Motorola Solutions, Inc.

4.600% Senior Notes due 2028

We are offering an additional $200,000,000 in aggregate principal amount of our 4.600% Senior Notes due 2028 (the “notes”).

We previously issued notes of this series in an aggregate principal amount of $500,000,000 on February 23, 2018, which we refer to as the existing notes. Accordingly, the notes offered by this prospectus supplement and the accompanying prospectus will:

The notes will bear interest at the rate of 4.600% per year. Interest on the notes is payable on February 23 and August 23 of each year, beginning on February 23, 2019. The notes will mature on February 23, 2028. The notes will be our unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness from time to time outstanding. We will issue the notes in minimum denominations of $2,000 and integral multiples of $1,000.

We may redeem all or a portion of the notes at any time at the redemption prices described in this prospectus supplement. Upon the occurrence of a “change of control repurchase event,” we will be required to make an offer to repurchase the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to, but not including, the date of repurchase.

The notes are not and will not be listed on any securities exchange.

Investing in these securities involves certain risks. See “Risk Factors” beginning on page S-9 of this prospectus supplement and page 3 of the accompanying prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved the notes or determined that this prospectus supplement or the accompanying prospectus is accurate or complete. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the notes in book-entry form only through the facilities of The Depository Trust Company and its participants, Clearstream Banking societé anonyme and the Euroclear Bank S.A./N.V., on or about October 5, 2018, which is the fifth business day following the date of this prospectus supplement.

RISK FACTORS

Investing in the notes involves risk. We are subject to various regulatory, operating and other risks as a result of the nature of our operations and the marketplace in which we operate. Many of these risks are beyond our control and several pose significant challenges to our business, operations, revenues, net income and cash flows. These risks are described in Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended December 31, 2017 as well as Part II, Item 1A, Risk Factors, of our Quarterly Report on Form 10-Q for the period ended June 30, 2018. The risks described therein are not the only ones we face. Additional risks of which we are not presently aware or that we currently believe are immaterial may also harm our business. In deciding whether to invest in the notes, you should carefully consider these risks and the risks described below in addition to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. Our business, results of operations and financial condition may be materially adversely affected due to any of these risks or events arising therefrom.

Risks Related to the Notes

Because the notes are not secured and are effectively subordinated to the rights of secured creditors, the notes will be subject to the prior claims of any secured creditors, and if a default occurs, we may not have sufficient funds to fulfill our obligations under the notes.

The notes are unsecured obligations, ranking equally with other senior unsecured indebtedness. Although we currently only have immaterial amounts of secured indebtedness at the foreign subsidiary level, the indenture governing the notes permits us to incur secured debt under specified circumstances. If we incur secured debt, our assets will be subject to prior claims by our secured creditors. In the event of bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding up of Motorola Solutions, assets that secure debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in any remaining assets ratably with all of their respective unsecured and unsubordinated creditors, including trade creditors. If Motorola Solutions incurs any additional obligations that rank equally with the notes, including trade payables, the holders of those obligations will be entitled to share ratably with the holders of the notes in any proceeds distributed upon our bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding up. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all these creditors, all or a portion of the notes then outstanding would remain unpaid.

We may depend on the receipt of dividends or other intercompany transfers from our subsidiaries to meet our obligations under the notes. Claims of creditors of our subsidiaries will have priority over your claims with respect to the assets and earnings of our subsidiaries.

The notes are our obligations exclusively and not of any of our subsidiaries. We conduct a significant portion of our operations through our subsidiaries. We may therefore be dependent upon dividends or other intercompany transfers of funds from our subsidiaries in order to meet our obligations under the notes and to meet our other obligations. However, our subsidiaries are separate legal entities that have no obligation to pay any amounts due under the notes or to make any funds available therefor, whether by dividends, loans or other payments. Generally, creditors of our subsidiaries will have claims to the assets and earnings of our subsidiaries that are superior to the claims of our creditors, except to the extent the claims of our creditors are guaranteed by our subsidiaries. As of June 30, 2018, our subsidiaries accounted for approximately $5.0 billion, or 57%, of our total consolidated assets including assets held for sale but excluding intercompany balances, and had approximately $1.9 billion of outstanding liabilities, including trade payables and liabilities held for sale but excluding intercompany liabilities.

In the event of the bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding up of Motorola Solutions, the holders of the notes will not receive any amounts with respect to the notes until after the payment in full of the claims of creditors of our subsidiaries.

S-9

We are permitted to incur more debt, which may intensify the risks associated with our current leverage, including the risk that we will be unable to service our debt.

The indenture governing the notes does not limit the amount of additional debt that we may incur. If we incur additional debt, the risks associated with our leverage, including the risk that we will be unable to service our debt, will increase.

The provisions in the indenture that govern the notes relating to change of control transactions will not necessarily protect you in the event of a highly leveraged transaction.

The provisions contained in the indenture will not necessarily afford you protection in the event of a highly leveraged transaction that may adversely affect you, including a reorganization, restructuring, merger or other similar transaction involving us. These transactions may not involve a change in voting power or beneficial ownership or, even if they do, may not involve a change of the magnitude required under the definition of change of control repurchase event to trigger these provisions, notably, that the transactions are accompanied or followed within 90 days by a downgrade in the rating of the notes offered under this prospectus supplement. Except as described under “Description of the Notes—Purchase of Notes upon a Change of Control Repurchase Event,” the indenture does not contain provisions that permit the holders of the notes to require us to repurchase the notes in the event of a takeover, recapitalization or similar transaction.

We may not be able to repurchase all of the notes upon a change of control repurchase event.

As described under “Description of the Notes—Purchase of Notes upon a Change of Control Repurchase Event,” we will be required to offer to repurchase the notes upon the occurrence of a change of control repurchase event. We may not have sufficient funds to repurchase the notes in cash at such time or have the ability to arrange necessary financing on acceptable terms. In addition, our ability to repurchase the notes for cash may be limited by law or the terms of other agreements relating to our indebtedness outstanding at the time.

Negative covenants in the indenture will have a limited effect.

The indenture governing the notes contains negative covenants that apply to us and our domestic subsidiaries. These covenants are, however, subject to a number of significant exceptions that will permit us, in various circumstances, to create liens on our assets and to enter into sale and leaseback transactions. See “Description of the Notes—Restrictive Covenants” in this prospectus supplement. Holders of the notes may become structurally or contractually subordinated to new lenders who enter into transactions with us or our domestic subsidiaries in reliance on these exceptions.

There is no prior market for the notes. If one develops, it may not be liquid.

The notes are not listed and we do not intend to list the notes on any national securities exchange or to seek their quotation on any automated dealer quotation system. We cannot assure you that any liquid market for the notes will ever develop or be maintained. Further, there can be no assurance as to the liquidity of any market that may develop for the notes, your ability to sell your notes or the price at which you will be able to sell your notes. Future trading prices of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then-current ratings assigned to the notes and the market for similar securities. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including:

S-10

The underwriters have advised us that they currently intend to make a market in the notes following the offering. However, the underwriters have no obligation to make a market in the notes and they may stop at any time without notice.

Ratings of the notes may change after issuance and affect the market price and marketability of the notes.

We currently expect that, prior to issuance, the notes will be rated by Moody’s Investors Service Inc., Standard & Poor’s and Fitch Ratings Inc. Such ratings are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. Such credit ratings may not be issued or remain in effect for any given period of time or such ratings may be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. It is also possible that such ratings may be lowered in connection with future events, such as future acquisitions. Any lowering, suspension or withdrawal of such ratings, or the announcement that such ratings are under review for a possible downgrade may have an adverse effect on the market price or marketability of the notes.

S-11

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $194.2 million (after deducting underwriting discounts and commissions and estimated offering expenses payable by us, but not including accrued interest on the notes paid by the purchasers). We intend to use the net proceeds from the sale of the notes to fund a portion of the repurchase price of $200.0 million principal amount outstanding of our 2.0% senior convertible notes due 2020. On September 5, 2018, we agreed with a holder of our convertible notes to purchase from it $200 million in principal amount of convertible notes for aggregate consideration of $368.8 million in cash, inclusive of conversion premium. Settlement of the repurchase is expected to occur on or before October 17, 2018. We expect to fund the remaining cash consideration of the repurchase with available cash on our balance sheet. Pending such repurchase, we will temporarily invest the net proceeds from this offering in short-term, interest-bearing obligations.

S-12

CAPITALIZATION

The following table sets forth our consolidated short-term debt and capitalization as of June 30, 2018:

From time to time, we may issue additional debt or equity securities. This table should be read in conjunction with “Summary Consolidated Financial Data” appearing elsewhere in this prospectus supplement and our consolidated financial statements, including the notes thereto, which are incorporated herein by reference.

S-13

DESCRIPTION OF THE NOTES

We will issue the notes under an indenture dated August 19, 2014 between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “trustee”), or any successor trustee (the “indenture”). You should read the accompanying prospectus for a discussion of the terms and provisions of the indenture.

The following summary supplements, and to the extent it is inconsistent therewith replaces, the description of the general terms of the debt securities under the caption “Description of Debt Securities” in the accompanying prospectus. References in this section to “Motorola Solutions,” “us,” “our” and “we” are, unless the context otherwise requires, only to Motorola Solutions, Inc. and not to any of its subsidiaries.

The following summary of provisions of the indenture and the notes does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture, including definitions therein of certain terms and provisions made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). This summary may not contain all the information that you may find useful. You should read the indenture, a copy of which is available from Motorola Solutions upon request. The indenture is an exhibit incorporated by reference into the registration statement of which the prospectus attached to this prospectus supplement is a part.

General

The notes will form a single series with the $500,000,000 aggregate principal amount of 4.600% Senior Notes due 2028 that we issued on February 23, 2018. Accordingly, the notes offered by this prospectus supplement will have terms that are identical to the terms of the existing notes (other than the initial offering price and the initial interest payment date) and have the same CUSIP number and will be fungible with the existing notes. Upon the issuance of the notes offered hereby, the outstanding principal amount of our 4.600% Senior Notes due 2028 will be $700,000,000.

The notes will have the following basic terms:

S-14

Interest on each note will be paid to the person in whose name that note is registered at the close of business on February 10 or August 10, as the case may be, immediately preceding the relevant interest payment date. Interest on the notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

If any interest or other payment date of a note falls on a day that is not a business day, the required payment of principal, premium, if any, or interest will be made on the next succeeding business day as if made on the date that the payment was due, and no interest will accrue on that payment for the period from and after that interest or other payment date, as the case may be, to the date of that payment on the next succeeding business day. The term “business day” means, with respect to any note, any day other than a Saturday, a Sunday or a day on which banking institutions or trust companies in New York City are authorized or required by law, regulation or executive order to close.

The notes will not be subject to any sinking fund.

Motorola Solutions may, subject to compliance with applicable law, at any time purchase notes in the open market or otherwise.

Ranking

The notes will be senior unsecured obligations of Motorola Solutions and will rank equally in right of payment with all existing and future unsecured and unsubordinated obligations of Motorola Solutions. As of June 30, 2018, Motorola Solutions had approximately $5.641 billion of senior unsecured indebtedness outstanding.

The notes will effectively rank junior in right of payment to all existing and future secured indebtedness of Motorola Solutions to the extent of the assets securing such indebtedness, and to all existing and future liabilities of its subsidiaries, including indebtedness and trade payables. As of June 30, 2018, Motorola Solutions had approximately $4.0 million of secured indebtedness outstanding arising from a consolidated joint venture investment. Motorola Solutions derives a significant portion of its operating income and cash flow from its subsidiaries. Therefore, Motorola Solutions’ ability to make payments when due to the holders of the notes is, in large part, dependent upon the receipt of sufficient funds from its subsidiaries.

Claims of creditors of Motorola Solutions’ subsidiaries generally will have priority with respect to the assets and earnings of such subsidiaries over the claims of Motorola Solutions’ creditors, including holders of the notes. Accordingly, the notes will be effectively subordinated to creditors, including trade creditors and preferred stockholders, if any, of Motorola Solutions’ subsidiaries. As of June 30, 2018, Motorola Solutions’ subsidiaries had approximately $1.9 billion of outstanding liabilities, including trade payables and liabilities held for sale but excluding intercompany liabilities.

Optional Redemption

Motorola Solutions may redeem the notes at its option, either in whole or in part, at any time prior to November 23, 2027 (three months prior to the stated maturity of the notes) (the “par call date”), at a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date:

S-15

In determining the present values of the Remaining Scheduled Payments, Motorola Solutions will discount such payments to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the sum of the applicable Treasury Rate, plus 25 basis points.

On or after November 23, 2027 (three months prior to the stated maturity of the notes), Motorola Solutions may redeem the notes at its option, either in whole or in part, at a redemption price equal to 100%, plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date.

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

“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 of the notes 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 the notes called for redemption.

“Comparable Treasury Price” means, with respect to any redemption date, (1) the arithmetic average of the Reference Treasury Dealer Quotations for such redemption date, or (2) if only one Reference Treasury Dealer Quotation is obtained, 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 Motorola Solutions; provided, however, that if the foregoing ceases to be a primary U.S. Government securities dealer in New York City (a “primary treasury dealer”), Motorola Solutions will substitute another nationally recognized investment banking firm that is a primary treasury dealer.

“Reference Treasury Dealer” means Deutsche Bank Securities Inc. and J.P. Morgan Securities LLC, and each of their respective successors. If any of the foregoing ceases to be a primary treasury dealer, Motorola Solutions will substitute another nationally recognized investment banking firm that is a primary treasury dealer.

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

“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 (assuming the note matures on the par call date); 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 semiannual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the Comparable Treasury Issue. In determining this rate, Motorola Solutions will assume 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.

A partial redemption of the notes will be effected in accordance with applicable DTC procedures.

S-16

Notice of any redemption will be delivered at least 15 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. Once notice of redemption is delivered, the notes called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date.

Unless Motorola Solutions defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes, or portions thereof, called for redemption. Prior to 11:00 a.m. on the redemption date, Motorola Solutions will deposit with a paying agent (or the trustee) money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on that date.

Purchase of Notes upon a Change of Control Repurchase Event

If a change of control repurchase event occurs, unless Motorola Solutions has exercised its right to redeem the notes as described above, Motorola Solutions will be required to make an offer to each holder of the notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of that holder’s notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the notes repurchased plus any accrued and unpaid interest on the notes repurchased to, but not including, the date of repurchase. Within 30 days following any change of control repurchase event or, at the option of Motorola Solutions, prior to any change of control, but after the public announcement of the change of control, Motorola Solutions will mail a notice to each holder, with a copy to the trustee, describing the transaction or transactions that constitute or may constitute the change of control repurchase event and offering to repurchase the 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 delivered. The notice shall, if delivered prior to the date of consummation of the change of control, state that the offer to purchase is conditioned on a change of control repurchase event occurring on or prior to the payment date specified in the notice.

Motorola Solutions 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 repurchase event. To the extent that the provisions of any securities laws or regulations conflict with the change of control repurchase event provisions of the notes, Motorola Solutions will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the change of control repurchase event provisions of the notes by virtue of compliance with such securities laws or regulations.

On the repurchase date following a change of control repurchase event, Motorola Solutions will, to the extent lawful:

(1) accept for payment all the notes or portions of the notes properly tendered pursuant to its offer;

(2) deposit with the paying agent an amount equal to the aggregate purchase price in respect of all the notes or portions of the notes properly tendered; and

(3) deliver or cause to be delivered to the trustee the notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of notes being purchased by Motorola Solutions.

The paying agent will promptly mail or otherwise deliver to each holder of notes 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 holder a new note equal in principal amount to any unpurchased portion of any notes surrendered.

Motorola Solutions will not be required to make an offer to repurchase the notes upon a change of control repurchase event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by Motorola Solutions and such third party purchases all notes properly tendered and not withdrawn under its offer.

S-17

The change of control repurchase event feature of the notes may in certain circumstances make more difficult or discourage a sale or takeover of Motorola Solutions and, thus, the removal of incumbent management. The change of control repurchase event feature is a result of negotiations between Motorola Solutions and the underwriters. Motorola Solutions has no present intention to engage in a transaction involving a change of control, although it is possible that Motorola Solutions could decide to do so in the future. Subject to the limitations discussed below, Motorola Solutions could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a change of control under the indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect the capital structure of Motorola Solutions or credit ratings of the notes. Restrictions on the ability of Motorola Solutions to incur liens and enter into sale and leaseback transactions are contained in the covenants as described in the accompanying prospectus. Except for the limitations contained in such covenants and the covenant relating to repurchases upon the occurrence of a change of control repurchase event, however, the indenture will not contain any covenants or provisions that may afford holders of the notes protection in the event of a decline in the credit quality of Motorola Solutions or a highly leveraged or similar transaction involving Motorola Solutions.

Motorola Solutions may not have sufficient funds to repurchase all the notes upon a change of control repurchase event. In addition, even if it has sufficient funds, Motorola Solutions may be prohibited from repurchasing the notes under the terms of its future debt instruments. See “Risk Factors—Risks Related to the Notes—We may not be able to repurchase all of the notes upon a change of control repurchase event.”

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

“change of control” means the occurrence of any of the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of Motorola Solutions and its subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d) and Section 14(d) of the Exchange Act) other than Motorola Solutions or one of its subsidiaries; (2) the adoption of a plan relating to Motorola Solutions’ liquidation or dissolution; (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above) becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of Motorola Solutions’ stock or other voting stock into which Motorola Solutions’ voting stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; or (4) the first day on which a majority of the members of the board of directors of Motorola Solutions are not continuing directors.

“change of control repurchase event” means the occurrence of both a change of control and a ratings event.

“continuing directors” means, as of any date of determination, any member of the board of directors of Motorola Solutions who (1) was a member of such board of directors on the date of the issuance of the notes; or (2) was nominated for election or elected to such board of directors with the approval of a majority of the continuing directors who were members of such board of directors at the time of such nomination or election.

“investment grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by Motorola Solutions.

“Moody’s” means Moody’s Investors Service Inc. and its successors.

“rating agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the control of Motorola Solutions, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act, selected by Motorola Solutions (as certified by a resolution of the board of directors of Motorola Solutions) as a replacement agency for Moody’s or S&P, or both, as the case may be.

“rating category” means (i) with respect to S&P, any of the following categories: BBB, BB, B, CCC, CC, C and D (or equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of S&P or Moody’s used by another rating agency. In determining whether the rating of the notes has decreased by one or more gradations, gradations within rating categories (+ and—for S&P; 1, 2 and 3 for Moody’s; or the equivalent gradations for another rating agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB- to B+, will constitute a decrease of one gradation).

“rating date” means the date which is 90 days prior to the earlier of (i) a change of control or (ii) public notice of the occurrence of a change of control or of the intention by Motorola Solutions to effect a change of control.

“ratings event” means the occurrence of the events described in (a) or (b) below on, or within 60 days after 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 Motorola Solutions to effect a change of control (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): (a) in the event the notes are rated by both rating agencies on the rating date as investment grade, the rating of the notes shall be reduced so that the notes are rated below investment grade by both rating agencies, or (b) in the event the notes (1) are rated investment grade by one rating agency and below investment grade by the other rating agency, the rating of the notes by either rating agency shall be decreased by one or more gradations (including gradations within rating categories, as well as between rating categories) so that the notes are then rated below investment grade by both rating agencies or (2) are rated below investment grade by both rating agencies on the rating date, the rating of the notes by either rating agency shall be decreased by one or more gradations (including gradations within rating categories, as well as between rating categories) or is withdrawn. Notwithstanding the foregoing, a ratings event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular change of control (and thus shall not be deemed a ratings event for purposes of the definition of change of control repurchase event hereunder) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable change of control (whether or not the applicable change of control shall have occurred at the time of the ratings event).

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

“voting stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

Restrictive Covenants

Restrictions on Secured Debt

If we or any Domestic Subsidiary incurs or guarantees any Debt secured by a Mortgage on any Principal Property or on any shares of stock or Debt of any Domestic Subsidiary, we must secure the notes, and each other

S-19

series of debt securities issued under the indenture, equally and ratably with (or prior to) such secured Debt, unless, after giving effect to such transaction, the aggregate amount of all such Debt so secured, together with all Attributable Debt in respect of sale and leaseback transactions involving Principal Properties, would not exceed 15% of the Consolidated Net Tangible Assets of us and our consolidated subsidiaries. See “—Restrictive Covenants—Restrictions on Sales and Leasebacks” below.

This restriction does not apply to, and there will be excluded from secured Debt in any computation under such restriction, Debt secured by:

Restrictions on Sales and Leasebacks

Neither we nor any Domestic Subsidiary may enter into any sale and leaseback transaction involving any Principal Property, completion of construction and commencement of full operation of which has occurred more than 180 days prior thereto, unless:

This restriction will not apply to any sale and leaseback transaction:

Certain Definitions

The following are certain key definitions used in the descriptions above of restrictions on secured debt and sales and leasebacks contained in the indenture. These and other definitions are contained in the indenture. You should read the indenture to understand these restrictions fully.

“Attributable Debt” means the total net amount of rent required to be paid during the remaining term of any lease, discounted at the rate per annum borne by the senior debt securities of each series, compounded annually.

S-20

“Consolidated Net Tangible Assets” means the aggregate amount of assets, less applicable reserves and other properly deductible items, after deducting from that net amount:

“Domestic Subsidiary” means a Subsidiary of ours except a Subsidiary of ours which neither transacts any substantial portion of its business nor regularly maintains any substantial portion of its fixed assets within the United States, or which is engaged primarily in financing our operations or our Subsidiaries, or both, outside the United States.

“Funded Debt” means all indebtedness for money borrowed having a maturity of more than 12 months from the date of the most recent balance sheet of us and our consolidated subsidiaries or having a maturity of less than 12 months but by its terms being renewable or extendible beyond 12 months from the date of such balance sheet at the option of the borrower.

“Principal Property” includes any single parcel of real estate, any manufacturing plant or warehouse we own or lease or any Domestic Subsidiary owns or leases which is located within the United States and the gross book value, without deduction of any depreciation reserves, of which on the date as of which the determination is being made exceeds 1% of Consolidated Net Tangible Assets, other than any single parcel of real estate or manufacturing plant or warehouse or a portion of any manufacturing plant or warehouse:

“Subsidiary” shall mean any corporation, association, partnership or other business entity of which more than 50% of the total voting stock or other interests (including partnership interests) entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof is at the time owned or controlled, directly or indirectly, by the Company or by one or more other Subsidiaries, or by the Company and one or more other Subsidiaries.

Defeasance and Covenant Defeasance

Under the indenture, we have the ability to take certain steps to effect a “defeasance” or a “covenant defeasance.” A defeasance allows us to be discharged from any and all obligations in respect of a series of debt securities issued under the indenture except for certain obligations to register the transfer or exchange of such debt securities, to replace temporary, destroyed, stolen, lost or mutilated debt securities, to maintain paying agencies and to hold monies for payment in trust. A covenant defeasance allows us to stop complying with certain restrictive covenants relating to:

A covenant defeasance also causes certain events specified in the indenture to no longer be deemed an event of default under the indenture.

S-21

To effect a defeasance or a covenant defeasance, we must deposit with the applicable trustee an amount of money or U.S. government securities that, through the payment of interest and principal in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of, and premium, if any, and each installment of interest, if any, on the debt securities of such series at the time such payments are due. We will remain liable for any shortfall between the amount deposited with the trustee and the amount due holders of debt securities upon any acceleration of payment.

We may only effect a defeasance or a covenant defeasance if we have provided a legal opinion that such action will not cause holders of our debt securities to recognize income, gain or loss for federal income tax purposes as a result and that holders will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. The opinion, in the case of a defeasance, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable Federal income tax law occurring after the date of the indenture.

Events of Default

The following are events of default under the indenture with respect to any debt securities issued thereunder:

If an event of default with respect to the outstanding debt securities of any series occurs and continues either the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all debt securities of that series to be due and payable immediately; provided that in the case of certain events of bankruptcy, insolvency or reorganization, such principal amount, or portion thereof, will automatically become due and payable. However, at any time after an acceleration with respect to debt securities of any series has occurred, but before a judgment or decree based on such acceleration has been obtained, the holders of a majority in principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration (section 502 of the indenture). For information as to waiver of defaults, see “—Modification and Waiver” below.

Subject to the duty of the trustee during default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless such holders have offered the trustee reasonable security or indemnity (section 603 of the indenture). Subject to such indemnification and certain other limitations, the holders of a majority in principal amount of the outstanding debt securities of any series 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 debt securities of that series (section 512 of the indenture).

We will be required to furnish to the trustee an annual statement as to our performance of certain of our obligations under the indenture and as to any default in such performance (section 1006 of the indenture).

S-22

Modification and Waiver

Modifications and amendments of the indenture may be made by us and the trustee with the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected thereby, except that no such modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby:

The holders of a majority of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive, insofar as that series is concerned, our compliance with certain restrictive provisions of the indenture (section 1008 of the indenture). The holders of a majority of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive any past default under the indenture with respect to debt securities of that series, except a default in the payment of the principal of, or premium, if any, or interest, if any, on any debt security of that series or in respect of any provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of that series affected (section 513 of the indenture).

Consolidation, Merger, Conveyance, Transfer or Lease

We may, without the consent of any holders of outstanding debt securities, consolidate or merge with or into, or transfer or lease our assets substantially as an entirety to, any entity, and any other entity may consolidate or merge with or into, or transfer or lease its assets substantially as an entirety to, us, provided that:

Form, Denominations, Exchange, Registration and Transfer

We will issue debt securities issued under the indenture as registered securities, which may be issued in global form. Global securities are described below under “—Book-entry; Delivery and Form; Global Notes.” We will issue registered securities issued under the indenture in denominations of $2,000 and integral multiples of $1,000.

S-23

Our registered securities issued under the indenture will be exchangeable for other registered securities of the same series.

You may present the registered securities for registration of transfer at the office of the trustee, or at the office of any transfer agent we designate without service charge and upon payment of any taxes and other governmental charges (section 305 of the indenture). We may change transfer agents or designate additional transfer agents at any time, except that, we must maintain a transfer agent in each place of payment for such series (section 1002 of the indenture).

If we elect or are required to redeem or exchange particular debt securities, we will not be required to:

Payment and Paying Agents

The place of payment for all debt securities issued under the indenture will be New York, New York, U.S.A., and we will initially designate the corporate trust office of the trustee for this purpose. At our option, we may pay interest, if any, on registered securities by check mailed to the address of the person entitled thereto as such person’s address appears in the security register or by wire transfer to an account located in the United States maintained by the person entitled thereto as specified in the security register (sections 307, 1001 and 1002 of the indenture). We will make payment of any installment of interest on registered securities to the person in whose name such registered security is registered at the close of business on the record date for such interest (section 307 of the indenture).

We will make all payments of principal of, and premium, if any, and interest, if any, on any debt security that is payable in a currency other than U.S. dollars in U.S. dollars if such currency:

We may designate additional offices or agencies for payment with respect to any debt securities, approve a change in the location of any such office or agency and, except as provided above, rescind the designation of any such office or agency.

Governing Law

The indenture is and the debt securities issued thereunder will be governed by, and construed in accordance with, the laws of the State of New York.

Book-entry; Delivery and Form; Global Notes

The notes will be represented by one or more global notes in definitive, fully registered form without interest coupons. Each global note will be deposited with the trustee as custodian for DTC and registered in the name of a nominee of DTC in New York, New York for the accounts of participants in DTC.

S-24

Investors may hold their interests in a global note directly through DTC if they are DTC participants, or indirectly through organizations that are DTC participants. Holders of notes represented by interests in a global note will not be entitled to receive their notes in fully registered certificated form.

DTC has advised as follows: DTC is a limited-purpose trust company organized under New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities of institutions that have accounts with DTC (“participants”) and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers (which may include the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s book-entry system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, whether directly or indirectly.

Further Issuances

Motorola Solutions may from time to time, without notice to or the consent of the holders of the notes, create and issue additional notes having the same terms as, and ranking equally and ratably with, the notes in all respects (except for the issue date and, if applicable, the payment of interest accruing prior to the issue date of such additional notes and the first payment of interest following the issue date of such additional notes). Such additional notes may be consolidated and form a single series with, and will have the same terms as to ranking, redemption, waivers, amendments or otherwise, as the notes, and will vote together as one class on all matters with respect to the notes, unless such additional notes are not treated as fungible for U.S. tax purposes with the notes issued pursuant to this offering.

All senior debt securities issued under the indenture are unsubordinated obligations of the company. They will be unsecured and will rank equally with each other and all of our other unsubordinated debt (section 301 of the indenture). The indenture does not limit the aggregate principal amount of debt securities that we may issue thereunder and provides that we may issue debt securities thereunder from time to time in one or more series.

Effective Subordination

The debt securities issued under the indenture will be our obligations exclusively. Since our operations are partially conducted through subsidiaries, primarily overseas, our cash flow and therefore our ability to service debt, including the debt securities offered by this prospectus supplement, are partially dependent upon the earnings of our subsidiaries and the distribution of those earnings to, or upon loans or other payments of funds by those subsidiaries to, us. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due pursuant to the debt securities or to make any funds available to us to repay our obligations, whether by dividends, loans or other payments. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to statutory or contractual restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations.

Any right of ours to receive assets of any of our subsidiaries upon their liquidation or reorganization and therefore the right of the holders of the debt securities to participate in those assets will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors.

No Limitations on Other Debt

The general provisions of the indenture do not contain any provisions that would limit our ability to incur indebtedness or that would afford holders of debt securities protection in the event of a highly leveraged or

S-25

similar transaction involving us. However, the indenture does restrict us and our domestic subsidiaries from granting certain security interests on certain of their property or assets unless the debt securities are equally secured. See “—Restrictive Covenants” above.

Regarding the Trustee

The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture and has also been appointed by Motorola Solutions to act as registrar, transfer agent and paying agent for the notes. The Bank of New York Mellon Trust Company, N.A. is also trustee under:

The indentures governing the aforementioned notes contain provisions limiting the liability of the trustee in certain circumstances. Under the indentures, force majeure events may in certain cases specified in the indentures relieve the trustee from liability.

We maintain various banking relationships with The Bank of New York Mellon, an affiliate of the trustee. The Bank of New York Mellon serves as custodian and record keeper for Motorola Solutions’ fund used to invest most of its U.S. dollar denominated cash and provides investment management services to us.

S-26

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain U.S. federal income tax consequences of the ownership and disposition of the notes.

This discussion does not address all aspects of U.S. federal income taxation that may be relevant to particular holders in light of their special circumstances or holders subject to special treatment under U.S. federal income tax laws (including brokers or dealers in securities or currencies, banks, thrifts or other financial institutions or financial service companies, cooperatives, regulated investment companies, real estate investment trusts, tax-exempt organizations, pension funds, insurance companies, government instrumentalities or agencies, traders or dealers in securities, persons who hold notes as part of a hedging, straddle, conversion or constructive sale transaction, persons subject to the alternative minimum tax, U.S. Holders (as defined below) whose functional currency is not the U.S. dollar, U.S. expatriates, non-U.S. trusts that have U.S. beneficiaries, retirement plans, individual retirement accounts or other tax deferred accounts, controlled foreign corporations, passive foreign investment companies, persons required for U.S. federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451(b) of the Internal Revenue Code of 1986, as amended (the “Code”), partnerships and other flow-through entities (including entities or other arrangements treated as partnerships or flow-through entities for U.S. federal income tax purposes)). This discussion does not address any aspect of U.S. federal taxation other than U.S. federal income taxation (such as estate and gift tax laws) or any aspect of state, local or non-U.S. taxation. In addition, this discussion deals only with certain U.S. federal income tax consequences to a holder that acquires the notes in the initial offering at their “issue price” (the first price at which a substantial amount of the notes is sold for money to investors, not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and holds the notes as capital assets.

This summary is based on the Code, U.S. Treasury regulations issued thereunder, Internal Revenue Service (“IRS”) rulings and pronouncements and judicial decisions in effect as of the date of this offering supplement, which is subject to differing interpretations and could change, possibly with retroactive effect. We have not sought a ruling from the IRS with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions. We urge you to consult with your tax advisor about the U.S. federal income tax and other tax consequences of an investment in the notes.

If any entity treated as a partnership for U.S. federal income tax purposes holds a note, the U.S. federal income tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding a note should consult its tax advisor concerning the U.S. federal income and other tax consequences of an investment in the notes.

EACH PROSPECTIVE HOLDER OF THE NOTES SHOULD CONSULT ITS TAX ADVISOR CONCERNING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE OWNERSHIP OR DISPOSITION OF THE NOTES BASED UPON THEIR PARTICULAR CIRCUMSTANCES.

Effect of Certain Additional Payments

In certain circumstances, we may be obligated to pay amounts in excess of stated interest or principal on the notes. For example, upon the occurrence of a “change of control repurchase event,” (as defined under “Description of the Notes—Purchase of Notes upon a Change of Control Repurchase Event,”) we will be required to offer to repurchase some or all of the notes at 101% of their principal amount, plus accrued and unpaid interest. The obligation to make such payments may implicate the provisions of Treasury regulations relating to “contingent payment debt instruments” (“CPDI”). One or more contingencies will not cause the notes to be treated as a CPDI if, as of the issue date, each such contingency is considered remote or incidental or, in

S-27

certain circumstances, it is significantly more likely than not that such contingency will not occur. We believe and intend to take the position that the potential for additional payments on the notes should not cause the notes to be treated as CPDIs. Our determination is binding on a holder unless such holder discloses its contrary position in the manner required by the applicable Treasury regulations. Our determination is not, however, binding on the IRS. If the IRS takes a contrary position and such position is sustained, note holders could be required to accrue ordinary interest income on the notes at a rate in excess of the stated interest rate and to treat all or a portion of any gain recognized on a sale or other taxable disposition of a note as ordinary income rather than capital gain. In the event a contingent payment is actually made, such payment could affect the amount and timing of payments that such a holder would recognize for U.S. federal income tax purposes. Prospective holders of the notes should consult their tax advisors regarding the possible application of the CPDI rules on the notes and the consequences thereof. The remainder of this discussion assumes that the notes will not be treated as CPDIs for U.S. federal income tax purposes.

U.S. Holders

As used in this discussion, a “U.S. Holder” is a beneficial owner of a note that is, for U.S. federal income tax purposes:

Pre-Acquisition Accrued Interest

A portion of the price paid for the notes issued pursuant to this offering will be allocable to interest that accrued prior to the date such notes are purchased (“pre-acquisition accrued interest”). To the extent that a portion of a U.S. Holder’s purchase price for the notes is allocable to pre-acquisition accrued interest, a portion of the first stated interest payment equal to the amount of such pre- acquisition accrued interest may be treated as a nontaxable return of such pre-acquisition accrued interest to the U.S. Holder and not as a payment of interest on the note. The remainder of this discussion assumes that the notes will be so treated, and all references to interest in the remainder of this discussion exclude references to pre-acquisition accrued interest.

Stated Interest

All of the notes bear interest at a stated fixed rate. A U.S. Holder generally must include this stated interest in its gross income as ordinary interest income:

Sale or Other Taxable Disposition of a Note

A U.S. Holder will generally recognize capital gain or loss upon the sale, exchange, retirement, redemption or other taxable disposition of a note in an amount equal to the difference between (i) the amount realized (except to

S-28

the extent such amount is attributable to accrued but unpaid stated interest, which will be taxable as ordinary interest income to the extent such interest has not been previously included in income) and (ii) such U.S. Holder’s adjusted tax basis in the note. The amount realized will be equal to the sum of the amount of cash and the fair market value of any property received in exchange for the note. A U.S. Holder’s adjusted tax basis in a note will generally equal the cost of the note to such holder, decreased by any payment on the notes, other than a payment of qualified stated interest. Such capital gain or loss will be long-term capital gain or loss if the note was held for more than one year at the time of disposition. In general, for non-corporate taxpayers, long-term capital gains are currently taxed at a maximum rate of 20%. The deductibility of capital losses is subject to significant limitations. U.S. Holders should consult their tax advisor regarding the treatment of capital gains and losses.

Qualified Reopening

Debt instruments issued as part of the “qualified reopening” of a previous issue of debt instruments are treated as part of the original issue and, consequently, are deemed to have the same issue date and the same issue price as the original debt instruments. It is expected that this offering of the notes will meet the requirements for a “qualified reopening” of the notes issued on February 23, 2018 under applicable U.S. Treasury regulations. Accordingly, we expect that, and this discussion assumes that for U.S. federal income tax purposes, the notes will have the same issue price and issue date as the notes issued on February 23, 2018 and will not be considered to be issued with “original issue discount” for U.S. federal income tax purposes.

Note Premium

If a note is issued for an amount in excess of its principal amount, the holder may elect to treat the excess as amortizable note premium. By making this election, the holder will reduce the amount required to be included in the holder’s income each year with respect to interest on the note by the amount of amortizable note premium allocable to that year, based on the yield to maturity of the note. If the holder makes an election to amortize note premium, it will apply to all debt instruments, other than debt instruments the interest on which is excludible from gross income, that the holder holds at the beginning of the first taxable year to which the election applies or that the holder thereafter acquires, and the holder may not revoke it without the consent of the IRS.

Net Investment Income Tax

A U.S. Holder that is an individual, trust, or estate is subject to a surtax of 3.8% on the lesser of (1) such U.S. Holder’s “net investment income” (or undistributed “net investment income” in the case of estates or trusts) for the relevant taxable year and (2) the excess of such U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). Among other items, “net investment income” generally includes gross income from interest and net gain attributable to the disposition of certain property, less certain deductions. Prospective investors should consult their tax advisors concerning the possible implications of this net investment income tax in their particular circumstances.

Backup Withholding and Information Reporting

Payments of interest and principal on a note and the proceeds of the sale or other taxable disposition of a note are generally subject to information reporting unless the U.S. Holder is an exempt recipient. Such payments may also be subject to U.S. federal backup withholding tax (currently at a rate of 24%) if the recipient of such payment fails to timely supply a U.S. taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise fails to timely establish an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against that U.S. Holder’s U.S. federal income tax liability (if any) provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding the application of backup withholding based upon their particular situation, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if available.

S-29

Non-U.S. Holders

As used in this discussion, a “Non-U.S. Holder” is a beneficial owner of a note that is (i) for U.S. federal income tax purposes, an individual, corporation, estate or trust (other than a grantor trust), and (ii) not a U.S. Holder.

Interest

Subject to the discussions below concerning backup withholding and FATCA (as defined below) withholding, no U.S. federal income or withholding tax generally will apply to a payment of interest on a note to a Non-U.S. Holder, provided that:

If any of the foregoing requirements are not met, payments of interest on a note generally will be subject to U.S. federal withholding tax at a 30% rate (or a lower applicable treaty rate, provided certain certification requirements are met), subject to the discussion below concerning interest that is effectively connected with a Non-U.S. Holder’s conduct of a trade or business in the United States.

Prospective Non-U.S. Holders should consult their tax advisors regarding these certification requirements and any alternative methods for satisfying the certification requirements described above.

Sale or Other Taxable Disposition of a Note

Subject to the discussions of backup withholding and FATCA below, a Non-U.S. Holder generally will not be subject to U.S. federal income tax on the receipt of payments of principal on a note, or on any gain recognized upon the sale, exchange, retirement, redemption or other taxable disposition of a note, unless in the case of gain (i) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business within the United States and, if a treaty applies (and the holder complies with applicable certification and other requirements to claim treaty benefits), such gain is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder within the United States or (ii) such Non-U.S. Holder is 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 addition, subject to the discussion below concerning backup withholding and the discussion concerning FATCA withholding, a Non-U.S. Holder generally will not be subject to U.S. federal withholding tax on the receipt of payments of principal on a note, or on any gain recognized upon the sale, exchange, retirement, redemption or other taxable disposition of a note.

United States Trade or Business

If a Non-U.S. Holder is engaged in a trade or business in the United States, and if interest or gain on a note is effectively connected with the conduct of such trade or business and, if a treaty applies (and the holder complies

S-30

with applicable certification and other requirements to claim treaty benefits), such interest or gain is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder within the United States, the Non-U.S. Holder generally will be subject to U.S. federal income tax on the receipt or accrual of such interest or the recognition of gain on the sale or other taxable disposition of the note in the same manner as if such holder were a United States person (within the meaning of the Code). A corporate Non-U.S. Holder may also be subject to an additional U.S. federal branch profits tax at a 30% rate (or, if applicable, a lower treaty rate) on its effectively connected earnings and profits attributable to such interest or gain. In addition, any interest or gain that is effectively connected with a Non-U.S. Holder’s conduct of a trade or business in the United States will not be subject to withholding tax (subject to the discussion of FATCA below). A Non-U.S. Holder may establish that interest or gain is effectively connected with a trade or business in the United States by timely delivering a properly executed IRS Form W-8ECI.

Backup Withholding and Information Reporting

A Non-U.S. Holder may be required to comply with certain certification procedures to establish that the holder is not a United States person (within the meaning of the Code) in order to avoid information reporting and backup withholding tax with respect to our payment of principal and interest on, or the proceeds of, the sale or other taxable disposition of a note. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a credit against a Non-U.S. Holder’s United States federal income tax liability, if any, and may entitle such Non-U.S. Holder to a refund, provided the required information is timely furnished to the IRS.

In addition, we are required to annually report to the IRS and each Non-U.S. Holder the amount of any interest paid to such Non-U.S. Holder, regardless of whether any tax was actually withheld, other than with respect to certain exempt recipients, including corporations. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides. Non-U.S. Holders should consult their tax advisors with respect to these withholding and reporting rules as well as other U.S. tax consequences of the ownership and disposition of notes.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code, Treasury regulations promulgated thereunder and official IRS guidance commonly referred to as the “Foreign Account Tax Compliance Act” (“FATCA”) will impose a 30% withholding tax on payments of interest in respect of, and gross proceeds from the sale of, the notes made to (a) foreign financial institutions (including investment funds and including in certain instances where such institutions are acting as intermediaries), unless they agree to collect and disclose to the IRS (or, if required under an intergovernmental agreement between the U.S. and an applicable foreign country, report such information to a local tax authority) information regarding their direct and indirect U.S. account holders; or (b) certain non-financial foreign entities unless such an entity either (i) certifies to us that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” generally by providing an IRS Form W-8BEN-E (which we will in turn provide to the IRS), unless certain exemptions apply. However, withholding will not apply to payments of gross proceeds from a sale or other disposition of notes before January 1, 2019. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury regulations or other official guidance, may modify these requirements. Amounts that a holder receives on the notes could be subject to FATCA withholding if a holder is subject to the information reporting requirements and fails to comply with them or if a holder holds notes through another person (e.g., a foreign bank or broker) that is subject to withholding because it fails to comply with these requirements (even if the holder would not otherwise have been subject to withholding).

Prospective holders of notes should consult their tax advisors regarding the relevant U.S. law and other official guidance regarding FATCA. Depending on a holder’s circumstances, a holder of notes may be entitled to a refund or credit in respect of some or all of any applicable FATCA withholding. However, even if a holder is entitled to have any such withholding refunded, the required procedures could be cumbersome and significantly delay the holder’s receipt of any withheld amounts.

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement dated the date of this prospectus supplement, we have agreed to sell to each of the underwriters named below (for whom Deutsche Bank Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives), and each of the underwriters has severally agreed to purchase, the respective principal amount of the notes set forth opposite its name below:

Under the terms and conditions of the underwriting agreement, if the underwriters take any of the notes, then the underwriters are obligated to take and pay for all of the notes.

The notes will be part of our 4.600% Senior Notes due 2028, of which we issued $500,000,000 in aggregate principal amount on February 23, 2018. The notes offered by this prospectus supplement will have terms that are identical to the terms of the existing notes (other than the initial offering price and the initial interest payment date) and have the same CUSIP number and will be fungible with the existing notes. Upon the issuance of the notes offered hereby, the outstanding principal amount of our 4.600% Senior Notes due 2028 will be $700,000,000.

The notes are not listed and we do not intend to list the notes on any national securities exchange or to seek their quotation on any automated dealer quotation system. The underwriters have advised us that they intend to make a market in the notes, but they have no obligation to do so and may discontinue market making at any time without providing notice. No assurances can be given as to the liquidity of any trading market for the notes.

The underwriters initially propose to offer part of the notes directly to the public at the offering prices described on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of 0.300% of the principal amount of the notes. Any underwriter may allow, and any such dealer may reallow, a concession to certain other dealers not in excess of 0.150% of the principal amount of the notes. After the initial offering of the notes, the underwriters may from time to time vary the offering price and other selling terms.

We have also agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

S-32

We have agreed, during the period from the date of the underwriting agreement until the business day immediately following the delivery of the notes, not to offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by us having a tenor of more than one year without the prior written consent of the representatives.

We expect that delivery of the Notes will be made to investors on or about October 5, 2018, which is the fifth business day following the date of this prospectus supplement (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the date of this prospectus or the following two business days will be required, by virtue of the fact that the Notes initially settle in T+5, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes on the date of this prospectus supplement or on the following two business days should consult their advisors.

In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the underwriters may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the price of the notes. Finally, the underwriters may impose a penalty bid. The underwriting syndicate may reclaim selling concessions allowed for distributing the notes in this offering, if the syndicate repurchases previously distributed notes in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time.

Expenses associated with this offering, to be paid by us, are estimated to be approximately $300,000.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for Motorola Solutions, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of Motorola Solutions (directly, as collateral securing other obligations or otherwise). Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, 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 our 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 make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Affiliates of each of the joint book-running managers are, and certain of the co-managers may be, lenders under a $2.2 billion Revolving Credit Agreement dated as of April 25, 2017 among Motorola Solutions, JPMorgan Chase Bank, N.A., as administrative agent, and the several lenders and agents party thereto.

Selling Restrictions

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

No advertisement, invitation or document relating to the notes, which is directed at, or the contents of which are likely to be accessed or read by, the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) has been or will be issued other than with respect to the notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” (as defined in the SFO) and any rules made thereunder.

Investing in our securities involves risks. You should carefully consider the risk factors described in Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017 and our other reports filed from time to time with the SEC, which are incorporated by reference into this prospectus, as the same may be amended, supplemented or superseded from time to time by our filings under the Exchange Act, as well as any prospectus supplement relating to a specific security. Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus or in any applicable prospectus supplement or free writing prospectus. For more information, see the section entitled “Where You Can Find More Information” below. These risks could materially affect our business, results of operations or financial condition and affect the value of our securities. You could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operations or financial condition.

USE OF PROCEEDS

Unless otherwise set forth in the applicable prospectus supplement, we intend to use the net proceeds of any offering of our securities for working capital and other general corporate purposes. We will have significant discretion in the use of any net proceeds. The net proceeds from the sale of securities may be invested temporarily until they are used for their stated purpose. We may provide additional information on the use of the net proceeds from the sale of our securities in an applicable prospectus supplement or other offering materials related to the offered securities.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the debt securities, common stock, debt securities warrants, common stock warrants, stock purchase contracts and stock purchase units that we may offer and sell from time to time. These summary descriptions are not meant to be complete descriptions of any security. At the time of an offering and sale, this prospectus, together with the accompanying prospectus supplement, will contain the material terms of the securities being offered.

DESCRIPTION OF DEBT SECURITIES

The following is a general description of the debt securities that we may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply will be described in the applicable prospectus supplement. We may also sell hybrid or novel securities now existing or developed in the future that combine certain features of debt securities and other securities described in this prospectus.

The debt securities will be either senior debt securities or subordinated debt securities. We will issue the “senior debt securities” under the “senior indenture” dated August 19, 2014 between us and The Bank of New York Mellon Trust Company, N.A., as trustee, or any successor trustee (as the same may be amended, supplemented, modified, restated or replaced). We will issue the “subordinated debt securities” under a “subordinated indenture” to be entered into later, between us and the trustee named therein, or any successor trustee. The senior indenture and the subordinated indenture are collectively referred to in this prospectus as the “indentures,” and each of the trustee under the senior indenture and the trustee under the subordinated indenture are referred to in this prospectus as a “trustee.” The senior indenture and a form of subordinated indenture are included as exhibits to this registration statement and the following description is qualified in its entirety by reference to the provisions of the indentures and the applicable prospectus supplement. You should read these documents carefully to fully understand the terms of the debt securities.

The numerical references in parentheses below are to sections of the indentures. Unless otherwise indicated, capitalized terms used in the following summary that are defined in the indentures have the meanings used in the indentures. As used in this “Description of Debt Securities,” the “company” refers to Motorola Solutions, Inc. and does not, unless the context otherwise indicates, include our subsidiaries.

General

The senior debt securities are unsubordinated obligations of the company. They will be unsecured and will rank equally with each other and all of our other unsubordinated debt, unless otherwise indicated in the applicable prospectus supplement (section 301 of the senior indenture). Each applicable prospectus supplement will set forth, as of the most recent practicable date, the aggregate amount of outstanding debt that would rank junior to the senior debt securities. The subordinated debt securities are subordinated in right of payment to the prior payment in full of our senior indebtedness. See “—Subordinated Indenture Provisions” below. The

6

subordinated debt securities will be unsecured and will rank equally with each other, unless otherwise indicated in the applicable prospectus supplement (section 301 of the subordinated indenture). We will set forth in each applicable prospectus supplement, as of the most recent practicable date, the aggregate amount of our outstanding debt that would rank senior to the subordinated debt securities. The indentures do not limit the aggregate principal amount of debt securities that we may issue thereunder and provide that we may issue debt securities thereunder from time to time in one or more series.

Terms

We will prepare a prospectus supplement for each series of debt securities that we issue. Each prospectus supplement will set forth the applicable terms of the debt securities to which it relates, which may include the following:

We can also establish any other terms and conditions of the debt securities to the extent they do not conflict with the terms of the indentures (section 301 of each indenture). Therefore, you must read the applicable indenture and prospectus supplement carefully to understand the terms of any series of debt securities.

Effective Subordination

The debt securities will be our obligations exclusively. Since our operations are partially conducted through subsidiaries, primarily overseas, our cash flow and therefore our ability to service debt, including the debt securities offered by the applicable prospectus supplement, are partially dependent upon the earnings of our subsidiaries and the distribution of those earnings to, or upon loans or other payments of funds by those subsidiaries to, us. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due pursuant to the debt securities or to make any funds available to us to repay our obligations, whether by dividends, loans or other payments. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to statutory or contractual restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations.

Any right of ours to receive assets of any of our subsidiaries upon their liquidation or reorganization and therefore the right of the holders of the debt securities to participate in those assets will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors.

7

No Limitations on Other Debt

The general provisions of the indentures do not contain any provisions that would limit our ability to incur indebtedness or that would afford holders of debt securities protection in the event of a highly leveraged or similar transaction involving us. However, the indentures do restrict us and our domestic subsidiaries from granting certain security interests on certain of their property or assets unless the debt securities are equally secured. See “—Restrictive Covenants” below.

Open-Ended Indenture

The indentures are “open-ended,” meaning we may issue a number of different series of debt securities, with different terms and conditions, under each of the indentures (section 301 of each indenture). There is no limit on the amount of debt securities we can issue under either indenture, and we already have issued a significant amount of debt securities under the senior indenture.

Defeasance and Covenant Defeasance

Under the indentures, we have the ability to take certain steps to effect a “defeasance” or a “covenant defeasance.” A defeasance allows us to be discharged from any and all obligations in respect of a series of debt securities except for certain obligations to register the transfer or exchange of such debt securities, to replace temporary, destroyed, stolen, lost or mutilated debt securities, to maintain paying agencies and to hold monies for payment in trust. A covenant defeasance allows us to stop complying with certain restrictive covenants relating to:

A covenant defeasance also causes certain events specified in the indentures to no longer be deemed an event of default under the indentures.

To effect a defeasance or a covenant defeasance, we must deposit with the applicable trustee an amount of money or U.S. government securities that, through the payment of interest and principal in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of, and premium, if any, and each installment of interest, if any, on the debt securities of such series at the time such payments are due. We will remain liable for any shortfall between the amount deposited with the trustee and the amount due holders of debt securities upon any acceleration of payment.

We may only effect a defeasance or a covenant defeasance if we have provided a legal opinion that such action will not cause holders of our debt securities to recognize income, gain or loss for federal income tax purposes as a result and that holders will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. The opinion, in the case of a defeasance, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable Federal income tax law occurring after the date of the applicable indenture.

We may further describe in the applicable prospectus supplement the provisions, if any, regarding defeasance or covenant defeasance with respect to the debt securities of a particular series (article fifteen of each indenture).

Restrictive Covenants

Restrictions on Secured Debt

If we or any Domestic Subsidiary incurs or guarantees any Debt secured by a Mortgage on any Principal Property or on any shares of stock or Debt of any Domestic Subsidiary, we must secure the debt securities of each series equally and ratably with (or prior to) such secured Debt, unless, after giving effect to such transaction, the aggregate amount of all such Debt so secured, together with all Attributable Debt in respect of sale and leaseback transactions involving Principal Properties, would not exceed 15% with respect to the senior indenture of the Consolidated Net Tangible Assets of us and our consolidated subsidiaries. See “—Restrictive Covenants—Restrictions on Sales and Leasebacks” below.

This restriction does not apply to, and there will be excluded from secured Debt in any computation under such restriction, Debt secured by:

Restrictions on Sales and Leasebacks

Neither we nor any Domestic Subsidiary may enter into any sale and leaseback transaction involving any Principal Property, completion of construction and commencement of full operation of which has occurred more than 180 days prior thereto, unless:

This restriction will not apply to any sale and leaseback transaction:

Certain Definitions

The following are certain key definitions used in the descriptions above of restrictions on secured debt and sales and leasebacks contained in the senior indenture. These and other definitions are contained in the senior indenture. You should read the applicable indenture to understand these and other restrictions fully.

9

“Attributable Debt” means the total net amount of rent required to be paid during the remaining term of any lease, discounted at the rate per annum borne by the senior debt securities of each series, compounded annually.

“Consolidated Net Tangible Assets” means the aggregate amount of assets, less applicable reserves and other properly deductible items, after deducting from that net amount:

“Domestic Subsidiary” means a Subsidiary of ours except a Subsidiary of ours which neither transacts any substantial portion of its business nor regularly maintains any substantial portion of its fixed assets within the United States, or which is engaged primarily in financing our operations or our Subsidiaries, or both, outside the United States.

“Funded Debt” means all indebtedness for money borrowed having a maturity of more than 12 months from the date of the most recent balance sheet of us and our consolidated subsidiaries or having a maturity of less than 12 months but by its terms being renewable or extendible beyond 12 months from the date of such balance sheet at the option of the borrower.

“Principal Property” includes any single parcel of real estate, any manufacturing plant or warehouse we own or lease or any Domestic Subsidiary owns or leases which is located within the United States and the gross book value, without deduction of any depreciation reserves, of which on the date as of which the determination is being made exceeds 1% of Consolidated Net Tangible Assets, other than any single parcel of real estate, manufacturing plant or warehouse or a portion of any manufacturing plant or warehouse:

“Subsidiary” shall mean any corporation, association, partnership or other business entity of which more than 50% of the total voting stock or other interests (including partnership interests) entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof is at the time owned or controlled, directly or indirectly, by the Company or by one or more other Subsidiaries, or by the Company and one or more other Subsidiaries.

Events of Default

The following are events of default under the indentures with respect to any debt securities:

10

If an event of default with respect to the outstanding debt securities of any series occurs and continues either the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all debt securities of that series to be due and payable immediately; provided that in the case of certain events of bankruptcy, insolvency or reorganization, such principal amount, or portion thereof, will automatically become due and payable. However, at any time after an acceleration with respect to debt securities of any series has occurred, but before a judgment or decree based on such acceleration has been obtained, the holders of a majority in principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration (section 502 of each indenture). For information as to waiver of defaults, see “—Modification and Waiver” below. You must read the applicable prospectus supplement for a description of the acceleration provisions of any debt securities issued as original issue discount or indexed securities.

Subject to the duty of the trustee during default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders, unless such holders have offered the trustee reasonable security or indemnity (section 603 of each indenture). Subject to such indemnification and certain other limitations, the holders of a majority in principal amount of the outstanding debt securities of any series 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 debt securities of that series (section 512 of the senior indenture and section 505 of the subordinated indenture).

We will be required to furnish to the trustee an annual statement as to our performance of certain of our obligations under the applicable indenture and as to any default in such performance (section 1006 of each indenture).

Modification and Waiver

Modifications and amendments of each indenture may be made by us and the trustee with the consent of the holders of (1) a majority with respect to the senior indenture or (2) 66 ²/₃% with respect to the subordinated indenture in principal amount of the outstanding debt securities of each series affected thereby, except that no such modification or amendment may, without the consent of the holder of each outstanding debt security affected thereby:

11

The holders of a majority of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive, insofar as that series is concerned, our compliance with certain restrictive provisions of the applicable indenture (section 1008 of the senior indenture and section 1012 of the subordinated indenture). The holders of a majority of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive any past default under the applicable indenture with respect to debt securities of that series, except a default in the payment of the principal of, or premium, if any, or interest, if any, on any debt security of that series or in respect of any provision which under the applicable indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of that series affected (section 513 of the senior indenture and section 504 of the subordinated indenture).

In addition, we may not modify or amend the subordination provisions of the subordinated indenture without the consent of the holders of each outstanding subordinated debt security affected thereby. Further, no modification or amendment of that type may adversely affect the rights under article sixteen of the subordinated indenture of the holders of senior indebtedness then outstanding without the consent of the requisite holders of senior indebtedness required under the terms of such senior indebtedness (section 902 of the subordinated indenture).

The subordinated indenture contains provisions for convening meetings of the holders of subordinated debt securities of a series issued thereunder if subordinated debt securities of that series are issuable in whole or in part as bearer securities (section 1401 of the subordinated indenture). The trustee for those subordinated debt securities may call a meeting at any time or upon our request or the request of holders of at least 10% in principal amount of the outstanding subordinated debt securities of such series, in any such case upon notice given in accordance with the subordinated indenture (section 1402 of the subordinated indenture). Except for any consent that must be given by each holder of a subordinated debt security affected, and except as described below, any resolution presented at a meeting or adjourned meeting at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding subordinated debt securities of that series. Any resolution with respect to any consent which may be given by the holders of not less than 66 ²/₃% in principal amount of the outstanding subordinated debt securities of a series issued under the subordinated indenture, except for any consent that must be given by each holder of a subordinated debt security affected, may be adopted at a meeting or an adjourned meeting at which a quorum is present only by the affirmative vote of the holders of 66 ²/₃% in principal amount of such outstanding subordinated debt securities of that series. Further, any resolution with respect to any demand, consent, waiver or other action which may be made, given or taken by the holders of a specified percentage, which is less than a majority, in principal amount of the outstanding subordinated debt securities of a series issued under the subordinated indenture may be adopted at a meeting or adjourned meeting at which a quorum is present by the affirmative vote of the holders of such specified percentage in principal amount of the outstanding subordinated debt securities of that series (section 1404 of the subordinated indenture).

Any resolution passed or decision taken at any meeting of holders of subordinated debt securities of any series duly held in accordance with the subordinated indenture with respect thereto will be binding on all holders of subordinated debt securities of that series and the related coupons issued under the subordinated indenture. The quorum at any meeting of holders of a series of subordinated debt securities called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the outstanding subordinated debt securities of such series. However, if any action is to be taken at such meeting with respect to a consent which may be given by the holders of not less than 66 ²/₃% in principal amount of the outstanding subordinated debt securities of a series, the persons holding or representing 66 ²/₃% in principal amount of the outstanding subordinated debt securities of such series issued under that indenture will constitute a quorum (section 1404 of the subordinated indenture).

12

Consolidation, Merger, Conveyance, Transfer or Lease

We may, without the consent of any holders of outstanding debt securities, consolidate or merge with or into, or transfer or lease our assets substantially as an entirety to, any entity, and any other entity may consolidate or merge with or into, or transfer or lease its assets substantially as an entirety to, us, provided that:

Form, Denominations, Exchange, Registration and Transfer

We will issue debt securities as registered securities, which may be issued in global form. Global securities are described below under “—Book-entry; Delivery and Form; Global Securities.” Unless we otherwise provide in the applicable prospectus supplement, we will issue registered securities in denominations of $2,000 and integral multiples of $1,000.

Our registered securities will be exchangeable for other registered securities of the same series.

You may present registered securities for registration of transfer at the office of the trustee, or at the office of any transfer agent we designate without service charge and upon payment of any taxes and other governmental charges (section 305 of each indenture). We may change transfer agents or designate additional transfer agents at any time, except that, we must maintain a transfer agent in each place of payment for such series (section 1002 of each indenture).

If we elect or are required to redeem or exchange particular debt securities, we will not be required to:

Payment and Paying Agents

Unless the applicable prospectus supplement provides otherwise, the place of payment for all registered securities will be New York, New York, U.S.A., and we will initially designate the corporate trust office of the applicable trustee for this purpose. At our option, we may pay interest, if any, on registered securities by check mailed to the address of the person entitled thereto as such person’s address appears in the security register or by wire transfer to an account located in the United States maintained by the person entitled thereto as specified in the security register (sections 307, 1001 and 1002 of each indenture). Unless the applicable prospectus supplement provides otherwise, we will make payment of any installment of interest on registered securities to the person in whose name such registered security is registered at the close of business on the record date for such interest (section 307 of each indenture).

13

Unless the applicable prospectus supplement provides otherwise, we will make all payments of principal of, and premium, if any, and interest, if any, on any debt security that is payable in a currency other than U.S. dollars in U.S. dollars if such currency:

We may designate additional offices or agencies for payment with respect to any debt securities, approve a change in the location of any such office or agency and, except as provided above, rescind the designation of any such office or agency.

All moneys deposited with a paying agent or held for the payment of principal of, or premium, if any, or interest, if any, on any debt security that remains unclaimed at the end of two years after such payment has become due will, at our request, be repaid to us, or discharged from trust, and the holder of such debt security may thereafter look only to us for payment thereof (section 1003 of each indenture).

Book-entry; Delivery and Form; Global Securities

The following will apply to debt securities of any series, unless the prospectus supplement relating to that series provides otherwise.

Upon issuance, we will deposit with, or on behalf of, the depositary and will register in the name of the depositary or a nominee of the depositary one or more “global securities” to represent the debt securities of each series. Unless we otherwise indicate in the prospectus supplement relating to a series of debt securities, The Depository Trust Company will act as the depositary and we will deposit the global securities with, or on behalf of, DTC or its nominee, and we will register registered securities in the name of a nominee of DTC. Except under limited circumstances described below, global securities will not be exchangeable for definitive certificated debt securities.

Upon the issuance of a global security, DTC will credit on its book-entry registration and transfer system the principal amounts of the individual debt securities represented by such global security to the accounts of persons that have accounts with DTC, generally known as DTC participants. Ownership of beneficial interests in a global security will be limited to DTC participants or persons that may hold interests through DTC participants. Ownership of beneficial interests in such global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC with respect to interests of DTC participants and records of DTC participants, with respect to interests of persons who hold through DTC participants. The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to own, pledge or transfer beneficial interest in a global security.

We will make payments of principal of and any interest, and premium, if any, on individual debt securities represented by a global security to DTC or its nominee, as the case may be, as the sole registered owner of such global security and the sole holder of the debt securities represented by the global security for all purposes under the applicable indenture. Neither we nor the trustee, nor any of our agents or the trustee, will have any responsibility or liability for any aspect of DTC’s records relating to or payments made on account of beneficial ownership interests in the global securities representing any debt securities or for maintaining, supervising or reviewing any of DTC’s records relating to those beneficial ownership interests.

14

We have been advised by DTC that, upon receipt of any payment in respect of a global security, DTC will immediately credit DTC participants’ accounts for their pro rata share of such payments. We also expect that payments by DTC participants to owners of beneficial interests in global securities held through such DTC participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name.” These payments will be the sole responsibility of the DTC participants.

Global securities may not be transferred except as a whole by DTC to a nominee of DTC. Global securities representing debt securities are exchangeable for certificated debt securities only if:

Any global securities that are exchangeable as described above shall be exchangeable for certificated debt securities issuable in denominations of $1,000, or $5,000 in the case of bearer debt securities, and integral multiples of $1,000, or $5,000 in the case of bearer debt securities, in excess thereof and registered in the names DTC directs. Subject to the foregoing, global securities are not exchangeable, except for global securities of like denomination to be registered in the name of DTC or its nominee. If we issue debt securities subsequently in registered form, they would thereafter be transferred or exchanged without any service charge at the corporate trust office of the trustee or at any other office or agency we maintain for such purpose.

So long as DTC or its nominee is the registered holder and owner of global securities, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global securities for the purposes of receiving payment on the debt securities, receiving notices and for all other purposes under the applicable indenture and the debt securities. Except as provided above, owners of beneficial interests in global securities will not be entitled to receive physical delivery of debt securities in definitive form and will not be considered the holders thereof for any purpose under the applicable indenture. Accordingly, each person owning a beneficial interest in the global securities must rely on the procedures of DTC and, if such person is not a DTC participant, on the procedures of the DTC participant through which such person owns its interest, to exercise any rights of a holder under the applicable indenture. The indentures provide that DTC may grant proxies and otherwise authorize DTC participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a holder is entitled to give or take under the applicable indenture. We understand that under existing industry practices in the event that we request any action of holders or that an owner of a beneficial interest in global securities desires to give or take any action which a holder is entitled to give or take under the applicable indenture, DTC would authorize the DTC participants holding the relevant beneficial interests to give or take such action, and such DTC participants would authorize beneficial owners owning through such DTC participants to give or take such action or would otherwise act upon the instructions of beneficial owners through them.

DTC has advised us as follows:

15

According to DTC, the foregoing information with respect to DTC has been provided to the industry for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Subordinated Indenture Provisions

Any subordinated securities would be subordinate and junior in right of payment, to the extent set forth in the subordinated indenture, to the prior payment in full of all existing and future senior debt of ours (section 1601 of the subordinated indenture).

Senior debt is defined in the subordinated indenture as the principal of, and premium, if any, and interest on, including interest accruing after the filing of a petition initiating any proceeding pursuant to any bankruptcy law, and other amounts due on or in connection with any debt incurred, assumed or guaranteed by us, whether outstanding on the date of the subordinated indenture or thereafter incurred, assumed or guaranteed, and all renewals, extensions and refundings of any such debt. Excluded from the definition of senior debt are the following:

There are no restrictions in the subordinated indenture on the creation of additional senior debt, or any other indebtedness (section 101 of the subordinated indenture). The prospectus supplement with respect to any subordinated securities will set forth:

16

By reason of such subordination, in the event of dissolution, insolvency, bankruptcy or other similar proceedings, upon any distribution of assets:

Unless the applicable prospectus supplement provides otherwise, in the event that the subordinated securities are declared due and payable prior to their Stated Maturity by reason of the occurrence of an event of default, then we would be obligated to promptly notify holders of senior debt of such acceleration. Unless the applicable prospectus supplement provides otherwise, we may not pay the subordinated securities until 120 days have passed after such acceleration occurs and may thereafter pay the subordinated securities if the terms of the subordinated indenture otherwise permit payment at that time (section 1603 of the subordinated indenture).

Unless the applicable prospectus supplement provides otherwise, we may not make any payment of the principal, and premium, if any, or interest, if any, with respect to any of the subordinated securities, except we may acquire subordinated securities for our common stock or other capital stock or as otherwise set forth in the subordinated indenture, if any default with respect to senior debt occurs and is continuing that permits the acceleration of the maturity thereof and such default is either the subject of judicial proceedings or we receive notice of the default, unless 120 days pass after notice of the default is given and such default is not then the subject of judicial proceedings or the default with respect to the senior debt is cured or the terms of the subordinated indenture otherwise permit the payment or acquisition of the subordinated securities at that time (section 1604 of the subordinated indenture).

The Trustee

The Bank of New York Mellon Trust Company, N.A. is trustee under:

18

DESCRIPTION OF SECURITIES WARRANTS

We may issue warrants for the purchase of our debt securities or common stock, either independently or together with debt securities or common stock. We will issue each series of warrants under a separate warrant agreement between us and a bank or trust company, as agent. The warrant agent will act solely as our agent and will not assume any obligation for any warrant holders. Copies of the forms of warrant agreements and the forms of warrant certificates are filed as exhibits to the registration statement. The following description of certain provisions of the forms of warrant agreements and warrant certificates does not purport to be complete and is qualified in its entirety by reference to all the provisions of the warrant agreements and the warrant certificates.

General

If we offer warrants for the purchase of debt securities, the applicable prospectus supplement will describe their terms, which may include the following:

If we offer warrants for the purchase of our common stock, the applicable prospectus supplement will describe their terms, which may include the following:

19

Warrants for the purchase of our common stock will be offered and exercisable for U.S. dollars only.

Warrants may be exchanged for new warrants of different denominations, may, if in registered form, be presented for registration of transfer and may be exercised at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. No service charge will be made for any permitted transfer or exchange of warrant certificates, but holders must pay any tax or other applicable governmental charge. Prior to the exercise of any warrant to purchase underlying debt securities, holders of such warrants will not have any of the rights of holders of the debt securities purchasable upon such exercise, including the right to receive payments of principal of, or premium, if any, or interest, if any, on the debt securities purchasable upon such exercise or to enforce covenants in the applicable indenture. Prior to the exercise of any warrants to purchase our common stock, holders of such warrants will not have any rights of holders of our common stock purchasable upon such exercise, including the right to receive payments of dividends, if any, on our common stock purchasable upon such exercise or to exercise any applicable right to vote.

Exercise of Warrants

Each warrant will entitle the holder to purchase underlying debt securities or our common stock, as the case may be, at the exercise price described in, or calculable from, the applicable prospectus supplement. Unexercised warrants will become void after the close of business on the expiration date.

Holders can exercise warrants by delivering the exercise price and certain required information to the warrant agent. Warrants will be deemed to have been exercised upon receipt of payment of the exercise price, subject to the receipt, within five business days, of the warrant certificate. Upon receipt of such payment and such warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, issue and deliver the underlying debt securities or our common stock, as the case may be, purchasable upon such exercise. If fewer than all of the warrants represented by a warrant certificate are exercised, we will issue a new warrant certificate for the remaining warrants. The holder of a warrant must pay any tax or other governmental charge imposed in connection with the issuance of underlying debt securities or our common stock purchased upon exercise of a warrant.

Modifications

The warrant agreements and the terms of the warrants may be modified or amended by us and the warrant agent, without the consent of any holder, for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision contained therein, or in any other manner that we deem necessary or desirable and that will not materially adversely affect the interests of the holders of the warrants.

Together with the warrant agent, we may also modify or amend the warrant agreement and the terms of the warrants with the consent of a majority of the holders of the then outstanding unexercised warrants affected thereby. No modification or amendment of that type that accelerates the expiration date, increases the exercise price, reduces the number of outstanding warrants required for consent of any such modification or amendment, or otherwise materially adversely affects the rights of the holders of the warrants, may be made without the consent of each holder affected thereby.

DESCRIPTION OF THE STOCK PURCHASE CONTRACTS AND THE STOCK PURCHASE UNITS

We may issue stock purchase contracts representing contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of our common stock (or a range of numbers of shares pursuant to a predetermined formula) at a future date or dates. The price per share of common stock and the number of shares of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts.

The stock purchase contracts may be issued separately or as a part of units, often known as stock purchase units, consisting of a stock purchase contract and either:

securing the holders’ obligations to purchase the common stock under the stock purchase contracts.

The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner and in certain circumstances we may deliver newly issued prepaid stock purchase contracts, often known as prepaid securities, upon release to a holder of any collateral securing such holder’s obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. The description in the applicable prospectus supplement will not contain all of the information that you may find useful. For more information, you should review the stock purchase contracts, the collateral arrangements and depositary arrangements, if applicable, relating to such stock purchase contracts or stock purchase units and, if applicable, the prepaid securities and the document pursuant to which the prepaid securities will be issued. These documents will be filed with the SEC promptly after the offering of the stock purchase contracts or stock purchase units. Material United States federal income tax considerations applicable to the stock purchase contracts and the stock purchase units will also be discussed in the applicable prospectus supplement.

If underwriters are used in the sale, the underwriters will acquire the offered securities for their own account and may resell them from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The offered securities may be offered either to the public through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate. Unless otherwise set forth in a prospectus supplement, the obligations of the underwriters to purchase any series of securities will be subject to certain conditions precedent and the underwriters will be obligated to purchase all of such series of securities if any are purchased.

In connection with underwritten offerings of the offered securities and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the offered securities at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below:

These transactions may be effected on the New York Stock Exchange, in the over-the-counter market, or otherwise. Underwriters are not required to engage in any of these activities, or to continue such activities if commenced.

If a dealer is used in the sale, we will sell such offered securities to the dealer, as principal. The dealer may then resell the offered securities to the public at varying prices to be determined by that dealer at the time for resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

Offered securities may be sold directly by us to one or more institutional purchasers, or through agents designated by us from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Any agent involved in the offer or sale of the offered securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth in the prospectus supplement relating to that offering, unless otherwise indicated in such prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

Any person participating in the distribution of common stock registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our common stock by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our common stock to engage in market-making activities with respect to our common stock. These restrictions may affect the marketability of our common stock and the ability of any person or entity to engage in market-making activities with respect to our common stock.

Other than our common stock, which is listed on the New York Stock Exchange, each of the securities issued hereunder will be a new issue of securities, will have no prior trading market, and may or may not be listed on a national securities exchange.
