    This Joint Proxy Statement/Prospectus/Information Statement is being
furnished to stockholders of Sun Healthcare Group, Inc., a Delaware corporation
("Sun"), in connection with the solicitation of proxies by the board of
directors of Sun for use at a special meeting of stockholders (the "Sun Special

Center, 101 Sun Avenue, N.E., Albuquerque, New Mexico, 87109, on June 26, 1998,
at 10:00 a.m., local time, and at any adjournments or postponements thereof, for
the purposes set forth herein and in the accompanying notice of special meeting
of stockholders of Sun.
 
    This Joint Proxy Statement/Prospectus/Information Statement is also being
furnished to shareholders of Retirement Care Associates, Inc., a Colorado
corporation ("RCA"), in connection with the solicitation of proxies by the board
of directors of RCA for use at the special meeting of shareholders (the "RCA
Special Meeting") of RCA to be held at RCA's principal offices located at 6000
Lake Forrest Drive, Suite 200, Atlanta, Georgia 30328, on June 26, 1998, at 8:30
a.m., local time, and at any adjournments or postponements thereof, for the
purposes set forth herein and in the accompanying notice of special meeting of
shareholders of RCA.
 
    This Joint Proxy Statement/Prospectus/Information Statement is also being
furnished to stockholders of Contour Medical, Inc., a Nevada corporation
("Contour"), in connection with the special meeting of stockholders (the
"Contour Special Meeting") of Contour to be held at RCA's principal offices
located at 6000 Lake Forrest Drive, Suite 200, Atlanta, Georgia 30328, on June
26, 1998, at 10:00 a.m., local time. STOCKHOLDERS OF CONTOUR ARE NOT BEING ASKED
FOR A PROXY AND ARE REQUESTED NOT TO SEND CONTOUR A PROXY.
 
    This Joint Proxy Statement/Prospectus/Information Statement also constitutes
a prospectus of Sun with respect to shares of Common Stock, par value $.01 per
share, of Sun (together with the associated Preferred Share Purchase Rights, the
"Sun Common Stock") and Series B Convertible Preferred Stock of Sun (the "Sun
Preferred Stock") to be issued in connection with the merger (the "RCA Merger")
of Peach Acquisition Corporation, a Colorado corporation and a direct
wholly-owned subsidiary of Sun ("RCA Merger Sub"), with and into RCA pursuant to
the Agreement and Plan of Merger and Reorganization, dated as of February 17,
1997, as amended by Amendment No. 1 thereto dated as of May 27, 1997, Amendment
No. 2 thereto dated as of August 21, 1997, Amendment No. 3 thereto dated as of
November 25, 1997 and Amendment No. 4 thereto dated as of April 3, 1998 (as
amended, the "RCA Merger Agreement"), among RCA, Sun and RCA Merger Sub. At the
effective time of the RCA Merger (the "RCA Effective Time"), (i) each
outstanding share of Common Stock, par value $.0001 per share, of RCA (the "RCA
Common Stock") will be converted into the number of shares of Sun Common Stock
equal to the quotient of $10.00 divided by the average of the last reported
sales prices of one share of Sun Common Stock on The New York Stock Exchange
(the "NYSE") during the period of the 20 most recent trading days ending five
business days before the RCA Effective Time (the "Sun Market Price") (unless the
Sun Market Price exceeds $24.20 per share, in which case each outstanding share
of RCA Common Stock will be converted into 0.413 shares of Sun Common Stock, or
unless the Sun Market Price is less than $19.80 per share, in which case each
outstanding share of RCA Common Stock will be converted into 0.505 shares
<PAGE>
of Sun Common Stock), subject to further adjustment under certain circumstances
as described below (as adjusted, if at all, the "RCA Common Exchange Ratio"),
(ii) each outstanding share of Series AA Redeemable Preferred Stock of RCA (the
"RCA Series AA Preferred Stock") will be converted into the number of shares of
Sun Common Stock equal to the quotient of $10.00 divided by the Sun Market
Price, (iii) each outstanding share of Series F Convertible Preferred Stock of
RCA (the "RCA Series F Preferred Stock" and, together with the RCA Common Stock
and RCA Series AA Preferred Stock, the "RCA Capital Stock") will be converted
into one share of Sun Preferred Stock, which shares of Sun Preferred Stock shall
thereafter be convertible into the number of shares of Sun Common Stock that
such shares of RCA Series F Preferred Stock would have been converted into if
converted immediately prior to the RCA Effective Time (see "Description of Sun
Capital Stock--Series B Convertible Preferred Stock"), (iv) each outstanding
option and warrant to purchase RCA Common Stock will be assumed by Sun and
converted into an option or warrant, as the case may be, to purchase the number
of shares of Sun Common Stock equal to the product of the number of shares of
RCA Common Stock subject to such option or warrant immediately prior to the RCA
Effective Time multiplied by the RCA Common Exchange Ratio, and (v) RCA will
become a wholly-owned subsidiary of Sun.
 
    If the RCA Merger had been consummated on May 20, 1998, when the Sun Market
Price was $17.725, each outstanding share of RCA Common Stock would have been
converted into 0.505 shares of Sun Common Stock, each outstanding share of RCA
Series AA Preferred Stock would have been converted into 0.564 shares of Sun
Common Stock, each outstanding share of RCA Series F Preferred Stock would have
been converted into one share of Sun Preferred Stock (each share of which would
have been convertible into 0.857 shares of Sun Common Stock), and an aggregate
of 8,983,648 shares of Sun Common Stock (including shares of Sun Common Stock
issuable upon conversion of the shares of Sun Preferred Stock issued in the RCA
Merger) with an aggregate market value of approximately $158.9 million would
have been issued to the holders of RCA Capital Stock in the RCA Merger (based
upon the number of shares of RCA Capital Stock outstanding on a fully-diluted
basis as of such date). In the event that the Sun Market Price is greater than
$19.80 per share, but less than $24.20 per share, as of the RCA Effective Time,
each outstanding share of RCA Common Stock will be converted into the number of
shares of Sun Common Stock equal to the quotient of $10.00 divided by the Sun
Market Price, and each outstanding share of RCA Series F Preferred Stock will be
converted into one share of Sun Preferred Stock (each share of which would have
been convertible into between .701 and .857 shares of Sun Common Stock). In the
event that the Sun Market Price is greater than $24.20 per share as of the RCA
Effective Time, each outstanding share of RCA Common Stock will be converted
into 0.413 shares of Sun Common Stock, and each outstanding share of RCA Series
F Preferred Stock will be converted into one share of Sun Preferred Stock (each
share of which will be convertible into 0.701 shares of Sun Common Stock). In
addition, the RCA Common Exchange Ratio is subject to adjustment in the event
that the average of the last reported sales prices of one share of Sun Common
Stock on the NYSE during the period of the 20 most recent trading days ending on
the fifth business day prior to the RCA Effective Time is less than $14.00. In
such event, the RCA Common Exchange Ratio will decrease by the "Adjustment
Amount" (as defined under "The RCA Merger--Conversion of RCA Capital Stock"). In
the event that the Sun Market Price is below $19.80 per share or greater than
$24.20 per share as of the RCA Effective Time, the number of shares of Sun
Common Stock (including shares of Sun Common Stock issuable upon conversion of
the shares of Sun Preferred Stock issued in the RCA Merger) that holders of RCA
Capital Stock would receive in the RCA Merger will be fixed (subject to
adjustment under certain circumstances as described herein), in which case, the
value of the shares of Sun Common Stock (including shares of Sun Common Stock
issuable upon conversion of the shares of Sun Preferred Stock issued in the RCA
Merger) that holders of RCA Capital Stock will receive in the RCA Merger may
increase or decrease prior to the RCA Effective Time cause the market price of
the Sun Common Stock is subject to fluctuation. In the event that the Sun Market
Price is greater than $19.80 per share but less than $24.20 per share as of the
RCA Effective Time, the value of the shares of Sun Common Stock (including
shares of Sun Common Stock issuable upon conversion of the shares of Sun
Preferred Stock issued in the RCA Merger) that holders of RCA Capital
 
                                       2
<PAGE>
Stock would receive in the RCA Merger will be fixed, in which case the number of
shares of Sun Common Stock (including shares of Sun Common Stock issuable upon
conversion of the shares of Sun Preferred Stock issued in the RCA Merger) that
holders of RCA Capital Stock will receive in the RCA Merger may increase or
decrease prior to the RCA Effective Time because the market price of the Sun
Common Stock is subject to fluctuation. Holders of RCA Capital Stock are advised
to obtain current market quotations for the Sun Common Stock. See "The RCA
Merger--Conversion of RCA Capital Stock."
 
    The proposed RCA Merger is contingent upon, among other things, the approval
of the holders of the requisite number of shares of Sun Common Stock and RCA
Capital Stock, all as described in this Joint Proxy
Statement/Prospectus/Information Statement. Concurrently with the execution of
the RCA Merger Agreement, Sun entered into a Stockholders' Stock Option and
Proxy Agreement (the "RCA Stock Option Agreement"), with Christopher F. Brogdon,
Connie Brogdon, Edward E. Lane, Darrell C. Tucker and Winter Haven Homes Inc.,
collectively owners as of such date of approximately 36% of the outstanding
shares of RCA Capital Stock, pursuant to which each such stockholder agreed to
vote, and granted to Sun an irrevocable proxy to vote, all voting securities of
RCA held by such stockholders in favor of approval of the RCA Merger Agreement
and the RCA Merger. The proposed RCA Merger will be consummated as soon as
practicable after such approvals are obtained and the other conditions to the
RCA Merger are satisfied or waived. It is expected that the RCA Merger will
occur promptly after the consummation of the Contour Merger. THE CONSUMMATION OF
THE CONTOUR MERGER DISCUSSED BELOW IS NOT A CONDITION TO THE RCA MERGER.
 
    This Joint Proxy Statement/Prospectus/Information Statement also constitutes
a prospectus of Sun with respect to shares of Sun Common Stock to be issued in
connection with the merger (the "Contour Merger") of Nectarine Acquisition
Corporation, a Nevada corporation and a direct wholly-owned subsidiary of Sun
("Contour Merger Sub"), with and into Contour pursuant to the Agreement and Plan
of Merger and Reorganization, dated as of February 17, 1997, as amended by
Amendment No. 1 thereto dated as of August 21, 1997, Amendment No. 2 thereto
dated as of November 25, 1997 and Amendment No. 3 thereto dated as of April 3,
1998 (as amended, the "Contour Merger Agreement"), among Contour, Sun and
Contour Merger Sub. At the effective time of the Contour Merger (the "Contour
Effective Time"), (i) each outstanding share of Common Stock, par value $.001
per share, of Contour (the "Contour Common Stock"), other than shares owned by
RCA, will be converted into the number of shares of Sun Common Stock equal to
the quotient of $8.50 divided by the Sun Market Price (the "Contour Common
Exchange Ratio"), (ii) each outstanding share of Series A Convertible Preferred
Stock of Contour (the "Contour Preferred Stock" and, together with the Contour
Common Stock, the "Contour Capital Stock"), other than shares owned by RCA, will
be converted into the number of shares of Sun Common Stock equal to the quotient
of $4.00 divided by the Sun Market Price, (iii) each outstanding share of
Contour Capital Stock owned by RCA will not be exchanged in the Contour Merger
and will remain outstanding (unless (x) the RCA Merger does not occur promptly
after consummation of the Contour Merger, or (y) Sun does not undertake to
contribute to RCA all shares of Contour Capital Stock acquired by Sun pursuant
to the Contour Merger, in which event RCA would receive the same per share
consideration as the other holders of Contour Capital Stock pursuant to (i) and
(ii)), (iv) each outstanding option and warrant to purchase Contour Common Stock
will be assumed by Sun and converted into an option or warrant, as the case may
be, to purchase the number of shares of Sun Common Stock equal to the product of
the number of shares of Contour Common Stock subject to such option or warrant
immediately prior to the Contour Effective Time multiplied by the Contour Common
Exchange Ratio, and (v) Contour will become a wholly owned subsidiary of Sun.
 
    If the Contour Merger had been consummated on May 20, 1998, when the Sun
Market Price was $17.725, each outstanding share of Contour Common Stock, other
than shares owned by RCA, would have been converted into 0.480 shares of Sun
Common Stock, each outstanding share of Contour Preferred Stock, other than
shares owned by RCA, would have been converted into 0.226 shares of Sun Common
Stock, and an aggregate of 1,943,482 shares of Sun Common Stock with an
aggregate market value of
 
                                       3
<PAGE>
approximately $34.4 million would have been issued to the holders of Contour
Capital Stock (other than RCA, which owns approximately 65% of the issued and
outstanding Contour Capital Stock) in the Contour Merger (based upon the number
of shares of Contour Capital Stock outstanding on a fully-diluted basis as of
such date). Because the value of the shares of Sun Common Stock that holders of
Contour Capital Stock will receive in the Contour Merger is fixed and because
the market price of the Sun Common Stock is subject to fluctuation, the number
of shares of Sun Common Stock that holders of Contour Capital Stock will receive
in the Contour Merger may increase or decrease prior to the Contour Effective
Time. The number of shares of Sun Common Stock that will be issued in exchange
for the Contour Common Stock in the Contour Merger is not subject to any cap or
floor. Holders of Contour Capital Stock are advised to obtain current market
quotations for the Sun Common Stock. See "The Contour Merger--Conversion of
Contour Capital Stock."
 
    The proposed Contour Merger is contingent upon, among other things, the
approval of the holders of the requisite number of shares of Sun Common Stock
and Contour Capital Stock, as described in this Joint Proxy
Statement/Prospectus/Information Statement. Concurrently with the execution of
the Contour Merger Agreement, Sun entered into a Stockholder Stock Option and
Proxy Agreement (the "Contour Stock Option Agreement") with RCA, pursuant to
which RCA agreed to vote, and granted to Sun an irrevocable proxy to vote, all
of the 5,222,003 shares of Contour Common Stock and 85,000 shares of Contour
Preferred Stock owned by RCA in favor of the Contour Merger Agreement and the
Contour Merger. AS A RESULT, SUN HAS THE RIGHT TO VOTE AT THE CONTOUR SPECIAL
MEETING SUFFICIENT SHARES TO APPROVE THE CONTOUR MERGER AGREEMENT WITHOUT THE
AFFIRMATIVE VOTE OF ANY OTHER STOCKHOLDER, THEREBY ASSURING THE APPROVAL OF THE
CONTOUR MERGER AGREEMENT AND THE CONTOUR MERGER. The proposed Contour Merger
will be consummated as soon as practicable after such approvals are obtained and
the other conditions to the Contour Merger are satisfied or waived. It is
expected that the Contour Merger will occur immediately prior to the
consummation of the RCA Merger. THE CONSUMMATION OF THE RCA MERGER IS NOT A
CONDITION TO THE CONTOUR MERGER.
 
    On February 14, 1997, the last full trading day prior to the public
announcement of the execution of the RCA Merger Agreement and the Contour Merger
Agreement, the last reported sale prices on the NYSE of Sun Common Stock and RCA
Common Stock were $14.00 and $9.00, respectively, and the last reported bid
price on The Nasdaq Small-Cap Market of Contour Common Stock was $7.00. On
November 25, 1997, the last full trading day prior to the public announcement of
the execution of Amendment No. 3 to the RCA Merger Agreement (which Amendment
established the consideration to be received by the holders of RCA Capital Stock
in the RCA Merger), the last reported sale prices on the NYSE of Sun Common
Stock and RCA Common Stock were $21.00 and $8.25, respectively.
 
    RCA owns approximately 65% of the issued and outstanding Contour Capital
Stock as of the date of this Joint Proxy Statement/Prospectus/Information
Statement. Following the consummation of each of the RCA Merger and the Contour
Merger, each of RCA and Contour will be wholly-owned subsidiaries of Sun.
 
    BASED ON THE CLOSING PRICE AND THE NUMBER OF OUTSTANDING SHARES OF SUN
COMMON STOCK ON MAY 20, 1998, AND ASSUMING THE CONVERSION INTO COMMON STOCK, OR
ISSUANCE OF COMMON STOCK UPON EXERCISE, OF ALL "IN THE MONEY" SECURITIES OF RCA
AND CONTOUR, THE MAXIMUM NUMBER OF SHARES OF SUN COMMON STOCK THAT WILL BE
OUTSTANDING, NET OF TREASURY SHARES, UPON CONSUMMATION OF THE RCA MERGER AND THE
CONTOUR MERGER IS 60,192,612.

STATEMENT/PROSPECTUS/ INFORMATION STATEMENT UNDER "RISK FACTORS."
 
THE COMPANIES
 
    SUN
 
    Sun Healthcare Group, Inc., through its direct and indirect subsidiaries
(collectively referred to herein as "Sun"), is a leading provider of
high-quality and cost-efficient long-term, subacute and related specialty
healthcare services in the United States and the United Kingdom, and also has
operations in Spain, Germany and Australia. At March 31, 1998, Sun operated 318
long-term and subacute care facilities (which includes assisted living and
managed facilities) with 36,488 licensed beds in the United States and 177
long-term and acute care facilities with 11,132 licensed beds internationally.
Sun is one of the largest providers of ancillary services to long-term care
providers in the United States, including the provision of rehabilitation
therapy (the provision of physical, occupational and speech therapy),
respiratory therapy (the provision of respiratory therapy and the distribution
of related equipment and supplies), temporary therapy staffing services and
pharmaceutical products and services. Sun provides these services to over 1,500
affiliated and nonaffiliated long-term and subacute care facilities in the
United States. After giving pro forma effect to the Regency Acquisition (as
defined), which closed in the fourth quarter of 1997, Sun's revenues for the
year ended December 31, 1997 would have been approximately $2.5 billion.
 
    Sun's inpatient care facilities provide a broad range of healthcare
services, including nursing care, subacute care, therapy and other specialized
services such as care to patients with Alzheimer's disease. Sun's long-term and
subacute care operations have experienced significant growth since Sun's
inception in 1989, primarily from acquisitions of additional facilities. Sun
believes its inpatient care operations provide it with a platform to expand its
therapy and pharmaceutical businesses (which include dispensing
 
                                       13
<PAGE>
pharmaceuticals for such purposes as infusion therapy, pain management,
antibiotic therapy and parenteral nutrition) to affiliated and nonaffiliated
long-term and subacute care facilities. Sun believes that its expertise in
operating long-term and subacute care facilities enables it to provide its
therapy and pharmaceutical services more effectively and efficiently than
providers without such operating expertise.
 
    Through CareerStaff Unlimited, Inc. ("CareerStaff"), Sun is a nationwide
provider of temporary therapy staffing. CareerStaff provides licensed therapists
skilled in the areas of physical, occupational and speech therapy primarily to
hospitals and nursing home contract service providers. At March 31, 1998, Sun
had 29 division offices providing temporary therapy staffing services in major
metropolitan areas and four division offices specializing in placements of
temporary traveling therapists in smaller cities and rural areas.
 
    Through SunScript Pharmacy Corporation ("SunScript"), as of March 31, 1998,
Sun operated 42 pharmacies and one pharmaceutical billing and consulting center
which together provided pharmaceutical products and services to a total of 840
long-term and subacute care facilities in 27 states, 576 of which were
nonaffiliated. In addition, Sun operated 19 pharmacies and one supply
distribution center in the United Kingdom at December 31, 1997.
 
    In October 1997, Sun acquired (the "Regency Acquistion") Regency Health
Services, Inc. ("Regency"), an operator of skilled nursing facilities and a
diversified provider of rehabilitation therapy, institutional pharmacy and home
health services, for approximately $575 million, including approximately $345
million in cash ($22.00 per Regency share) and the assumption or refinancing of
approximately $230 million of Regency's indebtedness. See "Unaudited Pro Forma
Combined Financial Statements." Pursuant to the Regency Acquisition, Sun
acquired 110 long-term care facilities with 11,440 beds, 26 outpatient
rehabilitation therapy clinics and eight institutional pharmacies. As of
September 30, 1997, Regency had rehabilitation therapy contracts with 202
facilities and pharmacy contracts with 162 facilities. Sun financed the Regency
Acquisition, as well as the repayment of Sun's outstanding borrowings under
Sun's prior $490 million revolving credit facility, through borrowings under a
new $1.2 billion credit facility (the "Credit Facility") and $83 million of net
proceeds received from the sale and leaseback of 30 facilities owned by Regency
prior to its acquisition by Sun. In connection with the Regency Acquisition, Sun
also acquired in a tender offer $160 million of Regency's subordinated debt,
which was subsequently retired. See "Risk Factors -- Difficulty of Integrating
Acquired Operations."
 
    In 1997, Sun expanded its international operations by acquiring 83
facilities in the United Kingdom, Spain, Australia and Germany. Sun operates 152
facilities with 8,517 licensed beds as of March 31, 1998. Sun's growth in the
United Kingdom is due in large part to its acquisitions of APTA Healthcare PLC
("APTA") in December 1996 and Ashbourne PLC ("Ashbourne") in January 1997, which
together added 81 long-term care facilities with 4,877 licensed beds to Sun's
operations.
 
    In July 1997, Sun acquired a majority interest in Eurosar, S.A. ("Eurosar"),
a privately-owned operator of eight long-term care facilities in Spain with
1,328 licensed beds. In August 1997, Sun acquired 38% of the equity of Alpha
Healthcare Limited ("Alpha"), a publicly held acute care provider in Australia
that operated ten facilities with 686 licensed beds. In November 1997, Sun
acquired from Moran Health Care Group Pty Ltd. ("Moran") a majority interest in
six hospitals in Australia. In December 1997, Sun acquired a majority interest
in Heim Plan -- Uternehmensgruppe, an operator of 11 long-term facilities with
930 licensed beds in Germany.
 
    The principal executive offices of Sun are located at 101 Sun Avenue, N.E.,
Albuquerque, New Mexico 87109, and its telephone number at that location is
(505) 821-3355. As used in this Joint Proxy Statement/Prospectus/Information
Statement, the term "Sun" refers to Sun Healthcare Group, Inc. and its direct
and indirect subsidiaries, unless the context otherwise requires.

one share of Sun Common Stock on The New York Stock Exchange (the "NYSE") during
the period of the 20 most recent trading days ending five business days before
the RCA Effective Time (the "Sun Market Price") (unless the Sun Market Price
exceeds $24.20 per share, in which case each outstanding share of RCA Common
Stock will be converted into 0.413 shares of Sun Common Stock, or unless the Sun
Market Price is less than $19.80 per share, in which case each outstanding share
of RCA Common Stock will be converted into 0.505 shares of Sun Common Stock),
subject to further adjustment under certain circumstances as described below
(the "RCA Common Exchange Ratio"), (ii) each outstanding share of Series AA
Redeemable Preferred Stock of RCA (the "RCA Series AA Preferred Stock") will be
converted into the number of shares of Sun Common Stock equal to the quotient of
$10.00 divided by the Sun Market Price, (iii) each outstanding share of Series F
Convertible Preferred Stock of RCA (the "RCA Series F Convertible Preferred
Stock" and, together with the RCA Common Stock and RCA Series AA Preferred
Stock, the "RCA Capital Stock") will be converted into one share of Series B
Convertible Preferred Stock of Sun (the "Sun Preferred Stock"), which shares of
Sun Preferred Stock shall thereafter be convertible into the number of shares of
Sun Common Stock that such shares of RCA Series F Preferred Stock would have
been converted into if
 
                                       15
<PAGE>
converted immediately prior to the RCA Effective Time, see "Description of Sun
Capital Stock--Series B Convertible Preferred Stock," (iv) each outstanding
option and warrant to purchase RCA Common Stock will be assumed by Sun and
converted into an option or warrant, as the case may be, to purchase the number
of shares of Sun Common Stock equal to the product of the number of shares of
RCA Common Stock subject to such option or warrant immediately prior to the RCA
Effective Time multiplied by the RCA Common Exchange Ratio (as defined below),
and (v) RCA will become a wholly-owned subsidiary of Sun. See "The RCA Merger"
and "The RCA Merger Agreement."
 
    If the RCA Merger had been consummated on May 20, 1998, when the RCA Market
Price was $17.725, each outstanding share of RCA Common Stock would have been
converted into 0.505 shares of Sun Common Stock, each outstanding share of RCA
Series AA Preferred Stock would have been converted into 0.564 shares of Sun
Common Stock, each outstanding share of RCA Series F Preferred Stock would have
been converted into one share of Sun Preferred Stock (each share of which would
have been convertible into 0.857 shares of Sun Common Stock, and an aggregate of
8,983,648 shares of Sun Common Stock (including shares of Sun Common Stock
issuable upon conversion of the shares of Sun Preferred Stock issued in the RCA
Merger) with an aggregate market value of approximately $158.9 million would
have been issued to the holders of RCA Capital Stock in the RCA Merger (based
upon the number of shares of RCA Capital Stock outstanding on a fully-diluted
basis as of such date). In the event that the Sun Market Price is greater than
$19.80 per share, but less than $24.20 per share, as of the RCA Effective Time,
each outstanding share of RCA Common Stock will be converted into the number of
shares of Sun Common Stock equal to the quotient of $10.00 divided by the Sun
Market Price, and each outstanding share of RCA Series F Preferred Stock will be
converted into one share of Sun Preferred Stock (each share of which would have
been convertible into between .701 and .857 shares of Sun Common Stock. In the
event that the Sun Market Price is greater than $24.20 per share as of the RCA
Effective Time, each outstanding share of RCA Common Stock will be converted
into 0.413 shares of Sun Common Stock, and each outstanding share of RCA Series
F Preferred Stock will be converted into one share of Sun Preferred Stock (each
share of which will be convertible into 0.701 shares of Sun Common Stock). In
addition, the RCA Common Exchange Ratio is subject to adjustment in the event
that the average of the last reported sales prices of one share of Sun Common
Stock on the NYSE during the period of the 20 most recent trading days ending on
the fifth business day prior to the RCA Effective Time is less than $14.00. In
such event, the RCA Common Exchange Ratio will decrease by the "Adjustment
Amount" (as defined under "The RCA Merger--Conversion of RCA Capital Stock"). In
the event that the Sun Market Price is below $19.80 per share or greater than
$24.20 per share as of the RCA Effective Time, the number of the shares of Sun
Common Stock (including shares of Sun Common Stock issuable upon conversion of
the shares of Sun Preferred Stock issued in the RCA Merger) that holders of RCA
Capital Stock would receive in the RCA Merger will be fixed, in which case the
number of shares of Sun Common Stock (including shares of Sun Common Stock
issuable upon conversion of the shares of Sun Preferred Stock issued in the RCA
Merger) that holders of RCA Capital Stock will receive in the RCA Merger may
increase or decrease prior to the RCA Effective Time cause the market price of
the Sun Common Stock is subject to fluctuation. In the event that the Sun Market
Price is greater than $19.80 per share but less than $24.20 per share as of the
RCA effective time, the number of the shares of Sun Common Stock (including
shares of Sun Common Stock issuable upon conversion of the shares of Sun
Preferred Stock issued in the RCA Merger) that holders of RCA Capital Stock
would receive in the RCA Merger will be fixed, in which case the number of
shares of Sun Common stock (including shares of Sun Common Stock issuable upon
conversion of the shares of Sun Preferred Stock issued in the RCA Merger) that
holders of RCA Capital Stock will receive in the RCA Merger may increase or
decrease prior to the RCA Effective Time because the market price of the Sun
Common Stock is subject to fluctuation. Holders of RCA Capital Stock are advised
to obtain current market quotations for the Sun Common Stock. See "The RCA
Merger-- Conversion of RCA Capital Stock."
 
    The following table sets forth the number of shares of Sun Common Stock
(including shares of Sun Common Stock issuable upon conversion of the shares of
Sun Preferred Stock issued in the RCA Merger)

    decrease in the RCA Common Exchange Ratio by the Adjustment Amount. See "The
    RCA Merger--Conversion of RCA Capital Stock."
 
(b) Assumes that the RCA Merger has been consummated on May 20, 1998. Because
    the conversion price of the RCA Series F Preferred Stock is based in part on
    the average closing bid price of the RCA Common Stock on the NYSE for the
    five consecutive trading days immediately prior to the RCA Effective Time,
    the number of shares of Sun Common Stock issuable upon conversion of each
    share of Sun Preferred Stock issued with respect to shares of RCA Series F
    Preferred Stock may differ from that set forth above. See "Description of
    Sun Capital Stock--Series B Convertible Preferred Stock."
 
OVERVIEW OF THE CONTOUR MERGER
 
    Pursuant to the Agreement and Plan of Merger and Reorganization, dated as of
February 17, 1997, as amended by Amendment No. 1 thereto dated as of August 21,
1997, Amendment No. 2 thereto dated as of November 25, 1997 and Amendment No. 3
thereto dated as of April 3, 1998 (as amended, the "Contour Merger Agreement"),
among Contour, Sun and Nectarine Acquisition Corporation ("Contour Merger Sub"),
Contour Merger Sub will be merged (the "Contour Merger") with and into Contour,
and at the effective time thereof (the "Contour Effective Time") (i) each
outstanding share of Common Stock, par value $.001 per share, of Contour (the
"Contour Common Stock"), other than shares owned by RCA, will be converted to
receive the number of shares of Sun Common Stock equal to the quotient of $8.50
divided by the Sun Market Price (the "Contour Common Exchange Ratio"), (ii) each
outstanding share of Series A Convertible Preferred Stock of Contour (the
"Contour Preferred Stock" and, together with the Contour Common Stock, the
"Contour Capital Stock"), other than shares owned by RCA, will be converted to
receive the number of shares of Sun Common Stock equal to the quotient of $4.00
divided by the Sun Market Price, (iii) each outstanding share of Contour Capital
Stock owned by RCA will not be exchanged in the Contour Merger and will remain
outstanding (unless (x) the RCA Merger does not occur promptly after
consummation of the Contour Merger, or (y) Sun does not undertake to contribute
to RCA all shares of Contour Capital Stock acquired by Sun pursuant to the
Contour Merger, in which event RCA would receive the same per share
consideration as the other holders of Contour Capital Stock pursuant to (i) and
(ii)), (iv) each outstanding option and warrant to purchase Contour Common Stock
will be assumed by Sun and converted into an option or warrant, as the case may
be, to purchase the number of shares of Sun Common Stock equal to the product of
the number of shares of Contour Common Stock subject to such option or warrant
immediately prior to the Contour Effective Time multiplied by the
 
                                       17
<PAGE>
Contour Common Exchange Ratio, and (v) Contour will become a wholly-owned
subsidiary of Sun. See "The Contour Merger" and "The Contour Merger Agreement."
 
    If the Contour Merger had been consummated on May 20, 1998, when the Sun
Market Price was $17.725, each outstanding share of Contour Common Stock, other
than shares owned by RCA, would have been converted into 0.480 shares of Sun
Common Stock, each outstanding share of Contour Preferred Stock, other than
shares owned by RCA, would have been converted into 0.226 shares of Sun Common
Stock, and an aggregate of 1,943,482 shares of Sun Common Stock with an
aggregate market value of approximately $34.4 million would have been issued to
the holders of Contour Capital Stock (other than RCA, which owns approximately
65% of the issued and outstanding Contour Capital Stock) in the Contour Merger
(based upon the number of shares of Contour Capital Stock outstanding on a
fully-diluted basis as of such date). Because the value of the shares of Sun
Common Stock that holders of Contour Capital Stock will receive in the Contour
Merger is fixed and because the market price of the Sun Common Stock is subject
to fluctuation, the number of shares of Sun Common Stock that holders of Contour
Capital Stock will receive in the Contour Merger may increase or decrease prior
to the Contour Effective Time. The number of shares of Sun Common Stock that
will be issued in exchange for the Contour Common Stock in the Contour Merger is
not subject to any cap or floor. Holders of Contour Capital Stock are advised to
obtain current market quotations for the Sun Common Stock. See "The Contour
Merger--Conversion of Contour Capital Stock."
 
    The following table sets forth the number of shares of Sun Common Stock that
shares of Contour Capital Stock would be converted into upon consummation of the
Contour Merger at each of the hypothetical Sun Market Prices set forth below.

THE SUN SPECIAL MEETING
 
    DATE AND PLACE OF THE MEETING.  The special meeting of stockholders of Sun
(the "Sun Special Meeting") will be held at Sun's Rev. Dr. Kay M. Glaesner, Jr.
Training Center, 101 Sun Avenue, N.E., Albuquerque, New Mexico, 87109, on June
26, 1998, at 10:00 a.m., local time.
 
    STOCKHOLDERS ENTITLED TO VOTE.  The record date for determination of holders
of Sun Common Stock entitled to vote at the Sun Special Meeting is May 1, 1998
(the "Sun Record Date"). As of the close of business on the Sun Record Date,
49,593,954 shares of Sun Common Stock were outstanding, held by approximately
4,993 holders of record. Only holders of record of Sun Common Stock as of the
close of business on the Sun Record Date are entitled to notice of and to vote
at the Sun Special Meeting and any adjournments or postponements thereof.
 
    PURPOSE OF THE MEETING.  The purpose of the Sun Special Meeting is to
consider and vote upon proposals (i) to approve and adopt the RCA Merger
Agreement and to approve the RCA Merger and the issuance of Sun Common Stock and
Sun Preferred Stock pursuant thereto; (ii) to approve and adopt the
 
                                       18
<PAGE>
Contour Merger Agreement and to approve the Contour Merger and the issuance of
Sun Common Stock pursuant thereto; (iii) to approve an amendment to Sun's
Certificate of Incorporation to increase the number of authorized shares of Sun
Common Stock; and (iv) to transact such other business as may properly come
before the Sun Special Meeting or any adjournments or postponements thereof.
 
    VOTE REQUIRED.  The approval of the RCA Merger Agreement, and the RCA
Merger, and the issuance of shares of Sun Common Stock and Sun Preferred Stock
pursuant to the RCA Merger, and the approval of the Contour Merger Agreement and
the Contour Merger, and the issuance of shares of Sun Common Stock pursuant to
the Contour Merger, will each require the affirmative vote of a majority of the
shares of Sun Common Stock present in person or represented by properly executed
proxy at the Sun Special Meeting. The approval of the amendment to Sun's
Certificate of Incorporation will require the affirmative vote of a majority of
the outstanding shares of Sun Common Stock. See "The Meetings--The Sun Special
Meeting--Voting; Vote Required."
 
    Shares of Sun Common Stock that are voted "FOR," "AGAINST" or "WITHHELD" at
the Sun Special Meeting will be treated as being present at such meeting for
purposes of establishing a quorum and will also be treated as votes eligible to
be cast by the Sun Common Stock present in person or represented by proxy at the
Sun Special Meeting and entitled to vote on the subject matter. Abstentions will
be counted for purposes of determining both the presence or absence of a quorum
for the transaction of business and the total number of votes cast with respect
to a particular matter. Broker non-votes will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business,
but will not be counted for purposes of determining the number of votes cast
with respect to the particular proposal on which the broker has expressly not
voted. Broker non-votes with respect to proposals set forth in this Joint Proxy
Statement/Prospectus/Information Statement will therefore not be considered
votes cast and, accordingly, will not affect the determination as to whether a
majority of votes cast has been obtained with respect to a particular matter,
other than with respect to the approval of the amendment to Sun's Certificate of
Incorporation, which approval will require the affirmative vote of a majority of
the outstanding shares of Sun Common Stock.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the Sun Record Date, directors and executive officers of
Sun and their respective affiliates may be deemed to be the beneficial owners of
shares of Sun Common Stock representing approximately 15.5% of the outstanding
voting power of Sun. Each of the directors and executive officers of Sun has
indicated that such person intends to vote or direct the vote of all the shares
of Sun Common Stock over which such person has voting control in favor of the
RCA Merger Agreement, and the RCA Merger, and the issuance of shares of Sun
Common Stock and Sun Preferred Stock pursuant to the RCA Merger, the Contour
Merger Agreement and the Contour Merger, and the issuance of shares of Sun
Common Stock pursuant to the Contour Merger, and the approval of the amendment
to Sun's Certificate of Incorporation.
 
THE RCA SPECIAL MEETING
 
    DATE AND PLACE OF THE MEETING.  The special meeting of shareholders of RCA
(the "RCA Special Meeting") will be held at RCA's principal offices located at
6000 Lake Forrest Drive, Suite 200, Atlanta, Georgia 30328, on June 26, 1998, at
8:30 a.m., local time.
 
    SHAREHOLDERS ENTITLED TO VOTE.  The record date for determination of holders
of RCA Capital Stock entitled to vote at the RCA Special Meeting is May 12, 1998
(the "RCA Record Date"). As of the close of business on the RCA Record Date, (i)
14,798,525 shares of RCA Common Stock were outstanding, held by approximately
269 holders of record; (ii) 120,000 shares of RCA Series AA Preferred Stock were
outstanding, held by approximately seven holders of record; and (iii) 298,334
shares of RCA Series F Preferred Stock were outstanding, held by approximately
three holders of record. Only holders of record of RCA Capital Stock as of the
close of business on the RCA Record Date are entitled to notice of and to vote
at the RCA Special Meeting and any adjournments or postponements thereof.
 
                                       19
<PAGE>
    PURPOSE OF THE MEETING.  The purpose of the RCA Special Meeting is to
consider and vote upon proposals (i) to approve and adopt the RCA Merger
Agreement and to approve the RCA Merger; and (ii) to transact such other
business as may properly come before the RCA Special Meeting or any adjournments
or postponements thereof.
 
    VOTE REQUIRED.  The approval of the RCA Merger Agreement and the RCA Merger
will require the affirmative vote of a majority of the outstanding shares of RCA
Capital Stock (with the RCA Series AA Preferred Stock and RCA Series F Preferred
Stock voting on an as-converted basis), voting together as a single class. See
"The Meetings--The RCA Special Meeting--Voting; Vote Required." Concurrently
with the execution of the RCA Merger Agreement, Sun entered into a Stockholders'
Stock Option and Proxy Agreement (the "RCA Stock Option Agreement") with
Christopher F. Brogdon, Connie B. Brogdon, Edward E. Lane, Darrell C. Tucker and
Winter Haven Homes Inc., collectively owners as of such date of approximately
36% of the outstanding shares of RCA Capital Stock, pursuant to which each such
stockholder agreed to vote, and granted to Sun an irrevocable proxy to vote, all
voting securities of RCA held by such stockholders in favor of approval of the
RCA Merger Agreement and the RCA Merger. See "The RCA Stockholders' Stock Option
and Proxy Agreement."
 
    Shares of RCA Capital Stock that are voted "FOR," "AGAINST" or "WITHHELD" at
the RCA Special Meeting will be treated as being present at such meeting for
purposes of establishing a quorum and will also be treated as votes eligible to
be cast by the RCA Capital Stock present in person at the RCA Special Meeting
and entitled to vote on the subject matter. Abstentions will be counted for
purposes of determining both the presence or absence of a quorum for the
transaction of business and the total number of votes cast with respect to a
particular matter. Broker non-votes will be counted for purposes of determining
the presence or absence of a quorum for the transaction of business, but will
not be counted for purposes of determining the number of votes cast with respect
to the particular proposal on which the broker has expressly not voted.
Abstentions and broker non-votes will have the same effect as a vote against the
approval of the RCA Merger Agreement and the RCA Merger, which approval will
require the affirmative vote of a majority of the outstanding shares of RCA
Capital Stock (with the RCA Series AA Preferred Stock and RCA Series F Preferred
Stock voting on an as-converted basis), voting together as a single class.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the RCA Record Date, directors and executive officers of
RCA and their respective affiliates may be deemed to be the beneficial owners of
shares of RCA Capital Stock representing approximately 31.9% of the outstanding
voting power of RCA. Each of the directors and executive officers of RCA has
indicated that such person intends to vote or direct the vote of all the shares
of RCA Capital Stock over which such person has voting control in favor of the
RCA Merger Agreement and the RCA Merger. In addition, concurrently with the
execution of the RCA Merger Agreement, Sun and the owners as of such date of
approximately 36% of the outstanding shares of RCA Capital Stock entered into
the RCA Stock Option Agreement, pursuant to which each such stockholder granted
to Sun the right to vote all of the voting securities of RCA held by such
stockholders in favor of the RCA Merger Agreement and the RCA Merger. See "The
RCA Stockholders' Stock and Proxy Option Agreement."
 
THE CONTOUR SPECIAL MEETING
 
    DATE AND PLACE OF THE MEETING.  The special meeting of stockholders of
Contour (the "Contour Special Meeting") will be held at the principal offices of
RCA, located at 6000 Lake Forrest Drive, Suite 200, Atlanta, Georgia 30328, on
June 26, 1998, at 10:00 a.m., local time.
 
    STOCKHOLDERS ENTITLED TO VOTE.  The record date for determination of holders
of Contour Capital Stock entitled to vote at the Contour Special Meeting is May
1, 1998 (the "Contour Record Date"). As of the close of business on the Contour
Record Date, (i) 8,309,081 shares of Contour Common Stock were outstanding, held
by approximately 104 holders of record and (ii) 120,000 shares of Contour
Preferred
 
                                       20
<PAGE>
Stock were outstanding, held by approximately six holders of record. Only
holders of record of Contour Capital Stock as of the close of business on the
Contour Record Date are entitled to notice of and to vote at the Contour Special
Meeting and any adjournments or postponements thereof.
 
    PURPOSE OF THE MEETING.  The purpose of the Contour Special Meeting is to
consider and vote upon proposals (i) to approve and adopt the Contour Merger
Agreement and to approve the Contour Merger; and (ii) to transact such other
business as may properly come before the Contour Special Meeting or any
adjournments or postponements thereof.
 
    VOTE REQUIRED.  The approval of the Contour Merger Agreement and the Contour
Merger will require the affirmative vote of a majority of the outstanding shares
of Contour Capital Stock (with the Contour Preferred Stock voting on an
as-converted basis), voting together as a single class. See "The Meetings--The
Contour Special Meeting--Voting; Vote Required." Concurrently with the execution
of the Contour Merger Agreement, Sun entered into a Stockholder Stock Option and
Proxy Agreement (the "Contour Stock Option Agreement") with RCA, pursuant to
which RCA agreed to vote, and granted to Sun an irrevocable proxy to vote, all
of the 5,222,003 shares of Contour Common Stock and 85,000 shares of Contour
Preferred Stock owned by RCA in favor of the Contour Merger Agreement and the
Contour Merger. See "The Contour Stockholder Stock Option and Proxy Agreement."
AS A RESULT, SUN HAS THE RIGHT TO VOTE AT THE CONTOUR SPECIAL MEETING SUFFICIENT
SHARES TO APPROVE THE CONTOUR MERGER AGREEMENT WITHOUT THE AFFIRMATIVE VOTE OF
ANY OTHER STOCKHOLDER, THEREBY ASSURING THE APPROVAL OF THE CONTOUR MERGER
AGREEMENT AND THE CONTOUR MERGER.
 
    Shares of Contour Capital Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the Contour Special Meeting will be treated as being present at
such meeting for purposes of establishing a quorum and will also be treated as
votes eligible to be cast by the Contour Capital Stock present in person at the
Contour Special Meeting and entitled to vote on the subject matter. Abstentions
will be counted for purposes of determining both the presence or absence of a
quorum for the transaction of business and the total number of votes cast with
respect to a particular matter. Abstentions will have the same effect as a vote
against the approval of the Contour Merger Agreement and the Contour Merger,
which approval will require the affirmative vote of a majority of the
outstanding shares of Contour Capital Stock (with the Contour Preferred Stock
voting on an as-converted basis), voting together as a single class.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the Contour Record Date, directors and executive officers
of Contour and their respective affiliates, including RCA, may be deemed to be
the beneficial owners of shares of Contour Capital Stock representing
approximately 66.7 percent of the outstanding voting power of Contour. Each of
the directors and executive officers of Contour has indicated that such person
intends to vote or direct the vote of all the shares of Contour Capital Stock
over which such person has voting control in favor of the Contour Merger
Agreement and the Contour Merger. In addition, concurrently with the execution
of the Contour Merger Agreement, Sun and RCA entered into the Contour Stock
Option Agreement, pursuant to which RCA granted to Sun the right to vote all of
the 5,222,003 shares of Contour Common Stock and 85,000 shares of Contour
Preferred Stock owned by RCA in favor of the Contour Merger Agreement and the
Contour Merger. See "The Contour Stockholder Stock Option and Proxy Agreement."
As a result, Sun has the right to vote at the Contour Special Meeting sufficient
shares to approve the Contour Merger Agreement without the affirmative vote of
any other stockholder, thereby assuring the approval of the Contour Merger
Agreement and the Contour Merger.
 
    STOCKHOLDERS OF CONTOUR ARE NOT BEING ASKED FOR A PROXY AND ARE REQUESTED
NOT TO SEND A PROXY.

RECOMMENDATION OF RCA'S BOARD OF DIRECTORS
 
    THE BOARD OF DIRECTORS OF RCA HAS UNANIMOUSLY APPROVED AND ADOPTED THE RCA
MERGER AGREEMENT AND APPROVED THE RCA MERGER, AND UNANIMOUSLY RECOMMENDS THAT
THE SHAREHOLDERS OF RCA VOTE FOR THE APPROVAL AND ADOPTION OF THE RCA MERGER
AGREEMENT AND APPROVAL OF THE RCA MERGER. Shareholders of RCA, in evaluating
whether to approve and adopt the RCA Merger Agreement and approve the RCA
Merger, should consider the fact that the board of directors of RCA did not
engage a financial advisor or obtain a fairness opinion in connection with its
decision to make such recommendation. See "Risk Factors--Risk Factors Concerning
the Mergers--Lack of a Fairness Opinion in Connection with the RCA Merger" and
"The RCA Merger--RCA's Reasons for the RCA Merger; Recommendation of RCA's Board
of Directors."
 
RECOMMENDATION OF CONTOUR'S BOARD OF DIRECTORS
 
    THE BOARD OF DIRECTORS OF CONTOUR HAS UNANIMOUSLY APPROVED AND ADOPTED THE
CONTOUR MERGER AGREEMENT AND APPROVED THE CONTOUR MERGER, AND UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF CONTOUR VOTE FOR THE APPROVAL AND ADOPTION
OF THE CONTOUR MERGER AGREEMENT AND APPROVAL OF THE CONTOUR MERGER. See "The
Contour Merger--Contour's Reasons for the Contour Merger; Recommendation of
Contour's Board of Directors."
 
OPINIONS OF SUN'S FINANCIAL ADVISOR
 
    In making its recommendation with respect to the RCA Merger, the board of
directors of Sun considered, among other things, the oral opinion, dated
November 24, 1997 (which was later confirmed in writing), of J.P. Morgan
Securities Inc. ("J.P. Morgan"), Sun's financial advisor, to the effect that,
based upon and subject to the various assumptions and considerations set forth
in such opinion, as of the date of such opinion, the consideration to be paid by
Sun in the RCA Merger was fair, from a financial point of view, to Sun. In
making its recommendation with respect to the Contour Merger, the board of
directors of Sun considered, among other things, the written opinion, dated
February 17, 1997, the date of the Contour Merger Agreement, of J.P. Morgan to
the effect that, based upon and subject to the various assumptions and
considerations set forth in such opinion, as of the date of such opinion, the
consideration to be paid by Sun in the Contour Merger was fair, from a financial
point of view, to Sun. A copy of J.P. Morgan's opinion letter dated November 24,
1997 with respect to the RCA Merger is attached to this Joint Proxy Statement/
Prospectus/Information Statement as Appendix B. A copy of J.P. Morgan's opinion
letter dated February 17, 1997 with respect to the Contour Merger is attached to
this Joint Proxy Statement/Prospectus/ Information Statement as Appendix E. J.P.
Morgan's opinion letters, which set forth the assumptions made, procedures
followed and matters considered by J.P. Morgan, and the scope of J.P. Morgan's
reviews, should be read carefully in their entirety. See "The RCA
Merger--Opinion of Sun's Financial Advisor" and "The Contour Merger--Opinion of
Sun's Financial Advisor."

    For services rendered in connection with and including the delivery of its
opinions on the RCA Merger, Sun paid J.P. Morgan an engagement fee of $250,000
upon execution of the engagement letter dated February 6, 1997, as amended April
3, 1998, and has agreed to pay J.P. Morgan a fee of $1,850,000 (including the
$250,000 engagement fee) payable upon consummation of the RCA Merger. J.P.
Morgan will not receive any additional compensation in connection with the
Contour Merger.
 
LACK OF FINANCIAL ADVISOR TO RCA
 
    The board of directors of RCA did not engage a financial advisor or obtain a
fairness opinion in connection with its decision to recommend that the
shareholders of RCA approve and adopt the RCA Merger Agreement and approve the
RCA Merger. See "Risk Factors--Risk Factors Concerning the Mergers--Lack of a
Fairness Opinion in Connection with the RCA Merger" and "The RCA Merger-- RCA's
Reasons for the RCA Merger; Recommendation of RCA's Board of Directors."
 
OPINION OF CONTOUR'S FINANCIAL ADVISOR
 
    Sterne, Agee & Leach, Inc. ("SALI"), Contour's financial advisor, has
rendered a written opinion dated as of April 8, 1997, to the effect that, as of
such date and based upon and subject to the assumptions, limitations and
qualifications set forth in such opinion, the consideration to be paid by Sun in
the Contour Merger was fair, from a financial point of view, to the holders of
Contour Common Stock. A copy of SALI's opinion is attached to this Joint Proxy
Statement/Prospectus/Information Statement as Appendix F. SALI's opinion, which
sets forth the assumptions made, procedures followed and other matters
considered by SALI, and the limits of SALI's review, should be read carefully in
its entirety. For services rendered in connection with and including the
delivery of its opinion on the Contour Merger, Contour has agreed to pay SALI a
fee of $100,000. The fee includes a $25,000 retainer and a $75,000 payment upon
the filing of this Joint Proxy Statment/Prospectus/Information Statement with
the Commission. See "The Contour Merger--Opinion of Contour's Financial
Advisor."
 
THE RCA MERGER
 
    EFFECTIVE TIME OF THE RCA MERGER
 
    As promptly as practicable after the satisfaction or waiver of the
conditions set forth in the RCA Merger Agreement, the parties thereto will file
a certificate of merger with the Secretary of State of the State of Colorado.
The RCA Merger will become effective upon such filing. See "The RCA Merger
Agreement--RCA Effective Time."
 
    CONDITIONS TO THE RCA MERGER
 
    Consummation of the RCA Merger is subject to the satisfaction of certain
conditions, including, without limitation, (i) the approval and adoption of the
RCA Merger Agreement and the approval of the RCA Merger by the requisite vote of
the stockholders of Sun and the shareholders of RCA; (ii) the absence of any
restrictive court orders or any other legal restraints or prohibitions
preventing or making illegal the consummation of the RCA Merger; and (iii) the
receipt by Sun and RCA of certain opinions regarding tax and accounting matters.
The consummation of the Contour Merger is not a condition to the RCA Merger. See
"The RCA Merger Agreement--Conditions to the RCA Merger."
 
    TERMINATION
 
    The RCA Merger Agreement may be terminated and the RCA Merger may be
abandoned prior to the RCA Effective Time notwithstanding approval by the
stockholders of Sun and/or the shareholders of RCA under the circumstances
specified in the RCA Merger Agreement, including by mutual written agreement of
Sun and RCA and termination by either party if the RCA Merger is not consummated
by June 30, 1998. See "The RCA Merger Agreement--Termination." Neither Sun nor
RCA has the right to
 
                                       23
<PAGE>
terminate the RCA Merger Agreement and abandon the RCA Merger based on the
market price of the Sun Common Stock.
 
    REGULATORY MATTERS
 
    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"), and the rules promulgated thereunder, the RCA Merger may not be
consummated until notifications have been given and certain information has been
furnished to the Federal Trade Commission (the "FTC") and the Antitrust Division
of the United States Justice Department (the "Antitrust Division"), and
specified waiting period requirements have been satisfied. The waiting period
first applicable to the RCA Merger under the HSR Act was terminated early and
thus expired on May 16, 1997. However, Sun's and RCA's first HSR notices expired
on May 16, 1998. Sun and RCA each filed additional HSR notices for which the
waiting period expired on May 20, 1998. See "The RCA Merger--Regulatory
Matters."
 
    In addition, Sun and RCA are required to file notices with, and in some
jurisdictions obtain approvals or consents from, various state agencies
responsible for the licensure or certification of healthcare facilities in
states where Sun or RCA conduct their respective businesses.
 
    DISSENTERS' RIGHTS
 
    Holders of RCA Series AA Preferred Stock and RCA Series F Preferred Stock
who do not vote such shares in favor of the RCA Merger may be entitled to
certain dissenters' rights under Colorado law. Holders of RCA Common Stock do
not have dissenters' rights under Colorado law. See "The RCA Merger--Dissenters'
Rights."
 
    INTERESTS OF CERTAIN PERSONS IN THE RCA MERGER
 
    In considering the recommendation of the board of directors of RCA with
respect to the RCA Merger Agreement and the transactions contemplated thereby,
shareholders should be aware that certain members of the management of RCA and
the board of directors of RCA have certain interests in the RCA Merger that are
in addition to the interests of shareholders of RCA in general. These interests
arise from, among other things, certain employment agreements and benefit plans,
settlement of certain outstanding litigation and indemnification arrangements
and certain other matters that Sun has agreed to assume after the RCA Merger.
 
    Pursuant to the terms of their respective employment agreements, if any of
Philip M. Rees, General Counsel of RCA, John R. Mack, Senior Vice President of a
subsidiary of RCA, or Jeffrey Andrews, President of a subsidiary of RCA, is
terminated by Sun other than for "cause" or any such officer terminates his
employment for "good reason" (as each such term is defined in the respective
officer's employment agreement), and subject to each such officer's compliance
with the terms of his employment agreement, then each such officer will have the
right thereafter to receive such officer's salary and benefits enumerated in
such officer's employment agreement for the remainder of the term. Under such
conditions, in the event of such termination, Mr. Rees would be entitled to
receive an annual salary of $200,000 until July 1, 1998, $225,000 until July 1,
1999, $247,500 until July 1, 2000, and, as a result of RCA's failure prior to
May 1, 1998 to notify Mr. Rees of the termination, contingent on consummation of
the RCA Merger, of his employment agreement, $272,250 until July 1, 2001,
immediately vested and exercisable nonqualified stock options to purchase 25,000
shares of RCA Common Stock during each year of the employment agreement, and
certain other benefits; Mr. Mack would be entitled to receive an annual salary
of $192,000 until June 30, 1998, and $212,000 until June 30, 1999, immediately
vested and exercisable nonqualified stock options to purchase 25,000 shares of
RCA Common Stock during each year of the employment agreement, and certain other
benefits; and Mr. Andrews would be entitled to receive an annual salary of
$180,000 until July 1, 1998, and $220,000 until July 1, 1999, immediately vested
and exercisable nonqualified stock options to purchase 50,000 shares of RCA
Common Stock during each year
 
                                       24
<PAGE>
of the employment agreement, and certain other benefits. Any stock option
granted pursuant to such employment agreements will expire five years from the
date of grant.
 
    Between August 25, 1997 and October 24, 1997, ten putative class action
lawsuits were filed in the United States District Court for the Northern
District of Georgia on behalf of persons who purchased RCA Common Stock, naming
RCA and certain of its officers and directors as defendants. On November 25,
1997, RCA, Sun and representatives of the plaintiffs entered into a memorandum
of understanding, pursuant to which Sun has agreed to pay $9 million into an
interest-bearing escrow account maintained by Sun to settle these actions. See
"Risk Factors--Risk Factors Concerning RCA and Contour--Shareholder Litigation"
and "The RCA Merger--Background of the Mergers." In addition, pursuant to the
RCA Merger Agreement Sun has agreed to provide indemnification to RCA's officers
and directors under certain circumstances. See "The RCA Merger--Interests of
Certain Persons in the RCA Merger" and "The RCA Merger Agreement--Directors' and
Officers' Indemnification."
 
    As of May 1, 1997, directors and executive officers of RCA beneficially
owned (i) 4,910,321 shares of RCA Common Stock for which they will receive the
same consideration as other RCA shareholders and (ii) unexercised options to
acquire 1,099,152 shares of RCA Common Stock, which will be treated as described
below under "The RCA Merger--Interests of Certain Persons in the RCA Merger." In
addition, employees (or former employees) of RCA held unexercised options to
purchase an aggregate of 1,437,171 shares of RCA Common Stock at a weighted
average exercise price of $6.77 per share (at exercise prices ranging from
$4.647 to $15.95 per share). See "The RCA Merger--Interests of Certain Persons
in the RCA Merger."
 
    ACCOUNTING TREATMENT
 
    Both Sun and RCA believe that the RCA Merger will qualify as a pooling of
interests for accounting and financial reporting purposes. Consummation of the
RCA Merger is conditioned upon the receipt by each of Sun and RCA of a letter
from Arthur Andersen LLP, independent public accountants of Sun, stating that
the RCA Merger, in its opinion, will qualify for pooling of interests accounting
treatment. See "The RCA Merger--Accounting Treatment" and "The RCA Merger
Agreement--Conditions to the RCA Merger."
 
    FEES AND EXPENSES
 
    Under certain circumstances, either Sun or RCA may be required to pay a
termination fee and to reimburse the other party for its reasonable
out-of-pocket expenses if the RCA Merger Agreement is terminated. See "The RCA
Merger Agreement--Termination Fees and Expenses."
 
    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The RCA Merger will qualify as a tax-free reorganization under Section 368
of the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly,
holders of RCA Capital Stock will not recognize gain or loss for federal income
tax purposes by reason of the conversion of RCA Capital Stock into Sun Common
Stock, except for cash received in lieu of fractional shares. It is a condition
to Sun's and RCA's obligations to consummate the RCA Merger that each shall have
received opinions from its respective tax counsel, which opinions shall not have
been withdrawn or modified in any material respect, to the effect that the
Merger will qualify as a tax-free reorganization under Section 368 of the Code,
and that each of Sun, RCA Merger Sub and RCA will be a party to the
reorganization within the meaning of Section 368(b) of the Code. The RCA Merger
will not have any tax consequences to Sun stockholders. See "The RCA
Merger--Certain Federal Income Tax Consequences."
 
                                       25
<PAGE>
    EXCHANGE OF SHARE CERTIFICATES
 
    If the RCA Merger becomes effective, Sun will mail a letter of transmittal
with instructions to all holders of record of RCA Capital Stock as of the RCA
Effective Time for use in surrendering their stock certificates in exchange for
certificates representing Sun Common Stock and a cash payment in lieu of
fractional shares. CERTIFICATES SHOULD NOT BE SURRENDERED UNTIL THE LETTER OF
TRANSMITTAL IS RECEIVED. See "The RCA Merger--Exchange of Shares."
 
    OPERATIONS FOLLOWING THE RCA MERGER
 
    Sun plans to integrate promptly the operations, facilities and personnel of
Sun and RCA following the RCA Merger. The general result will be to combine
administrative organizations with a reduced headcount and overhead structure and
to eliminate duplicative or unnecessary corporate functions. Sun will assume
management of all RCA operations upon completion of the RCA Merger. None of the
directors or executive officers of RCA is expected to continue in the management
of the combined operations. Sun expects to incur a charge of approximately $30
million in connection with the Mergers, consisting of transaction costs and
integration expenses, including elimination of redundant corporate functions,
severance costs related to headcount reductions, the write-off of certain
intangibles and property and equipment and the settlement of certain class
action lawsuits. In addition, there can be no assurance that Sun will not incur
additional charges in subsequent quarters to reflect costs associated with the
Mergers. See "Risk Factors--Risk Factors Concerning the Mergers--Difficulty of
Integrating Acquired Operations," "The RCA Merger--Operations Following the RCA
Merger" and "Unaudited Pro Forma Combined Financial Statements."
 
    AMENDMENTS TO THE RCA MERGER AGREEMENT
 
    On May 27, 1997, the RCA Merger Agreement was amended by Amendment No.1
thereto, which (i) eliminated a provision in the RCA Merger Agreement that
granted to Christopher F. Brogdon, Connie Brogdon, Edward E. Lane, Darrell C.
Tucker and Winter Haven Homes, Inc. an option to purchase the shares of In-House
Rehab Corporation (formerly known as Perennial Development Corporation) ("In-
House") owned by RCA; (ii) prohibited Sun from selling the shares of In-House
owned by RCA, subject to certain exceptions, or acquiring additional shares of
capital stock of In-House, for a period of 24 months following the RCA Effective
Time and required Sun to vote such shares for the election of director
candidates with In-House's management; (iii) increased the original RCA common
exchange ratio of 0.6625 shares of Sun Common Stock for each share of RCA Common
Stock to the first amended RCA common exchange ratio of 0.68265 shares of Sun
Common Stock for each share of RCA Common Stock; and (iv) added to the RCA
Merger Agreement additional representations and warranties and covenants related
to the accounts receivable and accounts payable of RCA.
 
    On August 21, 1997 the RCA Merger Agreement was amended by Amendment No.2
thereto, which (i) decreased the first amended RCA common exchange ratio from
0.68265 shares of Sun Common Stock for each share of RCA Common Stock to the
second amended RCA common exchange of 0.520 shares of Sun Common Stock for each
share of RCA Common Stock; (ii) contained certain provisions requiring RCA to
revise and restate its fiscal 1997 financial statements; (iii) waived certain
representations and warranties which had become incorrect since the date of the
RCA Merger Agreement and quantified the materiality threshold applicable to the
defined term "Company Material Adverse Effect"; (iv) contained certain
provisions relating to the resignation of RCA's independent auditors; (v)
amended the provisions of the RCA Merger Agreement related to indemnification of
RCA's officers and directors; and (vi) extended the date after which either
party may freely terminate the RCA Merger Agreement from September 30, 1997 to
November 30, 1997 (or, under certain circumstances, to December 31, 1997).
 
    On November 25, 1997, the RCA Merger Agreement was amended by Amendment No.3
thereto, which (i) decreased the second amended RCA common exchange ratio from
0.520 shares of Sun Common
 
                                       26
<PAGE>
Stock for each share of RCA Common Stock to the RCA Common Exchange Ratio; (ii)
waived certain representations and warranties which had become incorrect since
the date of the RCA Merger Agreement; (iii) modified the definition of "Company
Material Adverse Effect" to relate only to changes in the assets or liabilities
of RCA; (iv) contained provisions relating to Sun and its affiliates providing
ancillary services to RCA and its affiliates; (v) contained provisions allowing
RCA to obtain up to $15 million in working capital financing under certain
conditions; (vi) contained provisions relating to certain related company
leases; (vii) modified the conditions to Sun's obligations to consummate the RCA
Merger related to RCA's representations and warranties and made corresponding
modifications in Sun's termination rights; (viii) provided for a termination fee
payable to RCA in the event Sun's board of directors changes its recommendation
of the RCA Merger in a manner adverse to RCA; (ix) contained certain other
technical provisions; and (x) extended the date after which either party may
freely terminate the RCA Merger Agreement to March 31, 1998.
 
    On April 3, 1998, the RCA Merger Agreement was amended by Amendment No. 4
thereto, which (i) added as a condition to Sun's obligation to consummate the
RCA Merger a requirement that the Memorandum of Understanding entered into in
connection with the settlement of certain shareholder litigation involving RCA
remain in effect (see "Risk Factors--Risks Concerning RCA and Contour--
Shareholder Litigation"); and (ii) extended the date after which either party
may freely terminate the RCA Merger Agreement from March 31, 1998 to June 30,
1998. See "The RCA Merger--Background of the Mergers" and "The RCA Merger
Agreement--Amendments to the RCA Merger Agreement."
 
    RCA STOCKHOLDERS' STOCK OPTION AND PROXY AGREEMENT
 
    Concurrent with the execution of the RCA Merger Agreement and as an
inducement to Sun to enter into the RCA Merger Agreement, Sun and Christopher F.
Brogdon, Connie B. Brogdon, Edward E. Lane, Darrell C. Tucker and Winter Haven
Homes, Inc. (each a "Stockholder") entered into a Stockholders Stock Option and
Proxy Agreement, dated as of February 17, 1997, as amended by Amendment No. 1
thereto dated as of November 25, 1997, pursuant to which each Stockholder
granted to Sun an option to purchase each Stockholder's shares of RCA Capital
Stock, representing approximately 36 percent of the shares of the RCA Capital
Stock issued and outstanding on the date of grant, at a purchase price of $10.00
per share of RCA Common Stock and RCA Series F Preferred Stock and $10.00 per
share of RCA Series AA Preferred Stock (the "RCA Stock Option Agreement"). On
June 4, 1997, Ms. Brogdon sold 101,871 shares of RCA Common Stock (representing
approximately two percent of the shares of RCA Capital Stock subject to the
option) in apparent violation of the RCA Stock Option Agreement. According to
documents filed by Ms. Brogdon with the Commission in connection with such sale,
such shares were sold pursuant to Rule 144 of the Securities Act at a price of
$10.0023 per share. Sun has not yet determined what action, if any, it will take
in response to such transaction. See "The RCA Stockholders' Stock Option and
Proxy Agreement."
 
THE CONTOUR MERGER
 
    EFFECTIVE TIME OF THE CONTOUR MERGER
 
    As promptly as practicable after the satisfaction or waiver of the
conditions set forth in the Contour Merger Agreement, the parties thereto will
file a certificate of merger with the Secretary of State of the State of Nevada.
The Contour Merger will become effective upon such filing. See "The Contour
Merger Agreement--Contour Effective Time."
 
    CONDITIONS TO THE CONTOUR MERGER
 
    Consummation of the Contour Merger is subject to the satisfaction of certain
conditions, including, without limitation, (i) the approval and adoption of the
Contour Merger Agreement and the approval of the Contour Merger by the requisite
vote of the stockholders of both Sun and Contour; (ii) the absence of
 
                                       27
<PAGE>
any restrictive court orders or any other legal restraints or prohibitions
preventing or making illegal the consummation of the Contour Merger; and (iii)
the continuing accuracy of the representations and warranties made in the
Contour Merger Agreement at and as of the Contour Effective Time. The
consummation of the RCA Merger is not a condition to the Contour Merger. See
"The Contour Merger Agreement--Conditions to the Contour Merger."
 
    TERMINATION
 
    The Contour Merger Agreement may be terminated and the Contour Merger may be
abandoned prior to the Contour Effective Time notwithstanding approval by the
stockholders of Sun and/or Contour under the circumstances specified in the
Contour Merger Agreement, including by mutual written agreement of Sun and
Contour and termination by either party if the Contour Merger is not consummated
by June 30, 1998. See "The Contour Merger Agreement--Termination." Neither Sun
nor Contour has the right to terminate the Contour Merger Agreement and abandon
the Contour Merger based on the market price of the Sun Common Stock.
 
    REGULATORY MATTERS
 
    Other than the filing with respect to the RCA Merger, no separate filing is
required under the HSR Act, and no other filing with or approval of any federal
or state governmental entity is required in connection with the Contour Merger.
 
    DISSENTERS' RIGHTS
 
    Stockholders of Contour who do not vote their shares in favor of the Contour
Merger may be entitled to certain dissenters' rights under Nevada law. See "The
Contour Merger--Dissenters' Rights."
 
    INTERESTS OF CERTAIN PERSONS IN THE CONTOUR MERGER
 
    In considering the recommendation of the board of directors of Contour with
respect to the RCA Merger Agreement and the transactions contemplated thereby,
stockholders should be aware that certain members of the management of Contour
and the board of directors of Contour have certain interests in the Contour
Merger that are in addition to the interests of stockholders of Contour in
general. These interests arise from, among other things, certain benefit plans
and indemnification arrangements which Sun has agreed to assume after the
Contour Merger.
 
    Not including 5,440,878 shares of Contour Common Stock beneficially held by
RCA, as of May 1, 1998, directors and executive officers of Contour beneficially
owned (i) 164,577 shares of Contour Common Stock for which they will receive the
same consideration as other Contour stockholders, (ii) unexercised options to
acquire 344,250 shares of Contour Common Stock, and (iii) fully vested,
unexercised warrants to acquire 52,500 shares of Contour Common Stock at an
exercise price equal to $3.00 per share prior to June 30, 1999, which will be
treated as described below under "The Contour Merger--Interests of Certain
Persons in the Contour Merger." In addition, employees (or former employees) of
Contour held unexercised options to purchase an aggregate of 654,250 shares of
Contour Common Stock at a weighted average exercise price of $3.63 per share (at
exercise prices ranging from $1.905 to $5.50 per share). See "The Contour
Merger--Interests of Certain Persons in the Contour Merger."
 
    ACCOUNTING TREATMENT
 
    If the shareholders of RCA approve the proposed RCA Merger, the acquisition
of the interest in Contour not owned by RCA is expected to be accounted for as a
purchase. If the shareholders of RCA do not approve the proposed RCA Merger, the
acquisition of all of Contour is expected to be accounted for as a purchase. See
"The Contour Merger--Accounting Treatment."
 
                                       28
<PAGE>
    FEES AND EXPENSES
 
    Under certain circumstances, either Sun or Contour may be required to pay a
termination fee and to reimburse the other party for its reasonable
out-of-pocket expenses if the Contour Merger Agreement is terminated. See "The
Contour Merger Agreement--Termination Fees and Expenses."
 
    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The tax treatment of the Contour Merger to the holders of Contour Capital
Stock is uncertain. HOLDERS OF CONTOUR CAPITAL STOCK ARE STRONGLY URGED TO
CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN
TAX CONSEQUENCES OF THE CONTOUR MERGER. Shearman & Sterling will deliver to Sun
an opinion to the effect that assuming the RCA Merger occurs promptly after
consummation of the Contour Merger, the Contour Merger would more likely than
not qualify as a tax-free reorganization. In such a case, the holders of Contour
Capital Stock will not recognize gain or loss for federal income tax purposes on
the conversion of Contour Capital Stock into Sun Common Stock, except for cash
received in lieu of fractional shares. Alternatively, if the Contour Merger does
not qualify as a tax-free reorganization, the holders of Contour Capital Stock
will recognize gain or loss for federal income tax purposes on the conversion of
Contour Capital Stock into Sun Common Stock. See "The Contour Merger--Certain
Federal Income Tax Consequences."
 
    EXCHANGE OF SHARE CERTIFICATES
 
    If the Contour Merger becomes effective, Sun will mail a letter of
transmittal with instructions to all holders of record of Contour Capital Stock
as of the Contour Effective Time for use in surrendering their stock
certificates in exchange for certificates representing Sun Common Stock and a
cash payment in lieu of fractional shares. CERTIFICATES SHOULD NOT BE
SURRENDERED UNTIL THE LETTER OF TRANSMITTAL IS RECEIVED. See "The Contour
Merger--Exchange of Shares."
 
    OPERATIONS FOLLOWING THE CONTOUR MERGER
 
    Following the Contour Merger, Contour will be managed by the same executive
officers and will continue its operations substantially as such operations were
conducted prior to the Contour Merger. See "The Contour Merger--Operations
Following the Contour Merger."
 
    AMENDMENTS TO THE CONTOUR MERGER AGREEMENT
 
    On August 21, 1997, the Contour Merger Agreement was amended by Amendment
No. 1 thereto, which extended the date after which either party could freely
terminate the Contour Merger Agreement from September 30, 1997 to November 30,
1997 (or, under certain circumstances, to December 31, 1997).
 
    On November 25, 1997, the Contour Merger Agreement was amended by Amendment
No. 2 thereto, which extended the date after which either party may freely
terminate the Contour Merger Agreement to March 31, 1998 and contained certain
other technical provisions.
 
    On April 3, 1998, the Contour Merger Agreement was amended by Amendment No.
3 thereto, which extended the date after which either party may freely terminate
the Contour Merger Agreement from March 31, 1998 to June 30, 1998. See "The RCA
Merger--Background of the Mergers" and "The Contour Merger Agreement--Amendments
to the Contour Merger Agreement."
 
    CONTOUR STOCKHOLDER STOCK OPTION AND PROXY AGREEMENT
 
    Concurrent with the execution of the Contour Merger Agreement and as an
inducement to Sun to enter into the Contour Merger Agreement, Sun and RCA
entered into the Contour Stock Option Agreement, pursuant to which RCA granted
to Sun an option to purchase shares of Contour Capital Stock, representing
approximately 65% of the shares of the Contour Capital Stock issued and
outstanding
 
                                       29
<PAGE>
on the date of grant, at a purchase price of $8.50 per share of Contour Common
Stock and $4.00 per share of Contour Preferred Stock. See "The Contour

    On May 4, 1998, Sun completed a private placement of $125.0 million ($150.0
million if the over-allotment option is exercised in full) aggregate principal
amount of its 9 3/8% Senior Subordinated Notes due 2008 (the "Debt Offering")
(having an aggregate liquidation amount of $345.0 million). Concurrently with
the Debt Offering, Sun Financing I, a statutory business trust formed under the
laws of the State of Delaware and a wholly-owned subsidiary of Sun, completed a
separate private placement of 13,800,000 shares of its 7% Convertible Trust
Issued Preferred Securities (liquidation amount $25 per share) having an
aggregate liquidation amount of $345.0 million, the proceeds of which were
loaned to Sun (the "Convertible Securities Offering" and, together with the Debt
Offering, the "Offerings"). A portion of the net proceeds from the Convertible
Securities Offering were used to repay approximately $300.0 million of
outstanding borrowings under the term loan portion of Sun's $1.2 billion credit
facility (the "Credit Facility"). The remaining net proceeds from the Offerings
were used to reduce outstanding borrowings under the revolving credit portion of
the Credit Facility, which amounts may be subsequently reborrowed.
 
    On or about January 23, 1996, two former stockholders of SunCare, John
Brennan and Susan Bird, filed a lawsuit (the "SunCare Litigation") against Sun
and certain of its officers and directors in the United States District Court
for the Southern District of Indiana. Plaintiffs allege, among other things,
that Sun did not disclose material facts concerning the investigation by the OIG
and that Sun's financial results were misstated. The complaints purport to state
claims, INTER ALIA, under Federal and state securities laws and for breach of
contract, including a breach of a registration rights agreement pursuant to
which Sun agreed to register the shares of Sun's common stock issued to such
former stockholders of SunCare in the acquisition. On May 21, 1998, Sun and the
plaintiffs reached an agreement in principle to settle the action for $7.4
million. The settlement is subject to the execution of definitive documentation.
The settlement of $7.4 million will be recorded by Sun as a pretax charge during
the second quarter of 1998.

Contour Merger accounted for as a purchase as if the Contour Merger had occurred

    - Sun and RCA Only presents item (3) for the years ended December 31, 1995
      and 1996.
 
    The selected Unaudited Pro Forma Combined Financial Statements should be
read in conjunction with the Unaudited Pro Forma Combined Financial Statements
and the notes thereto, which are included in this Joint Proxy
Statement/Prospectus/Information Statement. See "Unaudited Pro Forma Combined
Financial Statements." The Unaudited Pro Forma Combined Financial Statements are
based on the respective historical financial statements and the notes thereto of
Sun, Regency, RCA and Contour, which are included or incorporated by reference
in this Joint Proxy Statement/Prospectus/Information Statement. Sun and Regency
have a fiscal year end of December 31. RCA and Contour have a fiscal year end of
 
                                       33

June 30. RCA's and Contour's historical financial statements have been recast to
present their financial statements on a December 31 fiscal year-end for purposes
of combining with Sun in accordance with Article 11 of Regulation S-X. The
Unaudited Pro Forma Combined Financial Statements are presented for illustrative
purposes only and are not necessarily indicative of the operating results or
financial position that would have been achieved if the Regency Acquisition, the
RCA Merger and the Contour Merger had been consummated as of the beginning of
the periods presented, nor are they necessarily indicative of the future
operating results or financial position of Sun, RCA and Contour. The Unaudited
Pro Forma Combined Statements of Earnings do not reflect the integration costs
related to the Regency Acquisition, the RCA Merger and the Contour Merger or the
benefits or cost savings anticipated to result from the Regency Acquisition, the
RCA Merger and the Contour Merger.
 
    Costs to be incurred in connection with the RCA Merger and the Contour
Merger are expected to be significant and will be charged against earnings of
the combined company. The charge is currently estimated to be approximately $30
million, and is expected to consist of transaction costs and integration
expenses, including elimination of redundant corporate functions, severance
costs related to headcount reductions, the write-off of certain intangibles and
property and equipment and the settlement of certain class action lawsuits. See
"Risk Factors--Risk Factors Concerning RCA and Contour--Shareholder Litigation."
Approximately $25 million of the estimated charges are expected to be charged to
operations in the fiscal quarter in which the RCA Merger is consummated. The
remaining approximately $5 million of the estimated charges relating to the
integration expenses are expected to be expensed as incurred, as these costs are
expected to benefit future combined operations. Pursuant to the memorandum of
understanding entered into by RCA, Sun and representatives of the plaintiffs in
such class action lawsuits, Sun has agreed to pay $9 million into an
interest-bearing account to settle such lawsuits. The settlement will be
expensed upon resolution of the conditions to the memorandum of understanding
which is expected to occur in the quarter that the RCA Merger is consummated.
The estimated integration charges and settlement costs have not been reflected
in the Unaudited Pro Forma Combined Financial Statements. These amounts are
preliminary estimates only and are therefore subject to change. In addition,
there can be no assurance that Sun will not incur additional charges in
subsequent quarters to reflect costs associated with the RCA Merger and the
Contour Merger. The components of the charges are expected to be as follows:

- ------------------------------
(1) There was no provision for Federal or state income taxes in Sun's
    consolidated financial statements for certain entities that subsequently
    became subsidiaries of Sun that had elected S corporation status prior to
    becoming C corporations. Net earnings (loss) and net earnings (loss) per
    share for the years ended December 31, 1993, 1994 and 1995 reflect Federal
    and state income taxes that these entities would have been subject to and
    liable for as C corporations prior to each of the entities' terminations of
    their S corporation status.
(2) See Note 1(o) to Sun's Consolidated Financial Statements (incorporated by
    reference herein) for net earnings (loss) per share information. Also, net
    earnings per share data for the years ended December 31, 1993 is calculated
    based upon the number of shares of Sun Common Stock issued upon the
    formation of Sun Healthcare Group, Inc. on April 15, 1993, which placed
    under the control of a single corporation all of Sun's operations and the
    appropriate weighted average number of shares of Sun Common Stock for common
    stock transactions of Sun subsequent to Sun's preincorporation agreement
    dated as of April 13, 1993, and also include the appropriate weighted
    average number of shares of Sun Common Stock for common stock transactions
    of CareerStaff and SunCare for the years ended December 31, 1993, 1994 and
    1995.
(3) Results of the year ended December 31, 1994 included a charge of $2,275,000
    in connection with the repayment of an inducement fee to effect the
    conversion of $24,377,000 of Sun's 6 1/2% Convertible Subordinated
    Debentures.
(4) Results of the year ended December 31, 1995 include a charge of $3,256,000
    in connection with the payment of an inducement fee to effect the conversion
    in January 1995 of $39,449,000 of Sun's 6 1/2% Convertible Subordinated
    Debentures and an extraordinary charge of $3,413,000, net of the related tax
    benefit, in connection with the tender offer of Sun's 11 3/4% Senior
    Subordinated Notes. (See Note (6) to Sun's Consolidated Financial Statements
    (incorporated by reference herein)).
(5) Also included in results for the year ended December 31, 1995 is $5,800,000
    of transaction-related merger costs incurred in connection with the mergers
    of Sun with CareerStaff and SunCare (see Note (2) to Sun's Consolidated
    Financial Statements (incorporated by reference herein)), a $59,000,000
    impairment loss recorded by Sun that primarily relates to goodwill
    associated with six of the forty facilities acquired in the acquisition of
    The Mediplex Group, Inc. ("Mediplex") (see Note (1)(g)) to Sun's
    Consolidated Financial Statements (incorporated by reference herein)),
    $4,006,000 related to averting a strike and negotiating new contracts for
    certain unionized homes in Connecticut, and a charge of $5,505,000 related
    to monitoring and responding to the government investigations and legal fees
    resulting from the shareholder litigation. The charge does not contain any
    estimated amounts for settlement of the OIG investigation or remaining
    shareholder litigation matters.
(6) Results for the year ended December 31, 1996 include a $24,000,000 charge
    recognized by Sun to settle certain of the lawsuits brought by shareholders
    and, as a reduction of this settlement charge, $9,000,000 that was received
    from Sun's director and officer liability insurance carrier in connection
    with the settlement (see Note (14) to Sun's Consolidated Financial
    Statements (incorporated by reference herein)). In addition, in 1996 Sun
    recorded additional expenses of $4,250,000 related to monitoring and
    responding to the continuing investigation by the United States Department
    of Health and Human Services' Office of Inspector General ("OIG") and to
    responding to the remaining shareholder litigation related to the
    announcement of the OIG investigation. The charge does not contain any
    estimated amounts for settlement of the OIG investigation or remaining
    shareholder litigation matters.
(7) In 1994, the provision for losses on accounts receivable reflects the
    write-off of $23,446,000 million of receivables of Mediplex that existed at
    the time of its June 1994 acquisition by Sun. These receivables were
    impaired as of the fourth quarter of 1994 or earlier. In 1995, an additional
    $7,608,000 million of Mediplex accounts receivable were written off, of
    which $3,549,000 million represented accounts receivable existing at the
    date of acquisition. In 1996, Sun recorded an additional provision for
    losses on accounts receivable of $6,550,000 million related primarily to its
    Mediplex facilities (see "Management's Discussion and Analysis of Financial
    Condition and Results of Operations" included in Sun's Annual Report on Form
    10-K for the year ended December 31, 1997, incorporated by reference
    herein).
(8) Results for the year ended December 31, 1997 include a charge of $7.0
    million recognized by Sun in order to reduce the carrying value of the
    Canadian operations to fair value based on revised estimates of selling
    value and of costs to sell. In addition, in 1997, Sun recorded an
    extraordinary charge of $17.9 million, net of the related tax benefit, in
    connection with Sun's purchase of Regency's 12.25% Junior Subordinated Notes
    due 2003 and of Regency's 9.875% Senior Subordinated Notes due 2002 and an
    extraordinary charge of $2.1 million, net of the related tax benefit,
    related to the refinancing of Sun's credit facility.

                           COMPARATIVE PER SHARE DATA
 
    The following table sets forth certain historical per share data of Sun, RCA
and Contour, and combined per share data on an unaudited pro forma basis. The
combined per share data is presented in two different formats: (1) giving effect
to the Contour Merger only as a purchase of all of Contour, assuming that 0.4755
shares of Sun Common Stock are issued in exchange for each share of Contour
Common Stock based upon the closing price of Sun Common Stock on May 14, 1998 of
$17.875 per share; and (2) giving effect to the RCA Merger and the purchase of
the minority interest of Contour not owned by RCA assuming that 0.505 shares of
Sun Common Stock are issued in exchange for each share of RCA Common Stock based
upon the closing price of Sun Common Stock on May 14, 1998 and that 0.4755
shares of Sun Common Stock are issued in exchange for each share of Contour
Common Stock not owned by RCA based upon the closing price of Sun Common Stock
on May 14, 1998. In the event the RCA Merger is approved, Sun's purchase of
Contour's equity not owned by RCA will be accounted for by Sun as a purchase by
Sun of a minority interest and Sun and its wholly-owned subsidiaries will own
100% of the outstanding shares of Contour Common Stock once the RCA Merger is
completed. In the event the RCA Merger is not approved, the Contour Merger will
be accounted for by Sun as a purchase of 100% of the outstanding shares of
Contour Common Stock. The historical per share data of Sun presented below is
presented as of and for the fiscal years ended December 31, 1995, 1996 and 1997
and as of and for the three months ended March 31, 1998. RCA and Contour have
fiscal year ends of June 30. The historical per share data of RCA is presented
as of and for the fiscal years ended June 30, 1995, 1996 and 1997 and as of and
for the nine-month period ended March 31, 1998. The historical per share data of
Contour is presented as of and for the fiscal year ended June 30, 1997 and as of
and for the nine-month period ended March 31, 1998. The historical per share
data of Regency presented below is presented as of and for the fiscal year ended
December 31, 1996 and as of and for the nine-month period ended September 30,
1997. This data should be read in conjunction with the selected historical and
pro forma financial information, the unaudited pro forma combined financial
statements and the separate historical financial statements of Sun, Regency, RCA
and Contour and the notes thereto incorporated or included elsewhere in this
Joint Proxy Statement/Prospectus/Information Statement. The unaudited pro forma
per share data is not necessarily indicative of the operating results or
financial position that would have been achieved had the RCA Merger and/or the
Contour Merger and/or the Regency Acquisition been consummated as of or at the
beginning of the periods presented, nor is it necessarily indicative of the
future operating results of the combined company.

RISK FACTORS CONCERNING THE MERGERS
 
    DIFFICULTY OF INTEGRATING ACQUIRED OPERATIONS.
 
    Sun's growth strategy relies heavily on the acquisition of long-term and
subacute care facilities. In October 1997, Sun acquired Regency, its largest
acquisition to date. Acquisitions present problems of integrating the acquired
operations with existing operations, including the loss of key personnel and
institutional memory of the acquired business, difficulty in integrating
corporate, accounting, financial reporting and management information systems
and strain on existing levels of personnel to operate such acquired businesses.
In addition, certain assumptions regarding the financial condition of an
acquired business may later prove to be incorrect. For example, in connection
with Sun's acquisition of The Mediplex Group, Inc. ("Mediplex") in June 1994, a
significant percentage of Mediplex's receivables proved to be uncollectible,
which resulted in significant write-offs in Sun's 1994, 1995 and 1996 fiscal
years. In addition, Sun's net earnings for its 1995 and 1996 fiscal years were
adversely affected by an impairment loss to certain goodwill associated with the
acquisition of Mediplex and negative revenue adjustments resulting primarily
from changes in accounting estimates based on events occurring in 1996. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included in Sun's Annual Report on Form 10-K for the year ended
December 31, 1997 and Sun's Quarterly Report on Form 10-Q for the fiscal quarter
ended March 31, 1998, incorporated by reference herein. Sun's ability to manage
its growth effectively will require it to continue to improve its corporate
accounting, financial reporting and management information systems, and to
attract, train, motivate and manage its employees effectively. See "--Risk
Factors Concerning the Mergers--Management of Growth."
 
    The integration of operations of RCA and Contour following the RCA Merger
and/or the Contour Merger (either or both of such transactions being referred to
herein as the "Mergers") will require the dedication of management resources
that will detract attention from Sun's day-to-day business. The difficulties of
integration may be increased by the necessity of coordinating geographically
separated organizations, integrating personnel with disparate business
backgrounds and combining different corporate cultures. As part of the Mergers,
Sun is expected to seek to reduce expenses by eliminating duplicative or
unnecessary personnel, corporate functions and other expenses. There can be no
assurance that Sun will be able to reduce expenses in this fashion or that there
will not be high costs associated with such activities
 
                                       42
<PAGE>
or that there will not be other material adverse effects of such activities.
Such events could materially and adversely affect Sun's financial condition and
results of operations. There can be no assurance that Sun will be able to
successfully integrate acquired operations, including the operations of RCA and
Contour, or to successfully manage any growth; failure to do so effectively and
on a timely basis could have a material adverse effect upon Sun's financial
condition and results of operations.
 
    Costs to be incurred in connection with the Mergers are expected to be
significant and will be charged against earnings of the combined company. The
charge is currently estimated to be approximately $30 million, and is expected
to consist of transaction costs and integration expenses, including elimination
of redundant corporate functions, severance costs related to headcount
reductions, the write-off of certain intangibles and property and equipment and
the settlement of certain class action lawsuits. See "Risk Factors--Risk Factors
Concerning RCA and Contour--Shareholder Litigation." Approximately $25 million
of the estimated charges are expected to be charged to operations in the fiscal
quarter in which the RCA Merger is consummated. Approximately $5 million of the
estimated charges relating to the integration expenses are expected to be
expensed as incurred as these costs are expected to benefit future combined
operations. Pursuant to the memorandum of understanding entered into by RCA, Sun
and representatives of the plaintiffs in certain class action lawsuits, Sun has
agreed to pay $9 million into an interest bearing account to settle such
actions. The settlement will be expensed upon resolution of the conditions to
the memorandum of understanding. These amounts are preliminary estimates only
and are therefore subject to change. In addition, there can be no assurance that
Sun will not incur additional charges in subsequent quarters to reflect costs
associated with the Mergers. The components of the charges are expected to be as
follows:

    If Sun is unable to effectively integrate the operations of an acquired
entity with Sun's existing operations, Sun may elect to divest some or all of
the acquired operations. In the second quarter of 1996, Sun sold its ambulatory
surgery subsidiary. Sun's decision to sell its ambulatory surgery subsidiary was
influenced in part by the marketplace's resistance to the integration of
subacute care with ambulatory surgery. In addition, in February 1998 Sun
announced that it had recognized a $7 million loss in anticipation of the sale
and divestiture of its outpatient rehabilitation therapy clinics in Canada,
which were acquired as part of Sun's acquisition of Columbia Health Care Inc.,
in 1995. Sun currently anticipates also selling its outpatient rehabilitation
therapy clinics in the United States, which were primarily acquired as part of
Sun's acquisitions of Mediplex and Regency.
 
    LACK OF A FAIRNESS OPINION IN CONNECTION WITH THE RCA MERGER.
 
    The board of directors of RCA initially approved Amendment No. 2 to the RCA
Merger Agreement ("Amendment No. 2") subject to the receipt of a fairness
opinion with respect to the consideration payable to RCA's shareholders pursuant
to the revised terms of the RCA Merger. However, RCA's board subsequently
elected to proceed with the RCA Merger, as amended by Amendment No. 2, without
obtaining a fairness opinion. The board of directors of RCA also did not engage
an independent financial advisor or obtain a fairness opinion in connection with
its decision to recommend that RCA's shareholders approve and adopt the RCA
Merger Agreement, as amended by Amendment No. 3 thereto ("Amendment No. 3"), and
approve the RCA Merger. As a result, RCA's shareholders will vote on the RCA
Merger

Agreement and the RCA Merger without an opinion from an unaffiliated financial
advisor that the RCA Merger is fair, from a financial point of view, to the
shareholders of RCA.
 
    Among the factors discussed in "RCA's Reasons for the RCA Merger;
Recommendation of RCA's Board of Directors," RCA's board of directors considered
the following factors in determining to proceed with the RCA Merger without a
fairness opinion: (i) there had been no credible offer from any third party
expressing an interest in acquiring RCA since the initial announcement of the
RCA Merger and that, in light of (A) RCA's restatement of its earnings and the
resignation of its auditors, (B) the class action lawsuits referred to under
"--Risk Factors Concerning RCA and Contour--Shareholder Litigation," and (C)
RCA's operating loss of approximately $9.4 million for the fiscal year ended
June 30, 1997, it was unlikely that RCA would receive a higher offer from
another merger partner; (ii) the consideration to be paid to the RCA
shareholders in the RCA Merger represents a premium of approximately 42% over
the average trading price of the RCA Common Stock for the three-month period
immediately preceding December 9, 1996, the date on which speculation first
began in the press concerning the possibility that RCA might be acquired,
represents a valuation for the RCA Common Stock that could not be achieved as
quickly, if at all, if RCA were to remain an independent entity and represents a
premium of approximately 21% over the closing price of the RCA Common Stock on
the date of the execution of Amendment No. 3; (iii) despite the adverse
developments that had occurred since the date of Amendment No. 2 and the
decrease in the applicable exchange ratio, the market value of the consideration
to be paid to RCA's shareholders pursuant to Amendment No. 3, based on the
closing price of the Sun Common Stock as of the date of Amendment No. 3 (which
had risen significantly since the date of the RCA Merger Agreement) and the RCA
Common Exchange Ratio, was in excess of the market value of the consideration
that would have been paid to RCA's shareholders under the original terms of the
RCA Merger Agreement (which provided for an Original RCA Common Exchange Ratio
of 0.6625 shares of Sun Common Stock for each share of RCA Common Stock) based
on the closing price of the Sun Common Stock as of the date thereof; and (iv)
Amendment No. 3 contained several revisions to the RCA Merger Agreement that
provided RCA and its shareholders with greater certainty that the RCA Merger
would be consummated and reduced the risk of another renegotiation of the terms
thereof prior to March 31, 1998 (the date after which either party might have
freely terminated the RCA Merger Agreement). In view of the foregoing, RCA's
board of directors did not believe that obtaining a fairness opinion in
connection with the RCA Merger was necessary because it believed that it could
evaluate the RCA Merger and make a recommendation to RCA's shareholders with
respect to the RCA Merger without such an opinion. However, shareholders of RCA,
in evaluating whether to approve and adopt the RCA Merger Agreement and approve
the RCA Merger, should consider the fact that the board of directors of RCA did
not engage a financial advisor or obtain a fairness opinion in connection with
its decision to make such recommendation.
 
    ADVERSE EFFECTS OF FAILURE TO CONSUMMATE THE MERGERS.
 
    SUN.  Since the execution of the RCA Merger Agreement on February 17, 1997,
Sun has been providing, on an arm's-length basis, pharmacy products and
services, therapy and supplies ("Ancillary Services"), and other management
consulting and advisory services, to certain facilities owned, leased or managed
by RCA, its affiliates and affiliates of the shareholders of RCA party to the
RCA Stock Option Agreement (the "RCA Facilities"). In connection with Amendment
No. 3, RCA agreed to take all reasonable action, including terminating existing
contracts with other providers of Ancillary Services in accordance with the
terms thereof, to cause all remaining RCA Facilities to begin receiving all of
their required Ancillary Services from Sun or Sun's affiliates as soon as
practicable after November 25, 1997. See "The RCA Merger--Ancillary Services
Agreements." As of March 31, 1998, Sun was providing Ancillary Services to RCA
Facilities in six states. Revenues from the provision of such Ancillary
Services, and from the provision of such other Management Consulting and
Advising Services, to RCA Facilities totaled $11.0 million and $12.4 million, or
1.5% and 0.6% of Sun's net revenues, for the three months ended March 31, 1998
and for the year ended December 31, 1997, respectively, substantially all of
which remained unpaid as of March 31, 1998. Sun and RCA have also entered into a
management agreement on
 
                                       44
<PAGE>
an arm's-length basis, dated as of July 15, 1997 (the "Management Agreement"),
pursuant to which Sun has agreed to provide management, consulting and advisory
services with respect to all 16 RCA Facilities in Virginia and North Carolina.
As payment for providing such services, Sun is entitled to receive a monthly
management fee equal to seven percent of the gross revenues of such RCA
Facilities. See "The RCA Merger--Management Agreements." Sun's revenues under
the Management Agreement totaled $0.3 million and $1.4 million for the three
months ended March 31, 1998 and for the year ended December 31, 1997,
respectively, all of which remained unpaid as of December 31, 1997. In the event
the RCA Merger is not consummated there can be no assurance that RCA would not
seek other sources for the provision of such services, and Sun's potential
future revenues therefrom would terminate.
 
    In addition, RCA is indebted to Sun in the principal amount of $14,750,000,
plus accrued and unpaid interest of $1.3 million as of March 31, 1998, pursuant
to two loan agreements entered into between Sun and RCA (the "Loan Agreements").
Amounts outstanding under the Loan Agreements are secured by a second lien on
all of RCA's accounts receivable and are subordinate to certain other
outstanding indebtedness of RCA. See "The RCA Merger--Loan Agreements." In the
event that the RCA Merger is not consummated, Sun's ability to collect the
amounts owed by RCA to Sun for the provision of Ancillary Services, the
provision of other services, under the Management Agreement, and under the Loan
Agreements, which together totaled approximately $39.0 million as of March 31,
1998, could be impaired, particularly in light of the recent deterioration of
RCA's financial condition and results of operation in the periods subsequent to
the execution of the RCA Merger Agreement. See "Risk Factors Concerning RCA and
Contour--Deterioration of RCA's Recent Financial Condition; Noncompliance with
Certain Covenants; Delinquent Property Taxes." Failure to collect such amounts
could require significant charges in the period in which the RCA Merger is
terminated, and Sun's financial condition and results of operations may be
materially and adversely affected in the period in which such charges are taken.
In addition, the failure to consummate the RCA Merger would prevent Sun from
obtaining the potential benefits of the RCA Merger to Sun and its stockholders
as described under "The RCA Merger--Sun's Reasons for the RCA Merger;
Recommendation of Sun's Board of Directors."
 
    Since the execution of the Contour Merger Agreement on February 17, 1997,
Contour has been providing medical products and supplies to facilities owned,
leased or managed by Sun. For the nine months ended December 31, 1997, Contour's
revenues from the sale of such products and supplies to Sun totaled $2.7
million, or approximately 6.6% of Contour's net revenues. In addition, on
December 31, 1997 Sun purchased from a third party $5.0 million aggregate
principal amount of 9.00% Contour Convertible Debentures (the "Contour
Debentures"), which are convertible into 1,000,000 shares of Contour Common
Stock, for an aggregate purchase price of $8.4 million in cash. See "The Contour
Merger--Contour Convertible Debentures." In the event that the Contour Merger
were not consummated, the value of the Contour Debentures could be impaired,
particularly in light of the recent deterioration of Contour's financial
condition and results of operation in the periods subsequent to the execution of
the Contour Merger Agreement. See "--Risks Concerning RCA and
Contour--Deterioration of Contour's Recent Financial Condition; Non-Compliance
with Certain Covenants." In addition, the failure to consummate the Contour
Merger would prevent Sun from obtaining the potential benefits of the Contour
Merger to Sun and its stockholders as described under "The Contour Merger--Sun's
Reasons for the Contour Merger; Recommendation of Sun's Board of Directors."
 
    RCA.  RCA's financial condition and results of operations have deteriorated
in the periods subsequent to the execution of the RCA Merger Agreement on
February 17, 1997. See "--Risk Factors Concerning RCA and Contour--Deterioration
of RCA's Financial Condition; Noncompliance with Certain Covenants; Delinquent
Property Taxes." There can be no assurance that such deterioration would not
continue or accelerate in the event that the RCA Merger were not consummated.
 
    A memorandum of understanding has been entered into in connection with a
proposed settlement of certain putative class action lawsuits brought against
RCA and certain of its directors and officers alleging violations of Federal
securities laws which is contingent upon the closing of the RCA Merger. In the
event
 
                                       45
<PAGE>
that the RCA Merger does not close, or if the settlement is terminated for any
reason prior to the RCA Effective Time, then RCA intends to vigorously defend
these lawsuits, which may result in protracted litigation that may result in a
diversion of management and other resources of RCA. The payment of substantial
legal costs or damages, or the diversion of management and other resources,
could have a material adverse effect on RCA's business, financial condition or
results of operations. See "--Risk Factors Concerning RCA and
Contour--Shareholder Litigation."
 
    RCA is indebted to Sun in the principal amount of $14,750,000, plus accrued
and unpaid interest of $1.3 million as of March 31, 1998, pursuant to the Loan
Agreements. Amounts outstanding under the Loan Agreements are secured by a
second lien on all of RCA's accounts receivable and are subordinate to certain
other outstanding indebtedness of RCA. See "The RCA Merger--Loan Agreements." In
the event that the RCA Merger is not consummated, Sun may demand immediate
repayment of the amounts outstanding under the Loan Agreements on the 120th day
following the termination of the RCA Merger (or earlier upon the occurrence of
certain events of default that may permit Sun to accelerate the amounts
oustanding under the Loan Agreements prior to their stated maturity subject to
certain restrictions in favor of RCA's senior lenders). There can be no
assurance that, in the event of such demand, the assets of RCA would be
sufficient to repay such indebtedness. In addition, a default by RCA of its
repayment obligations under the Loan Agreements may result in a cross-default
and acceleration under some of RCA's other outstanding indebtedness. In
addition, the failure to consummate the RCA Merger would prevent RCA from
obtaining the potential benefits of the RCA Merger to RCA and its stockholders
as described under "The RCA Merger--RCA's Reasons for the RCA Merger;
Recommendation of RCA's Board of Directors."
 
    CONTOUR.  Since the execution of the Contour Merger Agreement on February
17, 1997. Contour has been providing medical products and supplies to facilities
owned, leased or managed by Sun. For the nine months ended March 31, 1998,
Contour's revenues from the sale of such products and supplies to Sun totaled
$2.7 million, or approximately 6.6% of Contour's net revenues. In the event that
the Contour Merger is not consummated, there can be no assurance that Sun would
not seek other sources for the provision of such products and supplies, and
Contour's potential future revenues therefrom would terminate. In addition, to
the extent that RCA's business and financial condition deteriorates because of
the failure to close the RCA Merger, Contour's business, financial condition and
results of operations would also be adversely impacted by virtue of Contour's
dependence on RCA and RCA's inability to continue its relationship with Contour
as it existed prior to the termination of the RCA Merger. As of March 31, 1998,
Contour had accounts receivable of $6.5 million. In the event that the Contour
Merger Agreement is not consummated, Contour's ability to convert these
receivables may be materially and adversely affected. See "--Risk Factors
Concerning RCA and Contour--Deterioration of RCA's Recent Financial Condition;
Noncompliance with Certain Covenants; Delinquent Property Taxes" and
"--Contour's Dependence on RCA." In addition, the failure to consummate the
Contour Merger would prevent Contour from obtaining the potential benefits of
the Contour Merger to Contour and its stockholders as described under "The
Contour Merger--Sun's Reasons for the RCA Merger; Recommendation of Sun's Board
of Directors."
 
    UNCERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE CONTOUR MERGER.
 
    The federal income tax consequences of the Contour Merger are uncertain.
Assuming that the RCA Merger and Sun's contribution of the Contour Capital Stock
acquired in the Contour Merger occur promptly after consummation of the Contour
Merger, the Contour Merger would more likely than not qualify as a tax-free
reorganization within the meaning of Section 368 of the Code. Alternatively, if
the RCA Merger and Sun's contribution of the Contour Capital Stock acquired in
the Contour Merger to the Surviving RCA Corporation do not occur promptly after
consummation of the Contour Merger, the Contour Merger most likely would not
qualify as a tax-free reorganization. Holders of Contour Capital Stock are
strongly urged to consult their own tax advisors regarding the federal, state
and local and foreign
 
                                       46
<PAGE>
tax consequences of the Contour Merger. See "The Contour Merger--Certain Federal
Income Tax Consequences."
 
    MANAGEMENT OF GROWTH.
 
    Sun's success will depend in part on its ability to manage the growth of its
operations. Any such growth is expected to place a significant strain on Sun's
managerial, operational and financial resources. Sun's ability to manage growth
effectively will require it to continue to improve its corporate accounting,
financial reporting, internal accounting systems and management information
systems, and to attract, train, motivate and manage its employees effectively.
These demands are expected to require further expenditures for the addition of
new management personnel and the development of additional expertise by existing
management personnel. There can be no assurance that Sun will be able to manage
effectively the expansion of its operations, that its systems, procedures or
controls will be adequate to support Sun's operations or that Sun's management
will be able to exploit opportunities for its services and products. An
inability to manage growth, if any, could have a material adverse effect on
Sun's business, results of operations, financial condition and cash flow.
 
RISK FACTORS CONCERNING SUN
 
    SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE DEBT.
 
    Sun has substantial indebtedness. As of March 31, 1998, Sun had on a
consolidated basis approximately $1.7 billion of indebtedness, including $1.1
billion of indebtedness under the Credit Facility, and approximately $640
million of stockholders' equity. In addition, if the RCA Merger and the Contour
Merger had been consummated as of March 31, 1998, Sun's consolidated long-term
debt (including current maturities) would have increased by approximately $259
million based on RCA's March 31, 1998 balance sheet and assuming Sun acquires
the remaining 35% of Contour for Sun Common Stock. As of March 31, 1998, after
giving pro forma effect to the Offerings and the application of the net proceeds
therefrom, but without giving effect to the consummation of the Mergers, Sun
would have had on a consolidated basis approximately $1.3 billion of
indebtedness and approximately $633 million of stockholders' equity, and after
giving pro forma effect to the consummation of the Mergers, Sun would have had
on a consolidated basis approximately $1.5 billion of indebtedness and
approximately $666.0 million of stockholders' equity. As of March 31, 1998,
after giving pro forma effect to the Offerings, Sun would have had the ability
to borrow approximately an additional $276.6 million under the Credit Facility.
 
    In addition, as of December 31, 1997, Sun's existing lease agreements
required aggregate annual payments for the years ending December 31, 1998, 1999,
2000, 2001, and 2002 of $122.9 million, $122.5 million, $121.5 million, $115.7
million and $113.3 million, respectively. In addition, as part of its growth
strategy Sun intends to incur significant additional lease obligations and
therefore expects its annual lease obligations over the next five fiscal years
will be significantly greater than the amounts set forth in the preceding
sentence.
 
    At March 31, 1998, Sun had outstanding commitments for construction and
development costs of approximately $22.7 million in the United States and
approximately L0.6 million (approximately $1.0 million as of March 31, 1998) in
the United Kingdom. Sun also expects to loan up to $47.0 million (of which
approximately $41.4 million had been funded as of March 31, 1998) for the
development, construction and operation of assisted living facilities. Any such
advances are expected to be funded by borrowings under the Credit Facility and
will be subject to certain conditions, including the approval of each project by
Sun. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources" included in Sun's Annual
Report on Form 10-K for the year ended December 31, 1997 and Sun's Quarterly
Report on Form 10-Q for the fiscal quarter ended March 31, 1998, incorporated by
reference herein.
 
    The degree to which Sun is leveraged could have important consequences to
holders of Sun Common Stock, including, but not limited to, the following: (i) a
substantial portion of Sun's cash flow from
 
                                       47
<PAGE>
operations will be required to be dedicated to debt service and will not be
available for other purposes, including acquisitions; (ii) Sun's ability to
obtain additional financing in the future could be limited; (iii) certain of
Sun's borrowings are at variable rates of interest, which could result in higher
interest expense in the event of increases in interest rates; and (iv) the
indentures with respect to the 9 1/2% Notes, the Credit Facility and the United
Kingdom revolving credit facilities generally contain financial and restrictive
covenants that limit the ability of Sun to, among other things, borrow
additional funds, dispose of assets or pay cash dividends. Failure by Sun to
comply with such covenants could result in an event of default which, if not
cured or waived, would have a material adverse effect on Sun. In addition, Sun's
future capital requirements will depend on many factors, including Sun's working
capital needs, the costs associated with the Mergers and in particular, the
timing and extent to which Sun implements its acquisition strategy. Accordingly,
Sun expects that it may raise additional equity or debt financing in the future.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations-- Liquidity and Capital Resources" included in Sun's Annual Report on
Form 10-K for the year ended December 31, 1997 and Sun's Quarterly Report on
Form 10-Q for the fiscal quarter ended March 31, 1998, incorporated by reference
herein.
 
    RISKS ASSOCIATED WITH THE DEVELOPMENT AND EXPANSION OF ANCILLARY SERVICES.
 
    A significant aspect of Sun's operating strategy is to expand its therapy,
temporary therapy staffing and pharmaceutical services and, in particular, to
offer these services to nonaffiliated facilities. Therapy, temporary therapy
staffing and pharmaceutical services provided to nonaffiliated facilities in the
United States, while representing 25%, 28%, 31% and 28% of Sun's revenues for
the three months ended March 31, 1998, and for the years ended December 31,
1995, 1996 and 1997, respectively, provided more than half of Sun's operating
profits for such periods. In addition, a substantial portion of Sun's
consolidated interest expense was attributable to Sun's long-term and subacute
care services and its foreign operations and not the ancillary services business
due to the capital intensive nature of these businesses and to related
acquisitions. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" included in Sun's Annual Report on Form 10-K for the
year ended December 31, 1997 and Sun's Quarterly Report on Form 10-Q for the
fiscal quarter ended March 31, 1998, incorporated by reference herein. As a
result of the Regency Acquisition and RCA Merger, the percentage of revenues
from services provided to nonaffiliated facilities is expected to decrease.
Regulatory changes, including a Prospective Payment System ("PPS"), are expected
to be made that affect reimbursement for these services, which could adversely
affect Sun's profitability. See "--Risk Factors Concerning Sun--Risks Related to
Prospective Payment System," "--Risk Factors Concerning Sun--Potential Reduction
of Reimbursement Rates from Third Party Payors and Possible Adverse Impact on
Future Operating Results" and "--Risk Factors Concerning Sun--Risk of Adverse
Effect of Future Healthcare Reform." From time to time the negative publicity
surrounding the government investigations of Sun has slowed Sun's success in
obtaining additional outside contracts in the rehabilitation therapy business,
which in the past has resulted in higher than required therapist staffing levels
and has affected the private pay enrollment in certain inpatient facilities. In
addition, if government investigations have a negative impact on the future
billing practices related to Sun's rehabilitation therapy subsidiary, the
profitability of the services provided by such subsidiary would be reduced from
current levels. See "--Risk Factors Concerning Sun--Investigations; Uncertain
Impact on Future Operating Results."
 
    RISK OF ADVERSE EFFECT OF FUTURE HEALTHCARE REFORM.
 
    In recent years, an increasing number of legislative proposals have been
introduced or proposed in Congress and in some state legislatures that would
effect major changes in the healthcare system, either nationally or at the state
level. Among the proposals under consideration are cost controls on hospitals,
changes in reimbursement by federal and state payors such as Medicare and
Medicaid, limitations on the ability of Sun to maintain or increase the level of
services it provides, insurance market reforms to increase the availability of
group health insurance to small businesses and the requirement that all
businesses offer
 
                                       48
<PAGE>
health insurance coverage to their employees. Some of the leading proposals
would extend temporary reductions in Medicare reimbursement imposed under
current law, impose additional cuts in Medicare reimbursement and substantially
restructure Medicaid. In the Balanced Budget Act of 1997 ("BBA"), Congress
amended the reimbursement provisions applicable to exempt hospital services,
skilled nursing, therapy and other ancillary services. See "--Risk Factors
Concerning Sun--Risks Related to Prospective Payment System." These changes
include, but are not limited to, reductions in capital reimbursement; reductions
in certain laboratory reimbursement; limitations on ancillary costs of skilled
nursing facilities; bundling of ancillary services into nursing home payments;
and imposition of a prospective payment system for skilled nursing facility
services and home health services. Additional changes may still be enacted,
which may include amendments similar to those imposed under the BBA as well as
the imposition of salary equivalency for occupational and speech therapy
services. It is not clear at this time when or whether any new proposals will be
adopted, or, if adopted, what effect, if any, such proposals would have on Sun's
business. There can be no assurance that future healthcare legislation or other
changes in the administration or interpretation of governmental healthcare
programs will not have a material adverse effect on Sun's financial condition or
results of operations. See "--Risk Factors Concerning Sun--Potential Reduction
of Reimbursement Rates from Third Party Payors and Possible Adverse Impact on
Future Operating Results," "--Risk Factors Concerning Sun--Risks Associated with
Reimbursement Process and Collectibility of Certain Accounts Receivable,"
"--Risk Factors Concerning Sun--Potential Liability for Reimbursements Paid to
Former Operators of Acquired Facilities" and "--Risk Factors Concerning
Sun--Risks Associated with Related Party Transactions."
 
    RISKS RELATED TO PROSPECTIVE PAYMENT SYSTEM.
 
    In the BBA, Congress passed numerous changes to the reimbursement policies
applicable to exempt hospital services, skilled nursing, therapy and other
ancillary services. The BBA provides for a phase-in of a PPS for skilled nursing
facilities over a four-year period, effective for Sun's facilities on January 1,
1999. Under PPS, Medicare will pay skilled nursing facilities a fixed fee per
patient day based on the acuity level of the patient to cover all post-hospital
extended care routine service costs (I.E., Medicare Part A patients), including
ancillary and capital related costs for beneficiaries receiving skilled
services. The per diem rate will also cover substantially all items and services
furnished during a covered stay for which reimbursement was formerly made
separately under Medicare. During the phase-in, payments will be based on a
blend of the facility's historical costs and a federally established per diem
rate. Interim final regulations, including the federal per diem rates, were
published on May 12, 1998. It is unclear what the impact of PPS will be on Sun.
There can be no assurance that the imposition of PPS will not have a material
adverse effect on the results of operations and financial condition of Sun.
 
    Sun's revenues from its inpatient facilities will be significantly affected
by the size of the federally established per diem rate. There can be no
assurance that the per diem rate will not be less than the amount Sun's
inpatient facilities currently receive for treating the patients currently in
its care. Moreover, since Sun treats a greater percentage of higher acuity
patients than many nursing homes, Sun may also be adversely impacted if the
federal per diem rates for higher acuity patients doesn't adequately compensate
Sun for the additional expenses and risks for caring for such patients. As a
result, there can be no assurance that Sun's financial condition and results of
operations will not be materially and adversely affected.
 
    Sun is responding to the implementation of PPS by establishing
SUNSOLUTION-REGISTERED TRADEMARK-, whereby Sun will offer to provide ancillary
services for a fixed fee to unaffiliated facilities. There can be no assurance
that there will be a market for the SUNSOLUTION products and services or whether
a change in the demand for Sun's services following the imposition of the PPS
will not adversely affect Sun's revenues. Even if SUNSOLUTION is successful, no
assurance can be given that the costs of providing the contracted-for services
will be less than the fixed fee received by Sun for such services. Given the
relative profitability of Sun's ancillary services there can be no assurance
that Sun's margins from nonaffiliated operations and ultimately Sun's results of
operations and financial condition will not be adversely affected.
 
                                       49
<PAGE>
    In addition, for all Medicare patients not receiving post-hospital extended
care services (i.e., Medicare Part B patients), effective July 1, 1998,
reimbursement for ancillary services, including rehabilitation therapy, medical
supplies, pharmacy, temporary staffing for rehabilitation therapy, and other
ancillary services, will be made pursuant to yet-to-be-developed fee schedules.
In addition, effective January 1, 1999, there will be an annual per beneficiary
cap of $1,500 on reimbursement for outpatient physical therapy and speech
therapy and an annual per beneficiary cap of $1,500 on reimbursement for
occupational therapy. Facilities will be permitted to bill patients directly for
services rendered in excess of these caps; however, there can be no assurance
that Sun will receive any payments in excess of these caps. There also can be no
assurance that such yet-to-be-developed fee schedules or caps will not have a
material adverse effect on Sun.
 
    POTENTIAL REDUCTION OF REIMBURSEMENT RATES FROM THIRD PARTY PAYORS AND
     POSSIBLE ADVERSE IMPACT ON FUTURE OPERATING RESULTS.
 
    Various cost containment measures adopted by governmental and private pay
sources have begun to restrict the scope and amount of reimbursable healthcare
expenses and limit increases in reimbursement rates for medical services. Any
reductions in reimbursement levels under Medicaid, Medicare or private payor
programs and any changes in applicable government regulations or interpretations
of existing regulations could significantly affect Sun's profitability.
Furthermore, government programs are subject to statutory and regulatory
changes, retroactive rate adjustments, administrative rulings and government
funding restrictions, all of which may materially affect the rate of payment to
Sun's facilities and its therapy and pharmaceutical businesses. There can be no
assurance that payments under governmental or private payor programs will remain
at levels comparable to present levels or will be adequate to cover the costs of
providing services to patients eligible for assistance under such programs.
Significant decreases in utilization and limits on reimbursement could have a
material adverse effect on Sun's financial condition and results of operations,
including the possible impairment of certain assets. Most recently, in the BBA,
Congress amended the reimbursement provisions applicable to exempt hospitals
services, skilled nursing, therapy and other ancillary services. See "--Risk
Factors Concerning Sun--Risks Associated with the Development and Expansion of
Ancillary Services." See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included in Sun's Annual Report on Form
10-K for the year ended December 31, 1997 and Sun's Quarterly Report on Form
10-Q for the fiscal quarter ended March 31, 1998, incorporated by reference
herein, for a summary of sources of revenues for Sun for the three most recent
fiscal years.
 
    Reimbursement for therapy services is currently evaluated under Medicare's
reasonable cost principles. Under current law, the reasonable costs for physical
therapy and respiratory therapy services may not exceed an amount equal to the
salary that would reasonably have been paid to a therapist for providing the
services (together with certain additional costs) within each geographical area.
Salary equivalency guidelines are the amounts published by the Health Care
Financing Administration ("HCFA"), which reflect the prevailing salary, fringe
benefit and expense factors as determined by HCFA. HCFA then uses the salary
equivalency guidelines to determine the reimbursement rates for physical therapy
and respiratory therapy costs. Although salary equivalency guidelines will no
longer be effective following the implementation of PPS and fee schedule
reimbursement, HCFA has published new equivalency guidelines.
 
    On January 30, 1998, HCFA revised salary equivalency guidelines for
respiratory therapy and physical therapy, and for the first time published new
salary equivalency guidelines for speech therapy and occupational therapy. HCFA
has applied the new salary equivalency guidelines to all services rendered on or
after April 10, 1998. Implementation of these guidelines has increased
reimbursement rates for respiratory therapy and physical therapy, but reduced
reimbursement rates for speech therapy and occupational therapy. The effect of
the changes could have a material adverse impact on Sun's results of operations.
The salary equivalency guidelines rates will have no continuing impact on
reimbursement for therapy services rendered to a Medicare patient receiving
post-hospital extended care services following the commencement of PPS, because
under PPS therapy services will be bundled into each facility's per
 
                                       50
<PAGE>
diem reimbursement from Medicare. In addition, the salary equivalency guidelines
will have no continuing impact on therapy services rendered to all other
Medicare patients after the institution of fee schedule reimbursement for
therapy services, which may be effective as early as July 1, 1998.
 
    In 1995, and periodically since then, HCFA has provided information to
intermediaries for use in determining reasonable costs for occupational and
speech therapy. This information, although not intended to impose limits on such
costs, suggests that fiscal intermediaries should carefully review costs that
appear to be in excess of what a "prudent buyer" would pay for those services.
While the effect of these directives is uncertain, they are a factor considered
by such intermediaries in evaluating the reasonableness of amounts paid by
providers for the services of Sun's rehabilitation therapy subsidiary. When
salary equivalency guidelines, PPS and fee schedules are implemented,
reimbursement for these services will no longer be on a "pass through" basis and
the HCFA directives and reasonable cost guidelines discussed in this paragraph
will become moot as to services rendered after their effectiveness. In addition,
some intermediaries require facilities to justify the cost of contract
therapists versus employed therapists as an aspect of the "prudent buyer"
analysis. With respect to rehabilitation therapy services provided to affiliated
facilities, a retroactive adjustment of Medicare reimbursement could be made for
some prior periods. With respect to nonaffiliated facilities, an adjustment of
reimbursement rates for therapy services could result in indemnity claims
against Sun, based on the terms of substantially all of Sun's existing contracts
with such facilities, for payments previously made by such facilities to Sun
that are reduced by Medicare in the audit process. Any change in reimbursement
rates resulting from implementation of the HCFA directives or a reduction in
reimbursement as a result of a change in application of reasonable cost
guidelines could have a material adverse effect on Sun's financial condition and
results of operations (depending on the rates adopted) and customers' ability to
pay for prior and continuing services. When PPS with respect to Medicare Part A
(effective for Sun's facilities on January 1, 1999) and fee schedules with
respect to Medicare Part B (which may be effective as early as July 1, 1998) are
implemented, Sun's facilities' reimbursement will no longer be affected by
salary equivalency guidelines and the cost reporting settlement process for
services rendered after their effectiveness. See "--Risk Factors Concerning
Sun--Risks Relating to Prospective Payment System" and "--Risks Associated with
Development and Expansion of Ancillary Services."
 
    RISKS ASSOCIATED WITH REIMBURSEMENT PROCESS AND COLLECTIBILITY OF CERTAIN
     ACCOUNTS RECEIVABLE.
 
    Sun derives a substantial percentage of its total revenues from Medicare,
Medicaid and private insurance. Sun's financial condition and results of
operations may be affected by the revenue reimbursement process, which is
complex and can involve lengthy delays between the recognition of revenue and
the time reimbursement amounts are settled. Net revenues realizable under
third-party payor agreements are subject to change due to examination and
retroactive adjustment by payors during the settlement process. Payors may
disallow in whole or in part requests for reimbursement based on determinations
that certain costs are not reimbursable or reasonable or because additional
supporting documentation is necessary. Sun recognizes revenues from third-party
payors and accrues estimated settlement amounts in the period in which the
related services are provided. Sun estimates these settlement balances by making
determinations based on its prior settlement experience and its understanding of
the applicable reimbursement rules and regulations. The majority of third-party
payor balances are settled within two to three years following the provision of
services. Sun has experienced differences between the net amounts accrued and
subsequent settlements, which differences are recorded in operations at the time
of settlement. For example, in the fourth quarter of 1997, Sun recorded negative
revenue adjustments totalling approximately $15.0 million resulting from changes
in accounting estimates of amounts realizable from third-party payors. These
changes in accounting estimates primarily arose out of the settlement in late
1997 of certain facility cost reports for 1994 and 1995 and also include
estimated charges for projected settlements in 1996.
 
    Accounts receivable for therapy services have also increased in part because
the ability of nonaffiliated facilities to provide timely payments has been
impacted by their receipt of payments from fiscal intermediaries which, in some
instances, have been delayed due to the fiscal intermediaries conducting
 
                                       51
<PAGE>
reviews of facilities' therapy claims. In addition, accounts receivable have
increased in part because of the growth in Sun's inpatient, therapy and
pharmaceutical services businesses since December 31, 1996. During 1996 and the
first two quarters of 1997, as a result of these factors, accounts receivable
for therapy services grew disproportionately to the growth in revenue of that
line of business. As a result, Sun increased its provision for losses on
accounts receivable in mid-1996. No assurance can be given that further
increases in the provision for losses on accounts receivable will not be
required.
 
    Sun's financial condition and results of operations would be materially and
adversely affected if the amounts actually received from third-party payors in
any reporting period differs materially from the amounts accrued in prior
periods. Sun's financial condition and results of operations may also be
affected by the timing of reimbursement payments and rate adjustments from
third-party payors. Sun has from time to time experienced delays in receiving
reimbursement from government agencies. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources" included in Sun's Annual Report on Form 10-K for the year ended
December 31, 1997 and Sun's Quarterly Report on Form 10-Q for the fiscal quarter
ended March 31, 1998, incorporated by reference herein.
 
    POTENTIAL LIABILITY FOR REIMBURSEMENTS PAID TO FORMER OPERATORS OF ACQUIRED
     FACILITIES.
 
    Sun's growth strategy relies heavily on the acquisition of long-term and
subacute care facilities. Regardless of the legal form of the acquisition, the
Medicare and Medicaid programs often require that Sun assume certain obligations
relating to the reimbursement paid to the former operators of facilities
acquired by Sun. From time to time, fiscal intermediaries and Medicaid agencies
examine cost reports filed by such predecessor operators. If, as a result of any
such examination, it is concluded that overpayments to a predecessor operator
were made, Sun, as the current operator of such facilities, may be held
financially responsible for such overpayments. At this time Sun is unable to
predict the outcome of any existing or future examinations. See "--Risk Factors
Concerning the Mergers--Difficulty of Integrating Acquired Operations."
 
    RISKS ASSOCIATED WITH RELATED PARTY TRANSACTIONS.
 
    Current Medicare regulations that apply to transactions between related
parties, such as Sun's subsidiaries, are relevant to the amount of Medicare
reimbursement that Sun is entitled to receive for the rehabilitation and
respiratory therapy and pharmaceutical services that it provides to Sun-operated
facilities. These related-party regulations require that, among other things, a
substantial part of the rehabilitation and respiratory therapy services or
pharmaceutical services, as the case may be, of the relevant subsidiary be
transacted with nonaffiliated entities in order for Sun to receive reimbursement
for services provided to Sun-operated facilities at the rates applicable to
services provided to nonaffiliated entities. The related-party regulations do
not indicate a specific level of services that must be provided to nonaffiliated
entities in order to satisfy the "substantial part" requirement of such
regulations. In instances where this issue has been litigated by others, no
consistent standard has emerged as to the appropriate threshold necessary to
satisfy the "substantial part" requirement. See "--Risk Factors Concerning Sun--
Risks Associated with the Development and Expansion of Ancillary Services." See
"Business--United States Revenue Sources--Medicare" included in Sun's Annual
Report on Form 10-K for the year ended December 31, 1997, incorporated by
reference herein.
 
    Sun believes that it satisfies the requirements of these regulations
regarding nonaffiliated businesses. Sun's net revenues from rehabilitation
therapy services, including net revenues for temporary therapy staffing
services, provided to nonaffiliated facilities represented 63%, 73%, 74%, 70%
and 68% of total rehabilitation and temporary therapy staffing services net
revenues for the three months ended March 31, 1998 and for the years ended
December 31, 1995, 1996 and 1997, and for the three months ended December 31,
1997, respectively. Respiratory therapy services provided to nonaffiliated
facilities represented 56%, 64%, 55%, 63% and 70% of total respiratory therapy
services net revenues for the three
 
                                       52
<PAGE>
months ended March 31, 1998 and for the for the period from the date of
acquisition of SunCare on May 5, 1995 to December 31, 1995, for the years ended
December 31, 1996 and 1997, and for the three months ended December 31, 1997,
respectively. Sun's respiratory therapy operations did not provide services to
affiliated facilities prior to the acquisition of SunCare on May 5, 1995. Net
revenues from pharmaceutical services billed to nonaffiliated facilities
represented 78%, 78%, 78%, 79% and 81% of total pharmaceutical services revenues
for three months ended March 31, 1998 and for the years ended December 31, 1995,
1996 and 1997, and for the three months ended December 31, 1997, respectively.
If, upon audit by Federal or state reimbursement agencies, such agencies find
that these regulations have not been satisfied for these periods, and if, after
appeal, such findings are sustained, Sun could be required to refund the
difference between its cost of providing these services to any entity found to
be subject to the related party regulations and the higher amount actually
received. See "--Risk Factors Concerning Sun-- Risks Associated with the
Development and Expansion of Ancillary Services."
 
    If Sun fails to satisfy these regulations in the future, the reimbursement
that Sun receives for rehabilitation and respiratory therapy and pharmaceutical
services provided to its own facilities would be significantly reduced, as a
result of which Sun's financial condition and results of operations would be
materially and adversely affected for so long as Medicare and Medicaid continue
to reimburse on the basis of reasonable cost. While Sun believes that it has
satisfied and will continue to satisfy the requirements of these regulations
regarding nonaffiliated businesses, there can be no assurance that its position
would prevail if contested by relevant reimbursement agencies. The foregoing
statements with respect to Sun's ability to satisfy these regulations are
forward looking and could be affected by a number of factors, including the
interpretation of Medicare regulations by Federal or state reimbursement
agencies and Sun's ability to provide services to nonaffiliated facilities. When
the salary equivalency guidelines, PPS and fees schedules are implemented, the
Medicare impact of the related party rule, will be significantly reduced. See
"--Risk Factors Concerning Sun--Risks Related to Prospective Payment System"
included in Sun's Annual Report on Form 10-K for the year ended December 31,
1997, and "Management's Discussion and Analysis of Results of Operations and
Financial Condition," included in Sun's Annual Report on Form 10-K for the year
ended December 31, 1997 and Sun's Quarterly Report on Form 10-Q for the fiscal
quarter ended March 31, 1998, incorporated by reference herein.
 
    POTENTIAL ADVERSE EFFECT OF CHANGE IN REVENUE SOURCES.
 
    Changes in the mix of patients among the Medicaid, Medicare and private pay
categories, and among different types of private pay sources, can significantly
affect the revenues and the profitability of Sun's operations. There can be no
assurance that Sun will continue to attract and retain private pay patients or
maintain its current payor or revenue mix.
 
    In addition, there can be no assurance that the facilities operated by Sun,
or the provision of services and products by Sun, now or in the future, will
initially meet or continue to meet the requirements for participation in the
Medicare and Medicaid programs, or that Sun will continue to qualify for the
levels of reimbursement it has in the past with respect to reimbursement for
rehabilitation therapy, respiratory therapy and pharmaceutical services provided
by Sun-operated facilities. A loss of Medicare or Medicaid certification or a
change in Sun's reimbursement under Medicare or Medicaid could have an adverse
effect on its financial condition and results of operations. See "--Risk Factors
Concerning Sun--Potential Reduction of Reimbursement Rates from Third Party
Payors and Possible Adverse Impact on Future Operating Results," "--Risk Factors
Concerning Sun--Risks Associated with Reimbursement Process and Collectibility
of Certain Accounts Receivables," "--Risk Factors Concerning Sun--Risks
Associated with Related Party Transactions," "--Risk Factors Concerning
Sun--Risk of Adverse Effect of Future Healthcare Reform" and "--Risk Factors
Concerning Sun--Investigations; Uncertain Impact on Future Operating Results."

<PAGE>
    INVESTIGATIONS; UNCERTAIN IMPACT ON FUTURE OPERATING RESULTS.
 
    Sun's subsidiaries, including those that provide subacute and long-term
care, rehabilitation and respiratory therapy and pharmaceutical services, are
engaged in industries that are extensively regulated. See "--Risk Factors
Concerning Sun--Potential Adverse Impact from Extensive Regulation." As such, in
the ordinary course of business, the operations of these subsidiaries are
continuously subject to state and Federal regulatory scrutiny, supervision and
control. Such regulatory scrutiny often includes inquiries, investigations,
examinations, audits, site visits and surveys, some of which may be non-routine.
If a provider is ever found to have engaged in improper practices, it could be
subjected to civil, administrative, or criminal fines, penalties or
restitutionary relief, and reimbursement authorities could also seek the
suspension or exclusion of the provider or individuals from participation in
their program.
 
    In January 1995, Sun learned that it was the subject of a pending Federal
investigation. The investigating agencies are the United States Department of
Health and Human Services' Office of Inspector General ("OIG") and the United
States Department of Justice. At this time, Sun does not know the full scope of
the investigation. However, Sun currently believes that the investigation is
focused principally on whether Sun provided and billed for unnecessary or
unordered therapy services to residents of skilled nursing facilities and
whether Sun adequately documented the therapy services that it provided.
 
    In July 1997, the Criminal Division of the U.S. Department of Justice
informed Sun that it had completed its investigation of Sun, and that it would
not initiate any actions against Sun or any individuals. The investigation by
the Civil Division of the Department of Justice and the OIG is still proceeding.
The government continues to collect information, and Sun continues to cooperate
with the investigators. Sun and the government have had preliminary discussions,
and Sun expects to have continuing discussions, regarding a possible settlement
of the investigation.
 
    Sun is unable to determine at this time when the investigation will be
concluded, how large a monetary settlement the government may seek, the nature
of any other remedies that may be sought by the government, whether or when a
settlement will in fact occur or whether any such settlement or any other
outcome of the investigation will have a material adverse effect on Sun's
financial condition or results of operations. The foregoing statements with
respect to the outcome of the investigation are forward-looking and could be
affected by a number of factors, including the actual scope of the
investigation, the government's factual findings and the interpretation of
Federal statutes and regulations by the government and Federal courts and
whether any such factual findings could serve as a basis for proceedings by
other governmental authorities. From time to time the negative publicity
surrounding the investigation has in the past adversely affected the private pay
enrollment in certain inpatient facilities and slowed Sun's success in obtaining
additional outside contracts in the rehabilitation therapy business, which
resulted in higher than required therapist staffing levels. Negative publicity
in the future could have a similar effect. See "--Risk Factors Concerning
Sun--Risks Associated with the Development and Expansion of Ancillary Services."
 
    In 1996, the Connecticut Attorney General's office and the Connecticut
Department of Social Services ("DSS") began an investigation and initiated a
hearing in order to determine whether Sun's long-term care subsidiary submitted
false and misleading fiscal information on its 1993 and 1994 Medicaid cost
reports. Since 1997, the investigation has also covered information for the 1995
cost year as well as cost reporting periods prior to 1993. The information under
review includes submissions and representations by the long-term care subsidiary
and Sun's chief executive officer. The evidentiary phase of the hearing has
concluded. Sun submitted a settlement offer to the DSS in February 1998 and the
DSS responded with a counter-offer in late May 1998. Based on Sun's current
understanding of the investigation and the terms of the counter-offer, Sun does
not believe the terms of a settlement, if any, would have a material adverse
effect on Sun's business, financial condition or results of operations. However,
Sun is unable to determine at this time when the proceedings will be concluded
or, if no settlement is reached, whether the DSS will seek further
administrative action or Medicaid reimbursement sanctions. No assurance may be
given that a settlement will in fact occur or whether any such settlement or
other outcome of the investigation will not have a material adverse effect on
Sun's business, financial condition or results of operations. The foregoing
 
                                       54
<PAGE>
statement with regard to the outcome of this investigation is forward looking
and could be affected by a number of factors, including factual findings and the
interpretation of applicable laws and regulations by the Attorney General and
the DSS and whether any such factual findings could serve as a basis for
proceedings by other governmental authorities in Connecticut or elsewhere.
 
    In 1997, Sun was notified by a law firm representing several national
insurance companies that these companies believed that Sun had engaged in
improper billing and other practices in connection with Sun's delivery of
therapy and related services. In response, Sun began discussions directly with
these insurers and hopes to resolve these matters without litigation; however,
Sun is unable at this time to predict whether it will be able to do so, what the
eventual outcome may be or the extent of its liability, if any, to these
insurers.
 
    Pursuant to the Health Insurance Portablility and Accountability Act of 1996
(the "Act"), Congress has provided additional funding to Medicare and Medicaid
enforcement units to investigate potential cases of reimbursement abuse in the
health care services industry. The Act also sets guidelines to encourage
federal, state, and local law enforcement agencies to share general information
and to coordinate specific law enforcement activities including conducting
investigations, audits, evaluations, and inspections relating to the delivery of
and payment for health care. From time to time enforcement agencies conduct
audits, inspections and investigations with respect to the reimbursement
activities of the subsidiaries of Sun. Sun is currently the subject of several
such investigations. It is Sun's practice to cooperate fully in such matters.
 
    POTENTIAL ADVERSE IMPACT FROM EXTENSIVE REGULATION.
 
    Sun is subject to extensive Federal, state and local government regulation
relating to licensure, conduct of operations, ownership of facilities, expansion
of facilities and services and reimbursement for services. As such, in the
ordinary course of business, Sun's operations are continuously subject to state
and Federal regulatory scrutiny, supervision and control. Such regulatory
scrutiny often includes inquiries, investigations, examinations, audits, site
visits and surveys, some of which may be nonroutine. All of the facilities
operated or managed by Sun are required to be licensed in accordance with the
requirements of state and local agencies having jurisdiction over their
operations. Most of Sun's facilities are also certified as providers under the
Medicaid and Medicare programs. The long-term care facilities, as well as Sun's
rehabilitation therapy and pharmaceutical operations, are subject to periodic
inspection by governmental and other authorities to assure continued compliance
with regulatory procedures and licensing under state law and certification under
the Medicare and Medicaid programs. The failure to obtain or renew any required
regulatory approvals or licenses or to comply with applicable regulations in the
future could adversely affect Sun's financial condition and results of
operations. See "--Risk Factors Concerning Sun-- Investigations; Uncertain
Impact on Future Operating Results." To the extent that Certificates of Need
("CONs") or other similar approvals are required for expansion of Sun's
operations, either through acquisitions or additions to or provision of new
services at such facilities, such expansion could be adversely affected by the
failure to obtain such CONs or approvals. See "--Risk Factors Concerning Sun--
Risks Related to Prospective Payment System."
 
    Medicare and Medicaid antifraud and abuse laws prohibit certain business
practices and relationships that might affect the provision and cost of health
care services reimbursable under Medicare and Medicaid. Expressly prohibited are
kickbacks, bribes and rebates related to Medicare or Medicaid referrals. Federal
laws also provide civil and criminal penalties for any false or fraudulent
statements, knowingly made, in any claim for payment under a Federal or state
health care program as well as any material omissions in such claims. In
addition, certain states have adopted fraud and abuse and false claims laws that
prohibit specified business practices. Sanctions for violating these laws
include criminal penalties and civil sanctions, including fines and possible
exclusion from the Medicare and Medicaid programs.
 
    In many states, the temporary therapy staffing industry is regulated, and
CareerStaff must be registered or qualify for an exemption from registration.
While these regulations have had no material effect on the conduct of
CareerStaff's business to date, there can be no assurance that future
regulations will not have such an effect. In addition, the healthcare industry
to which CareerStaff provides therapists is
 
                                       55
<PAGE>
subject to numerous Federal, state and local regulations. The majority of states
require therapists practicing in such states to be licensed or certified.
CareerStaff has occasionally experienced difficulties in moving therapists from
one state to another because of state licensing requirements. Sun does not
believe this has had a material adverse effect on its financial condition or
results of operations.
 
    There can be no assurance that Sun's business in the future will not be
materially adversely affected by licensing requirements of state and Federal
authorities and by amendments to Federal law, which mandate that nursing homes
provide rehabilitation therapy services to their patients and authorize Medicare
reimbursement for such services, or by new reimbursement rates proposed by HCFA.
See "Business-- Government Regulation" included in Sun's Annual Report on Form
10-K for the year ended December 31, 1997, incorporated by reference herein.
 
    NO ASSURANCE OF CONTINUED RAPID GROWTH.
 
    Since its formation in 1989, Sun has implemented an aggressive program of
expansion of its business through the acquisition of additional long-term and
subacute care facilities and other operations. From January 1994 through
December 31, 1997, Sun acquired or assumed the net operations or management of
408 long-term and subacute care facilities with a total of 39,227 licensed beds
in the United States, the United Kingdom, Australia, Spain and Germany. During
this same period, Sun opened 20 facilities with a capacity of 1,624 licensed
beds. During such period, Sun has also acquired pharmacies, temporary therapy
staffing providers, outpatient rehabilitation clinics, home care agencies,
ambulatory surgery centers and a respiratory therapy company, and has
experienced significant internal growth, particularly in its therapy operations.
Sun's total net revenues increased from $135.7 million for the year ended
December 31, 1992, to $2.0 billion for the year ended December 31, 1997.
Similarly, net earnings before the extraordinary loss increased from $4.4
million for the year ended December 31, 1992, to $54.7 million for the year
ended December 31, 1997. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" included in Sun's Annual Report on Form
10-K for the year ended December 31, 1997 and Sun's Quarterly Report on Form
10-Q for the fiscal quarter ended March 31, 1998, incorporated by reference
herein. Sun intends to continue to pursue its acquisition strategy in the
future. In making such acquisitions, Sun competes with other providers, many of
which have greater financial resources than Sun. There can be no assurance that
suitable acquisitions will be identified or completed in the future.
 
    Sun has used both Sun Common Stock and indebtedness to fund many of its
significant acquisitions. Although Sun did not utilize Sun Common Stock as
acquisition consideration from February 1996 through February 1997, Sun issued
or reserved for issuance approximately 23.3 million shares of Sun Common Stock
in acquisitions from January 1994 to January 1996. Sun has also undertaken
significant borrowing to finance the acquisitions of Regency, Mediplex and other
transactions and to support expanded operations (including the assumption or
guarantee by Sun of $338.6 million of Mediplex indebtedness as of the date of
the acquisition of Mediplex and the assumption or refinancing of $229.2 million
of indebtedness in connection with the Regency Acquisition), and would assume
$192.0 million of indebtedness (excluding $19.8 million which will be eliminated
in consolidation) if the Mergers are consummated (based on RCA's March 31, 1997
balance sheet and assuming Sun acquires the remaining 35% of Contour for Sun
Common Stock). Sun's Credit Facility and certain of Sun's indentures limit Sun's
ability to raise additional indebtedness which may inhibit Sun's ability to use
debt financing to consummate acquisitions. See "--Risk Factors Concerning
Sun--Substantial Leverage; Ability to Service Debt" and "Unaudited Pro Forma
Combined Financial Statements." See "Business--Acquisitions" included in Sun's
Annual Report on Form 10-K for the year ended December 31, 1997, incorporated by
reference herein. The ability to utilize Sun Common Stock for acquisition or
financing purposes will depend on the market price of the Sun Common Stock,
which has from time to time been subject to heightened volatility resulting
primarily from uncertainties regarding certain Medicare reimbursement policies
and a government investigation of Sun's rehabilitation therapy subsidiary. See
"--Risk Factors Concerning Sun--Potential Reduction of Reimbursement Rates from
Third Party Payors and Possible Adverse Impact on Future Operating

Results," "--Risk Factors Concerning Sun--Risks Associated with Reimbursement
Process and Collectibility of Certain Accounts Receivable," "--Risk Factors
Concerning Sun--Risks Associated with Related Party Transactions" and "--Risk
Factors Concerning Sun--Investigations; Uncertain Impact on Future Operating
Results."
 
    Because of operating and financing constraints resulting from acquisitions
and internal growth, there can be no assurance that Sun will have adequate cash
or borrowing capacity and other resources to compete effectively for future
acquisitions or will be able in the future to continue to engage as actively in
acquisitions as it has in the past, and uncertainties regarding reimbursement
rates for therapy, the outcome of the government investigation of Sun's
rehabilitation therapy subsidiary or a material reduction in such rates could
limit internal growth of Sun's therapy business. Pursuant to the Credit
Facility, Sun will be required to obtain the consent of its principal bank
lenders in connection with significant future acquisitions. In addition, to the
extent Sun's operational, administrative and financial resources are strained by
its acquisition program, Sun's ability to integrate acquired operations may
become more protracted. Although Sun is continuously engaged in discussions
regarding future acquisitions, there can be no assurance that any acquisitions
will be completed, or that Sun's historic rate of growth in assets, revenues or
net revenues will be sustained. See "--Risk Factors Concerning the
Mergers--Management of Growth," "--Risk Factors Concerning the
Mergers--Difficulty of Integrating Acquired Operations," "--Risk Factors
Concerning Sun--Potential Liability for Reimbursements Paid to Former Operators
of Acquired Facilities" and "--Risk Factors Concerning Sun--Substantial
Leverage; Ability to Service Debt." See "Business-- Acquisitions" included in
Sun's Annual Report on Form 10-K for the year ended December 31, 1997,
incorporated by reference herein.
 
    FINANCIAL RESULTS SUBJECT TO FLUCTUATION.
 
    Sun's financial results may fluctuate on a quarterly basis as a result of a
number of factors, including the timing of acquisitions, any associated charges
to earnings and the financial performance of acquired companies. A material
shortfall in revenue or increase in expenses in a given quarter, or a delayed or
unrealized ability to achieve synergies from acquisitions, could have a material
adverse effect on Sun's earnings. Sun believes that quarterly comparisons of
Sun's revenues and operating results should not be relied on as necessarily
being indicative of future performance. Operating results in any particular
quarter that do not meet the expectations of securities analysts could cause
volatility in the price of the Sun Common Stock. See "--Risk Factors Concerning
the Mergers--Difficulty of Integrating Acquired Operations" and "--Risk Factors
Concerning Sun--Potential Volatility of Stock Price."
 
    RISK OF EXPANSION OF INTERNATIONAL OPERATIONS; FOREIGN EXCHANGE RISK.
 
    Sun currently conducts business outside the United States in the United
Kingdom, Spain, Germany, Australia and Canada. Foreign operations accounted for
approximately 9%, 10%, 4% and 2% of Sun's total net revenues during the three
months ended March 31, 1998, the years ended December 31, 1997, 1996 and 1995,
respectively, and 24% of Sun's consolidated total assets as of December 31,
1997. See "Business--Acquisitions" included in Sun's Annual Report on Form 10-K
for the year ended December 31, 1997, incorporated by reference herein. Sun
expects that its revenues and operations attributable to international
operations may increase and substantially contribute to Sun's growth and
earnings in the future. Accordingly, as Sun's international operations continue
to grow, adverse results from Sun's international operations could adversely
affect Sun's financial condition and results of operations. Sun intends to
expand its international operations through the acquisition of operational
facilities and the construction and development of new facilities. In the past,
Sun has constructed and developed new facilities to a more significant degree in
its international expansion than it has in the United States, where Sun's growth
has been primarily due to the acquisition of operational facilities. In addition
to the capital expenditures involved in the construction and development of new
facilities, Sun expects to incur substantial losses in the first year of
operation of a new facility. As a result, the financial condition and
 
                                       57
<PAGE>
results of operations of Sun's international operations could be adversely
affected in any period in which a significant number of facilities are being
constructed or developed or are in their first year of operation. The success of
Sun's operations in and expansion into international markets depends on numerous
factors, many of which are beyond its control. Such factors include, but are not
limited to, economic conditions and healthcare regulatory systems in the foreign
countries in which Sun operates. In addition, international operations and
expansion may increase Sun's exposure to certain risks inherent in doing
business outside the United States, including slower payment cycles, unexpected
changes in regulatory requirements, potentially adverse tax consequences,
currency fluctuations, restrictions on the repatriation of profits and assets,
compliance with foreign laws and standards and political risks.
 
    Sun's financial condition and results of operations are subject to foreign
exchange risk. Because of Sun's foreign growth strategies, Sun does not expect
to repatriate funds invested overseas and, therefore, foreign currency
transaction exposure is not normally hedged. Exceptional planned foreign
currency cash flow requirements, such as acquisitions overseas, are hedged
selectively to prevent fluctuations in the anticipated foreign currency value.
Changes in the net worth of Sun's foreign subsidiaries arising from currency
fluctuations are accumulated in the translation adjustments component of
stockholders' equity.
 
    YEAR 2000 RISK.
 
    In common with users of computers around the world, Sun is investigating if
and to what extent the date change from 1999 to 2000 may affect its networks and
systems. Sun expects to incur internal staff costs, external consulting costs,
and other expenses related to infrastructure and facility enhancement necessary
to prepare the systems for the year 2000. Although the total cost to Sun of
achieving year 2000 compliant systems is not expected to be material to Sun's
operations or financial condition, there can be no assurance that the costs will
be as expected or that this program will be successful or that the date change
from 1999 to 2000 will not materially adversely affect Sun's business, financial
condition and results of operations. The ability of third parties with which Sun
transacts business to adequately address their year 2000 issues is outside Sun's
control. Although Sun will seek alternative vendors, where its current vendors
are unwilling or unable to become year 2000 compliant in a timely manner, there
can be no assurance that Sun's business, financial condition and results of
operations will not be materially adversely affected by the ability of third
parties dealing with Sun, including Medicare and Medicaid, to also manage the
effect of the year 2000 date change.
 
    INCREASED LABOR COSTS AND AVAILABILITY OF PERSONNEL.
 
    In recent years Sun has experienced increases in its labor costs primarily
due to higher wages and greater benefits required to attract and retain
qualified personnel, increased staffing levels in its long-term and subacute
care facilities due to greater patient acuity and the hiring and retention of
staff therapists. Although Sun expects labor costs to continue to increase in
the future, it is anticipated that any increase in costs will generally result
in higher patient rates in subsequent periods, subject to the time lag in most
states between increases in reimbursable costs and the receipt of related
reimbursement rate increases. Since under the upcoming PPS and fee schedules
reimbursement payments will no longer be on a "pass through" basis, increases in
costs may no longer result in corresponding increases in reimbursement. See
"--Risk Factors Concerning Sun--Potential Reduction of Reimbursement Rates from
Third Party Payors and Possible Adverse Impact on Future Operating Results,"
"--Risk Factors Concerning Sun--Risks Associated with Reimbursement Process and
Collectibility of Certain Accounts Receivable," "--Risk Factors Concerning
Sun--Potential Liability for Reimbursements Paid to Former Operators of Acquired
Facilities" and "--Risk Factors Concerning Sun--Risks Associated with Related
Party Transactions."
 
    In the past, the healthcare industry, including Sun's long-term and subacute
care facilities, has experienced a shortage of nurses to staff healthcare
operations and, more recently, the healthcare industry has experienced a
shortage of therapists. Sun is not currently experiencing a nursing or therapist
shortage, but it competes with other healthcare providers for nursing and
therapist personnel and may compete with
 
                                       58
<PAGE>
other service industries for persons serving Sun in other capacities, such as
certified nursing assistants. A nursing, therapist or certified nursing
assistant shortage could force Sun to pay higher salaries and make greater use
of higher-cost temporary personnel. A lack of qualified personnel might also
require Sun to reduce its census or admit patients requiring a lower level of
care, both of which could adversely affect operating results.
 
    SUBSTANTIAL COMPETITION.
 
    Sun operates in a highly competitive industry. The nature of competition
varies by location. Sun's facilities generally operate in communities that are
also served by similar facilities operated by others. Some competing facilities
are located in buildings that are newer than those operated by Sun and provide
services not offered by Sun, and some are operated by entities having greater
financial and other resources and longer operating histories than Sun. In
addition, some facilities are operated by nonprofit organizations or government
agencies supported by endowments, charitable contributions, tax revenues and
other resources not available to Sun. Some hospitals that either currently
provide long-term and subacute care services or are converting their
under-utilized facilities into long-term and subacute care facilities are also a
potential source of competition to Sun. Sun also competes with other companies
in providing rehabilitation therapy services and pharmaceutical products and
services to the long-term care industry and in employing and retaining qualified
therapists and other medical personnel. Many of these competing companies have
greater financial and other resources than Sun. There can be no assurance that
Sun will not encounter increased competition in the future that would adversely
affect its financial condition and results of operations.
 
    POTENTIAL CONFLICTS OF INTEREST FROM RELATED PARTY TRANSACTIONS.
 
    At March 31, 1998, 58 of Sun's 321 long-term and subacute care facilities in
the United States were leased or subleased from John E. Bingaman or Zev Karkomi,
two of Sun's directors, or from partnerships or corporations in which such
directors are general or limited partners, directors or stockholders or
otherwise have a significant equity holding. Sun believes the terms of all of
the foregoing leases and subleases to which it is a party are as favorable to
Sun as those that could have been obtained in arm's length transactions with
nonaffiliated parties at the time of such transactions. However, contractual
relationships with entities affiliated with members of Sun's board of directors
create the potential for conflicts of interest. Sun will likely continue to
enter into leases and subleases with members of its board of directors and their
affiliates. There can be no assurance that these contractual relationships with
members of Sun's board of directors and their affiliates will not create actual
conflicts of interest.
 
    ADEQUACY OF CERTAIN INSURANCE.
 
    Healthcare companies are subject to medical professional liability, personal
injury and other liability claims that are customary risks inherent in the
operation of health facilities and are generally covered by insurance. Sun
maintains property, liability and professional liability insurance policies in
amounts and with such coverages and deductibles that are deemed appropriate by
Sun, based upon historical claims, industry standards and the nature and risks
of its business. Sun also requires that physicians practicing at its facilities
carry medical professional liability insurance to cover their respective
individual professional liabilities. There can be no assurance that such
insurance will continue to be available at acceptable costs or that claims in
excess of the current insurance coverage or claims not covered by insurance will
not be asserted against Sun.
 
    HEALTH INSURANCE AND WORKERS' COMPENSATION INSURANCE.
 
    Sun has self-insured the healthcare risks of its employees who select
coverage under certain Sun-sponsored plans. Workers' compensation coverage is
effected through self-insurance or high-deductible insurance programs, except
that Sun's long-term and subacute care subsidiary is a nonsubscriber to the
 
                                       59
<PAGE>
workers' compensation programs in Texas. Substantially all of the risk of
workers' compensation claims under the high-deductible programs are assumed by
Sun and such risks are comparable to those of a self-insured plan. The
high-deductible program provides coverage in all states in which Sun operates
with the exception of Arizona, Illinois, Massachusetts, Washington and
Connecticut (which are self-insured), Texas (in which Sun is a nonsubscriber)
and Rhode Island, Ohio, Maine, Nevada and Wyoming (in which Sun is required to
utilize the specific programs offered by those states). The costs of paying for
healthcare and workers' compensation claims can fluctuate depending on the type
and number of claims in any given period. There can be no assurance that the
amounts Sun will be required to pay for these types of claims will not increase.
 
    ADDITIONAL SHARES TO BE ISSUED BY SUN; SHARES ELIGIBLE FOR FUTURE SALE.
 
    If the Mergers had been consummated on May 20, 1998, when the Sun Market
Price was $17.725, Sun would have issued an aggregate of approximately
10,927,130 shares of Sun Common Stock (including approximately 1,640,816 shares
of Sun Common Stock that will be issuable upon the exercise of assumed options
and warrants to purchase shares of RCA Common Stock and Contour Common Stock or
upon the conversion of the shares of Sun Preferred Stock that will be issued in
exchange for the issued and outstanding shares of RCA Series F Preferred Stock
in the RCA Merger). In general, these shares will be freely tradable following
the Mergers, subject to certain volume and other resale limitations for
affiliates of Sun, RCA or Contour pursuant to Rules 144 and/or 145 under the
Securities Act. See "The RCA Merger--Limitations on Resales by Affiliates" and
"The Contour Merger--Limitations on Resales by Affiliates." An aggregate of
approximately 3,356,445 of the shares of Sun Common Stock to be issued in the
Mergers will be beneficially owned by persons who may be deemed to be affiliates
of RCA or Contour and, therefore, subject to certain volume and other resale
limitations. At the time of the Mergers substantially all existing shares of
Sun's Common Stock will be eligible for sale in the public market, subject in
certain cases to volume and other resale limitations. Sun has approximately
49,593,954 shares of Sun Common Stock outstanding net of treasury shares (based
on shares of Sun Common Stock outstanding as of March 31, 1998). As of March 31,
1998, Sun has reserved 4,873,687 shares of Sun Common Stock for issuance
pursuant to stock awards in the form of stock options, restricted stock, stock
appreciation rights, performance share awards or other stock-based awards
pursuant to Sun's stock plans. As of March 31, 1998, options to purchase
3,762,014 shares of Sun Common Stock were outstanding and unexercised. In
addition, as of March 31, 1998, 4,645,300 shares of Sun Common Stock were
issuable upon conversion of convertible debentures and 540,000 shares of Sun
Common Stock were issuable upon exercise of outstanding warrants. An increase in
the number of shares of Sun Common Stock that may become available for sale in
the public market, or the perception that such sales may occur, could adversely
affect the market price prevailing from time to time of Sun Common Stock in the
public market and could impair Sun's ability to raise additional capital through
the sale of its equity securities.
 
    CONCENTRATION OF OWNERSHIP.
 
    As of May 1, 1998, Mr. Andrew Turner, the Chairman of the Board of Directors
and Chief Executive Officer of Sun, beneficially owned approximately 13.9% of
the outstanding Sun Common Stock. While Mr. Turner's percentage of ownership is
not sufficient to enable him to control the outcome on matters submitted to
stockholders, his stock ownership, along with his position as Chairman of the
Board of Directors and Chief Executive Officer of Sun, enables him to exert
significant influence on Sun's operations. Mr. Turner's level of ownership may
have the effect of hindering a change of control of Sun.
 
    ANTI-TAKEOVER PROVISIONS; POSSIBLE ISSUANCE OF PREFERRED STOCK; VOTING BY
     GRANTOR TRUST.
 
    Sun's certificate of incorporation and by-laws contain provisions that may
make it more difficult for a third party to acquire, or discourage acquisition
bids for, Sun. In addition, approximately 4% of Sun's Common Stock is owned by a
grantor stock trust (the "Grantor Trust"), which holds such shares for
 
                                       60
<PAGE>
issuance under Sun's stock option plans and employee stock purchase plan.
Employees and nonemployee directors holding stock options and employee stock
purchase plan participants have the right to vote all of the shares held by the
Grantor Trust. The voting control of such shares of stock by employees and
management may make it more difficult for a third party to acquire (or such
ownership may discourage bids for) Sun. The provisions in Sun's certificate of
incorporation and by-laws, together with ownership of such shares by the Grantor
Trust, could limit the price that certain investors might be willing to pay in
the future for shares of Sun Common Stock. In addition, shares of Sun's
preferred stock may be issued in the future without further stockholder approval
and upon such terms and conditions and having such rights, voting powers,
preferences and relative, participating, optional and other special privileges
as the board of directors may determine. The rights of the holders of Sun Common
Stock will be subject to, and may be adversely affected by, the rights of any
holders of preferred stock that may be issued in the future. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from acquiring, a majority of the outstanding voting stock of Sun.
Sun has no present plans to issue any shares of its preferred stock, other than
the shares of Sun Preferred Stock to be issued in the RCA Merger. In addition,
Sun has adopted a stockholder rights plan that, along with certain provisions of
Sun's certificate of incorporation, have the effect of discouraging certain
transactions involving a change of control of Sun. See "Description of Sun
Capital Stock."
 
    POTENTIAL VOLATILITY OF STOCK PRICE.
 
    There has in the past been significant volatility in the market prices of
securities of healthcare companies. In particular, the market price of the Sun
Common Stock has in the past been subject to heightened volatility resulting
primarily from uncertainties regarding certain Medicare reimbursement policies
and government investigations of Sun. See "--Risk Factors Concerning
Sun--Potential Reduction of Reimbursement Rates from Third Party Payors and
Possible Adverse Impact on Future Operating Results" and "--Risk Factors
Concerning Sun--Investigations; Uncertain Impact on Future Operating Results."
Sun believes factors such as legislative and regulatory developments, continuing
uncertainties regarding certain Medicare reimbursement policies and government
investigations of Sun and quarterly variations in financial results could cause
the market price of the Sun Common Stock to fluctuate substantially. In
addition, the stock market has experienced volatility that has particularly
affected the market prices of many healthcare service companies' stocks and that
often has been unrelated to the operating performance of such companies. These
market fluctuations may adversely affect the price of the Sun Common Stock. See
"Markets and Market Prices."
 
RISK FACTORS CONCERNING RCA AND CONTOUR
 
    RESIGNATION OF INDEPENDENT ACCOUNTANTS; RESTATEMENT OF FINANCIAL STATEMENTS.
 
    On August 14, 1997, Coopers & Lybrand L.L.P. ("C&L") resigned as the
independent accountants of RCA and Contour. C&L stated that it resigned as the
independent accountants of RCA as a result of (i) concerns regarding RCA
management's inability to provide adequate support for certain inventory
adjustments; (ii) concerns regarding other potential adjustments that may have
required RCA to amend its quarterly financial statements as previously filed for
the first three quarters of fiscal 1997; (iii) concerns with respect to the
realizability of notes and advances due to RCA from affiliates; and (iv) C&L's
view that RCA should increase its allowances for doubtful accounts and
Medicaid/Medicare settlements and increase its accruals for self-insured
workers' compensation matters. Contour is not aware of any reason for C&L's
resignation as its independent accountants other than Contour's affiliation with
RCA. C&L stated that its audit report on RCA's and Contour's financial
statements for the fiscal year ended June 30, 1996 should not be relied upon
because C&L concluded that it could no longer rely on RCA and Contour
management's representations. RCA and Contour announced C&L's resignation on
August 21, 1997. On September 5, 1997, upon the recommendation of the
independent members of the audit committees of
 
                                       61
<PAGE>
RCA's and Contour's respective boards of directors, RCA and Contour each
retained Cherry, Bekaert & Holland, L.L.P. ("CB&H") to reaudit RCA's and
Contour's financial statements for the fiscal year ended June 30, 1996 and to
audit RCA's and Contour's financial statements for the fiscal year ended June
30, 1997. On October 14, 1997, RCA and Contour each filed amended annual reports
on Form 10-K/A restating their results for the fiscal year ended June 30, 1996,
and on October 23, 1997, RCA and Contour each filed amended quarterly reports on
Form 10-Q/A restating their results for the first three quarters of fiscal 1997.
See "The RCA Merger--Background of the Mergers." In light of C&L's resignation,
and the subsequent restatement of RCA and Contour's financial statements, there
is an increased risk that assumptions made by Sun regarding the financial
condition of RCA and Contour may later prove to be incorrect. See "--Risk
Factors Concerning the Mergers--Difficulty of Integrating Acquired Operations."
 
    SHAREHOLDER LITIGATION.
 
    Between August 25, 1997 and October 24, 1997, ten putative class action
lawsuits (the "Actions") were filed in the United States District Court for the
Northern District of Georgia on behalf of persons who purchased RCA Common
Stock, naming RCA and certain of its officers and directors as defendants. The
complaints have overlapping defendants and largely overlapping (although not
identical) class periods. See "The RCA Merger--Background of the Mergers." The
complaints allege violations of Federal securities laws by the defendants for
disseminating allegedly false and misleading financial statements for RCA's
fiscal year ended June 30, 1996 and its first three quarters of fiscal year
1997, which the plaintiffs allege materially overstated RCA's profitability.
Generally, each of the Actions seeks unspecified compensatory damages,
pre-judgment and post-judgment interest, attorneys' fees and costs and other
equitable and injunctive relief.
 
    On November 25, 1997, RCA, Sun and representatives of the plaintiffs entered
into a Memorandum of Understanding ("MOU"). Pursuant to the MOU, Sun has agreed
to pay $9 million into an interest-bearing escrow account maintained by Sun (the
"Escrow Account") to settle the Actions (the "Settlement"). RCA also agreed to
assign coverage under its directors' and officers' liability insurance policy,
referred to below, for these specific claims to the plaintiffs. The Settlement
is contingent upon the closing of the RCA Merger and confirmatory discovery and
is subject to the execution of definitive documentation and court approval. Upon
satisfaction of the conditions precedent to the Settlement, all claims by the
class that were or could have been asserted by the plaintiffs against RCA or any
of the other defendants in the Actions will be settled and released, and the
Actions will be dismissed in their entirety with prejudice in exchange for the
release of all funds from the Escrow Account to the plaintiffs. Court approval
of the Settlement will not be sought unless and until the RCA Merger closes,
and, therefore, no assurance can be given that the Settlement will become final
even if the RCA Merger is consummated. On February 13, 1998, the plaintiffs
filed a motion seeking to compel the immediate production of confirmatory
discovery. On March 9, 1998, RCA filed a brief opposing plaintiffs' motion
arguing, INTER ALIA, that it is not required under the MOU to provide
confirmatory discovery prior to the closing of the RCA Merger. On April 28,
1998, the court denied the plaintiffs' motion for immediate discovery but ruled
instead that if the RCA Merger closes on or before June 30, 1998 confirmatory
discovery must be produced within 30 days after the RCA Effective Time.
 
    There can be no assurance that additional actions will not be filed against
RCA and its officers and directors. However, the Actions are styled as class
actions, and should the RCA Merger close and the Settlement become final, any
additional class actions would be precluded, although individual plaintiffs may
opt out of the Settlement. There can be no assurance that the Actions will be
settled and dismissed on the terms described herein or at all. In the event that
the RCA Merger does not close, or if the Settlement is terminated for any reason
prior to the RCA Effective Time, then RCA intends to vigorously defend the
Actions, which may result in protracted litigation that may result in a
diversion of management and other resources of RCA. The payment of substantial
legal costs or damages, or the diversion of management and
 
                                       62
<PAGE>
other resources, could have a material adverse effect on RCA's business,
financial condition and results of operations.
 
    RCA is a party to indemnification agreements with certain of the other
defendants in the Actions, including RCA's officers and directors. RCA has also
purchased a directors' and officers' liability insurance policy that provides
RCA's directors and officers with liability coverage of up to $5 million per
policy year. The scope of coverage under this policy is limited, and RCA is
currently engaged in litigation with the carrier regarding whether the policy
provides indemnification for losses arising from the Actions. In
addition, pursuant to the RCA Merger Agreement, Sun has agreed to provide
indemnification to RCA's officers and directors under certain circumstances. See
"The RCA Merger--Interests of Certain Persons in the RCA Merger" and "The RCA
Merger Agreement--Directors' and Officers' Indemnification."
 
    OTHER LITIGATION.
 
    On April 30, 1997, a complaint was filed by Theratx, Inc. ("Theratx")
against RCA and certain of its officers and subsidiaries in the Superior Court
of Fulton County, Georgia, seeking approximately $1.6 million in damages (plus
interest, costs and fees of approximately $0.3 million) in connection with past
due accounts for therapy and rehabilitation services. On December 30, 1997, RCA
and Theratx settled this matter for the aggregate amount of $2.5 million, which
amount includes payment for additional services rendered subsequent to the
filing of the original complaint.
 
    On July 1, 1997, a complaint was filed against RCA by CMS Therapies, Inc.
("CMS") in the Superior Court of Mecklenburg County, North Carolina. The
complaint seeks approximately $1.3 million (plus interest and fees) in
connection with alleged breaches of therapy services agreements. On July 1,
1997, a complaint was also filed by CMS against RCA's subsidiary, Capitol Care
Management Company, Inc. ("Capitol Care"), in the Superior Court of Mecklenburg
County, North Carolina, seeking an additional $0.6 million in damages (plus
interest and fees) in connection with the alleged breach of a settlement
agreement relating to payments for therapy services. On December 15, 1997,
judgment was entered against RCA and Capitol Care in the full amount of damages
(plus interest and fees). On March 27, 1998, this matter was settled for the
aggregate amount of $2.4 million, which amount includes interest and fees.
 
    On December 10, 1997, a derivative complaint was filed by Brickell Partners
("Brickell") in the United States District Court for the District of Colorado,
naming RCA's directors, Christopher Brogdon, Edward E. Lane, Darrell C. Tucker,
Julian S. Daley and Harlan Matthews, as defendants and RCA as a nominal
defendant. The complaint alleges causes of action for breach of fiduciary duty
and gross negligence against the director defendants. The defendants responded
to the complaint on March 6, 1998 by filing a motion to transfer the action to
the United States District Court for the Northern District of Georgia and filing
motions to dismiss based upon lack of personal jurisdiction and failure to
properly state a cause of action. RCA is unable to predict at this time the
outcome of these motions or of this action.
 
    RCA is also engaged in a dispute with the Internal Revenue Service (the
"IRS") concerning the application of certain income and payroll tax liabilities
and payments. The IRS contends that RCA is delinquent in the payment of certain
taxes and has assessed taxes, penalties and interest of approximately $1.2
million in connection with the alleged underpayments. RCA contends that the IRS
has misapplied payments between income and payroll taxes and between RCA and its
affiliates. RCA has estimated and accrued $0.4 million for ultimate settlement
of this dispute and has filed a lawsuit against the IRS related to this matter.
 
    The legal costs incurred by RCA in defending itself against the Theratx
claim, the costs of settling the Theratx and CMS claims and the expenses
associated with the IRS lawsuit, have been substantial. In addition, the
Brickell claims and the IRS lawsuit, if not settled, may be protracted and may
result in a diversion of management and other resources of RCA. The payment of
substantial legal costs or damages, or the diversion of management and other
resources, could have a material adverse effect on RCA's business, financial
condition and results of operations.

<PAGE>
    DETERIORATION OF RCA'S RECENT FINANCIAL CONDITION; NONCOMPLIANCE WITH
     CERTAIN COVENANTS; DELINQUENT PROPERTY TAXES.
 
    RCA experienced significant operating and net losses for the fiscal year
ended June 30, 1997. RCA believes that its operating losses of approximately
$9.9 million for the fiscal year ended June 30, 1997 and $8.1 million for the
nine months ended March 31, 1998 were incurred in part due to a deterioration of
RCA's operations as a result of the pendency of and delays associated with the
RCA Merger (including higher than normal turnover), costs associated with the
integration and operation of RCA's recently acquired Virginia and North Carolina
facilities (including significant survey deficiences and costs associated with
temporary staffing and state-appointed management at certain of the Virginia and
North Carolina facilities), and declines in Medicaid rates and occupancy rates
during fiscal year 1997 without a corresponding reduction in operating costs.
 
    At June 30, 1997, RCA had a working capital deficit of approximately $10.5
million compared to a working capital deficit of approximately $1.5 million at
June 30, 1996. During the fiscal year ended June 30, 1997, cash provided by or
used in operating activities was approximately $3.8 million as compared to
approximately $5.3 million for the fiscal year ended June 30, 1996. This
decrease of approximately $8.8 million was primarily due to the net operating
loss of approximately $9.4 million, deferred income taxes of approximately $11.1
million and increases in accounts receivable of approximately $21.0 million,
which were offset by an increase in accounts payable and accrued expenses of
approximately $29.2 million.
 
    RCA has financed the acquisition of several facilities through the issuance
of revenue bonds and similar debt instruments. As of June 30, 1996 and 1997, RCA
was not in compliance with certain of the financial and restrictive covenants
contained in the indentures underlying approximately $43 million of indebtedness
in 1996 and $51 million of indebtedness in 1997, which noncompliance could
result in the acceleration of such indebtedness. These covenants include the
obligation to make monthly payments to bond sinking funds and the failure to
maintain adequate debt service reserves. RCA was also delinquent with regard to
approximately $1.2 million and $0.8 million of property taxes at certain of its
facilities during the fiscal years ended June 30, 1997 and 1996, respectively.
As of March 31, 1998, RCA had total indebtedness outstanding of approximately
$192 million, which indebtedness matures at various times between 1998 and 2026.
 
    There can be no assurance that RCA will not experience continued operating
and net losses and working capital deficits in the future, and unforeseen
expenses, difficulties and complications could result in greater than
anticipated operating losses and working capital deficits or otherwise
materially adversely affect RCA's business, financial condition and results of
operations. Continued operating and net losses could materially adversely affect
RCA's ability to service its indebtedness or secure additional debt financing.
There also can be no assurance that the trustees under RCA's bond indentures
will not demand immediate repayment of the indebtedness thereunder because of
RCA's noncompliance, and in the event of such acceleration, there can be no
assurance that the assets of RCA would be sufficient to repay such indebtedness
in full.
 
    DETERIORATION OF CONTOUR'S RECENT FINANCIAL CONDITION; NONCOMPLIANCE WITH
     CERTAIN COVENANTS.
 
    Contour has experienced significant operating and net losses for the fiscal
year ended June 30, 1997. The net loss of approximately $0.3 million for the
fiscal year ended June 30, 1997 was primarily due to decreases in gross profit
margin historically earned by Contour's bulk medical supplies operations,
increases in operating expenses associated with the acquisition of AmeriDyne
Corporation in March 1996 and Atlantic Medical Supply Company, Inc. in July 1996
and increases in indirect labor expense, occupancy expense, interest expense and
miscellaneous expense.
 
    As of June 30 and March 31, 1998, Contour was not in compliance with certain
financial and other restrictive covenants imposed upon it by its lenders, which
noncompliance could result in the acceleration of the indebtedness owing to such
lenders. These financial covenants include debt to net worth ratio,
 
                                       64
<PAGE>
current ratio and interest coverage ratio maintenance requirments. Contour has
obtained waivers from its lenders in connection with such noncompliance as of
June 30, 1997 and is seeking waivers as of the most recent practicable date. As
of March 31, 1998, Contour had total indebtedness outstanding of approximately
$19 million, which matures at various times between 1998 and 2003.
 
    On December 31, 1997, Sun purchased the Contour Debentures from Renaissance
in a privately negotiated transaction for an aggregate purchase price of $8.4
million in cash. As of June 30, 1997, September 30, 1997 and March 31, 1998,
Contour was not in compliance with certain financial ratios required to be
maintained under the Contour Debentures. On April 2, 1998, Sun agreed to waive
such defaults until 10 business days after the termination of the Contour Merger
Agreement. See "The Contour Merger--Contour Convertible Debentures."
 
    There can be no assurance that Contour will not experience continued
increases in expenses and decreases in gross margins and gross profit in the
future, and other unforeseen expenses, difficulties and complications could
result in greater than anticipated operating losses or otherwise materially
adversely affect Contour's business, financial condition and results of
operations. Continued operating and net losses could also materially adversely
affect Contour's ability to service its indebtedness or secure additional debt
financing. In addition, no assurance can be given that one or more of Contour's
lenders will not demand immediate repayment of their indebtedness, and in the
event of such acceleration, there can be no assurance that the assets of Contour
would be sufficient to repay such indebtedness in full.
 
    CONFLICTS OF INTEREST AND RELATED PARTY TRANSACTIONS INVOLVING RCA.
 
    Certain of RCA's executive officers and directors are also officers and
directors of certain companies affiliated with RCA. In particular, Christopher
F. Brogdon and Edward E. Lane are officers, directors or owners of Winter Haven
Homes, Inc. ("WHH") and Southeastern Cottages, Inc. ("SCI"), which own or
control an aggregate of three facilities for which a subsidiary or RCA provides
management services. In addition, Mr. Brogdon and Mr. Lane serve as officers
and/or directors of Chamber Health Care Society, Inc. ("Chamber"), Gordon Jensen
Health Care Associates, Inc. ("Gordon Jensen") and National Assistance Bureau,
Inc. ("NAB"), nonprofit corporations which own or control an aggregate of four
facilities for which RCA provides management services. Neither RCA nor its
management has an economic interest in the nonprofit corporations for which RCA
provides management services other than the management fees RCA receives. Mr.
Brogdon is also a significant stockholder, a director and chairman of the board
of NewCare Health Corporation ("NewCare"), a publicly held company which
provides senior residential care services, primarily as operator of long-term
care facilities, in the southeastern United States. Harlen F. Matthews, a
director of RCA, is also a director of NewCare. See "Other Information Regarding
RCA--Directors and Executive Officers."
 
    Messrs. Brogdon and Lane may have conflicts of interest in allocating their
time and effort between RCA and such affiliated companies, as well as in
connection with transactions between RCA and such affiliated companies. Such
conflicts of interest could have an adverse effect on RCA's operations.
 
    In addition to providing management services to affiliated companies, RCA
has engaged in a number of other transactions with affiliated entities,
including the payment of financial advisory fees to a company owned by Connie B.
Brogdon, the wife of Mr. Brogdon, payments to an affiliated company to obtain
rights to leases held by it and the guarantee of certain indebtedness of an
affiliated non-profit corporation and the guarantee of certain indebtedness of
an affiliated for profit corporation. See "Certain Relationships and Related
Transactions," included in RCA's Annual Report on Form 10-K for the year ended
June 30, 1997, incorporated by reference herein.
 
    ADVANCES BY RCA TO FACILITIES CONTROLLED BY AFFILIATES.
 
    A subsidiary of RCA provides management services to four facilities that are
owned or controlled by affiliates of RCA and certain affiliated for-profit and
nonprofit corporations. In connection with such
 
                                       65
<PAGE>
management services, RCA provides cash management services and has advanced
working capital to such facilities. At March 31, 1998, the aggregate amount due
from affiliates of RCA was $11,897,266. Management of RCA believes that the
total indebtedness on these properties is less than their total market value. If
for any reason RCA is unable to collect the amounts advanced, RCA could incur
substantial losses.
 
    CONTOUR'S DEPENDENCE ON RCA.
 
    During the fiscal years ended June 30, 1997 and June 30, 1996, Contour
generated a significant amount of its sales and revenues from RCA. Contour sold
approximately $7.8 million and $5.5 million, respectively, in products
(primarily bulk medical supplies) to facilities owned, leased or managed by RCA.
Such sales represented 14% of total sales for the fiscal year ended June 30,
1997, and 37% of total sales for the fiscal year ended June 30, 1996. No other
individual customer represented more than 10% of total sales during such
periods. For the fiscal year ended June 30, 1997, after excluding the revenues
generated by sales to RCA, the next nine largest customers cumulatively
represented approximately 15% of Contour's total revenues. Further, Contour
generated a significant portion of its accounts receivable from RCA. As of March
31, 1998, Contour had accounts receivable from RCA of approximately $6.5
million. Although Contour's customer base has grown as its sales volume has
increased, it is currently still significantly dependent on continued purchases
of Contour's products by RCA. Contour may continue to rely on RCA as a source of
debt financing. In addition, RCA's financial condition and results of operations
have deteriorated in the periods subsequent to the execution of the RCA Merger
Agreement on February 17, 1987. See "--Risk Factors Concerning RCA and
Contour--Deterioration of RCA's Financial Condition." The loss of RCA's
business, or the inability to secure financing from RCA, could materially
adversely affect Contour's business, financial condition and results of
operations.

N.E., Albuquerque, New Mexico, 87109, on June 26, 1998, at 10:00 a.m., local
time, and at any adjournments or postponements thereof, for the purposes set

of Sun.
 
    MATTERS TO BE CONSIDERED.  At the Sun Special Meeting, stockholders of

to consider and vote upon proposals (i) to approve and adopt the RCA Merger
Agreement and to approve the RCA Merger and the issuance of Sun Common Stock and
Sun Preferred Stock pursuant thereto; (ii) to approve and adopt the Contour
Merger Agreement and to approve the Contour Merger and the issuance of Sun

Certificate of Incorporation to increase the number of authorized shares of Sun
Common Stock; and (iv) to transact such other business as may properly come
before the Sun Special Meeting or any adjournments or postponements thereof.
 
    BOARD OF DIRECTORS' RECOMMENDATIONS.  THE BOARD OF DIRECTORS OF SUN HAS
DETERMINED THAT THE RCA MERGER AND THE CONTOUR MERGER ARE FAIR TO, AND IN THE
BEST INTERESTS OF, THE STOCKHOLDERS OF SUN AND HAS THEREFORE UNANIMOUSLY
APPROVED AND ADOPTED THE RCA MERGER AGREEMENT AND APPROVED THE RCA MERGER AND
UNANIMOUSLY APPROVED AND ADOPTED THE CONTOUR MERGER AGREEMENT AND APPROVED THE
CONTOUR MERGER, AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF SUN VOTE FOR
(I) THE APPROVAL AND ADOPTION OF THE RCA MERGER AGREEMENT AND APPROVAL OF THE
RCA MERGER AND THE ISSUANCE OF SUN COMMON STOCK AND SUN PREFERRED STOCK PURSUANT
THERETO AND (II) THE APPROVAL AND ADOPTION OF THE CONTOUR MERGER AGREEMENT AND
APPROVAL OF THE CONTOUR MERGER AND THE ISSUANCE OF SUN COMMON STOCK PURSUANT
THERETO. THE BOARD OF DIRECTORS OF SUN HAS ALSO UNANIMOUSLY APPROVED AND
RECOMMENDS THAT THE STOCKHOLDERS OF SUN VOTE FOR THE APPROVAL OF THE AMENDMENT
TO SUN'S CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED
SHARES OF SUN COMMON STOCK.
 
    SUN RECORD DATE.  The board of directors of Sun fixed May 1, 1998 as the
record date for determination of holders of Sun Common Stock entitled to notice
of and to vote at the Sun Special Meeting. As of the close of business on the
Sun Record Date, 49,619,442 shares of Sun Common Stock were outstanding, held by
approximately 4,993 holders of record. Only holders of record of Sun Common
Stock as of the close of business on the Sun Record Date are entitled to notice
of and to vote at the Sun Special Meeting and any adjournments or postponements
thereof.
 
    VOTING; VOTE REQUIRED.  Each holder of record of Sun Common Stock on the Sun
Record Date is entitled to cast one vote per share of Sun Common Stock held
thereby on the Sun Record Date, exercisable in person or by properly executed
proxy, on each matter properly submitted for the vote of the stockholders of Sun
at the Sun Special Meeting. A majority of the shares of Sun Common Stock
entitled to vote at the Sun Special Meeting will constitute a quorum for the
transaction of business at the Sun Special Meeting.
 
    The approval of the RCA Merger Agreement and the RCA Merger and the issuance
of shares of Sun Common Stock and Sun Preferred Stock pursuant to the RCA
Merger, and the approval of the Contour Merger Agreement and the Contour Merger
and the issuance of shares of Sun Common Stock pursuant to the Contour Merger,
will each require the affirmative vote of a majority of the shares of Sun Common
Stock present in person or represented by properly executed proxy at the Sun
Special Meeting. The approval of the amendment to Sun's Certificate of
Incorporation will require the affirmative vote of a majority of the outstanding
shares of Sun Common Stock.
 
                                       67
<PAGE>
    Shares of Sun Common Stock that are voted "FOR," "AGAINST" or "WITHHELD" at
the Sun Special Meeting will be treated as being present at such meeting for
purposes of establishing a quorum and will also be treated as votes eligible to
be cast by the Sun Common Stock present in person or represented by proxy at the
Sun Special Meeting and entitled to vote on the subject matter. Abstentions will
be counted for purposes of determining both the presence or absence of a quorum
for the transaction of business and the total number of votes cast with respect
to a particular matter. Broker non-votes (i.e., shares identified as held by
brokers or nominees as to which instructions have not been received from the
beneficial owners or persons entitled to vote that the broker or nominee does
not have discretionary power to vote on a particular matter) will be counted for
purposes of determining the presence or absence of a quorum for the transaction
of business, but will not be counted for purposes of determining the number of
votes cast with respect to the particular proposal on which the broker has
expressly not voted. Broker non-votes with respect to proposals set forth in
this Joint Proxy Statement/Prospectus/Information Statement will therefore not
be considered votes cast and, accordingly, will not affect the determination as
to whether a majority of votes cast has been obtained with respect to a
particular matter, other than with respect to the approval of the amendment to
Sun's Certificate of Incorporation, which approval will require the affirmative
vote of a majority of the outstanding shares of Sun Common Stock.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the Sun Record Date, directors and executive officers of
Sun and their respective affiliates may be deemed to be the beneficial owners of
shares of Sun Common Stock representing approximately 15.5% of the outstanding
voting power of Sun. See "Other Information Regarding Sun--Equity Ownership of
Management" and "--Equity Ownership of Principal Stockholders." Each of the
directors and executive officers of Sun has indicated that such person intends
to vote or direct the vote of all the shares of Sun Common Stock over which such
person has voting control in favor of the approval and adoption of the RCA
Merger Agreement and approval of the RCA Merger and the issuance of shares of
Sun Common Stock and Sun Preferred Stock pursuant thereto, the approval and
adoption of the Contour Merger Agreement and approval of the Contour Merger and
the issuance of shares of Sun Common Stock pursuant thereto, and the approval of
the amendment to Sun's Certificate of Incorporation.
 
    Eligible participants in certain of Sun's stock-based benefit plans are
entitled to instruct the trustee of the Sun Healthcare Group, Inc. Grantor Stock
Trust (the "GSOP Trust") on how to vote a designated percentage of the shares of
Sun Common Stock held by the GSOP Trust. The percentage allocated to each
eligible participant is solely for the purpose of voting the shares owned by the
GSOP Trust. Such participants will receive separate voting instruction cards to
direct the trustee, on a confidential basis, to vote the shares. If the trustee
receives an instruction card on a timely basis from a participant, it will vote
the participant's allocated shares as the participant instructs. If a
participant signs and timely returns an instruction card without indicating a
vote, the trustee will vote that participant's allocated shares in accordance
with the recommendations of the board of directors. Allocations are based on the
number of eligible participants who provide voting instructions to the trustee
on a timely basis. All shares held by the GSOP Trust will be voted by eligible
participants.
 
THE RCA SPECIAL MEETING
 
    GENERAL.  This Joint Proxy Statement/Prospectus/Information Statement is
also being furnished to shareholders of RCA in connection with the solicitation
of proxies by the board of directors of RCA for use at the RCA Special Meeting
to be held at RCA's principal offices located at 6000 Lake Forrest Drive, Suite
200, Atlanta, Georgia 30328, on June 26, 1998, at 8:30 a.m., local time, and at
any adjournments or postponements thereof, for the purposes set forth herein and
in the accompanying notice of special meeting of shareholders of RCA.
 
    MATTERS TO BE CONSIDERED.  At the RCA Special Meeting, shareholders of
record of RCA as of the close of business on the RCA Record Date will be asked
to consider and vote upon proposals (i) to approve and adopt the RCA Merger
Agreement and to approve the RCA Merger; and (ii) to transact such
 
                                       68
<PAGE>
other business as may properly come before the RCA Special Meeting or any
adjournments or postponements thereof.
 
    BOARD OF DIRECTORS' RECOMMENDATIONS.  THE BOARD OF DIRECTORS OF RCA HAS
DETERMINED THAT THE RCA MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE
SHAREHOLDERS OF RCA AND HAS THEREFORE UNANIMOUSLY APPROVED AND ADOPTED THE RCA
MERGER AGREEMENT AND APPROVED THE RCA MERGER, AND UNANIMOUSLY RECOMMENDS THAT
THE SHAREHOLDERS OF RCA VOTE FOR THE APPROVAL AND ADOPTION OF THE RCA MERGER
AGREEMENT AND APPROVAL OF THE RCA MERGER. Shareholders of RCA, in evaluating
whether to approve and adopt the RCA Merger Agreement and approve the RCA
Merger, should consider the fact that the board of directors of RCA did not
engage a financial advisor or obtain a fairness opinion in connection with its
decision to make such recommendation. See "Risk Factors--Risk Factors Concerning
RCA and Contour--Lack of a Fairness Opinion in Connection with the RCA Merger"
and "The RCA Merger--RCA's Reasons for the RCA Merger; Recommendation of RCA's
Board of Directors."
 
    RCA RECORD DATE.  The board of directors of RCA fixed May 12, 1998 as the
record date for determination of holders of RCA Capital Stock entitled to notice
of and to vote at the RCA Special Meeting. As of the close of business on the
RCA Record Date, (i) 14,798,525 shares of RCA Common Stock were outstanding,
held by approximately 269 holders of record; (ii) 120,000 shares of RCA Series
AA Preferred Stock were outstanding, held by approximately seven holders of
record; and (iii) 298,334 shares of RCA Series F Preferred Stock were
outstanding, held by approximately three holders of record. Only holders of
record of RCA Capital Stock as of the close of business on the RCA Record Date
are entitled to notice of and to vote at the RCA Special Meeting and any
adjournments or postponements thereof.
 
    VOTING; VOTE REQUIRED.  Each holder of record of RCA Capital Stock on the
RCA Record Date is entitled to cast one vote for each share of RCA Common Stock
held thereby, or into which shares of RCA Series AA Preferred Stock or RCA
Series F Preferred Stock held thereby are convertible (110,250 shares of RCA
Common Stock, in the case of the RCA Series AA Preferred Stock, and 499,621
shares of RCA Common Stock, in the case of the RCA Series F Preferred Stock), on
the RCA Record Date, exercisable in person or by properly executed proxy, on
each matter properly submitted for the vote of the shareholders of RCA at the
RCA Special Meeting. A majority of the shares of RCA Capital Stock entitled
(with the RCA Series AA Preferred Stock and RCA Series F Preferred Stock being
counted on an as-converted basis) to vote at the RCA Special Meeting will
constitute a quorum for the transaction of business at the RCA Special Meeting.
 
    The approval of the RCA Merger Agreement and the RCA Merger will require the
affirmative vote of a majority of the outstanding shares of RCA Capital Stock
(with the RCA Series AA Preferred Stock and RCA Series F Preferred Stock voting
on an as-converted basis), voting together as a single class. Concurrently with
the execution of the RCA Merger Agreement, Sun entered into the RCA Stock Option
Agreement with Christopher F. Brogdon, Connie B. Brogdon, Edward E. Lane,
Darrell C. Tucker and Winter Haven Homes Inc., collectively owners as of such
date of approximately 36% of the outstanding shares of RCA Capital Stock,
pursuant to which each such stockholder agreed to vote, and granted to Sun an
irrevocable proxy to vote, all voting securities of RCA held by such
stockholders in favor of approval of the RCA Merger Agreement and the RCA
Merger. See "The RCA Stockholders Stock Option and Proxy Agreement."
 
    Shares of RCA Capital Stock that are voted "FOR," "AGAINST" or "WITHHELD" at
the RCA Special Meeting will be treated as being present at such meeting for
purposes of establishing a quorum and will also be treated as votes eligible to
be cast by the RCA Capital Stock present in person or represented by proxy at
the RCA Special Meeting and entitled to vote on the subject matter. Abstentions
will be counted for purposes of determining both the presence or absence of a
quorum for the transaction of business and the total number of votes cast with
respect to a particular matter. Broker non-votes will be counted for purposes of
determining the presence or absence of a quorum for the transaction of business,
 
                                       69
<PAGE>
but will not be counted for purposes of determining the number of votes cast
with respect to the particular proposal on which the broker has expressly not
voted. Abstention and broker non-votes will have the same effect as a vote
against the approval of the RCA Merger Agreement and the RCA Merger which
approval will require the affirmative vote of a majority of the outstanding
shares of RCA Capital Stock (with the RCA Series AA Preferred Stock and RCA
Series F Preferred Stock voting on an as-converted basis), voting together as a
single class.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the RCA Record Date, directors and executive officers of
RCA and their respective affiliates may be deemed to be the beneficial owners of
shares of RCA Capital Stock representing approximately 31.9% of the outstanding
voting power of RCA. See "Other Information Regarding RCA--Equity Ownership of
Principal Shareholders and Management." Each of the directors and executive
officers of RCA has indicated that such person intends to vote or direct the
vote of all the shares of RCA Capital Stock over which such person has voting
control in favor of the RCA Merger Agreement and the RCA Merger. In addition,
concurrently with the execution of the RCA Merger Agreement, Sun and the owners
as of such date of approximately 36% of the outstanding shares or RCA Capital
Stock entered into the RCA Stock Option Agreement, pursuant to which each such
stockholder granted to Sun the right to vote all of the voting securities of RCA
held by such stockholders in favor of the RCA Merger Agreement and the RCA
Merger. See "The RCA Stockholders' Stock and Proxy Option Agreement."

    GENERAL.  This Joint Proxy Statement/Prospectus/Information Statement is
also being furnished to stockholders of Contour in connection with the Contour
Special Meeting to be held at the principal offices of RCA, located at 6000 Lake
Forrest Drive, Suite 200, Atlanta, Georgia 30328, on June 18, 1998, at 10:00
a.m., local time, and at any adjournments or postponements thereof, for the
purposes set forth herein and in the accompanying notice of special meeting of
stockholders of Contour.
 
    MATTERS TO BE CONSIDERED.  At the Contour Special Meeting, stockholders of
record of Contour as of the close of business on the Contour Record Date will be
asked to consider and vote upon proposals (i) to approve and adopt the Contour
Merger Agreement and to approve the Contour Merger; and (ii) to transact such
other business as may properly come before the Contour Special Meeting or any
adjournments or postponements thereof.
 
    BOARD OF DIRECTORS' RECOMMENDATIONS.  THE BOARD OF DIRECTORS OF CONTOUR HAS
DETERMINED THAT THE CONTOUR MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, THE
STOCKHOLDERS OF CONTOUR AND HAS THEREFORE UNANIMOUSLY APPROVED AND ADOPTED THE
CONTOUR MERGER AGREEMENT AND APPROVED THE CONTOUR MERGER, AND UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF CONTOUR VOTE FOR THE APPROVAL AND ADOPTION
OF THE CONTOUR MERGER AGREEMENT AND APPROVAL OF THE CONTOUR MERGER.
 
    CONTOUR RECORD DATE.  The board of directors of Contour has fixed May 1,
1998 as the record date for determination of holders of Contour Capital Stock
entitled to notice of and to vote at the Contour Special Meeting. As of the
close of business on the Contour Record Date, (i) 8,309,081 shares of Contour
Common Stock were outstanding, held by approximately 104 holders of record; and
(ii) 120,000 shares of Contour Preferred Stock were outstanding, held by
approximately six holders of record. Only holders of record of Contour Capital
Stock as of the close of business on the Contour Record Date are entitled to
notice of and to vote at the Contour Special Meeting and any adjournments or
postponements thereof.
 
    VOTING; VOTE REQUIRED.  Each holder of record of Contour Capital Stock on
the Contour Record Date is entitled to cast one vote for each share of Contour
Common Stock held thereby, or into which shares of Contour Preferred Stock held
thereby are convertible (126,000 shares of Contour Common Stock), on the Contour
Record Date, exercisable in person on each matter properly submitted for the
vote of the stockholders of Contour at the Contour Special Meeting. A majority
of the shares of Contour Capital
 
                                       70
<PAGE>
Stock (with the Contour Preferred Stock being counted on an as-converted basis)
entitled to vote at the Contour Special Meeting will constitute a quorum for the
transaction of business at the Contour Special Meeting.
 
    The approval of the Contour Merger Agreement and the Contour Merger will
require the affirmative vote of a majority of the outstanding shares of Contour
Capital Stock (with the Contour Preferred Stock voting on an as-converted
basis), voting together as a single class. Concurrently with the execution of
the Contour Merger Agreement, Sun entered into the Contour Stock Option
Agreement with RCA, pursuant to which RCA agreed to vote, and granted to Sun an
irrevocable proxy to vote all of the 5,222,003 shares of Contour Common Stock
and 85,000 shares of Contour Preferred Stock owned by RCA in favor of the
Contour Merger Agreement and the Contour Merger. See "The Contour Stockholder
Stock Option and Proxy Agreement." AS A RESULT, SUN HAS THE RIGHT TO VOTE AT THE
CONTOUR SPECIAL MEETING SUFFICIENT SHARES TO APPROVE THE CONTOUR MERGER
AGREEMENT WITHOUT THE AFFIRMATIVE VOTE OF ANY OTHER STOCKHOLDER, THEREBY
ASSURING THE APPROVAL OF THE CONTOUR MERGER AGREEMENT AND THE CONTOUR MERGER.
 
    Shares of Contour Capital Stock that are voted "FOR," "AGAINST" or
"WITHHELD" at the Contour Special Meeting will be treated as being present at
such meeting for purposes of establishing a quorum and will also be treated as
votes eligible to be cast by the Contour Capital Stock present in person at the
Contour Special Meeting and entitled to vote on the subject matter. Abstentions
will be counted for purposes of determining both the presence or absence of a
quorum for the transaction of business and the total number of votes cast with
respect to a particular matter. Abstentions will have the same effect as a vote
against the approval of the Contour Merger Agreement and the Contour Merger,
which approval will require the affirmative vote of a majority of the
outstanding shares of Contour Capital Stock (with the Contour Preferred Stock
voting on an as-converted basis), voting together as a single class.
 
    SECURITY OWNERSHIP BY CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.  As of the
close of business on the Contour Record Date, directors and executive officers
of Contour and their respective affiliates, including RCA, may be deemed to be
the beneficial owners of shares of Contour Capital Stock representing
approximately 66.7 percent of the outstanding voting power of Contour. See
"Other Information Regarding Contour--Equity Ownership of Principal Stockholders
and Management." Each of the directors and executive officers of Contour has
indicated that such person intends to vote or direct the vote of all the shares
of Contour Capital Stock over which such person has voting control in favor of
the Contour Merger Agreement and the Contour Merger. In addition, concurrently

to vote all of the 5,222,003 shares of Contour Common Stock and 85,000 shares of
Contour Preferred Stock owned by RCA in favor of the Contour Merger Agreement
and the Contour Merger. See "The Contour Stockholder Stock Option and Proxy
Agreement." AS A RESULT, SUN HAS THE RIGHT TO VOTE AT THE CONTOUR SPECIAL
MEETING SUFFICIENT SHARES TO APPROVE THE CONTOUR MERGER AGREEMENT WITHOUT THE
AFFIRMATIVE VOTE OF ANY OTHER STOCKHOLDER, THEREBY ASSURING THE APPROVAL OF THE
CONTOUR MERGER AGREEMENT AND THE CONTOUR MERGER.

furnished to holders of Sun Common Stock and holders of RCA Capital Stock in
connection with the solicitation of proxies by and on behalf of the boards of
directors of Sun and RCA for use at the Sun Special Meeting and the RCA Special
Meeting, respectively. All shares of Sun Common Stock and all shares of RCA

Meeting or the RCA Special Meeting, as the case may be, by properly executed
proxies received prior to or at such meeting and not duly and timely revoked,

shares of Sun Common Stock and Sun Preferred Stock pursuant thereto, (B) the
approval
 
                                       71

Sun Special Meeting or the RCA Special Meeting or any adjournments or
postponements thereof, including, among other things, consideration of a motion
to adjourn or postpone either such 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 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

the vote at the Sun Special Meeting or the RCA Special Meeting, as the case may
be, 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 Sun or RCA, as the case may be, before the taking of the
vote at the Sun Special Meeting or the RCA Special Meeting, as the case may be,
or (iii) attending the Sun Special Meeting or the RCA Special Meeting, as the
case may be, and voting in person (although attendance at the Sun Special
Meeting or the RCA Special Meeting, as the case may be, 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, in the case of holders of
Sun Common Stock, to Sun Healthcare Group, Inc., at 101 Sun Avenue, N.E.,
Albuquerque, New Mexico 87109, Attention: Secretary, and in the case of holders

by directors, officers and employees of Sun and RCA in person or by telephone,
telegram or other means of communication. Such directors, officers and employees

solicitations of proxies from brokers, nominees, institutions and individuals.
As compensation for acting as solicitor in connection with the RCA Merger and
the Contour Merger, Morrow will be paid a fee of $10,000 and will also be

nominees and fiduciaries for reasonable expenses incurred in connection
therewith.

                                 THE RCA MERGER
 
GENERAL
 
    The RCA Merger Agreement provides that RCA Merger Sub will be merged with
and into RCA. As a result of the RCA Merger, the separate corporate existence of
RCA Merger Sub will cease and RCA will continue as the surviving corporation of
the RCA Merger (the "Surviving RCA Corporation") and will become a direct
wholly-owned subsidiary of Sun. The RCA Merger will take place as promptly as
practicable after the adoption and approval of the RCA Merger Agreement and the
approval of the RCA Merger by the stockholders of Sun and the shareholders of
RCA, and the satisfaction or waiver of the other conditions to the RCA Merger
set forth in the RCA Merger Agreement. See "The RCA Merger Agreement." It is
expected that the RCA Merger will occur promptly after the consummation of the
Contour Merger.
 
CONVERSION OF RCA CAPITAL STOCK
 
    At the RCA Effective Time, by virtue of the RCA Merger and without any
action on the part of Sun, RCA Merger Sub, RCA or the holders of RCA Capital
Stock, each share of RCA Capital Stock issued and outstanding immediately prior
to the RCA Effective Time (other than any shares of RCA Capital Stock to be
canceled as described below and any dissenting shares) and all rights in respect
thereof will forthwith cease to exist and will be converted into and become
exchangeable for the number of shares of Sun Common Stock (and associated
Preferred Share Purchase Rights) or Sun Preferred Stock, as the case may be,
described below.
 
    RCA COMMON STOCK.  Pursuant to the RCA Merger Agreement, each outstanding
share of RCA Common Stock will be converted into the number of shares of Sun
Common Stock equal to the lower of (i) the number of shares of Sun Common Stock
equal to the quotient of $10.00 divided by the average of the last reported
sales prices of one share of Sun Common Stock on The New York Stock Exchange
(the "NYSE") during the period of the 20 most recent trading days ending five
business days before the RCA Effective Time (the "Sun Market Price") (unless the
Sun Market Price exceeds $24.20 per share, in which case each outstanding share
of RCA Common Stock will be converted into 0.413 shares of Sun Common Stock, or
unless the Sun Market Price is less than $19.80 per share, in which case each
outstanding share of RCA Common Stock will be converted into 0.505 shares of Sun
Common Stock) (such number of shares being referred to as the "Pre-Adjustment
Common Exchange Ratio"), and (ii) in the event that the RCA Series AA Exchange
Ratio (as defined below under "--RCA Series AA Preferred Stock") is greater than
0.714, the Pre-Adjustment Common Exchange Ratio multiplied by the Adjustment
Amount (as defined below) (the lower of such numbers being the "RCA Common
Exchange Ratio").
 
    For purposes of the RCA Merger Agreement, the "Adjustment Amount" means the
quotient of (x) (A) the aggregate number of shares of Sun Common Stock issuable
upon conversion of RCA Common Stock, pursuant to the RCA Merger, before giving
effect to clause (ii) in the preceding paragraph, minus (B) the product of (1)
the aggregate number of shares of RCA Series AA Preferred Stock issued and
outstanding immediately prior to the RCA Effective Time multiplied by (2) the
RCA Series AA Exchange Ratio minus 0.714; divided by (y) the aggregate number of
shares of Sun Common Stock issuable upon conversion of RCA Common Stock,
pursuant to the RCA Merger, before giving effect to clause (ii) in the preceding
paragraph.
 
    In general, if the market price of the Sun Common Stock is lower at the RCA
Effective Time than on February 14, 1997, when the market price of the Sun
Common Stock was $14.00 per share, the RCA Common Exchange Ratio will be
adjusted downward by the Adjustment Amount. For example, if the RCA Merger had
been consummated on May 20, 1998, when the Sun Market Price would have been
$17.725, the RCA Common Exchange Ratio would not have been adjusted. However, if
on such date the Sun Market Price was $10.00, and the holders of the RCA Series
AA Preferred Stock had elected prior to the RCA Effective Time to receive the
number of shares of Sun Common Stock issuable upon conversion of
 
                                       73
<PAGE>
the RCA Series AA Preferred Stock at the RCA Effective Time pursuant to the RCA
Merger Agreement, then the RCA Common Exchange Ratio would have been 0.502.
 
    RCA SERIES AA PREFERRED STOCK.  Each outstanding share of RCA Series AA
Preferred Stock will be converted into the number of shares of Sun Common Stock
equal to the quotient of $10.00 divided by the Sun Market Price (the "RCA Series
AA Exchange Ratio" and, together with the RCA Common Exchange Ratio, the "RCA
Exchange Ratios").
 
    RCA SERIES F PREFERRED STOCK.  Each outstanding share of RCA Series F
Preferred Stock will be converted into one share of Sun Preferred Stock, which
shares of Sun Preferred Stock shall thereafter be convertible into the number of
shares of Sun Common Stock that such shares of RCA Series F Preferred Stock
would have been converted into if converted immediately prior to the RCA
Effective Time. If the RCA Effective Time had occured on May 20, 1998, each
share of Sun Preferred Stock into which the RCA Series F Preferred Stock will be
converted will be convertible into 0.857 shares of Sun Common Stock. The Sun
Preferred Stock will provide voting rights on an as-converted basis, and will be
substantially similar in all other respects to the RCA Series F Preferred Stock.
See "Description of Sun Capital Stock--Series B Convertible Preferred Stock."
 
    The shares of RCA Series F Preferred Stock are convertible into shares of
RCA Common Stock at a conversion price equal to the lesser of (a) $7.638125 or
(b) 85% of the average closing bid price of the RCA Common Stock for the five
trading days prior to the date of conversion. At the time of conversion, the
holder is also entitled to additional shares of RCA Common Stock equal to $10.00
per share of RCA Series F Preferred Stock converted multiplied by 8% per annum
from the date of issuance (September 25, 1996) divided by the applicable
conversion price.
 
    RCA TREASURY STOCK.  Each share of RCA Capital Stock held in the treasury of
RCA and each share of RCA Capital Stock owned by Sun or any direct or indirect
wholly-owned subsidiary of Sun or of RCA immediately prior to the RCA Effective
Time will be canceled and extinguished without any conversion thereof and no
payment will be made with respect thereto.
 
    NO FRACTIONAL SHARES.  No fractional share certificates for Sun Common Stock
will be issued upon the surrender for exchange of certificates evidencing shares
of RCA Capital Stock. In lieu thereof, the Exchange Agent or Sun, as the case
may be, will pay each holder of RCA Capital Stock an amount in cash calculated
as provided in the RCA Merger Agreement.
 
    OPTIONS AND WARRANTS.  At the RCA Effective Time, each option or warrant
granted by RCA to purchase shares of RCA Common Stock (each, an "RCA Stock
Option") which is outstanding and unexercised immediately prior to the Effective
Time will be assumed by Sun and converted into an option or warrant to purchase
shares of Sun Common Stock in such number and at such exercise price as follows
and otherwise have the same terms and conditions as in effect immediately prior
to the RCA Effective Time: (i) the number of shares of Sun Common Stock to be
subject to the new option or warrant will be equal to the product of (A) the
number of shares of RCA Common Stock subject to the original option or warrant
and (B) the RCA Common Exchange Ratio; (ii) the exercise price per share of Sun
Common Stock under the new option or warrant will be equal to the quotient of
(A) the exercise price per share of RCA Common Stock under the original option
or warrant divided by (B) the RCA Common Exchange Ratio; and (iii) upon each
exercise of options or warrants by a holder thereof, the aggregate number of
shares of Sun Common Stock deliverable upon such exercise shall be rounded down
to the nearest whole share and the aggregate exercise price shall be rounded up
to the nearest cent. Under the RCA Merger Agreement, Sun has agreed to file a
registration statement on Form S-8 with respect to the shares of Sun Common
Stock subject to the Retirement Care Associates, Inc. 1993 Stock Option Plan
following the RCA Effective Time in order for such shares of Sun Common Stock to
be sold without restriction. The RCA Merger Agreement does not require Sun to
register the shares of Sun Common Stock issuable upon exercise of any warrants
assumed by Sun in the RCA Merger.
 
                                       74

    CERTAIN ADJUSTMENTS.  If, between the date of the RCA Merger Agreement and
the RCA Effective Time, the outstanding shares of RCA Capital Stock or Sun
Common Stock are changed into a different number of shares by reason of any
reclassification, recapitalization, split-up, combination or exchange of shares,
or any dividend payable in stock or other securities is declared thereon with a
record date within such period or the number of shares of RCA Capital Stock on a
fully diluted basis is in excess of 15,933,284 shares (but excluding options
permitted to be issued pursuant to the RCA Merger Agreement), the RCA Exchange
Ratios will be adjusted accordingly to provide the holder of RCA Capital Stock
the same economic effect as contemplated by the RCA Merger Agreement prior to
such reclassification, recapitalization, split-up, combination, exchange,
dividend or increase.
 
BACKGROUND OF THE MERGERS
 
    The RCA board of directors has from time to time discussed the advisability
of RCA engaging in a strategic combination with another company involved in the
long-term care industry. As part of this process, in October 1996, the RCA board
authorized management to identify selected publicly traded long-term care
companies to determine their interest in engaging in preliminary discussions
with RCA regarding a possible business combination. With the assistance of RCA's
then-financial advisor, National Westminster Bank plc, New York Branch
("NatWest"), management evaluated potential merger candidates and concluded that
a business combination with Sun presented the greatest strategic and financial
opportunities for RCA and its shareholders. This conclusion was based primarily
on the geographic complementarity of the two companies and because of the
opportunity that Sun would have to provide higher margin ancillary services in
RCA's facilities, which together likely would allow Sun to attribute a higher
value to RCA than other companies in the industry.
 
    On October 14, 1996, a representative of NatWest, which was engaged at such
time as RCA's financial advisor, contacted Andrew L. Turner, Sun's President,
Chief Executive Officer and Chairman of the Board, to determine Sun's interest
in meeting to consider a possible business combination with RCA. Mr. Turner
returned the call the following day, at which time NatWest introduced RCA as a
possible acquisition candidate by Sun. On October 25, 1996, Mr. Turner met in
Baltimore, Maryland, with Christopher F. Brogdon, RCA's President, Chief
Executive Officer and Chairman of the Board, Philip M. Rees, General Counsel of
RCA, and two representatives of NatWest. On the basis of this meeting, the
parties agreed to further investigate a possible stock merger transaction based
on the potential strategic opportunities each of Sun and RCA perceived,
including the geographic complementarity of the two companies and opportunity
for Sun to provide higher-margin ancillary services to RCA's facilities.
 
    During the course of the parties' discussions on October 25, 1996, Messrs.
Brogdon and Rees also discussed with Mr. Turner RCA's ownership of Contour. Mr.
Turner asked Messrs. Brogdon and Rees for more information about Contour and
expressed an interest in exploring a business combination with Contour through a
separate stock or cash merger transaction.
 
    On November 2, 1996, a representative of NatWest contacted Warren McInteer,
Sun's Vice President of Mergers & Acquisitions, for the purpose of discussing
synergies that might result from a combination of Sun and RCA, including the
geographic complementarity of the two companies and the opportunity for Sun to
provide higher-margin ancillary services in RCA's facilities. On November 12,
1996, Sun signed a confidentiality agreement with RCA covering information
pertaining to RCA and its subsidiaries, including Contour, provided by RCA to
Sun. After executing the confidentiality agreement, Sun began to receive
information and conduct due diligence pertaining to RCA and Contour.
 
    On December 11, 1996, senior members of management of RCA, including Messrs.
Brogdon and Rees, and Sun, including Messrs. Turner and McInteer and Robert D.
Woltil, Sun's Senior Vice President for Financial Services and Chief Financial
Officer, together with a representative of NatWest, met at Sun's headquarters in
Albuquerque, New Mexico, to conduct due diligence and to discuss generally the
business of the two companies and the possibility of a business combination.
 
                                       75
<PAGE>
    On December 20, 1996, RCA executed a confidentiality agreement covering
information provided by Sun to RCA, and thereafter RCA began a due diligence
investigation of Sun on its own behalf and on behalf of Contour. Sun
subsequently engaged J.P. Morgan to act as its financial advisor, including
assisting in the due diligence process. Concurrent with the due diligence
process, which lasted approximately two months, representatives of the parties
(principally (i) Messrs. Turner, McInteer, Woltil, as well as representatives of
J.P. Morgan and Sun's legal advisors, on behalf of Sun, (ii) Messrs. Brogdon and
Rees and Edward E. Lane, RCA's Secretary, and Darrell C. Tucker, RCA's
Treasurer, as well as representatives of NatWest and RCA's legal advisors, on
behalf of RCA, and (iii) Messrs. Brogdon, Rees, Lane and Tucker, as well as
Contour's legal advisors, on behalf of Contour) began conducting negotiations
regarding the terms of the proposed mergers. Management of RCA and Contour
advised the members of each company's respective boards from time to time of the
status of RCA's and Contour's due diligence and the status of their negotiations
with Sun.
 
    On January 10, 1997, Sun loaned RCA $9,750,000 (the "Sun Loan") in order to
enable RCA to cause the repayment of certain indebtedness incurred by Contour in
connection with Contour's acquisition of Atlantic Medical Supply Company, Inc.
on August 6, 1996 (the "Atlantic Note"). The Atlantic Note, which was due on
January 10, 1997, provided that, if an event of default occurred or continued,
the Atlantic Note would have been convertible, at the option of the holder, into
shares of RCA Common Stock at a 15% discount to the market price. The Sun Loan
was made because Sun and RCA desired to prevent the Atlantic Note from going
into default while the parties were engaged in discussions regarding the RCA
Merger. RCA loaned the proceeds it received from Sun to Contour (the "RCA Loan")
and simultaneously converted the RCA Loan into 1,950,000 shares of Contour
Common Stock. Contour then satisfied the Atlantic Note with the funds it
received from the RCA Loan. In addition, Contour agreed to pay RCA a fee of
$500,000 in consideration for RCA's guarantee of the Atlantic Note, which was
satisfied by Contour's issuance of an additional 100,000 shares of Contour
Common Stock in lieu of cash. Contour's issuance of the 100,000 shares of
Contour Common Stock was not related to the Sun Loan or the RCA Loan. Each of
these transactions was authorized and approved by the boards of directors of RCA
and Contour. The RCA Loan was converted into 1,950,000 shares of Contour Common
Stock because RCA believed that the conversion ratio was favorable to RCA and
that RCA would derive considerable long-term value from its ownership of the
Contour Common Stock. See "--Interests of Certain Persons in the RCA
Merger--Loan Extension" and "--Loan Agreements."
 
    A meeting of the board of directors of Sun was held on January 15, 1997. The
results of preliminary business, legal and accounting due diligence
investigations of each of RCA and Contour were presented by Sun management and
by financial, legal and accounting advisors to Sun. At the conclusion of the
meeting, the board members determined that Sun's management and advisors should
continue their due diligence work with respect to the potential transactions
with RCA and Contour.
 
    On February 9, 1997, senior management of Sun, including Messrs. Turner,
Woltil and McInteer, and RCA, including Messrs. Brogdon and Rees, accompanied by
their respective financial and legal advisors, met in Dallas, Texas, to discuss
and negotiate the terms and conditions of each of the proposed RCA Merger and
the proposed Contour Merger.
 
    A meeting of the board of directors of Sun was held on February 10, 1997. At
that meeting, members of the board were updated regarding the status of
negotiations with RCA and Contour. In addition, follow-up reports were provided
by Sun management and by financial, legal and accounting advisors to Sun
regarding their continuing due diligence investigations of RCA and Contour. Sun
management also presented reports regarding their plans to integrate RCA and
Contour with Sun's existing businesses. J.P. Morgan presented financial analyses
of each of the proposed RCA Merger (the terms of which then contemplated a RCA
common exchange ratio of 0.6625 of Sun Common Stock for each share of RCA Common
Stock (the "Original RCA Common Exchange Ratio")) and the proposed Contour
Merger. See "--Opinion of Sun's Financial Advisor" and "The Contour
Merger--Opinion of Sun's Financial Advisor." At the conclusion of the meeting,
the board members determined that Sun's management and advisors
 
                                       76
<PAGE>
should continue negotiations with respect to each of the RCA Merger and the
Contour Merger and continue their due diligence investigations of each of RCA
and Contour.
 
    During the week of February 10, 1997, the parties and their advisors
continued to negotiate the terms of the proposed RCA Merger and Contour Merger.
 
    A meeting of the board of directors of Sun was held on February 13, 1997. At
that meeting, Sun management updated the board of directors of Sun regarding the
status of negotiations with RCA and Contour and the ongoing due diligence
investigations of RCA and Contour. J.P Morgan updated the board of directors of
Sun regarding its financial analyses of each of the proposed RCA Merger and the
proposed Contour Merger (indicating that no material change had occurred in such
analysis subsequent to its February 10 presentation to the board) and indicated
that, if requested, it expected to be in a position to deliver its opinions as
to the fairness to Sun, from a financial point of view, of the consideration to
be paid by Sun in each of the RCA Merger and the Contour Merger. After extensive
discussion, the board of directors of Sun approved the RCA Merger and the
Contour Merger, subject to, among other things, receipt of the above-referenced
opinions of J.P. Morgan. On February 17, 1996 J.P. Morgan delivered its written
opinions to the board of directors of Sun that, as of such date, the
consideration to be paid by Sun in each of the RCA Merger and the Contour Merger
was fair, from a financial point of view, to Sun. See "--Opinion of Sun's
Financial Advisor," and "The Contour Merger--Opinion of Sun's Financial
Advisor."
 
    On February 17, 1997, the RCA board of directors held a special meeting at
its headquarters in Atlanta, Georgia, to consider the proposed RCA Merger
Agreement and the transactions contemplated thereby, including the proposed
consideration to be paid to RCA shareholders. The RCA board heard reports from
RCA's senior management and representatives of its financial and legal advisors
on the key elements of the proposed transaction, including the background of,
and costs associated with, the transaction; operational, financial, legal and
regulatory due diligence conducted by RCA management and its advisors; the
proposed consideration to be paid to RCA shareholders; financial and valuation
analyses of the transaction; the ramifications of a "pooling of interests"
transaction; the tax consequences of the transaction; details of proposed
break-up fees; the terms of the proposed RCA Merger Agreement and proposed RCA
Stock Option Agreement; RCA's strategic alternatives; and the other matters
described below under "--RCA's Reasons for the RCA Merger; Recommendation of
RCA's Board of Directors."
 
    After extensive discussion, the RCA board of directors authorized RCA's
officers to execute the proposed RCA Merger Agreement and to take all necessary
actions to consummate the proposed RCA Merger, subject to the receipt of a
written opinion from NatWest that the Original RCA Common Exchange Ratio of
0.6625 shares of Sun Common Stock for each share of RCA Common Stock was fair,
from a financial point of view, to the holders of RCA Common Stock.
 
    On February 17, 1997, the Contour board of directors held a special meeting
in Atlanta, Georgia, to consider the proposed Contour Merger Agreement and the
transactions contemplated thereby, including the proposed consideration to be
paid to Contour stockholders. The Contour board heard reports from Contour's
senior management and representatives of its legal advisors on the key elements
of the proposed transaction, including the background of, and costs associated
with, the transaction; operational, financial, legal and regulatory due
diligence conducted by Contour management and its advisors; the proposed
consideration to be paid to Contour stockholders; financial and valuation
analysis of the transaction; the tax consequences of the transaction; details of
proposed break-up fees; the terms of the proposed Contour Merger Agreement and
proposed Contour Stock Option Agreement; Contour's strategic alternatives; and
the other matters described below under "The Contour Merger--Contour's Reasons
for the Contour Merger; Recommendation of Contour's Board of Directors."
 
    After extensive discussion, the Contour board of directors authorized
Contour's officers to execute the proposed Contour Merger Agreement and take all
necessary actions to consummate the proposed Contour Merger and retained SALI to
deliver a fairness opinion in connection with the proposed Contour Merger.
 
                                       77
<PAGE>
    On February 17, 1997, Sun, RCA Merger Sub and RCA executed the RCA Merger
Agreement, Sun, Contour Merger Sub and Contour executed the Contour Merger
Agreement, the principal shareholders of RCA executed the RCA Stock Option
Agreement and RCA executed the Contour Stock Option Agreement. On February 18,
1997, prior to the opening of trading on the NYSE, Sun, RCA and Contour issued a
joint press release announcing the RCA Merger and the Contour Merger. On
February 18, 1997, NatWest delivered its written opinion dated as of February
17, 1997 that the Original RCA Common Exchange Ratio of 0.6625 shares of Sun
Common Stock for each share of RCA Common Stock, was fair, from a financial
point of view, to the holders of RCA Common Stock. On April 8, 1997, SALI
delivered its written opinion that the consideration to be paid by Sun in the
Contour Merger was fair, from a financial point of view, to the holders of
Contour Common Stock. See "The Contour Merger--Opinion of Contour's Financial
Advisor."
 
    In April 1997, Sun's accounting advisors informed Sun and RCA that a
provision in the RCA Merger Agreement which granted to certain principal
shareholders of RCA an option to purchase the shares of In-House Rehab
Corporation (formerly known as Perennial Development Corporation)("In-House")
owned by RCA at a negotiated price not to exceed the book value thereof raised
certain issues regarding the accounting treatment for the RCA Merger. See
"--Accounting Treatment." During April and May, the parties and their
accounting, financial and legal advisors discussed various proposals to amend
the RCA Merger Agreement. On May 9, 1997, Sun and RCA reached an agreement in
principle to amend the RCA Merger Agreement to permit Sun to retain the
ownership of the shares of In-House owned by RCA and increase the Original RCA
Common Exchange Ratio of 0.6625 shares of Sun Common Stock for each share of RCA
Common Stock to an amended exchange ratio of 0.68265 shares of Sun Common Stock
for each share of RCA Common Stock (the "First Amended RCA Common Exchange
Ratio"). During the weeks of May 12 and May 19 the parties and their advisors
negotiated the terms of the proposed amendment to the RCA Merger Agreement.
 
    A meeting of the board of directors of Sun was held on May 12, 1997. At that
meeting, Sun management updated the board of directors of Sun regarding the
status of the RCA Merger and the agreement in principle that had been
tentatively reached on May 9. J.P. Morgan updated the board of directors of Sun
regarding its financial analysis of the proposed amendment to the terms of the
proposed RCA Merger (indicating that no material change had occurred in such
analysis subsequent to its February 10 presentation to the board) and indicated
that it expected to be in a position to deliver its opinion that the
consideration to be paid by Sun in the RCA Merger, after giving effect to the
increase in the Original RCA Common Exchange Ratio to the First Amended RCA
Common Exchange Ratio, was fair, from a financial point of view, to Sun. After
extensive discussion, the board of directors of Sun approved the amendment to
the RCA Merger Agreement that had been agreed to in principle on May 9 and
directed Sun's management and advisors to proceed with the RCA Merger as it was
proposed to be amended.
 
    A meeting of the board of directors of RCA was held on May 22, 1997. At that
meeting, RCA management updated the board of directors of RCA regarding the
status of the RCA Merger and the agreement in principle that had been
tentatively reached on May 9. NatWest delivered its written opinion, dated as of
May 22, 1997, that the First Amended RCA Common Exchange Ratio of 0.68265 shares
of Sun Common Stock for each share of RCA Common Stock was fair, from a
financial point of view, to the holders of RCA Common Stock. After extensive
discussion, the board of directors of RCA approved the amendment to the RCA
Merger Agreement that had been agreed to in principle on May 9 and directed
RCA's management and advisors to proceed with the RCA Merger as it was proposed
to be amended.
 
    On May 27, 1997, Sun, RCA Merger Sub and RCA executed Amendment No. 1 to the
RCA Merger Agreement. The amendment (i) eliminated a provision in the RCA Merger
Agreement that granted to Christopher F. Brogdon, Connie Brogdon, Edward E.
Lane, Darrell C. Tucker and Winter Haven Homes, Inc. an option to purchase the
shares of In-House owned by RCA at a negotiated price not to exceed the book
value thereof; (ii) prohibited Sun from selling the shares of In-House owned by
RCA,
 
                                       78
<PAGE>
subject to certain exceptions, or acquiring additional shares of capital stock
of In-House, for a period of 24 months following the RCA Effective Time and
required Sun to vote such shares for the election of director candidates with
In-House's management; (iii) increased the Original RCA Common Exchange Ratio of
0.6625 shares of Sun Common Stock for each share of RCA Common Stock to the
First Amended RCA Common Exchange Ratio of 0.68265 shares of Sun Common Stock
for each share of RCA Common Stock; and (iv) added to the RCA Merger Agreement
additional representations and warranties and covenants related to the accounts
receivable and accounts payable of RCA. On May 27, 1997, J.P. Morgan delivered
its written opinion that the consideration to be paid by Sun in the RCA Merger,
after giving effect to Amendment No. 1 to the RCA Merger Agreement, was fair,
from a financial point of view, to Sun. On May 28, 1997, Sun and RCA issued a
joint press release announcing the amendment of the RCA Merger Agreement.
 
    On July 10, 1997, Sun and RCA amended the terms of the $9,750,000 loan that
Sun made to RCA on January 10, 1997 to: (i) increase the applicable interest
rate by 2.0%; (ii) extend the maturity date to 120 days after the termination of
the RCA Merger Agreement; and (iii) replace the collateral securing the loan
with a second lien on all of RCA's accounts receivable. On July 10, 1997, Sun
also agreed to loan RCA an additional $5,000,000, which loan is also secured by
a second lien on all of RCA's accounts receivable. The additional $5,000,000
loan was funded on July 15, 1997. See "--Interests of Certain Persons in the RCA
Merger--Loan Extension" and "--Loan Agreements."
 
    In addition, on July 15, 1997, Sun and RCA entered into an agreement (the
"Management Agreement") pursuant to which Sun agreed to provide management
services to all 16 long-term care facilities operated by RCA in Virginia and
North Carolina. See "--Management Agreement."
 
    On August 14, 1997, C&L resigned as the independent accountants of each of
RCA and Contour.
 
    On August 15, 1997, William C. Warrick, Sun's Vice President, Corporate
Controller, accompanied by representatives of Sun's financial, legal and
accounting advisors, met with senior management of RCA to discuss the
circumstances surrounding C&L's resignation.
 
    On August 19, 1997, Sun's legal advisors contacted RCA's legal advisors and
informed them that in light of the circumstances surrounding C&L's resignation,
the significant deterioration in RCA's business and financial condition since
February 17, 1997 and the anticipated restatement of RCA's financial results for
the fiscal year ended June 30, 1996 and the first three quarters of fiscal 1997,
Sun believed a reduction in the First Amended RCA Common Exchange Ratio was
appropriate. Between August 19, 1997 and August 21, 1997, the parties and their
advisors negotiated the terms of the proposed amendment to the RCA Merger
Agreement and a related amendment to the Contour Merger Agreement.
 
    A meeting of the board of directors of Sun was held on August 21, 1997. At
that meeting, Sun's management and legal advisors updated the board of directors
of Sun regarding the status of the RCA Merger and the revised terms thereof that
had been negotiated. J.P. Morgan presented a sensitivity analysis regarding the
projected effect on the implied 1998 earnings of Sun at amended RCA common
exchange ratios ranging from 0.510 to 0.525 and delivered its oral opinion that,
as of August 21, 1997, the consideration to be paid by Sun in the RCA Merger was
fair, from a financial point of view, to Sun. See "--Opinion of Sun's Financial
Advisor." J.P. Morgan also indicated that no event had occurred that would cause
it to withdraw its opinion dated February 17 regarding the Contour Merger. After
extensive discussion, the board of directors of Sun approved Amendment No. 2 to
the RCA Merger Agreement and Amendment No. 1 to the Contour Merger Agreement and
directed Sun's management and advisors to proceed with the RCA Merger and the
Contour Merger as they were proposed to be amended.
 
    A meeting of the board of directors of RCA was held on August 21, 1997. At
that meeting, RCA's management and legal advisors updated the board of directors
of RCA regarding the status of the RCA Merger and the revised terms thereof that
had been negotiated. After extensive discussion, the board of directors of RCA
approved Amendment No. 2 to the RCA Merger Agreement and directed RCA's
 
                                       79
<PAGE>
management and legal advisors to proceed with the RCA Merger as it was proposed
to be amended, subject to receipt of a fairness opinion with respect to the
consideration payable to RCA's shareholders pursuant to Amendment No. 2 to the
RCA Merger Agreement.
 
    A meeting of the board of directors of Contour was held on August 21, 1997.
At that meeting, Contour's management and legal advisors updated the board of
directors of Contour regarding the status of the Contour Merger and the revised
terms thereof that had been negotiated. After extensive discussion, the board of
directors of Contour approved the amendment to the Contour Merger Agreement and
directed Contour's management and legal advisors to proceed with the Contour
Merger as it was proposed to be amended.
 
    On August 21, 1997, Sun, RCA Merger Sub and RCA executed Amendment No. 2 to
the RCA Merger Agreement. The amendment (i) decreased the First Amended RCA
Common Exchange Ratio from 0.68265 shares of Sun Common Stock for each share of
RCA Common Stock to an amended exchange ratio of 0.520 shares of Sun Common
Stock for each share of RCA Common Stock (the "Second Amended RCA Common
Exchange Ratio"); (ii) contained certain provisions requiring RCA to revise and
restate its fiscal 1997 financial statements for the quarters ended September
30, 1996, December 31, 1996 and March 31, 1997; (iii) waived certain
representations and warranties which had become incorrect since the date of the
RCA Merger Agreement and quantified the materiality threshold applicable to the
defined term "Company Material Adverse Effect"; (iv) contained certain
provisions relating to the resignation of C&L as RCA's independent auditors; (v)
amended the provisions of the RCA Merger Agreement related to indemnification of
RCA's officers and directors; and (vi) extended the date after which either
party may freely terminate the RCA Merger Agreement from September 30, 1997 to
November 30, 1997 (or, under certain circumstances, to December 31, 1997). On
August 22, 1997, Sun and RCA issued a joint press release announcing the
amendment of the RCA Merger Agreement.
 
    On August 21, 1997, Sun, Contour Merger Sub and Contour executed Amendment
No. 1 to the Contour Merger Agreement. The amendment extended the date after
which either party might then freely terminate the Contour Merger Agreement from
September 30, 1997 to November 30, 1997 (or, under certain circumstances, to
December 31, 1997).
 
    On August 21, 1997, each of RCA and Contour filed a Current Report on Form
8-K (the "RCA 8-K" and the "Contour 8-K," respectively) relating to C&L's
resignation as each such company's independent accountants. The RCA 8-K also
announced that the audit committee of RCA's board of directors had been
instructed to conduct an investigation, with the assistance of outside counsel,
into the circumstances underlying the recording of certain inventory adjustments
aggregating approximately $1.7 million, which adjustments had a materially
favorable impact on RCA's operating results as reported in its fiscal year 1997
interim financial statements, and other potential adjustments to RCA's quarterly
financial statements previously reported in RCA's Quarterly Reports on Forms
10-Q for the first, second and third quarters of fiscal year 1997.
 
    Between August 25, 1997 and October 24, 1997, ten putative class action
lawsuits were filed in the United States District Court for the Northern
District of Georgia on behalf of persons who purchased RCA Common Stock, naming
RCA and certain of its officers and directors as defendants. The complaints have

securities laws by the defendants for disseminating allegedly false and
misleading financial statements for RCA's fiscal year ended June 30, 1996 and
its first three quarters of fiscal year 1997, which the plaintiffs allege
materially overstated RCA's profitability. Generally, each of the Actions seeks
unspecified compensatory damages, pre-judgment and post-judgment interest,
attorneys' fees and costs and other equitable and injunctive relief. See "Risk
Factors--Risk Factors Concerning RCA and Contour--Shareholder Litigation."
 
    On September 5, 1997, C&L delivered letters to the Securities and Exchange
Commission, as required by Item 304(a)(3) of Regulation S-K, in which C&L stated
that (i) C&L did not disagree with the statements made by Contour concerning C&L
in the Contour 8-K, (ii) C&L agreed with the matters reported in the RCA 8-K,
(iii) certain additional disagreements would have been referred to had such
disagreements not been resolved to C&L's satisfaction and (iv) C&L concluded
that it was unable to rely on RCA management's representations and did not
intend to be associated with any of RCA's filings that may be made pursuant to
the Securities Act or the Exchange Act and that, accordingly, C&L's report on
C&L's audit of RCA's fiscal 1996 financial statements should no longer be relied
upon.
 
    On September 5, 1997, RCA and Contour filed amendments to the RCA 8-K and
the Contour 8-K, respectively, in which the respective September 5 C&L letters
were included and each company announced that CB&H has been engaged to reaudit
such company's fiscal 1996 financial statements and to audit such company's
fiscal 1997 financial statements.
 
    A meeting of the board of directors of RCA was held on September 9, 1997. At
that meeting, RCA's management and legal advisors informed the board of
directors of RCA that RCA was not in a position to engage a financial advisor to
render a fairness opinion regarding the revised terms of the RCA Merger until
CB&H had completed its audit of RCA's 1996 and 1997 financial statements. The
RCA board of directors did not believe that obtaining a fairness opinion in
connection with the RCA Merger was necessary because the RCA board of directors
believed that it could evaluate the risks and merits of the RCA Merger and make
a recommendation to RCA's shareholders with respect to the RCA Merger without
such opinion. The RCA board considered management's analysis of the fairness of
the consideration to be received by RCA's shareholders pursuant to the RCA
Merger. Management compared the terms of the RCA Merger as amended by Amendment
No. 2 to the terms of comparable transactions within the industry and found that
the terms of the RCA Merger as amended by Amendment No. 2 exceeded the industry
average for the following transaction multiples: (i) adjusted transaction value
to last twelve months of Earnings Before Interest, Taxes, Depreciation,
Amortization and Rent ("EBITDAR"); (ii) transaction value to last twelve months'
revenues; (iii) transaction value to last twelve months' EBITDAR; (iv) market
value of equity to last twelve months of net income; and (v) market value of
equity to book value. After extensive discussions, the board of directors of RCA
determined to proceed with the
 
                                       81
<PAGE>
RCA Merger without obtaining a fairness opinion. See "Risk Factors--Risk Factors
Concerning the Mergers--Lack of a Fairness Opinion in Connection with the RCA
Merger," and "--RCA's Reasons for the RCA Merger; Recommendation of RCA's Board
of Directors."
 
    On September 18, 1997 C&L notified Contour that it did not intend to be
associated with Contour's filings which may be made pursuant to the Securities
Act or the Exchange Act and that its report on its audit of the Contour's
financial statements for the fiscal year ended June 30, 1996 should no longer be
relied upon.
 
    On October 14, 1997, RCA and Contour each filed amended annual reports on
Form 10-K/A restating their results for the fiscal year ended June 30, 1996, and
on October 23, 1997, RCA and Contour each filed amended quarterly reports on
Form 10-Q/A restating their results for the first three quarters of fiscal 1997.
See "Risk Factors--Risk Factors Concerning RCA and Contour--Resignation of
Independent Accountants; Restatement of Financial Statements."
 
    On November 17, 1997, Sun's legal advisors contacted RCA's legal advisors
and informed them that in light of the continued deterioration in RCA's business
and financial condition since the date of Amendment No. 2, C&L's statement that
its audit report on RCA's financial statements for the fiscal year ended June
30, 1996 should not be relied upon because C&L concluded that it could no longer
rely on RCA management's representations and the expansion of the class period
in the Actions to include RCA's 1996 fiscal year, Sun believed a reduction in
the Second Amended RCA Common Exchange Ratio was appropriate. On November 20,
1997, Messrs. Turner and Woltil met Messrs. Brogdan and Rees, each side
accompanied by their legal advisors, in Dallas, Texas, to explore whether a
renegotiated transaction was possible. The general structure of a revised
transaction was agreed upon.
 
    Between November 21, 1997 and November 25, 1997, the parties and their
respective advisors negotiated the terms of the proposed amendment to the RCA
Merger Agreement and related amendments to the Contour Merger Agreement, the RCA
Stock Option Agreement and the Contour Stock Option Agreement.
 
    A meeting of the board of directors of Sun was held on November 24, 1997. At
that meeting, Mr. Turner informed the board of directors of Sun of developments
relating to RCA since the date of Amendment No. 2 to the RCA Merger Agreement,
including the continued deterioration in RCA's business and financial condition,
the status of Sun's due diligence investigation of RCA following C&L's
resignation and the status of the Actions. Sun's management and legal advisors
updated the board of directors of Sun regarding the status of the RCA Merger and
the revised terms thereof that had been negotiated and certain remaining open
issues related thereto. J.P. Morgan presented its financial analysis of the
revised terms of the RCA Merger and delivered its oral opinion (later confirmed
in writing) that, as of November 24, 1997, the consideration to be paid by Sun
in the RCA Merger was fair, from a financial point of view, to Sun. See
"--Opinion of Sun's Financial Advisor." J.P. Morgan also indicated that no event
had occurred that would cause it to withdraw its opinion dated February 17
regarding the Contour Merger. After extensive discussion, the board of directors
of Sun approved Amendment No. 3 to the RCA Merger Agreement, Amendment No. 2 to
the Contour Merger Agreement and Amendment No. 1 to each of the RCA and Contour
Stock Option Agreements, and directed Sun's management and advisors to proceed
with the RCA Merger and the Contour Merger as they were proposed to be amended,
subject to satisfactory resolution of the remaining open issues, including the
entry into a memorandum of understanding with the plaintiffs in the Actions
regarding an acceptable settlement of the Actions.

    A meeting of the board of directors of Contour was held on November 24,
1997. At that meeting, Contour's management and legal advisors updated the board
of directors of Contour regarding the status of the Contour Merger and the
revised terms thereof that had been negotiated. After extensive discussion, the
board of directors of Contour approved the amendment to the Contour Merger
Agreement and directed Contour's management and legal advisors to proceed with
the Contour Merger as it was proposed to be amended.
 
    On November 25, 1997, RCA, Sun and representatives of the plaintiffs entered
into the MOU pursuant to which Sun has agreed to pay $9 million into an
interest-bearing escrow account maintained by Sun (the "Escrow Account") to
settle the Actions (the "Settlement"). RCA also agreed to assign coverage under
its directors' and officers' liability insurance policy, referred to below, for
these specific claims to the plaintiffs. The Settlement is contingent upon the
closing of the RCA Merger and confirmatory discovery and is subject to the
execution of definitive documentation and court approval. Upon satisfaction of
the conditions precedent to the Settlement, all claims by the class that were or
could have been asserted by the plaintiffs against RCA or any of the other
defendants in the Actions will be settled and released and the Actions will be
dismissed in their entirety with prejudice in exchange for the release of all
funds from the Escrow Account to the plaintiffs. Court approval of the
Settlement will not be sought until after the closing of the RCA Merger. On
February 13, 1998, the plaintiffs filed a motion seeking to compel the immediate
production of confirmatory discovery. On March 9, 1998, RCA filed a brief
opposing plaintiffs' motion arguing, INTER ALIA, that it is not required under
the MOU to provide confirmatory discovery prior to the closing of the RCA
Merger. On April 28, 1998, the court denied the plaintiffs' motion for immediate
discovery but ruled instead that if the RCA Merger closes on or before June 30,
1998, confirmatory discovery must be produced within 30 days after the RCA
Effective Time.
 
    On November 25, 1997, Sun, RCA Merger Sub and RCA executed Amendment No. 3
to the RCA Merger Agreement. The amendment decreased the Second Amended RCA
Common Exchange Ratio from 0.520 shares of Sun Common Stock for each share of
RCA Common Stock to the RCA Common Exchange Ratio, equal to the number of shares
of Sun Common Stock having a market value, based on an average closing price for
the Sun Common Stock, equal to $10.00 per share (unless such average closing
price exceeds $24.20 per share, in which case the RCA Common Exchange Ratio will
be 0.413 shares of Sun Common Stock for each share of RCA Common Stock, or
unless such average closing price is less than $19.80 per share, in which case
the RCA Common Exchange Ratio will be 0.505 shares of Sun Common Stock for each
share of RCA Common Stock). Amendment No. 3 to the RCA Merger Agreement also (i)
waived certain representations and warranties which had become incorrect since
the date of the RCA Merger Agreement; (ii) modified the definition of "Company
Material Adverse Effect" to relate only to changes in the assets or liabilities
of RCA; (iii) contained provisions relating to Sun and its affiliates providing
ancillary services to RCA and its affiliates; (iv) contained provisions allowing
RCA to obtain up to $15 million in working capital financing under certain
conditions; (v) contained provisions relating to certain related company leases;
(vi) modified the conditions to Sun's obligations to consummate the RCA Merger
related to RCA's representations and warranties and made corresponding
modifications in Sun's termination rights; (vii) provided for a termination fee
payable to RCA in the event Sun's board of directors changes its recommendation
of the RCA Merger in a manner adverse to RCA; (viii) contained certain other
technical provisions; and (ix) extended the date after which either party may
freely terminate the RCA Merger Agreement from November 30, 1997 (or under
certain circumstances, December 31, 1997) to March 31, 1998. On November 25,
1997, Sun, Contour Merger Sub and Contour executed Amendment No. 2 to the
Contour Merger Agreement. The amendment extended the date after which either
party may freely terminate the Contour Merger Agreement from November 30, 1997
(or under certain circumstances, December 31, 1997) to March 31, 1998 and
contained certain other technical provisions. See "The RCA Merger--Amendments to
the RCA Merger Agreement" and "The Contour Merger Agreement--Amendments to the
Contour Merger Agreement."
 
    On November 25, 1997, Sun and the principal stockholders of RCA also entered
into an amendment to the RCA Stock Option Agreement so as to (i) modify the
exercise price of the option described therein
 
                                       83
<PAGE>
to $10.00 per share of RCA Common Stock, (ii) not allow Sun to exercise the
option thereunder in the event that Sun was in material breach of the RCA Merger
Agreement and (iii) shorten the period during which Sun may exercise such option
from 120 days to 14 days. See "The RCA Stock Option Agreement."
 
    On November 25, 1997, Sun and RCA also entered into an amendment to the
Contour Stock Option Agreement so as to (i) provide certain registration rights
to RCA in the event that Sun pays the exercise price of the option thereunder in
shares of Sun Common Stock, (ii) not allow Sun to exercise the option thereunder
in the event that Sun was in material breach of the Contour Merger Agreement,
and (iii) shorten the period during which Sun may exercise such option from 120
days to 14 days. See "The Contour Stock Option Agreement."
 
    On November 26, 1997, Sun and RCA issued a joint press release announcing
the amendment of the RCA Merger Agreement, the Contour Merger Agreement, the RCA
Stock Option Agreement and the Contour Stock Option Agreement and the settlement
of the Actions.
 
    On March 30, 1998, Sun's legal advisors contacted RCA's legal advisors to
discuss an amendment to the RCA Merger Agreement and the Contour Merger
Agreement to extend the date after which either party may freely terminate the
RCA Merger Agreement and the Contour Merger Agreement beyond March 31, 1998.
Between March 30, 1998 and April 1, 1998, the parties and their respective legal
advisors negotiated the terms of the proposed amendments to the RCA Merger
Agreement and the Contour Merger Agreement.
 
    A meeting of the board of directors of RCA was held on April 3, 1998. At
that meeting, RCA's management and legal advisors updated the board of directors
of RCA regarding the status of the RCA Merger and the revised terms thereof that
had been negotiated. After a thorough discussion, the board of directors of RCA
approved Amendment No. 4 to the RCA Merger Agreement and directed RCA's
management and legal advisors to proceed with the RCA Merger as it was proposed
to be amended.
 
    A meeting of the board of directors of Contour was held on April 2, 1998. At
that meeting, Contour's management updated the board of directors of Contour
regarding the status of the Contour Merger and the revised terms thereof that

Contour approved Amendment No. 3 to the Contour Merger Agreement and directed
Contour's management and legal advisors to proceed with the Contour Merger as it
was proposed to be amended.
 
    A meeting of the board of directors of Sun was held on April 3, 1998. At

the status of the RCA Merger and Contour Merger, the status of the Actions, the
proposed extension of the date after which either party may freely terminate the
RCA Merger Agreement and the Contour Merger Agreement beyond March 31, 1998, and
the additional condition to Sun's obligation to consummate the RCA Merger that
the MOU entered into in connection with the settlement of the Actions remain in
effect. After a thorough discussion, the board of directors of Sun approved
Amendment No. 4 to the RCA Merger Agreement and Amendment No. 3 to the Contour
Merger Agreement and directed Sun's management and legal advisors to proceed
with the RCA Merger and the Contour Merger as they were proposed to be amended.
 
    As of April 3, 1998, Sun, RCA Merger Sub and RCA executed Amendment No. 4 to
the RCA Merger Agreement. The amendment added as a condition to Sun's obligation
to consummate the RCA Merger a requirement that the MOU entered into in

SUN'S REASONS FOR THE RCA MERGER; RECOMMENDATION OF SUN'S BOARD OF DIRECTORS
 
    The board of directors of Sun has carefully considered the advisability of
the RCA Merger and believes that the terms of the RCA Merger Agreement are fair
to, and that the RCA Merger is in the best interests of, Sun's stockholders. THE
BOARD OF DIRECTORS OF SUN HAS UNANIMOUSLY APPROVED AND ADOPTED THE RCA MERGER
AGREEMENT AND APPROVED THE RCA MERGER, AND UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF SUN VOTE FOR THE APPROVAL AND ADOPTION OF THE RCA MERGER
AGREEMENT AND APPROVAL OF THE RCA MERGER AND THE ISSUANCE OF SUN COMMON STOCK
AND SUN PREFERRED STOCK PURSUANT THERETO.
 
    In the course of its deliberations, the board of directors of Sun reviewed,
and consulted with Sun's management and its financial and legal advisors
concerning, a number of factors relevant to the RCA Merger. In particular, the
board of directors of Sun identified several potential benefits of the RCA
Merger to Sun and its stockholders, among other things:
 
    (i) the ability to extend Sun's position as a diversified healthcare company
by acquiring RCA's portfolio of long-term care, assisted living and independent
living facilities;
 
    (ii) the ability to acquire a strong market position in geographic markets
in which Sun does not currently have a presence and the complementary geographic
locations of a number of Sun facilities and RCA facilities, which may provide an
opportunity to realize potential synergies;
 
   (iii) the ability to provide higher margin ancillary services, such as
rehabilitation and respiratory therapy services, temporary therapist staffing
and pharmacy services in RCA's facilities;
 
    (iv) the potential ability to address the medical needs of higher acuity
patients and thereby increase overall acuity levels at RCA's facilities and
improve the patient mix;
 
    (v) the written opinion of J.P. Morgan, dated as of November 24, 1997 that,
as of the date of such opinion, the consideration to be paid by Sun in the RCA
Merger was fair, from a financial point of view, to Sun (see "--Opinion of Sun's
Financial Advisor");
 
    (vi) RCA's business, operations and prospects;
 
   (vii) the opportunities for economies of scale that may result from the RCA
Merger, particularly in terms of the combined purchasing power of the two
companies;
 
  (viii) the terms and conditions of the RCA Merger Agreement, including that
the RCA Merger will be accounted for under the pooling of interests method of
accounting and will be a tax-free reorganization for federal income tax
purposes;
 
    (ix) the historical market prices of, and other information with respect to,
the Sun Common Stock and the RCA Common Stock;
 
    (x) the prospects for the long-term performance of Sun Common Stock as well
as the potential volatility of such stock;
 
    (xi) the ability of the RCA Merger to allow Sun to become a more efficient
and profitable provider of healthcare services, particularly as a result of
items (iii), (iv) and (vii) above, and thereby better position Sun to deal with
uncertainties which may face the healthcare industry due to healthcare reform;
 
   (xii) the reduction in the exchange ratio from the original RCA Common
Exchange Ratio of 0.6625 shares of Sun Common Stock for each share of RCA Common
Stock to the RCA Common Exchange Ratio, equal to the number of shares of Sun
Common Stock having a market value, based on an average closing price for the
Sun Common Stock, equal to $10.00 per share (unless such average closing price
exceeds $24.20 per share, in which case the RCA Common Exchange Ratio will be
0.413 shares of Sun Common Stock for each share of RCA Common Stock, or unless
such average closing price is less than $19.80 per share, in which case the RCA
Common Exchange Ratio will be 0.505 shares of Sun Common Stock for each share of
RCA Common Stock), which would result in fewer shares of Sun Common Stock being
issued in the RCA Merger than under the original RCA Merger Agreement; and
 
                                       85
<PAGE>
  (xiii) the entry into the MOU with the plaintiffs in the Actions, which was a
condition to the board of directors of Sun's decision to proceed with the RCA
Merger and approve Amendment No. 3 to the RCA Merger Agreement.
 
    The board of directors of Sun also considered a variety of inherent risks
and other potentially negative factors in its deliberations concerning the RCA
Merger. In particular, the board of directors of Sun considered, among other
things:
 
    (i) the potential dilutive effect of the issuance of Sun Common Stock and
Sun Preferred Stock pursuant to the RCA Merger;
 
    (ii) the substantial charge of $30,000,000 expected to be incurred,
primarily in the quarter ending June 30, 1998, in connection with the RCA
Merger, including costs of integrating the businesses and transaction expenses
arising from the RCA Merger (see "Risk Factors--Risk Factors Concerning the
Mergers--Difficulty of Integrating Acquired Operations");
 
   (iii) the risk that public market price of the Sun Common Stock might be
adversely affected by announcement of the RCA Merger;
 
    (iv) the risks associated with integrating the operations of RCA with Sun's
existing operations, including the loss of key personnel and institutional
memory of RCA, difficulty in integrating corporate, accounting, financial
reporting and management information systems and strain on existing levels of
personnel to operate RCA's business (see "Risk Factors--Risk Factors Concerning
the Mergers--Difficulty of Integrating Acquired Operations" and "--Management of
Growth");
 
    (v) the risks associated with the assumption of RCA's existing indebtedness
(which totaled $172.7 million as of September 30, 1997) in light of Sun's
substantial consolidated indebtedness (which would have totalled $903 million as
of September 30, 1997 on a pro forma basis after giving effect to the Regency
Acquisition and the consummation of the Credit Facility) (see "Risk
Factors--Risk Factors Concerning Sun--Substantial Leverage; Ability to Service
Debt");
 
    (vi) the risks associated with the expansion of Sun's therapy, temporary
staffing and pharmaceutical services contemplated in connection with the
acquisition of RCA (see "Risk Factors--Risk Factors Concerning Sun--Risks
Associated with the Development and Expansion of Ancillary Services");
 
   (vii) the resignation of C&L as RCA's independent auditors, including C&L's
statement that its audit report on RCA's financial statements for the fiscal
year ended June 30, 1996 should not be relied upon because C&L concluded that it
could no longer rely on RCA management's representations (see "Risk
Factors--Risk Factors Concerning RCA and Contour--Resignation of Independent
Accountants; Restatement of Financial Statements");
 
  (viii) the restatement of RCA's financial results for the fiscal year ended
June 30, 1996 and for the first three quarters of fiscal 1997 and the increased
risk that the assumptions made by Sun regarding the financial conditions of RCA
may later prove to be incorrect (see "Risk Factors--Risk Factors Concerning RCA
and Contour--Resignation of Independent Accountants; Restatement of Financial
Statements");
 
    (ix) the potential for additional litigation that may be brought against
RCA, including obligations that Sun might have towards the directors and
officers of RCA as a result of Sun's agreement to indemnify such individuals in
certain circumstances (see "Risk Factors--Risk Factors Concerning the
Mergers--Lack of a Fairness Opinion in Connection with the RCA Merger," "--Risk
Factors Concerning RCA and Contour-- Shareholder Litigation," "--Risk Factors
Concerning RCA and Contour--Other Litigation" and "The RCA Merger--Interests of
Certain Persons in the RCA Merger--Indemnification; Indemnification
Agreements");
 
    (x) the significant deterioration in RCA's business and financial condition
since February 17, 1997 (see "Risk Factors--Risk Factors Concerning RCA and
Contour--Deterioration of RCA's Recent Financial Condition; Noncompliance with
Certain Covenants; Delinquent Property Taxes"); and
 
                                       86
<PAGE>
    (xi) other risks described above under "Risk Factors."
 
    In addition, the Board of Directors of Sun considered certain risks
associated with not consummating the RCA Merger, including the loss of potential
future revenues from the provision of certain services to RCA, the potential
impairment of Sun's ability to collect certain amounts owed to it by RCA (which
totaled approximately $27.9 million as of December 31, 1997) and the failure to
obtain the potential benefits of the RCA Merger. See "Risk Factors--Risk Factors
Concerning the Mergers--Adverse Effects of Failure to Consummate the
Mergers--Sun."
 
    Although the board of directors of Sun did not receive quantitative analysis
of all of the factors listed above, based on the foregoing matters, and such
other matters as the members of the board of directors of Sun deemed relevant,
including the board's familiarity with the long-term care industry, the
recommendation of management of Sun and the conclusion of the board of directors
of Sun that the aggregate benefit of the positive factors described above
outweighed the aggregate detriment of the negative factors described above,
Sun's board of directors unanimously approved the RCA Merger Agreement and the
transactions contemplated thereby.
 
    The foregoing discussion of the information and factors considered and given
weight by the board of directors of Sun is not intended to be exhaustive but
includes all material factors considered by the board of directors of Sun. In
addition, in reaching the determination to approve and recommend the RCA Merger
Agreement and the transactions contemplated thereby, the board of directors of
Sun did not assign any relative or specific weights to the foregoing factors
which were considered, and individual directors may have given differing weights
to different factors. The board of directors of Sun is, however, unanimous in
its recommendation to the holders of Sun Common Stock that the RCA Merger
Agreement and the transactions contemplated thereby be approved.
 
RCA'S REASONS FOR THE RCA MERGER; RECOMMENDATION OF RCA'S BOARD OF DIRECTORS
 
    The board of directors of RCA has carefully considered the advisability of
the RCA Merger, and believes that the terms of the RCA Merger Agreement are fair
to, and that the RCA Merger is in the best interests of, RCA and its
shareholders. THE BOARD OF DIRECTORS OF RCA HAS UNANIMOUSLY APPROVED AND ADOPTED
THE RCA MERGER AGREEMENT AND APPROVED THE RCA MERGER, AND UNANIMOUSLY RECOMMENDS
THAT THE SHAREHOLDERS OF RCA VOTE FOR THE APPROVAL AND ADOPTION OF THE RCA
MERGER AGREEMENT AND APPROVAL OF THE RCA MERGER.
 
    In the course of its deliberations with respect to Amendment No. 3 to the
RCA Merger Agreement ("Amendment No. 3"), the board of directors of RCA
reviewed, and consulted with RCA's management and its legal advisors concerning,
a number of factors relevant to the RCA Merger. The material factors considered
by the RCA board in reaching its conclusion to approve Amendment No. 3 and
recommend the approval and adoption of the RCA Merger Agreement, as amended, by
RCA's shareholders are set forth below. THE RCA BOARD DID NOT ENGAGE A FINANCIAL
ADVISOR OR OBTAIN A FAIRNESS OPINION IN CONNECTION WITH ITS DECISION TO APPROVE
AMENDMENT NO. 3 AND RECOMMEND THE APPROVAL AND ADOPTION OF THE RCA MERGER
AGREEMENT, AS AMENDED. Shareholders of RCA, in evaluating whether to approve and
adopt the RCA Merger Agreement and approve the RCA Merger, should consider the
fact that the board of directors of RCA did not engage a financial advisor or
obtain a fairness opinion in connection with its decision to make such
recommendation. See "Risk Factors--Risk Factors Concerning the Mergers--Lack of
a Fairness Opinion in Connection with the RCA Merger."
 
        1.  The RCA board reviewed the risks faced by RCA and the attendant
    risks to RCA's shareholders if the RCA Merger Agreement were terminated. The
    RCA board believed that, if the RCA Merger Agreement were terminated, there
    would be a substantial decrease in the price of the RCA Common Stock due to
    (i) the elimination of the merger premium currently reflected in RCA's stock
    price and (ii) the adverse reaction of the marketplace to the pendency of
    numerous shareholder lawsuits against RCA and certain of its officers and
    directors and to RCA's operating loss of approximately $9.4 million for the
    fiscal year ended June 30, 1997. The RCA board also observed that RCA would
    face difficulties in executing its business plan of being a leading provider
    of senior
 
                                       87
<PAGE>
    residential care facilities in the southeastern United States if the
    marketplace believed that RCA might not remain an independent company and
    the identity of its future owner was unknown.
 
        2.  The RCA board noted that there had been no credible offer from any
    third party expressing an interest in acquiring RCA since the initial
    announcement of the RCA Merger and that, in light of (i) RCA's restatement
    of its earnings and the resignation of its auditors, (ii) the class action
    lawsuits referred to under "Risk Factors--Risk Factors Concerning RCA and
    Contour--Shareholder Litigation" and (iii) RCA's operating loss of
    approximately $9.4 million for the fiscal year ended June 30, 1997, it was
    unlikely that RCA would receive a higher offer from another merger partner.
 
        3.  The RCA board determined that the consideration to be paid to the
    RCA shareholders in the RCA Merger represents a premium of approximately 42%
    over the average trading price of the RCA Common Stock for the three-month
    period immediately preceding December 9, 1996, the date on which speculation
    first began in the press concerning the possibility that RCA might be
    acquired; represents a valuation for the RCA Common Stock that could not be
    achieved as quickly, if at all, if RCA were to remain an independent entity;
    and represents a premium of approximately 21% over the closing price of the
    RCA Common Stock on the date of the execution of Amendment No. 3.
 
        4.  Based on the closing price of the Sun Common Stock of $21.00 per
    share on November 25, 1997, the market value of the consideration that would
    have been paid to the RCA shareholders would have been $13.91 per share
    under the Original RCA Common Exchange Ratio as compared with $10.00 per
    share under the RCA Common Exchange Ratio. However, the RCA board noted
    that, despite the adverse developments that have occurred since the date of
    Amendment No. 2 and the decrease in the applicable exchange ratio, the
    market value of the consideration to be paid to RCA's shareholders pursuant
    to Amendment No. 3, based on the closing price of the Sun Common Stock as of
    the date of Amendment No. 3 (which had risen significantly since the date of
    RCA Merger Agreement); and the RCA Common Exchange Ratio, was in excess of
    the market value of the consideration that would have been paid to RCA's
    shareholders under the original terms of the RCA Merger Agreement (which
    provided for an Original RCA Common Exchange Ratio of 0.6625 shares of Sun
    Common Stock for each share of RCA Common Stock) based on the closing price
    of the Sun Common Stock as of the date thereof.
 
        5.  The RCA board noted that, in entering into Amendment No. 3, Sun had
    agreed to (i) allow RCA's schedule of exceptions to its representations and
    warranties to be updated for exceptions subsequent to August 21, 1997 (the
    date of Amendment No. 2 to the RCA Merger Agreement); (ii) modify the
    definition of "Company Material Adverse Effect" to relate only to changes in
    the assets or liabilities of RCA; (iii) modify the conditions to Sun's
    obligation to consummate the RCA Merger related to RCA's representations and
    warranties and make corresponding modifications in Sun's termination rights;
    and (iv) pay a termination fee to RCA in the event Sun's board of directors
    changes its recommendation of the RCA Merger in a manner adverse to RCA,
    thus providing greater certainty that the RCA Merger would be consummated
    and reducing the risk of another renegotiation of the terms thereof prior to
    March 31, 1998 (the date after which either party might have freely
    terminated the RCA Merger Agreement). The RCA board also noted that
    Amendment No. 3 retained the provisions of the RCA Merger Agreement allowing
    RCA to respond to unsolicited offers under certain circumstances.
 
    In addition to the factors described above, in reaching its conclusion to
approve Amendment No. 3 and recommend the approval and adoption of the RCA
Merger Agreement, as amended, by RCA's shareholders, the RCA board also
considered the following factors that it had also considered in approving the
original RCA Merger Agreement and Amendments No. 1 and 2 thereto:
 
    (i) the RCA Merger should permit Sun to provide a full range of
higher-margin ancillary services, including pharmacy operations, therapy and
subacute care, which services are not now provided by RCA, to RCA's healthcare
facilities, which should have a positive impact on Sun's operating performance;
 
                                       88
<PAGE>
    (ii) the complementary nature of the businesses of Sun and RCA have little
overlap and should create significant opportunities for the development of Sun
without the need for significant restructuring, redirection or asset
dispositions;
 
   (iii) Sun has a greater diversification of revenue sources, and possesses
greater managerial, operational and financial resources, than does RCA;
 
    (iv) Sun is expected to achieve certain administrative efficiencies and to
eliminate certain duplicate functions;
 
    (v) Sun should be able to achieve longer-term revenue enhancements and
facility expense efficiencies as a result of the combination of management
resources and operating assets and the integration and streamlining of certain
management, administrative and purchasing functions;
 
    (vi) the greater financial resources of Sun should permit an acceleration of
the development and expansion of new business and services;
 
   (vii) the market capitalization and public stock distribution of Sun will
provide RCA's shareholders with increased liquidity and that, as a result of the
RCA Merger, RCA's shareholders will continue as shareholders of a larger, more
diversified combined organization having greater market and financial strength;
 
  (viii) the expectation that the RCA Merger will be treated as a "pooling of
interests" transaction for accounting and financial reporting purposes (thereby
avoiding the reduction in earnings of Sun that would result from the
amortization of goodwill under purchase accounting) and will be treated as a
tax-free reorganization for federal income tax purposes;
 
    (ix) the business, managerial expertise, business stategy, prospects and
competitive position of RCA and Sun;
 
    (x) the historical, current and projected financial condition and results of
operations of RCA (without giving effect to the RCA Merger) and of Sun (after
giving effect to the RCA Merger); and
 
    (xi) general economic and stock market conditions.
 
    The RCA board also considered a variety of inherent risks and potentially
negative factors in its deliberations concerning Amendment No. 3 that it had
also considered in approving the original RCA Merger Agreement and Amendments
No. 1 and 2 thereto. In the view of the RCA board, these considerations did not
outweigh, individually or collectively, the advantages of the RCA Merger. In
particular, the RCA board considered the following:
 
    (i) the irreversible nature of the decision and the consequent loss of
independence;
 
    (ii) the possible change in certain existing RCA corporate policies and
strategies following the RCA Merger;
 
   (iii) the potential for post-merger dilution of Sun's earnings per share;
 
    (iv) risks associated with the pending investigation of Sun by the OIG and
the Civil Division of the U.S. Department of Justice (see "Risk Factors--Risk
Factors Concerning Sun--Investigations; Uncertain Impact on Future Operating
Results"); and
 
    (v) the other risks described above under "Risk Factors."
 
    In addition, the RCA board of directors considered certain risks associated
with not consummating the RCA Merger, including the potential continued or
accelerated deterioration of RCA's financial condition and results of
operations, the potential termination of the MOU and possible protracted
litigation, the potential default by RCA of its obligations to Sun under the
Loan Agreements and possible cross-default and acceleration under some of RCA's
other indebtedness, and the failure to obtain the potential benefits of the RCA
Merger. See "Risk Factors--Risk Factors Concerning the Mergers-- Adverse Effects
of Failure to Consummate the Mergers--RCA."
 
                                       89
<PAGE>
    Due to the wide variety of factors considered in connection with the
evaluation of the RCA Merger, RCA's board of directors did not find it
practicable to, and did not quantify or otherwise attempt to assign relative
weights to, the specific factors considered in reaching its determination. In
addition, individual members of RCA's board of directors may have given
different weight to different factors.
 
    RCA BOARD RECOMMENDATION.  RCA's board of directors has approved the RCA
Merger Agreement and the transactions contemplated thereby and determined that
the RCA Merger is fair to, and in the best interests of, RCA and its
shareholders. AFTER CAREFUL CONSIDERATION, THE BOARD OF DIRECTORS OF RCA
UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF RCA VOTE IN FAVOR OF THE RCA
MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY. The board of
directors of RCA did not engage a financial advisor or obtain a fairness opinion
in connection with its decision to recommend that RCA's shareholders approve and
adopt the RCA Merger Agreement, as amended by Amendment No. 3, and approve the
RCA Merger. As a result, RCA's shareholders will vote on the RCA Merger
Agreement and the RCA Merger without an opinion from an unaffiliated financial
advisor that the RCA Merger is fair, from a financial point of view, to the
shareholders of RCA. The RCA board of directors considered each of the factors
described above in determining to proceed with the RCA Merger without a fairness
opinion. The RCA board of directors did not believe that obtaining a fairness
opinion in connection with the RCA Merger was necessary because the RCA board of
directors believed that it could evaluate the RCA Merger and make a
recommendation to RCA's shareholders with respect to the RCA Merger without such
opinion. However, shareholders of RCA, in evaluating whether to approve and
adopt the RCA Merger Agreement and approve the RCA Merger, should consider the
fact that the board of directors of RCA did not engage a financial advisor or
obtain a fairness opinion in connection with its decision to make such
recommendation. See "Risk Factors--Risk Factors Concerning the Mergers--Lack of
a Fairness Opinion in Connection with the RCA Merger."
 
OPINION OF SUN'S FINANCIAL ADVISOR
 
    Pursuant to an engagement letter dated February 6, 1997, as amended on April
3, 1998, Sun retained J.P. Morgan to deliver a fairness opinion in connection
with the proposed RCA Merger.
 
    J.P. Morgan rendered opinions to the board of directors of Sun that, as of
the date of each of the original RCA Merger Agreement and Amendments Nos. 1 and
2 thereto, the consideration to be paid by Sun in the proposed RCA Merger was
fair, from a financial point of view, to Sun.
 
    On November 24, 1997, J.P. Morgan rendered its oral opinion (which was later
confirmed in writing)(such written opinion being referred to as the "J.P. Morgan
Opinion") (the inclusion of which in the Joint Proxy
Statement/Prospectus/Information Statement has been consented to by J.P. Morgan)
to the board of directors of Sun that, as of such date, the consideration to be
paid by Sun in the proposed RCA Merger was fair, from a financial point of view,
to Sun. The J.P. Morgan Opinion and J.P. Morgan's earlier opinions each
concluded that the consideration was fair, although J.P. Morgan relied on
different information and utilized different methodologies, in each case as it
considered appropriate, in reaching its conclusions. No limitations were imposed
by Sun's board of directors upon J.P. Morgan with respect to the investigations
made or procedures followed by it in rendering its opinions.
 
    THE FULL TEXT OF THE J.P. MORGAN OPINION DATED AS OF NOVEMBER 24, 1997,
WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE
REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX B TO THIS JOINT PROXY
STATEMENT/PROSPECTUS/INFORMATION STATEMENT AND IS INCORPORATED HEREIN BY
REFERENCE. SUN'S STOCKHOLDERS ARE URGED TO READ THE J.P. MORGAN OPINION IN ITS
ENTIRETY. THE J.P. MORGAN OPINION IS ADDRESSED TO THE BOARD OF DIRECTORS OF SUN,
IS DIRECTED ONLY TO THE CONSIDERATION TO BE PAID IN THE RCA MERGER AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF SUN AS TO HOW SUCH STOCKHOLDER
SHOULD VOTE AT THE SUN SPECIAL MEETING. THE SUMMARY OF THE J.P. MORGAN OPINION
SET FORTH IN THIS JOINT PROXY STATEMENT/ PROSPECTUS/INFORMATION STATEMENT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE J.P. MORGAN
OPINION.
 
    In arriving at the J.P. Morgan Opinion, J.P. Morgan reviewed, among other
things, the RCA Merger Agreement, including Amendments No. 1, 2 and 3 thereto;
the audited financial statements of RCA for the
 
                                       90
<PAGE>
fiscal years ended June 30, 1995, 1996 and 1997, and the unaudited financial
statements of RCA for the quarterly period ended September 30, 1997; the audited
financial statements of Sun for the fiscal years ended December 31, 1995 and
1996 and the unaudited financial statements of Sun for the quarterly periods
ended March 31, June 30 and September 30, 1997; current and historical market
prices of the RCA Common Stock; certain publicly available information
concerning the business of RCA and of certain other companies engaged in
businesses comparable to those of RCA, and the reported market prices for
certain other companies' securities deemed comparable; publicly available terms
of certain transactions involving companies comparable to RCA and the
consideration paid for such companies; the terms of other business combinations
deemed relevant by J.P. Morgan; certain internal financial analyses and
forecasts prepared by Sun and RCA and their respective managements; and certain
agreements with respect to outstanding indebtedness or obligations of Sun and
RCA. J.P. Morgan also held discussions with certain members of the management of
Sun and RCA with respect to certain aspects of the RCA Merger, and the past and
current business operations of Sun and RCA, the financial condition and future
prospects and operations of Sun and RCA, and certain other matters believed
necessary or appropriate to J.P. Morgan's inquiry. In addition, J.P. Morgan
visited certain representative facilities of RCA, and reviewed such other
financial studies and analyses and considered such other information as it
deemed appropriate for the purposes of the J.P. Morgan Opinion.
 
    J.P. Morgan relied upon and assumed, without independent verification, the
accuracy and completeness of all information that was publicly available or that
was furnished to it by Sun and RCA or otherwise reviewed by J.P. Morgan, and
J.P. Morgan has not assumed any responsibility or liability therefor. J.P.
Morgan has not conducted any valuation or appraisal of any assets or
liabilities, nor have any valuations or appraisals been provided to J.P. Morgan.
In relying on financial analyses and forecasts provided to J.P. Morgan, J.P.
Morgan has assumed that they have been reasonably prepared based on assumptions
reflecting the best currently available estimates and judgments by management as
to the expected future results of operations and financial condition of Sun and
RCA to which such analyses or forecasts relate.
 
    The projections furnished to J.P. Morgan for Sun and RCA were prepared by
the respective managements of each company. Neither Sun nor RCA publicly
discloses internal management projections of the type provided to J.P. Morgan in
connection with J.P. Morgan's analysis of the RCA Merger, and such projections
were not prepared with a view toward public disclosure. These projections were
based on numerous variables and assumptions that are inherently uncertain and
may be beyond the control of management, including, without limitation, factors
related to general economic and competitive conditions and prevailing interest
rates. Accordingly, actual results could vary significantly from those set forth
in such projections.
 
    The J.P. Morgan Opinion is based on economic, market and other conditions as
in effect on, and the information made available to J.P. Morgan as of, the date
of the J.P. Morgan Opinion. Subsequent developments may affect the J.P. Morgan
Opinion, and J.P. Morgan does not have any obligation to update, revise, or
reaffirm such opinion. J.P. Morgan expressed no opinion as to the price at which
the Sun Common Stock will trade at any future time.
 
    In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinions. The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing its opinion dated November 24, 1997.
 
    PUBLIC TRADING MULTIPLES.  Using publicly available information, J.P. Morgan
compared selected financial data of RCA with similar data for selected publicly
traded companies engaged in businesses that J.P. Morgan judged to be analogous
to RCA. The companies selected by J.P. Morgan were Advocat Inc., Arbor Health
Care Company, Beverly Enterprises Inc., Centennial Healthcare, Genesis Health
Ventures, Inc., Harborside Healthcare Corp., Health Care & Retirement
Corporation, Integrated Health Services, Inc., Living Centers of America, Inc.,
Manor Care Inc., Mariner Health Group, Inc., The Multicare Companies, Inc.,
Regency Health Services, Inc., Summit Care Corporation and Vencor Inc. These
companies were selected, among other reasons, because they provide long-term
care to patients and operate skilled nursing facilities. For each comparable
company, J.P. Morgan calculated an adjusted Firm
 
                                       91
<PAGE>
Value to Bed multiple. Firm Value (fully diluted equity multiplied by share
price plus net debt) was adjusted in two ways. First, eight times lease expense
was included in debt, as is commonplace in the long-term care industry. Second,
in order to normalize between companies that have various porportions of
ancillary and non-bed related revenue, Firm Value was reduced by a percentage
representing the amount of non-skilled-living facility ("SNF") bed and
non-assisted living facility ("ALF") bed-related revenue generated by each
company. In the denominator, Beds included the most recent publicly available
number of SNF and ALF beds owned by each comparable company (managed beds were
excluded). The multiples for Firm Value to Bed ranged from 26.2x to 116.1x with
a median of 56.3x. The median multiple was then applied to RCA's bed number of
approximately 10,200 beds. The range of implied values for RCA Common Stock was
$19.00 to $21.00 per share on a stand-alone basis.
 
    SELECTED TRANSACTION ANALYSIS.  Using publicly available information, J.P.
Morgan examined selected transactions with respect to the long-term care
industry. Specifically, J.P. Morgan reviewed the following transactions:
Vencor's acquisition of Hillhaven (1/26/95), Sun's acquisition of Mediplex
(1/27/94), GranCare's acquisition of Evergreen Healthcare (5/3/95), Genesis
Health Ventures' acquisition of Geriatric & Medical (7/11/96), Regency Health
Services acquisition of Care Enterprises (12/21/93), Mariner Health's
acquisition of Pinnacle Care (1/6/94), Genesis Eldercare's acquisition of
Multicare (6/16/97), GranCare's acquisition of Living Centers of America
(5/8/97), and Living Centers of America's acquisition of Vari-Care (6/14/93).
For each transaction, J.P. Morgan calculated an adjusted Firm Value to Bed
multiple. Firm Value (Equity Value plus net debt) was adjusted in two ways.
First, eight times lease expense was included in debt, as is commonplace in the
long-term care industry. Second, in order to normalize between companies that
have various proportions of ancillary and non-bed related revenue, Firm Value
was reduced by a percentage representing the amount of non-SNF bed and non-ALF
bed-related revenue generated by each company. In the denominator, Beds included
the most recent publicly available number of SNF and ALF beds owned by the
target company (excluding managed beds). The multiples ranged from 29.2x to
97.4x with a median multiple of 48.7x (compared to RCA's own multiple of 42.1x).
The median multiple was then applied to RCA's bed number of approximately 10,200
beds. The range of implied value for RCA Common Stock was $15.00 to $18.00 per
share.
 
    DISCOUNTED CASH FLOW ANALYSIS
 
        STAND-ALONE VALUE:  J.P. Morgan conducted a discounted cash flow
analysis for the purpose of determining the fully diluted equity value per share
for the RCA Common Stock on a stand-alone basis (i.e., without synergies). J.P.
Morgan calculated the unlevered free cash flows that RCA is expected to generate
on a stand-alone basis during fiscal years 1998 through 2001 based upon
financial projections prepared by the management of RCA through the years ended
December 31 and adjusted by J.P. Morgan, in accordance with instructions from
Sun's management, to reflect more moderate growth in revenues and lower
operating margins during the forecast period. For the purposes of this analysis,
J.P. Morgan assumed that the adjusted revenue growth rate stabilizes at 5
percent and the adjusted Earnings Before Interest, Taxes, Depreciation,
Amortization and Rent ("EBITDAR") margin improves from 12 percent to 15 percent
over the period analyzed. J.P. Morgan also calculated a range of stand-alone
terminal values of RCA as of December 31, 2001 by applying a perpetual growth
rate ranging from 3.0% to 4.0% to the unlevered free cash flow of RCA on a
stand-alone basis during the final year of the five-year period. The unlevered
free cash flows on a stand-alone basis and the range of stand-alone terminal
values were then discounted to present values using a range of discount rates
from 10.0% to 11.0%, which were chosen by J.P. Morgan based upon an analysis of
the weighted average cost of capital of RCA. The present value of the unlevered
free cash flows on a stand-alone basis and the range of stand-alone terminal
values were then adjusted for RCA's estimated September 30, 1997 excess cash,
option exercise proceeds and total adjusted debt (adjusted to include eight
times estimated 1998 rent expense as is common in the long-term care industry).
 
        SYNERGIES VALUE:  J.P. Morgan also conducted a discounted cash flow
analysis for the purpose of determining the fully diluted equity value per share
for RCA's potential revenue and cost synergies with
 
                                       92
<PAGE>
Sun. J.P. Morgan calculated the unlevered free cash flows from synergies that
RCA is expected to generate during fiscal years 1998 through 2001 based upon
financial projections prepared by the management of Sun and RCA through the
years ended December 31 and upon management projections adjusted by J.P. Morgan,
in accordance with instructions of Sun's management, to reflect more moderate
growth in synergy revenues and lower operating margins on those synergy revenues
during the forecast period. J.P. Morgan also calculated a range of terminal
asset values of RCA's synergies with Sun at the end of the forecast period
ending December 31, 2001 by applying a perpetual growth rate ranging from 3.0%
to 4.0% to the unlevered free cash flows of RCA's synergies with Sun during the
final year of the five-year period. The unlevered free cash flows from RCA's
synergies with Sun and the range of terminal asset values of RCA's synergies
with Sun were then discounted to present values using a range of discount rates
from 10.0% to 11.0%, which were chosen by J.P. Morgan based upon an analysis of
the weighted average cost of capital of RCA.
 
        EQUITY VALUE RANGE ON A DISCOUNTED CASH FLOW BASIS:  Based on the
adjusted financial projections prepared by the management of RCA described under
"--Stand-Alone Value" and a discount rate of 10.5%, the Discounted Cash Flow
analysis of RCA, including the potential revenue and cost synergies with Sun,
indicated a range of equity values between $13.00 and $20.00 per share of RCA
Common Stock.
 
        COMBINED INDICATED RANGE OF EQUITY VALUES (STAND-ALONE BASIS PLUS
SYNERGIES).  Overall, the three valuation methodologies described herein
indicated a range of equity values between $13.00 and $21.00 per share of RCA
Common Stock on a stand-alone basis, including synergies.
 
    The summary set forth above does not purport to be a complete description of
the analyses or data presented by J.P. Morgan. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description. J.P. Morgan believes that the summary set forth
above and their analyses must be considered as a whole and that selecting
portions thereof, without considering all of its analyses, could create an
incomplete view of the processes underlying its analyses and opinion. The
preparation of fairness opinions does not involve a mathematical evaluation or
weighing of the results of the individual analyses performed, but requires J.P.
Morgan to exercise its professional judgment--based on its experience and
expertise--in considering a wide variety of analyses taken as a whole. Each of
the analyses conducted by J.P. Morgan was carried out in order to provide a
different perspective on the transaction and to add to the total mix of
information available. J.P. Morgan did not form a conclusion as to whether any
individual analysis, considered in isolation, supported or failed to support an
opinion as to fairness. Rather, in reaching its conclusion, J.P. Morgan
considered the results of the analyses in light of each other and ultimately
reached its conclusion based on the results of all analyses taken as a whole.
J.P. Morgan based its analyses on assumptions that it deemed reasonable,
including assumptions concerning general business and economic conditions and
industry-specific factors. The other principal assumptions upon which J.P.
Morgan based its analyses are set forth above under the description of each such
analysis. J.P. Morgan's analyses are not necessarily indicative of actual values
or actual future results that might be achieved, which values may be higher or
lower than those indicated. Moreover, J.P. Morgan's analyses are not and do not
purport to be appraisals or otherwise reflective of the prices at which
businesses actually could be bought or sold.
 
    As a part of its investment banking business, J.P. Morgan and its affiliates
are continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, investments for passive and control
purposes, negotiated underwritings, secondary distributions of listed and
unlisted securities, private placements, and valuations for estate, corporate
and other purposes. J.P. Morgan was selected to deliver an opinion to Sun's
board of directors with respect to the RCA Merger on the basis of such
experience and its familiarity with Sun.
 
    For services rendered in connection with and including the delivery of its
opinions on the RCA Merger, Sun has agreed to pay J.P. Morgan an engagement fee
of $250,000 payable upon execution of the engagement letter dated February 6,
1997, as amended April 3, 1998, and agreed to pay J.P. Morgan a fee
 
                                       93
<PAGE>
of $1,850,000 (including the $250,000 engagement fee) payable upon consummation
of the RCA Merger. In addition, Sun has agreed to reimburse J.P. Morgan for its
expenses incurred in connection with its services, including the fees and
disbursements of counsel, and will indemnify J.P. Morgan against certain
liabilities, including liabilities arising under the Federal securities laws.
 
    J.P. Morgan and its affiliates maintain banking and other business
relationships with Sun and its affiliates, for which it receives customary fees.
In the ordinary course of their businesses, affiliates of J.P. Morgan may
actively trade the debt and equity securities of Sun or RCA for their own
accounts or for the accounts of customers and, accordingly, they may at any time
hold long or short positions in such securities.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion summarizes the material federal income tax
consequences of the RCA Merger to RCA and holders of RCA Capital Stock. The
discussion is based on current law and reflects the opinions of Shearman &
Sterling, special tax counsel to Sun, and Rogers & Hardin LLP, counsel to RCA.
The discussion does not address aspects of federal taxation other than income
taxation, nor does it address all aspects of federal income taxation, including,
without limitation, aspects of federal income taxation that may be applicable to
particular shareholders, such as shareholders who are dealers in securities,
foreign persons or those who acquired their RCA Capital Stock in a compensation
transaction. The discussion also does not address the federal income tax
consequences of the RCA Merger to holders of options or warrants to purchase RCA
Capital Stock. In addition, it does not address the state, local or foreign tax
consequences of the RCA Merger, if any.
 
    HOLDERS OF RCA CAPITAL STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS WITH
RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE RCA
MERGER.
 
    The material federal income tax consequences of the RCA Merger to RCA and
the holders of RCA Capital Stock will be as follows: (i) the RCA Merger will
qualify as a "reorganization" within the meaning of Section 368 of the Code;
(ii) no gain or loss will be recognized by RCA in the RCA Merger; (iii) no gain
or loss will be recognized by holders of RCA Capital Stock upon their receipt of
Sun Common Stock or Sun Preferred Stock, as the case may be, in exchange for
their RCA Capital Stock, except that holders of RCA Capital Stock who receive
cash proceeds in lieu of fractional shares of Sun Common Stock will recognize
gain or loss equal to the difference, if any, between such proceeds and the tax
basis of RCA Capital Stock allocated to their fractional share interests; (iv)
such gain or loss, if any, will constitute capital gain or loss if the
fractional share interests exchanged are held as capital assets at the time of
the RCA Merger; (v) such capital gain or loss will be long-term capital gain or
loss if the holding period for the fractional share interests (including the
holding period of RCA Capital Stock attributed thereto as described below)
exceeds one year; (vi) the tax basis of Sun Common Stock or Sun Preferred Stock,
as the case may be, received by holders of RCA Capital Stock will be the same as
the tax basis of the RCA Capital Stock exchanged therefor less the tax basis, if
any, allocated to fractional share interests; and (vii) the holding period of
Sun Common Stock or Sun Preferred Stock, as the case may be, in the hands of
holders of RCA Capital Stock will include the holding period of their RCA
Capital Stock exchanged therefor, provided that such RCA Capital Stock is held
as a capital asset at the time of the RCA Merger.
 
    The material federal income tax consequences of the RCA Merger to Sun will
be that no gain or loss will be recognized by Sun in the RCA Merger.
 
    It is a condition to Sun's and RCA's obligations to effect the RCA Merger
that Sun and RCA shall each have received opinions (the "Tax Opinions") from
their respective tax counsel, Shearman & Sterling and Rogers & Hardin LLP, which
Tax Opinions shall not have been withdrawn or modified in any material respect,
to the effect that, on the basis of certain representations, and subject to
certain assumptions and limitations stated in the Tax Opinions, the RCA Merger
will qualify as a tax-free reorganization under Section 368 of the Code and that
each of Sun, RCA Merger Sub and RCA will be a party to the reorganization within
the meaning of Section 368(b) of the Code.
 
                                       94
<PAGE>
    No ruling has been or will be obtained from the Internal Revenue Service
with respect to the RCA Merger. The Tax Opinions are not binding on the Internal
Revenue Service or the courts, and no assurance can be given that the Internal
Revenue Service would not be able to successfully challenge the conclusions
expressed in the Tax Opinions.
 
    Payments in respect of RCA Capital Stock may be subject to informational
reporting to the Internal Revenue Service and to a 31% back-up withholding tax.
Back-up withholding will not apply, however, to a payment to a holder of RCA
Capital Stock or other payee if such holder or payee completes and signs the
substitute Form W-9 that will be included as part of the transmittal letter or
otherwise proves to Sun and the RCA Exchange Agent that it is exempt from
back-up withholding.
 
LIMITATIONS ON RESALES BY AFFILIATES
 
    All shares of Sun Common Stock and Sun Preferred Stock received by RCA
shareholders in the RCA Merger will be freely transferable, except that shares
of Sun Common Stock and Sun Preferred Stock received by persons who are deemed
to be "affiliates" of RCA prior to the RCA Merger may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act of 1933, as amended (the "Securities Act"), (or Rule 144 in
the case of such persons who become affiliates of Sun) or otherwise in
compliance with (or pursuant to an exemption from) the registration requirements
of the Securities Act. Persons deemed to be "affiliates" of RCA or Sun are those
individuals or entities that control, are controlled by, or are under common
control with, such party and generally include executive officers and directors
of such party as well as certain principal shareholders of such party. Under
guidelines published by the Commission, the sale or other disposition of Sun
Common Stock or RCA Common Stock by an affiliate of either Sun or RCA, as the
case may be, within 30 days prior to the RCA Effective Time or the sale or other
disposition of Sun Common Stock or Sun Preferred Stock thereafter prior to the
publication of financial results that include at least 30 days of post-merger
combined operations of Sun and RCA could preclude pooling of interests
accounting treatment of the RCA Merger. See "--Accounting Treatment." The RCA
Merger Agreement requires RCA to use all reasonable efforts to cause each of its
affiliates to execute a written agreement to the effect that such person will
not offer or sell or otherwise dispose of any of the shares of Sun Common Stock
and Sun Preferred Stock issued to such person in or pursuant to the RCA Merger
except in compliance with the Securities Act and the rules and regulations
promulgated by the Commission thereunder. This Joint Proxy Statement/Prospectus/
Information Statement does not cover any resales of Sun Common Stock or Sun
Preferred Stock received by affiliates of RCA in the RCA Merger. See "The RCA
Merger Agreement--Agreements of RCA Affiliates."
 
ACCOUNTING TREATMENT
 
    The RCA Merger is expected to be treated as a "pooling of interests" for
accounting purposes. This accounting method permits the recorded assets and
liabilities of both Sun and RCA to be carried forward to the Surviving RCA
Corporation at their recorded historical amounts and no recognition of goodwill
in the combination is required of either company in the RCA Merger.
 
    It is a condition to each party's obligation to effect the RCA Merger that
Sun and RCA receive opinions from Arthur Andersen LLP, the independent public
accountants of Sun, based upon certain material facts and certain
representations and warranties described in such opinion, to the effect that
pooling of interests accounting treatment for the RCA Merger is appropriate. In
the event that a substantial number of the shareholders of RCA properly exercise
their dissenters' rights, the RCA Merger may not qualify for treatment as a
pooling of interests under applicable accounting rules and Sun's independent
public accountants may not be able to render an opinion regarding such
qualification. Under the RCA Merger Agreement, each party's obligation to
consummate the RCA Merger is conditioned on the delivery of such opinion;
therefore, the inability of Sun's independent public accountants to deliver such
opinion would entitle either party to abandon the RCA Merger. Neither Sun nor
RCA intends to waive this condition.

INTERESTS OF CERTAIN PERSONS IN THE RCA MERGER
 
    In considering the recommendation of the RCA board of directors with respect
to the RCA Merger Agreement and the transactions contemplated thereby, holders
of RCA Capital Stock should be aware that certain members of RCA's management
and of the RCA board of directors have interests in the RCA Merger that are in
addition to the interests of RCA's shareholders in general. These interests
arise from, among other things, certain employment agreements and benefit plans,
settlement of certain outstanding litigation and indemnification arrangements
and certain other matters which Sun has agreed to assume after the RCA Merger.
 
    As of December 31, 1997, directors and executive officers of RCA
beneficially owned (i) 4,910,321 shares of RCA Common Stock for which they will
receive the same consideration as other RCA shareholders and (ii) unexercised
options to acquire 1,099,152 shares of RCA Common Stock, which will be treated
as described below under "--RCA OPTION GRANTS."
 
    EMPLOYMENT AGREEMENTS.  RCA and two of its wholly-owned subsidiaries entered
into employment agreements with Philip M. Rees, General Counsel of RCA, John R.
Mack, Senior Vice President of Capital Care Management Company, and Jeffrey
Andrews, President of Retirement Management Corporation. Each agreement provides
for certain payments to the officer party thereto upon termination of such
officer's employment prior to the expiration of the term of such agreement by
RCA or the relevant subsidiary without "cause" (as defined therein) or by the
officer with "good reason," which is defined as (i) the assignment to such
officer of duties and responsibilities inconsistent with such officer's
positions, duties, responsibilities, titles or offices; (ii) any material
reduction by RCA of such officer's duties or responsibilities; (iii) any
reduction by RCA of such officer's compensation or benefits (unless such
reduction is made with respect to all senior management); or (iv) requiring such
officer to be based at a location not within reasonable commuting distance of
Atlanta, Georgia. In the event that any such officers is terminated by Sun other
than for "cause" or any such officer terminates his employment for "good
reason," and subject to each such officer compliance with the terms of his
employment agreement, each such officer will have the right thereafter to
receive such officer's salary and benefits enumerated in such officer's
employment agreement for the remainder of the term. Under such conditions, in
the event of such termination, Mr. Rees would be entitled to receive an annual
salary of $200,000 until July 1, 1998, $225,000 until July 1, 1999, $247,500
until July 1, 2000, and, as a result of RCA's failure prior to May 1, 1998 to
notify Mr. Rees of the termination, contingent on consummation of the RCA
Merger, of his employment agreement, $272,250 until July 1, 2001, immediately
vested and exercisable nonqualified stock options to purchase 25,000 shares of
RCA Common Stock during each year of the employment agreement, and certain other
benefits; Mr. Mack would be entitled to receive an annual salary of $192,000
until June 30, 1998, and $212,000 until June 30, 1999, immediately vested and
exercisable nonqualified stock options to purchase 25,000 shares of RCA Common
Stock during each year of the employment agreement, and certain other benefits;
and Mr. Andrews would be entitled to receive an annual salary of $180,000 until
July 1, 1998, and $220,000 until July 1, 1999, immediately vested and
exercisable nonqualified stock options to purchase 50,000 shares of RCA Common
Stock during each year of the employment agreement, and certain other benefits.
Any stock option granted pursuant to such employment agreements will expire five
years from the date of grant.
 
    RCA OPTION GRANTS.  As provided in the RCA Merger Agreement, by virtue of
the RCA Merger, each option or warrant granted by RCA to purchase shares of RCA
Common Stock which is outstanding and unexercised immediately prior to the RCA
Effective Time will be assumed by Sun and converted into an option or warrant to
purchase shares of Sun Common Stock in such number and at such exercise price as
is described in the RCA Merger Agreement. As of May 1, 1998, employees (or
former employees) of RCA held RCA options to purchase an aggregate of 1,437,171
shares of RCA Common Stock at a weighted average exercise price of $6.77 per
share (at exercise prices ranging from $4.647 to $15.95 per share). Approval of
the RCA Merger Agreement by the Sun stockholders will constitute stockholder
approval of the assumption by Sun of the rights and obligations of option plans
of RCA and of the amendment of such plans to provide for, among other things,
the conversion at the RCA Effective Time of
 
                                       96
<PAGE>
each outstanding option and warrant of RCA into an option or warrant to purchase
shares of Sun Common Stock. See "The RCA Merger Agreement--Options and Warrants
to Purchase RCA Common Stock."
 
    INDEMNIFICATION; INDEMNIFICATION AGREEMENTS.  Under the RCA Merger
Agreement, Sun has agreed that the articles of incorporation and bylaws of the
Surviving RCA Corporation will contain the indemnification provisions set forth
in RCA's articles of incorporation and bylaws and that such provisions will not
be amended, repealed or otherwise modified for a period of six years from the
RCA Effective Time in any manner that would adversely affect the rights
thereunder of individuals who at the RCA Effective Time were directors,
officers, employees, fiduciaries, or agents of RCA. However, the Surviving RCA
Corporation may amend or otherwise modify the provisions with respect to
indemnification that are set forth in its articles of incorporation and bylaws
to exclude any right to indemnification thereunder with respect to any civil or
criminal penalties, damages, fines, disgorgement or other similar personal
liabilities, or any injunctions or consent decrees, incurred, imposed or entered
into in connection with any claim, action, suit, proceeding or investigation,
whether civil, criminal, administrative or investigative, brought or assessed by
any United States federal, state or local or any foreign governmental regulatory
or administrative authority, agency or commission or any settlement thereof
("Excluded Items."). Sun has also agreed that from and after the RCA Effective
Time, Sun and the Surviving RCA Corporation shall indemnify and hold harmless
each present and former director and officer of RCA against (i) any costs or
expenses (including reasonable attorneys' fees) and (ii) judgments, fines,
losses, claims, damages or liabilities, but excluding from this clause (ii)
Excluded Items.
 
    SETTLEMENT ARRANGEMENTS.  Between August 25, 1997 and October 24, 1997, ten
putative class action lawsuits were filed in the United States District Court
for the Northern District of Georgia on behalf of the persons who purchased RCA
Common Stock, naming RCA and certain of its officers and directors as
defendants. On November 25, 1997, RCA, Sun and representatives of the plaintiffs
entered into the MOU, pursuant to which Sun has agreed to pay $9 million into
the Escrow Account maintained by Sun to settle the Actions. RCA also agreed to
assign coverage under its directors' and officers' liability insurance policy
for these specific claims to the plaintiffs. The Settlement is contingent upon
the closing of the RCA Merger and confirmatory discovery and is subject to the
execution of definitive documentation and court approval. Upon satisfaction of
the conditions precedent to the Settlement, all claims by the class that were or
could have been asserted by the plaintiffs against RCA or any of the other
defendants in the Actions will be settled and released and the Actions will be
dismissed in their entirety with prejudice in exchange for the release of all
funds from the Escrow Account to the plaintiffs. Court approval of the
Settlement will not be sought until after the closing of the RCA Merger. See
"Risk Factors--Risk Factors Concerning RCA and Contour--Shareholder Litigation"
and "--Background of the Mergers."
 
    LOAN EXTENSION.  On January 10, 1997, Sun loaned RCA $9,750,000 in order to
enable RCA to cause the repayment of certain indebtedness incurred by Contour in
connection with Contour's acquisition of Atlantic Medical Supply Company, Inc.
("Atlantic") on August 6, 1996. Consistent with RCA's bank line of credit in
effect on such date, the loan is unconditionally and irrevocably guaranteed by
Christopher F. Brogdon and Edward E. Lane. On July 10, 1997, Sun and RCA amended
the terms of the loan to: (i) increase the applicable interest rate by 2.0%;
(ii) extend the maturity date to 120 days after the termination of the RCA
Merger Agreement; and (iii) replace the collateral securing the loan with a
second lien on all of RCA's accounts receivable. On July 10, 1997, Sun also
agreed to loan RCA an additional $5,000,000, which loan is also secured by a
second lien on all of RCA's accounts receivable and is unconditionally and
irrevocably guaranteed by Messrs. Brogdon and Lane. The additional $5,000,000
loan was funded on July 15, 1997. See "--Loan Agreements."
 
LOAN AGREEMENTS
 
    On January 10, 1997, Sun loaned RCA $9,750,000 (the "Sun Loan") in order to
enable RCA to cause the repayment of certain indebtedness incurred by Contour in
connection with Contour's acquisition of Atlantic on August 6, 1996 (the
"Atlantic Note"). The Atlantic Note, which was due on January 10, 1997,
 
                                       97
<PAGE>
provided that, if an event of default occurred or continued, the Atlantic Note
would have been convertible, at the option of the holder, into shares of RCA
Common Stock at a 15% discount to the market price. The Sun Loan was made
because Sun and RCA were then engaged in discussions concerning the RCA Merger,
and each party desired to prevent the Atlantic Note from going into default
while the parties were engaged in such discussions. RCA loaned the proceeds it
received from Sun to Contour (the "RCA Loan") and simultaneously converted the
RCA Loan into 1,950,000 shares of Contour Common Stock. Contour then satisfied
the Atlantic Note with the funds it received from the RCA Loan. In addition,
Contour agreed to pay RCA a fee of $500,000 in consideration for RCA's guarantee
of the Atlantic Note, which was satisfied by Contour's issuance of an additional
100,000 shares of Contour Common Stock in lieu of cash. Contour's issuance of
the 100,000 shares of Contour Common Stock was not related to the Sun Loan or
the RCA Loan. Each of these transactions was authorized and approved by the
boards of directors of RCA and Contour. The RCA Loan was converted into
1,950,000 shares of Contour Common Stock because RCA believed that the
conversion ratio was favorable to RCA and that RCA would derive considerable
long-term value from its ownership of the Contour Common Stock.
 
    The Sun Loan was made pursuant to a promissory note dated as of January 10,
1997 (the "RCA Note"). On July 10, 1997, Sun and RCA amended the terms of the
Sun Loan to: (i) increase the applicable interest rate by 2.0%; (ii) extend the
maturity date; and (iii) replace the collateral securing the loan with a second
lien on all of RCA's accounts receivable. The RCA Note bears interest at a rate
of 11% per annum, and will increase to 15% per annum in the event of a default.
The outstanding principal and interest under the RCA Note is due at maturity at
the close of business on the 120th day after the termination of the RCA Merger
Agreement. The pledge agreement securing the outstanding principal and interest
under the RCA Note was amended and restated effective July 10, 1997 to provide
that the RCA Note would be secured by a lien on RCA's accounts receivable. The
lien on the accounts receivable was junior to the lien securing RCA's bank line
of credit in effect on such date. The RCA Note provided that it is an event of
default if the aggregate amount of indebtedness outstanding thereunder is not
secured by accounts receivable aged less than 120 days and which are not due
from affiliates of RCA ("Eligible Accounts") at least equal to 150% of such
indebtedness, less the aggregate principal amount of indebtedness outstanding
under RCA's bank line of credit in effect on such date and the Additional Loan
referred to below. The amendment to the terms of the loan also added certain
subsidiaries of RCA as additional borrowers or guarantors under the RCA Note,
and such subsidiaries entered into pledge agreements on substantially similar
terms as the amended and restated Pledge Agreement entered into by RCA.
Consistent with RCA's bank line of credit in effect on such date, the RCA Note
is also unconditionally and irrevocably guaranteed by Christopher F. Brogdon and
Edward E. Lane.
 
    On July 10, 1997, Sun agreed to lend RCA an additional $5,000,000 (the
"Additional Loan"), which loan was funded on July 15, 1997. The Additional Loan
is also secured by a second lien on all of RCA's accounts receivable which lien
was subordinate to the lien securing RCA's bank line of credit in effect on such
date to the same extent as the lien securing the Sun Loan. The Additional Loan
bears interest at a rate of 12% per annum and will increase to 16% per annum in
the event of a default. The outstanding principal and interest under the
Additional Loan is also due at maturity at the close of business on the 120th
day after the termination of the RCA Merger Agreement. The Additional Loan
provided that it is an event of default if the aggregate amount of indebtedness
outstanding thereunder is not secured by Eligible Accounts or other collateral
having an aggregate fair market value at least equal to 100% of such
indebtedness, less the aggregate principal amount of indebtedness outstanding
under RCA's bank line of credit in effect on such date and the RCA Note. The
subsidiaries which are additional borrowers or guarantors under the RCA Note are
also additional borrowers or guarantors under the Additional Loan, and have
entered into security agreements on substantially similar terms as the pledge
agreements securing the RCA Note. The Additional Loan is also unconditionally
and irrevocably guaranteed by Christopher F. Brogdon and Edward E. Lane on
substantially similar terms as their guarantee of the RCA Note.
 
    On December 15, 1997, HCFP Funding, Inc. ("HCFP"), RCA and certain of its
subsidiaries of RCA entered into a loan and security agreement, pursuant to
which HCFP granted to RCA and certain of its
 
                                       98
<PAGE>
subsidiaries a $14 million revolving line of credit (the "HCFP Loan"). The HCFP
Loan replaced RCA's previous bank line of credit, is secured by a first priority
lien on all of RCA's accounts receivable, and bears interest at a rate of prime
plus 2%. Outstanding principal and interest under the HCFP Loan are due on
December 15, 2001. Sun and HCFP have entered into an agreement whereby Sun
agreed to subordinate the indebtedness outstanding under the Sun Loan and the
Additional Loan, and the liens securing such indebtedness to the liens securing
the HCFP Loan and not to accelerate the indebtedness outstanding under the Sun
loan or the Additional Loan in the event of an event of default thereunder until
the later of (i) the 20th day after such event of default and (ii) July 31, 1998
without HCFP's prior written consent.
 
    Effective as of December 15, 1997, each of the Sun Loan and the Additional
Loan were amended to provide that it is an event of default thereunder if the
aggregate amount of indebtedness thereunder is not secured by Eligible Accounts
at least equal to 100% of such indebtedness, plus, in the case of the Additional
Loan, the aggregate fair market value of any other collateral pledged to Sun,
less, in each case, the aggregate principal amount outstanding under the HCFP
Loan and the Additional Loan (in the case of the Sun loan) or the Sun Loan (in
the case of the Additional Loan).
 
    Each of the Sun Loan and the Additional Loan requires RCA to provide Sun
with monthly reports regarding RCA's compliance with the collateral coverage
provisions of such loans. As of the date of this Joint Proxy
Statement/Prospectus/Information Statement, RCA is in violation of such
collateral reporting requirements. Sun has not yet determined what action, if
any, it will take in the event that such violations are not cured to Sun's
satisfaction.
 
MANAGEMENT AGREEMENT
 
    On July 15, 1997, Sun and RCA entered into an agreement (the "Management
Agreement") pursuant to which Sun agreed to provide management, consulting and
advisory services to RCA with respect to all 16 long-term care facilities (the
"Facilities") operated by RCA in Virginia and North Carolina. As payment for
providing such services, Sun will receive a monthly management fee equal to
seven percent of the gross revenues of the Facilities. The Management Agreement
also authorizes Sun to cause its therapy services and pharmaceutical
subsidiaries to provide such ancillary services to the Facilities at costs not
in excess of those that would be charged to RCA by an unrelated third party in
an arm's-length transaction. RCA has agreed to indemnify Sun with respect to any
investigations, actions or proceedings on the part of regulatory authorities
involving any of the Facilities. The Management Agreement will terminate on the
earlier to occur of the RCA Effective Time, 120 days after the termination of
the RCA Merger Agreement, or the repayment of the Additional Loan.
 
ANCILLARY SERVICE AGREEMENTS
 
    The RCA Merger Agreement provides that neither Sun nor RCA shall terminate,
and each shall cause its affiliates and the affiliates of the shareholders of
RCA party to the RCA Stock Option Agreement not to terminate, until 14 days
after termination of the RCA Merger Agreement (after which either party may
terminate) any contracts relating to the provision or receipt of pharmacy
products or services, therapy or supplies ("Ancillary Services") that RCA any of
its affiliates or any affiliates of the shareholders of RCA party to the RCA
Stock Option Agreement have entered into with Sun or any of its affiliates. With
regard to RCA's facilities that do not, as of November 25, 1997, receive all of
their required Ancillary Services from Sun or Sun's affiliates, RCA shall, and
shall cause its affiliates and the affiliates of the shareholders of RCA party
to the RCA Stock Option Agreement to, promptly take all reasonable action,
including, without limitation, terminating existing contracts with other
providers of Ancillary Services in accordance with the terms thereof, to cause
all such facilities to begin receiving all of their required Ancillary Services
from Sun or Sun's affiliates as soon as practicable after November 25, 1997.
 
REGULATORY MATTERS
 
    Under the HSR Act and the rules promulgated thereunder by the FTC, certain
acquisition transactions may not be consummated unless notice has been given and
certain information has been furnished to
 
                                       99
<PAGE>
the Antitrust Division and the FTC and specified waiting period requirements
have been satisfied. Sun and RCA each first filed with the Antitrust Division
and the FTC a Notification and Report Form (an "HSR Notice") with respect to the
RCA Merger on April 28, 1997. The required waiting period under the HSR Act was
terminated early and thus expired on May 16, 1997. However, Sun's and RCA's
first HSR Notices expired on May 16, 1998. Accordingly, Sun and RCA each filed
additional HSR Notices, for which the waiting period expired on May 20, 1998. At
any time before or after the RCA Effective Time, the FTC or the Antitrust
Division could take such action under the antitrust laws as it deems necessary
or desirable in the public interest, including seeking to enjoin the RCA Merger
or seeking the divestiture of RCA by Sun, in whole or in part, or the
divestiture of substantial assets of Sun, RCA, or their respective subsidiaries.
State attorneys general and private parties may also bring legal actions under
the federal or state antitrust laws under certain circumstances.
 
OPERATIONS FOLLOWING THE RCA MERGER
 
    Sun plans to integrate promptly the operations, facilities and personnel of
Sun and RCA following the RCA Merger. The general result will be to combine
administrative organizations with a reduced headcount and overhead structure and
to eliminate duplicative or unnecessary corporate functions. RCA's corporate
headquarters in Atlanta, Georgia will be closed as soon as practicable after the
RCA Effective Time, which should lead to a significant reduction in costs and,
most importantly, allow Sun to quickly and more completely integrate operations.
Sun will assume management of all RCA operations upon completion of the RCA
Merger. None of the directors or executive officers of RCA is expected to
continue in the management of the combined operations following the RCA
Effective Time. Sun also intends to terminate all of RCA's contracts with
In-House following the RCA Effective Time. Costs to be incurred in connection
with the Mergers are expected to be significant and would be charged against
earnings of the combined company. The charge is currently estimated to be
approximately $30 million, and is expected to consist of transaction costs and
integration expenses, including elimination of redundant corporate functions,
severance costs related to headcount reductions, the write-off of certain
intangibles and property and equipment and the settlement of the Actions (see
"Risk Factors--Risk Factors Concerning RCA and Contour--Shareholder
Litigation"). Approximately $25 million of the estimated charges relating to the
integration expenses are expected to be charged to operations in the fiscal
quarter in which the RCA Merger is consummated. Approximately $5 million of the
estimated charges are expected to be expensed as incurred, as these costs are
expected to benefit future combined operations. Pursuant to the MOU entered into
by RCA, Sun and representatives of the plaintiffs in the Actions, Sun has agreed
to pay $9 million into an interest-bearing account to settle the Actions. The
Settlement will be expensed upon resolution of the conditions to the MOU. These
amounts are preliminary estimates only and are therefore subject to change. In
addition, there can be no assurance that Sun will not incur additional charges
in subsequent quarters to reflect costs associated with the Mergers. The
components of the charges are expected to be as follows:

DISSENTERS' RIGHTS
 
    A holder of RCA Series AA Preferred Stock and RCA Series F Preferred Stock
(together the "RCA Preferred Stock") who complies with the provisions of Article
113 of the Colorado Business Corporation
 
                                      100
<PAGE>
Act (the "Business Corporation Act") has the right to receive a cash payment for
his or her shares of RCA Preferred Stock instead of receiving the shares of Sun
Common Stock or Sun Preferred Stock, as the case may be, offered pursuant to the
RCA Merger Agreement. The holders of RCA Common Stock do not have dissenters'
rights under Article 113 of the Business Corporation Act. The following summary
of the provisions of Article 113 is not intended to be a complete statement of
such provisions and is qualified in its entirety to the full text of Article
113, a copy of which is attached to this Joint Proxy Statement/
Prospectus/Information Statement as Appendix C, and incorporated herein by
reference. RCA shareholders are urged to consult legal counsel with respect to
dissenters' rights.
 
    Shareholders of a Colorado corporation have the right, in certain
circumstances, to dissent from certain corporate actions, including the
consummation of a plan of merger by a Colorado corporation which requires the
approval of such corporation's shareholders, whether or not such dissenting
shareholder has the right to vote with respect to such corporate actions.
Shareholders entitled to dissent are also entitled to obtain a cash payment in
the amount of the fair value of their shares. The holders of RCA Preferred Stock
have such rights with respect to the RCA Merger.
 
    A holder of RCA Preferred Stock who wishes to assert dissenters' rights
under Article 113 must (i) cause RCA to receive, before the vote is taken with
respect to the RCA Merger, written notice of the holder's intention to demand a
cash payment for the holder's shares of RCA Preferred Stock if the RCA Merger is
effectuated; and (ii) not vote the shares of RCA Preferred Stock in favor of the
RCA Merger. A holder of RCA Preferred Stock failing to satisfy these
requirements will not be entitled to dissenters' rights under Article 113.
 
    If the RCA Merger is approved, RCA must give a written dissenters' notice to
all RCA shareholders who are entitled to demand a cash payment for their shares
under Article 113 (the "RCA Dissenters' Notice") within ten days after
shareholder approval of the RCA Merger. The RCA Dissenters' Notice must: (i)
state that the RCA Merger was authorized and state the effective date or the
proposed effective date of the RCA Merger; (ii) state an address at which it
will receive cash payment demands and the address of a place where certificates
for certificated shares must be deposited; (iii) supply a form for demanding a
cash payment, which form shall request a dissenter to state an address to which
a cash payment is to be made; (iv) set the date by which it must receive a cash
payment demand and certificates for uncertificated shares, which date may not be
less than 30 days after the date that the RCA Dissenters' Notice is given; (v)
state the requirement regarding the dissent by record holders with respect to
shares held by beneficial owners, as permitted by Section 7-113-103(3) of the
Business Corporation Act; and (vi) be accompanied by a copy of Article 113.
 
    An RCA shareholder who wishes to obtain a cash payment for his or her shares
of RCA Preferred Stock must demand a cash payment by submitting the form
provided pursuant to (iv) above, or by stating such demand in another writing,
and depositing the shareholder's certificate(s) for certificated shares. RCA may
restrict the transfer of any shares not represented by a certificate from the
date the demand for cash payment is received. The shareholder demanding a cash
payment in accordance with Section 7-113-204 shall retain all rights of a
shareholder, except the right to transfer shares, until the effective date of
the RCA Merger. An RCA shareholder who does not provide demand for a cash
payment by the dates set forth in the RCA Dissenters' Notice and in accordance
with Section 7-113-204 will not be entitled to a cash payment for his or her
shares of RCA Preferred Stock as provided in the Business Corporation Act.
 
    Pursuant to Sections 7-113-206 and 207 of the Business Corporation Act, upon
the effective date of the RCA Merger or upon receipt of a cash payment demand,
whichever is later, RCA must pay each dissenter who complied with Section
7-113-204 the amount of cash that RCA estimates to be the fair market value of
the shares, plus accrued interest. The cash payment must be accompanied by (i)
certain financial information regarding RCA; (ii) a statement of RCA's estimate
of the fair value of the shares; (iii) an explanation of how the interest was
calculated; (iv) a statement of the dissenter's right to demand a cash payment
under Section 7-113-209; and (v) a copy of Section 7-113-206 of the Business
Corporation Act.
 
                                      101
<PAGE>
    Section 7-113-208 of the Business Corporation Act permits RCA to require
each shareholder to certify in writing, or in the dissenter's cash payment
demand, whether or not the dissenter acquired beneficial ownership of his or her
shares of RCA Preferred Stock before the date of the first announcement to the
news media or to the shareholders, such date to be set forth in the dissenters'
notice. If any dissenter does not so certify in writing, RCA may offer to make a
cash payment if the dissenter agrees to accept such payment in full satisfaction
of the demand for a cash payment.
 
    A dissenter may give written notice to RCA, within 30 days after RCA makes
or offers a cash payment for the dissenter's shares of RCA Preferred Stock, of
the dissenter's estimate of the fair value of such shares and of the amount of
interest due and may demand cash payment of such estimate, or reject RCA's offer
under Section 7-113-208 and demand a cash payment of the fair value of the
shares and interest due if: (i) the dissenter believes that the amount of cash
paid pursuant to Section 7-113-206 or offered pursuant to Section 7-113-208 is
less than the full value of his or her shares of RCA Preferred Stock or that the
interest due was incorrectly calculated; (ii) RCA fails to make a cash payment
as required under Section 7-113-206 within the time specified above; or (iii)
RCA does not return the deposited certificates as required by Section 7-113-207.
Dissenters who do not give the required notice waive the right to demand a cash
payment under Section 7-113-209.
 
    If a demand for a cash payment under Section 7-113-209 remains unresolved,
RCA may, within 60 days after receiving the cash payment demand, petition the
court to determine the fair value of the shares of RCA Preferred Stock and
accrued interest. All dissenters whose demands remain unsettled would be made a
party to such a proceeding. Each dissenter is entitled to judgment for the
amount the court finds to be the fair value of the shares of RCA Preferred
Stock, plus interest, less any amount paid by RCA. The costs associated with
this proceeding shall be assessed against RCA, unless the court finds that all
or some of the dissenters acted arbitrarily, vexatiously, or not in good faith
in demanding cash payment under Section 7-113-209, in which case the court may
assess the costs in the amount the court finds equitable against some or all of
the dissenters. The court may also assess the fees and expenses of counsel and
experts for the respective parties in amounts the court finds equitable, against
RCA or the dissenters. If RCA does not commence a proceeding within the 60-day
period, it must pay each dissenter whose demand remains unsettled the amount of
cash demanded.
 
EXCHANGE OF SHARES
 
    At or prior to the RCA Effective Time, Sun will appoint, and will retain for
a period of at least six months after the RCA Effective Time, an exchange agent
(the "RCA Exchange Agent") to effect the exchange of shares of RCA Capital Stock
for Sun Common Stock and Sun Preferred Stock in connection with the RCA Merger.
From time to time after the RCA Effective Time, Sun shall deposit, or cause to
be deposited, certificates representing Sun Common Stock and Sun Preferred Stock
for conversion of shares of RCA Capital Stock in accordance with the RCA Merger
Agreement.
 
    Commencing immediately after the RCA Effective Time and until the
appointment of the RCA Exchange Agent is terminated, each holder of a
certificate or certificates theretofore evidencing shares of RCA Capital Stock
may surrender the same to the RCA Exchange Agent, and, after the appointment of
the RCA Exchange Agent has been terminated, any such holder may surrender any
such certificate to Sun. Such holder will be entitled upon such surrender to
receive in exchange therefor a certificate or certificates representing the
number of full shares of Sun Common Stock, or Sun Preferred Stock, as the case
may be, into which the shares of RCA Capital Stock theretofore represented by
the certificate or certificates so surrendered have been converted pursuant to
the Merger, together with a cash payment in lieu of fractional shares, if any,
and all such shares of Sun Common Stock, or Sun Preferred Stock, as the case may
be, will be deemed to have been issued at the RCA Effective Time. Until so
surrendered and exchanged, each outstanding certificate which, prior to the RCA
Effective Time, represented issued and outstanding shares of RCA Capital Stock
will be deemed for all corporate purposes of Sun, other than the payment of
dividends and other distributions, if any, to evidence ownership of the number
of full shares of Sun
 
                                      102
<PAGE>
Common Stock, or Sun Preferred Stock, as the case may be, into which the shares
of RCA Capital Stock theretofore represented thereby have been converted at the
RCA Effective Time.
 
    Until certificates representing shares of RCA Capital Stock are surrendered,
no dividend or other distribution, if any, payable to the holders of record of
Sun Common Stock, or Sun Preferred Stock, as the case may be, as of any date
subsequent to the RCA Effective Time will be paid to the holder of such
certificate. Upon the surrender of any such certificate representing shares of
RCA Capital Stock, however, the record holder of the certificate or certificates
representing shares of Sun Common Stock, or Sun Preferred Stock, as the case may
be, issued in exchange therefor will receive from the RCA Exchange Agent or from
Sun, as the case may be, payment of the amount of dividends and other
distributions, if any, which as of any date subsequent to the RCA Effective Time
and until such surrender will have become payable with respect to such number of
shares of Sun Common Stock, or Sun Preferred Stock, as the case may be. No
interest will be payable with respect to the payment of any such presurrender
dividends upon the surrender of certificates theretofore representing shares of
RCA Capital Stock.
 
    No fractional share certificates for Sun Common Stock will be issued upon
the surrender for exchange of certificates evidencing shares of RCA Capital
Stock. In lieu thereof, the RCA Exchange Agent or Sun, as the case may be, will
pay each holder of RCA Capital Stock an amount in cash calculated as provided in
the RCA Merger Agreement.
 
    Risk of loss and title to certificates representing shares of RCA Capital
Stock will pass only upon proper delivery of such certificates to the RCA
Exchange Agent.
 
    Sun shall deposit, or cause to be deposited, certificates representing Sun
Common Stock and Sun Preferred Stock for conversion of shares of RCA Capital
Stock in accordance with the RCA Merger Agreement.
 
    At the RCA Effective Time, the stock transfer books of RCA with respect to
shares of RCA Capital Stock will each be closed, and there will be no further
registration of transfers of shares of RCA Capital Stock thereafter on the
records of any such stock transfer books. In the event of a transfer of
ownership of shares of RCA Capital Stock that is not registered in the stock
transfer records of RCA, at the RCA Effective Time, a certificate or
certificates representing the number of full shares of Sun Common Stock or Sun
Preferred Stock, as the case may be, into which such shares of RCA Capital Stock
have been converted will be issued to the transferee together with a cash
payment in lieu of fractional shares, if any, and a cash payment in the amount
of any presurrender dividends, if any, if the certificate or certificates
representing such shares of RCA Capital Stock is or are properly surrendered as
described above, accompanied by all documents required to evidence and effect
such transfer and by evidence of payment of any applicable stock transfer tax.

                            THE RCA MERGER AGREEMENT
 
    The description of the RCA Merger Agreement contained in this Joint Proxy
Statement/Prospectus/ Information Statement is qualified in its entirety by
reference to the complete text of the RCA Merger Agreement, as amended by
Amendment No. 1 thereto dated as of May 27, 1997, Amendment No. 2 thereto dated
as of August 21, 1997, Amendment No. 3 thereto dated as of November 25, 1997 and
Amendment No. 4 thereto dated as of April 3, 1998, copies of which are attached
hereto as Appendices A, A-1, A-2, A-3 and A-4, respectively, and are
incorporated herein by reference.
 
RCA EFFECTIVE TIME
 
    The RCA Merger will become effective by the filing of a certificate of
merger (the "RCA Certificate of Merger") with the Secretary of State of the
State of Colorado. However, there can be no assurance that the conditions to the
RCA Merger will be satisfied or that the RCA Merger Agreement will not be
terminated.
 
CORPORATE MATTERS
 
    At the RCA Effective Time the articles of incorporation and by-laws of RCA
Merger Sub, as in effect immediately prior to the RCA Effective Time, will
become the articles of incorporation and by-laws of the Surviving RCA
Corporation, and the officers and directors of RCA Merger Sub immediately prior
to the RCA Effective Time will become the initial officers and directors of the
Surviving RCA Corporation.
 
CONVERSION OF SECURITIES
 
    At the RCA Effective Time, by virtue of the RCA Merger and without any
action on the part of Sun, RCA Merger Sub, RCA, the holders of RCA Capital Stock
or the holders of common stock, par value $.0001 per share, of RCA Merger Sub,
(i) each share of RCA Common Stock and Series AA Preferred Stock issued and
outstanding immediately prior to the RCA Effective Time will be converted into
shares of Sun Common Stock as described above under "The RCA Merger--Conversion
of RCA Capital Stock," (ii) each share of RCA Series F Preferred Stock will be
exchanged for one share of Sun Preferred Stock and (iii) each share of common
stock, par value $.0001 per share, of RCA Merger Sub issued and outstanding
immediately prior to the RCA Effective Time and all rights in respect thereof
will forthwith cease to exist and will be converted into and become exchangeable
for one newly and validly issued, fully paid and nonassessable share of common
stock of the Surviving RCA Corporation.
 
OPTIONS AND WARRANTS TO PURCHASE RCA COMMON STOCK
 
    At the RCA Effective Time, each option or warrant granted by RCA to purchase
shares of RCA Common Stock which is outstanding and unexercised immediately
prior to the RCA Effective Time will be assumed by Sun and converted into an
option or warrant to purchase shares of Sun Common Stock in such number and at
such exercise price as described below and otherwise having the same terms and
conditions as in effect immediately prior to the RCA Effective Time (except to
the extent that such terms, conditions and restrictions may be altered in
accordance with their terms as a result of the RCA Merger). The number of shares
of Sun Common Stock to be subject to the new option or warrant will be equal to
the product of (i) the number of shares of RCA Common Stock subject to the
original option or warrant multiplied by (ii) the RCA Common Exchange Ratio. The
exercise price per share of Sun Common Stock under the new option or warrant
will be equal to the quotient of (i) the exercise price per share of RCA Common
Stock under the original option or warrant divided by (ii) the RCA Common
Exchange Ratio. Upon each exercise of options or warrants by a holder thereof,
the aggregate number of shares of Sun Common Stock deliverable upon such
exercise will be rounded down, if necessary, to the nearest whole share and the
aggregate exercise price will be rounded up, if necessary, to the nearest cent.
 
                                      104

                                      105

institute, file or commence any claim, action, suit or proceeding. In addition,
the RCA Merger Agreement provides that Sun may not sell, transfer, license or

NOTICES OF CERTAIN EVENTS
 
    The RCA Merger Agreement provides that each of Sun and RCA must give prompt
notice to the other of (i) any notice or other communication from any person
alleging that the consent of such person is or may be required in connection
with the RCA Merger; (ii) any notice or other communication from any
governmental entity in connection with the RCA Merger; (iii) any actions, suits,
claims, investigations or proceedings commenced or, to its knowledge, threatened
against, relating to or involving or otherwise affecting Sun or RCA that relate
to the consummation of the RCA Merger; (iv) the occurrence of a default or event
that, with the giving of notice or lapse of time or both, would become a default
under any material contract of such party; (v) any change that could reasonably
be expected to have a material adverse effect on RCA or Sun or to delay or
impede the ability of either RCA or Sun to perform its obligations pursuant to
the RCA Merger Agreement and to effect the consummation of the RCA Merger; and
(vi) the receipt by certain officers of RCA of notice from any creditor that any
account payable in excess of $35,000 is past due and that as a result of such
past due account such creditor has interrupted, suspended or terminated, or
threatened to interrupt, suspend or terminate, the provision of goods or
services to RCA.
 
ACCESS TO INFORMATION; CONFIDENTIALITY
 
    The RCA Merger Agreement provides that, from the date of the RCA Merger
Agreement to the RCA Effective Time, each of Sun and RCA must (i) provide to the
other access at reasonable times to its officers, employees, agents, properties,
offices and other facilities and to the books and records thereof and (ii)
furnish promptly such information concerning its and its subsidiaries' business,
properties, contracts, assets, liabilities and personnel as the other party may
reasonably request. In addition, the obligations of Sun and RCA under the
confidentiality agreements entered into between them as of November 12, 1996 and
December 20, 1996 remain in effect.
 
NO SOLICITATION OF TRANSACTIONS
 
    Pursuant to the RCA Merger Agreement, RCA may not, directly or indirectly,
solicit, initiate or knowingly encourage (including by way of furnishing
nonpublic information), or take any other action knowingly to facilitate, any
inquiries or the making of any proposal or offer (including, without limitation,
any proposal or offer to its shareholders) that constitutes, or may reasonably
be expected to lead to, any Competing Transaction (as described below), or enter
into or maintain or continue discussions or negotiate with any person in
furtherance of such inquiries or to obtain a Competing Transaction, or agree to
or endorse any Competing Transaction, or authorize or permit any of RCA's
officers, directors or employees,
 
                                      106
<PAGE>
or any investment banker, financial advisor, attorney, accountant or other
representative retained by RCA, to take any such action. However, the RCA Merger
Agreement provides that the board of directors of RCA may (i) comply with Rule
14e-2 promulgated under the Exchange Act with regard to a tender or exchange
offer and (ii) after receiving the advice of outside counsel to the effect that
RCA's board of directors is required to do so in order to discharge properly its
fiduciary duties, consider, negotiate, approve and recommend to its shareholders
an unsolicited BONA FIDE written acquisition proposal which (A) was not received
in violation of the RCA Merger Agreement, (B) if executed or consummated would
be a Competing Transaction, (C) is not subject to financing and (D) RCA's board
of directors determines in good faith, after the receipt of an opinion of its
financial advisor, would result in a transaction more favorable to RCA's
shareholders than the RCA Merger (any such acquisition proposal, a "Superior
Proposal"). The RCA Merger Agreement requires that RCA must notify Sun and RCA
Merger Sub promptly if any proposal or offer, or any inquiry or contact with any
person with respect thereto, regarding such an acquisition proposal or a
Competing Transaction is made.
 
    For purposes of the RCA Merger Agreement, "Competing Transaction" means,
with respect to RCA, (i) any merger, consolidation, share exchange, business
combination or other similar transaction; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of 15 percent or more of the
assets of RCA, in a single transaction or series of transactions; (iii) any
tender offer or exchange offer for 25 percent or more of the outstanding voting
securities of RCA or the filing of a registration statement under the Securities
Act in connection therewith; (iv) any person having acquired beneficial
ownership or the right to acquire beneficial ownership of, or any "group" (as
such term is defined under Section 13(d) of the Exchange Act) having been formed
which beneficially owns or has the right to acquire beneficial ownership of, 25
percent or more of the outstanding voting securities of RCA; (v) any
solicitation in opposition to the approval of the RCA Merger Agreement by the
shareholders of RCA; or (vi) any public announcement of a proposal, plan or
intention to do any of the foregoing or any agreement to engage in any of the
foregoing.
 
POOLING OF INTERESTS
 
    The RCA Merger Agreement provides that none of the parties thereto may
knowingly take or fail to take any action, other than those required by the RCA
Merger Agreement, which action could reasonably be expected to jeopardize the
treatment of the RCA Merger as a "pooling of interests" for accounting purposes,
and each party is obligated to take all reasonable actions necessary to cause
the RCA Merger to be characterized as such.
 
PLAN OF REORGANIZATION
 
    The RCA Merger Agreement is intended to constitute a tax-free "plan of
reorganization" within the meaning of the income tax regulations promulgated
under the Code. Pursuant to the RCA Merger Agreement, RCA and Sun have agreed
that, from and after the date of the RCA Merger Agreement, they will use all
reasonable efforts to cause the RCA Merger to qualify, and will not knowingly
take any actions or cause any actions to be taken which could reasonably be
expected to prevent the RCA Merger from qualifying, as a tax-free reorganization
under the Code. In the event that the RCA Merger fails to qualify as a tax-free
reorganization under the Code, RCA and Sun have agreed to negotiate in good
faith to restructure the RCA Merger so that it will qualify as a tax-free
transaction under the Code.
 
FURTHER ACTION; CONSENTS; FILINGS
 
    The RCA Merger Agreement provides that each of RCA and Sun must use all
reasonable efforts to (i) take, or cause to be taken, all appropriate action,
and do, or cause to be done, all things necessary, proper or advisable under
applicable law or otherwise to consummate and make effective the RCA Merger,
(ii) obtain from governmental entities any consents, licenses, permits, waivers,
approvals, authorizations or orders required to be obtained or made by Sun, RCA
Merger Sub, RCA or the Surviving RCA
 
                                      107
<PAGE>
Corporation in connection with the authorization, execution and delivery of the
RCA Merger Agreement and the consummation of the RCA Merger and (iii) make all
necessary filings, and thereafter make any other required or appropriate
submissions, with respect to the RCA Merger Agreement and the RCA Merger
required under the rules and regulations of the NYSE, the Securities Act, the
Exchange Act and any other applicable federal or state securities laws and any
other applicable law. RCA and Sun are also required to promptly give any notices
regarding the RCA Merger, the RCA Merger Agreement or the transactions
contemplated thereby to third parties required under applicable law or by any
contract, license, lease or other agreement to which it is bound, and to use all
reasonable efforts to obtain any third party consents required under any such
contract, license, lease or other agreement in connection with the consummation
of the RCA Merger or the other transactions contemplated by the RCA Merger
Agreement.
 
NYSE LISTING
 
    RCA and Sun have each agreed to use all reasonable efforts to obtain, prior
to the RCA Effective Time, the approval for listing on the NYSE, effective upon
official notice of issuance, of the shares of Sun Common Stock into which the
shares of RCA Capital Stock will be converted pursuant to the RCA Merger.
 
AGREEMENTS OF RCA AFFILIATES
 
    Rule 145 promulgated under the Securities Act regulates the disposition of
securities of "affiliates" of RCA in connection with the RCA Merger. RCA has
delivered to Sun a letter (the "Affiliate Letter") identifying each person who
was, in RCA's reasonable judgment, at the RCA Record Date, an "affiliate" of RCA
for purposes of Rule 145 under the Securities Act. RCA has also agreed to use
all reasonable efforts to cause each person (an "Affiliate") who is identified
as an Affiliate in the Affiliate Letter to deliver to Sun, prior to the RCA
Effective Time, a written agreement (an "Affiliate Agreement"). Under such
Affiliate Agreements, every Affiliate will represent that he or she has been
advised that the Affiliate may not sell, transfer or otherwise dispose of Sun
Capital Stock issued to the Affiliate in the RCA Merger unless such sale,
transfer or other disposition (i) has been registered under the Securities Act,
(ii) is made in compliance with the requirements of Rule 145 under the
Securities Act, or (iii) in the opinion of counsel reasonably acceptable to Sun,
is otherwise exempt from registration under the Securities Act.
 
    In addition, all executive officers and directors of RCA have confirmed that
they intend to vote their respective shares of RCA Capital Stock in favor of the
RCA Merger. They have also agreed to restrict sales of such shares prior to and
following the RCA Merger to comply with the requirements of pooling-of-interests
accounting treatment.
 
DIRECTORS' AND OFFICERS' INDEMNIFICATION
 
    Under the RCA Merger Agreement, Sun has agreed that the articles of
incorporation and bylaws of the Surviving RCA Corporation in the RCA Merger will
contain the indemnification provisions set forth in RCA's articles of
incorporation and bylaws and that such provisions will not be amended, repealed
or otherwise modified for a period of six years from the RCA Effective Time in
any manner that would adversely affect the rights thereunder of individuals who
at the RCA Effective Time were directors, officers, employees, fiduciaries, or
agents of RCA. However, the Surviving RCA Corporation may amend or otherwise
modify the provisions with respect to indemnification that are set forth in its
articles of incorporation and bylaws to exclude any right to indemnification
thereunder with respect to any civil or criminal penalties, damages, fines,
disgorgement or other similar personal liabilities, or any injunctions or
consent decrees, incurred, imposed or entered into in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, brought or assessed by any United States
federal, state or local or any foreign governmental, regulatory or
administrative authority, agency or commission or any settlement thereof
("Excluded Items"). Sun has also agreed that from and after the
 
                                      108
<PAGE>
RCA Effective Time, Sun and the Surviving RCA Corporation shall indemnify and
hold harmless each present and former director and officer of RCA against (i)
any costs or expenses (including reasonable attorneys' fees) and (ii) judgments,

or prior to the RCA Effective Time, whether asserted or claimed prior to, at or
after the RCA Effective Time, to the extent permitted under the charter
documents of RCA or Sun.

             THE RCA STOCKHOLDERS' STOCK OPTION AND PROXY AGREEMENT
 
    Concurrent with the execution of the RCA Merger Agreement and as a condition
to the willingness of Sun to enter into the RCA Merger Agreement, Sun entered
into a Stockholders' Stock Option and Proxy Agreement, dated as of February 17,
1997, as amended by Amendment No. 1 thereto dated as of November 25, 1997 (as
amended, the "RCA Stock Option Agreement"), with Christopher F. Brogdon, Connie
Brogdon, Edward E. Lane, Darrell C. Tucker and Winter Haven Homes, Inc. (each a
"Stockholder" and, together, the "Stockholders"), collectively owners as of such
date of approximately 36% of the outstanding shares of RCA Capital Stock.
Pursuant to the RCA Stock Option Agreement, each Stockholder (i) granted to Sun
an irrevocable option to purchase such Stockholder's shares at a price equal to
$10.00 per share of RCA Common Stock and RCA Series F Preferred Stock, and
$10.00 per share of RCA Series AA Preferred Stock under certain circumstances
and (ii) agreed to vote, and granted to Sun an irrevocable proxy to vote, all
voting securities of RCA held by such Stockholder in favor of approval of the
RCA Merger Agreement and the RCA Merger.
 
    The following description of the RCA Stock Option Agreement is qualified in
its entirety by reference to the complete text of the RCA Stock Option
Agreement, a copy of which is attached as Exhibit 1.00(a) to the RCA Merger
Agreement attached hereto as Appendix A and incorporated herein by reference.
 
    Pursuant to the RCA Stock Option Agreement, each Stockholder granted to Sun
an option (the "RCA Stock Option") to purchase such Stockholder's RCA Common
Stock (the "RCA Option Shares"), the RCA Option Shares in the aggregate
representing approximately 36% of the shares of RCA Capital Stock issued and
outstanding on the date of grant, at a purchase price of $10.00 per share of RCA
Common Stock and RCA Series AA Preferred Stock, and $9.00 per share of RCA
Series F Preferred Stock (the "RCA Option Purchase Price").
 
    Sun may exercise the RCA Stock Option, in whole or in part, at any time
following the earlier of (i) the termination of the RCA Merger Agreement (other
than a termination due to a final and nonappealable judgment preventing the RCA
Merger) and (ii) the first occurrence of a Competing Transaction until the
expiration of the RCA Stock Option.
 
    The RCA Stock Option Agreement provides that, in the event Sun wishes to
exercise the RCA Stock Option, it must send a written notice to the Stockholder
who granted the option specifying the place and date, not later than ten
business days and not earlier than three business days following the date of
such notice, for closing such purchase. If Sun exercises any such RCA Stock
Options, the Stockholder who granted such option must execute and deliver
further transfers, assignments, endorsements, consents and other instruments as
Sun may reasonably request for the purpose of effectively carrying out the
options. At the closing, Sun must pay the aggregate RCA Option Purchase Price
for the shares of RCA Capital Stock being purchased from each Stockholder by
delivery of a number of shares of Sun Common Stock equal to the quotient of the
total amount of the RCA Option Purchase Price and the average of the last
reported sales prices of one share of Sun Common Stock on the NYSE during the
period of the 20 most recent trading days ending five business days before the
date of such notice. Each such Stockholder must deliver to Sun a certificate or
certificates evidencing such Stockholder's shares of RCA Capital Stock to be
purchased by Sun, free and clear of any liens, and each Stockholder will receive
a certificate or certificates evidencing the shares of Sun Common Stock to be
received by each Stockholder at closing.
 
    The RCA Stock Option Agreement provides that, during the term of the RCA
Stock Options, each Stockholder shall not (i) sell, pledge or otherwise dispose
of any of its shares of RCA Capital Stock, (ii) deposit its shares of RCA
Capital Stock into a voting trust or enter into a voting agreement with respect
to such shares, or (iii) enter into any contract, option or other arrangement or
undertaking with respect to the direct or indirect acquisition or sale,
assignment, transfer or other disposition of any RCA Capital Stock. On June 4,
1997, Ms. Brogdon sold 101,871 shares of RCA Common Stock (representing
approximately two percent of the shares of RCA Capital Stock subject to the
option) in apparent violation of the RCA Stock Option Agreement. According to
documents filed by Ms. Brogdon with the Commission in
 
                                      113
<PAGE>
connection with such sale, such shares were sold pursuant to Rule 144 of the
Securities Act at a price of $10.0023 per share. Sun has not yet determined what
action, if any, it will take in response to such transaction.
 
    The RCA Stock Option Agreement further provides that each Stockholder, with
respect to those shares of RCA Capital Stock that it owns of record, appoints
Sun, or any nominee of Sun, during the term of the RCA Stock Options, as its
true and lawful proxy, to vote all of the shares of RCA Capital Stock held by
each Stockholder at every annual, special or adjourned meeting of the
shareholders of RCA (i) in favor of the adoption of the RCA Merger Agreement and
approval of the RCA Merger and any other transactions contemplated by the RCA
Merger Agreement, (ii) against any proposal for any recapitalization, merger,
sale of assets or other business combination between RCA and any other person or
entity (other than the RCA Merger) or any other action or agreement that would
result in a breach of any covenant, representation or warranty or any other
obligation or agreement of RCA under the RCA Merger Agreement or which could
result in any of the conditions to RCA's obligations under the RCA Merger
Agreement not being fulfilled, and (iii) in favor of any other matter relating
to consummation of the transactions contemplated by the RCA Merger Agreement.
Each Stockholder further agreed to cause the shares of RCA Capital Stock owned
by it beneficially to be voted in accordance with the RCA Stock Option
Agreement.
 
    The RCA Stock Option Agreement also provides that Sun shall, within three
months following the closing, file with the Commission a shelf registration
statement relating to the resale of the shares of Sun Common Stock issuable upon
exercise of an RCA Stock Option by the Stockholders from time to time in
accordance with the methods of distribution set forth in such shelf registration
statement, and shall use its best efforts to cause such shelf registration
statement to be declared effective under the Securities Act as soon as
practicable thereafter. Sun is also required to use its best efforts to keep the
shelf registration statement continuously effective for up to two years
following the closing.
 
    The RCA Stock Option Agreement also provides that for a period of 30 days
after the consummation of a Competing Transaction involving RCA, Sun shall have
the right, upon five business days' prior written notice, to cause RCA (or any
successor in interest to RCA by merger, sale of all or substantially all of the
assets, or otherwise) to repurchase from Sun all or any unexercised portion of
the RCA Stock Options, and all or any portion of the shares of RCA Capital Stock
acquired by Sun pursuant to the exercise of any RCA Stock Options, for an
aggregate price equal to the sum of the following amounts for each class of RCA
Capital Stock: (A) the product of the number of shares of such class as to which
the RCA Stock Options remain exercisable multiplied by the amount by which the
value of the per share consideration paid for such class in the Competing
Transaction exceeds the RCA Option Purchase Price for such class; and (B) the
product of the number of shares of such class that Sun owns as a result of the
exercise of an RCA Stock Option and the per share consideration paid for such
class in the Competing Transaction.
 
    The RCA Stock Option Agreement will expire by its terms (i) if the RCA Stock
Options are not exercised prior to the close of business on the 14th day
following termination of the RCA Merger Agreement, (ii) if the RCA Merger
Agreement is terminated due to entry of a final and nonappealable judgment
preventing consummation of the RCA Merger, or (iii) if the RCA Merger Agreement
is terminated or terminable due to Sun's uncured breach of any representation,
warranty, covenant or agreement.

<PAGE>
                               THE CONTOUR MERGER
 
GENERAL
 
    The Contour Merger Agreement provides that Contour Merger Sub will be merged
with and into Contour. As a result of the Contour Merger, the separate corporate
existence of Contour Merger Sub will cease and Contour will continue as the
surviving corporation of the Contour Merger (the "Surviving Contour
Corporation") and will become a direct wholly-owned subsidiary of Sun. The
Contour Merger will take place as promptly as practicable after the adoption and
approval of the Contour Merger Agreement and the approval of the Contour Merger
by the stockholders of Sun and Contour, and the satisfaction or waiver of the
other conditions to the Contour Merger set forth in the Contour Merger
Agreement. See "The Contour Merger Agreement." It is expected that the Contour
Merger will occur immediately prior to the consummation of the RCA Merger.
 
CONVERSION OF CONTOUR CAPITAL STOCK
 
    At the Contour Effective Time, by virtue of the Contour Merger and without
any action on the part of Sun, Contour Merger Sub, Contour or the holders of
Contour Capital Stock, each share of Contour Capital Stock (as defined below)
issued and outstanding immediately prior to the Contour Effective Time (other
than any shares of Contour Capital Stock to be canceled as described below and
any dissenting shares) and all rights in respect thereof will forthwith cease to
exist and will be converted into and become exchangeable for the number of
shares of Sun Common Stock (and associated Preferred Share Purchase Rights)
described below.
 
    CONTOUR COMMON STOCK.  Each outstanding share of Contour Common Stock, other
than shares owned by RCA, will be converted into the number of shares of Sun
Common Stock equal to the quotient of $8.50 divided by the average of the last
reported sales prices of one share of Sun Common Stock on the NYSE during the
period of the 20 most recent trading days ending on the fifth business day prior
to the Contour Effective Time (the "Sun Market Price") (the "Contour Common
Exchange Ratio").
 
    CONTOUR PREFERRED STOCK.  Each outstanding share of Contour Preferred Stock,
other than shares owned by RCA, will be converted into the number of shares of
Sun Common Stock equal to the quotient of $4.00 divided by the Sun Market Price
(the "Contour Preferred Exchange Ratio" and, together, with the Contour Common
Exchange Ratio, the "Contour Exchange Ratios").
 
    CONTOUR CAPITAL STOCK OWNED BY RCA.  Outstanding shares of Contour Capital
Stock owned by RCA will not be exchanged in the Contour Merger and will remain
outstanding. Notwithstanding the foregoing, if the RCA Merger does not occur
promptly after consummation of the Contour Merger, or if Sun does not undertake
to contribute to RCA all shares of Contour Capital Stock obtained by Sun
pursuant to the Contour Merger, RCA would receive the same per share
consideration as the other holders of Contour Capital Stock as set forth above.
 
    CONTOUR TREASURY STOCK.  Each share of Contour Capital Stock held in the
treasury of Contour and each share of Contour Capital Stock owned by Sun or any
direct or indirect wholly-owned subsidiary of Sun or of Contour immediately
prior to the Contour Effective Time will be canceled and extinguished without
any conversion thereof and no payment will be made with respect thereto.
 
    NO FRACTIONAL SHARES.  No fractional share certificates for Sun Common Stock
will be issued upon the surrender for exchange of certificates evidencing shares
of Contour Capital Stock. In lieu thereof, the Contour Exchange Agent or Sun, as
the case may be, will pay each holder of Contour Capital Stock an amount in cash
calculated as provided in the Contour Merger Agreement.
 
    OPTIONS AND WARRANTS.  At the Contour Effective Time, each option or warrant
granted by Contour to purchase shares of Contour Common Stock (each, a "Contour
Stock Option") which is outstanding and unexercised immediately prior to the
Contour Effective Time will be assumed by Sun and converted into
 
                                      115
<PAGE>
an option or warrant to purchase shares of Sun Common Stock in such number and
at such exercise price as follows and otherwise have the same terms and
conditions as in effect immediately prior to the Contour Effective Time: (i) the
number of shares of Sun Common Stock to be subject to the new option or warrant
will be equal to the product of (A) the number of shares of Contour Common Stock
subject to the original option or warrant and (B) the Contour Common Exchange
Ratio; (ii) the exercise price per share of Sun Common Stock under the new
option or warrant will be equal to the quotient of (A) the exercise price per
share of Contour Common Stock under the original option or warrant divided by
(B) the Contour Common Exchange Ratio; and (iii) upon each exercise of options
or warrants by a holder thereof, the aggregate number of shares of Sun Common
Stock deliverable upon such exercise shall be rounded down to the nearest whole
share and the aggregate exercise price shall be rounded up to the nearest cent.
Under the Contour Merger Agreement, Sun has agreed to file a registration
statement on Form S-8 with respect to the shares of Sun Common Stock subject to
Contour's Non-Qualified Stock Bonus Plan and 1996 Stock Option Plan following
the Contour Effective Time in order for such shares of Sun Common Stock to be
sold without restriction. The Contour Merger Agreement does not require Sun to
register the shares of Sun Common Stock issuable upon exercise of any warrants
assumed by Sun in the Contour Merger.
 
    CERTAIN ADJUSTMENTS.  If, between the date of the Contour Merger Agreement
and the Contour Effective Time, the outstanding shares of Contour Capital Stock
or Sun Common Stock are changed into a different number of shares by reason of
any reclassification, recapitalization, split-up, combination or exchange of
shares, or any dividend payable in stock or other securities is declared thereon
with a record date within such period or the number of shares of Contour Capital
Stock on a fully diluted basis is in excess of 9,454,693 shares (but excluding
options permitted to be issued pursuant to the Contour Merger Agreement), the
Contour Exchange Ratios will be adjusted accordingly to provide the holder of
Contour Capital Stock the same economic effect as contemplated by the Contour
Merger Agreement prior to such reclassification, recapitalization, split-up,
combination, exchange or dividend.
 
BACKGROUND OF THE CONTOUR MERGER
 
    See "The RCA Merger--Background of the Mergers" for a discussion of the
background of the Contour Merger.
 
SUN'S REASONS FOR THE CONTOUR MERGER; RECOMMENDATION OF SUN'S BOARD OF DIRECTORS
 
    The board of directors of Sun has carefully considered the advisability of
the Contour Merger, and believes that the terms of the Contour Merger Agreement
are fair to, and that the Contour Merger is in the best interests of, Sun's
stockholders. THE BOARD OF DIRECTORS OF SUN HAS UNANIMOUSLY APPROVED AND ADOPTED
THE CONTOUR MERGER AGREEMENT AND APPROVED THE CONTOUR MERGER, AND UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS OF SUN VOTE FOR THE APPROVAL AND ADOPTION OF
THE CONTOUR MERGER AGREEMENT AND APPROVAL OF THE CONTOUR MERGER AND THE ISSUANCE
OF SUN COMMON STOCK PURSUANT THERETO.
 
    In the course of its deliberations, the board of directors of Sun reviewed,
and consulted with Sun's management and its financial and legal advisors
concerning, a number of factors relevant to the Contour Merger. In particular,
the board of directors of Sun identified several potential benefits of the
Contour Merger to Sun and its stockholders, among other things:
 
    (i) the ability to extend Sun's position as a diversified healthcare company
by vertically integrating into the medical products business;
 
    (ii) the ability to supply affiliated facilities with medical products
distributed by Contour;
 
   (iii) the ability of Sun to achieve specific savings by reducing costs for
medical supplies through price discounts due to Sun's increased purchasing
volume following the Contour Merger;
 
    (iv) the ability of Sun to achieve revenue growth by distributing medical
supplies to nonaffiliated skilled nursing, assisted living and independent
living facilities;
 
                                      116
<PAGE>
    (v) the opportunities for economies of scale that may result from the
Contour Merger due to the combined purchasing power and medical supplies
requirements of the two companies;
 
    (vi) the written opinion of J.P. Morgan, dated February 17, 1997, that the
consideration to be paid by Sun in the Contour Merger is fair, from a financial
point of view, to Sun (see "--Opinion of Sun's Financial Advisor"), and J.P.
Morgan's indication at the November 25, 1997 Meeting of Sun's board of
directors, at which meeting the Sun board approved Amendment No. 2 to the
Contour Merger Agreement, that no event had occurred that would cause it to
withdraw such opinion (see "The RCA Merger-- Background of the Mergers");
 
   (vii) the potential to gain a competitive advantage in a consolidating
healthcare industry through improved market information and knowledge of patient
needs;
 
  (viii) the diversification of market risks inherent in the combination of the
two business entities;
 
    (ix) Contour's business, operations and prospects;
 
    (x) the terms and conditions of the Contour Merger Agreement;
 
    (xi) the historical market prices of, and other information with respect to,
the Sun Common Stock and the Contour Common Stock; and
 
   (xii) the prospects for the long-term performance of Sun Common Stock as well
as the potential volatility of such stock.
 
    The board of directors of Sun also considered a variety of inherent risks
and other potentially negative factors in its deliberations concerning the
Contour Merger. In particular, the board of directors of Sun considered, among
other things:
 
    (i) the potential dilutive effect of the issuance of Sun Common Stock
pursuant to the Contour Merger;
 
    (ii) the risk that the public market price of the Sun Common Stock might be
adversely affected by announcement of the Contour Merger; and
 
   (iii) the risks associated with integrating the operations of Contour with
Sun's existing operations, including the loss of key personnel and institutional
memory of Contour, difficulty in integrating corporate, accounting, financial
reporting and management information systems and strain on existing levels of
personnel to operate Contour's business (see "Risk Factors--Risk Factors
Concerning the Mergers-- Difficulty of Integrating Acquired Operations" and
"--Management of Growth");
 
    (iv) the risks associated with the assumption of Contour's existing
indebtedness in light of Sun's substantial indebtedness (see "Risk Factors--Risk
Factors Concerning Sun--Substantial Leverage; Ability to Service Debt");
 
    (v) the resignation of C&L as Contour's independent auditors, including
C&L's statement that its audit report on Contour's financial statements for the
fiscal year ended June 30, 1996 should not be relied upon because C&L concluded
that it could no longer rely on Contour management's representations (see "Risk
Factors--Risk Factors Concerning RCA and Contour--Resignation of Independent
Accountants; Restatement of Financial Statements");
 
    (vi) the restatement of Contour's financial statements for the fiscal year
ended June 30, 1996 and the first three quarters of fiscal 1997 and the
increased risk that the assumptions made by Sun regarding the financial
condition of Contour may later prove to be incorrect (see "Risk Factors--Risk
Factors Concerning RCA and Contour--Resignation of Independent Accountants;
Restatement of Financial Statements" and the "The RCA Merger--Background of the
Mergers");
 
                                      117
<PAGE>
   (vii) the significant deterioration of Contour's business and financial
condition since February 17, 1997 (see "Risk Factors--Risk Factors Concerning
RCA and Contour--Deterioration of Contour's Recent Financial Condition;
Noncompliance with Certain Covenants"); and
 
  (viii) other risks described above under "Risk Factors."
 
    In addition, the board of directors of Sun considered certain risks
associated with not consummating the RCA Merger, including the potential loss of
Contour as a supplier of medical products and services, the potential impairment
of the value of the Contour Debentures and the failure to obtain the potential
benefits of the Contour Merger. See "Risk Factors--Risk Factors Concerning the
Mergers--Adverse Effects of Failure to Consummate the Mergers--Sun."
 
    Although the board of directors of Sun did not receive quantitative analysis
of all of the factors listed above, based on the foregoing matters, and such
other matters as the members of the board of directors of Sun deemed relevant,
including the board's familiarity with the long-term care industry, the
recommendation of management of Sun and the conclusion of the board of directors
of Sun that the aggregate benefit of the positive factors described above
outweighed the aggregate negative detriment of the negative factors described
above, Sun's board of directors unanimously approved the Contour Merger
Agreement and the transactions contemplated thereby.
 
    The foregoing discussion of the information and factors considered and given
weight by the board of directors of Sun is not intended to be exhaustive but
includes all material factors considered by the board of directors of Sun. In
addition, in reaching the determination to approve and recommend the Contour
Merger Agreement and the transactions contemplated thereby, the board of
directors of Sun did not assign any relative or specific weights to the
foregoing factors which were considered, and individual directors may have given
differing weights to different factors.
 
CONTOUR'S REASONS FOR THE CONTOUR MERGER; RECOMMENDATION OF CONTOUR'S BOARD OF
  DIRECTORS
 
    The board of directors of Contour has carefully considered the advisability
of the Contour Merger, and believes that the terms of the Contour Merger
Agreement are fair to, and that the Contour Merger is in the best interests of,
Contour and its stockholders. THE BOARD OF DIRECTORS OF CONTOUR HAS UNANIMOUSLY
APPROVED AND ADOPTED THE CONTOUR MERGER AGREEMENT AND APPROVED THE CONTOUR
MERGER, AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF CONTOUR VOTE FOR THE
APPROVAL AND ADOPTION OF THE CONTOUR MERGER AGREEMENT AND APPROVAL OF THE
CONTOUR MERGER.
 
    In the course of its deliberations, the board of directors of Contour
reviewed, and consulted with Contour's management and its legal advisors
concerning, a number of factors relevant to the Contour Merger. In particular,
the board of directors of Contour identified several potential benefits of the
Contour Merger to Contour and its stockholders, among other things:
 
    (i) the consideration to be paid to Contour's stockholders pursuant to the
Contour Merger represents a 67% premium over the average of the closing prices
of the Contour Common Stock for the 30 trading days prior to the public
announcement of the Contour Merger (see "Opinion of Contour's Financial
Advisor");
 
    (ii) the fact that historically there has been only limited trading activity
and limited investor interest in the Contour Common Stock;
 
   (iii) the fact that Contour's majority stockholder, RCA (which is receiving
the same consideration as all other Contour stockholders in connection with the
Contour Merger), urged the Contour board to approve the Contour Merger and
recommend it to the Contour stockholders;
 
    (iv) the fact that Sun will own a majority of the outstanding shares of
Contour Common Stock upon consummation of the RCA Merger and, therefore, would
be able to subsequently "cash out" or "merge
 
                                      118
<PAGE>
out" Contour's minority holders on terms that may be less favorable to such
holders than the terms of the Contour Merger;
 
    (v) the desirability of eliminating possible conflicts of interest inherent
in the relationship between a parent company and its majority-owned subsidiary;
 
    (vi) Sun's market capitalization and public stock distribution will provide
Contour's stockholders with substantially increased liquidity;
 
   (vii) there is the possibility that Contour stockholders can benefit from an
increase in the price/ earnings multiple of the Sun Common Stock, which has
recently traded at price/earnings multiples below the industry averages, should
Sun's strategic direction and financial results result in the Sun Common Stock
trading at price/earnings multiples more in line with industry averages (see
"Opinion of Contour's Financial Advisor");
 
  (viii) Sun will have a greater diversification of revenue sources, and will
possess greater managerial, operational and financial resources, than does
Contour;
 
    (ix) Sun is expected to achieve certain administrative efficiencies and to
eliminate certain duplicate functions; and
 
    (x) Sun's greater financial resources should permit an acceleration of the
development and expansion of new business and services.
 
    In approving the Contour Merger Agreement and the transactions contemplated
thereby, and in recommending that Contour's stockholders approve the Contour
Merger, the Contour board of directors consulted with Contour management, as
well as its legal advisors, and also considered, among other things: (i) the
business, managerial expertise, business strategy, prospects and competitive
position of Contour and Sun; (ii) historical, current and projected financial
condition and results of operations of Contour (without giving effect to the
Contour Merger) and of Sun (after giving effect to the Contour Merger); (iii)
the requirement by Sun, as a condition to entering into the Contour Merger
Agreement, that RCA, which owned as of such date approximately 65% of the
outstanding shares of Contour Capital Stock, enter into, and the deleterious
effect on potential subsequent acquisition proposals of, the Contour Stock
Option Agreement; (iv) the fact that the Contour Merger Agreement permits
Contour to terminate the Contour Merger Agreement under certain circumstances if
a third party makes a bona fide proposal which is more favorable to Contour's
stockholders than the Contour Merger; (v) the consideration to be paid to
Contour stockholders and other terms of the Contour Merger Agreement; (vi) the
board's determination that it was unlikely that an alternative transaction could
be structured that would offer comparable value to Contour's stockholders; and
(vii) general economic and stock market conditions. In addition, on April 8,
1997, the Contour board of directors obtained the opinion of the investment
banking firm of Sterne, Agee & Leach, Inc. that, as of April 8, 1997, the
consideration to be received by Contour's stockholders in the Contour Merger was
fair, from a financial point of view, to the Contour stockholders. See
"--Opinion of Contour's Financial Advisor."
 
    The board of directors of Contour also considered a variety of inherent
risks and potentially negative factors in its deliberations concerning the
Contour Merger. In particular, the board of directors of Contour considered,
among other things: (i) the irreversible nature of the decision and the
consequent loss of independence; (ii) the possible change in certain existing
Contour corporate policies and strategies following the Contour Merger; (iii)
the other risks described under "Risk Factors"; and (iv) the potential for
post-merger dilution of Sun's earnings per share.
 
    The board of directors of Contour also considered certain risks associated
with not consummating the Contour Merger, including the loss of potential future
revenues from the provision of medical products and supplies to Sun, the
potential adverse impact on Contour's financial condition and results of
operations, and the failure to obtain the potential benefits of the Contour
Merger. See "Risk Factors--
 
                                      119
<PAGE>
Risk Factors Concerning the Mergers--Adverse Effects of Failure to Consummate
the Mergers-- Contour."
 
    Due to the wide variety of factors considered in connection with the
evaluation of the Contour Merger, Contour's board of directors did not find it
practicable to, and did not quantify or otherwise attempt to assign relative
weights to, the specific factors considered in reaching its determination. In
addition, individual members of Contour's board of directors may have given
different weight to different factors.
 
    CONTOUR BOARD RECOMMENDATION.  Contour's board of directors has approved the
Contour Merger Agreement and the transactions contemplated thereby and
determined that the Contour Merger is fair to, and in the best interests of,
Contour and its stockholders. AFTER CAREFUL CONSIDERATION, THE BOARD OF
DIRECTORS OF CONTOUR UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF CONTOUR
VOTE IN FAVOR OF THE CONTOUR MERGER AGREEMENT AND THE TRANSACTIONS CONTEMPLATED
THEREBY.
 
OPINION OF SUN'S FINANCIAL ADVISOR
 
    Pursuant to an engagement letter dated February 6, 1997, Sun retained J.P.
Morgan to deliver a fairness opinion in connection with the proposed Contour
Merger.
 
    On February 17, 1997, J.P. Morgan rendered its written opinion (the
inclusion of which in the Joint Proxy Statement/Prospectus/Information Statement
has been consented to by J.P. Morgan) to the board of directors of Sun that, as
of such date, the consideration to be paid by Sun in the proposed Contour Merger
was fair from a financial point of view to Sun. No limitations were imposed by
Sun's board of directors upon J.P. Morgan with respect to the investigations
made or procedures followed by it in rendering its opinions.
 
    THE FULL TEXT OF THE OPINION OF J.P. MORGAN, WHICH SETS FORTH THE
ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS
ATTACHED AS APPENDIX E TO THIS JOINT PROXY STATEMENT/PROSPECTUS/ INFORMATION
STATEMENT AND IS INCORPORATED HEREIN BY REFERENCE. SUN'S STOCKHOLDERS ARE URGED
TO READ THE OPINION IN ITS ENTIRETY. J.P. MORGAN'S OPINION IS ADDRESSED TO THE
BOARD OF DIRECTORS OF SUN, IS DIRECTED ONLY TO THE CONSIDERATION TO BE PAID IN
THE CONTOUR MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER
OF SUN AS TO HOW SUCH STOCKHOLDER SHOULD VOTE AT THE SUN SPECIAL MEETING. THE
SUMMARY OF THE OPINION OF J.P. MORGAN SET FORTH IN THIS JOINT PROXY
STATEMENT/PROSPECTUS/INFORMATION STATEMENT IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
    In arriving at its opinion, J.P. Morgan reviewed, among other things, a
draft of the Contour Merger Agreement; the audited financial statements of
Contour for the fiscal years ended June 30, 1995 and 1996, and the unaudited
financial statements of Contour for the period ended December 31, 1996; the
audited financial statements of Sun for the fiscal year ended December 31, 1995
and the unaudited financial statements of Sun for the fiscal year ended December
31, 1996; current and historical market prices of the Contour Common Stock;
certain publicly available information concerning the business of Contour and of
certain other companies engaged in businesses comparable to those of Contour,
and the reported market prices for certain other companies' securities deemed
comparable; publicly available terms of certain transactions involving companies
comparable to Contour and the consideration paid for such companies; the terms
of other business combinations deemed relevant by J.P. Morgan; certain internal
financial analyses and forecasts prepared by Sun and Contour and their
respective managements; and certain agreements with respect to outstanding
indebtedness or obligations of Sun and Contour. J.P. Morgan also held
discussions with certain members of the management of Sun and Contour with
respect to certain aspects of the Contour Merger, and the past and current
business operations of Sun and Contour, the financial condition and future
prospects and operations of Sun and Contour, and certain other matters believed
necessary or appropriate to J.P. Morgan's inquiry. In addition, J.P. Morgan
visited certain representative facilities of Contour, and reviewed such other
financial studies and analyses and considered such other information as it
deemed appropriate for the purposes of its opinion.
 
                                      120
<PAGE>
    J.P. Morgan relied upon and assumed, without independent verification, the
accuracy and completeness of all information that was publicly available or that
was furnished to it by Sun and Contour or otherwise reviewed by J.P. Morgan, and
J.P. Morgan has not assumed any responsibility or liability therefor. J.P.
Morgan has not conducted any valuation or appraisal of any assets or
liabilities, nor have any valuations or appraisals been provided to J.P. Morgan.
In relying on financial analyses and forecasts provided to J.P. Morgan, J.P.
Morgan has assumed that they have been reasonably prepared based on assumptions
reflecting the best currently available estimates and judgments by management as
to the expected future results of operations and financial condition of Sun and
Contour to which such analyses or forecasts relate.
 
    The projections furnished to J.P. Morgan for Sun and Contour were prepared
by the respective managements of each company. Neither Sun nor Contour publicly
discloses internal management projections of the type provided to J.P. Morgan in
connection with J.P. Morgan's analysis of the Contour Merger, and such
projections were not prepared with a view toward public disclosure. These
projections were based on numerous variables and assumptions that are inherently
uncertain and may be beyond the control of management, including, without
limitation, factors related to general economic and competitive conditions and
prevailing interest rates. Accordingly, actual results could vary significantly
from those set forth in such projections.
 
    J.P. Morgan's opinion is based on economic, market and other conditions as
in effect on, and the information made available to J.P. Morgan as of, the date
of such opinion. Subsequent developments may affect J.P. Morgan's opinion, and
J.P. Morgan does not have any obligation to update, revise, or reaffirm such
opinion. J.P. Morgan expressed no opinion as to the price at which the Sun
Common Stock will trade at any future time.
 
    In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinion. The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing its opinion.
 
    PUBLIC TRADING MULTIPLES.  Using publicly available information, J.P. Morgan
compared selected financial data of Contour with similar data for selected
publicly traded companies engaged in businesses that J.P. Morgan judged to be
analogous to Contour. The companies selected by J.P. Morgan were Gulf South
Medical, Physician Sales & Service, and Maxxim Medical. These companies were
selected, among other reasons, because they distribute medical supplies to
providers of long-term care to patients and operators of skilled nursing
facilities. For each comparable company, publicly available financial
performance through the twelve months ended September 30, 1996 was measured.
J.P. Morgan selected the mean value for each multiple, specifically: Firm Value
(Equity Value plus debt minus cash) to Last Twelve Months Revenues, Firm Value
to Last Twelve Months Earnings Before Interest and Taxes ("EBIT"), and Equity
Value (fully diluted equity multiplied by share price) to Projected 1997 Net
Income. The multiples for Firm Value to Last Twelve Months Revenues ranged from
1.1x to 2.2x with a mean of 1.5x. The multiples for Firm Value to LTM EBIT
ranged from 13.9x to 32.9x with a mean of 22.1x. The multiples for Equity Value
to Projected 1997 Net Income ranged from 11.3x to 38.6x with a mean of 24.9x.
These multiples were then applied to Contour's Last Twelve Months Revenues, Last
Twelve Months Earnings Before Interest and Taxes, and Projected 1997 Net Income
on a stand-alone basis (i.e., without synergies).
 
    SELECTED TRANSACTION ANALYSIS.  Using publicly available information, J.P.
Morgan examined selected transactions with respect to the medical supplies
industry. Specifically, J.P. Morgan reviewed the following transactions: Bergen
Brunswig's acquisition of Durr-Fillauer (September 1992), Physician Sales &
Services's acquisition of Taylor Medical (April 1995), Gulf South's acquisition
of L&M Medical (October 1995), Gulf South's acquisition of Bayer Medical
(February 1996), Contour's acquisition of AmeriDyne (March 1996), Contour's
acquisition of Atlantic Medical (August 1996), Gulf South's acquisition of
Gateway Healthcare (December 1996), and McKesson's acquisition of General
Medical (January 1997). J.P. Morgan focused on two transaction multiples for the
purposes of valuation: specifically, Firm Value to
 
                                      121
<PAGE>
Last Twelve Months Revenues and Firm Value to Last Twelve Months Earnings Before
Interest, Taxes, Depreciation, and Amortization ("EBITDA"). The multiples for
Firm Value to LTM Revenues ranged from 0.25x to 0.88x with a mean of 0.49x. The
multiples for Firm Value to LTM EBITDA ranged from 12.6x to 12.8x with a mean of
12.7x. These multiples were then applied to Contour's Pro Forma Last Twelve
Months Revenues and Contour's Pro Forma Last Twelve Months Earnings Before
Interest, Taxes, Depreciation, and Amortization on a stand-alone basis (i.e.,
without synergies).
 
    DISCOUNTED CASH FLOW ANALYSIS (STAND-ALONE BASIS).  J.P. Morgan conducted a
discounted cash flow analysis for the purpose of determining the fully diluted
equity value per share for the Contour Common Stock on a stand-alone basis
(i.e., without synergies). J.P. Morgan calculated the unlevered free cash flows
that Contour is expected to generate on a stand-alone basis during fiscal years
1997 through 2001 based upon financial projections prepared by the management of
Contour through the years ended December 31 and upon management projections
adjusted by J.P. Morgan to reflect more moderate growth in revenues and lower
operating margins during the five-year period, J.P. Morgan based its discounted
cash flow analysis on such adjusted projections and did not rely in any material
respect on the financial projections prepared by the management of Contour. J.P.
Morgan also calculated a range of stand-alone terminal asset values of Contour
at the end of the five-year period ending December 31, 2001 by applying a
perpetual growth rate ranging from 3.5% to 4.5% to the unlevered free cash flow
of Contour on a stand-alone basis during the final year of the five-year period.
The unlevered free cash flows on a stand-alone basis and the range of
stand-alone terminal asset values were then discounted to present values using a
discount rate of 10.5%, which was chosen by J.P. Morgan based upon an analysis
of the weighted average cost of capital of Contour. The present value of the
unlevered free cash flows on a stand-alone basis and the range of stand-alone
terminal asset values were then adjusted for Contour's estimated September 30,
1996 excess cash, option exercise proceeds and total debt.
 
    INDICATED RANGE OF EQUITY VALUES (STAND-ALONE BASIS).  The three valuation
methods described herein (Public Trading Multiples, Selected Transaction
Analysis, and Discounted Cash Flow Analysis), indicated an estimated range of
equity values for the Contour Common Stock of between $5.50 and $7.50 per share
on a stand-alone basis (i.e., without synergies).
 
    VALUATION OF SYNERGIES: DISCOUNTED CASH FLOW ANALYSIS.  J.P. Morgan also
conducted a discounted cash flow analysis for the purpose of determining the
fully diluted equity value per share for Contour's potential revenue and cost
synergies with Sun. J.P. Morgan calculated the unlevered free cash flows from
synergies that Contour is expected to generate during fiscal years 1997 through
2001 based upon financial projections prepared by the management of Sun and
Contour through the years ended December 31 and upon management projections
adjusted by J.P. Morgan to reflect more moderate growth in synergy revenues and
lower operating margins on those synergy revenues during the five-year period,
J.P. Morgan based its discounted cash flow analysis on such adjusted projections
and did not rely in any material respect on the financial projections prepared
by the management of Contour. J.P. Morgan also calculated a range of terminal
asset values of Contour's synergies with Sun at the end of the five-year period
ending December 31, 2001 by applying a perpetual growth rate ranging from 3.5%
to 4.5% to the unlevered free cash flows from Contour's synergies with Sun
during the final year of the five-year period. The unlevered free cash flows
from Contour's synergies with Sun and the range of terminal asset values of
Contour's synergies with Sun were then discounted to present values using a
range of discount rates from 10.0% to 11.0%, which were chosen by J.P. Morgan
based upon an analysis of the weighted average cost of capital of Contour. Based
on the adjusted management projections and a discount rate of 10.5%, the
discounted cash flow analysis of Contour's synergies with Sun indicated a range
of equity values between $4.00 and $5.00 per share of the Contour Common Stock.
 
    COMBINED INDICATED RANGE OF EQUITY VALUES (STAND-ALONE BASIS PLUS
SYNERGIES).  The estimated range of equity values for the Contour Common Stock
of between $5.50 and $7.50 on a stand-alone basis, as indicated by the three
valuation methodologies described herein, in addition to the indicated range of
 
                                      122
<PAGE>
equity values for Contour's synergies with Sun of between $4.00 and $5.00 per
share, as indicated by a discounted cash flow analysis of Contour's synergies
with Sun, resulted in a combined indicated range of equity values between $9.50
and $12.50 per share of the Contour Common Stock.
 
    BLENDED CONSIDERATION PAID BY SUN.  J.P. Morgan also noted the effective per
share price paid for Contour reflecting the $8.50 per share paid for the
publicly traded shares of Contour Common Stock and the per share value for
Contour embedded in the equity value of the purchase price of RCA. Through the
RCA Merger, Sun will acquire the 56.8% majority interest in Contour owned by RCA
at an effective price of $26,980,600, or $5.01 per share of Contour Common
Stock. This effective price reflects the consideration paid by Sun for RCA and
also reflects that the value of Contour (with synergies) represented 6.8% of the
total value of RCA (with synergies), as based on a Discounted Cash Flow
Analysis. The Discounted Cash Flow Analysis assumed a discount rate of 10.5% and
applied a growth rate of 4.0% to the unlevered free cash flow of Contour (with
synergies) and RCA (with synergies) during the forecast period. Pursuant to the
Contour Merger, Sun has agreed to purchase the remaining 43.2% of Contour's
equity at an effective price of $34,762,500 (assuming a price of $8.50 per
publicly traded share). The aggregate consideration paid by Sun for Contour is
$61,743,100, and the blended consideration is $6.52 per share.
 
    The summary set forth above does not purport to be a complete description of
the analyses or data presented by J.P. Morgan. The preparation of a fairness
opinion is a complex process and is not necessarily susceptible to partial
analysis or summary description. J.P. Morgan believes that the summary set forth
above and their analyses must be considered as a whole and that selecting
portions thereof, without considering all of its analyses, could create an
incomplete view of the processes underlying its analyses and opinion. The
preparation of fairness opinions does not involve a mathematical evaluation or
weighing of the results of the individual analyses performed, but requires J.P.
Morgan to exercise its professional judgment--based on its experience and
expertise--in considering a wide variety of analyses taken as a whole. Each of
the analyses conducted by J.P. Morgan was carried out in order to provide a
different perspective on the transaction and to add to the total mix of
information available. J.P. Morgan did not form a conclusion as to whether any
individual analysis, considered in isolation, supported or failed to support an
opinion as to fairness. Rather, in reaching its conclusion, J.P. Morgan
considered the results of the analyses in light of each other and ultimately
reached its conclusion based on the results of all analyses taken as a whole.
J.P. Morgan based its analyses on assumptions that it deemed reasonable,
including assumptions concerning general business and economic conditions and
industry-specific factors. The other principal assumptions upon which J.P.
Morgan based its analyses are set forth above under the description of each such
analysis. J.P. Morgan's analyses are not necessarily indicative of actual values
or actual future results that might be achieved, which values may be higher or
lower than those indicated. Moreover, J.P. Morgan's analyses are not and do not
purport to be appraisals or otherwise reflective of the prices at which
businesses actually could be bought or sold.
 
    As a part of its investment banking business, J.P. Morgan and its affiliates
are continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, investments for passive and control
purposes, negotiated underwritings, secondary distributions of listed and
unlisted securities, private placements, and valuations for estate, corporate
and other purposes. J.P. Morgan was selected to deliver an opinion to Sun's
board of directors with respect to the Contour Merger on the basis of such
experience and its familiarity with Sun.
 
    Sun has agreed to reimburse J.P. Morgan for its expenses incurred in
connection with its services, including the fees and disbursements of counsel,
and indemnify J.P. Morgan against certain liabilities, including liabilities
arising under the Federal securities laws. J.P. Morgan will not receive any
additional compensation in connection with the Contour Merger. Sun has also
agreed to pay J.P. Morgan certain fees for services rendered in connection with
the RCA Merger as follows: a $250,000 fee that was paid upon execution of the
engagement letter dated February 6, 1997, as amended April 3, 1998, and agreed
to pay J.P. Morgan a fee of $1,850,000 (including the $250,000 engagement fee)
payable upon consummation of the RCA Merger. See "The RCA Merger--Opinion of
Sun's Financial Advisor."

    J.P. Morgan and its affiliates maintain banking and other business
relationships with Sun and its affiliates, for which it receives customary fees.
In the ordinary course of their businesses, affiliates of J.P. Morgan may
actively trade the debt and equity securities of Sun or Contour for their own
accounts or for the accounts of customers and, accordingly, they may at any time
hold long or short positions in such securities.
 
OPINION OF CONTOUR'S FINANCIAL ADVISOR
 
    Pursuant to an engagement letter dated February 26, 1997, Contour retained
SALI to deliver a fairness opinion in connection with the proposed Contour
Merger.
 
    On April 8, 1997 SALI rendered its written opinion (the "SALI Fairness
Opinion") (the inclusion of which in this Joint Proxy
Statement/Prospectus/Information Statement has been consented to by SALI) to the
board of directors of Contour that, as of April 8, 1997, the consideration to be
paid ("Acquisition Price") by Sun in the proposed Contour Merger was fair from a
financial point of view to the holders of Contour Common Stock. No limitations
were imposed by Contour on the scope of SALI's investigation or the procedures
to be followed by SALI in rendering its opinion.
 
    THE FULL TEXT OF THE SALI FAIRNESS OPINION, WHICH SETS FORTH THE ASSUMPTIONS
MADE, MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS
APPENDIX F TO THIS JOINT PROXY STATEMENT/PROSPECTUS/ INFORMATION STATEMENT AND
IS INCORPORATED HEREIN BY REFERENCE. CONTOUR STOCKHOLDERS ARE URGED TO READ THE
SALI FAIRNESS OPINION FOR A DISCUSSION OF ASSUMPTIONS MADE, PROCEDURES FOLLOWED,
MATTERS CONSIDERED, AND LIMITATIONS ON THIS REVIEW UNDERTAKEN BY SALI IN
RENDERING ITS OPINION. THE SUMMARY OF THE SALI FAIRNESS OPINION SET FORTH IN
THIS JOINT PROXY STATEMENT/PROSPECTUS/INFORMATION STATEMENT IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
    SALI did not advise Contour in the negotiation of the Contour Merger
Agreement and was not retained by Contour until after the Contour Merger
Agreement had been executed. Accordingly, SALI's opinion as to fairness did not
address Contour's underlying decision to proceed with the transaction. The SALI
Fairness Opinion was provided at the request of Contour's board of directors and
does not constitute a recommendation to Contour stockholders concerning whether
or not to vote in favor of the transaction or to take or refrain from taking any
other action in connection with the transaction.
 
    In arriving at its opinion, SALI considered the nature of the business and
history of the enterprise, the economic outlook in general, the outlook for the
healthcare industry and the medical products segment in particular, Contour's
earnings and cash flows for the last four years, the outlook for future
earnings, the book value of the Contour Common Stock, Contour's financial
condition, its dividend-paying capacity, past transactions in Contour Common
Stock, sales of comparable companies, and prices at which other public companies
in related lines of business are selling. SALI had discussions with management
of Contour concerning its financial condition, business, operations, and
prospects and conducted such other analyses as SALI deemed relevant to form a
basis for its opinion.
 
    SALI relied on and assumed the accuracy and completeness of the information
provided by Contour, its employees, attorneys, agents, and representatives,
including any appraisals given to it. SALI did not attempt any independent
verification thereof. SALI did not perform any audit of the information
submitted, including any financial, environmental, or real estate information.
SALI in all cases assumed, but did not verify, the genuineness of all
signatures, the authenticity of all original documents submitted, the conformity
of all copies submitted to the originals, due authorization, execution, and
delivery of all documents and the accuracy of all information supplied and
statements made. SALI assumed that Contour has complied with or will in a timely
fashion comply with all applicable laws, rules, and regulations. SALI further
assumed that Contour has provided all relevant material information concerning
its historical and future business operations and financial condition.

    SALI's opinion is based on economic, industry, market, and other conditions
as in effect on, and the information made available to SALI as of, the date of
such opinion. Subsequent developments may affect SALI's opinion, and SALI does
not have any obligation to update, revise, or reaffirm such opinion. SALI
expressed no opinion as to the price at which the Sun Common Stock will trade at
any future time.
 
    In connection with its analysis and in arriving at its opinion, SALI
performed a variety of financial and comparative analyses, including those
described below.
 
    COMPARABLE TRANSACTION ANALYSIS
 
    With consideration of sales of businesses with some similar characteristics
as Contour, Contour management knows of only one recent transaction that may be
considered comparable. Contour management believes that Gateway Healthcare
Corporation was sold to Gulf South Medical Supply, Inc. in the aggregate for
roughly 60% to 70% of annual sales. In addition, two recent Contour acquisitions
were transacted in the aggregate for roughly 36% and 90% of sales. The
Acquisition Price is roughly 190% of Contour's trailing 12 months' sales. In
addition, it is important to note that minority shares traded in the open market
or in a private transaction typically trade at discounts of 30% or more to
similar transactions where majority shares are considered. SALI's research found
no other comparable sales to have occurred which would allow SALI to use that
valuation as a "yardstick" for Contour.
 
    COMPARABLE COMPANY TRADING MULTIPLE ANALYSIS
 
    Through its research, SALI noted that several publicly traded companies with
market capitalizations similar to that of Contour have significant exposure to
the businesses of manufacturing medical products or the distribution of medical
supplies. This provides some basis for comparison to Contour. These companies
include Conmed Corp., Gulf South Medical Supply, ICU Medical, Isolyser Company,
Maxxim Medical, MBF USA, Medical Action Industries, National Medical, Owens &
Minor, Physician Sales & Service, Rochester Medical, Technol Medical, Urohealth
Systems, and Xomed (collectively, the "Comparable Companies"). It should be
noted that specific exposure to these business lines among the Comparable
Companies is varied in type and significance and that individual circumstances
make each company uniquely different. The Comparable Companies, however, are all
considered small- or micro-cap stocks, and each should be significantly
influenced by the economics of the healthcare industry. SALI believes that
analysis of companies with such a cross section of exposure offers some basis
for comparison with Contour.
 
    SALI's analysis compared key financial and operating ratios among the
Comparable Companies. It compared specific relationships between the Comparable
Companies' stock prices and certain of their financial data and similar
relationships between the Acquisition Price and Contour's financial data. In
this analysis, SALI examined price relationships for each company as of the end
of the month for November and December 1996 and January 1997. In addition, SALI
included the closing price of the Contour Common Stock on February 14, 1997, to
give credit to any market reaction as a result of Contour's announcement of its
earnings for the second quarter of fiscal 1997. SALI chose to analyze market
pricing during the most recent three months as Contour's results include
contributions of two recent acquisitions. SALI believes that these two quarters
most accurately reflect Contour's current operational and financial
characteristics.
 
    When compared to the Comparable Companies, Contour's profit margins are
generally lower, while returns on investment tend to be stronger due to
Contour's use of a generally higher level of financial leverage during the first
half of fiscal 1997. Based on trailing 12 months' earnings, Contour's stock has
recently averaged trading at a 1% premium to the Comparable Companies' mean and
a 21% premium to their median. The Acquisition Price yields a 57% and 88%
premium to the Comparable Companies' mean and median price to trailing 12
months' earnings multiple, respectively. Based on earnings for the most recent
quarter, Contour's stock has recently averaged trading at a 28% discount to the
Comparable Companies' mean and a 7% discount to their median. The Acquisition
Price yields a 12% and 44% premium to the Comparable Companies' mean and median
price-to-trailing-quarter-earnings multiple, respectively.
 
                                      125
<PAGE>
Based on EBITDA (earnings before interest, taxes, depreciation and amortization)
for the most recent quarter, Contour's stock has recently averaged trading at a
23% discount to the Comparable Companies' mean and a 10% premium to their
median. The Acquisition Price yields a 20% and 71% premium to the Comparable
Companies' mean and median price-to-trailing-quarter-EBITDA, respectively. Based
on trailing 12 months' sales, Contour's stock has recently averaged trading at a
54% discount to the Comparable Companies' mean and a 40% discount to their
median. The Acquisition Price yields a 27% and 5% discount to the Comparable
Companies' mean and median price to trailing 12 months' sales multiple,
respectively. Based on book value, Contour's stock has recently averaged trading
at a 7% discount to the Comparable Companies' mean and a 4% premium to their
median. The Acquisition Price yields a 48% and 65% premium to the Comparable
Companies' mean and median price-to-book multiple, respectively. Finally, the
average market capitalization of the Comparable Companies is measured by a mean
of roughly $170 million and a median of roughly $120 million. With one
shareholder owning a majority of Contour and due to a market capitalization of
only $45 million, it is reasonable to expect a significantly thinner trading
volume in Contour stock and thus some market discounting due to less liquidity
of shares.
 
    RECENT TRADING HISTORY
 
    Possibly the strongest indicator of reasonable pricing of Contour Common
Stock based on all available public information and the general trading
liquidity in its stock is the stock's recent trading history. SALI analyzed the
relationships between the price of the Contour Common Stock and Contour's
reported earnings, book value, sales, and EBITDA since the November 5, 1996
reporting of earnings for the first quarter of fiscal 1997. SALI chose Contour's
earnings for the first quarter of fiscal 1997 as its starting point for recent
trading as the financial results of this quarter and the second quarter of
fiscal 1997 both include the contributions of two recent Contour acquisitions.
SALI believes these two quarters most accurately reflect the current operational
and financial characteristics of Contour.
 
    SALI's analysis of recent trading patterns in Contour Common Stock indicates
that the multiple of Acquisition Price to earnings for the second quarter of
fiscal 1997 is a 40% premium to the stock's recent average price-to-earnings
trading history. The multiple of Acquisition Price to Contour's book value as of
December 31, 1996 is a 41% premium to the stock's recent average price-to-book
trading history. The multiple of Acquisition Price to sales for the second
quarter of fiscal 1997 is a 54% premium to the stock's recent average
price-to-sales trading history. The multiple of Acquisition Price to EBITDA for
the second quarter of fiscal 1997 is a 55% premium to the stock's recent average
price-to-EBITDA trading history.
 
    NET REALIZABLE ASSETS
 
    SALI's review of Contour's realizable value of net assets indicates that the
Acquisition Price is at a premium several times that of any possible value to be
realized in a liquidation of its assets. The Acquisition Price is approximately
4.3x Contour's book value per share. Due to the significant premium of the
recent trading patterns in Contour Common Stock to Contour's book value and the
Acquisition Price to Contour's book value, SALI did not believe that Contour's
book value or net asset value was a significant driver of the value of Contour's
Common Stock. Therefore, SALI believed that any differences between Contour's
book value and its net asset value should not have a material impact on the
value of Contour Common Stock.
 
    The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant methods of financial analysis and the
application of those methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. SALI believes
that its analyses must be considered as a whole and that considering any portion
of such analyses and the factors considered, without considering all analyses
and factors, could create a misleading or incomplete view of the process
underlying its opinion. In performing its analyses, SALI made numerous general
assumptions with respect to industry performance, general business and economic
conditions, and other matters, many of which are beyond the control of Sun or
Contour. SALI did not make any specific assumptions with
 
                                      126
<PAGE>
respect to Contour's future financial performance or results of operations, and
was not provided with any internal financial analysis or forecasts prepared by
Sun or Contour. Any estimates contained in these analyses are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than as set forth herein. Any
theoretical or implied values derived from these analyses are not necessarily
indicative of actual fair market values, which may be significantly more or less
favorable than as set forth herein. In addition, analyses relating to the value
of businesses do not purport to reflect the prices at which they may actually be
sold.
 
    For services rendered in connection with and including the delivery of its
opinion on the Contour Merger, Contour has agreed to pay SALI a fee of $100,000.
The fee includes a $25,000 retainer and a $75,000 payment upon the filing of
this Joint Proxy Statement/Prospectus/Information Statement with the Commission.
In addition, Contour has agreed to indemnify SALI against certain liabilities,
including liabilities arising under the Federal securities laws.
 
    SALI is a registered broker/dealer with expertise in retail and
institutional brokerage; investment banking and underwriting; secondary trading
of corporate, municipal, and government securities; and market making in
over-the-counter stocks. The only relationship between SALI and Contour and any
of its affiliates that has existed at any time during the prior two years has
been SALI's preliminary discussions leading to its engagement with respect to
the SALI Fairness Opinion.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion summarizes the material federal income tax
consequences of the Contour Merger to Contour and holders of Contour Capital
Stock. The discussion is based on current law and reflects the opinion of
Shearman & Sterling, special tax counsel to Sun. The discussion does not address
aspects of federal taxation other than income taxation, nor does it address all
aspects of federal income taxation, including, without limitation, aspects of
federal income taxation that may be applicable to particular stockholders, such
as stockholders who are dealers in securities, foreign persons or those who
acquired their Contour Capital Stock in a compensation transaction. The
discussion also does not address the federal income tax consequences of the
Contour Merger to holders of options or warrants to purchase Contour Capital
Stock. In addition, it does not address the state, local or foreign tax
consequences of the Contour Merger, if any.
 
    HOLDERS OF CONTOUR CAPITAL STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS
WITH RESPECT TO THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
CONTOUR MERGER.
 
    Shearman & Sterling will deliver to Sun an opinion to the effect that
assuming that the RCA Merger and Sun's contribution of the Contour Capital Stock
acquired in the Contour Merger to the Surviving RCA Corporation occur promptly
after consummation of the Contour Merger, the Contour Merger would more likely
than not qualify as a tax-free reorganization within the meaning of Section 368
of the Code. In such a case, the material federal income tax consequences of the
Contour Merger to Contour and the holders of Contour Capital Stock will be as
follows: (i) no gain or loss will be recognized by Contour, Sun or RCA in the
Contour Merger; (ii) no gain or loss will be recognized by holders of Contour
Capital Stock upon their receipt of Sun Common Stock in exchange for their
Contour Capital Stock, except that holders of Contour Capital Stock who receive
cash proceeds in lieu of fractional shares of Sun Common Stock will recognize
gain or loss equal to the difference, if any, between such proceeds and the tax
basis of Contour Capital Stock allocated to their fractional share interests;
(iii) such gain or loss, if any, will constitute capital gain or loss if the
fractional share interests exchanged are held as capital assets at the time of
the Contour Merger; (iv) such capital gain or loss will be long-term capital
gain or loss if the holding period for the fractional share interests (including
the holding period of Contour Capital Stock attributed thereto as described
below) exceeds one year; (v) the tax basis of Sun Common Stock received by
holders of Contour Capital Stock will be the same as the tax basis of the
Contour Capital Stock exchanged therefor less the tax
 
                                      127
<PAGE>
basis, if any, allocated to fractional share interests; and (vi) the holding
period of Sun Common Stock in the hands of holders of Contour Capital Stock will
include the holding period of their Contour Capital Stock exchanged therefor;
provided that such Contour Capital Stock is held as a capital asset at the time
of the Contour Merger. On August 5, 1997, legislation was enacted which, among
other things, reduces to 20% the maximum rate of tax on long-term capital gains
on most capital assets held by an individual for more than 18 months, and under
which gain on most capital assets held by an individual more than one year and
up to 18 months is subject to tax at a maximum rate of 28%. The deductibility of
capital losses is subject to limitations. Holders are urged to consult their tax
advisor with respect to the effects of such legislation (and proposed technical
corrections) and the effect of such limitations.
 
    No ruling has been or will be obtained from the Internal Revenue Service
with respect to the Contour Merger. Opinions of counsel are not binding on the
Internal Revenue Service or the courts, and no assurance can be given that the
Internal Revenue Service would not be able to successfully challenge the
conclusions expressed in Shearman & Sterling's tax opinion.
 
    Alternatively, if the RCA Merger and Sun's contribution of the Contour
Capital Stock acquired in the Contour Merger to the Surviving RCA Corporation do
not occur promptly after consummation of the Contour Merger, the Contour Merger
most likely would not qualify as a tax-free reorganization. In such a case, the
material federal income tax consequences of the Contour Merger to the holders of
Contour Capital Stock will be as follows: (i) gain or loss will be recognized by
holders of Contour Capital Stock upon their receipt of Sun Common Stock in
exchange for their Contour Capital Stock; (ii) such gain or loss will equal the
difference between the tax basis in the Contour Capital Stock exchanged and the
fair market value of the Sun Common Stock received; (iii) such gain or loss will
constitute capital gain or loss if the Contour Capital Stock exchanged are held
as capital assets at the time of the Contour Merger; (iv) such capital gain or
loss will be long-term capital gain or loss if the holding period for the
Contour Capital Stock exceeds one year; and (v) the tax basis of the Sun Common
Stock received by holders of Contour Capital Stock will be equal to the fair
market value of the Sun Common Stock on the date of the exchange. As discussed
above, recently enacted legislation may reduce the maximum rate of tax on
long-term capital gains on most capital assets held by an individual. The
deductibility of capital losses is subject to limitations. Holders are urged to
consult their tax advisor with respect to the effects of the legislation (and
proposed technical corrections) and the effect of such limitations. No ruling
has been or will be obtained from the Internal Revenue Service with respect to
the Contour Merger. No assurance can be given that the Internal Revenue Service
would not be able to successfully challenge the characterization of the Contour
Merger as a tax-free reorganization under Section 368 of the Code. The tax
treatment of the Contour Merger to the holders of Contour Capital Stock is
uncertain. HOLDERS OF CONTOUR CAPITAL STOCK ARE STRONGLY URGED TO CONSULT THEIR
OWN TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES OF THE CONTOUR MERGER.
 
    Payments in respect of Contour Capital Stock may be subject to informational
reporting to the Internal Revenue Service and to a 31% back-up withholding tax.
Back-up withholding will not apply, however, to a payment to a holder of Contour
Capital Stock or other payee if such holder or payee completes and signs the
substitute Form W-9 that will be included as part of the transmittal letter or
otherwise proves to Sun and the Contour Exchange Agent that it is exempt from
back-up withholding.
 
LIMITATIONS ON RESALES BY AFFILIATES
 
    All shares of Sun Common Stock received by Contour stockholders in the
Contour Merger will be freely transferable, except that shares of Sun Common
Stock received by persons who are deemed to be "affiliates" of Contour prior to
the Contour Merger may be resold by them only in transactions permitted by the
resale provisions of Rule 145 promulgated under the Securities Act (or Rule 144
in the case of such persons who become affiliates of Sun) or otherwise in
compliance with (or pursuant to an exemption from) the registration requirements
of the Securities Act. Persons deemed to be "affiliates" of Contour or Sun are
those individuals or entities that control, are controlled by, or are under
common control with, such
 
                                      128
<PAGE>
party and generally include executive officers and directors of such party as
well as certain principal stockholders of such party. The Contour Merger
Agreement requires Contour to use its best efforts to cause each of its
affiliates to execute a written agreement to the effect that such person will
not offer or sell or otherwise dispose of any of the shares of Sun Common Stock
issued to such person in or pursuant to the Contour Merger except in compliance
with the Securities Act and the rules and regulations promulgated by the
Commission thereunder. This Joint Proxy Statement/Prospectus/Information
Statement does not cover any resales of Sun Common Stock received by affiliates
of Contour in the Contour Merger. See "The Contour Merger Agreement--Agreements
of Contour Affiliates."
 
ACCOUNTING TREATMENT
 
    If the shareholders of RCA approve the proposed RCA Merger, the acquisition
of the interest in Contour not owned by RCA is expected to be accounted for as a
purchase. If the shareholders of RCA do not approve the proposed RCA Merger, the
acquisition of all of Contour is expected to be accounted for as a purchase.
 
INTERESTS OF CERTAIN PERSONS IN THE CONTOUR MERGER
 
    In considering the recommendation of the Contour board of directors with
respect to the Contour Merger Agreement and the transactions contemplated
thereby, holders of Contour Capital Stock should be aware that certain members
of Contour's management and of the Contour board of directors have interests in
the Contour Merger that are in addition to the interests of Contour's
stockholders in general. These interests arise from, among other things, certain
benefit plans and indemnification arrangements which Sun has agreed to assume
after the Contour Merger.
 
    Not including 5,440,878 shares of Contour Common Stock beneficially held by
RCA as of May 1, 1998, directors and executive officers of Contour beneficially
owned (i) 164,577 shares of Contour Common Stock for which they will receive the
same consideration as other Contour stockholders, (ii) unexercised options to
acquire 344,250 shares of Contour Common Stock, and (iii) fully vested,
unexercised warrants to acquire 52,500 shares of Contour Common Stock at an
exercise price equal to $3.00 per share from June 30, 1999, which will be
treated as described below under "--CONTOUR OPTION GRANTS."
 
    CONTOUR OPTION GRANTS.  As provided in the Contour Merger Agreement, by
virtue of the Contour Merger, each option or warrant granted by Contour to
purchase shares of Contour Common Stock which is outstanding and unexercised
immediately prior to the Contour Effective Time will be assumed by Sun and
converted into an option or warrant to purchase shares of Sun Common Stock in
such number and at such exercise price as is described in the Contour Merger
Agreement. As of May 1, 1998, employees (or former employees) of Contour held
Contour options to purchase an aggregate of 654,250 shares of Contour Common
Stock at a weighted average exercise price of $3.63 per share (at exercise
prices ranging from $1.905 to $5.50 per share). Approval of the Contour Merger
Agreement by the Sun stockholders will constitute stockholder approval of the
assumption by Sun of the rights and obligations of option plans of Contour and
of the amendment of such plans to provide for, among other things, the
conversion at the Contour Effective Time of each outstanding option and warrant
of Contour into an option or warrant to purchase shares of Sun Common Stock. See
"The Contour Merger Agreement--Options and Warrants to Purchase Contour Common
Stock."
 
    INDEMNIFICATION; INDEMNIFICATION AGREEMENTS.  Under the Contour Merger
Agreement, Sun has agreed that the articles of incorporation and bylaws of the
Surviving Contour Corporation in the Contour Merger will contain the
indemnification provisions set forth in Contour's articles of incorporation and
bylaws and that such provisions will not be amended, repealed or otherwise
modified for a period of six years from the Contour Effective Time in any manner
that would adversely affect the rights thereunder of individuals who at the
Contour Effective Time were directors, officers, employees, fiduciaries or
agents of
 
                                      129
<PAGE>
Contour. Sun has also agreed that from and after the Contour Effective Time, Sun
and the Surviving Contour Corporation shall indemnify and hold harmless each
present and former director and officer of Contour against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to matters existing or occurring at
or prior to the Contour Effective Time, whether asserted or claimed prior to, at
or after the Contour Effective Time, to the fullest extent that Contour would
have been permitted under Nevada law and its charter documents (each as in
effect on February 17, 1997) to indemnify such persons.
 
REGULATORY MATTERS
 
    Other than the filing with respect to the RCA Merger, no separate filing is
required under the HSR Act, and no other filing with or approval of any federal
or state governmental entity is required, in connection with the Contour Merger.
 
OPERATIONS FOLLOWING THE CONTOUR MERGER
 
    Following the Contour Merger, Contour will be managed by the same executive
officers and will continue its operations substantially as such operations were
conducted prior to the Contour Merger. Sun and Contour management intend to
cooperate to supply Sun-operated facilities with medical products distributed by
Contour and to integrate Sun's existing medical products manufacturing and
distribution business with Contour's operations. Sun and Contour management
intend to expand the current Contour distribution operations to meet the service
and volume requirements of Sun's long-term care operations and to enable
expansion to nonaffiliated customers.
 
DISSENTERS' RIGHTS
 
    A Contour stockholder who complies with the provisions of Chapter 92A of the
Nevada Revised Statutes ("NRS") has the right to receive a cash payment for his
or her shares of Contour Capital Stock instead of receiving shares of Sun Common
Stock pursuant to the Contour Merger Agreement. The following summary of the
provisions of Chapter 92A is not intended to be a complete statement of such
provisions and is qualified in its entirety by reference to the full text of
Chapter 92A, a copy of which is attached to this Joint Proxy
Statement/Prospectus/Information Statement as Appendix G, and incorporated
herein by reference. Contour stockholders are urged to consult legal counsel
with respect to dissenters' rights.
 
    Stockholders of a Nevada corporation have the right, in certain
circumstances, to dissent from certain corporate actions, including the
consummation of a plan of merger by a Nevada corporation which requires the
approval of such corporation's stockholders. Stockholders who are entitled to
dissent are also entitled to obtain a cash payment in the amount of the fair
value of their shares. The holders of Contour Capital Stock have such rights
with respect to the Contour Merger.
 
    A Contour stockholder who wishes to assert dissenters' rights must (i)
deliver to Contour, before the vote on the Contour Merger is taken, written
notice of his or her intent to demand a cash payment for his or her shares of
Contour Capital Stock if the Contour Merger is effectuated; and (ii) must not
vote his or her shares of Contour Capital Stock in favor of the Contour Merger.
A Contour stockholder failing to satisfy these requirements will not be entitled
to dissenters' rights under Chapter 92A.
 
    Contour must send a written dissenters' notice, as described in NRS 92A.430
(the "Contour Dissenters' Notice"), within ten days of effectuation of the
Contour Merger Agreement, to all Contour stockholders who have satisfied the
above requirements for asserting dissenters' rights. The Contour Dissenters'
Notice must include (i) a statement of where the demand for a cash payment is to
be sent and where and when certificates, if any, for Contour Capital Stock are
to be deposited; (ii) a statement informing the holders of Contour Capital Stock
not represented by certificates to what extent the transfer of such shares
 
                                      130
<PAGE>
will be restricted after the demand for a cash payment is received; (iii) a form
for demanding a cash payment that includes the date of the first announcement to
the news media or to the stockholders of the terms of the proposed action (the
"Announcement Date"), which form requires the Contour stockholder asserting the
dissenters' rights to certify whether or not such stockholder acquired
beneficial ownership of the shares of Contour Capital Stock before the
Announcement Date; (iv) a date by which Sun must receive the demand for a cash
payment, which may not be less than 30 or more than 60 days after the date the
Contour Dissenters' Notice was delivered; and (v) a copy of NRS Sections 92A.300
to 92A.500.
 
    A Contour stockholder who wishes to obtain a cash payment for his or her
shares of Contour Capital Stock must demand payment, certify whether he or she
acquired beneficial ownership of his or her shares of Contour Capital Stock
before the Announcement Date, and deposit his or her certificates, if any, in
accordance with the terms of the Contour Dissenters' Notice. A Contour
stockholder for whom dissenters' rights are asserted as to shares not
represented by a certificate will retain all other rights of a Contour
stockholder until those rights are canceled or modified by the Contour Merger.
Contour may restrict the transfer of any shares not represented by a certificate
from the date the demand for a cash payment is received. Pursuant to NRS Section
92A.440, a Contour stockholder who fails to demand a cash payment or deposit his
or her certificates where required by the dates set forth in the Contour
Dissenters' Notice will not be entitled to a cash payment for his or her shares
as provided under Chapter 92A.
 
    Pursuant to NRS Section 92A.460, within 30 days of receipt of a demand for a
cash payment, Contour must pay each dissenter who complied with NRS Section
92A.440 the amount of cash that Contour estimates to be the fair market value of
his or her shares of Contour Capital Stock, plus accrued interest. This cash
payment obligation may be enforced by the district court of the county where the
corporation's registered office is located or, at the election of any dissenter
residing or having its registered office in Nevada, of the county where the
dissenter resides or has its registered office. The court is required to dispose
of the action promptly. The cash payment must be accompanied by (i) certain
financial information regarding Contour; (ii) a statement of Contour's estimate
of the fair value of the shares; (iii) an explanation of how the interest was
calculated; (iv) a statement of the dissenters' rights to demand a cash payment
under NRS Section 92A.480; and (v) a copy of NRS Sections 92A.300 to 92A.500.
 
    Pursuant to NRS Section 92A.470, Contour may elect to withhold payment from
dissenters who became the beneficial owners of their shares on or after the
Announcement Date. After consummation of the Contour Merger, however, Contour
must estimate the fair value of such shares of Contour Capital Stock, plus
accrued interest, and offer to pay this amount in cash to each dissenter who
agrees to accept it in full satisfaction of his or her demand. Contour will send
this offer with a statement of its estimate of the fair value of the shares, an
explanation of how the interest was calculated and a statement of the
dissenters' rights to demand a cash payment under NRS Section 92A.480.
 
    Pursuant to NRS Section 92A.480, a dissenter who believes that the amount
paid pursuant to NRS Section 92A.460 or offered pursuant to NRS Section 92A.470
is less than the fair value of his or her shares of Contour Capital Stock or
that the interest due is incorrectly calculated may, within 30 days after
Contour made or offered a cash payment for his or her shares of Contour Capital
Stock, either (i) notify Contour in writing of his or her own estimate of the
fair value of such shares and the amount of interest due and demand a cash
payment of such estimate less any payments made under NRS Section 92A.460, or
(ii) reject the offer for a cash payment made by Contour under NRS Section
92A.470 and demand a cash payment of the fair value of his or her shares and
interest due.
 
    If a demand for a cash payment remains unsettled, Contour must commence a
court proceeding within 60 days after receiving a demand and petition the court
to determine the fair value of the shares and accrued interest. All dissenters
whose demands remain unsettled would be made a party to such a proceeding. Each
dissenter is entitled to a judgment for the fair value of his or her shares of
Contour Capital Stock, plus accrued interest, less any amount paid pursuant to
NRS Section 92A.460. The court will assess the costs of the proceedings against
Contour unless the court finds that all or some of the dissenters
 
                                      131
<PAGE>
acted arbitrarily, vexatiously or not in good faith in demanding a cash payment,
in which case the court may assess the costs in the amount the court finds
equitable against some or all of the dissenters. The court may also assess the
fees and expenses of the counsel and experts for the respective parties, in the
amount the court finds equitable, against Contour or the dissenters. If Contour
does not commence a proceeding within the 60-day period, it must pay each
dissenter whose demand remains unsettled the amount of cash demanded.
 
CONTOUR CONVERTIBLE DEBENTURES
 
    Contour has outstanding $5,000,000 aggregate principal amount of 9.00%
Convertible Debentures (the "Contour Debentures"), which are convertible into
shares of Contour Common Stock at a conversion price of $5.00 per share, subject
to adjustment in certain circumstances. Under the terms of the indenture
governing the Contour Debentures, in the event the Contour Common Stock is not
listed on The Nasdaq National Market, the NYSE, the American Stock Exchange or
The Nasdaq Small-Cap Market, the Contour Debentures shall be redeemed at the
greater of (i) the market value of the Contour Debentures and (ii) 123% of par
until July 12, 1998 (and progressively higher amounts thereafter). The Contour
Debentures and the loan agreement pursuant to which the Contour Debentures were
issued contain default and other provisions contained in loan agreements
generally and grant the holders of the Contour Debentures the right to name one
director to Contour's board of directors.
 
    On December 31, 1997, Sun purchased all of the Contour Debentures from
Renaissance Capital Growth and Income Fund II, Inc. and Renaissance U.S. Growth
and Income Trust, PLC (collectively, "Renaissance") in a privately negotiated
transaction for an aggregate purchase price of $8.4 million in cash. Renaissance
had not exercised, and Sun does not expect to exercise, its right to name a
director to Contour's Board of Directors. As of June 30, 1997, September 30,
1997 and December 31, 1997, Contour was not in compliance with certain financial
ratios required to be maintained under the Contour Debenture. On April 2, 1998,
Sun agreed to waive such default until 10 business days after the termination of
the Contour Merger Agreement.
 
EXCHANGE OF SHARES
 
    At or prior to the Contour Effective Time, Sun will appoint, and will retain
for a period of at least six months after the Contour Effective Time, an
exchange agent (the "Contour Exchange Agent") to effect the exchange of shares
of Contour Capital Stock for Sun Common Stock, in connection with the Contour
Merger. From time to time after the Contour Effective Time, Sun shall deposit,
or cause to be deposited, certificates representing Sun Common Stock for
conversion of shares of Contour Capital Stock in accordance with the Contour
Merger Agreement.
 
    Commencing immediately after the Contour Effective Time and until the
appointment of the Contour Exchange Agent is terminated, each holder of a
certificate or certificates theretofore evidencing shares of Contour Capital
Stock may surrender the same, to the Contour Exchange Agent, and, after the
appointment of the Contour Exchange Agent has been terminated, any such holder
may surrender any such certificate to Sun. Such holder will be entitled upon
such surrender to receive in exchange therefor a certificate or certificates
representing the number of full shares of Sun Common Stock into which the shares
of Contour Capital Stock theretofore represented by the certificate or
certificates so surrendered have been converted pursuant to the Contour Merger,
together with a cash payment in lieu of fractional shares, if any, and all such
shares of Sun Common Stock will be deemed to have been issued at the Contour
Effective Time. Until surrendered and exchanged, each outstanding certificate
which, prior to the Contour Effective Time, represented issued and outstanding
shares of Contour Capital Stock will be deemed for all corporate purposes of
Sun, other than the payment of dividends and other distributions, if any, to
evidence ownership of the number of full shares of Sun Common Stock into which
the shares of Contour Capital Stock theretofore represented thereby have been
converted at the Contour Effective Time.
 
                                      132
<PAGE>
    Until certificates representing shares of Contour Capital Stock are
surrendered, no dividend or other distribution, if any, payable to the holders
of record of Sun Common Stock as of any date subsequent to the Contour Effective
Time will be paid to the holder of such certificate. Upon the surrender of any
such certificate representing shares of Contour Capital Stock, however, the
record holder of the certificate or certificates representing shares of Sun
Common Stock issued in exchange therefor will receive from the Contour Exchange
Agent or from Sun, as the case may be, payment of the amount of dividends and
other distributions, if any, which as of any date subsequent to the Contour
Effective Time and until such surrender will have become payable with respect to
such number of shares of Sun Common Stock. No interest will be payable with
respect to the payment of any such presurrender dividends upon the surrender of
certificates theretofore representing shares of Contour Capital Stock.
 
    No fractional share certificates for Sun Common Stock will be issued upon
the surrender for exchange of certificates evidencing shares of Contour Capital
Stock. In lieu thereof, the Contour Exchange Agent or Sun, as the case may be,
will pay each holder of Contour Capital Stock an amount in cash calculated as
provided in the Contour Merger Agreement.
 
    Risk of loss and title to certificates representing shares of Contour
Capital Stock will pass only upon proper delivery of such certificates to the
Contour Exchange Agent.
 
    At the Contour Effective Time, the stock transfer books of Contour with
respect to shares of Contour Capital Stock will each be closed, and there will
be no further registration of transfers of shares of Contour Capital Stock
thereafter on the records of any such stock transfer books. In the event of a
transfer of ownership of shares of Contour Capital Stock that is not registered
in the stock transfer records of Contour, at the Contour Effective Time, a
certificate or certificates representing the number of full shares of Sun Common
Stock into which such shares of Contour Capital Stock have been converted will
be issued to the transferee together with a cash payment in lieu of fractional
shares, if any, and a cash payment in the amount of any presurrender dividends,
if any, if the certificate or certificates representing such shares of Contour
Capital Stock is or are properly surrendered as described above, accompanied by
all documents required to evidence and effect such transfer and by evidence of
payment of any applicable stock transfer tax.

                          THE CONTOUR MERGER AGREEMENT
 
    The description of the Contour Merger Agreement contained in this Joint
Proxy Statement/Prospectus/Information Statement is qualified in its entirety by
reference to the complete text of the Contour Merger Agreement, as amended by
Amendment No. 1 thereto dated as of August 21, 1997, Amendment No. 2 thereto
dated as of November 25, 1997 and Amendment No. 3 thereto dated as of April 3,
1998, copies of which are attached hereto as Appendices D, D-1, D-2 and D-3,
respectively, and are incorporated herein by reference.
 
CONTOUR EFFECTIVE TIME
 
    The Contour Merger will become effective by the filing of a certificate of
merger (the "Contour Certificate of Merger") with the Secretary of State of the
State of Nevada. However, there can be no assurance that the conditions to the
Contour Merger will be satisfied or that the Contour Merger Agreement will not
be terminated.
 
CORPORATE MATTERS
 
    At the Contour Effective Time the articles of incorporation and by-laws of
Contour Merger Sub, as in effect immediately prior to the Contour Effective
Time, will become the articles of incorporation and by-laws of the Surviving
Contour Corporation, and the officers and directors of Contour Merger Sub
immediately prior to the Contour Effective Time will become the initial officers
and directors of the Surviving Contour Corporation.
 
CONVERSION OF SECURITIES
 
    At the Contour Effective Time, by virtue of the Contour Merger and without
any action on the part of Sun, Contour Merger Sub, Contour, the holders of
Contour Capital Stock or the holders of common stock, par value $.001 per share,
of Contour Merger Sub, (i) each share of Contour Capital Stock issued and
outstanding immediately prior to the Contour Effective Time, other than shares
owned by RCA, will be converted into shares of Sun Common Stock as described
above under "The Contour Merger--Conversion of Contour Capital Stock," (ii) each
outstanding share of Contour Capital Stock owned by RCA will not be exchanged in
the Contour Merger and will remain outstanding (other than in the circumstances
described below) and (iii) each share of common stock, par value $.001 per
share, of Contour Merger Sub issued and outstanding immediately prior to the
Contour Effective Time and all rights in respect thereof will forthwith cease to
exist and will be converted into and become exchangeable for one newly and
validly issued, fully paid and nonassessable share of common stock of the
Surviving Contour Corporation. Notwithstanding the foregoing, if the RCA Merger
does not occur promptly after consummation of the Contour Merger, or if Sun does
not undertake to contribute to RCA all shares of Contour Capital Stock obtained
by Sun pursuant to the Contour Merger, RCA would receive the same per share
consideration as the other holders of Contour Capital Stock pursuant to clause
(i) above.
 
OPTIONS AND WARRANTS TO PURCHASE CONTOUR COMMON STOCK
 
    At the Contour Effective Time, each option or warrant granted by Contour to
purchase shares of Contour Common Stock which is outstanding and unexercised
immediately prior to the Contour Effective Time, will be assumed by Sun and
converted into an option or warrant to purchase shares of Sun Common Stock in
such number and at such exercise price as described below and otherwise having
the same terms and conditions as in effect immediately prior to the Contour
Effective Time (except to the extent that such terms, conditions and
restrictions may be altered in accordance with their terms as a result of the
Contour Merger). The number of shares of Sun Common Stock to be subject to the
new option or warrant will be equal to the product of (i) the number of shares
of Contour Common Stock subject to the original option or warrant multiplied by
(ii) the Contour Common Exchange Ratio. The exercise price per share of Sun
 
                                      134
<PAGE>
Common Stock under the new option or warrant will be equal to the quotient of
(i) the exercise price per share of Contour Common Stock under the original
option or warrant divided by (ii) the Contour Common Exchange Ratio. Upon each
exercise of options or warrants by a holder thereof, the aggregate number of
shares of Sun Common Stock deliverable upon such exercise will be rounded down,
if necessary, to the nearest whole share and the aggregate exercise price will
be rounded up, if necessary, to the nearest cent.

material assets.
 
NOTICES OF CERTAIN EVENTS
 
    The Contour Merger Agreement provides that each of Sun and Contour must give
prompt notice to the other of (i) any notice or other communication from any
person alleging that the consent of such person is or may be required in
connection with the Contour Merger; (ii) any notice or other communication from
any governmental entity in connection with the Contour Merger; (iii) any
actions, suits, claims, investigations or proceedings commenced or, to its
knowledge, threatened against, relating to or involving or otherwise affecting

Sun to perform its obligations pursuant to the Contour Merger Agreement and to
effect the consummation of the Contour Merger.
 
ACCESS TO INFORMATION; CONFIDENTIALITY
 
    The Contour Merger Agreement provides that, from the date of the Contour
Merger Agreement to the Contour Effective Time, each of Sun and Contour must (i)
provide to the other access at reasonable times to its officers, employees,
agents, properties, offices and other facilities and to the books and records
thereof and (ii) furnish promptly such information concerning its and its
subsidiaries' business, properties, contracts, assets, liabilities and personnel
as the other party may reasonably request. In addition, the obligations of Sun
and Contour under the confidentiality agreements entered into between Sun and
RCA as of November 12, 1996 and December 20, 1996 remain in effect.
 
NO SOLICITATION OF TRANSACTIONS
 
    Pursuant to the Contour Merger Agreement, Contour may not, directly or
indirectly, solicit, initiate or knowingly encourage (including by way of
furnishing nonpublic information), or take any other action knowingly to
facilitate, any inquiries or the making of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders) that constitutes,
or may reasonably be expected to lead to, any
 
                                      136
<PAGE>
Competing Transaction (as defined below), or enter into or maintain or continue
discussions or negotiate with any person in furtherance of such inquiries or to
obtain a Competing Transaction, or agree to or endorse any Competing
Transaction, or authorize or permit any of Contour's officers, directors or
employees, or any investment banker, financial advisor, attorney, accountant or
other representative retained by Contour, to take any such action. However, the
Contour Merger Agreement provides that the board of directors of Contour may (i)
comply with Rule 14e-2 promulgated under the Exchange Act with regard to a
tender or exchange offer and (ii) after receiving the advice of outside counsel
to the effect that Contour's board of directors is required to do so in order to
discharge properly its fiduciary duties, consider, negotiate, approve and
recommend to its stockholders an unsolicited BONA FIDE written acquisition
proposal which (A) was not received in violation of the Contour Merger
Agreement, (B) if executed or consummated would be a Competing Transaction, (C)
is not subject to financing and (D) Contour's board of directors determines in
good faith, after the receipt of an opinion of its financial advisor, would
result in a transaction more favorable to Contour's stockholders than the
Contour Merger (any such acquisition proposal, a "Superior Proposal"). The
Contour Merger Agreement requires that Contour must notify Sun and Contour
Merger Sub promptly if any proposal or offer, or any inquiry or contact with any
person with respect thereto, regarding such an acquisition proposal or a
Competing Transaction is made.
 
    For purposes of the Contour Merger Agreement, "Competing Transaction" means,
with respect to Contour, (i) any merger, consolidation, share exchange, business
combination or other similar transaction; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of 15 percent or more of the
assets of Contour, in a single transaction or series of transactions; (iii) any
tender offer or exchange offer for 25 percent or more of the outstanding voting
securities of Contour or the filing of a registration statement under the
Securities Act in connection therewith; (iv) any person having acquired
beneficial ownership or the right to acquire beneficial ownership of, or any
"group" (as such term is defined under Section 13(d) of the Exchange Act) having
been formed which beneficially owns or has the right to acquire beneficial
ownership of, 25 percent or more of the outstanding voting securities of
Contour; (v) any solicitation in opposition to the approval of the Contour
Merger Agreement by the stockholders of Contour; or (vi) any public announcement
of a proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing.
 
FURTHER ACTION; CONSENTS; FILINGS
 
    The Contour Merger Agreement provides that each of Contour and Sun must use
all reasonable efforts to (i) take, or cause to be taken, all appropriate
action, and do, or cause to be done, all things necessary, proper or advisable
under applicable law or otherwise to consummate and make effective the Contour
Merger, (ii) obtain from governmental entities any consents, licenses, permits,
waivers, approvals, authorizations or orders required to be obtained or made by
Sun, Contour Merger Sub, Contour or the Surviving Contour Corporation in
connection with the authorization, execution and delivery of the Contour Merger
Agreement and the consummation of the Contour Merger and (iii) make all
necessary filings, and thereafter make any other required or appropriate
submissions, with respect to the Contour Merger Agreement and the Contour Merger
required under the rules and regulations of the NYSE, the Securities Act, the
Exchange Act and any other applicable federal or state securities laws and any
other applicable law. Contour and Sun are also required to promptly give any
notices regarding the Contour Merger, the Contour Merger Agreement or the
transactions contemplated thereby to third parties required under applicable law
or by any contract, license, lease or other agreement to which it is bound, and
to use all reasonable efforts to obtain any third party consents required under
any such contract, license, lease or other agreement in connection with the
consummation of the Contour Merger or the other transactions contemplated by the
Contour Merger Agreement.
 
                                      137
<PAGE>
NYSE LISTING
 
    Contour and Sun have each agreed to use all reasonable efforts to obtain,
prior to the Contour Effective Time, the approval for listing on the NYSE,
effective upon official notice of issuance, of the shares of Sun Common Stock
into which the shares of Contour Capital Stock will be converted pursuant to the
Contour Merger.
 
AGREEMENTS OF CONTOUR AFFILIATES
 
    Rule 145 promulgated under the Securities Act regulates the disposition of
securities of "affiliates" of Contour in connection with the Contour Merger.
Contour has delivered to Sun a letter (the "Affiliate Letter") identifying each
person who was, in Contour's reasonable judgment, at the Contour Record Date, an
"affiliate" of Contour for purposes of Rule 145 under the Securities Act.
Contour has also agreed to use all reasonable efforts to cause each person (an
"Affiliate") who is identified as an Affiliate in the Affiliate Letter to
deliver to Sun, prior to the Contour Effective Time, a written agreement (an
"Affiliate Agreement"). Under such Affiliate Agreements, every Affiliate will
represent that he or she has been advised that the Affiliate may not sell,
transfer or otherwise dispose of Sun Common Stock issued to the Affiliate in the
RCA Merger unless such sale, transfer or other disposition (i) has been
registered under the Securities Act, (ii) is made in compliance with the
requirements of Rule 145 under the Securities Act, or (iii) in the opinion of
counsel reasonably acceptable to Sun, is otherwise exempt from registration
under the Securities Act.
 
    In addition, all executive officers and directors of Contour have confirmed
that they intend to vote their respective shares of Contour Capital Stock in
favor of the Contour Merger.
 
DIRECTORS' AND OFFICERS' INDEMNIFICATION
 
    Under the Contour Merger Agreement, Sun has agreed that the articles of
incorporation of the Surviving Contour Corporation in the Contour Merger will
contain the indemnification provisions set forth in Contour's articles of
incorporation and that such provisions will not be amended, repealed or
otherwise modified for a period of six years from the Contour Effective Time in
any manner that would adversely affect the rights thereunder of individuals who
at the Contour Effective Time were directors, officers, employees, fiduciaries
or agents of Contour. Sun has also agreed that from and after the Contour
Effective Time, Sun and the Surviving Contour Corporation shall indemnify and
hold harmless each present and former director and officer of Contour against
any costs or expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages or liabilities incurred in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of or pertaining to matters
existing or occurring at or prior to the Contour Effective Time, whether
asserted or claimed prior to, at or after the Contour Effective Time, to the
fullest extent that Contour would have been permitted under Nevada law and its
charter documents (each as in effect on February 17, 1997) to indemnify such
persons.

            THE CONTOUR STOCKHOLDER STOCK OPTION AND PROXY AGREEMENT
 
    Concurrent with the execution of the Contour Merger Agreement and as a
condition to the willingness of Sun to enter into the Contour Merger Agreement,
Sun entered into a Stockholder Stock Option and Proxy Agreement, dated as of
February 17, 1997, as amended by Amendment No. 1 thereto dated as of November
25, 1997 (as amended, the "Contour Stock Option Agreement"), with RCA, which
owned as of such date approximately 65% of the outstanding shares of Contour
Capital Stock. Pursuant to the Contour Stock Option Agreement, RCA (i) granted
to Sun an irrevocable option to purchase RCA's shares of Contour Capital Stock
at a price equal to $8.50 per share, and $4.00 per share of Contour Preferred
Stock, under certain circumstances, and (ii) agreed to vote, and granted to Sun
an irrevocable proxy to vote, all voting securities of Contour held by RCA in
favor of approval of the Contour Merger Agreement and the Contour Merger.
 
    The following description of the Contour Stock Option Agreement is qualified
in its entirety by reference to the complete text of the Contour Stock Option
Agreement, a copy of which is attached as Exhibit 1.00(a) to the Contour Merger
Agreement attached hereto as Appendix D and incorporated herein by reference.
 
    Pursuant to the Contour Stock Option Agreement, RCA granted to Sun an option
(the "Contour Stock Option") to purchase RCA's Contour Capital Stock (the
"Contour Option Shares"), representing approximately 65% of the shares of
Contour Common Stock issued and outstanding on the date of grant, at a purchase
price of $8.50 per share of Contour Common Stock and $4.00 per share of Contour
Preferred Stock (the "Contour Option Purchase Price").
 
    Sun may exercise the Contour Stock Option, in whole or in part, at any time
following the earlier of (i) the termination of the Contour Merger Agreement
other than a termination due to a final and nonappealable judgment preventing
the Contour Merger, and (ii) the first occurrence of a Competing Transaction,
until the expiration of the Contour Stock Option.
 
    The Contour Stock Option Agreement provides that, in the event Sun wishes to
exercise the Contour Stock Option, it must send a written notice to RCA
specifying the place and date, not later than ten business days and not earlier
than three business days following the date of such notice, for closing such
purchase. If Sun exercises the Contour Stock Option, RCA must execute and
deliver further transfers, assignments, endorsements, consents and other
instruments as Sun may reasonably request for the purpose of effectively
carrying out the option. At the closing, Sun must pay the aggregate Contour
Option Purchase Price for the shares of Contour Capital Stock being purchased
from RCA by wire transfer in immediately available funds of the total amount of
the Contour Option Purchase Price or by delivery of a number of shares of Sun
Common Stock equal to the quotient of the total amount of the Contour Option
Purchase Price and the average of the last reported sales prices of one share of
Sun Common Stock on the NYSE during the period of the 20 most recent trading
days, or cash, as the case may be. RCA must deliver to Sun a certificate or
certificates evidencing RCA's shares of Contour Capital Stock, free and clear of
any liens, and, in the event that Sun has elected to pay the Contour Option
Purchase Price in shares of Sun Common Stock, RCA will receive a certificate or
certificates evidencing the Sun Common Stock shares to be received by RCA at
closing.
 
    The Contour Stock Option Agreement provides that, during the term of the
Contour Stock Option, RCA shall not (i) sell, pledge or otherwise dispose of any
of its shares of Contour Capital Stock, (ii) deposit its shares of Contour
Capital Stock into a voting trust or enter into a voting agreement with respect
to such shares, or (iii) enter into any contract, option or other arrangement or
undertaking with respect to the direct or indirect acquisition or sale,
assignment, transfer or other disposition of any Contour Capital Stock.
 
    The Contour Stock Option Agreement further provides that RCA, with respect
to those shares of Contour Capital Stock that it owns of record, appoint Sun, or
any nominee of Sun, during the term of the
 
                                      141
<PAGE>
Contour Stock Option, as its true and lawful proxy, to vote all of the shares of
Contour Capital Stock held by RCA at every annual, special or adjourned meeting
of the stockholders of Contour (i) in favor of the adoption of the Contour
Merger Agreement and approval of the Contour Merger and any other transactions
contemplated by the Contour Merger Agreement, (ii) against any proposal for any
recapitalization, merger, sale of assets or other business combination between
Contour and any other person or entity (other than the Contour Merger) or any
other action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of Contour under
the Contour Merger Agreement or which could result in any of the conditions to
Contour's obligations under the Contour Merger Agreement not being fulfilled,
and (iii) in favor of any other matter relating to consummation of the
transactions contemplated by the Contour Merger Agreement. RCA further agreed to
cause the shares of RCA Capital Stock owned by it beneficially to be voted in
accordance with the RCA Stockholders' Stock Option and Proxy Agreement.
 
    The Contour Stock Option Agreement also provides that Sun shall, within
three months following the closing, file with the Commission a shelf
registration statement relating to the resale of the shares of Sun Common Stock
issuable upon exercise of a Contour Stock Option by the Stockholders from time
to time in accordance with the methods of distribution set forth in such shelf
registration statement, and shall use its best efforts to cause such shelf
registration statement to be declared effective under the Securities Act as soon
as practicable thereafter. Sun is also required to use its best efforts to keep
the shelf registration statement continuously effective for up to two years
following the closing.
 
    The Contour Stock Option Agreement will expire by its terms (i) if the
Contour Stock Option is not exercised prior to the close of business on the 14th
day following termination of the Contour Merger Agreement, (ii) if the Contour
Merger Agreement is terminated due to entry of a final and nonappealable
judgment preventing consummation of the Contour Merger or (iii) if the Contour
Merger Agreement is terminated or terminable due to Sun's uncured breach of any
representation, warranty, covenant or agreement.

                                      SUN
 
    Sun is a leading provider of high-quality and cost-efficient long-term,
subacute and related specialty healthcare services in the United States and the
United Kingdom, and also has operations in Spain, Germany and Australia. At
March 31, 1998, Sun operated 318 long-term and subacute care facilities (which
includes assisted living and managed facilities) with 36,488 licensed beds in
the United States, and 177 long-term and acute care facilities with 11,132
licensed beds internationally. Sun is one of the largest providers of ancillary
services to long-term care providers in the United States, including provision
of rehabilitation therapy (the provision of physical, occupational and speech
therapy), respiratory therapy (the provision of respiratory therapy and the
distribution of related equipment and supplies), temporary therapy staffing
services, and pharmaceutical products and services. Sun provides these services
to over 1,500 affiliated and nonaffiliated long-term and subacute care
facilities in the United States. After giving pro forma effect to the Regency
Acquisition, which closed in the fourth quarter of 1997, Sun's revenues for the
year ended December 31, 1997 would have been approximately $2.5 billion.
 
    Sun's inpatient care facilities provide a broad range of healthcare
services, including nursing care, subacute care, therapy and other specialized
services such as care to patients with Alzheimer's disease. Sun's long-term and
subacute care operations have experienced significant growth since Sun's
inception in 1989, primarily from acquisition of additional facilities. Sun
believes its inpatient care operations provide it with a platform to expand its
therapy and pharmaceutical businesses (which include dispensing pharmaceuticals
for such purposes as infusion therapy, pain management, antibiotic therapy and
parenteral nutrition) to affiliated and nonaffiliated long-term and subacute
care facilities. Sun believes that its expertise in operating long-term and
subacute care facilities enables it to provide its therapy and pharmaceutical
services more effectively and efficiently than providers without such operating
expertise.
 
    Through CareerStaff, Sun is a nationwide provider of temporary therapy
staffing. CareerStaff provides licensed therapists skilled in the areas of
physical, occupational and speech therapy primarily to hospitals and nursing
home contract service providers. At March 31, 1998, Sun had 29 division offices
providing temporary therapy staffing services in major metropolitan areas and
four division offices specializing in placements of temporary traveling
therapists in smaller cities and rural areas.
 
    Through SunScript, as of March 31, 1998, Sun operated 42 pharmacies and one
pharmaceutical billing and consulting center which together provided
pharmaceutical products and services to a total of 840 long-term and subacute
care facilities in 27 states, 576 of which were nonaffiliated. In addition, Sun
operates 19 pharmacies and one supply distribution center in the United Kingdom
at March 31, 1998.
 
    In October 1997, Sun acquired Regency, an operator of skilled nursing
facilities and a diversified provider of rehabilitation therapy, institutional
pharmacy and home health services, for approximately $575 million, including
approximately $345 million in cash ($22.00 per Regency share) and the assumption
or refinancing of approximately $230 million of Regency's indebtedness. See
"Unaudited Pro Forma Combined Financial Statements." Pursuant to the Regency
Acquisition, Sun acquired 110 long-term care facilities with 11,440 beds, 26
outpatient rehabilitation therapy clinics and eight institutional pharmacies.
 
    In 1997, Sun expanded its international operations by acquiring 83
facilities in the United Kingdom, Spain, Australia and Germany. Sun operates 152
facilities with 8,517 licensed beds as of March 31, 1998. Sun's growth in the
United Kingdom is due in large part to its acquisitions of APTA in December 1996
and Ashbourne in January 1997, which together added 81 long-term care facilities
with 4,877 licensed beds to Sun's operations.
 
    In July 1997, Sun acquired a majority interest in Eurosar, a privately owned
operator of eight long-term care facilities in Spain with 1,328 licensed beds.
In August 1997, Sun acquired 38% of the equity of Alpha, a publicly held acute
care provider in Australia that operated ten facilities with 686 licensed beds.
In November 1997, Sun acquired from Moran a majority interest in six hospitals
in Australia. In December
 
                                      143
<PAGE>
1997, Sun acquired a majority interest in Heim Plan--Uternehmensgruppe, an
operator of 11 long-term facilities with 930 licensed beds in Germany.
 
    After giving effect to the Regency Acquisition and assuming the RCA Merger
and Contour Merger are each consummated, Sun would have operated on a PRO FORMA
basis 605 facilities with 58,992 beds in 28 states in the United States and in
the United Kingdom, Spain, Germany and Australia as of March 31, 1998. However,
no assurance can be given as to whether either of the Mergers will be
consummated.
 
    The principal executive offices of Sun are located at 101 Sun Avenue, N.E.,
Albuquerque, New Mexico 87109, and its telephone number at that location is
(505) 821-3355.
 
    Additional information concerning Sun is included in documents previously
filed by Sun with the Commission and which are incorporated by reference in this
Joint Proxy Statement/Prospectus/Information Statement. See "Available
Information" and "Incorporation of Certain Documents by Reference."
 
RECENT DEVELOPMENTS CONCERNING SUN
 
    On May 4, 1998, Sun completed the Debt Offering consisting of a private
placment of $125.0 million ($150.0 million if the over-allotment option is
exhausted in full) aggregate principal amount of its 9 5/8% Senior Subordinated
Notes due 2008, (having an aggregate liquidiation amount of $345.0 million).
Concurrently with the Debt Offering, Sun and Sun Financing I, a statutory
business trust formed under the Convertible Securities Offering consisting of a
of the State of Delaware and a wholly-owned subsidiary of Sun, completed
separate private placement of 13,800,000 shares of its 7% Convertible Trust
Issued Preferred Securities (liquidation amount $25 per share) having an
aggregate liquidation amount of $345.0 million, the proceeds of which were
loaned to Sun. A portion of the net proceeds from the Convertible Securities
Offering were used to repay approximately $300.0 million of outstanding
borrowings under the term loan portion of the Credit Facility. The remaining net
proceeds from the Offerings were used to reduce outstanding borrowings under the
revolving credit portion of the Credit Facility, which amount may be
subsequently reborrowed.
 
    On or about January 23, 1996, two former stockholders of SunCare, John
Brennan and Susan Bird, filed a lawsuit (the "SunCare Litigation") against Sun
and certain of its officers and directors in the United States District Court
for the Southern District of Indiana. Plaintiffs allege, among other things,
that Sun did not disclose material facts concerning the investigation by the OIG
and that Sun's financial results were misstated. The complaints purport to state
claims, INTER ALIA, under Federal and state securities laws and for breach of
contract, including a breach of a registration rights agreement pursuant to
which Sun agreed to register the shares of Sun's common stock issued to such
former stockholders of SunCare in the acquisition. On May 21, 1998, Sun and the
plaintiffs reached an agreement in principle to settle the action for $7.4
million. The settlement is subject to the execution of definitive documentation.
The settlement of $7.4 million will be recorded by Sun as a pretax charge during
the second quarter of 1998.

                                      RCA
 
    RCA is a leading provider in the southeastern United States of senior
residential care services, which include long-term care, assisted living and
independent living services. As of December 31, 1997, RCA's 74 owned, leased or
managed long-term care facilities provided skilled nursing care, specialty care
services and ancillary services to patients, while its 36 owned, leased or
managed, assisted/independent living centers provided services to residents in
need of varying degrees of assistance with the activities of daily living. RCA's
facilities are located primarily in rural and non-urban areas in the
southeastern United States, and it is the largest provider of senior residential
care services in Georgia.
 
    LONG-TERM CARE SERVICES.  Basic resident services are those traditionally
provided to elderly patients in long-term care facilities with respect to daily
living activities and general medical needs. RCA provides in all of its
facilities room and board, 24-hour skilled nursing care by registered nurses,
licensed practical nurses and certified nursing aides, and a broad range of
support services, including dietary services, therapeutic recreational
activities, social services, housekeeping and laundry services, pharmaceutical
and medical supplies, physical, speech, occupational and respiratory therapy,
wound care and other ancillary services.
 
    ASSISTED LIVING SERVICES.  RCA's assisted living centers are designed to
assist those persons generally 75 years of age or over who may require
assistance with any of the five basic activities of daily life (I.E., bathing,
dressing, eating, walking and toileting). RCA's assisted living centers offer
residents private or semi-private accommodations, ongoing health assessments,
three meals per day and snacks approved by a registered dietician, as well as
24-hour assistance with activities of daily life, housekeeping service, linen
and personal laundry service, organized social activities and transportation.
The assisted living services are provided in free-standing assisted living
centers and in certain units in many of RCA's independent living centers and
nursing homes.
 
    INDEPENDENT LIVING SERVICES.  RCA's independent living centers offer
independent living to seniors. Each center offers a standard package of services
that typically include meal service, laundry and linen service, housekeeping,
organized social activities and transportation. In addition, each of the
independent living facilities offers a menu of separately priced additional
services available at the request of the resident.
 
    RCA derives its patient service revenue, which accounted for approximately
86% and 81% of its total revenue for the nine months ended March 31, 1997 and
fiscal year ended June 30, 1997, respectively, primarily from a combination of
state Medicaid programs, the federal Medicare program and private payment
sources. RCA's revenues are determined by a number of factors, including the
licensed bed capacity of its facilities, occupancy rates at the facilities and
the payor mix. Substantially all of RCA's long-term care beds are certified for
Medicare services, and its patient service revenue attributable to its
assisted/independent living centers is derived exclusively from private pay
sources.
 
    RCA also owns (i) approximately 65% of the outstanding shares of Contour
Capital Stock and (ii) approximately 27% of the outstanding common stock of
In-House Rehab, Inc. (OTC: "IHRB"), which provided rehabilitation services to
approximately 22 of RCA's long-term care facilities as of December 31, 1997.
 
    RCA's offices are located at 6000 Lake Forrest Drive, Suite 200, Atlanta,
Georgia 30328, and its telephone number at that address is (404) 255-7500.
 
    Additional information concerning RCA is included in documents previously
filed by RCA with the Commission and which are incorporated by reference in this
Joint Proxy Statement/Prospectus/Information Statement. See "Available
Information" and "Incorporation of Certain Documents by Reference."

                                    CONTOUR
 
BUSINESS
 
    Contour distributes a full line of disposable medical products and bulk
medical supplies primarily to skilled nursing facilities, home health agencies,
sub-acute care hospitals and other participants in the long-term and alternate
care markets, including RCA. Contour also provides third-party billing services
to the nursing home and home healthcare markets.
 
    Contour markets its REDI NURSE SYSTEM-Registered Trademark- product line,
which provides custom-packaged procedural trays for use in clinics and long-term
care centers as well as by home healthcare nurses, and distributes medical
supplies and equipment produced by other manufacturers. Contour sells its
products to all of RCA's long-term care facilities, as well as to facilities
owned by unaffiliated third parties.
 
    Contour also distributes large quantities of various bulk medical supplies
from over 200 manufacturers. These supplies include items such as examination
gloves, wound care products, urological products and a wide array of durable
medical products such as testing, laboratory and physical therapy and
convalescent products. Contour sells these bulk medical supplies primarily to
long-term care facilities, including the RCA facilities, and home healthcare
providers.
 
    Contour, through a wholly-owned subsidiary, also provides Medicare Part B
billing services for clients, both under its own Medicare provider number and,
at the customer's option, under the customer's provider number on a
fee-for-service basis. As a part of these billing services, Contour provides
Medicare reimbursable wound care products, enteral (tube-feeding/nutritional)
products, ostomy, colostomy and urological products for qualified patients in
its customers' skilled nursing facilities.
 
    Until June 1997, Contour manufactured a full line of orthopedic care and
rehabilitation and disposable surgical products. The orthopedic and
rehabilitative products included pads and positioning aids for X-rays, CAT
scans, mammograms and MRIs; braces for reconstructive rehabilitation after
surgery; and finger spreaders, leg spreaders and leg positioning devices to
prevent atrophy and speed recovery from surgery. Sterile and nonsterile products
such as sponges, swabs, instrument holders, equipment covers and drapes made up
Contour's disposable surgical product line. In June 1997, Contour sold all of
the assets of its manufacturing operations located in Grand Blanc, Michigan and
St. Petersburg, Florida to a third party buyer for cash. Although Contour no
longer manufactures orthopedic care and rehabilitation products, Contour
continues to assemble procedural kits and trays under its REDI NURSE
SYSTEM-Registered Trademark- label and other private labels.
 
    Contour's principal executive offices are located at 6025 Shiloh Road,
Alpharetta, Georgia 30005, and its telephone number at that address is (770)
886-2600.
 
    The percentage of Contour's total revenue attributable to the three product
lines sold by Contour during its last three fiscal years is set forth below.

    BACKGROUND
 
    On September 30, 1994, RCA acquired 899,003 shares of Contour Common Stock
and all 2,000,000 shares of Contour's Class One Convertible Preferred Stock from
three persons who were then officers and directors of Contour. Subsequently, RCA
converted the Class One Convertible Preferred Stock into 2,100,000 shares of
Contour Common Stock. The Contour Common Stock acquired by RCA in these
 
                                      146
<PAGE>
transactions represented approximately 63% of Contour Common Stock outstanding
after the completion of these transactions.
 
    Beginning in 1995, Contour commenced distribution of medical supply products
to nursing home and retirement facilities owned, leased or managed by RCA.
Contour has now expanded this activity to other nursing home operators and other
healthcare providers.
 
    On March 1, 1996, Contour acquired AmeriDyne Corporation ("AmeriDyne")
through a merger with a newly formed, wholly-owned subsidiary of Contour.
Effective as of July 1, 1996, Contour acquired all of the outstanding capital
stock of Atlantic Medical Supply Company, Inc. ("Atlantic Medical"), a
distributor of disposable medical supplies and a provider of third-party billing
services to the nursing home and home healthcare markets. Effective as of July
1, 1996, Contour acquired the remaining minority interest of Facility Supply,
Inc., a majority-owned subsidiary of Atlantic Medical.
 
    PRODUCTS
 
    Contour's bulk medical supply distribution operations involve the purchase
of large quantities of medical supplies from manufacturers and the distribution
of such supplies to nursing homes, home health agencies, hospitals, clinics and
other health care providers. Contour offers over 6,000 products, including
medical/surgical supplies, enteral (nutritional) feeding supplies, personal care
items, incontinent supplies, over-the-counter drugs and respiratory therapy and
ostomy supplies.
 
    During April 1994, Contour introduced its REDI NURSE
SYSTEM-Registered Trademark- products line following the grant of four new
510(K) applications by the United States Food and Drug Administration (the
"FDA"). The REDI NURSE SYSTEM-Registered Trademark- product line consists of
custom-packaged procedural trays that can be used for specified applications,
including wound care, catheter irrigation, catheter insertion, intravenous
therapy and precautionary procedures.
 
    During 1996, Contour began assembling preparatory procedural trays for use
in imaging applications. The FDA granted Contour ten new 510(K) applications for
these trays. Imaging applications in which these trays are utilized include
amniocentesis, arthroscopy, biopsy, mammography and angiography.
 
    SALES, MARKETING AND MARKETS
 
    Contour currently employs one sales vice president, three regional sales
directors, 23 full-time sales associates and five nurse clinicians who are
responsible for soliciting new business, maintaining contact with Contour's
present customer base and directing the efforts of an independent sales
representation organization retained by Contour in July 1994 to market Contour's
REDI NURSE SYSTEM-Registered Trademark- product line to the home healthcare and
nursing home industry in the southeastern United States. Contour's agreement
with such sales organization, which has 11 direct sales representatives who
service approximately 4,500 dealers throughout the Southeast, is for a two-year
period and is automatically renewable unless canceled by either party. Contour
is required to pay such sales organization a commission of 10% of the sales for
which it is responsible.
 
    Historically, Contour has focused on the disposable and limited life medical
product markets for both sterile and non-sterile applications. Contour markets
to three distinct markets: (i) the end user; (ii) the dealer; and (iii) the
value added reseller ("VAR").
 
    END USERS.  The end user market is comprised of three primary care sectors:
hospitals; clinics; and orthopedic care facilities.
 
    DEALERS.  The dealer market covers the full spectrum of Contour's product
lines. Contour sells its products at a discount to volume dealers which sell
Contour's products.
 
                                      147
<PAGE>
    VAR MARKET.  The VAR market consists of original equipment manufacturers
(OEM's) and dealers. Many of the foam products produced by Contour are sold to
OEM's for use in packaging their kits for special surgical procedures.
Additional OEM products include pads and positioning aids for imaging units such
as MRI's, CAT scans and X-rays.
 
    CUSTOMERS
 
    During the years ended June 30, 1997, and June 30, 1996, Contour sold
approximately $7,848,000 and $5,456,000, respectively, in products (primarily
bulk medical supplies) to facilities owned, leased or managed by RCA. Such sales
represented 14% of total sales for the year ended June 30, 1997 and 37% of total
sales for the year ended June 30, 1996. No other individual customer represented
more than 10% of total sales during either of these periods. For the year ended
June 30, 1997, after excluding the revenues generated by sales to RCA, the next
nine largest customers cumulatively represented approximately 15% of total
revenues.
 
    During the six months ended June 30, 1995, RCA accounted for 40% of total
sales. No other individual customer represented more than 10% of total sales
during this period. During the years ended December 31, 1993 and 1994, sales to
Baxter Medical accounted for approximately 14% and 23%, respectively, of
Contour's total sales. No other customer accounted for more than 10% of
Contour's total sales during either year.
 
    COMPETITION
 
    Contour competes with a number of large medical products distributors. In
the home healthcare market, its primary competitors include Gulf South Medical
Supply, National Medical and Southland. In this market, Contour competes by
offering customized ordering programs and other specialized services not offered
by larger competitors.
 
    In the distribution of medical supplies to long-term care providers, its
primary competitors include Gulf South Medical Supply, Redline Medical, General
Medical and Bergen Brunswig Medical Supplies. In addition, there are a number of
smaller, regional competitors. Contour competes by offering an extremely high
level of customer service, as well as customized ordering inventory control
programs and other more specialized services, some of which are not offered by
its competitors.
 
    In the provision of third-party billing services, Contour competes with
several small regional service providers, including Spectrum Health Services,
Appalachian and Grove Medical. Contour believes that it competes favorably in
this market by offering superior customer service and a variety of programs from
which its customers may choose, including fee-for-service billing under the
customer's own Medicare provider number.

    NINE MONTHS ENDED MARCH 31, 1998 COMPARED TO NINE MONTHS ENDED MARCH 31,
     1997
 
    As a result of the factors discussed below, for the nine months ended March
31, 1998, Contour had a net loss of $501,860 compared to net income of $425,257
for the nine months ended March 31, 1997.
 
    Sales increased by $1,342,240 for the nine months ended March 31, 1998 as
compared to the nine months ended March 31, 1997. Revenues in the nine months
ended March 31, 1997 included sales from Contour's manufacturing operation of
approximately $4.1 million. Contour sold its manufacturing assets and
discontinued manufacturing operations in June 1997.
 
    The increase of approximately $5.4 million was the result of an increase in
sales to RCA of approximately $4.2 million, with the balance of the increase, or
approximately $1.2 million, due to the expansion of Contour's customer base.
 
                                      149
<PAGE>
    Gross profit for the nine months ended March 31, 1998, was $10,275,027 or
25.4% of sales, as compared to $11,236,103 or 28.8% of sales, for the same
period of the previous year. The decrease in gross profit as a percentage of
sales is primarily the result of lower gross profit margins typically earned on
the distribution of bulk medical supplies as compared to the gross profit
margins historically earned by Contour's manufacturing enterprise, the assets of
which were sold in June, 1997. Following the sale of its manufacturing assets,
Contour ceased all manufacturing activities.
 
    Operating expenses for the nine month period ending March 31, 1998 were
$10,259,718 as compared to $9,352,812 in 1997. The operating expenses increased
from the same period last year as a result of expenses incurred in the start-up
of two new distribution centers in Randolph, Massachusetts and Portland, Oregon.
The balance of the increase relates to additional costs incurred as a result of
the consolidation of Contour's administrative support functions to the new
corporate office building in Atlanta, Georgia.
 
    YEAR ENDED JUNE 30, 1997 COMPARED TO YEAR ENDED JUNE 30, 1996
 
    As a result of the factors discussed below, for the year ended June 30,
1997, Contour had a net loss of $259,644 compared to a net profit of $527,034
for the year ended June 30, 1996.
 
    Sales increased by $38,900,848 for the year ended June 30, 1997 as compared
to the year ended June 30, 1996. Approximately $8,848,000 of the increase
resulted from sales of bulk medical supplies by AmeriDyne and approximately
$26,757,000 from sales of bulk medical supplies by Atlantic Medical.
Approximately $2,392,000 of the increase resulted from the sales of bulk medical
supplies to RCA. The balance of the increase, or approximately $903,000,
resulted from sales of Contour's manufactured products.
 
    Gross profit for the year ended June 30, 1997 was $13,667,978 or 25.6% of
sales, as compared to $4,051,318 or 27.9% of sales, for the year ended June 30,
1996. The decrease in gross profit as a percentage of sales is primarily the
result of lower gross profit margins typically earned on the distribution of
bulk medical supplies as compared to the gross profit margins historically
earned by Contour's manufacturing enterprise.
 
    Operating expenses for the year ended June 30, 1997 were $12,973,675 as
compared to $3,185,620 for the year ended June 30, 1996. Operating expenses
increased approximately 407% as the result of the AmeriDyne and Atlantic Medical
acquisitions, although as a percent of sales the increase represented a 2.4%
increase. The increase of $9,788,056 in operating expenses is directly related
to the increase of $38,901,000 in revenues. The largest components of operating
expenses are indirect labor (including sales, salaries and commissions),
occupancy expense, depreciation and amortization, and insurance. In particular,
prior to the acquisitions of AmeriDyne and Atlantic Medical, as of July 1, 1997,
Contour did not have a direct sales force and therefore incurred minimal selling
expenses as a percentage of sales. Selling expenses as a percentage of sales
represent approximately 5% of total sales.
 
    Indirect labor, including sales salaries and commissions, increased by
$4,541,291 compared to the same period last year, to approximately $5,792,383.
Occupancy expense, depreciation and amortization and insurance costs increased
by $2,009,873 compared to the same period last year, to approximately
$3,071,917.
 
    Other income and expenses are made up of interest expense, debts recovered
that were previously written off, service charge income, and gains and losses on
the disposition of assets. Interest expense for the year ended June 30, 1997 was
$1,295,557 compared to $170,951 for the same period last year. Interest expense
has increased primarily as a result of (1) the issuance of $5,000,000
convertible debentures on July 12, 1997, bearing interest at 9% per annum; (2)
the issuance of $10,850,000 of notes for the purchase of Atlantic Medical
("Atlantic Notes") and Facility Supply, Inc. ("Facility Notes"); and (3) the
increased usage of Contour's line of credit supporting sales growth throughout
the year. Other income includes $90,672 of service charge income, $18,879 of
debts recovered that were previously written off, and the remaining amount
relates to miscellaneous revenues received during the year. Other expense
includes
 
                                      150
<PAGE>
approximately $35,000 of losses associated with the disposition of assets and
the remaining amount relates to miscellaneous expenses incurred during the
fiscal year.
 
    Gains from the sale of assets for the year ended June 30, 1997 were
approximately $600,000 compared to no such gains for the prior year. These gains
resulted from the sale of Contour's manufacturing assets.
 
    Contour also incurred an expense of $500,000 in financing costs associated
with the guarantee fee paid to RCA for its guarantee of the Atlantic Notes and
the Facility Notes.
 
    As a result of the acquisition of Atlantic Medical on August 11, 1996,
Contour acquired Medicare and trade receivables totaling more than $1.8 million
that were deemed to be uncollectible. The entire amount of these receivables was
reserved at the date of the acquisition. The remaining reserve for uncollectible
accounts represents approximately 16% of trade receivables.
 
    YEAR ENDED JUNE 30, 1996 COMPARED TO THE TWELVE MONTHS ENDED JUNE 30,
1995.
 
    As a result of the factors discussed below, Contour had net income of
$527,034 for the year ended June 30, 1996, as compared to a net loss of $9,997
for the twelve months ended June 30, 1995.
 
    Sales for the year ended June 30, 1996 increased to $14,542,421 as compared
to $5,585,004 for the twelve months ended June 30, 1995, due to growth in sales
volume of the existing product lines and the addition of Contour's new product
line, bulk medical supplies. Approximately $4,844,000 of the sales increase is
attributable to sales of bulk medical supplies and prepacked kits to nursing
homes managed or operated by RCA. The AmeriDyne acquisition on March 1, 1996,
resulted in additional sales of bulk medical supplies of approximately
$3,617,000. The balance of the sales increase, or approximately $496,000,
resulted from increased sales of manufactured foam products and polyethylene
bags.
 
    Gross profit for the year ended June 30, 1996, was $4,051,318 or 27.8% of
sales as compared to $1,739,553 or 31.1% of sales for the twelve months ended
June 30, 1995. The gross profit percentage decreased in 1996 as compared to the
comparable period in 1995 because the sales mix for 1996 was substantially
higher in bulk medical supplies, which have a lower gross profit than the
manufactured products. Approximately $980,000 of the increase in gross profit
for the period ended June 30, 1996 was a result of the additional sales
generated from the AmeriDyne acquisition.
 
    Operating expenses for the year ended June 30, 1996, increased to $3,185,620
as compared to $1,632,015 for the same period in 1995. Total operating expenses
increased approximately $1,533,000 as a result of the increased revenues, but as
a percentage of sales they decreased to approximately 23% of sales in 1996
versus 29% of sales in the same period in 1995. The AmeriDyne acquisition
increased operating expenses by $635,000 for the year ended June 30, 1996. The
largest components of operating expenses are indirect labor (including sales
salaries and commissions), occupancy expense, depreciation and amortization, and
insurance. Operating expenses decreased as a percentage of sales due to
Contour's addition of bulk medical supplies to its product line. While the
distribution of these products produces lower gross margins, this enterprise
requires lower operating expenses to support revenues than Contour's
manufacturing business. As revenues from the sales of bulk medical supplies have
increased at a significantly faster rate than manufacturing (593% growth in
distribution revenues during the twelve months ended June 30, 1996 compared to
the twelve months ended June 30, 1995 versus 12% growth in manufacturing
revenues during the same period), operating expenses as a percentage of total
revenues consequently has declined.
 
    Other income and expenses are made up of interest expense, debts recovered
that were previously written off, service charge income, and gains and losses on
the disposition of assets. Interest expense for the year ended June 30, 1996 was
approximately $171,000 compared to $39,000 for the same period in the previous
year. Interest expense increased primarily as a result of the AmeriDyne
acquisition and an increase in Contour's line of credit during the year from
$250,000 to $500,000. Service charge income and recoveries of bad debts were
approximately $144,000 in the year ended June 30, 1996 compared to $22,000 in
the same period the previous year. These increases were primarily due to the
acquisition of AmeriDyne. Service charge income totaled $117,201 and recoveries
of bad debts previously written off totaled $11,580 for the fiscal year ended
June 30, 1996.
 
                                      151
<PAGE>
    For fiscal year ended June 30, 1996, Contour recorded an allowance for bad
debts of $410,000 when there had been no such allowance recorded in prior
periods primarily as a result of the AmeriDyne acquisition on March 1, 1996.
AmeriDyne maintained an allowance for bad debts of $400,000 at the time
AmeriDyne was acquired by Contour.
 
    Net income before taxes for the year ended June 30, 1996, was $839,200 as
compared to $44,721 for the twelve months ended June 30, 1995. The AmeriDyne
acquisition contributed approximately $295,000 to net income before taxes for
the year ended June 30, 1996.
 
    SIX MONTHS ENDED JUNE 30, 1995 COMPARED TO SIX MONTHS ENDED JUNE 30,
1994.  As a result of the factors discussed below, Contour had net income of
$111,373 for the six months ended June 30, 1995, as compared to a net loss of
$478,798 for the six months ended June 30, 1994.
 
    Sales for the six months ended June 30, 1995 increased to $3,568,459 as
compared to $1,929,200 during the same period in 1994, due to growth in sales
volume of the existing product lines and the addition of bulk medical supply
sales. Approximately $1,426,000 of the sales increase was attributable to sales
of bulk medical supplies and pre-packaged kits to nursing homes managed or
operated by RCA. Approximately $175,000 of these nursing home sales represents
sales of Contour's packaged kits and the remainder of the nursing home sales
represents sales of bulk medical supplies. The remaining $213,000 of the overall
sales increase was due to an increased demand for Contour's existing product
line.
 
    Gross profit for the six months ended June 30, 1995 was $1,024,083, or 28.7%
of sales, as compared to $505,500, or 26.2% of sales, for the six months ended
June 30, 1994. The gross profit percentage remained relatively constant during
the six months ended June 30, 1995 as compared to the comparable period in 1994
because the product mix in both periods included about the same percentage of
REDI NURSE kits which have a lower gross profit than the manufactured products.
The six-month period ended June 30, 1995 included approximately $1,251,000 in
sales of bulk medical supplies which also have a lower gross profit margin, and
the margin during the comparable 1994 period was reduced due to the costs of
developing and shipping numerous prototype kits for customer evaluation and
introduction prior to FDA approvals. In prior years, Contour had higher gross
profit margins because most of Contour's sales were of products manufactured by
Contour.
 
    Operating expenses for the six months ended June 30, 1995 increased to
$841,275 as compared to $657,199 for the same period in 1994. Total operating
expenses increased approximately $184,000 as a result of the increased staffing
necessary to service the increased volumes, but as a percentage of sales such
expenses decreased to approximately 24% of sales in 1995 versus 34% of sales in
the same period in 1994.
 
    Net income before taxes for the six months ended June 30, 1995 was $166,091
as compared to a net loss before income taxes for the six months ended June 30,
1994 of $478,798, after deducting offering costs of $305,731.
 
    YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993.  As a
result of the factors discussed below, Contour had a net loss of $529,182 in
1994 as compared to a net loss of $73,536 in the year ended December 31, 1993.
 
    Sales for 1994 increased by 9% to $3,945,745 as compared to $3,618,359 in
1993 due to growth in sales of existing product lines and increasing sales in
the REDI NURSE product lines, which were introduced during March--April 1994.
 
    Gross profit for 1994 was $1,399,820, or 35.5% of sales, as compared to
$1,557, 109, or 43.0% of sales, in fiscal year 1993. The lower gross profit in
1994 resulted from a change in the sales mix of products and the fact that
Contour's profit margins on the REDI NURSE product lines (which are assembled
and not manufactured) are lower than its margins on products that it
manufactures.
 
    Operating expenses in 1994 were $1,580,385 as compared to $1,623,465 in
1993. The operating expenses decreased primarily due to a reduction of
litigation-related fees and expenses of approximately $55,000.
 
                                      152
<PAGE>
    The net loss before income taxes in 1994 was $529,182 after deducting
offering costs totaling $305,731, as compared to a net loss before income taxes
in 1993 of $125,325.
 
    LIQUIDITY AND CAPITAL RESOURCES
 
    At March 31, 1998, Contour had $9,436,361 of working capital as compared to
$9,524,931 on June 30, 1997.
 
    Operating activities for the nine months ended March 31, 1998, utilized cash
of $6,612,586 as compared to operating activities during the nine months ended
March 31, 1997, which utilized cash of $17,909,984. The decreased use of cash
was primarily due to the acquisition of Atlantic Medical Supply in 1996.
 
    The cash flows utilized for investing activities of $1,276,572 during the
nine months ended March 31, 1998, were a result of the acquisition of additional
equipment for two new distribution centers and costs associated with the
completion of the construction of the new corporate office.
 
    Cash flow of $7,736,005 was provided from financing activities for the nine
month period ending March 31, 1998, whereas for the nine month period ending
March 31, 1997, cash flows from financing activities provided cash of
$19,528,867. During the nine months ended March 31, 1997, $5,000,000 was
provided from debenture borrowings, $10,850,000 was provided by acquisition
notes and $625,506 was provided by the exercise of stock warrants. During the
nine months ended March 31, 1998, $7,415,360 was provided from borrowings and
$320,645 was provided by the exercise of stock options and warrants.
 
    On October 31, 1997, $9.5 million under Contour's line of credit with
Barnett Bank was due for repayment. Contour obtained a forebearance from Barnett
Bank on the line of credit until November 11, 1997, at which time, the line of
credit was renewed and increased to $15 million. Outstanding indebtedness under
the line of credit is due for repayment on October 31, 1998. As of March 31,
1998, $12,678,978 had been borrowed against the line for short-term working
capital and expansion needs.
 
    Contour's line of credit with Barnett Bank and the provisions of the
indenture relating to its 9% convertible debentures, which together total
$17,678,978 of indebtedness, contain certain restrictive covenants. As of March
31, 1998, Contour was out of compliance with a covenant in its line of credit
requiring Contour to maintain a current ratio of no less than 1.50, an EBIT
coverage ratio of no less than 2.0 and an interest coverage ratio of no less
than 4.0. Barnett Bank has granted Contour a waiver of such defaults as of
December 31, 1997 and for the quarter then ended. Also as of June 30, 1997,
September 30, 1997, December 31, 1997, and March 31, 1998 Contour was not in
compliance with certain financial ratios required to be maintained under the
Contour Debentures. On April 2, 1998, Sun, which purchased all of the
Convertible Debentures on December 31, 1997, agreed to waive such defaults until
10 business days after the termination of the Contour Merger Agreement.
 
    On August 6, 1996, Contour acquired all of the outstanding stock of
Atlantic, a distributor of disposable medical supplies and a provider of
third-party billing services to the nursing home and home health care markets.
The acquisition was made retroactively to July 1, 1996. Contour paid $1.4
million in cash and promissory notes totaling $10.5 million (the "Atlantic
Promissory Notes") for the stock of Atlantic, and subsequently paid an
additional $50,000 in cash and issued a promissory note for $350,000 to acquire
a minority interest in a subsidiary of Atlantic. The cash for this transaction
came from the $5 million debenture placement that was completed on July 12,
1996. Contour paid the Atlantic Promissory Notes from the proceeds of a $9.75
million loan from RCA, payable in accordance with the terms of a promissory note
that was convertible into shares of Contour's Common Stock at the option of the
note holder. RCA simultaneously converted this promissory note into 1,950,000
shares of Contour Common Stock. The balance of the Atlantic Promissory Notes was
paid by borrowing under Contour's lines of credit.
 
    As a result of the acquisition of Atlantic, Contour acquired Medicare and
trade receivables totaling more than $1.8 million that were deemed to be
uncollectible. The entire amount of these receivables was
 
                                      153
<PAGE>
reserved at the date of the acquisition. The remaining reserve for uncollectible
accounts represents approximately 16% of trade receivables.
 
    Contour plans to open two additional distribution centers around the United
States during the next nine months. Total capital expenditures anticipated to
fund this expansion will approximate $2 million. Contour has received
commitments from leasing and financing organizations in amounts sufficient to
meet these anticipated needs.
 
    Contour presently does not anticipate any commitments for any other material
capital expenditures.
 
    SEASONALITY AND INFLATION
 
    Contour's business is relatively consistent and stable on a monthly basis
and has not experienced any seasonality over the prior three fiscal years. In
addition, Contour does not believe that inflation has had a material effect on
its results from operations during the past three fiscal years. There can be no
assurance, however, that Contour's business will not be affected by inflation in
the future.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
    The following Unaudited Pro Forma Combined Financial Statements give effect
to (1) the Regency Acquisition as if the Regency Acquisition had occurred on
January 1, 1997 for the Unaudited Pro Forma Combined Statements of Earnings; (2)
the Contour Merger as if the Contour Merger had occurred on March 31, 1998 for
the Unaudited Pro Forma Combined Balance Sheets and January 1, 1997 for the
Unaudited Pro Forma Combined Statements of Earnings; (3) the RCA Merger as if
the RCA Merger had occurred on March 31, 1998 for the Unaudited Pro Forma
Combined Balance Sheets and January 1, 1997 for the Unaudited Pro Forma Combined
Statements of Earnings; (4) the issuance in July 1997 by Sun of $250.0 million
of its 9 1/2% Senior Subordinated Notes due 2007 (the "9 1/2% Notes") for the
Unaudited Pro Forma Combined Statements of Earnings as if the 9 1/2% Notes had
been issued on January 1, 1997; (5) the issuance in May 1998 by Sun of $345.0
million aggregate liquidation value 7% Convertible Trust Issued Preferred
Securities (the "Convertible Preferred Securities") as if the Convertible
Preferred Securites had been issued on March 31, 1998 for the Unaudited Pro
Forma Combined Balance Sheets and January 1, 1997 for the Unaudited Pro Forma
Combined Statements of Earnings; and (6) the issuance in May 1998 by Sun of
$125.0 million of its 9 3/8% Senior Subordinated Notes due 2008 (the "9 3/8%
Notes") (issued at 99.679% of face amount) as if the 9 3/8% Notes had been
issued on March 31, 1998 for the Unaudited Pro Forma Combined Balance Sheets and
January 1, 1997 for the Unaudited Pro Forma Combined Statements of Earnings. In
addition, Unaudited Pro Forma Combined Statements of Earnings for the two years
ended December 31, 1996 are presented to give effect to the combination of Sun
and RCA in a transaction to be accounted for as a pooling-of-interests as if
such combination occurred on January 1, 1995.
 
    The pro forma adjustments are based upon currently available information and
upon certain assumptions that Sun's management believes are reasonable. Sun
accounted for the Regency Acquisition as a purchase of Regency by Sun. Regency's
assets and liabilities were recorded at their initial estimated fair market
values as of October 8, 1997, the date of the Regency Acquisition. The RCA
Merger is expected to be accounted for as a pooling of interests. In the event
the RCA Merger is approved, Sun's purchase of Contour's equity not owned by RCA
will be accounted for by Sun as a purchase by Sun of a minority interest and Sun
and its wholly-owned subsidiaries will own 100% of the outstanding shares of
Contour Common Stock once the RCA Merger is completed. In the event the RCA
Merger is not approved, the Contour Merger will be accounted for as a purchase
of 100% of the outstanding shares of Contour Common Stock. While the RCA Merger
is not dependent upon the acquisition by Sun of the outstanding shares of
Contour Common Stock not owned by RCA, Sun intends to consummate the RCA Merger
only after it acquires the outstanding minority interest in Contour.
 
    The adjustments included in the Unaudited Pro Forma Combined Financial
Statements represent Sun's preliminary determination of these adjustments based
upon available information. There can be no assurance that the actual
adjustments will not differ significantly from the pro forma adjustments
reflected in the Unaudited Pro Forma Combined Financial Statements.
 
    The Unaudited Pro Forma Combined Financial Statements are not necessarily
indicative of the financial position or either future results of operations or
results that might have been achieved if the foregoing transactions had been
consummated as of the indicated dates. The Unaudited Pro Forma Combined
Financial Statements should be read in conjunction with the historical
consolidated financial statements of Sun, Regency, RCA, and Contour, together
with the related notes thereto, which are included or incorporated by reference
in this Joint Proxy Statement/Prospectus/Information Statement.
 
    The Unaudited Pro Forma Combined Financial Statements are based on the
respective historical financial statements and the notes thereto of Sun,
Regency, RCA and Contour, which are included or incorporated by reference in
this Joint Proxy Statement/Prospectus/Information Statement. Sun and Regency
have a fiscal year end of December 31. RCA and Contour have a fiscal year end of
June 30. RCA's and Contour's historical financial statements have been recast to
present their financial statements on a December 31 fiscal year end for purposes
of combining with Sun.

    Costs to be incurred in connection with the RCA Merger and the Contour
Merger are expected to be significant and will be charged against earnings of
the combined company. The charge is currently estimated to be approximately $30
million, and is expected to consist of transaction costs and integration
expenses, including elimination of redundant corporate functions, severance
costs related to headcount reductions, the write-off of certain intangibles and
property and equipment and the Settlement of the Actions (see "Risk
Factors--Risk Factors Concerning RCA and Contour--Shareholder Litigation").
Approximately $25 million of the estimated charges are expected to be charged to
operations in the fiscal quarter in which the RCA Merger is consummated. These
estimated charges of $25 million have been reflected in all Unaudited Pro Forma
Combined Balance Sheets, which include RCA, as a reduction of Other Assets of $9
million, "Accrued Transaction Costs" of $14.5 million, the write-down of
Property and Equipment, net of $1.5 million and a reduction of retained earnings
of $25 million. The remaining $5 million of the estimated charges relating to
the integration expenses are expected to be expensed as incurred, as these costs
are expected to benefit future combined operations. The estimated transaction
costs, integration expenses and Settlement costs have not been reflected in the
Unaudited Pro Forma Combined Statements of Operations. These amounts are
preliminary estimates only and are therefore subject to change. In addition,
there can be no assurance that Sun will not incur additional charges in
subsequent quarters to reflect costs associated with the RCA Merger and the
Contour Merger. The components of the charges are expected to be as follows:

results or financial position that would have been achieved if the Regency
Acquisition, the RCA Merger, the Contour Merger and the issuance of the 9 1/2%
Notes, the Convertible Preferred Securities and the 9 3/8% Notes had occurred as

of the future operating results or financial position of Sun, RCA and Contour.
The Unaudited Pro Forma Combined Statements of Earnings do not reflect the
integration costs related to the Regency Acquisition, the RCA Merger and the
Contour Merger or the benefits or cost savings anticipated to result from
Regency Acquisition, the RCA Merger and the Contour Merger.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
    The immediately preceding unaudited pro forma combined financial statements
give effect to the issuance of the 9 1/2% Notes, the Convertible Preferred
Securities and the 9 3/8% Notes and the Regency Acquisition as if these
transactions occurred on March 31, 1998 for the unaudited combined pro forma
balance sheet (except the 9 1/2% Notes which were issued in July 1997 and the
Regency Acquisition which occurred on October 8, 1997, both of which are
included in Sun's December 31, 1997 balance sheet) and on January 1, 1997 for
the unaudited pro forma combined statements of earnings. In addition, in
connection with the Regency Acquisition, Sun replaced its then-existing credit
facility (the "Old Credit Facility") with a new $1.2 billion credit facility
(the "New Credit Facility").
 
    The unaudited pro forma combined financial statements that reflect the
transactions described above are referred to in subsequent unaudited pro forma
combined financial statement as the "Sun Adjusted" amounts.
 
    Sun retired certain indebtedness of Regency on October 9, 1997, totaling
$160.0 million. The transaction resulted in an extraordinary loss, net of income
tax benefit of $8.8 million, of $17.9 million. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" included in Sun's
Annual Report on Form 10-K for the fiscal year ended December 31, 1997
incorporated by reference into this Joint Proxy Statement/Prospectus/Information
Statement for further discussion of the extraordinary loss.
 
(a) In connection with issuance of the Convertible Preferred Securities, Sun
    capitalized debt issuance costs of approximately $10.9 million, and used the
    net proceeds of $334.2 million to repay (i) $300.0 million under the term
    loan portion of the New Credit Facility and (ii) $34.2 million under the
    revolving credit portion of the New Credit Facility.
 
(b) In connection with the issuance of the 9 3/8% Notes, Sun capitalized debt
    issuance costs of approximately $3.9 million and used the net proceeds of
    $120.7 million to repay borrowings under the revolving credit portion of the
    New Credit Facility.
 
(c) In connection with the issuance of the Convertible Preferred Securities, Sun
    retired $300.0 million under the term loan portion of the New Credit
    Facility. As a result, Sun will record an extraordinary loss in the three
    month period ended June 30, 1998 of approximately $6.6 million, net of an
    income tax benefit of approximately $4.2 million, due to the write-off of
    part of the term loan portion of the New Credit Facility's debt issuance
    costs.
 
(d) In connection with the issuance of the 9 1/2% Notes in July 1997, Sun
    capitalized related debt issuance costs and used the net proceeds of $242.6
    million to repay borrowings under the Old Credit Facility. Interest expense
    up to July 1997, associated with $242.6 million of borrowings under the Old
    Credit Facility, is eliminated in the accompanying unaudited pro forma
    combined statement of earnings. The average variable interest rate for
    borrowings under the Old Credit Facility was 7.1%. The 9 1/2% Notes'
    interest expense of $12.7 million includes amortization of debt issuance
    costs using the effective interest method over the ten-year term of the
    9 1/2% Notes of $0.4 million.
 
(e) Represents the interest expense on the 9 3/8% Notes, including amoritzation
    of debt issuance costs using the effective interest method over the ten-year
    term of the 9 3/8% Notes and amortization of the discount described in
    footnote (f) below.
 
(f) In connection with the issuance of the Convertible Preferred Securities and
    the 9 3/8% Notes, Sun received net proceeds of approximately (i) $334.2
    million from the issuance of the Convertible Preferred Securities and (ii)
    $120.7 million from the issuance of the 9 3/8% Notes (issued at a discount
    of 99.679% of face amount). The net proceeds from the Offerings were used to
    retire $300.0 million of the term loan portion of the New Credit Facility,
    which accrued interest during the period at an

    average variable rate of 8.5%, and to repay $154.8 million of the revolving
    credit portion of the New Credit Facility, which accrued interest during the
    period at an average variable rate of 8.2%.
 
(g) In conjunction with the pay-down of the New Credit Facility, Sun will
    write-off $10.8 million of the $27.6 million debt issuance costs related to
    the New Credit Facility. This adjustment reflects the pro-rata reduction of
    the historical amortization expense of $1.1 million for the three months
    ended March 31, 1998 and $4.2 million for the year ended December 31, 1997.
    The accompanying Unaudited Pro Forma Combined Statement of Earnings does not
    reflect the $6.6 million extraordinary loss, net of income tax benefit of
    $4.2 million, which will be recorded in the three months ended June 30, 1998
    related to the pay-down of the New Credit Facility.

    including amortization of issuance costs of $0.1 million for the year ended
    December 31, 1997.

    (i) Represents acquisition costs including investment banking, legal, and
       accounting fees related to the Regency Acquisition that were funded
       through borrowings under the New Credit Facility.
 
    (ii) Represents the write-down to fair market value of leasehold interests,
       covenants-not-to-compete, deferred financing costs and other intangible
       assets in connection with the Regency Acquisition purchase price
       allocation. Regency's historical balance sheet included these intangible
       assets which were determined by Sun to provide no future benefit and
       therefore were written-off in the purchase price allocation.
 
    (iii) Represents the involuntary employee termination benefits to be paid to
       certain former Regency employees and payments made to certain former
       executives of Regency under pre-existing change of control agreements.
       Regency's corporate office and its long-term care and pharmacy division
       management functions were eliminated in connection with the Regency
       Acquisition. The termination of former Regency employees is expected to
       be completed no later than the second quarter of 1998.
 
    (iv) Sun analyzed the current market rental rates for nursing home
       facilities in the metropolitan and other areas of each state where
       Regency's facilities were located. The average per bed rental rate for
       each Regency facility was compared to the appropriate state region
       average rental rate to determine if the Regency facility rental rates
       were greater or less than the average rental rates. The analysis found
       that 23 facilities had rental rates below their regional average and 24
       facilities had rental rates that were above their regional average. The
       net present value of the positive and negative leasehold interests is
       $13.5 million and $25.8 million, respectively.
 
    (v) Reflects the write-down to fair market value of certain Regency property
       and equipment due to the closure of Regency's corporate office, the
       closure of certain Regency pharmacy facilities and the sale of certain
       former Regency facilities. The reduction to Regency's historical value
       was recorded for the following asset groups: $9.6 million to buildings;
       $7.3 million to equipment; and $6.2 million to construction in progress.
 
    (vi) Represents lease termination fees and reserves for future minimum lease
       payments. Lease termination fees of $1.2 million relate to Regency's
       corporate headquarters and certain Regency facilities that are expected
       to be shut down in March 1998 and June 1998, respectively. The reserve
       for future minimum lease payments ($0.3 million) relates to a separate
       portion of a Regency pharmacy building that has been and will continue to
       be idle; sub-leasing this idle portion of the building is not practical.
 
    (vii) Represents deposits and other assets of Regency which have been
       determined by Sun to provide no future benefit.
 
       This intangible asset will be amortized using the straight-line method
       over a period of 40 years. The allocation of the purchase price of
       Regency is preliminary. Sun is evaluating certain obligations of Regency
       prior to the acquisition and further adjustments to the preliminary

       purchase price allocation may result. Based on the analyses performed to
       date, the Company does not expect that the finalization of the purchase
       price allocation will result in a material adjustment to its financial
       position.
 
(l) Represents the elimination of goodwill amortization associated with
    Regency's historical goodwill balance of $71.6 million. Regency assigned
    useful lives ranging from 15 to 22 years to its goodwill. Amortization was
    based on the straight-line method.
 
(m) Represents the elimination of Regency's historical intangible asset
    amortization for the intangible assets written down in connection with the
    Regency purchase price allocation (see footnote (k)(ii)).
 
(n) Represents the elimination of the depreciation expense resulting from the
    write-down of certain Regency assets to fair market value (see footnote
    (k)(v)).
 
(o) Represents interest expense recognized on borrowings under the New Credit
    Facility for the following purposes (dollar amounts in thousands):

</TABLE>
 
   Pro forma interest expense on borrowings under the New Credit Facility is
    computed using a weighted average interest rate of 8.6%, which is based on
    the LIBOR at March 31, 1998 of 5.7% plus applicable margins as stated in the
    New Credit Facility and includes deferred financing cost amortization of
    $3.1 million.
 
(p) Represents the elimination of historical interest expense related to (i)
    Sun's Old Credit Facility and (ii) Regency's line of credit. A portion of
    Sun's Old Credit Facility interest expense has been eliminated in connection
    with the pro forma adjustment for the 9 1/2% Notes above. In the nine months
    ended September 30, 1997, Sun's average outstanding balance under the Old
    Credit Facility after giving effect to the pro forma repayment attributable
    to the proceeds of the 9 1/2% Notes was $108.6 million. The average balance
    outstanding on Regency's line of credit was $39.0 million for the nine
    months ended September 30, 1997. The weighted average interest rates for the
    nine months ended September 30, 1997 for the Sun and Regency credit
    facilities were 7.1% and 7.5%, respectively.
 
(q) Sun retired Regency's Senior Notes and Junior Notes and replaced such
    amounts with borrowings under its New Credit Facility. The Senior Notes' and
    Junior Notes' interest expense and their related debt cost amortization
    ($0.7 million for the nine months ended September 30, 1997) are replaced by
    interest expense under the term loan portion of the New Credit Facility,
    which accrued interest at an average rate of 8.5%.

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
    The immediately preceding unaudited pro forma combined balance sheet as of
March 31, 1998 gives effect to the Contour Merger as if this transaction
occurred on March 31, 1998. The immediately preceding unaudited pro forma
combined statements of earnings for the three months ended March 31, 1998 and
for the year ended December 31, 1997 give effect to the Contour Merger as if
this transaction occurred on January 1, 1997.
 
(a) The estimated purchase price for Contour is as follows:

                                                                         -----------
Total consideration....................................................  $78,668,000
                                                                         -----------
                                                                         -----------
</TABLE>
 
    The excess of the purchase price over the fair market value of the net
    assets acquired, excluding Contour's historical net goodwill, is equal to
    $72,345,000. This amount would be amortized using the straight-line method
    over a period of 40 years.
 
    Sun has not performed a detailed analysis of the fair market value of
    Contour's assets and liabilities. The pro forma financial statements for the
    Contour Merger reflect the allocation of the excess of the purchase price
    over the net book value of the Contour net assets to goodwill. If Sun
    ultimately directly acquires 100 percent of Contour's outstanding common
    stock, a detailed analysis of the fair market value of Contour's intangible
    assets will be performed.
 
    Under the terms of the Contour Merger, approximately 4,233,000 shares of Sun
    Common Stock are issuable in exchange for outstanding shares of Contour
    Common Stock, Contour Preferred Stock and options and warrants to purchase
    Contour Common Stock.
 
(b) Represents the elimination of Contour's historical goodwill balance of
    $9,896,000 in connection with the purchase price allocation. Amortization
    was based on the straight-line method over 40 years.
 
(c) Under the terms of the Contour Merger, holders of Contour Preferred Stock
    will exchange each of their shares for the number of shares of Sun Common
    Stock equal to the quotient of $4.00 divided by the Sun Market Price. The
    accompanying unaudited pro forma combined financial statements assume that
    the Sun Market Price is equal to $17.875, which was the closing price for
    one share of Sun Common Stock on May 14, 1998. The total consideration
    exchanged for the outstanding Contour Preferred Stock would be $480,000.
 
(d) Holders of Contour's Common Stock will exchange their shares for the number
    of shares of Sun Common Stock equal to the quotient of $8.50 divided by the
    Sun Market Price. The accompanying unaudited pro forma combined financial
    statements assume that the Sun Market Price is equal to $17.875, which was
    the closing price for one share of Sun Common Stock on May 14, 1998. The
    total consideration exchanged for the outstanding Contour Common Stock and
    the outstanding options and warrants to purchase Contour Common Stock would
    be $75.2 million.
 
(e) Represents the elimination of the revenue earned and the related operating
    expenses incurred by the manufacturing division of Contour which was sold in
    June 1997.
 
(f) Represents the amortization of the goodwill recorded in connection with the
    Contour Merger.
 
(g) Represents the elimination of the Contour historical goodwill amortization.
    Contour goodwill of $10.4 million was amortized based on the straight-line
    method over 40 years.
 
(h) Represents the elimination of Contour's non-recurring gain in the sale of
    its manufacturing assets.
 
(i)  Represents the income tax benefit associated with the additional expenses
    presented, after eliminating the impact of the non-deductible goodwill
    amortization, using an assumed 39% blended statutory tax rate.

    RCA Merger. This will result in Contour becoming an indirectly wholly-owned
    subsidiary of Sun. The total consideration for the purchase of the Contour
    equity not owned by RCA is approximately $32.3 million. The total
    consideration paid would exceed the balance of the Contour minority interest
    by $27.8 million. This amount will be recorded as goodwill and amortized
    using the straight-line method over 40 years. Under the terms of the Contour
    Merger, approximately 1,468,000 shares of Sun Common Stock are issuable in
    exchange for outstanding Contour Common Stock and Contour Preferred Stock
    assuming that the RCA Merger is completed after the Contour Merger. The
    estimated transaction costs associated with the Contour Merger are $1.0
    million.
 
(e) Represents the payment of the RCA class action litigation settlement (see
    "Risk Factors--Risk Factors Concerning RCA and Contour--Shareholder
    Litigation").
 
(f) Represents the estimated acquisition costs to be incurred by Sun in order to
    effect the integration of RCA into Sun's operations.
 
(g) Under the terms of the RCA Merger, holders of RCA's Series AA Redeemable
    Preferred Stock will exchange each of their shares for the number of shares
    of Sun Common Stock equal to the quotient of $10.00 divided by the average
    of the last reported sales prices of one share of Sun Common Stock on the
    NYSE during the period of the 20 most recent trading days ending five
    business days before the RCA Effective Time (as defined). The accompanying
    unaudited Pro Forma Combined Financial Statements assume that the Sun Market
    Price is equal to $17.875, which was the closing price for one share of Sun
    Common Stock on May 14, 1998. In the event the Sun Market Price exceeds
    $24.20 or is less than $19.80, the RCA Series AA Exchange Ratio shall be
    equal to 0.413 or 0.505, respectively,

                        DESCRIPTION OF SUN CAPITAL STOCK
 
    Pursuant to its certificate of incorporation, Sun is authorized to issue a
total of 105,000,000 shares of capital stock, consisting of 100,000,000 shares
of Sun Common Stock, and 5,000,000 shares of preferred stock, par value $0.01
per share. If the proposed amendment to Sun's Certificate of Incorporation is
approved by Sun's stockholders, Sun will be authorized to issue a total of
155,000,000 shares of capital stock, consisting of 150,000,000 shares of Sun
Common Stock, and 5,000,000 shares of preferred stock, par value $0.01 per
share. See "Additional Matters Submitted to a Vote of Sun
Stockholders--Additional Proposal No. 1--Approval of the Amendment to the Sun
Certificate of Incorporation."
 
SUN COMMON STOCK
 
    As of May 1, 1998, there were 49,607,942 outstanding shares of Sun Common
Stock held by approximately 4,993 holders of record, and an additional 2,122,101
shares of Sun Common Stock held as treasury stock. The holders of shares of Sun
Common Stock have one vote per share on all matters to be voted upon by
stockholders. Subject to any preferences, voting powers, qualifications and
special or relative rights or privileges of any holders of preferred stock,
holders of Sun Common Stock are entitled, among other things, to dividends if,
when and as declared from time to time by Sun's board of directors out of assets
legally available therefor after payment of debts and expenses. Sun's ability to
pay dividends is restricted by the terms of its existing credit facility and
agreements governing certain outstanding indebtedness of Sun. With the exception
of the rights issued pursuant to the Sun's Stockholders' Rights Plan, holders of
shares of Sun Common Stock have no preemptive or other rights to subscribe for
additional shares. The Sun Common Stock is neither redeemable nor convertible,
and there are no sinking fund provisions. Upon the voluntary or involuntary
liquidation of Sun, holders of Sun Common Stock are entitled to receive all
remaining assets of Sun available for distribution to stockholders after payment
to creditors or of preference amounts owed to holders of any preferred stock.
 
    All of the outstanding shares of Sun Common Stock are fully paid and
nonassessable.
 
    The shares of Sun Common Stock do not have cumulative voting rights, which
means that the holders of more than 50% of the shares voting can elect all the
directors if they so choose, and, in such event, the holders of the remaining
shares cannot elect any directors. No stockholder owns more than 50% of the
outstanding Sun Common Stock.
 
PREFERRED STOCK
 
    A Certificate of Designation relating to a particular series of preferred
stock will be filed with the Commission at or prior to the sale of the shares of
such series of preferred stock. Sun's Certificate of Incorporation authorizes
the issuance of up to 5,000,000 shares of preferred stock, par value of $.01 per
share, none of which is currently outstanding. Of the 5,000,000 shares of Sun's
authorized preferred stock, Sun has reserved for issuance 1,000,000 shares of
Series A Preferred Stock, par value $0.01 per share, issuable upon exercise of
Sun's Preferred Share Purchase Rights (see the description of Sun's Preferred
Stock Purchase Rights contained in its Registration Statement on Form 8-A filed
on June 6, 1995, as amended by Form 8-A/A-1 filed on August 17, 1995,
incorporated by reference herein), and up to 300,000 shares of Sun Preferred
Stock issuable in connection with the RCA Merger. Sun's preferred stock may be
issued from time to time in one or more series without stockholder approval.
Subject to limitations prescribed by law, Sun's board of directors is authorized
to determine the voting powers (if any), designation, preferences and relative,
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, for each series of preferred stock that may be issued,
and to fix the number of shares of each such series. Thus, Sun's board of
directors, without stockholder approval, could authorize the issuance of
preferred stock with voting, conversion and other rights that could adversely
affect the voting power and other rights of holders of Sun Common Stock or other
series of preferred stock or that could have the effect of delaying, deferring
or preventing a change in control of Sun. Among other
 
                                      177
<PAGE>
things, the preferred stock may be issued with extraordinary voting, dividend,
redemption or conversion rights. Sun has no plans to issue any shares of
preferred stock, other than the shares of Sun Preferred Stock to be issued in
the RCA Merger. See "Risk Factors--Anti-Takeover Provisions; Possible Issuance
of Preferred Stock."
 
SERIES B CONVERTIBLE PREFERRED STOCK
 
    Upon the filing of a Certificate of Designations with respect to the Sun
Preferred Stock prior to the consumation of the RCA Merger, Sun will have
authorized 450,001 shares of Sun Preferred Stock, none of which are issued and
outstanding as of the date hereof. The following description of the preferences,
limitations and relative rights of the Sun Preferred Stock is qualified in its
entirety by reference to the Certificate of Designations of Series B Convertible
Preferred Stock of Sun Healthcare Group, Inc. (the "Certificate of
Designations"), a copy of which is filed as an exhibit to the Registration
Statement of which this Joint Proxy Statement/Prospectus/Information Statement
forms a part.
 
    DIVIDENDS.  The holders of shares of Sun Preferred Stock are not entitled to
receive any dividends.
 
    CONVERSION RIGHTS.  Each share of Sun Preferred Stock may be converted at
the option of the holder thereof at any time and from time to time, and without
the payment of any additional consideration thereof, into the number of fully
paid, nonassessable shares of Sun Common Stock as shall be determined by (i)
dividing (A) $10.00 by (B) the lesser of (a) $7.638125, or (b) 85% of the
average closing bid price of the RCA Common Stock as reported by the NYSE for
the five consecutive trading days immediately prior to the RCA Effective Time,
(ii) adding (x) $10.00 per share multiplied by 8% per annum from September 25,
1996 through the RCA Effective Time (y) divided by the number determined
pursuant to (i)(B) above, and (iii) multiplying such number by the RCA Common
Exchange Ratio (the "Conversion Price"). Each share of Sun Preferred Stock not
previously converted at the election of the holder thereof shall automatically
be converted into shares of Sun Common Stock pursuant to the above formula on
October 2, 1998. No fractional shares of Sun Common Stock will be issued upon
conversion of Sun Preferred Stock. In lieu of any fractional shares to which the
holder would otherwise be entitled, the Corporation shall round up to the
nearest whole share.
 
    The Conversion Price shall be adjusted to reflect, as deemed equitable and
appropriate by the corporation, any stock dividend, stock split or share
combination of the Sun Common Stock. In the event of a merger, reorganization,
recapitalization or similar event of or with respect to Sun (a "Corporate
Change") (other than a Corporate Change in which all or substantially all of the
consideration received by the holders of Sun's equity securities upon such
Corporate Change consists of cash or assets other than securities issued by the
acquiring entity or any affiliate thereof), the Sun Preferred Stock must be
assumed by the acquiring entity and thereafter the Sun Preferred Stock will be
convertible into such class and type of securities as the holder would have
received had the holder converted the Sun Preferred Stock immediately prior to
such Corporate Change, as appropriately adjusted to equitably reflect the
Conversion Price and any stock dividend, stock split or share combination of the
Sun Common Stock after such corporate event, and in any such case appropriate
provisions shall be made with respect to the rights and interests of the holders
of the Sun Preferred Stock to the end that the provisions hereof shall
thereafter be applicable, as nearly as may be practicable in relation to any
securities thereafter deliverable upon the exercise hereof.
 
    VOTING RIGHTS.  The holders of Sun Preferred Stock have the same voting
rights as holders of Sun Common Stock, except as set forth below or as otherwise
from time to time required by law. The holders of Sun Preferred Stock are
entitled to vote with the holders of Sun Common Stock, voting together with such
holders as one class, on all matters for which the holders of Sun Common Stock
are entitled to vote, with each share of Sun Preferred Stock entitled to a
number of votes equal to the number of shares of Sun Common Stock into which it
is then convertible using the record date for the taking of such vote of
stockholders as the date as of which the Conversion Price is calculated. The
affirmative vote or consent of
 
                                      178
<PAGE>
the holders of at least a majority of the outstanding shares of Sun Preferred
Stock, voting separately as a class, is required for an amendment, alteration or
repeal of Sun's Certificate of Incorporation if, and only if, the amendment,
alteration or repeal adversely affects the powers, preferences or special rights
of the Sun Preferred Stock. To the extent that under Delaware law the vote of
the holders of the Sun Preferred Stock, voting separately as a class, is
required to authorize a given action of Sun, the affirmative vote or consent of
the holders of at least a majority of the outstanding shares of the Sun
Preferred Stock constitutes the approval of such action by the class. Holders of
the Sun Preferred Stock are entitled to notice of all shareholders meetings or
written consents with respect to which they would be entitled to vote, which
notice would be provided pursuant to the Sun's by-laws and applicable statutes.
 
    LIQUIDATION PREFERENCE.  In the event of any liquidation, dissolution or
winding-up of Sun, either voluntary or involuntary, the holders of shares of Sun
Preferred Stock are entitled to receive, immediately after distributions of
senior securities required by the Sun's certificate of incorporation, and prior
and in preference to any distribution to junior securities but in parity with
any distribution to parity securities, an amount per share equal to the sum of
(i) $10.00 and (ii) an amount equal to $0.40 per annum for the period from
October 2, 1996 to the date of such liquidation, dissolution or winding-up. If
upon the occurrence of such event the assets and funds thus distributed among
the holders of the Sun Preferred Stock and parity securities are insufficient to
permit the payment to such holders of the full preferential amounts due to the
holders of the Sun Preferred Stock and the parity securities, respectively, then
the entire assets and funds of Sun legally available for distribution shall be
distributed among the holders of the Sun Preferred Stock and the parity
securities, pro rata, based on the respective liquidation amounts to which such
series of stock is entitled by the Sun's Certificate of Incorporation.
 
    A consolidation or merger of Sun with or into any other corporation or
corporations, or a sale, conveyance or distribution of all or substantially all
of the assets of Sun or the effectuation by Sun of a transaction or series of
related transactions in which more than 50% of the voting power of Sun is
disposed of, shall not be deemed to be a liquidation, dissolution or winding-up
within the meaning of this section, but shall instead be treated as follows: In
the event that Sun shall make any distribution of its assets upon or with
respect to the Sun Common Stock, as a liquidating or partial liquidating
dividend, or other than as a dividend payable out of earnings or any surplus
legally available for dividends under the laws of the state of incorporation of
Sun, each holder of Sun Preferred Stock then outstanding shall receive the
amount of such assets which would be distributed to such holder if he had
exercised his right to convert immediately prior to the record date for such
distribution or, in the absence of a record date, immediately prior to the date
of such distribution.
 
    PROTECTIVE PROVISIONS.  So long as shares of Sun Preferred Stock are
outstanding, Sun may not take any action that would impair the rights of the
holders of the Sun Preferred Stock and may not without first obtaining the
approval (by vote or written consent, as provided by law) of all of the holders
of the then outstanding shares of Sun Preferred Stock: (i) alter or change the
rights, preferences or privileges of the shares of Sun Preferred Stock or any
other securities so as to affect adversely the Sun Preferred Stock; (ii) create
any new class of stock having a preference over, or being on a parity with, the
Sun Preferred Stock with respect to distributions pursuant to the immediately
preceding section; or (iii) do any act or thing which would result in taxation
of the holders of shares of Sun Preferred Stock under Section 305 of the
Internal Revenue Code of 1986, as amended (or any comparable provision of the
Internal Revenue Code as hereinafter from time to time amended).
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Sun Common Stock is ChaseMellon
Shareholders Services L.L.C. located in Ridgefield Park, New Jersey.

<PAGE>
                        COMPARISON OF STOCKHOLDER RIGHTS
 
    The rights of Sun stockholders are governed by the certificate of
incorporation (the "Sun Certificate") and bylaws of Sun and the laws of the
State of Delaware. The rights of RCA shareholders are governed by the articles
of incorporation (the "RCA Articles") and bylaws of RCA and the laws of the
State of Colorado. The rights of Contour stockholders are governed by the
articles of incorporation (the "Contour Articles") and bylaws of Contour and the
laws of the State of Nevada. After the RCA Effective Time and Contour Effective
Time, the rights of RCA shareholders and Contour stockholders, as the case may
be, who become Sun stockholders will be governed by the Sun Certificate, the Sun
bylaws and the laws of the State of Delaware. In certain respects, rights of Sun
stockholders, RCA shareholders and Contour stockholders are similar. While it is
not practical to describe all of the changes in the rights of RCA shareholders
and Contour stockholders that will result from the application of Delaware law
in lieu of Colorado law and Nevada law, respectively, and the differences
between the Sun Certificate and bylaws, the RCA Articles and bylaws and the
Contour Articles and bylaws, as applicable, the following is a summary of
certain significant differences. It should be understood that such descriptions
of the differences is a summary only and does not purport to be a complete
description of the differences between Delaware, Colorado and Nevada corporation
laws.
 
    The Sun Certificate authorizes the issuance of 100,000,000 shares of Sun
Common Stock and authorizes the issuance of 5,000,000 shares of preferred stock.
If the proposed amendment to the Sun Certificate is approved by Sun's
stockholders, Sun will be authorized to issue 150,000,000 shares of Sun Common
Stock. See "Additional Matters Submitted to a Vote of Sun
Stockholders--Additional Proposal No. 1--Approval of the Amendment to the Sun
Certificate of Incorporation." Sun has authorized two series of preferred stock,
none of which are outstanding. See "Description of Sun Capital Stock."
Accordingly, the rights of holders of Sun Common Stock are subject to superior
rights and preferences of holders of any outstanding series of Sun preferred
stock with respect to dividends and distributions upon liquidation. The relative
rights and preferences of any series of Sun preferred stock issued in the future
may be established by the Sun board of directors without stockholder action, and
shares of such series, when and if issued, could have dividend, liquidation,
voting, and other rights superior to those of Sun Common Stock.
 
    The RCA Articles currently authorize the issuance of 300,000,000 shares of
RCA Common Stock and 40,000,000 shares of preferred stock, of which 300,000
shares have been designated as RCA Series AA Preferred Stock and 1,000,000
shares have been designated as RCA Series F Preferred Stock. As of December 31,
1997, 14,792,434 shares of RCA Common Stock were outstanding, 120,000 shares of
RCA Series AA Preferred Stock were outstanding and 298,334 shares of RCA Series
F Preferred Stock were outstanding.
 
    The Contour Articles authorize the issuance of 76,000,000 shares of Contour
Common Stock and 1,265,000 shares of Contour Preferred Stock. As of December 31,
1997, 8,293,331 shares of Contour Common Stock were outstanding and 135,000
shares of Contour Preferred Stock were outstanding.
 
    ACTION WITHOUT A MEETING.  Delaware law provides that, unless otherwise
provided in the certificate of incorporation, any action which may be taken at
any annual or special meeting of stockholders of a corporation may be taken
without a meeting, without prior notice, and without a vote, if a consent or
consents in writing, setting forth the actions so taken, shall be signed by the
holders of outstanding stock having not less than the minimum number of votes
that would be necessary to authorize or take such action at a meeting at which
all shares entitled to vote thereon were present and voted. The Sun Certificate
provides that any action required or permitted to be taken by stockholders shall
be taken only at a duly called special or annual meeting of the stockholders.
Stockholders have no authority to take action by written consent unless approved
in advance by Sun's board of directors.
 
                                      180
<PAGE>
    Colorado law only permits actions to be taken by written consent if all of
the shareholders entitled to vote thereon sign such consent. RCA's bylaws permit
actions by written consent provided notice is given within ten days to
shareholders who do not consent, stating the action taken and, if such action is
a merger, dissenting stockholders' rights.
 
    Under Nevada law, unless otherwise provided in the articles of
incorporation, stockholders may take action without a meeting, without prior
notice and without a vote, upon the written consent of stockholders having not
less than the minimum number of votes that would be necessary to authorize the
proposed action at a meeting at which all shares entitled to vote were present
and voted. Contour's bylaws provide that any action that may be taken or is
required to be taken at any annual or special meeting of stockholders may be
taken without a meeting.
 
    ANNUAL MEETINGS.  If a Delaware corporation fails to hold an annual meeting
for a period of 13 months after its last annual meeting, the Court of Chancery
may summarily order a meeting to be held upon the application of any stockholder
or director. The shares of stock represented at such meeting, either in person
or by a proxy, and entitled to vote thereof, shall constitute a quorum for the
purpose of such meeting.
 
    Colorado law provides that if an annual meeting of shareholders has not been
held within the earlier of six months after the end of the corporation's fiscal
year or 15 months after its last annual meeting, a shareholder entitled to
participate in an annual meeting may demand an annual meeting of shareholders by
written notice of demand to the district court of the county where the
corporation's principal or registered office is located.
 
    Under Nevada law, if a corporation fails to elect directors within 18 months
after the last election of directors then the district court has jurisdiction,
upon application of any one or more stockholders entitled to exercise at least
15 percent of the voting power, to order the election of directors.
 
    SPECIAL MEETINGS.  Delaware law provides that special meetings of the
stockholders may be called by the board of directors or by such person or
persons as may be authorized by the certificate of incorporation or by the
bylaws. Sun's bylaws authorize the Chairman of the Board, the President or a
majority of the board of directors to call a special meeting of stockholders.
 
    Colorado law provides that special meetings of the shareholders may be
called by any of the following: the board of directors; a person authorized in
the bylaws or in resolutions of the board of directors to call special meetings
or a shareholder or shareholders holding 10% or more of the voting power of all
shares entitled to vote. RCA's bylaws also authorize RCA's President to call a
special meeting of shareholders.
 
    Nevada law does not specifically provide for, or prohibit, special meetings
of stockholders. Contour's bylaws provide that special meetings of the
stockholders may be called for any purpose at any time by the President, board
of directors, or the holders of not less than 10% of all shares entitled to vote
at the meeting.
 
    PROXIES.  Both Delaware and Colorado law permit proxies of indefinite
duration. In the event that the proxy is indefinite as to its duration, Colorado
law provides that it will be valid for eleven months and Delaware law provides
that it will be valid for three years. Nevada law permits proxies of up to seven
years in duration. In the event that the proxy is silent as to duration, Nevada
law provides that it will be valid for six months.
 
    PREEMPTIVE RIGHTS.  Under Delaware law, no stockholder shall have any
preemptive right to subscribe to any additional issue of stock or to any
security convertible into such stock unless, and to the extent that, such right
is expressly granted in the certificate of incorporation. The Sun Certificate
does not grant preemptive rights to Sun's stockholders.
 
                                      181
<PAGE>
    Under Colorado law, a shareholder of a corporation has a preemptive right to
acquire unissued shares or rights to purchase such shares of the corporation
before the corporation may offer them to other persons, unless such rights are
denied or limited in the articles of incorporation. The RCA Articles provide
that shareholders have no preemptive rights to purchase any shares or securities
of the corporation which it may issue or sell, except as may be otherwise
provided in a separate shareholder agreement.
 
    Under Nevada law, stockholders do not have preemptive rights to acquire
unissued shares except to the extent authorized in the articles of
incorporation. The Contour Articles do not entitle stockholders as a matter of
right to acquire additional shares of any class of stock of the corporation.
 
    CUMULATIVE VOTING.  Under Delaware law, stockholders do not have cumulative
voting rights unless the rights are granted to them in the corporation's
certificate of incorporation. If cumulative voting is provided for in the
certificate or articles of incorporation, each holder of stock shall be entitled
to as many votes as shall equal the number of votes which he or she would be
entitled to cast for the election of directors with respect to his or her shares
of stock multiplied by the number of directors to be elected by him or her, and
that he or she may cast all such votes for a single director, or may distribute
them among the number to be voted for, or for any two or more of them as he or
she may see fit. The Sun Certificate does not provide for cumulative voting.
 
    Under Colorado law, cumulative voting is generally mandatory for
corporations incorporated after December 31, 1958 unless specifically prohibited
in the corporation's articles of incorporation. The RCA Articles do not provide
for cumulative voting rights in the election of directors.
 
    Under Nevada law, cumulative voting of stock applies only when so provided
in the articles of a corporation. The Contour Articles do not provide for
cumulative voting rights in the election of directors.
 
    DISSOLUTION.  A Delaware corporation may be dissolved by the voluntary
action of the holders of a majority of the outstanding shares of the corporation
entitled to vote thereon. Additionally, a Delaware corporation may be dissolved
without the action of the directors if all of the stockholders entitled to vote
thereon shall consent in writing. A Colorado corporation and a Nevada
corporation may be dissolved upon a proposal of the corporation's board of
directors and the affirmative vote of the holders of a majority of the voting
power of all stock entitled to vote.
 
    REQUIRED VOTE FOR AUTHORIZATION OF CERTAIN ACTIONS.  Under Delaware law, the
vote of a simple majority of the outstanding shares of Sun Common Stock entitled
to vote thereon is required to approve a merger or consolidation, or the sale,
lease, or exchange of substantially all of Sun's corporate assets.
 
    Colorado law generally requires the affirmative vote of the holders of a
majority of the outstanding shares of each class entitled to vote to approve a
merger or share exchange. In certain circumstances, the holders of outstanding
shares of a class of capital stock of a Colorado corporation are entitled to
vote as a separate voting group, regardless of whether the articles of
incorporation provide that such shares of capital stock are entitled to vote.
However, no vote of shareholders of a Colorado corporation is required to
approve a merger if (i) that corporation is the surviving corporation of the
merger, (ii) the articles of incorporation of the surviving corporation, with
certain exceptions, will not differ from its articles of incorporation before
the merger, (iii) each shareholder of the surviving corporation whose shares are
outstanding immediately before the merger will hold the same number of shares,
with identical designations, preferences, limitations, and relative rights,
immediately after the merger, and (iv) the number of shares of the corporation
to be issued in the merger, or to be issuable upon conversion of any convertible
instruments to be issued in the merger, does not exceed 20% of the voting stock
of that corporation outstanding immediately before the merger.
 
    Except with respect to certain mergers between a parent and subsidiary
corporation, under Nevada law a merger generally requires the affirmative vote
of a majority of the outstanding shares entitled to vote thereon. Holders of
stock which is not by its terms entitled to vote on such a transaction are
entitled to
 
                                      182
<PAGE>
notice of the meeting at which the proposed transaction is considered. Nevada
law does not require a stockholder vote of the surviving corporation in a
merger, however, if (a) the merger agreement does not amend the existing
certificate of incorporation, (b) each outstanding or treasury share of the
surviving corporation before the merger is unchanged after the merger and (c)
the number of shares to be issued by the surviving corporation in a merger does
not exceed 20% of the shares outstanding immediately prior to such issuance.
 
    DISSENTERS' RIGHTS.  Under Delaware law, holders of shares of any class or
series have the right, in certain circumstances, to dissent from a merger or
consolidation by demanding payment in cash for their shares equal to the fair
value (excluding any appreciation or depreciation as a consequence or in
expectation of the transaction) of such shares, as determined by agreement with
the corporation or by an independent appraiser appointed by a court in an action
timely brought by the corporation or the dissenters. Delaware law grants
dissenters' appraisal rights only in the case of mergers or consolidations and
not in the case of a sale or transfer of assets or a purchase of assets for
stock regardless of the number of shares being issued. Further, no appraisal
rights are available for shares of any class or series listed on a national
securities exchange or designated as a national market system security on the
Nasdaq National Market or held of record by more than 2,000 stockholders, unless
the agreement of merger or consolidation converts such shares into anything
other than (a) stock of the surviving corporation, (b) stock of another
corporation which is either listed on a national securities exchange or
designated as a national market system security on the Nasdaq National Market or
held of record by more than 2,000 stockholders, (c) cash in lieu of fractional
shares, or (d) some combination of the above. In addition, dissenters' rights
are not available for any shares of the surviving corporation if the merger did
not require the vote of the stockholders of the surviving corporation.
 
    Under Colorado law, any shareholder of a corporation is entitled to receive
payment of the fair value of such shareholder's shares of capital stock if such
shareholder properly dissents from (i) any merger, share exchange or
confirmation of a sale, lease or exchange of all or substantially all of the
assets of the corporation or an entity controlled by the corporation not made in
the regular course of business for which a vote of such shareholder is required,
(ii) any corporate action that results in an amendment of the articles of
incorporation, which materially and adversely affects rights with respect to a
dissenter's shares because it alters or abolishes a preferential right of the
shares, creates, alters or abolishes a right in respect of redemption, excludes
or limits the rights of the shares to be voted on any matter or to cumulate
votes, or a reverse stock split that reduces the number of shares owned by the
shareholder to a fraction of a share or to scrip if the fractional share or
scrip so created is to be acquired for cash or the scrip is to be voided, or
(iii) any other corporate action to the extent provided by the bylaws or by
resolution of the board of directors. See the more detailed discussion of the
procedures for asserting dissenters' rights under "The RCA Merger--Dissenters'
Rights."
 
    Nevada law provides that stockholders have the right, in some circumstances,
to dissent from certain corporate reorganizations and to instead demand payment
of the fair cash value of their shares. Similar to Delaware law, Nevada law
generally does not provide for dissenters' rights with respect to a merger or
consolidation by a corporation, the shares of which are either listed on a
national securities exchange or held by at least 2,000 stockholders of record if
stockholders receive shares of the surviving corporation or of a listed or
widely held (at least 2,000 stockholders) corporation; however, both Delaware
law and Nevada law have certain exceptions to such rule and the principal
difference between such exceptions is that under Nevada law holders do not have
appraisal rights if they receive cash, either exclusively or in addition to
surviving corporation stock or widely held stock. See the more detailed
discussion of the procedures for asserting dissenters' rights under "The Contour
Merger--Dissenters' Rights."
 
    CONFLICTS OF INTEREST.  Under Delaware law, a contract or transaction
between a corporation and one or more of its directors or officers, or between a
corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall not be void or voidable solely for
that reason, or solely because the
 
                                      183
<PAGE>
director or officer was present at or participated in the meeting of the board
or committee thereof which authorized the contract or transaction, or solely
because his or her vote was counted for such purpose, provided that the contract
or transaction is (i) authorized in good faith by the board of directors, (ii)
ratified by the corporation's stockholders, or (iii) fair to the corporation.
Common or interested directors may be counted in determining the presence of a
quorum at a meeting of the board which authorizes the contract or transaction.
 
    In general, Colorado's conflicts of interest statute is the same as
Delaware's statute, except that Colorado's conflict of interest statute does not
cover transactions between the corporation and its officers.
 
    Nevada's conflicts of interest statute is the same as Delaware's, except
that the Nevada statue does not invalidate transactions in which a director or
officer has an interest if the conflict is not known at the time of the
transaction.
 
    DIVIDENDS AND DISTRIBUTIONS.  A Delaware corporation may make repurchases or
redemptions that do not impair capital and may pay dividends out of any surplus
account (generally the stockholders' equity of the corporation less the par
value of the capital stock outstanding) or, if no surplus exists, out of net
profits of the current and preceding fiscal years (provided that certain
provisions must be made for preferences of outstanding stock having a
liquidation preference). To determine the surplus, assets and liabilities are
valued at their current fair market value. Assuming that such assets have a fair
market value greater than their book value and their liabilities have not
increased in value to a greater extent, such revaluation will increase the
surplus of the corporation and thereby permit the corporation to pay an
increased dividend and/or to repurchase a greater number of shares.
 
    Under both Colorado and Nevada law, distributions to shareholders or
stockholders of a corporation may not be made if any such distribution would
render the corporation unable to meet its liabilities in the ordinary course of
business or, if as a result of such distribution, the excess of the
corporation's assets over its liabilities would be less than the liquidation of
all shares having a preference on liquidation over the class or series to which
the distribution is made. Under both Colorado law and Nevada law, corporations
may pay dividends out of surplus or, if no surplus exists, out of net profits
for the fiscal year in which the dividend is declared and/or the preceding
fiscal year.
 
    ANTI-TAKEOVER PROVISIONS.  Section 203 of the DGCL, which is currently
applicable to Sun, prohibits certain publicly held Delaware corporations from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person or
entity became an interested stockholder, unless, among other exemptions (i) the
business combination is approved by the board of directors prior to the date the
interested stockholder attained such status, and authorized by the holders of
two-thirds of the outstanding voting stock not owned by the interested
stockholders or (ii) the interested stockholder acquired 85% or more of the
outstanding voting stock of Sun in the transaction in which the person or entity
became an interested stockholder. For purposes of Section 203, a "business
combination" is defined broadly to include mergers, asset sales and other
transactions resulting in a financial benefit to the interested stockholder.
Subject to certain exceptions, an "interested stockholder" is a person or entity
who, together with affiliates and associates, owns or within the three years
immediately preceding a business combination did own 15% or more of the
corporation's outstanding voting stock.
 
    Colorado does not have a comparable statute.
 
    Certain provisions of Nevada law disallow the exercise of voting rights with
respect to "control shares" of an "issuing corporation" held by an "acquiring
person," unless such voting rights are conferred by a majority vote of the
disinterested stockholders or if, prior to the acquiring person's acquisition of
the control shares, the articles of incorporation or bylaws of the issuing
corporation state that such provisions of Nevada law do not apply to the issuing
corporation. Contour's bylaws contain such a statement with regard to the
transactions contemplated by the Contour Merger Agreement. Nevada law also
contains
 
                                      184
<PAGE>
provisions restricting the ability of a corporation to engage in any combination
with an interested stockholder (i) unless three years have elapsed since the
time such interested stockholder becomes such and the combination complies with
certain fair price specifications or (ii) unless the board of directors of the
corporation approved of the interested stockholder's acquisition of shares.
Nevada law defines an interested stockholder, generally, as a person who owns
10% or more of the outstanding shares of such corporation's voting stock. Sun
would be considered an interested stockholder of Contour under Nevada law.
However, because the Contour board approved the acquisition of the shares of
Contour Capital Stock pursuant to the Contour Merger Agreement by Sun, the
provisions of Nevada law restricting a combination involving Sun do not apply.
 
    CHARTER AMENDMENTS.  Delaware law does not provide for stockholders,
independently from the board, to propose amendments to the certificate of
incorporation. Delaware law generally requires that, absent a greater
requirement in the certificate or articles of incorporation, a majority of the
outstanding stock entitled to vote thereon, and a majority of the outstanding
stock of each class entitled to vote as a class, must vote in favor of the
amendment.
 
    Under Colorado law, the holders of shares representing at least 10% of the
vote entitled to be cast on the amendment may propose an amendment to the
articles of incorporation. Colorado law generally requires that the amendment be
approved by a majority of the votes entitled to be cast on the amendment by any
voting group with respect to which the amendment would create dissenters'
rights.
 
    Under Nevada law, unless the articles or bylaws otherwise provide,
amendments to the articles generally require the approval of the holders of a
majority of the outstanding stock entitled to vote thereon, and if such
amendments would increase or decrease the number of authorized shares of any
class or series or the par value of such shares or would adversely affect the
shares of such class or series, the holders of the outstanding shares of a class
shall be entitled to vote as a class to approve the amendment.
 
    AMENDMENT OF BYLAWS.  Delaware law provides that the power to adopt, amend
or repeal bylaws shall be in the stockholders entitled to vote; provided,
however, any corporation may, in its certificate of incorporation, confer the
power to adopt, amend, or repeal bylaws upon the directors. The fact that such
power has been or conferred upon the directors shall not divest the
stockholders, nor limit their power to adopt, amend or repeal bylaws.
 
    Generally, Colorado law provides that the board may amend or repeal the
bylaws unless the articles reserve the power exclusively to the shareholders or
the bylaw expressly provides that the board shall not amend or repeal the bylaw.
A corporation's shareholders may amend or repeal the corporation's bylaws even
though the bylaws may also be amended or repealed by its board of directors.
 
    Under Nevada law, unless the articles or bylaws otherwise provide,
amendments to the certificate or articles generally require the approval of the
holders of a majority of the outstanding stock entitled to vote thereon.
Contour's bylaws provide that by the affirmative vote of a majority of the
voting stock, stockholders may alter, amend or repeal, or adopt additional,
bylaws. The Contour bylaws allow the directors to act similarly by an
affirmative vote of a majority of the board.
 
    RIGHTS PLAN.  Delaware, Colorado and Nevada law allow for the adoption by a
company of a rights plan providing for the issuance of additional shares in the
event of acquisition by a third party of a significant portion of the company's
outstanding equity. Sun has adopted such a stockholder rights plan. See the
description of Sun's Preferred Stock Purchase Rights contained in its
Registration Statement on Form 8-A filed on June 6, 1995, as amended by Form
8-A/A-1 filed on August 17, 1995, incorporated by reference herein. Neither RCA
nor Contour has adopted such plans.
 
    DIRECTORS.  Delaware and Colorado law provide that a corporation's board of
directors shall consist of at least one member and that the number of directors
be fixed in the corporation's certificate or articles of incorporation, as the
case may be. Nevada similarly provides that a board of directors shall consist
of at
 
                                      185
<PAGE>
least one member, but that the number shall be fixed in the corporation's
bylaws. The Sun Certificate, the RCA bylaws and the Contour Articles provide
that the number of directors constituting the respective boards will be fixed
from time to time by resolution of the respective boards. Sun's board currently
consists of eleven directors and is classified into three classes of directors,
each serving three-year terms. A classified board of directors could make it
more difficult for stockholders, including those holding a majority of the
outstanding shares, to force an immediate change in the composition of a
majority of the board of directors. Staggered terms moderate the pace of changes
in the board of directors by extending the minimum time required to elect a
majority of directors to two years. RCA's board consists of five directors and
is not classified. Contour's board currently consists of three directors and is
not classified.
 
    REMOVAL OF DIRECTORS; FILLING VACANCIES ON THE BOARD OF DIRECTORS.  Under
Delaware law, any director of a classified board of directors may be removed
only for cause by the holders of a majority of the shares entitled to vote at an
election of directors. Under Colorado law, any director may be removed with or
without cause by a majority of votes cast. Under Nevada law, any director may be
removed from office with or without cause upon the vote of stockholders
representing not less than two-thirds of the voting power of the issued and
outstanding stock entitled. While the Sun Certificate is silent as to the
filling of vacancies on the Sun board of directors, the Sun Certificate provides
that any director or the entire Sun board may be removed with or without cause
by the holders of a majority of shares entitled to vote at an election of
directors. Contour's bylaws provide for similar removal of directors. RCA's
bylaws provide for removal in the manner provided for by Colorado law.
 
    Delaware, Colorado and Nevada law generally provide that all vacancies on
the board of directors, including vacancies caused by an increase in the number
of authorized directors, may be filled by a majority of the remaining directors
even if they are less than a quorum. The Sun Certificate and RCA's and Contour's
bylaws follow this language and further provide that any such elected director
shall hold office for a term expiring at the annual meeting at which the term of
the class to which he has been elected expires.
 
    LIMITATION ON DIRECTORS' LIABILITY.  Delaware, Colorado and Nevada law each
permit a corporation to include a provision in its certificate or articles of
incorporation eliminating or limiting the personal liability of a director for
damages for breach of the director's fiduciary duty subject to certain
limitations. Sun's certificate limits liability to the fullest extent of
applicable law. RCA's bylaws limit director liability for actions taken in good
faith if the director exercised reasonable care. Contour's bylaws limit director
liability for actions taken in compliance with the director's duties.
 
    INDEMNIFICATION.  Delaware, Colorado and Nevada law each permit a
corporation to indemnify officers, directors, employees and agents for actions
taken 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, which they had no reasonable cause to believe was unlawful.
Each state's laws provide that a corporation may advance expenses of defense and
must reimburse a successful defendant for expenses, including attorneys' fees,
and both states permit a corporation to purchase and maintain liability
insurance for its directors and officers. Each state's laws provide that
indemnification may not be made for any claim, issue or matter as to which a
person has been adjudged by a court of competent jurisdiction, to be liable to
the corporation, unless and only to the extent a court determines that the
person is entitled to indemnify for the such expenses as the court deems proper.
The Sun Certificate, RCA's bylaws and Contour's bylaws permit indemnification to
the fullest extent of the applicable law.

           ADDITIONAL MATTERS SUBMITTED TO A VOTE OF SUN STOCKHOLDERS
 
ADDITIONAL PROPOSAL NO. 1--APPROVAL OF THE AMENDMENT TO THE SUN CERTIFICATE OF
  INCORPORATION
 
    On August 7, 1997, Sun's board of directors adopted, subject to stockholder
approval, an amendment to Article Fourth of Sun's Certificate of Incorporation
to increase the authorized number of shares of Sun Common Stock from 100,000,000
to 150,000,000. The stockholders are asked to approve the adoption of this
amendment to Sun's Certificate of Incorporation.
 
DESCRIPTION OF THE PROPOSAL
 
    The text of Article Fourth of Sun's Certificate of Incorporation, as it is
proposed to be amended, is as follows:
 
    "FOURTH.  The aggregate number of shares of capital stock which the
Corporation shall have authority to issue is One Hundred Fifty-Five Million
(155,000,000) shares, divided into One Hundred Fifty Million (150,000,000)
shares of common stock with One Penny ($.01) par value, and Five Million
(5,000,000) shares of preferred stock with One Penny ($.01) par value."
 
    The additional shares of Sun Common Stock to be authorized by adoption of
the proposed amendment would have rights identical to the currently outstanding
Sun Common Stock. Adoption of the proposed amendment and issuance of the Sun
Common Stock would not affect the rights of the holders of currently outstanding
shares of Sun Common Stock, except for effects incidental to increasing the
number of shares of Sun Common Stock outstanding, such as dilution of the
earnings per share and voting rights of current holders of Sun Common Stock. The
holders of Sun Common Stock do not have preemptive rights to subscribe for the
additional shares of Sun Common Stock proposed to be authorized. If the
amendment is adopted, it will become effective upon filing of a Certificate of
Amendment of Sun's Certificate of Incorporation with the Secretary of State of
Delaware.
 
    Under Sun's current Certificate of Incorporation, Sun has the authority to
issue 100,000,000 shares of Sun Common Stock and 5,000,000 shares of preferred
stock, $0.01 par value per share. At the close of business on May 20, 1998,
49,622,661 shares of Sun Common Stock were outstanding, net of treasury shares.
Accordingly, as of May 20, 1997, after taking into account the 4,873,687 shares
of Sun Common Stock reserved for issuance upon the exercise of options and the
granting of other awards under Sun's stock benefit plans, the 540,000 shares of
Sun Common Stock reserved for issuance pursuant to outstanding warrants, the
831,197 shares of Sun Common Stock potentially issuable upon the conversion of
Sun's 6 1/2% convertible subordinated debentures, the 3,814,103 shares of Sun
Common Stock potentially issuable upon the conversion of Sun's 6% convertible
subordinated notes, the 17,138,220 shares of Sun Common Stock potentially
issuable upon the conversion of Sun's Convertible Preferred Securities and the
estimated 10,927,130 shares of Sun Common Stock potentially issuable pursuant to
the RCA Merger and the Contour Merger, there remained approximately 11,890,959
shares of Sun Common Stock available for issuance. Accordingly, this amendment
in Sun's Certificate of Incorporation is not necessary for the consummation of
the RCA Merger and the Contour Merger.
 
    The purpose of the increase in authorized shares is to provide sufficient
shares of Common Stock to, among other things, provide additional shares of Sun
Common Stock that could be issued to raise additional funds to repay certain
indebtedness outstanding under Sun's $1.2 billion credit facility, of which
approximately $1.1 billion was outstanding as of March 31, 1998, and for other
corporate purposes without further stockholder approval unless required by
applicable law or regulation. Future uses for these additional shares could
include effecting acquisitions of other businesses or properties, paying stock
dividends, subdividing outstanding shares through stock splits, providing equity
incentives to employees, officers or directors, and securing additional
financing for the operation of Sun through the issuance of additional shares.
Sun's board of directors believes that it is in Sun's best interests to have
additional shares of Sun Common Stock authorized at this time in order to
alleviate the expense and delay of holding a
 
                                      187
<PAGE>
special meeting of stockholders if and when there is a need to issue additional
shares of Sun Common Stock. Sun is currently evaluating several financing
alternatives. Sun anticipates completion of one or more of these financing
events during 1998.
 
    The additional shares of Sun Common Stock that would become available for
issuance if the proposed amendment were adopted could also be used by Sun to
oppose a hostile takeover attempt or delay, defer or prevent changes of control
of Sun. For example, without further stockholder approval, Sun's board of
directors could strategically sell shares of Sun Common Stock in a private
transaction to purchasers who would oppose a takeover or favor Sun's current
board of directors. Although this proposal to increase the number of authorized
shares of Sun Common Stock has been prompted by business and financial
considerations, not by the threat of any hostile takeover attempt (nor is Sun's
board of directors currently aware of any such attempts directed at Sun),
stockholders nevertheless should be aware that approval of the proposal could
facilitate future efforts by Sun to deter, defer or prevent changes of control
of Sun, including transactions in which Sun's stockholders might otherwise
receive a premium for their shares over then-current market prices.
 
VOTE REQUIRED: RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    Approval of the proposal to increase the number of authorized shares of Sun
Common Stock will require the affirmative vote of a majority of the outstanding
shares of Sun Common Stock. Abstentions and broker non-votes will have the
effect of negative votes.
 
    THE BOARD OF DIRECTORS OF SUN RECOMMENDS A VOTE "FOR" APPROVAL OF THE
AMENDMENT TO SUN'S CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF
AUTHORIZED SHARES OF SUN COMMON STOCK (AS SET FORTH IN ANNEX H HERETO).

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. NATURE OF OPERATIONS
 
    Contour Medical, Inc. ("Contour Medical" or the "Company") was incorporated
in Nevada in April 1987 and in 1989 conducted an initial public offering. The
Company's common stock is traded in the over-the-counter market, and since
September 21, 1995, has been traded on the Nasdaq Small-Cap Market under the
symbol "CTMI." Approximately 62% of the Company's common stock is owned by
Retirement Care Associates, Inc. ("Retirement Care"), a publicly-held company
engaged in the management and operation of retirement care and long-term nursing
home facilities in the Southeastern United States. The Company's corporate
offices are located in Alpharetta, Georgia.
 
    Prior to 1996, the Company's revenues were derived predominantly through its
manufacturing facilities, Contour Fabricators, Inc. ("CFI") and Contour
Fabricators of Florida, Inc. ("CFFI"), located in Grand Blanc, Michigan and St.
Petersburg, Florida, respectively. These companies manufactured disposable
surgical procedure products and custom packaged procedural trays for use in
specialized medical applications. During 1997, the assets related to these
businesses were sold to an unrelated party.
 
    In 1996, the Company acquired AmeriDyne Corporation ("AmeriDyne"), a
Jackson, Tennessee-based distributor of bulk medical supplies primarily to home
health agencies and hospitals. Sales from AmeriDyne included in the consolidated
statements of operations amounted to approximately $14,464,000 and $3,616,000
for 1997 and 1996, respectively. (See Note 13).
 
    In 1997, the Company acquired Atlantic Medical Supply Company, Inc.
("Atlantic Medical"), an Augusta, Georgia-based distributor of medical supplies
and ancillary products to long-term care providers. Sales from Atlantic
Medical's facilities in Georgia, North Carolina and Florida amounted to
approximately $26,757,000 in 1997. (See Note 12).
 
    On June 27, 1997, the Company sold all of its manufacturing assets,
including equipment, accounts receivable, customer lists, prepaid assets,
deposits, inventory and other assets. These assets were sold for $3,350,000 in
cash to an unrelated third party, RawCar, L.L.P. The Company retained all
liabilities related to the assets sold. Upon completion of this sale, the
Company ceased all manufacturing activity.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Principles of Consolidation--The consolidated financial statements include
the accounts of Contour Medical, Inc. and its wholly-owned subsidiaries,
Atlantic Medical Supply Company, Inc., AmeriDyne Corporation, Contour
Fabricators, Inc., and Contour Fabricators of Florida, Inc., collectively
referred to as "the Company." All material intercompany accounts and
transactions have been eliminated in the consolidation.
 
    Management Estimates--The preparation of the consolidated financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
consolidated assets and liabilities and disclosure of contingent assets and
liabilities at the date of the consolidated financial statements. Estimates also
affect the reported amounts of consolidated revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    Revenue Recognition--Sales are recognized upon shipment of products to
customers.
 
    Trade Receivables--The Company uses the allowance method to provide for
uncollectible accounts. Allowance for doubtful accounts approximated $2,805,000
and $410,000 as of June 30, 1997 and 1996, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Inventories--Inventories are valued at lower of cost (first-in, first-out)
or market. AmeriDyne inventories are valued at the lower of average cost or
market.
 
    Property and Equipment--Property and equipment are stated at cost.
Depreciation is computed over the estimated useful lives of the assets by
accelerated methods for financial reporting and income tax purposes.
 
    Fair Value of Financial Instruments--Financial instruments held by the
Company at June 30, 1997 include cash, deposits and long-term debt. Management
believes that, considering current terms of similar financial instruments, the
carrying value of the Company's financial instruments approximated their fair
values at June 30, 1997.
 
    Goodwill--The Company has classified as goodwill the cost in excess of fair
value of the net assets of Atlantic Medical and AmeriDyne acquired in purchase
transactions. Goodwill is being amortized on the straight-line method over 40
years. Amortization charged to continuing operations amounted to approximately
$240,000 and $11,000 for the years ended June 30, 1997 and 1996, respectively.
The Company periodically reviews goodwill to assess recoverability, and any
impairment would be recognized in operating results if anticipated undiscounted
future cash flows of the underlying assets do not exceed the book value of the
goodwill and the underlying assets.
 
    Offering Costs--Fees, costs and expenses related to offerings of securities
are deferred and charged against the proceeds therefrom or, if the offering is
unsuccessful, charged to operations. Costs of $257,000 related to a proposed
public offering were deferred at December 31, 1993 and charged to operations in
the second quarter of 1994, when the offering was abandoned. Deferred costs at
December 31, 1994, related to the private placement discussed in Note 9, were
charged against the proceeds therefrom in 1995.
 
    Deferred Loan Costs--Fees, costs and expenses related to the issuance of
long-term debt are deferred and amortized over the term of the related debt
using the straight-line method. Amortization of deferred loan costs charged to
operations in 1997 approximated $46,000.
 
    Income Taxes--Income taxes are accounted for using the asset and liability
method for financial accounting and reporting purposes. Accordingly, deferred
tax assets and liabilities are recognized for temporary differences between the
financial reporting basis of assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date. A valuation allowance is provided for
deferred tax assets when management considers it more likely than not that some
portion or all of the asset will not be realized.
 
    Change in Year-End--The Company changed its fiscal year-end from December 31
to June 30 during 1995. Accordingly, the June 30, 1995 statements of operations,
stockholders' equity and cash flows are for the six months then ended.
 
    Reclassifications--Certain 1996 and 1995 amounts have been reclassified to
conform with the 1997 presentation. These reclassifications had no effect on
operations.
 
    In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS
128"), which is required to be adopted for the fiscal years ending after
December 15, 1997. SFAS No. 128 supersedes APB Opinion No. 15, "Earnings

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Per Share" and specifies the computation, presentation and disclosure
requirements for earnings per share ("EPS") for entities with publicly held
common stock or potential common stock. SFAS 128 essentially replaces the
primary EPS and fully diluted EPS presentations under APB Opinion No. 15 with a
basic EPS and a diluted EPS calculation. The Company adopted the provisions of
SFAS 128 effective December 31, 1997. In accordance with SFAS 128, all prior
periods presented have been restated to reflect the provisions thereof.
 
    In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income," which establishes standards for the
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. There currently are no additional
disclosures in the financial statements of the Company that are expected to be
required by the provisions of this statement.
 
    In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"), which changes the way public companies report information about
segments of their business in annual financial statements and requires segment
information in quarterly reports to shareholders. SFAS 131 also requires that
public companies report certain information about their products and services,
the geographic areas in which they operate and their major customers. SFAS 131
is effective for fiscal years beginning after December 15, 1997. The Company has
not determined what additional disclosures may be required by the provisions of
SFAS 131.
 
3. RELATED PARTY TRANSACTIONS
 
    During 1995, the Company began distributing medical supplies to health care
facilities owned, leased, or managed by Retirement Care. Sales to these
facilities approximated $7,848,000, $5,456,000 and $1,426,000 for the years
ended June 30, 1997, 1996 and the six-month period ended June 30, 1995,
respectively. Trade accounts receivable of approximately $5,135,000 and
$1,918,000 related to these health care facility sales are outstanding as of
June 30, 1997 and 1996, respectively. Additionally, the Company had an
outstanding loan receivable due from Retirement Care of approximately $973,000
as of June 30, 1997 with interest at prime and $619,000 as of June 30, 1996
which is due on demand with no stated interest rate.

price of the common stock for the 21 consecutive trading days following the
Company's public press release of the 1997 fiscal year end financial results is
less than the then-existing conversion price. If an adjustment is required, then
the Company must furnish to the holders of the debentures a statement, signed by
the Chief Executive Officer of the Company, of the facts creating such
adjustment and specifying the resultant adjusted conversion price then in
effect. The adjustment will only be made to adjust the conversion price to a
price that is less than the then-existing conversion price. The conversion
feature of the 9% Convertible Debentures has not been triggered.

    As of June 30, 1997, the Company had net operating loss carryforwards for
tax purposes, expiring at various dates ending July 30, 2012, of approximately
$1.1 million which includes approximately $516,000 attributable to Contour
Medical, Inc. for the period prior to January 1, 1993. Due to certain change of
ownership requirements of Section 382 of the Internal Revenue Code, utilization
of the Company's operating losses is expected to be limited to approximately
$414,000 per year. The deferred tax asset related to the tax benefit of these
losses has been offset by a valuation allowance due to uncertainty of
realization. The valuation allowance increased approximately $89,000 during 1997
and decreased approximately $112,000 during 1996.
 
    The income tax benefit arising from any utilization of the net operating
losses attributable to CMI will be credited to additional paid-in capital when
recognized. During 1996, the income tax benefit of utilization of net operating
losses attributable to the Company of approximately $126,000 was credited to
paid-in capital.

to determine, at the time of option, whether the option will be an Incentive

14. PRO-FORMA PRESENTATION OF STOCK COMPENSATION COSTS
 
    In October 1995 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based
Compensation." This new standard defines a fair value based method of accounting
for an employee stock option or similar equity instrument. This statement gives
entities a choice of recognizing related compensation expense by adopting the
new fair value method or to continue to measure compensation using the intrinsic
value approach under Accounting Principles Board (APB) Opinion No. 25, the
former standard. If the former standard for measurement is elected, SFAS No. 123
requires supplemental disclosure to show the effects of using the new
measurement criteria. This statement is effective for the Company's 1997 fiscal
year. The Company intends to continue using the measurement prescribed by APB
Opinion No. 25, and accordingly, this pronouncement will not affect the
Company's financial position or results of operations.

    For all years presented, no convertible securities were included in the
computation of diluted EPS because their effect would have been anti-dilutive.
During certain periods presented, options and warrants have not been included in
the computation of diluted EPS because the exercise price of such options and
warrants was greater than the average market price of the common stock
underlying such options and warrants during such period, or because their effect
would have been anti-dilutive.

    places (the "SERIES AA EXCHANGE RATIO");
 
        (c) Each share of Series F Preferred Stock issued and outstanding
    immediately prior to the Effective Time (other than any shares of Series F

    Dissenting Shares) and all rights in respect thereof shall, pursuant to the
    terms thereof, be assumed by Parent (and amended so as to provide voting
    rights on an as-converted basis) and thereafter be convertible into the

        (d) Each share of Company Capital Stock held in the treasury of the
    Company and each share of Company Capital Stock owned by Parent or any

    SECTION 3.02.  EXCHANGE OF SHARES OTHER THAN TREASURY SHARES AND DISSENTING
SHARES.  Subject to the terms and conditions hereof, at or prior to the
Effective Time, Parent shall appoint an exchange agent to effect the exchange of
shares of Company Capital Stock (other than Dissenting Shares) for Parent Common
Stock (and shares of Parent New Preferred) in accordance with the provisions of
this Article III (the "EXCHANGE AGENT"). From time to time after the Effective
Time, Parent shall deposit, or cause to be deposited, certificates representing
Parent Common Stock (and shares of Parent New Preferred) for conversion of
shares of Company Capital Stock (other than Dissenting Shares) in accordance
with the provisions of Section 3.01 (such certificates, together with any
dividends or distributions with respect thereto, being herein referred to as the
"EXCHANGE FUND"). Commencing immediately after the Effective Time and until the
appointment of the Exchange Agent shall be terminated, each holder of a
certificate or certificates theretofore representing shares of Company Capital
Stock (other than Dissenting Shares) may surrender the same to the Exchange
Agent and, after the appointment of the Exchange Agent shall be terminated, any
such holder may surrender any such certificate to Parent. Such holder shall be
entitled upon such surrender to receive in exchange therefor a certificate or
certificates representing the number of full shares of Parent Common Stock (or
shares of Parent New Preferred) into which the shares of Company Capital Stock
theretofore represented by the certificate or certificates so surrendered shall
have been converted in accordance with the provisions of Section 3.01, together
with a cash payment in lieu of fractional shares, if any, in accordance with
Section 3.04, and all such shares of Parent Common Stock (or shares of Parent
New Preferred) shall be deemed to have been issued at the Effective Time. Until
so surrendered and exchanged, each outstanding certificate which, prior to the
Effective Time, represented issued and outstanding shares of Company Capital
Stock shall be deemed for all corporate purposes of Parent, other than the
payment of dividends and other distributions, if any, to evidence ownership of
the number of full shares of Parent Common Stock (or shares of Parent New
Preferred) into which the shares of Company Capital Stock theretofore
represented thereby shall have been converted at the Effective Time. Unless and
until any such certificate theretofore representing shares of Company Capital
Stock is so surrendered, no dividend or other distribution, if any, payable to
the holders of record of Parent Common Stock (or shares of Parent New Preferred)
as of any date subsequent to the Effective Time shall be paid to the holder of
such certificate in respect thereof. Upon the surrender of any such certificate
theretofore representing shares of Company Capital Stock, however, the record
holder of the certificate or certificates representing shares of Parent Common
Stock (or shares of Parent New Preferred) issued in exchange therefor shall
receive from the Exchange Agent or from Parent, as the case may be, payment of
the amount of dividends and other distributions, if any, which as of any date
subsequent to the Effective Time and until such surrender shall have become
payable with respect to such number of shares of Parent Common Stock (or shares
of Parent New Preferred) ("PRESURRENDER DIVIDENDS"). No interest shall be
payable with respect to the payment of Presurrender Dividends upon the surrender
of certificates theretofore representing shares of Company Capital Stock. After
the appointment of the Exchange Agent shall have been terminated, such holders
of Parent Common Stock (or shares of Parent New Preferred) which have not
received payment of Presurrender Dividends shall look only to Parent for payment
thereof. Notwithstanding the foregoing provisions of this Section 3.02, risk of
loss and title to such certificates representing shares of Company Capital Stock
shall pass only upon proper delivery of such certificates to the Exchange Agent,
and neither the Exchange Agent nor any party hereto shall be liable to a holder
of shares of Company Capital Stock for any Parent Common Stock (or shares of
Parent New Preferred) or dividends or distributions thereon delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law or to a transferee pursuant to Section 3.03. In the event that this
Agreement shall have been terminated pursuant to Section 9.01 hereof, the
Company and Parent shall cause the Exchange Agent to use its commercially
reasonable efforts to effect the prompt return of stock certificates
representing shares of Company Capital Stock to the holders thereof.
 
    SECTION 3.03.  STOCK TRANSFER BOOKS.  (a) At the Effective Time, each of the
stock transfer books of the Company with respect to shares of Company Capital
Stock shall be closed, and there shall be no further registration of transfers
of shares of Company Capital Stock thereafter on the records of any such
 
                                       9
<PAGE>
stock transfer books. In the event of a transfer of ownership of shares of
Company Capital Stock that is not registered in the stock transfer records of
the Company, at the Effective Time, a certificate or certificates representing
the number of full shares of Parent Common Stock (or shares of Parent New
Preferred) into which such shares of Company Capital Stock shall have been
converted shall be issued to the transferee together with a cash payment in lieu
of fractional shares, if any, in accordance with Section 3.04, and a cash
payment in the amount of Presurrender Dividends, if any, in accordance with
Section 3.02, if the certificate or certificates representing such shares of
Company Capital Stock is or are surrendered as provided in Section 3.02,
accompanied by all documents required to evidence and effect such transfer and
by evidence of payment of any applicable stock transfer tax.
 
    (b) Notwithstanding anything to the contrary herein, certificates
surrendered for exchange by any person constituting a Pooling Affiliate of the
Company shall not be exchanged until Parent shall have received from such person
an executed Company Affiliate Agreement, as provided in Section 7.03(a).
 
    SECTION 3.04.  NO FRACTIONAL SHARE CERTIFICATES.  Unless Parent otherwise
determines, no scrip or fractional share certificates for Parent Common Stock
shall be issued upon the surrender for exchange of certificates evidencing
shares of Company Capital Stock, and an outstanding fractional share interest
shall not entitle the owner thereof to vote, to receive dividends or to any
rights of a stockholder of Parent or of the Surviving Corporation with respect
to such fractional share interest. In lieu of fractional shares, each holder of
shares of Company Capital Stock who, except for the provisions of this Section
3.04, would be entitled to receive a fractional share of Parent Common Stock
shall, upon surrender of the certificate or certificates representing shares of
Company Capital Stock, be entitled to receive an amount in cash (rounded to the
nearest whole cent), without interest, equal to the product obtained by
multiplying (a) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Company Capital
Stock held at the Effective Time by such holder) by (b) the closing price for a
share of Parent Common Stock on the NYSE on the first business day immediately
prior to the Effective Time. At or prior to the Effective Time, Parent shall pay
to the Exchange Agent an amount in cash (the "CASH DEPOSIT") sufficient for the
Exchange Agent to pay each holder of Company Capital Stock the amount of cash in
lieu of fractional shares to which such holder is entitled pursuant to this
Section 3.04. As soon as practicable after the determination of the amount of
cash, if any, to be paid to holders of Company Capital Stock with respect to any
fractional share interests, the Exchange Agent shall make available such
amounts, net of any required withholding, to such holders of Company Capital
Stock, subject to and in accordance with the terms of Section 3.02. In no event
shall either (i) the total cash consideration paid to holders of Company Capital
Stock in lieu of fractional shares exceed one percent (1%) of the value of the
total consideration issued to holders of Company Capital Stock in exchange for
their Company Capital Stock or (ii) any holder of Company Capital Stock,
directly or indirectly, receive cash in an amount equal to or greater than the
value of one full share of Parent Company Stock.
 
    SECTION 3.05.  OPTIONS AND WARRANTS TO PURCHASE COMPANY COMMON STOCK.  At
the Effective Time, each option or warrant granted by the Company to purchase
shares of Company Common Stock (each, a "COMPANY STOCK OPTION") which is
outstanding and unexercised immediately prior to the Effective Time shall be
assumed by Parent and converted into an option or warrant to purchase shares of
Parent Common Stock in such number and at such exercise price as provided below
and otherwise having the same terms and conditions as in effect immediately
prior to the Effective Time (except to the extent that such terms, conditions
and restrictions may be altered in accordance with their terms as a result of
the Merger):
 
        (a) the number of shares of Parent Common Stock to be subject to the new
    option or warrant shall be equal to the product of (i) the number of shares
    of Company Common Stock subject to the original option or warrant and (ii)
    the Common Exchange Ratio;
 
                                       10
<PAGE>
        (b) the exercise price per share of Parent Common Stock under the new
    option or warrant shall be equal to the quotient of (i) the exercise price
    per share of Company Common Stock under the original option or warrant
    divided by (ii) the Common Exchange Ratio; and
 
        (c) upon each exercise of options or warrants by a holder thereof, the
    aggregate number of shares of Parent Common Stock deliverable upon such
    exercise shall be rounded down, if necessary, to the nearest whole share and
    the aggregate exercise price shall be rounded up, if necessary, to the
    nearest cent.
 
    The adjustments provided herein with respect to any options which are
"incentive stock options" (as defined in Section 422 of the Code) shall be
effected in a manner consistent with the requirements of Section 424(a) of the
Code.
 
    SECTION 3.06.  CERTAIN ADJUSTMENTS.  If between the date of this Agreement
and the Effective Time, the outstanding shares of Company Capital Stock or
Parent Common Stock shall be changed into a different number of shares by reason
of any reclassification, recapitalization, split-up, combination or exchange of
shares, or any dividend payable in stock or other securities shall be declared
thereon with a record date within such period, or the number of shares of
Company Capital Stock on a fully diluted basis is in excess of that specified in
Section 4.03 and disclosed in 4.03 of the Company Disclosure Schedule
(regardless of whether such excess is a result of an additional issuance of
capital stock or a correction to such Sections), but excluding options permitted
to be issued pursuant to Section 6.01(b) hereof, then the exchange ratios
established pursuant to the provisions of Section 3.01 shall be adjusted
accordingly to provide to the holders of Company Capital Stock the same economic
effect as contemplated by this Agreement prior to such reclassification,
recapitalization, split-up, combination, exchange, dividend or increase.
 
    SECTION 3.07.  UNDISTRIBUTED AMOUNTS.  Any portion of the Exchange Fund or
the Cash Deposit which remains undistributed for six months after the Effective
Time shall be delivered to Parent, and any holder of Company Capital Stock who
has not theretofore complied with the provisions of this Article III shall
thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock or Parent New Preferred, as the case may be, or any cash in lieu of
fractional shares of Parent Common Stock and any Presurrender Dividends.
 
    SECTION 3.08.  DISSENTING SHARES.  Notwithstanding any provision of Section
3.01 hereof to the contrary, shares of Company Capital Stock which are held by
holders of such shares who have not voted in favor of the Merger, who are
entitled to dissent and who have delivered a written notice of intent to demand
payment for such shares in the manner provided in Article 113 of the Business
Corporation Act ("DISSENTING SHARES"), shall not be converted into or exchanged
for or represent the right to receive any shares of Parent Common Stock (or
shares of Parent New Preferred), unless such holder fails to perfect or
effectively withdraws or loses such rights to payment. If, after the Effective
Time, such holder fails to perfect or effectively withdraws or loses such right
to payment, then such Dissenting Shares shall thereupon be deemed to have been
converted into and exchanged pursuant to Section 3.01 hereof, as of the
Effective Time, for the right to receive shares of Parent Common Stock (or
shares of Parent New Preferred) issued in the Merger to which the holder of such
shares of Company Capital Stock is entitled, without any interest thereon. The
Company shall give Parent prompt notice of any notices and demands received by
the Company for payment for shares of Company Capital Stock, and Parent shall
have the right to participate in all negotiations and proceedings with respect
to such notices and demands. The Company shall not, except with the prior
written consent of Parent, make any payment with respect to, or settle or offer
to settle, any such demands. Prior to the Effective Time, the Company shall
establish an escrow account with a financial institution and the Company shall
fund such escrow account with cash or cash equivalents in an amount sufficient
to make all payments to holders of Dissenting Shares. Such escrow account shall
survive the Merger. All payments to holders of Dissenting Shares shall be made
out of such escrow account, and no such payments shall be made or otherwise
funded by Parent.

corporate power and authority and all necessary governmental approvals to own,
lease and operate its properties and to carry on its business as it is now being

reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. The Company and each Company Subsidiary is duly
qualified or licensed to do business, and is in good standing (to the extent
applicable), in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing necessary, except for such failures to be so qualified or licensed
and in good standing that could not reasonably be expected to have, individually
or in the aggregate, a Company Material Adverse Effect.
 
    (b) Section 4.01 of the Company Disclosure Schedule sets forth, as of the
date of this Agreement, a true and complete list of each Company Subsidiary,
together with (i) the jurisdiction of incorporation or organization of each
Company Subsidiary and the percentage of each Company Subsidiary's outstanding

                                       12

or commitments of any character to which the Company is a party or by which the
Company is bound relating to the issued or unissued capital stock of the Company
or any Company Subsidiary or obligating the Company or any Company Subsidiary to
issue or sell any shares of capital stock of, or other equity interests in, the

another Company Subsidiary is free and clear of all security interests, liens,
claims, pledges, options, rights of first refusal, agreements, limitations on
the Company's or such other Company Subsidiary's voting rights, charges and
other encumbrances of any nature whatsoever, except where the failure to own
such shares free and clear could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. Except as
set forth in Section 4.03 of the Company Disclosure Schedule, there are no
material outstanding contractual obligations of the Company or any Company
Subsidiary to provide funds to, or make any material investment (in the form of
a loan, capital contribution or otherwise) in, any Company Subsidiary or any
other person.
 
    SECTION 4.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement,

the legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms.

performance by the Company of its obligations hereunder and the consummation of
the Merger will not, (i) conflict with or violate any provision of the articles
of incorporation or bylaws of the Company or any equivalent organizational
documents of any Company Subsidiary, (ii) assuming that all consents, approvals,
authorizations and permits described in Section 4.05(b) have been obtained and

conflict with or violate any Law applicable to the Company or any Company

of the Company Disclosure Schedule, result in any breach of or constitute a
default
 
                                       13

(or an event which with the giving of notice or lapse of time or both could
reasonably be expected to become a default) under, or give to others any right
of termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or other encumbrance on any property or asset of the Company
or any Company Subsidiary pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation, except, with respect to clauses (ii) and (iii), for any such
conflicts, violations, breaches, defaults or other occurrences which could not
reasonably be expected, individually or in the aggregate, (A) to have a Company
Material Adverse Effect or (B) to prevent or materially delay the performance by
the Company of its obligations pursuant to this Agreement or the consummation of
the Merger.
 
    (b) The execution and delivery of this Agreement by the Company do not, and
the performance by the Company of its obligations hereunder and the consummation
of the Merger will not, require any consent, approval, authorization or permit
of, or filing by the Company with or notification by the Company to, any
Governmental Entity, except (i) pursuant to applicable requirements of the
Exchange Act, the Securities Act, Blue Sky Laws, the rules and regulations of
the NYSE, state takeover laws, the premerger notification requirements of the
HSR Act, if any, the filing and recordation of the Articles of Merger as
required by the Business Corporation Act, and as set forth in Section 4.05(b) of
the Company Disclosure Schedule, and (ii) where failure to obtain such consents,
approvals, authorizations or permits, or to make such filings or notifications,
could not reasonably be expected, individually or in the aggregate, (A) to have
a Company Material Adverse Effect or (B) to prevent or materially delay the
performance by the Company of its obligations pursuant to this Agreement or the
consummation of the Merger.
 
    SECTION 4.06.  PERMITS; COMPLIANCE WITH LAWS.  (a) The Company and the
Company Subsidiaries are in possession of (i) all franchises, grants,
authorizations, licenses, establishment registrations, product listings,
permits, easements, variances, exceptions, consents, certificates,
identification and registration numbers, approvals and orders of any
Governmental Entity necessary for the Company or any Company Subsidiary to own,
lease and operate its properties or to produce, store, distribute and market its
products or otherwise to carry on its business as it is now being conducted and
(ii) agreements from all Federal, state, foreign and local governmental agencies
and accrediting and certifying organizations having jurisdiction over such
facility or facilities that are required to operate the facility or facilities
in the manner in which it or they are currently operated and receive
reimbursement for care provided to patients covered under the Federal Medicare
program ("MEDICARE"), any applicable state Medicaid program ("MEDICAID") or any
comparable foreign medical reimbursement program (collectively, the "COMPANY
PERMITS"), except where the failure to have, or the suspension or cancellation
of, any of the Company Permits could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect, and, as of
the date of this Agreement, no suspension or cancellation of any of the Company
Permits is pending or, to the knowledge of the Company, threatened, except where
the failure to have, or the suspension or cancellation of, any of the Company
Permits could not reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect. Without limiting the generality of
the foregoing, except as set forth in Section 4.06(a) of the Company Disclosure
Schedule, all of the Company's facilities are certified for participation or
enrollment in the Medicare program, have a current and valid provider contract
with the Medicare program and are in substantial compliance with the conditions
of participation of such programs. Neither the Company nor any Company
Subsidiary is in conflict with, or in default or violation of, (i) any Law
applicable to the Company or any Company Subsidiary or by which any property or
asset of the Company or any Company Subsidiary is bound or affected or (ii) any
Company Permits, except in the case of clauses (i) and (ii) for any such
conflicts, defaults or violations that could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. Neither the
Company nor any Company Subsidiary has received notice from the regulatory
authorities that enforce the statutory or regulatory provisions in respect of
either the Medicare or the Medicaid program of any pending or threatened
investigations or surveys, and no such investigations or surveys are pending or,
to the knowledge of the Company, threatened or imminent that could reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect. Section 4.06(a) of the Company
 
                                       14
<PAGE>
Disclosure Schedule sets forth, as of the date of this Agreement, all actions,
proceedings, investigations or surveys pending or, to the knowledge of the
Company, threatened against the Company or any Company Subsidiary that could
reasonably be expected to result in (i) the loss or revocation of a Company
Permit necessary to operate one or more facilities or for a facility to receive
reimbursement under the Medicare or Medicaid programs or (ii) the suspension or
cancellation of any other Company Permit, except any such Company Permit where
such suspension or cancellation could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect. Except as
set forth in Section 4.06(a) of the Company Disclosure Schedule, since June 30,
1996, neither the Company nor any Company Subsidiary has received from any
Governmental Entity any written notification with respect to possible conflicts,
defaults or violations of Laws, except for written notices relating to possible
conflicts, defaults or violations that could not reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect.
 
    (b) The Company and each Company Subsidiary, as appropriate, is an approved
participating provider in and under all third party payment programs from which
it receives revenues. No action or investigation is pending, or to the best of
its knowledge, threatened to suspend, limit, terminate, condition, or revoke the
status of the Company or any Company Subsidiary as a provider in any such
program, and neither the Company nor any Company Subsidiary has been provided
notice by any third party payor of its intention to suspend, limit, terminate,
revoke, condition or fail to renew in whole or in part or decrease the amounts
payable under any arrangement with the Company or such Company Subsidiary as a
provider, which action, investigation or proceeding would have, individually or
in the aggregate, a Company Material Adverse Effect.
 
    (c) Neither the Company nor any Company Subsidiary is delinquent with
respect to the filing of any claims, cost reports or annual filings required to
be filed to secure payments for services rendered by them under any third-party
payment program from which they receive or expect to receive revenues. Section
4.06(c) sets forth the date of the most recent such filing for each of the
Company's and the Company's Subsidiaries' facilities. Except as indicated in its
financial statements included in the Company Reports, the Company or each
Company Subsidiary, as applicable, has paid, or caused to be paid, all refunds,
discounts, adjustments, or amounts owing that have become due to such third
party payors pursuant to such claims, reports or filings, and neither the
Company nor any Company Subsidiary has any knowledge or notice of any material
changes required to be made to any cost reports, claims or filings made by it
for any period or of any deficiency in any such claim, report, or filing, except
for changes and deficiencies that in the aggregate would not have a Company
Material Adverse Effect.
 
    SECTION 4.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a) Except as disclosed
in Section 4.07 of the Company Disclosure Schedule, the Company has timely filed
all forms, reports, statements and documents required to be filed by it (A) with
the SEC and the NYSE since June 30, 1994 through the date of this Agreement
(collectively and as amended, the "COMPANY REPORTS") and (B) with any other
Governmental Entities, including, without limitation, state insurance and health
regulatory authorities. Each Company Report (i) was prepared in accordance with
the requirements of the Securities Act, the Exchange Act or the rules and
regulations of the NYSE, as the case may be, and (ii) did not at the time it was
filed contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements made therein, in the light of the circumstances under which they were
made, not misleading. Each form, report, statement and document referred to in
clause (B) of this paragraph was prepared in all material respects in accordance
with the requirements of applicable Law. Except as disclosed in Section 4.07 of
the Company Disclosure Schedule, no Company Subsidiary is subject to the
periodic reporting requirements of the Exchange Act or required to file any
form, report or other document with the SEC, the NYSE, any other stock exchange
or any other comparable Governmental Entity.
 
    (b) Each of the consolidated financial statements (including, in each case,
any notes thereto) contained in the Company Reports was prepared in accordance
with U.S. GAAP applied on a consistent
 
                                       15
<PAGE>
basis throughout the periods indicated (except as may be indicated in the notes
thereto) and each presented fairly, in all material respects, the consolidated
financial position of the Company and the consolidated Company Subsidiaries as
at the respective dates thereof and for the respective periods indicated
therein, except as otherwise noted therein (subject, in the case of unaudited
statements, to normal and recurring year-end adjustments which did not have and
could not reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect).
 
    (c) Except as and to the extent set forth or reserved against on the
consolidated balance sheet of the Company and the Company Subsidiaries as
reported in the Company Reports, including the notes thereto, none of the
Company or any Company Subsidiary has any liabilities or obligations of any
nature (whether accrued, absolute, contingent or otherwise) that would be
required to be reflected on a balance sheet or in notes thereto prepared in
accordance with U.S. GAAP, except for liabilities or obligations incurred in the
ordinary course of business consistent with past practice since June 30, 1996
that have not had and could not reasonably be expected to have, individually or
in the aggregate, a Company Material Adverse Effect.
 
    SECTION 4.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since June 30, 1996,
except as contemplated by or as disclosed in this Agreement, as set forth in
Section 4.08 of the Company Disclosure Schedule or as disclosed in any Company
Report filed since June 30, 1996, the Company and the Company Subsidiaries have
conducted their businesses only in the ordinary course consistent with past
practice and, since such date, there has not been (i) any Company Material
Adverse Effect, excluding any changes and effects resulting from changes in
economic, regulatory or political conditions or changes in conditions generally
applicable to the industries in which the Company and the Company Subsidiaries
are involved, (ii) any event that could reasonably be expected to prevent or
materially delay the performance of its obligations pursuant to this Agreement
and the consummation of the Merger by the Company, (iii) any material change by
the Company in its accounting methods, principles or practices, (iv) any
declaration, setting aside or payment of any dividend or distribution in respect
of the shares of Company Capital Stock or any redemption, purchase or other
acquisition of any of the Company's securities or (v) any increase in the
compensation or benefits or establishment of any bonus, insurance, severance,
deferred compensation, pension, retirement, profit sharing, stock option
(including, without limitation, the granting of stock options, stock
appreciation rights, performance awards or restricted stock awards), stock
purchase or other employee benefit plan, or any other increase in the
compensation payable or to become payable to any executive officers of the
Company or any Company Subsidiary except in the ordinary course of business
consistent with past practice.
 
    SECTION 4.09.  EMPLOYEE BENEFIT PLANS; LABOR MATTERS.  (a) Section 4.09(a)
of the Company Disclosure Schedule lists (i) all employee benefit plans (as
defined in Section 3(3) of ERISA) and all bonus, stock option, stock purchase,
restricted stock, incentive, deferred compensation, retiree medical or life
insurance, supplemental retirement, severance or other benefit plans, programs
or arrangements, and all employment, termination, severance or other contracts
or agreements, whether legally enforceable or not, to which the Company or any
Company Subsidiary is a party, with respect to which the Company or any Company
Subsidiary has any obligation or which are maintained, contributed to or
sponsored by the Company or any Company Subsidiary for the benefit of any
current or former employee, officer or director of the Company or any Company
Subsidiary, (ii) each employee benefit plan for which the Company or any Company
Subsidiary could incur liability under Section 4069 of ERISA in the event such
plan has been or were to be terminated, (iii) any plan in respect of which the
Company or any Company Subsidiary could incur liability under Section 4212(c) of
ERISA and (iv) any contracts, arrangements or understandings between the Seller
or any of its affiliates and any employee of the Company or of any Company
Subsidiary, including, without limitation, any contracts, arrangements or
understandings relating to the sale of the Company (collectively, the "COMPANY
BENEFIT PLANS"). With respect to each Company Benefit Plan, the Company has
delivered or made available to Parent a true, complete and correct copy of (i)
such Company Benefit Plan and the most recent summary plan description related
to such Company Benefit Plan, if a summary plan description is required
therefor, (ii) each trust agreement or other funding arrangement
 
                                       16
<PAGE>
relating to such Company Benefit Plan, (iii) the most recent annual report (Form
5500) filed with the IRS) with respect to such Company Benefit Plan, (iv) the
most recent actuarial report or financial statement relating to such Company
Benefit Plan and (v) the most recent determination letter issued by the IRS with
respect to such Company Benefit Plan, if it is qualified under Section 401(a) of
the Code. Except as disclosed on Section 4.09(a) of the Company Disclosure
Schedule, there are no other employee benefit plans, programs, arrangements or
agreements, whether formal or informal, whether in writing or not, to which the
Company or any Company Subsidiary is a party, with respect to which the Company
or any Company Subsidiary has any obligation or which are maintained,
contributed to or sponsored by the Company or any Company Subsidiary for the
benefit of any current or former employee, officer or director of the Company or
any Company Subsidiary. Neither the Company nor any Company Subsidiary has any
express or implied commitment, whether legally enforceable or not, (i) to
create, incur liability with respect to or cause to exist any other employee
benefit plan, program or arrangement, (ii) to enter into any contract or
agreement to provide compensation or benefits to any individual or (iii) to
modify, change or terminate any Company Benefit Plan, other than with respect to
a modification, change or termination required by ERISA or the Code.
 
    (b) None of the Company Benefit Plans is a multiemployer plan (within the
meaning of Section 3(37) or 4001(a)(3) of ERISA) (a "MULTIEMPLOYER PLAN") or a
single employer pension plan (within the meaning of Section 4001(a)(15) of
ERISA) for which the Company or any Company Subsidiary could incur liability
under Section 4063 or 4064 of ERISA (a "MULTIPLE EMPLOYER PLAN"). None of the
Company Benefit Plans provides for or promises retiree medical, disability or
life insurance benefits to any current or former employee, officer or director
of the Company or any Company Subsidiary.
 
    (c) Each Company Benefit Plan has been administered in all material respects
in accordance with its terms and all contributions required to be made under the
terms of any of the Company Benefit Plans as of the date of this Agreement have
been timely made or have been reflected on the most recent consolidated balance
sheet filed or incorporated by reference in the Company Reports prior to the
date of this Agreement. Except as set forth in Section 4.09(c) of the Company
Disclosure Schedule, with respect to the Company Benefit Plans, no event has
occurred and, to the knowledge of the Company, there exists no condition or set
of circumstances in connection with which the Company or any Company Subsidiary
could be subject to any liability under the terms of such Company Benefit Plans,
ERISA, the Code or any other applicable Law which could reasonably be expected
to have, individually or in the aggregate, a Company Material Adverse Effect. No
legal action, suit or claim is pending or threatened with respect to any Company
Benefit Plan (other than claims for benefits in the ordinary course).
 
    (d) The Company on behalf of itself and all of the Company Subsidiaries
hereby represents that, other than as disclosed in Section 4.09(d) of the

Parent, to the knowledge of the Company, there are no existing facts or
circumstances that could reasonably be expected to result in such a suit, claim,
action, proceeding or investigation. Except as disclosed to Parent, the Company
is not aware of any facts or circumstances which could reasonably be expected to
result in the denial of insurance coverage under policies issued to the Company

to which the Company is maintaining reserves to the extent currently required in
all material respects adequate for their payment; (b) neither the IRS nor any
other taxing authority or agency is now asserting or, to the best of the

of Section 280G of the Code, determined without regard to Section 280G(b)(4) of
the Code; (i) neither the Company nor any of the Company Subsidiaries owns any

nor any of the Company Subsidiaries has an "excess loss account" for purposes of

    Parent and Merger Sub hereby jointly and severally represent and warrant to

Sub and each other subsidiary of Parent (the "PARENT SUBSIDIARIES") has been

organization, as the case may be, and has the requisite corporate power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as it is now being conducted, except

such power, authority and governmental approvals could not reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect. Parent, Merger Sub and each other Parent Subsidiary is duly qualified or
licensed to do business, and is in good standing (to the extent applicable), in
each jurisdiction where the character of the properties owned, leased or
operated by it or the nature of its business makes such qualification or
licensing necessary, except for such failures to be so qualified or licensed and
in good standing that could not reasonably be expected to have, individually or
in the aggregate, a Parent Material Adverse Effect.
 
    (b) Section 5.01 of the Parent Disclosure Schedule sets forth, as of the
date of this Agreement, a true and complete list of each Parent Subsidiary,
together with (i) the jurisdiction of incorporation or organization of each
Parent Subsidiary and the percentage of each Parent Subsidiary's outstanding

Subsidiary and (ii) an indication of whether each Parent Subsidiary is a
"Significant Subsidiary" as defined in Regulation S-X under the Exchange Act.
Except as set forth in Section 5.01 of the Parent Disclosure Schedule, neither
Parent nor any Parent Subsidiary owns an equity interest in any partnership or
joint venture arrangement or other business entity that is material to the
financial condition, results of operations, business or prospects of Parent and
the Parent Subsidiaries, taken as a whole.
 
    SECTION 5.02.  CERTIFICATE OF INCORPORATION AND BYLAWS.  The copies of
Parent's certificate of incorporation and bylaws that are incorporated by
reference as exhibits to Parent's Annual Report on Form 10-K for the fiscal year
ended December 31, 1995 (the "PARENT 1995 10-K") are true, complete and correct
copies thereof. Parent has heretofore furnished the Company with true, complete
and correct copies of the articles of incorporation and bylaws of Merger Sub.
Such certificate or articles of incorporation, as the case may be, and bylaws
are in full force and effect. Neither Parent nor Merger Sub is in violation of
any of the provisions of its certificate or articles of incorporation, as the
case may be, or bylaws.
 
    SECTION 5.03.  CAPITALIZATION.  The authorized capital stock of Parent
consists of 100,000,000 shares of Parent Common Stock and 5,000,000 shares of
preferred stock, 1,000,000 of which have been designated as Parent Preferred

granted under the Parent Stock Plans, (vi) 500,000 shares of Parent Common Stock
are reserved for future issuance pursuant to outstanding warrants to purchase

for issuance upon conversion of Parent's 6 1/2%
 
                                       22
<PAGE>
Convertible Subordinated Debentures due 2003, (ix) no shares of Parent Preferred
Stock are issued and outstanding and (x) 1,000,000 shares of Parent Preferred
Stock are reserved for future issuance pursuant to the Parent Rights. At or
prior to the Effective Time, Parent shall have designated 450,000 (less the
number of shares of Series F Preferred that are converted after the date hereof)
shares of preferred stock as Parent New Preferred and reserved a sufficient
number of shares of Parent Common Stock for issuance upon conversion of the
Parent New Preferred. As of the date hereof, there are no shares of preferred
stock of Parent issued and outstanding. Except for the shares of Parent Common
Stock issuable pursuant to the Parent Stock Plans, pursuant to the Parent Rights
or pursuant to agreements or arrangements described in Section 5.03 of the
Parent Disclosure Schedule, there are no options, warrants or other rights,
agreements, arrangements or commitments of any character to which Parent is a
party or by which Parent is bound relating to the issued or unissued capital

validly issued, fully paid and nonassessable. Each outstanding share of capital
stock of each Parent Subsidiary is duly authorized, validly issued, fully paid
and nonassessable and each such share owned by Parent or another Parent
Subsidiary is free and clear of all security interests, liens, claims, pledges,
options, rights of first refusal, agreements, limitations on Parent's or such
other Parent Subsidiary's voting rights, charges and other encumbrances of any
nature whatsoever, except where the failure to own such shares free and clear
could not reasonably be expected to have, individually or in the aggregate, a
Parent Material Adverse Effect. Except as set forth in Section 5.03 of the
Parent Disclosure Schedule, there are no material outstanding contractual
obligations of Parent, Merger Sub or any other Parent Subsidiary to provide
funds to, or make any material investment (in the form of a loan, capital
contribution or otherwise) in, any Parent Subsidiary or any other person.
 
    SECTION 5.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  Parent and Merger Sub

Agreement, to perform their respective obligations hereunder and to consummate
the transactions contemplated hereby. The execution and delivery of this
Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub
of the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action, and no other corporate proceedings on the part
of Parent or Merger Sub are necessary to authorize this Agreement or to
consummate such transactions (other than the approval of this Agreement and the
Merger by the holders of a majority of the outstanding shares of Parent Common
Stock entitled to vote with respect thereto at the Parent Stockholders' Meeting,
if required, and the filing and recordation of the Articles of Merger as
required by the Business Corporation Act). This Agreement has been duly executed
and delivered by Parent and Merger Sub and, assuming the due authorization,

execution and delivery of this Agreement by Parent and Merger Sub do not, and
the performance by Parent and Merger Sub of their obligations hereunder and the
consummation of the Merger will not, (i) conflict with or violate any provision
of the certificate or articles of incorporation, as the case may be, or bylaws
of Parent or Merger Sub or any equivalent organizational documents of any other
Parent Subsidiary, (ii) assuming that all consents, approvals, authorizations
and permits described in Section 5.05(b) have been obtained and all filings and
notifications described in Section 5.05(b) have been made, conflict with or
violate any Law applicable to Parent or any other Parent Subsidiary or by which
any property or asset of Parent, Merger Sub or any other Parent Subsidiary is
bound or affected or (iii) except as set forth in Section 5.05(a) of the Parent
Disclosure Schedule, result in any breach of or constitute a default (or an
event which with the giving of notice or lapse of time or both could reasonably
be expected to become a default) under, or give to others any right of
termination, amendment, acceleration or cancellation of, or result in the
creation of a
 
                                       23
<PAGE>
lien or other encumbrance on any property or asset of Parent, Merger Sub or any
other Parent Subsidiary pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation, except, with respect to clauses (ii) and (iii), for any such
conflicts, violations, breaches, defaults or other occurrences which could not
reasonably be expected, individually or in the aggregate, (A) to have a Parent
Material Adverse Effect or (B) to prevent or materially delay the performance by
Parent or Merger Sub of its obligations pursuant to this Agreement or the
consummation of the Merger.
 
    (b) The execution and delivery of this Agreement by Parent and Merger Sub do
not, and the performance by Parent and Merger Sub of their respective
obligations hereunder and the consummation of the Merger will not, require any
consent, approval, authorization or permit of, or filing by Parent or Merger Sub
with or notification by Parent or Merger Sub to, any Governmental Entity, except
(i) pursuant to applicable requirements of the Exchange Act, the Securities Act,
Blue Sky Laws, the rules and regulations of the NYSE, state takeover laws, the
premerger notification requirements of the HSR Act, if any, and the filing and
recordation of the Articles of Merger as required by the Business Corporation
Act and (ii) where failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, could not reasonably be
expected, individually or in the aggregate, (A) to have a Parent Material
Adverse Effect or (B) to prevent or materially delay the performance by Parent
or Merger Sub of its obligations pursuant to this Agreement or the consummation
of the Merger.
 
    SECTION 5.06.  PERMITS; COMPLIANCE WITH LAWS.  (a) Parent, Merger Sub and
each other Parent Subsidiary is in possession of (i) all franchises, grants,
authorizations, licenses, establishment registrations, product listings,

medical reimbursement program (collectively, the "PARENT PERMITS"), except where
the failure to have, or the suspension or cancellation of, any of the Parent
Permits could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect, and, as of the date of this
Agreement, no suspension or cancellation of any of the Parent Permits is pending
or, to the knowledge of Parent, threatened, except where the failure to have, or
the suspension or cancellation of, any of the Parent Permits could not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Without limiting the generality of the foregoing,
except as set forth in Section 5.06(a) of the Parent Disclosure Schedule, all of
Parent's facilities are certified for participation or enrollment in the
Medicare program, have a current and valid provider contract with the Medicare
program and are in substantial compliance with the conditions of participation
of such programs. None of Parent, Merger Sub or any other Parent Subsidiary is
in conflict with, or in default or violation of, (i) any Law applicable to
Parent, Merger Sub or any other Parent Subsidiary or by which any property or
asset of Parent, Merger Sub or any other Parent Subsidiary is bound or affected
or (ii) any Parent Permits, except in the case of clauses (i) and (ii) for any
such conflicts, defaults or violations that could not reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect.
Neither Purchaser nor any Purchaser Subsidiary has received notice from the
regulatory authorities that enforce the statutory or regulatory provisions in
respect of either the Medicare or the Medicaid program of any pending or
threatened investigations or surveys, and no such investigations or surveys are
pending or, to the knowledge of Parent, threatened or imminent that could
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Section 5.06(a) of the Parent Disclosure Schedule sets
forth, as of the date of this Agreement, all actions, proceedings,
investigations or surveys pending or, to the knowledge of Parent, threatened
against Parent or any Parent Subsidiary that could reasonably be expected
 
                                       24
<PAGE>
to result in (i) the loss or revocation of a Parent Permit necessary to operate
one or more facilities or for a facility to receive reimbursement under the
Medicare or Medicaid program or (ii) the suspension or cancellation of any other
Parent Permit, except any such Parent Permit where such suspension or
cancellation could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. Except as set forth in Section
5.06(a) of the Parent Disclosure Schedule, since December 31, 1995, neither
Parent nor any Parent Subsidiary has received from any Governmental Entity any
written notification with respect to possible conflicts, defaults or violations
of Laws, except for written notices relating to possible conflicts, defaults or
violations that could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect.
 
    (b) Parent and each Parent Subsidiary, as appropriate, is an approved
participating provider in and under all third party payment programs from which
it receives revenues. No action or investigation is pending, or to the best of
its knowledge, threatened to suspend, limit, terminate, condition, or revoke the
status of Parent or any Parent Subsidiary as a provider in any such program, and
neither Parent nor any Parent Subsidiary has been provided notice by any third
party payor of its intention to suspend, limit, terminate, revoke, condition or
fail to renew in whole or in part or decrease the amounts payable under any
arrangement with Parent or such Parent Subsidiary as a provider, which action,
investigation or proceeding would have, individually or in the aggregate, a
Parent Material Adverse Effect.
 
    (c) Parent and each Parent Subsidiary have filed on a timely basis all
claims, cost reports or annual filings required to be filed to secure payments
for services rendered by them under any third-party payment program from which
they receive or expect to receive revenues, except where the failure to file
such claim, report or other filing would not have, individually or in the
aggregate, a Parent Material Adverse Effect. Except as indicated in its
financial statements included in the Parent Reports, Parent or each Parent
Subsidiary, as applicable, has paid, or caused to be paid, all refunds,
discounts, adjustments, or amounts owing that have become due to such third
party payors pursuant to such claims, reports or filings, and neither Parent nor
any Parent Subsidiary has any knowledge or notice of any material changes
required to made to any cost reports, claims, or filings made by it for any
period or of any deficiency in such claim, report, or filing, except for changes
and deficiencies that in the aggregate would not have a Parent Material Adverse
Effect.
 
    SECTION 5.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a) Parent has timely
filed all forms, reports, statements and documents required to be filed by it
(A) with the SEC and the NYSE since December 31, 1994 through the date of this
Agreement (collectively and as amended, the "PARENT REPORTS") and (B) with any
other Governmental Entities, including, without limitation, state insurance and
health regulatory authorities. Except as is provided in the Parent Reports or as
disclosed in Section 5.07(a) of the Parent Disclosure Schedule, each Parent
Report (i) was prepared in accordance with the requirements of the Securities
Act, the Exchange Act or the NYSE, as the case may be, and (ii) did not at the
time it was filed contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements made therein, in the light of the circumstances under which
they were made, not misleading. Each form, report, statement and document
referred to in clause (B) of this paragraph was prepared in all material
respects in accordance with the requirements of applicable Law. Except as
disclosed in Section 5.07(a) of the Parent Disclosure Schedule, no Parent
Subsidiary is subject to the periodic reporting requirements of the Exchange Act
or required to file any form, report or other document with the SEC, the NYSE,
any other stock exchange or any other comparable Governmental Entity.
 
    (b) Except as is provided in the Parent Reports or in Section 5.07(b) of the
Parent Disclosure Schedule, each of the consolidated financial statements
(including, in each case, any notes thereto) contained in the Parent Reports was
prepared in accordance with U.S. GAAP applied on a consistent basis throughout
the periods indicated (except as may be indicated in the notes thereto) and each
presented fairly, in all material respects, the consolidated financial position
of Parent and the consolidated Parent Subsidiaries as at the respective dates
thereof and for the respective periods indicated therein, except as
 
                                       25
<PAGE>
otherwise noted therein (subject, in the case of unaudited statements, to normal
and recurring year-end adjustments which were not and are not expected,
individually or in the aggregate, to have a Parent Material Adverse Effect).
 
    (c) Except as and to the extent set forth or reserved against on the
consolidated balance sheet of Parent and its Subsidiaries as reported in the
Parent Reports, including the notes thereto, or as disclosed in Section 5.07(c)
of the Parent Disclosure Schedule, none of Parent or any Parent Subsidiary has
any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) that would be required to be reflected on a balance
sheet or in notes thereto prepared in accordance with U.S. GAAP, except for
liabilities or obligations incurred in the ordinary course of business
consistent with past practice since December 31, 1995 that have not had and
could not reasonably be expected to have, individually or in the aggregate, a
Parent Material Adverse Effect.
 
    SECTION 5.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since December 31,
1995, except as contemplated by or as disclosed in this Agreement, as set forth
in Section 5.08 of the Parent Disclosure Schedule or as disclosed in any Parent
Report filed since December 31, 1995, Parent and the Parent Subsidiaries have
conducted their businesses only in the ordinary course consistent with past
practice and, since such date, there has not been (i) any Parent Material
Adverse Effect, excluding any changes and effects resulting from changes in
economic, regulatory or political conditions or changes in conditions generally
applicable to the industries in which Parent and the Parent Subsidiaries are
involved, (ii) any event that could reasonably be expected to prevent or
materially delay the performance of its obligations pursuant to this Agreement
and the consummation of the Merger by Merger Sub, (iii) any material change by
Parent in its accounting methods, principles or practices or (iv) any
declaration, setting aside or payment of any dividend or distribution in respect
of the shares of Parent Common Stock or any redemption, purchase or other
acquisition of any of Parent's securities.
 
    SECTION 5.09.  EMPLOYEE BENEFIT PLANS; LABOR MATTERS.  (a) With respect to
each employee benefit plan, program, arrangement and contract (including,
without limitation, any "employee benefit plan", as defined in Section 3(3) of
ERISA) maintained or contributed to by Parent or any Parent Subsidiary, or with
respect to which Parent or any Parent Subsidiary could incur liability under
Section 4069, 4212(c) or 4204 of ERISA (the "PARENT BENEFIT PLANS"), Parent has
delivered or made available to the Company a true, complete and correct copy of
(i) such Parent Benefit Plan and the most recent summary plan description
related to such Parent Benefit Plan, if a summary plan description is required
therefor, (ii) each trust agreement or other funding arrangement relating to
such Parent Benefit Plan, (iii) the most recent annual report (Form 5500) filed
with the IRS with respect to such Parent Benefit Plan, (iv) the most recent

in accordance with its terms and all contributions required to be made under the
terms of any of the Parent Benefit Plans as of the date of this Agreement have
been timely made or have been reflected on the most recent consolidated balance
sheet filed or incorporated by reference in the Parent Reports prior to the date
of this Agreement. With respect to the Parent Benefit Plans, no event has
occurred and, to the knowledge of Parent, there exists no condition or set of
circumstances in connection with which Parent or any Parent Subsidiary could be
subject to any liability under the terms of such Parent Benefit Plans, ERISA,
the Code or any other applicable Law which could reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect.
 
    (c) Except as set forth in Section 5.09(c) of the Parent Disclosure
Schedule, neither Parent nor any Parent Subsidiary is a party to any collective
bargaining or other labor union contract applicable to persons employed by
Parent or any Parent Subsidiary and no collective bargaining agreement is being
negotiated by Parent or any Parent Subsidiary. As of the date of this Agreement,
there is no labor dispute, strike or
 
                                       26
<PAGE>
work stoppage against Parent or any Parent Subsidiary pending or, to the
knowledge of Parent, threatened which may interfere with the respective business
activities of Parent or any Parent Subsidiary, except where such dispute, strike
or work stoppage could not reasonably be expected to have, individually or in
the aggregate, a Parent Material Adverse Effect. As of the date of this
Agreement, to the knowledge of Parent, none of Parent, any Parent Subsidiary, or
any of their respective representatives or employees has committed any unfair
labor practice in connection with the operation of the respective businesses of
Parent or any Parent Subsidiary, and there is no charge or complaint against
Parent or any Parent Subsidiary by the National Labor Relations Board or any
comparable Governmental Entity pending or threatened in writing, except where
such unfair labor practice, charge or complaint could not reasonably be expected
to have, individually or in the aggregate, a Parent Material Adverse Effect.
 
    SECTION 5.10.  ACCOUNTING AND CERTAIN TAX MATTERS.  Except as disclosed in
the Parent Reports or in Section 5.10 of the Parent Disclosure Schedule, neither
Parent nor, to the knowledge of Parent, any of its affiliates has taken or
agreed to take any action (other than actions contemplated by this Agreement)
that could reasonably be expected to prevent the Merger from qualifying for
"pooling of interests" accounting treatment under applicable United States
accounting rules, including, without limitation, applicable SEC accounting
standards, or could reasonably be expected to prevent the Merger from
constituting a transaction qualifying under Section 368 of the Code. Parent is
not aware of any agreement, plan or other circumstances that could reasonably be
expected to prevent the Merger from so qualifying under Section 368 of the Code.
 
    SECTION 5.11.  CONTRACTS; DEBT INSTRUMENTS.  Except as disclosed in the
Parent Reports or in Section 5.11 of the Parent Disclosure Schedule, there is no
contract or agreement that is material to the business, financial condition or
results of operations of Parent and the Parent Subsidiaries taken as a whole
(each, a "PARENT MATERIAL CONTRACT"). Except as disclosed in the Parent Reports,
neither Parent nor any Parent Subsidiary is in violation of or in default under
(nor does there exist any condition which with the passage of time or the giving
of notice could reasonably be expected to cause such a violation of or default
under) any loan or credit agreement, note, bond, mortgage, indenture or lease,
or any other contract, license, agreement, arrangement or understanding to which
it is a party or by which it or any of its properties or assets is bound, except
for violations or defaults that could not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect. Set forth in
Section 5.11 of the Parent Disclosure Schedule is a description of any material
changes to the amount and terms of the indebtedness of Parent and its
subsidiaries as described in the notes to the financial statements incorporated

could reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect, and, except as disclosed to the Company, to the
knowledge of Parent, there are no existing facts or circumstances that could
reasonably be expected to result in such a suit, claim, action, proceeding or
investigation. Except as disclosed to the Company, Parent is not aware of any
facts or circumstances which could reasonably be expected to result in the
denial of insurance coverage under policies issued to Parent and the Parent
Subsidiaries in respect of such suits, claims, actions, proceedings and
investigations, except in any case as could not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect. Except as
disclosed in the Parent Reports, neither Parent nor any Parent Subsidiary is
subject to any outstanding order, writ, injunction or decree which could
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect.
 
    SECTION 5.13.  ENVIRONMENTAL MATTERS.  Except as disclosed in the Parent

aggregate, a Parent Material Adverse Effect, (i) Parent and the Parent

past noncompliance of Parent or any Parent Subsidiary with Environmental Laws or
Environmental

expected to have, individually or in the aggregate, a Parent Material Adverse
Effect, Parent and the Parent Subsidiaries own or possess adequate licenses or
other valid rights to use all patents, patent rights, trademarks, trademark
rights, trade names, trade dress, trade name rights, copyrights, service marks,
trade secrets, applications for trademarks and for service marks, know-how and
other proprietary rights and information used or held for use in connection with
the respective businesses of Parent and the Parent Subsidiaries as currently
conducted, and Parent is unaware of any assertion or claim challenging the
validity of any of the foregoing. Section 5.14 of the Parent Disclosure Schedule
lists all material licenses, sublicenses and other agreements to which Parent or
any Parent Subsidiary is a party and pursuant to which (i) any third party is
authorized to use any intellectual property right of Parent or any Parent
Subsidiary and (ii) Parent or any Parent Subsidiary is authorized to use any
intellectual property rights (other than pursuant to shrink-wrap licenses and
software licenses) of a third party, and includes the identity of all parties

provisions, if any, therein and the term thereof. Except as set forth in Section
5.14 of the Parent Disclosure Schedule, the conduct of the respective businesses
of Parent and the Parent Subsidiaries as currently conducted does not conflict
in any way with any patent, patent right, license, trademark, trademark right,
trade dress, trade name, trade name right, service mark or copyright of any
third party that could reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. To the knowledge of Parent, there
are no infringements of any proprietary rights owned by or licensed by or to
Parent or any Parent Subsidiary that could reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect.
 
    SECTION 5.15.  TAXES.  Except as set forth in Section 5.15 of the Parent
Disclosure Schedule and except for such matters that could not reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect, (i) Parent, Merger Sub and each other Parent Subsidiary has timely filed
or shall timely file all returns and reports required to be filed by it with any
taxing authority with respect to Taxes for any period ending on or before the
Effective Time, taking into account any extension of time to file granted to or

significant business relations in order to preserve substantially intact its
business organization. By way of amplification and not limitation, except as set

contemplated by any other provision of this Agreement, neither the Company nor
any Company Subsidiary shall, between the date of this Agreement and the
Effective Time, directly or indirectly, do, or agree to do, any of the following

    in any of the conditions to the Merger set forth herein not being satisfied.

effect the consummation of the Merger.
 
    SECTION 6.05.  ACCESS TO INFORMATION; CONFIDENTIALITY.  (a) Except as
required pursuant to any confidentiality agreement or similar agreement or
arrangement to which Parent or the Company or any of the Parent Subsidiaries or
the Company Subsidiaries is a party or pursuant to applicable Law or the
regulations or requirements of any stock exchange or other regulatory
organization with whose rules a party hereto is required to comply, from the

shall cause the Parent Subsidiaries and the zpCompany Subsidiaries,
respectively, to) (i) provide to the other (and its officers, directors,
employees, accountants, consultants, legal counsel, agents and other
representatives (collectively, "REPRESENTATIVES")) access at reasonable times
upon prior notice to its and its subsidiaries' officers, employees, agents,
properties, offices and other facilities and to the books and records thereof,
and (ii) furnish promptly such information concerning its and its subsidiaries'
business, properties, contracts, assets, liabilities and personnel as the other
party or its Representatives may reasonably request. No investigation conducted
pursuant to this Section 6.05 shall affect or be deemed to modify any

    (b) The parties hereto shall comply with, and shall cause their respective
Representatives to comply with, all of their respective obligations under the
Confidentiality Agreements with respect to the information disclosed pursuant to
this Section 6.05.
 
    SECTION 6.06.  NO SOLICITATION OF TRANSACTIONS.  The Company shall not,
directly or indirectly, and shall instruct its officers, directors, employees,
subsidiaries, agents or advisors or other representatives (including, without
limitation, any investment banker, attorney or accountant retained by it), not
to, directly or indirectly, solicit, initiate or knowingly encourage (including
by way of furnishing nonpublic information), or take any other action knowingly
to facilitate, any inquiries or the making of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders) that constitutes,
or may reasonably be expected to lead to, any Competing Transaction, or enter
into or maintain or continue discussions or negotiate with any person in
furtherance of such inquiries or to obtain a Competing Transaction, or agree to
or endorse any Competing Transaction, or authorize or permit any of the
officers, directors or employees of the Company or any Company Subsidiary, or
any investment banker, financial advisor, attorney, accountant or other
representative retained by the Company or any Company Subsidiary, to take any
such action; PROVIDED, HOWEVER, that nothing contained in this Section 6.06
shall prohibit the board of directors of the Company from (i) complying with
Rule 14e-2 promulgated under the Exchange Act with regard to a tender or
exchange offer not made in violation of this Section 6.06 or (ii) with regard
 
                                       32
<PAGE>
to such an offer, after receiving the advice of outside counsel to the effect
that the board of directors of the Company is required to do so in order to
discharge properly its fiduciary duties, considering, negotiating and approving
and recommending to the shareholders of the Company an unsolicited bona fide
written acquisition proposal which (A) was not received in violation of this
Section 6.06, (B) if executed or consummated would be a Competing Transaction,
(C) is not subject to financing and (D) the board of directors of the Company
determines in good faith, after receipt of an opinion of its financial advisors
to such effect, would result in a transaction more favorable to the Company's
stockholders, than the transaction contemplated by this Agreement (any such
acquisition proposal, a "SUPERIOR PROPOSAL"). The Company shall notify Parent
promptly, and in no event later than one day after receipt, if any proposal or
offer, or any inquiry or contact with any person with respect thereto, regarding
a Competing Transaction is made. The Company immediately shall cease and cause
to be terminated all existing discussions or negotiations with any parties
conducted heretofore with respect to a Competing Transaction. The Company shall
not release any third party from, or waive any provision of, any confidentiality
or standstill agreement to which it is a party. The Company shall use its best
efforts to ensure that its officers, directors, employees, subsidiaries, agents
and advisors or other representatives (including, without limitation, any
investment banker, attorney or accountant retained by it) are aware of the
restrictions described in this Section 6.06.
 
    SECTION 6.07.  POOLING.  From and after the date of this Agreement, none of
the parties hereto, or any of their respective controlled affiliates, shall
knowingly take or fail to take any action, other than actions which such party
is required to take or abstain from taking pursuant to this Agreement, which
action or failure to act could reasonably be expected to jeopardize the
treatment of the Merger as a "pooling of interests" for accounting purposes.
From and after the date of this Agreement, each of the parties hereto shall take
all reasonable actions necessary to cause the Merger to be characterized as a
"pooling of interests" for accounting purposes.
 
    SECTION 6.08.  LETTERS OF ACCOUNTANTS.  At the written request of Parent,
each of the Company and Parent shall use all reasonable efforts to cause to be
delivered to the other "comfort" letters of each of Coopers & Lybrand L.L.P. and
BDO Seidman, LLP and Arthur Andersen LLP, respectively, each such letter dated
and delivered as of the date the Registration Statement shall have become
effective and as of the Effective Time, and addressed to Parent and the Company,
respectively, in form and substance reasonably satisfactory to the recipient
thereof and reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with mergers such as the Merger
contemplated hereby.
 
    SECTION 6.09.  PLAN OF REORGANIZATION.  This Agreement is intended to
constitute a "plan of reorganization" within the meaning of Section 1.368-2(g)
of the income tax regulations promulgated under the Code. From and after the
date of this Agreement, each party hereto shall use all reasonable efforts to
cause the Merger to qualify, and shall not, without the prior written consent of
the other parties hereto, knowingly take any actions or cause any actions to be
taken which could reasonably be expected to prevent the Merger from qualifying
as a reorganization under the provisions of Section 368 of the Code. In the
event that the Merger shall fail to qualify as a reorganization under the
provisions of Section 368 of the Code, then the parties hereto agree to
negotiate in good faith to restructure the Merger in order that it shall qualify
as tax-free transaction under the Code. Following the Effective Time, and
consistent with any such consent, neither the Surviving Corporation nor Parent
nor any of their respective affiliates knowingly and voluntarily shall take any
action or cause any action to be taken which could reasonably be expected to
cause the Merger to fail to qualify as a reorganization under Section 368 of the
Code.
 
    SECTION 6.10.  SUBSEQUENT FINANCIAL STATEMENTS.  Prior to the Effective
Time, each of the Company and Parent (i) shall consult with the other prior to
making publicly available its financial results for any period and (ii) shall

SEC, each Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current
Report on Form 8-K required
 
                                       33
<PAGE>
to be filed by such party under the Exchange Act and shall promptly deliver to
the other copies of each such report filed with the SEC.
 
    SECTION 6.11.  CONTROL OF OPERATIONS.  Nothing contained in this Agreement
shall give Parent, directly or indirectly, the right to control or direct the
operations of the Company and the Company Subsidiaries prior to the Effective
Time. Prior to the Effective Time, each of Parent and the Company shall
exercise, consistent with the terms and conditions of this Agreement, complete
control and supervision over its respective operations.
 
    SECTION 6.12.  FURTHER ACTION; CONSENTS; FILINGS.  (a) Upon the terms and
subject to the conditions hereof, each of the parties hereto shall use all
reasonable efforts to (i) take, or cause to be taken, all appropriate action,
and do, or cause to be done, all things necessary, proper or advisable under
applicable Law or otherwise to consummate and make effective the Merger, (ii)
obtain from Governmental Entities any consents, licenses, permits, waivers,
approvals, authorizations or orders required to be obtained or made by Parent,
Merger Sub, the Company or the Surviving Corporation or any of their respective
subsidiaries in connection with the authorization, execution and delivery of
this Agreement and the consummation of the Merger and (iii) make all necessary
filings, and thereafter make any other required or appropriate submissions, with
respect to this Agreement and the Merger required under (A) the rules and
regulations of the NYSE, (B) the Securities Act, the Exchange Act and any other
applicable Federal or state securities Laws, (C) the HSR Act, if any, and (D)
any other applicable Law. The parties hereto shall cooperate and consult with
each other in connection with the making of all such filings, including by
providing copies of all such documents to the nonfiling parties and their
advisors prior to filing, and none of the parties shall file any such document
if any of the other parties shall have reasonably objected to the filing of such
document. No party shall consent to any voluntary extension of any statutory
deadline or waiting period or to any voluntary delay of the consummation of the
Merger at the behest of any Governmental Entity without the consent and
agreement of the other parties hereto, which consent shall not be unreasonably
withheld or delayed.
 
    (b) Each of the parties hereto shall promptly give (or cause their
respective subsidiaries to give) any notices regarding the Merger, this
Agreement or the transactions contemplated hereby or thereby to third parties
required under applicable Law or by any contract, license, lease or other
agreement to which it or any of its subsidiaries is bound, and use, and cause
its subsidiaries to use, all reasonable efforts to obtain any third party
consents required under any such contract, license, lease or other agreement in
connection with the consummation of the Merger or the other transactions
contemplated by this Agreement.
 
    (c) The Company shall use its best efforts to obtain the Company Fairness
Opinion as promptly as practicable.

outstanding Company Stock Option, whether vested or unvested. Unless otherwise
elected by Parent prior to the Effective Time, Parent shall make such assumption
in such manner that Parent (i) is a corporation "assuming a stock option in a
transaction to which Section 424(a) applies" within the meaning of Section 424

after the Effective Time, all references to the Company in the Company Stock
Plans and the applicable Company Stock Option agreements shall be deemed to
refer to Parent, which shall have assumed the Company Stock Plans as of
 
                                       37
<PAGE>
the Effective Time by virtue of this Agreement and without any further action on
the part of the Company or Parent. Each Company Stock Option so assumed by
Parent under this Agreement shall continue to have, and be subject to, the same
terms and conditions set forth in the applicable Company Stock Plan and the
applicable Company Stock Option as in effect immediately prior to the Effective

reasonable efforts to ensure that Company Stock Options intended to qualify as
incentive stock options under Section 422 of the Code prior to the Effective
Time continue to so qualify after the Effective Time.
 
    (b) With respect to the Company Stock Plans, Parent shall take all corporate
action necessary or appropriate to, as soon as practicable after the Effective

cause each of its or the Company Subsidiaries' management contracts with
unrelated parties, including, without limitation, those disclosed in Section
7.11(b) of the Company Disclosure Schedule, to be amended at or prior to the

                 STOCKHOLDERS STOCK OPTION AND PROXY AGREEMENT
 
    STOCKHOLDERS STOCK OPTION AND PROXY AGREEMENT, dated as of February 17,
1997, among SUN HEALTHCARE GROUP INC., a Delaware corporation ("PARENT"), and
each other person and entity listed on the signature pages hereof (each, a
"STOCKHOLDER").
 
    WHEREAS, as of the date hereof each Stockholder owns (either beneficially or
of record) the number of shares of common stock, par value $0.0001 per share
("COMPANY COMMON STOCK"), Series AA Redeemable Convertible Preferred Stock ("AA
PREFERRED"), and Series F Convertible Preferred Stock ("F PREFERRED" and,
together with the Company Common Stock and AA Preferred, the "COMPANY CAPITAL
STOCK"), of Retirement Care Associates, Inc., a Colorado corporation (the
"COMPANY"), set forth opposite such Stockholder's name on Exhibit A hereto (all
such shares of Company Capital Stock owned by the Stockholders and any shares of
Company Capital Stock hereafter acquired by the Stockholders prior to the
termination of this Agreement being referred to herein as the "SHARES");
 
    WHEREAS, Parent and the Company propose to enter into an Agreement and Plan
of Merger and Reorganization, dated as of the date hereof (as the same may be
amended from time to time, the "MERGER AGREEMENT"; capitalized terms not
otherwise defined herein being herein with the meanings ascribed thereto in the
Merger Agreement), which provides, upon the terms and subject to the conditions
thereof, for the merger of the Company with and into a subsidiary of Parent (the
"MERGER"); and
 
    WHEREAS, as a condition to the willingness of Parent to enter into the
Merger Agreement, Parent has requested that each Stockholder agree, and, in
order to induce Parent to enter into the Merger Agreement, each Stockholder has
agreed, severally and not jointly, to grant Parent options to purchase such
Stockholder's Shares and proxies to vote such Stockholder's Shares;
 
    NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants set forth herein and in the Merger Agreement, the
parties hereto agree as follows:
 
                                   ARTICLE I
                                  THE OPTIONS
 
    SECTION 1.01.  GRANT OF OPTIONS.  Each Stockholder hereby grants to Parent
an irrevocable option (each, an "OPTION") to purchase such Stockholder's Shares
at (i) a price per share of Company Common Stock equal to $9.27 (the "COMMON
PURCHASE PRICE"), (ii) a price per share of AA Preferred equal to $10.00 (the
"AA PURCHASE PRICE"), and (iii) a price per share of F Preferred equal to $9.27
(the "F PURCHASE PRICE" and, together with the Common Purchase Price and the AA
Purchase Price, the "PURCHASE PRICE"). Each Option shall expire if (i) such
Option is not exercised prior to the close of business on the 120th day
following termination of the Merger Agreement, (ii) if the Merger Agreement is
terminated pursuant to Section 9.01(c) thereof, or (iii) if the Closing Date
Market Price is less than $12.07.
 
    SECTION 1.02.  EXERCISE OF OPTIONS.  (a) Provided that (i) to the extent
necessary, any applicable waiting periods (and any extension thereof) under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976 and the rules and
regulations promulgated thereunder (the "HSR ACT") with respect to the exercise
of an Option shall have expired or been terminated and (ii) no preliminary or
permanent injunction or other order, decree or ruling issued by any court or
governmental or regulatory authority, domestic or foreign, of competent
jurisdiction prohibiting the exercise of an Option or the delivery of Shares
shall be in effect, Parent may exercise any or all of the Options at any time
following the earlier of (i) the termination of the Merger Agreement (other than
a termination pursuant to Section 9.01(c) thereof) and (ii) the first occurrence
of a Competing Transaction until the expiration of such Options. In the event
that Parent wishes to exercise an Option, Parent shall give written notice (the
date of such notice being herein called the "NOTICE DATE"), to the Stockholder
who granted such Option specifying a place and date (not later than
 
                                       1
<PAGE>
ten Business Days (as defined below) and not earlier than three Business Days
following the Notice Date) for closing such purchase (the "CLOSING"). For the
purposes of this Agreement, the term "BUSINESS DAY" shall mean any day on which
banks are not required or authorized by law, regulation or executive order to
close in New York, New York.
 
    (b) If Parent shall exercise any Option in accordance with the terms of this
Agreement, and without additional consideration, the Stockholder who granted
such Option shall execute and deliver further transfers, assignments,
endorsements, consents and other instruments as Parent may reasonably request
for the purpose of effectively carrying out the transactions contemplated by
this Agreement and the Merger Agreement, including the transfer of any and all
of such Stockholder's Shares Parent and the release of any and all liens, claims
and encumbrances covering such Shares.
 
    SECTION 1.03.  PAYMENT FOR AND DELIVERY OF CERTIFICATES.  At the Closing,
(a) Parent shall pay the aggregate Purchase Price for the Shares being purchased
from each Stockholder by delivery of that number of shares of Parent Common
Stock (the "PARENT SHARES") equal to the quotient of the total amount of the
Purchase Price and the Closing Date Market Price (determined as if the Effective
Time had occurred on the Notice Date), (b) each Stockholder whose Shares are
being purchased shall deliver to Parent a certificate or certificates evidencing
such Stockholder's Shares, and such Stockholder agrees that such Shares shall be
transferred free and clear of all liens, and (c) Parent shall deliver to each
Stockholder a certificate or certificates evidencing the Parent Shares to be
received by each Stockholder at the Closing, and Parent agrees that such Parent
Shares shall be transferred free and clear of all liens. All such certificates
representing Shares shall be duly endorsed in blank, or with appropriate stock
powers, duly executed in blank, attached thereto, in proper form for transfer,
with the signature of such Stockholder thereon guaranteed, and with all
applicable taxes paid or provided for.
 
                                   ARTICLE II
                         TRANSFER AND VOTING OF SHARES
 
    SECTION 2.01.  TRANSFER OF SHARES.  During the term of the Options, and
except as otherwise provided herein, each Stockholder shall not (a) sell, pledge
or otherwise dispose of any of its Shares, (b) deposit its Shares into a voting
trust or enter into a voting agreement or arrangement with respect to such
Shares or grant any proxy with respect thereto or (c) enter into any contract,
option or other arrangement or undertaking with respect to the direct or
indirect acquisition or sale, assignment, transfer or other disposition of any
the Company Capital Stock.
 
    SECTION 2.02.  VOTING OF SHARES; FURTHER ASSURANCES.  (a) Each Stockholder,
by this Agreement, with respect to those Shares that it owns of record, does
hereby constitute and appoint Parent, or any nominee of Parent, with full power
of substitution, during and for the term of the Option granted by such
Stockholder hereunder (or, following termination of the Merger Agreement, during
such periods as the Options are exercisable), as its true and lawful attorney
and proxy, for and in its name, place and stead, to vote each of such Shares as
its proxy, at every annual, special or adjourned meeting of the stockholders of
the Company (including the right to sign its name (as stockholder) to any
consent, certificate or other document relating to the Company that the law of
the State of Colorado may permit or require) (i) in favor of the adoption of the
Merger Agreement and approval of the Merger and the other transactions
contemplated by the Merger Agreement, (ii) against any proposal for any
recapitalization, merger, sale of assets or other business combination between
the Company and any person or entity (other than the Merger) or any other action
or agreement that would result in a breach of any covenant, representation or
warranty or any other obligation or agreement of the Company under the Merger
Agreement or which could result in any of the conditions to the Company's
obligations under the Merger Agreement not being fulfilled, and (iii) in favor
of any other matter relating to consummation of the transactions contemplated by
the Merger Agreement. Each Stockholder further agrees to cause the Shares owned
by it beneficially to
 
                                       2
<PAGE>
be voted in accordance with the foregoing. Each Stockholder acknowledges receipt
and review of a copy of the Merger Agreement.
 
    (b) Each Stockholder shall perform such further acts and execute such
further documents and instruments as may reasonably be required to vest in
Parent the power to carry out the provisions of this Agreement.
 
                                  ARTICLE III
                       REPRESENTATIONS AND WARRANTIES OF
                                THE STOCKHOLDERS
 
    Each Stockholder, severally and not jointly, hereby represents and warrants
to Parent as follows:
 
    SECTION 3.01.  DUE ORGANIZATION, ETC.  Such Stockholder (if it is a
corporation, partnership or other legal entity) is duly organized and validly
existing under the laws of the jurisdiction of its incorporation or
organization. Such Stockholder has full power and authority (corporate or
otherwise) to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary action (corporate or otherwise) on the part of such
Stockholder. This Agreement has been duly executed and delivered by or on behalf
of such Stockholder and, assuming its due authorization, execution and delivery
by Parent, constitutes a legal, valid and binding obligation of such
Stockholder, enforceable against such Stockholder in accordance with its terms,
subject to the effect of any applicable bankruptcy, reorganization, insolvency,
moratorium or similar laws affecting creditors' rights generally and subject, as
to enforceability, to the effect of general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).
 
    SECTION 3.02.  NO CONFLICTS; REQUIRED FILINGS AND CONSENTS.  (a) The
execution and delivery of this Agreement by such Stockholder do not, and the
performance of this Agreement by such Stockholder will not, (i) conflict with or
violate the Certificate of Incorporation or By-Laws or similar organizational
document of such Stockholder (in the case of a Stockholder that is a
corporation, partnership or other legal entity), (ii) conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to such
Stockholder or by which it or any of its properties is bound or affected, or
(iii) result in any breach of or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, or result
in the creation of a lien or encumbrance on any of the property or assets of
such Stockholder or (if such Stockholder purports to be a corporation) any of
its subsidiaries pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which such Stockholder is a party or by which such Stockholder or any of its
properties is bound or affected, except for any such breaches, defaults or other
occurrences that would not cause or create a material risk of non-performance or
delayed performance by such Stockholder of its obligations under this Agreement.
 
    (b) The execution and delivery of this Agreement by such Stockholder do not,
and the performance of this Agreement by such Stockholder will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic or foreign, except (i)
for applicable requirements, if any, of the Securities Exchange Act of 1934, as
amended, and the rules and regulations thereunder (the "EXCHANGE ACT"), and the
HSR Act and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not
prevent or delay the performance by such Stockholder of its obligations under
this Agreement.
 
    SECTION 3.03.  TITLE TO SHARES.  Such Stockholder is the record or
beneficial owner of its Shares free and clear of any proxy or voting restriction
other than pursuant to this Agreement. At the Closing such Stockholder will
deliver good and valid title to its Shares free and clear of any pledge, lien,
security interest, charge, claim, equity, option, proxy, voting restriction,
right of first refusal or other limitation on
 
                                       3
<PAGE>
disposition or encumbrance of any kind, other than pursuant to this Agreement.
Such Stockholder has full right, power and authority to sell, transfer and
deliver its Shares pursuant to this Agreement. Upon delivery of such Shares and
payment of the Purchase Price therefor as contemplated herein, Parent will
receive good and valid title to such Shares, free and clear of any pledge, lien,
security interest, charge, claim, equity, option, proxy, voting restriction or
encumbrance of any kind.
 
                                   ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF PARENT
 
    Parent hereby represents and warrants to each Stockholder as follows:
 
    SECTION 4.01.  DUE ORGANIZATION, ETC.  Parent is a corporation duly
organized and validly existing under the laws of the State of Delaware. Parent

of Parent, enforceable against Parent in accordance with its terms.
 
    SECTION 4.02.  NO CONFLICT; REQUIRED FILINGS AND CONSENTS.  (a) The
execution and delivery of this Agreement by Parent do not, and the performance
of this Agreement by Parent will not, (i) conflict with or violate the
Certificate of Incorporation or By-laws of Parent, (ii) conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to Parent or by
which Parent or any of its properties is bound or affected, or (iii) result in
any breach of or constitute a default (or an event that with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance on any of the property or assets of Parent
pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease,
license, permit, franchise or other instrument or obligation to which Parent is
a party or by which it or any of its properties is bound or affected, except for
any such breaches, defaults or other occurrences that would not cause or create
a material risk of non-performance or delayed performance by Parent of its
obligations under this Agreement.
 
    (b) The execution and delivery of this Agreement by Parent do not, and the
performance of this Agreement by Parent will not, require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority, domestic or foreign, except (i) for applicable
requirements, if any, of the Exchange Act and the HSR Act and (ii) where the
failure to obtain such consents, approvals, authorizations or permits, or to
make such filings or notifications, would not prevent or delay the performance
by Parent of its obligations under this Agreement.
 
    SECTION 4.03.  INVESTMENT INTENT.  The purchase of Shares from any
Stockholder pursuant to this Agreement is for the account of Parent for the
purpose of investment and not with a view to or for sale in connection with any
distribution thereof within the meaning of the Securities Act of 1933, as
amended (the "SECURITIES ACT"), and the rules and regulations promulgated
thereunder.
 
                                   ARTICLE V
                              REGISTRATION RIGHTS
 
    SECTION 5.01.  SHELF REGISTRATION.  (a) Parent shall, within three months
following the Closing, file with the Securities and Exchange Commission (the
"COMMISSION") a shelf registration statement on an appropriate form under Rule
415 under the Securities Act, or any similar rule that may be adopted by the
Commission (a "SHELF REGISTRATION STATEMENT"), relating to the resale of the
Parent Shares by the Stockholders from time to time in accordance with the
methods of distribution set forth in such Shelf Registration
 
                                       4
<PAGE>
Statement and shall use its best efforts to cause such Shelf Registration
Statement to be declared effective under the Securities Act as soon as
practicable thereafter; PROVIDED, HOWEVER, that no Stockholder shall be entitled
to have the Parent Shares held by it covered by such Shelf Registration
Statement unless such Stockholder is in compliance with Section 5.02(f) hereof.
 
    (b) Parent shall use its best efforts to keep the Shelf Registration
Statement continuously effective in order to permit the prospectus forming part
thereof to be usable by the Stockholders until the earliest to occur of the
following: (A) two year anniversary of the Closing; (B) the earliest time at
which all the Parent Shares covered by the Shelf Registration Statement have
been sold pursuant to the Shelf Registration Statement; and (C) the earliest
time at which, in the written opinion of independent counsel to Parent, all
outstanding Parent Shares held by persons that are not affiliates of Parent may
be resold without registration under the Securities Act pursuant to Rule 144(k)
under the Securities Act or any successor provision thereto (in any such case,
such period being called the "EFFECTIVENESS PERIOD"). Parent shall be deemed not
to have used its best efforts to keep the Shelf Registration Statement effective
during the requisite period if Parent voluntarily takes any action that would
result in Stockholders of Parent Shares covered thereby not being able to offer
and sell any such Parent Shares during that period, unless (i) such action is
required by applicable law, (ii) the continued effectiveness of the Shelf
Registration Statement would require Parent to disclose a material financing,
acquisition or other corporate transaction, and the Board of Directors shall
have determined in good faith that such disclosure is not in the best interests
of Parent and its stockholders, or (iii) the Board of Directors shall have
determined in good faith that there is a valid business purpose for such
suspension.
 
    SECTION 5.02.  REGISTRATION PROCEDURES.  In connection with any Shelf
Registration Statement, the following provisions shall apply:
 
        (a) Parent shall take such action as may be necessary so that (i) any
    Shelf Registration Statement and any amendment thereto and any prospectus
    forming part thereof and any amendment or supplement thereto (and each
    report or other document incorporated therein by reference in each case)
    complies in all material respects with the Securities Act and the Exchange
    Act, and the respective rules and regulations thereunder, (ii) any Shelf
    Registration Statement and any amendment thereto does not, when it becomes
    effective, contain an untrue statement of a material fact or omit to state a
    material fact required to be stated therein or necessary to make the
    statements therein not misleading and (iii) any prospectus forming part of
    any Shelf Registration Statement, and any amendment or supplement to such
    prospectus, does not include an untrue statement of a material fact or omit
    to state a material fact necessary in order to make the statements, in the
    light of the circumstances under which they were made, not misleading.
 
        (b) Parent shall advise the Stockholders:
 
            (i) when a Shelf Registration Statement and any amendment thereto
       has been filed with the Commission and when the Shelf Registration
       Statement or any post-effective amendment thereto has become effective;
 
            (ii) upon the issuance by the Commission of any stop order
       suspending effectiveness of the Shelf Registration Statement or the
       initiation of any proceedings for that purpose;
 
           (iii) upon the receipt by Parent of any notification with respect to
       the suspension of the qualification of the securities included therein
       for sale in any jurisdiction or the initiation of any proceeding for such
       purpose; and
 
            (iv) upon the happening of any event that requires the making of any
       changes in the Shelf Registration Statement or the prospectus so that, as
       of such date, the Shelf Registration Statement and the prospectus do not
       contain an untrue statement of a material fact and do not omit to state a
       material fact required to be stated therein or necessary to make the
       statements therein (in the case of the prospectus, in light of the
       circumstances under which they were made)
 
                                       5
<PAGE>
       not misleading (which advice shall be accompanied by an instruction to
       suspend the use of the prospectus until the requisite changes have been
       made).
 
        (c) Parent shall, during the Effectiveness Period, deliver to each
    Stockholder with respect to a Shelf Registration Statement, without charge,
    as many copies of the prospectus (including each preliminary prospectus)
    included in such Shelf Registration Statement and any amendment or
    supplement thereto as such Stockholder may reasonably request; and Parent
    consents (except during the continuance of any event described in Section
    5.02(b)(iv)) to the use of the prospectus or any amendment or supplement
    thereto by each of the Stockholders in connection with the offering and sale
    of the Parent Shares covered by the prospectus or any amendment or
    supplement thereto during the Effectiveness Period.
 
        (d) Prior to any offering of Parent Shares pursuant to any Shelf
    Registration Statement, Parent shall register or qualify or cooperate with
    the Stockholders and their respective counsel in connection with the
    registration or qualification of such Parent Shares for offer and sale under
    the securities or blue sky laws of such jurisdictions as any such
    Stockholders reasonably request in writing and do any and all other acts or
    things necessary or advisable to enable the offer and sale in such
    jurisdictions of the Parent Shares covered by such Shelf Registration
    Statement; PROVIDED, HOWEVER, that in no event shall Parent be obligated to
    (i) qualify as a foreign corporation or as a dealer in securities in any
    jurisdiction where it would not otherwise be required to so qualify but for
    this Section 5.02(d), (ii) file any general consent to service of process in
    any jurisdiction where it is not as of the date hereof then so subject or
    (iii) subject itself to taxation in any jurisdiction if it is not so
    subject.
 
        (e) Upon the occurrence of any event contemplated by Section 5.02(b)(iv)
    above, Parent shall promptly prepare a post-effective amendment to any Shelf
    Registration Statement or an amendment or supplement to the related
    prospectus or file any other required document so that, as thereafter
    delivered to purchasers of the Parent Shares included therein, the
    prospectus will not include an untrue statement of a material fact or omit
    to state any material fact necessary to make the statements therein, in the
    light of the circumstances under which they were made, not misleading. If
    Parent notifies the Stockholders of the occurrence of any event contemplated
    by Section 5.02(b)(iv) above, the Stockholders shall suspend the use of the
    prospectus until the requisite changes to the prospectus have been made.
 
        (f) Parent may require each Stockholder with respect to a Shelf
    Registration Statement to furnish to Parent such information regarding the
    Stockholder and the distribution of Parent Shares held by such Stockholder
    as may be required by applicable law or regulation for inclusion in such
    Shelf Registration Statement and Parent may exclude from such registration
    the Parent Shares of any Stockholder that fails to furnish such information
    within a reasonable time after receiving such request.
 
        (g) Parent will use its best efforts to cause the Parent Shares to be
    listed on the New York Stock Exchange or other stock exchange or trading
    system on which the Parent Common Stock primarily trades on or prior to the
    effective date of any Shelf Registration Statement hereunder.

    SECTION 6.01.  REPURCHASE OPTION.  For a period of 30 days after the
consummation of a Competing Transaction involving the Company (a "REPURCHASE
EVENT"), Parent shall have the right, upon five business days' prior written
notice to the Company (or any successor in interest to the Company by merger,
sale of all or substantially all of the assets, or otherwise) (the "REPURCHASE
NOTICE"), to cause the Company (or any successor in interest to the Company by
merger, sale of all or substantially all of the assets, or otherwise) to have a
closing and to pay at such closing (and the Company and such successor, jointly
and
 
                                       6
<PAGE>
severally, shall be obligated to pay) to Parent in consideration for the
cancellation of all or any portion of the Options, and/or the repurchase from
Parent of all or any portion of the Shares acquired by Parent pursuant to
exercise of Options, as the case may be, an aggregate price (the "REPURCHASE
PRICE") equal to the sum of the following amounts for each class of Company
Capital Stock: (A) the product of (x) the number of Shares of such class as to
which the Option remains exercisable multiplied by (y) the amount by which (i)
the value of the per share consideration paid for such class in the Competing
Transaction exceeds (ii) the Purchase Price for such class and (B) the product
of (x) the number of Shares of such class that Parent owns as a result of
exercise of an Option and (y) the per share consideration paid for such class in
the Competing Transaction. At any closing contemplated by the Repurchase Notice,
the Company (or any successor in interest to the Company by merger, sale of all
or substantially all of the assets, or otherwise) shall pay to Parent the
Repurchase Price by delivering to Parent a certified or bank check payable to or
on the order of Parent in an amount equal to the Repurchase Price.

otherwise defined herein are used herein as therein defined), among SUN

                                  WITNESSETH:
 
    WHEREAS, Parent, Merger Sub, and the Company desire to amend the Merger
Agreement as provided in Amendment No. 3 thereto dated of even date herewith;
and
 
    WHEREAS, in connection therewith Parent and each Stockholder desire to amend

    NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties, covenants and agreements set forth herein, and other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, and intending to be legally bound hereby, the parties hereto
hereby agree as follows:
 
    SECTION 1:  AMENDMENT TO AGREEMENT.  The Agreement is hereby amended as
follows:
 
        (a) Section 1.01 of the Agreement is hereby amended and restated in its
    entirety as follows:
 
           "Section 1.01.  GRANT OF OPTIONS.  Each Stockholder hereby grants to
       Parent an irrevocable option (each, an "OPTION") to purchase such

       equal to $10.00 (the "COMMON PURCHASE PRICE"), (ii) a price per share of
       AA Preferred equal to $10.00 ( the "AA PURCHASE PRICE"), and (iii) a
       price per share of F Preferred equal to $9.00 (the "F PURCHASE PRICE"

       termination of the Merger Agreement, or (ii) if the Merger Agreement is
       terminated pursuant to Section 9.01(c) thereof or terminated or
       terminable pursuant to Section 9.01(h)."
 
    SECTION 2.  REPRESENTATIONS AND WARRANTIES.
 
        (a)  REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS.  Each

    its obligations under the Agreement as amended hereby and to consummate the
    transactions contemplated hereby. The execution and delivery of this
    Amendment by such Stockholder and the consummation by such Stockholder of
    the transactions contemplated by the Agreement as amended hereby have been
    duly and validly authorized by all necessary action (corporate or otherwise)
    on the part of such Stockholder. This Amendment has been duly executed and
    delivered by such Stockholder and, assuming the due authorization, execution
    and delivery by Parent, constitutes the legal, valid and binding obligation
    of such Stockholder, enforceable against such Stockholder in accordance with
    its terms.
 
        (b)  REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB.  Parent
    and Merger Sub hereby jointly and severally represent and warrant to each
    Stockholder that: Parent and Merger Sub have all necessary corporate power
    and authority to execute and deliver this Amendment, to perform their
    respective obligations under the Agreement as amended hereby and to
    consummate the transactions contemplated hereby. The execution and delivery
    of this Amendment by Parent and Merger Sub and the consummation by Parent
    and Merger Sub of the transactions contemplated by the Merger Agreement as
    amended hereby have been duly and validly authorized by all necessary
    corporate
 
                                       1

    action (other than stockholder approval as described in the Merger
    Agreement). This Amendment has been duly executed and delivered by Parent
    and Merger Sub and, assuming the due authorization, execution and delivery
    by the Company, constitutes the legal, valid and binding obligation of
    Parent and Merger Sub, enforceable against Parent and Merger Sub in
    accordance with its terms.
 
    SECTION 3.  EFFECT ON AGREEMENT.  Except as otherwise specifically provided
herein, the Agreement shall not be amended but shall remain in full force and
effect.
 
    SECTION 4.  COUNTERPARTS.  This Amendment may be signed in one or more
counterparts, each of which shall be an original but all of which, taken
together, shall constitute one and the same instrument.
 
    IN WITNESS WHEREOF, the parties hereto have executed this Amendment as of
the date first written above.

    included in the form of amended Forms 10-Q that will be filed with the SEC
    pertaining to the matters described in Section 4.07(a) of Schedule I to
    Amendment No. 2 to this Agreement shall not differ in any respect from the
    information included in Section 4.07(a) of Schedule I to Amendment No. 2 to
    this Agreement without the prior written consent of Parent. The Company
    shall not file with the SEC any amendment to any Company Report without the

    Section 6.13.
 
        SECTION 6.14.  CONSENT OF ACCOUNTANTS; WORK PAPERS.  (a) The Company

that will preclude "pooling of interests" accounting treatment for the Merger
under applicable United States accounting rules, including all computer files
and other material prepared by Coopers & Lybrand L.L.P. in connection with such
analysis; PROVIDED, HOWEVER, that the Company shall not be required under this
Section 6.14(b) to pay any amounts claimed by Coopers & Lybrand L.L.P. which, in
the Company's good faith exercise of its reasonable judgment, are subject to
valid claims of set-off or other defenses or counterclaims."
 
    (j) Section 7.04 of the Merger Agreement is hereby amended and restated in
its entirety to read as follows:
 
        "SECTION 7.04.  DIRECTORS' AND OFFICERS' INDEMNIFICATION.  (a) The
    articles of incorporation and bylaws of the Surviving Corporation shall
    contain the provisions with respect to indemnification that are set forth,
    as of the date of this Agreement, in the articles of incorporation and
    bylaws of the Company, which provisions shall not be amended, repealed or
    otherwise modified for a period of six years from the Effective Time in any
    manner that would affect adversely the rights thereunder of individuals who
    at or at any time prior to the Effective Time were directors or officers of
    the Company; PROVIDED, HOWEVER, that the Surviving Corporation may amend or
    otherwise modify the provisions with respect to indemnification that are set
    forth in its articles of incorporation and bylaws to exclude any right to
    indemnification thereunder with respect to any civil or criminal penalties,
    damages, fines, disgorgement or other similar personal liabilities, or any
    injunctions or consent decrees, incurred, imposed or entered into in
    connection with any claim, action, suit, proceeding or investigation,
    whether civil, criminal, administrative or investigative, brought or
    assessed by any Governmental Entity or any settlement thereof ("EXCLUDED
    ITEMS").
 
                                       3
<PAGE>
        (b) From and after the Effective Time, Parent and the Surviving
    Corporation shall indemnify and hold harmless each present and former
    director and officer of the Company (the "INDEMNIFIED PARTIES"), against (i)
    any costs or expenses (including reasonable attorneys' fees) and (ii)
    judgments, fines, losses, claims, damages or liabilities, but excluding from
    this clause (ii) Excluded Items (collectively, "COSTS"), incurred in
    connection with any claim, action, suit, proceeding or investigation,
    whether civil, criminal, administrative or investigative, arising out of or
    pertaining to matters existing or occurring at or prior to the Effective
    Time, whether asserted or claimed prior to, at or after the Effective Time,
    to the extent permitted under the articles of incorporation and bylaws of
    the Company or Parent (each as in effect on the Effective Date).
 
        (c) If any Indemnified Party shall seek indemnification pursuant to this
    Section 7.04, such Indemnified Party shall give prompt notice to Parent and
    the Surviving Corporation, stating the amount of the Costs, if known, and
    method of computation thereof. The obligations and liabilities of Parent and
    the Surviving Corporation under this Section 7.04 with respect to Costs
    arising from any claims, actions, suits, proceedings or investigations of
    any third party, including any Governmental Entity, which are subject to the
    indemnification provided for in this Section 7.04 ("THIRD PARTY CLAIMS")
    shall be governed by and contingent upon the following additional terms and
    conditions: if an Indemnified Party shall receive notice of any Third Party
    Claim, the Indemnified Party shall give Parent and the Surviving Corporation
    notice of such Third Party Claim within 10 days of the receipt by the
    Indemnified Party of such notice; PROVIDED, HOWEVER, that the failure to
    provide such notice shall not release Parent and the Surviving Corporation
    from any of its obligations under this Section 7.04 except to the extent
    Parent and the Surviving Corporation are materially prejudiced by such
    failure. Upon receipt of notice from an Indemnified Party as provided in
    this Section 7.04(c), Parent and the Surviving Corporation shall be entitled
    to assume and control the defense of such Third Party Claim at their expense
    and through counsel of their choice if they give notice of their intention
    to do so to the Indemnified Party within 30 days of the receipt of such
    notice from the Indemnified Party. In the event that any Indemnified Party
    shall seek indemnification as provided herein, the Indemnified Party shall
    make available to Parent and the Surviving Corporation, at Parent's and the
    Surviving Corporation's expense, all witnesses, pertinent records, materials
    and information in the Indemnified Party's possession or under the
    Indemnified Party's control relating thereto as is reasonably required by
    Parent and the Surviving Corporation;
 
        (d) Notwithstanding anything set forth in this Section 7.04 to the
    contrary, (i) if there exists a conflict of interest that would make it
    inappropriate for the same counsel to represent both the Indemnified Party
    and Parent and the Surviving Corporation in connection with any Third Party
    Claim (other than an Excluded Item), then the Indemnified Party shall be
    entitled to retain its own counsel that is reasonably satisfactory to Parent
    and the Surviving Corporation at the expense of Parent and the Surviving
    Corporation, (ii) if there exists or is reasonably likely to exist a
    conflict of interest that would make it inappropriate in the judgment of the
    Indemnified Party for the same counsel to represent both the Indemnified
    Party and Parent and the Surviving Corporation in connection with any
    Excluded Item, then the Indemnified Party shall be entitled to retain its
    own counsel at its own expense, and (iii) if there exists or is reasonably
    likely to exist a conflict of interest that would make it inappropriate in
    the judgment of the counsel selected by Parent to defend an Excluded Item
    for the same counsel to represent both the Indemnified Party and Parent and
    the Surviving Corporation in connection with such Excluded Item, then the
    Indemnified Party shall retain its own counsel at its own expense."
 
    (k) Section 9.01(b) of the Merger Agreement is hereby amended and restated
in its entirety to read as follows:
 
        "(b) by either Parent or the Company, if the Effective Time shall not
    have occurred on or before November 30, 1997; PROVIDED, HOWEVER, that in the
    event that the Effective Time has not occurred by such time (i) due to the
    failure to satisfy the condition specified in Section 8.01(b), and as of
    such time
 
                                       4
<PAGE>
    (A) the condition specified in Section 8.01(a) shall have been satisfied,

    Stockholders' Meeting, shall have been held, and (C) neither Parent nor the
    Company shall be entitled to terminate this Agreement under any other
    paragraph of this Section 9.01, then such date shall be extended, without
    any action on the part of any party hereto, until December 31, 1997; or (ii)
    solely due to the failure to satisfy the condition specified in Section
    8.01(d) or 8.01(e), then such date may be extended, at the option of Parent,
    until December 31, 1997; and PROVIDED, FURTHER, that the right to terminate
    this Agreement under this Section 9.01(b) shall not be available to any
    party whose failure to fulfill any obligation under this Agreement shall
    have caused, or resulted in, the failure of the Effective Time to occur on
    or before such date."
 
    (l) Section 9.01(g) of the Merger Agreement is hereby amended and restated
in its entirety to read as follows:
 
        "(g) by Parent, upon a breach of any representation, warranty, covenant
    or agreement on the part of the Company set forth in this Agreement, or if
    any representation or warranty of the Company shall have become untrue,
    incomplete or incorrect, in either case such that the conditions set forth
    in Section 8.03 would not be satisfied (a "TERMINATING COMPANY BREACH");
    PROVIDED, HOWEVER, that if such Terminating Company Breach (i) is curable by
    the Company through the exercise of its reasonable efforts within 30 days
    and for so long as the Company continues to exercise such reasonable
    efforts, or (ii) has been disclosed on Schedule I, II or III to Amendment
    No. 1 to this Agreement or on Schedule I to Amendment No. 2 to this
    Agreement, Parent may not terminate this Agreement under this Section
    9.01(g); and PROVIDED FURTHER that the preceding proviso shall not in any
    event be deemed to extend any date set forth in paragraph (b) of this
    Section 9.01;"
 
    (m) Section 9.01(k) of the Merger Agreement is hereby amended and restated
in its entirety to read as follows:
 
        "(k) by the Company, if the Company shall have failed to obtain the
    Company Fairness Opinion by the close of business (New York City time) on
    August 27, 1997; PROVIDED, HOWEVER, that Parent may extend such date by up
    to ten business days by delivering written notice thereof to the Company;
    and PROVIDED, FURTHER that such termination shall not be effective unless
    and until the Company shall have paid to Parent an amount equal to all of
    Parent's Expenses, as evidenced by reasonable documentation, in an amount no
    greater than $750,000, by wire transfer of immediately available funds to an
    account designated by Parent; or".
 
    (n) Section 9.01 of the Merger Agreement is hereby amended by deleting the
word "or" immediately preceding clause (k) thereof and adding the following
clause (l) immediately following clause (k) thereof:
 
        "(l) by Parent, if the letter of Coopers & Lybrand L.L.P. required by
    Item 304(a)(3) of Regulation S-K expresses any material disagreement with
    the contents of the Current Report on Form 8-K filed by the Company with the
    SEC on August 21, 1997."

The Board of Directors
 
Sun Healthcare Group
 
Attention:  Andy Turner
        President and CEO
 
Ladies and Gentlemen:
 
    You have requested our opinion as to the fairness, from a financial point of
view, to Sun Healthcare Group Inc. (the "Company" or "Sun") of the consideration
proposed to be paid by the Company in connection with the proposed merger ("the
Merger") of a wholly-owned subsidiary of the Company ("the Merger Subsidiary")
with Retirement Care Associates (the "Seller" or "RCA"). Pursuant to the
Agreement and Plan of Merger and Reorganization, dated as of February 17, 1997
as amended by Amendment No. 1 thereto dated May 27, 1997, Amendment No. 2
thereto dated as of August 21, 1997 and Amendment No. 3 thereto dated as of
November 25, 1997 (as amended, the "Agreement"), among the Merger Subsidiary,
the RCA, and Sun, RCA will become a wholly-owned subsidiary of Sun, and Sun will
pay (i) for each share of Common Stock, par value $0.0001 per share, of RCA
("RCA Common Stock") consideration equal to Common Stock of Sun ("Sun Common
Stock") having a market value, based on an average closing price for Sun Common
Stock, equal to $10.00 per share (unless the average closing price exceeds
$24.20 per share, in which case each outstanding share of RCA Common Stock will
be converted into a right to receive 0.413 shares of Sun Common Stock, or unless
such an average closing price is less than $19.80 per share, in which case each
outstanding share of RCA Common Stock will be converted into the right to
receive 0.505 shares of Sun Common Stock), (ii) for each share of Series AA
Preferred Stock of RCA the right to receive shares of Sun Common Stock having a
market value, based on an average closing price for Sun Common Stock, equal to
$10.00 per share, and (iii) for each share of Series F Preferred Stock of RCA
one share of Sun Preferred Stock, which shares of Sun Preferred Stock shall
thereafter be convertible into the number of shares of Sun Common Stock that
such shares of RCA Series FF Preferred Stock would have been converted into if
converted immediately prior to the effective time of the RCA merger.
 
    In arriving at our opinion, we have reviewed (i) the Agreement; (ii) certain
publicly available information concerning the business of the Seller and of
certain other companies engaged in businesses comparable to those of the Seller,
and the reported market prices for certain other companies' securities deemed
comparable; (iii) publicly available terms of certain transactions involving
companies comparable to the Seller and the consideration received for such
companies; (iv) current and historical market prices of the Common Stock of the
Seller; (v) the audited financial statements of the Company for the fiscal year
ended December 31, 1994, December 31, 1995, and December 31, 1996 and the Seller
for the fiscal year ended June 30, 1995, June 30, 1996 and June 30, 1997 and the
audited financial statements of the Seller and the Company for the period ended
September 30, 1997; (vi) certain agreements with respect to outstanding
indebtedness or obligations of the Company and the Seller; (vii) certain
internal financial analyses and forecasts prepared by the Seller, the Company,
and their respective managements; and (viii) the terms of other business
combinations that we deemed relevant.
 
    In addition, we have held discussions with certain members of the management
of the Company and the Seller with respect to certain aspects of the Merger, and
the past and current business operations of the Company and the Seller, the
financial condition and future prospects and operations of the Company and the
Seller, the effects of the Merger on the financial condition and future
prospects of the Company and the Seller, and certain other matters we believed
necessary or appropriate to our inquiry. We have visited
<PAGE>
certain representative facilities of the Seller, and reviewed such other
financial studies and analyses and considered such other information as we
deemed appropriate for the purposes of this opinion.
 
    In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was publicly
available or was furnished to us by the Company and the Seller or otherwise
reviewed by us, and we have not assumed any responsibility or liability
therefor. We have not conducted any valuation or appraisal of any assets or
liabilities, nor have any such valuations or appraisals been provided to us. In
relying on financial analyses and forecasts provided to us, we have assumed that
they have been reasonably prepared based on assumptions reflecting the best
currently available estimates and judgments by management as to the expected
future results of operations and financial condition of the Company and the
Seller. We have also assumed that the Merger will be a tax free reorganization.
We have relied as to all legal matters relevant to rendering our opinion upon
the advice of counsel to the Company. We have also considered the material
synergies that the management of the Company believes can be attained as a
result of the Merger. We have assumed that these synergies reflect the best
currently available estimates of management of the Company and will be readily
achieved.
 
    Our opinion is necessarily based on economic, market and other conditions as
in effect on, and the information made available to us as of, the date hereof.
It should be understood that subsequent developments may affect this opinion and
that we do not have any obligation to update, revise, or reaffirm this opinion.
We are expressing no opinion herein as to the price at which the Company's
Common Stock will trade at any future time.
 
    We have acted as financial advisor to the Company with respect to the
proposed Merger and will receive a fee from the Company for our services. We
will also receive an additional fee if the proposed Merger is consummated. J.P.
Morgan Securities Inc continues to advise the Company on financial and strategic
matters. In the ordinary course of their businesses, our affiliates may actively
trade the debt and equity securities of the Company or the Seller for their own
account or for the accounts of customers and, accordingly, they may at any time
hold long or short positions in such securities.
 
    On the basis of and subject to the foregoing, it is our opinion as of the
date hereof that the consideration to be paid by the Company in the proposed
Merger is fair, from a financial point of view, to the Company.
 
    This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Merger. This
opinion does not constitute a recommendation to any stockholder of the Company
as to how such stockholder should vote with respect to the Merger. This opinion
may not be disclosed, referred to, or communicated (in whole or in part) to any
third party for any purpose whatsoever except with our prior written consent in
each instance. This opinion may be reproduced in full in any proxy or
information statement mailed to stockholders of the Company but may not
otherwise be disclosed publicly in any manner without our prior written approval
and must be treated as confidential.
 
                                          Very truly yours,
                                          J.P. MORGAN SECURITIES INC.

before such date, the corporation may, in lieu of making the payment provided in
section 7-113-206, offer to make such payment if the dissenter agrees to accept
it in full satisfaction of the demand.
 
    (2) An offer to make payment under subsection (1) of this section shall
include or be accompanied by the information required by section 7-113-206 (2).
 
    7-113-209 PROCEDURE IF DISSENTER IS DISSATISFIED WITH PAYMENT OR OFFER.--(1)
A dissenter may give notice to the corporation in writing of the dissenter's
estimate of the fair value of the dissenter's shares and of the amount of
interest due and may demand payment of such estimate, less any payment made
under section 7-113-206, or reject the corporation's offer under section
7-113-208 and demand payment of the fair value of the shares and interest due,
if:
 
        (a) The dissenter believes that the amount paid under section 7-113-206
    or offered under section 7-113-208 is less that the fair value of the shares
    or that the interest due was incorrectly calculated;
 
        (b) The corporation fails to make payment under section 7-113-206 within
    sixty days after the date set by the corporation by which the corporation
    must receive the payment demand; or
 
        (c) The corporation does not return the deposited certificates or
    release the transfer restrictions imposed on uncertificated shares as
    required by section 7-113-207 (1).
 
    (2) A dissenter waives the right to demand payment under this section unless
the dissenter causes the corporation to receive the notice required by
subsection (1) of this section within thirty days after the corporation made or
offered payment for the dissenter's shares.
 
                                     PART 3
                          JUDICIAL APPRAISAL OF SHARES
 
    7-113-301  COURT ACTION.--(1)  If a demand for payment under section
7-113-209 remains unresolved, the corporation may, within sixty days after
receiving the payment demand, commence a proceeding and petition the court to
determine the fair value of the shares and accrued interest. If the corporation
does not commence the proceeding within the sixty-day period, it shall pay to
each dissenter whose demand remains unresolved the amount demanded.
 
    (2) The corporation shall commence the proceeding described in subsection
(1) of this section in the district court of the county in this state where the
corporation's principal office is located or, if (1)the corporation has no
principal office in this state, in the district court of the county in which its
registered office is located. If the corporation is a foreign corporation
without a registered office(2), it shall commence the proceeding in the country
where the registered office of the domestic corporation merged into, or whose
shares were acquired by, the foreign corporation was located.
 
    (3) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unresolved parties to the proceeding commenced
under subsection (2) of this section as in an action against their shares, and
all parties shall be served with a copy of the petition. Service on each
dissenter shall be by registered or certified mail, to the address stated in
such dissenter's payment demand, or if no such address is stated in the payment
demand, at the address shown on the corporation's current record of shareholders
for the record shareholder holding the dissenter's shares, or as provided by
law.
 
    (4) The jurisdiction of the court in which the proceeding is commenced under
subsection (2) of this section is plenary and exclusive. The court may appoint
one or more persons as appraisers to receive evidence and recommend a decision
on the question of fair value. The appraisers have the powers described in the
order appointing them, or in any amendment to such order. The parties to the
proceeding are entitled to the same discovery rights as parties in other civil
proceedings.
 
                                       6
<PAGE>
    (5) Each dissenter made a party to the proceeding commenced under subsection
(2) of this section is entitled to judgment for the amount, if any, by which the
court finds the fair value of the dissenter's shares, plus interest, exceeds the
amount paid by the corporation, or for the fair value, plus interest, of the
dissenter's shares for which the corporation elected to withhold payment under
section 7-113-208.
 
    7-113-302  COURT COSTS AND COUNSEL FEES.--(1)  The court in an appraisal
proceeding commenced under section 7-113-301 shall determine all costs of the
proceeding, including the reasonable compensation and expenses of appraisers
appointed by the court. The court shall assess the costs against the
corporation: except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding
payment under section 7-113-209.
 
    (2) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:
 
        (a) Against the corporation and in favor of any dissenters if the court
    finds the corporation did not substantially comply with the requirements of
    part 2 of this article; or
 
        (b) Against either the corporation or one or more dissenters, in favor
    of any other party, if the court finds that the party against whom the fees
    and expenses are assessed acted arbitrarily, vexatiously, or not in good
    faith with respect to the rights provided by this article.
 
    (3) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to said counsel reasonable fees to be paid out of the amounts awarded to
the dissenters who were benefitted.

    SECTION 3.02.  EXCHANGE OF SHARES OTHER THAN TREASURY SHARES AND DISSENTING
SHARES.  Subject to the terms and conditions hereof, at or prior to the
Effective Time, Parent shall appoint an exchange agent to effect the exchange of
shares of Company Capital Stock (other than Dissenting Shares) for Parent Common
Stock or cash, as the case may be, in accordance with the provisions of this
Article III (the "EXCHANGE AGENT"). From time to time after the Effective Time,
Parent shall deposit, or cause to be deposited, certificates representing Parent
Common Stock for conversion of shares of Company Capital Stock (other than
Dissenting Shares) or cash, as the case may be, in accordance with the
provisions of Section 3.01 (such certificates or cash, together with any
dividends or distributions with respect thereto, being herein referred to as the
"EXCHANGE FUND"). Commencing immediately after the Effective Time and until the
appointment of the Exchange Agent shall be terminated, each holder of a
certificate or certificates theretofore representing shares of Company Capital
Stock (other than Dissenting Shares) may surrender the same to the Exchange
Agent and, after the appointment of the Exchange Agent shall be terminated, any
such holder may surrender any such certificate to Parent. Such holder shall be
entitled upon such surrender to receive in exchange therefor a certificate or
certificates representing the number of full shares of Parent Common Stock or
cash into which the shares of Company Capital Stock theretofore represented by
the certificate or certificates so surrendered shall have been converted in
accordance with the provisions of Section 3.01, together with a cash payment in
lieu of fractional shares, if any, in accordance with Section 3.04, and any such
shares of Parent Common Stock shall be deemed to have been issued at the
Effective Time. Until so surrendered and exchanged, each outstanding certificate
which, prior to the Effective Time, represented issued and outstanding shares of
Company Capital Stock shall be deemed for all corporate purposes of Parent,
other than the payment of dividends and other distributions, if any, to evidence
ownership of the number of full shares of Parent Common Stock or cash into which
the shares of Company Capital Stock theretofore represented thereby shall have
been converted at the Effective Time. Unless and until any such certificate
theretofore representing shares of Company Capital Stock is so surrendered, no
dividend or other distribution, if any, payable to the holders of record of
Parent Common Stock as of any date subsequent to the Effective Time shall be
paid to the holder of such certificate in respect thereof. Upon the surrender of
any such certificate theretofore representing shares of Company Capital Stock,
however, the record holder of the certificate or certificates representing
shares of Parent Common Stock issued in exchange therefor shall receive from the
Exchange Agent or from Parent, as the case may be, payment of the amount of
dividends and other distributions, if any, which as of any date subsequent to
the Effective Time and until such surrender shall have become payable with
respect to such number of shares of Parent Common Stock ("PRESURRENDER
DIVIDENDS"). No interest shall be payable with respect to the payment of
Presurrender Dividends upon the surrender of certificates theretofore
representing shares of Company Capital Stock. After the appointment of the
Exchange Agent shall have been terminated, such holders of Parent Common Stock
which have not received payment of Presurrender Dividends shall look only to
Parent for payment thereof. Notwithstanding the foregoing provisions of this
Section 3.02, risk of loss and title to such certificates representing shares of
Company Capital Stock shall pass only upon proper delivery of such certificates
to the Exchange Agent, and neither the Exchange Agent nor any party hereto shall
be liable to a holder of shares of Company Capital Stock for any Parent Common
Stock or dividends or distributions thereon delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law or to a
transferee pursuant to Section 3.03. In the
 
                                       8
<PAGE>
event that this Agreement shall have been terminated pursuant to Section 9.01
hereof, the Company and Parent shall cause the Exchange Agent to use its
commercially reasonable efforts to effect the prompt return of stock
certificates representing shares of Company Capital Stock to the holders
thereof.
 
    SECTION 3.03.  STOCK TRANSFER BOOKS.  (a) At the Effective Time, each of the
stock transfer books of the Company with respect to shares of Company Capital
Stock shall be closed, and there shall be no further registration of transfers
of shares of Company Capital Stock thereafter on the records of any such stock
transfer books. In the event of a transfer of ownership of shares of Company
Capital Stock that is not registered in the stock transfer records of the
Company, at the Effective Time, a certificate or certificates representing the
number of full shares of Parent Common Stock into which such shares of Company
Capital Stock shall have been converted shall be issued to the transferee
together with a cash payment in lieu of fractional shares, if any, in accordance
with Section 3.04, and a cash payment in the amount of Presurrender Dividends,
if any, in accordance with Section 3.02, if the certificate or certificates
representing such shares of Company Capital Stock is or are surrendered as
provided in Section 3.02, accompanied by all documents required to evidence and
effect such transfer and by evidence of payment of any applicable stock transfer
tax.
 
    (b) Notwithstanding anything to the contrary herein, certificates
surrendered for exchange by any person constituting a Rule 145 Affiliate of the
Company shall not be exchanged until Parent shall have received from such person
an executed Company Affiliate Agreement, as provided in Section 7.03.
 
    SECTION 3.04  NO FRACTIONAL SHARE CERTIFICATES.  Unless Parent otherwise
determines, no scrip or fractional share certificates for Parent Common Stock
shall be issued upon the surrender for exchange of certificates evidencing
shares of Company Capital Stock, and an outstanding fractional share interest
shall not entitle the owner thereof to vote, to receive dividends or to any
rights of a stockholder of Parent or of the Surviving Corporation with respect
to such fractional share interest. In lieu of fractional shares, each holder of
shares of Company Capital Stock who, except for the provisions of this Section
3.04, would be entitled to receive a fractional share of Parent Common Stock
shall, upon surrender of the certificate or certificates representing shares of
Company Capital Stock, be entitled to receive an amount in cash (rounded to the
nearest whole cent), without interest, equal to the product obtained by
multiplying (a) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Company Capital
Stock held at the Effective Time by such holder) by (b) the closing price for a
share of Parent Common Stock on the NYSE on the first business day immediately
prior to the Effective Time. At or prior to the Effective Time, Parent shall pay
to the Exchange Agent an amount in cash (the "CASH DEPOSIT") sufficient for the
Exchange Agent to pay each holder of Company Capital Stock the amount of cash in
lieu of fractional shares to which such holder is entitled pursuant to this
Section 3.04. As soon as practicable after the determination of the amount of
cash, if any, to be paid to holders of Company Capital Stock with respect to any
fractional share interests, the Exchange Agent shall make available such
amounts, net of any required withholding, to such holders of Company Capital
Stock, subject to and in accordance with the terms of Section 3.02. In no event
shall either (i) the total cash consideration paid to holders of Company Capital
Stock in lieu of fractional shares exceed one percent (1%) of the value of the
total consideration issued to holders of Company Capital Stock in exchange for
their Company Capital Stock or (ii) any holder of Company Capital Stock,
directly or indirectly, receive cash in an amount equal to or greater than the
value of one full share of Parent Company Stock.
 
    SECTION 3.05  OPTIONS AND WARRANTS TO PURCHASE COMPANY COMMON STOCK.  At the
Effective Time, each option or warrant granted by the Company to purchase shares
of Company Common Stock (each, a "COMPANY STOCK OPTION") which is outstanding
and unexercised immediately prior to the Effective Time shall be assumed by
Parent and converted into an option or warrant to purchase shares of Parent
Common Stock in such number and at such exercise price as provided below and
otherwise having the same terms
 
                                       9
<PAGE>
and conditions as in effect immediately prior to the Effective Time (except to
the extent that such terms, conditions and restrictions may be altered in
accordance with their terms as a result of the Merger):
 
        (a) the number of shares of Parent Common Stock to be subject to the new
    option or warrant shall be equal to the product of (i) the number of shares
    of Company Common Stock subject to the original option or warrant and (ii)
    the Common Exchange Ratio;
 
        (b) the exercise price per share of Parent Common Stock under the new
    option or warrant shall be equal to the quotient of (i) the exercise price
    per share of Company Common Stock under the original option or warrant
    divided by (ii) the Common Exchange Ratio; and
 
        (c) upon each exercise of options or warrants by a holder thereof, the
    aggregate number of shares of Parent Common Stock deliverable upon such
    exercise shall be rounded down, if necessary, to the nearest whole share and
    the aggregate exercise price shall be rounded up, if necessary, to the
    nearest cent.
 
    The adjustments provided herein with respect to any options which are
"incentive stock options" (as defined in Section 422 of the Code) shall be
effected in a manner consistent with the requirements of Section 424(a) of the
Code.
 
    SECTION 3.06  CERTAIN ADJUSTMENTS.  If between the date of this Agreement
and the Effective Time, the outstanding shares of Company Capital Stock or
Parent Common Stock shall be changed into a different number of shares by reason
of any reclassification, recapitalization, split-up, combination or exchange of
shares, or any dividend payable in stock or other securities shall be declared
thereon with a record date within such period or the number of shares of Company
Capital Stock on a fully diluted basis is in excess of that specified in Section
4.03 and disclosed in 4.03 of the Company Disclosure Schedule (regardless of
whether such excess is a result of an additional issuance of capital stock or a
correction to such Sections), but excluding options permitted to be issued
pursuant to Section 6.01(b) hereof, then, the exchange ratios established
pursuant to the provisions of Section 3.01 shall be adjusted accordingly to
provide to the holders of Company Capital Stock the same economic effect as
contemplated by this Agreement prior to such reclassification, recapitalization,
split-up, combination, exchange, dividend or increase.
 
    SECTION 3.07  UNDISTRIBUTED AMOUNTS.  Any portion of the Exchange Fund or
the Cash Deposit which remains undistributed for six months after the Effective
Time shall be delivered to Parent, and any holder of Company Capital Stock who
has not theretofore complied with the provisions of this Article III shall
thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock or any cash in lieu of fractional shares of Parent Common Stock and
any Presurrender Dividends.
 
    SECTION 3.08  DISSENTING SHARES.  Notwithstanding any provision of Section
3.01 hereof to the contrary, shares of Company Capital Stock which are held by
holders of such shares who have not voted in favor of the Merger, who are
entitled to dissent and who have delivered a written notice of intent to demand
payment for such shares in the manner provided in Section 481 et seq. of the
General Corporation Law ("DISSENTING SHARES"), shall not be converted into or
exchanged for or represent the right to receive any shares of Parent Common
Stock, unless such holder fails to perfect or effectively withdraws or loses
such rights to payment. If, after the Effective Time, such holder fails to
perfect or effectively withdraws or loses such right to payment, then such
Dissenting Shares shall thereupon be deemed to have been converted into and
exchanged pursuant to Section 3.01 hereof, as of the Effective Time, for the
right to receive shares of Parent Common Stock issued in the Merger to which the
holder of such shares of Company Capital Stock is entitled, without any interest
thereon. The Company shall give Parent prompt notice of any notices and demands
received by the Company for payment for shares of Company Capital Stock, and
Parent shall have the right to participate in all negotiations and proceedings
with respect to such notices and demands. The Company shall not, except with the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands. Prior to the Effective Time, the
 
                                       10
<PAGE>
Company shall establish an escrow account with a financial institution and the
Company shall fund such escrow account with cash or cash equivalents in an
amount sufficient to make all payments to holders of Dissenting Shares. Such
escrow account shall survive the Merger. All payments to holders of Dissenting
Shares shall be made out of such escrow account, and no such payments shall be
made or otherwise funded by Parent.

or in the aggregate, a Company Material Adverse Effect.
 
    (b) Section 4.01 of the Company Disclosure Schedule sets forth, as of the

are no options, warrants or other rights, agreements, arrangements or
commitments of any character to which the Company is a party or by which the

in the aggregate, a Company Material Adverse Effect. Except as set forth in
Section 4.03 of the Company Disclosure Schedule, there are no material
outstanding contractual obligations of the Company or any Company Subsidiary to
provide funds to, or make any material investment (in the form of a loan,
capital contribution or otherwise) in, any Company Subsidiary or any other
person.

personal or mixed, reflected in the Company's consolidated financial statements
contained in the Company 1996 10-K as being owned by the Company and the Company
Subsidiaries as of the date thereof, other than (i) any properties or assets

organization, as the case may be, and has the requisite corporate power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as it is now being conducted, except

expected to have, individually or in the aggregate, a Parent Material Adverse
Effect. Parent, Merger Sub and each other Parent Subsidiary is duly qualified or
licensed to do business, and is in good standing (to the extent applicable), in
each jurisdiction where the character of the properties owned, leased or
operated by it or the nature of its business makes such qualification or
licensing necessary, except for such failures to be so qualified or licensed and
in good standing that could not reasonably be expected to have, individually or
in the aggregate, a Parent Material Adverse Effect.
 
    (b) SECTION 5.01 of the Parent Disclosure Schedule sets forth, as of the

Except as set forth in Section 5.01 of the Parent Disclosure Schedule, neither
Parent nor any Parent Subsidiary owns an equity interest in any partnership or
joint venture arrangement or other business entity that is material to the
financial condition, results of operations, business or prospects of Parent and
the Parent Subsidiaries, taken as a whole.

copies thereof. Parent has heretofore furnished the Company with true, complete
and correct copies of the articles of incorporation and bylaws of Merger Sub.
Such certificate or articles of incorporation, as the case may be, and bylaws
are in full force and effect. Neither Parent nor Merger Sub is in violation of
any of the provisions of its certificate or articles of incorporation, as the
case may be, or bylaws.

no material outstanding contractual obligations of Parent, Merger Sub or any
other Parent Subsidiary to provide funds to, or make any material investment (in
the form of a loan, capital contribution or otherwise) in, any Parent Subsidiary
or any other person.
 
    SECTION 5.04.  AUTHORITY RELATIVE TO THIS AGREEMENT.  Parent and Merger Sub
have all necessary corporate power and authority to execute and deliver this
Agreement, to perform their respective obligations hereunder and to consummate
the transactions contemplated hereby. The execution and delivery of this
Agreement by Parent and Merger Sub and the consummation by Parent and Merger Sub

consummate such transactions (other than the approval of this Agreement and the
Merger by the holders of a majority of the outstanding shares of Parent Common
Stock entitled to vote with respect thereto at the Parent Stockholders' Meeting,

<PAGE>
provision of the certificate or articles of incorporation, as the case may be,

any other Parent Subsidiary, (ii) assuming that all consents, approvals,
authorizations and permits described in Section 5.05(b) have been obtained and
all filings and notifications described in Section 5.05(b) have been made,
conflict with or violate any Law applicable to Parent or any other Parent
Subsidiary or by which any property or asset of Parent, Merger Sub or any other
Parent Subsidiary is bound or affected or (iii) except as set forth in Section
5.05(a) of the Parent Disclosure Schedule, result in any breach of or constitute
a default (or an event which with the giving of notice or lapse of time or both
could reasonably be expected to become a default) under, or give to others any
right of termination, amendment, acceleration or cancellation of, or result in
the creation of a lien or other encumbrance on any property or asset of Parent,
Merger Sub or any other Parent Subsidiary pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation, except, with respect to clauses (ii) and (iii), for
any such conflicts, violations, breaches, defaults or other occurrences which
could not reasonably be expected, individually or in the aggregate, (A) to have
a Parent Material Adverse Effect or (B) to prevent or materially delay the
performance by Parent or Merger Sub of its obligations pursuant to this
Agreement or the consummation of the Merger.
 
    (b) The execution and delivery of this Agreement by Parent and Merger Sub do

recordation of the Articles of Merger as required by the General Corporation Law
and (ii) where failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, could not reasonably be
expected, individually or in the aggregate, (A) to have a Parent Material
Adverse Effect or (B) to prevent or materially delay the performance by Parent
or Merger Sub of its obligations pursuant to this Agreement or the consummation
of the Merger.
 
    SECTION 5.06.  PERMITS; COMPLIANCE WITH LAWS.  (a) Parent, Merger Sub and
each other Parent Subsidiary is in possession of (i) all franchises, grants,
authorizations, licenses, establishment registrations, product listings,

identification and registration numbers, approvals and orders of any
Governmental Entity necessary for Parent, Merger Sub or any other Parent
Subsidiary to own, lease and operate its properties or to store, distribute and
market its products or otherwise to carry on its business as it is now being
conducted and (ii) agreements from all Federal, state, foreign and local
governmental agencies and accrediting and certifying organizations having
jurisdiction over such facility or facilities that are required to operate the
facility or facilities in the manner in which it or they are currently operated
and receive reimbursement for care provided to patients covered under the
Medicare program, any applicable Medicaid program or any comparable foreign
medical reimbursement program (collectively, the "PARENT PERMITS"), except where
the failure to have, or the suspension or cancellation of, any of the Parent
Permits could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect, and, as of the date of this
Agreement, no suspension or cancellation of any of the Parent Permits is pending
or, to the knowledge of Parent, threatened, except where the failure to have, or
the suspension or cancellation of, any of the Parent Permits could not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Without limiting the generality of the foregoing,
except as set forth in Section 5.06(a) of the Parent Disclosure Schedule, all of
Parent's facilities are certified for participation or enrollment in the
Medicare program, have a current and valid provider contract with the Medicare
program and are in substantial compliance with the conditions of participation
of such programs. None of Parent, Merger Sub or any other Parent Subsidiary is
in conflict with, or in default or violation of, (i) any Law applicable to
Parent, Merger Sub or any other Parent Subsidiary or by which any property or
asset of Parent, Merger Sub or any other Parent Subsidiary is bound or affected
or (ii) any Parent Permits, except in the case of
 
                                       23
<PAGE>
clauses (i) and (ii) for any such conflicts, defaults or violations that could
not reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Neither Purchaser nor any Purchaser Subsidiary has
received notice from the regulatory authorities that enforce the statutory or
regulatory provisions in respect of either the Medicare or the Medicaid program
of any pending or threatened investigations or surveys, and no such
investigations or surveys are pending or, to the knowledge of Parent, threatened
or imminent that could reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. Section 5.06(a) of the Parent
Disclosure Schedule sets forth, as of the date of this Agreement, all actions,
proceedings, investigations or surveys pending or, to the knowledge of Parent,
threatened against Parent or any Parent Subsidiary that could reasonably be
expected to result in (i) the loss or revocation of a Parent Permit necessary to
operate one or more facilities or for a facility to receive reimbursement under
the Medicare or Medicaid program or (ii) the suspension or cancellation of any
other Parent Permit, except any such Parent Permit where such suspension or
cancellation could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect. Except as set forth in Section
5.06(a) of the Parent Disclosure Schedule, since December 31, 1995, neither
Parent nor any Parent Subsidiary has received from any Governmental Entity any
written notification with respect to possible conflicts, defaults or violations
of Laws, except for written notices relating to possible conflicts, defaults or
violations that could not reasonably be expected to have, individually or in the
aggregate, a Parent Material Adverse Effect.
 
    (b) Parent and each Parent Subsidiary, as appropriate, is an approved
participating provider in and under all third party payment programs from which
it receives revenues. No action or investigation is pending, or to the best of
its knowledge, threatened to suspend, limit, terminate, condition, or revoke the
status of Parent or any Parent Subsidiary as a provider in any such program, and
neither Parent nor any Parent Subsidiary has been provided notice by any third
party payor of its intention to suspend, limit, terminate, revoke, condition or
fail to renew in whole or in part or decrease the amounts payable under any
arrangement with Parent or such Parent Subsidiary as a provider, which action,
investigation or proceeding would have, individually or in the aggregate, a
Parent Material Adverse Effect.
 
    (c) Parent and each Parent Subsidiary have filed on a timely basis all
claims, cost reports or annual filings required to be filed to secure payments
for services rendered by them under any third-party payment program from which
they receive or expect to receive revenues, except where the failure to file
such claim, report or other filing would not have, individually or in the
aggregate, a Parent Material Adverse Effect. Except as indicated in its
financial statements included in the Parent Reports, Parent or each Parent
Subsidiary, as applicable, has paid, or caused to be paid, all refunds,
discounts, adjustments, or amounts owing that have become due to such third
party payors pursuant to such claims, reports or filings, and neither Parent nor
any Parent Subsidiary has any knowledge or notice of any material changes
required to made to any cost reports, claims, or filings made by it for any
period or of any deficiency in such claim, report, or filing, except for changes
and deficiencies that in the aggregate would not have a Parent Material Adverse
Effect.
 
    SECTION 5.07.  SEC FILINGS; FINANCIAL STATEMENTS.  (a) Parent has timely
filed all forms, reports, statements and documents required to be filed by it
(A) with the SEC and the NYSE since December 31, 1994 through the date of this
Agreement (collectively and as amended, the "PARENT REPORTS") and (B) with any
other Governmental Entities, including, without limitation, state insurance and
health regulatory authorities. Except as is provided in the Parent Reports or as
disclosed in Section 5.07(a) of the Parent Disclosure Schedule, each Parent
Report (i) was prepared in accordance with the requirements of the Securities
Act, the Exchange Act or the NYSE, as the case may be, and (ii) did not at the
time it was filed contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements made therein, in the light of the circumstances under which
they were made, not misleading. Each form, report, statement and document
referred to in clause (B) of this paragraph was prepared in all material
respects in accordance with the requirements of applicable Law. Except as
disclosed in Section 5.07(a) of the Parent Disclosure Schedule, no Parent
Subsidiary is
 
                                       24
<PAGE>
subject to the periodic reporting requirements of the Exchange Act or required
to file any form, report or other document with the SEC, the NYSE, any other
stock exchange or any other comparable Governmental Entity.
 
    (b) Except as is provided in the Parent Reports or in Section 5.07(b) of the
Parent Disclosure Schedule, each of the consolidated financial statements
(including, in each case, any notes thereto) contained in the Parent Reports was
prepared in accordance with U.S. GAAP applied on a consistent basis throughout
the periods indicated (except as may be indicated in the notes thereto) and each
presented fairly, in all material respects, the consolidated financial position
of Parent and the consolidated Parent Subsidiaries as at the respective dates
thereof and for the respective periods indicated therein, except as otherwise
noted therein (subject, in the case of unaudited statements, to normal and
recurring year-end adjustments which were not and are not expected, individually
or in the aggregate, to have a Parent Material Adverse Effect).
 
    (c) Except as and to the extent set forth or reserved against on the
consolidated balance sheet of Parent and its Subsidiaries as reported in the
Parent Reports, including the notes thereto, or as disclosed in Section 5.07(c)
of the Parent Disclosure Schedule, none of Parent or any Parent Subsidiary has
any liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) that would be required to be reflected on a balance
sheet or in notes thereto prepared in accordance with U.S. GAAP, except for
liabilities or obligations incurred in the ordinary course of business
consistent with past practice since December 31, 1995 that have not had and
could not reasonably be expected to have, individually or in the aggregate, a
Parent Material Adverse Effect.
 
    SECTION 5.08.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since December 31,
1995, except as contemplated by or as disclosed in this Agreement, as set forth
in Section 5.08 of the Parent Disclosure Schedule or as disclosed in any Parent
Report filed since December 31, 1995, Parent and the Parent Subsidiaries have
conducted their businesses only in the ordinary course consistent with past
practice and, since such date, there has not been (i) any Parent Material
Adverse Effect, excluding any changes and effects resulting from changes in
economic, regulatory or political conditions or changes in conditions generally
applicable to the industries in which Parent and the Parent Subsidiaries are
involved, (ii) any event that could reasonably be expected to prevent or
materially delay the performance of its obligations pursuant to this Agreement
and the consummation of the Merger by Merger Sub, (iii) any material change by
Parent in its accounting methods, principles or practices or (iv) any
declaration, setting aside or payment of any dividend or distribution in respect
of the shares of Parent Common Stock or any redemption, purchase or other
acquisition of any of Parent's securities.
 
    SECTION 5.09.  EMPLOYEE BENEFIT PLANS; LABOR MATTERS.  (a) With respect to
each employee benefit plan, program, arrangement and contract (including,
without limitation, any "employee benefit plan", as defined in Section 3(3) of
ERISA) maintained or contributed to by Parent or any Parent Subsidiary, or with
respect to which Parent or any Parent Subsidiary could incur liability under
Section 4069, 4212(c) or 4204 of ERISA (the "PARENT BENEFIT PLANS"), Parent has
delivered or made available to the Company a true, complete and correct copy of

related to such Parent Benefit Plan, if a summary plan description is required

<PAGE>
With respect to the Parent Benefit Plans, no event has occurred and, to the
knowledge of Parent, there exists no condition or set of circumstances in
connection with which Parent or any Parent Subsidiary could be subject to any
liability under the terms of such Parent Benefit Plans, ERISA, the Code or any
other applicable Law which could reasonably be expected to have, individually or
in the aggregate, a Parent Material Adverse Effect.
 
    (c) Except as set forth in Section 5.09(c) of the Parent Disclosure
Schedule, neither Parent nor any Parent Subsidiary is a party to any collective
bargaining or other labor union contract applicable to persons employed by
Parent or any Parent Subsidiary and no collective bargaining agreement is being

there is no labor dispute, strike or work stoppage against Parent or any Parent
Subsidiary pending or, to the knowledge of Parent, threatened which may
interfere with the respective business activities of Parent or any Parent
Subsidiary, except where such dispute, strike or work stoppage could not
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. As of the date of this Agreement, to the knowledge of
Parent, none of Parent, any Parent Subsidiary, or any of their respective
representatives or employees has committed any unfair labor practice in
connection with the operation of the respective businesses of Parent or any
Parent Subsidiary, and there is no charge or complaint against Parent or any
Parent Subsidiary by the National Labor Relations Board or any comparable
Governmental Entity pending or threatened in writing, except where such unfair
labor practice, charge or complaint could not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect.

Agreement including, without limitation, any Cash Election) that could
reasonably be expected to prevent the Merger from constituting a transaction
qualifying under Section 368 of the Code. Parent is not aware of any agreement,
plan or other circumstances that could reasonably be expected to prevent the
Merger from so qualifying under Section 368 of the Code.
 
    SECTION 5.11.  CONTRACTS; DEBT INSTRUMENTS.  Except as disclosed in the
Parent Reports or in Section 5.11 of the Parent Disclosure Schedule, there is no
contract or agreement that is material to the business, financial condition or
results of operations of Parent and the Parent Subsidiaries taken as a whole
(each, a "PARENT MATERIAL CONTRACT"). Except as disclosed in the Parent Reports,
neither Parent nor any Parent Subsidiary is in violation of or in default under
(nor does there exist any condition which with the passage of time or the giving
of notice could reasonably be expected to cause such a violation of or default
under) any loan or credit agreement, note, bond, mortgage, indenture or lease,
or any other contract, license, agreement, arrangement or understanding to which
it is a party or by which it or any of its properties or assets is bound, except
for violations or defaults that could not reasonably be expected to have,

investigation. Except as disclosed to the Company, Parent is not aware of any
facts or circumstances which could reasonably be expected to result in the
denial of insurance coverage under policies issued to Parent and the Parent
Subsidiaries in respect of such suits, claims, actions, proceedings and
investigations, except in any case as could not reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect. Except as
disclosed in the Parent Reports, neither Parent nor any Parent Subsidiary is
 
                                       26

other proprietary rights and information used or held for use in connection with
the respective businesses of Parent and the Parent Subsidiaries as currently

any Parent Subsidiary is a party and pursuant to which (i) any third party is

Subsidiary and (ii) Parent or any Parent Subsidiary is authorized to use any
intellectual property rights (other than pursuant to shrink-wrap licenses and
software licenses) of a third party, and includes the identity of all parties

to facilitate, any inquiries or the making of any proposal or offer (including,
without limitation, any proposal or offer to its stockholders) that constitutes,
or may reasonably be expected to lead to, any Competing Transaction, or enter
into or maintain or continue discussions or negotiate with any person in

Rule 14e-2 promulgated under the Exchange Act with regard to a tender or
exchange offer not made in violation of this Section 6.05 or (ii) with regard to
such an offer, after receiving the advice of outside counsel to the effect that
the board of directors of the Company is required to do so in order to discharge
properly its fiduciary duties, considering, negotiating and approving and
recommending to the shareholders of the Company an unsolicited bona fide written
acquisition proposal which (A) was not received in violation of this Section

promptly, and in no event later than one day after receipt, if any proposal or
 
                                       31

elected by Parent prior to the Effective Time, Parent shall make such assumption
in such manner that Parent (i) is a corporation "assuming a stock option in a
transaction to which Section 424(a) applies" within the meaning of Section 424
of the Code or (ii) to the extent that Section 424 of the Code does not apply to

Code applicable to such Company Stock Option; and, if not so otherwise elected,
after the Effective Time, all references to the Company in the Company Stock
Plans and the applicable Company Stock Option agreements shall be deemed to
refer to Parent, which shall have assumed the Company Stock Plans as of the
Effective Time by virtue of this Agreement and without any further action on the

under this Agreement shall continue to have, and be subject to, the same terms
and conditions set forth in the applicable Company Stock Plan and the applicable
Company Stock Option as in effect immediately prior to the Effective Time,
except as otherwise provided in Section 3.05. Parent shall use all reasonable
efforts to ensure that Company Stock Options intended to qualify as incentive
stock options under Section 422 of the Code prior to the Effective Time continue
to so qualify after the Effective Time.
 
    (b) With respect to the Company Stock Plans, Parent shall take all corporate
action necessary or appropriate to, as soon as practicable after the Effective
Time, file a registration statement on Form S-8 (or any successor or other
appropriate form) with respect to the shares of Parent Common Stock subject to
such plan to the extent such registration statement is required under applicable
law in order for such shares of Parent Common Stock to be sold without
restriction, and Parent shall use its best efforts to maintain the effectiveness
of such registration statements (and maintain the current status of the
prospectuses contained therein) for so long as such benefits and grants remain
payable and such options under such plans remain outstanding.

    stockholders (including by taking no position with respect to the acceptance
    of such tender offer or exchange offer by its stockholders);

    or agreement on the part of the Company set forth in this Agreement, or if
    any representation or warranty of the Company shall have become untrue,
    incomplete or incorrect, in either case such that the conditions set forth
    in Section 8.03 would not be satisfied (a "TERMINATING COMPANY BREACH");
    PROVIDED, HOWEVER, that if such

    Terminating Company Breach is curable by the Company through the exercise of
    its reasonable efforts within 30 days and for so long as the Company
    continues to exercise such reasonable efforts, Parent may not terminate this
    Agreement under this Section 9.01(g); and PROVIDED FURTHER that the
    preceding proviso shall not in any event be deemed to extend any date set
    forth in paragraph (b) of this Section 9.01;
 
        (h) by the Company, upon breach of any representation, warranty,
    covenant or agreement on the part of Parent set forth in this Agreement, or
    if any representation or warranty of Parent shall have become untrue,
    incomplete or incorrect, in either case such that the conditions set forth
    in Section 8.02 would not be satisfied (a "TERMINATING PARENT BREACH");
    PROVIDED, HOWEVER, that if such Terminating Parent Breach is curable by
    Parent through the exercise of its reasonable efforts within 30 days and for
    so long as Parent continues to exercise such reasonable efforts, the Company
    may not terminate this Agreement under this Section 9.01(h); and PROVIDED
    FURTHER that the preceding proviso shall not in any event be deemed to
    extend any date set forth in paragraph (b) of this Section 9.01; or
 
        (i) by Parent, if (x) (A) any Governmental Order, writ, injunction or
    decree determining the Stockholders Stock Option and Proxy Agreement invalid

    SECTION 10.01.  NON-SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The

Effective Time or upon the termination of this Agreement pursuant to Section
9.01, as the case may be. Each party agrees that, except for the representations
and warranties contained in this Agreement and the Parent Disclosure Schedule

party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a mutually acceptable manner to the fullest
extent permitted by applicable Law in order that the Merger may be consummated

parties hereto and their respective successors and permitted assigns.
Notwithstanding anything contained in this Agreement to the contrary, other than

IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

Agreement are included for convenience of reference only and shall not affect in
any way the meaning or interpretation of this Agreement.
 
    SECTION 10.09.  COUNTERPARTS.  This Agreement may be executed and delivered

grant Parent an option to purchase Stockholder's Shares and proxies to vote
Stockholder's Shares;
 
    NOW, THEREFORE, in consideration of the premises and of the mutual
agreements and covenants set forth herein and in the Merger Agreement, the
parties hereto agree as follows:
 
                                   ARTICLE I
                                  THE OPTIONS
 
    SECTION 1.01.  GRANT OF OPTIONS.  Stockholder hereby grants to Parent an
irrevocable option (each, an "OPTION") to purchase Stockholder's Shares at (i) a
price per share of Company Common Stock equal to $8.50 (the "COMMON PURCHASE
PRICE") and (ii) a price per share of A Preferred equal to $4.00 (the "A
PURCHASE PRICE" and, together with the Common Purchase Price, the "PURCHASE
PRICE"). Each Option shall expire if (i) such Option is not exercised prior to
the close of business on the 120th day following termination of the Merger
Agreement or (ii) if the Merger Agreement is terminated pursuant to Section
9.01(c) thereof.
 
    SECTION 1.02.  EXERCISE OF OPTIONS.  (a) Provided that (i) to the extent
necessary, any applicable waiting periods (and any extension thereof) under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976 and the rules and
regulations promulgated thereunder (the "HSR ACT") with respect to the exercise
of an Option shall have expired or been terminated and (ii) no preliminary or
permanent injunction or other order, decree or ruling issued by any court or
governmental or regulatory authority, domestic or foreign, of competent
jurisdiction prohibiting the exercise of an Option or the delivery of Shares
shall be in effect, Parent may exercise any or all of the Options at any time
following the earlier of (i) the termination of the Merger Agreement (other than
a termination pursuant to Section 9.01(c) thereof) and (ii) the first occurrence
of a Competing Transaction until the expiration of such Options. In the event
that Parent wishes to exercise an Option, Parent shall give written notice (the
date of such notice being herein called the "NOTICE DATE"), to Stockholder
specifying a place and date (not later than ten Business Days (as defined below)
and not earlier than three Business Days following the Notice Date) for closing
such purchase (the "CLOSING"). For the purposes of this Agreement, the term
"BUSINESS DAY" shall mean any day on which
 
                                       1
<PAGE>
banks are not required or authorized by law, regulation or executive order to
close in New York, New York.
 
    (b) If Parent shall exercise any Option in accordance with the terms of this
Agreement, and without additional consideration, Stockholder shall execute and
deliver further transfers, assignments, endorsements, consents and other
instruments as Parent may reasonably request for the purpose of effectively
carrying out the transactions contemplated by this Agreement and the Merger
Agreement, including the transfer of any and all of Stockholder's Shares Parent
and the release of any and all liens, claims and encumbrances covering such
Shares.
 
    SECTION 1.03.  PAYMENT FOR AND DELIVERY OF CERTIFICATES.  At the Closing,
(a) Parent shall pay the aggregate Purchase Price for the Shares being purchased
from Stockholder by (i) wire transfer in immediately available funds of the
total amount of the Purchase Price for such Shares to an account designated by
Stockholder by written notice to Parent or (ii) delivery of that number of
shares of Parent Common Stock equal to the quotient of the total amount of the
Purchase Price and the Closing Date Market Price (determined as if the Effective
Time had occurred on the Notice Date), (b) Stockholder shall deliver to Parent a
certificate or certificates evidencing Stockholder's Shares, and Stockholder
agrees that such Shares shall be transferred free and clear of all liens and (c)
in the event that Parent has elected to pay the exercise price with shares of
Parent Common Stock, Parent shall deliver to Stockholder a certificate or
certificates evidencing such shares, and Parent agrees that such shares of
Parent Common Stock shall be transferred free and clear of all liens. All such
certificates representing Shares shall be duly endorsed in blank, or with
appropriate stock powers, duly executed in blank, attached thereto, in proper
form for transfer, and with all applicable taxes paid or provided for.
 
                                   ARTICLE II
                         TRANSFER AND VOTING OF SHARES
 
    SECTION 2.01.  TRANSFER OF SHARES.  During the term of the Options, and
except as otherwise provided herein, Stockholder shall not (a) sell, pledge or
otherwise dispose of any of its Shares, (b) deposit its Shares into a voting
trust or enter into a voting agreement or arrangement with respect to such
Shares or grant any proxy with respect thereto or (c) enter into any contract,
option or other arrangement or undertaking with respect to the direct or
indirect acquisition or sale, assignment, transfer or other disposition of any
the Company Capital Stock.
 
    SECTION 2.02.  VOTING OF SHARES; FURTHER ASSURANCES.  (a) Stockholder, by
this Agreement, with respect to those Shares that it owns of record, does hereby
constitute and appoint Parent, or any nominee of Parent, with full power of
substitution, during and for the term of the Option granted by Stockholder
hereunder (or, following termination of the Merger Agreement, during such
periods as the Options are exercisable), as its true and lawful attorney and
proxy, for and in its name, place and stead, to vote each of such Shares as its
proxy, at every annual, special or adjourned meeting of the stockholders of the
Company (including the right to sign its name (as stockholder) to any consent,
certificate or other document relating to the Company that the law of the State
of Colorado may permit or require) (i) in favor of the adoption of the Merger
Agreement and approval of the Merger and the other transactions contemplated by
the Merger Agreement, (ii) against any proposal for any recapitalization,
merger, sale of assets or other business combination between the Company and any
person or entity (other than the Merger) or any other action or agreement that
would result in a breach of any covenant, representation or warranty or any
other obligation or agreement of the Company under the Merger Agreement or which
could result in any of the conditions to the Company's obligations under the
Merger Agreement not being fulfilled, and (iii) in favor of any other matter
relating to consummation of the transactions contemplated by the Merger
Agreement. Stockholder further agrees to cause the Shares owned by it
beneficially to be voted in accordance with the foregoing. Stockholder
acknowledges receipt and review of a copy of the Merger Agreement.

prevent or delay the performance by Stockholder of its obligations under this
Agreement.

owner of its Shares free and clear of any proxy or voting restriction other than

                                  WITNESSETH:
 
    WHEREAS, Parent, Merger Sub, and the Company desire to amend the Merger
Agreement as provided in Amendment No. 2 thereto dated of even date herewith;
and
 
    WHEREAS, in connection therewith Parent and Stockholder desire to amend the
Agreement as provided herein.
 
    NOW, THEREFORE, in consideration of the foregoing and the representations,
warranties, covenants and agreements set forth herein, and other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, and intending to be legally bound hereby, the parties hereto
hereby agree as follows:
 
    SECTION 1:  AMENDMENT TO AGREEMENT.  The Agreement is hereby amended as
follows:
 
    (a) Section 1.01 of the Agreement is hereby amended by (i) replacing the
phrase "120th" with the phrase "14th" therein and (ii) adding the following
phrase at the end thereof: "or terminated or terminable pursuant to Section
9.01(h) thereof."
 
    (b) The following is hereby inserted as a new Article V thereto and the
succeeding Articles and Section are hereby appropriately renumbered:
 
                                   ARTICLE V
                              REGISTRATION RIGHTS
 
    SECTION 5.01.  SHELF REGISTRATION.  (a) In the event that Parent pays for
the Shares being purchased by delivery of shares of Parent Common Stock, Parent
shall, within three months following the Closing, file with the Securities and
Exchange Commission (the "COMMISSION") a shelf registration statement on an
appropriate form under Rule 415 under the Securities Act, or any similar rule
that may be adopted by the Commission (a "SHELF REGISTRATION STATEMENT"),
relating to the resale of the Parent Shares by the Stockholder from time to time
in accordance with the methods of distribution set forth in such Shelf
Registration Statement and shall use its best efforts to cause such Shelf
Registration Statement to be declared effective under the Securities Act as soon
as practicable thereafter; PROVIDED, HOWEVER, that Stockholder shall not be
entitled to have the Parent Shares held by it covered by such Shelf Registration
Statement unless Stockholder is in compliance with Section 5.02(f) hereof.
 
    (b) Parent shall use its best efforts to keep the Shelf Registration
Statement continuously effective in order to permit the prospectus forming part
thereof to be usable by the Stockholders until the earliest to occur of the
following: (A) the two year anniversary of the Closing; (B) the earliest time at
which all the Parent Shares covered by the Shelf Registration Statement have
been sold pursuant to the Shelf Registration Statement; and (C) the earliest
time at which, in the written opinion of independent counsel to Parent, all
outstanding Parent Shares held by persons that are not affiliates of Parent may
be resold without registration under the Securities Act pursuant to Rule 144(k)
under the Securities Act or any successor provision thereto (in any such case,
such period being called the "EFFECTIVENESS PERIOD"). Parent shall be deemed not
to have used its best efforts to keep the Shelf Registration Statement effective
during the requisite period if Parent voluntarily takes any action that would
result in Stockholders of Parent Shares
 
                                       1
<PAGE>
covered thereby not being able to offer and sell any such Parent Shares during
that period, unless (i) such action is required by applicable law, (ii) the
continued effectiveness of the Shelf Registration Statement would require Parent
to disclose a material financing, acquisition or other corporate transaction,
and the Board of Directors shall have determined in good faith that such
disclosure is not in the best interests of Parent and its stockholders, or (iii)
the Board of Directors shall have determined in good faith that there is a valid
business purpose for such suspension.
 
    SECTION 5.02.  REGISTRATION PROCEDURES.  In connection with any Shelf
Registration Statement, the following provisions shall apply:
 
        (a) Parent shall take such action as may be necessary so that (i) any
    Shelf Registration Statement and any amendment thereto and any prospectus
    forming part thereof and any amendment or supplement thereto (and each
    report or other document incorporated therein by reference in each case)
    complies in all material respects with the Securities Act and the Exchange
    Act, and the respective rules and regulations thereunder, (ii) any Shelf
    Registration Statement and any amendment thereto does not, when it becomes
    effective, contain an untrue statement of a material fact or omit to state a
    material fact required to be stated therein or necessary to make the
    statements therein not misleading and (iii) any prospectus forming part of
    any Shelf Registration Statement, and any amendment or supplement to such
    prospectus, does not include an untrue statement of a material fact or omit
    to state a material fact necessary in order to make the statements, in the
    light of the circumstances under which they were made, not misleading.
 
        (b) Parent shall advise the Stockholder:
 
            (i) when a Shelf Registration Statement and any amendment thereto
       has been filed with the Commission and when the Shelf Registration
       Statement or any post-effective amendment thereto has become effective;
 
            (ii) upon the issuance by the Commission of any stop order
       suspending effectiveness of the Shelf Registration Statement or the
       initiation of any proceedings for that purpose;
 
           (iii) upon the receipt by Parent of any notification with respect to
       the suspension of the qualification of the securities included therein
       for sale in any jurisdiction or the initiation of any proceeding for such
       purpose; and
 
            (iv) upon the happening of any event that requires the making of any
       changes in the Shelf Registration Statement or the prospectus so that, as
       of such date, the Shelf Registration Statement and the prospectus do not
       contain an untrue statement of a material fact and do not omit to state a
       material fact required to be stated therein or necessary to make the
       statements therein (in the case of the prospectus, in light of the
       circumstances under which they were made) not misleading (which advice
       shall be accompanied by an instruction to suspend the use of the
       prospectus until the requisite changes have been made).
 
        (c) Parent shall, during the Effectiveness Period, deliver to
    Stockholder with respect to a Shelf Registration Statement, without charge,
    as many copies of the prospectus (including each preliminary prospectus)
    included in such Shelf Registration Statement and any amendment or
    supplement thereto as Stockholder may reasonably request; and Parent
    consents (except during the continuance of any event described in Section
    5.02(b)(iv)) to the use of the prospectus or any amendment or supplement
    thereto by Stockholder in connection with the offering and sale of the
    Parent Shares covered by the prospectus or any amendment or supplement
    thereto during the Effectiveness Period.
 
        (d) Prior to any offering of Parent Shares pursuant to any Shelf
    Registration Statement, Parent shall register or qualify or cooperate with
    the Stockholder and its counsel in connection with the registration or
    qualification of such Parent Shares for offer and sale under the securities
    or blue sky laws of such jurisdictions as any such Stockholders reasonably
    request in writing and do any and all
 
                                       2
<PAGE>
    other acts or things necessary or advisable to enable the offer and sale in
    such jurisdictions of the Parent Shares covered by such Shelf Registration
    Statement; PROVIDED, HOWEVER, that in no event shall Parent be obligated to
    (i) qualify as a foreign corporation or as a dealer in securities in any
    jurisdiction where it would not otherwise be required to so qualify but for
    this Section 5.02(d), (ii) file any general consent to service of process in
    any jurisdiction where it is not as of the date hereof then so subject or
    (iii) subject itself to taxation in any jurisdiction if it is not so
    subject.
 
        (e) Upon the occurrence of any event contemplated by Section 5.02(b)(iv)
    above, Parent shall promptly prepare a post-effective amendment to any Shelf
    Registration Statement or an amendment or supplement to the related
    prospectus or file any other required document so that, as thereafter
    delivered to purchasers of the Parent Shares included therein, the
    prospectus will not include an untrue statement of a material fact or omit
    to state any material fact necessary to make the statements therein, in the
    light of the circumstances under which they were made, not misleading. If
    Parent notifies the Stockholder of the occurrence of any event contemplated
    by Section 5.02(b)(iv) above, the Stockholder shall suspend the use of the
    prospectus until the requisite changes to the prospectus have been made.
 
        (f) Parent may require Stockholder with respect to a Shelf Registration
    Statement to furnish to Parent such information regarding the Stockholder
    and the distribution of Parent Shares held by the Stockholder as may be
    required by applicable law or regulation for inclusion in such Shelf
    Registration Statement and Parent may exclude from such registration the
    Parent Shares of any Stockholder that fails to furnish such information
    within a reasonable time after receiving such request.
 
        (g) Parent will use its best efforts to cause the Parent Shares to be
    listed on the New York Stock Exchange or other stock exchange or trading
    system on which the Parent Common Stock primarily trades on or prior to the
    effective date of any Shelf Registration Statement hereunder."

Albuquerque, New Mexico 87109
Attention: Robert F. Murphy
 
                              AFFILIATE AGREEMENT
 
Ladies and Gentlemen:
 
    Reference is made to the Agreement and Plan of Merger and Reorganization,
dated as of February 17, 1997 (the "Merger Agreement"; capitalized terms used
and not otherwise defined herein are used herein as defined in the Merger
Agreement), among Sun Healthcare Group Inc., a corporation organized under the
laws of the State of Delaware ("Parent"), Nectarine Acquisition Corporation, a
corporation organized under the laws of the State of Nevada ("Merger Sub") and a
direct wholly owned subsidiary of Parent, and Contour Medical, Inc., a
corporation organized under the laws of the State of Nevada (the "Company").
 
    Pursuant to the terms of the Merger Agreement, at the Effective Time,
outstanding shares of Company Capital Stock will be converted into and become
exchangeable for shares of Parent Common Stock and/or cash on the basis set
forth in the Merger Agreement.
 
    The undersigned has been advised that as of the date hereof [it ] [he] [she]
may be deemed to be an "affiliate" of the Company, as such term is defined for
purposes of paragraphs (c) and (d) of rule 145 ("Rule 145") of the rules and
regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act").
 
    The undersigned understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, stockholders of
Parent, the Company and other stockholders of the Company and their respective
counsel and accounting firms.
 
    The undersigned hereby represents and warrants to and agrees with Parent
that:
 
        1.  The undersigned has full power and authority to execute and deliver
    this letter agreement and to make the representations and warranties set
    forth herein and to perform [its] [his] [her] obligations hereunder;
 
        2.  The undersigned has carefully read this letter agreement and the
    Merger Agreement and, to the extent the undersigned felt necessary,
    discussed the requirements of such documents and other applicable
    limitations upon [its] [his] [her] ability to sell, transfer, pledge or
    otherwise dispose of Parent Common Stock with [its] [his] [her] counsel or
    counsel for the Company;
 
        3.  The undersigned is the beneficial owner of (has sole or shared
    voting or investment power with respect to) the shares of Company Capital
    Stock and options or warrants to purchase Company Capital Stock specified
    beneath [its] [his] [her] name on the signature page hereto (the "Company
    Securities"). Except for the Company Securities, the undersigned does not
    own beneficially any shares of Company Capital Stock or any other equity
    securities of the Company or any options, warrants or other rights to
    acquire any equity securities of the Company;
 
                                       1
<PAGE>
        4.  The undersigned will not make any sale, transfer, pledge or other
    disposition of Parent Common Stock in violation of the Securities Act or the
    Rules and Regulations;
 
        5.  The undersigned has been advised that the issuance of Parent Common
    Stock to the undersigned in connection with the Merger has been or will be
    registered with the Commission under the Securities Act on a Registration
    Statement on Form S-4. However, the undersigned has also been advised that,
    since at the time the Merger was or will be submitted for a vote of the
    stockholders of the Company the undersigned may be deemed to be or have been
    an affiliate of the Company and the distribution by the undersigned of any
    Parent Common Stock has not been registered under the Securities Act, the
    undersigned may not sell, transfer, pledge or otherwise dispose of Parent
    Common Stock issued to [it] [him] [her ] in the Merger unless (i) such sale,
    transfer, pledge or other disposition has been registered under the
    Securities Act, (ii) such sale, transfer, pledge or other disposition is
    made in conformity with the volume and other limitations of Rule 145 or
    (iii) in the opinion of counsel reasonably acceptable to Parent (it being
    understood that the law firms of Rogers & Hardin and Shearman & Sterling are
    deemed to be reasonably satisfactory to Parent), such sale, transfer, pledge
    or other disposition is otherwise exempt from registration under the
    Securities Act;
 
        6.  The undersigned understands that, except as provided in the Merger
    Agreement, Parent is under no obligation to register the sale, transfer,
    pledge or other disposition of Parent Common Stock by the undersigned or on
    [its] [his] [her] behalf under the Securities Act or to take any other
    action necessary in order to make compliance with an exemption from such
    registration available;
 
        7.  The undersigned also understands that stop transfer instructions
    will be given to Parent's transfer agents with respect to Parent Common
    Stock issued to [it][him] [her] and that there will be placed on the
    certificates for Parent Common Stock issued to [it] [him] [her], or any
    substitutions therefor, a legend stating in substance:
 
           "THE SECURITIES EVIDENCED BY THIS CERTIFICATE WERE ISSUED IN A
       TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
       1933, AS AMENDED, APPLIES. THE SECURITIES EVIDENCED BY THIS CERTIFICATE
       HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
       ANY STATE SECURITIES LAWS, AND MAY NOT BE TRANSFERRED, SOLD, ASSIGNED,
       PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF, AND NO REGISTRATION OF
       TRANSFER OF SUCH SECURITIES WILL BE MADE ON THE BOOKS OF THE ISSUER,
       UNLESS SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER
       DISPOSAL IS MADE IN CONNECTION WITH AN EFFECTIVE REGISTRATION STATEMENT
       UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND ANY APPLICABLE STATE
       SECURITIES LAWS OR IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF SUCH
       ACT, THE RULES AND REGULATIONS IN EFFECT THEREUNDER AND ANY APPLICABLE
       STATE SECURITIES LAWS";
 
        8.  The undersigned also understands that, unless the sale, transfer,
    pledge or other disposition by [it] [him] [her] of Parent Common Stock
    issued to [it] [him ] [her] has been registered under the Securities Act or
    is a sale made in conformity with the provisions of Rule 145, Parent
    reserves the right to put the following legend on the certificates issued to
    any transferee of the undersigned:
 
           "THE SECURITIES EVIDENCED BY THIS CERTIFICATE WERE ACQUIRED FROM A
       PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145
       PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIES, AND
       WERE NOT ACQUIRED BY THE HOLDER WITH A VIEW TO, OR FOR RESALE IN
       CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE
       SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES EVIDENCED BY THIS
       CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE

       MADE ON THE BOOKS OF THE ISSUER, UNLESS SUCH TRANSFER, SALE, ASSIGNMENT,

       AMENDED, AND ANY APPLICABLE STATE SECURITIES LAWS OR IS EXEMPT FROM THE
       REGISTRATION REQUIREMENTS OF SUCH ACT, THE RULES AND REGULATIONS IN
       EFFECT THEREUNDER AND ANY APPLICABLE STATE SECURITIES LAWS";
 
        9.  Except to the extent written notification to the contrary is
    received by Parent from the undersigned prior to the Merger, the
    representations contained herein will be true, complete and correct at all
    times from the date hereof through the Closing Date; and
 
        10. The undersigned currently intends to vote all Company Capital Stock
    held by [it] [him] [her] in favor of the Merger.

warranties, covenants and agreements set forth herein, and other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, and intending to be legally bound hereby, the parties hereto
hereby agree as follows:
 
    SECTION 1.  AMENDMENTS TO MERGER AGREEMENT.  The Merger Agreement is hereby
amended as follows:
 
        (a) Section 6.06 of the Merger Agreement is hereby amended and restated
    in its entirety to read as follows:
 
           "SECTION 6.06.  LETTERS OF ACCOUNTANTS.  At the written request of
       Parent, each of the Company and/or Parent shall use all reasonable
       efforts to cause to be delivered to the other "comfort" letters of their
       respective independent public accountants, each such letter dated and
       delivered as of the date the Registration Statement shall have become
       effective and as of the Effective Time, and addressed to Parent and the
       Company, respectively, in form and substance reasonably satisfactory to
       the recipient thereof and reasonably customary in scope and substance for
       letters delivered by independent public accountants in connection with
       mergers such as the Merger contemplated hereby."
 
        (b) Article VI of the Merger Agreement is hereby amended by adding the

       in the Company 1996 10-K; PROVIDED, HOWEVER, that the Company shall not
       be required under this Section 6.10(a) to pay any amounts claimed by
       Coopers & Lybrand L.L.P. which, in the Company's good faith exercise of
       its reasonable judgment, are subject to valid claims of set-off or other
       defenses or counterclaims.
 
           (b) The Company shall use its best efforts to cause Coopers & Lybrand
       L.L.P. to make available to Arthur Andersen LLP copies of all materials
       in Coopers & Lybrand L.L.P.'s possession relating to Coopers & Lybrand
       L.L.P.'s audit of the Company's financial statements for the year ended
       June 30, 1997, including all work papers, computer files and other

<PAGE>
       Company shall not be required under this Section 6.10(b) to pay any
       amounts claimed by Coopers & Lybrand L.L.P. which, in the Company's good
       faith exercise of its reasonable judgment, are subject to valid claims of
       set-off or other defenses or counterclaims."
 
        (c) Section 9.01(b) of the Merger Agreement is hereby amended and
    restated in its entirety to read as follows:
 
        "(b)  by either Parent or the Company, if the Effective Time shall not
    have occurred on or before November 30, 1997; PROVIDED, HOWEVER, that in the

    such time (A) the condition specified in Section 8.01(a) shall have been
    satisfied, (B) neither the Company Stockholders' Meeting nor, if applicable,
    the Parent Stockholders' Meeting, shall have been held, and (C) neither

    or (ii) solely due to the failure to satisfy the condition specified in
    Section 8.01(d) or 8.01(e), then such date may be extended, at the option of
    Parent, until December 31, 1997; and PROVIDED, FURTHER, that the right to
    terminate this Agreement under this Section 9.01(b) shall not be available
    to any party whose failure to fulfill any obligation under this Agreement
    shall have caused, or resulted in, the failure of the Effective Time to

amended as follows:
 
        (a) Section 3.01 of the Agreement shall be amended (i) by deleting the
    first parenthetical phrase of Section 3.01(a) and adding the following
    parenthetical phrase in place thereof: "other than any shares of Company
    Common Stock to be cancelled pursuant to Section 3.01(c), any shares of
    Company Common Stock to be treated in accordance with Section 3.01(e) and
    any Dissenting Shares)"; and (ii) by adding the following new Section
    3.01(e) thereto: "(e) Each share of Company Common Stock issued and
    outstanding immediately prior to the Effective Time and owned by Principal
    Stockholder shall remain issued and outstanding; PROVIDED, HOWEVER, that if
    at the time the Articles of Merger are filed with the Secretary of State of
    Nevada either (i) articles of merger with respect to the RCA Merger have not
    been filed so as to cause the RCA Merger to occur immediately after the
    Merger or (ii) Parent has not undertaken to contribute to Principal
    Stockholder all shares of Company Capital Stock obtained by Parent pursuant
    to the Merger, then the Principal Stockholder Shares shall not be treated in
    accordance with this Section 3.01(e) but instead shall be treated in
    accordance with Section 3.01(a)."
 
        (b) Section 9.01(b) of the Merger Agreement is hereby amended and
    restated in its entirety to read as follows:
 
           "(b)  by either Parent or the Company, if the Effective Time shall
       not have occurred on or before March 31, 1998; PROVIDED, HOWEVER, that
       the right to terminate this Agreement under this Section 9.01(b) shall
       not be available to any party whose failure to fulfill any obligation
       under this Agreement shall have caused, or resulted in, the failure of
       the Effective Time to occur on or before such date."

February 17, 1997
 
The Board of Directors
Sun Healthcare Group
 
Attention:  Andy Turner
        President and CEO
 
Ladies and Gentlemen:
 
    You have requested our opinion as to the fairness, from a financial point of
view, to Sun Healthcare Group, Inc. (the "Company") of the consideration
proposed to be paid by the Company in connection with the proposed merger (the
"Merger") of a wholly-owned subsidiary of the Company ("the Merger Subsidiary")
with Contour Medical, Inc. (the "Seller"). Pursuant to the Agreement and Plan of
Merger and Reorganization dated as of February 17, 1997 (the "Agreement"), among
the Merger Subsidiary, the Seller, and the Company, the Seller will become a
wholly-owned subsidiary of the Company, and the Company will pay for each share
of Common Stock, par value $0.001 per share, of the Seller consideration equal
to $8.50 in cash or stock at the Company's option and will pay cash or issue
common shares at the discretion of the Company with respect to Class A Preferred
Stock as provided in more detail in the Agreement.
 
    In arriving at our opinion, we have reviewed (i) the Agreement; (ii) certain
publicly available information concerning the business of the Seller and of
certain other companies engaged in businesses comparable to those of the Seller,
and the reported market prices for certain other companies' securities deemed
comparable; (iii) publicly available terms of certain transactions involving
companies comparable to the Seller and the consideration received for such
companies; (iv) current and historical market prices of the Common Stock of the
Seller; (v) the audited financial statements of the Company for the fiscal year
ended December 31, 1994 and December 31, 1995 and the Seller for the fiscal year
ended June 30, 1995 and June 30, 1996 and the unaudited financial statements of
the Seller and the Company for the period ended September 30, 1996; (vi) certain
agreements with respect to outstanding indebtedness or obligations of the
Company and the Seller; (vii) certain internal financial analyses and forecasts
prepared by the Seller, the Company, and their respective managements; and
(viii) the terms of other business combinations that we deemed relevant.
 
    In addition, we have held discussions with certain members of the management
of the Company and the Seller with respect to certain aspects of the Merger, and
the past and current business operations of the Company and the Seller, the
financial condition and future prospects and operations of the Company and the
Seller, the effects of the Merger on the financial condition and future
prospects of the Company and the Seller, and certain other matters we believed
necessary or appropriate to our inquiry. We have visited certain representative
facilities of the Seller, and reviewed such other financial studies and analyses
and considered such other information as we deemed appropriate for the purposes
of this opinion.
 
    In giving our opinion, we have relied upon and assumed, without independent
verification, the accuracy and completeness of all information that was publicly
available or was furnished to us by the Company and the Seller or otherwise
reviewed by us, and we have not assumed any responsibility or liability
therefor. We have not conducted any valuation or appraisal of any assets or
liabilities, nor have any such valuations or appraisals been provided to us. In
relying on financial analyses and forecasts provided to us, we have assumed that
they have been reasonably prepared based on assumptions reflecting the best
currently available estimates and judgements by management as to the expected
future results of operations and financial condition of the Company and the
Seller. We have relied as to all legal matters relevant to rendering our opinion
upon the advice of counsel. We have also considered the material
<PAGE>
synergies that the management of the company believes can be attained as a
result of the Merger. We have assumed that these synergies reflect the best
currently available estimates of management of the Company and will be readily
achieved. We have also considered the fact that the Company is purchasing
Retirement Care Associates, which owns the majority interest in the Seller.
 
    Our opinion is necessarily based on economic, market and other conditions as
in effect on, and the information made available to us as of, the date hereof.
It should be understood that subsequent developments may affect this opinion and

We are expressing no opinion herein as to the price at which the Company's stock
will trade at any future time.

matters. In the ordinary course of their businesses, our affiliates may actively
trade the debt and equity securities of the Company or the Seller for their own
account or for the accounts of customers and, accordingly, they may at any time

    On the basis of and subject to the foregoing, it is our opinion as of the
date hereof that the consideration to be paid by the Company in the proposed
Merger is fair, from a financial point of view, to the Company.

Board of Directors

St. Petersburg, Florida 33716
 
Gentlemen:
 
    You have requested the opinion of Sterne, Agee & Leach, Inc. ("SALI") as to
the fairness, from a financial point of view, to Contour Medical, Inc.
("Contour"), of the consideration to be paid by Sun Healthcare Group, Inc.
("Sun") in connection with the proposed merger (the "Contour Merger") of
Nectarine Acquisition Corporation ("Contour Merger Sub"), a direct wholly-owned
subsidiary of Sun, with and into Contour pursuant to the Agreement and Plan of
Merger and Reorganization, dated as of February 17, 1997, by and among Contour,
Contour Merger Sub and Sun. In the Contour Merger, each share of common stock of
Contour ("Contour Common Stock") issued and outstanding immediately prior to the
effectiveness of the Contour Merger shall be converted into the right to receive
$8.50 per share, in cash or Sun's common stock or a combination thereof, at
Sun's choice (the "Merger Consideration").
 
    SALI is a registered broker/dealer, with expertise including retail and
institutional brokerage; investment banking and underwriting; secondary trading
of corporate, municipal, and government securities; and market making in
over-the-counter stocks. We have acted as financial advisor to the Board of
Directors of Contour in connection with the Contour Merger and will receive a
fee for our services, part of which has been paid as a retainer with the
remainder to be paid with the completion of of our opinion. In addition, Contour
has agreed to indemnify SALI against certain liabilities. The only relationship
between SALI and Contour and any of its affiliates that has existed at any time
over the prior two years has been SALI's preliminary discussion leading to this
engagement.

    In arriving at our opinion we considered the nature of the business and
history of the enterprise, the economic outlook in general, the outlook for the
health care industry and the medical products segment in particular, Contours
earnings are cash flows for the last four years, the outlook for future
earnings, the book value of Contour Common Stock, Contours' financial condition,
its expense paying capacity, past transactions in Contour Common Stock, sales of
comparable companies, and prices at which other public companies in related
lines of business are selling. We had discussions with management of Contour
concerning its financial condition, business, operations, and prospects and
conducted such other analyses as we deemed relevant to form a basis for our
opinion.
 
    We have relied on, and assumed the accuracy and completeness of, the
information provided by Contour, its employees, attorneys, agents, and
representatives, including any appraisals given to us. We did not attempt any
independent verification thereof. We did not perform any audit of the
information submitted, including any financial, environmental, or real estate
information. We in all cases assumed, but did not verify, the genuineness of all
signatures, the authenticity of all original documents submitted, the conformity
of all copies submitted to the originals, due authorization, execution, and
delivery of all documents and the accuracy of all information supplied and
statements made. We assumed that Contour has complied with or will in a timely
fashion comply with all applicable laws, rules, and regulations. We further
assumed that Contour has provided all relevant material information concerning
its historical and future business operations and financial condition.
 
    Our opinion is based on economic, industry, market, and other conditions as
in effect on, and the information made available to us as of, the date of such
opinion. Our opinion does not address Contour's underlying business decision to
effect the Contour Merger or constitute a recommendation to any holder of
Contour Common Stock as to how such holder should vote with respect to the
Contour Merger. Subsequent developments may affect our opinion, and we do not
have any obligation to update, revise, or reaffirm such opinion. We express no
opinion as to the price at which Sun's Common Stock will trade at any future
time.
 
    Based on our analysis of the factors deemed relevant, it is our opinion that
the Merger Consideration is fair from a financial point of view to the
stockholders of Contour.
 
                                          Very truly yours,

dissenters' rights that the action was taken and send them the dissenter's
notice described in NRS 92A.430.

<PAGE>
    person asserting dissenter's rights certify whether or not he acquired
    beneficial ownership of the shares before that date;
 
        (d) Set a date by which the subject corporation must receive the demand

    1.  Except as otherwise provided in NRS 92A.470, within 30 days after

    or
 
        (b) At the election of any dissenter residing or having its registered

        (c) An explanation of how the interest was calculated;
 
                                       4
<PAGE>
        (d) A statement of the dissenter's rights to demand payment under NRS
    92A.480; and
 
        (e) A copy of NRS 92A.300 to 92A.500, inclusive.
 
92A.470. PAYMENT FOR SHARES; SHARES ACQUIRED ON OR AFTER DATE OF DISSENTER'S
  NOTICE.
 
    1.  A subject corporation may elect to withhold payments from a dissenter
unless he was the beneficial owner of the shares before the date set forth in
the dissenter's notice as the date of the first announcement to the news media
or to the stockholders of the terms of the proposed action.
 
    2.  To the extent the subject corporation elects to withhold payment, after
taking the proposed action, it shall estimate the fair value of the shares, plus
accrued interest, and shall offer to pay this amount to each dissenter who
agrees to accept it in full satisfaction of his demand. The subject corporation
shall send with its offer a statement of its estimate of the fair value of the
shares, an explanation of how the interest was calculated, and a statement of
the dissenters' right to demand payment pursuant to NRS 92A.480.
 
92A.480. DISSENTER'S ESTIMATE OF FAIR VALUE; NOTIFICATION OF SUBJECT
  CORPORATION; DEMAND FOR PAYMENT OF ESTIMATE.
 
    1.  A dissenter may notify the subject corporation in writing of his own
estimate of the fair value of his shares and the amount of interest due, and
demand payment of his estimate, less any payment pursuant to NRS 92A.460, or
reject the offer pursuant to NRS 92A.470 and demand payment of the fair value of
his shares and interest due, if he believes that the amount paid pursuant to NRS
92A.460 or offered pursuant to NRS 92A.470 is less than the fair value of his
shares or that the interest due is incorrectly calculated.
 
    2.  A dissenter waives his right to demand payment pursuant to this section
unless he notifies the subject corporation of his demand in writing within 30
days after the subject corporation made or offered payment for his shares.
 
92A.490. LEGAL PROCEEDING TO DETERMINE FAIR VALUE; DUTIES OF SUBJECT
  CORPORATION; POWERS OF COURT; RIGHTS OF DISSENTER.
 
    1.  If a demand for payment remains unsettled, the subject corporation shall
commence a proceeding within 60 days after receiving the demand and petition the
court to determine the fair value of the shares and accrued interest. If the
subject corporation does not commence the proceeding within the 60-day period,
it shall pay each dissenter whose demand remains unsettled the amount demanded.
 
    2.  A subject corporation shall commence the proceeding in the district
court of the county where its registered office is located. If the subject
corporation is a foreign entity without a resident agent in the state, it shall
commence the proceeding in the county where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
entity was located.
 
    3.  The subject corporation shall make all dissenters, whether or not
residents of Nevada, whose demands remain unsettled, parties to the proceeding
as to an action against their shares. All parties must be served with a copy of
the petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.
 
    4.  The jurisdiction of the court in which the proceeding is commenced under
subsection 2 is plenary and exclusive. The court may appoint one or more persons
as appraisers to receive evidence and recommend a decision on the question of
fair value. The appraisers have the powers described in the order appointing
them, or any amendment thereto. The dissenters are entitled to the same
discovery rights as parties in other civil proceedings.
 
                                       5
<PAGE>
    5.  Each dissenter who is made a party to the proceeding is entitled to a
judgment:
 
        (a) For the amount, if any, by which the court finds the fair value of
    his shares, plus interest, exceeds the amount paid by the subject
    corporation; or
 
        (b) For the fair value, plus accrued interest, of his after-acquired
    shares for which the subject corporation elected to withhold payment
    pursuant to NRS 92A.470.
 
92A.500. LEGAL PROCEEDING TO DETERMINE FAIR VALUE; ASSESSMENT OF COSTS AND FEES.
 
    1.  The court in a proceeding to determine fair value shall determine all of
the costs of the proceeding, including the reasonable compensation and expenses
of any appraisers appointed by the court. The court shall assess the costs
against the subject corporation, except that the court may assess costs against
all or some of the dissenters, in amounts the court finds equitable, to the
extent the court finds the dissenters acted arbitrarily, vexatiously or not in
good faith in demanding payment.
 
    2.  The court may also assess the fees and expenses of the counsel and
experts for the respective parties, in amounts the court finds equitable:
 
        (a) Against the subject corporation and in favor of all dissenters if
    the court finds the subject corporation did not substantially comply with
    the requirements of NRS 92A.300 to 92A.500, inclusive; or
 
        (b) Against either the subject corporation or a dissenter in favor of
    any other party, if the court finds that the party against whom the fees and
    expenses are assessed acted arbitrarily, vexatiously or not in good faith
    with respect to the rights provided by NRS 92A.300 to 92A.500, inclusive.
 
    3.  If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the subject corporation, the
court may award to those counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefited.
 
    4.  In a proceeding commenced pursuant to NRS 92A.460, the court may assess
the costs against the subject corporation, except that the court may assess
costs against all or some of the dissenters who are parties to the proceeding,
in amounts the court finds equitable, to the extent the court finds that such
parties did not act in good faith in instituting the proceeding.
 
    5.  This section does not preclude any party in a proceeding commenced

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 145 of the Delaware General Corporation Law (the "DGCL") authorizes
a court to award or a corporation's board of directors to grant indemnification
to directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act.
 
    As authorized by Section 102(b)(7) of the DGCL, Sun's Certificate of
Incorporation limits the personal liability of each Sun director to Sun or its
stockholders for monetary damages for breach of his fiduciary duty as a director
except to the extent such limitation of liability is not permitted under the
DGCL. The DGCL provides that the liability of a director may not be limited (i)
for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (iii) for liability for
payment of dividends or stock purchases or redemptions in violation of the DGCL
or (iv) for any transaction from which the director derived an improper personal
benefit.
 
    In addition, Sun's Bylaws provide that Sun shall indemnify any and all of
its directors, or former directors, to the fullest extent permitted by law
against claims and liabilities to which such persons may become subject. The
DGCL provides that indemnification is permissible only when the director acted
in good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the conduct was unlawful. The
DGCL also permits indemnification in respect of any claim, issue, or matter as
to which such person shall have been adjudicated to be liable to the corporation
to the extent that the Delaware Court of Chancery or the court in which such
action or suit was brought has determined upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity. Sun has also entered into
indemnification agreements with certain of its officers and with its directors
and also provides insurance coverage to such parties.

ITEM 22. UNDERTAKINGS.
 
    (a) The undersigned registrant hereby undertakes (i) to file, during any
period in which offers or sales are being made, a post-effective amendment to
this registration statement (A) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933; (B) 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; and (C) 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; (ii) that, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof; and (iii) to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.
 
    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.
 
    (c) (i) 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.
 
                                      II-4
<PAGE>
        (ii) The undersigned registrant hereby undertakes that every prospectus:
             (A) that is filed pursuant to paragraph (c) immediately preceding
             or (B) that purports to meet the requirements of Section 10(a)(3)
             of the Securities Act of 1933 and is used in connection with an
             offering of securities subject to Rule 415, will be filed as a part
             of an amendment to the registration statement and will not be used
             until such amendment is effective, and that, for purposes of
             determining any liability under the Securities Act of 1933, each
             such post-effective amendment shall be deemed to be a new
             registration statement relating to the securities offered therein,
             and the offering of such securities at that time shall be deemed to
             be the initial BONA FIDE offering thereof.
 
    (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable. In the event that such a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
 
    (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference in the Joint Proxy
Statement/Prospectus/Information Statement pursuant to Item 4, 10(b), 11 or 13
of this form, within one business day of receipt of such request, and to send
the incorporated documents by first class mail or other equally prompt means.
This includes information contained in documents filed subsequent to the
effective date of the registration statement through the date of responding to
the request.
 
    (f) 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.

                        CERTIFICATE OF DESIGNATIONS
                                      OF
                     SERIES B CONVERTIBLE PREFERRED STOCK

     Sun Healthcare Group, Inc., a corporation organized and existing under 
the General Corporation Law of the State of Delaware (the "Corporation"), 
hereby certifies that the following resolution was adopted by the Board of 
Directors of the Company as required by Section 151 of the General 
Corporation Law at a meeting duly called and held on February 13, 1997:

          RESOLVED, that pursuant to the authority granted to and vested in 
     the Board of Directors of the Company (the "Board of Directors" or the 
     "Board") in accordance with the Company's Certificate of Incorporation, 
     as amended to date (the "Certificate of Incorporation"), the Board of 
     Directors hereby creates a series of preferred stock, par value $.01 per 
     share, of the Company and hereby states the designation and number of 
     shares, and fixes the relative rights, preferences, and limitations 
     thereof as follows:

     Section 1.  DESIGNATION AND AMOUNT.  There is hereby established a 
series of Preferred Stock of the Corporation designated "Series B Convertible 
Preferred Stock." The number of shares of this series of Convertible 
Preferred Stock shall be 300,000 shares.

     Section 2.  CONVERSION RIGHTS.

     a.  RIGHT TO CONVERT.  Each share of Series B Convertible Preferred 
Stock may be converted at the option of the holder thereof at any time and 
from time to time, and without the payment of any additional consideration 
thereof, into _______ fully paid, nonassessable shares of common stock, $.01  
par value per share (the "Conversion Price"), of the Corporation (the "Common 
Stock").

     b.  AUTOMATIC CONVERSION.  Each share of Series B Convertible Preferred 
Stock not previously converted at the election of the holder thereof shall 
automatically be converted into shares of Common Stock on October 2, 1998.


<PAGE>

     c.  MECHANICS OF CONVERSION.

         (i)  No fractional shares of Common Stock shall be issued upon 
conversion of Series B Convertible Preferred Stock. In lieu of any fractional 
shares to which the holder would otherwise be entitled, the Corporation shall 
round up to the nearest whole share. In the case of a dispute as to the 
calculation of the Conversion Price, the Corporation's calculations shall be 
deemed conclusive absent manifest error. In order to convert Series B 
Convertible Preferred Stock into full shares of Common Stock, the holder 
shall surrender the certificate or certificates therefor, duly endorsed, 
either by overnight courier or 2-day courier, to the Corporation or its 
designated representative, and shall give written notice to the Corporation, 
with a copy to such representative that the holder elects to convert the 
same, the number of shares of Series B Convertible Preferred Stock so 
converted and a calculation of the Conversion Price (with an advance copy of 
the certificate(s) and the notice by facsimile to the Corporation, with a 
copy to such representative); provided, however, that the Corporation shall 
not be obligated to issue certificates evidencing shares of Common Stock 
issuable upon such conversion unless certificates evidencing such shares of 
Series B Convertible Preferred Stock are delivered to the Corporation or its 
designated representative as provided above, or the holder notifies the 
Corporation that such certificates have been lost, stolen or destroyed and 
executes an agreement satisfactory to the Corporation to indemnify the 
Corporation from any loss incurred by it in connection with such certificates.

        (ii)  The Corporation shall use its best efforts to issue and deliver 
within three (3) business days after delivery to the Corporation or its 
designated representative of such Series B Convertible Preferred Stock 
certificates, or after such agreement and indemnification, to such holder of 
Series B Convertible Preferred Stock at the address of the holder on the 
stock books of the Corporation, a certificate or certificates for the number 
of shares of Common Stock to which the holder shall be entitled as aforesaid, 
free of any restrictive legend. The Corporation shall not be deemed to have 
used its best efforts it its failure so to deliver such certificates is 
caused by (x) a lack of sufficient authorized but unissued shares of Common 
Stock available to effect conversion or (y) non-compliance with the New York 
Stock Exchange's requirements as to the listing of additional shares or 
shareholder approval of additional issuances of stock. The date on which 
conversion occurs (the "Date of Conversion") shall be deemed to be the date 
on which such notice of conversion is telecopied to the Corporation or its 
designated representative, provided the original certificates representing 
the shares of Series B Convertible Preferred Stock to be converted are 
received by  the Corporation or its designated representative within three 
(3) business days thereafter, and the person or persons entitled to receive 
the shares of Common Stock issuable upon such conversion shall be treated for 
all purposes as the record holder or holders of such shares of Common Stock 
on the Date of Conversion. If the original certificates representing the 
shares of Series B Convertible Preferred Stock to be converted are not so 
received by the Corporation or its designated representative within such 
three (3) business day period, the notice of conversion shall become null and 
void.

     Section 3.  CORPORATE EVENTS.

     a.  NOTICES OF RECORD DATE.  In the event of (i) any declaration by the 
Corporation of a record date of the holders of any class of securities for 
the purpose of determining the holders thereof who are entitled to receive 
any dividend or other distribution of (ii) any capital reorganization of the 
Corporation, any reclassification or recapitalization of the capital stock of 
the Corporation, any merger or consolidation of the Corporation and any other 
entity or person, or any voluntary or involuntary dissolution, liquidation or 
winding up of the Corporation, the Corporation shall mail to each holder of 
Series B Convertible Preferred Stock at least twenty (20) days prior to the 
record date specified herein, a notice specifying (A) the date on which any 
such record date is to be declared for the purpose of such dividend or 
distribution and a description of such dividend or distribution, (B) the date 
on which any such reorganization, reclassification, transfer, consolidation, 
merger, dissolution, liquidation or winding up is expected to become 
effective, and (C) the time, if any, that is to be fixed, as to when the 
holders of record of Common Stock (or other securities) become eligible to 
receive securities or other property deliverable upon such reorganization, 
reclassification, transfer, consolidation, merger, dissolution or winding up.

     b.  CORPORATE CHANGES.  The Conversion Price shall be appropriately 
adjusted to reflect, as deemed equitable and appropriate by the corporation, 
any stock dividend, stock split or share combination of the Common Stock. In 
the event of a merger, reorganization, recapitalization or similar event of 
or with respect to the Corporation (a "Corporate Change") (other than a
Corporate Change in which all or substantially all of the consideration 
received by the holders of the Corporation's equity securities upon such 
Corporate Change consists of cash or assets other than securities issued by 
the acquiring entity or any affiliate thereof), the Series B Convertible 
Preferred Stock shall be assumed by the acquiring entity and thereafter the 
Series B Convertible Preferred Stock shall be convertible into such class and 
type of securities as the holder would have received had the holder converted 
the Series B Convertible Preferred Stock immediately prior to such Corporate 
Change, as appropriately adjusted to equitably reflect the Conversion Price and 
any stock dividend, stock split or share combination of the Common Stock 
after such corporate event, and in any such case appropriate provisions shall 
be made with respect to the rights and interests of the holders of the 
Series B Convertible Preferred Stock to the end that the provisions hereof 
(including, without limitation, provisions for the adjustment of the 
Conversion Price and of the number of shares issuable upon conversion of the 
Series B Convertible Preferred Stock) shall thereafter be applicable, as 
nearly as may be practicable in relation to any securities thereafter 
deliverable upon the exercise hereof.

     Section 4.  SPIN OFFS, LIQUIDATING DISTRIBUTIONS.  In the event that the 
Corporation shall make any distribution of its assets upon or with respect to 
its Common Stock, as a liquidating or partial liquidating dividend, or other 
than as a dividend payable out of earnings or any surplus legally available 
for dividends under the laws of the state of incorporation of the 
Corporation, each holder of any Series B Convertible Preferred Stock then 
outstanding shall receive the amount of such assets which would be 
distributed to such holder if he had exercised his right to convert 
immediately prior 

<PAGE>

to the record date for such distribution or, in the absence of a record date, 
immediately prior to the date of such distribution.

     Section 5.  RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  The 
Corporation shall at all times reserve and keep available out of its 
authorized but unissued shares of Common Stock solely for the purpose of 
effecting the conversion of the shares of Series B Convertible Preferred 
Stock such number of its shares of Common Stock as shall from time to time be 
sufficient to effect the conversion of all then outstanding shares of 
Series B Convertible Preferred Stock; and if at any time the number of 
authorized but unissued shares of Common Stock shall not be sufficient to 
affect the conversion of all then outstanding shares of the Series B 
Convertible Preferred Stock, the Corporation will take such corporate action 
as may be necessary to increase its authorized but unissued shares of Common 
Stock to such number of shares as shall be sufficient for such purpose.

     Section 6.  LIQUIDATION PREFERENCE.

     a.  In the event of any liquidation, dissolution or winding up of the 
Corporation (other than a partial liquidation described in Section 3(b)), 
either voluntary or involuntary, the holders of shares of Series B 
Convertible Preferred Stock shall be entitled to receive, immediately after 
distributions of senior securities required by the Corporation's Certificate 
of Incorporation, and prior and in preference to any distribution to 
junior securities but in parity with any distribution to parity securities, 
an amount per share [equal to the sum of (i) $10.00 and (ii) an amount equal 
to $0.40 per annum for the period from October 2, 1996 to the date of such 
liquidation, dissolution or winding up. If upon the occurrence of such event 
the assets and funds thus distributed among the holders of the Series B 
Convertible Preferred Stock and parity securities shall be insufficient to 
permit the payment to such holders of the full preferential amounts due to 
the holders of the Series B Convertible Preferred Stock and the parity 
securities, respectively, then the entire assets and funds of the Corporation 
legally available for distribution shall be distributed among the holders of 
the Series B Convertible Preferred Stock and the parity securities, pro rata, 
based on the respective liquidation amounts to which such series of stock is 
entitled by the Corporation's Certificate of Incorporation.

     b.  Upon the completion of the distribution required by subsection 6(a), 
if assets remain in this Corporation, they shall be distributed to holders of 
parity securities (unless holders of parity securities have received 
distributions pursuant to subsection 6(a) above) and junior securities in 
accordance with the Corporation's Certificate of Incorporation.

     c.  A consolidation or merger of the Corporation with or into any other 
corporation or corporations, or a sale, conveyance or distribution of all or 
substantially all of the assets of the Corporation or the effectuation by the 
Corporation of a transaction or series of related transactions in which more 
than 50% of the voting power of the Corporation is 

<PAGE>

disposed of, shall not be deemed to be a liquidation, dissolution or winding 
up within the meaning of this Section 6, but shall instead be treated pursuant 
to Section 3 hereof.

     Section 7.  VOTING RIGHTS.

     a.  The holders of Series B Convertible Preferred Stock will have the 
same voting rights as holders of the Common Stock, except as set forth below 
or as otherwise from time to time required by law.

     b.  The holders of Series B Convertible Preferred Stock shall be 
entitled to vote with the holders of Common Stock, voting together with such 
holders as one class, on all matters for which the holders of Common Stock 
are entitled to vote, with each share of Series B Convertible Preferred Stock 
entitled to a number of votes equal to the number of shares of Common Stock 
into which it is then convertible using the record date for the taking of 
such vote of stockholders as the date as of which the Conversion Price is 
calculated.

     c.  The affirmative vote or consent of the holders of at least a 
majority of the outstanding shares of Series B Convertible Preferred Stock, 
voting separately as a class, will be required for an amendment, alteration 
or repeal of the Corporation's Certificate of Incorporation if, and only if, 
the amendment, alteration or repeal adversely affects the powers, preferences 
or special rights of the Series B Convertible Preferred Stock.

     d.  To the extent that under Delaware law the vote of the holders of the 
Series B Convertible Preferred Stock, voting separately as a class, is 
required to authorize a given action of the Corporation, the affirmative vote 
or consent of the holders of at least a majority of the outstanding shares of 
the Series B Convertible Preferred Stock shall constitute the approval of 
such action by the class.  Holders of the Series B Convertible Preferred 
Stock shall be entitled to notice of all shareholders meetings or written 
consents with respect to which they would be entitled to vote, which notice 
would be provided pursuant to the Corporation's by-laws and applicable 
statutes.

     Section 8.  PROTECTIVE PROVISIONS.  So long as shares of Series B 
Convertible Preferred Stock are outstanding, the Corporation shall not take 
any action that would impair the rights of the holders of the Series B 
Convertible Preferred Stock set forth herein and shall not without first 
obtaining the approval (by vote or written consent, as provided by law) of 
all of the holders of the then outstanding shares of Series B Convertible 
Preferred Stock;

<PAGE>

     a.  alter or change the rights, preferences or privileges of the shares 
of the Series B Convertible Preferred Stock or any other securities so as to 
affect adversely the Series B Convertible Preferred Stock;

     b.  create any new class of stock having a preference over, or being on 
a parity with, the Series B Convertible Preferred Stock with respect to 
distributions pursuant to Section 6 above; or

     c.  do any act or thing which would result in taxation of the holders of 
shares of the Series B Convertible Preferred Stock under Section 305 of the 
Internal Revenue Code of 1986, as amended (or any comparable provision of the 
Internal Revenue Code as hereinafter from time to time amended).

     Section 9.    STATUS OF CONVERTED OR REACQUIRED STOCK.  In case any shares 
of Series B Convertible Preferred Stock shall be converted Pursuant to 
Section 2 hereof the shares so converted shall cease to be a part of the 
authorized capital stock of the Corporation

     Section 10.  DIVIDEND PROVISIONS.  The holders of shares of the Series B 
Convertible Preferred Stock are not entitled to receive any dividends.

     Section 11.  NOTICES.  Any notice required to be given to holders of 
shares of Series B Convertible Preferred Stock shall be deemed given upon 
deposit in the United States mail, postage prepaid, addressed to such holder 
of record at his address appearing on the books of the Corporation, or upon

Sun Healthcare Group, Inc.
101 Sun Lane, NE
Albuquerque, New Mexico 87109

Ladies and Gentlemen:

  We have acted as counsel for Sun Healthcare Group, Inc., a Delaware 
corporation ("Sun"), in connection with the preparation, execution and 
delivery of the Agreement and Plan of Merger and Reorganization, dated as of 
February 17, 1997, as amended by Amendment No.1 thereto dated as of May 27, 
1997 and Amendment No. 2 thereto dated as of August 21, 1997, Amendment No. 3 
thereto dated as of November 25, 1997 and Amendment No. 4 thereto dated as of 
April 3, 1998 (as amended, the "RCA Merger Agreement"), among Sun Peach 
Acquisition Corporation, a Colorado Corporation ("Merger Sub") and Retirement 
Care Associates, Inc., a Colorado Corporation ("RCA"), and documents related 
or incidental thereto and transactions to be effected thereunder.  You have 
requested our opinion concerning certain United States federal income tax 
consequences of the exchange by RCA Stockholders of RCA Common Stock and RCA 
Series AA Redeemable Preferred Stock for Sun Common Stock, and the exchange 
by RCA Stockholders of RCA Series F Preferred Stock for Series B Convertible 
Preferred Stock of Sun (both exchanges collectively referred to as the 
"Exchange"), and the merger of Merger Sub with and into RCA (the "Merger") 
pursuant to the Merger Agreement.  Unless otherwise defined, capitalized 
terms used herein have the meanings assigned to them in the Merger Agreement.

<PAGE>

  In delivering this opinion, we have reviewed and relied upon facts and 
descriptions set forth in the Registration Statement, the Merger Agreement 
and related documents pertaining to the Exchange and the Merger.  We also 
have relied upon certificates of officers of Sun and the Company (the 
"Officers' Certificates").  We have assumed that the Officers' Certificates, 
respectively, have been executed and delivered by appropriate officers of Sun 
and RCA and are true and correct.  We also have assumed that the 
certifications made in the Officers' Certificates, respectively, will 
continue to be true and correct as of the Effective Time unless we receive 
written notification from Sun or RCA prior to the Effective Time.  In 
addition, we have assumed that all statements to be made in the Officers' 
Certificates "to the best of the knowledge" of any person or party to the 
Merger will be correct as if made without such qualification.

  Based on the foregoing and the Code, the Income Tax Regulations issued by 
the United States Treasury Department thereunder, rulings of the Internal 
Revenue Service and court decisions, all as in effect on the date hereof, we 
are of the opinion that if the Exchange and the Merger is completed in 
accordance with the terms and conditions of the Merger Agreement, and if the 
statements set forth in the Officers' Certificates are true and correct on 
the date hereof, on the effective date of the Registration Statement and at 
the time of the Exchange and the Merger, for federal income tax purposes:

      1.  The Merger will constitute a reorganization within the meaning of 
   Section 368 of the Code.

      2.  Sun, RCA and Merger Sub will constitute parties to such 
   reorganization within the meaning of Section 368(b) of the Code.

<PAGE>

      3.  The discussion entitled "Certain Federal Income Tax Consequences" in 
the Joint Proxy Statement/Prospectus of the Registration Statement, insofar as 
it relates to statements of law or legal conclusions, is correct in all material
respects.

  We hereby consent to the use of our name under the heading "Certain Federal 
Income Tax Consequences" in the prospectus and to the filing of this opinion 
as Exhibit 8.1 to the Registration Statement.

  In accordance with customary practice relating to opinion letters, our 
opinions speak only as of the date hereof, and, subject to the assumptions 
and conditions set forth above, the effective time of the Exchange and the 
Merger, and we disclaim any duty to update such opinions.


                                       Very truly yours,

     Re:  FEDERAL INCOME TAX CONSEQUENCES OF THE PROPOSED MERGER OF
          PEACH ACQUISITION CORPORATION WITH AND INTO RETIREMENT CARE 
          ASSOCIATES, INC.

Gentlemen:

     We have acted as counsel for Retirement Care Associates, Inc. ("RCA") in 
connection with the proposed merger (the "RCA Merger") of Peach Acquisition 
Corporation ("Sun Merger Sub"), a Colorado corporation and wholly-owned 
subsidiary of Sun Healthcare Group, Inc. ("Sun"), with and into RCA, pursuant 
to that certain Agreement and Plan of Merger and Reorganization dated as of 
February 17, 1997, as amended by Amendment No. 1 thereto dated as of May 27, 
1997, Amendment No. 2 thereto dated as of August 21, 1997 and Amendment No. 3 
thereto dated as of November 25, 1997, and Amendment No. 4 thereto dated as 
of April 3, 1998, by and among RCA, Sun Merger Sub and Sun (as so amended, 
the "RCA Merger Agreement"). In our capacity as counsel for RCA and as 
provided in the RCA Merger Agreement, we have been requested to render our 
opinion regarding certain of the federal income tax consequences of the RCA 
Merger.

     We understand that this opinion will be filed as an exhibit as an 
exhibit to the Registration Statement on Form S-4 (the "Registration 
Statement") that will be filed by Sun with the Securities and Exchange 
Commission relating to the securities that will be issued by Sun pursuant to 
the RCA Merger Agreement and that this opinion will be referred to in the 
Joint Proxy Statement/Prospectus/Information Statement that will be a part of 
the Registration Statement. We hereby consent to such use of and reference to 
this opinion.

     All terms used herein without definition shall have the respective 
meanings specified in the RCA Merger Agreement and, unless otherwise 
indicated, all section references herein are to the Internal Revenue Code of 
1986, as amended.

                           INFORMATION RELIED UPON

     In rendering this opinion, we have examined such documents as we have 
deemed appropriate, including the RCA Merger Agreement and the Registration 
Statement. In the course of such examination, we have assumed, with your 
consent, that all documents submitted to us as photocopies faithfully 
reproduce the originals thereof, that all such originals are authentic, that 
all such documents have been or will be duly executed to the extent required, 
and that all statements set forth in such documents are accurate. We have also 
obtained such additional information and representations as we have deemed 
relevant and necessary through consultations with various representatives of 
RCA and Sun. In addition, we have obtained written certificates from the 
managements of RCA and Sun to verify certain relevant facts that have been 
represented to us or that we have assumed in rendering this opinion. Such 
certificates are attached as Exhibits to this opinion. With your consent, we 
have assumed that the representations made in such certificates are true on 
the date hereof and will be true at the Effective Time.

                                   OPINION

     Based upon the foregoing, it is our opinion that:

     1.  The RCA Merger will qualify as a "reorganization" within the meaning 
of Section 368 of the Code, and of each RCA, Sun Merger Sub and Sun will be "a 
party to a reorganization" within the meaning of Section 368(b).

     2.  No gain or loss will be recognized by RCA or Sun in the RCA Merger.

     3.  No gain or loss will be recognized by holders of RCA Capital Stock 
upon their receipt of Sun Common Stock or Sun Preferred Stock, as the case 
may be, in exchange for their RCA Capital Stock, except that holders of RCA 
Capital Stock who receive cash proceeds in lieu of fractional shares of Sun 
Common Stock will recognize gain or loss equal to the difference, if any, 
between such proceeds and the tax basis of RCA Capital Stock allocated to 
their fractional share interests.

     4.  The tax basis of Sun Common Stock or Sun Preferred Stock, as the 
case may be, received by holders of RCA Capital Stock will be the same as the 
tax basis of RCA Capital Stock exchanged therefor less the tax basis, if any, 
allocated to fractional share interests.

     5.  The holding period of Sun Common Stock or Sun Preferred Stock, as 
the case may be, in the hands of holders of RCA Common Stock will include the 
holding period of their RCA Capital Stock exchanged therefor, provided that 
such RCA Capital Stock is held as a capital asset at the time of the RCA 
Merger.

Sun Healthcare Group, Inc.
101 Sun Lane, NE
Albuquerque, New Mexico 87109
 
Ladies and Gentlemen:
 
    We have acted as special tax counsel for Sun Healthcare Group, Inc., a
Delaware corporation ("Sun"), in connection with the preparation, execution and
delivery of the Agreement and Plan of Merger and Reorganization, dated as of
February 17, 1997, as amended by Amendment No. 1 thereto dated as of August 21,
1997, Amendment No. 2 thereto dated as of November 25, 1997 and Amendment No. 3
thereto dated as of April 3, 1998 (as amended, the "Contour Merger Agreement"),
among Sun, Contour Medical, Inc., a Nevada corporation ("Contour"), and
Nectarine Acquisition Corporation, a Nevada corporation and a direct
wholly-owned subsidiary of Sun ("Contour Merger Sub"), and documents related or
incidental thereto and transactions to be effected thereunder. You have
requested our opinion concerning certain United States federal income tax
consequences of the exchange by the holders of Contour Common Stock and Series A
Preferred Stock of Contour for Sun Common Stock, and the merger of Merger Sub
with and into Contour (the "Contour Merger") pursuant to the Contour Merger
Agreement. Unless otherwise defined, capitalized terms used herein have the
meanings assigned to them in the Contour Merger Agreement or in the Joint Proxy
Statement/Prospectus of the Registration Statement. All section references
herein are made to the corresponding section of the Internal Revenue Code of
1986, as amended (the "Code").
 
    At the Contour Effective Time, each share of Contour Capital Stock issued
and outstanding immediately prior to the Contour Effective Time, other than the
shares owned by RCA, will be converted into shares of Sun Common Stock. Each
outstanding share of Contour Capital Stock owned by RCA will not be exchanged in
the Contour Merger and will remain outstanding unless (i) the RCA Merger does
not occur promptly after the consummation of the Contour Merger, or (ii) Sun
does not undertake to contribute to RCA all shares of Contour Capital Stock
obtained by Sun pursuant to the Contour Merger (the "Contribution"), in which
event RCA would receive the same per share consideration as the other holders of
Contour Capital Stock. If the RCA Merger occurs, Sun intends to complete the
Contribution.
<PAGE>
    In delivering this opinion, we have reviewed and relied upon facts and
descriptions set forth in the Registration Statement, the Contour Merger
Agreement and related documents pertaining to the Contour Merger. We also have
relied upon certificates of officers of Sun and Contour (the "Officers'
Certificates"). We have assumed that the Officers' Certificates, respectively,
have been executed and delivered by appropriate officers of Sun and Contour and
are true and correct. We also have assumed that the certifications made in the
Officers' Certificates, respectively, will continue to be true and correct as of
the Effective Time unless we receive written notification from Sun or Contour
prior to the Effective Time. In addition, we have assumed that all statements to
be made in the Officers' Certificates "to the best of the knowledge" of any
person or party to the Contour Merger will be correct as if made without such
qualification.
 
    Based on the foregoing and the Code, the Income Tax Regulations issued by
the United States Treasury Department thereunder, rulings of the Internal
Revenue Service and court decisions, all as in effect on the date hereof, we are
of the opinion that if the Contour Merger is completed in accordance with the
terms and conditions of the Contour Merger Agreement, and if the statements set
forth in the Officers' Certificates are true and correct on the date hereof,
assuming that the RCA Merger and the Contribution occur promptly after the
Contour Merger, on the effective date of the Registration Statement and at the
time of the Contour Merger, for federal income tax purposes:
 
        1.  The Contour Merger would more likely than not constitute a
    reorganization within the meaning of section 368 of the Code. In such a
    case, the material federal income tax consequences of the Contour Merger to
    Contour and the holders of Contour Capital Stock will be as follows: (a) no
    gain or loss will be recognized by Contour, Sun or RCA in the Contour
    Merger; (b) no gain or loss will be recognized by holders of Contour Capital
    Stock upon their receipt of Sun Common Stock in exchange for the Contour
    Capital Stock, except that holders of Contour Capital Stock who receive cash
    proceeds in lieu of fractional shares of Sun Common Stock will recognize
    gain or loss equal to the difference, if any, between such proceeds and the
    tax basis of Contour Capital Stock allocated to their fractional share
    interest; (c) such gain or loss, if any, will constitute capital gain or
    loss if fractional share interests exchanged are held as capital assets at
    the time of the Contour Merger; (d) such capital gain or loss will be
    long-term capital gain or loss if the holding period for the fraction share
    interests (including the holding period of Contour Capital Stock attributed
    thereto as described below) exceeds one year; (e) the tax basis of the Sun
    Common Stock received by the holders of Contour Capital Stock will be the
    same as the tax basis of the Contour Capital Stock exchanged therefor less
    the tax basis, if any, allocated to fractional share interests; and (f) the
    holding period of Sun Common Stock in the hands of holders of Contour
    Capital Stock will include the holding period of the Contour Capital Stock
    exchanged therefor; provided that such Contour Capital Stock is held as a
    capital asset at the time of the Contour Merger.

        2.  By issuing this opinion, we confirm that the discussions set forth
    in the "Summary--The Contour Merger; Certain Federal Income Tax
    Consequences" section and the "The Contour Merger--Certain Federal Income
    Tax Consequences" section of the Joint Proxy Statement/Prospectus, insofar
    as both sections relate to statements of law or legal conclusions, are
    correct in all material respects.
 
    With regard to opinion number one above, pursuant to section 368(a)(1)(B) of
the Code, a reorganization includes an acquisition by one corporation, in
exchange solely for all or a part of the voting stock of a corporation which is
in control of the acquiring corporation within the meaning of section 368(c) of
the Code ("Control"), of the stock of another corporation if, immediately after
the acquisition, the acquiring corporation is in Control of such other
corporation. We believe that the Contour Merger, the RCA Merger and the
Contribution (the "Transactions") are closely connected in terms of their
timing, economic consequences and the parties' expectations and intent, and,
therefore, the end result of the Transactions, which is consistent with
reorganization treatment for federal income tax purposes, should govern. There
exists authority, however, for determining the federal income tax consequences
of each step in a multi-step transaction on an independent basis. Nevertheless,
we believe that such authority should not be controlling in the present case.
 
    We hereby consent to the use of our name under the heading "Certain Federal
Income Tax Consequences" in the prospectus and to the filing of this opinion as
Exhibit 8.1 to the Registration Statement.
 
    In accordance with customary practice relating to opinion letters, our
opinions speak only as of the date hereof, and, subject to the assumptions and
conditions set forth above, the effective time of the Contour Merger, and we
disclaim any duty to update such opinions.
 
    This opinion has been delivered to you solely for the purpose of being
included as an exhibit to the Registration Statement. It may not be relied upon
for any other purpose or by any other person or entity, other than the
shareholders of Contour, and may not be made available to any other person or
entity without our prior written consent.
 
                                          Very truly yours,
                                          /s/ SHEARMAN & STERLING
