            ---------------------                --------------------

          Stock     $ 2,000,000                      Paid May 22, 2001
          Warrants  $ 7,000,000                      Paid May 22, 2001

* (Set forth the amount on which the filing fee is calculated and state how it
was determined.) The Transaction Valuation is based upon the market price of the
securities to be received by Senior Care Industries, Inc. pursuant to Regulation
230.457(f)(1) with the value based upon the price of the securities subject to
the tender as of May 10, 2001 as set forth in Rule Regulation 230.457c. This
calculation is based as follows:

Number of potential shares to be tendered: 20,000,000
Price of those shares on May 10, 2001:    $.10

Additionally, for each three shares tendered, the shareholder tendering those
shares will receive 1 warrant in Senior Care Industries, Inc. The warrant
calculation is based upon Regulation 230.457(g)(2) where the calculation is
based upon the warrant price which is $1 per warrant. This calculation is based
as follows:

Estimated number of warrants: 7,000,000
Warrant price:                    $1.00

Additionally, the Company will immediately issue the following press release and

240.13(e)(4)(c)(1) as follows:

SENIOR CARE EXTENDS ITS TENDER OFFER TO TRI-NATIONAL SHAREHOLDERS LAGUNA BEACH,
Calif., August 28, 2001 -- Senior Care Industries, Inc. [OTCBB: SENC] announced
today that it is extending its tender offer to Tri-National Development
Corporation [OTCBB: TNAV] shareholders by an additional 60 days. The offer which
had scheduled to end on August 31, 2001 will now be extended through October 31,
2001. Senior Care said the primary reason for the extension was twofold. First
of all, Senior Care is still in the process of responding to comments on Senior
Care's registrations statement from the Securities & Exchange Commission.
Following the comment process, a prospectus will be mailed to all Tri-National
shareholders. Secondly, Tri-National shareholders need time to assess the impact
of the involuntary Chapter 11 Petition filed against Tri-National on August 23,
2001. The Petition, filed by major creditors of Tri-National including Senior
Care, was filed in the U. S. Bankruptcy Court in the Southern District of
California, in San Diego. Tri-National must respond no later than September 12,
2001 to submit a motion or answer to the Petition and appear before Judge John
J. Hargrove in San Diego who has been assigned to the case. A state court
receiver had earlier taken possession of Tri-National's United States assets in
June of this year. The receiver had been requested in court proceedings
initiated by Capital Trust, Inc. [NYSE: CT], to whom Tri-National owes more than
$8,000,000. Capital Trust obtained a judgment against not only Tri-National, but
also against certain officers and directors. Tri-National is also delinquent in
payments to over 300 bondholders to whom it owes another $11,000,000.

Senior Care is presently developing 233 single family senior "smart homes" near
Palm Springs, California and 54 town houses in Las Vegas, Nevada. Sales of
Senior Care's Evergreen Manor II condominium project in Los Angeles, California,
have been brisk, according to management. All Senior Care properties are
developed for the senior market.

Senior Care also owns Noble Concepts, a manufacturer of high-quality "Craftsman
Mission" furniture which is distributed throughout the United States to a
variety of furniture retailers. Senior Care also uses Noble to furnish its
models and rental units.
