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

                              (a)  Position.  For the term of her employment
    under this Agreement ("Employment"), the Company agrees to employ the
    Executive in the position of Vice President, Human Resources. The Executive
    shall report to the Chief Executive Officer (the "CEO"). The Executive
    accepts such employment and agrees to discharge all of the duties normally
    associated with said position, and to faithfully and to the best of her
    abilities perform such other services consistent with her position as Vice
    President, Human Resources as may from time to time be assigned to him by
    the CEO.

    of her Employment, the Executive shall devote her full business efforts and
    time to the Company. 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 CEO, provided,
    however, that the Executive may, without the approval of the CEO, serve in
    any capacity with any civic, educational or charitable organization. The
    Executive may own, as a passive investor, no more than one percent (1%) of
    any class of the outstanding securities of any publicly traded corporation.

                              (c)  No  Conflicting  Obligations.  The  Executive
    represents and warrants to the Company that she is under no obligations or
    commitments, whether contractual or otherwise, that are inconsistent with
    her obligations under this Agreement. The Executive represents and warrants
    that she will not use or disclose, in connection with her employment by the
    Company, any trade secrets or other proprietary information or intellectual
    property in which the Executive or any other person has any right, title or
    interest and that her employment by the Company as contemplated by this
    Agreement will not infringe or violate the rights of any other person or
    entity. The Executive represents and warrants to the Company that she has
    returned all property and confidential information belonging to any prior
    employers.

                              (d)  Commencement  Date. The Executive  commenced
    full-time Employment on September 25, 2006.

                  2.       Cash and Incentive Compensation.

                              (a)  Salary.  The Company shall pay the Executive
    as compensation for her services a base salary at a gross annual rate of
    $250,000, 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 her
    with an opportunity to earn a potential annual bonus equal to 60% 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. Any bonus awarded or paid to
    the Executive will be subject to the discretion of the Board; provided,
    however, that for calendar year 2006, the Company guarantees that Executive
    will be paid a prorated bonus based on the number of days of such year that
    the Executive was employed by the Company equal to $37,500.

                              (c)  Incentive  Awards.  The  Executive  shall be
    eligible for an annual incentive stock option grant and/or restricted stock
    unit award 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. Each restricted stock unit award vests 25% on the one
    year anniversary of the date of grant with 6.25% vesting quarterly
    thereafter. The grant of each such option and/or restricted stock unit 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
    and restricted stock unit agreement, as applicable.

                  3.       Vacation and Executive Benefits. During the term of
                           -------------------------------
her 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 her 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 her Employment,

                  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.

    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 her Employment by giving the Company fourteen (14)
    days advance notice in writing. The Executive's Employment shall terminate
    automatically in the event of her 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

    Employment pursuant to this Section 5, the Executive shall only be entitled

    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.

                              (d)  Termination of Agreement.  The  termination
    of this Agreement shall not limit or otherwise affect any of the Executive's
    obligations under Section 7.

    of the State of California (except provisions governing the choice of law).

                              (f)  Severability. The invalidity or
    unenforceability of any provision or provisions of this Agreement shal 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.

                                       7.


                  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.]

                                       8.


                  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.

                                    ---------

                PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT
                                   (ATTACHED)

                                       10.


                             ALIGN TECHNOLOGY, INC.

                        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.

                                       11.


         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.

7.       EMPLOYMENT. I agree and understand that nothing in this Agreement shall
confer any right with respect to continuation of employment by the Company, nor
shall it interfere in any way with my right or the Company's right to terminate
my employment at any time, with or without cause.

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.

                                       12.


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

                         LIMITED EXCLUSION NOTIFICATION

         THIS IS TO NOTIFY you in accordance with Section 2872 of the California
Labor Code that the foregoing Agreement between you and the Company does not
require you to assign or offer to assign to the Company any invention that you
developed entirely on your own time without using the Company's equipment,
supplies, facilities or trade secret information except for those inventions
that either:

         1.       Relate at the time of conception or reduction to practice of
the invention to the Company's business, or actual or demonstrably anticipated
research or development of the Company;

         2.       Result from any work performed by you for the Company.

To the extent a provision in the foregoing Agreement purports to require you to
assign an invention otherwise excluded from the preceding paragraph, the
provision is against the public policy of this state and is unenforceable.

         This limited exclusion does not apply to any patent or invention
covered by a contract between the Company and the United States or any of its
agencies requiring full title to such patent or invention to be in the United
States.

         I ACKNOWLEDGE RECEIPT of a copy of this notification.
