Dear Mr Loh,

This Employment Agreement is an amendment to the December 9, 2005 agreement and sets forth the terms and conditions under which Veeco Asia Pte. Ltd (hereinafter called “the Company”) employs you as Senior Vice President and General Manager in APAC effective December 12, 2005 and under which you accept such employment with the Company.

1.Reporting Relationship

You will report to the Executive Vice President Worldwide Sales in the U.S., or his/her designees, or to such other persons as the Company may notify you in writing.

It is understood and agreed that the Company shall have the right to reassign you to another position with the Company or one of its affiliates from time to time in the future.  The duties you will have in connection with any position to which you are assigned in the future, and your reporting responsibilities in such a position, will be communicated to you at the time you are advised of any new position.

2.Place & Hours of Work

Your place of work will be Singapore. All of the authorities and duties to be performed by the Employee pursuant to this Agreement shall be performed within the APAC region. You agree that you will be required to travel outside the place of posting and to other places, both in China and abroad, as part of your work for the Company.  You also expressly agree that the Company may assign your employment agreement to any of the Company’s subsidiaries or affiliates, in Singapore or any other location, at the Company’s option, according to your capacities.

The normal work hours are from 9:00 a.m. to 6:00 p.m., from Monday to Friday inclusive, of which one (1) hour break is extended for lunch.  You may be required to work additional hours, over weekends or on public holidays as required by your job function and responsibilities and without additional compensation.

3.Representations by Employee

You represent that, to the best of your knowledge, you have no contractual or other commitments to former employers or other entities which would restrict you from joining the Company or performing your regular job duties under this Agreement.   In case you breach this agreement without good cause, the Company will hold you liable for expenses and damages incurred in connection with your recruitment.

You also warrant that you will not, during your employment with the Company, improperly use or disclose any proprietary information or trade secrets belonging to any of your former employers or associates, and will not bring onto the premises of the Company any property of your former employers or associates, if any, unless consented to in writing by those former employers or associates.

4.Remuneration

4.1You will be paid a Basic Salary of 42,060 Singapore Dollars (SGD) per month, payable monthly in arrears (or such other amounts as may from time to time be agreed in writing).  Thereafter, your basic salary shall be subject to annual review in accordance with Company policy, at the sole discretion of the Company.

4.2The Company pays a 13th Month Salary termed as the Annual Wage Supplement (AWS), at the end of the calendar year.  The AWS will be paid on a pro-rata basis for staff with less than one-year service only if they have completed their probation and are not serving any termination notice at the time the AWS is paid out.

4.3The Company will provide a monthly housing allowance to cover your actual housing expenses up to 7,010 (SGD) per month, upon receipt by the Company of proper documentation evidencing such expenditure. To the degree it is possible and preferable, the Company, in its sole discretion, may elect to name itself as the lessor of  such housing, providing you with this benefit without providing the allowance described above.

4.4The Company will also reimburse actual expenses associated with the education of your children (eligible dependents under age 18) with a monthly limit of 3,505 (SGD), upon receipt by the Company of proper documentation evidencing such expenditure.

4.5You will be eligible to participate in the Veeco Annual Management Bonus Plan with a target bonus of 50% of your annual base earnings based on Company and individual performance which is subject to Board of Director approval.  Details outlining your personal business objectives will be communicated to you following commencement of your employment.

4.6You will also be paid a monthly Transport Allowance of 4,085.58 (SGD), payable monthly together with your base salary.

4.7The payment of your salary, bonus and all allowances shall be subject to such statutory deductions as may be required in accordance with applicable legislation in force in Singapore from time to time.

4.8You will be personally responsible to file appropriate income tax returns and pay income tax to the Singapore tax authorities on the remuneration package paid to you under this Agreement.

5.Sick & Hospitalization Leave

In the event of absence or lateness for whatever reason including illness, you shall promptly notify the Company on the first working day of absence.  In the case of absence due to illness greater than five (5) days, you shall provide the Company with a medical certificate from a registered physician certifying your incapacity.  In such circumstances, the Company reserves the right to have you examined by a doctor of its choice.

You will be entitled to take up to fourteen (14) working days paid sick leave during each year of service.  If not taken during the calendar year, these days will not be carried forward to the following year.

6.Annual Leave

You shall be entitled to eighteen (18) days paid vacation leave for each and every full calendar year of employment to be taken at a time or time convenient to, and must be approved by the Company.  You will be allowed to carry forward up to a maximum of five (5) days annual leave to the following year.

7.Employee Benefits

The Company will extend to you and the eligible dependents of your immediate family its personal medical, dental, hospitalization and accident insurance benefits as in effect on the date hereof for employees in similar positions.  These benefits are subject to our current plans and policy guidelines, the details of which will be made available to you following commencement of your employment.  In addition, you will be provided disability insurance (or economic protection/benefits comparable to disability insurance) in amounts and subject to conditions comparable to those afforded to employees of Veeco Instruments Inc., corporate parent of the Company, based in the United States of America.  While the Company presently intends to continue these benefits indefinitely, it reserves the right to amend, modify or discontinue them at any time.

8.Expenses

The Company shall reimburse you for any expenses you incur while engaged in the business of the Company so long as they are reasonable, in the discretion of the Company, and in accordance with the Company’s expense reimbursement policies in effect from time to time, including the requirement to submit on a timely basis proper receipts or other evidence documenting such expenditures.
