HG Supplementary Agreement

This SUPPLEMENTARY AGREEMENT (the “Supplementary Agreement”) is made and entered into as of June 3, 2021, between IG4 Capital Infrastructure Investments LP, an investment fund organized under the laws of Scotland (the “Offeror”), and Xxxxxxxx Xxxxxxxxx Xxxxxxxxxx Xxxxx Xxxxx (“Xx. Xxxxx Xxxxx”), in witness of Xxxxxxx Xxxx Xxxxxx (“Xxx. Xxxx Xxxxxx”).

Reference is made to (i) the Tender Offer Support Agreement dated August 24, 2020 (as amended, supplemented, or otherwise modified) (the “TOSA”) entered into by and among the Offeror and the Shareholders listed in Annex A of the TOSA (together, the “Sellers”), which includes Xx. Xxxxx Xxxxx; and the Trust Agreement (Contrato de Fideicomiso en Garantía) dated June 3, 2021, entered into by and among the abovementioned parties (the “Trust Agreement”). Capitalized terms not otherwise defined herein shall have the meaning given to such terms in the TOSA or the Trust Agreement, as applicable.

By means of this Supplementary Agreement, and in connection with the TOSA, the Offeror and Xx. Xxxxx Xxxxx have agreed the conditions for a post-Settlement Date transfer of 15’531,208 Outstanding G&MSAA Shares, legally and beneficially owned by Xx. Xxxxx Xxxxx (the “HG Shares”) to the Offeror in the form detailed in this Supplementary Agreement.

The Parties hereby agree that pursuant to Section 6.3(c) of the TOSA, this HG Supplementary Agreement shall be automatically and immediately terminated if the Offeror has not been able to secure a “participación significativa” in the OPA.

In connection thereto, this Supplementary Agreement shall be subject to the following terms and conditions:

1. Representations

(i) Xx. Xxxxx Xxxxx and his spouse, Xxx. Xxxx Xxxxxx, entered into a division of joint property on May 24, 2018 and its registered in the entry N° 14322724 of the Public Registry of Individuals. However, as of the date hereof, Xx. Xxxxx Xxxxx is the registered owner of the HG Shares, holding good and valid title of the HG Shares, except for the seizure (embargo e inhibición) of 9’720,222 HG Shares and the seizure (incautación) of 5’810,986 HG Shares, recorded by the Peruvian Public Prosecutor (Fiscalía) and the Attorney General (Procuraduria) (the “HG Shares Encumbrance”).

Notwithstanding the above, the Shareholders hereby represent that they have submitted a request to the courts to release the Tori Shares (as defined in Section 5 below) and, upon such release, the HG Shares shall be equivalent to 7’765,604 shares, which shall remain seized as detailed in the above paragraph. For the

avoidance of doubt, on the execution date of this HG Supplementary Agreement, there is no order to seize, lien or encumber the Tori Shares.

(ii) Except as set forth in Annex J of the TOSA, there is no Action pending or, to the Knowledge of Xx. Xxxxx Xxxxx, threatened by or against him, in such capacity, which challenges or seeks to prevent, enjoin or otherwise delay the transactions contemplated by the Transaction Documents.

(iii) Except for the seizure detailed in Section 1(i) above, Xx. Xxxxx Xxxxx is not, and none of its assets or properties are, subject to any Governmental Order (nor to the Knowledge of Xx. Xxxxx Xxxxx, are there any such Governmental Orders threatened to be imposed by any Governmental Entity), which could affect the legality, validity or enforceability of the Transaction Documents or the consummation of the transactions contemplated in the TOSA.

(iv) Xx. Xxxxx Xxxxx hereby reaffirms and ratifies all other representations and warranties set forth in Article III of the TOSA.

2. Syndication Agreement

(i) On the execution date of the Trust Agreement, Xx. Xxxxx Xxxxx and the Offeror, with the intervention of Xxx. Xxxx Xxxxxx, shall execute a share syndication agreement regarding the HG Shares (including the Tori Shares) (the “Syndication Agreement”), in the form attached as Annex A of this Supplementary Agreement.

(ii) The terms and conditions set forth in the TOSA and in the Trust Agreement shall be as applicable to the Syndication Agreement, accordingly.

(iii) The term of the Syndication Agreement shall be either (i) the same terms as the Trust Agreement; or (ii) upon release and cancellation of the HG Shares, whichever occurs first.

3. HG Shares Encumbrance

(i) Upon cancellation of the HG Shares Encumbrance and provided that the Trust Agreement is still in force, Xx. Xxxxx Xxxxx (and Xxx. Xxxx Xxxxxx) shall, in no later than three (3) LSE Business Days after such cancellation and its registration in Cavali, transfer 7’765,604 HG Shares and any new shares issued to Xx. Xxxxx Xxxxx as stated in Section 3(ii) below (the “HG Trust Shares”) to the Trust, under the terms and conditions set forth in the TOSA and the Trust Agreement, and the Offeror will pay to Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx the Political Rights Consideration pursuant to Sections 2.2(b)(iii) and 2.3(b) of the TOSA.

Upon confirmation of transfer of HG Trust Shares to the Trust by the Trust Agent, (x) such transfer will be deemed completed and the Trust Agent shall complete and update the Trustors’ Registry pursuant the Trust Agreement; (y) the Trust will be the holder of record of the HG Trust Shares –along with the other Trust Shares–; and, (z) as provided and under the terms and conditions set

forth in the Trust Agreement, the TOSA and this Supplementary Agreement, Xx. Xxxxx Xxxxx –together with the Sellers that transferred Shares to the Trust– will have the right to exercise the Economic Rights of their corresponding Trust Shares (including the HG Trust Shares) and other payments pursuant to Section 6.5 of the Trust Agreement; and the Offeror shall have the right to exercise the Political Rights of the HG Trust Shares (together with the other Trust Shares) including the Drag Along Right and the Tag Along Right, and to receive the performance fee (Honorarios de Desempeño) pursuant to Section 6.5 of the Trust Agreement.

(ii) If a capital increase in the Company is resolved and new Shares are allotted to the Shareholders of the Company –as provided in the Company’s Bylaws and the Law– then (x) if the Shares entitled to Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx are not encumbered, lien, charged or under any other burden, then such allotted Shares shall be transferred to the Trust in accordance with the terms of Section 5.3 of the Trust Agreement; or (y) if such Shares allotted to Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx are under the HG Shares Encumbrance, then the Syndication Agreement shall include and govern such new Shares.

(iii) In case the Offeror is interested in transferring its Shares to the Purchaser, by triggering the Drag Along Right established in Section 6.8 of the Trust Agreement, and provided that the cancellation of the HG Shares Encumbrance has not yet occurred, then the Offeror may assign (cesión de posición contractual) to the Purchaser the Syndication Agreement (and Xx. Xxxxx Xxxxx xxxxx consents to such assignment) and the Purchaser will be obliged to acquire the entire HG Shares –at the time of the cancellation of the HG Shares Encumbrance– pursuant to the terms of this Supplementary Agreement.

4. Offer

(i) The Offer procedure for 7’765,604 HG Shares (the “HG Ownership Procedure”) shall occur upon the cancellation and release of the HG Shares Encumbrance, in accordance with the Applicable Law and the terms and conditions set forth in this Section 4 of the Supplementary Agreement.

(ii) The HG Ownership Procedure shall be conditional upon the following matters continuing to be true and accurate at the time of the HG Ownership Procedure:

(a) all representations and warranties in Section III of the TOSA remain true and accurate.

(b) all formal procedures to release and cancel the HG Shares Encumbrance have been completed in accordance with the Law.

(iii) Upon satisfaction of the abovementioned conditions, Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx and the Offeror will comply as following:

(a) Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx shall transfer the ownership of 7’765,604 HG Shares (the “HG Ownership Rights Shares”) to the Offeror and the Offeror shall pay as consideration for the ownership of the HG Ownership Rights Shares the OPA Consideration, and the transfer shall occur through the LSE and under LSE regulations and the applicable Law.

(b) In case the HG Shares Encumbrance is partially cancelled, Xx. Xxxxx Xxxxx and Xxx. Xxxx Xxxxxx shall transfer the released HG Shares in a 1:1 ratio: the Ownership Rights of 50% of the released HG Shares shall be transferred to the Offeror and the Political Rights of the other 50% of the released HG Shares shall be transferred to the Trust. This Section 4(iii)(b) shall not be applicable if only the encumbrance over the Tori Shares is cancelled, pursuant to Section 5(i) of this Supplementary Agreement.

5. Xxx. Xxxx Xxxxxx’x Shares

(i) If during the term of this Supplementary Agreement the division of joint property referred to in Section 1(i) is registered in Cavali S.A. ICLV and, accordingly, Xxx. Xxxx Xxxxxx becomes the registered owner of 7’765,604 HG Shares (the “Tori Shares”), and then the HG Shares Encumbrance is released only over the Tori Shares (with the rest of the HG Shares remaining encumbered), Xxx. Xxxx Xxxxxx will be entitled to and shall transfer to the Offeror the Tori Shares as provided in Section 4(iii) of this Supplementary Agreement.

(ii) The Parties hereby agree that if the HG Shares Encumbrance is released over all HG Shares (including the Tori Shares) after the division of joint property referred to in Section 1(i) is registered in Cavali S.A. ICLV, then 7’765,604 HG Shares shall be transferred to the Offeror pursuant Section 4(iii)(a) and 7’765,604 HG Shares shall be transferred to the Trust, pursuant to Section 3.

6. Miscellaneous

(i) The parties hereby recognize that this Supplementary Agreement complements the TOSA and the Trust Agreement, as applicable. The TOSA and the Trust Agreement shall prevail in case of any conflict among the provisions of this Supplementary Agreement and the TOSA and the Trust Agreement.

(ii) Xxx. Xxxx Xxxxxx intervenes in this Supplementary Agreement to acknowledge the transaction contained herein and accept the terms of all Transaction Documents. Accordingly, once the division of joint property referred to in Section 1(i) is registered in Cavali and Xxx. Xxxx Xxxxxx is the owner of record, then all obligations referred to as obligations of Xx. Xxxxx Xxxxx in this Supplementary Agreement and the other Transaction Documents shall be referred to as obligations of Xxx. Xxxx Xxxxxx, and from such date, Xxx. Xxxx Xxxxxx shall be considered as a Seller under the TOSA and a “Fideicomitente” under the Trust Agreement.

IN WITNESS WHEREOF, each of the Offeror and Xx. Xxxxx Xxxxx has caused this Supplementary Agreement to be executed by its respective officers thereunto duly authorized.
