This First Amendment to Third Amended and Restated Credit Agreement, dated as of
October 31, 2018 (this “Amendment”), is among Altair Engineering Inc. (the
“Borrower”), the Lenders party hereto, and JPMorgan Chase Bank, N.A., as
Administrative Agent (in such capacity, the “Administrative Agent”).

RECITAL

The Borrower, the Lenders party thereto and the Administrative Agent are parties
to a Third Amended and Restated Credit Agreement dated as of October 18, 2017
(as it may be amended or modified from time to time, the “Credit Agreement”).
The Borrower desires to amend the Credit Agreement as set forth herein and the
Lenders are willing to do so in accordance with the terms hereof. Capitalized
terms used herein, but not otherwise defined shall have the meanings ascribed to
them in the Credit Agreement.

TERMS

In consideration of the premises and of the mutual agreements herein contained,
the parties agree as follows:

ARTICLE 1.

AMENDMENTS

Upon the satisfaction of the conditions set forth in Article 4 hereof, the
Credit Agreement shall be amended as follows:

1.1    The following definitions are added to Section 1.01 of the Credit
Agreement in their respective alphabetical location.

“First Amendment” means the First Amendment to the Third Amended and Restated
Credit Agreement dated as of the First Amendment Effective Date by and among the
Borrower, the Lenders party thereto and the Administrative Agent.

“First Amendment Effective Date” means October 31, 2018.

1.2    The following definitions in Section 1.01 of the Credit Agreement are
restated as follows:

“Prime Rate” means the rate of interest last quoted by The Wall Street Journal
as the “Prime Rate” in the U.S. or, if The Wall Street Journal ceases to quote
such rate, the highest per annum interest rate published by the Federal Reserve
Board in Federal Reserve Statistical Release H.15 (519) (Selected Interest
Rates) as the “bank prime loan” rate or, if such rate is no longer quoted
therein, any similar rate quoted therein (as determined by the Administrative
Agent) or any similar release by the Federal Reserve Board (as determined by the
Administrative Agent). Each change in the Prime Rate shall be effective from and
including the date such change is publicly announced or quoted as being
effective.

--------------------------------------------------------------------------------

“Revolving Commitment” means, with respect to each Lender, the commitment, if
any, of such Lender to make Revolving Loans and to acquire participations in
Letters of Credit and Swingline Loans hereunder, expressed as an amount
representing the maximum aggregate permitted amount of such Lender’s Revolving
Exposure hereunder, as such commitment may be reduced or increased from time to
time pursuant to (a) Section 2.09 or 2.23 of this Agreement and (b) assignments
by or to such Lender pursuant to Section 9.04. The initial amount of each
Lender’s Revolving Commitment is set forth on the Commitment Schedule, or in the
Assignment and Assumption pursuant to which such Lender shall have assumed its
Revolving Commitment, as applicable. The aggregate amount of the Lenders’
Revolving Commitments as of the Effective Date is $100,000,000, and the
aggregate amount of the Lenders’ Revolving Commitments as of the First Amendment
Effective Date is $150,000,000.

1.3    The Commitment Schedule attached to the Credit Agreement is replaced with
the Commitment Schedule attached hereto.

1.4    Notwithstanding anything in the Credit Agreement to the contrary, the
parties hereto acknowledge and agree that this Amendment shall be not deemed to
have used the allowable increase of the Aggregate Revolving Commitments under
Section 2.23.

ARTICLE 2.

REPRESENTATIONS.

In order to induce the Lenders and the Administrative Agent to enter into this
Amendment, each Loan Party represents and warrants to each Lender and the
Administrative Agent that the following statements are true, correct and
complete as of the First Amendment Effective Date:

2.1    The execution, delivery and performance of this Amendment are within its
powers and have been duly authorized by it.

2.2    This Amendment is the legal, valid and binding obligation of it,
enforceable against it in accordance with the terms hereof, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting creditors’ rights generally and subject to general principles of
equity, regardless of whether considered in a proceeding in equity or at law.

2.3    After giving effect to the amendments herein contained, the
representations and warranties of each Loan Party set forth in the Credit
Agreement or in any other Loan Document shall be true and correct in all
material respects on and as of the First Amendment Effective Date (it being
understood and agreed that any representation or warranty which by its terms is
made as of a specified date shall be required to be true and correct in all
material respects only as of such specified date, and that any representation or
warranty which is subject to any materiality qualifier shall be required to be
true and correct in all respects).

amended from time to time. This Amendment is a Loan Document.

Documents are ratified and confirmed and shall remain in full force and effect
