13th. Should the Maharajah require the aid of any of the Shah’s troops in furtherance of the object contemplated by this treaty, the Shah engages to send a force commanded by one of his principal officers; in like manner, the Maharajah will furnish the Shah, when required, with an auxiliary force composed of Mahomedans, and commanded by one of his principal officers as far as Caubul, in furtherance of the objects contemplated by this treaty. When the Maharajah may go to Peshawur, the Shah will depute a Shah-zadah to visit him; on which occasions the Maharajah will receive and dismiss him with the honour and consideration due to his rank and dignity. 14th. The friends and enemies of each of the three high powers—that is to say, the British and Sikh Governments and Shah Soojah-ool-Moolk, shall be the friends and enemies of all. 15th. Shah Soojah-ool-Moolk agrees to relinquish for himself, his heirs, and successors, all claims of supremacy and arrears of tribute over the country now held by the Ameers of Sindh (which will continue to belong to the Ameers and their successors in perpetuity), on condition of the payment to him by the Ameers of such a sum as may be determined, under the mediation of the British Government, of such payment being made over by him to Maharajah Runjeet Singh. On these payments being completed, article 4 of the treaty of the 12th of March, 1833, will be considered cancelled, and the customary interchange of letters and suitable presents between the Maharajah and the Ameers of Sindh shall be maintained as heretofore. 16th. Shah Soojah engages, after the attainment of his object, to pay without fail to the Maharajah the sum of two lakhs of rupees of the Nanukshahee or Kuldar currency, calculating from the date on which the Sikh troops may be despatched for the purpose of reinstating his Majesty in Caubul, in consideration of the Maharajah stationing a force of not less than 5000 men—cavalry and infantry—of the Mohamedan persuasion, within the limits of the Peshawur territory for the support of the Shah, and to be sent to the aid of his Majesty whenever the British Government, in concert and counsel with the Maharajah, shall deem the aid necessary; and when any matter of great importance may arise to the westward, such measures will be adopted with regard to it as may seem expedient and proper at the time to the British and Sikh Governments. In the event of the Maharajah requiring the aid of the Shah’s troops, a deduction shall be made from the subsidy proportioned to the period for which such aid may be afforded; and the British Government holds itself responsible for the punctual payment of the above sum annually to the Maharajah, so long as the provisions of this treaty are duly observed. 17th. When Shah Soojah-ool-Moolk shall have succeeded in establishing his authority in Afghanistan, he shall not attack or molest his nephew, the ruler of Herat, in the possession of his territories, now subject to his government.
