	 	(i)	the matter in relation to which the Deadlock arose shall not be discussed by the relevant Shareholders’ Meeting or Board of Directors’ meeting and the Parties shall
reconvene in a new Party’s Prior Meeting within five (5) days from the date in which the Deadlock arose to discuss and resolve the Deadlock and shall promptly call the new relevant Shareholders’ Meeting or Board of Directors’ meeting;

  

 10 

	 	(ii)	in case of failure by such new Parties’ Prior Meeting to solve the Deadlock, the respective Chairman of the Parties shall meet to resolve it within ten (10) days from the date

arbitration conducted in accordance with the Rules set forth by the ICC, Paris. Each of LOS W, on the one hand, and TII, on the other hand, shall have ten (10) days to select its arbitrator after receipt of a notice by the Party requesting
arbitration in accordance with the foregoing. If any Party does not make such appointment within such time, the ICC Rules shall apply for the appointment of such arbitrator. Upon such selection, the two party-appointed arbitrators shall have ten
(10) days to appoint the chairman and, if the two party-appointed arbitrators do not make such appointment within such time, the President of ICC shall make such appointment within ten (10) days. The chairman shall be a businessman or a lawyer with

 12 

	7.3	Notwithstanding anything to the contrary in this Agreement, no direct or indirect transfer of any Shares, including transfer to Affiliates, shall be permitted (i) unless, prior to
such transfer, the transferee executes and delivers a counterpart copy of this Agreement or otherwise agrees to be bound by the terms and conditions hereof to the transferring Party in form and substance reasonably satisfactory to the other Party;
(ii) unless such transfer would not result in a breach of any provision of this Agreement applicable to the transferring Party and (iii) all Authorizations required for such transfer, if any, have been obtained. 

  

	7.4	Notwithstanding anything to the contrary in this Agreement, LOS W and TII shall be entitled, upon prior written notice to the other Party, to transfer all, but not less than all, of
its Shares to any of its Affiliate; except that Los W is entitled to partially assign its shares for two times only to two of its affiliates, provided that prior to such transfer, the Affiliate agrees in writing with each LOS W and TII to
transfer such Shares back to the transferring Party (and the transferring Party shall buy back such Shares) immediately in the event that such Affiliate ceases to be an Affiliate of the transferring Party, and Section 7.3 and all other applicable

	7.5	The Parties may directly or indirectly transfer or accept an offer to transfer all or part of the Shares to any person, provided that: 

  

	 	(i)	 In case a Party (the “Selling Party”) intends to transfer its Shares and shall have received a bona fide offer (solicited or unsolicited) in
writing (a “Bona Fide Offer”) from any third party (the “Third Party”), which Bona Fide Offer shall provide for the purchase of all (but not part) of the Selling Party’s Shares (the “Transfer
Shares”) in exchange for the consideration specified therein, the Selling Party shall first give written notice (the “Transfer Notice”) to the other Party (the “Non-Selling Party”) stating (1) the Selling
Party’s intention to transfer the Transfer Shares pursuant to the Bona Fide Offer, (2) the number of Transfer Shares, (3) the name and address of the Third Party, (4) the offered purchase price per share of the Transfer Shares, expressed solely
as a Dollar amount, and the manner of payment thereof (which shall be solely in the form of cash or other form of payment in immediately available funds) and (5) such other information regarding the Bona Fide Offer and the Third Party as the
Non-Selling Party may reasonably request. The Transfer Notice shall be 

  

 13 

	 	 
accompanied by a copy of the Bona Fide Offer, which shall be in writing and signed by the Third Party and by a guaranty or letter of credit of the Selling
Party in form and substance reasonably satisfactory to the Non-Selling Party for an amount equal to ten percent (10%) of the aggregate proposed purchase price (“Closing Guaranty”), which Closing Guaranty may be drawn upon by the
Non-Selling Party in the event the sale of the Transfer Shares is not consummated in accordance with the terms of this Section 7; 

  

	 	(ii)	The Non-Selling Party shall have the irrevocable right, but not the obligation, to purchase the Transfer Shares. Such option (the “Right of First Refusal”) shall be
exercised by notifying the Selling Party within sixty (60) days from receipt of the Transfer Notice. Failure by the Non-Selling Party to deliver the notice hereunder shall be deemed an election not to exercise the Right of First Refusal;

  

	 	(iii)	In the event that the Non-Selling Party elects to exercise the Right of First Refusal, the Selling Party shall effect the proposed transfer with respect to the Transfer Shares on
the terms (as regards price and method of payment) set forth in the Transfer Notice and the transfer of Transfer Shares shall take place on or before the 120th day following receipt of the Transfer Notice (the “Shareholders Closing”), when the Selling Party shall deliver to the Non-Selling Party the certificate or certificates representing
the Transfer Shares, and, in addition, the Share transfer form, against delivery by the Non-Selling Party of the purchase price thereof as specified in the Transfer Notice. 

  

	 	(iv)	In case LOS W is the Non-Selling Party, it shall also have the irrevocable and exclusive option, but not the obligation, to sell to the Third Party, the same number of shares that
the Selling Party intends to transfer to the Third Party up to the number of shares owned by LOS W (the “Tag Along Right”), in which case the Selling Party shall ensure that, if the Third Party acquires the Transfer Shares, the
Non-Selling Party Shares are sold at a price per share equal to the price per share and on the same terms and conditions indicated in the Transfer Notice. The Tag Along Right shall be exercised by notifying the Selling Party within sixty (60) days
of receipt of the Transfer Notice by the Non-Selling Party. Failure by the Non-Selling Party to deliver the notice hereunder shall be deemed an election not to exercise the Tag Along Right. 

  

 14 

	 	(v)	In the event that the Non-Selling Party elects to exercise the Tag Along Right, the Selling Party may accept the Bona Fide Offer, giving copy of such accepting to the Non-Selling
Party. 

  

	 	(vi)	In the event that the Non-Selling Party does not exercise the Right of First Refusal or the Tag Along Right, or if the Non-Selling Party exercises such a Right of First Refusal or
Tag Along Right but the sale of the Transfer Share is not consummated as provided herein based on actions or inactions of the Non-Selling Party (the date of the occurrence of either of such events being the “Non-Selling Party Termination
Date”), then the Selling Party shall be free to sell to the Third Party all the Transfer Shares (in whole and not a part thereof) on the terms set forth in the Bona Fide Offer; provided, however, that all other restrictions on such Transfer
set forth in this Agreement have been satisfied. If such sale to the Third Party is not consummated or the related share purchase agreement is not entered into within sixty (60) days from the Non-Selling Party Termination Date, the Transfer Shares
shall once again become subject to the restrictions of this Section 7. 

  

	7.6	Notwithstanding anything to the contrary contained herein, in the event that TII receives a Bona Fide Offer to acquire the entire Company share capital, then TII shall have the
right to require to LOS W, or any successor thereof, and LOS W, or any successor thereof, shall be obliged to, sell to the Third Party all its shares at the same terms and conditions set forth in the Bona Fide Offer, provided however that the price
per share shall be not lower than a price as it results from a value for the one hundred per cent of the Company share capital equal to the fair market value as defined in Appendix A, hereto and 331,833,000 USD whichever is higher.

  

	7.7	LOS W Controlling Shareholder shall be entitled to, upon prior notice to the Company and to TII, to transfer their respective shares in LOS W between or among themselves (and only
in this case) without being subject to the obligations and restrictions set forth in Section 7 herein, provided however that no transfer to a third party will be valid without the prior approval of TII.

 ARTICLE 10. EVENT OF DEFAULT 
  

	10.1	Failure to comply with the provisions set forth in Sections 3, 4.1, 7, 9 and 13, due to action or omission of any Party shall constitute an event of default of such non complying
Party (“Event of Default”). In the event that LOS W, on the one hand, or TII, on the other hand, commit an Event of Default, LOS W (in case of an Event of Default of TII) or TII (in case of an Event of Default of LOS W)
(respectively, as the case may be, the “Non-Defaulting Shareholder”) shall have an irrevocable right, but not the obligation, to (i) buy from the other Party (“Share Purchase Option”) or (ii) sell to the other Party
(“Share Sale Option”) in accordance with the terms set forth below, all and not less than all of the Shares then owned (whether directly or indirectly) by LOS W or TII, as the case may be. 

  

	10.2	The Share Purchase Option or the Share Sale Option may only be exercised after the occurrence of any of the Event of Default and notice of such exercise must be delivered in writing
by the Non-Defaulting Shareholder to the other Party, provided however that the Non-Defaulting Shareholder shall grant a cure period of fifteen (15) days from the date in which such notice has been sent (“Cure Period”), and provided
that failure of the Non-Defaulting Shareholder to exercise its rights under this Section with respect to any Event of Default shall not constitute a waiver of such rights with respect to any subsequent Event of Default. 

  

 16 

	10.3	The price of the Share Purchase Option (hereinafter, the “Purchase Price”) shall be equal to the Fair Market Value of the Shares sold (as defined in Section 10.9
below) minus ten percent (10%), and the price of the Share Sale Option (hereinafter the “Sale Price”) shall be equal to Fair Market Value of the Shares sold plus ten percent (10%). 

  

	10.4	In the event a Non-Defaulting Shareholder is exercising rights under the Share Purchase Option and the Event of Default has not been cured within the Cure Period by the Party which
is not the Non-Defaulting Shareholder, the Non-Defaulting Shareholder must pay the Purchase Price of the Shares being purchased to the Party, whichever is not the Non-Defaulting Shareholder (such Shareholder, the
“Shareholder-at-Fault”) within thirty (30) days after final determination of the Fair Market Value of the Shares. In the event a Non-Defaulting Shareholder is exercising rights under the Share Sale Option, the Shareholder-at-Fault
must pay the Sale Price for the Shares of LOS W (in the case that LOS W is the Non-Defaulting Shareholder) or the Shares of TII (in the case that TII is the Non-Defaulting Shareholder) within thirty (30) days after determination of the Fair Market
Value of the Shares. In both cases, all amounts shall be indexed for inflation as determined, as from the date the Fair Market Value of the Shares of the Company is determined, in accordance with the applicable index to be mutually agreed between
LOS W and TII, and in the absence of agreement between said Parties, that index determined by the Non-Defaulting Shareholder auditors. In the event selling Shareholder happens to be TII, the Sale Price shall be remitted abroad as indicated by TII
and paid to TII in U.S. Dollars. Upon payment of the Purchase Price or Sale Price, as applicable, the Non-Defaulting Shareholder, and other appropriate Shareholders, shall execute the applicable corporate books and registries of the Company and any
other corporate documents or instruments reflecting the assignment and transfer of the applicable Shares to the Non-Defaulting Shareholder in accordance herewith, or the assignment and transfer of all of the Non-Defaulting Shareholder’s Shares
to the applicable Shareholder in accordance herewith. 

  

	10.5	Each Party shall pay and shall be subject to all taxes imposed on it by applicable laws and regulations on the sale, assignment and transfer of the Company’s Shares described
in this Section 10. 

  

	10.6	In the event an assignment and transfer of Shares takes place under the provisions of this Section 10, this Agreement shall be terminated in relation to the selling Shareholder and
shall produce no further effects thereafter, except that such termination shall in no way operate to impair, exclude or destroy any other rights or remedies of any Party (including selling Shareholder or any individuals or companies in any way
related, whether directly or indirectly, to same) under this Agreement, nor shall it 

  

 17 

 relieve any Party (including selling Shareholder or any individuals or companies in any way related,
whether directly or indirectly, to the same), or Company of its obligations to comply with any of the provisions of this Agreement, which obligations have accrued prior to the effective date of termination or which are expressly stated to survive
termination or which, by their very nature, are intended to survive termination. 
  

	10.7	The Parties and their respective successors under whatever title shall not invoke any provision of this Agreement or of any other agreement or instrument, to hinder, thwart or in
any way prevent the sale, assignment and transfer of Shares provided for in this Section or any other Section from being fully carried out and the sale, assignment and transfer of shares being duly formalized. Moreover, the selling Shareholders
shall deliver to the purchasing Shareholders good title, free and clear of any liens, claims, charges, encumbrances, security interests or options of whatever kind, to its shares and shall transfer all rights inherent to them such as voting rights,
profits, dividends, bonuses and preferences. Selling Shareholders and their respective successors shall be liable for all and any obligations or liabilities inherent or related to the Shares prior to their final sale, assignment and transfer to
purchasing Shareholders. 

  

	10.8	In case the Non-Defaulting Shareholder exercises the Share Purchase Option or the Share Sale Option, as the case may be, the provisions of this Section shall expressly survive the
termination of this Agreement until the transactions contemplated herein are fully completed. 

  

	10.9	 For the purpose of this Section, “Fair Market Value” of the Shares sold shall mean, at any time, the fair market value per Share, as of the last
day of the month prior to the date notice of a Share Purchase Option or Share Sale Option is exercised hereunder multiplied by the number of Shares held by the selling Shareholder, increased by the amount of any distributions to which the selling
Shareholder is then entitled but which have not yet been paid and otherwise determined as follows: (i) a value of the Company as a going concern determined in good faith by LOS W and TII based upon both short term and long term considerations that
are customary in such valuations, including, but not limited to, the most recent financial statements, with consideration for any non-recurring events that would not normally affect the value of a company, public market values (or known recent
private transaction valuations) of comparable companies and/or companies in similar industries, and structural and/or strategic changes to Company and its subsidiaries, but without any control premium or minority discount, and a value of the Company
based on internationally common methods of appraisals, such as, inter alia, discounted cash flow analysis (taking into account the most recent approved business plan of the Company); and (ii) if LOS W and TII cannot agree upon the Fair Market Value
of the Shares to be sold pursuant to clause (i) above within ten (10) days after the date notice of the exercise of 

  

 18 

	 	 
a Share Purchase Option or Share Sale Option is received, the value as determined by an appraisal which shall value the Company as a going concern based upon
the considerations set forth in clause (i) above. Such appraisal shall be conducted (A) by a firm of internationally recognized investment bankers jointly selected by LOS W and TII or (B) if such Shareholders are unable to agree on a single firm of
investment bankers, by two internationally recognized investment banking firms, each selected by LOS W and TII, each of which shall determine the Fair Market Value, in which case the Fair Market Value of the Shares of the firms shall separately
determine, within 45 days of the end of the above-mentioned 10 days selling Shareholder shall be the average of the two valuations. Each of the investment banking period, the Fair Market Value of the Shares. Each investment banking firm shall
express its valuation as a single number in US dollars. The mid-point of the valuation (the “Mid-Point”) will then be calculated by dividing the sum of the two separate valuations by two. To the extent that such valuation is within
the range which is 10% above or 10% below the Mid-Point (the “Range”), the Mid-Point shall be used. If either or both the valuations fall outside of the Range, then LOS W and TII shall jointly choose (or, if LOS W and TII are unable
or unwilling to so jointly choose, the two appraisers shall choose) a disinterested internationally recognized investment banking firm as a third appraiser to complete an appraisal within an additional 45 days, which appraisal shall be equal or
somewhere between the two prior appraisals and such third appraisal shall be the final and binding determination of the Fair Market Value. 

  
         In addition, for purposes of determining Fair Market Value hereunder, all transactions between any Company
and/or its subsidiaries, employees, directors or shareholders shall be calculated on the basis of an arms length transaction. The determination of the Fair Market Value as determined pursuant to this Section 10.9 shall be final and conclusive on all
Parties hereto, absent manifest error. The cost of determining the Fair Market Value shall be borne by the Shareholder-at-Fault.
