Dear Stockholder:
 
    A Special Meeting of Stockholders of Access Health, Inc. ("Access Health")
will be held on June 30, 1998 at 9:00 a.m., local time, at Access Health's
offices located at 335 Interlocken Parkway, Broomfield, CO 80021.
 
   
    At this Special Meeting, you will be asked to consider and vote upon the
approval of the issuance of shares of Access Health Common Stock pursuant to the
terms of an Amended and Restated Agreement and Plan of Reorganization dated as
of June 4, 1998 (the "Merger Agreement"), entered into by and among Access
Health, Access Acquisition Corp. 98A, a newly-formed, wholly-owned subsidiary of
Access Health ("Merger Sub"), and InterQual, Inc., a Delaware corporation
("InterQual"), which provides for the merger of Merger Sub with and into
InterQual, with InterQual being the surviving corporation and becoming a
wholly-owned subsidiary of Access Health (the "Merger"), as described in the
Notice of Special Meeting of Stockholders mailed to the stockholders of Access
Health on or about June 12, 1998 and the accompanying Proxy Statement/Prospectus
and Notice and Consent Solicitation Statement.
    
 
    As a result of the Merger, all outstanding shares of InterQual Class A and
Class B Common Stock will be converted into shares of Access Health Common
Stock. Under the terms of the Merger, 4,290,000 shares of Access Health Common
Stock will be exchanged for the outstanding shares of InterQual Class A and
Class B Common Stock. The number of shares exchanged (the "Merger
Consideration") is subject to an increase in the event that the value of the
number of shares of Access Health Common Stock to be exchanged in the Merger is
less than $130 million, computed using the average price per share (the "Market
Price") of Access Health Common Stock over the 20 consecutive trading days
ending three days prior to the closing date of the Merger. In the event such
increase is necessary, the number of shares exchanged will be increased by the
number of shares equal to the lesser of (A) fifty percent (50%) of the amount
obtained from: (1) the quotient of $130 million and the Market Price of Access
Health Common Stock, less (2) 4,290,000, and (B) 250,000. The rules of the
Nasdaq National Market require that the issuance of Access Health Common Stock
pursuant to the Merger Agreement be approved by a majority of the votes cast at
the Special Meeting. Consummation of the proposed Merger is conditioned upon,
among other things, the receipt of all required stockholder approvals.
 
    ACCESS HEALTH'S BOARD OF DIRECTORS HAS UNANIMOUSLY RATIFIED AND APPROVED THE
MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY AND HAS DETERMINED
THAT THE MERGER IS FAIR AND IN THE BEST INTERESTS OF ACCESS HEALTH AND ITS
STOCKHOLDERS. AFTER CAREFUL CONSIDERATION, THE BOARD OF DIRECTORS UNANIMOUSLY
RECOMMENDS A VOTE IN FAVOR OF APPROVAL OF THE ISSUANCE OF SHARES OF ACCESS
HEALTH COMMON STOCK PURSUANT TO THE TERMS OF THE MERGER AGREEMENT.
 
    In the material accompanying this letter, you will find a Notice of Special
Meeting of Stockholders, a Proxy Statement/Prospectus and Notice and Consent
Solicitation Statement relating to the actions to be taken by Access Health
stockholders at the Special Meeting (as well as the actions to be taken by the
InterQual stockholders by written consent) and a Proxy Card. The Proxy
Statement/Prospectus and Notice and Consent Solicitation Statement more fully
describes the proposed Merger and includes information about Access Health and
InterQual.

TO THE STOCKHOLDERS OF ACCESS HEALTH:
 
    NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders of Access
Health, Inc., a Delaware corporation ("Access Health"), will be held on June 30,

    being the surviving corporation and becoming a wholly-owned subsidiary of
    Access Health (the "Merger"). As a result of the Merger, all outstanding
    shares of InterQual Class A and Class B Common Stock will be converted into
    shares of Access Health Common Stock. Under the terms of the Merger,
    4,290,000 shares of Access Health Common Stock will be exchanged for the
    outstanding shares of InterQual Class A and Class B Common Stock. The number
    of shares exchanged (the "Merger Consideration") is subject to an increase

    Stock to be exchanged in the Merger is less than $130 million, computed
    using the average price per share (the "Market Price") of Access Health
    Common Stock over the 20 consecutive trading days ending three days prior to
    the closing date of the Merger. In the event such increase is necessary, the
    number of shares exchanged will be increased by the number of shares equal
    to the lesser of (A) fifty percent (50%) of the amount obtained from: (1)
    the quotient of $130 million and the Market Price of Access Health Common

To the Holders of Class A and Class B Common Stock of InterQual, Inc.:
 
    The Board of Directors of InterQual, Inc. ("InterQual") has unanimously
approved and is recommending that the holders of InterQual Class A Common Stock
approve the acquisition of InterQual by Access Health, Inc. ("Access Health").
In order to act upon approval of this transaction, InterQual is soliciting the
written consent of the holders of the InterQual Class A Common Stock. InterQual
has set June 30, 1998 as the last date upon which your written consent may be
submitted to InterQual. The written consents of the holders of InterQual Class A
Common Stock should be returned by mail in the enclosed prepaid envelope to the
offices of our counsel, Ropes & Gray, One International Place, Boston,
Massachusetts 02110, Attention: Edward A. Benjamin, or by facsimile: (617)
951-7050.
 
    The holders of InterQual Class A Common Stock will be asked to consent in
writing to a proposal to approve and adopt the Amended and Restated Agreement
and Plan of Reorganization, dated as of June 4, 1998, among Access Health,
Access Acquisition Corp. 98A ("Merger Sub") and InterQual (the "Merger
Agreement"), and to approve the merger (the "Merger") of Merger Sub, a
wholly-owned subsidiary of Access Health, with and into InterQual pursuant to
the Merger Agreement, and to approve the transactions contemplated thereby. Upon
consummation of the Merger, each share of InterQual Class A Common Stock will be
converted into the right to receive the number of shares Access Health Common
Stock equal to the Exchange Ratio (as defined in the Merger Agreement).
 
    In addition, although currently there are no outstanding shares of InterQual
Class B Common Stock, pursuant to the terms of InterQual's 1994 Non-Qualified
Stock Option Plan and the stock option agreements between InterQual and the
holders of options to acquire InterQual Class B Common Stock, the unvested
portion of such options will become fully exercisable immediately prior to the
consummation of the Merger. Any optionholder who chooses to exercise such
options to acquire InterQual Class B Common Stock will become a holder of
InterQual Class B Common Stock immediately prior to the consummation of the
Merger. Each share of InterQual Class B Common Stock will be converted into the
right to receive the number of shares of Access Health Common Stock equal to the
Exchange Ratio multiplied by .99 upon consummation of the Merger.
 
    The Merger Agreement also provides that five percent (5%) of the shares of
Access Health Common Stock issued in the Merger will be placed in escrow for six
months from the closing of the Merger to reimburse Access Health for any
breaches of InterQual's representations and warranties and to satisfy certain
other obligations in the Merger Agreement. Upon completion of the Merger,
InterQual will be a wholly-owned subsidiary of Access Health.
 
    THE BOARD OF DIRECTORS OF INTERQUAL HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, THE MERGER AND THE TRANSACTIONS CONTEMPLATED THEREBY AND RECOMMENDS
THAT THE HOLDERS OF INTERQUAL CLASS A COMMON STOCK CONSENT IN WRITING TO THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT, THE MERGER AND THE TRANSACTIONS
CONTEMPLATED THEREBY.
 
    It is important that the holders of InterQual Class A Common Stock provide
their consent in writing to the Merger Agreement and the Merger. Accordingly, we
ask the holders of InterQual Class A Common Stock please to complete, sign and
date the accompanying form of written consent. The details of the proposed
Merger and the Merger Agreement appear in the accompanying Proxy
Statement/Prospectus and Notice and Consent Solicitation Statement which is
being furnished to the holders of the InterQual Class A and Class B Common Stock
and to the holders of options to purchase InterQual Class B Common
<PAGE>
Stock. You should consider carefully the investment considerations associated
with the Merger discussed under "Risk Factors" in the accompanying Proxy
Statement/Prospectus and Notice and Consent Solicitation Statement. Holders of
InterQual Class A and and any holders of options to acquire Class B Common Stock
who choose to exercise such options pursuant to their terms immediately prior to
the consummation of the Merger are entitled to appraisal rights. See
"Summary--Appraisal Rights," "Approval of the Merger and Related
Transactions--Delaware Appraisal Rights" and Annex D in the accompanying Proxy
Statement/Prospectus and Notice and Consent Solicitation Statement.
 
    The approval and adoption of the Merger Agreement will require the written
consent of the holders of a majority of the outstanding shares of InterQual
Class A Common Stock.
 
                                      Sincerely,

                              ACCESS HEALTH, INC.

                   NOTICE AND CONSENT SOLICITATION STATEMENT
                                       OF
                                INTERQUAL, INC.
 
                           --------------------------
 
    This Proxy Statement/Prospectus of Access Health, Inc., a Delaware
corporation ("Access Health") and Notice and Consent Solicitation Statement of
InterQual, Inc., a Delaware corporation ("InterQual"), is being furnished to the
stockholders of Access Health, in connection with the solicitation of proxies by
the Access Health Board of Directors for use at the Special Meeting of Access
Health Stockholders (including any and all adjournments or postponements
thereof, the "Access Health Special Meeting") to be held at 9:00 a.m., local
time, on June 30, 1998, at Access Health's offices located at 335 Interlocken
Parkway, Broomfield, CO 80021. At the Access Health Special Meeting, holders of
Access Health Common Stock, par value $0.001 per share, will be asked to
consider and vote upon the approval of the issuance of shares of Access Health
Common Stock pursuant to the terms of an Amended and Restated Agreement and Plan
of Reorganization dated as of June 4, 1998 (the "Merger Agreement"), entered
into by and among Access Health, Access Acquisition Corp. 98A, a Delaware
corporation and a newly-formed, wholly-owned subsidiary of Access Health
("Merger Sub") and InterQual.
 
    This Proxy Statement/Prospectus of Access Health and Notice and Consent
Solicitation Statement of InterQual is also being furnished to holders of shares
of Class A and Class B Common Stock of InterQual, par value $1.00 per share, and
the holders of options to purchase Class B Common Stock of InterQual in
connection with the solicitation of written consents by the InterQual Board of
Directors to consider and vote upon the approval and adoption of the Merger
Agreement, pursuant to which, among other things, InterQual would be acquired by
Access Health by means of the merger of Merger Sub with and into InterQual, with
InterQual being the surviving corporation and becoming a wholly-owned subsidiary
of Access Health (the "Merger").
 
    This Proxy Statement/Prospectus of Access Health and Notice and Consent
Solicitation Statement of InterQual constitutes the Prospectus of Access Health
with respect to up to 4,540,000 shares of Access Health Common Stock to be
issued in connection with the proposed Merger. As a result of the Merger, all
outstanding shares of InterQual Class A and Class B Common Stock (collectively,
"InterQual Capital Stock") will be converted into shares of Access Health Common
Stock. The number of shares of Access Health Common Stock to be issued for each
share of InterQual Class A and Class B Common Stock exchanged in the Merger will
depend upon the average closing price of a share of Access Health Common Stock
over the 20 consecutive trading days ending three days prior to the closing date
of the Merger (the "Market Price"). Assuming that the Market Price is at least
equal to $30.3030303 (although there can be no assurance as to the foregoing),
and assuming all outstanding options to purchase InterQual Capital Stock have
been exercised in accordance with their terms, each share of InterQual Class A
Common Stock exchanged in the Merger will be converted into the right to receive
approximately 360.420 shares of Access Health Common Stock and each share of
InterQual Class B Common Stock exchanged in the Merger will be converted into
the right to receive approximately 356.816 shares of Access Health Common Stock.
See "Approval of the Merger and Related Transactions--Manner and Basis of
Converting Shares" and "--Conditions to the Merger." The number of shares
exchanged (the "Merger Consideration") is subject to an increase in the event
that the value of the number of shares of Access Health Common Stock to be
exchanged in the Merger is less than $130 million, computed using the Market
Price. In the event such increase is necessary, the number of shares will be
increased by the number of shares equal to the lesser of (A) fifty percent (50%)
of the amount obtained from: (1) the quotient of $130 million and the Market
Price of Access Health Common Stock, less (2) 4,290,000, and (B) 250,000. In
connection with the Merger, 5% of the shares of Access Health Common Stock
otherwise issuable to holders of InterQual Capital Stock by virtue of the Merger
(the "Escrow Shares") will be placed into escrow and held as security for losses
incurred by Access Health in the event of certain breaches by InterQual of the
covenants, representations or warranties and to satisfy certain other
obligations contained in the Merger Agreement. See "Approval of the Merger and
Related Transactions--Escrow Fund." Holders of InterQual Class A Common Stock
who do not vote in favor of the Merger and holders of InterQual Class B Common
Stock, if any, may, under certain circumstances and by following prescribed
statutory procedures, receive cash for their shares. See "Approval of the Merger
and Related Transactions--Delaware Appraisal Rights." Based upon the number of
shares of Access Health Common Stock issued and outstanding as of May 15, 1998
and assuming a Market Price of at least $30.3030303, and after giving effect to
the issuance of Access Health Common Stock in connection with the Merger
(assuming no exercise of appraisal rights and assuming the release of all of the
Escrow Shares), the former holders of InterQual capital stock would hold
approximately 18.4% of Access Health's total issued and outstanding shares. See

                               PROSPECTUS SUMMARY
 
    The following contains a summary of certain information contained elsewhere
in this Proxy Statement/Prospectus and Notice and Consent Solicitation
Statement. This summary does not contain a complete statement of all material
elements of the proposals to be voted on and is qualified in its entirety by the
more detailed information appearing elsewhere in this Proxy Statement/Prospectus
and Notice and Consent Solicitation Statement and in the information and
documents annexed hereto.
 
THE COMPANIES
 
    ACCESS HEALTH, INC.  Access Health is a leading provider of care management
products and services to the health care industry. Access Health provides its
services primarily through four telephonic care centers, which are staffed by
registered nurses and other health care professionals. Access Health's clients
include health maintenance organizations ("HMOs"), preferred provider
organizations ("PPOs"), indemnity insurers, integrated delivery systems,
government agencies, self-insured employers and physician groups. Access
Health's objective is to measurably improve the delivery of health care through
integrated programs that help individuals effectively manage their health needs.
Its products and services are designed to help reform an inefficient health care
system in ways that benefit health care payors, providers and individuals.
 
    Access Health was founded in 1987 and until 1993 primarily provided consumer
health care information products and services designed to help hospitals and
other health care providers market their services. Beginning in 1993, Access
Health changed its focus to developing, marketing and delivering personal health
management products and services to health plans and payors, which were
primarily designed as a value added member benefit to help attract and retain
members. At the same time, Access Health altered its business model to price its
products and services predominantly on a recurring per-member per-month fee
basis rather than on a non-recurring basis. Access Health enjoyed significant
growth of its personal health management business through mid-1996, at which
point customer demand for care management products which provided demonstrable
cost savings began to intensify. At the time, health care service providers were
experiencing increased price competition and rising medical costs, resulting in
unprecedented high medical loss ratios and lower profitability. In November
1996, Access Health merged with Informed Access Systems, Inc. ("Informed
Access"), a developer of leading-edge clinical assessment tools and care
management programs. With this merger, Access Health significantly expanded its
suite of care management products and substantially enhanced its ability to
provide its customers a demonstrable return on investment.* Also in November
1996, Access Health acquired Clinical Reference Systems, Ltd. ("CRS"), which
develops health information and patient education software programs. Access
Health's care management business has grown dramatically; the number of enrolled
members has increased to approximately 25 million in February 1998 from over 14
million at the end of fiscal 1996.
 
    Access Health was incorporated in California in October 1987 as Referral
Systems Group, Inc., adopted the name Access Health Marketing, Inc. in July
1990, reincorporated in Delaware in January 1992 and changed its name to Access
Health, Inc. in March 1995. Access Health maintains its principal executive
offices at 335 Interlocken Drive, Broomfield, Colorado 80021, and its telephone
number is (303) 466-9500.
 
    INTERQUAL, INC.  InterQual develops and markets clinical decision support
information ("Criteria") which assist health care payors and providers in making
and evaluating level of care and clinical appropriateness decisions. The
Criteria, which are marketed to managed care organizations ("MCOs"), indemnity
insurers, hospitals, integrated delivery systems, physician groups, independent
practice associations, third party administrators and utilization review
organizations, are used after determining patient specific clinical facts and
either signal accord with the physician's choice of a proposed health care
service or indicate a more appropriate alternative. By guiding and documenting
the appropriateness of resource-use decisions, the Criteria are designed to
avoid excessive health care costs and protect against underutilization of needed
services.
 
                                       7
<PAGE>
    InterQual licenses its Criteria either directly to end users or through its
alliance partners program (see "InterQual--Sales and Marketing"). Licensing fees
are payable annually and are based on covered lives, hospital beds or number of
reviews. A substantial majority of InterQual's Criteria products are licensed in
printed form. InterQual's product development efforts are currently addressing
its customers' needs to have the Criteria delivered in electronic form.
InterQual also provides implementation training and consulting services to its
licensees.
 
    InterQual, which is certified by the National Committee for Quality
Assurance as a Credential Verification Organization, also conducts physician and
ancillary health care provider credentialing services for MCOs through its
CredFile-Registered Trademark- software. In addition, InterQual is developing a
Windows-based credentialing product, CredWin-TM-.
 
    InterQual was incorporated in Illinois in 1976 and was reincorporated in
Delaware in 1979. InterQual is headquartered at 293 Boston Post Road West,
Marlborough, MA 01752, telephone (508) 481-1181 and also has an office in North
Hampton, New Hampshire.
 
    ACCESS ACQUISITION CORP. 98A.  Merger Sub is a Delaware corporation recently
organized for the purpose of effecting the Merger. Merger Sub has no material
assets and has not engaged in any activities except in connection with the
Merger.
 
    The principal executive offices of Merger Sub are located at 335 Interlocken
Parkway, Broomfield, Colorado 80021 and its telephone number is (303) 466-9500.

which they exercise voting control FOR the approval of the Share Proposal. See
"Access Health Special Meeting--Vote Required; Quorum."
 
    As of the Access Health Record Date, there were 689 stockholders of record

acquire InterQual Class B Common Stock, the unvested portion of such options
will become fully exercisable immediately prior to the consummation of the
Merger. If such options are exercised in accordance with their terms immediately
prior to the consummation of the Merger, such optionholders will become holders
of InterQual Class B Common Stock immediately prior to the consummation of the
Merger and therefore entitled to all of the rights of stockholders under
Delaware law. See "Solicitation of Written Consents of InterQual
Stockholders--Appraisal Rights" and "Approval of the Merger and Related
Transactions--Delaware Appraisal Rights."
 
    RECORD DATE AND VOTE REQUIRED.  Holders of InterQual Class A and Class B
Common Stock of record at the close of business on May 15, 1998 (the "InterQual
Record Date") are entitled to notice of, and only holders of InterQual Class A
Common Stock are entitled to vote on the matters contained in the Notice and
Consent Solicitation Statement. Under Delaware law and the charter documents of
InterQual, approval and adoption of the Merger Agreement requires the
affirmative vote of holders of a majority of the outstanding shares of InterQual
Class A Common Stock. See "Solicitation of Written Consents of InterQual
Stockholders--Vote Required." Charles M. Jacobs, who beneficially owns
approximately 50.01% of the outstanding InterQual Class A Common Stock has
agreed to vote all such shares in favor of the Merger Agreement. The requisite
approval of the Merger Agreement by the written consent of the holders of
InterQual Class A Common Stock, therefore, is assured.
 
    As of the InterQual Record Date, there were 10,000 shares of InterQual Class
A Common Stock outstanding, no shares of InterQual Class B Common Stock
outstanding, and outstanding options to purchase 1,922 shares of InterQual Class
B Common Stock, the vesting of which will be accelerated in accordance with
their terms at the Effective Time (as defined below). Also, as of such record
date, there were eight stockholders of record of InterQual Class A Common Stock,
and no stockholders of record of InterQual Class B Common Stock.

opinion of Volpe Brown Whelan, which sets forth the assumptions made, procedures

STOCK ARE URGED TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY. See "Approval
of the Merger and Related Transactions--Opinion of InterQual's Financial
Advisor."
 
THE MERGER
 
    EFFECT OF THE MERGER.  At the Effective Time, Merger Sub will be merged with
and into InterQual, the separate corporate existence of Merger Sub will cease
and InterQual will continue as a surviving corporation and as a wholly-owned
subsidiary of Access Health.
 
    Subject to the terms and conditions of the Merger Agreement, as of the
Effective Time, by virtue of the Merger and without any action on the part of
Merger Sub, InterQual or the holder of any shares of InterQual Capital Stock,
the following will occur:
 
    CONVERSION OF INTERQUAL CAPITAL STOCK.  Under the terms of the Merger,
4,290,000 shares of Access Health Common Stock will be exchanged for the
outstanding shares of InterQual Class A and Class B Common Stock. The Merger
Consideration is subject to an increase in the event that the value of the
number of shares of Access Health Common Stock to be exchanged in the Merger is
less than $130 million, computed using the Market Price, which is defined as the
average price per share of Access Health Common Stock over the 20 consecutive
trading days ending three days prior to the closing date of the Merger. In the
event such increase is necessary, the number of shares will be increased by the
number of shares equal to the lesser of (A) fifty percent (50%) of the amount
obtained from: (1) the quotient of $130 million and the Market Price of Access
Health Common Stock, less (2) 4,290,000, and (B) 250,000.
 
    Each share of InterQual Class A Common Stock and each share of InterQual
Class B Common Stock issued and outstanding immediately prior to the Effective
Time (other than any shares held by a holder who has demanded and perfected
appraisal rights for such shares in accordance with the applicable provisions of
the Delaware General Corporation Law (the "DGCL") and who has not withdrawn or
lost such rights ("Dissenting Shares")) will be canceled and extinguished and be
converted automatically, in the case of the InterQual Class A Common Stock into
that number of shares of Access Health Common Stock equal to the Exchange Ratio
(as defined below), and in the case of Class B Common into that number of shares
of Access Health Common Stock equal to the Exchange Ratio multiplied by .99.
InterQual stockholders shall be asked to surrender each certificate representing
InterQual Class A and Class B Common Stock in the manner provided in a letter of
transmittal to be sent to each record holder of InterQual Capital Stock promptly
following the Effective Time (a "Letter of Transmittal"). After the InterQual
stockholders have surrendered such certificates representing shares of InterQual
Class A or Class B Common Stock, as applicable, Access Health will cause to be
issued to such stockholders certificates of Access Health Common Stock
representing their portion of the Merger Consideration, subject to the escrow
provisions of the Merger Agreement described under the section entitled
"Approval of the Merger and Related Transactions--Escrow Fund" below.
 
    The "Exchange Ratio" will be equal to 4,290,000 (subject to adjustment as
described below) divided by the sum of (i) the number of shares of InterQual
Class A Common Stock and (ii) .99 multiplied by the
 
                                       10
<PAGE>
number of shares of InterQual Class B Common Stock outstanding immediately prior
to the Effective Time. If the Market Price is less than $30.3030303, the
numerator in the Exchange Ratio (the "Aggregate Share Number") may be increased
by the number of shares equal to the lesser of (A) fifty percent (50%) of the
amount obtained from: (1) the quotient of $130 million and the Market Price of
Access Health Common Stock, less (2) 4,290,000, and (B) 250,000. Thus, the
Exchange Ratio may vary depending on the Market Price. Assuming that the Market
Price at the Effective Time is at least $30.3030303 per share (although there
can be no assurance as to the foregoing) and assuming all outstanding options to
purchase InterQual Capital Stock have been exercised in accordance with their
terms, the Exchange Ratio will result in each share of InterQual Class A Common
Stock being exchanged for approximately 360.420 shares of Access Health Common
Stock and each share of InterQual Class B Common Stock being exchanged for
approximately 356.816 shares of Access Health Common Stock. For a more detailed
discussion of the calculation of the Exchange Ratio, see "Approval of the Merger
and Related Transactions--Manner and Basis of Converting Shares" below. The
Exchange Ratio will be adjusted to reflect fully the effect of any stock split,
reverse split, stock dividend (including any dividend or distribution of
securities convertible into Access Health Common Stock or InterQual Capital
Stock), reorganization, recapitalization or other like change with respect to
Access Health Common Stock or InterQual Capital Stock occurring after the date
of execution of the Merger Agreement and prior to the Effective Time.
 
    NO FRACTIONAL SHARES.  No fractional shares will be issued by Access Health
in the Merger. Each stockholder of InterQual otherwise entitled to a fractional
share (after aggregating all fractional shares of such stockholder) will receive
an amount of cash (rounded to the nearest whole cent) equal to the product of
(i) such fraction and (ii) the closing price of a share of Access Health Common
Stock on the trading day immediately prior to the closing date of the Merger, as
reported on Nasdaq.
 
    EFFECTIVE TIME OF THE MERGER.  The Merger will become effective upon the
filing of a Certificate of Merger with the Secretary of State of Delaware (the
"Effective Time"). Assuming all conditions to the Merger are met or waived prior
thereto, it is anticipated that the Effective Time will be on or about June 30,
1998.
 
    ESCROW FUND.  In connection with the Merger, at the Effective Time, the
Escrow Shares (defined below) will be registered in the name of and deposited
with The First National Bank of Chicago, as escrow agent (the "Escrow Agent"),
such deposit to constitute the escrow fund (the "Escrow Fund"). The "Escrow
Shares" will be the number of shares of Access Health Common Stock equal to the
product of (i) 0.05 and (ii) the number of shares of Access Health Common Stock
issuable in connection with the Merger. The Escrow Shares will be contributed to
the Escrow Fund on behalf of each holder of InterQual Capital Stock at the
Effective Time in proportion to the aggregate number of shares of Access Health
Common Stock that such holder would otherwise be entitled under the Merger
Agreement. The Escrow Fund will be available to compensate Access Health for any
losses incurred by Access Health or for which Access Health would otherwise be
liable as a result of any inaccuracy or breach of a representation or warranty
of InterQual contained in the Merger Agreement or any failure by InterQual to
perform or comply with any covenant contained therein relating to unresolved
contingencies existing at the Effective Time. The Escrow Fund will also be used
to pay any third party fees and expenses in excess of $4 million ("Excess
Expenses") that have been incurred by InterQual in connection with the Merger
without regard to the Escrow Threshold (defined below). Stockholders will have
voting rights with respect to the Escrow Shares while in escrow, and will
receive dividends, if any, attributable to the Escrow Shares currently, although
in the event that Escrow Shares are to be delivered from the Escrow Fund to
Access Health, any dividends received on such delivered shares shall be returned
to the Escrow Fund for distribution to Access Health. Access Health may not
receive any shares from the Escrow Fund for breach of a representation and
warranty or covenant unless and until cumulative losses in excess of $750,000
(the "Escrow Threshold") have been suffered, in which case Access Health may
recover from the Escrow Fund the entire amount of such cumulative losses. Access
Health may also receive shares from the Escrow Fund to pay for Excess Expenses.
For the purpose of compensating Access Health for its losses or Excess Expenses,
the
 
                                       11
<PAGE>
Escrow Shares will be valued at the closing price of Access Health Common Stock
as reported by the Nasdaq on the trading day prior to the closing date of the
Merger. Subject to resolution of unsatisfied claims of Access Health, the Escrow
Fund will terminate six months following the closing date of the Merger. See
"Approval of the Merger and Related Transactions--Escrow Fund."
 
    BY APPROVING THE MERGER AGREEMENT, INTERQUAL STOCKHOLDERS WILL BE DEEMED TO
HAVE CONSENTED TO THE APPOINTMENT OF CHARLES M. JACOBS, A DIRECTOR AND
STOCKHOLDER OF INTERQUAL, TO ACT AS THE SECURITYHOLDER AGENT ON BEHALF OF
INTERQUAL'S STOCKHOLDERS TO DELIVER SHARES HELD IN ESCROW TO ACCESS HEALTH IN
SATISFACTION OF CLAIMS BROUGHT BY ACCESS HEALTH, TO OBJECT TO SUCH DELIVERIES,
TO AGREE TO, TO NEGOTIATE AND TO ENTER INTO SETTLEMENTS AND COMPROMISES WITH
RESPECT TO SUCH CLAIMS, AND TO TAKE CERTAIN OTHER ACTION ON BEHALF OF
INTERQUAL'S STOCKHOLDERS, ALL AS MORE FULLY DESCRIBED IN ARTICLE VII OF THE
MERGER AGREEMENT. SEE ARTICLE VII OF THE MERGER AGREEMENT FOR A MORE DETAILED
EXPLANATION OF THE ESCROW FUND AND RIGHTS WITH RESPECT THERETO.
 
   
    MARKET PRICE DATA.  Access Health Common Stock has been traded on Nasdaq
under the symbol "ACCS" since Access Health's initial public offering in
February 1992. On February 13, 1998, the last trading day before the
announcement by Access Health and InterQual that they had signed the Merger
Agreement, the closing price of Access Health Common Stock as reported on Nasdaq
was $37.00 per share. Following the Merger, Access Health Common Stock will
continue to be traded on Nasdaq under the symbol "ACCS." On June 8, 1998, the
closing price of Access Health Common Stock as reported on Nasdaq was $25.3125.
There can be no assurance as to the actual price of Access Health Common Stock
prior to, at or at any time following the Effective Time of the Merger. See
"Risk Factors--Volatility of Stock Price" and "Access Health Stock
Information--Access Health Stock Price and Dividend Information."
    
 
    No established trading market exists for InterQual Capital Stock.
 
    REASONS FOR THE MERGER.  In the discussions that led to the signing of the
Merger Agreement, the Access Health Board identified a number of potential
benefits resulting from the Merger. Among the principal benefits identified by
Access Health are the opportunities to: (1) strengthen its position as a leading
care management company*, (2) expand its customer base*, (3) reduce duplicative
investments while pursuing new products and services*, (4) expand management
resources* and (5) realize operational synergies. An additional benefit was the
possibility of achieving long-term operating results accretion.* Notwithstanding
the foregoing expected benefits, the Company does not expect the Merger to be
accretive in terms of earnings per share until fiscal 1999.* The InterQual Board
also identified a number of potential benefits that would accrue to InterQual
and its stockholders as a result of the Merger. These potential benefits include
the opportunity to realize synergies related to the financial, technical, and
sales and marketing resources of the two companies, the opportunity to realize
operational efficiencies, the ability to leverage Access Health's existing
customer base, the opportunity to combine complementary product lines to provide
customers with a more complete product solution, and the enhanced value to
InterQual stockholders from holding publicly traded stock.* See "Approval of the
Merger and Related Transactions--Access Health's Reasons for the Merger" and
"--InterQual's Reasons for the Merger."
 
    CONDUCT OF THE COMBINED COMPANIES FOLLOWING THE MERGER.  Access Health will
maintain the operations of InterQual as a separate operating division of Access
Health. Access Health currently intends to maintain InterQual's operations in
the Marlborough, Massachusetts area. See "Approval of the Merger and Related
Transactions--Consulting and Employee Agreements; Employment Matters." Upon
consummation of the Merger, Douglas L. Elden, a designee of InterQual, will
become a director of Access Health. See "InterQual Management."
 
                                       12

Effective Time, Access Health, acting through The First Chicago Trust Company of
New York as its exchange agent (the "Exchange Agent"), will deliver to each
holder of record of InterQual Class A and Class B Common Stock a letter of
transmittal with instructions to be used by such stockholder in surrendering
certificates which, prior to the Merger, represented shares of InterQual Capital

    AFFILIATE/VOTING AGREEMENTS AND AFFILIATE AGREEMENTS.  Charles M. Jacobs has
entered into an Affiliate/ Voting Agreement with Access Health and InterQual.
Under the Affiliate/Voting Agreement, Mr. Jacobs
 
                                       13
<PAGE>
agrees (i) to restrict sales, dispositions or other transactions reducing his
risk of investment in respect of the shares of InterQual Capital Stock held by
him prior to the Merger and shares of Access Health Common Stock acquired by him
in or after the Merger, subject to a de minimis exception, so as to comply with
the requirements of applicable federal securities laws and to help ensure that
the Merger will be treated as a pooling of interests for accounting and
financial reporting purposes, and (ii) to vote in favor of approval of the
Merger Agreement and the Merger. The vote in accordance with the
Affiliate/Voting Agreement of the shares of InterQual Capital Stock subject to
such Affiliate/Voting Agreement will be sufficient to approve the Merger
Agreement and the Merger by InterQual stockholders. In addition, all other
executive officers and directors of InterQual have executed agreements to
restrict transfers of shares owned or acquired by them, subject to the same de
minimis exception, so as to comply with the requirements of applicable federal
securities laws and to help ensure that the Merger will be treated as a pooling
of interests for accounting and financial reporting purposes.
 
    In addition, each of Access Health's directors and certain executive
officers have executed an Affiliate/Voting Agreement, pursuant to which such
persons agree to (i) restrict sales, dispositions or other transactions reducing
their risk of investment in respect of the shares of Access Health Common Stock
held by them prior to the Merger and shares of Access Health Common Stock
acquired by them after the Merger so as to comply with the requirements of
federal securities laws and to help ensure that the Merger will be treated as a
pooling of interests for accounting and financial reporting purposes, and (ii)
vote in favor of approval of the issuance of the Access Health Common Stock
pursuant to the Merger Agreement.
 
    TERMINATION; TERMINATION FEES.  The Merger Agreement may be terminated under
certain circumstances, including, without limitation, by mutual written consent
of Access Health and InterQual; by either Access Health or InterQual if the
other party commits certain breaches of any representation, warranty or covenant
contained in the Merger Agreement, or if the Merger is not consummated on or
before July 3, 1998; or by InterQual for such time and only during such time
that the average closing price of a share of Access Health Common Stock on
Nasdaq over any 20 consecutive trading days is below $27.14 per share. However,
InterQual's right to terminate the Merger Agreement based on such average
closing price of a share of Access Health Common Stock may be suspended for a
certain time upon specified conditions. See "Approval of the Merger and Related
Transactions--Termination." In the event of termination, each party shall be
liable to the other party under certain circumstances for the following
termination fees.
 
    InterQual will pay Access Health a termination fee of $3.9 million in the
event that the closing of the Merger does not occur, the Merger Agreement is
terminated, Access Health is not in material breach of its obligations under the
Merger Agreement and one of the following events: (i) InterQual has willfully
breached a representation, warranty, covenant or agreement contained in the
Merger Agreement giving rise to a material adverse change in the business,
results of operations or financial prospects of InterQual; (ii) the Merger has
been submitted to a vote of the holders of InterQual Class A Common Stock and
the holders of InterQual Class A Common Stock of InterQual fail to approve the
Merger by the requisite vote; or (iii) the InterQual Board fails to recommend or
changes its recommendation concerning the Merger, or shall disclose, in any
manner, its intention not to recommend or to change such recommendation.
 
    Access Health will pay InterQual a termination fee of $3.9 million in the
event that the closing of the Merger does not occur, the Merger Agreement is
terminated, InterQual is not in material breach of its obligations under the
Merger Agreement, and one of the following events: (i) Access Health has
willfully breached any representation, warranty, covenant or agreement contained
in the Merger Agreement giving rise to a material adverse change in the
business, results of operations or financial prospects of Access Health; (ii)
the Access Health Board fails to recommend or changes its recommendation
concerning the Merger, or discloses, in any manner, its intention not to
recommend or to change its recommendation to stockholders concerning the Merger;
or (iii) the Merger has been submitted to a vote of Access Health's stockholders
and the stockholders of Access Health fail to approve the issuance of shares of
Access Health Common Stock pursuant to the Merger by the requisite vote.
 
                                       14
<PAGE>
    A party's right to the $3.9 million termination fee stated above shall be
such party's sole and exclusive remedy under any of the conditions cited in the
prior two paragraphs, except that if Access Health is entitled to receive such
termination fee, InterQual did not have the right to terminate the Merger
Agreement based on the price of Access Health Common Stock, and InterQual enters
into an agreement or other arrangement with a third party to effect a merger or
similar transaction within six months of the date of termination of the Merger
Agreement, then Access Health will also be entitled to seek any other rights or
remedies under law or equity against InterQual.
 
    CERTAIN FEDERAL INCOME TAX CONSIDERATIONS.  The Merger is intended to
qualify as a reorganization under Section 368(a) of the Code. If the Merger so
qualifies, no gain or loss will generally be recognized by the holders of shares
of InterQual Capital Stock on the exchange of their shares of InterQual Capital
Stock for shares of Access Health Common Stock. Receipt of an opinion by each
company from respective tax counsel that the Merger will constitute a
reorganization under Section 368(a) is a condition to the Merger. HOWEVER, ALL
INTERQUAL STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS. See
"Approval of the Merger and Related Transactions--Certain Federal Income Tax
Considerations."
 
    ACCOUNTING TREATMENT.  The Merger is intended to qualify as a pooling of
interests for financial reporting purposes in accordance with generally accepted
accounting principles. Consummation of the Merger is conditioned upon receipt at
the closing of the Merger by Access Health of letters from Arthur Andersen LLP,
Access Health's independent auditors, affirming the firm's concurrence with
Access Health management's conclusions as to the appropriateness of
pooling-of-interests accounting for the Merger under Accounting Principles Board
Opinion No. 16, if consummated in accordance with the Merger Agreement, and a
letter from Alexander, Aronson, Finning & Co., P.C., InterQual's independent
auditors, as to the appropriateness of pooling-of-interests accounting for a
transaction involving InterQual. See "Approval of the Merger and Related
Transactions--Accounting Treatment."
 
    APPRAISAL RIGHTS.  Holders of InterQual Class A Common Stock who do not vote
by written consent in favor of the Merger and holders of InterQual Class B
Common Stock, if any, may, under certain circumstances and by following
procedures prescribed by the DGCL, exercise appraisal rights and receive cash
for their shares of InterQual Capital Stock. A dissenting stockholder of
InterQual must follow the appropriate procedures under Delaware law or suffer
the termination or waiver of such rights. See "Approval of the Merger and
Related Transactions--Delaware Appraisal Rights." Delaware law does not provide
holders of Access Health Common Stock with any appraisal rights with respect to
the Merger.
 
    INTERESTS OF CERTAIN PERSONS IN THE MERGER.  A condition to the consummation
of the Merger is that certain officers and key employees of InterQual enter into
consulting and employment agreements with Access Health. Furthermore, Francis
Newbury, a director of InterQual, has performed certain financial advisory
services relating to the Merger on behalf of InterQual and will receive a fee of
0.25% of the value of the Merger Consideration from InterQual. See "Approval of
the Merger and Related Transactions-- Interests of Certain Persons in the
Merger."
 
    REGULATORY MATTERS.  Other than compliance with the federal securities laws
and applicable securities laws of the various states, Access Health and
InterQual are aware of no governmental or regulatory approvals required for
consummation of the Merger. Access Health and InterQual have already complied
with the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended. See "Approval of the Merger and Related
Transactions--Governmental and Regulatory Approvals."

(1) Access Health and InterQual estimate that they will incur Merger-related
    expenses of approximately $7 million, consisting primarily of transaction
    costs for financial advisory fees, attorneys, accountants, financial
    printing and one-time charges related to the transaction. This estimate is
    preliminary and is therefore subject to change. These nonrecurring expenses
    will be charged to operations in the fiscal quarter in which the Merger is
    consummated. The Pro Forma Condensed Combined Balance Sheet gives effect to
    such expenses as if they had been incurred as of March 31, 1998, but the Pro
    Forma Condensed Combined Statements of Operations do not give effect to such
    expenses, in accordance with Regulation S-X.
 
(2) All share and per share information has been restated, as applicable, for
    stock splits, as discussed in each entity's respective financial statements
    and notes thereto. In addition, such share and per share information has
    been restated (with regard to Access Health) or presented (with regard to
    InterQual) in accordance with SFAS No. 128 "Earnings per Share" for all
    periods presented. For further discussion of the change in accounting for
    earnings per share, see "Access Health's Management's Discussion and
    Analysis," included herein.

                           COMPARATIVE PER SHARE DATA
 
    The following tables set forth certain historical per share data of Access
Health and InterQual and combined per share data on an unaudited pro forma basis
after giving effect to the Merger on a pooling-of-interests basis assuming the
issuance of 4,290,000 shares of Access Health Common Stock for all outstanding
shares of InterQual Class A and Class B Common Stock (assuming the exercise of
options for InterQual Class B Common Stock in accordance with their terms). The
actual number of shares of Access Health Common Stock to be exchanged for all of
the outstanding InterQual Class A and Class B Common Stock will be determined at
the Effective Time based on the capitalization of InterQual at the Effective
Time. The following data should be read in conjunction with Selected Historical
Financial Data, the Unaudited Selected Pro Forma Condensed Combined Financial
Data, the Unaudited Pro Forma Condensed Combined Financial Statements and the
separate historical financial statements of Access Heath and InterQual included
elsewhere or incorporated by reference herein. The unaudited pro forma combined
per share data are not necessarily indicative of the operating results that
would have been achieved had the Merger been consummated as of the beginning of
the earliest period presented and should not be construed as representative of
future operations. All per share information has been restated, as applicable,
for stock splits, as discussed in each entity's respective financial statements
and notes thereto. In addition, such per share information has been restated
(with regard to Access Health) or presented (with regard to InterQual) in
accordance with SFAS No. 128 "Earnings per Share" for all periods presented. For
further discussion of the change in accounting for earnings per share, see
Access Health's Management's Discussion and Analysis, included herein. No cash
dividends have ever been declared or paid on Access Health Common Stock or
InterQual Class A and/or Class B Common Stock.

(1) Basic historical book value per share is computed by dividing stockholders'
    equity for Access Health and InterQual, respectively, by the number of
    shares of common stock outstanding at the end of each period for Access
    Health and InterQual, respectively. Diluted historical book value per share
    is computed by adjusting basic historical book value per share for dilutive
    securities, determined using the treasury stock method and the fair market
    value as of each date presented. Basic pro forma book value per share is
    computed by dividing pro forma stockholders' equity by the pro forma number
    of shares of common stock outstanding at the end of the period. Diluted pro
    forma book value per share is computed by adjusting basic pro forma book
    value per share for dilutive securities, determined using the treasury stock
    method and the fair market value as of each period presented.
 
(2) This table combines financial information of Access Health for the fiscal
    years ended September 30, 1995, 1996 and 1997 and the six months ended March
    31, 1997 and 1998 with the financial information of InterQual for the years
    ended December 31, 1995, 1996 and 1997 and the six months ended March 31,
    1997 and 1998, respectively.
 
   
(3) Access Health and InterQual have estimated that they will incur
    Merger-related expenses of approximately $9 million, consisting primarily of
    transaction costs for financial advisory fees, attorneys, accountants and
    financial printing and other one-time charges related to the transaction.
    The pro forma combined balance sheet data gives effect to such expenses as
    if they had been incurred as of March 31, 1998; however in accordance with
    Regulation S-X, the pro forma condensed combined statements of operations do
    not give effect to such expenses.
    
 
(4) The unaudited equivalent InterQual pro forma per share amounts are
    calculated by multiplying the Access Health combined pro forma per Access
    Health share amounts by the weighted average Exchange Ratio of 359.839.
 
   
(5) Unaudited pro forma combined book value per share as of September 30, 1997
    is based upon a September 30, 1997 Access Health consolidated balance sheet
    (and giving pro forma effect to estimated Merger-related expenses of $9
    million as if they had been incurred as of September 30, 1997) combined with
    the December 31, 1997 InterQual balance sheet.

                                  RISK FACTORS
 
    The following factors should be considered carefully in evaluating the
proposals to be voted upon by the stockholders of Access Health and consented to
by the stockholders of InterQual and in evaluating an investment in the Access
Health Common Stock offered hereby. For periods following the Merger, references
to the products, business, results of operations or financial condition of
Access Health should be considered to refer to Access Health and its
subsidiaries, including InterQual, unless the context otherwise requires.
 
RISKS RELATED TO THE MERGER
 
    UNCERTAINTIES RELATING TO INTEGRATION OF OPERATIONS MAY AFFECT OPERATING
RESULTS.  Access Health and InterQual have entered into the Merger Agreement
with the expectation that the Merger will result in beneficial synergies for the
combined companies. See "Approval of the Merger and Related Transactions--
Access Health's Reasons for the Merger" and "--InterQual's Reasons for the
Merger." Achieving the anticipated benefits of the Merger will depend in part
upon whether the integration of the two companies' businesses is achieved in an
efficient, cost effective and timely manner, and there can be no assurance that
this will occur. The successful combination of the two companies will require,
among other things, the timely integration of the companies' respective product
and service offerings and the coordination of their respective sales and
marketing and research and development efforts and continuation of key members
of the InterQual management team. The difficulties of such integration may be
increased by the necessity of coordinating geographically separated
organizations. There can be no assurance that integration will be accomplished
smoothly, on time or successfully. Integrating the operations of the two
companies could have a material adverse effect on Access Health's business. For
example, the process could (i) interrupt Access Health's and InterQual's
business, (ii) divert management attention, (iii) place further pressure on
Access Health's officers, and (iv) result in additional administrative and other
expense. Failure to effectively accomplish the integration of the two companies'
operations could have a material adverse effect on Access Health's business,
results of operations and financial condition.
 
    POTENTIAL DILUTIVE EFFECT TO STOCKHOLDERS.  The companies believe that
beneficial synergies will result from the Merger*; however, there can be no
assurance that the combination of the two companies' businesses, even if
achieved in an efficient, effective and timely manner, will result in combined
results of operations and financial condition superior to what would have been
achieved by each company independently, including the results of operations
which each company could have achieved independently in the same period of time.
The issuance of Access Health Common Stock in connection with the Merger is
expected to have the effect of initially reducing Access Health's net income per
share and could reduce the market price of Access Health Common Stock. While the
transaction is not expected to be accretive until fiscal 1999, the degree of
such accretion, if any, will depend on revenue growth, cost savings and/or other
business synergies sufficient to offset the effect of such stock issuance.*
There can be no assurance that such synergies will be achieved. In addition,
there can be no assurance that stockholders of InterQual would not achieve
greater returns on investment if InterQual were to remain an independent
company.
 
    POTENTIAL FLUCTUATION OF THE MERGER CONSIDERATION OR TERMINATION OF MERGER
BASED ON CHANGES OF THE EXCHANGE RATIO.  As a result of the Merger, each share
of InterQual Class A Common Stock will represent the right to receive a number
of shares of Access Health Common Stock equal to the Exchange Ratio, and each
share of InterQual Class B Common Stock will represent the right to receive a
number of shares of Access Health Common Stock equal to .99 multiplied by the
Exchange Ratio. The Exchange Ratio is initially fixed at approximately 360.420
but is subject to adjustment in the event that the Market Price is less than
$30.3030303. Assuming that the Market Price at the Effective Time is at least
$30.3030303 per share (although there can be no assurance as to the foregoing)
and assuming all outstanding options to purchase InterQual Capital Stock have
been exercised in accordance with their terms, the Exchange Ratio will result in
each share of InterQual Class A Common Stock being exchanged for approximately
360.420 shares of Access Health Common Stock and each share of InterQual Class B
Common Stock being exchanged for approximately 356.816 shares of Access Health
Common Stock. If the Market Price is less
 
                                       21
<PAGE>
than $30.3030303, the numerator of the Exchange Ratio will increase by the
number of shares of Access Health Common Stock equal to the lesser of (A) fifty
percent (50%) of the amount obtained from (i) the quotient of $130 million and
the Market Price of Access Health Common Stock, less (ii) 4,290,000, and (B)
250,000. The Exchange Ratio does not adjust further once the Market Price is
less than $27.14, and accordingly, the maximum Exchange Ratio is fixed at
approximately 402.427. Based on such maximum Exchange Ratio, each share of
InterQual Class A Common Stock will be exchanged for approximately 402.427
shares of Access Health Common Stock and each share of InterQual Class B Common
Stock will be exchanged for approximately 398.403 shares of Access Health Common
Stock assuming all options to purchase InterQual Class B Common Stock are
exercised in accordance with their terms. Therefore, any further decrease in the
Market Price below $27.14 will not affect the Exchange Ratio but will reduce the
value for each share of InterQual Class A and Class B Common Stock. The specific
value of the consideration to be received by InterQual stockholders in the
Merger will depend on the market value of Access Health Common Stock at the
Effective Time. In the event that the market value of Access Health Common Stock
decreases or increases prior to the Effective Time, the market value at the
Effective Time of the Access Health Common Stock to be received by the InterQual
stockholders will be affected. While the Merger Agreement is subject to
termination by InterQual in the event that the Market Price is less than $27.14,
there can be no assurance that the InterQual Board will terminate the Merger or
that the holders of InterQual Class A Common Stock will elect to disapprove the
Merger under such circumstances. The market value of Access Health Common Stock
as of a recent date is set forth herein under "Summary--Market Price Data."
InterQual stockholders are advised to obtain recent market quotations for Access
Health Common Stock. Access Health Common Stock historically has been subject to
substantial price volatility. No assurance can be given as to the market value
of Access Health Common Stock at any time before the Effective Time. See "Access
Health Stock Information--Access Health Stock Price and Dividend Information."
 
   
    MATERIAL EXPENSES RESULTING FROM THE MERGER WILL IMPACT RESULTS OF
OPERATIONS.  The combined companies' results of operations will be adversely
affected by Merger-related expenses, consisting primarily of nonrecurring
transaction costs of financial advisors, attorneys, accountants, financial
printing and other related charges estimated to be approximately $8 to $9
million.* These costs will be charged to operations in, and will therefore
negatively impact operating results for, the fiscal quarter in which the Merger
is consummated. Although the companies do not believe that the costs will exceed
these estimates*, there is no assurance that these estimates are correct or that
unanticipated contingencies will not occur that will substantially increase the
costs of combining the operations of the two companies or will result in a
material adverse effect on the results of operations and financial condition of
Access Health in future periods.
    
 
    SHARES ELIGIBLE FOR FUTURE SALE MAY IMPACT MARKET PRICE.  If the Merger is
consummated, Access Health will issue to stockholders of InterQual an aggregate
of approximately 4,290,000 shares of Access Health Common Stock (subject to an
increase of up to 250,000 shares as described above). Substantial sales of such
shares of Access Health Common Stock are likely to occur after the Merger.
Immediately upon consummation of the Merger, approximately 787,800 of such
shares will be freely tradeable. Following publication of financial results
covering 30 days of post-Merger combined operations, approximately 3,502,200
additional shares issued in the Merger to persons who may be deemed affiliates
of InterQual could be publicly sold pursuant to Rule 145 under the Securities
Act, subject to the volume and other limitations thereof, and of these
additional shares issued to affiliates, 1,000,000 shares will be subject to
immediate resale under the registration statement filed in connection herewith
pursuant to Rule 415 under the Securities Act. In addition, following such
publication of financial results, a substantial number of the shares of Access
Health Common Stock issued in the Merger to InterQual affiliates are likely to
be sold pursuant to the exercise of registration rights. See "Approval of the
Merger and Related Transactions--Registration Rights Agreement." Future sales of
a substantial number of such shares of Access Health Common Stock could
adversely affect or cause substantial fluctuations in the market price of Access
Health Common Stock.

RISKS RELATED TO ACCESS HEALTH BUSINESS
 
    UNCERTAINTY RELATED TO OBTAINING, EXPANDING AND RETAINING CONTRACTS MAY
IMPACT RESULTS OF OPERATIONS. Access Health's ability to increase revenues and
profitability is largely dependent on Access Health's ability to secure
additional care management contracts and to retain and expand existing
contracts. Access Health could be adversely affected by the termination or
non-renewal of any of Access Health's contracts, or by renegotiation of the
terms of the contacts, particularly if the affected contracts cover a large
number of members or represent a significant portion Access Health's care
management revenue. For example, in fiscal 1997, Access Health renegotiated
various older care management contacts to bring price terms based on minimum
membership and utilization rates previously negotiated in line with actual
membership and utilization rates. Such rationalizations resulted in a decrease
of revenue by approximately $7.0 million in fiscal 1997. During the first half
of fiscal 1998 contract rationalizations decreased revenue by approximately $2.7
million and for the balance of the year the Company expects contract
rationalizations to reduce revenue under such contracts by approximately $3.2
million. Any factors adversely affecting the market for Access Health's care
management products or licensing and support services products, including
factors outside of Access Health's control, such as adverse publicity or
government regulatory action, could have a material adverse effect on Access
Health.
 
    DEPENDENCE ON PRINCIPAL CUSTOMERS.  Significant portions of Access Health's
revenues are generated by a limited number of customers. Access Health's care
management contracts range from approximately 800 members to 3.0 million members
per contract. In fiscal 1997, the five largest single care management
enrollments totaled 3.0 million, 2.4 million, 1.9 million, 1.5 million and 1.5
million members. In fiscal 1997, Access Health's three largest customers
accounted for approximately 8.0%, 7.8%, and 6.9% of Access Health's total
revenues and Access Health's top five customers, in the aggregate, accounted for
approximately 33.4% of Access Health's total revenues. After an initial term of
approximately one to four years, contracts generally can be terminated upon 60
to 360 days notice to Access Health. Three of Access Health's five largest
contracts are up for renewal in the second half of fiscal 1998. Access Health's
contracts could be subject to early termination by its customers if Access
Health were not in compliance with any applicable government regulation. The
termination, non-renewal or renegotiation of any such agreements could have a
material adverse effect on Access Health's operating results. See "Access Health
Business--Government Regulation."
 
    UNCERTAINTY OF FUTURE OPERATING RESULTS.  Access Health's quarterly
operating results may fluctuate significantly in the future as a result of a
variety of factors, many of which are outside Access Health's control. There can
be no assurance that Access Health's revenues and profitability will increase
during fiscal 1998 and beyond. Access Health's revenues may be materially
adversely affected by the termination or non-renewal of Access Health's
contracts or by the renegotiation of the terms of such contracts. Access Health
may incur significantly increased sales, marketing, and promotional expenses
during fiscal 1998, and may devote additional resources to the further
development of care management, disease management or other new products. To the
extent that Access Health incurs increased expenses, Access Health's operating
results will be adversely affected unless revenues and operating margins
increase sufficiently to offset such expenditures of which there can be no
assurance. See "Access Health--Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
    CHANGING HEALTH CARE MARKET COULD CAUSE NEW PRODUCT DEVELOPMENT AND OTHER
COSTS TO INCREASE; ABILITY TO ADAPT TO CHANGE.  The health care industry has
undergone significant changes in recent years, and changes are expected to
continue. Containing health care costs has become a national priority. As a
result, the health care industry has become increasingly dominated by managed
health care plans, causing cost containment pressure to rise. To address these
changes, Access Health shifted its business focus in 1993 to payors from
providers and developed its personal health management services. There is no
assurance that Access Health's existing products and services will achieve
continued success or that its new products and services will succeed. There also
can be no assurance that continued industry change will not adversely affect
Access Health's ability to compete. Continued change may cause Access Health to
incur significant product development and marketing expenses which could have a
material effect on operations.
 
                                       23
<PAGE>
Access Health's future success will depend on Access Health's ability to adapt
to the changing needs of the health care industry.
 
    DEPENDENCE ON ADEQUATE FUNCTIONING OF CARE CENTER OPERATIONS.  Access Health
maintains member service and data centers ("care centers") in Rancho Cordova,
California; Chicago, Illinois; Broomfield, Colorado; and Phoenix, Arizona.
Access Health's operations depend on the adequate functioning of the computer
and telephone systems in its call centers. Although Access Health has taken
precautions to provide for power, computer, and telephone systems redundancy,
there can be no assurance that a fire or other disaster affecting the centers or
an equipment failure would not disable Access Health's systems for a significant
period of time. Any significant damage to Access Health's facilities or an
equipment failure could have a material adverse effect on Access Health's
results of operations.
 
    The successful operation of Access Health's care centers is based on a
networked information system. The information system provides care center nurses
and health care counselors with access to care management applications and a
database of information including member information, plan rules, physician
information and clinical algorithms and guidelines. Access Health is in the
process of developing a new information system which combines certain aspects of
the different systems developed by Access Health and Informed Access. Failure to
successfully develop and implement this new information system could delay
revenues or increase operating costs and could have a material adverse effect on
Access Health. The ability to continue to develop, implement and support Access
Health's information systems is dependent on its ability to employ and retain
experienced technical personnel. If Access Health is unable to hire and retain
required personnel or is required to pay compensation at significantly higher
levels to attract and retain technical personnel it could have a material
adverse effect on Access Health's financial results.
 
    ACQUISITION-RELATED RISKS MAY ADVERSELY AFFECT OPERATIONS AND FINANCIAL
RESULTS.  Access Health has grown in part through mergers and acquisitions.
Access Health intends to evaluate acquisitions of product lines and businesses
as part of its business strategy. The process of integrating an acquired
company's business into Access Health's operations may result in unforeseen
operating difficulties and expenditures and may absorb significant management
attention that would otherwise be available for the ongoing development of
Access Health's business. Moreover, there can be no assurance that the
anticipated benefits of an acquisition will be realized. Future acquisitions by
Access Health could result in potentially dilutive issuances of equity
securities, the incurrence of debt and contingent liabilities and amortization
expenses related to goodwill and other intangible assets, which could materially
adversely affect Access Health's operating results and financial condition. In
addition, acquisitions involve numerous risks, including difficulties in
managing diverse geographic operations, the diversion of management's attention
from other business concerns, risks of entering markets in which Access Health
has no or limited direct prior experience and the potential loss of key
employees of the acquired company. The inability of Access Health's management
to respond to changing business conditions effectively, including the changes
associated with its acquired businesses and product lines, could have a material
adverse effect on Access Health's business, results of operations and financial
condition.
 
    VOLATILITY OF STOCK PRICE.  The market for Access Health's stock is highly
volatile. The trading price of Access Health's Common Stock is subject to wide
fluctuations in response to a variety of factors including the signing or loss
of a major contract, changes in market analyst estimates and recommendations for
Access Health's Common Stock, fluctuations in operating results, the failure of
operating results to meet market analyst's estimates, changes in government
regulation and general conditions in the health care industry and the economy,
any of which could cause the price of Access Health's Common Stock to fluctuate,
perhaps substantially. In addition, in recent years stock prices have
experienced significant fluctuations, which have particularly affected the
market price for the securities of health care companies and which often have
been unrelated to the operating performance of these companies.
 
                                       24

RISKS RELATED TO INTERQUAL BUSINESS
 
    EACH OF THE FOLLOWING RISKS RELATING TO INTERQUAL WILL CONTINUE TO BE RISKS
FACED BY THE COMBINED INTERQUAL AND ACCESS HEALTH COMPANIES IN THE FUTURE SINCE
ACCESS HEALTH INTENDS TO CONTINUE THE OPERATIONS OF INTERQUAL AS A SEPARATE
OPERATING SUBSIDIARY FOLLOWING THE MERGER. SINCE INTERQUAL'S REVENUES WILL
ACCOUNT FOR A MATERIAL PORTION OF ACCESS HEALTH'S TOTAL REVENUES FOLLOWING THE
MERGER, IN THE EVENT THAT ANY OF THE FOLLOWING INTERQUAL RISKS MATERIALLY
IMPACTS INTERQUAL'S FINANCIAL RESULTS, SUCH RISKS MAY IN TURN HAVE A MATERIAL
ADVERSE EFFECT ON ACCESS HEALTH'S BUSINESS, RESULTS OF OPERATION OR FINANCIAL
CONDITION.
 
    DEPENDENCE ON ANNUAL LICENSE RENEWALS.  InterQual's Criteria are licensed on
an annual and multi-year basis. While InterQual has realized high historic
renewal rates in recent years, there can be no assurance that future renewal
rates will be maintained at historic levels. A significant reduction in the
number of customers who choose to renew their licenses with InterQual could
materially adversely affect InterQual's business, results of operations and
financial condition.
 
    ABILITY TO MEET TECHNOLOGICAL DEMANDS OF THE MARKETPLACE.  The market for
health care information systems for data analysis is characterized by continual
change and improvement in computer hardware and software technology. Currently,
however, InterQual derives a substantial majority of its revenues from license
fees for its Criteria delivered in print (book) format. InterQual believes a
principal challenge is providing clinical knowledge in a form that addresses its
customers' needs. The delivery of Criteria and clinical knowledge in electronic
form is becoming increasingly important in light of the increased automation and
technological advances in the health care information systems industry. In
response to such industry changes, InterQual has developed (i) a stand-alone
computerized delivery vehicle for its Criteria (AutoBook-TM-) and (ii) software
for interfacing AutoBook-TM- to client and to third party health information
systems. In addition, InterQual is actively developing additional methods to
deliver its Criteria and clinical knowledge pursuant to partnerships with third
party providers of health care information systems and end-users. InterQual
believes that as the market for care management systems matures, heightened
competition will require InterQual to enhance its current systems, to introduce
new software that keeps pace with technological developments and to develop new
applications that address the needs of its clients. There can be no assurance
that (i) InterQual or its health care technology partners will be successful in
developing and marketing enhancements or new Criteria delivery system
applications, (ii) InterQual's Criteria delivery systems will continue to
address adequately the needs of the marketplace or (iii) InterQual will be able
to form partnerships in the future with third parties who can provide such
software applications. If InterQual's Criteria delivery systems do not perform
substantially as expected or are not accepted in the marketplace, InterQual's
business, results of operations and financial condition could be materially
adversely affected. In addition, the Criteria delivery systems embodying new
technologies or the emergence of new industry standards could render InterQual's
existing Criteria delivery systems and services obsolete and unmarketable.
 
    SYSTEM AND DATA DEFECTS.  The clinical content, print and software delivery
systems and primary source verification service of InterQual and its health care
technology partners are complex and sophisticated and could from time to time
contain clinical errors, data errors or design defects that could be difficult
to detect and correct and result in loss of or delay in market acceptance or
loss of reputation. Although InterQual has not to date experienced material
adverse effects resulting from any clinical or software errors or defects, there
can be no assurance that, despite testing by InterQual and its customers, errors
will not be found in existing or new Criteria delivery systems. Any clinical or
software errors or defects in existing or new Criteria delivery systems could
result in a delay in, or inability to achieve, market acceptance, and
InterQual's business, results of operations and financial condition could be
materially adversely affected.
 
    DEPENDENCE ON CONTINUED CERTIFICATION AS A CREDENTIALS VERIFICATION
ORGANIZATION.  The ability of InterQual to continue to compete for primary
source verification ("PSV") contracts depends on its maintenance of
certification as a credentials verification organization ("CVO"). Currently,
InterQual is fully certified by the National Committee for Quality Assurance
("NCQA") for 10 out of 10 verification services. However, as a result of the
Merger, NCQA will have the right to conduct a discretionary review of
 
                                       25
<PAGE>
InterQual to determine whether a change in InterQual's certification status is
warranted. In addition, as of May 1998 the American Accreditation HealthCare
Commission/URAC ("AAHC/URAC") has launched a program for CVO accreditation.
Failure of InterQual to maintain its NCQA certification or to obtain
certification from AAHC/URAC or any future accrediting organization may have a
material adverse effect on InterQual's ability to compete for PSV contracts and
its financial position and results of operations.
 
    DEPENDENCE ON DEPARTMENT OF DEFENSE MANDATE.  The Department of Defense has
mandated that health plans providing health care services under the CHAMPUS
program use InterQual's Criteria products. In 1997, 5.2% of InterQual's total
revenues were received pursuant to such mandate. Any termination or modification
of the Department of Defense's mandate could have a material adverse effect on
InterQual and its business, financial condition and operating results.
 
    DEPENDENCE ON DECEMBER QUARTER RENEWALS.  Historically, InterQual has
realized disproportionately higher annual customer renewals in the December
quarter of each fiscal year. For example, contracts representing 47% of total
renewal revenues were renewed in the December quarter of calender 1997.
InterQual expects this pattern to continue due primarily to its contract renewal
cycle and customer budgeting and purchasing patterns.* Any factors negatively
affecting InterQual during the December quarter in any year, including the
failure of customers to renew their licenses, could have a material adverse
effect on InterQual's business, results of operations and financial condition.
 
RISKS COMMON TO BOTH ACCESS HEALTH AND INTERQUAL BUSINESSES
 
    ANY OF THE RISKS RELATING TO BOTH ACCESS HEALTH AND INTERQUAL IN THE
FOLLOWING SECTION WILL CONTINUE TO BE RISKS FACED BY THE COMBINED INTERQUAL AND
ACCESS HEALTH COMPANIES IN THE FUTURE. SINCE INTERQUAL'S REVENUES WILL ACCOUNT
FOR A MATERIAL PORTION OF ACCESS HEALTH'S TOTAL REVENUES FOLLOWING THE MERGER,
IN THE EVENT THAT ANY OF THE FOLLOWING RISKS COMMON TO ACCESS AND INTERQUAL
MATERIALLY IMPACTS INTERQUAL'S FINANCIAL RESULTS, SUCH RISKS MAY IN TURN HAVE A
MATERIAL ADVERSE EFFECT ON THE COMBINED COMPANIES' BUSINESS, RESULTS OF
OPERATION OR FINANCIAL CONDITION.
 
    HIGHLY COMPETITIVE MARKET.  The markets for the products and services of
Access Health and InterQual are highly competitive. There are a number of
competitors that offer products or services that compete with some or all of
those offered by Access Health and by InterQual. Existing and potential clients
may also evaluate Access Health's and InterQual's products or services against
internally developed programs. Increased competition could result in pricing
pressure and margin erosion. In their existing businesses and as Access Health
and InterQual each offers new products or services, or enters new markets, they
may each face increased competition from competitors, some of whom may have
substantially greater financial, marketing and technical resources. In
particular, several smaller competitors of Access Health have recently been
acquired or are expected to be acquired by companies with substantially greater
financial, marketing and technical resources than Access Health. There can be no
assurance that Access Health or InterQual will continue to compete successfully.
 
    LIMITATIONS ON PROTECTION OF PROPRIETARY RIGHTS.  Access Health and
InterQual both regard their proprietary rights as essential to their respective
businesses and take action to protect their intellectual property with patents,
copyrights, trademarks, trade secret laws and restrictions on disclosure,
copying and transferring title. Proprietary items of Access Health include its
software, clinical algorithms and nursing assessment tools, clinical operational
expertise and marketing and program operation materials. InterQual regards its
Criteria, credential protocols, software, clinical and administrative decision
support operational expertise, marketing and program operational materials as
proprietary. Despite precautions, it may be possible for unauthorized third
parties to copy aspects of the products of Access Health or InterQual or to
obtain and use information that the companies regard as proprietary.
 
    There can be no assurance that competitors, some of which have substantial
resources and have made substantial investments in competing technologies, will
not seek to apply for and obtain patents that will prevent, limit or interfere
with the ability of Access Health or InterQual to market their respective
products and services either in the United States or in international markets.
Litigation may be necessary in the future to enforce intellectual property
rights, to protect trade secrets of Access Health and/or
 
                                       26
<PAGE>
InterQual, to determine the validity and scope of the proprietary rights of
others, or to defend against claims of infringement or invalidity. Such
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on Access Health and InterQual businesses,
operating results or financial conditions. Access Health has been issued patents
on its clinical algorithms in the United States and has filed for patent
protection in some foreign countries. InterQual has applied for a U.S. patent
for its AutoBook-TM- product. There is no assurance that such patents will not
be challenged or invalidated. Existing copyright laws afford only limited
practical protection. In addition, the laws of some foreign countries do not
protect Access Health's and InterQual's proprietary rights to the same extent as
do the laws of the United States.
 
    DEPENDENCE ON KEY EMPLOYEES AND MANAGEMENT OF CHANGE.  The success of both
Access Health and InterQual depends in part on the continued contributions of
certain key management employees, most of whom are subject to noncompetition
restrictions. The loss of the services of one or more of these employees could
have a material adverse effect on the combined companies' businesses, financial
positions and results of operations. Both Access Health and InterQual believe
that their continued success also will depend in large part on their ability to
attract and retain highly-skilled management, technology, marketing, sales and
physician and nursing personnel. Competition for such personnel is intense, and
there can be no assurance of success in attracting and retaining such personnel
as necessary. Furthermore, the ability to manage change and growth successfully
will require continued improvement of the companies' respective management
expertise as well as their financial systems and controls.
 
    NEED TO CONTINUE TO MANAGE GROWTH OF OPERATIONS.  Both Access Health and
InterQual have experienced rapid growth in recent years. Continued rapid growth
may place a significant strain on management, telecommunications systems,
operational infrastructure, working capital and financial and management control
systems. The difficulties of managing growth may be increased by the necessity
of coordinating geographically separated organizations. In order for Access
Health and InterQual to manage their respective client bases successfully,
management will be required to anticipate the changing demands of their growing
operations and to adopt systems and procedures accordingly. Failure to
effectively implement or maintain such systems and procedures could adversely
affect the combined businesses, results of operation and financial conditions of
Access Health and InterQual. Further, there can be no assurance that the current
information systems, telecommunications systems and operational infrastructures
of Access Health and InterQual will be adequate for the future needs of the
combined companies, or that Access Health or InterQual will be successful in
implementing new systems. Failure to upgrade the information systems,
telecommunications systems and operational infrastructure or unexpected
difficulties encountered with these systems during expansion could adversely
affect the businesses, financial conditions and results of operations of Access
Health or InterQual.
 
    GOVERNMENT REGULATION.  The health care industry is subject to extensive and
evolving government regulation at both federal and state levels relating to many
aspects of Access Health's business, InterQual's business, and the use of Access
Health's programs and InterQual's products and services by their respective
clients, including the provision and review of health care services,
teleservicing, health care referral programs and the process for selecting and
retaining individual professionals on provider panels and HMOs and other similar
plans.
 
    In the case of Access Health, the literal language of certain of these
statutes and regulations governing the provision of health care services,
including the practice of nursing and the practice of medicine, could be
construed by regulatory authorities to apply to certain activities, including
without limitation teleservicing activities which use California, Illinois,
Arizona, and Colorado registered nurses to provide out-of-state care management
services such as nursing assessments and information regarding appropriate
sources of care and treatment time frames, or to apply to certain activities of
Access Health that are provided on a per-member, per-month basis. These statutes
and regulations could also apply to certain activities of Access Health's health
service customers when operating Access Health's programs. Access Health
understands that state regulators in some states have informed some entities
that they are adopting such a construction. Access Health has taken steps to
comply with such regulatory interpretations, but there can
 
                                       27
<PAGE>
be no assurance that such steps will be sufficient to protect Access Health from
the effects of such regulatory action. The literal language of the statutes and
regulations, in the case of InterQual, could also be construed by regulatory
authorities to apply to development and use of certain of InterQual's products,
including without limitation, the use of out-of-state licensed physicians and/or
registered nurses to develop medical review Criteria and information regarding
appropriate sources of and types of care or to certain activities of InterQual's
health service customers when using InterQual's products for preauthorization
and other medical care review. InterQual has complied with all such regulatory
requirements of which it is aware.
 
    While some states have indicated their intention to interpret their statutes
to require licenses for out-of-state providers, most states have not addressed
this issue by regulation or state legislation. However, if regulators seek to
enforce any of the foregoing statutory and regulatory requirements, Access
Health, InterQual, their employees and/or their clients could be required to
obtain additional licenses or registrations, to modify or curtail the use and
operation of Access Health's programs and/or InterQual's products, to modify the
method of payment for Access Health's programs and/or InterQual's products, or
to pay fines or incur other penalties.
 
    The payment of remuneration to induce the referral of health care business
has been a subject of increasing governmental and regulatory focus in recent
years. Section 1128B(b) of the Social Security Act (sometimes referred to as the
"Federal anti-kickback statute") provides criminal penalties and civil damages
for individuals or entities that knowingly and willfully offer, pay, solicit or
receive remuneration in order to induce referrals for items or services for
which payment may be made under the Medicare and Medicaid programs and certain
other government-funded programs. The Social Security Act also provides
authority to the Office of the Inspector General, through civil proceedings, to
exclude an individual or entity from participation in the Medicare and state
health programs if it is determined any such party has violated Section 1128B(b)
of the Social Security Act. Regulations have been promulgated specifying certain
payment practices that will not be subject to criminal prosecution, civil
penalties nor exclusion. These regulations, commonly referred to as the "safe
harbor" regulations, do not expand the scope of the Federal anti-kickback
statute, and the fact that a business arrangement does not fit within a safe
harbor does not necessarily mean the business arrangement violates the Federal
anti-kickback statute.
 
    Access Health's programs involve payment for referral services and do not
meet all of the requirements of the applicable safe harbor for referral
services. In addition, a number of states in which Access Health and InterQual
operate have anti-kickback statutes similar to the Federal statute, as well as
statutory and regulatory requirements governing referral agencies and regulating
franchising and business opportunity ventures. The Federal government and a
number of states have enacted statutes which contain outright prohibitions on
referrals for specified services which are made by referring providers who have
an ownership interest in, or compensation arrangement with, the entity to which
the referral is made. If Access Health or the use of its products and services
were to be found in violation of such statutes, Access Health or its clients
could be required to modify or curtail the operation of Access Health's
programs, or to pay fines or incur other penalties, and Access Health's clients
could be excluded from participation in federal health care programs including
the Medicare and Medicaid programs and could be precluded from charging fees and
obtaining reimbursement for specified services.
 
    InterQual believes that its products and the use of its products by its
licensees do not violate the anti-kickback statutes, but believes that the use
by its clients may not meet the safe harbor requirements. However, the Federal
government and a number of states have enacted or are planning to enact statutes
which (i) contain outright prohibitions on referrals for specified services
which are made by referring providers who have an ownership interest in, or
compensation arrangement with, the entity to which the referral is made, (ii)
mandate that medical review decisions such as those facilitated by use of
InterQual's products are subject to appeal or other grievance procedures or
(iii) impose liability on MCOs or their physician reviewers for alleged patient
harm resulting from medical review decisions. If InterQual or the use of its
products by customers or Access Health were to be found in violation of such
statutes or to fall within the requirements of such statutes, Access Health,
InterQual or their clients could be required to modify the mode of development
and/or use of InterQual's products, or to pay fines or incur substantial
 
                                       28
<PAGE>
expense or other penalties, and InterQual's clients could be excluded from
participation in federal health care programs, including the Medicare and
Medicaid programs and could be precluded from charging fees and obtaining
reimbursement for specified services.
 
    There can be no assurance that Access Health, InterQual, or the use of
either company's products and services will not be subject to review or
challenge by government regulators under any of the foregoing statutes and
regulations. Access Health has also started to offer utilization management
services, which services are subject to specific state regulations and licensing
requirements that may prove difficult and costly for Access Health to comply
with. In addition, additional laws and regulations could be enacted in the
future that would regulate Access Health, InterQual, or the use of each
company's, or the combined companies', products and services. Any government
investigative or enforcement actions with respect to Access Health, InterQual or
the use of their respective products or services could generate adverse
publicity irrespective of the final outcome, and could have a material adverse
effect on Access Health, InterQual, their businesses, financial conditions and
results of operations. The use or required use of Access Health or InterQual
clinical criteria could be subject to opposition from organized providers or
consumer groups, which could lead to adverse legislation, regulation or
publicity.
 
    RISK MANAGEMENT.  In recent years, participants in the health care industry,
including physicians, nurses and other health care professionals, have been
subject to an increasing number of lawsuits alleging malpractice, product
liability and related legal theories, many of which involve large claims and
significant defense costs. Due to the nature of its business, Access Health
could become involved in litigation regarding the telephone information given by
its registered nurses or those of its licensees with the risk of adverse
publicity, significant defense costs and substantial damage awards. Similarly,
InterQual could become involved in litigation regarding the medical reviews
conducted by its customers or the credentialing decisions made by its customers
or by Access Health with the same risk of adverse publicity, significant defense
costs and substantial damage awards.
 
    Access Health has established policies and procedures that limit the
information provided by its registered nurses to that contained in its clinical
algorithms and protocols and in other approved reference sources. In connection
with its teleservices operations, Access Health has a quality assurance program
that includes real-time audits of calls and post call reviews to monitor
compliance with established policies and procedures. Generally, clients review
and approve Access Health's clinical algorithms, protocols and guidelines prior
to program implementation and do not modify them without medical approval. To
date, Access Health has not been the subject of any claim involving either its
clinical assessment systems, the operation of its teleservicing centers or the
operation by hospital or other clients of on-site call centers nor has InterQual
been the subject of any claim involving the use of its clinical Criteria or the
data it has provided through its credentialing service. However, there can be no
assurance that claims will not be brought against Access Health, InterQual, or
the combined companies in connection with the medical review business. Even if
such claims ultimately prove to be without merit, defending against them can be
time consuming and expensive, and any adverse publicity associated with such
claims could have a material adverse effect on Access Health, InterQual, their
businesses, financial conditions and results of operations. Further, there can
be no assurance that Access Health or InterQual has appropriate or sufficient
coverage under their existing insurance plans or that they will be able to
obtain appropriate or sufficient amounts of insurance in the future to address
the foregoing risks on terms that are commercially reasonable.
 
    IMPACT OF THE YEAR 2000 ON COMPUTER SYSTEMS.  The architectural design of
both Access Health's and InterQual's computer systems and infrastructure have
taken into account the effect of integrating existing date data with date data
from the Year 2000 and beyond. As a result, each company believes it will
address and resolve any possible issue associated with the integration of Year
2000 date data in a timely fashion and will not materially affect future
financial results or cause reported financial information to be inaccurate.*
Nevertheless, unforeseen internal problems or unanticipated events including the
inability of third party vendors to integrate Year 2000 date data could occur
causing a material adverse effect on the Access Health's and/or InterQual's
businesses, results of operation and financial condition.

    This Proxy Statement/Prospectus and Notice and Consent Solicitation
Statement is (i) furnished in connection with the solicitation of proxies by the
Access Health Board to be used at the Access Health Special Meeting and (ii)
furnished to holders of InterQual Class A and Class B Common Stock and holders
of options to purchase InterQual Class B Common Stock in connection with the
solicitation of written consents of the InterQual Class A Common Stock by the
InterQual Board and to provide notice to the holders of InterQual Class B Common
Stock and the holders of options to purchase InterQual Class B Common Stock.
This Proxy Statement/Prospectus and Notice and Consent Solicitation Statement is
also furnished by Access Health to InterQual stockholders and optionholders in
connection with the issuance of shares of Access Health Common Stock in
connection with the Merger described herein.
 
    The information set forth herein concerning Access Health has been furnished
by Access Health and the information set forth herein concerning InterQual has
been furnished by InterQual.
 
                         ACCESS HEALTH SPECIAL MEETING
 
DATE, TIME AND PLACE OF ACCESS HEALTH SPECIAL MEETING
 
    The Access Health Special Meeting will be held on Monday, June 30, 1998 at
9:00 a.m., local time, at Access Health's executive offices located at 335
Interlocken Parkway, Broomfield, Colorado 80021.
 
PURPOSES OF ACCESS HEALTH SPECIAL MEETING
 
    The purpose of the Access Health Special Meeting is to consider and vote
upon the approval of the issuance of shares of Access Health Common Stock
pursuant to the terms of the Merger Agreement. As a result of the Merger, all
outstanding shares of InterQual Capital Stock will be converted into shares of
Access Health Common Stock. See "Approval of the Merger and Related
Transactions--Manner and Basis of Converting Shares."
 
RECORD DATE AND OUTSTANDING SHARES
 
    Only stockholders of record of Access Health Common Stock at the close of
business on the Access Health Record Date, which is May 15, 1998, are entitled
to notice of, and to vote at, the Access Health Special Meeting. As of the
Access Health Record Date, there were approximately 689 stockholders of record
holding an aggregate of 18,993,742 shares of Access Health Common Stock.
 
VOTE REQUIRED; QUORUM
 
    Because the number of shares of Access Health Common Stock to be issued or
reserved for issuance in connection with the Merger will exceed 20% of the
number of shares of Access Health Common Stock outstanding prior to the Merger,
approval by a majority of the votes cast at the Access Health Special Meeting of
the issuance of the Access Health Common Stock pursuant to the Merger Agreement
is required under the rules of the Nasdaq. If a majority of the votes cast at
the Access Health Special Meeting do not approve such issuance, the Merger will
not be consummated. In such event, Access Health will be obligated to pay a
termination fee of $3.9 million to InterQual. Each stockholder of record of
Access Health Common Stock on the Access Health Record Date is entitled to cast
one vote per share, exercisable in person or by properly executed proxy, on each
matter properly submitted for the vote of the stockholders of Access Health at
the Access Health Special Meeting.
 
    The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Access Health Common Stock entitled to
vote at the Access Health Special Meeting will constitute a quorum. If an
executed Access Health proxy is returned and the stockholder has specifically
abstained from voting on any matter, the shares represented by such proxy will
be considered present at the Access Health Special Meeting for purposes of
determining a quorum and for purposes of calculating the vote, but will not be
considered to have been voted in favor of such matter. If an executed proxy is
 
                                       30
<PAGE>
returned by a broker holding shares in street name which indicates that the
broker does not have discretionary authority as to certain shares to vote on one
or more matters (a "broker non-vote"), such shares will be considered present at
the meeting for purposes of determining a quorum, but will not be considered to
be represented at the meeting for purposes of calculating the votes cast with
respect to such matter. Abstentions and broker non-votes will have no effect on
the Share Proposal.
 
    Certain holders of Access Health Common Stock have entered into
Affiliate/Voting Agreements with Access Health, pursuant to which each such
holder has agreed to vote (i) in favor of approval of the issuance of the shares
of Access Health Common Stock pursuant to the Merger Agreement and (ii) against
(among other things) approval of any proposal made in opposition to or
competition with consummation of the issuance of shares in connection with the
Merger. In addition, each such holder has granted pursuant to such holder's
Affiliate/Voting Agreement, to each director on the Board of Directors of Access
Health, an irrevocable proxy to vote shares as aforesaid. These shares of Access
Health Common Stock subject to the Affiliate/Voting Agreement represent 8.2% of
the votes entitled to be cast by holders of shares of Access Health Common Stock
as of the Access Health Record Date.
 
VOTING OF PROXIES
 
    All shares of Access Health Common Stock that are entitled to vote and are
represented at the Access Health Special Meeting either in person or by properly
executed proxies received prior to or at the Access Health Special Meeting and
not duly and timely revoked will be voted at the Access Health Special Meeting
in accordance with the instructions indicated on such proxies. If no such
instructions are indicated, such proxies will be voted for the approval of the
issuance of shares of Access Health Common Stock pursuant to the Merger
Agreement.
 
    If any other matters are properly presented for consideration at the Access
Health Special Meeting including, among other things, consideration of a motion
to adjourn or postpone the Access Health Special Meeting to another time and/or
place (including, without limitation, for the purpose of soliciting additional
proxies), the persons named in the enclosed forms of proxy and voting thereunder
will have the discretion to vote on such matters in accordance with their best
judgment.
 
    Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked by (i) filing
with the Secretary of Access Health at or before the taking of the vote at the
Access Health Special Meeting, a written notice of revocation bearing a later
date than the proxy; (ii) duly executing a later-dated proxy relating to the
same shares and delivering it to the Secretary of Access Health, before the
taking of the vote at the Access Health Special Meeting or (iii) attending the
Access Health Special Meeting and voting in person (although attendance at the
Access Health Special Meeting will not in and of itself constitute a revocation
of a proxy). Any written notice of revocation or subsequent proxy should be sent
so as to be delivered to Access Health, Inc. at 335 Interlocken Parkway,
Broomfield, Colorado 80021, Attention: Secretary, or hand-delivered to the
Secretary of Access Health, in each case at or before the taking of the vote at
the Access Health Special Meeting.
 
SOLICITATION OF PROXIES; EXPENSES
 
    The cost of the solicitation of proxies of Access Health stockholders will
be borne by Access Health. Proxies may be solicited by certain Access Health
directors, officers and employees personally or by telephone, telecopy or other
means of communication. Such persons will not receive additional compensation,
but may be reimbursed for reasonable out-of-pocket expenses incurred in
connection with such solicitation. Following the original mailing of the proxies
and other soliciting materials, Access Health will request that brokers,
custodians, nominees and other record holders forward copies of the proxy and
other soliciting materials to persons for whom they hold shares of Access Health
Common Stock and request authority for the exercise of proxies. In such cases,
Access Health, upon the request of the record holders, will reimburse such
record holders for their reasonable expenses. Access Health has retained
Corporate
 
                                       31
<PAGE>
Investor Communications, Inc. to assist in the solicitation of proxies at a cost
of approximately $20,000, plus customary expenses.
 
           SOLICITATION OF WRITTEN CONSENTS OF INTERQUAL STOCKHOLDERS
 
PURPOSE OF THE INTERQUAL WRITTEN CONSENT
 
    Holders of InterQual Class A Common Stock are being asked to consent in
writing to a proposal to approve and adopt the Merger Agreement, the Merger and
the transactions contemplated thereby, by which InterQual would become a wholly
owned subsidiary of Access Health. The InterQual Board has unanimously approved
the Merger Agreement, the Merger and the transactions contemplated thereby and
recommends that the holders of InterQual Class A Common Stock consent in writing
to the approval and adoption of the Merger Agreement, the Merger and the
transactions contemplated thereby. In addition, this Notice and Consent
Solicitation Statement is being furnished to holders of InterQual Class B Common
Stock, if any, and holders of options to purchase InterQual Class B Common Stock
for notice purposes. Although currently there are no outstanding shares of
InterQual Class B Common Stock, pursuant to the terms of InterQual's 1994
Non-Qualified Stock Option Plan and the stock option agreements between
InterQual and the holders of options to acquire InterQual Class B Common Stock,
the unvested portion of such options will become fully exercisable immediately
prior to the consummation of the Merger. If such options are exercised in
accordance with their terms immediately prior to the consummation of the Merger,
such optionholders will become holders of InterQual Class B Common Stock
immediately prior to the consummation of the Merger and therefore entitled to
all of the rights of stockholders under Delaware law. See "Solicitation of
Written Consents of InterQual Stockholders-- Appraisal Rights" and "Approval of
the Merger and Related Transactions--Delaware Appraisal Rights."
 
RECORD DATE AND OUTSTANDING SHARES
 
    Only stockholders of record of InterQual Class A Common Stock at the close
of business on the InterQual Record Date, which is May 15, 1998, are entitled to
notice of, and to vote by, the InterQual written consent. As of the InterQual
Record Date, there were eight stockholders of record holding an aggregate of
10,000 shares of InterQual Class A Common Stock.
 
VOTE REQUIRED
 
    Approval and adoption of the Merger Agreement, the Merger and the
transactions contemplated thereby require the affirmative vote of the holders of
a majority of the outstanding InterQual Class A Common Stock. Each stockholder
of record of InterQual Class A Common Stock on the InterQual Record Date is
entitled to one vote per share on each matter properly submitted for the vote of
the stockholders of InterQual Class A Common Stock by the InterQual written
consent.
 
    Approval of the Merger Agreement, the Merger and the transactions
contemplated thereby shall constitute approval of the terms of the Escrow
Agreement and the appointment of Charles M. Jacobs as the representative of the
InterQual stockholders under the Escrow Agreement. See "Approval of the Merger
and Related Transactions--Escrow Fund."
 
    Charles M. Jacobs, a holder of InterQual Class A Common Stock has entered
into an Affiliate/Voting Agreement with Access Health, pursuant to which he has
agreed to vote (i) in favor of approval of the Merger Agreement and (ii) against
(among other things) approval of any proposal made in opposition to or in
competition with consummation of the Merger. In addition, Mr. Jacobs has
granted, pursuant to the Affiliate/Voting Agreement, to each director on the
Access Health Board, an irrevocable proxy to vote such shares as aforesaid and
to exercise other rights including the execution and delivery of written
consents with respect to such shares. The shares of InterQual Class A Common
Stock subject to the Affiliate/Voting Agreement represent approximately 50.01%
of the votes entitled to be cast by holders of shares of InterQual Class A
Common Stock. THE VOTE IN ACCORDANCE WITH THE AFFILIATE/
 
                                       32
<PAGE>
VOTING AGREEMENT OF THE SHARES OF INTERQUAL CLASS A COMMON STOCK SUBJECT TO THE
AFFILIATE/VOTING AGREEMENT WILL BE SUFFICIENT TO APPROVE AND ADOPT THE MERGER
AGREEMENT.
 
WRITTEN CONSENT SOLICITATION; EXPENSES
 
    InterQual stockholders are requested to complete, sign, date and return
prior to June 30, 1998 the enclosed InterQual written consent in the
postage-prepaid envelope provided for the purpose of voting "FOR" approval of
the Merger Agreement. Failure to return the InterQual written consent will have
the practical effect of voting against the approval of the Merger Agreement.
 
    The cost of the solicitation of the written consents of the InterQual Class
A Common Stockholders will be borne by InterQual. Consents may be solicited by
certain InterQual directors, officers and employees personally or by telephone,
telecopy or other means of communication. Such persons will not receive
additional compensation, but may be reimbursed for reasonable out-of-pocket
expenses incurred in connection with such solicitation.
 
APPRAISAL RIGHTS
 
    Holders of InterQual Class A Common Stock who do not vote by written consent
in favor of the Merger and holders of InterQual Class B Common Stock may, under
certain circumstances and by following procedures prescribed by Section 262 of
the DGCL, exercise appraisal rights and receive cash for their shares of
InterQual Capital Stock. A dissenting stockholder of InterQual must follow the
appropriate procedures under Delaware law or suffer the termination or waiver of
such rights. See "Approval of the Merger and Related Transactions--Delaware
Appraisal Rights."
 
                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
    THE FOLLOWING DISCUSSION SUMMARIZES THE PROPOSED MERGER AND RELATED
TRANSACTIONS. THE FOLLOWING IS NOT, HOWEVER, A COMPLETE STATEMENT OF ALL
PROVISIONS OF THE MERGER AGREEMENT AND RELATED AGREEMENTS. DETAILED TERMS OF AND
CONDITIONS TO THE MERGER AND CERTAIN RELATED TRANSACTIONS ARE CONTAINED IN THE
MERGER AGREEMENT, A CONFORMED COPY OF WHICH IS ATTACHED TO THIS PROXY
STATEMENT/PROSPECTUS AND NOTICE AND CONSENT SOLICITATION STATEMENT AS ANNEX A.
STATEMENTS MADE IN THIS PROXY STATEMENT/PROSPECTUS AND NOTICE AND CONSENT
SOLICITATION STATEMENT WITH RESPECT TO THE TERMS OF THE MERGER AND SUCH RELATED
TRANSACTIONS ARE QUALIFIED IN THEIR RESPECTIVE ENTIRETIES BY REFERENCE TO, AND
HOLDERS OF ACCESS HEALTH COMMON STOCK AND INTERQUAL CAPITAL STOCK ARE URGED TO
READ, THE MORE DETAILED INFORMATION SET FORTH IN THE MERGER AGREEMENT AND THE
OTHER DOCUMENTS ANNEXED HERETO.
 
ACCESS HEALTH'S REASONS FOR THE MERGER
 
    The Access Health Board has unanimously approved and ratified the Merger
Agreement and the Merger, has determined that the terms of the Merger Agreement
are fair to, and that the Merger is in the best interests of, Access Health and
its stockholders and therefore unanimously recommends that the holders of Access
Health Common Stock vote in favor of approval of the issuance of Access Health
Common Stock pursuant to the Merger Agreement.
 
    In reaching its determination to approve the Merger Agreement and the
transactions contemplated thereby, the Access Health Board has identified the
following potential benefits* of the Merger that it believes may contribute to
the success of the combined company:
 
    - STRENGTHEN POSITION AS A LEADING CARE MANAGEMENT COMPANY. The Merger
      represents a complementary combination of two leading companies in the
      development and delivery of care management services and clinical criteria
      which improve the quality and reduce the cost of health care services.
      Access Health is the industry leader in developing care management
      services that are used to guide individuals with health care conditions to
      the appropriate point of care and to assist them in
 
                                       33
<PAGE>
      managing chronic conditions. InterQual's products represent an industry
      standard to support clinical decision making by physicians. Access Health
      intends to integrate InterQual's Criteria into a care management service
      offering to support providers in making appropriate health care decisions
      for their patients.* Access Health believes that the new services will
      extend Access Health's care management capabilities beyond its patient
      focused triage and disease management services and will enable the Company
      to increase its ability to positively impact health care costs and
      quality.*
 
    - EXPANDED CUSTOMER BASE. InterQual has approximately 1,700 customers,
      including 500 licensed health plans and health care insurers and 1,200
      hospital organizations. Access Health believes there is a significant
      opportunity to provide additional care management services to existing
      InterQual customers and to promote InterQual Criteria and services based
      on InterQual Criteria to existing Access Health customers.*
 
    - OPPORTUNITY TO REDUCE DUPLICATIVE INVESTMENTS AND PURSUE NEW PRODUCTS AND
      SERVICES. The combined company is expected to have a more focused and
      coordinated research and development program that should reduce aggregate
      investment requirements and provide the opportunity for the combined
      company to pursue new product and service opportunities.*
 
    - EXPAND MANAGEMENT RESOURCES. The integrated management team is expected to
      possess expanded expertise to manage the development of each of the
      combined companies' growing segments with particular emphasis on managed
      care, health plans, physician groups, hospital organizations, and
      international sectors.*
 
    - OPPORTUNITY TO REALIZE OPERATING SYNERGIES. Access Health and InterQual
      will jointly develop an integration plan that will identify potential cost
      savings as a result of the transaction, which savings are expected to
      improve operating results of the combined company over time.*
 
    - PROJECTED LONG-TERM OPERATING RESULTS ACCRETION. Combined company
      operating results are expected to become accretive but not until fiscal
      1999.*
 
    In the course of its deliberations, the Access Health Board reviewed and
considered a number of other factors relevant to the Merger. In particular, the
Access Health Board considered, among other things, the following factors:
 
    (i) Information concerning Access Health's and InterQual's respective
businesses, financial position, results of operations, product development
schedules, technologies and properties;
 
    (ii) The reports of Access Health's management including reports relating to
the extensive due diligence review which had been conducted regarding
InterQual's business, operations, technology and competitive position, and
possible synergistic and expansion opportunities for the two companies;
 
   (iii) The multiples of comparable publicly traded companies in the industry,
the discounted future cash flows of InterQual based on management's projections
and an analysis of the respective contributions to revenues, operating profits
and net profits of the combined companies based on managements' projections;
 
    (iv) The oral opinion of BancAmerica Robertson Stephens dated June 1, 1998
delivered to the Access Health Board on June 2, 1998, that as of June 1, 1998,
and based upon the assumptions made, matters considered and limits of review set
forth therein, the Merger Consideration was fair, from a financial point of
view, to Access Health;
 
    (v) The expectation that the Merger will qualify for pooling-of-interests
treatment for financial reporting purposes and will be tax-free for federal
income tax purposes to Access Health;
 
    (vi) A review with Access Health's legal counsel of the terms of the Merger
Agreement, including the obligation of InterQual not to solicit or encourage
other acquisition proposals, the breakup fee provisions, the circumstances under
which either Access Health or InterQual can terminate the Merger Agreement and
the closing conditions to the Merger;
 
                                       34
<PAGE>
   (vii) The compatibility of the corporate cultures of Access Health and
InterQual which the Access Health Board believed was important for the
successful integration of the companies; and
 
  (viii) The fact that the issuance of Access Health Common Stock pursuant to
the Merger Agreement is conditioned upon approval by a majority of the votes
cast at the Access Health Special Meeting and that the Merger is conditioned
upon approval of the Merger Agreement by the holders of a majority of the
outstanding shares of InterQual Class A Common Stock.
 
    The Access Health Board also considered a variety of potentially negative
factors in its deliberations concerning the Merger. While the totality of all
applicable risks were considered, the Access Health Board placed emphasis on
certain negative factors including (i) the initial dilutive effect of the
issuance of Access Health Common Stock in the Merger*, including the risk that
present revenue growth rates may decline, which is discussed in more detail in
"Risk Factors--Risks Related to the Merger--Potential Dilutive Effect to
Stockholders"; (ii) the risk that earnings per share accretion may not
materialize as quickly as anticipated, which is discussed in more detail in
"Risk Factors--Risks Related to the Merger--Potential Dilutive Effect to
Stockholders"; (iii) the material nature of the charges expected to be incurred,
primarily in the quarter ended June 30, 1998, in connection with the Merger,
including the transaction expenses arising from the Merger, which is discussed
in more detail in "Risk Factors--Risks Related to the Merger--Material Expenses
Resulting from the Merger Will Impact Results of Operations"; and (iv) the risk
that, despite the intentions and efforts of the parties, Access Health may not
be able to retain the key technical and management personnel of InterQual. In
addition to the preceding risks, the Board considered all other material risks
including (i) the risk that, despite the intentions and the efforts of the
parties, the benefits sought to be achieved in the Merger may not be achieved;
(ii) the risk that the market price of Access Health Common Stock might be
adversely affected by the public announcement of the Merger; and (iii) all other
risks described above under "Risk Factors."
 
    The foregoing discussion of the information and factors considered by the
Access Health Board is not intended to be exhaustive but is believed to include
all material factors considered by the Access Health Board. In view of the
variety of factors considered in connection with its evaluation of the Merger,
the Access Health Board did not find it practicable to and did not quantify or
otherwise assign relative weights to the specific factors considered in reaching
its determination, nor in the course of its deliberations, did the Access Health
Board establish a range of values for InterQual. In addition, individual members
of the Access Health Board may have given different weights to different
factors. While Access Health management undertook significant effort to evaluate
InterQual as a potential strategic acquisition based on an analysis of the two
companies' operating structures, products, marketing strategies and customers,
they were not able to quantify specific benefits precisely. Access Health does,
however, estimate that potential operating results may be accretive subsequent
to the Merger.* Access Health believes such accretive benefits could be achieved
based on the present level of earnings and revenue growth of InterQual and the
combined abilities of the two companies.* Finally, while the Access Health Board
did not consider any particular factors to be disproportionately significant,
certain factors were given emphasis. First, Access Health believes that the
combination presents the potential to broaden Access Health's capabilities to
provide a full range of care management products and services and strengthen its
position as a leading provider of such products and services.* Second, the
potential expanded customer base of the combined companies may present a
significant cross-marketing opportunity for both Access Health and InterQual.*
Notwithstanding the enhanced significance of the preceding factors, the Access
Health Board's ultimate determination was based on the consideration of the
totality of positive factors weighed against the negative factors. The Access
Health Board concluded that on balance, the positive factors outnumber and
outweigh the negative factors.* In reaching such determination through the
exercise of its business judgment, the Access Health Board determined that the
proposed transaction will provide the greatest benefit to Access Health and its
stockholders.

INTERQUAL'S REASONS FOR THE MERGER
 
    The InterQual Board has approved the Merger Agreement and the Merger, has
determined that the terms of the Merger Agreement are fair to, and that the
Merger is in the best interests of, InterQual and its stockholders and therefore
recommends that the holders of InterQual Class A Common Stock vote in favor of
approval of the Merger Agreement.
 
    The InterQual Board believes the Merger will be beneficial for the following
principal reasons:
 
    - EXPANDED RESOURCES; LEVERAGE TECHNICAL CAPABILITIES; ENHANCED COMPETITIVE
      POSITION. The Merger is expected to provide InterQual with greater
      financial, technical, sales and marketing and other operational resources
      to facilitate its continued rapid growth.* In addition, the combined
      development efforts of the companies are expected to enhance the breadth
      and productivity and reduce the cost of product and system development and
      enhance its competitive position.*
 
    - OPERATIONAL EFFICIENCIES. The companies should be able to reduce some
      duplicative overhead costs and investments and develop an integration plan
      that will identify potential cost savings and help the combined companies
      to coordinate their efforts in developing new products and services to
      their combined customer bases.* While InterQual is not able to quantify
      the potential reduction in expenses precisely, Interqual expects such
      savings to result from efficiencies which should allow the combined
      companies to compete more effectively.* These efficiencies are expected to
      result from the: (i) expanded technical and information systems,* (ii)
      increased research and development, sales, marketing and account
      management resources and expertise,* and (iii) greater financial capacity,
      of the combined companies.*
 
    - EXPANDED CUSTOMER BASE. The Merger is expected to enable InterQual to
      leverage Access Health's customer relationships in the health plan and
      provider markets to help the combined company achieve a leading market
      position in its target customer groups.*
 
    - COMPLEMENTARY PRODUCT LINES. The Merger is expected to bring together two
      complementary product lines which should allow the combined companies to
      address a broader market and to provide their customers with a more
      complete product solution.*
 
    - PUBLICLY TRADED STOCK. InterQual stockholders will receive Access Health
      Common Stock in the Merger, which is a publicly traded stock on Nasdaq, in
      contrast to the illiquid nature of their present holdings of InterQual
      stock.
 
    In reaching its conclusions to approve the Merger, the InterQual Board
considered, among other things, the following factors:
 
    (i) Access Health's and InterQual's respective businesses, financial
position, historical and prospective results of operations, market position,
product development plans and technical capabilities;
 
    (ii) InterQual's other potential strategic and financial options, including
acquisition and partnership proposals which had been received from other
companies and the pursuit of an initial public offering as an independent
company at some later date;
 
   (iii) Reports of InterQual's management and financial, legal and accounting
advisors, including reports relating to the due diligence review which had been
conducted regarding Access Health's business, operations, technology and
competitive position and possible synergistic and expansion opportunities for
the two companies;
 
    (iv) With the assistance of its financial advisors, the value of the
consideration to be exchanged by Access Health for the InterQual Capital Stock
relative to: (a) the respective contribution of Access Health and InterQual to
the revenue, operating income and net income of the combined companies, based on
consensus estimates of Access Health's future results from securities industry
analysts; (b) the valuation multiples of selected comparable publicly traded
companies; and (c) the implied valuation multiples in comparable merger
transactions.
 
                                       36
<PAGE>
    (v) The oral opinion of Volpe Brown Whelan delivered on June 1, 1998
confirming its written opinion dated May 29, 1998 to the effect that as of such
date, that the Exchange Ratio was fair, from a financial point of view, to
InterQual;
 
    (vi) Information on historical price and volume trading data for Access
Health's Common Stock as well as the composition of Access Health's stockholder
base;
 
   (vii) The expectation that the Merger will qualify for pooling-of-interests
treatment for financial reporting purposes and will constitute a tax-free
reorganization for federal income tax purposes to InterQual's stockholders;
 
  (viii) A review with InterQual's legal counsel of the terms of the Merger
Agreement, including the Affiliate/Voting and Affiliate Agreements, Employee
Agreements, Registration Rights Agreement, the obligation of InterQual not to
solicit or encourage other acquisition proposals, the representations and
warranties of InterQual and Access Health, the break-up fee provisions, the
share escrow and indemnification provisions, the circumstances under which
either InterQual or Access Health can terminate the Merger Agreement and the
closing conditions to the Merger (including stockholder approval requirements);
 
    (ix) The fact that a designee of InterQual would be appointed to the Access
Health Board. See "InterQual--Management."
 
    The InterQual Board also considered a variety of potentially negative
factors in its deliberations concerning the Merger, including: (i) the risk
that, despite the intentions and efforts of the parties, the operational and
competitive benefits sought to be achieved in the Merger will not be achieved;
(ii) the risk that the market value and liquidity of Access Health Common Stock
might be adversely affected; (iii) the risk that existing or prospective
customers may not respond positively to the Merger announcement; (iv) the risk
that despite the intentions and efforts of the parties, the key technical and
management personnel of InterQual and Access Health required to facilitate a
successful integration may not remain with the combined company; (v) the risk of
the loss of key Access Health customers or other negative impacts on Access
Health's business; and (vi) the other risks described above under "Risk
Factors." Despite these potentially negative factors and other risks described
above under "Risk Factors," the InterQual Board believes that the risk of not
securing the benefits which the InterQual Board believes will result from the
Merger outweigh the potentially negative factors and risks related to the
consummation of the Merger.*
 
    The foregoing discussion of the information and factors considered by the
InterQual Board is not intended to be exhaustive but is believed to include all
material factors considered by the InterQual Board. In view of the variety of
factors considered in connection with its evaluation of the Merger, the
InterQual Board did not find it practicable to and did not quantify or otherwise
assign relative weights to the specific factors considered in reaching its
determination; rather it was on the basis of the totality of the positive
factors, which in the opinion of the InterQual Board outnumbered and outweighed
the negative factors, upon which the InterQual Board exercising its business
judgment based its decision that the contemplated transaction will provide the
greatest benefits to InterQual and its stockholders. In addition, individual
members of the InterQual Board may have given different weights to different
factors.

                                       37
<PAGE>
UNANIMOUSLY RECOMMENDS THAT HOLDERS OF INTERQUAL CLASS A COMMON STOCK PROVIDE
WRITTEN CONSENT FOR THE MERGER AGREEMENT.
 
BACKGROUND OF THE MERGER
 
    On a number of occasions in 1996 and early 1997, members of Access Health's
clinical staff and members of InterQual's clinical staff met in the ordinary
course of business and discussed ways in which Access Health and InterQual could
work together.
 
    On February 3, 1997, the InterQual Board met at a regularly scheduled board
meeting and considered the strategic options which were currently available to
InterQual, including a number of informal strategic partnerships and financial
restructuring opportunities and the possibility of a public offering. The
InterQual Board determined to engage a financial adviser to advise it on its
strategic options.
 
    On April 16, 1997, Joseph P. Tallman, currently the Chief Executive Officer
of Access Health in his capacity as the President and Chief Operating Officer of
the Company, and Timothy H. Connor, Chief Financial Officer of Access Health,
met Charles M. Jacobs, Chief Executive Officer of InterQual, and Henry F.
Nelson, Jr., Chief Operating Officer of InterQual, at a trade conference, and
discussed a more in-depth working relationship between the two companies,
including the possibility of licensing InterQual Criteria for use in a
utilization management outsource service.
 
    On April 30, 1997, InterQual selected Volpe Brown Whelan as its financial
adviser. Volpe Brown Whelan's advice in favor of a merger strategy was accepted.
Thereupon, Volpe Brown Whelan prepared an information memorandum and initiated a
two stage auction process commencing in August of 1997. Volpe Brown Whelan and
InterQual initially evaluated an extensive list of potentially interested
parties in related areas of activity and with the necessary financial capacity
to undertake a possible combination transaction. Volpe Brown Whelan then
contacted on a confidential basis and sent information memoranda to 17
potentially interested parties to solicit their interest in a combination
transaction with InterQual.
 
    On August 27, 1997, Messrs. Tallman and Connor of Access Health and Messrs.
Jacobs and Nelson of InterQual met to further discuss the licensing arrangements
and to discuss potential, synergistic relationships.
 
    On September 23, 1997, Volpe Brown Whelan contacted Access Health and
inquired of its interest in pursuing a combination transaction with InterQual.
Volpe Brown Whelan and Access Health negotiated and prepared a confidentiality
agreement which was executed on October 1, 1997. On October 1, 1997 Volpe Brown
Whelan sent letters to the 17 parties including Access Health who had been
contacted in relation to a combination transaction with InterQual. The letter
requested the 17 parties to provide proposed terms of a combination transaction
to be submitted no later than October 21, 1997.
 
    On October 21, 1997 Volpe Brown Whelan received five proposals for a
combination transaction with InterQual. These replies included a letter from Mr.
Tallman of Access Health, who expressed Access Health's interest in pursuing a
combination transaction with InterQual and proposed a stock-for-stock merger to
be accounted for as a pooling of interests. The letter was subject to a number
of contingencies including a due diligence review of InterQual, Access Health
Board and stockholder approval and the agreement of certain key members of
InterQual's management team to enter into employment agreements and/or
non-competition agreements.
 
    On October 24, 1997, Volpe Brown Whelan met with the InterQual Board in a
telephonic meeting and presented a review of the five proposals which had been
received from interested parties. The InterQual Board reviewed each of the
proposals on the basis of the value of consideration proposed, the form of
consideration, the proposed terms of the transaction, the expected time frame to
completion and any contingent liabilities which would reside with InterQual
shareholders. On the basis of this review, the InterQual Board determined to
invite four interested parties to meet certain management of InterQual and
perform due diligence.
 
                                       38
<PAGE>
    On November 11 and 12, 1997, representatives of Access Health, including Mr.
Tallman, Mr. Connor, Michael Myers, Senior Vice President of Marketing and
Technology, and Julie A. Brooks, Senior Vice President and General Counsel, met
with members of InterQual's management team, including Mr. Jacobs, Josephine A.
Lamprey, President, Susan Weagly Jacobs, Senior Vice President, Mr. Nelson, and
other InterQual officers, and with representatives of Volpe Brown Whelan to
discuss InterQual's business, operations, products and financial prospects. In
addition, the potential structure and the potential benefits of a combination of
InterQual with Access Health were discussed. Also on November 12, 1997, Access
Health concluded a license on behalf of one of its health plan customers with
InterQual for use of InterQual's Criteria products in certain utilization
management initiatives for such customer.
 
    On December 4, 1997, Volpe Brown Whelan wrote letters to the four interested
parties, including Access Health, inviting the submission of a final proposal
for the acquisition of InterQual. The letters indicated that, based on such
final proposals, InterQual intended to select a single party with whom to offer
the opportunity to conduct exclusive negotiations. The letter further requested
that all final proposals be submitted to Volpe Brown Whelan on or before
December 15, 1997.
 
    On December 10, 1997, Mr. Jacobs, Ms. Lamprey, Ms. Jacobs and Mr. Nelson,
with representatives of Volpe Brown Whelan, met Mr. Tallman, Mr. Connor and
Patrick Benner, Access Health's Director of Corporate Development, at Access
Health's corporate head office in Broomfield, Colorado to discuss Access
Health's business, operations, products and financial prospects. Mr. Tallman
described the potential benefits of a merger and the role InterQual would play
in the combined entity.
 
    On December 12, 1997, the Access Health Board, met and discussed the
potential merger of InterQual with Access Health. The Access Health Board
authorized management to pursue the possibility of a merger with InterQual.
 
    On December 15, 1997, Volpe Brown Whelan received final proposals from the
four interested parties including a letter from Mr. Tallman of Access Health who
proposed detailed terms for a merger of InterQual with Access Health. Mr.
Tallman proposed that Access Health would issue 4,250,000 registered shares of
common stock and options to purchase common stock for all of the outstanding
shares and options of InterQual. The proposal was subject to certain conditions,
including the execution of a definitive agreement, completion of a due diligence
review, receipt of an opinion from Access Health's accountants that the merger
would be treated as a pooling of interests, receipt of an opinion from Access
Health's legal advisers that the merger would be treated as a reorganization
within the meaning of Section 368(a) of the Code and receipt of an opinion from
Access Health's financial advisers that the Merger Consideration was fair from a
financial point of view to Access Health.
 
    On December 21 and 22, 1997, Volpe Brown Whelan met with the InterQual Board
and presented a review of the final proposals which had been received from the
four interested parties. The InterQual Board reviewed each of the final
proposals on the basis of value of the consideration proposed, the form of the
consideration, the proposed terms of the combination transaction and any
contingent liabilities which would reside with InterQual shareholders. The
InterQual Board then authorized Volpe Brown Whelan to return to certain parties
that had submitted final proposals to discuss their willingness to modify the
terms of their bid. Between December 23 and December 26, Volpe Brown Whelan had
several discussions with Access Health and other interested parties. On the
basis of such discussions the Access Health proposal was determined to be the
most attractive and on January 7, 1997, Access Health and InterQual executed an
exclusivity agreement to negotiate a definitive agreement for the merger of
InterQual with Access Health.
 
    On January 14 and 15, 1998, representatives of Access Health, its legal
adviser, Wilson Sonsini Goodrich & Rosati, its independent public accountants,
Arthur Andersen LLP, and its financial adviser, BancAmerica Robertson Stephens,
met with representatives of InterQual and Volpe Brown Whelan in Marlborough,
Massachusetts to conduct financial and legal due diligence regarding InterQual.
 
                                       39
<PAGE>
    On January 16, 1998, representatives of Ropes & Gray, InterQual's legal
adviser in connection with the proposed Access Health transaction, and a
representative of Volpe Brown Whelan met with representatives of Access Health
in Broomfield, Colorado to conduct financial and legal due diligence regarding
Access Health.
 
    On January 26, 1998, Mr. Jacobs and Douglas L. Elden of The Elden Law Firm,
InterQual's corporate counsel, met with Mr. Tallman and Kinney L. Johnson, a
member of the Access Health board, in Broomfield, Colorado, and on January 27,
1998 met with Richard C. Miller and Frank G. Washington, a member and Chairman
of Access Health's board, respectively, in Sacramento, California to discuss the
role InterQual would have in the combined entity and InterQual's representation
on the Access Health Board.
 
    From January 14, 1998 to February 13, 1998, legal counsel for Access Health
and InterQual negotiated the terms of and prepared the definitive merger
agreement and related agreements and documents. Representatives of Access Health
and InterQual and their respective financial advisers participated in these
negotiations by telephone and in person on occasion during this period.
 
    From January 19 through January 21, 1998, Price Waterhouse, InterQual's
accounting consultants conducted accounting due diligence regarding Access
Health at the Sacramento, California offices of Ernst & Young, Access Health's
former independent public accountants, and at Access Health's offices in
Broomfield, Colorado.
 
    On January 20, 1998, the Access Health Board held a special telephonic
meeting during which management and legal counsel reviewed the results of their
due diligence of InterQual, management reviewed the possible benefits and risks
relating to the proposed merger, the directors reviewed with management and
legal counsel the specific terms of the proposed merger agreement and
BancAmerica Robertson Stephens discussed certain of its preliminary analyses
with the Access Health Board.
 
    On February 9, 1998, InterQual's directors, by unanimous consent, approved
the Merger Agreement. By this consent, the directors also authorized Mr. Jacobs,
InterQual's Chief Executive Officer to execute and deliver the Merger Agreement
substantially in the same form and content furnished to them with such
modifications as approved by him in his sole discretion, and declared that such
execution and delivery was to be conclusive evidence that the Merger Agreement
was authorized by the directors of InterQual.
 
    On February 10, 1998, the Access Health Board held a special telephonic
meeting, reviewed the proposed final Merger Agreement and related documents and
discussed preliminary valuation results with BancAmerica Robertson Stephens. The
Access Health Board authorized the Access Health management to complete
negotiation of the Merger Agreement subject to final approval of the Access
Health Board.
 
    On February 13, 1998 the Access Health Board held a special telephonic
meeting during which it reviewed the final terms of the Merger Agreement and
related documents and reviewed the oral opinion of BancAmerica Robertson
Stephens, subsequently confirmed in writing as of such date, that, as of
February 13, 1998, and based upon the assumptions made, matters considered and
limits of review set forth therein, the Merger Consideration was fair, from a
financial point of view, to Access Health. After deliberations, a majority of
the Access Health Board approved the Merger and the Merger Agreement. Access
Health and InterQual then executed the Merger Agreement that day, and at 7:00
a.m. EST on February 17, 1998 Access Health announced that it had executed the
Merger Agreement.
 
    On March 4, 1998, the Access Health Board held a special telephone meeting
during which it unanimously ratified the Merger and the Merger Agreement.
 
    On May 19, 1998 Messrs. Tallman and Connor of Access Health called Mr.
Jacobs and a representative of Volpe Brown Whelan and proposed revising the
terms of the Merger Agreement. Over the following week, Mr. Tallman and Mr.
Jacobs had discussions about revising the terms of the Merger Agreement. On May
29, 1998 Messrs. Tallman and Connor called Mr. Jacobs and the parties agreed to
amend the Merger Agreement to limit the maximum number of Access Health shares
to be issued to 4,540,000 for all of the outstanding shares and options of
InterQual.

    On June 1, 1998, the InterQual Board held a special meeting during which it
reviewed the terms of the amendments to be entered into to the Merger Agreement
and reviewed the opinion of Volpe Brown Whelan dated as of May 29, 1998
confirming that as of such date the Exchange Ratio was fair from a financial
point of view to InterQual.
 
    On June 2, 1998 the Access Health Board held a special telephonic meeting
during which it reviewed the terms of the amendments to be entered into to the
Merger Agreement and reviewed the opinion of BancAmerica Robertson Stephens
dated as of June 1, 1998 confirming that as of such date, based upon the
assumptions made, matters considered and limits of review set forth therein, the
Merger Consideration as reviewed was fair, from a financial point of view, to
Access Health.
 
OPINION OF ACCESS HEALTH'S FINANCIAL ADVISOR
 
    On December 29, 1997, Access Health and BancAmerica Robertson Stephens
executed an engagement letter (the "Engagement Letter") pursuant to which
BancAmerica Robertson Stephens was engaged to render an opinion as to the
fairness of the Merger Consideration, from a financial point of view, to Access
Health. See "Approval of the Merger and Related Transactions--Background of the
Merger."
 
   
    On February 13, 1998, at a meeting of the Access Health Board held to
evaluate the proposed Merger, BancAmerica Robertson Stephens delivered to the
Access Health Board its oral opinion, subsequently confirmed in writing as of
such date, that as of February 13, 1998, and based on the assumptions made,
matters considered and limits of review set forth therein, the Merger
Consideration was fair, from a financial point of view, to Access Health. On
June 2, 1998, BancAmerica Robertson Stephens delivered to the Access Health
Board its written opinion dated June 1, 1998 (the "BancAmerica Robertson
Stephens Opinion") that, based on the assumptions made, matters considered and
limits of review set forth therein, the Merger Consideration was fair, from a
financial point of view, to Access Health. The BancAmerica Robertson Stephens
Opinion dated as of June 1, 1998, is substantially similar to the opinion dated
February 13, 1998. No limitations were imposed by the Access Health Board on
BancAmerica Robertson Stephens with respect to the investigations made or
procedures followed by it in furnishing its opinion. The Merger Consideration
was determined through negotiations between the managements of Access Health and
InterQual. BancAmerica Robertson Stephens did not recommend to the Access Health
Board that any specific exchange ratio should constitute the Merger
Consideration. In furnishing its opinion, BancAmerica Robertson Stephens was not
engaged as an agent or fiduciary of Access Health's stockholders or any other
person. BancAmerica Robertson Stephens has consented to the inclusion and use of
its opinion in this Proxy Statement/Prospectus and Notice and Consent
Solicitation Statement, and the discussion herein regarding such opinion is
acceptable to BancAmerica Robertson Stephens.
    
 
    THE FULL TEXT OF THE BANCAMERICA ROBERTSON STEPHENS OPINION, WHICH SETS

THIS PROXY STATEMENT/PROSPECTUS AND NOTICE AND CONSENT SOLICITATION STATEMENT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE BANCAMERICA
ROBERTSON STEPHENS OPINION.
 
    In connection with the preparation of the BancAmerica Robertson Stephens
Opinion, BancAmerica Robertson Stephens, among other things, (i) reviewed
certain financial information furnished to it by Access Health, including
certain internal financial analyses and forecasts by the management of
InterQual; (ii) reviewed publicly available information concerning Access
Health; (iii) held discussions with the managements of each of Access Health and
InterQual concerning the businesses, past and current business operations,
financial condition, results of operations and future prospects of each company,
independently and combined; (iv) reviewed the terms of a draft of the Merger
Agreement; (v) reviewed the stock price and trading history of Access Health
Common Stock; (vi) reviewed the contribution by each company to pro forma
combined revenue, operating income and net income of the proposed combined
company; (vii) reviewed the valuations of publicly traded companies which were
deemed comparable to InterQual; (viii) compared the financial terms of the
Merger set forth in the Merger Agreement with other transactions which
BancAmerica Robertson Stephens deemed relevant; (ix) analyzed the pro forma
earnings per share of the combined company; and (x) made such other studies and
inquiries, and reviewed such other data, as it deemed relevant.
 
    In connection with arriving at its opinion, BancAmerica Robertson Stephens
assumed and relied upon, without independent verification, the accuracy and
completeness of all information reviewed by it in connection with its engagement
by Access Health with respect to the Merger and has relied upon the assurances
of management of each of Access Health and InterQual that they are not aware of
any facts that would make such information inaccurate or misleading.
Furthermore, BancAmerica Robertson Stephens did not obtain any independent
evaluation or appraisal of any of the properties, assets or liabilities
(contingent or otherwise) of Access Health or InterQual, nor was BancAmerica
Robertson Stephens furnished with any such evaluation or appraisal. With respect
to the financial forecasts and projections (and the assumptions and bases
therefor) of each of Access Health and InterQual which BancAmerica Robertson
Stephens has reviewed, BancAmerica Robertson Stephens has assumed that such
forecasts and projections have been reasonably prepared in good faith on the
basis of reasonable assumptions and reflect the best available estimates and
judgments, as of June 1, 1998, of the managements of Access Health and
InterQual, respectively, as to the future financial performance of each of
Access Health and InterQual, respectively, and BancAmerica Robertson Stephens
has further assumed that such forecasts and projections will be realized in the
amounts and in the time periods estimated by the respective managements of each
of Access Health and InterQual. Further, BancAmerica Robertson Stephens has
assumed that the historical financial statements of each of Access Health and
InterQual reviewed by BancAmerica Robertson Stephens have been prepared and
fairly presented in accordance with U.S. GAAP. BancAmerica Robertson Stephens
has assumed that the Merger will be consummated upon the terms set forth in a
draft of the Merger Agreement without material alteration thereof and that the
Merger will qualify as a tax-free reorganization within the meaning of Section
368(a) of the Code, and be accounted for as a pooling of interests in accordance
with U.S. GAAP. BancAmerica Robertson Stephens relied as to all legal matters
relevant to rendering its opinion on the advice of counsel.
 
    The BancAmerica Robertson Stephens Opinion was necessarily based on market,
economic and other conditions as in effect on, and information made available to
BancAmerica Robertson Stephens as of, June 1, 1998. It should be understood that
subsequent developments may affect the conclusion expressed in the BancAmerica
Robertson Stephens Opinion and that BancAmerica Robertson Stephens disclaims any
undertaking or obligation to advise any person of any change in any fact or
matter affecting the
 
                                       42

opinion which may come or be brought to its attention after the date of the
BancAmerica Robertson Stephens Opinion.
 
    SUMMARY OF ANALYSES.  The following is a summary of the material financial
analyses performed by BancAmerica Robertson Stephens in connection with
rendering the BancAmerica Robertson Stephens Opinion:
 
    COMPARABLE COMPANY ANALYSIS.  Using publicly available information,
BancAmerica Robertson Stephens analyzed, among other things, the market values
plus net debt (the "Total Capitalization") and trading multiples of selected
publicly traded companies in the data analysis/decision support and clinical/
financial applications industry, including: HCIA, Health Risk Management,
Medirisk, Summit Medical Systems and Transitions Systems (the "Data
Analysis/Decision Support Companies"); IDX Systems Corporation and Medical
Manager Corporation (the "Physician Focused Clinical/Financial Application
Companies"); and Cerner Corporation, HBO & Company, Oacis Healthcare, Shared
Medical Systems, and Sunquest Information Systems (the "Hospital Focused
Clinical/Financial Application Companies" and, together with the Data
Analysis/Decision Support Companies and the Physician Focused Clinical/
Financial Application Companies, the "Comparable Companies"). BancAmerica
Robertson Stephens compared the market values of such Comparable Companies as
multiples of, among other things, estimated calendar 1998 and 1999 net income.
The aggregate market values of the Data Analysis/Decision Support Companies
ranged from 15.0x to 30.0x 1998 net income estimates and 15.0x to 21.1x 1999 net
income estimates, with an average aggregate market value of 23.9x 1998 net
income estimates and 18.9x 1999 net income estimates. The aggregate market
values of the Physician Focused Clinical/Financial Application Companies ranged
from 33.9x to 34.8x 1998 net income estimates and 25.2x to 27.9x 1999 net income
estimates, with an average aggregate market value of 34.3x 1998 net income
estimates and 26.5x 1999 net income estimates. The aggregate market values of
the Hospital Focused Clinical/Financial Application Companies ranged from 18.0x
to 43.1x 1998 net income estimates and 14.4x to 33.4x 1999 net income estimates,
with an average aggregate market value of 31.1x 1998 net income estimates and
22.8x 1999 net income estimates. All multiples were based on closing stock
prices as of May 29, 1998. Based on this information and other publicly
available information, BancAmerica Robertson Stephens applied a range of
multiples of 25x to 30x and 18x to 23x, respectively, to InterQual's estimated
1998 and 1999 net income resulting in an equity reference range for InterQual of
approximately $96 to $208 million without giving effect to a control premium and
approximately $120 to $291 after giving effect to a 25-40% control premium, as
compared to the equity value implied by the Merger Consideration of
approximately $110 million based on the closing price of Access Health Common
Stock on May 29, 1998 and the average closing price of Access Health Common
Stock over the 20 consecutive trading days ending May 29, 1998.
 
    PRECEDENT TRANSACTION ANALYSIS.  Using publicly available information,
BancAmerica Robertson Stephens analyzed the consideration offered plus net debt
assumed (the "Total Consideration") and implied transaction value multiples paid
or proposed to be paid in selected transactions in the health care systems and
services industry, including: United HealthCare/MediCode (December 7, 1997),
QuadraMed Corporation/Medicus Systems Corporation (November 11, 1997), HBO &
Company/National Health Enhancements Systems (October 3, 1997), HBO &
Company/HPR, Inc. (September 29, 1997), IDX Systems/ Phamis, Inc. (March 25,
1997), HBO & Company/Enterprise Systems (March 14, 1997), HBO & Company/ AMISYS
Managed Care (February 11, 1997), and HBO & Company/GMIS (September 24, 1996)
(collectively, the "Precedent Transactions"). BancAmerica Robertson Stephens
compared, among other things, the total consideration in such transaction as a
multiple of forecasted revenues for the twelve month period subsequent ("NTM")
to the announcement of the respective acquisitions and also compared the equity
consideration in such transactions as a multiple of the preceding twelve months
("LTM") and NTM net income. The Precedent Transactions illustrated a range of
Total Consideration equal to 1.5x to 6.3x NTM revenues, with an average multiple
of 3.4x and a range of equity consideration equal to 25.5x to 34.5x NTM net
income, with an average of 30.4x NTM net income. Based on this information and
other publicly available information, BancAmerica Robertson Stephens applied a
range of multiples for the Precedent Transactions of forecasted 1998 revenues of
3.0x to 5.0x and 1998 net income of 27x to 33x, respectively to
 
                                       43
<PAGE>
corresponding financial data for InterQual, indicating implied acquisition
valuations for InterQual from approximately $86-$188 million, as compared to the
equity value implied by the Merger Consideration of approximately $110 million
based on the closing price of Access Health Common Stock on May 29, 1998 and the
average closing price of Access Health Common Stock over the 20 consecutive
trading days ending May 29, 1998. All multiples for the Precedent Transactions
were based on public information available at the time of the announcement.
 
    No company, business or transaction compared in the Comparable Company
Analysis or Precedent Transaction Analysis is identical to Access Health,
InterQual or the Merger. Accordingly, an analysis of the results of the
foregoing is not entirely mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that could affect the acquisition, public
trading and other values of the Comparable Companies, Precedent Transactions or
the business segment, company or transactions to which they are being compared.
 
    CONTRIBUTION ANALYSIS.  BancAmerica Robertson Stephens analyzed the
respective contributions of Access Health and InterQual to the estimated
revenues, earnings before interest and taxes ("EBIT") and net income for the
years ended September 30, 1998 and 1999 of the combined company. This analysis
indicated that (i) in 1998, Access Health would contribute approximately 85% of
revenue, approximately 90% of EBIT and approximately 91% of net income and
InterQual would have contributed approximately 15% of revenue, approximately 10%
of EBIT and approximately 9% of net income of the combined company, and (ii) in
1999, Access Health would contribute approximately 83% of revenue, approximately
79% of EBIT and approximately 80% of net income and InterQual would contribute
approximately 17% of revenue, approximately 21% of EBIT and approximately 20% of
net income of the combined company. Based on the market value of Access Health
as of May 29, 1998, these percentages indicated implied equity valuations from
approximately $50 to $130 million for InterQual, as compared to the equity value
implied by the Merger Consideration of approximately $110 million based on the
closing price of Access Health Common Stock on May 29, 1998 and the average
closing price of Access Health Common Stock over the 20 consecutive trading days
ending May 29, 1998.
 
    DISCOUNTED CASH FLOW ANALYSIS.  BancAmerica Robertson Stephens performed a
discounted cash flow analysis of the after-tax cash flows of InterQual using
estimates from Access Health for the fiscal years 1998 through 2003. BancAmerica
Robertson Stephens first discounted the projected, after-tax cash flows through
December 31, 2007 using a range of discount rates from 15% to 17%. InterQual
after-tax cash-flows were calculated as the after-tax operating earnings of
InterQual adjusted to add back non-cash expenses and deduct uses of cash not
reflected in the income statement. BancAmerica Robertson Stephens then added to
the present value of the cash flows the terminal value of InterQual in the
fiscal year ending December 31, 2007, discounted back at the same discount rate.
The terminal value was computed by multiplying InterQual's projected earnings
before interest, taxes, depreciation and amortization in fiscal 2007 by terminal
multiples ranging from 7x to 8x. The range of terminal multiples selected
reflect BancAmerica Robertson Stephens's judgment as to an appropriate range of
multiples at the end of the referenced period. The discounted cash flow
valuation indicated implied equity valuations from approximately $120 to $147
million, as compared to the equity value implied by the Merger Consideration of
approximately $110 million based on the closing price of Access Health Common
Stock on May 29, 1998 and the average closing price of Access Health Common
Stock over the 20 consecutive trading days ending May 29, 1998.
 
    PRO FORMA EARNINGS ANALYSIS.  BancAmerica Robertson Stephens analyzed
certain pro forma effects resulting from the Merger, including, among other
things, the impact of the Merger on the projected earnings per share ("EPS") of
the combined company for the years ending September 30, 1998 and 1999. The
results of the pro forma earnings analysis suggested that the Merger would not
be expected to be accretive to the combined company's EPS until the first
quarter of fiscal 1999 and would likely be accretive to the combined company's
EPS in fiscal 1999.* The actual results achieved by the combined company may
vary from projected results and the variations may be material.
 
                                       44
<PAGE>
    OTHER FACTORS.  In rendering its opinion, BancAmerica Robertson Stephens
considered certain other factors and conducted certain other analyses,
including, among other things, a review of (i) the history of trading prices and
volume for Access Health Common Stock for the period May 29, 1997 to May 29,
1998; (ii) selected published analysts' reports on Access Health, including
analysts' estimates as to the earnings growth potential of Access Health; and
(iii) a cost of capital analysis for InterQual.
 
    While the foregoing summary describes certain analyses and factors that
BancAmerica Robertson Stephens deemed material in rendering the BancAmerica
Robertson Stephens Opinion, it is not a comprehensive description of all
analyses and factors considered by BancAmerica Robertson Stephens. The
preparation of a fairness opinion is a complex process that involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to partial analysis
summary description. BancAmerica Robertson Stephens believes that its analyses
must be considered as a whole and that selecting portions of its analyses and of
the factors considered by it, without considering all analyses and factors,
could create an incomplete and misleading view of the evaluation process
underlying the BancAmerica Robertson Stephens Opinion. Several analytical
methodologies were employed and no one method of analysis should be regarded as
critical to the overall conclusion reached by BancAmerica Robertson Stephens.
Each analytical technique has inherent strengths and weaknesses, and the nature
of the available information may further affect the value of particular
techniques. The conclusions reached by BancAmerica Robertson Stephens are based
on all analyses and factors taken as a whole and also on BancAmerica Robertson
Stephens' own experience and judgment. Such conclusions may involve significant
elements of subjective judgment and qualitative analysis. BancAmerica Robertson
Stephens therefore gives no opinion as to the value or merit standing alone of
any one or more parts of the analysis it performed. In performing its analyses,
BancAmerica Robertson Stephens considered general economic, market and financial
conditions and other matters, many of which are beyond the control of Access
Health and InterQual. Each of the analyses conducted by BancAmerica Robertson
Stephens was so conducted to arrive at a determination as to whether the Merger
Consideration was fair to Access Health from a financial point of view. In order
to make such a determination, BancAmerica Robertson Stephens selected and
conducted those analyses which it believes would provide indications of market
value and relative contribution. Each of the analyses conducted by BancAmerica
Robertson Stephens is customarily utilized by investment banks and financial
advisors in a determination of fairness. Based on its experience as a financial
advisor and investment bank, BancAmerica Robertson Stephens determined that each
of the Comparable Company, the Precedent Transaction Analysis, the Contribution
Analysis and the Discounted Cash Flow Analysis serves to indicate whether the
Merger Consideration is fair to Access Health from a financial point of view.
The analyses performed by BancAmerica Robertson Stephens are not necessarily
indicative of actual values or future results, which may be significantly more
or less favorable than those suggested by such analyses. Accordingly, analyses
relating to the value of a business do not purport to be appraisals or to
reflect the prices at which the business actually may be purchased, and such
estimates are inherently subject to uncertainty. Furthermore, no opinion is
being expressed as to the prices at which shares of Access Health Common Stock
may trade at any future time.
 
    Access Health engaged BancAmerica Robertson Stephens pursuant to the
Engagement Letter on December 29, 1997. The Engagement Letter provides that, for
its services, BancAmerica Robertson Stephens is entitled to receive an initial
fee of $162,500, due and payable to BancAmerica Robertson Stephens upon
execution of the Engagement Letter and a payment of $162,500 due and payable to
BancAmerica Robertson Stephens upon delivery of its fairness opinion to the
Access Health Board. If an updated opinion ("Updated Opinion") is requested at a
future date, Access Health agreed to pay BancAmerica Robertson Stephens an
additional fee of $75,000 for such Updated Opinion. Access Health has also
agreed to reimburse BancAmerica Robertson Stephens for its out-of-pocket
expenses and to indemnify and hold harmless BancAmerica Robertson Stephens and
its affiliates and any person, director, employee or agent of BancAmerica
Robertson Stephens or any of its affiliates, or any person controlling
BancAmerica Robertson Stephens or its affiliates for certain losses, claims,
damages, expenses and liabilities relating to or arising out of services
provided by BancAmerica Robertson Stephens as financial
 
                                       45
<PAGE>
advisor to Access Health. The terms of the fee arrangement with BancAmerica
Robertson Stephens, which Access Health and BancAmerica Robertson Stephens
believe are customary in transactions of this nature, were negotiated at arm's
length between Access Health and BancAmerica Robertson Stephens, and the Access
Health Board was aware of such fee arrangements.
 
    BancAmerica Robertson Stephens was retained based on BancAmerica Robertson
Stephens' experience as a financial advisor in connection with mergers and
acquisitions and in securities valuations generally, as well as BancAmerica
Robertson Stephens investment banking relationship and familiarity with Access
Health. In addition to acting as financial advisor to Access Health in
connection with the Merger, BancAmerica Robertson Stephens (formerly, "Robertson
Stephens & Company") acted as financial advisor to Informed Access Systems, Inc.
("Informed Access") in connection with the merger of Informed Access and Access
Health completed in November 1996. Pursuant to an engagement letter between
Robertson Stephens & Company and Informed Access, Robertson Stephens & Company
was compensated for its services rendered in connection with such transaction
with its usual and customary fee.
 
    In the ordinary course of business BancAmerica Robertson Stephens may
actively trade the equity securities of Access Health for its own account and
for the account of its customers and, accordingly, may at any time hold a long
or short position in such securities. Further, BancAmerica Robertson Stephens
maintains a market in the Access Health Common Stock and regularly publishes
research reports regarding the health care information services industry and the
business and securities of Access Health and other publicly traded companies in
the health care information services industry.
 
    BancAmerica Robertson Stephens is a nationally recognized investment banking
firm. As part of its investment banking business, BancAmerica Robertson Stephens
is frequently engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of securities, private placements and other purposes.
 
OPINION OF INTERQUAL'S FINANCIAL ADVISOR
 
   
    InterQual retained Volpe Brown Whelan to act as its financial advisor with
respect to the Merger. On June 1, 1998 Volpe Brown Whelan rendered its opinion
to the Board of Directors of InterQual to the effect that, as of May 29, 1998
and based on and subject to the matters stated in the opinion, the Merger
Consideration to be paid by Access Health to InterQual stockholders in the
Merger is fair from a financial point of view to InterQual. Volpe Brown Whelan
has consented to the inclusion and use of its opinion in this Proxy
Statement/Prospectus and Notice and Consent Solicitation Statement.
    
 
    THE FULL TEXT OF VOLPE BROWN WHELAN'S WRITTEN OPINION DATED MAY 29, 1998
WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED, AND LIMITATIONS ON
THE REVIEW UNDERTAKEN, IS ATTACHED AS ANNEX C AND IS INCORPORATED HEREIN BY
REFERENCE. THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF SUCH OPINION. HOLDERS OF INTERQUAL CAPITAL STOCK ARE URGED TO, AND
SHOULD, READ THIS OPINION CAREFULLY IN ITS ENTIRETY. THE ENGAGEMENT OF VOLPE
BROWN WHELAN AND ITS OPINION ARE FOR THE BENEFIT OF THE INTERQUAL BOARD AND ITS
OPINION WAS DELIVERED TO THE INTERQUAL BOARD IN CONNECTION WITH ITS
CONSIDERATION OF THE MERGER. VOLPE BROWN WHELAN'S OPINION ADDRESSES ONLY THE
FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW TO
INTERQUAL, AND IT DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER NOR DOES IT
CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF INTERQUAL CAPITAL STOCK AS TO HOW
TO VOTE WITH RESPECT TO THE MERGER.
 
    In arriving at its opinion, Volpe Brown Whelan:
 
 (i) reviewed the Amended and Restated Agreement and Plan of Reorganization
     dated as of June 4, 1998 by and among Access Health, Access Acquisition
     Corp. 98A and InterQual;
 
                                       46
<PAGE>
 (ii) reviewed the Affiliate/Voting Agreement dated February 13, 1998 by and
      among Access Health, InterQual and a stockholder of InterQual who may be
      determined to be an affiliate;
 
 (iii) reviewed the form of registration rights agreement to be completed at
       closing between Access Health and the stockholders of InterQual;
 
 (iv) reviewed the form of employment agreements between Access Health and
      certain InterQual employees;
 
 (v) reviewed the form of separation and consulting agreements between Access
     Health and Charles M. Jacobs and Access Health and Randolph W. Seed, M.D.;
 
 (vi) interviewed management of InterQual and Access Health concerning the
      business prospects, financial outlook and operating plans of each company
      individually and combined;
 
 (vii) reviewed certain historical and projected InterQual and Access Health
       financial statements and other relevant financial and operating data of
       InterQual and Access Health prepared by the respective management teams;
 
(viii) considered the potential valuation which public market investors might
       accord InterQual in the context of an initial public offering of its
       securities;
 
 (ix) reviewed the valuation of selected publicly-traded companies deemed
      comparable and relevant to InterQual;
 
 (x) reviewed, to the extent publicly-available, the financial terms of selected
     merger and acquisition transactions deemed comparable and relevant to the
     Merger;
 
 (xi) reviewed the relevant contribution each of InterQual and Access Health is
      making to the combined company in terms of financial results and compared
      the results of this analysis with the pro forma ownership of the combined
      company;
 
 (xii) performed a discounted cash flow analysis of InterQual as a stand-alone
       entity based upon the financial projections of InterQual management;
 
(xiii) performed a pro forma financial impact analysis of the combined entity,
       based upon financial projections provided by InterQual and financial
       projections provided by Access Health and reviewed by InterQual; and
 
 (xiv) performed other such studies, analyses and inquiries and considered other
       such information as it deemed relevant.
 
    No limitations were imposed by the InterQual Board on Volpe Brown Whelan
with respect to the investigations made or procedures followed by it in
furnishing its opinion. The Merger Consideration was determined through
negotiations between the managements of Access Health and InterQual. Volpe Brown
Whelan did not recommend to the InterQual Board that a specific exchange ratio
should constitute the Merger Consideration.
 
    In rendering its opinion, Volpe Brown Whelan relied without independent
verification upon the accuracy and completeness of all of the financial,
accounting, legal, tax, operating and other information provided to Volpe Brown
Whelan by InterQual and Access Health and relied upon the assurances of
InterQual and Access Health 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 Volpe Brown Whelan either incomplete or
misleading. InterQual also retained outside legal, accounting and tax advisors
to advise on matters relating to the Merger. Accordingly, Volpe Brown Whelan
relied on their advice and expresses no opinion on such matters. With respect to
the projected financial data of InterQual and Access Health, all of which was
provided by the management of InterQual or Access Health, as well as the
combined business plan
 
                                       47
<PAGE>
(including cost savings projected to result from the Merger), Volpe Brown Whelan
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 InterQual and Access Health managements as to the future
financial performance of each company separately and as a combined company.
Volpe Brown Whelan has not made any independent appraisals or valuations of any
assets of InterQual or Access Health, nor has Volpe Brown Whelan been furnished
with any such appraisals or valuations. In addition, Volpe Brown Whelan assumed
that the Merger would be accounted for as a pooling of interests business
combination for financial reporting purposes and as a tax-free reorganization
within the meaning of Section 368(a) of the Code. Volpe Brown Whelan's opinion
is necessarily based on economic, market and other conditions as in effect on,
and the information made available to Volpe Brown Whelan as of, the date it
rendered its opinion.
 
    The following is a brief summary of the material analyses performed by Volpe
Brown Whelan in connection with Volpe Brown Whelan's presentation and opinion to
the InterQual Board.
 
    REVIEW OF COMPETING PROPOSALS.  Volpe Brown Whelan analyzed the five initial
indications of interest and the subsequent four final proposals received by
InterQual from interested parties in the process of the competitive auction.
Volpe Brown Whelan evaluated the proposals on the basis of the value of the
consideration proposed, the form of the consideration, the proposed terms of the
combination transaction and any contingent liabilities which would reside with
InterQual stockholders. Volpe Brown Whelan concluded in that analysis that the
terms of the merger proposed by Access Health and which were ultimately agreed
in the Merger were the most attractive from a financial point of view to
InterQual.
 
    COMPARABLE PUBLICLY-TRADED COMPANY ANALYSIS.  Volpe Brown Whelan compared
certain financial information of InterQual with that of a group of
publicly-traded companies selected by Volpe Brown Whelan based on similarity of
business lines, relative operating size and profitability and market
capitalization. The comparable publicly-traded companies included HCIA, Inc.,
MECON, Inc., Medirisk, Inc., QuadraMed Corp., Summit Medical Systems, Inc.,
Transition Systems, Inc., Access Health, Inc. and Health Systems Design Corp.
(collectively, the "Public Comparables"). The financial information reviewed
included stock price in relation to (i) earnings per share ("EPS") for the
latest twelve month period ("L12M"), (ii) forecasted 1998 EPS and (iii)
forecasted 1999 EPS and (iv) book value of shareholders' equity as well as
enterprise value (defined as market capitalization plus funded debt less cash)
in relation to L12M revenue, L12M earnings before depreciation, amortization,
interest and taxes ("EBITDA") and L12M earnings before interest and taxes
("EBIT") (collectively, the "Reviewed Information"). Forecasted 1998 and 1999
EPS for the Public Comparables were based on published estimates by research
organizations, including those of Volpe Brown Whelan. Volpe Brown Whelan noted
that, based on closing stock prices and earnings estimates as of May 28, 1998,
the Public Comparables traded in a range of 26.3 to 61.9 times L12M earnings
(with a median of 34.1 times), 21.5 to 32.1 times 1998 forecast earnings (with a
median of 28.7 times) and 14.9 to 25.7 times 1999 forecast earnings (with a
median of 19.5 times) and 0.8 to 14.2 times book value (with a median of 4.0
times). The enterprise value of the Public Comparables implied from the stock
prices provided a range of 1.2 to 7.4 times L12M revenues (with a median of 3.8
times) and 4.2 to 19.5 times L12M EBITDA (with a median of 13.2 times) and 4.6
to 26.6 times L12M EBIT (with a median of 16.4 times). The analysis of Public
sComparables yields a median of low values for InterQual of $11.7 million and a
median of high values of $27.5 million with a median value of $15.4 million and
a mean value of $63.4 million (without giving effect to a change of control
premium), as compared to the enterprise value implied by the Merger
Consideration of approximately $113.6 million based on the closing price of
Access Health Common Stock on May 28, 1998. Because of the inherent differences
between the business, operations and prospects of InterQual and the businesses,
operations and prospects of the Public Comparables, Volpe Brown Whelan believed
that it was inappropriate to, and therefore did not, rely solely on the
quantitative results of the analysis and, accordingly, also made qualitative
judgments concerning differences between InterQual and the Public Comparables
that would affect the valuation.

    IPO ANALYSIS:  Volpe Brown Whelan considered the potential valuation which
public market investors might accord InterQual in the context of a public
offering. The analysis makes certain pro-forma adjustments to InterQual's
prospective financial performance to reflect its operations and cost structure
as a publicly traded and independent entity. Such financial information was
compared to the Reviewed Information of the Public Comparables. Volpe Brown
Whelan made an adjustment to reflect the likely discount at which public market
investors would subscribe new equity in an IPO. The IPO analysis indicated a
pre-money mean of low values for InterQual of $2.9 million and a mean of high
values of $109.1 million, with a mean of $38.3 million. In Volpe Brown Whelan's
view the most appropriate valuation metric was the mean of the valuations
implied by multiples of 1998 and 1999 net income which indicated a mean value of
$84.4 million as compared to the enterprise value implied by the Merger
Consideration of approximately $113.6 million based on the closing price of
Access Health Common Stock on May 28, 1998.
 
    COMPARABLE MERGER AND ACQUISITION TRANSACTIONS.  Volpe Brown Whelan reviewed
the financial terms, to the extent publicly available, of 30 selected merger and
acquisition transactions that Volpe Brown Whelan deemed comparable and relevant
to the Merger. The transaction value of these transactions ranged from 12.6 to
73.7 times trailing net income (with a median of 39.4). The enterprise value of
these transactions ranged from 0.5 to 11.8 times trailing revenue (with a median
of 3.5) and 8.2 to 69.6 times trailing EBIT (with a median of 31.0). The
analysis of selected merger and acquisition transactions yields a median of low
values for InterQual of $5.8 million and a median of high values of $49.3
million with a median value of $21.9 million and a mean value of $33.9 million,
as compared to the enterprise value implied by the Merger Consideration of
approximately $113.6 million based on the closing price of Access Health Common
Stock on May 28, 1998. The reasons for and circumstances surrounding each of the
selected transactions were specific to that transaction and as a result the
range of values yielded by this analysis was wide. No transaction or business
compared in the selected comparable merger and acquisition transactions is
identical to InterQual, Access Health or the Merger. Accordingly, Volpe Brown
Whelan did not rely solely on the quantitative results of this analysis and also
made qualitative judgments concerning differences between the selected
transactions and the Merger that would affect the valuation.
 
    CONTRIBUTION ANALYSIS.  Volpe Brown Whelan reviewed certain historical and
forecasted financial information (including revenue, gross profit, EBITDA, EBIT,
net income and book value) for InterQual and Access Health and the pro forma
combined entity resulting from the Merger. Volpe Brown Whelan adjusted the
relative contributions of revenue, gross profit, EBITDA and EBIT to reflect the
differences in capital structures of the two companies. Volpe Brown Whelan
analyzed the relative contributions of InterQual and Access Health based on
historical financial performance for the fiscal year ended September 30, 1997,
L12M to March 31, 1998 and forecasted financial performance for fiscal years
ended September 30, 1998 and 1999. Based on the foregoing analysis, Volpe Brown
Whelan concluded that InterQual would be contributing 11.1% of revenue in fiscal
year 1997, 12.1% in L12M, 13.1% in forecast fiscal year 1998 and 14.6% in
forecast fiscal year 1999; 15.1% of gross profit in fiscal year 1997, 17.1% in
L12M, 19.7% in forecast fiscal year 1998 and 22.0% in forecast fiscal year 1999;
2.7% of EBITDA in fiscal year 1997, 3.1% in L12M, 7.7% in forecast fiscal year
1998 and 17.8% in forecast fiscal year 1999; 2.1% of EBIT in fiscal year 1997,
2.5% in L12M, 8.1% in forecast fiscal year 1998 and 19.8% in forecast fiscal
year 1999; 1.7% of net income in fiscal year 1997, 2.1% in L12M, 7.8% in
forecast fiscal year 1998 and 20.0% in forecast fiscal year 1999; and 0.5% of
book value in fiscal year 1997, 0.8% in L12M, 2.3% in forecast fiscal year 1998
and 6.6% in forecast fiscal year 1999 in comparison to the 17.9% of the
outstanding common equity of the combined entity that the InterQual stockholders
would receive in the Merger. Volpe Brown Whelan determined that such ratios
implied a value range for InterQual from $3.9 million to $144.9 million with a
median of $45.6 million and a mean of $59.2 million. In Volpe Brown Whelan's
view the most appropriate valuation metric was the mean of the valuations
implied by the contribution to 1998 and 1999 EBIT and net income, which
indicated a mean value of $86.8 million, as compared to the enterprise value
implied by the Merger Consideration of approximately $113.6 million based on the
closing price of Access Health Common Stock on May 28, 1998.
 
                                       49

    DISCOUNTED CASH FLOW ANALYSIS.  Volpe Brown Whelan performed a discounted
cash flow analysis of InterQual based on certain financial projections provided
by InterQual for the periods 1998 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. Volpe Brown Whelan calculated terminal values by applying an exit
multiple on 2002 net income and the cash flow streams and terminal values were
then discounted to the present using a range of discount rates representing an
estimated range of the weighted average cost of capital for InterQual. Based on
this analysis, Volpe Brown Whelan calculated values of InterQual ranging from
$130.6 million to $294.3 million as compared to the enterprise value implied by
the Merger Consideration of approximately $113.6 million based on the closing
price of Access Health Common Stock on May 28, 1998. Because the discounted cash
flow analysis is based on projections over an extended period of time, which are
inherently subject to uncertainty and factors beyond the control of InterQual,
Volpe Brown Whelan ascribed only limited weight to the results of this analysis
in its overall evaluation of the fairness of the consideration.
 
    PRO FORMA FINANCIAL IMPACT ANALYSIS.  Volpe Brown Whelan analyzed the pro
forma impact of the Merger on Access Health's earnings per share for the fiscal
years ended September 30, 1998 and 1999. The analysis was performed utilizing
stand-alone operating estimates provided by the management teams of InterQual
and Access Health. The operating estimates included stand-alone estimates for
InterQual and Access Health as well as transaction-related costs and projected
cost savings resulting from the Merger. Volpe Brown Whelan noted that based on
such projections, the Merger would be not be expected to be accretive to Access
Health's earnings per share in the fiscal year 1998 and would be accretive to
Access Health's earnings per share in fiscal year 1999. The actual results
achieved by the combined company may vary from projected results and the
variations may be material.
 
    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, Volpe Brown Whelan 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, Volpe Brown Whelan 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 Volpe Brown
Whelan's view of the actual value of InterQual.
 
    The analyses performed by Volpe Brown Whelan are not necessarily indicative
of actual value, which may be significantly more or less favorable than
suggested by such analyses. Such analyses were prepared solely as part of Volpe
Brown Whelan's analysis of the fairness of the consideration from a financial
point of view to InterQual. The analyses do not purport to be appraisals or to
reflect the prices at which InterQual might actually be sold. In addition, as
described above, Volpe Brown Whelan's opinion and presentation to the InterQual
Board was one of many factors taken into consideration by the InterQual Board in
making its determination to approve the Merger. Consequently, the Volpe Brown
Whelan analyses described herein should not be viewed as determinative of the
opinion of the InterQual Board with respect to the value of InterQual or of
whether the InterQual Board or the Access Health Board would have been willing
to agree to a different level of consideration.
 
    Volpe Brown Whelan is a nationally recognized investment banking firm and
was selected by InterQual based on Volpe Brown Whelan's experience and expertise
as a financial advisor in connection with mergers and acquisitions and in
securities valuations generally. Volpe Brown Whelan, 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, Volpe Brown Whelan and its affiliates may actively trade the equity
securities of Access Health 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.
 
                                       50
<PAGE>
    Volpe Brown Whelan will receive a fee of $325,000 for rendering its opinion,
no portion of which is conditioned upon the opinion being favorable. $250,000 of
that fee will be credited against an additional fee to be paid to Volpe Brown
Whelan upon the closing of the Merger. Such additional fee is based on the
aggregate value of the consideration received by InterQual stockholders at the
date of closing of the Merger. Based on the Access Health stock price as of May
28, 1998 and the Merger Consideration, Volpe Brown Whelan's additional fee would
be $2.2 million. Terms of the fee arrangement with Volpe Brown Whelan which
InterQual and Volpe Brown Whelan believe are customary in transactions of this
nature, were negotiated at arm's length between InterQual and Volpe Brown
Whelan, and the InterQual Board was aware of such fee arrangements. In addition,
InterQual has agreed to reimburse Volpe Brown Whelan for its out-of-pocket costs
and expenses and to indemnify Volpe Brown Whelan and its affiliates against
certain liabilities and expenses.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In considering the recommendation of the InterQual Board with respect to the
Merger, InterQual stockholders should be aware that certain members of the
InterQual Board and management have certain interests in the Merger that are in
addition to the interests of InterQual stockholders generally. The InterQual
Board was aware of these interests and considered them, among other factors, in
approving the Merger Agreement. These interests are as follows:
 
    Francis Newbury, a director of InterQual, has performed certain financial
advisory services relating to the Merger on behalf of InterQual and will receive
a fee of 0.25% of the value of the Merger Consideration from InterQual. Assuming
that the market value of Access Health Common Stock at the Effective Time is
equal to the market value as of the close of business on February 13, 1998
(although there can be no assurance of such an assumption; the actual market
value of Access Health Common Stock, and Mr. Newbury's fee, may vary
materially), Mr. Newbury will receive $396,825.
 
    In connection with the Merger Agreement, Charles M. Jacobs, InterQual's
Chief Executive Officer, and Randolph W. Seed, M.D., both of whom are members of
the InterQual Board will enter into separation and consulting agreements with
Access Health. The separation and consulting agreements generally provide for
separation consideration for termination of the individuals' employment with
InterQual, an initial term for consulting services, a fixed consulting fee and a
noncompetition clause which restricts such consultant from engaging in
activities that compete with the businesses of Access Health and InterQual
during a period beginning with the effective date of the separation and
consulting agreement and ending two years after the termination of the
agreement. In addition, under the separation and consulting agreement Access
Health will also provide COBRA benefits to Charles M. Jacobs for the shorter of
two years or until he finds employment providing him with health benefits and
certain business and travel allowances. The following table summarizes the basic
terms of the separation and consulting agreements:

</TABLE>
 
    Three executive officers of InterQual will, and five additional InterQual
officers are expected to, enter into employment agreements with Access Health in
connection with the Merger Agreement.* The employment agreements generally
provide for: a fixed term of employment; an initial base compensation subject to
annual review for increases; eligibility for an incentive bonus of up to a
specified percentage of base compensation; the grant of incentive stock options
under the Access Health Stock Option Plan; and a noncompetition clause which
restricts such employee from engaging in activities that compete with the
businesses of Access Health and InterQual during a period beginning with the
effective date of the employment agreement and ending two years after the
termination of the agreement. In the event that the five additional InterQual
officers do not enter into employment agreements, InterQual is required to have
 
                                       51

such officers execute noncompetition agreements containing similar noncompete
provisions as the employment agreements. The following table summarizes the

EFFECTIVE TIME
 
    The Merger Agreement provides that the Merger will become effective upon the
filing of a Certificate of Merger with the Secretary of State of Delaware in
accordance with the DGCL. It is anticipated that if all conditions of the Merger
have been fulfilled or waived, the Effective Time will occur on or about June
30, 1998, or on a date as soon as practicable thereafter.
 
MANNER AND BASIS OF CONVERTING SHARES
 
    Subject to the terms and conditions of the Merger Agreement, as of the
Effective Time, by virtue of the Merger and without any action on the part of
Merger Sub, InterQual or the holder of any shares of InterQual Capital Stock,
the following will occur:
 
    CONVERSION OF INTERQUAL CAPITAL STOCK.  Under the terms of the Merger,
4,290,000 shares of Access Health Common Stock will be exchanged for the
outstanding shares of InterQual Capital Stock. The Merger Consideration is
subject to an increase in the event that the value of the number of shares of
Access Health Common Stock to be exchanged in the Merger is less than $130
million, computed using the Market Price. In the event such increase is
necessary, the number of shares will be increased by the number of shares equal
to the lesser of (A) fifty percent (50%) of the amount obtained from: (1) the
quotient of $130 million and the Market Price of Access Health Common stock,
less (2) 4,290,000, and (B) 250,000.
 
    Each share of InterQual Class A Common Stock and each share of InterQual
Class B Common Stock issued and outstanding immediately prior to the Effective
Time (other than any shares held by a holder who has demanded and perfected
appraisal rights for such shares in accordance with the applicable provisions of
the DGCL and who has not withdrawn or lost such rights) will be canceled and
extinguished and be converted automatically into the right to receive that
number of shares of Access Health Common Stock equal to: (1) in the case of
InterQual Class A Common Stock, the Exchange Ratio or (2) in the case of
InterQual Class B Common Stock, the product of .99 and the Exchange Ratio.
InterQual stockholders shall be asked to surrender each certificate representing
InterQual Class A and Class B Common Stock in the manner provided in a Letter of
Transmittal to be sent to each record holder of InterQual Capital Stock promptly
following the Effective Time. After the InterQual stockholders have surrendered
such certificates representing InterQual Class A or Class B Common Stock, Access
Health will cause to be issued to such stockholders certificates of Access
Health Common Stock representing their portion of the Merger Consideration,
subject to the escrow provisions of the Merger Agreement described under the
section entitled "Approval of the Merger and Related Transactions--Escrow Fund"
below.
 
                                       52
<PAGE>
    The Exchange Ratio will be equal to the quotient obtained by dividing (x)
4,290,000 (subject to adjustment as described below) by (y) the sum of the
aggregate number of shares of InterQual Class A Common Stock and the aggregate
number of shares of InterQual Class B Common Stock multiplied by 0.99
outstanding immediately prior to the Effective Time. If the Market Price is less
than $30.3030303, the 4,290,000 numerator in the Exchange Ratio may be increased
by the number of shares equal to the lesser of (A) fifty percent (50%) of the
amount obtained from: (1) the quotient of $130 million and the Market Price of
Access Health Common Stock, less (2) 4,290,000, and (B) 250,000. Thus, the
Exchange Ratio may vary depending on the Market Price. The Exchange Ratio will
be appropriately adjusted to reflect the effect of any stock split, stock
dividend, reorganization, recapitalization or the like with respect to the
Access Health Common Stock occurring after February 13, 1998 and prior to the
Effective Time.
 
    The number of shares of Access Health to be exchanged for each share of
InterQual Class A and Class B Common Stock will depend on the Market Price.
Assuming that the Market Price at the Effective Time is at least $30.3030303 per
share (although there can be no assurance as to the foregoing) and assuming all
outstanding options to purchase InterQual Capital Stock have been exercised in
accordance with their terms, each share of InterQual Class A Common Stock
exchanged in the Merger will be converted into the right to receive
approximately 360.420 shares of Access Health Common Stock and each share of
InterQual Class B Common Stock exchanged in the Merger will be converted into
the right to receive approximately 356.816 shares of Access Health Common Stock.
 
    FRACTIONAL SHARES.  No fraction of a share of Access Health Common Stock
will be issued, but in lieu thereof, each holder of shares of InterQual Capital
Stock who would otherwise be entitled to a fraction of a share of Access Health
Common Stock (after aggregating all fractional shares of Access Health Common
Stock to be received by such holder) shall be entitled to receive from Access
Health an amount of cash (rounded to the nearest whole cent) equal to the
product of (i) such fraction and (ii) the closing price of a share of Access
Health Common Stock on the trading day immediately prior to the closing date, as
reported on Nasdaq.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
    An aggregate of approximately 4,290,000 shares of Access Health Common Stock
will be issued to InterQual stockholders in the Merger. The number of shares
exchanged is subject to an increase in the event that the value of the number of
shares of Access Health Common Stock to be exchanged in the Merger is less than
$130 million, computed using the Market Price of Access Health Common Stock. In
the event such increase is necessary, the number of shares will be increased by
the number of shares equal to the lesser of (A) fifty percent (50%) of the
amount obtained from: (1) the quotient of $130 million and the Market Price of
Access Health Common Stock, less (2) 4,290,000, and (B) 250,000. Based upon the
number of shares of Access Health Common Stock issued and outstanding as of May
15, 1998, a Market Price of at least $30.3030303, and after giving effect to the
issuance of Access Health Common Stock in connection with the Merger (assuming
no exercise of appraisal rights and assuming all shares will be released from
the Escrow Fund), the former holders of InterQual Capital Stock would hold
approximately 18.4% and Charles M. Jacobs, an affiliate of InterQual, would
become the beneficial owner of approximately 8.7% of Access Health's total
issued and outstanding shares, respectively. The foregoing numbers of shares and
percentages are subject to change in the event that the Merger Consideration is
less than $130 million, computed using the Market Price. There can be no
assurance as to the Market Price of the Access Health Common Stock to be used in
calculating the Merger Consideration.
 
ESCROW FUND
 
    In connection with the Merger, at the Effective Time, the Escrow Shares will
be registered in the name of and deposited with The First National Bank of
Chicago, as Escrow Agent, such deposit to constitute the Escrow Fund. The Escrow
Shares will be the number of shares of Access Health Common Stock equal to the
product of (i) 0.05 and (ii) the number of shares of Access Health Common Stock
issuable in connection with the Merger. The Escrow Shares will be contributed to
the Escrow Fund on
 
                                       53
<PAGE>
behalf of each holder of InterQual Capital Stock at the Effective Time in
proportion to the aggregate number of shares of Access Health Common Stock that
such holder would otherwise be entitled under the Merger Agreement. The Escrow
Fund will be available to compensate Access Health for any losses incurred by
Access Health or for which Access Health would otherwise be liable as a result
of any inaccuracy or breach of a representation or warranty of InterQual
contained in the Merger Agreement or any failure by InterQual to perform or
comply with any covenant contained therein relating to unresolved contingencies
existing at the Effective Time. The Escrow Fund will also be used to pay Excess
Expenses, which are any third party fees and expenses in excess of $4 million
that have been incurred by InterQual in connection with the Merger without
regard to the Escrow Threshold. Stockholders will have voting rights with
respect to the Escrow Shares while in escrow, and will receive dividends, if
any, attributable to the Escrow Shares currently, although in the event that
Escrow Shares are to be delivered from the Escrow Fund to Access Health, any
dividends received on such delivered shares shall be returned to the Escrow Fund
for distribution to Access Health. Access Health may not receive any shares from
the Escrow Fund for breach of a representation and warranty or covenant unless
and until cumulative losses in excess of the Escrow Threshold have been
suffered, in which case Access Health may recover from the Escrow Fund the
entire amount of such cumulative losses. Access Health may also receive shares
from the Escrow Fund to pay for Excess Expenses. For the purpose of compensating
Access Health for its losses or Excess Expenses, the Escrow Shares will be
valued at the closing price of Access Health Common Stock as reported by the
Nasdaq on the trading day prior to the closing date of the Merger. Subject to
resolution of unsatisfied claims of Access Health, the Escrow Fund will
terminate six months following the closing date of the Merger.
 
    BY APPROVING THE MERGER AGREEMENT, INTERQUAL STOCKHOLDERS WILL BE DEEMED TO
HAVE CONSENTED TO THE APPOINTMENT OF CHARLES M. JACOBS, A DIRECTOR AND
STOCKHOLDER OF INTERQUAL, TO ACT AS THE SECURITYHOLDER AGENT ON BEHALF OF
INTERQUAL'S STOCKHOLDERS TO DELIVER SHARES HELD IN ESCROW TO ACCESS HEALTH IN
SATISFACTION OF CLAIMS BROUGHT BY ACCESS HEALTH, TO OBJECT TO SUCH DELIVERIES,
TO AGREE TO, TO NEGOTIATE AND TO ENTER INTO SETTLEMENTS AND COMPROMISES WITH
RESPECT TO SUCH CLAIMS, AND TO TAKE CERTAIN OTHER ACTION ON BEHALF OF
INTERQUAL'S STOCKHOLDERS, ALL AS MORE FULLY DESCRIBED IN ARTICLE VII OF THE
MERGER AGREEMENT. SEE ARTICLE VII OF THE MERGER AGREEMENT FOR A MORE DETAILED
EXPLANATION OF THE ESCROW FUND AND RIGHTS WITH RESPECT THERETO.
 
LEGAL STRUCTURE OF THE MERGER
 
    Under the Merger Agreement, Merger Sub, a wholly-owned subsidiary of Access
Health formed for this purpose, will merge with and into InterQual with
InterQual being the surviving corporation of the Merger (the "Surviving
Corporation"). The Certificate of Incorporation of Merger Sub in effect
immediately prior to the Effective Time will become the Certificate of
Incorporation of the Surviving Corporation, the Bylaws of Merger Sub will become
the Bylaws of the Surviving Corporation and the Board of Directors of Merger Sub
will become the initial Board of Directors of the Surviving Corporation. Access
Health and InterQual shall each use its reasonable efforts to cause the Merger
to be treated as a reorganization within the meaning of Section 368 of the Code.
 
CONDUCT OF INTERQUAL'S BUSINESS PRIOR TO THE MERGER
 
    Under the Merger Agreement, InterQual has agreed, during the period from the
date of the Merger Agreement and continuing until the earlier of the termination
of the Merger Agreement pursuant to its terms or the Effective Time, except as
contemplated by the Merger Agreement or to the extent that Access Health shall
otherwise consent in writing, which consent shall not be unreasonably withheld,
to carry on its business in the usual, regular and ordinary course in
substantially the same manner as heretofore conducted, to pay its debts and
taxes when due, to pay or perform other obligations when due, and, to the extent
consistent with such business, to use all reasonable efforts consistent with
past practice and policies to preserve intact its present business organization,
keep available the services of its present officers and key employees and
preserve their relationships with customers, suppliers, distributors, licensors,
licensees,
 
                                       54
<PAGE>
and others having business dealings with it, all with the goal of preserving
unimpaired its goodwill and ongoing business at the Effective Time. Following
the date of the Merger Agreement, InterQual shall promptly notify Access Health
of any material event or occurrence or emergency not in the ordinary course of
its business, and any event involving or adversely affecting InterQual or its
business. Except as expressly contemplated by the Merger Agreement, InterQual
shall not, without the prior written consent of Access Health, which consent
shall not be unreasonably withheld:
 
        (a) enter into any material commitment or transaction not in the
    ordinary course of business;
 
        (b) transfer to any person or entity any material rights to InterQual
    intellectual property rights (other than pursuant to end-user licenses in
    the ordinary course of business);
 
        (c) enter into any material agreements (or material amendments thereto)
    pursuant to which any other party is granted marketing, distribution or
    similar rights of any type or scope with respect to any products of

CONDUCT OF ACCESS HEALTH'S BUSINESS PRIOR TO THE MERGER
 
    Under the Merger Agreement, Access Health has agreed, during the period from
the date of the Merger Agreement and continuing until the earlier of the

otherwise consent in writing, which consent shall not be unreasonably withheld,
to carry on its business in the usual, regular and ordinary course in
substantially the same manner as heretofore conducted to pay its debts and taxes
when due, to pay or perform other obligations when due, and, to the extent
consistent with such business, to use all reasonable efforts consistent with
past practice and policies to preserve intact its present business organization,
keep available the services of its present officers and key employees and
preserve their relationships with customers, suppliers, distributors, licensors,
licensees, and others having business dealings with it, all with the goal of
preserving unimpaired its goodwill and ongoing businesses at the Effective Time.
Following the date of the Merger Agreement, Access Health shall promptly notify
InterQual of any materially negative event related to Access Health or its
business.

assets (excluding equity-based compensation for employees and prospective
employees (collectively, "Equity Compensation")), (b) provide information with

Compensation), or (d) make or authorize any statement, recommendation or
solicitation in support of any possible acquisition of InterQual or any of its

<PAGE>
InterQual will also have ceased and caused to be terminated any such contracts
or negotiations with third parties relating to any such transaction or proposed
transaction.
 
    In addition to the foregoing, InterQual has agreed that if it receives prior
to the Effective Time or the termination of the Merger Agreement any offer or
other proposal, as applicable, relating to any of the above, it shall promptly
notify Access Health thereof, and will provide information as to the identity of
the offeror or the party making any such offer or proposal and the specific
terms of such offer or proposal, as the case may be, and such other information
related thereto as Access Health may reasonably request.
 
EXPENSES; TERMINATION FEES
 
    In the event the Merger is not consummated, all fees and expenses incurred
by a party in connection with the Merger shall be the obligation of the party
incurring such fees and expenses. In the event the Merger is consummated, all
reasonable fees and expenses incurred by the InterQual in connection with the
Merger shall be assumed by and paid for the Access Health upon the Effective
Time; provided, however, that any legal, accounting, financial advisory,
consulting and all other fees and expenses of third parties in excess of
$4,000,000 shall be deducted from the Escrow Fund without regard to the $750,000
Escrow Threshold specified in the Merger Agreement. See "Approval of the Merger
and Related Transactions-- Escrow Fund."
 
    The Merger Agreement provides that InterQual will pay Access Health a
termination fee of $3.9 million in the event that the closing of the Merger does
not occur, the Merger Agreement is terminated, Access Health is not in material
breach of its obligations under the Merger Agreement and one of the following
events: (i) InterQual has willfully breached a representation, warranty,
covenant or agreement contained in the Merger Agreement giving rise to a
material adverse change in the business, results of operations or financial
prospects of InterQual; (ii) the Merger has been submitted to a vote of
InterQual's stockholders and the stockholders of InterQual fail to approve the
Merger by the requisite vote; or (iii) the InterQual Board fails to recommend or
changes its recommendation concerning the Merger, or shall disclose, in any
manner, its intention not to recommend or to change such recommendation.

such party's sole and exclusive remedy under any of the conditions cited in the
prior two paragraphs, except that if Access Health is entitled to receive such
termination fee, InterQual did not have the right to terminate the Merger
Agreement based on the price of Access Health Common Stock, and InterQual enters
into an agreement or other arrangement with a third party to effect a merger or
similar transaction within six months of the date of termination of the Merger
Agreement, then Access Health will also be entitled to seek any other rights or
remedies under law or equity against InterQual.

TERMINATION
 
    The Merger Agreement provides that it may be terminated and the Merger
abandoned at any time prior to the Effective Time: (a) by mutual consent of
Access Health and InterQual; (b) by Access Health or InterQual if: (i) the
Effective Time has not occurred by July 3, 1998 (provided that the right to
terminate the Merger Agreement under this clause (b) (i) shall not be available
to any party whose willful failure to fulfill any obligation under the Merger
Agreement has been the cause of, or resulted in, the failure of the Effective
Time to occur on or before such date); (ii) there shall be a final
non-appealable order of a federal or state court in effect preventing
consummation of the Merger; (iii) there shall be any statute, rule, regulation
or order enacted, promulgated or issued or deemed applicable to the Merger by
any governmental entity that would make consummation of the Merger illegal; or
(iv) the approval of the Merger by InterQual's stockholders or the approval of
the Share Proposal by Access Health's stockholders shall not have been obtained
at a meeting duly convened therefor or any adjournment thereof or by written
consent, as the case may be; (c) by Access Health or InterQual if there shall be
any action taken, or any statute, rule, regulation or order enacted, promulgated
or issued or deemed applicable to the Merger, by any governmental entity, which
would: (i) prohibit Access Health's or InterQual's ownership or operation of any
portion of the business of InterQual or (ii) compel Access Health or InterQual
to dispose of or hold separately, as a result of the Merger, any portion of the
business or assets of InterQual or Access Health; in either case, the
unavailability of which assets or business would have a material adverse effect
on Access Health or would reasonably be expected to have a material adverse
effect on Access Health's ability to realize the benefits expected from the
Merger; (d) by Access Health if it is not in material breach of its obligations
under the Merger Agreement and there has been a breach of any representation,
warranty, covenant or agreement contained in the Merger Agreement on the part of
InterQual and as a result of such breach certain conditions to the Merger set
forth above would not then be satisfied; provided, however, that if such breach
is curable by InterQual within thirty days through the exercise of its
reasonable best efforts, then for so long as InterQual continues to exercise
such reasonable best efforts Access Health may not terminate the Merger
Agreement under this clause (d) unless such breach is not cured within thirty
days (but no cure period shall be required for a breach which by its nature
cannot be cured); (e) by InterQual if it is not in material breach of its
obligations under the Merger Agreement and there has been a breach of any
representation, warranty, covenant or agreement contained in the Merger
Agreement on the part of Access Health or Merger Sub and as a result of such
breach certain conditions to the Merger set forth above would not then be
satisfied; provided, however, that if such breach is curable by Access Health or
Merger Sub within thirty days through the exercise of its reasonable best
efforts, then for so long as Access Health or Merger Sub continues to exercise
such reasonable best efforts InterQual may not terminate the Merger Agreement
under this condition unless such breach is not cured within thirty days (but no
cure period shall be required for a breach which by its nature cannot be cured);
(f) by Access Health if an event having a material adverse effect on InterQual
shall have occurred after the date of the Merger Agreement; (g) by InterQual if
an event having a material adverse effect on Access Health shall have occurred
after the date of the Merger Agreement; (h) by Access Health if the InterQual
Board shall have failed to recommend or change its recommendation concerning the
Merger or shall have disclosed in any manner its intention to change such
recommendation; (i) by InterQual if the Access Health Board shall have failed to
recommend or change its recommendation concerning the Merger or shall have
disclosed in any manner its intention to change such recommendation; and (j) by
InterQual for such time but only during such time that the average closing price
of a share of Access Health Common Stock over any 20 consecutive trading days as
reported on Nasdaq is less than $27.14 per share (as appropriately adjusted for
any stock splits, consolidations, stock dividends, reorganization,
recapitalization or other like changes).
 
    At any time when InterQual is eligible to exercise its termination right
pursuant to condition (j) above, Access Health may provide InterQual with a
written request (the "Termination Inquiry") inquiring as to InterQual's
intention to terminate the Merger. Upon receipt of such request, InterQual shall
have three business days to provide Access Health with notice regarding its
intention to exercise its termination rights
 
                                       61
<PAGE>
pursuant to condition (j) above. If InterQual declines by written notice to
terminate the Merger, or if InterQual fails to respond in writing to the
Termination Inquiry within three business days after receipt of the Termination
Inquiry, InterQual subsequently may exercise its termination right under
condition (j) above if and only if the conditions of condition (j) occur during
any 20 consecutive trading days after the date (the "Response Date") which is
the earlier of the date InterQual has responded in writing to the Termination
Inquiry or three days after the date of the Termination Inquiry. However, if the
closing date of the Merger will occur less than 20 consecutive trading days
after the Response Date, InterQual may exercise its termination right under
condition (j) above beginning on the day prior to the closing date of the Merger
(the "Pre-Closing Date") if the conditions of condition (j) have been met during
the 20 consecutive trading days immediately prior to Pre-Closing Date.
 
AFFILIATE/VOTING AGREEMENTS AND AFFILIATE AGREEMENTS
 
    Charles M. Jacobs has entered into an Affiliate/Voting Agreement with Access
Health and InterQual. Under the Affiliate/Voting Agreement, Mr. Jacobs agrees to
(i) restrict sales, dispositions or other transactions reducing his risk of
investment in respect of the shares of InterQual Capital Stock held by him prior
to the Merger and shares of Access Health Common Stock acquired by him in or
after the Merger, subject to a de minimis exception, so as to comply with the
requirements of applicable federal securities laws and to help ensure that the
Merger will be treated as a pooling of interests for accounting and financial
reporting purposes, and (ii) vote in favor of approval of the Merger Agreement
and the Merger. The vote in accordance with the Affiliate/Voting Agreement of
the shares of InterQual Capital Stock subject to such Affiliate/Voting Agreement
will be sufficient to approve the Merger Agreement and the Merger by InterQual
stockholders. In addition, all other executive officers and directors of
InterQual have executed agreements to restrict transfers of shares owned or
acquired by them, subject to the same de minimis exception, so as to comply with
the requirements of applicable federal securities laws and to help ensure that
the Merger will be treated as a pooling of interests for accounting and
financial reporting purposes.
 
    In addition, Access Health's directors and certain officers have executed
Affiliate/Voting Agreements, pursuant to which such persons agree to: (i)
restrict sales, dispositions or other transactions reducing their risk of
investment in respect of the shares of Access Health Common Stock held by them
prior to the Merger and shares of Access Health Common Stock acquired by them
after the Merger, so as to comply with the requirements of federal securities
laws and to help ensure that the Merger will be treated as a pooling of
interests for accounting and financial reporting purposes and (ii) vote in favor
of the issuance of the Access Health Common Stock pursuant to the Merger
Agreement.
 
INDEMNIFICATION OF INTERQUAL OFFICERS AND DIRECTORS
 
    The Merger Agreement provides that commencing with the effectiveness of the
Merger, Access Health shall or shall cause InterQual to provide indemnification,
to the same extent and under similar conditions and procedures as offered to
officers and director of Access Health, to each current officer or director of
InterQual (or any person who shall become an officer or director between the
date of the Merger Agreement and prior to the Effective Time) and each person
who served at the request of InterQual as an officer or director of another
entity. The indemnity obligations of Access Health will survive the consummation
of the Merger for a period of six years and any additional time period beyond
six years as necessary to resolve a claim for indemnification made during the
initial six year period. In the event Access Health merges with another entity
or transfers all or a substantial portion of its properties or assets to any
other person or entity, such successor or assignee must assume such
indemnification obligations of Access Health.

CONSULTING AND EMPLOYEE AGREEMENTS; EMPLOYMENT MATTERS
 
    In connection with the Merger Agreement, an officer and a member of the
InterQual management team will enter into separation and consulting agreements
with Access Health. The separation and consulting agreements generally provide
for separation consideration for termination of the individual's employment with
InterQual, an initial term for consulting services, a fixed consulting fee and a
noncompetition clause which restricts such consultant from engaging in
activities that compete with the businesses of Access Health and InterQual
during a period beginning with the effective date of the separation and
consulting agreement and ending two years after the termination of the
agreement. Three executive officers of InterQual will, and five additional
InterQual officers are expected to enter, into employment agreements with Access
Health in connection with the Merger Agreement.* The employment agreements
generally provide for: a fixed term of employment; an initial base compensation
subject to annual review for increases; eligibility for an incentive bonus of up
to a specified percentage of base compensation; the grant of incentive stock
options under the Access Health Stock Option Plan; and a noncompetition clause
which restricts such employee from engaging in activities that compete with the
businesses of Access Health and InterQual during a period beginning with the
effective date of the employment agreement and ending two years after the
termination of the agreement. In the event that the five additional InterQual
officers do not enter into employment agreements, InterQual is required to have
such officers execute noncompetition agreements containing similar noncompete
provisions as the employment agreements. See "Approval of the Merger and Related
Transactions--Interests of Certain Persons in the Merger."
 
    Access Health has also agreed pursuant to the terms of the Merger Agreement
that for a period of not less than one year following the Effective Time, Access
Health shall maintain InterQual's Marlborough, Massachusetts operations in
Marlborough, Massachusetts and shall not make relocation from the Marlborough,
Massachusetts area a condition of employment for any persons employed by
InterQual.
 
REGISTRATION RIGHTS AGREEMENT
 
    Upon the Effective Time of the Merger, Access Health has agreed to enter
into a Registration Rights Agreement (the "Registration Rights Agreement") which
will provide certain rights with respect to the registration of the shares of
Access Health Common Stock received by Charles M. Jacobs, The Charles M. Jacobs
1998 Family Trust, Susan Weagly Jacobs, The Susan Weagly Jacobs 1998 Family
Trust, Josephine Lamprey, The Josephine Lamprey 1998 Educational Trust, Randolph
W. Seed, and The Randolph W. Seed M.D. 1998 Family Trust (collectively, the
"InterQual Holders") in the Merger. Assuming that the Market Price is at least
equal to $30.3030303 (although there can be no assurance as to the foregoing)
and assuming all outstanding options to purchase InterQual Capital Stock have
been exercised according to their terms, the InterQual Holders will hold
approximately 3,604,200 shares of Access Health Common Stock following the
Merger, and all such shares would be subject to the Registration Rights
Agreement and the shelf registration provisions described below.
 
    Under the Registration Rights Agreement, the InterQual Holders may demand
that Access Health file up to two registration statements under the Securities
Act with respect to the underwritten public offerings of their shares at any
time beginning after the date Access Health has published the combined financial
results of Access Health and InterQual for a period of at least 30 days of
combined operations. Such demand registrations must be for an offering of shares
of Access Health Common Stock having an aggregate value of at least $25 million,
net of underwriting discounts and commissions. This demand registration right is
subject to certain exceptions and limitations including Access Health's right to
delay an offering under certain conditions and the right of the underwriters of
an offering to limit the number of shares included in a registration to up to
50% of the total number of shares to be registered; provided that after the
InterQual Holders have sold an aggregate of two million shares of Access Health
Common Stock pursuant to the Registration Rights Agreement, the underwriters may
limit the number of shares to be registered without regard to a fixed threshold
(the "Underwriters' Cutback"). In addition, if Access Health proposes to
register any of its securities under the Securities Act for its own account or
the account of any
 
                                       63
<PAGE>
of its stockholders, the InterQual holders are entitled to notice of such
proposed registration and the opportunity to include their shares therein (the
"Piggyback Registration Rights"), subject to certain conditions and limitations
including the Underwriters' Cutback.
 
    The registration rights described above (i) will terminate as to any holder
at such time as such holder may sell all his or her shares using the 1% volume
limitation pursuant to Rule 144 under the Securities Act and (ii) may not be
exercisable by a holder at such time as a holder could sell all his or her
shares in a three month period using the average weekly trading volume
limitation pursuant to Rule 144 under the Securities Act, provided that each
holder's Piggyback Registration Rights shall not be suspended until such holder
is able to sell all of his or her shares in a three month period in compliance
with Rule 144 but using 50% of the Rule 144 average weekly trading volume
limitation.
 
    In addition, pursuant to the Merger Agreement, the InterQual Holders will be
granted shelf registration rights permitting the resale pursuant to Rule 415 of
the Securities Act under this proxy and registration statement of up to one
million shares of the Access Health Common Stock held by them, in the open
market at any time beginning as early as the date that combined financial
results for 30 days have been released by Access Health and InterQual, with such
sale to take place through no more than two transactions of at least 250,000
shares per transaction. In connection with the closing of the Merger, the
Company intends to file a registration statement on Form S-3 to register for
resale pursuant to Rule 415 of the Securities Act all such shares that are not
resold under this proxy and registration statement pursuant to the Holders'
shelf registration rights. Under the Registration Rights Agreement, the shelf
registration rights may be suspended under certain conditions upon the request
of Access Health or the managing underwriters of a public offering of Access
Health's Common Stock. Such conditions include (i) the Company engaging in a
business activity or negotiation which is not disclosed in the shelf
registration statement (or the prospectus included therein) which the Company
reasonably believes must be disclosed therein under applicable law and which the
Company desires to keep confidential for business purposes, (ii) the Company
determining that a particular disclosure so determined to be required to be
disclosed therein would be premature or would adversely affect the Company or
its business or prospects, or (iii) that the shelf registration statement can no
longer be used under the existing rules and regulations promulgated under the
Securities Act. The shelf registration rights expire one year after the Closing
Date, or earlier in the event the InterQual Holders holding such rights have
sold in the aggregate at least one million shares of Access Health Common Stock
pursuant to the shelf registration statement, or have sold in the aggregate,
under the Registration Rights Agreement and under any other sale permitted by
the Securities Act, the lesser of two million shares of Access Health Common
Stock or that number of shares of Access Health Common Stock which has resulted
in the InterQual Holders receiving in the aggregate (before deduction of
commissions and other selling expenses) at least $60 million of consideration.
Access Health will pay all registration expenses for any registration pursuant
to the Registration Rights Agreement, but the InterQual Holders included in such
registrations must bear their proportionate share of all selling expenses.
 
   
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
    
 
   
    In the opinion of Ropes & Gray and Wilson Sonsini Goodrich & Rosati,
Professional Corporation (collectively "Counsel") the following discussion sets
forth the material federal income tax consequences of the exchange of shares of
InterQual Capital Stock for Access Health Common Stock pursuant to the Merger.
    
 
    InterQual stockholders should be aware that this discussion does not address
all federal income tax considerations that may be relevant to particular
stockholders of InterQual in light of their particular circumstances, such as
stockholders who are banks, insurance companies, tax-exempt organizations,
dealers in securities, or foreign persons, stockholders who do not hold their
InterQual Capital Stock as capital assets, or stockholders who acquired their
shares in connection with stock option or stock purchase plans or in other
compensatory transactions. In addition, the following discussion does not
address the tax
 
                                       64
<PAGE>
consequences of the Merger under foreign, state or local tax laws or the tax
consequences of transactions effectuated prior or subsequent to or concurrently
with the Merger (whether or not such transactions are in connection with the
Merger), including, without limitation, transactions in which InterQual Capital
Stock is acquired or Access Health Common Stock (including the Escrow Shares) is
disposed of. ACCORDINGLY, INTERQUAL STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE
MERGER IN THEIR PARTICULAR CIRCUMSTANCES.
 
   
    Subject to the limitations, qualifications and assumptions referred to
herein, Counsel is of the opinion that the Merger will qualify as a
"reorganization" within the meaning of Section 368 of the Code (a
"Reorganization") which will result in the following federal income tax
consequences:
    
 
        (a) No gain or loss will be recognized by holders of InterQual Capital
    Stock upon their receipt of Access Health Common Stock solely in exchange
    for InterQual Capital Stock in the Merger.
 
        (b) The aggregate tax basis of the Access Health Common Stock (including
    the Escrow Shares) received by InterQual stockholders in the Merger will be
    the same as the aggregate tax basis of InterQual Capital Stock surrendered
    in exchange therefor less the tax basis, if any, allocated to fractional
    share interests.
 
        (c) The holding period of the Access Health Common Stock (including the
    Escrow Shares) received in the Merger will include the period for which the
    InterQual Capital Stock surrendered in exchange therefor was held.
 
        (d) Cash payments received by holders of InterQual Capital Stock in lieu
    of a fractional share will be treated as if a fractional share of Access
    Health Common Stock had been issued in the Merger and then redeemed by
    Access Health. A stockholder of InterQual receiving such cash will generally
    recognize capital gain or loss upon such payment, equal to the difference
    (if any) between such stockholder's tax basis in the fractional share and
    the amount of cash received.
 
        (e) A stockholder who exercises dissenters' rights with respect to a
    share of InterQual Capital Stock and who receives payment for such stock in
    cash will generally recognize capital gain or loss measured by the
    difference between the stockholder's tax basis in such share and the amount
    of cash received, provided that such payment is neither essentially
    equivalent to a dividend nor has the effect of a distribution of a dividend
    (a "Dividend Equivalent Transaction"). A sale of InterQual Capital Stock
    pursuant to an exercise of dissenters' rights will generally not be a
    Dividend Equivalent Transaction if, as a result of such exercise, the
    stockholder exercising dissenters' rights and all parties related to such
    stockholder own no shares of Access Health Stock (either actually or
    constructively, within the meaning of Section 318 of the Code) after the
    Merger. If, however, a stockholder's sale for cash of InterQual Capital
    Stock pursuant to an exercise of dissenters' rights is a Dividend Equivalent
    Transaction, then such stockholder will generally recognize ordinary income
    for federal income tax purposes in an amount up to the entire amount of cash
    so received.
 
   
        (f) Neither Access Health, Merger Sub nor InterQual will recognize
    material amounts of gain solely as a result of the Merger.
    
 
   
    In connection with this opinion, Counsel has examined the Merger Agreement,
the Registration Statement, and such other documents, records and instruments as
Counsel has deemed necessary or appropriate for purposes of this opinion.
    
 
   
    No opinion is expressed as to any transaction other than as set forth
herein, or as to any other transaction whatsoever, including the Merger, if all
of the transactions described in the Merger Agreement are not consummated in
accordance with the terms of the Merger Agreement (including satisfaction of all
covenants and conditions to the obligations of the parties without amendment or
waiver thereof). To the
    
 
                                       65
<PAGE>
   
extent that any of the representations, warranties, statements and assumptions
material to this opinion and upon which Counsel has relied are not accurate and
complete in all material respects at all relevant times, this opinion would be
adversely affected and should not be relied upon.
    
 
   
    This opinion is based on the Code, existing judicial decisions,
administrative regulations and published rulings. No assurance can be given that
future legislative, judicial or administrative changes or interpretations would
not adversely affect the accuracy of the conclusions stated herein. Counsel
undertakes no responsibility to provide advice regarding any new developments in
the application or interpretation of the federal income tax laws.
    
 
   
    In connection with this opinion Counsel has assumed (without any independent
investigation or review thereof) that:
    
 
   
        a.  Original documents related to the Merger (including signatures
    thereto) are authentic, documents submitted to Tax Counsel as copies conform
    to the original documents, and all such documents have been (or will be by
    the Effective Time) duly and validly executed and delivered where due
    execution and delivery are a prerequisite to the effectiveness thereof;
    
 
   
        b.  All representations, warranties and statements made or agreed to by
    Access Health, Merger Sub and InterQual, their managements, employees,
    officers, directors and stockholders in connection with the Merger,
    including, but not limited to, those set forth in the Merger Agreement
    (including the exhibits thereto) and the tax representation letters
    delivered to Counsel by the management of Access Health, Merger Sub and
    InterQual (the "Tax Representation Letters") are and will be true and
    accurate at all relevant times;
    
 
   
        c.  All covenants contained in the Merger Agreement (including exhibits
    thereto) and the Tax Representation Letters are or will be performed without
    waiver or breach of any material provision thereof;
    
 
   
        d.  Each of Access Health, InterQual and Merger Sub will comply with all
    reporting obligations with respect to the Merger required under the Code and
    the Treasury regulations promulgated thereunder and will treat the Merger as
    a Reorganization;
    
 
   
        e.  Any representation or statement made "to the best of knowledge" or
    similarly qualified is and will continue to be correct without such
    qualification; and
    
 
   
        f.  The Merger will be effective as a merger under the applicable laws
    of Delaware.
    
 
   
    Because this opinion is being delivered prior to the Effective Time of the
Merger, it must be considered prospective and dependent on future events. There
can be no assurance that changes in the law will not take place which could
affect the federal income tax consequences of the Reorganization.
    
 
   
    No ruling has been or will be obtained from the Internal Revenue Service
(the "IRS") in connection with the Merger. InterQual stockholders should be
aware that this opinion only represents Counsel's best judgment as to the
federal income tax consequences of the Merger and does not bind the IRS or any
court of law, tribunal, administrative agency or other governmental body and
that the IRS is not precluded from successfully asserting a contrary opinion.
    
 
    A successful IRS challenge to the Reorganization status of the Merger would
result in InterQual stockholders recognizing taxable capital gain or loss with
respect to each share of InterQual Capital Stock surrendered equal to the
difference between the stockholder's tax basis in such share and the fair market
value, as of the Effective Time, of the Access Health Common Stock received in
exchange therefor. In such event, a stockholder's aggregate basis in the Access
Health Common Stock so received would equal its fair market value as of the
Effective Time and the holding period for such stock would begin the day after
the Effective Time.
 
                                       66
<PAGE>
GOVERNMENTAL AND REGULATORY APPROVALS
 
    Other than compliance with the federal securities laws and applicable
securities laws of the various states, Access Health and InterQual are aware of
no governmental or regulatory approvals required for consummation of the Merger.
Access Health and InterQual have already complied with the requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.
 
ACCOUNTING TREATMENT
 
    The Merger is intended to qualify as a pooling of interests for financial
reporting purposes in accordance with generally accepted accounting principles.
Consummation of the Merger is conditioned upon (i) Access Health receiving a
letter from Arthur Andersen LLP, Access Health's independent auditors, regarding
such firm's concurrence with Access Health management's conclusions as to the
appropriateness of pooling-of-interests accounting for the Merger under
Accounting Principles Board Opinion No. 16, if consummated in accordance with
the Merger Agreement and (ii) Alexander, Aronson, Finning & Co., P.C. providing
a letter, satisfactory in form and substance to Access Health, regarding the
appropriateness of pooling-of-interests accounting for a transaction involving
InterQual.
 
DELAWARE APPRAISAL RIGHTS
 
    Holders of InterQual Class A Common Stock who do not vote by written consent
in favor of the Merger and holders of InterQual Class B Common Stock may, under
certain circumstances and by following the procedure prescribed by the DGCL,
exercise appraisal rights and receive cash for their shares of InterQual Capital
Stock. The stockholders exercising appraisal rights under the DGCL must follow
the appropriate procedures under the DGCL or suffer the termination or waiver of
such rights.
 
    If a holder of InterQual Capital Stock exercises appraisal rights in
connection with the Merger under Section 262 of the DGCL ("Section 262"), any
shares of InterQual Capital Stock in respect of which such rights have been
exercised and perfected will not be converted into Access Health Common Stock
but instead will be converted into the right to receive such consideration as
may be determined by the Delaware Court of Chancery (the "Court") to be due with
respect to such shares pursuant to the laws of the State of Delaware.
 
    The following summary of the provisions of Section 262 is not intended to be
a complete statement of such provisions and is qualified in its entirety by
reference to the full text of Section 262, a copy of which is attached to this
Proxy Statement/Prospectus and Notice and Consent Solicitation Statement as
Annex D and incorporated herein by reference.
 
    Holders of shares of InterQual Capital Stock who object to the Merger and
who follow the procedures in Section 262 will be entitled to have their shares
of InterQual Capital Stock appraised by the Court and to receive payment of the
"fair value" of such shares as of the Effective Time of the Merger.
 
    In the event that the holders of the InterQual Class A Common Stock approve
the Merger Agreement by written consent in accordance with the DGCL, either
before the Effective Time or within ten days thereafter, Access Health and
InterQual must each notify each holder of InterQual Class A Common Stock who did
not so consent in writing and each holder of InterQual Class B Common Stock who
elects such appraisal rights at such Effective Time and that appraisal rights
are available for any or all of the shares of InterQual Capital Stock held by
such stockholder. A stockholder of InterQual electing to exercise appraisal
rights must, within 20 days of the date of mailing of such notice, perfect his,
her or its appraisal rights by demanding in writing from InterQual the appraisal
of his, her or its shares of InterQual Capital Stock, as provided in Section
262. A holder who elects to exercise appraisal rights should mail or deliver
his, her or its written demand to InterQual at 293 Boston Post Road West, Suite
180, Marlborough, Massachusetts 01752. The demand should specify the holder's
name and mailing address, the number of shares of InterQual Capital Stock owned
and that such holder is demanding appraisal of his, her or its
 
                                       67
<PAGE>
shares. Only a holder of record of shares of InterQual Capital Stock (or his,
her or its duly appointed representative) is entitled to assert appraisal rights
for the shares registered in that holder's name.
 
    Within 120 days after the Effective Time of the Merger, any holder of
InterQual Class A Common Stock who has made a valid written demand and who has
not voted in favor of approval and adoption of the Merger Agreement or any
holder of InterQual Class B Common Stock who has made a valid written demand and
who has not exchanged his shares may (i) file a petition in the Court demanding
a determination of the value of shares of InterQual Capital Stock, and (ii) upon
written request, receive from InterQual a statement setting forth the aggregate
number of shares of InterQual Capital Stock not voted in favor of approval and
adoption of the Merger Agreement and approval of the Merger and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares. Such statement must be mailed within ten days after the
written request therefor has been received by InterQual.
 
    If a petition for an appraisal is timely filed, at a hearing on such
petition, the Court is required to determine the holders of Dissenting Shares
entitled to appraisal rights and to determine the "fair value" of the Dissenting
Shares exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to be
paid upon the value of the Dissenting Shares. In determining such "fair value",
the Court is required to take into account all relevant factors, and in
determining the fair value of interest, the Court may consider the rate of
interest which InterQual would have had to pay to borrow money during the
pendency of the proceeding. Upon application by a stockholder, the Court may
also order that all or a portion of the expenses incurred by any stockholder in
connection with the appraisal proceeding, 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 the shares of
InterQual Capital Stock entitled to appraisal.
 
    Any holder of Dissenting Shares who has duly demanded an appraisal under
Section 262 will not, after the Effective Time of the Merger, be entitled to
vote the shares subject to such demand for any purpose or be entitled to the
payment of dividends or other distributions on such Dissenting Shares (except
dividends or other distributions payable to stockholders of record as of a date
prior to the Effective Time of the Merger).
 
    If any holder of shares of InterQual Capital Stock who demands appraisal
under Section 262 effectively withdraws or loses, his, her or its right to
appraisal, the shares of such holder will be converted into a right to receive
that number of shares of Access Health Common Stock as is determined in
accordance with the Merger Agreement. A holder will effectively lose his right
to appraisal if he, she or it votes in favor of approval and adoption of the
Merger Agreement, or if no petition for appraisal is filed within 120 days after
the Effective Time of the Merger, or if the holder delivers to InterQual a
written withdrawal of such holder's demand for an appraisal and an acceptance of
the Merger, except that any such attempt to withdraw made more than 60 days
after the Effective Time of the Merger requires the written approval of
InterQual. A holder of stock represented by certificates may also lose his, her
or its right to appraisal if he, she or it fails to comply with the Court's
direction to submit such certificates of stock to the Register in Chancery for
notation thereon of the pendency of the appraisal proceedings.

               PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
    The following unaudited pro forma condensed combined financial statements,
including the notes thereto, are qualified in their entirety by reference to and
should be read in conjunction with, the historical consolidated financial
statements of Access Health and InterQual, including the notes thereto, included
or incorporated by reference herein.
 
    The unaudited pro forma condensed financial statements assume a business
combination between Access Health and InterQual accounted for on a
pooling-of-interests basis and are based on each company's respective historical
consolidated financial statements and notes thereto, which are included or
incorporated by reference herein. The unaudited pro forma condensed combined
balance sheet combines Access Health's unaudited consolidated condensed balance
sheet as of March 31, 1998 with InterQual's unaudited condensed balance sheet as
of March 31, 1998, giving effect to the Merger as if it had occurred on March
31, 1998. The unaudited pro forma combined condensed statements of operations
combine Access Health's historical results for the years ended September 30,
1995, 1996 and 1997 and the six months ended March 31, 1997 and 1998 with
InterQual's historical results for the years ended December 31, 1995, 1996 and
1997 and the six months ended March 31, 1997 and 1998, respectively, giving
effect to the Merger as if it had occurred at the beginning of the earliest
period presented.
 
    The pro forma information is presented for illustrative purposes only and is
not necessarily indicative of the operating results or financial position that
would have occurred if the Merger had been consummated at the beginning of the
earliest period presented, or at March 31, 1998, as appropriate, nor is it
necessarily indicative of future operating results or financial position.

    Access Health and InterQual each adopted Statement of Financial Accounting
Standards No. 128 "Earnings per Share" ("SFAS 128"), which was required to be
adopted on December 15, 1997. This statement establishes standards for computing
and presenting basic and diluted earnings per share. Under this statement, basic
earnings or loss per share is computed by dividing the net earnings or loss by
the weighted average number of shares of common stock outstanding. Diluted
earnings or loss per share is determined by dividing the net earnings or loss by
the sum of (1) the weighted average number of common shares outstanding, (2) if
not anti-dilutive, the number of shares of convertible preferred stock as if
converted upon issuance, and (3) if not anti-dilutive, the effect of outstanding
stock options determined utilizing the treasury stock method.

OVERVIEW
 
    Access Health is a leading provider of care management products and services
to the health care industry. Access Health provides its services primarily
through four telephonic care centers, which are staffed by registered nurses and
other health care professionals. Access Health's primary clients include HMOs,
PPOs, indemnity insurers, integrated delivery systems, government agencies,
self-insured employers and physician groups. Access Health's objective is to
measurably improve the delivery of health care through dynamically integrated
programs that help individuals effectively manage their health needs. Its
products and services are designed to help reform an inefficient health care
system in ways that benefit health care payors, providers and individuals.
 
CORPORATE HISTORY
 
    Access Health was founded in 1987 and until 1993 primarily provided consumer
health care information products and services designed to help hospitals and
other health care providers market their services. Beginning in 1993, Access
Health changed its focus to developing, marketing and delivering personal health
management products and services to health plans and payors, which were
primarily designed as a value added member benefit to help attract and retain
members. At the same time, Access Health altered its business model to price its
products and services predominantly on a recurring per-member per-month fee
basis rather than on a non-recurring basis. Access Health enjoyed significant
growth of its personal health management business through mid-1996, at which
point customer demand for care management products, which provided demonstrable
cost savings, began to intensify. At the time, health care service providers
were experiencing increased price competition and rising medical costs,
resulting in unprecedented high medical loss ratios and lower profitability. In
November 1996, Access Health merged with Informed Access, a developer of
leading-edge clinical assessment tools and care management programs. With this
merger, Access Health significantly expanded its suite of care management
products and substantially enhanced its ability to provide its customers a
demonstrable return on investment. Also in November 1996, Access Health acquired
CRS, which develops health information and patient education software programs.
Access Health's care management business has grown dramatically; the number of
enrolled members has increased to approximately 25 million in February 1998 from
over 14 million at the end of fiscal 1996.
 
INDUSTRY BACKGROUND
 
    The rate of health care spending increases in the United States continues to
exceed gross domestic product ("GDP") growth. The Congressional Budget Office
expects national health expenditures to reach 13.7% of GDP or slightly more than
$1.1 trillion in 1997. Containment of health care costs has become a national
priority. As a result, cost-conscious managed health care programs have
increasingly influenced the health care system. These managed care programs have
traditionally reduced the cost of health care by restricting access to care
(through financial management techniques such as pre-authorization, pre-
 
                                       76
<PAGE>
certification, and concurrent and retrospective review programs to manage
members' use), pushing cost risk down to providers and reducing administrative
expenses. While these techniques have been moderately successful in controlling
costs, there is increasing evidence that their returns are diminishing. Because
the approach to managing care has largely been to restrict supply, a number of
inefficiencies continue to persist, which have contributed to escalating health
care costs. These include:
 
    - LACK OF ACCESS AND INAPPROPRIATE USE OF HEALTH CARE RESOURCES. Individuals
      who lack timely access to health care and to reliable health care
      information may delay needed treatment, self-treat inappropriately or seek
      unnecessary care, all of which can lead to poor health outcomes and higher
      costs. For example, studies indicate that up to 55% of all emergency room
      visits may be inappropriate.
 
    - LACK OF PREVENTIVE CARE AND EARLY INTERVENTION. Appropriate preventive
      care and early intervention can dramatically influence health and well
      being and is cost-effective. Preventive care and timely intervention both
      depend on an individual's access to information.
 
    - INSUFFICIENT CHRONIC CONDITION MANAGEMENT. In managing chronic conditions
      today, there exists a significant gap between nationally accepted disease
      management guidelines and the actual day-to-day patient practices. This
      gap results in less than optimal patient care and unnecessary medical
      costs and other related costs, including missed work days. Approximately
      70% of overall health care costs incurred today are chronic-condition
      related.
 
    Care management programs have been developed in response to these problems.
These programs generally include telephone-based health counseling services to
help individuals optimize their use of the health care system. These services
increase members' involvement in managing their own health and empower them to
make better-informed decisions. The information they receive provides member the
opportunity to obtain proper care and to avoid unnecessary care, reduce health
care costs, improve health outcomes and increase satisfaction with their health
care plans.
 
STRATEGY
 
    Access Health seeks to measurably improve the quality and costs of care
people receive by becoming an integral part of health care delivery. Access
Health's goal is to further integrate its services with its customers' delivery
of care, resulting in increased utilization of Access Health's products and
services across an increasing number of members. It seeks to accomplish these
goals through the following business strategies:
 
    - BUILD ENROLLMENT THROUGH DEMONSTRATED RESULTS. Access Health seeks to
      continue building market share through rapid enrollment growth. Access
      Health is focused on building enrollment through increased member
      penetration within existing accounts and contracting with new client
      sponsors. Access Health believes that its sales and marketing strategy
      (see "Sales, Marketing and Support") coupled with its ability to provide a
      compelling return on investment for customers in the form of reduced
      health care costs, increased member satisfaction and improved quality of
      care will be the primary drivers for continued rapid enrollment growth.*
 
    - INCREASE REVENUE PER MEMBER THROUGH NEW PRODUCTS AND SERVICES. Access
      Health's average revenue per member derived from its care management
      products today is a small fraction of the national averages spent
      per-member per-month for health care services. Because Access Health's
      care management products are utilization-based, Access Health seeks to
      significantly expand the average revenue per member by increasing adoption
      of its higher utilization, advanced care management and condition
      management products.
 
    - EXTEND CAPABILITIES THROUGH STRATEGIC PARTNERSHIPS. In addition to Access
      Health's internal product development and process improvement efforts,
      Access Health continues to actively evaluate
 
                                       77
<PAGE>
      possible new business models and strategic relationships and acquisitions
      to further expand its product capabilities and membership base.
 
PRODUCTS AND SERVICES
 
    The Personal Health Advisor-Registered Trademark- ("PHA") product line
features a core set of care management products and services that provide
members with consistent clinical assessment and guidance about the use of health
care services for both acute and chronic conditions and to help guide these
individuals to the most appropriate point of care within a managed care network.
Managed care providers and insurers use PHA to facilitate easier access to the
plan network by members, reduce operating costs by reducing inefficient use of
network resources and improve the quality of care for plan members. PHA products
are used by MCOs in a variety of applications including use as the primary
"gateway" to a plan network, as an emergency room pre-certification tool, a
health care management tool for individuals with chronic conditions, or solely
as a health care information service for plan members. PHA also provides
extensive reporting, which enables managed care organizations to more
efficiently configure their service delivery network.
 
    The foundation of the PHA product line is Access Health's proprietary
Clinical Decision Architecture ("CDA"). The CDA provides the structure
surrounding Access Health's patented process for the consistent assessment of a
patient's condition, the arrival at an appropriate care recommendation, and the
linking of a patient with a provider who has the requisite clinical expertise to
care for the condition or symptom set identified. CDA primarily utilizes four
information databases, including a database of over 550 proprietary risk-sorting
clinical algorithms, a detailed provider information database, a health care
information database that includes extensive self-care instructions and a
database of health plan members and rules pertinent to the plan structure.
 
    The PHA care management programs are designed to address the needs for both
acute and chronic care management. The PHA programs offer customers a flexible
solution, allowing virtually any combination of product components to meet a
customer's unique needs. Each of the products can also be offered in a
stand-alone environment. Most importantly, when a sponsor chooses multiple
products to offer its members, the components are integrated seamlessly using
the CDA's common delivery platform and information warehouse. In doing so, a
person-based, custom care management program is created for each member that is
delivered through a single point of access.
 
ACUTE CARE MANAGEMENT PROGRAMS
 
    FIRSTHELP-TM-.  The FirstHelp-TM- patient assessment system is the acute
care cornerstone for all of the PHA services. The FirstHelp-TM- patient
assessment system is a clinically advanced, proprietary process for assessing a
caller's symptoms, integrating a provider's recommendations and providing
consistent care recommendations. The FirstHelp-TM- system provides the basis for
Access Health's 24-hour-a-day telephone triage services provided for health plan
members, and assists health plans and providers in reducing emergency room and
physician office visits for conditions which can safely be treated in less
intensive settings. A key component of Access Health's CDA, the FirstHelp-TM-
system consists of over 550 risk-sorting clinical algorithms, including modules
for pediatrics, adults, women, seniors, and mental health. The algorithms employ
a series of predetermined questions in a set order--a proprietary technique
designed to mimic physician assessment. With this system, nurses can effectively
guide callers to the most appropriate level of care. High physician concordance
(more than 93%) with FirstHelp-TM- assessment recommendations means that advice
given in an acute episode will likely mirror that of the patient's own
physician. When a condition will not benefit from a provider visit, callers are
given self-care instructions and are offered a follow-up call to check progress.
Physicians benefit by receiving fewer after-hours calls and handling more
appropriate office visits.
 
                                       78
<PAGE>
    ER ACCESS-SM-.  The ER Access-SM- program is designed to measurably reduce
unnecessary ER utilization and associated costs while concurrently educating
members and improving member satisfaction. The program utilizes the
FirstHelp-TM- patient assessment algorithms, which allow Access Health's care
center nurses to assess the urgency of a patient's need for medical care and the
level and timing of the intervention needed. Care center nurses are able to
perform symptomatic assessments on members who were planning to go to the ER,
and in many cases will recommend a lower and less costly level of care. ER
Access-SM- offers the added benefit of relieving the primary care physician from
direct involvement in approving or denying emergency care.
 
    OPEN ACCESS.  For health plans looking to offer alternatives to the primary
care "gatekeeper" referral process, Access Health has developed an "intelligent
gateway" to care. With its Open Access program in place and available to members
24 hours a day, 7 days a week, Access Health's nurses can assess patient needs
and match patients with appropriate providers based on health plan rules.
Through the FirstHelp-TM- patient assessment algorithms and the capabilities of
the CDA, members are guided to providers who have indicated a specific focus on
the clinical conditions identified. Open Access provides an effective means of
matching patient needs with an appropriate provider when a specialty referral
can be predicted.
 
    PROVIDER PROFILER-SM-.  Provider Profiler-SM- is a PC-based software tool
designed to collect extensive, important information about a provider's
background and current practice for use in patient-provider matching. Once it is
determined that a caller's symptoms require a provider evaluation, this
information is designed to be linked to a provider who can appropriately manage
the symptom set, who is located in the caller's area, and whose office hours
accommodate the urgency of the evaluation. The system is also designed to
support provider credentialing activities in accordance with NCQA standards, and
can function as an electronic provider directory to help members identify and
select a physician quickly.
 
DISEASE AND CONDITION MANAGEMENT PROGRAMS
 
    ASTHMA CARE MANAGEMENT AND DIABETES CARE MANAGEMENT PROGRAMS.  Access Health
has developed disease management programs designed to proactively assist
patients with the longitudinal management of chronic conditions in accordance
with physician prescribed regimens. The goals of the programs are to improve the
quality of life for patients with chronic conditions by reducing the risk of
complications and to help contain health care costs by reducing the need for
extensive use of health care services. Patients enrolled in the disease
management program receive regular calls from specialized Access Health nurses
who monitor the patient's condition and the patient's compliance with a
treatment regimen. The enrolled patients also receive information to educate
them on how to effectively manage their chronic condition.
 
    9 MONTHS & BEYOND-SM- MATERNITY MANAGEMENT PROGRAM.  9 Months & Beyond-SM-
is the PHA program for expectant mothers designed to support physician and
health plan goals using comprehensive telephone-based maternal education,
monitoring and counseling throughout pregnancy and after delivery. The program
regularly monitors each member's level of risk for experiencing preterm labor,
delivering a low birth weight baby, and/or delivering via cesarean section. This
information drives an intervention program that includes both general education
and personalized counseling aimed at reducing the member's risk for any of these
outcomes as well as the costs usually associated with these outcomes.
 
    FIRST WARNING.  First Warning is a case management alert system designed to
alert a health plan's internal case management function whenever a caller is
identified as having a certain high risk or potentially high-cost condition.
Examples include the presence or diagnosis of a chronic condition such as
arthritis, diabetes, or low back pain or the presence of symptoms of early
labor. The First Warning system is designed as an adjunct to other PHA
components; however, it also serves as a mechanism for enrolling eligible
patients in one or more of the PHA disease/condition management programs.
 
                                       79

ADDITIONAL PRODUCTS AND SERVICES
 
    FIRST WELCOME-SM-.  Access Health is introducing a new member contact
program, called First Welcome-SM-, to assist managed care organizations in
introducing new members to a health plan, selecting primary care providers for
them, and conducting a preliminary evaluation of these members' medical
conditions and potential health care needs. The program is designed to identify
and initiate appropriate interventions within the structure of the plan,
including the ability to enroll members in Access Health's disease/condition
management programs.
 
    RIGHT CALL MEMBER COMMUNICATIONS SERVICES.  Right Call member communication
services are tailored to meet specific sponsor needs. These services consist of
the development, execution and fulfillment of membership enrollment materials,
such as membership kits, newsletters and other mailings, on-going communication
programs designed to facilitate appropriate use of PHA programs, and fulfillment
of member requests for literature for specific health care topics.
 
    AUDIOHEALTH LIBRARY-REGISTERED TRADEMARK-.  Customers have access via
touch-tone or rotary telephone to the PHA audiotext self-care library. The
AudioHealth Library-Registered Trademark- is a sophisticated database of
pre-recorded information on over 500 health topics, including information on
specific conditions and self-care and prevention information. After reviewing
information in the AudioHealth Library-Registered Trademark-, the customer can
elect to speak directly with an Access Health nurse.
 
    PREVENTIVE CARE REMINDER SYSTEM.  Access Health developed the Preventive
Care Reminder System in response to the growing needs of its clients to meet
NCQA preventive care standards, to ensure favorable performance in satisfying
Health Plan Employer Data and Information Set measures of quality, and to
improve compliance with basic preventive care recommendations of national
organizations including the U.S. Preventive Services Task Force and the American
Academy of Pediatrics. The service is provided as an adjunct to other PHA
services as a delivery system for personalized reminders to members about
recommended preventive measures, such as mammograms and pap smears. The
Preventive Care Reminder System improves health care by boosting compliance with
preventive care standards.
 
    PHA ONLINE.  PHA Online is an interactive and proactive service that offers
PHA members highly personalized health information and online activities based
on their needs and interests. It can be easily configured to work in conjunction
with a health plan's objectives--including member recruitment, development and
services, and open enrollment campaigns. The PHA Online service is anchored by
an Internet website that encourages members to continually interact with the
service.
 
LICENSING AND SUPPORT SERVICES
 
    Access Health also licenses PHA acute care products to customers who offer
the services through their own care centers. These products are licensed with a
recurring license revenue stream tied to utilization and/or the size of the
population served. Access Health also offers other products under a variety of
licensing formulas. These other products are listed below.
 
    ACCESS CARE MANAGEMENT SYSTEM-SM-.  The Access Care Management System-SM-
("ACMS"), introduced in 1994, is utilized by those organizations seeking to
provide in-house care management services. ACMS is an integrated package of
software, clinical guidelines and care management functions that enables
hospitals, physician groups, integrated health care delivery systems and health
plans to offer care management services directly to patients and member groups
through the sponsoring organization's own telephone call center. ACMS customers
pay Access Health on a per-member per-month basis and in return receive
technical support and software and clinical database upgrades.
 
    ASK-A-NURSE-REGISTERED TRADEMARK-.  The ASK-A-NURSE-Registered Trademark-
family of products is licensed to hospitals and other health care systems,
enabling them to provide health care information and referral services. The
 
                                       80
<PAGE>
ASK-A-NURSE-Registered Trademark- product family was introduced in 1987 and is
currently licensed to more than 50 clients representing over 130 participating
hospitals in the United States.
 
    CANCER HELPLINK-REGISTERED TRADEMARK- SYSTEM.  The Cancer
HELPLINK-Registered Trademark- product is a specialized information and referral
system staffed by Access Health nurses experienced in cancer care and trained in
the extensive information needs of cancer patients, their families and others
concerned about cancer. The Cancer HELPLINK-Registered Trademark- system,
introduced in 1989, provides needed information to patients diagnosed with
cancer and refers callers who have cancer symptoms to appropriate physicians and
diagnostic and treatment services. Access Health's cancer products are currently
licensed to more than 17 clients representing over 20 hospitals.
 
    HEALTHSELECT.  Access Health sells and supports the HealthSelect software
products, which are designed to support health care information and referral
programs. These products enable participating hospitals to match individuals'
health care needs with physicians and hospital services and to manage referral,
medical information and reporting functions. In addition, these software
products allow hospitals to manage membership programs, scripted outbound call
programs and other database management activities. More than 120 hospitals have
licensed HealthSelect software.
 
PRODUCT DEVELOPMENT
 
    Access Health's growth and future success largely depend upon its ability to
develop new products for the health care industry and to continue to enhance its
existing care management products. Additional care management applications that
are in various stages of development and planned for general release in 1998
include disease management programs for cardiac conditions, pulmonary conditions
in addition to asthma, hypertension, and depression. Also in the design and
development phase are programs to assist health plan customers in utilization
review and utilization management, as well as a program to assist customers in
identifying workers' compensation episodes. General and ongoing development
initiatives include:
 
    - ALGORITHMS. Access Health regularly evaluates and enhances its
      FirstHelp-TM- clinical algorithms based upon advances in medicine and upon
      its own internal continuous quality improvement initiatives.
 
    - TECHNOLOGY INFRASTRUCTURE. Access Health continues to enhance its
      infrastructure by installing new hardware and software systems to improve
      capability, ease of use and scalability. Access Health is in the process
      of completing a common technology platform whereby all care centers will
      use a common hardware, software and voice technology platform. This
      integrated platform is scheduled to be rolled out to its existing
      customers during calendar 1998.
 
    - CUSTOMIZED PRODUCTS. Access Health customizes products for specific market
      segments such as those with special literacy or foreign language needs.
 
    - ELECTRONIC DELIVERY SYSTEMS. Access Health has developed and continues to
      expand its capabilities to use on-line communications and other electronic
      media to deliver Access Health's products and services.
 
PRINCIPAL CUSTOMERS
 
    Access Health markets its products and services to MCOs, government
agencies, self-insured employers, hospitals, integrated hospital organizations,
physician groups, and independent physician associations.
 
    Enrolled members of Access Health are those for whom Access Health receives
revenues. As of February 1998, Access Health had contracts with customers
representing approximately 25 million members enrolled in PHA. Also as of this
date, Access Health had commitments for approximately 3 million new members to
be enrolled in its care management programs in future quarters. Some of the
 
                                       81
<PAGE>
commitments included in this backlog figure are subject to final contract
execution. Certain of Access Health's contracts specify a guaranteed enrollment
rate for members and Access Health receives revenues for such amounts even if
the customer has not yet identified all the particular members. After initial
terms of approximately one to four years, contracts generally can be terminated
upon 60 to 360 days notice. No single client accounted for more than 10% of
Access Health's annual revenues in fiscal 1997.
 
    Access Health's ACMS, ASK-A-NURSE-Registered Trademark- and Cancer
HELPLINK-Registered Trademark- products are currently licensed to more than 80
clients. Examples of Access Health's principal customers for these product lines
include Florida Hospital in Orlando, Riverside Health Systems and Emory
University Systems of Health Care in Atlanta.
 
SALES, MARKETING AND SUPPORT
 
    Access Health sells its products and services exclusively through its direct
sales and account management force. Access Health employs a combined sales and
account team strategy, dedicating two high level sales representatives with
two-to-three account managers to each of six distinct national geographic
regions. These teams are incented to add new clients and grow new business with
existing accounts through the addition of new members, higher utilization of
existing products and adoption of new products. Access Health is primarily
focused on selling Access Health's products and services to MCOs, self-insured
employers, commercial insurers, government entities, and hospitals and health
care systems.
 
    Access Health also employs a client services department to assist in its
on-going relationships with clients through the use of client service teams that
include implementation, clinical and technical support representatives. These
teams work closely with new and existing clients to implement custom tailored
programs, coordinate member communication programs, ensure client satisfaction,
and evaluate program effectiveness.
 
    Access Health's marketing strategy also includes building brand awareness
and brand identity for its Personal Health Advisor,
ASK-A-NURSE-Registered Trademark- and Cancer HELPLINK-Registered Trademark-
products.
 
COMPETITION
 
    The market for Access Health's products and services is highly competitive.
Access Health's competition includes independent companies as well as divisions
of large MCOs. Access Health also faces competition from potential customers who
may elect to develop their own personal care management solutions, and Access
Health expects to face competition from new entrants to the market. Access
Health believes that it competes favorably on the basis of price and value,
operational capabilities, clinical content of its proprietary clinical
algorithms, ability to rapidly enroll new members and performance with respect
to cost savings, superior outcomes and member satisfaction. To the extent Access
Health offers new products or services or offers its existing products and
services in new markets, it expects to face increased competition from
competitors which may have substantially greater financial, marketing or
technical resources than Access Health, as well as from industry consolidations
that create larger competitors offering new products and services.
 
GOVERNMENT REGULATION
 
    The health care industry is subject to extensive and evolving government
regulation at both the Federal and state levels relating to many aspects of
Access Health's and its clients' businesses, including the provision of health
care services, teleservicing, health care referral programs, health maintenance
organizations and other similar plans. These statutes and regulations in many
cases predate the development of telephone-based health care information and
other interstate transmission and communication of medical information and
services. The language of certain of these statutes and regulations governing
the provision of health care services, including, without limitation, the
practice of nursing and the practice of medicine, could be construed by
regulatory authorities to apply to certain of Access Health's teleservicing
 
                                       82
<PAGE>
activities, which use California, Illinois, Arizona and Colorado registered
nurses to provide care management services such as nursing assessments and
information regarding appropriate sources of care and treatment time frames.
These statutes and regulations could also apply to certain activities of Access
Health's health service customers when operating Access Health's programs. In
addition, the language of the statutes and regulations governing health
maintenance organizations and other plans that provide or arrange for the
provision of health care services for a prepaid or periodic charge could be
construed by regulatory authorities to apply to certain activities of Access
Health that are provided on a per-member per-month basis. While some states have
indicated their intention to interpret their statutes to require licensure for
out-of-state providers, most states have not addressed this issue by regulation
or state legislation. However, if regulators seek to apply any of the foregoing
statutory and regulatory requirements to Access Health or to others operating in
a manner substantially similar to Access Health, then Access Health, its
employees and/or its clients could be required to obtain additional licenses or
registrations, to modify or curtail the operation of Access Health's programs,
to modify the method of payment for Access Health's programs, or to pay fines or
incur other penalties.
 
    The payment of remuneration to induce the referral of health care business
was the subject of increasing governmental and regulatory focus in recent past
years. Section 1128B(b) of the Social Security Act (sometimes referred to as the
"Federal anti-kickback statute") provides criminal and civil money penalties for
individuals or entities that knowingly and willfully offer, pay, solicit or
receive remuneration in order to induce referrals for items or services for
which payment may be made under the Medicare and Medicaid programs and certain
other government-funded programs. The Social Security Act also provides
authority to the Office of the Inspector General, through civil proceedings, to
impose penalties and to exclude an individual or entity from participation in
the Medicare and state health programs if it is determined any such party has
violated Section 1128B(b) of the Social Security Act. Regulations have been
promulgated specifying certain payment practices, which will not be subject to
criminal prosecution, civil penalties nor exclusions. These regulations,
commonly referred to as the "safe harbor" regulations, do not expand the scope
of the Federal anti-kickback statute, and the fact that a business arrangement
does not fit within a safe harbor does not necessarily mean the business
arrangement violates the Federal anti-kickback statute. Some of Access Health's
programs involve payment for referral services and meet most, but not all, of
the requirements of the safe harbor for referral services. In addition, a number
of states in which Access Health operates have anti-kickback statutes similar to
the Federal statute, as well as statutory and regulatory requirements governing
referral agencies and regulating franchising and business opportunity ventures.
The Federal government and a number of states also have enacted statutes which
contain outright prohibitions on referrals for specified services which are made
by referring providers who have an ownership interest in, or compensation
arrangement with, the entity to which the referral is made. If Access Health or
the use of its products and services were to be found in violation of such
statutes, Access Health or its clients could be required to modify or curtail
the operation of Access Health's programs, or to pay fines or incur other
penalties, and Access Health's clients could be excluded from participation in
federal health care programs, including Medicare and Medicaid programs, and
could be precluded from charging fees and obtaining reimbursement for specified
services.
 
    There can be no assurance that Access Health or the use of its products and
services will not be subject to review or challenge by government regulators
under any of the foregoing statutes and regulations that apply to health care
services and products. In addition, additional laws and regulations could be
enacted in the future that would regulate Access Health or the use of its
products and services. Any government investigative or enforcement actions with
respect to Access Health or the use of its products or services could generate
adverse publicity irrespective of the final outcome, and could have a material
adverse effect on Access Health.

RISK MANAGEMENT
 
    In recent years, participants in the health care industry, including
physicians, nurses and other health care professionals, have been subject to an
increasing number of lawsuits alleging malpractice, product liability and
related legal theories, many of which involve large claims and significant
defense costs. Due to the nature of its business, Access Health could become
involved in litigation regarding the telephone information given by its
registered nurses or those of its licensees with the risk of adverse publicity,
significant defense costs and substantial damage awards. Access Health has
established policies and procedures that limit the information provided by its
registered nurses to that contained in its algorithms and protocols and in other
approved reference sources. In connection with its teleservices operations,
Access Health has a quality assurance program that includes real-time audits of
calls and post call reviews to monitor compliance with established policies and
procedures. Generally, clients review and approve Access Health's algorithms,
protocols and guidelines prior to program implementation and do not modify them
without medical approval. To date, Access Health has not been the subject of any
claim involving either its clinical assessment systems, the operation of its
teleservicing centers or the operation by hospital clients of on-site care
centers. However, there can be no assurance that claims will not be brought
against Access Health. Even if such claims ultimately prove to be without merit,
defending against them can be time consuming and expensive, and any adverse
publicity associated with such claims could have a material adverse effect on
Access Health.
 
    While Access Health maintains professional liability insurance, there can be
no assurance that claims in excess of Access Health's insurance coverage will
not arise or that all claims would be covered by such insurance. In addition,
although Access Health has not experienced difficulty in obtaining insurance
coverage in the past, Access Health may seek increased insurance coverage as its
business grows. There can be no assurance that Access Health has appropriate or
sufficient coverage under its existing insurance plans or that Access Health
will be able to obtain appropriate or sufficient amounts of insurance in the
future to address the foregoing risks on terms that are commercially reasonable.
 
INTELLECTUAL PROPERTY
 
    Access Health regards its software, CDA, algorithms, clinical nursing
assessment protocols and marketing and program operation materials as
proprietary and takes action to protect its intellectual property with patents,
copyrights, trademarks, trade secret laws and restrictions on disclosure,
copying and transferring title. Access Health has been issued patents in the
United States that cover a number of inventions, including the structure, use
and process of its CDA and clinical database and certain capabilities of the
provider profiler product. There can be no assurance that competitors, some of
which have substantial resources and have made substantial investments in
competing technologies, will not seek to apply for and obtain patents that will
prevent, limit or interfere with Access Health's ability to make, use or sell
its products either in the United States or in international markets. Litigation
or regulatory proceedings, which could result in substantial cost and
uncertainty to Access Health may also be necessary to enforce Access Health's
intellectual property rights, including patents, or to determine the scope and
validity of other parties' proprietary rights. It is also possible that Access
Health may need to acquire licenses to, or contest the validity of, issued or
pending patents of third parties relating to Access Health's technology. There
can be no assurance that any of such licenses would be made available to Access
Health on acceptable terms, if at all, or that Access Health, if it were to
contest the validity of any issued or pending patents, would prevail. In
addition, Access Health could incur substantial costs in defending itself in
suits brought against Access Health on its patents or in bringing suits against
third parties to enforce Access Health's proprietary rights including patents.
Access Health also relies on copyright, trademarks, trade secret laws and
restrictions on disclosure, copying and transferring title. Despite Access
Health's precautions, it may be possible for unauthorized third parties to copy
aspects of Access Health's products or to obtain and use information that Access
Health regards as proprietary. Existing copyright laws afford only limited
practical protection. In addition, the laws of some foreign countries do not
protect Access
 
                                       84
<PAGE>
Health's proprietary rights to the same extent as do the laws of the United
States, which could be a factor if Access Health expands into markets outside
the United States.
 
EMPLOYEES
 
    As of February 28, 1998, Access Health had 727 full-time and 176 part-time
employees, including 498 registered nurses. None of Access Health's employees is
covered by a collective bargaining agreement, and Access Health believes that
its relations with its employees are good.

               ACCESS HEALTH MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF ACCESS HEALTH SHOULD BE READ IN CONJUNCTION WITH THE CONSOLIDATED
FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO INCLUDED HEREIN. THE
DISCUSSION IN THIS PROXY STATEMENT/PROSPECTUS AND NOTICE AND CONSENT
SOLICITATION STATEMENT CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS
AND UNCERTAINTIES. ACCESS HEALTH'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM
THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE OR
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, WITHOUT LIMITATION, THOSE DISCUSSED IN
THIS SECTION AND THE SECTIONS ENTITLED "RISK FACTORS," AND "ACCESS HEALTH
BUSINESS," AS WELL AS THOSE DISCUSSED ELSEWHERE IN THIS PROXY
STATEMENT/PROSPECTUS AND NOTICE AND CONSENT SOLICITATION STATEMENT.
 
GENERAL
 
    Access Health is a leading provider of personal health management products
and services to the health care industry. Access Health was founded in 1987 and
until 1993 primarily provided consumer health care information products and
services designed to help hospitals and other health care providers market their
services. Beginning in 1993, Access Health changed its focus to developing and
marketing personal health management products and services to health plans and
payors. In connection with the transition, Access Health incurred significant
development expenses for its PHA product, including expenses for the hiring and
training of personnel, capacity expansion and sales and marketing programs.
Because revenues from personal health management services were not sufficient to
cover start-up expenses, Access Health's gross margins decreased and operating
losses were sustained in the third and fourth quarters of fiscal 1994 and the
first quarter of fiscal 1995. Access Health returned to profitability in the
second quarter of fiscal 1995 and has achieved increased profitability each
quarter as additional members have been enrolled in PHA and gross margins
improved.
 
    PERSONAL HEALTH MANAGEMENT SERVICES.  Access Health's primary personal
health management product, PHA, is designed to generate recurring revenues
through a fee structure that is based on per-member per-month fees. Revenues are
generated principally from Access Health's PHA contracts. MCOs, care
organizations, health plans and large self-insured employers purchase PHA for
use by their members or employees in order to reduce unnecessary health care
utilization, improve member satisfaction and lower health care costs. Access
Health also earns fees for providing member communications services to its
customers.
 
    HEALTH SYSTEMS SERVICES.  Access Health also markets a line of personal
health management products and services to hospitals and other health care
providers. Those products include the ASK-A-NURSE-Registered Trademark- family
of products, Cancer HELPLINK-TM-, ACMS and the LIFE MATCH-Registered Trademark-
family of products. Access Health's revenues from these products include license
implementation fees as well as on-going fees for program support, teleservices,
and direct marketing activities.
 
RESULTS OF OPERATIONS--SIX MONTH PERIOD COMPARISON
 
    REVENUES.  Revenues consist of revenues from care management services and
licensing and support services. Revenues increased from $25.1 million during the
three months ended March 31, 1997 to $31.2 million during the three months ended
March 31, 1998, or 24%, and increased from $49.7 million for the six months
ended March 31, 1997 to $60.3 million, or 21% for the six months ended March 31,
1998.
 
    Revenues from care management services increased from $22.5 million during
the second quarter of fiscal 1997 to $28.1 million during the second quarter of
fiscal 1998, or 25%, and increased from
 
                                       87
<PAGE>
$44.4 million during the first six months of fiscal 1997 to $54.4 million, or
23% during the first six months of fiscal 1998, due to increases in membership
levels related to Access Health's contracts during these periods. As of March
31, 1998, approximately 26.1 million members were enrolled compared to
approximately 17.9 million members enrolled as of March 31, 1997. Average
revenue per-member per-month was $0.37 for the second quarter of fiscal 1998
compared to $0.43 for the second quarter of fiscal 1997. Average revenue
per-member per-month was $0.38 for the first six months of fiscal 1998 compared
to $0.45 for the first six months of fiscal 1997. The decrease in average
revenue per-member was primarily due to contract rationalizations where actual
utilization was meaningfully below the contract minimum. Access Health believes
that the decline in average revenue per-member has ended and average revenue
per-member will stabilize during the remainder of fiscal 1998.* Revenue from
Access Health's contracts is recognized ratably in accordance with contract
terms on the basis of per-member fees.
 
    Revenues from licensing and support services increased from $2.6 million
during the second quarter of fiscal 1997 to $3.1 million, or 19%, during the
second quarter of fiscal 1998, and from $5.3 million during the first six months
of fiscal 1997 to $5.8 million, or 9%, for the first six months of fiscal 1998.
Licensing and support services revenues include licensing implementations and
program support activities for FirstHelp-TM-, the
ASK-A-NURSE-Registered Trademark- family of products, CANCER
HelpLink-Registered Trademark-, Access Care Management
System-Registered Trademark- ("ACMS") and the LIFE MATCH-Registered Trademark-
family of products.
 
    COST OF REVENUES.  The cost of care management services revenues includes
the costs of operating Access Health's services centers, on-going client
consultation and charges for providing care management member communications
services. The gross margins for care management services were 48.8% during the
second quarter of fiscal 1997 and 44.9% during the second quarter of fiscal
1998, and 49.2% during the first six months of fiscal 1997 compared to 45.1% for
the first six months of fiscal 1998. The decrease in gross margin during the
second quarter of fiscal 1998 and for the six months ended March 31, 1998
compared to the same periods in fiscal 1997, is primarily due to adjusting
pricing terms on older contracts typically effective upon renewal dates during
fiscal 1997. Access Health does not anticipate that downward price adjustments
to contracts during the remainder of fiscal 1998 will have a material effect on
operating results.* Additional factors contributing to the decrease in gross
margin were operational inefficiencies experienced as a result of implementing a
common service platform in all care centers and absorbing the costs associated
with new product beta sites. Access Health expects that gross margins for care
management services will be lower during the second half of the fiscal year than
in the first half due primarily to a continuation of operating inefficiencies
related to the implementation of the common system platform.
 
    The cost of licensing and support services revenues includes the costs of
license implementations, on-going client consultation, annual users'
conferences, advertising materials, and other support services for
FirstHelp-TM-, ASK-A-NURSE-Registered Trademark-, CANCER
HelpLink-Registered Trademark-, Access Care Management
System-Registered Trademark- and LIFE MATCH-Registered Trademark- licensees. The
gross margin percentages for licensing and support services increased from 64.7%
during the second quarter of fiscal 1997 to 78.0% during the second quarter of
fiscal 1998, and from 61.9% during the first six months of fiscal 1997 to 76.7%
for the first six months of fiscal 1998 due to changes in product licensing mix
and increased efficiency resulting from organizational adjustments. While gross
margins for licensing and support can fluctuate, Access Health believes it is
currently operating near targeted gross margin levels for licensing and support
services.
 
    PRODUCT AND OTHER DEVELOPMENT EXPENSES.  Product and other development
expenses were $2.0 million, or 8.1% of revenues, during the second quarter of
fiscal 1997 and $1.7 million, or 5.4% of revenues, during the second quarter of
fiscal 1998. For the first six months of fiscal 1997, product and other
development expenses totaled $4.4 million, or 8.8% of revenues compared to $3.2
million, or 5.3% of revenues during the first six months of fiscal 1998.
 
    The decrease of 15.0% from the second quarter of fiscal 1997 to the second
quarter of fiscal 1998, and the decrease of 27.3% for the first six months of
fiscal 1997 to the first six months of fiscal 1998 is due to realizing cost
savings from the integration of the development teams of Access Health and
Informed
 
                                       88
<PAGE>
Access. Access Health expects product and other development expenses to increase
in coming quarters, but generally consistent with the current percentage of
revenues.*
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses were $1.9
million, or 7.6% of revenues, during the second quarter of fiscal 1997 and $2.5
million, or 7.9% of revenues, during the second quarter of fiscal 1998. For the
first six months of fiscal 1997, sales and marketing expenses totaled $4.2
million, or 8.5% of revenues, compared to $4.7 million, or 7.7% of revenues for
the first six months of fiscal 1998. For the quarter, as a percentage of
revenue, sales and marketing expenses increased slightly by 3% over the second
quarter of fiscal 1997. As a percentage of revenue, sales and marketing expenses
declined for the six months ended March 31, 1998 due to realizing cost savings
from the integration of the sales teams of Access Health and Informed Access.
Access Health expects sales and marketing expenses to increase in coming
quarters, but generally consistent with the current percentage of revenues.*
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
were $2.2 million, or 8.7% of revenues, during the second quarter of fiscal 1997
and $2.5 million, or 8.1% of revenues, during the second quarter of fiscal 1998.
For the first six months of fiscal 1997, general and administrative expenses
totaled $4.6 million, or 9.2% of revenues, compared to $4.8 million, or 8.0% of
revenues for the first six months of fiscal 1998. As a percent of revenue,
general and administrative expenses decreased during the second quarter of
fiscal 1998 and the first six months of fiscal 1998 when compared to the prior
fiscal year due to realizing cost savings from the integration of Access Health
and Informed Access' management teams. Access Health expects general and
administrative expenses to increase in coming quarters, but generally consistent
with the current percentage of revenues.*
 
    TRANSACTION COSTS.  Transaction costs of $6.3 million were one-time charges
recorded in the first quarter of fiscal 1997 associated directly with the merger
of Access Health with Informed Access and CRS and consists primarily of
professional fees and services of approximately $5.2 million.
 
    INTEGRATION AND RESTRUCTURING COSTS.  Integration and restructuring costs
related to the mergers of Informed Access and CRS were recorded in the amounts
of $7.0 million and $2.7 million during the first and fourth quarters of fiscal
1997, respectively. Integration and restructuring costs include: $7.1 million
for severance, outplacement and relocation costs specifically related to the
merger; $1.2 million related to the closure and elimination of duplicate leased
facilities, primarily corporate headquarters, a sales office and a call center;
and $1.3 million related to the write-off of computer hardware and other assets
which were made obsolete as a result of the merger and duplicate information
systems. The remaining merger-related accrual at March 31, 1998 was
approximately $1.9 million and includes: $1.1 million for severance,
outplacement and relocation costs; $0.5 million related to the closure and
elimination of duplicate leased facilities; and $0.3 million related to the
write-off of computer hardware and other assets. Total expected cash
expenditures relating to the merger charge are estimated to be approximately
$6.7 million of which approximately $4.8 million was disbursed prior to March
31, 1998. Termination benefits received by employees terminated through
September 30, 1997 were approximately $5.6 million. The remaining severance and
outplacement amounts are expected to be paid during the current fiscal year.
 
    INCOME FROM OPERATIONS.  Operating income increased from $6.5 million during
the second quarter of fiscal 1997 to $8.4 million during the second quarter of
fiscal 1998, and increased from a loss of $1.4 million for the first six months
of fiscal 1997 to a profit of $16.4 million during the same period in fiscal
1998. As indicated above, the changes are attributable to increasing revenues
and decreased ongoing operating expenses, and to the transaction, integration
and restructuring expenses recorded during the first six months of fiscal 1997,
but absent from the results for the first six months of fiscal 1998.
 
    INCOME TAXES  Access Health recorded an income tax provision of
approximately $1.4 million and $3.5 million for the three months ended March 31,
1997 and 1998, respectively, an income tax benefit of approximately $132,000 for
the six months ended March 31, 1997 and an income tax provision of approximately
$6.9 million for the six months ended March 31, 1998, respectively. During
fiscal 1997,
 
                                       89
<PAGE>
Access Health, for tax purposes, liquidated one of its subsidiaries, allowing it
to utilize the net operating loss of the subsidiary and reduce the valuation
allowance by $3,368,000. Additionally, during fiscal 1997, Access Health
recorded a deferred tax asset of approximately $6.0 million resulting from
temporary differences in the recognition of certain expenses for book and tax
purposes.
 
    Realization of Access Health's net deferred tax asset is dependent upon
Access Health generating sufficient United States federal taxable income
(approximately $17.0 million) in future years to obtain benefit from the
reversal of net deductible temporary differences and from tax credit
carryforwards. Access Health's management believes that, on a more likely than
not basis, Access Health's recorded net deferred tax asset is realizable. The
amount of deferred tax assets considered realizable is subject to adjustment in
future periods if estimates of future United States federal taxable income are
reduced.
 
    OTHER INCOME.  Access Health generates interest and other income from cash
balances and available-for-sale securities. Interest and other income increased
from $336,000 to $919,000, or 173.5% in the second quarter of fiscal 1997 and
1998, respectively, and from $715,000 to $1,677,000, or 134.6% for the first six
months of fiscal 1997 and 1998, respectively due to the increase in cash and
equivalents and available-for-sale securities from $44.0 million at March 31,
1997 to $75.8 million at March 31, 1998.
 
    EFFECTS OF INFLATION AND CHANGING PRICES.  Inflation and changing prices
have not had a material effect on Access Health's operations and, at current
levels, are not expected to in future years.*

    REVENUES.  Revenues are comprised of revenues from care management services
and revenues from licensing and support services. Revenues increased 100.0% from
$36.0 million in fiscal 1995 to $72.1 million in fiscal 1996 and 44.7% to $104.3
million in fiscal 1997.
 
    Revenues from care management services increased 131.0% from $26.5 million
in fiscal 1995 to $61.2 million in fiscal 1996 and 53.2% to $93.7 million in
fiscal 1997 because of an increase in members enrolled under Access Health's
care management contracts. As of September 30, 1997, approximately 22.3 million
members were enrolled, an increase of 54.9% compared to approximately 14.4
million enrolled as of September 30, 1996. 4.3 million were enrolled as of
September 30, 1995. Average care management revenue per-member per-month
decreased from $0.86 in fiscal 1995 to $0.52 in fiscal 1996 and $0.42 in fiscal
1997. Average revenue per-member per-month is a function of both membership size
and monthly call experience ("utilization"). Many of the older contracts
contained price terms providing for minimum membership commitments and a
utilization floor, which occasionally resulted in clients paying for members not
yet enrolled or utilization rates in excess of actual experience. The decrease
in average revenue per-member from 1995 to 1996 was primarily due to increases
in the average number of members per customer. The decrease in average revenue
per-member from 1996 to 1997 was primarily due to contract renewals and
renegotiations where actual utilization was meaningfully below the contract
minimum. Access Health believes that average per-member fees will decline
slightly in the first half of fiscal 1998 and will then stabilize during the
second half of fiscal 1998.* Revenue from care management contracts are
recognized ratably on a per-member per-month basis commencing upon the
enrollment of members.
 
    Revenues from licensing and support services increased 14.7% from $9.5
million in fiscal 1995 to $10.9 million in fiscal 1996 and decreased 3.0% to
$10.6 million in fiscal 1997. Licensing and support services revenues include
licensing, implementation, program support and teleservicing fees associated
with Access Health's FirstHelp-TM-, ASK-A-NURSE-Registered Trademark-, Cancer
HELPLINK-Registered Trademark-, ACMS and HealthSelect-TM- licensed products.
Revenues from patient education software sales are also included. Access Health
expects that licensing and software support revenues will remain constant or
increase moderately in terms of absolute dollars while at the same time decline
as a percentage of total revenues due to revenue growth from other products and
services.*
 
    COST OF REVENUES.  The cost of care management services revenues includes
the costs of operating Access Health's care centers, on-going client
consultation and charges for providing care management member communications
services. The gross margin percentages for care management services were 26.8%,
43.3% and 47.5% for fiscal 1995, 1996 and 1997, respectively. Gross margins for
care management services improved from 1995 to 1996 and 1996 to 1997 because
economies of scale and operating efficiencies were achieved by virtue of the
growth in care management enrollments, as previously discussed.
 
    The cost of licensing and support services revenues includes the costs of
licensing implementations, call processing, on-going client consultation, annual
users' conferences, advertising materials, and other support services for
FirstHelp-TM-, ASK-A-NURSE-Registered Trademark-, Cancer
HELPLINK-Registered Trademark-, ACMS and HealthSelect-TM- licensees. It also
includes costs associated with publishing and distributing patient education
software to health care providers. The gross margin percentages for licensing
and support services were 47.9%, 51.0% and 69.4% for fiscal 1995, 1996 and 1997,
respectively. Year to year fluctuations in gross margins are the result of
changes in the mix of product and services sales with varying margins. The
increase from fiscal 1996 to fiscal 1997 is due to the replacement of lower
margin ASK-A-NURSE-Registered Trademark- business with higher margin
FirstHelp-TM- licensing and patient education software sales.
 
    PRODUCT AND OTHER DEVELOPMENT EXPENSES.  Product and other development
expenses increased 98.5% from $3.3 million in 1995 to $6.5 million in 1996 and
21.0% to $7.9 million in fiscal 1997. These costs relate to enhancements of
Access Health's care center systems and clinical applications, and the
development of other products and services intended to serve selected markets.
Beginning in fiscal 1996, product development also included costs associated
with the development of new disease management products
 
                                       91
<PAGE>
and PHA OnLine. Access Health expects product and other development expenses to
remain relatively constant in fiscal 1998 as it continues to make investments in
care management and disease management products and services.*
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist of
expenses related to both the care management and license and support services
products. These expenses increased 72.6% from $5.5 million in 1995 to $9.5
million in 1996 and decreased 5.9% to $8.9 million in 1997. Sales and marketing
expenses as a percentage of revenues were 15.2%, 13.1% and 8.5% in fiscal 1995,
1996 and 1997, respectively. Increased sales and marketing expenses from fiscal
1995 to fiscal 1996 reflected higher levels of lead generation activity,
expansion of the sales team and increased sales commissions related to the
increase in revenues. The decrease in sales and marketing expenses from fiscal
1996 to fiscal 1997 was the result of synergies achieved by the post-merger
consolidation of sales and marketing activities. Sales and marketing expenses
declined as a percentage of revenues from fiscal 1995 to fiscal 1996 and fiscal
1997 due to the growth in care management services revenues previously
discussed.
 
    Sales and marketing expenses will likely increase in fiscal 1998 in terms of
absolute dollars as Access Health pursues its strategy of selling and servicing
an expanding suite of care management and disease management products and may
increase as a percentage of revenues.*
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased 128.9% from $4.5 million in 1995 to $10.4 million in 1996 and
decreased 17.1% to $8.6 million in 1997. As a percentage of revenue, general and
administrative expenses were 12.6%, 14.4% and 8.3% in 1995, 1996 and 1997,
respectively. The expense increase from 1995 to 1996 reflects increased expenses
for management information systems and additional finance, human resources and
executive level personnel. The decline from fiscal 1996 to fiscal 1997 was the
result of synergies achieved by the post-merger consolidation of redundant
general and administrative activities.
 
    TRANSACTION COSTS AND INTEGRATION AND RESTRUCTURING COSTS.  Transaction
costs of $6.3 million reflect charges associated directly with the merger of
Access Health with Informed Access and CRS and included professional fees of
approximately $5.2 million. Integration and restructuring costs related to the
mergers were recorded in the amounts of approximately $7.0 million and $2.7
million during the first and fourth quarters of fiscal 1997, respectively.
Integration and restructuring costs include: approximately $7.1 million for
severance, outplacement and relocation costs specifically related to the merger;
approximately $1.2 million related to the closure and elimination of duplicate
leased facilities, primarily corporate headquarters, a sales office and a call
center; and approximately $1.3 million related to the write-off of computer
hardware and other assets which were made obsolete as a result of the merger and
duplicate information systems.
 
    The remaining merger-related accrual at September 30, 1997 was approximately
$3.1 million. Total expected cash expenditures relating to the merger charge are
estimated to be approximately $7.1 million, of which approximately $4.1 million
was disbursed prior to September 30, 1997. Termination benefits received by
employees terminated through September 30, 1997 were approximately $4.5 million.
The remaining severance and outplacement amounts are expected to be paid within
the next twelve months.
 
    INCOME (LOSS) FROM OPERATIONS.  Operating income (loss) increased from a
loss of $1.7 million in fiscal 1995 to income of $5.7 million in fiscal 1996 and
$10.4 million in fiscal 1997. Excluding one time non-recurring transactions,
integration and restructuring costs, operating income was $26.4 million in
fiscal 1997. The loss from operations in fiscal 1995 can be attributed to losses
incurred by Informed Access prior to the merger, which, while still in its
formative stage, made significant investments in developing a sophisticated
clinical approach to providing care management services. The change to
profitability in fiscal 1996 and further increases in profitability in fiscal
1997 are due to economies of scale associated with increased enrollments and
revenues combined with synergies achieved by combining operating companies.
 
    NON-OPERATING INCOME (EXPENSE).  Access Health generates net interest income
primarily from cash balances and investments. Interest and other income
increased from $877,000 in fiscal 1995 to $1.6 million
 
                                       92
<PAGE>
in fiscal 1996 and to $2.2 million in fiscal 1997. The increases are primarily
due to increasing cash and short-term investment balances resulting from
positive cash flow from operations. The increase in fiscal 1996 was due to
additional capital raised in December 1995 by Access Health's secondary public
offering of its common stock. Interest expense of $150,000, $186,000, and
$324,000 in fiscal 1995, 1996, and 1997, respectively, is associated with
long-term leases for office equipment and certain other short term indebtedness
including notes payable to related parties.
 
    During fiscal 1997, American Health Network's ("AHN") majority owner and
principal financial sponsor, The Providence Journal Company ("PJC") was acquired
by AH Belo Corp ("Belo"). Subsequent to Belo's acquisition of PJC in February
1997, Belo indicated that it did not intend to provide additional financing to
AHN and pursued alternate financing and operating strategies for AHN. On July
31, 1997, Belo terminated its 65 percent ownership interest in AHN when a
previously announced agreement to sell its interest in AHN to Columbia/HCA
Healthcare Corp. was terminated in late July when Columbia failed to close on
the transaction. As a result of losing its principal financial sponsor and not
being able to obtain additional financing, AHN suspended daily operations and
furloughed the majority of its employees. Accordingly, Access Health determined
the equity investment and the subordinated debenture were not recoverable and
they were written off in the fourth quarter of fiscal 1997.
 
    INCOME TAXES.  Access Health recorded an income tax benefit of $242,000 in
1995, an income tax provision of $6.1 million in fiscal 1996, and an income tax
benefit of $2.4 million in fiscal 1997, respectively. During 1997, Access
Health, for tax purposes, liquidated one of its subsidiaries, allowing it to
utilize the net operating loss of the subsidiary and reduce the valuation
allowance by $3,368,000. Additionally, during 1997, Access Health recorded a
deferred tax asset of approximately $6.0 million resulting from temporary
differences in the recognition of certain expenses for book and tax purposes.
 
    Realization of Access Health's net deferred tax asset is dependent upon
Access Health generating sufficient United States federal taxable income
(approximately $17.0 million) in future years to obtain benefit from the
reversal of net deductible temporary differences and from tax credit
carryforwards. Access Health's management believes that, on a more likely than
not basis, Access Health's recorded net deferred tax asset is realizable.* The
amount of deferred tax assets considered realizable is subject to adjustment in
future periods if estimates of future United States federal taxable income are
reduced.
 
    EFFECTS OF INFLATION AND CHANGING PRICES.  Inflation and changing prices
have not had a material effect on Access Health's operations and, at current
levels, are not expected to in future years.*
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Access Health has funded its operations through the sale of equity
securities, cash flow from operations and incurrence of debt. Cash provided by
operations increased 102.2% from $4.6 million for fiscal 1995 to $9.1 million
for fiscal 1996 and 130.8% to $21.0 million for fiscal 1997. Cash provided by
operations during the first six months of fiscal 1998 was $15.3 million compared
with $10.0 million for the first six months of fiscal 1997. Access Health raised
net proceeds of $29.5 million from a public offering of its Common Stock in the
first quarter of fiscal 1996. As of March 31, 1998 Access Health held cash and
equivalents and available-for-sale securities totaling $75.8 million.
 
    Accounts and licenses receivable increased 89.7% from $6.8 million in fiscal
1995 to $12.9 million in fiscal 1996 primarily as a result of increased revenue
from PHA contracts. Accounts and licenses receivable decreased 3.1% to $12.5
million in fiscal 1997 due to a reduction in payment cycle.
 
    In fiscal 1995, 1996 and 1997 Access Health used cash and equivalents to
invest in short-term investments. In fiscal 1995 and 1996 Access Health made
significant additions to property and equipment to expand its call center
operations. During April 1996, Access Health invested $5.0 million in AHN. In
exchange, Access Health received a limited partnership interest in AHN. In
January 1997, Access Health elected to invest an additional $5 million in AHN in
the form of a convertible debenture. As discussed above, Access Health recorded
a $10.0 million charge to operations relating to AHN in the fourth quarter of
fiscal 1997.
 
                                       93
<PAGE>
    Access Health's long-term debt and capital lease obligations together have
been reduced to a total of $312,000 as of March 31, 1998.
 
    During the first six months of fiscal 1998, the Company purchased
approximately $3.2 million of property and equipment. The Company expects to
purchase additional capital equipment during the balance of fiscal 1998 to
further integrate and expand call centers and system capacity, and to expand the
Company's corporate infrastructure.*
 
    Access Health believes its current capital resources are adequate to fund
cash needs for anticipated operating levels for at least the next twelve
months.* Access Health also may use capital resources in connection with
business expansion that may include the acquisition of complementary product
lines or businesses during fiscal 1998 or beyond.*
 
    In 1997, Access Health adopted SFAS 128, which was required to be adopted on
December 15, 1997. This statement establishes standards for computing and
presenting basic and diluted earnings per share. Under this statement, basic
earnings or loss per share is computed by dividing the net earnings or loss by
the weighted average number of shares of common stock outstanding. Diluted
earnings or loss per share is determined by dividing the net earnings or loss by
the sum of (1) the weighted average number of common shares outstanding, (2) if
not anti-dilutive, the number of shares of convertible preferred stock as if
converted upon issuance, and (3) if not anti-dilutive, the effect of outstanding
stock options determined utilizing the treasury stock method. As a result of
adopting SFAS 128, reported (loss) earnings per share for the years ended
September 30, 1995, 1996 and 1997 were restated. The effect of this accounting
change on previously reported (loss) earnings per share was as follows:

(1) Options granted under Access Health's 1989 Plan and under its Supplemental
    Stock Plan. The option exercise price of all incentive stock options granted
    under the 1989 Plan is generally equal to the fair market value of the
    shares of Common Stock on the date of grant; the options have terms of seven
    to ten years and generally vest at the rate of 20% of the shares subject to
    the option for each year that the optionee remains in continuous status as
    an employee or consultant.
 
(2) Potential realizable value is based on the assumption that the Common Stock
    of Access Health appreciates at the annual rate shown (compounded annually)
    from the date of grant until the expiration of the option term. These
    numbers are calculated based on the requirements promulgated by the
    Securities and Exchange Commission and do not reflect Access Health's
    estimate of future stock price growth.
 
(3) Includes 75,000 shares subject to option which were repriced from the
    original exercise price pursuant to grant in fiscal year 1996.

COMPENSATION OF DIRECTORS
 
    Outside directors were paid $2,500 quarterly and reimbursed for certain
expenses incurred in connection with attendance at board and committee meetings
during fiscal 1997. The Company paid $50,000 to Brent Rider, who resigned as a
director in November 1997, as a reward for his service in initiating the merger
of Informed Access with Access Health. Outside directors are granted
nonstatutory stock options under the 1995 Director Option Plan. As of fiscal
year end 1997, there were four outside directors. Please see "Employee Benefit
Plans--1995 Director Option Plan" for information with respect to the 1995
Director Option Plan.
 
EMPLOYMENT CONTRACTS, TERMINATION AND CHANGE OF CONTROL ARRANGEMENTS
 
    The 1995 Director Option Plan provides that upon a change in control of
Access Health, the unvested portion of all options held by Outside Directors
shall become immediately exercisable. The 1989 Plan provides that in the event
of a change in control of Access Health, outstanding stock options and stock
purchase rights shall be assumed or equivalent options or rights shall be
substituted by the successor entity. Unless such successor corporation agrees to
such assumption or substitution, Access Health's Board of Directors must provide
for the options or rights to become immediately exercisable in full. In
addition, option agreements and stock purchase agreements for executive officers
at the Vice President level and above provide that options under such agreements
become immediately exercisable in full in the event of a change in control of
Access Health. Additionally, grants made to all employees in 1997 contained
provisions for such immediate exercise upon a change of control.
 
    The Company entered into a three year employment agreement with Joseph
Tallman in November 1996. The agreement provides Mr. Tallman with a base salary
of $100,000 which increases to $180,000 on the first anniversary of the
agreement or once the Company attains certain earnings targets. The Company's
Board of Directors and Mr. Tallman later agreed that his base salary would not
be increased until the beginning of calendar year 1998. Mr. Tallman is also
eligible to participate in the Company's bonus plan. Moreover, the agreement
provides Mr. Tallman with an option to purchase 60,000 shares of Common Stock of
the Company, which vests over five years. Such option becomes immediately
exercisable upon a merger or sale of the Company. In addition, if Mr. Tallman is
terminated without cause or constructively terminated, all stock options he
holds become immediately exercisable and he is entitled to a
 
                                      101
<PAGE>
severance payment equal to his base compensation for the remainder of the term
of the agreement, or twenty-four months in the event of a constructive
termination due to a change of control.
 
    The Company entered into an employment agreement with Kenneth Plumlee,
former Chief Executive Officer and director, in December 1996 that was amended
in April 1997. The agreement, as amended, provides Mr. Plumlee with a base
salary of $150,000, a deferred compensation benefit of $680,000 payable in
January 1997, and an additional severance benefit of $227,865. Pursuant to the
agreement, Mr. Plumlee also received immediate vesting of 36,000 shares of the
Company's Common Stock subject to a stock option he holds. In addition, under
the terms of the agreement, Mr. Plumlee is entitled to immediate vesting of all
of his Access Health stock options and a severance payment equal to the payment
of his base salary until September 30, 1998, upon the following conditions: (i)
if he is terminated without cause; (ii) if he is not re-elected as a director of
the Company by the stockholders of the Company; (iii) in the event of a change
in control of the Company; (iv) in the event of his death or disability or (v)
if he and the Chief Executive Officer of the Company mutually agree to terminate
Mr. Plumlee's services under this agreement or as a member of the Board of
Directors prior to September 30, 1998. In connection with this agreement, Mr.
Plumlee also agreed to noncompete and nonsolicitation restrictions that will
remain in effect until September 30, 1998.
 
    The Company entered into a separation agreement and mutual release with
Thomas Gardner in April 1997. The agreement provided Mr. Gardner with a prorated
bonus for fiscal year 1997 of $105,000, a severance payment of $600,000, and a
payment for accrued vacation equal to $23,170. Under the agreement, 2,000 shares
of the Company's restricted stock held by Mr. Gardner became fully vested and
stock options in the amount of 250,000 shares and 200,000 shares of the
Company's stock held by Mr. Gardner became exercisable, subject to vesting, for
up to 100,000 shares and 92,000 shares, respectively, until the termination of
such options on April 30, 1999. In connection with this agreement, Mr. Gardner
also agreed to noncompete and nonsolicitation restrictions for a period of one
year.
 
    The Company entered into a two year employment/consulting agreement with
John Crisan in July 1997. The agreement provides Mr. Crisan with a base salary
of $152,250 and eligibility for limited participation in the Company's
management incentive plan. If Mr. Crisan is terminated without cause, he is
entitled to a severance payment equal to his base compensation for the remainder
of the term of the agreement. If he is constructively terminated due to a change
in control prior to May 1, 1998, he is entitled to a severance payment equal to
twenty-four months of his base compensation. Mr. Crisan left the Company in May
1998.
 
    In addition to the above agreements, the Named Executive Officers of the
Company (excluding Kenneth Plumlee, Richard Miller, and Thomas Gardner) entered
into standardized severance agreements with the Company which expire in November
1998. These agreements all provide for accelerated vesting of options held by
such officers in the event of a merger or sale of the Company. In addition,
under the form agreement, if an officer is terminated without cause or
constructively terminated, all stock options he holds become immediately
exercisable and he is entitled to a severance payment equal to his base
compensation for the remainder of the term of the agreement or one year
(whichever is longer), or twenty-four months in the event of a constructive
termination due to a change in control.
 
    There are no other employment contracts between Access Health and any of the
Named Executive Officers, and there are no other compensatory plans or
arrangements with respect to a Named Executive Officer which will result in
payments upon resignation, retirement, or any other termination of such
executive officer's employment or from a change of control of Access Health.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Compensation Committee, during the 1997 fiscal year, consisted of Frank
G. Washington and Alice H. Lusk. Kinney L. Johnson has since replaced Ms. Lusk
on the Compensation Committee for fiscal 1998. No member of either committee is
or has been an officer or employee of Access Health. No
 
                                      102

interlocking relationship exists between Access Health's Board of Directors or
Compensation Committee and the board of directors or compensation committee of
any other company.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    On March 30, 1998, Access Health made a bridge loan to Julie A. Brooks in
the amount of $165,000. The loan is evidenced by a one-year promissory note

Access Health, Joseph P. Tallman received a bonus of $300,000 as a reward for
his service in initiating and negotiating such merger. See the Summary

BUSINESS
 
THE COMPANY
 
    InterQual develops and markets criteria which assist health care payors and
providers in making and evaluating level of care and clinical appropriateness
decisions. The Criteria, which are marketed to MCOs, indemnity insurers,
hospitals, integrated delivery systems, physician groups, independent practice
associations, third party administrators and utilization review organizations,
are used after determining patient specific clinical facts and either signal
accord with the physician's choice of a proposed health care service or indicate
a more appropriate alternative. By guiding and documenting the appropriateness
of resource-use decisions, the Criteria are designed to avoid excessive health
care costs and protect against underutilization of needed services.
 
    InterQual licenses its Criteria either directly to end users or through its
alliance partners program (see "InterQual Business--Sales and Marketing").
Licensing fees are payable annually and are based on covered lives, hospital
beds or number of reviews. A substantial majority of InterQual's Criteria
products are licensed in printed form. InterQual's product development efforts
are currently addressing its customers' needs to have the Criteria delivered in
electronic form. InterQual also provides implementation training and consulting
services to its licensees.
 
    InterQual, which is certified by the National Committee for Quality
Assurance as a Credential Verification Organization, also conducts physician and
ancillary health care provider credentialing services for MCOs through its
CredFile-Registered Trademark- software. In addition, InterQual is developing a
Windows-based credentialing product, CredWin-TM-.
 
    InterQual was incorporated in Illinois in 1976 and was reincorporated in
Delaware in 1979. InterQual is headquartered at 293 Boston Post Road West,
Marlborough, MA 01752, telephone (508) 481-1181 and also has an office in North
Hampton, New Hampshire.
 
THE MARKET
 
    The rate of health care spending increases in the United States continues to
exceed GDP growth. The Congressional Budget Office expects national health
expenditures to reach 13.7% of GDP or slightly more than $1.1 trillion in 1997.
Containment of health care costs has become a national priority. As a result,
cost-conscious managed health care programs have increasingly influenced the
health care system. These managed care programs have traditionally reduced the
cost of health care by restricting access to care through administrative
techniques such as pre-authorization, pre-certification, and concurrent and
retrospective review programs to manage members' use, through financial
management techniques such as transferring cost risk to providers and by
negotiating to reduce payments for hospital and physician services, drugs and
ancillary health care services. InterQual believes that while these techniques
have been moderately successful in controlling costs, there is increasing
evidence that their use has had an impact on the quality of health care and
given rise to the following issues:
 
    A CONSUMER BACKLASH AGAINST THE QUALITY OF MANAGED CARE.  Consumer concern
about overt financial incentives and arbitrary restrictions on utilization
employed to suppress health care delivery costs has enhanced demand for products
which provide objective guidelines for appropriate care and protect against
underutilization.
 
    RISK OF LITIGATION.  MCOs' exposure to the risk of litigation for patient
harm attributable to the delay or withholding of service occasioned by cost
containment programs has served to heighten demand for objective clinical
decision support guidelines to assure that the appropriate care is provided and
to demonstrate and document medically appropriate health care decisions.
 
                                      107
<PAGE>
    PROVIDER FINANCIAL RISK.  Payors are responding to escalating costs by
shifting some portion of the financial risk associated with the delivery of
health care to providers, by capitated payment arrangements. As providers assume
more risk under capitation arrangements, they too seek an objective standard of
appropriate medical care that is comprehensive, patient-specific, clinically
defensible and acceptable to consumers.
 
    InterQual believes clinical decision support systems play a significant role
in improving the quality as well as reducing the cost of health care delivery.
Such tools provide balance to managed care's cost control strategies by
promoting and documenting clinical appropriateness.
 
    The market for InterQual's Criteria products is driven by the combination of
a cost conscious managed care environment, high health care costs and
inadequacies in the clinical decision making process. Clinical decision support
systems, such as the Criteria, are used to assess the effectiveness, economics
and quality of health care decisions and to assist providers with real time
decision support at the point of care. The Criteria assist MCOs by (i)
channeling demand to more cost effective services thereby reducing the need for
premium increases; (ii) fostering consumer trust by using clinically relevant,
objective standards; and (iii) justifying the quality of care through
quantifiable clinical reporting. In addition, the Criteria assist providers in
managing the financial risk which is being shifted to them by insurers under
capitation and instituting demand and resource use control measures while
demonstrating and documenting appropriate clinical care.
 
INTERQUAL CRITERIA PRODUCTS
 
    The Criteria, which are developed in an iterative process using information
from a literature review and input from InterQual's clinical development staff
and a panel of physicians in both academia and private practice, provide an
explicit clinical rationale for care decisions. The Criteria are annotated with
explanatory notes and supported by references to the current medical literature.
 
    InterQual is constantly developing new products and enhancing existing
proprietary intellectual property. InterQual relies on a combination of
copyright, trade secrets, confidentiality procedures and contractual provisions
to protect its intellectual property. InterQual has developed an automated
software product, AutoBook2 for Windows-TM-, for the delivery of the Criteria
and an automated Criteria Development System ("CDS") for the in-house
development of its Criteria. InterQual has filed a patent application to protect
its AutoBook2 for Windows-TM- and intends to file patent applications to protect
its CDS system.
 
    InterQual's main Criteria products are:
 
    ISD-REGISTERED TRADEMARK- (INTENSITY/SEVERITY/DISCHARGE) CRITERIA FOR ACUTE,
SUBACUTE, REHABILITATION AND HOME CARE.  ISD-Registered Trademark-Criteria
provide decision support for admission to, stay in and discharge from the
appropriate level of care setting. ISD-Registered Trademark- correlates
patient-specific clinical findings with the care setting and is thereby intended
to help manage the selection of site and the length and level of care.
 
    ISP-TM- (INDICATIONS FOR SURGERY AND PROCEDURES).  ISP-TM- defines patient
specific clinical thresholds for performing most surgical and other invasive
procedures. ISP-TM- is designed to serve as a tool in promoting necessary
surgery and preventing costly and inappropriate surgery and the patient risk
inherent therein.
 
    ISX-TM- (INDICATIONS FOR IMAGING STUDIES AND X-RAYS).  ISX-TM- provides
decision support for imaging studies. This Criteria product covers 83 studies
including MRI, CT and ultrasound. ISX-TM- is designed to prevent unnecessary
testing, manage provider and patient demand, enable rapid, consistent and
reliable review and promote appropriate sequencing of imaging studies.
 
    IWC-TM- (INDICATIONS FOR WORKERS' COMPENSATION CLINICAL MANAGEMENT).  The
IWC-TM- Criteria product contains certain specific components of the
ISD-Registered Trademark-, ISX-TM- and ISP-TM- Criteria products. It provides
patient-
 
                                      108
<PAGE>
specific, clinical thresholds for workers' compensation related surgeries,
imaging studies and hospital care. It is designed to reduce medical costs
related to workplace injuries.
 
    IPS-TM- (INDICATIONS FOR PRIMARY AND SPECIALTY CARE MANAGEMENT).  IPS-TM- is
used to define the scope of primary care management and the patient specific
thresholds for specialist care for almost all frequently seen presentations and
diagnoses. This Criteria product is designed to be applicable to all primary and
specialist care settings. It contains best practice therapeutic and diagnostic
strategies to be undertaken prior to specialist involvement, directs the care to
the most appropriate specialist and specifies the scope of specialist care
needed. It currently covers cardiology, gastroenterology, endocrinology and
pulmonology. Criteria for other clinical areas are under development.
 
    SIMPLUS-TM-.  SIMPlus-TM- combines two existing InterQual products: SIM-TM-
(Surgical Indications Monitoring) and IPM-Registered Trademark- (Invasive
Procedures Monitoring). It is designed for retrospective monitoring of the
appropriateness of surgical and non-surgical invasive procedures.
 
    InterQual's Criteria are provided both in book form and in a Windows-based
software product called AutoBook2 for Windows-TM-. AutoBook2 for Windows-TM- can
operate either in a stand alone or in a networked client/server environment.
InterQual has developed interfaces which support information interchange with a
variety of third party applications. Such systems automate the process of
clinical and demographic data capture, aggregation, analysis and reporting, and
the integration of Criteria-based decision support with enterprise-wide
financial and other business data.
 
SALES AND MARKETING
 
    InterQual employs eight regional licensing managers, four of whom have
responsibility for clients with more than 50,000 covered lives within defined
geographic regions and four of whom have responsibility for clients with less
than 50,000 covered lives within defined geographic regions.
 
    InterQual also distributes its Criteria through a recently established
alliance partners ("AP") program. InterQual's APs are third-party vendors of
special applications and enterprise wide health care information systems. Each
AP provides end users the ability to access InterQual's Criteria from such end
user's AP software.
 
    InterQual promotes its Criteria through distribution of marketing materials,
hosting Criteria conferences and participation in trade shows. In addition,
InterQual provides product demonstrations and industry presentations and its
senior management are regular contributors to various relevant industry journals
and magazines. InterQual also promotes products through its web site.
 
CUSTOMERS, SERVICE AND SUPPORT
 
    InterQual's Criteria are used by almost every type of organization within
the spectrum of health care delivery, including MCOs, indemnity insurers,
hospitals, integrated delivery systems, physician groups, independent practice
associations, third party administrators, utilization review organizations and
public programs. Today, InterQual's customers include over 500 licensed health
plans (including 10 of the largest 12 HMOs), major indemnity insurers and over
1,200 hospitals.
 
    InterQual supports new licensees and its existing customer base through its
professional services department, providing on-site and off-site Criteria
implementation and training. In addition, InterQual's customer services group
provides first line customer assistance through a toll free service. The
customer services group works in concert with the professional services,
Criteria and technical development and sales departments for the resolution of
customer inquires. Additional education and training programs are held regularly
and additional fee based consulting services are available.
 
    InterQual also offers an education and certification program leading to
designation as a Certified Professional in Utilization Review under which
InterQual certifies health care professionals.

<PAGE>
PRODUCT DEVELOPMENT
 
    The integrity of the Criteria product is based on InterQual's comprehensive
clinical development process and its annual Criteria enhancement program. New
Criteria development involves a process of identifying a market need for
objective, clinically-based Criteria, researching and documenting the relevant
medical literature and an extended iterative development process in which
extensive feedback is sought from a national consulting network of academic and
practicing physicians. The result is the development of a product which
incorporates an up-to-date consensus of medical practice guidelines.
 
    InterQual also continually evaluates developments in information technology
for their potential application to improving the utility and value of its
products for its clients. InterQual directs its development efforts towards
technologies intended to have application in current products and which will
also become core technologies for future products.
 
COMPETITION
 
    The market for decision support systems is highly competitive, with many
companies offering administrative and financial decision support systems with
varying capabilities for clinical data acquisition and analysis, and others
targeted at providing real-time clinical decision support for physicians. Some
of these companies are larger and have greater resources than InterQual and
offer a broader range of products than does InterQual. As a result, such
competitors may appear more attractive to customers as a single source for
broader product offerings.
 
    InterQual believes its principal competitors to be Health Risk Management,
Milliman & Robertson, Optimed Medical Systems, Value Health Sciences and The Oak
Group. Except for The Oak Group, these companies' clinical decision support
products are a small component of a much broader product offering. In addition,
InterQual faces competition from some health care organizations which have
developed guidelines in-house.
 
EMPLOYEES
 
    As of May 1, 1998, InterQual had 130 employees, 86 of whom are based out of
the Marlborough, Massachusetts office and the remainder of whom work out of the
North Hampton, New Hampshire office. None of InterQual's employees is
represented by a labor union. InterQual has not experienced any work stoppages
to date and believes its relationship with its employees is good.
 
FACILITIES
 
    InterQual leases a 19,252 square foot facility in Marlborough,
Massachusetts, which houses corporate functions, sales and marketing, product
development, including clinical services and software development and technical
services and credentialing. InterQual also leases 10,898 square feet of office
space in North Hampton, New Hampshire, which houses professional services and
distribution.
 
LEGAL PROCEEDINGS
 
    InterQual is not currently party to any material litigation.

GENERAL
 
    InterQual derives revenues from licensing its criteria, providing
professional services which comprise implementation and education, conducting
credentialing services for managed care organizations and providing training and
consulting services to health care organizations. Training and consulting
services have been substantially decreasing as a percentage of revenues since
1995. InterQual licenses its criteria directly to end users and through a
business partners program. Licensees include managed care organizations,
hospitals, integrated delivery systems, physician groups, independent practice
associations, third party administrators, utilization review organizations and
public programs located throughout the U.S. and internationally.
 
    Revenues from the licensing of its criteria are received and deferred upon
the signing of a license agreement or order form containing material license
terms and the shipment of the media in which the criteria are embedded and
recognized ratably over the initial term of the license, typically one year.
Revenues from license renewals are received and deferred on the anniversary date
as provided in the agreement, unless prior notice of cancellation is received,
and are recognized ratably over the term of the renewal, typically one year.
Revenues from professional services, including installation, consulting and
training services, are recognized when the services are performed. Billings made
in advance of a service are deferred until the service is performed. Revenues
from credentialing services are recognized as such services are performed.

RESULTS OF OPERATIONS--THREE MONTH PERIOD COMPARISON
 
    REVENUES.  Revenues consist of revenues from the licensing of Criteria and
professional services. Revenues increased from $3.5 million during the three
months ended March 31, 1997 to $5.3 million, or 51.4%, during the three months
ending March 31, 1998.
 
    Revenues from licensing of Criteria increased from $3.1 million during the
first quarter of fiscal 1997 to $5.1 million, or 64.5%, during the first quarter
of 1998, as the Company experienced continued demand for its products.
 
    Revenues from professional services were $264,000 in the first quarter of
1998, a decrease of $136,000 from revenues of $400,000 in the first quarter of
1997. The reduction is a result of decreased credentialing revenues of $82,000,
and reduced consulting services and professional services.
 
    COST OF SALES.  Cost of sales increased from $946,000 in the first quarter
of 1997 to $1,259,000 in the first quarter of 1998, an increase of $313,000. The
increase was a result of higher Criteria production costs of $107,000, a result
of the increase in licensed criteria products and increased payroll expense.
Cost of sales as a percentage of revenues decreased from 27.3% in the first
quarter of 1997 to 23.6% in the first quarter of 1998. The decrease is a result
of the expansion of Criteria licenses, which require a lower cost basis than
professional services.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses were $531,000,
or 15.4% of revenues and $889,000, or 16.7% of revenues during the first quarter
of 1997 and 1998, respectively. The increase in expenses is a result of higher
commissions and increased headcount of eleven employees.
 
                                      112

    PRODUCT DEVELOPMENT EXPENSES.  Product development expenses were $662,000,
or 19.1% of revenues and $1,244,000, or 23.3% of revenues during the first
quarter of 1997 and 1998, respectively. The increase was due to fifteen
headcount additions and outside service expenses in both clinical development
and technical development.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
were $1,039,000 and $1,540,000, or 30.0% and 28.9% of revenues during 1997 and
1998, respectively. The increase was a result of increased depreciation,
occupancy cost, and payroll expense.
 
RESULTS OF OPERATIONS--FISCAL YEAR COMPARISON
 
    REVENUES.  Total revenues increased from $10.7 million in 1996 to $16.3
million in 1997 representing an increase of $5.6 million, or 52.3%. Revenues
from licenses increased 57.3% and revenues from services increased 21.0%.
Revenues derived from new Criteria licenses increased as a result of refocusing
InterQual's sales and marketing efforts toward new client attainment. Revenues
from support services increased due to higher credentialing revenue. Total
revenues increased from $6.8 million in 1995 to $10.7 million in 1996, an
increase of $3.9 million or 57.4%. Revenues from licenses increased 111.5% while
revenue from services decreased 35.4%. The decrease in services revenue was a
consequence of a continuing evolution of InterQual away from consulting towards
its Criteria licensing model.
 
    COST OF SALES.  Cost of sales increased from $3.3 million in 1996 to $4.6
million in 1997, an increase of $1.3 million. Cost of sales for InterQual
comprise all expenses associated with customer support, client services and
credentialing. These include all salaries, commissions and benefits, personnel
and office costs, expenses associated with producing and dispatching criteria
sets and an allocated facility expense. The increase was a result of increased
payroll and increased Criteria production materials as a result of the increased
number of new and renewal licenses over the prior period. Cost of sales
decreased from $3.6 million in 1995 to $3.3 million in 1996, a decrease of 8.7%.
The reduction was a function of the lower revenues being generated from
consulting and therefore a decrease in the costs being incurred by professional
services and a decrease in employee count in the professional services group by
three.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses increased from
$1.9 million in 1996 to $2.8 million in 1997, an increase of 43.2%. InterQual
primarily markets and sells Criteria licenses through a direct sales group.
Sales and marketing expenses include the salaries, commissions and benefits paid
to the regional license managers (RLMs), salaries and benefits of other sales
and marketing staff and related marketing and promotional activities. RLMs
receive commissions for sales to new customers and for selling additional
licenses to existing customers. Payroll and commission expense increased due to
higher revenues and an increase in employees. InterQual expanded marketing
efforts with additional promotional materials and criteria conferences, and
established an Alliance Partner Program. Sales and marketing expenses increased
from $947,000 in 1995 to $1.9 million in 1996, an increase of 104.9%. The
primary reason for this increase was the addition of ten sales and marketing
staff members in 1996.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development costs increased
from $1.8 million in 1996 to $3.3 million in 1997, an increase of $1.5 million.
Product development expenses comprise the costs associated with technical
development and clinical development. Technical development costs increased as
InterQual continued to develop automated delivery systems for its clinical
content. Clinical development costs increased as InterQual accelerated
development of its IWC (Indications for Workers' Compensation Clinical
Management) and IPS (Indications for Primary and Specialty Care Management)
criteria products. Product development costs increased from $674,000 in 1995 to
$1.8 million in 1996, an increase of 167.7%. Product development expenses
comprise the costs associated with technical development and criteria
development. The increase was a function of the development of AutoBook2 which
was released in November 1996 and two new criteria products. The IWC
(Indications for Workers' Compensation Clinical Management) criteria product was
developed throughout the first two quarters of 1996 and was released in July
1996. The IPS (Indications for Primary and Specialty Care Management) criteria
product was

developed in the later part of 1996 and was released in April 1997. Six new
employees were added to the product development department during 1996.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased from $3.5 million in 1996 to $4.9 million in 1997. The increase in
expenses was the result of additional bonus amounts, depreciation, legal costs
and the expansion of infrastructure overhead. General and administration
expenses increased from $2.4 million in 1995 to $3.5 million in 1996, an
increase of 44.5%. The increase is a function of the addition of new employees
which resulted in increased payroll and expenses associated with office
supplies, computer equipment and other facilities' expenses.
 
    INTEREST INCOME/EXPENSE.  Interest expense in 1995, 1996 and 1997 was
incurred on amounts due on a commercial loan and two auto loans.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    InterQual has financed its operations and capital requirements primarily
from revenue from operations, debt and capital leases.
 
    Cash and cash equivalents increased from $1.5 million at December 31, 1997
to $1.7 million at March 31, 1998, an increase of $200,000.
 
    On December 11, 1997 InterQual completed an amendment to a credit agreement
which increased the credit facility limit to $2 million, subject to certain
covenants. Interest is due and payable monthly at the lender's prime rate of
interest. Currently there are no draw-downs against such facility.
 
    Accounts receivable increased from $4.5 million at December 31, 1997 to $5.3
million at March 31, 1998 due to increased revenue and decreased cash
collections.
 
    In 1997 InterQual retired all outstanding amounts due on a line of credit of
$200,000, retired a note payable instrument of $102,000 and retired loans to
officers in the amount of $196,000. InterQual has long-term debt with
outstanding balances of $68,000 at March 31, 1998. InterQual has purchased
approximately $293,000 of property and equipment, $127,000 of which was expended
for the establishment of a training facility.
 
    InterQual believes its sources of liquidity and capital resources will be
sufficient to fund operating, investing and financing activities during 1998.*
 
    InterQual adopted SFAS 128, which was required to be adopted on December 15,
1997. This statement establishes standards for computing and presenting basic
and diluted earnings per share. Under this statement, basic earnings or loss per
share is computed by dividing the net earnings or loss by the weighted average
number of shares of common stock outstanding. Diluted earnings or loss per share
is determined by dividing the net earnings or loss by the sum of (1) the
weighted average number of common shares outstanding, (2) if not anti-dilutive,
the effect of outstanding stock options determined utilizing the treasury stock
method.

                          DESCRIPTION OF CAPITAL STOCK
 
DESCRIPTION OF ACCESS HEALTH CAPITAL STOCK
 
    As of May 15, 1998, the authorized capital stock of Access Health consisted
of 75,000,000 shares of Common Stock, $0.001 par value, and 5,000,000 shares of
Preferred Stock, $0.001 par value.
 
    ACCESS HEALTH COMMON STOCK.  As of May 15, 1998, there were approximately
18,993,742 shares of Access Health Common Stock outstanding held of record by
approximately 689 stockholders. Access Health Common Stock is listed on Nasdaq
under the symbol "ACCS." Holders of Access Health Common Stock are entitled to
one vote per share on all matters to be voted upon by the stockholders, except
that holders of Access Health Common Stock may cumulate votes in the election of
directors, so long as the names of the director or directors for whom such
holder intends to cumulate votes has been placed in nomination prior to the
voting and the stockholder, or any other holder of Access Health Common Stock,
has given notice at the meeting prior to the voting of the intention to cumulate
votes. The holders of Access Health Common Stock are entitled to receive ratably
such dividends, if any, as may be declared from time to time by the Access
Health Board out of funds legally available therefor. In the event of a
liquidation, dissolution or winding up of Access Health, the holders of Access
Health Common Stock are entitled to share ratably in all assets remaining after
payment of liabilities. The Access Health Common Stock has no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions applicable to the Access Health Common Stock. All
outstanding shares of Access Health Common Stock are fully paid and
non-assessable, and the shares of Access Health Common Stock to be outstanding
upon completion of the Merger will be fully paid and non-assessable.
 
    PREFERRED STOCK.  The Board of Directors of Access Health has the authority
to issue up to 5,000,000 shares of Preferred Stock in one or more series and to
fix the rights, preferences, privileges and restrictions granted to or imposed
upon any unissued and undesignated shares of Preferred Stock and to fix the
number of shares constituting any series and the designations of such series,
without any further vote or action by the stockholders. Although it presently
has no intention to do so, the Access Health Board, without stockholder
approval, can issue Preferred Stock with voting and conversion rights which
could adversely affect the voting power or other rights of the holders of Access
Health Common Stock. The issuance of Preferred Stock may have the effect of
delaying, deferring or preventing a change in control of Access Health. Access
Health has no present plans to issue Preferred Stock.
 
    Of the 5,000,000 shares of undesignated Preferred Stock of Access Health,
100,000 shares have been designated as Series A Participating Preferred Stock
(the "Series A Preferred Stock"), none of which is issued and outstanding. The
Series A Preferred Stock was designated in connection with the adoption of a
preferred shares rights agreement dated March 12, 1997 and is described in
Access Health's Registration Statement on Form 8-A dated March 13, 1997 pursuant
to which such preferred shares rights agreement is filed as an exhibit thereto.
 
    REGISTRATION RIGHTS.  Upon the Effective Time of the Merger, Access Health
has agreed to enter into the Registration Rights Agreement which will provide
certain rights with respect to the registration of the shares of Access Health
Common Stock received by InterQual Holders in the Merger. Under the Registration
Rights Agreement, the InterQual Holders may demand that Access Health file up to
two registration statements under the Securities Act with respect to the
underwritten public offerings of their shares at any time beginning after the
date Access Health has published the combined financial results of Access Health
and InterQual for a period of at least 30 days of combined operations. Such
demand registrations must be for an offering of shares of Access Health Common
Stock having an aggregate value of at least $25 million, net of underwriting
discounts and commissions. This demand registration right is subject to certain
exceptions and limitations including Access Health's right to delay an offering
under certain conditions and the right of the underwriters of an offering to
limit the number of shares included in a registration to up to 50% of the total
number of shares to be registered; provided that after the InterQual Holders
have sold an aggregate of two million shares of Access Health Common Stock
pursuant to the Registration Rights Agreement, the underwriters may limit the
number of shares to be registered without
 
                                      121
<PAGE>
regard to the Underwriters' Cutback. In addition, if Access Health proposes to
register any of its securities under the Securities Act for its own account or
the account of any of its stockholders, the InterQual holders are entitled to
notice of such proposed registration and to Piggyback Registration Rights,
subject to certain conditions and limitations including the Underwriters'
Cutback.
 
    The registration rights described above (i) will terminate as to any holder
at such time as such holder may sell all his or her shares using the 1% volume
limitation pursuant to Rule 144 under the Securities Act and (ii) may not be
exercisable by a holder at such time as a holder could sell all his or her
shares in a three month period using the average weekly trading volume
limitation pursuant to Rule 144 under the Securities Act, provided that each
holder's Piggyback Registration Rights shall not be suspended until such holder
is able to sell all of his or her shares in a three month period in compliance
with Rule 144 but using 50% of the Rule 144 average weekly trading volume
limitation.
 
    In addition, pursuant to the Merger Agreement, certain InterQual Holders
will be granted shelf registration rights permitting the resale pursuant to Rule
415 under the Securities Act under this proxy and registration statement of up
to one million shares of Access Health Common Stock in the open market at any
time beginning as early as the date that combined financial results for 30 days
have been released by Access Health and InterQual, with such sale to take place
through no more than two transactions of at least 250,000 shares per
transaction. In connection with the closing of the Merger, the Company intends
to file a registration statement on Form S-3 to register for resale pursuant to
Rule 415 under the Securities Act all such shares that are not resold under this
proxy and registration statement pursuant to the Holders' shelf registration
rights. Under the Registration Rights Agreement, the shelf registration rights
may be suspended under certain conditions upon the request of Access Health or
the managing underwriters of a public offering of Access Health's Common Stock.
The shelf registration rights expire one year after the Closing Date, or earlier
in the event the InterQual Holders holding such rights achieve certain liquidity
thresholds. Access Health will pay all registration expenses for any
registration pursuant to the Registration Rights Agreement, but the InterQual
Holders included in such registrations must bear their proportionate share of
all selling expenses.
 
    In addition, on November 18, 1996, Access Health entered into another
registration rights agreement with certain stockholders (the "1996 Registration
Rights Agreement"). Under the 1996 Registration Rights Agreement, if Access
Health proposes to register any of its securities under the Securities Act, the
holders are entitled to notice of such proposed registration and the opportunity
to include their shares therein, subject to certain conditions and limitations
including the right of the underwriters of an offering to limit the number of
shares included in such registration to 35% of the total number of shares to be
registered in certain circumstances. Access Health will pay all registration
expenses for such registration, but the holders included in such registration
must bear their proportionate share of all selling expenses. The holders may
also require that Access Health file up to three registration statements under
the Securities Act with respect to underwritten public offerings of their shares
at any time. The holders must bear all registration and selling expenses
incurred in connection with such registration. The registration rights under the
1996 Registration Rights Agreement (i) will terminate as to any holder at such
time as such holder may sell all his or her shares using the 1% volume
limitation pursuant to Rule 144 under the Securities Act and (ii) may not be
exercisable by a holder at such time as a holder could sell all his or her
shares in a three month period using the average weekly trading volume
limitation pursuant to Rule 144 under the Securities Act. The 1996 Registration
Rights Agreement is still effective, but currently the ability of the holders to
exercise their rights under such agreement has been suspended pursuant to the
terms of the agreement. Under certain circumstances, the holders' rights under
the 1996 Registration Rights Agreement may be revised.
 
    DELAWARE GENERAL CORPORATION LAW SECTION 203.  As a corporation organized
under the laws of the State of Delaware, Access Health is subject to Section 203
of the DGCL which restricts certain business combinations between Access Health
and an "interested stockholder" (in general, a stockholder owning 15% or more of
Access Health's outstanding voting stock) or its affiliates or associates for a
period of three years following the date on which the stockholder becomes an
"interested stockholder." The restrictions
 
                                      122
<PAGE>
do not apply if (i) prior to an interested stockholder becoming such, the Access
Health Board approves either the business combination or the transaction in
which the stockholder becomes an interested stockholder, (ii) upon consummation
of the transaction in which any person becomes an interested stockholder, such
interested stockholder owns at least 85% of the voting stock of Access Health
outstanding at the time the transaction commences (excluding shares owned by
persons who are both directors and officers of Access Health) or (iii) on or
subsequent to the date an interested stockholder becomes such, the business
combination is both approved by the Access Health Board and authorized at an
annual or special meeting of Access Health's stockholders, not by written
consent, but by the affirmative vote of at least 66 2/3% of the outstanding
voting stock not owned by the interested stockholder.
 
    TRANSFER AGENT AND REGISTRAR.  The Transfer Agent and Registrar for the
Access Health Common Stock is The First Chicago Trust Company of New York.
 
DESCRIPTION OF INTERQUAL CAPITAL STOCK
 
    As of February 28, 1998, the authorized capital stock of InterQual consisted
of 200,000 shares of authorized Common Stock, $1.00 par value, of which 100,000
shares are designated InterQual Class A Common Stock and 100,000 shares are
designated InterQual Class B Common Stock.
 
    As of February 28, 1998, there were 10,000 shares of InterQual Class A
Common Stock issued and outstanding and no shares of InterQual Class B Common
Stock outstanding. There are 1,922 shares of InterQual Class B Common Stock
subject to options that will vest and become exercisable in accordance with
their terms immediately prior to the Effective Time. Holders of InterQual Class
A Common Stock and holders of InterQual Class B Common Stock are equal in all
respects, except that holders of InterQual Class A Common Stock are entitled to
one vote per share on all matters to be voted upon and holders of InterQual
Class B Common Stock are not entitled to vote on any matter. The vote of the
stockholders on all matters is determined by the vote of a majority of all of
the issued and outstanding shares of InterQual Class A Common Stock represented
at a meeting of stockholders. All outstanding shares of InterQual Capital Stock
are fully paid and non-assessable.
 
                COMPARISON OF RIGHTS OF HOLDERS OF ACCESS HEALTH
              COMMON STOCK AND HOLDERS OF INTERQUAL CAPITAL STOCK
 
    The rights of Access Health stockholders are governed by the Access Health
Certificate of Incorporation, the Access Health Bylaws and the laws of the State
of Delaware. The rights of InterQual's stockholders are governed by the
InterQual Certificate of Incorporation, the InterQual Bylaws and the laws of the
State of Delaware. After the effective time of the Merger, the rights of
InterQual stockholders who become Access Health stockholders will be governed by
the Access Health Certificate of Incorporation, Access Health Bylaws and the
laws of the State of Delaware. In most respects, the rights of Access Health
stockholders and InterQual stockholders are similar. The following discussion of
certain similarities and material differences between the rights of Access
Health stockholders and the rights of InterQual stockholders under their
respective Certificates of Incorporation and Bylaws is only a summary of certain
provisions and does not purport to be a complete description of such
similarities and differences. The following discussion is qualified in its
entirety by reference to the laws of the State of Delaware and the full texts of
the respective Certificates of Incorporation and Bylaws of Access Health and
InterQual. Copies of such documents may be obtained from Access Health and
InterQual, as the case may be, and such documents of Access Health are
incorporated by reference as exhibits to the Registration Statement of which

    Upon consummation of the Merger, the holders of InterQual Capital Stock will
become holders of Access Health Common Stock. Appraisal rights are available to
stockholders of InterQual with respect to the Merger. See "Approval of the
Merger and Related Transactions--Delaware Appraisal Rights."
 
    In addition, certain other rights and privileges of InterQual stockholders
will change as a result of the Merger. Upon completion of the Merger, the
percentage ownership of Access Health by each former
 
                                      123
<PAGE>
InterQual stockholder will be substantially less than his, her or its current
percentage ownership of InterQual. Accordingly, former InterQual stockholders
will have a significantly smaller voting influence over the affairs of Access
Health than they currently enjoy over the affairs of InterQual. Moreover,
certain contractual rights presently possessed by holders of InterQual Capital
Stock will cease to exist after the Merger. Specifically, the obligation to
offer any shares to be transferred in any manner to the other stockholders, the
associated right of first refusal on such offered shares to transferred by the
other stockholders, and other rights unique to the organization and financing of
InterQual will terminate at the Effective Time.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Access Health, Inc.
 
    We have audited the accompanying consolidated balance sheets of Access
Health, Inc. as of September 30, 1996 and 1997, and the related consolidated
statements of operations, mandatorily redeemable convertible preferred stock and
stockholders' equity, and cash flows for the three years in the period ended
September 30, 1997. Our audits also included the financial statement schedule
listed in the Index at Item 14(a)2. These financial statements and schedule are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits. In November 1996,
the Company completed a merger with Informed Access Systems, Inc. ("Informed
Access") in a transaction that was accounted for as a pooling-of-interests. We
did not audit the 1995 financial statements of Informed Access, a wholly-owned
subsidiary, which statements reflect aggregate revenues constituting
approximately 8% of the related consolidated financial statements total for
1995. Those statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to data included for
Informed Access is based solely on the report of the other auditors.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for our opinion.
 
    In our opinion, based on our audits and report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the consolidated financial position of Access Health, Inc. at
September 30, 1996 and 1997, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended September 30,
1997, in conformity with generally accepted accounting principles. Also, in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Informed Access Systems, Inc.
 
    We have audited the accompanying consolidated balance sheet of INFORMED
ACCESS SYSTEMS, INC. (a Delaware corporation) and subsidiary as of December 31,
1995, and the related consolidated statements of operations, mandatorily
redeemable convertible preferred stock and stockholders' deficit and cash flows
for the year then ended, not presented separately herein. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financials statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above, not presented
separately herein, present fairly, in all material aspects, the financial
position of Informed Access Systems, Inc. and subsidiary as of December 31,
1995, and the results of their operations and their cash flows for the year then
ended, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               SEPTEMBER 30, 1997
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION, BUSINESS AND PRINCIPLES OF CONSOLIDATION
 
    The accompanying consolidated financial statements include the accounts of
Access Health, Inc. and its wholly-owned subsidiaries. The consolidated entity
is referred to herein as the Company. All intercompany accounts and transactions
have been eliminated in consolidation. As more fully described in Note 2, during
November 1996, the Company entered into business combinations within Informed
Access Systems, Inc., ("Informed Access") and Clinical Reference Systems, Ltd.,
("CRS"). The business combinations have been accounted for as
poolings-of-interests and the historical consolidated financial statements of
the Company for all dates and periods prior to the business combinations have
been restated to include the financial positions, results of operations and cash
flows of Informed Access and CRS.
 
    The Company develops, markets and supports care management programs which
help managed care organizations, self-insured employers and hospitals manage
consumer demand for health care services.
 
REVENUE RECOGNITION
 
    Revenues include care management services, which consist of program
membership, member communications and teleservicing fees from the Company's
Personal Health Advisor-Registered Trademark-, FirstHelp-TM- and ASK-A-
NURSE-Registered Trademark- contracts with managed care organizations,
self-insured employers and hospitals. Revenues also include licensing and
support services related to the Company's ASK-A-NURSE-Registered Trademark-,
Cancer HELPLINK-Registered Trademark-, FirstHelp-TM-, Access Care Management
System-SM-, and HealthSelect and patient education software products.
 
    Program membership fees from Personal Health Advisor-Registered Trademark-
and FirstHelp-TM- contracts are recognized ratably in accordance with contract
terms on the basis of per-member fees. Member communications fees are recognized
upon the delivery of services. Teleservicing fees are recognized in accordance
with contract terms on the basis of per-call fees or fees based on phone
counselor staffing.
 
   
    License revenues from ASK-A-NURSE-Registered Trademark-, Cancer
HELPLINK-Registered Trademark-, FirstHelp-TM- and ACMS-SM- are recognized
ratably over the term of the contract. During fiscal 1995, revenues from
ASK-A-NURSE-Registered Trademark- and Cancer HELPLINK-Registered Trademark- were
recognized when implementation services were substantially complete, no
significant continuing obligations remained and collection was probable. Fees
billable more than one year after the license grant date are discounted at the
prime rate (which ranged from 6% to 9% for the periods presented), plus 3%.
HealthSelect and patient education software revenue is recognized upon delivery
of the software.
    
 
    Support revenues are comprised of software support revenue and direct
marketing fees. Revenue from support contracts and software maintenance
contracts is deferred when billed and recognized ratably over the contract term.
Direct marketing fees are recognized upon the delivery of services.
 
PRODUCT AND OTHER DEVELOPMENT COSTS
 
    Product and other development costs are expensed as incurred and consist
primarily of salaries, supplies and contract services related to the development
of the Company's products and services.

                               SEPTEMBER 30, 1997
 
NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CASH EQUIVALENTS AND AVAILABLE-FOR-SALE SECURITIES
 
    The Company invests its excess cash in high quality money market instruments
and certain other investments. The Company considers highly liquid investments
with maturities of three months or less to be cash equivalents.
Available-for-sale securities are recorded at amounts which approximated fair
value as of September 30, 1996 and 1997 and are available to fund current
operations.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost and consist of office furniture
and equipment, computer equipment, leasehold improvements and computer software
for internal use. Depreciation and amortization of furniture and equipment,
computer equipment and leasehold improvements are provided on the straight line
basis over the useful lives of the respective assets or the lease term if
shorter, which range from two to ten years. Computer software consists of the
direct cost of internally-developed software and purchased software and is being
amortized on the straight-line basis over an estimated useful life of four
years.
 
PURCHASED INTANGIBLE ASSETS
 
    Purchased intangible assets consist primarily of product rights and are
being amortized on the straight-line basis over three to ten years.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
    The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable from future undiscounted cash flows. Impairment losses are
recorded for the difference between the carrying value and fair value of the
long-lived asset.
 
INTERESTS IN AHN
 
    In April 1996, the Company invested $5.0 million in America's Health
Network, L.P. ("AHN"), a new 24-hour 7 days a week cable television channel
devoted to consumer health care information. The Company is a limited partner in
AHN. In 1996 the investment in AHN was accounted for using the cost method.
During January 1997 the Company purchased an 8% Convertible Subordinated
Debenture from AHN in the face amount of $5.0 million. The debenture, which
matures on December 31, 2001, is unsecured an subordinated to all other debt
owed by AHN. Interest accrues at 8% annually and is only payable under certain
conditions as described in the agreement. The debenture is convertible into
partnership interests at the option of the holder.
 
    During fiscal 1997, AHN's majority owner and principal financial sponsor,
The Providence Journal Company ("PJC") was acquired by AH Belo Corp ("Belo").
Subsequent to Belo's acquisition of PJC in February 1997, Belo indicated that it
did not intend to provide additional financing to AHN and pursued alternate
financing and operating strategies for AHN. On July 31, 1997, Belo terminated
its 65 percent ownership interest in AHN when a previously announced agreement
to sell its interest in AHN to Columbia/HCA Healthcare Corp. ("Columbia") was
terminated in late July when Columbia failed to close on the transaction. As a
result of losing its principal financial sponsor and not being able to obtain

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
additional financing, AHN suspended daily operations and furloughed the majority
of its employees. Accordingly, the Company determined the equity investment and
the subordinated debenture were not recoverable and they were written off in the
fourth quarter of fiscal 1997.
 
CONCENTRATIONS OF CREDIT RISK AND MAJOR CUSTOMERS
 
    During fiscal 1997, sales to each of the Company's three largest customers
were $8,348,000, $8,180,000 and $7,157,000, respectively. During fiscal 1996,
sales to each of the Company's three largest customers were $10,446,000,
$7,472,000 and $7,184,000, respectively.
 
    The Company's accounts and licenses receivable are primarily with companies
in the health care and insurance industries. The Company provides for
uncollectible accounts and licenses receivable and such amounts have been
recorded in accordance with the Company's estimates.
 
STOCK SPLIT
 
    On February 15, 1996, the Company effected a three-for-two common stock
split. All references in the accompanying financial statements to the number of
common shares and per-share amounts have been retroactively restated to reflect
the stock split.
 
NET INCOME (LOSS) PER SHARE
 
    The Company's net income (loss) per share is based upon the weighted average
number of shares of common stock outstanding. Common stock issuable upon the
exercise of stock options and stock warrants has been included in the
computation, to the extent dilutive, using the treasury stock method.
 
INCOME TAXES
 
    Deferred income tax assets and liabilities are determined based on
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the currently enacted tax rates and laws that
are scheduled to be in effect when the differences are expected to reverse.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The Company's financial instruments consist of cash and equivalents,
available-for-sale securities, and long-term debt. The carrying values of cash
and equivalents and available-for-sale securities approximate fair value. The
fair value of long-term debt is estimated based on current rates available for
similar debt with similar maturities and securities, and at September 30, 1996
and 1997, approximates the carrying value.
 
STOCK ISSUED TO EMPLOYEES
 
    As permitted under the provisions of Financial Accounting Standards No. 123
"Accounting for Stock Based Compensation" ("SFAS 123"), the Company has elected
to account for stock-based compensation using the intrinsic value method
prescribed by Accounting Principles Board's Opinion No. 25 "Accounting for Stock
Issued to Employees" ("APB 25"). Under the intrinsic value method, compensation
cost is the

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
excess, if any, of the quoted market price or fair value of the stock at the
grant date or other measurement date over the amount an employee must pay to
acquire the stock.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates may affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities at the date of the
financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
RECLASSIFICATIONS
 
    Certain reclassifications have been made to amounts reported as of and for
the years ended September 30, 1995 and 1996 to conform with the September 30,
1997 presentation.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 128
 
    In February 1997 the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share," which is
required to be adopted on December 31, 1997. At that time, the Company will be
required to change the method currently used to compute net income (loss) per
share and to restate all prior periods. Under the new requirements for
calculating primary net income (loss) per share, the dilutive effect of stock
options will be excluded. The impact of adopting the new pronouncement is
expected to result in an increase in basic net income (loss) per share for the
years ended September 30, 1996 and 1997 of $.007 and $.022 per share,
respectively.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 130
 
    In June 1997 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income," which
is required to be adopted for fiscal years beginning after December 15, 1997.
This statement establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
This statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income to be reported in a
financial statement that is displayed with the same prominence as other
financial statements. Reclassification of financial statements for earlier
periods provided for comparative purposes is required. Management has determined
this change will not significantly affect its financial reporting. The Company
expects to adopt Statement No. 130 in the first quarter of fiscal 1999.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 131
 
    In June 1997 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information," effective for fiscal years beginning after
December 15, 1997. The statement requires that a public company report financial
and descriptive information about its reportable operating segments using the
management

approach. Management has determined this change will not significantly affect
its financial reporting. The Company expects to adopt Statement No. 131 in the
first quarter of fiscal 1999.
 
NOTE 2: BUSINESS COMBINATIONS
 
    During November 1996, the Company completed mergers with Informed Access in
exchange for 5,375,000 shares of Access Health Common Stock (including 4,778,317
shares issued to Informed Access shareholders and 596,683 shares reserved for
future grant to Informed Access option holders) and CRS, in exchange for 170,000
issued shares of Access Health common stock. These business combinations were
accounted for as pooling-of-interests and, accordingly, the historical financial
statements of the Company have been restated to include the consolidated
financial statements of Access Health, Informed Access and CRS for all dates and
periods presented.
 
    The consolidated statements of operations and accompanying notes of the
Company for the fiscal year ended September 30, 1995 include the operations of
Informed Access and CRS for the calendar year ended December 31, 1995. The
consolidated statement of operations and accompanying notes of the Company for
the fiscal year ended September 30, 1996 include the operations of Informed
Access and CRS for the twelve months ended September 30, 1996. Accordingly, the
Company's accumulated deficit has been adjusted for the effect of utilizing
differing fiscal year ends for these periods. The combined revenues and net
income (loss) of Informed Access and CRS for the three months ended December 31,
1995 were $1,800,000 and $(128,000), respectively. Subsequent to the business
combinations, the fiscal year-ends of Informed Access and CRS have been changed
from December 31 to September 30 to conform to the fiscal year end of Access
Health.
 
    The table below sets for the combined revenues and net income (loss) for the
years ended September 30, 1995 and 1996 (in thousands):

    The adjustments to the combined results of operations included in the table
above reflect the realization of the Informed Access net operating loss

will reverse in periods subsequent to the merger.
 
    Integration and restructuring costs related to the mergers of Informed
Access and CRS were recorded in the amounts of $7.0 million and $2.7 million
during the first and fourth quarters of fiscal 1997, respectively. Integration
and restructuring costs include: $7.1 million for severance, outplacement and
relocation costs specifically related to the merger; $1.2 million related to the
closure and elimination of duplicate leased facilities, primarily corporate
headquarters, a sales office and a call center; and $1.3 million related to the
write-off of computer hardware and other assets which were made obsolete as a
result of

the merger and duplicate information systems. The remaining merger-related
accrual at September 30, 1997 was approximately $3.1 million. Total expected
cash expenditures relating to the merger charge are estimated to be
approximately $6.7 million, of which approximately $3.6 million was disbursed
prior to September 30, 1997. Termination benefits received by employees
terminated through September 30, 1997 were approximately $4.5 million. The
remaining severance and outplacement amounts are expected to be paid within the
next twelve months.

    Notes payable to related parties are comprised of notes payable arising from
bonuses to members of management who are also stockholders of the Company, and
are due January 1998.
 
NOTE 6: LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS
 
    The Company has a term facility agreement (the "Term Agreement") whereby
through December 1996 the Company could borrow, in one or more borrowings, an
amount not to exceed $2.0 million in the aggregate, subject to certain
conditions set forth in the Term Agreement. This commitment is in the form of a
$680,000 note payable facility and a $1,320,000 capital lease facility. At
September 30, 1997, cumulative borrowings under the note payable facility and
capital lease facility aggregated $395,000 and $676,000, respectively (at
September 30, 1996, borrowings under the note payable facility and capital lease
facility were $591,000 and $953,000, respectively). Borrowings under the Term
Agreement are secured by certain of the Company's equipment with a net book
value of approximately $1,200,000 at September 30, 1997.
 
    Amounts payable under the Term Agreement bear interest at 14.48%, are due at
varying dates through September 1999, and require monthly payments of principal
and interest totaling approximately $52,000. Amounts due under the note payable
facility of the Term Agreement are $198,000 and $197,000 in fiscal 1998 and
1999, respectively.
 
    In connection with the Term Agreement, the Company issued warrants to the
lender in October 1995 and May 1996. The warrants were converted into warrants
to purchase common stock as a result of the merger (Note 2). The warrants were
converted into 8,638 shares of common stock in 1997.
 
    The Company has other capital leases outstanding aggregating $262,000 at
September 30, 1997 ($399,000 at September 30, 1996).

NOTE 7: INCOME TAXES (CONTINUED)
    Income tax payments were $50,000, $4,908,900 and $1,199,000 for the years
ended September 30, 1995, 1996 and 1997, respectively. The Company received
income tax refunds totaling $1,629,658 during the year ended September 30, 1995.
 
    During 1997, the Company liquidated one of its subsidiaries, resulting in
the ability to utilize the net operating loss and reduce the valuation allowance
by $3,368,000. The Company has a state net operating loss carry forward of
approximately $6,700,000 which expires between 2007 and 2011. The Company also
has approximately $161,000 of federal research and development credits which
expire between 2007 and 2011.
 
    Realization of the Company's net deferred tax assets is dependent upon the
Company generating sufficient taxable income in future years in appropriate tax
jurisdiction to obtain benefit from the reversal of temporary differences and
from tax credit carryforwards. The amount of deferred tax assets considered
realizable is subject to adjustment in future periods if estimates of future
taxable income are reduced.
 
NOTE 8: COMMITMENTS

NOTE 9: STOCKHOLDERS' EQUITY
 
COMMON STOCK
 
    In December 1995, the Company completed a secondary public offering of its
common stock. A total of approximately 4.8 million shares were sold at $21.33
per share of which 1.5 million shares were sold by the Company and approximately
3.3 million shares were sold by certain of the Company's original Access Health,
Inc. venture capital stockholders. Net proceeds to the Company from the offering
were approximately $29.5 million.
 
MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED STOCK
 
    Informed Access was authorized to issue shares of mandatorily redeemable
preferred stock from time to time in one or more series of designations, rights,
preferences and limitations established by its board of directors. As of
September 30, 1996, 3,734,151 aggregate shares of Series A, B, and C mandatorily
redeemable preferred stock were issued and outstanding. Each share of
mandatorily redeemable preferred stock was converted into one share of common
stock upon completion of the merger (Note 2).
 
STOCK OPTIONS
 
    At September 30, 1997, the Company has four stock-based compensation plans,
which are described below. The Company has elected to follow Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employee" (APB
25) and related Interpretations in accounting for its employee stock

NOTE 9: STOCKHOLDERS' EQUITY (CONTINUED)
options because, as discussed below, the alternative fair value accounting
provided for under FASB Statement No. 123, "Accounting for Stock-Based
Compensation," requires use of option valuation models that were not developed
for use in valuing employee stock options.
 
    EMPLOYEE OPTIONS
 
    The Company established an employee common stock option plan in 1989 (the
"1989 Plan") under which incentive stock options, nonqualified stock options,
and restricted common stock may be issued or sold to employees and consultants.
As of September 30, 1997 a total of 3,550,000 shares of common stock have been
reserved for issuance under these plans, of which 127,647 shares remained
available for the granting of options at September 30, 1997.
 
    Incentive stock options generally become exercisable at the rate of twenty
percent per year commencing on the first anniversary of the date of grant. As of
September 30, 1996 and 1997, options to purchase 330,221 shares at exercise
prices ranging from $0.167 to $12.42 per share and 677,129 shares at exercise
prices ranging from $0.333 to $39.00 per share, respectively, were exercisable.
 
    During May and July 1996, certain options were granted with exercise prices
below the applicable fair market value (as determined by an independent
appraisal) on the date of grant, resulting in deferred stock compensation of
approximately $476,000. The deferred stock compensation was to be amortized into
expense ratably over the four year vesting term of the related options; however,
because such options became 100% vested as a result of the merger with Informed
Access in November 1996, the unamortized balance of deferred stock compensation
was recorded as an expense in the quarter ended December 31, 1996.
 
    On November 18, 1996, 739,500 options under the Informed Access employee
stock option plan converted to 596,593 Access Health Options. As of September
30, 1997, 297,055 shares were outstanding and 291,693 were exercisable at prices
ranging from $0.18 to $14.375 per share.
 
    DIRECTOR OPTIONS
 
    The Company established a director common stock participation plan in 1995
(the "1995 Director Stock Option Plan") under which nonqualified stock options
may be granted to directors. As of September 30, 1997, a total of 150,000 shares
of common stock have been reserved for issuance under this plan, of which 93,750
shares remained available for the granting of options at September 30, 1997. As
of September 30, 1997, options to purchase 56,250 shares were granted and 32,812
shares were exercisable at prices ranging from $10.25 to $54.25 per share.
 
    SUPPLEMENTAL PLAN
 
    The Company established a Supplemental Plan in fiscal 1997 (the
"Supplemental Plan") under which nonqualified stock options may be granted to
employees and consultants. As of September 30, 1997, a total of 1,000,000 shares
of common stock have been reserved for issuance under this Plan, of which
706,058 had been granted, 153,154 were cancelled and 447,096 were available for
grant. As of September 30, 1997, 5,000 were exercisable at prices ranging from
$14.375 to $33.125 per share.

NOTE 9: STOCKHOLDERS' EQUITY (CONTINUED)
    STOCK PURCHASE PLAN
 
    The Company established a stock purchase plan in 1991 (the "1991 Plan")
under which most employees of the Company may participate. A total of 825,000
shares of the Company's common stock have been reserved for issuance under the
1991 Plan. The 1991 Plan is administered by a committee appointed by the Board
of Directors. Employees can elect to have from 1% to 10% of their monthly gross
salary deducted during each offering period and applied to the purchase of
stock. The purchase price is an amount equal to 85% of the lower fair market
values of a share of common stock of the Company as of the beginning or end of
each six-month offering period. During the years ended September 30, 1995, 1996
and 1997, the Company sold 48,548 shares of common stock for $468,710, 41,659
shares of common stock for $753,146 and 42,272 shares of common stock for
$990,239, respectively. For purposes of calculating the pro forma disclosures
required by SAFS 123, the fair value of the employee's purchase rights was
estimated using the Black-Scholes option pricing model with the following
assumptions for the years ended September 30, 1996 and 1997: dividend yield of
0; expected life of 6 months; expected volatility of .722; and risk-free
interest rate of 5.70% for both periods. The weighted-average fair value of
those purchase rights granted during the years ended September 30, 1996 and
1997, was $7.61 and $12.33, respectively.
 
STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123 PRO FORMA DISCLOSURES
 
    Pro forma information regarding net income (loss) and net income (loss) per
share is required by SFAS 123, which also requires that the information be
determined as if the Company has accounted for its employee stock options
granted subsequent to October 1, 1995 under the fair value method of SFAS 123.
The fair value for these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following assumptions for fiscal
1996 and 1997: risk-free interest rate range of 5.70% to 6.05%; a dividend yield
of 0%; volatility factors of the expected market price of the Company's common
stock of .722; and an average expected life of the option of 3.3 years.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.
 
    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the vesting period. The Company's pro forma
information, which includes the stock option plans and the employee stock
purchase plan follows (in thousands except for per share information):

COMMON STOCK WARRANTS AND OPTIONS
 
    In October 1988, nonqualified stock options to purchase 98,974 shares of
Series A Preferred Stock at $0.46 per share, which converted to common stock
options on February 28, 1992, were granted to a former director. As of September
30, 1997, 96,617 shares of common stock have been issued pursuant to this
option.
 
    Nonqualified stock options to purchase 22,500 shares of common stock at
prices ranging from $4.167 to $6.667 per share were granted in fiscal 1993 to
certain consultants of the Company. The options become exercisable in equal
installments over a five-year period commencing on the first anniversary of the
date of grant; as of September 30, 1997, 15,000 shares of common stock have been
purchased pursuant to these options and 3,000 of the remaining 7,500 shares are
exercisable.
 
    In May 1996, the Company granted 2,000 shares of restricted stock to an
officer. The Company retained the right to repurchase, at the market price on
the date of grant ($50.625 per share), all of the shares if the officer left the
Company during the first year after the grant date and half of the shares if the
officer left the Company during the second year after the grant date. That
officer left the Company April 1, 1997, and all shares were vested pursuant to
agreement with such officer. The value of the shares, at the market price on the
date of grant ($50.625 per share), was charged to operations at that time.
 
    During 1996, the Company granted nonqualified stock options to purchase
230,000 shares of common stock at $50.625 per share to an officer. That officer
left the Company April 1, 1997. Pursuant to the separation agreement and
consistent with the option agreement, options for 92,000 shares become
exercisable in equal installments over a two-year period commencing on the first
anniversary of the date of grant. As of September 30, 1997, 46,000 shares are
exercisable through April, 1999. The remainder have been canceled.
 
    During 1997, the Company granted nonqualified stock options to purchase
33,000 shares of common stock at $14.375 per share to an officer. The options
will become exercisable in equal installments over a five-year period commencing
on the first anniversary of the date of grant. As of September 30, 1997, none of
the shares are exercisable.

NEW ACCOUNTING PRONOUNCEMENTS
 
    STATEMENT OF ACCOUNTING STANDARDS NO. 128
 
    During fiscal 1998, Access Health adopted SFAS 128. This statement
establishes standards for computing and presenting basic and diluted earnings
per share. Under this statement, basic earnings or loss per share is computed by
dividing the net earnings or loss by the weighted average number of shares of
common stock outstanding. Diluted earnings or loss per share is determined by
dividing the net earnings or loss by the sum of (1) the weighted average number
of common shares outstanding, (2) if not anti-dilutive, the number of shares of
convertible preferred stock as if converted upon issuance, and (3) if not anti-
dilutive, the effect of outstanding stock options determined utilizing the
treasury stock method.
 
    A reconciliation of the numerator and denominators used in computing per
share net income (loss) from continuing operations is as follows:

NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Options to purchase approximately 1.1 million shares of Access Health's
common stock were outstanding at March 31, 1997, but were not included in the
computation of diluted earnings per share because they were anti-dilutive.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 130
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income," which
is required to be adopted for fiscal years beginning after December 15, 1997.
This statement establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
This statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. Reclassification of financial statements for earlier
periods provided for comparative purposes are required. Management has
determined this change will not significantly affect its financial reporting.
The Company expects to adopt Statement No. 130 beginning in the first quarter of
fiscal 1999.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 131
 
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information," effective for fiscal years beginning after
December 15, 1997. This statement requires that a public company report
financial and descriptive information about its reportable operating segments
using the management approach. Management has determined this change will not
significantly affect its financial reporting. The Company expects to adopt
Statement No. 131 in the first quarter of fiscal 1999.
 
    STATEMENT OF POSITION 98-1
 
    In March 1998, the AICPA issued SOP 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use". This statement is
effective for fiscal years beginning after December 15, 1998, although earlier
application is permitted. In general, SOP 98-1 requires that certain costs to
develop software for internal use be capitalized. These requirements are to be
applied prospectively from the date of the Company's adoption. The Company
historically has not capitalized such costs.
 
NOTE 2: BUSINESS COMBINATIONS
 
    During November 1996, the Company consummated business combinations with
Informed Access which included the exchange of 5,375,000 shares of Access Health
common stock (including 4,778,317 shares issued to Informed Access shareholders
and 596,683 shares reserved for future grant to Informed Access option holders)
and CRS, which included the exchange of 170,000 shares of Access Health common
stock. These business combinations were accounted for as pooling-of-interests
and, accordingly, the historical financial statements of the Company have been
restated to include the consolidated financial statements of Access Health,
Informed Access and CRS for all periods presented.

NOTE 2: BUSINESS COMBINATIONS (CONTINUED)
    As of February 17, 1998, the Company announced a definitive agreement to
acquire privately held InterQual, Inc. of Marlborough, Massachusetts. Under the
terms of the acquisition, 4,290,000 shares of the Company's stock will be
exchanged for the outstanding shares of InterQual, Inc. The number of shares
issuable is subject to adjustment of up to an additional 500,000 shares to be
issued based upon a minimum transaction value of $130 million. It is anticipated
that the transaction would be accounted for as a pooling of interests under APB
Opinion No. 16 and is expected to close in the third fiscal quarter of this
year. The merger transaction is subject to stockholder approval by both
companies and customary closing conditions. The Company expects to recognize a
one-time charge in the third fiscal quarter of this year for integration and
transaction charges of approximately $8 to $9 million.
 
NOTE 3: NOTES PAYABLE TO RELATED PARTIES
 
    Notes payable to related parties arising from bonuses are payable to members
of management, who are also stockholders of the Company. The final installment
due was paid in January 1998.
 
NOTE 4: LONG-TERM DEBT
 
    The Company has a term facility agreement (the "Term Agreement") consisting
of note payable and capital lease facilities. At March 31, 1998, principal
balances under the note payable facility and capital lease facility totaled
$298,000 and $523,000, respectively. Principal balances under the Term Agreement
are secured by certain of the Company's equipment with an aggregate carrying
value of approximately $763,000 at March 31, 1998. Amounts payable under the
Term Agreement bear interest at 14.48%, are due at varying dates through
September 1999, and require monthly payments of principal and interest totaling
approximately $52,000. Payments due under the note payable facility of the Term

NOTE 5: INCOME TAXES
 
    The Company's state net operating loss carryforwards of approximately $6.7
million as of September 30, 1997 expire between 2007 and 2011. The Company also
has approximately $161,000 of federal research and development tax credits
available, which expire between 2007 and 2011.
 
    Realization of the Company's net deferred tax assets is dependent upon the
Company generating sufficient taxable income in future years in the United
States to obtain benefit from the reversal of temporary differences and from tax
credit and state net operating loss carryforwards. The amount of deferred tax
assets considered realizable is subject to adjustment in future periods if
estimates of future taxable income are reduced.
 
NOTE 6: COMMITMENTS

To the Stockholders of
  InterQual, Inc.:
 
    We have audited the accompanying balance sheets of InterQual, Inc. (a
Delaware corporation) as of December 31, 1996 and 1997, and the related
statements of operations, changes in stockholders' equity (deficit), and cash
flows for the years ended December 31, 1995, 1996 and 1997. These financial
statements are the responsibility of InterQual's management. Our responsibility
is to express an opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of InterQual, Inc. as of
December 31, 1996 and 1997, and the results of its operations and its cash flows
for the years ended December 31, 1995, 1996 and 1997, in conformity with
generally accepted accounting principles.
 
    As discussed in Note 2 of the financial statements, in fiscal year 1997,
InterQual, Inc. retroactively changed its method of accounting for certain
revenues.

                         NOTES TO FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1995, 1996 AND 1997
 
(1) OPERATIONS
 
    InterQual, Inc., a Delaware corporation, was formed in 1976. InterQual
develops and markets clinical decision support criteria and related Windows-TM-
based software products that help manage point-of-care demand for healthcare
resources and guide and demonstrate the quality of resource use decisions.
InterQual licenses directly to end users and through an alliance partners'
program. Licensees include physician groups, managed care plans, insurers,
hospitals and public programs located throughout the United States and
internationally. For its licensees, InterQual provides implementation, training,
and consulting services. InterQual also conducts physician and ancillary
healthcare provider credentialing services for managed care.
 
(2) SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    InterQual licenses its Clinical Decision Support Criteria primarily pursuant
to multi-year non-cancellable agreements that provide for payment of equal
annual license fees over their terms. These licenses also provide for support
services and annual update rights bundled into the license fee. Revenues related
to annual criteria licenses are typically received upon commencement of the
term, are deferred and recognized ratably over the annual term. Revenues from
other services are recognized when the services are delivered.
 
    In fiscal 1997, InterQual retroactively changed its method of recognizing
revenue related to criteria licenses rights from recognition at the beginning of
the annual term to recognition ratably over the annual term. The financial
statements for all periods presented have been restated to reflect the
correction of this error. The effect of the restatement was a decrease to
revenue of $2,212,561 and $2,190,329 for the years ended December 31, 1995 and
1996, respectively. The effect of the restatement was a decrease to net income
before income tax expense of $2,212,561 and $2,190,329 for the years ended
December 31, 1995 and 1996, respectively and a decrease to net income of
$1,330,785 and $1,355,777 for the years ended December 31, 1995 and 1996,
respectively. The effect of the restatement was a decrease to basic earnings per
share of $133.08 and $135.58 for the years ended December 31, 1995 and 1996,
respectively and a decrease to diluted earnings per share of $127.61 and $124.04
for the years ended December 31, 1995 and 1996, respectively.
 
CASH AND CASH EQUIVALENTS
 
    InterQual's policy is to consider checking accounts, money market accounts,
overnight bank investments, and short-term commercial paper, as cash
equivalents.
 
INVESTMENT
 
    InterQual's investment at December 31, 1996, consisted of common stock of
MediQual Systems, Inc. (MediQual) representing less than 5% of MediQual's
outstanding stock. This investment was stated at cost which approximates market
value. This investment was sold for carrying value during 1997.

IMPAIRMENT OF LONG-LIVED ASSETS
 
    InterQual reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable from future undiscounted cash flows. Impairment losses are
recorded for the difference between the carrying value and fair value of the
long-lived asset.
 
STOCK-BASED COMPENSATION PLAN
 
    InterQual accounts for its stock-based compensation plans under Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB No. 25"). Effective in 1995, InterQual adopted the disclosure option of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). SFAS 123 requires that companies which do not choose
to account for stock-based compensation as prescribed by the statement, shall
disclose the pro forma effects on earnings as if SFAS 123 had been adopted.
Additionally, certain other disclosures are required with respect to stock
compensation and the assumptions used to determine the pro forma effects of SFAS
123.
 
STOCK SPLIT
 
    On April 17, 1996, InterQual effected a 10 for 1 stock split on all
InterQual Class A Common Stock. On the same date, InterQual effected a 50 for 1
stock split on all InterQual Class B Common Stock. All references in the
accompanying financial statements to the number of common shares have been
retroactively restated to reflect the stock split.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially expose InterQual to concentrations of
credit risk consist primarily of cash and cash equivalents and trade
receivables. InterQual places its temporary cash investments in highly rated
financial institutions. InterQual has not experienced any losses on these
investments to date. InterQual has not experienced significant losses related to
receivables from individual customers or groups of customers in the health care
industry or by geographic area. Due to these factors,

(2) SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
no additional credit risk beyond amounts provided for collection losses is
believed by management to be inherent in InterQual's accounts receivable.
 
INTERIM FINANCIAL STATEMENTS
 
    The accompanying interim financial statements have been prepared by
InterQual, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission (the "Commission"). Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations. The accompanying interim financial
statements should be read in conjunction with the financial statements and notes
thereto for fiscal year ended December 31, 1997.
 
    In the opinion of management, the unaudited interim financial statements
reflect all adjustments, consisting of only normal recurring adjustments,
necessary to present fairly InterQual's financial position at March 31, 1998,
results of operations for the three month ended March 31, 1997 and 1998, and
cash flows for the three months ended March 31, 1997 and 1998. Results for the
period ended March 31, 1998 are not necessarily indicative of the results to be
expected for the entire fiscal year.
 
ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(3) INCOME TAXES
 
    The income tax provisions differ from the amount computed by applying the
Federal statutory income tax rate to income before taxes. A reconciliation of
the statutory Federal income tax rate is as follows:

    Significant components of InterQual's deferred income tax assets and

</TABLE>
 
    Deferred income tax assets primarily result from revenue which is deferred
for financial reporting purposes, and recognized in subsequent periods, but must
be included in the determination of the current year's taxable income.
Accordingly, taxable income is substantially higher than financial reporting
pre-tax income. The deferred tax asset will be realized as the deferred revenue
is recognized for financial purposes. Accordingly, InterQual does not believe
that the realization is subject to substantial uncertainty due to the ability to
recognize such revenues in future periods.
 
(4) NOTE PAYABLE TO A BANK
 
    In June, 1996, InterQual established a line of credit agreement for $750,000
with a bank, renewable annually. In December, 1997, a new line of credit was
established for $2,000,000. Under the agreement, borrowings are due on demand
and bear interest at the bank's prime rate (8.5% and 8.25% as of December 31,
1997 and 1996). The note is secured by substantially all assets and requires
that certain covenants be met. InterQual met all covenants as of December 31,
1997.

(6) NOTES PAYABLE TO OFFICERS/STOCKHOLDERS
 
    Notes payable to certain officers and stockholders accrued interest at prime
rate (8.25% at December 31, 1996).
 
    These notes were subordinated to bank borrowings and, accordingly, were
classified as noncurrent. At December 31, 1996, accrued interest of $74,921 is
included in accrued expenses of which $63,086 and $11,835 are payable to Charles
M. Jacobs and Joanne Lamprey, respectively. These notes were paid in full during
1997.
 
(7) RETIREMENT PLAN
 
    InterQual has a 401(k) plan which provides for tax-deferred employee
benefits in compliance with section 401(k) of the Internal Revenue Code. The
401(k) plan allows eligible employees to make contributions up to a maximum of
15% of their salary, as defined, a portion of which may be matched by InterQual.
In addition, InterQual may make additional contributions at its discretion.
InterQual elected to contribute 50% of the employee contribution up to $500 per
employee for 1995, 1996 and 1997. The

(9) CASH SURRENDER VALUE OF OFFICERS' LIFE INSURANCE
 
    InterQual is the beneficiary of various life insurance policies on key
officers of InterQual. The aggregate face amount of the policies was
approximately $2,800,000 and $2,250,000 at December 31, 1997 and March 31, 1998,
respectively.
 
(10) NON-QUALIFIED STOCK OPTION PLAN
 
    During 1994, InterQual adopted a Nonqualified Stock Option Plan (the "Plan")
whereby options to purchase up to 2,000 shares of InterQual's Class B Common
Stock may be granted to key employees, officers, directors, or independent
contractors. Under the terms of the Plan, InterQual has the right to repurchase
all or a portion of the shares purchased at the option price should the optionee
cease to be affiliated with InterQual.

(10) NON-QUALIFIED STOCK OPTION PLAN (CONTINUED)
    The weighted average fair value of each option grant has been estimated as
of the date of the grant using the Black-Scholes option pricing model and the
following assumptions:
 
<TABLE>

                                                                    1995       1996       1997

<S>                                                               <C>        <C>        <C>
Dividend rate...................................................          0%         0%         0%
Expected volatility.............................................      0.001%     0.001%      72.2%
Risk free interest rate.........................................        6.0%       6.0%       6.8%
Expected life (in years)........................................        3.0        2.0        2.0
</TABLE>
 
    Using these assumptions, the fair value of the stock options granted in
1995, 1996, and 1997 was estimated to be approximately $3,000, $12,700, and
$4,900, respectively, which, under SFAS 123, would be amortized as compensation
expense over the vesting period of the options. Had compensation cost been
recorded consistent with SFAS 123 utilizing the assumptions detailed above,
InterQual's pro forma net income would have been as follows for the years ended
December 31, 1995, 1996, and 1997.

(11) SUBSEQUENT EVENT (UNAUDITED)
 
    On February 13, 1998, InterQual entered into an Agreement and Plan of
Reorganization ("Merger Agreement") with Access Health, Inc. Subject to the
terms and conditions of the Merger Agreement, InterQual will become a wholly
owned subsidiary of Access Health, Inc. The Merger Agreement provides, among
other things, the mode of effecting the merger and the manner and basis of
converting each issued and outstanding share of capital stock of InterQual into
shares of common stock of Access Health, Inc. The merger is expected to be
accounted for as a pooling of interests pursuant to Accounting Principles Board
Opinion No. 16 "Business Combinations".

           AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION
 
    This AGREEMENT AND PLAN OF REORGANIZATION (this "AGREEMENT") is made and
entered into as of February 13, 1998, as amended and restated on June 4, 1998,
by and among Access Health, Inc., a Delaware corporation ("PARENT"), Access
Acquisition Corp. 98A, a Delaware corporation and a wholly-owned subsidiary of
Parent ("MERGER SUB"), and InterQual, Inc., a Delaware corporation (the
"COMPANY").
 
                                    RECITALS
 
    A. The Boards of Directors of each of the Company, Parent and Merger Sub
believe it is in the best interests of each company and their respective
stockholders that Parent acquire the Company through the statutory merger of
Merger Sub with and into the Company (the "MERGER") and, in furtherance thereof,
have approved the Merger.
 
    B.  Pursuant to the Merger, among other things, and subject to the terms and
conditions of this Agreement, all of the issued and outstanding shares of
capital stock of the Company ("COMPANY CAPITAL STOCK") and all outstanding
options, warrants or other rights to acquire or receive shares of Company
Capital Stock shall be converted into the right to receive shares of voting
Common Stock of Parent ("PARENT COMMON STOCK").
 
    C.  A portion of the shares of Parent Common Stock otherwise issuable by
Parent in connection with the Merger shall be placed in escrow by Parent, the
release of which amount shall be contingent upon certain events and conditions,
all as set forth in Article VII hereof.
 
    D. The Company, Parent and Merger Sub desire to make certain representations
and warranties and other agreements in connection with the Merger.
 
    NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby 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 and the
applicable provisions of the Delaware General Corporation Law ("DELAWARE LAW"),
Merger Sub shall be merged with and into the Company, the separate corporate
existence of Merger Sub shall cease, and the Company shall continue as the
surviving corporation and as a wholly-owned subsidiary of Parent. The Company as
the surviving corporation after the Merger is hereinafter sometimes referred to
as the "SURVIVING CORPORATION."
 
    1.2  EFFECTIVE TIME.  Unless this Agreement is earlier terminated pursuant
to Section 8.1, the closing of the Merger (the "CLOSING") will take place as
promptly as practicable, but no later than three (3) business days, following
satisfaction or waiver of the conditions set forth in Article VI, at the offices
of Wilson Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill
Road, Palo Alto, California, unless another place or time is agreed to by Parent
and the Company. The date upon which the Closing actually occurs is herein
referred to as the "CLOSING DATE." On the Closing Date, the parties hereto shall
cause the Merger to be consummated by filing an Agreement of Merger (or like
instrument) with the Secretary of State of the State of Delaware (the
"CERTIFICATE OF MERGER"), in accordance with the relevant provisions of
applicable law (the time of acceptance by the Secretary of State of Delaware of
such filing being referred to herein as the "EFFECTIVE TIME"). The parties
currently intend that the Closing Date will occur on or prior to June 30, 1998.
 
                                      A-1
<PAGE>
    1.3  EFFECT OF THE MERGER.  At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of Delaware Law. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, all the property, rights, privileges, powers and franchises of the Company
and Merger Sub shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and Merger Sub shall become the debts,
liabilities and duties of the Surviving Corporation.
 
    1.4  CERTIFICATE OF INCORPORATION; BYLAWS.
 
    (a) Unless otherwise determined by Parent prior to the Effective Time, at
the Effective Time, the Certificate of Incorporation of Merger Sub shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter

however, that Article I of the Certificate of Incorporation of the Surviving
Corporation shall be amended to read as follows: "The name of the corporation is
InterQual, Inc."
 
    (b) Unless otherwise determined by Parent, 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.  The director(s) of Merger Sub immediately
prior to the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of the
Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.
 
    1.6  MERGER CONSIDERATION; EFFECT ON CAPITAL STOCK.  The maximum number of
shares of Parent Common Stock to be issued in exchange for the acquisition by
Parent of all outstanding Company Capital Stock and all unexpired and
unexercised options, warrants or other rights to acquire Company Capital Stock
shall be the Aggregate Share Number (as defined in Section 1.6(f)(ii)). No
adjustment shall be made in the number of shares of Parent Common Stock issued
in the Merger as a result of any cash proceeds received by the Company from the
date hereof to the Effective Time pursuant to the exercise of options, warrants
or other rights to acquire Company Capital Stock. Subject to the terms and
conditions of this Agreement, as of the Effective Time, by virtue of the Merger
and without any action on the part of Merger Sub, the Company or the holder of
any shares of the Company Capital Stock, the following shall occur:
 
        (a)  CONVERSION OF COMPANY COMMON STOCK.  Each share of Class A Common
Stock and Class B Common Stock of the Company (collectively, the "COMPANY COMMON
STOCK") issued and outstanding immediately prior to the Effective Time (other
than any shares of Company Capital Stock to be canceled pursuant to Section
1.6(b) and any Dissenting Shares (as defined and to the extent provided in
Section 1.7(a)) will be canceled and extinguished and be converted automatically
into the right to receive that number of shares of Parent Common Stock equal:
(1) in the case of Class A Common Stock, the Exchange Ratio (as defined in
Section 1.6(f)(iv) below) or (2) in the case of Class B Common Stock, the
product of .99 and the Exchange Ratio, each upon surrender of the certificate
representing such share of Company Common Stock in the manner provided in
Section 1.8.
 
        (b)  CANCELLATION OF PARENT-OWNED AND COMPANY-OWNED STOCK.  Each share
of Company Capital Stock owned by Merger Sub, Parent, the Company or any direct
or indirect wholly-owned subsidiary of Parent or the Company immediately prior
to the Effective Time shall be canceled and extinguished without any conversion
thereof.
 
        (c)  CAPITAL STOCK OF MERGER SUB.  Each share of Common Stock of Merger
Sub issued and outstanding immediately prior to the Effective Time shall be
converted into and exchanged for one validly issued, fully paid and
non-assessable share of Common Stock 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.
 
                                      A-2
<PAGE>
        (d)  ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio 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
Parent Common Stock or Company Capital Stock), reorganization, recapitalization
or other like change with respect to Parent Common Stock or Company Capital
Stock occurring after the date hereof and prior to the Effective Time.
 
        (e)  FRACTIONAL SHARES.  No fraction of a share of Parent Common Stock
will be issued, but in lieu thereof, each holder of shares of Company Capital
Stock who would otherwise be entitled to a fraction of a share of Parent Common
Stock (after aggregating all fractional shares of Parent Common Stock to be
received by such holder) shall be entitled to receive from Parent an amount of
cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the closing price of a share of Parent Common Stock
on the trading day immediately prior to the Closing Date, as reported on the
Nasdaq National Market.
 
        (f)  DEFINITIONS.
 
            (i)  AGGREGATE COMMON NUMBER.  The "AGGREGATE COMMON NUMBER" shall
mean the sum of the aggregate number of shares of Company Class A Common Stock
and the aggregate number of shares of Company Class B Common Stock multiplied by
0.99 outstanding immediately prior to the Effective Time.
 
            (ii)  AGGREGATE SHARE NUMBER.  The "AGGREGATE SHARE NUMBER" shall be
4,290,000 shares of Parent Common Stock, as appropriately adjusted to reflect
the effect of any stock split, stock dividend, reorganization, recapitalization
or the like with respect to the Parent Common Stock occurring after the date
hereof and prior to the Effective Time (a "RECAPITALIZATION OF THE PARENT COMMON
STOCK"); provided, however, that if the Market Price of Parent Common Stock is
less than $30.3030303 (as appropriately adjusted to reflect a Recapitalization
of the Parent Common Stock), the Aggregate Share Number shall be increased by
the number of shares of Parent Common Stock equal to the lesser of (A) fifty
percent (50%) of the amount obtained from: (1) the quotient of $130,000,000 and
the Market Price of Parent Common Stock, less (2) 4,290,000, and (B) 250,000.
 
            (iii)  ESCROW AMOUNT.  The "ESCROW AMOUNT" shall be the number of
shares of Parent Common Stock obtained by multiplying (x) the Aggregate Share
Number by (y) 0.05.
 
            (iv)  EXCHANGE RATIO.  The "EXCHANGE RATIO" shall mean the quotient
obtained by dividing (x) the Aggregate Share Number by (y) the Aggregate Common
Number.
 
            (v)  MARKET PRICE.  The "MARKET PRICE OF THE PARENT COMMON STOCK"
shall mean the average closing price of a share of Parent Common Stock over the
twenty (20) consecutive trading days ending three trading days prior to the
Closing Date, as reported on the Nasdaq National Market.
 
    1.7  DISSENTING SHARES.
 
    (a) Notwithstanding any provision of this Agreement to the contrary, any
shares of Company Capital Stock held by a holder who has demanded and perfected
appraisal or dissenters' rights for such shares in accordance with Delaware Law
and who, as of the Effective Time, has not effectively withdrawn or lost such
appraisal or dissenters' rights ("DISSENTING SHARES") shall not be converted
into or represent a right to receive Parent Common Stock pursuant to Section
1.6, but the holder thereof shall only be entitled to such rights as are granted
by Delaware Law.
 
    (b) Notwithstanding the provisions of subsection (a), if any holder of
shares of Company Capital Stock who demands appraisal of such shares under
Delaware Law shall effectively withdraw or lose (through failure to perfect or
otherwise) the right to appraisal, then, as of the later of the Effective Time
and the occurrence of such event, such holder's shares shall automatically be
converted into and represent only the right to receive Parent Common Stock and
fractional shares as provided in Section 1.6, without interest thereon, upon
surrender of the certificate representing such shares.
 
                                      A-3
<PAGE>
    (c) The Company shall give Parent (i) prompt notice of any written demands
for appraisal of any shares of Company Capital Stock, withdrawals of such
demands, and any other instruments served pursuant to Delaware Law and received
by the Company and (ii) the opportunity to participate in all negotiations and
proceedings with respect to demands for appraisal under Delaware Law. The
Company shall not, except with the prior written consent of Parent, voluntarily
make any payment with respect to any demands for appraisal of capital stock of
the Company or offer to settle or settle any such demands.
 
    1.8  SURRENDER OF CERTIFICATES.
 
        (a)  EXCHANGE AGENT.  First Chicago Trust Company of New York shall act
as exchange agent (the "EXCHANGE AGENT") in the Merger.
 
        (b)  PARENT TO PROVIDE COMMON STOCK.  Promptly after the Effective Time,
Parent shall make available to the Exchange Agent for exchange in accordance
with this Article I, the aggregate number of shares of Parent Common Stock
issuable pursuant to Section 1.6 in exchange for outstanding shares of Company
Capital Stock; provided that, on behalf of the holders of Company Capital Stock,
Parent shall deposit into an escrow account a number of shares of Parent Common
Stock equal to the Escrow Amount out of the aggregate number of shares of Parent
Common Stock otherwise issuable pursuant to Section 1.6. The portion of the
Escrow Amount contributed on behalf of each holder of Company Capital Stock
shall be in proportion to the aggregate number of shares of Parent Common Stock
which such holder would otherwise be entitled to receive under Section 1.6 by
virtue of ownership of outstanding shares of Company Capital Stock.
 
        (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 Company Capital Stock and which
shares were converted into the right to receive shares of Parent Common Stock
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 delivery of the Certificates to the Exchange Agent and shall be
in such form and have such other provisions as Parent may reasonably specify)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Parent Common Stock. Upon
surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Parent, 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 a certificate representing the number of whole
shares of Parent Common Stock (less the number of shares of Parent Common Stock
to be deposited in the Escrow Fund (as defined in Article VII herein) on such
holder's behalf pursuant to Article VII hereof), plus cash in lieu of fractional
shares in accordance with Section 1.6, to which such holder is entitled pursuant
to Section 1.6, and the Certificate so surrendered shall forthwith be canceled.
As soon as practicable after the Effective Time, and subject to and in
accordance with the provisions of Article VII hereof, Parent shall cause to be
distributed to the Escrow Agent (as defined in Article VII) a certificate or
certificates representing that number of shares of Parent Common Stock equal to
the Escrow Amount, which certificate shall be registered in the name of the
Escrow Agent. Such shares shall be beneficially owned by the holders on whose
behalf such shares were deposited in the Escrow Fund and shall also be available
for sale by such holders subject to the resale restrictions contained in the
Affiliate Agreements described in Section 5.14 herein and applicable federal and
state securities law. The proceeds from the sale of such shares shall remain in
the Escrow Fund. The shares of Parent Common Stock deposited in the Escrow Fund,
and the proceeds from the sale of any shares of Parent Common Stock deposited in
the Escrow Fund shall be available to compensate Parent as provided in Article
VII. Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented shares of Company Capital Stock will be deemed from
and after the Effective Time, for all corporate purposes to evidence the
ownership of the number of full shares of Parent Common Stock into which such
shares of Company Capital 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>
        (d)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions with respect to Parent Common Stock declared or made after
the Effective Time and with a record date after the Effective Time will be paid
to the holder of any unsurrendered Certificate with respect to the shares of
Parent 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 Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore payable with respect to such whole shares of Parent
Common Stock.
 
        (e)  TRANSFERS OF OWNERSHIP.  If any certificate for shares of Parent
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 Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.
 
        (f)  NO LIABILITY.  Notwithstanding anything to the contrary in this
Section 1.8, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to a holder of shares of Parent Common Stock or Company
Capital Stock for any amount properly paid to a public official pursuant to any
applicable abandoned property, escheat or similar law.
 
    1.9  NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof (including any cash paid in
respect thereof) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
shares of Company Capital 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.
 
    1.10  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificates
evidencing shares of Company Capital Stock shall have been lost, stolen or
destroyed, the Exchange Agent shall issue 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 Parent Common Stock and cash for fractional
shares, if any, as may be required pursuant to Section 1.6; provided, however,
that Parent 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 Parent or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.
 
    1.11  TAX AND ACCOUNTING CONSEQUENCES.  It is intended by the parties hereto
that the Merger shall (i) constitute a reorganization within the meaning of
Section 368 of the Internal Revenue Code of 1986, as amended (the "CODE") and
(ii) qualify for accounting treatment as a pooling of interests.
 
    1.12  DISSENTING SHARES AFTER PAYMENT OF FAIR VALUE.  Dissenting shares, if
any, after payments of fair value in respect thereto have been made to
dissenting stockholders of the Company pursuant to Delaware Law, shall be
canceled.
 
    1.13  TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective Time, any such 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
 
                                      A-5
<PAGE>
and franchises of the Company and Merger Sub, the officers and directors of the
Company 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.
 
    1.14  KNOWLEDGE.  Subject to Section 9.2 herein, as used in this Agreement,
the term "knowledge" or "aware" shall include all information that a party had
actual knowledge of or should reasonably be expected to have known.
 
                                   ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company hereby represents and warrants to Parent and Merger Sub, subject
to such exceptions as are specifically disclosed in the disclosure schedule

EFFECT"). The Company has delivered a true and correct copy of its Certificate
of Incorporation and Bylaws, each as amended to date, to Parent.

Option, the domicile address of such holder, the number of shares of Common

Company or obligating the Company to grant, extend, accelerate the vesting of,

this Agreement by the Company's stockholders, the Company has all requisite
corporate power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The vote required of the Company's
stockholders to duly approve the Merger and this Agreement is a majority of the

courts of equity powers). Except as set forth on Schedule 2.4, subject only to
the approval of the Merger and this Agreement by the Company's stockholders, the

       other encumbrances of any sort ("LIENS") on the assets of the Company
       relating to or attributable to Taxes (other than for current taxes not
       yet due and payable).
 
          (viii) The Company has no knowledge of any basis for the assertion of

(non-compete or otherwise), commitment, judgment, injunction, order or decree to
which the Company is a party or otherwise binding upon the Company which has or
reasonably could be expected to have the effect of prohibiting or impairing any

intangible) by the Company or the conduct of business by the Company. Without
limiting the foregoing, except for those restrictions set forth in the contracts
which are disclosed in the Company's schedule, the Company has not entered into
 
                                      A-10

    date of the lease and each amendment thereto and the aggregate annual rental
    and/or other fees payable under any such lease. To the knowledge of the
    Company, all such leases are in full force and effect, are valid and
    effective in accordance with their respective terms, and there is not, on
    the part of the Company under any of such leases, any existing default or
    event of default (or event which with notice or lapse of time, or both,
    would constitute a default).
 
        (b) The Company has good and valid title to, or, in the case of leased
    properties and assets, valid leasehold interests in, all of its tangible
    properties and assets, real, personal and mixed, used or held for use in its
    business, free and clear of any Liens (as defined in Section 2.8(b)(vii)),
    except as reflected in the Unaudited Company Financials or in Schedule
    2.10(b) and except for liens for taxes not yet due and payable and such
    imperfections of title and encumbrances, if any, which are not material in
    character, amount or extent, and which do not materially detract from the
    value, or materially interfere with the present use, of the property subject
    thereto or affected thereby.
 
    2.11  INTELLECTUAL PROPERTY.
 
        (a) The Company owns, possesses or has rights to use all intellectual
    property rights, including, without limitation, licenses or other rights to
    use all computer software, software programs, all source and object code,
    algorithms, architecture, structure, display screens, layouts, development
    tools, trademarks, trademark applications, trade secrets, service mark
    applications, trade names, copyrights, copyright applications, compilations,
    inventions, mask work rights, mask work applications, franchises, drawings,
    designs, customer lists, proprietary know-how or proprietary processes or
    formulae, or other rights with respect thereto, and all documentation and
    media constituting, describing or relating to the above, including, without
    limitation, manuals, memoranda and records (collectively referred to as
    "INTELLECTUAL PROPERTY"), presently used in and material to the business of
    the Company as it is now being conducted as of the date of this Agreement
    including products currently under development (the "COMPANY INTELLECTUAL
    PROPERTY RIGHTS"). The Company Intellectual Property that has been developed
    by the Company is exclusively owned by the Company (except for material
    licensed from third parties to the Company for inclusion and incorporation
    into the Company Intellectual Property) and is free and clear of any liens.
    Schedule 2.11(a) sets forth a complete list of all material patents,
    registered and unregistered trademarks, registered copyrights, trade names
    and service marks, and any applications therefor, included in the Company
    Intellectual Property Rights, and specifies, where applicable, the
    jurisdictions in which each such Company Intellectual Property Right has
    been issued or registered or in which an application for such issuance and
    registration has been filed, including the respective registration or
    application numbers and the names of all registered owners.
 
        (b) Schedule 2.11(b) sets forth a complete list of all material
    licenses, sublicenses and other agreements to which the Company is a party,
    which results in annual revenues to or payments by the Company in excess of
    $100,000 and pursuant to which the Company or to the Company's knowledge any
    other person is authorized to use any Company Intellectual Property Right
    (excluding object code end-user licenses granted to end-users in the
    ordinary course of business that permit use of software products without a
    right to modify, distribute or sublicense the same ("END-USER LICENSES")) or
    any trade secret of the Company, and includes the identity of all parties
    thereto. No person who has licensed Intellectual Property to the Company,
    where such Intellectual Property is a material component of any product
    offered by the Company, has ownership rights or license rights to
    improvements made by the Company in such Intellectual Property which has
    been licensed to the
 
                                      A-11
<PAGE>
    Company. Except as listed in Schedule 2.11(b)(ii), the execution and
    delivery of this Agreement by the Company, and the consummation of the
    transactions contemplated hereby, will neither cause the Company to be in
    violation or default under any material license, sublicense or agreement,
    nor entitle any other party to any such license, sublicense or agreement to
    terminate or modify such license, sublicense or agreement.
 
        (c) (i)  Except as listed in Schedule 2.11(c)(i), no claims with respect
    to the Company Intellectual Property Rights have been asserted since 1985
    or, to the Company's knowledge, are threatened by any person, nor, to the
    Company's knowledge, are there any valid grounds for any bona fide claims
    (A) to the effect that the manufacture, sale, licensing or use of any of the
    products of, or providing of any services by, the Company infringes on any
    copyright, patent, trademark, service mark, trade secret or other
    proprietary right or Intellectual Property of any other party, (B) against
    the use by the Company of any Intellectual Property used in and material to
    the Company's business as currently conducted and, to the Company's
    knowledge, products currently under development, or (C) challenging the
    ownership by the Company, validity or effectiveness of any of the Company
    Intellectual Property Rights. All registered trademarks, service marks and
    copyrights held by the Company are valid and subsisting. The business of the
    Company as currently conducted and, to the Company's knowledge, including
    products currently under development by the Company has not and does not
    infringe on any Intellectual Property of any third party. Except as set
    forth on Schedule 2.11(c)(ii), to the Company's knowledge, there is no
    material unauthorized use, infringement or misappropriation of any of the
    Company Intellectual Property Rights by any third party, including any
    employee or former employee of the Company. No Company Intellectual Property
    Right or product or service of the Company is subject to any outstanding
    decree, order, judgment, or stipulation restricting in any manner the
    licensing thereof by the Company.
 
            (ii) Each employee who is currently employed by the Company and to
       the Company's knowledge, each employee who has been employed by the
       Company since January 1, 1993 and who has played a material role in the
       development of the Company's Intellectual Property (with the exception of
       those employees listed in Schedule 2.11(c)(iii)) has executed a
       proprietary information and confidentiality agreement substantially in
       the Company's standard forms.
 
        (d) All of the Company's products (including products currently under
    development) will record, store, process, calculate and present calendar
    dates falling on and after (and if applicable, spans of time including)
    January 1, 2000, and will calculate any information dependent on or relating
    to such dates in the same manner, and with the same functionality, data
    integrity and performance, as the products record, store, process, calculate
    and present calendar dates on or before December 31, 1999, or calculate any
    information dependent on or relating to such dates (collectively, "YEAR 2000
    COMPLIANT"). All of the Company's material products will lose no
    functionality with respect to the introduction of records containing dates
    falling on or after January 1, 2000. Except as set forth on Schedule
    2.11(d), all of the Company's internal computer systems which are material
    to the Company's operations (excluding any End User Licenses) and
    proprietary software products are Year 2000 Compliant. The Company has
    received an oral assurance from its accounting systems provider that the
    Company's accounting systems and software are Year 2000 Compliant and the
    Company is not aware of any reason why the Company's accounting systems and
    software would not be Year 2000 Compliant.

    3.6  LITIGATION.  There is no action, suit or proceeding of any nature
pending or, to the Parent's knowledge, threatened against the Parent, its

Proxy Statement (as defined below in Section 5.1) shall, at the respective times
such documents are filed with the SEC, and, in the case of the Registration

Intellectual Property presently used in and material to the business of Parent
as it is now being conducted as of the date of this Agreement including products
currently under development ("PARENT INTELLECTUAL PROPERTY RIGHTS"). The
execution and delivery of this Agreement by Parent, and the consummation of the
transactions contemplated hereby, will neither cause Parent to be in violation
or default under any material license, sublicense or other agreement to which
Parent is a party and under which Parent or, to Parent's knowledge, any other
person is authorized to use any Parent Intellectual Property Rights (excluding
any end-user licenses), nor entitle any other party to any such license,
sublicense or agreement to terminate or modify such license, sublicense or
agreement. Except as set forth on Schedule 3.9, no claims with respect to
Parent's Intellectual Property Rights are currently pending or have been
asserted since September 30, 1995 or, to Parent's knowledge, are threatened by
any person, nor are there any valid grounds for any bona fide claims (i) to the
effect that the manufacture, sale, licensing or use of any of the products of,
or providing of any services by, Parent infringes on any copyright, patent,
trademark, service mark, trade secret or other proprietary right or Intellectual
Property of any other party, (ii) against the use by Parent of any Intellectual
Property used in and material to Parent's business as currently conducted
including products currently under development, or (iii) challenging the
ownership by Parent, validity or effectiveness of any of Parent Intellectual
Property Rights. To Parent's knowledge, the business of Parent as currently
conducted including products currently under development by Parent has not and
does not infringe on any Intellectual Property of any third party. To Parent's
knowledge, there is no material unauthorized use, infringement or
misappropriation of any of the Parent Intellectual Property Rights by any third
party, including any employee or former employee of the Parent. No Parent
Intellectual Property Right or product or service of Parent is subject to any
outstanding decree, order, judgment, or stipulation restricting in any manner
the licensing thereof by Parent.

made in any certificate furnished by Parent pursuant to this Agreement, to
Parent's knowledge, contains or will contain at the Effective Time, any untrue

state any material fact necessary in order to make the statements contained
herein or therein, in the light of the circumstances under which made, not
misleading.

(whether accrued, absolute, contingent, matured unmatured or other) which if
known would be required to be reflected in the financial statements of Parent in
accordance with GAAP, except for any such liability, obligation or claim which

    "purchase" in order to cause the Registration Statement to become effective.
    The Joint Proxy Statement shall include the recommendation of the Boards of
    Directors of the Company and Parent in favor of the Merger which shall not
    be changed unless the Board of Directors of the Company or the Parent, as
    the case may be, upon advice of its outside legal counsel, shall determine
    that to include such recommendation or not withdraw such recommendation if
    previously included would constitute a breach of such Board's fiduciary duty
    under applicable law.
 
        (b) The Company shall provide to Parent and its counsel for inclusion in
    the Joint Proxy Statement, in form and substance reasonably satisfactory to
    Parent and its counsel, such information concerning the Company, its

    Company shall use its reasonable best efforts to respond to any comments of
    the SEC and to have the Registration Statement declared effective under the
    Securities Act as promptly as practicable after such filing. The Company
    shall cause the Joint Proxy Statement to be mailed to the Company's
    stockholders and the Parent shall cause the Joint Proxy Statement to be
    mailed to the Parent's stockholders, respectively, at the earliest
    practicable time.
 
        (c) As promptly as practicable after execution of this Agreement, Parent
    and the Company shall prepare and file any other filings required under the

    receipt of comments from any other government agency concerning any Other
    Filings and will supply the other party with copies of all correspondence
    between such party or any of its representatives, on the one hand, and the
    SEC, or its staff, or any other applicable government agency, on the other
    hand, with respect to the Registration Statement or the Joint Proxy
    Statement or Other Filings, as applicable. Whenever any event occurs which
    should be set forth in an amendment or supplement to the Joint Proxy
    Statement and the Registration Statement, or other response in connection
    with an Other Filing, Parent or the Company, as the case may be, shall
    promptly inform the other party of such occurrence and cooperate in filing
    with the SEC or its staff or other government agency.

the ability of Parent to account for the business combination to be effected by
the Merger as a pooling of interests, including the acceleration of vesting of
any options, warrants, restricted stock or other rights to acquire shares of the
capital stock of the Company, which reasonably would be expected to (i)

    another corporation, joint venture or other enterprise or general partner of
    any partnership or a trustee of any trust, whether pertaining to any matter
    arising before or after the Effective Time.
 
        (c) The rights of each Indemnified Person hereunder shall be in addition
    to any other rights such Indemnified Person may have under Delaware Law, the
    Company's Certificate of Incorporation or Bylaws in effect prior to the
    Effective Time, any agreement or otherwise. The provisions of this Section
    5.23 shall survive the consummation of the Merger for a period of six years
    and are expressly intended to benefit and may be relied upon each of the
    Indemnified Persons; provided, however, that in the event that any claim or
    claims for indemnification are asserted or made within such six-year period,
    all rights to indemnification in respect of any such claim or claims shall
    continue until disposition of any and all such claims.

    on the date of this Agreement; provided, however, that to the extent Parent

    conditions existing immediately prior to the Effective Time, Parent may, in
    its sole discretion, substitute a comparable plan or (ii) make available to
    eligible employees of the Company employee benefits under plans of Parent
    that provide benefits that are no less favorable, taken as a whole, to the
    benefits provided to similarly situated employees of Parent.
 
        (b) In the event that Parent permits employees of the Company to
    participate in its employee benefit plans (the "PARENT PLANS"), then for
    purposes of determining the eligibility, vesting of benefits, or entitlement
    to benefits (including any severance or vacation plans or arrangements of
    Parent), the calculation of service credited for employees of the Company
    under Parent Plans shall be based on service credited pursuant to the
    comparable plan maintained by Company immediately prior to the Effective
    Time.
 
        (c) The provisions of this Section 5.24 are intended to benefit, and may
    be enforced by the employees covered by such provisions. This Section 5.24

representations and warranties in this Agreement or in any instrument delivered
pursuant to this Agreement (each as modified by the Disclosure Schedule) and all
of Parent's and Merger Sub's representations and warranties in this Agreement or
in any instrument delivered pursuant to this Agreement shall survive the Merger
and continue until 5:00 p.m., California time, on the date which is six months
following the Effective Time (the "EXPIRATION DATE"), except that Parent's
representations and warranties in Sections 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10,

    7.2  ESCROW ARRANGEMENTS.
 
        (a)  ESCROW FUND.  At the Effective Time, the Company's stockholders
will be deemed to have received and deposited with the Escrow Agent (as defined
below) the Escrow Amount (plus any additional shares as may be issued upon any
Recapitalization of Parent Common Stock effected by Parent after the Effective
Time) without any act of any stockholder. As soon as practicable after the
Effective Time, the Escrow Amount, without any act of any stockholder, will be
deposited with The First National Bank of Chicago, (or other institution
acceptable to Parent and the Securityholder Agent (as defined in Section 7.2(g)
below)) as Escrow Agent (the "ESCROW AGENT"), such deposit to constitute an
escrow fund (the "ESCROW FUND") to be governed by the terms set forth herein and
at Parent's cost and expense. The portion of the Escrow Amount contributed on
behalf of each stockholder of the Company shall be in proportion to the
aggregate Parent Common Stock which such holder would otherwise be entitled
under Section 1.6(a). The Escrow Fund shall be available to compensate Parent
and its affiliates for any claims, losses, liabilities, damages, deficiencies,
costs and expenses, including reasonable attorneys' fees and expenses, and
expenses of investigation and defense (calculated after deduction for insurance
proceeds recovered or recoverable) (hereinafter individually a "LOSS" and
collectively "LOSSES") incurred by Parent or for which Parent would otherwise be
liable (including Losses incurred by the Surviving Corporation) as a result of
any inaccuracy or breach of a representation or warranty of the Company or any
contained in Article II herein or in any instrument delivered pursuant to this
Agreement (each as modified by the Disclosure Schedule), or any failure by the
Company to perform or comply with any covenant contained herein. Parent and the
Company each acknowledge that such Losses, if any, would relate to unresolved
contingencies existing at the Effective Time, which if resolved at the Effective
Time would have led to a reduction in the aggregate Merger consideration. The
right of Parent and its subsidiaries (including the Surviving Corporation) after
the Effective Time to assert indemnification claims and receive indemnification
payments from the Escrow Fund pursuant to this Article VII shall be the sole and
exclusive right and remedy exercisable by such parties with respect to any
breach in any representation, warranty, or covenant contained in this Agreement
or in any certificate delivered pursuant to this Agreement or in connection with
the transactions contemplated hereby. Parent may not receive any shares from the
Escrow Fund unless and until Officer's Certificates (as defined in paragraph (d)
below) identifying Losses, the aggregate amount of which exceed $750,000 (the
"ESCROW BASKET"), have been delivered to the Escrow Agent as provided in
paragraph (e); in such case, Parent may recover from the Escrow Fund the total
of its cumulative Losses, including the first $750,000. For the sole purpose of
calculating Losses to extent arising as a result of an incident to a breach of
representation and warranty of the Company, set forth herein, such
representations and warranties shall

be read as if all references to "material" and "materiality" and phrases of
similar meaning were deleted therefrom. Notwithstanding the foregoing, Parent
may receive shares from the Escrow Fund in connection with reimbursement for any
Excess Expenses upon delivery to the Escrow Agent of a certificate signed by any
officer of Parent, without regard for the Escrow Basket stated above. The
procedures for obtaining such reimbursement shall be similar to the procedures
set forth in Section 7.2(b)-(k) herein for obtaining indemnification for Losses
in that the Parent shall submit a claim upon payment of any Excess Expenses.
 
        (b)  ESCROW PERIOD; DISTRIBUTION UPON TERMINATION OF ESCROW
PERIODS.  Subject to the following requirements, the Escrow Fund shall be in
existence immediately following the Effective Time and shall terminate at 5:00
p.m., California time, on the Expiration Date (the "ESCROW PERIOD"); provided
that the Escrow Period shall not terminate with respect to such amount (or some
portion thereof), that together with the aggregate amount remaining in the
Escrow Fund is necessary in the reasonable judgment of Parent, subject to the
objection of the Securityholder Agent and the subsequent arbitration of the
matter in the manner provided in Section 7.2(f) hereof, to satisfy any
unsatisfied Losses concerning facts and circumstances existing prior to the
termination of such Escrow Period specified in any Officer's Certificate
delivered to the Escrow Agent prior to termination of such Escrow Period. As
soon as all such Losses have been resolved, the Escrow Agent shall deliver to
the stockholders of the Company the remaining portion of the Escrow Fund not
required to satisfy any other such unresolved Loss. Deliveries of Escrow Amounts
to the stockholders of the Company pursuant to this Section 7.2(b) shall be made
in proportion to their respective original contributions to the Escrow Fund.
 
        (c)  PROTECTION OF ESCROW FUND.
 
            (i) The Escrow Agent shall hold and safeguard the Escrow Fund during
       the Escrow Period, shall treat such fund as a trust fund in accordance
       with the terms of this Agreement and not as the property of Parent and
       shall hold and dispose of the Escrow Fund only in accordance with the
       terms hereof.
 
            (ii) Any shares of Parent Common Stock or other equity securities
       issued or distributed by Parent (including shares issued upon a stock
       split) ("NEW SHARES") in respect of Parent Common Stock in the Escrow
       Fund which have not been released from the Escrow Fund shall be added to
       the Escrow Fund and become a part thereof. New Shares issued in respect
       of shares of Parent Common Stock which have been released from the Escrow
       Fund shall not be added to the Escrow Fund but shall be distributed to
       the recordholders thereof. Cash dividends on Parent Common Stock in the
       Escrow Fund will be distributed to the recordholders thereof as a
       condition to receiving payment of such dividends, but in the event that
       Parent Common Stock is delivered from the Escrow Fund to the Parent, the
       recordholders thereof shall agree to return any dividends received on
       such stock to the Escrow Fund for distribution to Parent as a condition
       to receiving payment of such dividends.
 
           (iii) Each stockholder shall have voting rights with respect to the
       shares of Parent Common Stock contributed to the Escrow Fund by such
       stockholder (and on any voting securities added to the Escrow Fund in
       respect of such shares of Parent Common Stock).
 
            (iv) No Stockholder may assign or transfer any rights in Parent
       Common Stock that is held in the Escrow Fund except in connection with a
       sale of Parent Common Stock in accordance with Section 1.8(c).
 
        (d)  CLAIMS UPON ESCROW FUND.
 
            (i) Upon receipt by the Escrow Agent at any time on or before the
       last day of the Escrow Period of a certificate signed by any officer of
       Parent (an "OFFICER'S CERTIFICATE"): (A) stating that Parent has paid or
       properly accrued or reasonably anticipates that it will have to pay or
       accrue Losses, and (B) specifying in reasonable detail the individual
       items of Losses included in the amount so stated, the date each such item
       was paid or properly accrued, or the basis for such
 
                                      A-35
<PAGE>
       anticipated liability, and the nature of the misrepresentation, breach of
       warranty or covenant to which such item is related and to the extent
       known a reasonable summary of the facts underlying the claim, and if no
       objection is received from the Securityholder Agent in accordance with
       Section 7.2(e), the Escrow Agent shall, subject to the provisions of
       Sections 7.2(a) and 7.2(e), deliver to Parent out of the Escrow Fund, as
       promptly as practicable, shares of Parent Common Stock held in the Escrow
       Fund in an amount equal to such Losses.
 
            (ii) For the purposes of determining the number of shares of Parent
       Common Stock to be delivered to Parent out of the Escrow Fund pursuant to
       Section 7.2(d)(i) hereof, the shares of Parent Common Stock shall be
       valued at the market price as reported on the Nasdaq National Market of
       the Parent Common Stock on the trading day prior to the Closing Date.
       Parent and the Securityholder Agent shall certify such fair market value
       in a certificate signed by both Parent and the Securityholder Agent, and
       shall deliver such certificate to the Escrow Agent.
 
        (e)  OBJECTIONS TO CLAIMS.  At the time of delivery of any Officer's
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Securityholder Agent and for a period of thirty (30) days after
such delivery, the Escrow Agent shall make no delivery to Parent of any Escrow
Amounts pursuant to Section 7.2(d) hereof unless the Escrow Agent shall have
received written authorization from the Securityholder Agent to make such
delivery. After the expiration of such thirty (30) day period, the Escrow Agent
shall make delivery of shares of Parent Common Stock from the Escrow Fund in
accordance with Section 7.2(d) hereof, provided that no such payment or delivery
may be made if the Securityholder Agent shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent prior to the expiration of such thirty (30) day
period.
 
        (f)  RESOLUTION OF CONFLICTS; ARBITRATION.
 
            (i) In case the Securityholder Agent shall so object in writing to
       any claim or claims made in any Officer's Certificate, the Securityholder
       Agent and Parent shall attempt in good faith to agree upon the rights of
       the respective parties with respect to each of such claims. If the
       Securityholder Agent and Parent should so agree, a memorandum setting
       forth such agreement shall be prepared and signed by both parties and
       shall be furnished to the Escrow Agent. The Escrow Agent shall be
       entitled to rely on any such memorandum and distribute shares of Parent
       Common Stock from the Escrow Fund in accordance with the terms thereof.
 
            (ii) If no such agreement can be reached after good faith
       negotiation, either Parent or the Securityholder Agent may demand
       arbitration of the matter unless the amount of the damage or loss is at
       issue in pending litigation with a third party, in which event
       arbitration shall not be commenced until such amount is ascertained or
       both parties agree to arbitration; and in either such event the matter
       shall be settled by arbitration conducted by three arbitrators. Parent
       and the Securityholder Agent shall each select one arbitrator, and the
       two arbitrators so selected shall select a third arbitrator. The
       arbitrators shall set a limited time period and establish procedures
       designed to reduce the cost and time for discovery while allowing the
       parties an opportunity, adequate in the sole judgment of the arbitrators,
       to discover relevant information from the opposing parties about the
       subject matter of the dispute. The arbitrators shall rule upon motions to
       compel or limit discovery and shall have the authority to impose
       sanctions, including attorneys' fees and costs, to the extent as a court
       of competent law or equity, should the arbitrators determine that
       discovery was sought without substantial justification or that discovery
       was refused or objected to without substantial justification. The
       decision of a majority of the three arbitrators as to the validity and
       amount of any claim in such Officer's Certificate shall be binding and
       conclusive upon the parties to this Agreement, and notwithstanding
       anything in Section 7.2(e) hereof, the Escrow Agent shall be entitled to
       act in accordance with such decision and make or withhold payments out of
       the Escrow Fund in accordance therewith. Such decision shall
 
                                      A-36
<PAGE>
       be written and shall be supported by written findings of fact and
       conclusions which shall set forth the award, judgment, decree or order
       awarded by the arbitrators.
 
           (iii) Judgment upon any award rendered by the arbitrators may be
       entered in any court having jurisdiction. Any such arbitration shall be
       held in Palo Alto, California under the rules then in effect of the
       American Arbitration Association. For purposes of this Section 7.2(f), in
       any arbitration hereunder in which any claim or the amount thereof stated
       in the Officer's Certificate is at issue, Parent shall be deemed to be
       the Non-Prevailing Party in the event that the arbitrators award Parent
       less than the sum of sixty percent (60%) of the disputed amount plus any
       amounts not in dispute; otherwise, the stockholders of the Company as
       represented by the Securityholder Agent shall be deemed to be the
       Non-Prevailing Party. The Non-Prevailing Party to an arbitration shall
       pay its own expenses, the fees of each arbitrator, the administrative
       costs of the arbitration and the expenses, including without limitation,
       reasonable attorneys' fees and costs ("ESCROW CONTEST FEES"), incurred by
       the other party to the arbitration. If the Parent is the prevailing
       party, the amounts owed by the Non-Prevailing Party shall be paid solely
       from the Escrow Fund, unless the arbitrator determines that the
       Non-Prevailing Party has made an opposition to a claim in bad faith, in
       which case the arbitrator may direct the Non-Prevailing Party to pay some
       or all of the Prevailing Party's Escrow Contest Fees from its own funds
       and not from the Escrow Fund.
 
        (g)  SECURITYHOLDER AGENT OF THE STOCKHOLDERS; POWER OF ATTORNEY.
 
            (i) In the event that the Merger is approved, effective upon such
       vote, and without further act of any stockholder, Charles Jacobs shall be
       appointed as agent and attorney-in-fact (the "SECURITYHOLDER AGENT") for
       each stockholder of the Company (except such stockholders, if any, as
       shall have perfected their appraisal or dissenters' rights under Delaware
       Law), for and on behalf of stockholders of the Company, to give and
       receive notices and communications, to authorize delivery to Parent of
       shares of Parent Common Stock from the Escrow Fund in satisfaction of
       claims by Parent, to object to such deliveries, to agree to, negotiate,
       enter into settlements and compromises of, and demand arbitration and
       comply with orders of courts and awards of arbitrators with respect to
       such claims, and to take all actions necessary or appropriate in the
       judgment of Securityholder Agent for the accomplishment of the foregoing.
       Such agency may be changed by the stockholders of the Company from time
       to time upon not less than thirty (30) days prior written notice to
       Parent; provided that the Securityholder Agent may not be removed unless
       holders of a two-thirds interest of the Escrow Fund agree to such removal
       and to the identity of the substituted agent. Any vacancy in the position
       of Securityholder Agent may be filled by approval of the holders of a
       majority in interest of the Escrow Fund. No bond shall be required of the
       Securityholder Agent, and the Securityholder Agent shall not receive
       compensation for his or her services. Notices or communications to or
       from the Securityholder Agent shall constitute notice to or from each of
       the stockholders of the Company.
 
            (ii) The Securityholder Agent shall not be liable for any act done
       or omitted hereunder as Securityholder Agent while acting in good faith
       and in the exercise of reasonable judgment. The stockholders of the
       Company on whose behalf the Escrow Amount was contributed to the Escrow
       Fund shall severally indemnify the Securityholder Agent and hold the
       Securityholder Agent harmless against any loss, liability or expense
       incurred without negligence or bad faith on the part of the
       Securityholder Agent and arising out of or in connection with the
       acceptance or administration of the Securityholder Agent's duties
       hereunder, including the reasonable fees and expenses of any legal
       counsel retained by the Securityholder Agent.
 
        (h)  ACTIONS OF THE SECURITYHOLDER AGENT.  A decision, act, consent or
instruction of the Securityholder Agent shall constitute a decision of all the
stockholders for whom a portion of the Escrow Amount otherwise issuable to them
are deposited in the Escrow Fund and shall be final, binding and conclusive upon
each of such stockholders, and the Escrow Agent and Parent may rely upon any
such
 
                                      A-37
<PAGE>
decision, act, consent or instruction of the Securityholder Agent as being the
decision, act, consent or instruction of each every such stockholder of the
Company. The Escrow Agent and Parent are hereby relieved from any liability to
any person for any acts done by them in accordance with such decision, act,
consent or instruction of the Securityholder Agent.
 
        (i)  THIRD-PARTY CLAIMS.  In the event Parent becomes aware of a
third-party claim which Parent believes may result in a demand against the
Escrow Fund, Parent shall notify the Securityholder Agent of such claim, and the
Securityholder Agent, as representative for the stockholders of the Company,
shall be entitled, at their expense, to participate in any defense of such
claim. Parent shall have the right in its sole discretion to settle any such
claim; provided, however, that except with the consent of the Securityholder
Agent, no settlement of any such claim with third-party claimants shall alone be
determinative of the amount of any claim against the Escrow Fund. In the event
that the Securityholder Agent has consented in writing to any such settlement
and acknowledged that the claim by Parent is a valid claim against the Escrow
Fund, the Securityholder Agent shall have no power or authority to object under
any provision of this Article VII to the amount of any claim by Parent against
the Escrow Fund with respect to such settlement.
 
        (j)  ESCROW AGENT'S DUTIES.
 
            (i) The Escrow Agent shall be obligated only for the performance of
       such duties as are specifically set forth herein, and as set forth in any
       additional written escrow instructions which the Escrow Agent may receive
       after the date of this Agreement which are signed by an officer of Parent
       and the Securityholder Agent, and may rely and shall be protected in
       relying or refraining from acting on any instrument reasonably believed
       to be genuine and to have been signed or presented by the proper party or
       parties. The Escrow Agent shall not be liable for any act done or omitted
       hereunder as Escrow Agent while acting in good faith and in the exercise
       of reasonable judgment, and any act done or omitted pursuant to the
       advice of counsel shall be conclusive evidence of such good faith.
 
            (ii) The Escrow Agent is hereby expressly authorized to comply with
       and obey orders, judgments or decrees of any court of law,
       notwithstanding any notices, warnings or other communications from any
       party or any other person to the contrary. In case the Escrow Agent obeys
       or complies with any such order, judgment or decree of any court, the
       Escrow Agent shall not be liable to any of the parties hereto or to any
       other person by reason of such compliance, notwithstanding any such
       order, judgment or decree being subsequently reversed, modified,
       annulled, set aside, vacated or found to have been entered without
       jurisdiction.
 
           (iii) The Escrow Agent shall not be liable in any respect on account
       of the identity, authority or rights of the parties executing or
       delivering or purporting to execute or deliver this Agreement or any
       documents or papers deposited or called for hereunder.
 
            (iv) The Escrow Agent shall not be liable for the expiration of any
       rights under any statute of limitations with respect to this Agreement or
       any documents deposited with the Escrow Agent.
 
            (v) In performing any duties under the Agreement, the Escrow Agent
       shall not be liable to any party for damages, losses, or expenses, except
       for gross negligence or willful misconduct on the part of the Escrow
       Agent. The Escrow Agent shall not incur any such liability for (A) any
       act or failure to act made or omitted in good faith, or (B) any action
       taken or omitted in reliance upon any instrument, including any written
       statement or affidavit provided for in this Agreement that the Escrow
       Agent shall in good faith believe to be genuine, nor will the Escrow
       Agent be liable or responsible for forgeries, fraud, impersonations, or
       determining the scope of any representative authority. In addition, the
       Escrow Agent may consult with the legal counsel in connection with Escrow
       Agent's duties under this Agreement and shall be fully protected in any
       act taken, suffered, or permitted by him/her in good faith in accordance
       with the advice of counsel. The Escrow Agent is not responsible for
       determining and verifying the authority of any person acting or
       purporting to act on behalf of any party to this Agreement.
 
                                      A-38
<PAGE>
            (vi) If any controversy arises between the parties to this
       Agreement, or with any other party, concerning the subject matter of this
       Agreement, its terms or conditions, the Escrow Agent will not be required
       to determine the controversy or to take any action regarding it. The
       Escrow Agent may hold all documents and shares of Parent Common Stock and
       may wait for settlement of any such controversy by final appropriate
       legal proceedings or other means as, in the Escrow Agent's discretion,
       the Escrow Agent may be required, despite what may be set forth elsewhere
       in this Agreement. In such event, the Escrow Agent will not be liable for
       damage. Furthermore, the Escrow Agent may at its option, file an action
       of interpleader requiring the parties to answer and litigate any claims
       and rights among themselves. The Escrow Agent is authorized to deposit
       with the clerk of the court all documents and shares of Parent Common
       Stock held in escrow, except all cost, expenses, charges and reasonable
       attorney fees incurred by the Escrow Agent due to the interpleader action
       and which the parties jointly and severally agree to pay. Upon initiating
       such action, the Escrow Agent shall be fully released and discharged of
       and from all obligations and liability imposed by the terms of this
       Agreement.
 
           (vii) The parties and their respective successors and assigns agree
       jointly and severally to indemnify and hold Escrow Agent harmless against
       any and all losses, claims, damages, liabilities, and expenses, including
       reasonable costs of investigation, counsel fees, and disbursements that
       may be imposed on Escrow Agent or incurred by Escrow Agent in connection
       with the performance of his/her duties under this Agreement, including
       but not limited to any litigation arising from this Agreement or
       involving its subject matter.
 
          (viii) The Escrow Agent may resign at any time upon giving at least
       thirty (30) days written notice to the parties; provided, however, that
       no such resignation shall become effective until the appointment of a
       successor escrow agent which shall be accomplished as follows: the
       parties shall use their best efforts to mutually agree on a successor
       escrow agent within thirty (30) days after receiving such notice. If the
       parties fail to agree upon a successor escrow agent within such time, the
       Escrow Agent shall have the right to appoint a successor escrow agent
       authorized to do business in the State of California. The successor
       escrow agent shall execute and deliver an instrument accepting such
       appointment and it shall, without further acts, be vested with all the
       estates, properties, rights, powers, and duties of the predecessor escrow
       agent as if originally named as escrow agent. The Escrow Agent shall be
       discharged from any further duties and liability under this Agreement.
 
        (k)  FEES.  All fees of the Escrow Agent for performance of its duties
hereunder shall be paid by Parent. It is understood that the fees and usual
charges agreed upon for services of the Escrow Agent shall be considered
compensation for ordinary services as contemplated by this Agreement. In the
event that the conditions of this Agreement are not promptly fulfilled, or if
the Escrow Agent renders any service not provided for in this Agreement, or if
the parties request a substantial modification of its terms, or if any
controversy arises, or if the Escrow Agent is made a party to, or intervenes in,
any litigation pertaining to this escrow or its subject matter, the Escrow Agent
shall be reasonably compensated for such extraordinary services and reimbursed
for all costs, attorney's fees, and expenses occasioned by such default, delay,
controversy or litigation. Parent promises to pay these sums upon demand.
 
                                  ARTICLE VIII
                       TERMINATION, AMENDMENT AND WAIVER
 
    8.1  TERMINATION.  Except as provided in Section 8.2 below, this Agreement
may be terminated and the Merger abandoned at any time prior to the Effective
Time:
 
        (a) by mutual consent of the Company and Parent;
 
                                      A-39
<PAGE>
        (b) by Parent or the Company if: (i) the Effective Time has not occurred
    before 5:00 p.m. (Pacific time) on July 3, 1998 (provided that the right to
    terminate this Agreement under this clause 8.1(b)(i) shall not be available
    to any party whose willful failure to fulfill any obligation hereunder has
    been the cause of, or resulted in, the failure of the Effective Time to
    occur on or before such date); (ii) there shall be a final non-appealable
    order of a federal or state court in effect preventing consummation of the
    Merger; (iii) there shall be any statute, rule, regulation or order enacted,
    promulgated or issued or deemed applicable to the Merger by any governmental
    entity that would make consummation of the Merger illegal; or (iv) the
    approval of the Merger by the Company's stockholders required by Section
    5.2(a) or the approval by Parent's stockholders of the issuance of the
    Parent Common Stock pursuant to this Agreement required by Section 5.2(b)
    shall not have been obtained at a meeting duly convened therefor or at any
    adjournment thereof;
 
        (c) by Parent or the Company if there shall be any action taken, or any
    statute, rule, regulation or order enacted, promulgated or issued or deemed
    applicable to the Merger, by any Governmental Entity, which would: (i)
    prohibit Parent's or the Company's ownership or operation of all or any
    portion of the business of the Company or (ii) compel Parent or the Company
    to dispose of or hold separate all or a portion of the business or assets of
    the Company or Parent as a result of the Merger; in either case, the
    unavailability of which assets or business would have a Material Adverse
    Effect on Parent or would reasonably be expected to have a Material Adverse
    Effect on Parent's ability to realize the benefits expected from the Merger;
 
        (d) by Parent if it is not in material breach of its obligations under
    this Agreement and there has been a breach of any representation, warranty,
    covenant or agreement contained in this Agreement on the part of the Company
    and as a result of such breach the conditions set forth in Section 6.3(a) or
    6.3(b), as the case may be, would not then be satisfied; provided, however,
    that if such breach is curable by the Company within (30) days through the
    exercise of its reasonable best efforts, then for so long as the Company
    continues to exercise such reasonable best efforts Parent may not terminate
    this Agreement under this Section 8.1(d) unless such breach is not cured
    within thirty (30) days (but no cure period shall be required for a breach
    which by its nature cannot be cured);
 
        (e) by the Company if it is not in material breach of its obligations
    under this Agreement and there has been a breach of any representation,
    warranty, covenant or agreement contained in this Agreement on the part of
    Parent or Merger Sub and as a result of such breach the conditions set forth
    in Section 6.2(a) or 6.2(b), as the case may be, would not then be
    satisfied; provided, however, that if such breach is curable by Parent or
    Merger Sub within thirty (30) days through the exercise of its reasonable
    best efforts, then for so long as Parent or Merger Sub continues to exercise
    such reasonable best efforts the Company may not terminate this Agreement
    under this Section 8.1(e) unless such breach is not cured within (30) days
    (but no cure period shall be required for a breach which by nature cannot be
    cured);
 
        (f) by the Parent if an event having a Material Adverse Effect on the
    Company shall have occurred after the date of this Agreement;
 
        (g) by the Company if an event having a Material Adverse Effect on the
    Parent shall have occurred after the date of this Agreement; or
 
        (h) by Parent if the Company's Board of Directors shall have failed to
    recommend or change its recommendation concerning the Merger or shall have
    disclosed in any manner its intention to change such recommendation.
 
        (i) by the Company if the Parent's Board of Directors shall have failed
    to recommend or change it recommendation concerning the Merger or shall have
    disclosed in any manner its intention to change such recommendations.
 
                                      A-40

        (j) by the Company for such time but only during such time that the
    average closing price of a share of Parent Common Stock over any twenty (20)
    consecutive trading days as reported on the Nasdaq National Market is less
    than $27.14 per share, as appropriately adjusted to reflect a
    Recapitalization of the Parent Common Stock.
 
    Where action is taken to terminate this Agreement pursuant to this Section
8.1, it shall be sufficient for such action to be authorized by the Board of
Directors (as applicable) of the party taking such action.

    is not in material breach of its obligations under this Agreement, and any
    of the following events has occurred:
 
            (i) the Company has willfully breached any representation, warranty,

       breach the conditions set forth in Section 6.3(a) or 6.3(b), as the case
       may be, would not be satisfied;
 
            (ii) the Merger has been submitted to a vote of the Company's
       stockholders as required hereunder, and the stockholders of the Company
       shall have failed to approve the Merger by a requisite vote required for
       such approval; or
 
           (iii) the Board of Directors of the Company shall have failed to
       recommend or changed its recommendation concerning the Merger, or shall
       have disclosed, in any manner, its intention not to recommend or to

        (b) The Parent shall pay to the Company, a termination fee of
    $3,900,000, payable in cash by wire transfer or cashier's check in the
    event, and only in the event, that the Closing does not occur, this

            (i) Parent has willfully breached any representation, warranty,

       have disclosed, in any manner, its intention not to recommend or to

           (iii) the issuance of the Parent Common Stock pursuant to this

        (c) Any termination payment required under Section 8.3(a) or (b) shall
    be made by the applicable party within ten (10) days after termination of
    this Agreement.
 
        (d) A party's right to a termination fee pursuant to Section 8.3 hereof
    shall be such party's sole and exclusive remedy, provided such party is both
    entitled to and elects to terminate its obligations to
 
                                      A-41
<PAGE>
    consummate the Merger pursuant to Section 8.1 on a date prior to the
    Effective Time (the "TERMINATION DATE"); provided further, if a party is not
    entitled to a termination fee pursuant to Section 8.3 but is otherwise
    entitled to terminate pursuant to Section 8.1, such party shall not have any
    rights or remedies in law or equity against the other party. Notwithstanding
    the foregoing, if as of the Termination Date (i) Parent is entitled to
    receive payment of a termination fee pursuant to Section 8.3(a), (ii) the
    Company is not entitled to exercise the right to terminate its obligations
    under the Agreement pursuant to Section 8.1(j), and (iii) the Company signs
    an agreement or otherwise agrees with a third party (including, but not
    limited to a letter of intent or memorandum of understanding, or term sheet,
    whether or not such agreement, memorandum or term sheet is binding) within
    six (6) months of the Termination Date to effect the merger, consolidation,
    sale of substantially all of the assets of the Company, or transfer or more
    than 50% of the voting securities of the Company in one or more
    transactions, to such third party or any affiliate thereof, then the payment
    called for by this Section 8.3 shall not be deemed to be a liquidated
    damage, and shall be in addition to any rights or remedies that Parent may
    otherwise have at law or equity.
 
    8.4  AMENDMENT.  Except as is otherwise required by applicable law after the
stockholders of the Company approve this Agreement, this Agreement may be
amended by the parties hereto at any time by execution of an instrument in
writing signed on behalf of each of the parties hereto.
 
    8.5  EXTENSION; WAIVER.  At any time prior to the Effective Time, Parent and
Merger Sub, on the one hand, and the Company, on the other, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations of the other party hereto, (ii) waive any inaccuracies in the
representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the
agreements or conditions for the benefit of such party contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party.
 
    8.6  INTENT TO TERMINATE.  At any time when the Company is eligible to
exercise its termination right pursuant to Section 8.1(j), Parent may provide
the Company with a written request (the "TERMINATION INQUIRY") inquiring as to
the Company's intention to terminate the Merger. Upon receipt of such request,
the Company shall have three (3) business days to provide Parent with notice
regarding its intention to exercise its termination rights pursuant to Section
8.1(j). If the Company declines by written notice to terminate the Merger, or if
the Company fails to respond in writing to the Termination Inquiry within three
(3) business days after receipt of the Termination Inquiry, the Company
subsequently may exercise its termination right under Section 8.1(j) if and only
if the conditions of Section 8.1(j) occur during any twenty (20) consecutive
trading days after the date (the "RESPONSE DATE") which is the earlier of the
date the Company has responded in writing to the Termination Inquiry or three
(3) days after the date of the Termination Inquiry. However, if the Closing Date
will occur less than twenty (20) consecutive trading days after the Response
Date, the Company may exercise its termination right under Section 8.1(j)
beginning on the day prior to the Closing Date (the "PRE-CLOSING DATE") if the
conditions of Section 8.1(j) have been met during the twenty (20) consecutive
trading days immediately prior to Pre-Closing Date.

used herein shall be deemed in each case to be followed by the words "without
limitation." The table of contents and headings contained in this Agreement are

    representative of the SEC shall have rendered written advice to Holder
    (sought by Holder or counsel to Holder, with a copy thereof and all other
    related communications delivered to the Company) to the effect that the SEC
    would take no action, or that the staff of the SEC would not recommend that
    the SEC take any action, with respect to the proposed disposition if
    consummated; or (v) when the Holder of Registrable Securities is no longer
    subject to the restrictions in Rule 145 under Rule 145(d)(2) or (3).
    Notwithstanding the foregoing, the Company shall not be obligated to remove
    stop transfer instructions and the legend provided in Section 1.2(a) above
    until such time as a proposed sale, transfer, exchange, pledge, encumbrance
    or
 
                                     A-A-2
<PAGE>
    other disposition of Registrable Securities by a Holder is permitted
    pursuant to Section 1 of the Affiliate/Voting Agreement or Affiliate
    Agreement, as applicable, entered into between such Holder and the Company
    dated February 13, 1998.
 
        (c) Each Holder consents to the Company making a notation on its records
    and giving instructions to any transfer agent of the Registrable Securities
    in order to implement the restrictions on transfer established in this
    Agreement.
 
    1.3  REQUESTED REGISTRATION.
 
        (a) At any time after the Expiration Date, in case the Company shall
    receive a written request from a Holder or Holders that the Company effect
    any registration with respect to Registrable Securities if the anticipated
    aggregate offering price, net of underwriting discounts and commissions,
    would exceed $25,000,000, the Company shall:
 
            (i) promptly give written notice of the proposed registration to all
       other Holders; and
 
            (ii) as soon as practicable, use its best efforts to register
       (including, without limitation, the execution of an undertaking to file
       post-effective amendments, appropriate qualifications under applicable
       blue sky or other state Securities Laws, and appropriate compliance with
       federal government requirements), but in no event later than 45 days from
       receipt of written notice under subsection 1.3(a) hereof, the sale and
       distribution of the Registrable Securities as specified in such request,
       together with all or such portion of the (A) Registrable Securities of
       any other Holder or Holders as are specified in a written request given
       within ten (10) days after receipt of such written notice from the
       Company and (B) securities of all other holders of the Company's
       securities as are specified in a written request given by such holders
       pursuant to registration rights granted by the Company to such holders;
       provided that the Company shall not be obligated to file a registration
       statement pursuant to this Section:
 
               (A) within one hundred twenty (120) days after the effectiveness
           of any registration statement relating to a registration effected
           pursuant to this Section 1.3 or Section 1.4(a);
 
               (B) in any particular state in which the Company would be
           required to execute a general consent to service of process in
           effecting such registration;
 
               (C) in any registration having an aggregate sales price (before
           deduction of underwriting discounts and commissions) of less than
           $25,000,000; or
 
               (D) after the Company has effected two (2) such registrations
           pursuant to this Section 1.3(a) and such registrations have been
           declared or ordered effective; provided, however, that any
           registration request which is subsequently withdrawn shall not be
           deemed to be a registration under this subsection (D) if the Holders
           requesting such registration shall have reimbursed the Company for
           all Registration Expenses related to such withdrawn registration.
 
    Subject to the foregoing clauses (A) through (D), the Company shall file a
registration statement covering the Registrable Securities so requested to be
registered as soon as is practicable after receipt of the request or requests of
the Holders. Notwithstanding the foregoing, if at the time of such request the
Company determines it desires to register shares for the account of the Company,
then the Company can so notify the Holders who shall then have rights to
participate in such registration statement as provided in Section 1.4.
 
        (b) In connection with the registration of Registrable Securities
    pursuant to Section 1.3 hereof, the Company shall select and engage an
    underwriter or underwriters reasonably acceptable to the participating
    Holders, and the Holders agree to distribute the Registrable Securities
    covered by their request by means of an underwriting, using such underwriter
    or underwriters; provided, the Holders shall be entitled to select one
    underwriter, reasonably acceptable to the Company, to serve as a co-
 
                                     A-A-3
<PAGE>
    managing underwriter. The right of any Holder to registration pursuant to
    Section 1.3 shall be conditioned upon such Holder's participation in such
    underwriting and the inclusion of such Holder's Registrable Securities in
    the underwriting to the extent provided herein. The Company shall (together
    with all Holders distributing their Registrable Securities through such
    underwriting) enter into an underwriting agreement in customary form with
    the underwriter or underwriters selected for such underwriting.
    Notwithstanding any other provision of this Section 1.3, if the managing
    underwriter advises the participating Holders in writing that marketing
    factors so as to not materially adversely impact the market price of the
    Company's Common Stock require a limitation of the number of shares to be
    underwritten (an "Underwriter's Cutback"), the Company shall so advise all
    participating Holders, and the managing underwriter may limit the number of
    shares of Registrable Securities that may be included in the registration
    and underwriting to no less than fifty percent (50%) of the total number of
    Registrable Securities requested for inclusion in the registration (the
    "Underwriter's Cutback Limitation"); provided, the Underwriter's Cutback
    Limitation shall only apply until such time as the Holders have collectively
    sold in the aggregate two million (2,000,000) shares of Registrable
    Securities pursuant Sections 1.3, 1.4 or 1.5 hereunder or otherwise pursuant
    to Rule 145 or Rule 144 under the Securities Act (the "Underwriter's Cutback
    Threshold"). Upon such time as Holders have collectively sold in the
    aggregate such number of shares of Registrable Securities equal to the
    Underwriter's Cutback Threshold and the managing underwriter advises the
    Holders of the need for an Underwriter's Cutback, the Company shall so
    advise all participating Holders, and the number of Registrable Securities
    and other securities of the Company that may be included in the registration
    and underwriting shall be allocated among all participating Holders and
    other holders of the Company's securities thereof in proportion, as nearly
    as practicable, to the respective amounts of Registrable Securities and
    other securities of the Company held by such Holders and other holders of
    the Company's securities which have been requested to included in such
    registration and underwriting. If any Holder disapproves of the terms of the
    underwriting, he may elect to withdraw therefrom by written notice to the
    Company and the managing underwriter. If, by the withdrawal of such
    Registrable Securities a greater number of Registrable Securities held by
    other Holders may be included in such registration (up to the limit imposed
    by the underwriters) the Company shall offer to all Holders who have
    included Registrable Securities in the registration the right to include
    additional Registrable Securities in the same proportion used in determining
    the limitation as set forth above. Any Registrable Securities which are
    excluded from the underwriting by reason of the underwriter's marketing
    limitation or withdrawn from such underwriting shall be withdrawn from such
    registration and shall remain subject to the lockup agreement in Section
    1.11.
 
        (c) Notwithstanding anything to the contrary in Section 1.3, if the
    Company shall furnish to such Holders a certificate signed by the President
    of the Company stating that in the good faith judgment of the Board of
    Directors it would be detrimental to the Company and its stockholders for
    such registration statement to be filed within such period (a "Deferral
    Right"), then the Company may defer the filing of a registration statement
    filed pursuant to Section 1.3 hereof for a period of not more than sixty
    (60) days; provided that (A) the Company may not exercise such Deferral
    Right more than once during any one hundred and twenty (120) day period, and
    (B) until the elapse of the Restricted Period, the Company may only exercise
    the Deferral Right based upon (x) the good faith judgment of the Board of
    Directors pursuant to their fiduciary obligations as a result of an action
    initiated by a party other than the Company (and not including an
    acquisition, merger or other business combination pursuant to which the
    Company will acquire or otherwise be the surviving entity in a combination
    or reorganization with another company (not including companies which are
    controlled by the Company as of the date of this Agreement) or negotiations
    or discussions with respect thereto), or (y) the advice of counsel that the
    exercise of such Deferral Right is necessary in order to enable the Company
    to amend the registration statement to comply with the existing rules and
    regulations promulgated under the Securities Act. In the event that during
    the Restricted Period the exercise of the Deferral Right is necessary to
    amend the registration statement to comply with existing rules and
    regulations under the Securities Act, the Company shall use reasonable
    efforts
 
                                     A-A-4
<PAGE>
    to promptly make such amendment; provided, that during such Restricted
    Period the Company shall file such necessary amendment to the registration
    statement no later than fifteen (15) days from the date the Holders are
    provided notice of the need to exercise such Deferral Right. In the event
    the Holders elect to be included in an underwritten public offering pursuant
    to a Registration Opportunity but are unable due to market conditions to
    sell in the aggregate that number of shares of Registrable Securities equal
    to the Underwriter's Cutback Threshold (including in the calculation of such
    Threshold all prior sales of Registrable Securities by all Holders), the
    limitations provided in subsection 1.3(c)(B) shall continue to apply to the
    Company's Deferral Right.
 
    1.4  PIGGYBACK REGISTRATION.
 
        (a) If at any time or from time to time, the Company shall determine to
    register any of its securities, for its own account or the account of any of
    its stockholders, other than a registration relating solely to employee
    benefit plans, a registration statement related to the offering of
    convertible debt securities of the Company, a registration relating solely
    to a Securities Act Rule 145 transaction, or a registration on any form
    (other than Form S-1, S-2 or S-3, or their successor forms) which does not
    include substantially the same information as would be required to be
    included in a registration statement covering the sale of Registrable
    Securities, the Company will:
 
            (i) give to each Holder written notice thereof as soon as
       practicable prior to filing the registration statement; and
 
            (ii) include in such registration and in any underwriting involved
       therein, all the Registrable Securities specified in a written request or
       requests, made within ten (10) days after receipt of such written notice
       from the Company, by any Holder or Holders, except as set forth in
       Subsection (b) below.
 
        (b) If the registration is for a registered public offering involving an
    underwriting, the Company shall so advise the Holders as a part of the
    written notice given pursuant to Subsection 1.4(a)(i). In such event the
    right of any Holder to registration pursuant to Section 1.4 shall be
    conditioned upon such Holder's participation in such underwriting and the
    inclusion of such Holder's Registrable Securities in the underwriting to the
    extent provided herein. All Holders proposing to distribute their securities
    through such underwriting shall (together with the Company) enter into an
    underwriting agreement in customary form with the underwriter or
    underwriters selected for such underwriting by the Company. Notwithstanding
    any other provision of this Section 1.4, if the managing underwriter
    determines that an Underwriter's Cutback is necessary, the managing
    underwriter may limit the number of Registrable Securities to be included in
    the registration and underwriting on behalf of the Holders. In such event,
    the Company shall so advise all participating Holders, and the managing
    underwriter may limit the number of shares of Registrable Securities that
    may be included in the registration and underwriting to no less than the
    Underwriter's Cutback Limitation; provided, the Underwriter's Cutback
    Limitation shall only apply until such time as the Holders have collectively
    sold in the aggregate that number of shares of Registrable Securities equal
    to the Underwriter's Cutback Threshold. Upon such time as Holders have
    collectively sold in the aggregate such number of shares of Registrable
    Securities equal to the Underwriter's Cutback Threshold and the managing
    underwriter advises the Holders of the need for an Underwriter's Cutback,
    the Company shall so advise all participating Holders, and the number of
    Registrable Securities and other securities of the Company (which are either
    proposed to be sold for its own account or the account of a third party),
    that may be included in the registration and underwriting shall be allocated
    among all participating Holders, other holders of the Company's securities
    and the Company thereof in proportion, as nearly as practicable, to the
    respective amounts of Registrable Securities and securities of the Company
    which have been requested to be included (or, in the Company's case, are
    proposed to be included) in such registration and underwriting under this
    Section 1.4. If any Holder disapproves of the terms of any such
    underwriting, he may elect to withdraw therefrom by written notice to the
    Company and the managing underwriter. If, by the withdrawal of such
    Registrable Securities a greater number of Registrable
 
                                     A-A-5
<PAGE>
    Securities held by other Holders may be included in such registration (up to
    the limit imposed by the underwriters) the Company shall offer to all
    Holders who have included Registrable Securities in the registration the
    right to include additional Registrable Securities in the same proportion
    used in determining the limitation as set forth above. Any Registrable
    Securities excluded or withdrawn from such underwriting shall be withdrawn
    from such registration and shall remain subject to the lockup agreement in
    Section 1.11.
 
    1.5  SHELF REGISTRATION UNDER RULE 415.
 
        (a) Pursuant to its obligations under the Merger Agreement, the Company
    has agreed (i) to prepare and file with the SEC a registration statement on
    Form S-4 registering (x) the issuance of the Parent Common Stock issued in
    the Merger and (y) the resale of Parent Common Stock held by those holders
    listed on Schedule B herein (the "Shelf Holders") under Rule 415 of the
    Securities Act, and (ii) to prepare and file with the SEC a registration
    statement on Form S-3 registering the resale of Parent Common Stock held by
    the Shelf Holders under Rule 415 of the Securities Act following the Closing
    (the resale component of such registration statement on Form S-4 is referred
    to herein as the "Shelf Registration Statement," and at such time as the
    registration statement on Form S-3 referred to in this Section 1.5(a) is
    declared effective by the SEC, such Form S-3 shall be referred to herein as
    the "Shelf Registration Statement"). The Shelf Registration Statement shall
    register the resale of up to one million (1,000,000) shares of Parent Common
    Stock held by the Shelf Holders. The Company shall use its best efforts to
    have the registration statement on Form S-4 referred to in this Section
    1.5(a) declared effective by the SEC as soon as practicable in connection
    with the Closing of the Merger. The Company also shall use its best efforts
    to have the registration statement on Form S-3 referred to in this Section
    1.5(a) filed and declared effective by the SEC as soon as practicable
    following the Closing of the Merger. Until such time as the registration
    statement on Form S-3 referred to in this Section 1.5(a) is declared
    effective by the SEC, the Shelf Holders shall be entitled to rely on the
    registration statement on Form S-4 for the resale of shares of Parent Common
    Stock pursuant to the terms of this Agreement. At and from such time as the
    registration statement on Form S-3 referred to in this Section 1.5(a) is
    declared effective by the SEC, the Shelf Holders agree that they will not
    use the registration statement on Form S-4 referred to in this Section
    1.5(a) for the resale of Parent Common Stock and will only use the
    registration statement on Form S-3 referred to in this Section 1.5(a) for
    the resale of Parent Common Stock pursuant to the terms of this Agreement.
 
        (b) The Shelf Holders agree that the Shelf Registration Statement may be
    used by any of the Shelf Holders for the resale of Parent Common Stock on no
    more than two occasions and on each occasion, the Shelf Holders must resell
    at least two hundred fifty thousand (250,000) shares of Parent Common Stock.
    Upon the occasion of a total of two transactions by any Shelf Holder in
    which Parent Common Stock is sold pursuant to the Shelf Registration
    Statement, the right of all Shelf Holders to resell shares of Parent Common
    Stock under the Shelf Registration Statement shall terminate, unless such
    right has otherwise previously terminated as provided herein. In the event
    the Shelf Holders use the registration statement on Form S-4 referred to in
    Section 1.5(a) hereof (i) in one transaction, the Shelf Holders shall only
    be entitled to use the Shelf Registration Statement for one additional
    transaction, either on Form S-4 or on Form S-3, respectively, as referred to
    in Section 1.5(a), and (ii) in two transactions, the Shelf Holders shall not
    be entitled to use the registration statement on Form S-3 referred to in
    Section 1.5(a) hereof, and, if it has not already done so, the Company shall
    not be obligated to have such registration statement on Form S-3 declared
    effective or otherwise keep such registration statement effective, as
    applicable. The Shelf Holders also agree to provide the Company with five
    (5) days prior written notice of any resale by them of Parent Common Stock
    pursuant to the Shelf Registration Statement.
 
                                     A-A-6
<PAGE>
        (c) The Company shall keep the Shelf Registration Statement effective
    pursuant to Rule 415, and, subject to Section 1.5(b) above, the Shelf
    Holders will have the right to use the Shelf Registration Statement, at all
    times until the earlier of (i) the date the Shelf Holders have sold in the
    aggregate at least one million shares (1,000,000) of Parent Common Stock
    pursuant to the Shelf Registration Statement, (ii) the date the Shelf
    Holders have sold in the aggregate, under this Agreement and under any other
    sale permitted by the Securities Act, the lesser of two million shares
    (2,000,000) of Parent Common Stock or that number of shares of Parent Common
    Stock which has resulted in the Shelf Holders receiving in the aggregate
    (before deduction of commissions and other Selling Expenses) at least sixty
    million dollars ($60,000,000) of consideration, or (iii) one year from the
    Effective Time as defined in the Merger Agreement.
 
        (d) Except as otherwise provided in Subsection 1.5(b), the Shelf
    Holders' right to use the Shelf Registration Statement to effect the resale
    of Parent Common Stock shall be suspended on a date specified in writing by
    the managing underwriter in connection with any underwritten public offering
    of the Company's Common Stock made pursuant to Sections 1.3 or 1.4 of this
    Agreement, and shall resume on the date the Shelf Holders are no longer
    subject to any lockup provisions pursuant to such underwriting so long as
    the Shelf Holders are still entitled to use the Shelf Registration Statement
    pursuant to Section 1.5(c) above.
 
        (e) The Shelf Holders agree not to transfer, sell, exchange, pledge or
    otherwise dispose of or encumber (except as may be specifically required by
    court order) any shares of Parent Common Stock under the Shelf Registration
    Statement, or to make any offer or agreement relating thereto, at any time
    from the date of this Agreement until after the Expiration Date.
 
        (f) The Company may by written notice (a "Shelf Blackout Right") require
    that the Shelf Holders immediately cease sales of shares (for a period not
    to exceed sixty (60) days) pursuant to the Shelf Registration Statement at
    any time that (i) the Company becomes engaged in business activity or
    negotiation which is not disclosed in the Shelf Registration Statement (or
    the prospectus included therein) which the Company reasonably believes must
    be disclosed therein under applicable law and which the Company desires to
    keep confidential for business purposes, (ii) the Company determines that a
    particular disclosure so determined to be required to be disclosed therein
    would be premature or would adversely affect the Company or its business or
    prospects, or (iii) the Shelf Registration Statement can no longer be used
    under the existing rules and regulations promulgated under the Securities
    Act. The Company shall not be required to disclose to the Holders which of
    the reasons specified in clauses (i), (ii) or (iii) above are the basis for
    requiring a suspension of sales hereunder. Notwithstanding the foregoing,
    until the elapse of the Restricted Period, the Company may only exercise the
    Shelf Blackout Right based upon (x) the good faith judgment of the Board of
    Directors pursuant to their fiduciary obligations as a result of an action
    initiated by a party other than the Company (and not including an
    acquisition, merger or other business combination pursuant to which the
    Company will acquire or otherwise be the surviving entity in a combination
    or reorganization with another company (not including companies which are
    controlled by the Company as of the date of this Agreement) or negotiations
    or discussions with respect thereto), or (y) the advice of counsel that the
    exercise of such Shelf Blackout Right is necessary in order to enable the
    Company to amend the registration statement to comply with the existing
    rules and regulations promulgated under the Securities Act. In the event
    that during the Restricted Period the exercise of the Shelf Blackout Right
    is necessary to amend the registration statement to comply with existing
    rules and regulations under the Securities Act, the Company shall use
    reasonable efforts to promptly make such amendment; provided, that during
    such Restricted Period the Company shall file such necessary amendment to
    the registration statement no later than fifteen (15) days from the date the
    Holders are provided notice of the need to exercise such Shelf Blackout
    Right. In the event the Holders elect to be included in an underwritten
    public offering pursuant to a Registration Opportunity but are unable due to
    market conditions to sell in the aggregate that number of shares of
    Registrable Securities equal to the
 
                                     A-A-7
<PAGE>
    Underwriter's Cutback Threshold (including in the calculation of such
    Threshold all prior sales of Registrable Securities by all Holders), the
    foregoing limitations on the Company's ability to exercise a Shelf Blackout
    Right shall continue to apply to the Company's Shelf Blackout Right.
 
    1.6  EXPENSES OF REGISTRATION.  The Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 1.3, 1.4 and 1.5 shall be borne by the Company. All Selling Expenses
incurred in connection with Sections 1.3, 1.4 and 1.5 shall be borne by the
Holders of the securities so registered PRO RATA on the basis of the number of
their shares so registered.
 
    1.7  OBLIGATIONS OF THE COMPANY.  Whenever required to effect the
registration of any Registrable Securities under this Agreement, the Company
shall, as expeditiously as reasonably possible:
 
        (a) Prepare and file with the SEC a registration statement with respect
    to such Registrable Securities and use its best efforts to cause such
    registration statement to become effective, and keep such registration
    statement effective until the distribution is completed, but not longer than
    ninety (90) days after the effective date thereof (excluding any days in
    which the Company requires the Holders to cease sales of shares as provided
    below); provided, however, that the Company may by written notice (a
    "Blackout Right") require that the Holders immediately cease sales of shares
    (for a period not to exceed sixty (60) days) pursuant to such Registration
    Statement at any time that (i) the Company becomes engaged in business
    activity or negotiation which is not disclosed in the Registration Statement
    (or the prospectus included therein) which the Company reasonably believes
    must be disclosed therein under applicable law and which the Company desires
    to keep confidential for business purposes, (ii) the Company determines that
    a particular disclosure so determined to be required to be disclosed therein
    would be premature or would adversely affect the Company or its business or
    prospects, or (iii) the registration statement can no longer be used under
    the existing rules and regulations promulgated under the Securities Act. The
    Company shall not be required to disclose to the Holders which of the
    reasons specified in clauses (i), (ii) or (iii) above are the basis for
    requiring a suspension of sales hereunder. Notwithstanding the foregoing,
    until the elapse of the Restricted Period, the Company may only exercise the
    Blackout Right based upon (x) the good faith judgment of the Board of
    Directors pursuant to their fiduciary obligations as a result of an action
    initiated by a party other than the Company (and not including an
    acquisition, merger or other business combination pursuant to which the
    Company will acquire or otherwise be the surviving entity in a combination
    or reorganization with another company (not including companies which are
    controlled by the Company as of the date of this Agreement) or negotiations
    or discussions with respect thereto), or (y) the advice of counsel that the
    exercise of such Blackout Right is necessary in order to enable the Company
    to amend the registration statement to comply with the existing rules and
    regulations promulgated under the Securities Act. In the event that during
    the Restricted Period the exercise of the Blackout Right is necessary to
    amend the registration statement to comply with existing rules and
    regulations under the Securities Act, the Company shall use reasonable
    efforts to promptly make such amendment; provided, that the Company shall
    during such Restricted Period file such necessary amendment to the
    registration statement no later than fifteen (15) days from the date the
    Holders are provided notice of the need to exercise such Blackout Right. In
    the event the Holders elect to be included in an underwritten public
    offering pursuant to a Registration Opportunity but are unable due to market
    conditions to sell in the aggregate that number of shares of Registrable
    Securities equal to the Underwriter's Cutback Threshold (including in the
    calculation of such Threshold all prior sales of Registrable Securities by
    all Holders), the foregoing limitations on the Company's ability to exercise
    a Blackout Right shall continue to apply to the Company's Blackout Right.
 
        (b) Prepare and file with the SEC such amendments and supplements to
    such registration statement and the prospectus used in connection with such
    registration statement as may be necessary to comply with the provisions of
    the Securities Act with respect to the disposition of all securities covered
    by such registration statement.
 
                                     A-A-8
<PAGE>
        (c) Furnish to the Holders such number of copies of a prospectus,
    including a preliminary prospectus, in conformity with the requirements of
    the Securities Act, and such other documents as they may reasonably request
    in order to facilitate the disposition of the Registrable Securities owned
    by them that are included in such registration.
 
        (d) Use its best efforts to register and qualify the securities covered
    by such registration statement under such other securities or Blue Sky laws
    of such jurisdictions as shall be reasonably requested by the Holders,
    PROVIDED, HOWEVER, that the Company shall not be required in connection
    therewith or as a condition thereto to qualify to do business or to file a
    general consent to service of process in any such states or jurisdictions.
 
        (e) Enter into and perform its obligations under an underwriting
    agreement, in usual and customary form, with the managing underwriter(s) of
    such offering. Each Holder participating in such underwriting shall also
    enter into and perform its obligations under such an agreement.
 
        (f) Notify each Holder of Registrable Securities covered by such
    registration statement at any time when a prospectus relating thereto is
    required to be delivered under the Securities Act of the happening of any
    event as a result of which the prospectus included in such registration
    statement, as then in effect, includes an untrue statement of a material
    fact or omits to state a material fact required to be stated therein or
    necessary to make the statements therein not misleading in the light of the
    circumstances then existing.
 
        (g) Furnish, at the request of any Holder registering Registrable
    Securities, on the date that such Registrable Securities are delivered to
    the underwriters for sale, (i) an opinion, dated as of such date, of the
    counsel representing the Company for the purposes of such registration, in
    form and substance as is customarily given in the opinion of issuer's
    counsel addressed to each of the underwriters and the participating Holders,
    and (ii) a "comfort" letter dated as of such date, from the independent
    certified public accountants of the Company, in form and substance as is
    customarily given by independent certified public accountants to
    underwriters in an underwritten public offering addressed to the
    underwriters.
 
    1.8  FURNISH INFORMATION.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 1.3, 1.4 or
1.5 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of Registrable Securities.
 
    1.9  DELAY OF REGISTRATION.  No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Agreement.
 
    1.10  INDEMNIFICATION.  In the event any Registrable Securities are included
in a registration statement under Sections 1.3, 1.4 or 1.5:
 
        (a)  BY THE COMPANY.  To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, the partners, officers and directors of
each Holder, any underwriter (as defined in the Securities Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Securities Act or the Exchange Act against any losses, claims,
damages, or liabilities to which they may become subject under the Securities
Act, the Exchange Act or other federal or state law, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereof) arise out of or
are based upon any of the following statements, omissions or violations
(collectively a "Violation"):
 
            (i) any untrue statement or alleged untrue statement of a material
       fact contained in such registration statement, including any preliminary
       prospectus or final prospectus contained therein or any amendments or
       supplements thereto;
 
                                     A-A-9
<PAGE>
            (ii) the omission or alleged omission to state therein a material
       fact required to be stated therein, or necessary to make the statements
       therein, in light of the circumstances in which made, not misleading, or
 
           (iii) any violation or alleged violation by the Company of the
       Securities Act, the Exchange Act, any federal or state securities law or
       any rule or regulation promulgated under the Securities Act, the Exchange
       Act or any federal or state securities law in connection with the
       offering covered by such registration statement;
 
       and the Company will reimburse each such Holder, partner, officer or
       director, underwriter or controlling person for any legal or other
       expenses reasonably incurred by them, as incurred, in connection with
       investigating or defending any such loss, claim, damage, liability or
       action; PROVIDED, HOWEVER, that the indemnity agreement contained in this
       subsection 1.10(a) shall not apply to amounts paid in settlement of any
       such loss, claim damage, liability or action if such settlement is
       effected without the consent of the Company (which consent shall not be
       unreasonably withheld), nor shall the Company be liable in any such case
       for any such loss, claim, damage, liability or action to the extent that
       it arises out of or is based upon a Violation which occurs in reliance
       upon and in conformity with written information furnished, expressly for
       use in connection with such registration by such Holder, partner,
       officer, director, underwriter or controlling person of such Holder.
 
        (b)  BY SELLING HOLDERS.  To the extent permitted by law, each selling
Holder will indemnify and hold harmless the Company, each of its directors, each
of its officers who have signed the registration statement, each person, if any,
who controls the Company within the meaning of the Securities Act, any
underwriter (as defined in the Securities Act) and any other Holder selling
securities under such registration statement or any of such other Holder's
partners, directors or officers or any person who controls such underwriter or
other Holder within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, underwriter or
other such Holder, partner or director, officer or controlling person of such
underwriter or other Holder may become subject under the Securities Act, the
Exchange Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereto) arise out of or are based
upon any Violation, in each case to the extent (and only to the extent) that
such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or other Holder, partner, officer, director or controlling
person of such other Holder or underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER,
that the indemnity agreement contained in this subsection 1.10(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the written consent of the
Holder, which consent shall not be unreasonably withheld; and PROVIDED FURTHER,
that the total amounts payable in indemnity by a Holder under this subsection
1.10(b) in respect of any Violation shall not exceed the net proceeds received
by such Holder in the registered offering out of which such Violation arises.
 
        (c)  NOTICE.  Promptly, but in no event later than thirty (30) days,
after receipt by an indemnified party under Section 1.10 of notice of the
commencement of any action (including, without limitation, any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under Section 1.10, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; PROVIDED, HOWEVER, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying
 
                                     A-A-10
<PAGE>
party would be inappropriate due to actual or potential conflict of interests
between such indemnified party and any other party represented by such counsel
in such proceeding, and PROVIDED FURTHER, that the indemnifying party shall not
be required to pay for more than one separate counsel for all indemnified
parties. The failure to deliver written notice to the indemnifying party within
thirty (30) days of the commencement of any such action, if materially
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under Section 1.10,
but the omission so to deliver written notice to the indemnifying party will not
relieve it of any liability that it may have to any indemnified party otherwise
than under Section 1.10.
 
        (d)  CONTRIBUTION.  In order to provide for just and equitable
contribution to joint liability under the Securities Act in any case in which
either (i) any Holder exercising rights under this Agreement, or any controlling
person of any such Holder, makes a claim for indemnification pursuant to Section
1.10 but it is judicially determined (by the entry of a final judgment or decree
by a court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that Section 1.10 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling Holder or any such controlling
person in circumstances for which indemnification is provided under Section
1.10; then, and in each such case, the Company and such Holder will contribute
to the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportion as is appropriate to
reflect the relative fault of the indemnifying party or parties on the one hand
and the indemnified party on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities, as well
as any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the indemnifying party or
parties on the one hand or the indemnified party on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission; PROVIDED, HOWEVER, that in any such
case, (A) no such Holder will be required to contribute any amount in excess of
the net proceeds received by such holder from all such Registrable Securities
offered and sold by such Holder pursuant to such registration statement; and (B)
no person or entity guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any person or entity who was not guilty of such fraudulent misrepresentation.
The amount paid or payable by a contributing party as a result of the losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
referred to above in this Section 1.10 shall include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.
 
        (e)  SURVIVAL.  The obligations of the Company and Holders under Section
1.10 shall survive the completion of any offering of Registrable Securities in a
registration statement.
 
    1.11  "MARKET STAND-OFF" AGREEMENT.  Each Holder who gives notice to the
Company of such Holder's desire to participate in any registration under Section
1.3 or 1.4 hereof hereby agrees that it shall not, to the extent requested by
the Company or the managing underwriter, sell or otherwise transfer or dispose
of any Registrable Securities or other shares of stock of the Company then owned
by such Holder (other than to donees, affiliates or partners of the Holder who
agree to be similarly bound) for the period from the filing of the registration
statement until up to ninety (90) days following the date of the final
prospectus in connection with the registration statement; provided, however,
that such agreement shall not be applicable to Registrable Securities sold
pursuant to such registration statement.
 
    In the case of an underwritten offering under Section 1.3 hereof, the
Company shall refrain, without the consent of the managing underwriter, for a
period from fifteen (15) days before the effective date of the registration sale
until ninety (90) days after such effective date, from directly or indirectly
selling, offering to sell (excluding any shares offered for sale pursuant to a
Form S-4), granting any option for the
 
                                     A-A-11
<PAGE>
sale of, or otherwise disposing of any common equity or securities convertible
into common equity other than pursuant to Company employee equity plans.
 
    In order to enforce the foregoing covenant, the Company shall have the right
to place restrictive legends on the certificates representing the shares subject
to this Section 1.11 and to impose stop transfer instructions with respect to
the Registrable Securities of such Holders until the end of such period. The
provisions of this Section 1.11 shall be binding upon any transferee of any
Registrable Securities.
 
    1.12  TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the Company to
register securities granted Holders under Sections 1.3 and 1.4 may be assigned
to any constituent partner of a Holder, where such Holder is a partnership, or
to any parent or subsidiary corporation or any officer, director or principal
stockholder thereof, where such Holder is a corporation, provided that (i) such
transfer may otherwise be effected in accordance with the applicable securities
laws, and (ii) the Company is given written notice of such assignment prior to
such assignment.
 
    1.13  TERMINATION OF RIGHTS.  Except as otherwise provided, the rights
granted pursuant to this Agreement (a) shall terminate as to any Holder when the
aggregate number of Registrable Securities which such Holder holds (together
with other Holders whose sales may be aggregated) could all be sold in a public
sale in compliance with Rule 144 under the Securities Act using the 1% volume
limitation contained in Rule 144(e)(1)(i), and (b) shall not be exercisable by
any Holder if at the time of the request for or notice of registration under
Section 1.3 and 1.4 such Holder could sell (together with other Holders whose
sales may be aggregated) in a three (3) month period all Registrable Securities
then held by such Holder in compliance with Rule 144 using the Company's average
weekly trading volume calculation at such time; provided, a Holder's rights
under Section 1.4 shall not be suspended until such time as the Holder is able
to sell (together with other Holders whose sales may be aggregated) in a three
(3) month period all Registrable Securities then held by such Holder in
compliance with Rule 144 but based on a calculation of the Company's average
weekly trading volume equal to fifty percent (50%) of the Company's actual
average weekly trading volume.
 
    1.14  RULE 144 REPORTING.  With a view to make available the benefits of
Rule 144 the Company agrees to:
 
        (a) make and keep public information available, as those terms are
    understood and defined in Rule 144 under the Securities Act;
 
        (b) use its best efforts to file with the SEC in a timely manner all
    reports and other documents required of the Company under the Securities Act
    and the Exchange Act; and
 
        (c) furnish to the Holder forthwith upon request a written statement by
    the Company as to its compliance with the reporting requirements of Rule
    144, and provide a copy of the most recent annual or quarterly report of the
    Company, and such other reports and documents of the Company as a Holder may
    reasonably request in availing itself of Rule 144.
 
                                   SECTION 2
                                 MISCELLANEOUS
 
    2.1  WAIVERS AND AMENDMENTS.  The rights and obligations of the Company and
the rights and obligations of a Holder under this Agreement may be waived

prospectively, and either for a specified period of time or indefinitely) or
amended, only with the written consent of the Company and the holders of at
least 50% of the number of outstanding number of shares of Registrable
Securities.
 
    2.2  GOVERNING LAW.  This Agreement shall be governed by and construed under
the laws of the State of Delaware as such laws are applied to contracts made and
to be fully performed entirely within that
 
                                     A-A-12

state between residents of that state. All disputes arising out of this
Agreement shall be subject to the exclusive jurisdiction and venue of the

consent to the personal and exclusive jurisdiction and venue of these courts.

the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto.

understanding and agreement between the parties with regard to the subjects
hereof and thereof.

hereunder shall be in writing and shall be mailed by first class, postage
prepaid, addressed (a) if to a Holder, at such Holder's address set forth in
Schedule A hereto, or at such other address as such Holder shall have furnished

offices (Attention: Chief Financial Officer) or at such other address as the
Company shall have furnished to the Holders in writing. Notices shall be
effective upon mailing.
 
    2.6  SEVERABILITY.  In case any provision of this Agreement shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions of this Agreement shall not in any way be affected or
impaired thereby.

                           AFFILIATE/VOTING AGREEMENT
 
    THIS AFFILIATE/VOTING AGREEMENT (this "AGREEMENT") is made and entered into
as of February 13, 1998, by and among Access Health, Inc., a Delaware
corporation ("PARENT"), InterQual, Inc., a Delaware corporation (the "COMPANY"),
and the undersigned stockholder who may be deemed an affiliate ("AFFILIATE") of
the Company. Capitalized terms used but not otherwise defined herein shall have
the meanings ascribed to them in the Reorganization Agreement (as defined
below).
 
                                    RECITALS
 
        A. The Company, Merger Sub (as defined below) and Parent have entered
into an Agreement and Plan of Reorganization (the "REORGANIZATION AGREEMENT")
which contemplates that the Company and a wholly-owned subsidiary of Parent
("MERGER SUB") will enter into an Agreement of Merger, which Agreements
(collectively, the "MERGER AGREEMENTS") provide for the merger (the "MERGER") of
Merger Sub with and into the Company. Pursuant to the Merger, all outstanding
capital stock of the Company will be converted into Common Stock of Parent.
 
        B.  Affiliate is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of such
number of shares of the outstanding Company capital stock as is indicated on the
final page of this Agreement, which shares shall be exchanged for shares of
Common Stock of Parent as a result of the Merger (for purposes of this Agreement
"SHARES" means shares of Company capital stock and the shares of Common Stock of
Parent issued in exchange therefor as a result of the Merger).
 
        C.  Affiliate understands that, since the Merger will be accounted for
using the "pooling of interests" method and Affiliate may be deemed to be an
"affiliate" of the Company (within the meaning of Securities and Exchange
Commission ("SEC") Rule 145), the Shares may only be disposed of in conformity
with the limitations described herein. Affiliate has been informed that the
treatment of the Merger as a pooling of interests for accounting purposes, and
as a tax-free reorganization under applicable provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), is dependent upon the accuracy of certain
of the representations and warranties and the compliance with certain of the
agreements set forth herein. Affiliate further understands that the
representations, warranties and agreements set forth herein will be relied upon
by Parent, the Company and their respective counsel and accounting firms.
 
    NOW THEREFORE, the parties agree as follows:
 
    1.  AGREEMENT TO RETAIN SHARES.
 
        (a)  TRANSFER AND ENCUMBRANCE.  Affiliate agrees not to transfer, sell,
exchange, pledge or otherwise dispose of or encumber (except as may be
specifically required by court order) the Shares, any shares of Common Stock of
Parent, or any New Shares (as defined in Section 1(b) below) or to make any
offer or agreement relating thereto, at any time from the date of this Agreement
until the Expiration Date. As used herein, the term "EXPIRATION DATE" shall mean
the date Parent shall have published (in accordance with applicable "pooling of
interests" accounting rules) the combined financial results of Parent and the
Company for a period of at least 30 days of combined operations of Parent and
the Company.
 
        (b)  NEW SHARES.  Affiliate agrees that any shares of capital stock of
the Company and/or Parent that Affiliate purchases or with respect to which
Affiliate otherwise acquires beneficial ownership after the date of this
Agreement and prior to the Expiration Date ("NEW SHARES") shall be subject to
the terms and conditions of this Agreement to the same extent as if they
constituted Shares.
 
    2.  AGREEMENT TO VOTE SHARES.  At every meeting of the stockholders of the
Company called with respect to any of the following, and at every adjournment
thereof, and on every action or approval by
 
                                    A-B-1-1
<PAGE>
written consent of the stockholders of the Company with respect to any of the
following, Affiliate shall vote the Shares and any New Shares: (i) in favor of
approval of the Merger Agreements and the Merger and any matter that could
reasonably be expected to facilitate the Merger (including without limitation
the conversion, if reasonably necessary, of any shares of Preferred Stock of the
Company into Common Stock of the Company immediately prior to or at the
effective time of the Merger, consistent with the provisions of the Company's
Certificate of Incorporation and with the requirements necessary to account for
the Merger as a "pooling-of-interests"); and (ii) against approval of any
proposal made in opposition to or in competition with consummation of the Merger
and against any merger, consolidation, sale of assets, reorganization or
recapitalization, with any party other than with Parent and its affiliates and
against any liquidation or winding up of the Company (each of the foregoing is
hereinafter referred to as an "OPPOSING PROPOSAL"). Affiliate agrees not to take
any actions contrary to Affiliate's obligations under this Agreement.
 
    3.  IRREVOCABLE PROXY.  Concurrently with the execution of this Agreement,
Affiliate agrees to deliver to Parent a proxy in the form attached hereto as
Exhibit A (the "PROXY"), which shall be irrevocable to the extent permitted by
Section 212(e) of the General Corporation Law of the State of Delaware, with
respect to the total number of shares of capital stock of the Company
beneficially owned (as such term is defined in Rule 13d-3 under the Exchange
Act) by Affiliate set forth therein.
 
    4.  TAX TREATMENT: RULE 145.  Affiliate understands and agrees that it is
intended that the Merger qualify as a "reorganization" under Section 368 of the
Code. Affiliate further understands and agrees that Affiliate may be deemed to
be an "affiliate" of the Company within the meaning of Rule 145 ("RULE 145")
promulgated by the SEC under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), although nothing contained herein should be construed as an
admission of such fact.

the Securities Act, Parent will use its best efforts to file on a timely basis
all reports required to be filed by it pursuant to Section 13 of the Exchange
Act referred to in paragraph (c)(l) of Rule 144 under the Securities Act (or, if
applicable, Parent will use its best efforts to make publicly available the
information regarding itself referred to in paragraph (c)(2) of Rule 144), in
order to permit Affiliate to sell the Parent Common Stock held by it pursuant to
the terms and conditions of Rule 145 and the applicable provisions of Rule 144.
 
        (b) Parent agrees that Affiliate may make use of any "de minimis"
exceptions to the pooling of interest requirements.
 
    8.  LIMITED RESALES.  Affiliate understands that, in addition to the
restrictions imposed under Section 6 of this Agreement, the provisions of Rule
145 currently limit Affiliate's public resales of Restricted Securities, in the
manner set forth in subsections (a), (b) and (c) below:
 
        (a) Unless and until the restriction "Cut-off" provisions of Rule
145(d)(2) or Rule 145(d)(3) set forth below become available, public resales of
Restricted Securities may only be made by Affiliate in compliance with the
requirements of Rule 145(d)(1). Rule 145(d)(1) permits such resales only: (i)
while Parent meets the public information requirements of Rule 144(c); (ii) in
broker's transactions or in transactions with a market maker; and (iii) where
the aggregate number of Restricted Securities sold at any time together with all
sales of restricted Parent Common Stock sold for Affiliate's account during the
preceding three-month period does not exceed the greater of (A) one percent (1%)
of the Parent Common Stock outstanding or (B) the average weekly volume of
trading in Parent Common Stock on all national securities exchanges, as reported
through the automated quotation system of a registered securities association,
during the four (4) calendar weeks preceding the date of receipt of the order to
execute the sale.
 
        (b) Affiliate may make unrestricted sales of Restricted Securities
pursuant to Rule 145(d)(2) if: (i) Affiliate has beneficially owned (within the
meaning of Rule 144(d) under the Securities Act) the Restricted Securities for
at least one (1) year after the Effective Time of the Merger; (ii) Affiliate is
not an affiliate of Parent; and (iii) Parent meets the public information
requirements of Rule 144(c).
 
        (c) Affiliate may make unrestricted resales of Restricted Securities
pursuant to Rule 145(d)(3) if Affiliate has beneficially owned (within the
meaning of Rule 144(d) under the Securities Act) the Restricted Securities for
at least two (2) years and is not, and has not been for at least three (3)
months, an affiliate of Parent.
 
        (d) Parent acknowledges that the provisions of Section 6(c) of this
Agreement will be satisfied as to any sale by the undersigned of the Restricted
Securities pursuant to Rule 145(d), by a broker's letter and
 
                                    A-B-1-3
<PAGE>
a letter from the undersigned with respect to that sale stating that each of the
above-described requirements of Rule 145(d)(1) has been met or is inapplicable
by virtue of Rule 145(d)(2) or Rule 145(d)(3) (as such Rules may be in effect at
such time); provided, however, that Parent has no reasonable basis to believe
that such sales were not made in compliance with such provisions of Rule 145(d).
 
    9.  LEGENDS.  Affiliate also understands and agrees that stop transfer
instructions will be given to Parent's transfer agent with respect to
certificates evidencing the Restricted Securities and that there will be placed
on the certificate evidencing the Restricted Securities legends stating in
substance:
 
    "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
    WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
    APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,
    SOLD, PLEDGED, EXCHANGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
    ACCORDANCE WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AND THE
    OTHER CONDITIONS SPECIFIED IN THAT CERTAIN AFFILIATE/ VOTING AGREEMENT DATED
    AS OF FEBRUARY 13, 1998 AMONG ACCESS HEALTH, INC., INTERQUAL, INC. AND THE
    STOCKHOLDER, A COPY OF WHICH AFFILIATE/ VOTING AGREEMENT MAY BE INSPECTED BY
    THE HOLDER OF THIS CERTIFICATE AT THE PRINCIPAL OFFICES OF ACCESS HEALTH,
    INC."
 
After the Expiration Date, Parent agrees to remove the above legend, and replace
such legend with the following legend stating in substance:
 
    "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED, SOLD,
    PLEDGED, EXCHANGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
    ACCORDANCE WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS
    AMENDED.".
 
Parent agrees to remove promptly such stop transfer instructions and legend upon
full compliance with this Agreement by the undersigned, including, without
limitation, a sale or transfer of Parent Common Stock permitted under Section
6(c) above.
 
    10.  TERMINATION.  This Agreement shall be terminated and shall be of no
further force and effect in the event of the termination of the Reorganization
Agreement pursuant to Article VIII of the Reorganization Agreement.
 
    11.  PARTNERSHIP DISTRIBUTIONS.  Any other provisions of this Agreement
notwithstanding, if the undersigned Affiliate is organized as a partnership, the
Company and Parent hereby agree that such partnership shall be permitted to make
a distribution to its partners of shares of Company capital stock (if made prior
to the effectiveness of the Merger) or of shares of Parent capital stock
received in the Merger so long as the undersigned Affiliate and its partnership
distributees provide assurances, acceptable to Parent and the Company in their
reasonable discretion, that such distributions (i) are permissible under Rule
145, (ii) will not prevent the Merger from being treated as a tax-free
reorganization for federal income tax purposes, or (iii) will not prevent the
Merger from being accounted for as a pooling of interests.
 
    12.  MISCELLANEOUS.
 
        (a)  COUNTERPARTS.  This Agreement shall be executed in one or more
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.
 
        (b)  BINDING AGREEMENT.  This Agreement will inure to the benefit of and
be binding upon and enforceable against the parties and their successors and
assigns, including administrators, executors, representatives, heirs, legatees
and devisees of Affiliate and pledgees holding Restricted Securities as
collateral.
 
        (c)  WAIVER.  No waiver by any party hereto of any condition or of any
breach of any provision of this Agreement shall be effective unless in writing
and signed by each party hereto.

        (d)  GOVERNING LAW.  This Agreement shall be governed by and construed,
interpreted and enforced in accordance with the internal laws of the State of
Delaware, without giving effect to any choice or conflict of law provision or
rule (whether of the State of Delaware or any other jurisdiction) that would
cause the application of the laws of any jurisdiction other than the State of
Delaware.
 
        (e)  ATTORNEYS' FEES.  In the event of any legal actions or proceeding
to enforce or interpret the provisions hereof, the prevailing party shall be
entitled to reasonable attorneys' fees, whether or not the proceeding results in
a final judgment.

        (h)  INJUNCTIVE RELIEF.  Each of the parties acknowledge that (i) the
covenants and the restrictions contained in this Agreement are necessary,
fundamental, and required for the protection of Parent and the Company and to
preserve for Parent the benefits of the Merger; (ii) such covenants relate to
matters which are of a special, unique, and extraordinary character that gives
each of such covenants a special, unique, and extraordinary value; and (iii) a
breach of any such covenants or any other provision of this Agreement will
result in irreparable harm and damages to Parent and the Company which cannot be
adequately compensated by a monetary award. Accordingly, it is expressly agreed
that in addition to all other remedies available at law or in equity, Parent and
the Company shall be entitled to the immediate remedy of a temporary restraining
order, preliminary injunction, or such other form of injunctive or equitable
relief as may be used by any court of competent jurisdiction to restrain or
enjoin any of the parties hereto from breaching any such covenant or provision
or to specifically enforce the provisions hereof.

                               IRREVOCABLE PROXY
 
    The undersigned stockholder of InterQual, Inc., a Delaware corporation (the
"COMPANY") hereby irrevocably (to the full extent permitted by Section 212(e) of
the General Corporation Law of the State of Delaware) appoints the directors on
the Board of Directors of Access Health, Inc., a Delaware corporation
("PARENT"), and each of them, as the sole and exclusive attorneys and proxies of
the undersigned, with full power of substitution and resubstitution, to the full
extent of the undersigned's rights with respect to the shares of capital stock
of the Company beneficially owned by the undersigned, which shares are listed on
the final page of this Proxy (the "SHARES"), and any and all other shares or
securities issued or issuable in respect thereof on or after the date hereof,
until such time as that certain Agreement of Merger and Plan of Reorganization,
which contemplates that the Company and a wholly-owned subsidiary of Parent
("MERGER SUB") will enter into an Agreement of Merger, which Agreements (the

sale of assets, reorganization or recapitalization of the Company with any party
other than Parent and its affiliates, and against any liquidation or winding up

                              AFFILIATE AGREEMENT
 
    THIS AFFILIATE AGREEMENT (this "AGREEMENT") is made and entered into as of
February 13, 1998, by and among Access Health, Inc., a Delaware corporation
("PARENT"), InterQual, Inc., a Delaware corporation (the "COMPANY"), and the
undersigned stockholder who may be deemed an affiliate ("AFFILIATE") of the
Company. Capitalized terms used but not otherwise defined herein shall have the
meanings ascribed to them in the Reorganization Agreement (as defined below).
 
                                    RECITALS
 
        A. The Company, Merger Sub (as defined below) and Parent have entered
into an Agreement and Plan of Reorganization (the "REORGANIZATION AGREEMENT")
which contemplates that the Company and a wholly-owned subsidiary of Parent
("MERGER SUB") will enter into an Agreement of Merger, which Agreements
(collectively, the "MERGER AGREEMENTS") provide for the merger (the "MERGER") of
Merger Sub with and into the Company. Pursuant to the Merger, all outstanding
capital stock of the Company will be converted into Common Stock of Parent.
 
        B.  Affiliate is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of such
number of shares of the outstanding Company capital stock as is indicated on the
final page of this Agreement, which shares shall be exchanged for shares of
Common Stock of Parent as a result of the Merger (for purposes of this Agreement
"SHARES" means shares of Company capital stock and the shares of Common Stock of
Parent issued in exchange therefor as a result of the Merger).
 
        C.  Affiliate understands that, since the Merger will be accounted for
using the "pooling of interests" method and the Affiliate may be deemed to be an
"affiliate" of the Company (within the meaning of Securities and Exchange
Commission ("SEC") Rule 145), the Shares may only be disposed of in conformity
with the limitations described herein. Affiliate has been informed that the
treatment of the Merger as a pooling of interests for accounting purposes, and
as a tax-free reorganization under applicable provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), is dependent upon the accuracy of certain
of the representations and warranties and the compliance with certain of the
agreements set forth herein. Affiliate further understands that the
representations, warranties and agreements set forth herein will be relied upon
by Parent, the Company and their respective counsel and accounting firms.
 
    NOW THEREFORE, the parties agree as follows:
 
    1.  AGREEMENT TO RETAIN SHARES.
 
        (a)  TRANSFER AND ENCUMBRANCE.  Affiliate agrees not to transfer, sell,
exchange, pledge or otherwise dispose of or encumber (except as may be
specifically required by court order) the Shares, any shares of Common Stock of
Parent, or any New Shares, as defined in Section 1(b) below, or to make any
offer or agreement relating thereto, at any time from the date of this Agreement
until the Expiration Date. As used herein, the term "EXPIRATION DATE" shall mean
the date Parent shall have published (in accordance with applicable "pooling of
interests" accounting rules) the combined financial results of Parent and the
Company for a period of at least 30 days of combined operations of Parent and
the Company.
 
        (b)  NEW SHARES.  Affiliate agrees that any shares of capital stock of
the Company and/or Parent that Affiliate purchases or with respect to which
Affiliate otherwise acquires beneficial ownership after the date of this
Agreement and prior to the Expiration Date ("NEW SHARES") shall be subject to
the terms and conditions of this Agreement to the same extent as if they
constituted Shares.
 
    2.  TAX TREATMENT: RULE 145.  Affiliate understands and agrees that it is
intended that the Merger qualify as a "reorganization" under Section 368 of the
Code. Affiliate further understands and agrees that
 
                                    A-B-2-1
<PAGE>
Affiliate may be deemed to be an "affiliate" of the Company within the meaning
of Rule 145 ("RULE 145") promulgated by the SEC under the Securities Act of
1933, as amended (the "SECURITIES ACT"), although nothing contained herein
should be construed as an admission of such fact.
 
    3.  RELIANCE UPON REPRESENTATIONS, WARRANTIES AND COVENANTS.  Affiliate
understands that the representations, warranties and covenants of Affiliate set
forth herein will be relied upon by Parent, the Company and their respective
counsel and accounting firms.
 
    4.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF AFFILIATE.  Affiliate
represents, warrants and covenants as follows:
 
        (a) Affiliate has full power and authority to execute this Agreement, to
make the representations, warranties and covenants herein contained and to
perform Affiliate's obligations hereunder.
 
        (b) Set forth below the signatures below is the number of shares of
Company capital stock, and Parent Common Stock, owned by Affiliate, including
all Company capital stock and Parent Common Stock as to which Affiliate has sole
or shared voting or investment power and all rights, options and warrants to
acquire Company capital stock and Parent Common Stock owned or held by
Affiliate.
 
        (c) Except as may be specifically required by court order, Affiliate
will not sell, transfer, exchange, pledge or otherwise dispose of, or make any
offer or agreement relating to any of the foregoing with respect to, any shares
of Parent Common Stock that Affiliate owns or may acquire in connection with the
Merger, or any securities that may be paid as a dividend or otherwise
distributed thereon or with respect thereto or issued or delivered in exchange
or substitution therefor (all such shares and other securities of Parent are
sometimes collectively referred to as "RESTRICTED SECURITIES"), or any option,
right or other interest with respect to any Restricted Securities, unless: (i)
such transaction is permitted pursuant to Rule 145(d) under the Securities Act;
(ii) counsel representing Affiliate, which counsel is reasonably satisfactory to
Parent, shall have advised Parent in a written opinion letter satisfactory to
Parent and Parent's legal counsel, and upon which Parent and its legal counsel
may rely, that no registration under the Securities Act would be required in
connection with the proposed sale, transfer or other disposition; (iii) a
registration statement under the Securities Act covering the Parent Common Stock
proposed to be sold, transferred or otherwise disposed of, describing the manner
and terms of the proposed sale, transfer or other dispositions, and containing a
current prospectus, shall have been filed with the SEC and made effective under
the Securities Act; or (iv) an authorized representative of the SEC shall have
rendered written advice to Affiliate (sought by Affiliate or counsel to
Affiliate, with a copy thereof and all other related communications delivered to
Parent) to the effect that the SEC would take no action, or that the staff of
the SEC would not recommend that the SEC take any action, with respect to the
proposed disposition if consummated.
 
    5.  RULES 144 AND 145; POOLING.
 
        (a) From and after the Effective Time of the Merger and for so long as
is necessary in order to permit Affiliate to sell the Parent Common Stock held
by Affiliate pursuant to Rule 145 and, to the extent applicable, Rule 144 under
the Securities Act, Parent will use its best efforts to file on a timely basis
all reports required to be filed by it pursuant to Section 13 of the Exchange
Act referred to in paragraph (c)(l) of Rule 144 under the Securities Act (or, if
applicable, Parent will use its best efforts to make publicly available the
information regarding itself referred to in paragraph (c)(2) of Rule 144), in
order to permit Affiliate to sell the Parent Common Stock held by it pursuant to
the terms and conditions of Rule 145 and the applicable provisions of Rule 144.
 
        (b) Parent agrees that, Affiliate may makes use of any "de minimis"
exceptions to the pooling of interest requirements, Affiliate shall be entitled
to rely upon such exceptions to the same extent and in the same manner.
 
                                    A-B-2-2

    6.  LIMITED RESALES.  Affiliate understands that, in addition to the
restrictions imposed under Section 4 of this Agreement, the provisions of Rule
145 currently limit Affiliate's public resales of Restricted Securities, in the
manner set forth in subsections (a), (b) and (c) below:
 
        (a) Unless and until the restriction "Cut-off" provisions of Rule
145(d)(2) or Rule 145(d)(3) set forth below become available, public resales of
Restricted Securities may only be made by Affiliate in compliance with the
requirements of Rule 145(d)(1). Rule 145(d)(1) permits such resales only: (i)
while Parent meets the public information requirements of Rule 144(c); (ii) in

        (b) Affiliate may make unrestricted sales of Restricted Securities
pursuant to Rule 145(d)(2) if: (i) Affiliate has beneficially owned (within the
meaning of Rule 144(d) under the Securities Act) the Restricted Securities for
at least one (1) year after the Effective Time of the Merger; (ii) Affiliate is
not an affiliate of Parent; and (iii) Parent meets the public information
requirements of Rule 144(c).
 
        (c) Affiliate may make unrestricted resales of Restricted Securities
pursuant to Rule 145(d)(3) if Affiliate has beneficially owned (within the

at least two (2) years and is not, and has not been for at least three (3)
months, an affiliate of Parent.
 
        (d) Parent acknowledges that the provisions of Section 4(c) of this
Agreement will be satisfied as to any sale by the undersigned of the Restricted
Securities pursuant to Rule 145(d), by a broker's letter and a letter from the
undersigned with respect to that sale stating that each of the above-described
requirements of Rule 145(d)(1) has been met or is inapplicable by virtue of Rule
145(d)(2) or Rule 145(d)(3) (as such Rules may be in effect at such time);
provided, however, that Parent has no reasonable basis to believe that such
sales were not made in compliance with such provisions of Rule 145(d).
 
    7.  LEGENDS.  Affiliate also understands and agrees that stop transfer
instructions will be given to Parent's transfer agent with respect to
certificates evidencing the Restricted Securities and that there will be placed

    "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO
    WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
    APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED,

    STOCKHOLDER, A COPY OF WHICH AFFILIATE AGREEMENT MAY BE INSPECTED BY THE
    HOLDER OF THIS CERTIFICATE AT THE PRINCIPAL OFFICES OF ACCESS HEALTH, INC."
 
After the Expiration Date, Parent agrees to remove the above legend, and replace
such legend with the following legend stating in substance:
 
    "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED, SOLD,
    PLEDGED, EXCHANGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
    ACCORDANCE WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED."
 
                                    A-B-2-3
<PAGE>
Parent agrees to remove promptly such stop transfer instructions and legend upon
full compliance with this Agreement by the undersigned, including, without
limitation, a sale or transfer or Parent Common Stock permitted under Section

received in the Merger so long as the undersigned Affiliate and its partnership
distributees provide assurances, acceptable to Parent and the Company in their
reasonable discretion, that such distributions (i) are permissible under Rule
145, (ii) will not prevent the Merger from being treated as a tax-free
reorganization for federal income tax purposes, or (iii) will not prevent the
Merger from being accounted for as a pooling of interests.
 
    10.  MISCELLANEOUS.
 
        (a)  COUNTERPARTS.  This Agreement shall be executed in one or more
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.
 
        (b)  BINDING AGREEMENT.  This Agreement will inure to the benefit of and
be binding upon and enforceable against the parties and their successors and
assigns, including administrators, executors, representatives, heirs, legatees

breach of any provision of this Agreement shall be effective unless in writing
and signed by each party hereto.

fundamental, and required for the protection of Parent and the Company and to
preserve for Parent the benefits of the Merger; (ii) such covenants relate to

                           AFFILIATE/VOTING AGREEMENT
 
    THIS AFFILIATE/VOTING AGREEMENT (this "AGREEMENT") is made and entered into
as of February 13, 1998, by and among Access Health, Inc., a Delaware
corporation ("PARENT"), InterQual, Inc., a Delaware corporation (the "COMPANY"),
and the undersigned person who may be deemed an affiliate ("AFFILIATE") of
Parent. Capitalized terms used but not otherwise defined herein shall have the
meanings ascribed to them in the Reorganization Agreement (as defined below).
 
                                    RECITALS
 
        A. The Company, Merger Sub (as defined below) and Parent have entered
into an Agreement and Plan of Reorganization (the "REORGANIZATION AGREEMENT")
which contemplates that the Company and a wholly-owned subsidiary of Parent
("MERGER SUB") will enter into an Agreement of Merger, which Agreements
(collectively, the "MERGER AGREEMENTS") provide for the merger (the "MERGER") of
Merger Sub with and into the Company. Pursuant to the Merger, all outstanding
capital stock of the Company will be converted into Common Stock of Parent.
 
        B.  Affiliate is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of such
number of shares of the outstanding Parent capital stock as is indicated on the
final page of this Agreement (the "SHARES").
 
        C.  Affiliate understands that, since the Merger will be accounted for
using the "pooling of interests" method and Affiliate is an "affiliate" of
Parent (within the meaning of Securities and Exchange Commission ("SEC") Rule
145), the Shares may only be disposed of in conformity with the limitations
described herein. Affiliate has been informed that the treatment of the Merger
as a pooling of interests for accounting purposes, and as a tax-free
reorganization under applicable provisions of the Internal Revenue Code of 1986,
as amended the ("CODE"), is dependent upon the accuracy of certain of the
representations and warranties and the compliance with certain of the agreements
set forth herein. Affiliate further understands that the representations,
warranties and agreements set forth herein will be relied upon by Parent, the
Company and their respective counsel and accounting firms.
 
    NOW, THEREFORE, the parties agree as follows:
 
    1.  AGREEMENT TO RETAIN SHARES.
 
        (a)  TRANSFER AND ENCUMBRANCE.  Affiliate agrees not to transfer, sell,
exchange, pledge or otherwise dispose of or encumber (except as may be
specifically required by court order) the Shares or any New Shares (as defined
in Section 1(b) below) or to make any offer or agreement relating thereto, at
any time from the date of this Agreement until the Expiration Date. As used
herein, the term "EXPIRATION DATE" shall mean the date Parent shall have
published (in accordance with applicable "pooling of interests" accounting
rules) the combined financial results of Parent and the Company for a period of
at least 30 days of combined operations of Parent and the Company.
 
        (b)  NEW SHARES.  Affiliate agrees that any shares of capital stock of
Parent that Affiliate purchases or with respect to which Affiliate otherwise
acquires beneficial ownership after the date of this Agreement and prior to the
Expiration Date ("NEW SHARES") shall be subject to the terms and conditions of
this Agreement to the same extent as if they constituted Shares.
 
    2.  AGREEMENT TO VOTE SHARES.  At every meeting of the stockholders of
Parent called with respect to any of the following, and at every adjournment
thereof, and on every action or approval by written consent of the stockholders
of Parent with respect to any of the following, Affiliate shall vote the Shares
and any New Shares: (i) in favor of approval of the Merger Agreements and the
Merger and any matter that could reasonably be expected to facilitate the
Merger; and (ii) against approval of any proposal made in opposition to or
competition with consummation of the Merger (each of the foregoing is
hereinafter
 
                                    A-B-3-1
<PAGE>
referred to as an "OPPOSING PROPOSAL"). Affiliate agrees not to take any actions
contrary to Affiliate's obligations under this Agreement.
 
    3.  IRREVOCABLE PROXY.  Concurrently with the execution of this Agreement,
Affiliate agrees to deliver to Parent a proxy in the form attached hereto as
Exhibit A (the "PROXY"), which shall be irrevocable to the extent permitted by
Section 212 of the General Corporation Law of the State of Delaware, with
respect to the total number of shares of capital stock of Parent beneficially
owned (as such term is defined in Rule 13d-3 under the Exchange Act) by
Affiliate set forth therein.
 
    4.  TAX TREATMENT: RULE 145.  Affiliate understands and agrees that it is
intended that the Merger qualify as a "reorganization" under Section 368 of the
Code. Affiliate further understands and agrees that Affiliate may be deemed to
be an "affiliate" of Parent within the meaning of Rule 145 ("RULE 145")
promulgated by the SEC under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), although nothing contained herein should be construed as an
admission of such fact.
 
    5.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF AFFILIATE.  Affiliate
represents, warrants and covenants as follows:
 
        (a) Affiliate has full power and authority to execute this Agreement and
the Proxy, to make the representations, warranties and covenants herein
contained and to perform Affiliate's obligations hereunder.
 
        (b) Set forth below the signatures below is the number of shares of
Parent capital stock owned by Affiliate, including all Parent Common Stock as to

control to: (i) solicit proxies or become a "participant" in a "solicitation"
(as such terms are defined in Regulation 14A under the Exchange Act) with
respect to an Opposing Proposal or otherwise encourage or assist any party in
taking or planning any action that would compete with, restrain or otherwise
serve to interfere with or inhibit the timely consummation of the Merger in
accordance with the terms of the Merger Agreements; (ii) initiate a
stockholders' vote or action by consent of Parent stockholders with respect to
an Opposing Proposal; or (iii) become a member of a "group" (as such term is
used in Section 13(d) of the Exchange Act) with respect to any voting securities
of Parent with respect to an Opposing Proposal.
 
    6.  TERMINATION.  This Agreement shall be terminated and shall be of no
further force and effect in the event the termination of the Reorganization
Agreement pursuant to Article VIII of the Reorganization Agreement.
 
    7.  PARTNERSHIP DISTRIBUTIONS.  Any other provisions of this Agreement
notwithstanding, if the undersigned Affiliate is organized as a partnership, the
Company and Parent hereby agree that such partnership shall be permitted to make
a distribution to its partners of shares of Company capital stock (if made prior
to the effectiveness of the Merger) or of shares of Parent capital stock
received in the Merger so long as the undersigned Affiliate and its partnership
distributees provide assurances, acceptable to Parent and the Company in their
reasonable discretion, that such distributions (i) are permissible under Rule
145, (ii) will not prevent the Merger from being treated as a tax-free
reorganization for federal income tax purposes, or (iii) will not prevent the
Merger from being accounted for as a pooling of interests.
 
    8.  MISCELLANEOUS.
 
        (a)  COUNTERPARTS.  This Agreement shall be executed in one or more
counterparts, each of which shall be deemed an original, and all of which

            (i)  SEVERANCE PAYMENT.  The Company shall continue to pay to the
Executive his Base Compensation (the "Severance Payment") for the remainder of
the Initial Term (the "Severance Period"), plus any amounts to which Executive
is entitled under then-current Company policies; provided, however, that if the
termination occurs following a Change of Control, the Severance Payment shall be

be provided under applicable benefit plans and programs of the Company.

determined under the provisions of those plans and agreements, provided
Executive shall have three (3) months from the date of termination of employment
in which to exercise any non-qualified stock option and three (3) months from

each case to the extent such options are exercisable as of the date of
termination.
 
        (c)  TERMINATION ON DEATH.

                (C) acceleration of vesting of options as set forth on Exhibit A
attached hereto;
 
                (D) the continued right to exercise any vested stock option

and any other plan or program of the Company constitutes a "Parachute Payment,"
as such term is defined in Section 280G of the Internal Revenue Code of 1986
(the "Code"), and the amount of the Parachute Payment, reduced by all Federal,
state and local taxes applicable thereto, including, the excise tax imposed
pursuant to Section 4999 of the Code, is less than the amount the Executive
would receive, after taxes, if she were paid only three times his Base Amount as
defined in Section 280G(b)(3) of the Code less $1.00, then the payments to be

The determinations to be made with respect to this paragraph shall be made by
the public accounting firm that is retained by the Company as of the date
immediately prior to the Change in Control (the "Accounting Firm") which shall
provide detailed supporting calculations both to the Company and the Executive
within fifteen (15) business days of being requested to do so by the Company or
the Executive. In the event that the Accounting Firm is serving as accountant or
auditor for the individual, entity or group effecting the Change in Control, the
Executive shall appoint another nationally recognized public accounting firm to
make the determinations required hereunder (which accounting firm shall then be
referred to as the Accounting Firm hereunder). All fees and expenses of the
Accounting Firm shall be borne solely by the Company. The Executive shall be
responsible for payment of any excise tax imposed under Section 4999 of the Code
on any Parachute Payment as described in this Section.

            (i)  SEVERANCE PAYMENT.  The Company shall continue to pay to the
Consultant his Consulting Fee (the "Severance Payment") for the remainder of the
current term (the "Severance Period"); provided, however, that if the

Agreement occurs.
 
            (ii)  METHOD OF PAYMENT.  The Severance Payment shall be made in

Consultant's consultancy is terminated pursuant to Section 7(b)(ii) or
voluntarily pursuant to Section 7(c), no compensation or payments will be paid

termination of employment is effective. Notwithstanding the preceding sentence,
Consultant's rights under the benefit plans and option agreements of the Company
shall be determined under the provisions of those plans and agreements, provided
Consultant shall have three (3) months from the date of termination of the
consulting relationship in which to exercise any non-qualified stock option and
three (3) months from the date of termination of the consulting relationship to
exercise any incentive stock option in each case to the extent such options are

be) shall be promptly entitled to the Consulting Fee, at his then current rate,

provided, however, that if death follows a Change of Control, the amount of the
Severance Payment set forth in Section 8(a)(i) above.
 
        (d)  CODE SECTION 280G PAYMENTS.  Anything in this Agreement to the
contrary, if the aggregate of the amounts due the Consultant under this
Agreement and any other plan or program of the Company constitutes a "Parachute
Payment," as such term is defined in Section 280G of the Internal Revenue Code
of 1986 (the "Code"), and the amount of the Parachute Payment, reduced by all
Federal, state and local taxes applicable thereto, including, the excise tax
imposed pursuant to Section 4999 of the Code, is less than the amount the
Consultant would receive, after taxes, if she were paid only three times his
Base Amount as defined in Section 280G(b)(3) of the Code less $1.00, then the
payments to be made to the Consultant under this Agreement which are contingent
on a Change in Control shall be reduced to an amount which, when added to the
aggregate of all other payments to the Consultant which are contingent on a
Change in Control, will make the total amount of such payments equal to three
times his Base amount less $1.00. The determinations to be made with respect to
this paragraph shall be made by the public accounting firm that is retained by
the Company as of the date immediately prior to the Change in Control (the
"Accounting Firm") which shall provide detailed supporting calculations both to
the Company and the Consultant within fifteen (15) business days of being
requested to do so by the Company or the Consultant. In the event that the
Accounting Firm is serving as accountant or auditor for the individual, entity
or group effecting the Change in Control, the Consultant shall appoint another
nationally recognized public accounting firm to make the determinations required
hereunder (which accounting firm shall then be referred to as the Accounting
Firm hereunder). All fees and expenses of the Accounting Firm shall be borne
solely by the Company. The Consultant shall be responsible for payment of any
excise tax imposed under Section 4999 of the Code on any Parachute Payment as
described in this Section.
 
    9.  PROPRIETARY INFORMATION.  The Consultant agrees to comply fully with the
Company's policies relating to non-disclosure of the Company's trade secrets and
proprietary information and processes, as set out in the Confidentiality
Agreement set out as EXHIBIT A hereto (the "Confidentiality Agreement").

or indirect and whether by purchase, lease, merger, consolidation, liquidation
or otherwise) to all or substantially all of the Company's business and/or
assets shall assume this Agreement and agree expressly to perform this Agreement
in the same manner and to the same extent as the Company would be required to
perform it in the absence of a succession. For all purposes under this
Agreement, the term "Company" shall include any successor to the Company's
business and/or assets which executes and delivers the assumption agreement
described in this subsection (a) or which becomes bound by this Agreement or by
operation of law.

directly or indirectly, solicit, encourage or take any other action which is
intended to induce or encourage, or has the effect of inducing or encouraging
any employee or consultant of the Company to terminate his or her employment

        (c) The covenants contained in paragraphs (a) and (b) shall be construed
as a series of separate covenants, one for each country, province, state, city
or other political subdivision of the Restricted Territory. Except for
geographic coverage, each such separate covenant shall be deemed identical in
terms to the covenants contained in paragraphs (a) and (b). If, in any judicial
proceeding, a court of competent jurisdiction refuses to enforce any of such
separate covenants (or any part thereof), then such unenforceable covenant (or
such part) shall be eliminated from this Agreement to the extent necessary to
permit the remaining separate covenants (or portions thereof) to be enforced. In
the event that the provisions of this section are deemed to exceed the time,
geographic or scope limitations permitted by applicable law, then such
provisions shall be reformed to the maximum time, geographic or scope

InterQual, Inc.
293 Boston Post Road West
Marlborough, MA 01752-4615
 
Ladies and Gentlemen:
 
    We have acted as counsel to Access Health, Inc., a Delaware corporation
("Parent"), in connection with the merger (the "Merger") of Access Acquisition
Corp. 98A, a Delaware corporation ("Merger Sub") and a wholly owned subsidiary
of Parent, with and into InterQual, Inc., a Delaware corporation (the
"Company"), pursuant to the Amended and Restated Agreement and Plan of
Reorganization among Parent, Merger Sub and the Company dated as of June 4, 1998
(the "Merger Agreement"). This opinion is furnished to you pursuant to Section
6.2(d) of the Merger Agreement. Unless otherwise defined herein, the capitalized
terms used in this opinion have the meaning given to them in the Merger
Agreement.
 
    We have acted as counsel for Parent and Merger Sub in connection with the
negotiation of the Merger Agreement and the Registration Rights Agreement dated
as of the Closing Date (the "Registration Rights Agreement") (the Merger
Agreement and the Registration Rights Agreement are collectively referred to
herein as the "Agreements") and the effectuation of the Merger. As such counsel,
we have made such legal and factual examinations and inquiries as we have deemed
advisable or necessary for the purposes of rendering this opinion. In addition,
we have examined originals or copies of documents, corporate records and other
writings which we consider relevant for the purposes of this opinion. In such
examination, we have assumed the genuineness of all signatures on original
documents, the conformity to original documents of all copies submitted to us
and the due execution and delivery of all documents by any party other than
Parent and Merger Sub where due execution and delivery are a prerequisite to the
effectiveness thereof.
 
    As used in this opinion, the expression "to our knowledge" or "known to us"
with reference to matters of fact means that, after an examination of documents
made available to us by Parent and Merger Sub, and after inquiries of officers
of Parent and Merger Sub, but without any further independent factual
investigation, we find no reason to believe that the opinions expressed herein
are factually incorrect. Further, the expression "to our knowledge" with
reference to matters of fact refers to the current actual knowledge of the
attorneys of this firm who have worked on matters for Parent and Merger Sub
solely in connection with the Agreements and the transactions contemplated
thereby. Except to the extent expressly set forth herein or as we otherwise
believe to be necessary to our opinion, we have not undertaken any independent
investigation to determine the existence or absence of any fact, and no
inference as to our knowledge of the existence or absence of any fact should be
drawn from our representation of Parent and Merger Sub or the rendering of the
opinion set forth below.
 
    For purposes of this opinion, we are assuming that you have all requisite
power and authority, and have taken any and all necessary corporate action, to
execute and deliver the Merger Agreement and we assume that the representations
and warranties made by you in the Merger Agreement and pursuant thereto are true
and correct.
 
                                     A-D-1
<PAGE>
    The opinions hereinafter expressed are subject to the following
qualifications:
 
        A. We express no opinion as to the effect of rules of law governing
    specific performance, injunctive relief or other equitable remedies
    (regardless of whether any such remedy is considered in a proceeding at law
    or in equity);
 
        B.  We express no opinion as to the effect of applicable bankruptcy,
    insolvency, reorganization, moratorium and other similar federal or state
    laws affecting the rights of creditors generally;
 
        C.  We express no opinion as to compliance or non-compliance with the
    anti-fraud provisions of state and federal laws, rules and regulations
    concerning the issuance of securities;
 
        D. We express no opinion as to the enforceability of any of the
    agreements attached as exhibits to the Merger Agreement other than the
    Registration Rights Agreement (subject to the qualifications set forth
    herein);
 
        E.  We are members of the Bar of the State of California and we are not
    expressing any opinion as to any matter relating to laws of any jurisdiction
    other than the laws of the United States of America and the laws of the
    States of California and Delaware.
 
    Based upon and subject to the foregoing, and as except as set forth in the
Merger Agreement, we are of the opinion that:
 
        1.  Parent and Merger Sub have all requisite corporate power and
    authority to enter into the Agreements and to consummate the transactions
    contemplated thereby. The vote required of Parent's stockholders under the
    rules of the Nasdaq National Market to duly approve the Merger and the
    Merger Agreement is that number of shares as would constitute a majority of
    the total votes cast on the proposal to approve the Merger in person or by
    proxy at a special meeting of Parent's stockholders duly held under Delaware
    Law. The execution and delivery of the Agreements and the consummation of
    the transactions contemplated thereby have been duly authorized by all
    necessary corporate action on the part of Parent and Merger Sub. The Board
    of Directors and stockholders of each of Parent and Merger Sub have approved
    the Merger, the Merger Agreement and the Registration Rights Agreement. The
    Agreements have been duly executed and delivered by Parent and Merger Sub
    and constitute the valid and binding obligations of Parent and Merger Sub,
    enforceable against Parent and Merger Sub in accordance with their terms.
 
        2.  The issuance of the shares (the "Shares") of Parent Common Stock to
    be issued and delivered to the stockholders of Company in exchange for
    shares of Company Common Stock, will, when issued in accordance with the
    terms of the Merger Agreement, be validly issued, fully paid and
    nonassessable and free of liens, encumbrances or preemptive or similar
    rights contained in the Certificate of Incorporation or Bylaws of Parent;
    provided, however, that the Shares may be subject to restriction on transfer
    under state and/or federal securities laws.
 
        4.  To our knowledge, immediately prior to the Effective Time of the
    Merger, the authorized stock of Parent consisted of 75,000,000 shares of
    Common Stock, of which       shares were issued and outstanding as of
               , 1998, and 5,000,000 shares of Preferred Stock, none of which is
    issued or outstanding. To our knowledge, immediately prior to the Effective
    Time of the Merger, the authorized capital stock of the Merger Sub consisted
    of 1,000 shares of Common Stock, all of which was issued and outstanding and
    held by Parent. All such shares have been duly authorized, and all such
    issued and outstanding shares have been validly issued, fully paid and
    nonassessable and were not subject to preemptive rights created by statute
    or the Certificate of Incorporation or Bylaws of Parent.
 
        3.  Each of Parent and Merger Sub has all requisite corporate power and
    authority to enter into the Agreements, to perform its obligations
    thereunder and to consummate the transactions contemplated thereby. The
    execution and delivery of the Agreements, the performance by Parent and
    Merger Sub of their obligations thereunder and the consummation of the
    transactions contemplated thereby
 
                                     A-D-2
<PAGE>
    have been duly and validly authorized by all necessary corporate action on
    the part of Parent and Merger Sub, and have been approved by the Board of
    Directors of Parent and Merger Sub and the sole stockholder of Merger Sub.
    No other corporate proceeding on the part of Parent or Merger Sub is
    necessary to authorize the Agreements by Parent and Merger Sub or the
    performance of Parent's and Merger Sub's obligations thereunder or the
    consummation of the transactions contemplated thereby. The Agreements have
    been duly executed and delivered by Parent and Merger Sub and, assuming due
    execution and delivery by the Company, constitutes the legal, valid and
    binding obligations of Parent and Merger Sub, enforceable against Parent and
    Merger Sub in accordance with their terms.
 
        4.  To our knowledge, there is no action, suit, or proceeding pending or
    threatened against Parent or Merger Sub which challenges or seeks to
    prevent, enjoin, alter or materially delay any of the transactions
    contemplated by the Merger Agreement.
 
    This opinion is solely for your benefit and is not to be made available to
or relied upon by any other person without our express prior written consent.

                        FORM OF OPINION OF ROPES & GRAY
 
                                                                          , 1998
 
Access Health, Inc.

Broomfield, CO 80024
 
Ladies and Gentlemen:
 
    This opinion is furnished to you pursuant to Section 6.3(d) of the Amended
and Restated Agreement and Plan of Reorganization dated as of June 4, 1998 (the
"Agreement") by and among Access Health, Inc., a Delaware corporation (the
"Buyer"), Access Acquisition Corp. 98A, a Delaware corporation and a wholly
owned subsidiary of the Buyer ("Merger Sub") and InterQual, Inc., a Delaware
corporation (the "Company"). Capitalized terms used but not defined herein have
the respective meanings given to them in the Agreement.
 
    We have represented the Company in the negotiation, execution and delivery
of the Agreement and in such capacity we are familiar with the proceedings taken
by the Company in connection therewith.
 
    In rendering the opinions expressed below, we have examined and relied upon
such applicable charter documents, by-laws, and corporate resolutions and such
other documents, instruments, certificates and corporate records as we
considered necessary for purposes of this opinion. In addition, we have relied
as to matters of fact upon the representations and warranties in the Agreement
and representations made in certificates of officers of the Company delivered at
the Closing. Any statements in the opinion qualified by the words "to our
knowledge" or any words of similar effect indicate that the statements are made
based on the actual knowledge of the lawyers of this firm who have devoted
substantive attention to the transactions contemplated by the Agreement.
 
    We have also made such examination of law as we have deemed necessary for
purposes of this opinion. In all such examinations we have assumed the
genuineness of signatures, the authenticity of all documents submitted to us as
originals and the conformity to originals of all documents submitted to us as
copies.
 
    We are members of the Bar of Massachusetts and do not purport to be experts
in, or generally familiar with, or qualified to give legal opinions based upon,
the laws of any jurisdiction other than the General Corporation Law of the State
of Delaware and the federal laws of the United States of America.
 
    Based upon and subject to the foregoing, we are of the opinion that:
 
        1.  The Company is duly organized, validly existing and in good standing
    under the laws of the State of Delaware and is duly qualified to do business
    as a foreign corporation and is in good standing in each state in the United
    States from which it derived more than 10% of its annual revenues in 1997.
    The Company has the requisite power and authority to own or lease its
    property and assets and to conduct its business as it is currently being
    conducted.
 
        2.  Immediately prior to the Effective Time of the Merger: (a) the
    authorized capital stock of the Company consisted of: 100,000 shares of
    authorized Class A Common Stock, of which 10,000 shares were issued and
    outstanding; 100,000 shares of authorized Class B Common Stock, of which
    1,922 shares were issued and outstanding; and (b) all of such issued and
    outstanding shares had been duly authorized, validly issued, fully paid and
    non-assessable and were not subject to preemptive rights
 
                                     A-E-1
<PAGE>
    created by statute, the certificate of incorporation or bylaws of the
    Company or any agreement to which the Company is a party or by which it is
    bound.
 
        3.  The Company has all requisite corporate power and authority to enter
    into the Agreement, to perform its obligations thereunder and to consummate
    the transactions contemplated thereby. The execution and delivery of the
    Agreement, the performance of the Company of its obligations thereunder and
    the consummation of the transactions contemplated thereby have been duly and
    validly authorized by all necessary corporate action on the part of the
    Company and have been approved by the Board of Directors and the
    stockholders of the Company. No other corporate proceeding on the part of
    the Company is necessary to authorize the execution and delivery of the
    Agreement by the Company or the performance of the Company's obligations
    thereunder or the consummation of the transactions contemplated thereby. The
    Agreement has been duly and validly authorized, executed and delivered by
    the Company and constitutes a valid and binding agreement of the Company
    enforceable against the Company in accordance with its terms, except as
    enforcement may be limited by applicable bankruptcy, insolvency,
    reorganization, fraudulent transfer, moratorium or other similar laws
    affecting creditors' rights, and subject to general equity principles and to
    limitations on availability of equitable relief, including specific
    performance.
 
        4.  To our knowledge, except as described in the Company Disclosure
    Schedules delivered pursuant to the Agreement or as provided for in the
    Company's Certificate of Incorporation immediately prior to the Effective
    Time of the Merger: (a) there were no options, warrants, calls, rights,
    commitments or agreements of any character, written or oral, to which the
    Company is a party or by which it is bound obligating the Company to issue,
    delivery, sell, repurchase or redeem, or cause to be issued, delivered,
    sold, repurchased or redeemed, any shares of the capital stock of the
    Company; and (b) there were no options, warrants, calls, rights, commitments
    or agreements of any character, written or oral, to which the Company is a
    party or by which it is bound obligating the Company to grant, extend,
    accelerate the vesting of, change the price of, otherwise amend or enter
    into any such option, warrant, call, right, commitment or agreement.
 
        5.  To our knowledge, except as set forth on Schedule 2.3 of the Company
    Disclosure Schedules delivered pursuant to the Agreement, the Company does
    not have and since 1990 has never had any subsidiaries or companies
    controlled by the Company and does not otherwise own and since 1990 has
    never otherwise owned any shares of capital stock or any interest in, or
    controlled, directly or indirectly, any other corporation, partnership,
    association, joint venture or other business entity.
 
        6.  To our knowledge, except as set forth on the Company's Disclosure
    Schedules, there is no action, suit, investigation or proceeding pending or
    threatened against the Company or the Company's properties or assets before
    any court, arbitrator or administrative or governmental authority or agency
    which (i) challenges or seeks to prohibit, restrain or enjoin the
    transactions contemplated by the Agreement or places in question the
    validity or enforceability of the Agreement or (ii) could reasonably be
    expected to have a material adverse effect upon the business, operations,
    properties or condition (financial or otherwise) of the Company.
 
        7.  No consent, approval, authorization or order of any state or federal
    governmental agency or body not obtained by or in effect on the Closing Date
    is required for the execution and delivery by the Company of the Agreement,
    or for the consummation by the Company of the transactions contemplated
    thereby.
 
        8.  The execution and delivery by the Company of the Agreement does not,
    and the performance by the Company of the transactions contemplated thereby
    will not (i) violate the terms of, or conflict with, the Certificate of
    Incorporation, by-laws and other governing documents of the Company, as
    currently in effect, (ii) violate any provision of any constitution,
    statute, regulation, rule, injunction, judgment, order, decree, ruling,
    charge, or other restriction of any government, governmental agency, or
    court applicable to the Company, or (iii) to our knowledge and except as set
    forth in
 
                                     A-E-2
<PAGE>
    the Disclosure Schedules, conflict with, result in the breach of, constitute
    a default (with or without notice of lapse of time, or both) under, result
    in the acceleration of, create in any party the right to accelerate,
    terminate, modify, or cancel, or require any notice under any material
    agreement, contract, lease, license, instrument, or other arrangement to
    which the Company is a party or by which it is bound or to which any of its
    material assets are subject (or result in the imposition of any security
    interest, lien or encumbrance upon any of its properties or assets).
 
    Our opinion in paragraph 7 above that the Agreement is enforceable against
the Company in accordance with its terms is subject to (i) bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer and other laws of
general application affecting the rights and remedies of creditors and secured
parties and (ii) general principles of equity regardless of whether applied in a
proceeding in equity or at law.
 
    The foregoing opinions are solely for the benefit of you and your counsel
and may not be relied upon by any other person.
 
                                          Very truly yours,
 
                                          Ropes & Gray

           [LETTERHEAD]

PERSONAL & CONFIDENTIAL
 
Board of Directors
Access Health, Inc.

Broomfield, CO 80021
 
Members of the Board:
 
    You have asked our opinion with respect to the fairness to Access Health,
Inc. ("Access"), from a financial point of view and as of the date hereof, of
the Exchange Ratio provided in the Agreement and Plan of Reorganization dated
February 13, 1998 (including anticipated changes in the terms to be reflected in
a subsequent amendment, the "Agreement") among Access, Access Acquisition Corp.
98A and InterQual, Inc. ("InterQual"). Under the terms of the Agreement, Access
Acquisition Corp. 98A and InterQual will merge and the combined entity will
become a wholly-owned subsidiary of Access (the "Transaction") and the holders
of the InterQual Class A Shares will receive 360.42 shares, subject to certain
adjustments more fully described in the Agreement (the "Exchange Ratio"), of
common stock of Access ("Access Common Stock") in exchange for each InterQual
Class A Share and holders of InterQual Class B Shares will receive the product
of 0.99 and the Exchange Ratio (approximately 356.82) shares of Access Common
Stock in exchange for each InterQual Class B Share. The Exchange Ratio is
subject to the following adjustments: in general, if the average of the closing
prices of Access Common Stock during the twenty days ending the third day before
the Merger ("Access Common Stock Price") is less than 30.304, then the number of
shares of Access Common Stock issuable will be increased by a number which is
the lesser of 250,000 shares or 50% of the difference between (i) the amount of
shares that would result in the value of the consideration equaling $130 million
(based on the Access Common Stock Price) minus (ii) 4,290,000 shares.
 
    The Agreement states that the parties intend, and we have assumed, that the
Transaction will qualify as a tax-free reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, and be
accounted for as a "pooling of interests" under United States generally accepted
accounting principles ("GAAP"). The terms and conditions of the Transaction are
set out more fully in the Agreement.
 
    For purposes of this opinion we have (i) reviewed certain financial
information furnished to us by Access, including certain internal financial
analyses and forecasts prepared by the respective managements of Access and
InterQual; (ii) reviewed certain publicly available information concerning
Access; (iii) held discussions with the managements of each of Access and
InterQual concerning the businesses, past and current business operations,
financial condition and results of operations and the future prospects of each
company, independently and combined; (iv) reviewed the Agreement; (v) reviewed
the stock price and trading history of Access Common Stock; (vi) reviewed the
contribution by each company to pro forma combined revenue, operating income and
net income of the proposed combined company; (vii) reviewed the valuations of
publicly traded companies that we deemed comparable to InterQual; (viii)
compared the financial terms of the Transaction set forth in the Agreement with
other transactions that we deemed
 
                                  [LETTERHEAD]
 
                                      B-1
<PAGE>
relevant; (ix) analyzed the pro forma earnings per share of the combined
company; and (x) made such other studies and inquiries, and reviewed such other
data, as we deemed relevant.
 
    In connection with rendering our opinion, we have assumed and relied upon,
without independent verification, the accuracy and completeness of all
information reviewed by us in connection with our engagement by Access with
respect to the Transaction and have relied upon the assurances of management of
each of Access and InterQual that they are not aware of any facts that would
make such information inaccurate or misleading. Furthermore, we did not obtain
any independent evaluation or appraisal of any of the properties, assets or
liabilities (contingent or otherwise) of Access or InterQual, nor were we
furnished with any such evaluation or appraisal. With respect to the financial
forecasts and projections (and the assumptions and bases therefor) of each of
Access and InterQual which we have reviewed, upon the advice of Access, we have
assumed that such forecasts and projections have been reasonably prepared in
good faith on the basis of reasonable assumptions and reflect the best currently
available estimates and judgments of the managements of Access and InterQual,
respectively, as to the future financial performance of each of Access and
InterQual, respectively, and we have further assumed that such forecasts and
projections will be realized in the amounts and in the time periods currently
estimated by the respective managements of each of Access and InterQual.
Further, we have assumed that the historical financial statements of each of
Access and InterQual reviewed by us have been prepared and fairly presented in
accordance with GAAP. We have assumed that the Transaction will be consummated
upon the terms set forth in the Agreement without material alteration thereof
and that the Transaction will qualify for the tax and accounting treatment
described above. We have relied as to all legal matters relevant to rendering
our opinion on the advice of counsel.
 
    While we believe that our review, as described herein, is an adequate basis
for the opinion that we express, this opinion is necessarily based upon the
market, economic and other conditions as in effect on, and the information made
available to us as of, the date hereof. You should understand that subsequent
developments may affect the conclusion expressed in this opinion and that we
disclaim any undertaking or obligation to advise you or any person of any change
in any fact or matter affecting this opinion which may come or be brought to our
attention after the date of this opinion.
 
    We have provided certain investment banking services to Access from time to
time. In addition, we maintain a market in shares of Access Common Stock and
may, from time to time, trade in the securities of Access for our own account
and for the accounts of our customers and, accordingly, may at any time hold a
long or a short position in such securities. We are acting as financial advisor
to Access in connection with the Transaction and may provide financial advisory
and financing services to Access with respect to other transactions in the
future. We will receive fees in connection with the rendering of this opinion
and rendering advisory services in connection with the Transaction, and Access
has agreed to indemnify us for certain liabilities that may arise out of the
rendering of this opinion or such services.
 
   
    Our opinion is rendered at the request of and for the use of the Board of
Directors of Access. Our opinion is not intended to be and does not constitute a
recommendation to any shareholder of Access as to how such shareholder should
vote on the Transaction. Our opinion is limited to the fairness, from a
financial point of view and as of the date hereof, of the Exchange Ratio to
Access. We do not express any opinion regarding the current or future value of
the shares of Access Common Stock to be issued pursuant to the Transaction, nor
do we express any opinion regarding the fairness of the Transaction to InterQual
or to holders of InterQual Common Stock. Our opinion may be included in a proxy
or registration statement of Access distributed in connection with the
Transaction, provided that this opinion is reproduced therein in full and any
description of, or reference to, this opinion therein is in a form and substance
acceptable to us. Except as provided in the previous sentence, this opinion
shall not be reproduced, summarized, described or referred to, or furnished to
any party, without our prior written consent.
    
 
    Based upon and subject to the foregoing considerations, it is our opinion,
as investment bankers, that, as of the date hereof, the Exchange Ratio is fair
to Access from a financial point of view.
 
                                         Very truly yours,
 
                                         BANCAMERICA ROBERTSON STEPHENS

May 29, 1998
 
Board of Directors
InterQual, Inc.
293 Boston Post Road West
Marlborough, MA 01752-4615
 
Dear Sirs and Madams,
 
    You have requested our opinion (the "Opinion") as to the fairness, from a
financial point of view, to InterQual, Inc. ("InterQual" or the "Company") of
the consideration to be paid (the "Consideration") in the proposed merger (the
"Merger") with a subsidiary of Access Health, Inc. ("Access Health") pursuant to
an Agreement and Plan of Reorganization dated February 13, 1998 by and among
Access Health, Access Acquisition Corp. 98A and InterQual (including anticipated
changes in the terms to be reflected in a subsequent amendment, the
"Agreement"). The Agreement provides, among other things, that each outstanding
share of InterQual Class A common stock will be converted into the right to
receive 360.420 shares, subject to adjustment (the "Exchange Ratio"), of Access
Health common stock, and each outstanding share of InterQual Class B common
stock will be converted into the right to receive the product of 0.99 and the
Exchange Ratio (approximately 356.816) shares of Access Health common stock. The
Exchange Ratio is subject to the following adjustments: in general, if the
average of the closing prices of Access Health Common Stock during the twenty
days ending the third day before the Merger ("Access Health Stock Value") is
less than $30.304, then the number of shares of Access Health common stock
issuable will be increased by a number which is the lesser of (A) 250,000 shares
or (B) fifty percent (50%) of the amount of shares that would result from (i)
the quotient of $130,000,000 and the Access Health Stock Value, less (ii)
4,290,000 shares.
 
    It is our understanding that Access Health intends to account for the Merger
as a pooling of interests for financial reporting purposes and as a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended.
 
    Volpe Brown Whelan & Company, LLC ("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
Access Health 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.
VBW&Co. has been retained by InterQual to act as its financial advisor in
negotiations with Access Health and, upon conclusion of successful negotiations
with Access Health, to opine as to the fairness, from a financial point of view,
of the Consideration. VBW&Co. will receive a fee of $250,000 for rendering its
Opinion, no portion of which is conditioned upon the Opinion being favorable.
The $250,000 fee will be credited against an additional fee to be paid to
VBW&Co. upon the closing of the Merger.

    For the purposes of formulating the Opinion, we have, among other things:
 
        (i) reviewed the Agreement and Plan of Reorganization dated as of
    February 13, 1998 by and among Access Health, Access Acquisition Corp. 98A
    and InterQual, including anticipated changes in the terms to be reflected in
    a subsequent amendment;
 
        (ii) reviewed the affiliate/voting agreement dated February 13, 1998 by
    and among Access Health, InterQual and a stockholder of InterQual who may be
    determined to be an affiliate;
 
       (iii) reviewed the form of registration rights agreement to be completed
    at closing between Access Health and the stockholders of InterQual;
 
        (iv) reviewed the form of employment agreements between Access Health
    and certain InterQual employees;
 
        (v) reviewed the form of separation and consulting agreements between
    Access Health and Charles M. Jacobs and Access Health and Randolph W. Seed,
    M.D.;
 
        (vi) interviewed management of InterQual and Access Health concerning
    the business prospects, financial outlook and operating plans of each
    company individually and combined;
 
       (vii) reviewed certain historical and projected InterQual and Access
    Health financial statements and other relevant financial and operating data
    of InterQual and Access Health prepared by the respective management teams;
 
      (viii) considered the potential valuation which public market investors
    might accord InterQual in the context of an initial public offering of its
    securities;
 
        (ix) reviewed the valuation of selected publicly-traded companies we
    deemed comparable and relevant to InterQual;
 
        (x) reviewed, to the extent publicly-available, the financial terms of
    selected merger and acquisition transactions that we deemed comparable and
    relevant to the Merger;
 
        (xi) reviewed the relevant contribution each of InterQual and Access
    Health is making to the combined company in terms of financial results and
    compared the results of this analysis with the pro forma ownership of the
    combined company;
 
       (xii) performed a discounted cash flow analysis of InterQual as a
    stand-alone entity based upon the financial projections of InterQual
    management;
 
      (xiii) performed a pro forma financial impact analysis of the combined
    entity, based upon financial projections provided by InterQual and financial
    projections provided by Access Health and reviewed by InterQual; and
 
       (xiv) performed other such studies, analyses and inquiries and considered
    other such information as we deemed relevant.
 
    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 InterQual and Access Health and has
relied upon the assurances of InterQual and Access Health 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
any of them that would make any of the information made available to VBW&Co.
either incomplete or misleading. InterQual 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.
 
    With respect to the projected financial data of InterQual and Access Health
all of which has been provided by the management of InterQual or Access Health,
as well as the combined business plan,
 
                                      C-2
<PAGE>
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 InterQual and Access Health management 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 InterQual and
Access Health 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 InterQual and
Access Health 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.
 
    VBW&Co. has, furthermore, not made any independent appraisals or valuations
of any assets of InterQual or Access Health 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 InterQual or Access
Health with respect to their intellectual property and status of any litigation
pending or threatened against any 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 and
does not address the relative value ascribed, pursuant to the terms of the
Agreement, as between the shares of InterQual Class A common stock and the
shares of InterQual Class B common stock, relative merits of the Merger and any
alternatives to the Merger, InterQual's 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 analyses 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
InterQual's or Access Health'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 Access Health issued prior to or in
conjunction with the Merger. Furthermore, the Opinion does not constitute a
recommendation on 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 InterQual and is rendered to the Board of Directors in connection
with its consideration of the Merger.

    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 InterQual.
 
Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW
                                APPRAISAL RIGHTS
 
    262    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 Section 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 Section 251 (other than a merger effected pursuant to
Section 251(g) of this title), Section 252, Section 254, Section 257, Section
258, Section 263 or Section 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 a merger or
    consolidation, were either (i) listed on a national securities exchange or
    designated as a national market systems 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 Section 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 Section
    Section 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-1
<PAGE>
           d.   Any combination of the shares of stock, depository receipts 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 Section 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 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 for 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
    consented 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 Section 228
    or Section 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 is 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 20 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 a second notice
 
                                      D-2
<PAGE>
    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 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
 
                                      D-3
<PAGE>
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.
 
    (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 stockholders 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.
 
    (l) 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. (Last amended by Ch. 120, L.
'97, eff. 7-1-97.)

                             ---------------------
 
   
    This Prospectus relates to the public offering, which is not being
underwritten, from time to time by certain stockholders of the Company or by
pledgees, donees, transferees or other successors in interest that receive such
shares as a gift, partnership distribution or other non-sale related transfer
(the "Selling Stockholders") of up to 1,000,000 shares of Common Stock, par
value $0.001 per share (the "Shares"), of Access Health, Inc. ("Access Health"
or the "Company"), held by certain Selling Stockholders. See "Selling
Stockholders." The Company will receive no part of the proceeds of such sales.
All of the shares were originally issued by the Company to the Selling
Stockholders as consideration for the acquisition of InterQual, Inc. on June 30,
1998. The Shares are being registered by the Company pursuant to registration
rights granted to the Selling Stockholders.
    
 
    The Selling Stockholders have not advised the Company of any specific plans
for the distribution of the Shares covered by this Prospectus. It is
anticipated, however, that the Shares may be offered by the Selling Stockholders
from time to time in one or more transactions on the Nasdaq National Market, in
privately negotiated transactions at such prices as may be agreed upon, or in a
combination of such methods of sale. The Selling Stockholders may effect such
transactions by selling the Shares to or through broker-dealers and such
broker-dealers may receive compensation in the form of discounts, concessions or
commissions from the Selling Stockholders or the purchasers of the Shares for
whom such broker-dealers may act as agent or to whom they sell as principal or
both (which compensation to a particular broker-dealer might be in excess of
customary commissions). See "Plan of Distribution." The price at which any of
the Shares may be sold, and the commissions, if any, paid in connection with any
such sale, are unknown and may vary from transaction to transaction. The Company
will pay all expenses incident to the offering and sale of the Shares to the
public other than any commissions and discounts of underwriters, dealers or
agents and any transfer taxes. See "Plan of Distribution."
 
   
    The Company's Common Stock is listed on the Nasdaq National Market under the
symbol "ACCS." On June 8, 1998 the last sale price of the Company's Common Stock
was $25.3125 per share.
    
 
    THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. SEE "RISK FACTORS" ON PAGE 2
FOR INFORMATION THAT SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.
 
    The Securities and Exchange Commission (the "Commission") may take the view
that, under certain circumstances, the Selling Stockholders and any
broker-dealers or agents that participate with the Selling Stockholders in the
distribution of the Shares may be deemed to be "underwriters" within the meaning
of the Securities Act of 1933, as amended (the "Securities Act"). Commissions,
discounts or concessions received by any such broker-dealer or agent may be
deemed to be underwriting commissions under the Securities Act. The Company and
the Selling Stockholders have agreed to certain indemnification arrangements.
See "Plan of Distribution."

                                  THE COMPANY
 
    Access Health is a leading provider of care management products and services
to the health care industry. Access Health provides its services primarily
through four telephonic care centers, which are staffed by registered nurses and
other health care professionals. Access Health's clients include health
maintenance organizations ("HMOs"), preferred provider organizations ("PPOs"),
indemnity insurers, integrated delivery systems, government agencies,
self-insured employers and physician groups. Access Health's objective is to
measurably improve the delivery of health care through integrated programs that
help individuals effectively manage their health needs. Its products and
services are designed to help reform an inefficient health care system in ways
that benefit health care payors, providers and individuals.
 
    Access Health was founded in 1987 and until 1993 primarily provided consumer
health care information products and services designed to help hospitals and
other health care providers market their services. Beginning in 1993, Access
Health changed its focus to developing, marketing and delivering personal health
management products and services to health plans and payors, which were
primarily designed as a value added member benefit to help attract and retain
members. At the same time, Access Health altered its business model to price its
products and services predominantly on a recurring per-member per-month fee
basis rather than on a non-recurring basis. Access Health enjoyed significant
growth of its personal health management business through mid-1996, at which
point customer demand for care management products which provided demonstrable
cost savings began to intensify. At the time, health care service providers were
experiencing increased price competition and rising medical costs, resulting in
unprecedented high medical loss ratios and lower profitability. In November
1996, Access Health merged with Informed Access Systems, Inc. ("Informed
Access"), a developer of leading-edge clinical assessment tools and care
management programs. With this merger, Access Health significantly expanded its
suite of care management products. Also in November 1996, Access Health acquired
Clinical Reference Systems, Ltd. ("CRS"), which develops health information and
patient education software programs. Access Health's care management business
has grown dramatically; the number of enrolled members has increased to
approximately 25 million in February 1998 from over 14 million at the end of
fiscal 1996. In June 1998, Access Health acquired InterQual, Inc. which develops
and markets clinical decision support information which assist health care
payors and providers in making and evaluating level of care and clinical
appropriateness decisions.
 
    Access Health was incorporated in California in October 1987 as Referral
Systems Group, Inc., adopted the name Access Health Marketing, Inc. in July
1990, reincorporated in Delaware in January 1992 and changed its name to Access
Health, Inc. in March 1995. Access Health maintains its principal executive
offices at 335 Interlocken Drive, Broomfield, Colorado 80021, and its telephone
number is (303) 466-9500.
 
                                  RISK FACTORS
 
    UNCERTAINTY RELATED TO OBTAINING, EXPANDING AND RETAINING CONTRACTS MAY
IMPACT RESULTS OF OPERATIONS. The Company's ability to increase revenues and
profitability is largely dependent on the Company's ability to secure additional
care management contracts and to retain and expand existing contracts. The
Company could be adversely affected by the termination or non-renewal of any of
the Company's contracts, or by renegotiation of the terms of contracts,
particularly if the affected contracts cover a large number of members or
represent a significant portion of the Company's care management revenue. For
example, in fiscal 1997, the Company renegotiated various older care management
contracts, typically upon renewal, to bring price terms based on minimum
membership and utilization rates previously negotiated in line with actual
membership and utilization rates. Such rationalizations resulted in a decrease
of revenue by approximately $7.0 million in fiscal 1997. During the first half
of fiscal 1998 contract rationalizations decreased revenue by approximately $2.7
million and for the balance of the year the Company expects
 
                                       2
<PAGE>
                                   [ALTERNATE PAGES FOR PROSPECTUS]
 
contract rationalizations to reduce revenue under such contracts by
approximately $3.2 million. Any factors adversely affecting the market for the
care management product or the licensing and support services products,
including factors outside of the Company's control, such as adverse publicity or
government regulatory action, could have a material adverse effect on the
Company.
 
    DEPENDENCE ON PRINCIPAL CUSTOMERS.  Significant portions of the Company's
revenues are generated by a limited number of customers. The Company's care
management contracts range from approximately 800 members to 3.0 million members
per contract. In fiscal 1997, the five largest single care management
enrollments totaled 3.0 million, 2.4 million, 1.9 million, 1.5 million and 1.5
million members. In fiscal 1997, the Company's three largest customers accounted
for approximately 8.0%, 7.8%, and 6.9% of the Company's total revenues and the
Company's top five customers, in the aggregate, accounted for approximately
33.4% of the Company's total revenues. After an initial term of approximately
one to four years, contracts generally can be terminated upon 60 to 360 days
notice to the Company. Three of the Company's five largest contracts are up for
renewal in the second half of fiscal year 1998. The Company's contracts could be
subject to early termination by its customers if the Company were not in
compliance with any applicable government regulation. The termination,
non-renewal or renegotiation of any such agreements could have a material
adverse effect on the Company's operating results. See "Government Regulation."
 
    UNCERTAINTY OF FUTURE OPERATING RESULTS.  The Company's quarterly operating
results may fluctuate significantly in the future as a result of a variety of
factors, many of which are outside the Company's control. There can be no
assurance that the Company's revenues and profitability will increase during
fiscal 1998 and beyond. The Company's revenues may be materially adversely
affected by the termination or non-renewal of the Company's contracts or by the
renegotiation of the terms of such contracts. The Company may incur
significantly increased sales, marketing, and promotional expenses during fiscal
1998, and may devote additional resources to the further development of care
management, disease management or other new products. To the extent that the
Company incurs increased expenses, the Company's operating results will be
adversely affected unless revenues and operating margins increase sufficiently
to offset such expenditures. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    COMPETITION.  The market for the Company's products and services is highly
competitive. There are a number of competitors that offer products or services
that compete with some or all of those offered by the Company. Existing and
potential clients may also evaluate the Company's products or services against
internally developed programs. Increased competition could result in pricing
pressure and margin erosion. In its existing business and as the Company offers
new products or services, or enters new markets, it may face increased
competition from competitors, some of which may have substantially greater
financial, marketing and technical resources than the Company. In particular,
several small competitors have recently been acquired or are expected to be
acquired by companies with substantially greater financial, marketing and
technical resources than the Company, and this could lead to increased
competition. There can be no assurance that the Company will continue to compete
successfully.
 
    CHANGING HEALTH CARE MARKET AND NEW PRODUCT DEVELOPMENT.  The health care
industry has undergone significant changes in recent years, and changes are
expected to continue. Containing health care costs has become a national
priority. As a result, the health care industry has become increasingly
dominated by managed health care plans, causing cost containment pressure to
rise. To address these changes, the Company shifted its business focus in 1993
to payors from providers and developed its personal health management services.
There is no assurance that the Company's existing products and services will
achieve continued success or that its new products and services will succeed.
There also can be no assurance that continued industry change will not adversely
affect the Company's ability to compete.

                                   [ALTERNATE PAGES FOR PROSPECTUS]
 
Continued change may cause the Company to incur significant product development
and marketing expenses. The Company's future success will depend on the
Company's ability to adapt to the changing needs of the health care industry.
 
    CARE CENTER OPERATIONS.  The Company maintains member service and data
centers ("care centers") in Rancho Cordova, California; Chicago, Illinois;
Broomfield, Colorado; and Phoenix, Arizona. The Company's operations depend on
the adequate functioning of the computer and telephone systems in its call
centers. Although the Company has taken precautions to provide for power,
computer, and telephone systems redundancy, there can be no assurance that a
fire or other disaster affecting the centers or an equipment failure would not
disable the Company's systems for a significant period of time. Any significant
damage to the Company's facilities or an equipment failure could have a material
adverse effect on the Company's results of operations.
 
    The successful operation of the Company's care centers is based on a
networked information system. The information system provides care center nurses
and health care counselors with access to care management applications and a
database of information including member information, plan rules, physician
information and clinical algorithms and guidelines. The Company is in the
process of developing a new information system which combines certain aspects of
the different systems developed by Access Health and Informed Access. Failure to
successfully develop and implement this new information system could delay
revenues or increase operating costs and could have a material adverse effect on
the Company. The ability to continue to develop, implement and support the
Company's information systems is dependent on its ability to employ and retain
experienced technical personnel. If the Company is unable to hire and retain
required personnel or is required to pay compensation at significantly higher
levels to attract and retain technical personnel it could have a material
adverse effect on the Company's financial results.
 
    LIMITATIONS ON PROTECTION OF PROPRIETARY RIGHTS.  The Company regards its
software, clinical algorithms and nursing assessment tools, clinical operational
expertise and marketing and program operation materials as proprietary and takes
action to protect its intellectual property with patents, copyrights,
trademarks, trade secret laws and restrictions on disclosure, copying and
transferring title. Despite the Company's precautions, it may be possible for
unauthorized third parties to copy aspects of the Company's products or to
obtain and use information that the Company regards as proprietary. There can be
no assurance that competitors, some of which have substantial resources and have
made substantial investments in competing technologies, will not seek to apply
for and obtain patents that will prevent, limit or interfere with the Company's
ability to market its products and services either in the United States or in
international markets. The Company could incur substantial costs defending
itself in suits against the Company or its proprietary rights or in bringing
suits against those parties to enforce the Company's proprietary rights. The
Company has been issued patents on its clinical algorithms in the United States
and has filed for patent protection in some foreign countries. There is no
assurance that such patents will not be challenged or invalidated. Existing
copyright laws afford only limited practical protection. In addition, the laws
of some foreign countries do not protect the Company's proprietary rights to the
same extent as do the laws of the United States, which could be a factor
depending upon into which countries outside the United States the Company
expands.
 
    MANAGEMENT OF GROWTH.  The Company has experienced rapid growth in recent
years. Continued rapid growth may place a significant strain on the Company's
management, telecommunications systems, operational infrastructure, working
capital and financial and management control systems. The difficulties of
managing growth may be increased by the necessity of coordinating geographically
separated organizations. In order for the Company to manage its client base
successfully, management will be required to anticipate the changing demands of
their growing operations and to adopt systems and procedures accordingly.
Failure to effectively implement or maintain such systems and procedures could
adversely
 
                                       4
<PAGE>
                                   [ALTERNATE PAGES FOR PROSPECTUS]
 
affect the Company's business, results of operation and financial condition.
Further, there can be no assurance that the Company's current information
systems, telecommunications systems and operational infrastructure will be
adequate for its future needs, or that the Company will be successful in
implementing new systems. Failure to upgrade its information systems,
telecommunications systems and operational infrastructure or unexpected
difficulties encountered with these systems during expansion could adversely
affect the Company's business, financial condition and results of operations.
 
    ACQUISITION-RELATED RISKS.  The Company has grown in part through mergers
and acquisitions. The Company has entered into an agreement to acquire
InterQual, Inc. and intends to evaluate acquisitions of other product lines and
businesses as part of its business strategy. The process of integrating an
acquired company's business into the Company's operations may result in
unforeseen operating difficulties and expenditures and may absorb significant
management attention that would otherwise be available for the ongoing
development of the Company's business. Moreover, there can be no assurance that
the anticipated benefits of an acquisition will be realized. Future acquisitions
by the Company could result in potentially dilutive issuance of equity
securities, the incurrence of debt and contingent liabilities and amortization
expenses related to goodwill and other intangible assets, which could materially
adversely affect the Company's operating results and financial condition. In
addition, acquisitions involve numerous risks, including difficulties in
managing diverse geographic operations, the diversion of management's attention
from other business concerns, risks of entering markets in which the Company has
no or limited direct prior experience, the addition of unanticipated
administrative and other expense, and the potential loss of key employees of the
acquired company. The inability of the Company's management to respond to
changing business conditions effectively, including the changes associated with
its acquired businesses and product lines, could have a material adverse effect
on the Company's results of operations.
 
    KEY EMPLOYEES AND MANAGEMENT OF CHANGE.  The Company's success depends on a
limited number of key management employees, most of whom are subject to
post-employment non-competition restrictions. The loss of the services of one or
more of these employees could have a material adverse effect on the Company. The
Company believes that its continued success also will depend in large part on
its ability to attract and retain highly skilled management, nursing, technical,
marketing, and sales personnel. Competition for such personnel is intense, and
there can be no assurance that the Company will be successful in attracting and
retaining such personnel as necessary.
 
    Furthermore, the Company's ability to manage change and growth successfully
will require the Company to continue to improve its management expertise as well
as its financial systems and controls.
 
    VOLATILITY OF STOCK PRICE.  The market for the Company's stock is highly
volatile. The trading price of the Company's common stock is subject to wide
fluctuations in response to a variety of factors including the signing or loss
of a major contract, changes in market analyst estimates and recommendations for
the Company's common stock, fluctuations in operating results, the failure of
operating results to meet market analyst's estimates, changes in government
regulation and general conditions in the health care industry and the economy,
any of which could cause the price of the Company's common stock to fluctuate,
perhaps substantially. In addition, in recent years stock prices have
experienced significant fluctuations, which have particularly affected the
market price for the securities of health care companies and which often have
been unrelated to the operating performance of these companies.
 
    GOVERNMENT REGULATION.  The health care industry is subject to extensive and
evolving government regulation at both the Federal and state levels relating to
many aspects of the Company's and its clients' businesses in use of the
Company's programs, including the provision of health care services,
teleservicing, and health care referral programs. These statutes and regulations
in many cases predate the development of telephone-based health care information
and other interstate transmission and communication of medical information and
services. The literal language of certain of these statutes and regulations
 
                                       5
<PAGE>
                                   [ALTERNATE PAGES FOR PROSPECTUS]
 
governing the provision of health care services, including the practice of
nursing and the practice of medicine, could be construed by regulatory
authorities to apply to certain of the Company's activities, including without
limitation teleservicing activities which use California, Illinois, Arizona, and
Colorado registered nurses to provide out-of-state care management services such
as nursing assessments and information regarding appropriate sources of care and
treatment time frames. These statutes and regulations could also apply to
certain activities of the Company's health service customers when operating the
Company's programs. The Company understands that state regulators in some states
have informed some entities that they are adopting such a construction. The
Company has taken steps to comply with such regulatory interpretation, but there
can be no assurance that such steps will be sufficient to protect the Company
from the effects of any such regulatory action. In addition, the literal
language of the statutes and regulations governing health maintenance
organizations and other plans that provide or arrange for the provision of
health care services for a prepaid or periodic charge could be construed by
regulatory authorities to apply to certain activities of the Company that are
provided on a per-member, per-month basis. The Company has not been made, nor is
it aware that any other company providing out-of-state teleservicing has ever
been made, the subject of such requirements by a regulatory authority. However,
if regulators seek to enforce any of the foregoing statutory and regulatory
requirements, the Company, its employees and/or its clients could be required to
obtain additional licenses or registrations, to modify or curtail the operation
of the Company's programs, to modify the method of payment for the Company's
programs, or to pay fines or incur other penalties.
 
    The payment of remuneration to induce the referral of health care business
has been a subject of increasing governmental and regulatory focus in recent
years. Section 1128B(b) of the Social Security Act (sometimes referred to as the
"Federal anti-kickback statute") provides criminal penalties for individuals or
entities that knowingly and willfully offer, pay, solicit or receive
remuneration in order to induce referrals for items or services for which
payment may be made under the Medicare and Medicaid programs and certain other
government-funded programs. The Social Security Act provides authority to the
Office of the Inspector General through civil proceedings to exclude an
individual or entity from participation in the Medicare and state health
programs if it is determined any such party has violated Section 1128B(b) of the
Social Security Act. Regulations have been promulgated specifying certain
payment practices, which will not be subject to criminal prosecution or civil
exclusion. These regulations, commonly referred to as the "safe harbor"
regulations, do not expand the scope of the Federal anti-kickback statute, and
the fact that a business arrangement does not fit within a safe harbor does not
mean the business arrangement violates the Federal anti-kickback statute. The
Company's programs do not meet the requirements of the safe harbor for referral
services. A number of states in which the Company operates have anti-kickback
statutes similar to the Federal statute as well as statutory and regulatory
requirements governing referral agencies and regulating franchising and business
opportunity ventures. In addition, the Federal government and a number of states
have enacted statutes which contain outright prohibitions on referrals for
specified services which are made by referring providers who have an ownership
interest in, or compensation arrangement with, the entity to which the referral
is made. If the Company or the use of its products and services were to be found
in violation of such statutes, the Company or its clients could be required to
modify or curtail the operation of the Company's programs, or to pay fines or
incur other penalties, and the Company's clients could be excluded from
participation in the Medicare and Medicaid programs and could be precluded from
charging fees and obtaining reimbursement for specified services.
 
    There can be no assurance that the Company or the use of its products and
services will not be subject to review or challenge by government regulators
under any of the foregoing statutes and regulations that apply to health care
services and products. In addition, additional laws and regulations could be
enacted in the future that would regulate the Company or the use of its products
and services. Any government investigative or enforcement actions with respect
to the Company or the use of its products or services
 
                                       6
<PAGE>
                                   [ALTERNATE PAGES FOR PROSPECTUS]
 
could generate adverse publicity irrespective of the final outcome, and could
have a material adverse effect on the Company.
 
    RISK MANAGEMENT.  In recent years, participants in the health care industry,
including physicians, nurses and other health care professionals, have been
subject to an increasing number of lawsuits alleging malpractice, product
liability and related legal theories, many of which involve large claims and
significant defense costs. Due to the nature of its business, the Company could
become involved in litigation regarding the telephone information given by its
registered nurses or those of its licensees with the risk of adverse publicity,
significant defense costs and substantial damage awards. The Company has
established policies and procedures that limit the information provided by its
registered nurses to that contained in its clinical algorithms and protocols and
in other approved reference sources. In connection with its teleservices
operations, the Company has a quality assurance program that includes real-time
audits of calls and post call reviews to monitor compliance with established
policies and procedures. Generally, clients review and approve the Company's
clinical algorithms, protocols and guidelines prior to program implementation
and do not modify them without medical approval. To date, the Company has not
been the subject of any claim involving either its clinical assessment systems,
the operation of its teleservicing centers or the operation by hospital or other
clients of on-site call centers. However, there can be no assurance that claims
will not be brought against the Company. Even if such claims ultimately prove to
be without merit, defending against them can be time consuming and expensive,
and any adverse publicity associated with such claims could have a material
adverse effect on the Company. Further, there can be no assurance that the
Company has appropriate or sufficient coverage under the existing insurance
plans or that they will be able to obtain appropriate or sufficient amounts of
insurance in the future to address the foregoing risks on terms that are
commercially reasonable.
 
    IMPACT OF THE YEAR 2000 ON COMPUTER SYSTEMS.  The architectural design on
the Company's computer systems and infrastructure have taken into account the
effect of integrating existing date data with date data from the Year 2000 and
beyond. As a result, the Company believes it will address and resolve any
possible issue associated with the integration of Year 2000 date data in a
timely fashion and will not materially affect future financial results or cause
reported financial information to be inaccurate.* Nevertheless, unforeseen
internal problems or unanticipated events including the inability of third party
vendors to integrate Year 2000 date data could occur causing a material adverse
effect on the Company's business, results of operations and financial condition.

(1) Beneficial ownership is determined in accordance with the rules of
    Securities and Exchange Commission. In computing the number of shares
    beneficially owned by a person and the percentage ownership of that person,
    shares of Common Stock subject to options or warrants held by that person
    that are currently exercisable or exercisable within 60 days of the date of
    this Prospectus are deemed outstanding. Such shares, however, are not deemed
    outstanding for the purposes of computing the percentage ownership of each
    other person. Except as indicated in the footnotes to this table and
    pursuant to applicable community property laws, each stockholder named in
    the table above has sole voting and investment power with respect to the
    shares set forth opposite such stockholder's name. Percentage beneficial
    ownership is based on 23,283,742 shares of Common Stock outstanding as of
    May 15, 1998 (after giving effect to the issuance of 4,290,000 shares of
    Common Stock as consideration for the acquisition of InterQual Inc. on June
    30, 1998).

    pursuant to a Pledge Agreement, effective on January 1, 1997, between
    Randolph Seed, M.D. and Charles M. Jacobs (the "Pledge Agreement"), and the
    amendment thereto, was pledged to Mr. Jacobs, together with the stock's
    voting and other rights, until such time as Mr. Jacobs' loan to Dr. Seed is
    repaid in full and (ii) 14,056 shares of Common Stock owned by a trust as to
    which Mr. Jacobs shares voting power.

                              PLAN OF DISTRIBUTION
 
    Access Health will not receive any of the proceeds from the sale by the
Selling Stockholders of the shares of Access Health Common Stock offered hereby.
Any or all of the shares of Access Health Common Stock may be sold from time to
time (i) to or through underwriters or dealers, (ii) directly to one or more
other purchasers, (iii) through agents on a best-efforts basis, or (iv) through
a combination of any such methods of sale.
 
    The shares of Access Health Common Stock offered hereby may be sold from
time to time by the Selling Stockholders, or by pledgees, donees, transferees or
other successors in interest. The shares offered by the Selling Stockholders may
be sold from time to time on one or more exchanges or in the over-the-counter
market, or otherwise at market prices prevailing at the time of sale, at prices
relating to such prevailing market prices or at negotiated prices. In addition,
the Selling Stockholders may sell their shares covered by this Prospectus
through customary brokerage channels, either through broker-dealers acting as
agents or brokers, or through broker-dealers acting as principals, who may then
resell the shares, or at private sale or otherwise, at market prices prevailing
at the time of sale, at prices related to such prevailing market prices or at
negotiated prices. The Selling Stockholders may effect such transactions by
selling shares to or through broker-dealers, and such broker-dealers may receive
compensation in the form of underwriting discounts, concessions, commissions, or
fees from the Selling Stockholders and/or purchasers of the shares for whom such
broker-dealers may act as agent or to whom they may sell as principal, or both
(which compensation to a particular broker-dealer might be in excess of
customary commissions). Without limiting the generality of the foregoing, the
shares may be sold by one or more of the following: (a) a block trade in which
the broker or dealer so engaged will attempt to sell the shares as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker or dealer as principal and resale by such
broker or dealer for its account pursuant to this Prospectus; (c) an exchange
distribution in accordance with the rules of such exchange; and (d) ordinary
brokerage transactions and transactions in which the broker solicits purchasers.
In effecting sales, brokers or dealers engaged by the Selling Stockholders may
arrange for other brokers or dealers to participate. Brokers or dealers will
receive commissions or discounts from Selling Stockholders in amounts to be
negotiated prior to the sale. In addition, any securities covered by this
Prospectus which qualify for sale pursuant to Rules 144 or 145 may be sold under
such rules rather than pursuant to this Prospectus.
 
    The Selling Stockholders and any such underwriters, dealers or agents that
participate in the distribution of the Access Health Common Stock may be deemed
to be underwriters within the meaning of the Securities Act, and any profit on
the sale of the Access Health Common Stock by them and any discounts,
commissions or concessions received by them may be deemed to be underwriting
discounts and commissions under the Securities Act. The Access Health Common
Stock may be sold from time to time in one or more transactions at a fixed
offering price, which may be changed, or at varying prices determined at the
time of sale or at negotiated prices. Such prices will be determined by the
Selling Stockholders or by an agreement between the Selling Stockholders and
underwriters or dealers. Brokers or dealers acting in connection with the sale
of Access Health Common Stock contemplated by this Prospectus may receive fees
or commissions in connection therewith.

with any distribution of the Access Health Common Stock, the Selling
Stockholders may not, directly or indirectly, bid for, purchase or attempt to

completed.
 
    In order to comply with certain states' securities laws, if applicable, the
Access Health Common Stock will be sold in such jurisdictions only through
registered or licensed brokers or dealers.
 
    Access Health has agreed to indemnify the Selling Stockholders and certain

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Registrant's Certificate of Incorporation and Bylaws include provisions
to (i) eliminate the personal liability of the Registrant's directors for
monetary damages resulting from breaches of their fiduciary duty to the extent
permitted by Section 102(b)(7) of the Delaware General Corporation Law (the
"DGCL") and (ii) require the Registrant to indemnify its directors and officers
to the fullest extent permitted by Section 145 of the DGCL, including
circumstances in which indemnification is otherwise discretionary. Pursuant to
Section 145 of the DGCL, a corporation generally has the power to indemnify its
present and former directors, officers, employees and agents against expenses
incurred by them in connection with any suit to which they are, or are
threatened to be made, a party by reason of their serving in such positions so
long as they acted in good faith and in a manner they reasonably believed to be
in, or not opposed to, the best interests of the corporation, and with respect
to any criminal action, they had no reasonable cause to believe their conduct
was unlawful. The Registrant believes that these provisions are necessary to
attract and retain qualified persons as directors and officers. These provisions
do not eliminate liability for breach of the director's duty of loyalty to the
Registrant and its stockholders, for acts or omissions not in good faith or
involving intentional misconduct or knowing violations of law, for any
transaction from which the director derived an improper personal benefit, or for
any willful or negligent payment of any unlawful dividend or any unlawful stock
purchase agreement or redemption.
 
    The Registrant has entered into agreements with its directors and executive
officers that require the Registrant to indemnify such persons against expenses,
judgments, fines, settlements and other amounts incurred (including expenses of
a derivative action) in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or an executive officer of the Registrant
or any of its affiliated enterprises, provided such person acted in good faith
and in a manner such person reasonably believed to be in or not opposed to the
best interests of the Registrant and, with respect to any criminal proceeding,
had no reasonable cause to believe this conduct was unlawful. The
indemnification agreements also set forth certain procedures that will apply in
the event of a claim for indemnification thereunder.
 
    The Merger Agreement provides that commencing with the effectiveness of the
Merger, Access Health shall or shall cause InterQual to provide indemnification,
to the same extent and under similar conditions and procedures as offered to
officers and director of Access Health, to each current officer or director of
InterQual (or any person who shall become an officer or director between the
date of the Merger Agreement and prior to the Effective Time) and each person
who served at the request of InterQual as an officer or director of another
entity. The indemnity obligations of Access Health will survive the consummation
of the Merger for a period of six years and any additional time period beyond
six years as necessary to resolve a claim for indemnification made during the
initial six year period. In the event Access Health merges with another entity
or transfers all or a substantial portion of its properties or assets to any
other person or entity, such successor or assignee must assume such
indemnification obligations of Access Health.

ITEM 22. UNDERTAKINGS
 
    (1) The undersigned registrant hereby undertakes:
 
        (a) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
 
            (i) To include any prospectus required by section 10(a)(3) of the
       Securities Act;
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with the SEC
       pursuant to Rule 424(b)
 
                                      II-4
<PAGE>
       (Section230.424(b) of this chapter) if, in the aggregate, the changes in
       volume and price represent no more than a 20% change in the maximum
       aggregate offering price set forth in the "Calculation of Registration
       Fee" table in the effective registration statement;
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.
 
        (b) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.
 
        (c) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    (2) The undersigned registrant hereby undertakes as follows: 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.
 
    (3) The registrant undertakes 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 Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to 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, 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.
 
    (4) The undersigned registrant hereby undertakes 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.

     RE:  REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-4, as amended by 
Amendment No. 1 thereto which will be filed by you with the Securities and 
Exchange Commission (the "Commission") on June 10, 1998 (as amended, the 
"Registration Statement") in connection with the registration under the 
Securities Act of 1933, as amended, of up to 4,540,000 shares of your Common 
Stock (the "Shares").  As your counsel in connection with this transaction, 
we have examined the proceedings taken and are familiar with the proceedings 
proposed to be taken by you in connection with the sales and issuance of the 
Shares.

     It is our opinion that upon conclusion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities law of 
the various states where required, the Shares, when issued and sold in the 
manner described in the Registration Statement, will be legally and validly 
issued, fully paid and non-assessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the proxy statement/prospectus and notice and
consent solicitation statement constituting a part thereof, and any amendment
thereto.

                              Very truly yours,

     RE:   MERGER AMONG ACCESS HEALTH, INC., ACCESS ACQUISITION CORP. 98A AND
           INTERQUAL, INC.


Ladies and Gentlemen:

     We have acted as counsel to Access Health, Inc., a Delaware corporation 
("Access") in connection with the proposed merger (the "Merger") of Access 
Acquisition Corp. 98A, a Delaware corporation and a wholly-owned subsidiary 
of Access ("Merger Sub"), with and into InterQual, Inc., a Delaware 
corporation ("InterQual") pursuant to an Agreement and Plan of Reorganization 
dated as of February 13, 1998, as amended (the "Reorganization Agreement"), 
among Access, Merger Sub and InterQual. The Merger and certain proposed 
transactions incident thereto are described in the Registration Statement on 
Form S-4 (the "Registration Statement") which contains a prospectus and joint 
proxy statement. This opinion is being rendered pursuant to the requirements 
of Item 21(a) of Form S-4 under the Securities Act of 1933, as amended. 
Unless otherwise indicated, any capitalized terms used herein and not 
otherwise defined have the meaning ascribed to them in the the Registration 
Statement.

     Based upon and subject to the foregoing, the discussion contained in the 
Registration Statement under the caption "Certain Federal Income Tax 
Considerations," subject to the limitations and qualifications described 
therein, constitutes our opinion as to the material federal income tax

Common Stock pursuant to the Merger.

     This opinion is furnished to you solely for use in connection with the 
Registration Statement. We hereby consent to the filing of this opinion as 
an exhibit to the Registration Statement. We also consent to the reference to 
our firm name wherever appearing in the Registration Statement with respect 
to the opinion and discussion of the material federal income tax consequences 
of the Merger, including the prospectus and joint proxy statement

consent, we do not thereby admit that we are in the category of persons whose 
consent is required under Section 7 of the Securities Act of 1933, as 
amended, or the rules and regulations of the Securities and Exchange 
Commission thereunder, nor do we thereby admit that we are experts with 
respect to any part of such Registration Statement within the meaning of the 
term "experts" as used in the Securities Act of 1933, as amended, or the 
rules and regulations of the Securities and Exchange Commission thereunder.

Ladies and Gentlemen:

     We have acted as counsel to InterQual, Inc. ("InterQual"), a Delaware 
corporation, in connection with the planned transaction (the "Merger") 
contemplated by the Amended and Restated Agreement and Plan of 
Reorganization, dated June 4, 1998, by and among Access Health, Inc., a 
Delaware corporation ("Access Health"), Access Acquisition Corp. 98A, a 
Delaware corporation and a wholly-owned subsidiary of Access Health, Inc. 
("Merger Sub"), and InterQual, Inc. (the "Reorganization Agreement").  In 
connection with the Merger, Merger Sub will merge with and into InterQual in 
a transaction in which (i) all outstanding InterQual stock will be converted 
into the right to receive Access Health common stock and (ii) each share of 
Merger Sub common stock will be converted into one share of InterQual common 
stock.  All capitalized terms used but not defined herein have the meanings 
ascribed to them in the Reorganization Agreement.

     We have reviewed the discussion entitled "Certain Federal Income Tax 
Considerations" contained in the Registration Statement on Form S-4 of Access 
Health filed with the Securities and Exchange Commission. That discussion 
constitutes our opinion as to the material federal income tax consequences of 
the exchange of shares of InterQual Capital Stock for Access Health Common 
Stock pursuant to the Merger.
