This prospectus supplement, the accompanying prospectus and documents that are incorporated by reference in this prospectus supplement and the accompanying prospectus include forward-looking statements within the meaning of the federal securities laws. In addition, we, or our executive officers on our behalf, may from time to time make forward-looking statements in reports and other documents we file with the SEC or in oral statements made to the press, potential investors or others. All statements that are not historical facts are “forward-looking statements.” The words “estimate,” “project,” “intend,” “expect,” “should,” “will,” “plan,” “believe,” “anticipate,” and similar expressions identify forward-looking statements. These forward-looking statements include statements regarding our expected financial position, business, financing plans, business strategy, business prospects, revenues, working capital, liquidity, capital needs, credit ratings, interest costs and income, in each case relating to our company as a whole, as well as statements regarding acquisitions, potential acquisitions and the benefits of acquisitions.

Forward-looking statements are estimates and projections reflecting our best judgment and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. These statements are based on our management’s beliefs and assumptions, which in turn are based on currently available information. Examples of forward-looking statements in this prospectus supplement include but are not limited to our expectations regarding our ability to generate operating cash flows and reduce debt and associated interest expense and our expectations regarding growth through acquisitions. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products, the cost, timing and success of product upgrades and new product introductions, raw materials costs, expected pricing levels, the timing and cost of expected capital expenditures, expected outcomes of pending litigation, competitive conditions, general economic conditions and expected synergies relating to acquisitions, joint ventures and alliances. These assumptions could prove inaccurate. Although we believe that the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in the section entitled “Risk Factors” in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, incorporated by reference herein. You should understand that the following important factors, in addition to those discussed in the incorporated documents, could affect our future results, and could cause those results or other outcomes to differ materially from those expressed or implied in the forward-looking statements:

We believe these forward-looking statements are reasonable; however, you should not place undue reliance on any forward-looking statements, which are based on current expectations. Further, forward-looking statements speak only as of the date they are made, and we undertake no obligation to publicly update any of these statements in light of new information or future events.

Recent Developments

Senior Unsecured Credit Facility. On July 7, 2008, we entered into a new unsecured credit facility with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders, which replaces our amended and restated secured credit facility, dated as of December 13, 2004. The new facility comprises (i) a two year $350.0 million term loan facility and (ii) a five year $750.0 million revolving credit facility, which includes availability of up to $150.0 million for letters of credit and $25.0 million for swingline loans and of which $50.0 million will be available under a multicurrency subfacility in dollars and other currencies. We may also, subject to compliance with specified conditions, request additional term loans or revolving credit commitments in an aggregate amount not to exceed $350.0 million.

We and specified foreign subsidiaries of ours are borrowers under the revolving credit facility. We have guaranteed the payment and performance by the foreign subsidiary borrowers under the facility.

Amounts outstanding under the new facility may be accelerated upon the occurrence of customary events of default. We also are subject to financial covenants that require us to limit our consolidated total leverage ratio and to maintain a consolidated interest coverage ratio.

Our principal executive offices are located at 6901 Professional Parkway East, Suite 200, Sarasota, Florida 34240, and the telephone number is (941) 556-2601.

In considering whether to purchase the Notes, you should carefully consider all the information we have included or incorporated by reference in this prospectus supplement and the accompanying prospectus. In particular, you should carefully consider the risk factors described below and the risk factors incorporated by reference from our Annual Report on Form 10-K for the year ended December 31, 2007.

The Notes are structurally subordinated to any future indebtedness and to the other liabilities of our subsidiaries.

The Notes are our obligations exclusively and are not the obligations of any of our subsidiaries. Substantially all of our operations are conducted through our subsidiaries. As a result, our cash flow and ability to service our debt, including the Notes, depend upon the earnings of our subsidiaries and the ability of our subsidiaries to distribute to us their earnings, loans or other payments. 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. Except to the extent we are a creditor with separately recognized claims against our subsidiaries, all claims of creditors of our subsidiaries, including trade creditors, and holders of preferred stock, if any, will have priority with respect to the assets of such subsidiaries over our claims (and therefore the claims of our creditors, including holders of the Notes), and our subsidiaries may enter into future borrowing arrangements that limit their ability to transfer funds to us. Consequently, your Notes will be structurally subordinated to all liabilities, including trade payables, of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish. As of June 30, 2008, our subsidiaries had $7.1 million of liabilities. In addition, the indenture governing the Notes permits our subsidiaries to incur additional indebtedness, and does not contain any limitation on the amount of other liabilities, such as trade payables, that may be incurred by our subsidiaries. Thus, the amount of these liabilities may increase in the future.

The Notes will be subject to the prior claims of any future secured creditors.

The Notes are unsecured obligations, ranking effectively junior to our outstanding secured indebtedness and any additional secured indebtedness we may incur. The indenture governing the Notes does not limit the amount of additional debt that we and our subsidiaries may incur, permits us to incur secured debt under specified circumstances and permits our subsidiaries to incur secured debt without restriction. If we incur additional secured debt, our assets securing any such indebtedness will be subject to prior claims by our secured creditors. In the event of our bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding up, or upon any acceleration of the Notes, our assets that secure other indebtedness will be available to pay obligations on the Notes only after all other such debt secured by those assets has been repaid in full. Any remaining assets will be available to you ratably with all of our other unsecured and unsubordinated creditors, including trade creditors. If there are not sufficient assets remaining to pay all these creditors, then all or a portion of the Notes then outstanding would remain unpaid.

The negative covenants in the indenture that governs the Notes provide limited protection to holders of the Notes.

The indenture governing the Notes contains covenants limiting our ability to create certain liens, enter into certain sale and leaseback transactions, and consolidate or merge with, or convey, transfer or lease all or substantially all our assets to, another person. The covenants addressing limitations on liens and on sale and leaseback transactions do not apply to our subsidiaries and contain exceptions that will allow us to incur liens with respect to material assets. See “Description of Debt Securities—Certain Covenants” in the accompanying prospectus. In light of these exceptions, your Notes may be structurally or effectively subordinated to new lenders. The indenture does not limit the amount of additional debt that we or our subsidiaries may incur.

We entered into a new credit agreement dated July 7, 2008 that contains certain covenants restricting our operations and the operations of our subsidiaries. For example, the agreement contains covenants placing certain limits on permitted indebtedness of our subsidiaries and on the creation, incurrence, assumption or existence of certain liens on our property or the property of our subsidiaries. If any of these restrictions were to materially impair the operations and earnings of our subsidiaries their cash distributions to us may be diminished.

We may incur additional indebtedness in the future, which may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes as a result of additional interest payment expenses, a loss in the trading value of your Notes and a risk that the credit rating of your Notes may be lowered.

The provisions of the Notes will not necessarily protect you in the event of certain highly leveraged transactions.

Upon the occurrence of a Change of Control Triggering Event you will have the right to require us to repurchase the Notes as provided in the indenture governing, and on the terms set forth in, the Notes. However, the Change of Control Triggering Event provisions will not afford you protection in the event of certain highly leveraged transactions that may adversely affect you. For example, any leveraged recapitalization, refinancing, restructuring or acquisition initiated by us generally will not constitute a Change of Control that would potentially lead to a Change of Control Triggering Event. As a result, we could enter into any such transaction even though the transaction could increase the total amount of our outstanding indebtedness, adversely affect our capital structure or credit rating or otherwise adversely affect the holders of the Notes. These transactions may not involve a change in voting power or beneficial ownership or result in a downgrade in the ratings of the Notes, or, even if they do, may not necessarily constitute a Change of Control Triggering Event that affords you the protections described in this prospectus supplement. If any such transaction were to occur, the value of your Notes could decline.

We may not be able to repurchase all of the Notes upon a Change of Control Triggering Event, which would result in a default under the Notes.

We will be required to offer to repurchase the Notes upon the occurrence of a Change of Control Triggering Event as provided in the indenture governing the Notes. However, we may not have sufficient funds to repurchase the Notes in cash at such time. 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, which agreements may provide that a Change of Control Triggering Event constitutes an event of default or prepayment under such other indebtedness. Our failure to make such a repurchase would result in a default under your Notes.

Changes in our credit ratings may adversely affect the value of the Notes.

The Notes are rated Baa3 by Moody’s Investors Service, Inc. and BBB- by Standard & Poor’s Ratings Services, in each case with a stable outlook. 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 ratings are not recommendations to buy, sell or hold securities, and there can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Each rating should be evaluated independently of any other rating. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value of your Notes and increase our corporate borrowing costs.

There is no existing market for the Notes, and we do not intend to apply for listing of the Notes on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that a trading market for the Notes will ever develop or will 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 but not limited to prevailing interest rates, our financial condition and results of operations, prospects for companies in our industry generally, 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:

We hereby incorporate by reference risk factors in section Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2007.

We intend to use the net proceeds from the sale of securities issued pursuant to this prospectus supplement to repay outstanding amounts borrowed under a new revolving credit facility, pursuant to a credit agreement, dated July 7, 2008 by and among us, several of our subsidiaries and the lenders party thereto (including affiliates of Banc of America Securities LLC, J.P. Morgan Securities Inc. and Wachovia Capital Markets, LLC) and JPMorgan Chase Bank, N.A. as administrative agent for such lenders. We used these borrowings to refinance the indebtedness outstanding prior to entering into the credit agreement, which was used to finance acquisitions and to fund working capital requirements. The term loan under the credit agreement will mature on July 7, 2010 and the revolving facility will mature on July 7, 2013. The applicable interest rate on the revolving facility to be repaid will be determined in accordance with Section 2.15(a) of the credit agreement, and is currently the eurocurrency rate under the facility plus 1.30%.

The following table sets forth a summary of our consolidated capitalization as of June 30, 2008 on an actual basis, on an as adjusted basis to reflect our new credit facility and as further adjusted to reflect the offering of the Notes by this prospectus supplement. Our consolidated capitalization, as so adjusted to reflect this offering, gives effect to the issuance of the Notes offered by this prospectus supplement and the application of net proceeds therefrom.

The following table sets forth our actual and pro forma ratios of earnings to fixed charges for each of the periods indicated. The pro forma ratios of earnings to fixed charges include the same items as our actual ratios of earnings to fixed charges, and assume that we had applied the net proceeds from this offering to repay outstanding amounts under our new unsecured credit facility as if such facility had been in effect, and this offering had occurred, as of January 1, 2007.

For purposes of calculating the ratios of earnings to fixed charges, earnings is the amount resulting from adding (a) earnings from continuing operations before income taxes and (b) fixed charges. Fixed charges for these purposes include (a) interest expense, (b) amortization of debt issuance costs, and (c) one-third of rental expense, which we consider to be a reasonable approximation of the interest factor included in rental expense. The estimated increase in net interest expense included in the pro forma ratios of earnings to fixed charges for the six months ended June 30, 2008 and 2007 and the year ended December 31, 2007 is $8.2 million, $5.1 million and $9.8 million, respectively.

On July 7, 2008, we entered into a new unsecured credit facility with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders, which replaces our amended and restated secured credit facility, dated as of December 13, 2004. The new facility comprises (i) a two year $350.0 million term loan facility and (ii) a five year $750.0 million revolving credit facility, which includes availability of up to $150.0 million for letters of credit and $25.0 million for swingline loans and of which $50.0 million will be available under a multicurrency subfacility in dollars and other currencies. We may also, subject to compliance with specified conditions, request additional term loans or revolving credit commitments in an aggregate amount not to exceed $350.0 million.

We and specified foreign subsidiaries of ours are borrowers under the revolving credit facility. We have guaranteed the payment and performance by the foreign subsidiary borrowers under the facility.

Borrowings under the term loan and revolving credit facilities will bear interest, at our option, at a rate based on either:

Outstanding letters of credit issued under the facility will be charged a quarterly fee depending on our senior unsecured long-term debt rating. Based on our current rating, the quarterly fee would be payable at a rate of 1.30% per annum, plus a fronting fee of 0.125% per annum on the outstanding amount of all letters of credit.

Additionally, we will pay a quarterly facility fee on the used and unused portions of the revolving credit facility depending on the Company’s senior unsecured long-term debt rating. Based on our current rating, the quarterly fee would accrue at a rate of 0.20% per annum.

In December 2003, we issued $230 million of senior subordinated convertible notes at an original issue discount of 60.498%, resulting in an effective yield of 3.75% per year to maturity. Interest on the notes is payable semiannually, beginning July 15, 2004, until January 15, 2009. After that date, we will not pay cash interest on the notes prior to maturity unless contingent cash interest becomes payable. Instead, after January 15, 2009, interest will be recognized at the effective rate of 3.75% and will represent accrual of original issue discount, excluding any contingent cash interest that may become payable. We will pay contingent cash interest to the holders of the notes during any six month period commencing after January 15, 2009 if the average trading price

of a note for a five trading day measurement period preceding the applicable six month period equals 120% or more of the sum of the issue price, accrued original issue discount and accrued cash interest, if any, for such note. The contingent cash interest payable per note in respect of any six month period will equal the annual rate of 0.25%.

The notes are unsecured senior subordinated obligations, rank junior to our existing and future senior secured indebtedness and rank equally with our existing and future senior subordinated indebtedness.

As originally issued, each $1,000 principal amount of the notes will be convertible at the option of the holder into 12.422 shares of our common stock (giving effect to the 2-for-1 stock split effective August 26, 2005 and subject to further adjustment), if (i) the sale price of our common stock reaches, or the trading price of the notes falls below, specified thresholds, (ii) if the notes are called for redemption or (iii) if specified corporate transactions have occurred. Upon conversion, we would have the right to deliver, in lieu of common stock, cash or a combination of cash and common stock. On November 19, 2004, the Company began a consent solicitation to amend the notes such that the Company would pay the same conversion value upon conversion of the notes, but would change how the conversion value is paid. In lieu of receiving exclusively shares of common stock or cash upon conversion, noteholders would receive cash up to the value of the accreted principal amount of the notes converted and, at the Company’s option, any remainder of the conversion value would be paid in cash or shares of common stock. The consent solicitation was successfully completed on December 6, 2004 and the amended conversion provisions were adopted.

Holders may require us to purchase all or a portion of their notes on January 15, 2009, January 15, 2014, January 15, 2019, January 15, 2024, and January 15, 2029, at stated prices plus accrued cash interest, if any, including contingent cash interest, if any. We may only pay the purchase price of such notes in cash and not in common stock.

We may redeem for cash all or a portion of the notes at any time on or after January 15, 2009 at redemption prices equal to the sum of the issue price plus accrued original issue discount and accrued cash interest, if any, including contingent cash interest, if any, on such notes to the applicable redemption date.

As of September 30, 2005, the senior subordinated convertible notes were reclassified from long term to short term debt as the notes became convertible on October 1, 2005 based upon the Company’s common stock trading above the trigger price for at least 20 trading days during the 30 consecutive trading-day period ending on September 30, 2005.

For purposes of this section, references to “we,” “us” and “our” are references to Roper Industries, Inc. only and not to any of its subsidiaries. We will issue the Notes under an indenture to be dated as of August 4, 2008 (the “Indenture”) between us and Wells Fargo Bank, N.A., as trustee (the “Trustee”).

The following is a summary of the material provisions of the Indenture. It does not include all of the provisions of the Indenture. We urge you to read the Indenture because it defines your rights. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”). A copy of the Indenture may be obtained from us. You can find definitions of certain capitalized terms relating to the Notes as used in the Indenture in this description and in the accompanying prospectus under “Description of Debt Securities—Certain Definitions”. The following summary supplements the description of the general terms and provisions of the debt securities set forth under “Description of Debt Securities” beginning on page 7 of the accompanying prospectus.

We will issue the Notes in fully registered form in minimum denominations of $2,000 and multiples of $1,000 in excess thereof. The Trustee will initially act as Paying Agent and Registrar for the Notes. The Notes may be presented for registration of transfer and exchange at the offices of the Registrar. We may change any Paying Agent and Registrar without notice to holders of the Notes (the “Holders”). We will pay principal (and premium, if any) on the Notes at the Trustee’s corporate office in New York, New York. At our option, interest may be paid at the Trustee’s corporate trust office or by check mailed to the registered address of Holders.

The Notes will not be guaranteed by any of our subsidiaries. The Notes will not be entitled to the benefit of any mandatory sinking fund.

We will issue $500,000,000 aggregate principal amount of the Notes in this offering. The Notes will mature on August 15, 2013. Interest on the Notes will accrue at the rate of 6.625% per year. Interest on the Notes will be payable semi-annually in arrears on each February 15 and August 15, commencing on February 15, 2009, to the persons who are registered Holders at the close of business on the February 1 and August 1, whether or not a business day, immediately preceding the applicable interest payment date.

Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the issue date. If any interest payment date, Redemption Date (as defined below), repurchase date or maturity date falls on a day which is not a business day, payment of interest, principal and premium, if any, with respect to such Notes will be made on the next business day with the same force and effect as if made on the due date and no interest on such payment will accrue from and after such due date. Interest will be computed on the basis of a 360-day year composed of twelve 30-day months.

We may from time to time without notice to, or the consent of, any Holder, create and issue additional notes under the Indenture, equal in rank to the Notes offered hereby in all respects (or in all respects except for the payment of interest accruing prior to the issue date of such additional notes, or except for the first payment of interest following the issue date of such additional notes) so that the additional notes may be consolidated and form a single series with the Notes offered hereby, and have the same terms as to status, redemption and otherwise as the Notes offered hereby.

We will pay interest (including post-petition interest in any proceeding under any bankruptcy law) on overdue payments of the principal, purchase price and redemption price of the Notes from time to time on demand at the rate then borne by the Notes offered hereby; and will pay interest (including post-petition interest in any proceeding under any bankruptcy law) on overdue installments of interest, if any (without regard to any applicable grace periods) on the Notes offered hereby from time to time on demand at the same rate to the extent lawful.

As of June 30, 2008, on a pro forma basis after giving effect to our new credit facility and this offering and the use of proceeds therefrom as described under “Use of Proceeds,” the Notes would have been effectively subordinated to approximately $7.1 million of obligations of our subsidiaries.

The interest rate payable on the Notes will be subject to adjustments from time to time if Moody’s Investors Service, Inc. (“Moody’s”) or Standard & Poor’s Rating Services, a division of the McGraw-Hill Companies, Inc. (“S&P”), including their respective successors, as applicable, (or, if applicable, any Substitute Rating Agency (as defined below)) downgrades (or subsequently upgrades) the rating assigned to the Notes, as set forth below.

If the ratings from Moody’s or S&P (or, in either case if applicable, any Substitute Rating Agency) with respect to the Notes (each an “Interest Rate Rating Agency,” and collectively, the “Interest Rate Rating Agencies”) is decreased to a rating set forth in the following table with respect to that Interest Rate Rating Agency, the per annum interest rate on the 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 Notes has been adjusted upward as a result of a decrease in a rating by an Interest Rate Rating Agency and that Interest Rate Rating Agency subsequently increases its rating on the Notes to any of the threshold ratings set forth above, the per annum interest rate on the Notes will be decreased such that the per annum interest rate equals the interest rate set forth on the cover page of this prospectus supplement 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 on the 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 on the Notes to “BBB-” (or its equivalent if with respect to any Substitute Rating Agency) or higher, the per annum interest rate on the Notes will be decreased to the interest rate set forth on the cover page of this prospectus supplement.

No adjustment in the interest rate on the Notes shall be made solely as a result of an Interest Rate Rating Agency ceasing to provide a rating. If at any time less than two Interest Rate Rating Agencies provide a rating on the Notes, we will use commercially reasonable efforts to obtain a rating on the Notes from another “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, to the extent one exists, and if another nationally recognized statistical rating organization rates the 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 Notes pursuant to the table above, (1) such Substitute Rating Agency will be substituted for the last Interest Rate Rating Agency to provide a rating on the Notes but which has since ceased to provide such rating, (2) 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 (3) the per annum interest rate on the Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate set forth on the cover page of this prospectus supplement 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 (2) above). For so long as (a) only one Interest Rate Rating Agency provides a rating on the Notes, any increase or decrease in the interest rate on the Notes necessitated by a reduction or increase in the rating by that Interest Rate Rating Agency shall be twice the applicable percentage set forth in the table above and (b) no Interest Rate Rating Agency provides a rating on the Notes, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% above the interest rate set forth on the cover page of this prospectus supplement. If Moody’s or S&P ceases to rate the Notes or make a rating of the Notes publicly available for reasons within our control, we will not be entitled to obtain a rating from a Substitute Rating Agency and the increase or decrease in the per annum interest rate on the Notes shall be determined in the manner described above as if either only one or no Rating Agency provides a rating on the Notes, as the case may be.

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 Notes be reduced below the interest rate set forth on the cover page of this prospectus supplement or (2) the per annum interest rate on the Notes exceed 2.00% above the interest rate set forth on the cover page of this prospectus supplement.

Any interest rate increase or decrease described above will take effect on the next business day after the rating change has occurred.

The interest rates on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any Rating Agency) if the Notes become rated “Baa1” (or its equivalent) or higher by Moody’s (or any Substitute Rating Agency) and “BBB+” (or its equivalent) or higher by S&P (or any Substitute Rating Agency), or one of those ratings if rated by only one Interest Rate Rating Agency, in each case with a stable or positive outlook.

The Notes will be redeemable, in whole or in part, at our option, at any time or from time to time prior to maturity on at least 30 days’, but not more than 60 days’, prior notice mailed to the registered address of each Holder of the Notes (the “Redemption Date”). The redemption price will be equal to the greater of:

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolation (on a day count basis) of the interpolated 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.

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

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers, appointed by the Trustee after consultation with us.

“Reference Treasury Dealer” means Banc of America Securities LLC, J.P. Morgan Securities Inc. or one other Primary Treasury Dealer selected by Wachovia Capital Markets, LLC and their respective affiliates, and their respective successors and one other nationally recognized investment banking firm that is a primary U.S. government securities dealer in the City of New York (a “Primary Treasury Dealer”) as selected by us. If any of the foregoing or their affiliates shall cease to be a Primary Treasury Dealer, we will substitute therefor another Primary Treasury Dealer.

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

“Remaining Scheduled Payments” means, with respect to each Note to be redeemed, the remaining scheduled payments of principal of and interest on the Note that would be due after the related Redemption Date but for the redemption. If that Redemption Date is not an interest payment date with respect to a Note, the amount of the next succeeding scheduled interest payment on the Note will be reduced by the amount of interest accrued on the Note to the Redemption Date.

On and after the Redemption Date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption, unless we default in the payment of the redemption price and accrued interest. On or before the Redemption Date, we 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.

In the event that we choose to redeem less than all of the Notes, selection of the Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed; or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate.

No Notes of a principal amount of $2,000 or less shall be redeemed in part. Notice of redemption will be mailed by first-class mail at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption as long as we have deposited with the Paying Agent funds in satisfaction of the applicable redemption price.

If a Change of Control Triggering Event (as defined below) occurs, unless we have exercised our right to redeem the Notes as described above, we will be required to make an offer to repurchase all or, at the Holder’s option, any part (equal to $2,000 or any multiple of $1,000 in excess thereof), of each Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the Notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased, to, but not including, the date of purchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event, we will be required to mail a notice to Holders of the Notes, with a copy to the Trustee for the Notes, describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. We must comply with the requirements of applicable securities laws and regulations in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event.

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

The Paying Agent will be required to promptly mail, to each Holder who properly tendered Notes, the purchase price for such Notes, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or a multiple of $1,000 in excess thereof.

We will not be required to make a Change of Control Offer upon 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 such third party purchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, we will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

We will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provision of any such securities laws or regulations conflicts with the Change of Control Offer provisions of the Notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict. For purposes of the repurchase provisions of the Notes, the following terms will be applicable:

“Change of Control” means the occurrence of any one of the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of our properties or assets and those of our subsidiaries, taken as a whole, to one or more persons, other than to us or one of our subsidiaries; (2) the first day on which a majority of the members of our board of directors is not composed of Continuing

Directors (as defined below); (3) the consummation of any transaction including, without limitation, any merger, amalgamation, arrangement or consolidation the result of which is that any person becomes the beneficial owner, directly or indirectly, of more than 50% of our Voting Stock; (4) 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 the outstanding Voting Stock of us or 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 Voting Stock of the surviving person immediately after giving effect to such transaction; or (5) the adoption of a plan relating to our liquidation or dissolution. For the purposes of this definition, “person” and “beneficial owner” have the meanings used in Section 13(d) of the Exchange Act.

“Change of Control Triggering Event” means the Notes cease to be rated Investment Grade by both Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement of the Change of Control or our intention to effect a Change of Control and ending 60 days following consummation of such Change of Control, which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change. Unless at least one Rating Agency is providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Continuing Directors” means, as of any date of determination, any member of our board of directors who (1) was a member of our board of directors on the Issue Date; or (2) was nominated for election, elected or appointed to our board of directors with the approval of a majority of the Continuing Directors who were members of our board of directors at the time of such nomination, election or appointment (either by a specific vote or by approval by such directors of our proxy statement in which such member was named as a nominee for election as a director).

“Investment Grade” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s or BBB- (or the equivalent) by S&P, 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., a subsidiary of Moody’s Corporation, and its successors.

“Rating Agencies” means (a) each of Moody’s and S&P; and (b) if any of the Rating Agencies ceases to provide rating services to issuers or investors, and no Change of Control Triggering Event has occurred or is occurring, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act that is selected by us (as certified by a resolution of our board of directors) as a replacement for Moody’s or S&P, or both of them, as the case may be, and that is reasonably acceptable to the Trustee.

“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 of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The 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. 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. Except in the limited circumstances described below, 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 initial purchasers), 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.

Upon the issuance of each global note, DTC will credit, on its book-entry registration and transfer system, the respective principal amount of the individual beneficial interests represented by the global note to the accounts of participants. Ownership of beneficial interests in each global note will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in each global note will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by DTC (with respect to participants’ interests) and such participants (with respect to the owners of beneficial interests in the global note other than participants).

So long as DTC or its nominee is the registered holder and owner of a global note, DTC or such nominee, as the case may be, will be considered the sole legal owner of the Notes represented by the global note for all purposes under the indenture, the Notes and applicable law. Except as set forth below, owners of beneficial interests in a global note will not be entitled to receive certificated Notes and will not be considered to be the owners or holders of any Notes under the global note. We understand that under existing industry practice, in the event an owner of a beneficial interest in a global note desires to take any actions that DTC, as the holder of the global note, is entitled to take, DTC would authorize the participants to take such action, and that participants would authorize beneficial owners owning through such participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them. No beneficial owner of an interest in a global note will be able to transfer the interest except in accordance with DTC’s applicable procedures, in addition to those provided for under the indenture. Because DTC can only act on behalf of participants, who in turn act on behalf of others, the ability of a person having a beneficial interest in a global note to pledge that interest to persons that do not participate in the DTC system, or otherwise to take actions in respect of that interest, may be impaired by the lack of physical certificate of that interest.

All payments on the Notes represented by a global note registered in the name of and held by DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner and holder of the global note.

We expect that DTC or its nominee, upon receipt of any payment of principal, premium, if any, or interest in respect of a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global note as shown on 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 practices as is now the case with securities held for accounts for customers registered in the names of nominees for such customers. These

payments, however, will be the responsibility of such participants and indirect participants, and neither we, the underwriters, the trustee nor any paying agent will have any responsibility or liability for any aspect of the records relating to, or payments made on account of beneficial ownership interests in any global note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and its participants or the relationship between such participants and the owners of beneficial interests in the global note.

Unless and until it is exchanged in whole or in part for certificated Notes, each global note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC. Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds.

We expect that DTC will take any action permitted to be taken by a holder of Notes (including the presentation of Notes for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in a global note are credited and only in respect of such portion of the aggregate principal amount of the Notes as to which such participant or participants has or have given such direction. Although we expect that DTC will agree to the foregoing procedures in order to facilitate transfers of interests in each global note among participants of DTC, DTC is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither we, the underwriters, nor the trustee will have any responsibility for the performance or nonperformance by DTC or their participants or indirect participants of their respective obligations under the rules and procedures governing their operations. Under certain circumstances described in the accompanying prospectus, DTC may exchange the global notes for Notes in certificated form of like tenor and of an equal principal amount, in authorized denominations. These certificated Notes will be registered in such name or names as DTC shall instruct the trustee. It is expected that such instructions may be based upon directions received by DTC from participants with respect to ownership of beneficial interests in global securities. The certificated Notes will be subject to certain restrictions on registration of transfers described under “Transfer Restrictions,” and will bear the legend set forth thereunder.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we do not take responsibility for its accuracy.

The Notes will trade in the same-day funds settlement system of DTC until maturity or until we issue the Notes in certificated form. DTC will therefore require secondary market trading activity in the Notes to settle in immediately available funds. We can give no assurance as to the effect, if any, of settlement in immediately available funds on trading activity in the Notes.

If the depositary for a global security is DTC, you may hold interests in the global notes through Euroclear Bank S.A./N.V., as operator of the Euroclear System, which is referred to as “Euroclear” or Clearstream Banking, société anonyme, which is referred to as “Clearstream, Luxembourg,” in each case, as a participant in DTC.

Euroclear and Clearstream, Luxembourg will hold interests, in each case, on behalf of their participants through customers’ securities accounts in the names of Euroclear and Clearstream, Luxembourg on the books of their respective depositaries, which in turn will hold such interests in customers’ securities in the depositaries’ names on DTC’s books.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the Notes made through Euroclear or Clearstream, Luxembourg must comply with the rules and procedures of those systems. Those

systems could change their rules and procedures at any time. We have no control over those systems or their participants, and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, Luxembourg, on the one hand, and other participants in DTC, on the other hand, would also be subject to DTC’s rules and procedures.

Investors will be able to make and receive through Euroclear and Clearstream, Luxembourg payments, deliveries, transfers, exchanges, notices and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the Notes through these systems and wish, on a particular day, to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream, Luxembourg may need to make special arrangements to finance any purchase or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than transactions within one clearing system.

The following are the material U.S. federal income tax consequences of ownership and disposition of the Notes. This discussion applies only to Notes that are:

This discussion does not describe all of the tax consequences that may be relevant to holders in light of their particular circumstances or to holders subject to special rules, such as:

If an entity that is classified as a partnership for U.S. federal income tax purposes holds Notes, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding Notes and partners in such partnerships are urged to consult their tax advisers as to the particular U.S. federal income tax consequences to them of holding and disposing of the Notes.

This summary is based on the Internal Revenue Code of 1986, as amended to the date hereof (the “Code”), administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein. Persons considering the purchase of Notes are urged to consult their tax advisers with regard to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

As used herein, the term “U.S. Holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

The term “U.S. Holder” also includes certain former citizens and residents of the United States.

It is expected, and therefore this discussion assumes, that the Notes will be issued without original issue discount for U.S. federal income tax purposes. Accordingly, interest paid on a Note will be taxable to a U.S. Holder as ordinary interest income at the time it accrues or is received in accordance with the U.S. Holder’s method of accounting for U.S. federal income tax purposes.

Upon the occurrence of a Change of Control Triggering Event, Roper would generally be required to repurchase the Notes at 101% of their principal amount plus accrued and unpaid interest, as described under “Description of the Notes—Repurchase Upon Change of Control Triggering Event”. Although the issue is not free from doubt, Roper intends to take the position that such requirement does not result in the Notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. Roper’s position is not binding on the Internal Revenue Service (the “IRS”). If the IRS successfully takes a contrary position, U.S. Holders would be required to treat any gain recognized on the sale or other disposition of the Notes as ordinary income rather than as capital gain. Furthermore, U.S. Holders would be required to accrue interest income on a constant yield basis at an assumed yield determined at the time of issuance of the Notes (which is not expected to differ significantly from the interest rate on the Notes), with adjustments to such accruals when any contingent payments are made that differ from the payments calculated based on the assumed yield. U.S. Holders should consult their tax advisers regarding the tax consequences of the Notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the Notes are not treated as contingent payment debt instruments.

Upon the sale, exchange, redemption or other taxable disposition of a Note, a U.S. Holder will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or other taxable disposition and the U.S. Holder’s tax basis in the Note. For these purposes, the amount realized does not include any amount attributable to accrued interest. Amounts attributable to accrued interest are treated as interest as described under “—Payments of Interest” above.

Gain or loss realized on the sale, exchange, redemption or other taxable disposition of a Note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale, exchange, redemption or other taxable disposition the Note has been held for more than one year. The deductibility of capital losses is subject to limitations.

Information returns will be filed with the IRS in connection with payments on the Notes and the proceeds from a sale or other disposition of the Notes, unless the U.S. Holder establishes an exemption from information reporting. A U.S. Holder will be subject to U.S. backup withholding on these payments if the U.S. Holder fails to provide its taxpayer identification number to the paying agent and comply with certain certification procedures or otherwise establish an exemption from backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

As used herein, the term “Non-U.S. Holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

“Non-U.S. Holder” does not include a holder who is an individual present in the United States for 183 days or more in the taxable year of disposition of a Note and who is not otherwise a resident of the United States for U.S. federal income tax purposes. Such a holder is urged to consult his or her own tax adviser regarding the U.S. federal income tax consequences of the sale, exchange, redemption or other taxable disposition of a Note.

Subject to the discussion below concerning backup withholding, payments of principal, interest and premium on the Notes by Roper or any paying agent to any Non-U.S. Holder will not be subject to U.S. federal withholding tax, provided that, in the case of interest:

If payments on the Notes are effectively connected with a Non-U.S. Holder’s trade or business in the United States, payments will be treated in the manner described below under “—Effectively Connected Income”.

Subject to the discussion below concerning backup withholding, a Non-U.S. Holder generally will not be subject to U.S. federal income tax on gain recognized on a sale or other disposition of Notes, unless the gain is effectively connected with the conduct of a trade or business of the Non-U.S. Holder in the United States.

If a Non-U.S. Holder of a Note is engaged in a trade or business in the United States, and if interest on the Note or gain recognized by the Non-U.S. Holder on a sale or other disposition of Note, is effectively connected with the conduct of this trade or business, the Non-U.S. Holder, although exempt from the withholding tax discussed above, will generally be taxed in the same manner as a U.S. Holder (see “—Tax Consequences to U.S. Holders” above), subject to an applicable income tax treaty providing otherwise, except that the holder will be required to provide to Roper a properly executed IRS Form W-8ECI in order to claim an exemption from withholding tax in respect of interest. These holders are urged to consult their own tax advisers with respect to other U.S. tax consequences of the ownership and disposition of Notes including, with respect to corporate holders, the possible imposition of a branch profits tax at a rate of 30% (or a lower treaty rate).

Information returns will be filed with the IRS in connection with payments of interest on the Notes. Unless the Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person, information returns may be filed with the IRS in connection with the proceeds from a sale or other disposition of the Notes and the Non-U.S. Holder may be subject to U.S. backup withholding on payments on the Notes or on the proceeds from a sale or other disposition of the Notes. Compliance with the certification procedures required to claim the exemption from withholding tax on interest described above will satisfy the certification requirements necessary to avoid backup withholding as well. The amount of any backup withholding from a payment to a Non-U.S. Holder will be allowed as a credit against the Non-U.S. Holder’s U.S. federal income tax liability and may entitle the Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

We are offering the Notes described in this prospectus supplement through a number of underwriters. Banc of America Securities LLC, J.P. Morgan Securities Inc. and Wachovia Capital Markets, LLC are the representatives of the underwriters. We have entered into a firm commitment underwriting agreement with the representatives. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, the aggregate principal amount of Notes listed next to its name in the following table:

The underwriting agreement is subject to a number of terms and conditions and provides that the underwriters must buy all of the Notes if they buy any of them. The underwriters will sell the Notes to the public when and if the underwriters buy the Notes from us.

The underwriters have advised us that they propose initially to offer the Notes to the public at the public offering prices set forth on the cover of this prospectus supplement, and to certain dealers at such price less a concession not in excess of 0.350% of the principal amount of the Notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of 0.250% of the principal amount of the Notes to certain other dealers. After the public offering of the Notes, the public offering price and other selling terms may be changed.

We estimate that our share of the total expenses of the offering, excluding the underwriting discount, will be approximately $650,000.

We have agreed to indemnify the underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933.

The Notes are a new issue of securities with no established trading market. The Notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the Notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

We have agreed, during the period from the date of the underwriting agreement until the first business day immediately following the delivery of the Notes, not to offer, sell, contract to sell or otherwise dispose of any debt securities that are substantially similar to the Notes (other than commercial paper issued in the ordinary course of business), without the prior written consent of the underwriters.

In connection with the offering of the Notes, certain of 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, creating a short position. In addition, the underwriters may bid for, and purchase, the Notes in the open market to cover short positions or to stabilize the price of the Notes. Any of these activities may stabilize or maintain the market price of the Notes above independent market levels, but no representation is

made hereby of the magnitude of any effect that the transactions described above may have on the market price of the Notes. The underwriters will not be required to engage in these activities, and may engage in these activities, and may end any of these activities, at any time without notice.

In the ordinary course of business, the underwriters or their affiliates have provided and may in the future provide commercial, financial advisory or investment banking services for us and our subsidiaries for which they have received or will receive customary compensation.

Affiliates of Banc of America Securities LLC, J.P. Morgan Securities Inc. and Wachovia Capital Markets, LLC are lenders under our credit agreement, for which these underwriters and affiliates have been paid customary fees. A portion of our outstanding borrowings under this credit agreement will be repaid with the net proceeds of the sale of the Notes. Because more than 10% of the net proceeds of the offering will be paid to affiliates of Banc of America Securities LLC, J.P. Morgan Securities Inc. or Wachovia Capital Markets, LLC participating in the distribution of the Notes, this offering is being made in compliance with NASD 2710(h). Since the offering is for a class of securities rated investment grade by Standard & Poor’s Rating Services, the appointment of a qualified independent underwriter for the offering pursuant to the NASD conduct rules is not necessary.

We expect that delivery of the Notes will be made against payment therefor on or about the settlement date, which will be the fourth business day following the date of this prospectus supplement. Under Rule 15c6-1 of the Securities and Exchange Commission under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three 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 supplement will be required, by virtue of the fact that the Notes initially will settle in T+4, to specify an alternate settlement cycle 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 hereof should consult their own advisor.

Mitsubishi UFJ Securities International plc is not a U.S. registered broker-dealer and, therefore, to the extent that it intends to effect any sales of the Notes in the United States, it will do so through one or more U.S. registered broker-dealers as permitted by FINRA regulations.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the Relevant Implementation Date) it has not made and will not make an offer of Notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Notes which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of Notes to the public in that Relevant Member State at any time:

For the purposes of this provision, the expression an “offer of Notes to the public” in relation to any Notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe the Notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

Certain legal matters regarding the Notes offered hereby will be passed upon for us by Davis Polk & Wardwell, Menlo Park, California and for the underwriters by Simpson Thacher & Bartlett LLP, New York, New York.

About this Prospectus

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf process, we may sell any combination of the securities described in this prospectus in one or more offerings from time to time. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change

information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information”.

We file annual, quarterly and current reports, proxy statements and other information with the Securities and Exchange Commission (the “SEC”). You may read and copy any document that we file at the Public Reference Room of the SEC at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains an Internet site at http://www.sec.gov, from which interested persons can electronically access the registration statement including the exhibits and schedules thereto.

As permitted by the SEC rules, this prospectus does not contain all the information that you can find in the registration statement or the exhibits to that statement. The SEC allows us to “incorporate by reference” the information we file with them, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is an important part of this prospectus, and information that we file later with the SEC will automatically update and supersede this information. We incorporate by reference the documents listed below, and all filings pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), subsequently filed with the SEC prior to the termination of the offering under this prospectus:

This prospectus and documents that are incorporated by reference in this prospectus include forward-looking statements within the meaning of the federal securities laws. In addition, we, or our executive officers on our behalf, may from time to time make forward-looking statements in reports and other documents we file with the SEC or in oral statements made to the press, potential investors or others. All statements that are not historical facts are “forward-looking statements.” The words “estimate,” “project,” “intend,” “expect,” “should,” “will,” “plan,” “believe,” “anticipate,” and similar expressions identify forward-looking statements. These forward-looking statements include statements regarding our expected financial position, business, financing plans, business strategy, business prospects, revenues, working capital, liquidity, capital needs, interest costs and income, in each case relating to our company as a whole, as well as statements regarding acquisitions, potential acquisitions and the benefits of acquisitions.

debt and associated interest expense and our expectations regarding growth through acquisitions. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products, the cost, timing and success of product upgrades and new product introductions, raw materials costs, expected pricing levels, the timing and cost of expected capital expenditures, expected outcomes of pending litigation, competitive conditions, general economic conditions and expected synergies relating to acquisitions, joint ventures and alliances. These assumptions could prove inaccurate. Although we believe that the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in the section entitled “Risk Factors” in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, incorporated by reference herein. You should understand that the following important factors, in addition to those discussed in the incorporated documents, could affect our future results, and could cause those results or other outcomes to differ materially from those expressed or implied in the forward-looking statements:

We intend to use the net proceeds from the sale of securities issued pursuant to this registration statement for general corporate purposes which may include repaying debt, making capital investments and funding working capital requirements, or financing acquisitions. If we decide to use the net proceeds from a particular offering of securities for a specific purpose, we will describe that purpose and include any other relevant information in the related prospectus supplement.

The following table sets forth our ratios of earnings to fixed charges and to combined fixed charges and preferred stock dividends for each of the periods indicated.

For purposes of calculating these ratios, earnings is the amount resulting from adding (a) earnings from continuing operations before income taxes and (b) fixed charges. Fixed charges for these purposes include (a) interest expense, (b) amortization of debt issuance costs, and (c) one-third of rental expense, which we consider to be a reasonable approximation of the interest factor included in rental expense. Currently, we have no shares of preferred stock outstanding and we have not paid any dividends on preferred stock in the periods presented. Therefore, the ratios of earnings to combined fixed charges and preferred stock dividends are not different from the ratios of earnings to fixed charges.

Our authorized capital stock consists of 350,000,000 shares of common stock, par value $0.01 per share, and 1,000,000 shares of preferred stock, par value $0.01 per share.

The following descriptions are summaries of the material terms of our amended and restated certificate of incorporation and amended and restated by-laws. Reference is made to the more detailed provisions of, and the descriptions are qualified in their entirety by reference to, our amended and restated certificate of incorporation and amended and restated by-laws, copies of which are filed with the SEC.

As of July 18, 2008, there were 89,610,237 shares of our common stock outstanding.

Voting. Each holder of shares of our common stock is entitled to one vote on each matter properly submitted to a vote of our stockholders.

Dividend Rights. Holders of common stock may receive dividends when declared by our board of directors out of our funds that we can legally use to pay dividends. We may pay dividends in cash, stock or other property. In certain cases, holders of common stock may not receive dividends until we have satisfied our obligations to holders of any outstanding preferred stock.

Other Rights. If we voluntarily or involuntarily liquidate, dissolve or wind up our business, holders of common stock will receive any remaining assets on a pro rata basis after we have provided for any liquidation preference for any outstanding shares of preferred stock. When we issue securities in the future, holders of common stock will not have preemptive rights to buy any portion of those issued securities.

Listing. Our common stock is listed on the New York Stock Exchange under the symbol “ROP.” The transfer agent and registrar for the common stock is Wachovia Bank, N.A., Charlotte, North Carolina.

Fully Paid. All of our outstanding shares of common stock are fully paid and nonassessable, which means that the full purchase price for the outstanding shares of common stock has been paid and the holders of such shares will not be assessed any additional monies for such shares. Any additional common stock that we may issue in the future pursuant to an offering under this prospectus will also be fully paid and nonassessable.

Under our amended and restated certificate of incorporation, without further stockholder action, our board of directors is authorized, subject to any limitations prescribed by the law of the State of Delaware, to provide for the issuance of the shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereof, and to increase or decrease the number of shares of any such series (but not below the number of shares of such series then outstanding).

General. Certain provisions of our amended and restated certificate of incorporation, amended and restated by-laws and applicable law may make it less likely that our management would be changed or someone would acquire our company without the consent of our board of directors. These provisions may delay, deter or prevent tender offers or takeover attempts that stockholders may believe are in their best interests, including tender offers or takeover attempts that might allow stockholders to receive a premium over the market price of their common stock.

Preferred Stock. Under our amended and restated certificate of incorporation, our board of directors can at any time, and without stockholder approval, issue one or more new series of preferred stock. In some cases, the issuance of preferred stock without stockholder approval could discourage or make more difficult attempts to take control of our company through a merger, tender offer, proxy contest or otherwise. Preferred stock with special voting rights or other features issued to persons favoring our management could stop a takeover by preventing the person trying to take control of our company from acquiring enough shares necessary to take control.

Proposal and Nominating Procedures. Stockholders can propose that business be considered at an annual meeting of stockholders, and, in addition to our board of directors, can nominate candidates for our board of directors. However, a stockholder must follow the advance notice procedures described in Section 8 of our amended and restated by-laws. In general, a stockholder must submit a written notice of the proposal and the stockholder’s interest in the proposal, or of the nomination, to our corporate secretary at least 90 days and at most 120 days before the first anniversary date of the annual meeting for the preceding year.

Removal of Directors. Subject to the rights of holders of any outstanding series of preferred stock, any director may be removed from office at any time, but only for cause, and only by an affirmative vote of the holders of at least a majority of the voting power of all shares entitled to vote for the election of directors.

Amendment of By-laws. Under our amended and restated certificate of incorporation and amended and restated by-laws, our board of directors can adopt, amend or repeal the by-laws by a majority vote of the directors then in office. Our stockholders also have the power to amend or repeal our amended and restated by-laws at any meeting at which a quorum is present by a vote of two-thirds of the number of shares of stock present and entitled to vote.

Business Combination Statute. We are subject to Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in various “business combination” transactions with any interested stockholder for a period of three years following the date of the transactions in which the person became an interested stockholder, unless:

A “business combination” is defined to include mergers, asset sales, and other transactions resulting in financial benefit to a stockholder. In general, an “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years, did own) 15% or more of a corporation’s voting stock. The statute could prohibit or delay mergers or other takeover or change in control attempts with respect to our company and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

This prospectus describes certain general terms and provisions of the debt securities. The debt securities will be issued under an indenture (the “Indenture”) between Roper Industries, Inc. and Wells Fargo Bank, N.A., as trustee (the “Trustee”), in one or more series established from time to time in or pursuant to a board resolution and set forth in an officer’s certificate or supplemental indenture. When we offer to sell a particular series of debt securities, we will describe the specific terms for the securities in a supplement to this prospectus. The prospectus supplement will also indicate whether the general terms and provisions described in this prospectus apply to a particular series of debt securities.

The Indenture will not limit the amount of debt securities which we may issue. We have the right to “reopen” a previous issue of a series of debt securities by issuing additional debt securities of such series. We may issue debt securities up to an aggregate principal amount as we may authorize from time to time. The debt securities will be our unsecured obligations and will rank equally with all of our other unsecured and unsubordinated debt from time to time outstanding. Our secured debt, if any, will be effectively senior to the debt securities to the extent of the value of the assets securing such debt. The debt securities will be exclusively our obligations and not of our subsidiaries and therefore the debt securities will be structurally subordinate to the debt and liabilities of any of our subsidiaries. The prospectus supplement will describe the terms of any debt securities being offered, including:

With respect to each series of debt securities, we will not issue, incur, create, assume or guarantee any Indebtedness secured by a Lien upon any Principal Property or upon any of the Capital Stock or Indebtedness of any of our Significant Subsidiaries (whether such Principal Property, or Capital Stock or Indebtedness is now existing or owed or is hereafter created or acquired) without in any such case effectively providing, concurrently with the issuance, incurrence, creation, assumption or guaranty of any such secured Indebtedness, or the grant of such Lien, that the debt securities of the applicable series (together, if we shall so determine, with any other Indebtedness of or guarantee by us ranking equally with the debt securities) shall be secured equally and ratably with (or, at our option, prior to) such secured Indebtedness. The foregoing restriction, however, will not apply to any of the following:

Notwithstanding the restrictions in the preceding paragraph, we will be permitted to incur Indebtedness, secured by Liens otherwise prohibited by this covenant, which, together with the value of Attributable Debt outstanding pursuant to the second paragraph of the “—Limitation on Sale and Lease-Back Transactions” covenant below, do not exceed 15% of Consolidated Net Tangible Assets measured at the date of incurrence of the Lien.

We will not enter into any Sale and Lease-Back Transaction with respect to any Principal Property, other than any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or any such Sale and Lease-Back Transaction between us and one of our Subsidiaries or between our Subsidiaries, unless: we or such Subsidiary would be entitled to incur Indebtedness secured by a Lien on the Principal Property involved in such Sale and Lease-Back Transaction at least equal in amount to the Attributable Debt with respect to such Sale and Lease-Back Transaction, without equally and ratably securing the debt securities, pursuant to the covenant described above under the caption “—Limitation on Liens”; or (b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as determined in good faith by our board of directors) and we apply an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a combination) of (i) the prepayment or retirement of the debt securities, (ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of other Indebtedness of us or of one of our Subsidiaries (other than Indebtedness that is subordinated to the debt securities or Indebtedness owed to us or one of our Subsidiaries) that matures more than 12 months after its creation or (iii) the purchase, construction, development, expansion or improvement of other comparable property.

Notwithstanding the restrictions in the preceding paragraph, we will be permitted to enter into Sale and Lease-Back Transactions otherwise prohibited by this covenant, which, together with all Indebtedness outstanding pursuant to the second paragraph of the “—Limitation on Liens” covenant above, do not exceed 15% of Consolidated Net Tangible Assets measured at the closing date of the Sale and Lease-Back Transaction.

We may not merge or consolidate with any other person or persons (whether or not affiliated with us), and we may not sell, convey, transfer, lease or otherwise dispose of all or substantially all of our property or assets to any other person or persons (whether or not affiliated with us), unless the following conditions are satisfied:

The restrictions in the second and third bullets above shall not be applicable to:

In the case of any such consolidation, merger, sale, transfer or other conveyance, but not a lease, in a transaction in which there is a successor entity, the successor entity will succeed to, and be substituted for, us under the Indenture and, subject to the terms of the Indenture, we will be released from the obligation to pay principal and interest on the debt securities and all obligations under the Indenture.

For purposes of the foregoing, if we consummate a Holding Company Reorganization, the newly formed holding company (“New HoldCo”) shall be treated as the “successor person” and the Holding Company Reorganization shall constitute the transfer to New HoldCo of substantially all of our assets.

The Indenture for the debt securities provides that upon completion of the Holding Company Reorganization, Roper will be discharged from all obligations and covenants under the Indenture and the Notes and New HoldCo will be the sole obligor on the debt securities.

“Holding Company Reorganization” shall mean a merger with and into a newly formed wholly-owned, indirect subsidiary (“MergerCo”), all of the equity interests of which shall be held by a newly formed wholly-owned, direct subsidiary (“New HoldCo”) of Roper, all of the equity interests of which shall be initially be held by Roper. Such merger shall be pursuant to Section 251(g) (or any successor provision) of the Delaware General Corporation Law and shall not require the vote of our stockholders. Each of our shares of common stock shall be converted into a right to receive one share of New HoldCo common stock, with identical terms and rights as our common stock immediately prior to such conversion.

The Indenture governing the debt securities provides that any document or report that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act will be filed with the Trustee within 15 days after such document or report is filed with the SEC.

The following events will be defined in the Indenture as “Events of Default” with respect to debt securities:

(1) the failure to pay interest on any debt securities when the same becomes due and payable and the Default continues for a period of 30 days;

(2) the failure to pay the principal (or premium, if any) of any debt securities, when such principal becomes due and payable, at maturity, upon acceleration, upon redemption or otherwise;

(3) a Default in the performance, or breach, of our obligations under the “—Certain Covenants—Limitation on Mergers and Other Transactions” covenant described above;

(4) a Default in the observance or performance of any other covenant or agreement contained in the Indenture which Default continues for a period of 60 days after we receive written notice specifying the Default (and demanding that such Default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of each series of debt securities affected, voting together as a single class;

(5) (a) a failure to make any payment at maturity on any of our Indebtedness (other than Indebtedness owing to any of our Subsidiaries) outstanding in an amount in excess of $50 million or its foreign currency equivalent at the time and continuance of this failure to pay after any applicable grace period or (b) a default on any of our Indebtedness (other than Indebtedness owing to any of our Subsidiaries), which default results in the acceleration of such Indebtedness in an amount in excess of $50 million or its foreign currency equivalent at the time without such Indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above; provided, however, that if any failure, default or acceleration referred to in clauses 5(a) or (b) ceases or is cured, waived, rescinded or annulled, then the Event of Default under the Indenture will be deemed cured; or

(6) certain events of bankruptcy or insolvency affecting us or any of our Significant Subsidiaries.

If an Event of Default (other than an Event of Default specified in clause (6) above), shall occur and be continuing, the Trustee or the Holders of at least 25% of the principal amount of each series of debt securities affected, voting together as a single class, may declare the principal of and accrued interest on all such debt securities to be due and payable by notice in writing to us and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration”, and the same shall become immediately due and payable.

Notwithstanding the foregoing, if an Event of Default specified in clause (6) above occurs and is continuing, then all unpaid principal of and premium, if any, and accrued and unpaid interest on all debt securities shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Indenture will provide that, at any time after a declaration of acceleration with respect to one or more series of debt securities as described in the preceding paragraph, the Holders of a majority in principal amount of each series of debt securities affected, voting together as a single class, (including additional debt securities of each such series, if any) may rescind and cancel such declaration and its consequences if:

(2) all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

(4) we have paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the Trustee shall have received an officer’s certificate and an opinion of counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the debt securities of each series affected, voting together as a single class, (including additional debt securities of each such series, if any) may waive any existing Default or Event of Default under the Indenture, and its consequences, except a Default in the payment of the principal of or interest on any debt securities of a series.

The Holders may not enforce the Indenture except as provided in the Indenture and under the TIA. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee reasonable indemnity. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of each series of debt securities affected that is then outstanding, voting together as a single class, 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. Nothing herein shall impair the right of a Holder to institute suit for the enforcement of any payment on or with respect to the debt securities.

We will be required to provide an officer’s certificate to the Trustee promptly upon any such officer obtaining knowledge of any Default or Event of Default (provided that such officers shall provide such certification at least annually whether or not they know of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

No Personal Liability of Directors, Officers, Employees, Incorporator and Stockholders

No director, officer, employee, incorporator, agent, stockholder or affiliate of us or any of our Subsidiaries, as such, shall have any liability for any obligations of us or any of our Subsidiaries under the debt securities or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the securities by accepting a note waives and releases all such liability. This waiver and release are part of the consideration for issuance of the debt securities.

We may, at our option and at any time, elect to have our obligations discharged with respect to the outstanding debt securities of a series (“Legal Defeasance”). Such Legal Defeasance means that we shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding debt securities of a series, except for:

(1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the debt securities when such payments are due;

(2) our obligations with respect to the debt securities concerning issuing temporary debt securities, registration of debt securities, mutilated, destroyed, lost or stolen debt securities and the maintenance of an office or agency for payments;

(3) the rights, powers, trust, duties and immunities of the Trustee and our obligations in connection therewith; and

In addition, we may, at our option and at any time, elect to have our obligations released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the applicable series of debt securities. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under “—Events of Default” will no longer constitute an Event of Default with respect to the debt securities.

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the debt securities of a series:

(1) we must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. government obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the debt securities on the stated date for payment thereof or on the applicable Redemption Date, as the case may be;

(2) in the case of Legal Defeasance, we must deliver to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) we have received from, or there has been published by, the Internal Revenue Service a ruling; or

(b) since the date of the Indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, we must deliver to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings);

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a Default under the Indenture (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which we or any of our Subsidiaries is a party or by which we or any our Subsidiaries is bound;

(6) we must deliver to the Trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with;

(7) we must deliver to the Trustee an opinion of counsel to the effect that assuming no intervening bankruptcy of us between the date of deposit and the 91st day following the date of deposit and that no Holder is an insider of us, after the 91st day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

The Indenture will be discharged and will cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the applicable series of the debt securities, as expressly provided for in the Indenture) as to all outstanding debt securities of a series, when:

(A) all of the applicable series of the debt securities theretofore authenticated and delivered (except lost, stolen or destroyed notes which have been replaced or paid and notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by us and thereafter repaid to us or discharged from such trust) have been delivered to the Trustee for cancellation; or

(B) all of the applicable series of debt securities not theretofore delivered to the Trustee for cancellation (l) have become due and payable or (2) will become due and payable within one year, or are to be called for redemption within one year, under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of us, and we have irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the applicable series of debt securities not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the applicable series of debt securities to the date of deposit together with irrevocable instructions from us directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

(3) we have delivered to the Trustee an officer’s certificate and an opinion of counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

From time to time, we and the Trustee, without the consent of the Holders, may amend the Indenture and the applicable series of debt securities for certain specified purposes, including:

(2) to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

(3) to comply with the provisions described under “—Certain Covenants—Limitation on Mergers and Other Transactions”;

(4) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act;

(5) to evidence and provide for the acceptance of appointment by a successor Trustee;

(6) to conform the text of the Indenture or the debt securities to any provision of this “Description of Debt Securities” or other description of the debt securities contained in the prospectus supplement relating to the offer and sale of such debt securities;

(7) to establish the form or terms of the debt securities of any series as permitted by the terms of the Indenture;

(8) to provide for the assumption by a successor corporation, partnership, trust or limited liability company of our obligations under the Indenture, in each case in compliance with the provisions thereof; or

(9) to make any change that would provide any additional rights or benefits to the Holders of the debt securities (including to secure the debt securities, add guarantees with respect thereto, to add to our covenants for the benefit of the Holders or to surrender any right or power conferred upon us) or that does not adversely affect the legal rights hereunder of any Holder of the debt securities in any material respect.

In formulating its opinion on such matters, the Trustee will be entitled to rely on such evidence as it deems appropriate, including, without limitation, solely on an opinion of counsel. Other modifications and amendments of the Indenture may be made with the consent of the Holders of a majority in principal amount of all then outstanding debt securities affected by such modification or amendment (including additional debt securities of each series affected, if any), except that, without the consent of each Holder affected thereby, no amendment may:

(1) reduce the principal amount of debt securities at maturity whose Holders must consent to an amendment;

(2) reduce the rate of, change or have the effect of changing the time for payment of interest, including defaulted interest, on any debt securities;

(3) reduce the principal of, change or have the effect of changing the fixed maturity of any debt securities, or change the date on which any debt securities may be subject to redemption or repurchase or reduce the redemption price or repurchase price therefor;

(4) make any debt securities payable in currency other than that stated in the debt securities or change the place of payment of the debt securities from that stated in the debt securities or in the Indenture;

(5) make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of and interest on such debt securities on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of each series of debt securities affected (including additional debt securities of each such series, if any) to waive Defaults or Events of Default;

(7) make any change to or modify the ranking of the debt securities that would adversely affect the Holders.

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

The Indenture and the provisions of the TIA contain certain limitations on the rights of the Trustee, should it become a creditor of us, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the TIA, the Trustee will be permitted to engage in other transactions; provided that if the Trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

Set forth below is a summary of certain of the defined terms used in the Indenture. Reference is made to the Indenture for the definition of all terms used herein for which no definition is provided.

“Attributable Debt” with regard to a Sale and Lease-Back Transaction with respect to any Principal Property means, at the time of determination, the present value of the total net amount of rent required to be paid under such lease during the remaining term thereof (including any period for which such lease has been extended), discounted at the rate of interest set forth or implicit in the terms of such lease (or, if not practicable to determine such rate, the weighted average interest rate per annum borne by the securities then outstanding under the Indenture) compounded semi-annually. In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount shall be the lesser of (x) the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount shall also include the amount of the penalty, but shall not include any rent that would be required to be paid under such lease subsequent to the first date upon which it may be so terminated) or (y) the net amount determined assuming no such termination.

(1) with respect to any person that is a corporation, any and all shares, interests, participations or other equivalents (however designated and whether or not voting) of corporate stock, including each class of common stock and preferred stock of such person, and all options, warrants or other rights to purchase or acquire any of the foregoing; and

(2) with respect to any person that is not a corporation, any and all partnership, membership or other equity interests of such person, and all options, warrants or other rights to purchase or acquire any of the foregoing.

“Consolidated Net Tangible Assets” means, as of any date on which we effect a transaction requiring such Consolidated Net Tangible Assets to be measured hereunder, the aggregate amount of assets (less applicable reserves) after deducting therefrom: (a) all current liabilities, except for current maturities of long-term debt and obligations under capital leases; and (b) intangible assets (including goodwill), to the extent included in said aggregate amount of assets, all as set forth on our most recent consolidated balance sheet and computed in accordance with generally accepted accounting principles in the United States of America applied on a consistent basis.

“Default” means an event or condition the occurrence of which is, or with the lapse of time or the giving of notice or both would be, an Event of Default.

(1) interest rate swap agreements (whether from fixed to floating or from floating to fixed), interest rate cap agreements and interest rate collar agreements;

(2) other agreements or arrangements designed to manage interest rates or interest rate risk;

(3) other agreements or arrangements designed to protect against fluctuations in currency exchange rates or commodity prices; and

(4) other agreements or arrangements designed to protect against fluctuations in equity prices.

(2) all obligations of such person evidenced by bonds, debentures, notes or other similar instruments.

“Issue Date” means the date of original issuance of a series of debt securities but not any additional debt securities.

“Lien” means any lien, mortgage, deed of trust, hypothecation, pledge, security interest, charge or encumbrance of any kind.

“Principal Property” means the land, improvements, buildings, fixtures and equipment (including any leasehold interest therein) constituting our principal corporate office, any manufacturing plant, or any manufacturing, distribution or research facility (in each case, whether now owned or hereafter acquired) which is owned or leased by us, unless our board of directors has determined in good faith that such office, plant or facility is not of material importance to the total business conducted by us and our Subsidiaries taken as a whole. With respect to any Sale and Lease-Back Transaction or series of related Sale and Lease-Back Transactions, the determination of whether any property is a Principal Property shall be determined by reference to all properties affected by such transaction or series of transactions.

“Sale and Lease-Back Transaction” means any arrangement with any person providing for the leasing by us of any Principal Property, whether now owned or hereafter acquired, which Principal Property has been or is to be sold or transferred by us to such person.

“Significant Subsidiary”, with respect to any person, means, any Subsidiary of such person that satisfies the criteria for a “significant subsidiary” as set forth in Rule 1-02(w) of Regulation S-X under the Exchange Act.

“Subsidiary” means any corporation, limited liability company, limited partnership or other similar type of business entity in which we and/or one or more of our Subsidiaries together own more than 50% of the total voting power of shares of Capital Stock entitled (without regard to the occurrence of any contingency) to vote in the election of the board of directors or similar governing body of such corporation, limited liability company, limited partnership or other similar type of business entity, directly or indirectly.

All funds deposited with the Trustee or any paying agent for the payment of principal, interest, premium or additional amounts in respect of the debt securities that remain unclaimed for two years after the maturity date of such debt securities will be repaid to us upon our request. Thereafter, any right of any noteholder to such funds shall be enforceable only against us, and the Trustee and paying agents will have no liability therefor.

The indenture and the debt securities for all purposes shall be governed by and construed in accordance with the laws of the State of New York.

We maintain ordinary banking relationships and credit facilities with affiliates of Wells Fargo Bank, N.A.

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under either the indenture.

As specified in the applicable prospectus supplement, we may issue units consisting of one or more warrants, debt securities, shares of preferred stock, shares of common stock, purchase contracts or any combination of such securities.

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

We may issue the registered debt securities, warrants and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. 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 securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the 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. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

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 securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement or unit agreement. 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 applicable indenture, warrant agreement or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security

desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Roper, the trustee, any warrant agent, unit agent or any other agent of Roper, agent of the trustee or agent of such warrant agent or unit agent 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 the depositary for any of the securities represented by a registered global security, 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, will 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. We also expect that 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.

If the depositary for any of these 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 us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any 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 relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. 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 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.

We or selling security holders may sell the securities being offered hereby in the following manner or any manner specified in a prospectus supplement:

The prospectus supplement with respect to any offering of securities will set forth the terms of the offering, including:

If any securities are sold pursuant to this prospectus by any persons other than us, we will, in a prospectus supplement, name the selling security holders, indicate the nature of any relationship such holders have had to us or any of our affiliates during the three years preceding such offering, state the amount of securities of the class owned by such security holder prior to the offering and the amount to be offered for the security holder’s account, and state the amount and (if one percent or more) the percentage of the class to be owned by such security holder after completion of the offering.

We or any selling security holder may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933, as amended (the “Securities Act”) and describe any commissions that we or any selling security holder must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we and, if applicable, any selling security holder will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us to indemnification by us and by any selling security holder against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to

determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

The validity of the securities in respect of which this prospectus is being delivered will be passed on for us by Davis Polk & Wardwell, Menlo Park, California.

The financial statements and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Report on Internal Control over Financial Reporting) incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2007 have been so incorporated in reliance on the report, which contains an explanatory paragraph on the effectiveness of internal control over financial reporting due to the exclusion of certain elements of the internal control over financial reporting of JLT Mobile Computers, Inc., Black Diamond Advanced Technology, LLC, DJ Instruments, Dynamic Instruments, Inc. and Roda Deaco Valve, Ltd., which the registrant acquired during fiscal 2007, of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.
