                  (i)      AT CLOSE OF ESCROW, THE $7,000,000 PURCHASE PRICE
                           SHALL BE PAID BY SENIOR CARE INTERNATIONAL BY HAVING
                           SENIOR CARE INDUSTRIES ISSUE 150,000 SHARES OF SERIES
                           "F" CONVERTIBLE PREFERRED STOCK CONVERTIBLE 20 TO 1
                           INTO RULE 144 COMMON STOCK UNDER A CONVERSION FORMULA
                           WHEREIN 20% OF THE PREFERRED STOCK MAY BE CONVERTED
                           TO RULE 144 COMMON STOCK IN THE 24TH MONTH AFTER OF
                           THE ACQUISITION BY SENIOR CARE CLOSE (THE FIRST
                           CONVERSION DATE) AND

                  (ii)     EACH SUCCESSIVE ONE YEAR PERIOD FOLLOWING THE FIRST
                           CONVERSION DATE. (1)

                  (iii)    SENIOR CARE TO HAVE AN IRREVOCABLE OPTION TO ACQUIRE
                           UP TO 100% OF THE 144 STOCK CREATED BY THE CONVERSION
                           ON EACH CONVERSION DATE ON A PRO-RATA BASIS IN
                           INCREMENTS UP TO 1,400,000 AT EACH CONVERSION. (2)

--------
(1) On the 24th month following the close of escrow and for each successive one
year period following the first conversion date, the number of preferred shares
converted shall be adjusted to reflect the average ask price of the rule 144
common stock at time of each conversion, for the prior 10 day period. The amount

<PAGE>

of stock to be converted each conversion date shall equal 20% of the purchase
price Example: Based upon the purchase price of $7,000,000, the balance to be
paid through the conversion of preferred stock on the each conversion date would
equal ($7,000,000 * 20% = $1,400,000 on each conversion date. If on the 24 month
after close, the average ask price is $2.50 per share, 28,000 shares of
preferred stock would be converted at a 20 to 1 conversion netting the seller
(28,000 * 20) = 560,000 shares of rule 144 common stock valued at $2.50 per
share for a total of $1,400,000. The same formula will be applied on each
successive one- year period following first conversion date, such that, if on
next conversion date, the average ask price is $5.00 per share, 14,000 shares of
preferred stock would be converted at a 20 to 1 conversion netting the seller
(14,000 * 20) = 280,000 shares of rule 144 common stock valued at $5.00 per
share for a total of $1,400,000 and so on, such that for each successive
conversion, the total shares converted under the formula will reflect the
average stock price. At the end of the fifth conversion, any preferred stock
that is not required for conversion in order to pay the full purchase price
shall be returned to the SENR treasury. In the alternative, additional preferred
stock shall be issued to Seller in the event that the ask price under the
conversion formula results in a requirement for more stock to be issued in order
for Seller to receive the full sales price.

(2) On each conversion date,$1,400,000 worth of stock may be converted by the
Seller pursuant to footnote # 1. Senor Care to have up to 30 days after the/
stock converts to acquire all or a portion of the $1,400,000 in stock. The stock
may not be sold or hypothecated to a third party within said 30 day period and
the party converting the stock shall assign its voting rights to the Board of
Directors of Senior Care the day the stock converts and Senior Care's Board
shall have the right to "vote the stock" within said 30 day period.

liabilities, obligations, promises, agreements, controversies, damages, actions,
causes of action, suits, rights, demands, costs, losses, debts, judgments and
expenses of any nature whatsoever (any of the foregoing, a "Claim"), known or
unknown, suspected or unsuspected, fixed or contingent which Seller now has,
owns, holds, or claims to have, claims to own, or claims to hold, or which
Seller at any time heretofore had, owned, held or claimed to have, claimed to
own, or claimed to have held, or which Seller at any time hereafter may have,
own, hold or claim to have, claim to own, or claim to hold, against the Company

to Seller's purchase and ownership of the Shares and any other securities of the
Company previously owned by Seller, the sale of the Shares pursuant to this
Agreement and any prior sales of securities of the Company, including but not
limited to any Claim asserted or assertable by Seller pursuant to Section 10(b)
and Rule 10b-5 of the Exchange Act. For the purposes of implementing a full and
complete release and discharge of the Company and the other Released Parties,

to the aforesaid which Seller does not know or suspect to exist in its favor at
the time it signs this Agreement, and that this Agreement is intended to fully
and finally resolve any such Claim or Claims. Nothing contained herein shall
adversely affect any of Savoy's rights to indemnification by contract, law, the
Certificate of Incorporation or Bylaws of the Company or under any insurance
coverage.
