LIMITED WAIVER

Ladies and Gentlemen:

We refer to the Credit Agreement, dated as of December 19, 2011 (as amended, modified, supplemented or extended from time to time, the “Credit Agreement”), by and among TIBCO Software Inc., a Delaware corporation (the “Company”), certain Subsidiaries of the Company from time to time party thereto as Designated Borrowers, the Lenders from time to time party thereto, and Bank of America, N.A., as Administrative Agent (in such capacity, the “Administrative Agent”). Capitalized terms used herein and not otherwise defined herein shall have the respective meanings given to them in the Credit Agreement.

The Company has informed the Administrative Agent and the Lenders that the Company intends to (a) issue, on or about April 23, 2012, up to $600,000,000 in aggregate principal amount of convertible senior unsecured notes, which issuance (such issuance, the “Debt Issuance”) will be (subject to the terms hereof) in accordance with the terms of the Credit Agreement, including, in particular, Section 7.03(k) thereof, and (b) substantially concurrently with the Debt Issuance, use the proceeds thereof in part to purchase (such purchase, together with the Debt Issuance, the “Subject Transactions”) for cash up to $150,000,000 of Equity Interests issued by the Company. In connection with the Subject Transactions, the Company has requested that the Required Lenders waive compliance with certain provisions of the Credit Agreement in order to facilitate the Subject Transactions by the Company.

By this Waiver Letter, the Required Lenders hereby waive compliance by the Company with:

(a) for the period from (and including) the Waiver Effective Date (as defined below) to (but excluding) May 18, 2012 (such period, the “Waiver Period”), clause (ii) of Section 7.03(k) of the Credit Agreement, solely in respect of any failure by the Company and its Subsidiaries to be in pro forma compliance with Section 7.11(b) of the Credit Agreement immediately after giving pro forma effect to the Subject Transactions; and

(b) on a permanent basis, clause (g)(ii)(B) of Section 7.06 of the Credit Agreement, solely in respect of any failure by the Company and its Subsidiaries to have a Consolidated Leverage Ratio of less than 2.25:1.00 immediately after giving pro forma effect to the Subject Transactions.

Without in any way limiting the foregoing waivers, the parties hereto acknowledge, understand and agree that failure by the Company and its Subsidiaries to be in pro forma compliance with Section 7.11(b) of the Credit Agreement on and as of May 18, 2012 (such compliance to be determined on the basis of the financial information most recently delivered to the Administrative Agent and the Lenders pursuant to Section 6.01(b) of the Credit Agreement as though the Subject Transactions (and all repayments and/or prepayments of Indebtedness that actually occurred at any time during the Waiver Period) had been consummated as of the first day of the fiscal period covered thereby) shall constitute an immediate Event of Default.

The Company acknowledges and agrees that (a) except as expressly modified by this Waiver Letter, the Credit Agreement and each other Loan Document shall remain unchanged and shall continue in full force and effect in accordance with their terms, and this Waiver Letter shall be strictly limited to its terms with respect to the express provisions temporarily waived hereunder, and to this occasion alone and (b) no waiver or approval by any Lender hereunder shall (i) be applicable to subsequent transactions or (ii) require any other waiver (whether similar or dissimilar to the waivers granted by this Waiver Letter).

The Company further acknowledges and agrees that (a) this Agreement is not intended to, nor shall it, establish any course of dealing between the Company, the Administrative Agent and the Lenders, or any thereof, that is inconsistent with the express terms of the Credit Agreement and the other Loan Documents; (b) notwithstanding any course of dealing between the Company, the Administrative Agent and the Lenders, or any thereof, prior to the date hereof, except as set forth herein, the Administrative Agent and the Lenders shall not be obligated to make any Loan or issue any Letter of Credit, except in accordance with the terms and conditions of the Credit Agreement and the other Loan Documents; and (c) except with respect to the limited waiver granted herein, the Administrative Agent and the Lenders shall not be under any obligation to forbear from exercising any of their respective rights or remedies upon the occurrence of any Default or Event of Default.

In order to induce the Lenders to grant the foregoing waivers, the Company hereby

(a) confirms and restates all representations and warranties contained in the Credit Agreement and the Loan Documents as of the date hereof;

(b) confirms that, as of the date hereof, no Default has occurred and is continuing; and

(c) covenants and agrees to deliver to the Administrative Agent and the Lenders, as soon as reasonably practicable following consummation of the Subject Transactions and all contemplated repayments and/or prepayments of Indebtedness with the proceeds of the Debt Issuance (and, in any event, no later than the last day of the Waiver Period), a duly completed pro forma Compliance Certificate signed by the chief executive officer, chief financial officer, treasurer or controller of the Company, which Compliance Certificate shall demonstrate pro forma compliance with Section 7.11 of the Credit Agreement (such compliance to be determined on the basis of the financial information most recently delivered to the Administrative Agent and the Lenders pursuant to Section 6.01(b) of the Credit Agreement as though the Subject Transactions (and all repayments and/or prepayments of Indebtedness that actually occurred at any time during the Waiver Period) had been consummated as of the first day of the fiscal period covered thereby).
