1. The term of the sublease shall expire on 31 December 2013.

The sublessee has already waived its right, as provided for in article 43 of Presidential Decree No. 34/1995, to terminate this sublease agreement prior to 16/06/2010.

After 16 December 2010, the sublessee has the right to terminate the sublease agreement at any time, under article 43 of Presidential Decree No. 34/1995. However, the termination shall take effect, in accordance with an amendment to this article, after one (1) year of communication date.

2. The total monthly sublease fee, whose attachment or offsetting for any reason and cause whatsoever, except as provided for herein, is prohibited, is set for the period from 16 November 2007 to 15 December 2007 (16/11/2007-15/12/2007) to Euro twenty five thousand nine hundred and thirty nine and twenty three cents (€ 25,939.23), which shall be increased, on 16 December 2007 and in every following year of lease, as compared to the monthly sublease fee paid in the previous year of lease, by a ratio equal to the increase in the consumer index price, as set forth by the National Statistical Service of Greece for the previous twelve-month period, plus one per cent (1%). Such adjustment shall also apply should the term of the sublease be extended in any way whatsoever.

The above total monthly sublease fee shall be paid within the first five (5) business days of each month of lease at the offices of the sublessor or shall be deposited to a Bank account indicated by the sublessor to the sublessee in writing, whereas payment shall be proved only through the corresponding written receipts issued by the sublessor or the relevant forms issued by the Bank where the deposit is made; any other means of proof, oath included, shall not be accepted.

3. The leased property shall be used by the sublessee for setting up and operating the services of its undertaking or its subsidiary undertakings, or of undertakings in general which are legally associated therewith, and the sublessee shall have the right to cede the use of part of the leased property to them. However, such undertakings shall not acquire any right under this sublease agreement, and the parking spaces shall be used in accordance with their intended use, whereas storage of any flammable or arson materials is prohibited.

4. During the term of the sublease the former party shall make good of any wear or damage to the leased property or its installations which is not caused by poor or normal use on the part of the sublessee.

5. The sublessee has examined the leased property and found it to be in perfect condition and appropriate for its intended use. During the term of the sublease, the

sublessee has the right to modify the movable partitions of the leased floor, at its own expense, upon written consent of the sublessor, providing that the jointly used areas, facades and load-carrying structure of the Second Building are not affected. The sublessee shall be under obligation to restore the leased property to its former state prior to the expiry date of the sublease.

Today the sublessee handed over to the sublessor a drawing of the adjustments to be made on the Second (B) floor of the Second Building. In addition, no later than 10/11/2007, the sublessee shall hand over to the sublessor a drawing of the electrical and mechanical installations. Within five (5) business days, the sublessor shall hand over to the sublessee a list of labor costs and a summary list of conditions, which shall be signed by the contracting parties and shall then be an inseparable part hereof. The contractor’s fee, plus 19% VAT, for the works necessary for the adjustment of the leased property shall be paid to the sublessor as follows: (a) on the date of signature of the above (list of labor costs and summary list of conditions), the sublessee shall pay to the sublessor an amount equal to half of the contractor’s fee, and (b) the balance, plus the VAT calculated on the entire contractor’s fee, within ten (10) days of delivery of the above works. The works shall be accepted based on a certificate of delivery and acceptance. Any construction-related remarks which may be made by the sublessee shall not postpone the acceptance of works, but the sublessor shall be under obligation to make the necessary corrections as soon as possible, should they be in accordance with the agreements made.

In the event that the above adjustment works are carried out, the sublessee shall be under obligation to hand over the leased property to the sublessor, upon expiry of the term of the sublease, as adjusted in accordance with the above.

In any event, the sublessee shall be under obligation to pay the sublease fee, as set forth in clause two (2) hereof.

6. The sublessee shall use the leased property diligently and in accordance with the stipulations laid down herein, in compliance with any obligations relating to leased properties, as arising from the law or from all kinds of applicable provisions, and in particular from Police, Health and City Planning provisions, displaying perfect respect for the property and the fellow tenants of the Building Complex and abiding with all rules of good neighbor relations. The former party, or sublessor, shall under no circumstances be held liable for any violations on the part of the sublessee, as the latter shall be the sole party liable for such violations, and the sublessor shall also have the right to terminate the sublease agreement and evict the sublessee from the leased property, under article 594 of the Civil Code.

7. Any silent renewal or extension of the term of the sublease for any reason whatsoever is strictly prohibited, and should the sublessee stay in the leased property after the expiry date of the above term of the sublease, irrespective of cause, this shall not be considered as a silent renewal or extension. Any lease fee collected by the sublessor during that time shall be considered as compensation for use, but it shall not be interpreted as an express or silent extension of the term of the sublease.

8. Upon expiry of the term of the sublease, or termination of such term in any other way, the sublessee shall be under obligation to evacuate and hand over the leased property in its former state, and the sublessee shall be held liable for any wear or damage that is beyond what is caused by normal use. The sublessee shall pay an amount in EURO equal to 1/15 of the monthly sublease fee paid at that time as penalty for every day of delayed delivery of the leased property, and such penalty is hereby agreed upon and recognized as fair and reasonable.

9. The sublessee shall bear the costs incurred for the water and electricity consumed in the leased property, waste collection fees, municipal fees in general, as included in the Public Power Corporation (PPC) bills, the entire stamp duty fee that corresponds to the sublease fee, as well as the sewage fees and other costs charged to the leased property for the jointly used and jointly owned areas of the Building Complex, in accordance with horizontal property establishment deed no. 6.086/97 drafted by Athens Notary Public Paraskevi Theodorakou, as amended, whereas it is hereby agreed upon that this sublease agreement is subject to the rights, obligations and limitations arising therefrom, and the sublessee hereby states that it has become fully aware thereof through its above representatives.

10. Any breach or violation of any of the conditions set forth herein, which are all agreed upon to be material ones, and in particular a failure to pay the sublease agreement and the corresponding stamp duty fee within the set deadline and without any reminder, shall enable the sublessor to terminate this sublease agreement unilaterally and request the sublessee to hand over the leased property in accordance with applicable provisions, as well as to make good of any damage resulting therefrom.

11. Should the parties fail to exercise their rights arising herefrom immediately and strictly, this shall under no circumstances be interpreted as a silent amendment to the terms and conditions hereof, as it is hereby expressly agreed upon that any amendment to the terms and conditions hereof shall be agreed upon and proved only in writing.

12. The sublessee shall be under obligation, within five (5) days of signature hereof, to pay to the sublessor an amount equal to three monthly sublease fees, namely Euro seventy seven thousand eight hundred and seventeen and sixty nine cents (€ 77,817.69), which shall remain in the hands of the sublessor free of interest throughout the term of this sublease agreement as guarantee of the appropriate performance on the part of the sublessee of the terms and conditions hereof, of the Regulation of the Building Complex, as well as of the obligations applicable to lessees as arising from the law. Said guarantee, which may not be offset against any claim, not even against the last sublease fees, shall be increased by the sublessee in the first month of each one of the following years of lease so that it is equal to three (3) sublease fees, and it shall be refunded to the sublessee after lapse of thirty (30) days of the expiry date of the term of the sublease providing that the latter has handed over the use of the leased property within the set deadline and has handed over to the sublessor receipts of payment of all bills relating to the leased property, and on

condition that there is no reason for a forfeiture of the guarantee in favor of the sublessor.

13. This sublease agreement is one single agreement, and thus it cannot be terminated by the sublessee only for part of the leased property; it can be terminated only for the entire leased property.

14. Any dispute arising herefrom shall be settled by the Courts of Athens, and the agreement shall be governed by the Law of Greece.

In witness whereof, this agreement was drafted in five (5) identical originals, which after being read and confirmed, were signed by the above representatives of the contracting companies, and each one of them received one (1) original, whereas the rest of them shall be submitted to the competent Tax Offices (DOY).
