DESCRIPTION OF THE NOTES

This prospectus supplement contains a description of the material terms of the notes but does not purport to be complete. This description of the notes supplements and, to the extent inconsistent therewith, replaces, the section entitled “Description of Debt Securities” included in the accompanying prospectus. You should read the accompanying prospectus and this prospectus supplement together for a more complete description of the indenture and the notes. Capitalized terms used in this “Description of the Notes” have the meanings specified in the indenture and are generally summarized in this section or under “Description of Debt Securities—Certain Definitions” in the accompanying prospectus. References to “we,” “us” and “our” in this “Description of the Notes” refer only to The Western Union Company and not any of its subsidiaries.

General

Principal, Maturity and Interest

We will issue the notes under an indenture, dated as of November 17, 2006, between us and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by a supplemental indenture, dated as of September 6, 2007, between us and the Trustee. We refer to the indenture, as supplemented by the supplemental indenture, as the indenture. We may issue additional notes of either series from time to time after this offering. See “—Issuance of Additional Notes.”

We will issue the floating rate notes as a separate series of debt securities pursuant to the indenture with an initial aggregate principal amount of $250,000,000 .

We will issue the new 2022 notes as additional notes of the same series as the 2022 notes issued pursuant to the indenture. The 2022 notes, comprising $400.0 million aggregate principal amount of our 3.600% Notes due 2022, were issued under the indenture on March 15, 2017. Upon completion of the offering being made pursuant to this prospectus supplement, there will be $500.0 million aggregate principal amount of 2022 notes outstanding. The new 2022 notes will have the same terms (except for issue date and public offering price) and CUSIP number as, and will be fully fungible for U.S. federal income tax purposes with, the 2022 notes, and the new 2022 notes and the 2022 notes will be treated as part of a single series for all purposes under the indenture.

The notes will be issued in book-entry form only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The floating rate notes will mature on May 22 , 2019. The new 2022 notes will mature on March 15, 2022. If the maturity date of the notes of either series is not a Business Day then the principal amount of such notes plus accrued and unpaid interest thereon shall be paid on the next succeeding Business Day with the same effect as if payment were made on the maturity date, and no interest shall accrue for the maturity date, or thereafter.

Interest on the floating rate notes will accrue from the issue date or from the most recent date to which interest has been paid or provided for to the date immediately preceding the next succeeding interest payment date. Interest on the new 2022 notes will accrue from March 15, 2017, the original issue date of the 2022 notes, or from the most recent date to which interest has been paid or provided for to the date immediately preceding the next succeeding interest payment date.

If any interest payment date of the notes of either series falls on a day that is not a Business Day, then payment shall be made on the next succeeding Business Day, without additional interest and with the same effect as if it were made on the originally scheduled date, unless, with respect to the floating rate notes, the next succeeding Business Day is in the next succeeding calendar month, in which case payment shall be made on the immediately preceding Business Day without additional interest and with the same effect as if it were made on the originally scheduled date.

S-18

Interest on the Floating Rate Notes

Interest on the floating rate notes will accrue at a rate per annum, reset quarterly, equal to three-month LIBOR plus 0.80% , as determined by the calculation agent (the “Calculation Agent”), which shall initially be the Trustee. We will pay interest on the floating rate notes quarterly in arrears to holders of record at the close of business on February 7, May 7, August 7 or November 7 immediately preceding the interest payment date on February 22, May 22, August 22 and November 22 of each year, beginning November 22 , 2017.

The amount of interest for each day that the floating rate notes are outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of such notes then outstanding. The amount of interest to be paid on the floating rate notes for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 3.876545% (or .03876545) being rounded to 3.87655% (or .0387655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

The interest rate on the floating rate notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

The Calculation Agent will, upon the request of any holder of floating rate notes, provide the interest rate then in effect with respect to the floating rate notes. All calculations made by the Calculation Agent in the absence of manifest error will be conclusive for all purposes and binding on us and the holders of the floating rate notes.

“Determination Date” with respect to an Interest Period will be the second London Banking Day preceding the first day of such Interest Period.

“Interest Period” means the period commencing on and including an interest payment date and ending on and including the day immediately preceding the next succeeding interest payment date, with the exception that the first Interest Period shall commence on and include the issue date and end on and include November 21 , 2017.

“Interest Reset Date” means the first day of any Interest Period.

“LIBOR,” with respect to an Interest Period, will be the rate (expressed as a percentage per annum) for deposits in U.S. dollars for a three-month period beginning on the second London Banking Day after the Determination Date that appears on the display on Page LIBOR01 of Reuters (or any successor service) for the purpose of displaying the London interbank offered rates of major banks for U.S. dollars (or such other page as may replace that page on that service (or any successor service) for the purpose of displaying such rates) as of 11:00 a.m., London time, on the Determination Date. If such page does not include such a rate or is unavailable on a Determination Date, we will request the principal London office of each of four major banks in the London interbank market, as selected by us, to provide such bank’s offered quotation (expressed as a percentage per annum), as of approximately 11:00 a.m., London time, on such Determination Date, to prime banks in the London interbank market for deposits in a Representative Amount in U.S. dollars for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two such offered quotations are so provided, the rate for the Interest Period will be the arithmetic mean of such quotations. If fewer than two such quotations are so provided, we will request each of three major banks in New York City, as selected by us, to provide such bank’s rate (expressed as a percentage per annum), as of approximately 11:00 a.m., New York City time, on such Determination Date, for loans in a Representative Amount in U.S. dollars to leading European banks for a three-month period beginning on the second London Banking Day after the Determination Date. If at least two such rates are so provided, the rate for the Interest Period will be the arithmetic mean of such rates. If fewer than two such rates are so provided, then the rate for the Interest Period will be the rate in effect with respect to the immediately preceding Interest Period.

S-19

“London Banking Day” is any day on which dealings in U.S. dollars are transacted or, with respect to any future date, are expected to be transacted in the London interbank market.

“Representative Amount” means a principal amount of not less than $1,000,000 for a single transaction in the relevant market at the relevant time.

Interest on the New 2022 Notes

The new 2022 notes will bear interest at a rate of 3.600% per annum. We will pay interest on the new 2022 notes semi-annually in arrears to holders of record at the close of business on March 1 or September 1 immediately preceding the interest payment date on March 15 and September 15 of each year, beginning September 15, 2017. Interest on the new 2022 notes will be computed on the basis of a 360-day year of twelve 30-day months. Accrued interest on the new 2022 notes from March 15, 2017, the date of issuance of the $400 million aggregate principal amount of 2022 notes we previously issued, to August 22 , 2017, the original issue date of the new 2022 notes, is equal to approximately $15.70 per $1,000 principal amount of new 2022 notes.

Interest Rate Adjustment for the New 2022 Notes

The interest rate payable on the new 2022 notes will be subject to adjustments from time to time if Moody’s (or, if applicable, any Substitute Rating Agency (as defined below)) or S&P (or, if applicable, any Substitute Rating Agency), downgrades (or subsequently upgrades) the debt rating assigned to the new 2022 notes, as set forth below.

If the rating from Moody’s or S&P (or, in either case if applicable, any Substitute Rating Agency) with respect to the new 2022 notes (each, an “Applicable Rating Agency,” and collectively, the “Applicable Rating Agencies”) is decreased to a rating set forth in the immediately following table with respect to that Applicable Rating Agency, the per annum interest rate on the new 2022 notes will increase from that set forth on the cover page of this prospectus supplement by the percentage set forth opposite that rating:

If at any time the interest rate on the new 2022 notes has been adjusted upward as a result of a decrease in a rating by an Applicable Rating Agency and that Applicable Rating Agency subsequently increases its rating with respect to the new 2022 notes to any of the threshold ratings set forth above, the per annum interest rate on the new 2022 notes will be decreased such that the per annum interest rate equals 3.600% plus the percentage set forth opposite the rating in effect immediately following the increase in the table above; provided that if Moody’s or any Substitute Rating Agency subsequently increases its rating of the new 2022 notes to “Baa3” (or its equivalent if with respect to any Substitute Rating Agency) or higher and S&P or any Substitute Rating Agency subsequently increases its rating of the new 2022 notes to “BBB-” (or its equivalent if with respect to any Substitute Rating Agency) or higher, the interest rate on the new 2022 notes will be decreased to 3.600% per annum.

S-20

No adjustment in the interest rate of the new 2022 notes shall be made solely as a result of an Applicable Rating Agency ceasing to provide a rating. If at any time less than two Applicable Rating Agencies provide a rating of the new 2022 notes, we will use our commercially reasonable efforts to obtain a rating of the new 2022 notes from another nationally recognized statistical rating organization, to the extent one exists, and if another nationally recognized statistical rating organization rates the new 2022 notes (such organization, as certified by a resolution of our board of directors, a “Substitute Rating Agency”), for purposes of determining any increase or decrease in the per annum interest rate on the new 2022 notes pursuant to the table above (a) such Substitute Rating Agency will be substituted for the last Applicable Rating Agency to provide a rating of the new 2022 notes but which has since ceased to provide such rating, (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the table above with respect to such Substitute Rating Agency, such ratings shall be deemed to be the equivalent ratings used by Moody’s and S&P in such table and (c) the per annum interest rate on the new 2022 notes will increase or decrease, as the case may be, such that the interest rate equals 3.600% plus the appropriate percentage, if any, set forth opposite the rating from such Substitute Rating Agency in the table above (taking into account the provisions of clause (b) above). For so long as (i) only one Applicable Rating Agency provides a rating of the new 2022 notes, any increase or decrease in the interest rate of the new 2022 notes necessitated by a reduction or increase in the rating by that Applicable Rating Agency shall be twice the applicable percentage set forth in the table above and (ii) no Applicable Rating Agency provides a rating of the new 2022 notes, the interest rate on the new 2022 notes will increase to, or remain at, as the case may be, 5.600%.

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s, S&P or any Substitute Rating Agency, shall be made independent of (and in addition to) any and all other adjustments. In no event shall (1) the per annum interest rate on the new 2022 notes be reduced below 3.600% or (2) the per annum interest rate on the new 2022 notes exceed 5.600%.

Any interest rate increase or decrease described above on the new 2022 notes will take effect from the first interest payment date following the date on which a rating change occurs that requires an adjustment in the interest rate of the new 2022 notes. If Moody’s or S&P (or any Substitute Rating Agency) changes its rating of the new 2022 notes more than once prior to any particular interest payment date, the last change by such agency prior to such interest payment date will control for purposes of any interest rate increase or decrease with respect to the new 2022 notes described above relating to such Applicable Rating Agency’s action.

The interest rate on the new 2022 notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any Applicable Rating Agency) if the new 2022 notes become rated “A3” (or its equivalent) or higher by Moody’s (or any Substitute Rating Agency) and “A-” (or its equivalent) or higher by S&P (or any Substitute Rating Agency), or one of those ratings if only rated by one Applicable Rating Agency, in each case with a stable or positive outlook.

Ranking

The notes will be our senior unsecured obligations and rank equally in right of payment with our other existing and future senior unsecured obligations.

We conduct all of our operations through our subsidiaries. Our rights and the rights of our creditors, including the holders of the notes, to participate in the distribution of assets of any of our subsidiaries upon the liquidation or reorganization of that subsidiary or otherwise will be subject to the prior claims of the subsidiary’s creditors, except to the extent that we may be a creditor with recognized claims against the subsidiary. However, the notes will be obligations exclusively of The Western Union Company and will not be guaranteed by any of our subsidiaries. As a result, the notes will be effectively junior to all existing and future indebtedness and other obligations of our subsidiaries, which means that creditors of our subsidiaries will be paid from their assets

S-21

before holders of the notes would have any claims to those assets. As of June 30, 2017, our subsidiaries had outstanding $210 million of total indebtedness, including letters of credit and bank guarantees but excluding intercompany indebtedness.

The indenture does not limit the amount of debt securities or any other debt (whether secured or unsecured or whether subordinated or unsubordinated) which we or, with respect to the notes, our subsidiaries may incur. However, the indenture provides that neither we nor any of our Restricted Subsidiaries (as defined under “Description of Debt Securities—Certain Definitions” in the accompanying prospectus) may subject certain of our property or assets to certain encumbrances unless the notes are secured equally and ratably with or prior to that other secured Indebtedness. Certain other covenants are applicable to the notes as described in the accompanying prospectus. See “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

No Sinking Fund

The notes will not be entitled to any sinking fund.

Issuance of Additional Notes

In addition to the notes, we may issue from time to time other series of debt securities under the indenture consisting of debentures, notes or other evidences of indebtedness that are separate from and independent of the notes. The indenture does not limit the amount of debt securities or any other debt (whether secured or unsecured or whether subordinated or unsubordinated) which we or our subsidiaries may incur.

We may from time to time, without the consent of, or notice to, the holders of any series of notes, reopen the series of debt securities of which such series of notes is a part and issue additional notes having the same ranking and the same interest rate, maturity and other terms as such series of notes, except for the public offering price and the issue date and, if applicable, the initial interest accrual date, the initial Interest Reset Date and the initial interest payment date. Any such additional notes having similar terms, together with the other notes of such series, will constitute a single series of debt securities under the indenture. If, however, any such additional notes are not fungible with the other notes of such series for U.S. federal income tax purposes, the additional notes will have a separate CUSIP number. No such additional notes may be issued if an event of default has occurred and is continuing with respect to the series of debt securities of which such notes are a part. Unless the context otherwise requires, for all purposes of the indenture and this “Description of the Notes,” references to the notes include any additional notes of the same series actually issued.

Payment and Paying Agents

We will maintain in the place of payment for the notes an office or agency where the notes may be presented or surrendered for payment or for registration of transfer or exchange and where holders may serve us with notices and demands in respect of the notes and the indenture.

We will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If we fail to maintain any required office or agency or fail to furnish the Trustee with the address of such office or agency, presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustee. We have appointed the Trustee as our agent to receive all presentations, surrenders, notices and demands with respect to the notes.

Optional Redemption of the New 2022 Notes

The new 2022 notes will be redeemable, in whole or in part, at any time and from time to time prior to February 15, 2022 (the date that is one month prior to the stated maturity date of the 2022 notes) (the “Par Call Date”), at a redemption price equal to the greater of (i) 100% of the principal amount of the 2022 notes to be

S-22

redeemed, and (ii) as determined by the Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on the 2022 notes being redeemed (not including any portion of such payments of interest accrued as of the date of redemption), discounted to the Par Call Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus accrued but unpaid interest thereon to, but excluding, the date of redemption.

In addition, at any time and from time to time on or after the Par Call Date, the new 2022 notes will be redeemable, in whole or in part, at a redemption price equal to 100% of the principal amount of the 2022 notes to be redeemed, plus accrued but unpaid interest thereon to, but excluding, the date of redemption.

Notice of any redemption will be mailed (or sent electronically in accordance with applicable DTC procedures) at least 30 days, but not more than 60 days, before the redemption date to each registered holder of 2022 notes to be redeemed. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the new 2022 notes or portion thereof called for redemption.

We are not required (i) to register, transfer or exchange 2022 notes during the period from the opening of business 15 days before the day a notice of redemption relating to the 2022 notes selected for redemption is sent to the close of business on the day that notice is sent, or (ii) to register, transfer or exchange any such note so selected for redemption, except for the unredeemed portion of any note being redeemed in part.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the 2022 notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate notes of comparable maturity to the remaining term of the 2022 notes.

“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of three Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Quotation Agent obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such quotations.

“Quotation Agent” means a Reference Treasury Dealer appointed by us.

“Reference Treasury Dealer” means (i) Barclays Capital Inc., Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer and (ii) any two other Primary Treasury Dealers selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by us, 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 Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming 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.

S-23

Change of Control

If a Change of Control Triggering Event occurs with respect to a series of notes, unless, with respect to the new 2022 notes, we have exercised our right to redeem the new 2022 notes as described above, we will be required to make an offer (a “Change of Control Offer”) to each holder of that series of notes to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of that holder’s notes of such series on the terms set forth in such notes. In a Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased, plus accrued and unpaid interest, if any, on the notes repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at our option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed (or sent electronically in accordance with applicable DTC procedures) to holders of the applicable series of notes, with a copy to the Trustee, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such notes on the date specified in the applicable notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed or sent (a “Change of Control Payment Date”). The notice will, if mailed or sent prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the applicable Change of Control Payment Date.

On each Change of Control Payment Date with respect to a series of notes, we will, to the extent lawful: 

We will not be required to make a Change of Control Offer with respect to a series of notes upon the occurrence of a Change of Control Triggering 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 us and the third party purchases all notes of such series properly tendered and not withdrawn under its offer. In addition, we will not repurchase any notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

Unless, with respect to the new 2022 notes, we exercise our right to redeem such notes, we will be required to comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of any notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Offer provisions of any notes, we will be required to comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of any notes by virtue of any such conflict and compliance.

If holders of not less than 90% in aggregate principal amount of the outstanding notes of the series subject to the Change of Control Triggering Event properly tender and do not withdraw such notes in a Change of Control Offer (or an offer made by a third party as described above) and we, or any third-party making an offer in lieu of us, as described above, purchase all of the notes of such series properly tendered and not withdrawn by such holders, we or the third party making such offer will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or offer by such third party described above, to redeem all notes of such series that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment.

S-24

If a Change of Control Offer is made, there can be no assurance that we will have available funds sufficient to make the Change of Control Payment for all of the notes that may be tendered for repurchase.

For purposes of the Change of Control Offer provisions of each series of notes, the following terms will be 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 more series of related transactions, of our assets and the assets of our subsidiaries substantially as an entirety or as an entirety, taken as a whole, to any person, other than our company or one of our subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any person becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of our outstanding voting stock or other voting stock into which our voting stock is reclassified, consolidated, exchanged or changed in such transaction, measured by voting power rather than number of shares; (3) we consolidate with, or merge with or into, any person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding voting stock or the voting stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of our voting stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the outstanding voting stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; (4) the first day on which a majority of the members of our board of directors are not continuing directors; or (5) the adoption of a plan relating to our liquidation or dissolution. Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control under clause (2) or (3) above if (i) we become a direct or indirect wholly owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of our voting stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding company. The term “person,” as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act.

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

“Continuing directors” means, as of any date of determination, any member of our board of directors who (1) was a member of such board of directors on the date such series of notes was initially issued or (2) was nominated for election, elected or appointed 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, election or appointment (either by a specific vote or resolution adopted by our board of directors or by approval by our board of directors of our proxy statement in which such member was named as a nominee for election as a director).

“Fitch” means Fitch Inc., and its successors.

“Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s, BBB- (or the equivalent) by S&P and BBB- (or the equivalent) by Fitch, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by us.

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

“Rating Agencies” means, with respect to the applicable series of notes (1) each of Moody’s, S&P and Fitch; and (2) if any or all of Moody’s, S&P or Fitch ceases to rate such series of notes or fails to make a rating of such series of notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Exchange Act selected by us (as certified by a resolution of our board of directors) as a replacement agency for Moody’s, S&P or Fitch, or all of them, as the case may be.

S-25

“Rating Event” means, with respect to the applicable series of notes, the rating on such series of notes is lowered by all three of the Rating Agencies from an Investment Grade Rating to below an Investment Grade Rating, in any case on any day during the period (which period will be extended so long as the rating of such series of notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) commencing upon the first public notice by us of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following the consummation of the Change of Control; provided, however, that a Rating Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Rating Event for purposes of the definition of Change of Control Triggering Event) if any of the Rating Agencies does not announce or publicly confirm or inform us that the reduction in ratings 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 has been consummated at the time of the Rating Event).

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

“Voting stock” means, with respect to any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date, 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.

Our obligation to purchase any series of notes following a Change of Control Triggering Event is subject to the provisions described in the section titled “Discharge, Legal Defeasance and Covenant Defeasance” in this prospectus supplement.

Discharge, Legal Defeasance and Covenant Defeasance

We may be discharged from all of our obligations with respect to the floating rate notes, as described under “Description of Debt Securities—Discharge, Legal Defeasance and Covenant Defeasance” in the accompanying prospectus, but only during the Interest Period in which the floating rate notes mature. The floating rate notes shall not be subject to legal defeasance or covenant defeasance.

We may be discharged from all of our obligations with respect to the outstanding 2022 notes, be discharged from our obligations with respect to the 2022 notes (except as otherwise specified in the indenture) or be released from our obligation to comply with the provisions of the indenture with respect to the 2022 notes, as described under “Description of Debt Securities—Discharge, Legal Defeasance and Covenant Defeasance” in the accompanying prospectus.

The Trustee Under the Indenture

We maintain ordinary banking relationships and, from time to time, obtain credit facilities and lines of credit with a number of banks, including the Trustee, Wells Fargo Bank, National Association. Neither the Trustee nor any paying agent shall be responsible for monitoring our rating status, making any request upon any Rating Agency, or determining whether any Rating Event has occurred. The transferor of any note shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code (as defined under “Material U.S. Federal Income Tax Considerations” below). The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information. In connection with any proposed exchange of a certificated note for a global note, we or DTC shall be required to provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

S-26

Governing Law

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

Other Terms of the Notes

With respect to the floating rate notes, the term “Financing Lease” means any lease of property, real or personal, the obligations of the lessee in respect of which are required in accordance with GAAP as it exists on August 15, 2017 to be capitalized on a balance sheet of the lessee.

With respect to the new 2022 notes, the term “Financing Lease” means any lease of property, real or personal, the obligations of the lessee in respect of which are required in accordance with GAAP as it existed on March 8, 2017 to be capitalized on a balance sheet of the lessee.

Book-Entry, Delivery and Form

Global Notes

We will issue each series of the notes in the form of one or more global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., (as nominee of DTC) or such other name as may be requested by an authorized representative of DTC.

DTC, Clearstream and Euroclear

Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold interests in the global notes through either DTC (in the United States) or Clearstream Banking, S.A., Luxembourg (“Clearstream”), or Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) in Europe, either directly if they are participants in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC.

DTC has advised us as follows:

S-27

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

The Euroclear System was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear Operator is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission. As the operator of a securities settlement system, the Euroclear Operator is also overseen by the National Bank of Belgium.

We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, the underwriters or the Trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

We expect that under procedures established by DTC:

S-28

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. DTC has no knowledge of the actual beneficial owners of the notes; DTC’s records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or a global note.

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

Redemption notices will be sent to DTC. If less than all of the notes of a series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such series to be redeemed.

In any case where a vote may be required with respect to the notes of any series, neither DTC nor its nominee will consent or vote with respect to such notes. Under its usual procedures DTC mails an omnibus proxy to Western Union as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts interests in the notes of the series are credited on the record date (identified in the listing attached to the omnibus proxy).

Neither we nor the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, Clearstream or Euroclear, or for maintaining, supervising or reviewing any records of those organizations relating to the notes.

Payments on the notes represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

Distributions on the notes held beneficially through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

S-29

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

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

In any case where we have made a tender offer for the purchase of any notes, a beneficial owner must give notice through a participant to a tender agent to elect to have its notes purchased or tendered. The beneficial owner must deliver notes by causing the direct participants to transfer the participant’s interest in the notes, on DTC’s records, to a tender agent. The requirement for physical delivery of notes in connection with an optional tender or a mandatory purchase is satisfied when the ownership rights in the notes are transferred by direct participants on DTC’s records and followed by a book-entry credit of tendered notes to the tender agent’s DTC account.

Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable, and will be settled using the procedures applicable to conventional EuroBonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

S-30

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

The information in this section regarding DTC, Clearstream and Euroclear and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of that information.

Certificated Notes

We will issue certificated notes of a series of notes to each person that DTC identifies as the beneficial owner of such series of notes represented by a global note upon surrender by DTC of the global note if:

Neither we nor the Trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of any series of the notes. We and the Trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the certificated notes to be issued.

S-31

DESCRIPTION OF DEBT SECURITIES

We will issue the debt securities in one or more series. Debt securities will be issued under the indenture dated as of November 17, 2006, as supplemented by the supplemental indenture dated as of September 6, 2007, between us and Wells Fargo Bank, National Association, as trustee, or any other indenture which we identify in a prospectus supplement (we refer to the November 17, 2006 indenture or any such other indenture, in each case as supplemented from time to time, as the “indenture”). We have summarized below the material provisions of the indenture. However, because this summary is not complete, it is subject to and is qualified in its entirety by reference to the indenture. In this “Description of Debt Securities,” “we,” “us,” “our” and similar words refer to The Western Union Company and not any of its Subsidiaries (as defined below under “—Certain Definitions”).

General

The debt securities will be our unsecured obligations and rank on a parity with our other unsecured and unsubordinated indebtedness.

We primarily conduct our operations through our Subsidiaries. Our rights and the rights of our creditors, including the holders of the debt securities, to participate in the distribution of assets of any of our Subsidiaries upon the liquidation or reorganization of that Subsidiary or otherwise will be subject to the prior claims of the Subsidiary’s creditors, except to the extent that we may be a creditor with recognized claims against the Subsidiary or such Subsidiary guarantees the debt securities. As a result, the debt securities will be effectively subordinated to existing and future liabilities of our Subsidiaries.

We may issue the debt securities in one or more series, as authorized from time to time by our board of directors, any committee of our board of directors or any duly authorized officer. The indenture does not limit our ability to incur additional indebtedness, nor does it afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving our company. However, the indenture provides that neither we nor any Restricted Subsidiary may subject certain of our property or assets to any mortgage or other encumbrance unless the debt securities are secured equally and ratably with or prior to that other secured indebtedness. See “—Certain Covenants” below. Reference is made to the applicable prospectus supplement for information with respect to any additions to, or modifications or deletions of, the events of default or covenants described below.

We will describe in a supplement to this prospectus the particular terms of any debt securities being offered, any modifications of or additions to the general terms of the debt securities and any U.S. Federal income tax considerations that may be applicable in the case of offered debt securities. Accordingly, you should read both the prospectus supplement relating to the particular debt securities being offered and the general description of debt securities set forth in this prospectus before investing.

The applicable prospectus supplement will describe specific terms relating to the series of debt securities being offered. These terms will include some or all of the following:

9

If we issue original issue discount securities, we will also describe in the applicable prospectus supplement the U.S. Federal income tax consequences and other special considerations applicable to those securities.

We are not required to issue all of the debt securities of a series at the same time, and debt securities of the same series may vary as to interest rate, maturity and other provisions. Unless otherwise provided, the aggregate principal amount of a series may be increased and additional debt securities of such series may be issued.

Denominations, Exchange, Registration and Transfer

Unless otherwise specified in the applicable prospectus supplement, the debt securities of any series will be issued only as registered securities, in global or certificated form and in denominations of $1,000 and any integral multiple thereof, and will be payable only in U.S. dollars. For more information regarding debt securities issued in global form, see “—Book-Entry, Delivery and Form” below. Unless otherwise indicated in the applicable prospectus supplement, any debt securities we issue in bearer form will have coupons attached.

Registered debt securities of any series will be exchangeable for other registered debt securities of the same series in the same aggregate principal amount and having the same stated maturity date and other terms and conditions. If so provided in the applicable prospectus supplement, to the extent permitted by law, debt securities of any series issued in bearer form which by their terms are registrable as to principal and interest may be exchanged, at the option of the holders, for registered debt securities of the same series in the same aggregate principal amount and having the same stated maturity date and other terms and conditions, upon surrender of those securities at the corporate trust office of the trustee or at any other office or agency designated by us for the purpose of making any such exchanges. Except in certain limited circumstances, debt securities issued in bearer form with coupons surrendered for exchange must be surrendered with all unmatured coupons and any matured coupons in default attached thereto.

10

Upon surrender for registration of transfer of any registered debt security of any series at the office or agency maintained for that purpose, we will execute, and the trustee will authenticate and deliver, in the name of the designated transferee, one or more new registered debt securities of the same series in the same aggregate principal amount of authorized denominations and having the same stated maturity date and other terms and conditions. We may not impose any service charge, other than any required tax or other governmental charge, on the transfer or exchange of debt securities.

We are not required (i) to issue, register the transfer of or exchange debt securities of any series during the period from the opening of business 15 days before the day a notice of redemption relating to debt securities of that series selected for redemption is sent to the close of business on the day that notice is sent, or (ii) to register the transfer of or exchange any debt security so selected for redemption, except for the unredeemed portion of any debt security being redeemed in part.

Payment and Paying Agents

We will maintain in each place of payment for those debt securities an office or agency where the debt securities may be presented or surrendered for payment or for registration of transfer or exchange and where holders may serve us with notices and demands in respect of the debt securities and the indenture.

We will give prompt written notice to the trustee of the location, and any change in the location, of such office or agency. If we fail to maintain any required office or agency or fail to furnish the trustee with the address of such office or agency, presentations, surrenders, notices and demands may be made or served at the corporate trust office of the trustee and at the principal London office of the trustee. We have appointed the trustee as our agent to receive all presentations, surrenders, notices and demands with respect to the applicable series of debt securities.

Certain Covenants

Unless otherwise specified in the applicable prospectus supplement, the following covenants apply to the debt securities:

Limitation on Mortgages and Liens . Neither we nor any of our Restricted Subsidiaries may create or assume, except in favor of us or one of our wholly owned Subsidiaries, any Lien upon any Principal Facility (as defined below under “—Certain Definitions”) without equally and ratably securing any debt securities then outstanding. However, this limitation does not apply to certain permitted Liens as described in the indenture, including:

11

Limitation on Sale and Leaseback Transactions . Neither we nor any of our Subsidiaries may sell any Principal Facility owned on the date of the indenture with the intention of taking back a lease of that facility for a period of more than 36 months other than certain computer hardware leases, unless:

Covenant to File Reports . We will file with the trustee, within 15 days after we have filed with the SEC, copies of the annual reports and of the information, documents, and other reports which we have so filed with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act.

Merger or Consolidation

We may not consolidate with or merge into any other entity or sell, lease, convey, assign, transfer or otherwise dispose of our properties and assets substantially as an entirety or as an entirety to any person, unless:

12

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer, or other disposition of the properties and assets substantially as an entirety or as an entirety of one or more of our Subsidiaries, which properties and assets, if held by us instead of such Subsidiary or Subsidiaries, would constitute our properties and assets substantially as an entirety or as an entirety on a consolidated basis, shall be deemed to be the transfer of our properties and assets substantially as an entirety or as an entirety.

Events of Default

“Event of Default” means, with respect to a series of debt securities, any of the following events:

In general, the trustee is required to give notice of a default known to it with respect to a series of debt securities to the holders of debt securities of such series within 90 days after it occurs. However, the trustee may withhold notice of any default (except a default in payment of principal or interest on any debt security of such series) if the trustee determines it is in the interest of the holders of debt securities of such series to do so.

Our failure to comply with Section 314(a) of the Trust Indenture Act of 1939, as amended (relating to the filing of reports, information and other documents with the SEC), shall not constitute a Default or an Event of Default with respect to any series of debt securities.

13

If there is a continuing Event of Default with respect to a series of debt securities, then the trustee or the holders of at least 25% in principal amount of the debt securities of such series may require us to repay the principal amount on the debt securities of such series immediately. Upon payment of the principal or other specified amount, our obligations in respect of the payment of principal of the debt securities of such series will terminate.

Subject to the provisions of the indenture relating to the duties of the trustee, in the case of a continuing Event of Default with respect to a series of debt securities, the trustee may refuse to exercise any of its rights or powers under the indenture with respect to such series of debt securities at the request, order or direction of any of the holders of debt securities of such series unless it first receives reasonable indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request, order or direction. Subject to this limitation, the holders of a majority in principal amount of the outstanding debt securities of the affected series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the indenture with respect to such series of debt securities or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

At any time before a judgment or decree for payment of money due has been obtained by the trustee as provided in the indenture following a declaration of acceleration with respect to a series of debt securities, the holders of a majority in principal amount of the outstanding debt securities of such series may rescind and annul such declaration and its consequences if:

No such rescission and annulment will affect any subsequent default or impair any right consequent thereon.

We are required to provide the trustee with an officers’ certificate each fiscal year stating whether or not we have complied with all conditions and covenants under the indenture.

Modification or Waiver

We and the trustee may, at any time and from time to time, amend the indenture without the consent of the holders of outstanding debt securities for any of the following purposes:

14

In addition, we and the trustee may modify the indenture and the debt securities of any series with the consent of the holders of not less than a majority in principal amount of each series of outstanding debt securities affected by such modification to add, change or eliminate any provision of, or to modify the rights of holders of debt securities of such series under, the indenture. But we may not take any of the following actions without the consent of each holder of outstanding debt securities affected thereby:

A modification with respect to one or more particular series of debt securities and related coupons, if any, will not affect the rights under the indenture of the holders of debt securities of any other series and related coupons, if any.

The holders of a majority in principal amount of the outstanding debt securities of all series affected may, on behalf of the holders of all debt securities of such series, waive any past default under the indenture with respect to the debt securities of such series, except a default (i) in the payment of principal of, premium, if any, or interest on such series or (ii) in respect of a covenant or provision which, as described above, cannot be modified or amended without the consent of each holder of debt securities of such series. Upon any such waiver, the default will cease to exist with respect to the debt securities of such series and any Event of Default arising therefrom will be deemed to have been cured for every purpose of the debt securities of such series under the indenture, but the waiver will not extend to any subsequent or other default or impair any right consequent thereon.

15

We may elect in any particular instance not to comply with certain covenants set forth in the indenture or the debt securities of any series (except as otherwise provided in the covenants described above under “—Certain Covenants”) if, before the time for such compliance, the holders of at least a majority in principal amount of the outstanding debt securities of such series either waive compliance in that instance or generally waive compliance with those provisions, but the waiver may not extend to or affect any term, provision or condition except to the extent expressly so waived, and, until the waiver becomes effective, our obligations and the duties of the trustee in respect of any such provision will remain in full force and effect.

Discharge, Legal Defeasance and Covenant Defeasance

We may be discharged from all of our obligations with respect to the outstanding debt securities of any series (except as otherwise provided in the indenture) when:

We may elect (i) to be discharged from our obligations with respect to the outstanding debt securities of any series (except as otherwise specified in the indenture) or (ii) to be released from our obligation to comply with the provisions of the indenture described above under “—Certain Covenants” and under “—Merger or Consolidation” with respect to the outstanding debt securities of any series (and, if so specified, any other obligation or restrictive covenant added for the benefit of the holders of such series of debt securities), in either case, if we satisfy each of the following conditions:

16

Notwithstanding the foregoing, if we exercise our option under clause (ii) above and an Event of Default with respect to such series of debt securities under the provisions of the indenture relating to certain events of bankruptcy or insolvency or event which, with notice or lapse of time or both, would become an Event of Default with respect to such series of debt securities under such bankruptcy or insolvency provisions shall have occurred and be continuing on the 91st day after the date of such deposit, our obligation to comply with the provisions of the indenture described above under “—Certain Covenants” and under “—Merger or Consolidation” with respect to those debt securities will be reinstated.

Conversion Rights

We will describe in the applicable prospectus supplement the particular terms and conditions, if any, on which debt securities may be convertible into shares of our common stock. These terms will include the conversion price, the conversion period, provisions as to whether conversion will be at our option or the option of the holder, events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of the debt securities.

The Trustee Under the Indenture

We maintain ordinary banking relationships and, from time to time, obtain credit facilities and lines of credit with a number of banks, including the trustee, Wells Fargo Bank, National Association.

Book-Entry, Delivery and Form

We may issue the debt securities of a series in whole or in part in global form that we will deposit with, or on behalf of, a depositary identified in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. We will make payments of principal of, and premium, if any, and interest on debt securities represented by a global security to the trustee and then by the trustee to the depositary.

We anticipate that any global securities will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), New York, New York, and will be registered in the name of DTC’s nominee, and that the following provisions will apply to the depositary arrangements with respect to any global securities. We will describe additional or differing terms of the depositary arrangements in the prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

17

Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the debt securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the debt securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the indenture. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the debt securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form and will not be considered the owners or holders of the debt securities under the indenture. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the indenture. The laws of some states may require that some purchasers of securities take physical delivery of those securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global security.

To facilitate subsequent transfers, all debt securities deposited by participants with DTC are registered in the name of DTC’s nominee, Cede & Co. The deposit of the debt securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

We will make payments due on the debt securities to Cede & Co., as nominee of DTC, in immediately available funds. DTC’s practice upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, is to immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. Payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants. Payment to Cede & Co. is our responsibility. Disbursement of such payments to direct participants is the responsibility of Cede & Co. Disbursement of such payments to the beneficial owners is the responsibility of direct and indirect participants.

Neither we nor the trustee nor any other agent of ours or any agent of the trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that DTC will take any action permitted to be taken by a holder of securities (including the presentation of securities for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in a global security are credited and only in respect of such portion of the aggregate principal amount of the securities as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the debt securities, DTC will exchange each global security for definitive securities, which it will distribute to its participants.

18

If the depositary for any of the debt securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by the obligor within 90 days, the obligor will issue debt securities in definitive form in exchange for the registered global security that had been held by the depositary. Any debt securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the trustee or other relevant agent of the obligor or trustee. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary. In addition, we may at any time determine that the debt securities of any series shall no longer be represented by a global security and will issue securities in definitive form in exchange for such global security pursuant to the procedure described above.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions, such as transfers and pledges, among its participants in such securities through electronic computerized 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 (including the initial purchasers), banks, trust companies, clearing corporations and certain other organizations, some of whom own DTC. 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, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

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