INTRODUCTORY NOTE

On September 10, 2013, BMC Software, Inc. (the “Company”) completed its previously announced merger (the “Merger”) with Boxer Merger Sub Inc. (“Merger Sub”), a wholly-owned subsidiary of Boxer Parent Company Inc. (“Parent”), pursuant to that certain Agreement and Plan of Merger, dated as of May 6, 2013 and amended as of July 24, 2013, by and among the Company, Parent and Merger Sub (the “Merger Agreement”). The Company was the surviving corporation in the Merger and, as a result of the Merger, has become a wholly-owned subsidiary of Parent.

New Credit Facilities

Overview

On September 10, 2013, BMC Software Finance, Inc., a newly formed Delaware subsidiary of Parent and the parent of the Company, as the US Borrower (“US Borrower”), BMC Foreign Holding Company, a newly formed unlimited company incorporated in Ireland and an indirect subsidiary of US Borrower, as the Foreign Borrower (“Foreign Borrower”, and together with the US Borrower, the “Borrowers” and each individually a “Borrower”) and Parent entered into the Credit Agreement, dated as of September 10, 2013 (the “Credit Agreement”), with the Lenders party thereto and Credit Suisse AG, Cayman Islands Branch, as Administrative Agent and Collateral Agent (“Agent”).

The Credit Agreement provides for (i)(a) US term loans denominated in US Dollars to US Borrower in an aggregate original principal amount of $2,880,000,000 (the “US Term Loans”), and (b) foreign term loans (the “Foreign Term Loans” and, collectively with the US Term Loans, the “Term Loans”) comprised of (x) foreign term loans denominated in US Dollars to Foreign Borrower in an aggregate original principal amount of $335,000,000 (the “Foreign USD Term Loans”) and (y) foreign term loans denominated in Euros to Foreign Borrower in an aggregate original principal amount of €500,000,000 (the “Foreign Euro Term Loans”), in the case of each of the foregoing clauses (a) and (b), under the new senior secured term loan facilities (the “Term Loan Facilities”) and (ii)(a) US revolving loans to US Borrowers of up to $170,000,000 (including letters of credit) (the “US Revolving Loans”) and (b) multicurrency revolving loans to the Borrowers of up to $180,000,000 (including letters of credit), a portion of which may be denominated in US Dollars, Euro, Sterling, Yen, Australian Dollars, Canadian Dollars, New Zealand Dollars, Brazilian Reais, Mexican Pesos, Argentine Pesos, Swiss Francs or other currency that may be agreed (the “Multicurrency Revolving Loans”), under the new senior secured revolving loan facilities (the “Revolving Credit Facilities” and, together with the Term Loan Facilities, the “Credit Facilities”). Concurrently with the consummation of the Merger, the full amount of the Term Loan Facilities was drawn, and no amount under the Revolving Credit Facilities was drawn. The Credit Agreement also permits the Borrowers to establish incremental revolving credit commitments or incur secured or unsecured incremental term loans or notes at any time, from time to time, after the closing subject to the terms and conditions set forth therein.

Interest Rate and Fees

At the Company’s election, the interest rate per annum applicable to the loans under the Credit Facilities will be based on a fluctuating rate of interest determined by reference to either (i) a base rate determined by reference to the higher of (a) the “prime rate” of Credit Suisse AG, Cayman Islands Branch, (b) the federal funds effective rate plus 0.50% and (c) the Eurocurrency rate applicable for an interest period of one month plus 1.00%, plus an applicable margin equal to (x) 3.00%, in the case of the US Term Loans and the Foreign USD Term Loans, (y) 3.00% in the case of the US Revolving Loans or (z) 2.50% in the case of the Multicurrency Revolving Loans or (ii) a Eurocurrency rate determined by reference to LIBOR, adjusted for statutory reserve requirements, plus an applicable margin equal to (w) 4.00%, in the case of the US Term Loans and the Foreign USD Term Loans, (x) 4.50% in the case of the Foreign Euro Term Loans, (y) 4.00% in the case of the US Revolving Loans or (z) 3.5% in the case of the Multicurrency Revolving Loans. The Term Loan Facilities will be subject to a Eurocurrency rate floor of 1.00%. Under the Revolving Credit Facilities, (i) a commitment fee of .50% will accrue on the undrawn amount of the US Revolving Facility and (ii) a facility fee of .50% will accrue on all drawn or undrawn amounts under the Multicurrency Revolving Facility. The applicable margin, commitment fees and facility fees for loans under the Revolving Credit Facilities will be adjusted after each fiscal quarter of the Company commencing with the Company’s first full fiscal quarter after the closing based upon the Company’s first lien net leverage ratio.

Prepayments

Subject to certain exceptions, the Term Loans are subject to mandatory prepayments in amounts equal to: (1) 100% of the net proceeds (determined by taking into account any indebtedness secured pari passu with the Term Loan Facilities that is prepaid with such net cash proceeds) from certain non-ordinary course sales or other dispositions of assets including sale-leasebacks and casualty or condemnation by the US Borrower or any Restricted Subsidiaries (as defined in the Credit Agreement) in excess of a certain amount and subject to customary reinvestment provisions and certain other exceptions; (2) 100% of the net cash proceeds from the issuance or incurrence of debt by the US Borrower or any Restricted Subsidiaries (other than indebtedness permitted by the Credit Facilities); and (3) beginning with the first full fiscal year after the closing, 50% (with step-downs to 25% and 0% based upon achievement of specified first lien net leverage ratios) of annual excess cash flow of the US Borrower and the Restricted Subsidiaries. Subject to certain prepayment premiums and penalties and the payment of customary “breakage” costs, the Company may voluntarily prepay outstanding loans at any time.

Amortization

The Term Loan Facilities initially have a seven-year maturity and the Revolving Credit Facilities initially have a five-year maturity, each of which may be extended in accordance with the terms therein.

and its subsidiaries by any lender party to the Credit Facilities or any of its affiliates are secured on a first priority basis by a perfected security interest in substantially all of the tangible and intangible assets (subject to certain exceptions) of the Foreign Borrower, Foreign Parent Loan Parties and each Foreign Subsidiary Loan Party party thereto, including registered intellectual property and all of the capital stock of each of the Foreign Borrower’s direct and indirect wholly-owned material Restricted Subsidiaries, including the Foreign Borrower.

Certain Covenants and Events of Default

The Credit Facilities contain a number of customary affirmative and negative covenants that, among other things, will limit or restrict the ability of the Borrowers and each Restricted Subsidiary, subject to certain exceptions, to: incur additional indebtedness (including guarantee obligations); incur liens; engage in mergers, consolidations, liquidations and dissolutions (other than pursuant to the transactions contemplated by the Merger Agreement); sell assets; pay dividends and make other payments in respect of capital stock; make acquisitions, investments, loans and advances; pay and modify the terms of certain indebtedness; engage in certain transactions with affiliates; enter into negative pledge clauses and clauses restricting subsidiary distributions; and change its line of business.

In addition, under the Revolving Credit Facilities, the US Borrower and its Restricted Subsidiaries will be required to not exceed a specified first lien net leverage ratio in the event that amounts outstanding under the Revolving Credit Facilities, (excluding issued and undrawn letters of credit) exceed 30% of the commitments under the Revolving Credit Facilities as of the end of any fiscal quarter. The financial covenant is subject to customary equity cure rights.

The Credit Facilities contain customary events of default, including nonpayment of principal, interest, fees or other amounts; material inaccuracy of a representation or warranty when made; violation of a covenant; cross-default to material indebtedness; bankruptcy events; material unsatisfied monetary judgments; actual or asserted invalidity of any loan document and material impairment of the security and/or guarantees; and a change of control. The Company’s ability to borrow under the Credit Facilities will be dependent on, among other things, its compliance with the above-described financial ratio.
