June 7, 2006

Mr. Younis Zubchevich
General Manager
Gryphon Opportunities Fund I, LLC
400 Royal Palm Way
Suite 300
Palm Beach, FL  33480

Dear Younis,

Due to the on-going lack of investment capital for SecureCARE Technologies,
Inc., (the "Company"), I am writing to you on behalf of the board of directors
and company management to ask for your approval in regard to certain changes in
the Company's debt and capital structures. These changes will allow the Company
to raise the short-term and long-term investment capital needed to cover its
critical liabilities, to fund its current operations and planned technology
investments and fund its long-term business plan. Highlights of the Company's
debt and capital structure are indicated below. Additional detail is provided in
attachments one and two.

Past Bridge Financing/Accrued Interest                               $ 2,039,162
Recent Bridge Financing                                              $    70,000
Common Stock Outstanding                                              20,304,000
Fully Diluted Shares Outstanding                                      26,623,455
Short-Term Bridge Financing "To Be Raised"                           $   500,000

In order to raise the required short-term financing of $500,000 and additional
growth capital in the future of $1 - $2 Million, we must restructure the
Company's balance sheet as follows:

         1.       The existing shareholders and warrant holders, on a
                  fully-diluted basis (26,623,455 shares currently outstanding)
                  will, in the restructured Company, represent 10 percent
                  ownership of the total common stock shares outstanding in the
                  Company, post-restructure.

         2.       According to my records, as of March 31, 2006, on a fully
                  diluted basis, Gryphon Opportunities Fund I, LLC ("Gryphon")
                  owns 13,482,638 shares of SecureCARE Technologies, Inc. common
                  stock. In addition, your affiliated entities (Dall, Inc., York
                  Avenue Holding Corporation and Gryphon Financial Securities
                  Corporation) own a total of 420,300 shares of common stock and
                  466,727 common stock purchase warrants. This amounts to
                  Gryphon and its affiliated entities' total holdings of
                  14,369,665 on a fully-diluted basis.

                                       3755 Capital of Texas Highway, Suite 160E
                                                               Austin, TX  78704
                                                         Telephone: 512-589-6754
                                                               Fax: 512-439-6760
                                                              EFax: 703-783-8407
                                                          www.securecaretech.com

 SecureCARE
 Technologies, Inc.

         3.       Investors who provided bridge financing ($2,609,162, including
                  accrued interest) over the last three years, including the
                  $544,490 in principal plus accrued interest provided by
                  Gryphon during the period of the Company's reorganization in
                  2003, and the $70k recently received and the $500k to be
                  raised in the next two weeks, will represent 90 percent
                  ownership of the total common stock shares outstanding in the
                  Company, post-restructure.

Once these arrangements have been completed, there will be approximately 266
million common shares outstanding as follows:

239,611,095   Bridge Financing Ownership (90%)
 26,623,455   Fully Diluted Common stock Ownership (10%)
266,234,500   Total Shares Outstanding

We propose a forward reverse-split of the shares on a 200:1 basis, resulting in
total common shares outstanding, post-recapitalization of 1,331,172. We also
believe that we will be able to reconstruct the balance sheet in a way in which
total assets will be approximately $1.3 million.

This recapitalization reflects equal treatment for all shareholders and note
holders (creditors).

In the past two weeks, $70,000 in investment capital has been received by the
Company from existing investors. Among other things, these funds were used to
pay the audit firm, as required, so the year-end 2005 audit could be completed
and the Company's annual report filed with the SEC. This allowed the Company to
keep its listing with the NASD.

Additionally, $500,000 in additional investment capital must be found in the
next two weeks to enable the Company to manage its on-going liabilities, fund
its existing operations and short-term technology investments and allow for the
additional time required for a further long-term investment of up to $2 Million.

This is to confirm that you agree that a recapitalization of the Company is in
order to facilitate additional financing. Included in this agreement are the
following conditions:

         1)       Gryphon Opportunities Fund I, LLC, Gryphon Financial
                  Securities Corp. and all of their officers, employees,
                  affiliates and directors will receive an indemnification from
                  the Company with respect to this contemplated recapitalization
                  plan, and will also receive a release waiver from the Company
                  with respect to all of its activities related to the Company.

         2)       The lien on the assets of the Company will be released to the
                  Company alone, and no other entity, upon closing of the
                  initial $500,000 in investment capital contemplated in this
                  plan. Until the Company raises an additional $1,000,000 in
                  investment capital over the initial $500,000, no other entity
                  other than the Company shall be granted a lien on the assets
                  of the Company without the prior express approval of Gryphon

                  Opportunities Fund I, LLC. When the Company raises an
                  additional $1,000,000 in investment capital, Gryphon
                  Opportunities Fund I, LLC will relinquish all of its rights in
                  regard to the Company's assets, including elimination of the
                  requirement of the Company to obtain prior express approval of
                  Gryphon Opportunities Fund I, LLC to grant a lien on its
                  assets to any other entity.

         3)       The Company undertakes to work with all the creditors and
                  investors to obtain all consents necessary to effectuate this
                  plan. Gryphon and its Affiliated entities will not take
                  responsibility for obtaining such consents although it may be
                  asked from time to time to render its assistance.

         4)       The note payable to Phoebe Holdings, totaling $63,500 in
                  principal plus accrued interest will be assigned to York
                  Avenue Holding Corp. by the Company upon receipt of the
                  appropriate and complete documentation by York Avenue Holding
                  Corp., to be reviewed and approved by the Company's SEC
                  attorney.

         5)       All existing shareholders are treated on a Pari Passu basis.

         6)       Younis Zubchevich maintains observer status on the Board of
                  Directors for the next three years with the right to attend
                  all meetings and receive all information disseminated to the
                  Board of Directors at the same time the information is issued
                  to the Board members. In addition, for the next three years,
                  Mr. Zubchevich has the right to nominate a position on the
                  Board of Directors. This nomination is subject to approval of
                  the Board of Directors.

Once these arrangements have been completed, there will be approximately 266
million common shares outstanding as follows:

239,611,095   Bridge Financing Ownership (90%)
 26,623,455   Fully Diluted Common stock Ownership (10%)
266,234,500   Total Shares Outstanding

We propose a forward reverse-split of the shares on a 200:1 basis, resulting in
total common shares outstanding, post-recapitalization of 1,331,172. We also
believe that we will be able to reconstruct the balance sheet in a way in which
total assets will be approximately $1 million.

This recapitalization reflects equal treatment for all shareholders and note
holders (creditors).

Please indicate your approval of SecureCARE's balance sheet recapitalization and
all of its terms and conditions, as indicated above, by signing below. Please

as detailed above can be calculated. Therefore, certain amounts referenced above
are subject to adjustment as of the recapitalization date.
