Purchaser, Roberto, Lorena, Mobitec AB, JADI and the Company hereinafter referred to individually as “Party” and jointly as “Parties”;

WHEREAS:

(a)		on July 22, 2009, the Parties entered into a Quota Purchase Agreement (the “QPA”) pursuant to which Roberto and Lorena agreed to sell, assign and transfer the totality of Quotas they held in the Company to the Purchaser and the Purchaser agreed to purchase such Quotas from the Sellers, according and subject to the terms and conditions contained therein;
(b)		due to certain legal requirements, Roberto and Lorena needed to amend the JADI Reorganization in order to exclude Lorena’s direct equity participation in the Company leaving Roberto as the lawful and sole owner of 1,944,825 quotas, representing 50% (fifty percent) of the Company’s corporate capital, total number of quotas which were assigned to the Purchaser under the terms of the QPA;
(c)		as a result of such amendment to the JADI Reorganization, the parties will need to amend (i) the terms of the QPA in order to reflect that Lorena is no longer a Seller, but an intervening party and guarantor of the obligations of the Seller; (ii) the corporate documents of JADI to reflect the changes to the JADI Reorganization; and (iii) the corporate documents of the Company to reflect the changes to the JADI Reorganization and to the terms of the QPA (4th and 5th Amendments to the Articles of Association, respectively);

NOW, THEREFORE, in consideration of the foregoing premises and of the mutual covenants and agreements set forth, each of the Parties hereby covenant and agree to execute this Amendment to the Quota Purchase Agreement (“Amendment”) as follows:

meaning ascribed to such terms in the QPA.

2 Amendments to the QPA

2.1 Due to legal requirements imposed by Governmental Authorities, Roberto and Lorena needed to amend the JADI Reorganization so that only Roberto would have a direct equity stake in the Company as of the date of the JADI Reorganization, which is prior to the execution of the QPA.

2.1.1 As a result of the changes to the JADI Reorganization, (i) Lorena no longer holds a direct equity participation in the Company and therefore can no longer be considered as a Seller of the Quotas under the terms of the QPA; and (ii) Roberto will hold all the Quotas, as defined in the QPA, corresponding to 50% of corporate capital of the Company, and therefore be considered as the sole Seller of the Quotas.

2.1.2 The Parties agree and acknowledge that the effects of the changes of the JADI Reorganization retroact to the date of the JADI Reorganization and therefore all the changes being implemented under this Amendment will also retroact to the date of the QPA, unless if otherwise specified. Any references to the JADI Reorganization shall be understood as the amended JADI Reorganization.

2.2 In view of the changes mentioned above, the QPA and its schedules are hereby amended as follows:

(a) The reference to Lorena in the preamble of the QPA as “Seller” shall be deleted and “Lorena” shall be inserted in lieu thereof, and Lorena shall be considered, together with JADI, as “Intervening Party and Guarantor” of the Seller obligations, being bound by all the terms and conditions thereof applicable to such condition;

(b) All instances in the QPA of “Sellers” or “each of the Sellers” or “each Seller” shall be deleted and “Seller” shall be inserted in lieu thereof, with the necessary grammatical adjustments, such that only Roberto will be considered as Seller;

(c) All instances in the QPA of Lorena, in her capacity of a Seller shall be deleted and “Roberto” shall be inserted in lieu thereof, such that only Roberto will be considered as Seller;

(d) All instances in the QPA of Seller shall mean Roberto;

(e) All the remaining instances in the QPA that refers to “Lorena”, other than those referred in item “c” above, shall be understood such a manner that Lorena is considered as an Intervening Party and Guarantor of the Seller’s obligations, jointly and severally with JADI;

(f) The chart contained in Section 2.1 of the QPA shall be deleted in its entirety and the following chart is inserted in lieu thereof:

Quotaholder		Number of Quotas to be sold				Percentage of total
Roberto Demore			1,944,825				100

(h) The Parties hereby agree to replace the first and second promissory notes as provided in Sections 2.5 and 2.6 of the QPA, respectively, in order to exclude Lorena as beneficiary of the notes. The remaining terms and conditions shall not change. In this respect, upon delivery of the original notes by Roberto and Lorena, concurrently with the execution of this Amendment, the Purchaser shall deliver new promissory notes to substitute such notes;

(i) The Parties undertake to sign concurrent with this Amendment new versions of the following closing deliveries provided for in Section 2.7 of the QPA in order to reflect that Roberto is the sole holder of the Quotas: (i) Statement of Absence of Debt (Section 2.7 (a)); (ii) Power of attorney to be granted by the Seller to the Purchaser (Section 2.7 (b)); (iii) 5^th Amendment to the Articles of Association of the Company to consummate the transfer of the Quotas (Section 2.7 (c)); (iv) Power of Attorney to be granted by the Purchaser to the Seller as per Section 2.10 (Section 2.7 (l);

(j) Section 12.15 shall be amended to include Lorena as an intervening party and guarantor of the obligations of the Seller. Therefore, Section 12.15 shall read as follows:

“12.15 Intervening Parties. JADI and Lorena sign this Agreement in the capacity of guarantors of the Seller being jointly and severally responsible for any and all obligations assumed by the Seller under this Agreement and any other agreement mentioned herein, including, without, limitation, the obligation of the transfer of the Quotas and the fulfillment of any and all of the acts necessary to be done or executed by the Seller in order to complete the transfer of the Quotas, renouncing any and all benefits that JADI may have specially the benefits of order, division and enforceability established under Brazilian Law.”

2.3 The Parties further undertake to sign a new 4^th Amendment to the Articles of Association of the Company to reflect the changes to the JADI Reorganization.

3.3 The Parties hereby ratify all other provisions of the QPA that have not been expressly amended pursuant to this Amendment.

3.4 This Amendment shall be construed and governed by the laws of the Federative Republic of Brazil.

3.5 Any dispute, controversy or claim arising out of, relating to, or in connection with, this Amendment, or the breach, termination or validity thereof, shall be finally settled by arbitration pursuant to the provisions set forth in Article 13 of the QPA. For this purpose, all references to “QPA” contained therein shall read as references to “Amendment”.

3.6 This Amendment is executed on this date in both the English and Portuguese languages. In case of conflict between both versions, the Portuguese version shall prevail.

IN WITNESS THEREOF, the Parties execute this Amendment in 2 (two) counterparts of equal form and value, for one purpose and in the presence of the 2 (two) witnesses signed below.
