Exhibit 26) which Dr. Riggins had written and sent
to Benny L. Triplett . . . a senior management employee
with Burlington and Dr. Riggins’s immediate supervisor,
Mr. Triplett had handwritten a brief note at the top of
Dr. Riggins’s letter before forwarding the letter to me.
5. Dr. Riggins’s letter explained that, during
the past few months prior to the writing of his letter
to Mr. Triplett, he had identified several agents having
dye promoting capability for aromatic amide fibers such
as Nomex® fibers. Three of these dyepromoting agents
(which I understand are commonly known as “carriers”)
were identified in Dr. Riggins’s letter (Riggins et al.
Exhibit 26), namely N,N-dimethylamide, N,N-diethyl
benzamide, and N,N-dimethylformamide. In addition,
Dr. Riggins’s letter expressed that several other
chemicals of the same “family” of carriers had been
ordered so that further experimentation could be
conducted to find more carriers for dyeing Nomex®.

Haith, para. 2-5 (Record of Party Riggins et al. (Paper No. 98),
pp. 34-35 (RR 34-35)):
2. At Burlington, I worked in a laboratory shared
with several Burlington employees including Dr. Phillip H.
Riggins . . . . During the years of 1989 to 1990, I was
aware of Dr. Riggins’s work on the development of dye
promoting agents (commonly known as “carriers”) for
dyeing Nomex® fibers. It was my understanding at the
time that Nomex® fabric was difficult to dye and that
carriers were therefore needed to promote penetration
of the fibers with dyestuff.
3. During the year of 1990, I signed several
pages of Dr. Riggins’s Laboratory Notebook No. 1664 to
corroborate Dr. Riggins’s entries, signatures, and
entry dates (Riggins et al. Exhibit 22; Notebook 1664,
pp. 28-29, 31, 34-39, 42, and 47-50). . . . .
4. To my knowledge, page number 28 of Notebook 1664
concerns experimentation with several chemicals including
N,N-dibutylbenzamide and N,N-dimethyl benzamide. Page 29
of Notebook 1664 describes testing of N,N-diethylbenzamide
