Re: Opinion of Counsel - Registration Statement on Form S-1

Gentleman:

     I have acted as counsel for Tri-Mark in connection with the
preparation and filing of Tri-Mark's Registration Statement on Form S-1
under the Securities Act of 1933, as amended, (the "Registration
Statement"), relating to 1,000,000 common shares of Tri-Mark.

     I have examined the Certificate of Incorporation, as amended, and
the By-Laws of Tri-Mark and all amendments thereto, the Registration
Statement and originals, or copies certified to my satisfaction, of
such records and meetings, written actions in lieu of meetings, or
resolutions adopted at meetings, of the directors of Tri-Mark, and such
other documents and instruments as in my judgment are necessary or
appropriate to enable me to render the opinions expressed below.

     Based on the foregoing examination, I am of the opinion that the
securities being registered are duly authorized and, when issued in
accordance with Registration Statement, will be validly issued, fully
paid and non assessable.

     Further, I consent to the filing of this opinion as an exhibit to
the Registration Statement.


Very truly yours,


/s/ Jody M. Walker
