Agreement. Therefore from Closing Date, the Parent Companies will be liable individually and severally (“mancomunadamente”)
between both –(74.5% in the case of Inversiones Frieira, S.L. and 25.5% in the case of Vetra Energy Group LLC) of the potential
payment obligations, including all the Seller’s obligations to indemnify any Losses suffered by the Purchaser as a result
of any breach of the Sellers’ Warranties set forth in Article 6 (the “Assignment of Obligations”).

 

		22.2	Likewise, the Seller,
by mean of this Agreement assigns to Parent Companies, individually and severally (“mancomunadamente”) in the proportion
of their stake in the share capital of Seller all the rights hereunder (the “Assignment of Rights”).

 

		22.3	As a result of the Assignment
of Obligations, the Purchaser expressly agree to release the Seller from any such payment obligations under this Agreement and
under the Liability Acknowledgement Agreement. As previously set forth, each of the Parent Companies shall be liable vis-à-vis
the Purchaser individually and severally (“mancomunadamente”), in the proportion 74.5%/25.5% of any and all
payment obligations arising from the Seller’s obligations under this Agreement and under the Liability Acknowledgement Agreement.

 

    	 	37	 

     

    

 

		22.4	The Purchaser expressly
accepts the terms and conditions of the Assignment of Obligations and the Assignment of Rights and, therefore, acknowledges that
on the Closing Date, once the Assignment of Obligations and the Assignment of Rights are effective, Seller will be automatically
released against the Purchaser from any and all Losses. The Purchaser irrevocably waives any and all judicial or extra-judicial
claims to be brought after the Closing Date against the Seller related to this Agreement and under the Liability Acknowledgement
Agreement.

If and for so long
as any provision of this Agreement shall be deemed to be judged invalid for any reason whatsoever, such invalidity shall not affect
the validity or operation of any other provision of this Agreement except only so far as shall be necessary to give effect to the
construction of such invalidity, and any such invalid provision shall be deemed severed from this Agreement without affecting the
validity of the balance of this Agreement.

 

For the avoidance of
doubt, if and for so long as any provision of this Agreement shall be deemed to be judged invalid for any reason whatsoever, Purchaser
and Seller shall negotiate in good faith, and use reasonable endeavors, to agree an alternative valid provision which, as far as
possible, reflects the commercial terms and/or effect of the provision judged invalid.
