with the business of VARIFLEX and its representative shall not disclose to any
other person, firm or corporation any information acquired as a result of such
examination.

Patent.

     12.03.  PRD and RICH shall file foreign patent applications for the
Licensed Intellectual Property in the following jurisdictions:  Mexico, Canada

filing in the EPO, after which amount has been reached, any further expenses and
costs shall be the responsibility of VARIFLEX.  VARIFLEX may decide to file
patent applications in other foreign countries and PRD and RICH shall cooperate
as reasonably necessary to file in such other foreign countries.  All fees and
costs for filing applications in such other foreign countries shall be the
responsibility of VARIFLEX.  Each party shall keep the other party promptly
informed of the prosecution of any foreign filed application and shall provide
the other party with an opportunity to review and comment on all substantive

pursued by PRD and RICH.  Fees and expenses resulting from the exercise of
VARIFLEX's rights under the preceding sentence shall be divided equally between
PRD and RICH, on the one hand, and VARIFLEX, on the other hand.  At PRD and

ARTICLE XIII.  INDEMNIFICATION AND INSURANCE

     13.01.  Indemnification. PRD and RICH, both collectively and individually

                             ESTOPPEL CERTIFICATE
                             --------------------

     I, JOSIE RICH, do hereby acknowledge, certify, represent, warrant and
covenant as follows:

     1.  I am the wife of Wayne Rich. Our address is 3513 Gillionville Road,
Albany, Georgia 31707.

     2.  I have received a copy of the Exclusive License Agreement, effective
December 1, 1998 (the "License Agreement"). The parties are Wayne Rich, Product
Resource & Development Inc., a Georgia corporation ("PRD") and Variflex, Inc., a
Delaware corporation ("Variflex") (collectively, the "Parties"). I am familiar
with the general purpose and contents of the License Agreement. If capitalized
terms are used in this Estoppel Certificate and not otherwise defined, they
shall have the meanings given them in the License Agreement.

     3.  It was originally contemplated that I would be a party to the License
Agreement. However, I have advised the Parties that I have no right, title or
interest in the License Agreement or the Licensed Product, Licensed Intellectual
Property, Licensed Improvements, Optioned Improvements or Issued Patent referred
to therein (collectively, the "Licensed Property"). Therefore, at my initiative
and request, Variflex agreed that it would not insist that I be a party to the
License Agreement if I executed and delivered this Estoppel Certificate.

     4.  I acknowledge and understand that Variflex would not enter into the
License Agreement if I did not become a party thereto or execute and deliver
this Estoppel Certificate. I am executing and delivering this Estoppel
Certificate for the express purpose of inducing Variflex to enter into the
License Agreement without me being a party thereto and Variflex has agreed to do
so in consideration for my execution and delivery of this Estoppel Certificate.

                                  Page 2 of 3

     5.  I have absolutely no right, title or interest, direct or indirect,
contingent or remote in (a) the License Agreement, (b) any of the Licensed
Property, (c) any modifications, amendments, supplements, extensions or renewals
of the License Agreement, or (d) any agreement entered into in the future which
is or was contemplated under the License Agreement.  The Parties shall have the
absolute right to enter into such modifications, amendments, supplements,
extensions, renewals or future agreements as they deem appropriate without my
knowledge or consent.  When used in this Estoppel Certificate the term License
Agreement shall mean the License Agreement and all such modifications,
amendments, supplements, extensions, renewals and future agreements.

     6.  Except for rights acquired pursuant to a permitted assignment under
Section 16.02 of the License Agreement and except for rights acquired by
operation of the laws of intestate succession or through the will of Wayne Rich,
if for any reason I do own or hold, or am deemed to own or hold, any right,
title or interest in the License Agreement or any of the Licensed Property, or I
hereafter acquire or am deemed to have acquired any such right, title or
interest, I hereby unconditionally and irrevocably assign and transfer all such
rights, titles and interests to Wayne Rich, including, without limitation, any
rights, titles or interests I may have  or hereafter acquire under applicable
community property or other laws as a result of my status as the wife of Wayne
Rich.

     7.  I understand that I was a party to certain of the agreements listed in
Exhibit D to the License Agreement.  To the best of my knowledge and belief,
none of the obligations, duties, covenants and other commitments made and
provided by PRD and/or Wayne Rich in the License Agreement violate, directly or
indirectly, any of the agreements listed in Exhibit D to the License Agreement
and the sale to Variflex or license by Variflex of the Licensed Product under
the License Agreement for resale by Variflex does not violate any of the
agreements listed in Exhibit D to the License Agreement.

     8.  I will not engage in or take, or permit or allow anyone else to engage
in or take, on my behalf or for my benefit, any conduct or action which is or
may be construed to be inconsistent with any of the representations, warranties,
certifications or covenants set forth in this Estoppel Certificate.

     9.  Variflex, and its successors and assigns, are entitled to rely upon
this Estoppel Certificate. I acknowledge and understand that Variflex is relying
upon the truth, accuracy, and binding effect of this Estoppel Certificate in
entering into the License Agreement.

     10. I have been advised and represented by George Ellis my separate and
independent legal counsel of my choice in connection with this Estoppel
Certificate and the matters referred to herein.

     11. I agree that since Variflex and its legal counsel are located in
California, the interpretation, effect and enforceability of this Estoppel
Certificate shall be governed by the laws of the State of California (excluding
its conflict of laws).
