INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS

We make “forward-looking statements” within the “safe harbor” provision of the Private Securities Litigation Reform Act of 1995, as amended, throughout this prospectus supplement, the accompanying prospectus and in the documents we incorporate by reference into this prospectus supplement and the accompanying prospectus, including those relating to the potential effects of the COVID-19 pandemic (“COVID-19”) on the Company’s business, operations, financial performance and prospects. You can identify these statements by forward-looking words such as “may,” “will,” “should,” “expect,” “anticipate,” “believe,” “intend,” “estimate,” “plan” and “continue” or similar words. We have based these statements on our current expectations about potential future events. Although we believe the expectations expressed in the forward-

S-iv

looking statements included in this prospectus supplement and the accompanying prospectus and those reports, statements, information and announcements incorporated by reference into this prospectus supplement and the accompanying prospectus are based upon reasonable assumptions within the bounds of our knowledge of our business, a number of factors could cause actual results to differ materially from those expressed in any forward-looking statements, whether oral or written, made by us or on our behalf. Further, statements about the effects of COVID-19 on our business, operations, financial performance and prospects may constitute forward-looking statements and are subject to the risk that the actual impacts may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including the scope and duration of COVID-19, actions taken by governmental authorities in response to COVID-19, and the direct and indirect impact of COVID-19 on our customers, insurance carriers, third parties and us. Many of these factors have previously been identified in filings or statements made by us or on our behalf. Important factors which could cause our actual results to differ materially from the forward-looking statements in this prospectus include, but are not limited to, the following items:

S-v

For a further list and description of various risks, relevant factors and uncertainties that could cause future results or events to differ materially from those expressed or implied in our forward-looking statements, see the “Risk Factors” section contained herein and in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section contained in the documents incorporated by reference in this prospectus supplement.

S-vi

Assumptions as to any of the foregoing and all statements are not based upon historical fact, but rather reflect our current expectations concerning future results and events. Forward-looking statements that we make or that are made by others on our behalf are based upon a knowledge of our business and the environment in which we operate, but because of the factors listed above, among others, actual results may differ from those in the forward-looking statements. Consequently, these cautionary statements qualify all of the forward-looking statements we make herein. We cannot assure you that the results or developments anticipated by us will be realized or, even if substantially realized, that those results or developments will result in the expected consequences for us or affect us, our business or our operations in the way we expect. We caution readers not to place undue reliance on these forward-looking statements, which speak only as of their dates. We assume no obligation to update any of the forward-looking statements.

RISK FACTORS

Investing in the notes involves risk. The following risk factors, as well as those relating to our business under Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, Part II, Item 1A, “Risk Factors” in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020, and Part II, Item 1A, “Risk Factors” in our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020, which are incorporated herein by reference, should be considered prior to deciding to invest in any of the notes offered for sale pursuant to this prospectus supplement. These risk factors may be amended, supplemented or superseded from time to time by risk factors contained in Exchange Act reports that we file with the SEC, which will be incorporated herein by reference, or by a post-effective amendment to the registration statement of which this prospectus supplement forms a part. There may be additional risks that are not presently material or known. If any of the events described below occur, our business, financial condition, results of operations, liquidity or access to the debt or capital markets could be materially adversely affected. The following risks could cause our actual results to differ materially from our historical experience and from any estimates or expectations set forth in forward-looking statements made in or incorporated by reference into this prospectus supplement or the documents incorporated herein by reference. As used herein, “notes” refers to the notes offered hereby.

Risks Related to Our Business

The COVID-19 pandemic and the resulting governmental and societal responses, the severity and duration of the pandemic and the resulting impact on the U.S. economy and the global economy, may materially and adversely affect the Company’s business, liquidity, customers, insurance carriers and third parties.

In December 2019, a novel strain of coronavirus, COVID-19, surfaced. Since then, COVID-19 has spread across the world, and has been declared a pandemic by the World Health Organization. The global outbreak of COVID-19 continues to rapidly evolve. The COVID-19 pandemic has created significant volatility, uncertainty and economic disruption, which could adversely affect our business and may materially and adversely affect our financial condition, results of operations and cash flows. The extent to which COVID-19 impacts our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the ultimate geographic spread and severity of COVID-19; the duration of the pandemic; business closures, travel restrictions, social distancing and other actions taken to contain and treat COVID-19; the effectiveness of actions taken to contain and treat the virus; the impact of the pandemic on economic activity; the extent and duration of the effect on customer demand and buying patterns; and any impairment in value of our tangible or intangible assets which could be recorded as a result of a weaker economic conditions. In addition, if the pandemic continues to create disruptions or turmoil in the credit or financial markets, or impacts our credit ratings, it could adversely affect our ability to access capital on favorable terms and continue to meet our liquidity needs, all of which are highly uncertain and cannot be predicted.

As the COVID-19 pandemic and any associated protective or preventative measures continue to spread in the United States and around the world, we may experience disruptions to our business, including:

S-4

We cannot predict the impact that COVID-19 will have on our customers, insurance carriers, suppliers, and other third party contractors, and each of their financial conditions; however, any material effect on these parties could adversely impact us. Even after the COVID-19 outbreak has subsided, we may experience materially adverse impacts to our business as a result of the virus’ global economic impact. Further, COVID-19 may affect our operating and financial results in a manner that is not presently known to us or that we currently do not consider to present significant risks to our operations.

Additionally, COVID-19 could negatively affect our internal controls over financial reporting as a portion of our workforce is required to work from home and therefore new processes, procedures, and controls could be required to respond to changes in our business environment. Further, should any key employees become ill from the coronavirus and unable to work, the attention of the management team could be diverted. Our management is focused on mitigating the effects of COVID-19, which has required and will continue to require a large investment of time and resources across our business.

To mitigate the economic impact caused by COVID-19, certain governmental entities have declared or proposed a “grace period” on the collection of insurance premiums. It is unclear the impact this would have on our commission revenues, typically calculated as a percentage of premium. It is possible that such grace periods could delay our receipt of revenues as we continue to incur compensation and operating expenses related to serving our clients. In addition, certain governmental entities have proposed requiring underwriting enterprises to pay business interruption and workers’ compensation claims for COVID-19 losses despite applicable policy exclusions. Retroactively expanding business interruption or other coverages could materially negatively affect underwriting enterprises, reduce the availability of insurance coverage, and negatively affect our ability to generate commission revenues from such policies as well as supplemental and contingent commissions from underwriting enterprises. Other legislation under consideration would require underwriting enterprises to return premiums to clients on certain lines of coverage. While it is unclear the impact such legislation would have on us, it is possible we could be asked to disgorge commission revenues related to such premiums.

These and other disruptions related to COVID-19 could materially and adversely affect our business, financial condition, results of operations and cash flows. Further, the potential effects of COVID-19 also could impact many of our risk factors disclosed in Item 1A, “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. However, as the COVID-19 situation is unprecedented and continuously evolving, the potential impacts to our risk factors that are further described in our Annual Report on Form 10-K for the year ended December 31, 2019, remain uncertain.

Risks Related to the Notes

We may not be able to generate sufficient cash flow to service our obligations under the notes.

Our ability to service our obligations under the notes will depend upon, among other things, our revenues from commissions and fees and other factors that affect our future financial and operating performance, including, without limitation, prevailing economic conditions and financial, business and regulatory factors, many of which are beyond our control.

If we are unable to generate sufficient cash flow to service our obligations under the notes, we may be forced to take actions such as:

S-5

Such measures might not be successful and might not enable us to service our obligations under the notes. In addition, any such financing, refinancing or sale of assets might not be available on economically favorable terms or at all.

If we fail to comply with the covenants contained in certain of our agreements, our liquidity, results of operations and financial condition may be adversely affected.

On June 28, 2017, we entered into an amended and restated credit agreement with JPMorgan Chase Bank, N.A. as administrative agent and certain other banks as co-syndication agents and co-documentation agents, in the aggregate amount of $1,200.0 million (the “Credit Facility”). The Credit Facility provides for an unsecured revolving credit facility in the initial amount of $800.0 million and unsecured term loans in the initial amount of $400.0 million. The Credit Facility matures on June 28, 2022, but either or both of the revolving credit facility and/or the term loans under the Credit Facility may be extended for two additional one-year periods at our request, subject to the approval of the respective lenders and certain other conditions. As of June 30, 2020, we had $510.0 million outstanding under the Credit Facility, consisting of $310.0 million of outstanding term loans and $200.0 million under the revolving portion of the Credit Facility.

On December 21, 2018, we entered into a term loan credit agreement with Wells Fargo Bank, National Association, as administrative agent, and certain other banks as co-syndication agents and co-documentation agents (the “Term Loan Facility”, and together with the Credit Facility, the “Credit Agreements”). The Term Loan Facility provides for an unsecured term loan in the initial amount of $300.0 million, which may, subject to lenders’ discretion, potentially be increased up to an aggregate amount of $450.0 million (the “Term Loan”). The Term Loan is repayable over the five-year term from the effective date of the Term Loan Facility, which was December 21, 2018. Based on our net debt leverage ratio or a non-credit enhanced senior unsecured long-term debt rating as determined by Moody’s Investor Service and Standard & Poor’s Rating Service, the current rate of interest on the Term Loan is 1.25% above the adjusted 1-Month London Interbank Offered Rate (“LIBOR”). As of June 30, 2020, there was an outstanding debt balance issued under the Term Loan of $277.5 million.

Each of the Credit Agreements contains various covenants and other limitations with which we must comply. June 30, 2020, we were in compliance with the financial covenants and other limitations contained in each of the Credit Agreements. However, failure to comply with material provisions of our covenants in these Credit Agreements or other credit or similar agreements to which we may become a party could result in a default, rendering them unavailable to us and causing a material adverse effect on our liquidity, results of operations and financial condition. In the event of certain defaults under the Credit Agreements, the lenders thereunder would not be required to lend any additional amounts to or purchase any additional notes from us and could elect to declare all borrowings outstanding, together with accrued and unpaid interest and fees, to be due and payable. If the indebtedness under the Credit Agreements or our other indebtedness, including the notes, were to be accelerated, there can be no assurance that our assets would be sufficient to repay such indebtedness in full.

Certain of our agreements contain various covenants that limit the discretion of our management in operating our business and could prevent us from engaging in certain potentially beneficial activities.

The restrictive covenants in the Credit Agreements may impact how we operate our business and prevent us from engaging in certain potentially beneficial activities. In particular, among other covenants, the Credit Facility

S-6

requires us to maintain a ratio of consolidated EBITDA (earnings before interest, taxes, depreciation and amortization), adjusted for certain transaction-related items (“Consolidated EBITDA”), to consolidated interest expense and a ratio of consolidated net indebtedness to Consolidated EBITDA. The ratio of Consolidated EBITDA to consolidated interest expense must be at least 4.00 to 1.00, and the ratio of consolidated net indebtedness to Consolidated EBITDA must not exceed 3.25 to 1.00 (provided that we may, on not more than two occasions during the term of the Credit Facility, elect to increase such ratio to 3.75 to 1.00 for a period of six consecutive fiscal quarters in connection with and following certain significant acquisitions).

While neither the notes nor the indenture governing the notes includes similar covenants, our compliance with these covenants limits our management’s discretion in operating our business and could prevent us from engaging in certain potentially beneficial activities.

We may still be able to incur substantially more indebtedness. This could exacerbate the risks associated with our indebtedness under the notes.

We may be able to incur substantial additional indebtedness in the future, including secured debt. The terms of the indenture governing the notes offered hereby will not prevent us or our subsidiaries from incurring indebtedness, and the Credit Agreements do not prevent us or our subsidiaries from incurring indebtedness, subject to certain restrictive covenants in the Credit Agreements. If we incur any additional indebtedness that ranks equally with the notes offered hereby and the obligations under the Credit Agreements, the holders of that indebtedness will be entitled to share ratably with the holders of the notes offered hereby in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of us. This may have the effect of reducing the amount of proceeds paid to you.

The notes offered hereby will be unsecured and effectively subordinated to any future secured indebtedness and structurally subordinated to all of the liabilities of our subsidiaries.

We do not currently have any secured indebtedness. The notes offered hereby will be general unsecured obligations ranking effectively junior in right of payment to any future secured indebtedness to the extent of the value of the collateral securing the indebtedness. Additionally, the indenture governing the notes offered hereby, as well as the Credit Agreements, will permit us to incur additional secured indebtedness in the future, subject to certain restrictive covenants in the Credit Agreements. In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized, any secured indebtedness will be entitled to be paid from our assets securing such indebtedness before any payment may be made with respect to the notes offered hereby. Holders of the notes offered hereby will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same ranking as the notes (including the obligations under the Credit Agreements), and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets.

In addition, the notes will be structurally subordinated to all of the liabilities of our subsidiaries, which may include secured and unsecured indebtedness, trade payables, guarantees, lease obligations and letter of credit obligations of our subsidiaries. In the event of a dissolution, winding up, liquidation, reorganization or other bankruptcy proceeding of any of our subsidiaries, holders of their indebtedness and their creditors will generally be entitled to payment of their claims in full from the assets of those subsidiaries before any assets of the subsidiaries are made available for distribution to us.

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

While the indenture and the notes contain terms intended to provide some protections 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.

S-7

The term “Change of Control Triggering Event” (as defined in “Description of Notes — Certain Covenants — Purchase of Notes Upon a 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 the 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 governing 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 notes and the indenture governing 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.

Upon certain Change of Control Triggering Events, we may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the notes, which would violate the terms of the notes.

Upon the occurrence of specific kinds of Change of Control Triggering Events, holders of the notes of a series will have the right to require us to purchase all or any part of the notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. We may not have sufficient financial resources available to satisfy all of our obligations under the notes in the event of a Change of Control Triggering Event. Our failure to purchase the notes as required under the terms of the notes would result in an event of default under the terms of the notes and may trigger a cross-acceleration under the Credit Agreements, each of which could have material adverse consequences for us and the holders of the notes. See “Description of Notes—Certain Covenants —Purchase of Notes Upon a Change of Control Triggering Event.”

Our credit ratings are subject to change and may not reflect the risks of investing in the notes.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the notes. These credit ratings may not reflect the potential impact of risks relating to structure or marketing of the notes. Agency ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing agency. Each agency’s rating should be evaluated independently of any other agency’s rating.

Your ability to transfer the notes offered hereby will be limited by the absence of an active trading market.

There is currently no established trading market for the notes. We do not intend to apply for listing or quotation of the notes on any securities exchange. The underwriters have advised us that they intend to make a

S-8

market in the notes as permitted by applicable laws and regulations; however, the underwriters are not obligated to make a market in the notes, and they may discontinue their market-making activities at any time without notice. Therefore, an active market for the notes may not develop or, if developed, such a market may not continue. In addition, subsequent to their initial issuance, the notes may trade at a discount from their initial offering price based on, and the liquidity of any market for the notes will be impacted by, a number of factors, including prevailing interest rates, the market for similar notes, our performance and financial condition, the number of holders of the notes, the interest of securities dealers in making a market in the notes, general economic conditions and other factors. The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market price of the notes and the liquidity of any market for the notes.

S-9

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $                million, after deducting underwriting discounts and our estimated offering expenses. We intend to use the net proceeds from this offering (i) to repay a portion of the outstanding borrowings under our Credit Facility and (ii) for general corporate purposes.

The Credit Facility expires on June 28, 2022. As of June 30, 2020, borrowings of approximately $200 million were outstanding under the revolving portion of the Credit Facility at a weighted average interest rate of approximately 1.79% per annum.

Certain of the underwriters and/or their affiliates are lenders under the Credit Facility and will receive all or a portion of the net proceeds that we receive from this offering. These underwriters and/or their affiliates would have a “conflict of interest” pursuant to FINRA Rule 5121 if such underwriters and/or any of their affiliates receive at least 5% of the net offering proceeds. For more information, see “Underwriting (Conflicts of Interest)—Conflicts of Interest.”

DESCRIPTION OF NOTES

The notes will be senior unsecured debt securities issued under an indenture dated as of September 18, 2014 (the “base indenture”) between us and U.S. Bank National Association, as trustee (the “trustee”), as supplemented by a supplemental indenture to be dated as of                , 2020 (the “supplemental indenture” and, together with the base indenture, the “indenture”). In this description, the terms “we,” “our” and “us” each refer to Brown & Brown, Inc. and not its subsidiaries.

We have summarized material provisions of the indenture and the notes below. This summary is not complete and may not describe all of the provisions of the indenture or the notes that may be important to you. For additional information, you should carefully read each of the form of indenture and the form of note that is attached as an exhibit to the registration statement of which this prospectus supplement is a part.

General Terms of Notes

Interest and principal on the notes will be payable in U.S. dollars. The notes will be issued only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. There will be no sinking fund payments for the notes.

The security registrar and transfer agent for the notes will be the trustee until such time as a successor security registrar or transfer agent is appointed.

The notes will initially be limited to $                aggregate principal amount. However, the indenture does not limit the aggregate principal amount of the notes that we may issue under it. We may, without the consent of the noteholders, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the notes offered by this prospectus supplement (except for the issue date and public offering price); provided, however, such additional notes must be fungible with the notes offered by this prospectus supplement for U.S. federal income tax purposes. Any such additional notes will be a part of the series having the same terms as the notes and will be treated as a single class together with the notes for all purposes under the indenture, including waivers, amendments and redemptions. We may also issue other series of debt securities under the base indenture.

Interest and Maturity

The notes will bear interest at                % per year. Interest will be payable semi-annually in arrears on                 and                of each year (each, an “interest payment date”), beginning                , 2021.

Interest on the notes will accrue from and including                , 2020, or from and including the most recent date to which interest has been paid, as the case may be, to but excluding the interest payment date or the maturity date, as the case may be. Interest on the notes will be paid to noteholders of record on the applicable record date, which is the                or                immediately preceding the applicable interest payment date.

Interest on the notes will be computed on the basis of a 360 day year of twelve 30 day months. If an interest payment date for the notes falls on a day that is not a business day, the interest payment shall be postponed to the next succeeding business day, and no interest on such payment shall accrue for the period from and after such interest payment date. It will be an event of default under the indenture if we fail to pay interest when due and such failure continues for 30 days. See “—Events of Default.”

The notes will mature on                . If the maturity date for the notes falls on a day that is not a business day, the principal of and interest on the notes shall be due on the next succeeding business day, and no interest on such payment shall accrue for the period from and after the maturity date.

S-13

The term “business day” means any day that is not a Saturday, Sunday or other day on which commercial banks in New York City are authorized or required by law to remain closed.

Ranking

The notes will be our senior unsecured obligations, and will rank equally with all of our other senior unsecured indebtedness from time to time outstanding. As of June 30, 2020, we had $1,628.9 million of outstanding senior unsecured indebtedness for borrowed money, and our subsidiaries had no indebtedness for borrowed money outstanding. See “Risk Factors – The notes offered hereby will be unsecured and effectively subordinated to any future secured indebtedness and structurally subordinated to all of the liabilities of our subsidiaries.”

There are no provisions in the indenture or the notes that explicitly limit our ability to incur additional indebtedness. Accordingly, we could in the future enter into transactions that could substantially increase the amount of our indebtedness outstanding at that time.

Optional Redemption

The notes will be redeemable, in whole at any time or in part from time to time, at our option.

If the notes are redeemed prior to                , 20    (the date that is                months prior to the stated maturity date for the notes), the redemption price for the notes to be redeemed will equal the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to but excluding the redemption date:

If the notes are redeemed on or after                 , 20    (the date that is                months prior to the stated maturity date for the notes), the redemption price for the notes to be redeemed will equal 100% of the principal amount of such notes plus accrued and unpaid interest thereon to but excluding the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term (as measured from the redemption date) of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes.

“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker is provided with fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means J.P. Morgan Securities LLC and its successors and BofA Securities, Inc. and its successors, or one or more Reference Treasury Dealers as we may specify from time to time; provided, however, that if any of them ceases to be a primary U.S. Government securities dealer for the City of New York (each a “Primary Treasury Dealer”), we will substitute another Primary Treasury Dealer.

S-14

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate shall be calculated on the third business day preceding the redemption date, using the “business day” definition set forth above.

Notice of any redemption will be mailed at least 30 but not more than 60 days before the redemption date to each noteholder of record of the notes to be redeemed at its registered address. The notice of redemption for such notes will state, among other things, the amount of notes to be redeemed, the redemption date, the manner in which the redemption price will be calculated and the place or places where payment will be made upon presentation and surrender of the notes to be redeemed.

If less than all of the notes are to be redeemed at our option, the trustee will select, in a manner it deems fair and appropriate, the notes, or portions of the notes, to be redeemed.

Unless we default in the payment of the redemption price, interest will cease to accrue on any notes that have been called for redemption at the redemption date.

We shall not be required (i) to issue, register the transfer of or exchange any notes during the period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of notes selected for redemption and ending at the close of business on the day of such mailing or (ii) to register the transfer or exchange of any notes so selected for redemption in whole or in part, except the unredeemed portion of any such notes being redeemed in part.

In addition to our right to redeem the notes as set forth above, we may at any time and from time to time purchase notes in open market transactions, tender offers and otherwise.

Certain Covenants

Under the indenture, we agree to pay the interest, principal and any premium on the notes when due, and to maintain a place of payment. In addition, we must comply with the covenants described below.

Limitations on Liens on Stock of our Significant Subsidiaries

The indenture prohibits us and our subsidiaries from directly or indirectly creating, assuming, incurring or permitting to exist any Indebtedness (as defined below) secured by any lien on the voting stock or voting equity interest of any significant subsidiary (as such term is defined under Regulation S-X) (each a “Significant Subsidiary”) unless the notes then outstanding (and, if we so elect, any of our other Indebtedness that is not subordinate to the notes and with respect to which we are obligated to provide such security) are secured equally and ratably with such Indebtedness for so long as such Indebtedness is so secured.

“Indebtedness” is defined as the principal of and any premium and interest due on indebtedness of a person (as defined in the indenture), whether outstanding on the original date of issuance of the notes or thereafter created, incurred or assumed, which is (a) indebtedness for money borrowed, and (b) any amendments, renewals, extensions, modifications and refundings of any such indebtedness. For the purposes of this definition, “indebtedness for money borrowed” means (1) any obligation of, or any obligation guaranteed by, such person

S-15

for the repayment of borrowed money, whether or not evidenced by bonds, debentures, notes or other written instruments, (2) any obligation of, or any obligation guaranteed by, such person evidenced by bonds, debentures, notes or similar written instruments, including obligations assumed or incurred in connection with the acquisition of property, assets or businesses (provided, however, that the deferred purchase price of any business or property or assets shall not be considered Indebtedness if the purchase price thereof is payable in full within 90 days from the date on which such indebtedness was created), and (3) any obligations of such person as lessee under leases required to be capitalized on the balance sheet of the lessee under generally accepted accounting principles as in effect as of the date of the supplemental indenture and leases of property or assets made as part of any sale and lease-back transaction to which such person is a party. For purposes of this covenant only, Indebtedness also includes any obligation of, or any obligation guaranteed by, any person for the payment of amounts due under a swap agreement or similar instrument or agreement, or under a foreign currency hedge or similar instrument or agreement. If we are required to secure any outstanding notes equally and ratably with other Indebtedness under this covenant, we will be required to document our compliance with the covenant and thereafter the trustee will be authorized to enter into a supplemental agreement or indenture and to take such action as it may deem advisable to enable it to enforce the rights of the noteholders of the outstanding notes so secured.

Consolidation, Amalgamation, Merger and Sale of Assets

The indenture provides that we may consolidate with or merge or convert into, or convey, transfer or lease our properties or assets substantially as an entirety to, another person without the consent of any noteholders if, along with certain other conditions set forth in the indenture:

Thereafter, except in the case of a lease, the predecessor or transferor of such assets will be relieved of all obligations and covenants under the relevant indenture and the notes.

Purchase of Notes Upon a Change of Control Triggering Event

If a Change of Control Triggering Event occurs, unless we have exercised our right to redeem the Notes as described above under the heading “—Optional Redemption,” we will make an offer to each noteholder to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000 principal amount) of that noteholder’s notes at a repurchase price in cash equal to 101% of the aggregate principal amount of notes repurchased, plus any accrued and unpaid interest on the notes repurchased to the date of repurchase. Within 30 days following any Change of Control Triggering Event or, at our option, prior to any Change of Control, but after the public announcement of the pending Change of Control, we will mail a notice to each noteholder describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment date specified in the notice.

We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations 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 securities laws or regulations conflict with the Change of Control Triggering Event provisions of the notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Triggering Event provisions of the notes by virtue of such conflict.

On the Change of Control Triggering Event payment date, we will, to the extent lawful:

S-16

The paying agent will promptly pay, from funds deposited by us for such purpose, to each noteholder properly tendered, the purchase price for the notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each noteholder a new note equal in principal amount to any unpurchased portion of any notes surrendered.

We will not be required to make an offer to repurchase the notes upon a Change of Control Triggering Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all notes properly tendered and not withdrawn under its offer.

Set forth below are certain of the defined terms used herein.

“Change of Control” means the occurrence of any of the following:

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Ratings Decline.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) (or, in each case, if such Rating Agency ceases to rate the notes for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Moody’s” means Moody’s Investors Service Inc. and any successor to its rating agency business.

“Person” means any individual, corporation, partnership, joint venture, association, joint-stock company, trust, unincorporated organization, limited liability company or government or other entity.

“Rating Agency” means:

S-17

“Ratings Decline” means at any time during the period commencing on the earlier of, (i) the occurrence of a Change of Control or (ii) public notice of the occurrence of a Change of Control or the intention by the Company to effect a Change of Control, and ending 60 days thereafter (which period shall be extended so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) that (a) the rating of the notes shall be reduced by both Rating Agencies and (b) the notes shall be rated below Investment Grade by each of the Rating Agencies.

“S&P” means S&P Global Ratings and any successor to its rating agency business.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person the holders of which are at the time entitled to vote generally in the election of the board of directors or similar governing body of such Person.

Provision of Compliance Certificate

We are required under the indenture to deliver to the trustee within 120 days after the end of each fiscal year an officer’s certificate certifying as to our compliance with all conditions and covenants under the relevant indenture, or if we are not in compliance, identifying and describing the nature and status of such non-compliance.

Events of Default

The following events will constitute an event of default under the indenture with respect to the notes (whatever the reason for such event of default and whether it will be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

If an event of default with respect to the notes (other than an event of default resulting from certain events of bankruptcy or insolvency) occurs and is continuing, the trustee or the noteholders of at least 25% in aggregate principal amount of the outstanding notes may declare the principal of all notes, plus accrued and unpaid interest to the date of acceleration, immediately due and payable. Upon an event of default resulting from certain events of bankruptcy or insolvency, the principal of all notes, plus accrued and unpaid interest to the date of acceleration, shall be immediately due and payable.

The noteholders of a majority in principal amount of the outstanding notes may waive any default or event of default with respect to such notes and its consequences under the indenture except a continuing default or event of default in the payment of interest or any premium on, or the principal of, the notes.

S-18

If an event of default occurs and is continuing, the trustee will be under no obligation to exercise any of its rights or powers under the indenture unless the noteholders have offered the trustee reasonable indemnity satisfactory to the trustee against the costs, expenses and liabilities that it might incur. The noteholders of a majority in principal amount of the outstanding notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the notes, provided that:

Modification of Indenture; Waiver

Without the consent of any noteholders, we and the trustee may modify or amend the indenture with respect to the notes to:

We and the trustee may modify or amend the indenture with the written consent of the noteholders of a majority of the aggregate principal amount of the outstanding notes then outstanding under the indenture; provided, however, that no such modification or amendment may, without the consent of each noteholder affected by the change:

S-19

No Personal Liability of Directors, Officers, Employees and Shareholders

None of our directors, officers, employees, incorporators or shareholders, as such, will have any liability for any of our obligations under the notes or the indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each noteholder by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Discharge, Defeasance and Covenant Defeasance

Defeasance and Discharge

We may discharge any and all obligations in respect of the notes (except for certain obligations to register the transfer or exchange of notes, to replace stolen, destroyed, lost or mutilated notes, to maintain paying agencies, to execute and furnish definitive securities evidenced by temporary securities, to return moneys deposited with or paid to the trustee or any paying agent remaining unclaimed for three years, to compensate and indemnify the trustee or to furnish such trustee (if that trustee is not the registrar) with the names and addresses of noteholders). This discharge, referred to as defeasance, will occur only if, among other things:

In addition, we may also obtain a discharge of the indenture with respect to all debt securities issued under the indenture by depositing with the trustee, in trust, enough money to pay all amounts due on the debt securities on the date those payments are due or upon redemption of all of those debt securities, so long as those debt securities are by their terms to become due and payable within one year or are to be called for redemption within one year.

Defeasance of Certain Covenants and Certain Events of Default

Upon compliance with certain conditions:

S-20

The conditions include, among other things:

Covenant Defeasance and Certain Other Events of Default

If we exercise the option to effect a covenant defeasance with respect to the notes as described above and the notes are thereafter declared due and payable because of an event of default (other than an event of default caused by failing to comply with the covenants that are defeased), the amount of money and securities we have deposited with the trustee would be sufficient to pay amounts due on the notes on their respective due dates but may not be sufficient to pay amounts due on the notes at the time of acceleration resulting from that event of default. However, we would remain liable for any shortfall.

Global Clearance and Settlement Procedures

We will issue the notes in the form of one or more fully registered global notes (the “Global Notes”). Investors in the Global Notes may hold a beneficial interest in such Global Notes through The Depository Trust Company (“DTC”), Clearstream Banking, S.A. (“Clearstream”) or the Euroclear System (“Euroclear”) or through participants. The notes may be traded as home market instruments in both the European and U.S. domestic markets. Initial settlement and all secondary trades will settle as set forth below.

Clearstream has advised that it is incorporated under the laws of the Grand Duchy of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”). Clearstream facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (CSSF). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

S-21

Distributions, to the extent received by the U.S. Depositary (as defined below) for Clearstream, with respect to the notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear has advised that it was created in 1968 to hold securities for its participants (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, eliminating the need for physical movement of certificates and eliminating any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/ NV (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator has advised us that it is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding through Euroclear Participants.

Distributions, to the extent received by the U.S. Depositary for Euroclear, with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions.

Individual certificates in respect of notes will not be issued in exchange for the Global Notes, except in very limited circumstances, including those instances that follow: if DTC notifies us that it is unwilling or unable to continue as a clearing system in connection with a Global Note or DTC ceases to be a clearing agency registered under the Exchange Act, and in each case we do not appoint a successor clearing system within 90 days after receiving such notice from Euroclear, Clearstream or DTC or on becoming aware that DTC is no longer so registered, we will issue or cause to be issued individual certificates in registered form on registration of transfer of or in exchange for book-entry interests in the notes represented by such Global Note upon delivery of such Global Note for cancellation.

Title to book-entry interests in the notes will pass by book-entry registration of the transfer within the records of Euroclear, Clearstream or DTC, as the case may be, in accordance with their respective procedures. Book-entry interests in the notes may be transferred within Euroclear and within Clearstream and between Euroclear and Clearstream in accordance with procedures established for these purposes by Euroclear and Clearstream. Book-entry interests in the notes may be transferred within DTC in accordance with procedures established for this purpose by DTC. Transfers of book-entry interests in the notes between Euroclear and Clearstream and DTC may be effected in accordance with procedures established for this purpose by Euroclear, Clearstream and DTC.

S-22

Initial Settlement

All Global Notes will be registered in the name of Cede & Co. as nominee of DTC. Investors’ interests in the Global Notes will be represented through financial institutions acting on their behalf as direct and indirect participants in DTC. As a result, Clearstream and Euroclear will hold positions on behalf of their participants through their respective U.S. depositaries (each, a “U.S. Depositary”), which in turn will hold such positions in accounts as participants of DTC.

Notes held through DTC will be settled in immediately available funds. Investor securities custody accounts will be credited with their holdings against payment on the settlement date. Notes held through Clearstream or Euroclear accounts will follow the settlement procedures applicable to conventional eurobonds, except that there will be no temporary global security and no “lock-up” or restricted period. Notes will be credited to the securities custody accounts on the settlement date against payment.

Secondary Market Trading

Since the purchaser determines the place of delivery, it is important to establish at the time of the trade where both the purchaser’s and seller’s accounts are located to ensure that settlement can be made on the desired value date.

Trading between DTC Participants. Secondary market trading between DTC participants will be settled in immediately available funds.

Trading between Clearstream and/or Euroclear Participants. Secondary market trading between Clearstream participants and/or Euroclear participants will be settled using the procedures applicable to conventional eurobonds.

Trading between DTC Seller and Clearstream or Euroclear Purchaser. When beneficial interests in the Global Notes are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser will send instructions to Clearstream or Euroclear through a participant at least one business day prior to settlement. Clearstream or Euroclear will instruct the U.S. Depositary, as the case may be, to receive a beneficial interest in the Global Notes against payment. Unless otherwise set forth in this prospectus supplement, payment will include interest accrued on the beneficial interest in the Global Notes so transferred from and including the last interest payment date to and excluding the settlement date, on the basis on which interest is calculated on the notes. For transactions settling on the 31st of the month, payment will include interest accrued to and excluding the first day of the following month. Payment will then be made by the U.S. Depositary to the DTC participant’s account against delivery of the beneficial interest in the Global Notes. After settlement has been completed, the beneficial interest in the Global Notes will be credited to the respective clearing system and by the clearing system, in accordance with its usual procedures, to the Clearstream or Euroclear participant’s account. The securities credit will appear the next day (European time) and the cash debit will be back-valued to, and interest on the beneficial interest in the Global Notes will accrue from, the value date (which would be the preceding day when settlement occurred in New York). If settlement is not completed on the intended value date (that is, the trade fails), the Clearstream or Euroclear cash debit will be valued instead as of the actual settlement date.

Clearstream participants and Euroclear participants will need to make available to the respective clearing systems the funds necessary to process same-day funds settlement. The most direct means of doing so is to preposition funds for settlement, either from cash on hand or existing lines of credit, as they would for any settlement occurring within Clearstream or Euroclear. Under this approach, they may take on credit exposure to Clearstream or Euroclear until the beneficial interests in the Global Notes are credited to their accounts one day later.

As an alternative, if Clearstream or Euroclear has extended a line of credit to them, participants can elect not to preposition funds and allow that credit line to be drawn upon to finance settlement. Under this procedure,

S-23

Clearstream participants or Euroclear participants purchasing a beneficial interest in the Global Notes would incur overdraft charges for one day, assuming they cleared the overdraft when the beneficial interests in the Global Notes were credited to their accounts. However, interest on the beneficial interests in the Global Notes would accrue from the value date. Therefore, in many cases the investment income on the Global Notes earned during that one-day period may substantially reduce or offset the amount of such overdraft charges, although this result will depend on each participant’s particular cost of funds.

Since the settlement is taking place during New York business hours, DTC participants can employ their usual procedures for sending a beneficial interest in the Global Notes to the U.S. Depositary for the benefit of Clearstream participants or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. Thus, to the DTC participant a cross-market transaction will settle no differently than a trade between two DTC participants.

Trading between Clearstream or Euroclear Seller and DTC Purchaser. Due to time zone differences in their favor, Clearstream and Euroclear participants may employ their customary procedures in transactions in which a beneficial interest in the Global Notes is to be transferred by the respective clearing system, through the U.S. Depositary, to a DTC participant. The seller will send instructions to Clearstream or Euroclear through a participant at least one business day prior to settlement. In these cases, Clearstream or Euroclear will instruct the U.S. Depositary, as appropriate, to deliver the beneficial interest in the Global Notes to the DTC participant’s account against payment. Payment will include interest accrued on the beneficial interest in the Global Notes from and including the last coupon payment date to and excluding the settlement date on the basis on which interest is calculated on the Global Notes. For transactions settling on the 31st of the month, payment will include interest accrued to and excluding the first day of the following month. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, and receipt of the cash proceeds in the Clearstream or Euroclear participant’s account would be back-valued to the value date (which would be the preceding day, when settlement occurred in New York). Should the Clearstream or Euroclear participant have a line of credit with its respective clearing system and elect to be in debit in anticipation of receipt of the sale proceeds in its account, the back-valuation will extinguish any overdraft charges incurred over that one-day period. If settlement is not completed on the intended value date (that is, the trade fails), receipt of the cash proceeds in the Clearstream or Euroclear participant’s account would instead be valued as of the actual settlement date.

Finally, day traders that use Clearstream or Euroclear and that purchase beneficial interests in the Global Notes from DTC participants for credit to Clearstream participants or Euroclear participants should note that these trades would automatically fail on the sale side unless affirmative action is taken. At least three techniques should be readily available to eliminate this potential problem:

Although DTC, Clearstream, and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of beneficial interests in the Global Notes among participants of DTC, Clearstream, and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

S-24

Applicable Law

The notes and the indenture will be governed by and construed in accordance with the laws of the State of New York.

Additional Terms

For additional important information about the notes, see “Description of Debt Securities” in the accompanying prospectus. That information includes:

To the extent any information about the notes varies between this prospectus supplement and the accompanying prospectus, you should rely on the information contained in this prospectus supplement.

S-25

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

This section describes the material United States federal income tax and certain estate tax consequences of owning the notes we are offering. It applies to you only if you acquire notes in the offering at a price equal to the issue price of the notes (generally the first price at which a substantial amount of the notes is sold for cash other than to bond houses, brokers or similar persons or organizations acting in the capacity of initial purchasers, placement agents or wholesalers) and you hold your notes as capital assets for tax purposes. This section does not apply to you if you are a member of a class of holders subject to special rules, such as, but not limited to:

If you purchase notes at a price other than the issue price, the amortizable bond premium or market discount rules may also apply to you. You should consult your tax advisor regarding this possibility.

This section is based on the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations under the Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis, or may be subject to different interpretations.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the notes, the United States federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership holding the notes should consult its tax advisor with regard to the United States federal income tax treatment of an investment in the notes.

Please consult your own tax advisor concerning the consequences of owning these notes in your particular circumstances under the Code and the laws of any other taxing jurisdiction.

Additional Payments. In certain circumstances, we may be obligated to pay amounts in excess of stated interest or principal on the notes. We have no present intention to engage in a transaction involving a Change of Control, and therefore, we believe that the likelihood that we will be obligated to make any such payments as a result of a contingency described under “Description of Notes—Purchase of Notes Upon a Change of Control Triggering Event” is remote. Accordingly, we do not intend to treat the potential payment of these amounts as subjecting the notes to the provisions of the United States Treasury regulations relating to “contingent payment debt instruments.” Our determination is binding on you, unless you disclose a contrary position in a statement attached to your timely filed United States federal income tax return for the taxable year during which the notes were acquired. Our determination is not, however, binding on the Internal Revenue Service (“IRS”), and if the IRS were to challenge this determination, the tax consequences to you could differ from those discussed herein.

S-26

For example, if the notes are treated as contingent payment debt instruments, any gain on sale or other disposition of the notes would be treated as ordinary income rather than capital gain. The remainder of this disclosure assumes that the notes will not be treated as contingent payment debt instruments for United States federal income tax purposes.

Original Issue Discount. The following discussion assumes that the notes will not be issued with more than a de minimis amount of original issue discount (“OID”). If the issue price of a note is less than its stated redemption price at maturity (generally, its principal amount) by more than a de minimis amount, you will be subject to special United States federal income tax rules with respect to this OID. OID will be considered de minimis if it is less than 0.25% of the stated redemption price at maturity multiplied by the number of complete years to maturity from the issue date of the notes. If the notes are issued with more than a de minimis amount of OID, unless an exception applies, you will be required to include such OID in income for United States federal income tax purposes as it accrues in accordance with a constant yield method based on a compounding of interest, even though the cash attributable to this income will not be received until a note is sold, exchanged, redeemed or otherwise disposed.

United States Holders

This subsection describes the tax consequences to a United States Holder. You are a “United States Holder” if you are a beneficial owner of a note and you are:

If you are not a United States Holder, this subsection does not apply to you and you should refer to “United States Alien Holders” below.

Payments of Interest. You will be taxed on interest on your note as ordinary income at the time you receive the interest or when it accrues, depending on your method of accounting for tax purposes.

Sale, Retirement or Other Taxable Disposition of a Note. You will generally recognize capital gain or loss on the sale, retirement or other taxable disposition of your note equal to the difference between the amount you realize on the sale or retirement, excluding any amounts attributable to accrued but unpaid interest (which will be treated as interest payments as described above under “—Payments of Interest”), and your tax basis in your note. Your tax basis in your note generally will be the amount you paid for the note. Capital gain of certain non-corporate United States Holders (including individuals) is generally taxed at preferential rates where the property is held for more than one year. The deductibility of capital losses is subject to limitations.

Medicare Tax. A United States Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax (the “Medicare tax”) on the lesser of (1) the United States Holder’s “net investment income” (or “undistributed net investment income” in the case of an estate or trust) for the relevant taxable year and (2) the excess of the United States Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals is between $125,000 and $250,000, depending on the individual’s circumstances). A holder’s net investment income generally

S-27

includes its interest income and its net gains from the disposition of notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a United States Holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the notes.

United States Alien Holders

This subsection describes the tax consequences to a United States Alien Holder. You are a “United States Alien Holder” if you are the beneficial owner of a note and you are not classified as a partnership for U.S. federal income tax purposes and you are not a United States Holder.

If you are a United States Holder, this subsection does not apply to you.

Under United States federal income and estate tax law, and subject to the discussions of FATCA withholding and backup withholding below, if you are a United States Alien Holder of a note:

Payments of Interest. We and other United States payors generally would not be required to deduct United States withholding tax from payments of interest to you if:

S-28

If you cannot satisfy the requirements described above, payments of interest will be subject to United States federal withholding at a rate of 30% unless you provide the applicable withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other acceptable substitute form) claiming an exemption from or reduction in withholding under the benefit of an applicable income tax treaty or the interest is effectively connected with the conduct of a trade or business in the United States and you satisfy the certification requirements described below under “—Income or Gain Effectively Connected with a United States Trade or Business.”

Sale or Retirement of a Note. Except with respect to accrued but unpaid interest, which will be subject to the rules described above under “—Payments of Interest,” no deduction for any United States federal withholding tax would be made from any gain that you realize on the sale or retirement or other disposition of your note, unless (i) such gain is effectively connected with your conduct of a trade or business in the United States and, if an income tax treaty applies, is attributable to a permanent establishment maintained by you in the United States, in which case, you will be subject to United States federal income tax in the manner described below under “—Income or Gain Effectively Connected with a United States Trade or Business” or (ii) you are an individual who is present in the United States for 183 days or more in the taxable year of disposition, and certain other conditions are met, in which case, you will be subject to a 30% (or lower applicable income tax treaty rate) United States federal income tax on the gain derived from the sale or retirement, which may be offset by certain United States source capital losses.

Income or Gain Effectively Connected with a United States Trade or Business. If you are engaged in a trade or business in the United States, and if interest on your note, or gain realized on the sale or retirement of your note is effectively connected with the conduct of such trade or business, you generally will be subject to regular United States federal income tax on such income or gain in the same manner as if you were a United States Holder. If you are eligible for the benefits of an income tax treaty between the United States and your country of residence, any “effectively connected” income or gain generally will be subject to United States federal income tax only if it is also attributable to a permanent establishment maintained by you in the United States. Payments of interest that are effectively connected with a United States trade or business (and, if an income tax treaty applies, attributable to a permanent establishment), and therefore included in your gross income, will not be subject to the 30% withholding, provided that you claim exemption from withholding by providing the United States payor with a properly completed IRS Form W-8ECI. In addition, if you are a foreign corporation, you may also be subject to a branch profits tax equal to 30% (or such lower rate provided by an applicable income tax treaty) of your effectively connected earnings and profits for the taxable year, subject to certain adjustments.

Estate Tax. Further, a note held by an individual who at death is not a citizen or resident of the United States would not be includible in the individual’s gross estate for United States federal estate tax purposes if:

S-29

FATCA Withholding

Pursuant to Sections 1471 through 1474 of the Code, commonly known as the Foreign Account Tax Compliance Act (“FATCA”), a 30% withholding tax (“FATCA withholding”) may be imposed on payments of interest to you or to certain foreign financial institutions, investment funds and other non-United States persons receiving payments of interest on your behalf if you or such persons fail to comply with certain information reporting requirements. Payments of interest that you receive in respect of the notes could be affected by this withholding if you are subject to the FATCA information reporting requirements and fail to comply with them or if you hold notes through a non-United States person (e.g., a foreign bank or broker) that fails to comply with these requirements (even if payments to you would not otherwise have been subject to FATCA withholding). Payments of gross proceeds from the sale or other disposition of notes were scheduled to become subject to FATCA withholding for dispositions occurring on or after January 1, 2019. However, proposed regulations, which taxpayers are entitled to rely on, eliminate the requirement for FATCA withholding with respect to such gross proceeds. You should consult your own tax advisors regarding the relevant United States law and other official guidance on FATCA withholding.

We will not pay any additional amounts in respect of FATCA withholding, so if this withholding applies, you will receive significantly less than the amount that you would have otherwise received with respect to your notes. Depending on your circumstances, you may be entitled to a refund or credit in respect of some or all of this withholding. However, even if you are entitled to have any such withholding refunded, the required procedures could be cumbersome and significantly delay your receipt of any amounts withheld.

Backup Withholding and Information Reporting

If you are a non-corporate United States Holder, information reporting requirements, on IRS Form 1099, generally would apply to payments of principal and interest on a note within the United States, and the payment of proceeds to you from the sale of a note effected at a United States office of a broker.

Additionally, backup withholding may apply to such payments if you fail to comply with applicable certification requirements or are notified by the IRS that you have failed to report all interest and dividends required to be shown on your federal income tax returns.

If you are a United States Alien Holder, you are generally exempt from backup withholding and information reporting requirements with respect to payments of principal and interest made to you outside the United States by the United States payor. You are also generally exempt from backup withholding and information reporting requirements in respect of payments of principal and interest made within the United States and the payment of the proceeds from the sale of a note effected at a United States office of a broker, as long as either: (i) the payor or broker does not have actual knowledge or reason to know that you are a United States person and you have furnished a valid IRS Form W-8 or other documentation upon which the payor or broker may rely to treat the payments as made to a non-United States person, or (ii) you otherwise establish an exemption.

Payment of the proceeds from the sale of a note effected at a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, a sale effected at a foreign office of a broker could be subject to information reporting in the same manner as a sale within the United States (and in certain cases may be subject to backup withholding as well) if: (i) the broker has certain connections to the United States, (ii) the proceeds or confirmation are sent to the United States or (iii) the sale has certain other specified connections with the United States.

You generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed your income tax liability by timely filing a refund claim with the IRS.

UNDERWRITING (CONFLICTS OF INTEREST)

J.P. Morgan Securities LLC, BofA Securities, Inc., PNC Capital Markets LLC and Truist Securities, Inc. are acting as joint book-running managers of the offering and are acting as representatives of the several underwriters named below.

Subject to the terms and conditions contained 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 amount of notes set forth opposite such underwriter’s name.

The underwriting agreement is subject to a number of terms and conditions and provides that the obligations of the underwriters to pay for and accept delivery of the notes offered hereby are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes offered hereby if they purchase any of the notes.

The underwriters have advised us that they propose initially to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer the notes to certain dealers at the public offering price less a concession not to exceed             % of the principal amount of the notes. The underwriters may allow, and dealers may reallow, a concession not to exceed             % of the principal amount of the notes on sales to other dealers. After the initial offering of the notes to the public, the representatives may change the public offering price and concessions. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

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

We have agreed to indemnify the several 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.

The notes are a new issue of securities with no established trading market. We do not intend to list the notes on any securities exchange. If a trading market does not develop or is not maintained, holders of the notes may find it difficult or impossible to resell their notes. If a trading market were to develop, the notes may trade at prices that are higher or lower than their initial offering price, depending on many factors, including prevailing interest rates, our operating results and financial condition, and the market for similar securities. We have been advised by the underwriters that they intend to make a market in the notes. However, the underwriters are not obligated to do so and may discontinue any market making at any time without notice. Accordingly, there can be no assurance regarding any future development of a trading market for the notes or the ability of holders of the notes to sell their notes at all or the price at which such holders may be able to sell their notes. In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include overallotment, syndicate covering transactions and stabilizing transactions.

Overallotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions

S-31

involve purchases of notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the underwriters, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities with respect to the notes 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 otherwise would 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.

The Company expects that the delivery of the notes will be made against payment therefor on the closing date specified on the cover page of this prospectus supplement, which will be the fifth business day following the date of this prospectus supplement. Under rules of the SEC, trades in the secondary market generally are required to settle in two business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes before the second business day prior to the closing date specified on the cover page of this prospectus supplement will be required, by virtue of the fact that the normal settlement date for that trade would occur prior to the closing date for the issuance of the notes, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement, and should consult their own advisors with respect to these matters.

Conflicts of Interest

Affiliates of J.P. Morgan Securities LLC, BofA Securities, Inc., Truist Securities, Inc., BMO Capital Markets Corp., U.S. Bancorp Investments, Inc. and Wells Fargo Securities, LLC are lenders under the Credit Facility. Such affiliates will receive a pro rata portion of the proceeds from this offering used to reduce amounts outstanding under the Credit Facility. If such underwriters and/or their affiliates receive at least 5% of the net offering proceeds the underwriter and/or their affiliates would have a “conflict of interest” pursuant to FINRA Rule 5121. Accordingly, this offering would be made in compliance with FINRA Rule 5121 and any underwriter that has a conflict of interest pursuant to the rule would not confirm sales to accounts in which it exercises discretionary authority without the prior written consent of the customer. However, because the notes are investment grade rated, no “qualified independent underwriter” is required to be appointed in connection with this offering.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to the Company and to persons and entities with relationships with the Company, for which they received or will receive customary fees and expenses. U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee under the indenture governing the notes.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the Company (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the Company. If any of the underwriters or their

S-32

affiliates has a lending relationship with the Company, certain of those underwriters or their affiliates routinely hedge, and certain of those underwriters or their affiliates may hedge, their credit exposure to the Company consistent with their customary risk management policies. Typically, such 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 the Company’s securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (“NI 33-105”), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

We make “forward-looking statements” within the “safe harbor” provision of the Private Securities Litigation Reform Act of 1995, as amended, throughout this prospectus and in the documents we incorporate by reference into this prospectus, including those relating to the potential effects of the COVID-19 pandemic (“COVID-19”) on the Company’s business, operations, financial performance and prospects. You can identify these statements by forward-looking words such as “may,” “will,” “should,” “expect,” “anticipate,” “believe,” “intend,” “estimate,” “plan” and “continue” or similar words. We have based these statements on our current expectations about potential future events. Although we believe the expectations expressed in the forward-looking statements included in this prospectus and the reports, statements, information and announcements incorporated by reference into this prospectus are based upon reasonable assumptions within the bounds of our knowledge of our business, a number of factors could cause actual results to differ materially from those expressed in any forward-looking statements, whether oral or written, made by us or on our behalf. Further, statements about the effects of COVID-19 on our business, operations, financial performance and prospects may constitute forward-looking statements and are subject to the risk that the actual impacts may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including the scope and duration of COVID-19, actions taken by governmental authorities in response to COVID-19, and the direct and indirect impact of COVID-19 on our customers, insurance carriers, third parties and us. Many of these factors have previously been identified in filings or statements made by us or on our behalf. Important factors which could cause our actual results to differ materially from the forward-looking statements in this prospectus include, but are not limited to, the following items:

For a further list and description of various risks, relevant factors and uncertainties that could cause future results or events to differ materially from those expressed or implied in our forward-looking statements, see the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections contained in any applicable prospectus supplement and the documents incorporated by reference in this prospectus and any prospectus supplement.

Assumptions as to any of the foregoing and all statements are not based upon historical fact, but rather reflect our current expectations concerning future results and events. Forward-looking statements that we make or that are made by others on our behalf are based upon a knowledge of our business and the environment in which we operate, but because of the factors listed above, among others, actual results may differ from those in the forward-looking statements. Consequently, these cautionary statements qualify all of the forward-looking statements we make herein. We cannot assure you that the results or developments anticipated by us will be realized or, even if substantially realized, that those results or developments will result in the expected consequences for us or affect us, our business or our operations in the way we expect. We caution readers not to place undue reliance on these forward-looking statements, which speak only as of their dates. We assume no obligation to update any of the forward-looking statements.

BROWN & BROWN, INC.

Our Business

We are a diversified insurance agency, wholesale brokerage, insurance programs and service organization headquartered in Daytona Beach, Florida that markets and sells insurance products and services to our customers. As an insurance intermediary, our principal sources of revenue are commissions paid by insurance companies and, to a lesser extent, fees paid directly by customers. Commission revenues generally represent a percentage of the premium paid by an insured and are affected by fluctuations in both premium rate levels charged by insurance companies and the insureds’ underlying “insurable exposure units,” which are units that insurance companies use to measure or express insurance exposed to risk (such as property values, or sales and payroll levels) to determine what premium to charge the insured. Insurance companies establish these premium rates based upon many factors, including loss experience, risk profile and reinsurance rates paid by such insurance companies, none of which we control.

The volume of business from new and existing customers, fluctuations in insurable exposure units, changes in premium rate levels, changes in general economic and competitive conditions, a health pandemic and the occurrence of catastrophic weather events all affect our revenues. For example, level rates of inflation or a general decline in economic activity could limit increases in the values of insurable exposure units. Conversely, increasing costs of litigation settlements and awards could cause some customers to seek higher levels of insurance coverage. Historically, our revenues have typically grown as a result of our focus on net new business growth and acquisitions. We foster a strong, decentralized sales and service culture with the goal of consistent, sustained growth over the long-term.

Our business is divided into four reportable segments:

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of any securities offered by this prospectus will be used for general corporate purposes. General corporate purposes may include, without limitation:

Our management will retain broad discretion in the allocation of the net proceeds from the sale of these securities. Pending any specific application described in the applicable prospectus supplement, net proceeds may be initially invested in short-term interest-bearing accounts, securities or similar investments or applied to reduce short-term indebtedness.

DESCRIPTION OF DEBT SECURITIES

The following description sets forth general terms and provisions of the debt securities that we may offer under this prospectus and the applicable prospectus supplement. We will provide additional or different terms of the debt securities in the applicable prospectus supplement.

Any debt securities that we issue will be issued under an indenture, dated as of September 18, 2014, between us and U.S. Bank National Association, as trustee. The indenture is incorporated by reference to the registration statement of which this prospectus forms a part. The following description of the terms of the debt securities sets forth certain general terms and provisions. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities will be described in the related prospectus supplement.

This prospectus summarizes what we believe to be the material provisions of the indenture and the debt securities that we may issue under such indenture. This summary is not complete and may not describe all of the provisions of the indenture or of the debt securities that may be important to you. For additional information, you should carefully read the indenture that is incorporated by reference to the registration statement of which this prospectus forms a part.

In addition, when we offer to sell a particular series of debt securities, we will describe the specific terms of those debt securities and the indenture in a supplement to this prospectus. The terms of such a particular series of debt securities may differ from the terms described in this prospectus. As a result, the particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to the debt securities, will be described in the applicable prospectus supplement.

Accordingly, for a description of the terms of a particular issue of debt securities, reference must be made to both the applicable prospectus supplement and to the following description.

General

The debt securities may be issued in one or more series as may be authorized from time to time. Reference is made to the applicable prospectus supplement for the following terms of the debt securities (if applicable):

5

One or more series of debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. One or more series of debt securities may be variable-rate debt securities that may be exchanged for fixed-rate debt securities.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in the applicable prospectus supplement.

Debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional United States federal income tax considerations will be set forth in the applicable prospectus supplement.

6

The term “debt securities” includes debt securities denominated in U.S. dollars or, if specified in the applicable prospectus supplement, in any other freely transferable currency or units based on or relating to foreign currencies.

We expect most debt securities to be issued in fully registered form without coupons and in denominations of $1,000 and any integral multiples thereof. Subject to the limitations provided in the indenture and in the prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the corporate office of the trustee or the principal corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the prospectus supplement. Global securities will be issued in registered form and in either temporary or definitive form. Unless and until it is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to any debt securities of a series and the rights of and limitations upon owners of beneficial interests in a global security will be described in the applicable prospectus supplement.

Governing Law

Unless otherwise specified in any prospectus supplement, the indenture and the debt securities shall be governed by, and construed in accordance with, the laws of the State of New York.

DESCRIPTION OF CAPITAL STOCK

The following descriptions of our capital stock and provisions of our Amended and Restated Articles of Incorporation, as amended (our “Articles of Incorporation”), and our By-Laws, as amended and restated (our “By-Laws”), are summaries of their material terms and provisions and are not complete and are subject to, and qualified in their entirety by reference to, each of the items identified below. For a complete description of our capital stock, Articles of Incorporation and By-Laws, please refer to our Articles of Incorporation, By-Laws and the applicable provisions of the Florida Business Corporations Act (the “FBCA”).

Authorized Capital Stock

Under our Articles of Incorporation, the number of shares of capital stock that we have authority to issue is 560,000,000, par value $.10 per share.

Common Stock

Voting. Each holder of our common stock is entitled to one vote for each share held. Shareholders do not have the right to cumulate their votes in elections of directors. Accordingly, directors are elected by a majority of the votes present in person or represented by proxy at the meeting and actually cast by the shares entitled to vote in uncontested elections. If our Board of Directors (the “Board”) determines that an election is contested, then directors are elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors.

Dividends. Holders of our common stock will be entitled to dividends on a pro rata basis upon declaration of dividends by our Board. Dividends will be payable only out of unreserved and unrestricted surplus that is legally available for the payment of dividends. Dividends that may be declared on our common stock will be paid in an equal amount to the holder of each share. Any determination to declare or pay dividends in the future will be at the discretion of our Board and will depend on our results of operations, financial condition, contractual or legal restrictions and other factors deemed relevant by our Board.

7

Our common stock is listed on the New York Stock Exchange under the symbol “BRO.”

No Redemption, Conversion or Preemptive Rights

No preemptive rights are conferred upon the holders of such stock and there are no liquidation or conversion rights. There are no redemption or sinking fund provisions and there is no liability to further calls or to assessments by us.

Fully Paid and Nonassessable

When we issue shares of our common stock, the shares will be fully paid and nonassessable, which means that the full purchase price of the shares will have been paid and holders of the shares will not be assessed any additional monies for the shares.

No Restrictions on Transfer

Neither our Articles of Incorporation nor our By-Laws contain any restrictions on the transfer of our common stock. In the case of any transfer of our common stock, there may be restrictions imposed by applicable securities laws.

Transfer Agent and Registrar

The Transfer Agent and Registrar for our common stock is American Stock Transfer & Trust Company.

Certain Anti-Takeover Provisions of Our Articles of Incorporation, By-Laws and the FBCA

FBCA

We are subject to certain anti-takeover provisions that apply to public corporations under Florida law. Pursuant to Section 607.0901 of the FBCA, a publicly-held Florida corporation may not engage in a broad range of business combinations or other extraordinary corporate transactions with an “interested shareholder” without the authorization of the holders of two-thirds of the voting shares of such corporation (excluding shares held by the interested shareholder) at an annual or special meeting of shareholders, unless:

An “interested shareholder” is defined as a person who beneficially owns more than 15% of a corporation’s outstanding voting shares. We have not made an election in our Articles of Incorporation to opt out of Section 607.0901.

8

In addition, we are subject to Section 607.0902 of the FBCA which prohibits the voting of shares in a publicly-held Florida corporation that are acquired in a “control share acquisition” unless: (1) our Board approved such acquisition prior to its consummation; or (2) after such acquisition, in lieu of prior approval by our Board, the holders of a majority of the corporation’s voting shares, exclusive of shares owned by officers of the corporation, employee directors or the acquiring party, approve the granting of voting rights as to the shares acquired in the control share acquisition. A “control share acquisition” is defined as an acquisition that immediately thereafter entitles the acquiring party to exercise or direct the exercise of the voting power of the corporation in an election of directors within any of the following ranges:

These statutory provisions may prevent takeover attempts that might result in a premium over the market price for shares of our common stock.

Articles of Incorporation and By-Laws

Number of Directors; Removal; Filling of Vacancies

Our Articles of Incorporation and By-Laws provide that our Board shall consist of nine directors, which number may be increased or diminished from time to time by resolution of the Board, but shall never be less than three directors.

Our shareholders may remove from office any director and elect his or her successor at any meeting called for that purpose by vote of a majority of the common stock issued and outstanding. When the office of a director becomes vacant for any reason, the remaining directors may elect a successor by a majority vote.

Shareholder Action

Our By-Laws provide that shareholder action may be taken at an annual or special meeting of shareholders. Special meetings of shareholders may be called only by our President or our Board, whenever he, she or they deem it proper and shall be called by the President or by our Board upon the written request of the shareholders holding a majority of common stock outstanding, subject to certain additional requirements set forth in our By-Laws.

Advance Notice for Shareholder Proposals or Nominations at Meetings

Our By-Laws establish an advance notice procedure for shareholder proposals to be brought before any meeting of shareholders and for nominations by shareholders of candidates for election as directors at meetings at which directors are to be elected.

In addition, for business to be properly brought before an annual meeting by a shareholder, such business must be a proper matter for shareholder action pursuant to our By-Laws and under applicable law.

At a meeting of shareholders, the chairman of the Board may disregard any nomination or other proposal not made in compliance with the foregoing procedures.

To be timely, a written notice of the intent of a shareholder to make a nomination of a person for election as a director or to bring any other business before an annual meeting must be received by our Secretary at our principal executive offices not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the first anniversary of the date of the preceding year’s annual meeting of shareholders; provided, however, that if the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 60 days after such anniversary date, such advance notice shall be given by the later of:

If we call a special meeting of shareholders for the purpose of electing directors, notice of nominations must be delivered to our Secretary not later than the close of business on the 90th day prior to the date of such special meeting, or if later, the tenth day following the date on which public announcement is first made of the date of the special meeting and of the nominees proposed by the Board to be elected at such meeting.

(vi) the written consent of each proposed nominee to serve as a director if so elected.

(i) a description of the matter and the text of the proposal or business (including the text of any resolutions proposed for consideration and, in the event that such business includes a proposal to amend our By-Laws, the text of the proposed amendment);

10

(iii) any other information relating to such shareholder and beneficial owner, if any, on whose behalf the proposal is being made, required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for the proposal and pursuant to and in accordance with Section 14(a) of the Exchange Act.

(vii) a description of any agreement, arrangement or understanding (including any derivative or short positions, profit interests, options, hedging transactions, and borrowed or loaned shares) that has been entered into as of the date of the shareholder’s notice by, or on behalf of, the shareholder or any of its affiliates or associates, the effect or intent of which is to mitigate loss to, manage risk or benefit of share price changes for, or increase or decrease the voting power of the shareholder or any of its affiliates or associates with respect to our shares of stock; and

Exclusive Forum Provision of our By-Laws

Our By-Laws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for certain actions shall be the Seventh Judicial Circuit Court in and for Volusia County, Florida (or, if no state court located within the State of Florida has jurisdiction, the federal district court for the Middle District of Florida). Those actions include: (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors or our officers or other employees to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the FBCA or the Articles of Incorporation or By-Laws (as either may be amended from time to time) or (iv) any action asserting a claim governed by the internal affairs doctrine.

Amendments to By-Laws

Our By-Laws may be amended or repealed and additional By-Laws added or adopted by a majority vote of the entire Board so long as the proposed action is not inconsistent with any By-Laws which may have been adopted by any shareholders meeting by a vote of the majority of our issued and outstanding common stock. Our By-Laws may be amended or repealed at any shareholders meeting by a vote of the majority of the issued and outstanding common stock of the Company.

11

Amendment of the Articles of Incorporation

Our Articles of Incorporation provide that the Articles of Incorporation may be amended in the manner provided by law. Every amendment shall be approved by our Board, proposed by them to our shareholders, and approved at a shareholders meeting by a majority of the shares entitled to vote thereon, unless all directors and all shareholders sign a written statement manifesting their intention that a certain amendment of our Articles of Incorporation be made.
