                                    Between

                     (Formerly US Facilities Corporation)

                               David L. Cargile
                       ________________________________



   Whereas, The Centris Group, Inc., a Delaware corporation (the "Company"), and
David L. Cargile (the "Executive") entered into a Severance Agreement dated May
24, 1994, and to an Amendment No. 1 thereto dated December 4, 1996 (collectively
referred to herein as the "Agreement"), which relates to the termination of
Executive's employment with the Company under certain circumstances; and

   Whereas, the Company and the Executive desire to amend Section 4(e)(i) to
clarify the definition of events which constitute a "Change in Control" for
purposes of this Agreement;

   Now, Therefore, in consideration of the Company's agreement to continue the
employment of Executive for a period of a minimum of six (6) months from the
date of this Amendment and the payment to Executive of $1.00 and other good and
valuable consideration, receipt of which is hereby acknowledged, the Company and
the Executive hereby agree to enter into this Amendment to the Agreement as
follows:

   1. Section 4(e)(i) of the Agreement as originally written shall be stricken
and eliminated from the Agreement, and shall be completely replaced by a new
Section 4(e)(i), which shall read in full as follows:

         (i) At any time during the term of this Agreement, any "Person" (as
   such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act
   of 1934 (the "Exchange Act") and the regulations of the Securities and
   Exchange Commission (the "SEC") thereunder, each as in effect on the
   Effective Date of this Agreement (including any such 
<PAGE>
 
   Persons that may be deemed to be acting in concert with respect to the
   Company or the acquisition, ownership or voting of Company securities)
   becomes, directly or indirectly, the "Beneficial Owner" (as defined in Rule
   13d-3 under the Exchange Act and the regulations of the SEC thereunder, each
   as in effect on the Effective Date of this Agreement), without the prior
   approval of the Board of Direcors of the Company, of outstanding securities
   of the Company representing 15% or more of the combined voting power of the
   Company's then outstanding securities; provided, however, that the concept of
   any Person becoming the owner of 15% or more of the combined voting shares
   shall not include: (A) the Company, any wholly owned subsidiary of the
   Company, any employee benefit plan of the Company or of a subsidiary of the
   Company, or any Person holding voting shares for or pursuant to the terms of
   any such employee benefit plan; or (B) any Person if such Person would not
   otherwise be a 15% stockholder but for a reduction in the number of
   outstanding voting shares resulting from a stock repurchase program or other
   similar plan instituted by the Company or from a self-tender offer of the
   Company, which stock repurchase plan or Company self-tender offer commenced
   on or after the Effective Date of this Agreement; provided, however, that the
   concept of becoming the owner of 15% or more of the combined voting shares
   shall include such Beneficial Owner after the first date upon which (x) such
   Person, since the date of commencement of such stock repurchase plan or
   Company self-tender offer, shall have acquired Beneficial Ownership of, in
   the aggregate, additional voting shares of the Company representing 1% or
   more of the voting shares then outstanding, and (y) such Person, together
   with all affiliates and associates of such Person, shall Beneficially Own 15%
   or more of the voting shares of the Company then outstanding. In calculating
   the percentage of outstanding voting shares that are Beneficially Owned by a
   Person for purposes of this subsection, voting shares that are Beneficially
   Owned by such Person shall be deemed outstanding, and voting shares that are
   not Beneficially Owned by such Person and that are subject to issuance upon
   the exercise or conversion of outstanding conversion rights, exchange rights,
   warrants or options shall not be deemed outstanding. The Board of Directors
   shall have the absolute and unfettered authority to make the final
   determination as to whether any Person is or is not to be considered a 15%
   Stockholder for purposes of this Agreement, which determination shall be
   conclusive for all purposes and shall be binding upon the Company and upon
   the Executive.

   2. This Amendment shall be retroactive and shall be considered and deemed to
have been in effect as of May 24, 1994, the Effective Date of the Agreement,
which is the date when it was entered into by the parties hereto.

   3. Apart from this Amendment, the terms of the Agreement as entered into on
May 24, 1994 and as amended by Amendment No. 1 on December 4, 1996 shall
otherwise in all respects remain as originally written to the extent that such
terms do not conflict with or are inconsistent with this Amendment.
