      Offering Period, by reason of the inability to purchase a fractional share, shall be carried forward to the next Offering Period, subject to earlier withdrawal by the Participant in accordance with Section 10 or termination of employment in
      accordance with Section 11. Any accumulated payroll deductions that remain in a Participant’s notional account after applying the limitations of Section 4.2 and Section 7 shall be returned to the Participant as soon as administratively practicable.

      permit or require that the shares be deposited directly into an ESPP Share Account established in the name of the Participant with a Designated Broker. A Participant may not sell or otherwise dispose of shares deposited in his or her ESPP Share
      Account earlier than twelve (12) months following the applicable Purchase Date (or such shorter periods as the Committee may establish). In addition, in the absence of a permitted disposition and if the shares are held with a Designated Broker, the
      shares must be held in the ESPP Share Account with the Designated Broker until eighteen (18) months after the Purchase Date (or such other period as established by the Committee at the beginning of the Offering Period for which the shares were
      purchased).

        (that have not been used to purchase shares of Common Stock) shall be paid to the Participant promptly after receipt of the Participant’s Enrollment Form indicating his or her election to withdraw and the Participant’s option shall be automatically
        terminated. If a Participant withdraws from an Offering Period, no payroll deductions shall be made during any succeeding Offering Period, unless the Participant re-enrolls in accordance with Section 6.1.

    	11.	
            Termination of Employment; Change in Employment Status

          

    

    

    Upon termination of a Participant’s employment from the Company and the Participating Subsidiaries for any reason or at any time, or a change in the Participant’s employment status after which the Participant is no
      longer an Eligible Employee, the Participant shall be deemed to have withdrawn from this Plan and the payroll deductions in the Participant’s notional account (that have not been used to purchase shares of Common Stock) shall be returned to the
      Participant, or in the case of the Participant’s death, to the person(s) entitled to such amounts under Section 17, and the Participant’s option shall be automatically terminated.

    

    

    	12.

        total of 179,082 shares of Common Stock have been reserved as authorized for the grant of options under this Plan. The shares of Common Stock may be newly issued shares, treasury shares, or shares acquired on the open market. If an option under
        this Plan expires or is terminated unexercised for any reason, the shares as to which such option so expired or terminated again may be made subject to an option under this Plan.

    

    

    13.2          Oversubscribed Offerings. The number of shares of Common Stock that a
        Participant may purchase in an Offering under this Plan may be reduced if the Offering is oversubscribed. No option granted under this Plan shall permit a Participant to purchase shares of Common Stock that, if added together with the total number
        of shares of Common Stock purchased by all other Participants in such Offering, would exceed the total number of shares of Common Stock remaining available under this Plan. If, on a particular Purchase Date, the number of shares of Common Stock
        with respect to which options are to be exercised exceeds the number of shares of Common Stock then available under this Plan, the Company shall make a pro rata allocation of the shares of Common Stock remaining available for purchase in as uniform
        a manner as practicable and as the Committee determines to be equitable.

    

    

    	14.	
            Transferability

          

    

    

    No payroll deductions credited to a Participant, nor any rights with respect to the exercise of an option or any rights to receive Common Stock hereunder, may be assigned, transferred, pledged, or otherwise disposed of
      in any way (other than by will, the laws of descent and distribution, or as provided in Section 17) by the Participant. Any attempt to assign, transfer, pledge, or otherwise dispose of such rights or amounts shall be without effect.

        the Transaction Agreement, in the event that any dividend or other distribution (whether in the form of cash, Common Stock, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
        spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the Company’s structure affecting the Common Stock occurs, then in order to prevent dilution or enlargement of the benefits or

    18.2          Dissolution or Liquidation. Unless otherwise determined by the Committee,
        in the event of a proposed dissolution or liquidation of the Company, any Offering Period then in progress shall be shortened by setting a new Purchase Date and the Offering Period shall end immediately before the proposed dissolution or
        liquidation. The new Purchase Date shall be before the date of the Company’s proposed dissolution or liquidation. Before the new Purchase Date, the Committee shall provide each Participant with written notice, which may be electronic, of the new
        Purchase Date and that the Participant’s option shall be exercised automatically on such date, unless before such time, the Participant has withdrawn from the Offering in accordance with Section 10 (or is deemed to have withdrawn in accordance with
        Section 11).

    

    

    18.3          Corporate Transactions. In the event of a Corporate Transaction, the

        provide each Participant with written notice, which may be electronic, of the new Purchase Date and that the Participant’s option shall be exercised automatically on such date, unless before such time, the Participant has withdrawn from the
        Offering in accordance with Section 10 (or is deemed to have withdrawn in accordance with Section 11).

    The Committee may specify in an Award Agreement that a Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of
      certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award.  Such events may include a Termination of Service with or without Cause (and, in the case of any Cause that is resulting from an
      indictment or other non-final determination, the Committee may provide for such Award to be held in escrow or abeyance until a final resolution of the matters related to such event occurs, at which time the Award shall either be reduced, cancelled or
      forfeited (as provided in such Award Agreement) or remain in effect, depending on the outcome), violation of material policies, breach of non-competition, non-solicitation, confidentiality or other restrictive covenants, or requirements to comply
      with minimum share ownership requirements, that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company and/or its Affiliates.

    

    

    Awards shall be subject to the requirements of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (regarding recovery of erroneously awarded compensation) and any implementing rules and
      regulations thereunder.  The Committee shall have the authority to implement any policies and procedures necessary to comply with Section 10D of the Exchange Act and any rules promulgated thereunder and any other regulatory regimes.  Notwithstanding
      anything to the contrary contained herein, any Awards granted under the Plan (including any amounts or benefits arising from such Awards) shall be subject to any clawback or recoupment arrangements or policies the Company has in place from time to
      time, and the Committee may or shall, to the extent permitted or required by applicable law and stock exchange rules or by any applicable Company policy or arrangement, cancel or require reimbursement of or with respect to any Awards granted to the
      Participant or any Shares issued or cash received upon vesting, exercise or settlement of any such Awards or sale of Shares underlying such Awards.

    

    

    3.4.          Deferral Arrangement

      provisions for the payment or crediting of interest or dividend equivalents, including converting such credits into deferred Stock units.

    4.1.          Authorized Number of Shares

    

    

    Subject to adjustment under Section 15 and except for Substitute Awards, the total number of shares of Common Stock authorized to be awarded under the Plan shall not exceed 4,564,508 shares. Shares issued under the Plan
      may consist in whole or in part of authorized but unissued shares, treasury shares, or shares purchased on the open market or otherwise, all as determined by the Company from time to time.

    

    

    4.2.          Share Counting

    

    

    4.2.1.          General

    

    

    Each share of Common Stock granted in connection with an Award shall be counted as one share against the limit in Section 4.1, subject to the provisions of this Section 4.2. Share-based Performance Awards shall be
      counted assuming maximum performance results (if applicable) until such time as actual performance results can be determined.

    

    

    4.2.2.          Cash-Settled Awards

    

    

    Any Award settled in cash shall not be counted as shares of Common Stock for any purpose under this Plan.

    

    

    4.2.3.          Expired or Terminated Awards

    

    

    If any Award (other than a Substitute Award) under the Plan expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued Common Stock covered by such Award shall again be available for the grant
      of Awards under the Plan.

    

    

    4.2.4.          Payment of Option Price or Tax Withholding in Shares

    

    

    If shares of Common Stock issuable upon exercise, vesting or settlement of an Award, or shares of Common Stock owned by a Grantee (which are not subject to any pledge or other security interest), are surrendered or
      tendered to the Company in payment of the Option Price or Purchase Price of an Award or any taxes required to be withheld in respect of an Award, in each case, in accordance with the terms and conditions of the Plan and any applicable Award
      Agreement, such surrendered or tendered shares of Common Stock shall again be available for the grant of Awards under the Plan. For a share-settled SAR, only the net shares actually issued upon exercise of the SAR shall be counted against the limit
      in Section 4.1.

    
      7

      
        

    

    4.2.5.          Substitute Awards

    

    

    In the case of any Substitute Award, such Substitute Award shall not be counted against the number of shares reserved under the Plan; provided that if a Substitute Award under
      the Plan expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued Common Stock covered by such Substitute Award not again be available for the grant of Awards under the Plan.  In no event shall the terms of this Plan
      have the effect of adversely amending the terms of any Substitute Award (it being understood, without limitation of the foregoing, that the definition of Change in Control set forth below shall not apply to the Legacy Aspen Technology Awards, with
      respect to which the consummation of the transactions contemplated by the Transaction Agreement shall constitute a Change in Control under the existing terms of such awards).

    

    

    4.3.          Award Limits

    

    

    4.3.1.          Incentive Stock Options

    4.3.2.          Limits on Awards to Non-Employee Directors

    

    

    No share-based Awards may be granted under the Plan during any one year to a Grantee who is a Non-Employee Director that exceed, together with any cash compensation received for such service, $750,000 (based on the Fair
      Market Value of the shares of Common Stock underlying the Award as of the applicable Grant Date in the case of Restricted Stock, Restricted Stock Units or Other Stock-based Awards, and based on the applicable grant date fair value for accounting
      purposes in the case of Options or SARs).

      may be terminated on any earlier date as provided in Section 5.2.

    

    

    5.2.          Amendment and Termination of the Plan

    

    

    Subject to the Stockholders Agreement, the Board may, at any time and from time to time, amend, suspend, or terminate the Plan as to any Awards which have not been made. An amendment shall be contingent on approval of
      (i) the Company’s shareholders to the extent stated by the Board, required by applicable law or required by applicable stock exchange listing requirements and (ii) Emerson, to the extent required by the Stockholders Agreement. Notwithstanding the
      foregoing, any amendment to Section 3.2 shall be contingent upon the approval of (i) the Company’s shareholders and (ii) to the extent required by the Stockholders Agreement, Emerson. No Awards shall be made after the Termination Date. The applicable
      terms of the Plan, and any terms and conditions applicable to Awards granted prior to the Termination Date shall survive the termination of the Plan and continue to apply to such Awards. No amendment, suspension, or termination of the Plan shall,
      without the consent of the Grantee, materially impair rights or obligations under any Award theretofore awarded.

    6.2.          Successive Awards

    

    

    An eligible person may receive more than one Award, subject to such restrictions as are provided herein.

    

    

    6.3.          Stand-Alone, Additional, Tandem, and Substitute Awards

    

    

    Awards may, in the discretion of the Board, be granted either alone or in addition to, in tandem with, or in substitution or exchange for, any other Award or any award granted under another plan of the Company, any
      Subsidiary, or any business entity to be acquired by the Company or a Subsidiary, or any other right of a Grantee to receive payment from the Company or any Subsidiary. Such additional, tandem, and substitute or exchange Awards may be granted at any
      time. If an Award is granted in substitution or exchange for another Award, the Board shall have the right to require the surrender of such other Award in consideration for the grant of the new Award. Subject to Section 3.2, the Board shall have the
      right, in its discretion, to make Awards in substitution or exchange for any other award under another plan of the Company, any Subsidiary, or any business entity to be acquired by the Company or any Subsidiary. In addition, Awards may be granted in
      lieu of cash compensation, including in lieu of cash amounts payable under other plans of the Company or any Subsidiary, in which the value of Stock subject to the Award is equivalent in value to the cash compensation (for example, Restricted Stock
      Units or Restricted Stock).

    

    

    	7.	
            AWARD AGREEMENT

          

    

    

    Each Award shall be evidenced by an Award Agreement, in such form or forms as the Board shall from time to time determine. Without limiting the foregoing, an Award Agreement may be provided in the form of a notice which
      provides that acceptance of the Award constitutes acceptance of all terms of the Plan and the notice. Award Agreements granted from time to time or at the same time need not contain similar provisions but shall be consistent with the terms of the
      Plan. Each Award Agreement evidencing an Award of Options shall specify whether such Options are intended to be Non-qualified Stock Options or Incentive Stock Options, and in the absence of such specification such options shall be deemed
      Non-qualified Stock Options.

    8.1.          Option Price

    

    

    The Option Price of each Option shall be fixed by the Board and stated in the related Award Agreement. The Option Price of each Option (except those that constitute Substitute Awards) shall be at least the Fair Market
      Value on the Grant Date of a share of Stock; provided, however, that in the event that a Grantee is a Ten Percent Shareholder as of the Grant Date, the Option Price
      of an Option granted to such Grantee that is intended to be an Incentive Stock Option shall be not less than 110 percent of the Fair Market Value of a share of Stock on the Grant Date. In no case shall the Option Price of any Option be less than the
      par value of a share of Stock.

    
      9

      Award Agreement.

      date prior thereto as is set forth in the Plan or as may be fixed by the Board and stated in the related Award Agreement; provided, however, that in the event that
      the Grantee is a Ten Percent Shareholder, an Option granted to such Grantee that is intended to be an Incentive Stock Option at the Grant Date shall not be exercisable after the expiration of five (5) years from its Grant Date.

    

    

    8.4.          Limitations on Exercise of Option

    

    

    Notwithstanding any other provision of the Plan, in no event may any Option be exercised, in whole or in part, after the occurrence of an event which results in termination of the Option.

    

    

    8.5.          Method of Exercise

    

    

    An Option that is exercisable may be exercised by the Grantee’s delivery of a notice of exercise to the Company, setting forth the number of shares of Stock with respect to which the Option is to be exercised, accompanied by full payment for the
      shares. To be effective, notice of exercise must be made in accordance with procedures established by the Company from time to time.

    

    

    8.6.          Rights of Holders of Options

    

    

    Unless otherwise stated in the related Award Agreement, an individual holding or exercising an Option shall have none of the rights of a shareholder (for example, the right to receive cash or dividend payments or
      distributions attributable to the subject shares of Stock or to direct the voting of the subject shares of Stock) until the shares of Stock covered thereby are fully paid and issued to him. Except as provided in Section 15 hereof or the related Award
      Agreement, no adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date of such issuance.

    

    

    8.7.          Limitations on Incentive Stock Options

    

    

    An Option shall constitute an Incentive Stock Option only (i) if the Grantee of such Option is an employee of the Company or any Subsidiary of the Company; (ii) to the extent specifically provided in the related Award
      Agreement; and (iii) to the extent that the aggregate Fair Market Value (determined at the time the Option is granted) of the shares of Stock with respect to which all Incentive Stock Options held by such Grantee become exercisable for the first time
      during any calendar year (under the Plan and all other plans of the Grantee’s employer and its Affiliates) does not exceed $100,000. This limitation shall be applied by taking Options into account in the order in which they were granted.

    

    

    	9.	
            TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS

          

    

    

    9.1.          Right to Payment

    

    

    A SAR shall confer on the Grantee a right to receive, upon exercise thereof, the excess of (i) the Fair Market Value of one share of Stock on the date of exercise over (ii) the SAR Exercise Price, as determined by the
      Board. The Award Agreement for a SAR (except those that constitute Substitute Awards) shall specify the SAR Exercise Price, which shall be fixed on the Grant Date as not less than the Fair Market Value of a share of Stock on that date. SARs may be
      granted alone or in conjunction with all or part of an Option or at any subsequent time during the term of such Option or in conjunction with all or part of any other Award. A SAR granted in tandem with an outstanding Option following the Grant Date
      of such Option shall have a SAR Exercise Price that is equal to the Option Price; provided, however, that the SAR Exercise Price may not be less than the Fair Market
      Value of a share of Stock on the Grant Date of the SAR.

    
      10

      
        

    

    9.2.          Other Terms

    

    

    The Board shall determine at the Grant Date, the time or times at which and the circumstances under which a SAR may be exercised in whole or in part (including based on achievement of performance goals and/or future
      service requirements), the time or times at which SARs shall cease to be or become exercisable following Separation from Service or upon other conditions, the method of exercise, whether or not a SAR shall be in tandem or in combination with any
      other Award, and any other terms and conditions of any SAR.

    

    

    9.3.          Term of SARs

    

    

    The term of a SAR granted under the Plan shall be determined by the Board, in its sole discretion; provided, however, that such term
      shall not exceed ten (10) years.

    

    

    9.4.          Payment of SAR Amount

    

    

    Upon exercise of a SAR, a Grantee shall be entitled to receive payment from the Company (in cash or Stock, as determined by the Board and set forth in the applicable Award Agreement) in an amount determined by
      multiplying:

    

    

    	

          	(i)	
            the difference between the Fair Market Value of a share of Stock on the date of exercise over the SAR Exercise Price; by

          

    

    

    	

          	(ii)	
            the number of shares of Stock with respect to which the SAR is exercised.

    10.1.          Restrictions

    

    

    At the time of grant, the Board may, in its sole discretion, establish a period of time (a “Restricted Period”) and any additional restrictions including the satisfaction of
      corporate or individual performance objectives applicable to an Award of Restricted Stock or Restricted Stock Units in accordance with Section 12. Each Award of Restricted Stock or Restricted Stock Units may be subject to a different Restricted
      Period and additional restrictions. Neither Restricted Stock nor Restricted Stock Units may be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the Restricted Period or prior to the satisfaction of the applicable
      restrictions.

    

    

    10.2.          Restricted Stock Certificates

    

    

    The Company shall issue stock, in the name of each Grantee to whom Restricted Stock has been granted, stock certificates or other evidence of ownership representing the total number of shares of Restricted Stock granted to the Grantee, as soon as
      reasonably practicable after the Grant Date.

    10.4.1.          Settlement of Restricted Stock Units

    

    

    Restricted Stock Units may be settled in cash or Stock, as determined by the Board and set forth in the Award Agreement. The Award Agreement shall also set forth whether the Restricted Stock Units shall be settled (i)
      within the time period specified for “short term deferrals” under Section 409A or (ii) otherwise within the requirements of Section 409A, in which case the Award Agreement shall specify upon which events such Restricted Stock Units shall be settled.

    

    

    10.4.2.          Voting and Dividend Rights

    

    

    Unless otherwise stated in the applicable Award Agreement and subject to Section 17.12, holders of Restricted Stock Units shall not have rights as shareholders of the Company, including no voting or dividend or dividend
      equivalents rights.

    

    

    10.4.3.          Creditor’s Rights

    

    

    A holder of Restricted Stock Units shall have no rights other than those of a general creditor of the Company. Restricted Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms
      and conditions of the applicable Award Agreement.

    

    

    10.5.          Purchase of Restricted Stock

      Stock represented by such Restricted Stock or (ii) the Purchase Price, if any, specified in the related Award Agreement. If specified in the Award Agreement, the Purchase Price may be deemed paid by Services already rendered. If required, the
      Purchase Price shall be payable in a form described in Section 11 or, in the discretion of the Board, in consideration for past Services rendered.

    

    

    10.6.          Delivery of Stock

    

    

    Upon the expiration or termination of any Restricted Period and the satisfaction of any other conditions prescribed by the Board, the restrictions applicable to shares of Restricted Stock or Restricted Stock Units
      settled in Stock shall lapse, and, unless otherwise provided in the Award Agreement and subject to Section 3.6, a stock certificate for such shares shall be delivered, free of all such restrictions, to the Grantee or the Grantee’s beneficiary or
      estate, as the case may be.

    11.1.          General Rule

    

    

    Payment of the Option Price for the shares purchased pursuant to the exercise of an Option or any Purchase Price for Restricted Stock shall be made in cash or in cash equivalents acceptable to the Company, except as
      provided in this Section 11.

    
      12

      
        

    

    11.2.          Surrender of Stock

    

    

    To the extent the Award Agreement so provides, payment of the Option Price for shares purchased pursuant to the exercise of an Option or the Purchase Price for Restricted Stock may be made all or in part through the
      tender to the Company of shares of Stock, which shares shall be valued, for purposes of determining the extent to which the Option Price or Purchase Price for Restricted Stock has been paid thereby, at their Fair Market Value on the date of exercise
      or surrender. Notwithstanding the foregoing, in the case of an Incentive Stock Option, the right to make payment in the form of already owned shares of Stock may be authorized only at the time of grant.

    

    

    11.3.          Cashless Exercise

    

    

    With respect to an Option only (and not with respect to Restricted Stock), to the extent permitted by law and to the extent the Award Agreement so provides, payment of the Option Price may be made all or in part by
      delivery (on a form acceptable to the Company) of an irrevocable direction to a licensed securities broker acceptable to the Company to sell shares of Stock and to deliver all or part of the sales proceeds to the Company in payment of the Option
      Price and any withholding taxes described in Section 17.3, subject to such terms and procedures as determined by the Company.

    

    

    11.4.          Other Forms of Payment

    

    

    To the extent the Award Agreement so provides, payment of the Option Price or the Purchase Price for Restricted Stock may be made in any other form that is consistent with applicable laws, regulations and rules,
      including, but not limited to, the Company’s withholding of shares of Stock otherwise due to the exercising Grantee.

    12.1.          Performance Conditions

    

    

    The right of a Grantee to exercise or receive a grant or settlement of any Award, and the timing thereof, may be subject to such performance conditions as may be specified by the Committee. The Committee may use such
      business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions.

    

    

    12.1.1.          Settlement of Performance Awards; Other Terms

    

    

    Settlement of Performance Awards shall be in cash, Stock, other Awards or other property, in the discretion of the Committee. The Committee may, in its discretion, reduce the amount of a settlement otherwise to be made

    13.1.          Grant of Other Stock-based Awards

    

    

    Other Stock-based Awards may be granted either alone or in addition to or in conjunction with other Awards under the Plan. Other Stock-based Awards may be granted in lieu of other cash or other compensation to which a
      Service Provider is entitled from the Company or may be used in the settlement of amounts payable in shares of Common Stock under any other compensation plan or arrangement of the Company. Subject to the provisions of the Plan, the Committee shall
      have the sole and complete authority to determine the persons to whom and the time or times at which such Awards shall be made, the number of shares of Common Stock to be granted pursuant to such Awards, and all other conditions of such Awards.
      Unless the Committee determines otherwise, any such Award shall be confirmed by an Award Agreement, which shall contain such provisions as the Committee determines to be necessary or appropriate to carry out the intent of this Plan with respect to
      such Award.

    
      13

      
        

    

    13.2.          Terms of Other Stock-based Awards

    

    

    Any Common Stock subject to Awards made under this Section 13 may not be sold, assigned, transferred, pledged or otherwise encumbered prior to the date on which the shares are issued, or, if later, the date on which any
      applicable restriction, performance or deferral period lapses.

            REQUIREMENTS OF LAW

          

    

    

    14.1.          General

    

    

    The Company shall not be required to sell or issue any shares of Stock under any Award if the sale or issuance of such shares would constitute a violation by the Grantee, any other individual exercising an Option, or the
      Company of any provision of any law or regulation of any governmental authority, including without limitation any federal or state securities laws or regulations. If at any time the Company shall determine, in its discretion, that the listing,
      registration or qualification of any shares subject to an Award upon any securities exchange or under any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance or purchase of shares hereunder,
      no shares of Stock may be issued or sold to the Grantee or any other individual exercising an Option pursuant to such Award unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any
      conditions not acceptable to the Company, and any delay caused thereby shall in no way affect the date of termination of the Award. Specifically, in connection with the Securities Act, upon the exercise of any Option or the delivery of any shares of
      Stock underlying an Award, unless a registration statement under such Act is in effect with respect to the shares of Stock covered by such Award, the Company shall not be required to sell or issue such shares unless the Board has received evidence
      satisfactory to it that the Grantee or any other individual exercising an Option may acquire such shares pursuant to an exemption from registration under the Securities Act. Any determination in this connection by the Board shall be final, binding,
      and conclusive. The Company may, but shall in no event be obligated to, register any securities covered hereby pursuant to the Securities Act. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an
      Option or the issuance of shares of Stock pursuant to the Plan to comply with any law or regulation of any governmental authority. As to any jurisdiction that expressly imposes the requirement that an Option shall not be exercisable until the shares
      of Stock covered by such Option are registered or are exempt from registration, the exercise of such Option (under circumstances in which the laws of such jurisdiction apply) shall be deemed conditioned upon the effectiveness of such registration or
      the availability of such an exemption.

    

    

    14.2.          Rule 16b-3

    

    

    During any time when the Company has a class of equity security registered under Section 12 of the Exchange Act, it is the intent of the Company that Awards and the exercise of Options granted to officers and directors
      hereunder will qualify for the exemption provided by Rule 16b-3 under the Exchange Act.  In the event that Rule 16b-3 is revised or replaced, the Board may exercise its discretion to modify this Plan in any respect necessary to satisfy the
      requirements of, or to take advantage of any features of, the revised exemption or its replacement.

    	15.	
            EFFECT OF CHANGES IN CAPITALIZATION

          

    

    

    15.1.          Changes in Stock

    

    

    Following the closing of the transactions contemplated by the Transaction Agreement, if (i) the number of outstanding shares of Stock is increased or decreased or the shares of Stock are changed into or exchanged for a
      different number or kind of shares or other securities of the Company on account of any recapitalization, reclassification, stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital
      stock, or other increase or decrease in such shares is effected without receipt of consideration by the Company or (ii) there occurs any spin-off, split-up, extraordinary cash dividend or other distribution of assets by the Company, the number and
      kinds of shares for which grants of Awards may be made under the Plan shall be equitably adjusted by the Company; provided that any such adjustment shall comply with Section 409A. In addition, in the event of any such increase or decrease in the
      number of outstanding shares as described in clause (i) above or other transaction described in clause (ii) above, the number and kind of shares for which Awards are outstanding and the Option Price per share of outstanding Options and SAR Exercise
      Price per share of outstanding SARs shall be equitably adjusted; provided that any such adjustment shall comply with Section 409A.

    

    

    15.2.          Effect of Certain Transactions

    

    

    Except as otherwise provided in an Award Agreement, in the event of a Corporate Transaction, the Plan and the Awards issued hereunder shall continue in effect in accordance with their respective terms, except that
      following a Corporate Transaction either (i) each outstanding Award shall be treated as provided for in the agreement entered into in connection with the Corporate Transaction or (ii) if not so provided in such agreement, each Grantee shall be
      entitled to receive in respect of each share of Common Stock subject to any outstanding Awards, upon exercise or payment or transfer in respect of any Award, the same number and kind of stock, securities, cash, property or other consideration that
      each holder of a share of Common Stock was entitled to receive in the Corporate Transaction in respect of a share of Common Stock; provided, however, that, in the
      case of (ii), unless otherwise determined by the Committee, such stock, securities, cash, property or other consideration shall remain subject to all of the conditions, restrictions and performance criteria which were applicable to the Awards prior
      to such Corporate Transaction. Without limiting the generality of the foregoing, the treatment of outstanding Options and SARs pursuant to this Section 15.2 in connection with a Corporate Transaction in which the consideration paid or distributed to
      the Company’s shareholders is not entirely shares of common stock of the acquiring or resulting corporation may include the cancellation of outstanding Options and SARs upon consummation of the Corporate Transaction as long as, at the election of the
      Committee, (i) the holders of affected Options and SARs have been given a specified period (as determined by the Committee) prior to the date of the consummation of the Corporate Transaction to exercise the Options or SARs (to the extent otherwise
      exercisable) or (ii) the holders of the affected Options and SARs are paid (in cash or cash equivalents) in respect of each Share covered by the Option or SAR being canceled an amount equal to the excess, if any, of the per share price paid or
      distributed to shareholders in the Corporate Transaction (the value of any non-cash consideration to be determined by the Committee in its sole discretion) over the Option Price or SAR Exercise Price, as applicable. For avoidance of doubt, (1) the
      cancellation of Options and SARs pursuant to clause (ii) of the preceding sentence may be effected notwithstanding anything to the contrary contained in this Plan or any Award Agreement and (2) if the amount determined pursuant to clause (ii) of the
      preceding sentence is zero or less, the affected Option or SAR may be cancelled without any payment therefore. The treatment of any Award as provided in this Section 15.2 shall be conclusively presumed to be appropriate for purposes of Section 15.1.

    
      15

      
        

    

    15.3.          Change in Control

    

    

    15.3.1.          Consequences of a Change in Control

    

    

    For any Awards outstanding as of the date of a Change in Control (but not for Legacy Aspen Technology Awards, which shall continue to be governed by their pre-existing terms, including those with respect to the effect of
      a Change in Control and subject to the Transaction Agreement), either of the following provisions shall apply, depending on whether, and the extent to which, Awards are assumed, converted or replaced by the resulting entity in a Change in Control,
      unless otherwise provided by the Award Agreement or determined by the Committee:

    

    

    	

          	(i)	
            To the extent such Awards are not assumed, converted or replaced by the resulting entity in the Change in Control, then upon the Change in Control such outstanding Awards that may be exercised shall become fully
              exercisable, all restrictions with respect to such outstanding Awards, other than for Performance Awards, shall lapse and become vested and non-forfeitable, and for any outstanding Performance Awards the payout opportunities attainable under
              such Awards shall be deemed to have been fully earned as of the Change in Control based upon the greater of: (A) an assumed achievement of all relevant performance goals at the “target” level, or (B) the actual level of achievement of all
              relevant performance goals against target as of the Company’s fiscal quarter end preceding the Change in Control and the Award shall become vested pro rata based on the portion of the applicable performance period completed through the date
              of the Change in Control.

          

    

    

    	

          	(ii)	
            To the extent such Awards are 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 Service Provider has a Separation from
              Service by the Company other than for “cause” (which may include a Separation from Service by the Service Provider for “good reason” if provided in the applicable Award Agreement), as such terms are defined in the Award Agreement, then such
              outstanding Awards that may be exercised shall become fully exercisable, all restrictions with respect to such outstanding Awards, other than for Performance Awards, shall lapse and become vested and non-forfeitable, and for any outstanding
              Performance Awards the payout opportunities attainable under such Awards shall be deemed to have been fully earned as of the Separation from Service based upon the greater of: (A) an assumed achievement of all relevant performance goals at
              the “target” level, or (B) the actual level of achievement of all relevant performance goals against target as of the Company’s fiscal quarter end preceding the Change in Control and the Award shall become vested pro rata based on the portion
              of the applicable performance period completed through the date of the Separation from Service.

          

    

    

    15.3.2.          Change in Control Defined

    

    

    A “Change in Control” shall mean the occurrence of any of the following events:

    

    

    	

          	(i)	
            the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership of any capital
              stock of the Company if, as a result of such acquisition, such Person becomes the beneficial owner (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of either (x) the then-outstanding shares of common stock
              of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the then-outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided that for purposes of this subsection (i), the following acquisitions of capital stock of the Company shall not constitute a Change in Control: (A) any
              acquisition directly from the Company (excluding an acquisition pursuant to the exercise, conversion or exchange of any security exercisable for, convertible into or exchangeable for common stock or voting securities of the Company, unless
              the Person exercising, converting or exchanging such security acquired such security directly from the Company or an underwriter or agent of the Company), (B) any acquisition by any employee benefit plan (or related trust) sponsored or
              maintained by the Company or any corporation controlled by the Company or (C) any acquisition by any corporation pursuant to a Business Combination (as defined in subsection (iii) of this Section 15.3.2) that complies with clauses (x) and (y)
              of subsection (iii) of this Section 15.3.2 or (D) any acquisition by Emerson or its Affiliates (as described in the Stockholders Agreement); or

          

    
      16

      
        

    

    	

          	(ii)	
            such time as the Continuing Directors do not constitute a majority of the Board (or, if applicable, the Board of Directors of a successor corporation to the Company), where the term “Continuing

                Director” means at any date a member of the Board (x) who was a member of the Board immediately following the consummation of the transactions contemplated by the Transaction Agreement or (y) who was nominated or elected subsequent
              to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or endorsed by at least a majority of the directors who were
              Continuing Directors at the time of such nomination or election or who was nominated or elected pursuant to the Stockholders Agreement, provided that there shall be excluded from this clause (y) any individual whose initial assumption of
              office occurred as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents, by or on behalf of a Person other than the Board;
              provided that this clause (ii) shall not apply for so long as Emerson beneficially owns a majority of the outstanding shares of Common Stock or has a right to nominate a majority of the members of the
              Board pursuant to the Stockholders Agreement; or

          

    

    

    	

          	(iii)	
            the consummation of a merger, amalgamation, consolidation, reorganization, recapitalization or share exchange involving the Company or a sale or other disposition of all or substantially all of the assets of the
              Company (a “Business Combination”), unless, either (A) immediately following such Business Combination, each of the following two conditions is satisfied: (x) all or substantially all of the individuals
              and entities who were the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the
              then-outstanding shares of common stock and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors, respectively, of the resulting or acquiring corporation in such Business
              Combination (which shall include a corporation that as a result of such transaction owns the Company or substantially all of the Company’s assets either directly or through one or more subsidiaries) (such resulting or acquiring corporation is
              referred to herein as the “Acquiring Corporation”) in substantially the same proportions as their ownership of the Outstanding Company Common Stock and Outstanding Company Voting Securities,
              respectively, immediately prior to such Business Combination, excluding for all purposes of this clause (x) any shares of common stock or other securities of the Acquiring Corporation attributable to any such individual’s or entity’s
              ownership of securities other than Outstanding Company Common Stock or Outstanding Company Voting Securities immediately prior to the Business Combination); and (y) no Person (excluding the Acquiring Corporation or any employee benefit plan
              (or related trust) maintained or sponsored by the Company or by the Acquiring Corporation) beneficially owns, directly or indirectly, 50% or more of the then-outstanding shares of common stock of the Acquiring Corporation, or of the combined
              voting power of the then-outstanding securities of such corporation entitled to vote generally in the election of directors (except to the extent that such ownership existed prior to the Business Combination) or (B) such Business Combination
              is with Emerson or one of its Affiliates (as defined in the Stockholders Agreement); or

          

    
      17

      
        

    

    	

          	(iv)	
            the liquidation or dissolution of the Company.

          

    

    

    For the avoidance of doubt and notwithstanding anything to the contrary herein, the consummation of the transactions contemplated by the Transaction Agreement shall not constitute a Change in Control
      (it being understood that the transactions contemplated by the Transaction Agreement shall constitute a Change in Control with respect to the Legacy Aspen Technology Awards under the existing terms of such awards).

    

    

    15.4.          Adjustments

    

    

    Adjustments under this Section 15 related to shares of Stock or securities of the Company shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. No fractional shares or
      other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share.

    

    

    	16.	
            NO LIMITATIONS ON COMPANY

          

    

    

    The making of Awards pursuant to the Plan shall not affect or limit in any way the right or power of the Company to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure or
      to merge, consolidate, dissolve, or liquidate, or to sell or transfer all or any part of its business or assets.

    

    

    	17.	
            TERMS APPLICABLE GENERALLY TO AWARDS GRANTED UNDER THE PLAN

          

    

    

    17.1.          Disclaimer of Rights

    

    

    No provision in the Plan or in any Award Agreement shall be construed to confer upon any individual the right to remain in the employ or service of the Company or any Subsidiary, or to interfere in any way with any
      contractual or other right or authority of the Company either to increase or decrease the compensation or other payments to any individual at any time, or to terminate any employment or other relationship between any individual and the Company. In
      addition, notwithstanding anything contained in the Plan to the contrary, unless otherwise stated in the applicable Award Agreement, no Award granted under the Plan shall be affected by any change of duties or position of the Grantee, so long as such
      Grantee continues to be a Service Provider. The obligation of the Company to pay any benefits pursuant to this Plan shall be interpreted as a contractual obligation to pay only those amounts described herein, in the manner and under the conditions
      prescribed herein. The Plan shall in no way be interpreted to require the Company to transfer any amounts to a third party trustee or otherwise hold any amounts in trust or escrow for payment to any Grantee or beneficiary under the terms of the Plan.

    
      18

      
        

    

    17.2.          Nonexclusivity of the Plan

    

    

    Neither the adoption of the Plan nor the submission of the Plan to the shareholders of the Company for approval shall be construed as creating any limitations upon the right and authority of the Board to adopt such other
      incentive compensation arrangements (which arrangements may be applicable either generally to a class or classes of individuals or specifically to a particular individual or particular individuals), including, without limitation, the granting of
      stock options as the Board in its discretion determines desirable.

    

    

    17.3.          Withholding Taxes

    

    

    The Company or a Subsidiary, as the case may be, shall have the right to deduct from payments of any kind otherwise due to a Grantee any federal, state, or local taxes of any kind required by law to be withheld (i) with
      respect to the vesting of or other lapse of restrictions applicable to an Award, (ii) upon the issuance of any shares of Stock upon the exercise of an Option or SAR, or (iii) otherwise due in connection with an Award. At the time of such vesting,
      lapse, or exercise, the Grantee shall pay to the Company or the Subsidiary, as the case may be, any amount that the Company or the Subsidiary may reasonably determine to be necessary to satisfy such withholding obligation. The Company or the
      Subsidiary, as the case may be, may in its sole discretion, require or permit the Grantee to satisfy such obligations, in whole or in part, (a) by causing the Company or the Subsidiary to withhold the up to the maximum required number of shares of
      Stock otherwise issuable to the Grantee as may be necessary to satisfy such withholding obligation, (b) by delivering to the Company or the Subsidiary shares of Stock already owned by the Grantee or (c) through a “sell-to-cover” arrangement (subject
      to such terms and procedures determined by the Committee). The shares of Stock so delivered or withheld shall have an aggregate Fair Market Value equal to such withholding obligations. The Fair Market Value of the shares of Stock used to satisfy such
      withholding obligation shall be determined by the Company or the Subsidiary as of the date that the amount of tax to be withheld is to be determined. To the extent applicable, a Grantee may satisfy his or her withholding obligation only with shares
      of Stock that are not subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements.

    

    

    17.4.          Captions

    

    

    The use of captions in this Plan or any Award Agreement is for the convenience of reference only and shall not affect the meaning of any provision of the Plan or any Award Agreement.

    

    

    17.5.          Other Provisions

    

    

    Each Award Agreement may contain such other terms and conditions not inconsistent with the Plan as may be determined by the Board, in its sole discretion. In the event of any conflict between the terms of an employment
      agreement and the Plan, the terms of the employment agreement govern.

    

    

    17.6.          Number and Gender

    

    

    With respect to words used in this Plan, the singular form shall include the plural form, the masculine gender shall include the feminine gender, etc., as the context requires.

    

    

    17.7.          Severability

    

    

    If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their
      terms, and all provisions shall remain enforceable in any other jurisdiction.

    
      19

      
        

    

    17.8.          Governing Law

    

    

    The Plan shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to the principles of conflicts of law, and applicable Federal law.

    

    

    17.9.          Section 409A

    

    

    The Plan and Awards made hereunder are intended to comply with Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and administered to be in
      compliance therewith. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless applicable laws require otherwise. Notwithstanding anything
      to the contrary in the Plan, to the extent required to avoid accelerated taxation and tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to the Plan during the six (6)
      month period immediately following the Grantee’s Separation from Service shall instead be paid on the first payroll date after the six-month anniversary of the Grantee’s Separation from Service (or the Grantee’s death, if earlier). Notwithstanding
      the foregoing, neither the Company nor the Committee shall have any obligation to take any action to prevent the assessment of any excise tax or penalty on any Grantee under Section 409A and neither the Company nor the Committee will have any
      liability to any Grantee for such tax or penalty.

    

    

    17.10.          Separation from Service

    

    

    The Board shall determine the effect of a Separation from Service upon Awards, and such effect shall be set forth in the appropriate Award Agreement. Without limiting the foregoing, the Board may provide in the Award
      Agreements at the time of grant, or any time thereafter with the consent of the Grantee, the actions that will be taken upon the occurrence of a Separation from Service, including, but not limited to, accelerated vesting or termination, depending
      upon the circumstances surrounding the Separation from Service.

    

    

    17.11.          Transferability of Awards

    

    

    17.11.1.          Transfers in General

    

    

    Except as provided in Section 17.11.2, no Award shall be assignable or transferable by the Grantee to whom it is granted, other than by will or the laws of descent and distribution, and, during the lifetime of the
      Grantee, only the Grantee personally (or the Grantee’s personal representative) may exercise rights under the Plan.

    

    

    17.11.2.          Family Transfers

    

    

    If authorized in the applicable Award Agreement or thereafter by the Committee, a Grantee may transfer, not for value, all or part of an Award (other than Incentive Stock Options) to any Family Member. For the purpose of
      this Section 17.11.2, a “not for value” transfer is a transfer which is (i) a gift, (ii) a transfer under a domestic relations order in settlement of marital property rights; or (iii) a transfer to an entity in which more than fifty percent of the
      voting interests are owned by Family Members (or the Grantee) in exchange for an interest in that entity. Following a transfer under this Section 17.11.2, any such Award shall continue to be subject to the same terms and conditions as were applicable
      immediately prior to transfer. Subsequent transfers of transferred Awards are prohibited except to Family Members of the original Grantee in accordance with this Section 17.11.2 or by will or the laws of descent and distribution.

    
      20

      
        

    

    17.12.          Dividends and Dividend Equivalent Rights

    

    

    If specified in the Award Agreement, the recipient of an Award under this Plan may be entitled to receive, currently or on a deferred basis, dividends or dividend equivalents with respect to the Common Stock or other
      securities covered by an Award. The terms and conditions of a dividend equivalent right may be set forth in the Award Agreement. Dividend equivalents credited to a Grantee may be paid currently or may be deemed to be reinvested in additional shares
      of Stock or other securities of the Company at a price per unit equal to the Fair Market Value of a share of Stock on the date that such dividend was paid to shareholders, as determined in the sole discretion of the Committee. Notwithstanding the
      foregoing, in no event will dividends or dividend equivalents on any Award which is subject to the achievement of performance criteria be payable before the Award has become earned and payable.

    

    

    17.13.          Data Protection

    

    

    In connection with the Plan, the Company may need to process personal data provided by the Participant to the Company or its Affiliates, third party service providers or others acting on the Company’s behalf. Examples of
      such personal data may include, without limitation, the Participant’s name, account information, social security number, tax number and contact information.  The Company may process such personal data in its legitimate business interests for all
      purposes relating to the operation and performance of the Plan, including but not limited to:

    

    

    (a)          administering and maintaining Participant records;

    

    

    (b)          providing the services described in the Plan;

    

    

    (c)          providing information to future purchasers or merger partners of the Company or any Affiliate, or the business in which such Participant works; and

    

    

    (d)          responding to public authorities, court orders and legal investigations, as applicable.

    

    

    The Company may share the Participant’s personal data with (i) Affiliates, (ii) trustees of any employee benefit trust, (iii) registrars, (iv) brokers, (v) third party administrators of the Plan, (vi) third party service
      providers acting on the Company’s behalf to provide the services described above or (vii) regulators and others, as required by law.

    

    

    If necessary, the Company may transfer the Participant’s personal data to any of the parties mentioned above in a country or territory that may not provide the same protection for the information as the Participant’s
      home country. Any transfer of the Participant’s personal data to recipients in a third country will be made subject to appropriate safeguards or applicable derogations provided for under applicable law.

    

    

    The Company will keep personal data collected in connection with the Plan for as long as necessary to operate the Plan or as necessary to comply with any legal or regulatory requirements.
