ITEM 4.  DESCRIPTION OF SECURITIES

     Not Applicable.

ITEM 5.  INTEREST OF NAMED EXPERTS AND COUNSEL

     The consolidated financial statements and schedules of UICI appearing in
UICI's Annual Report (Form 10-K) for the year ended December 31, 1999, have been
audited by Ernst & Young LLP, independent auditors, as set forth in their report
thereon included therein and incorporated herein by reference. Such consolidated
financial statements are incorporated herein by reference in reliance upon such
report given on the authority of such firm as experts in accounting and
auditing.

     The legality of the shares of the common stock of UICI to be issued in
connection with the UICI Plans IS being passed upon for UICI by Glenn W. Reed,
Executive Vice President and General Counsel of UICI. At June 30, 2000, Mr. Reed
was the beneficial owner of 33,929.42 shares of UICI common stock.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the General Corporation Law of Delaware authorizes
indemnification of directors, officers and employees of Delaware corporations.

directors and officers (the "Indemnitees") under specified circumstances to the
fullest extent authorized by the General Corporation Law of Delaware, (ii)
provides for the advancement


<PAGE>   3

of expenses to the Indemnitees for defending any proceedings related to the
specified circumstances, (iii) gives the Indemnitees the right to bring suit
against the registrant to enforce the foregoing rights to indemnification and
advancement of expenses, and (iv) authorizes the registrant to maintain certain
policies of insurance to protect itself and any of its directors, officers or
employees. The registrant has an insurance policy covering its directors and
officers against certain personal liability, which may include liabilities under
the Securities Act of 1933 as amended.

ITEM 9.  UNDERTAKINGS

A.   Updating Disclosure

The undersigned registrant hereby undertakes:

(1)  To file, during any period in which offers of sales are being made, a
     post-effective amendment to this registration statement:

     (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

     (ii) To reflect in the prospectus any facts or events arising after the
          effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the effective registration
          statement;


<PAGE>   4

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement;

Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

(2)  That, for the purpose of determining any liability under the Securities Act
     of 1933, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

(3)  To remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering.

B.   Subsequent Exchange Act Documents.

The undersigned registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

C.   Indemnification.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer of controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

ITEM 9.  UNDERTAKINGS

A.   Updating Disclosure

The undersigned registrant hereby undertakes:

(1)  To file, during any period in which offers of sales are being made, a
     post-effective amendment to this registration statement:

     (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

     (ii) To reflect in the prospectus any facts or events arising after the
          effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20% change in the maximum aggregate offering price set forth in the
          "Calculation of Registration Fee" table in the effective registration
          statement;
4

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement;

Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

(2)  That, for the purpose of determining any liability under the Securities Act
     of 1933, each such post-effective amendment shall be deemed to be a new
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.

(3)  To remove from registration by means of a post-effective amendment any of
     the securities being registered which remain unsold at the termination of
     the offering.

B.   Subsequent Exchange Act Documents.

The undersigned registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

C.   Indemnification.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer of controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
