This Amendment Number Two to Credit Agreement (this “Amendment”) is entered into as of September 11, 2014, by and among, on the one hand, the lenders identified on the signature pages hereof (such lenders, together with their respective successors and permitted assigns, are referred to hereinafter each individually as a “Lender” and collectively as the “Lenders”), and WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking association, as administrative agent for each member of the Lender Group and the Bank Product Providers (in such capacity, together with its successors and assigns in such capacity, “Agent”) and CALLIDUS SOFTWARE, INC., a Delaware corporation (“Borrower”), on the other hand, in light of the following:

(e) Wells Fargo as Increasing Lender agrees and acknowledges that the Increase shall constitute a part of the Revolver Commitments under the Credit Agreement, and shall be subject to the same terms applicable to the Revolver Commitments in existence on the effective date of this Amendment in all respects (as such terms may be amended in accordance with the terms of the Credit Agreement), including those relating to interest, payments, repayments, voting and risk participations in Swing Loans, Letters of Credit, Protective Advances and Overadvances.

8. COUNTERPARTS; EFFECTIVENESS. This Amendment may be executed in any number of counterparts and by different parties on separate counterparts, each of which when so executed and delivered shall be deemed to be an original.

and performance of this Amendment shall not operate, except as expressly set forth herein, as a waiver of, consent to, or a modification or amendment of, any right, power, or remedy of Agent or any Lender under the Credit Agreement or any other Loan Document. Except for the amendments to the Credit Agreement expressly set forth herein, the Credit Agreement and the other Loan Documents shall remain unchanged and in full force and effect. The consents, waivers and modifications set forth herein are limited to the specifics hereof, shall not apply with respect to any facts or occurrences other than those on which the same are based, shall neither excuse future non-compliance with the Loan Documents nor operate as a waiver of any Default or Event of Default, shall not operate as a consent to any further or other matter under the Loan Documents and shall not be construed as an indication that any future waiver of covenants or any other provision of the Credit Agreement will be agreed to, it being understood that the granting or denying of any waiver which may hereafter be requested by any Loan Party remains in the sole and absolute discretion of the Agent and the Lenders.

10.2 Upon and after the effectiveness of this Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, “herein”, “hereof” or words of like import referring to the Credit Agreement, and each reference in the other Loan Documents to “the Credit Agreement”, “thereunder”, “therein”, “thereof” or words of like import referring to the Credit Agreement, shall mean and be a reference to the Credit Agreement as modified and amended hereby.

10.3 To the extent that any of the terms and conditions in any of the Loan Documents shall contradict or be in conflict with any of the terms or conditions of the Credit Agreement, after giving effect to this Amendment, such terms and conditions are hereby deemed modified or amended accordingly to reflect the terms and conditions of the Credit Agreement as modified or amended hereby.

10.5 Headings and numbers have been set forth herein for convenience only. Unless the contrary is compelled by the context, everything contained in each Section applies equally to this entire Amendment.
