Dear Dave:

        On behalf of Align Technology, Inc. (the "Company"), I am extremely
pleased to invite you to become a member of the Company's Board of Directors
(the "Board"). We believe that your skills, expertise and knowledge will prove
very helpful to the Company's progress.

        In connection with your service as a director, we will recommend to the
Board that you be granted a stock option entitling you to purchase up to 75,000
shares of the Company's Common Stock. We will recommend that the shares become
vested as follows: 25% of the option shall vest on the 12 month anniversary of
the commencement of your service as a director, and the remaining 75% shall vest
in 36 equal monthly installments. In addition, the option will fully accelerate
upon the occurrence of a Change in Control of the Company (as that term is
defined in the Company's 2001 Stock Incentive Plan (the "Plan")). Each option
granted to you will be subject to the terms and conditions of the Plan and the
stock option agreement evidencing the option. The exercise price per share will
be equal to the fair market value of the Company's common stock on the date of
grant, as determined by the Board.

        In addition, you will be entitled to receive cash compensation in
accordance with Schedule A attached hereto. You will be reimbursed for
reasonable expenses incurred by you in connection with your services to the
Company in accordance with the Company's established policies.

        The Board currently meets once every two months at our offices in Santa
Clara. The various committees of the Board to which you may be appointed also
meet frequently. It is our expectation that you will participate in those
meetings in person to the extent possible. We also ask that you make yourself
available to participate in various telephonic meetings from time to time.

        Please note that this offer is contingent upon your qualification as an
independent director under applicable NASDAQ rules. Also, please note that this
offer and any rights to purchase shares of the Company's capital stock
referenced in this offer letter are contingent upon approval of the Board and
the Company's stockholders.

        Your service on the Board of Directors will be in accordance with, and
subject to, the Company's Bylaws and the Certificate of Incorporation, as such
may be amended from time to time. In accepting this offer, you are representing
to us that (i) you do not know of any conflict that would restrict you from
becoming a director of the Company and (ii) you will not provide the Company
with any documents, records or other confidential information belonging to any
other parties.

will treat it as such. If you wish to accept this offer, please sign below and

SETTLEMENT AGREEMENT 
 
BETWEEN THE UNDERSIGNED: 
 
Align Technology registered with the Registry of Commerce and Companies of
Paris under number 434.581.278, having its registered office at 29, rue Jean-Jacques Rousseau in Paris (75001), France, and represented by Mr. Jeremy Mosley, Président, duly authorized, 
 
Hereafter “the Company” 
 
ON THE ONE HAND

WHEREAS: 
 

	1.	 	The Employee joined the Company effective on February 1, 2001 in the capacity of Operation Director as an Executive (Cadre) and subject to the National
Collective Bargaining Agreement for trading on dental product. 

 

	2.	 	As of the beginning of 2002, the Company experienced substantial economic difficulties, as the result of the long-term decline in the market for dental prosthesis.
These difficulties, incidentally, were aggravated during all the long of the year 2002. 

 

	3.	 	It was under these circumstances that on September 16, 2002 the Employee was convened to a pre-dismissal meeting held on September 25, 2002.

 
By registered letter with
acknowledgment of receipt dated October 14, 2002, the Employee was terminated for the following economic grounds: 
 
“(...) it has been now several years that our Company is facing important economic difficulties. These difficulties are the
consequence of the recession of the business our Company belongs, i.e.: dental prosthesis. 
 
As a result of this situation, the Group has been facing net losses, which were equal to $37.3 million (around €37.3 million) for the first six months of 2002, including $18.5 million for the
first quarter of 2002 and $18.8 million for the second one. 
 
Currently, our business is in the red and this situation also concerns the French company where you work: it had serious declining cases submissions and revenue through out the fiscal year 2001 and the last half of fiscal year
2002. 
 
Our Company booked revenues, for
the first eight months of this year, were equal only to 15% of the total operating expenses, which means that operating expenses are six times higher than revenues, and case submissions are only 1/3 of the total revised target for the year to date.
As a result, we are in a very critical economic situation. 
 
Because of these difficulties, and because of the pronounced fall off of the French company revenues, we are obliged to proceed to a reorganization under jeopardy of our business and Company in the short term. 
 
In this conditions, we have to suppress your job of
Operations Director which is no longer justified with respect of the new organization needed by the situation described above.” 
 

	4.	 	By letter with acknowledge of receipt, date November 7, 2002, the Employee immediately notified the Company that he disputed the motive for his termination, and that
he considered this termination wrongful, absent of any real and serious cause, and severely damagingly to his professional image.

The Employee stated that he
believed he had suffered professional, moral and material prejudice he deems reparable by the payment of an indemnity in the total amount of one hundred thousand euro (€100,000). 
 

	5.	 	For its part, the Company believes that the Employee’s termination is justified to the extent that the economic difficulties it has encountered are manifestly
exhibited. 

 
In this respect, the
Company announced that the pursuit of contractual relations with the Employee had become impossible given, in particular, the elimination of his position as Operations Direction and the absence of any available position that would permit the
reassignment of the Employee within the Align group. 
 
Finally, the Company disputed the totality of grievances evoked by the Employee and the excessive amount of the indemnity the latter is seeking in compensation for the prejudice he believes he has suffered. 
 

	6	 	Nevertheless, the Parties, desiring to settle amicably the dispute arising from the Employee’s termination, have decided, after each seeking separate counsel,
to make reciprocal concessions and have agreed, in application of Articles 2044 to 2058 of the French Civil Code, to settle the litigation that opposes them through a transaction. 

 
The Employee furthermore confirms that his consent for this
agreement was given in an entirely free and enlightened manner. 
 
 
IT IS HEREBY AGREED AS FOLLOWS: 
 
ARTICLE 1: 
 

	1.1	 	The Employee acknowledges receipt of his termination letter on October 15, 2002. 

 

	1.2	 	The Employee acknowledges that, according to his dismissal letter provisions, his 6-month notice period has commenced only on November 1, 2002 and that the Company
has decided to release him from the completion of his notice period effective on the said date. Consequently, and according to French Labor law, the effective date of the breach of the Employee’s employment contract will April 30, 2003. On this
date, the Company will deliver to the Employee his work certificate (Certificat de Travail). 

 

	1.3	 	During the course of the notice period of the Employee, and for practical reasons and follow up of the files, the Company could solicit and/or ask him, punctually,
to come in its premises, what the Employee specifically accepts. In the event the Company requests the Employee to come in its premises, a 5-days notice period should be respected.

ARTICLE 2: 
 
The Employee shall receive, within ten days of signature at the latest of
this agreement, his ASSEDIC certificate, a summary of his salary as well as the outstanding balance of any accounts, including the following items:

	-	 	An indemnity in compensation of notice period in the total gross amount of eighty-three thousand five hundred and thirty-four euros and zero four cents
(€283,534.04); 

 

	-	 	An indemnity in compensation of outstanding paid vacation days in the total gross amount of twenty-five thousand nine hundred and nineteen euros and twenty three
cents (€25,919.23). 

 
The compensation used as
a base for calculating the various indemnities mentioned above is the average of salary, commission and bonuses paid to the Employee over the course of the past twelve months, to which the Employee hereby expressly acknowledges. 
 
The sums described above, except the dismissal indemnity, shall be paid to
Employee after deduction of the employee portion of social charges and CSG-CRDS. 
 
 
ARTICLE 3: 
 

	3.1	 	To put an end to all litigation relating to the execution or termination of his employment contract, and in reparation of each of the different prejudices evoked by
the Employee, as a one-time lump-sum payment of all sums, of any kind whatsoever, including those that may have been overlooked, the Company agrees to: 

 

	 	-	 	transfer, upon the signature of the present Settlement agreement, the title of the car provided to the Employee for the purposes of his functions. The net accounting
value of the car is equal to twenty seven thousand nine hundred and five euros (€27,905); 

 

	 	-	 	pay the Employee a settlement indemnity, in the definitive lump-sum amount of forty-four thousand euro (€44,000) before deduction of CSG-CRDS applicable to this
indemnity and to the net accounting value of the car, in conformance with applicable law.

Consequently, the Employee
recognizes that he will receive a net settlement indemnity in the amount of thirty eight thousand three hundred and sixty euro and seventy-eight cents (€38,360.78). 
 

	3.2	 	It is understood that this payment is designed to remedy the damage to career and reputation claimed by the Employee, provided however that it shall not under any
circumstances constitute an acknowledgment by the Company that termination of his employment contract was unlawful. 

 

	3.3	 	This settlement indemnity, one-time and definitive in nature, net of CSG-CRDS, shall be paid to the Employee upon signature of this agreement and in the form of a
Company cheque. 

 
The car’s
different documents will be delivered to the Employee upon the signature of this agreement. Reciprocally the Employee promises to do, without delay, all the formalities issued by the car transfer on his proper name, namely regarding insurance.
