Provided that where sale proceeds, or any part thereof, in respect of such export goods are not realised by the applicant within the period allowed under the Foreign Exchange Management Act, 1999 (42 of 1999), but the Reserve Bank of India writes off the requirement of realisation of sale proceeds on merits, the refund paid to the applicant shall not be recovered.

(2) Where the sale proceeds are realised by the applicant, in full or part, after the amount of refund has been recovered from him under sub-rule(1) and the applicant produces evidence about such realisation within a period of three months from the date of realization of sale proceeds, the amount so recovered shall be refunded by the proper officer, to the applicant to the extent of realisation of sale proceeds, provided the sale proceeds have been realised within such extended period as permitted by the Reserve Bank of India.
