     1        that the amendment was adopted at the second meeting of
              the parties to the Montreal Protocol on Substances that
     2        Deplete the Ozone Layer in London on 27- 29 June, 1990.
              A.   Yes.  I would also like to draw your attention to the
     3        fact that it was noted in previous documents that not all
              the parties to the agreement had to actually adopt it in
     4        order that it be ratified.  It was a majority, and I think
              if one looks through this, the majority of the people who
     5        were at the meeting did in fact adopt it, notwithstanding
              the fact that it was not accepted by the United Kingdom.
     6
         Q.   Do you know whether the United States adopted it?
     7        A.   I am certain that the United States did adopt it.
 
     8   Q.   You are certain that they did?
              A.   Yes.
     9
         Q.   Can we go back to the orange file where if you turn to
    10        Section B, you will find the SORG Report, or Review, for
              1988.
    11        A.   Yes.
 
    12   Q.   Can you please turn to the executive summary which is on
              the sixth page.  Page 459 of the bundle.  I am not going
    13        to read all of this.  Happily the paragraphs are numbered.
 
    14         "1.  Since the last report from the Group, in 1987, it
              has become clear that significant depletion of the
    15        stratospheric ozone layer results from man's activities."
 
    16        Can I put words into your mouth: Is that when the light
              fully dawned during that period?
    17        A.   It is when the experimental campaigns of 1986 and
              1987 had had their data evaluated so that in fact the
    18        predictions could be checked.
 
    19   Q.   Then there is a bit of history at the beginning of
              paragraph 2 and then it says,
    20
              "It is now virtually certain that the depletion is caused
    21        by man- made chlorofluorocarbons (CFCs) in an atmosphere
              which has been pre- conditioned by processes involving
    22        polar stratospheric clouds."  (What you earlier described
              as PSCs)
    23        A.   Indeed.
 
    24   Q.   Is that the process which you described in a little more
              detail earlier on today?
    25        A.   It is.
  
    26   Q.   Would you look at paragraph 5? 
              "In the absence of other changes, the Antarctic ozone hole 
    27        will continue to appear each year until stratospheric
              chlorine levels fall to those of the mid- 1970s.  Even if
    28        no more man- made chlorine were to be released into the
              atmosphere, this would take many decades."
    29
              "8.  Models predict that, even with CFC emissions assumed
    30        to result from the Montreal Protocol, chlorine in the
              stratosphere will double over the next fifty years.  To
