INCREMENTAL FACILITY AMENDMENT, dated as of August 9, 2017 (this “Incremental Facility Amendment”) to the Credit Agreement, dated as of February 26, 2016 (as amended or modified from time to time, the “Credit Agreement”), among Aspen Technology, Inc. (the “Borrower”), each lender from time to time party thereto (collectively, the “Lenders” and individually, a “Lender”), JPMORGAN CHASE BANK, N.A., as Administrative Agent and Issuing Bank and certain other Lenders acting in such capacity from time to time, as Issuing Banks.

WHEREAS, pursuant to the Credit Agreement, the Lenders have agreed to make, and have made, certain loans and other extensions of credit to the Borrower;

WHEREAS, the Borrower desires to amend Schedule 3.11 of the Credit Agreement and, pursuant to Section 2.20 of the Credit Agreement, has requested an increase in the aggregate Revolving Credit Commitments under the Credit Agreement in an amount of $100,000,000;

WHEREAS, each Lender signatory to this Incremental Facility Amendment (each, an “Incremental Facility Lender”) has agreed to, among other things, provide the additional Revolving Credit Commitments in the amount set forth opposite to its name in the commitment schedule attached hereto as Schedule A (the “Incremental Commitment Schedule”; such additional Incremental Revolving Commitments set forth in the Incremental Commitment Schedule, the “Incremental Commitments”) upon the terms and subject to the conditions set forth herein;

WHEREAS, JPMorgan Chase Bank, N.A. and Silicon Valley Bank are appointed by the Borrower to act as Joint Lead Arrangers and Joint Bookrunners for the Incremental Commitments;

NOW, THEREFORE, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.    Defined Terms. Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement.

SECTION 2.    Incremental Revolving Credit Commitments.

(a)    On the Increase Effective Date (as defined below), this Incremental Facility Amendment shall constitute an increase in the Revolving Credit Commitments of the Lenders pursuant to Section 2.20 of the Credit Agreement, the Incremental Commitments shall constitute additional “Revolving Credit Commitments” and any loans made pursuant to the Incremental Commitments shall constitute “Revolving Loans” and “Loans” under the Credit Agreement.

(b)    The Incremental Commitments shall have the same terms and conditions as those of the Revolving Credit Commitments existing prior to the Increase Effective Date under the Credit Agreement. No increase of the Revolving Increase Commitments pursuant to this Incremental Facility Amendment increases the Letter of Credit Facility set forth in the Credit Agreement.

(c)    From the Increase Effective Date until the Maturity Date, all Revolving Loans shall be made in accordance with the Revolving Credit Commitments of the Lenders after giving effect to the Incremental Commitments. If any Revolving Loans are outstanding on the Increase Effective Date, the Lenders immediately after effectiveness of such Incremental Commitment shall purchase and assign at par such amounts of the Revolving Loans outstanding at such time as the Administrative Agent may require such that each Lender holds its Pro Rata Share of all Revolving Loans outstanding after giving effect to all such assignments. On the Increase Effective Date, each Incremental Facility Lender will automatically and without further act be deemed to have assumed a portion in outstanding Letters of Credit such that, after giving effect to such deemed assignment and assumption of participations, the percentage of the aggregate outstanding participations in Letters of Credit held by such Incremental Facility Lender equals its Pro Rata Shares (after giving effect to the Incremental Commitments). For the avoidance of doubt, it is understood that facility fees with respect to the Incremental Commitments shall accrue from the Increase Effective Date.

SECTION 3.    Schedule 3.11 Amendment. Schedule 3.11 to the Credit Agreement is deleted in its entirety and replaced with the Schedule attached as Schedule C hereto

SECTION 4.    Fees. The Borrower agrees to pay on the Increase Effective Date to the Administrative Agent, for the account of each Incremental Facility Lender, fees in the amounts previously communicated by the Borrower and the Arrangers to each such Incremental Facility Lender.

SECTION 5.    Amendments to Credit Agreement to Reflect the Incremental Commitments. Schedule 2.01 of the Credit Agreement is hereby replaced with the revised Revolving Credit Commitments schedule attached hereto as Schedule B.

SECTION 6.    Effectiveness of Incremental Facility Amendment. This Incremental Facility Amendment shall become effective upon satisfaction of the following conditions precedent (such date, the “Increase Effective Date”):

(a)    counterparts to this Incremental Facility Amendment duly executed by the Borrower, each other Loan Party and each Incremental Facility Lender;

(b)    a fee for the account of each Incremental Facility Lender that is a party to this Incremental Facility Amendment in accordance with Section 4 hereof;

(c)    all other fees required to be paid, and all expenses for which invoices have been presented (including the reasonable and documented fees and reasonable, documented, out-of-pocket expenses of legal counsel) required to be paid in accordance with the Loan Documents;

(d)    a certificate of the Borrower dated as of the Increase Effective Date (i) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such increase, and (ii) certifying that, before and after giving effect to such increase, (A) the representations and warranties contained in the Loan Documents are true and correct in all material respects (except for representations and warranties qualified as to materiality and Material Adverse Effect, which shall be true and correct in all respects) on and as of Increase Effective Date, as though made on and as of such date (except to the extent any such representation or warranty specifically relates to an earlier date in which case such representation and warranty shall be accurate in all material respects as of such earlier date), and (B) no event has occurred and its continuing, or would result from the Incremental Commitments, that constitutes a Default or Event of Default; and

(e)    a signed opinion, dated as of the Increase Effective Date, addressed to the Administrative Agent and the Incremental Facility Lenders from legal counsel to the Borrower covering the matters reasonably requested by the Administrative Agent.

SECTION 7.    Representations and Warranties. To induce the other parties hereto to enter into this Incremental Facility Amendment and to provide the Incremental Commitments, the Borrower and each other Loan Party hereby represents and warrants to the Administrative Agent and to each Incremental Facility Lender, as of the Increase Effective Date:
