`Declaration under 37 C.F.R. 4 1.132
`
`I, Dr. Jorg Kaufmann, declare and say:
`
`1.
`
`I am an inventor of the captioned application..
`
`2.
`
`I make this declaration to explain how to calculate the number of possible ways of
`
`arranging 2'- modified and unmodified nucleotides on antisense and sense strands of a double
`
`stranded RNA molecule where each strand is 23 nucleotides long.
`
`3.
`
`In a double stranded RNA molecule of this type, any nucleotide on either strand
`
`can be either modified or unmodified. In other words, there are two possibilities for each
`
`position. Thus, on a single strand that is n nucleotides long, there are 2" possible ways of
`arranging modified and unmodified nucleotides on the strand. For example, each strand might
`
`be completely unmodified, might have from 1 to 22 modifications arranged in any possible
`
`combination of positions in the strand, or might be modified on every nucleotide.
`
`On a strand containing 23 nucleotides, there are therefore 223 possible ways of
`4.
`arranging modified and unmodified nucleotides along the strand.

`
`5.
`
`In a double stranded molecule where each strand is 23 nucleotides long, there are
`
`223 possible ways of arranging modified and unmodified nucleotides on each strand, and the
`
`arrangements on each strand are independent. Accordingly, in such a double stranded molecule
`
`there are 223 x 223 = 246 =7.0 x 10" possible arrangements.
`
`6.
`
`All statements made herein of my knowledge are true and all statements made on
`
`information and belief are believed to be true; and further, these statements are made with the
`
`knowledge that willful false statements and the like so made are punishable by fine or
`imprisonment, or both, under 18 U.S.C. § 1001 and that such willful false statements may
`
`jeopardize the validity of the application or any document or any registration resulting therefrom.
