                            (d)     Commencement Date.  The Executive commenced full-time Employment on October 31, 2005.

                    2.     Cash and Incentive Compensation.

                            (a)     Salary.  The Company shall pay the Executive as compensation for his services a base salary at a gross annual rate of $230,000, payable in accordance with the Company’s standard payroll schedule.  The compensation specified in this Subsection (a), together with any adjustments by the Company from time to time, is referred to in this Agreement as “Base Salary.”

                            (b)     Target Bonus.  The Executive shall be eligible to participate in an annual bonus program that will provide him with an opportunity to earn a potential annual bonus equal to 60.0% of the Executive’s Base Salary.  The amount of the bonus shall be based upon the performance of the Executive, as set by the individual performance objectives described in this Subsection, and the Company in each calendar year, and shall be paid by no later than January 31 of the following year, contingent on the Executive remaining employed by the Company as of such date.  The Executive’s individual performance objectives and those of the Company’s shall be set by the CEO after consultation with the Executive by no later than March 31, of each calendar year.  For calendar year 2005, the Executive’s bonus shall be prorated based on the number of days of such year that the Executive was employed by the Company.  Any bonus awarded or paid to the Executive will be subject to the discretion of the Board. 

                            (c)     Stock Options.  The Executive shall be eligible for an annual incentive stock option grant subject to the approval of the Board.  The per share exercise price of the option will be equal to the per share fair market value of the common stock on the date of grant, as determined by the Board of Directors.  The term of such option shall be ten (10) years, subject to earlier expiration in the event of the termination of the Executive’s Employment.    The Executive shall vest in 25% of the option shares after the first twelve (12) months of continuous service and shall vest in the remaining option shares in equal monthly installments over the next three (3) years of continuous service.  The grant of each such option shall be subject to the other terms and conditions set forth in the Company’s 2005 Incentive Plan and in the Company’s standard form of stock option agreement. 

                    3.     Vacation and Executive Benefits.  During the term of his Employment, the Executive shall be eligible for 17 days vacation per year, in accordance with the Company’s standard policy for senior management, as it may be amended from time to time.  During the term of his Employment, the Executive shall be eligible to participate in any employee benefit plans maintained by the Company for senior management, subject in each case to the generally applicable terms and conditions of the plan in question and to the determinations of any person or committee administering such plan.

                    4.     Business Expenses.  During the term of his Employment, the Executive shall be authorized to incur necessary and reasonable travel, entertainment and other business expenses in connection with his duties hereunder.  The Company shall reimburse the Executive for such expenses upon presentation of an itemized account and appropriate supporting documentation, all in accordance with the Company’s generally applicable policies.

                    5.     Term of Employment.

                            (a)     Basic Rule.  The Company agrees to continue the Executive’s Employment, and the Executive agrees to remain in Employment with the Company, from the commencement date set forth in Section 1(d) until the date when the Executive’s Employment terminates pursuant to Subsection (b) below.  The Executive’s Employment with the Company shall be “at will,” and either the Executive or the Company may terminate the Executive’s Employment at any time, for any reason, with or without Cause.  Any contrary representations, which may have been made to the Executive shall be superseded by this Agreement.  This Agreement shall constitute the full and complete agreement between the Executive and the Company on the “at will” nature of the Executive’s Employment, which may only be changed in an express written agreement signed by the Executive and a duly authorized officer of the Company.

                            (b)     Termination.  The Company may terminate the Executive’s Employment at any time and for any reason (or no reason), and with or without Cause, by giving the Executive notice in writing.  The Executive may terminate his Employment by giving the Company fourteen (14) days advance notice in writing.  The Executive’s Employment shall terminate automatically in the event of his death or Permanent Disability.  For purposes of this Agreement, “Permanent Disability” shall mean that the Executive has become so physically or mentally disabled as to be incapable of satisfactorily performing the duties under this Agreement for a period of one hundred eighty (180) consecutive calendar days.

                            (c)     Rights Upon Termination.  Except as expressly provided in Section 6, upon the termination of the Executive’s Employment pursuant to this Section 5, the Executive shall only be entitled to the compensation, benefits and reimbursements described in Sections 2, 3 and 4 for the period preceding the effective date of the termination.  The payments under this Agreement shall fully discharge all responsibilities of the Company to the Executive.

                            (b)     Termination without Cause.  If, during the term of this Agreement, and not in connection with a Change of Control as addressed in Subsection (c) below, the Company terminates Executive’s employment without Cause or due to Permanent Disability or Executive resigns for Good Reason, then:

                            (i)     the Executive shall immediately vest in an additional number of shares under all outstanding options as if he had performed twelve (12) additional months of service; and

                            (a)     Notice.  Notices and all other communications contemplated by this Agreement shall be in writing and shall be deemed to have been duly given when personally delivered or when mailed by overnight courier, U.S. registered or certified mail, return receipt requested and postage prepaid.  In the case of the Executive, mailed notices shall be addressed to him at the home address which he most recently communicated to the Company in writing.  In the case of the Company, mailed notices shall be addressed to its corporate headquarters, and all notices shall be directed to the attention of its Secretary.

                            (b)     Modifications and Waivers.  No provision of this Agreement shall be modified, waived or discharged unless the modification, waiver or discharge is agreed to in writing and signed by the Executive and by an authorized officer of the Company (other than the Executive).  No waiver by either party of any breach of, or of compliance with, any condition or provision of this Agreement by the other party shall be considered a waiver of any other condition or provision or of the same condition or provision at another time.

                            (c)     Whole Agreement.  No other agreements, representations or understandings (whether oral or written) which are not expressly set forth in this Agreement have been made or entered into by either party with respect to the subject matter of this Agreement.  This Agreement and the Proprietary Information and Inventions Agreement contain the entire understanding of the parties with respect to the subject matter hereof.

                            (d)     Withholding Taxes.  All payments made under this Agreement shall be subject to reduction to reflect taxes or other charges required to be withheld by law.

                            (f)     Severability.  The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision hereof, which shall remain in full force and effect.

                            (g)     Arbitration.  Each party agrees that any and all disputes which arise out of or relate to the Executive’s employment, the termination of the Executive’s employment, or the terms of this Agreement shall be resolved through final and binding arbitration.  Such arbitration shall be in lieu of any trial before a judge and/or jury, and the Executive and Company expressly waive all rights to have such disputes resolved via trial before a judge and/or jury.  Such disputes shall include, without limitation, claims for breach of contract or of the covenant of good faith and fair dealing, claims of discrimination, claims under any federal, state or local law or regulation now in existence or hereinafter enacted and as amended from time to time concerning in any way the subject of the Executive’s employment with the Company or its termination.  The only claims not covered by this Agreement to arbitrate disputes are:  (i) claims for benefits under the unemployment insurance benefits; (ii) claims for workers’ compensation benefits under any of the Company’s workers’ compensation insurance policy or fund; (iii) claims arising from or relating to the non-competition provisions of this Agreement; and (iv) claims concerning the validity, infringement, ownership, or enforceability of any trade secret, patent right, copyright, trademark or any other intellectual property right, and any claim pursuant to or under any existing confidential/proprietary/trade secrets information and inventions agreement(s) such as, but not limited to, the Proprietary Information and Inventions Agreement.  With respect to such disputes, they shall not be subject to arbitration; rather, they will be resolved pursuant to applicable law.

                    Arbitration shall be conducted in accordance with the National Rules for the Resolution of Employment Disputes of the American Arbitration Association (“AAA Rules”), provided, however, that the arbitrator shall allow the discovery authorized by California Code of Civil Procedure section 1282, et seq., or any other discovery required by applicable law in arbitration proceedings, including, but not limited to, discovery available under the applicable state and/or federal arbitration statutes.  Also, to the extent that any of the AAA Rules or anything in this arbitration section conflicts with any arbitration procedures required by applicable law, the arbitration procedures required by applicable law shall govern.

                    Arbitration will be conducted in Santa Clara County, California or, if the Executive does not reside within 100 miles of Santa Clara County at the time the dispute arises, then the arbitration may take place in the largest metropolitan area within 50 miles of the Executive’s place of residence when the dispute arises.

                    During the course of the arbitration, the Executive and the Company will each bear equally the arbitrator’s fee and any other type of expense or cost of arbitration, unless applicable law requires otherwise, and each shall bear their own respective attorneys’ fees incurred in connection with the arbitration.  The arbitrator will not have authority to award attorneys’ fees unless a statute or contract at issue in the dispute authorizes the award of attorneys’ fees to the prevailing party. In such case, the arbitrator shall have the authority to make an award of attorneys’ fees as required or permitted by the applicable statute or contract.  If there is a dispute as to whether the Executive or the Company is the prevailing party in the arbitration, the arbitrator will decide this issue.

                    The arbitrator shall issue a written award that sets forth the essential findings of fact and conclusions of law on which the award is based.  The arbitrator shall have the authority to award any relief authorized by law in connection with the asserted claims or disputes.  The arbitrator’s award shall be subject to correction, confirmation, or vacation, as provided by applicable law setting forth the standard of judicial review of arbitration awards.  Judgment upon the arbitrator’s award may be entered in any court having jurisdiction thereof.

                            (h)     No Assignment.  This Agreement and all rights and obligations of the Executive hereunder are personal to the Executive and may not be transferred or assigned by the Executive at any time.  The Company may assign its rights under this Agreement to any entity that assumes the Company’s obligations hereunder in connection with any sale or transfer of all or a substantial portion of the Company’s assets to such entity.

                            (i)     Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

[The remainder of this page intentionally left blank.]

                    IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the case of the Company by its duly authorized officer, as of the day and year first above written.

EMPLOYEE PROPRIETARY INFORMATION
AND INVENTIONS AGREEMENT

        In consideration of my employment or continued employment by ALIGN TECHNOLOGY, INC. (the “Company”), and the compensation now and hereafter paid to me, I hereby agree as follows:

1.     PROPRIETARY INFORMATION.  At all times during my employment and thereafter, I will hold in strictest confidence and will not disclose, use, lecture upon or publish any of the Company’s Proprietary Information (defined below), except as such disclosure, use or publication may be required in connection with my work for the Company, or unless an officer of the Company expressly authorizes such in writing.  “Proprietary Information” shall mean any and all confidential and/or proprietary knowledge, data or information of the Company, its affiliated entities, customers and suppliers, including but not limited to information relating to products, processes, know-how, designs, formulas, methods, developmental or experimental work, improvements, discoveries, inventions, ideas, source and object codes, data, programs, other works of authorship, and plans for research and development.  During my employment by the Company I will not improperly use or disclose any confidential information or trade secrets, if any, of any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto the premises of the Company any unpublished documents or any property belonging to any former employer or any other person to whom I have an obligation of confidentiality unless consented to in writing by that former employer or person.

2.     Assignment of Inventions.

        2.1.     Proprietary Rights.  The term “Proprietary Rights” shall mean all trade secret, patent, copyright, mask work and other intellectual property rights throughout the world.

        2.2.     Inventions. The term “Inventions” shall mean all trade secrets, inventions, mask works, ideas, processes, formulas, source and object codes, data, programs, other works of authorship, know-how, improvements, discoveries, developments, designs and techniques.

        2.3.     Prior Inventions. I have set forth on Exhibit B (Previous Inventions) attached hereto a complete list of all Inventions that I have, alone or jointly with others, made prior to the commencement of my employment with the Company that I consider to be my property or the property of third parties and that I wish to have excluded from the scope of this Agreement (collectively referred to as “Prior Inventions”).  If no such disclosure is attached, I represent that there are no Prior Inventions.  If, in the course of my employment with the Company, I incorporate a Prior Invention into a Company product, process or machine, the Company is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights to sublicense through multiple tiers of sublicensees) to make, have made, modify, use and sell such Prior Invention.  Notwithstanding the foregoing, I agree that I will not incorporate, or permit to be incorporated, Prior Inventions in any Company Inventions without the Company’s prior written consent.

        2.4.     Assignment of Inventions.  Subject to Section 2.6 and except for those Inventions which I can prove qualify fully under the provisions of California Labor Code 2870 (as set forth in Exhibit A), I hereby assign and agree to assign in the future (when any such Inventions or Proprietary Rights are first reduced to practice or first fixed in a tangible medium, as applicable) to the Company all my right, title and interest in and to any and all Inventions (and all Proprietary Rights with respect thereto).  I will, at the Company’s request, promptly execute a written assignment to the Company of any such Company Invention, and I will preserve any such Invention as part of the Proprietary Information of the Company (the “Company Inventions”). 

        2.5.     Obligation to Keep Company Informed.  I will promptly and fully disclose in writing to the Company all Inventions during my employment and for one (1) year after my employment, including any that may be covered by Section 2870.  I agree to assist in every proper way and to execute those documents and take such acts as are reasonably requested by the Company to obtain, sustain and from time to time enforce patents, copyrights and other rights and protections relating to Inventions in the United States or any other country.

        2.6.     Government or Third Party.  I also agree to assign all my right, title and interest in and to any particular Company Invention to a third party, including without limitation the United States, as directed by the Company.

3.     NO CONFLICTING OBLIGATION.  I REPRESENT that my performance of all the terms of this Agreement and as an employee of the Company does not and will not breach any agreement to keep in confidence information acquired by me in confidence or in trust prior to my employment by the Company.  I have not entered into, and I agree I will not enter into, any agreement either written or oral in conflict herewith.

4.     RETURN OF COMPANY DOCUMENTS.  Upon termination of my employment with the Company for any reason whatsoever, voluntarily or involuntarily, and at any earlier time the Company requests, I will deliver to the person designated by the Company all originals and copies of all documents and other property of the Company in my possession, under my control or to which I may have access.  I will not reproduce or appropriate for my own use, or for the use of others, any property, Proprietary Information or Company Inventions.

5.     LEGAL AND EQUITABLE REMEDIES.  Because my services are personal and unique and because I may have access to and become acquainted with the Proprietary Information of the Company, the Company shall have the right to enforce this Agreement and any of its provisions by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that the Company may have for a breach of this Agreement.

6.     NOTICES.  Any notices required or permitted hereunder shall be given to the appropriate party at the address specified below or at such other address as the party shall specify in writing.  Such notice shall be deemed given upon personal delivery to the appropriate address or if sent by certified or registered mail, three (3) days after the date of mailing.

GENERAL PROVISIONS.  This Agreement will be governed by and construed according to the laws of the State of California, as such laws are applied to agreements entered into and to be performed entirely within California between California residents.  In case any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect the other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.  This Agreement will be binding upon my heirs, executors, administrators and other legal representatives and will be for the benefit of the Company, its successors, and its assigns.  The provisions of this Agreement shall survive the termination of my employment and the assignment of this Agreement by the Company to any successor in interest or other assignee.  No waiver by the Company of any breach of this Agreement shall be a waiver of any preceding or succeeding breach.  No waiver by the Company of any right under this Agreement shall be construed as a waiver of any other right.  The obligations pursuant to Sections 1 and 2 of this Agreement shall apply to any time during which I was previously employed, or am in the future employed, by the Company as a consultant if no other agreement governs nondisclosure and assignment of inventions during such period.  This Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matter hereof and supersedes and merges all prior discussions between us.  No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, will be effective unless in writing and signed by the party to be charged.  Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.

          This Agreement shall be effective as of the first day of my employment with the Company.
