The body shall convene whenever it is necessary at a request by its representative, by the company or by a number of bondholders owning 10% of its value. The invitation shall be made in the same manner referred to in the foregoing paragraph including the agenda. The resolutions passed by the body shall not be valid unless the meeting is attended by a number of bondholders representing two thirds of the issued bonds. If the quorum is not available, the body shall be invited to convene a second meeting for the same agenda, and such meeting shall be valid if it is attended by bondholders representing one third of the bonds. The resolutions shall be issued by the majority of the bondholders attending the meeting. If the resolution has to do with the extension of the maturity of bonds, reduction of the return or the loan amount or if it has to do with the guarantees or if it prejudices in any way whatsoever the rights of the bondholders, it shall be valid only if it is approved by bondholders representing two thirds of the loan bonds. In all cases, the body shall not issue any resolution that might result in increasing the obligations of its members or prejudicing the principle of equality among them.
