SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference into this prospectus contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, which we refer to as the “Securities Act,” and Section 21E of the Securities Exchange Act of 1934, as amended, which we refer to as the “Exchange Act.” Such statements are based upon current expectations that involve risks and uncertainties. Any statements contained herein or in documents incorporated by reference that are not statements of historical fact may be deemed to be forward-looking statements. For example, words such as “may,” “will,” “should,” “estimates,” “predicts,” “possible,” “potential,” “continue,” “strategy,” “believes,” “anticipates,” “plans,” “expects,” “intends” and similar expressions are intended to identify forward-looking statements.

Our actual results and the outcome and timing of certain events may differ significantly from the expectations discussed in the forward-looking statements. Factors that might cause or contribute to such a discrepancy include, but are not limited to, the factors set forth below and may impact either or both of our operating segments:

The foregoing risks and uncertainties, as well as those risks and uncertainties referred to under the heading “Risk Factors” and those incorporated by reference herein, may cause actual results to differ materially from the forward-looking statements. The information included or incorporated by reference is given as of the respective dates of this prospectus or the documents incorporated by reference into this prospectus, and future events or circumstances could differ significantly from such information.

RISK FACTORS

In addition to the other information included in this prospectus, including the matters addressed under “Special Note on Forward-Looking Statements,” you should carefully consider the risk factors that are set forth in our most recent Annual Report on Form 10-K, and any updates to those risk factors or new risk factors included in subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are incorporated by reference into this prospectus, and the following risks.

The risks and uncertainties discussed below and in the documents referred to above, as well as other matters discussed in this prospectus and in those documents, could materially and adversely affect our businesses, financial condition, liquidity, results of operations, and prospects, and the market price of the Notes. Moreover, the risks and uncertainties discussed below and in the foregoing documents are not the only risks and uncertainties that we face, and our businesses, financial condition, liquidity and results of operations and the market price of the Notes could be materially adversely affected by other matters that are not known to us or that we currently do not consider to be material risks to our businesses.

Risks Related to the Notes

The Notes are structurally subordinated to the obligations of our subsidiaries and to all secured indebtedness, and this may limit our ability to satisfy our obligations under the Notes.

The Notes are our senior unsecured obligations and rank equally with each other and all of our other indebtedness that is not expressly subordinated to the Notes. The Notes are structurally subordinated to the obligations of our subsidiaries and to all of our secured indebtedness to the extent of the value of the collateral securing such indebtedness. As of June 30, 2018, we had outstanding approximately $1.3 billion principal amount of senior unsecured indebtedness (exclusive of intercompany debt, trade payables, distributions payable and accrued expenses). As of June 30, 2018, our subsidiaries had outstanding approximately $3.8 billion of other liabilities (including approximately $28.4 million of secured indebtedness).

We conduct substantially all of our operations through our subsidiaries. We do not have any material assets other than our direct and indirect ownership in the equity of our operating subsidiaries. As a result, our cash flow and our ability to service our debt, including the Notes, are dependent upon the earnings of our subsidiaries. In addition, we are dependent on the distribution of earnings, loans or other payments by our subsidiaries to us. Certain regulatory requirements and debt and security agreements entered into by our subsidiaries contain various restrictions, including restrictions on payments by our subsidiaries to us and the transfer by our subsidiaries of assets pledged as collateral. In the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding with respect to any of our subsidiaries, we, as an equity owner of such subsidiary, and therefore holders of our debt, including the Notes, will be subject to the prior claims of such subsidiary’s creditors, including trade creditors, and any preferred equity holders.

In the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding with respect to us, the holders of any secured indebtedness will be entitled to proceed directly against the collateral that secures such secured indebtedness. Therefore, such collateral will not be available for satisfaction of any amounts owed under our unsecured indebtedness, including the Notes, until such secured indebtedness is satisfied in full.

There are limited covenants and protections in the indenture and applicable supplemental indentures for the Notes.

While the indenture and the applicable supplemental indentures governing the Notes contain terms intended to provide protection to holders upon the occurrence of certain events involving significant corporate transactions, these terms are limited and may not be sufficient to protect an investment in the Notes. For example, there are no financial covenants in the indenture. As a result, we are not restricted under the terms of

6

the Notes from entering into transactions that could increase the total amount of our outstanding indebtedness, adversely affect our capital structure or our credit ratings or associated outlooks, or otherwise adversely affect the holders of the Notes.

As described under “Description of the Notes—Offer to Repurchase Upon a Change of Control Triggering Event,” upon the occurrence of a Change of Control Triggering Event holders are entitled to require us to repurchase their Notes at 101% of their principal amount. However, the definition of the term “Change of Control Triggering Event” is limited and does not cover a variety of transactions (such as acquisitions by us, recapitalizations or “going private” transactions by our affiliates) that could negatively affect the value of the Notes. A change of control transaction under the supplemental indentures may only occur if there is a change in the controlling interest in us. For a Change of Control Triggering Event to occur there must be not only a change of control transaction as defined in the supplemental indentures, but also a ratings downgrade resulting from such transaction. If we were to enter into a significant corporate transaction that negatively affects the value of the Notes, but would not constitute a Change of Control Triggering Event, holders would not have any rights to require us to repurchase the Notes prior to their maturity, which also would adversely affect their investment.

Ratings of the Notes may not reflect all risks of an investment in the Notes, and changes in our credit ratings or associated outlooks could adversely affect the market price of the Notes.

Our long-term debt is currently rated by nationally recognized statistical rating organizations. A debt rating is not a recommendation to purchase, sell or hold the Notes. Moreover, a debt rating does not reflect all risks of an investment in the Notes and does not take into account market price or suitability for a particular investor.

The market price for the Notes is based on a number of factors, including our ratings and associated outlooks with major rating agencies. Rating agencies revise their ratings and associated outlooks for the companies that they follow from time to time, and our ratings and associated outlooks may be revised or withdrawn in their entirety at any time. We cannot be sure that rating agencies will maintain their current ratings and associated outlooks. We undertake no obligation to maintain the ratings and associated outlooks or to advise holders of the Notes of any change in ratings or associated outlooks. A negative change in our ratings or associated outlooks could have an adverse effect on the market price or liquidity of the Notes.

Changes in the credit markets could adversely affect the market price of the Notes.

The market prices for the Notes are based on a number of factors, including:

The condition of the credit markets and prevailing interest rates have fluctuated in the past and can be expected to fluctuate in the future. Fluctuations in these factors could have an adverse effect on the price and liquidity of the Notes.

There may not be an active trading market for the Notes, which could adversely affect the price of the Notes in the secondary market and your ability to resell the Notes should you desire to do so.

We do not intend to apply for listing of the Notes on any securities exchange, and there may not be an active trading market for any of the Notes.

We cannot make any assurance as to:

7

Neither CF&Co., nor any of our other affiliates, has any obligation to make a market in our Notes, and CF&Co. or any such other affiliate may discontinue market-making activities at any time without notice.

The trading market for and the future market prices of the Notes will depend on many factors, including prevailing interest rates, our credit ratings and associated outlooks published by the rating agencies that rate our indebtedness, the market for similar securities and our operating performance and financial condition. If an active trading market for the Notes does exist, there is no assurance that it will continue. If an active trading market for the Notes does not exist or does not continue, the market price and liquidity of the Notes are likely to be adversely affected, and Notes traded after their purchase may trade at a discount from their purchase price.

We may not be able to repurchase the Notes upon a Change of Control Triggering Event.

Upon the occurrence of a Change of Control Triggering Event (as defined in “Description of the Notes—Offer to Repurchase Upon a Change of Control Triggering Event”), unless we have exercised our right to redeem the notes as described under “Description of the Notes—Optional Redemption,” holders of Notes will have the right to require us to repurchase all or any part of their Notes at a price in cash equal to 101% of the then-outstanding aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to, but excluding, the date of purchase. If we experience a Change of Control Triggering Event, we can offer no assurance that we would have sufficient financial resources available to satisfy our obligations to repurchase any or all of the Notes should any holder elect to cause us to do so. Our failure to repurchase the Notes as required would result in a default under the indenture, which in turn could result in defaults under agreements governing certain of our other indebtedness, including the acceleration of the payment of any borrowings thereunder, and have material adverse consequences for us and the holders of the Notes.

USE OF PROCEEDS

We will not receive any of the proceeds from the market-making activities in our Notes by CF&Co. (or any of our other affiliates) pursuant to this prospectus.

RATIO OF EARNINGS TO FIXED CHARGES

The following table presents the ratio of earnings to fixed charges for us and our consolidated subsidiaries for each of the periods indicated, including GFI beginning on February 27, 2015. This table has been recast to include the financial results of Berkeley Point beginning on April 10, 2014 (the date Berkeley Point was acquired by CCRE).

For the purposes of calculating the ratio of earnings to fixed charges, “Earnings” consist of income from operations before income taxes and fixed charges, net. “Fixed charges” consist of interest expense incurred on all indebtedness, amortized premiums, discounts and capitalized expenses relating to indebtedness and interest within rental expense.

DESCRIPTION OF THE NOTES

We issued the Notes under an indenture, dated as of June 26, 2012, that we, as issuer, entered into with U.S. Bank National Association, as trustee (the “Trustee”), as supplemented, in the case of the 2019 Notes, by the Second Supplemental Indenture, dated as of December 9, 2014, in the case of the 2021 Notes, by the Third Supplemental Indenture, dated as of May 27, 2016, and in the case of the 2023 Notes, by the Fourth Supplemental Indenture, dated as of July 24, 2018. The aforementioned indenture and each of the aforementioned supplemental indentures have been filed as exhibits to the registration statement of which this prospectus is a part. The statements made in this section relating to the Notes are summaries of the material provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Notes, such indenture and the applicable supplemental indentures, including the definitions therein of certain terms. You should read these documents carefully to fully understand the terms of the Notes because they, and not this description, will define your rights as holders of the Notes.

Capitalized terms used but not otherwise defined herein shall have the meanings given to them in the Notes, indenture, or applicable supplemental indentures, as applicable. In this description, the terms the “Company,” “we,” “us” and “our” refer only to BGC Partners, Inc. and not to any of its subsidiaries.

The registered holder of a Note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture and applicable supplemental indenture.

Each of the 2019 Notes, 2021 Notes, and 2023 Notes is referred to as a “series of Notes” or the “Notes” herein.

General

The Notes are our senior unsecured obligations and rank equally in right of payment with all of our other senior unsecured indebtedness from time to time outstanding. The 2019 Notes, 2021 Notes, and 2023 Notes will mature on December 9, 2019, May 27, 2021 and July 24, 2023, respectively, unless previously redeemed or repurchased in full by us as provided below under “—Optional Redemption” or “—Offer to Repurchase Upon a Change of Control Triggering Event.”

The 2019 Notes bear interest at the rate of 5.375% per annum from December 9, 2014, to the stated maturity or date of earlier redemption. Interest on the 2019 Notes is payable semi-annually in arrears on each June 9 and December 9, commencing on June 9, 2015, to the persons in whose names such 2019 Notes were registered at the close of business on the immediately preceding May 25 and November 25 (whether or not a business day), respectively. See “—Interest Rate Adjustment Based on Rating Events” below for a description of how the interest rate of the 2019 Notes is subject to certain adjustments.

The 2021 Notes bear interest at the rate of 5.125% per annum from May 27, 2016, to the stated maturity or date of earlier redemption. Interest on the 2021 Notes is payable semi-annually in arrears on each May 27 and November 27, commencing on November 27, 2016, to the persons in whose names such 2021 Notes were registered at the close of business on the immediately preceding May 12 and November 12 (whether or not a business day), respectively.

The 2023 Notes bear interest at the rate of 5.375% per annum from July 24, 2018, to the stated maturity or date of earlier redemption. Interest on the 2023 Notes is payable semi-annually in arrears on each January 24 and July 24, commencing on January 24, 2019, to the persons in whose names such 2023 Notes were registered at the close of business on the immediately preceding January 9 and July 9 (whether or not a business day), respectively. See “—Interest Rate Adjustment Based on Rating Events” below for a description of how the interest rate of the 2023 Notes is subject to certain adjustments.

10

Interest payments in respect of the Notes will equal the amount of interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or duly provided for (or from and including the date of issue, if no interest has been paid or duly provided for with respect to the Notes), to, but excluding, the applicable interest payment date or stated maturity date or date of early redemption, as the case may be. Interest on the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. The principal and interest (including any additional interest), if any, on the Notes will be payable through The Depository Trust Company, which we refer to as the “Depository,” as described under “—Same-Day Funds Settlement and Payment.”

If an interest payment date or the stated maturity date or date of early redemption of the Notes falls on a Saturday, Sunday or other day on which banking institutions in The City of New York are authorized or obligated by law or executive order to close, the required payment due on such date will instead be made on the next business day. No further interest will accrue as a result of such delayed payment.

We issued the 2019 Notes, 2021 Notes, and 2023 Notes initially in aggregate principal amounts of $300.0 million, $300.0 million and $450.0 million, respectively. The indenture does not limit the aggregate principal amount of the debt securities which we may issue thereunder and provides that we may issue debt securities thereunder from time to time in one or more series. We may, from time to time, without the consent of or notice to holders of the Notes, issue and sell additional debt securities ranking equally and ratably with any series of the Notes in all respects and having the same terms as the applicable series (other than the issue date, and to the extent applicable, issue price, initial date of interest accrual and initial interest payment date of such additional debt securities), so that such additional debt securities shall be consolidated and form a single series with the applicable series for all purposes, including voting; provided, that such additional debt securities are fungible with the previously issued Notes of the applicable series for U.S. federal income tax purposes.

We have agreed in the supplemental indentures to use the net proceeds from the initial offering of the Notes, after deducting the initial purchasers’ discount and expenses paid by us in connection with such offering of the Notes, to make loans to our subsidiaries pursuant to one or more promissory notes. So long as Notes of a particular series are outstanding, (1) the aggregate principal amount of all such promissory notes shall be not less than the amount of the net proceeds from the offering of the Notes of such series (or if less, the aggregate principal amount of Notes of such series then outstanding), (2) such promissory notes shall bear interest at rates that shall not be less than that borne by the Notes of such series and (3) such promissory notes shall have terms not later than the stated maturity date of the Notes of such series; provided, that any transfer of such obligation from one subsidiary to another or any refinancing of any such obligation by another subsidiary shall be permitted from time to time. We further agreed that for so long as the Notes of such series remain outstanding, any indebtedness for borrowed money we incur after the date of original issuance of the Notes of such series in one transaction, or in a series of related transactions, that is in excess of $25.0 million will be subject to a similar covenant.

The Notes have been issued only in fully registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes may be presented for transfer (duly endorsed or accompanied by a written instrument of transfer, if so required by us or the security registrar) or exchanged for other notes (containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount) at the office or agency maintained by us for such purposes (initially the corporate trust office of the Trustee). Such transfer or exchange will be made without service charge, but we may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses then payable. Prior to the due presentment of a Note for registration of transfer, we, the Trustee and any other agent of ours or the Trustee may treat the registered holder of each Note as the owner of such Note for the purpose of receiving payments of principal of and interest on such Note and for all other purposes whatsoever.

Except as described below under “—Offer to Repurchase Upon a Change of Control Triggering Event” and “—Interest Rate Adjustment Based on Rating Events,” the indenture does not contain any provisions that would

11

limit our ability to incur unsecured indebtedness or that would afford holders of the Notes protection in the event of a sudden and significant decline in our credit quality or a takeover, recapitalization or highly leveraged or similar transaction involving us. Accordingly, we could in the future enter into transactions that could increase the amount of indebtedness outstanding at that time or otherwise affect our capital structure or credit rating.

The Notes are not entitled to the benefit of any mandatory redemption or sinking fund.

Optional Redemption

At any time and from time to time, we will be entitled at our option to redeem any series of the Notes, in whole or in part, at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the Notes to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments (as defined below) for such series of Notes, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date, subject to the rights of holders of the Notes to be redeemed on the relevant record date to receive interest due on the relevant interest payment date.

In determining the present values of the Remaining Scheduled Payments of the series of Notes to be redeemed, we will discount such payments to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus, in case of the 2019 Notes and the 2021 Notes, 50 basis points, and in the case of the 2023 Notes, 45 basis points.

The following terms are relevant to the determination of the redemption price:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the series of 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, (1) the arithmetic average of the applicable Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest Reference Treasury Dealer Quotations, (2) if the Company obtains fewer than four applicable Reference Treasury Dealer Quotations, the arithmetic average of all applicable Reference Treasury Dealer Quotations for such redemption date or (3) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means one of the Reference Treasury Dealers, or their respective successors, as may be appointed from time to time by the Company; provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in the United States (a “primary treasury dealer”), we will substitute another primary treasury dealer.

“Reference Treasury Dealer” means, (i) in the case of the 2019 Notes, Morgan Stanley & Co. LLC and three other primary treasury dealers selected by the Company, and each of their respective successors and any other primary treasury dealers selected by the Company, and (ii) in the case of the 2021 and 2023 Notes, Merrill Lynch, Pierce, Fenner & Smith Incorporated and three other primary treasury dealers selected by the Company, and each of their respective successors and any other primary treasury dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer as of 3:30 p.m., New York City time, on the third business day preceding such redemption date.

12

“Remaining Scheduled Payments” means, with respect to any Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Note, the amount of the next scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the applicable Comparable Treasury Issue. In determining this rate, the Company will assume a price for the applicable Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date.

Offer to Repurchase 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, holders of Notes will have the right to require us to repurchase all or any part (in minimum original principal amounts of $2,000 and integral multiples of $1,000 in excess thereof) of their Notes pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the Notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the then outstanding aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to, but not including, the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, we will be required to mail a notice to holders of Notes (with a copy to the Trustee) describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Notes on the 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 “Change of Control Payment Date”), pursuant to the procedures required by the Notes and the supplemental indentures and described in such notice. We must comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, we will be required to 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 conflicts.

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

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

The change of control feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of us and, thus, the removal of incumbent management. We could, in the future, enter into

13

certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Notes, but that could increase the amount of our indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings on the Notes.

For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:

“Below Investment Grade Rating Event” means that both Rating Agencies (as defined below) shall have ceased to rate the Notes at an Investment Grade Rating on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by the Company of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as either of the Rating Agencies has publicly announced that it is considering a possible ratings change). If a Rating Agency is not providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated an Investment Grade Rating by such Rating Agency during that Trigger Period.

A “Change of Control” will be deemed to have occurred at such time after the original issuance of the Notes when any of the following has occurred:

(1) a “person” or “group” within the meaning of Section 13(d) of the Exchange Act other than us, our subsidiaries, our and their respective employee benefit plans and any Permitted Holder, has become the direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of our capital stock representing, in the aggregate, more than 50% of the voting power of all classes of our capital stock; or

(2) one or more Permitted Holders shall cease to (i) own and control, beneficially, capital stock of ours that possesses the voting power under normal circumstances to cast 50% or more of the total votes entitled to be cast for the election of directors of ours; or (ii) have the voting power or the contractual right to elect a majority of our directors; or

(3) our liquidation or dissolution or the stockholders of the Company approve any plan or proposal for our liquidation or dissolution; or

(4) any conveyance, transfer, sale, lease or other disposition of all or substantially all of the properties and assets of ours to another person, other than:

(i) that does not result in any reclassification, conversion, exchange or cancellation of our outstanding equity interests; or

(ii) pursuant to which holders of our outstanding equity interests, immediately prior to the transaction, have the entitlement to exercise, directly or indirectly, 50% or more of the total voting power of all equity interests entitled to vote generally in elections of directors or managers of the continuing or surviving or successor entity immediately after giving effect to such issuance; or

Notwithstanding the foregoing, no Change of Control will be deemed to have occurred in the event any successor issuer of the Notes shall be a corporation so long as one or more Permitted Holders shall maintain the

14

beneficial ownership of shares of the capital stock of such successor possessing the voting power under normal circumstances to elect, or one or more Permitted Holders shall have the contractual right to elect, a majority of the directors of such successor corporation. Notwithstanding the foregoing, a transaction will not be deemed to result in a Change of Control if (a) Cantor Fitzgerald, L.P. becomes a wholly owned subsidiary of a holding company and (b) the holders of the voting capital stock of such holding company immediately following that transaction are substantially the same as the holders of Cantor Fitzgerald, L.P.’s voting partnership interests immediately prior to that transaction.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Fitch” means Fitch Ratings.

“Investment Grade Rating” means a rating equal to or higher than BBB- (or the equivalent) by Fitch or BBB- (or the equivalent) by S&P.

“Permitted Holder” means Howard W. Lutnick, any Person controlled by him or any trust established for Mr. Lutnick’s benefit or for the benefit of his spouse, any of his descendants or any of his relatives, in each case, so long as he is alive and, upon his death or incapacity, any person who shall, as a result of Mr. Lutnick’s death or incapacity, become a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of the Company’s capital stock by operation of a trust, by will or the laws of descent and distribution or by operation of law.

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

“Rating Agencies” means (1) each of Fitch and S&P; and (2) if either of Fitch or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of the Exchange Act, selected by us (as certified by a resolution of our Board of Directors) as a replacement agency for Fitch or S&P, or both of them, as the case may be.

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc.

Interest Rate Adjustment Based on Rating Events

The interest rate payable on the 2019 Notes and the 2023 Notes—but not the 2021 Notes—will be subject to adjustments from time to time if each of Fitch and S&P downgrades (or subsequently upgrades) the debt rating assigned to such series of Notes, in the manner described below.

If the rating from each of Fitch and S&P of the 2019 Notes or the 2023 Notes is decreased to a rating set forth in the immediately following table (a “Downgrade Event”), the interest rate on such series of Notes will increase such that it will equal the interest rate payable on such series of Notes on the date of the initial issuance thereof plus the percentage set forth opposite the applicable rating from the table below:

For the avoidance of doubt, any increase in the interest payable on the 2019 Notes or the 2023 Notes shall require a decrease in the rating of such series of Notes by each of Fitch and S&P to the relevant threshold ratings set forth above.

15

If, subsequent to a Downgrade Event, either of Fitch or S&P increases its respective rating of the 2019 Notes or the 2023 Notes to any of the threshold ratings set forth above, the interest rate on such series of Notes will be decreased such that the interest rate for such series of Notes equals the interest rate payable on such series of Notes on the date of the initial issuance thereof plus the percentage set forth opposite the applicable rating from the table above. For the avoidance of doubt, any decrease in the interest payable on the 2019 Notes or the 2023 Notes shall require an increase in the rating of such series of Notes by only one of Fitch and S&P to relevant threshold ratings set forth above.

For so long as (i) only one of Fitch or S&P provides a rating of the 2019 Notes or the 2023 Notes or (ii) such series of Notes are not rated by either Fitch or S&P, the interest rate on such series of Notes will increase such that it will equal the interest rate payable on such series of Notes on the date of the initial issuance thereof plus 1.00%.

Any interest rate increase or decrease described above will take effect from the first day of the interest period during which a rating change requires an adjustment in the interest rate. If Fitch or S&P changes its rating of the 2019 Notes or the 2023 Notes more than once during any particular interest period, the last change by Fitch or S&P, as applicable, will control for purposes of any interest rate increase or decrease with respect to such series of Notes described above relating to Fitch’s or S&P’s, as applicable, action. We will communicate an increase or decrease to the Trustee in the form of an officers’ certificate under the indenture.

If the interest rate payable on the 2019 Notes or the 2023 Notes is increased as described above, the term “interest,” as used with respect to such series of Notes, will be deemed to include any such additional interest unless the context otherwise requires.

For the avoidance of doubt, the provisions described in this “Interest Rate Adjustment Based on Rating Events” shall not apply to the 2021 Notes.

Certain Covenants

Limitations on Liens on Stock of Subsidiaries

Under the supplemental indentures, we covenant that, so long as any of the Notes are outstanding, we will not, and will not permit any Designated Subsidiary (other than, in the case of the 2023 Notes only, Newmark or any of its subsidiaries) to, create, assume, incur, guarantee or otherwise permit to exist any Indebtedness secured by any mortgage, pledge, lien, security interest or other encumbrance (a “lien”) upon any shares of capital stock of any Designated Subsidiary (including, in the case of the 2023 Notes, the capital stock of Newmark held by us) directly or indirectly held by us (whether such capital stock is now owned or hereafter acquired) without effectively providing concurrently that the Notes (and, if we so elect, any other Indebtedness of ours that is not subordinate to the Notes and with respect to which the governing instruments of such Indebtedness require, or pursuant to which we are otherwise obligated, to provide such security) will be secured equally and ratably with, or prior to, such Indebtedness for at least the time period such other Indebtedness is so secured. The foregoing will not apply to liens on the securities of any entity existing at the time it becomes a Designated Subsidiary (and any extensions, renewals or replacements thereof).

For purposes of the indenture, “capital stock” of any Person means any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interests in (however designated) equity of such Person, including preferred stock, but excluding any debt securities convertible into such equity.

For purposes of the supplemental indentures, the term “Designated Subsidiary” means each of (i) BGC Holdings, L.P. (“BGC Holdings”), (ii) BGC Global Holdings, L.P. (“BGC Global”), (iii) BGC Partners, L.P. (“BGC US”), and (iv) any other direct or indirect subsidiary now owned or hereafter acquired by us for which (a) the Net Assets constitute, as of the last day of the most recently ended fiscal quarter, 5% or more of our Total

16

Stockholders’ Equity or (b) the net revenues constitute, as of the last day of the most recently ended fiscal quarter, 10% or more of the consolidated net revenues of ours during the most recently ended period of four consecutive fiscal quarters; provided, however, that the following shall not be Designated Subsidiaries:

The term “Indebtedness” means, without duplication, with respect to any Person, whether or not contingent:

if and to the extent any of the preceding items (other than letters of credit) would appear as a liability upon a balance sheet of such Person prepared in accordance with U.S. GAAP; provided, however, the term “Indebtedness” includes all of the following items, whether or not any such items would appear as a liability on a balance sheet of such Person prepared in accordance with generally accepted accounting principles:

The term “Net Assets” means, with respect to any Person, the excess (if positive) of (a) such Person’s consolidated assets over (b) such Person’s consolidated liabilities, in each case determined in accordance with U.S. GAAP.

The term “Total Stockholders’ Equity” means, as of the date of determination, without duplication, all items which in conformity with U.S. GAAP would be included under total stockholders’ equity on our consolidated statement of financial condition. For purposes of any determination of total stockholders’ equity, we may include the amount of any capital to be returned pursuant to the terms of the Amended and Restated Agreement of Limited Partnership of BGC Holdings, as amended from time to time, to any limited or general partner who has been terminated or withdrawn until such time as the amount of such partners’ capital has been paid to such limited or general partner pursuant to the terms of such Partnership Agreement plus, without duplication, redeemable partnership interests representing former partner’s equity in us. For the avoidance of doubt, Total Stockholders’ Equity is inclusive of non-controlling interests in subsidiaries on our consolidated statement of financial condition.

17

Consolidation, Merger or Sale

We may not consolidate or merge with or into, or transfer or lease all or substantially all of our assets to, any Person unless either (a) we will be the continuing entity or (b) the successor entity or Person to which our assets are transferred or leased is an entity organized under the laws of the United States, any state of the United States or the District of Columbia and it expressly assumes our obligations on the Notes and under the indenture. In addition, we cannot effect such a transaction unless immediately after giving effect to such transaction, no default or event of default under the indenture shall have occurred and be continuing. Subject to certain exceptions, when the Person to whom our assets are transferred or leased has assumed our obligations under the Notes and the indenture, we will be discharged from all our obligations under the Notes and the indenture, except in limited circumstances.

This covenant does not apply to any recapitalization transaction, a change of control of us or a highly leveraged transaction, unless the transaction or change of control were structured to include a merger or consolidation or transfer or lease of all or substantially all of our assets.

Modification, Amendment or Waiver

We may from time to time amend or supplement the indenture with respect to any series of Notes and the Notes of such series without the consent of registered holders of such series to, among other things, (i) modify the restrictions on and procedures for resale, attempted resale, and other transfers of the Notes of such series or interests therein to reflect any change in applicable law or regulation (or interpretation thereof) or in practices relating to the resale or transfer of restricted securities generally or (ii) to cure any ambiguity or defect in and to correct or supplement any provision of the indenture or any Note of such series that may be inconsistent with any other provision in the indenture or the Notes of such series, provided, however, that any such cure, correction or supplement shall not adversely affect the interests of the holders of the Notes of such series in any material respect.

With certain exceptions, we may make modifications and amendments of the indenture with respect to any series of Notes with the consent of the registered holders of not less than a majority in aggregate principal amount of the Notes of such series. Compliance with certain covenants may be waived on behalf of registered holders of Notes of a series, either generally or in a specific instance and either before or after the time for compliance with those covenants, with the consent of holders of not less than a majority in aggregate principal amount of the then outstanding Notes of such series. Nevertheless, without the consent of each registered holder of the Notes affected thereby, no such modification or amendment may, among other things, reduce the principal of or interest on any of the outstanding Notes, extend the stated maturity of the Notes, change the interest payment dates or terms of payment for the Notes, or reduce the percentage of registered holders necessary to modify or amend the indenture and the Notes.

Events of Default

Unless otherwise indicated, the term “Event of Default,” when used in the indenture and supplemental indentures with respect to each of the 2019 Notes, the 2021 Notes, and the 2023 Notes means any of the following:

18

If an Event of Default relating to the payment of interest (including any additional interest) or principal with respect to the Notes of a series has occurred and is continuing, the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes of such series may declare the entire principal of the Notes of such series to be due and payable immediately.

If an Event of Default relating to the performance of other covenants occurs and is continuing, then the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes of a series may declare the entire principal amount of the Notes of such series to be due and payable immediately.

The holders of not less than a majority in aggregate principal amount of the Notes of a series may, after satisfying conditions, rescind and annul any of the above-described declarations and consequences.

If an Event of Default relating to events of our bankruptcy, insolvency, reorganization or liquidation occurs and is continuing, then the principal amount of the Notes outstanding, and any accrued interest. will automatically become due and payable immediately, without any declaration or other act by the Trustee or any holder.

The indenture imposes limitations on suits brought by holders of Notes against us. Except as provided below, no holder of Notes of a series may institute any action against us under the indenture unless:

Notwithstanding the foregoing, each holder of Notes of any series has the right, which is absolute and unconditional, to receive payment of the principal of, and premium and interest, if any, on, the Notes when due and to institute suit for the enforcement of any such payment, and such rights may not be impaired without the consent of that holder of Notes.

We will be required to file annually with the Trustee a certificate, signed by an officer of the Company, stating whether or not the officer knows of any default by us in the performance, observance or fulfillment of any condition or covenant of the indenture.

Discharge, Defeasance and Covenant Defeasance

We can discharge or defease our obligations under the indenture with respect to any series of Notes and the Notes of such series as set forth below.

19

We may discharge our obligations to holders of Notes of any series that have not already been delivered to the Trustee for cancellation and that have become due and payable within one year (or are scheduled for redemption within one year). We may effect a discharge by irrevocably depositing with the Trustee cash or U.S. government obligations, as trust funds, in an amount certified to be sufficient to pay when due, whether at maturity, upon redemption or otherwise, the principal of, and premium, if any, and interest on, the Notes of such series.

We may also discharge any and all of our obligations to holders of Notes of any series at any time (“legal defeasance”). We also may be released from the obligations imposed by any covenants of any series of Notes and provisions of the indenture with respect to such series of Notes, and we may omit to comply with those covenants without creating an Event of Default with respect to such series of Notes (“covenant defeasance”). We may effect legal defeasance and covenant defeasance only if, among other things:

Although we may discharge or defease our obligations under the indenture as described in the two preceding paragraphs, we may not avoid, among other things, our duty to register the transfer or exchange of any Notes, to replace any temporary, mutilated, destroyed, lost or stolen Notes or to maintain an office or agency in respect of the Notes.

Book-Entry System

The certificates representing the Notes of each series have been issued in the form of one or more fully-registered global notes without coupons (each, a “Global Note”) and have been deposited with, or on behalf of, the Depository and registered in the name of Cede & Co., as the nominee of the Depository. Except in limited circumstances, the Notes are not issuable in definitive form. Unless and until they are exchanged in whole or in part for the individual Notes represented thereby, any interests in a Global Note may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any nominee of the Depository to a successor depository or any nominee of such successor.

The Depository is under no obligation to provide its services as depository for the certificates of any series of Notes and may discontinue providing its services at any time. Neither we nor the Trustee will have any responsibility for the performance by the Depository or its direct or indirect participants under the rules and procedures governing the Depository. As noted above, owners of beneficial interests in a Global Note will not receive certificates representing their interests. However, we will prepare and deliver certificates for the Notes of that series in exchange for beneficial interests in a Global Note if:

20

Any beneficial interest in a Global Note that is exchangeable under the circumstances described in the preceding sentence will be exchangeable for Notes in definitive certificated form registered in the names that the Depository shall direct. It is expected that these directions will be based upon directions received by the Depository from its participants with respect to ownership of beneficial interests in the Global Note.

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

Conveyance of notices and other communications by the Depository to Direct Participants, by Direct Participants to indirect participants and by direct and indirect participants to beneficial owners will be governed by arrangements among them, subject to any legal requirements in effect from time to time.

Redemption notices shall be sent to the Depository or its nominee. If less than all of the Notes of a series are being redeemed, the Depository will reduce the amount of the interest of Direct Participants in such Notes in accordance with its procedures.

A beneficial owner of Notes of a series shall give written notice to elect to have its Notes repurchased or tendered, through its participant, to the Trustee and shall effect delivery of such Notes by causing the Direct Participant to transfer the participant’s interest in such Notes, on the Depository’s records, to the Trustee. The requirement for physical delivery of Notes in connection with a repurchase or tender will be deemed satisfied when the ownership rights in such Notes are transferred by Direct Participants on the Depository’s records and followed by a book-entry credit of such Notes to the Trustee’s Depository account.

In any case where a vote may be required with respect to the Notes of any series, neither the Depository nor Cede & Co. will give consents for or vote such global debt securities. Under its usual procedures, the Depository will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those Direct Participants to whose accounts the Notes are credited on the record date identified in a listing attached to the omnibus proxy.

Principal of and premium, if any, and interest, if any, on a Global Note will be paid to Cede & Co., as nominee of the Depository. The Depository’s practice is to credit Direct Participants’ accounts on the relevant payment date unless the Depository has reason to believe that it will not receive payments on the payment date.

21

Payments by direct and indirect participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in “street name.” Those payments will be the responsibility of participants and not of the Depository or us, subject to any legal requirements in effect from time to time. Payment of principal, premium, if any, and interest, if any, to Cede & Co. is our responsibility, disbursement of payments to Direct Participants is the responsibility of the Depository, and disbursement of payments to the beneficial owners is the responsibility of direct and indirect participants.

The rules applicable to the Depository and its Direct Participants are on file with the SEC. The information in this section concerning the Depository and the Depository’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Same-Day Funds Settlement and Payment

All payments of principal, premium if any, and interest in respect of Notes in book-entry form will be made by us in immediately available funds to the accounts specified by the Depository.

Governing Law

The indenture, supplemental indentures and the Notes are governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made or instruments entered into and, in each case, performed in that state.

Concerning the Trustee

U.S. Bank National Association is the Trustee under the indenture with respect to the Notes and also serves as the registrar and paying agent. We maintain corporate trust relationships in the ordinary course of business with the Trustee.

Registration Rights Agreement

Affiliates of Cantor currently hold approximately $15 million aggregate principal amount of the $300 million outstanding aggregate principal amount of the 2021 Notes. The Notes held by the Cantor affiliates were acquired from us in the initial offering of the Notes, and such Cantor affiliates are our affiliates also. Pursuant to a Registration Rights Agreement, dated as of May 27, 2016, by and between us and the other parties named therein, such Cantor affiliates, and their respective transferees, have the right to require us to file a resale registration statement to enable them to sell the Notes that they hold.

22

PLAN OF DISTRIBUTION

This prospectus may be used by CF&Co., our affiliate, in connection with offers and sales of the Notes in ongoing market-making transactions in the Notes. Market-making transactions may occur in the open market or may be privately negotiated at prevailing market prices at the time of sale or at related or negotiated prices. In these transactions, CF&Co. may act as principal or agent, including as agent for the counterparty in a transaction in which CF&Co. acts as principal, or as agent for both counterparties in a transaction in which CF&Co. does not act as principal. CF&Co. may receive compensation in the form of discounts and commissions, including from both counterparties in some cases. Other affiliates of ours may also engage in market-making transactions of this kind and may use this prospectus for that purpose. CF&Co., or any of our other affiliates, will conduct these offers and sales in compliance with the requirements of the Financial Industry Regulatory Authority (“FINRA”), including FINRA Rule 5121, regarding a FINRA member firm’s offers and sales of securities of an affiliate and related conflicts of interest. CF&Co., or any of our other affiliates, may not make sales to any discretionary account pursuant to this prospectus unless it has received prior specific written approval of the transaction from the discretionary account holder.

The 2021 Notes in the aggregate principal amount of approximately $15.0 million held by Cantor affiliates that were acquired from us in the initial offering of such 2021 Notes (Cusip No. 05541T AG6) will be covered by this market-making prospectus only after they are resold to non-affiliates of Cantor and us pursuant to a resale registration statement, or otherwise become freely tradable in the hands of transferees. The 2023 Notes in the aggregate principal amount of $250,000 that were acquired from us in the initial offering of such 2023 Notes (CUSIP No. 05541T AJ10) and not tendered to us by the holders thereof in our exchange offer registered on Form S-4 completed on September 17, 2018 will be covered by this market­making prospectus only after they are freely tradable in the hands of the holder.

We will not receive any proceeds from these market-making transactions.

Information about the trade and settlement dates, as well as the purchase price, for a market-making transaction will be provided to the purchaser in a separate confirmation of sale.

Neither CF&Co., nor any of our other affiliates, has any obligation to make a market in the Notes, and CF&Co., or any such other affiliate, may discontinue market-making activities at any time without notice.

PART II

Information Not Required in Prospectus

The following table sets forth the costs and expenses payable in connection with the offering of the securities being registered, all of which will be paid by BGC Partners, Inc. (the “Registrant”). All amounts are estimates except the Securities and Exchange Commission (the “SEC”) registration fee.

Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent of the Registrant. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaws, agreement, vote of stockholders or disinterested directors or otherwise. The Registrant’s Restated Certificate of Incorporation and Amended and Restated Bylaws provide for indemnification by the Registrant of its directors and officers to the fullest extent permitted by the DGCL.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (4) for any transaction from which the director derived an improper personal benefit. The Registrant’s Restated Certificate of Incorporation provides for such limitation of liability to the fullest extent permitted by the DGCL.

The Registrant maintains standard policies of insurance under which coverage is provided (1) to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, while acting in their capacity as directors and officers of the Registrant, and (2) to the Registrant with respect to payments which may be made by the Registrant to such directors and officers pursuant to any indemnification provision contained in the Registrant’s Restated Certificate of Incorporation and Amended and Restated Bylaws or otherwise as a matter of law.

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

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

provided, however, that:

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

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

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

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

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

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

incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

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

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