PROJECT CROWFOOT INCENTIVE PROGRAM 

AS AMENDED AND RESTATED ON 

AUGUST 13, 2008, OCTOBER 15, 2008 AND MARCH 23, 2010 

The program described herein (the “Program”) is established pursuant to Section 6(e) of ADA-ES, Inc.’s (the
“Company”) 2007 Equity Incentive Plan (the “Plan”). 
 Establishment of
the Program. The Administrator1 hereby establishes the
Program for the purpose of reserving shares and granting Awards to the grantees named herein (each a “Grantee” and collectively the “Grantees”), to incent and reward them for their work for the Company in reaching
certain defined milestones (the “Milestones”) in connection with the development and putting into commercial operation of the Company’s planned “Greenfield” activated carbon (“AC”) manufacturing
facility, which the Company refers to as “Project Crowfoot.” 
 Shares Reserved. There is hereby
reserved within the Plan a total of 172,500 shares of restricted Company common stock (the “Shares”) for awards to be issued in accordance with the terms hereof, to Grantees, as follows: 

Michael Durham (57,500 Shares); 

Mark McKinnies (46,000 Shares); 

Jean Bustard (46,000 Shares); 

Richard Miller (11,500 Shares); and 

Jim Kelly (11,500 Shares); 
 to
be awarded in the discretion of the Administrator in accordance with the terms hereof, with reverse vesting in accordance with the schedule (“Vesting Schedule”) set forth herein, and in accordance with the Plan. 

Limitation on Awards. Section 6(f) of the Plan sets forth the maximum number of Shares which may underlie Awards made to any
individual grantee under the Plan in any fiscal year (the “Individual Annual Plan Maximum”). As of the date of the Program, the Individual Annual Plan Maximum is 30,000. During any fiscal year, the Shares awarded to a Grantee under
the Program shall be such as shall assure that all Awards made to any Grantee for that year under the Plan shall not exceed the Individual Annual Plan Maximum, as the same may be amended from time to time in the future. 

Awards to Grantees Durham, McKinnies and Bustard. In the sole discretion of the Administrator, and subject to the other
requirements set forth herein, Durham, McKinnies and Bustard (i.e., those Grantees for whom more than 30,000 Shares are reserved under the Program) shall be awarded Shares in the following manner: in FY2008, they shall each be awarded Shares
in the amount of the Individual Annual Plan Maximum less the number of other Shares underlying Awards previously granted to them under the Plan in FY2008; in FY2009 and in any subsequent fiscal year, they shall each receive that number of Shares
equal to any remaining Shares reserved for them under the Program but not more than the Individual Annual Plan Maximum less the number of Shares underlying Awards previously granted to them under the Plan in that fiscal year. In the sole discretion
of the Administrator, Shares shall be awarded annually (at the first regular meeting of the Administrator occurring in a fiscal year) to each Grantee in this manner, subject to the other requirements of the Program, until all Shares reserved under
the Program have been awarded to such Grantees.

 The terms “Administrator,” “Awards,” “Grantees” and “Shares” shall each have the meaning given to them in the Plan. 

Amended & Restated Project Crowfoot Incentive Program under the 

ADA-ES, Inc. 2007 Equity Incentive Plan 

 Exhibit 10.70 to Form 10-Q for the quarterly period ended March 31, 2010, filed by ADA-ES, Inc.

 ## indicates portions of the exhibit that have been omitted pursuant to a request for
confidential information and filed separately with the Commission. 
  

 Awards to Grantees Miller and Kelly. In the sole discretion of the Administrator,
and subject to the other requirements set forth herein, Miller and Kelly shall be awarded Shares in an amount up to the number of Shares reserved for them under the Program, but not more than the Individual Annual Plan Maximum less the number of
Shares underlying Awards previously granted to them under the Plan in that fiscal year. In the event the total number of Shares reserved for either Grantee Miller or Kelly cannot be awarded in the first year, Shares shall be awarded in subsequent
years, in the same manner and subject to the same conditions as Awards to be made to Grantees Durham, McKinnies and Bustard. 

Conditions to be Met by Grantee at Time of Award. Each Grantee shall meet all conditions required of a grantee under the Plan at
the time of any Award hereunder. In addition, as of such time, each Grantee shall meet the following additional conditions: (1) Grantee must be meaningfully involved in Project Crowfoot in some capacity; and (2) Grantee must be employed
by, or contracted with, the Company or one of its subsidiaries. Notwithstanding the satisfaction of the foregoing conditions, the Administrator may, in its sole discretion, determine not to make an Award to a Grantee hereunder for any reason, and
Grantee shall have no claim against the Company or the Administrator for the Shares that would have otherwise been the subject of an Award hereunder. 

Awards of Shares under the Program are illustrated in the following table:

 For each fiscal year, the number of Shares awarded under the Program to any Grantee may not exceed the Individual Annual Plan Maximum less the number of shares underlying other Awards
previously granted to that Grantee under the Plan during that fiscal year. This Table, which is for illustrative purposes, shows only Awards made through 2010. However, depending on the number of reserved Shares awarded in prior years, in the
discretion of the Administrator, Awards under the Program may be made beyond 2010. 

3
 For purposes of this table, it is assumed that the Awards for Grantees Miller and Kelly can be made in their entirety in FY 2008 without exceeding the Individual Annual Plan Maximum, and
will therefore be made in their entirety in FY 2008. In no event however, shall the Award of Shares to either of them hereunder be made in an amount which exceeds the Individual Annual Plan Maximum, and any Award hereunder shall be reduced in such a
manner as to assure compliance with this requirement.

Execution of Restricted Stock Agreements. Each Grantee shall timely enter into a Restricted Stock Purchase Agreement (the
“RSPA Agreement”) in the form substantially as attached hereto, as required under the Plan, as to those Shares accepted by the Grantee as an Award hereunder. 

Purchase of Shares by Grantees; Lapse of Company’s Repurchase Rights. Shares awarded hereunder shall be purchased by the
Grantees for the cash purchase price of $.01 per Share. The Shares shall remain the property of the Grantee in accordance with the Plan, subject at all times to the Company’s repurchase rights under the RSPA Agreement which may be exercised in
accordance with the terms of the RSPA Agreement until such time as the Shares vest in accordance with the provisions of the Plan, the RSPA Agreement and the Program. 

Vesting of Shares. The repurchase rights of the Company shall lapse with respect to that percentage of the total Shares reserved
for the Grantee hereunder according to the Vesting Schedule below, following the occurrence of a specific Milestone, so long as the following conditions are met by the Grantee at the time of vesting: (1) Grantee remains meaningfully involved in
Project Crowfoot; and (2) Grantee remains employed by, or contracted with, the Company or one of its subsidiaries. Following the occurrence of a Milestone and as of the next open trading window for the Company’s stock in accordance with
the Company’s insider trading policy, the Shares attributable to that Milestone shall vest, and the Company’s repurchase rights shall lapse, as of such date (the “Vesting Date”).

 If a Milestone is met, and vesting for that Milestone thereafter occurs, but less than that number of Shares has theretofore been granted to the Grantee, then the balance of Shares vested

Request to Exchange Vested Shares for Cash. In order to assist the Grantee with minimum statutory withholding obligations that may
be owing at the time of vesting of the Shares, the Company shall have the option, at the request of the Grantee, to repurchase that portion of the Shares (up to 35% of the Shares vesting at the time of a Vesting Event) necessary to satisfy the
minimum statutory withholding obligation of the Grantee, for an amount equal to the Fair Market Value (as such term is defined in the Plan) of the Shares to be so purchased, as of the Vesting Date. The Grantee shall notify the Company in writing as
to his or her request, including therein a statement as to the number of Shares requested to be repurchased by the Company, not later than 10 days after the Vesting Date of each Milestone and the Company will promptly thereafter inform the Grantee
whether it elects to make such repurchase. If and to the extent the Company agrees to repurchase any of such Shares, the Grantee shall promptly transfer the Shares to be so purchased to the Company and the Company will pay the minimum statutory
withholding obligations to the appropriate authorities.

(As Amended and Restated on August 13, 2008 and October 15, 2008) 

Exhibit 1 

Milestone Definitions 
  

	 	1.	Strategic Partner Plus Promote – This Milestone shall be deemed satisfied as of the date on which the Company enters into a binding, definitive agreement
with a strategic partner for Project Crowfoot by which the partner commits to contribute no less than $60 million of equity to the project and, as part of that agreement, or in an agreement whereby the partner agrees to purchase an equity interest
in the Company, commits to pay the Company no less than One Million Dollars ($1,000,000) in recognition of the advancement of the project to date (or for any other reason). The total amount of this incentive decreases by 5% of the Shares reserved
for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after April 30, 2008, during which this Milestone remains unfulfilled**. 

 

	 	2.	Off-Take Contracts – This Milestone shall be deemed satisfied as of the date on which the Company has entered into definitive contracts which provide for
the sale of a total 200 million pounds of AC over a period of no more than ten (10) years, with pricing within the range set forth in the financial model for the project as of the time of Financial Close (as defined in Milestone #3). The
total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after Financial Close (as defined in Milestone #3), during which this
Milestone remains unfulfilled**. 

  

	 	3.	Financial Close – This Milestone shall be deemed satisfied as of the date on which the Company has entered into definitive contracts which provide for the
date on which debt financing sufficient to assure construction of the first facility (including all items necessary to complete the facility and the first AC production line) is irrevocably committed, subject only to customary funding conditions.
The total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after ##, during which this Milestone remains unfulfilled**.

  

	 	4.	Project Schedule – Plant Start Up – This Milestone shall be deemed satisfied as of the date on which the first production line in the facility is
placed into commercial service with an output capacity of no less than ## pounds of AC per year. The total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of
each monthly anniversary after ##, during which this Milestone remains unfulfilled**

(File No. 000-50216) on May 14, 2010 
 ## indicates portions of the exhibit that have been omitted pursuant to a request for
confidential information and filed separately with the Commission. 
  

	 	5.	Commercial Production/Profitability – This Milestone shall be deemed satisfied as of the date, which shall be no sooner than one year after Plant Start Up
(as defined in Milestone #4), when for a six month average consecutive period, the plant has produced AC with an output capacity of greater than ## pounds of AC per year, at a cost that is within 10% of budgeted operating cost per the financial
model in effect as of Financial Close (as defined in Milestone #3). The total amount of this incentive decreases by 5% of the Shares reserved for the Grantee entitled to such Shares for this Milestone* per month as of each monthly anniversary after
## during which this Milestone remains unfulfilled**. 

 With respect to Shares awarded to Executives other than Mr. Miller:

 *, **   If a Milestone is unfulfilled as of a particular date resulting in a decrease in the amount of an incentive for a certain
Milestone, the number of Shares otherwise allocated to such Milestone resulting from such decrease shall be reallocated to the next Milestone until the Share cap for such Milestone is reached. Such reallocation shall automatically take place as of
the beginning of the day immediately following the deadline for each Milestone that remains unfulfilled. For example, as of July 1, 2008, the “Strategic Partner Plus Promote” Milestone had not been fulfilled, resulting in a decrease
in the number of Shares reserved for each Grantee for such Milestone in the amount of 10% total. Accordingly, as of July 1, the Shares would be reallocated as shown on the attached Schedule 1. Once the Share caps for every Milestone are
reached, any Shares that would have otherwise been re-allocated shall be forfeited and permanently restricted from vesting, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter, notwithstanding anything to
the contrary in the RSPA or the Plan. 
 With respect to Shares awarded to Messrs. Miller and Kelly: 

* For clarification purposes, the parties acknowledge that the failure to achieve a milestone within twenty (20) months after the initial date
specified for the Milestone will divest the Grantee to all rights to the Shares to have vested for attainment of that Milestone. 
 ** If a
Milestone is unfulfilled as of a particular date, thereby leading to a forfeiture of the percentage of Shares specified in the Milestone, the Shares representing that percentage so forfeited shall be permanently restricted from vesting with the
Grantee, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter, notwithstanding any contrary provision of the RSPA or the Plan.

PROJECT CROWFOOT INCENTIVE PROGRAM 

RESTRICTED STOCK PURCHASE AWARD AGREEMENT 

1.     Purchase of Shares. ADA-ES INC., a Colorado corporation (the “Company”), hereby issues
and sells to the Grantee (the “Grantee”) named in the Notice of Restricted Stock Purchase Award (the “Notice”), the Total Number of Shares of Common Stock Awarded set forth in the Notice (the
“Shares”) for a Purchase Price per Share set forth in the Notice (the “Total Purchase Price”), subject to the Notice, this Restricted Stock Purchase Award Agreement (the “Agreement”), the terms and
provisions of the Company’s 2007 Equity Incentive Plan, as amended from time to time (the “Plan”) and the terms and provisions of the Project Crowfoot Incentive Program, as amended and restated on August 13, 2008 and
October 15, 2008 (the “Program”), which are incorporated herein by reference. Payment for the Shares in the amount of the Total Purchase Price set forth in the Notice shall be made to the Company upon execution of the Notice.
Unless otherwise defined herein, the terms defined in the Plan shall have the same defined meanings in this Agreement. All Shares sold hereunder will be deemed issued to the Grantee as fully paid and nonassessable shares, and the Grantee will have
the right to vote the Shares at meetings of the Company’s shareholders. The Company shall pay any applicable stock transfer taxes imposed upon the issuance of the Shares to the Grantee hereunder. 

2.     Method of Payment. Payment of the Total Purchase Price shall be by any of the following, or a
combination thereof, at the election of the Grantee; provided, however, that such payment method does not then violate an Applicable Law: 
  

	 	(a)	cash; or 

  

	 	(b)	check. 

3.     Transfer Restrictions. The Shares sold to the Grantee hereunder may not be sold, transferred by gift,
pledged, hypothecated, or otherwise transferred or disposed of by the Grantee prior to the date when the Shares become vested pursuant to the Vesting Schedule set forth in the Notice. Any attempt to transfer Restricted Shares in violation of this
Section 3 will be null and void and will be disregarded. Before the Shares fully vest, the Shares will be subject to the Company’s Repurchase Rights as set forth in Section 8 below. 

4.     Escrow of Stock. For purposes of facilitating the enforcement of the provisions of this
Agreement, the Grantee agrees, immediately upon receipt of the certificate(s) for the Restricted Shares, to deliver such certificate(s), together with an Assignment Separate from Certificate in the form attached hereto as Exhibit A,
executed in blank by the Grantee and the Grantee’s spouse

(if required for transfer) with respect to each such stock certificate, to the Secretary or Assistant Secretary of the Company, or their designee, to hold in escrow for so long as such Restricted
Shares have not vested pursuant to the Vesting Schedule set forth in the Notice and continue to be subject to the Company’s Repurchase Rights, with the authority to take all such actions and to effectuate all such transfers and/or releases as
may be necessary or appropriate to accomplish the objectives of this Agreement in accordance with the terms hereof. The Grantee hereby acknowledges that the appointment of the Secretary or Assistant Secretary of the Company (or their designee) as
the escrow holder hereunder with the stated authorities is a material inducement to the Company to make this Agreement and that such appointment is coupled with an interest and is accordingly irrevocable. The Grantee agrees that such escrow holder
shall not be liable to any party hereto (or to any other party) for any actions or omissions unless such escrow holder is grossly negligent relative thereto. The escrow holder may rely upon any letter, notice or other document executed by any
signature purported to be genuine and may resign at any time. Upon the vesting of all Restricted Shares and termination of the Company’s Repurchase Right, the escrow holder will, without further order or instruction, transmit to the Grantee the
certificate evidencing such Shares, subject, however, to satisfaction of any withholding obligations provided in Section 6 below. 

5.     Distributions. Except as set forth in Section 8(e), the Company shall disburse to the Grantee all
dividends and other distributions paid or made in cash with respect to the Shares and Additional Securities (whether vested or not), less any applicable withholding obligations. 

6.     Section 83(b) Election and Withholding of Taxes. The Grantee shall provide the Administrator with
a copy of any timely election made pursuant to Section 83(b) of the Internal Revenue Code or similar provision of state law (collectively, an “83(b) Election”), a form of which is attached hereto as Exhibit B. If
the Grantee makes a timely 83(b) Election, the Grantee shall immediately pay the Company the amount necessary to satisfy any applicable foreign, federal, state, and local income and employment tax withholding obligations. If the Grantee does not

income and employment tax withholding obligations. The Grantee may satisfy his or her withholding obligations by authorizing the Company to transfer to the Company the number of vested Shares held in escrow that have an aggregate Fair Market Value
equal to the withholding obligations. The Grantee hereby represents that he or she understands (a) the contents and requirements of the 83(b) Election, (b) the application of Section 83(b) to the receipt of the Shares by the Grantee
pursuant to this Agreement, (c) the nature of the election to be made by the Grantee under Section 83(b) and the consequences of either making or not making the 83(b) Election, and (d) the effect and requirements of the 83(b) Election
under relevant state and local tax laws. The Grantee further represents that he or she intends OR does not intend to file an election pursuant to Section 83(b) with the Internal Revenue Service within thirty (30) days
following the date of this Agreement, and submit a copy of such election with his or her federal tax return for the calendar year in which the date of this Agreement falls.

 [NOTE: The Grantee must cross through the inapplicable language in the last sentence of the preceding
paragraph, and initial here:                      .] 

7.     Additional Securities. Any securities received as the result of ownership of the Restricted Shares (the
“Additional Securities”), including, but not by way of limitation, warrants, options and securities received as a stock dividend or stock split, or as a result of a recapitalization or reorganization or other similar change in the
Company’s capital structure, shall be retained in escrow in the same manner and subject to the same conditions and restrictions as the Restricted Shares with respect to which they were issued, including, without limitation, the Vesting Schedule
set forth in the Notice and the Company’s Repurchase Rights. The Grantee shall be entitled to direct the Company to exercise any warrant, option or other right received as Additional Securities upon supplying the funds necessary to do so, in
which event the securities so purchased shall constitute Additional Securities, but the Grantee may not direct the Company to sell any such warrant, option or right. If Additional Securities consist of a convertible security, the Grantee may
exercise any conversion right, and any securities so acquired shall constitute Additional Securities. Appropriate adjustments to reflect the distribution of Additional Securities shall be made to the price per share to be paid upon the exercise of
the Repurchase Right in order to reflect the effect of any such transaction upon the Company’s capital structure. In the event of any change in certificates evidencing the Shares or the Additional Securities by reason of any recapitalization,
reorganization or other transaction that results in the creation of Additional Securities, the escrow holder is authorized to deliver to the issuer the certificates evidencing the Shares or the Additional Securities in exchange for the certificates
of the replacement securities. 
 8.     Company’s Repurchase Rights. 

(a)     Grant of Repurchase Rights. The Company is hereby granted the right to repurchase all or any portion
of the Shares that are Restricted Shares and any Additional Securities (the “Repurchase Right”) exercisable at any time during the period commencing on the date the Grantee’s Continuous Service terminates for any reason, with
or without cause (including death or disability) (the “Termination Date”) and ending ninety (90) days after the first date on which the Repurchase Right may be exercised without incurring an accounting expense with respect to
such exercise (the “Share Repurchase Period”). Notwithstanding the foregoing, if a Milestone under the Program is unfulfilled as of a particular date and the Shares attributable to such Milestone are not reallocated to another
Milestone, thereby leading to a forfeiture of Shares, such forfeited Shares shall be permanently restricted from vesting with the Grantee, and the Company shall be entitled to repurchase such Shares at that time or any time thereafter,
notwithstanding any contrary provision of this Agreement or the Plan.

(File No. 000-50216) on May 14, 2010 
 ## indicates portions of the exhibit that have been omitted pursuant to a request for
confidential information and filed separately with the Commission. 
  

 (b)     Exercise of the Repurchase Right. The Repurchase
Right shall be exercisable by written notice delivered to the Grantee prior to the expiration of the Share Repurchase Period. The notice shall indicate the number of Shares and any Additional Securities to be repurchased and the date on which the
repurchase is to be effected, such date to be not later than the last day of the Share Repurchase Period. On the date on which the repurchase is to be effected, the Company and/or its assigns shall pay to the Grantee in cash or cash equivalents
(including the cancellation of any purchase-money indebtedness) for Restricted Shares being repurchased, the Purchase Price per Share or Additional Securities previously paid by the Grantee to the Company for such Shares and Additional Securities.
Upon such payment to the Grantee or into escrow for the benefit of the Grantee, the Company and/or its assigns shall become the legal and beneficial owner of the Shares and Additional Securities being repurchased and all rights and interest thereon
or related thereto, and the Company shall have the right to transfer to its own name or its assigns the number of Shares and Additional Securities being repurchased, without further action by the Grantee. 

(c)     Assignment. Whenever the Company shall have the right to purchase Shares and Additional Securities
under this Repurchase Right, the Company may designate and assign one or more employees, officers, directors or shareholders of the Company or other persons or organizations, to exercise all or a part of the Company’s Repurchase Right.

 (d)     Termination of the Repurchase Right. The Repurchase Right shall terminate with respect to
any Shares for which it is not timely exercised. In addition, the Repurchase Right shall terminate, and cease to be exercisable, with respect to all vested Shares upon the date on which such shares cease to be Restricted Shares. 

(e)     Corporate Transaction/Change in Control. Immediately prior to the consummation of a Corporate
Transaction described in Section 2(q)(i), (ii) or (iii) of the Plan or a Change in Control, the Repurchase Right as to all unvested Shares and any Additional Securities shall automatically lapse in its entirety, except to the extent
this Agreement is Assumed, in which case the Repurchase Right shall apply to the new capital stock or other property received in exchange for the unvested Shares and Additional Securities in consummation of the Corporate Transaction or Change in
Control, but only to the extent the unvested Shares and Additional Securities are at the time covered by such right. The Repurchase Right as to Restricted Shares and Additional Securities shall apply to the new capital stock or other property
(including cash paid other than as a regular cash dividend) received in exchange for the Shares and Additional Securities in consummation of a Corporate Transaction and such stock or property shall be deemed Additional Securities for purposes of
this Agreement, but only to the extent the Shares and Additional Securities are at the time covered by such Repurchase Right. Appropriate adjustments shall be made to the price per share payable upon exercise of the Repurchase Right to reflect the
effect of the Corporate Transaction.

 9.     Stop-Transfer Notices. In order to ensure compliance
with the restrictions on transfer set forth in this Agreement, the Notice or the Plan, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company transfers its own securities, it may
make appropriate notations to the same effect in its own records. 
 10.     Refusal to Transfer. The
Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to
vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY

of ownership in, make any short sale of, pledge or otherwise transfer or dispose of any interest in any Common Stock or any securities convertible into or exchangeable or exercisable for or any
other rights to purchase or acquire Common Stock (except Common Stock included in such public offering or acquired on the public market after such offering) during the 180-day period following the effective date of a registration statement of the
Company filed under the Securities Act of 1933, as amended, or such shorter period of time as the Lead Underwriter shall specify. Grantee further agrees to sign such documents as may be requested by the Lead Underwriter to effect the foregoing and
agrees that the Company may impose stop-transfer instructions with respect to such Common Stock subject until the end of such period. The Company and Grantee acknowledge that each Lead Underwriter of a public offering of the Company’s stock,
during the period of such offering and for the 180-day period thereafter, is an intended beneficiary of this Section 12. 

(b)     No Amendment Without Consent of Underwriter. During the period from identification as a Lead
Underwriter in connection with any public offering of the Company’s Common Stock until the earlier of (i) the expiration of the lock-up period specified in Section 12(a) in connection with such offering or (ii) the abandonment of
such offering by the Company and the Lead Underwriter, the provisions of this Section 12 may not be amended or waived except with the consent of the Lead Underwriter. 

13.     Grantee’s Representations. In the event the Shares purchasable pursuant to this Agreement have
not been registered under the Securities Act of 1933, as amended, at the time of purchase, the Grantee shall, if required by the Company, concurrently with the purchase of the Shares, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C. 
 14.     Transferability. No
benefit payable under, or interest in, this Agreement or in the shares of Common Stock that are scheduled to be issued hereunder shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge
and any such attempted action shall be void and no such benefit or interest shall be, in any manner, liable for, or subject to, your or your beneficiary’s debts, contracts, liabilities or torts; provided, however, nothing in this
Section 14 shall prevent transfer (i) by will, (ii) by applicable laws of descent and distribution or (iii) to an Alternate Payee to the extent that a QDRO so provides, as further described in Section 20 of the Plan.

 15.     No Contract for Employment. This Agreement is not an employment or service contract and
nothing in this Agreement shall be deemed to create in any way whatsoever any obligation of the Grantee to continue in the employ or service of the Company, or of the Company to continue to employ Grantee.

all the provisions of the Plan, which provisions are hereby made a part of this Agreement, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan.
In the event of any conflict between the provisions of this Agreement and those of the Plan, the provisions of the Plan shall control. 

17.     No Compensation Deferral. This Award is not intended to constitute “nonqualified deferred
compensation” within the meaning of Code Section 409A, but rather is intended to be exempt from the application of Code Section 409A. To the extent that the Award is nevertheless deemed to be subject to Code Section 409A for any
reason, this Award shall be interpreted in accordance with Code Section 409A and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may
be issued after the Grant Date. Notwithstanding any provision herein to the contrary, in the event that following the Grant Date, the Administrator (as defined in the Plan) determines that the Award may be or become subject to Code
Section 409A, the Administrator may adopt such amendments to the Plan and/or this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the
Administrator determines are necessary or appropriate to (a) exempt the Plan and/or the Award from the application of Code Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to this option, or
(b) comply with the requirements of Code Section 409A. 
 18.     Acknowledgement. By
electing to accept this Agreement, you acknowledge receipt of this Agreement and hereby confirm your understanding that the terms set forth in this Agreement constitute, subject to the terms of the Plan, which terms shall control in the event of any
conflict between the Plan and this Agreement, the entire agreement and understanding of the parties with respect to the matters contained herein and supersede any and all prior agreements, arrangements and understandings, both oral and written,
between the parties concerning the subject matter of this Agreement. The Company may, in its sole discretion, decide to deliver any documents related to Units awarded under the Plan or future Units that may be awarded under the Plan by electronic
means or request your consent to participate in the Plan by electronic means. You hereby consent to receive such documents by electronic delivery and agree to participate in the Plan through an on-line or electronic system established and maintained
by the Company or another third party designated by the Company. 
 19.     Entire Agreement: Governing
Law. The Notice, the Plan and this Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Grantee with
respect to the subject matter hereof, and may not be modified adversely to the Grantee’s interest except by means of a writing signed by the Company and the Grantee. These agreements are to be construed in accordance with and governed by the
internal laws of the State of Colorado, without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the internal laws of the State of Colorado to the rights and duties of the parties.
Should any provision of the Notice or this Agreement be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable.

disputes arising out of or relating to the Notice, the Plan and this Agreement. The Company, the Grantee, and the Grantee’s assignees (the “parties”) shall attempt in good faith to resolve any disputes arising out of or
relating to the Notice, the Plan and this Agreement by negotiation between individuals who have authority to settle the controversy. Negotiations shall be commenced by either party by notice of a written statement of the party’s position and
the name and title of the individual who will represent the party. Within thirty (30) days of the written notification, the parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary,
to resolve the dispute. If the dispute has not been resolved by negotiation, the parties agree that any suit, action, or proceeding arising out of or relating to the Notice, the Plan or this Agreement shall be brought in the Courts of the State of
Colorado, and the parties shall submit to the jurisdiction of such courts. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought
in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of this Section 21 shall for any reason be held invalid or unenforceable, it
is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable. 

22.     Compliance with Laws. Notwithstanding anything contained in this Agreement or the Plan, the Company
may not take any actions hereunder, and no award shall be granted, that would violate the Securities Act of 1933, as amended (the “Act”), the Securities Exchange Act of 1934, as amended, the Code, or any other securities or tax or
other applicable law or regulation. Notwithstanding anything to the contrary contained herein, the shares issuable upon vesting shall not be issued unless such shares are then registered under the Act, or, if such shares are not then so registered,
the Company has determined that such vesting and issuance would be exempt from the registration requirements of the Act. 

23.     Notices. Any notice required or permitted hereunder shall be given in writing and shall be deemed
effectively given upon personal delivery or upon deposit in the United States mail by certified mail (if the parties are within the United States) or upon deposit for delivery by an internationally recognized express mail courier service (for
international delivery of notice), with postage and fees prepaid, addressed to the other party at its address as shown beneath its signature in the Notice, or to such other address as such party may designate in writing from time to time to the
other party.

 In connection with
the purchase of the above-listed Securities, the undersigned Grantee represents to the Company the following: 
 (a)
    Grantee is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. Grantee is
acquiring these Securities for investment for Grantee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act of 1933, as amended (the
“Securities Act”). 
 (b)     Grantee acknowledges and understands that the Securities
constitute “restricted securities” under the Securities Act and have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon among other things, the bona fide nature of
Grantee’s investment intent as expressed herein. In this connection, Grantee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Grantee’s representation was
predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period
of one year or any other fixed period in the future. Grantee further understands that the Securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available.
Grantee further acknowledges and understands that the Company is under no obligation to register the Securities. Grantee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in the opinion of counsel satisfactory to the Company.

 (c)     Grantee is familiar with the provisions of Rule 144
promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain
conditions. The Securities may be resold in certain limited circumstances subject to the provisions of Rule 144, which requires (i) the resale to occur not less than six months after the later of the date the Securities were sold by the Company
or the date the Securities were sold by an affiliate of the Company, within the meaning of Rule 144; (ii) in the case of acquisition of the Securities by a non-affiliate who subsequently holds the Securities less than one year, the availability
of certain public information about the Company; and (iii) in the case of acquisition of the Securities by an affiliate: (A) the resale being made through a broker in an unsolicited “broker’s transaction” or in transactions
directly with a market maker (as said term is defined under the Securities Exchange Act of 1934), (B) the availability of certain public information about the Company, (C) the amount of Securities being sold during any three month period
not exceeding the limitations specified in Rule 144(e), and (D) the timely filing of a Form 144, if applicable. Other restrictions may also apply to sales of the Securities, and Grantee understands that the Securities may not be readily resold,
and that delays may occur in selling the Securities, even if they are eligible for sale under Rule 144. 
 (d)
    Grantee further understands that in the event all of the applicable requirements of Rule 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered
offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk. Grantee understands that no assurances can be given that any such other registration exemption will be available in such event, and that the Securities may not be salable by Grantee. 

(e)     Grantee represents that he is a resident of the State of
                                .

 Exhibit 10.1 

EXECUTIVE AGREEMENT 

This Executive Agreement dated as of May 7, 2010 is by and between Parametric Technology Corporation, a Massachusetts corporation
(the “Company”), and C. Richard Harrison (the “Executive”). 
  

	1.	Definitions. 

 For the
purposes of this Agreement: 
 (a) “Cause” means: 

(i) the Executive’s willful and continued failure to substantially perform his duties to the Company (other than any such failure
resulting from the Employee’s incapacity due to physical or mental illness), provided that the Company has delivered a written demand for performance to the Executive specifically identifying the manner in which the Company believes that the
Executive has not substantially performed his duties and the Executive does not cure such failure within thirty (30) days after such demand; 

(ii) willful conduct by the Executive which is demonstrably and materially injurious to the Company; 

(iii) the Executive’s conviction of, or pleading of guilty or nolo contendere to, a felony; 

(iv) the Executive’s entry in his personal capacity into a consent decree relating to the business of the Company with any
government body; or 
 (v) the Executive’s willful material violation of any material provision of his Non-Disclosure,
Non-Competition and Invention Agreement with the Company; provided that, if such violation is able to be cured, the Executive has not, within thirty (30) days after written demand by the Company, cured such violation. 

For purposes of this definition, no act or failure to act on the Executive’s part shall be deemed “willful” unless done or omitted to be
done by the Executive not in good faith and without reasonable belief that his action or omission was in the best interests of the Company. 

(b) “Change in Control” means the occurrence of any of the following events: 

(i) any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”) (other than the Company, any trustee or other fiduciary holding securities under an employee benefit plan of the Company, or any corporation owned directly or indirectly by the stockholders of the Company in substantially
the same proportion as their ownership of stock in the Company) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing fifty percent
(50%) or more of the combined voting power of the Company’s then outstanding securities (other than as a result of acquisitions of such securities from the Company); 

(ii) individuals who, as of the date hereof, constitute the board of directors of the Company (the “Incumbent Board”) cease for
any reason to constitute at least a majority of the board of directors, provided that any person becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s stockholders, was approved by a vote
of at least a majority of the directors then comprising the Incumbent Board (other than an election or nomination of an individual whose initial assumption of office is in connection with an actual or threatened election contest relating to the
election of the directors of the Company) shall be, for purposes of this Agreement, considered to be a member of the Incumbent Board; 

(iii) the consummation of a merger, share exchange or consolidation of the Company or any subsidiary of the Company with any other entity
(each a “Business Combination”), other than (x) a Business Combination that would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by
being converted into voting securities of another 

 
entity) beneficial ownership, directly or indirectly, of a majority of the combined voting power of the Company or the surviving entity (including any person that, as a result of such
transaction, owns all or substantially all of the Company’s assets either directly or through one or more subsidiaries) outstanding immediately after such Business Combination or (y) a merger, share exchange or consolidation effected to
implement a recapitalization of the Company (or similar transaction) in which no “person” (as defined above) is or becomes the beneficial owner of fifty percent (50%) or more of the combined voting power of the Company’s then
outstanding securities; or 
 (iv) the stockholders of the Company approve (x) a plan of complete liquidation of the
Company; or (y) an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets but excluding a sale or spin-off of a product line, business unit or line of business of the Company if the
remaining business is significant as determined by the Company’s board of directors in its sole discretion. 
 (c)
“Code” means the U.S. Internal Revenue Code of 1986, as amended. 
 (d) “Disability” means such
physical or mental incapacity as to make the Executive unable to perform the essential functions of his employment duties for a period of at least sixty (60) consecutive days with or without reasonable accommodation. If any question shall arise
as to whether during any period the Executive is so disabled as to be unable to perform the essential functions of his employment duties with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to
the Company a certification in reasonable detail by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is
expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question
shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive. 

(e) “Good Reason” means the occurrence, without the Executive’s consent and without Cause, of any of the following
events (provided that the Executive shall have given the Company written notice describing such event within ninety (90) days of its initial existence and the matter shall not have been fully remedied by the Company within thirty (30) days
after receipt of such notice): 
 (i) the Executive’s ceasing to be a member of the Company’s board of directors by
reason of the failure of the Company to re-nominate the Executive for election or failure of the Executive to be elected by the stockholders of the Company; 

(ii) any breach by the Company of its material obligations under this Agreement; or 

(iii) any requirement that the Executive relocate to a primary work site that would increase the Executive’s one-way commute
distance by more than fifty (50) miles from the Executive’s then principal residence. 
  

	2.	Services to be Performed by the Executive. 

(a) Position and Services. Effective October 1, 2010 (the “Commencement Date”), the Executive shall cease serving as
Chief Executive Officer of the Company and shall become the Company’s Executive Chairman, an executive officer of the Company. As of the Commencement Date, the Executive will perform certain employment duties, reporting to the President and
Chief Executive Officer. The Executive’s employment duties will include enhancing relationships with the Company’s key customers, partners and investors and other activities focused on improving the business climate for the Company around
the world, and such other duties consistent with his position as may be reasonably assigned to him by the Company’s Chief Executive Officer (“Employment Duties”). 

(b) Obligations. During the Term (as defined in Section 2(c)), the Executive will be available on a part-time time basis for
consultation and the performance of the Employment Duties as requested by the Chief Executive Officer. The Executive will use good faith efforts to discharge his obligations under this Agreement to the best of his ability and in accordance with the
Company’s Code of Business Conduct and Ethics. During the 
  

 2 

 
Term, the Executive agrees not to actively engage in any other employment, occupation, or consulting activity for any direct or indirect remuneration without the prior approval of the
Company’s Chief Executive Officer (which approval will not be unreasonably withheld); provided, however, that the Executive may, without the approval of the Chief Executive Officer, serve in any capacity with any civic, educational, or
charitable organization, provided such services do not interfere with the Executive’s obligations to the Company. 
 (c)
Term. The Executive’s employment shall continue in effect until 11:59 p.m. on November 30, 2012 unless earlier terminated in accordance with Section 4 hereof (the period from the Commencement Date until the earlier of such date
and the date of termination of the Executive’s employment being the “Term”). Except as otherwise expressly set forth in this Agreement, upon the termination of the Executive’s employment, the respective rights and obligations of
the parties hereunder shall survive to the extent necessary to carry out the intentions of the parties as embodied herein. 
  

	3.	Compensation & Benefits. 

(a) Salary. During the Term, for the period from October 1, 2010 through September 30, 2011, the Company will pay the
Executive an annual salary of $500,000 and for the period from October 1, 2011 through November 30, 2012, the Company will pay the executive an aggregate salary of $500,000, such salary to be paid periodically in accordance with the
Company’s normal payroll practices. 
 (b) Benefits. As a part time employee, during the Term, the Executive shall
be entitled to participate on the same terms as employees generally in the Company’s employee benefit plans, such as the Company’s 401(k) plan and PTO policy, to the extent he is eligible under the applicable plans. In lieu of other
benefits for which the Executive ceases to be eligible upon commencing part-time employment status, which may include but not be limited to health, dental, vision, life and long term disability insurance, the Executive will be paid a one time, lump
sum payment of $110,000 within 30 days following the Commencement Date. If permitted by the terms of the respective plan or by law, the Executive shall have the option to continue discontinued benefits, at his expense, under COBRA or the applicable
policy conversion options. 
 (c) Equity. Effective as of October 1, 2010, the Executive will be granted restricted
stock units with a value equal to approximately $3,000,000. The actual number of restricted stock units to be granted shall be based on the closing price of the Company’s common stock on October 1, 2010. The restricted stock units will be
granted under the Company’s 2000 Equity Incentive Plan and shall vest in two substantially equal installments on each of September 30, 2011 and September 30, 2012 if this Agreement is then in effect. 

 

	4.	Termination. 

 If, before
the Commencement Date, the Executive’s employment with the Company is terminated for any reason, or a Change In Control occurs, this Agreement shall thereupon automatically terminate. During the Term, the Executive’s employment may be
terminated by the Executive or the Company as follows and with the respective effects set forth in Section 5. 
 (a) By
the Executive. During the Term, the Executive’s employment may be terminated by the Executive at any time upon not less than thirty (30) days’ written notice to the Company for convenience or for Good Reason. 

(b) By the Company. During the Term, the Executive’s employment may be terminated at any time by the Company for convenience,
for Cause or because of the Executive’s Disability. 
 (c) Upon a Change in Control. During the Term, the
Executive’s employment will automatically terminate upon a Change in Control. 
  

 3 

	5.	Effect of Certain Termination Events. 

The provisions of this Section 5 shall apply to termination of the Executive’s employment during the Term in the respective
circumstances set forth below. 
 (a) By the Executive for Convenience or by the Company for Nonperformance. If the
Executive terminates his employment for convenience or if the Company terminates the Executive’s employment for Cause solely pursuant to Section 1(a)(i): 

(i) to the extent not then vested, the restricted stock units granted pursuant to Section 3(c) and any other shares of restricted
stock, restricted stock units, stock options, stock appreciation rights or other equity awards granted to the Executive by the Company during the Term, including any extension thereof, shall thereupon be terminated and forfeited without
compensation; 
 (ii) if and for so long as the Executive remains a member of the Company’s board of directors, all shares
of restricted stock, restricted stock units, stock options, stock appreciation rights and other equity awards granted to the Executive by the Company before the Commencement Date shall continue to vest as though the Executive remained employed by
the Company; 
 (iii) if the Executive remains a member of the Company’s board of directors, the period during which the
Executive may exercise any stock options then currently vested shall be extended until the earliest of (x) the expiration of the term of the applicable option, (y) the expiration of the post-termination exercise period for the applicable
option (for which purpose, termination of board service shall be substituted for termination of employment) and (z) February 28, 2013; 

(iv) upon the later of the termination of the Executive’s employment and the termination of his membership on the Company’s
board of directors, all remaining unvested shares of restricted stock, restricted stock units, stock options, stock appreciation rights and other equity awards granted to the Executive by the Company shall be terminated and forfeited without
compensation; and 
 (v) no further salary or other amounts, other than accrued and unpaid amounts, shall be payable to the
Executive. 
 (b) By the Company for Cause. If the Company terminates the Executive’s employment for Cause, other
than solely pursuant to Section 1(a)(i): 
 (i) all unvested shares of restricted stock, restricted stock units, stock
options, stock appreciation rights and other equity awards granted to the Executive by the Company shall thereupon be terminated and forfeited without compensation as of the termination date and 

(ii) no further salary or other amounts, other than accrued and unpaid amounts, shall be payable to the Executive. 

(c) Death or Disability. Effective upon termination of the Executive’s employment due to his death or by the Company due to
his Disability: 
 (i) all restrictions applicable to restricted stock issued by the Company and held by the Executive shall
immediately lapse and 
 (ii) all outstanding stock options, stock appreciation rights, restricted stock units and other equity
awards issued by the Company shall immediately become vested and exercisable in full. 
  

 4 

 (d) Other Terminations. If during the Term the Executive’s employment is
terminated (x) by the Executive for Good Reason, (y) by the Company for convenience or (z) upon a Change in Control, the following shall occur, effective upon such termination: 

(i) Effect on Outstanding Equity. With respect to all equity awards issued by the Company and held by the Executive, whether
issued during the Term or prior thereto: 
 (A) all restrictions applicable to restricted stock issued by the Company and held
by the Executive, other than any restriction the lapse of which is based upon achievement of performance goals, shall immediately lapse; 

(B) all vesting conditions applicable to all stock options, stock appreciation rights, restricted stock units, and other equity awards
granted to the Executive by the Company, other than any vesting conditions based upon achievement of performance goals, shall thereupon be deemed satisfied and, except to the extent of any such performance-based conditions, such awards shall become
exercisable or distributable in full; and 
 (C) each outstanding stock option granted to the Executive by the Company shall,
to the extent vested after giving effect to clause (B), remain exercisable following the termination of the Executive’s employment until the close of business on the earlier of (1) the end of the original maximum term of such option and
(2) November 30, 2012. 
 (ii) Payment of Contract Amounts. The Executive shall be entitled to a lump sum
payment in an amount equal to the amounts payable under Sections 3(a) and 3(b) less all amounts paid pursuant to those subsections during the Term to the date of such termination, payable within forty-five (45) days after the termination
date. 
  

	6.	Taxes. 

 (a)
Withholding. All payments to be made to the Executive under this Agreement will be subject to any required withholding of federal, state and local income and employment taxes. In addition, the Company may withhold from any payments hereunder
any amounts attributable to withholding taxes applicable to the vesting of or lapse of restrictions on any restricted stock or restricted stock units held by the Executive or the exercise of any nonqualified stock options held by the Executive,
including, in its discretion withholding from any shares deliverable to the Executive such number of shares as the Company determines is necessary to satisfy such tax obligations, valued at their fair market value (determined pursuant to the
respective Company equity compensation plan) as of the date of such vesting or lapse of restrictions. 
 (b) Limitations on
Payments. 
 (i) If it is determined that any payment, benefit or distribution provided for in this Agreement or otherwise
(each, a “Payment” and collectively, the “Payments”) from the Company to or for the benefit of the Executive to which the Executive first becomes entitled as a result of an event occurring on or after October 1, 2010
(x) constitutes a “parachute payment” within the meaning of Section 280G of the Code and (y) but for this subsection (b), would be subject to excise tax imposed by Section 4999 of the Code (the “Excise Tax”),
such Payments shall be either 
 (A) delivered in full, or 

(B) delivered to such lesser extent that would result in no portion of the Payments being subject to the Excise Tax, 

whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the Excise Tax, results in the receipt
by the Executive on an after tax basis, of the greatest amount of Payments, notwithstanding that all or some portion of the Payments may be taxable under Section 4999 of the Code. Unless the Company and Executive otherwise agree in writing, any
determination required under this Section 6(b)(i) shall be made in writing in good faith by an independent accounting firm selected by the Company, whose determinations shall be binding upon the Company and the Executive (the
“Accountants”), in good faith consultation with the Executive. 
  

 5 

 (ii) In the event a reduction in the Payments is required hereunder, the Company shall
promptly give the Executive notice to that effect and the Executive may then determine, in his sole discretion, which and how much of the Payments shall be eliminated or reduced (as long as, after such election, none of the Payments are subject to
the Excise Tax), and shall advise the Company in writing of his election within ten (10) days of his receipt of the Company’s notice. If no such election is made by the Executive within such period, the Company may determine which and how
much of the Payments shall be eliminated or reduced (as long as, after such determination, none of the Payments are subject to the Excise Tax) and shall notify the Executive promptly of such determination. 

(iii) For purposes of making the calculations required by this Section 6(b), the Accountants may make reasonable assumptions and
approximations concerning the application taxes and may rely on reasonable good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Executive shall furnish to the Accountants such information
and documents as the Accountants may reasonable request in order to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this
Section 6(b). 
 (iv) If the Payments are reduced to avoid the Excise Tax pursuant to Section 6(b)(i) hereof and
notwithstanding such reduction, the IRS determines that the Executive is liable for the Excise Tax as a result of the receipt of Payments from the Company, then the Executive shall be obligated to pay to the Company (the “Repayment
Obligation”) an amount of money equal to the “Repayment Amount.” The Repayment Amount shall be the smallest such amount, if any, as shall be required to be paid to the Company so that the Executive’s net proceeds with respect to
the Payments (after taking into account the payment of the Excise Tax imposed on such benefits) shall be maximized. Notwithstanding the foregoing, the Repayment Amount shall be zero if a Repayment Amount of more than zero would not eliminate the
Excise Tax in accordance with the principles of Section 6(b)(i). If the Excise Tax is not eliminated through the performance of the Repayment Obligation, the Executive shall pay the Excise Tax. The Repayment Obligation shall be discharged
within 30 days of either (A) the Executive’s entering into a binding agreement with the IRS as to the amount of Excise Tax liability, or (B) a final determination by the IRS or a court decision requiring the Executive to pay the
Excise Tax from which no appeal is available or is timely taken. 
  

	7.	Certain Payments to Specified Employees. 

Notwithstanding anything to the contrary in this Agreement, if the Executive is a “specified employee” within the meaning of
Code Section 409A(a)(2)(B)(i) at the time of the Executive’s separation from service with the Company, no payment or benefit payable or provided to the Executive pursuant to this Agreement that constitutes an item of deferred compensation
under Code Section 409A and becomes payable by reason of the Executive’s termination of employment with the Company will be paid or provided to the Executive prior to the earlier of (i) the expiration of the six (6) month period
following the date of the Executive’s “separation from service” (as such term is defined by Code Section 409A and the regulations promulgated thereunder), or (ii) the date of the Executive’s death, but only to the
extent such delayed commencement is otherwise required in order to avoid a prohibited distribution under Code Section 409A(a)(2). The payments and benefits to which the Executive would otherwise be entitled during the first six (6) months
following his separation from service shall be accumulated and paid or provided, as applicable, in a lump sum, on the date that is six (6) months and one day following the Executive’s separation from service (or if such date does not fall
on a business day of the Company, the next following business day) and any remaining payments or benefits will be paid in accordance with the normal payment dates specified for them herein. 

 

	8.	Successors and Assigns. 

(a) This Agreement is personal to the Executive and is not assignable by the Executive, other than by will or the laws of descent and
distribution, without the prior written consent of the Company. 
 (b) This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and acquirers and assigns. 
  

 6 

	9.	Conditions to Payment of Severance. 

Notwithstanding any other provision of this Agreement, the Executive’s entitlement to receive any of the payments and other benefits
contemplated by Section 5 hereof shall be contingent upon: 
 (a) execution by the Executive prior to
the forty-fifth
(45th
) day following the termination of his employment of a release in substantially the form of Appendix A
hereto (the “Release”), which has not subsequently been revoked, and the Executive hereby acknowledges and agrees that the Company’s entering into this Agreement and agreement to make such payments are and shall be good and sufficient
consideration for such Release; and 
 (b) the Executive’s continued compliance with the material terms of this Agreement,
as applicable, and those of his Non-Disclosure, Non-Competition and Invention Agreement with the Company. 
  

	10.	Miscellaneous. 

 (a)
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, except any such laws that would render such choice of law ineffective. 

(b) Compliance with Section 409A. This Agreement is intended, to the extent applicable, to constitute good faith compliance
with the requirements of Section 409A of the Code. The Company and the Executive agree that they shall cooperate in good faith to amend any provision hereof to the extent required to maintain compliance with the provisions of Section 409A
of the Code as they may be modified hereafter (including by subsequent regulations or other guidance of the Internal Revenue Service). 

(c) Amendment. This Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto
or their respective successors and legal representatives. 
 (d) Effect on Earlier Agreements. This Agreement constitutes
the entire understanding and agreement between the parties hereto with regard to the compensation payable to the Executive in the circumstances described herein, superseding all prior understandings and agreements, whether oral or written relating
to the subject matter of this Agreement. If a Change In Control or termination of the Executive’s employment occurs prior to the Commencement Date, any obligations of the Company to the Executive shall be as set forth in the Amended and
Restated Executive Agreement dated as of June 26, 2008 by and between the Company and the Executive (the “Prior Agreement”). As of the Commencement Date, this Agreement shall supersede the Prior Agreement, which shall thereupon be
terminated and of no further force and effect. For the purposes of clarity, with respect to a Change In Control or termination of the Executive’s employment on or after the date hereof and before the Commencement Date, payments and benefits
under the Prior Agreement shall be exclusive and no payments or benefits shall be provided under this Agreement, and with respect to a Change in Control or termination of the Executive’s Employment occurring on or after the Commencement Date,
payments and benefits shall be available only under this Agreement. The agreements evidencing any equity awards granted by the Company to the Executive are hereby and will be deemed amended to give effect to the provisions of Section 5 of this
Agreement. 
 The Executive acknowledges and agrees that the change in his position from Chief Executive Officer to Executive
Chairman, the related changes in compensation provided for in this Agreement and the naming of another person as Chief Executive Officer of the Company effective as of October 1, 2010 shall not constitute “Good Reason” or other
grounds for resignation by the Executive under the Prior Agreement and that the Executive shall have no right to receive compensation or any other benefits under the Prior Agreement by reason of such events. 

(e) Partial Invalidity. If any provision in this Agreement is held by a court of competent jurisdiction to be invalid, void, or
unenforceable, the remaining provisions will nevertheless continue in full force without being impaired or invalidated in any way. 

(f) Expenses. The Company agrees to pay as incurred and within 20 days after submission of supporting documentation, to the full
extent permitted by law, all legal fees and expenses the Executive may reasonably incur as a result of any contest by the Company, the Executive or others of the validity or enforceability 

 

 7 

 
of, or liability under, any provision of this Agreement (including as a result of any contest by the Executive about the amount of any payment pursuant to this Agreement) with respect to which
the Executive is successful on the merits, plus, in each case, interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code. The Company’s payment of any eligible expenses must be made no
later than December 31 of the year after the year in which the expense was incurred. 
 (g) Notices. All notices and
other communications hereunder shall be in writing and shall be delivered by hand delivery, by a reputable overnight courier service, or by registered or certified mail, return receipt requested, postage prepaid. Notice to the Executive shall be
addressed to him at the last address contained in the Company’s records and notice to the Company shall be addressed to: 

Parametric Technology Corporation 

140 Kendrick Street 

Needham, MA 02494 

Attention: General Counsel 

Notice shall be provided to such other address as either party shall have furnished to the other in writing in accordance herewith. Any notice or
communication shall be deemed to be delivered upon the date of hand delivery, one day following delivery to an overnight courier service, or three days following mailing by registered or certified mail. 

EXECUTED as of the date first written above.
