The undersigned:

and

have agreed to the following lease:

1

This initial rent is calculated as follows:

If rent not subject to sales tax has been agreed, the lessee will owe the lessor in addition to the rent a separate payment by way of compensation for the loss that the lessor or its successor(s) in title suffer(s) or will suffer because the sales tax on the investments and operating costs of the lessor are not or no longer deductible. The provisions of 19.1 to 19.9 of the general conditions will then not be applicable.

2

In words: Twenty nine thousand six hundred and twenty six euro and fifty four cents.

The advance payment for additional supplies and services is 30 euro per square meter per year, exclusive of VAT.

The parties agree that the following additional supplies and services will be provided by or on behalf of the lessor:

The amount of the bank guarantee referred to in 12.1 of the general conditions is hereby set by the parties at € 29,626.54

in words: twenty nine thousand six hundred and twenty six euro and fifty four cents.

The lessee will submit this bank guarantee to the lessor no later than 1 October 2011. Following receipt of the aforementioned bank guarantee, the present bank guarantee will be returned to the lessee within 10 working days. This bank guarantee is to be provided in conformance with the model defined by the Raad voor Onroerende Zaken (Council for Real Estate Matters, at a banking institution recognized in the Netherlands.

The lessee receives a rent discount for the first rent period that is equal to 8 months rent-free. This rent-free period will be divided evenly over the entire rental period. Therefore the lessee will receive 1 1/3 rent-free months per year.

Upon commencement of the lease or on the date of delivery of the leased space, if earlier, a delivery report will be drawn up, which should be signed by the lessee and the lessor.

The leased space is delivered in its present state, including:

Before the commencement date of the lease, the lessor will be responsible for partitioning the office space. The costs of partitioning the office space will be borne by the lessor. Lessor commits to placing the partitions at as early a date as possible.

The lessee has the right, at his own expense and risk, to create one or more restrooms in the communal space on the 6^th floor (opposite the present restrooms, as indicated on the floor plan). This requires the written approval of the lessor, who will not refuse or delay this approval on unreasonable grounds. At the end of the lease, the restrooms may be left behind in the state that they will be in at that time, provided they are clean and in working order.

The lessor makes available to the lessee a one-time financial contribution equal to 7 months’ rent plus VAT. This contribution is to be used for lessee investments in the leased space, such as partition walls, flooring, furniture, data cabling, or lessee lessee investments. If the total amount of lessee investments exceeds the aforementioned amount, the excess will be the responsibility of the lessee. The aforementioned contribution will be paid by the lessor to the lessee after signature of the original lease, provision of the bank guarantee and payment of the first rent invoice and once the lessee has made the relevant invoices available to the lessor.

The lessee has the possibility, following signature of the lease and the provision of the bank guarantee, to carry out work or have work carried out in the leased space. If this work is completed before the commencement date of the lease, the lessee has the right to take possession of the leased space. This will never lead to an earlier lease commencement date.

The lessee has the possibility of adjusting the fixtures and fittings of the leased space. This requires the written consent of the lessor, who will not refuse to give this consent on unreasonable grounds. Adjustments are to be performed by recognized installers.

At the end of the lease, the lessee will be obliged to deliver the leased space empty and vacant, free of fixtures and fittings such as partition walls, carpet, cabling, pantries and other items that do not belong to the leased space. The lessee is also obliged to have damage to the leased space, other than as a result of normal wear and tear, professionally repaired.

The lessee will ensure that Lionbridge Technologies Holdings B.V. will irrevocably and unconditionally guarantee everything that the lessee will owe pursuant to the aforementioned lease, including any explicit or automatic extension and/or change to it and, further, including interest and/or charges. All this will be in accordance with the “concern guarantee” model attached to this lease. A copy of this concern guarantee will be attached as an appendix to this lease.

In signing this contract, the present lease between Lionbridge Technologies B.V. and IEF (Vastgoed) Pluto B.V., commencement date July 1, 2007, will be unconditionally terminated as of October 1, 2011, on condition that the lessee has fulfilled all its obligations (including signature of the new original lease, provision of the bank guarantee, the first rental payment, and signature of the delivery report by the lessee) resulting from the present lease (July 1, 2007), with the exception of the final settlement of service charges, which the lessee will pay later.

The lessee has the right to deliver to the lessor the present rented space on the fifth floor, vacant and swept clean but including partition walls, flooring, data cabling, and similar.

The lessee is aware that his details, in so far as these are important to the present lease, are included in the lessee file of both the lessor and its manager from the date of signature of this agreement. This file is intended to establish and implement the rights and obligations of the lessee and the lessor.

The lessee hereby guarantees to the lessor that any inspections of the leased space before or upon commencement of the lease and before and upon delivery of the leased space at the end of the lease will be attended on behalf of the lessee by one or more appropriately authorized representative(s) and that the description of the leased space as referred to in 1.1 and the official reports of delivery mentioned in 1 and 10 of the general provisions and possibly other comparable documents will be signed by persons who are duly authorized to do so on behalf of the lessee.
