VI. INDEMNIFICATION

6.1.Seller and NET hereby agree to indemnify and hold the other Party and its shareholders, officers, directors and employees harmless from any and all liability and/or damage (including reasonable fees and expenses of attorneys)
(Losses)incurred solely from any breach or exclusively as a result of any liability which may be charged against each other resulting from any breach of the representations and warranties of Article V hereof (each of the
liabilities, claims and proceedings mentioned above, if any, shall be hereinafter referred to as "Contingency"or "Contingencies").

6.1.1.NET recognizes that the Transaction contemplated in this Agreement is an "as is" transaction, and that, except for the Contingencies, no amounts whatsoever related to any liabilities of Vivax will be indemnified by Seller to NET, other
than in case of proven willful misconduct of Seller, as declared in a final decision not subject to further appeal.

6.1.2.Seller shall be liable for the representations and warranties provided in Sections 5.1.1, 5.1.2, 5.1.3, 5.1.4, 5.1.5, 5.1.6, 5.1.7, 5.1.8 and 5.1.9. NET shall be liable for the representations and warranties provided in Sections 5.2.1,
5.2.2, 5.2.3, 5.2.4, 5.2.5, 5.2.6, 5.2.7, 5.2.8, 5.3.1, 5.3.2, 5.3.3, 5.3.4 and 5.3.5.

6.2.Each of the Seller's or NET's obligations to indemnify each other for Losses and/or Contingencies arising herefrom shall remain in force as follows:

(i) the obligations related to Sections 5.1.1, 5.1.2, 5.1.3, 5.1.4, 5.1.5, 5.2.1, 5.2.2, 5.2.3, 5.2.4, 5.2.5, 5.3.1, 5.3.2, 5.3.3, 5.3.4 and 5.3.5 shall remain in force for the period provided in the applicable statute
of limitations.

(ii) all others shall remain in force for a term of 3 (three) years as from the Closing Date ("Guaranteed Periods").

---

##### 

6.3.In the event, during the Guaranteed Periods, a material Contingency arises which is ascribable to the Seller, pursuant to Section 6.1 above, NET shall notify the Seller in writing, which notice shall mandatorily contain the details of
the Contingency ascribed thereto, and said notice shall be presented no later than the last day of one half of the period available for the presentation of the relevant defense or counterclaim. If NET does not present the above mentioned notice
within the prescribed period, it shall be solely liable for the defense or counterclaim in relation to the Contingency, as well as for the respective outcome thereof, including, but not limited to the costs and attorney and court fees, incurred as a
result therefrom. Notwithstanding the foregoing, the Seller shall, at all times and for so long as the defense proceedings may last, keep NET abreast of the developments of such defense, providing NET, at their request, with any and all information
and writings filed by the Seller with the relevant court.

6.3.1.Subject to the terms of Section 6.3 above, the Seller may either decide to present a defense or counterclaim or pay the amount required under the Contingency, and the Seller shall be liable for the payment of or defense against such
Contingency and shall provide all necessary funds to timely cover any and all costs incurred, including guaranties and reasonable attorney and court fees, in relation to the Contingency. If the Seller does not so acknowledge its obligation to
indemnify and does not assume the defense of any such Contingency within the above prescribed period, NET may, but it is not obliged to, defend against such litigation using counsel of its choice, in such manner as it may reasonably deem
appropriate, including, but not limited to, settling such claim at its own and exclusive discretion.

6.3.2.In case the Seller assumes the defense or counterclaim, NET shall wait until a final decision, not appealable, is given. If, after such final decision is given, the result is totally favorable to NET and/or Vivax, as the case may be,
no indemnification shall be due; if the decision is partially favorable, or completely adverse to NET and/or Vivax, as the case may be, the Losses to be established as effectively suffered by NET and/or Vivax in connection with the total amount of
the adverse judgment, excluding the judicial costs and other expenses directly incurred by the Seller, shall be indemnified by the Seller to NET and/or Vivax, within a term of up to 10 (ten) Business Days.

6.3.2.1.In the case either Seller or NET fails to reimburse each other for the Losses with the time set forth above, the obligation of either the Seller or NET shall be indexed in accordance with the variation of the IGPM until the date
payment of the Losses is effectively made.

6.3.3.In case the Seller opts to present the defense or counterclaim, as prescribed in Section 6.3.1 above, the Seller shall be entitled to appoint counsel of its trust, of undisputed reputation, to defend the interests of NET and/or Vivax,
as the case may be, provided that such counsel shall be reasonably satisfactory to NET and/or Vivax and that the Seller shall bear any and all relevant attorneys' fees and all other related costs and expenses. If NET in good faith determines that
the claim is not appropriately conducted by the counsel indicated by the Seller, it may request that such counsel is replaced by another attorney reasonably satisfactory to both Seller and NET. In this case, NET/Vivax shall grant sufficient powers
to the counsel indicated by the Seller. NET and Vivax further agree to facilitate the development of the work, by supplying or providing for the supply, to the professionals chosen by the Seller, of all the data and information available necessary
for the defense of the claim or counterclaim, being the expenses deriving therefrom of the responsibility of the Seller.

---

##### 




6.4.In the event that, during the Guaranteed Periods, a Contingency arises which is ascribable to NET, pursuant to Section 6.1 above, Seller shall observe the same proceeding set forth in Section 6.3 above, as it may be applicable.

execution of this Agreement. Provided that NET is able to reduce the period between the date hereof until the Closing Date to 50 (fifty) days and sends the notification mentioned in Section 4.1 above, HUT will reduce the 55 (fifty) days term set
forth herein to 45 (forty five) days.
