Granted Under 2016 Omnibus Incentive Plan
    
1.         Grant of Option.
These terms and conditions together with the notice of grant of stock option
(the “Notice”) set forth on the cover page to which they are attached constitute
an Agreement evidencing the grant by Aspen Technology, Inc., a Delaware
corporation (the “Company”), on the grant date set forth in the Notice (the
“Grant Date”) to the employee named in the Notice (the “Participant”), of an
option to purchase, in whole or in part, on the terms provided herein and in the
Company’s 2016 Omnibus Incentive Plan (the “Plan”), the number of shares (the
“Shares”) of common stock, $0.10 par value per share, of the Company (“Common
Stock”) set forth on the Notice, at a strike price set forth per Share set forth
in the Notice.  Unless earlier terminated, this Agreement shall expire at 5:00
p.m., Eastern Time, on the Expiration Date set forth in the Notice (the “Final
Exercise Date”).
To the extent permitted by the Code (as defined below) and designated in the
Notice, it is intended that the option evidenced by this Agreement shall be an
incentive stock option as defined in Section 422 of the Internal Revenue Code of
1986, as amended, and any regulations promulgated thereunder (the “Code”) or a
nonqualified stock option, to the extent designated in this Notice.
2.         Vesting Schedule.
The options granted hereunder will vest according to the schedule set forth on
the Notice. The right of exercise shall be cumulative so that to the extent the
option is not exercised in any period to the maximum extent permissible it shall
continue to be exercisable, in whole or in part, with respect to all Shares for
which it is vested until the earlier of the Final Exercise Date or the
termination of this Agreement under Section 3 hereof or the Plan.
3.         Exercise of Option.
(a)    Form of Exercise.  Each election to exercise this Agreement shall be in
the manner permitted by the Company’s third party stock incentive plan
administrator.  If no such third party administrator is administering the Plan
at such time, such election shall be in writing, signed by the Participant and
received by the Company at its principal office, accompanied by this Agreement
and payment in full in the manner provided in the Plan, or as otherwise provided
in the Plan.  The Participant may purchase less than the number of shares
covered hereby, provided that no partial exercise of this Agreement may be for
any fractional share.
(b)    Continuous Relationship with the Company Required.  Except as otherwise
provided in this Section 3, this Agreement may not be exercised unless the
Participant, at the time he or she exercises this Agreement, is, and has been at
all times since the Grant Date, an employee or officer of, or consultant or
advisor to, the Company or any parent or subsidiary of the Company as defined in
Section 424(e) or (f) of the Code (an “Eligible Participant”).
(c)    Termination of Relationship with the Company.  If the Participant ceases
to be an Eligible Participant for any reason, then, except as provided in
paragraphs (d) and (e) below, the right to exercise this Agreement shall
terminate three months after such cessation (but in no event after the Final
Exercise Date), provided that this Agreement shall be exercisable only to the
extent that the Participant was entitled to exercise this Agreement on the date
of such cessation.  Notwithstanding the foregoing, if the Participant, prior to
the Final Exercise Date, violates the non-competition or confidentiality
provisions of any employment contract, confidentiality and nondisclosure
agreement or other agreement between the Participant and the Company, the right
to exercise this Agreement shall terminate immediately upon such violation.
(d)    Exercise Period Upon Death or Disability.  Unless otherwise agreed by the
Company and the Participant, if the Participant dies or becomes disabled (within
the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date
while he or she is an Eligible Participant and the Company has not terminated
such relationship for “cause” as specified in paragraph (e) below, this
Agreement shall be exercisable, within the period of eighteen months following
the date of death, or one year following the date of disability, of the
Participant, by the Participant (or in the case of death by an authorized
transferee), provided that this Agreement shall be exercisable only to the
extent that this

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

Agreement was exercisable by the Participant on the date of his or her death or
disability, and further provided that this Agreement shall not be exercisable
after the Final Exercise Date.
(e)     Termination for Cause.  If, prior to the Final Exercise Date, the
Participant’s employment is terminated by the Company for Cause (as defined
below), the right to exercise this Agreement shall terminate immediately upon
the effective date of such termination of employment, unless otherwise agreed by
the Company and the Participant.  If the Participant is party to an employment
or severance agreement with the Company that contains a definition of “cause”
for termination of employment, “Cause” shall have the meaning ascribed to such
term in such agreement.  Otherwise, “Cause” shall mean (i) any willful failure
by the Participant, which failure is not cured within 30 days of written notice
to the Participant from the Company, to perform his or her material
responsibilities to the Company, or (ii) willful misconduct by the Participant
that affects the business reputation of the Company, in either case as
determined by the Company, which determination shall be conclusive.
4.         Tax Matters.
(a)    Withholding.  No Shares will be issued pursuant to the exercise of this
Agreement unless and until the Participant pays to the Company, or makes
provision satisfactory to the Company for payment of, any federal, state or
local withholding taxes required to be withheld in respect of this Agreement. To
satisfy any such tax obligation, the Company may deduct and retain from the
Shares to be issued upon exercise of the Option such number of Shares as is
equal in value up to the Company’s maximum statutory withholding obligations
with respect to the income recognized by the Participant upon such exercise
(based on statutory withholding rates for federal and state tax purposes,
including payroll taxes, that are applicable to such income), and pay the
required amounts to the relevant taxing authorities.
(b)    Disqualifying Disposition.  To the extent the option is an incentive
stock option, if the Participant disposes of Shares acquired upon exercise of
this Agreement within two years from the Grant Date or one year after such
Shares were acquired pursuant to exercise of this Agreement, the Participant
shall notify the Company in writing of such disposition.
5.         Nontransferability of Option.
This Agreement may not be sold, assigned, transferred, pledged or otherwise
encumbered by the Participant, either voluntarily or by operation of law, except
by will or the laws of descent and distribution, and, during the lifetime of the
Participant, this Agreement shall be exercisable only by the Participant.
6.         Provisions of the Plan; Change in Control.
This Agreement is subject to the provisions of the Plan, the terms of which are
incorporated herein by reference. A prospectus describing the Plan has been
delivered to the Participant. The Plan itself is available upon request. In that
regard, the Option is subject to adjustment in connection with a change in
capital of the Company or a Corporate Transaction, as provided in Sections 15.1
and 15.2 of the Plan. In addition, vesting of the Option in connection with a
Change in Control shall be determined in accordance with Section 15.3 of the
Plan. For purposes of Section 15.3.1(ii) of the Plan, if the Option is assumed,
converted or replaced by the resulting entity in the Change in Control, if,
within one year after the date of the Change in Control, the Participant has a
Separation from Service by the Company other than for Cause or by the
Participant for Good Reason, any unvested portion of the Option shall become
fully vested and exercisable as of the date of such Separation from Service. For
this purpose, “Cause” and “Good Reason” mean as follows:
"Cause" is as defined in Section 3(e) above.
 "Good Reason" means any significant diminution in the Participant's title,
authority, or responsibilities from and after the Change in Control, or any
reduction in the annual cash compensation payable to the Participant from and
after the Change in Control.

7.    Miscellaneous.
(a)      No Rights to Employment.   The Participant acknowledges and agrees that
the vesting and exercisability of the Option shall be in accordance with the
vesting schedule set forth in the Notice, and is contingent upon status as an
employee at the time of vesting at the will of the Company (not through the act
of being hired). The Participant further

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

acknowledges and agrees that the transactions contemplated hereunder and the
vesting schedule set forth in the Notice do not constitute an express or implied
promise of continued engagement as an employee or consultant for the vesting
period, for any period, or at all.
(b)       Severability.   The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, and each other provision of this Agreement shall be
severable and enforceable to the extent permitted by law.

this Agreement may be waived, either generally or in any particular instance, by
the Board of Directors of the Company.

the benefit of the Company and the Participant and their respective heirs,
executors, administrators, legal representatives, successors and assigns,
subject to the restrictions on transfer set forth in Section 5 of this
Agreement.
