joint ventures. As a result, Albemarle’s ability to service its debt could be dependent on the earnings of our subsidiaries and joint ventures and the payment of those earnings to us in the form of dividends, loans or advances and through repayment of loans or advances from Albemarle. Payments to Albemarle by its subsidiaries and joint ventures will be contingent upon our subsidiaries’ or joint ventures’ earnings and other business considerations and may be subject to statutory or contractual restrictions. In addition, there may be significant tax and other legal restrictions on the ability of non-U.S. subsidiaries or joint ventures to remit money to Albemarle.

The notes will be structurally subordinated to all liabilities of our subsidiaries.

The notes will not be guaranteed by any of our subsidiaries and are, therefore, structurally subordinated to the indebtedness and other liabilities of our subsidiaries. These subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Our subsidiaries represented approximately 85% of our total assets and approximately 61% of our total liabilities as of March 31, 2022, including intercompany activity. In addition, for the fiscal year ended December 31, 2021 and the three months ended March 31, 2022, our subsidiaries generated approximately 76% of our net sales in each period and 140% and 146% of our net income, respectively, which percentages include intercompany activity. The indenture does not limit our ability or the ability of our subsidiaries to incur additional indebtedness. As of March 31, 2022, on an as adjusted basis after giving effect to the offering of the notes and the application of the proceeds therefrom, we would have had total long-term debt of approximately $3.5 billion, consisting of, among other things, $350.0 million aggregate principal amount of our 5.45% senior notes due 2044, $171.6 million aggregate principal amount of 3.45% senior notes due 2029 issued by Albemarle Wodgina Pty Ltd (“Wodgina”), our wholly owned subsidiary, €500.0 million aggregate principal amount of 1.625% senior notes issued by Albemarle New Holding GmbH, our wholly owned subsidiary (“New Holding”), due 2028, €371.7 million aggregate principal amount of New Holding’s 1.125% senior notes due 2025, and $1.7 billion aggregate principal amount of our notes offered hereby. Any right that we have to receive any assets of any of the subsidiaries upon the liquidation or reorganization of those subsidiaries, and the consequent rights of holders of notes to realize

S-8

proceeds from the sale of any of those subsidiaries’ assets, will be effectively subordinated to the claims of those subsidiaries’ creditors, including trade creditors and holders of preferred equity interests of those subsidiaries. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, these subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us.

The terms of the indenture and the notes provide only limited protection against significant corporate events and other actions we may take that could adversely impact your investment in the notes.

While the indenture and the notes contain terms intended to provide protection to the holders of the notes upon the occurrence of certain events involving significant corporate transactions, such terms are limited and may not be sufficient to protect your investment in the notes.

The definition of the term “Change of Control Triggering Event” (as defined in “Description of Notes—Offer to Repurchase Upon Change of Control Triggering Event”) does not cover a variety of transactions (such as acquisitions by us or recapitalizations) that could negatively affect the value of your notes. If we were to enter into a significant corporate transaction that would negatively affect the value of the notes but would not constitute a Change of Control Triggering Event, we would not be required to offer to repurchase your notes prior to their maturity.

Furthermore, the indenture for the notes does not:

As a result of the foregoing, when evaluating the terms of the notes, you should be aware that the terms of the indenture and the notes do not restrict our ability to engage in, or to otherwise be a party to, a variety of corporate transactions, circumstances and events that could have an adverse impact on your investment in the notes.

Revisions downward or withdrawals entirely of credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing, the market price of our securities and our debt service obligations.

Credit rating agencies rate our debt securities on factors that include our operating results, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading or downgrading the current rating or placing us on a watch list for possible future downgrades. Ratings only reflect the views of the issuing rating agency or agencies and such ratings could at any time be revised downward or withdrawn entirely at the discretion of the issuing rating agency. A rating is not a recommendation to purchase, sell or hold the notes. Ratings do not reflect market prices or suitability of a security for a particular investor and the rating of the notes may not reflect all risks related to us and our business, or the structure or market value of the notes. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrades would likely increase our cost of future financing, limit our access to the capital markets and have an adverse effect on the market price of our securities.

S-9

Borrowings under a portion of our debt facilities bear interest at floating rates, and are subject to adjustment based on the ratings of our senior unsecured long-term debt. The downgrading of any of our ratings or an increase in any of the benchmark interest rates would result in an increase of the interest expense on our variable rate borrowings. We may also elect to issue other securities for which we may seek to obtain a rating in the future. If we issue other securities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the notes.

The instruments governing our indebtedness do not limit our acquisitions and allow us to incur additional indebtedness, including indebtedness in relation to acquisitions.

We have historically expanded our business primarily through acquisitions. A part of our business strategy is to continue to grow through acquisitions that complement our existing technologies and accelerate our growth. Our credit facilities have limited financial maintenance covenants. In addition, the indenture and other agreements governing our senior notes do not limit our ability to incur additional indebtedness in connection with acquisitions or otherwise. As a result, we may incur substantial additional indebtedness in connection with acquisitions. Because the consummation of acquisitions and integration of acquired businesses involves significant risk, this means that holders of the notes will be subject to the risks inherent in our acquisitive strategy.

In addition, the indenture governing the notes described in this prospectus supplement does not restrict our ability to incur additional unsecured indebtedness, which may rank equally with the notes, and subject to some limitations, permits us to incur secured indebtedness.

We may not have sufficient funds to purchase notes upon a Change of Control Triggering Event.

If there is a Change of Control Triggering Event under the terms of the indenture governing the notes, each holder of notes may require us to purchase all or a portion of their notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, up to but not including the date of purchase. In order to purchase any outstanding notes, we might have to refinance our outstanding indebtedness, which we might not be able to do. Even if we were able to refinance our other indebtedness, any financing might be on terms unfavorable to us. In addition, our Revolving Credit Facility (as defined below) provides that the occurrence of certain kinds of change of control events will constitute a default under our Revolving Credit Facility. We cannot assure you that we will have the financial ability to purchase outstanding notes upon the occurrence of a change of control. See “Description of Notes—Offer to Repurchase Upon Change of Control Triggering Event.”

You may not be able to determine when a Change of Control Trigger Event has occurred.

Unless we have exercised our right to redeem the notes, a Change of Control Triger Event, as defined in the indenture governing the notes, will require us to make an offer to repurchase all outstanding notes. The definition of change of control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our assets and the assets of our subsidiaries taken as a whole. There is no precisely established definition of the phrase “substantially all” under applicable law. Accordingly, your ability to require us to repurchase your notes as a result of a direct or indirect sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another individual, group or entity may be uncertain. See “Description of Notes — Offer to Repurchase Upon Change of Control Triggering Event.”

Some significant transactions may not constitute a Change of Control Trigger Event for purposes of the notes in which case we would not be obligated to offer to repurchase the notes.

Upon the occurrence of a Change of Control Trigger Event as described under “Description of Notes — Offer to Repurchase Upon Change of Control Triggering Event,” we will be required to offer to repurchase the

S-10

notes. However, the change of control trigger event provisions will not afford protection to holders of notes in the event of certain transactions. For example, any leveraged recapitalization, refinancing, restructuring or acquisition initiated by us will generally not constitute a change of control trigger event requiring us to repurchase the notes. In the event of any such transaction, we will not be required to offer to repurchase the notes, even though any of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or credit ratings, thereby adversely affecting the holders of notes, including by decreasing the trading prices for the notes.

We have broad discretion in the use of the net proceeds of this offering and may not use them effectively.

We intend to use a portion of the net proceeds from this offering to fund a redemption of the 2024 Notes, including the payment of the associated redemption premium. We intend to use the remaining net proceeds of this offering for general corporate purposes, including the repayment of outstanding commercial paper notes. However, our management will have broad discretion in the application of the net proceeds from this offering after the redemption of the 2024 Notes and could spend the proceeds in ways that do not improve our results of operations. The failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, financial condition, results of operations and cash flow and cause the price of the notes to decline.

The notes will be unsecured and therefore will be effectively subordinated to any secured indebtedness that we may incur in the future.

The notes will not be secured by any of our assets or any of the assets of our subsidiaries. As a result, the notes will be effectively subordinated to any secured indebtedness that we or our subsidiaries may incur in the future to the extent of the value of the assets securing such indebtedness. As of December 31, 2021, we had approximately $2.0 billion of indebtedness outstanding. The indenture governing the notes will not prohibit us or our subsidiaries from incurring additional secured (or unsecured) indebtedness in the future. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our future secured indebtedness and any future secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness and may consequently receive payment from these assets before they may be used to pay other creditors, including the holders of the notes.

There may be no active trading market for the notes.

Each series of the notes is a new issue of securities for which there is no established market. Accordingly, any or all of the following may occur:

If a public market were to exist, the notes could trade at prices that may be higher or lower than their principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar notes, the then-current ratings assigned to the notes and our financial performance. We do not intend to list the notes on any securities exchange or to seek approval for quotations through any automated quotation system. No active market for the notes is currently anticipated.

An increase in market interest rates could result in a decrease in the value of the notes.

In general, as market interest rates rise, notes bearing interest at a fixed rate decline in value. Consequently, if you purchase the notes, and the market interest rates subsequently increase, the market value of your notes may decline.

S-11

Redemption may adversely affect your return on the notes.

We have the right to redeem the notes prior to maturity, as described under “Description of Notes — Optional Redemption” in this prospectus supplement. We may redeem the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate of the notes being redeemed.

Risks Relating to Our Indebtedness

We will need a significant amount of cash to service our indebtedness and our ability to generate cash depends on many factors beyond our control.

Our ability to generate sufficient cash flow from operations or use existing cash balances to make scheduled payments on our debt depends on a range of economic, competitive and business factors, many of which are outside our control. Our business may not generate sufficient cash flow from operations to service our debt obligations. If we are unable to service our debt obligations, we may need to refinance all or a portion of our indebtedness on or before maturity, reduce or delay capital expenditures, sell assets or raise additional equity. We may not be able to refinance any of our indebtedness, sell assets or raise additional equity on commercially reasonable terms or at all, which could cause us to default on our obligations and impair our liquidity. Our inability to generate sufficient cash flow or use existing cash balances to satisfy our debt obligations, or to refinance our obligations on commercially reasonable terms, could have a material adverse effect on our business and financial condition.

Restrictive covenants in our debt instruments may adversely affect our business.

Our senior credit facilities and the indentures governing our senior notes contain select restrictive covenants. These covenants provide constraints on our financial flexibility. The failure to comply with these or other covenants governing other indebtedness, including indebtedness incurred in the future, could result in an event of default, which, if not cured or waived, could have a material adverse effect on our business, financial condition, results of operations and cash flow, including cross-defaults to other debt facilities.

Because a significant portion of our operations is conducted through our subsidiaries and joint ventures, our ability to service our debt may be dependent on our receipt of distributions or other payments from our subsidiaries and joint ventures.

A significant portion of our operations is conducted through our subsidiaries and joint ventures. As a result, our ability to service our debt may be partially dependent on the earnings of our subsidiaries and joint ventures and the payment of those earnings to us in the form of dividends, loans or advances and through repayment of loans or advances from us. Payments to us by our subsidiaries and joint ventures are contingent upon our subsidiaries’ or joint ventures’ earnings and other business considerations and may be subject to statutory or contractual restrictions. In addition, there may be significant tax and other legal restrictions on the ability of our non-U.S. subsidiaries or joint ventures to remit money to us.

S-12

USE OF PROCEEDS

We estimate that the net proceeds from this offering, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us, will be approximately $1.680 billion. We intend to use approximately $436 million of the net proceeds from this offering to fund a redemption of the outstanding 2024 Notes, which were issued in 2014 and of which $425.0 million aggregate principal amount is outstanding as of the date of this prospectus supplement, in accordance with the terms of the indenture governing the 2024 Notes. This prospectus supplement is not a notice of redemption with respect to the 2024 Notes.

The 2024 Notes mature on December 1, 2024. Interest on the 2024 Notes accrues at a stated rate of 4.150%, subject to adjustment in the event of changes in our credit ratings that were in effect when the 2024 Notes were issued, payable semi-annually on December 1 and June 1 of each year. As of the date of this prospectus supplement, interest accrues on the 2024 Notes at a rate of 4.150%. We expect to pay a redemption premium of approximately $11 million, subject to changes in market rates, in connection with our intended redemption of the outstanding 2024 Notes. To the extent any of the underwriters or their affiliates own any of the 2024 Notes, upon application of the net proceeds of this offering to redeem the outstanding the 2024 Notes, such underwriters or affiliates would receive a portion of the net proceeds of this offering. See “Underwriting”.

Any net proceeds from this offering that are not used to fund a redemption of the outstanding 2024 Notes will be used for general corporate purposes, including the repayment of outstanding commercial paper notes. To the extent any of the underwriters or their affiliates are agents, holders, lenders and/or counterparties under or to any of the Company’s commercial paper or other indebtedness that may be repaid with a portion of the net proceeds of this offering, such underwriters or affiliates would receive a portion of the net proceeds of this offering. See “Underwriting”.

Until the net proceeds from this offering are applied as described above, we may invest such net proceeds in short-term, investment grade interest-bearing securities or in obligations of, or guaranteed by, the U.S. government.

CAPITALIZATION

The following table sets forth, as of March 31, 2022, our consolidated capitalization and cash and cash equivalents:

Actual amounts may vary from the as-adjusted amounts set forth below depending on several factors, including potential changes in our financing plans as a result of market conditions. You should read the data set forth in the table below in conjunction with “Use of Proceeds” and “Risk Factors” included in this prospectus supplement and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes incorporated by reference in this prospectus supplement and the accompanying prospectus, as well as any related free writing prospectus.

DESCRIPTION OF NOTES

The following description is a summary of the terms of the notes being offered. The descriptions in this prospectus supplement and the accompanying prospectus contain descriptions of certain terms of the notes and the indenture but do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the indenture which has been filed as an exhibit to the registration statement of which this prospectus supplement and the accompanying prospectus are a part, including the definitions of specified terms used in the indenture, and to the Trust Indenture Act of 1939, as amended. Wherever particular articles, sections or defined terms of the indenture are referred to, it is intended that those articles, sections or defined terms will be incorporated herein by reference, and the statement in connection with which reference is made is qualified in its entirety by the article, section or defined term in the indenture. This summary supplements the description of the debt securities in the accompanying prospectus and, to the extent it is inconsistent, replaces the description in the accompanying prospectus. Capitalized terms used but not defined in this prospectus supplement have the meanings ascribed to those terms in the accompanying prospectus. When we refer to “Albemarle,” “the Company,” “we, “our,” or “us” in this section, we refer only to Albemarle Corporation and not its subsidiaries.

General

The notes will be issued under the indenture dated as of January 20, 2005, between us and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as successor to The Bank of New York Mellon Trust Company, N.A. (formerly The Bank of New York), as trustee, as amended and supplemented from time to time. The 2027 senior notes will be initially issued in an aggregate principal amount of $650,000,000 and will mature on June 1, 2027. The 2032 senior notes will be initially issued in an aggregate principal amount of $600,000,000 and will mature on June 1, 2032. The 2052 senior notes will be initially issued in an aggregate principal amount of $450,000,000 and will mature on June 1, 2052. The 2027 senior notes, the 2032 senior notes and 2052 senior notes are collectively referred to herein as the “notes.” The notes will be direct unsecured obligations of the Company.

The notes will bear interest at the applicable rate per annum shown on the cover of this prospectus supplement from May 13, 2022, or from the most recent date to which interest has been paid or provided for, payable semi-annually on June 1 and December 1, commencing December 1, 2022 to the persons in whose names the notes are registered at the close of business on the next preceding May 15 or November 15, respectively.

The indenture does not limit our ability or the ability of our subsidiaries to incur additional indebtedness. As of March 31, 2022, on an as adjusted basis after giving effect to the offering of the notes and the application of the proceeds therefrom, Albemarle would have had total long-term debt of approximately $3.5 billion, consisting of, among other things, $350.0 million aggregate principal amount of the Company’s 5.45% senior notes due 2044, $171.6 million aggregate principal amount of 3.45% senior notes due 2029 issued by Wodgina, a wholly owned subsidiary of the Company, €500.0 million aggregate principal amount of 1.625% senior notes issued by New Holding, a wholly owned subsidiary of the Company, due 2028, €371.7 million aggregate principal amount of New Holding’s 1.125% senior notes due 2025, and $1.7 billion aggregate principal amount of the Company’s notes offered hereby.

We may from time to time without notice to, or the consent of, the holders of the notes, create and issue additional notes of any of such series under the indenture, equal in rank to the notes of such series in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new notes, or except under certain circumstances for the first payment of interest following the issue date of the new notes) so that the new notes may be consolidated and form a single series with the notes and have the same terms as to status, redemption and otherwise as the notes of such series issued under this prospectus supplement; provided that if such additional notes are not fungible with such series of notes for U.S. federal income tax purposes, such additional notes shall be issued with a separate CUSIP number.

S-15

The notes will be issued only in fully registered form in minimum denominations of $2,000 and multiples of $1,000 in excess thereof.

Ranking

The notes will be:

Payments on the Notes

Payments of the principal and premium, if any, in respect of notes that are not global securities will be made upon the surrender of the notes at the office or agency of the Company maintained for that purpose in the United States designated from time to time by the trustee and payments of interest will be made by check mailed to holders at their addresses set forth in the security register; provided, however, that payments of interest will be made by wire transfer if a holder of at least $1.0 million in principal amount of notes has given wire transfer instructions to the trustee at least five business days prior to the applicable interest payment date. All payments of notes that are represented by global securities will be made by the transfer of immediately available funds to the nominee of the depositary for the notes of such series.

Optional Redemption

Prior to May 1, 2027 (one month prior to their maturity date, the “2027 Par Call Date”), in the case of the 2027 senior notes, March 1, 2032 (three months prior to their maturity date, the “2032 Par Call Date”), in the case of the 2032 senior notes, and December 1, 2051 (six months prior to their maturity date, the “2052 Par Call Date” and, together with the 2027 Par Call Date and the 2032 Par Call Date, the “Par Call Dates” and each a “Par Call Date”) in the case of the 2052 senior notes, we may redeem the notes of the applicable series at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points in the case of the 2027 senior notes, 35 basis points in the case of the 2032 senior notes and 40 basis points in the case of the 2052 senior notes less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the applicable Par Call Date, the Company may redeem the notes of the applicable series, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

S-16

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date, H.15 or any successor designation or publication is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, we shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes of the applicable series to be redeemed.

In the case of a partial redemption, selection of the notes of the applicable series for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by the Depository Trust Company (“DTC”) (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

S-17

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof of the applicable series called for redemption.

Offer to Repurchase Upon Change of Control Triggering Event

Upon the occurrence of a Change of Control Triggering Event with respect to the notes, unless we have exercised our right to redeem the notes as described under “Description of the Notes—Optional Redemption” by giving irrevocable notice to the trustee and the holders in accordance with the indenture, each holder of notes will have the right to require us to purchase all or a portion of such holder’s notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, up to but not including the date of purchase (the “Change of Control Payment”).

Unless we have exercised our right to redeem the notes, within 30 days following the date upon which the Change of Control Triggering Event occurs or, at our option, prior to any Change of Control but after the public announcement of the pending Change of Control, we will be required to send a notice to each holder of notes to their addresses as set forth in the register, with a copy to the trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the “Change of Control Payment Date”). The notice, if sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, we will, to the extent lawful:

We will not be required to make a Change of Control Offer with respect to the notes if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by us and such third party purchases all the notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the indenture, other than a default in the payment of the Change of Control Payment on the Change of Control Payment Date.

We must comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will be required to comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

For purposes of the foregoing discussion of a Change of Control Offer, the following definitions are applicable:

“Change of Control” means the occurrence of any of the following after the date of issuance of the notes:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our assets and the assets of

S-18

our subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to us or one of our subsidiaries;

(2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than us or one of our subsidiaries) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of our Voting Stock representing a majority of the voting power of our outstanding Voting Stock;

(3) we consolidate with, or merge with or into, any Person, or any Person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding Voting Stock or Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where our Voting Stock outstanding immediately prior to such transaction constitutes, or is converted into or exchanged for, Voting Stock representing a majority of the voting power of the Voting Stock of the surviving Person immediately after giving effect to such transaction; or

(4) the adoption by our stockholders of a plan relating to our liquidation or dissolution.

Notwithstanding the foregoing, a transaction (or series of related transactions) will not be deemed to involve a Change of Control under clause (2) above if (i) we become a direct or indirect wholly-owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (as that term is used in Section 13(d)(3) of the Exchange Act) (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Change of Control Triggering Event” means, with respect to a series of notes, (i) the rating of such series of notes is lowered by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing on the earlier of (a) the occurrence of a Change of Control and (b) the first public announcement by us of any Change of Control (or pending Change of Control), and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change), and (ii) such series of notes are rated below Investment Grade by each of the Rating Agencies on any day during the Trigger Period; provided that a Change of Control Triggering Event will not be deemed to have occurred in respect of a particular Change of Control if each Rating Agency making the reduction in rating does not publicly announce or confirm or inform the trustee at our or its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control.

Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P), and the equivalent investment grade credit rating from any replacement rating agency or rating agencies selected by us under the circumstances permitting us to select a replacement rating agency and in the manner for selecting a replacement rating agency, in each case as set forth in the definition of “Rating Agency.”

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

S-19

“Person” means any individual, corporation, partnership, limited liability company, business trust, association, joint-stock company, joint venture, trust, incorporated or unincorporated organization or government or any agency or political subdivision thereof.

“Rating Agency” means each of Moody’s and S&P; provided, that if either Moody’s or S&P ceases to provide rating services to issuers or investors, we may appoint another “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act as a replacement for such Rating Agency; provided that we shall give notice of such appointment to the trustee.

“S&P” means Standard & Poor’s Financial Services LLC, a division of S&P Global Inc., and its successors.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our assets and the assets of our subsidiaries taken as a whole. 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, the applicability of the requirement that we offer to repurchase the notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) may be uncertain.

Sinking Fund

There is no provision for a sinking fund applicable to the notes.

Events of Default

You will have special rights if an event of default occurs with respect to the notes and such event of default is not cured, as described under “Description of Debt Securities—Default and Related Matters” in the accompanying prospectus.

Defeasance

The notes will be subject to the defeasance provisions described under the caption “Description of Debt Securities—Defeasance” in the accompanying prospectus.

Security Register

The security register for the notes will be maintained at an office or agency of the trustee in the United States.

Book-Entry System

Each series of the notes initially will be represented by one or more registered global securities (the “Registered Global Securities”) registered in the name of Cede & Co. (the nominee of DTC), or such other name as may be requested by an authorized representative of DTC. The provisions set forth under “Description of Debt Securities—Legal Ownership” in the accompanying prospectus will be applicable to the notes. Accordingly, beneficial interests in the notes will be shown on, and transfers of the notes will be effected only through, records maintained by DTC and its participants. Except as described under “Description of Debt Securities—Legal Ownership” in the accompanying prospectus, owners of beneficial interests in the Registered Global Securities representing the notes will not be entitled to receive notes in definitive form and will not be considered holders of notes under the indenture.

S-20

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The DTC Rules applicable to its participants are on file with the SEC.

Purchases of notes under DTC’s system must be made by or through participants (for example, your broker), which will receive a credit for such notes on DTC’s records. The ownership interest of each actual purchaser of notes represented by the Registered Global Securities (“Beneficial Owner”) is in turn to be recorded on the participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through which such Beneficial Owners entered into the transaction. Transfers of ownership interests in the Registered Global Securities representing notes are to be accomplished by entries made on the books of participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive notes in definitive form, except in the event that use of the book-entry system for such notes is discontinued or upon the occurrence of certain other events described in the accompanying prospectus and in this prospectus supplement.

To facilitate subsequent transfers, the Registered Global Securities representing notes that are deposited by direct participants are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the Registered Global Securities with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Registered Global Securities representing the notes; DTC’s records reflect only the identity of the participants to whose accounts such notes are credited, which may or may not be the Beneficial Owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to participants and by participants and to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. (or any other Depository nominee) will consent or vote with respect to the Registered Global Securities representing the notes. Under its usual procedures, DTC mails an omnibus proxy to Albemarle as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the notes are credited on the applicable record date (identified in a listing attached to the omnibus proxy).

Proceeds, distributions or other payments on the debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit participants’ accounts upon DTC’s receipt of funds in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants and not DTC, the trustee or Albemarle, subject to any statutory or

S-21

regulatory requirements as may be in effect from time to time. Neither Albemarle nor the trustee will have any responsibility or liability for the disbursements of payments in respect of ownership interests in the notes by DTC or the participants or for maintaining or reviewing any records of DTC or the participants relating to ownership interests in the notes or the disbursement of payments in respect of the notes.

DTC may discontinue providing its services as securities depository with respect to the notes at any time by giving reasonable notice to Albemarle or the trustee. Under such circumstances, and in the event that a successor securities depository is not obtained, notes in definitive form are required to be printed and delivered to each holder.

We may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). In that event, notes in definitive form will be printed and delivered.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

DESCRIPTION OF OTHER INDEBTEDNESS

Outstanding Notes

On November 24, 2014, the Company issued $425.0 million aggregate principal amount of 4.15% senior notes due 2024 and $350.0 million aggregate principal amount of 5.45% senior notes due 2044 (together the “2014 Senior Notes”). The 2014 Senior Notes are guaranteed by New Holding pursuant to the Sixth Supplemental Indenture, dated as of March 30, 2021.

On November 1, 2019, Wodgina issued $300.0 million aggregate principal amount of 3.45% senior notes due 2029 (the “Wodgina Senior Notes”). The Wodgina Senior Notes are fully and unconditionally guaranteed on a senior unsecured basis by the Company. No direct or indirect subsidiaries of the Company guarantee the Wodgina Senior Notes.

On November 25, 2019, New Holding issued and sold outside the United States pursuant to Regulation S under the Securities Act of 1933, (i) €500,000,000 aggregate principal amount of 1.125% Notes due 2025 and (ii) €500,000,000 aggregate principal amount of 1.625% Notes due 2028 (together, the “Euro Notes”). The Euro Notes are fully and unconditionally guaranteed on a senior unsecured basis by the Company.

In March 2021, New Holding added a full and unconditional guarantee to all securities issued and outstanding by the Company and issuable by the Company pursuant to the Indenture, dated as of January 20, 2005, as amended and supplemented from time to time. No other direct or indirect subsidiaries of the Company guarantee these securities.

As of March 31, 2022, we had the following notes outstanding:

The Wodgina Senior Notes and the 2014 Senior Notes (together, the “Senior Notes”) are senior unsecured obligations and rank equally with all our other senior unsecured indebtedness from time to time outstanding. The Senior Notes are effectively subordinated to all of our existing or future secured indebtedness and to the existing and future indebtedness of our subsidiaries. As is customary for such long-term debt instruments, each series of notes outstanding has terms that allow us to redeem the notes before maturity, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of these notes to be redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis using the comparable government rate (as defined in the indentures governing these notes) plus between 25 and 40 basis points, depending on the series of notes, plus, in each case, accrued interest thereon to the date of redemption. Holders may require us to purchase such notes at 101% upon a change of control triggering event, as defined in the indentures. The Senior Notes are subject to typical events of default, including bankruptcy and insolvency events, nonpayment and the acceleration of certain subsidiary indebtedness of $40 million or more caused by a nonpayment default.

The Euro Notes are unsecured and unsubordinated obligations and rank equally in right of payment to all our other unsecured senior obligations. The Euro Notes are effectively subordinated to all of our existing or

S-23

future secured indebtedness and to the existing and future indebtedness of our subsidiaries. As is customary for such long-term debt instruments, each series of notes outstanding has terms that allow us to redeem the notes before their maturity, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal thereof and interest thereon (exclusive of interest accrued to, but excluding, the date of redemption) discounted to the redemption date on an annual basis using the bond rate (as defined in the indentures governing these notes) plus between 25 and 35 basis points, depending on the series of notes, plus, in each case, accrued and unpaid interest on the principal amount being redeemed to, but excluding, the date of redemption. Holders may require us to purchase such notes at 101% upon a change of control triggering event, as defined in the indentures. The Euro Notes are subject to typical events of default, including bankruptcy and insolvency events, nonpayment and the acceleration of certain subsidiary indebtedness exceeding $100 million caused by a nonpayment default.

Credit Agreements

Our revolving, unsecured credit agreement dated as of June 21, 2018, as amended on August 14, 2019, May 11, 2020, and as further amended on December 10, 2021 (the “2018 Credit Agreement”) currently provides for borrowings of up to $1.0 billion and matures on August 9, 2024. Borrowings under the 2018 Credit Agreement bear interest at variable rates based on an average LIBOR for deposits in the relevant currency plus an applicable margin which ranges from 0.910% to 1.500%, depending on the Company’s credit rating from Standard & Poor’s Ratings Services LLC (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Inc. (“Fitch”). The applicable margin on the facility was 1.125% as of March 31, 2022. As of March 31, 2022 there were no borrowings outstanding under the 2018 Credit Agreement.

On August 14, 2019, the Company entered into the $1.2 billion 2019 Credit Facility with several banks and other financial institutions, which was amended and restated on December 15, 2020 and again on December 10, 2021. The lenders’ commitment to provide new loans under the amended 2019 Credit Facility permits up to four borrowings by the Company in an aggregate amount equal to $750 million. The 2019 Credit Facility terminates on December 9, 2022, with each such loan maturing 364 days after the funding of such loan. The Company can request that the maturity date of loans be extended for a period of up to four additional years, but any such extension is subject to the approval of the lenders. At the option of the Company, the borrowings under the 2019 Credit Facility bear interest at variable rates based on either the base rate or LIBOR for deposits in U.S. dollars, in each case plus an applicable margin which ranges from 0.000% to 0.375% for base rate borrowings or 0.875% to 1.375% for LIBOR borrowings, depending on the Company’s credit rating from S&P, Moody’s and Fitch. The applicable margin on the 2019 Credit Facility was 1.125% as of March 31, 2022. As of March 31, 2022, $250 million in borrowings were outstanding under the 2019 Credit Facility.

Borrowings under the under the 2019 Credit Facility and 2018 Credit Agreement (together the “Credit Agreements”) are conditioned upon satisfaction of certain conditions precedent, including the absence of defaults. The Company is subject to one financial covenant, as well as customary affirmative and negative covenants. The financial covenant requires that the Company’s consolidated net funded debt to consolidated EBITDA ratio (as such terms are defined in the Credit Agreements) be less than or equal to 4.00:1 for the fiscal quarter ending December 31, 2021 and 3.50:1 for fiscal quarters thereafter, subject to adjustments in accordance with the terms of the Credit Agreements relating to a consummation of an acquisition where the consideration includes cash proceeds from issuance of funded debt in excess of $500 million. The Credit Agreements also contain customary default provisions, including defaults for non-payment, breach of representations and warranties, insolvency, non-performance of covenants and cross-defaults to other material indebtedness. The occurrence of an event of default under the Credit Agreements could result in all loans and other obligations becoming immediately due and payable and each such Credit Agreement being terminated.

S-24

Commercial Paper Notes

On May 29, 2013, we entered into agreements to initiate a commercial paper program on a private placement basis under which we may issue unsecured commercial paper notes (the “Commercial Paper Notes”) from time-to-time up to a maximum aggregate principal amount outstanding at any time of $750.0 million. The proceeds from the issuance of the Commercial Paper Notes are used for general corporate purposes, including the repayment of other debt of the Company. The Credit Agreements are available to repay the Commercial Paper Notes, if necessary. Aggregate borrowings outstanding under the Credit Agreements and the Commercial Paper Notes will not exceed the $1.75 billion current maximum amount available under the Credit Agreements. The Commercial Paper Notes will be sold at a discount from par, or alternatively, will be sold at par and bear interest at rates that will vary based upon market conditions at the time of issuance. The maturities of the Commercial Paper Notes will vary but may not exceed 397 days from the date of issue. The definitive documents relating to the commercial paper program contain customary representations, warranties, default and indemnification provisions. At March 31, 2022, we had $222.4 million of Commercial Paper Notes outstanding bearing a weighted-average interest rate of approximately 1.12% and a weighted-average maturity of 17 days. The Commercial Paper Notes are classified as Current portion of long-term debt in our consolidated balance sheets at March 31, 2022.

Other

We have additional uncommitted credit lines with various U.S. and foreign financial institutions that provide for borrowings of up to approximately $200 million at March 31, 2022. Outstanding borrowings under these agreements were $58 million at March 31, 2022.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

This section is a summary of material U.S. federal income tax considerations relating to the ownership and disposition of the notes. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on existing U.S. federal income tax authorities, all of which are subject to change or differing interpretations, possibly with retroactive effect. There can be no assurance that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described herein, and we have not obtained, and do not intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of owning or disposing of the notes. The summary generally applies only to beneficial owners of the notes that purchase their notes in this offering for an amount equal to the “issue price” of the notes, which is the first price at which a substantial amount of the notes is sold for money to the public (not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, initial purchasers, placement agents or wholesalers), and that hold the notes as “capital assets” (generally, for investment). This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular beneficial owner in light of the beneficial owner’s circumstances (for example, persons subject to the alternative minimum tax provisions of the Internal Revenue Code of 1986, as amended (the “Code”), or a U.S. holder (as defined below) whose “functional currency” is not the U.S. dollar). Also, it is not intended to be wholly applicable to all categories of investors, some of which may be subject to special rules (such as dealers in securities, traders in securities that elect to use a mark-to-market method of accounting, accrual-method taxpayers subject to section 451(b) of the Code, banks, thrifts, regulated investment companies, real estate investment trusts, insurance companies, tax-exempt entities, tax-deferred or other retirement accounts, certain former citizens or residents of the United States, persons holding notes as part of a straddle, persons purchasing or selling notes as part of a wash sale for U.S. federal income tax purposes, entities treated as “controlled foreign corporations” or “passive foreign investment companies” for U.S. federal income tax purposes, or persons deemed to sell notes under the constructive sale provisions of the Code). Finally, the summary does not address the potential application of the Medicare tax on investment income, the effects of the U.S. federal estate and gift tax laws or the effects of any applicable non-U.S., state or local laws.

INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF U.S. FEDERAL INCOME, ESTATE OR GIFT TAX LAWS, NON-U.S., STATE AND LOCAL LAWS AND TAX TREATIES TO THEIR PARTICULAR SITUATIONS.

As used herein, the term “U.S. holder” means a beneficial owner of notes that, for U.S. federal income tax purposes, is (1) a citizen or individual resident of the United States, (2) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state of the United States, or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust if it (x) is subject to the primary supervision of a U.S. court and the control of one of more U.S. persons or (y) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

A “non-U.S. holder” is a beneficial owner of notes (other than a partnership for U.S. federal income tax purposes) that is not a U.S. holder.

If a partnership (or other entity or arrangement treated as a partnership) for U.S. federal income tax purposes is a beneficial owner of a note, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. A beneficial owner of notes that is a partnership, and partners in such a partnership, should consult his, her or its tax advisor about the U.S. federal income tax consequences of owning and disposing of the notes.

S-26

U.S. Holders

The following discussion is limited to the U.S. federal income tax consequences relevant to a U.S. holder (as defined above).

Certain Additional Payments

Under the terms of the notes, there are circumstances in which we might be required to make payments on a note that would increase the yield of the note, as described under “Description of the Notes — Offer to Repurchase Upon Change of Control Triggering Event.” Under U.S. Treasury regulations, the possibility of such excess amounts being paid will not affect the amount of interest income a holder recognizes, in advance of the payment of such excess amounts, if there is only a remote possibility as of the date the notes were issued that the holder would receive such amounts. We believe that there is only a remote possibility that we would be required to make such payments, and therefore we do not intend to treat the notes as subject to the special rules governing “contingent payment debt instruments.” Our position that the notes are not subject to these special rules is binding on a holder unless the holder discloses a contrary position in the manner required by applicable U.S. Treasury regulations. If the IRS takes a contrary position, a U.S. holder may be required to accrue interest income based upon a “comparable yield” (as defined in the U.S. Treasury regulations) determined at the time of issuance of the notes (which is not expected to differ significantly from the actual yield on the notes), with adjustments to such accruals when any contingent payments are made that differ from the payments based on the comparable yield. In addition, any income on the sale, exchange, retirement or other taxable disposition of the notes would be treated as interest income rather than as capital gain. U.S. holders should consult their tax advisors regarding the tax consequences if the notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

Payments of Interest

A U.S. holder will be required to recognize as ordinary income any stated interest paid or accrued on the notes, in accordance with its regular method of tax accounting.

In general, if the stated principal amount of a debt instrument exceeds its issue price by at least a statutorily defined de minimis amount, a U.S. holder will be required to include such excess in income as “original issue discount” over the term of the instrument in accordance with a constant-yield method, irrespective of the holder’s regular method of tax accounting. Generally, original issue discount is considered to be de minimis if it is less than 0.25% of the instrument’s stated principal amount multiplied by the number of complete years from the issue date to maturity. We anticipate, and therefore this discussion assumes, that the notes will not be issued with original issue discount for U.S. federal income tax purposes.

Sale, Exchange or Other Taxable Disposition of Notes

A U.S. holder generally will recognize capital gain or loss if it disposes of a note in a sale, exchange or other taxable disposition. The U.S. holder’s gain or loss generally will equal the difference between the amount realized by it (other than amounts attributable to accrued but unpaid interest) and its tax basis in the note. The U.S. holder’s tax basis in the note generally will equal the amount it paid for the note. The portion of any amount realized that is attributable to accrued interest will not be taken into account in computing the U.S. holder’s capital gain or loss. Instead, that portion will be recognized as ordinary interest income to the extent that the U.S. holder has not previously included the accrued interest in income. The gain or loss recognized by the U.S. holder on the disposition of the note will be long-term capital gain or loss if it has held the note for more than one year, or short-term capital gain or loss if it has held the note for one year or less, at the time of the disposition. Long-term capital gains of non-corporate taxpayers currently are taxed at preferential rates. Short-term capital gains are taxed at ordinary income rates. The deductibility of capital losses is subject to limitations.

S-27

Non-U.S. Holders

The following discussion is limited to the U.S. federal income tax consequences relevant to a non-U.S. holder (as defined above).

Payments of Interest

Subject to the discussions below regarding the Foreign Account Tax Compliance Act (“FATCA”) and under “— Income or Gains Effectively Connected with a U.S. Trade or Business,” payments of interest on the notes to non-U.S. holders will generally qualify as “portfolio interest,” and thus will be exempt from U.S. federal income tax, including withholding of such tax, if the non-U.S. holder certifies its non-U.S. status as described below.

The portfolio interest exemption will not apply to payments of interest to a non-U.S. holder that:

The portfolio interest exemption applies only if the non-U.S. holder certifies its non-U.S. status. A non-U.S. holder can meet this certification requirement by providing a properly completed and executed IRS Form W-8BEN or W-8BEN-E or appropriate substitute form prior to the payment. If the non-U.S. holder holds the note through a financial institution or other agent acting on its behalf, it will be required to provide appropriate documentation to the agent.

Special certification rules apply to non-U.S. holders that are pass-through entities.

If the portfolio interest exemption does not apply to payments of interest to a non-U.S. holder, and subject to the discussion below under “—Income or Gains Effectively Connected with a U.S. Trade or Business,” these payments will be subject to withholding tax at a rate of 30% (or a lower treaty rate if the non-U.S. holder is eligible for the benefits of a tax treaty between the United States and its country of residence and provides appropriate certification of eligibility to the applicable withholding agent).

Sale, Exchange or Other Taxable Disposition of Notes

Subject to the discussion below regarding backup withholding, non-U.S. holders generally will not be subject to U.S. federal income or withholding tax on any gain realized on the sale, exchange or other taxable disposition of notes (other than with respect to payments attributable to accrued interest, which will be taxed as described under “— Payments of Interest” above) unless:

S-28

Income or Gains Effectively Connected with a U.S. Trade or Business.

If any interest on the notes or gain from the sale, exchange or other taxable disposition of the notes is effectively connected with a U.S. trade or business conducted by a non-U.S. holder, then the income or gain will be subject to U.S. federal income tax on a net-income basis at the regular graduated rates and generally in the same manner applicable to U.S. holders. If the non-U.S. holder is eligible for the benefits of a tax treaty between the United States and its country of residence, any “effectively connected” income or gain generally will be subject to U.S. federal income tax on a net-income basis only if it is also attributable to a permanent establishment or fixed base maintained by it in the United States. Payments of interest that are effectively connected with a U.S. trade or business conducted by the non-U.S. holder (and, if an applicable tax treaty requires, attributable to a U.S. permanent establishment or fixed base), and therefore included in the gross income of a non-U.S. holder, will not be subject to the 30% withholding tax discussed above under “—Non-U.S. Holders—Payments of Interest”, provided that the non-U.S. Holder claims exemption from withholding by timely filing a properly completed and executed IRS Form W-8ECI, or any appropriate substitute or successor form as the IRS designates, as applicable, prior to payment. If the non-U.S. holder is a corporation for U.S. federal income tax purposes, that portion of its earnings and profits that is effectively connected with its U.S. trade or business generally also will be subject to a “branch profits tax.” The branch profits tax rate is generally 30%, although an applicable income tax treaty might provide for a lower rate.

Backup Withholding and Information Reporting

The Code and U.S. Treasury regulations generally require persons who make specified payments to report the payments to the IRS. Among the specified payments are interest, dividends, and proceeds paid by brokers to their customers. This reporting regime is reinforced by “backup withholding” rules, which generally require the payor to withhold from payments subject to information reporting if the recipient has failed to provide a taxpayer identification number to the payor, furnished an incorrect identification number, failed to comply with applicable certification requirements or been repeatedly notified by the IRS that it has failed to report interest or dividends on its U.S. federal income tax returns. The backup withholding rate is currently 24%.

Payments of interest to U.S. holders of notes and payments made to U.S. holders by a broker upon a sale of notes generally will be subject to information reporting and backup withholding, unless the U.S. holder (1) is an exempt recipient, or (2) in the case of backup withholding, provides the payor with a correct taxpayer identification number and complies with applicable certification requirements. If a sale is made through a foreign office of a foreign broker, however, the sale will generally not be subject to either information reporting or backup withholding. This exception may not apply if the foreign broker is owned or controlled by U.S. persons, or is engaged in a U.S. trade or business.

The applicable withholding agent must report annually to the IRS the interest paid to each non-U.S. holder and the amount of tax withheld, if any, with respect to such interest, including any tax withheld pursuant to the rules described under “— Non-U.S. Holders — Payments of Interest” above and “— FATCA” below. Copies of these reports may be made available to tax authorities in the country where the non-U.S. holder resides. Payments to non-U.S. holders of interest on the notes may be subject to backup withholding unless the non-U.S. holder certifies its non-U.S. status on a properly completed and executed IRS Form W-8BEN or W-8BEN-E or appropriate substitute form. Payments made to non-U.S. holders by a broker upon a sale of the notes will not be subject to information reporting (except to the extent such payments are subject to withholding under FATCA, discussed below) or backup withholding as long as the non-U.S. holder certifies its non-U.S. status or otherwise establishes an exemption.

Any amounts withheld from a payment to a U.S. holder or non-U.S. holder with respect to the notes under the backup withholding rules generally will be allowed as a refund or can be credited against any U.S. federal income tax liability of the holder, provided the required information is timely furnished to the IRS.

S-29

FATCA

Provisions of the Code known as FATCA and U.S. Treasury regulations promulgated thereunder generally impose a 30% U.S. withholding tax on certain U.S.-source payments, including interest (including original issue discount), dividends and other fixed or determinable annual or periodical gain, profits, and income, and on the gross proceeds from a sale or other disposition of property of a type which can produce U.S.-source interest or dividends (“Withholdable Payments”), if paid to a foreign financial institution (whether as a beneficial owner or intermediary), unless such institution (i) enters into an agreement with the U.S. Department of the Treasury to collect and provide to the U.S. Department of the Treasury substantial information regarding its U.S. account holders, including certain account holders that are foreign entities with U.S. owners, (ii) satisfies the requirements of an intergovernmental agreement entered into by such institution’s country of residence and the United States, or (iii) qualifies for an exemption. These withholding requirements generally currently apply to payments of interest on the notes. Under proposed U.S. Treasury regulations, this withholding tax will not apply to the gross proceeds from the sale or other disposition of the notes. The preamble to these proposed U.S. Treasury regulations indicates that taxpayers may rely on them pending their finalization. FATCA also generally imposes a withholding tax of 30% on Withholdable Payments made to a non-financial foreign entity unless such entity provides the withholding agent with a certification that it does not have any substantial U.S. owners or certification identifying the direct and indirect substantial U.S. owners of the entity, or unless an exemption applies. An intergovernmental agreement between the United States and the non-U.S. entity’s jurisdiction may modify these requirements.

If FATCA withholding is imposed, a beneficial owner (other than certain foreign financial institutions) generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return and, in the case of a non-financial foreign entity, providing the IRS with certain information regarding its substantial U.S. owners (unless an exception applies). Prospective investors are urged to consult their tax advisors regarding the possible implications of FATCA on their ownership and disposition of the notes.

UNDERWRITING

BofA Securities, Inc., J.P. Morgan Securities LLC and Mizuho Securities USA, LLC are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amounts of notes set forth opposite the underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. The underwriters are obligated, severally but not jointly, to purchase all of the notes sold under the underwriting agreement if they purchase any of the notes. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated.

The underwriters propose to offer some of the notes directly to the public at the public offering prices set forth on the cover page of this prospectus supplement and some of the notes to dealers at the public offering price less a concession. The underwriters may allow, and dealers may reallow, a concession on sales to other dealers. After the initial offering of the notes to the public, the representatives may change the public offering prices and concessions.

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

We estimate that our total expenses for this offering will be approximately $4 million.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

S-31

Each series of the notes is a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

In connection with the offering, the underwriters may purchase and sell notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time without notice.

Certain of the underwriters or their affiliates have performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. In addition, affiliates of some of the underwriters are lenders, and in some cases agents or managers for the lenders, under our Revolving Credit Facility.

To the extent any of the underwriters or their affiliates own any of the 2024 Notes, upon application of the net proceeds of this offering to redeem the outstanding the 2024 Notes, such underwriters or affiliates would receive a portion of the net proceeds of this offering. To the extent any of the underwriters or their affiliates are agents, holders, lenders and/or counterparties under or to any of the Company’s commercial paper or other indebtedness that may be repaid with a portion of the net proceeds of this offering, such underwriters or affiliates would receive a portion of the net proceeds of this offering. In addition, U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee under the indenture governing the notes.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of those underwriters or their affiliates that have a lending relationships with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit

S-32

default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We expect that delivery of the notes will be made to investors on or about May 13, 2022, which will be the third business day following the date of the final prospectus supplement (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the delivery of the notes hereunder on a day prior to the second business day before the date of initial delivery of the notes will be required, by virtue of the fact that the notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their advisors.

DESCRIPTION OF COMMON STOCK

General

The following briefly summarizes the provisions of Albemarle’s amended and restated articles of incorporation and amended and restated bylaws (which we collectively refer to in this prospectus as the Albemarle organizational documents) that would be important to holders of Albemarle common stock. The following summary of Albemarle common stock is subject in all respects to applicable Virginia law and the Albemarle organizational documents, which are exhibits to the registration statement that contains this prospectus. In this “Description of Common Stock” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries.

Authorized Shares

Albemarle’s amended and restated articles of incorporation authorize the issuance of 150,000,000 shares of common stock, $0.01 par value per share and 15,000,000 shares of preferred stock. As of September 30, 2019, there were 106,031,088 shares of Albemarle common stock issued and outstanding, which were held by 2,402 shareholders of record, and no shares of Albemarle preferred stock were issued and outstanding.

Voting Rights

Holders of Albemarle common stock are entitled to one vote per share on all matters voted on generally by shareholders, including the election of directors. Albemarle’s amended and restated articles of incorporation do not provide for cumulative voting for the election of directors, which means that the holders of a majority of the outstanding shares of Albemarle common stock have the capacity to elect all of the members of the Albemarle board of directors.

Except as otherwise required by law or with respect to any outstanding class or series of Albemarle preferred stock, the holders of Albemarle common stock possess all voting power.

Under Albemarle’s amended and restated articles of incorporation, shareholder action is generally effective if the votes cast in favor of the action exceed the votes cast against the action. But the election of directors requires a plurality of the votes cast by Albemarle shareholders at a meeting at which a quorum is present. However, Albemarle’s amended and restated articles of incorporation require the affirmative vote of at least a majority of the outstanding shares of Albemarle common stock for the approval of mergers, statutory share exchanges, sales or other dispositions of all or substantially all of Albemarle’s assets outside the usual and regular course of business or dissolution of Albemarle, except that the affirmative vote of 75% of the outstanding shares of Albemarle common stock is required for approval of an affiliated transaction. An affiliated transaction generally is defined as any of the following transactions:

5

The supermajority voting requirement does not apply to a transaction with a shareholder who, together with his or her affiliates and associates, became the beneficial owner of more than 10% of any class of Albemarle outstanding voting shares as of the close of business on February 28, 1994, the date of the distribution by Ethyl Corporation to its shareholders of all of the outstanding shares of Albemarle common stock.

Furthermore, the affirmative vote of the holders of 75% of the voting power of Albemarle’s outstanding shares must approve an amendment to provisions in Albemarle’s amended and restated articles of incorporation relating to the supermajority voting requirement for affiliated transactions.

Notice

Except as otherwise required by the Virginia Stock Corporation Act (the “VSCA”), written notice stating the date, time and place of every meeting, and the purpose or purposes of any special meeting of Albemarle shareholders, must be sent not less than 10 nor more than 60 days before the date of the meeting to each shareholder of record entitled to vote at such meeting.

Quorum

A majority of the shares entitled to vote, represented in person or by proxy, constitutes a quorum.

Shareholder Proposals

Albemarle’s amended and restated bylaws provide that shareholders seeking to bring business before an annual meeting of shareholders or nominate candidates for election as directors must provide timely notice of their proposal in writing to the Secretary of Albemarle. Generally, to be timely, a shareholder’s notice must be received at Albemarle’s principal executive offices not less than 90 nor more than 120 days prior to the first anniversary of the previous year’s annual meeting. If the annual meeting is scheduled more than 30 days before, or 70 days after the first anniversary of the previous year’s annual meeting, the shareholder must provide notice to the Secretary of Albemarle no earlier than within 90 to 120 days before the meeting or 10 days after the meeting’s public announcement, whichever is later. Albemarle’s amended and restated bylaws also specify requirements as to the form and content of a shareholder’s notice.

Dividend Rights; Rights Upon Liquidation

Subject to any preferential rights of holders of any shares of Albemarle preferred stock that may be outstanding, holders of shares of Albemarle common stock are entitled to receive dividends and other distributions on their shares of common stock out of assets legally available for distribution when, as and if authorized and declared by the Albemarle board of directors and to share ratably in Albemarle’s assets legally available for distribution to its shareholders in the event of its liquidation, dissolution or winding-up.

Miscellaneous

Holders of Albemarle common stock have no preferences or preemptive, conversion, exchange, redemption or sinking fund rights. Shares of Albemarle common stock will not be liable for further calls or assessments by Albemarle, and the holders of Albemarle common stock will not be liable for any of Albemarle’s liabilities.

Albemarle’s amended and restated bylaws also provide that unless Albemarle consents in writing to the selection of an alternative forum, the United States District Court for the Eastern District of Virginia, Alexandria Division, or in the event that court lacks jurisdiction to hear such action, the Circuit Court of the County of Fairfax, Virginia, will be the sole and exclusive forum for any derivative action brought on behalf of Albemarle, any action asserting a claim of breach of a legal duty owed by any current or former director, officer or other employee or agent of Albemarle to Albemarle or Albemarle shareholders, any action arising pursuant to the

6

VSCA or Albemarle’s organizational documents or any action asserting a claim governed by the internal affairs doctrine.

Albemarle common stock is listed on the NYSE under the symbol “ALB.”

Anti-Takeover Provisions

The Albemarle organizational documents and Virginia law contain provisions that may have the effect of impeding, delaying or discouraging the acquisition of control of Albemarle by means of a tender or exchange offer, proxy fight, merger or share exchange, open market purchases or otherwise in a transaction not approved by the Albemarle board of directors. These provisions are designed to reduce, or have the effect of reducing, Albemarle’s vulnerability to an unsolicited proposal for the restructuring or sale of all or substantially all of Albemarle’s assets or an unsolicited takeover attempt that the Albemarle board of directors does not believe is in the best interests of its shareholders.

Under Albemarle’s amended and restated articles of incorporation, the Albemarle board of directors has the authority, without further shareholder approval, to issue preferred stock in classes or series and to fix the designations, voting power, preferences and rights of the shares of each class or series and any qualifications, limitations or restrictions with respect to that class or series. Under this authority, the Albemarle board of directors could create and issue a class or series of preferred stock with rights, preferences or restrictions that have the effect of discriminating against an existing or prospective holder of Albemarle’s capital stock as a result of such holder beneficially owning or commencing a tender offer for a substantial amount of Albemarle common stock. One of the effects of authorized but unissued and unreserved shares of preferred stock may be to render it more difficult for, or discourage an attempt by, a potential acquiror to obtain control of Albemarle by means of a merger, share exchange, tender or exchange offer, proxy contest or otherwise, and thereby protect the continuity of Albemarle’s management. The issuance of shares of preferred stock may have the effect of delaying, deferring or preventing a change in control of Albemarle without any further action by Albemarle shareholders.

Other provisions of the Albemarle organizational documents that may make replacing the Albemarle board of directors more difficult include:

Affiliated Transactions Statute

Virginia law contains provisions governing affiliated transactions. In general, these provisions prohibit a Virginia corporation from engaging in affiliated transactions with any holder of more than 10% of any class of its outstanding voting shares, or an interested shareholder, for a period of three years following the date that such person became an interested shareholder unless:

7

After three years, any such transaction must satisfy certain fair price requirements in the statute or be approved by the holders of two-thirds of the voting shares, other than the shares beneficially owned by the interested shareholder. For a description of the affiliated transactions subject to this approval requirement, see “—Voting Rights.”

Control Share Acquisitions Statute

Virginia law also contains provisions relating to control share acquisitions, which are transactions causing the voting power of any person acquiring beneficial ownership of shares of a Virginia public corporation to meet or exceed certain threshold percentages (20%, 33 1/3% or 50%) of the total votes entitled to be cast for the election of directors. Shares acquired in a control share acquisition have no voting rights unless:

The acquiring person may require that a special meeting of the shareholders be held to consider the grant of voting rights to the shares acquired in the control share acquisition.

As permitted by Virginia law, the Albemarle board of directors has adopted a bylaw providing that the control share acquisition provisions of Virginia law do not apply to the acquisition of its shares.

Transfer Agent and Registrar

EQ Shareowner Services is the transfer agent and registrar for Albemarle common stock.

Limitation of Liability and Indemnification Matters

Albemarle’s amended and restated articles of incorporation provide that no director or officer shall be liable to Albemarle or its shareholders for monetary damages except for liability resulting from such person’s willful misconduct or a knowing violation of the criminal law or of any federal or state securities law.

Albemarle’s amended and restated articles of incorporation require Albemarle to indemnify any director or officer who was or is a party to a proceeding (including a proceeding brought by a shareholder in the right of Albemarle or brought by or on behalf of Albemarle shareholders) due to his or her status as a director or officer of Albemarle or who was or is serving at Albemarle’s request as a director, officer, trustee or partner of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. This indemnification covers the obligation to pay a judgment, settlement, penalty, fine or excise tax assessed with respect to an employee benefit plan and all reasonable expenses incurred by any such director or officer. The board of directors, by a majority vote of a quorum of disinterested directors or, under certain circumstances, independent legal counsel, or by the shareholders (excluding shares owned by or under the control of directors party to the proceeding), must determine that the conduct of the director or officer seeking indemnification does not constitute willful misconduct or a knowing violation of the criminal law.

Insofar as indemnification for liabilities under the Securities Act may be permitted to directors, officers and controlling persons of Albemarle pursuant to the foregoing provisions or otherwise, we have been informed that, in the opinion of the SEC, indemnification for liabilities under the Securities Act is against public policy and is unenforceable.

8

DESCRIPTION OF PREFERRED STOCK

We may issue preferred stock in one or more classes or series, as described below. The following briefly summarizes the provisions of our amended and restated articles of incorporation that would be important to holders of our preferred stock. The following description may not be complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of our amended and restated articles of incorporation, which is an exhibit to the registration statement that contains this prospectus. Reference to a class or series of preferred stock means all of the shares of preferred stock issued as part of the same class or series under articles of amendment filed as part of our restated articles of incorporation. In this “Description of Preferred Stock” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries.

The description of most of the financial and other specific terms of each class or series of preferred stock will be in the prospectus supplement accompanying this prospectus. Those terms may vary from the terms described in this prospectus. As you read this section, please remember that the specific terms of each class or series of preferred stock as described in the prospectus supplement applicable to the particular series of preferred stock will supplement and may modify or replace the general terms described in this section. If there are differences between the prospectus supplement applicable to the particular class or series of preferred stock and this prospectus, the prospectus supplement will control. Thus, the statements we make in this section may not apply to each series of preferred stock.

Our Authorized Preferred Stock

Under our amended and restated articles of incorporation our board of directors is authorized, without further action by our shareholders, to:

Such rights and preferences may be superior to common stock as to dividends, distributions of assets (upon liquidation or otherwise) and voting rights. Undesignated shares of preferred stock may be convertible into shares of any other series or class of stock, including common stock, if our board of directors so determines. Our board of directors will fix the terms of the class or series of preferred stock it designates by resolution adopted before we issue any shares of the class or series of preferred stock.

The applicable prospectus supplement relating to the particular class or series of preferred stock will contain a description of the specific terms of that class or series as fixed by our board of directors, including, as applicable:

9

When we issue and receive payment for shares of preferred stock, the shares will be fully paid and nonassessable, which means that their holders will have paid at least the par value thereof in full and that we may not ask them to surrender additional funds. Holders of preferred stock will not have any preemptive subscription rights to acquire more of our stock. Unless otherwise specified in the applicable prospectus supplement relating to a particular series of preferred stock, each class or series of preferred stock will be of equal rank in all respects (1) with each other class or series of preferred stock and (2) prior to our common stock, as to dividends and any distribution of our assets.

The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future. Our board of directors may cause shares of preferred stock to be issued in public or private transactions for any proper corporate purpose and may include issuances to obtain additional financing in connection with acquisitions, and issuances to officers, directors and employees pursuant to benefit plans. Our board of directors’ ability to issue shares of preferred stock may discourage attempts by others to acquire control of us without negotiation with our board of directors, as it may make it difficult for a person to acquire us without negotiating with our board of directors.

Redemption

If so specified in the applicable prospectus supplement, a class or series of preferred stock may be redeemable at any time, in whole or in part, at our option or the holder’s, and may be mandatorily redeemed.

Any restriction on the repurchase or redemption by us of our preferred stock while we are in arrears in the payment of dividends will be described in the applicable prospectus supplement.

Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable.

Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date on shares of preferred stock called for redemption and all rights of holders of these shares will terminate except for the right to receive the redemption price.

Dividends

Holders of each class or series of preferred stock will be entitled to receive dividends when, as and if declared by our board of directors from funds legally available for payment of dividends. The rates and dates of payment of dividends will be set forth in the applicable prospectus supplement relating to each class or series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books on the record dates fixed by the board of directors. Dividends on any class or series of preferred stock may be cumulative or noncumulative, as set forth in the applicable prospectus supplement.

We may not declare, pay or set apart funds for payment of dividends on a particular class or series of preferred stock unless full dividends on any other class or series of preferred stock that ranks equally with or senior to the class or series of preferred stock have been paid or sufficient funds have been set apart for payment for either of the following:

10

Partial dividends declared on shares of any class or series of preferred stock and other class or series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for each class or series of preferred stock.

In case dividends on all shares of preferred stock for any quarterly dividend period are not paid in full, all such shares will participate ratably in any partial payment of dividends for such period in proportion to the full amounts of dividends for such period to which they are respectively entitled.

Conversion or Exchange Rights

The applicable prospectus supplement relating to any class or series of preferred stock that is convertible, exercisable or exchangeable will state the terms on which shares of that class or series are convertible into, exercisable or exchangeable for shares of common stock, another class or series of our preferred stock, our other securities or debt or equity securities of third parties.

Liquidation Preference

In the event of our voluntary or involuntary liquidation, dissolution or winding-up, holders of each class or series of our preferred stock will have the right to receive distributions upon liquidation in the amount described in the applicable prospectus supplement relating to each class or series of preferred stock. These distributions will be made before any distribution is made on the common stock or on any securities ranking junior to the preferred stock upon liquidation, dissolution or winding-up.

If the liquidation amounts payable relating to the preferred stock of any class or series and any other securities of equal rank regarding liquidation rights are not paid in full, the holders of the preferred stock of that class or series and the other securities will have the right to a ratable portion of our available assets, up to the full liquidation preference of each security. Holders of these series of preferred stock or other securities will not be entitled to any other amounts from us after they have received their full liquidation preference.

Voting Rights

The holders of shares of preferred stock will have no voting rights, except:

Transfer Agent and Registrar

The transfer agent, registrar and dividend disbursement agent for the preferred stock will be stated in the applicable prospectus supplement. The registrar for shares of preferred stock will send notices to shareholders of any meetings at which holders of the preferred stock have the right to elect directors or to vote on any other matter.

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of the debt securities that may be offered by this prospectus. This section does not describe every aspect of the indenture or the debt securities. This summary is subject to and qualified in its entirety by reference to all the provisions of the indenture, including definitions of some of the terms used in the indenture. You must look to the indenture for the most complete description of what we describe in summary form in this prospectus and the applicable prospectus supplement. A copy of the indenture and a form of supplemental indenture are filed as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” for information on how to obtain a copy. You should also refer to the Trust Indenture Act of 1939, certain terms of which are made a part of the indenture by reference. In this “Description of Debt Securities” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries, and references to “Notes” are to the debt securities.

The terms of the series described in the prospectus supplement relating to that series may vary from the terms described in this prospectus. The prospectus supplement relating to each series of debt securities will be attached to the front of this prospectus. There may also be a further prospectus supplement, known as a pricing supplement, which contains the precise terms of debt securities we are offering.

We may issue as many distinct series of debt securities under the indenture as we wish without limitation as to aggregate principal amount under the terms of the indenture. The indenture does not limit our ability to incur additional indebtedness. This section summarizes the material terms of the debt securities that are common to all series, although the prospectus supplement that describes the terms of each series of debt securities may also describe differences with the material terms summarized in this prospectus.

We may issue senior or subordinated debt securities. Neither the senior debt securities nor the subordinated debt securities will be secured by any of our property or assets. Thus, by owning a debt security, you are one of our unsecured creditors.

The senior debt securities will constitute part of our senior debt and will rank equally with all of our other unsecured and unsubordinated debt. The senior debt securities will be issued under the indenture. The indenture has been qualified under the Trust Indenture Act. The indenture is an exhibit to the registration statement of which this prospectus is a part.

The subordinated debt securities will constitute part of our subordinated debt and will be subordinate in right of payment to all of our “senior indebtedness,” as defined in the indenture. The subordinated debt securities will be issued under the indenture. The prospectus supplement for any series of subordinated debt securities will indicate the approximate amount of senior indebtedness outstanding as of the end of the most recent fiscal quarter.

“Debt securities” in this prospectus refers to both the senior debt securities and the subordinated debt securities.

The trustee has two main roles:

We may issue the debt securities as original issue discount debt securities, which are securities that are offered and sold at a substantial discount to their stated principal amount. The prospectus supplement relating to original

12

issue discount debt securities will describe federal income tax consequences and other special considerations applicable to any such debt securities. See “—Interest and Interest Rates—Original Issue Discount Notes” below. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail below and in the prospectus supplement relating to any such debt securities. See “—Indexed Notes” and “Special Provisions Relating to Foreign Currency Debt Securities” below. The prospectus supplement relating to specific debt securities will also describe any special considerations and any material additional tax considerations applicable to such debt securities.

In addition, the specific financial, legal and other terms relating to a particular series of debt securities will be described in a prospectus supplement and any pricing supplement relating to the series. The prospectus supplement relating to a series of debt securities will describe, to the extent applicable, the following terms of the series:

13

Form, Exchange and Transfer

The debt securities will be issued:

A global security will be issued in denominations equal to the aggregate principal amount of outstanding debt securities represented by that global security. See “—Legal Ownership” below for additional information regarding global securities and the limitations on your rights as the beneficial owner of an interest in a global security.

You may have your debt securities broken into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange.

You may exchange or transfer debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform the service ourselves. The entity performing the role of maintaining the list of registered holders is called the security registrar. It will also register transfers of the debt securities.

You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If we designate additional transfer agents, they will be named in the prospectus supplement. We may cancel the designation of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

14

Redemption

Provisions relating to the redemption of debt securities, if any, will be set forth in the applicable prospectus supplement. Unless we state otherwise in the applicable prospectus supplement, we may redeem debt securities only upon notice sent at least 30 but not more than 60 days before the date fixed for redemption.

Interest and Interest Rates

General

Each debt security will begin to accrue interest from the date it is originally issued. The related prospectus supplement or term sheet will specify each debt security as a Fixed Rate Note, a Floating Rate Note, an Amortizing Note or an Indexed Note and describe the method of determining the interest rate, including any spread and/or spread multiplier. For an Indexed Note, the related prospectus supplement or term sheet also will describe the method for the calculation and payment of principal and interest. The prospectus supplement or term sheet for a Floating Rate Note or Indexed Note may also specify a maximum and a minimum interest rate.

A debt security may be issued as a Fixed Rate Note or a Floating Rate Note or as a Note that combines fixed and floating rate terms.

Each interest payment on a debt security will include interest accrued from, and including, the issue date or the last Interest Payment Date (as defined below), as the case may be, to but excluding the applicable Interest Payment Date or the Maturity Date (as defined below), as the case may be.

Interest on the debt securities denominated in U.S. dollars will be paid by check mailed on an Interest Payment Date other than a Maturity Date to the persons entitled thereto to the addresses of such holders as they appear in the security register or, at our option, by wire transfer to a bank account maintained by the holder. The principal of, premium, if any, and interest on debt securities denominated in U.S. dollars, together with interest accrued and unpaid thereon, due on the Maturity Date will be paid in immediately available funds upon surrender of such debt securities at the corporate trust office of the applicable trustee in The City of New York, or, at our option, by wire transfer of immediately available funds to an account with a bank designated at least 15 calendar days prior to the Maturity Date by the applicable registered holder, provided the particular bank has appropriate facilities to receive these payments and the particular debt security is presented and surrendered at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, in time for the trustee to make these payments in accordance with its normal procedures. Notwithstanding the foregoing, if debt securities are held in the form of global securities, all payments will be made in accordance with the applicable procedures of the depositary.

Fixed Rate Notes

The prospectus supplement or term sheet for debt securities with a fixed interest rate (“Fixed Rate Notes”) will specify a fixed interest rate payable semiannually in arrears on dates specified in such prospectus supplement or term sheet (each, with respect to Fixed Rate Notes, an “Interest Payment Date”). Unless otherwise specified in a prospectus supplement or term sheet, interest on Fixed Rate Notes will be computed on the basis of a 360-day year of twelve 30-day months. If the stated maturity date, any redemption date or any repayment date (together referred to as the “Maturity Date”) or an Interest Payment Date for any Fixed Rate Note is not a Business Day, principal of, premium, if any, and interest on that Note will be paid on the next Business Day, and no interest will accrue from and after the Maturity Date or Interest Payment Date. Interest on Fixed Rate Notes will be paid to holders of record as of each Regular Record Date. Unless otherwise specified in a prospectus supplement or term sheet, a “Regular Record Date” will be the fifteenth calendar day (whether or not a Business Day) next preceding the applicable Interest Payment Date.

15

Original Issue Discount Notes

We may issue original issue discount debt securities (including zero coupon debt securities) (“OID Notes”), which are debt securities issued at a discount from the principal amount payable on the Maturity Date. There may not be any periodic interest payments on OID Notes. For OID Notes, interest normally accrues during the life of the Note and is paid on the Maturity Date. Upon a redemption, repayment or acceleration of the maturity of an OID Note, the amount payable will be determined as set forth under “—Redemption.” This amount normally is less than the amount payable on the stated maturity date.

Amortizing Notes

We may issue amortizing debt securities, which are Fixed Rate Notes for which combined principal and interest payments are made in installments over the life of each debt security (“Amortizing Notes”). Payments on Amortizing Notes are applied first to interest due and then to the reduction of the unpaid principal amount. The related prospectus supplement or term sheet for an Amortizing Note will include a table setting forth repayment information.

Floating Rate Notes

Each debt security whose interest is determined by reference to an interest rate basis or formula is referred to herein as a “Floating Rate Note.” That basis or formula may be based on:

The prospectus supplement or term sheet will also indicate any spread and/or spread multiplier, which would be applied to the interest rate formula to determine the interest rate. Any Floating Rate Note may have a maximum or minimum interest rate limitation. In addition to any maximum interest rate limitation, the interest rate on the Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application.

We will appoint a calculation agent to calculate interest rates on the Floating Rate Notes.

As used in this prospectus, “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York; provided, however, that, with respect to debt securities denominated in a currency other than the U.S. dollar, the day is also not a day on which commercial banks are authorized or required by law, regulation or executive order to close in the Principal Financial Center (as defined below) of the country issuing the specified currency; provided, further, that, with respect to debt securities as to which LIBOR is an applicable interest rate basis, the day is also a London Business Day. For debt securities denominated in

16

euro, the term Business Day means any day that is not a Saturday or Sunday, and is also a day on which the Trans-European Automated Real Time Gross Settlement Express Transfer (“TARGET”) System is operating, which we will refer to as a “TARGET Business Day.” “London Business Day” means a day on which commercial banks are open for business (including dealings in the designated LIBOR Currency) in London.

“Principal Financial Center” means (i) the capital city of the country issuing the specified currency or (ii) the capital city of the country to which the designated LIBOR Currency relates, as applicable, except that the term “Principal Financial Center” means the following cities in the case of the following currencies:

and in the event the LIBOR Currency is euro, the “Principal Financial Center” is London.

Unless otherwise specified in a prospectus supplement or term sheet, the “Calculation Date,” if applicable, relating to the date (each, an “Interest Determination Date”) on which the applicable interest rate for one or more classes of Floating Rate Notes will be determined for the next succeeding interest period will be the earlier of (i) the tenth calendar day after such Interest Determination Date or, if such day is not a Business Day, the next succeeding Business Day, or (ii) the Business Day immediately preceding the relevant Interest Payment Date or the Maturity Date, as the case may be.

Upon the request of the beneficial holder of any Floating Rate Note, the calculation agent will provide the interest rate then in effect and, if different, when available, the interest rate that will become effective on the next Interest Reset Date (as defined below) for the Floating Rate Note.

Change of Interest Rate. The interest rate on each Floating Rate Note may be reset daily, weekly, monthly, quarterly, semiannually, annually or on some other specified basis (each, an “Interest Reset Date”). Unless otherwise specified in a prospectus supplement or term sheet, the Interest Reset Date will be:

The related prospectus supplement or term sheet describes the initial interest rate or interest rate formula on each Note. That rate is effective until the following Interest Reset Date. Thereafter, the interest rate will be the rate determined on each Interest Determination Date. Each time a new interest rate is determined, it becomes effective on the following Interest Reset Date. If any Interest Reset Date is not a Business Day, then the Interest Reset Date is postponed to the next Business Day, except, in the case of LIBOR and EURIBOR Notes, if the next Business Day is in the next calendar month, the Interest Reset Date is the immediately preceding Business Day.

17

Date Interest Rate Is Determined. The Interest Determination Date for all CD and CMT Rate Notes is the second Business Day before the Interest Reset Date and for all LIBOR Notes will be the second London Business Day immediately preceding the applicable Interest Reset Date (unless the LIBOR Currency is Sterling, in which case the Interest Determination Date will be the Interest Reset Date).

The Interest Determination Date for EURIBOR Notes will be the second TARGET Business Day immediately preceding the applicable Interest Reset Date.

The Interest Determination Date for Treasury Rate Notes will be the day of the week in which the Interest Reset Date falls on which Treasury bills of the Index Maturity are normally auctioned. Treasury bills are usually sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is usually held on Tuesday. Sometimes, the auction is held on the preceding Friday. If an auction is held on the preceding Friday, that day will be the Interest Determination Date relating to the Interest Reset Date occurring in the next week.

The Interest Determination Date for all Commercial Paper Rate, Federal Funds Rate and Prime Rate Notes will be the first Business Day preceding the Interest Reset Date.

The Interest Determination Date for an Eleventh District Cost of Funds Rate Note is the last Business Day of the month immediately preceding the applicable Interest Reset Date in which the Federal Home Loan Bank of San Francisco published the applicable rate.

The Interest Determination Date relating to a Floating Rate Note with an interest rate that is determined by reference to two or more interest rate bases will be the most recent Business Day which is at least two Business Days before the applicable Interest Reset Date for each interest rate for the applicable Floating Rate Note on which each interest rate basis is determinable.

Payment of Interest. Unless otherwise specified in a prospectus supplement or term sheet, interest is paid as follows:

Unless otherwise specified in the applicable prospectus supplement, interest on a Floating Rate Note will be payable beginning on the first Interest Payment Date after its issue date to holders of record at the close of business on each Regular Record Date, which is the fifteenth day (whether or not a Business Day) next preceding the applicable Interest Payment Date, unless the issue date falls after a Regular Record Date and on or prior to the related Interest Payment Date, in which case payment will be made to holders of record at the close of business on the Regular Record Date next preceding the second Interest Payment Date following the issue date. If an Interest Payment Date (but not the Maturity Date) is not a Business Day then the Interest Payment Date will be postponed to the next Business Day. However, in the case of LIBOR and EURIBOR Notes, if the next Business Day is in the next calendar month, the Interest Payment Date will be the immediately preceding Business Day. If the Maturity Date of any Floating Rate Note is not a Business Day, principal of, premium, if any, and interest on that Note will be paid on the next Business Day, and no interest will accrue from and after the Maturity Date.

18

Accrued interest on a Floating Rate Note is calculated by multiplying the principal amount of a Note by an accrued interest factor. The accrued interest factor is the sum of the interest factors calculated for each day in the period for which accrued interest is being calculated. The interest factor for each day is computed by dividing the interest rate in effect on that day by (1) the actual number of days in the year, in the case of Treasury Rate Notes or CMT Rate Notes, or (2) 360, in the case of other Floating Rate Notes. The interest factor for Floating Rate Notes for which the interest rate is calculated with reference to two or more interest rate bases will be calculated in each period in the same manner as if only one of the applicable interest rate bases applied. All percentages resulting from any calculation are rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward. For example, 9.876545% (or .09876545) will be rounded to 9.87655% (or .0987655). Dollar amounts used in the calculation are rounded to the nearest cent (with one-half cent being rounded upward).

CD Rate Notes. The “CD Rate” for any Interest Determination Date is the rate on that date for negotiable U.S. dollar certificates of deposit having the Index Maturity described in the related prospectus supplement or term sheet, as published in H.15 prior to 3:00 p.m., New York City time, on the Calculation Date, for that Interest Determination Date under the heading “CDs (secondary market).” The “Index Maturity” is the period to maturity of the instrument or obligation with respect to which the related interest rate basis or formula will be calculated.

The following procedures will be followed if the CD Rate cannot be determined as described above:

“H.15” means the daily statistical release designated as such, or any successor publication, published by the Board of Governors of the Federal Reserve System.

LIBOR Notes. The “LIBOR” for any Interest Determination Date is the rate for deposits in the LIBOR Currency having the Index Maturity specified in such prospectus supplement or term sheet as such rate is displayed on Reuters on page LIBOR01 (or any other page as may replace such page on such service for the purpose of displaying the London interbank rates of major banks for the designated LIBOR Currency) (“Reuters Page LIBOR01”) as of 11:00 a.m., London time, on such LIBOR Interest Determination Date.

The following procedure will be followed if LIBOR cannot be determined as described above and any additional provisions with respect to LIBOR or an alternative rate LIBOR will be set forth in a prospectus supplement:

“LIBOR Currency” means the currency specified in the applicable prospectus supplement or term sheet as to which LIBOR shall be calculated or, if no such currency is specified in the applicable prospectus supplement or term sheet, U.S. dollars.

20

EURIBOR Notes. The “EURIBOR” for any Interest Determination Date is the offered rate for deposits in euro having the Index Maturity specified in the applicable prospectus supplement or term sheet, beginning on the second TARGET Business Day after such EURIBOR Interest Determination Date, as that rate appears on Reuters Page EURIBOR 01 as of 11:00 a.m., Brussels time, on such EURIBOR Interest Determination Date.

The following procedure will be followed if EURIBOR cannot be determined as described above:

Federal Funds Rate Notes. The “Federal Funds Rate” will be calculated by reference to either the “Federal Funds (Effective) Rate,” the “Federal Funds Open Rate” or the “Federal Funds Target Rate,” as specified in the applicable prospectus supplement or term sheet. The Federal Funds Rate is the rate determined by the calculation agent, with respect to any Interest Determination Date relating to a Floating Rate Note for which the interest rate is determined with reference to the Federal Funds Rate (a “Federal Funds Rate Interest Determination Date”), in accordance with the following provisions:

21

Prime Rate Notes. The “Prime Rate” for any Interest Determination Date is the rate on that date, as published in H.15 by 3:00 p.m., New York City time, on the Calculation Date for that Interest Determination Date under the heading “Bank Prime Loan” or, if not published by 3:00 p.m., New York City time, on the related Calculation Date, the rate on such Interest Determination Date as published in H.15, or such other recognized electronic source used for the purpose of displaying such rate, under the caption “Bank Prime Loan.”

The following procedures will be followed if the Prime Rate cannot be determined as described above:

22

“Reuters Page USPRIME1” means the display on Reuters (or any successor service) on the “USPRIME1 Page” (or such other page as may replace the USPRIME1 Page on such service) for the purpose of displaying prime rates or base lending rates of major U.S. banks.

Treasury Rate Notes. The “Treasury Rate” for any Interest Determination Date is the rate from the auction of direct obligations of the United States (“Treasury bills”) having the Index Maturity specified in such prospectus supplement or term sheet under the caption “INVEST RATE” on the display on Reuters page USAUCTION10 (or any other page as may replace such page on such service) or page USAUCTION11 (or any other page as may replace such page on such service) or, if not so published at 3:00 p.m., New York City time, on the related calculation date, the bond equivalent yield (as defined below) of the rate for such treasury bills as published in H.15, or such other recognized electronic source used for the purpose of displaying such rate, under the caption “U.S. Government Securities/Treasury Bills/Auction High.” If such rate is not so published in the related H.15 or another recognized source by 3:00 p.m., New York City time, on the related calculation date, the Treasury Rate on such Treasury Rate Interest Determination Date shall be the bond equivalent yield of the auction rate of such Treasury bills as announced by the United States Department of the Treasury. In the event that such auction rate is not so announced by the United States Department of the Treasury on such calculation date, or if no such auction is held, then the Treasury Rate on such Treasury Rate Interest Determination Date shall be the bond equivalent yield of the rate on such Treasury Rate Interest Determination Date of Treasury bills having the Index Maturity specified in the applicable prospectus supplement or term sheet as published in H.15 under the caption “U.S. government securities/treasury bills/secondary market” or, if not yet published by 3:00 p.m., New York City time, on the related calculation date, the rate on such Treasury Rate Interest Determination Date of such treasury bills as published in H.15, or such other recognized electronic source used for the purpose of displaying such rate, under the caption “U.S. government securities/treasury bills (secondary market).” If such rate is not yet published in H.15 or another recognized electronic source by 3:00 p.m., New York City time, on the related calculation date, then the Treasury Rate on such Treasury Rate Interest Determination Date shall be calculated by the calculation agent and shall be the bond equivalent yield of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 p.m., New York City time, on such Treasury Rate Interest Determination Date, of the three leading primary United States government securities dealers (which may include the agents or their affiliates) selected by the calculation agent (after consultation with us), for the issue of Treasury bills with a remaining maturity closest to the Index Maturity specified in the applicable prospectus supplement or term sheet; provided, however, that if the dealers so selected by the calculation agent are not quoting as mentioned in this sentence, the Treasury Rate determined as of such Treasury Rate Interest Determination Date will be the Treasury Rate in effect on such Treasury Rate Interest Determination Date.

The “bond equivalent yield” means a yield (expressed as a percentage) calculated in accordance with the following formula:

23

24

25

Eleventh District Cost of Funds Rate Notes. The “Eleventh District Cost of Funds Rate” for any Interest Determination Date is the rate equal to the monthly weighted average cost of funds for the calendar month preceding the Interest Determination Date as displayed on Reuters Page COFI/ARMS (or any other page as may replace that specified page on that service) as of 11:00 a.m., San Francisco time, on the Calculation Date for that Interest Determination Date under the caption “11th District.”

The following procedures will be used if the Eleventh District Cost of Funds Rate cannot be determined as described above:

Indexed Notes

We may issue debt securities for which the amount of interest or principal that you will receive will not be known on your date of purchase. Interest or principal payments for these types of debt securities, which we call “Indexed Notes,” are determined by reference to securities, financial or non-financial indices, currencies, commodities, interest rates, or a composite or baskets of any or all of the above. Examples of indexed items that may be used include a published stock index, the common stock price of a publicly traded company, the value of the U.S. dollar versus the Japanese yen, or the price of a barrel of West Texas intermediate crude oil.

If you purchase an Indexed Note, you may receive a principal amount at maturity that is greater than or less than the Note’s face amount, and an interest rate that is greater than or less than the interest rate that you would have earned if you had instead purchased a conventional debt security issued by us at the same time with the same maturity. The amount of interest and principal that you will receive will depend on the structure of the Indexed Note and the level of the specified indexed item throughout the term of the Indexed Note and at maturity. Specific information pertaining to the method of determining the interest payments and the principal amount will be described in the prospectus supplement or term sheet, as well as additional risk factors unique to the Indexed Note, certain historical information for the specified indexed item and certain additional United States federal income tax considerations.

Certain Covenants

General

The indenture contains certain covenants for the benefit of the holders of our debt securities, including, among other things, a covenant to maintain our corporate existence. In addition, the indenture contains the covenants

26

described in the two succeeding subsections, which may not apply to any series of subordinated debt securities issued under the indenture. Capitalized terms used in the following summary have the meanings specified in the indenture, unless otherwise defined below.

Limitation on Liens and Other Encumbrances

We have agreed that neither we nor any Restricted Subsidiary (as defined below) will incur, issue, assume or guarantee any Indebtedness secured by any Lien (as defined below) upon any Principal Property (as defined below) or shares of capital stock or indebtedness of any Restricted Subsidiary without securing the debt securities equally and ratably with all other Indebtedness secured by the Lien. This covenant has exceptions, which permit:

27

Notwithstanding the foregoing, we and any one or more of our Restricted Subsidiaries may issue, assume or guarantee Indebtedness secured by a Lien that would otherwise be subject to the foregoing restrictions if at the time of incurrence (the “Incurrence Time”), the amount equal to the sum of:

does not exceed 15% of our Consolidated Net Tangible Assets (as defined below).

“Attributable Debt” means, in respect of a Sale and Leaseback Transaction and as of any particular time, the present value of the obligation of the lessee thereunder for net rental payments during the remaining term of such lease, including any extensions. The present value of the obligation of the lessee is discounted at the rate of interest implicit in the terms of the lease involved in the Sale and Leaseback Transaction, as determined in good faith by us. Net rental payments exclude any amounts required to be paid by the lessee, whether or not designated as rent or additional rent, on account of maintenance and repairs, services, insurance, taxes, assessments, water rates or similar charges or any amounts required to be paid by the lessee, subject to monetary inflation or the amount of sales, maintenance and repairs, insurance, taxes, assessments, water rates or similar charges.

“Consolidated Net Tangible Assets” means the aggregate amount of assets after deducting the following:

28

“Indebtedness” means, with respect to any Person on any date of determination, without duplication:

provided, however, that Indebtedness shall not include any indebtedness of a subsidiary to the Company or another subsidiary.

“Lien” means any mortgage, lien, pledge, charge of any kind (including any conditional sale or other title retention agreement or lease in the nature thereof), security interest or other encumbrance.

“Principal Property” means all real and tangible personal property owned or leased by the Company or any Restricted Subsidiary constituting a part of any manufacturing or processing plant or warehouse located within the United States, exclusive of (1) motor vehicles and other rolling stock, (2) office furnishings and equipment, and information and electronic data processing equipment, (3) any property financed through the issuance of tax-exempt industrial development bonds, (4) any real property held for development or sale, or (5) any property which in the opinion of our board of directors as evidenced by a resolution of the board of directors is not of material importance to the total business conducted by Albemarle and its Restricted Subsidiaries as an entirety.

“Restricted Subsidiary” means any of our subsidiaries (a) substantially all of whose property is located within the United States and (b) which owns a Principal Property or in which our investment exceeds 1% of the aggregate amount of assets included on our consolidated balance sheet as of the end of the last fiscal quarter for which financial information is available.

“Sale and Leaseback Transaction” means any arrangement involving any bank, insurance company, or other lender or investor (in each case that is not the Company or an affiliate of the Company) or to which any such lender or investor is a party that provides for the lease by us or one of our Restricted Subsidiaries for a period, including renewals, in excess of three years of any Principal Property which has been or is to be sold or transferred by us or any Restricted Subsidiary to the lender or investor or to any Person to whom funds have been or are to be advanced by such lender or investor on the security of the Principal Property.

29

Restrictions on Sale and Leaseback Transactions

We have agreed not to, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction, unless:

Notwithstanding the foregoing, we and our Restricted Subsidiaries, or any of us, may enter into a Sale and Leaseback Transaction that would otherwise be prohibited as set forth above, if either:

does not at the time exceed 15% of our Consolidated Net Tangible Assets.

“Funded Debt” means: (a) all Indebtedness maturing one year or more from the date of its creation, (b) all Indebtedness directly or indirectly renewable or extendible, at the option of the debtor, by its terms or by the terms of the instrument or agreement relating thereto, to a date one year or more from the date of its creation, and (c) all Indebtedness under a revolving credit or similar agreement obligating the lender or lenders to extend credit over a period of one year or more.

Except for the limitations on Liens and other encumbrances and Sale and Leaseback Transactions described above, each of which may not apply to subordinated debt securities, and except as otherwise provided in a prospectus supplement, the indenture and the debt securities do not contain any covenants or other provisions designed to afford holders of the debt securities protection in the event of a highly leveraged transaction involving the Company.

Consolidation, Merger and Sale of Assets

We are generally permitted to consolidate or merge with another company. We are also permitted to sell or lease all or substantially all of our properties and assets to another company. However, we may not take any of these actions unless:

30

For the purposes of this provision, 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 the Company, which properties and assets, if held by the Company instead of such subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The indenture’s provisions regarding our consolidation, merger and sale or lease of assets, as described above, include a phrase relating to the conveyance, transfer or lease of “all or substantially all” of our properties and assets. 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, the applicability of the foregoing provisions in the case of a sale of such assets or properties may be uncertain.

Modification and Waiver

There are three types of changes we can make to the indenture and the debt securities issued under the indenture.

Changes Requiring Your Approval. First, there are changes that cannot be made to your debt securities without the approval of each holder affected thereby. Following is a list of those types of changes:

Changes Requiring a Majority Vote. The second type of change to the indenture or any supplement thereto and the debt securities is the kind that requires a vote in favor by holders of a majority of the outstanding debt

31

securities affected by the change. Most other changes fall into this category, except for changes noted above as requiring the approval of the holders of each security affected thereby, and, as noted below, waivers and changes not requiring any approval.

We would need a vote by holders of senior debt securities owning a majority of the principal amount of all series affected by the waiver, to obtain a waiver of certain of the restrictive covenants, including the covenants described above under “—Certain Covenants—Limitation on Liens and Other Encumbrances” and “—Certain Covenants—Restrictions on Sale and Leaseback Transactions.” We also need holders of senior debt securities or subordinated debt securities owning a majority of the principal amount of the relevant affected series to obtain a waiver of any past default with respect to such series, except a payment default listed in the first or second category described below under “—Default and Related Matters—Events of Default—What Is an Event of Default?”

The indenture provides that a supplemental indenture that changes or eliminates any covenant or other provision of the indenture that has expressly been included solely for the benefit of one or more particular series of securities, or that modifies the rights of the holders of securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the indenture of the holders of securities of any other series.

Changes Not Requiring Approval. The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would benefit or would not adversely affect holders of the debt securities.

Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a debt security:

Debt securities will not be considered outstanding, and therefore will not be eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption or if they have been fully defeased, as described under “Defeasance—Legal Defeasance.” Debt securities owned by us or any of our affiliates will also not be considered outstanding or eligible to vote.

If we determine to set a record date, we will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding debt securities of any series that are entitled to vote or take other action under the indenture. In some circumstances, the trustee will be entitled to set a record date for action by holders. If the trustee sets a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by Persons who are holders of outstanding securities of that series on the record date and the action voted upon must be effective within 90 days following the record date.

Indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change an indenture or the debt securities or request a waiver.

Satisfaction and Discharge

The following discussion of satisfaction and discharge provisions will be applicable to your series of debt securities unless the applicable prospectus supplement states that they will not apply to that series.

32

We can satisfy our obligations under our outstanding debt securities of any series and the indenture will cease to be of further effect (with limited exceptions) if we put in place the following arrangements for you to be repaid:

Defeasance

The following discussion of legal defeasance and covenant defeasance provisions will be applicable to your series of debt securities unless the applicable prospectus supplement states that they will not apply to that series.

Legal Defeasance

If there is a change in federal income tax law, as described below, we can legally release ourselves from any payment or other obligations, with certain limited exceptions, on any series of debt securities, called legal defeasance, if we put in place the following arrangements for you to be repaid:

33

There must be a change in current federal income tax law or a U.S. Internal Revenue Service ruling that lets us make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities at maturity or redemption.

In the event of legal defeasance, you would have to rely solely on the trust holding the deposited cash and/or U.S. government notes or bonds for repayment of the debt securities. In addition, in the case of subordinated debt securities, the relevant subordination provisions would not apply. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

Covenant Defeasance

Under current federal income tax law, we can make the same type of deposit described above under “—Defeasance—Legal Defeasance” and be released from some of the restrictive covenants in the debt securities. This is called covenant defeasance. In that event, you would lose the protection of those restrictive covenants but would gain the protection of having cash and/or U.S. government notes or bonds set aside in trust to repay the debt securities. In order to achieve covenant defeasance, we must do the following:

34

If we accomplish covenant defeasance, the following provisions, among others, of the indenture and the debt securities would no longer apply:

In addition, in the case of subordinated debt securities, the relevant subordination provisions would not apply if we accomplish covenant defeasance.

If we accomplish covenant defeasance, you could still look to us for repayment of the debt securities if there were a shortfall in the trust. In fact, if one of the remaining events of default occurs, such as our bankruptcy, and the debt securities become immediately due and payable, there may be a shortfall in the trust.

Default and Related Matters

Events of Default

You will have special rights if an event of default occurs and is not cured, as described later in this subsection.

What Is an Event of Default? The term “event of default” means, with respect to any series of debt securities, any of the following:

35

“Significant Subsidiary” means any of our subsidiaries that would be a “Significant Subsidiary” of the Company within the meaning of Rule 1-02 under Regulation S-X promulgated by the SEC.

Remedies if an Event of Default Occurs. If you are the holder of a subordinated debt security, all remedies available upon the occurrence of an event of default under the indenture will be subject to the restrictions on the subordinated debt securities described in the applicable prospectus supplement. If an event of default has occurred and has not been cured, the trustee or the holders of 25% in aggregate principal amount of the outstanding debt securities of the affected series may declare the entire principal amount (or, in the case of original issue discount debt securities, the portion of the principal amount that is specified in the terms of the affected debt security) of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. If, however, we or any Significant Subsidiary files for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur, all of the debt securities of the affected series shall become immediately due and payable without any declaration of acceleration of maturity or any other action on the part of the trustee or the holders of the debt securities of the affected series. After any such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of such series may, under certain circumstances, rescind and annul such acceleration and its consequences if all events of default in respect of such series, other than the non-payment of accelerated principal (or other specified amount), have been cured or waived as provided in the indenture and certain other conditions are met. See “—Modification and Waiver.”

Reference is made to the prospectus supplement relating to any series of debt securities that are original issue discount debt securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount debt securities upon the occurrence of an event of default and its continuation.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection satisfactory to the trustee from expenses and liability, called an indemnity. If such indemnity is provided, the holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the indenture with respect to the debt securities of that series. The trustee may withhold notice of any default, except a default in the payment of principal or interest, from the holders of any series of debt securities if the trustee in good faith considers it to be in the interest of holders to do so.

No holder of any debt securities may institute any action under the indenture unless:

36

However, you are entitled at any time to bring a lawsuit for the payment of money due on your debt security on or after its due date.

Street name and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration.

We will furnish to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities issued under it, or else specifying any default or event of default and its status.

Notices

We and the trustee will send notices regarding the debt securities only to holders at their addresses as listed in the records of the security registrar.

Governing Law

The indenture and the debt securities are governed by, and construed in accordance with, the laws of the State of New York.

Legal Ownership

Global Securities

What Is a Global Security? A global security is a special type of indirectly held security, as described below under “—Indirect Holders.”

If we choose to issue debt securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. We do this by requiring that the global security be registered in the name of a financial institution we select and by requiring that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described below occur. The financial institution that acts as the sole direct holder of the global security is called the depositary. Unless otherwise stated in the applicable prospectus supplement, the debt securities of a series issued in the form of global securities will be deposited with The Depository Trust Company (“DTC”), which will act as depositary for the global securities.

Any Person wishing to own a debt security included in the global security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary. The prospectus supplement will indicate whether your series of debt securities will initially be issued only in the form of global securities.

Special Investor Considerations for Global Securities. As an indirect holder, an investor’s rights relating to a global security will be governed by the account rules of the investor’s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize this type of investor as a registered holder of debt securities and instead deal only with the depositary that holds the global security.

37

If you are an investor in debt securities that are issued only in the form of global securities, you should be aware that generally:

Special Situations When a Global Security Will Be Exchanged For Physical Certificates. In a few special situations described below, interests in the global security will be exchanged for physical certificates representing debt securities. After that exchange, the choice of whether to hold debt securities directly or indirectly will be up to you. You must consult your own bank or broker to find out how to have your interests in debt securities transferred to your own name, so that you will be a direct holder. The rights of direct and indirect holders in the debt securities are described below under “—Direct Holders” and “—Indirect Holders.”

The special situations when a global security may be exchanged for physical certificates are:

Defaults are discussed above under “—Default and Related Matters.”

The prospectus supplement may also list additional situations when a global security may be exchanged for physical certificates that would apply only to the particular series of debt securities covered by that prospectus supplement. When physical certificates are to be exchanged for a global security, the depositary (and not we or the trustee) is responsible for deciding the names of the institutions that will be the initial direct holders of the physical certificates.

Direct Holders

Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, are only to Persons or entities who are the direct holders of debt securities (i.e., those who are registered as holders of debt securities). As noted below, we do not have obligations to you if you hold through indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described above. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that registered holder is legally required to pass the payment along to you as a street name customer but does not do so.

38

Indirect Holders

Investors who hold debt securities in accounts at banks or brokers will not be recognized by us as legal holders of debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. If you hold debt securities in street name, you should check with your own institution to find out:

39

DESCRIPTION OF DEBT WARRANTS

We may issue (either separately or together with other offered securities) debt warrants to purchase underlying debt securities issued by us (“offered debt warrants”). We will issue the debt warrants under warrant agreements (each a “debt warrant agreement”) to be entered into between us and a bank or trust company, as warrant agent (the “debt warrant agent”), identified in the prospectus supplement or term sheet. In this “Description of Debt Warrants” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries.

Because this section is a summary, it does not describe every aspect of the debt warrants and the debt warrant agreement. We urge you to read the debt warrant agreement because it, and not this description, defines your rights as a holder of debt warrants. We will file the form of debt warrant agreement with the SEC. See “Where You Can Find More Information” for information on how to obtain a copy of the debt warrant agreement.

General

You should read the prospectus supplement or term sheet for the material terms of the offered debt warrants, including the following:

The prospectus supplement or term sheet will also contain a discussion of the United States federal income tax considerations relevant to the offering.

Debt warrant certificates will be exchangeable for new debt warrant certificates of different denominations. No service charge will be imposed for any permitted transfer or exchange of debt warrant certificates, but we may require payment of any tax or other governmental charge payable in connection therewith. Debt warrants may be exercised and exchanged and debt warrants in registered form may be presented for registration of transfer at the corporate trust office of the debt warrant agent or any other office indicated in the prospectus supplement or term sheet.

Exercise of Debt Warrants

Each offered debt warrant will entitle the holder thereof to purchase the amount of underlying debt securities at the exercise price set forth in, or calculable from, the prospectus supplement or term sheet relating to the offered debt warrants. After the close of business on the expiration date, unexercised debt warrants will be void.

40

Debt warrants may be exercised by payment to the debt warrant agent of the applicable exercise price and by delivery to the debt warrant agent of the related debt warrant certificate, properly completed. Debt warrants will be deemed to have been exercised upon receipt of the exercise price and the debt warrant certificate or certificates.

Upon receipt of this payment and the properly completed debt warrant certificates, we will, as soon as practicable, deliver the amount of underlying debt securities purchased upon exercise.

If fewer than all of the debt warrants represented by any debt warrant certificate are exercised, a new debt warrant certificate will be issued for the unexercised debt warrants. The holder of a debt warrant will be required to pay any tax or other governmental charge that may be imposed in connection with any transfer involved in the issuance of underlying debt securities purchased upon exercise.

Modifications

There are three types of changes we can make to a debt warrant agreement and the debt warrants issued thereunder.

Changes Requiring Your Approval. First, there are changes that cannot be made to your debt warrants without your specific approval. Those types of changes include modifications and amendments that:

Changes Not Requiring Approval. The second type of change does not require any vote by holders of the debt warrants. This type of change is limited to clarifications and other changes that would not materially adversely affect the interests of holders of the debt warrants.

Changes Requiring a Majority Vote. Any other change to the debt warrant agreement and the debt warrants requires a vote in favor by holders of a majority in number of the then outstanding unexercised debt warrants affected thereby. Most changes fall into this category.

No Rights as Holders of Underlying Debt Securities

Before the warrants are exercised, holders of the debt warrants are not entitled to payments of principal, premium or interest, if any, on the related underlying debt securities or to exercise any rights whatsoever as holders of the underlying debt securities.

41

DESCRIPTION OF COMMON WARRANTS

We may issue (either separately or together with other offered securities) common warrants. We will issue the common warrants under warrant agreements (each, a “common warrant agreement”) to be entered into between us and a bank or trust company, as warrant agent (the “common warrant agent”), identified in the prospectus supplement or term sheet. In this “Description of Common Warrants” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries.

Because this section is a summary, it does not describe every aspect of the common warrants and common warrant agreement.

General

You should read the prospectus supplement or term sheet for the material terms of the offered common warrants, including the following:

The prospectus supplement or term sheet will also contain a discussion of the United States federal income tax considerations relevant to the offering.

Certificates representing common warrants will be exchangeable for new common warrant certificates of different denominations. We will not impose a service charge for any permitted transfer or exchange of common warrant certificates, but we may require payment of any tax or other governmental charge payable in connection therewith. Common warrants may be exercised at the corporate trust office of the common warrant agent or any other office indicated in the prospectus supplement or term sheet.

Exercise of Common Warrants

Each offered common warrant will entitle the holder thereof to purchase the number of shares of common stock at the exercise price set forth in, or calculable from, the prospectus supplement or term sheet relating to the common warrants. After the close of business on the applicable expiration date, unexercised common warrants will be void.

Common warrants may be exercised by payment to the common warrant agent of the exercise price and by delivery to the common warrant agent of the related common warrant certificate, with the reverse side thereof

42

properly completed. Common warrants will be deemed to have been exercised upon receipt of the exercise price and the common warrant certificate or certificates. Upon receipt of the payment and the properly completed common warrant certificates, we will, as soon as practicable, deliver the shares of common stock purchased upon the exercise.

If fewer than all of the common warrants represented by any common warrant certificate are exercised, a new common warrant certificate will be issued for the unexercised offered common warrants. The holder of an offered common warrant will be required to pay any tax or other governmental charge that may be imposed in connection with any transfer involved in the issuance of common stock purchased upon exercise.

Modifications

There are three types of changes we can make to a common warrant agreement and the common warrants issued thereunder.

Changes Requiring Your Approval. First, there are changes that cannot be made to your common warrants without your specific approval. Those types of changes include modifications and amendments that:

Changes Not Requiring Approval. The second type of change does not require any vote by holders of the common warrants. This type of change is limited to clarifications and other changes that would not materially adversely affect the interests of the holders of the common warrants.

Changes Requiring a Majority Vote. Any other change to the common warrant agreement requires a vote in favor by holders of not fewer than a majority in number of the then outstanding unexercised common warrants affected thereby. Most changes fall into this category.

Common Warrant Adjustments

The terms and conditions on which the exercise price of and/or the number of shares of common stock covered by a common warrant are subject to adjustment will be set forth in the common warrant agreement and the prospectus supplement or term sheet. The terms will include provisions for adjusting the exercise price and/or the number of shares of common stock covered by the common warrant; the events requiring the adjustment; the events upon which we may, in lieu of making the adjustment, make proper provisions so that the holder of a common warrant, upon exercise thereof, would be treated as if the holder had exercised the common warrant prior to the occurrence of the events; and provisions affecting exercise in the event of certain events affecting the common stock.

No Rights as Shareholders

Holders of common warrants are not entitled, by virtue of being holders, to receive dividends or to vote, consent or receive notice as our shareholders in respect of any meeting of shareholders for the election of our directors or for any other matter, or exercise any other rights whatsoever as our shareholders.

43

DESCRIPTION OF UNITS

Albemarle Corporation may issue units that will represent an interest in one or more debt securities, preferred stock, common stock, debt warrants, common warrants as well as debt or equity securities of third parties, in any combination, which may or may not be separable from one another. Each unit will be issued under a unit agreement or indenture. Albemarle Corporation will set forth in the applicable prospectus supplement a description of any units issued by it that may be offered pursuant to this prospectus.

SPECIAL PROVISIONS RELATING TO FOREIGN CURRENCY DEBT SECURITIES

General

Unless otherwise indicated in the applicable prospectus supplement or term sheet, the debt securities will be denominated in U.S. dollars, payments of principal of, premium, if any, and interest on the debt securities will be made in U.S. dollars and payment of the purchase price of the debt securities must be made in immediately available funds. If any of the debt securities (“Foreign Currency Debt Securities”) are to be denominated or payable in a currency (a “specified currency”) other than U.S. dollars, the following provisions will apply in addition to, and to the extent inconsistent therewith will replace, the description of general terms and provisions of debt securities set forth elsewhere in this prospectus. In this “Special Provisions Relating to Foreign Currency Debt Securities” section, references to “Albemarle,” “the Company,” “we,” “our” or “us” are only to Albemarle Corporation and not its subsidiaries.

A prospectus supplement or term sheet with respect to any Foreign Currency Debt Security (which may include information with respect to applicable current foreign exchange controls) is a part of this prospectus and prospectus supplement or term sheet. Any information concerning exchange rates is furnished as a matter of information only and should not be regarded as indicative of the range of or trends in fluctuations in currency exchange rates that may occur in the future.

Currencies

We may offer Foreign Currency Debt Securities denominated and/or payable in a specified currency or specified currencies. Unless otherwise indicated in the applicable prospectus supplement or term sheet, purchasers are required to pay for Foreign Currency Debt Securities in the specified currency. At the present time, there are limited facilities in the United States for conversion of U.S. dollars into specified currencies and vice versa, and banks may elect not to offer non-U.S. dollar checking or savings account facilities in the United States. However, if requested on or prior to the fifth Business Day preceding the date of delivery of the Foreign Currency Debt Securities, or by such other day as determined by the agent who presents such offer to purchase Foreign Currency Debt Securities to us, such agent may be prepared to arrange for the conversion of U.S. dollars into the specified currency set forth in the applicable prospectus supplement or term sheet to enable the purchasers to pay for the Foreign Currency Debt Securities. Each such conversion will be made by the agents on such terms and subject to such conditions, limitations and charges as the agents may from time to time establish in accordance with their regular foreign exchange practices. All costs of exchange will be borne by the purchasers of the Foreign Currency Debt Securities.

Information about the specified currency in which a particular Foreign Currency Debt Security is denominated and/or payable, including historical exchange rates and a description of the currency and any exchange controls, will be set forth in the applicable prospectus supplement or term sheet.

Payment of Principal and Interest

The principal of, premium, if any, and interest on Foreign Currency Debt Securities are payable by us in the specified currency. Currently, banks do not generally offer non-U.S. dollar-denominated account facilities in

44

their offices in the United States, although they are permitted to do so. Accordingly, a holder of Foreign Currency Debt Securities will be paid in U.S. dollars converted from the specified currency unless the holder is entitled to elect, and does elect, to be paid in the specified currency, or as otherwise specified in the applicable prospectus supplement or term sheet.

Any U.S. dollar amount to be received by a holder of a Foreign Currency Debt Security will be based on the highest bid quotation in The City of New York received by an agent for us specified in the applicable prospectus supplement or term sheet (the “Exchange Rate Agent”) at approximately 11:00 A.M., New York City time, on the second Business Day preceding the applicable payment date from three recognized foreign exchange dealers (one of whom may be the Exchange Rate Agent) selected by the Exchange Rate Agent and approved by us for the purchase by the quoting dealer of the specified currency for U.S. dollars for settlement on the payment date in the aggregate amount of the specified currency payable to all holders of Foreign Currency Debt Securities scheduled to receive U.S. dollar payments and at which the applicable dealer commits to execute a contract. If three bid quotations are not available, payments will be made in the specified currency. All currency exchange costs will be borne by the holder of the Foreign Currency Debt Security by deductions from such payments.

Unless otherwise indicated in the applicable prospectus supplement or term sheet, a holder of Foreign Currency Debt Securities may elect to receive payment of the principal of, and premium, if any, and interest on the Foreign Currency Debt Securities in the specified currency by transmitting a written request for such payment to the corporate trust office of the trustee in The City of New York on or prior to the regular record date or at least fifteen calendar days prior to Maturity Date, as the case may be. This request may be in writing (mailed or hand delivered) or sent by cable, telex or other form of facsimile transmission. A holder of a Foreign Currency Debt Security may elect to receive payment in the specified currency for all principal, premium, if any, and interest payments and need not file a separate election for each payment. This election will remain in effect until revoked by written notice to the trustee, but written notice of any revocation must be received by the trustee on or prior to the regular record date or at least fifteen calendar days prior to the Maturity Date, as the case may be. Holders of Foreign Currency Debt Securities whose debt securities are to be held in the name of a broker or nominee should contact their brokers or nominees to determine whether and how an election to receive payments in the specified currency may be made.

Unless otherwise specified in the applicable prospectus supplement or term sheet, if the specified currency is other than U.S. dollars, a beneficial owner of the related global security who elects to receive payments of principal, premium, if any, and/or interest, if any, in the specified currency must notify its participant through which it owns its beneficial interest on or prior to the applicable record date or at least fifteen calendar days prior to the Maturity Date, as the case may be, of such beneficial owner’s election. The participant must notify the depositary of such election on or prior to the third Business Day after such record date or at least 12 calendar days prior to the Maturity Date, as the case may be, and the depositary will notify the trustee of such election on or prior to the fifth Business Day after such record date or at least ten calendar days prior to the Maturity Date, as the case may be. If complete instructions are received by the participant from the beneficial owner and forwarded by the participant to the depositary, and by the depositary to the trustee, on or prior to such dates, then the beneficial owner will receive payments in the specified currency. See “Description of Debt Securities—Legal Ownership.”

Principal and interest on Foreign Currency Debt Securities paid in U.S. dollars will be paid in the manner specified in the accompanying prospectus supplement or term sheet and this prospectus with respect to debt securities denominated in U.S. dollars. Interest on Foreign Currency Debt Securities paid in the specified currency will be paid by us in immediately available funds or paid by check mailed on an Interest Payment Date other than a Maturity Date to the persons entitled thereto to the addresses of such holders as they appear in the security register or, at our option, by wire transfer to a bank account maintained by the holder in the country of the specified currency. The principal of, premium, if any, and interest on Foreign Currency Debt Securities, together with interest accrued and unpaid thereon, due on the Maturity Date will be paid, in the specified currency in immediately available funds upon surrender of such debt securities at the corporate trust office of the

45

trustee in The City of New York, or, at our option, by wire transfer to such bank account of immediately available funds to an account with a bank designated at least 15 calendar days prior to the Maturity Date by the applicable registered holder, provided the particular bank has appropriate facilities to make these payments and the particular Foreign Currency Debt Security is presented and surrendered at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, in time for the trustee to make these payments in accordance with its normal procedures.

Payment Currency

If a specified currency is not available for the payment of principal, premium or interest with respect to a Foreign Currency Debt Security due to the imposition of exchange controls or other circumstances beyond our control, we will be entitled to satisfy our obligations to holders of Foreign Currency Debt Securities by making such payment in U.S. dollars on the basis of the noon buying rate in The City of New York for cable transfers of the specified currency as certified for customs purposes (or, if not so certified, as otherwise determined) by the Federal Reserve Bank of New York (the “Market Exchange Rate”) as computed by the Exchange Rate Agent on the second Business Day prior to such payment or, if not then available, on the basis of the most recently available Market Exchange Rate or as otherwise indicated in an applicable prospectus supplement or term sheet. Any payment made under these circumstances in U.S. dollars where the required payment is in a specified currency will not constitute a default under the Indenture with respect to the Debt Securities.

All determinations referred to above made by the Exchange Rate Agent will be at its sole discretion and will, in the absence of manifest error, be conclusive for all purposes and binding on the holders of the Foreign Currency Debt Securities.

AS INDICATED ABOVE, AN INVESTMENT IN FOREIGN CURRENCY DEBT SECURITIES INVOLVES SUBSTANTIAL RISKS, AND THE EXTENT AND NATURE OF SUCH RISKS CHANGE CONTINUOUSLY. AS WITH ANY INVESTMENT IN A SECURITY, PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL ADVISORS AS TO THE RISKS ENTAILED IN AN INVESTMENT IN FOREIGN CURRENCY DEBT SECURITIES. SUCH DEBT SECURITIES ARE NOT AN APPROPRIATE INVESTMENT FOR PROSPECTIVE PURCHASERS WHO ARE UNSOPHISTICATED WITH RESPECT TO FOREIGN CURRENCY MATTERS.

46

PLAN OF DISTRIBUTION

We may sell the offered securities:

Any underwriters or agents will be identified and their discounts, commissions and other items constituting underwriters’ compensation and any securities exchanges on which the securities are listed will be described in the applicable prospectus supplement or term sheet.

We (directly or through agents) may sell, and the underwriters may resell, the offered securities in one or more transactions, including negotiated transactions, at a fixed public offering price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.

In order to facilitate the offering of the debt securities, the underwriters or agents may engage in transactions that stabilize, maintain or otherwise affect the price of the debt securities and our common stock. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters or agents of a greater number of debt securities than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ or agents’ option to purchase additional debt securities from us in the offering. The underwriters or agents may close out any covered short position by either exercising the option to purchase additional debt securities or purchasing debt securities in the open market. In determining the source of debt securities to close out the covered short position, the underwriters or agents will consider, among other things, the price of debt securities available for purchase in the open market as compared to the price at which they may purchase debt securities through the option. “Naked” short sales are sales in excess of the option. The underwriters or agents must close out any naked short position by purchasing debt securities in open market. A naked short position is more likely to be created if the underwriters or agents are concerned that there may be a downward pressure on the price of the debt securities in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of certain bids for or purchases of the debt securities made by the underwriters or agents in the open market prior to the completion of the offering. Any of these activities may stabilize or maintain the market price of the debt securities above independent market levels. The underwriters or agents are not required to engage in these activities, and may end any of these activities at any time.

In connection with the sale of offered securities, the underwriters or agents may receive compensation from us or from purchasers of the offered securities for whom they may act as agents. The underwriters may sell offered securities to or through dealers, who may also receive compensation from purchasers of the offered securities for whom they may act as agents. Compensation may be in the form of discounts, concessions or commissions. Underwriters, dealers and agents that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act, and any discounts or commissions received by them from us and any profit on the resale of the offered securities by them may be treated as underwriting discounts and commissions under the Securities Act.

We will indemnify the underwriters and agents against certain civil liabilities, including liabilities under the Securities Act, or contribute to payments they may be required to make in respect of such liabilities.

Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our affiliates in the ordinary course of their businesses.

47

If so indicated in the prospectus supplement or term sheet relating to a particular series or issue of offered securities, we will authorize underwriters, dealers or agents to solicit offers by certain institutions to purchase the offered securities from us under delayed delivery contracts providing for payment and delivery at a future date. These contracts will be subject only to those conditions set forth in the prospectus supplement or term sheet, and the prospectus supplement or term sheet will set forth the commission payable for solicitation of these contracts.

In connection with the distribution of the offered securities or otherwise, we may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our securities in the course of hedging the positions they assume with us. We may also sell offered securities short and deliver the securities offered by this prospectus to close out our short positions. We may also enter into option or other transactions with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus, as supplemented or amended to reflect such transaction. We may also from time to time pledge our offered securities pursuant to the margin provisions of our customer agreements with our brokers. Upon our default, the broker may offer and sell such pledged securities from time to time pursuant to this prospectus, as supplemented or amended to reflect such transaction.

Unless otherwise indicated in your prospectus supplement or confirmation of sale, the purchase price of the securities will be required to be paid in immediately available funds in New York City.

48

LEGAL MATTERS

The validity of the securities offered hereby and certain other legal matters will be passed upon for us by Shearman & Sterling LLP, New York, New York, and/or Hunton Andrews Kurth LLP, Richmond, Virginia.
