Waiver, Consent and Eleventh Amendment to Credit Agreement, dated July 15, 2019, by and among PROS, Inc., Wells Fargo Bank, National Association, as administrative agent, and the Lenders party thereto

THIS WAIVER, CONSENT AND ELEVENTH AMENDMENT TO CREDIT AGREEMENT (this "Amendment") is entered into as of July [__], 2019, by and among Wells Fargo BANK, National association, a national banking association, as administrative agent ("Agent") for the Lenders (as defined in the Credit Agreement referred to below), the Lenders party hereto, and PROS, INC., a Delaware corporation ("Borrower").

WHEREAS, Borrower, Agent, and Lenders are party to that certain Credit Agreement dated as of July 2, 2012 (as has been, and may hereafter be, amended, restated, modified or supplemented from time to time, the "Credit Agreement");

WHEREAS, Borrower has notified Agent and Lenders that, as of the date hereof and from time to time prior to the date hereof, it has made advances and maintained loans to PROS France SAS, a société par actions simplifiée organized and existing under the laws of France and a direct Subsidiary of Parent ("PROS France"), (a) in excess of the $250,000 aggregate maximum for Permitted Intercompany Advances by a Loan Party to a Subsidiary of Parent that is not a Loan Party set forth on Schedule 1.1 of the Credit Agreement in clause (d)(i) of the definition of "Permitted Intercompany Advances", and (b) in violation of clause (d)(ii) of such definition by making such advances and maintaining such loans (the "PROS France Intercompany Advances") during the existence and continuation of an Event of Default and although an Event of Default would result therefrom;

WHEREAS, in making and maintaining such PROS France Intercompany Advances in violation of the requirements for Permitted Intercompany Advances by a Loan Party to a Subsidiary of Parent that is not a Loan Party, Borrower has failed to observe the covenants set forth in Sections 6.1, 6.9, and 6.10(d) of the Credit Agreement; as a result of such failure, multiple Events of Default have occurred and are continuing under Section 8.2(a)(ii) of the Credit Agreement (collectively, the "Existing Covenant Defaults");

WHEREAS, certain representations and warranties made by the Loan Parties in the Loan Documents prior to the date hereof representing and warranting to the Lender Group that no Default or Event of Default had occurred or was continuing failed to be true and correct in all material respects solely as a result of such Existing Covenant Defaults; as a result of such failure, multiple Events of Default have occurred and are continuing under Section 8.7 of the Credit Agreement (collectively, the "Existing Representation Defaults"; and together with the Existing Covenant Defaults, collectively, the "Existing Defaults");

WHEREAS, Borrower has notified Agent and Lenders that, on or about the date hereof, Parent intends to make a shareholder loan of not more than €6,800,000 to PROS France, (the "Initial Recapitalization Loan") the entirety of which will be subsequently converted into an Investment consisting of €6,800,000 in additional paid-in capital contributed to PROS France in exchange for a corresponding incremental increase in the nominal value per existing share of PROS France currently held by Parent (the "Subsequent Recapitalization Investment") in order to effect a recapitalization of PROS France (such transaction, the "PROS France Recapitalization"), and substantially concurrently therewith, PROS France intends to use a

portion of the proceeds of such advance to repay Borrower in full in respect of the PROS France Intercompany Advances outstanding as of the date of such repayment;

WHEREAS, absent the consent of Agent and Lender, the PROS France Recapitalization would be prohibited under Sections 6.1, 6.9, 6.10, and 6.13 of the Credit Agreement; and

WHEREAS, Borrower has requested that Agent and Lenders (a) waive the Existing Defaults, (b) consent to the PROS France Recapitalization, and (c) amend the Credit Agreement in certain respects as set forth herein, and Agent and Lenders have agreed to the foregoing, on the terms and conditions set forth herein.
