(c)
Oral testimony of the content of a writing is not made inadmissible by subdivision (a) if the proponent does not have possession or control of the original or a copy of the writing and either of the following conditions is satisfied:
(1)
Neither the writing nor a copy of the writing was reasonably procurable by the proponent by use of the court’s process or by other available means.
