               PROXY STATEMENT/PROSPECTUS (SUBJECT TO COMPLETION,
                             DATED OCTOBER 26, 1999)

                     HEALTHPLAN SERVICES LOGO OR LETTERHEAD

HealthPlan Services Corporation             James K. Murray, Jr.
3501 Frontage Road                          Chairman and Chief Executive Officer
Tampa, Florida  33607

Dear Stockholder:

The Board of Directors of HealthPlan Services Corporation has unanimously
approved a merger with UICI.

We expect to accomplish this merger by merging a new subsidiary of UICI into
HealthPlan Services. HealthPlan Services will be the surviving corporate entity
in the merger and will be a wholly-owned subsidiary of UICI.

In the merger, each HealthPlan Services common share will be converted into the
right to receive a specified number of shares of common stock of UICI based on
an exchange ratio that will be determined based on the average of the volume
weighted averages of the trading prices of UICI stock over a period of 20
consecutive trading days prior to closing. The exchange ratio is described in
more detail inside the proxy statement. If such average price equals $23.625
(the closing stock price of UICI on October 22, 1999) you will receive .3393
shares of UICI common stock for each share of HealthPlan Services common stock
you own.

The merger cannot be completed unless holders of a majority of the outstanding
HealthPlan Services common shares vote to approve the merger. We have scheduled
a special meeting of HealthPlan Services stockholders to obtain this vote, and
stockholders who owned HealthPlan Services shares as of November 2, 1999 may
vote at this special meeting. If you vote your shares by proxy, you do not need
to attend the special meeting for your vote to be counted. The Board of
Directors of HealthPlan Services unanimously recommends that you vote "for"
approval of the merger at the special meeting.

Your Board of Directors believes that the merger will provide a strong platform
for growth in the healthcare administrative services industry. We also believe
that the merger will integrate two strong companies, creating more growth in
stockholder value than HealthPlan Services would realize as a stand-alone
company.

The attached proxy statement/prospectus gives you detailed information about the
meeting and the proposed merger. We encourage you to read this document
carefully. IN PARTICULAR, YOU SHOULD READ THE "RISK FACTORS" SECTION BEGINNING
ON PAGE 19 FOR A DESCRIPTION OF VARIOUS RISKS YOU SHOULD CONSIDER IN EVALUATING
THE PROPOSED MERGER.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.   WHAT IS THE PROPOSED TRANSACTION?

A    HealthPlan Services and UICI Acquisition Co. will combine in a merger.
     HealthPlan Services will survive in the merger as a wholly-owned subsidiary
     of UICI.

Q.   WHAT WILL I RECEIVE IN THE MERGER?

A.   You will be a holder of common stock of UICI after the merger. The number
     of shares of UICI common stock you will receive in the merger will depend
     upon the price of UICI common stock just prior to the closing of the
     merger.

     o    If the average of the volume weighted averages of the trading prices
          of UICI stock for a period of 20 consecutive trading days prior to the
          closing of the merger is higher than $33.00 per share, then for each
          share of HealthPlan Services common stock you own you will receive a
          fraction of a share of UICI common stock equal to $9.50 divided by (x)
          such average price of UICI stock minus (y) $3.00.

     o    If the average trading prices of UICI stock is less than or equal to
          $33.00 per share, but greater than $30.00 per share, then for each
          share of HealthPlan Services common stock you own you will receive
          .3167 of a share of UICI common stock.

     o    If the average trading prices of UICI stock is greater than or equal
          to $28.00 per share, but less than or equal to $30.00 per share, then
          for each share of HealthPlan Services common stock you own you will
          receive a fraction of a share of UICI common stock equal to $9.50
          divided by such average price of UICI stock.

     o    If the average trading prices of UICI stock is less than $28.00 per
          share, but greater than or equal to $23.00 per share, then for each
          share of HealthPlan Services common stock you own you will receive
          .3393 of a share of UICI common stock.

     o    If the average trading prices of UICI stock is less than $23.00 per
          share, but greater than or equal to $21.00 per share, then for each
          share of HealthPlan Services common stock you own you will receive a
          fraction of a share of UICI common stock equal to $9.50 divided by the
          sum of such average price plus $5.00.

     o    If the average trading prices of UICI stock is less than $21.00 per
          share, then for each share of HealthPlan Services common stock you own
          you will receive .3654 of a share of UICI common stock.

Q.   HOW WILL THE MERGER AFFECT MY STOCK DIVIDENDS?

A.   The dividend payment level of UICI after the merger will be determined by
     the board of directors of UICI. UICI does not currently pay a dividend and
     we anticipate that UICI will continue its current policy of not paying
     dividends following the merger.

Q.   WHAT DO I NEED TO DO TO GET MY SHARES OF UICI?

A.   After the merger is completed, UICI will send HealthPlan Services
     stockholders written instructions for exchanging their shares for shares of
     UICI. If you hold HealthPlan Services shares in certificate form, you
     should not send in your share certificates now.

Q.   CAN THE VALUE OF THE TRANSACTION CHANGE BETWEEN NOW AND THE TIME THE MERGER
     IS COMPLETED?

A.   Yes. As described above, the number and value of UICI shares that you will
     receive in the merger is dependent on the market value for UICI stock prior
     to the closing. Consequently, the value you receive will fluctuate based on
     such market value of UICI stock right up to the time of closing.

Q.   WHAT ARE MY TAX CONSEQUENCES AS A RESULT OF THE MERGER?

A.   The merger is structured so that each of UICI and HealthPlan Services will
     obtain an opinion of legal counsel that you will not recognize any gain or
     loss in exchanging your HealthPlan Services shares for common shares of
     UICI (except with respect to cash that you receive instead of any
     fractional share interest in UICI's common shares). Your tax basis in the
     common shares of UICI received in exchange for your HealthPlan Services
     shares will be the same as your tax basis in your exchanged HealthPlan
     Services shares, less an amount that you must allocate to cash that you
     receive instead of any fractional share interest.

     For more detail, see page 44 of this proxy statement/prospectus.

Q.   WHO IS SOLICITING MY VOTE?

A.   The Board of Directors of HealthPlan Services is soliciting your vote.

Q.   HOW DO I VOTE?

A.   You may vote by indicating on the enclosed proxy form how you want to vote,
     and signing and mailing the proxy form in the enclosed prepaid return
     envelope. Please vote as soon as possible to ensure that your shares are
     represented at the special meeting.

                                      -2-
<PAGE>

Q.   WHAT VOTE IS REQUIRED TO APPROVE THE MERGER?

A.   The merger must be approved by a majority of the outstanding HealthPlan
     Services common shares.

Q.   IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
     SHARES FOR ME?

A.   Your broker will vote your shares only if you provide your broker
     instructions on how to vote. You should follow the directions provided by
     your broker regarding how to instruct your broker to vote your shares.
     Without instructions, your shares will not be voted, which will have the
     same effect as voting against the merger.

Q.   CAN I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED PROXY?

A.   Yes. You can change your vote at any time before we vote your proxy at the
     special meeting in one of three ways. First, you can send a written notice
     stating that you would like to revoke your proxy to the Secretary at the
     address below. Second, you can complete a new proxy form and send it to the
     Secretary, and the new proxy form will automatically replace any earlier
     proxy form you returned. Third, you can attend, and vote in person at, the
     special meeting.

     You should send any written notice or new proxy to the Secretary of
     HealthPlan Services at the following address: Phillip S. Dingle, Secretary,
     HealthPlan Services Corporation, 3501 Frontage Road, Tampa, Florida 33607,
     Tel.: (813) 289-1000.

Q.   DO I HAVE THE RIGHT TO DISSENT?

A.   You do not have a right to dissent under Delaware law in connection with
     the proposed merger.

Q.   WHEN DO YOU HOPE TO COMPLETE THE MERGER?

A.   We hope to complete the merger shortly after the special meeting. Closing
     of the merger is subject to stockholder approval at this meeting and
     completion of federal antitrust clearance. We expect that we will have
     completed our antitrust review by November 15, 1999.

Q.   WILL MY RIGHTS AS A STOCKHOLDER CHANGE AS A RESULT OF THE MERGER?

A.   Currently, the rights of HealthPlan Services stockholders are governed by
     Delaware law and HealthPlan Services' certificate of incorporation and
     bylaws. After the merger, Delaware law will continue to govern, but UICI's
     certificate of incorporation and bylaws will govern your rights as a
     stockholder of UICI. For a summary of material differences between the
     rights of HealthPlan Services

                                      -3-
<PAGE>

     stockholders and the rights they will have as stockholders of UICI, see
     page 70 of this proxy statement/prospectus.

Q.   WHAT BENEFITS WILL I RECEIVE FROM BECOMING A UICI STOCKHOLDER?

A.   The Board of Directors of HealthPlan Services believes that, as a UICI
     stockholder, you will have the opportunity to realize potential benefits
     associated with a larger company, including additional capital resources
     and enhanced access to technology solutions.

Q.   WHERE CAN I FIND MORE INFORMATION ABOUT UICI AND HEALTHPLAN SERVICES?

A.   You can find more information about UICI and HealthPlan Services from
     various sources described under "WHERE YOU CAN FIND MORE INFORMATION" on

THE HEALTHPLAN SERVICES CORPORATION SPECIAL MEETING (SEE PAGE 23)

     The special meeting of HealthPlan Services stockholders will be held at
the offices of HealthPlan Services, 3501 Frontage Road, Tampa, Florida 33607, on
December 8, 1999, at 10:00 a.m., local time.

     At the special meeting, you will be asked to vote on a proposal to approve
the merger agreement among UICI, UICI Acquisition Co. and HealthPlan Services
and the merger of UICI Acquisition Co. and HealthPlan Services described in the
merger agreement. Approval of the merger agreement and the merger requires the
favorable vote of the holders of a majority of the outstanding HealthPlan
Services common shares.

           You can vote at the special meeting of HealthPlan Services
stockholders if you owned HealthPlan Services common shares at the close of
business on the record date, November 2, 1999. As of __________, 1999, directors
and executive officers of HealthPlan Services and their affiliates beneficially
owned approximately _______% of the outstanding HealthPlan Services common
shares. Automatic Data Processing, Inc., Shinnston Enterprises Inc., Elm Grove
Associates and James K. Murray, Jr., William L. Bennett and Robert R. Parker
(officers and directors of HealthPlan Services) have entered

                                      -7-
<PAGE>

into voting agreements with UICI. Under the terms of the voting agreements, the
parties agreed to vote their shares in favor of the merger. Approximately 17% of
HealthPlan Services' common shares are covered by these voting agreements.

     IF YOU DO NOT VOTE YOUR SHARES, THE EFFECT WILL BE A VOTE AGAINST THE
MERGER AGREEMENT AND THE MERGER.

     THE MERGER AND THE MERGER AGREEMENT (SEE PAGES 25 AND 48)

     In the proposed merger, UICI Acquisition Co. will merge into HealthPlan
Services. As a result of the merger, HealthPlan Services will become a
wholly-owned subsidiary of UICI. The merger agreement is the legal document that
governs the merger. The merger agreement is attached as Appendix A to this proxy
statement/prospectus, and we encourage you to read it carefully.

THE HEALTHPLAN SERVICES OPTION AGREEMENT (SEE PAGE 60)

     Concurrently with entering into the merger agreement, HealthPlan Services
granted a stock option to UICI. This stock option entitles UICI to purchase up
to 1,500,000 shares of HealthPlan Services common stock at a price of $7.375 per
share if specified conditions are met. These conditions are described in detail
in "THE MERGER AGREEMENT AND RELATED AGREEMENTS--OPTION AGREEMENT" on page 60
and "THE MERGER AGREEMENT ANd RELATED AGREEMENTS--TERMINATION AND TERMINATION
FEE" on page 57. We also have attached a copy of the option agreement to this
proxy statement/prospectus as Appendix B. This option agreement is intended to
increase the likelihood that the merger will be completed. It also may have the
effect of discouraging competing offers for HealthPlan Services.

OUR REASONS FOR THE MERGER (SEE PAGE 31)

     The HealthPlan Services Board of Directors believes that the merger will
provide opportunities to achieve benefits for its stockholders and customers
that would not be available in the absence of a business combination with UICI.
The complementary combination of HealthPlan Services' technology and the
technology of UICI's Insurdata division should enable HealthPlan Services to
compete more effectively in the changing healthcare climate. The HealthPlan
Services Board has had growing concern regarding whether HealthPlan Services has
sufficient and predictable revenue to generate required efficiencies in its
business. The HealthPlan Services Board assessed HealthPlan Services' strategic
alternatives and concluded that the terms of the merger agreement provided the
best means for you to maximize the value of your holdings. The Board also
determined that it was unlikely that any other viable acquirors were interested
in negotiating and consummating an acquisition transaction within a reasonable
period of time. The HealthPlan Services Board believes that the merger will
result in a strong combined entity with complementary businesses, corporate
goals and management philosophies and the financial resources necessary to
complete and pursue growth opportunities.

                                      -8-
<PAGE>

OUR RECOMMENDATIONS TO STOCKHOLDERS (SEE PAGE 33)

     The Board of Directors of HealthPlan Services recommends that stockholders
vote "FOR" the proposal to approve the merger agreement and the merger.

FAIRNESS OPINION (SEE PAGE 34)

     HealthPlan Services' financial advisor, Bear, Stearns & Co. Inc., has given
a written opinion to HealthPlan Services' Board of Directors that, as of October
5, 1999, the exchange ratio was fair from a financial point of view to holders
of HealthPlan Services common shares. This opinion is not intended to be a
recommendation to any HealthPlan Services stockholder as to how to vote. We have
attached a copy of Bear, Stearns & Co.'s opinion as Appendix C to this proxy
statement/prospectus. HealthPlan Services stockholders should read this opinion
in its entirety to fully understand it.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 44)

     It is a condition to the merger that HealthPlan Services and UICI each
receive a tax opinion that the merger qualifies as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code of 1986. This means that,
for U.S. federal income tax purposes, HealthPlan Services stockholders who
exchange their HealthPlan Services common shares solely for common shares of
UICI in the merger generally will recognize no gain or loss (except with respect
to cash received instead of any fractional share interest in UICI's common
shares).

     Because of the complexity of the tax laws and the individual nature of the
tax consequences of the merger, however, we recommend that you consult a tax
advisor concerning the applicable U.S. federal, state and local income tax
consequences of the merger.

BOARD OF DIRECTORS AND MANAGEMENT OF HEALTHPLAN SERVICES AFTER THE MERGER (SEE
PAGE 47)

     When we complete the merger, James K. Murray, Jr., currently the Chairman
of the HealthPlan Services Board, will become a member of the UICI board. The
Board of Directors of HealthPlan Services, which will be a wholly-owned
subsidiary of UICI following the merger, will consist of Gregory T. Mutz
(President and Chief Executive Officer of UICI), Steven K. Arnold (Vice
President of UICI), Glenn W. Reed (Executive Vice President and General Counsel
of UICI), William L. Bennett (currently Vice Chairman of HealthPlan Services)
and Phillip S. Dingle (currently Executive Vice President and Chief Financial
Officer of HealthPlan Services). It is expected that Steven K. Arnold, currently
head of UICI's student health insurance division, will become President and
Chief Executive Officer at HealthPlan Services. Steven V. Huslander, George E.
Lucco, Jeffrey W. Bak and Jeffrey Markle, currently officers of HealthPlan
Services, are expected to enter into employment agreements with HealthPlan

                                      -9-
<PAGE>

Services prior to the effective time of the merger, and it is expected that they
will all assume similar positions with HealthPlan Services following the merger.
Phillip S. Dingle is expected to enter into an employment agreement with UICI,
and it is expected that he will become the Chief Financial Officer of UICI
following the merger.

INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGER (SEE PAGE 47)

     Certain members of HealthPlan Services management and Board of Directors
have interests in the merger that may conflict with those of the other
stockholders. The HealthPlan Services Board of Directors was aware of these
interests and considered them when they approved the merger agreement and the
merger.

ACCOUNTING TREATMENT (SEE PAGE 46)

     We expect the merger to qualify as a "purchase" for accounting purposes.
Purchase accounting requires UICI to determine the purchase price based on the
consideration paid in the acquisition. The fair value of the acquired net
tangible assets is recorded by UICI as of the date on which the acquisition is
consummated. The excess of the purchase price over net tangible assets acquired
is required to be assigned among identifiable intangible assets based on fair
value. The amounts recorded for intangible assets and goodwill are required to
be amortized by systematic charges to income over the estimated periods of
benefit and estimated useful lives.

REGULATORY APPROVALS (SEE PAGE 46)

     In order to complete the merger, we must make a pre-merger notification
filing under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and we
cannot complete the merger until the specified Hart-Scott-Rodino waiting period
requirements have been satisfied.

COMPLETION OF THE MERGER (SEE PAGE 55)

           Before we can complete the merger, we must satisfy a number of
     conditions. These include:

     o    HealthPlan Services stockholders approving the merger agreement and
          the merger;

     o    obtaining the regulatory approval discussed above;

     o    obtaining all required governmental consents;

     o    obtaining authorization from the New York Stock Exchange to list the
          shares of UICI common stock to be delivered in the merger;

                                      -10-
<PAGE>


     o    each of HealthPlan Services and UICI obtaining an opinion from their
          respective tax counsel that the merger will constitute a "tax-free"
          reorganization for federal income tax purposes;

     o    the absence of any event, development or change of circumstance which
          would be likely to have a material adverse effect on UICI or
          HealthPlan Services.

     The merger will occur as soon as practicable after all of the conditions in
the merger agreement are satisfied.

TERMINATION AND TERMINATION FEES (SEE PAGE 57)

     The companies may agree in writing to terminate the merger agreement at any
time without completing the merger, even if stockholders of HealthPlan Services
have approved it.

     In addition, the merger agreement may be terminated:

     o    by either company, if the merger is not completed by March 31, 2000;

     o    by either company, if the HealthPlan Services stockholders do not
          approve the merger agreement and the merger;

     o    by either company, if the HealthPlan Services Board of Directors
          determines to accept a transaction with another entity after having
          reasonably concluded that the alternative transaction is more
          favorable to HealthPlan Services stockholders than the merger and that
          the entity proposing the transaction can adequately finance the
          transaction, and after having determined that its fiduciary duties
          require the board to reconsider its commitment to UICI;

     o    by UICI if the bank providing its financing commitment fails to fund
          its loans because of a material adverse change in the financial
          markets;

     o    by UICI, if the HealthPlan Services Board of Directors fails to
          recommend approval, withdraws or adversely modifies its recommendation
          of the merger to HealthPlan Services stockholders or approves or
          recommends an alternative transaction.

     The merger agreement provides for the payment of termination fees and
expenses in certain cases. For example, if the merger agreement is terminated
under specified circumstances involving an alternative transaction for
HealthPlan Services, HealthPlan Services must pay UICI a termination fee of $5
million. In addition, under the option agreement described above, UICI may
exercise the option to purchase 1,500,000 shares of HealthPlan Services common
stock if and when the merger agreement is terminated and a termination fee is
payable by HealthPlan Services.

                                      -11-
<PAGE>

     Whether or not the merger is completed, HealthPlan Services and UICI will
each pay their own fees and expenses, except that HealthPlan Services and UICI
will divide evenly the costs and expenses incurred in printing and mailing this
document, the fees that have been paid to the Securities and Exchange Commission
in connection with the merger and the fees that have been paid in connection
with the filings under the Hart-Scott-Rodino Antitrust Improvements Act.

APPRAISAL RIGHTS FOR DISSENTING STOCKHOLDERS

     Under Delaware law, you will not have any appraisal or dissenters' rights
in connection with the merger.

UNAUDITED SELECTED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

     In the table below, we provide you with unaudited selected pro forma
combined condensed financial information for UICI as if the merger had been
completed on January 1, 1998 for income statement purposes and on June 30, 1999
for balance sheet purposes. The information is based on adjustments to the
historical consolidated financial statements of UICI and HealthPlan Services to
give effect to the merger using the purchase method of accounting for business
combinations.

     It is important that when you read this unaudited selected pro forma
combined financial information, you read along with it the separate historical
financial statements and accompanying notes of UICI and of HealthPlan Services,
which are incorporated by reference in this proxy statement/prospectus. See
"WHERE YOU CAN FIND MORE INFORMATION" on page 77 of this proxy
statement/prospectus. It is also important that you read the unaudited pro forma
combined financial information and accompanying discussion and notes that are
included in this proxy statement/prospectus under "UNAUDITED PRO FORMA COMBINED
FINANCIAL INFORMATION" beginning on page 60. You should not rely on the
unaudited combined pro forma financial information as an indication of the
results of operations or financial position that would have been achieved if the
merger had taken place earlier or as an indication of the results of operations
or financial position of UICI that will be achieved after the completion of the
merger.

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     This proxy statement/prospectus contains forward-looking statements within
the meaning of the Private Securities Litigation Reform Act of 1995 with respect
to the financial condition, results of operations, cash flows, dividends,
financing plans, business strategies, operating efficiencies or synergies,
budgets, capital and other expenditures, competitive positions, growth
opportunities for existing products, benefits from new technology, plans and
objectives of management, markets for stock of UICI and HealthPlan Services and
other matters. Statements in this document that are not historical facts are
hereby identified as "forward-looking statements" for the purpose of the safe
harbor provided by Section 21E of the Securities Exchange Act of 1934 and
Section 27A of the Securities Act of 1933. Such forward-looking statements,
including, without limitation, those relating to the future business prospects,
revenues, working capital, liquidity, capital needs, interest costs and income,
in each case relating to UICI or HealthPlan Services wherever they occur in this
proxy statement/prospectus, are necessarily estimates reflecting the best
judgment of the senior managements of UICI and HealthPlan Services and involve a
number of risks and uncertainties that could cause actual results to differ
materially from those suggested by the forward-looking statements. Such
forward-looking statements should, therefore, be considered in light of various
important factors, including those set forth in this proxy statement/prospectus.
Important factors that could cause actual results to differ materially from
estimates or projections contained in the forward-looking statements include
without limitation:

     o    changes in general economic conditions, including the performance of
          financial markets and interest rates;

     o    competitive, regulatory or tax changes that affect the cost of or
          demand for products;

     o    ability to attract and retain key management personnel;

     o    health care reform, ability to predict and effectively manage claims
          related to health care costs;

     o    loss of contracts and inability to find new clients;

     o    reliance on key management and adequacy of claim liabilities and the
          ability of the companies and third party vendors to modify computer
          systems for the Year 2000 data conversion in a timely manner;

     o    the future results of UICI's credit card segment could be adversely
          affected by the possibility of future economic downturns, which might
          have the effect of causing an increase in credit losses or changes in
          regulations for credit cards or credit card national banks;

                                      -18-
<PAGE>

     o    changes in the Higher Education Act or other relevant federal or state
          laws, rules and regulations and the programs implemented thereunder
          may adversely impact UICI's education credit market;

     o    existing legislation and future measures by the federal government may
          adversely affect the amount and nature of federal financial assistance
          available with respect to loans made through the U.S. Department of
          Education;

     o    the level of competition currently in existence in the secondary
          market for loans made under the Federal Loan Programs could be
          reduced, resulting in fewer potential buyers of the Federal Loans and
          lower prices available in the secondary market for those loans; or

     o    unexpected costs, delays or difficulties related to the integration of
          HealthPlan Services' and UICI's businesses.

     The words "estimate," "project," "intend," "expect," "believe" and similar
expressions are intended to identify forward-looking statements. These
forward-looking statements are found at various places throughout this proxy
statement/prospectus and the other documents incorporated herein by reference,
including, but not limited to, the March 31, 1999 and June 30, 1999 Quarterly
Reports on Form 10-Q and the December 31, 1998 Annual Report on Form 10-K of
UICI (including any amendments thereto), and the March 31, 1999 and June 30,
1999 Quarterly Reports on Form 10-Q and the December 31, 1998 Annual Report on
Form 10-K of HealthPlan Services (including any amendments thereto). Readers are
cautioned not to place undue reliance on these forward-looking statements, which
speak only as of the date thereof and which are expectations which may not prove
to be correct due to reasons beyond the control of UICI or HealthPlan Services.
Neither UICI nor HealthPlan Services undertakes any obligation to publicly
release any revisions to these forward-looking statements to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.

                                  RISK FACTORS

     In addition to the other information included and incorporated by reference
in this proxy statement/prospectus, you should carefully read and consider the
following factors in evaluating the proposals to be voted on at the special
meeting.

     WE CANNOT ASSURE YOU THAT OUR TWO COMPANIES WILL BE SUCCESSFULLY
INTEGRATED.

     After the merger, UICI will need to integrate the operations, employees and
information systems of the two companies. Failure to successfully integrate our
operations may have a material adverse effect on our business, financial
condition or results of operations. Integrating two companies like UICI and
HealthPlan Services involves a number of risks, including:

     o    the diversion of management's attention away from ongoing operations;

                                      -19-
<PAGE>

     o    difficulties in the combining of operations and systems;

     o    difficulties in the assimilation and retention of employees;

     o    challenges associated with combining and integrating differing
          technology platforms;

     o    challenges in keeping customers; and

     o    potential adverse short-term effects on operating results.

     UICI has estimated that it will be able to achieve annual cost savings of
approximately $6.0 million in 2001, increasing to approximately $9.0 million
annually by 2003, as a result of the combination of the operations of the two
companies. However, we may not be able to achieve these cost savings and other
size and scale-related benefits because of difficulties in integrating
operations.

     THE MERGER MAY CAUSE US TO LOSE SOME OF OUR IMPORTANT THIRD-PARTY
ADMINISTRATION CONTRACTS.

     A major part of HealthPlan Services' business is the provision of marketing
and administration services for insurance companies, managed care organizations,
and organizations with self-funded health care plans. Most of HealthPlan
Services' contracts with self-funded clients have one year renewable terms and
are terminable by the client by providing written notice either sixty or ninety
days prior to the renewal date. HealthPlan Services' insurance company and
managed care contracts generally have terms ranging in length from twelve to
forty-eight months, but many of these agreements are terminable without cause by
the customer upon advance notice of between six months and one year.
Furthermore, several of HealthPlan Services' agreements, including its
agreements with New England Life Insurance Company and Celtic Life Insurance
Company, are terminable upon a change in control of HealthPlan Services.
Accordingly, we cannot assure you that these contracts will remain in effect on
the same terms as currently exist. The loss of a substantial amount of this
business, or the renegotiation of such business on less favorable terms, may
have a material adverse effect on the combined company's business, financial
condition, or results of operations.

     THE ABILITY TO REALIZE COST SAVINGS FOLLOWING THE MERGER WILL DEPEND IN
LARGE PART UPON THE SUCCESSFUL IMPLEMENTATION AND INTEGRATION OF UICI'S
TECHNOLOGY SOLUTIONS IN HEALTHPLAN SERVICES' BUSINESS.

     Failure to fully realize the expected cost savings following the merger
could have an adverse effect on the business and results of HealthPlan Services.
Achieving cost savings will be a critical component of UICI's and HealthPlan
Services' strategy following the merger. The companies currently expect to
utilize proprietary Internet-based software solutions developed by UICI's
Insurdata business unit for HealthPlan

                                      -20-
<PAGE>

Services' enrollment, billing and collection, and claims administration
services. If successfully applied to HealthPlan Services' operations in a timely
manner, UICI believes that this technology may serve to reduce HealthPlan
Services' cost of providing services, which will, in turn, make the services
provided by HealthPlan Services more attractive to potential customers and
clients. There can be no assurance, however, that UICI's proprietary technology
can be integrated into the business of HealthPlan Services in a timely or
cost-efficient manner.

HEALTHPLAN SERVICES' EARNINGS PER SHARE DURING THE THIRD QUARTER OF 1999 WILL BE
LOWER THAN ANALYSTS' ESTIMATES.

     In a press release issued by HealthPlan Services on October 8, 1999,
HealthPlan Services announced that third quarter earnings per share will be
lower than analysts' estimates for such period. The management of HealthPlan
Services expects to establish a reserve for claims asserted during the third
quarter in the approximate amount of between $5.0 and $6.0 million. Although
management currently expects that this reserve will be sufficient to cover all
such outstanding claims, there can be no assurance that ultimate losses from
these claims will be less than or equal to the reserve. In addition, HealthPlan
Services' management expects to take a restructuring charge of up to $3 million
during the fourth quarter of 1999. The charge is aimed at reducing operating
expenses primarily in HealthPlan Services' large group business.

                                  THE COMPANIES

     FOR YOUR CONVENIENCE, WE HAVE INCLUDED ON PAGE 79 A LIST OF CERTAIN DEFINED
TERMS USED IN THIS PROXY STATEMENT/PROSPECTUS.

HEALTHPLAN SERVICES CORPORATION

     HealthPlan Services is a leading managed health care services company,
providing distribution, enrollment, billing and collection, and claims
administration services for health care payors and providers. HealthPlan
Services' customers include insurance companies, health maintenance
organizations ("HMOs") and other managed care organizations, and organizations
with self-funded health care plans. HealthPlan Services provides these services
to approximately 140,000 groups covering over 3 million members in the United
States. HealthPlan Services functions solely as a service provider generating
fee-based income and does not assume any underwriting risk. In May 1998,
HealthPlan Services acquired National Preferred Provider Network, Inc. ("NPPN"),
a preferred provider organization network consisting of over 450,000 physician
offices, 4,000 hospitals and 50,000 ancillary care provider locations in all 50
states and the District of Columbia. Except for its NPPN subsidiary, the revenue
of which is not significant for reporting purposes, HealthPlan Services operates
in one business segment.

     In December 1998, HealthPlan Services introduced an interactive electronic
Internet site through which certain plan transactions can be performed
electronically. The site, which is accessible through HealthPlan Services' home
page (www.healthplan.com), enhances HealthPlan Services' capabilities in all
aspects of its services.

     HealthPlan Services was incorporated in 1994 under the laws of Delaware and
has its principal executive offices at 3501 Frontage Road, Tampa, Florida 33607
(telephone number 813-289-1000). Internet users can obtain information about
HealthPlan Services and its services at http://www.healthplan.com

UICI

     UICI is a diversified financial services company that offers insurance and
financial services to niche consumer and institutional markets. UICI also
provides

                                      -21-
<PAGE>

technology and outsourcing solutions to the insurance and healthcare services
communities.

     UICI issues health insurance policies to the self-employed and student
markets. For the self-employed market, which includes self-employed individuals
and individuals who work for small businesses with five or fewer employees, UICI
offers a range of health insurance products. Catastrophic hospital and basic
hospital-medical expense plans are designed to accommodate individual needs and
include both choice-of-doctor plans and managed care options such as a preferred
provider organization ("PPO") plan as well as other coverage modifications. UICI
markets these higher deductible products through "dedicated" agency sales forces
that primarily sell UICI's products. For the student market, UICI offers
tailored insurance programs that generally provide single school year coverage
to individual students, primarily at universities, but also at public and
private schools for students in kindergarten through grade 12. In this market,
UICI sells its products primarily through in-house account executives that focus
on colleges and universities on a national basis. UICI also issues life and
annuity insurance products to selected niche markets, and UICI acquires blocks
of life insurance and annuity policies from other insurers on an opportunistic
basis. The life and annuity insurance policies issued by UICI are marketed
through a dedicated agency sales force. During 1998 and the first six months of
1999, health insurance premiums were approximately $747 million and $351
million, respectively, representing 63% and 56% of UICI's total revenues in such
periods.

     UICI also provides underwriting, claims management and claims
administrative services to third party insurance carriers (primarily to Aegon
USA, Inc. related to products coinsured by UICI), third party administrators,
Blue Cross/Blue Shield organizations and self-administered employer health care
plans.

     Through its wholly-owned subsidiary, United CreditServ, Inc., UICI assists
individuals with no, or troubled, credit in obtaining a nationally recognized
credit card. The credit cards are issued by United Credit National Bank, and
serviced by Specialized Card Services, Inc., each a wholly-owned subsidiary of
United CreditServ. United CreditServ also provides outsourcing and fulfillment
services to organizations that provide credit education materials to United
Credit National Bank's credit card applicants. During 1998 and the first six
months of 1999, revenues from United CreditServ were approximately $113.0
million and $100.0 million, respectively, representing 10% and 16% of UICI's
total revenues in such periods.

     UICI markets, originates, funds and services primarily Federally-guaranteed
student loans.

     UICI entered the student loan origination business in 1997, when it
acquired a controlling interest in Educational Finance Group, Inc. UICI seeks to
provide solutions for college and graduate school students, their parents and
the educational institutions they attend. UICI offers a package of student
loans, student loan servicing and student insurance, and, following its
acquisition in July 1999 of Academic Management Services, Inc., UICI became a
leading provider of student tuition installment plans. At June 30,

                                      -22-
<PAGE>

1999, UICI had approximately $950.0 million aggregate principal amount of
student loans outstanding, of which approximately 90% were Federally guaranteed.

     UICI's Insurdata subsidiary develops comprehensive technology solutions and
provides related outsourcing services to the administration segment of the
healthcare industry. Insurdata's services include proprietary workflow and
Internet-enabled business applications that enhance transaction processing and
promote the flow of information among constituent users, including healthcare
providers, payors, managed care and case management organizations, reinsurance
carriers, agents, preferred provider organizations, medical and dental claim
review staffs, employers and employees. In addition, Insurdata offers systems
integration, technology management and data capture services.

     Through its National Motor Club unit, UICI also markets and provides over
450,000 members with benefits such as road and towing assistance, trip routing,
emergency travel assistance, and accident related indemnity benefits.

     UICI was incorporated in 1984 under the laws of Delaware and has its
principal executive offices at 4001 McEwen, Suite 200, Dallas, Texas 75244
(telephone number 972-392-6700). Internet users can obtain information about
UICI and its services at http://www.uici.net.

holders of record. The presence, in person or by a valid proxy, of the holders
of a majority of the outstanding HPS Common Shares entitled to vote at the
special meeting is necessary to constitute a quorum at the special meeting.

     Holders of HPS Common Shares represented in person or by proxy will be
counted for the purposes of determining whether a quorum is present at the
special meeting. Broker non-votes will be treated as HPS Common Shares that are
present and entitled to vote at the special meeting for purposes of determining
whether a quorum exists and will have the same effect as votes against approval
of the merger agreement and the merger.

VOTING AND REVOCATION OF PROXIES

     All HPS Common Shares that are entitled to vote and are represented at the
special meeting by valid proxies received before or at the special meeting, and
not revoked, will be voted at the special meeting in accordance with the
instructions indicated on such proxies. If no instructions are indicated (other
than in the case of broker non-votes), such proxies will be voted in favor of
the proposal to approve the merger agreement and the merger. With respect to any
other business that may properly come before the special meeting and be
submitted to a vote of stockholders, proxies received by the Board of Directors
will be voted in accordance with the judgment of the designated proxy holders.
Under the rules of the New York Stock Exchange, HPS Common Shares held by a
broker or nominee may not be voted at the special meeting without instructions
to do so from the beneficial owner(s).

     The Board does not know of any matters other than the merger proposal that
are to come before the special meeting. If any other matters are properly
presented at the special meeting for consideration, including, among other
things, consideration of a motion to adjourn the special meeting to another time
and/or place (including, without limitation, for the purposes of soliciting
additional proxies or allowing additional time for

                                      -24-
<PAGE>

the satisfaction of conditions to the merger), the persons named in the enclosed
proxy form and acting thereunder generally will have discretion to vote on these
matters in accordance with their judgment if so authorized by instructions given
on such proxy. Notwithstanding the foregoing, proxies voting against a specific
proposal may not be used by the persons named in the proxies to vote for
adjournment of the special meeting for the purpose of providing HealthPlan
Services additional time to solicit votes to approve that proposal.

     Any proxy given to HealthPlan Services pursuant to this solicitation may be
revoked by the person giving it at any time before it is voted. Proxies may be
revoked by (1) filing with the Secretary of HealthPlan Services, at or before
the taking of the vote at the special meeting, a written notice of revocation
bearing a later date than the proxy, (2) duly executing a later-dated proxy
relating to the same HPS Common Shares and delivering it to the Secretary of
HealthPlan Services before the taking of the vote at the special meeting, or (3)
attending the special meeting and voting in person (although attendance at the
special meeting will not in and of itself constitute a revocation of a proxy).

     ANY WRITTEN NOTICE OF REVOCATION OR SUBSEQUENT PROXY SHOULD BE SENT TO
     HEALTHPLAN SERVICES CORPORATION, 3501 FRONTAGE ROAD, TAMPA, FLORIDA 33607,
     ATTENTION: CORPORATE SECRETARY, OR BE HAND DELIVERED TO THE SECRETARY OF
     HEALTHPLAN SERVICES CORPORATION AT OR BEFORE THE TAKING OF THE VOTE AT THE
     SPECIAL MEETING.

           All expenses of our solicitation of proxies for the special meeting
will be borne by HealthPlan Services. In addition to solicitation by use of the
mails, proxies may be solicited from stockholders by directors, officers and
employees of HealthPlan Services in person or by telephone, telegram or other
     means of communication. These directors, officers and employees will not be
additionally compensated, but may be reimbursed for reasonable out-of-pocket
expenses in connection with the solicitation. We have retained First Union
National Bank, a proxy solicitation firm, to assist us in the solicitation of
proxies for the special meeting at a cost of approximately $1,200 plus
reimbursement of reasonable out-of-pocket expenses. In addition, we will make
arrangements with brokerage houses, custodians, nominees and fiduciaries for
forwarding of proxy solicitation materials to beneficial owners of HPS Common
Shares held of record by these brokerage houses, custodians, nominees and
fiduciaries, and we will reimburse these brokerage houses, custodians, nominees
and fiduciaries for their reasonable expenses.

                                   THE MERGER

     We are furnishing this proxy statement/prospectus to you in connection with
the proposed merger between HealthPlan Services and a wholly-owned subsidiary of
UICI because you are a stockholder of HealthPlan Services. If completed, the
merger will be carried out as provided in the merger agreement, a copy of which
is attached as Appendix A to this proxy statement/prospectus.

                                      -25-
<PAGE>

     The merger agreement provides that the merger will be accomplished by
merging a new UICI subsidiary (which we refer to as New UICI Sub) into
HealthPlan Services. Following the merger, the Common Stock of HealthPlan
Services will be 100% owned by UICI.

     In the merger, each outstanding HPS Common Share will be converted into the
right to receive a fraction of a share of UICI common stock. The fraction will
be determined based on an exchange ratio that is, in turn, based on the average
of the volume weighted average trading prices of UICI stock for a period of 20
consecutive trading days ending on the third trading day immediately prior to
the effective date of the merger. The exchange ratio will be calculated as
follows:
<TABLE>
<CAPTION>

       PRICE RANGE OF UICI STOCK (PER SHARE)                         EXCHANGE RATIO
       -------------------------------------                         --------------

<S>   <C>                                               <C>
o     Greater than $33.00                               $9.50 /divided by/ (average price of UICI stock - $3.00)

o     Less than or equal to $33.00 and greater
      than $30.00                                       .3167

o     Less than or equal to $30.00, but greater
      than or equal to $28.00                           $9.50 /divided by/ (average price of UICI stock)

o     Less than $28.00, but greater than or equal
      to $23.00                                         .3393

o     Less than $23.00, but greater than or equal
      to $21.00                                         $9.50 /divided by/ (average price of UICI stock + $5.00)

o     Less than $21.00                                  .3654
</TABLE>

     In no event, however, will you receive a fractional share of UICI common
stock. Instead, if you would otherwise be entitled to receive a fractional share
of UICI stock, you will be paid an amount in cash equal to such fraction
multiplied by the volume-weighted average closing price for UICI common stock on
the New York Stock Exchange for the five trading days immediately preceding the
effective date of the merger.

BACKGROUND

     UICI, together with its subsidiaries, is a diversified financial services
company that offers insurance and financial services to niche consumer and
institutional markets. UICI also provides technology and outsourcing solutions
to the insurance and health services communities. UICI issues health insurance
policies to the self-employed and student markets; markets credit support
services to individuals with no, or troubled, credit experience and assists them
in obtaining a nationally recognized credit card; markets, originates, funds and
services primarily Federally guaranteed student loans; and provides motor club
services to motorists, including road and towing assistance, trip routing,
emergency travel assistance, and accident related indemnity benefits.

                                      -26-
<PAGE>

     Since its founding in 1984 primarily as a health insurer, UICI has
continuously sought ways to diversify and broaden its activities away from
traditional health insurance, or risk-based, product offerings. Since 1992 UICI
has furthered this objective by making the following acquisitions:

          o    In 1992, UICI formed its credit services division, which markets
               credit support services to individuals with no, or troubled,
               credit experience and assists such individuals in obtaining a
               nationally recognized credit card. UICI established a credit card
               service center in South Dakota in 1995, and, in February 1997,
               UICI successfully chartered a special-purpose national bank for
               the purpose of issuing the credit card accounts. In 1999, UICI
               reorganized this business under the "United CreditServ" name.

          o    In April 1996 UICI acquired the underwriting, claims management
               and administrative capabilities of AEGON USA, Inc. related to
               health insurance products coinsured by UICI.

          o    In 1995 UICI purchased 51% of Insurdata Incorporated. Insurdata
               develops comprehensive technology solutions and provides related
               outsourcing services to the administration segment of the
               healthcare industry. In addition, Insurdata offers systems
               integration, technology management and data capture services. In
               December 1996, UICI purchased the 49% of Insurdata that it did
               not already own and completed the transfer to Insurdata of UICI's
               insurance technology assets and technology-related personnel.

          o    UICI entered the student loan origination and servicing business
               in May 1997 through the formation of Educational Finance Group,
               and, in 1999 Educational Finance Group acquired Academic
               Management Services, Inc., a leading provider of tuition
               installment payment plans.

          o    In August 1997, UICI acquired National Motor Club of America,
               Inc., a provider of motor club services.

     Consistent with its diversification objectives, UICI was attracted to
HealthPlan Services' transaction-based business and the perceived opportunities
to apply technology solutions developed by UICI's Insurdata unit to the claims
administration and claims management businesses of HealthPlan Services. Because
UICI has itself been engaged in claims management and administration activities,
UICI believed that it was capable of evaluating the risks and opportunities
associated with HealthPlan Services' business.

     DISCUSSIONS BETWEEN HEALTHPLAN SERVICES AND UICI

     In July 1999, Gregory T. Mutz (President and Chief Executive Officer of
UICI) called James K. Murray, Jr. (Chairman and Chief Executive Officer of
HealthPlan Services) to inquire on an introductory basis whether Mr. Murray
might entertain discussions that might lead to a possible business combination
of UICI and HealthPlan Services. Mr. Murray indicated that he would be willing
to conduct such discussions. Unknown to Mr. Mutz, at the direction of the
HealthPlan Services' Board, HealthPlan Services had previously retained Bear,
Stearns & Co., Inc. in January 1999 to investigate ways to enhance stockholder
value, including the possible entry into a strategic business combination in
order to complement HealthPlan Services' core capabilities.

     On August 3, 1999, Mr. Mutz and Steven K. Arnold (UICI's Chief Executive
Officer, Student Insurance Division) met in Tampa with Mr. Murray and the
leaders of HealthPlan Services' small group, managed care and information
technology business units to discuss mutual business opportunities facing UICI
and HealthPlan Services. On August 26, 1999, Mr. Arnold met in Columbus, Ohio
with the head of HealthPlan Services' large group operations.

     On August 11, 1999, UICI and HealthPlan Services executed a confidentiality
agreement in connection with their continuing discussions. Also on August 11,
Dennis Maloney (President of UICI's Insurdata subsidiary), Mr. Arnold and other
representatives of Insurdata visited HealthPlan Services' office in Tampa to
meet with the head of HealthPlan Services information technology business unit
and to review and assess HealthPlan Services' technology resources. On August
31, representatives of HealthPlan Services visited Insurdata in Dallas to review
Insurdata's information technology capabilities.

     On September 2, 1999, Ronald L. Jensen (Chairman of UICI) and Mr. Murray
met in Tampa and discussed general business conditions in the healthcare
services industry. On September 3, 1999, Mr. Jensen, Mr. Mutz, Mr. Arnold and
Glenn W. Reed (Executive Vice President and General Counsel of UICI) met in
Tampa with Mr. Murray and other members of senior management of HealthPlan
Services. At this meeting, presentations were made by the business leaders of
HealthPlan Services' information technology, large group, small group and NPPN
managed care operations, and the perceived benefits associated with a possible
combination of UICI and HealthPlan Services were discussed. At the conclusion of
the meeting, Mr. Mutz informed Mr. Murray that UICI was prepared to proceed with
negotiations leading to a possible stock for stock acquisition by UICI of
HealthPlan Services in the range of $8.00 per HealthPlan Services share. Mr.
Murray requested that UICI management prepare a more detailed written proposal
with respect to a possible transaction for delivery to the HealthPlan Services
Board. In response to that request, on September 7, 1999, UICI delivered to
HealthPlan Services a preliminary written discussion draft of a summary of terms
outlining proposed terms of a tax-free, stock-for-stock merger transaction in
which HealthPlan Services stockholders would receive UICI stock in accordance
with an exchange ratio that is obtained by dividing $8.00 (the proposed
acquisition price of

                                      -28-
<PAGE>

HealthPlan Services common stock) by the average closing sale price of UICI
common stock during the ten consecutive trading days immediately preceding the
date of the merger agreement.

     Mr. Mutz, Mr. Arnold and Mr. Murray spoke periodically on the telephone
during the period September 7 to September 30 concerning the proposed
transaction.

     On September 23, 1999, UICI formally engaged Donaldson Lufkin & Jenrette
Securities Corporation to serve as UICI's financial advisor in connection with
the transaction. Donaldson Lufkin assisted UICI in preparing a financial model
of a proposed transaction and in performing other financial analyses.

     On September 15, 1999, Mr. Mutz spoke with a senior officer of Bank of
America, N.A., concerning UICI's need to secure additional bank or other
financing in order to complete the transaction. On September 17, 1999,
representatives of UICI met with representatives of Bank of America, N.A. to
discuss the possible transaction and to consider the possibility of increasing
UICI's existing $100 million credit facility to a $250 million facility, to
accommodate HealthPlan Services' existing debt and to provide additional growth
capital to UICI. Representatives of Bank of America expressed a willingness to
proceed with discussions.

     On September 22, 1999, Mr. Mutz and other representatives of UICI, Mr.
Murray and other representatives of HealthPlan Services, representatives of
Donaldson Lufkin and representatives of Bear Stearns met in Tampa to further
discuss the terms of a possible business combination transaction. At that
meeting, Mr. Mutz advised HealthPlan Services that UICI would be willing to
increase its offer to acquire HealthPlan Services by proposing an exchange ratio
that would be in the range of .3065 to .38, depending upon the closing sale
price of UICI common stock during the twenty consecutive trading days
immediately preceding the completion of the merger. UICI confirmed its offer in
a written summary of preliminary discussion terms delivered to Mr. Murray on
September 23.

     On September 23, 1999, the Board of HealthPlan Services met telephonically,
during which Mr. Murray advised the Board of the terms of UICI's offer and the
terms were discussed. The HealthPlan Services Board authorized management to
allow UICI to proceed with its more detailed due diligence inquiries, and UICI
and HealthPlan Services directed their respective legal counsel to prepare
drafts of definitive documentation with respect to a proposed stock-for-stock
merger transaction.

     During the week of September 27, 1999, representatives of UICI and Bank of
America conducted additional due diligence inquiries in Tampa, during which
non-public information concerning HealthPlan Services was shared with UICI and
Bank of America. A draft merger agreement was circulated, and negotiations
ensued concerning its terms.

                                      -29-
<PAGE>

     On September 30, 1999, UICI received a draft form of commitment from Bank
of America contemplating a $250 million unsecured credit facility. Negotiations
ensued between UICI and Bank of America concerning the terms of the proposed
facility and the commitment letter. On October 3, 1999, Mr. Mutz and Mr. Arnold
met with members of HealthPlan Services management in Tampa to conclude several
additional due diligence inquiries, including management's assessment of
HealthPlan Services' projected financial results of operations for the third and
fourth quarters of 1999 and the full year 2000.

     A special telephonic meeting of the UICI Board of Directors was held to
consider the proposed transaction on October 4, 1999. At the meeting, the terms
and conditions of the proposed transaction were reviewed in detail by UICI's
management and a representative of Gardner, Carton & Douglas (UICI's special
legal counsel). In addition, UICI's management described the potential benefits
and business rationale for the transaction. Representatives of Donaldson Lufkin
& Jenrette made a detailed financial presentation to the Board. Discussion and
questions from UICI Board members followed the presentations. Mr. Mutz advised
the Board that UICI had not completed its negotiations with Bank of America
concerning the terms of the financing commitment, and the Board directed Mr.
Mutz to complete those discussions and the negotiations of the proposed merger
agreement.

     A continuation of the Special Meeting of the UICI Board of Directors was
held telephonically on October 5 to consider and approve the proposed
transaction. At that meeting, Mr. Mutz advised the Board that the discussions
with respect to the Bank of America financing commitment had concluded to
management's satisfaction, and the terms and conditions of Bank of America's
commitment were summarized. Following further discussion, the UICI Board of
Directors unanimously adopted the merger agreement and approved the merger.

     A special telephonic meeting of the HealthPlan Services Board was held on
October 4, 1999 to discuss the merger agreement. In attendance at this meeting
were representatives of Bear Stearns and representatives of Fowler, White,
Gillen, Boggs, Villareal and Banker, P.A. (outside legal counsel to HealthPlan
Services). At this meeting, representatives of Bear Stearns reviewed the events
and discussions that led to the negotiations with UICI. In particular, Bear
Stearns recounted that, beginning in February 1999, Bear Stearns approached
certain parties on behalf of HealthPlan Services with regard to a potential
merger. Subject to non-disclosure agreements, these parties were given
non-public information about HealthPlan Services and an opportunity to meet with
the senior management of HealthPlan Services. From this process, seven parties
were identified by HealthPlan Services and Bear Stearns as "high probability"
candidates expressing an interest in a possible acquisition of HealthPlan
Services. They noted that the September 7, 1999 preliminary term sheet presented
by UICI was the culmination of this process. At the October 4 meeting, there was
also considerable discussion by the HealthPlan Services Board as to how the
exchange ratio should work, and the management noted that the pricing mechanism
was still being discussed. The Board

                                      -30-
<PAGE>

asked management to continue negotiations and scheduled a continuation of the
meeting for the following day.

     On October 5, 1999, the HealthPlan Services Board reconvened the meeting of
the previous day. At that meeting, management indicated that the exchange ratio
had been finalized and Bear Stearns had been given the updated information to
incorporate into their analysis. Management began the meeting by reviewing the
pricing terms, Bear Stearns then reviewed with the Board the material terms of
the merger and various information regarding UICI and HealthPlan Services,
including the basis of their fairness review and analysis. Representatives of
Fowler White commented upon the legal terms of the proposed agreement. Upon
conclusion of their report, Bear Stearns advised the Board of its opinion
concerning the fairness of the transaction to HealthPlan Services' stockholders.
See "HEALTHPLAN SERVICES CORPORATION'S REASONS FOR THE MERGER - OPINION OF BEAR
STEARNS." After deliberations about those and other aspects of the transaction,
including the potential advantages and disadvantages discussed below (see
"HEALTHPLAN SERVICES CORPORATION'S REASONS FOR THE MERGER; RECOMMENDATION OF THE
HEALTHPLAN SERVICES BOARD"), the HealthPlan Services Board members present at
the meeting voted unanimously to approve the merger agreement and merger
transaction and voted to recommend the same to the HealthPlan Services
stockholders.

     On the evening of October 5, 1999, the parties executed the merger
agreement and issued a joint press release announcing the execution of the
merger agreement.

HEALTHPLAN SERVICES CORPORATION'S REASONS FOR THE MERGER; RECOMMENDATION OF THE
HEALTHPLAN SERVICES BOARD

In determining to approve the merger, the management of HealthPlan Services and
the HealthPlan Services' Board considered a number of factors, including the
following:

     CHANGES IN THE HEALTH CARE INDUSTRY

     The health care industry is undergoing dramatic changes that will require
companies such as HealthPlan Services to have state-of-the-art technology and a
large volume of healthcare transactions in order to be successful. After
consulting with the management of HealthPlan Services, the Board concluded that
HealthPlan Services' technology and the technology of UICI's Insurdata division
are complementary and will enable HealthPlan Services' business to compete more
effectively in the changing healthcare climate. In addition, the HealthPlan
Services Board believes that UICI's insurance subsidiaries will provide a
greater volume of transactions that will help the business develop better
economies of scale and efficiencies.

     CONDITION OF HEALTHPLAN SERVICES

     The HealthPlan Services Board considered the prospects, results of
operations, and objectives of HealthPlan Services (as well as the risks involved
in achieving these objectives given the current economic and market conditions).
For the period 1997

                                      -31-
<PAGE>

through 1999, revenues for HealthPlan Services were essentially flat despite the
fact that HealthPlan Services made two acquisitions and continued to invest in
technological resources. While margins in 1999 were an improvement over 1998
margins, the HealthPlan Services Board and management has had growing concern
regarding whether HealthPlan Services has sufficient and predictable revenue to
generate required efficiencies in its business. It was also becoming apparent
that the technological changes created by the internet would require additional
resources to implement properly.

     UICI'S BUSINESS AND PROSPECTS

     The HealthPlan Services Board received and reviewed public and non-public
information regarding UICI and discussed UICI's prospects with Bear Stearns. The
HealthPlan Services Board believes that the merger will result in a strong
combined entity with (a) complementary businesses, corporate goals, and
management philosophies, (b) the financial resources necessary to complete and
pursue growth opportunities, and (c) access to technology solutions that have
the potential to lower the cost of providing services to customers and clients.

     STRATEGIC ALTERNATIVES

     The HealthPlan Services Board assessed HealthPlan Services' strategic
alternatives, including the alternative of remaining a publicly owned
independent company and the response by other companies to a possible business
combination with HealthPlan Services. They balanced the risks and benefits of
the merger against the risks and benefits of the other strategic alternatives
available to HealthPlan Services. Following extensive analysis and discussion
with its legal and financial advisors, the HealthPlan Services Board concluded
that the terms of the merger agreement provided the best means for the
HealthPlan Services stockholders to maximize the value of their holdings.

     OTHER POTENTIAL ACQUIRORS

     The HealthPlan Services Board considered, after consultation with
management, outside counsel, and Bear Stearns, the likelihood of the existence
of other viable acquirors on terms as favorable as those in the merger
agreement. Based on a review of the success of HealthPlan Services' and Bear
Stearns' efforts to seek and obtain bona fide acquisition offers during the
period prior to the commencement of negotiations with UICI, the HealthPlan
Services Board concluded that it was unlikely that any such other viable
acquirors were interested in negotiating and consummating an acquisition
transaction within a reasonable period of time.

     ANALYSIS OF KEY PROVISIONS OF MERGER AGREEMENT

     The HealthPlan Services Board analyzed the terms and conditions of the
merger agreement, including:

                                      -32-
<PAGE>

     (1)  the provisions requiring that the number of UICI shares to be issued
          to the HealthPlan Services stockholders in the merger be determined
          with respect to the trading price of UICI stock during the twenty
          consecutive trading days ending on the day which is three business
          days before the date the merger is consummated; and

     (2)  the right of HealthPlan Services to negotiate with, and provide
          information to, third parties and terminate the merger agreement in
          the event of an unsolicited alternative proposal if such action is
          required in the exercise of the fiduciary duties of the HealthPlan
          Services Board. If the Board terminates the merger because its
          fiduciary duties require it to do so or if the HealthPlan Services
          stockholders fail to approve the merger and within 18 months
          HealthPlan Services is acquired by another party, HealthPlan Services
          would be obligated to pay UICI a $5,000,000 termination fee.
          Additionally, the HealthPlan Services Board granted to UICI an option
          to purchase 1,500,000 shares of HealthPlan Services common stock. This
          option is exercisable if and only under the same circumstances that a
          termination fee would be payable. The HealthPlan Services Board did
          not believe that the existence of these termination fees and the
          option will preclude any third party from proposing an alternative
          transaction.

     OPINION OF BEAR STEARNS

     The HealthPlan Services Board considered the presentation of Bear Stearns
and its written opinion dated October 5, 1999, which provides that, based upon
and subject to the assumptions, limitations, and qualifications set forth in
such opinion, the exchange ratio is fair to the HealthPlan Services stockholders
from a financial point of view. The HealthPlan Services Board believes that the
analyses prepared and reviewed by Bear Stearns validate the fairness of the
exchange ratio from a financial point of view. For a summary of Bear Stearns'
opinion, including the assumptions made, matters considered, and limits of
review, see "THE MERGER-OPINION OF THE FINANCIAL ADVISOR TO THE HEALTHPLAN
SERVICES BOARD."

     TAX TREATMENT

     The HealthPlan Services board considered the fact that the merger is
designed to be tax free to the HealthPlan Services stockholders and that the
HealthPlan Services stockholders will retain the entire amount of their
investment in stock upon completion of the transaction without triggering any
tax liability (except to the extent that they receive cash for fractional
shares).

     MANAGEMENT'S RECOMMENDATION

     The HealthPlan Services Board received and reviewed presentations from, and
discussed the terms and conditions of the merger agreement with, executive
officers of HealthPlan Services and its financial and legal advisors. The
HealthPlan Services Board

                                      -33-
<PAGE>

considered management's and its financial advisors' views of recent trends in
HealthPlan Services' industry. However, in connection with its deliberations,
the HealthPlan Services Board was also aware of the potential benefits to be
received in the merger by members of HealthPlan Services' senior management, as
described under "THE MERGER - INTERESTS OF CERTAIN PERSONS IN THE MERGER."

     The above discussion of the information and factors considered by the
HealthPlan Services Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the merger,
the HealthPlan Services Board did not find it practicable to, and did not,
quantify or otherwise assign relative weights to the specific factors considered
in reaching its determination.

     THE HEALTHPLAN SERVICES BOARD UNANIMOUSLY RECOMMENDS THAT THE HEALTHPLAN
SERVICES STOCKHOLDERS VOTE TO APPROVE AND ADOPT THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY.

     OPINION OF THE FINANCIAL ADVISOR TO THE HEALTHPLAN SERVICES BOARD

     At the October 5, 1999 meeting of the HealthPlan Services Board, Bear
Stearns delivered its oral opinion (subsequently confirmed in writing) that the
exchange ratio to be provided for in the merger is fair, from a financial point
of view, to the stockholders of HealthPlan Services.

     THE FULL TEXT OF THE BEAR STEARNS OPINION, WHICH SETS FORTH THE ASSUMPTIONS
MADE, MATTERS CONSIDERED AND QUALIFICATIONS AND LIMITATIONS ON THE REVIEW
UNDERTAKEN BY BEAR STEARNS, IS ATTACHED AS APPENDIX C TO THIS PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE SUMMARY OF THE
BEAR STEARNS OPINION SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE BEAR STEARNS OPINION.
HEALTHPLAN SERVICES STOCKHOLDERS ARE URGED TO READ CAREFULLY THE BEAR STEARNS
OPINION IN ITS ENTIRETY.

     The Bear Stearns opinion is intended for the benefit and use of the
HealthPlan Services Board, is directed only to the fairness to the stockholders
of HealthPlan Services, from a financial point of view, of the exchange ratio to
be provided for in the merger, does not address the merits of the underlying
decision by HealthPlan Services to engage in the merger and does not constitute
a recommendation to any holder of HealthPlan Services common stock or to the
HealthPlan Services Board as to how to vote on the merger or any related matter.

     Although Bear Stearns evaluated the fairness to the stockholders of
HealthPlan Services, from a financial point of view, of the exchange ratio to be
provided for in the merger, such exchange ratio was determined by HealthPlan
Services and UICI, through

                                      -34-
<PAGE>

arm's-length negotiations, which determination was not based on any
recommendation by Bear Stearns. Bear Stearns did provide certain advice to the
HealthPlan Services Board from time to time during the course of the
negotiations. The HealthPlan Services Board did not provide specific
instructions to, or place any limitations upon, Bear Stearns with respect to the
procedures to be followed or the factors to be considered by Bear Stearns in
performing its analyses or rendering the Bear Stearns opinion.

     In connection with rendering the opinion, Bear Stearns, among other things:

     o    reviewed the merger agreement and the option agreement discussed on
          pages 48 through 60 of this proxy statement;

     o    reviewed HealthPlan Services' Annual Reports to Stockholders and
          Annual Reports on Form 10-K for the fiscal years ended December 31,
          1997 and 1998, and its Quarterly Reports on Form 10-Q for the periods
          ended March 31, 1999 and June 30, 1999;

     o    reviewed certain operating and financial information, including
          projections, provided by the management of HealthPlan Services
          relating to HealthPlan Services' business and prospects;

     o    met with certain members of HealthPlan Services' senior management to
          discuss its operations, historical financial statements, recent
          financial results and near-term estimated financial performance, and
          future prospects;

     o    reviewed UICI's Annual Reports to Stockholders and Annual Reports on
          Form 10-K for the fiscal years ended December 31, 1997 and 1998, and
          its Quarterly Reports on Form 10-Q for the periods ended March 31,
          1999 and June 30, 1999;

     o    reviewed certain operating and financial information, including
          projections, provided by UICI management relating to UICI's business
          and prospects;

     o    met with certain members of UICI's senior management to discuss its
          operations, historical financial statements, recent financial results
          and near-term estimated financial performance, and future prospects;

     o    reviewed the historical prices and trading volumes of the common stock
          of HealthPlan Services and UICI;

     o    reviewed publicly available financial data, stock market performance
          data and valuation parameters of companies which Bear Stearns deemed
          generally comparable to HealthPlan Services and UICI;

     o    reviewed the terms of recent acquisitions of companies which Bear
          Stearns deemed generally comparable to HealthPlan Services;

     o    performed discounted cash flow analyses of the implied per share value
          of HealthPlan Services' common stock and of UICI's common stock based
          on the projections furnished to Bear Stearns by HealthPlan Services'

                                      -35-
<PAGE>

          management and UICI's management, respectively, as well as on a range
          of more conservative projection scenarios; and

     o    conducted such other studies, analyses, inquiries and investigations,
          as Bear Stearns deemed appropriate.

     In the course of its review, Bear Stearns relied upon and assumed, without
independent verification, the accuracy and completeness of the financial and
other information, including without limitation the projections, provided to it
by HealthPlan Services and UICI. With respect to HealthPlan Services' and UICI's
projected financial results, Bear Stearns assumed that they had been reasonably
prepared on bases reflecting the best currently available estimates and
judgements of the senior managements of HealthPlan Services and UICI as to the
expected future performance of HealthPlan Services and UICI, respectively. Bear
Stearns did not assume any responsibility for the independent verification of
any such information or of the projections provided to it, and Bear Stearns
further relied upon the assurances of the senior management of HealthPlan
Services and UICI that they were unaware of any facts that would make the
information or projections provided to it incomplete or misleading.
Notwithstanding Bear Stearns' reliance on the projections provided to it and on
the representations made to it by the managements of HealthPlan Services and
UICI with respect to such projections, in the course of Bear Stearns' analyses
for the purposes of rendering its opinion, Bear Stearns also considered the
valuation implications of more conservative projection scenarios for both
HealthPlan Services and UICI. In arriving at the opinion, Bear Stearns did not
perform or obtain any independent appraisal of the assets or liabilities of
HealthPlan Services and UICI, nor was Bear Stearns furnished with any such
appraisals. During the course of its engagement, Bear Stearns was asked by the
HealthPlan Services Board to solicit indications of interest from various third
parties regarding a transaction with HealthPlan Services, and Bear Stearns
considered the results of these solicitations in rendering its opinion. Bear
Stearns' opinion is necessarily based on economic, market and other conditions,
and the information made available to it, as of the date of the opinion. Bear
Stearns assumed that the merger will qualify as a tax-free "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended. Bear Stearns did not express any opinion as to the price or range of
prices at which shares of common stock of UICI may trade subsequent to the
merger.

     In connection with preparing and rendering the opinion, Bear Stearns
performed a variety of valuation, financial and comparative analyses. The
summary of the analyses, as set forth below, does not purport to be a complete
description of the analyses underlying the Bear Stearns opinion. The preparation
of a fairness opinion is a complex process and is not necessarily susceptible to
summary description. Bear Stearns believes that its analyses must be considered
as a whole, and that selecting portions of its analyses and the factors
considered by it, without considering all the factors and analyses, could create
an incomplete view of the processes underlying the opinion. Moreover, the
estimates contained in the analyses are not necessarily indicative of actual
values or predictive of future results or values, which may be significantly
more or less favorable than those suggested by the analyses. In addition,
analyses relating to the value of businesses or securities do not purport to be
appraisals or necessarily reflect the prices at which

                                      -36-
<PAGE>

businesses or securities actually may be sold. Accordingly, the estimates are
inherently subject to substantial uncertainties.

     The following is a summary of the material valuation, financial and
comparative analyses performed by Bear Stearns in arriving at the Bear Stearns
opinion as of the date thereof.

     HISTORICAL STOCK PRICE AND EXCHANGE RATIO ANALYSIS

     Bear Stearns reviewed the historical closing stock prices of HealthPlan
Services common stock and UICI common stock, including, among others, the one
year and three year periods prior to October 4, 1999. Over the prior twelve
months, HealthPlan Services' common stock had traded between a high of $11.50 on
October 21, 1998 and a low of $5.69 on August 11, 1999 and UICI's common stock
traded between a high of $29.00 on August 20, 1999 and a low of $11.75 on
October 15, 1998. Bear Stearns observed that based on

     -  the stock price of HealthPlan Services of $7.56 on October 4, 1999;

     -  the stock price of HealthPlan Services of $6.25 one month prior to
        October 4, 1999;

     -  the average stock price of HealthPlan Services of $6.72 for the twenty
        trading days prior to October 4, 1999;

     -  the average stock price of HealthPlan Services of $7.04 for the three
        months prior to October 4, 1999;

     -  the average stock price of HealthPlan Services of $7.58 for the six
        months prior to October 4, 1999;

     -  the average stock price of HealthPlan Services of $8.20 for the year
        prior to October 4, 1999; and

     -  an implied purchase price of $8.82 (based on a trading price for UICI's
        common stock of $26.00 per share and an exchange ratio of 0.3393),

     the implied purchase price represented implied premiums of 16.7%, 41.1%,
31.2%, 25.3%, 16.4% and 7.6%, respectively.

     Bear Stearns also reviewed the historical closing stock prices of
HealthPlan Services and UICI common stock and the implied market exchange ratios
determined by dividing the price per share of HealthPlan Services by the price
per share of UICI (the "Market Exchange Ratio") over various periods of time
including, among others, October 4, 1999 and the periods one week, two weeks,
six months and one year prior to October 4, 1999. Bear Stearns calculated that

     -  the Market Exchange Ratio was 0.2923 on October 4, 1999;

     -  the Market Exchange Ratio averaged 0.2847 for the one week prior to
        October 4, 1999;

                                      -37-
<PAGE>

     -  the Market Exchange Ratio averaged 0.2639 for the two weeks prior to
        October 4, 1999;

     -  the Market Exchange Ratio averaged 0.2758 for the six months prior to
        October 4, 1999; and

     -  the Market Exchange Ratio averaged 0.3773 for the one year period prior
        to October 4, 1999.

       Bear Stearns compared these figures to an assumed exchange ratio for the
merger of 0.3393.

     COMPARABLE PUBLIC COMPANY ANALYSIS

     In the course of its analysis, Bear Stearns compared certain ratios and
multiples of HealthPlan Services to the corresponding ratios and multiples of
certain publicly-traded companies in the four industry sectors that Bear Stearns
believed were generally comparable to HealthPlan Services: Healthcare Payors
(Humana, Inc., Coventry Health Care, Inc., Mid-Atlantic Medical Services, Inc.,
American Medical Security Group, Inc. and The Ceres Group); Non-Risk Bearing
Managed Care (First Health Group, Inc. and United Payors and United Providers,
Inc.); Non-Risk Bearing Managed Workers' Compensation (Crawford & Co., Corvel
Corporation and Core, Inc.); and Transaction Processing / Health Care
Information Systems (National Data Corporation, The Bisys Group, Inc., Inspire
Insurance Solutions, Inc., Health Management Systems, Inc. and Health Risk
Management). The multiples and ratios were calculated based on publicly
available financial information and research reports, and were adjusted for
certain extraordinary and non-recurring items. Financial data reviewed included
(i) revenue; (ii) earnings before interest, taxes, depreciation and amortization
("EBITDA"); (iii) earnings before interest and taxes ("EBIT"); (iv) net income;
and (v) earnings per share ("EPS") for various time periods as well as certain
operating margins, valuation statistics, financial ratios and projected growth
rates. For purposes of its analysis, Bear Stearns also reviewed the harmonic
means of certain valuation multiples of the comparable companies.

     Among other analyses, for each of the comparable companies, Bear Stearns
calculated the enterprise value multiples, which are the ratios of the sum of
their equity value as of October 4, 1999 plus debt less cash and cash
equivalents ("Enterprise Value") to their respective revenues, EBITDA and EBIT
during the most recently reported 12-month period ("LTM") and projected calendar
1999 and 2000 revenues, EBITDA and EBIT and the ratios of their stock prices as
of October 4, 1999 to their respective LTM earnings per share and projected
calendar year 1999 and 2000 earnings per share. Bear Stearns then compared the
calculated ratios and multiples of the comparable companies to the calculated
ratios and multiples for HealthPlan Services based on (i) the closing price for
HealthPlan Services on October 4, 1999 of $7.56 per share and (ii) the implied
purchase price for HealthPlan Services of $8.82 per share. These ratios are
summarized in the table below:

</TABLE>

      Bear Stearns observed that, based on the implied purchase price for
      HealthPlan Services of $8.82, the valuation multiples for HealthPlan
      Services generally equaled or exceeded the harmonic means of the trading
      multiples of the comparable companies.

      Bear Stearns chose the comparable companies because they have general
      business, operating and financial characteristics similar to those of
      HealthPlan Services, and Bear Stearns received guidance from HealthPlan
      Services management regarding the comparability of the selected companies.
      However, Bear Stearns noted that no company used in the foregoing analysis
      is identical to HealthPlan Services. Accordingly, Bear Stearns did not
      rely solely on the mathematical results of the analysis, but also made
      qualitative judgments concerning differences in financial and

                                      -39-
<PAGE>

     operating characteristics of HealthPlan Services and the comparable
     companies and other factors that could affect the values of each.

     COMPARABLE TRANSACTIONS ANALYSIS

     Bear Stearns reviewed certain publicly-available financial information
related to eight merger and acquisition transactions completed in the health
care administrative services sector since January 1, 1996 that it deemed
generally comparable to the merger. For each of the comparable transactions,
Bear Stearns reviewed certain publicly-available financial information for the
acquired companies including, to the extent available, revenue, EBITDA, EBIT,
net income and certain valuation statistics, as adjusted for certain
extraordinary and non-recurring items. The ratios of the Enterprise Values of
the acquired companies to their respective LTM revenues, EBITDA and EBIT and the
ratios of the equity value of the acquired companies to their respective LTM net
income are summarized in the table below and are compared to the calculated
ratios for HealthPlan Services based on the implied purchase price of $8.82.

     Bear Stearns observed that the exchange ratio of 0.3393 and the implied
purchase price of $8.82 produced multiples for HealthPlan Services that were
generally favorable as compared to the harmonic means of (i) Enterprise Value to
LTM revenues; (ii) Enterprise Value to LTM EBITDA; and (iii) equity value to the
projected forward calendar year period net income and a multiple which was not
favorable as compared to the harmonic mean of equity value to LTM net income of
the comparable transactions. Bear Stearns indicated that the relatively low LTM
net income multiple for HealthPlan Services was attributable to the expectation
that HealthPlan Services' net income in the third and fourth quarters of 1999
would decline significantly. Bear Stearns noted that no transaction used in the
foregoing analysis is identical to the merger. Bear Stearns also noted that
there was limited data available for the selected transactions, owing to the
fact that only one of the acquired companies was publicly traded. Accordingly,
Bear Stearns indicated that it did not place significant weight on this
valuation method.

     RELATIVE CONTRIBUTION ANALYSIS.

     Bear Stearns calculated the relative ownership by HealthPlan Services and
UICI of UICI following the merger (the "Combined Company") based on equity
market capitalization and Enterprise Value at a range of exchange ratios
provided for in the merger agreement. Bear Stearns then compared HealthPlan
Services' relative ownership percentages based on equity market capitalization
to the LTM and projected 1999 and 2000 net income contribution by HealthPlan
Services to the Combined Company and HealthPlan Services relative ownership
percentages based on Enterprise Value to the LTM and projected 1999 and 2000
revenue, EBITDA and EBIT contributions to the Combined Company, which projected
results were provided to Bear Stearns by the managements of HealthPlan Services
and UICI, respectively. In this relative contribution analysis, Bear Stearns did
not take into account any of the cost savings or synergies assumed by either
company to result from the merger.

     Bear Stearns calculated that using exchange ratios between the exchange
ratio of 0.3654 (the ratio that would apply assuming UICI average trading price
less than or equal to $21.00) and the maximum exchange ratio of 0.2969 (the
exchange ratio that would apply assuming UICI trading price of $35.00),
HealthPlan Services' stockholders would own between 8.1% and 9.7% of the
Combined Company based on equity market capitalization and between 8.0% and 8.7%
of the Combined Company based on Enterprise Value. Bear Stearns noted that the
ownership calculated using equity market capitalization compared to HealthPlan
Services' contribution of net income to the Combined Company of 7.2% for LTM and
projected 4.3% and 8.3% in 1999 and 2000, respectively. Bear Stearns also noted
that the ownership calculated using Enterprise Value compared to HealthPlan
Services' contribution to the Combined Company of (i) revenues of 15.8% for LTM
and projected 13.8% and 11.9% in 1999 and 2000, respectively; (ii) EBITDA of
12.7% for LTM and projected 12.4% in both 1999 and 2000; and (iii) EBIT of 8.0%
for LTM and projected 7.0% and 8.4% in 1999 and 2000, respectively.

     Bear Stearns performed a discounted cash flow analysis of HealthPlan
Services using stand-alone financial projections for HealthPlan Services
provided by HealthPlan Services' management for the years ending December 31,
2000 through December 31, 2004. Bear Stearns calculated a net present value of
the after-tax unlevered free cash flows for the years ending December 31, 2000
through December 31, 2004 as of December 31, 1999 using discount rates ranging
from 14.3% to 15.3%, based on the estimated weighted average cost of capital for
HealthPlan Services of 14.8%. Bear Stearns calculated a terminal value for
HealthPlan Services in the year 2004 using assumed perpetual growth rates of 2%
to 5%, applied to the projected 2005 free cash flow. These terminal values were
then discounted using discount rates ranging from 14.3% to 15.3%. Using this
analysis, the implied value per share of HealthPlan Services common stock (which
is the present value of the cash flows for the years December 31, 2000 through
December 31, 2004 plus the terminal value, less net debt, divided by the

                                      -41-
<PAGE>

outstanding shares of HealthPlan Services common stock plus the shares issuable
upon conversion of existing in-the-money options, assuming the proceeds of such
options are used to repurchase common stock) ranged from a low of $7.48 (based
on a discount rate of 15.3% and a perpetuity growth rate of 2%) to a high of
$11.98 (based on a discount rate of 14.3% and a perpetuity growth rate of 5%).
Bear Stearns also analyzed the sensitivity of the implied discounted cash flow
value per share of HealthPlan Services using more conservative projections than
those provided to Bear Stearns by HealthPlan Services' management. Using this
analysis at a discount rate of 14.8%, the implied value of HealthPlan Services
common stock ranged from a low of $4.12 per share (based on a projection
scenario where HealthPlan Services only achieved 80% of management's plan and a
terminal value calculated using a perpetuity growth rate of 2%) to a high of
$11.01 per share (based on a projection scenario where HealthPlan Services
achieved 100% of management's plan and a terminal value calculated using a
perpetuity growth rate of 5%).

     PRO FORMA MERGER ANALYSIS

     Bear Stearns reviewed and analyzed certain pro forma financial impacts of
the merger on the holders of HealthPlan Services common stock and UICI common
stock based on:

     -  a price for UICI common stock of $26.00 per share, the mid-day trading
        price on October 4, 1999;

     -  46.267 million diluted shares of UICI outstanding and 13.662 million
        diluted shares of HealthPlan Services common stock outstanding;

     -  an exchange ratio of 0.3393;

     -  EPS projections for HealthPlan Services and UICI which were based on the
        projections provided to Bear Stearns by the managements of HealthPlan
        Services and UICI, respectively;

     -  accounting for the merger as a "purchase" with an assumed amortization
        period for goodwill incurred in the acquisition of 20 years; and

     -  no assumed cost savings or synergies.

     The results of the analysis indicated that, without cost savings or
     synergies, the acquisition of HealthPlan Services by UICI would result in
     dilution of the projected EPS of UICI common stock of $0.05 or 2.2% for
     calendar year 2000 and dilution of $0.02 or 0.9% for calendar year 2001, as
     compared to the projected EPS of UICI common stock on a stand-alone,
     pre-acquisition basis. Bear Stearns calculated that pre-tax synergies of
     approximately $4.2 million in 2000 and $2.1 million in 2001 would be
     required in order for UICI to achieve break-even (non-dilutive) EPS. These
     required synergies compared favorably to HealthPlan Services management's
     estimates for combination synergies.

                                      -42-

     OTHER ANALYSES

     Bear Stearns conducted such other analyses as it deemed necessary,
including the following:

     -  reviewing historical and projected financial and operating data for both
        HealthPlan Services and UICI;

     -  analyzing selected investment research reports on, and earnings and
        other estimates for, each of HealthPlan Services and UICI;

     -  analyzing the historic stock performance and trading volume for
        HealthPlan Services and UICI;

     -  reviewing available information regarding the institutional holdings of
        HealthPlan Services common stock and UICI common stock.

     The HealthPlan Services Board engaged Bear Stearns as its financial advisor
based on Bear Stearns' experience and expertise. Bear Stearns is an
internationally recognized investment banking firm that has substantial
experience in the health care industry and expertise in transactions similar to
the merger. As part of its investment banking business, Bear Stearns is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Pursuant to the terms
of its engagement letter, dated February 15, 1999, HealthPlan Services has
agreed to pay Bear Stearns the following compensation:

     -  a fee of $600,000 in connection with the delivery of the Bear Stearns
        opinion;

     -  a transaction fee, contingent upon and payable at closing of the merger,
        of 1% of the total consideration to be paid by UICI in the merger
        against which the opinion fee is to be credited, which transaction fee
        is estimated at approximately $2.1 million; and

     -  to reimburse Bear Stearns for all reasonable out-of-pocket expenses,
        including fees and disbursements of counsel, and of other consultants
        and advisors retained by Bear Stearns.

HealthPlan Services has also agreed to indemnify Bear Stearns and certain
related persons against certain liabilities in connection with its engagement,
including certain liabilities under the federal securities laws. Insofar as
indemnification for liabilities arising under the Securities Act of 1933, as
amended, may be permitted to Bear Stearns pursuant to the foregoing provisions,
Bear Stearns and HealthPlan Services have been informed that in the opinion of
the SEC, such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable. In the ordinary course of
business, Bear Stearns may actively trade the equity securities of HealthPlan
Services and UICI for its own account and for the accounts of its customers and,
accordingly, may at any time hold a long or short position in the securities.

EFFECTIVE TIME OF THE MERGER

     Unless the parties to the merger agree to a later time and date, the merger
will become effective when we file a certificate of merger with the Secretary of
State of Delaware. Unless we agree otherwise, we will complete the merger on the
second business day after all of the conditions to the merger are satisfied or
waived. We expect to complete the merger by January 31, although we can give no
assurance when, or if, all the conditions to completion of the merger will be
satisfied or waived. See "-- REGULATORY APPROVALS" and "THE MERGER AGREEMENT AND
RELATED AGREEMENTS-- CONDITIONS TO EACH COMPANY'S OBLIGATIONS TO COMPLETE THE
MERGER."

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is intended to be only a summary of the material
U.S. federal income tax consequences of the merger and not a complete analysis
or listing of all potential tax effects relative to a decision whether to vote
for the approval of the merger agreement and the merger. The discussion does not
address all aspects of U.S. federal income taxation that may apply to HealthPlan
Services stockholders who are subject to special U.S. federal income tax
treatment, including non-U.S. persons, insurance companies, tax-exempt entities,
retirement plans and persons who acquired their HPS Common Shares upon the
exercise of employee stock options or otherwise as compensation. For example,
the discussion does not address the effect, if any, of the Foreign Investment In
Real Property Tax Act on non-U.S. persons holding HPS Common Shares. The
discussion below applies to HealthPlan Services stockholders who hold their HPS
Common Shares as a capital asset within the meaning of Section 1221 of the
Internal Revenue Code. The discussion addresses neither the effect of applicable
state, local or non-U.S. tax laws, nor the effect of any U.S. federal tax laws
other than those pertaining to U.S. federal income tax.

     OPINIONS

     It is a condition of the merger that HealthPlan Services receive an opinion
of counsel to the effect that:

     o    the merger will be treated as a reorganization described in Section
          368(a) of the Internal Revenue Code; and

     o    stockholders of HealthPlan Services who are United States persons and
          who exchange HPS Common Shares solely for shares of common stock of
          UICI in the merger will not recognize any gain or loss as a result of
          such exchange (except with respect to cash received instead of
          fractional shares).

     It is a condition of the merger that UICI receive an opinion of counsel to
the effect that:

                                      -44-
<PAGE>

     o    the merger will be treated as a reorganization described in Section
          368(a) of the Internal Revenue Code.

     Opinions of counsel are not equivalent to rulings from the Internal Revenue
Service, and such opinions are not binding on the Internal Revenue Service. The
Internal Revenue Service and ultimately the courts could disagree with the
opinions. The opinions will be based on the Internal Revenue Code, the
regulations under the Internal Revenue Code, administrative rulings of the IRS
and court decisions, all of which are subject to change. Any such change, which
may or may not be retroactive, could alter the tax consequences discussed below.
The opinions will also be based on customary assumptions and representations
made by HealthPlan Services, its principal stockholders, and UICI. The
discussion below assumes that the merger will be treated as a reorganization
described in Section 368(a) of the Internal Revenue Code.

     Except with respect to cash received in lieu of fractional shares, you will
not recognize any gain or loss on the exchange of HPS Common Shares for common
stock of UICI. The tax basis of the shares of common stock of UICI you receive
in the merger will be equal to the tax basis of the HPS Common Shares you
exchange for those shares, reduced by any amount of basis allocable to
fractional share interests for which you receive cash. For determining whether
gain or loss on the subsequent disposition of shares of common stock of UICI
received in the merger is long-term or short-term, the holding period of the
shares of common stock of UICI you receive will include the holding period of
the HPS Common Shares you exchanged for those shares.

     The receipt of cash in lieu of a fractional share of common stock of UICI
by you in the merger will result in taxable gain or loss to you for U.S. federal
income tax purposes based on the difference between the amount of cash you
receive and your basis in the fractional share as described above. That gain or
loss will be a capital gain or loss and will be a long-term or short-term
capital gain or loss, depending on your holding period in the HPS Common Shares.

     Backup withholding at a rate of 31% will apply to any cash payments to you
unless either (1) you provide or have provided your taxpayer identification
number (social security or employer identification number) and certify that the
number is correct or (2) an exemption from backup withholding applies under the
applicable law and regulations.

     THE FOREGOING DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. BECAUSE OF THE
COMPLEXITY OF THE TAX LAWS, AND BECAUSE THE TAX CONSEQUENCES TO ANY PARTICULAR
STOCKHOLDER MAY BE AFFECTED BY MATTERS NOT DISCUSSED IN THIS PROXY
STATEMENT/PROSPECTUS, YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO
YOUR OWN PARTICULAR CIRCUMSTANCES AND WITH RESPECT TO THE SPECIFIC TAX
CONSEQUENCES OF THE MERGER TO YOU, INCLUDING THE APPLICABILITY AND EFFECT OF
STATE, LOCAL AND NON-U.S. TAX LAWS, ESTATE TAX LAWS AND PROPOSED CHANGES IN
APPLICABLE TAX LAWS. NON-U.S. PERSONS, IF ANY, WHO HOLD OR HAVE HELD (DIRECTLY,
CONSTRUCTIVELY OR BY ATTRIBUTION)

                                      -45-
<PAGE>

MORE THAN 5% OF THE OUTSTANDING HPS COMMON SHARES SHOULD CONSULT THEIR TAX
ADVISORS REGARDING THE CONSEQUENCES TO THEM OF THE MERGER UNDER THE FOREIGN
INVESTMENT IN REAL PROPERTY TAX ACT, INCLUDING ANY TAX FILING REQUIREMENTS THAT
MAY APPLY.

ACCOUNTING TREATMENT

     We expect that the merger will be treated as a "purchase" for accounting
purposes. Under this method of accounting, UICI must determine the purchase
price based on the consideration paid in the acquisition. The fair value of the
acquired net tangible assets is recorded by UICI as of the date on which the
acquisition is consummated. The excess of purchase price over net tangible
assets acquired is required to be assigned among identifiable intangible assets
based on fair value. These identifiable intangible assets may include, among
other things, incomplete technology, complete technology, brands and trademarks,
customer lists, employment contracts and copyrights. Any excess purchase price
over the acquired net tangible assets that is not assigned to identifiable
intangible assets is classified as goodwill. The amounts recorded for intangible
assets and goodwill are required to be amortized by systematic charges to income
over the estimated periods of benefit and estimated useful life.

REGULATORY APPROVALS - ANTITRUST CLEARANCE

     The Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the related
rules and regulations prohibit us from completing the merger until we submit
required information to the Antitrust Division of the Department of Justice and
the Federal Trade Commission ("FTC") and specified Hart-Scott-Rodino Antitrust
Improvement Act waiting period requirements have been satisfied. Even after the
Hart-Scott-Rodino Antitrust Improvement Act waiting period expires or
terminates, the Antitrust Division or the FTC may later challenge the merger on
antitrust grounds. We do not believe that the merger will violate federal
antitrust laws.

LISTING OF UICI COMMON STOCK ON STOCK EXCHANGES

     We have agreed to take all reasonably required actions to obtain approvals
to list the shares of common stock of UICI to be issued in the merger on the New
York Stock Exchange, subject to official notice of issuance. Approval for
listing on the New York Stock Exchange is a condition to the merger.

RESALE OF SHARES ISSUED IN THE MERGER; AFFILIATES

     The common stock of UICI issued to HealthPlan Services stockholders in the
merger will be freely transferable under the Securities Act, except for shares
issued to an affiliate of HealthPlan Services for purposes of Rule 145 under the
Securities Act. These persons may not sell UICI common stock that they acquired
in the merger except under an effective registration statement under the
Securities Act, or in compliance with Rule 145 under the Securities Act or
another applicable exemption from the registration

                                      -46-
<PAGE>

requirements of the Securities Act. The merger agreement requires HealthPlan
Services to use its reasonable best efforts to cause each of its affiliates to
execute a written agreement to comply with the foregoing requirements.

BOARD OF DIRECTORS AND MANAGEMENT OF HEALTHPLAN SERVICES AFTER THE MERGER

     When we complete the merger, James K. Murray, Jr., currently the Chairman
of the HealthPlan Services Board, will become a member of the UICI board. The
Board of Directors of HealthPlan Services which will be a wholly-owned
subsidiary of UICI following the merger will consist of Gregory T. Mutz
(President and Chief Executive Officer of UICI), Steven K. Arnold (Vice
President of UICI), Glenn W. Reed (Executive Vice President and General Counsel
of UICI), William L. Bennett (currently Vice Chairman of HealthPlan Services)
and Phillip S. Dingle (currently Executive Vice President and Chief Financial
Officer of HealthPlan Services). It is expected that Steven K. Arnold, currently
head of UICI's student health insurance division, will become President and
Chief Executive Officer at HealthPlan Services. Steven V. Huslander, George E.
Lucco, Jeffrey W. Bak and Jeffrey Markle, currently officers of HealthPlan
Services, are expected to assume similar positions with HealthPlan Services
following the merger. Phillip S. Dingle is expected to become the Chief
Financial Officer of UICI following the merger.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the Board that stockholders vote for
approval of the merger agreement and the merger, you should be aware that
certain members of HealthPlan Services management and of the HealthPlan Services
Board have interests in the merger that may be considered different from, or in
addition to, the interests of the stockholders of HealthPlan Services generally.
The HealthPlan Services Board was aware of these interests and considered them
when it approved the merger agreement and the merger. See also "THE MERGER
AGREEMENT AND RELATED AGREEMENTS - INDEMNIFICATION AND INSURANCE," "THE MERGER
AGREEMENT AND RELATED AGREEMENTS - HEALTHPLAN SERVICES STOCK OPTIONS" and "THE
MERGER AGREEMENT AND RELATED AGREEMENTS - EMPLOYMENT AGREEMENTS" for a
description of additional interests of these individuals.

     BONUS

     Under the terms of the 1999 Annual Incentive Plan adopted by the HealthPlan
Services Board Compensation Committee in February 1999, upon completion of the
merger, James K. Murray, Jr., the Chairman and Chief Executive Officer of
HealthPlan Services, will be entitled to a bonus in the amount of $250,000.

     EMPLOYMENT AGREEMENTS

     We expect that prior to the time we complete the merger, Steven V.
Huslander, George E. Lucco, Jeffrey W. Bak and Jeffrey Markle, currently
officers of HealthPlan

                                      -47-
<PAGE>

Services, will enter into employment agreements with HealthPlan Services and
assume similar positions with HealthPlan Services following the merger. Phillip
S. Dingle is expected to enter into an employment agreement with UICI and become
the Chief Financial Officer of UICI following the merger.

     Under the employment agreements with HealthPlan Services (and, with respect
to Mr. Dingle, with UICI), which are expected to have a two-year base term and a
two-year extension option, these individuals are expected to receive the
following compensation and benefits:

     o    base annual salaries of $200,000;

     o    annual performance bonuses;

     o    one-time restricted stock grants, at levels commensurate with current
          employees of UICI at corresponding salary levels, subject to five-year
          vesting restrictions;

     o    one-time stock option grants at levels commensurate with current
          employees at corresponding salary levels, subject to five-year vesting
          restrictions;

     o    participation in UICI's Senior Officer Share Purchase and Loan
          Program; and

     o    upon termination of employment, employees will be subject to usual and
          customary non-compete and non-solicitation restrictions.

     SEVERANCE POLICIES

     Alan M. Ross, Senior Vice President-Human Resources of HealthPlan Services,
has an employment agreement providing for payment of severance upon a
change-in-control prior to December 31, 1999 in which the successor company does
not offer Mr. Ross the position of chief human resources officer. The severance
is a lump sum amount equal to one and one-half times salary and bonus. Mr. Ross'
current salary and target bonus is $218,400.

                   THE MERGER AGREEMENT AND RELATED AGREEMENTS

     The following is a description of the material provisions of the merger
agreement, a copy of which is attached as Appendix A to this proxy
statement/prospectus and incorporated herein by reference. This description may
not include all of the information that interests you. We urge you to read the
entire merger agreement.

THE MERGER AGREEMENT

     The merger agreement provides that New UICI Sub will merge into HealthPlan
Services with HealthPlan Services being the surviving corporate entity.
Following the merger, HealthPlan Services will be a wholly-owned subsidiary of
UICI. The merger will occur after the approval of the merger by HealthPlan
Services stockholders and the

                                      -48-
<PAGE>

satisfaction or waiver of the other conditions to the merger described in the
merger agreement.

     The merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of Delaware as required by Delaware law.

     EXCHANGE RATIO

     Pursuant to the merger agreement, in the merger, each outstanding HPS
Common Share will be converted into the right to receive a fraction of a share
of UICI common stock. The fraction will be determined based on an exchange ratio
that is, in turn, based on the average of the volume weighted average of the
trading prices of UICI stock for a period of 20 consecutive trading days ending
on the third trading day immediately prior to the effective date of the merger.
The exchange ratio will be calculated as follows:
<TABLE>
<CAPTION>
          PRICE RANGE OF UICI STOCK (PER SHARE)                          EXCHANGE RATIO
          -------------------------------------                          --------------

<S>                                                         <C>
o     Greater than $33.00                                   $9.50 / (average price of UICI stock - $3.00)

o     Less than or equal to $33.00 and greater
      than $30.00                                           .3167

o     Less than or equal to $30.00, but greater
      than or equal to $28.00                               $9.50 / (average price of UICI stock)

o     Less than $28.00, but greater than or equal
      to $23.00                                             .3393

o     Less than $23.00, but greater than or equal
      to $21.00                                             $9.50 / (average price of UICI stock + $5.00)

o     Less than $21.00                                      .3654
</TABLE>

     In no event, however, will you receive a fractional share of UICI common
stock. Instead, if you would otherwise be entitled to receive a fractional share
of UICI stock, you will be paid an amount in cash equal to such fraction
multiplied by the average of the closing price for UICI common stock on the New
York Stock Exchange for the five trading days immediately preceding the
effective date of the merger.

     CONVERSION OF HPS COMMON SHARES

     IT IS VERY IMPORTANT THAT YOU NOT SEND IN YOUR HPS COMMON SHARE
CERTIFICATES UNTIL YOU RECEIVE TRANSMITTAL INSTRUCTIONS FROM THE EXCHANGE AGENT.

     EXCHANGE AGENT

     UICI will deposit shares of UICI common stock to be issued in the merger
with an exchange agent selected by UICI and HealthPlan Services.

                                      -49-
<PAGE>

     EXCHANGE PROCEDURES

     As soon as practical after we complete the merger, the exchange agent will
mail a transmittal letter and instructions to each holder of HPS Common Shares
of record at the close of business the day before the effective time of the
merger. The instructions will explain exactly what you need to do to convert
your HPS Common Shares into shares of UICI common stock.

     After the effective time of the merger, each holder of HPS Common Shares
will have the right to receive shares of common stock of UICI, but you will not
receive your shares until you have complied with the exchange agent's
instructions and submitted the required documents, including share certificates.
The exchange agent will not issue any fractional shares that result from the
conversion of HPS Common Shares, but will instead issue a check for the value of
any fractional share determined as described below under "EXCHANGE RATIO."

     TRANSFER OF OWNERSHIP

     Any certificates representing HPS Common Shares will be delivered, AND RISK
OF LOSS AND TITLE WILL PASS TO THE EXCHANGE AGENT, ONLY when the exchange agent
receives such certificates. We URGE you to mail your certificates by certified
mail or some other secure method when you receive instructions to do so from the
exchange agent.

     PAYMENTS FOLLOWING SURRENDER

     If you have not exchanged your HPS Common Shares for shares of UICI common
stock as described above, you will not receive any dividends or other
distributions declared or made after the effective time of the merger. Once you
have exchanged your HPS Common Shares, you will be entitled to receive, without
interest:

     o    any cash payable instead of a fractional share of UICI common stock to
          which you are entitled; and

     o    any dividends or other distributions paid after the effective time of
          the merger on whole shares of UICI common stock, but before your HPS
          Common Shares were exchanged.

REPRESENTATIONS AND WARRANTIES

     The merger agreement contains various customary representations and
warranties of UICI and HealthPlan Services relating to, among other things:

     o    organization and similar corporate matters;

     o    capital structure;

                                      -50-
<PAGE>

     o    authorization, execution, delivery, performance and enforceability of
          the merger agreement and related matters;

     o    conflicts under certificates of incorporation or bylaws, required
          consents or approvals and violations of instruments or law;

     o    documents filed with the SEC and the accuracy of the information
          contained therein;

     o    absence of specified material changes, material undisclosed
          liabilities or material defaults;

     o    environmental matters;

     o    Year 2000 readiness;

     o    the accuracy of information supplied by each of UICI and HealthPlan
          Services in connection with the preparation of the Registration
          Statement and this proxy statement/prospectus; and

     o    absence of material litigation.

     HealthPlan Services also represented and warranted as to:

     o    tax, employee and employee benefit matters;

     o    intellectual property matters;

     o    the receipt of a fairness opinion from its financial advisor;

     o    compliance with applicable law; and

     o    that it has not proposed, adopted, approved or implemented any
          stockholder rights plan.

CONDUCT OF BUSINESS PRIOR TO THE EFFECTIVE TIME

     HealthPlan Services has agreed that until the merger is complete or the
merger agreement is terminated, it will conduct its business in the ordinary and
usual course consistent with past practice, and will use its reasonable efforts
to preserve intact its present business organization, will keep available the
services of its present officers and key employees, will preserve the goodwill
of those having business relationships with it and will not hire any person as
an employee or consultant where such person's annual compensation would exceed
$100,000.

                                      -51-
<PAGE>

     In addition, HealthPlan Services has agreed to certain customary
restrictions on the conduct of its business as to:

     o    organizational documents;

     o    dividends and distributions;

     o    changes in capital structure;

     o    acquisition or disposition of stock and related securities;

     o    acquisitions and other uses of funds;

     o    disposition of assets;

     o    incurrence or guarantee of indebtedness;

     o    capital expenditures;

     o    employee benefit plans and similar arrangements;

     o    compensation for directors, officers and employees;

     o    accounting matters; and

     o    tax matters.

     UICI has agreed that until the merger is completed or the merger agreement
is terminated (and except as specifically stated in the merger agreement), it
will conduct its business in the ordinary and usual course consistent with past
practice, and will use its reasonable efforts to preserve intact its present
business organization, keep available the services of its present officers and
key employees, and preserve the goodwill of those having business relationships
with it.

     In addition UICI has agreed to certain customary restrictions for the
conduct of its business as to:

     o    dividends and distributions;

     o    changes in capital structure; and

     o    accounting policies.

                                      -52-
<PAGE>

     Each company has also agreed that it and each of its subsidiaries will:

     o    provide copies of filings and access to books and records; and

     o    use commercially reasonable efforts to obtain all necessary waivers,
          consents and approvals.

NO SOLICITATION OF COMPETING TRANSACTIONS

     The merger agreement requires that HealthPlan Services not, directly or
indirectly, through any officer, director, agent or otherwise:

     o    initiate, solicit or knowingly encourage, or take any other action
          knowingly to facilitate the making of an Alternative Acquisition (as
          defined below); or

     o    engage in negotiations with any person relating to an Alternative
          Acquisition, or agree to or endorse any Alternative Acquisition, or
          authorize any of the officers, directors or employees of HealthPlan
          Services or any investment banker, financial advisor, attorney,
          accountant or other agent or representative of HealthPlan Services to
          take any such action.

     An "Alternative Acquisition" means any of the following transactions (other
than the transactions contemplated by the merger agreement) that would result in
a third party (or its stockholders) acquiring more than 35% of the voting power
of the shares of the common stock of HealthPlan Services then outstanding or
more than 35% of the assets of HealthPlan Services and its subsidiaries, taken
as a whole:

     o    merger, consolidation, share exchange, business combination, issuance
          or purchase of securities or other similar transaction;

     o    sale, lease, exchange, mortgage, pledge, transfer or other disposition
          of the assets of HealthPlan Services in a single transaction or series
          of related transactions;

     o    tender offer or exchange offer for HealthPlan Services securities or
          the filing of a registration statement under the Securities Act in
          connection with any such exchange offer transaction; or

     o    public announcement of an agreement, proposal, plan or intention to do
          any of the foregoing, either during the effectiveness of the merger
          agreement or at any time thereafter.

     HealthPlan Services will notify UICI within 24 hours of all inquiries and
proposals which HealthPlan Services may receive relating to any of such matters.

     However, these restrictions will not prevent the HealthPlan Services Board
from taking any of the following actions:

                                      -53-
<PAGE>

     o    furnishing information to, or entering into and engaging in
          discussions or negotiations with, any person that makes a bona fide
          unsolicited written proposal that the HealthPlan Services Board
          determines in good faith, after consultation with its financial
          advisors and independent legal counsel, can be reasonably expected to
          result in a Superior Proposal (as defined below). However, prior to
          furnishing any information to, or entering into discussions or
          negotiations with, any person, HealthPlan Services must, (1) notify
          UICI and keep UICI informed of the status and material terms of any
          such proposal and the status of any such discussions and negotiations,
          and (2) receive from such person a confidentiality agreement;

     o    complying with Rule 14e-2 under the Exchange Act with regard to a
          tender or exchange offer or making any disclosure required under
          applicable law; or

     o    failing to make or withdrawing or modifying its recommendation of the
          merger following the making of a Superior Proposal if the Board of
          Directors of HealthPlan Services, after consultation with and based
          upon the advice of independent legal counsel, determines in good faith
          that such action is necessary for the Board of Directors of HealthPlan
          Services to comply with its fiduciary duties under applicable law.

     A "Superior Proposal" means any proposal which would result in a party
acquiring, directly or indirectly, including pursuant to a tender offer,
exchange offer, merger, consolidation, share exchange, business combination,
share purchase, asset purchase, recapitalization, liquidation, dissolution,
joint venture or similar transaction, more than 50% of the voting power of the
shares of the common stock of HealthPlan Services then outstanding or all or
substantially all the assets of HealthPlan Services and its subsidiaries, taken
as a whole, for consideration which the Board of Directors of HealthPlan
Services determines in its good faith judgment to be financially more favorable
to HealthPlan Services stockholders than the merger and with respect to which
the Board of Directors of HealthPlan Services determines, in its good faith
judgment, that financing, to the extent required, is then committed or is
reasonably available.

INDEMNIFICATION AND INSURANCE

     The merger agreement provides that all rights to indemnification,
advancement of litigation expenses and limitation of personal liability existing
in favor of the directors and officers of HealthPlan Services under the
provisions existing as of the date of the merger agreement in HealthPlan
Services' certificate of incorporation or bylaws will, with respect to any
matter existing or occurring at or prior to the effective time of the merger
(including the transactions contemplated by the merger agreement), survive the
merger, and, as of the effective time of the merger, the surviving company in
the merger will assume all such obligations of HealthPlan Services and no change
will be made with respect to such rights after the merger.

     UICI also agreed that for six years after the merger, it will maintain in
effect the policies of directors' and officers' liability insurance maintained
by HealthPlan Services or policies containing substantially similar coverage for
matters occurring at or prior to
                                      -54-
<PAGE>

the effective time. UICI will not be required, however, to pay more than 200% of
the current annual premiums for the policies currently maintained by HealthPlan
Services for its directors' and officers' liability insurance. If insurance
cannot be maintained or obtained at such cost, UICI will maintain or obtain as
much of such insurance as can be so maintained or obtained at a cost equal to
200% of the current annual premiums of HealthPlan Services for its directors'
and officers' liability insurance.

HEALTHPLAN SERVICES STOCK OPTIONS

     HealthPlan Services has granted stock options pursuant to the HealthPlan
Services Corporation 1995 Incentive Equity Plan, the HealthPlan Services
Corporation 1995 Director's Stock Option Plan, the 1995 HealthPlan Services
Corporation Consultants Stock Option Plan, the Amended and Restated HealthPlan
Services Corporation 1996 Employee Stock Option Plan and the HealthPlan Services
Corporation 1996 Employee Stock Purchase Plan. Under these plans (other than the
1996 Employee Stock Purchase Plan), options vest 20% on the date of grant and
20% on each of the first through fourth anniversaries of the date of grant of
such option.

     Under the terms of the merger agreement, each HealthPlan Services stock
option that is outstanding immediately prior to the effective time will be
converted into a new option to purchase the number of shares of UICI Common
Stock equal to the product of (i) the number of HPS Common Shares subject to
such stock option and (ii) the exchange ratio. The exercise price for such new
option will equal (x) the per share exercise price of such HealthPlan Services
stock option, divided by (y) the exchange ratio. After the merger, each new
option will be exercisable and will vest upon the same terms and conditions as
were applicable to the related HealthPlan Services stock option immediately
prior to the merger.

CONDITIONS TO EACH COMPANY'S OBLIGATIONS TO COMPLETE THE MERGER

     The merger will occur only if the merger agreement is approved by the
requisite vote of holders of HPS Common Shares. In addition, consummation of the
merger is subject to the satisfaction or waiver (to the extent such waiver is
permitted by law) of certain other conditions, including:

     o    any waiting period applicable to the merger under the
          Hart-Scott-Rodino Act having expired or been terminated and no action
          can be pending by the FTC or the Antitrust Division of the Department
          of Justice challenging or seeking to enjoin the merger;

     o    no statute, rule, regulation, executive order, decree, injunction or
          other order being in effect that materially restricts, prevents or
          prohibits completion of the merger or any transaction contemplated by
          the merger agreement;

                                      -55-
<PAGE>

     o    all filings, approvals and consents of any governmental entity, the
          failure of which to obtain would have a material adverse effect on
          either UICI or HealthPlan Services, having been made or obtained;

     o    the Registration Statement of which this proxy statement/prospectus is
          a part having become effective under the Securities Act and not being
          subject to a stop order or proceeding of the SEC seeking a stop order,
          and UICI having received all state securities or "blue sky" permits
          and other authorizations necessary to issue the UICI common stock in
          the merger; and

     o    the UICI common stock in the merger having been approved for listing
          on the New York Stock Exchange, upon official notice of issuance.

     CONDITIONS TO OBLIGATIONS OF UICI

     The obligation of UICI to complete the merger is subject to the following
additional conditions:

     o    each of the representations and warranties of HealthPlan Services
          being true and correct (without regard to any materiality qualifiers)
          as of the date of the merger agreement and, except to the extent the
          representations and warranties speak as of an earlier date, being true
          and correct as of the effective time of the merger as though made at
          the effective time, except where the failure to be true and correct
          would not, individually or in the aggregate, have a material adverse
          effect on HealthPlan Services;

     o    HealthPlan Services having performed in all material respects all
          obligations required to be performed by it under the merger agreement;

     o    UICI having received a certificate of the Chief Executive Officer or
          the Chief Financial Officer of HealthPlan Services that specified
          conditions in the merger agreement have been fulfilled;

     o    UICI having received from each "affiliate" of HealthPlan Services a
          written agreement that such affiliate will not sell any shares of UICI
          common stock received in the merger, except in compliance with the
          requirements of the Securities Act;

     o    UICI having received an opinion of Gardner, Carton & Douglas, counsel
          to UICI, that the merger will constitute a "reorganization" within the
          meaning of Section 368(a) of the Internal Revenue Code; and

     o    UICI having received the resignations of each board member of
          HealthPlan Services, other than William L. Bennett.

                                      -56-
<PAGE>

     CONDITIONS TO OBLIGATIONS OF HEALTHPLAN SERVICES

     The obligation of HealthPlan Services to complete the merger is subject to
the following additional conditions:

     o    the representations and warranties of UICI being true and correct
          (without regard to any materiality qualifiers) as of the date of the
          merger agreement and, except to the extent the representations and
          warranties speak as of an earlier date, being true and correct as of
          the effective time of the merger as though made at the effective time,
          except where the failure to be true and correct would not,
          individually or in the aggregate, have a material adverse effect on
          UICI;

     o    UICI having performed in all material respects all obligations
          required to be performed by it under the merger agreement;

     o    HealthPlan Services having received a certificate of the Chief

          conditions specified in the merger agreement have been fulfilled; and

     o    HealthPlan Services having received an opinion of Fowler, White,
          Gillen, Boggs, Villareal and Banker P.A., counsel to HealthPlan
          Services, that the merger will constitute a "reorganization" within
          the meaning of Section 368(a) of the Internal Revenue Code.

     TERMINATION AND TERMINATION FEE

     The merger agreement may be terminated at any time before the merger
becomes effective:

     o    by mutual consent of UICI and HealthPlan Services;

     o    by either UICI or HealthPlan Services if the merger has not become
          effective before March 31, 2000;

     o    by either UICI or HealthPlan Services if the HealthPlan Services
          stockholders do not approve the merger agreement and the merger;

     o    by either UICI or HealthPlan Services if any permanent injunction or
          action by any governmental entity preventing the completion of the
          merger has become final and non-appealable;

     o    by either UICI or HealthPlan Services if there has been a breach of
          any representation or warranty of the other party which, individually
          or in the aggregate, would have a material adverse affect on that
          other party or if there has been a breach in any material respect of
          any agreement or

                                      -57-
<PAGE>

          covenant to be performed and complied with by that other party under
          the merger agreement and the breach is not curable, or if curable, is
          not cured within 30 days after written notice of such breach is given
          to that other party by the party not in breach;

     o    by UICI if the bank or financial institution under any financing
          commitment fails to fund the loan to UICI because of a material
          adverse change in the financial markets;

     o    by UICI if the HealthPlan Services Board (x) fails to recommend
          approval of the merger agreement by the stockholders of HealthPlan
          Services or withdraws or amends or modifies in a manner adverse to
          UICI and New UICI Sub its recommendation or approval of the merger
          agreement, (y) makes any recommendation with respect to an Alternative
          Acquisition other than a recommendation to reject such Alternative
          Acquisition or (z) takes any action regarding an Alternative
          Acquisition that would be prohibited by the "no solicitation"
          provisions of the merger agreement; or

     o    by HealthPlan Services if such termination is necessary to allow
          HealthPlan Services to enter into an agreement with respect to a
          Superior Proposal (subject to prior payment of the termination fee as
          described below).

     If the merger agreement is terminated, the merger will be deemed abandoned
and such termination will be without liability of any party under the merger
agreement except for liability for breach of the merger agreement and except as
set forth below in the following paragraph regarding termination fees.

     If the merger agreement is terminated by UICI because the HealthPlan
Services Board fails to recommend approval of the merger (or withdraws or
modifies its recommendation), makes any recommendation with respect to an
Alternative Acquisition other than a recommendation to reject such Alternative
Acquisition, or takes any action regarding an Alternative Acquisition that would
be prohibited by the "no solicitation" provisions of the merger agreement as
described above, then HealthPlan Services must pay to UICI within two business
days after such termination a fee of $5 million. Similarly, if HealthPlan
Services terminates the merger agreement in order to accept a Superior Proposal,
then HealthPlan Services must pay UICI within two business days of such
termination a fee of $5 million. If the merger agreement is terminated due to
the failure of HealthPlan Services' stockholders to approve the merger
agreement, and at or prior to the time of the failure to approve the merger
agreement an Alternative Acquisition has been made public, and within eighteen
months of such termination an Alternative Acquisition with any third party is
completed or an agreement relating to an Alternative Acquisition is entered into
by HealthPlan Services, then HealthPlan Services must pay UICI a termination fee
of $5 million.

     Whether or not the merger is completed, all costs and expenses incurred in
connection with the merger agreement and the transactions contemplated thereby
will be

                                      -58-
<PAGE>

paid by the party incurring such expense, except that the following expenses
will be borne equally by UICI and HealthPlan Services:

     o    the filing fee in connection with the filings under the
          Hart-Scott-Rodino Antitrust Improvements Act;

     o    the expenses incurred in connection with printing and mailing this
          proxy statement/prospectus; and

     o    the filing fee with the SEC relating to the registration statement or
          proxy statement.

     EXTENSION, WAIVER AND AMENDMENT

     At any time prior to the effective time of the merger, UICI or HealthPlan
Services may extend the time for performance of any obligations or other acts of
the other under the merger agreement, waive any inaccuracies in the
representations and warranties of the other contained in the merger agreement or
waive compliance by the other with any agreements contained in the merger
agreement or with any conditions that may legally be waived.

     The merger agreement may not be amended except in writing. The merger
agreement may be amended without the approval of the HealthPlan Services
stockholders except that no amendment will be made following approval and
adoption of the merger agreement by HealthPlan Services stockholders if the
amendment would require further stockholder approval under applicable law,
unless the further approval has already been obtained.

VOTING AGREEMENTS

     On October 5, 1999, concurrently with entering into the merger agreement,
UICI entered into voting agreements with Automatic Data Processing, Inc., James
K. Murray, Jr., William L. Bennett, Robert R. Parker, Shinnston Enterprises,
Ltd. and Elm Grove Associates Inc. The voting agreements were entered into by
each of these stockholders as an inducement to UICI to enter into the merger
agreement.

     Pursuant to the voting agreements, the stockholders agreed, among other
things, subject to specified conditions set forth in the voting agreements,
during the term of the voting agreements, to vote an aggregate of 2,441,499 HPS
Common Shares (constituting 17.87% of the HPS Common Shares issued and
outstanding on October 5, 1999) (a) in favor of the approval and adoption of the
merger agreement and the merger at every meeting of the stockholders of
HealthPlan Services at which such matters are considered and at every
adjournment of such meeting, and (b) against any other acquisition or proposed
acquisition of HealthPlan Services (whether by way of merger, purchase of
capital stock, purchase of assets or otherwise). The stockholders agreed to
deliver to UICI upon request immediately prior to any such vote a proxy
substantially in the form attached to the voting agreements. This stockholder
proxy is irrevocable during the term

                                      -59-
<PAGE>

of the voting agreements to the extent permitted under Delaware law and is
subject to the conditions set forth in the voting agreements.

     Pursuant to the voting agreements, during the term of the voting
agreements, the stockholders also agreed not to sell, assign, pledge, transfer
or otherwise dispose of, or grant any proxies with respect to any of the voting
agreement shares.

     In addition, the stockholders agreed that they will not deposit any of the
voting agreement shares in a voting trust or subject any of these shares to any
arrangement inconsistent with the voting agreement.

     The voting agreements terminate upon the earliest to occur of the effective
time of the merger or the date on which the merger agreement is terminated in
accordance with its terms.

     This summary of the voting agreements is qualified in its entirety by the
text of the voting agreements, the form of which is Exhibit A to the Agreement
and Plan of Merger attached as Appendix A to this proxy statement and
incorporated herein by reference.

OPTION AGREEMENT

     In connection with the merger agreement, UICI and HealthPlan Services
entered into an option agreement granting UICI an irrevocable option to purchase
up to 1,500,000 shares of HealthPlan Services common stock at an exercise price
of $7.375 per share. The option is exercisable if and when the merger agreement
is terminated and a termination fee is payable by HealthPlan Services as
described above under "TERMINATION AND TERMINATION FEES."

     The option agreement also grants UICI the right to have any shares of
HealthPlan Services acquired upon exercise of the option registered under the
Securities Act of 1933 for sale in a public offering.

     This summary of the option agreement is qualified in its entirety by the
text of the option agreement, which is attached as Appendix B to this proxy
statement and incorporated by reference.

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following unaudited pro forma combined financial statements give effect
to the merger using the purchase method of accounting. Under the purchase
method, the fair value of the acquired net tangible assets is recorded by UICI
as of the date on which the acquisition is consummated. These unaudited pro
forma combined financial statements should be read in conjunction with the
historical financial statements and related notes of UICI and HealthPlan
Services which are incorporated by reference in this

                                      -60-
<PAGE>

proxy statement/prospectus. See "WHERE YOU CAN FIND MORE INFORMATION" on page
77.

     The unaudited pro forma combined balance sheet at June 30, 1999 assumes the
merger had been completed on June 30, 1999. The unaudited pro forma combined
statements of income for the six month period ended June 30, 1999 and for the
year ended December 31, 1998 assume the merger had been completed on January 1,
1998, the beginning of the earliest period presented.

           The unaudited pro forma combined financial statements do not
necessarily indicate what UICI's financial position or operating results would
have been if the merger had been completed on the assumed completion dates and
they do not necessarily indicate future operating results of UICI.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

(a)      Adjustment reflects additional goodwill amortization expense ($720,000
         and $1,440,000 for the six and twelve month periods ending June 30,
         1999 and December 31, 1998, respectively) associated with additional
         goodwill recorded in connection with the merger. Approximately $36
         million of additional goodwill would have been recorded, which
         represents the amount of the excess of the HealthPlan Services' equity
         purchase price ($127.5 million) over the estimated fair value of the
         net assets acquired ($91.5 million). For purposes of the pro forma
         financial statements, the equity purchase price of $127.5 million has
         been estimated assuming (i) the issuance of 4,635,000 shares of UICI
         common stock in the merger at an assumed issuance price of $26.00 per
         share, and (ii) the capitalization of approximately $7.0 million of
         acquisition-related expenses. The goodwill recorded in connection with
         the merger will be amortized over 25 years.

(b)      Adjustment reflects (i) the elimination of the amortization of
         HealthPlan Services' capitalized debt issuance costs ($ 109,000 and
         $164,000 for the six and twelve month periods ended June 30, 1999 and
         December 31, 1998, respectively) and (ii) amortization ($375,000 and
         $750,000 for the six and twelve month periods ended June 30, 1999 and
         December 31, 1998 respectively), of capitalized debt issuance costs
         ($3.7 million) related to the refinancing of existing bank
         indebtedness.

(c)      Adjustment reflects the tax effects of pro forma adjustments at a 39%
         effective tax rate.

(d)      Adjustment reflects (i) payments of acquisition-related expenses
         (estimated to be $7.0 million) and (ii) payment of expenses related to
         refinancing of existing indebtedness (estimated to be approximately
         $3.7 million).

(e)      Reflects additional goodwill recorded in connection with the merger in
         the amount of $36 million in the aggregate, represented by (i) the
         amount of the excess of the HealthPlan Services equity purchase price
         ($127.5 million) over the estimated fair value of net assets acquired
         ($ 91.5 million) assuming the transaction had closed at June 30, 1999.
         For purposes of the pro forma financial statements, the equity purchase
         price of $127.5 million has been estimated assuming (i) the issuance of
         4,635,000 shares of UICI common stock in the merger at an assumed
         issuance price of $26.00 per share, and (ii) the capitalization of
         approximately $7.0 million of acquisition-related expenses. The
         goodwill recorded in connection with the merger will be amortized over
         25 years.

(f)      Reflects adjustment for (i) the write-off of the unamortized portion of
         capitalized debt issuance costs in the amount of $840,000, net of taxes
         of $328,000, and (ii) capitalization of debt issuance costs related to
         the refinancing of existing bank indebtedness in the amount of $3.7
         million, assuming the transaction had occurred at June 30, 1999.

(g)      Reflects adjustment for (i) cancellation of HealthPlan Services' equity
         accounts and (ii) estimated issuance of 4,635,000 shares of UICI common
         stock in the merger.

                        DESCRIPTION OF UICI COMMON SHARES

GENERAL

     UICI's charter provides for two classes of capital stock: UICI common
shares (100,000,000 shares authorized, of which 46,396,276 shares were
outstanding as of October 5, 1999); and UICI preferred shares (10,000,000 shares
authorized, none of which were outstanding as of October 5, 1999). The preferred
stock may be issued from time to time in such series and with such designations,
dividend rates and times of payment, redemption prices, and liquidation prices
or preferences as to assets in voluntary liquidation as the UICI Board of
Directors deems appropriate. Cumulative dividends, redemption provisions and
sinking fund requirements, to the extent that some or all of these features are
or may be present when the preferred stock is issued, could have an adverse
effect on the availability of earnings for distribution to the holders of UICI
common stock or for other corporate purposes.

           The statements below are summaries of certain provisions of the
charter of UICI. These summaries are not complete. UICI has filed its charter
with its SEC filings. See "WHERE YOU CAN FIND MORE INFORMATION" on page 77. The
rights of holders of common stock of UICI could also be impacted by UICI's
bylaws and the Delaware General Corporation Law. For summaries of relevant
provisions of the bylaws and Delaware law, see "COMPARATIVE RIGHTS OF HEALTHPLAN
SERVICES CORPORATION STOCKHOLDERS AND UICI STOCKHOLDERS" and "CERTAIN
ANTITAKEOVER EFFECTS OF CERTAIN UICI CHARTER AND BYLAWS PROVISIONS."

                                      -69-
<PAGE>

DIVIDEND RIGHTS

     Before any dividends are paid on the UICI common stock, the holders of any
preferred stock that may be issued will be entitled to receive their dividends
at the rates provided for the shares of their series. Any dividends that may be
declared on the common stock will be paid in an equal amount for each share of
common stock. UICI has not paid cash dividends on the common stock to date. UICI
currently intends to retain all future earnings to finance continued expansion
and operation of its business and subsidiaries. UICI's credit facility restricts
the payment of cash dividends unless specified earnings tests are satisfied.
Additional restrictions on the payment of cash dividends may be imposed in
connection with future issuances of preferred stock and indebtedness by UICI.
Any decisions as to the payment of cash dividends will be made by the UICI Board
in light of then current conditions, including earnings, operations, capital
requirements, liquidity, financial condition, restrictions in financing
arrangements and any other relevant factors as determined by the Board.

VOTING RIGHTS

     Each outstanding share of common stock is entitled to one vote per share on
each matter submitted to a vote of the stockholders. The affirmative vote of a
majority of the common stock present in person or by proxy and entitled to vote
is required to approve any act or action requiring a vote of the common
stockholders. Holders of common stock do not have cumulative voting rights. As a
result, the holders of a majority of the shares of common stock can elect all
the directors, and the holders of the remaining shares will not be able to elect
any directors.

LIQUIDATION RIGHTS

     Upon the liquidation, dissolution or winding up of UICI, after payment of
creditors and any liquidation preference of preferred stock that may be issued,
the remaining net assets of UICI will be distributed pro rata to the holders of
the common stock.

PREEMPTIVE AND SUBSCRIPTION RIGHTS

     No stockholder has the preemptive right to purchase or subscribe for any
additional capital stock. There are no conversion rights or redemption or
sinking fund provisions for the common stock. There is no liability to further
calls or assessments by UICI.

              COMPARATIVE RIGHTS OF HEALTHPLAN SERVICES CORPORATION
                       STOCKHOLDERS AND UICI STOCKHOLDERS

     When we complete the merger, HealthPlan Services stockholders will become
stockholders of UICI and their rights will be governed by the UICI certificate
of incorporation and the UICI bylaws, which differ in certain material respects
from the HealthPlan Services certificate of incorporation and the HealthPlan
Services bylaws. As stockholders of UICI, the rights of former HealthPlan
Services stockholders will continue to be governed by the Delaware Business
Corporation Law (the "DELAWARE LAW").

                                      -70-
<PAGE>

     The following comparison of the UICI charter and bylaws, on the one hand,
and the HealthPlan Services' charter and bylaws, on the other hand, summarizes
the material differences but is not intended to list all differences.

BUSINESS COMBINATIONS

     The Delaware Law provides that a merger or consolidation may be approved by
a majority vote of the shares entitled to vote thereon, unless a greater
percentage is required by the corporation's certificate of incorporation. Under
both UICI's and HealthPlan Services' charters, the vote of a majority of the
stockholders is sufficient to approve a merger or consolidation.

STATE TAKEOVER LEGISLATION

     Section 203 of the Delaware Law, in general, prohibits a stockholder who
acquires more than 15% of the outstanding voting shares of a corporation subject
to the statute, but less than 85% of such shares, from engaging in specified
"business combinations" with the corporation for three years after the date that
the stockholder became an interested stockholder. Section 203 does not apply if
(1) before the acquisition date the corporation's board of directors has
approved either the business combination or the transaction in which the
stockholder became an interested stockholder or (2) the corporation's board of
directors approves the business combination and at least two-thirds of the
outstanding voting stock of the corporation not owned by the interested
stockholder vote to authorize the business combination. The term "business
combination" encompasses a wide variety of transactions with or caused by an
interested stockholder in which the interested stockholder receives or could
receive a benefit on other than a pro rata basis with other stockholders,
including mergers, specified asset sales, specified issuances of additional
shares to the interested stockholder, transactions with the corporation that
increase the proportionate interest of the interested stockholder or
transactions in which the interested stockholder receives certain other
benefits. Neither UICI nor HealthPlan Services has "opted out" of Section 203,
as is permitted under the Delaware Law.

RIGHTS OF DISSENTING STOCKHOLDERS

           Under the Delaware Law, dissenting stockholders have rights of
appraisal in connection with certain mergers or consolidations. Unless a
corporation's certificate of incorporation otherwise provides, the Delaware Law
does not provide appraisal rights (1) for shares listed on a national securities
exchange or designated as a national market system security on an interdealer
quotation system by the National Association of Securities Dealers, Inc. or held
of record by more than 2,000 stockholders (as long as the stockholders receive
in the merger shares of the surviving corporation or of any other corporation
the shares of which are listed on a national securities exchange or designated
as a national market system security on an interdealer quotation system by the
National Association of Securities Dealers, Inc. or held of record by more than
2,000 stockholders) or (2) if the corporation is the surviving corporation and
no vote of its stockholders is required for the merger. Neither UICI's nor
HealthPlan Services' certificate of incorporation provides otherwise. The
Delaware Law does not provide appraisal rights to stockholders who dissent from
the sale of all or substantially all of a corporation's assets or an amendment
to the corporation's certificate of incorporation, unless the corporation's

                                      -71-
<PAGE>

certificate of incorporation provides for dissenters' rights in those cases.
Neither UICI's nor HealthPlan Services' charter so provides.

AMENDMENTS TO CHARTERS

     The Delaware Law provides that the certificate of incorporation of a
corporation may be amended upon the affirmative vote of a majority of the
outstanding shares of each class entitled to vote thereon, unless the
corporation's charter requires a larger percentage. UICI's and HealthPlan
Services' charters allow for amendments to the charters as prescribed by
Delaware Law.

AMENDMENTS TO BYLAWS

     Under the Delaware Law, holders of a majority of the voting power of a
corporation and, when provided in the certificate of incorporation, the
directors of the corporation, have the power to adopt, amend and repeal the
bylaws of a corporation. HealthPlan Services' charter grants the HealthPlan
Services Board this power. UICI's charter grants the UICI board this power, but
provides that any adoption, amendment, or repeal of the bylaws by the UICI board
may be repealed or changed by a majority of the voting power of UICI.

STOCKHOLDER ACTION

     The Delaware Law permits actions which could be taken at a stockholders'
meeting to be taken by written action of the stockholders unless the
corporation's charter or bylaws require that a meeting be held. Neither UICI's
nor HealthPlan Services' charter requires stockholders to act at a meeting.

SPECIAL MEETINGS OF STOCKHOLDERS

     The Delaware Law provides that special meetings of stockholders may be
called by a corporation's board of directors and other persons authorized by the
corporation's certificate of incorporation or bylaws. HealthPlan Services'
bylaws provide that special meetings of stockholders may be called only by the
chairman of the board, chief executive officer, the Board or by a majority of
the shares entitled to vote at the meeting. UICI's charter and bylaws authorize
only the Chairman of the Board, the President, the Board of Directors or the
holders of not less than one-tenth of all shares entitled to vote at the meeting
to call a special meeting.

CUMULATIVE VOTING

     The Delaware Law permits a corporation's certificate of incorporation to
provide for cumulative voting in the election of directors. HealthPlan Services'
charter does not provide for cumulative voting. UICI's charter expressly
prohibits cumulative voting.

                                      -72-
<PAGE>

NUMBER AND ELECTION OF DIRECTORS

     UICI's charter and bylaws provide that the board of directors will include
initially five directors, with a change in the number to be made by a resolution
of the board, but never less than one director.

     HealthPlan Services' bylaws provide for an initial board of two directors,
with changes in the number of directors to be made by resolution of the board or
stockholders.

REMOVAL OF DIRECTORS

     The Delaware Law provides that unless a corporation's certificate of
incorporation otherwise provides, directors may be removed with or without cause
and requires that the removal of directors be approved by a majority vote of the
shares then entitled to vote at an election of directors. HealthPlan Services'
charter provides that a member of the HealthPlan Services Board may be removed
with or without cause only at a special meeting of stockholders called for that
purpose. UICI's charter does not otherwise discuss the removal of directors.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Delaware Law permits indemnification of officers and directors against
liabilities and expenses incurred in proceedings if the person acted in good
faith and in a manner he or she reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action,
had no reasonable cause to believe such person's conduct was unlawful. In the
case of derivative actions, indemnification is limited to expenses and no
indemnification may be made in respect of any claim, issue or matter as to which
such person has been adjudged to be liable to the corporation unless
indemnification is otherwise authorized by a court. UICI's and HealthPlan
Services' bylaws require the companies to indemnify officers and directors to
the full extent permitted by law.

LIMITATION OF PERSONAL LIABILITY OF DIRECTORS

     The Delaware Law allows a Delaware corporation to include in its
certificate of incorporation, and HealthPlan Services' and UICI's charters
contain, a provision eliminating the liability of a director for monetary
damages for a breach of such director's fiduciary duties as a director, except
liability for any breach of the director's duty of loyalty to the corporation's
stockholders, for acts or omissions not in good faith or that involve
intentional misconduct or knowing violation of law, under Section 174 of the
Delaware Law (which deals generally with unlawful payments of dividends, stock
repurchases and redemptions), and for any transaction from which the director
derived an improper personal benefit.

                         CERTAIN ANTITAKEOVER EFFECTS OF
                      CERTAIN CHARTER AND BYLAWS PROVISIONS

GENERAL

     UICI's charter contains provisions that will make more difficult the
acquisition of control of the company by means of a tender offer, open market
purchases, a proxy fight or otherwise that are not approved by the company's
board of directors. UICI's bylaws also contain provisions that could have an
antitakeover effect.

     The purposes of such charter and bylaw provisions are to discourage certain
types of transactions, described below, which may involve an actual or
threatened change of control and to encourage persons seeking to acquire control
to negotiate the terms of any proposed business combination or offer with the
board of directors. The provisions are designed to reduce vulnerability to an
unsolicited proposal for a takeover that does not contemplate the acquisition of
all outstanding shares or is otherwise unfair to stockholders, or an unsolicited
proposal for the restructuring or sale of all or part of the company. UICI
believes that, as a general rule, such proposals would not be in the best
interests of stockholders. These provisions will help ensure that the UICI board
of directors, if confronted by a surprise proposal from a third party which has
acquired a block of stock, will have sufficient time to review the proposal and
appropriate alternatives to the proposal and to act in what it believes to be
the best interests of stockholders.

     UICI believes that the provisions discussed below may provide some measure
of protection for stockholders against certain potentially coercive takeover
tactics. Such takeover tactics include the accumulation of substantial stock
positions in public companies by third parties as a prelude to proposing a
takeover, a restructuring or a sale of all or part of the company or another
similar extraordinary corporate action. Such actions are often undertaken by a
third party without advance notice to, or consultation with, the management or
board of directors of a company. In many cases, the purchaser seeks
representation on a company's board of directors in order to increase the
likelihood that its proposal will be implemented by a company. If a company
resists the efforts of the purchaser to obtain representation on the company's
board, a purchaser may commence a proxy contest to have its nominees elected to
the board of directors in place of certain directors or in place of the entire
board of directors.

     UICI believes that the imminent threat of removal of management or the
board of directors in such situations would severely curtail the ability of
management or the board of directors to negotiate effectively with such
purchasers. Management or the board of directors would be deprived of the time
and information necessary to evaluate the takeover proposal, to study
alternative proposals and to help ensure that the best price is obtained in any
transaction involving the company which may ultimately be undertaken.

     These provisions, individually and collectively, will make difficult and
may discourage a merger, tender offer or proxy fight, even if such transaction
or occurrence may be favorable to the interests of stockholders, and may delay
or frustrate the assumption of control by a holder of a large block of common
stock and the removal of incumbent management, even if such removal might be
beneficial to stockholders. Furthermore, these provisions may deter or could be
used to

                                      -74-
<PAGE>

frustrate a future takeover attempt which is not approved by the incumbent board
of directors, but which the holders of a majority of the shares may deem to be
in their best interests or in which stockholders may receive a substantial
premium for their stock over prevailing market prices of such stock. By
discouraging takeover attempts, these provisions might have the incidental
effect of inhibiting certain changes in management (some or all of the members
of which might be replaced in the course of a change of control) and also the
temporary fluctuations in the market price of the stock which often result from
actual or rumored takeover attempts.

     Set forth below is a description of the possible antitakeover effects of
such provisions.

PREFERRED STOCK

     UICI's bylaws authorize the board to establish series of preferred stock.
The UICI Board has the authority to fix the rights and preferences of each such
series with respect to, among other things, the dividend rate, redemption
provisions, liquidation preferences, conversion rights and voting rights. The
number of authorized shares of preferred stock is 10,000,000. As of the date of
this proxy statement/prospectus, no UICI Preferred Shares are outstanding.

     We believe that the availability of such preferred stock will provide
increased flexibility in structuring possible future financings and
acquisitions, and in meeting other corporate needs which might arise. Having
such authorized shares available for issuance will allow the company to issue
shares of preferred stock in certain cases without the expense and delay of a
special meeting of stockholders. Subject to the possible rights of holders of
any outstanding shares of preferred stock to vote on such issuances, the
authorized shares of preferred stock, as well as shares of common stock, will be
available for issuance without further action by stockholders, unless such
action is required by applicable law or the rules of any stock exchange on which
the securities may be listed. Although there is no intention at the present time
of doing so, the board could authorize a series of preferred stock that could
impede a business combination through adoption of a stockholder rights plan. The
board will make any determination to issue such shares based on its judgment as
to the best interests of the company and its then existing stockholders. The
board, in so acting and upon obtaining any required regulatory approvals, could
issue preferred stock having terms which could discourage an acquisition attempt
or other transaction that some, or a majority, of the stockholders might believe
to be in their best interests or in which stockholders might receive a premium
for their stock over the then market price of such stock.

COMMON STOCK

     UICI's charter presently authorizes the issuance of 100 million UICI common
shares, approximately 51 million of which would have been outstanding after the
merger if it had occurred on October 5, 1999.

     The board would have the ability, in the event of a proposed merger, tender
offer or other attempt to gain control of the company that was not approved by
the board, to issue additional common stock that would dilute the stock
ownership of the acquiror.

                                      -75-
<PAGE>

ANTITAKEOVER LEGISLATION

     We have described certain antitakeover provisions of the Delaware Law under
"COMPARATIVE RIGHTS OF HEALTHPLAN SERVICES STOCKHOLDERS AND UICI STOCKHOLDERS -
STATE TAKEOVER LEGISLATION."

     The Delaware Law provisions should encourage persons interested in
acquiring control to negotiate in advance with the board, since the restrictions
contained in the provisions regarding business combinations with interested
stockholders do not apply if the acquiror first obtains disinterested director
approval. As stated above, in the event of a proposed acquisition of control, we
believe that the interests of stockholders will best be served by a transaction
that results from negotiations based upon careful consideration of the proposed
terms, such as the price to be paid to minority stockholders, the form of
consideration paid and tax effects of the transaction. The antitakeover
provisions of the Delaware Law should also tend to discourage the accumulation
of large blocks of stock by third parties, which we believe can be disruptive to
the stability of important relationships with employees, customers and major
lenders.

     The antitakeover provisions of the Delaware Law will not prevent a hostile
takeover. They may, however, make more difficult or discourage a takeover or the
acquisition of control by a principal stockholder and thus the removal of
incumbent management. Some stockholders may find this disadvantageous in that
they may not be afforded the opportunity to participate in takeovers which are
not approved by the board, but in which they might receive, for at least some of
their shares, a substantial premium above the market price at the time of a
tender offer or other acquisition transaction. The Delaware antitakeover
provisions should not prevent or discourage transactions in which an acquiring

      STOCKHOLDER PROPOSALS FOR THE 2000 HEALTHPLAN SERVICES ANNUAL MEETING

the merger is not completed before the time of such meeting. In the event that
such a meeting is held, any proposals of stockholders intended to be presented
at the 2000 annual meeting of stockholders must have been received by the

2000 proxy statement, but is instead sought to be presented directly at the 2000
annual meeting, management will be able to vote proxies in its discretion if
HealthPlan Services: (i) does not receive notice of the proposal prior to the
close of business on February 21, 2000; or (ii) receives notice of the proposal
before the close of business on February 21, 2000 and advises stockholders in
the 2000 proxy statement about the nature of the matter and how management
intends to vote on such matter.

     Stockholder proposals should be sent certified mail, return receipt
requested, to the attention of the Corporate Secretary at the Company's
principal executive offices of HealthPlan Services at 3501 Frontage Road, Tampa,

Section 3.1(b)), shall be converted into the right to receive a number of shares
of Common Stock, par value $.01 per share (the "Parent Common Stock"), of
Parent, equal to the Exchange Ratio (as hereinafter defined) and payable upon
the surrender of the certificate formerly representing such share of Company
Common Stock in accordance with Section 3.2 hereof. The "Exchange Ratio" shall
be equal to the result (rounded to the nearest 1/10,000, with .0005 rounded up)
obtained by dividing $9.50 by: (i) $28.00, if the Parent Average Price (as
hereinafter defined) is less than $28.00 and greater than or equal to $23.00;
(ii) the Parent Average Price plus $5.00, if the

                                      A-2
<PAGE>

Parent Average Price is less than $23.00 and greater than or equal to $21.00;
(iii) the Parent Average Price, if the Parent Average Price is greater than or
equal to $28.00 and less than or equal to $30.00; (iv) $30.00, if the Parent
Average Price is greater than $30.00 and less than or equal to $33.00; and (v)
the Parent Average Price less $3.00, if the Parent Average Price is greater than
$33.00; PROVIDED, HOWEVER, that if the Parent Average Price is less than $21.00,
the Exchange Ratio shall be .3654. "Parent Average Price" means the average
(rounded to the nearest 1/10,000th) of the volume weighted averages (rounded to
the nearest 1/10,000th) of the trading prices of the Parent Common Stock on the
New York Stock Exchange (the "NYSE"), as reported by Bloomberg Financial Markets
(or such other source Parent and the Company shall agree in writing), for the 20
consecutive trading days ending on the third trading day immediately preceding
the Effective Time.

     (b) All shares of Company Common Stock that, in either case, are (i) held
by the Company as treasury shares or (ii) owned by Parent or any wholly-owned
Subsidiary of Parent, shall be canceled and retired and cease to exist, and no
securities of Parent or other consideration shall be delivered in exchange
therefor. As used in this Agreement, the term "Subsidiary" means, with respect
to any party, any corporation or other organization, whether incorporated or
unincorporated, of which (x) such party or any other Subsidiary of such party is
a general partner (excluding partnerships, the general partnership interests of
which held by such party or any Subsidiary of such party do not have a majority
of the voting interest in such partnership) or (y) at least a majority of the
securities or other interests having by their terms ordinary voting power to
elect a majority of the board of directors or others performing similar
functions with respect to such corporation or other organization is directly or
indirectly owned or controlled by such party and/or one or more of its
Subsidiaries.

     (c) All shares of Common Stock, $.01 par value per share ("Sub Common
Stock"), of Sub issued and outstanding immediately prior to the Effective Time
shall be converted into and become one fully paid and nonassessable share of
Common Stock, par value $.01 per share, of the Surviving Corporation.

     (d) Each outstanding option to purchase Company Common Stock (each, a
"Company Stock Option") shall be assumed by Parent as more specifically provided
in Section 7.8.

     SECTION 3.2. EXCHANGE OF COMPANY COMMON STOCK; PROCEDURES.

     (a) Prior to the Closing Date, Parent shall designate a bank or trust
company reasonably acceptable to the Company to act as Exchange Agent hereunder
(the "Exchange Agent"). As soon as practicable after the Effective Time, Parent
shall deposit with or for the account of the Exchange Agent stock certificates
representing the aggregate number of shares of Parent Common Stock issuable
pursuant to Section 3.1 in exchange for outstanding shares of Company Common
Stock, which shares of Parent Common Stock shall be deemed to have been issued
at the Effective Time.

     (b) As soon as practicable after the Effective Time, Parent shall cause the
Exchange Agent to mail to each holder of record of a certificate or certificates
which immediately prior to the Effective Time represented outstanding shares of
Company Common Stock (the "Certificates") that were converted pursuant to
Section 3.1 into the right to receive shares of

                                       A-3

 <PAGE>

Parent Common Stock (i) a form of letter of transmittal specifying that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent and (ii)
instructions for use in surrendering such Certificates in exchange for
certificates representing shares of Parent Common Stock. Upon surrender of a
Certificate for cancellation to the Exchange Agent, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor (x) a certificate representing that number of whole
shares of Parent Common Stock which such holder has the right to receive
pursuant to the provisions of this Article III, (y) cash in lieu of any
fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 3.4, after giving effect to any required tax withholdings,
and the Certificate so surrendered shall forthwith be canceled and (z) any
dividends or distributions to which such holder may be entitled pursuant to
Section 3.3. In the event of a transfer of ownership of Company Common Stock
which is not registered in the transfer records of the Company, a certificate
representing the proper number of shares of Parent Common Stock may be issued to
a transferee if the Certificate representing such Company Common Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer, and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
3.2(b), each Certificate shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender a certificate
representing shares of Parent Common Stock, cash in lieu of any fractional
shares of Parent Common Stock and any dividends or distributions, which may be
payable pursuant to Section 3.3 hereof.

     SECTION 3.3. DIVIDENDS; ESCHEAT. No dividends or distributions that are
declared on shares of Parent Common Stock will be paid to persons entitled to
receive certificates representing shares of Parent Common Stock until such
persons surrender their Certificates. Upon such surrender, there shall be paid
to the person in whose name the certificates representing such shares of Parent
Common Stock shall be issued, any dividends or distributions with respect to
such shares of Parent Common Stock which have a record date on or after the
Effective Time and shall have become payable between the Effective Time and the
time of such surrender. In no event shall the person entitled to receive such
dividends or distributions be entitled to receive interest thereon. Promptly
following the date which is six months after the Effective Time, the Exchange
Agent shall deliver to the Surviving Corporation all cash, certificates and
other documents in its possession relating to the transactions described in this
Agreement, and any holders of Company Common Stock who have not theretofore
complied with this Article III shall look thereafter only to the Surviving
Corporation for the shares of Parent Common Stock, any dividends or
distributions thereon, and any cash in lieu of fractional shares thereof to
which they are entitled pursuant to this Article III. Notwithstanding the
foregoing, neither the Exchange Agent nor any party hereto shall be liable to a
holder of Company Common Stock for any shares of Parent Common Stock, any
dividends or distributions thereon or any cash in lieu of fractional shares
thereof delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.

     SECTION 3.4. NO FRACTIONAL SECURITIES. No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional interests shall not
entitle the owner thereof to vote or to any rights of a security holder. In lieu
of any such fractional securities, each holder of Company Common

                                      A-4
<PAGE>

Stock who would otherwise have been entitled to a fraction of a share of Parent
Common Stock upon surrender of such holder's Certificates will be entitled to
receive a cash payment (without interest) determined by multiplying (i) the
fractional interest to which such holder would otherwise be entitled (after
taking into account all shares of Company Common Stock then held of record by
such holder) and (ii) the average of the per share closing prices for Parent
Common Stock on the NYSE for the five trading days immediately preceding the
Effective Time.

     SECTION 3.5. CLOSING OF COMPANY TRANSFER BOOKS. At the Effective Time, the
stock transfer books of the Company shall be closed and no transfer of shares of
Company Common Stock shall thereafter be made. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged as provided in this Article III.

     SECTION 3.6. FURTHER ASSURANCES. If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of Sub or the Company acquired or to be acquired
by the Surviving Corporation as a result of, or in connection with, the Merger
or otherwise to carry out this Agreement, the officers of the Surviving
Corporation shall be authorized to execute and deliver, in the name and on
behalf of each of Sub and the Company or otherwise, all such deeds, bills of
sale, assignments and assurances and to take and do, in such names and on such
behalves or otherwise, all such other actions and things as may be necessary or
desirable to vest, perfect or confirm any and all right, title and interest in,
to and under such rights, properties or assets in the Surviving Corporation or
otherwise to carry out the purposes of this Agreement.

                                  ARTICLE IV.
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent and Sub as follows:

     SECTION 4.1. CORPORATE ORGANIZATION; RELATED ENTITIES.

     (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware and has the corporate
power and authority to own or lease its properties and to carry on its business
as it is presently being conducted. Schedule 4.1(a) lists, and the Company is
duly qualified as a foreign corporation to do business and is in good standing
in, every jurisdiction where the character of the Company's properties (owned or
leased) or the nature of its activities makes such qualification necessary,
except for failures, if any, to be so qualified which would not in the aggregate
have a Company Material Adverse Effect (as hereinafter defined).

     (b) Schedule 4.1(b) lists all of the Subsidiaries of the Company which
would be required to be set forth as an exhibit to the Company's Annual Report
on Form 10-K pursuant to the rules and regulations under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (the "Company Subsidiaries"). Each
Subsidiary of the Company is a corporation duly organized, validly existing and
in good standing under the laws of its jurisdiction of organization or
incorporation and has the corporate power and authority to own or lease its
properties and to

                                      A-5
<PAGE>

carry on its business as it is presently being conducted, except for failures,
if any, to be so organized, validly existing or in good standing or to have such
corporate power and authority which would not in the aggregate have a Company
Material Adverse Effect.

     (c) The copies of the Certificate of Incorporation and By-Laws of the
Company heretofore delivered to Parent are complete and correct copies of such
instruments as presently in effect.

     (d) As used in this Agreement, any reference to any event, change,
circumstance or effect having a "Company Material Adverse Effect" shall mean
that such event, change, circumstance or effect is, individually or in the
aggregate, materially adverse to the business, operations, properties, assets
(including intangible assets), liabilities (including contingent liabilities),
condition (financial or other) or results of operations of the Company and any
of its Subsidiaries taken as a whole or to the ability of the Company to
consummate the Merger and the other transactions contemplated by this Agreement,
other than any event, change, circumstance or effect relating to or resulting
from: (i) general changes in the industries in which the Company operates its
business; (ii) changes in general economic conditions or securities markets in
general; and (iii) the termination of any contract listed in Schedule 4.4
resulting from a termination right triggered by this Agreement, the transactions
contemplated hereby or the announcement thereof.

     SECTION 4.2. CAPITALIZATION.

     (a) As of the date of this Agreement, the authorized capital stock of the
Company consists of 100,000,000 shares of Company Common Stock, 13,665,139 of

outstanding under all of the Company Option Plans (as defined below) and

HealthPlan Services Corporation 1995 Incentive Equity Plan, the HealthPlan
Services Corporation 1995 Consultants Stock Option Plan, the HealthPlan Services
Corporation 1996 Employee Stock Purchase Plan, the HealthPlan Services
Corporation 1995 Directors Stock Option Plan and the Amended and Restated
HealthPlan Services Corporation Directors Equity Plan. All of the issued and
outstanding shares of Company Common Stock are validly issued, fully paid and
nonassessable.

     (b) Except as disclosed in this Section 4.2 or on Schedule 4.2(b) or as
contemplated by the Option Agreement (defined herein), (i) there is no
outstanding right, subscription, warrant, call, unsatisfied preemptive right,
option or other agreement or arrangement of any kind to purchase or otherwise to
receive from the Company any of the outstanding authorized but unissued or
treasury shares of the capital stock or any other security of the Company, (ii)
there is no outstanding security of any kind convertible into or exchangeable
for such capital stock, and (iii) there is no voting trust or other agreement or

                                      A-6
<PAGE>

     (c) Except as set forth on Schedule 4.2(c), none of the awards, grants or
other agreements pursuant to which Company Stock Options were issued have
provisions which accelerate the vesting or right to exercise such options upon
the execution of this Agreement (including the documents attached as Exhibits
hereto), the consummation of the transactions contemplated hereby (or thereby)
or any other "change of control" or similar events.

     (d) Except as set forth on Schedule 4.2(d) and for qualifying shares
required by certain foreign jurisdictions, all of the issued and outstanding
capital stock of each of the Company Subsidiaries has been validly issued, is
fully paid and nonassessable and is owned of record and beneficially, directly
or indirectly, by the Company or another Subsidiary of the Company, free of any
Liens, preemptive rights or other restrictions with respect thereto.

     SECTION 4.3. AUTHORITY RELATIVE TO THIS AGREEMENT. The Company has the
requisite corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated on its part hereby have been duly authorized by
the Company's Board of Directors and, except for the approval of its
stockholders to be sought at the stockholders meeting contemplated by Section
7.4(a) with respect to this Agreement, no other corporate proceedings on the
part of the Company are necessary to authorize this Agreement or for the Company
to consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by the Company and constitutes a valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms except to the extent that enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
affecting the enforcement of creditors' rights generally or by general equitable
principles.

     SECTION 4.4. CONSENTS AND APPROVALS; NO VIOLATIONS. Neither the execution,
delivery and performance of this Agreement by the Company, nor the consummation
by the Company of the transactions contemplated hereby, will (i) conflict with
or result in any breach of any provisions of the charter, By-laws or other
organizational documents of the Company or the organizational documents of any
of its Subsidiaries, (ii) require a filing with, or a permit, authorization,
consent or approval of, any federal, state, local or foreign court, arbitral
tribunal, administrative agency or commission or other governmental or other
regulatory authority or administrative agency or commission (a "Governmental
Entity"), except in connection with or in order to comply with the applicable
provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), for the filing of a registration statement on Form S-4
under the Securities Act of 1933, as amended (the "Securities Act") with respect
to Parent Common Stock to be offered to the Company stockholders, the filing of
the Proxy Statement-Prospectus under the Exchange Act, filings or approvals
required under state securities or "blue sky" laws, the By-Laws of the National
Association of Securities Dealers (the "NASD") and the filing and recordation of
a Certificate of Merger as required by the DGCL, (iii) except as set forth on
Schedule 4.4 hereto, result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, cancellation or acceleration) under, or result in the
creation of any mortgage, pledge, security interest, encumbrance, lien, claim or
charge of any kind or right of others of whatever nature ("Liens"), on any
property or asset of the Company or any of its Subsidiaries pursuant to, any of
the terms,


                                      A-7
<PAGE>

conditions or provisions of any material note, bond, mortgage, indenture, lease,
license, contract, agreement or other instrument or obligation (each, a
"Contract") to which the Company or any of its Subsidiaries is a party or by
which it or any of its properties or assets may be bound or (iv) violate any
law, order, writ, injunction, decree, statute, rule or regulation of any
Governmental Entity applicable to the Company or any of its Subsidiaries or any
of their properties or assets, except, in the case of clauses (ii), (iii) and
(iv), where failures to make such filing or obtain such authorization, consent
or approval would not have, or where such violations, breaches or defaults or
Liens would not have, in the aggregate, a Company Material Adverse Effect.

     SECTION 4.5. REPORTS AND FINANCIAL STATEMENTS. Except as set forth on
Schedule 4.5, the Company has timely filed all reports required to be filed by
the Company with the Securities and Exchange Commission (the "SEC") pursuant to
the Exchange Act or the Securities Act since December 31, 1997 (collectively,
the "Company SEC Reports"), and has previously made available to Parent true and
complete copies of all such Company SEC Reports. Such Company SEC Reports, as of
their respective dates, complied in all material respects with the applicable
requirements of the Securities Act and the Exchange Act, as the case may be, and
none of such Company SEC Reports, as of their respective dates, contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the Company SEC Reports have been prepared
in accordance with United States generally accepted accounting principles
("GAAP") consistently applied throughout the periods indicated (except as
otherwise noted therein or, in the case of unaudited statements, as permitted by
Form 10-Q of the SEC) and fairly present (subject, in the case of unaudited
statements, to normal recurring year-end adjustments and any other adjustments
described therein) the financial position of the Company as at the dates thereof
and the results of operations and cash flows of the Company for the periods then
ended. Since December 31, 1998, there has been no change in any of the
significant accounting (including tax accounting) policies, practices or
procedures of the Company.

     SECTION 4.6. ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set forth on
Schedule 4.6 or in the Company SEC Reports filed as of the date of this
Agreement, since December 31, 1998, (i) neither the Company nor any of its
Subsidiaries has conducted its business and operations other than in the
ordinary course of business and consistent with past practices or taken any
actions that, if it had been in effect, would have violated or been inconsistent
with the provisions of Section 6.1 and (ii) there has not been any fact, event,
circumstance or change affecting or relating to the Company or any of its
Subsidiaries which has had or is reasonably likely to have a Company Material
Adverse Effect. Except as set forth on Schedule 4.6 or as would not represent a
Company Material Adverse Effect, the transactions contemplated by this Agreement
will not constitute a change of control under or require the consent from or the
giving of notice to a third party pursuant to the terms, conditions or
provisions of any Contract to which the Company or any of its Subsidiaries is a
party.

     SECTION 4.7. LITIGATION. Except as disclosed on Schedule 4.7 and except for
litigation disclosed in the notes to the financial statements included in the
Company's Annual Report to Stockholders for the fiscal year ended December 31,
1998 or in the Company SEC Reports filed subsequent thereto, as of the date
hereof, there is no suit, action, proceeding or investigation


                                      A-8
<PAGE>

pending or, to the best knowledge of the Company, threatened against, the
Company or any of its Subsidiaries or with respect to which the Company or any
of its Subsidiaries could be required to provide indemnification or to otherwise
contribute to liabilities or damages relating thereto, the outcome of which
could reasonably be expected to have a Company Material Adverse Effect; nor is
there any judgment, decree, injunction, rule or order of any Governmental Entity
outstanding against the Company or any of its Subsidiaries having, or which,
insofar as can reasonably be foreseen, in the future may have a Company Material
Adverse Effect. For purposes of this Agreement, wherever the term "Company
knowledge" or "best knowledge of the Company" or any phrase of similar import is
used it shall mean the actual knowledge of the directors and the executive
officers of the Company, or knowledge which such persons could reasonably be
expected to possess in view of their respective positions with the Company, and,
except as provided above, shall not include imputed, constructive or implied
knowledge of any such persons.

     SECTION 4.8. ABSENCE OF UNDISCLOSED LIABILITIES. Except for liabilities or
obligations which are accrued or reserved against in the Company's financial
statements (or reflected in the notes thereto) included in the Company SEC
Reports or which were incurred after June 30, 1999 in the ordinary course of
business and consistent with past practice, or except as set forth on Schedule
4.8, none of the Company or any of its Subsidiaries has any liabilities or
obligations (whether absolute, accrued, contingent or otherwise) of a nature
required by GAAP to be reflected in a balance sheet (or reflected in the notes
thereto) and which could reasonably be expected to have a Company Material
Adverse Effect.

     SECTION 4.9. NO DEFAULT. Except as set forth in Schedule 4.9, neither the
Company nor any of its Subsidiaries is in breach or violation of, or in default
under (and no event has occurred which with notice or lapse of time or both
would constitute such a breach, violation or default), any term, condition or
provision of (i) the Company's or the respective Subsidiary's Certificate or
Articles of Incorporation or By-Laws, or (ii) (x) any order, writ, decree,
statute, rule or regulation of any Governmental Entity applicable to the Company
or any of its Subsidiaries or any of their properties or assets or (y) any
Contract to which the Company or any of its Subsidiaries is a party or by which
the Company, or any of its Subsidiaries or any of their properties or assets may
be bound, except in the case of this clause (ii), which breaches, violations or
defaults, individually or in the aggregate, would not have a Company Material
Adverse Effect. The Company and each of its Subsidiaries have, and are in
compliance with, all licenses, permits, variances, exemptions, orders, approvals
and other authorizations of all Governmental Entities as are necessary in order
to enable them to own their businesses and conduct their businesses as currently
conducted and as currently proposed to be conducted and to enter into the
transactions contemplated hereby, the lack of which, under applicable law, rule
or regulation, (x) would render legally impermissible the transactions
contemplated hereby or (y) could reasonably be expected to have a Company
Material Adverse Effect.

     SECTION 4.10. TAXES.

     (a) The Company has heretofore delivered or will make available to Parent
true, correct and complete copies of the federal, state, local and foreign
income, franchise sales and other Tax Returns (as hereinafter defined) filed by
the Company and each of its Subsidiaries for each of the Company's years ended
1996, 1997 and 1998, inclusive.


                                      A-9
<PAGE>

     (b) Except where the failure to be in compliance with any of the following
representations would not have a Company Material Adverse Effect or as disclosed
in Schedule 4.10(b):

         (i)   All returns, declarations, reports, estimates, statements,
               schedules or other information or document with respect to Taxes
               (as hereinafter defined) (collectively, "Tax Returns") required
               to be filed by the Company and each of its Subsidiaries have been
               timely filed (giving effect to extensions granted with respect
               thereto), and all such Tax Returns are true, correct and
               complete. The Company and each of its Subsidiaries is not
               required to file any state Tax Returns other than in the states
               reflected on Schedule 4.10(b), identifying for the Company and
               for each Subsidiary each such state. No authority in a
               jurisdiction where any of the Company or its Subsidiaries does
               not file Tax Returns has claimed that the Company or any of its
               Subsidiaries is subject to tax in such jurisdiction.

         (ii)  The Company and each of its Subsidiaries has timely paid all
               Taxes owed (whether or not shown on any Tax Return) or claimed to
               be due from it by any federal, state, local, foreign or other
               taxing authority.

         (iii) There are no liens for Taxes upon the assets of the Company or
               any of its Subsidiaries except Liens for Taxes not yet due and
               payable.

         (iv)  No Tax Returns of the Company or any of its Subsidiaries have
               been examined by the Internal Revenue Service (the "Service")
               since 1995. No deficiency for any Taxes has been proposed,
               asserted or assessed against the Company or any of its
               Subsidiaries which has not been resolved and paid in full. There
               are no outstanding waivers, extensions or comparable consents
               regarding the application of the statute of limitations with
               respect to any Taxes or Tax Returns that have been given by the
               Company or any of its Subsidiaries (including the time for filing
               of Tax Returns or paying Taxes).

         (v)   Neither the Company nor any of its Subsidiaries has made any
               change in accounting methods, received a ruling from any taxing
               authority or signed an agreement with any taxing authority.

         (vi)  The Company and each of its Subsidiaries has complied with all
               applicable laws, rules and regulations relating to the payment
               and withholding of Taxes (including, without limitation,
               withholding of Taxes pursuant to Sections 1441 and 1442 of the
               Code or similar provisions under any foreign laws) and has,
               within the time and the manner prescribed by law, withheld from
               employee wages and paid over to the proper governmental
               authorities all amounts required to be so withheld and paid over
               under applicable laws.


                                      A-10
<PAGE>

         (vii) Other than as set forth in Schedule 4.10(b)(vii), no audit or
               other proceeding by any federal, state, local or foreign court,
               governmental, regulatory, administrative or similar authority is
               presently pending with respect to any Taxes or Tax Return of the
               Company or any of its Subsidiaries, and neither the Company nor
               any of its Subsidiaries has received a written notice of any
               pending audits or proceedings. Schedule 4.10(b)(vii) shall set
               forth the nature of any such audit or proceeding, the type of Tax
               Return, any deficiencies proposed, asserted or assessed and the
               amount thereof and the tax year in question.

         (viii) Neither the Company nor any its Subsidiaries is a party to, is
               bound by or has any obligation under, any Tax sharing, allocation
               or indemnity agreement or similar contract or arrangement.

         (ix)  The Company and each of its Subsidiaries has been and continues
               to be an includible corporation which is a member of the
               affiliated group (within the meaning of Section 1504 of the Code)
               for which the Company files a consolidated return as the common
               parent.

         (x)   There are no outstanding requests, agreements, consents or
               waivers to extend the statutory period of limitations applicable
               to the assessment of any Taxes or deficiencies against the
               Company or any of its Subsidiaries.

         (xi)  No power of attorney granted by the Company or any of its
               Subsidiaries with respect to any Taxes is currently in force.

               to any assets or property held, acquired or to be acquired by any
               of them, filed a consent to the application of Section 341(f) of
               the Code, or agreed to have Section 341(f)(2) of the Code apply
               to any disposition of a subsection (f) asset (as such term is
               defined in Section 341(f)(4) of the Code) owned by the Company or
               any of its Subsidiaries.

         (xiii) The Company has identified for Parent all agreements, contracts
               and arrangements with the Company and each of its Subsidiaries,
               and has provided to Parent all such information as of the date
               hereof concerning the Company and each of its Subsidiaries and
               their employees as may be necessary to enable Parent to determine
               the amount, if any, of any "excess parachute payment" within the
               meaning of Section 28OG of the Code that could result solely from
               the transactions contemplated by this Agreement.

         (xiv) Neither the Company nor any of its Subsidiaries is or has been
               during the applicable period specified in Section

         (xv)  Neither the Company nor any of its Subsidiaries has participated
               in, or cooperated with, an "international boycott" within the
               meaning of Section 999 of the Code.

         (xvi) The charges, accruals and reserves for Taxes reflected on the
               books of the Company and each of its Subsidiaries are adequate
               under GAAP to cover the Tax liabilities accruing or payable by
               the Company and each of its Subsidiaries in respect of periods
               prior to the date hereof.

         (xvii) Neither the Company nor any of its Subsidiaries is subject to
               any joint venture, partnership or other arrangement or contract
               that is treated as a partnership for U.S. federal income tax
               purposes.

         (xviii) Neither the Company nor any of its Subsidiaries is subject to
               liability for Taxes of any other person (other than with respect
               to the Company), including, without limitation, liability arising
               from the application of U.S. Treasury Regulation ss.1.1502-6 or
               any analogous provision of Tax law.

         (xix) The shares of Company Common Stock are of "a class of stock that
               is regularly traded on an established securities market" within
               the meaning of Section 1445(b)(6) of the Code.

     (c) For purposes of this Agreement, "Taxes" (including, with correlative
meaning, the term "Tax") shall include all taxes, charges, fees, levies or other
assessments, including, without limitation, all net income, gross income, gross
receipts, sales, use, service, service use, ad valorem, transfer, franchise,
profits, license, withholding, social security, payroll, employment, excise,
estimated, severance, stamp, recording, occupation, property or other taxes,
customs duties, fees, assessments or charges of any kind whatsoever, whether

     SECTION 4.11. INTELLECTUAL PROPERTY. Except as would not have a Company
Material Adverse Effect, the Company and each of its Subsidiaries owns, or
possesses valid license rights to use, all Intellectual Property (as hereinafter
defined) used in the conduct of the business. Except as would not have a Company
Material Adverse Effect, neither the execution, delivery and performance of this
Agreement by the Company, nor the consummation by the Company of the
transactions contemplated hereby, will adversely affect the right of the Company
or any of its Subsidiaries, without obtaining the consent of any person, paying
any money or taking any other action, to continue to use all Intellectual
Property of the Company or any of its Subsidiaries as such Intellectual Property
is currently used in the conduct of the business of the Company or such
Subsidiary. Neither the Company nor any of its Subsidiaries has received any
notice, nor, except as would not have a Company Material Adverse Effect, has any
basis to believe, that any Intellectual Property owned or licensed by the
Company or any of its Subsidiaries conflicts with, violates or infringes any
asserted rights of any other person. To the Company's knowledge, there is no
infringement of any proprietary right owned by or licensed by or to the Company
or any of its Subsidiaries which could, individually or in the



                                      A-12
<PAGE>

aggregate, reasonably be expected to have a Company Material Adverse Effect. As
used in this Agreement, the phrase "Intellectual Property" means all
intellectual property or other proprietary rights of every kind, including,
without limitation, all domestic or foreign patents, patent applications,
inventions (whether or not patentable), processes, products, technologies,
discoveries, works protected by copyright, computer software, apparatus, trade
secrets, trademarks (registered and unregistered) and trademark applications and
registrations, brand names, certification marks, service marks and service mark
applications and registrations, trade names, trade dress, copyright
registrations, design rights, customer lists, marketing and customer
information, mask work rights, know-how, licenses, technical information
(whether confidential or otherwise), and all documentation relating to the
foregoing.

     SECTION 4.12. STOCKHOLDER RIGHTS PLAN. The Company has not proposed,
adopted, approved or implemented any stockholder rights plan, or authorized the
issuance of any similar dividend or the distribution of any securities to its
stockholders, or entered into any agreement with respect to the foregoing (any
such plan, authorization, dividend, distribution or agreement being referred to
herein as a "Stockholder Rights Plan"), which could have the effect of
restricting, prohibiting, impeding or otherwise affecting the consummation of
the transactions contemplated by this Agreement or the Voting Agreement, in each
case by the respective parties thereto.

     SECTION 4.13. INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION
STATEMENT. None of the information to be supplied by the Company for inclusion
in (i) the Registration Statement to be filed with the SEC by Parent on Form S-4
under the Securities Act for the purpose of registering the shares of Parent
Common Stock to be issued in connection with the Merger (the "Registration
Statement") or (ii) the joint proxy statement-prospectus to be distributed in
connection with the Company's meetings of stockholders to vote upon this
Agreement (the "Proxy Statement-Prospectus") will, in the case of the
Registration Statement, at the time it becomes effective and at the Effective
Time, or, in the case of the Proxy Statement-Prospectus or any amendments
thereof or supplements thereto, at the time of the mailing of the Proxy
Statement-Prospectus and any amendments or supplements thereto, and at the time
of the meeting of stockholders of the Company to be held in connection with the
Merger, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Proxy Statement-Prospectus will comply as to form in all
material respects with the applicable provisions of the Exchange Act, and the
rules and regulations promulgated thereunder, except that no representation is
made by the Company with respect to statements made therein based on information
supplied by Parent or its representatives for inclusion in the Proxy
Statement-Prospectus or with respect to information concerning Parent or any of
its Subsidiaries incorporated by reference in the Proxy Statement-Prospectus.

     SECTION 4.14. EMPLOYEES. Except as set forth on SCHEDULE 4.14 or SCHEDULE
4.15, there are no employment or severance or termination agreements, policies,
plans, commitments or other Contracts, whether written or oral, accruing to the
benefit of any employee, director or independent contractor of the Company or
any of its Subsidiaries. To the knowledge of the Company, no executive, key
employee or group of employees has any plans to terminate his, her or their
employment with the Company or any of its Subsidiaries, whether as a result of
the Merger or otherwise, except as contemplated by this Agreement. Except as


                                      A-13
<PAGE>

disclosed on Schedule 4.14, the Company has complied in all material respects
with governmental requirements and laws relating in any way whatsoever to the
employment of labor, except where the failure to do so would not have a Company
Material Adverse Effect. Except as disclosed on Schedule 4.14 or 4.7, there are
no actions, charges or complaints currently pending, or to the knowledge of the
Company, threatened (and to the knowledge of the Company, there is no basis
therefor), against the Company or any of its Subsidiaries, relating to alleged
employment discrimination, failure to pay appropriate wages or overtime pay or
other compensation, unfair labor practices, equal pay discrimination,
affirmative action noncompliance, occupational safety and health, breach of
employment contract, employee benefit matters, wrongful discharge or other
employment-related matters which can reasonably be expected if adversely
determined to have a Company Material Adverse Effect. Except as disclosed on
Schedule 4.14, all levies, assessments and penalties made against the Company
pursuant to any applicable workers' compensation legislation in any jurisdiction
in which the Company conducts business have been paid by the Company where the
failure to so pay could have a Company Material Adverse Effect. Except for
contracts shown on Schedule 4.14, neither the Company nor any of its
Subsidiaries is a party to any Contracts with any labor union or employee
association nor has the Company or any of its Subsidiaries made commitments to
or conducted negotiations with any labor union or employee association with
respect to any future contracts. The Company is not aware of any current
attempts to organize or establish any labor union or employee association with
respect to any employees of the Company or any of its Subsidiaries, and there is
no existing or pending certification of any such union with regard to a
bargaining unit.

three (3) calendar years preceding the date of this Agreement (the "Company
Plans"), by the Company and each of its Subsidiaries or by any trade or
business, whether or not incorporated (an "ERISA Affiliate"), which together
with the Company or any of its Subsidiaries would be deemed a "single employer"
within the meaning of Section 4001 of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"). Neither the Company, any of its Subsidiaries
nor any ERISA Affiliate has any formal plan or commitment to create any
additional plan or modify any existing Company Plan.

     (b) Except as set forth on Schedule 4.15(b), each of the Company Plans that
is subject to ERISA is in compliance with ERISA in all material respects; each
of the Company Plans intended to be "qualified" within the meaning of Section
401(a) of the Code is so qualified, no event has occurred which may affect such
qualification and the trusts maintained thereunder are exempt from taxation
under Section 501(a) of the Code; no Company Plan has an accumulated or waived
funding deficiency within the meaning of Section 412 of the Code; neither the
Company nor an ERISA Affiliate has incurred, directly or indirectly, any
material liability

                                      A-14
<PAGE>

(including any material contingent liability) to or on account of a Company Plan
pursuant to Title IV of ERISA; no proceedings have been instituted to terminate
any Company Plan that is subject to Title IV of ERISA; no "reportable event," as
such term is defined in Section 4043(b) of ERISA, has occurred with respect to
any Company Plan; and no condition exists that presents a material risk to the
Company or an ERISA Affiliate of incurring a liability to or on account of a
Company Plan pursuant to Title IV of ERISA. Except as set forth on Schedule
4.15(b), neither the Company nor any ERISA Affiliate has any unfunded liability
for (i) post-retirement welfare benefits including retiree life and medical
benefits; or (ii) pension benefits under a Company Plan subject to Title IV of
ERISA.

     (c) Except as set forth on Schedule 4.15(c), the current value of the
assets of each of the Company Plans that are subject to Title IV of ERISA, based
upon the actuarial assumptions (to the extent reasonable) presently used by the
Company Plans, exceeds the present value of the accrued benefits under each such
Company Plan; no Company Plan is a multiemployer plan (within the meaning of
Section 4001(a)(3) of ERISA) and no Company Plan is a multiple employer plan as
defined in Section 413 of the Code; and all contributions or other amounts
payable by the Company as of the Effective Time with respect to each Company
Plan in respect of current or prior plan years have been either paid or accrued
on the balance sheet of the Company. There are no pending, threatened or
anticipated investigations, suits/proceedings or claims (other than routine
claims for benefits) by, on behalf of or against any of the Company Plans or any
trusts related thereto or to the knowledge of the Company are there any facts
that could rise to any liability in the event of such investigation, suit,
proceeding or claim.

     (d) Except as set forth on Schedule 4.15(d), neither the Company nor any
ERISA Affiliate, nor any Company Plan, nor any trust created thereunder, nor any
trustee or administrator thereof has engaged in a transaction in connection with
which the Company or any ERISA Affiliate, any Company Plan, any such trust, or
any trustee or administrator thereof, or any party dealing with any Company Plan
or any such trust could be subject to either a material civil penalty assessed
pursuant to Section 409 or 502(i) of ERISA or a material tax imposed pursuant to
Section 4975, 4976 or 4980B of the Code. Except as set forth on Schedule
4.15(d), no amounts payable under the Company Plans will, individually or in the
aggregate, fail to be deductible for federal income tax purposes by virtue of
Section 28OG of the Code. Except as set forth on Schedule 4.15(d), no Company
Plan provides death or medical benefits (whether or not insured), with respect
to current or former employees of the Company or any ERISA Affiliate beyond
their retirement or other termination of service other than (i) coverage
mandated by applicable law or (ii) death benefits under any "employee pension
plan," as that term is defined in Section 3(2) of ERISA. The consummation of the
transactions contemplated by this Agreement will not (i) entitle any current or
former employee, director or officer of the Company or any ERISA Affiliate to
severance pay, unemployment compensation or any other payment, except as
expressly provided or disclosed in the Schedules to this Agreement or (ii)
accelerate the time of payment or vesting, or increase the amount of
compensation due any such employee or officer.

in the aggregate, reasonably be expected to have a Company Material Adverse
Effect or as disclosed on Schedule 4.16:


                                      A-15
<PAGE>

     (a) There are not any past or present conditions or circumstances that
could reasonably be expected to interfere with or prevent the conduct of the

properties of the Company or any of its Subsidiaries, including but not limited
to on-site or off-site storage, treatment, disposal or the release or threatened
release of any chemical substance, product or waste, which could, individually
or in the aggregate, reasonably be expected to give rise to: (i) liabilities or
obligations for any cleanup, remediation, disposal or corrective action or any
long-term monitoring requirements under any Environmental Law or (ii) claims
arising for personal injury, property damage, or damage to natural resources.

     (c) Neither the Company nor any of its Subsidiaries has (i) received any

matters or under any applicable Environmental Law, the Company or any of its

the management of or participated in any decisions with respect to or exercised
any influence or control over the use, generation, storage, treatment or
disposal of any hazardous or toxic materials, wastes or substances at or related

     SECTION 4.17. VOTE REQUIRED. The affirmative vote of the holders of a
majority of the outstanding shares of Company Common Stock is the only vote of
the holders of any class or series of the Company's capital stock necessary to
approve the Merger. The Board of Directors of the Company (at a meeting duly
called and held) has unanimously (i) approved this Agreement, (ii) determined
that the transactions contemplated hereby are in the best interests of the
holders of Company Common Stock and (iii) determined to recommend this
Agreement, the Merger and the other transactions contemplated hereby to such

opinion of Bear Stearns & Co. Inc. ("Bear Stearns"), dated October 5, 1999,
substantially to the effect that the Exchange Ratio provided for in the Merger
Agreement is fair from a financial point of view to the holders of the Company
Common Stock. A copy of this opinion will be delivered to Parent on or promptly

                                      A-16
<PAGE>

     SECTION 4.19. INSURANCE. The Company and each of its Subsidiaries is, and
has been continuously since January 1, 1995, insured in such amounts and against
such risks and losses as are customary for companies conducting the respective
businesses conducted by the Company and its Subsidiaries during such time
period. Neither the Company nor any of its Subsidiaries, has received any
written notice of cancellation or termination with respect to any material
insurance policy. To the knowledge of the Company, all material insurance
policies of the Company and its Subsidiaries are valid and enforceable policies
in all material respects.

     SECTION 4.20. AFFILIATE TRANSACTIONS. Except as disclosed in the Company
SEC Reports or as otherwise disclosed in the Schedules to this Agreement, there
are no material Contracts or other transactions between the Company, on the one
hand, and any (i) officer or director of the Company, (ii) record or beneficial
owner of five percent or more of the voting securities of the Company or (iii)
affiliate (as such term is defined in Regulation 12b-2 promulgated under the
Exchange Act) of any such officer, director or beneficial owner, on the other
hand.

     SECTION 4.21. BROKERS. Except for Bear Stearns, no broker, finder or
financial advisor is entitled to any brokerage, finder's or other fee or
commission in connection with the Merger or the transactions contemplated by
this Agreement based upon arrangements made by or on behalf of the Company.

     SECTION 4.22. YEAR 2000. The Company and each of its Subsidiaries has
implemented a program (the "Year 2000 Program") to: (i) inventory, assess,
remediate, replace or upgrade, and test for "Year 2000 Functionality" (as
hereinafter defined) all computer hardware, software, systems, networks,
interfaces (including interfaces with third parties), devices and building
infrastructure elements that may contain software, firmware or embedded devices
that could be date sensitive (collectively, "Date-sensitive Devices") that are
used by the Company or any of its Subsidiaries and are material to the conduct
of the business of the Company or such Subsidiary (collectively, "Remediation
Efforts"), (ii) evaluate the efforts of all third parties providing goods or
services material to the conduct of the business of the Company or any of its
Subsidiaries (including, without limitation, third party service providers and
providers of public infrastructure services) to assure Year 2000 Functionality
within their organizations and to assure the continued availability of the goods
or services they provide that are material to the business of the Company or any
of its Subsidiaries prior to, during and after the year-end change from 1999 to
2000 (collectively "Supply Chain Evaluation"), and (iii) develop contingency
plans to avert and, if necessary, promptly recover from, any failure of the
Company, any of its Subsidiaries or any third party material to their respective
businesses to be able to continue to conduct business as usual prior to, during
and after the year-end change from 1999 to 2000 as a result of loss of Year 2000
Functionality by such entity or other entities in their respective supply chains
(collectively, "Contingency Plans"). The Company and each of its Subsidiaries
has completed its Remediation Efforts and Supply Chain Evaluation, and as of the
date hereof the Company is not aware of any condition or circumstance that will
impede the ability of the Company or any Subsidiary to conduct business as usual
prior to, during and after the year-end change from 1999 to 2000. The Company
and each of its Subsidiaries has substantially completed its Contingency Plans.
As used in this Agreement, the phrase "Year 2000 Functionality" means that,
except as would not cause a Company Material Adverse Effect, all date-sensitive
devices material to the conduct of the entity's business will provide

                                      A-17
<PAGE>

uninterrupted functionality to record, store, process and present calendar dates
on or after January 1, 2000 (including without limitation properly treating 2000
as a leap year) in substantially the same manner and with the same functionality
as such date-sensitive devices have heretofore recorded, stored, processed and
presented calendar dates falling on or before December 31, 1999. The Company
reasonably believes as of the date hereof that the remaining costs of fully
implementing its Year 2000 Program will not exceed the amounts reflected in its
Report on Form 10-Q for the quarter ended June 30, 1999.

                                   ARTICLE V.

     (a) Parent is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has the corporate power and
authority to carry on its business as it is now being, conducted or presently
proposed to be conducted. Parent is duly qualified as a foreign corporation to
do business, and is in good standing, in each jurisdiction where the character
of its properties owned or held under lease or the nature of its activities make
such qualification necessary, except where the failure to be so qualified will
not have a Parent Material Adverse Effect (as hereinafter defined). Sub is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. Sub has not engaged in any business (other than in
connection with this Agreement and the transactions contemplated hereby) since
the date of its incorporation.

required to be set forth as an exhibit to Parent's Annual Report on Form 10-K
pursuant to the rules and regulations under the Exchange Act (the "Parent

validly existing and in good standing under the laws of its jurisdiction of
organization or incorporation and has the corporate power and authority to own
or lease its properties and to carry on its business as it is presently being
conducted, except for failures, if any, to be so organized, validly existing or
in good standing or to have such corporate power and authority which would not
in the aggregate have a Parent Material Adverse Effect.

     (c) The copies of the Certificate of Incorporation and By-Laws of Parent
and Sub heretofore delivered to the Company are complete and correct copies of
such instruments as presently in effect.

     (d) As used in this Agreement, any reference to any event, change or effect
having a "Parent Material Adverse Effect" shall mean that such event, change or
effect is, individually or in the aggregate, materially adverse to the business,
operations, properties, assets (including intangible assets), liabilities
(including contingent liabilities), condition (financial or other) or results of
operations of the Parent and its Subsidiaries taken as a whole or to the ability
of Parent to consummate the Merger and the other transactions contemplated by
this Agreement, other than any change, effect or circumstance relating to or
resulting from: (i) general changes in the

                                      A-18
<PAGE>

industries in which Parent operates its business; and (ii) changes in general
economic conditions or securities markets in general.

(as hereinafter defined), (i) there is no outstanding right, subscription,

security of any kind convertible into or exchangeable for such capital stock,
and (iii) there is no voting trust or other agreement or understanding to which
Parent or Sub is a party or is bound with respect to the voting of the capital

     (d) Except for qualifying shares required by certain foreign jurisdictions,
all of the issued and outstanding capital stock of each of the Parent
Subsidiaries has been validly issued, is fully paid and nonassessable and,
except as disclosed on Schedule 5.2(d), is owned of record and beneficially,
directly or indirectly, by Parent or another Subsidiary of Parent, free of any
Liens, preemptive rights or other restrictions with respect thereto.

     SECTION 5.3. AUTHORITY RELATIVE TO THIS AGREEMENT. Each of Parent and Sub
has the requisite corporate power and authority to execute and deliver this
Agreement and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement by each of Parent and Sub and the consummation by
Parent and Sub of the transactions contemplated on their part hereby have been
duly authorized by their respective Boards of Directors, and by Parent as the
sole stockholder of Sub, and, no other corporate proceedings on the part of
Parent or Sub are necessary to authorize this Agreement or for Parent and Sub to
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by each of Parent and Sub and constitutes a
valid and binding agreement of each of Parent and Sub, enforceable against
Parent and Sub in accordance with its terms except to the extent that
enforceability may be limited by applicable bankruptcy, insolvency,

     SECTION 5.4. CONSENTS AND APPROVALS; NO VIOLATIONS. Except as set forth on
Schedule 5.4, neither the execution, delivery and performance of this Agreement
by Parent or Sub, nor the consummation by Parent or Sub of the transactions
contemplated hereby will (i) conflict with or result in any breach of any
provisions of (x) the Certificate of Incorporation or By-Laws of Parent or of
Sub or (y) the organizational documents of the Parent Subsidiaries, (ii) require
a filing with, or a permit, authorization, consent or approval of, any
Governmental Entity except in connection with or in order to comply with the
applicable provisions of the HSR Act, the filing of the Proxy
Statement-Prospectus under the Exchange Act, filings or approvals required under
state or foreign laws relating to takeovers, if applicable, state securities or
"blue sky" laws, the By-Laws of the NASD, and the filing and recordation of a
Certificate of Merger as required by the DGCL, (iii) result in a violation or
breach of, or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, cancellation or acceleration)
under, or result in the creation of a Lien on any property or asset of Parent or
any of its Subsidiaries pursuant to, any of the terms, conditions or provisions
of any material Contract to which Parent or Sub or any other Subsidiary of
Parent is a party or by which any of them or any of their properties or assets
may be bound or (iv) violate any law, order, writ, injunction, decree, statute,
rule or regulation of any Governmental Entity applicable to Parent, Sub or any
other Subsidiary of Parent or any of their properties or assets, except, in the
case of clauses (ii), (iii) and (iv), where the failure to make such filing or
obtain such authorization, consent or approval would not have, or where such
violations, breaches or defaults or Liens would not have, in any such case, a
Parent Material Adverse Effect.

     SECTION 5.5. REPORTS AND FINANCIAL STATEMENTS. Parent has timely filed all
reports required to be filed by Parent with the SEC pursuant to the Exchange Act
or the Securities Act since December 31, 1997 (collectively, the "Parent SEC
Reports"), and has previously made available to the Company true and complete
copies of all such Parent SEC Reports. Such Parent SEC Reports, as of their
respective dates, complied in all material respects with the applicable
requirements of the Securities Act and the Exchange Act, as the case may be, and
none of such SEC Reports contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. The financial statements of Parent included in the Parent
SEC Reports have been prepared in accordance with GAAP consistently applied
throughout the periods indicated (except as otherwise noted therein or, in the
case of unaudited statements, as permitted by Form 10-Q of the SEC) and fairly
present (subject, in the case of unaudited statements, to normal, recurring
year-end adjustments and any other adjustments described therein) the
consolidated financial position of Parent and its consolidated Subsidiaries as
at the dates thereof and the consolidated results of operations and cash flows
of Parent and its consolidated Subsidiaries for the periods then ended. Since
December 31, 1998, there has been no change in any of the significant accounting
(including tax accounting) policies, practices or procedures of the Parent or
any of its consolidated Subsidiaries.

     SECTION 5.6. ABSENCE OF CERTAIN CHANGES OR EVENTS; MATERIAL AGREEMENTS.
Except as set forth on Schedule 5.6 or in the Parent SEC Reports filed as of the
date of this Agreement, since December 31, 1998, (i) neither Parent nor any of
its Subsidiaries has conducted its business and operations other than in the
ordinary course of business and consistent with past practices or taken any
action that, if it had been in effect, would have violated or been inconsistent
with the provisions of Section 6.2; and (ii) there has not been any fact, event,
circumstance or change

                                      A-20

<PAGE>

affecting or relating to Parent or any of its Subsidiaries which has had or is
reasonably likely to have a Parent Material Adverse Effect. Except as described
in Section 5.4, the transactions contemplated by this Agreement will not require
a consent from or the giving of notice to a third party pursuant to the terms,
conditions or provisions of any contract to which the Parent or any of its
Subsidiaries is a party.

     SECTION 5.7. LITIGATION. Except as disclosed on Schedule 5.7 and except for
litigation disclosed in the notes to the financial statements included in the
Parent's Annual Report to Stockholders for the fiscal year ended December 31,
1998 or in the Parent SEC Reports filed subsequent thereto, as of the date
hereof, there is no suit, action, proceeding or investigation pending or, to the
best knowledge of the Parent, threatened against, the Parent or any of its
Subsidiaries or with respect to which the Parent or any of its Subsidiaries
could be required to provide indemnification or to otherwise contribute to
liabilities or damages relating thereto, the outcome of which could reasonably
be expected to have a Parent Material Adverse Effect; nor is there any judgment,
decree, injunction, rule or order of any Governmental Entity outstanding against
the Parent or any of its Subsidiaries having, or which, insofar as can
reasonably be foreseen, in the future may have a Parent Material Adverse Effect.
For purposes of this Agreement, wherever the term "Parent knowledge" or "best
knowledge of the Parent" or any phrase of similar import is used it shall mean
the actual knowledge of the directors and the executive officers of Parent, or
knowledge which such persons could reasonably be expected to possess in view of
their respective positions with the Company, and, except as provided above,
shall not include imputed, constructive or implied knowledge of any such persons

     SECTION 5.8. ABSENCE OF UNDISCLOSED LIABILITIES. Except for liabilities or
obligations which are accrued or reserved against in Parent's financial
statements (or reflected in the notes thereto) included in the Parent SEC
Reports filed as of the date of this Agreement or which were incurred after June
30, 1999 in the ordinary course of business and consistent with past practices,
none of Parent or any of its Subsidiaries has any liabilities or obligations
(whether absolute, accrued, contingent or otherwise) of a nature required by
GAAP to be reflected in a consolidated balance sheet (or reflected in the notes
thereto) and which could reasonably be expected to have a Parent Material
Adverse Effect.

     SECTION 5.9. NO DEFAULT. Neither Parent nor any of its Subsidiaries is in
breach or violation, or in default under (and no event has occurred which with
notice or the lapse of time or both would constitute such a breach, default or
violation of) any term, condition or provision of (i) the Parent's or the
respective Subsidiary's Certificate of Incorporation or By-Laws, or (ii) (x) any
order, writ, decree, statute, rule or regulation of any Governmental Entity
applicable to Parent or any of its Subsidiaries or any of their properties or
assets or (y) any Contract to which the Parent or any of its Subsidiaries is a
party or by which Parent or any of its Subsidiaries or any of their properties
or assets may be bound except in the case of this clause (ii), which breaches,
violations or defaults, individually or in the aggregate, would not have a
Parent Material Adverse Effect. The Parent and each of its Subsidiaries have,
and are in compliance with, all licenses, permits, variances, exemptions,
orders, approvals and other authorizations of all Governmental Entities as are
necessary in order to enable them to own their businesses and conduct their
businesses as currently conducted and as currently proposed to be conducted and
to enter into the transactions contemplated hereby, the lack of which, under
applicable law, rule or

                                      A-21

<PAGE>

regulation, (x) would render legally impermissible the transactions contemplated
hereby or (y) could reasonably be expected to have a Parent Material Adverse
Effect.

     SECTION 5.10. INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION
STATEMENT. None of the information to be supplied by Parent or Sub for inclusion
in (i) the Registration Statement or (ii) the Proxy Statement-Prospectus will in
the case of the Registration Statement, at the time it becomes effective and at
the Effective Time, or, in the case of the Proxy Statement-Prospectus or any
amendments thereof or supplements thereto, at the time of the mailing of the
Proxy Statement-Prospectus and any amendments or supplements thereto, and at the
time of the meeting of stockholders of the Company to be held in connection with
the Merger, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
misleading. The Registration Statement and the Proxy Statement-Prospectus will
comply as to form in all material respects with the applicable provisions of the
Securities Act and the Exchange Act, and the rules and regulations promulgated
thereunder, except that no representation is made by Parent with respect to
statements made therein based on information supplied by the Company or its
representatives for inclusion in the Registration Statement or the Proxy
Statement-Prospectus or with respect to information concerning the Company
incorporated by reference in the Registration Statement or the Proxy
Statement-Prospectus.

     SECTION 5.11. ENVIRONMENTAL PROTECTION. Except as could not, individually
or in the aggregate, reasonably be expected to have a Parent Material Adverse
Effect:

     (a) There are not any past or present conditions or circumstances that
could reasonably be expected to interfere with or prevent the conduct of the
business of Parent or any of its Subsidiaries in compliance with: (i) any order
of any court or arbitration board or tribunal, or any law, ordinance,
governmental rule or regulation related to human health or the environment
("Environmental Law"); or (ii) the terms or conditions of any permits,
approvals, licenses or consents required to be issued by any Governmental Entity
pursuant to any applicable Environmental Law.

     (b) There are not any past or present conditions or circumstances at,
arising out of, or related to, any current or former business, assets or
properties of Parent or any of its Subsidiaries, including but not limited to
on-site or off-site storage, treatment, disposal or the release or threatened
release of any chemical substance, product or waste, which could, individually
or in the aggregate, reasonably be expected to give rise to: (i) liabilities or
obligations for any cleanup, remediation, disposal or corrective action or any
long-term monitoring requirements under any Environmental Law or (ii) claims
arising for personal injury, property damage, or damage to natural resources.

     (c) Neither Parent nor any of its Subsidiaries has (i) received any notice
of noncompliance with, violation of, or liability or potential liability under
any Environmental Law or (ii) entered into any consent decree, settlement or
order or is subject to any order of any court or Governmental Entity or tribunal
under any Environmental Law or relating to the cleanup of any hazardous or toxic
materials, wastes, substances or any pollutants or contamination.

                                      A-22

<PAGE>

     (d) There are no persons or entities whose liability, for any environmental
matters or under any applicable Environmental Law, Parent or any of its
Subsidiaries has retained or assumed contractually.

     (e) Neither Parent nor any of its Subsidiaries has handled or directed the
management of or participated in any decisions with respect to or exercised any
influence or control over the use, generation, storage, treatment or disposal of
any hazardous or toxic materials, wastes or substances at or related to any of
their business, assets or properties.

     SECTION 5.12. VOTE REQUIRED. The affirmative vote of Parent, as the sole
stockholder of all outstanding shares of Sub Common Stock, is the only vote of
the holders of any class or series of Sub capital stock necessary to approve the
Merger. The Board of Directors of Parent (at a meeting duly called and held) has
unanimously (i) approved this Agreement, (ii) determined that the transactions
contemplated hereby are fair to and in the best interests of Parent and the
holders of Parent Common Stock, and (iii) determined to cause Parent, as the
sole stockholder of Sub, to approve and adopt this Agreement. The Board of
Directors of Sub (by unanimous written consent) has approved this Agreement.

     SECTION 5.13. INSURANCE. Parent and each of its Subsidiaries is, and has
been continuously since January 1, 1995, insured in such amounts and against
such risks and losses as are customary for companies conducting the respective
businesses conducted by Parent and its Subsidiaries during such time period.
Neither Parent nor any of its Subsidiaries has received any written notice of
cancellation or termination with respect to any material insurance policy. To
the knowledge of the Parent, all material insurance policies of Parent and its
Subsidiaries are valid and enforceable policies in all material respects.

     SECTION 5.14. YEAR 2000. Parent and each of its Subsidiaries has
implemented a program (the "Year 2000 Program") to: (i) inventory, assess,
remediate, replace or upgrade, and test for "Year 2000 Functionality" (as
hereinafter defined) all computer hardware, software, systems, networks,
interfaces (including interfaces with third parties), devices and building
infrastructure elements that may contain software, firmware or embedded devices
that could be date sensitive (collectively, "Date-sensitive Devices") that are
used by Parent or any of its Subsidiaries and are material to the conduct of the
business of Parent or such Subsidiary (collectively, "Remediation Efforts"),
(ii) evaluate the efforts of all third parties providing goods or services
material to the conduct of the business of Parent or any of its Subsidiaries
(including, without limitation, third party service providers and providers of
public infrastructure services) to assure Year 2000 Functionality within their
organizations and to assure the continued availability of the goods or services
they provide that are material to the business of Parent or any of its
Subsidiaries prior to, during and after the year-end change from 1999 to 2000
(collectively "Supply Chain Evaluation"), and (iii) develop contingency plans to
avert and, if necessary, promptly recover from, any failure of Parent, any of
its Subsidiaries or any third party material to their respective businesses to
be able to continue to conduct business as

                                      A-23

<PAGE>

usual prior to, during and after the year-end change from 1999 to 2000 as a
result of loss of Year 2000 Functionality by such entity or other entities in
their respective supply chains (collectively, "Contingency Plans"). Parent and
each of its Subsidiaries has completed its Remediation Efforts and Supply Chain
Evaluation, and as of the date hereof Parent is not aware of any condition or
circumstance that will impede the ability of Parent or any Subsidiary to conduct
business as usual prior to, during and after the year-end change from 1999 to
2000. Parent and each of its Subsidiaries has substantially completed its
Contingency Plans. As used in this Agreement, the phrase "Year 2000
Functionality" means that, except as would not cause a Parent Material Adverse
Effect, all date-sensitive devices material to the conduct of the entity's
business will provide uninterrupted functionality to record, store, process and
present calendar dates on or after January 1, 2000 (including without limitation
properly treating 2000 as a leap year) in substantially the same manner and with
the same functionality as such date-sensitive devices have heretofore recorded,
stored, processed and presented calendar dates falling on or before December 31,
1999. Parent reasonably believes as of the date hereof that the remaining costs
of fully implementing its Year 2000 Program will not exceed the amounts
reflected in its Report on Form 10-Q for the quarter ended June 30, 1999.

     SECTION 5.15. AFFILIATE TRANSACTIONS. Except as disclosed in the Parent SEC
Reports, there are no material Contracts or other transactions between the
Parent, on the one hand, and any (i) officer or director of the Parent, (ii)
record or beneficial owner of five percent or more of the voting securities of
the Parent or (iii) affiliate (as such term is defined in Regulation 12b-2
promulgated under the Exchange Act) of any such officer, director or beneficial
owner, on the other hand.

of this Agreement by the stockholders of the Company, nothing contained in this

furnishing information to, or entering into and engaging in discussions or
negotiations with, any person that makes a bona fide unsolicited written
proposal that the Board of Directors of the Company determines in good faith,
after consultation with the Company's financial advisors and independent legal
counsel, can be reasonably expected to result in a Superior Proposal; provided,
that prior to furnishing such information to, or entering into discussions or

confidentiality agreement containing customary terms (which need not contain
"standstill" or similar provisions); (ii) complying with Rule 14e-2 promulgated
under the Exchange Act with regard to a tender or exchange offer or making any
disclosure required under applicable law; or (iii) failing to make or
withdrawing or modifying its recommendation referred to in Sections 4.17 and 7.4
following the making of a Superior Proposal if, solely in the case of this

based upon the advice of independent legal counsel, determines in good faith
that such action is necessary for the Board of Directors of the Company to
comply with its fiduciary duties under applicable law.

     (b) For purposes of this Agreement, "Alternative Acquisition" shall mean
any of the following involving the Company: (i) any merger, consolidation, share
exchange, business combination, issuance or purchase of securities or other
similar transaction; (ii) any sale, lease, exchange, mortgage, pledge, transfer
or other disposition of the assets of the Company in a single transaction or
series of related transactions; (iii) any tender offer or exchange offer for the
Company securities or the filing of a registration statement under the
Securities Act in connection with any such exchange offer; in the case of
clauses (i), (ii) or (iii) above, which transaction would result in a third
party (or its stockholders) acquiring more than 35% of the

                                      A-27

<PAGE>

voting power of the shares of the Common Stock of the Company then outstanding
or more than 35% of the assets of the Company and its Subsidiaries, taken as a
whole; or (iv) any public announcement of an agreement, proposal, plan or
intention to do any of the foregoing, either during the effectiveness of this
Agreement or at any time thereafter, other than in each of (i), (ii), (iii) and
(iv) the transactions contemplated by this Agreement.

     (c) For purposes of this Agreement, a "Superior Proposal" means any
proposal made by a third party which would result in such party (or in the case
of a parent-to-parent merger, its stockholders) acquiring, directly or
indirectly, including pursuant to a tender offer, exchange offer, merger,
consolidation, share exchange, business combination, share purchase, asset
purchase, recapitalization, liquidation, dissolution, joint venture or similar
transaction, more than 50% of the voting power of the shares of the Common Stock
of the Company then outstanding or all or substantially all the assets of the
Company and its Subsidiaries, taken as a whole, for consideration which the
Board of Directors of the Company determines in its good faith judgment to be
financially more favorable to the Company stockholders than the Merger and with
respect to which the Board of Directors of the Company determines, in its good

additional conditions, unless waived in writing by Parent:

     (a) REPRESENTATIONS AND WARRANTIES. Each of the representations and

with requested representations. The specific provisions of each such certificate
and representation shall be in form and substance satisfactory to Gardner,
Carton.

     (e) FINANCING COMMITMENT. Parent shall have received on or before October

would not, individually or in the aggregate, have a Parent Material Adverse
Effect, and the Company shall have received a certificate signed on behalf of
Parent by the chief executive officer or the chief operating officer of Parent
to such effect.

     (b) PERFORMANCE OF OBLIGATIONS OF PARENT AND SUB. Each of Parent and Sub
shall have performed in all material respects all obligations required to be

                                     FORM OF
                                VOTING AGREEMENT

     VOTING AGREEMENT (the "Agreement"), dated as of October __, 1999, between
HealthPlan Services Corporation, a Delaware corporation (the "Company"),
________________ (the "Stockholder") and UICI, a Delaware corporation
("Parent").

     WHEREAS, concurrently with the execution of this Agreement, the Company,
Parent and UICI Acquisition Co., a Delaware corporation and a wholly owned
subsidiary of Parent ("Sub"), have entered into an Agreement and Plan of Merger
(as the same may be amended from time to time, the "Merger Agreement"),
providing for the merger (the "Merger") of Sub with and into the Company
pursuant to the terms and conditions of the Merger Agreement; and

     WHEREAS, upon consummation the Merger, the stockholders of the Company will
receive a number of shares of common stock, par value $.01 per share, of Parent
("Parent Common Stock") equal to the Exchange Ratio (as defined in the Merger
Agreement) for each share of common stock, par value $.01 per share (the
"Company Common Stock") of the Company owned by them;

     WHEREAS, the Stockholder owns of record and beneficially __________ shares
of Company Common Stock and wish to enter into this Agreement with respect to
__________ of such shares (such __________ shares of Company Common Stock being
referred to as the "Shares"); and

     WHEREAS, in order to induce Parent to enter into the Merger Agreement, the
Stockholder has agreed, upon the terms and subject to the conditions set forth
herein, to vote the Shares and to deliver an irrevocable proxy to Parent to vote
the Shares at a meeting of the Company's stockholders, in favor of approval and
adoption of the Merger Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

     1. AGREEMENT TO VOTE SHARES. The Stockholder agrees during the term of this
Agreement to vote the Stockholder's Shares, in person or by proxy, (a) in favor
of approval and adoption of the Merger Agreement and the Merger at every meeting
of the stockholders of the Company at which such matters are considered and at
every adjournment thereof, and (b) against an Alternative Acquisition (as such
term is defined in the Merger Agreement). The Stockholder agrees to deliver to
Parent upon request immediately prior to any vote contemplated by clause (a) or
(b) above a proxy substantially in the form attached hereto as Annex A (a
"Proxy"), which Proxy shall be irrevocable during the term of this Agreement to
the extent permitted under Delaware law, and Parent agrees to vote the Shares
subject to each such Proxy in favor of approval and adoption of the Merger
Agreement and the Merger.

                                      A-42
<PAGE>

     2. NO VOTING TRUSTS. The Stockholder agrees that the Stockholder will not,
nor will the Stockholder permit any entity under the Stockholder's control to,
deposit any of the Stockholder's Shares in a voting trust or subject any of its
Shares to any arrangement with respect to the voting of the Shares inconsistent
with this Agreement.

     3. LIMITATION ON DISPOSITIONS AND PROXIES. During the term of this
Agreement, the Stockholder agrees not to sell, assign, pledge, transfer or
otherwise dispose of, or grant any proxies with respect to (except for a Proxy
or a proxy which is not inconsistent with the terms of this Agreement) any of
the Stockholder's Shares.

     4. SPECIFIC PERFORMANCE. Each party hereto acknowledges that it will be
impossible to measure in money the damage to the other party if a party hereto
fails to comply with the obligations imposed by this Agreement, that, in the
event of any such failure, the other party will not have an adequate remedy at
law or in damages. Accordingly, each party hereto agrees that injunctive relief
or other equitable remedy, addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that the other party has an adequate remedy at law. Each
party hereto agrees that it will not seek, and agrees to waive any requirement
for, the securing or posting of a bond in connection with any other party's
seeking or obtaining such equitable relief.

     5. TERM OF AGREEMENT; TERMINATION. Subject to Section 9(e), the term of
this Agreement shall commence on the date hereof and such term and this
Agreement shall terminate upon the earliest to occur of (i) the Effective Time,
and (ii) the date on which the Merger Agreement is terminated in accordance with
its terms. Upon such termination, no party shall have any further obligations or
liabilities hereunder; provided, that such termination shall not relieve any
party from liability for any breach of this Agreement prior to such termination.

     6. REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER. The Stockholder
represents and warrants to Parent that, as of the date hereof, (a) such
Stockholder has full legal power and authority to execute and deliver this
Agreement and the Proxy, and (b) such Stockholder's Shares are free and clear of
all proxies (except for a proxy which is not inconsistent with the terms of this
Agreement).

     7. ENTIRE AGREEMENT. This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by all parties hereto. No waiver of any provisions
hereof by any party shall be deemed a waiver of any other provisions hereof by
any such party, nor shall any such waiver be deemed a continuing waiver of any
provision hereof by such party.

     8. NOTICES. All notices, requests, claims, demands or other communications
hereunder shall be in writing and shall be deemed given when delivered
personally, upon receipt of a transmission confirmation if sent by telecopy or
like transmission (with confirmation) and on the next business day when sent by

                            FORM OF AFFILIATE LETTER

                              _______________, 1999

- ------------------------
- ------------------------
- ------------------------
Attention:
          ------------------------

Gentlemen:

     I have been advised that as of the date of this letter I may be deemed to
be an "affiliate" of _________________________, a Delaware corporation (the
"Company"), as the term "affiliate" is defined for purposes of paragraphs (c)
and (d) of Rule 145 of the rules and regulations (the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act"). Pursuant to the terms of the
Agreement and Plan of Merger dated as of _______________, 1999 (the
"Agreement"), by and among _________________________, a Delaware corporation
("Parent"), _________________________, a Delaware corporation and a wholly owned
subsidiary of Parent ("Sub"), and the Company, Parent will acquire all of the
issued and outstanding shares of common stock, par value $.01 per share, of the
Company ("Company Common Stock") and Sub will merge with and into the Company
(the "Merger").

     As a result of the Merger, I may receive shares of Common Stock, par value
$.01 per share of Parent ("Parent Common Stock"). I would receive the Parent
Common Stock in exchange for shares (or options for shares) owned by me of
Company Common Stock.

     I represent, warrant and covenant to Parent that in the event I receive
Parent Common Stock as a result of the Merger:

     A. I shall not make any sale, transfer or other disposition of the Parent
Common Stock in violation of the Act or the Rules and Regulations.

     B. I have carefully read this letter and the Agreement and discussed the
requirements of such documents and other applicable limitations upon my ability
to sell, transfer or otherwise dispose of Parent Common Stock to the extent I
felt necessary, with my counsel or counsel for the Company.

     C. I have been advised that the issuance of Parent Common Stock to me
pursuant to the Merger has been registered with the Commission under the Act on
a Registration Statement Form S-4. However, I have also been advised that,
because at the time the Merger is submitted

                                      A-47
<PAGE>

for a vote of the stockholders of the Company, (a) I may be deemed to be an
affiliate of the Company and (b) the distribution by me of the Parent Common
Stock has not been registered under the Act, I may not sell, transfer or
otherwise dispose of Parent Common Stock issued to me in the Merger unless (i)
such sale, transfer or other disposition is made in conformity with the volume
and other limitations of Rule 145 promulgated by the Commission under the Act,
(ii) such sale, transfer or other disposition has been registered under the Act
or (iii) in the opinion of counsel reasonably acceptable to Parent, such sale,
transfer or other disposition is otherwise exempt from registration under the
Act.

     D. I understand that Parent is under no obligation to register the sale,
transfer or other disposition of the Parent Common Stock by me or on my behalf
under the Act or to take any other action necessary in order to make compliance
with an exemption from such registration available solely as a result of the
Merger.

     E. I also understand that there will be placed on the certificates for the
Parent Common Stock issued to me, or any substitutions therefor, a legend
stating in substance:

      "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
      TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
      1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE
      TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED
       _______________, 1999 BETWEEN THE REGISTERED HOLDER HEREOF AND
       _________________________, A COPY OF WHICH AGREEMENT IS ON FILE AT
              THE PRINCIPAL OFFICES OF _________________________."

     F. I also understand that unless a sale or transfer is made in conformity
with the provisions of Rule 145, or pursuant to a registration statement, Parent
reserves the right to put the following legend on the certificates issued to any
transferee:

       "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED

       RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED

legend after one year unless the provisions of Rule 145(d)(2) have been amended
to require a longer period than one year.

                                OPTION AGREEMENT

     OPTION AGREEMENT, dated as of October 5, 1999 by and between HealthPlan
Services Corporation, a Delaware corporation ("Grantor"), and UICI, a Delaware
corporation ("Acquiror").

     WHEREAS, concurrently with the execution and delivery of this Agreement,
Grantor and Acquiror are entering into an Agreement and Plan of Merger, dated as
of the date hereof (the "Merger Agreement"), which provides, among other things,
upon the terms and subject to the conditions thereof, for the merger of Grantor
with and into a wholly-owned subsidiary of Acquiror (the "Merger"); and

     WHEREAS, as a condition to Acquiror's willingness to enter into the Merger
Agreement, Acquiror has requested that Grantor agree, and Grantor has so agreed,
to grant to Acquiror an option with respect to certain shares of Grantor's
common stock, on the terms and subject to the conditions set forth herein.

     NOW, THEREFORE, to induce Acquiror to enter into the Merger Agreement, and
in consideration of the mutual covenants and agreements set forth herein and in
the Merger Agreement, the parties hereto agree as follows:

     1. GRANT OF OPTION. Grantor hereby grants Acquiror an irrevocable option
(the "Grantor Option") to purchase up to 1,500,000 shares, subject to adjustment
as provided in Section 6 hereof (such shares being referred to herein as the
"Grantor Shares") of common stock, $.01 par value, of Grantor (the "Grantor
Common Stock") in the manner set forth below at a price (the "Exercise Price")
per Grantor share of $7.375 payable in cash.

     2. EXERCISE OF OPTION. The Grantor option may be exercised by Acquiror, in
whole or in part, at any time or from time to time after the Merger Agreement is
terminated and a termination fee is payable under circumstances which would
entitle Acquiror to the termination fee under Section 9.2(b)(i) or 9.2(b)(ii) of
the Merger Agreement.

     In the event Acquiror wishes to exercise the Grantor Option, Acquiror shall
deliver to Grantor a written notice (an "Exercise Notice") specifying the total
number of Grantor Shares it wishes to purchase. Each closing of a purchase of
Grantor Shares (a "Closing") shall occur at a place, on a date and at a time
designated by Acquiror in an Exercise Notice delivered at least two business
days prior to the date of the Closing. The Grantor Option shall terminate upon
the earlier of: (i) the Effective Time; or (ii) two years following the first
event that triggers the obligation of Grantor to pay the termination fee under
Section 9.2(b)(i) or 9.2(b)(ii) of the Merger Agreement (or if, at the
expiration of such two year period the Grantor Option cannot be exercised by
reason of any applicable judgment, decree, order, law or regulation, 10 business
days after such impediment to exercise shall have been removed or shall have
become final and not subject to appeal). Notwithstanding the foregoing, the
Grantor Option may not be exercised if Acquiror is in material breach of any of
its representations or warranties, or in material breach of any of its covenants
or agreements, contained in this Agreement or in the Merger Agreement. Upon the
giving by Acquiror to Grantor of the Exercise Notice and the tender of the
applicable aggregate Exercise Price, Acquiror shall be deemed to be the holder
of record of the Grantor Shares issuable upon such exercise, notwithstanding
that the stock transfer books of Grantor shall then be closed or that
certificates representing such Grantor Shares shall not then be actually
delivered to Acquiror.

                                      B-1
<PAGE>

     3. CLOSING. At any Closing, (a) Grantor will deliver to Acquiror or its
designee a single certificate in definitive form representing the number of
Grantor Shares designated by Acquiror in its Exercise Notice, such certificate
to be registered in the name of Acquiror and to bear the legend set forth in
Section 7 and (b) Acquiror will deliver to Grantor the aggregate Exercise Price
for the Grantor Shares so designated and being purchased by wire transfer of
immediately available funds or certified check or bank check. Grantor shall pay
all expenses, and any and all United States federal, state and local taxes and
other charges that may be payable in connection with the preparation, issue and
delivery of its stock certificates under this Agreement.

     4. REPRESENTATIONS AND WARRANTIES AND COVENANTS OF GRANTOR. Grantor
represents and warrants to Acquiror that (a) Grantor is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the corporate power and authority to enter into this Agreement
and to carry out its obligations hereunder, (b) the execution and delivery of
this Agreement by Grantor and the consummation by Grantor of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Grantor and no other corporate proceedings on the part of Grantor
are necessary to authorize this Agreement or any of the transactions
contemplated hereby, (c) this Agreement has been duly executed and delivered by
Grantor, constitutes a valid and binding obligation of Grantor and, assuming
this Agreement constitutes a valid and binding obligation of Acquiror, is
enforceable against Grantor in accordance with its terms, (e) Grantor has taken
all necessary corporate action to authorize and reserve for issuance and to
permit it to issue, upon exercise of the Grantor Option in accordance with its
terms, and at all times from the date hereof through the expiration of the
Grantor Option will have reserved, 1,500,000 authorized and unissued Grantor
Shares, such amount being subject to adjustment as provided in Section 6, all of
which, upon their issuance and delivery in accordance with the terms of this
Agreement, will be validly issued, fully paid and nonassessable, (f) upon
delivery of the Grantor Shares to Acquiror upon the exercise of the Grantor
Option in accordance with its terms, Acquiror will acquire the Grantor Shares
free and clear of all claims, liens, charges, encumbrances and security
interests of any nature whatsoever, (g) the execution and delivery of this
Agreement by Grantor does not, and the consummation by Grantor of the
transactions contemplated hereby will not, violate, conflict with, or result in
a breach of any provision of, or constitute a default (with or without notice or
lapse of time, or both) under, or result in the termination of, or accelerate
the performance required by, or result in a right of termination, cancellation,
or acceleration of any obligation or the loss of a material benefit under, or
the creation of a lien, pledge, security interest or other encumbrance on assets
(any such conflict, violation, default, right of termination, cancellation or
acceleration, loss or creation, a "Violation") of Grantor pursuant to, (A) any
provision of the Certificate of Incorporation or bylaws of Grantor, (B) any
provisions of any material loan or credit agreement, note, mortgage, indenture,

properties or assets, (h) the execution and delivery of this Agreement by
Grantor does not, and the performance of this Agreement by Grantor will not,
require any consent, approval, authorization or permit of, or filing with or
notification to, any governmental authority, and (i) none of Grantor, any of its
affiliates or anyone acting on its or their behalf has issued, sold or offered
any security of Grantor to any person under circumstances that would cause the
issuance and sale of the Grantor Shares, as contemplated by this Agreement, to
be subject to the registration requirements of the Securities Act as in effect
on the date hereof and the issuance, sale and delivery of the Grantor Shares
hereunder would be exempt from the registration and prospectus delivery
requirements of the Securities Act, as in effect on the date hereof (and Grantor
shall not take any action which would cause the issuance, sale and delivery of
the Grantor Shares hereunder not to be exempt from such requirements). Grantor
agrees that any Grantor Shares issued to Acquiror upon the exercise of the
Grantor Option will be approved for listing on the New York Stock Exchange.

                                      B-2

view to the public distribution thereof in violation of any applicable provision
of the Securities Act.

     6. ADJUSTMENT UPON CHANGES IN CAPITALIZATION. Without limitation to any
restriction on Grantor contained in this Agreement or in the Merger Agreement,
in the event of any change in Grantor Common Stock by reason of stock dividends,
splitups, mergers, (other than the Merger), recapitalizations, combinations,
exchange of shares or the like, the type and number of shares or securities
subject to the Grantor Option, and the purchase price per share provided in
Section 1, shall be adjusted appropriately to restore to Acquiror its rights
hereunder.

     7. RESTRICTIVE LEGENDS. Each certificate representing shares of Grantor
Common Stock issued to Acquiror hereunder, at a Closing, shall include a legend
in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
     ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
     AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
     TRANSFER AS SET FORTH IN THE OPTION AGREEMENT, DATED AS OF OCTOBER 5, 1999,
     A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER UPON REQUEST.

     It is understood and agreed that: (i) the reference to the resale
restrictions of the Securities Act in the above legend shall be removed by
delivery of substitute certificate(s) without such reference if Acquiror shall
have delivered to the other party a copy of a letter from the staff of the
Securities and Exchange Commission, or an opinion of counsel, in form and
substance satisfactory to the other party, to the effect that such legend is not
required for purposes of the Securities Act; (ii) the reference to the
provisions of this Agreement in the above legend shall be removed by delivery of
substitute certificate(s) without such reference if the shares have been sold or
transferred in compliance with the provisions of this Agreement and in
circumstances that do not require the retention of such reference; and (iii) the
legend shall be removed in its entirety if the conditions in the preceding
clauses (i) and (ii) are both satisfied. In addition, such certificates shall
bear any other legend as may be required by law.

     8. REGISTRATION STATEMENT.

     (a) If at any time or times after the Option has become exercisable Grantor
determines to file with the Securities and Exchange Commission a registration
statement covering any Grantor Common Stock (other than Grantor Common Stock
issuable to officers and employees pursuant to an employee benefit plan
registered on Form S-8), Grantor shall notify Acquiror, at least 15 days prior
to the filing of such proposed registration statement. If Acquiror requests
Grantor in writing, within

                                       B-3
<PAGE>

10 days of the receipt of notification from Grantor, to include in such
registration statement any Grantor Shares then held by Acquiror, then, Grantor
shall use its best efforts to include those Grantor Shares in the registration
statement, to have the registration declared effective and to keep such
registration current for a period of not less than 180 days. If Acquiror decides
not to (or is precluded from including) all of its Grantor Shares in any
registration statement thereafter filed by Grantor, Acquiror will nevertheless
continue to have the right under this Section 8(a) to include its Grantor Shares
in a future registration of Grantor.

     (b) At any time, Acquiror may demand registration under the Securities Act
of all or part of the Grantor Shares then held by Acquiror. Acquiror shall be
limited to one demand under this Section 8(b) and such demand shall be made by
written notice to Grantor, which notice shall specify the number of Grantor
Shares requested to be registered. Upon receipt of a written demand for
registration under this Section 8(b), the Company shall use its best efforts to
register such Grantor Shares, to have the registration statement declared
effective and to keep such registration current for a period of not less than
180 days.

     (c) A registration effected under this Section 8 shall be effected at
Grantor's expense, except for underwriting discounts and commissions and the
fees and the expenses of counsel to Acquiror, and Grantor shall provide to the
underwriters such documentation (including certificates, opinions of counsel and
"comfort" letters from auditors) as are customary in connection with
underwritten public offerings as such underwriters may reasonably require. In
connection with any such registration, the parties agree (i) to indemnify each
other and the underwriters, if any, in the customary manner, (ii) if applicable,
to enter into an underwriting agreement in form and substance customary for
transactions of such type with the underwriters participating in such offering
and (iii) to take all further actions which shall be reasonably necessary to
effect such registration and sale (including, if the underwriters, if any, deem
it necessary, participating in road-show presentations).

     9. BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and permitted assigns. Except as expressly
provided for in this Agreement, neither this Agreement nor the rights or the
obligations of either party hereto are assignable, except by operation of law,
or with the written consent of the other party. Nothing contained in this
Agreement, expressed or implied, is intended to confer upon any person other
than the parties hereto and their respective permitted assigns any rights or
remedies of any nature whatsoever by reason of this Agreement.

     10. SPECIFIC PERFORMANCE. The parties recognize and agree that if for any
reason any of the provisions of this Agreement are not performed in accordance
with their specific terms or are otherwise breached, immediate and irreparable
harm or injury would be caused for which money damages would not be an adequate
remedy. Accordingly, each party agrees that, in addition to other remedies, the
other party shall be entitled to an injunction restraining any violation or
threatened violation of the provisions of this Agreement. In the event that any
action should be brought in equity to enforce the provisions of the Agreement,
neither party will allege, and each party hereby waives the defense, that there
is adequate remedy at law.

     11. ENTIRE AGREEMENT. This Agreement and the Merger Agreement (including
the exhibits and schedules thereto) constitute the entire agreement among the
parties with respect to the subject matter hereof and thereof and supersede all
other prior agreements and understandings, both written and oral, among the
parties or any of them with respect to the subject matter hereof and thereof.

                                      B-4
<PAGE>

     12. FURTHER ASSURANCES. Each party will execute and deliver all such
further documents and instruments and take all such further action as may be
necessary in order to consummate the transactions contemplated hereby.

     13. VALIDITY. The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect. In
the event any court or other competent authority holds any provisions of this
Agreement to be null, void or unenforceable, the parties hereto shall negotiate
in good faith the execution and delivery of an amendment to this Agreement in
order, as nearly as possible, to effectuate, to the extent permitted by law, the
intent of the parties hereto with respect to such provision and the economic
effects thereof. If for any reason any such court or regulatory agency
determines that Acquiror is not permitted to acquire, the full number of shares
of Grantor Common Stock provided in Section 1 hereof (as the same may be
adjusted), it is the express intention of Grantor to allow Acquiror to acquire
or to require Grantor to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof. Each party agrees
that, should any court or other competent authority hold any provision of this
Agreement or part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action required
herein, the other party shall not be entitled to specific performance of such
provision or part hereof or to any other remedy, including but not limited to
money damages, for breach hereof or of any other provision of this Agreement or
part hereof as the result of such holding or order.

     14. NOTICES. All notices and other communications hereunder shall be in
writing and shall be deemed given if (i) delivered personally, or (ii) sent by
reputable overnight courier service, or (iii) telecopied (which is confirmed),
or (iv) five days after being mailed by registered or certified mail (return
receipt requested) to the parties at the following addresses (or at such other

October 5, 1999

HealthPlan Services Corporation
3501 Frontage Road
Tampa, FL  33607

Attention:  Board of Directors

Gentlemen:

We understand that HealthPlan Services Corporation ("HPS") and UICI are
considering a transaction pursuant to which a newly-formed wholly-owned
subsidiary of UICI would be merged with and into HPS in a stock-for-stock
exchange (the "Merger"). Pursuant to the Merger, each outstanding share of
common stock of HPS would be converted into the right to receive 0.3393 shares
(the "Exchange Ratio") of UICI of common stock. The Exchange Ratio shall be
subject to adjustment as follows: (i) if the UICI Average Stock Price (as
defined below) is less than $28.00 per share and greater than or equal to $23.00
per share, the Exchange Ratio shall be fixed at 0.3393; (ii) if the UICI Average
Stock Price is greater than or equal to $28.00 per share and less than or equal
to $30.00 per share, the Exchange Ratio will be determined by dividing $9.50 by
the UICI Average Stock Price; (iii) if the UICI Average Stock Price is greater
than $30.00 and less than or equal to $33.00, the Exchange Ratio shall be fixed
at 0.3167; (iv) if the UICI Average Stock Price is greater than $33.00 per
share, the Exchange Ratio will be determined by dividing $9.50 by an amount
equal to the UICI Average Stock Price less $3.00; (v) if the UICI Average Stock
Price is less than $23.00 per share and greater than or equal to $21.00 per
share, the Exchange Ratio will be determined by dividing $9.50 by the sum of the
UICI Average Stock Price and $5.00; and (vi) if the UICI Average Stock Price is
less than $21.00 per share, the Exchange Ratio will be fixed at 0.3654. The UICI
Average Stock Price shall be defined as the average of the volume weighted
averages of the trading prices of UICI's common stock for the 20 consecutive
trading days ending on the third trading day immediately preceding the
consummation of the Merger. If HPS terminates the Merger for certain reasons,
UICI will be entitled to (i) receive a termination fee of $5 million from HPS,
and (ii) exercise an option to purchase up to 1,500,000 newly-issued shares of
HPS common stock at a price of $7.38 per share in accordance with the terms of
an Option Agreement (the "Option Agreement") to be entered into by HPS and UICI.
If UICI terminates the Merger for certain reasons, HPS shall be entitled to
receive a termination fee of $4 million from UICI.

You have provided us with copies of the proposed Agreement and Plan of Merger
(the "Agreement") and the Option Agreement both dated October 5, 1999.

You have asked us to render our opinion as to whether the Exchange Ratio to be
provided for in the Merger is fair, from a financial point of view, to the
shareholders of HPS.

In the course of our analyses for rendering this opinion, we have:

     1.  reviewed the Agreement and the Option Agreement;

     2.  reviewed HPS' Annual Reports to Shareholders and Annual Reports on Form
         10-K for the fiscal years ended December 31, 1997 and 1998, and its
         Quarterly Reports on Form 10-Q for the periods ended March 31, 1999 and
         June 30, 1999;

     3.  reviewed certain operating and financial information, including
         projections, provided to us by HPS' management relating to HPS'
         business and prospects;

     4.  met with certain members of HPS' senior management to discuss its
         operations, historical financial statements, recent financial results
         and near-term estimated financial performance, and future prospects;

     5.  reviewed UICI's Annual Reports to Shareholders and Annual Reports on
         Form 10-K for the fiscal years ended December 31, 1997 and 1998, and
         its Quarterly Reports on Form 10-Q for the periods ended March 31, 1999
         and June 30, 1999;

     6.  reviewed certain operating and financial information, including
         projections, provided to us by UICI management relating to UICI's
         business and prospects;

     7.  met with certain members of UICI's senior management to discuss its
         operations, historical financial statements, recent financial results
         and near-term estimated financial performance, and future prospects;

     8.  reviewed the historical prices and trading volumes of the common stock
         of HPS and UICI;

     9.  reviewed publicly available financial data, stock market performance
         data and valuation parameters of companies which we deemed generally
         comparable to HPS and UICI;

     10. reviewed the terms of recent acquisitions of companies which we deemed
         generally comparable to HPS;

     11. performed discounted cash flow analyses of the implied per share value
         of HPS' common stock and of UICI's common stock based on the
         projections furnished to us by HPS' management and UICI's management,
         respectively, as well as on a range of more conservative projection
         scenarios; and

     12. conducted such other studies, analyses, inquiries and investigations as
         we deemed appropriate.

                                      C-2
<PAGE>

In the course of our review, we have relied upon and assumed, without
independent verification, the accuracy and completeness of the financial and
other information, including without limitation the projections, provided to us
by HPS and UICI. With respect to HPS' and UICI's projected financial results, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the senior managements of
HPS and UICI as to the expected future performance of HPS and UICI,
respectively. We have not assumed any responsibility for the independent
verification of any such information or of the projections provided to us and we
have further relied upon the assurances of the senior managements of HPS and
UICI that they are unaware of any facts that would make the information or
projections provided to us incomplete or misleading. Notwithstanding our
reliance on the projections provided to us and on the representations made to us
by the managements of HPS and UICI with respect to such projections, in the
course of our analyses for the purposes of rendering this opinion, we have
considered the valuation implications of more conservative projection scenarios
for both HPS and UICI. In arriving at our opinion, we have not performed or
obtained any independent appraisal of the assets or liabilities of HPS and UICI,
nor have we been furnished with any such appraisals. During the course of our
engagement, we were asked by the Board of Directors of HPS to solicit
indications of interest from various third parties regarding a transaction with
HPS, and we have considered the results of such solicitation in rendering our
opinion. Our opinion is necessarily based on economic, market and other
conditions, and the information made available to us, as of the date hereof. We
have assumed that the Merger will qualify as a tax-free "reorganization" within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

We do not express any opinion as to the price or range of prices at which the
shares of common stock of HPS and UICI may trade subsequent to the announcement
of the proposed Merger or as to the price or range of prices at which the shares
of common stock of UICI may trade subsequent to the consummation of the Merger.

We have acted as a financial advisor to HPS in connection with the Merger and
will receive a fee for such services. In the ordinary course of business, Bear
Stearns may actively trade the equity and debt securities of HPS and/or UICI for
our own account and for the account of our customers and, accordingly, may at
any time hold a long or short position in such securities.

It is understood that this letter is intended for the benefit and use of the
Board of Directors of HPS and does not constitute a recommendation to the Board
of Directors of HPS or any holders of HPS' common stock as to how to vote in
connection with the Merger. This opinion does not address HPS' underlying
business decision to pursue the Merger. This letter is not to be used for any
other purpose, or reproduced, disseminated, quoted or referred to at any time,
in whole or in part, without our prior written consent; provided, however, that
this letter may be included in its entirety in any proxy statement / prospectus
to be distributed to holders of HPS common stock in connection with the Merger.

Based on and subject to the foregoing, it is our opinion that, as of the date
hereof, the Exchange Ratio to be provided for in the Merger is fair, from a
financial point of view, to the Shareholders of HPS.

ITEM 22.   UNDERTAKINGS

The undersigned Registrant hereby undertakes:

That, for purposes of determining any liability under the Securities Act, each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities and Exchange Act of 1934, as amended (the "Exchange
Act") (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this 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.

That, prior to any public reoffering of the securities registered hereunder
through use of a prospectus that is a part of this Registration Statement by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.

That every prospectus: (i) that is filed pursuant to the paragraph immediately
preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of
the Securities Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to this
Registration Statement and will not be used until such amendment is effective,
and that, for purposes of determining any liability under the Securities Act,
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 the time shall be deemed to be the initial bona fide offering
thereof.

Insofar as indemnification for liabilities arising under the Securities Act 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 Commission, such indemnification is against
public policy as expressed in the Securities 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 or 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 Securities Act and will be governed by the final
adjudication of such issue.

                                      II-3
<PAGE>

To respond to requests for information that is incorporated by reference into
the prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one
business day of receipt of such request, and to send the incorporated documents
by first class mail or other equally prompt means. This includes information
contained in documents filed subsequent to the effective date of this
Registration Statement through the date of responding to the request.

To supply, by means of a post-effective amendment, all information concerning a
transaction and the company being acquired involved therein that was not the
subject of and included in this Registration Statement when it became effective.

Ladies and Gentlemen:

         I am Executive Vice President and General Counsel of UICI, a Delaware
corporation (the "Company"), and am issuing this opinion in connection with the
registration of ___________ shares of Common Stock, $0.01 par value per share,
of the Company (the "Shares"), to be issued by the Company pursuant to a

         I have examined originals or certified or photostatic copies of such
records of the Company, certificates of officers of the Company and public
officials and such other documents as I have deemed relevant or necessary as the
basis of the opinion set forth below in this letter. In such examination, I have
assumed the genuineness of all signatures, the conformity to original documents
submitted as certified or photostatic copies, and the authenticity of originals
of such latter documents. Based on the foregoing, I am of the following opinion:

                  The Shares have been duly authorized and, when issued by the
                  Company in the manner contemplated in the Registration
                  Statement, will be validly issued, fully paid and
                  nonassessable.

         I hereby consent to the filing of this opinion as Exhibit 5.01 to the
Registration Statement and the reference to me under the heading "Legal
Opinions" in the Proxy Statement/Prospectus constituting part of the
Registration Statement. In giving such consent, I do not thereby admit that I am
in the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the rules and regulations of the
Commission promulgated thereunder.

                                   Sincerely,







                                                                    Exhibit 23.2

We consent to the reference to our firm under the caption "Experts" in the Proxy
Statement of HealthPlan Services Corporation that is made a part of the
