Exhibit 10.26

AUTODESK, INC.

AMENDED AND RESTATED

CARL BASS EMPLOYMENT AGREEMENT

This Amended and Restated Employment Agreement (the “Agreement”) is entered into as of December 12, 2008, by and between Autodesk, Inc. (the “Company”) and Carl Bass (“Executive”).

1. Duties and Scope of Employment.

(a) Positions and Duties. This Agreement was originally effective May 1, 2006 (the “Effective Date”). Pursuant to this Agreement as amended and restated, Executive will continue to serve as the Company’s President and Chief Executive Officer. Executive will report to the Company’s Board of Directors (the “Board”). Executive will continue to render such business and professional services in the performance of his duties, consistent with Executive’s position in the Company, as are reasonably assigned to him by the Board. The period Executive is employed by the Company under this Agreement is referred to herein as the “Employment Term.”

(b) Board Membership. Executive has served as a member of the Board since the Effective Date. At each annual meeting of the Company’s stockholders during the Employment Term, the Company will nominate Executive to serve as a member of the Board. Executive’s service as a member of the Board will be subject to any required stockholder approval. Upon the termination of Executive’s employment for any reason, unless otherwise requested by the Board, Executive will be deemed to have resigned from the Board (and all other positions held at the Company and its affiliates) voluntarily and without further action from the Board, effective as of the end of Executive’s employment, and Executive, at the Board’s request, will execute any documents necessary to reflect his resignation.

(c) Obligations. During the Employment Term, Executive will devote his full business time and efforts to the Company and he will use good faith efforts to discharge Executive’s obligations under this Agreement to the best of Executive’s ability and in accordance with each of the Company’s ethics guidelines, conflict of interest policies and Code of Business Conduct. For the duration of the Employment Term, 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 Board (which approval will not be unreasonably withheld); provided, however, that Executive may, without the approval of the Board, serve in any capacity with any civic, educational, or charitable organization, provided such services do not interfere with Executive’s obligations to Company. Executive may also serve, without the prior approval of the Board, as a member of the board of directors of two publicly traded companies (other than the Company) and such service will not constitute a violation of this Section 1(c).

2. At-Will Employment. Executive and the Company agree that Executive’s employment with the Company constitutes “at-will” employment. Executive and the Company acknowledge that this employment relationship may be terminated at any time, upon thirty (30) days written notice to the other party, with or without good cause or for any or no cause, at the option either of the Company or Executive. However, as described in this Agreement, Executive may be entitled to severance and other benefits depending upon the circumstances of Executive’s termination of employment.

3. Compensation.

(a) Base Salary. Effective as of April 1, 2008, the Company will pay Executive an annual salary of $900,000 as compensation for his services (such annual salary, as is then effective, to be referred to herein as “Base Salary”). The Base Salary will be paid periodically in accordance with the Company’s normal payroll practices and be subject to the usual, required withholdings.

(b) Annual Incentive. Executive will be eligible to receive annual cash incentive compensation payable for the achievement of performance goals established by the Board or by the Compensation Committee of the Board (the “Committee”) under the Company’s Executive Incentive Plan (“EIP”). During the Employment Term, Executive’s target annual incentive (“Target Annual Incentive”) under the EIP will be not less than 100% of Base Salary and shall otherwise be subject to the terms of the EIP. The actual earned annual cash incentive, if any, payable to Executive for any performance period will depend upon the extent to which the applicable performance goals specified by the Committee are achieved or exceeded as set forth in the EIP. For the last three quarters of fiscal year 2007, Executive’s Target Annual Incentive was set at 100% of Base Salary. Any incentive earned during the last three quarters of fiscal year 2007 was pro-rated such that Executive’s Target Incentive was 100% of Base Salary for 75% of that amount, if any, under the EIP.

(c) Stock Options. During the Employment Term, Executive will continue to be eligible to receive grants of options or other equity awards customarily granted to executive officers, at the sole discretion of the Board or the Committee.

4. Employee Benefits. During the Employment Term, Executive will be eligible to participate in accordance with the terms of all Company employee health and dental insurance and other benefit plans, policies, and arrangements that are applicable to other senior executives of the Company, as such plans, policies, and arrangements may exist from time to time. Executive will be entitled to four (4) weeks of paid annual vacation.

5. Expenses. During the Employment Term, the Company will reimburse Executive for reasonable travel, entertainment, and other expenses incurred by Executive in the furtherance of the performance of Executive’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time. The reimbursement of any such eligible expense shall be made on or before the last day of the calendar year following the calendar year in which the expense was incurred

-2-

6. Termination of Employment. In the event Executive’s employment with the Company terminates for any reason, Executive will be entitled to any (a) unpaid Base Salary accrued up to the effective date of termination; (b) unpaid, but earned and accrued annual incentive compensation for any completed fiscal year as of his termination of employment; (c) pay for accrued but unused vacation; (d) benefits or compensation as provided under the terms of any employee benefit and compensation agreements or plans applicable to Executive; (e) unreimbursed business expenses required to be reimbursed to Executive, and (f) rights to indemnification Executive may have under the Company’s Certificate of Incorporation, Bylaws, or separate indemnification agreement, as applicable (“Indemnification Rights”). In addition, if the termination is by the Company without Cause or Executive resigns for Good Reason, Executive will be entitled to the amounts and benefits specified in Section 7.

7. Severance.

(a) Termination Without Cause or Resignation for Good Reason other than in Connection with a Change of Control. If Executive’s employment is terminated by the Company without Cause or if Executive resigns for Good Reason, and such termination is not in Connection with a Change of Control, then, provided that the termination of Executive’s employment constitutes a “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h) (a “Separation from Service”) and subject to Section 8, Executive will receive: (i) payment of an amount equal to two hundred percent (200%) of Executive’s Base Salary (less applicable tax withholdings) for twelve (12) months, such amount to be paid out in substantially equal installments in accordance with the Company’s normal payroll policies; (ii) twelve (12) months accelerated vesting with respect to Executive’s then outstanding, unvested equity awards (other than any awards that vest based on performance), (iii) a period of not less than six (6) months to exercise any vested stock options that were granted to Executive by the Company on or after the date of this Agreement (provided that such options shall expire, if earlier, on the date when they would have expired if Executive’s employment had not terminated) and (iv) if Executive validly elects to continue coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA), reimbursement for premiums paid for continued health benefits for Executive (and any eligible dependents) under the Company’s health plans, payable when such premiums are due until the earlier of (A) twelve (12) months or (B) the date upon which Executive and Executive’s eligible dependents become covered under similar plans. Subject to Section 9, the severance payments under this Subsection (a) shall commence on the sixtieth (60th) day after Executive’s Separation from Service.

(b) Termination Without Cause or Resignation for Good Reason in Connection with a Change of Control. If Executive’s employment is terminated by the Company without Cause or by Executive for Good Reason, and the termination is in Connection with a Change of Control, then, provided that the termination of Executive’s employment constitutes a Separation from Service and subject to Section 8, Executive will receive: (i) a lump sum payment in an amount equal to 200% of the Executive’s annual Base Salary (less applicable tax withholdings); (ii) each of Executive’s then outstanding unvested stock options and any other equity awards (other than any awards that vest based on performance), shall partially accelerate and become vested and exercisable for a number of shares that would have otherwise vested

-3-

within the twenty-four (24) months following such termination of employment; (iii) a period of not less than six (6) months to exercise any vested stock options that were granted to Executive by the Company on or after the date of this Agreement (provided that such options shall expire, if earlier, on the date when they would have expired if Executive’s employment had not terminated); and (iv) if Executive validly elects to continue coverage under COBRA, reimbursement for premiums paid for continued health benefits for the Executive (and any eligible dependents) under the Company’s health plans, payable when such premiums are due until the earlier of (A) twelve (12) months or (B) the date upon which Executive and Executive’s eligible dependents become covered under similar plans. Subject to Section 9, the severance payment under this Subsection (b) shall be made on the later of the sixtieth (60th) day after Executive’s Separation from Service or the consummation of the Change of Control.

(c) Voluntary Termination Without Good Reason or Termination for Cause. If Executive’s employment is terminated voluntarily, including due to death or Disability, without Good Reason or is terminated for Cause by the Company, then, except as provided in Section 6, (i) all further vesting of Executive’s outstanding equity awards will terminate immediately; (ii) all payments of compensation by the Company to Executive hereunder will terminate immediately, and (iii) Executive will be eligible for severance benefits only in accordance with the Company’s then established plans.

(d) Termination due to Death or Disability. If Executive’s employment terminates by reason of death or Disability, then Executive will be entitled to receive benefits only in accordance with the Company’s then applicable plans, policies, and arrangements.

(e) Sole Right to Severance. This Agreement is intended to represent Executive’s sole entitlement to severance payments and benefits in connection with the termination of his employment, except as may be provided in the Company’s Executive Change in Control Program as amended and restated March 31, 2006 (the “Program”). To the extent Executive receives severance or similar payments and/or benefits under any other Company plan, program, agreement, policy, practice, or the like, severance payments and benefits due to Executive under this Agreement will be correspondingly reduced (and vice-versa), and to the extent of any conflict between the terms of this Agreement and the terms of the Program, the terms of this Agreement shall prevail.

8. Conditions to Receipt of Severance; No Duty to Mitigate.

(a) Separation Agreement and Release of Claims. The receipt of any severance pursuant to Section 7 will be subject to Executive signing, not revoking and returning to the Company within fifty (50) days of his Separation from Service a separation agreement and release of claims in the form attached hereto as Exhibit A. No severance or other benefits hereunder will be paid or provided until the separation agreement and release agreement becomes effective. Executive shall not be required to release the Indemnification Rights.

-4-

(b) Non-solicitation and Non-competition. The receipt of any severance or other benefits pursuant to Section 7(a) will be subject to Executive agreeing that during the Employment Term and Continuance Period, Executive will not (i) solicit any employee of the Company (other than Executive’s personal assistant) for employment other than at the Company, or (ii) directly or indirectly engage in, have any ownership interest in or participate in any entity that as of the date of termination, competes with the Company in any substantial business of the Company or any business reasonably expected to become a substantial business of the Company. Executive’s passive ownership of not more than 1% of any publicly traded company and/or 5% ownership of any privately held company will not constitute a breach of this Section 8(b).

(c) Nondisparagement. During the Continuance Period, Executive will not knowingly and materially disparage, criticize, or otherwise make any derogatory statements regarding the Company, and the Company, in its official statements, will not and will instruct the members of the Board and executive officers not to, knowingly and materially disparage, criticize, or otherwise make derogatory statements regarding Executive. Notwithstanding the foregoing, nothing contained in this agreement will be deemed to restrict Executive, the Company or any of the Company’s current or former officers and/or directors from providing information to any governmental or regulatory agency (or in any way limit the content of any such information) to the extent they are requested or required to provide such information pursuant to applicable law or regulation.

(d) Other Requirements. Executive’s receipt of continued severance payments will be subject to Executive continuing to comply with the terms of the Confidential Information Agreement and the provisions of this Section 8.

(e) No Duty to Mitigate. Executive will not be required to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

9. Section 409A

Notwithstanding any of the foregoing, if the Executive is deemed by the Company at the time of his Separation from Service by the Company to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the of the Internal Revenue Code of 1986, as amended (the “Code”), to the extent delayed commencement of any portion of the benefits to which he is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of his benefits shall not be provided to him prior to the earlier of (a) the expiration of the six-month period measured from the date of his Separation from Service with the Company or (b) the date of his death. Upon the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all deferred payments shall be paid to Executive in a lump sum, and any remaining payments due under the Agreement shall be paid as otherwise provided herein. Notwithstanding the foregoing or any other provisions of this Agreement, the Company and Executive agree that, for purposes of the limitations on nonqualified deferred compensation under Code Section 409A, each payment of compensation under this Agreement shall be treated as a separate payment of compensation for purposes of applying the Section 409A deferral election rules and the exclusion from Code Section 409A for certain short-term deferral amounts.

10. Definitions.

(a) Cause. For purposes of this Agreement, “Cause” means: (i) Executive’s engagement in acts of embezzlement, dishonesty or moral turpitude; (ii) the conviction of Executive for having committed a felony; (iii) a breach by Executive of Executive’s fiduciary duties and responsibilities to the Company that result in a material adverse effect on the Company’s business, operations, prospects or reputation; or (iv) gross negligence or bad faith as reasonably determined by the Board; provided that if any of the foregoing events is capable of being cured, the Company will provide written notice of Executive describing the nature of such event and Executive will thereafter have 30 days to cure such event. The foregoing shall not be deemed an exclusive list of the acts or omissions that the Company may consider as grounds for the termination of Executive’s employment, but it is an exclusive list of the acts or omissions that shall be considered “Cause” for the termination of Executive’s employment by the Company.

(b) Change of Control. For purposes of this Agreement, “Change of Control” means (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934) becomes the “beneficial owner” (as defined in Rule 13d-3 of the Securities Exchange Act of 1934), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the Company’s then outstanding voting securities; or (ii) the consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets; or (iii) the consummation of a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which 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 the surviving entity or its parent) at least sixty percent (60%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or (iv) a change in the composition of the Board, as a result of which less than a majority of the Directors are Incumbent Directors. “Incumbent Directors” shall mean Directors who either (A) are Directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the Board with the affirmative votes of at least a majority of those Directors whose election or nomination was not in connection with any transaction described in subsections (i), (ii) or (iii) or in connection with an actual or threatened proxy contest relating to the election of directors of the Company; provided that such Change of Control constitutes a change in ownership or effective control of the Company within the meaning of Code Section 409A and the Treasury Regulations promulgated thereunder.

(c) Disability. For purposes of this Agreement, Disability shall have the same defined meaning as in the Company’s long-term disability plan.

(d) Good Reason. For purposes of this Agreement, “Good Reason” means without the Executive’s written consent, (i) a material reduction in the Executive’s authority or responsibilities (including reporting responsibilities) which shall include, after a Change of Control, the failure to appoint Executive as the Chief Executive Officer of a corporation whose

-6-

equity securities are regularly traded on a recognized public market; (ii) a material reduction in the Executive’s annual Base Salary or Target Annual Incentive, other than a reduction made prior to a Change of Control that in the aggregate does not exceed 10% that also is applied to substantially all of the Company’s other senior executives; or (iii) the relocation of the Executive’s principal place of performing his duties as an employee of the Company by more than thirty (30) miles. Notwithstanding the foregoing, an event described in this Section shall not constitute Good Reason unless it is communicated by the Executive to the Company in writing within ninety (90) days of the initial existence of such event and is not corrected by the Company in a manner which is reasonably satisfactory to such Executive (including full retroactive correction with respect to any reduction in annual Base Salary or Target Annual Incentive except as permitted in clause (ii)) within thirty (30) days of the Company’s receipt of such written notice. In any event, Executive’s Separation from Service must occur during the two (2) year period following the initial existence of any of the events described in this Section in order to constitute a Separation from Service for Good Reason. The failure of the Company’s stockholders to elect or reelect Executive to the Board will not constitute Good Reason for purposes of this Agreement.

(e) Continuance Period. For purposes of this Agreement, “Continuance Period” will mean the period of time beginning on the date of the termination of Executive’s employment and ending on the date on which Executive is no longer receiving Base Salary payments under Section 7.

(f) In Connection with a Change of Control. For purposes of this Agreement, a termination of Executive’s employment with the Company is “in Connection with a Change of Control” if Executive’s employment is terminated (i) within two (2) months preceding a Change of Control or (ii) within twelve (12) months following a Change of Control.

11. Indemnification and Insurance. Executive will be covered under the Company’s insurance policies and, subject to applicable law, will be provided indemnification to the maximum extent permitted by the Company’s bylaws, Certificate of Incorporation, and standard form of Indemnification Agreement, with such insurance coverage and indemnification to be in accordance with the Company’s standard practices for senior executive officers but on terms no less favorable than provided to any other Company senior executive officer or director.

12. Confidential Information. Executive has previously executed the Company’s standard form of employee confidential information agreement (the “Confidential Information Agreement”). During the Employment Term, Executive further agrees to execute any updated versions of the Confidential Information Agreement (any such updated version also referred to as the “Confidential Information Agreement”) as may be required of substantially all of the Company’s executive officers.

13. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors, and legal representatives of Executive upon Executive’s death and (b) any successor of the Company. Except for purposes of Section 8(b), any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose, “successor” means any person, firm, corporation, or other

-7-

business entity which at any time, whether by purchase, merger, or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company. None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance, or other disposition of Executive’s right to compensation or other benefits will be null and void.

14. Notices.

15. Severability. If any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable, or void, this Agreement will continue in full force and effect without said provision.

16. Arbitration.

(a) General. In consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes, and Executive’s receipt of the compensation and other benefits paid to Executive by the Company, at present and in the future, Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any employee, officer, director, shareholder, or benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise or the termination of Executive’s service with the Company, including any breach of this Agreement, will be subject to binding arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the “Rules”) and pursuant to California law. Disputes which Executive agrees to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under state or federal law, including, but not limited to, claims under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the California Fair Employment and Housing Act, the California Labor Code, claims of harassment, discrimination, or wrongful termination, and any statutory claims. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive.

-8-

(b) Procedure. Executive agrees that any arbitration will be administered by the American Arbitration Association (“AAA”) and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. The arbitration proceedings will be held in Marin County, California and will allow for discovery according to the rules set forth in the National Rules for the Resolution of Employment Disputes or California Code of Civil Procedure. Executive agrees that the arbitrator will have the power to decide any motions brought by any party to the arbitration, including motions for summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. Executive agrees that the arbitrator will issue a written decision on the merits. Executive understands the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive will pay the first $200.00 of any filing fees associated with any arbitration Executive initiates. Executive agrees that the arbitrator will administer and conduct any arbitration in a manner consistent with the Rules and that to the extent that the AAA’s National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules will take precedence.

(c) Remedy. Except as provided by the Rules, arbitration will be the sole, exclusive, and final remedy for any dispute between Executive and the Company. Accordingly, except as provided for by the Rules, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator will not order or require the Company to adopt a policy not otherwise required by law which the Company has not adopted.

(d) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional relief, Executive agrees that any party also may petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement or any other agreement regarding trade secrets, confidential information, Nonsolicitation or Labor Code §2870.

(e) Administrative Relief. Executive understands that this Agreement does not prohibit Executive from pursuing an administrative claim with a local, state, or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission, or the workers’ compensation board. This Agreement does, however, preclude Executive from pursuing court action regarding any such claim.

(f) Voluntary Nature of Agreement. Executive acknowledges and agrees that Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has carefully read this Agreement and that Executive has asked any questions needed for Executive

-9-

to understand the terms, consequences, and binding effect of this Agreement, including that Executive is waiving Executive’s right to a jury trial. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice before signing this Agreement.

17. Legal and Tax Expenses. The Company will directly pay Executive’s counsel up to $2,500 for reasonable legal and tax advice expenses incurred in connection with amendment and restatement of this Agreement in December 2008. Such payment shall be made in full within 30 days after the Company’s receipt of any applicable invoices (and in any event by not later than December 31, 2009).

18. Integration. This Agreement represents the entire agreement and understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral, other than the Program. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding unless in a writing that specifically references this Section and is signed by duly authorized representatives of the parties hereto.

19. Waiver of Breach. The waiver of a breach of any term or provision of this Agreement, which must be in writing, will not operate as or be construed to be a waiver of any other previous or subsequent breach of this Agreement.

20. Survival. The Confidential Information Agreement, the Company’s and Executive’s responsibilities under Sections 6, 7, 10, 13, 15 and 16 will survive the termination of this Agreement.

21. Headings. All captions and section headings used in this Agreement are for convenient reference only and do not form a part of this Agreement.

22. Tax Withholding. All payments made pursuant to this Agreement will be subject to withholding of applicable taxes.

23. Governing Law. This Agreement will be governed by the laws of the State of California (with the exception of its conflict of laws provisions).

24. Acknowledgment. Executive acknowledges that she has had the opportunity to discuss this matter with and obtain advice from his private attorney, has had sufficient time to, and has carefully read and fully understands all the provisions of this Agreement, and is knowingly and voluntarily entering into this Agreement.

25. Counterparts. This Agreement may be executed in counterparts, and each counterpart will have the same force and effect as an original and will constitute an effective, binding agreement on the part of each of the undersigned.
