Dear Stockholder:
 
     You are cordially invited to attend a Special Meeting of Stockholders
("Special Meeting") of Medicus Systems Corporation, a Delaware corporation
("Medicus"), to be held at      a.m., on             , 1998 at Medicus'
executive offices, third floor auditorium, One Rotary Center, Evanston,
Illinois.
 
     At the Special Meeting, you will be asked to vote upon the approval and
adoption of the Agreement and Plan of Reorganization, dated as of November 9,
1997 (the "Merger Agreement"), by and among QuadraMed Corporation, a Delaware
corporation ("QuadraMed") and Medicus. Pursuant to the terms of the Merger
Agreement, a wholly owned subsidiary of QuadraMed will be merged with and into
Medicus (the "Merger"). The consummation of the Merger will result in, among
other things, the cancellation, extinguishment and conversion of the outstanding
shares of the common stock, par value $.01 per share, of Medicus (the "Medicus
Common Stock") into the right to receive any of (i) a cash payment of $7.50 per
share of Medicus Common Stock, (ii) 0.3125 shares of common stock, par value
$.01 per share, of QuadraMed (the "QuadraMed Common Stock") for each share of
Medicus Common Stock, subject to adjustment and certain limitations as provided
in the Merger Agreement, or (iii) a combination of cash and QuadraMed Common
Stock (collectively, the "Merger Consideration"). As a result of the Merger,
each share of Medicus Common Stock (other than shares owned by Medicus or
QuadraMed) will be canceled and extinguished and be converted automatically into
the right to receive the Merger Consideration, and Medicus will become a wholly
owned subsidiary of QuadraMed. The proposed Merger is described in the
accompanying Proxy Statement/ Prospectus, the forepart of which includes a
summary of the terms of the Merger and certain other information relating to the
proposed transaction.
 
     The approval and adoption of the Merger Agreement requires the affirmative
vote of holders of at least a majority of the outstanding shares of Medicus
Common Stock. QuadraMed, which acquired 56.7% of the outstanding shares of
Medicus Common Stock pursuant to stock purchase agreements dated November 9,
1997 with certain Medicus stockholders, is required by the Merger Agreement to
vote or cause to be voted its shares of Medicus Common Stock in favor of
approval and adoption of the Merger Agreement. QuadraMed will vote its shares
for the Merger. No provision has been made in the Merger Agreement which
requires the approval of the Merger by a majority of the shares not owned by
QuadraMed. As a result, QuadraMed owns a sufficient number of shares of Medicus
Common Stock to approve the Merger Agreement and the Merger.
 
     AFTER CAREFUL CONSIDERATION, THE MEDICUS BOARD OF DIRECTORS HAS UNANIMOUSLY
DETERMINED THAT THE TERMS OF THE MERGER AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED THEREBY ARE FAIR TO, AND IN THE BEST INTERESTS OF, THE MEDICUS
STOCKHOLDERS. ACCORDINGLY, THE MEDICUS BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS
OF MEDICUS VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
     Stockholders are urged to review carefully the information contained in the
Proxy Statement/Prospectus prior to deciding how to vote their shares at the
Special Meeting.
 
     YOUR VOTE IS IMPORTANT. Whether or not you expect to attend the Special
Meeting in person, please complete, sign and promptly return the enclosed proxy
card in the enclosed postage-prepaid envelope to assure representation of your
shares. You may revoke your proxy at any time before it has been voted, and if
<PAGE>   5
 
you attend the Special Meeting you may vote in person, even if you previously
returned your proxy card. Your prompt cooperation will be greatly appreciated.
 
     WHETHER OR NOT YOU PLAN TO VOTE IN FAVOR OF THE APPROVAL OF THE MERGER
AGREEMENT, YOU SHOULD COMPLETE, DATE, SIGN AND RETURN THE ENCLOSED FORM OF
ELECTION TO THE EXCHANGE AGENT IN THE ENCLOSED PRE-ADDRESSED POSTAGE-PREPAID
ENVELOPE. FAILURE TO RETURN A PROPERLY COMPLETED AND EXECUTED FORM OF ELECTION
TO THE EXCHANGE AGENT BY THE ELECTION DEADLINE (AS DEFINED IN THE ACCOMPANYING
PROXY STATEMENT/PROSPECTUS) WILL BE TREATED AS A NON-ELECTION (AS DEFINED IN THE
ACCOMPANYING PROXY STATEMENT/PROSPECTUS) AND RESULT IN YOUR RECEIVING, SUBJECT
TO CERTAIN ALLOCATION PROCEDURES, SHARES OF QUADRAMED COMMON STOCK IN RESPECT OF
YOUR SHARES OF MEDICUS COMMON STOCK. AN ELECTION TO RECEIVE CASH OR QUADRAMED
COMMON STOCK IN RESPECT OF ALL OR PART OF YOUR SHARES OF COMPANY COMMON STOCK
WILL NOT CONSTITUTE A VOTE IN FAVOR OF THE APPROVAL OF THE MERGER AGREEMENT.
 
     The Board of Directors and management of Medicus appreciate your continued
support. If you need assistance in completing your proxy card or form of
election and letter of transmittal, or if you have any questions about the Proxy
Statement/Prospectus, please feel free to contact the undersigned at (847)

                            ------------------------
 
     This Proxy Statement/Prospectus is being furnished to the holders of common

          a.m., local time, at Medicus' executive offices, third floor
auditorium, One Rotary Center, Evanston, Illinois, including any adjournments or
postponements thereof (the "Special Meeting").
 
     This Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") into Medicus of a wholly owned subsidiary ("Merger Sub") of QuadraMed
Corporation ("QuadraMed") pursuant to the Agreement and Plan of Reorganization,
dated as of November 9, 1997 (the "Merger Agreement"), by and among QuadraMed

QuadraMed under the Securities Act of 1933, as amended (the "Securities Act"),
relating to the shares of QuadraMed Common Stock issuable in connection with the
Merger.
 
     Upon the consummation of the Merger, Medicus will become a wholly owned
subsidiary of QuadraMed and each share of Medicus Common Stock issued and

certain limitations as provided in the Merger Agreement or (iii) a combination
of cash and QuadraMed Common Stock. If the QuadraMed Stock Value (as defined in
"THE MERGER -- General") is less than $20.40, then QuadraMed may, at its sole
discretion, elect to have all or any portion of the shares of Medicus Common
Stock converted into cash. QuadraMed is obligated to issue no more than
1,800,000 shares of QuadraMed Common Stock pursuant to the Merger and pursuant
to the exercise of warrants held by certain former stockholders of Medicus,
which shares are subject to pro rata allocation in the event stock elections by
Medicus stockholders and warrant exercises exceed the share limitation.
Consummation of the Merger is subject to various conditions, including the
affirmative vote of holders of a majority of the outstanding shares of Medicus
Common Stock entitled to vote at the Special Meeting. See "SUMMARY," "THE STOCK
PURCHASE AGREEMENTS AND WARRANTS," "THE MERGER AGREEMENT" and ANNEX A to this

     QuadraMed and Medicus have entered into an Agreement and Plan of
Reorganization, dated as of November 9, 1997 (the "Merger Agreement"), a copy of
which is attached hereto as Annex A, whereby a wholly owned subsidiary of

a result of the Merger, Medicus will become a wholly owned subsidiary of
QuadraMed. See "THE MERGER."
<PAGE>   16
 
MERGER CONSIDERATION
 
     At the Effective Time, each share of Medicus Common Stock issued and
outstanding (other than any shares of Medicus Common Stock owned by Medicus as
treasury stock or owned by QuadraMed) will be canceled and extinguished and be
converted automatically into the right to receive (i) $7.50 in cash, without
interest (the "Per Share Cash Amount"); or (ii) 0.3125 shares of QuadraMed
Common Stock (the "Exchange Ratio"), subject to adjustment and limitations as
described below; or (iii) a combination of shares of QuadraMed Common Stock and
cash. The Exchange Ratio is subject to the following adjustments: (1) if the
QuadraMed Stock Value (as defined below) exceeds $27.60, then the Exchange Ratio
shall be the quotient obtained by dividing (A) $8.625 by (B) the QuadraMed Stock
Value, and (2) if the QuadraMed Stock Value is less than $24.00, then the
Exchange Ratio shall be the quotient obtained by dividing (A) $7.50 by (B) the
QuadraMed Stock Value. Additionally, if the QuadraMed Stock Value is less than
$20.40, then QuadraMed may, at its sole discretion, elect to have all or any
portion of the shares of Medicus Common Stock converted into the Per Share Cash
Amount (the "QuadraMed Cash Election"). In the event of a QuadraMed Cash
Election in which less than all of the outstanding shares of Medicus Common
Stock will be converted into cash, the shares of Medicus Common Stock to be
converted into cash as a result of the QuadraMed Cash Election will be selected
pro rata according to the number of shares with respect to which a Stock
Election (as defined in "THE MERGER -- General") has been made. The amounts paid
in the Merger in exchange for shares of Medicus Common Stock shall be referred
to herein as the "Merger Consideration." For purposes hereof, the "QuadraMed
Stock Value" shall be equal to the average of the closing prices of QuadraMed
Common Stock during the fifteen (15) days prior to the second day prior to the
date of the Special Meeting. See "THE MERGER AGREEMENT -- Terms of the Merger."
 
PRIOR PURCHASE OF MEDICUS COMMON STOCK BY QUADRAMED
 
     On November 9, 1997, QuadraMed and certain stockholders of Medicus,
including certain members of the Medicus Board of Directors (the "Selling
Stockholders") entered into Stock Purchase Agreements pursuant to which
QuadraMed acquired 56.7% of the outstanding Medicus Common Stock. In
consideration for the sale of the Medicus Common Stock to QuadraMed, QuadraMed
agreed to pay to the Selling Stockholders $7.50 per share, in cash, without
interest, together with a warrant (the "Warrant") entitling the Selling
Stockholders to acquire 0.3125 shares of QuadraMed Common Stock for each share
of Medicus Common Stock sold at a price of $24.00 per share (the closing price
of the QuadraMed Common Stock on the last trading day prior to the execution of
the Stock Purchase Agreements), subject to adjustments and certain limitations.
The aggregate purchase price paid by QuadraMed to the Selling Stockholders was
approximately $23.3 million in cash plus Warrants to purchase an aggregate of
972,220 shares of QuadraMed Common Stock. See "THE STOCK PURCHASE AGREEMENTS
AND WARRANTS."
 
LIMITATION ON SHARES ISSUABLE
 
     In no event shall the aggregate number of shares of QuadraMed Common Stock
which QuadraMed is obligated to issue (i) upon the exercise of Warrants and (ii)
in exchange for outstanding shares of Medicus Common Stock exceed a total of
1,800,000 shares. In the event that the aggregate number of shares of QuadraMed
Common Stock that holders of Warrants and holders of Medicus Common Stock have
elected to receive as described in clauses (i) and (ii) in the immediately
preceding sentence exceeds 1,800,000 shares, QuadraMed shall only be required to
issue 1,800,000 shares of QuadraMed Common Stock and such holders shall be
entitled to receive shares of QuadraMed Common Stock equal to each holder's pro
rata portion of the total amount of shares issued by QuadraMed as described in
clauses (i) and (ii), based on the total number of shares each holder elected to
receive and in the case of clause (ii), such holders shall receive the remaining
Merger Consideration to which they are entitled in cash. See "THE MERGER
AGREEMENT -- Limitation on Shares Issuable."
 
TREATMENT OF STOCK OPTIONS AND OUTSTANDING WARRANTS
 
     At the Effective Time, the obligations under the Medicus Stock Option Plans
(as defined in "THE MERGER AGREEMENT -- Terms of the Merger") and the Stock
Subscription Warrant dated March 1,
 
                                        2
<PAGE>   17
1996 issued by Medicus to TriHealth, Inc. (the "TriHealth Warrant") will be
assumed by QuadraMed. Each option so assumed by QuadraMed shall continue to
have, and be subject to, the same terms and conditions set forth in the Medicus
Stock Option Plans and the TriHealth Warrant shall continue to have, and be
subject to, the same terms and conditions set forth therein, immediately prior
to the Effective Time, except that (i) each of the assumed options and warrants
will be exercisable for that number of whole shares of QuadraMed Common Stock
equal to the product of the number of shares of Medicus Common Stock that were
issuable upon exercise of such option or warrant immediately prior to the
Effective Time multiplied by 0.3565, rounded down to the nearest whole number
of shares of QuadraMed Common Stock, (ii) an aggregate of 728,000 options
granted under the Medicus 1994 Directors' Stock Option Plan, the Medicus 1996
C.E.O. Stock Option Plan, the Medicus 1996 C.E.O. Replacement Stock Option Plan
and the Medicus 1996 C.E.O. Special Stock Option Plan (the "Director Options")
shall be fully vested and  shall remain exercisable for a period of three years
after (a) termination of employment,in the case of options held by Mr. Sommers
and (b) the Effective Time in the case of Director Options and (iii) the per
share exercise price for the shares of QuadraMed Common Stock issuable upon
exercise of such assumed option or warrant will be equal to the quotient
determined by dividing the exercise price per share of Medicus Common Stock at
which such option or warrant was exercisable immediately prior to the Effective

                                SPECIAL FACTORS
 
     Holders of Medicus Common Stock, in voting on the Merger, should consider
special factors associated with the Merger. See "SPECIAL FACTORS."
 
BACKGROUND OF THE MERGER
 
     For a description of events leading to the adoption and approval of the
Merger Agreement by the Boards of Directors of QuadraMed and Medicus, see
"SPECIAL FACTORS -- Background of the Merger."
 
PURPOSE AND STRUCTURE OF THE MERGER
 
     The purpose of the Merger is for QuadraMed to acquire the entire equity
interest in Medicus. Because holders of Medicus Common Stock have the right to
elect to receive QuadraMed Common Stock, they will have the opportunity to
maintain an indirect equity interest in Medicus.
 
SOURCE AND AMOUNT OF FUNDS
 
     If all Medicus stockholders elect to receive cash in the Merger and
assuming no current Medicus option holders exercise options to purchase Medicus
Common Stock, approximately $18.1 million will be required to pay such
consideration. In addition, QuadraMed will pay fees and expenses of
approximately $          in connection with the Merger. The cash required in
connection with the Merger will be provided by current cash resources of
QuadraMed.
 
     In connection with its purchase of 56.7% of the outstanding shares of the
Medicus Common Stock, QuadraMed paid cash to the Selling Stockholders of
approximately $23.3 million, which amount was funded by QuadraMed's existing
cash resources.
 
CERTAIN EFFECTS OF THE MERGER; PLANS FOR THE COMPANY AFTER THE MERGER
 
     Following the Merger, QuadraMed will own 100% of the outstanding capital
stock of the Surviving Corporation (as defined in "THE MERGER AGREEMENT -- The
Merger"). As such, QuadraMed will be the direct beneficiary of any future
earnings and growth of the Surviving Corporation, and will have the ability to
benefit from any divestitures, strategic acquisitions or other corporate
opportunities that may be pursued by the Surviving Corporation in the future.
Upon the consummation of the Merger, each share of Medicus Common Stock issued
and outstanding immediately prior to the Effective Time (other than any shares
of Medicus Common Stock owned by Medicus or QuadraMed) will be cancelled and
extinguished and be converted into the right to receive the Merger Consideration
and the stockholders of Medicus will cease to have any direct ownership interest
in Medicus.
 
     As a result of the Merger, (i) the Surviving Corporation will be privately
held; (ii) there will be no market for the Medicus Common Stock; (iii) the
Medicus Common Stock will cease to be listed on the Nasdaq National Market; and
(iv) the registration of the Medicus Common Stock under the Exchange Act will be
terminated and Medicus will no longer be required to file periodic reports with
the Commission.

     See "SPECIAL FACTORS -- Certain Effects of the Merger; Plans for the
Company After the Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Board of Directors of Medicus with
respect to the Merger, holders of Medicus Common Stock should be aware that
certain members of Medicus' management and members of the Medicus Board of
Directors have certain interests in the Merger, in addition to those of Medicus'
stockholders generally. The Board of Directors of Medicus was aware of these
interests when it considered and approved the Merger and the Merger Agreement.
 
     Upon consummation of the Merger, QuadraMed has agreed to enter into an
employment agreement with Patrick C. Sommers, President and Chief Executive
Officer of Medicus. In addition, Mr. Sommers has received a bonus payment of
$750,000 from Medicus in connection with QuadraMed's acquisition of Medicus. See
"SPECIAL FACTORS -- Interests of Certain Persons in the Merger" for a
description of such bonus and employment agreement.
 
     Pursuant to the Merger Agreement, the obligations under the Medicus Stock
Option Plans and the TriHealth Warrant will be assumed by QuadraMed. Each option
so assumed by QuadraMed shall continue to have, and be subject to, the same
terms and conditions set forth in the Medicus Stock Option Plans and the
TriHealth Warrant, shall continue to have, and be subject to, the same terms and
conditions set forth therein, immediately prior to the Effective Time, except
that (i) each of the assumed options and warrants will be exercisable for that
number of whole shares of QuadraMed Common Stock equal to the product of the
number of shares of Medicus Common Stock that were issuable upon exercise of
such option or warrant immediately prior to the Effective Time multiplied by
0.3565, rounded down to the nearest whole number of shares of QuadraMed Common
Stock, (ii) Director Options shall be fully vested and shall remain exercisable
for a period of three years after (a) termination of employment, in the case of
options held by Mr. Sommers and (b) the Effective Time in the case of other
Director Options and (iii) the per share exercise price for the shares of
QuadraMed Common Stock issuable upon exercise of such assumed option or warrant
will be equal to the quotient determined by dividing the exercise price per
share of Medicus Common Stock at which such option or warrant was exercisable
immediately prior to the Effective Time by 0.3565, rounded up to the nearest
whole cent.
 
     At the Effective Time of the Merger, QuadraMed will purchase and cancel the
Jelinek Warrants in exchange for shares of QuadraMed Common Stock with an
aggregate value of $1.12 million. The number of shares of QuadraMed Common Stock
issuable in exchange for the Jelinek Warrants will be determined by dividing
$1.12 million by the QuadraMed Stock Value as defined in the Merger Agreement.
If at the Effective Time of the Merger, the QuadraMed Stock Value exceeds
$27.60, then the number of shares of QuadraMed Common Stock issuable upon
cancellation of the Jelinek Warrants shall be equal to $1.12 million divided by
$27.60. If at the Effective Time of the Merger, the QuadraMed Stock Value is
less than $20.40, then the number of shares of QuadraMed Common Stock issuable
upon cancellation of the Jelinek Warrants shall be equal to $1.12 million
divided by $20.40.
 
     Concurrent with the execution of the Merger Agreement, certain stockholders
of Medicus (including Richard C. Jelinek, William G. Brown, Jon E.M. Jacoby,
Gail L. Warden and Dorsey R. Gardner, all of whom are members of the Medicus
Board of Directors) sold their shares of Medicus Common Stock to QuadraMed
pursuant to stock purchase agreements, each dated as of November 9, 1997. The
consideration paid by QuadraMed for such shares was $7.50 per share in cash plus
a warrant to purchase 0.3125 shares of QuadraMed Common Stock for each share of
Medicus Common Stock sold. The warrants are exercisable only at the Effective
Time of the Merger at a price of $24.00 per share (the closing price of the
QuadraMed Common Stock on the last trading day prior to the execution of the
stock purchase agreements), subject to
 
                                        5
<PAGE>   20
 
certain adjustments and limitations. See "SPECIAL FACTORS -- Interests of
Certain Persons in the Merger" and "THE STOCK PURCHASE AGREEMENTS AND WARRANTS."
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The receipt of the Merger Consideration for shares of Medicus Common Stock
will be a taxable transaction for U.S. federal income tax purposes and may be a
taxable transaction for foreign, state and local income tax purposes as well. A
Medicus stockholder will generally recognize gain or loss equal to the
difference between (i) the amount of cash, and, in the case of Medicus
stockholders receiving QuadraMed Common Stock, the fair market value of
QuadraMed Common Stock that the stockholder receives as a result of the Merger
and (ii) the stockholder's adjusted tax basis in the shares of Medicus Common
Stock that the stockholder exchanges in the Merger. Medicus will not recognize
any gain or loss as a result of the Merger for U.S. federal income tax purposes.
See "SPECIAL FACTORS -- Federal Income Tax Consequences."
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a purchase for financial reporting
purposes in accordance with generally accepted accounting principles ("GAAP").
This method will require the allocation of the purchase price to the various
assets acquired and liabilities assumed based on the fair market values of those
assets and liabilities.
 
     QuadraMed received an appraisal of certain intangible assets which will be
acquired in the Merger which indicated that approximately $35,000,000 of the
intangible assets to be acquired consist of in-process research and development.
In the opinion of management, the acquired in-process research and development
had not yet reached technological feasibility and had no alternative future use.
Accordingly, QuadraMed expects to record a non-recurring charge of approximately
$35,000,000 in its fourth quarter ended December 31, 1997. The remaining
intangible assets are expected to be amortized over a seven-year period.
 
CERTAIN LEGAL MATTERS
 
     No federal or state regulatory requirements or approvals (other than those
which arose in connection with the registration of QuadraMed Common Stock to be
issued in the Merger and certain notice filings after the Effective Time) must
be complied with or obtained in connection with the Merger.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
     All QuadraMed Common Stock issued in connection with the Merger will be
freely transferable, except that any QuadraMed Common Stock received by persons
who are deemed to be "affiliates" (as such term is defined under the Securities
Act) of Medicus or QuadraMed prior to the Merger may be sold by them only in
transactions permitted by the resale provisions of Rule 145 under the Securities
Act with respect to affiliates of Medicus, or Rule 144 under the Securities Act
with respect to persons who are or become affiliates of QuadraMed, or as
otherwise permitted under the Securities Act. See "SPECIAL FACTORS -- Federal
Securities Law Consequences."
 
LISTING
 
     It is a condition to the obligations of QuadraMed and Medicus to consummate
the Merger that application shall have been made to the Nasdaq National Market
to list the shares of QuadraMed Common Stock to be issued in connection with the
Merger.
 
APPRAISAL RIGHTS
 
     Record holders of Medicus Common Stock are entitled to appraisal rights
under Section 262 ("Section 262") of the Delaware General Corporation Law (the
"DGCL"), which is reprinted in its entirety as Annex C to this Proxy
Statement/Prospectus. A person having a beneficial interest in shares of Medicus
Common Stock held of record in the name of another person, such as a broker or
nominee, must act promptly
 
                                        6
<PAGE>   21
 
to cause the record holder to follow the steps summarized below properly and in
a timely manner to perfect the appraisal rights provided under Section 262.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Special Meeting, not less than 20
days prior to the meeting, a constituent corporation must notify each of the
holders of its stock (who was a stockholder on the record date for such meeting)
for which appraisal rights are available that such appraisal rights are
available and include in each such notice a copy of Section 262. THIS PROXY
STATEMENT/ PROSPECTUS SHALL CONSTITUTE SUCH NOTICE TO THE RECORD HOLDERS OF
MEDICUS COMMON STOCK THAT APPRAISAL RIGHTS ARE AVAILABLE. ANY SUCH STOCKHOLDER
WHO WISHES TO EXERCISE SUCH APPRAISAL RIGHTS SHOULD REVIEW THE FOLLOWING
DISCUSSION AND ANNEX -- C CAREFULLY, BECAUSE FAILURE TO TIMELY AND STRICTLY
COMPLY WITH THE PROCEDURES SPECIFIED MAY RESULT IN THE LOSS OF APPRAISAL RIGHTS
UNDER THE DGCL. See "SPECIAL FACTORS -- Appraisal Rights" and ANNEX C.
 
                              THE SPECIAL MEETING
 
TIME, PLACE AND DATE
 
     A special meeting of the stockholders of Medicus will be held at Medicus'
executive offices, third floor auditorium, One Rotary Center, Evanston,
Illinois, on             , 1998, at           a.m., local time (including any
and all adjournments or postponements thereof, the "Special Meeting").
 
PURPOSE OF THE MEETING
 
     At the Special Meeting, holders of Medicus Common Stock will consider and
vote upon a proposal to approve and adopt the Merger Agreement and approve the
Merger. As a result of the Merger, Medicus will become a wholly owned subsidiary
of QuadraMed. Stockholders of Medicus will also consider and vote upon any other
matter that may properly come before the Special Meeting. See "THE SPECIAL
MEETING."
 
VOTE REQUIRED; RECORD DATE
 
     Approval of the Merger Agreement and the consummation of the Merger will
require the affirmative vote of the holders of a majority of the outstanding
shares of Medicus Common Stock entitled to vote at the Special Meeting. Holders
of Medicus Common Stock are entitled to one vote per share. Only holders of
Medicus Common Stock at the close of business on             , 1998 (the
"Medicus Record Date") will be entitled to notice of and to vote at the Special
Meeting. On             , 1998, there were           shares of Medicus Common
Stock outstanding and entitled to vote. See "THE SPECIAL MEETING."
 
     QuadraMed, which acquired 56.7% of the outstanding shares of Medicus Common
Stock on November 9, 1997 pursuant to stock purchase agreements with certain
stockholders of Medicus, will vote its shares of Medicus Common Stock in favor
of approval and adoption of the Merger Agreement and the transactions
contemplated thereby. As a result, QuadraMed's affirmative vote for approval and
adoption of the Merger Agreement is sufficient to approve the Merger. No
provision has been made in the Merger Agreement which requires that the Merger
be approved by a majority of the unaffiliated Medicus stockholders. See "THE
STOCK PURCHASE AGREEMENTS AND WARRANTS," "THE SPECIAL MEETING" and "THE MERGER."
 
                RECOMMENDATION OF THE MEDICUS BOARD OF DIRECTORS
 
     THE MEDICUS BOARD OF DIRECTORS (I) UNANIMOUSLY BELIEVES THE TERMS AND
CONDITIONS OF THE MERGER AGREEMENT AND THE MERGER ARE FAIR TO, AND IN THE BEST

OF THE MERGER AGREEMENT AND THE MERGER AND (III) UNANIMOUSLY RECOMMENDS THAT THE
MEDICUS STOCKHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT AND
CONSUMMATION OF THE MERGER. THE PRIMARY FACTORS CONSIDERED AND RELIED UPON BY
THE MEDICUS BOARD OF

                                  RISK FACTORS
 
     Holders of Medicus Common Stock should consider risks associated with the
Merger and with holding QuadraMed Common Stock before voting to approve and
adopt the Merger Agreement and the Merger. A copy of the Merger Agreement is
attached as Annex A to this Proxy Statement/Prospectus. See "RISK FACTORS."
 
                           THE QUADRAMED COMMON STOCK
 
     At December 31, 1997, the authorized capital stock of QuadraMed consisted
of: (i) 20,000,000 shares of common stock, par value $.01 per share, of which
11,916,097 shares were issued and outstanding and 2,425,129 shares were issuable
with respect to options, warrants, convertible debt and similar rights to
acquire shares of QuadraMed Common Stock; and (ii) 5,000,000 shares of preferred
stock, par value $.01 per share, of which no shares were issued and outstanding.
It is anticipated that at the Effective Time, assuming issuance of 1,800,000
shares of QuadraMed Common Stock pursuant to the Merger Agreement and the
exercise of the Warrants, approximately 1,800,000 shares of QuadraMed Common
Stock will be issued to the holders of Medicus Common Stock and the Warrants,
and an additional 570,827 shares of QuadraMed Common Stock will be issuable upon
the exercise of options which were previously granted under the Medicus Stock
Option Plans and the TriHealth Warrant. In addition, up to 54,902 shares of
QuadraMed Common Stock will be issued upon the purchase and cancellation of the
Jelinek Warrants. The 2,425,729 shares of QuadraMed Common Stock issuable in
connection with these transactions would represent approximately 14.5% of
QuadraMed's outstanding Common Stock (on a fully-diluted basis) following the
Merger based on QuadraMed's outstanding Common Stock and other rights to aquire
QuadraMed Common Stock outstanding as of December 31, 1997. QuadraMed Common
Stock trades on the Nasdaq National Market under the symbol "QMDC."

               COMPARATIVE HISTORICAL AND COMBINED PER SHARE DATA
 
     The following historical earnings (loss) per share and stockholders' equity
per share of QuadraMed and Medicus, and pro forma loss per share and
stockholders' equity per share give effect to the Merger as though it occurred
at the beginning of each period for earnings (loss) per share purposes and as of
the indicated balance sheet date for purposes of stockholders' equity per share
information. The equivalent pro forma loss per share and stockholders' equity
per share is based upon an assumed share exchange ratio of 0.3125 provided by
the Merger Agreement as discussed in the footnotes below. The comparative
historical and combined per share data are not necessarily indicative of the
results that actually would have occurred if the Merger had been completed at
the beginning of the periods presented or which may be expected in the future.
The combined financial information should be read in conjunction with the
historical consolidated financial statements of QuadraMed and Medicus
incorporated by reference herein and in conjunction with the Unaudited Pro Forma
Combined Condensed Financial Statements of QuadraMed and Medicus included

(1) The Medicus equivalent pro forma combined loss per share and equivalent pro
    forma stockholders' equity per share represents the pro forma combined loss
    per share and pro forma combined stockholders' equity per share,
    respectively, multiplied by an assumed share exchange ratio of 0.3125 shares
    of QuadraMed common stock for each share of Medicus common stock.
 
(2) The historical stockholders' equity per share is computed by dividing
    stockholders' equity by the number of shares of common stock outstanding at
    the end of the period.
 
(3) The pro forma combined stockholders' equity per share is computed by
    dividing the pro forma stockholders' equity by the pro forma number of
    shares of common stock outstanding at the end of each period.

                       QUADRAMED SELECTED FINANCIAL DATA
 
     The following table sets forth the selected financial data of QuadraMed for
each fiscal year in the five-year period ended December 31, 1996 and for the
nine months ended September 30, 1997. Such data for the annual periods have been
derived from, and should be read in conjunction with, QuadraMed's audited
consolidated financial statements contained in QuadraMed's Annual Report on Form
10-KSB, and amendment thereto, for the fiscal year ended December 31, 1996 and
incorporated herein by reference. Such data for the nine months ended September
30, 1997 have been derived from, and should be read in conjunction with,
QuadraMed's unaudited consolidated financial statements contained in QuadraMed's
Form 10-Q for the period then ended and incorporated herein by reference. See
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and "AVAILABLE INFORMATION."
Interim unaudited data reflect, in the opinion of management, all adjustments
(consisting of normal recurring adjustments) necessary to present fairly the
information set forth therein.
 
     Results of operations for the nine months ended September 30, 1997 are not
necessarily indicative of results of operations for the entire year or
predictive of future periods. QuadraMed's development and expansion activities,
including acquisitions, during the periods shown below materially affect the
comparability of this data from one period to another.

                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
     The rights of Medicus stockholders currently are governed by Delaware law,
Medicus' Amended and Restated Certificate of Incorporation, and Medicus' Bylaws.
Upon consummation of the Merger, stockholders of Medicus may become stockholders
of QuadraMed, which is also a Delaware corporation, and their rights as
stockholders of QuadraMed would be governed by Delaware law, QuadraMed's Second
Amended and Restated Certificate of Incorporation ("Certificate of
Incorporation") and QuadraMed's Bylaws. For a comparison of the rights of
Medicus stockholders and the rights of QuadraMed stockholders, see "COMPARISON
OF STOCKHOLDER RIGHTS."
 
                              RECENT DEVELOPMENTS
 
     On December 29, 1997, QuadraMed acquired Rothenberg Health Systems Inc.
("Rothenberg"), a provider of health care information systems, and Healthcare
Research Affiliates ("HRA"), a consulting company that specializes in HEDIS
reporting, from Resource Health Partners, L.P. ("RHP") in two related merger
transactions (referred to herein as the "RHP Mergers"). In the RHP Mergers,
QuadraMed issued an aggregate of 1,588,701 shares of QuadraMed Common Stock,
valued at approximately $37.0 million. The transaction will be treated as a
pooling of interests for accounting purposes. QuadraMed has agreed to register
such shares for resale under the Securities Act. See "RISK FACTORS -- Shares
Eligible for Future Sale; Possible Volatility of Stock Price; Low Trading
Volume."

     Rothenberg is a provider of health care information systems designed to
enable health care providers to efficiently manage the risks associated with
managed care contracts. Rothenberg has a client base of more than 300 IPAs,
medical groups, hospitals, MSOs, PHOs and integrated delivery systems that
employ or contract with an estimated 40,000 providers of care, who, in turn,
serve over 8,000,000 enrollees in 35 states. Rothenberg's primary product is
EZ-CAP(R), a software product that is designed to validate enrollee eligibility,
adjudicate claims based on specific benefit structures and ensure the accurate
processing and payment of claims. See "RISK FACTORS -- Integration of Acquired
Companies Into QuadraMed" and "-- Risks Associated with Acquisitions; Need to
Manage Changing Operations."

                                  RISK FACTORS
 
     Holders of Medicus Common Stock should consider carefully all of the
information contained in this Proxy Statement/Prospectus, including the
following risk factors in evaluating the Merger:
 
HISTORY OF OPERATING LOSSES; UNCERTAIN PROFITABILITY
 
     QuadraMed incurred net losses of $4.9 million and $9.4 million for the
years ended December 31, 1994 and 1995, respectively, and as of September 30,
1997 had an accumulated deficit of $12.3 million. Medicus incurred net losses of
$3.7 million and $4.2 million for the years ended May 31, 1996 and 1997,
respectively, and for the six months ended November 30, 1997, had a net loss of
$1.4 million and an accumulated deficit of $9.3 million. Although QuadraMed
recorded net income of $153,000 and $2.8 million for the year ended December 31,
1996 and the nine months ended September 30, 1997, respectively, these results
do not include the effect of the Medicus and RHP acquisitions. In connection
with the Merger and other acquisitions, QuadraMed has and will incur significant
non-recurring charges and will be required to amortize significant expenses
related to goodwill and other intangible assets in future periods. There can be
no assurance that QuadraMed will be able to achieve or sustain revenue growth or
profitability on a quarterly or annual basis. See "SUMMARY -- QuadraMed Selected
Financial Data," "-- Medicus Selected Financial Data" and "PRO FORMA FINANCIAL
DATA."
 
POTENTIAL VARIABILITY IN QUARTERLY OPERATING RESULTS
 
     QuadraMed's quarterly revenues and operating results have varied
significantly in the past and are likely to vary substantially from quarter to
quarter in the future. Quarterly revenues and operating results may fluctuate as
a result of a variety of factors, including the following: integration of
acquired businesses, variability in demand for QuadraMed's products and
services; the number, timing and significance of announcements and releases of
product enhancements and new products by QuadraMed and its competitors; the
timing and significance of announcements concerning QuadraMed's present or
prospective strategic alliances; the termination of, or a reduction in,
offerings of QuadraMed's products and services; the loss of customers due to
consolidation in the health care industry; delays in product delivery requested
by customers; the length of the sales cycle or the timing of sales; the amount
of new potential contracts at the beginning of any particular quarter; customer
budgeting cycles and changes in customer budgets; investments by QuadraMed in
marketing, sales, research and development, and administrative personnel
necessary to support QuadraMed's anticipated operations; marketing and sales
promotional activities; software defects and other quality factors; and general
economic conditions.
 
     In May 1997, QuadraMed acquired, in exchange for $2.5 million, a 10.2%
equity stake in EDI USA, Inc. ("EDI USA"), an organization owned and established
by thirteen independent Blue Cross and Blue Shield Plans to build and operate an
EDI transaction network to facilitate submission of claims, receipt of
remittances, eligibility verification and other health care transactions. In
addition, QuadraMed entered into an agreement with EDI USA for QuadraMed to
provide EDI processing services. QuadraMed recorded non-recurring charges of
$334,000, $360,000 and $346,000 for each of the first three quarters of 1997,
respectively, related to start-up costs incurred in connection with its
arrangement to provide EDI processing and management services for EDI USA's
transactions. QuadraMed and EDI USA have terminated their business relationship,
and EDI USA repurchased QuadraMed's equity stake in EDI USA for $2.5 million
during the fourth quarter of 1997. As a result of the termination of the
relationship, QuadraMed expects to record a non-recurring charge in the fourth
quarter of 1997 that substantially exceeds the charges reported in the first
three quarters.
 
     The timing of customer purchases is difficult to predict given the complex
procurement decision process associated with most health care providers and
payors. As a result, QuadraMed typically experiences, and Medicus and RHP have
experienced, sales cycles that extend over several quarters for new customers.
QuadraMed expects that these factors will result in variations in quarterly
revenues and operating results. Moreover, QuadraMed's operating expense levels,
which will increase with the addition of the businesses of Medicus and RHP, are
relatively fixed. If revenues are below expectations, net income is likely to be
 
                                       15
<PAGE>   30
 
disproportionately affected. Further, it is likely that in some future quarter
QuadraMed's revenues or operating results will be below the expectations of
securities analysts and investors. In such event, the trading price of
QuadraMed's Common Stock would likely be materially adversely affected.
 
INTEGRATION OF ACQUIRED COMPANIES INTO QUADRAMED
 
     QuadraMed has entered into the Merger Agreement with Medicus and completed
the RHP Mergers with the expectation that the Merger and the RHP Mergers will
result in certain benefits to QuadraMed as the combined company. Realizing the
benefits of the Merger and the RHP Mergers will depend in part upon the
successful integration of the businesses, products and employees of QuadraMed,
RHP and Medicus in an efficient manner, and there can be no assurance that such
integration will not entail substantial costs, delays or other problems or that
such integration will be successfully completed. Combining the companies will
divert the attention of management from other matters and will result in
significant operational and administrative expense. QuadraMed will incur a
significant amortization expense in future periods as a result of the Medicus
acquisition. Any difficulties encountered in the integration process could have
a material adverse effect on the revenues and operating results of the combined
company. In addition, the process of combining the companies could cause the
interruption of, or a disruption in, the business activities of the constituent
companies, which could have a material adverse effect on the operations and
financial performance of the combined company. Even if these companies are
successfully integrated into QuadraMed, the acquired operations may not achieve
sales, productivity and profitability commensurate with QuadraMed's historical
operating results or with projected results of QuadraMed and financial analysts
and investors. Failure to achieve such projected results would have a material
adverse effect on QuadraMed's financial performance, and in turn, on the market
value of the QuadraMed Common Stock. There can be no assurance that the combined
company will realize any of the anticipated benefits of the Merger and the RHP
Mergers or that such acquisitions will enhance QuadraMed's business or financial
performance.
 
DEPENDENCE ON ACQUISITIONS FOR GROWTH
 
     QuadraMed intends to continue to expand in substantial part through
acquisitions of products, technologies and businesses. QuadraMed's ability to
expand successfully through acquisitions depends on many factors, including the
successful identification and acquisition of products, technologies or
businesses and management's ability to effectively negotiate and consummate
acquisitions and integrate and operate the new products, technologies or
businesses. There is significant competition for acquisition opportunities in
QuadraMed's industry, which may intensify due to increasing consolidation in the
health care industry, increasing the costs of capitalizing on acquisition
opportunities. QuadraMed competes for acquisition opportunities with other
companies that have significantly greater financial and management resources
than QuadraMed. The inability to successfully identify appropriate acquisition
opportunities, consummate acquisitions or successfully integrate acquired
products, technologies, operations, personnel or businesses could have a
material adverse effect on QuadraMed's business, financial condition and results
of operations. In addition, acquisitions may divert management's attention from
other business concerns, expose QuadraMed to the risks of entering markets in
which it has no direct prior experience or to risks associated with the market
acceptance of acquired products and technologies, or result in the loss of key
employees of QuadraMed or the acquired company. Moreover, acquisitions
(including the Merger and the RHP Mergers) by QuadraMed may result in
potentially dilutive issuances of equity securities, the incurrence of
additional debt and the recognition of amortization expenses related to goodwill
and other intangible assets, which could have a material adverse effect on its
business, financial condition and results of operations.
 
RISKS ASSOCIATED WITH ACQUISITIONS; NEED TO MANAGE CHANGING OPERATIONS
 
     Acquisitions, including the Medicus Merger and RHP Mergers involve a
number of special risks including, without limitation, managing geographically
dispersed operations, failure of the acquired business to achieve expected
results, failure to retain key personnel of the acquired business, inability to
integrate the new business into existing operations and risks associated with
unanticipated events or liabilities, potential increases in stock compensation
expense and increased compensation expense resulting from newly hired employees;
the
 
                                       16
<PAGE>   31
 
assumption of unknown liabilities, potential disputes with the sellers of one or
more acquired entities, all of which could have a material adverse effect on
QuadraMed's business, results of operations and financial condition.
Additionally, customer dissatisfaction or performance problems at a single
acquired company could have an adverse effect on QuadraMed's reputation and its
sales and marketing initiatives. With the addition of the Medicus and RHP 
businesses, QuadraMed's anticipated future operations may place a strain on its
management systems and resources. QuadraMed expects that it will be required to
continue to improve its financial and management controls, reporting systems and
procedures, and will need to expand, train and manage its work force. There can
be no assurance that QuadraMed will be able to effectively manage these tasks,
and the failure to do so could have a material adverse effect on its business,
financial condition and results of operations.
 
NEED TO EXPAND SALES AND TECHNICAL SUPPORT CAPABILITIES
 
     A substantial percentage of QuadraMed's sales force is currently
inexperienced in selling QuadraMed's products and will remain so for some time.
With the addition of the Medicus and RHP businesses, QuadraMed will need to
commit significant resources to further recruit, train, motivate, manage and
retain sales personnel to support its expanded product and service offerings.
While QuadraMed intends to commit funds to expand its sales organization, there
can be no assurance that QuadraMed will be able to recruit, train, motivate,
manage and retain additional sales personnel or that their activities will
result in additional revenues to QuadraMed. In addition, QuadraMed recognizes
that as its level of sales increases, it will need to expand its technical
support capabilities to service its expanding customer base. Competition for
qualified sales and technical support personnel in the software industry is
intense. Failure by QuadraMed to effectively expand its sales and technical
support capabilities could have a material adverse effect on QuadraMed's
business, financial condition and results of operations.
 
     In addition, QuadraMed intends to develop a national sales force that will
be responsible for particular customers rather than particular products. This
approach will require additional training so that sales personnel may become
more familiar with QuadraMed's broader range of product and service offerings.
There can be no assurance that QuadraMed will be successful in its efforts to
restructure its sales and marketing approach, and any failure to successfully
implement such strategy could have a material adverse effect on its business,
financial condition and results of operations.
 
DEPENDENCE ON KEY PERSONNEL
 
     QuadraMed's performance also depends in significant part upon the continued
service of its executive officers, its product managers and other key sales,
marketing, and development personnel, including such key personnel associated
with Medicus and RHP who must be successfully integrated into QuadraMed's
management team. The loss of the services of any of its executive officers or
the failure to hire or retain other key employees could have a material adverse
effect on QuadraMed's business, financial condition and results of operations.
Additions of new, and departures of existing, personnel can be disruptive and
could have a material adverse effect on QuadraMed's business, financial
condition and results of operations.
 
EXPANDED PRODUCT AND SERVICE OFFERINGS; RELIANCE ON CROSS-SELLING PRODUCTS AND
SERVICES TO CUSTOMERS
 
     With the acquisition of the Medicus and RHP businesses, QuadraMed will 
further expand the complexity of its product and service offerings and broaden
its customer base to include physicians and other non-hospital health care
providers. Prior to the RHP Mergers, QuadraMed's customers were typically
hospitals and other health care providers, and substantially all of QuadraMed's
revenues were derived from the sale of software products and services to
hospitals. With the addition of the Medicus and RHP businesses, QuadraMed
intends to direct its sales and marketing efforts to a broader customer base
than it has previously addressed, including cross-selling its expanded product
and service offerings to existing customers of QuadraMed, Medicus and RHP.
Additionally, QuadraMed intends to continue to expand its product and service
offerings in the future. The addition by QuadraMed to its product and service
offerings presents certain risks and uncertainties involving QuadraMed's
relative unfamiliarity with these new products and services and the market for
such new products and services. There can be no assurance that QuadraMed will be
successful in its cross-selling
 
                                       17
<PAGE>   32
 
efforts or in developing or integrating new products and services, or that its
existing customers will accept such new products and services. Additionally,
there can be no assurance that QuadraMed will retain its existing customers or
the existing customers of Medicus and RHP. In particular, Medicus and RHP have
each released Windows(TM)-based versions of their products and may choose not to
continue to provide technical support for old versions of their product. If the
combined company chooses not to provide this technical support, existing Medicus
and RHP customers may be lost. Any failure by QuadraMed to successfully cross-
sell its products, to develop or integrate new products and services or to
retain existing customers of the combined company could have a material adverse
effect on its business, financial condition and results of operations.
 
THE EFFECT OF QUADRAMED STOCK PRICE FLUCTUATIONS ON THE CONSIDERATION TO BE
RECEIVED BY THE HOLDERS OF MEDICUS COMMON STOCK IN THE MERGER
 
     The price of the QuadraMed Common Stock at the Effective Time may vary
significantly from the price as of the date of execution of the Merger Agreement
or the date hereof or the date of the Special Meeting. These variances may be
due to changes in the business, operations and prospects of QuadraMed or
Medicus, market assessments of the likelihood that the Merger will be
consummated and the timing thereof, the effect of any conditions or restrictions
imposed on or proposed with respect to the combined companies by regulatory
agencies in connection with or following consummation of the Merger, general
market and economic conditions, and other factors. For example, between January
1, 1997 and December 31, 1997, the sales price of the QuadraMed Common Stock
ranged from a high of $27.50 to a low of $6.75. The Exchange Ratio will be
adjusted based on certain changes in the stock price of the QuadraMed Common
Stock: (1) if the QuadraMed Stock Value exceeds $27.60, the Exchange Ratio shall
be the quotient obtained by dividing (A) $8.625 by (B) the QuadraMed Stock
Value, and (2) if the QuadraMed Stock Value is less than $24.00, the Exchange
Ratio shall be the quotient obtained by dividing (A) $7.50 by (B) the QuadraMed
Stock Value. Additionally, if the QuadraMed Stock Value is less than $20.40,
QuadraMed may elect, at its sole discretion, to cause all or any portion of the
Medicus Common Stock to be converted into the Per Share Cash Amount. The
"QuadraMed Stock Value" is equal to the average of the closing prices of
QuadraMed Common Stock during the 15 days prior to the second day prior to the
Special Meeting. Pursuant to the terms of the Merger Agreement, the dollar value
of the QuadraMed Common Stock to be received by the holders of Medicus Common
Stock will not be determined until the Effective Time, and may be substantially
more or less than the value of the QuadraMed Common Stock as of the date of
execution of the Merger Agreement, the date hereof or the date of the Special
Meeting.
 
RISKS RELATED TO HOSPITAL AND MANAGED CARE MARKETS
 
     A substantial portion of QuadraMed's revenues have been and are expected to
be derived from the sale of software products and services to hospitals.
QuadraMed's financial performance is dependent on continued demand for its
products. Consolidation in the health care industry, particularly in the
hospital and managed care markets, could cause a decrease in the number of
potential purchasers of QuadraMed's products and services or the loss of one or
more of QuadraMed's significant customers, including existing customers of
Medicus and RHP, insofar as customers may be acquired by another company that
uses products or services provided by a competitor of QuadraMed, Medicus or RHP.
Any of these occurrences could have a material adverse effect on QuadraMed's
business, financial condition and results of operations. In addition, the
decision to purchase QuadraMed's products often involves the approval of several
members of management of a hospital or health care provider. Consequently, it is
difficult for QuadraMed to predict the timing or outcome of the buying decisions
of customers or potential customers.
 
     The health care industry in the United States is subject to changing
political, economic and regulatory influences that may affect the procurement
practices and operations of health care organizations. QuadraMed believes that
the commercial value and appeal of its products may be adversely affected if the
current health care financing and reimbursement system were to reverse its
current evolution to a managed care model back to a fee-for-service model. In
addition, many of QuadraMed's customers are providing services under capitated
service agreements, and a reduction in the use of capitation arrangements as a
result of regulatory or
 
                                       18
<PAGE>   33
 
market changes could have a material adverse effect on QuadraMed's business,
financial condition and results of operations. During the past several years,
the health care industry has been subject to increasing levels of governmental
regulation of, among other things, reimbursement rates and certain capital
expenditures. Certain proposals to reform the health care system have been and
are being considered by Congress. These proposals, if enacted, could change the
operating environment for QuadraMed's clients in ways that cannot be predicted.
Health care organizations may react to these proposals by curtailing or
deferring investments, including those for QuadraMed's products and services.
 
HIGHLY COMPETITIVE MARKET
 
     Competition in the market for QuadraMed's products and services (including
products and services acquired from Medicus and RHP by QuadraMed) is intense and
is expected to increase. Increased competition could result in price reductions,
reduced gross margins and loss of market share, any of which could materially
adversely affect QuadraMed's business, financial condition and results of
operations. While no one firm competes directly in all niches in which Medicus
and Rothenberg offers products, Medicus and Rothenberg each compete with several
firms of varying size and geographic coverage in each of their market niches.
QuadraMed's competitors include other providers of health care information
software and services, as well as health care consulting firms. The combined
company's principal competitors include: (i) CIS Technologies, Inc., a division
of National Data Corporation, Inc., and Sophisticated Software, Inc. in the
market for its EDI products; (ii) Envoy Corp. and MedE AMERICA in the market for
its claims processing service; (iii) Healthcare Cost Consultants, Inc., a
division of CIS Technologies, Inc., and Trego Systems, Inc. in the market for
its contract management products; (iv) IMNET Systems, Inc., Optika Imaging
Systems, Inc. and LanVision Systems, Inc. in the market for its electronic
document management products; (v) Transition Systems, Inc. and Healthcare
Microsystems, Inc., a division of Health Management Systems Inc., HCIA Inc. and
MediQual Systems, Inc., a division of Cardinal Health, Inc., in the market for
its decision support products; (vi) HMS and ARTRAC, a division of Medaphis Corp.
in the market for its business office outsourcing services; and (vii) a
subsidiary of Minnesota Mining and Manufacturing and CodeMaster in the market
for its medical records products. In addition, current and prospective customers
evaluate QuadraMed's capabilities against the merits of their existing
information systems and expertise. Furthermore, major software information
systems companies, including those specializing in the health care industry, not
presently offering products that compete with those offered by QuadraMed may
enter QuadraMed's markets. In addition, many of QuadraMed's competitors and
potential competitors have significantly greater financial, technical, product
development, marketing and other resources and market recognition than
QuadraMed. Many of QuadraMed's competitors also currently have, or may develop
or acquire, substantial installed customer bases in the health care industry. As
a result of these factors, QuadraMed's competitors may be able to respond more
quickly to new or emerging technologies and changes in customer requirements or
to devote greater resources to the development, promotion and sale of their
products than QuadraMed. There can be no assurance that QuadraMed will be able
to compete successfully against current and future competitors or that
competitive pressures faced by QuadraMed will not materially adversely affect
its business, financial condition and results of operations.
 
NEW PRODUCT DEVELOPMENT AND SYSTEM ENHANCEMENT
 
     QuadraMed's performance will depend in large part upon QuadraMed's ability
to provide the increasing functionality required by its customers through the
timely development and successful introduction of new products and enhancements
to its existing suite of products. QuadraMed has historically devoted
significant resources to product enhancements and research and development and
believes that significant continuing development efforts will be required to
sustain its operations and integrate the products and technologies of acquired
businesses. There can be no assurance that QuadraMed will successfully or in a
timely manner develop, acquire, integrate, introduce and market new product
enhancements or products, or that product enhancements or new products developed
by QuadraMed will meet the requirements of hospitals or other health care
providers and payors and achieve or sustain market acceptance.
 
                                       19
<PAGE>   34
 
LIMITED PROPRIETARY RIGHTS; RISK OF INFRINGEMENT
 
     QuadraMed relies on a combination of trade secrets, copyright and trademark
laws, nondisclosure and other contractual provisions to protect its proprietary
rights. QuadraMed has not filed any patent applications covering its technology.
There can be no assurance that measures taken by QuadraMed to protect its
intellectual property will be adequate or that QuadraMed's competitors will not
independently develop products and services that are substantially equivalent or
superior to those of QuadraMed.
 
     Substantial litigation regarding intellectual property rights exists in the
software industry, and QuadraMed expects that software products may be
increasingly subject to third-party infringement claims as the number of
competitors in QuadraMed's industry segment grows and the functionality of
products overlaps. Although QuadraMed believes that its products do not infringe
upon the proprietary rights of third parties, there can be no assurance that
third parties will not assert infringement claims against QuadraMed in the
future or that a license or similar agreement will be available on reasonable
terms in the event of an unfavorable ruling on any such claim. In addition, any
claim may require QuadraMed to incur substantial litigation expenses or subject
QuadraMed to significant liabilities and could have a material adverse effect on
QuadraMed's business, financial condition and results of operations. QuadraMed
has recently received notice of a claim filed with the United States Trademark
Appeal Board for the cancellation of its registered QuanTIM(R) trademark, and
also has recently received a letter from a separate third party challenging this
trademark. There can be no assurance that QuadraMed will be successful in its
defense of these or similar claims.
 
RISK OF PRODUCT DEFECTS; FAILURE TO MEET PERFORMANCE CRITERIA
 
     Products such as those offered by the combined company frequently contain
errors or failures, especially when initially introduced or when new versions
are released. Although each company conducts extensive testing, software errors
have been discovered in certain enhancements and products after their
introduction. QuadraMed and Medicus are currently developing various new
applications and each has recently introduced versions of certain of its
existing applications designed to function with the Microsoft Windows(TM) NT
operating system. There can be no assurance that, despite testing by QuadraMed
and by current and potential customers, errors or performance failures will not
occur in these products under development or in other enhancements or products
after commencement of commercial shipments, resulting in loss of revenues and
customers, delay in market acceptance, diversion of development resources,
damage to QuadraMed's reputation or increased service and warranty costs, any of
which could have a material adverse effect upon its business, financial
condition and results of operations.
 
RISK OF INTERRUPTION OF DATA PROCESSING
 
     QuadraMed currently processes substantially all its customer data at its
facilities in Larkspur, California and Neptune, New Jersey. While QuadraMed has
safeguards for emergencies such as power interruption or breakdown in
temperature controls, it has no mirror processing site to which processing could
be transferred in the case of a catastrophic event at either of these
facilities. The occurrence of a major catastrophic event at either the Larkspur
or the Neptune facility could lead to an interruption of data processing and
could have a material adverse effect on QuadraMed's business, financial
condition and results of operations.
 
RISKS RELATED TO OUTSOURCING BUSINESS
 
     QuadraMed provides business office outsourcing and cash flow management
services, including the billing and collection of receivables. The
infrastructure for QuadraMed's outsourcing business was acquired by QuadraMed.
In addition, QuadraMed often uses its software products to provide outsourcing
services. As a result, QuadraMed has not been required to make significant
capital expenditures in order to service existing outsourcing contracts.
However, if QuadraMed experiences a period of substantial expansion in its
outsourcing business, it may be required to make substantial investments in
capital assets and personnel, and there can be no assurance that it will be able
to assess accurately the investment required and negotiate and perform in a
profitable manner any of the outsourcing contracts it may be awarded.
QuadraMed's failure to estimate
 
                                       20
<PAGE>   35
 
accurately the resources and related expenses required for a project or its
failure to complete its contractual obligations in a manner consistent with the
project plan upon which a contract was based could have a material adverse
effect on its business, financial condition and results of operations. In
addition, QuadraMed's failure to meet a client's expectations in the performance
of its services could damage QuadraMed's reputation and adversely affect its
ability to attract new business. Finally, QuadraMed could incur substantial
costs and expend significant resources correcting errors in its work, and could
possibly become liable for damages caused by these errors.
 
GOVERNMENT REGULATION
 
     The United States Food and Drug Administration (the "FDA") is responsible
for assuring the safety and effectiveness of medical devices under the Federal
Food, Drug and Cosmetic Act. Computer products are subject to regulation when
they are used or are intended to be used in the diagnosis of disease or other
conditions, or in the cure, mitigation, treatment or prevention of disease, or
are intended to affect the structure or function of the body. The FDA could
determine in the future that any predictive aspects of QuadraMed's products make
them clinical decision tools subject to FDA regulation. Compliance with these
regulations could be burdensome, time consuming and expensive. QuadraMed also
could become subject to future legislation and regulations concerning the
development and marketing of health care software systems. Such legislation
could increase the cost and time necessary to market new products and could
affect QuadraMed in other respects not presently foreseeable. QuadraMed cannot
predict the effect of possible future legislation and regulation.
 
     The confidentiality of patient records and the circumstances under which
such records may be released for inclusion in QuadraMed's databases are subject
to substantial regulation by state governments. These state laws and regulations
govern both the disclosure and the use of confidential patient medical record
information. Although compliance with these laws and regulations is at present
principally the responsibility of the hospital, physician or other health care
provider, regulations governing patient confidentiality rights are evolving
rapidly. Additional legislation governing the dissemination of medical record
information has been proposed at both the state and federal levels. This
legislation may require holders of such information to implement security
measures that may require substantial expenditures by QuadraMed. There can be no
assurance that changes to state or federal laws will not materially restrict the
ability of health care providers to submit information from patient records
using QuadraMed's products.
 
UNCERTAINTY IN THE HEALTH CARE INDUSTRY
 
     The health care industry is subject to changing political, economic and
regulatory influences that may affect the procurement practices and operation of
health care organizations. Changes in current health care financing and
reimbursement systems could result in the need for unplanned product
enhancements, in delays or cancellations of product orders or shipments or in
the revocation of endorsement of QuadraMed's products by hospital associations
or other customers. Any of these occurrences could have a material adverse
effect on QuadraMed's business, financial condition and results of operations.
In addition, many health care providers are consolidating to create integrated
health care delivery systems with greater regional market power. As a result,
these emerging systems could have greater bargaining power, which may lead to
price erosion of QuadraMed's products. The failure of QuadraMed to maintain
adequate price levels would have a material adverse effect on QuadraMed's
business, financial condition and results of operations. Other market-driven
reforms could also have unpredictable effects on QuadraMed's business, financial
condition and results of operations.
 
RISK OF PRODUCT-RELATED CLAIMS
 
     Certain of the combined company's products and services relate to the
payment, collection, coding and billing of health care claims and the
administration of managed care contracts. Any failure by employees of QuadraMed
or by QuadraMed's products to accurately assess, process or collect such claims
could result in claims against QuadraMed by its customers. QuadraMed has been
and currently is involved in claims or administrates such contracts for money
damages related to services provided by its accounts receivable
 
                                       21
<PAGE>   36
 
management business. QuadraMed maintains insurance to protect against certain
claims associated with the use of its products, but there can be no assurance
that its insurance coverage would adequately cover any claim asserted against
QuadraMed. A successful claim brought against QuadraMed that is in excess of, or
excluded from, its insurance coverage could have a material adverse effect on
its business, financial condition and results of operations. Even unsuccessful
claims could result in QuadraMed's expenditure of funds in litigation and
management time and resources. There can be no assurance that QuadraMed will not
be subject to material claims in the future, that such claims will not result in
liability in excess of its insurance coverage, that QuadraMed's insurance will
cover such claims or that appropriate insurance will continue to be available to
QuadraMed in the future at commercially reasonable rates. In addition, if
liability of QuadraMed were to be established, substantial revisions to its
products could be required that may cause it to incur additional unanticipated
research and development expenses.
 
RISKS ASSOCIATED WITH CERTAIN INVESTMENTS
 
     QuadraMed has made, and may continue to make in the future, certain
investments in which it obtains a minority equity interest in certain early
stage companies. QuadraMed does not have the ability to control the operations
of any of these companies. Investing in early stage companies is subject to
certain significant risks, and there can be no assurance that any of these
companies will be successful or achieve profitability or that QuadraMed will
ever realize a return on its investments. To the extent any of these companies
are unprofitable, QuadraMed may be required to recognize a loss on its
investment during a reporting period. Any loss in connection with these
investments could have a material adverse effect on QuadraMed's business,
financial condition or results of operations during a particular reporting
period. In addition, to the extent any of such companies fail or become bankrupt
or insolvent, QuadraMed may be required to record a total loss on its
investment, which could have a material adverse effect on its results of
operations during a particular reporting period.
 
POTENTIAL EFFECT OF ANTI-TAKEOVER PROVISIONS
 
     Certain provisions of Delaware law applicable to QuadraMed could have the
effect of delaying, deterring or preventing a change in control of QuadraMed,
including Section 203 of the Delaware General Corporation Law, which prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years from the date the person
became an interested stockholder unless certain conditions are met. In addition,
QuadraMed's Certificate of Incorporation and Bylaws contain certain provisions
that could discourage potential takeover attempts and make attempts by
stockholders to change management more difficult. QuadraMed's Board of Directors
is classified into three classes of directors serving staggered, three-year
terms and has the authority without action by QuadraMed's stockholders to fix
the rights and preferences and issue shares of preferred stock, and to impose
various procedural and other requirements that could make it more difficult for
stockholders to effect certain corporate actions. QuadraMed's Certificate of
Incorporation provides that directors may be removed only by the affirmative
vote of the holders of two-thirds of the shares of capital stock of the
corporation entitled to vote. Any vacancy on the Board of Directors may be
filled only by vote of the majority of directors then in office. Further,
QuadraMed's Certificate of Incorporation provides that any "Business
Combination" (as therein defined) requires the affirmative vote of two-thirds of
the shares entitled to vote, voting together as a single class. These
provisions, and certain other provisions of the Certificate of Incorporation
which may have the effect of delaying proposed stockholder actions until the
next annual meeting of stockholders, could have the effect of delaying or
preventing a tender offer for QuadraMed's Common Stock or other changes of
control or management of QuadraMed, which could adversely affect the market
price of the QuadraMed Common Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE VOLATILITY OF STOCK PRICE; LOW TRADING
VOLUME
 
     After the Merger and assuming the issuance of 1,800,000 shares of QuadraMed
Common Stock pursuant to the Merger Agreement and the Warrants, approximately
[          ] shares of QuadraMed Common Stock issued to holders of Medicus
Common Stock and the Warrants will be freely tradeable, and an additional
[          ] shares of QuadraMed Common Stock will be tradeable under Rule 145
under the Securities Act. Additionally,
 
                                       22
<PAGE>   37
 
QuadraMed has issued 1,588,701 shares of QuadraMed Common Stock in connection
with the RHP Mergers, all of which are being registered under the Securities Act
on a Form S-3 filed concurrently with the registration statement on Form S-4
filed in connection with this Proxy Statement/Prospectus. As a result,
substantial sales of QuadraMed Common Stock could occur immediately after the
Merger. Sales of a substantial number of the aforementioned shares of QuadraMed
Common Stock could adversely affect or cause substantial fluctuations in the
market price of QuadraMed Common Stock and impair QuadraMed's ability to raise
additional capital through the sale of its equity securities.
 
     The stock market historically has experienced volatility which has affected
the market price of securities of many companies and which has sometimes been
unrelated to the operating performance of such companies. The trading price of
QuadraMed's Common Stock could also be subject to significant fluctuations in
response to variations in quarterly results of operations, announcements of new
products or acquisitions by QuadraMed or its competitors, governmental
regulatory action, other developments or disputes with respect to proprietary
rights, general trends in the industry and overall market conditions, and other
factors. The market price may also be affected by movements in prices of equity
securities in general. In addition, the average daily trading volume of
QuadraMed's Common Stock since public trading of the Common Stock commenced has
been low. To the extent this trading pattern continues, the price of the Common
Stock may fluctuate significantly as a result of relatively minor changes in
demand for such shares and sales of stock by stockholders.
 
RISKS RELATED TO MEDICUS LITIGATION
 
     On July 11, 1997, St. Joseph Hospital filed a lawsuit, St. Joseph Hospital
v. Medicus Systems Corporation, File No. 97-36574, in the District Court of
Harris County, Texas. The complaint alleges primarily breach of a contract to
provide case management software, and seeks unspecified damages, including
attorney's fees. Medicus vigorously denies any liability, and has filed an
answer denying the plaintiff's claims. In addition, Medicus has filed
counterclaims asserting breach of contract and fraudulent inducement. Medicus
believes that it has meritorious defenses to the plaintiff's claims, and it
intends to defend the litigation vigorously. However, due to the nature of the
litigation, the combined company cannot determine the total expense or possible
loss, if any, that may ultimately be incurred either in the context of a trial,
or as a result of a negotiated settlement. Regardless of the ultimate outcome
of the litigation, it could result in significant diversion of time by the
combined company's personnel. While management believes that the resolution of
these matters will not have a material adverse effect on the combined company's
business, financial condition and results of operation, the results of these
proceedings, including any potential settlement are uncertain and there can be
no assurance to that effect.

                                SPECIAL FACTORS
 
BACKGROUND OF THE MERGER
 
     From time to time, QuadraMed has evaluated strategic alliances, including
business combinations with other companies that could complement and strengthen
QuadraMed's product offerings and revenues. Similarly, from time to time,
Medicus has considered various opportunities for expanding its base of products
and distribution. QuadraMed and Medicus believe that the product lines of the
two companies are complementary, and that the Merger will strengthen the
resources, product offerings and distribution channels for each company.
 
     During 1996, management of Medicus, and in particular, Richard C. Jelinek,
who served as Chairman of the Board of Medicus and had voting control of Medicus
until March 19, 1997, explored the possibility of some form of business
combination with another company. Mr. Jelinek had, for some time, expressed his
concern that Medicus was too small to take advantage of the marketplace. He
believed that not only did Medicus lack the profitability and positive cash flow
to finance appropriate research and development, but also that the stand-alone
products being developed by Medicus would be best developed, marketed and sold
as part of a family of similar related products. Management had serious
discussions with two companies expressing preliminary interests in acquiring
Medicus during this period, but by October, 1996, both companies had informed
Medicus that they were not interested in pursuing discussions at that time.
 
     Mr. Jelinek continued to be interested in selling Medicus or his shares of
Medicus. Other Medicus directors did not believe that continuing discussions
with potential buyers at that time were in the best interest of Medicus. These
directors believed that Medicus would benefit from a period of uninterrupted
focus on its operations. In December 1996, representatives of Medicus reached an
agreement in principle with Mr. Jelinek whereby Medicus would acquire 1,000,000
shares of Medicus Common Stock and all of the controlling Medicus Voting
Preferred Stock from Mr. Jelinek. This transaction was completed on March 19,
1997.
 
     Following the March 19, 1997 repurchase of part of Mr. Jelinek's common
stock and all of his controlling Voting Preferred Stock, Medicus' financial
performance failed to meet the expectations of management or the Medicus Board.
Cash flow was less than anticipated and projected future research and
development costs exceeded previously projected levels. As a result, at a
meeting on July 10-11th, 1997, the Medicus Board expressed the view for the
first time that Mr. Jelinek's analysis might be correct and directed management,
among other things, to initiate discussions with selected investment bankers,
potential strategic partners and venture capital firms, concerning a possible
investment, refinancing or business combination involving Medicus.
 
     Following this July Board meeting, Patrick Sommers, Chief Executive Officer
of Medicus, and Dan DiCaro, Chief Financial Officer of Medicus, held discussions
with representatives of several investment banks, venture capital firms, and
companies in the health care software business. None of these discussions other
than the discussions with representatives of QuadraMed described below appeared
likely to result in a transaction that would be favorable to Medicus or its
stockholders.
 
     On August 12, 1997, Mr. Sommers and Lon Gruen, Senior Vice President,
Marketing, of Medicus, met with James D. Durham, Chairman and Chief Executive
Officer of QuadraMed, at QuadraMed's offices in Larkspur, California, presented
the Medicus business plan and discussed a possible acquisition of Medicus by
QuadraMed. QuadraMed expressed interest in receiving more information concerning
Medicus.
 
     On September 2, 1997 Mr. Sommers, Mr. Gruen and Mr. DiCaro met with Mr.
Durham and other members of QuadraMed management, as well as representatives of
Jefferies & Co., in Larkspur, and discussed the Medicus business model.
QuadraMed and Medicus signed a confidentiality agreement at this meeting.
 
     Mr. Sommers received a call on October 1, 1997 from Mr. Durham, during
which Mr. Durham indicated that QuadraMed continued to be interested in learning
more about Medicus but that QuadraMed was in the process of a public offering
and any further discussions could not take place until that offering was
completed.
 
                                       24
<PAGE>   39
 
     At a Medicus Board meeting on October 1 and October 2, Mr. Sommers
described his discussions to date with QuadraMed. The Board directed Mr. Sommers
to continue with such discussions.
 
     On October 23, 1997, Medicus received a letter from QuadraMed formally
proposing a merger transaction for a cash consideration of $6.00 per share,
subject to certain approvals and contingencies including negotiation of a
definitive acquisition agreement. On October 28, 1997, the Medicus Board met via
teleconference to discuss the proposal. Neither Mr. Sommers nor Mr. Jelinek
participated in this meeting. The Medicus Board felt that the purchase price
reflected in the offer was too low. However, the Medicus Board established a
special committee consisting of Dorsey Gardner, chair; Jon Jacoby and Patrick
Sommers (the "Special Committee") to negotiate with QuadraMed and attempt to
obtain a higher price.
 
     The Special Committee met after the Board meeting on October 28, and Mr.
Sommers was directed to prepare a proposal to present to QuadraMed justifying a
higher price. The Special Committee met again on October 30 to review this
proposal.
 
     Later on October 30, 1997, Mr. Sommers and Mr. DiCaro met with Mr. Durham
and John Cracchiolo, Chief Financial Officer of QuadraMed, at the Medicus
offices in Evanston, Illinois, gave further detailed information about Medicus
to the QuadraMed representatives, and discussed the QuadraMed offer. During
these discussions, Mr. Sommers and Mr. DiCaro explained why they believed
Medicus was worth more than $6.00 per share to QuadraMed. They also suggested
that Medicus stockholders would benefit by being offered the option of receiving
either cash or QuadraMed stock. At the conclusion of the meeting QuadraMed
representatives verbally raised QuadraMed's offer to $7.00 per share payable in
either cash, shares of QuadraMed Common Stock or a combination thereof, subject
to certain approvals and contingencies including negotiation of a definitive
acquisition agreement.
 
     The Special Committee, with William Brown (a director and Secretary of
Medicus) participating, met by teleconference on November 2, 1997 and determined
that, while the Special Committee would not make a recommendation, QuadraMed's
latest offer should be presented to the entire Medicus Board. The Medicus Board
met on November 3, 1997 via teleconference to discuss the revised proposal and
instructed Mr. Sommers to continue to negotiate to obtain a higher price.
 
     Mr. Sommers met with Mr. Durham and Mr. Cracchiolo in QuadraMed's offices
on November 4, 1997 and discussed the offer and the need for a higher purchase
price to secure unanimous approval of the Medicus Board. At this meeting,
subject to further consultation with directors, QuadraMed tentatively agreed to
raise the purchase price to $7.50 per share payable in either cash, shares of
QuadraMed Common Stock or a combination thereof. On November 5, 1997 Medicus
received a formal offer from QuadraMed at a purchase price of $7.50 per share,
payable in cash, QuadraMed Common Stock or a combination thereof, subject to
certain approvals and contingencies including negotiation of a definitive
acquisition agreement.
 
     On November 6, 1997 the Medicus Board met via teleconference to discuss the
revised proposal. The Board unanimously approved the basic terms of the offer,
subject to negotiation of an acceptable definitive agreement, and instructed Mr.
Sommers to enter into such negotiations.
 
     Mr. Sommers and Medicus management and their representatives met with
members of QuadraMed management and their representatives in Evanston beginning
November 7, and from November 7 through November 9, such representatives
negotiated and drafted the definitive Merger Agreement.
 
     At a meeting of the QuadraMed Board held by teleconference on November 9,
the QuadraMed Board unanimously approved the Stock Purchase Agreements, the
Warrants, the Merger and the Merger Agreement. One director of QuadraMed, Mr.
Kenneth E. Jones, did not participate in the November 9 meeting. Mr. Thomas F.
McNulty, a director of QuadraMed, abstained from voting because he holds options
to purchase Medicus Common Stock.
 
     At a meeting of the entire Medicus Board held by teleconference on November
9, the Medicus Board unanimously approved the Merger and the Merger Agreement.
 
     The companies executed the Merger Agreement on Sunday afternoon, November
9, 1997, and the agreement to merge was publicly announced early Monday morning,
November 10, 1997 by the issuance of a
 
                                       25
<PAGE>   40
 
joint press release. QuadraMed also executed the Stock Purchase Agreements with
certain stockholders of Medicus on November 9, 1997 and completed the purchase
of 56.7% of the outstanding shares of Medicus Common Stock during the week of
November 10, 1997.
 
PURPOSE AND STRUCTURE OF THE MERGER
 
     The purpose of the Merger is for QuadraMed to acquire the entire equity
interest in Medicus. Because holders of Medicus Common Stock have the right to
elect to receive QuadraMed Common Stock, they will have the opportunity to
maintain an indirect equity interest in Medicus through an Election Procedure.
 
SOURCE AND AMOUNT OF FUNDS
 
     If all Medicus stockholders elect to receive cash in the Merger and
assuming no current Medicus option holders exercise options to purchase Medicus
Common Stock, approximately $18.1 million will be required to pay such
consideration. In addition, QuadraMed will pay fees and expenses of
approximately $          in connection with the Merger. The cash required in
connection with the Merger will be provided by current cash resources of
QuadraMed.
 
     In connection with its purchase of 56.7% of the outstanding shares of the
Medicus Common Stock, QuadraMed paid cash to the Selling Stockholders of
approximately $23.3 million, which amount was funded by QuadraMed's existing
cash resources.
 
CERTAIN EFFECTS OF THE MERGER; PLANS FOR THE COMPANY AFTER THE MERGER
 
     Following the Merger, QuadraMed will own 100% of the outstanding capital
stock of the Surviving Corporation (as defined in "THE MERGER AGREEMENT -- The
Merger"). As such, QuadraMed will be the direct beneficiary of any future
earnings and growth of the Surviving Corporation, and will have the ability to
benefit from any divestitures, strategic acquisitions or other corporate
opportunities that may be pursued by the Surviving Corporation in the future.
Upon the consummation of the Merger, each share of Medicus Common Stock issued
and outstanding immediately prior to the Effective Time (other than any shares
of Medicus Common Stock owned by Medicus or QuadraMed) will be cancelled and
extinguished and be converted into the right to receive the Merger Consideration
and the stockholders of Medicus will cease to have any direct ownership interest
in Medicus.
 
     As a result of the Merger, the Surviving Corporation will be privately held
and there will be no market for the Medicus Common Stock. Upon consummation of
the Merger, the Medicus Common Stock will cease to be listed on the Nasdaq
National Market and the registration of the Medicus Common Stock under the
Exchange Act will be terminated. Accordingly, Medicus will no longer be required
to file periodic reports with the Commission.
 
     It is expected that following the Merger, the business and operations of
Medicus will be continued under the QuadraMed name, substantially as they are
being conducted presently. However, QuadraMed and management of Medicus will
continue to evaluate Medicus' business and operations after the consummation of
the Merger and make such changes as are deemed appropriate. Specifically,
employees in Medicus' decision support operations will report to the manager of
QuadraMed's value added services division, and employees in QuadraMed's
existing medical records product lines will report to the manager of the
Medicus medical records division. Except as otherwise indicated in this Proxy
Statement/ Prospectus, QuadraMed does not have any plans or proposals
subsequent to the Merger that relate to or would result in any extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving Medicus, or a sale or transfer of a material amount of the assets of
Medicus. QuadraMed has begun combining certain redundant operations of Medicus
and eliminating certain corporate operations previously conducted at Medicus,   
including certain human resource and finance functions.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF MEDICUS; REASONS FOR THE MERGER
 
     At its November 9, 1997 meeting, the Medicus Board of Directors unanimously
determined that the Merger, upon the terms and conditions set forth in the
Merger Agreement, is fair to, and in the best interests
 
                                       26
<PAGE>   41
 
of, the holders of Medicus Common Stock. Accordingly, the Medicus Board of
Directors has unanimously adopted the Merger Agreement and unanimously
recommends that Medicus stockholders vote for approval and adoption of the
Merger Agreement and the transactions contemplated thereby, including the
Merger, at the Special Meeting. See "-- Background of the Merger." In reaching
this determination, the Medicus Board of Directors considered a number of
factors, including those set forth below.
 
     At the time the Medicus Board approved the Merger Agreement, the members
unanimously believed that not only did Medicus lack the profitability and
positive cash flow to finance appropriate research and development, but also
that the stand-alone products being developed by Medicus would be best
developed, marketed and sold as part of a family of similar related products.
Based on management's discussions with investment banks, venture capital firms
and other companies described above, which discussions continued during the
period of the negotiations with QuadraMed, the QuadraMed proposal represented
both the most concrete and most favorable opportunity for Medicus and its
stockholders.
 
     The Medicus Board believes that the $7.50 consideration to be received in
the Merger represents a fair price to stockholders in light of both recent and
historical market prices of Medicus Common Stock and the future prospects for
Medicus' business. The Medicus Board also believes that the ability to continue
to participate in the growth of the Medicus business through the ownership of
QuadraMed Common Stock by those stockholders who elect to receive QuadraMed
Common Stock represents a favorable opportunity for such stockholders. In
addition, the Medicus Board believes that the Merger represents an excellent
opportunity to grow and improve the business of Medicus. While certain
administrative savings will result from the combination of the two companies,
their businesses also complement each other very well. In particular, the
combination of the decision support business of the two companies will enable
them to offer a more complete solution to customers; in addition, QuadraMed's
DRG Check product provides increased functionality for Medicus' Clinical Data
Systems customers. Finally, QuadraMed possesses the capital resources necessary
to effectively operate and expand Medicus' businesses. These resources, together
with the synergies and savings referred to above, led the Medicus Board to
conclude that QuadraMed's proposal was an attractive opportunity to improve
Medicus' business. The amount and form of the Merger Consideration are, in the
Medicus Board's opinion, fair and in the best interests of Medicus'
stockholders.
 
     In reaching its determination, the Medicus Board consulted with management,
as well as its legal counsel, and considered a number of factors, including the
following material factors, both positive and negative:
 
          (i) the Board's knowledge of the business, operations, properties,
     assets, financial condition and operating results of Medicus;
 
          (ii) the Board's knowledge of, and confidence in, James D. Durham,
     QuadraMed's Chief Executive Officer, resulting from certain Board members'
     shared experiences with him as co-employees, co-directors and co-investors
     in several predecessor corporations of Medicus, Knowledge Data Systems
     Corporation and several other companies with which Mr. Durham was involved
     prior to his founding QuadraMed, and his performance as founder and chief
     executive officer of QuadraMed;
 
          (iii) the reports and opinions of Medicus' management, its legal
     counsel and its independent auditors, including the result of their due
     diligence investigations concerning the business, operations and financial
     condition of QuadraMed;
 
          (iv) the effect on stockholder value of Medicus continuing as an
     independent entity compared to the effect of a combination with QuadraMed,
     in light of the financial condition and prospects of Medicus and the
     current economic and industry environment, including, but not limited to,
     (A) other possible strategic alternatives for Medicus which the Medicus
     Board of Directors had examined, including continuing to execute its
     business plan on a stand-alone basis, and (B) the potential for increased
     value in the combined QuadraMed/Medicus enterprise;
 
          (v) recent and current market prices of the QuadraMed Common Stock;
 
                                       27
<PAGE>   42
 
          (vi) the terms and conditions of the Merger Agreement and the related
     documents, which were the product of extensive arms-length negotiations;
 
          (vii) the premium represented by the Exchange Ratio of (a)
     approximately 36% over the Medicus Common Stock closing sales price on
     November 7, 1997, the last trading day prior to the meeting of the Medicus
     Board of Directors at which the Merger Agreement was approved, (b)
     approximately 37% over the price one week before November 7, 1997, and (c)
     approximately 13% over the price four weeks before November 7, 1997;
 
          (viii) the compatibility of the respective business philosophies of
     QuadraMed and Medicus;
 
          (ix) the opportunity for Medicus stockholders to participate, as
     holders of QuadraMed Common Stock, in a larger, more diversified company;
 
          (x) the risk that Medicus will not achieve the synergies and cost
     savings anticipated to be achieved in the Merger, including a reduction in
     expenses resulting from the combined purchasing power of the two companies;
 
          (xi) the risk that the operations of the two companies would not be
     successfully integrated;
 
          (xii) the risk that key technical and management personnel might be
     lost prior to or after consummation of the Merger and the potential to
     mitigate this risk by negotiating the conversion of Medicus options into
     QuadraMed options;
 
          (xiii) Medicus' future prospects for executing its business strategy
     and the likelihood that such prospects would be enhanced upon consummation
     of the Merger in light of the enhanced competition from software suppliers
     to the health care industry;
 
          (xiv) the adverse effects on Medicus' business, operations and
     financial condition should it not be possible to consummate the Merger
     following public announcement that the Merger Agreement had been entered
     into; and
 
          (xv) other risks associated with QuadraMed and Medicus' businesses,
     including those described above under "RISK FACTORS."
 
     The foregoing discussion of the information and factors considered by the
Medicus Board of Directors is not intended to be exhaustive but includes all
material factors considered by the Medicus Board of Directors. In view of the
variety of factors considered in connection with its evaluation of the Merger,
the Medicus Board of Directors did not find it practicable to and did not
quantify or otherwise assign relative weights to the specific factors considered
in reaching its determination. In addition, individual members of the Medicus
Board of Directors may have given different weights to different factors. In the
course of its deliberations, the Medicus Board of Directors did not establish a
range of value for Medicus; however, based on the factors outlined above, the
Medicus Board of Directors determined that the Merger is advisable and fair and
in the best interests of Medicus and its stockholders.
 
     THE MEDICUS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF
MEDICUS COMMON STOCK VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
OPINION OF MEDICUS' FINANCIAL ADVISOR
 
     Medicus retained Volpe Brown Whelan & Company, LLC ("VBW&Co.") to render an
opinion to the Medicus Board of Directors as to the fairness, from a financial
point of view, to the stockholders of Medicus, other than QuadraMed, of the
consideration to be received by such stockholders in the Merger. On December 30,
1997, VBW&Co. rendered its opinion to Medicus' Board of Directors to the effect
that, as of such date and based on and subject to the matters stated in the
opinion, the Merger Consideration is fair, from a financial point of view, to
the stockholders of Medicus, other than QuadraMed.

     THE FULL TEXT OF VBW&CO.'s WRITTEN OPINION DATED DECEMBER 30, 1997 WHICH
SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED, AND LIMITATIONS ON THE
REVIEW UNDERTAKEN, IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX B AND
IS INCORPORATED HEREIN BY REFERENCE. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE FULL TEXT OF SUCH OPINION. HOLDERS OF MEDICUS COMMON STOCK
ARE URGED TO, AND SHOULD, READ THIS OPINION CAREFULLY IN ITS ENTIRETY. THE
ENGAGEMENT OF VBW&CO. AND ITS OPINION ARE FOR THE BENEFIT OF THE MEDICUS BOARD.
VBW&CO.'S OPINION ADDRESSES ONLY THE FAIRNESS OF THE MERGER CONSIDERATION FROM A
FINANCIAL POINT OF VIEW TO THE STOCKHOLDERS OF MEDICUS, OTHER THAN QUADRAMED,
AND IT DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER NOR DOES IT CONSTITUTE A
RECOMMENDATION TO ANY HOLDER OF MEDICUS COMMON STOCK AS TO HOW TO VOTE WITH
RESPECT TO THE MERGER.
 
     In arriving at its opinion, VBW&Co.: (i) reviewed the Merger Agreement;
(ii) discussed the proposed terms of QuadraMed's prospective acquisition of
Resource Health Partners, L.P. ("RHP") with QuadraMed management; (iii)
interviewed management of Medicus and QuadraMed concerning the business
prospects, financial outlook and operating plans of each company individually
and combined; (iv) reviewed certain historical Medicus and QuadraMed, and
certain projected Medicus and QuadraMed (including RHP) financial statements and
other relevant financial and operating data of Medicus and QuadraMed prepared by
the respective company management teams; (v) reviewed the historical stock
trading patterns of both QuadraMed and Medicus and analyzed implied historical
exchange ratios as well as the premium of the Merger Consideration in relation
to historical Medicus stock trading ranges; (vi) reviewed the valuation of
selected publicly-traded companies VBW&Co. deemed comparable and relevant to the
Merger; (vii) reviewed, to the extent publicly-available, the financial terms of
selected merger and acquisition transactions VBW&Co. deemed comparable and
relevant to the Merger; (viii) reviewed the relative contribution each of
Medicus and QuadraMed would make to the combined company in terms of financial
results and compared the implied values resulting from this analysis with the
Merger Consideration; (ix) performed a discounted cash flow analysis of Medicus
as a stand-alone entity based upon financial projections of Medicus management;
(x) performed a pro forma financial impact analysis of the combined entity,
based upon financial projections provided by Medicus and QuadraMed; and (xi)
performed other such studies, analyses and inquiries and considered other such
information as we deemed relevant.
 
     In rendering its opinion, VBW&Co. relied without independent verification
upon the accuracy and completeness of all of the financial, accounting, legal,
tax, operating and other information provided to VBW&Co. by Medicus and
QuadraMed and relied upon the assurances of Medicus and QuadraMed that all such
information provided by them, respectively, was complete and accurate in all
material respects and that there was no additional material information known to
any of them that would make any of the information made available to VBW&Co.
either incomplete or misleading. Medicus also retained outside legal, accounting
and tax advisors to advise on matters relating to the Merger. Accordingly,
VBW&Co. relied on their advice and expresses no opinion on such matters. With
respect to the projected financial data of Medicus and QuadraMed (including
RHP), all of which was provided by the management of Medicus or QuadraMed, as
well as the combined business plan, VBW&Co. has relied upon assurances of each
company that such data was prepared in good faith on a reasonable basis
reflecting the best currently available estimates and judgments of Medicus and
QuadraMed managements as to the future financial performance of each company
separately and as a combined company. VBW&Co. has not made any independent
appraisals or valuations of any assets of Medicus or QuadraMed, nor has VBW&Co.
been furnished with any such appraisals or valuations. In addition, VBW&Co.
assumed that the Merger would be accounted for as a purchase for financial
reporting purposes and the Merger Consideration would be taxable to Medicus
stockholders when received. VBW&Co.'s opinion is necessarily based on economic,
market and other conditions as in effect on, and the information made available
to VBW&Co. as of, the date it rendered its opinion.

     The following is a brief summary of the material analyses performed by
VBW&Co. in rendering its opinion to the Board of Directors of Medicus. The pro
forma financial impact analysis and contribution analysis include the expected
results of RHP, based on information provided by QuadraMed.
 
     Stock Trading and Exchange Ratio Analysis. VBW&Co. analyzed the stock
trading patterns of both Medicus and QuadraMed over various periods of time and
compared them historically to one another. From January 1, 1996 to November 7,
1997 (the last trading day prior to the announcement of the Merger), Medicus
stock ranged from $10.19 per share on February 16, 1996 (prior to the spin-off
on March 1, 1996 of Managed Care Solutions, Inc.) to $4.00 per share on August
7, 1997, August 8, 1997 and October 28, 1997 with a mean daily closing price of
$6.00 per share. The last time the stock price exceeded the level of Merger
Consideration was during the week of March 8, 1996. On a volume basis, 82.5% of
Medicus' trades from January 1, 1996 to November 7, 1997 were below $7.50 per
share and 99.8% of trades from January 1, 1997 to November 7, 1997 were below
$7.50 per share. The exchange ratio implied from dividing historical Medicus
stock prices by QuadraMed stock prices generally was in excess of the Exchange
Ratio prior to August 1, 1997 and was below the Exchange Ratio thereafter. The
implied exchange ratio ranged from 0.1984 - 0.8704 with a mean of 0.4868 since
QuadraMed's IPO. VBW&Co. noted that the implied exchange ratio was 0.2292 and
0.2659 one day and one month, respectively, prior to the date of announcement.
VBW&Co. placed greater weight on the more recent implied exchange ratios one day
and one month prior to the date of announcement.
 
     Premium Analysis. VBW&Co. analyzed the premiums paid in eight Healthcare
Information Services ("HCIS") transactions ("HCIS Premium Panel") deemed
comparable by VBW&Co. and in merger and acquisition transactions generally and
compared them to the premium represented by the Merger Consideration. The Merger
Consideration represents a premium of 36.4% and 30.4% compared to Medicus' stock
price one day and one month prior to the date of announcement, respectively.
 
     For the HCIS Premium Panel, one day premiums ranged from 5.5% to 53.3% with
a median of 17.1% and one month premiums ranged from 10.5% to 110.0% with a
median of 36.8%. These values would imply stock prices based on one day premiums
ranging from $5.80 to $8.43 with a median of $6.44 and stock prices based on one
month premiums ranging from $6.35 to $12.08 with a median of $7.87. For M&A
transactions announced from January 1, 1997 through December 5, 1997 involving
less than $200 million in consideration and with premiums ranging from 0.0% to
131.0%, one day premiums ranged from 0.5% to 108.7% with a median of 22.3% and
one month premiums ranged from 0.9% to 130.9% with a median of 31.2%. These
values would imply stock prices based on one day premiums ranging from $5.53 to
$11.48 with a median of $6.73 and stock prices based on one month premiums
ranging from $5.80 to $13.28 with a median of $7.54.
 
     Comparable Publicly-Traded Company Analysis. VBW&Co. compared certain
financial information of Medicus with that of two groups of publicly-traded
companies selected by VBW&Co. The first group (the "HCIS Panel") were selected
by VBW&Co. based on whether or not each company generated most of its revenues
and earnings from HCIS related businesses. A subset of the first group was also
selected by VBW&Co. composed of those companies that, in the view of VBW&Co.,
are most directly comparable to Medicus (the "Most Comparable Panel"). These
companies include APACHE Medical Systems, Inc., HCIA Inc., MECON, Inc.,
Medirisk, Inc., QuadraMed Corporation, Summit Medical Systems, Inc. and
Transition Systems, Inc. VBW&Co. selected these companies based on similarity of
product lines and on general similarity in size in terms of revenues and
earnings as compared to Medicus.
 
     The HCIS Panel financial information reviewed included stock price in
relation to forecasted calendar year ("FCY") 1998 earnings per share ("EPS") and
book value of stockholders' equity as well as enterprise value (defined as
market capitalization plus funded debt less cash) in relation to last 12 months
("L12M") revenue. FCY 1997 EPS and FCY 1998 EPS for the HCIS Panel were based on
published estimates by research organizations, including those of VBW&Co. Due to
Medicus' losses in the L12M period and FCY 1997, multiples of L12M EBITDA, EBIT,
and net income as well as FCY 1997 net income were not meaningful. VBW&Co. noted
that, based on closing stock prices and earnings estimates as of December 26,
1997, the HCIS Panel traded in a range of 10.7 to 48.3 times FCY 1998 earnings
(with a median of 25.8 times) and 0.4 to 11.3 times book value (with a median of
2.8 times). The enterprise value of the HCIS Panel implied from the stock prices
provided a range of 0.2 to 11.8 times L12M revenues (with a median of 2.5
 
                                       30

times). The implied range of stock prices for Medicus based on the HCIS Panel's
stock prices in relation to FCY 1998 EPS was $1.94 to $8.76 (with a median of
$4.67) and $0.74 to $18.58 (with a median of $4.56) in relation to book value.
The implied range of stock prices for Medicus based on the enterprise value of
the HCIS Panel implied from the stock prices was $0.21 to $39.73 (with a median
of $8.34) in relation to L12M revenues.
 
     The Most Comparable Panel financial information reviewed included stock
price in relation to FCY 1998 EPS and book value of stockholders' equity as well
as enterprise value in relation to L12M revenue. VBW&Co. noted that, based on
closing stock prices and earnings estimates as of December 26, 1997, the Most
Comparable Panel traded in a range of 14.4 to 34.6 times FCY 1998 earnings (with
a median of 28.0 times) and 0.4 to 5.7 times book value (with a median of 2.8
times). The enterprise value of the Most Comparable Panel implied from the stock
prices provided a range of 0.2 to 7.4 times L12M revenues (with a median of 2.3
times). The implied range of stock prices for Medicus based on the Most
Comparable Panel's stock prices in relation to FCY 1998 EPS was $2.60 to $6.28
(with a median of $5.08) and $0.74 to $9.33 (with a median of $4.54) in relation
to book value. The implied range of stock prices for Medicus based on the
enterprise value of the Most Comparable Panel implied from the stock prices was
$0.21 to $25.03 (with a median of $7.48) in relation to L12M revenues. VBW&Co.
placed more weight on valuation results based on FCY 1998 earnings than those
based on revenue and book value since it was the only available valuation
statistic based on profitability.
 
     Comparable Merger and Acquisition Transactions. VBW&Co. has prepared a
valuation of Medicus based upon 15 merger and acquisition transactions of target
companies participating in the HCIS industry ("HCIS Transaction Panel"). In
selecting the HCIS Transaction Panel, VBW&Co. considered whether or not the
target company generated most of its revenues and earnings from HCIS-related
businesses. VBW&Co. also prepared a valuation of Medicus based upon four merger
and acquisition transactions of target companies that, in the view of VBW&Co.,
are most directly comparable to Medicus ("Most Comparable HCIS Transaction
Panel"). The Most Comparable HCIS Transaction Panel includes HBO & Company's
acquisition of GMIS Inc., HBO & Company's acquisition of HPR Inc., Cardinal
Health, Inc.'s acquisition of MediQual Systems, Inc., and National Data
Corporation's pending acquisition of Source Informatics Inc. VBW&Co. selected
these companies based on the similarity of their product lines and on the
similarity in size in terms of revenues and earnings as compared to Medicus.
 
     VBW&Co. reviewed the HCIS Transaction Panel's financial terms, to the
extent publicly available. The enterprise value of these transactions ranged
from 2.0 to 10.6 times L12M revenue (with a median of 4.2 times) and 1.1 to 6.8
times next 12 months forecasted ("N12M") revenue (with a median of 3.0 times).
The transaction value of these transactions ranged from 2.5 to 9.5 times book
value (with a median of 5.2 times), and 11.0 to 41.5 times N12M net income (with
a median of 33.7 times). Due to Medicus' operating losses in L12M EBITDA, EBIT,
and net income, multiples of L12M EBITDA, EBIT, and net income were not
meaningful. The implied range of stock prices for Medicus based on HCIS
Transaction Panel's enterprise value in relation to L12M revenue was $6.52 to
$35.91 (with a median of $13.85) and $4.71 to $29.51 (with a median of $13.14)
in relation to N12M revenue. The implied range of stock prices for Medicus based
on HCIS Transaction Panel's transaction value in relation to book value was
$4.13 to $15.60 (with a median of $8.55) and $1.99 to $7.52 (with a median of
$6.11) in relation to N12M net income.
 
     VBW&Co. also reviewed the Most Comparable HCIS Transaction Panel's
financial terms, to the extent publicly available. The enterprise value of these
transactions ranged from 2.4 to 8.6 times L12M revenue (with a median of 6.0
times) and 1.1 to 6.8 times N12M revenue (with a median of 3.4 times). The
transaction value of these transactions ranged from 4.0 to 9.5 times book value
(with a median of 6.7 times), and 11.0 to 41.5 times N12M net income (with a
median of 34.1 times). The implied range of stock prices for Medicus based on
the Most Comparable HCIS Transaction Panel's enterprise value in relation to
L12M revenue was $8.03 to $29.16 (with a median of $20.30) and $4.71 to $29.51
(with a median of $14.86) in relation to N12M revenue. The implied range of
stock prices for Medicus based on the Most Comparable HCIS Transaction Panel's
transaction value in relation to book value was $6.54 to $15.60 (with a median
of $11.07) and $1.99 to $7.52 (with a median of $6.18) in relation to N12M net
income. VBW&Co. placed more weight on valuation
 
                                       31
<PAGE>   46
 
results based on N12M net income than those based on revenue and book value
since it was the only available valuation statistic based on profitability.
 
     Contribution Analysis. VBW&Co. reviewed certain historical and forecasted
financial information (including revenue, gross profit, EBITDA, EBIT, net income
and book value) for Medicus and QuadraMed (including RHP) and the pro forma
combined entity resulting from the Merger. VBW&Co. adjusted the relative
contributions of revenue, gross profit, EBITDA and EBIT to reflect the
differences in capital structures of the two companies. VBW&Co. analyzed the
relative contributions of Medicus and QuadraMed (including RHP) based on
historical financial performance for L12M and forecasted financial performance
for 1997 through 2000 provided by the management teams of Medicus and QuadraMed
(including RHP). Based on the foregoing analysis, VBW&Co. concluded that Medicus
would be contributing the following percentages of revenue (26.3% in L12M, 23.2%
in FCY 1997 and 21.0% in FCY 1998), gross profit (28.6% in L12M, 25.5% in FCY
1997 and 24.5% in FCY 1998), EBITDA (-0.7% in L12M, -0.7% in FCY 1997 and 13.5%
in FCY 1998), EBIT (-0.7% in L12M, -0.7% in FCY 1997 and 9.3% in FCY 1998), net
income (0% in L12M, 0% in FCY 1997 and 9.8% in FCY 1998) and book value (8.4% in
L12M, 8.3% in FCY 1997 and 8.4% in FCY 1998). VBW&Co. determined that the
preceding ratios implied the following stock prices for Medicus: L12M revenue:
$16.09; FCY 1997 revenue: $13.61; FCY 1998 revenue: $12.01; L12M gross profit:
$18.07; FCY 1997 gross profit: $15.46; FCY 1998 gross profit: $14.63; L12M
EBITDA: not meaningful; FCY 1997 EBITDA: not meaningful; FCY 1998 EBITDA: $7.02;
L12M EBIT: not meaningful; FCY 1997 EBIT: not meaningful; FCY 1998 EBIT: $4.63;
L12M net income: not meaningful; FCY 1997 net income: not meaningful; FCY 1998
net income: $4.88; L12M book value: $4.14; FCY 1997 book value: $4.07; FCY 1998
book value: $4.14.
 
     Discounted Cash Flow Analysis. VBW&Co. performed a discounted cash flow
analysis of Medicus based on certain financial projections provided by the
management team of Medicus for the periods 1997 through 2002. Unlevered free
cash flows were calculated as net income available to common stockholders plus
the sum of depreciation, amortization and other non-cash charges minus capital
expenditures and plus or minus changes in working capital and minus tax adjusted
interest expense. VBW&Co. calculated terminal values by applying exit multiples
on 2002 net income; and the cash flow streams and terminal values were then
discounted to the present using a range of discount rates deemed appropriate by
VBW&Co. Based on this analysis, VBW&Co. calculated stock prices of Medicus
ranging from $9.92 to $21.94.
 
     Pro Forma Financial Impact Analysis. VBW&Co. analyzed the pro forma impact
of the Merger on QuadraMed's earnings per share for the calendar years 1998
through 2002. The analysis was performed utilizing stand-alone operating
estimates and estimates of transaction-related costs and projected cost savings
resulting from the Merger provided by the management teams of QuadraMed and
Medicus. VBW&Co. expresses no opinion as to whether these projections and
estimates would actually be obtained. VBW&Co. noted that based on management
projections, the Merger would be accretive to QuadraMed's 1998 earnings and
significantly accretive to QuadraMed's 1999 and beyond earnings. The analysis
assumed that the RHP acquisition was completed prior to the Merger.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, VBW&Co. considered the results of all of its analyses
as a whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, selecting any portion of the analysis, without
considering all of the analyses, would create an incomplete view of the process
underlying its opinion. In addition, VBW&Co. may have given various analyses and
factors more or less weight than other analyses and factors, and may have deemed
various assumptions more or less probable than other assumptions, so that the
ranges of valuations resulting from any particular analysis described above
should not be taken to be VBW&Co.'s view of the actual value of Medicus.
 
     The analyses performed by VBW&Co. are not necessarily indicative of actual
value, which may be significantly more or less favorable than the value
suggested by such analyses. Such analyses were prepared solely as part of
VBW&Co.'s analysis of the fairness of the Merger Consideration from a financial
point of view to the stockholders of Medicus other than QuadraMed. The analyses
do not purport to be appraisals or to reflect the prices at which Medicus might
actually be sold. Because such estimates are inherently subject to
 
                                       32
<PAGE>   47
 
uncertainty, none of Medicus, QuadraMed, VBW&Co. nor any other person assumes
responsibility for their accuracy. Consequently, the VBW&Co. analyses described
herein should not be viewed as determinative of the opinion of the Medicus Board
of Directors with respect to the value of Medicus or of whether the QuadraMed
Board of Directors or the Medicus Board of Directors would have been willing to
agree to a different level of consideration.
 
     VBW&Co. is a nationally recognized investment banking firm and was selected
by Medicus based on VBW&Co.'s experience and expertise. VBW&Co., as a customary
part of its investment banking business, engages in the valuation of businesses
and their securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of securities, private placements and
valuations for corporate and other purposes. In the ordinary course of its
business, VBW&Co. and its affiliates may actively trade the equity securities of
QuadraMed or Medicus for its and their own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     VBW&Co. has been engaged by QuadraMed to provide investment banking and
financial advisory services to QuadraMed unrelated to the Medicus transaction.
To date no fees have been paid to VBW&Co. by QuadraMed. VBW&Co. has also been
retained by RHP to provide financial advice and a fairness opinion to RHP with
respect to the acquisition of RHP by QuadraMed and will receive a fee for
rendering such opinion to RHP.
 
     VBW&Co. will receive a fee for rendering its opinion to Medicus, no portion
of which is conditioned upon the opinion being favorable. In addition, Medicus
has agreed to reimburse VBW&Co. for its out-of-pocket costs and expenses and to
indemnify VBW&Co. and its affiliates against certain liabilities and expenses.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Board of Directors of Medicus with
respect to the Merger, holders of Medicus Common Stock should be aware that
certain members of Medicus' management, some of whom are members of the Medicus
Board of Directors, and the members of the Medicus Board of Directors have
certain interests in the Merger, in addition to those of Medicus' stockholders
generally. The Board of Directors of Medicus was aware of these interests when
it considered and approved the Merger and the Merger Agreement.
 
     Upon consummation of the Merger, QuadraMed has agreed to enter into an
employment agreement with Patrick C. Sommers, President and Chief Executive
Officer of Medicus. Pursuant to such employment agreement, Mr. Sommers was paid
a signing bonus of $75,000, a pro rata portion of which is subject to repayment
by Mr. Sommers in the event his employment with QuadraMed terminates (other than
without cause) prior to November 9, 1998. Additionally, the employment agreement
provides that Mr. Sommers be paid an annual salary of $175,000, subject to
upward adjustment after an annual review, and an annual bonus. In fiscal year
1998, Mr. Sommers will receive a bonus of no less than $75,000. In the event Mr.
Sommers is terminated by QuadraMed without cause, he will receive a lump sum
payment equal to 150% of his then current salary and benefits for 12 months and
his vested options will remain exercisable for a period of three years following
the date of his termination. In the event Mr. Sommers' termination without
cause results from a change in control of Quadramed, all of his unvested
options will automatically accelerate and become immediately exercisable and
will remain exercisable for a period of three years following such termination.
Mr. Sommers' employment agreement also contains a non-compete provision in which
Mr. Sommers agrees not to compete with QuadraMed in the United States for a
period of 18 months following termination of his employment with QuadraMed. In
addition, at the November 9, 1997 meeting at which the Merger was approved, the
Medicus Board also approved the payment to Mr. Sommers of a bonus in the amount
of $750,000 in satisfaction of Medicus' obligation under Mr. Sommers' employment
agreement to make certain payments in the event of a change in control of
Medicus. The immediate vesting of all stock options held by Mr. Sommers was
approved as well, with such options to be exercisable for a period of three
years after termination of Mr. Sommers' employment.
 
     Concurrent with the execution of the Merger Agreement, certain stockholders
of Medicus, including Richard C. Jelinek, William G. Brown, Jon E.M. Jacoby,
Gail L. Warden and Dorsey R. Gardner, each of whom are directors of Medicus,
sold their shares of Medicus Common Stock to QuadraMed pursuant to stock
purchase agreements dated November 9, 1997. The consideration paid by QuadraMed

shares of QuadraMed Common Stock for each share

of Medicus Common Stock sold at a price of $24.00 per share (the closing price
of the QuadraMed Common Stock on the last trading day prior to the execution of
the stock purchase agreements), subject to certain adjustments. The Warrants are
exercisable only at the Effective Time of the Merger. See "THE STOCK PURCHASE
AGREEMENTS AND WARRANTS."
 
     Pursuant to the Merger Agreement, the obligations under the Medicus Stock
Option Plans and the TriHealth Warrant will be assumed by QuadraMed. Each option

so assumed by QuadraMed shall continue to have, and be subject to, the same
terms and conditions set forth in the Medicus Stock Option Plans and the
TriHealth Warrant shall continue to have, and be subject to, the same terms and
conditions set forth therein, immediately prior to the Effective Time, except
that (i) each of the assumed options and warrants will be exercisable for that
number of whole shares of QuadraMed Common Stock equal to the product of the
number of shares of Medicus Common Stock that were issuable upon exercise of
such option or warrant immediately prior to the Effective Time multiplied by
0.3565 and rounded down to the nearest whole number of shares of QuadraMed
Common Stock, (ii) the Director Options will be fully vested (with respect to
each of the Medicus Directors in the following amounts: Patrick C. Sommers --
428,000, William G. Brown -- 20,000, Jon E.M. Jacoby -- 125,000, John P. Kunz
- -- 35,000, Richard C. Jelinek -- 20,000, Risa Lavizzo-Mourey -- 50,000, Gail L.
Warden -- 20,000, Dorsey R. Gardner -- 30,000) and shall remain exercisable for
a period of three years following the Effective Time, and (iii) the per share
exercise price for the shares of QuadraMed Common Stock issuable upon exercise
of such assumed option or warrant will be equal to the quotient determined by
dividing the exercise price per share of Medicus Common Stock at which such
option or warrant was exercisable immediately prior to the Effective Time by
0.3565, rounded up to the nearest whole cent. See "THE MERGER AGREEMENT --
Effect on Employee Benefit Plans" and "THE MERGER -- Treatment of Stock Options
and Outstanding Warrants."

     Thomas F. McNulty, a director of QuadraMed, holds options to purchase
_______ shares of Medicus Common Stock which will be assumed by QuadraMed in the
Merger. These options will be converted into options to purchase shares of
Quadramed Common Stock on the same terms as other outstanding Medicus options.
 
     At the Effective Time of the Merger, QuadraMed will purchase and cancel the
Jelinek Warrants in exchange for shares of QuadraMed Common Stock with an
aggregate value of $1.12 million. The number of shares of QuadraMed Common Stock
issuable in exchange for the Jelinek Warrants will be determined by dividing
$1.12 million by the QuadraMed Stock Value as defined in the Merger Agreement.
If at the Effective Time of the Merger, the QuadraMed Stock Value exceeds
$27.60, then the number of shares of QuadraMed Common Stock issuable upon
cancellation of the Jelinek Warrants shall be equal to $1.12 million divided by
$27.60. If at the Effective Time of the Merger, the QuadraMed Stock Value is
less than $20.40, then the number of shares of QuadraMed Common Stock issuable
upon cancellation of the Jelinek Warrants shall be equal to $1.12 million
divided by $20.40.
 
     After the Effective Time, QuadraMed will indemnify and hold harmless the
present and former officers, directors, employees and agents of Medicus in
respect of acts or omissions occurring on or prior to the Effective Time to the
extent permitted by law and to the extent provided under Medicus' Amended and
Restated Certificate of Incorporation and Bylaws or any indemnification
agreement with Medicus' officers and directors to which Medicus is a party. For
two years after the Effective Time, QuadraMed will use its best efforts to
provide officers' and directors' liability insurance in respect of acts or
omissions occurring on or prior to the Effective Time covering each such person
currently covered by Medicus' officers' and directors' liability insurance
policy on terms substantially similar to those of such policy in effect on the
date of the Merger Agreement. QuadraMed shall not be obligated to pay premiums
in excess of 150% of the amount per annum Medicus paid in its last full fiscal
year, and if the insurance required by the Merger Agreement cannot be obtained,
QuadraMed shall obtain as much comparable insurance as possible for an annual
premium equal to such maximum amount. See "THE MERGER
AGREEMENT -- Indemnification."
 
APPROVAL OF THE BOARD OF DIRECTORS OF QUADRAMED; REASONS FOR THE MERGER
 
     At its November 9, 1997 meeting, the QuadraMed Board of Directors
determined that the Merger, upon the terms and conditions set forth in the
Merger Agreement, is fair to the holders of Medicus Common Stock and QuadraMed
Common Stock. Mr. Kenneth E. Jones did not participate in the meeting and Mr.
Thomas F. McNulty abstained from voting because he holds options to purchase
Medicus Common Stock. See "-- Interests of Certain Persons in the Merger." The
 
                                       34
<PAGE>   49
 
remaining QuadraMed directors have unanimously adopted the Merger Agreement and
the transactions contemplated thereby, including the Merger. See "-- Background
of the Merger."
 
     QuadraMed has identified what it believes are strategic and financial
benefits that the Merger would provide to each company and the stockholders,
employees and customers of each company. QuadraMed believes there exists a high
level of technical and functional compatibility between the products and
services offered by the companies, particularly in the areas of decision support
and clinical data systems. Medicus' products are PC-based and most are compliant
with the Windows(TM) operating environment, as are the systems offered by
QuadraMed. In addition, QuadraMed believes that the data captured by Medicus'
systems, when combined with that collected by QuadraMed's systems, is of
potential value and will enable QuadraMed to enhance the quality of data-based
products currently marketed by the two companies. Furthermore, access to an
increased number of customers who own only one or two of the products offered in
the combined companies' suite of products and services, represents a
cross-selling opportunity. QuadraMed also perceives the reputation of Medicus in
the marketplace as being widely known and well-regarded which may further
enhance QuadraMed's own reputation. QuadraMed generally believes the management
and employees of Medicus to be experienced and skilled in health care
information systems and, when combined with the management and resources of
QuadraMed, may result in a management team that is better able to create
stockholder value. Additionally, the management of the two companies believe
certain economies of scale, cost savings and operational leverage may be
achieved by reducing certain duplicative administrative functions.
 
     In reaching its determination, the QuadraMed Board consulted with
management, as well as its legal counsel, and considered a number of factors,
including the following material factors, both positive and negative:
 
          (i) the Board's knowledge of the business, operations, properties,
     assets, financial condition and operating results of QuadraMed;
 
          (ii) the reports and opinions of QuadraMed's management, its legal
     counsel and its independent auditors, including the result of their due
     diligence investigations concerning the business, operations and financial
     condition of Medicus;
 
          (iii) the effect on stockholder value of Medicus and QuadraMed
     continuing as independent entities compared to the effect of combining the
     two companies, in light of the financial condition and prospects of Medicus
     and the current economic and industry environment, including, but not
     limited to, the potential for increased value in the combined
     QuadraMed/Medicus enterprise;
 
          (iv) recent and current market prices of the QuadraMed Common Stock
     and the Medicus Common Stock;
 
          (v) the terms and conditions of the Merger Agreement and the related
     documents, which were the product of extensive arms-length negotiations;
 
          (vi) the premium represented by the Exchange Ratio over the price of
     the Medicus Common Stock;
 
          (vii) the compatibility of the respective business philosophies of
     QuadraMed and Medicus;
 
          (viii) the opportunity for Medicus stockholders to participate, as
     holders of QuadraMed Common Stock, in a larger, more diversified company;
 
          (ix) the risks that QuadraMed will not achieve the synergies and cost
     savings anticipated to be achieved in the Merger, including a reduction in
     expenses resulting from the combined purchasing power of the two companies;
 
          (x) the risk that the operations of the two companies would not be
     successfully integrated;
 
                                       35
<PAGE>   50
 
          (xi) the risk that key technical and management personnel might be
     lost prior to or after consummation of the Merger and the potential to
     mitigate this risk by negotiating the conversion of Medicus options into
     QuadraMed options;
 
          (xii) QuadraMed's future prospects for executing its business strategy
     and the likelihood that such prospects would be enhanced as a result of the
     Merger in light of the enhanced competition in the health care information
     systems industry;
 
          (xiii) the adverse effects on QuadraMed's and Medicus' businesses,
     operations and financial condition should it not be possible to consummate
     the Merger following public announcement that the Merger Agreement had been
     entered into; and
 
          (xiv) other risks associated with QuadraMed and Medicus' businesses,
     including those described above under "RISK FACTORS."
 
     The foregoing discussion of the information and factors considered by the
QuadraMed Board of Directors is not intended to be exhaustive but includes all
material factors considered by the QuadraMed Board of Directors. In view of the
variety of factors considered in connection with its evaluation of the Merger,
the QuadraMed Board of Directors did not find it practicable to and did not
quantify or otherwise assign relative weights to the specific factors considered
in reaching its determination. In addition, individual members of the QuadraMed
Board of Directors may have given different weights to different factors. In the
course of its deliberations, the QuadraMed Board of Directors did not establish
a range of value for Medicus; however, based on the factors outlined above, the
QuadraMed Board of Directors determined that the Merger is advisable and fair
and in the best interests of QuadraMed, Medicus and their respective
stockholders.
 
ANALYSIS OF QUADRAMED'S FINANCIAL ADVISOR
 
     In evaluating the proposed merger with Medicus, the QuadraMed Board of
Directors considered certain materials and analyses presented by Jefferies &
Company, Inc. ("Jefferies"), which acted as QuadraMed's financial advisor in
connection with the transaction. Jefferies was not instructed to, nor did it,
render an opinion as to the fairness of the transaction from a financial point
of view to the Board of Directors or stockholders of QuadraMed, and was not
engaged as an advisor to Medicus or its stockholders, which retained a separate
advisor. See "-- Opinion of Medicus' Financial Advisor." The analysis prepared
by Jefferies was limited to an accretion/dilution analysis at various possible
purchase prices and was based upon publicly-available information and
information provided by QuadraMed and Medicus. Had Jefferies been instructed to
deliver a fairness opinion or to advise Medicus or its stockholders, it might
have reviewed additional information and analyses which might have resulted in
materials and analyses that differed from that which was presented to
QuadraMed's Board of Directors. Furthermore, the materials and analyses
presented relied upon certain information which was provided to Jefferies by
QuadraMed and Medicus or was otherwise publicly available. Jefferies was not
asked to, and did not, independently verify the accuracy, completeness or fair
presentation of any financial or other information (including financial
projections, pro forma financial information and estimates), and assumed that
the information provided to it by QuadraMed and Medicus had been prepared on the
basis reasonably reflecting management's best currently available estimate and
good faith judgments as to the future performance of the respective companies
for all the periods specified therein. Jefferies was not asked to, and did not,
make an independent evaluation or appraisal or conduct a physical inspection of
any of the assets of QuadraMed or Medicus, nor was any such appraisal or
valuation made available to Jefferies.
 
     Jefferies, as part of its investment banking business, is regularly engaged
in the evaluation of capital structures, the evaluation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive bids, secondary distributions of listed and unlisted
securities, private placements, financial restructurings and other financial
services. Jefferies has provided investment banking services to QuadraMed in the
past for which it has received or expects to receive customary investment
banking fees and commissions, including acting as managing underwriter in
connection with QuadraMed's initial public offering in October 1996 and
follow-on equity offering in October 1997 and acting as financial advisor in
connection with QuadraMed's acquisition of Healthcare Recovery, Inc. (d.b.a.
Synergy HMC) in
 
                                       36
<PAGE>   51
 
April 1997, the RHP Mergers in December 1997 and for this Merger. QuadraMed
retained Jefferies as its advisor in connection with the Medicus transaction
due, in part, to Jefferies' experience in investment banking and general
familiarity with the health care information systems industry and certain of its
participants, including QuadraMed and Medicus. In the ordinary course of its
business, Jefferies and its affiliates may actively trade the securities of
QuadraMed or Medicus for their own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.
 
     The materials and analysis provided to QuadraMed's Board of Directors
contained (i) a summary description of Medicus, which among other things
described certain product and technology information, marketing agreements,
historical corporate transactions (including the March 1996 distribution of
Medicus' managed care business, Medicus' share repurchase from Mr. Richard
Jelinek and Medicus' reorganizations which took place in each of the fiscal
years ended May 31, 1996 and 1997), summary operating data, certain share and
option ownership, price and trading volume characteristics of Medicus' common
stock, monthly trading volume of the leading market makers in Medicus' common
stock and biographies of certain officers and directors; (ii) an overview of the
consideration to be paid to Medicus shareholders and the anticipated accretive
or dilutive effects of the transaction relative to the projected stand alone
results of QuadraMed as estimated by the research department of Jefferies; (iii)
a transaction analysis which depicted the pro forma effects of the Merger on the
projected combined results of operations of the two companies; (iv) certain
publicly available disclosure documents, including Medicus' most recent proxy,
10-K and 10-Q; and (v) an analysis of recent mergers and acquisitions in the
health care information systems industry which included, among other items,
certain ratios of the consideration paid relative to various operating results
of the acquired companies.
 
     Jefferies' advisory services and the materials and analysis presented to
QuadraMed's Board of Directors were provided for the information and assistance
of QuadraMed's Board of Directors in connection with its consideration of the
Merger and do not constitute a recommendation as to whether any holder of
Medicus Common Stock should vote for or against approval and adoption of the
Merger Agreement.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The receipt of the Merger Consideration for shares of Medicus Common Stock
will be a taxable transaction for U.S. federal income tax purposes and may be a
taxable transaction for foreign, state and local income tax purposes as well. A
Medicus stockholder will generally recognize gain or loss equal to the
difference between (i) the amount of cash, and, in the case of Medicus
stockholders receiving QuadraMed Common Stock, the fair market value of
QuadraMed Common Stock that the stockholder receives as a result of the Merger
and (ii) the stockholder's adjusted tax basis in the shares of Medicus Common
Stock that the stockholder exchanges in the Merger. Medicus will not recognize
any gain or loss as a result of the Merger for U.S. federal income tax purposes.
 
     THE FOREGOING IS NOT INTENDED TO BE A COMPREHENSIVE DISCUSSION OF ALL
POSSIBLE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER.
FURTHERMORE, THE PROXY STATEMENT/PROSPECTUS DOES NOT PROVIDE INFORMATION
REGARDING THE TAX CONSEQUENCES OF THE MERGER UNDER THE TAX LAWS OF ANY STATE OR
OF ANY LOCAL OR FOREIGN JURISDICTION. MEDICUS STOCKHOLDERS ARE URGED TO CONSULT
THEIR OWN TAX ADVISORS WITH RESPECT TO SPECIFIC TAX CONSEQUENCES OF THE MERGER.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for as a purchase for financial reporting
purposes in accordance with GAAP. This method will require the allocation of the
purchase price to the various assets acquired and liabilities assumed based on
the fair market values of those assets and liabilities.
 
     QuadraMed received an appraisal of certain intangible assets which will be
acquired in the Merger which indicated that approximately $35,000,000 of the
intangible assets to be acquired consist of in-process research and development.
In the opinion of management, the acquired in-process research and development
had not
 
                                       37
<PAGE>   52
 
yet reached technological feasibility and had no alternative future use.
Accordingly, QuadraMed expects to record a non-recurring charge of approximately
$35,000,000 in its fourth quarter ended December 31, 1997. The remaining
intangible assets are expected to be amortized over a seven-year period.
 
CERTAIN LEGAL MATTERS
 
     No federal or state regulatory requirements or approvals (other than those
which arose in connection with the registration of QuadraMed Common Stock to be
issued in the Merger and the effectiveness of this Proxy Statement/Prospectus
and certain notice filings after the Effective Time) must be complied with or
obtained in connection with the Merger.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
     All QuadraMed Common Stock issued in connection with the Merger will be
freely transferable, except that any QuadraMed Common Stock received by persons
who are deemed to be "affiliates" (as such term is defined under the Securities
Act) of Medicus or QuadraMed prior to the Merger may be sold by them only in
transactions permitted by the resale provisions of Rule 145 under the Securities
Act with respect to affiliates of Medicus, or Rule 144 under the Securities Act
with respect to persons who are or become affiliates of QuadraMed, or as
otherwise permitted under the Securities Act. Persons who may be deemed to be
affiliates of Medicus or QuadraMed generally include individuals or entities
that control, are controlled by, or are under common control with, such party
and may include certain officers and directors of such party as well as
principal stockholders of such party.
 
     Affiliates of Medicus may not sell their shares of QuadraMed Common Stock
acquired in connection with the Merger, except pursuant to an effective
registration statement under the Securities Act covering such shares or in
compliance with Rule 145 (or Rule 144 under the Securities Act in the case of
persons who become affiliates of QuadraMed) or another applicable exemption from
the registration requirements of the Securities Act. In general, under Rule 145,
for one year following the Effective Time an affiliate (together with certain
related persons) would be entitled to sell shares of QuadraMed Common Stock
acquired in connection with the Merger only through unsolicited "brokers'
transactions" or in transactions directly with a "market maker," as such terms
are defined in Rule 144. Additionally, the number of shares to be sold by an
affiliate (together with certain related persons and certain persons acting in
concert with an affiliate) within any three-month period for purposes of Rule
145 may not exceed the greater of 1% of the outstanding shares of QuadraMed
Common Stock or the average weekly trading volume of such stock during the four
calendar weeks preceding such sale. Rule 145 would only remain available,
however, to such former Medicus affiliates if QuadraMed remained current with
its informational filings with the Commission under the Exchange Act. One year
after the Effective Time, a former affiliate of Medicus would be able to sell
such QuadraMed Common Stock without such manner of sale or volume limitations
provided that QuadraMed was current with its Exchange Act informational filings
and such affiliate was not then an affiliate of QuadraMed. Two years after the
Effective Time, a former affiliate of Medicus would be able to sell such shares
of QuadraMed Common Stock without any restrictions so long as such affiliate had
not been an affiliate of QuadraMed for at least three months prior thereto.
 
LISTING
 
     It is a condition to the obligations of QuadraMed and Medicus to consummate
the Merger that application shall have been made to the Nasdaq National Market
to list the shares of QuadraMed Common Stock to be issued in connection with the
Merger.
 
APPRAISAL RIGHTS
 
     Record holders of Medicus Common Stock are entitled to appraisal rights
under Section 262 ("Section 262") of the Delaware General Corporation Law (the
"DGCL"). The following discussion represents a summary of the material
provisions of Section 262, and is qualified in its entirety by reference to the
full text of Section 262, which is reprinted in its entirety as Annex C to this
Proxy Statement/Prospectus. A person
 
                                       38
<PAGE>   53
 
having a beneficial interest in shares of Medicus Common Stock held of record in
the name of another person, such as a broker or nominee, must act promptly to
cause the record holder to follow the steps summarized below properly and in a
timely manner to perfect the appraisal rights provided under Section 262.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Special Meeting, not less than 20
days prior to the meeting, a constituent corporation must notify each of the
holders of its stock (who was a stockholder on the record date for such meeting)
for which appraisal rights are available that such appraisal rights are
available and include in each such notice a copy of Section 262. THIS PROXY
STATEMENT/PROSPECTUS SHALL CONSTITUTE SUCH NOTICE TO THE RECORD HOLDERS OF
MEDICUS COMMON STOCK THAT APPRAISAL RIGHTS ARE AVAILABLE. ANY SUCH STOCKHOLDER
WHO WISHES TO EXERCISE SUCH APPRAISAL RIGHTS SHOULD REVIEW THE FOLLOWING
DISCUSSION AND ANNEX C CAREFULLY, BECAUSE FAILURE TO TIMELY AND STRICTLY COMPLY
WITH THE PROCEDURES SPECIFIED MAY RESULT IN THE LOSS OF APPRAISAL RIGHTS UNDER
THE DGCL.
 
     Under the DGCL, a record holder of shares of Medicus Common Stock who makes
the demand described below with respect to such shares, who continuously is the
record holder of such shares through the Effective Time, who otherwise complies
with the statutory requirements set forth in Section 262 and who neither votes
in favor of approval of the Merger Agreement and the Merger nor consents thereto
in writing will be entitled to have his or her shares of Medicus Common Stock
appraised by the Delaware Court of Chancery and to receive payment of the "fair
value" of such shares as described below. Such holders are, in such
circumstances, entitled to appraisal rights because they hold stock of a
constituent corporation to the Merger and may be required by the Merger
Agreement to accept cash as a portion or all of the Merger Consideration. Since
holders of shares of Medicus Common Stock wishing to exercise appraisal rights
must not vote in favor of approval of the Merger Agreement and the Merger, such
holders should not deliver unmarked proxies (i.e., proxies without instructions)
to Medicus as such proxies will be voted FOR such approval. See "THE SPECIAL
MEETING -- Record Date; Voting Rights; Proxies."
 
     A holder of shares of Medicus Common Stock wishing to exercise his or her
appraisal rights must deliver to the Secretary of Medicus, before the vote on
the Merger Agreement at the Special Meeting, a written demand for appraisal of
his or her shares of Medicus Common Stock. Merely voting or delivering a proxy
directing a vote against approval of the Merger Agreement and the Merger will
not constitute a demand for appraisal. A written demand is essential. Such
written demand must reasonably inform Medicus of the identity of the holder and
that such holder intends thereby to demand appraisal of the holder's shares. All
written demands for appraisal of Medicus Common Stock should be sent or
delivered to Medicus, One Rotary Center, Suite 1111, Evanston, Illinois 60201,
Attn: Secretary. In addition, a holder of shares of Medicus Common Stock wishing
to exercise his or her appraisal rights must hold such shares of record on the
date the written demand for appraisal is made and must hold such shares
continuously through the Effective Time. Stockholders who hold their shares of
Medicus Common Stock in brokerage accounts or other nominee forms and who wish
to exercise appraisal rights must take all necessary steps in order that a
demand for appraisal is made by the record holder of such shares and are urged
to consult with their brokers to determine the appropriate procedures for the
making of a demand for appraisal by the record holder.
 
     Within 10 days after the Effective Time, the Surviving Corporation (as
defined in "The Merger Agreement -- The Merger") must send a notice as to the
effectiveness of the Merger to each holder of shares of Medicus Common Stock who
has satisfied the appropriate provisions of Section 262 and who is entitled to
appraisal rights under Section 262. Within 120 days after the Effective Time,
any holder of record of shares of Medicus Common Stock who has complied with the
requirements for exercise of appraisal rights will be entitled, upon written
request, to receive from the Surviving Corporation a statement setting forth (i)
the aggregate number of shares of Medicus Common Stock not voted in favor of the
Merger Agreement and with respect to which demands for appraisal have been
received and (ii) the aggregate number of holders of such shares. Any such
statement must be mailed within 10 days after a written request therefor has
been received by the Surviving Corporation.
 
                                       39
<PAGE>   54
 
     Within 120 days after the Effective Time, but not thereafter, the Surviving
Corporation or any holder of shares of Medicus Common Stock who has complied
with the foregoing procedures and who is entitled to appraisal rights under
Section 262 may file a petition in the Delaware Court of Chancery demanding a
determination of the "fair value" of such shares. The Surviving Corporation is
not under any obligation to file a petition with respect to the appraisal of the
"fair value" of the shares of Medicus Common Stock and neither QuadraMed nor
Medicus presently expects that the Surviving Corporation will file such a
petition. Accordingly, it is the obligation of the holders of Medicus Common
Stock to initiate all necessary action to perfect their appraisal rights within
the time prescribed in Section 262. A holder of shares of Medicus Common Stock
will fail to perfect, or effectively lose, his or her right to appraisal if no
petition for appraisal of shares of Medicus Common Stock is filed within 120
days after the Effective Time.
 
     If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine the holders of shares of
Medicus Common Stock entitled to appraisal rights and will appraise the "fair
value" of the shares of Medicus Common Stock, exclusive of any element of value
arising from the accomplishment or expectation of the Merger. Holders
considering seeking appraisal should be aware that the "fair value" of their
shares of Medicus Common Stock as determined under Section 262 could be more
than, the same as, or less than the value of the Merger Consideration they would
receive if they did not seek appraisal. The Delaware Supreme Court has stated
that "proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissible in court" should
be considered in the appraisal proceedings. In addition, Delaware courts have
decided that the statutory appraisal remedy, depending on factual circumstances,
may or may not be a dissenter's exclusive remedy.
 
     The Delaware Court of Chancery will determine the amount of interest, if
any, to be paid upon the amounts to be received by persons whose shares of
Medicus Common Stock have been appraised. The costs of the action may be
determined by such court and taxed upon the parties as the court deems
equitable. The Delaware Court of Chancery may also order that all or a portion
of the expenses incurred by any holder of shares of Medicus Common Stock in
connection with an appraisal, including, without limitation, reasonable
attorneys' fees and the fees and expenses of experts utilized in the appraisal
proceeding, be charged pro rata against the value of all of the shares of
Medicus Common Stock entitled to appraisal.
 
     If any holder of shares of Medicus Common Stock who demands appraisal of
his or her shares under Section 262 fails to perfect, or effectively withdraws
or loses, his or her right to appraisal, as provided in the DGCL, such
stockholder will receive the Merger Consideration in accordance with the Merger
Agreement. A holder may withdraw his or her demand for appraisal by delivering
to the Surviving Corporation a written withdrawal of his or her demand for
appraisal and acceptance of the Merger, except that any such attempt to withdraw
made more than 60 days after the Effective Time will require the written
approval of the Surviving Corporation. Failure to follow the steps required by
Section 262 for perfecting appraisal rights may result in the loss of such
rights.
 
     Any holder of shares of Medicus Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote the shares of Medicus Common Stock subject to such demand for
any purpose or be entitled to the payment of dividends or other distributions on
those shares (except dividends or other distributions payable to holders of
record of shares of Medicus Common Stock as of a date prior to the Effective
Time).
 
     Shares of Medicus Common Stock held by any holder who shall have failed to
perfect or who effectively shall have withdrawn or lost his or her rights to
appraisal of such shares of Medicus Common Stock under Section 262 shall be
deemed to have been converted into and to have become exchangeable, as of the
Effective Time, for the right to receive, without any interest thereon, shares
of QuadraMed Common Stock based on the Exchange Ratio, as if such shares were
covered by Non-Elections, upon surrender of the certificate or certificates that
formerly evidenced such shares of Medicus Common Stock. See "THE MERGER
AGREEMENT -- Election for Shares or Cash."

                   THE STOCK PURCHASE AGREEMENTS AND WARRANTS
 
     On November 9, 1997, QuadraMed and certain stockholders of Medicus (the
"Selling Stockholders") entered into Stock Purchase Agreements pursuant to which
QuadraMed acquired 56.7% of the outstanding shares of Medicus Common Stock. In
consideration for the sale of the Medicus Common Stock to QuadraMed, QuadraMed
agreed to pay to the Selling Stockholders $7.50 per share, in cash, without
interest, together with a warrant (the "Warrant") entitling the Selling
Stockholders to acquire 0.3125 shares of QuadraMed Common Stock for each share
of Medicus Common Stock sold. The aggregate purchase price paid by QuadraMed to
the Selling Stockholders was approximately $23.3 million in cash plus Warrants
to purchase an aggregate of 972,220 shares of QuadraMed Common Stock as
described in the following paragraphs. The Selling Stockholders included Richard
C. Jelinek, William G. Brown, Jon E.M. Jacoby, Gail L. Warden and Dorsey R.
Gardner, all of whom are directors of Medicus.
 
     The Warrants entitle the Selling Stockholders to purchase QuadraMed Common
Stock at a price of $24.00 per share (the closing price on the last trading day
prior to execution of the Stock Purchase Agreements), which would provide them
with additional value in the event the market price of QuadraMed Common Stock
were to increase above $24.00 per share. If at the Effective Time of the Merger,
the QuadraMed Stock Value (as defined below) exceeds $27.60, then the number of
shares of QuadraMed Common Stock issuable upon exercise of the Warrants shall be
adjusted downward such that the number of shares of QuadraMed Common Stock
issuable upon exercise of a Warrant shall be X, where X is equal to the Warrant
Value (as defined below) divided by the difference of (i) the QuadraMed Stock
Value minus (ii) $24.00. For purposes of the Warrants, the term "QuadraMed Stock
Value" means the price per share equal to the average of the closing prices of
QuadraMed Common Stock during the fifteen (15) days prior to the second day
prior to the date of the Special Meeting and the term "Warrant Value" means the
product obtained by multiplying $3.60 by the initial number of shares of
QuadraMed Stock issuable under the Warrants.
 
     The Warrants were intended to provide to the Selling Stockholders the
opportunity to benefit from any increase in the price of the QuadraMed Common
Stock to the same extent as other holders of Medicus Common Stock who may elect
to receive the Merger Consideration in the form of QuadraMed Common Stock. To
the extent that a Warrant is not exercised at the Effective Time or the number
of shares issuable upon exercise of a Warrant is limited as set forth in the
following paragraph, the portion of a Warrant that is unexercised or subject to
the limitations set forth in the following paragraph shall terminate and shall
be void and of no further force or effect. The shares of QuadraMed Common Stock
issuable upon exercise of Warrants will be registered pursuant to a registration
statement on Form S-3 to be filed by QuadraMed.
 
     In no event shall the aggregate number of shares of QuadraMed Common Stock
which QuadraMed is obligated to issue (1) upon conversion of the Warrants and
(2) in exchange for outstanding shares of Medicus Common Stock pursuant to the
Merger Agreement, exceed 1,800,000 shares of QuadraMed Common Stock. In the
event that the total number of shares of QuadraMed Common Stock which holders of
Warrants and holders of Medicus Common Stock have elected to receive as
described in clauses (1) and (2) in the immediately preceding sentence exceeds
1,800,000, QuadraMed shall only be required to issue 1,800,000 shares of
QuadraMed Common Stock and such holders shall be entitled to receive shares of
QuadraMed Common Stock equal to each holder's pro rata portion of the total
amount of shares issued by QuadraMed as described in clauses (1) and (2), based
on the total number of shares each holder elected to receive. See "THE MERGER
AGREEMENT -- Limitation on Shares Issuable."
 
     In lieu of the cash payment described above, QuadraMed delivered to William
G. Brown, a Selling Stockholder and director of Medicus, a promissory note in
the amount of $1,620,075 (which note was paid on January 5, 1998) in exchange
for Mr. Brown's transfer to QuadraMed of 216,010 shares of Medicus Common Stock.
 
     In connection with the Merger, Patrick Sommers and Richard C. Jelinek,
option holders of Medicus, granted irrevocable proxies to QuadraMed with respect
to all shares of Medicus Common Stock which are issuable upon exercise of
outstanding options or warrants to purchase Medicus Common Stock owned by them
(the "Option Shares"). Pursuant to the proxies, QuadraMed is empowered to
exercise all voting and other
 
                                       41
<PAGE>   56
 
rights with respect to the Option Shares as it deems proper in respect of any
matter at a meeting of stockholders, or any written consent in lieu of a meeting
of stockholders.

                              THE SPECIAL MEETING
 
PURPOSE OF THE SPECIAL MEETING
 
     At the Special Meeting, holders of record of Medicus Common Stock entitled
to vote as of the Medicus Record Date (as defined below) will consider and vote
upon a proposal to approve and adopt the Merger Agreement and such other matters
as may properly be brought before the Special Meeting.
 
     THE BOARD OF DIRECTORS OF MEDICUS HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND RECOMMENDS A VOTE FOR APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT.
 
RECORD DATE; VOTING RIGHTS; PROXIES
 
     The Medicus Board has established a Record Date Committee (consisting of
Messrs. Brown and Sommers) which has fixed the close of business on
  , 1998 as the record date (the "Medicus Record Date") for determining holders
of Medicus Common Stock entitled to notice of and to vote at the Special
Meeting.
 
     As of the Medicus Record Date, there were [          ] shares of Medicus
Common Stock issued and outstanding, each of which entitles the holder thereof
to one vote. All shares of Medicus Common Stock represented by properly executed
proxies will, unless such proxies have been previously revoked, be voted in
accordance with the instructions indicated in such proxies. IF NO INSTRUCTIONS
ARE INDICATED, SUCH SHARES OF MEDICUS COMMON STOCK WILL BE VOTED FOR APPROVAL
AND ADOPTION OF THE MERGER AGREEMENT.
 
     Votes cast by proxy or in person at the Special Meeting will be tabulated
by the election inspectors appointed for the meeting who will determine whether
or not a quorum is present. Where, as to any matter submitted to the
stockholders for a vote, proxies are marked as abstentions (or stockholders
appear in person but abstain from voting), such abstentions will be treated as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum but as unvoted for purposes of determining the approval of
any matter submitted to the stockholders for a vote. If a broker indicates on
the proxy that it does not have discretionary authority as to certain shares to
vote on a particular matter, those shares will be treated as shares that are
present and entitled to vote for purposes of determining the presence of a
quorum but will not be considered as present and entitled to vote with respect
to that matter.
 
SOLICITATION OF PROXIES
 
     Medicus will bear its own cost of solicitation of proxies. In addition to
the use of the mails, proxies may be solicited by the directors and officers of
Medicus by personal interview, telephone, telegram or E-mail. Such directors and
officers will not receive additional compensation for such solicitation but may
be reimbursed for out-of-pocket expenses incurred in connection therewith.
Arrangements may also be made with brokerage firms and other custodians,
nominees and fiduciaries to forward solicitation materials to the beneficial
owners of shares of Medicus Common Stock held of record by such persons, in
which case Medicus will reimburse such brokerage firms, custodians, nominees and
fiduciaries for reasonable out-of-pocket expenses incurred by them in connection
therewith.
 
QUORUM
 
     The presence in person or by properly executed proxy of holders of a
majority of the issued and outstanding shares of Medicus Common Stock entitled
to vote as of the Medicus Record Date is necessary to constitute a quorum at the
Special Meeting. Under applicable Delaware Law, abstentions and "broker
non-votes" (that is, proxies from brokers or nominees indicating that such
persons have not received instructions from the beneficial owner or other person
entitled to vote shares as to a matter with respect to which the brokers or
nominees do not have discretionary power to vote) will be treated as present for
purposes of determining the presence of a quorum at the Special Meeting.
 
                                       43
<PAGE>   58
 
REQUIRED VOTE
 
     The approval of the Merger requires the affirmative vote of the holders of
a majority of the outstanding shares of Medicus Common Stock. QuadraMed, which
acquired 56.7% of the outstanding shares of Medicus Common Stock pursuant to
Stock Purchase Agreements with certain stockholders of Medicus, will vote its
shares of Medicus Common Stock in favor of approval and adoption of the Merger
Agreement and the transactions contemplated thereby. In addition, in connection
with the Merger, Patrick Sommers and Richard C. Jelinek, option holders of
Medicus, granted irrevocable proxies to QuadraMed with respect to all shares of
Medicus Common Stock which are issuable upon exercise of outstanding options or
warrants to purchase Medicus Common Stock owned by them (the "Option Shares").
Pursuant to the proxies, QuadraMed is empowered to exercise all voting and other
rights with respect to the Option Shares as it deems proper in respect of any
matter at a meeting of stockholders, or any written consent in lieu of a meeting
of stockholders. As a result, QuadraMed's affirmative vote for approval and
adoption of the Merger Agreement is sufficient to approve the Merger. No
provision has been made in the Merger Agreement which requires that the Merger
be approved by a majority of the unaffiliated Medicus stockholders.
 
     A proposal to adjourn the Special Meeting to solicit additional proxies
requires the affirmative vote of the holders of a majority of Medicus Common
Stock present in person or by proxy at the Special Meeting. As of the Medicus
Record Date, there were [          ] shares of Medicus Common Stock outstanding
and entitled to vote held by approximately [          ] stockholders of record.
As of the Medicus Record Date, QuadraMed and directors and officers of Medicus
and their affiliates as a group beneficially owned [          ] shares of
Medicus Common Stock, or approximately [          ]% of those shares of Medicus
Common Stock outstanding as of such date.
 
     THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO THE STOCKHOLDERS OF MEDICUS. ACCORDINGLY, STOCKHOLDERS ARE URGED TO READ AND
CAREFULLY CONSIDER THE INFORMATION PRESENTED IN THIS PROXY STATEMENT/PROSPECTUS,
AND TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED PROXY IN THE
ENCLOSED POSTAGE PAID ENVELOPE.
 
                                   THE MERGER
 
GENERAL
 
     The Merger Agreement provides that the Merger will be consummated if the
approval of the Medicus stockholders required therefor is obtained and all other
conditions to the Merger are satisfied or waived. Pursuant to the Merger
Agreement, QuadraMed, which owns 56.7% of the Medicus Common Stock, has agreed
and intends to vote all of its shares of Medicus Common Stock in favor of the
Merger. As a result, QuadraMed's affirmative vote for approval and adoption of
the Merger Agreement is sufficient to approve the Merger. See "THE MERGER
AGREEMENT -- Conditions to Consummation of the Merger."
 
     Upon consummation of the Merger, Merger Sub, a wholly owned subsidiary of
QuadraMed, will be merged with and into Medicus, and Medicus will become a
wholly owned subsidiary of QuadraMed. Upon consummation of the Merger, each
outstanding share of Medicus Common Stock (other than shares owned by Medicus as
treasury stock or by its subsidiaries or shares owned by QuadraMed or any direct
or indirect wholly owned subsidiary of QuadraMed, all of which will be canceled)
will be automatically converted into the right to receive any of (i) $7.50 in
cash, without interest (the "Per Share Cash Amount"); or (ii) 0.3125 shares of
QuadraMed Common Stock (the "Exchange Ratio"), subject to adjustment and certain
limitations as described in the Merger Agreement; or (iii) a combination of
shares of QuadraMed Common Stock and cash (collectively, the "Merger
Consideration"). The Exchange Ratio is subject to the following adjustments: if
(1) the QuadraMed Stock Value exceeds $27.60, then the Exchange Ratio shall be
the quotient obtained by dividing (A) $8.625 by (B) the QuadraMed Stock Value,
and (2) the QuadraMed Stock Value is less than $24.00, then the Exchange Ratio
shall be the quotient obtained by dividing (A) $7.50 by (B) the QuadraMed Stock
Value. Additionally, if the QuadraMed Stock Value is less than $20.40, then
QuadraMed may elect, at
 
                                       44
<PAGE>   59
 
its sole discretion, to cause all or any portion of the shares of Medicus Common
Stock to be converted into the Per Share Cash Amount (the "QuadraMed Cash
Election"). In the event of a QuadraMed Cash Election in which less than all of
the outstanding shares of Medicus Common Stock will be converted into cash, the
shares of Medicus Common Stock to be converted into cash as a result of the
QuadraMed Cash Election will be selected pro rata according to the number of
shares with respect to which a Stock Election has been made. The "QuadraMed
Stock Value" is equal to the average of the closing prices of QuadraMed Common
Stock during the fifteen (15) days prior to the second day prior to the date of
the Special Meeting.
 
     Each record holder of Medicus Common Stock may elect to receive the Per
Share Cash Amount (a "Cash Election"), shares of QuadraMed Common Stock (a
"Stock Election") or a combination of both. Shares of Medicus Common Stock for
which no election is received or for which a stockholder has indicated no
preference for cash or shares (a "Non-Election") will automatically be
converted into the right to receive QuadraMed Common Stock. The maximum number
of shares of QuadraMed Common Stock which QuadraMed is obligated to issue in the
Merger and upon exercise of the Warrants is 1,800,000 shares. If the aggregate
number of shares of QuadraMed Common Stock issuable pursuant to Stock Elections
and issuable upon exercise of the Warrants exceeds 1,800,000, the shares
issuable upon consummation of the Merger and exercise of the Warrants will be
allocated on a  pro rata basis. See "THE MERGER AGREEMENT -- Limitation on
Shares Issuable."
 
     Based upon the capitalization of Medicus and QuadraMed (as adjusted for and
assuming the issuance of 1,800,000 shares of QuadraMed Common Stock and assuming
no adjustment of the Exchange Ratio) as of the Medicus Record Date, the
stockholders of Medicus will own approximately [     ]% of the outstanding
QuadraMed Common Stock following consummation of the Merger. Such percentage
could change depending on the number of shares of QuadraMed Common Stock and
Medicus Common Stock issued upon exercise of outstanding Medicus and QuadraMed
stock options and warrants or otherwise issued prior to the Effective Time.
 
EFFECTIVE TIME
 
     The Effective Time of the Merger will occur upon the filing of a
Certificate of Merger with the Secretary of State of the State of Delaware (the
"Certificate of Merger"). The filing of the Certificate of Merger will occur on
the date of closing of the transactions contemplated in the Merger Agreement
(the "Closing Date"). QuadraMed and Medicus currently expect that the closing
will occur promptly after the Special Meeting. The Merger Agreement may be
terminated by either party if the Merger has not been consummated on or before
May 1, 1998 and under certain other conditions. See "THE MERGER
AGREEMENT -- Conditions to Consummation of the Merger," "-- Termination;
Expenses; Amendment; Waiver."
 
ELECTION PROCEDURES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
     Each record holder of Medicus Common Stock may elect to receive the Per
Share Cash Amount, shares of QuadraMed Common Stock or a combination of both by
submitting a Form of Election to the Exchange Agent no later than the Election
Deadline. Record holders who indicate no preference on the Form of Election or
who do not submit a Form of Election prior to the Election Deadline will
automatically have their shares of Medicus Common Stock converted into the right
to receive shares of QuadraMed Common Stock at the Effective Time (subject to
QuadraMed's right to make the QuadraMed Cash Election and QuadraMed's obligation
to issue no more than 1,800,000 shares of QuadraMed Common Stock in the Merger).
 
     Promptly after the Effective Time, QuadraMed will instruct the Exchange
Agent to mail to each holder of record of certificates which formerly
represented Medicus Common Stock (the "Certificates") as soon as practicable a
letter of transmittal and instructions for use in effecting the surrender of
Certificates. Upon receipt of such Certificates, the Exchange Agent will
deliver, as the case may be, (i) the Per Share Cash Amount and/or (ii) whole
shares of QuadraMed Common Stock to such stockholder and cash in lieu of
fractional shares to which such holder would otherwise be entitled pursuant to
the terms of the Merger Agreement and in accordance with the letter of
transmittal, together with any dividends or other distributions to which such
stockholder is entitled, without interest. See "THE MERGER AGREEMENT -- Election
for Shares or Cash."
 
                                       45
<PAGE>   60
 
     After the Effective Time, there will be no further transfers of Medicus
Common Stock on the stock transfer books of Medicus. If a Certificate
representing Medicus Common Stock is presented for transfer, it will be canceled
and exchanged as provided in the Merger Agreement. See "THE MERGER
AGREEMENT -- Surrender and Payment."
 
     After the Effective Time and until surrendered, Certificates which formerly
represented shares of Medicus Common Stock will be deemed for all corporate
purposes, other than the payment of dividends and distributions, to evidence
ownership of the number of full shares of QuadraMed Common Stock or the Per
Share Cash Amount, as the case may be, into which such shares of Medicus Common
Stock were converted at the Effective Time. After the Effective Time, no
dividends or other distributions, if any, payable to holders of QuadraMed Common
Stock will be paid to the holders of any Certificates until such Certificates
are surrendered. Upon surrender of such Certificates, all such declared
dividends and distributions with a record date after the Effective Time will be
paid to the holder of record of certificates representing the full shares of
QuadraMed Common Stock represented by the certificate issued in exchange
therefor, without interest. See "THE MERGER AGREEMENT -- Surrender and Payment."
It should be noted that QuadraMed has never declared any cash dividends on the
QuadraMed Common Stock. QuadraMed currently intends to retain future earnings,
if any, to fund the development and growth of its business and does not
anticipate paying any cash dividends on the QuadraMed Common Stock in the
foreseeable future. In addition, QuadraMed's credit agreement contains
provisions that restrict the payment of dividends.
 
TREATMENT OF STOCK OPTIONS AND OUTSTANDING WARRANTS
 
     At the Effective Time, the obligations under the Medicus Stock Option Plans
and the TriHealth Warrant will be assumed by QuadraMed. Each option so assumed
by QuadraMed shall continue to have, and be subject to, the same terms and
conditions set forth in the Medicus Stock Option Plans and the TriHealth
Warrant shall continue to have, and be subject to, the same terms and
conditions set forth therein, immediately prior to the Effective Time, except
that (i) each of the assumed options and warrants will be exercisable for that
number of whole shares of QuadraMed Common Stock equal to the product of the
number of shares of Medicus Common Stock that were issuable upon exercise of
such option or warrant immediately prior to the Effective Time multiplied by
0.3565, rounded down to the nearest whole number of shares of QuadraMed Common
Stock, (ii) the Director Options will be fully vested and shall remain
exercisable for a period of three years after the Effective Time (or three
years after termination of employment in the case of Mr. Sommers) and (iii) the
per share exercise price for the shares of QuadraMed Common Stock issuable upon
exercise of such assumed option or warrant will be equal to the quotient
determined by dividing the exercise price per share of Medicus Common Stock at
which such option or warrant was exercisable immediately prior to the Effective
Time by 0.3565, rounded up to the nearest whole cent.
        
     At the Effective Time, the Jelinek Warrants shall be purchased and
cancelled by QuadraMed in exchange for QuadraMed Common Stock. See "SPECIAL
FACTORS -- Interests of Certain Persons in the Merger."
 
     HOLDERS OF MEDICUS COMMON STOCK SHOULD NOT FORWARD STOCK CERTIFICATES TO
THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS. HOLDERS OF
MEDICUS COMMON STOCK SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED
PROXY.

                              THE MERGER AGREEMENT
 
     The following description of the Merger Agreement is necessarily a summary
thereof and is therefore qualified in its entirety by reference to the Merger
Agreement, a copy of which is attached to this Proxy Statement/Prospectus as
Annex A and incorporated herein by reference. Stockholders of Medicus are urged
to read the Merger Agreement in its entirety.
 
THE MERGER
 
     The Merger Agreement provides that, subject to the approval of the Merger
by the stockholders of Medicus and the satisfaction or waiver of the other
conditions to the Merger, a newly formed subsidiary of QuadraMed ("Merger Sub")
will be merged with and into Medicus in accordance with Delaware law, whereupon
the separate existence of Merger Sub will cease and Medicus will be the
surviving corporation of the Merger (the "Surviving Corporation"). Merger Sub
was formed solely to complete the Merger. At the Effective Time, the conversion
of Medicus Common Stock and the conversion of shares of the common stock of
Merger Sub pursuant thereto will be effected as described below. The Certificate
of Incorporation and Bylaws of Merger Sub will become the Certificate of
Incorporation and Bylaws of the Surviving Corporation and may thereafter be
amended and/or restated as provided therein and by Delaware law. The directors
and officers of Merger Sub shall become the directors and officers of the
Surviving Corporation.
 
TERMS OF THE MERGER
 
     At the Effective Time, each share of Medicus Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares owned by
Medicus as treasury stock or by its subsidiaries or shares owned by QuadraMed or
any direct or indirect wholly owned subsidiary of QuadraMed, all of which will
be cancelled) will be canceled and extinguished and be converted automatically
into the right to receive any of (i) the Per Share Cash Amount; or (ii) the
Exchange Ratio; or (iii) a combination of shares of QuadraMed Common Stock and
the Per Share Cash Amount. The Exchange Ratio is subject to the following
adjustments: (i) if the QuadraMed Stock Value exceeds $27.60, then the Exchange
Ratio shall be the quotient obtained by dividing (A) $8.625 by (B) the QuadraMed
Stock Value, and (ii) if the QuadraMed Stock Value is less than $24.00, then the
Exchange Ratio shall be the quotient obtained by dividing (A) $7.50 by (B) the
QuadraMed Stock Value; provided further, however, that if the QuadraMed Stock
Value is less than $20.40, then QuadraMed may, at its sole discretion, elect to
have all or any portion of the shares of Medicus Common Stock converted into the
Per Share Cash Amount (the "QuadraMed Cash Election"). In the event of the
QuadraMed Cash Election in which less than all of the outstanding shares of
Medicus Common Stock will be converted into cash, the shares of Medicus Common
Stock to be converted into cash as a result of the QuadraMed Cash Election will
be selected pro rata according to the number of shares with respect to which a
Stock Election (as defined in "-- Election for Shares or Cash") has been made.
The amounts paid in the Merger in exchange for shares of Medicus Common Stock
shall be referred to herein as the "Merger Consideration."
 
     At the Effective Time, the Medicus 1989 Stock Option Plan, the Medicus 1991
Stock Option Plan, the Medicus 1993 Stock Option Plan, the Medicus 1993
Performance Stock Option Plan, the Medicus 1994 Stock Option Plan, the Medicus
1994 Directors' Stock Option Plan, the Medicus 1995 RCM Stock Option Plan, the
Medicus 1996 C.E.O. Stock Option Plan, the Medicus 1996 C.E.O. Replacement Stock
Option Plan, the Medicus 1996 C.E.O. Special Stock Option Plan, the Medicus 1997
Employee Stock Option and Restricted Stock Plan, and the Medicus 1997 Directors'
Stock Option Plan (collectively, the "Medicus Stock Option Plans"), the
TriHealth Warrant and all options or rights to purchase Medicus Common Stock
then outstanding under the Medicus Stock Option Plans, and the TriHealth
Warrant, shall be assumed by QuadraMed.
 
FRACTIONAL SHARES
 
     No fraction of a share of QuadraMed Common Stock will be issued in the
Merger. In lieu of any fractional shares that would otherwise be issuable in the
Merger in exchange for shares of Medicus Common
 
                                       47
<PAGE>   62
 
Stock, QuadraMed shall pay the proportionate amount of the Per Share Cash Amount
that would be payable in respect of such fractional share.
 
LIMITATION ON SHARES ISSUABLE
 
     In no event shall the aggregate number of shares of QuadraMed Common Stock
which QuadraMed is obligated to issue in the aggregate (i) upon the exercise of
the Warrants and (ii) in exchange for outstanding shares of Medicus Common Stock
pursuant to the Merger Agreement exceed a total of 1,800,000 shares. In the
event that the aggregate number of shares of QuadraMed Common Stock that holders
of Warrants and holders of Medicus Common Stock have elected to receive as
described in clauses (i) and (ii) in the immediately preceding sentence exceeds
1,800,000, QuadraMed shall only be required to issue 1,800,000 shares of
QuadraMed Common Stock and such holders shall be entitled to receive shares of
QuadraMed Common Stock equal to each holder's pro rata portion of the total
amount of shares issued by QuadraMed as described in clauses (i) and (ii), based
on the total number of shares each holder elected to receive. See "THE STOCK
PURCHASE AGREEMENTS AND WARRANTS."
 
ELECTION FOR SHARES OR CASH
 
     Immediately prior to the Effective Time, each record holder of shares of
Medicus Common Stock will be entitled (i) to elect to receive cash for none,
some or all of such shares (a "Cash Election"), (ii) to elect to receive
QuadraMed Common Stock for none, some or all of such shares (a "Stock
Election"), or (iii) to indicate that such record holder has no preference as to
the receipt of cash or QuadraMed Common Stock for such shares (a
"Non-Election"). All such elections shall be made on a form designed for that
purpose (a "Form of Election"). Holders of record of shares of Medicus Common
Stock who hold such shares as nominees, trustees or in other representative
capacities (a "Representative") may submit multiple Forms of Election, provided
that such Representative certifies that each such Form of Election covers all
the shares of Medicus Common Stock held by each Representative for a particular
beneficial owner. All shares of Medicus Common Stock covered by Stock Elections
(the "Stock Election Shares") and all shares of Medicus Common Stock covered by
Non-Elections (the "Non-Election Shares") shall be converted into the right to
receive QuadraMed Common Stock (subject to QuadraMed's right to make the
QuadraMed Cash Election and QuadraMed's obligation to issue no more than
1,800,000 shares of QuadraMed Common Stock in the Merger), and the Cash Election
Shares shall be converted into the right to receive cash, without interest.
 
     Elections shall be made by holders of Medicus Common Stock by mailing or
otherwise delivering to the Exchange Agent a Form of Election. To be effective,
a Form of Election must be properly completed, signed and submitted to the
Exchange Agent. QuadraMed will have the discretion, which it may delegate in
whole or in part to the Exchange Agent, to determine whether Forms of Election
have been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Forms of Election. The decision of QuadraMed (or the
Exchange Agent) in such matters shall be conclusive and binding. Neither
QuadraMed nor the Exchange Agent will be under any obligation to notify any
person of any defect in a Form of Election submitted to the Exchange Agent. The
Exchange Agent shall also make all computations contemplated by the Merger
Agreement and all such computations shall be conclusive and binding on the
holders of Medicus Common Stock. A holder of Medicus Common Stock who does not
submit a Form of Election which is received by the Exchange Agent prior to the
Election Deadline shall be deemed to have made a Non-Election. If QuadraMed or
the Exchange Agent shall determine that any purported Cash Election or Stock
Election was not properly made, such purported Cash Election or Stock Election
shall be deemed to be of no force and effect and the stockholder making such
purported Cash Election or Stock Election shall be deemed to have made a
Non-Election. QuadraMed and Medicus shall each use its reasonable best efforts
to mail the Form of Election to all persons who become holders of Medicus Common
Stock during the period between the Medicus Record Date and 10:00 a.m.
California time, on the date seven calendar days prior to the anticipated
Effective Time and to make the Form of Election available to all persons who
become holders of Medicus Common Stock subsequent to such day and no later than
the close of business on the business day prior to the Effective Time. A Form of
Election must be received by the Exchange Agent prior to the Election Deadline
in order to be effective. All elections may be revoked until the Election
Deadline.

SURRENDER AND PAYMENT
 
     The First National Bank of Boston shall act as the Exchange Agent in the
Merger.
 
     Promptly after the Effective Time, QuadraMed shall make available to the
Exchange Agent (i) the shares of QuadraMed Common Stock issuable in exchange for
Stock Election Shares and Non-Election Shares and (ii) cash in an amount
sufficient to make payment with respect to Cash Election Shares and permit
payment of cash in lieu of fractional shares.
 
     Promptly after the Effective Time, the Surviving Corporation shall cause to
be mailed to each holder of record of the Certificate(s) which immediately prior
to the Effective Time represented outstanding shares of Medicus Common Stock,
whose shares were converted into the right to receive shares of QuadraMed Common
Stock (and cash in lieu of fractional shares) or the Per Share Cash Amount (i) a
letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon receipt of the
Certificates by the Exchange Agent, and shall be in such form and have such
other provisions as QuadraMed may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing shares of QuadraMed Common Stock (and cash in lieu of fractional
shares) or the Per Share Cash Amount. Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by QuadraMed, together with such letter of transmittal, duly completed
and validly executed in accordance with the instructions thereto, the holder of
such Certificate shall be entitled to receive in exchange therefor (i) a
certificate representing the number of whole shares of QuadraMed Common Stock
and payment in lieu of fractional shares which such holder has the right to
receive or (ii) the Per Share Cash Amount, as the case may be, and the
Certificate so surrendered shall be canceled. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented shares of
Medicus Common Stock will be deemed for all corporate purposes, other than the
payment of dividends, to evidence the ownership of the number of full shares of
QuadraMed Common Stock or the Per Share Cash Amount, as the case may be, into
which such shares of Medicus Common Stock shall have been so converted and the
right to receive an amount in cash in lieu of the issuance of any fractional
shares.
 
     No dividends or other distributions with respect to QuadraMed Common Stock
with a record date after the Effective Time will be paid to the holder of any
unsurrendered Certificate with respect to the shares of QuadraMed Common Stock
represented thereby until the holder of record of such Certificate shall
surrender such Certificate. Subject to applicable law, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of QuadraMed Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount
of any such dividends or other distributions with a record date after the
Effective Time payable with respect to such shares of QuadraMed Common Stock.
QuadraMed has never declared any cash dividends on the QuadraMed Common Stock.
QuadraMed currently intends to retain future earnings, if any, to fund the
development and growth of its business and does not anticipate paying any cash
dividends on the QuadraMed Common Stock in the foreseeable future. In addition,
QuadraMed's credit agreement contains provisions that restrict the payment of
dividends.
 
     If any certificate for shares of QuadraMed Common Stock is to be issued in
a name other than that in which the Certificate surrendered in exchange therefor
is registered, it will be a condition of the issuance thereof that the
Certificate so surrendered will be properly endorsed and otherwise in proper
form for transfer and that the person requesting such exchange will have paid to
QuadraMed or any agent designated by it any transfer or other taxes required by
reason of the issuance of a certificate for shares of QuadraMed Common Stock in
any name other than that of the registered holder of the Certificate
surrendered, or established to the satisfaction of QuadraMed or any agent of
QuadraMed that such tax has been paid or is not payable.
 
     In the event any Certificates shall have been lost, stolen or destroyed,
the Exchange Agent shall issue QuadraMed Common Stock (and cash in lieu of
fractional shares) in exchange for such lost, stolen or destroyed Certificates,
upon the making of an affidavit of that fact by the holder thereof. QuadraMed
may, in its discretion and as a condition precedent to the issuance of shares of
QuadraMed Common Stock, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably
 
                                       49

direct as indemnity against any claim that may be made against QuadraMed, the
Surviving Corporation or the Exchange Agent with respect to the Certificates
alleged to have been lost, stolen or destroyed.

the Merger Agreement, except pursuant to the Medicus 1997 Directors' Stock

COVENANTS
 
     Each of QuadraMed and Medicus will give the other access throughout the
period prior to the Effective Time, with regard to such party and its respective
subsidiaries, to its properties, books, contracts, commitments, records and
personnel. QuadraMed and Medicus have further agreed to prepare and file with
the Commission the Registration Statement of which this Proxy
Statement/Prospectus is a part, with respect to the QuadraMed Common Stock to be
issued in connection with the Merger and to make all necessary filings with
respect to the transactions contemplated by the Merger under applicable state
securities laws.
 
     QuadraMed has agreed to vote or cause to be voted all shares of Medicus
Common Stock owned by QuadraMed in favor of the Merger, which shares constitute
approximately 56.7% of the outstanding capital stock of Medicus.
 
     Medicus shall use its best efforts to deliver or cause to be delivered to
QuadraMed from those persons who may be deemed "Affiliates" of Medicus within
the meaning of Rule 144 promulgated under the Securities Act an executed
Affiliate Agreement.
 
     Each of QuadraMed and Medicus has agreed to use its reasonable best efforts
to effectuate the transactions contemplated by the Merger Agreement and to

EFFECT ON EMPLOYEE BENEFIT PLANS
 
     For purposes of QuadraMed employee benefit plans, Medicus employees will
receive full credit for years of service with Medicus.
 
NO SOLICITATION
 
     Medicus and its subsidiaries and the officers, directors, employees or
other agents of Medicus and its subsidiaries will not, directly or indirectly,
(i) take any action to solicit, initiate or encourage any Takeover Proposal (as
defined below) or (ii) subject to the terms of the immediately following
sentence, engage in negotiations with, or disclose any nonpublic information
relating to Medicus or any of its subsidiaries to, or afford access to the
properties, books or records of Medicus or any of its subsidiaries to, any
person that has advised Medicus that it may be considering making, or that has
made, a Takeover Proposal; provided, however, that nothing shall prohibit
Medicus' Board of Directors from taking and disclosing to Medicus' stockholders
a position with respect to a tender offer pursuant to Rules 14d-9 and 14e-2
promulgated under the Exchange Act. Notwithstanding the immediately preceding
sentence, if an unsolicited Takeover Proposal, or an unsolicited written
expression of interest that can reasonably be expected to lead to a Takeover
Proposal, shall be received by the Board of Directors of Medicus, then, to the
extent the Board of Directors of Medicus believes in good faith (after
consultation with its financial advisor) that such Takeover Proposal would, if
consummated, result in a transaction more favorable to Medicus' stockholders
from a financial point of view
 
                                       53
<PAGE>   68
 
than the Merger (any such more favorable Takeover Proposal being referred to as
a "Superior Proposal") and the Board of Directors of Medicus determines in good
faith after consultation with outside legal counsel that it is necessary for the
Board of Directors of Medicus to comply with its fiduciary duties to
stockholders under applicable law, Medicus and its officers, directors,
employees, investment bankers, financial advisors, attorneys, accountants and
other representatives retained by it may furnish in connection therewith
information and take such other actions as are consistent with the fiduciary
obligations of Medicus' Board of Directors, and such actions shall not be
considered a breach of the Merger Agreement, provided that in each such event
Medicus notifies QuadraMed of such determination by the Medicus Board of
Directors and provides QuadraMed with a true and complete copy of the Superior
Proposal received from such third party, if the Superior Proposal is in writing,
or a complete written summary thereof, if it is not in writing, and provides
QuadraMed with all documents containing or referring to non-public information
of Medicus that are supplied to such third party; provided further, that (A) the
Board of Directors of Medicus has determined, with the advice of Medicus'
investment bankers, that such third party is capable of making a Superior
Proposal upon satisfactory completion of such third party's review of the
information supplied by Medicus, (B) the third party has stated that it intends
to make a Superior Proposal, (C) Medicus may not provide any non-public
information to any such third party if it has not prior to the date thereof
provided such information to QuadraMed or QuadraMed's representatives, (D)
Medicus notifies QuadraMed in advance of any disclosure of non-public
information to any such third party, with a description of the information
proposed to be disclosed, and (E) Medicus provides such non-public information
pursuant to a non-disclosure agreement at least as restrictive as the existing
confidentiality agreement between QuadraMed and Medicus. Medicus will promptly
notify QuadraMed after receipt of any Takeover Proposal or any notice that any
person is considering making a Takeover Proposal or any request for non-public
information relating to Medicus or any of its subsidiaries or for access to the
properties, books or records of Medicus or any of its subsidiaries by any person
that has advised Medicus that it may be considering making, or that has made, a
Takeover Proposal and will keep QuadraMed fully informed of the status and
details of any such Takeover Proposal, notice, request, or any correspondence or
communications related thereto and shall provide QuadraMed with a true and
complete copy of such Takeover Proposal, notice, or request or correspondence or
communications related thereto, if it is in writing, or a complete written
summary thereof, if it is not in writing. A "Takeover Proposal" means any offer
or proposal for, or any indication of interest in, a merger or other business
combination involving Medicus or any of its subsidiaries or the acquisition of
any significant equity interest in, or a significant portion of the assets of,
Medicus or any of its subsidiaries, other than the transactions contemplated by
the Merger Agreement.
 
INDEMNIFICATION
 
     After the Effective Time, QuadraMed will, and will cause the Surviving
Corporation to, indemnify and hold harmless the present and former officers,
directors, employees and agents of Medicus (the "Indemnified Parties") in
respect of acts or omissions occurring on or prior to the Effective Time to the
extent permitted by law and to the extent provided under Medicus' Amended and
Restated Certificate of Incorporation and Bylaws or any indemnification
agreement with Medicus' officers and directors to which Medicus is a party, in
each case in effect on the date of the Merger Agreement. Such indemnification
shall be subject to any limitation imposed from time to time under applicable
law. Without limitation of the foregoing, in the event any such Indemnified
Party is or becomes involved in any capacity in any action, proceeding or
investigation in connection with any matter relating to the Merger Agreement or
the transactions contemplated thereby occurring on or prior to the Effective
Time, QuadraMed shall, or shall cause the Surviving Corporation to, pay as
incurred such Indemnified Party's reasonable legal and other expenses (including
the cost of any investigation and preparation) incurred in connection therewith
to the extent permitted by law and to the extent provided under Medicus' Amended
and Restated Certificate of Incorporation and Bylaws or the indemnification
agreement with such Indemnified Party.
 
     For two years after the Effective Time, QuadraMed will, or will cause the
Surviving Corporation to, use its best efforts to provide officers' and
directors' liability insurance in respect of acts or omissions occurring on or
prior to the Effective Time covering each such person currently covered by
Medicus' officers' and directors' liability insurance policy on terms
substantially similar to those of such policy in effect on the date hereof.
 
                                       54
<PAGE>   69
 
QuadraMed shall not be obligated to, or to cause the Surviving Corporation to,
pay premiums in excess of 150% of the amount per annum Medicus paid in its last
full fiscal year, and if the Surviving Corporation is unable to obtain the
required insurance, it shall obtain as much comparable insurance as possible for
an annual premium equal to such maximum amount.
 
     To the extent there is any claim, action, suit, proceeding or investigation
(whether arising before or after the Effective Time) against an Indemnified
Party that arises out of or pertains to any action or omission in his or her
capacity as a director, officer, employee, fiduciary or agent of Medicus
occurring prior to the Effective Time, or arises out of or pertains to the
transactions contemplated by the Merger Agreement for a period of two years
after the Effective Time (whether arising before or after the Effective Time),
such Indemnified Party shall be entitled to be represented by counsel and
following the Effective Time (i) any counsel retained by the Indemnified Parties
shall be reasonably satisfactory to the Surviving Corporation and QuadraMed,
(ii) the Surviving Corporation and QuadraMed shall pay the reasonable fees and
expenses of such counsel, promptly after statements therefor are received and
(iii) the Surviving Corporation and QuadraMed will cooperate in the defense of
any such matter. However, neither the Surviving Corporation nor QuadraMed shall
be liable for any settlement effected without its written consent (which consent
shall not be unreasonably withheld); and in the event that any claim or claims
for indemnification are asserted or made within such two-year period, all rights
to indemnification in respect of any such claim or claims shall continue until
the disposition of any and all such claims. The Indemnified Parties as a group
may retain only one law firm to represent them with respect to any single action
unless a conflict on any significant issue exists between the positions of any
two or more Indemnified Parties.
 
TERMINATION; EXPENSES; AMENDMENT; WAIVER
 
     At any time prior to the Effective Time, whether before or after approval
of the matters presented in connection with the Merger by the stockholders of
Medicus, the Merger Agreement may be terminated: (i) by mutual consent of
QuadraMed and Medicus; (ii) by either QuadraMed or Medicus, if, without fault of
the terminating party, the closing of the Merger shall not have occurred on or
before May 1, 1998 (or such later date as may be agreed upon in writing by the
parties); (iii) by QuadraMed, if Medicus shall breach any of its
representations, warranties or obligations under the Merger Agreement and such
breach shall not have been cured within ten business days of receipt by Medicus
of written notice of such breach or the Board of Directors of Medicus shall have
withdrawn or modified its recommendation of the Merger Agreement or the Merger
in a manner adverse to QuadraMed or shall have resolved to do any of the
foregoing; (iv) by Medicus, if QuadraMed shall breach any of its
representations, warranties or obligations under the Merger Agreement and such
breach shall not have been cured within ten days following receipt by QuadraMed
of written notice of such breach; or (v) by either QuadraMed or Medicus if any
permanent injunction or other order of a court or other competent authority
preventing the consummation of the Merger shall have become final and
nonappealable or if any required approval of the stockholders of Medicus shall
not have been obtained by reason of the failure to obtain the required vote upon
a vote held at a duly held meeting of stockholders or at any adjournment
thereof.
 
     Whether or not the Merger is consummated, all costs and expenses incurred
in connection with the Merger Agreement and the transactions contemplated
thereby (including, without limitation, the fees and expenses of its advisors,
accountants and legal counsel) shall be paid by the party incurring such
expenses, except that expenses incurred in connection with printing this Proxy
Statement/Prospectus and the Registration Statement, registration and filing
fees incurred in connection with this Proxy Statement/Prospectus and the
Registration Statement, the listing of additional shares with the Nasdaq
National Market, and fees, costs and expenses associated with compliance with
applicable state securities laws in connection with the Merger shall be paid by
QuadraMed.
 
     In the event that QuadraMed shall terminate the Merger Agreement because
(i) Medicus has breached any representation, warranty or obligation under the
Merger Agreement and such breach is not cured as described above, (ii) the
Medicus Board of Directors has withdrawn or modified its recommendation of the
Merger Agreement or the Merger in a manner adverse to QuadraMed or (iii) the
Medicus stockholders do not approve the Merger (but only if all of the Medicus

                    CERTAIN INFORMATION CONCERNING QUADRAMED
 
     QuadraMed Corporation, a Delaware corporation ("QuadraMed"), develops,
markets and sells software products and services designed to enable health care
providers and payors to increase operational efficiency, improve cash flow,
measure the cost of care and effectively administer managed care contracts.
QuadraMed's suite of products is an integrated offering of electronic data
interchange ("EDI"), financial management and decision support solutions for
both providers and payors. In addition, QuadraMed provides business office
outsourcing and cash flow management services.
 
     Electronic Data Interchange. These products enable the editing and
formatting of all claims submitted to payors to help ensure accuracy and
completeness, which results in more efficient reimbursement of third party
claims. QuadraMed collects and utilizes detailed clinical and financial
information from customers who license its EDI products. This data, which is
supplemented with similar, publicly-available information, forms the basis of
QuadraMed's proprietary databases for its decision support products.
 
     Financial Management Products. These products utilize the enhanced data
stream created by QuadraMed's EDI products to allow providers to track payor
contract terms and review medical billing information to ensure that bills are
properly coded and include all services rendered. These capabilities facilitate
a provider's ability to obtain timely and accurate reimbursement and to
administer and measure the profitability of managed care contracts. Further,
QuadraMed offers a product that is designed to improve the ability of health
care providers to prevent Medicare and Medicaid fraud and abuse by identifying
potentially fraudulent coding in their medical bills. In addition, QuadraMed's
electronic document imaging products allow its customers to improve work flow
and move toward a paperless office environment.
 
     Decision Support Products. These products include database analysis
software and national and regional benchmark data that enable customers to
perform clinical, financial and marketing analyses. These products utilize the
enhanced data stream created by QuadraMed's EDI and financial management
products to build proprietary databases that enable providers to measure more
accurately the resources consumed in the provision of care and to compare
clinical outcomes against the associated costs.
 
     Business Office Outsourcing and Cash Flow Management Services. These
services are offered to health care providers, many of which are recognizing the
value of outsourcing their business office operations to reduce costs, increase
cash flow and improve operating efficiencies. QuadraMed believes that it
possesses a significant advantage in the provision of outsourcing services due
to its ability to use its own QuanTIM(R) suite of software products and its
centralized cash flow management operations.
 
     QuadraMed's executive offices are located at 80 East Sir Francis Drake
Blvd., Suite 2A, Larkspur, California 94939 and its telephone number is (415)
461-7725.

                     CERTAIN INFORMATION CONCERNING MEDICUS
 
     Medicus develops, markets, and supports a family of specialized integrated
software products utilized by health care financial administrators, physicians
and nursing executives, health information and other administrative departments
to capture, structure and analyze clinical, operational and financial
information. Medicus' specialized software applications and services allow these
professionals to measure, monitor and manage organizational performance and
optimize outcomes. Medicus also provides product-related maintenance and support
services. Clients of Medicus include hospitals, academic medical centers,
managed care organizations, community care networks, integrated health systems,
primary care and multi-specialty physician groups, government agencies, and
other organizations.
 
     Medicus offers products and services in the following categories:
 
     Clinical Data Systems (CDS). DS is an integrated encoding system and data
repository that enables the health care provider to classify, capture, validate,
and analyze clinical data. This expert encoding system aids in optimizing
prospective payment reimbursement for both inpatient and ambulatory care
services. It captures and validates clinical indicators, severity and risk
factors as well as patient demographics data, diagnoses and procedures. By
validating data at the point of capture and linking it to a Diagnosis Related
Group, the CDS creates an accurate and complete data repository that provides
the information required to manage costs and improve clinical effectiveness and
service efficiency.
 
     Decision Support Systems. This division offers two lines of products,
Enterprise Analyst and Resource Case Management. Enterprise Analyst is a fully
integrated, enterprise wide decision support system application designed to
allow Medicus' customers to maximize the principal components of value: quality,
outcomes and cost containment. Resource Case Management provides case managers
and other personnel the ability to evaluate and manage patient care resources on
a daily basis.
 
     Patient Focused System. This division's main product is InterAct 2000,
which is a modular system of software tools and methodologies designed to manage
patient care resource utilization through workload measurement, staffing against
budget, cost and productivity reporting and employer scheduling. InterAct 2000
includes two integrated modules, the Workload/Productivity module which uses an
organization's own financial and quality of care objectives to generate
assessments of workload and staffing needs against the department's resource
utilization budget, and the Personnel/Scheduler module which creates balanced
staff schedules based on a specific scheduling algorithm and a set of user
defined rules.
 
     Maintenance and Support Services. Medicus provides training and support
services during client implementation and thereafter, as required. Maintenance
and support services include software updates, enhancements and services which
are purchased by substantially all of Medicus' clients under renewable annual
contracts. Medicus maintains logging, notification, and follow-up procedures to
track client problems encountered in implementing and operating its products.
Medicus also conducts client conferences to exchange ideas regarding product
usage and product extensions. Management believes that these conferences are
valuable in gathering ideas for future products as well as enhancements to
Medicus' current product line.
 
     Medicus' executive offices are located at One Rotary Center, Suite 1111,
Evanston, Illinois, 60201 and its telephone number is (847) 570-7500.

                        COMPARISON OF STOCKHOLDER RIGHTS
 
     The following is a summary of material differences between the rights of
holders of QuadraMed Common Stock and the rights of holders of Medicus Common
Stock.
 
     Each of QuadraMed and Medicus is organized under the laws of the State of
Delaware. Any material differences in the rights of their respective
stockholders would arise from various provisions of the Certificate of
Incorporation and Bylaws of each of QuadraMed and Medicus. Among the differences
between the rights of the holders of QuadraMed and Medicus are the following:
 
     Capital Stock. The total number of authorized shares of capital stock of
QuadraMed is 25,000,000 shares, consisting of 20,000,000 shares of Common Stock
with a par value of $.01 per share and 5,000,000 shares of Preferred Stock with
a par value of $.01 per share, while the total number of authorized shares of
capital stock of Medicus is 11,000,500 shares, consisting of 10,000,000 shares
of Common Stock with a par value of $.01 per share, 1,000,000 shares of
Preferred Stock with a par value of $.01 per share and 500 shares of Voting
Preferred Stock with a par value of $1,000 per share.
 
     Special Meetings of Stockholders. The Bylaws of QuadraMed provide that a
special meeting of the stockholders may be called only (i) by the Chairman of
the Board of Directors, (ii) by the Chairman or the Secretary at the written
request of a majority of the total number of Directors which the Corporation
would have if there were no vacancies, or (iii) by the holders of shares
entitled to cast not less than 10 percent of the votes at such special meeting,
while the Bylaws of Medicus provide that a Special Meeting may be called by the
President and shall be called by the President or Secretary at the request in
writing of a majority of the whole board of directors, or at the request in
writing of stockholders owning a majority of the capital stock of the
corporation outstanding and entitled to vote.
 
     Annual Meetings of Stockholders. The Bylaws of QuadraMed provide that to
propose business to be transacted at an annual meeting, a stockholder's notice
must be received by QuadraMed not later than the close of business on the 60th
day nor earlier than the close of business on the 90th day prior to the first
anniversary of the preceding year's annual meeting; provided, however, that in
the event that no annual meeting was held in the previous year or the date of
the annual meeting has been changed by more than 30 days from the date
contemplated at the time of the previous year's proxy statement, notice by the
stockholder to be timely must be so received no earlier than the close of
business on the 90th day prior to such annual meeting and not later than the
close of business on the later of the 60th day prior to such annual meeting or,
in the event public announcement of the date of such annual meeting is first
made by QuadraMed fewer than 70 days prior to the date of such annual meeting,
the close of business on the 10th day following the day on which public
announcement of the date of such meeting is first mailed by QuadraMed. The
Bylaws of Medicus contain no such provision.
 
     Classification of Directors. QuadraMed's Certificate provides for the
classification of the QuadraMed Board of Directors into three classes as nearly
equal in number as possible, with one class being elected at each annual meeting
to a three year term. Neither the Medicus Certificate nor the Medicus Bylaws
provides for such classification of directors.
 
     Removal of Directors. QuadraMed's Certificate provides that directors may
be removed by the affirmative vote of the holders of at least 66 2/3% of the
combined voting power of all shares of the Corporation entitled to vote
generally in the election of directors, voting together as a single class. The
Bylaws of Medicus contain no such provision.
 
     Voting Rights. QuadraMed's Certificate provides that any Business
Combination (as defined therein) involving QuadraMed and an Interested
Stockholder (as defined therein) must be approved by the affirmative vote of at
least 66 2/3% of the combined voting power of all shares of QuadraMed entitled
to vote generally in the election of directors, voting together as a single
class. Such affirmative vote shall be required notwithstanding the fact that no
vote may be required, or that some lesser percentage may be specified, by law or
in any agreement with any national securities exchange or otherwise. As defined
in QuadraMed's Certificate, a "Business Combination" includes, among other
things: (i) any merger or consolidation of QuadraMed or any QuadraMed subsidiary
with any Interested Stockholder or affiliate or associate thereof; (ii) the
sale, lease,
 
                                       62
<PAGE>   77
 
exchange, mortgage, pledge, transfer or other disposition to, or with, any
Interested Stockholder or affiliate or associate thereof, of any assets of
QuadraMed or any QuadraMed subsidiary constituting not less than five percent of
the total assets of QuadraMed, as reported in the consolidated balance sheet of
QuadraMed as of the end of the most recent quarter with respect to which such
balance sheet has been prepared; (iii) the issuance or transfer by QuadraMed or
any QuadraMed subsidiary of any securities of QuadraMed or any QuadraMed
subsidiary to any Interested Stockholder or affiliate or associate thereof in
exchange for cash, securities or property together constituting not less than
five percent of the total assets of QuadraMed, as reported in the consolidated
balance sheet of QuadraMed as of the end of the most recent quarter with respect
to which such balance sheet has been prepared; (iv) the adoption of any plan or
proposal for the liquidation or dissolution of QuadraMed or any QuadraMed
subsidiary with any Interested Stockholder or affiliate or associate thereof;
and (v) any reclassification of securities or recapitalization of QuadraMed, or
any merger or consolidation of QuadraMed with any of its subsidiaries or any
similar transaction which has the effect, directly or indirectly, of increasing
the percentage of the outstanding shares of (a) any class of equity securities
of QuadraMed or any QuadraMed subsidiary or (b) any class of securities of
QuadraMed or any QuadraMed subsidiary convertible into equity securities of
QuadraMed or any QuadraMed subsidiary, represented by securities of such class
which are directly or indirectly owned by any Interested Stockholder or any
affiliate or associate thereof and "Interested Stockholder" means any person
(other than QuadraMed or any QuadraMed subsidiary) who or which, as of the
record date for the determination of stockholders entitled to notice of and to
vote on such Business Combination, or immediately prior to the consummation of
any such transaction (i) is or was, at any time within two years prior thereto,
the beneficial owner, directly or indirectly, of 15% or more of the then
outstanding Voting Shares, or (ii) is an "Affiliate" or "Associate" of QuadraMed
and at any time within two years prior thereto was the beneficial owner,
directly or indirectly, of 15% or more of the then outstanding "Voting Shares,"
or (iii) is an assignee of or has otherwise succeeded to any shares of capital
stock of QuadraMed which were at any time within two years prior thereto
beneficially owned by an Interested Stockholder, if such assignment or
succession shall have occurred in the course of a transaction, or series of
transactions, not involving a public offering within the meaning of the
Securities Act of 1933, as amended.
 
     Neither the Medicus Certificate nor the Bylaws of Medicus contain any
similar provision or provisions.

                              CERTAIN TRANSACTIONS

     John H. Austin, M.D., a director of QuadraMed, is the chief executive
officer of a limited partner of RHP. In connection with the approval of the RHP
Mergers by the QuadraMed board of directors, Dr. Austin disclosed this interest
and abstained from voting. See "Summary -- Recent Developments."

                              DIVIDEND INFORMATION
 
     QuadraMed has never declared any cash dividends on the QuadraMed Common
Stock. QuadraMed currently intends to retain future earnings, if any, to fund
the development and growth of its business and does not anticipate paying any
cash dividends on the QuadraMed Common Stock in the foreseeable future. In
addition, QuadraMed's credit agreement contains provisions that restrict the
payment of dividends.
 
     Medicus' predecessor, Managed Care Solutions, Inc. (prior to March 1, 1996)
and Medicus (beginning March 1, 1996) declared quarterly dividends of $0.03 per
share in each of the quarters in fiscal years 1995 and 1996. Medicus has not
declared any dividends since the end of its 1996 fiscal year, and the Board of
Directors of Medicus has determined not to pay dividends on the Medicus Common
Stock for the foreseeable future. In addition, Medicus' credit agreement
prohibits the declaration or payment of dividends on the Medicus Common Stock.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of November 9, 1997, by and among QuadraMed Corporation, a
Delaware corporation ("QuadraMed"), and Medicus Systems Corporation, a Delaware
corporation ("Medicus").
 
                                    RECITALS
 
     A. The Boards of Directors of Medicus and QuadraMed believe it is in the
best interests of their respective companies and the stockholders of their
respective companies that Medicus and a wholly owned subsidiary of QuadraMed to
be formed for the purposes hereof ("Merger Sub") combine into a single company
through the statutory merger of Merger Sub with and into Medicus (the "Merger")
and, in furtherance thereof, have approved the Merger.
 
     B. Pursuant to the Merger, among other things, the outstanding shares of
Medicus Common Stock, $.01 par value ("Medicus Common Stock"), shall be
converted into shares of QuadraMed Common Stock, $.01 par value ("QuadraMed
Common Stock"), or cash, or a combination thereof, on the terms set forth
herein.
 
     C. Medicus and QuadraMed desire to make certain representations and
warranties and other agreements in connection with the Merger.
 
     D. Concurrent with the execution of this Agreement and as an inducement to
QuadraMed to enter into this Agreement, certain of the stockholders of Medicus
who in the aggregate beneficially own in excess of 50% of the outstanding Common
Stock of Medicus have on the date hereof entered into stock purchase agreements
(the "Stock Purchase Agreements") to sell the shares of Medicus' Common Stock
owned by such person in exchange for a cash payment and a warrant to purchase
QuadraMed Common Stock (the "Warrants").
 
     NOW, THEREFORE, in consideration of the covenants and representations set
forth herein, and for other good and valuable consideration, the parties agree
as follows:
 
                                   ARTICLE I
 
                                   THE MERGER
 
     1.1  The Merger. At the Effective Time (as defined in Section 1.2) and
subject to and upon the terms and conditions of this Agreement, a Certificate of
Merger to be filed in respect of the Merger (the "Certificate of Merger") and
the applicable provisions of the Delaware General Corporation Law ("DGCL"),
Merger Sub shall be merged with and into Medicus, the separate corporate
existence of Merger Sub shall cease and Medicus shall continue as the surviving
corporation. Medicus as the surviving corporation after the Merger is
hereinafter sometimes referred to as the "Surviving Corporation."
 
     1.2  Closing; Effective Time. The closing of the transactions contemplated
hereby (the "Closing") shall take place as soon as practicable after the
satisfaction or waiver of each of the conditions set forth in Article VI hereof
or at such other time as the parties hereto agree (the "Closing Date"). The
Closing shall take place at the offices of Brobeck, Phleger & Harrison LLP, One
Market, Spear Street Tower, San Francisco, California 94105, or at such other
location as the parties hereto agree. In connection with the Closing, the
parties hereto shall cause the Merger to be consummated by filing the
Certificate of Merger with the Secretary of State of the State of Delaware and
with the Recorder of the County in which the registered office of each of
Medicus and Merger Sub is located, in accordance with the relevant provisions of
the DGCL (the time of such filing being the "Effective Time").
 
     1.3  Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of the DGCL. Without limiting the
 
                                       A-1
<PAGE>   80
 
generality of the foregoing, and subject thereto, at the Effective Time, all the
property, rights, privileges, powers and franchises of Medicus and Merger Sub
shall vest in the Surviving Corporation, and all debts, liabilities and duties
of Medicus and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.
 
     1.4  Certificate of Incorporation; Bylaws.
 
     (a) At the Effective Time, the Certificate of Incorporation of Merger Sub,
as in effect immediately prior to the Effective Time, shall be the Certificate
of Incorporation of the Surviving Corporation until thereafter amended as
provided by the DGCL and such Certificate of Incorporation.
 
     (b) The Bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.
 
     1.5  Directors and Officers. At the Effective Time, the directors and
officers of Merger Sub shall become the directors and officers of the Surviving
Corporation, until their respective successors are duly elected or appointed and
qualified.
 
     1.6  Effect on Capital Stock. By virtue of the Merger and without any
action on the part of Merger Sub, Medicus or the holders of any of the following
securities, subject to the provisions of this Section 1.6:
 
          (a) Conversion of Medicus Common Stock. At the Effective Time, each
     share of Medicus Common Stock issued and outstanding immediately prior to
     the Effective Time (other than any shares of Medicus Common Stock to be
     canceled pursuant to Section 1.6(b)) will be canceled and extinguished and
     be converted automatically into (i) the right to receive $7.50 in cash,
     without interest (the "Per Share Cash Amount"); or (ii) the right to
     receive 0.3125 shares of QuadraMed Common Stock (the "Exchange Ratio");
     provided, however, that (1) if the QuadraMed Stock Value (as defined below)
     exceeds $27.60, then the Exchange Ratio shall be the quotient obtained by
     dividing (A) $8.625 by (B) the QuadraMed Stock Value, and (2) if the
     QuadraMed Stock Value is less than $24.00, then the Exchange Ratio shall be
     the quotient obtained by dividing (A) $7.50 by (B) the QuadraMed Stock
     Value; provided further, however, that if the QuadraMed Stock Value is less
     than $20.40, then QuadraMed may, at its sole discretion, elect to have all
     or any portion of the shares of Medicus Common Stock converted into the Per
     Share Cash Amount (the "QuadraMed Cash Election"); or (iii) the right to
     receive a combination of shares of QuadraMed Common Stock and cash, all in
     accordance with the provisions of this Section 1.6. In the event of the
     QuadraMed Cash Election in which less than all of the outstanding shares of
     Medicus Common Stock will be converted into cash, the shares of Medicus
     Common Stock to be converted into cash as a result of the QuadraMed Cash
     Election will be selected pro rata according to the number of shares with
     respect to which a Stock Election (as defined below) has been made. The
     amounts paid in the Merger in exchange for shares of Medicus Common Stock
     shall be referred to herein as the "Merger Consideration." For purposes
     hereof, the "QuadraMed Stock Value" shall be equal to the average of the
     closing prices of QuadraMed Common Stock during the fifteen (15) days prior
     to the second day prior to the date of the Medicus Stockholders Meeting (as
     defined in Section 2.23).
 
          (b) Cancellation of Medicus Common Stock Owned by QuadraMed or
     Medicus. At the Effective Time, all shares of Medicus Common Stock that are
     owned by Medicus as treasury stock and each share of Medicus Common Stock
     owned by QuadraMed or any direct or indirect wholly owned subsidiary of
     QuadraMed or of Medicus immediately prior to the Effective Time shall be
     canceled and extinguished without any conversion thereof.
 
          (c) Medicus Stock Option Plans. At the Effective Time, the Medicus
     1989 Stock Option Plan, the Medicus 1991 Stock Option Plan, the Medicus
     1993 Stock Option Plan, the Medicus 1993 Performance Stock Option Plan, the
     Medicus 1994 Stock Option Plan, the Medicus 1994 Directors' Stock Option
     Plan, the Medicus 1995 RCM Stock Option Plan, the Medicus 1996 C.E.O. Stock
     Option Plan, the Medicus 1996 C.E.O. Replacement Stock Option Plan, the
     Medicus 1996 C.E.O. Special Stock Option Plan, the Medicus 1997 Employee
     Stock Option and Restricted Stock Plan, the Medicus 1997 Directors' Stock
     Option Plan (collectively, the "Medicus Stock Option Plans"), the Stock
     Exchange and Subscription warrants dated March 19, 1997 issued by Medicus
     to Richard C. Jelinek and a trust for his
 
                                       A-2
<PAGE>   81
 
     benefit (the "Jelinek Warrants") and the Stock Subscription Warrant dated
     March 1, 1996 issued by Medicus to TriHealth, Inc. (the "TriHealth
     Warrant") and all options or rights to purchase Medicus Common Stock then
     outstanding under the Medicus Stock Option Plans, the Jelinek Warrants and
     the TriHealth Warrant shall be assumed by QuadraMed in accordance with
     Section 5.11.
 
          (d) Capital Stock of Merger Sub. At the Effective Time, each share of
     Common Stock, $.01 par value, of Merger Sub ("Merger Sub Common Stock")
     issued and outstanding immediately prior to the Effective Time shall be
     converted into and exchanged for one validly issued, fully paid and
     nonassessable share of Common Stock, $.01 par value, of the Surviving
     Corporation. Each stock certificate of Merger Sub evidencing ownership of
     any such shares shall continue to evidence ownership of such shares of
     capital stock of the Surviving Corporation.
 
          (e) Adjustments to Exchange Ratio and Per Share Cash Amount. The
     Exchange Ratio and the Per Share Cash Amount shall be adjusted to reflect
     fully the effect of any stock split, reverse split, stock dividend
     (including any dividend or distribution of securities convertible into
     QuadraMed Common Stock or Medicus Common Stock), reorganization,
     recapitalization or other like change with respect to QuadraMed Common
     Stock or Medicus Common Stock occurring after the date hereof and prior to
     the Effective Time.
 
          (f) Fractional Shares. No fraction of a share of QuadraMed Common
     Stock will be issued in the Merger. In lieu of any fractional shares that
     would otherwise be issuable in the Merger in exchange for shares of Medicus
     Common Stock, QuadraMed shall pay the proportionate amount of the Per Share
     Cash Amount that would be payable in respect of such fractional share.
 
          (g) Limitation on Shares Issuable. In no event shall the aggregate
     number of shares of QuadraMed Common Stock which QuadraMed is obligated to
     issue (1) upon the exercise of Warrants and (2) in exchange for outstanding
     shares of Medicus Common Stock pursuant to this Agreement exceed a total of
     1,800,000 shares. In the event that the aggregate number of shares of
     Common Stock that holders of Warrants and holders of Medicus Common Stock
     have elected to receive as described in clauses (1) and (2) in the
     immediately preceding sentence exceeds 1,800,000 shares, QuadraMed shall
     only be required to issue 1,800,000 shares of QuadraMed Common Stock and
     such holders shall be entitled to receive shares of QuadraMed Common Stock
     equal to each holder's pro rata portion of the total amount of shares
     issued by QuadraMed as described in clauses (1) and (2), based on the total
     number of shares each holder and each elected to receive.
 
          (h) Election for Shares or Cash. Each record holder immediately prior
     to the Effective Time of shares of Medicus Common Stock will be entitled
     (i) to elect to receive cash for none, some or all of such shares (a "Cash
     Election"), (ii) to elect to receive QuadraMed Common Stock for none, some
     or all of such shares (a "Stock Election"), or (iii) to indicate that such
     record holder has no preference as to the receipt of cash or QuadraMed
     Common Stock for such shares (a "Non-Election"). All such elections shall
     be made on a form designed for that purpose (a "Form of Election"). Holders
     of record of shares of Medicus Common Stock who hold such shares as
     nominees, trustees or in other representative capacities (a
     "Representative") may submit multiple Forms of Election, provided that such
     Representative certifies that each such Form of Election covers all the
     shares of Medicus Common Stock held by each Representative for a particular
     beneficial owner. All shares of Medicus Common Stock covered by Stock
     Elections (the "Stock Election Shares") and all shares of Medicus Common
     Stock covered by Non-Elections (the "Non-Election Shares") shall be
     converted into the right to receive QuadraMed Common Stock, and the Cash
     Election Shares shall be converted into the right to receive cash, without
     interest.
 
          (i) Election Procedures. Elections shall be made by holders of Medicus
     Common Stock by mailing or otherwise delivering to the Exchange Agent (as
     defined in Section 1.7) a Form of Election. To be effective, a Form of
     Election must be properly completed, signed and submitted to the Exchange
     Agent and accompanied by the certificates representing the shares of
     Medicus Common Stock as to which the election is being made (or by an
     appropriate trust company in the United States or a member of a registered
     national securities exchange or the National Association of Securities
     Dealers, Inc. (the
 
                                       A-3
<PAGE>   82
 
     "NASD")). QuadraMed will have the discretion which it may delegate in whole
     or in part to the Exchange Agent, to determine whether Forms of Election
     have been properly completed, signed and submitted or revoked and to
     disregard immaterial defects in Forms of Election. The decision of
     QuadraMed (or the Exchange Agent) in such matters shall be conclusive and
     binding. Neither QuadraMed nor the Exchange Agent will be under any
     obligation to notify any person of any defect in a Form of Election
     submitted to the Exchange Agent. The Exchange Agent shall also make all
     computations contemplated by this Section 1.6 and all such computations
     shall be conclusive and binding on the holders of Medicus Common Stock. For
     the purposes hereof, a holder of Medicus Common Stock who does not submit a
     Form of Election which is received by the Exchange Agent prior to the
     Election Deadline (as hereinafter defined) shall be deemed to have made a
     Non-Election. If QuadraMed or the Exchange Agent shall determine that any
     purported Cash Election or Stock Election was not properly made, such
     purported Cash Election or Stock Election shall be deemed to be of no force
     and effect and the stockholder making such purported Cash Election or Stock
     Election shall for purposes hereof, be deemed to have made a Non-Election.
     QuadraMed and Medicus shall each use its reasonable best efforts to mail
     the Form of Election to all persons who become holders of Medicus Common
     Stock during the period between the record date for the Medicus
     Stockholders Meeting (as defined in Section 2.23) and 10:00 a.m. California
     time, on the date seven calendar days prior to the anticipated Effective
     Time and to make the Form of Election available to all persons who become
     holders of Medicus Common Stock subsequent to such day and no later than
     the close of business on the business day prior to the Effective Time. A
     Form of Election must be received by the Exchange Agent by the close of
     business on the last business day prior to the Effective Time (the
     "Election Deadline") in order to be effective. All elections may be revoked
     until the Election Deadline.
 
     1.7  Surrender of Certificates.
 
     (a) Exchange Agent. The First National Bank of Boston shall act as exchange
agent (the "Exchange Agent") in the Merger.
 
     (b) QuadraMed to Provide Common Stock and Cash. Promptly after the
Effective Time, QuadraMed shall make available to the Exchange Agent for
exchange in accordance with this Article I, through such reasonable procedures
as QuadraMed may adopt, (i) the shares of QuadraMed Common Stock issuable in
exchange for Stock Election Shares and Non-Election Shares and (ii) cash in an
amount sufficient to purchase Cash Election Shares and permit payment of cash in
lieu of fractional shares pursuant to Section 1.6(f).
 
     (c) Exchange Procedures. Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each holder of record of a certificate
or certificates (the "Certificates") which immediately prior to the Effective
Time represented outstanding shares of Medicus Common Stock, whose shares were
converted into the right to receive shares of QuadraMed Common Stock (and cash
in lieu of fractional shares) pursuant to Section 1.6, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon receipt of the
Certificates by the Exchange Agent, and shall be in such form and have such
other provisions as QuadraMed may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for certificates
representing shares of QuadraMed Common Stock (and cash in lieu of fractional
shares) or cash. Upon surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as may be appointed by
QuadraMed, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to receive in exchange therefor (i) a certificate
representing the number of whole shares of QuadraMed Common Stock and payment in
lieu of fractional shares which such holder has the right to receive pursuant to
Section 1.6 or (ii) cash, as the case may be, and the Certificate so surrendered
shall forthwith be canceled. Until so surrendered, each outstanding Certificate
that, prior to the Effective Time, represented shares of Medicus Common Stock
will be deemed for all corporate purposes, other than the payment of dividends,
to evidence the ownership of the number of full shares of QuadraMed Common Stock
or cash, as the case may be, into which such shares of Medicus Common Stock
shall have been so converted and the right to receive an amount in cash in lieu
of the issuance of any fractional shares in accordance with Section 1.6.
 
                                       A-4
<PAGE>   83
 
     (d) Distributions With Respect to Unexchanged Shares. No dividends or other
distributions with respect to QuadraMed Common Stock with a record date after
the Effective Time will be paid to the holder of any unsurrendered Certificate
with respect to the shares of QuadraMed Common Stock represented thereby until
the holder of record of such Certificate shall surrender such Certificate.
Subject to applicable law, following surrender of any such Certificate, there
shall be paid to the record holder of the certificates representing whole shares
of QuadraMed Common Stock issued in exchange therefor, without interest, at the
time of such surrender, the amount of any such dividends or other distributions
with a record date after the Effective Time theretofore payable (but for the
provisions of this Section 1.7(d)) with respect to such shares of QuadraMed
Common Stock.
 
     (e) Transfers of Ownership. If any certificate for shares of QuadraMed
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to QuadraMed or any agent designated by it any transfer
or other taxes required by reason of the issuance of a certificate for shares of
QuadraMed Common Stock in any name other than that of the registered holder of
the Certificate surrendered, or established to the satisfaction of QuadraMed or
any agent of QuadraMed. Notwithstanding anything to the contrary in this Section
1.7, none of the Exchange Agent, the Surviving Corporation or any party hereto
shall be liable to any person for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.
 
     1.8  No Further Ownership Rights in Medicus Common Stock. All shares of
QuadraMed Common Stock issued upon the surrender for exchange of shares of
Medicus Common Stock in accordance with the terms hereof (including any cash
paid in lieu of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Medicus Common Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Medicus Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article I.
 
     1.9  Lost, Stolen or Destroyed Certificates. In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue
QuadraMed Common Stock in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof, such shares of QuadraMed Common Stock (and cash in lieu of fractional
shares) as may be required pursuant to Section 1.6; provided, however, that
QuadraMed may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed Certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against QuadraMed, the Surviving Corporation or the
Exchange Agent with respect to the Certificates alleged to have been lost,
stolen or destroyed.
 
     1.10  Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Medicus and Merger Sub, the officers and directors of Medicus
and Merger Sub are fully authorized in the name of their respective corporations
or otherwise to take, and will take, all such lawful and necessary action, so
long as such action is not inconsistent with this Agreement.
 
     1.11  Dissenting Shares. Notwithstanding any other provisions of this
Agreement to the contrary, shares of Medicus QuadraMed Common Stock that are
outstanding immediately prior to the Effective Time and which are held by
stockholders who shall have demanded properly in writing appraisal for such
shares in accordance with Section 262 of the DGCL (collectively, the "Dissenting
Shares") shall not be converted into or represent the right to receive the
Merger Consideration. Such stockholders shall be entitled to receive payment of
the appraised value of such shares of Medicus Common Stock held by them in
accordance with the provisions of Section 262, except that all Dissenting Shares
held by stockholders who shall have failed to perfect or who effectively shall
have withdrawn or lost their rights to appraisal of such shares of Medicus
 
                                       A-5
<PAGE>   84
 
Common Stock under such Section 262 shall thereupon be deemed to have been
converted into and to have become exchangeable, as of the Effective Time, for
the right to receive, without any interest thereon, shares of QuadraMed Common
Stock based on the Exchange Ratio determined in accordance with Section 1.1
hereof, as if such shares were covered by Non-Elections, upon surrender, in the
manner provided in this Article I, of the certificate or certificates that
formerly evidenced such shares of Medicus Common Stock.
 
                                   ARTICLE II
 
                   REPRESENTATIONS AND WARRANTIES OF MEDICUS
 
     In this Agreement, any reference to any event, change, condition or effect
being "material" with respect to any entity or group of entities means any
material event, change, condition or effect related to the condition (financial
or otherwise), properties, assets (including intangible assets), liabilities,
business, operations or results of operations of such entity or group of
entities. In this Agreement, any reference to a "Material Adverse Effect" with
respect to any entity or group of entities means any event, change or effect
that is materially adverse to the condition (financial or otherwise),
properties, assets, liabilities, business, operations or results of operations
of such entity and its subsidiaries, taken as a whole.
 
     Except as disclosed in a document of even date herewith and delivered by
Medicus to QuadraMed prior to the execution and delivery of this Agreement and
referring to the representations and warranties in this Agreement (the "Medicus
Disclosure Schedule"), Medicus represents and warrants to QuadraMed and Merger
Sub as follows:
 
     2.1  Organization, Standing and Power. Each of Medicus and its subsidiaries
is a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization. Each of Medicus and its subsidiaries
has the corporate power to own its properties and to carry on its business as
now being conducted and as proposed to be conducted and is duly qualified to do
business and is in good standing in each jurisdiction in which the failure to be
so qualified and in good standing would have a Material Adverse Effect on
Medicus. Medicus has delivered a true and correct copy of the Amended and
Restated Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), and Bylaws, as amended, or other charter documents, as
applicable, of Medicus and each of its subsidiaries, each as amended to date, to
QuadraMed. Neither Medicus nor any of its subsidiaries is in violation of any of
the provisions of its Certificate of Incorporation or Bylaws or equivalent
organizational documents. Medicus is the owner of all outstanding shares of
capital stock of each of its subsidiaries and all such shares are duly
authorized, validly issued, fully paid and nonassessable. All of the outstanding
shares of capital stock of each such subsidiary are owned by Medicus free and
clear of all liens, charges, claims or encumbrances or rights of others. There
are no outstanding subscriptions, options, warrants, puts, calls, rights,
exchangeable or convertible securities or other commitments or agreements of any
character relating to the issued or unissued capital stock or other securities
of any such subsidiary, or otherwise obligating Medicus or any such subsidiary
to issue, transfer, sell, purchase, redeem or otherwise acquire any such
securities. Except as disclosed in the Medicus SEC Documents (as defined in
Section 2.4), Medicus does not directly or indirectly own any equity or similar
interest in, or any interest convertible or exchangeable or exercisable for, any
equity or similar interest in, any corporation, partnership, joint venture or
other business association or entity.
 
     2.2  Capital Structure. The authorized capital stock of Medicus consists of
10,000,000 shares of Common Stock, $.01 par value, 1,000,000 shares of Preferred
Stock, $.01 par value, and 500 shares of Voting Preferred Stock, $1,000 par
value, of which there were issued and outstanding as of the close of business on
November 7, 1997, 5,487,971 shares of Common Stock and no shares of Preferred
Stock or Voting Preferred Stock. There are no other outstanding shares of
capital stock or voting securities and no outstanding commitments to issue any
shares of capital stock or voting securities other than pursuant to the exercise
of options outstanding as of such date under the Medicus Stock Option Plans and
the obligation to issue 34,800 restricted shares previously granted under the
Medicus Stock Option Plans. All outstanding shares of Medicus Common Stock are
duly authorized, validly issued, fully paid and non-assessable and are free of
any liens or encumbrances created by, or resulting from the actions of, Medicus,
and are not subject to preemptive rights or rights of first refusal created by
statute, the Certificate of Incorporation or Bylaws of Medicus or any
 
                                       A-6
<PAGE>   85
 
agreement to which Medicus is a party or by which it is bound. As of the close
of business on November 7, 1997, Medicus has 1,501,350 shares subject to
outstanding, unexercised options. Since November 7, 1997, Medicus has not issued
or granted additional options under the Medicus Stock Option Plans. Except for
(i) the rights created pursuant to this Agreement or the Medicus Stock Option
Plans and (ii) Medicus' right to repurchase any unvested shares under the
Medicus Stock Option Plans, there are no other options, warrants, calls, rights,
commitments or agreements of any character to which Medicus is a party or by
which it is bound obligating Medicus to issue, deliver, sell, repurchase or
redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
shares of capital stock of Medicus or obligating Medicus to grant, extend,
accelerate the vesting of, change the price of, or otherwise amend or enter into
any such option, warrant, call, right, commitment or agreement. There are no
contracts, commitments or agreements relating to voting, purchase or sale of
Medicus' capital stock (i) between or among Medicus and any of its stockholders
and (ii) to the best of Medicus' knowledge, between or among any of Medicus'
stockholders. The terms of the Medicus Stock Option Plans permit the assumption
or substitution of options to purchase QuadraMed Common Stock as provided in
this Agreement, without the consent or approval of the holders of such
securities, the Medicus stockholders, or otherwise and without any acceleration
of the exercise schedule or vesting provisions in effect for those options. True
and complete copies of all forms of agreements and instruments relating to or
issued under the Medicus Stock Option Plans have been made available to
QuadraMed and such agreements and instruments have not been amended, modified or
supplemented, and there are no agreements to amend, modify or supplement such
agreements or instruments in any case from the form made available to QuadraMed.
 
     2.3  Authority. Medicus has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Medicus, subject only to the approval of the
Merger by Medicus' stockholders as contemplated by Section 6.1(a). This
Agreement has been duly executed and delivered by Medicus and constitutes the
valid and binding obligation of Medicus enforceable against Medicus in
accordance with its terms. The execution and delivery of this Agreement by
Medicus does not, and the consummation of the transactions contemplated hereby
will not, conflict with, or result in any violation of, or default under (with
or without notice or lapse of time, or both), or give rise to a right of
termination, cancellation or acceleration of any obligation or loss of any
benefit under (i) any provision of the Certificate of Incorporation or Bylaws of
Medicus or any of its subsidiaries, as amended, or (ii) any material mortgage,
indenture, lease, contract or other agreement or instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to Medicus or any of its subsidiaries or any of their
properties or assets, except where such conflict, violation, default,
termination, cancellation or acceleration with respect to the foregoing
provisions of (ii) would not have had and would not reasonably be expected to
have a Material Adverse Effect on Medicus. No consent, approval, order or
authorization of, or registration, declaration or filing with, any court,
administrative agency or commission or other governmental authority or
instrumentality ("Governmental Entity") is required by or with respect to
Medicus or any of its subsidiaries in connection with the execution and delivery
of this Agreement or the consummation of the transactions contemplated hereby
and thereby, except for (i) the filing of the Certificate of Merger as provided
in Section 1.2, (ii) the filing with the Securities and Exchange Commission (the
"SEC") and the NASD of the Proxy Statement (as defined in Section 2.23) relating
to the Medicus Stockholders Meeting (as defined in Section 2.23), (iii) such
consents, approvals, orders, authorizations, registrations, declarations and
filings as may be required under applicable state securities laws and the
securities laws of any foreign country; and (iv) such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not have a Material Adverse Effect on Medicus and would not prevent,
or materially alter or delay any of the transactions contemplated by this
Agreement.
 
     2.4  SEC Documents; Financial Statements. Medicus has furnished to
QuadraMed a true and complete copy of each statement, report, registration
statement (with the prospectus in the form filed pursuant to Rule 424(b) of the
Securities Act of 1933, as amended (the "Securities Act")), definitive proxy
statement and other filing filed with the SEC by Medicus since March 1, 1996,
and, prior to the Effective Time, Medicus will have furnished QuadraMed with
true and complete copies of any additional documents filed with the SEC
 
                                       A-7
<PAGE>   86
 
by Medicus prior to the Effective Time (collectively, the "Medicus SEC
Documents"). In addition, Medicus has made available to QuadraMed all exhibits
to the Medicus SEC Documents filed prior to the date hereof, and will promptly
make available to QuadraMed all exhibits to any additional Medicus SEC Documents
filed prior to the Effective Time. All documents required to be filed as
exhibits to the Medicus SEC Documents have been so filed, and all material
contracts so filed as exhibits are in full force and effect, except those which
have expired in accordance with their terms, and neither Medicus nor any of its
subsidiaries is in default thereunder. As of their respective filing dates, the
Medicus SEC Documents complied in all material respects with the requirements of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Securities Act, and none of the Medicus SEC Documents 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 made therein, in light of the
circumstances in which they were made, not misleading, except to the extent
corrected by a subsequently filed Medicus SEC Document. The financial statements
of Medicus, including the notes thereto, included in the Medicus SEC Documents
(the "Medicus Financial Statements") were complete and correct in all material
respects as of their respective dates, complied as to form in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto as of their respective dates,
and have been prepared in accordance with generally accepted accounting
principles applied on a basis consistent throughout the periods indicated and
consistent with each other (except as may be indicated in the notes thereto or,
in the case of unaudited statements included in Quarterly Reports on Form 10-Q,
as permitted by Form 10-Q of the SEC). The Medicus Financial Statements fairly
present the consolidated financial condition and operating results of Medicus
and its subsidiaries at the dates and during the periods indicated therein
(subject, in the case of unaudited statements, to normal, recurring year-end
adjustments). There has been no change in Medicus accounting policies except as
described in the notes to the Medicus Financial Statements.
 
     2.5  Absence of Certain Changes. Since August 31, 1997 (the "Medicus
Balance Sheet Date"), Medicus has conducted its business in the ordinary course
consistent with past practice and, except as disclosed in the Medicus SEC
Documents, there has not occurred: (i) any change, event or condition (whether
or not covered by insurance) that has resulted in, or might reasonably be
expected to result in, a Material Adverse Effect to Medicus; (ii) any
acquisition, sale or transfer of any material asset of Medicus or any of its
subsidiaries other than in the ordinary course of business and consistent with
past practice; (iii) any change in accounting methods or practices (including
any change in depreciation or amortization policies or rates) by Medicus or any
revaluation by Medicus of any of its or any of its subsidiaries' assets; (iv)
any declaration, setting aside, or payment of a dividend or other distribution
with respect to the shares of Medicus, or any direct or indirect redemption,
purchase or other acquisition by Medicus of any of its shares of capital stock;
(v) any material contract entered into by Medicus or any of its subsidiaries,
other than in the ordinary course of business and as provided to QuadraMed, or
any material amendment or termination of, or default under, any material
contract to which Medicus or any of its subsidiaries is a party or by which it
is bound; or (vi) any negotiation or agreement by Medicus or any of its
subsidiaries to do any of the things described in the preceding clauses (i)
through (v) (other than negotiations with QuadraMed and its representatives
regarding the transactions contemplated by this Agreement).
 
     2.6  Absence of Undisclosed Liabilities. Medicus has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet included in Medicus' Quarterly Report on Form 10-Q for the period
ended August 31, 1997 (the "Medicus Balance Sheet"), (ii) those incurred in the
ordinary course of business and not required to be set forth in the Medicus
Balance Sheet under generally accepted accounting principles, (iii) those
incurred in the ordinary course of business since the Medicus Balance Sheet Date
and consistent with past practice; and (iv) those incurred in connection with
the execution of this Agreement.
 
     2.7  Litigation. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Medicus or any of its
subsidiaries, threatened against Medicus or any of its subsidiaries or any of
their respective properties or any of their respective officers or directors (in
their capacities as such) that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on Medicus.
 
                                       A-8
<PAGE>   87
 
There is no judgment, decree or order against Medicus or any of its
subsidiaries, or, to the knowledge of Medicus and its subsidiaries, any of their
respective directors or officers (in their capacities as such), that could
prevent, enjoin, alter or materially delay any of the transactions contemplated
by this Agreement, or that could reasonably be expected to have a Material
Adverse Effect on Medicus.
 
     2.8  Restrictions on Business Activities. There is no material agreement,
judgment, injunction, order or decree binding upon Medicus or any of its
subsidiaries which has or reasonably could be expected to have the effect of
prohibiting or materially impairing any current or future business practice of
Medicus or any of its subsidiaries, any acquisition of property by Medicus or
any of its subsidiaries or the conduct of business by Medicus or any of its
subsidiaries as currently conducted or as proposed to be conducted by Medicus or
any of its subsidiaries.
 
     2.9  Governmental Authorization. Medicus and each of its subsidiaries have
obtained each federal, state, county, local or foreign governmental consent,
license, permit, grant, or other authorization of a Governmental Entity (i)
pursuant to which Medicus or any of its subsidiaries currently operates or holds
any interest in any of its properties or (ii) that is required for the operation
of Medicus' or any of its subsidiaries' business or the holding of any such
interest ((i) and (ii) herein collectively called "Medicus Authorizations"), and
all of such Medicus Authorizations are in full force and effect, except where
the failure to obtain or have any of such Medicus Authorizations could not
reasonably be expected to have a Material Adverse Effect on Medicus.
 
     2.10  Title to Property. Medicus and its subsidiaries have good and valid
title to all of their respective properties, interests in properties and assets,
real and personal, reflected in the Medicus Balance Sheet or acquired after the
Medicus Balance Sheet Date (except properties, interests in properties and
assets sold or otherwise disposed of since the Medicus Balance Sheet Date in the
ordinary course of business), or in the case of leased properties and assets,
valid leasehold interests therein, free and clear of all mortgages, liens,
pledges, charges or encumbrances of any kind or character, except (i) the lien
of current taxes not yet due and payable, (ii) such imperfections of title,
liens and easements as do not and will not materially detract from or interfere
with the use of the properties subject thereto or affected thereby, or otherwise
materially impair business operations involving such properties and (iii) liens
securing debt which is reflected on the Medicus Balance Sheet. The plants,
property and equipment of Medicus and its subsidiaries that are used in the
operations of their businesses are in good operating condition and repair. All
properties used in the operations of Medicus and its subsidiaries are reflected
in the Medicus Balance Sheet to the extent generally accepted accounting
principles require the same to be reflected. Schedule 2.10 identifies each
parcel of real property owned or leased by Medicus or any of its subsidiaries.
 
     2.11  Intellectual Property.
 
     (a) Medicus and its subsidiaries own, or are licensed or otherwise possess
legally enforceable rights to use all patents, trademarks, trade names, service
marks, copyrights, and any applications therefor, maskworks, net lists,
schematics, technology, know-how, trade secrets, inventory, ideas, algorithms,
processes, computer software programs or applications (in both source code and
object code form), and tangible or intangible proprietary information or
material ("Intellectual Property") that are used in the business of Medicus and
its subsidiaries as currently conducted or as proposed to be conducted by
Medicus and its subsidiaries, except to the extent that the failure to have such
rights have not had and would not reasonably be expected to have a Material
Adverse Effect on Medicus.
 
     (b) Medicus has provided to QuadraMed (i) all patents and patent
applications and all registered and unregistered trademarks, trade names and
service marks, registered and unregistered copyrights, and maskworks, which
Medicus considers to be material to its business and included in the
Intellectual Property, including the jurisdictions in which each such
Intellectual Property right has been issued or registered or in which any
application for such issuance and registration has been filed, (ii) all
licenses, sublicenses and other agreements as to which Medicus is a party and
pursuant to which any person is authorized to use any Intellectual Property, and
(iii) all licenses, sublicenses and other agreements as to which Medicus is a
party and pursuant to which Medicus is authorized to use any third party
patents, trademarks or copyrights,
 
                                       A-9
<PAGE>   88
 
including software ("Third Party Intellectual Property Rights") which are
incorporated in, are, or form a part of any Medicus product that is material to
its business.
 
     (c) To Medicus' knowledge, there is no unauthorized use, disclosure,
infringement or misappropriation of any Intellectual Property rights of Medicus
or any of its subsidiaries, any trade secret material to Medicus or any of its
subsidiaries, or any Intellectual Property right of any third party to the
extent licensed by or through Medicus or any of its subsidiaries, by any third

to indemnify any other person against any charge of infringement of any
Intellectual Property, other than indemnification provisions contained in
purchase orders arising in the ordinary course of business.
 
     (d) Medicus is not, nor will it be as a result of the execution and
delivery of this Agreement or the performance of its obligations under this
Agreement, in breach of any license, sublicense or other agreement relating to
the Intellectual Property or Third Party Intellectual Property Rights, the
breach of which would have a Material Adverse Effect on Medicus.
 
     (e) All patents, registered trademarks, service marks and copyrights held
by Medicus are valid and subsisting. Medicus (i) has not been sued in any suit,
action or proceeding which involves a claim of infringement of any patents,
trademarks, service marks, copyrights or violation of any trade secret or other
proprietary right of any third party and (ii) has not brought any action, suit
or proceeding for infringement of Intellectual Property or breach of any license
or agreement involving Intellectual Property against any third party. The
manufacture, marketing, licensing or sale of Medicus' products does not infringe
any patent, trademark, service mark, copyright, trade secret or other
proprietary right of any third party, except where such infringement would not
have a Material Adverse Effect on Medicus.
 
     (f) Medicus has secured valid written assignments from all consultants and
employees who contributed to the creation or development of Intellectual
Property of the rights to such contributions that Medicus does not already own
by operation of law.
 
     (g) Medicus has taken all reasonable and appropriate steps to protect and
preserve the confidentiality of all Intellectual Property not otherwise
protected by patents, or patent applications or copyright ("Confidential
Information"). All use, disclosure or appropriation of Confidential Information
owned by Medicus by or to a third party has been pursuant to the terms of a
written agreement between Medicus and such third party. All use, disclosure or
appropriation of Confidential Information not owned by Medicus has been pursuant
to the terms of a written agreement between Medicus and the owner of such
Confidential Information, or is otherwise lawful.

continued validity and effectiveness of any such Tax exemptions or other
Tax-sharing agreement or order.
 
     2.14  Employee Benefit Plans.
 
     (a) Schedule 2.14 lists, with respect to Medicus, any subsidiary of Medicus
and any trade or business (whether or not incorporated) which is treated as a
single employer with Medicus (an "ERISA Affiliate") within the meaning of
Section 414(b), (c), (m) or (o) of the Code, (i) all material employee benefit
plans (as defined in Section 3(3) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA")), (ii) each loan to a non-officer employee in
excess of $50,000, loans to officers and directors and any stock option, stock
purchase, phantom stock, stock appreciation right, supplemental retirement,
severance, sabbatical, medical, dental, vision care, disability, employee
relocation, cafeteria benefit (Code section 125) or dependent care (Code Section
129), life insurance or accident insurance plans, programs or arrangements,
(iii) all bonus, pension, profit sharing, savings, deferred compensation or
incentive plans, programs or arrangements, (iv) other fringe or employee benefit
plans, programs or arrangements that apply to senior management of Medicus and
that do not generally apply to all employees, and (v) any current or former
employment or executive compensation or severance agreements, written or
otherwise, as to which unsatisfied obligations of Medicus of greater than
$50,000 remain for the benefit of, or relating to, any present or former
employee, consultant or director of Medicus (together, the "Medicus Employee
Plans").
 
     (b) Medicus has furnished to QuadraMed a copy of each of the Medicus
Employee Plans and related plan documents (including trust documents, insurance
policies or contracts, employee booklets, summary plan descriptions and other
authorizing documents, and, to the extent still in its possession, any material
employee communications relating thereto) and has, with respect to each Medicus
Employee Plan which is subject to ERISA reporting requirements, provided copies
of the Form 5500 reports filed for the last three plan years. Any Medicus
Employee Plan intended to be qualified under Section 401(a) of the Code has
either obtained from the Internal Revenue Service a favorable determination
letter as to its qualified status under the Code, including all amendments to
the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or
has applied to the Internal Revenue Service for such a determination letter
prior to the expiration of the requisite period under applicable Treasury
Regulations or Internal Revenue Service pronouncements in which to apply for
such determination letter and to make any amendments necessary to obtain a
favorable determination. Medicus has also furnished QuadraMed with the most
recent Internal Revenue Service determination letter issued with respect to each
such Medicus Employee Plan, and nothing has occurred since the issuance of each
such letter which could reasonably be expected to cause the loss of the
tax-qualified status of any Medicus Employee Plan subject to Code Section
401(a).
 
     (c) (i) Except as disclosed on Schedule 2.14, none of the Medicus Employee
Plans promises or provides retiree medical or other retiree welfare benefits to
any person; (ii) there has been no "prohibited transaction," as such term is
defined in Section 406 of ERISA and Section 4975 of the Code, with respect to
any Medicus Employee Plan, which could reasonably be expected to have, in the
aggregate, a Material Adverse Effect; (iii) each Medicus Employee Plan has been
administered substantially in accordance with its terms and in compliance with
the requirements prescribed by any and all statutes, rules and regulations
(including ERISA and the Code), except as would not have, in the aggregate, a
Material Adverse Effect, and Medicus and each subsidiary or ERISA Affiliate have
performed all obligations required to be performed by them under, are not in any
respect in default under or violation of, and have no knowledge of any default
or violation by any other party to, any of the Medicus Employee Plans, which
default or violation could reasonably be expected to have a Material Adverse
Effect on Medicus; (iv) neither Medicus nor any subsidiary or ERISA Affiliate is
subject to any liability or penalty under Sections 4976 through 4980 of the Code
or Title I of ERISA with respect to any of the Medicus Employee Plans, other
than obligations for the payment of benefits in the normal operation of the
Plan, and obligations which would not in the aggregate have a Material Adverse
Effect on Medicus; (v) all material contributions required to be made by Medicus
or any subsidiary or ERISA Affiliate to any Medicus Employee Plan have been made
on or before their due dates and any accruals required by general accepted
accounting principles ("GAAP") for contributions to each Medicus Employee Plan
for the current plan years are reflected on the financial statements of Medicus;
(vi) with respect to each Medicus Employee Plan, no "reportable event" within
the meaning of Section 4043 of ERISA (excluding any such event for
 
                                      A-12
<PAGE>   91
 
which the thirty (30) day notice requirement has been waived under the
regulations to Section 4043 of ERISA) nor any event described in Section 4062,
4063 or 4041 or ERISA has occurred; and (vii) neither Medicus nor any subsidiary
or ERISA Affiliate has incurred or expects to incur any liability under Title IV
of ERISA or Section 412 of the Code. With respect to each Medicus Employee Plan
subject to ERISA as either an employee pension plan within the meaning of
Section 3(2) of ERISA or an employee welfare benefit plan within the meaning of
Section 3(1) of ERISA, Medicus has prepared in good faith and timely filed all
requisite governmental reports (which were true and correct as of the date
filed) and has properly and timely filed and distributed or posted all notices
and reports to employees required to be filed, distributed or posted with
respect to each such Medicus Employee Plan, except for failures which would not
have a Material Adverse Effect on Medicus. No suit, administrative proceeding,
action or other litigation has been brought, or to the best knowledge of Medicus
is threatened, against or with respect to any such Medicus Employee Plan,
including any audit or inquiry by the IRS or United States Department of Labor.
Neither Medicus nor any Medicus subsidiary or other ERISA Affiliate is a party
to, or has made any contribution to or otherwise incurred any obligation under,
any "multiemployer plan" as defined in Section 3(37) of ERISA.
 
     (d) With respect to each Medicus Employee Plan, Medicus and each of its
United States subsidiaries have complied with (i) the applicable health care
continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the proposed regulations thereunder and
(ii) the applicable requirements of the Family Leave Act of 1993 and the
regulations thereunder, except to the extent that such failure to comply would
not, in the aggregate, have a Material Adverse Effect.
 
     (e) The consummation of the transactions contemplated by this Agreement
will not entitle any current or former employee or other service provider of
Medicus, any Medicus subsidiary or any other ERISA Affiliate to severance
benefits or any other payment, except as vesting, or increase the amount of
compensation due any such employee or service provider.
 
     (f) Except as disclosed on Schedule 2.14, there has been no amendment to,
written interpretation or announcement (whether or not written) by Medicus, any
Medicus subsidiary or other ERISA Affiliate relating to, or change in
participation or coverage under, any Medicus Employee Plan which would
materially increase the expense of maintaining such Plan above the level of
expense incurred with respect to that Plan for the most recent fiscal year
included in Medicus' financial statements.
 
     2.15  Certain Agreements Affected by the Merger. Neither the execution and
delivery of this Agreement nor the consummation of the transaction contemplated
hereby will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute, bonus or otherwise) becoming due to
any director or employee of Medicus or any of its subsidiaries, (ii) materially

validly issued, fully paid and nonassessable. All of the outstanding shares of
capital stock of each such subsidiary are owned by QuadraMed free and clear of
all liens, charges, claims or encumbrances or rights of others. There are no

Except as disclosed in the QuadraMed SEC Documents (as defined in Section 3.4),
QuadraMed does not directly or indirectly own any equity or similar interest in,

previously delivered to Medicus. There are no other outstanding shares of
capital stock or voting securities of QuadraMed other than shares of QuadraMed
Common Stock issued after October 21, 1997 upon the exercise of options or
warrants. The authorized capital stock of Merger Sub consists of 1,000 shares of
Common Stock, $.01 par value, all of which are issued and outstanding and are

any liens or encumbrances other than any liens or encumbrances created by or
imposed upon the holders thereof. Other than pursuant to this Agreement, and
options or warrants that were outstanding as of October 21, 1997, there are no
other options, warrants, calls, rights, commitments or agreements of any
character to which QuadraMed or Merger Sub is a party or by which either of them
is bound obligating QuadraMed or Merger Sub to issue, deliver, sell, repurchase
or redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
shares of the capital stock of QuadraMed or Merger Sub or obligating QuadraMed
or Merger Sub to grant, extend or enter into any such option, warrant, call,

consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of QuadraMed and Merger Sub. This
Agreement has been duly executed and delivered by QuadraMed and Merger Sub and
constitutes the valid and binding obligations of QuadraMed and Merger Sub. The
execution and delivery of this Agreement do not, and the consummation of the
transactions contemplated hereby will not, conflict with, or result in any

of Incorporation or Bylaws of QuadraMed or any of its subsidiaries, as amended,
or (ii) any material mortgage, indenture, lease, contract or other agreement or

statute, law, ordinance, rule or regulation applicable to QuadraMed or any of
its subsidiaries or their properties or assets, except where such conflict,
violation, default, termination, cancellation or acceleration with respect to
the foregoing provisions of (ii) would not have had and would not reasonably be
expected to have a Material Adverse Effect on QuadraMed. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
Governmental Entity, is required by or with respect to QuadraMed or any of its
subsidiaries in connection with the execution and delivery of this Agreement by

registrations which, if not obtained or made,
 
                                      A-16

Securities Act), definitive proxy statement, and other filing filed with the SEC
by QuadraMed since March 31, 1997, and, prior to the Effective Time, QuadraMed
will have furnished Medicus with true and complete copies of any additional
documents filed with the SEC by QuadraMed prior to the Effective Time

nor any of its subsidiaries is in default thereunder. As of their respective
filing dates, the QuadraMed SEC Documents complied in all material respects with
the requirements of the Exchange Act and the Securities Act, and none of the
QuadraMed SEC Documents 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 made therein, in light of the circumstances in which they
were made, not misleading, except to the extent corrected by a subsequently
filed QuadraMed SEC Document. The financial statements of QuadraMed, including
the notes thereto, included in the QuadraMed SEC Documents (the "QuadraMed
Financial Statements") were complete and correct in all material respects as of
their respective dates, complied as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto as of their respective dates, and have been
prepared in accordance with generally accepted accounting principles applied on
a basis consistent throughout the periods indicated and consistent with each
other (except as may be indicated in the notes thereto or, in the case of
unaudited statements included in Quarterly Reports on Form 10-Q, as permitted by
Form 10-Q of the SEC). The QuadraMed Financial Statements fairly present the
consolidated financial condition and operating results of QuadraMed and its
subsidiaries at the dates and during the periods indicated therein (subject, in

Balance Sheet Date"), QuadraMed has conducted its business in the ordinary
course consistent with past practice and there has not occurred: (i) any change,
event or condition (whether or not covered by insurance) that has resulted in,
or might reasonably be expected to result in, a Material Adverse Effect to
QuadraMed; (ii) any acquisition, sale or transfer of any material asset of
QuadraMed or any of its subsidiaries other than in the ordinary course of
business and consistent with past practice; (iii) any material change in
accounting methods or practices (including any change in depreciation or
amortization policies or rates) by QuadraMed or any revaluation by QuadraMed of
any of its assets; (iv) any declaration, setting aside, or payment of a dividend
or other distribution with respect to the shares of QuadraMed, or any direct or
indirect redemption, purchase or other acquisition by QuadraMed of any of its
shares of capital stock; or (v) any negotiation or agreement by QuadraMed or any
of its subsidiaries to do any of the things described in the preceding clauses
(i) through (iv) (other than negotiations with Medicus and its representatives
regarding the transactions contemplated by this Agreement).
 
     3.6  Absence of Undisclosed Liabilities. QuadraMed has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet included in QuadraMed's Quarterly Report on Form 10-Q for the
period ended June 30, 1997 (the "QuadraMed Balance Sheet"), (ii) those incurred
in the ordinary course of business and not required to be set forth in the
QuadraMed Balance Sheet under generally accepted accounting principles, and
(iii) those incurred in the ordinary course of business since the QuadraMed
Balance Sheet Date and consistent with past practice.
 
     3.7  Litigation. There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of QuadraMed or any of
its subsidiaries, threatened against QuadraMed or any of its subsidiaries or any
of their respective properties or any of their respective officers or directors
(in their capacities as such) that,
 
                                      A-17
<PAGE>   96
 
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect on QuadraMed. There is no judgment, decree or order
against QuadraMed or any of its subsidiaries or, to the knowledge of QuadraMed
or any of its subsidiaries, any of their respective directors or officers (in
their capacities as such) that could prevent, enjoin, alter or materially delay
any of the transactions contemplated by this Agreement, or that could reasonably
be expected to have a Material Adverse Effect on QuadraMed.
 
     3.8  Restrictions on Business Activities. There is no material agreement,
judgment, injunction, order or decree binding upon QuadraMed or any of its
subsidiaries which has or reasonably could be expected to have the effect of
prohibiting or materially impairing any current or future business practice of
QuadraMed or any of its subsidiaries, any acquisition of property by QuadraMed
or any of its subsidiaries or the conduct of business by QuadraMed or any of its
subsidiaries as currently conducted or as proposed to be conducted by QuadraMed
or any of its subsidiaries.
 
     3.9  Governmental Authorization. QuadraMed and each of its subsidiaries
have obtained each federal, state, county, local or foreign governmental
consent, license, permit, grant, or other authorization of a Governmental Entity

holds any interest in any of its properties or (ii) that is required for the
operation of QuadraMed's or any of its subsidiaries' business or the holding of
any such interest ((i) and (ii) herein collectively called "QuadraMed
Authorizations"), and all of such QuadraMed Authorizations are in full force and
effect, except where the failure to obtain or have any of such QuadraMed
Authorizations could not reasonably be expected to have a Material Adverse
Effect on QuadraMed.
 
     3.10  Compliance With Laws. Each of QuadraMed and its subsidiaries has
complied with, are not in violation of, and have not received any notices of
violation with respect to, any federal, state, local or foreign statute, law or
regulation with respect to the conduct of its business, or the ownership or
operation of its business, except for such violations or failures to comply as
could not be reasonably expected to have a Material Adverse Effect on QuadraMed.
 
     3.11  [Intentionally Omitted].
 
     3.12  Broker's and Finders' Fees. QuadraMed has not incurred, nor will it
incur, directly or indirectly, any liability for brokerage or finders' fees or

promptly inform Medicus. Notwithstanding the foregoing, QuadraMed and Merger Sub

such determination by the Medicus Board of Directors and provides QuadraMed with
a true and complete copy of the Superior Proposal received from such third
party, if the Superior Proposal is in writing, or a complete written summary
thereof, if it is not in writing, and provides QuadraMed with all documents
containing or referring to non-public information of Medicus that are supplied
to such third party; provided further, that (A) the Board of Directors of
Medicus has determined, with the advice of Medicus' investment bankers, that
such third party is capable of making a Superior Proposal upon satisfactory
completion of such third party's review of the information supplied by Medicus,
(B) the third party has stated that it intends to make a Superior Proposal, (C)
Medicus may not provide any non-public

<PAGE>   100
 
information to any such third party if it has not prior to the date thereof
provided such information to QuadraMed or QuadraMed's representatives, (D)
Medicus notifies QuadraMed in advance of any disclosure of non-public
information to any such third party, with a description of the information
proposed to be disclosed, and (E) Medicus provides such non-public information
pursuant to a non-disclosure agreement at least as restrictive as the
Confidentiality Agreement (as defined in Section 5.4). Medicus will promptly
notify QuadraMed after receipt of any Takeover Proposal or any notice that any
person is considering making a Takeover Proposal or any request for non-public
information relating to Medicus or any of its subsidiaries or for access to the
properties, books or records of Medicus or any of its subsidiaries by any person
that has advised Medicus that it may be considering making, or that has made, a
Takeover Proposal and will keep QuadraMed fully informed of the status and
details of any such Takeover Proposal notice, request or any correspondence or
communications related thereto and shall provide QuadraMed with a true and
complete copy of such Takeover Proposal notice or request or correspondence or
communications related thereto, if it is in writing, or a complete written
summary thereof, if it is not in writing. For purposes of this Agreement,
"Takeover Proposal" means any offer or proposal for, or any indication of
interest in, a merger or other business combination involving Medicus or any of
its subsidiaries or the acquisition of any significant equity interest in, or a
significant portion of the assets of, Medicus or any of its subsidiaries, other

Incorporation and Bylaws or any indemnification agreement with Medicus' officers
and directors to which Medicus is a party, in each case in effect on the date
hereof; provided, however, that such indemnification shall be subject to any
limitation imposed from time to time under applicable law. Without limitation of
the foregoing, in the event any such Indemnified Party is or becomes involved in
any capacity in any action, proceeding or investigation in connection with any
matter relating to this Agreement or the transactions contemplated hereby
occurring on or prior to the Effective Time, QuadraMed shall, or shall cause the
Surviving Corporation to, pay as incurred such Indemnified Party's reasonable
legal and other expenses (including the cost of any investigation and

to the extent provided under Medicus' Certificate of Incorporation and Bylaws or
the indemnification agreement with such Indemnified Party.
 
     (b) For two years after the Effective Time, QuadraMed will, or will cause
the Surviving Corporation to, use its best efforts to provide officers' and
directors' liability insurance in respect of acts or omissions occurring on or

5.16, it shall obtain as much comparable insurance as possible for an annual
premium equal to such maximum amount.
 
     (c) To the extent there is any claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time) against an
Indemnified Party that arises out of or pertains to any action or omission in
his or her capacity as a director, officer, employee, fiduciary or agent of
Medicus occurring prior to the Effective Time, or arises out of or pertains to
the transactions contemplated by this Agreement for a period of two years after

reasonably satisfactory to the Surviving Corporation and QuadraMed, (ii) the
Surviving Corporation and QuadraMed shall pay the reasonable fees and expenses
of such counsel, promptly after statements therefor are received and (iii) the

matter; provided, however, that neither the Surviving Corporation nor QuadraMed
shall be liable for any settlement effected without its written consent (which
consent shall not be unreasonably withheld); and provided, further, however,
that in the event that any claim or claim for indemnification are asserted or
made within such two-year period, all rights to indemnification in respect of
any such claim or claims shall continue until the disposition of any and all
such claims. The Indemnified Parties as a group may retain only one law firm (in
addition to local counsel) to represent them with respect to any single action
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any tow or more Indemnified
Parties.

The Board of Directors
Medicus Systems Corporation
One Rotary Center
Suite 1111
Evanston, IL 60201
 
Members of the Board:
 
     You have requested our opinion (the "Opinion") as to the fairness, from a
financial point of view, to the stockholders of Medicus Systems Corporation
("Medicus" or the "Company"), other than QuadraMed Corporation ("QuadraMed"), of
the consideration to be received by such holders pursuant to the Agreement and
Plan of Reorganization dated as of November 9, 1997 (the "Agreement") by and
among Medicus, QuadraMed and Medicus Acquisition Co., a wholly owned subsidiary
of QuadraMed ("Merger Sub").
 
     The Agreement provides that (i) Merger Sub will be merged with and into
Medicus (the "Merger") and (ii) each outstanding share of common stock of
Medicus (the "Medicus Common Stock") will be converted into the right to
receive, at the option of each shareholder, either (x) $7.50 in cash, (y) 0.3125
shares, subject to adjustment as described in the Agreement, (the "Exchange
Ratio") of QuadraMed common stock ("QuadraMed Common Stock") or (z) any
combination of QuadraMed Common Stock and cash, subject to certain adjustments
and restrictions (the "Consideration"). It is our understanding that the
transaction will be accounted for as a purchase for financial reporting purposes
and the Consideration will be taxable to Medicus shareholders when received.
 
     We understand that shortly after the execution of the Agreement, QuadraMed
acquired 56.7%, or 3,111,105 shares, of the outstanding capital stock of Medicus
through transactions with certain shareholders (the "Selling Shareholders"). We
further understand that QuadraMed paid for such shares $7.50 per share in cash
together with warrants entitling the Selling Shareholders to acquire 0.3125
shares of QuadraMed Common Stock for each share of Medicus Common Stock sold at
a price of $24.00 per share, subject to certain adjustments and restrictions.
 
     For the purposes of formulating the Opinion, we have, among other things:
 
          (i) Reviewed the Agreement and Plan of Reorganization dated as of
     November 9, 1997 by and among QuadraMed and Medicus;
 
          (ii) Discussed the terms of QuadraMed's acquisition of Resource Health
     Partners, L.P. ("RHP") with QuadraMed management;
 
          (iii) Interviewed management of Medicus and QuadraMed concerning the
     business prospects, financial outlook and operating plans of each company
     individually and combined;
 
          (iv) Reviewed certain historical Medicus and QuadraMed, and certain
     projected Medicus and QuadraMed (including RHP) financial statements and
     other relevant financial and operating data of Medicus and QuadraMed
     prepared by the respective company management teams;
 
          (v) Reviewed the historical stock trading patterns of both QuadraMed
     and Medicus and analyzed implied historical exchange ratios as well as the
     premium of the Consideration in relation to historical Medicus stock
     trading ranges;
 
                                       B-1
<PAGE>   111
 
          (vi) Reviewed the valuation of selected publicly-traded companies we
     deemed comparable and relevant to the Merger;
 
          (vii) Reviewed, to the extent publicly available, the financial terms
     of selected merger and acquisition transactions that we deemed comparable
     and relevant to the Merger;
 
          (viii) Reviewed the relevant contribution each of Medicus and
     QuadraMed is making to the combined company in terms of financial results
     and compared the implied values resulting from this analysis with the
     Consideration;
 
          (ix) Performed a discounted cash flow analysis of Medicus as a
     stand-alone entity based upon financial projections of Medicus management;
 
          (x) Performed a pro forma financial impact analysis of the combined
     entity, based upon financial projections provided by Medicus and QuadraMed;
     and
 
          (xi) Performed other such studies, analyses and inquiries and
     considered other such information as we deemed relevant.
 
     Volpe Brown Whelan & Company, LLC ("VBW&Co.") relied without independent
verification upon the accuracy and completeness of all of the financial,
accounting, legal, tax, operating and other information provided to VBW&Co. by
Medicus and QuadraMed and has relied upon the assurances of Medicus and
QuadraMed that all such information provided by them, respectively, is complete
and accurate in all material respects and that there is no additional material
information known to either of them that would make any of the information made
available to VBW&Co. either incomplete or misleading. Medicus has also retained
outside legal, accounting and tax advisors to advise on matters relating to the
Merger. Accordingly, VBW&Co. has relied on their advice and expresses no opinion
on such matters.
 
     Although we were informed by Medicus of certain discussions by the
management of Medicus with third parties concerning possible business
combinations, we were not requested to consider, and we are expressing no
opinion as to, the relative merits of the Merger as compared to any alternative
business strategies that might exist for Medicus or the effect of any other
transaction in which Medicus might engage.
 
     With respect to the projected financial data of Medicus and QuadraMed
(including RHP), all of which has been provided by the management of Medicus or
QuadraMed, as well as the combined business plan, VBW&Co. has relied upon
assurances of each company that such data has been prepared in good faith on a
reasonable basis reflecting the best currently available estimates and judgments
of Medicus and QuadraMed managements as to the future financial performance of
each company separately and as a combined company. Our Opinion is based, in
large part, on these projected financial data and estimates.
 
     VBW&Co. is relying upon the information provided to it by Medicus and
QuadraMed for the purposes of rendering the Opinion. VBW&Co. expresses no
opinion and has made no investigation with respect to the validity, accuracy or
completeness of the information provided to it and does not warrant any
projections included in such information. Actual results that Medicus or
QuadraMed might achieve in the future as stand-alone entities or as a combined
company may vary materially from those used in VBW&Co.'s analysis.
 
     VBW&Co. has assumed that the Merger will be consummated in accordance with
the terms of the Agreement and that no subsequent changes or amendments will be
made prior to closing. VBW&Co. has, furthermore, not made any independent
appraisals or valuations of any assets of Medicus or QuadraMed, nor has VBW&Co.
been furnished with any such appraisals or valuations. VBW&Co. has performed no
investigations relating to the representations and warranties made by Medicus or
QuadraMed, including representations with respect to intellectual property
rights and status of any litigation pending or threatened against either
company. While VBW&Co. believes that its review, as described herein, is an
adequate basis for the Opinion it has expressed, the Opinion is necessarily
based upon market, economic and other conditions that exist and can be evaluated
as of the date of the Opinion, and any change in such conditions would require a
re-evaluation of the Opinion.

     The Opinion addresses only the financial fairness of the Consideration to
the shareholders other than QuadraMed and does not address the relative merits
of the Merger and any alternatives to the Merger, the relative fairness of the
Consideration in comparison with the purchase price paid to the Selling
Shareholders, Medicus' decision to proceed with or the effect of the Merger, or
any other aspect of the Merger.
 
     The preparation of a fairness opinion involves various judgments as to
appropriate and relevant quantitative and qualitative methods of financial
analyses and the application of those methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to summary
description. Accordingly, we believe our analyses and the factors utilized in
such analysis must be considered as a whole and that considering any portion of
such analyses or factors, without considering all analyses and factors could
create a misleading or incomplete view of the process underlying the Opinion. In
our analyses, we made numerous assumptions with respect to industry performance,
general business and other conditions and matters, many of which are beyond
Medicus' or QuadraMed's control and are not susceptible to accurate prediction.
No opinion is expressed herein as to the future trading price or range of prices
of any securities of QuadraMed issued prior to or in conjunction with the
Merger. Furthermore, the Opinion does not constitute a recommendation as to the
Board of Directors' decision on whether to support the Merger and recommend it
to Medicus' stockholders and does not constitute a recommendation to
shareholders as to whether to vote in favor of the Merger. The Opinion and
related materials have been prepared for the use and benefit of the Board of
Directors of Medicus and may not be used for any other purpose, except that this
opinion may be included in any filing which Medicus makes with the Securities
and Exchange Commission with respect to the Merger (and included in a proxy
statement related to the Merger).
 
     As a customary part of its investment banking business, VBW&Co. engages in
the valuation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, secondary distributions of securities,
private placements and valuations for corporate and other purposes. In the
ordinary course of its business, VBW&Co. and its affiliates may actively trade
the equity securities of Medicus or QuadraMed for their own account and for the
accounts of customers and, accordingly, may at any time hold a long or short
position in such securities.
 
     As you are aware, VBW&Co. has been engaged by QuadraMed to provide
investment banking and financial advisory services to QuadraMed unrelated to the
Medicus transaction. To date no fees have been paid to VBW&Co. by QuadraMed. As
you are also aware, VBW&Co. has also been retained by RHP to provide financial
advice and a fairness opinion to RHP with respect to the acquisition of RHP by
QuadraMed. VBW&Co. will receive a fee for rendering its Opinion, no portion of
which is conditioned upon the Opinion being favorable.
 
     Based upon and subject to the foregoing limitations and restrictions and
after considering such other matters as we deem relevant, it is our opinion
that, as of the date hereof, the Consideration in the Merger is fair, from a
financial point of view, to the stockholders of Medicus, other than QuadraMed.
 
Very truly yours,

                SECTION 262 OF DELAWARE GENERAL CORPORATION LAW
 
     Appraisal Rights -- (a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec.228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of the stockholder's shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251 (other than a merger effected pursuant to
sec.251(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or
sec.264 of this title.
 
     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) 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 (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of sec.251 of this title.
 
     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to sec.251, 252, 254,
257, 258, 263 and 264 of this title to accept for such stock anything except:
 
          a. Shares of stock of the corporation surviving or resulting from such
     merger or consolidation, or depository receipts in respect thereof;
 
          b. Shares of stock of any other corporation, or depository receipts in
     respect thereof, which shares of stock (or depository receipts in respect
     thereof) or depository receipts at the effective date of the merger or
     consolidation will be either 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 holders;
 
          c. Cash in lieu of fractional shares or fractional depository receipts
     described in the foregoing subparagraphs a. and b. of this paragraph; or
 
          d. Any combination of the shares of stock, depository receipt and cash
     in lieu of fractional shares or fractional depository receipts described in
     the foregoing subparagraphs a., b. and c of this paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale
 
                                       C-1
<PAGE>   114
 
of all or substantially all of the assets of the corporation. If the certificate
of incorporation contains such a provision, the procedures of this section,
including those set forth in subsections (d) and (e) of this section, shall
apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares of which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consent to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec.228 or
     sec.253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice shall be given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within twenty days after the date of
     mailing of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given; provided that,
     if the notice is given on or after the effective date of the merger or
     consolidation, the record date shall be such effective date. If no record
     date is fixed and the notice is given prior to the effective date, the
     record date shall be the close of business on the day next preceding the
     day on which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise
 
                                       C-2
<PAGE>   115
 
entitled to appraisal rights, may file a petition in the Court of Chancery
demanding a determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
                                       C-3
<PAGE>   116
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholder of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (1) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145(a) of the Delaware General Corporation Law (the "DGCL")
provides in relevant part that "[a] corporation may indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or Agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or Agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful." With
respect to derivative actions, Section 145(b) of the DGCL provides in relevant
part that "[a] corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor
[by reason of his service in one of the capacities specified in the preceding
sentence] against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper."
 
     Article 5 of Medicus' Amended and Restated Bylaws provides that Medicus
shall indemnify each person who is or was a director or executive officer of
Medicus to the full extent permitted by the DGCL. Such Article also provides
that Medicus may, but is not required to, indemnify its employees and agents
(other than directors and officers) to the extent and in the manner permitted by
the DGCL.
 
     QuadraMed has entered into an indemnification agreement with each of its
directors and officers and intends to maintain insurance for the benefit of its
directors and officers insuring such persons against certain liabilities,
including liabilities under the securities laws.
 
     See Item 22 of this Registration Statement regarding the position of the
Securities and Exchange Commission on indemnification for liabilities arising

ITEM 22. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
QuadraMed pursuant to the foregoing provisions, or otherwise, QuadraMed has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by QuadraMed of expenses incurred or
paid by a director, officer or controlling person of QuadraMed 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,
QuadraMed 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.
 
     QuadraMed hereby undertakes:
 
          (1) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 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 the Registration Statement through the date of responding
     to the request;
 
          (2) 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 the registration statement when
     it became effective;
 
          (3) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of its annual report pursuant to
     section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
 
                                      II-2
<PAGE>   119
 
     where applicable, each filing of an employee benefit plan's annual report
     pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
     incorporated by reference in the registration statement shall be deemed to
     be a new registration statement relating to the securities offered therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof;
 
          (4) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which 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; and
 
          (5) That every prospectus (i) that is filed pursuant to paragraph (4)
     immediately preceding, or (ii) that purports to meet the requirements of
     section 10(a)(3) of the 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
     the registration statement and will not be used until such amendment is
     effective, and that, for purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

ITEM 1. BUSINESS
 
GENERAL
 
     Medicus Systems Corporation ("Medicus" or the "Company") develops, markets,
and supports a family of specialized integrated software products utilized by
healthcare financial administrators, physicians and nursing executives, health
information and other administrative departments to capture, structure and
analyze clinical, operational and financial information. Medicus' specialized
software applications and services allow these professionals to measure, monitor
and manage organizational performance and optimize outcomes. Many of these
products incorporate features that enable them to facilitate the exchange of
data with information systems used by other Medicus clients. Medicus also
provides product-related maintenance and support services. During the year, the
Company discontinued the line of business which managed the information systems
of healthcare delivery organizations.
 
     Medicus' products are currently used by more than 1,200 clients. Clients
include hospitals, academic medical centers, managed care organizations,
community care networks, integrated health systems, primary care and
multi-specialty physician groups, government agencies, and other organizations.
 
  Basis of Presentation
 
     Prior to March 1, 1996, the Company's predecessor (the "Predecessor
Corporation") operated a software and related services business and a small
managed care business. In February 1995, the Predecessor Corporation adopted a
formal plan to discontinue its managed care business, transfer the assets and
liabilities of this business to a newly-formed subsidiary, and distribute the
shares of this newly-formed subsidiary to its stockholders. In November 1995,
following meetings with the Internal Revenue Service and in order to insure
qualification of the transaction as a tax-free spin-off, the form of the
transaction was changed. Instead of transferring the assets and liabilities of
its managed care business to a newly-formed subsidiary, the Predecessor
Corporation formed a new Delaware subsidiary, Medicus Systems Software, Inc., to
which it transferred all of its assets and liabilities excluding only the
defined assets and liabilities of its managed care business. In turn, the stock
of this newly-formed subsidiary was distributed on a share-for-share basis to
the stockholders of the Predecessor Corporation (the "Distribution"), the name
of the subsidiary was changed to Medicus Systems Corporation, and the name of
the Predecessor Corporation was changed to Managed Care Solutions, Inc. ("MCS").
Simultaneously, the outstanding stock of the Predecessor Corporation was split
in reverse one-for-three so that following the Distribution, the Predecessor
Corporation's stockholders owned one share of the Company (the successor, in
substance, to the Predecessor Corporation which owned all of the assets and was
liable for all obligations of the Predecessor Corporation except those
specifically related to the Predecessor Corporation's managed care business) and
one-third of a share of MCS for every share of the Predecessor Corporation
previously owned.
 
     Although the Company is, in substance, the Predecessor Corporation's
successor, the financial statements of the Company have been prepared as if the
Company had operated as a free-standing entity for all the periods presented
(excluding certain incremental corporate expenses that would have been incurred
had it operated on a stand-alone basis). Accordingly, the financial statements
include those assets, liabilities, revenues and expenses directly attributable
to the Company's operations and exclude those specifically related to the
managed care business. The Company has adopted this presentation because the
Company believes that this presentation most fairly represents its financial
condition, results of operations and changes in stockholders' equity and cash
flows. The financial statements included herein for periods prior to the
Distribution do not necessarily reflect what the financial position and results
of operation of the Company would have been had it operated as a stand-alone
entity during the periods covered, and may not be indicative of future
operations or financial position.

  Software Products and Services
 
     Provider organizations are continuously challenged by purchasers to
demonstrate improvement toward optimal financial and clinical outcomes as they
compete for managed care contracts. Medicus' specialized products are designed
to capture, structure and analyze data in such a way as to assist providers in
optimizing the outcomes that are most important to buyers. Medicus focuses on
providing products in specialized market niches that are critical to the
information and decision support needs of healthcare providers. The Company
employs standard interface systems to accomplish the necessary integration with
existing transaction processing systems.
 
  Clinical Data Systems (CDS)
 
     CDS is an integrated encoding system and data repository that enables the
healthcare provider to classify, capture, validate, and analyze clinical data.
The system is a tool that implements a uniform clinical database to measure and
monitor patient, clinical and financial outcomes. This expert encoding system
aids in optimizing prospective payment reimbursement for both inpatient and
ambulatory care services. It captures and validates clinical indicators,
severity and risk factors as well as patient demographics data, diagnoses and
procedures. Clinical data forms the basis upon which (i) the healthcare provider
identifies cases for clinical appropriateness studies, (ii) the Joint Commission
on Accreditation of Healthcare Organizations (JCAHO), The National Committee on
Quality Assurance utilizing its Health Plan and Employer Data and Information
Set (HEDIS), and state agencies measure performance, and (iii) the health care
provider estimates service volumes and costs in competing for managed care
contracts. By validating data at the point of capture and linking it to a
Diagnosis Related Group (DRG), the clinical data system creates an accurate and
complete data repository that provides the information required to manage costs
and improve clinical effectiveness and service efficiency.
 
     As of May 31, 1997, the Company had licensed CDS software for use by 600
hospitals and other users. These other users include the Health Care Financing
Administration (HCFA), several professional peer review organizations, the
American Hospital Association (AHA), and numerous consulting and auditing firms.
The CDS product line currently includes two integrated modules:
 
     The WinCoder+ module is a Windows-based encoding tool released in 1995. The
WinCoder+ module supports integrated data encoding, editing and
diagnosis-related grouping for all patient types, including inpatient
admissions, emergency room admissions, referrals, and ambulatory admissions and
procedures. Utilizing "expert-system" logic, WinCoder+ delivers advice and
classification guidance to identify errors of omission in clinical documentation
in an effort to optimize Medicare and capitated reimbursement. The system also
captures reliable and consistent clinical data for both the financial and
clinical users. The WinCoder+ product includes a Clinical and Financial
Optimizer which uses "expert-system" logic to assist the user in identifying
errors of omission in clinical documentation, and proposes related codes or
other alternatives which may be applicable and result in more appropriate
reimbursement.
 
     The WinCOLLECT module organizes and structures a uniform clinical data set
to describe a patient population, including its clinical and financial
characteristics, and to evaluate the quality and appropriateness of care.
WinCOLLECT is a data capture system that validates entries for internal
consistency at the point of collection. Because each organization has unique
requirements and is responding to volatile external forces, this module supports
user customization with user-defined tables and calculated fields. WinCOLLECT is
a core technology for the healthcare organization to support medical records,
quality assurance, physician credentialing, utilization review, discharge
planning, infection control and risk management functions. This module captures
the clinical data necessary to meet the external reporting requirements of
JCAHO, HCFA, professional review organizations, state data agencies and other
organizations.
 
     The CDS products are licensed under non-exclusive perpetual licenses.
Leasing options are also offered. Total client fees for CDS products range from
$15,000 to $250,000 and are comprised of license fees charged per module and per
user, implementation, hardware and technical fees. At the time a license is
granted, Medicus generally enters into a one-year maintenance and support
agreement for an annual fee that is based
 
                                        3
<PAGE>   124
 
on a percentage of the then current license fee and which is renewable at then
current rates for successive one-year terms.
 
  Decision Support Systems (DSS)
 
     This division offers two lines of products, Enterprise Analyst and Resource
Case Management. As of May 31, 1997, Medicus had licensed its DSS software for
use by 150 hospital customers.
 
     The Company recently introduced to the market the Enterprise Analyst -- the
next generation of Decision Support Systems to assist integrated healthcare
delivery systems in responding to the rapidly changing healthcare environment
via a powerful client/server architecture and one of the most comprehensive
functionalities available today.
 
     The Enterprise Analyst is a fully integrated, enterprise wide decision
support system application designed to allow our customers to maximize all
components of value -- quality, outcomes and cost containment. With the
Enterprise Analyst, healthcare organizations capture, manage, and analyze
clinical and operational costs, case mix data, payer contracts, physician
profiles, resource utilization, and patient care outcomes data. The Enterprise
Analyst is comprised of three integrated modules:
 
     Enterprise Costing allows a healthcare enterprise to measure, monitor and
compare costs across the continuum of care for all care settings. This product
allows healthcare managers to easily obtain the information needed to make
optimal decisions regarding resource allocation and cost containment. The system
supports flexible cost determination based on a range of methodologies including
micro-costing, engineered standards, relative value units, activity based
costing, and ratio of cost to charges.
 
     Enterprise Case Mix and Contract Management (CM2) is a powerful, new
combination case mix and contract management system. CM2 features a fully
integrated clinical and financial database. The system is designed to analyze
clinical outcomes against key variables such as revenues, costs, severity,
physician to discover the techniques that result in desirable outcomes and lower
costs. CM2 is designed to calculate reimbursement based on payer contract terms,
track contractual allowances accurately to provide precise profitability
measures and variance analyses of payer contracts, generate payer and patient
letters, and provide a contract modeling capability that can handle any
reimbursement model for more accurate negotiations.
 
     Enterprise Performance Measurement and Modeling (PMM) effectively
integrates strategic planning with the operational planning process across the
enterprise. PMM works in a distributed environment and provides a dynamic
statistics file for comprehensive flexible budgeting and financial modeling. The
system supports enterprise wide detailed wage and salary planning, financial
forecasting, cost allocation, contractual allowance determination, and
procedural rate setting.
 
     Resource Case Management, a line of DSS products, provides case managers
and other personnel the ability to evaluate and manage patient care resources on
a daily basis. The Resource Case Management system is comprised of three
integrated modules each of which addresses a distinct and logical part of the
case management and analysis process:
 
     The Pathway Generator module analyzes historical case data and generates
resource pathways.
 
     The Pathway Monitor module tracks actual resource consumption and related
variation, reports performance, and assigns pathways to cases.
 
     The Reimbursement module calculates expected reimbursement.
 
     The DSS products are licensed under non-exclusive perpetual licenses. Total
client fees for DSS products range from $25,000 to $300,000, depending on the
size of the healthcare organization, and are comprised of license fees charged
for the specific modules that are licensed, along with implementation and
technical fees. At the time a license is granted, the Company generally enters
into a one-year maintenance and support agreement for an annual fee that is
typically based on a percentage of the then current license fee and which is
renewable at then current rates for successive one-year terms.

<PAGE>   125
 
  Patient Focused Systems (PFS)
 
     This division's main product is InterAct 2000, which is a modular system of
software tools and methodologies designed to manage patient care resource
utilization through workload measurement, staffing against budget, cost and
productivity reporting, and employee scheduling. As of May 31, 1997, PFS
software products were licensed to 450 healthcare organizations. InterAct 2000
includes two integrated modules:
 
     The Workload/Productivity module incorporates a proprietary, research-based
workload measurement methodology applicable to all medical/surgical, mental
health, ambulatory, perinatal, and dialysis populations. This module uses an
organization's own financial and quality of care objectives to generate
assessments of workload and staffing needs against the department's resource
utilization budget. Workload/Productivity tracks direct care provider costs so
managers can understand and control variances in revenue, expenses and
productivity. It also provides data for comparing and benchmarking resource
utilization relative to similar institutions or departments.
Workload/Productivity enables the user to fulfill JCAHO patient care resource
management requirements.
 
     The Personnel/Scheduler module creates balanced staff schedules based on a
specific scheduling algorithm and a set of user defined rules.
Personnel/Scheduler also maintains ongoing personnel records with available
interfaces to payroll and time and attendance systems.
 
     The PFS products are licensed under non-exclusive perpetual licenses. Total
client fees for PFS products range from $20,000 to $100,000, depending on the
size of the healthcare organization, and are comprised of license fees charged
for the specific modules that are licensed along with implementation and
technical fees. At the time a license is granted, Medicus generally enters into
a one-year maintenance and support agreement for an annual fee that is based on
a percentage of the then current license fee and which is renewable at then
current rates for successive one-year terms.
 
  Discontinued Operation
 
     Medicus formerly offered information management services to operate all or
part of the information systems division of selected healthcare provider
organizations. These services were generally performed on the client's premises
by Medicus personnel that functioned as though they were the client's employees.
 
     While the information systems management market presents several attractive
opportunities, it is dominated by many companies with significantly greater
financial and technical resources. As a result, price competition is strong and
sales cycles are traditionally much longer in this sector than in the Company's
core software and service product areas. Because of this, and the fact that
information systems management is not a strong fit with the Company's main focus
on healthcare decision support system opportunities, the Company decided to
discontinue this line of business. The Company will continue providing services
under its existing contract until May 31, 1998, the expiration date of the
contract.
 
  Maintenance and Support Services
 
     Medicus provides training and support services during client implementation
and thereafter, as required. Maintenance and support services include software
updates, enhancements and services which are purchased by substantially all of
the Company's clients under renewable annual contracts. The Company maintains
logging, notification, and follow-up procedures to track client problems
encountered in implementing and operating its products. It also conducts client
conferences to exchange ideas regarding product usage and product extensions.
Management believes that these conferences are valuable in gathering ideas for
future products as well as enhancements to the Company's current product line.
 
  Recurring Revenue
 
     The Company's recurring revenue (defined as revenue generated pursuant to a
multi-year contract or pursuant to an ongoing contract, such as the Company's
standard form of annual maintenance and technical support agreements, which
contemplate continued renewals) was $10.1 million, $9.4 million and $9.0 million
for the three fiscal years ended May 31, 1997, 1996 and 1995, respectively.
 
                                        5
<PAGE>   126
 
  Backlog
 
     As of May 31, 1997 and 1996, the Company's backlog (which consists of
signed contracts or purchase orders for products and services which are expected
to be realized as revenue over the next twelve months plus remaining revenue on
annual maintenance and support contracts) was approximately $9.2 million and
$8.1 million, respectively. Included in backlog is $4.2 million and $4.9 million
of deferred maintenance and support for the fiscal years ended May 31, 1997 and
1996, respectively.

     As healthcare delivery systems and their respective information systems
have become more integrated, the Company has also placed an increasing emphasis
on the integration of its products by implementing a strategy focused on
upgrading its client base to new versions of its software and cross-selling
additional products to its more than 1,200 existing customers. Because many of
these clients use only one or two of the Company's products, priced between
$15,000 and $300,000, the Company believes this strategy presents an excellent
growth opportunity.
 
  Market Environment
 
     The shift of patient care delivery to less costly settings, such as
outpatient clinics and physician offices, has accelerated the consolidation
trend of healthcare delivery organizations. Employers and government purchasers
of healthcare services have dramatically shifted providers' financial incentives
by capping expenditures through various contract pricing mechanisms.
Additionally, these consumers are devising new, objective indicators for
measuring clinical performance. Healthcare delivery organizations have responded
by radically restructuring care delivery processes. To support these delivery
process changes, providers need access to better data and more information
analysis tools.
 
     Successful healthcare organizations require new cost, profitability and
performance measurement systems to understand their patient populations and the
cost and outcomes of the care they provide. Market forces are significantly
altering the relationships among physicians, hospitals, employers and insurers
(private and government). New paradigms for care delivery, such as case
management, critical or clinical pathways and outcomes monitoring, require a
link between service costs and clinical outcomes. The demand for products such
as the Company's financial and clinical decision support products is growing
rapidly within the context of this increasingly competitive and price-sensitive
market.

  Competition
 
     The healthcare decision support software and services market is highly
competitive. The Company competes with several firms in each of its market
niches, although no one firm competes directly in all niches in which the
Company offers products. Competing firms vary in size and in geographic
coverage. A number of them have greater financial and management resources than
the Company. The Company believes that the principal factors affecting
competition are product functionality, analytical methodologies, flexibility and
ease of use, product enhancements, reliability and quality of implementation and
technical support, documentation, size of installed client base, competitive
pricing, and corporate reputation. The Company believes that it competes
favorably in these areas.
 
  Marketing and Sales
 
     Medicus sells its products through its own direct sales organization. The
Company's sales force has historically been organized along product lines but is
being reorganized to sell the full range of the Company's products. Individual
product sales are made by sales personnel and managers. Large sales
opportunities are pursued by a team including a corporate officer and sales and
technical personnel. The Company's products are also marketed under agreements
with accounting firms, consultants and hospital alliances.
 
     The Company establishes market presence by publishing articles, presenting
talks at professional meetings, assuming leadership positions in professional
organizations, participating in trade shows and advertising in trade magazines.
Prospective clients are identified through these and other methods including
direct mail, telemarketing, product seminars, and requests for proposals from
healthcare organizations.
 
  Technology
 
     The Company's software products, which operate on microcomputers in both a
standalone and network environment utilizing Windows NT, MS-DOS and UNIX
operating systems, are developed with the objective of providing efficient
operation, portability among mainstream hardware platforms and networks,
flexibility in supporting client needs, integrated modularity, and cost
effective support and enhancements. For this reason, VB, C, C++ and SmallTalk
programming languages are utilized for software development. Relational database
management systems for software products are SQL-compatible, with Oracle being
the Company's database system of choice. The support of industry standard
technologies as well as Company-developed proprietary development tools allow
effective and efficient product development and integration among current and
future products. The Company's experience with system interfaces and the
methodologies used for interfacing systems allows effective and rapid
connectivity of Company modules with other client systems.
 
  Product Development
 
     The software industry is characterized by rapid technological change and
the need for a continuing high level of expenditures for the development and
improvement of software products and services. Medicus' approach to designing
and developing successful products is market driven and based on working in
close collaboration with its clients. In developing its products, the Company
utilizes common software design and development tools and techniques.
 
     In order to maintain and improve the market acceptance of its products and
services, the Company believes it must maintain its commitment to product
development and enhancement. For the three fiscal years ended May 31, 1997, 1996
and 1995, the Company spent $4.6 million, $4.1 million and $4.1 million,
respectively, on research and development, representing 56%, 39% and 30% of
software products and services revenue. These expenditures include expensed,
capitalized and client-funded research and development spending.
 
     As of May 31, 1997, the Company employed 40 professional computer
programmers and technical personnel. Most of the Company's technical personnel
are involved, at different times and in varying degrees, in product development
and enhancement.

  Product Protection
 
     The Company owns various trademarks and servicemarks, including the
federally registered servicemark "Medicus." It does not own any patents or
registered copyrights. The Company believes that patent and copyright
protection, even if available, are less important in its industry than
innovative software engineering skills, technological and engineering experience
and marketing capabilities. The Company relies largely upon its license
agreements with clients and its own security systems, confidentiality procedures
and employee nondisclosure agreements to maintain the trade secrecy of its
products. While the enforceability of such agreements cannot be assured, the
Company believes that they provide a deterrent to unauthorized use of the
Company's proprietary information.
 
  Employees
 
     As of May 31, 1997, the Company employed 161 persons, of whom 65 were based
at the Company's Evanston, IL corporate offices, 45 were based at the Company's
Alameda, CA office, 16 were based at the Company's Chesterfield, MO office, and
35 were based at various other sales and service centers.
 
ITEM 2. PROPERTIES
 
     The Company's principal office is located in leased space in Evanston
containing approximately 23,200 square feet of space. The lease expires on June
30, 2006. The annual rent for fiscal 1998 for this space is $468,000.
 
     The Company also leases space for offices in Alameda, CA and Chesterfield,
MO. The leases for these two facilities expire on October 31, 1999 and April 30,
1998, respectively, and have an aggregate annual rent of $340,000 for fiscal
1998.
 
ITEM 3. LEGAL PROCEEDINGS
 
     On July 11, 1997, St. Joseph Hospital filed a lawsuit, St. Joseph Hospital
v. Medicus Systems Corporation, File No. 97-36574, in the District Court of
Harris County, Texas. The Company accepted service of the complaint on August
12, 1997. The complaint alleges primarily breach of a contract to provide case
management software, and seeks unspecified damages, including attorney's fees.
The Company vigorously denies any liability, and intends to file its answer
denying the plaintiff's claims prior to September 8, 1997, the date such answer
is due. The chief executive officers of the Company and the plaintiff have
recently met to discuss the matter.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     There were 185 holders of record and approximately 2,160 beneficial holders
of the Company's common stock as of August 21, 1997.
 
     The Predecessor Corporation (prior to March 1, 1996) and the Company
(beginning March 1, 1996) declared quarterly dividends of $0.03 per share in
each of the quarters in fiscal years 1995 and 1996. The Board of Directors of
the Company has determined not to pay dividends on the common stock for the
foreseeable future.
 
     On December 5, 1996, the Company reached an agreement in principle (the
"Agreement") with its founder, Richard C. Jelinek, to purchase from Mr. Jelinek
and a trust of which Mr. Jelinek is a beneficiary (the "Trust") one million
shares of Common Stock and 500 shares of Voting Preferred Stock. Also, Mr.
Jelinek agreed to resign as Chairman and agreed, among other things, not to
attempt to seek voting control of the Company for a period of five years. (Mr.
Jelinek continues to serve as a Director.) In exchange, the Company agreed to
pay Mr. Jelinek and the Trust $4.5 million in cash and $2.0 million in 8%
two-year promissory notes, and to issue to Mr. Jelinek and the Trust 400,000
five-year warrants to purchase Common Stock at $8.00 per share. The Company's
Board of Directors approved the Agreement on January 2, 1997, and the Company's
stockholders approved the Agreement at the Annual Meeting of Stockholders on
March 19, 1997. Neither the warrants nor the shares of Common Stock issuable
upon exercise of the warrants were registered under the Securities Act of 1933,
pursuant to the exemption contained in Section 4(2) of that Act.

(1) Shown as a percent of related revenues.
 
     Operating revenues are derived from two sources: (1) license fees and the
related services for licensing the Company's software products; and (2)
maintenance and support services related to such software products.
 
COMPARISON OF FISCAL YEAR 1997 TO FISCAL YEAR 1996
 
  Software Products and Services
 
     Software products and services revenues decreased 22% to $8.1 million in
fiscal 1997 compared to $10.4 million in fiscal 1996. The decrease in revenues
was attributable, in part, to the delay in the release of certain new
Windows-based products, including the next generation of Decision Support
Systems. Also contributing to the decline was a continued lengthening of the
sales cycle, due to complex implementation plans related to the increasing
number of clients migrating from the DOS-based to Windows-based products,
principally in the CDS division. Additionally, the Company experienced a
continuing weakness in its existing markets and product lines, resulting from
price pressures and consolidations in the healthcare industry and in the managed
care environment. Costs and expenses for software products and services
decreased 25% to $2.9 million compared to $3.9 million in fiscal 1996. Costs and
expenses as a percentage of related revenue
 
                                       11
<PAGE>   132
 
were 36% and 38% for fiscal 1997 and 1996, respectively. The decrease was due to
cost containment measures initiated by management and a lower volume of services
provided.
 
  Maintenance and Support Services
 
     Maintenance and support services revenues increased 7% to $10.1 million in
fiscal 1997 compared to $9.4 million in fiscal 1996. The increase was primarily
due to the continuing migration of clients to the Company's Windows-based
products, along with modest price increases for certain products. Costs and
expenses decreased 8% to $5.1 million in fiscal 1997 compared to $5.6 million in
fiscal 1996. Costs and expenses as a percentage of related revenue were 50% and
59% for fiscal 1997 and 1996, respectively. The decrease was primarily due to a
shift in focus of technical personnel from maintenance activities to development
activities to complete certain new Windows-based products.
 
  Marketing, General and Administrative
 
     Marketing, general and administrative expenses decreased 11% to $10.0
million in fiscal 1997 compared to $11.3 million in fiscal 1996. The decrease
primarily was due to higher expenses in the prior year related to the increase
in the provision for doubtful accounts, and expenses related to the separation
of the managed care business.
 
  Research and Development
 
     Total expenditures for research and development (including amounts
capitalized and funded by clients) increased 12% to $4.6 million in fiscal 1997
from $4.1 million in fiscal 1996. Research and development costs charged to
expense were $3.1 million in fiscal 1997 compared to $1.8 million in fiscal
1996. The Company did not obtain funding from clients under development service
agreements during the twelve months ended May 31, 1997, compared to $218,000
obtained in fiscal 1996, for its research and development efforts. These
development service agreements provide for retention of ownership of the
products developed by the Company. The Company capitalized software development
costs of $1.8 million in fiscal 1997 and $2.0 million in fiscal 1996 pursuant to
Statement of Financial Accounting Standards No. 86. Costs capitalized in fiscal
1997 were partially offset by $240,000 in provisions recorded as part of the
abandonment of certain development efforts. Total research and development
expenditures (including amounts capitalized and funded by clients) were 56% and
39% of software products and services revenues during fiscal 1997 and 1996,
respectively. During fiscal 1997, the Company's development efforts focused on
the Clinical Data Systems and Decision Support Systems product lines. During
fiscal 1996, the Company's development efforts focused on the Resource Case
Management System, Medicus Architecture (MACH 1), and the Decision Support
Systems product line.
 
  Restructuring Charges
 
     As part of an ongoing evaluation, the Company refined its strategic
planning process during fiscal 1997, and assessed continuing obligations
associated with the implementation of its strategic plan. The Company continued
the process of implementing its plans during 1997 and, following the stock
repurchase from its founder in the quarter ended February 28, 1997, recorded
$2.8 million in restructuring charges to complete its plan, including accruing
costs to reorganize the Company's business units, to abandon certain development
efforts, and to increase the allowance for doubtful accounts. Specifically, the
Company decided to relocate operations for its Clinical Data Systems ("CDS")
division, based in Alameda, CA, to the Company's Evanston, IL corporate offices.
Costs associated with the relocation, which is expected to be completed during
the next nine months, included costs to cancel existing lease agreements, to
terminate employees and to write down abandoned assets. The Company did not
accrue estimated incremental costs of approximately $1.3 million associated with
the relocation. Such costs relate to the orderly transition of the division,
will be incurred during fiscal 1998 and are not accruable as part of the
restructuring charge under generally accepted accounting principles. In
addition, the Company increased it reserves for product line exit costs and
severance costs that relate to the remaining customers of the previously
discontinued Clinical Case Management Systems ("CCM") product line. Also,
certain product development efforts for the Company's Patient
 
                                       12
<PAGE>   133
 
Focused Systems ("PFS") products were abandoned, and the associated development
costs, which had been previously capitalized, along with other related product
line exit costs were expensed. The Company has increased its allowance for
doubtful accounts due to the potential for certain additional billed and
unbilled accounts becoming uncollectible as a result of the decisions discussed
above. Direct costs and expenses of the restructuring were 15% of fiscal 1997
revenues.
 
  Stock Repurchase
 
     On December 5, 1996, the Company reached an agreement in principle (the
"Agreement") with its founder, Richard C. Jelinek, to purchase from Mr. Jelinek,
and a trust of which he is a beneficiary (the "Trust"), one million shares of
Common Stock and 500 shares of Voting Preferred Stock. Also, Mr. Jelinek agreed
to resign as Chairman and agreed, among other things, not to attempt to seek
voting control of the Company for a period of five years. In exchange, the
Company agreed to pay Mr. Jelinek and the Trust $4.5 million in cash and $2.0
million in 8% two-year promissory notes, and to issue to Mr. Jelinek and the
Trust 400,000 five-year warrants to purchase Common Stock at $8.00 per share.
 
     The Company's results of operations for the year ended May 31, 1997
included $1,690,042 in related costs and expenses, as a result of the Agreement.
Amounts in excess of the market price of the Common Stock and the exercise price
of the Voting Preferred Stock, aggregating $1,319,000, have been expensed. Also
included are $371,042 in investment banking and other professional fees incurred
to consummate the Agreement.
 
  Interest and Other Income
 
     Interest and other income decreased 34% to $367,000 in fiscal 1997 compared
to $556,000 in fiscal 1996, primarily due to lower average cash balances.
 
  Income Taxes
 
     The Company's effective income tax rate benefit decreased to 37% in fiscal
1997 compared to 41% in fiscal 1996. The decrease was primarily attributable to
the fiscal 1997 net operating loss and stock repurchase transaction.
 
  Discontinued Operation
 
     Results from the Company's discontinued line of business decreased 43% to
$199,000 in fiscal 1997 compared to $347,000 in fiscal 1996, primarily due to
lower revenues from the contract to manage the information systems functions at
Bethesda, Inc. in Cincinnati, Ohio.
 
COMPARISON OF FISCAL YEAR 1996 TO FISCAL YEAR 1995
 
  Software Products and Services
 
     Software products and services revenues decreased 23% to $10.4 million in
fiscal 1996 compared to $13.5 million in fiscal 1995. The decrease in revenue
was attributable, in part, to a general weakness in the Company's primary
markets and product lines, resulting from continued consolidations in the
healthcare industry and growing price pressures in the current managed
healthcare environment. Also contributing to the decline were delays in the
release of certain Windows-based products, higher than expected turnover in the
sales force, the increasing complexity and size of new contracts and the related
lengthening of the sales cycle. Additionally, the Company continued to
experience increased competition in many of its markets. Costs and expenses for
software products and services decreased 6% to $3.9 million compared to $4.1
million in fiscal 1995. Costs and expenses as a percentage of related revenue
were 38% and 31% for fiscal 1996 and 1995, respectively. The increase was due to
the mix of software, hardware and implementation revenue.
 
                                       13
<PAGE>   134
 
  Maintenance and Support Services
 
     Maintenance and support services revenues increased 5% to $9.4 million in
fiscal 1996 compared to $9.0 million in fiscal 1995. The increase was primarily
due to a larger installed base of licensed products and modest price increases
for the Company's maintenance and support services. Costs and expenses increased
27% to $5.6 million compared to $4.4 million in fiscal 1995. Costs and expenses
as a percentage of related revenue were 59% and 49% for fiscal 1996 and 1995,
respectively. The increase was primarily due to a shift in focus of technical
personnel to maintenance activities from development activities during fiscal
1996, and incremental expenses related to supporting clients on the Company's
new Windows-based products as well as the technology platforms historically
support by the Company.
 
  Marketing, General and Administrative
 
     Marketing, general and administrative expenses increased 36% to $11.3
million in fiscal 1996 compared to $8.3 million in fiscal 1995. The increase
primarily resulted from an increase in the provision for doubtful accounts,
following a comprehensive analysis necessitated by the current market conditions
in the healthcare industry, and expenses related to the separation of the
managed care business.
 
  Research and Development
 
     Total expenditures for research and development (including amounts
capitalized and funded by clients) remained constant at $4.1 million in fiscal
1996 and 1995. Research and development costs charged to expense were $1.8
million in fiscal 1996 compared to $2.2 million in fiscal 1995. The Company
obtained funding from clients under product development service agreements of
$218,000 and $509,000 in fiscal 1996 and 1995, respectively, for its research
and development efforts. These development service agreements provide for
retention of ownership of the products developed by the Company. The Company
capitalized software development costs of $2.0 million in fiscal 1996 and $1.4
million in fiscal 1995 pursuant to Statement of Financial Accounting Standards
No. 86. Total research and development expenditures (including amounts
capitalized and funded by clients) were 39% and 30% of software products and
services revenues during fiscal 1996 and 1995, respectively. During fiscal 1996,
the Company's development efforts focused on the Resource Case Management
System, Medicus Architecture (MACH 1), and the Decision Support Systems product
line. During fiscal 1995, the Company's development efforts focused on the
Clinical Case Management System, the Resource Case Management System, the
WinCoder+ and Workload/Productivity modules.
 
  Restructuring Charges
 
     During February, 1996, the Company commenced a process to evaluate its
current strategic position, including the markets it expects to pursue and its
product offerings in those chosen markets. As a result of decisions made as part
of this evaluation process, the Company recorded $4.7 million in restructuring
charges, representing costs and expenses to exit certain product lines, to
abandon certain product development efforts and to provide for liabilities
resulting from the strategic redirection of the Company, including severance
costs. Specifically, the Company decided to exit the Clinical Case Management
Systems and the Executive Information Systems product lines. Additionally,
product development efforts for the Clinical Data Systems Wincoder V2 project
and portions of the MACH 1 project, which will no longer be utilized in the
Medicus product line, were abandoned and their associated development costs,
which had been previously capitalized, were expensed. Severance costs associated
with an officer and several employees, in addition to the write-off of a portion
of the Contract Management System, were also included in the restructuring
charge. Direct costs and expenses of the restructuring were 24% of fiscal 1996
revenues.
 
  Interest and Other Income
 
     Interest and other income decreased 18% to $556,000 in fiscal 1996 compared
to $680,000 in fiscal 1995, primarily due to lower average cash balances.
 
                                       14
<PAGE>   135
 
  Income Taxes
 
     The Company's effective income tax rate increased to 41% in fiscal 1996
compared to 36% in fiscal 1995. The increase was primarily attributable to the
fiscal 1996 suspension of the research and development tax credit.
 
  Discontinued Operation
 
     Results from the Company's discontinued line of business increased 7% to
$347,000 in fiscal 1996 compared to $324,000 in fiscal 1995, primarily due to
higher revenues from the contract to manage the information systems functions at
Bethesda, Inc. in Cincinnati, Ohio.
 
FINANCIAL CONDITION
 
  Liquidity and Capital Resources
 
     As a result of the Company's commitment to expand its software products and
services, funds are required to support its ongoing product research and
development activities and the infrastructure required to serve its customer
base. Historically, cash generated from its operations has been an important
contributor to these needs. As a result of the market factors adversely
affecting fiscal 1997 results, as well as the stock repurchase transaction, the
Company was required to use a significant portion of its cash reserves. It is
expected that, following the restructuring efforts described herein, the Company
will return to a situation where cash from operations will provide an important
source of liquidity to support its normal capital needs, although numerous
factors, including any reductions in revenues from currently anticipated
amounts, could affect the amount of such cash available.
 
     At May 31, 1997, the Company had available cash reserves of approximately
$1.2 million. In addition, the Company had a $2.5 million standby credit
facility available. $1.0 million of the principal amount of the Company's 8%
promissory notes, issued in connection with the Company's stock repurchase
agreement, is due in March 1998. In addition, the Company anticipates cash
outlays of approximately $3.2 million in the next nine months, resulting
primarily from its decision to reorganize its business units and to exit certain
product lines.
 
     The Board of Directors of the Company has determined not to pay dividends
on the common stock for the foreseeable future. While the Company has
experienced negative cash flows from operating activities during the past two
fiscal years, management believes that, as a result of significant reductions in
expenses, its cash flows will improve. While there can be no assurance that this
will occur, the Company currently believes that it will have adequate financial
resources available from operations and the available credit facility to provide
sufficient liquidity to meet its ordinary capital requirements for the
foreseeable future, including the March 1998 payment on the promissory notes and
cash outlays related to the Company's restructuring plan.
 
     During its second fiscal quarter, the Company bills its clients in advance
for the next calendar year's maintenance and support services provided on its
software products. This generates an increase in the Company's accounts
receivable and deferred revenue balances during those periods, and increases
cash balances in subsequent months as the related accounts receivable are
collected.
 
  Impact of Inflation
 
     To date, inflation has not had a material impact on the Company's revenues
or income.

conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on

believe that our audits provide a reasonable basis for the opinion expressed
above.

                         NOTES TO FINANCIAL STATEMENTS
NOTE 1. GENERAL INFORMATION AND BASIS OF PRESENTATION
 
     Prior to March 1, 1996, the Company's predecessor (the "Predecessor
Corporation") operated a software and related services business and a small
managed care business. In connection with a series of transactions which
occurred on March 1, 1996, the Predecessor Corporation formed a new Delaware
subsidiary, Medicus Systems Software, Inc., to which it transferred all of its
assets and liabilities excluding only the defined assets and liabilities of its
managed care business. In turn, the stock of this newly-formed subsidiary was
distributed on a share-for-share basis to the stockholders of the Predecessor
Corporation (the "Distribution"), the name of the subsidiary was changed to
Medicus Systems Corporation (the "Company"), and the name of the Predecessor
Corporation was changed to Managed Care Solutions, Inc. ("MCS"). The Company is
liable for all obligations of the Predecessor Corporation except those
specifically related to the Predecessor Corporation's managed care business.
 
     Although the Company is, in substance, the Predecessor Corporation's
successor, the financial statements of the Company have been prepared as if the
Company had operated as a free-standing entity for all the periods presented
(excluding certain incremental corporate expenses that would have been incurred
had it operated on a stand-alone basis). Accordingly, the financial statements
include those assets, liabilities, revenues and expenses directly attributable
to the Company's operations and exclude those specifically related to the
managed care business. The Company believes this presentation most fairly
represents its financial condition, results of operations and changes in
stockholders' equity and cash flows. The financial statements included herein
for periods prior to the Distribution do not necessarily reflect what the
financial position and results of operations of the Company would have been had
it operated as a stand-alone entity during the periods covered, and may not be
indicative of future operations or financial position.
 
     The Company and MCS signed a services agreement, pursuant to which the
Company (i) made available to MCS certain services, including tax, accounting,
data processing, cash management, employee benefits, monitoring, operational,
supervisory, insurance purchasing and claims administration consulting services,
and (ii) provided certain financial services to MCS, including analysis and
advice regarding potential financial transactions (including but not limited to
proposed issuance of debt or equity securities, proposed merger or asset
acquisition or sale transactions and dividend, stock split or similar
transactions), assistance in budget and forecast preparation, relations with
financial analysts, financial press, and investors, and crisis management and
control. Such services commenced on March 1, 1996, and continued for one year.
MCS paid the Company $700,000 for such services. In order to compensate the
Company for fixed costs incurred in making such services available, MCS paid
such fees whether or not it elected to utilize the services. MCS also reimbursed
the Company for its out-of-pocket expenses in connection therewith. The services
agreement also provided that the Company would not be liable for any losses or
damages suffered in respect of services to be performed thereunder, other than
by reason of its willful misconduct or gross negligence in performing such
services. Marketing, general and administrative expenses were reduced by
$525,000 and $175,000 in the years ended May 31, 1997 and 1996, respectively, as
a result of this agreement.
 
NOTE 2. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of operations
 
     Medicus develops, markets, and supports a family of specialized integrated
software products utilized by healthcare financial administrators, physicians
and nursing executives, health information and other administrative departments
in the United States and Canada. The Company's software products and services
enable clients to capture, structure and analyze clinical, operational and
financial information thereby allowing these professionals to measure, monitor
and manage organizational performance and optimize outcomes. Medicus also
provides product-related maintenance and support services.

                          MEDICUS SYSTEMS CORPORATION
 
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
  Revenue recognition
 
     Revenue from software license agreements is recognized upon contract
execution, product delivery and client acceptance in instances where no
remaining obligations under the agreement exist. In instances where minor
obligations remain under a license agreement after the delivery of the product,
a pro rata portion of the revenue is deferred until the minor obligations have
been fulfilled. When the software product has been delivered but significant
obligations are present under a license agreement, the full amount of revenue
under the agreement is deferred and recognized as the related services are
performed. Revenue from maintenance and support agreements is recognized ratably
over the term of the contract.
 
  Inventories
 
     Inventories, which consist primarily of data processing equipment and
forms, are stated at the lower of cost or market value, cost being determined
using specific identification.
 
  Property and equipment
 
     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method based upon an estimated useful life of five years.
Gains or losses resulting from sales or retirements are recorded as incurred, at
which time related costs and accumulated depreciation are removed from the
accounts. Renewals and betterments are capitalized and depreciated. Maintenance
and repairs are charged to expense as incurred.
 
     Purchased software used in operations is stated at cost. Amortization is
computed using the straight-line method based upon an estimated useful life of
three to five years. The amortization charged to expense in 1997, 1996 and 1995
totaled $305,415, $371,095 and $315,313, respectively.
 
  Internally developed software
 
     Costs of internally developed software (net of accumulated amortization)
aggregating $3,087,849 and $2,152,419 as of May 31, 1997 and 1996, respectively,
consist of certain production costs of computer software to be sold, leased or
otherwise marketed which have been capitalized in accordance with the provisions
of Statement of Financial Accounting Standards ("SFAS") No. 86. Capitalized
software costs are amortized on a product-by-product basis. Amortization is
computed based upon the ratio of current revenues to total anticipated revenues
or the straight-line method over the estimated life of the product (typically
three years), whichever provides the greater amortization. Amortization expense
for capitalized software costs totaled $381,237, $784,209 and $222,595 during
1997, 1996 and 1995, respectively.
 
  Research and development
 
     Research and development costs, principally the design and development of
proprietary software prior to the establishment of technological feasibility,
are expensed as incurred. Routine maintenance expenses incurred in connection
with specific software applications related to individual contracts are charged
to costs of software products and services as incurred.
 
  Income taxes
 
     The Company follows the provisions of Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes." The statement requires an
asset and liability approach for financial accounting and reporting for income
taxes.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
  Earnings per share
 
     Since the capital structure of the Company is comparable to that existing
prior to the Distribution, earnings (loss) per common share is based upon the
actual capital structure of the Company for the period from March 1, 1996
through May 31, 1997, and the capital structure of the Predecessor Corporation
for the period from June 1, 1995 through February 29, 1996. Pro forma earnings
(loss) per common share is based upon the capital structure of the Predecessor
Corporation, and does not necessarily reflect the results of operations of the
Company had it operated as a stand-alone entity during the periods presented,
and may not be indicative of future operations. Weighted average shares used in
the calculation of earnings (loss) per share represent common stock and common
stock equivalents. Common stock equivalents include shares issuable on the
exercise of stock options and the warrant (when dilutive), using the treasury
stock method from the date of grant.
 
  Management estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses recognized during the periods presented. Actual results could differ
from those estimates.
 
  Fair value of financial instruments
 
     The carrying amounts reported in the balance sheets for cash, short-term
investments, accounts receivable, prepaid expenses and other current assets,
accounts payable, accrued expenses and notes payable approximate fair value
because of the immediate or short-term maturity of these financial instruments.
 
  Statements of cash flows
 
     For purposes of the Statements of Cash Flows, the Company considers cash
and cash equivalents to be cash and overnight investments. Actual cash paid for
income taxes for the years ended May 31, 1997, 1996 and 1995 was $90,561,
$539,559 and $1,427,700, respectively.
 
  Reclassifications
 
     Certain reclassifications have been made in the prior period financial
statements to conform to the current period presentation. These
reclassifications had no effect on previously reported total assets, total
liabilities, stockholders' equity or results of operations.
 
NOTE 3. DISCONTINUED OPERATION
 
     Effective May 31, 1997 the Company adopted a plan to discontinue its
contract services line of business. This separate line of business consisted of
information systems management contracts with two customers (one customer during
the year ended May 31, 1997). As a result of this decision, the net assets of
the contract services line of business have been reclassified in the Balance
Sheet at May 31, 1997 and 1996. Also, the results of operations of the contract
services business have been reclassified in the Statements of Operations for the
three years ended May 31, 1997.

NOTE 4. RESTRUCTURING CHARGES
 
     During the third quarter of fiscal 1996, the Company commenced a process to
evaluate its strategic position, including the markets it will pursue and
product offerings in those chosen markets. As a result of decisions made in the
quarter ended February 29, 1996, the Company began a plan resulting in the
recording of approximately $1.6 million in charges to exit certain product lines
and abandon certain development efforts.
 
     Specifically, the Company decided to exit the Executive Information Systems
product line, recording charges to write down related customer accounts and
accrue future costs to provide maintenance associated with existing contractual
obligations. In addition, product development efforts for the Optimizer project
and portions of the MACH 1 project, which will no longer be utilized in the
Medicus product line, were abandoned and their associated development costs,
which had been previously capitalized, were expensed.
 
     During the fourth quarter of fiscal year 1996, the Company continued the
process resulting in additional charges of $3.1 million. The Company decided to
exit the Clinical Case Management Systems product line and abandon development
efforts for the Clinical Data Systems Wincoder V2 project. Severance costs
associated with an officer and several employees, in addition to the write-off
of a portion of the Contract Management System, were also included in the
restructuring charge.
 
     As part of an ongoing evaluation, the Company refined its strategic
planning process during fiscal 1997, and assessed continuing obligations
associated with the implementation of the plan. The Company continued the
process of implementing its plans during 1997 and, following the stock
repurchase from its founder in the quarter ended February 28, 1997, recorded
$2.8 million in charges to complete its plan, including accruing certain costs
to reorganize the Company's business units, to abandon certain development
efforts, and to increase the allowance for doubtful accounts. Specifically, the
Company decided to relocate operations for its Clinical Data Systems ("CDS")
division, based in Alameda, CA, to the Company's Evanston, IL corporate offices.
Costs accrued associated with the relocation, which is expected to be completed
during the next twelve months, included costs to cancel existing lease
agreements, to terminate employees and to write down abandoned assets. In
addition, the Company increased its reserves for product line exit costs and
severance

costs that relate to the remaining customer of the previously discontinued
Clinical Case Management Systems ("CCM") product line. Also, certain product
development efforts for the Company's Patient Focused Systems ("PFS") products
were abandoned, and the associated development costs, which had been previously
capitalized, along with other related product line exit costs were expensed. The
Company has increased its allowance for doubtful accounts due to the potential
for certain additional billed and unbilled accounts to become uncollectible as a
result of the decisions discussed above.
 
     The restructuring charges included in the Statements of Operations for the
years ended May 31, 1997 and May 31, 1996, respectively, were comprised of the
following items:

     The Company's revised strategic plan included the termination of three
officers and thirty-nine employees in 1997 and one officer and three employees
in 1996.
 
     At May 31, 1996, restructuring liabilities in the Balance Sheet aggregated
$1,527,461. During the year ended May 31, 1997, the Company increased its
reserve for employee termination and severance costs and product line exits
costs by $569,868 and $798,000, respectively, primarily due to the Company's
decision to relocate its CDS division and increase its CCM product line reserve.
The Company also recorded a $705,697 charge for business unit reorganization
costs associated with the relocation. The Company did not accrue estimated
incremental costs of approximately $1.3 million associated with the relocation.
Such costs relate to the orderly transition of the division, will be incurred
during fiscal 1998 and are not accruable as part of the restructuring charge
under generally accepted accounting principles. During the year ended May 31,
1997 the Company paid $763,844, $233,950 and $31,100 in severance benefits,
product line exit costs, and business unit reorganization costs, respectively.
The Company also reduced its reserve for severance obligations and continuing
obligations on product line exit costs by $124,716 and $200,000, respectively,
as a result of favorable settlements with two of its employees and negotiations
with its customers.
 
     The components of the restructuring reserve at May 31, 1997, which the
Company expects will be paid during the next twelve months, and at May 31, 1996
are as follows:

     In connection with the Distribution, the Company and MCS agreed to share
the tax burdens of the Predecessor Corporation, based upon the taxable income of
the separate businesses prior to the Distribution. The Company and MCS are also
prohibited from taking any actions which are inconsistent with the tax-free
nature of the Distribution.
 
     The Company will be able to utilize tax net operating losses incurred
subsequent to the Distribution to the extent the Company has taxable income
subsequent to the Distribution.
 
     Management has determined that the net deferred tax asset more likely than
not will be realized in the future and, therefore, has not provided any
valuation allowances against these assets. The Company's net operating loss
carryforwards of $3,544,223 expire in 2011 and 2012, while research and
development tax credits expire in 2012.

security interest in all assets of the Company. Certain financial covenants and
reporting requirements are also included in the agreement. As of May 31, 1997,
the Company had not utilized the line of credit.

     The previous chairman of the board and chief executive officer exercised an
option to purchase all of the authorized and unissued shares of voting preferred
stock at $1,000 per share on March 19, 1997. The Company, as part of the stock
repurchase agreement, immediately repurchased these shares. The voting preferred
stock is currently held in treasury.
 
     The Board of Directors has the authority to determine the rights and
preferences of this preferred stock upon its issuance.
 
NOTE 10. STOCK OPTIONS AND WARRANTS
 
     Upon the Distribution, the Company adopted various stock option plans of
the Predecessor Corporation. Options to purchase Predecessor Corporation common
stock have been converted into options to purchase Medicus common stock based
upon the fair market value following the Distribution. The Company applies APB
Opinion 25 and related Interpretations to account for its plans. Accordingly, no
compensation cost is generally recognized for its stock option plans and its
employee stock purchase plan. Had compensation cost for the Company's
stock-based compensation plans been determined based on the fair value at the
grant dates for awards under those plans consistent with the method prescribed
by SFAS 123, "Accounting for Stock-Based Compensation," the Company's net income
and earnings per share would have been reduced to the pro forma amounts
indicated below:

     For purposes of SFAS 123, the fair value of each option grant is estimated
on the date of grant using the Black-Scholes option-pricing model with the
following weighted-average assumptions used for grants in 1997 and 1996
respectively: no expected dividends, expected volatility of and 76.36% and
72.17%, risk-free interest rates of 6.56% and 6.09% for the stock options; and
lives of 7 years. The weighted-average fair value of options granted in 1997 and
1996 was $4.18 and $5.30 respectively.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
     The stock exercise price of each option is determined by a committee (the
"Committee") of no fewer than two Directors designated by the Board of
Directors, and shall not be less than the fair market value of the stock subject
to the option at the time the option is granted. Each option shall be for such
term of not more than ten years as shall be determined by the Committee at the
date of grant. The Committee shall have full and final authority, in its
absolute discretion, to determine the time or times when each option becomes
exercisable and the duration of the exercise period. The Committee may at its
discretion accelerate the exercisability of any option at any time before
expiration or termination of an option previously granted, extend the terms of
such option, except that an aggregate option period may never exceed ten years.
 
     As of May 31, 1997, the Company had 358,879 options available for grant
under all plans. A summary of the status of the Company's option plans as of May
31, 1997 and 1996, and changes during the years then ended is presented below:

NOTE 11. EMPLOYEE BENEFITS
 
     In connection with the Distribution, the Company adopted an employee stock
purchase plan under which the sale of common stock to employees was authorized.
Employees may designate up to the lesser of $10,000 or 10% of their compensation
for the purchase of stock. The purchase price is the lesser of 85% of the fair
market value of the stock on either the date of grant of a one-year purchase
option or the date the purchase option is exercised. During the year ended May
31, 1997 and the period from March 1, 1996 through May 31, 1996, 29,162 and
7,132 shares, respectively, of common stock were issued under the plan for an
aggregate purchase price of $128,423 and $38,352, respectively. Compensation
cost related to the employee stock purchase plan, as determined based on the
fair value method of SFAS 123, would have aggregated $139,000 and $75,000,
respectively, for the years ended May 31, 1997 and 1996 had the Company adopted
this statement. For purposes of SFAS 123, these amounts were estimated using the
Black-Scholes model with the following assumptions for the years ended May 31,
1997 and 1996, respectively: no expected dividends, an expected life of one
year, expected volatility of 130.17% and 158.17% and risk-free interest rates of
5.40% and 5.45%.
 
     The Company has a contributory retirement savings plan ("401(k) Plan")
which covers eligible employees who qualify as to age and length of service.
Participants may contribute 1% - 15% of their salaries, subject to maximum
contribution limitations imposed by the IRS. The expense of the 401(k) Plan,
consisting of discretionary Company contributions, was $134,795, $121,602 and
$101,512 for the years ended May 31, 1997, 1996 and 1995, respectively.
 
NOTE 12. COMMITMENTS
 
     The Company has various lease agreements for real and personal property.

     Rental expense on all operating leases totaled $828,221, $682,400, and
$664,844, during fiscal 1997, 1996 and 1995, respectively.
 
NOTE 13. RELATED PARTY TRANSACTIONS
 
     As discussed in Note 1, the Company and MCS signed a services agreement.
For the year ended May 31, 1997 and during the fourth quarter of fiscal 1996,
the Company charged MCS $525,000 and $175,000, respectively, for services under
this agreement, reducing general and administrative expense by these amounts.
Due from Managed Care Solutions, Inc. on the Balance Sheet includes this charge
plus amounts owing related to the Distribution. During fiscal 1996 and 1995, the
Company provided MCS cash infusions for operating purposes of $250,000 and
$5,000,000, respectively.
 
     The Company has repurchased Common Stock and Voting Preferred Stock from
its founder, Richard C. Jelinek, and a trust of which he is a beneficiary,
pursuant to a transaction described in Note 5 and Note 8. Mr. Jelinek continues
to serve as a Director.

NOTE 14. CONCENTRATIONS OF CREDIT RISK
 
     The Company's revenues are generated from clients operating in the
healthcare industry, and accordingly, as of May 31, 1997 and 1996, all of the
Company's trade receivables and installment receivables were from entities in
this industry. The Company has no policy requiring collateral for the extension
of trade credit in the ordinary course of business.
 
NOTE 15.  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     SFAS No. 128, "Earnings per Share," issued in February 1997, changes the
method of calculating earnings per share and will be effective for the Company's
financial statements for the year ending May 31, 1998. Earlier application is
not permitted. However, the Company is permitted to disclose pro forma earnings
per share amounts computed using this Statement in periods prior to adoption.
Upon adoption, all prior period earnings per share data presented shall be
restated to conform to this Statement. The calculation of earnings per share
under this Statement is simpler than prior methods and more consistent with
international accounting standards. Given the Company's historical losses,
common stock equivalents were excluded from prior pro forma earnings per share
calculations because they were anti-dilutive. Therefore, adoption of this
Statement is not expected to have a material impact on amounts previously
reported as pro forma net loss per common share.
 
     SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997,will
require the Company to disclose, in financial statement format, all non-owner
changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments, certain minimum pension liabilities and
unrealized gains and losses on available-for-sale securities. This Statement is
effective for fiscal years beginning after December 15, 1997 and requires
presentation of prior period financial statements for comparability purposes.
The Company expects to adopt this Statement beginning with its financial
statements for the year ending May 31, 1998.
 
     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and interim
financial reports. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. Operating segments
are components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in assessing performance. Generally,
financial information is required to be reported on the basis that is used
internally for evaluating segment performance and deciding how to allocate
resources to segments. The Company expects to adopt this Statement in its
financial statements for the year ending May 31, 1998.

                                  ARTICLE TWO
 
                                     LOANS
 
     SECTION 2.1. Loan Amount. Subject to the terms and conditions of this
Agreement, on the date upon which all of the terms and conditions of the
Documents have been met or fulfilled to the satisfaction of Lender (the "Closing
Date"), the Lender agrees to make loans in the aggregate to the Borrower on a
revolving basis (such loans being herein called individually a "Revolving Loan"
and collectively the "Revolving Loans") from time to time in such amounts as the
Borrower may from time to time request up to the maximum amount of $2,500,000.00
(the "Line of Credit"); provided, however, that (A) repayments from time to time
of the Line of Credit shall be available to be reborrowed pursuant to the terms
and conditions of this Agreement; and (B) if the Revolving Loans outstanding at
any time or from time to time exceeds the advance limitations described above,
Borrower shall pay on demand to the Lender such amount necessary to eliminate
such excess; and (C) the Lender's commitment to make Revolving Loans shall
remain in effect for a period to and including October 10, 1999 (the "Revolver
Termination Date"); and (5) notwithstanding anything else contained in this
Agreement, (i) upon the occurrence and continuance of any Event of Default, and
in every such event, the Lender may, in its sole discretion, immediately cease
to make Revolving Loans; and (ii) Borrower shall repay to the Lender on the
Revolver Termination Date all Revolving Loans, plus interest accrued to the date
of payment.
 
     SECTION 2.2. Use of Loan Proceeds. The proceeds of any borrowing by the
Borrower pursuant to the Revolving Loans shall be used by the Borrower solely
for refinancing existing indebtedness of the Borrower, providing working capital
for Borrower and paying for operating expenses of the Borrower and the fees,
costs and expenses of the Lender as provided for in this Agreement.
 
     SECTION 2.3. Revolving Note.
 
     (A) General. The Revolving Loans shall be evidenced by a promissory note
(herein called the "Revolving Note") in form and manner satisfactory to Lender,
dated the date first above written, payable to the order of the Lender, in the
principal amount of the Maximum Line of Credit Amount. The date and amount of
each Revolving Loan made by the Lender and of each repayment of principal
thereon received by the Lender shall be recorded by the Lender in the records of
the Lender and the aggregate unpaid principal
 
                                        4
<PAGE>   166
 
amount shown on such records shall be rebuttable, presumptive evidence of the
principal owing and unpaid on the Revolving Note. The failure to record any such
amount on such records shall not, however, limit or otherwise affect the
obligations of the Borrower hereunder or under the Revolving Note to repay the
principal amount of the Revolving Loans together with all interest accruing
thereon. The unpaid principal amount from time to time outstanding on the
Revolving Loans shall be payable as set forth in the Revolving Note. Lender is
hereby authorized to debit any of the Borrower' accounts with Lender and/or make
a Revolving Loan with the proceeds disbursed directly to Lender to make the
required payments pursuant to this Section.
 
     (B) Interest Rate Options.
 
     (i) Interest Rate Option Conditions Not Met. Unless and until all of the
Interest Rate Option Conditions shall have been met, the unpaid principal amount
of the Revolving Note shall only bear interest at the Prime Rate, as in effect
from time to time; provided, however, that upon the occurrence of any Event of
Default, the unpaid amounts due and owing pursuant to the Revolving Note shall
bear interest, whether before or after judgment, until payment in full thereof
at the rate per annum determined by adding 4% to the interest rate which would
otherwise be applicable thereto from time to time. Any change in the interest
rate on the Revolving Note resulting from a change in the Prime Rate shall be
and become effective as of and on the date of the relevant change in the Prime
Rate. Interest accruing pursuant to this clause (i) shall be due and payable on
the first day of each month.
 
     (ii) Interest Rate Option Conditions Met. Commencing with the date on which
all of the Interest Rate Option Conditions shall have been met, the unpaid
principal amount of the Revolving Note shall bear interest as described in this
Section 2.3(B)(ii).
 
     (a) Option. Subject to all of the terms and conditions of this Agreement,
commencing with the date on which all of the Interest Rate Option Conditions
shall have been met, portions of the principal indebtedness evidenced by the
Revolving Note (all of the indebtedness evidenced by the Revolving Note bearing
interest at the same rate for the same period of time being hereinafter referred
to as a "Portion") may, at the option of Borrower, bear interest with reference
to the Prime Rate (the "Prime Rate Portion") or with reference to the Libor
(individually, a "Libor Portion" and collectively, the Libor Portions") and
Portions may be converted at the option of Borrower from time to time from one
basis to another. All of the indebtedness evidenced by the Revolving Note which
is not part of a Libor Portion shall constitute a single Prime Rate Portion. All
of the indebtedness evidenced by the Revolving Note which bears interest with
reference to a particular Libor for a particular Interest Period shall
constitute a single Libor Portion.
 
     (b) Prime Rate Portion. The Prime Rate Portion shall bear interest at the
Prime Rate as in effect from time to time, minus (I)  1/4% unless and until all
of the Interest Rate Reduction Conditions shall have been met; and (II)  1/2%
commencing with the date on which all of the Interest Rate Reduction Conditions
shall have been met; provided, however, that upon the occurrence of any Event of
Default, such Portion shall bear interest, whether before or after judgment,
until payment in full thereof at the rate per annum determined by adding 4% to
the interest rate which would otherwise be applicable thereto from time to time.
Any change in the interest rate on the Prime Rate Portion resulting from a
change in the Prime Rate shall be and become effective as of and on the date of
the relevant change in the Prime Rate. Interest on the Prime Rate Portion shall
be due and payable on the first day of each month.
 
     (c) Libor Portions. Each Libor Portion shall bear interest for each
Interest Period selected therefor at a rate per annum determined by adding (I)
2.25% unless and until all of the Interest Rate Reduction Conditions shall have
been met to Libor for such Interest Period; and (II) 2.00% commencing with the
date on which all of the Interest Rate Reduction Conditions shall have been met
to Libor for such Interest Period, provided, however, that upon the occurrence
of any Event of Default such Portion shall bear interest, whether before or
after judgment, until payment in full thereof through the end of the Interest
Period then applicable thereto at the rate per annum determined by adding 4% to
the interest rate which would otherwise be applicable thereto, and effective at
the end of such Interest Period such Libor Portion shall automatically be
converted into and added to the Prime Rate Portion and shall thereafter bear
interest at the interest rate applicable to the Prime Rate Portion after the
occurrence of an Event Default. At any time and from time to time, Borrower may
identify no more than 5 Libor Portions of the outstanding principal balance of
the Line of Credit. Each Libor
 
                                        5
<PAGE>   167
 
Portion shall be in a minimum amount of $250,000.00. Interest on each Libor
Portion shall be due and payable on the last day of each Interest Period
applicable thereto and at maturity (whether by lapse of time, acceleration or
otherwise) and, with respect to any Interest Period applicable to a Libor
Portion in excess of three (3) months, then on the date occurring every three
(3) months after the date such Interest Period began and at the end of such
Interest Period, and interest after maturity shall be due and payable upon
demand. Borrower shall notify Lender on or before 9:00 a.m. (Chicago time) on
the third Business Day preceding the end of an Interest Period applicable to a
Libor Portion whether such Libor Portion is to continue as a Libor Portion, in
which event Borrower shall notify Lender of the new Interest Period selected
therefor, and in the event Borrower shall fail to so notify Lender, such Libor
Portion shall automatically be converted into and added to the Prime Rate
Portion as of and on the last day of such Interest Period. Anything contained
herein to the contrary notwithstanding, the obligation of Lender to create,
continue or effect by conversion any Libor Portion shall be conditioned upon the
fact that at the time no Event of Default shall have occurred and be continuing.
 
     (C) Manner of Option Rate Selection for Revolving Note. Borrower shall
notify Lender (i) by 9:00 a.m. (Chicago time) at least three (3) Business Days
prior to the date upon which it requests that any Libor Portion be created or
that any part of the Prime Rate Portion be converted into a Libor Portion, (each
such notice to specify in each instance the amount thereof and the Interest
Period selected therefor); and (ii) by 1:30 p.m. (Chicago time) on the Business
Day upon which it requests that any Prime Rate Portion be created. If any
request is made to convert a Libor Portion into a Prime Rate Portion available
hereunder, such conversion shall only be made so as to become effective as of
the last day of the Interest Period applicable thereto. All requests for the
creation, continuance or conversion of Portions under this Agreement shall be
irrevocable. Such requests may be written or oral and Lender is hereby
authorized to honor telephonic requests for creations, continuances and
conversions received by it from any person Lender in good faith believes to be a
person authorized to act on behalf of Borrower hereunder, Borrower hereby
indemnifying Lender from any liability or loss ensuing from so acting. Each
determination of Libor made by Lender shall be conclusive and binding absent
manifest error.
 
     (D) Change of Law. Notwithstanding any other provisions of the Documents,
if at any time Lender shall determine in good faith that any change in
applicable laws, treaties or regulations or in the interpretation thereof makes
it unlawful for Lender to create or continue to maintain any Libor Portion, it
shall promptly so notify Borrower and the obligation of Lender to create,
continue or maintain such Libor Portion under this Agreement shall terminate
until it is no longer unlawful for Lender to create, continue or maintain such
Libor Portion. Borrower, on demand, shall, if the continued maintenance of any
Libor Portion is unlawful, at its option, either (i) thereupon prepay the
outstanding principal amount of the affected Libor Portion, together with all
interest accrued thereon and all other amounts payable to Lender with respect
thereto under this Agreement; or (ii) convert the principal amount of the
affected Portion into the Prime Rate Portion available hereunder, subject to the
terms and conditions of this Agreement.
 
     (E) Unavailability of Deposits or Inability to Ascertain
Libor. Notwithstanding any other provision of this Agreement or of the Revolving
Note, if prior to the commencement of any Interest Period, Lender shall
determine that deposits in the amount of any Libor Portion scheduled to be
outstanding during such Interest Period are not readily available to Lender in
the relevant market or by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining Libor, then Lender
shall promptly give notice thereof to Borrower and the obligations of Lender to
create, continue or effect by conversion any Libor Portion in such amount and
for such Interest Period shall terminate and the interest rate on the Revolving
Note shall be converted into a Prime Rate Portion; provided, however, that when
deposits in such amount and for the Interest Period selected by Borrower shall
again be readily available in the relevant market and adequate and reasonable
means exist for ascertaining Libor, Lender shall so notify Borrower and Borrower
then shall have the option of reconverting the method of computing the interest
rate on the Prime Rate Portion into a Libor Portion.
 
     (F) Taxes and Increased Costs. With respect to any Libor Portion, if Lender
shall determine in good faith that any change in any applicable law, treaty,
regulation or guideline (including, without limitation, Regulation D of the
Board of Governors of the Federal Reserve System) or any new law, treaty,
regulation or
 
                                        6
<PAGE>   168
 
guideline, or any interpretation of any of the foregoing by any governmental
authority charged with the administration thereof or any central bank or other
fiscal, monetary or other authority having jurisdiction over Lender or its
lending branch or the Libor Portions contemplated by this Agreement (whether or
not having the force of law) shall:
 
          (i) impose, increase, or deem applicable any reserve, special deposit
     or similar requirement against assets held by, or deposits in or for the
     account of, or loans by, or any other acquisition of funds or disbursements
     by, Lender which is not in any instance already accounted for in computing
     the interest rate applicable to such Libor Portion;
 
          (ii) subject Lender, any Libor Portion or the Revolving Note to the
     extent it evidences such Portion, to any tax (including, without
     limitation, any United Stated interest equalization tax or similar tax
     however named applicable to the acquisition or holding of debt obligations
     and any interest or penalties with respect thereto), duty, charge, stamp
     tax, fee, deduction or withholding in respect of this Agreement, any Libor
     Portion or the Revolving Note to the extent it evidences such Portion,
     except such taxes as may be measured by the overall net income or gross
     receipts of Lender or its lending branches and imposed by the jurisdiction,
     or any political subdivision or taxing authority thereof, in which Lender's
     principal executive office or its lending branch is located;
 
          (iii) change the basis of taxation of payments of principal and
     interest due from Borrower to Lender hereunder or under the Revolving Note
     to the extent it evidences any Libor Portion (other than by a change in
     taxation of the overall net income or gross receipts of Lender); or
 
          (iv) impose on Lender any penalty with respect to the foregoing or any
     other condition regarding this Agreement, its disbursement, any Libor
     Portion or the Revolving Note to the extent it evidences any Libor Portion;
     and Lender shall determine that the result of any of the foregoing is to
     increase the cost (whether by incurring a cost or adding to a cost) to
     Lender of creating or maintaining any Libor Portion hereunder or to reduce
     the amount of principal or interest received or receivable by Lender
     (without benefit of, or credit for, any prorations, exemption, credits or
     other offsets available under any such laws, treaties, regulations,
     guidelines or interpretations thereof), then the interest rate on the
     Revolving Note shall be converted to the Prime Rate Portion. If Lender
     makes such a determination, Lender shall provide to Borrower a certificate
     setting forth the computation of the increased cost or reduced amount as a
     result of any event mentioned herein in reasonable detail and such
     certificate shall be conclusive if reasonably determined.
 
     (G) Funding Indemnity. In the event Lender shall incur any loss of profit,
and any loss, cost or expense (including, without limitation, any loss, cost or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired or contracted to be acquired by Lender to fund or maintain
any Libor Portion, or the relending or reinvesting of such deposits or other
funds or amounts paid or prepaid to Lender) as a result of:
 
          (i) any payment of a Libor Portion on a date other than the last day
     of the then applicable Interest Period for any reason, whether before or
     after the occurrence of any Event of Default, and whether or not such
     payment is required by any provisions of this Agreement; or
 
          (ii) any failure by Borrower to create, borrow, continue or effect by
     conversion a Libor Portion on the date specified in a notice given pursuant
     to this Agreement; then upon the demand of Lender, Borrower shall pay to
     Lender such amount as will reimburse Lender for such loss, cost or expense.
     Without limitation of the foregoing, any prepayment of a Libor Portion on a
     date other than the last day of the then applicable Interest Period shall
     be accompanied by a prepayment penalty equal to the loss Lender shall
     suffer as a result of Libor as calculated on the date of such prepayment
     for the period of time equal to the Interest Period for such Libor Portion
     being prepaid being less than Libor applicable to the Libor Portion being
     prepaid. If Lender requests such a reimbursement Lender shall provide
     Borrower with a certificate setting forth the computation of the loss of
     profit and any loss, cost or expense giving rise to the request for
     reimbursement in reasonable detail and such certificate shall be conclusive
     if reasonably determined.
 
                                        7

     (H) Lending Branch. Lender may, at its option, elect to make, fund or
maintain Portions of the Loans hereunder at such of its branches or offices as
Lender may from time to time elect.
 
     (I) Discretion of Bank as to Manner of Funding. Notwithstanding any
provision of this Agreement to the contrary, Lender shall be entitled to fund
and maintain its funding of all or any part of the Revolving Note in any manner
Lender sees fit; it being understood, however, that for the purposes of this
Agreement all determinations hereunder shall be made as if Lender had actually
funded and maintained each Libor Portion, or its share thereof, during each
Interest Period applicable thereto through the purchase of deposits in the
relevant market in the amount of such Libor Portion, having a maturity
corresponding to such Interest Period and bearing an interest rate equal to the
interest rate applicable to such Libor Portion for such Interest Period.
 
     (J) Prepayments on Libor Portions. Borrower may prepay any Libor Portion of
the Revolving Note only on the last date of the then applicable Interest Period,
in whole or in part (but, if in part, then in an amount not less than
$100,000.00 or such greater amount which is an integral multiple of $100,000.00)
upon three (3) Business Days' prior notice to Lender (which notice shall be
irrevocable once given, must be received by Lender no later than 9:00 a.m.
(Chicago time) on the third Business Day preceding the date of such prepayment
and shall specify the principal amount to be repaid). Any such prepayment shall
be effected by payment of the principal amount to be prepaid and accrued
interest thereon to the end of the applicable Interest Period.
 
     (K) Notations and Requests. All Revolving Loans made against the Revolving
Note, the status of all amounts evidenced by the Revolving Note as constituting
part of the Prime Rate Portion or a Libor Portion and the rates of interest and
Interest Periods applicable to such Portions shall be recorded by Lender on its
books and records or, at its option in any instance, endorsed on schedules to
the Revolving Note and the unpaid principal balance and status, rates and
Interest Periods so recorded or endorsed by Lender shall be prima facie evidence
in any court or other proceeding brought to enforce the Revolving Note of the
principal amount remaining unpaid thereon, the status of the Revolving Loans
evidenced thereby and the interest rates and Interest Periods applicable
thereto; provided, however, that the failure of Lender to record any of the
foregoing shall not limit or otherwise affect the obligation of Borrower to
repay the principal amount of the Revolving Note together with accrued interest
thereon.
 
     SECTION 2.4. Requests for Revolving Loans. Subject to the terms and
provisions of this Agreement, each request by the Borrower for any draw under
the Line of Credit shall be made in accordance with Lender's Automatic Loan
Manager Program.

     SECTION 3.1. Security Interests. To secure payment of the Liabilities,
Borrower hereby irrevocably pledges, assigns, transfers, conveys and sets over
to the Lender and hereby grants to the Lender a first and paramount security
interest in and to the Collateral, howsoever arising, wherever located and

     SECTION 3.2. Perfection and Filing Requirements. Borrower shall perform any
and all acts requested by the Lender to establish, maintain and continue the
Lender's security interests and liens in the Collateral, including but not
limited to, executing financing statements and such other instruments and
documents when and as reasonably requested by the Lender.

     (A) Borrower shall establish a "lock box" account at the Lender (the "Lock
Box"), subject to the control of the Lender, and pursuant to Lender's standard
form lock-box agreement (the "Lock Box Agreement"). Borrower, at its expense,
will notify or cause to be notified all Account Debtors to pay directly any sum
or sums then due or to become due on the Accounts Receivable to the Lock Box.
 
                                        8
<PAGE>   170
 
     (B) Unless otherwise provided herein and subject to the provisions of
Section 3.3(A) of this Agreement, Borrower may collect through the Lock Box at
its own expense the Accounts Receivable in the ordinary course of business;
provided, however, that Borrower's authorization to collect through the Lock Box
the Accounts Receivable is subject to the following:
 
          (i) The Lender, at any time after the occurrence of an Event of
     Default, may, in its sole discretion, notify any or all of the Account
     Debtors that (1) the Accounts Receivable have been assigned to the Lender;
     and/or (2) that all further payments on the Accounts Receivable should be
     paid solely to the Lender. When requested by the Lender after the
     occurrence of an Event of Default, Borrower at its expense will notify or
     cause to be notified any or all Account Debtors to pay directly to the
     Lender any sum or sums then due or to become due on the Accounts Receivable
     or any part thereof and all bills and statements thereafter sent by
     Borrower to such Account Debtors shall state that the same have been
     assigned to the Lender and are payable solely to the Lender;
 
          (ii) In the event an Account Debtor is notified under Subsection
     3.3(B)(i) of this Agreement or one or more Events of Default have occurred
     under the terms of this Agreement, the Lender shall have and succeed to all
     rights, remedies, securities and liens of Borrower in respect to such
     Accounts Receivable or other Collateral, including, but not limited to, the
     right of stoppage in transit of any merchandise, guarantees or other
     contracts or suretyship with respect to any such merchandise, warranties,
     unpaid seller's liens, statutory liens, artisans' liens, or the right to
     other collateral security held by or to which Borrower is entitled for the
     payment of any such merchandise, and shall have the right to enforce the
     same in its name or to direct the enforcement thereof by Borrower for the
     benefit of the Lender, and Borrower shall, at the request of the Lender,
     deliver to the Lender a separate written assignment of any of the same. The
     Lender, however, shall not incur any obligation or liability of Borrower to
     any Account Debtor, including, but not limited to, obligations or
     liabilities pursuant to any con tract, agreement, warranty, guarantee,
     judicial decree or jury award. The Lender, in such an event, is also hereby
     irrevocably authorized to receive, open and dispose of all mail addressed
     to Borrower, to notify the Post Office authorities to change the address
     for delivery of Borrower's mail to an address designated by the Lender, to
     endorse Borrower's name on all notes, checks, drafts, bills of exchange,
     money orders, commercial paper of any kind whatsoever, and any other
     instruments or documents received howsoever in payment of the Accounts
     Receivable, or any part thereof, and the Lender or any officer or employee
     thereof is hereby irrevocably constituted and appointed agent and
     attorney-in-fact for Borrower for the foregoing purpose;
 
          (iii) Borrower shall not collect, compromise or accept any sum in full
     payment or satisfaction of any of the Accounts Receivable for materially
     less than the amount due without the express written consent of the Lender,
     except in the ordinary course of business; and
 
          (iv) The Lender may directly request the Account Debtors for written
     confirmations of the Accounts Receivable at any time whether before or
     after the occurrence of an Event of Default.
 
     (C) All collections of Accounts Receivable through the Lock Box shall be
deposited into a cash collateral account located at and controlled by Lender and
for bookkeeping purposes be credited against the Line of Credit (1) banking day
after the date of deposit into such cash collateral account with Lender;
provided, however, that (i) all such credits shall be and are conditional
credits which shall only become final upon collection in immediately available
funds; and (ii) any funds that are electronically transferred from another
financial institution to such cash collateral account shall for bookkeeping
purposes be credited against the Line of Credit one (1) banking day after the
date of deposit into such cash collateral account.
 
     SECTION 3.4. Use of Collateral. Borrower shall at all times keep the
Collateral in good condition and repair and free and clear of all unpaid charges
(including, but not limited to, taxes), liens and encumbrances, and shall pay or
cause to be paid all obligations as they come due, including but not limited to,
mortgage payments, real estate taxes, assessments and rent due on the premises
where the Collateral is or may be located, except for charges, liens,
encumbrances and obligations being contested in good faith by Borrower and for
which adequate reserves have been established. Borrower agrees that (except as
provided in the immediately preceding sentence) in the event Borrower fails to
pay such obligations, the Lender may, at its
 
                                        9
<PAGE>   171
 
sole and arbitrary discretion, pay such obligations for the account of Borrower.
The Lender may, in its sole discretion, discharge taxes, liens or security
interests or other encumbrances at any time levied or placed on the Collateral
and may, in its sole and arbitrary discretion, pay for the maintenance and
preservation of the Collateral. Any payments made by the Lender pursuant to this
Section shall be repayable to the Lender by Borrower immediately upon the
Lender's demand therefor, with interest at a rate equal to the highest interest
rate described in the Note in effect from time to time during the period from
and including the date funds are so expended by the Lender to the date of
repayment, and any such amounts due and owing the Lender shall be an additional
obligation of Borrower to the Lender secured hereunder.
 
     SECTION 3.5. Software Agreements. As additional security for the payment of
the Liabilities, Borrower shall execute and deliver an assignment of all of the
Software Agreements (the "Software Assignment"), in form and manner satisfactory
to Lender.
 
     SECTION 3.6. Patents, Trademarks and Licenses. As additional security for
the payment of the Liabilities, the Borrower shall execute and deliver to Lender
a patent, trademark and license security agreement (the "Patent and Trademark
Agreement") pursuant to which all of the patents, trademarks and licenses of the
Borrower are pledged to Lender, in form and manner satisfactory to Lender.
 
     SECTION 3.7. Copyrights and Licenses. As additional security for the
payment of the Liabilities, the Borrower shall execute and deliver to Lender a
copyright and license security agreement (the "Copyright Agreement") pursuant to
which all of the copyrights and licenses of the Borrower are pledged to Lender,
in form and manner satisfactory to Lender.
 
     SECTION 3.8. Cross Collateralization. The Borrower acknowledges and agrees
that (A) the Collateral secures all of the Loans and (B) Lender shall not
release any lien on the Collateral unless and until all the Liabilities are paid
in full.

     and in its sole and arbitrary discretion, sell the Collateral at public or

     the net proceeds, after deducting all costs, expenses and attorneys' fees
     incurred at any time in the collection of the indebtedness of Borrower to
     the Lender and in the protection and sale of the Collateral, to the payment
     of said indebtedness, returning the remaining proceeds, if any, to

this Article Eight or under applicable law shall be reasonably and properly
given to Borrower at the address and by any of the methods of giving such notice
as set forth in Section 9.3 of this Agreement, at least 10 days before taking

                                 MISCELLANEOUS
 
     SECTION 9.1. No Waiver; Modifications in Writing. No failure or delay on
the part of Lender in exercising any right, power or remedy pursuant to the

exercise thereof, or the exercise of any other right, power or remedy. No
amendment, modification, supplement, termination or waiver of any provision of
the Documents, nor any consent by Lender to any departure by Borrower therefrom,
shall be effective unless the same shall be in writing and signed by Lender. Any
waiver of any provision of the Documents and any consent by Lender to any
departure by Borrower from the terms of any provision of the Documents shall be
effective only in the specific instance and for the specific purpose for which

interest in all such property.

     SECTION 9.4. Costs, Expenses and Taxes. Borrower agrees to pay all
out-of-pocket fees and expenses of Lender (including, but not limited to, UCC
Filing and Search Fees and fees and reasonable expenses of outside counsel to
Lender and paralegals) in connection with the making of the Loans and
preparation, administration and enforcement of the Documents and the Loans;
provided, however, that solely with respect to the fees and costs of Lender's
counsel in connection with the preparation and negotiation of the Documents and
making of the Loans on the Closing Date, Borrower shall only be responsible for
all of Lender's counsel's out-of-pocket expenses plus up to $5,000.00 of
Lender's legal fees incurred in connection with the preparation and negotiation
of the Documents and making of the Loans through the Closing Date. In addition,
Borrower

<PAGE>   180
 
shall pay any and all stamp, transfer and other taxes payable or determined to
be payable in connection with the execution and delivery of the Documents and
agrees to hold the Lender harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes.
If any suit or proceeding arising from any of the foregoing is brought against
Lender, Borrower, to the extent and in the manner directed by Lender, will
resist and defend such suit or proceeding or cause the same to be resisted and
defended by counsel approved by Lender. If Borrower shall fail to do any act or
thing which it has covenanted to do under this Agreement or any representation
or warranty on the part of Borrower contained in this Agreement shall be
breached, Lender may, in its sole and arbitrary discretion, after 10 days
written notice is sent to Borrower, do the same or cause it to be done or remedy
any such breach, and may expend its funds for such purpose; and any and all
amounts so expended by the Lender shall be repayable to the Lender by Borrower
immediately upon the Lender's demand therefor, with interest at a rate equal to
the highest interest rate set forth in the Note in effect from time to time
during the period from and including the date funds are so expended by Lender to
the date of repayment, and any such amounts due and owing Lender shall be deemed
to be part of the Liabilities secured hereunder. The obligations of Borrower
under this Section shall survive the termination of this Agreement and the
discharge of the other obligations of Borrower under the Documents.
 
     SECTION 9.5. Computations. Where the character or amount of any asset or
liability or item of income or expense is required to be determined, or any
consolidation or other accounting computation is required to be made, for the
purpose of this Agreement, such determination or calculation shall, to the
extent applicable and except as otherwise specified in this Agreement, be made
in accordance with generally accepted accounting principles applied on a basis
consistent with those at the time in effect.
 
     SECTION 9.6. Further Assurances. Borrower agrees to do such further acts
and things and to execute and deliver to Lender such additional assignments,
agreements, powers, documents and instruments as Lender may reasonably require
or deem advisable to carry into effect the purposes of the Documents, or to
confirm unto Lender its rights, powers and remedies under the Documents.
 
     SECTION 9.7. Counterparts. This Agreement may be executed in any number of
counterparts, each of which counterparts, once they are executed and delivered,
shall be deemed to be an original and all of which counterparts, taken together,
shall constitute but one and the same agreement.
 
     SECTION 9.8. Binding Effect; Assignment. This Agreement shall be binding
upon, and inure to the benefit of, Lender, Borrower and their respective
successors, assigns, representatives and heirs. Borrower shall not assign any of
its rights nor delegate any of its obligations under the Documents without the
prior written consent of Lender and no such consent by Lender shall, in any
event, relieve Borrower of any of its obligations under the Documents.
 
     SECTION 9.9. Headings. Captions contained in this Agreement are inserted
only as a matter of convenience and in no way define, limit or extend the scope
or intent of this Agreement or any provision of this Agreement and shall not
affect the construction of this Agreement.
 
     SECTION 9.10. Entire Agreement. This Agreement, together with the
Documents, contains the entire agreement between the parties hereto with respect
to the transactions contemplated herein and supersede all prior representations,
agreements, covenants and understandings, whether oral or written, related to
the subject matter of the Agreement. Except as specifically set forth in this
Agreement, Lender makes no covenants to Borrower, including, but not limited to,
any other commitments to provide any additional financing to Borrower.
 
     SECTION 9.11. Governing Law. This Agreement shall be deemed to be a
contract made under the laws of the State of Illinois and for all purposes shall
be construed in accordance with the laws of the State of Illinois.
 
     SECTION 9.12. Severability of Provisions. Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective only to the extent of such prohibition or
unenforceability without invalidating the remaining provisions of this Agreement
or affecting the validity or enforceability of such provision in any other
jurisdiction.

     SECTION 9.13. Conflict. In the event of any conflict between this Agreement
and any of the other Documents, the terms and provisions of this Agreement shall
govern and control.
 
     SECTION 9.14. Jurisdiction; Waiver. BORROWER ACKNOWLEDGES THAT THIS
AGREEMENT IS BEING SIGNED BY THE LENDER IN PARTIAL CONSIDERATION OF LENDER'S
RIGHT TO ENFORCE IN THE JURISDICTION STATED BELOW THE TERMS AND PROVISION OF
THIS AGREEMENT AND THE DOCUMENTS. BORROWER CONSENTS TO JURISDICTION IN THE STATE
OF ILLINOIS AND VENUE IN ANY FEDERAL OR STATE COURT IN THE COUNTY OF COOK FOR
SUCH PURPOSES AND THEY WAIVE ANY AND ALL RIGHTS TO CONTEST SAID JURISDICTION AND
VENUE. BORROWER WAIVES ANY RIGHTS TO COMMENCE ANY ACTION AGAINST LENDER IN ANY
JURISDICTION EXCEPT THE AFORESAID COUNTY AND STATE. LENDER AND BORROWER HEREBY
EACH EXPRESSLY WAIVE ANY AND ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY
WITH RESPECT TO ANY MATTER WHATSOEVER RELATING TO, ARISING OUT OF OR IN ANY WAY
CONNECTED WITH THE LOANS, THE DOCUMENTS AND/OR THE TRANSACTIONS WHICH ARE THE
SUBJECT OF THE DOCUMENTS.
 
     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered at Chicago, Illinois as of the date first above
written.

                          MEDICUS SYSTEMS CORPORATION
 
                         NOTES TO FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE 1. BASIS OF PRESENTATION
 
     In management's opinion, the financial statements of Medicus Systems
Corporation (the "Company" or "Medicus") reflect all adjustments (consisting
only of normal recurring adjustments) considered necessary for a fair
presentation of the operating results for the quarters and six months ended
November 30, 1997 and 1996. Certain reclassifications have been made in the
prior period financial statements to conform to the current period presentation.
These reclassifications had no effect on previously reported total assets, total
liabilities, equity or results of operations.
 
     Operating results for the interim periods are not necessarily indicative of
the results to be expected for the full year. The financial information included
herein should be read in conjunction with the financial statements and footnotes
thereto included in the Company's Annual Report on Form 10-K for the year ended
May 31, 1997.
 
     During the quarter and six months ended November 30, 1996, Medicus
performed certain administrative services for Managed Care Solutions, Inc.
("MCS") under a services agreement resulting from the spin off of the Company
from MCS on March 1, 1996. During the quarter and six months ended November 30,
1996, the Company received $175,000 and $350,000, respectively, in consideration
for these services, and reduced marketing, general and administrative expenses
by this amount.
 
NOTE 2. QUADRAMED ACQUISITION
 
     On November 9, 1997, QuadraMed Corporation, a Delaware corporation
("QuadraMed") acquired (the "Acquisition") 56.7% of the outstanding capital
stock of the Company. The Acquisition was completed by means of Stock Purchase
Agreements, dated as of November 9, 1997, with certain stockholders of the
Company (the "Selling Stockholders"). Pursuant to the terms of the Stock
Purchase Agreements, the Selling Stockholders agreed to sell an aggregate of
3,111,105 shares of Medicus Common Stock to QuadraMed. In consideration for the
transfer of these shares to QuadraMed, QuadraMed paid to the Selling
Stockholders $7.50 per share, in cash, without interest, or approximately $23.3
million, together with warrants (the "Warrants") entitling the Selling
Stockholders to acquire 0.3125 shares of QuadraMed Common Stock for each share
of the Medicus Common Stock sold (subject to adjustment in accordance with the
Agreement). The Warrants entitle the Selling Stockholders to purchase QuadraMed
Common Stock at a price of $24.00 per share, on the terms set forth in the
Warrants.
 
     Simultaneously with the execution of the Stock Purchase Agreements,
QuadraMed and the Company entered into an Agreement and Plan of Reorganization
dated as of November 9, 1997 (the "Agreement") pursuant to which a wholly-owned
subsidiary of QuadraMed will be merged, subject to the approval of the
stockholders of QuadraMed, with and into the Company (the "Merger"). At the
effective time of the Merger, the stockholders of the Company participating in
the Merger will exchange all outstanding shares of Medicus Common Stock for any
of (i) a cash payment of $7.50 per share of Medicus Common Stock, (ii) 0.3125
shares of QuadraMed Common Stock per share of Medicus Common Stock sold (subject
to adjustment in accordance with the Agreement), or (iii) a combination of
QuadraMed Common Stock and cash. In addition, all stock options previously
issued by Medicus and outstanding at the time of the Merger will be assumed by
QuadraMed at an exchange ratio of 0.3565 shares of QuadraMed Common Stock for
each share of Medicus Common Stock subject to such options. The Acquisition is
intended to qualify as a tax-free reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986 and will be accounted for as a
purchase transaction.
 
     The acquisition is subject to approval of the Company's stockholders at a
Special Meeting of Stockholders. The terms of the acquisition are set forth in
the Agreement filed with the Securities and Exchange Commission by QuadraMed on

NOTE 3. RESTRUCTURING CHARGES
 
     During February, 1996, the Company commenced a process to evaluate its
current strategic position, including the markets it expects to pursue and its
product offerings in those chosen markets. As a result of decisions made as part
of this evaluation process, the Company recorded $4.7 million in restructuring
charges, representing costs and expenses to exit certain product lines, to
abandon certain product development efforts and to provide for liabilities
resulting from the strategic redirection of the Company, including severance
costs. Specifically, the Company decided to exit the Clinical Case Management
Systems ("CCM") and the Executive Information Systems product lines.
Additionally, product development efforts for the Clinical Data Systems Wincoder
V2 project and portions of the MACH 1 project, which will no longer be utilized
in the Medicus product line, were abandoned and their associated development
costs, which had been previously capitalized, were expensed. Severance costs
associated with an officer and several employees, in addition to the write-off
of a portion of the Contract Management System, were also included in the
restructuring charge.
 
     As part of an ongoing evaluation, the Company refined its strategic
planning process during fiscal 1997, and assessed continuing obligations
associated with the implementation of the plan. The Company continued the
process of implementing its plans during 1997 and, following the stock
repurchase from its founder in the quarter ended February 28, 1997, recorded
$2.8 million in charges to complete its plan, including accruing certain costs
to reorganize the Company's business units, to abandon certain development
efforts, and to increase the allowance for doubtful accounts. Specifically, the
Company decided to relocate operations for its Clinical Data Systems ("CDS")
division, based in Alameda, CA, to the Company's Evanston, IL corporate offices.
Costs accrued associated with the relocation included costs to cancel existing
lease agreements, to terminate employees and to write down abandoned assets. In
addition, the Company increased its reserves for product line exit costs and
severance costs that relate to the remaining customer of the previously
discontinued CCM product line. Also, certain product development efforts for the
Company's Patient Focused Systems ("PFS") products were abandoned, and the
associated development costs, which had been previously capitalized, along with
other related product line exit costs were expensed. The Company also increased
its allowance for doubtful accounts due to the potential for certain additional
billed and unbilled accounts to become uncollectible as a result of the
decisions discussed above.
 
     The components of the restructuring reserve, which the Company expects will
be utilized during the next six months, are as follows:

months ended November 30, 1997, the Company incurred $79,647 in write-downs of
accounts receivable and $22,800 in product line exit costs related to the
remaining customer of the previously discontinued CCM product line. The Company
also paid $256,047 in business unit reorganization costs related to the
relocation of the CDS division and $261,306 in severance benefits and employee
termination costs.

NOTE 4. DISCONTINUED OPERATION
 
     Effective May 31, 1997 the Company adopted a plan to discontinue its
contract services line of business. This separate line of business consisted of
information systems management contracts with Bethesda, Inc. As a result of this
decision, the net assets of the contract services line of business, principally
accounts receivable and unbilled services, property and equipment, and accounts
payable and other accrued liabilities have been reclassified in the Balance
Sheets at November 30, 1997 and May 31, 1997. In addition, the results of
operations of the contract services business have been reclassified in the
Statements of Operations for the quarters and six months ended November 30, 1997
and 1996 and in the Statements of Cash Flows for the six months ended November
30, 1997 and 1996.
 
     The following table summarizes unaudited selected financial data of the
contract services business for the quarters and six months ended November 30,
1997 and 1996:

</TABLE>
 
     In December 1997, following meetings with representatives from both Medicus
and Bethesda, Inc., the contracts to manage the information systems functions
were terminated, effective December 31, 1997. As a result, the Company recorded
$150,000 in related settlement costs for the quarter and six months ended
November 30, 1997.
 
NOTE 5. EARNINGS PER SHARE
 
     Earnings (loss) per common share have been computed by dividing net income
(loss) by the weighted average of common stock and common stock equivalents
outstanding during the period. Common stock equivalents include shares issuable
on the exercise of stock options and the warrant (when dilutive), using the
treasury method from the date of grant. Common stock equivalents are not
included in the calculation of loss per share because they are antidilutive.
 
NOTE 6. NOTE PAYABLE AND LINE OF CREDIT
 
     On December 5, 1996, the Company reached an agreement in principle with its
founder, Richard C. Jelinek, to purchase from Mr. Jelinek, and a trust of which
he is a beneficiary (the "Trust"), one million shares of Medicus Common Stock
and 500 shares of Medicus Voting Preferred Stock. In exchange, the Company
agreed to pay Mr. Jelinek and the Trust $4.5 million in cash and $2.0 million in
8% two-year promissory notes, and issued to Mr. Jelinek and the Trust 400,000
five-year warrants to purchase Medicus Common Stock at $8.00 per share. Interest
costs incurred and paid on the promissory notes totaled $40,040 and $79,705 for
the quarter and six months ended November 30, 1997. In December 1997, the notes
and related interest were redeemed in their entirety by QuadraMed.
 
     In April 1997, the Company entered into an agreement with a bank that
provides for a secured, revolving line of credit up to a maximum of $2.5
million. The credit facility, which has an initial maturity date of October
1998, bears interest at the bank's prime rate and provides the bank with a first
security interest in all assets of the Company. Certain financial covenants and
reporting requirements are also included in the agreement. As of November 30,
1997, the Company had not utilized the line of credit.

                             RESULTS OF OPERATIONS
 
     This report contains statements that may be considered forward-looking,
such as the discussion of the Company's strategic goals, new products and cash
flows. These statements speak of the Company's plans, goals or expectations,
refer to estimates, or use similar terms. Actual results could differ materially
from the results indicated by these statements because the realization of those
results is subject to many uncertainties.
 
     Some of these uncertainties that may affect future results are discussed in
more detail below under "Management's Discussion and Analysis of Financial
Condition and Results of Operations." All forward-looking statements included in
this document are based upon information presently available, and the Company
assumes no obligation to update any forward-looking statement.
 
     The Company's quarterly operating results historically have varied
depending upon such factors as the timing of significant sales and the timing of
new product introductions. Consequently, the results for any one quarter may not
be indicative of future operating results.
 
     The following table sets forth for the periods indicated (i) the percent of
revenues represented by certain line items in the Company's Statements of
Operations and (ii) the percentage change in each line item from the prior year
period.

                          MEDICUS SYSTEMS CORPORATION
 
                       RESULTS OF OPERATIONS (CONTINUED)
 
SOFTWARE PRODUCTS AND SERVICES
 
     Revenues decreased 39% to $1.4 million for the quarter and 12% to $3.6
million for the six months, primarily due to sales force turnover and continued
weakness in the Company's primary markets and product lines. Also contributing
to the decline for the six months were delays in the release of certain Windows
based products from the Clinical Data Systems and Decision Support Systems
divisions. Costs and expenses decreased 27% for the quarter but increased 1% for
the six months, compared to the corresponding prior year period, and as a
percentage of related revenues, increased to 38% from 32% for the quarter and to
34% from 30% for the six months. The decrease for the quarter and six months
resulted primarily from lower personnel and service-related expenses, partially
offset by increased amortization of capitalized software for the newly released
products. In addition, costs and expenses for the six months ended November 30,
1996 included the effect of the Company's decision to reduce its reserve for
continuing obligations on product line exit costs by $200,000, as a result of
favorable negotiations with its customers.
 
MAINTENANCE AND SUPPORT SERVICES
 
     Revenues decreased 17% to $2.4 million for the quarter and 9% to $4.8
million for the six months, primarily due to modest increases associated with
customer migrations being more than offset by discontinued support services on
individual modules from the Company's PFS customers as well as slightly higher
cancellations overall. Costs and expenses for the quarter decreased 1% but
increased 11% for the six months compared to the corresponding prior year
periods, and as a percentage of related revenues, increased to 58% from 49% for
the quarter and to 53% from 43% for the six months. The increase for the six
months is primarily due to additional labor costs incurred to support new
product releases from the Clinical Data Systems and Decision Support Systems
divisions and higher labor costs resulting from shifts to maintenance and
support activities from development activities.
 
MARKETING, GENERAL AND ADMINISTRATIVE
 
     Expenses increased 19% to $2.7 million for the quarter and 26% to $5.4
million for the six months. The increase was primarily due to $162,000 and
$301,000 in costs and expenses, for the quarter and six months, respectively,
related to the move of the Alameda office. Additionally, costs and expenses for
the quarter and six months ended November 30, 1996 include the effect of
$175,000 and $350,000, respectively, in administrative fees the Company received
as a result of the services agreement with MCS. Costs and expenses for the
quarter ended November 30, 1996 also include the effect of the Company's
decision to reduce its reserve for future severance obligations by $100,000, due
to favorable settlements with two of its employees.
 
RESEARCH AND DEVELOPMENT
 
     Actual research and development expenses decreased 52% to $576,000 for the
quarter and 29% to $1,627,000 for the six months. Research and development costs
presented in the accompanying financial statements were $522,000 and $1,503,000
for the quarter and six months, respectively, compared to $699,000 and
$1,204,000 in the corresponding prior year periods. The Company also capitalized
software development costs of $54,000 and $124,000 during the quarter and six
months, respectively, compared to $476,000 and $947,000 in the corresponding
prior year periods, reflecting the release of new products in the quarter ended
August 31, 1997 and the resulting cessation of software cost capitalization.
Actual research and development expenditures were 42% and 45% of software
products and services revenues for the quarter and six months ended November 30,
1997, respectively, compared to 52% and 56% in the corresponding prior year
periods.
 
     During the first six months of fiscal 1998, the Company's development
efforts were focused on the Decision Support Systems product line and the
Clinical Data Systems product line. During the first six months of fiscal 1997,
the Company was engaged in several development projects, including the Resource
Case Management System, and the Decision Support Systems and Clinical Data
Systems product lines.

INTEREST AND OTHER INCOME, NET
 
     Interest and other income, net decreased 96% to $6,000 for the quarter and
97% to $9,000 for the six months, primarily due to lower average cash balances
and interest expense incurred relating to the promissory notes.
 
INCOME TAXES
 
     The Company's effective tax rate was 38.5% for the quarter and six months
ended November 30, 1997, compared to 37.3% and 38.8% in the corresponding prior
periods.
 
                              FINANCIAL CONDITION
 
     As a result of the Company's commitment to expand its software products and
services, funds are required to support its ongoing product research and
development activities and the infrastructure required to serve its customer
base. Historically, cash generated from its operations has been an important
contributor to these needs. As a result of the market factors adversely
affecting fiscal 1997 results, as well as the stock repurchase transaction, the
Company was required to use a significant portion of its cash reserves. It is
expected that, following the restructuring efforts begun in prior periods, the
Company will return to a situation where cash from operations will provide an
important source of liquidity to support its normal capital needs, although
numerous factors, including any reductions in revenues from currently
anticipated amounts, could affect the amount of such cash available.
 
     At November 30, 1997, the Company had available cash reserves of $244,000.
In addition, the Company had a $2.5 million standby credit facility as well as
funds from QuadraMed available. The Company anticipates cash outlays of
approximately $1.7 million in the next six months, resulting primarily from its
decision to reorganize its business units and to exit certain product lines.
However, cash outlays related to the Company's 8% promissory notes no longer
exist since the notes were redeemed in their entirety by QuadraMed in December,
1997.
 
     While the Company has experienced negative cash flows from operating
activities during the past two fiscal years, management believes that, as a
result of significant reductions in expenses, its cash flows will improve. While
there can be no assurance that this will occur, the Company currently believes
that it will have adequate financial resources available from operations and the
available credit facility and intercompany (QuadraMed) sources to provide
sufficient liquidity to meet its ordinary capital requirements for the
foreseeable future, including cash outlays related to the Company's
restructuring plan.
 
     During its second fiscal quarter, the Company billed its clients in advance
for the next calendar year's maintenance and support services provided on its
software products. This generated an increase in the Company's accounts
receivable and deferred revenue balances, and will increase cash balances in
subsequent months as the related accounts receivable are collected.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
     Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share," issued in February 1997, changes the method of calculating earnings per
share and will be effective for the Company's financial statements for the year
ending May 31, 1998. Earlier application is not permitted. However, the Company
is permitted to disclose pro forma earnings per share amounts computed using
SFAS 128 in periods prior to adoption. Upon adoption, all prior period earnings
per share data presented shall be restated to conform to SFAS 128. The
calculation of earnings per share under SFAS 128 is simpler than prior methods
and more consistent with international accounting standards. Because a majority
of the Company's common stock equivalents have exercise prices in excess of the
Company's Common Stock price, the Company does not believe that the adoption of
SFAS 128 will have a significant impact on amounts reported as net income (loss)
per common share.

ITEM 5.  OTHER INFORMATION.
 
     On November 9, 1997, QuadraMed Corporation, a Delaware corporation
("QuadraMed") acquired (the "Acquisition") 56.7% of the outstanding capital
stock of the Company. The Acquisition was completed by means of Stock Purchase
Agreements, dated as of November 9, 1997, with certain stockholders of the
Company (the "Selling Stockholders"). Pursuant to the terms of the Stock
Purchase Agreements, the Selling Stockholders agreed to sell an aggregate of
3,111,105 shares of Medicus Common Stock to QuadraMed. In consideration for the
transfer of these shares to QuadraMed, QuadraMed paid to the Selling
Stockholders $7.50 per share, in cash, without interest, or approximately $23.3
million, together with warrants (the "Warrants") entitling the Selling
Stockholders to acquire 0.3125 shares of QuadraMed Common Stock for each share
of the Medicus Common Stock sold (subject to adjustment in accordance with the
Agreement). The Warrants entitle the Selling Stockholders to purchase QuadraMed
Common Stock at a price of $24.00 per share, on the terms set forth in the
Warrants.
 
     Simultaneously with the execution of the Stock Purchase Agreements,
QuadraMed and the Company entered into an Agreement and Plan of Reorganization
dated as of November 9, 1997 (the "Agreement") pursuant to which a wholly-owned
subsidiary of QuadraMed will be merged, subject to the approval of the
stockholders of QuadraMed, with and into the Company (the "Merger"). At the
effective time of the Merger, the stockholders of the Company participating in
the Merger will exchange all outstanding shares of Medicus Common Stock for any
of (i) a cash payment of $7.50 per share of Medicus Common Stock, (ii) 0.3125
shares of QuadraMed Common Stock per share of Medicus Common Stock sold (subject
to adjustment in accordance with the Agreement), or (iii) a combination of
QuadraMed Common Stock and cash. In addition, all stock options previously
issued by Medicus and outstanding at the time of the Merger will be assumed by
QuadraMed at an exchange ratio of 0.3565 shares of QuadraMed Common Stock for
each share of Medicus Common Stock subject to such options. The Acquisition is
intended to qualify as a tax-free reorganization within the meaning of Section
368 (a) of the Internal Revenue Code of 1986 and will be accounted for as a
purchase transaction.

Ladies and Gentlemen:

         The undersigned agrees to deliver the stock certificates (the
"Certificates") identified in Column 1 of Box A below representing the total
number of shares of Common Stock of Medicus Systems Corporation ("Medicus"),
par value $.01 per share (the "Medicus Common Stock"), set forth in Column 2 of
Box A.  Delivery of the Certificates will be made in accordance with
instructions provided by the Exchange Agent promptly after the effective time
of the Merger, as described below.

         The Medicus Common Stock is being purchased pursuant to the terms of
an Agreement and Plan of Reorganization, dated as of November 9, 1997 (the
"Merger Agreement"), by and among QuadraMed Corporation and Medicus, pursuant
to which a wholly owned subsidiary of QuadraMed will be merged with and into
Medicus
<PAGE>   2
(the "Merger"), and each share of Medicus Common Stock issued and outstanding
at the effective time of the Merger will be converted into the right to receive
any of (i) a cash payment of $7.50 per share of Medicus Common Stock (a "Cash
Election"), (ii) 0.3125 shares of Common Stock, par value $.01 per share, of
QuadraMed (the "QuadraMed Common Stock") for each share of Medicus Common Stock
(a "Stock Election"), subject to adjustment and certain limitations as provided
in the Merger Agreement, or (iii) a combination of cash and QuadraMed Common
Stock.

         Column 3 of Box A indicates the total number of shares of Medicus
Common Stock to be surrended by the undersigned.  The total number of Medicus
Common Stock listed in Column 4 of Box A represent the undersigned's Cash
Election and shall be converted into cash upon consummation of the Merger at
the rate of $7.50 per share of Medicus Common Stock.  The total number of
Medicus Common Stock listed in Column 5 of Box A represent the undersigned's
Stock Election and shall be converted into .3125 shares of QuadraMed Common
Stock, subject to adjustment and certain limitations as provided in the
following paragraph (the "Exchange Ratio").

         The Exchange Ratio is subject to the following adjustments:  (1) if
the QuadraMed Stock Value exceeds $27.60, then the Exchange Ratio shall be the
quotient obtained by dividing (A) $8.625 by (B) the QuadraMed Stock Value, and
(2) if the QuadraMed Stock Value is less than $24.00, then the Exchange Ratio
shall be the quotient obtained by dividing (A) $7.50 by (B) the QuadraMed Stock
Value.  Additionally, if the QuadraMed Stock Value is less than $20.40, then
QuadraMed may elect, at its sole discretion, to cause all or any portion of the
shares of Medicus Common Stock to be converted into the Per Share Cash Amount
(the "QuadraMed Cash Election").  The "QuadraMed Stock Value" is equal to the
average of the closing prices of QuadraMed Common Stock during the fifteen (15)
days prior to the second day prior to the date of the Special Meeting.  If the
QuadraMed Stock Value (as defined below) is less than $20.40, then QuadraMed
may, at its sole discretion, elect to have all or any portion of the shares of
Medicus Common Stock converted into cash.  QuadraMed will issue no more than
1,800,000 shares of QuadraMed Common Stock pursuant to the Merger and pursuant
to the exercise of warrants held by certain former stockholders of Medicus,
which shares are subject to pro rata allocation in the event stock elections by
Medicus stockholders and warrant exercises exceed the share limitation.

         Consummation of the Merger is subject to various conditions, including
the affirmative vote of holders of a majority of the outstanding shares of
Medicus Common Stock entitled to vote at the Special Meeting.

         NONE OF QUADRAMED, MEDICUS, THE MEDICUS BOARD OF DIRECTORS OR THE
QUADRAMED BOARD OF DIRECTORS OR TRUSTEES MAKES ANY RECOMMENDATION AS TO WHETHER
STOCKHOLDERS OF MEDICUS SHOULD ELECT TO RECEIVE CASH OR SHARES.  EACH MEDICUS
STOCKHOLDER MUST MAKE HIS OR HER OWN DECISION WITH RESPECT TO SUCH ELECTION.

         All questions as to the validity, form and eligibility of any election
made hereunder shall be determined by QuadraMed (or the Exchange Agent agent if
QuadraMed so delegates), and such determination shall be conclusive and
binding.  Neither QuadraMed nor the Exhange Agent shall have any obligation to
to notify any person of a defect in a Form of Election submitted to the
Exchange Agent.  The Exchange Agent shall also make all computations
contemplated by the Merger Agreement and all such computations shall be
conclusive and binding on the holders of Medicus Common Stock.  A holder of
Medicus Common Stock who does not submit a Form of Election which is received
by the Exchange Agent prior to the Election Deadline shall be deemed to have
made a Non-Election.  If QuadraMed or the Exchange Agent shall determine that
any purported Cash Election or Stock Election was not properly made, such
purported Cash Election or Stock Election shall be deemed to be of no force and
effect and the stockholder making such purported Cash Election or Stock
Election shall be deemed to have made a "Non-Election".

         THE UNDERSIGNED UNDERSTANDS AND AGREES THAT THE ACCEPTANCE AND
DELIVERY OF ANY FORMS OF ELECTION BY OR TO THE EXCHANGE AGENT (OR ANY OTHER
AUTHORIZED PERSON) WILL NOT OF ITSELF CREATE ANY RIGHT TO RECEIVE CASH OR
QUADRAMED SHARES

IS PROPERLY REVISED OR WITHDRAWN IN ACCORDANCE WITH INSTRUCTION 4 OR 5 OF THIS
