Item 1.01 Entry into a Material Definitive Agreement.

Accelerated Share Repurchase

On June 14, 2012, Flowserve Corporation, a New York Corporation (the “Company”) entered into an accelerated share repurchase agreement (the “ASR Agreement”) with J.P. Morgan Securities LLC, as agent for JPMorgan Chase Bank, National Association, London Branch (the “Seller”), under which the Company will repurchase an aggregate of $300 million of its common stock, par value $1.25 per share (“Common Stock”).

The ASR Agreement requires the Seller to deliver to the Company on June 15, 2012, a number of shares of Common Stock equal to 80 percent of the shares that would be repurchased at a price of $106.16, the closing price of the Common Stock on June 14, 2012. The final number of shares to be delivered to the Company by the Seller under the ASR Agreement at program maturity, net of the initial delivery, will be adjusted based on an agreed upon discount to the average of the daily volume weighted average price of the Common Stock during the term of the ASR Agreement. If the number of shares to be delivered to the Company at maturity is less than the initial delivery of shares by the Seller, the Company would be required to remit shares or cash, at the Company’s option, to the Seller in an amount then equivalent to such shortfall.

The ASR Agreement is subject to terms believed to be customary for a transaction of this type, including, but not limited to, (i) the mechanism used to determine the number of shares that will be delivered, (ii) the required timing of delivery of the shares, (iii) the circumstances under which the Seller is permitted to make adjustments to the transaction terms, (iv) the circumstances under which the ASR Agreement may be terminated early, (v) the circumstances under which the Company could be required to deliver cash or shares (at the Company’s option) to the Seller upon settlement of the transaction and (vi) various acknowledgements, representations and warranties made by the parties to one another.

The Company entered into the ASR Agreement as part of the Company’s $1 billion share repurchase program that was authorized by its Board of Directors and previously announced on May 31, 2012. Excluding the ASR Agreement described above, the amount and timing of planned repurchases will be determined by the Company based on its evaluation of the Company’s financial condition, business opportunities and market conditions at the time.

Bridge Loan

Effective June 15, 2012 (the “Closing Date”), the Company entered into a Loan Agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the other lenders party thereto (together, the “Lenders”), providing for a term loan with an aggregate commitment of $250 million for a term of 364 days (the “Bridge Loan”).

The initial interest rates per annum applicable to the Bridge Loan will be either LIBOR plus 2.50%, 2.25%, 2.00% or 1.75%, as applicable, depending on the consolidated leverage ratio, or, at the option of the Company, the Base Rate (defined as a rate per annum equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus  ¹/2 of 1% and (c) the Eurodollar Rate for a one month Interest Period on such day (or if such day is not a business day, the immediately preceding business day) plus 1%). The applicable interest rate will increase by 50 basis points incrementally during the term of the Bridge Loan on each of the 90 day, 180 day and 270 day anniversaries of the Closing Date. Additionally, a duration fee will be payable on the loan amount as follows: 0.125% on the 120 day anniversary of the Closing Date; 0.25% on the 180 day anniversary of the Closing Date; and 0.5% on the 270 day anniversary of the Closing Date.

The Bridge Loan includes customary representations and warranties, affirmative and negative covenants, and events of default, including maintenance of interest coverage and consolidated leverage ratios, all of which are consistent in all material respects with the Company’s existing credit facility.

The Company’s obligations under the Bridge Loan are guaranteed by certain domestic subsidiaries of the Company. The guarantors have agreed that if any of the Company’s obligations are not paid in full when due, the guarantors will, jointly, and severally, promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the obligations, the same will be promptly paid in full when due.
