   *  Where a range of ODPs is indicated, the highest value in that 
range shall be used for the purposes of the Protocol. The ODPs listed 
as a single value have been determined from calculations based on 
laboratory measurements.  Those listed as a range are based on 
estimates and are less certain.  The range pertains to an isomeric 
group.  The upper value is the estimate of the ODP of the isomer with 
the highest ODP, and the lower value is the estimate of the ODP of the 
isomer with the lowest ODP.

listed against them to be used for the purposes of the Protocol.

            ARTICLE 2:  RELATIONSHIP TO THE 1990 AMENDMENT 

   No State or regional economic integration organization may deposit 
an instrument of ratification, acceptance, approval or accession to 
this Amendment unless it has previously, or simultaneously, deposited 
such an instrument to the Amendment adopted at the Second Meeting of 
the Parties in London, 29 June 1990. 

                   ARTICLE 3:  ENTRY INTO FORCE 

1. This Amendment shall enter into force on 1 January 1994, provided 
that at least twenty instruments of ratification, acceptance or 
approval of the Amendment have been deposited by States or regional 
economic integration organizations that are Parties to the Montreal 
Protocol on Substances that Deplete the Ozone Layer.  In the event 
that this condition has not been fulfilled by that date, the Amendment 
shall enter into force on the ninetieth day following the date on 
which it has been fulfilled. 

2. For the purposes of paragraph 1, any such instrument deposited by 
a regional economic integration organization shall not be counted as 
additional to those deposited by member States of such organization. 

3. After the entry into force of this Amendment, as provided under 
paragraph 1, it shall enter into force for any other Party to the 
Protocol on the ninetieth day following the date of deposit of its 
instrument of ratification, acceptance or approval.
